UN SUSTAINABLE DEVELOPMENT GOALS

UN SUSTAINABLE DEVELOPMENT GOALS Organized by goal/start time/department

This year, for the first time, the Stander Symposium asked students to choose two of the 17 United Nations Sustainable Development Goals which most closely align with the project they are presenting. In choosing a Global Goal we hope students will be inspired to identify ways their work at UD with connects with international initiatives and consider new ways their scholarship, research and creative activities can be leveraged for the Common Good. Sessions have been organized based on Goals to generate new trans-disciplinary conversations. Details on the Sustainable Development Goals (SDG) can be found at https://www.globalgoals.org/.

UN SUSTAINABLE DEVELOPMENT GOALS

Poverty and Education

School of Education and Health Sciences: Teacher Education Poster | Course Project, 201910 EDT 110 H1 Goal 1: No Poverty Goal 2: Zero Hunger STUDENTS Alexandra Gisela Delgrande, Ryan Earl Evensen-Hein ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Poverty affects at-risk students’ academic opportunity through its effects on academic achievement, motivation, development, and education quality. Impoverished at-risk students’ academic achievement is affected by their inability to acquire basic needs. This can be shown by these students’ graduation rates, math scores, and retention rates. There is evidence of poverty having a negative effect on graduation rates, retention rates, and test scores. These students’ can appear less motivated or less engaged in the classroom potentially due to their focus on higher priorities. How could you expect a student to worry about a math test when they do not know how they are getting dinner that night? Since these students are unable to acquire their basic needs, they can also encounter developmental problems. These developmental issues refer to social, emotional, and cognitive development as well as can lead to malnutrition and preterm birth. These developmental setbacks hinder these students’ ability to further develop in school. Another obstacle impoverished students can face is poor education quality. Oftentimes, inexperienced or ineffective educators are assigned to schools with higher impoverished student populations. This unfortunate fact, as well as underfunded districts, and the lack of basic school supplies, further disadvantage impoverished at-risk students. Impoverished at-risk students are put at a disadvantage through poverty’s effects on academic achievement, motivation, retention, development, and education quality.

Snapshot: Miracles in Focus

College of Arts and Sciences: Communication Documentary - Independent Research Goal 1: No Poverty Goal 4: Quality Education STUDENTS Tom E Cook ADVISORS Jesseca Y Simmons LOCATION, TIME Sears Recital Hall, 9:20-9:40 This documentary follows students and parents in the after school Miracle Makers program at Ruskin Elementary participating in PhotoVoice. PhotoVoice is an initiative dedicated to giving a voice to voiceless. Participants tell their stories by taking photos of their lives in order to promote critical dialogue and knowledge about important issues in the community. The goal is to break down biases towards those living in poverty through photos. The doc follows students and parents through the first day of the project until the final exposition.

Human Rights and the Omaha and Winnebago Tribes College of Arts and Sciences: Political Science Oral Presentation - Capstone Project Goal 1: No Poverty Goal 10: Reduced Inequalities STUDENTS Tiffany Erin Hendricks ADVISORS Joel Richard Pruce LOCATION, TIME Marianist Hall Learning Space 218, 10:00-10:20 Through decades of political, economic, and social exclusion, the Native American communities have been termed our “forgotten brothers and sisters,” to the point that these tribal people have been restricted of rights and left in a state of abject poverty and overlooked struggles. This spring break, I traveled to Omaha, Nebraska to serve on reservation with the Omaha and Winnebago tribal communities with the Fellowship of Catholic University Students (FOCUS) missionary team. During my time in Nebraska, I assisted educational leaders in classrooms, worked with village elders on community projects, and participated in assignments facilitated by the Hope of the Poor foundation to combat the aggregate effects of poverty and addiction in these areas. I also joined in local events that helped me to better understand and learn more from a general standpoint about the Winnebago and Omaha tribal cultures, as well as engaged in dialogue that detailed different struggles of the community in relation to human rights and socioeconomic and political participation on a national scale. In this oral presentation, I will focus on the causes, conditions, and effects of human rights infringements on the Native American tribes in Nebraska.

Poverty Redemption: Why Those Affected Stay Affected

College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project Goal 1: No Poverty STUDENTS Claudia Margot Hampel ADVISORS Leslie H Picca LOCATION, TIME Kennedy Union 211, 10:40-11:00 This paper looks at why those in poverty do not participate in self-sufficiency programs that are offered through Miami Valley Works along with other self-sufficiency programs offered. This paper looks at the multiple factors that could contribute to why those in poverty do not go through self-sufficiency programs, whether they chose not to participate or leave a program prior to completion. Factors considered include the role of governmental policies, the culture of poverty, race, housing, education, and stigma. Those in poverty in the community have expressed interest in self-sufficiency programs, however enrollment rates decrease considerably throughout the stages of the process, including inquiry, orientation, and the program itself. This study will ideally shed light on how organizations can better reach out to those suffering with poverty in the Dayton community and make sure to achieve high rates of program participation. The ultimate goal is to achieve a better understanding of the barriers that those in poverty face when trying to achieve self-sufficiency.

Participatory community action research in homeless shelters: New projects, findings, and future plans College of Arts and Sciences: Psychology Panel Discussion - Independent Research Goal 1: No Poverty Goal 2: Zero Hunger STUDENTS Fahad A M R Ameen, Hairela Ankaier, Amanda R Barry, Patrick Michael Broncato, Camryn N Buskey, Diego Antonio Buxeda, Zhuo Chen, Cara M Daley, Luis Enrique Feliciano, Marie Hermine Feyche, Katey M Gibbins, Brock Allen Grenci, Maria Nicole Guidobono, Mohammad A Hamzi, Zhaoyu Han, Henry S Hart, Becca Frances LeBouef, Saisai Li, Morgan L Liptak, Zihan Liu, Kuangze Lou, Hongyi Ma, Zhuonan Pan, Dana Lynn Pflugradt, Marie Cecilia Reddy, Claire E Rosengarten, Alicia Michelle Selvey, Yue Shen, Pengqing Sun, Arianna Alessandra Vasquez, Jiayu Wang, Caroline Rose Wattles, Torie C Weslow, Tre Alexander Whittaker, Alexander F Wolf, Bo Zhang ADVISORS Greg C Elvers, Roger N Reeb LOCATION, TIME Kennedy Union 331, 11:00-12:00 Homelessness is a ubiquitous and complex issue that affects all levels of society. This collaborative Participatory Community Action Research Project between Dr. Roger N. Reeb (Professor of Psychology, University of Dayton) and administrators at St. Vincent de Paul (Dayton, Ohio) implements Behavioral Activation at local homeless shelters as a way to address this problem within our community. Behavioral Activation (BA), a form of operant conditioning, refers to a therapeutic strategy that aims to increase overt behaviors by bringing a person into contact with positive response-contingent reinforcement. The project uses a service-learning pedagogy, with undergraduate and graduate students working alongside community members and faculty to contribute to the project in different ways. The BA project, which began in August of 2013, is implemented at both the Men’s Shelter and Women’s Shelter and has recruited well over 1,500 residents. Based on quantitative findings, shelter residents perceive BA sessions as meaningful, worthy of repeating, and enjoyable. Furthermore, quantitative findings indicate that, over time, shelter residents perceive BA as contributing to key psychosocial factors such as: hope, motivation for education or work, purpose or meaning in life, and social/emotional support. These findings were further supported by emergent themes in qualitative data (e.g., importance of student-resident relationships in supporting psychosocial improvements). In 2018, in collaboration with The Ohio State University Extension of Montgomery County, an urban farm was established on the grounds of the Men’s Shelter, which is located in a food desert. An M.A. Thesis was conducted and found that, similar to other BA sessions, the shelter residents perceived farming activities positively and that there was some evidence of therapeutic benefits for those who participated in farming sessions.

UN SUSTAINABLE DEVELOPMENT GOALS

in the contemporary age. I seek to explore these grounding questions as they relate to mothers who write and economically and socially privileged identities across difference. Various modes of motherhood and mediums of writing are considered. Lacey Spears, a popular “mommy blogger” convicted of killing her only son, and Adrienne Rich, celebrated feminist academic and poet, are put into conversation in order to examine radical embodiments of motherhood. I analyze Spears’ blog, which details her experience as she cares for she fabricated for her son in addition to Rich’s seminal work, Of Woman Born: Motherhood as Experience and Institution. With the testimony provided in these writings, I examine what it means to be a both a mother and a criminal, and a mother who transgresses expectations of femininity. Ultimately, this thesis is an attempt to understand the banal evil of structural poverty and the conditions it creates that allow brutality to be perpetuated by the least likely of sources: society’s ultimate care-giver, the mother.

Community Dietary Assessments (Assets) School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 302 01 Goal 2: Zero Hunger STUDENTS Abbie Hill, Emily Ann McDermott, Kim Alison Steinhebel ADVISORS Diana Cuy Castellanos LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Twin Towers is a low income community located in East Dayton about 1.5 miles from the University of Dayton’s campus. As there are multiple families facing food insecurity, there are a variety of programs that exist within the community aimed at expanding food access.The purpose of this research was to identify the current assets within the community that provide nutrition education and healthy food access in an attempt to combat the food insecurity prevalent in the Twin Towers neighborhood. The objectives of this community assessment were to recognize community assets that lead to increased engagement and empowerment of those residing in the Twin Towers neighborhood. In order to do this, we conducted a semi-structured interview with two key informants from the community and analyzed secondary sources regarding the two aforementioned topics. Findings include the presence of several community assets that can be expanded upon to improve food security of the Twin Towers neighborhood residents. Such assets include Miracle Makers, Mission of Mary programs, New Hope Church, and several others under the Food Access Resiliency Enterprise. Due to the information gained, we recommend working with the current community organizations to develop an asset based intervention to address issues around food knowledge, food access, and food program participation.

Addressing Food Insecurity through the use of Cooking Demonstrations at a Local Mobile Food Pantry School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 428 02 Goal 2: Zero Hunger STUDENTS Marie Frances Harla ADVISORS Diana Cuy Castellanos, Haozhou Pu LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Food insecurity and lack of cooking skills are issues that are prevalent in Dayton, Ohio. Many individuals and families visit food pantries and utilize other forms of nutrition assistance programs as a hunger safety net. With God’s Grace, a mobile food pantry, is providing monthly food distributions at East End Community Center in Dayton to those in need. In order to build cooking skills and nutrition education, a cooking demonstration was added to the monthly food distribution at East End. University of Dayton dietetic students run the cooking demonstration, and the purpose of this is to provide nutrition education and build cooking skills. The purpose of this study is to explore if the cooking demonstrations will increase utilization of the food that is distributed. Data will be collected from a survey after the participants have seen the cooking demonstration and tasted the sample. Recipes will also be distributed so that the participants can re-create the meal at home. The goal is to create healthy and easy recipes that participants will want to make on their own. The survey collects data on if they liked the recipe, why they would make it, and what are any barriers to making it. Survey results have been collected from September 2018 through February 2019, and they will be analyzed to explore how effective the cooking demonstration was to increasing people’s likelihood of utilizing the food provided by the mobile food pantry.

Identifying Antibiotic Producing Microbes College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Veronica K West ADVISORS Erica Marie Rinehart, Yvonne Y Sun

UN SUSTAINABLE DEVELOPMENT GOALS

LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Antibiotics were first discovered accidentally in 1928 and then purposefully synthesized to help combat bacterial infections. In the relatively short time since their discovery, many bacterial species have developed resistance mechanisms to these antibiotics. Due to the ability of pathogens to rapidly proliferate, beneficial mutations to increase their fitness in their environment have helped pathogens respond to antibiotics relatively quickly. The importance of discovering novel antibiotics to combat resistant strains is increasingly important. The Small World Initiative utilizes student researchers across the world to isolate new antibiotics to combat the intensifying antibiotic resistance dilemma. The goal of this research is to use bacteria isolated from soil to test their antibiotic producing abilities against a variety of previously known antibiotic resistant pathogens, termed ESKAPE pathogens. The gram-positive pathogen, Enterococcus faecium, specifically demonstrates antibiotic susceptibility to a few of the soil isolates. The susceptibility is confirmed by zones of inhibition which indicate that the isolate is producing antibiotics to which E. faecium is not yet resistant. The isolates that exhibit antimicrobial activity against the pathogens will be identified through a process of Gram staining, catalase testing, and other biochemical tests. The purpose of these tests is to identify new antibiotics that can be used to help combat antibiotic resistant pathogens.

Analyzing Bacterial Soil Isolates for New Antibiotic Production College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Meagan Nicole Lovin ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The last class of antibiotics to be discovered was in 1987, and no new antibiotics agents have been identified since. Bacteria have become increasingly resistant to our current stock of antibiotics and these strains have even been found to contain resistance to all known antibiotics. In the search for new antibiotics, the Tiny Earth Network has culminated labs all over the world to encourage students to join the search and learn about how to test and find new antibiotics. We collected soil samples from the University of Dayton and diluted them down to better separate out the individual bacterium. The selected bacteria are screened against various ESKAPE pathogens, specifically Acinetobacter baumannii and Staphylococcus aureus via their safe relatives, A. baylyi and S. epidermidis, respectively. This screening process showed six promising bacteria with significant zones of inhibition. Additional lab testing including Gram staining, catalase testing, triple sugar iron testing, MacConkey agar, motility identification, mannitol salt agar testing, chia seed testing, and finally PCR, extraction, and DNA sequencing will be utilized to determine the identity of the bacteria we discover. This research brings hope to the discovery of a new antibiotic that can be used on the pharmaceutical counter.

Testing UD Soil Isolates for Antimicrobial Activity College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Elizabeth M Collins ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Antibiotics are important in both the prevention and treatment of bacterial infections. However, there has been an increase in antibiotic resistance. Antibiotic resistance is when a microbe counters the effects of the antibiotic, and continues to reproduce. As the spread of antibiotic-resistant infections grow, the bigger the threat to public and global health. The Small World Initiative and the Tiny Earth Networkâ&#x20AC;&#x2122;s mission is to support student research in antibiotic discovery by isolation of unknown bacteria from soil. Over the past semester, I have been conducting research with the aim to find microbes that produce antimicrobial effects on known ESKAPE pathogens from soil collected outside Roesch Library. A soil sample was collected from the gazebo next to Roesch Library. Bacteria colonies were plated on TSA and TH plates. Eleven colonies from the TSA plate and ten colonies from the TH plate were selected to be tested against the known pathogens of Enterococcus faecium and Klebsiella pneumoniae. These pathogens cause similar infections and are transmitted the same way by direct contact. However, Enterococcus faecium is a gram positive bacterium and Klebsiella pneumoniae is a gram negative bacterium. By choosing two different types of bacterium the goal is to discover if there is a difference in antimicrobial activity based on the type of pathogen. Antimicrobial activity is determined by the presence of a zone of inhibition. For the bacteria that show antimicrobial activity, a series of tests, which include gram staining and biochemical testing, were performed to identify the bacterial isolates. Future implications of this research could help create new antibiotics to fight against human pathogens and further improve the public health of the community.

UN SUSTAINABLE DEVELOPMENT GOALS

The Dirt on Antibiotics at the University of Dayton College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Michelle Lynn Borchers ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Antibiotics have become a problem as their overuse has led to pathogens resisting the effect of antibiotics. This is an important health matter as once effective antibiotics no longer work to cure some illnesses. The Small World Initiative and the Tiny Earth Network function to discover potential antibiotics in nature by isolating bacteria from soil samples in the environment and testing them against ESKAPE pathogens. The goal of this research is to help support the Small World Initiative by testing soil for the presence of naturally occurring antibiotics on the University of Dayton’s campus. A sample of soil was collected from a backyard on campus grounds and tested against ESKAPE pathogen safe relatives Enterococcus faecium and Enterococcus raffinosus. Antibacterial effects can be quantified by measuring the zones of inhibition on the agar plates. Lab techniques such as aseptic technique, serial dilution, master plates, and spread plates were used to isolate the pure bacterial colonies that showed antibacterial effects on the pathogens. Gram staining and biochemical testing were performed to try to identify the bacterial isolates. The biochemical tests include: catalase, hemolysis, triple sugar iron, mannitol salt agar, MacConkey agar, citrate, gelatinase, and motility. The antibiotic producing chemicals of the pure colonies were then extracted and tested with eukaryotic cells. The findings will help contribute to the mission of the Small World Initiative and the Tiny Earth Network.

Discovering Antibiotics from UD’s Soil College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Jackie Nicole Petrichevich ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The discovery of antibiotics has helped humans survive many diseases that were once deadly. But with the overuse of antibiotics in the medical field, some “superbugs” have evolved resistance to multiple antibiotics we utilize. The Tiny Earth Network and Small World Initiative have started a coalition of undergraduate students to help discover new antibiotics from different soils around the world. Over the past semester, I have been doing research to find microbes from soil outside of the Adele Center that has antimicrobial effects on known pathogens. This work is important because it could lead to the discovery of new antibiotics that can kill pathogens affecting humans. The bacteria that was collected was tested against the pathogens Acinetobacter baylyi and Enterococcus raffinosus to determine how efficient the antimicrobial properties were. Gram stains and biochemical tests were then used to help identify and characterize the bacteria we were working with. From there, I isolated antibiotic compounds and tested them against pathogens and eukaryotic cells. Overall, this work helps to support the Tiny Earth Network and Small World Initiative and will, hopefully, help to resolve the antibiotic crisis we are currently having.

Using University of Dayton Soil to Isolate Antibiotic Producing Bacteria College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Ali Nicole Wiggins ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The overuse of antibiotics has created pathogens that have become resistant to the antibiotics effects. This is becoming a large issue because if the pathogens are resistant to the antibiotics then the antibiotics will no longer be able to cure certain illnesses. The Tiny Earth Network and Small World Initiative have created are partnering with undergraduate students in order to try to discover new antibiotics to combat this issue, using different soil samples from around the world. The goal of this research is to test University of Dayton soil for bacteria that produce antibiotics to help support the Tiny Earth Network and Small World Initiative. The soil sample was diluted down in order to isolate bacterium and then the bacteria colonies were plated on TSA and TH plates. Ten bacteria colonies were selected from each plate and tested against the known ESKAPE pathogens, Enterococcus faecium and Pseudomonas aeruginosa by using their safe relatives Enterococcus raffinosus and Pseudomonas putida. Two of the isolated bacteria showed zones of inhibition on both of the safe relative plates. The two bacteria colonies that had zones of inhibition were tested further using gram staining, catalase testing, hemolysis, triple sugar iron test, mannitol salt agar testing, MacConkey agar, citrate, gelatinase, motility identification. Then the bacteria was classified and then tested against Eukaryotic cells in order to find a safe antibiotic. This research helps contribute to the mission of the Tiny Earth Network and the Small World Initiative, in hopes of resolving the antibiotic crisis.

Antibiotic Producing Bacteria in Soil Samples at the University of Dayton College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Erin Elise Pellot ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Within recent years there has been a rise in the number of antibiotic resistant bacterial strains. These resistant strains have no known treatments and thus pose a threat to society. Bacterial strains form resistance by evolving past the mechanisms behind a given antibiotic. With bacteriaâ&#x20AC;&#x2122;s unrelenting ability to evolve and adapt there is an ever present need for new antibiotics. To relieve this need, the Tiny World Initiative was formed to provide students the chance to conduct antibiotic research in the classroom setting. For this in class research experience, an on-campus soil sample was collected and analyzed for possible antibiotic producing microbes. After cultivating and selecting bacterial colonies, samples were tested against two pathogen safe relatives of the ESKAPE pathogens. ESKAPE is an acronym to describe the six most antibiotic resistant opportunistic pathogens which pose a threat to society. The ESKAPE relatives tested against in this experiment were Pseudomonas putida and Staphylococcus epidermidis. After finding seven antibiotic producing colonies the samples were put through multiple classification tests which include a gram stain, catalase test, hemolysis, triple sugar iron, mannitol salt agar, MacConky agar, citrate, gelatinase and a motility test. After classifying the samples they were tested against Eukaryotic cells in the hopes of finding a safe antibiotic treatment.

Role of Hippo and Ecdysone Receptor Signaling in regulation of dronc. College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Karishma Sanjay Gangwani ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The Hippo pathway is an evolutionarily conserved pathway that regulates organ size and tissue homeostasis in Drosophila and mammals. The pathway functions by regulating the nuclear availability of transcriptional cofactor Yorkie (Yki), mammalian YAP, which is regulated by the activity of a core kinase cascade comprising the serine threonine kinases Hippo (Hpo) and Warts (Wts) and their accessory proteins. Yki binds with transcription factors like Scalloped (Sd) or Homothorax (Hth) to regulate target genes involved in cell proliferation and survival. Downregulation of the Hpo pathway causes increased cell proliferation and overgrowth, whereas hyperactivation of this pathway leads to cell death due to activation of caspases. Caspase proteins are cysteine aspartic proteases which play essential roles in cellular signaling and development via apoptosis. We showed that the initiator caspase dronc (mammalian Caspase 9) is a transcriptional target of Yki. We found that loss of Hippo signaling leads to downregulation of dronc expression, whereas downregulation of Sd resulted in derepression of dronc expression. We also found that known binding partners of Sd like E2F and Tgi are also involved in regulating dronc expression. Earlier studies have shown that dronc expression is regulated by the Ecdysone receptor (EcR) signaling pathway and mapped a EcR regulatory element on dronc promoter. We found that depletion of EcR or its corepressors like Smrter caused de-repression of dronc expression. Overexpression of Taiman (Tai) a binding partner of EcR and Yki also derepressed dronc expression. We hypothesize that dronc expression is regulated by the Hippo and EcR signaling pathways. Here, we present our work on the regulation of dronc by the Hippo and EcR signaling pathways, and its implications on development.

pathways in the TME. We established a new TME model by creating FLP-out clones of oncogenic forms of Yki or RasV12 in polarity deficient (scribble mutant) cells marked by GFP surrounded by normal cells. These mosaic clones allow us to test changes in intercellular and signaling interactions within the tumor, surrounding its microenvironment and in distant normal cells. We studied the activity of TLR, TNF and JNK pathway using immunohistochemistry. We found that Drosophila IκB Cactus (TLR component) and activated form of JNK (p-JNK) were induced in the tumor cells whereas levels of Drosophila TNF ligand, Eiger were unaffected in both the tumor and the surrounding normal cells. We hypothesized that crosstalk between these key pathways in the TME promotes tumor survival and progression. The genetic epistasis experiments between JNK and TNF revealed that downregulation of the TNF receptors in the tumor does not affect the metastatic abilities of the tumor cells. However, similar experiments between JNK and TLR showed decrease in invasiveness of tumor cells likely due to downregulation of Cactus in the tumor cells. We are currently testing if TLR, TNF and JNK pathways genetically regulate each other or independently affect the TME to control tumor growth. Our research will help to unravel the correlation between inflammatory pathways and tumor progression in an in vivo model.

Inspecting the role for the trans-regulatory landscape to the origin, diversification, and loss of a sexually dimorphic fruit fly pigmentation trait College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Jesse Taylor Hughes ADVISORS Tom M Williams LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 A major goal for evolutionary-developmental biology research is to identify the genetic changes underlying the origins, diversification, and loss of morphological traits. Such traits are built by the spatial and temporal regulation of gene expression, and thus the evolution of gene expression is often involved in their evolutionary histories. Gene expression is under the control of a network of transcription factors (translandscape) that ultimately impinge on the cis-regulatory elements (CREs) of differentiation genes whose encoded proteins produce particular traits. Transcription factor genes are often highly pleiotropic, as they can regulate the expression of multiple genes for multiple traits. Thus, it seems reasonable to expect that evolutionary changes in gene expression more frequently occurred by mutations altering the CREs for differentiation genes than changes to the trans-landscape. Our research aims to test whether this expectation for a conserved translandscape applies to the origin, diversification, and loss of a well-studied fruit fly pigmentation trait in the Sophophora subgenus. The origin of a male-specific pattern of abdominal tergite pigmentation involved the gain of CREs controlling the expressions of pigmentation enzyme genes responsive to the prevailing trans-landscape of body plan patterning and sexual dimorphism transcription factors. Here, we share our results from tests of these CREs in transgenic hosts that represent the ancestral sexually monomorphic trait, diverse forms of the derived dimorphic trait, and a secondary loss of the dimorphic trait. The outcomes from these tests will reveal the extent to which this particular trans-landscape has remained conserved while the pigmentation phenotype has widely evolved.

Resolving the Molecular Mechanisms by Which DNA Mutations Alter the Function of a Genetic Switch College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Michael Weinstein ADVISORS Tom M Williams LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Animal genomes likely possesses anywhere from tens of thousands to more than a million mutations that are genetic baggage from DNA replication mistakes or “mutations” that occurred in the past. Each mutation can either improve, reduce, or have no effect on fitness. Moreover, the effects of such mutations can depend on the presence or absence of other mutations, so called epistatic interactions. A goal of evolutionary-developmental biology research is to identify the mutations responsible for the evolution of form and function, and to understand the molecular mechanisms of their effects. This goal remains out of reach, as the effects of mutations and epistatic interactions are difficult to predict without knowing the function of the DNA sequence they reside in. This difficulty is heightened for mutations occurring in cis-regulatory element sequences that act as switches to control gene transcription. We are using a fruit fly model to test hypotheses about the molecular mechanisms by which mutations alter a genetic switch’s activity, and whether these function-altering mutations are subjected to the tyranny of epistatic interactions. Specifically, we are investigating the Drosophila melanogaster dimorphic element that is a transcription-regulating switch for the bric-à-brac genes. Three mutations in the dimorphic element were identified that individually alter the level of bric-à-brac transcription. The presence or absence of epistatic interactions will be determined by measuring the activity of dimorphic elements from related species that have been engineered to possess the Drosophila melanogaster mutations. I will also test the hypothesis that these mutations impart their effects by creating or destroying binding sites for proteins known as transcription factors. The results will provide a sorely needed example where an understanding of molecular mechanisms bridges the gap between a cis-regulatory element’s DNA sequence and it’s in vivo function.

Role of Hippo Signaling in Amyotrophic Lateral Sclerosis (ALS) disease using Drosophila eye model College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Neha Gogia, Abijeet Singh Mehta, Ankita Sarkar ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Amyotrophic lateral sclerosis (ALS), or Lou Gehrigâ&#x20AC;&#x2122;s Disease, is a late-onset neurodegenerative disorder characterized by loss of cortical and spinal motor neurons with no known cure to-date. Mutations in genes including human Fused in Sarcoma (h-FUS), (caz in Drosophila), is a DNA/RNA binding protein, plays a crucial role in regulating nucleocytoplasmic RNA transport, alternative splicing and has known to be associated with causing ALS. It has been shown earlier that targeted misexpression of h-FUS or its mutants R518K and R521C (using GAL4/ UAS system), in Drosophila melanogaster (a.k.a fruit fly) eye, causes accumulation of ubiquitinated proteins which enhances ALS mediated neurodegeneration. In order to 1. understand this process better, 2. search for genetic modifier of ALS and 3. to elucidate the mechanism of action by which FUS mediates neurodegeneration, we used this fruit fly eye model of ALS (as genetic machinery is conserved from fruit flies to humans) and, checked the effect of modulating the levels of Hippo (growth regulatory pathway, highly conserved) and c-Jun N-terminal Kinase (JNK) signaling in h-FUS or its mutants R518K, R521C background and checked for their resultant phenotypes in 1. larval eye-antennal imaginal discs and 2. adult fly eyes. Results from our studies confirms that, Hippo (hpo), is a newly identified genetic modifier of ALS mediated neurodegeneration, and that activation of Hippo or JNK pathway in FUS background worsens FUS mediated neurodegeneration while their in-activation significantly rescues FUS mediated neurodegeneration in fly eye. The results were confirmed by checking 1. cell death (TUNEL assay), 2. axonal targeting (functionality of photoreceptor neurons) from the retina to the brain, 3. Q-PCR, Western blot analysis, and 4. by checking how downstream targets of Hippo and JNK pathway gets regulated in these backgrounds. Our data presents a model that upregulation of FUS or its mutants, results in activation of Hippo pathway, which further activates c-Jun N-terminal Kinase (JNK) signaling and causes neurodegeneration/ photoreceptor neuronal cell death which ultimately causes ALS. This study helps in understanding the molecular genetic mechanism behind ALS associated h-FUS mediated neurodegeneration and finding effective, reliable future therapeutic targets that can modify the neurodegenerative behavior of ALS.

Effect of a Novel Zinc Porphyrin against Pseudomonas aeruginosa Biofilms Attached to Different Substrata College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Jessica Elizabeth Geyer ADVISORS Karolyn M Hansen, Jayne B Robinson LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Clearance of surface attached biofilms produced by bacterial colonization remains a relevant challenge in both industrial, and the biomedical communities. The difficult eradication of these biofilms rests in that bacteria produce an extracellular matrix that encases the cells; this acts as a scaffold for growth and imparts a form of protection. The matrix promotes resistance to treatment by physically blocking the passage of antibiotics to the bacterial cells. Work in our lab has produced a patented zinc porphyrin (ZnPor) which has the ability to disrupt attached biofilms on polyethylene by interacting with the base pairs of extracellular DNA found in the matrix. Biofilms disturbed by this porphyrin have been shown to become highly sensitive to antibiotics that previously had little to no effect. The objective of this project was to analyze the effect of ZnPor on removing biofilms attached to different surfaces. These data will set the stage for effective treatment of biofilms attached on a wide range of substrata: polyethylene (used in catheters), titanium (used in biomedical implants), hydroxyapatite (similar to bone) and borosilicate glass (control). This will be done by forming substrata into small coupons that will be placed into a CDC approved bioreactor. Pseudomonas aeruginosa will be inoculated into the bioreactor, and biofilms formed by 16~ 18 hours will then be treated by ZnPor followed by various antibiotics. The biofilms will be imaged with a LIVE/DEAD stain and analyzed by confocal laser scanning microscopy.The significance of our novel approach to antimicrobial management is that, unlike other protocols involving biofilm eradication, our strategy addresses the issue of resistance. The ability to disrupt the inherent matrix structure of biofilms and make cells accessible to antibiotic treatment promotes little resistance. Additionally, it decreases bacterial success in colonization of biomaterials and associated mortality rates in immunocompromised individuals.

The potential role of mir-277 in Alzheimer’s disease College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Prajakta D Deshpande, Brent O Mcginty ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 As the most common progressive neurodegenerative disorder, Alzheimer’s disease (AD) has been predominantly found in people 65 years of age or older. AD is associated with a gradual decline in cognitive impairment and memory as well as effects on behavior and decision making. AD is also responsible for the most dementia cases in elderly people. As per the Alzheimer’s Association facts, over 5 million Americans were affected by AD in 2018 whereas the number is predicted to rise to approximately 14 million in 2050. One of the causes of AD is mis-cleavage of the transmembrane protein called amyloid precursor protein (APP) by the enzymes β-secretase and γ-secretase, resulting in accumulation of amyloid beta-42 polypeptide (Aβ42). These amyloid beta peptides aggregate into hydrophobic plaques in the extracellular region in the brain, altering the cellular pathways and resulting in neuronal death. In this study, we have used Drosophila as a model system and misexpressed the human Aβ42 in the photoreceptors of the Drosophila eye. The misexpression of the Aβ42 in the Drosophila eye triggers the neuronal cell death resulting in a glassy reduced eye phenotype. This study focusses on how microRNA mir-277 regulates the Aβ42 mediated neurodegeneration. MicroRNA regulate the gene expression post-transcriptionally and repress the protein formation by sequence-specific degradation of target mRNA. Earlier studies have shown the association of microRNA in AD and the role of mir-277 in AD is not clear. This study adds to our understanding of the role mir-277 may play in Aβ42 mediated neurodegeneration and its potential role as a biomarker for AD.

Role of Lunasin in Alzheimer’s disease College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Steven Gerard Borchers, Prajakta D Deshpande, Neha Gogia ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alzheimer’s disease (AD), a common form of dementia and age related progressive neurodegenerative disorder, manifests as memory loss and reduced cognitive ability. One of the hallmarks of AD is the formation of the Amyloid-beta 42 (hereafter Aβ42) plaques, which triggers oxidative stress due to aberrant signaling and finally results in the death of neurons. However, the exact mechanism causing cell death is still not well understood. We misexpressed high levels of human Aβ42 protein in the developing fly retina, which mimics AD-like neuropathology. Recently, we found that a plant protein Lunasin can ameliorate Aβ42 mediated neurodegeneration in the eye by blocking c-Jun N-terminal kinase (JNK) signaling pathway. It is known that Immune deficiency (IMD) pathway, Nuclear factor-κB (NF-κB) signaling pathway, Toll receptor pathway and JNK pathway crosstalk with each other in neurodegeneration. Here we test the role of IMD and NF-κB pathway in Aβ42 mediated neurodegeneration. Loss of function of Relish (Rel), a member of and NF-κB and its downstream gene- Diptericin rescues the small glazy eye phenotype. Our working model is that Lunasin might down-regulate JNK signalling pathway which in turn downregulates IMD pathway to ameliorate Aβ42 mediated neurodegeneration.

Deciphering Novel Calcium-signaling Circuits Implicated in the Neurobiology of ADHD College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Aikaterini Britzolaki, Claire C Cronin, Patrick Robert Flaherty, Benjamin Klocke, Joey Edward Saurine ADVISORS Pothitos Pitychoutis LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Attention-deficit/hyperactivity disorder (ADHD) is a highly-heritable heterogeneous neurodevelopmental disorder characterized by inattention and/or hyperactivity-impulsivity. ADHD affects 5% of children and 2.5% of adults in the general population with higher prevalence in males than females. It is believed that ADHD is caused by alterations in several neuronal circuits. In the quest of determining the regulators that lead to such neuronal alterations, intraneuronal calcium signaling has been vastly studied. Indeed, intracellular calcium signaling is crucial for the fate of the neurons and calcium dyshomeostasis has been associated with a variety of debilitating neuropsychiatric disorders. Our group focuses on deciphering the regulatory mechanisms coupled to calcium-handling in the central nervous system (CNS). Comprehensive studies have revealed that calcium distribution in the cell is majorly regulated by the endoplasmic reticulum (ER), and hence the latter’s critical role in maintaining neuronal calcium homeostasis. We have recently identified a novel calcium-regulating protein expressed in the brain and

we are demonstrating for the first time, its implication in the neurobiology of ADHD. In the context of this presentation we will demonstrate overwhelming molecular, cellular and behavioral data to support the pivotal role of this novel calcium-regulating protein in the neurobiology of ADHD.

Role of Relish/NFkB Apoptosis Pathway in Amyloid-beta 42 mediated neurodegeneration in Alzheimer’s disease College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Steven Gerard Borchers, Prajakta D Deshpande, Neha Gogia ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alzheimer’s disease (AD), is a neurodegenerative disease which affects mental functions of the patients. This disorder progresses with age and does not have a cure to-date. One of the reasons for the manifestation of AD is the accumulation of amyloid-beta-42 (Aβ42) proteins. In our study, we have used Drosophila as our model organism (as 75% of the genetic machinery is conserved between flies and humans), and have developed a model where when human Aβ42 is misexpressed in the differentiating eye, it triggers cell death in retinal neurons of the eye. We have identified that Lunasin (a soy-based anti-inflammatory protein), can block Aβ42 mediated cell death and thus wanted to test whether NFkB pathway (anti-inflammatory pathway, lead to translation of apoptotic proteins of jun-N Terminal Kinase, JNK pathway), helps lunasin blocking cell death. In order to test this, we developed transgenic flies which can produce human Aβ42 and Aβ42+Lunasin in Drosophila eye and checked the effect of modulating NFkB pathway in this background. Our hypothesis states that manipulating the levels of Relish (component of the Imd-NFkB pathway), could lead to activity variation in JNK pathway in Aβ42+Lunasin flies. To test our hypothesis, we used GAL4/UAS system genetic technique and misexpressed Relish and RelishRNAi in human Aβ42 and Aβ42+Lunasin background and checked for the resultant phenotypes in (1) larval eye discs and (2) adults. Our data shows that downregulation of Relish interferes with Lunasin’s ability to rescue Aβ42 phenotypes and thus leads to eye suppression phenotypes, which suggests that Imd-NFkB pathway plays a positive role in Lunasin’s ability to mitigate the neuronal cell death cause by the accumulation of Aβ42 plaques. These studies have significant bearing on the use of NFkB members as biomarkers or druggable targets and generate new insights into the mechanism by which Aβ42 mediated neurodegeneration cell death can be blocked in future.

Investigation of the role of OPA1 and Drp1 gene mutations in amyloid-beta 42 mediated neurodegeneration in Alzheimer’s Disease College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Elizabeth Ann Borchers, Neha Gogia, Lydia Christine Payton ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alzheimer’s Disease (AD), is a progressive neurodegenerative disorder with no known cure to-date. This disease is caused by extra-cellular accumulation of amyloid-beta 42 (Aβ42) plaques, which results in neuronal cell death. As the genetic machinery is conserved between fruit flies and humans, in this study, we have used Drosophila melanogaster (a.k.a fruit fly) as our model organism and Drosophila eye as our model organ. We have developed a transgenic Drosophila model of AD where using GAL4/UAS system, the human Aβ42 peptides are misexpressed specifically in the differentiating photoreceptor neurons of the fly eye, resulting in death of these neurons without affecting the reproductive ability and life span of the flies. One of the hallmarks of AD is the generation of reactive oxygen species (ROS) from mitochondria, which triggers neuronal cell death. We hypothesize that 1. OPA1 (Mitochondrial Dynamin Like GTPase), and 2. Drp1 (dynamin related protein-1), (conserved between flies and humans), regulate mitochondrial fusion and fission respectively, are involved in regulating Aβ42 mediated neurodegeneration. A fine balance between mitochondrial fission and fusion events is essential for normal mitochondrial and cellular function and it has been known that mutations of OPA1 (an early stop signal) produce small unstable mitochondrial proteins, which increase ROS levels in the neurons. There is a strong correlation between increased ROS levels and mitochondrial fragmentation with neuronal death. Thus, we investigate the role of both OPA1 and Drp1 in Aβ42 mediated neurodegeneration. Results from our preliminary data show that up-regulation of OPA1 in Aβ42 background, significantly rescued Aβ42 mediated neurodegeneration only in female flies, and down-regulating OPA1 rescued Aβ42 neurodegeneration only in male flies. In contrast, down-regulating Drp1, rescued Aβ42 mediated neurodegeneration only in female flies, while up-regulation of Drp1 did not produce any rescues. Further studies on how mitochondrial maternal inheritance takes place will help us better understand these results.

Global and Gene Specific Regulation in Response to Physiological State in Freeze Tolerant Anuran Dryophytes chrysoscelis College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Elizabeth Claire Sinnathamby ADVISORS Carissa M Krane LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Cope’s Gray Treefrog, Dryophytes chrysoscelis, seasonally tolerates freezing. During this process, it is subject to cellular stress from factors such as metabolic starvation, DNA damage, toxin accumulation (from cellular metabolism), and the risk of protein misfolding. Preliminary transcriptome data indicates that many mRNA transcripts vary in relative abundance within hepatocytes of D. chrysoscelis during discrete periods of warm acclimation, cold acclimation, freezing, and thawing . Physiological changes that occur in this frog are likely the result of epigenetic regulation—an alteration in gene expression that does not influence DNA sequence. This modification in gene expression can be observed by the subsequent change in relative abundance of mRNA transcripts. This thesis investigates the relative abundance of several mRNA transcripts for (1) methyltransferase genes that mediate some epigenetic regulation by transferring methyl groups (global regulation) and (2) genes that mediate stress responses contributing to freeze tolerance (local regulation). All of the genes selected are orthologous counterparts to those found in humans. We hypothesize that methyltransferases important to the freezing process will be differentially regulated (either up-regulated or down regulated) compared to the warm condition, whereas stress genes that enhance the survivability of the frogs during freezing will be up-regulated and those that are metabolically costly will be down-regulated. These results demonstrate trends in mRNA expression within four biological groups (warm acclimated, cold acclimated, frozen, and freshly thawed) that may be relevant to the freezing process. mRNA was isolated from livers of frogs within the four biological groups at the time they were sacrificed. cDNA was created and relative abundance was identified using RTqPCR techniques. Results were analyzed using ΔΔCt logarithm to calculate fold change. Deeper understanding of physiological processes that either contribute to or are metabolically costly to freeze tolerance may have future applications in human tissue banking and cryopreservation of organs for transplants.

Cortisol Regulation of Aquaglyceroporin HC-3 Protein Expression in Erythrocytes from the Freeze Tolerant Tree Frog Dryophytes chrysoscelis College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being Goal 15: Life On Land STUDENTS Maria Pasqualina LaBello ADVISORS Carissa M Krane LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Dryophytes chrysoscelis, commonly known as Cope’s gray treefrog, is a freeze tolerant anuran that freezes up to 65% of extracellular fluid during winter to survive. Glycerol is presumably used as a cryoprotectant during a period of cold-acclimation to protect cells from permanent damage due to hypoosmotic stress upon freezing and thawing. The transmembrane movement of glycerol and water is likely mediated through aquaglyceroporin (GLP) 3 ortholog HC-3 in the nucleated erythrocytes (RBCs) of D. chrysoscelis. This thesis analyzes the mechanisms in which D. chrysoscelis prepares for cold-acclimation and glycerol synthesis. Cortisol, a neuroendocrine steroid hormone, is a stress hormone previously shown to respond to osmolarity challenges and regulate aquaporins in teleost fish; however, the role of cortisol in regulating anuran HC-3 protein expression and membrane subcellular localization is yet to be known, and the implications for mediating anticipatory glycerol synthesis and freeze tolerance remain to be determined. We hypothesize that cortisol exposure contributes to enhanced HC-3 protein expression and subcellular localization in the membrane of RBCs from D. chrysoscelis. RBCs were cultured in vitro using complete cell culture media (CCCM) and cortisol for 0, 2, 4, 6, and 8 hours at two separate concentrations, 1.0 μg/ml and 0.1 μg/ml. Another group of RBCs was incubated with CCCM for 24 hours before the 0, 4, and 8-hour incubation with cortisol concentrations of 1.0 μg/ml and 0.1 μg/ml. Western blotting was utilized for quantifying HC-3 protein expression and immunocytochemistry was used to visualize the subcellular localization of the HC-3 protein from the cultured RBCs. The findings gleaned from this thesis provide insight to support human tissue cryoprotection and transplantation.

The Presentation of Stigmatized Health Issues in Network Television Content College of Arts and Sciences: Communication Poster - Course Project, 201880 CMM 390 P1 Goal 3: Good Health and Well-Being STUDENTS Franchesca Robin Hackworth ADVISORS Angeline L Sangalang LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The present investigation attempts to provide a more comprehensive investigation of stigma in media by exploring representations of two important stigmatized health contexts (mental illness and HIV/AIDs) in a representative sample of television programming. The study has three objectives: 1) identify the program types more likely to contain information about these stigmatizing health conditions, 2) explore differences in stigmatizing information present in each program type, and 3) explore similarities and differences between contexts. Findings from the investigation have the potential to provide insights for media literacy initiatives (i.e., identifying particularly problematic exposure points) and stigma reduction messaging (i.e., identifying specific cues that need to be corrected or dispelled through campaign or treatment efficacy messages). A television sample of 672 total hours of content was coded for mentions of HIV/AIDs and mental illness. Discussions of mental illness were about 10x more prominent than those of HIV/AIDs and across a diverse range of programming types, while HIV/AIDs mentions were limited to news, commercials, and talk shows. Mental illness content was often associated with the advertisement of a drug. Mental health has the potential to be more stigmatized because of its frequent presence. Local news contained the most content for both health issues (39% HIV/AIDs and 35% mental illness), followed by commercials (29%) and drama (19%) programming for mental illness and talk shows (35%) and commercials (17%) for HIV/AIDs. It may be possible that different production techniques and demands for different programs facilitate portrayals of health issues in different ways. An investigation such as this one allows for comparison between program type within the same time frame, an analysis that is missing from the present landscape of scholarship. We hope to provide directions for stigma reduction messages and areas of attention for media scholars.

A Campaign to Motivate College-Aged, Catholic Women to Get Tested for STIs at the University of Dayton College of Arts and Sciences: Communication Poster - Course Project, 201910 COM 543 02 Goal 3: Good Health and Well-Being STUDENTS Emma Rutledge Venetis ADVISORS Angeline L Sangalang LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In 2017, women ages 20-24 had the highest rate of chlamydia cases among any age group for men or women. Additionally, Catholic women are more likely to have “hooked up” while in college than women with no religious affiliation. Due to the already high rate of STIs among young adults, the frequency of sexual activity of college students and the increased frequency for Catholic women, the fact that many STIs are asymptomatic, and the health risks that untreated STIs can cause, testing for, diagnosing, and treating STIs is critical to stop the increasing spread of these infections. According to results from the American College Health Association’s [ACHA] National College Health Assessment Survey conducted in 2018, 98% of college students say that they have not dealt with an STI in the last 12 months. In fact, only 1.8% of college students say that they have been diagnosed or treated for chlamydia, despite the extremely high rates of infection among their age group. This does not suggest that college students are not at risk for STIs, especially considering that less than half of college students who engaged in vaginal intercourse in the past 30 days reported using a condom or other protective barrier. Instead, it suggests that this population is not being tested for STIs at the frequency needed to diagnose and treat STIs. The present investigation surveyed college-aged women to better understand the attitudes, norms, and self-efficacy of Catholic, female UD students surrounding the health behavior of STI testing. This research will propose a campaign and provide specific communication strategies to motivate female Catholic UD students to get tested for STIs at the UD Health Center.

A kayak paddle assistive device, the Paddle Pro, was designed that would be able to help those with minimal hand and core strength be able to paddle. This device can also be used as a training mechanism to help young children learn how to paddle a kayak, especially if it is their first-time kayaking. The Paddle Pro is a t-stand that attaches to the base of a kayak. It has a suction cup base with PVC pipe attachments that will provide support to the paddle. The ball and socket joint is connected to a “steering wheel” style attachment which provides a wide range of motion in order to create the right form for paddling a kayak. In addition, the group added Velcro hand straps that helped provide support to children with minimal hand strength.

Medical Imaging to Patient Specific Additively Manufactured Implant School of Engineering: Electrical and Computer Engineering Poster - Course Project, 201853 EXP 305 P1 Goal 3: Good Health and Well-Being STUDENTS Monica M Yeager ADVISORS Amy T Neidhard-Doll LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 As of 2018, there are only standard sized, cast molded hips available to patients requiring hip implants. However, everyone has a unique body, so a cast molded hip implant will fit people differently. Personalized additively manufactured, or 3D-printed, implants created from a patient’s own computerized tomography (CT) or magnetic resonance imaging (MRI) images may provide numerous benefits. A main benefit would be that the implant would provide a personalized fit for the patient, as it would be made from scans of his or her own body. With a personalized fit, there would be reduced surgery and recovery time. For people with a physiological abnormality, a customized solution may be printed for reconstructive surgery. Another benefit would be for surgeons who could 3D print their patient’s bone for pre-surgical planning, such as planning screw placements. As the baby boomer population ages, the commercial market for 3D-printed joint replacements is expected to soar over the next decade. The goal of the research conducted here is to demonstrate a prototype process for patient specific, additively manufactured hip implants made from Digital Imaging and Communications (DICOM) images of human femur bone, leading to additional research on imaging of trabecular bone for biomimetic lattice development.

(R2U-Net), applied on the sequence of CT scan images. These computational methods can replace the conventional methods, and overcome their limitations of time delays, the absence of a doctor, and unavailability of instruments. A large number of high-resolution CT images make numbers of slices, and some of the lesion features are not obvious, which leads the heavy work for doctors. The advantage of 3D imaging over 2D imaging is achieved by processing the higher dimensional data. 3D medical imaging can extract more features and surrounding information; that is helpful for the diagnosis. The output can be further helpful to recognize cancerous tumor with its volume inside the lungs. The proposed work will provide more opportunities to explore different modalities of medical imaging.

Skin Lesion Segmentation and Classification using Deep Learning and Handcrafted Features School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 3: Good Health and Well-Being Goal 15: Life On Land STUDENTS Redha Ali ADVISORS Russell C Hardie LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Skin cancer is one of cancer type that has a significant impact on society in the United States and across the world. Recently, several Computer-Aided Diagnosis (CAD) system papers have been presented. However, there is still an opportunity for further development in the accuracy of its diagnosis. In this research, we propose an algorithm for skin cancer segmentation and classification at a more treatable stage. Our current approach is computationally efficient and combines information from both deep learning and handcrafted features. Our system creates robust hybrid features that have a stronger discrimination ability than single method features. These features are used as inputs to a decision-making model that is based on a Support Vector Machine (SVM) classifier. Our results evaluated online validation and test databases. Our score was 0.841 on the validation dataset and 0.701 on the test dataset for the classification task. We participated in the ISIC Challenge 2018, being ranked 59th for disease classification and 85th for skin lesion segmentation out of 141 methods listed on the competition leaderboard. These statistics do not include the rankings of the groups who did not qualify for the leaderboard. Also, it is important to note that many of the successful methods that were ranked highly used additional external data for training. The ISIC 2018 competition does not provide the external data that they used. We only utilized the competition which provided data for training.

Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Pedestrians face dangers during their daily commutes through urban and rural environments. When considering fast-moving cars and bicycles and even other civilians, vigilance is imperative to maintaining pedestrian safety. The Computer Vision Pedestrian Awareness System is a wearable device that seeks to increase pedestrian rear-awareness to potential dangers by alerting users to dangerous events before the events occur.

Disordered Eating at the University of Dayton College of Arts and Sciences: English Poster - Course Project, 201910 ENG 373 H1 Goal 3: Good Health and Well-Being Goal 4: Quality Education STUDENTS Caroline Anne Calhoun, Brian Christopher Hughes, Dana Pamela Kieft ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Eating disorders, disordered eating, and concerning eating habits are common on college campuses among both men and women. Certain demographics are more likely to develop eating disorders or disordered eating habits than others; however, the issue is widespread and impacts many people. The increased stress, decreased supervision, and the need to develop new eating patterns in college create an environment where eating disorders or other disordered eating habits can be easily developed or go unnoticed. For this project, we researched University of Daytonâ&#x20AC;&#x2122;s (UD) resources available for students who may have disordered eating or diagnosed eating disorders. When students are facing issues at UD, they can talk to a counselor at the counselling center, go to the health center, womenâ&#x20AC;&#x2122;s center, or even

UN SUSTAINABLE DEVELOPMENT GOALS

speak to an RA for example. However, we found few resources available specifically for eating disorders. We also analyzed other universities’ resources and materials, which showed that many other schools similar to UD in size and demographics had resources such as support groups, special events, and easily accessible information on eating disorders and related resources on the institution’s website. For this project, we made recommendations for improving UD’s resources and we wrote and designed a fact sheet specifically for UD students that provides necessary information on eating disorders that could be made available at various locations on campus, such as academic buildings and residence halls.

Increasing Awareness of Intimate Partner Violence on UD’s Campus College of Arts and Sciences: English Poster - Course Project, 201910 ENG 373 H1 Goal 3: Good Health and Well-Being Goal 4: Quality Education STUDENTS Maria Elizabeth Anderson, Marie Jane Crouchley, Claire Marie Feller ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Many people know that sexual assault is a rising issue on college campuses. However, many do not realize that intimate partner violence (IPV) is also a prevalent issue among college-aged individuals. While the University of Dayton provides many resources on sexual assault, we found there is a need for increased awareness specifically of intimate partner violence. Many students are unaware of the signs of IPV and do not know how to effectively intervene as bystanders of these situations. We examined the impact of existing resources for IPV on UD’s campus and compared them to resources on other college campuses. We determined that there is not enough information readily available for UD students regarding IPV in particular. Our project goal was to create a document that informs UD students of the signs of IPV. Furthermore, our document addresses how friends can support and guide each other in unhealthy relationships. We believe that by providing more information on IPV, UD students will be better equipped to handle these situations and will know where they can get help.

Nutrition Trends and Resources at the University of Dayton College of Arts and Sciences: English Poster - Course Project, 201910 ENG 373 H1 Goal 3: Good Health and Well-Being Goal 4: Quality Education STUDENTS Alicia Marie Abele, Mary Grace Charleton, Serafino Anthony LaGalbo, Nora Catherine Sabo ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 It is no secret that American college students often live off of restricting budgets and inconsistent schedules, both of which can contribute to poor nutritional habits and food choices. According to the Journal of the American Dietetic Association, “25 percent of college students gained more than 5 pounds over the course of eight weeks while transitioning to a college lifestyle. However, a lack of calories can also lead to fatigue and difficulty concentrating at school.” The Center for Disease Control also emphasizes this correlation between student nutrition and academic achievements. Due to the immense importance of nutrition, we investigated the relevance of this trend at the University of Dayton (UD). Our strategies involved researching the current nutritional resources at UD as well as surveying students and interviewing dietetics faculty. Our main goal was to comprehend the correlations between age, living situations, budget, food consumption and weight fluctuations. Our poster will demonstrate these nutritional trends among students and provide suggestions on how to improve dietary habits for the university as well as the students. In addition, we created a flyer for UD students to help spread awareness of the nutritional resources that are available on campus.

Living with Loss: Resources Available to UD Students Grieving the Death of a Loved One College of Arts and Sciences: English Poster - Course Project, 201910 ENG 373 H1 Goal 3: Good Health and Well-Being Goal 4: Quality Education STUDENTS Lexi Diane Brezovec, Henry A Kuechly, John R Moresea ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 College students deal with a variety of stressors throughout their college experience. Several major stressors that arise on college campuses have been heavily researched and publicly addressed, while other stressors are ignored. One particularly prevalent overlooked stressor is the death of a family member or close friend of a student. Research has shown that anywhere from 22-30% of college students have experienced

UN SUSTAINABLE DEVELOPMENT GOALS

the loss of a close friend or family member within the past year. Additional research has shown that living with loss can negatively influence a students’ GPA and social life. Due to such a high percentage of impacted students, along with the impact on GPA and social life, we believe it is important to address this issue and what resources are available to University of Dayton (UD) students. Our research has primarily focused on the resources available at other universities as well as those resources available at UD. After conducting in person interviews and reviewing survey results, we have concluded that this topic is an issue that current UD students face. While many students are impacted by this issue, we discovered limited resources on UD’s campus to assist students in coping with this problem. Due to a lack of resources, our team will propose recommendations along with a brochure for students in order to aid in the grieving process.

Enhancing Knowledge of Test Anxiety Resources at the University of Dayton College of Arts and Sciences: English Poster - Course Project, 201910 ENG 373 H1 Goal 3: Good Health and Well-Being Goal 4: Quality Education STUDENTS Madison Natallia Marquart, Alexa Gabrielle Niceley, Nina Alaine Pappan, Olivia Marie Stanforth ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Test anxiety is a growing concern among college students. According to The American Test Anxiety Association, it is estimated that about 18% of young adults experience moderately high test anxiety. Specifically, at the University of Dayton, the number of students who need special accommodations for their text anxiety increases every year. For this project, resources provided by the University of Dayton were collected and analyzed for their effectiveness and access on campus. After compiling the university’s available options, we concluded that improvements could be made regarding content, accessibility, and awareness. A survey was circulated to UD students, and interviews were conducted with faculty of the Learning Teaching Center and the Counseling Center in order to gain more information on UD’s resources. Resources from other campuses were evaluated and considered in our data collection. Based off of the information we obtained, we created an original brochure for UD students containing a description of test anxiety, its symptoms, and available services for students on campus.

Influenza Vaccine Health Literacy Among UD Intensive English Program Students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Kaylin Ann Kultgen, Nicole Elise Licher, Leigh Anne Roberts, Aubrey Alexandra Woolford ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In the United States, it is estimated that only 12 percent of adults have proficient health literacy. According to Zarcadoolas in Advancing Health Literacy, health literacy is defined as “the wide range of skills and competencies that people develop over their lifetimes to seek out, comprehend, evaluate, and use health information and concepts to make informed choices, reduce health risks, and increase quality of life.” For this project, our group was tasked with finding an original healthcare document in an area of interest or concern for UD’s Intensive English Program (IEP) students. The original document, a vaccine fact sheet from the Centers for Disease Control, was analyzed for readability using the SMOG test and Microsoft Word assessment, identifying the Flesch-Kincaid reading grade level. We also performed a Health Literacy Load Analysis. The original document was then revised to enhance the readability to the IEP students. The first revision was presented to IEP students to gain critical feedback. Though our original document was a more broad outline of how vaccines work, our team chose to focus on the influenza vaccine. This decision was made based on the questions and feedback IEP students provided us, specifically their interest in why some vaccines must be given multiple times. The students’ feedback was used to create a second and final revision of the original document aimed at making information about influenza vaccinations easier to read and understand. We were able to reduce the reading level of the original document to be more understandable and usable for IEP students.

Understanding Headaches: An Analysis and Revision of an Existing Health Document for Intensive English Program Students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Madie O’Brien Clements, Wyatt Andrew Kaiser, Shannon Rae Saelinger, Marrisa Ann Therriault ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Low health literacy serves as a distinct barrier for proper healthcare and affects a large portion of the U.S. population. Our team’s goal was to revise a brochure about headaches to fit the reading level and educational goals of the students in UD’s Intensive English Program (IEP). Our team performed a Health Literacy Load Analysis, SMOG test, and Word readability test to analyze the literacy of a headache brochure from Dr. Schneider’s Clinic, a headache and back clinic in Indiana. The results of these tests found that the reading level of the original document was much higher than the IEP students’ third to fourth grade reading level. We made two visits to the IEP class. The goal of the first visit was to find out what the IEP students already knew about headaches and what information they still wanted to know. Then we revised our existing brochure so that it matched the IEP students’ health literacy levels and incorporated the information that matched their interests. In the second visit, we field tested the revised brochure and received additional feedback from the IEP students to create a more effective final brochure. We were successful in lowering the readability of our brochure from an 11th grade reading level to a 5th grade reading level by replacing complex words and ideas with simpler terms. This project directly shows the need for health materials that are cognizant of individuals with lower health literacy.

Alcohol: A More Effective and Culturally Accessible Explanation for UD’s Intensive English Program Students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Nick Patrick Andriole, Paige Rene Christine Hallstrom, Kennedy Cozette Sana, Megan Lynn Watson ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alcohol consumption is a part of the college culture in the United States and is, therefore, a common health topic of concern on university campuses. However, students in the University of Dayton Intensive English Program (IEP) have limited exposure to and knowledge about alcohol due to the religious practices and the laws in their home countries. Most existing healthcare documents in the U.S. about alcohol are written at a high reading level, which limits the resources available for the IEP students to learn about this topic. Our team conducted a Health Literacy Load Analysis, SMOG test, and Flesch-Kincaid test on a document about alcohol published by the South Australia government. We found that this public health text was written at a 11th grade reading level. Over the course of the project, we met with the IEP students twice: once to assess their information needs and once to field test how well the IEP students understood a draft of our team’s revised brochure. The main purpose of our brochure was to educate the IEP students about alcohol, including common reasons why people drink as well as the effects of consuming alcohol on the body. Our revised brochure was written at a 4th grade reading level and addressed the cultural context of the IEP students. Through our collaboration with the IEP students, we gained a perspective on the necessary work required to make health information accessible to low literacy groups.

and competencies to comprehend, evaluate and use health information to make informed health-related decisions to lower their health risks. Inability to read patient education materials can lead to poor overall health and high mortality. For this project we partnered with students in UD’s Intensive English Program (IEP), and revised two existing healthcare documents on smoking, a topic that was of interest to them, and made a single document that was more readable and useful for the IEP students. During this project, we tested the readability level of both the original documents and the revised brochure using the Microsoft Word test, SMOG test and the Health Literacy Load Analysis test to ensure the readability level was appropriate for the IEP students who read at a 3rd to 4th grade level to comprehend. Based on the results of our research, we reduced the reading levels of the original documents from a 10th and 11th grade level to a 4th and 7th grade level. We also visited the IEP students twice to collect information that they would like to know about our topic and to field test a draft of our brochure. In the end, our goal was to provide these students with a readable, informative, and useful document that can help them better understand the health effects of smoking, the health risks of secondhand and thirdhand smoke, and the reasons that smokers continue to smoke so that they can take preventative health measures if needed.

Revising a Document About Sugar and the Body for UD Intensive English Program Students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Nicholas Bianco, Patrick William O’Brien, Katie Marie Perry, Janeta Y Yancheva ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Having adequate health literacy is important in order for someone to be able to understand medical information that is presented to them. On UD’s campus, a large number of international students speak English as their second language. For this project, we worked with the Intensive English Program (IEP) students to create a brochure about sugar and the body that is more understandable and usable for their literacy level. We met with the IEP students at the beginning of the project to see what they already understood and what they wanted to learn more about. While the average American reading level is 8th grade, the IEP students in this course read at approximately a 3rd-4th-grade level. The goal of our project was to modify an existing document to make it readable and usable for the IEP students. The document we chose came from betterhealth.vic.gov.au. We first analyzed the four domains of health literacy by performing a Health Literacy Load Analysis in order to improve the readability in our final brochure. We field tested the draft with the IEP students once more before finalizing the brochure to gain feedback on their understanding of the material. The completion of the final document was followed with a SMOG and Word test and determined that the reading level was reduced significantly. This project showed us that it is possible to reduce a health document to a lower reading level in order to more effectively communicate health information.

The effects of caffeine on aerobic exercise performance in college student females School of Education and Health Sciences: Health and Sport Science Poster - Capstone Project

Goal 3: Good Health and Well-Being STUDENTS Kiki Marie Hess, Kristina Kay Holmes, Anna Katherine Rose Kolesar, Leah Ann Schneider, Madeline Nicole Smith, Kelsey Morgan Tepe ADVISORS Haozhou Pu LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Studying the effect of caffeine on exercise performance is important to determine the consumption of coffee in exercise. From previous research, it has shown consuming caffeine before exercise has positive effect on exercise, by decreasing rate of perceived exertion and increased exercise performance. The results we find through this research can help others decide whether they would drink coffee before exercising in the future. Since college students consume large amounts of coffee everyday, we want to see how it affects them while exercising. Specifically, we focused on the population of female college students in this project. The purpose of this study is to explore the relationship of caffeine on aerobic exercise performance in college aged females. The caffeine consumed by the participants will be 8oz of donut shop coffee from a keurig cup. This will be consumed one hour before exercise and we will measure aerobic exercise performance using a cycle ergometer. There will be a total of 10 female college aged participants of both coffee and non-coffee consumers. We will have the same 10 females exercise one day without coffee and one day with coffee to compare our results. We are interested in looking at the effects coffee has on heart rate, blood pressure, rate of perceived exertion, and exercise performance (survey-based). The results will be reported at the symposium once our research is concluded.

The purpose of this study will be to explore the best time of day to exercise for college students in order to improve their sleep or get the best quality sleep. To gather data, a survey will be conducted with a sample of college students to obtain quantitative and qualitative results relating to sleep and exercise routines and changes. Possible results for this study may include increased adequate sleep, timing of exercise determined to be in late afternoon, decreased time to fall asleep, and decreased sleep disruptions. These findings will be useful for understanding the most beneficial and optimal time of day to exercise in order to improve the quality of sleep for college students.

Twin Towers Community Nutrition Assessment (micro-level) School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 302 01 Goal 3: Good Health and Well-Being STUDENTS Emily Rose Fritz, Lauren Elizabeth Lynch, Michelle Ann Schick, Leah Elizabeth Wagner ADVISORS Diana Cuy Castellanos LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The Twin Towers neighborhood is a low-income community in East Dayton, located about 1.5 miles away from the University of Dayton campus. The purpose of this assessment was to identify various dietary contributing factors so an appropriate intervention can be implemented to improve the dietary habits of those families and children living in the Twin Tower neighborhood. The objectives were to determine dietary intake, anthropometric, and physical activity habits of the population using secondary and primary data sources. Through a self-reported survey, we found that 81% of the sample population was overweight or obese and exercised an average of 45 minutes each week, which is below the recommendation for physical activity. Generally, families in low income communities have a high intake of saturated fat and a lower intake of fruits and vegetables. Due to this information gained, we recommend implementing a multi-component nutrition and physical activity intervention addressing the overweight/obesity epidemic, as well as the lack in physical activity seen among those in the Twin Towers neighborhood.

Dayton, Ohio itself is ranked 11th in the U.S. for food hardship and many of the children living in Twin Towers area qualify for the National School Lunch Program. The purpose of the community assessment is to analyze the social and political factors associated with the Twin Towers community. The objectives of this project are to analyze, through primary and secondary sources, factors including: food access, employment, income, housing, food policies and programs, political structure, business, and healthcare access in the Dayton Twin Towers community. Major findings include frequent fast food consumption of the Ruskin Elementary students, over half the Twin Towers residents making less than $25,000 per year, the lack of Twin Towers businesses due to the building of the I-35 highway, and barriers associated with accessing National food programs. These barriers include: language barriers, lack of ID for access of food programs, lack of transportation, and lack of education on where and how to obtain access to food programs. In conclusion, addressing these barriers may lead to better dietary outcomes.

ADVISORS Haozhou Pu LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The issue that this study will address is what is the best way to relieve muscle soreness after exercise. More specifically, this study will help determine how different temperature (i.e. hot & cold) will help relieve delayed onset muscle soreness more efficiently. The settings of this project will be to place the participants into a highly heated pool or an ice bath. To collect data, interviews with 4 individuals, 2 males and 2 females, will be conducted. The interviews will be conducted after the individuals exercise to obtain delayed onset muscle soreness (DOMS) information and then either use hot or cold temperatures to relieve it. The exercise will consist of various resistance training focused on the lower body. Participants will exercise their hamstrings, quadriceps, adductors, and so on, which will then lead to the immediate application of heat or cold therapy. The study will also have a control group in order to compare the results to a baseline of the specific exercises without temperature application post-workout. We plan for our data to show results of DOMS in individuals and determine which temperature provides the best relief. The detailed findings will be reported at the symposium.

The Effects of Intermittent Fasting on Weight Loss, Mood and Energy Level School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 428 02 Goal 3: Good Health and Well-Being STUDENTS Connor Stephens Goff, Cosette Mary Riely, Erika Marie Schmitt, Diandra A Walker, Michael C Wroblewski ADVISORS Haozhou Pu LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Between increases in sedentary lifestyles and poor eating choices, America has been fighting the obesity epidemic for decades. Increased advertising convinces consumers that they need to eat more than they do, but intermittent fasting may be the solution to the obesity issue. Intermittent fasting has become a new method for losing weight. It is not a diet meaning it does not dictate what is eaten, but rather dictates what times of the day eating is allowed. Previous research has examined how intermittent fasting can impact weight loss in participants, but none have examined intermittent fasting specifically on college-age students. The purpose of this study is to examine the effects of intermittent fasting on weight loss, mood and overall energy levels in college students. Participants will be randomly assigned to a control group, intermittent fasting with a 8 hour window and intermittent fasting with a 12 hour window. The participants will fill out daily questionnaires to track mood and energy levels throughout the experiment. Results will be presented at the Stander Symposium. The results from this study will contribute to the continuous discussion about healthy ways to lose weight as well as focusing on a population that has limited control over what they eat.

The Effect of Environment on Running Performance and Rating of Perceived Exertion (RPE) School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 428 02 Goal 3: Good Health and Well-Being STUDENTS Julia Margaret Dozeman, Danielle Denise Greer, Kevin Patrick Reider, Jacob Nicholas Stanek ADVISORS Haozhou Pu LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 This research is aimed to discover how different running environments affect running performance and perceived exertion rates. The purpose of this research is to evaluate in what running environment college-aged individuals perform best, based off of time. Research will be conducted at the University of Dayton RecPlex and an outdoor trail near campus. The participants of this study is non-athlete male and female subjects, aged 18-23 years old. While each participant is completing the three one-mile runs, rating of perceived exertion (RPE), heart rate, and time will be recorded. Specifically, the Borg RPE Scale will be utilized to attain subjects’ RPE, and an Apple Watch will be utilized to attain subjects’ heart rate prior to and immediately after each run. Achieving a certain percentage of an individual’s age predicted maximum heart rate is a valid indicator of work exertion. While data collection is not yet fully complete, we are anticipating that, on average, participants will report the lowest RPEs during the outdoor trail run and the highest RPEs while on the treadmill. Although we are expecting to see similar trends in RPEs, we are anticipating that the females, on average, will display longer times recorded for each timed run than the average male times. The environment with the shortest average time, however, is expected to correlate to the environment with the highest RPE rating and highest heart rate. College students will benefit from this research. With busy schedules, college students should know what running environment supports better performance.

The study focused on the Hispanic population of the Greater Dayton Area. A survey was adapted from the Theory of Planned Behavior which served as the measure for intention to seek follow-up care. This survey wasadministered at three separate health fairs. The purpose of a community health fair was to provide baseline measurements for participants, including BMI, body composition, blood pressure, blood glucose, triglyceride levels, etc. The intention to seek follow-up care was then compared with BMI, blood glucose levels and triglyceride levels. It was found that what most strongly correlated with intention to seek follow- up care was the attitude held by the participant about access.

The Twin Towers neighborhood is a low-income, food insecure community located within Highway 35, Wayne Ave, and Wyoming St. The purpose of this was to assess the various dietary-related environmental and community factors that have impacted the overall health and food access of the Twin Towers community. Some of our objectives of this assessment were to obtain primary and secondary data regarding food and nutrition program participation, safe food and meal availability, safe water availability, and food and nutrition-related supplies availability. Overall, the primary data suggested that a majority of participants walk to get food supplies and obtain their food supplies from Kroger, but some participants also obtain food supplies from Ray’s Food Market. Most participants obtain food from these places due to its location close to home. The data also indicated that all participants own a refrigerator, and a majority of participants own a microwave, hot plate burner, and a crockpot. Also, a majority of participants eat food at home but not at a high frequency. The secondary data suggest low ownership of vehicles, a slight decrease in food and nutrition program participation, a slight decrease in annual median income of Montgomery households, high rates of poverty, high safe water availability, and low levels of accessible healthy food providers.Due to these findings, we recommend addressing the barriers to obtaining healthy food available within the Twin Towers environment.

Nicaragua, one of Latin America’s poorest countries, has a high maternal death rate due to lack of access to services, high fertility rate among a young reproductive age group, complications from unsafe abortions, postpartum hemorrhage, hypertension, and sepsis (Lubbock & Stephenson, 2008). Unlike Nicaragua, Cuba, a fellow Latin American country, has strict policies and procedures for prenatal care. Cuba’s use of the polyclinic, a multidisciplinary professional team that works closely with mothers and children in the community, allows for expecting mothers to have access to basic medical care, such as universal screenings and annual checkups, as well as access to medical educational materials and other necessary preventative care. A preventative approach to prenatal care includes prioritizing and tracking high risk pregnancies, and setting national standards that make the life expectancy at birth on par with western nations (Bragg et. al, 2012). As a result of Cuba’s approach, their maternal mortality rate is on the decline while Nicaragua’s’ in on the rise. The purpose of this poster is to describe the prenatal care disparities between Latin American countries, and offer some strategies to combat this problem.

We also investigate well-being differences between online socialization platforms, which we expect to be higher for forum usage than for SNS usage. Finally, we examine mediating and moderating effects of online relatedness, such that (1) online forum relatedness mediates the relation between forum use and well-being and (2) participants with low SNS relatedness and high SNS usage report especially low levels of well-being than do participants with high SNS relatedness regardless of SNS usage.

Perceived Peer Norms, Health Beliefs, and Their Links to Sexual Risk Behavior Among College Students College of Arts and Sciences: Psychology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Cassandra L Hartman ADVISORS Jackson A Goodnight LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Research has shown an increase in risk behaviors (e.g., binge drinking, risky driving, or unprotected sex) during emerging adulthood, a developmental period between the ages of 18 and 25 (Arnett, 2000). Sexual risk-taking is of particular concern due to negative consequences (e.g., unintended pregnancy, contracting a sexually transmitted infection) of this behavior becoming more prevalent, especially among college students (e.g., Turchik & Garske, 2009). The current study investigated how peer norms and personal beliefs about health may work together to explain engagement in sexual risk behavior among college students. It was hypothesized that in the context of strongly held health beliefs (e.g., high perceived susceptibility), the relationship between perceived peer norms surrounding sexual risk behavior and oneâ&#x20AC;&#x2122;s engagement in risk behavior would weaken, while in the context of weakly held health beliefs (e.g., low perceived susceptibility), the relationship between perceived peer norms and ones engagement in risk behavior would strengthen. Further, it was hypothesized that the relationship between perceived peer norms surrounding sexual risk behavior and oneâ&#x20AC;&#x2122;s engagement in risk behavior would be explained by low levels of health belief variables. One hundred and fifty six undergraduates (48 male, 108 females) anonymously completed questionnaires online about personal beliefs about health, personal and perceived peer engagement in sexual risk behavior, and demographics. Hierarchical multiple regression using SPSS tested if the positive association between perceived peer norms and sexual risk behavior was moderated by privately held health beliefs. Bootstrapping (Preacher & Hayes, 2008) was used to test mediation hypotheses. No support was found for health beliefs to moderate or mediate the association between peer norms and sexual risk behavior. There was a strong and consistent direct effect of peer norms on sexual risk behavior across all analyses.

Participants in the social stress condition will undergo one round of Cyberball and participants in the achievement stress condition will take a difficult arithmetic test. Immediately after stress exposure, repeat olfactory testing and battery of questionnaires assessing affect and perceived stress will be administered. Significance:This project will expand the understanding of how affect and olfaction are related, and how sex influences these relations specifically how stress conditions induce negative affect and alter olfactory functioning. Since social impairment is present across a number of psychiatric disorders and olfaction is related to social functioning, understanding the impact of social versus non-social stress on affective state and olfactory function advancements in prevention and treatment of psychiatric disorders can be achieved.

Narratives of Lost Meaningfulness: When Contamination Sequences have Humanistic Themes College of Arts and Sciences: Psychology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Joe Edward DeBrosse ADVISORS John J Bauer LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Life stories’ affective sequences indicate how people feel about the changes in their lives. Contamination is a common affective sequence in which the narrative begins with positive or neutral affect but declines to negative affect. While previous studies showed that contamination sequences predict a variety of poor well-being indices (e.g., McAdams, Reynolds, Lewis, Patten, & Bowman, 2001), whether contamination’s accompanying themes—such as humanistic or materialistic concerns—change their predictive utility for well-being is unknown. Based on the low- and turning-point narratives of 211 participants, we examined whether contamination sequences with humanistic themes (e.g., a loss of meaning due to unemployment) differed in their relations to well-being compared to contaminated narratives without humanistic themes (e.g., a loss of prestige due to unemployment). We predicted that contamination sequences would interact with humanistic themes to predict significantly lower levels of well-being. Though the data showed a trend toward this interaction, contaminated humanistic narratives were exceptionally rare and the interaction was not statistically significant.In addition, we refined the standard measure of contamination sequences into three categories, finding that contamination sequences only predict well-being when they begin with positive, not neutral, affect. A third, new category, bad-to-worse contamination, predicted the lowest levels of well-being.

Personality Risk and Protective Factors Moderate Associations of Relationship Contingent Self-Esteem with Mental Health and Relationship Outcomes College of Arts and Sciences: Psychology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Frane Francis Santic ADVISORS Lee J Dixon LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Relationship Contingent Self-Esteem (RCSE) involves one basing their self-regard on the nature and outcome of their relationship (Knee, Canevello, Bush, & Cook, 2008). RCSE is said to occur from a thwarting of basic psychological needs, including competence, relatedness, and autonomy (Deci & Ryan, 2000, Knee et al., 2008). When these needs are not fulfilled, issues such as feelings of incompetence, a lack of feeling of control, and issues with connecting with other individuals can occur (Hadden, Rodriguez, Knee, & Porter, 2015). Further, those high in RCSE can have lower relationship satisfaction and experience higher levels of negative emotion felt (Knee et al., 2008). The objective of the proposed study is to examine how certain personality risk and protective factors that are correlates of the basic psychological needs influence the relationship between RCSE and relationship satisfaction and the experience of negative emotion (i.e., depression). The study draws from a large sample of married alumni from a private Midwestern US university. Participants were asked to complete a survey containing a range of measures that examine attachment styles, need fulfillment, and other personality factors, as well as what level of depression and satisfaction participants are currently feeling in their lives. Based on moderation analyses, the basic psychological needs were not found to moderate the relationship between RCSE and relationship satisfaction, with the exception of low competence in male participants. For both males and females, low levels of the autonomy and relatedness, as well as high levels of self-alienation, accepting external influences, and anxious attachment were found to moderate the positive association between RCSE and depression. Low levels of self-compassion, competence, and authentic living were found to only moderate the positive association between RCSE and depression for female participants.

One common factor that has increased stress-levels is the implementation of standardized testing. The pressure and weight that standardized tests put on students are detrimentally affecting their grades and overall health. In addition, certain demographics are being more negatively affected by standardized tests; therefore, putting specific groups at a disadvantage. As a result of increased anxiety, schools have started to address the need for programs that assess and assist students’ mental health. The first step many schools take is figuring out sources of anxiety for students. Educators and administrators have realized the importance of offering counseling for students as well as increasing awareness of mental health, as it has proven to lower anxiety levels. However, many obstacles still fall in the way of resources being available to all students, whether it be social pressures or outside factors that impact the school. As future educators, we are interested in researching why anxiety has increased in students in recent years, and how it can be addressed. We believe that teachers should help develop their students as people, not just focus on the student’s academic performance.

The Effect of Remote Ischemic Preconditioning on Exercise Hyperemia and Reactive Hyperemia in Individuals with Multiple Sclerosis. School of Education and Health Sciences: Health and Sport Science Oral Presentation - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Elizabeth Anne Goetz, Jane Elise Rosmarin ADVISORS Anne R Crecelius LOCATION, TIME Kennedy Union 311, 10:20-11:00 This presentation shows how an intervention called remote ischemic preconditioning (RIPC), which briefly occludes circulation to the leg, can affect exercise capabilities and blood flow in people with and without Multiple Sclerosis (MS). MS is an autoimmune disease that can cause symptoms like fatigue and weakness. RIPC has been shown to elicit a protective effect throughout the body which could alleviate these symptoms. To determine the effects of RIPC, ultrasound was used to determine flow-mediated dilation during a hand grip exercise. In addition, a strain gauge was used to determine forearm blood flow during reactive hyperemia (blood flow following a period of occlusion).

Age-Dependent Effects of Short Chain Fatty Acids on Bacterial Burden In Vivo After Oral Infections with Listeria monocytogenes strains 10403s and 07PF0776 College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Leah O’Malley Allen, Julia I Chapman, Ashton Nicole Dix, Paul Robert Maricocchi, Melani Muratore, Sam Lee Neanover, Erica Marie Rinehart, Nathan C Wallace ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Listeria monocytogenes (LM) is a foodborne pathogen that establishes its intracellular life cycle inside mammalian host cells. In elderly individuals, LM infections can spread to peripheral organs, causing meningitis with high mortality rate. We have previously shown that short chain fatty acids (SCFAs), fermentation acids found in large quantities in the intestinal lumen, exhibit strong regulatory effects on LM virulence gene regulation. In this study, we investigated the effects of SCFAs on LM virulence using an oral feeding model of LM infection with two different LM strains in young (2 months) as well as old (16-18 months) female BALB/c mice. LM strains used in this study include the serotype 1/2a strain 10403s and the cardiotropic serotype 4b strain 07PF0776. Mice were given SCFAs, individually as well as in two different

UN SUSTAINABLE DEVELOPMENT GOALS

combinations, in drinking water for four weeks, starved for 24 hours, and orally infected with LM-ladened Nutella. At five days post infection, organs (spleens, liver, heart, gallbladder, ileum, and colon) were harvested and homogenized to enumerate LM colony forming units. We found that for both LM strains, SCFA supplements render the young mice more susceptible to infections but prevent old mice from succumbing to infections. Furthermore, low levels of SCFA mixtures led to a decrease in bacterial burden in the heart of old, but not young, animals infected with the cardiotropic strain 07PF0776. To better understand the different infection outcomes by strains 10403s and 07PF0776, we characterized their LLO production in response to SCFAs in vitro under aerobic or anaerobic conditions. We noted that the presence of low levels of SCFA mixture under anaerobic conditions significantly enhanced LLO production in 10403s but not in 07PF0776. These results indicate that there is a strain-dependent difference in LM response to SCFAs. Moreover, there is an age-dependent effect of exogenous SCFAs on the outcome of animal infections.

Evolutionarily conserved Wingless signaling pathway is regulated by newly identified newt genes to trigger regeneration response in Drosophila. College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Abijeet Singh Mehta ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Notophthalmus viridescens possess amazing regeneration capabilities but due to lack of available genetic tools the mechanism driving such regeneration has not been well understood. Here we used Drosophila imaginal discs to study regenerative role of five newly identified newt proteins that have new sequence motifs. These proteins were identified by denovo assembly of newt transcriptome combined with proteomic validation. Using transgenic approach these genes were misexpressed in developing eye field of early as well as late eye Drosophila mutants where cell death was induced in photoreceptor cells during early 2nd instar (in early eye mutants) and late 3rd instar (in late eye mutants) stage, respectively. The penetrance of mutant phenotype was 0%. Strikingly, Newt genes when expressed in the background of such mutants show significant regeneration of missing eye tissue. Even more, these genes having signal peptides, exhibited non-autonomous regeneration as shown by domain specific misexpression on candidate genes, and flip out clones. Using Retinal determination (RD) fate markers, we demonstrated that regeneration response was restricted only to fly eye field. These regenerated tissues (eyes) showed 6 Âą 1.5 folds increase in mitotic index as compared to the mutants. In comparison, there was only 1-fold downregulation of cell death, suggesting that newt regeneration genes employ cell proliferation function to promote regeneration. Additionally, downregulation in apoptosis is preventing regenerated tissue from further death. Using RNA sequencing, we identified the role of signaling pathway that has been perturbed by newt genes to induce regeneration in Drosophila. We found that member of evolutionarily conserved Wnt/Wingless (Wg) pathway exhibit 4-fold downregulation of expression. Additionally, the genes related to the molecular class of development, apoptosis and cell cycle were highly enriched. Using immunohistochemistry we verified RNA Seq results, and found that Wg is significantly downregulated by these newt genes to promote regeneration. Perturbing positive and negative regulators of Wg signaling pathway and blocking Wg transport revealed that newt genes regulate Wg/Wnt pathway in regenerative response. Our results demonstrate a unique class of genes present in Newts which employ conserved pathways to trigger regeneration response, and also provided a novel platform to bridge the gap of unraveling the mechanism behind regeneration tool kit from newts.

Finding the switches that activate animal genes through a combined in silico and in vivo approach College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Chad Michael Jaenke ADVISORS Tom M Williams LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The DNA sequences of genomes encode the recipes for making functional cellular products, notably proteins, and switches that regulate when these products are made. While the genetic code for proteins has been known for decades, a similar code for the regulative switches is lacking. This presents a major challenge to understanding the genetic basis of life, as these switches (called cis-regulatory elements or CREs) may outnumber protein-coding genes by 20-50 fold. Both in vivo and in silico approaches exist to study CREs, but the former approaches are generally low throughput and not up to the scale of vast genomes, and the latter lack validation of predictions. We are merging in silico and in vivo approaches to identify the CREs controlling genes responsible for a fruit fly pigmentation trait. Here, we are leveraging the knowledge of five CREs that switch on the transcription of five different genes from a fruit fly tergite pigmentation gene regulatory network (GRN). We are using the SCRMshaw bioinformatic tool to identify novel predicted CREs controlling genes within this GRN based on underlying similarities in the DNA sequences of the known CREs. From this novel list, we will test 24 for CRE activity in in vivo reporter transgene assays. The results

from these tests will reveal to what extent the in silico method succeeded. Novel validated CREs will be compared with the known five to reveal what the molecular functions are for the common DNA motifs as the next stage of this research project. The encoding of information in CREs is a universal feature of life, so these results bear upon life at every level, including the betterment of the human condition.

Discovering Glioma Inhibitors via Chemical-genetic Screens in Drosophila Cancer Models College of Arts and Sciences: Biology Stander Undergraduate Fellowship Awardee Poster - Honors Thesis Goal 3: Good Health and Well-Being STUDENTS Jordan M Terschluse ADVISORS Madhuri Kango-Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Through all the medical advancements made in cancer detection and treatment over the centuries, there still is no cure for most cancer types. A class of chemicals called tyrosine kinase inhibitors seems the most promising, as most cancers show activation of tyrosine kinase dependent oncogenic pathways. However the efficacy of these drugs is poor, suggesting that new approaches like combination therapy need to be tested. In this approach, two drugs that show mild effects are tried in combination to check for additive effects or improved efficacy. In our lab, we analyzed the effects of both the promising class of tyrosine kinase inhibitors as well as Temozolomide, a chemical that has shown immense success in treating human glioma patients. These effects were analyzed using a Drosophila glioma model, due to Drosophila melanogaster having a high percentage of conserved genes that are known to cause diseases in humans. Using these orthologous genes, it is possible to model human diseases like glioma in flies, and the results from flies may be extrapolated to mammalian models. Results from these studies will be of immense importance to the medical field, specifically dealing with different treatment options for patients.

Interaction between axial patterning gene (dve) and Dpp signaling during eye development in Drosophila College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Neha Gogia, Katie Marie Perry, Akanksha Raj ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 An interesting question in developmental biology is how any three dimensional organ develops from a single monolayer sheet of cells. Organogenesis in multicellular organisms requires an important process of axial patterning which marks the development of Antero-Posterior (AP), Dorso-Ventral (DV) and Proximo-Distal (PD) axes. Out of these axes, Dorso-Ventral (DV) patterning marks first lineage restriction event and any disturbance during these axes development leads to defective organ/s formation. In our research we have studied how cell signaling mechanisms interacts with cell fate specification genes and forms eye as an organ. We have used, Drosophila melanogaster (a.k.a fruit fly) as our model organism and Drosophila eye as our model organ (as the genetic machinery is conserved between fruit flies to humans, and any insights generated here can be extrapolated to humans). Previous data from our lab confirms defective proventriculus (dve-a Homeobox gene), an ortholog of SATB homeobox 1 (special AT-rich sequence binding protein 1, in humans), acts as a new member of DV patterning gene hierarchy. In this research, we present that, DV patterning gene (dve), interacts with Dpp signaling. Our results using Gain-of-function (GOF) studies confirms that upregulation of the levels of Dpp signaling by misexpression of decapentaplegic (dpp) and mother against dpp (mad) in dve expression domain results in downregulation of wingless and dramatic eye enlargements. In contrast, downregulation of Dpp signaling by misexpression of brinker ( brk), an antagonist of Dpp signaling in Drosophila, in dve expression domain leads to ectopic induction of wingless in posterior domain of eye and eye suppression or reduced eye phenotypes. In future, we will test if these eye phenotypes are a result of the change of cell fate or due to induction of developmental cell death. To address this, we will test what happens to retinal determination and cell death markers in this background. This study may have a significant bearing on growth, signaling and patterning defects and helps to understand the etiology behind genetic birth defects in the eye.

Modulation of Listeria monocytogenes Carbon Metabolism by Short Chain Fatty Acids College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Diksha Bedi ADVISORS Jeremy M Erb, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00

UN SUSTAINABLE DEVELOPMENT GOALS

Listeria monocytogenes, a bacterial pathogen, is associated with foodborne infections in humans. Listeria encounters short chain fatty acids (SCFAs) during its transit through the intestine but its metabolic responses to SCFAs are not fully understood. To determine how Listeria metabolism is affected by SCFAs, I performed basic microbiology assays, including monitoring optical density, determining acetoin production, and measuring culture pH levels. I also performed preliminary 13C-NMR assays to provide a more in-depth look into carbon metabolism in SCFA-treated Listeria. I found that propionate-supplemented Listeria produced significantly more acetoin compared to no supplemented controls. Because acetoin is a product of central carbon metabolism, my result suggests that Listeria is capable of changing its carbon metabolism in response to propionate. My preliminary 13C-NMR results have not revealed how carbon metabolism is altered by propionate and are under current investigation. Further investigation will provide more knowledge in the metabolic mechanism associated with Listeria responses to SCFAs during intestinal transit.

Establishing the Effect of Ethanol on Listeria Infection College of Arts and Sciences: Biology Stander Undergraduate Fellowship Awardee Poster - Honors Thesis Goal 3: Good Health and Well-Being STUDENTS Ryan E Restrepo ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Excessive alcohol consumption has long been an issue in the United States. Listeria monocytogenes (LM), a foodborne pathogen, was used as an experimental model to investigate the impact of alcohol consumption on opportunistic infections. During LM infections, LM can pass through the intestinal epithelial barrier and infiltrate immune macrophages tasked with preventing the spread of infection. Once inside the macrophages, LM produces the toxin Listeriolysin O (LLO) in order to proliferate in the host cell cytosol. Previous experiments have shown that alcohol consumption increases intestinal permeability for LM. Furthermore, in the presence of alcohol LM was shown to have a reduced LLO production. Through the use of RAW 264.7 macrophage cell cultures, the effect of alcohol on immune cell function was studied. These experiments were conducted in order to establish a more complete picture of the effect of alcohol on human susceptibility to LM infection.

Propionate Perturbation of Listeria monocytogenes Growth and Listeriolysin O Production is Modulated by Anaerobicity College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Jack Clifford Weis ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Propionate is a common food preservative and one of the major short chain fatty acids in the human intestines. Therefore, exposure to propionate is a frequent event for foodborne pathogens and likely takes place under suboxic conditions. However, it is not clear whether the absence of oxygen affects how pathogens respond to propionate. In this study, we investigated how propionate exposure affects Listeria monocytogenes growth and virulence factor production under aerobic or anaerobic conditions. Under anaerobic conditions, propionate supplementations had no effect on planktonic growth but resulted in decreased adherent growth. In contrast, under aerobic conditions, propionate supplementations resulted in a pH-dependent inhibition of planktonic growth and increased adherent growth. The effects of propionate on planktonic growth are also temperature-sensitive. At room temperature, propionate supplementation resulted in decreased doubling times under aerobic but not anaerobic conditions. To begin to investigate the effects of oxygen on L. monocytogenes response to propionate, we further noted that supernatant from cultures grown with propionate contained an increased amount of acetoin under aerobic conditions and a decreased amount of ethanol under both aerobic and anaerobic conditions. Moreover, L. monocytogenes grown with propionate exhibited an increased proportion of odd number straight chain fatty acids in a manner that was more pronounced under anaerobic conditions. Finally, aerobic suppression of listeriolysin O (LLO) production and anaerobic induction of LLO production were observed in L. monocytogenes grown with propionate. These results clearly demonstrate for the first time that L. monocytogenes exposure to propionate resulted a variety of physiological and pathogenic responses. Moreover, the presence or absence of oxygen plays a critical role in shaping L. monocytogenes responses to propionate that can potentially impact bacterial survival in the environment and subsequent interactions within host cells.

Goal 3: Good Health and Well-Being STUDENTS Minh T Ho ADVISORS Madhuri Kango-Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Drosophila is a powerful genetic model system to study cancer. In patients, a small number of mutations accumulate in cells which change their growth characteristics and eventually lead to formation of tumors. These tumors are clonal in origin, meaning the cancer arose from proliferation of a single rogue cell. We have developed similar “clonal” cancer models in Drosophila wing and brain to study how tumor cells interact among each other and with their neighbors. My goal is to develop tools to manipulate either the tumor or the normal neighboring cells and test the effect of tumor growth and progression.

The Effects of Sublethal Ampicillin Exposure on Listeria monocytogenes Virulence College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Marlena Rae Merling ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Antibiotics can be found in sublethal levels environmentally as pollution and within the body when used as medication. Antibiotics induce stress responses and sometimes act as signalling molecules in bacteria. In order to better understand the relationship between antibiotics and bacterial infections, the effects of sublethal antibiotic exposure on the ability of Listeria monocytogenes to infect macrophages was studied. Listeria monocytogenes is an intracellular pathogen of the gastrointestinal tract that is facultatively anaerobic. Two strains of Listeria monocytogenes were tested: a lab strain and a clinical cardiotropic strain. The strains were grown in liquid media overnight aerobically or anaerobically with either no antibiotics or with a 0.05 μg/mL concentration of ampicillin, which is the main antibiotic used to treat Listeria infections. Bacteria from the overnight cultures were used to infect RAW264.7 cells (macrophages) at a multiplicity of infection of 10. The number of intracellular colony forming units (CFUs) were measured at 2 and 24 hours post-infection by plating the cellular lysate. Using the number of intracellular CFUs, the percent input was calculated to measure amount of Listeria present inside the macrophages at each timepoint. The results for both strains showed no significant difference in the ability to infect and replicate inside macrophages between Listeria grown with or without ampicillin. Interestingly, the aerobically grown cardiotropic strain had a significantly lower percent input than the lab strain at 2 hours post infection, but there was no significant difference in percent input between the strains at 24 hours post infection. This suggests that although the cardiotropic strain cannot infect macrophages as well as the lab strain, it can either grow better or resist macrophage killing better than the lab strain. Future directions include testing higher levels of antibiotics and exploring the differences in virulence between strains of Listeria monocytogenes.

The Effects of Propionate on the Interactions of Listeria monocytogenes with the Mucosal Barrier College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Katie Lynn Breitenbach ADVISORS Jana M Bennett, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Listeria monocytogenes is a food borne pathogen that is capable of causing the disease listeriosis typically in the elderly, pregnant women, or immunocompromised people. It has a relatively high death rate in the U.S. compared to other foodborne pathogens—about 1 in 5 cases ends in death. The bacterium is an intracellular pathogen, which means it requires entrance into a host cell to carry out its pathogenic activity, grow, and spread. To do this, it must cross the mucosal barrier of the intestinal lining. Through a series of various protocols, this study primarily investigates how anaerobic conditions and short chain fatty acids such as propionate, to which we know Listeria is regularly exposed in the gut, affect the bacterium’s ability to interact with the mucosal barrier. In addition, this study also contributes an understanding of how the disease should be addressed ethically in the U.S. today.

Understanding the development of antibiotic resistance in Listeria monocytogenes College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Andrea Marie Vietti ADVISORS Yvonne Y Sun

UN SUSTAINABLE DEVELOPMENT GOALS

LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Bacterial antibiotic resistance is on an alarming rise worldwide, thus posing an urgent threat to human health. The rise in antibiotic resistance can be attributed to the overuse and misuse of antibiotics in both the healthcare and agricultural industries. In order to address this concern, this research is aimed to identify environmental conditions that may lead to the development of antibiotic resistance in Listeria monocytogenes. Listeria is a foodborne pathogen capable of causing the disease listeriosis especially in immunocompromised populations. Although infected individuals are treated with antibiotics, an alarmingly high mortality rate of 20 percent still persists; thus, it is important to further understand the impact various environmental conditions may have on the development of antibiotic resistance. Various genetic mutants of Listeria were exposed to antibiotics commonly used to treat Listeria infections, and the susceptibility to these antibiotics was observed under environments with and without oxygen.

The Role of Short Chain Fatty Acids in the Activation of Macrophage Production of Nitrogen Radicals by Listeria monocytogenes Infections College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Megan Rose Bias ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Macrophages are important immune cells that can help protect our health by engulfing and destroying pathogens. For macrophages to work, they must be activated when there is a threat. My study focused on testing the effect of propionate, acetate, and butyrate on the ability of macrophages to produce nitrogen radicals. Propionate, acetate, and butyrate are short chain fatty acids that are present in the human body. They help with regulatory functions that are important for our health. We do not yet know how these short chain fatty acids can affect the macrophagesâ&#x20AC;&#x2122; ability to destroy possible threats. Macrophages have many ways to destroy pathogens, such as the production of nitrogen radicals. The production of nitrogen radicals can be measured through a nitrite assay. The macrophages were infected with Listeria monocytogenes that had been treated with one of the short chain fatty acids and then we measured the amount of nitrite production in the cell media. High levels of nitrite indicate high nitrogen radical production. Results from my study helped me understand how short chain fatty acids impact susceptibility to infections in the human body.

Interaction between JAK STAT pathway and axial patterning genes in Drosophila eye development College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Neha Gogia, Akanksha Raj ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Axial patterning is the fundamental process of organogenesis, which entails delineation of three distinct axes: Antero-Posterior (AP), Dorso-Ventral (DV) and Proximo-Distal (PD) axes. Any impairment in the axis formation may lead to developmental birth defects in humans and therefore, getting insight of the mechanism of axis determination is crucial for better understanding of organogenesis. In Drosophila eye model, DV patterning is the primary lineage restriction event. A new member of DV patterning gene, defective proventriculus (dve, a Homeobox gene), an ortholog of SATB homeobox 1 (special AT-rich sequence binding protein 1) has been identified which acts downstream of a GATA-1 transcription factor pannier (pnr), and upstream of wingless (wg) in the dorsal gene hierarchy. Unpaired (Upd), a long range secreted ligand for JAK STAT pathway, is known to promote eye development by negatively regulating Wg expression. Here we present that Upd interacts with dve, to regulate the patterning and growth of the developing Drosophila eye. We found that activation of JAK STAT pathway in dve expression domain results in dorsal eye enlargement and downregulation of Wg expression whereas its inactivation in Dve domain results in eye suppression phenotype and upregulating Wg expression. Our data strongly imply that Upd plays a crucial role in defining the functional domain of Dve during DV axis formation of developing eye. We will present the complex interactions between these two highly conserved pathways, viz., JAK-STAT and dorsal eye fate selectors in growth and patterning of the eye.

UN SUSTAINABLE DEVELOPMENT GOALS

LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Alzheimer’s disease (AD) is a debilitating neurodegenerative disorder with no cure and few effective treatments. AD causes profound cognitive deficits and memory impairments. Here we use a Drosophila model of AD to study the interactions between diseased and healthy cells to better understand the spread of the disease through the brain. Accumulation of the peptide amyloid beta into plaques is one of the characteristics of the disease. A 42 amino acid peptide, Aβ42, is a cleavage product of Amyloid Precursor Protein. Aβ42 tends to aggregate and forms oligomers, eventually making up the plaques seen in the disease. Human Aβ42 can be expressed in the developing retinal cells of fruit flies. In this study we use twin-spot MARCM (Mosaic Analysis with a Repressible Cell Marker) with the FLP/FRT system to express Aβ42. This yields animals with GFP-negative WT cells adjacent to GFP-positive Aβ42-expressing cells in a heterozygous background. We found that populations of Aβ42-expressing cells are much larger than the adjacent populations of WT cells. This suggests that cell-cell signaling between the two populations may be either interfering with the proliferation of WT cells or inducing cell death at a later stage in development. Previous research has implicated Aβ42 in the aberrant activation of pathways leading to cell death. Here we present evidence that signaling between Aβ42-expressing cells and adjacent WT cells mediates neurodegeneration.

Goal 3: Good Health and Well-Being STUDENTS Neha Gogia, Chris Y Kang, Dena M Schaeffer, Catherine Jean Yeates ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Alzheimer’s disease (AD) is a neurodegenerative disease that affects more than five million individuals in the United States alone, where it is the sixth leading cause of death. While there is currently no cure for the disease, it is a highly investigated topic of research. The Drosophila melanogaster eye model is an excellent system to study AD, due to the highly conserved genetic machinery shared between flies and humans. We have developed a transgenic fly model of AD in which we use the GAL4/UAS system to misexpress high levels of human Aβ42 peptides in the differentiating photoreceptor neurons in the fly eye. We use this system to determine whether modulating the function of the calcium signaling pathway can modify Aβ42 mediated neurodegeneration. We used RNAi to knock down six components of the calcium signaling pathway (stim-RNAi, serca-RNAi, orai-RNAi, inx2-RNAi, ip3r-RNAi, and plc 21c-RNAi) in an Aβ42 background in the eye and observed the effects in both eye antennal imaginal discs and adult eyes. Our results showed evidence that knocking down components of the calcium signaling pathway may ameliorate the neurodegeneration mediated by Aβ42. Aberrant calcium signaling has also been implicated in cancer and other neurological diseases besides AD. Our research further implicates intracellular calcium signaling in neurodegenerative disorders such as AD. Further research will determine the molecular mechanisms linking calcium signaling with Aβ42 mediated neurodegeneration.

Understanding the Link between Sugar Diet and Alzheimer’s Disease using Drosophila Eye Model College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Jordan Clay Dubbs, Neha Gogia, Akanksha Raj, Ankita Sarkar, Ian Joseph Tobal ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Alzheimer’s disease (AD), is a progressive neurodegenerative disorder and is the sixth leading cause of death in the United States (US), with no cure to date. It is caused by abnormal cleavage of amyloid precursor proteins (APP), generating amyloid-beta-42 (Aβ42) plaques that trigger neuronal cell death by unknown mechanism(s). Neuroinflammation (body’s response to repair, damage and defend against foreign agents) is another characteristic feature of this disease. According to US Department of Agriculture (2017), an average American consumes 94 g of sugar per day which is equivalent to amount of sugar in 2.4 cans of coke. The impact of this high amount of blood sugar can be very significant as breakdown of glucose in high-sugar diet damages the enzymes that regulate inflammation (in immune responses), resulting in misregulated neuroinflammation, strokes, and chemical imbalances, and thus may contribute towards AD. In our study, we want to elucidate the effect of both high and low sugar diet on Alzheimer’s. To test our hypothesis, we have used Drosophila melanogaster (a.k.a. fruit fly), (as genetic machinery is conserved from flies to humans) and developed a fly model of AD, where human Aβ42 peptides can be misexpressed in Drosophila eye using GAL4/UAS system. We placed flies expressing human Aβ42 in eyes as well as the central nervous system on regular, low, and high sugar diet. We examined the phenotypes in eye imaginal discs, adult flies and collected final death count. We also performed a series of behavioral assays to understand the impact of these different diets. Our study shows that a high-sugar diet displays a more aggressive progression of AD as compared to a normal diet or a low-sugar diet. This research has significant bearings in understanding the potential link between AD and diabetes, as both are very prominent diseases in today’s world.

Investigating the Role of a p53 Mutation in Glioma Progression and Therapy Resistance in Drosophila College of Arts and Sciences: Biology Stander Undergraduate Fellowship Awardee Poster - Independent Research Goal 3: Good Health and Well-Being STUDENTS Kaitlyn M Alleman ADVISORS Madhuri Kango-Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Gliomas, which are brain tumors that arise from glial cells, are some of the most aggressive and lethal types of tumors. These brain tumors are difficult to treat because not enough information regarding the mutations present in these tumors exists. This project studies effects of a p53 mutation on Drosophila glioma progression and then will test to see if this results in resistance to current chemotherapy. Drosophila are used as model organisms to mimic these processes. The current genetic crosses that have been created will be studied, and an effective p53 knockdown will be made. In essence, this will effectively mimic a human brain tumor so the treatments tested and the data collected from this model can be applied to the current understanding of human gliomas. In addition to studying just the p53 mutation, additional mutations will be added. This will lead to an even more accurate glioma model because multiple mutations, such as the ones added are present in human tumors as well. These genetic crosses will be treated with Tyrosine Kinase Inhibitors, which are currently used to treat brain cancer patients in order to find out whether or not this mutation plays a role in resistance to current therapy. The main goal of this endeavor is to investigate the numerous defects occurring at the cellular and biochemical level in gliomas, which will give insight into why these types of tumors are so difficult to treat. Data gathered from this project will lead to further inquiry into the role of p53 mutations in gliomas and hopefully, to better outcomes for those affected by this type of cancer. Here, we present the data gathered from this project thus far.

Antibiotic Resistance to Rifampin, Streptomycin, and Penicillin in Grasshopper Bacterial Isolates College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Lauryn E Brasch, Melani Muratore ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Antibiotic resistance is a growing epidemic from excessive use of available antibiotics that is leading to a global health crisis. As more antibiotics are being misused, killing susceptible bacteria, more resistant bacteria grow to be prominent in the population. Given the ability of bacteria to exchange genetic information, high prevalence of antibiotic resistance poses a great threat to make killers out of bacteria that were formerly treatable. Grasshoppers are critical players in the ecosystem serving as a connector between soil, plant, and animal. Grasshoppers are also the most consumed insect by humans. Therefore, if grasshoppers can serve as a vector to spread antibiotic resistance in the environment, they might provide a potential target to halt the antibiotic resistance epidemic. In this study, we examined whether antibiotic resistant bacteria are present in a wild grasshopper. A male grasshopper was dissected and its gut content was diluted and plated on LB agar. Different bacterial isolates were obtained. To test for antibiotic susceptibility in these bacteria, disc diffusion assays were performed by spreading the bacterial isolate on LB agar and placing discs that contain antibiotics Rifampin, Streptomycin, and Penicillin on the agar. After 24 and 48 hours, the diameter of the growth inhibition zone was measured in mm. The bigger the diameter, the more susceptible the bacteria are to the antibiotic. Out of the 17 isolates, only three were susceptible to Penicillin, demonstrating that there was a high level of Penicillin resistance. In contrast, 16 out of 17 isolates show susceptibility to Rifampin. Fewer isolates are susceptible to Streptomycin but the diameter for the zone of inhibition was larger. From these results, it is clear that antibiotic resistant bacteria are indeed present in the grasshopper, potentiating grasshoppers as a vehicle of antibiotic resistance transmission.

These tumors cause the larvae to enter a prolonged larval phase, and eventually kill the organism. We are conducting a chemical screen using Tyrosine kinase inhibitors (Selleck Biochem.) in which we feed early third instar (72h old) larvae 10 or 300uM chemicals in DMSO and then see effects on glioma growth, and survival in mature third instar stage (120h old). Using these metrics, here we present data from our screen pertaining to drugs from rows A, B, C, and D of our library. Once we identify potential glioma inhibitors in the primary screens, we will validate them in secondary screens.

Microbial Resistance to Traditionally Medicinal Plant Extracts College of Arts and Sciences: Biology Stander Undergraduate Fellowship Awardee Poster - Independent Research

Goal 3: Good Health and Well-Being Goal 12: Responsible Consumption and Production STUDENTS Emilee Kay Zoog ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Microbial resistance to pharmaceutical antibiotics is a growing problem in healthcare and animal husbandry that has led to hundreds of deaths from bacterial infections that could once be cured with antibiotics. Scientists are currently studying these resistance mechanisms and formulating novel treatments for bacterial infections, but exhaustive research of the antimicrobial properties of many common plants has yet to be established. In this study, I tested five traditionally medicinal plants common to the Dayton area including wild hydrangea, black haw, dandelion, mayapple (roots), and red clover for antimicrobial action against several strains of the human pathogens Listeria monocytogenes, Staphylococcus aureus, and Escherichia coli, using disk diffusion assays in aerobic and anaerobic environments. Each extract had antimicrobial activity against at least most of the pathogens tested, but each pathogen reacted variably to each extract, though antimicrobial activity in both oxygen environments were comparable. This suggests that there may be active compounds in plants with antimicrobial properties, in which case said compounds should be isolated and tested further in order to better understand bacterial defense mechanisms in plants, and what, if any, benefit these antimicrobial properties could have for humans with bacterial infections.

Identifying Natural Inhibitors of Bacterial Efflux Pumps College of Arts and Sciences: Chemistry Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Marrisa Ann Therriault ADVISORS Matthew E Lopper LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Antibiotic resistance is a constantly progressing epidemic. Many strains of bacteria have developed a resistance to antibiotics, resulting in prolonged sickness and death. Resistance can be to a specific drug (single drug resistance) or to multiple drugs (multi-drug resistance). This resistance can be caused by a tripartite protein pump called an efflux pump that extends through the inner and outer membranes of the bacterium to pump antibiotics from the inside of the cell to the extracellular environment. In E. coli, the efflux pump is called AcrAB-TolC. In an effort to combat the problem of multidrug resistance, I sought to identify inhibitors of the AcrAB-TolC pump by screening extracts made from edible plants. I identified one plant extract that appears to block efflux pump activity in live E. coli cells and can sensitize the cells to the antibiotic, carbenicillin.

making it difficult for the bacteria to receive the intended dose of the drugs. I have investigated the bacterial efflux pumps and their role in conferring multidrug resistance. I sought to identify new efflux pump inhibitors through the screening of extracts made from edible plants and through the development of synthetic nucleic acid aptamers that bind to the efflux pumps and block their activity.

Analysis and Review of the Effects of Bacterial Competition on Efflux Pump Inhibition College of Arts and Sciences: Chemistry Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Bo A Leszcynski ADVISORS Matthew E Lopper LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Multidrug resistant antibacterial strains are a dangerous problem in modern medicine. One way that bacterial strains can become resistant to common antibiotics is by overexpressing efflux pumps, which are transporters in the cells’ membranes that pump antibiotics out of the cell. The goal is to find inhibitors of bacterial efflux pumps that might reverse the multidrug resistance characteristic. The potential for solving this problem might be found in mother nature. When cells of two different strains are grown together, they must compete with each other for nutrients. This competition can lead to the production of compounds that are toxic to the competing strain. One such compound may be a compound that inhibits the efflux of antibiotics from the cell. To address the multidrug resistance problem, microbes that are known producers of antibiotics will be analyzed and it will be determined if they can produce efflux pump inhibitors that might be therapeutically valuable for us. Preliminary results indicate that two strains, S. griseus and P. polymyxa, might indeed produce an efflux pump inhibitor when they are grown together.

Combating Multidrug Resistance in Bacteria by Inhibition of Efflux Pumps College of Arts and Sciences: Chemistry Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Donny Edward McKenna ADVISORS Matthew E Lopper LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Since the discovery of antibiotics, many otherwise deadly infections have been rendered mere inconveniences. Unfortunately, as antibiotic use has increased over the course of the last century, bacteria have been given more and more opportunities to adapt. Antibiotic resistance allows bacteria to survive in the presence of antibiotics, thus continuing the infection and rendering treatment useless. Bacteria have developed many different mechanisms that confer resistance, among these is overexpression of E. coli’s AcrAB-TolC efflux pump in the cell membrane. The efflux pump, necessary for expulsion of wastes and toxins from the intracellular space, is present in all E. coli cells, however it is present in much larger numbers in resistant cells. This increase in expression allows E. coli to pump out toxins at a much higher rate, thus preventing the antibiotic from accumulating within the cell to reach a therapeutic dosage. An inhibitor of AcrAB-TolC would decrease the rate of efflux and allow accumulation of antibiotics. In order to discover inhibitors, edible plants were obtained and extracts were created and tested in an ethidium bromide-based efflux assay. Green tea extract was found to have significant inhibitory activity. HPLC was used to separate the components of the green tea extract to aid in identification of the active compound. NMR analysis of the active fraction was consistent with a type of aromatic molecule known as a catechin.

The overexpression of these bacterial efflux pumps renders our antibiotics ineffective. I have determined that Yerba Mate extract causes accumulation of a fluorescent dye in live bacterial cells and might, therefore, also cause accumulation of clinically relevant antibiotics. I will test the Yerba Mate extract for efflux pump inhibition in the presence of antibiotics and fractionate the crude extract to identify the active compounds that could be inhibiting the efflux pump. This research could open up a new avenue in the treatment of multi-drug resistant bacterial infections.

In addition, DL based generative methods are also used for image denoising and restoration tasks. In particular, the generative models have applied for enhancement and restoration of Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) images and achieved state-of-the-art performance for noise cancelation and restoration. In this work, we apply different generative model including Generative Adversarial Network (GAN), and denoising convolutional auto-encoder for bio-medical image enhancement problem. The experiments are conducted on different publicly available datasets for MRI and CT images. The experimental result shows promising outputs which can be applied for different applications in the modalities of MRI and CT.

A Comparative Analysis of Breast Cancer Treatments and the Role of Taxane-based Chemotherapy-induced Peripheral Neuropathy on Postural Stability School of Engineering: Mechanical and Aerospace Engineering Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Paige Lynn Ingram ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Twelve percent of women suffer from breast cancer each year, but survivorship is increasing due to improvements in treatments. However, it appears there are lasting effects after treatment due to the toxicity of chemotherapy compounds. One of the most severe side effects is peripheral neuropathy which results in decreased sensation in the nervous system. With this loss, an individualâ&#x20AC;&#x2122;s balance and postural stability is likely impacted, leading to an altered quality of life. Monfort et al. at the Ohio State University are among the first to identify balance deficits in breast cancer patients during treatment, even after the first treatment cycle. We recently joined with them as they extended this work to include long-term follow-up testing after the completion of treatment. Our efforts specifically investigate postural stability, range of motion, and balance control while individuals stand on a force plate, looking at variances between individuals receiving different treatments and experiencing diverse outcomes. Preliminary data analysis from the limits of stability balance tests suggest there are differences between the three subject groups, with those not receiving neurotoxic chemotherapy showing the most consistent improvement 6 months after treatment. Breast cancer survivors that were treated with neurotoxic chemotherapy had varied individual responses 6 months post treatment. Further data analysis using traditional and alternative postural measures is currently underway to ascertain postural differences between the subject groups; however our results suggest that interventions to improve the postural stability of those treated with neurotoxic chemotherapy may be warranted.

Goal 3: Good Health and Well-Being STUDENTS Andy Lee Bazler, Bennett Clark Snyder ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The goal of this research is to design, build, and test new pedaling mechanisms to be incorporated into a bicycle-like devices for spinal-cord injured individuals. Many challenges arise in pedaling capability of a paraplegic or tetraplegic patient that are very different from a healthy individual. The intended tricycle users mainly employ Functional Electrical Stimulation (FES) to produce quadricep contractions, which are converted into a propelling force. Various concepts for alternative mechanisms have been produced. Pedaling force and motion simulation models were generated to evaluate the concepts. The desired pedaling mechanism must overcome dead-points encountered during the pedaling cycle while optimizing the transmission of power. Thus, the goal is to convert the modest amount of power generated by FESstimulated legs into cycling power for a tricycle.

Moving towards tuning of ankle-foot orthoses: The influence of carbon and plastic AFOs for individuals with Multiple Sclerosis School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Sarah Elizabeth Hollis ADVISORS Kim E Bigelow, Kurt J Jackson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Mobility impairments are reported as the most debilitating symptoms for individuals with Multiple Sclerosis (MS). Fatigue, a major symptom of MS, further affects mobility. Ankle-foot orthoses (AFOs) are one potential solution to alleviate some of these mobility impairments; however, the effectiveness of AFOs for individuals with MS are currently inconclusive and have known downfalls. We took a comprehensive look at both carbon fiber and polypropylene AFOs to gain an understanding of the immediate effects of AFOs for individuals with MS. In collaboration with the University of Daytonâ&#x20AC;&#x2122;s Doctorate of Physical Therapy Program, data was collected for 10 participants on various balance, gait, and strength/fatigue assessments. Overall, no significant differences existed between the baseline, carbon, or plastic AFO conditions for any assessment outcome (p>0.05); however trends did arise within the static and dynamic balance task results. Many outcome parameters varied among participants, suggesting the importance of individual responses to AFOs and patient preferences in prescribing AFOs. The majority of participants preferred the carbon AFO. All AFOs were off-the-shelf with only slight adjustments to account for fit and alleviate any pain, AFO tuning is believed to help optimize the efficiency of AFOs by adjusting the angle of the shank during midstance and the stiffness of the footplate. The next step in this work is to investigate the effects of AFO tuning in collaboration with area clinical partners. A case study is currently underway to give insight and better understanding to the effects of AFO tuning.

Maternal Depression, Child Temperament, and Risk for Depression in Adolescence: A Test of the Differential Susceptibility Hypothesis College of Arts and Sciences: Psychology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Karina H Palermo ADVISORS Jackson A Goodnight LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 This study examined the relationship between maternal depression, child temperament,and maternal parenting. Maternal depression has many effects on perceptions of andreactions to everyday interactions with the child (Belsky et al, 2007). Evidence has beenfound for depressed mothers reporting negative child behavior, while teachers reportpositive or neutral behavior in children of depressed mothers. Depression may skew amother’s understanding of her child’s behavior. On the other hand, a child’s difficulttemperament may be especially challenging for a depressed mother. The depression, incombination with child difficult temperament, may cause changes in parenting stylesthat put the child at a greater risk for depression. The purpose of this study was toexamine whether links between maternal depression and maternal parenting varyaccording to child difficult temperament. The identification of risk factors, such asdifficult temperament or maternal depression, is important when trying to developeffective intervention strategies. It was predicted that maternal depression would bemore strongly predictive of parenting deficits for mothers of children with a difficulttemperament. This study used previously collected longitudinal data from a nationallyrepresentative sample of mothers and their offspring. Maternal depression before thebirth of their child was measured using the CESD. Mothers reported on their children’stemperament between 1 and 23 months of age. Maternal parenting was assessed whenchildren were between 3 and 5 years of age using a combination of an interview andobserver ratings. Maternal depression showed a trend level association with decreasedresponsiveness (Beta = -.16, p = .076), and showed a significant association withincreased harsh parenting (Beta = .15, p = .047) and decreased learning stimulation(Beta = -.14, p = .002). Fussy temperament did not moderate associations betweenmaternal depression and parenting. These findings suggest that maternal depression is arisk factor for parenting characteristics that are associated with negative childoutcomes, but that difficult temperament does not affect these associations.

The effects of L. rhamnosus consumption on rat anxiety-like behavior College of Arts and Sciences: Psychology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Amanda Marie Schleper ADVISORS Tracy R Butler, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Adolescent stress in humans has been correlated with an increased likelihood of an adult individual to develop addictive behaviors, such as an alcohol use disorder. Literature has demonstrated that rats subjected to adolescent stress tend to show an increased ethanol consumption. Adolescence is a critical time of development and the link between adolescent stressors and alcohol use disorders is not fully understood yet. This study examined the relationship between adolescent stress and alcohol consumption in rats. Probiotics are bacteria with potential health benefits and have been well accepted as a dietary supplement. Literature shows that probiotics could decrease rodent anxiety-like behaviors derived from adolescent stress, such as social isolation. A previous study conducted at the University of Dayton showed that group housed rats that received probiotics exhibited increased anxiety-like behavior. This finding contradicts the positive perception associated with probiotics, showing that probiotics may have a negative impact on affective behaviors. Following two measures of anxiety-like behavior in rats, the Elevated Plus Maze and the Light/Dark Box, we did not find any significant differences between the chronically stressed and the control rats. Additionally, we did not find a difference between the groups in terms of alcohol consumption or preference. Lastly, this study did observe the same trend as our previous study in regards to the anxiety-like behavior demonstrated in the group housed probiotic group. We found that the group housed rats that consumed probiotics showed an increase in anxiety-like behavior. This trend did not include a significant difference between the groups, but was similar to what we observed previously. Moving forward, further research should be done to understand the potential benefits and risks of probiotics.

Narcissism consist of recurring patterns of grandiosity, constant need for admiration, and lack of empathy towards others. Students high in narcissism and egocentric self-views are have higher expectations of their academic performance in college, but these expectations may not necessarily correlate to actual academic performance. Previous research found that undergraduate students tend to exaggerate or inflate their grade point average (GPA). The current research examines the association between narcissism and academic exaggeration (reporting a higher GPA than their actual GPA), and subsequent academic performance. The current, longitudinal study recorded participantsâ&#x20AC;&#x2122; self-reported GPA and their official GPA at the start and end of the semester they participated in the study, as well as multiple measures of narcissism. It is predicted that the association between academic exaggeration and subsequent GPA will vary by narcissism, such that students with higher levels of narcissism who exaggerate their academic performance will have a lower subsequent GPA.

Differentiating Fall History in Older Adults Using Posturography School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Graduate Research Goal 3: Good Health and Well-Being STUDENTS Kyra Elizabeth Twohy ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union 310, 11:00-11:20 Background: Research findings are inconclusive if posturography is able to detect differences between older adults who fall and those who do not. This is likely due to differences in methodological choices in study design and reporting in posturography studies. Conducting a study including some of the factors previously found most useful may reveal larger and more consistent differences. Research Question: Can posturography differentiate fallers and non-fallers and is this differentiation improved when a definition of recurrent faller (2+ falls) and nonrecurrent fallers (0 or 1 fall) is used? Methods: 164 older adults, age 65 or older adults participated in this study. Participant were categorized as fallers (n=109) and non-fallers (n=55) and recurrent fallers (n=27) and non-recurrently fallers (n=137) based on number of falls reported in the past 12 months. Subjects completed a quiet-standing posturography assessment consisting of four testing conditions (eyes open or closed, and feet in a comfortable or narrow stance). Six traditional time-domain and two non-linear measures were calculated. Results: Significant between-group differences were found between fallers and non-fallers, with larger differences observed between recurrent fallers and non-recurrent fallers. The largest between-group difference was found when recurrent faller versus non-recurrent faller definition was used, in the eyes open narrow stance condition for ML Sway Range (p=0.002, effect size =0.96). Sample entropy did not differentiate in the groups in any condition or analysis. Significance: These findings suggest that posturography assessments can provide an efficient and accurate way to differentiate older adults based on fall history, if the right set of parameters is used when testing

Sex-differences in response to the antidepressant drug ketamine using a high fat diet model of metabolic stress College of Arts and Sciences: Biology Oral Presentation - Graduate Research Goal 3: Good Health and Well-Being STUDENTS Jenea Imani Adams, Lauren Cannatelli, John Richard Coffey, Claire C Cronin, Patrick Robert Flaherty, Matt L Jones, Benjamin Klocke, Katelyn Nicole Shea, Isaiah Taylor, Connor F Thelen ADVISORS Pothitos Pitychoutis LOCATION, TIME Kennedy Union 312, 11:20-11:40 A diet high in saturated fats has been known to induce metabolic stress that over time may lead to insulin resistance and eventually symptoms of type 2 diabetes. The development of these metabolic diseases is often comorbid with symptoms of depression and anxiety. Previously conducted studies have found that male rodents subjected to a high fat diet develop classic symptoms of anxiety and depression (e.g., behavioral despair, reduction in exploratory activity)which can be effectively treated with a single subanesthetic dose of the non-competitive N-methyl-D-aspartate receptor antagonist ketamine. Despite this, little is known about how a high fat diet regimen may affect the behavioral profile of female rodents, and if ketamine may reverse high fat diet-induced behavioral deficits. This study sought to assess basal behavioral sex differences in C57BL/6J mice exposed to a high fat diet regimen, and to assess whether ketamine may rescue depressive and/or anxietylike behaviors in a sex-dependent manner. Preliminary behavioral analysis in this project was conducted in the context of the experiential learning research component of the Fall 2018 Neurobiology Laboratory (BIO415L) class.

Factors Determining Stability in Older Adults Completing an Overhead Reaching Task School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Graduate Research Goal 3: Good Health and Well-Being STUDENTS Kyra Elizabeth Twohy ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union 310, 11:40-12:00 Reaching overhead is a challenging task, especially for older adults, specifically because many people adopt unstable stances that lead to falls. A study found that 99% of survey participants do reach for items over their heads and 43% reported a fear of falling when asked about the activity. This study aims to maximize stability in older adults by determining the best position to assume when completing this task. The effect of 3 factors on postural stability was investigated during an overhead forward reaching task: footwear (shoes on or off), stance (feet side by side or staggered), and foot contact (feet flat or heels lifted). Participants completed a total of 16 trials, 2 trials for each condition, each for 30 seconds. The trials measure the center of pressure in the Anterior-Posterior and Medial-Lateral directions by a force measuring platform. The average sway range in both directions, as well as mean velocity of the center of pressure were calculated. Results found that shoes on and feet flat on the floor decreased average sway ranges (90.6 mm vs. 38.1 mm), though an interaction between shoes and foot contact was found. Our findings led to a recommendation that older adults wishing to maximize stability have shoes on, and feet flat on the floor when reaching into cabinets.

The Relationship Between Childhood Trauma or Abuse and Suicidal Behaviors in Adults College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project Goal 3: Good Health and Well-Being STUDENTS Sami Marie Rossiter ADVISORS Leslie H Picca, Danielle C Rhubart LOCATION, TIME Kennedy Union 211, 11:40-12:00 Suicide rates rose nearly 30% between 1999 and 2016 where it is now in the top ten leading causes of death. Past research suggested an association between childhood trauma and suicidal behaviors later in life, however this association has not always been supported in recent studies. Using secondary data analysis, this project seeks to address the question: what is the relationship between childhood trauma/abuse and suicidal behaviors in adults? In this study, childhood abuse serves as the independent variable and suicidal behaviors or ideations as the dependent variable. The results indicate a significant relationship (p=.004) between the two variables, however the strength between them was weak. These findings suggest that there is a significant relationship between childhood abuse and suicidal behaviors, however further research needs to be conducted to fully understand the association and outside factors that may impact the data.

Antimicrobial Activity of Soil Isolates College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Sam Lee Neanover, Erica Marie Rinehart ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Antibiotics have historically been used for the treatment of bacterial infections and diseases, but the rise of antibiotic resistance has rendered many antibiotics ineffective against resistant bacteria. To combat these antibiotic resistant mechanisms, there is a demand for research in the development and production of new antibiotics. Antibiotics are either synthetically produced or isolated from bacteria displaying antimicrobial properties. Antimicrobial properties are observed in the environment as bacteria attempt to increase their fitness and eliminate competition for resources. As part of the Small World Initiative, this research aims to isolate bacteria from soil samples and screen for antimicrobial activity. Antimicrobial activity is detected by zones of inhibitions against Staphylococcus aureus and Enterococcus faecium, common antibiotic resistant pathogens. These zones of inhibition indicate if these pathogens are susceptible to antimicrobial activity. Bacteria that exhibit activity will be further screened for identification by Gram staining, catalase testing, and other biochemical tests. Identifying bacteria displaying antimicrobial activity is important for addressing the antibiotic resistance crisis and contributing toward the development of new antibiotics.

UN SUSTAINABLE DEVELOPMENT GOALS

Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Kaylin Ann Kultgen ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Throughout this past semester, I have been doing research in BIO 411L (Microbiology Lab) using procedures established by the Small World Initiative. The goal of the research is to isolate bacteria that displays anti-microbial effects on known pathogens. This research could potentially be used to help create new antibiotics to fight against human pathogens. A dirt sample was collected from the side of my house in the UD south student neighborhood. Colonies of bacteria formed on TH and TSA plates. Ten colonies were chosen from each of these types of agar plates. The colonies were plated on dishes streaked with the known pathogens, Pseudomonas aeruginosa and Enterococcus faecium, then later Klebsiella pneumoniae, and Staphylococcus aureus. The colonies that formed zones of inhibition were isolated and further testing was done to determine the species and characteristics of the bacteria. Some of these tests included a gram stain, catalase test, and various other biochemical tests to determine characteristics of the antibiotic producing bacteria. Later this semester, I will perform a chemical extraction for the metabolites of the chosen bacteria as well as observe the interaction between the extract and eukaryotic cells.

Inhibition of Pseudomonas aeruginosa Biofilm Growth using TMP preventative treatment on Steel and Polyethylene substrata College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Erin Elise Pellot ADVISORS Karolyn M Hansen, Nehaben Nik Patel LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Within recent years there have been a growing number of antibiotic resistant bacterial strains. Many of these strains produce biofilms, which are sturdy layers of bacteria on a surface. These biofilms are highly antibiotic resistant and have multiple defense mechanisms. Biofilms have been known to form layers on metal implants after surgery and dialysis tubing which can prevent typical antibiotic treatment methods from being effective. In order to prevent biofilms from forming on steel and polyethylene coupons the porphyrin Tetramesitylporphyrin (TMP) was tested as a pre-treatment for Pseudomonas aeruginosa, one of the six ESKAPE bacterial pathogens responsible for most deadly opportunistic infections in the United States. In this experiment steel and polyethylene coupons were placed in a 225 µM TMP and a 100 µM TMP solution for time periods of three and five hours. After this presoak period the coupons were submerged in a PAO1 liquid culture for an 18-hour period. Once a biofilm was formed the coupons were removed and vortexed in sterile water to resuspend the biofilm. A serial dilution and plating was then carried out and the plates were placed in the 37°C incubator overnight. A Colony forming unit (CFU) count was taken the next day to asses the log reduction created by TMP pretreatment. Results showed a roughly .5 log reduction in the 100 µM TMP and 225 µM TMP treatment trials.

Community Assessment of Twin Towers, Dayton, Ohio: Dietary-Related Psychosocial and Cultural Factors School of Education and Health Sciences: Health and Sport Science Poster - Course Project, 201910 HSS 302 01 Goal 3: Good Health and Well-Being STUDENTS Carolyn A Botti, Alyssa Kate Hrobat, Liana Laurette Sans, Tori Lucienne Sedlmayer ADVISORS Diana Cuy Castellanos LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The Twin Towers is a low-income neighborhood in southeast Dayton and has a high prevalence of overweight and obese residents. The main objective for this assessment was to determine the dietary-related psychosocial and cultural factors that affect the dietary intake patterns of people residing in this neighborhood. Values, beliefs, social norms, tradition, taste preferences, and self-efficacy were analyzed within the community through a questionnaire distributed at the East End Community Center, along with various secondary peer-reviewed sources. It was found that nutrition knowledge was not the main barrier to a healthy diet, but self-efficacy, taste preference and lack of cooking tools and skills contributed to an inadequate diet. This data collection allowed the development of an intervention to implement within the community in order to improve the diet quality of people residing in this neighborhood. Due to these identified barriers, we suggest interventions regarding self-efficacy and the implementation of nutrition-related skills.

UN SUSTAINABLE DEVELOPMENT GOALS

School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Independent Research Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Luke Hoover, Brad Raymond Hripko ADVISORS Robert L Lowe, Timothy Reissman LOCATION, TIME Kennedy Union 211, 1:20-1:40 Additive manufacturing (AM) is a potentially game-changing manufacturing technology capable of rapidly and inexpensively fabricating complex part geometries unattainable with conventional “subtractive” manufacturing techniques. Attention within the AM community has gradually shifted from rapid prototyping to the fabrication of load-bearing components. Toward that end, this talk focuses on the processingproperty-performance relationship in a FDM 3D-printed polyurethane elastomer, NinjaFlex. Nominally, NinjaFlex is capable of elongations greater than 650%, making it appealing for load-bearing biomedical, automotive, and aerospace applications requiring large elastic deformations and extreme stretchability. ASTM D412 tensile test specimens are 3D printed using a Josef Prusa I3 MK3 FDM printer (under different processing conditions) and mechanically tested using an Instron 3365 long-travel load frame. Several common hyperelastic material models (e.g., neo Hookean, Mooney-Rivlin, Yeoh, Ogden, Arruda-Boyce) are calibrated to the mechanical test data and implemented into the commercial finite-element software Abaqus. Preliminary finite-element simulations are conducted on a 3D-printed NinjaFlex prosthetic finger geometry to quantify the impact of manufacturing process parameters on prosthetic performance.

Bubble-in-a-Droplet Based Surface Enhance Raman Scattering Substrate for Ultra-sensitive Chemical and Biosensing School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

Goal 3: Good Health and Well-Being Goal 9: Industry, Innovation, and Infrastructure STUDENTS Farzia Karim ADVISORS Chenglong Zhao LOCATION, TIME Science Center 62, 1:45-2:00 In this work, a cost-effective and ultra-sensitive chemical and bio-sensing platform has been developed for rapid identification of pathogens or hazardous chemicals. Fast and accurate detection of pathogens or toxic chemicals is an urgent need for several medical and industrial purposes. For example, in the food industry, it is an extremely important matter to detect food-borne pathogens or harmful food chemicals and then efficiently eliminate contaminated sources from production chain to protect people from toxic food-borne infections and thereby ensure food safety. In addition, due to the increasing population of the present world, existing food production needs to be increased and it is essential to develop ways to provide safe food free from pathogenic or chemical contamination. Conventional methods to detect pathogens are usually time consuming, labor-extensive and expensive. This work demonstrates a time-efficient, labor-saving and affordable way to rapidly detect pathogens and injurious chemicals for the prevention of food-borne diseases. This method works based on laser induced heating of metallic nanoparticles which generates a bubble inside a nano-liter size droplet of nanoparticles solution. Nano-liter size droplet reduces sample consumption and contamination. Bubble creates a strong Marangoni convective flow to rapidly deposit nanoparticles on substrate to fabricate a nanogap rich plasmonic structure that acts as a surface enhance Raman scattering (SERS) substrate. Liquid solutions containing toxic food chemicals or pathogens are attached on SERS substrate. SERS provides finger prints of specific pathogen or chemical through Raman spectroscopy which allows a label-free detection and discrimination of multiple pathogens or harmful chemicals. Optothermal bubble not only offers rapid fabrication of SERS substrate but also helps to locally increase the concentration of pathogens or chemicals attached on SERS to improve sensitivity of chemical and biosensing platform. This work offers an affordable, rapid and ultra-sensitive detection method for efficient chemical and bio-sensing application.

More specifically, an experiment was designed to test story-based messages as stigma reduction strategy. The story focuses on a university freshman struggling in a non-major course. The student admits feeling anxious about the situation but does not want anyone to know about it. Participants are randomly assigned to view one of three versions of the story: 1) a single perspective, 2) the same story told from two perspectives

(highlighting normalization of mental health struggles), or a no exposure control. The impact of the stories on the mental health outcomes of interest provide insights for stigma-reduction strategies.

Investigation of Spontaneous Emission GeSn for thin film alloys School of Engineering: Electro-Optics and Photonics Oral Presentation - Independent Research

Goal 3: Good Health and Well-Being Goal 9: Industry, Innovation, and Infrastructure STUDENTS Elaheh Ghanati ADVISORS Imad Agha, Jay Mathews LOCATION, TIME Science Center 62, 2:45-3:00 Si is the material of choice for making microelectronics, and it is the building block of a $400bn industry. While silicon has reasonable electrical characteristics, its optical properties do not make it the best choice for photonics. The band gap does not allow for absorption in the 1.2-2 um range and the indirect band gap means that no lasers can be produced from silicon.A silicon compatible material which responds actively and efficiently to light, with the ability to emit or receive in the infrared region, could be used to achieve infrared photonic devices on silicon. Ge is a promising candidate due to its lower band gap and its ability for direct band gap emission. It has been reported that alloying Ge with Sn helps to change the band structure of Ge by lowering the band gap and increasing the efficiency of optical absorption and emission. Thus, GeSn alloys represent a class of materials with a tunable band gap for building photonic devices like photodetectors, LEDs, and even lasers for a variety of applications. In this work, we explore the tunability of optical emission by measuring photoluminescence from GeSn thin films with varying concentrations of Sn.

The Correlation Between the Purchase and Use of Fake IDâ&#x20AC;&#x2122;s in a College Environment and Its Potential to Lead to an Alcohol Addiction College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project Goal 3: Good Health and Well-Being STUDENTS John P Canning, Corky Elizabeth Hart ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union 211, 2:20-2:40 What are reasons for purchasing a fake IDs? How does possession of it lead to excessive and perhaps addictive drinking behavior among college students? Through this research project, we aim to identify the costs and effects of the purchase and use of fake IDs on alcohol addiction. We utilized a mixed methods approach to study the relationship between fake ids and alcohol addiction. The results from a survey of college students and background information provided from interviews with professionals on fake IDs (Local and Federal Law Enforcement officers, bouncers) are presented.

UD ETHOS 3D-Printed Soft Prosthetic Fingers

School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Capstone Project Goal 3: Good Health and Well-Being STUDENTS Michelle J Molskow, Khyel David Tolliver, Andrew Edward Zarlinski ADVISORS John B Hageman, Robert L Lowe, Timothy Reissman LOCATION, TIME Kennedy Union 222, 2:40-3:00 3D printing has become one of the leading advances in technology when it comes to efficiently manufacturing parts while remaining cost effective. This especially holds true in the field of prosthetics. The advancement in medical technology, namely prosthetics, through 3D printing has increased the capability of those parts becoming more customizable for the benefit of the patient. Statistically, 2.4 million of the 3 million people worldwide living with an arm amputation live in developing countries. Unfortunately, most prosthetic devices are designed for insurance-subsidized markets, rendering the prosthetics unaffordable to the majority of the aforementioned countries. Philanthropic companies such as e-NABLE and the Open Hand Project have made extensive efforts to develop 3D printed prosthetic hands at an affordable price; however, the majority of all prosthetics that are 3D-printed are manufactured from relatively rigid thermoplastics such as ABS or PLA which limit conformability and compromise patient comfort. This is where our team seeks to find an alternative solution, one that allows for a patient to have a fully functioning prosthetic finger without compromising their comfort through the use of elastomeric 3D printed material.

We are looking at three different dimensions in our project to analyze the significance of substance use. The three dimensions are the culture of being in the military, deployment history, and the stigma surrounding military service members.

Growth Regulatory Pathway collaborates with Axial Patterning Genes to regulate Patterning and Growth in Drosophila Eye College of Arts and Sciences: Biology Oral Presentation - Graduate Research Goal 3: Good Health and Well-Being STUDENTS Neha Gogia, Akanksha Raj ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union 311, 3:00-3:20 An important question in developmental biology is how any three-dimensional organ develops from single monolayer sheet of cells. In any multicellular organism, organogenesis requires axial patterning to determine Antero-Posterior (AP), Dorso-Ventral (DV), and Proximo-Distal (PD) axes. Any deviation in these axes during development leads to congenital birth defects. We have used Drosophila melanogaster (a.k.a fruit fly), eye as our model organ (as genetic machinery is conserved between flies and humans), and have identified defective proventriculus (dve-a Homeobox gene), vertebrate ortholog of SATB1 (special AT-rich sequence binding protein 1 in humans), as a new member of DV patterning genes hierarchy. We have shown, that (1) dve acts downstream of pannier (pnr, a GATA-1 transcription factor), and upstream of wingless (wg), (2) Loss-of-function (LOF) of dve or pnr results in dramatic dorsal eye enlargements, while their Gain-of-function (GOF) suppresses the eye specific fate, (3) Furthermore, Wingless (Wg) is a downstream target of Hippo pathway (highly conserved) and wg, (acts downstream of dve), also exhibits similar eye enlargement and suppression phenotypes (upon LOF, GOF respectively) and has been known to play an important role in growth. Here, we present that DV patterning genes interacts with Hippo signaling to regulate their common downstream target, Wg during growth and patterning in the developing eye. We found that these two unrelated pathways act antagonistically to each other. Furthermore, activation of Hippo signaling suppresses dve or pnr expressing cells, which downregulates Wg and changes head, antennae specific fate to an eye. Additionally gain-of-function of dve or SATB1 in eye leads to similar Wg upregulation and eye suppression phenotypes. Since gain-of-function of hippo triggers cell death, we tested if by blocking cell death by using p35 exhibits similar phenotypes. However, we found that hpo GOF phenotype in dve domain is not due to blocking cell death but by regulating retinal differentiation. We present a model where growth regulatory pathway regulates axial (DV) patterning genes expression in the developing eye of Drosophila. These studies present new genetic interaction between two unrelated pathways and have significant bearing on developmental mechanisms.

Electronic Addiction and Mental Health

College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project Goal 3: Good Health and Well-Being STUDENTS Sam Anthony Carter, Emily Sue Jones, Kara Lynnette Warren ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union 211, 3:40-4:00 We are researching the effect that electronic addiction has on mental health by conducting a survey. The survey will consist of many different questions related to mental health (anxiety and depression) and participant dependence on electronic devices. The survey will be sent out through social media and snowball sampling. We predict that the more dependent students are on their electronic devices the more prominent mental health issues will be. We suspect that 18-24 year old individuals will have the highest rates of addiction along with the most mental health issues. The results from our survey will be presented.

Asset Size, Asset Growth, and Stock Returns; an Empirical Analysis, 2008-2017 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education

UN SUSTAINABLE DEVELOPMENT GOALS

STUDENTS John Martin Harmon ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In this study, I consider two important strategic investment issues: (1) firms size matters and (2) asset growth is a predictor of returns in the cross section. Empirically, I test two hypotheses: (1) Small firms outperform larger firms over long periods of time and (2) firms with the highest asset growth rates underperform firms with low asset growth rates over long periods of time.Both of the above hypotheses have been tested in previous academic studies but not for the period 2008-2017. This period includes a major economic and market recession in 2008 followed by a major market expansion continuing through 2017. With this bull market, however, market returns are uneven, with a flatter trading range year in 2011 and a down market year in 2015. As a result, I will also be able to see the effects of return variability on the asset size and asset growth portfolios.Following the approach taken by Eugene Fama and James Macbeth1, I compare the performance of large size firms to small size firms over the period 2008-2017. Using the 500 stocks included in the S&P 500 index as my sample universe. I develop portfolios of stocks based on asset size and use two investment strategies to make the performance comparisons: (1) Buy and Hold and (2) Rebalance (annually). To test the 2nd hypothesis, I follow the approach used by Michael Cooper et. al.2 and calculate asset growth rates for all S&P 500 stocks on a yearly basis from 2008-2017. Firms are sorted by asset growth rates, high to low, and placed in portfolios of 50 stocks each. The highest growth rate portfolio and the lowest growth rate portfolio returns are then compared on an annual and cumulative basis using buy and hold and portfolio rebalancing strategies. Return comparisons are also made against SPY, the S&P 500 SPDR ETF. Finally, using the information ratio, risk adjusted returns will be calculated for the asset size and growth portfolios to determine which portfolio models have the best risk-return outcomes.

A Smart Beta Concentrated Portfolio Model for the Information Technology Sector: An Empirical Analysis, 2009-2017 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Jacob James Willmann ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Smart beta models are essentially factor weighting models with a focus on fundamental based stock weights (FBSW). A growing number of investment managers are now using them to generate increased alpha over their performance benchmarks. In this study I use a two factor weighting model for 10 and 20 stock concentrated portfolios in the S&P 500 Information Technology Sector ETF (XLK). I use sales growth and relative price change as my weighting factors and test two hypotheses: (1) FBSW models will outperform the broad market (S&P 500) over long periods of time and (2) FBSW models will outperform their sector counterpart over long periods of time. The period of analysis is 2009-2017.

A Comparative Analysis of Rules Based Versus Passive Index Portfolio Returns (2009-2017) School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Brendan James McDonnell ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Rules based portfolios of stocks, often referred to as Smart Beta or Quant based portfolios, are increasingly being used by investment managers to enhance portfolio performance. In this study, I develop a fundamentals base 2 factor portfolio weighting model for 10 and 20 stock (concentrated) Portfolios in the S&P 500 Healthcare sector (XLV). I compare the the returns for these concentrated portfolios to the returns for the S&P 500 Index, ETF SPY, and the SPDR Healthcare Sector ETF, XLV. My sector weights are sales growth and relative price change, and the period of analysis is 2009-2017. I test the hypothesis that a rules based portfolio of stocks will outperform a broad based passive index (SPY) and its sector counterpart (XLV).

pre-2008 trend regressions were higher than the slope coefficients for the post-2008 regressions. I also forecast wage growth for 2018 using the univariate regression models adjusted for root mean square forecasting error (RMSE).

Money Supply Growth and Inflation Trends Post 2008 Recession: A Closer Look at the PCE Inflation Index School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Reed Thomas Aleck ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 After the 2008 recession, the Federal Reserve initiated an aggressive policy of monetary easing. In this study, I examine the relationship between money supply growth and inflation using Personal Consumption Expenditures (PCE-All) as my measure of inflation. I develop univariate regression models with M1, M2, and MZM as the independent variables and PCE-All as the dependent variable. I test the hypothesis that the slope coefficients are positive and statistically significant (T-Stats > 2). I also forecast 2018 PCE-All inflation rates to determine the forecasting accuracy of the models. My forecasts also take into account the root mean square forecasting error (RMSE).

Fundamentals Based Stock Weighting for Concentrated Portfolios in the Industrials Sector: An Empirical Analysis, 2009â&#x20AC;&#x201C;2017 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Will Luis Perez ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 More and more Exchange Traded Funds (ETFâ&#x20AC;&#x2122;s) are using fundamentals based factor weighting (FBFW) to enhance performance and generate alpha. In this study I develop a two factor weighting model for a concentrated portfolio of 10 and 20 stocks in the S&P500 Industrial Sector ETF XLI. I use sales growth and relative price change as my weighting factors and test two hypotheses (1) Concentrated stock portfolios with FBFW models can outperform the broad market over long periods of time and (2) Concentrated stock portfolios with FBFW models can outperform their market weighted sector counterparts over long periods of time. The period of analysis is 2009-2017.

U.S. Inflation Trends after the 2008 Recession; An Empirical Analysis of CPI - All School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Kathryn R Schulz ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 A key variable in determining U.S. Federal Reserve Policy concerning Fed Funds Rates is the inflation rate in the U.S. economy. In this study, I developed time trend models for each month of the year using 2009 - 2017 as my modeling period. I then used the twelve time trend regression equations to forecast inflation levels for each month in 2018. Adjusting the forecast using the root mean square forecasting error procedure, I test for forecasting accuracy based on an error tolerance of 2%.

A comparison of Pre and Post 2008 inflation trends for the consumer Price Index (CPI) Less Food and Energy: An Empirical Analysis 1999–2018 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Christian Gerard Hense ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Despite an aggressive policy of Monetary easing by the Federal Reserve. Inflation seems to be rather benign after the 2008 recession. In this study I compare inflation trends before and after the 2008 recession to determine if the long term inflation trend has significantly changed due to the 2008 economic rescission. I use the inflation metric CPI -Less Food and Energy because it is a measurable, less volatile measure of inflation. I also forecast CPI (LF&E) for 2018 using Linear Trend regressions adjusted for a root mean square error (RMSE). I use an error tolerance of 2% to determine forecasting accuracy.

Impact of Classroom Quality and Preschool Experiences on Executive Functioning College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education STUDENTS Shelbie Nicole Weightman ADVISORS Mary Fuhs LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 From a young age, executive functioning begins to develop in children. Executive functions are a group of cognitive processes that are important for processing speed, working memory, inhibition, and cognitive flexibility. These skills typically begin to develop drastically around the time children are entering the preschool years. However, research has shown that poverty can negatively impact the development of executive functioning due to the lack of resources available. There is evidence that chronic exposure to poverty and chronic exposure to certain psychological stressors related to poverty can predict children’s executive functioning at four years-old (Raver, Blair, & Willoughby, 2013). On average, children who are poor have much lower starting points and cognitive growth slopes later on throughout childhood (Raffington, Prindle, & Shing, 2018). I am interested in strategies that can combat this issue and reduce the gap in executive functioning skills between children from different family incomes. A high-quality, teacher-child interaction involving classroom organization and emotional support has been shown to have a great impact (Choi, Castle, Williamson, Young,Worley, Long, & Horm, 2016). Along with this, incorporating mindfulness-based prosocial skills curriculum into the early ages of education has also shown to help close the gap in executive functioning, as well as social-emotional development (Flook, Goldberg, Pinger, & Davidson, 2014). In both of these strategies, the children from low-income backgrounds had the largest gains. We will investigate the correlations between higher quality elements of the classroom environment and preschoolers’ growth in executive functioning skills. Data will come from a large-scale longitudinal study of preschool school readiness skills development.

The Effect of Poverty on Special Education Outcomes in Ohio School Districts College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project Goal 4: Quality Education Goal 10: Reduced Inequalities STUDENTS Theresa Erin Finan ADVISORS Leslie H Picca LOCATION, TIME Kennedy Union 211, 9:20-9:40 Making sure that all children receive a quality education is essential to the health of a society. Individuals with special needs who are also living in poverty face difficulty in the educational system today. The purpose of this study was to look at how being at or below the poverty line impacts Special Education outcomes regarding proficiency in reading and math. Secondary data analysis of data retrieved from the Ohio Department of Education and the American Community Survey was used to determine the relationship between the two variables of poverty and Special Education outcomes. The results found that poverty was significantly related to school districts not meeting the standard for

We will illustrate the difference between historical knowledge and historical literacy by presenting our research on methods of teaching designed to increase historical thinking skills. Several practices that teachers should employ to teach students how to analyze historical texts using historical literacy methods will be discussed, including sourcing, close reading, corroboration, and contextualization. Having read deeply into the historiography of the Irish Famine, and after examining the famine curricula in New York and New Jersey, we will discuss how sources such as memoirs, folklore, newspaper, and government documents provide valuable insight into the heuristics that historians use when constructing a historical narrative. High school students should begin to understand and develop these heuristics after a thorough examination of the primary and secondary sources used throughout school texts and curricula facilitated by critical discussion and guidance from the teacher; we will specifically target the epistemic stance and cognitive meta-concepts used by historians.

The Relationship Between Growth Mindset and Students’ Psychological Well-Being School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research Goal 4: Quality Education STUDENTS Kelly Marie Berlin ADVISORS Elana Renee Bernstein LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Research suggests that adopting a growth mindset can have positive implications for students’ academic outcomes, adjustment, academic emotions, and motivation. Having a growth mindset is also positively associated with resilience, which is positively associated with psychological well-being. The present study examined the relationship between high school students’ self-reported levels of growth mindset and psychological well-being. Results of a survey given to (n = 85) high school students demonstrated no significant relationship between students’ overall levels of growth mindset andpsychological well-being. Further, results indicated that no significant relationship existed between growth mindset and any individual domain of psychological well-being (i.e., autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance). Implications for practice and future research in the area of growth mindset are provided.

A Cross-national Study of Whole Number Addition and Subtraction College of Arts and Sciences: Mathematics Poster - Independent Research Goal 4: Quality Education

UN SUSTAINABLE DEVELOPMENT GOALS

STUDENTS Mary Margaret Ghiloni ADVISORS Rebecca J Krakowski LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 While mathematical fluency is of great value in everyday life, in a changing world where information is easily accessible to students, problem solving skills and deep understanding of why math works over how it works is of more value and can be applied to both mathematical and non mathematical situations. When students move on from formal schooling and take their place in the “real world,” they will excel when they have the skills to create new ideas, evaluate new and existing ideas, and defend their own will allow students to effectively analyze the world around them. This study examines 1st-3rd grade textbooks from Singapore, Finland and the United States in an effort to pinpoint how these countries develop mathematical concepts. In particular, this study looks at whole number addition, subtraction by analyzing textbook problems, how they utilize different representations, algorithms and cognitive levels. This study increases our understanding of how math is being taught in different countries and how this might contribute to disparities in international test results.

In 2017, volunteers at Reach Out logged 9,585 hours in service of the uninsured (2017 Annual Report 3). In order for the clinic to run efficiently, volunteers should be confident in their ability to triage, take vitals, and document all information. However, there is no concrete training plan currently put into place, so new volunteers are often thrown into the clinic setting and expected to learn as they go. This method creates a volunteer with an inconsistent and often incomplete knowledge of how the clinic operates and may lead to certain aspects of the patient’s visit that are overlooked or taken care of incorrectly. It is our goal to better prepare incoming volunteers for the expectations of the clinic so they can maintain a high quality of care for the patients. We will do this by promoting a system where new volunteers shadow an experienced individual to learn the proper techniques of triaging and taking vitals. We will also supplement this by creating a laminated resource sheet volunteers can keep with them for quick access to any of the information or techniques they have learned. This poster will summarize the training method and the techniques the volunteers will learn along with laying out the resource sheet we will be designing for Reach Out’s use.

Sleeping on “it” DOES work: Memory for pictures becomes stronger the day after learning, even with an interruption in the learning task College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education STUDENTS Victoria Lynne Karpuszka, Sarah Phoebe Lawson, Madeline Margaret Nash, Alicia Michelle Selvey, Gabriella Louise Silone, Carolina Sofia Vazquez ADVISORS Susan T Davis LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Research indicates that memories are strengthened by consolidation, the incorporation during sleep into a previously established memory network (Rasch & Born, 2008; 2013). Memories are initially unstable after encoding and sleep consolidation increases resistance to interference (Robertson, 2011). On the first day of a two-day experiment designed to examine whether an encoding task interruption and a delay in retrieval would affect later memory consolidation, participants memorized pictures of common objects (e.g., owl) presented in a slideshow. Participants were assigned to complete either an immediate recognition test that included studied and unstudied pictures (“lures”), or return the following day to complete a delayed recognition test. Some were assigned to be tested on the two consecutive days. There were three hypotheses: (a) target pictures tested for memory only on the second day would be remembered as good if not better, due to sleep consolidation, than when tested for memory only on the first day; (b) there would be serial position effects on sleep consolidation of the target pictures due to the task interruption, such that recency before interruption would be reduced while other serial position effects would be stable; (c) pictures tested on both days would be better remembered on the second day than on the first. A 3 (Test day: Day 1, Day 2 or both days) x 2 (Test stimulus: Targets and Lures) ANOVA compared correct discrimination for each condition. The interaction between stimuli and testing day was significant and strong (p = .001, η2 = .189), indicating that participants tested on Day 2 were as correct as those on Day 1 in identifying picture targets. However, although participants on Day 2 remembered more targets, they also incorrectly remembered more

lures than on Day 1. Sleep consolidation has an overall effect of maintaining the strength of “real” memories over time.

In Addition to Improving Memory for Paintings, Self-generation of Elaborative Titles Increases Aesthetic Preferences College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education STUDENTS Terah Lee Blakemore, Chloe Michelle Clark, Abigail T Flower, Tessa Nicole Jatczak, Hannah M Propes, Rachel Marie Yeager, Yu Zhao ADVISORS Susan T Davis LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Aesthetic preferences are influenced by factors such as context surrounding art (e.g., titled photographs; Millis, 2001). In addition, selfgeneration of context information influences the strength of memory, in general. The present study examined the influence of titles that are participant-generated on aesthetic preferences and memory for paintings. For each painting, there were two types of titles generated: elaborative (evoking a deeper thought process, such as “Water Sustains Life” for a painting of a bridge over a stream) or descriptive (naming objects in the painting, such as “Bridge over Water.” All participants were first exposed to paintings without titles. Participants were then exposed to the same paintings in a different order and generated their own titles consistent with either elaborative or descriptive titling instructions and were asked questions assessing preferences: if they liked the painting, if they would buy the painting, and if they would hang the painting in their home. Control participants also rated the paintings, without the titles and without generating titles. After the ratings, all participants completed a task to distract from rehearsing memory for the paintings, and then viewed the original paintings intermingled with paintings not seen earlier to test their memory for the original paintings. We hypothesized that participants would exhibit greater preferences and better memory for paintings with self-generated elaborative titles than for those with self-generated descriptive or no titles. Our earlier research found that preference and memory were stronger for the paintings with elaborative and descriptive titles than for those with no titles. However, memory and confidence in the accuracy of memory was stronger for paintings with descriptive than for those with elaborative or no titles. The results of the present experiment suggest that the deeper cognitive processing of self-generated elaboration enhances an aesthetic experience when viewing paintings and makes the paintings more memorable.

Truth or Lie: Applying Indirect Methods to Detect Deception College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education STUDENTS Jacob Severino Avendano, Kelly Catherine Boris, Colin L Lamb, Cara Jane Miller, Shelbie Nicole Weightman ADVISORS Susan T Davis LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The ability to detect deception accurately has been found to be 54%, which is only a slightly better judgment than predicting the outcome of a coin flip (Bond & DePaulo, 2006). Fortunately, more recent research conducted by ten Brinke et al. (2016) indicates that indirect methods may better produce detection of deception than do direct methods. These research results have inspired our team to study indirect and direct questions further to better understand the underlying causes for the success of indirect questioning. Consequently, the present research utilized different types of indirect questions to better determine if someone is being deceptive. These questions were based on the role of biases, individual personality characteristics, and expected behaviors,-verbal and nonverbal-, all believed to be associated with deception. Answers from a control group of observers asked direct questions about whether an interviewee in a video was lying about previous behavior were compared with answers from an experimental group of observers asked indirect questions. Two research hypotheses about the outcome of this manipulation are: (a) indirect questioning of an interviewee’s dishonest responses would produce more accurate determinations of dishonesty than direct questioning, and (b) questions designed to detect bias about or expectations of dishonest behavior would be more accurately related to the dishonesty of the interviewee in the video than those questions related to interviewee verbal and nonverbal characteristics. Data collected thus far indicate that indirect questions, as a group, are consistently better at detecting deception. The next steps in our analyses are, first, to analyze the different types of indirect questions (biases, characteristics, and expected behavior) to better understand which indirect questions are more reliable in detecting deception, and second, to assess any interactive effect of participants’ gender with the gender of the interviewee in the videos on detection results.

Impact of Parental Involvement in the use of Adaptive eBook Technology on Preschoolers’ Math Skills College of Arts and Sciences: Psychology Poster - Independent Research

UN SUSTAINABLE DEVELOPMENT GOALS

Goal 4: Quality Education Goal 10: Reduced Inequalities STUDENTS Patrick Caleb Ehrman ADVISORS Mary Fuhs LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 By the time students in the United States reach the fourth grade, the majority do not perform at or above the level of proficiency in mathematics (National Assessment of Educational Progress, 2017). A child’s education in mathematics begins at a very young age. One method by which children are introduced to the basic concepts of math is number books. Traditional number books have been found to be successful in promoting mathematical knowledge, but are stagnant in their difficulty, leaving parents to discern ambiguously when their child is ready to move onto more difficult problem-solving (Elia, Heuvel-Panhuizen & Georgiou, 2010). The present study seeks to discern the effectiveness of new eBook technology, as well as the impact parents have on their children’s ability to learn. Specifically, does a discrepancy in the magnitude of the pictures in counting books lead to better learning and does the eBook facilitate learning that overcomes a parent’s anxieties in math. Two different eBooks will be read to thirty randomly selected parent-child pairs at the Dayton Metro Library during their summer Family Story Time sessions. Children will be ages 3-5. A survey will be used post reading to measure the parents’ predisposition towards liking or disliking math, as well as their current methods of math instruction in the home. The results of this study will be assessed using a paired samples t-test. This study predicts that the eBook containing discrepancies in image magnitude will facilitate higher quantity and quality of math-based discourse between parent and child. Additionally, the eBook formatting will help combat the impact a parent’s math anxiety has on their child.

School Choice

School of Education and Health Sciences: Teacher Education Poster - Course Project, 201910 EDT 110 H1 Goal 4: Quality Education STUDENTS Madison Johanna Spicuzza, Emily M Sreenan ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 One recent topic of controversy in the United States is the idea of “school choice” and whether the benefits of giving families the ability to choose any type of school truly outweighs the drawbacks. Financial stratification within school choice leads to lower income families and minority groups being limited in their choices, even if a child may benefit from a different type of school or type of education specifically. This project outlines the academic benefits and drawbacks, as well as the financial implications for families desiring to utilize school choice. It also examines Montessori education as an example of one option in school choice. Specifics of this type of schooling will be identified, such as the emotional benefits of having it as a choice for many students who would thrive under the individualized environment. However, the financial costs and demographics are also included to shed light on the possible discrimination of the choice system. Using Montessori education as an example aims to demonstrate the possible controversy regarding the idea of school choice, and whether there truly is a choice for all.

Technology in the Classroom

There are benefits and risks that come with using one to one technology, online textbooks, and online classrooms that can have varied impacts on student learning and development. One to one technology, including its implementation, can influence student-teacher relationships and the overall effectiveness of technology in the classroom. Online resources, especially textbooks, have proven to be controversial tools for students. Some students complain about eye strain and the need to print online texts in order to learn, while others appreciated the decreased price tag of online resources. Studies show that online learning can contribute to feelings of isolation and a lack of belonging as students are unable to develop the same tactile relationships with teachers and other students as is possible in a traditional classroom. As society moves away from traditional classroom learning and increasingly relies on technology, the effects of online learning and resources must be examined in order to ensure a quality education for each student.

In this presentation, we will explore how the brain learns, stores, and retrieves language, as well as the specific differences between the brain’s activity when learning a first and additional languages. The brain as related to language is complex and is not yet fully understood; however, this presentation will discuss the accepted theories about the brain structures and function connected to language. These theories will describe the processes that learn, store, and retrieve language in the brain. Although there are still discoveries to be made, research has shown that differences exist between learning a first and additional languages. These may include the ease of learning the language, how hard one’s brain must work when processing first and other languages, and even the visibly noticeable effects between using a first or other language. With the former information in mind, we will explain how the neurological structures and processes of language and the differences in brain function that occur while learning a second language as opposed to the first can be used to impact teaching styles for language acquisition.

School Funding and Extracurricular Activities

School of Education and Health Sciences: Teacher Education Poster - Course Project, 201910 EDT 110 H1 Goal 4: Quality Education STUDENTS Andrew Michael Buchanan, Maria Christine DiFranco ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 This poster describes the benefits of performing arts in students’ academics, as well as school funding policies that affect the overall success of students. Differences in funding by district and state are explored and how the unequal distribution contributes to school inequality. With the performing arts often being ignored, the importance of funding students’ artistic endeavors is explored, as well as how the performing arts increases students’ academic performance. The performing arts can benefit children in multiple different ways. One way is the use of theatre inside the classroom. Studies have shown that by integrating the arts in other subjects, students’ interest in school increases, and so their performance also benefits. The arts have been shown to increase language skills and interpersonal skills, which help underprivileged kids especially since often they are behind in these rudimentary skills. These skills do not have to be learned in a classroom, however, and can be learned if students participate in the performing arts outside of school as well. These theatre experiences show benefits such as cooperative skills and can be used in any grade. They should not be ignored in early childhood classes, but more frequently have been shown to decline in schools.

Work vs Play in classrooms

School of Education and Health Sciences: Teacher Education Poster - Course Project, 201910 EDT 110 H1 Goal 4: Quality Education STUDENTS Hailee M Cain, Katelyn Marie Gillotti ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 We will be exploring the benefits of play in early childhood classrooms and beyond. Research shows that there are significant benefits to play, but recently school systems have begun to phase out the importance of play in their curriculums. Instead increasing academic rigor has taken over the life of the everyday classroom. While academic skills are vital, social skills are equally as important for student’s proper development. Teachers and educators of all grade levels must find methods to incorporate both cognitive and social emotional development into their classrooms. With the implementation of several required standardized tests, school districts have been forced to focus only on academic scores in order to receive good grades on these large-scale assessments. The consequence of these tests is that students have been given less time to work on and cultivate creative activities and ideas in the classroom, including time for free play. Methods such as intentional teaching have emerged to help teachers combine both academics and play or exploration into the same lesson plans. The goal of our research will be to explore both the benefits and drawbacks of prioritizing play in the everyday classroom.

STUDENTS Katherine Victoria Evans, Alexa Dehner Passafiume ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The aims of this research is to see how individualized learning plans can benefit the development of well-rounded students in secondary education programs. Specifically we will be focussing on the use of alternative classrooms and alternative scheduling within high schools and the benefits that come with them.Through the use of flipped classrooms and the inclusion/choice of electives, specifically in the arts, one can receive a more well-rounded education that will help them in both the world and in their further education. Going beyond the traditional ways of earning credit in high school can help the students develop a more personalized education, therefore ensuring more of a balance in the education of the whole person. Giving students more choice and flexibility within their schedule will allow them to focus on their passions and become more advanced in their interests. Additionally the integration of arts within a student’s education through both electives and within other classes can lead to benefits in other academic areas, allowing for students to get the most out of their high school experiences. Both alternative classrooms and alternative scheduling provide a more individualized approach to education which allows for students to gain control of the path that they take through their secondary education experiences. By giving students an ability to choose gives them more of a sense of ownership and responsibility when it comes to their education which oftentimes leads to better outcomes in their education as a whole.

Educating the Whole Person

For one person, they are researching the negative effects of sex education discrepancies on students. For another person, they are researching the benefits of a STEAM education. Finally, another member is researching outdoor education in urban schools and its impact. Together, this combined research is aimed towards the education of the whole person. Both outdoor education and sex education are, in a way, a science. Regarding sex education, adolescents are informed about the importance of consent, physical safety, and emotional safety. Each of these aspects of sex education is founded in scientific research of the effects of adolescent sexual activity on the human body and mind. For outdoor education, a hands on education in science can increase intrinsic motivation both inside of the classroom and out. For STEAM education, students are taught a new approach to learning as a way to solve problems in their community. Ultimately, our combined research informs how to educate the whole person.

Immigrant and Refugee Struggles in Education

Goal 4: Quality Education Goal 16: Peace, Justice, and Strong Institutions STUDENTS Charlotte A Mahoney, Elena Jean Niese ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The student population of the educational system in America is being flooded with a multitude of culturally diverse needs, language being one of these important factors that impact a student’s success. One of the populations that is becoming increasingly affected is that of refugees. Being the recipient of two-thirds of the resettled refugee populations, the United States has found a furthering need to accommodate the inclusivity and academic success of these students in the classroom. This is present in communities across the world, and a common theme in the United States and other countries is the interactions of minority populations with the dominant culture. As bicultural and bilingual students enter education systems, teachers are adjusting their methods in order to accommodate this population of students. This includes respecting the student’s first languages (L1) while integrating their acquisition of the second language (L2). Schools, in addition to a student’s home life and other communities, serve an integral role in encouraging healthy development of students’ languages. By recognizing the importance of students’ backgrounds and cultures, schools can help their students strengthen their identity and what they value.

Goal 10: Reduced Inequalities STUDENTS Elizabeth Downey Hanold, Aine Rosaleen Harless, Christina M Zaso ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Schools around the world struggle to include students with disabilities in the classroom environment. Through the combination of individual research, the information provided shows that the inclusion of students with disabilities in the classroom lets all students make greater strides in their academic successes through the diverse learning levels. This diversity decreases the stereotypes that surround those with disabilities when their neurotypical peers see all their shared characteristics. Inclusion fosters strong relationship formation between students with disabilities and students in general education. Inclusion with peer support arrangements create a classroom that is full of success.The connection peers get to make with the students with disabilities helps the overall well being of students by allowing peers and students with disabilities to both thrive inside the classroom and receive benefits from this learning experience. When educators teach students with disabilities strategies that improve their learning, students are better able to articulate and express their ideas. This allows students with disabilities to more confidently engage in the classroom, but also with the attention and help they need from the teacher because of their disabilities, these students will begin to see and take pride in their academic success. Inclusion of students with intellectual and learning disabilities creates a more diverse learning environment where everyone can succeed.

Literacy is the key to a student’s success as it is a critical skill required for learning all other subjects, including science and engineering (Annie E. Casey Foundation, 2010; Harvey, 2010). The Third Grade Reading guarantee encourages PK-3 teachers to focus solely on mathematics and reading (National Research Council, 2012; Ohio Department of Education [ODE], 2015). Because of this, students in these early grades are rarely exposed to science and engineering. This is very unfortunate since research shows that early exposure to science and engineering increases a student’s likelihood of pursuing these career fields. However, one of the most effective educational strategies is teaching literacy and Science, Technology, Engineering and Mathematics (STEM) in a highly integrative manner (Sterling, 2014; Cervetti, Pearson, Bravo, & Barber, 2006; National Academy of Engineering, 2008; Cervetti, Barber, Dorph, Pearson, & Goldschmidt, 2012; Padilla, Muth, & Padilla, 1991; Guthrie & Ozgungor, 2002; Palincsar, & Magnusson, 2001; Romance & Vitale, 2001; Campaign for Third Grade Level Reading, 2016). To address this issue, the STEM Stories project provided innovative, engaging, fun and highly integrated STEM and Literacy curriculum that was facilitated by undergraduate engineering and teacher education students to second and third grade students at three local schools: Fairview, Kiser and Ruskins.The activity modules were developed using research based best practices for attracting underrepresented students to STEM, to show how STEM can make a difference and impact people’s lives and to incorporate culturally relevant literature and targeted literacy activities (National Academy of Engineering, 2008). The activity modules were facilitated at three schools in the Dayton area. Throughout the experience, we were able to see the impact that facilitating the modules had on the development of the second and third grade students. Participants in the program expanded their writing abilities from less than a sentence to full paragraphs and pages. Participants in the program were also able to learn to engage with the engineering design process while further developing math, science, and writing skills. We were able to gain experience leading a classroom and actively engaging with elementary

Summer Reading: Successful Implementation and Practices College of Arts and Sciences: English Oral Presentation - Capstone Project Goal 4: Quality Education STUDENTS Brooke Nicole Doll ADVISORS Bryan A Bardine LOCATION, TIME Kennedy Union 311, 4:00-4:20 The school district in which I work has implemented a summer reading program at the high school for the past two years but has recently abandoned this practice. While enthusiasm from English teachers and administration for the program was initially clear, the purpose and direction of the program was not. A group of English teachers was originally tasked with discussing and choosing a book that the entire high school would read over the summer. Students would then be held accountable for their reading through classroom activities and assessments during the first two weeks within their English courses. Yet, with the committee established, there was still no communication between the high school, the administration, and the community about what we were trying to accomplish. With this lack of focus and intention, no real rationale or goal for the program was ever established and the program quickly lost support from the administration. Yet, the summer reading program committee is determined to continue the practice that has been adopted by numerous other school districts and has begun the process of reinstating the program for the next school year. My intention is to understand why and how effective summer reading programs are created and executed and to eventually present my findings to both colleagues and administrators. The research I will perform is the foundation of my capstone project as it will give me actionable data I can share with my colleagues which will hopefully further and strengthen the program. Additionally, the scholarship I find on other successful programs will give me direction in terms of how I will create surveys and interviews to help me understand the climate of the community in terms of how they feel the program succeeded and failed in the past.

Impact of a Catholic and Marianist University Experience on Career and Education School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research Goal 4: Quality Education STUDENTS Anna Kathleen Wilhelm ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 A number of students choose to attend religious universities based on their personal beliefs, or faith practices that they hope to further develop while in college. However, the particular values or skills established during college may or may not continue to manifest themselves as individuals advance in their careers or education. The purpose of this study is to explore the impact of a Catholic and Marianist university experience on one’s career and/or further education. More specifically, we aim to learn more about how alumni of Marianist universities in the United States feel that their Catholic and Marianist education has influenced their career journey and/or experience in earning additional degrees. This qualitative study includes interviews with alumni of Catholic and Marianist universities in the United States and seeks to determine the impact of their Catholic and Marianist college education on their careers and further education.

Place-Based Community Engagement and the Development of Self-Authorship in Undergraduate Women of Color School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research Goal 4: Quality Education Goal 5: Gender Equality STUDENTS Ajanti Simone George ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 A central goal of higher education professionals is to promote self-authorship within the students that they serve; that is, helping students develop their internal capacity for discerning who they are in relation to their identity, values and social exchanges. Place-based community engaged learning challenges colleges and universities to assess the degree to which their espoused values of citizenship and activism at the institutional level are aligned with their actions; it is a multi-layered approach that requires institutions to reexamine policies that are rooted in oppression and maximize reciprocity. Understanding the historical context surrounding a university in relationship to community engaged efforts is especially important as institutions pursue racial equity and a more diverse student body. More specifically, understanding the experiences of women in color in higher education is key to uncovering the ways in which their racial identity plays a role in their unique interpretation of community engaged efforts and how they subsequently learn to negotiate their own values and beliefs rather than assimilate to the majority. The purpose of this qualitative phenomenological study is to better understand the impact that participation in place-based community engagement has on the development of self-authorship in self-identified undergraduate women of color at the University of Dayton. Grounded in the constructivist paradigm, this study is intended to further the profession’s knowledge about how practitioners can partner in student learning as they grow in their own awareness of self, with a nuanced understanding of a diverse sub-population.

Oral Presentation - Course Project, 201910 HST 485 01 Goal 5: Gender Equality STUDENTS Sarah Bryanne Litteral, Lauren Catherine Lowen ADVISORS Bobbi Sue Sutherland LOCATION, TIME Kennedy Union 312, 2:40-3:20 This session presents our research in medieval culture, both high culture and the “low” culture of common people, especially as it relates to gender. Our papers will examine the role of powerful queens in Spanish society on the one hand, and the vulnerability of women in rape and prostitution on the other. As with our classmates papers, we find that these aspects of pre-modern society and culture interact and interconnect with many other areas of medieval and early modern life.

This art form has evolved over the years from a collection of beautiful songs that form a story to stories that can’t help but be told through song. With selections by composers from Rodgers and Hammerstein to Lin-Manuel Miranda, Mitchell and Saliba will take audiences on a journey through this evolution and these stories told by women of all backgrounds on stages throughout the years.

Nitrate contaminant tracing in surface and groundwater in the Great Miami River Watershed: Environmental Isotope Approach College of Arts and Sciences: Geology Poster - Honors Thesis

Goal 6: Clean Water and Sanitation STUDENTS Rachel Kristine Buzeta ADVISORS Zelalem K Bedaso LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The global population has increased exponentially causing several challenges surrounding sustainability, including greater food production needs. To meet these demands and boost agricultural productivity, more efficient practices and fertilizers are used. Synthetic fertilizers and other nutrient sources have resulted in water quality degradation and pollution. Much of the Great Miami River Watershed’s streams and aquifers in southwestern Ohio are affected by nitrate contaminants originating from anthropogenic sources including synthetic and organic fertilizer used for agriculture, human wastes (domestic, industrial, and municipal wastes), and urbanization. High nitrate concentrations cause ecological disturbances across all trophic levels. Nitrate levels greater than 10 mg/L also pose a danger to human health, if the contaminant reaches drinking water sources. Water quality monitoring stations report nitrate concentrations in surface and groundwater, but a nitrate contaminant source has not been identified. Here we used isotope ratios of nitrogen (δ15N) and oxygen (δ18O) in nitrates to identify sources for surface and groundwater. Initially we fingerprinted the isotopic composition of the main nitrate contaminant sources in the watershed. Our results show a distinct low δ15N for commercial synthetic fertilizers (0.4±4‰) and high δ15N for animal and human waste (13.0±1.3‰). Further sampling along the Great Miami Mad, and Stillwater River provides insights into contaminant sources contributing to elevated nitrate levels in each river. In general, the δ15N from river samples collected during the low river flow lies within a range of human and animal waste, whereas δ15N values of groundwater suggest that the nitrates might have been derived from soil organic matter or synthetic fertilizers. This research provides a regional baseline for nitrate contaminant source tracing and helps to better inform state and local water quality and nutrient management planning.

Interaction Between Peracetic Acid and Common Stormwater Constituents School of Engineering: Civil, Environmental and Engineering Mechanics Poster - Independent Research

Goal 6: Clean Water and Sanitation STUDENTS Maggie Anderson ADVISORS Denise G Taylor LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Currently, chlorine is the standard chemical used for the disinfection process in storm and wastewater treatment. Due to environmental complications involved in chlorine usage, peracetic acid (PAA) has been proposed as an alternative. Properties such as a faster decay rate and lack of toxic byproducts allows for the chemical removal step to be eliminated, saving time and resources. The goal of this study is to perform baseline testing to quantify loss of PAA under varying conditions. Different types of sands/soils as well as filtration processes could interfere with the efficacy of PAA and must be considered when calculating proper input rates of the chemical for large scale treatment plants. In the end, water mixtures with higher nutrient demands and organic content led to a higher PAA demands, resulting in less PAA availability for disinfection. By standardizing PAA requirements based on the physical and chemical properties of stormwater influent, this alternative to chlorine could be implemented in combined sewer systems.

Surface and Groundwater interaction in the Great Miami Valley Watershed: Isotope Geochemical Approach 69

UN SUSTAINABLE DEVELOPMENT GOALS

College of Arts and Sciences: Geology Poster - Course Project, 201910 GEO 498 05 Goal 6: Clean Water and Sanitation STUDENTS Caroline Johnstone ADVISORS Zelalem K Bedaso LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Groundwater-surface water interaction play a vital role in determining the quality and quantity of groundwater as well as sustainable water resources management. Surface water and groundwater are key components in the water cycle that variably interact depending on geology, topography, and rainfall seasonality. We use environmental isotopes of Hydrogen (δD) and Oxygen (δ18O), which are conservative dual tracers, to provide key information on the movement and flux of water in the hydrologic cycle, degree of mixing between reservoirs, and spatial and seasonal variation of surface and groundwater interaction. Here we examine the degree of surface and groundwater interaction in the Great Miami Valley Watershed (GMVW). Weekly precipitation samples from Dayton, OH, spring and fall groundwater samples from the Great Miami Buried Aquifer and weekly river water samples from four locations (Still Water River, Mad River, and two locations on the Great Miami River) were collected and analyzed for δD and δ18O. Our initial data set shows that the average isotopic composition of the rivers is -6.71±0.19 ‰ for δ18O and -42.63±1.11‰ for δD during the warm season and -7.42±0.12‰ for δ18O and -47.69±0.88‰ for δD during the cool season.The average isotopic composition for groundwater is -7.16±0.49 ‰ for δ18O and -45.29±2.73‰ for δD during the spring and -7.05±0.50‰ for δ18O and -44.72±2.83‰ for δD during the fall. Our result based on an isotope two-component mixing model shows high degree of connectivity between surface and groundwater in the Miami Valley. Locally, rivers and the Great Miami Buried Aquifer shows more than 75% mixing. The outcome of this study will provide useful information on available seasonal groundwater recharge and aid in future water resource management.

Geospatial Wetland Vulnerability Assessment in Greene County, Ohio College of Arts and Sciences: Geology Poster - Capstone Project

Goal 6: Clean Water and Sanitation Goal 11: Sustainable Cities and Communities STUDENTS Tessa Louise Farthing ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Wetlands are an important component of the natural environment. They improve water quality, provide an ecosystem for a great amount of biodiversity, and act as a form of natural flood mitigation. Groundwater eutrophication from various sources of pollution can cause changes in microbial, marine, and plant ecology and therefore require the necessary management practices of the areas. In this study, we analyzed a range of environmental factors to determine the vulnerability to contamination for the Greene County, Ohio wetlands. An index of susceptibility was calculated based on specific parameters of the EPA DRASTIC groundwater assessment method. The specific factors utilized in this study were depth to water, net recharge aquifer media, and topography. In addition, we incorporated land use and other potential sources of pollution to create a more inclusive set of parameters. A geostatistical analysis was conducted to determine the amount and location of wetland areas in Greene County that are subject to a high index of susceptibility. Defining the susceptibility of wetlands helps in decision making for sustainable urban planning as well as determining the wetland areas that are at the highest risk for pollution and may require the most time and funding for research and management practices.

Goal 7: Affordable and Clean Energy STUDENTS Ashish Gogia ADVISORS Vikram Krishna Kuppa LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Polymeric systems are modified routinely by addition of inorganic nanoparticles for enhanced properties and functionality. Such nanocomposites may contain fillers of varying miscibility, such as carbon black, silica, metal oxide, pigments, and /or various combinations thereof. However, on main impediment in the development of high-performance polymer nanocomposites (PNCs) are to realize a good dispersion of nanoparticles, owing to the strong interparticle interactions and weak polymer-nanoparticle interfacial interactions. Hence, the state of dispersion of the polymers and fillers is crucial to the behavior of polymer nanocomposites. To address this issue, in this research, we perform Dissipative Particle Dynamics (DPD) simulation of these blends, varying polymer-polymer, filler-filler and polymer-filler interaction

In addition, the simulation results are also validated experimentally through small angle x-ray scattering data to provide insight and understanding of how these complex structures develops in these multicomponent systems.

Alternative Routes for Ethanol Extraction Using Green Solvents and Nanotechnology School of Engineering: Chemical Engineering Poster - Course Project, 201910 CME 499 03 Goal 7: Affordable and Clean Energy STUDENTS Joseph Daniel Knurek ADVISORS Erick Vasquez LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Ethanol has emerged as a promising alternative biofuel source in recent years. However, current separation techniques for ethanol processing require high energy consumption, causing large scale production to be inefficient. One area of potential improvement in separation cost could be in nanoparticle-enhanced liquid-liquid extraction; removing ethanol from an aqueous solution utilizing castor oil as a green solvent. A castor oil-ethanol mixture would allow for easier separation and purification of ethanol, due to the large difference in the species’ boiling points. It is hypothesized that adding lignin-coated iron oxide nanoparticles to the aqueous solution would increase the transfer efficiency of the solute. Additionally, these nanoparticles would render the mixture superparamagnetic properties, allowing for a magnetic field to be induced around the fluid in separation, further increasing the transfer efficiency due to the magnetic motion in the liquid. This work focuses on setting up prototype equipment that includes a mixer with a magnetic field generator for liquid-liquid extraction magnetic separations. The ultimate goal of this research is to determine if an increase in ethanol transfer efficiency can be seen from the addition of the lignin coated magnetic nanoparticles to the aqueous and green solvents mixture, and if a further increase in transfer efficiency can be seen from the introduction of a magnetic field to the fluids during separation.

Curran Place and the panels on top of Fitz Hall do not provide nearly as much power as we expected. This was researched to see if there were any alternatives to help increase the impact that the existing solar panels have as well as look at other places solar panels can be installed around campus. We will consider the use of other alternative energies, efficiency improvements, and the different types of solar systems used on campus.

Real World Comparison of Modern Power v. Alternative “Green” Energy School of Engineering: Chemical Engineering Poster - Course Project, 201910 EGR 374 01

UN SUSTAINABLE DEVELOPMENT GOALS

ADVISORS Jeremy M Erb LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Recently, there has been a growing interest in the boron dipyrromethene (BODIPY, 4,4′-difluoro-4-bora-3a,4a-diaza-s-indacene) compounds. BODIPY compounds have fascinatingproperties that allow for the absorption and emission of light in the near-infrared region of theelectromagnetic spectrum. These molecules are highly modifiable making them ideal chemicalsfor the use of photoelectric energy conversion such as for commercial use in dye-sensitizedsolar cells (DSSCs). It has been previously shown that different meso compounds have only aslight effect on the absorptive capabilities of these BODIPY compounds. We believe that theBODIPY compounds’ lack of planarity is one of the major obstacles in more efficient absorptionin the NIR and IR regions. Because of this, we are focusing on modifying recently synthesizedBODIPY compounds in an attempt to align their meso group with the rest of the compound’sframework. Synthesis of various BODIPY compounds was attempted in order to perform thering fusion reaction between the meso group and the body of the compound. Computationalanalysis on several BODIPY compounds was performed on these in addition to othercompounds from the literature.

Photometric and Chemical Kinetic Studies of Singlet Oxygen Quenching by Native and Acid-Blue β-Carotene: Implications for the 515nm Effect in Photosynthesis College of Arts and Sciences: Chemistry Poster - Independent Research

Goal 7: Affordable and Clean Energy STUDENTS Claire Elise Hendrickson, Ashlee Wertz ADVISORS Mark B Masthay LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 β–carotene (βC) is an orange pigment present in green plants, where it plays a protective role against the harmful effects of light. It does this by deactivating “singlet oxygen”— a toxic oxidizing species generated during photosynthesis. During photosynthesis, βC temporarily converts from its “native orange βC” state to a “pink βC” state. We hypothesized that pink βC will quench singlet oxygen less efficiently than native orange βC. To test this hypothesis, we chemically modeled pink βC with “blue βC–TCA complexes”, created by reacting βC with trichloroacetic acid (TCA). The singlet oxygen quenching efficiency of native βC and βC–TCA complexes was characterized in two ways. First, in the summer of 2017, we measured the rate of degradation of the singlet oxygen substrate DPBF in the presence of native βC and βC–TCA complexes. Second, in the summer of 2018, we used a near–infrared photometric detector to measure the intensity I1270 near–infrared 1,270 nm light emitted by singlet oxygen in the presence of native orange βC and blue βC–TCA complexes. Surprisingly, our DPBF–based and I1270–based results all indicate that native orange βC and blue βC–TCA complexes quench singlet oxygen with roughly equal efficiency. In the summer of 2019, I will use the Chemistry Department’s computational Gaussian software to characterize the sensitivity of the triplet state of βC (3βC) to the presence of electrically polarized environments such as those present in βC–TCA complexes and in pink βC. Because 3βC likely plays a crucial role in the deactivation of singlet oxygen, and because βC–TCA complexes are structurally similar to pink βC, these studies will provide new insights into the role of pink βC in photosynthesis.

Control of Unbalanced Power Sharing in Islanded AC Microgrid with Balanced and Unbalanced Loads School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 7: Affordable and Clean Energy Goal 11: Sustainable Cities and Communities STUDENTS Ahmed S Alsafran ADVISORS Malcolm W Daniels LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Managing power sharing between islanded microgrids adds additional capability to existing Smart Grid configurations enabling otherwise isolated microgrids to share power. In geographies where population centers are widely dispersed and particularly, in countries that lack a robust and effective grid, these technologies enable growth in consumption and improved supply security when isolated microgrids are interconnected with feeder lines to shared loads. The challenge is to effectively control this power sharing capability in an environment where microgrid performance is substantially load dependent and where the interconnection capabilities between microgrids often grows organically to meet demand. The proposed control has advantages over other methods since it does not require communication capabilities between the interconnected microgrids and does not require knowledge of feeder line models.This paper addresses a proposed control system design for these systems that has a hierarchical structure to manage power sharing among distributed generation (DG), low voltage AC islanded microgrids with unbalanced loads. The proposed control consists of three parts. First, an active power (P) – frequency (f) droop control and a reactive power (Q) – voltage (V) droop control (P/f and Q/V) are used to enable the active and reactive power sharing between two interconnected DGs. Since this droop control is unable to share unbalanced power effectively, a negative phase sequence virtual impedance control is added as a second control to regulate the distribution of unbalanced power. Third, an unbalanced power and small signal

UN SUSTAINABLE DEVELOPMENT GOALS

frequency droop control is added to adjust the impedance value (L v) in the negative phase sequence virtual impedance control to force the negative sequence current to reach the steady state operating point achieving unbalanced power sharing.The proposed control scheme is theoretically designed the effectiveness of this proposed control scheme is evaluated through simulation studies. The impact of both the feeder line model and the unbalanced load on power sharing effectiveness are investigated.

Design and Characterization of a Wind Lens Grid Array School of Engineering: Mechanical and Aerospace Engineering Poster - Graduate Research

Goal 7: Affordable and Clean Energy STUDENTS Neal Novotny ADVISORS Sid Gunasekaran LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 A novel solution to circumventing the requirement of large scale wind turbines for increased power output is the Wind Lens Turbine (WLT). WLTs have been shown to improve power output by a factor of 2-5 when compared to traditional style wind turbines. This work presents the use of several small-scale WLTs (1 ft. in diameter) in a grid configuration as a solution to large scale wind turbines and outlines the methodology and power output from a grid. Further, this work presents an analysis of the Reynolds number effects on small-scale WLTs. All experimental investigations were conducted in the University of Dayton Low Speed Wind Tunnel (UD-LSWT). Initially, the individual rotor performance is optimized for low Reynolds numbers. A sensitivity on the number of blades was conducted through a numerical analysis tool called Q-blade. Initial results displayed that an increase in the number of blades (8-14) is more effective for small scale wind turbine power output. Effective airfoils for low Reynolds number applications were found to be thin, highly cambered airfoils. The results of this numerical study was validated using wind tunnel testing. The aerodynamic interaction of the lenses in a 1-D and 2-D grid will be quantified. This will be performed as a force-based testing of flat, circular disks (analogous to WLTs) in close-proximity. The final step is to perform field testing to validate and model the interaction of multiple WLTs in 1-D, 2-D and 3-D grid.

The Importance of Novel Molecule Properties in the Formation and Advancement of Alternative Jet Fuel Blends School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

Goal 7: Affordable and Clean Energy STUDENTS Lily Carolyn Behnke ADVISORS Joshua S Heyne LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The development and use of new alternative jet fuel blends and high energy molecules has the potential to greatly improve conventional jet fuels, both environmentally and economically. These fuels and blends are dependent upon their performance and operability standards as well as the chemical and physical properties of the novel molecules within them. High energy molecules have the potential to increase the total specific energy (MJ/kg) and energy density (MJ/L) values of a fuel with the intention of increasing overall aircraft efficiency. The properties of these high energy molecules are essential in determining their viability for blending and optimization, and therefore must be thoroughly analyzed to consider the eligibility of these molecules. The blending of novel high energy molecules with conventional jet fuels are bounded by ASTM specifications to produce alternative jet fuel blends that could be implemented in commercial airlines. With a global optimum in mind, the progression of alternative jet blends has the potential to improve aviation by lowering gas emissions and improving overall aircraft performance.

Implementing Energy Saving Behaviors in Low-Income Communities School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

Goal 7: Affordable and Clean Energy STUDENTS Jenn Margaret Hoody ADVISORS Anya M Galli Robertson, Kevin P Hallinan LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The necessity to combat climate change is on the rise as more and more studies are revealing the catastrophic outcomes if the current trends of energy consumption do not change. Residential programs to promote energy savings and reduce consumption are being enacted to decrease the greenhouse emissions due to home energy usage. However, thus far, little to no measures have been taken to extend the reach of such programs to low-income communities. Reducing household energy consumption would be extremely beneficial as it would lower utility bills for low-income households who spend a substantially greater portion of their income on energy bills compared to other

UN SUSTAINABLE DEVELOPMENT GOALS

households. While installation of energy efficient appliances is a dominant component in energy reduction, adopting energy behavior has the potential for significant savings. Research is being conducted to determine the most effective techniques necessary to successfully promote and enact energy reduction behaviors in low-income communities based upon peer-to-peer methods. Through a program that will track and analyze thermostat and consumption (energy and water) data in a low-income neighborhood in Dayton, behavioral models will be designed and implemented to deduce what education and intervention methods produce optimal energy behavior results, how demographics impact energy behaviors, and what factors most strongly correlate to an increase or decrease in energy consumption.

Advanced Data Analytics and Optimal Control of Building Energy Systems School of Engineering: Mechanical and Aerospace Engineering Poster - Graduate Research

Goal 7: Affordable and Clean Energy Goal 9: Industry, Innovation, and Infrastructure STUDENTS Abinesh Selvacanabady ADVISORS J Kelly Kissock LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 This research addresses key issues for applying advanced building data analytics to energy efficient control opportunities. First the research identifies advancements and potential hurdles around the three primary means for acquiring data: energy management systems, dedicated measurement systems, and advanced computer software that accesses and archives data from energy management systems. These are described using case studies from commercial building control systems and web-based real time dedicated measurement technology. Next, the research describes effective rule-based data analytics and control strategies that are traditionally used. Rule-based data analytics utilize specific knowledge about HVAC systems to identify key data points and analytical methods to identify energy saving opportunities and develop improved control algorithms. The research describes both theory and application of these rule-based analytics for the control of systems like air-side economizer, ventilation fans, pumping and chilled water systems. Finally, the research proposes a framework to apply advanced machine learning and data mining techniques to the same problem. Machine-learning control differs from rule-based control in that this control type requires less specific knowledge about HVAC systems. The proposed framework uses existing data, where available, to pattern match and build robust models emulating the performance of the system under consideration. To these models, classical optimization algorithms (knapsack, greedy and shortest distance) and mathematical framework (Game theory and Design of Experiments) are adapted and applied to reach the best control strategy. For systems without past performance data, a stochastic framework using decision chains (Markov processes) and adaptive controls using the reinforcement learning method is proposed for the same. These techniques are demonstrated on select systems e.g. Pumping plants and HVAC systems.

Effects of Non-Interactive Virtual Reality Advertisements on Brand Recall: A Pilot Study College of Arts and Sciences: Communication Oral Presentation - Graduate Research

Goal 8: Decent Work and Economic Growth STUDENTS Ashton Lee Kiplinger ADVISORS Benjamin R Kunz, James D Robinson LOCATION, TIME Kennedy Union 312, 9:40-10:00 As Virtual Reality Head Mounted Displays (HMDs) have gotten cheaper and proliferated into the consumer product space, marketers have begun releasing branded content for these systems. While researchers have found that consumer attitudes towards brands are more positive when video advertisements are displayed in three dimensions, there is no data on whether this translates into higher brand recall. This pilot study seeks to test whether non-interactive virtual reality advertisements help or hinder brand recall. By showing subjects branded content using an Oculus Rift HMD and subsequently testing their recall of which brands they were exposed to, it is possible to test whether or not this research is worth pursuing on a larger scale. This research has potentially groundbreaking implications for the future of advertising and virtual reality.

The Grand Ethiopian Renaissance Dam: A Window of Opportunity or a Door for Exclusion? College of Arts and Sciences: Geology Poster - Independent Research

Goal 8: Decent Work and Economic Growth STUDENTS Alyssa Marie Miller ADVISORS Zelalem K Bedaso LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The Nile River is one of the longest rivers in the world that flows through 11 countries. The Blue Nile River is a tributary to the Nile River, which starts from the highland of Ethiopia and contributes around 85% of water flow to the Nile that flows upstream into the Mediterranean Sea. With the aims to solve the water problem and enhance their development, the Ethiopian government started building the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River in 2011. Since this river is a tributary to the Nile River, many spectators questioned how Ethiopia has the jurisdiction to build a dam over a river that is transnational. There have been various legislation agreements established, but very few have had significant impact to lessen the tension. Most notably, to solidify each country’s adequate supply, the UN adopted the Convention on the Law of the Non-navigational Uses of International Watercourses in 1997, which attempted to set standards around the usage and conservation of watercourses. Though this convention can help resolve the geopolitical tension over the GERD’s construction on the Nile River, it does not solve the question of Ethiopia’s right to build a dam that could impact other countries water supply. Therefore, in 1999, the Cooperative Framework Agreement (CFA) grants each country that the Nile River flows through, the right to adequately use the Nile’s water supply. However, Egypt is one of the countries that originally did not sign the CFA. The Nile is Egypt’s primary source for freshwater. Egypt’s main concern is since their population continues to grow, their freshwater supply will deplete. Though it may be perceived to negatively impact Egypt, the GERD seems to benefit countries, especially Ethiopia and Sudan, in terms of economic development. Hence, I am to explore how the GERD will benefit and restrict Ethiopia, Sudan, and Egypt’s commercial growth. I will also explore journal articles and media sources to further analyze the complex geopolitical situation in northeastern Africa.

Characterization of Fabricated Photodetectors School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

UN SUSTAINABLE DEVELOPMENT GOALS

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Roseanna George Lawandi ADVISORS Andrew M Sarangan LOCATION, TIME Science Center 62, 1:00-1:15 Silicon photodetectors are semiconductor devices that convert light into electrical signal. They are utilized in many different applications such as photography, spectroscopy, medical imaging instruments, and optical communications. Since these devices are very small, fabricating them in the lab is necessary before any adjustments can be made. In order to fabricate photodetectors, many processes were performed followed by testings to characterize them. One way of characterizing a photodetector is by measuring its spectral responsivity (also known as radiant sensitivity). This quantity describes the performance of the photodetector as a ratio of photocurrent to incident optical power. Therefore, the spectral responsivity of the fabricated photodetectors was measured using an integrating sphere and the results were compared with a commercially available photodetector.

A Study of Privacy Leakage and Protection on the Web College of Arts and Sciences: Computer Science Oral Presentation - Independent Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Zhengying Zhou ADVISORS Phu Huu Phung LOCATION, TIME Kennedy Union 311, 1:00-1:20 On the Internet, the activities of users are often tracked by the “third-party” companies so that they can share users’ information among websites for commercial purposes. However, these sharing mechanisms raise security and privacy issues for users since personal information may be leaked on cyberspace without knowledge of the users. In this work, I study the state-of-the-art techniques in web-tracking technology to evaluate the security and privacy issues on the Web. I then propose an approach that loads the web-tracking code into a sandbox environment so that its behaviors can be enforced by desired policies. This mechanism provides the end-user capabilities to control what to be shared so that it can still leverage the advantages of the technique to enhance the user experience on the Web. I will demonstrate the experiments of how third-party tracking works and the possible way to secure users’ privacy based on my approach.

Thermal profile engineering with multi-beam laser additive manufacturing School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS George Lewandowski ADVISORS Mikhail A Vorontsov LOCATION, TIME Science Center 62, 1:15-1:30 Laser additive manufacturing is used to create metallic structures with complex geometries. The ability to control material properties of the fabricated parts can be exploited to tailor the mechanical performance for a specific application. In particular, the rate of solidification can be controlled to influence the resulting microstructural grain morphology between columnar and equiaxed regimes. Recently, a new laser energy source that consists of an array of beams with individual control of both position and power has been implemented for use in a powder bed selective laser melting system. In this work we perform numerical simulations of the laser additive manufacturing process using a reduced complexity analytical heat transfer solution in order to identify specific multi-beam configurations that result in different solidification scenarios. A stochastic gradient descent optimization procedure is executed utilizing a novel metric designed to control the thermal history to achieve reduced thermal gradients during the solidification process, thus leading to a higher percentage of equiaxed grains.

Characterization of Novel Phosphorus-Based Flame Retardants in Epoxy Resins School of Engineering: Chemical Engineering Poster - Graduate Research

UN SUSTAINABLE DEVELOPMENT GOALS

UD Chemistry Department faculty. The FR includes both primary and/or secondary amine functional groups which allow it to potentially react with the epoxy resin through covalent bonding. Previous work involved examination of several similar flame retardants which showed good results in terms of curing behavior and flammability properties. Despite these results, scale-up of the formulations from small scale (~ 1 gram) to a larger scale (10s of grams) led to unexpected results, for example, the generation of gas bubbles during cure which was not observed in the initial small scale studies. In response, a series of experimental mixing formulations and curing conditions were investigated to provide further insight. Curing conditions were characterized by various physical and thermal properties using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). In the current study, we will try to overcome some of these problems that were experienced in the previous study in order to make controlled samples for further flammability testing.

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Katherine Morris Burzynski ADVISORS Christopher Muratore LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Consumers and military personnel alike are demanding ubiquitous electronic devices which require enhanced flexibility and conformality of electronic materials and packaging, while maintaining device performance. Whether it be high-power devices for faster data speeds, such as fifth generation wireless communication technology or wearable sensors to facilitate the Internet of Things, the age of flexible, high performance electronic devices has begun. Managing the heat from flexible electronics is a fundamental challenge. Even on rigid substrates with significantly higher thermal conductivity than polymeric substrates, the full potential of semiconducting materials is often thermally limited. The flexible gallium nitride (GaN) transistors employed in this work are conventionally processed devices that can be released from their growth substrate and transferred to a variety of rigid and flexible substrates. Characterization of the GaN device behavior on the as-grown sapphire wafers provide a baseline for evaluation of engineered substrates. Thermal imaging of devices in operation reveals that the current passing through an as-grown GaN transistor reaches the target operating temperature at approximately five times the power of the same device transferred to a flexible substrate. Printable, thermally conductive nanocomposites integrating 1D, 2D, and 3D forms of carbon in a flexible polymer matrix, as well as metal nanoparticles, were developed to maximize heat transfer from electronic devices. The thermal conductivity of the candidate substrate materials was measured experimentally to have more than a 900 percent increase in thermal conductivity (from 0.2 to 1.7 W/mK), while maintaining desirable mechanical properties. The performance of devices transferred to these novel flexible composite substrates was characterized and used in computational simulations to predict flexible substrate architectures that effectively promote point-to-volume heat transfer to further improve device performance. Additive manufacturing for engineered architectures of the flexible, thermally conductive substrate materials was demonstrated to substantially reduce the thermal limitation of high-power flexible electronics.

Analysis of Safety Impact of Raising Trucks Speed Limit on Rural Freeways in Ohio School of Engineering: Civil, Environmental and Engineering Mechanics Poster - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure Goal 11: Sustainable Cities and Communities STUDENTS Nayabtigungu Hendrix Ouedraogo ADVISORS Deogratias Eustace, Maher B Qumsiyeh LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Large trucks play a key role in the overall safety of the highway transportation system. Previous studies have shown that in Ohio large trucks are over-represented in crashes that lead into serious and fatal injuries [1,2]. Critical factors in truck-related crashes can be divided into environmental, road geometric related, human and driver-related, or vehicle related factors. A previous study that analyzed factors affecting truck-related crashes in Ohio found that posted speed limit and speed-related factors were among the significant factors impacting crash severity of truck-related crashes [1]. Several studies have shown that increasing speed limits on roadways has a significant impact both on safety and operating speeds [3-5]. On July 1, 2013 the Ohioâ&#x20AC;&#x2122;s legislature raised the speed limits on rural freeways from 65 mi/h to 70 mi/h for passenger vehicles, buses and trucks and to date the safety impact of this speed limit raise has not been evaluated. The current study is investigating the impact of raising the speed limit on crash severity specifically with interest with large trucks and buses on rural freeways in Ohio.Statewide crash data have been obtained from the Ohio Department of Public Safety (ODPS) between January 1, 2010 and December 31, 2017. Given the numerous number of rural freeway segments located all over the state and traffic volumes for each segment over the study period are not easily obtainable, therefore the use of standard observational before/after study empirical Bayes (EB) method is not feasible in this case. This research will utilize the time series analysis model, which is a statistical method that can take care the differences in crashes occurring in different years and recognize trends in different periods of times. In essence, time series analysis is a statistical technique that deals with time series data, or trend analysis. Time series data means that data is in a series of particular time periods or intervals.

The security robustness of Modbus/TCP protocol in industrial control systems School of Engineering: Engineering Management, Systems, and Technology Poster - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Hassan Ali Alsaad ADVISORS Mohammadjafar Esmaeili LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Since most of Industrial Control Systems (ICS) systems have been isolated from public networks, there have not been a colossal needs to secure them. However, in most of todayâ&#x20AC;&#x2122;s applications such as Experimental Physics and Industrial Control Systems (EPICS), Supervisory Control and Data Acquisition (SCADA), Distributed Control System (DCS) and Programmable Logic Controllers (PLCs) system are getting connected to the internet without paying attention to the security robustness of these devices. Industrial Control Systems (ICS) such as SCADA, DCS, PLCs are communicating with industrial equipment such as actuators, sensors, motors, and pumps using a special communication protocol called Modbus. For remote applications, multiple PLCs can be connected to each other to form a controlling network that uses Modbus / TCP communication protocol utilizing private/public networks. This research focuses on examining the security vulnerability of the Modbus/TCP protocol. To achieve this goal the researcher utilizes Modbus PLC simulator to simulate different cyber attacks through the local network. The cyber attacks have been formed using the MBTGET Perl script and Metasploit module, in Kali Linux penetration testing operating system. Our research shows some of the major security vulnerability in the Modbus/TCP protocol, which is one of the main communication protocols ICS system.

Regression Analysis of United States Airfare College of Arts and Sciences: Mathematics Poster - Capstone Project

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Sarah Marie Hartness ADVISORS Ying-Ju Chen LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Millions of flights depart in the United States every year. Using a 10% sample of all flights tracked by the Bureau of Transportation Statistics, we will study how much it costs on average to fly domestically and its distribution. We will also take the four most popular states to fly out of (California, Florida, Texas, and New York) and compare the costs people are paying to fly from these states and whether or not people are flying round trip from these states. Regression analysis will be used to study the relationship between several variables (for example, the number of passengers and the distance) and the cost of the flights. Finally, we will look at when people are flying most often. It is expected to be in the last quarter of the year due to the holiday season.

Most leading-edge tubercles studies (inspired from the humpback whale) involve serrated-type leading edges where the airfoil cross-section is destroyed. In this research, the effect of the tubercles is investigated where the airfoil cross-section is preserved along the span of the wing. By maintaining the same airfoil section throughout, reducing the chord reduces the thickness of the wing, creating uneven wing surface contours. These contours are hypothesized to affect the spanwise flow thereby affecting the induced drag, roll-up of the wingtip vortex, and the parasite drag of the wing. Sensitivity study was done on the number of contours along the span (6, 9 and 12) and contour location (leading edge, trailing edge, both leading and trailing edge) by performing force-based experiments at the University of Dayton Low Speed Wind Tunnel (UD-LSWT). The aerodynamic coefficients were compared among the wing with and without contours. The aerodynamic lift and drag coefficients along with variations in aerodynamic efficiency will be presented for wings with and without contours.

Energy Analysis and Orbit Simulation of Actuated CubeSat Solar Arrays School of Engineering: Mechanical and Aerospace Engineering Poster - Honors Thesis

Goal 9: Industry, Innovation, and Infrastructure Goal 7: Affordable and Clean Energy STUDENTS Justin Todd Ehren ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 CubeSats are used in space research to explore new technologies and detect data to gain a better understanding of various subjects affecting human life. CubeSats rely on a solar array to generate energy from the sun and perform their various functions in space. This research studies the energy capturing potential of various solar panel configurations and positioning devices for CubeSats. The location and orientation of a CubeSat is simulated in geo-synchronous and sun-synchronous orbits. Two degree-of-freedom (dof) positioning devices are sufficient to continuously adjust the photovoltaic array to face towards the sun. Lower dof systems are desired as they are less complex. Solar panel configurations included in the study are those affixed to the CubeSat sides, deployed into alternative stationary positions, and actuated with one dof, and with two-dof actuation with mechanical limitations. The energy captured over an annual cycle is determined for each case. For systems with fewer than two dof, optimal position settings are determined for the design parameters.

WebGuard - A Self-Protection Browser Extension College of Arts and Sciences: Computer Science Oral Presentation - Independent Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Panchakshari Nijagunashivayogi Hiremath, Rakesh Sunkaralakunta Venkatarama Reddy ADVISORS Phu Huu Phung LOCATION, TIME Kennedy Union 311, 1:20-1:40 JavaScript is a scripting language used for almost every websites.

Laser Assisted 3D Printing of Nanostructures

School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Md Shah Alam ADVISORS Chenglong Zhao LOCATION, TIME Science Center 62, 1:30-1:45 In this project, a rapid and cost-effective technique of 3D printing or additive manufacturing of nanostructures is presented. Rapid prototyping of 3D printing of microstructures is already well developed and widely used in different areas such as automotive, aerospace, military, dental and medical industries and so on. However, huge development is still needed to improve the prototyping speed and control in the manufacturing process of 3D structures at nanoscale. Here, we have demonstrated a laser assisted transfer process of metallic nanoparticles for 3D nanomanufacturing. In this technique, a droplet of colloidal solution of metallic nanoparticles is dried on a flexible substrate. These nanoparticles are attached to the surface due to van der Walls attraction force. The individual nanoparticles are sequentially exposed to a focused laser beam. The exposed nanoparticle absorbs laser light and causes sudden thermal expansion of flexible substrate beneath the nanoparticle. As a result, a thermal expansion force is applied to the nanoparticle and the particle is transferred to the receiver substrate. Nanoparticles are sequentially transferred to the desired position of the receiver substrate to form designed 3D patterns. Several nanostructures are developed using this rapid release-and-place process which offers enormous prospective of this technique in the emerging 3D nanoprinting technology.

Adaptive Security Policy Enforcement Framework for Hybrid Mobile Applications College of Arts and Sciences: Computer Science Oral Presentation - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Rakesh Sunkaralakunta Venkatarama Reddy ADVISORS Phu Huu Phung LOCATION, TIME Kennedy Union 311, 1:40-2:00 The exponential growth in hybrid mobile applications has exposed itself into a wide spectrum of security risks. With the existing permissionbased security model provided by leading providers like iOS and Android, although mobile applications ask for permissions to access the resources, users can only grant or reject them. Our research work aims at addressing these limitations by enabling the user to customize the access permissions in the applications at run-time.By leveraging our adaptive security policy enforcement framework, the hybrid mobile application developer can inject a stream of security policies with basic configurations into the application. Once the application is installed on the mobile device, the user can explore the friendly graphical interface provided by the framework to customize the security policies to match the usage requirement. The extensive classification of fine-grained policies in the framework provides more flexibility in controlling the resource access permissions as per the need. This dynamic security framework is easy to use for mobile application users yet powerful enough to thwart any malicious attacks which compromise usersâ&#x20AC;&#x2122; privacy or misuse of mobile device resources. We will illustrate the effectiveness of our framework by demonstrating the user-friendly interface for on-the-fly policy customization.

The goal moving forward is to develop strategies to foster positive change on our campus and in our communities, and to design sustainable actions to dismantle injustice in the UD community and beyond.

The Perception of Student Bias from Engineering Faculty in Higher Education School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Graduate Research Goal 10: Reduced Inequalities Goal 4: Quality Education STUDENTS Kyra Elizabeth Twohy ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union 310, 11:20-11:40 This study investigated the engineering faculty perceptions of student bias in a variety of classroom settings, specifically from the point of view of both male and female students. The goal was to show perceived differences between how male and female students rate professors. This is especially relevant as teaching evaluations are a crucial part of tenure and promotion cases. The study used a survey comprised of 25 questions that assessed the level of positive and negative bias for male and female students when evaluating teaching. Forty-eight faculty members from the engineering department of a midwestern university completed the survey. There was also an interview that asked 8 questions about the faculty’s experience with bias and gender bias. Of the forty-eight faculty members who completed the survey, 10 were interviewed. Data from the survey was analyzed using one-way ANOVA tests, as well as descriptive statistics. Qualitative data was obtained from the coded interviews. Results showed that the faculty’s perceptions positioned male students as more positively biased when evaluating male faculty and were more negatively biased towards female faculty, than their female counterparts. Class size also was found to contribute to bias, as class size increases led to increasing perceived negative bias. This study finds that more research should be done to establish a method of removing bias from teaching evaluations, so that course evaluations only reflect teaching ability.

The Prevalence of Aversive Racism in the Reality TV Show Survivor College of Arts and Sciences: Psychology Poster - Independent Research Goal 10: Reduced Inequalities STUDENTS Jessica Nicole Eischen, Michael Terrence Stark ADVISORS Erin Marie O’Mara LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Aversive racism is a form of prejudice and discrimination in which individuals who profess egalitarian ideology and hold non-prejudiced self-views discriminate towards racial minorities in subtle, rationalizable ways (Gaertner & Dovidio, 2000). Unlike overt, intentional racism, aversive racism is characterized by feelings of uneasiness about racial minorities rather than hate and hostility; however, it still results in discrimination towards racial minorities. Research examining white people’s attitudes and behavior towards black people finds that one

UN SUSTAINABLE DEVELOPMENT GOALS

context in which aversive racism occurs is when discrimination towards black people can be blamed on non-racial factors. That is, people fail to identify race playing a role in why they behaved more positively towards other white people than they did black people. The present study seeks to examine the prevalence of aversive racism in the reality-television series, Survivor, where contestants vote someone out of the game each week in order to win a one-million dollar prize. With few exceptions, the majority of contestants each season are white, and attribute their decision of who to vote out of the game to various non-racial factors. We will examine the association between contestant race and the rate at which they are voted off the show by the other contestants. Aversive racism predicts that, although there are usually far fewer nonwhite contestants each season, non-white contestants would be voted-off at a disproportionately higher rate than the white contestants.

Biases in the Classroom

School of Education and Health Sciences: Teacher Education Poster - Course Project, 201910 EDT 110 H1 Goal 10: Reduced Inequalities STUDENTS Matthew J Frabutt, Lanny Glenn Sparks, Anna Catherine Wolfe ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Students are subject to the consequences of a variety of biases present in the classroom based on their genders, personality styles, or academic abilities reflected in their grades. The first inequality present in the classroom can be observed through the different ways teachers treat male and female students. The types of attention teachers give to students, as well as their beliefs in students’ academic capabilities, differ depending on whether the student is male or female. Whether they be conscious or unconscious, these biases have a profound effect on widening the academic achievement gap between girls and boys. Teachers may also be biased in the ways in which they interact with extroverted and introverted students. Teachers and the educational system celebrate and cater to the needs of extroverted students rather than to introverts. The quieter students in the classroom may be perceived as “disengaged” or as students who hold negative attitudes about learning. Yet, although their personalities may not outright display it, the introverted students can prove to have the brightest minds or sharpest attention spans, and teachers must not fail to engage these students and give them adequate acknowledgement. Lastly, teachers may show a bias toward students who possess a higher academic aptitude rather than at-risk or lower performing students. This bias allows for the “smart” kids to excel further and the “dumb” kids to fall further behind. This shows a bias in the classroom because a student’s true capabilities may not be able to be properly expressed in the current grading system.

A Tale of Two Spies: Racial Misidentification and Hyphenated Identities in Danzy Senna’s Caucasia and Chang-Rae Lee’s Native Speaker College of Arts and Sciences: English Oral Presentation - Honors Thesis Goal 10: Reduced Inequalities STUDENTS Will Edward Landers ADVISORS Thomas L Morgan LOCATION, TIME Kennedy Union 310, 3:00-3:20 I deploy critical race theory in a literary examination of passing and racial normality in Danzy Senna’s Caucasia. I focus on Senna’s character of Birdie, an African-American, biracial girl whose appearance is racially ambiguous. I then draw comparisons between Birdie and the character of Henry Park, a Korean-American ethnic spy in Chang-Rae Lee’s Native Speaker. Birdie’s experiences demonstrate incongruencies between visual racial expectations in the United States. Henry’s experiences show the expectations of cultural newcomers to the U.S., as well as the ways that racism is learned by Korean immigrants. Both Senna and Lee use the figure of the spy. Birdie speaks of feeling like a spy and uses her appearance as a disguise, while Henry is employed as a professional spy due to his Korean-American background. The cultures of these characters are different, but their stories as spies reveal key similarities in their American experiences. Historical tensions of race and class divide Korean-Americans and African-Americans, relative newcomers and old residents. However, in the presence of white normality, each group faces some similar challenges to surviving and finding a place in white American society. Racial identities are shaped by the white gaze and, in turn, the perceptions of others groups are formed against a white background.

The Laggard Leader: A Historiography of the Origins of Wage and Income Inequality in the United States, 1973–84 College of Arts and Sciences: History Oral Presentation - Honors Thesis

UN SUSTAINABLE DEVELOPMENT GOALS

ADVISORS William V Trollinger LOCATION, TIME Kennedy Union 331, 3:00-3:20 Since 1973, income inequality has increased dramatically in the United States. Workers who entered the labor market in the 1970s, 1980s, and 1990s did not inherit the same economic security as their predecessors during the “Golden Age” of Capitalism. Their jobs paid relatively lower wages, unionization rates were half the rate they were in the 1950s, and fewer jobs offered the benefits associated with the traditional middle-class lifestyle. After 1973, increases in income growth have been heavily concentrated at the top of the income distribution while wages and incomes for workers at the bottom have stagnated for decades. What economic factors during the 1970s created a distinct shift towards rising income inequality? Lacking consensus among scholars, this work historiographically analyzes the various explanations put forth by economic historians and labor economists over the origins of income inequality in the United States.

Simulation of the Impact of Connected and Autonomous Vehicles at a Signalized Intersection School of Engineering: Civil, Environmental and Engineering Mechanics Poster - Graduate Research

Goal 11: Sustainable Cities and Communities Goal 9: Industry, Innovation, and Infrastructure STUDENTS Hamad Bader Almobayedh ADVISORS Deogratias Eustace LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The primary objective of this study is to simulate the potential impacts connected autonomous vehicles (CAVs) may have on traffic flow and delay at a typical urban signalized intersection. Essentially, to use a microscopic traffic simulation software to test future CAV technology within a virtual environment, by examining different levels of CAVs with their associated behaviors across several scenarios to be simulated. This study is testing and simulating the impact of autonomous vehicles compared with conventional vehicles at the signalized intersection. Specifically, we are analyzing and comparing the operations of the signalized intersection when there are only conventional vehicles, conventional vehicles mixed with Autonomous vehicles, and when there are only Autonomous vehicles. Additionally, this study will show how Autonomous vehicles can improve and reduce traffic delay (congestion) by quantifying the extent the intersection can be improved. The most current PTV Vissim 11 software is being used for simulating different percentages of three different types of autonomous vehicles and conventional vehicles in the traffic stream at the intersection. There are three different levels of autonomous vehicles that are already installed in PTV Vissim 11, which are AV cautious, AV normal, and AV all-knowing. All these Autonomous vehicles are being tested in different scenarios in this study. Real data from an existing signalized intersection in the city of Dayton, Ohio are used in the PTV Vissim software simulation. The traffic count data being used in the Vissim network model are for morning and evening peak hours. Moreover, the existing signal timing data for the intersection are being used and signal timing was optimized using Synchro. The results attributes from Vissim outputs to be used to compare different scenarios are travel time, queue delay, queue length, stopped delay, and vehicle delay.

A CTC and D2D based Network Architecture for Reliable and Energy-Efficient Public Safety Communication School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

UN SUSTAINABLE DEVELOPMENT GOALS

Device-to-Device (D2D) communication, are providing more possibilities of the connectivity amongst different communication devices. For instance, CTC enables communications between heterogeneous wireless devices (e.g. Wi-Fi, ZigBee, and Bluetooth) operating in the same ISM band, and D2D communication allows direct communication between wireless devices without traversing a base station. These features make them be promising to be applied for reliable PSC network establishments. They can replace those traditional wireless communication technologies which are not specially designed for PSC networks. In this research work, we propose a novel PSC network architecture based on CTC and D2D communication technologies. To be specific, we propose a novel device clustering scheme to expand the coverage of the PSC network. Cluster heads and cluster gateways in the scheme are chosen from a group of user equipment (UE) based on particular metrics, e.g., residual battery power, received signal strength indicator, etc. Moreover, we propose a scheduling scheme for managing the UE in our PSC network to improve energy efficiency. The simulation results demonstrate that our proposed PSC network architecture can provide reliable public safety communications with high energy efficiency.

Community Engagement Project: Helping Adolescents Achieve Long-term Objectives. How does the HAALO art program benefit at-risk teens in the juvenile justice system? College of Arts and Sciences: Sociology, Anthropology, and Social Work Poster - Capstone Project

Goal 11: Sustainable Cities and Communities STUDENTS Francesca Marie Gaudio, Mitchell J Tarkany ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 This project will provide an evaluation of the associated benefits of the HAALO arts program. HAALO is an arts program created through a partnership with the Montgomery County Juvenile Court. It encourages at-risk teens to participate in the creation of artwork and to have a sense of pride in the rejuvenation their artwork brings to the urban landscape around them. Currently, juvenile justice programs often resort to probation and detention. These interventions are often counterproductive to change in behavior. Having at-risk teens participate in the creation of artwork is a unique and possibly more effective approach for dealing with at-risk youth. Our project summarizes our experience volunteering at Tejas (Teen Education & Joint Adult Studio). The population observed included convicted/at-risk juveniles in the Dayton area. This study takes an inductive approach that allows us to identify benefits as they become evident. The specific approach used in this qualitative research project is participant observation.

Goal 12: Responsible Consumption and Production STUDENTS Eric David Belcik, Connor M Dushane, Ryan Ryan Kronk ADVISORS Erin L Gibbemeyer LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The goal our project is to conduct a life cycle assessment in order to determine which writing utensil--out of a choice of wooden pencils, plastic mechanical pencils, or plastic pens--is the most environmentally sustainable. With a variety of different styles of writing utensils currently on the market, understanding which one has the best long term effects on the environment would show how the market should be headed. So many individuals every day utilize some sort of writing utensil, and so the results could signify a need for drastic change in the industry. Sustainable Development Goal number twelve, responsible consumption and production, is a guiding principle to our research in that we would like to find the most responsible choice of the three options.The research was done using a combination of the Economic Input Output Life Cycle Analysis, as well as evaluating other metrics related to sustainability. Using this hybrid style of looking at the Life Cycle allows us to evaluate the utensils from multiple angles. Overall, this issue is extremely important as there are billions of pencils and are used almost universally, and making a more sustainable choice for oneâ&#x20AC;&#x2122;s writing utensil could have a large impact on the planet.

Fully Electric Car Life Cycle Analysis (LCA) - Is the electric car truly better than a standard sedan? School of Engineering: Chemical Engineering Poster - Course Project, 201910 EGR 374 01

Goal 12: Responsible Consumption and Production STUDENTS Zachary A Connolly, scott Murphy Seel, Erik Robert Sekelsky ADVISORS Erin L Gibbemeyer LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 When Tesla first released the Model S, the first fully electric car, there were a series of academic articles released stating that over the entire life of an electric car, these vehicles are environmentally worse than a standard gasoline powered sedan. Our goal is to explore this topic and determine if these articles are still applicable. Using an environmentally extended Life Cycle Assessment (LCA), we will evaluate fully electric cars based on energy requirements, greenhouse gas emissions, and other environmental indicators. We will compare these results to an analysis of the status quo of a similarly priced standard gasoline powered sedan to determine if fully electric cars have less of an environmental impact.

Environmental Effects of Single Use Plastic Water Bottles Versus Reusable Water Bottles School of Engineering: Chemical Engineering Poster - Course Project, 201910 EGR 374 01

Goal 12: Responsible Consumption and Production Goal 13: Climate Action STUDENTS Joseph Salvatore Fraganato, Morgan Denise Henderson, Hannah Ruth Kelly ADVISORS Erin L Gibbemeyer LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 While bottled water can be more convenient on the go, these plastic water bottles contain harmful substances called polyethlene terephtalate (PET) and bisphenol A (BPA), which are both extremely dangerous to human health and the environment. The production of one plastic bottle uses energy, emits toxins into the air and uses more water to produce than actually put in the bottle for drinking. The bottles take hundreds of years to decompose, filling our landfills at an alarming rate. 38 billion water bottles end up in U.S landfills each year, which equates to about two million tons. Reusable water bottles save fossil fuels. If you were to fill one disposable plastic bottle a quarter of the way up with oil, it would represent the amount to make it. With just one person switching to a reusable water bottle, it would keep 2580 balloons of CO2 out of the air per year. If Americans were to switch to reusable, you will feel better about your commitment to the Earth!

Surface tension measurements of bio-based magnetic nanocomposites in ethanol and water solutions School of Engineering: Chemical Engineering Poster - Graduate Research

Goal 12: Responsible Consumption and Production Goal 11: Sustainable Cities and Communities STUDENTS Grace Ann Docken, Frankie Ann Petrie ADVISORS Erick Vasquez LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Separation of ethanol from water in the fermentation broth of biofuels requires a distillation process with high energy use. To reduce the energy cost of this process, emulsified bio-based superparamagnetic nanoparticles in castor oil are being studied. This work is the second step in determining the structure-property relationships for this process by evaluating the surface tension with variables of temperature and concentration which are key to emulsions formation. In this work, measurements of surface tension were taken for lignin@magnetite nanoparticles with a goniometer instrument. Magnetic and structural properties of the nanocomposites were obtained using a Vibrating Sampling Magnetometer (VSM) and Raman spectroscopy, respectively. Specifically, two studies were performed to test the effects of the magnetic nanoparticles on the surface tension of ethanol/water mixtures. The first experiment analyzed the impact of nanoparticles concentration in eight different ethanol/water aqueous solutions. The second experiment analyzed the temperature effects in surface tension at a constant nanoparticle concentration in a water solution. The lower concentrations of nanoparticles show little to no change in the surface tension; however, above 1 w/v% concentration, there is a decrease in surface tension of the dispersion. This decrease is also much higher at lower concentrations of ethanol and pure water. As temperature increases, surface tension decreased for all samples. The ultimate goal of this research is to determine the parameters in which bio-based nanoparticles can be used to create emulsions with magnetic properties for use in ethanol extraction from fermentation broths with energy-efficient liquid-liquid extractions.

Dayton Children’s Hospital Composting Initiative College of Arts and Sciences: English Poster - Independent Research

Goal 12: Responsible Consumption and Production STUDENTS Maria Elizabeth Plevris ADVISORS Rebecca C Potter LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Food composting has many benefits including addressing food waste at institutions such as hospitals. As for example, the healthcare system is responsible for 11.7 tons of waste that enters the landfills each year, some of which is due to food waste such as expired food and an overproduction of food. The food service department at Dayton Children’s Hospital in Dayton, Ohio wanted to develop a system to address food waste. Therefore, the University of Dayton collaborated with Dayton Children’s food service and dietary department to develop and implement a composting system utilizing a local composting company- Compost Dayton. The focus was on composting raw, pre-consumer produce trimmings that had not left the culinary kitchen. The process of development and implementation included: research on proper education and training techniques for the staff, creating a Higher Learning Commission (HLC) module for the staff to complete prior to training, a hands-on, in person training session, and weekly audits of the composting bin. Challenges that emerged included: maintaining proper health codes for the hospital and the composting company, along with obtaining support and adherence from the dietary staff. In conclusion, through the use of proper education and training, Dayton Children’s Hospital’s implementation of composting can help decrease food waste.

Goal 12: Responsible Consumption and Production Goal 3: Good Health and Well-Being STUDENTS Lauren Marie Murray ADVISORS Diana Cuy Castellanos LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Greenhouse gases are the driving force behind climate change with 20-30% of greenhouse gases contributed by the Western diet. Research suggests a decrease in environmental impact from food production with an overall US dietary reduction in meat and dairy and an increase of fruit, vegetable, and grains.The objectives of this study were to determine the greenhouse gas emissions of foods served in the dining halls at a mid-sized private university and to develop and implement an educational intervention aimed at behavior change. The transportation and production emissions of foods in a dining hall were determined through Clean Metrics Food Carbon Emissions Calculator. The information was translated into educational materials using a color-coded ranking system to demonstrate individual food emissions. The materials included posters, table tents and labels and were displayed for three months in a campus dining hall. Finally, a thematic analysis was employed to examine the impact of the intervention on students. Overall, consistent with existing research, animal products such as beef and lamb were found to have the highest emissions whereas plant-based products such as mushrooms and cucumbers were found to have the lowest emissions per pound of product. Themes extracted from the evaluation of the educational intervention included increased awareness and knowledge about sustainable eating but little impact on actual behavior was reported. However, this research has been utilized to create an educational program for the creation of a completely plant-based dining station in Virginia West Kettering dining hall.

Tunnel, (UD-LSWT), which simulated the drops for aerial tankers. Much effort was spent in capturing and quantifying the breakup process in a relatively low Reynolds number flow. The primary breakup of the fluid column and subsequent secondary breakup of particles emanating from the primary fluid column are the key culprits in ground pattern determination. Particle Shadowgraph imagery was utilized to study the breakup process. Frequency analysis was performed on the water jet boundaries the results of which showed that the frequency was an order of magnitude higher at the location where the structures resulting in breakup of the water jet/parent column originate in comparison to the rest of the jet extremities. Furthermore, the frequency amplitude was even higher at the location where the structures created breaks off from the parent column and creates smaller droplets. The location where the jet breaks off is also quantified in terms of the jet speed, air speed and jet diameter. All these results, along with the prospective results from the current ongoing research will be used to form a ground coverage predictive tool which will be useable by the wildland firefighting crews in order to quickly assess and control wildfires by fire retardant aerial application.

To Give Back this Piece of Earth: Cistercian Death Rituals and Approaches to Integral Ecology College of Arts and Sciences: Religious Studies Oral Presentation - Graduate Research Goal 13: Climate Action STUDENTS Scott Charles Howland ADVISORS Vincent J Miller LOCATION, TIME Kennedy Union 311, 11:40-12:00 Christian communities around the world maintain a variety of rituals that are practiced in relation to the death of one of their own members. Many of these rituals are based on theological understandings of death and resurrection, but in many cases secular norms have pervaded Christian death rituals—thus, altering their understanding of the relationship between the way they live their lives and the manner in which they handle death. One Christian community that has made efforts to preserve this connection between life and death is the Cistercian order of monks and nuns, a contemplative religious order of the Roman Catholic Church. The primary question that this project aims to answer is this: in what ways are theological concepts of death and resurrection manifest in Cistercian death rituals, and, furthermore, how do those understandings and practices influence the ecological perspectives found in Catholic social teaching? In order to examine this question, I intend to address three primary objectives, which in summary are: (1) the theological relationship between death, resurrection, and Christian ecological visions; (2) similarities and differences between ecological understandings of the inter-relatedness of living organisms and conceptions of “community” as it is defined in Catholic social teaching; and (3) the usefulness of Cistercian monastic theology and rituals related to death and resurrection as an example by which people of all faiths may learn to reorient their relationship with the natural world via death rituals that help communities understand death as a natural part of life, which is necessary for the physical and spiritual well-being of the entire ecological community in which human beings live.

Micronutrients, hurricanes, and invasive species: insights into the micronutrient limitation and stress of an invasive ant along the coast of Texas College of Arts and Sciences: Biology Poster - Graduate Research Goal 13: Climate Action Goal 15: Life On Land STUDENTS Maddie Rose Kurlandski, Ryan William Reihart ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Human activities associated with climate change are rearranging the distribution of elements and species across the globe, but the consequences of these alterations remains unknown. Coastal ecosystems are likely at risk to an increase in the intensity and frequency of large tropical storms. These storms often deposit large amounts of micronutrients, which are less abundant in living tissue, and can affect the abundance and diversity of arthropods. Little is known, though, how additions of micronutrients can affect the success of consumers, especially invasive arthropods. To determine how changes in biogeochemistry affects litter arthropods, we utilized a factorial, fertilization experiment that manipulated macro- (N&P) and micronutrients (Ca, K, and Na; 16 treatments x 8 replicates = 128 plots), in 2016 and 2017, in large 30 m x 30 m plots in a coastal tallgrass prairie near Houston, TX. We collected litter arthropods using pitfall traps in 2017, and one year post-fertilization in 2018. Based on results from 2017, we conducted feeding trials, that manipulated the ratio of Ca:Na (by 10%, 25%, and 40%) in food, on an invasive ant, Nylanderia fulva in 2018. In 2017, N. fulva was the dominant litter arthropod across all treatments, and their abundance was limited by Ca, but tends to be suppressed by Na. In 2018, however, these effects disappeared as soil cations were likely leached from the soil, and abundance of N. fulva dropped 98%, likely due to Hurricane Harvey. Preliminary lab results show that manipulating the Ca:Na ratio in the food of N. fulva affects colony fitness, indicating that Na can reach toxic levels, suppressing colony size, while Ca ameliorates these toxic effects. These results indicate that changes in micronutrient availability may facilitate the success of an invasive species, and gives insight as to how human activities are altering coastal ecosystems.

MPC for Optimized Energy Exchange Between Two Renewable-Energy Prosumers School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 13: Climate Action Goal 3: Good Health and Well-Being STUDENTS Ibrahim Aldaouab ADVISORS Malcolm W Daniels, Raul E Ordonez LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Renewable energy and information technologies are changing electrical energy distribution, favoring a move towards distributed production and trading between many buyers and sellers. There is new potential for trading between prosumers, entities which both consume and produce energy in small quantities. This work explores the optimization of energy trading between two prosumers, each of which consists of a load, renewable supply, and energy storage. The problem is described within a model predictive control (MPC) framework, which includes a single objective function to penalize undesirable behavior such as the use of energy from a utility company. MPC integrates future predictions of supply and demand into current dispatch decisions. The control system determines energy flows between each renewable supply and load, battery usage, and transfers between the two prosumers. At each time step, future predictions are used to create an optimized power dispatch strategy between the system prosumers, maximizing renewable energy use. Modeling results indicate that this coordinated energy sharing between a pair of prosumers can improve their overall renewable penetration. For one specific choice of prosumers (mixed residential-commercial) penetration is shown to increase from 71% to 84%.

Spatial Assessment of Current and Future Wildfire Risk in Los Angeles County, California College of Arts and Sciences: Geology Poster - Capstone Project Goal 13: Climate Action STUDENTS Caroline Johnstone ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 As our climate continues to change, forest fires in California are expected to increase in both size and intensity. Understanding how climate change affects the risk of wildfires is vital in protecting both the land and citizens who live in the area, as well as aiding in better wildfire management. The purpose of this project was to understand current and future wildfire risk in Los Angeles County based on natural and anthropogenic influences. This project first analyzed different factors affecting wildfire risk such as: vegetation type, land use, proximity to roads, precipitation, temperature, and wind speed. Individual risk maps are created for each of the factors for a better understanding of their spatial distribution. A final risk map was generated by adding all the risk maps using tools in ArcMap. This map helps to identify areas of highest wildfire risk under current climate conditions. The next step of this project is to incorporate projected temperature and precipitation changes by the end of the century to estimate how the intensity and spatial distribution wildfire risk will change in the future. With the expected increase in temperature and decrease in precipitation, wildfire risk is going to increase. This map provides vital information to land management officials in protecting this region of California. The final step of this project was to assess how much urban area was at risk to wildfires in both current and future conditions, and how many people live within these areas. Such information is beneficial to those in wildfire resource management and land management.

Future Impacts of Sea-Level Rise on Miami, Florida, USA. College of Arts and Sciences: Geology Poster - Capstone Project Goal 13: Climate Action STUDENTS Hannah Reid Butler ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 This project aims to analyze the impacts of sea-level rise on the coastal city of Miami, Florida. Rising temperature is causing the melting of land-based glaciers and the thermal expansion of the ocean. Both of these factors have led to sea-level rise. This will affect people living in coastal areas. Using a Geographic Information Systems (GIS) approach, this project will first identify inundated areas based on future sea-level rise projections for the year 2100. The census blocks inundated by this rise will then be analyzed based on socioeconomic factors such as race, income, and age. This information will identify any demographics being affected by these issues of climate change. This project will give insight into the affects of future climate change and give those who will be affected a chance to prepare and build resilience to these changes.

Importance of high resolution precipitation isotope datasets for climate change studies College of Arts and Sciences: Geology Poster - Independent Research Goal 13: Climate Action STUDENTS Alyssa Nicole Forristell ADVISORS Zelalem K Bedaso, Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Climate change has an unprecedented effect on the hydrologic cycle and could impact water resources. However, the link between climate patterns, atmospherics processes and water availability is poorly known. This is largely the case in a drought sensitive region of the world where direct observations of climate are limited. As conservative dual tracer, stable isotopes of oxygen (18O) and deuterium (2H) in precipitation can provide an integrated view of the hydroclimate. In Ethiopia, there is one long-term (1961-2016) monthly precipitation isotope monitoring station in Addis Ababa. However, the data from this station deviates from expectations given its inland location and high altitude, making the generalized framework usually used to interpret isotopic data in hydrology and paleoclimate studies difficult. Moreover, the reasons for these anomalously high values are poorly understood. To understand what drives these anomalously high isotope values in Addis Ababa, we analyzed 50 daily precipitation samples collected in the main rainy season (June-September 2018). Our result shows that the daily amount weighted monthly averages from this study are similar to the long-term data in Addis Ababa. The two data sets also show a similar trend throughout the rainy season with the lowest isotopic values in August. Despite theses similarities, the daily isotope measurements exhibit larger range that the long-term monthly data in Addis Ababa. Our high-resolution daily isotope dataset could provide new insights into the climatic controls on the isotopic composition of rainfall in Ethiopia and understand hydroclimate variability today and in the past.

Improvement in Jet Aircraft Operation with the Use of High-Performance Drop-in Fuels School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research Goal 13: Climate Action STUDENTS Shane Kosir ADVISORS Joshua S Heyne LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The implementation of high performance drop-in jet fuels (HPFs) from alternative feedstocks can provide economic benefits to airlines, while contributing to emissions reduction. HPFs offer several operational and economic advantages compared to conventional jet fuel, including improved specific fuel consumption and lower sooting. HPFs that exhibit high specific energy [MJ/kg] and energy density [MJ/L] can increase mission range, payload, and seat capacity. As commercial airlines in the US spend close to 135 billion USD per year on jet fuel, it follows that small increases in the specific energy and energy density of jet fuel can save airlines millions of dollars annually in fuel cost. Three approaches were taken in conjunction to bound HPF economic benefits: identification and calculation of properties for bio-derived molecules via quantum chemistry methods, utilization of ant colony optimization to determine blends of conventional and “specialty” molecules that meet HPF specifications, and simulation of flights to correlate HPF performance increases to economic benefits for airlines. Optimization indicates that alkylated cyclohexanes have significant performance benefits when used in HPFs while helping achieve drop-in operability properties. The creation of HPFs with high concentrations of mono and dicycloalkanes can potentially allow for the removal of aromatics from the fuel, which are widely accepted as being major contributors to soot formation during combustion.

(NJFCP) and JET Program are working to improve the commercialization of these alternative jet fuels. Fuel property research would aid NJFCP and JET in accomplishing their missions by increasing their understanding of figures of merit (FOM) in fuel performance, namely lean blowout, high-altitude relight, and cold start ignition due to the fuel properties. Data mining fuel properties such as viscosity and surface tension within a specific temperature range allows these programs to better understand the FOM of the fuel. Ideally, this work would reduce carbon-foot print, support surrogate development, and improve commercialization of alternative jet fuels.

Fire, Ice, Fungi, Forest: Exploring the Mesh of Relationships that Drive Seedling Recruitment in the Siberian Arctic College of Arts and Sciences: Biology Oral Presentation - Graduate Research Goal 13: Climate Action Goal 15: Life On Land STUDENTS Sarah J Frankenberg ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union 311, 3:20-3:40 Permafrost, temperature, vegetation, and fire dynamics in the Arctic compose a network of integrated feedback systems that regulate global climate. Being the epicenter of climate warming, these processes are under threat of transformation, leading to further climate implications. This ecosystem provides a global service of carbon sequestration with 35% of carbon stored in Russian boreal forests being housed in larch and with half of the soil carbon pool being stored in permafrost. The boreal forests of the Siberian Arctic are dominated by Larix cajanderi (common name: Cajander Larch). Understanding the recruitment of Cajander Larch in post-fire habitats will provide insight into future vegetation responses to climate change and reveal the level of vulnerability of carbon in the Arctic. Potential mechanisms of larch recruitment were investigated in plots of various densities of larch in post fire habitats (burn scars) in Northeast Siberia. Physical (organic layer, thaw depth) and biological factors (symbiotic root fungi colonization and symbiotic host species) were measured to examine relationships that drive larch recruitment.

Aquatic macroinvertebrate density in headwater streams with varying intensities of riparian Amur honeysuckle (Lonicera maackii) invasion College of Arts and Sciences: Biology Oral Presentation - Honors Thesis Goal 14: Life Below Water Goal 15: Life On Land STUDENTS Jenea Imani Adams, Eric Bradley Borth, Taylor Melissa Buskey, Julia I Chapman, Mitchell John Kukla, Corey Michael Kuminecz, Michelle Nicole Little, Meg Eileen Maloney, Joseph Michael Murphy, Taylor Marie Sparbanie ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union 311, 9:00-9:20 Headwater streams in the midwestern United States are an important ecosystem because they are home to key macroinvertebrate species and serve as the starting point for freshwater river systems. According to the river continuum concept, any terrestrial inputs to headwater streams can influence biotic communities and abiotic conditions downstream. Amur honeysuckle (Lonicera maackii) is an invasive shrub species prominent in the midwestern U.S. whose allelopathic properties have proven detrimental to local species biodiversity. We hypothesized that increasing Amur honeysuckle density along headwater streams would alter the diversity of aquatic macroinvertebrate communities. Five sites located in Montgomery and Miami Counties, Ohio were chosen to represent varying Lonicera maackii density along the banks of headwater streams: one heavily invaded site, two moderately invaded sites, and two reference sites (little to no invasion). A 30-meter section of stream at each site was divided into five plots that were six-meters long and were used to sample aquatic macroinvertebrates for five consecutive seasons. A dip net was moved across each plot for 60 seconds, and macroinvertebrates were then separated from the collected debris, preserved in alcohol, and brought back to the lab where they were sorted into taxonomic groups. The total number of macroinvertebrates collected did not vary greatly among sites within each season. A preliminary assessment of community composition showed that there was a greater relative abundance of Diptera and Oligochaeta at the heavily-invaded site in fall and winter compared to the moderate and reference sites. The relative abundance of Trichoptera was lower at the heavy site than the moderate and reference sites in fall, spring, and summer. Further analyses are required to understand how community composition varies among the sites and how such differences relate to honeysuckle invasion and macroinvertebrate feeding mechanisms.

Goal 14: Life Below Water STUDENTS John David Barnard, Samantha Jean Berkley, Maddi Elizabeth Conway, Audrey Allison Hayes, Emma Claire Hiltner, Madison Spooner Johnson, Suzanne L Lowes, Gretchen M Lozowski, Madeline Rebecca Norman, Emmett Justin Sheehan ADVISORS Jeffrey L Kavanaugh LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 From 2015-2017, the Miami Conservancy District and Five Rivers Metroparks completed a project to modify a low dam upstream of Monument Avenue into a kayak chute for recreational use. Low dams have negative impacts on river habitat by decreasing water velocity in the deep water impoundment behind the dam, destroying normal riffle-pool habitats, increasing sedimentation, and interfering with fish dispersion among other things. Healthy physical habitat consists of alternating pools and riffles where sediments of sand, gravel, and cobble are kept exposed by fast-flowing water. The altered conditions created by the dams are detrimental to populations of fish and macroinvertebrates whose communities are negatively impacted by the altered physical conditions. In this project, we compare the current, post-modification conditions to the pre-modification conditions in terms of both the physical habitat and communities of fish and macroinvertebrates. Fish were sampled using electroshocking techniques and macroinvertebrates were sampled with Hester-Dendy artificial substrates, kick-nets, and sweep-nets. Samples were returned to the laboratory, processed, sorted, and the number and types of organisms were recorded. Collection of specimens has occurred between the years of 2017 and 2018.

Water quality and captivity both affect the birth rate of the stingray Rhinoptera bonasus College of Arts and Sciences: Biology Poster - Independent Research Goal 14: Life Below Water STUDENTS Rachel Elizabeth Brewer ADVISORS Patrick K Williams LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Little research has been done on stingrays in captivity and in the wild, which is an important topic that I felt needed further investigation. Stingrays are marine and freshwater Chondrichthyan fishes that are commonly displayed in aquariums and zoos worldwide. While there is significant scientific knowledge of rays there is much remaining to know about these fascinating organisms. My internship at the St. Louis Zoo, allowed me to dive into the world of stingrays. Zooâ&#x20AC;&#x2122;s all over the world create their exhibits to mimic what habitats would be like for the animals in the wild. At the St. Louis Zoo, Caribbean Cove is home to Cownose and Southern stingrays. These gentle creatures have a flat body, long pointed, fins, and a long whip-like tail. The Cownose and Southern stingrays breed during summer to early fall in shallow waters out in nature. In captivity, these rays breed throughout the year. The goal of this project was to understand how captivity may influence stingray births by observing water quality and environmental control. This study evaluated the differences in the St Louis Zooâ&#x20AC;&#x2122;s pool temperature in relation to the number of births of Cownose stingrays. By evaluating the time of year that the ray pups were born in comparison to water temperature, I found that in captivity more stingrays were born in the month of May. I then compared this to other published research to see if there was a correlation between the breeding period in captivity versus the wild. More importantly, I will include all the contributing factors that may influence the Cownose and Southern stingrays breeding patterns.

Characterization of L-DOPA Containing Organic Matrix Proteins in the Eastern Oyster Crassostrea virginica College of Arts and Sciences: Biology Poster - Independent Research Goal 14: Life Below Water STUDENTS Anna Kathleen Benton ADVISORS Douglas C Hansen, Karolyn M Hansen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The eastern oyster, Crassostrea virginica, forms shell through the process of layer by layer construction. There are two components of shell: the hard layer made of calcium carbonate and the soft layer made of organic matrix. This project focuses on a specific class of proteins found in the organic layer that contain a unique amino acid, L-3,4-dihydroxyphenylalanine (L-DOPA). This class of proteins is of interest because of the crosslinking capabilities of L-DOPA. L-DOPA can adhesively bind to calcium carbonate and cohesively bind to other amino acids as confirmed by the study of L-DOPA-containing Mytilus edulis foot proteins. L-DOPA can be used as a biomarker for these proteins and can be assayed or tracked using the ARNOW assay, a catechol stain, on adductor muscle tissue. Market quality oysters were shucked, and tissue samples were collected from the adductor muscle. Proteins were extracted by homogenizing the tissue, soaking the tissue in 0.7% perchloric acid solution, precipitating proteins with cold acetone, and resuspension in 5% acetic acid. Once the initial extraction was complete,

the protein solution was concentrated using ultrafiltration under inert gas to prepare the solution to be run on a high-pressure liquid chromatography (HPLC). After HPLC separation, proteins are further characterized using acid-urea polyacrylamide gel electrophoresis. The AAA-Direct Amino Acid Analysis System was then used to determine the percentage concentrations of the amino acids present in the purified proteins. Purified protein with high L-DOPA content will be sequenced using a commercial vendor. Once the sequence is obtained, proteins will be modeled using ChemDraw, Chem3D, and Gaussian-9 software. Modeling using published sequences of putative shell formation proteins has revealed the occurrence of specific folding domains that may play a role in adhesive and cohesive binding of those proteins. We anticipate finding similar tertiary structure in proteins isolated and characterized from Crassostrea virginica.

Understanding Chemolithotrophic Reduction Mechanisms from the Dark Marine Biosphere College of Arts and Sciences: Chemistry Poster - Honors Thesis

Goal 14: Life Below Water Goal 13: Climate Action STUDENTS Anna Gwendolyn Blair ADVISORS Justin C Biffinger LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 As greenhouse gas emissions contribute to global warming and an increase in CO2 concentration in the earth’s atmosphere, the scientific community is under pressure not just to examine new technologies to reduce emissions, but also to consider the effect that increased CO2 concentration has on our terrestrial and marine ecosystems. In marine ecosystems, atmospheric CO2 dissolves and reacts with water to form carbonic acid. This diprotic acid then dissociates, contributing to a lowered pH of ocean water and affecting all levels of marine life. Fortunately, nature already has carbonate reduction mechanisms in place that can reduce the harmful effects of ocean acidification. Being able to identify individual bacteria in biological carbonate-fixing consortia can lead to adaptive systems engineered around biofilms. In this study, environmental samples taken from defined sites the dark marine biosphere (ocean depth of 2100-2300 meters) in the Gulf of Mexico were grown in a number of selective medias with defined carbonate contents. Bacterial samples were then analyzed using ion chromatography to measure carbonate consumption as a function of time. The data suggests that by selectively pressuring environmental consortia from the dark marine biosphere toward the purpose of fixing carbon, mechanisms and pathways can be generated to control the level of CO2 in the marine environment.

Bats of the University of Dayton

College of Arts and Sciences: Biology Poster - Course Project, 201880 BIO 421 P1 Goal 15: Life On Land STUDENTS Celia Montemurri ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 A total of 14 bat species have been found in the great state of Ohio. These species differ greatly, however, in their preferred diet and habitat. The University of Dayton’s campus represents a highly-developed area consisting of various large buildings, a suburban neighborhood, and some highly managed green spaces. Old River Park consists of riparian, grassy, and forest habitat. Both locations contain habitats often exploited by bats during daytime hours. These include, but are not limited to, trees, alive and dead, small openings in structures, and bridges. The range of these habitats offers an opportunity to assess differences in bat communities based on habitat preference. Using an Echometer Touch 2 Pro and an iPhone, the presence of the 14 bat species of Ohio was assessed on the main campus of the University of Dayton, as well as UD’s Environmental Research Area at Old River Park.

the presence of rare or unique species, as well as invasive species that pose a threat to biodiversity. Bill Yeck Park is a 194-acre nature park maintained by Centerville-Washington Park District and is largely surrounded by residential areas. As urban green spaces like Bill Yeck Park become more prevalent and they play an increasingly important role for the provision of ecosystem services in a postmodern, industrialized, and developed world, documenting the species composition and ecological function of these nature parks become critically important for informing management. The goal of this project is to generate list of vascular plant species for Bill Yeck Park, a large park within the Centerville-Washington Township park district. Through this work, a biodiversity inventory will be developed, critical areas for conservation will be identified, and the removal of invasive species will be strategized. Floristic surveys for this project began in March of 2017. 245 species have been identified and documented across a variety of habitats, including meadows, riparian corridors, and upland forest.

Whatâ&#x20AC;&#x2122;s going on inside grasshopper guts: the role of micronutrients in the structure of host microbiomes College of Arts and Sciences: Biology Oral Presentation - Graduate Research Goal 15: Life On Land STUDENTS Melani Muratore ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union 312, 11:40-12:00 The traditional view of terrestrial nutrient limitation has tended to focus primarily on the macronutrients, nitrogen and phosphorus, and their effects on plants and animals within terrestrial ecosystems. Experiments manipulating micronutrients have determined that when macronutrients are plentiful, micronutrients like calcium, potassium, and sodium may also be key limiting or co-limiting factors in terrestrial ecosystems. We posed the question, do microbes within host organisms respond to host nutrient limitation? We expected that microbiome diversity would decrease when no longer limited by environmental N and P. Both macro- (N and P) and micronutrients (Ca, K, and Na) were manipulated in all possible combinations (n= 70, 16 total treatments, 8 replicates, 128 plots of 30m by 30m) in a large scale fertilization experiment at a coastal tall-grass prairie in Texas. Grasshoppers were collected using sweep nets (100 sweeps/ plot). We subsequently dissected the grasshoppers and removed the gut in its entirety. The gut sample DNA was extracted and then 16s sequencing was performed to better understand the types and relative numbers of microbes in each gut sample. Statistical analysis, including Shannon and Simpson diversity, ANOVA, and NMDS determined relationships between types and numbers of microbes within the host microbiome and nutrient treatment. Grasshoppers collected in the experimental prairie treatment plots were responsive to certain micronutrients, especially sodium, with increased bacterial diversity, particularly through the appearance of rare groups. While male and female gut microbiomes were very similar in composition, different host trophic levels did correlate with different microbiome composition. These results support not only the idea that micronutrients can be limiting in prairie ecosystems, but that micronutrients may also affect host microbiomes.

Land Cover Change and Biological Invasion: Chinese Tallow Tree in Eastern Texas College of Arts and Sciences: Geology Poster - Capstone Project Goal 15: Life On Land STUDENTS Emily Elizabeth Jones ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Chinese tallow, Triadica sebifera (L.) Small (Euphorbiaceae), is one of the most pervasive invaders of in the southeastern United States. In various ecosystems, Chinese tallow forms dense monocultures, displacing native species at multiple trophic levels and potentially facilitating the invasion of other non-native species. To mitigate the spread of this species, researchers have attempted to identify areas especially prone to invasion, historically using environmental and climatic data. Recent studies suggest, however, that anthropogenic disturbance may be a powerful driver of this species invasive success. The goal of this study is to determine if Chinese tallow range expansion in eastern Texas is correlated with anthropogenic disturbance, using land cover change as a proxy. To achieve this, Chinese tallow abundance data from multiple Forest Inventory Analysis surveys (2001-2017) will be compared with historical national land cover data (2001, 2006, 2011) from 42 counties in Texas using correlation analysis. Based on existing research, we hypothesized that Chinese tallow abundance will be related to changes in land cover - correlating positively with increases in developed land, agricultural land, and forested land. The findings of this study will inform scientific understanding of the relationship between anthropogenic disturbance and speciesâ&#x20AC;&#x2122; invasions and could assist land managers in identifying areas prone to invasion by this pervasive weed.

UN SUSTAINABLE DEVELOPMENT GOALS

Goal 15: Life On Land STUDENTS Mary Catherine Lloyd, Celia Montemurri, Caroline Marie Shepherd, Taylor Marie Sparbanie ADVISORS Ryan W McEwan, Alyssa Ashley Outhwaite LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 An important first step in managing an ecosystem is discovering the biodiversity already present, to have the opportunity to bolster it, protect it, and manage for it. One way to document biodiversity is to perform a BioBlitz. A BioBlitz is an event where a group of people, usually including volunteers, aid a research group in identifying all species of living things in a certain area. During the one semester, or approximately four months, of this project the lab team focused on identifying certain categories of species. The Environmental Research Area is approximately 60-70 acres and surrounded by a moat-shaped lake. The research team focused on birds, plants, insects, mammals, and trees. Other categories are included in a master plan to be completed in the future. 104 species were identified in total within the set taxa. Many factors, such as time and resource constraints, contributed to the lower numbers of identification for other major groups of organisms. With further surveying to compile a more complete list of species, this list can serve as a useful tool in making management decisions to best protect the natural inhabitants of Old River Park, the Great Miami River, and Dayton.

Alien tree’s sugary SOS exploited by thieving tramp ant: unidirectional benefit in a tritrophic mélange College of Arts and Sciences: Biology Poster - Graduate Research Goal 15: Life On Land STUDENTS Emily Elizabeth Jones, Natalie Christina Martin ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Triadica sebifera (Euphorbiaceae), a centuries old invader of southern ecosystems, was virtually free from natural enemies until the specific, hypermetamorphic moth Caloptilia triadicae (Lepidoptera: Gracillariidae) appeared in 2004. Simultaneously, populations of the destructive tawny crazy ant, Nylanderia fulva (Hymenoptera: Formicidae), spread cospatially across the southeast. To examine potential interactions among these species, we sought answers to these questions: 1) does Caloptilia induce extrafloral nectar production in Triadica; 2) does N. fulva consume nectar, larvae, or both; and 3) does N. fulva provide indirect defense to the tree, or to its attacker? To understand these interactions, and their implications for southern ecosystems, we conducted a series of lab, greenhouse, and field experiments in coastal Texas.In response to herbivory by Caloptilia, potted Triadica saplings strongly induced extrafloral nectar production. Percent leaf damage explained 57% of the variation in cumulative nectar volume (p<.0001), and nectar volume on saplings with >20% of leaves damaged was significantly greater than on controls (p=0.0005). Nylanderia fulva exploited available nectar resources without attacking Caloptilia larvae. On potted saplings, nectar volume was significantly lower when ants were present (p=0.008), while no differences were observed in Caloptilia survivorship (p=0.56). Likewise, no differences in Caloptilia abundance or parasitism rates were observed when ants were excluded from naturally recruited Triadica saplings (p=0.97;p=0.8). Large Caloptilia infestations reduced trunk elongation in Triadica saplings (R2=0.32, p<.0001), but had no effect on leaf production, biomass, or survivorship. Because Triadica saplings supplied N. fulva workers a carbohydrate resource while sustaining heavy damage, and because neither Triadica nor Caloptilia benefited from worker foraging, N. fulva was the only beneficiary in this alien, tritrophic interaction.

After analyzing the sequencing results, we identified two fungal phyla that were present in all samples: Ascomycota and Basidiomycota. Within Ascomycota, the class Dothideomycetes is most prevalent. Within Basidiomycota, the classes Tremellomycetes and Ustilaginomycetes are most prevalent. Dothideomycetes are typically found as saprobes, or decomposers, that break down dead leaf matter. They are also commonly found on living plants, acting as pathogens or endophytes. Tremellomycetes are a type of pathogenic fungus that acts as a parasite toward insects and plants. Ustilaginomycetes, known as â&#x20AC;&#x153;smut fungi,â&#x20AC;? act as a parasite toward vascular plants. All of these classes of fungi are directly involved with plant matter. Further statistical investigation will be done to determine the drivers of the diversity of these fungal communities and their significance.

The Prickly Problem of Pears: Potential effects of native orthopteran herbivory on an invasive woody plant College of Arts and Sciences: Biology Poster - Honors Thesis Goal 15: Life On Land STUDENTS Kaitlin Marie Gawkins, Tara Brianna Masthay ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Across the United States, land managers are struggling to cope with a relatively new invasive species, Callery pear (Pyrus calleryana). At the present, Callery pear is one of the most important invasive species threatening prairies and early successional habitats in Ohio and the Midwest, and yet, there is no viable means of control that is widely used for this species. This is due to the fact that this species is resistant to herbicides and resilient against prescribed cutting/burning. One potential management strategy of invasive species is biocontrol, or the intentional introduction of natural enemies to control the growth and propagation of a target organism. Previous experiments with Callery Pear have been limited herbivory by large animals, thus, an important knowledge gap exists in the interactions between native insect herbivores and the woody plant. In order to explore this knowledge gap, we conducted a month-long field enclosure experiment where we manipulated the species richness of native orthopterans in enclosures with either a Callery Pear sapling or a similar native tree sapling, American Basswood, and destructively measured the biomass of the tree and vegetation in each enclosure. We then calculated the percent change in biomass between the treatments and controls to determine if varying the orthopteran species richness had any effect on plant growth. We found that in treatments with a high species richness of orthopterans, there was a larger positive percent change in Callery Pear biomass. This was opposite to what we expected due to the fact that, traditionally, a higher diversity of herbivores would lead to an increase in herbivory and thus a decrease in biomass. This should be studied further in order to understand how intentional reinstatement of insect diversity to early successional areas by environmentalists may actually be helping invasive species to grow more rapidly.

Tiny Green Grasshopper Pharmacy: Does Antibiotic Treatment of Buckwheat Grasses Impact Orthopteran Eating Habits? College of Arts and Sciences: Biology Poster - Independent Research Goal 15: Life On Land STUDENTS Emily Elizabeth Jones, Troy Harry Lampenfeld, Olivia Margaret Pettigrew ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Antibiotics are extremely prevalent in modern medicine and are used in treatment of a multitude of bacterial infections and diseases. As such, humans are increasing the abundance of antibiotics in many natural systems, especially those close to range-land systems where cattle are often prophylactically treated with antibiotics. Increases in antibiotics could be detrimental to organisms, such as herbivorous insects that need to maintain their microbiota to help break down their food. A small choice experiment was conducted to determine the effect of the antibiotic tetracycline on the dietary habits of Chortophaga viridifacsiata (Orthoptera: Acrididae), a species of grasshopper native to Ohio. The results of this experiment did not yield significant evidence that C. viridifacsiata show dietary discrimination between grasses treated with tetracycline and grasses grown under normal conditions. However, there was a trend towards reduced feeding on plants grown with antibiotics, which could be important given the small sample sizes of this study. Future experiments will include a wider array of antibiotic treatments as well as multiple species of grasshoppers. If the antibiotic enrichment of these ecosystems is causing changes in herbivory patterns among arthropod communities, it could be impacting arthropod and plant community structures depending on which species of plants are taking up these antibiotics.

Insectile Neurochemistry: Developing a novel HPLC-based method to assess neurotransmitters in the grasshopper brain College of Arts and Sciences: Biology Poster - Independent Research

UN SUSTAINABLE DEVELOPMENT GOALS

Goal 15: Life On Land STUDENTS Benjamin Klocke ADVISORS Pothitos Pitychoutis, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Grasshoppers (Order Orthoptera) are critical members of grassland ecosystems; as herbivores they serve an important role in many ecosystem services. They can also cause very costly destruction of crops and are seen as pests in agriculture. Therefore, understanding grasshopper behavior is critical to fully understand their impact on the environment. Many chemical pesticides and fertilizers used in agriculture affect the balance of micronutrients such as sodium (Na) and calcium (Ca). Similar micronutrient shifts have recently been correlated to an alteration in grasshopper activity. It is currently hypothesized that changes in neurotransmitter systems in the grasshopper CNS underly this response. Therefore, understanding the neurochemical mechanisms underlying these observed behavioral changes is necessary to fully understand the impact of chemicals used in agriculture. However, only a few studies have assessed neurotransmitters have not been quantitatively assessed in insects. Thus, the purpose of this project was to develop a novel HPLC-based method to assess neurotransmitters in the grasshopper brain. This method will be used in collaborative projects by the Prather and the Pitychoutis labs here at the UD to conduct studies exploring grasshopper neurotransmission dynamics following micronutrient shifts in the ecosystem.

The Buzz Around Solar Energy: How pollinators could be affected in an urban prairie located under a solar array College of Arts and Sciences: Biology Poster - Independent Research

Goal 15: Life On Land Goal 7: Affordable and Clean Energy STUDENTS Marigrace Sandi Moses, Francisco Jose Suarez Negron ADVISORS Leah J Ceperley, Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Nonrenewable resources are approaching obsolescence as communities look towards the future and sustainability. Solar energy has been a hot topic, but there is concern about the structures taking over habitats and disrupting the ecosystems they will share. As solar energy, specifically ground solar, becomes more prevalent in communities, the worry of preserving land and habitats increases particularly for lepidoptera (moths and butterflies) and hymenoptera (bees and wasps). This concern is based on the simple fact that renewable energy sources need more area to be effective. This research will examine how the installation of solar panels could affect how frequently pollinators visit a prairie. We observed the number of different pollinators that visited Solidago riddellii and Ageratina altissima which are both prairie plants native to Ohio. Since the prairie had not been seeded yet, 60 mason jars with the prairie plants were placed outside of and underneath the rows of solar panels. The jars were left out for about 24 hours. During this time, an observer recorded pollinators that landed on the flowers.This experiment started late in the flowering season and we did not get sufficient data to answer these questions. However, the ground has been cleared and seeding has now taken place. Since the prairie will be growing by Fall 2019, further observation will take place to test the central question in this study. Continuing this study could help many communities plan for thriving pollinator communities as they begin to install ground solar panels. While renewable energy is crucial, it is important to consider the ecosystem that they are being introduced to and how they might affect target organism of restoration.

colonize these sites. Sweepnet samples (100 sweeps per site) were taken at 5 constructed prairies and 5 remnant prairies in 2017, and 7 constructed prairies and 6 remnant prairies in 2018. All arthropods were sorted to order, and some orders to morphospecies. We saw that in 2017, Coleoptera (beetle) abundances were higher in remnants compared to constructions (p=0.04). In particular, Phalacridae (shining flower beetles) could be possible indicator species for restoration in prairies. Preliminary data from 2018 shows that the number of Phalacridae increases with the age of the constructed site (R²=0.47). These results suggest that insect communities are different in the two prairie types and certain species of arthropods are not being restored in one or two years, but rather over long periods of time as late-successional species are able to colonize. These results could have large implications on how tallgrass prairies are restored and managed, and how these ecosystems should be assessed for restoration.

Hurricane Harvey hits the prairie: how are grassland insect communities affected by a hurricane? College of Arts and Sciences: Biology Poster - Independent Research Goal 15: Life On Land Goal 13: Climate Action STUDENTS Bridget Marie Caffrey, Emily Elizabeth Jones, Ryan William Reihart ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Although hurricanes are pervasive disturbances along the Gulf Coast, we know little about how they affect the organisms living in rare coastal tallgrass prairie ecosystems. We especially know little about how they affect organisms other than plants, especially insect communities that are crucial to prairie functioning. Hurricanes cause flooding and deposit lots of marine-derived nutrients; both of these effects could greatly affect insect composition. We predicted that insect communities would have greater effects on litter insects than aboveground insect communities, and that overall insect abundance would be lower after a hurricane. We sampled insects in the litter by pitfall traps and aboveground vegetation by sweep-netting both before (litter=1 year pre-hurricane and aboveground vegetation=2 years pre-hurricane) and after Hurricane Harvey that hit our field site in 2017. We found that insect abundance was lower in the litter and aboveground after the hurricane, and that the composition of insects in the litter and aboveground was very different after the hurricane hit. We hope to test in the future whether effects on insects are driven by flooding versus the deposition of marine-derived nutrients. As hurricanes are predicted to grow in intensity and frequency, the results of this experiment are very important in managing insect communities in these rare ecosystems.

From Putt Putt to Prairie: A Hole-in-One for Ecological Restoration College of Arts and Sciences: Biology Poster - Course Project, 201880 BIO 479L P1 Goal 15: Life On Land Goal 4: Quality Education STUDENTS Sara Marie Brunner, Erin Nicole Ferrell, Drew Daniel Gojsovich, Alex Everitte Newman-Caro ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 This study was designed to be a vital stepping-stone in the long-term ecological restoration of Old River Park, located in Dayton, Ohio. For over fifty years, this park served the public and inevitably became a significant part of the Dayton community. Nestled within the park is a deserted Putt Putt course that has been consumed by invasive plants such as Callery pear (Pyrus calleryana) and honeysuckle (Lonicera maackii). Due to the lack of natural predators, these plants actively inhibit the growth of other native species by outcompeting them for vital resources such as sunlight and water. This has ultimately led to a detrimental decrease in native plant biodiversity. The objective of this project was to restore the course by first clearing and controlling the invasive plants. A trial-and-error process was utilized to determine individualized methods of removal. Spaded shovels were best-suited for removing Callery pear, while clippers were best-suited for removing honeysuckle. To re-enforce the natural competition within the area, the team visited different sites within Old River Park and collected native prairie plant seeds. Species included pokeweed (Phytolacca americana), white snakeroot (Ageratina altissima), goldenrod (Solidago), and wingstem (Verbesina alternifolia). The team collected no more than twenty percent of seeds from each population to ensure phenotypic diversity and genotypic variability. These seeds were then dispersed within the cleared areas of the course. Ultimately, the group was able to remove invasive species from fourteen of the eighteen Putt Putt holes. As a continuing project, further results are pending based on the re-growth of invasives during the spring, summer, and fall of 2019. The team also worked with other students and Dayton community professionals to produce a long-term vision and restoration goal for the site. Native plants will be seeded at each hole of the course based on sunlight and nutrient availability, conclusively producing a “native prairie garden walk” for public education and enjoyment. This research is important because it will allow University of Dayton students to understand the importance of native ecology and the substantial impact that humans can have on natural environments.

Goal 15: Life On Land Goal 11: Sustainable Cities and Communities STUDENTS Emily Ann Rickert ADVISORS Patrick K Williams LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Bees are an essential part of human life as they provide important pollination to manycrops used for food while also promoting flowering plant growth. Within the urbansetting there are places that keep this in mind and attempt to conserve bee populationby planting native species of plants, just as parks plant bee-friendly flowers, andurban gardens use vegetables and flowers known to attract bees. Urban gardens workto provide vegetables and organic produce to communities in order to alleviate foodcrisis and subsequently also grow pollinator-friendly food. This study focused onwhether the biodiversity of bees, wasps, hoverflies and other significant pollinatorsare being affected by these different types of urban land use and their resourceavailability. Urban gardens and restoration efforts were therefore used to gauge how human manipulation of the environment in certain urban areas can possibly changehow pollination occurs.

GIS-Based Habitat Suitability Analysis for the Eastern Hellbender College of Arts and Sciences: Geology Poster - Capstone Project Goal 15: Life On Land STUDENTS Emma C Yanosko ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The Eastern Hellbender is North America’s largest amphibian species and is in great danger of extinction. A good understanding of its spatial distribution is very important because the species is a biological indicator for good water conditions. Keeping this vital species off the endangered list is advantageous for preserving biodiversity in our streams. The aim for this project is to determine the most suitable habitat range for the Eastern Hellbender based on the factors that most affect its distribution. First, we will identify the most significant factors that are affecting the population of the hellbender. The six factors chosen are as follows: land cover, elevation, slope, water temperature, water pH, and proximity to dams. A suitability map will be created for each of the criteria. All of the six suitability maps will be overlaid to create a complete suitability map. This suitability map will then be compared to the actual current species range of the Eastern Hellbender so that its accuracy can be assessed. This information could provide insights into the species dynamics, as well as the design of protection plans and conservation strategies.

Wildfires and Regeneration in Larch Forests of Northeastern Siberia College of Arts and Sciences: Biology Oral Presentation - Graduate Research Goal 15: Life On Land Goal 13: Climate Action STUDENTS Eric Bradley Borth ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union 311, 3:40-4:00 The Arctic is warming at an alarming rate, a phenomenon which has been causing more frequent and severe wildfires in boreal forests. The Cajander larch (Larix cajanderi) forests of Siberia are particularly important because they cover an immense area of carbon-rich permafrost soil, one of the largest terrestrial carbon sinks. The fate of this belowground carbon is intimately tied to the structure of these larch forests. Due to the fact that forest structure is largely determined by the establishment of new seedlings after a fire, we seek to learn more about how these changes in fire regimes may change the factors that drive seedling establishment. We examine 6 Cajander larch stands in northeastern Siberia that have been burned in the past 15 years. We evaluate the importance of microsites that favor larch establishment (deemed “safe sites”), a concept that has been anecdotally recorded, but not rigorously studied. We analyze the strength of seedling preference by comparing the percentage of seedlings that establish on safe sites to the percentage of the area that is covered by safe sites. This analysis is being carried out in burned sites with varying seed availability to determine whether seed limitation affects safe site preference. The results indicated that safe sites were indeed preferentially colonized by larch seedlings. This effect was stronger in sites with greater seed limitation. The preference for safe sites was also stronger in lowland/floodplain sites, which may be due to the differences in types of safe sites that are predominant in lowland versus upland sites. By synthesizing these results regarding seed production and seedling establishment, we can better predict the success of reforestation after wildfires which influence the future trajectory climate feedback loops.

The Child’s Voice as a Narrative Critique in African Ex-Child Soldier Memoirs College of Arts and Sciences: English Oral Presentation - Graduate Research

Goal 16: Peace, Justice, and Strong Institutions Goal 10: Reduced Inequalities STUDENTS Julius Maingi Muthusi ADVISORS Thomas A Wendorf LOCATION, TIME Kennedy Union 312, 1:20-1:40 African Ex-Child Soldier Memoirs to some extent have been viewed as humanitarian texts that raise sympathy or even funds from readers to enhance child rights initiatives. Such initiatives have been noble and worthy. However, my literary analysis research goes beyond the humanitarian reception, to examine how the use of the child’s voice functions as a narrative critique of a distorted adult world. Exploring Ishmael Beah’s A Long Way Gone and Senait Mehari’s Heart of Fire, I examine how these authors employ a blend of aesthetic invention and remembered and experienced history inherent in the child’s voice within their narratives. I use Historical Research and Post-Colonial, Trauma and Gender Theories for my literary analysis. My interpretive work involves tracing the political, social and economic histories of authors’ native spaces; examining functions and effects of child narrators; and understanding memory reconstruction paradigms and the functions of storytelling in confronting trauma. My literary analysis reveals that the child’s voice points to underlying forces of historical, political and economic exploitation, and marginalization. Displacement, Social Injustice and Trauma are the major themes arising from my research. All these themes indicate irresponsible adult-led national, international, socio-political and economic networks and practices. Through the capacity of the child’s perspective to cross taboo lines and the adult shame frontier, and to penetrate emotional danger zones easily, my research shows that the child’s voice exposes how adults within child soldier spaces and beyond, are flawed and limited by their participation in social, cultural and ideological institutions and discourses.

where their allegiances lie. Are they dedicated to the preservation of America and its people or just in protecting their own self interests? These questions are answered in the seven-episode audio drama, Echo Protocol. How does a podcast come to be? Tracing from inception to final edits, one can see how a podcast moves from small idea to a full-fledged mini-series. Focusing on themes of power, corruption, and the corruption of American politics, Echo Protocol attempts to answer why we choose to place certain people in positions of great power and responsibility. Hearing from the creator, actors, and the audio engineer, the story of Echo Protocol is brought into view not only as a creative endeavor but also as a reflection of our current social and political climate.

The effect of a counterfactual mindset induction on jurors’ evaluations of eyewitness evidence College of Arts and Sciences: Psychology Poster - Independent Research

Goal 16: Peace, Justice, and Strong Institutions STUDENTS Alex Jordan Reynolds ADVISORS Dario Norman Rodriguez LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 We tested whether inducing participants to think counterfactually about a case involving eyewitness evidence would sensitize them to variation in eyewitness evidence quality. Participants read an abbreviated transcript of a murder trial in which the quality of witnessing and identification conditions was manipulated. A counterfactual mindset induction manipulation was embedded in the defense’s closing arguments. Participants rated eyewitness evidence as weaker, and voted guilty less frequently when the witnessing and identification conditions were poor. The predicted interaction effects did not emerge.

Inevitable or Avoidable: Assessing the Relationship between Childhood Trauma and Adult Crime and Violence College of Arts and Sciences: Sociology, Anthropology, and Social Work Poster - Capstone Project

Goal 16: Peace, Justice, and Strong Institutions STUDENTS Chloe Marie Kisela ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Crime, violence, and childhood trauma are all unfortunate things to speak of, yet they are ever-present in our society. We might have several questions about what factors have a casual influence on these events and how we can prevent them, but for the researcher, one question stood out among others – could all three be connected in some way? In conjunction with that thought, this project uses secondary data analysis to examine whether or not childhood trauma (neglect, abuse, parental death, parental absence, etc.) is related to later adult criminal offending or violent behavior. In addition, specific psychological processes that could possibly connect childhood trauma with adult offending have been researched and described, including learned helplessness, classical conditioning, neurological changes in the brain post-trauma, and the emergence of psychological disorders. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) has been utilized through statistical analysis in pursuit of supporting or refuting the hypothesis, which believes that there is a positive relationship between childhood trauma and adult offending. This is all done with the motive to help reduce childhood trauma and adult offending and violence because, in order to pursue the weighty goals of putting an end to crime as well as childhood suffering, we must first work to better understand them and how they relate to each other.

Goal 16: Peace, Justice, and Strong Institutions Goal 4: Quality Education STUDENTS Emily Katherine Dotson ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 Many institutions of higher education are finding the likelihood of students returning to the university after a disciplinary suspension is somewhat higher than in past decades. Students who return have different stories and experiences that are important to any reintegration to a community. Restorative Justice practices can play a large part in making someone feel accepted, forgiven, and allows for rebuilding relationships. Between work done in prisons or in K-12 schooling, reintegration programs can look extremely different. Through semistructured interviewing four (4) students at the University of Dayton who have successfully reintegrated to the community, I explored their perspective on what is most and least helpful during their reintegration experience. Results show that having a reintegration program significantly aided students in feeling more welcomed back to campus and ensured that they continued on a path for success concurrent with their personal goals. In future practices, schools should create a reintegration program that is more uplifting and positive such as Restorative Justice Practices, versus a punitive approach causing a further decline in student and staff relations. Having support and resources readily available at the beginning has shown to be the most beneficial for returning students.

Perceiving Place: A Social Design Case Study College of Arts and Sciences: Art and Design Poster - Honors Thesis

STUDENTS Annie Anne Brinkman ADVISORS Misty K Thomas-Trout LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Space is one of the most basic foundational systems for living things. No matter what happens in the world, it happens in a spatial setting. The specific design of that setting or place plays a large role in the lives of those within it. Other factors within place—factors that might inform design choices—also affect perception of place. Broad consensus exists in scholarly literature about the general role that history, culture, environment and social factors play into the perception of place. However, a confirmatory analysis of this model, especially in regards to the specific categories influencing perception, has yet to be conducted. Therefore, the purpose of this study is to expand upon and further explore the notion of such categories in space analysis. I am looking to find if the application of this method will reveal varying differences in internal and external perceptions, and the level to which they may or may not vary. I am interested in further exploring the ways in which such knowledge can then lend itself to the creation of more informed and effective neighborhood-based design, especially centered on bridging potential gaps in understandings of place with Dayton, OH. It is hoped that this research will educate not only designers, urban planners, and community leaders, but also the broader public as to what is affecting the spaces they are functioning within. Success with this approach will provide a powerful social model for advancing communication across various levels of perception, as well as cultures and languages.

Antibiotics were first discovered accidentally in 1928 and then purposefully synthesized to help combat bacterial infections. In the relatively short time since their discovery, many bacterial species have developed resistance mechanisms to these antibiotics. Due to the ability of pathogens to rapidly proliferate, beneficial mutations to increase their fitness in their environment have helped pathogens respond to antibiotics relatively quickly. The importance of discovering novel antibiotics to combat resistant strains is increasingly important. The Small World Initiative utilizes student researchers across the world to isolate new antibiotics to combat the intensifying antibiotic resistance dilemma. The goal of this research is to use bacteria isolated from soil to test their antibiotic producing abilities against a variety of previously known antibiotic resistant pathogens, termed ESKAPE pathogens. The gram-positive pathogen, Enterococcus faecium, specifically demonstrates antibiotic susceptibility to a few of the soil isolates. The susceptibility is confirmed by zones of inhibition which indicate that the isolate is producing antibiotics to which E. faecium is not yet resistant. The isolates that exhibit antimicrobial activity against the pathogens will be identified through a process of Gram staining, catalase testing, and other biochemical tests. The purpose of these tests is to identify new antibiotics that can be used to help combat antibiotic resistant pathogens.

STUDENTS Michelle Lynn Borchers ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Antibiotics have become a problem as their overuse has led to pathogens resisting the effect of antibiotics. This is an important health matter as once effective antibiotics no longer work to cure some illnesses. The Small World Initiative and the Tiny Earth Network function to discover potential antibiotics in nature by isolating bacteria from soil samples in the environment and testing them against ESKAPE pathogens. The goal of this research is to help support the Small World Initiative by testing soil for the presence of naturally occurring antibiotics on the University of Dayton’s campus. A sample of soil was collected from a backyard on campus grounds and tested against ESKAPE pathogen safe relatives Enterococcus faecium and Enterococcus raffinosus. Antibacterial effects can be quantified by measuring the zones of inhibition on the agar plates. Lab techniques such as aseptic technique, serial dilution, master plates, and spread plates were used to isolate the pure bacterial colonies that showed antibacterial effects on the pathogens. Gram staining and biochemical testing were performed to try to identify the bacterial isolates. The biochemical tests include: catalase, hemolysis, triple sugar iron, mannitol salt agar, MacConkey agar, citrate, gelatinase, and motility. The antibiotic producing chemicals of the pure colonies were then extracted and tested with eukaryotic cells. The findings will help contribute to the mission of the Small World Initiative and the Tiny Earth Network.

Discovering Antibiotics from UD's Soil College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05 Goal 3: Good Health and Well-Being STUDENTS Jackie Nicole Petrichevich ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The discovery of antibiotics has helped humans survive many diseases that were once deadly. But with the overuse of antibiotics in the medical field, some “superbugs” have evolved resistance to multiple antibiotics we utilize. The Tiny Earth Network and Small World Initiative have started a coalition of undergraduate students to help discover new antibiotics from different soils around the world. Over the past semester, I have been doing research to find microbes from soil outside of the Adele Center that has antimicrobial effects on known pathogens. This work is important because it could lead to the discovery of new antibiotics that can kill pathogens affecting humans. The bacteria that was collected was tested against the pathogens Acinetobacter baylyi and Enterococcus raffinosus to determine how efficient the antimicrobial properties were. Gram stains and biochemical tests were then used to help identify and characterize the bacteria we were working with. From there, I isolated antibiotic compounds and tested them against pathogens and eukaryotic cells. Overall, this work helps to support the Tiny Earth Network and Small World Initiative and will, hopefully, help to resolve the antibiotic crisis we are currently having.

Goal 3: Good Health and Well-Being STUDENTS Erin Elise Pellot ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Within recent years there has been a rise in the number of antibiotic resistant bacterial strains. These resistant strains have no known treatments and thus pose a threat to society. Bacterial strains form resistance by evolving past the mechanisms behind a given antibiotic. With bacteriaâ&#x20AC;&#x2122;s unrelenting ability to evolve and adapt there is an ever present need for new antibiotics. To relieve this need, the Tiny World Initiative was formed to provide students the chance to conduct antibiotic research in the classroom setting. For this in class research experience, an on-campus soil sample was collected and analyzed for possible antibiotic producing microbes. After cultivating and selecting bacterial colonies, samples were tested against two pathogen safe relatives of the ESKAPE pathogens. ESKAPE is an acronym to describe the six most antibiotic resistant opportunistic pathogens which pose a threat to society. The ESKAPE relatives tested against in this experiment were Pseudomonas putida and Staphylococcus epidermidis. After finding seven antibiotic producing colonies the samples were put through multiple classification tests which include a gram stain, catalase test, hemolysis, triple sugar iron, mannitol salt agar, MacConky agar, citrate, gelatinase and a motility test. After classifying the samples they were tested against Eukaryotic cells in the hopes of finding a safe antibiotic treatment.

Interaction of key inflammatory pathways in the tumor microenvironment in Drosophila cancer models control tumor progression College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Kirti Snigdha ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The interaction between the tumor cells and the surrounding normal cells constitutes the Tumor microenvironment (TME). The Toll-like Receptor (TLR), Jun N-terminal Kinase (JNK), and Tumor Necrosis Factor (TNF) produce inflammatory components in the TME, and are thought to play a critical role in tumor survival and progression. However, the exact nature and mechanism of interactions within the TME remain poorly understood. These core inflammatory pathways are conserved in Drosophila. As 90% of tumors are epithelial in origin, we used a epithelial tumor model in the wing imaginal discs of Drosophila melanogaster to study the interaction of these key inflammatory pathways in the TME. We established a new TME model by creating FLP-out clones of oncogenic forms of Yki or RasV12 in polarity deficient (scribble mutant) cells marked by GFP surrounded by normal cells. These mosaic clones allow us to test changes in intercellular and signaling interactions within the tumor, surrounding its microenvironment and in distant normal cells. We studied the activity of TLR, TNF and JNK pathway using immunohistochemistry. We found that Drosophila IÎşB Cactus (TLR component) and activated form of JNK (p-JNK) were

induced in the tumor cells whereas levels of Drosophila TNF ligand, Eiger were unaffected in both the tumor and the surrounding normal cells. We hypothesized that crosstalk between these key pathways in the TME promotes tumor survival and progression. The genetic epistasis experiments between JNK and TNF revealed that downregulation of the TNF receptors in the tumor does not affect the metastatic abilities of the tumor cells. However, similar experiments between JNK and TLR showed decrease in invasiveness of tumor cells likely due to downregulation of Cactus in the tumor cells. We are currently testing if TLR, TNF and JNK pathways genetically regulate each other or independently affect the TME to control tumor growth. Our research will help to unravel the correlation between inflammatory pathways and tumor progression in an in vivo model.

STUDENTS Prajakta D Deshpande, Brent O Mcginty ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 As the most common progressive neurodegenerative disorder, Alzheimer’s disease (AD) has been predominantly found in people 65 years of age or older. AD is associated with a gradual decline in cognitive impairment and memory as well as effects on behavior and decision making. AD is also responsible for the most dementia cases in elderly people. As per the Alzheimer’s Association facts, over 5 million Americans were affected by AD in 2018 whereas the number is predicted to rise to approximately 14 million in 2050. One of the causes of AD is mis-cleavage of the transmembrane protein called amyloid precursor protein (APP) by the enzymes β-secretase and γ-secretase, resulting in accumulation of amyloid beta-42 polypeptide (Aβ42). These amyloid beta peptides aggregate into hydrophobic plaques in the extracellular region in the brain, altering the cellular pathways and resulting in neuronal death. In this study, we have used Drosophila as a model system and misexpressed the human Aβ42 in the photoreceptors of the Drosophila eye. The misexpression of the Aβ42 in the Drosophila eye triggers the neuronal cell death resulting in a glassy reduced eye phenotype. This study focusses on how microRNA mir-277 regulates the Aβ42 mediated neurodegeneration. MicroRNA regulate the gene expression post-transcriptionally and repress the protein formation by sequence-specific degradation of target mRNA. Earlier studies have shown the association of microRNA in AD and the role of mir-277 in AD is not clear. This study adds to our understanding of the role mir-277 may play in Aβ42 mediated neurodegeneration and its potential role as a biomarker for AD.

Role of Lunasin in Alzheimer’s disease College of Arts and Sciences: Biology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Steven Gerard Borchers, Prajakta D Deshpande, Neha Gogia ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alzheimer’s disease (AD), a common form of dementia and age related progressive neurodegenerative disorder, manifests as memory loss and reduced cognitive ability. One of the hallmarks of AD is the formation of the Amyloid-beta 42 (hereafter Aβ42) plaques, which triggers oxidative stress due to aberrant signaling and finally results in the death of neurons. However, the exact mechanism causing cell death is still not well understood. We misexpressed high levels of human Aβ42 protein in the developing fly retina, which mimics AD-like neuropathology. Recently, we found that a plant protein Lunasin can ameliorate Aβ42 mediated neurodegeneration in the eye by blocking c-Jun N-terminal kinase (JNK) signaling pathway. It is known that Immune deficiency (IMD) pathway, Nuclear factor-κB (NF-κB) signaling pathway, Toll receptor pathway and JNK pathway crosstalk with each other in neurodegeneration. Here we test the role of IMD and NF-κB pathway in Aβ42 mediated neurodegeneration. Loss of function of Relish (Rel), a member of and NF-κB and its downstream gene- Diptericin rescues the small glazy eye phenotype. Our working model is that Lunasin might down-regulate JNK signalling pathway which in turn downregulates IMD pathway to ameliorate Aβ42 mediated neurodegeneration.

Role of Relish/NFkB Apoptosis Pathway in Amyloid-beta 42 mediated neurodegeneration in Alzheimer’s disease College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Steven Gerard Borchers, Prajakta D Deshpande, Neha Gogia ADVISORS Amit Singh LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Alzheimer’s disease (AD), is a neurodegenerative disease which affects mental functions of the patients. This disorder progresses with age and does not have a cure to-date. One of the reasons for the manifestation of AD is the accumulation of amyloid-beta-42 (Aβ42) proteins. In our study, we have used Drosophila as our model organism (as 75% of the genetic machinery is conserved between flies and humans), and have developed a model where when human Aβ42 is misexpressed in the differentiating eye, it triggers cell death in retinal neurons of the eye. We have identified that Lunasin (a soy-based anti-inflammatory protein), can block Aβ42 mediated cell death and thus wanted to test whether NFkB pathway (anti-inflammatory pathway, lead to translation of apoptotic proteins of jun-N Terminal Kinase, JNK pathway), helps lunasin blocking cell death. In order to test this, we developed transgenic flies which can produce human Aβ42 and Aβ42+Lunasin in Drosophila eye and checked the effect of modulating NFkB pathway in this background. Our hypothesis states that manipulating the levels of Relish (component of the Imd-NFkB pathway), could lead to activity variation in JNK pathway in Aβ42+Lunasin flies. To test our hypothesis, we used GAL4/UAS system genetic technique and misexpressed Relish and RelishRNAi in human Aβ42 and Aβ42+Lunasin background and checked for the resultant phenotypes in (1) larval eye discs and (2) adults. Our data shows that downregulation of Relish interferes with Lunasin’s ability to rescue Aβ42 phenotypes and thus leads to eye suppression phenotypes, which suggests that Imd-NFkB pathway plays a positive role in Lunasin’s ability to mitigate the neuronal cell death cause by the accumulation of Aβ42 plaques. These studies have significant bearing on the use of NFkB members as biomarkers or druggable targets and generate new insights into the mechanism by which Aβ42 mediated neurodegeneration cell death can be blocked in future.

STUDENTS Elizabeth Claire Sinnathamby ADVISORS Carissa M Krane LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Cope’s Gray Treefrog, Dryophytes chrysoscelis, seasonally tolerates freezing. During this process, it is subject to cellular stress from factors such as metabolic starvation, DNA damage, toxin accumulation (from cellular metabolism), and the risk of protein misfolding. Preliminary transcriptome data indicates that many mRNA transcripts vary in relative abundance within hepatocytes of D. chrysoscelis during discrete periods of warm acclimation, cold acclimation, freezing, and thawing . Physiological changes that occur in this frog are likely the result of epigenetic regulation—an alteration in gene expression that does not influence DNA sequence. This modification in gene expression can be observed by the subsequent change in relative abundance of mRNA transcripts. This thesis investigates the relative abundance of several mRNA transcripts for (1) methyltransferase genes that mediate some epigenetic regulation by transferring methyl groups (global regulation) and (2) genes that mediate stress responses contributing to freeze tolerance (local regulation). All of the genes selected are orthologous counterparts to those found in humans. We hypothesize that methyltransferases important to the freezing process will be differentially regulated (either up-regulated or down regulated) compared to the warm condition, whereas stress genes that enhance the survivability of the frogs during freezing will be up-regulated and those that are metabolically costly will be down-regulated. These results demonstrate trends in mRNA expression within four biological groups (warm acclimated, cold acclimated, frozen, and freshly thawed) that may be relevant to the freezing process. mRNA was isolated from livers of frogs within the four biological groups at the time they were sacrificed. cDNA was created and relative abundance was identified using RTqPCR techniques. Results were analyzed using ΔΔCt logarithm to calculate fold change. Deeper understanding of physiological processes that either contribute to or are metabolically costly to freeze tolerance may have future applications in human tissue banking and cryopreservation of organs for transplants.

In elderly individuals, LM infections can spread to peripheral organs, causing meningitis with high mortality rate. We have previously shown that short chain fatty acids (SCFAs), fermentation acids found in large quantities in the intestinal lumen, exhibit strong regulatory effects on LM virulence gene regulation. In this study, we investigated the effects of SCFAs on LM virulence using an oral feeding model of LM infection with two different LM strains in young (2 months) as well as old (16-18 months) female BALB/c mice. LM strains used in this study include the serotype 1/2a strain 10403s and the cardiotropic serotype 4b strain 07PF0776. Mice were given SCFAs, individually as well as in two different combinations, in drinking water for four weeks, starved for 24 hours, and orally infected with LM-ladened Nutella. At five days post infection, organs (spleens, liver, heart, gallbladder, ileum, and colon) were harvested and homogenized to enumerate LM colony forming units. We found that for both LM strains, SCFA supplements render the young mice more susceptible to infections but prevent old mice from succumbing to infections. Furthermore, low levels of SCFA mixtures led to a decrease in bacterial burden in the heart of old, but not young, animals infected with the cardiotropic strain 07PF0776. To better understand the different infection outcomes by strains 10403s and 07PF0776, we characterized their LLO production in response to SCFAs in vitro under aerobic or anaerobic conditions. We noted that the presence of low levels of SCFA mixture under anaerobic conditions significantly enhanced LLO production in 10403s but not in 07PF0776. These results indicate that there is a strain-dependent difference in LM response to SCFAs. Moreover, there is an age-dependent effect of exogenous SCFAs on the outcome of animal infections.

any insights generated here can be extrapolated to humans). Previous data from our lab confirms defective proventriculus (dve-a Homeobox gene), an ortholog of SATB homeobox 1 (special AT-rich sequence binding protein 1, in humans), acts as a new member of DV patterning gene hierarchy. In this research, we present that, DV patterning gene (dve), interacts with Dpp signaling. Our results using Gain-of-function (GOF) studies confirms that upregulation of the levels of Dpp signaling by misexpression of decapentaplegic (dpp) and mother against dpp (mad) in dve expression domain results in downregulation of wingless and dramatic eye enlargements. In contrast, downregulation of Dpp signaling by misexpression of brinker ( brk), an antagonist of Dpp signaling in Drosophila, in dve expression domain leads to ectopic induction of wingless in posterior domain of eye and eye suppression or reduced eye phenotypes. In future, we will test if these eye phenotypes are a result of the change of cell fate or due to induction of developmental cell death. To address this, we will test what happens to retinal determination and cell death markers in this background. This study may have a significant bearing on growth, signaling and patterning defects and helps to understand the etiology behind genetic birth defects in the eye.

Modulation of Listeria monocytogenes Carbon Metabolism by Short Chain Fatty Acids College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Diksha Bedi ADVISORS Jeremy M Erb, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Listeria monocytogenes, a bacterial pathogen, is associated with foodborne infections in humans. Listeria encounters short chain fatty acids (SCFAs) during its transit through the intestine but its metabolic responses to SCFAs are not fully understood. To determine how Listeria metabolism is affected by SCFAs, I performed basic microbiology assays, including monitoring optical density, determining acetoin production, and measuring culture pH levels. I also performed preliminary 13C-NMR assays to provide a more in-depth look into carbon metabolism in SCFA-treated Listeria. I found that propionate-supplemented Listeria produced significantly more acetoin compared to no supplemented controls. Because acetoin is a product of central carbon metabolism, my result suggests that Listeria is capable of changing its carbon metabolism in response to propionate. My preliminary 13C-NMR results have not revealed how carbon metabolism is altered by propionate and are under current investigation. Further investigation will provide more knowledge in the metabolic mechanism associated with Listeria responses to SCFAs during intestinal transit.

absence of oxygen affects how pathogens respond to propionate. In this study, we investigated how propionate exposure affects Listeria monocytogenes growth and virulence factor production under aerobic or anaerobic conditions. Under anaerobic conditions, propionate supplementations had no effect on planktonic growth but resulted in decreased adherent growth. In contrast, under aerobic conditions, propionate supplementations resulted in a pH-dependent inhibition of planktonic growth and increased adherent growth. The effects of propionate on planktonic growth are also temperature-sensitive. At room temperature, propionate supplementation resulted in decreased doubling times under aerobic but not anaerobic conditions. To begin to investigate the effects of oxygen on L. monocytogenes response to propionate, we further noted that supernatant from cultures grown with propionate contained an increased amount of acetoin under aerobic conditions and a decreased amount of ethanol under both aerobic and anaerobic conditions. Moreover, L. monocytogenes grown with propionate exhibited an increased proportion of odd number straight chain fatty acids in a manner that was more pronounced under anaerobic conditions. Finally, aerobic suppression of listeriolysin O (LLO) production and anaerobic induction of LLO production were observed in L. monocytogenes grown with propionate. These results clearly demonstrate for the first time that L. monocytogenes exposure to propionate resulted a variety of physiological and pathogenic responses. Moreover, the presence or absence of oxygen plays a critical role in shaping L. monocytogenes responses to propionate that can potentially impact bacterial survival in the environment and subsequent interactions within host cells.

My goal is to develop tools to manipulate either the tumor or the normal neighboring cells and test the effect of tumor growth and progression.

The Effects of Sublethal Ampicillin Exposure on Listeria monocytogenes Virulence College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Marlena Rae Merling ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Antibiotics can be found in sublethal levels environmentally as pollution and within the body when used as medication. Antibiotics induce stress responses and sometimes act as signalling molecules in bacteria. In order to better understand the relationship between antibiotics and bacterial infections, the effects of sublethal antibiotic exposure on the ability of Listeria monocytogenes to infect macrophages was studied. Listeria monocytogenes is an intracellular pathogen of the gastrointestinal tract that is facultatively anaerobic. Two strains of Listeria monocytogenes were tested: a lab strain and a clinical cardiotropic strain. The strains were grown in liquid media overnight aerobically or anaerobically with either no antibiotics or with a 0.05 Îźg/mL concentration of ampicillin, which is the main antibiotic used to treat Listeria infections. Bacteria from the overnight cultures were used to infect RAW264.7 cells (macrophages) at a multiplicity of infection of 10. The number of intracellular colony forming units (CFUs) were measured at 2 and 24 hours post-infection by plating the cellular lysate. Using the number of intracellular CFUs, the percent input was calculated to measure amount of Listeria present inside the macrophages at each timepoint. The results for both strains showed no significant difference in the ability to infect and replicate inside macrophages between Listeria grown with or without ampicillin. Interestingly, the aerobically grown cardiotropic strain had a significantly lower percent input than the lab strain at 2 hours post infection, but there was no significant difference in percent input between the strains at 24 hours post infection. This suggests that although the cardiotropic strain cannot infect macrophages as well as the lab strain, it can either grow better or resist macrophage killing better than the lab strain. Future directions include testing higher levels of antibiotics and exploring the differences in virulence between strains of Listeria monocytogenes.

Goal 3: Good Health and Well-Being STUDENTS Katie Lynn Breitenbach ADVISORS Jana M Bennett, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Listeria monocytogenes is a food borne pathogen that is capable of causing the disease listeriosis typically in the elderly, pregnant women, or immunocompromised people. It has a relatively high death rate in the U.S. compared to other foodborne pathogens--about 1 in 5 cases ends in death. The bacterium is an intracellular pathogen, which means it requires entrance into a host cell to carry out its pathogenic activity, grow, and spread. To do this, it must cross the mucosal barrier of the intestinal lining. Through a series of various protocols, this study primarily investigates how anaerobic conditions and short chain fatty acids such as propionate, to which we know Listeria is regularly exposed in the gut, affect the bacteriumâ&#x20AC;&#x2122;s ability to interact with the mucosal barrier. In addition, this study also contributes an understanding of how the disease should be addressed ethically in the U.S. today.

Understanding the development of antibiotic resistance in Listeria monocytogenes College of Arts and Sciences: Biology Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Andrea Marie Vietti ADVISORS Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Bacterial antibiotic resistance is on an alarming rise worldwide, thus posing an urgent threat to human health. The rise in antibiotic resistance can be attributed to the overuse and misuse of antibiotics in both the healthcare and agricultural industries. In order to address this concern, this research is aimed to identify environmental conditions that may lead to the development of antibiotic resistance in Listeria monocytogenes. Listeria is a foodborne pathogen capable of causing the disease listeriosis especially in immunocompromised populations. Although infected individuals are treated with antibiotics, an alarmingly high mortality rate of 20 percent still persists; thus, it is important to further understand the impact various environmental conditions may have on the development of antibiotic resistance. Various genetic mutants of Listeria were exposed to antibiotics commonly used to treat Listeria infections, and the susceptibility to these antibiotics was observed under environments with and without oxygen.

Axial patterning is the fundamental process of organogenesis, which entails delineation of three distinct axes: Antero-Posterior (AP), Dorso-Ventral (DV) and Proximo-Distal (PD) axes. Any impairment in the axis formation may lead to developmental birth defects in humans and therefore, getting insight of the mechanism of axis determination is crucial for better understanding of organogenesis. In Drosophila eye model, DV patterning is the primary lineage restriction event. A new member of DV patterning gene, defective proventriculus (dve, a Homeobox gene), an ortholog of SATB homeobox 1 (special AT-rich sequence binding protein 1) has been identified which acts downstream of a GATA-1 transcription factor pannier (pnr), and upstream of wingless (wg) in the dorsal gene hierarchy. Unpaired (Upd), a long range secreted ligand for JAK STAT pathway, is known to promote eye development by negatively regulating Wg expression. Here we present that Upd interacts with dve, to regulate the patterning and growth of the developing Drosophila eye. We found that activation of JAK STAT pathway in dve expression domain results in dorsal eye enlargement and downregulation of Wg expression whereas its inactivation in Dve domain results in eye suppression phenotype and upregulating Wg expression. Our data strongly imply that Upd plays a crucial role in defining the functional domain of Dve during DV axis formation of developing eye. We will present the complex interactions between these two highly conserved pathways, viz., JAK-STAT and dorsal eye fate selectors in growth and patterning of the eye.

Roles for cell-cell signaling in the spread of Aβ42-mediated pathology in Drosophila eye model College of Arts and Sciences: Biology Poster - Independent Research

Goal 3: Good Health and Well-Being STUDENTS Prajakta D Deshpande, Ankita Sarkar, Catherine Jean Yeates ADVISORS Madhuri Kango-Singh, Amit Singh LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Alzheimer’s disease (AD) is a debilitating neurodegenerative disorder with no cure and few effective treatments. AD causes profound cognitive deficits and memory impairments. Here we use a Drosophila model of AD to study the interactions between diseased and healthy cells to better understand the spread of the disease through the brain. Accumulation of the peptide amyloid beta into plaques is one of the characteristics of the disease. A 42 amino acid peptide, Aβ42, is a cleavage product of Amyloid Precursor Protein. Aβ42 tends to aggregate and forms oligomers, eventually making up the plaques seen in the disease. Human Aβ42 can be expressed in the developing retinal cells of fruit flies. In this study we use twin-spot MARCM (Mosaic Analysis with a Repressible Cell Marker) with the FLP/FRT system to express Aβ42. This yields animals with GFP-negative WT cells adjacent to GFP-positive Aβ42-expressing cells in a heterozygous background. We found that populations of Aβ42-expressing cells are much larger than the adjacent populations of WT cells. This suggests that cell-cell signaling between the two populations may be either interfering with the proliferation of WT cells or inducing cell death at a later stage in development. Previous research has implicated Aβ42 in the aberrant activation of pathways leading to cell death. Here we present evidence that signaling between Aβ42-expressing cells and adjacent WT cells mediates neurodegeneration.

To test for antibiotic susceptibility in these bacteria, disc diffusion assays were performed by spreading the bacterial isolate on LB agar and placing discs that contain antibiotics Rifampin, Streptomycin, and Penicillin on the agar. After 24 and 48 hours, the diameter of the growth inhibition zone was measured in mm. The bigger the diameter, the more susceptible the bacteria are to the antibiotic. Out of the 17 isolates, only three were susceptible to Penicillin, demonstrating that there was a high level of Penicillin resistance. In contrast, 16 out of 17 isolates show susceptibility to Rifampin. Fewer isolates are susceptible to Streptomycin but the diameter for the zone of inhibition was larger. From these results, it is clear that antibiotic resistant bacteria are indeed present in the grasshopper, potentiating grasshoppers as a vehicle of antibiotic resistance transmission.

Thus, efforts should be made to discover better inhibitors of glioma growth. Ideally such inhibitors will suppress the progression of glioma by (a) inhibiting the underlying molecular pathways activated in glioma, or (b) prevent rapid proliferation of the glia and other cells that encompass the glioma tumor. We have developed a glioma model by co-activating PI3K and Ras/MAPK specifically in the Drosophila CNS glia. The Drosophila glioma cause the larval brain to appear enlarged due to rapid increase in the stem cells and their glial and neural progeny. These tumors cause the larvae to enter a prolonged larval phase, and eventually kill the organism. We are conducting a chemical screen using Tyrosine kinase inhibitors (Selleck Biochem.) in which we feed early third instar (72h old) larvae 10 or 300uM chemicals in DMSO and then see effects on glioma growth, and survival in mature third instar stage (120h old). Using these metrics, here we present data from our screen pertaining to drugs from rows A, B, C, and D of our library. Once we identify potential glioma inhibitors in the primary screens, we will validate them in secondary screens.

We are the co-inventors of two patented novel technologies for the treatment of antibiotic resistant bacteria. Both treatments make use of a novel porphyrin ZnPor (US Patent # 9,364,537) that does not require using traditional photo-activation i.e., it exhibits unique dark toxicity. Current studies have indicated the utility of photodynamic therapy using porphyrins in the treatment of bacterial infections. Photoactivation of porphyrins results in the production of singlet oxygen that damages biomolecules associated with cells and biofilms, e.g., proteins, polysaccharides, and DNA. The effect of a ZnPor on P. aeruginosa PAO1 biofilms and planktonic cells was assessed without photoactivation. Biofilms were visualized using confocal laser scanning microscopy (CLSM) and cell viability determined using the LIVE/ DEAD BacLight viability assay and standard plate count was used for planktonic cell viability. At a concentration of 25µM ZnPor, there was substantial killing of P. aeruginosa PAO1 wild-type biofilms with significant disruption of the biofilm matrix or structure. Biofilms pretreated with ZnPor without photoactivation were substantially more sensitive to tobramycin than untreated biofilms. 4-log10 reduction in viable cells of wild-type PAO1 planktonic cells was observed at a concentration of 12.5 µM. Our results suggest that ZnPor permeates into the PAO1 cells and makes the cell membrane permeable/compromised. Also, the interaction study of ZnPor with the PAO1 DNA shows that the porphyrin interacts strongly with the DNA and aggregates around the helix of the DNA.

Abnormal function of calcium-handling machinery has been implicated in the pathophysiology of ADHD in humans and in animal models. Intracellular calcium homeostasis in the brain is critical for cell function and survival. In the nervous system, impaired calcium homeostasis may lead to hyperactivity and learning and memory deficits, key symptoms of ADHD. Exciting preliminary data from our group support that a protein, which plays a major role in regulation of calcium homeostasis in the heart, is also expressed in a specific region of the brain that is implicated in the neurobiology of ADHD. Moreover, we have found that its genetic ablation in mice (i.e., knockout, KO) results in the manifestation of a hyperactive ADHD-relevant behavioral phenotype. In the present study, WT and KO mice were pharmacologically challenged with amphetamine and atomoxetine, two first-line drugs used for the treatment of ADHD in humans, to assess whether they rescue the ADHD-like phenotype caused by ablation of this gene. Additionally, a preliminary neurochemical analysis of striatal and prefrontocortical tissue punches by high-performance liquid chromatography (HPLC) was performed to determine baseline dopamine levels in KO and WT mice. Overall, the results of the proposed studies have shed light on the complex functions of this novel calcium-handling player in the brain suggesting it is involved in the regulation of locomotor behavior.

The Role of Sensors and Effectors in Protein-Protein Interactions College of Arts and Sciences: Biology

Oral Presentation - Course Project, 201880 BIO 421 P1 STUDENTS Jenea Imani Adams ADDITIONAL AUTHORS Ivet Bahar, Luca Ponzoni, Hongchun Li, Burak Kaynak ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union 311, 11:00-11:20 Protein-protein interactions are a fundamental molecular event which underlies many key biological processes—such as muscle excitationcontraction coupling, cardiac activity, and every-day function of the central nervous system. This computational experiment aims to analyze the relationship between “sensors” and “effectors”5 on protein surfaces as identified by Perturbation Response Scanning1 computed from Elastic Network Models6, and their connectedness to interfacial residues/allosteric binding sites. The authors hypothesize that Proteins preferentially interact with their substrates at their sensor residues (H1) and that their sensor and/or effector residues could be allosteric binding sites (H2). Preliminary results, obtained utilizing the functionality of the ProDy3 Python package, suggest that sensors are most likely to be found on a protein-protein interface than effectors.

Klocke, Katelyn Nicole Shea, Isaiah Taylor, Connor F Thelen ADVISORS Pothitos Pitychoutis LOCATION, TIME Kennedy Union 312, 11:20-11:40 A diet high in saturated fats has been known to induce metabolic stress that over time may lead to insulin resistance and eventually symptoms of type 2 diabetes. The development of these metabolic diseases is often comorbid with symptoms of depression and anxiety. Previously conducted studies have found that male rodents subjected to a high fat diet develop classic symptoms of anxiety and depression (e.g., behavioral despair, reduction in exploratory activity)which can be effectively treated with a single subanesthetic dose of the non-competitive N-methyl-D-aspartate receptor antagonist ketamine. Despite this, little is known about how a high fat diet regimen may affect the behavioral profile of female rodents, and if ketamine may reverse high fat diet-induced behavioral deficits. This study sought to assess basal behavioral sex differences in C57BL/6J mice exposed to a high fat diet regimen, and to assess whether ketamine may rescue depressive and/or anxietylike behaviors in a sex-dependent manner. Preliminary behavioral analysis in this project was conducted in the context of the experiential learning research component of the Fall 2018 Neurobiology Laboratory (BIO415L) class.

Goal 15: Life On Land Goal 11: Sustainable Cities and Communities STUDENTS Taylor Marie Sparbanie ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union 311, 11:20-11:40 Maintaining and fostering biodiversity is a critical component of natural areas management and conservation because of its known links to ecosystem function and stability. Identifying and documenting species through a floristic inventory is an important strategy for detecting the presence of rare or unique species, as well as invasive species that pose a threat to biodiversity. Bill Yeck Park is a 194-acre nature park maintained by Centerville-Washington Park District and is largely surrounded by residential areas. As urban green spaces like Bill Yeck Park become more prevalent and they play an increasingly important role for the provision of ecosystem services in a postmodern, industrialized, and developed world, documenting the species composition and ecological function of these nature parks become critically important for informing management. The goal of this project is to generate list of vascular plant species for Bill Yeck Park, a large park within the Centerville-Washington Township park district. Through this work, a biodiversity inventory will be developed, critical areas for conservation will be identified, and the removal of invasive species will be strategized. Floristic surveys for this project began in March of 2017. 245 species have been identified and documented across a variety of habitats, including meadows, riparian corridors, and upland forest.

The goal of the research is to isolate bacteria that displays anti-microbial effects on known pathogens. This research could potentially be used to help create new antibiotics to fight against human pathogens. A dirt sample was collected from the side of my house in the UD south student neighborhood. Colonies of bacteria formed on TH and TSA plates. Ten colonies were chosen from each of these types of agar plates. The colonies were plated on dishes streaked with the known pathogens, Pseudomonas aeruginosa and Enterococcus faecium, then later Klebsiella pneumoniae, and Staphylococcus aureus. The colonies that formed zones of inhibition were isolated and further testing was done to determine the species and characteristics of the bacteria. Some of these tests included a gram stain, catalase test, and various other biochemical tests to determine characteristics of the antibiotic producing bacteria. Later this semester, I will perform a chemical extraction for the metabolites of the chosen bacteria as well as observe the interaction between the extract and eukaryotic cells.

Isolating Antibiotic Producing Bacteria from Soil College of Arts and Sciences: Biology Poster - Course Project, 201910 BIO 411L 05

STUDENTS Megan Ashley Marasco ADVISORS Erica Marie Rinehart, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 There are many issues within healthcare, with one of the most concerning being antibiotic resistance. Healthcare providers’ over-prescribing of antibiotics artificially selects for antibiotic resistant populations. Over time, bacteria that are selected for have the ability to become resistant to one or many of the antibiotics that are currently used in healthcare. These types of pathogens that can survive antibiotics are called “super bugs” and those are the type that healthcare providers worry about. These “super bugs” are the type of pathogens that are causing the issues, since there has been no new antibiotic class discovered in the last decade or they are still in the FDA approval process. Thus, the goal of my project is to explore the soil for antibiotic producing bacteria. The soil is home to a diverse set of microbes that are constantly competing for nutrients. Most of today’s antibiotics were discovered in the soil. Some bacteria develop the ability to create antibiotics in order to kill their competition. This characteristic is not only beneficial to their survival, but also to us. After soil isolation, we ran several tests for identification, production of antibiotic compounds, and extraction of the compound. The compound was then tested for effectiveness against known pathogens and safety in eukaryotic cells. This process allows for quicker antibiotic discovery in a teaching lab. With the many people working to discover new antibiotic compounds a major issue in the healthcare field can be corrected before all antibiotics become obsolete when treating bacterial infections.

We collected macroinvertebrate samples using sweep net, kick net, and artificial substrate sampling methods. Fish were sampled using electroshocking techniques. Macroinvertebrate samples were preserved in ethanol, sorted, identified, and counted in the lab. Fish were identified in the field and released. Data was also collected on levels of fecal coliform bacteria in the river near the kayak chute to assess recreational safety of kayakers using the feature.

The standard of care is surgery followed by radio- and chemo/ immuno-therapy, or combinations thereof, however, all patients with glioma ultimately die. Thus, there is a need to test if recently approved drugs can inhibit the growth and progression of this tumor. We have developed a Drosophila glioma model based on the two genetic/ oncogenic pathways known to be most frequently activated in patients viz., the Ras/MAPK pathway and the PI3K pathway. Inhibitors of these two pathways do not help to limit the progression of glioma. Therefore, it is thought that other oncogenic pathways induce glioma growth and progression. We designed a chemical screen involving drugs targeting Tyrosine kinases (Selleck Biochem Chemical library) – key enzymes that are activated by oncogenic pathways. The chemical screen involves feeding glioma containing larvae 10uM and 300uM drugs from the library at early third instar stage, then allow these larvae to grow and mature to the third instar stage (120h of development), and then dissect the brain to study effects on glioma growth and track survival on days 5-7 when other glioma positive larvae die. Here, we present our progress from this screen focusing on the chemicals of rows E, F, G, and H of our inventory.

year post-fertilization in 2018. Based on results from 2017, we conducted feeding trials, that manipulated the ratio of Ca:Na (by 10%, 25%, and 40%) in food, on an invasive ant, Nylanderia fulva in 2018. In 2017, N. fulva was the dominant litter arthropod across all treatments, and their abundance was limited by Ca, but tends to be suppressed by Na. In 2018, however, these effects disappeared as soil cations were likely leached from the soil, and abundance of N. fulva dropped 98%, likely due to Hurricane Harvey. Preliminary lab results show that manipulating the Ca:Na ratio in the food of N. fulva affects colony fitness, indicating that Na can reach toxic levels, suppressing colony size, while Ca ameliorates these toxic effects. These results indicate that changes in micronutrient availability may facilitate the success of an invasive species, and gives insight as to how human activities are altering coastal ecosystems.

Water quality and captivity both affect the birth rate of the stingray Rhinoptera bonasus College of Arts and Sciences: Biology Poster - Independent Research Goal 14: Life Below Water STUDENTS Rachel Elizabeth Brewer ADVISORS Patrick K Williams LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Little research has been done on stingrays in captivity and in the wild, which is an important topic that I felt needed further investigation. Stingrays are marine and freshwater Chondrichthyan fishes that are commonly displayed in aquariums and zoos worldwide. While there is significant scientific knowledge of rays there is much remaining to know about these fascinating organisms. My internship at the St. Louis Zoo, allowed me to dive into the world of stingrays. Zoo’s all over the world create their exhibits to mimic what habitats would be like for the animals in the wild. At the St. Louis Zoo, Caribbean Cove is home to Cownose and Southern stingrays. These gentle creatures have a flat body, long pointed, fins, and a long whip-like tail. The Cownose and Southern stingrays breed during summer to early fall in shallow waters out in nature. In captivity, these rays breed throughout the year. The goal of this project was to understand how captivity may influence stingray births by observing water quality and environmental control. This study evaluated the differences in the St Louis Zoo’s pool temperature in relation to the number of births of Cownose stingrays. By evaluating the time of year that the ray pups were born in comparison to water temperature, I found that in captivity more stingrays were born in the month of May. I then compared this to other published research to see if there was a correlation between the breeding period in captivity versus the wild. More importantly, I will include all the contributing factors that may influence the Cownose and Southern stingrays breeding patterns.

COLLEGE OF ARTS & SCIENCES

STUDENTS Anna Kathleen Benton ADVISORS Douglas C Hansen, Karolyn M Hansen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The eastern oyster, Crassostrea virginica, forms shell through the process of layer by layer construction. There are two components of shell: the hard layer made of calcium carbonate and the soft layer made of organic matrix. This project focuses on a specific class of proteins found in the organic layer that contain a unique amino acid, L-3,4-dihydroxyphenylalanine (L-DOPA). This class of proteins is of interest because of the crosslinking capabilities of L-DOPA. L-DOPA can adhesively bind to calcium carbonate and cohesively bind to other amino acids as confirmed by the study of L-DOPA-containing Mytilus edulis foot proteins. L-DOPA can be used as a biomarker for these proteins and can be assayed or tracked using the ARNOW assay, a catechol stain, on adductor muscle tissue. Market quality oysters were shucked, and tissue samples were collected from the adductor muscle. Proteins were extracted by homogenizing the tissue, soaking the tissue in 0.7% perchloric acid solution, precipitating proteins with cold acetone, and resuspension in 5% acetic acid. Once the initial extraction was complete, the protein solution was concentrated using ultrafiltration under inert gas to prepare the solution to be run on a high-pressure liquid chromatography (HPLC). After HPLC separation, proteins are further characterized using acid-urea polyacrylamide gel electrophoresis. The AAA-Direct Amino Acid Analysis System was then used to determine the percentage concentrations of the amino acids present in the purified proteins. Purified protein with high L-DOPA content will be sequenced using a commercial vendor. Once the sequence is obtained, proteins will be modeled using ChemDraw, Chem3D, and Gaussian-9 software. Modeling using published sequences of putative shell formation proteins has revealed the occurrence of specific folding domains that may play a role in adhesive and cohesive binding of those proteins. We anticipate finding similar tertiary structure in proteins isolated and characterized from Crassostrea virginica.

An Incomplete Guide to all Plants, Animals, and Insects in the Environmental Research Area at Old River Park College of Arts and Sciences: Biology Poster - Course Project, 201880 BIO 479L P1 Goal 15: Life On Land STUDENTS Mary Catherine Lloyd, Celia Montemurri, Caroline Marie Shepherd, Taylor Marie Sparbanie ADVISORS Ryan W McEwan, Alyssa Ashley Outhwaite LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 An important first step in managing an ecosystem is discovering the biodiversity already present, to have the opportunity to bolster it, protect it, and manage for it. One way to document biodiversity is to perform a BioBlitz. A BioBlitz is an event where a group of people, usually including volunteers, aid a research group in identifying all species of living things in a certain area. During the one semester, or approximately four months, of this project the lab team focused on identifying certain categories of species. The Environmental Research Area is approximately 60-70 acres and surrounded by a moat-shaped lake. The research team focused on birds, plants, insects, mammals, and trees. Other categories are included in a master plan to be completed in the future. 104 species were identified in total within the set taxa. Many factors, such as time and resource constraints, contributed to the lower numbers of identification for other major groups of organisms. With further surveying to compile a more complete list of species, this list can serve as a useful tool in making management decisions to best protect the natural inhabitants of Old River Park, the Great Miami River, and Dayton.

Alien treeâ&#x20AC;&#x2122;s sugary SOS exploited by thieving tramp ant: unidirectional benefit in a tritrophic mĂŠlange College of Arts and Sciences: Biology Poster - Graduate Research Goal 15: Life On Land STUDENTS Emily Elizabeth Jones, Natalie Christina Martin ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Triadica sebifera (Euphorbiaceae), a centuries old invader of southern ecosystems, was virtually free from natural enemies until the specific, hypermetamorphic moth Caloptilia triadicae (Lepidoptera: Gracillariidae) appeared in 2004. Simultaneously, populations of the destructive tawny crazy ant, Nylanderia fulva (Hymenoptera: Formicidae), spread cospatially across the southeast. To examine potential interactions among these species, we sought answers to these questions: 1) does Caloptilia induce extrafloral nectar production in Triadica; 2) does N. fulva consume nectar, larvae, or both; and 3) does N. fulva provide indirect defense to the tree, or to its attacker? To understand these interactions, and their implications for southern ecosystems, we conducted a series of lab, greenhouse, and field experiments in coastal Texas.In response to herbivory by Caloptilia, potted Triadica saplings strongly induced extrafloral nectar production. Percent leaf damage explained 57% of the variation in cumulative nectar volume (p<.0001), and nectar volume on saplings with >20% of leaves damaged was significantly greater than on controls (p=0.0005). Nylanderia fulva exploited available nectar resources without attacking Caloptilia larvae. On potted saplings, nectar volume was significantly lower when ants were present (p=0.008), while no differences were observed in Caloptilia

survivorship (p=0.56). Likewise, no differences in Caloptilia abundance or parasitism rates were observed when ants were excluded from naturally recruited Triadica saplings (p=0.97;p=0.8). Large Caloptilia infestations reduced trunk elongation in Triadica saplings (R2=0.32, p<.0001), but had no effect on leaf production, biomass, or survivorship. Because Triadica saplings supplied N. fulva workers a carbohydrate resource while sustaining heavy damage, and because neither Triadica nor Caloptilia benefited from worker foraging, N. fulva was the only beneficiary in this alien, tritrophic interaction.

Patience, Young Grasshopper: Identifying the fungal composition of the grasshopper microbiome College of Arts and Sciences: Biology Poster - Honors Thesis Goal 15: Life On Land STUDENTS Melani Muratore, Staci N Seitz ADVISORS Ying-Ju Chen, Chelse M Prather, Yvonne Y Sun LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Microbes inhabit many corners of the Earth, including the intestines of all animals. These intestinal microbes, collectively called the “gut microbiome,” provide numerous nutritional and regulatory functions for the animals they live in and thus play an important role in animal health. The fungal communities in insects, specifically, play a diverse, but important role in insect physiology, as well as insect control. The overall goal of this project is to identify the fungal communities in grasshoppers to enrich our knowledge in insect fungal microbiome. Questions that we wanted to answer were: “what is the composition of the fungal communities in the microbiome of grasshoppers?” and “what drives the composition of the fungal communities in the microbiome of grasshoppers?” In this study, we investigated the composition of the fungal community inside grasshoppers. The grasshoppers were collected in the summer of 2017 from a Texas prairie as part of a multifactorial micronutrient experiment. DNA was extracted from the grasshopper gut and submitted for sequencing by Zymo Research. After analyzing the sequencing results, we identified two fungal phyla that were present in all samples: Ascomycota and Basidiomycota. Within Ascomycota, the class Dothideomycetes is most prevalent. Within Basidiomycota, the classes Tremellomycetes and Ustilaginomycetes are most prevalent. Dothideomycetes are typically found as saprobes, or decomposers, that break down dead leaf matter. They are also commonly found on living plants, acting as pathogens or endophytes. Tremellomycetes are a type of pathogenic fungus that acts as a parasite toward insects and plants. Ustilaginomycetes, known as “smut fungi,” act as a parasite toward vascular plants. All of these classes of fungi are directly involved with plant matter. Further statistical investigation will be done to determine the drivers of the diversity of these fungal communities and their significance.

Poster - Independent Research Goal 15: Life On Land STUDENTS Emily Elizabeth Jones, Troy Harry Lampenfeld, Olivia Margaret Pettigrew ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Antibiotics are extremely prevalent in modern medicine and are used in treatment of a multitude of bacterial infections and diseases. As such, humans are increasing the abundance of antibiotics in many natural systems, especially those close to range-land systems where cattle are often prophylactically treated with antibiotics. Increases in antibiotics could be detrimental to organisms, such as herbivorous insects that need to maintain their microbiota to help break down their food. A small choice experiment was conducted to determine the effect of the antibiotic tetracycline on the dietary habits of Chortophaga viridifacsiata (Orthoptera: Acrididae), a species of grasshopper native to Ohio. The results of this experiment did not yield significant evidence that C. viridifacsiata show dietary discrimination between grasses treated with tetracycline and grasses grown under normal conditions. However, there was a trend towards reduced feeding on plants grown with antibiotics, which could be important given the small sample sizes of this study. Future experiments will include a wider array of antibiotic treatments as well as multiple species of grasshoppers. If the antibiotic enrichment of these ecosystems is causing changes in herbivory patterns among arthropod communities, it could be impacting arthropod and plant community structures depending on which species of plants are taking up these antibiotics.

Insectile Neurochemistry: Developing a novel HPLC-based method to assess neurotransmitters in the grasshopper brain College of Arts and Sciences: Biology Poster - Independent Research Goal 15: Life On Land STUDENTS Benjamin Klocke ADVISORS Pothitos Pitychoutis, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Grasshoppers (Order Orthoptera) are critical members of grassland ecosystems; as herbivores they serve an important role in many ecosystem services. They can also cause very costly destruction of crops and are seen as pests in agriculture. Therefore, understanding grasshopper behavior is critical to fully understand their impact on the environment. Many chemical pesticides and fertilizers used in agriculture affect the balance of micronutrients such as sodium (Na) and calcium (Ca). Similar micronutrient shifts have recently been correlated to an alteration in grasshopper activity. It is currently hypothesized that changes in neurotransmitter systems in the grasshopper CNS underly this response. Therefore, understanding the neurochemical mechanisms underlying these observed behavioral changes is necessary to fully understand the impact of chemicals used in agriculture. However, only a few studies have assessed neurotransmitters have not been quantitatively assessed in insects. Thus, the purpose of this project was to develop a novel HPLC-based method to assess neurotransmitters in the grasshopper brain. This method will be used in collaborative projects by the Prather and the Pitychoutis labs here at the UD to conduct studies exploring grasshopper neurotransmission dynamics following micronutrient shifts in the ecosystem.

Since the prairie will be growing by Fall 2019, further observation will take place to test the central question in this study. Continuing this study could help many communities plan for thriving pollinator communities as they begin to install ground solar panels.

Insect communities as indicators of restoration in an urban prairie network College of Arts and Sciences: Biology Poster - Graduate Research Goal 15: Life On Land Goal 13: Climate Action STUDENTS Amanda N Finke, Beth Margaret Fuchs ADVISORS Kathleen A Kargl, Chelse M Prather LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The increasing negative effects of human impact on Earth has led to the urgent need for large-scale ecological restoration. One ecosystem of particular interest is tallgrass prairie, which is one of North Americaâ&#x20AC;&#x2122;s most endangered ecosystems. However, restored and constructed prairies often do not support the same biodiversity and ecosystem services as remnant prairies. Most restoration projects only focus on reinstating vegetation, assuming other trophic levels will colonize on their own. One of these taxonomic groups are arthropods, which make up a majority of the biodiversity in prairies. We sought to determine if there is a difference in the arthropod communities of constructed and remnant prairies. It was hypothesized that arthropod communities would be different, and older constructions would more closely resemble remnants. Indicator species could be identified, which possess certain functional traits (morphological or life history) that allow them to colonize these sites. Sweepnet samples (100 sweeps per site) were taken at 5 constructed prairies and 5 remnant prairies in 2017, and 7 constructed prairies and 6 remnant prairies in 2018. All arthropods were sorted to order, and some orders to morphospecies. We saw that in 2017, Coleoptera (beetle) abundances were higher in remnants compared to constructions (p=0.04). In particular, Phalacridae (shining flower beetles) could be possible indicator species for restoration in prairies. Preliminary data from 2018 shows that the number of Phalacridae increases with the age of the constructed site (RÂ˛=0.47). These results suggest that insect communities are different in the two prairie types and certain species of arthropods are not being restored in one or two years, but rather over long periods of time as late-successional species are able to colonize. These results could have large implications on how tallgrass prairies are restored and managed, and how these ecosystems should be assessed for restoration.

STUDENTS Sara Marie Brunner, Erin Nicole Ferrell, Drew Daniel Gojsovich, Alex Everitte Newman-Caro ADVISORS Ryan W McEwan LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 This study was designed to be a vital stepping-stone in the long-term ecological restoration of Old River Park, located in Dayton, Ohio. For over fifty years, this park served the public and inevitably became a significant part of the Dayton community. Nestled within the park is a deserted Putt Putt course that has been consumed by invasive plants such as Callery pear (Pyrus calleryana) and honeysuckle (Lonicera maackii). Due to the lack of natural predators, these plants actively inhibit the growth of other native species by outcompeting them for vital resources such as sunlight and water. This has ultimately led to a detrimental decrease in native plant biodiversity. The objective of this project was to restore the course by first clearing and controlling the invasive plants. A trial-and-error process was utilized to determine individualized methods of removal. Spaded shovels were best-suited for removing Callery pear, while clippers were best-suited for removing honeysuckle. To re-enforce the natural competition within the area, the team visited different sites within Old River Park and collected native prairie plant seeds. Species included pokeweed (Phytolacca americana), white snakeroot (Ageratina altissima), goldenrod (Solidago), and wingstem (Verbesina alternifolia). The team collected no more than twenty percent of seeds from each population to ensure phenotypic diversity and genotypic variability. These seeds were then dispersed within the cleared areas of the course. Ultimately, the group was able to remove invasive species from fourteen of the eighteen Putt Putt holes. As a continuing project, further results are pending based on the re-growth of invasives during the spring, summer, and fall of 2019. The team also worked with other students and Dayton community professionals to produce a long-term vision and restoration goal for the site. Native plants will be seeded at each hole of the course based on sunlight and nutrient availability, conclusively producing a “native prairie garden walk” for public education and enjoyment. This research is important because it will allow University of Dayton students to understand the importance of native ecology and the substantial impact that humans can have on natural environments.

A single dose of the novel antidepressant drug ketamine has been shown to rapidly induce antidepressant-like effects in both depressed patients and in preclinical rodent models of depression. It is theorized that ketamine’s therapeutic effects are mediated by a burst of glutamate, an excitatory amino acid, in the medial prefrontal cortex (mPFC) inducing synaptogenesis or the formation of synapses in the PFC and the hippocampus (HIPP). Recently our group found that ketamine induced sex-specific synaptogenic effects in both the mPFC and HIPP and that these effects were more pronounced in the female HIPP. In order to further understand ketamine’s antidepressant effects in female mice, we implemented a cutting-edge in vivo brain microdialysis technique to assess putative sex differences in ketamine-induced glutamate release in the HIPP of male and female mice.

STUDENTS Celeste Claire Bergman ADVISORS Karolyn M Hansen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 High density growth of bacteria tend to form biofilms by excreting an extracellular matrix. This matrix is composed of adhesive components such as polysaccharides. The polysaccharides serve as cell-to-cell attachments and a selective filter for which outside material must pass. By forming the biofilm, the bacteria create a defense mechanism against antibiotic attacks and other abrasive environmental factors. Pseudomonas aeruginosa is a biofilm forming bacteria with known antibiotic resistance. Four strains were tested, ΔwspF, ΔwspF Δpel, ΔwspF Δpsl, and ΔwspF Δpel Δpsl. Each strain produced differing amounts of the polysaccharides PEL and PSL. The antibiotics gentamicin and ciprofloxacin were used to test antibiotic tolerance of the differing polysaccharides. The results showed that PSL provided antibiotic tolerance against gentamicin but was susceptible to ciprofloxacin. PEL provided antibiotic tolerance to ciprofloxacin but was susceptible to gentamicin.

STUDENTS Bethany R Davies ADVISORS Garry S Crosson LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Biochar is a made through a simple combustion method from any biomass. This research utilized biochar from 3 different biomass sources, as well as a green hydrothermal synthesis, to produce fluorescent carbon-based particles. Characterization of these particles were carried out using Infra-Red, Ultraviolet-Visible, Fluorescence, and Nuclear Magnetic Resonance spectroscopy. These particles are composed of a conjugated carbon lattice with nitrogen and multiple carbon-oxygen functional groups. The use of an economical and green synthesis that allows for the production of these oxidized particles with no waste or by-product, makes this compelling as a research focus. All 3 biocharbased carbon particles exhibit similar strong fluorescent behavior when excited by light in the ultra-violet to near visible range, with light emission occurring in the visible region over a range of approximately 300nm with an emission maximum in the 430-450nm region. The physical and fluorescence characteristics of these particles makes them an ideal candidate for future research into a safe, green, costeffective biosensor.

Antibiotics are not being discovered at a fast enough rate to fight this resistance, leaving many bacterial infections left unable to be treated with the current antibiotics. The efflux of drugs out of cells is one of the mechanisms contributing to this resistance. Transporter proteins called efflux pumps, located in the membranes of bacterial cells, are responsible for this antibiotic exporting activity. In drug resistant bacterial cells, efflux pumps can expel antibiotics out of the cell, making it difficult for the bacteria to receive the intended dose of the drugs. I have investigated the bacterial efflux pumps and their role in conferring multidrug resistance. I sought to identify new efflux pump inhibitors through the screening of extracts made from edible plants and through the development of synthetic nucleic acid aptamers that bind to the efflux pumps and block their activity.

LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Multidrug resistant antibacterial strains are a dangerous problem in modern medicine. One way that bacterial strains can become resistant to common antibiotics is by overexpressing efflux pumps, which are transporters in the cells’ membranes that pump antibiotics out of the cell. The goal is to find inhibitors of bacterial efflux pumps that might reverse the multidrug resistance characteristic. The potential for solving this problem might be found in mother nature. When cells of two different strains are grown together, they must compete with each other for nutrients. This competition can lead to the production of compounds that are toxic to the competing strain. One such compound may be a compound that inhibits the efflux of antibiotics from the cell. To address the multidrug resistance problem, microbes that are known producers of antibiotics will be analyzed and it will be determined if they can produce efflux pump inhibitors that might be therapeutically valuable for us. Preliminary results indicate that two strains, S. griseus and P. polymyxa, might indeed produce an efflux pump inhibitor when they are grown together.

Goal 3: Good Health and Well-Being Goal 12: Responsible Consumption and Production STUDENTS Emily Marie Jones ADVISORS Matthew E Lopper LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Bacteria have steadily developed defenses against antibiotics since the world’s first fleet of antibacterial drugs was introduced. One strategy that bacteria can use to become multi-drug resistant involves the overexpression of large, membrane-embedded efflux pumps, such as the AcrAB-TolC pump found in Escherichia coli (E. coli) and other Gram-negative bacteria. This large efflux pump gives the bacterium the capability of transporting a wide variety of compounds out of the cell, including antibiotics that we use to combat bacterial infections. The overexpression of these bacterial efflux pumps renders our antibiotics ineffective. I have determined that Yerba Mate extract causes accumulation of a fluorescent dye in live bacterial cells and might, therefore, also cause accumulation of clinically relevant antibiotics. I will test the Yerba Mate extract for efflux pump inhibition in the presence of antibiotics and fractionate the crude extract to identify the active compounds that could be inhibiting the efflux pump. This research could open up a new avenue in the treatment of multi-drug resistant bacterial infections.

The purpose of this research project was to develop photomolecular systems that contain photoresponsive properties. Light provides a convenient and sustainable source of “green” energy for manipulating and powering nano materials and biomaterials. The primary molecules focused on in this experiment were two azobenzene derivatives: azobenzene 4,4’-dicarboxylic acid (ADA) and 4-dimethylaminoazobenzene4’-carboxylic acid (M0423). Some azobenzene chromophores undergo cis-trans isomerization when irradiated with UV and visible light. Of the derivatives chosen, only ADA showed photoisomerization capability in its non-aggregated form.A series of dilutions and titrations were performed in order to induce and observe the formation of homo-aggregates of ADA and M0423, and hetero-aggregates containing both molecules. Aggregate formation was monitored using both UV-Vis absorption and circular dichroism spectroscopy. The experiment showed that both ADA and M0423 form aggregates in acidic conditions. Moreover, both ADA and M0423 are achiral but their 1:2 aggregate showed a quite intense CD signal indicating the formation of a chiral assembly despite the absence of any chiral template. The azobenzene-based systems were irradiated with UV and visible light in order to investigate their photodynamic properties. Irradiation experiments showed that the homo-aggregate of ADA is not able to photo-switch while the hetero-aggregate shows some photo-switching capabilities. Future studies will involve the analysis of additional derivatives and an array of hetero-aggregate to better understand their structure and its correlation with photo-isomerization.

An Investigation Correlating Bioluminescence and Metal Reduction Utilizing Shewanella woodyi College of Arts and Sciences: Chemistry Poster - Graduate Research

STUDENTS Allison L Theberge ADVISORS Justin C Biffinger LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The internal transfer of electrons through proteins from high to low electrochemical potentials is a fundamental aspect of life. Some microbes possess the unique ability to transfer internally derived electrons to external insoluble electron acceptors such as electrodes, redox proteins, and other cells in a process known as extracellular electron transfer (EET). Currently, this microbial process is applied in creation of microbial electrochemical systems (MESs). These systems are used in renewable energy and wastewater treatment research and applications. Shewanella woodyi is a cold tolerant, marine microbe that is an understudied candidate for its metal reduction capabilities, although it is closely related to other well-characterized strains in the Shewanella genus. Additionally, S. woodyi has bioluminescent properties and previous research indicated a relationship between bioluminescent intensity and EET existed. The bioluminescence enzyme luciferase relies on reduced flavins to generate light, therefore changes in flavin redox state can have an impact on bioluminescence. Throughout this research, the general growth of S.woodyi under a variety of conditions was characterized. Additionally, the relationship between EET and bioluminescence was confirmed utilizing the soluble electron acceptors of cobalt(II) and nitrate as the substrate for EET. Through high throughput luminescence assays and open circuit potential experiments, it was determined that increasing concentrations of the electron acceptors resulted in decreased bioluminescence output from the cells. Cell viability staining concluded that the increased concentrations of acceptors were not decreasing cell density and thus luminescence output, indicating a valid relationship between EET and bioluminescence.

Using Food Products to Combat Antibiotic Resistance College of Arts and Sciences: Chemistry Poster - Independent Research

STUDENTS Madie O'Brien Clements ADVISORS Matthew E Lopper LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Antibiotic resistance is a rising epidemic in modern-day healthcare. Numerous strains of bacteria have developed resistance to antibiotics, resulting in thousands of deaths worldwide. There are two types of resistance: specific drug resistance and multidrug resistance. Multidrug resistance can be caused by a tripartite protein complex known as an efflux pump that penetrates the inner and outer membranes of the bacterial cell and allows the cell to eliminate waste to the cell’s extracellular environment. In E. coli, one of the major efflux pumps is known as AcrAB-TolC. The goal of this research project is to inactivate the AcrAB-TolC pump via organic compounds extracted from plants. I hypothesize that these natural, organic compounds will block the activity of this pump and prevent antibiotic resistance. To test this hypothesis, I extracted organic compounds from food products and tested them for efflux pump inhibitory activity using a fluorescence-based efflux assay. The results of these experiments demonstrate that an extract of the herb, dill, inhibits the efflux function of the AcrAB-TolC pump in E. coli.

STUDENTS Jacob L Buechele, Kaity Rose McKenna ADVISORS Judit K Beagle LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The need for environmentally safe practices has skyrocketed within the past few years, as soil and water are subject to transition metal accumulation. One way to deal with these contaminations is by use of peraza-crown macrocycles as ligands to remove these metals. Our project focuses on a unique synthesis of the peraza-crown macrocycle that avoids the common use of a metal skeleton. Through the use of the quinoxaline subunit, we are able to greatly increase the binding properties of the peraza-crown macrocycle and the rigidity of the overall molecule.

As greenhouse gas emissions contribute to global warming and an increase in CO2 concentration in the earth’s atmosphere, the scientific community is under pressure not just to examine new technologies to reduce emissions, but also to consider the effect that increased CO2 concentration has on our terrestrial and marine ecosystems. In marine ecosystems, atmospheric CO2 dissolves and reacts with water to form carbonic acid. This diprotic acid then dissociates, contributing to a lowered pH of ocean water and affecting all levels of marine life. Fortunately, nature already has carbonate reduction mechanisms in place that can reduce the harmful effects of ocean acidification. Being able to identify individual bacteria in biological carbonate-fixing consortia can lead to adaptive systems engineered around biofilms. In this study, environmental samples taken from defined sites the dark marine biosphere (ocean depth of 2100-2300 meters) in the Gulf of Mexico were grown in a number of selective medias with defined carbonate contents. Bacterial samples were then analyzed using ion chromatography to measure carbonate consumption as a function of time. The data suggests that by selectively pressuring environmental consortia from the dark marine biosphere toward the purpose of fixing carbon, mechanisms and pathways can be generated to control the level of CO2 in the marine environment.

Investigation of the Cycloaddition Reactions of Some New Azophosphonates and Azobis (phosphonates): A New Manifestation of the Staudinger Synthesis College of Arts and Sciences: Chemistry Poster - Independent Research

STUDENTS Joshua Killian ADVISORS Vladimir A Benin LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Newly synthesized azo-compounds, with one or two pendant phosphonate groups, have recently been shown to react easily with conjugated dienes, such as 2,3-dimethylbutadiene or cyclopentadiene. In both cases, the ensuing [4+2] cycloaddition reactions have led to the preparation, isolation, and full characterization of a series of products. However, there is no clear evidence in chemical literature on [2+2] cycloaddition reactions with an azo-component. These [2+2] reactions are rare in principle, and have been typically conducted with an alkene and a ketene component. This study investigated the question as to whether azo-compounds can participate in such reactions, in place of the alkene component. Investigation focused on diphenylketene, which was reacted with several azobis(phosphonates) or azophosphonates, at ambient temperature. The 1H-, 13C- and 31P-NMR spectroscopic results confirmed that a ring structure was formed, but the data suggested that instead of a [2+2] cycloaddition, resulting in a four-membered ring, a six-membered ring formed, the product of a formal [2+2+2] cycloaddition. The Staudinger synthesis, used for the preparation of β-lactam rings, provides a possible explanation for the mechanism of formation of the six-membered ring.

Tracking disparate colony morphological trends with Thermus scotoductus College of Arts and Sciences: Chemistry Oral Presentation - Honors Thesis

STUDENTS Matt Patrick Leverick ADVISORS Justin C Biffinger LOCATION, TIME Kennedy Union 331, 3:20-3:40 In this project, we sought to observe trends in colony morphology (shape and size) changes using the thermophile Thermus scotoductus on nutrient rich agar plates at 60°C. A general planktonic growth curve was also created to help characterize the activity of this bacterium. When plating most mesophilic bacteria, the colony shape, size, and color tends to be uniform when a single strain is present. When plating defined cell densities of T. scotoductus, however, the colonies were not of uniform size and shape while it grew on the surface. This project was our first attempt to characterize if this unusual phenomenon is statistically significant at a 95% confidence and ultimately predictable.

Poster - Course Project, 201880 CMM 390 P1 Goal 3: Good Health and Well-Being STUDENTS Franchesca Robin Hackworth ADVISORS Angeline L Sangalang LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The present investigation attempts to provide a more comprehensive investigation of stigma in media by exploring representations of two important stigmatized health contexts (mental illness and HIV/AIDs) in a representative sample of television programming. The study has three objectives: 1) identify the program types more likely to contain information about these stigmatizing health conditions, 2) explore differences in stigmatizing information present in each program type, and 3) explore similarities and differences between contexts. Findings from the investigation have the potential to provide insights for media literacy initiatives (i.e., identifying particularly problematic exposure points) and stigma reduction messaging (i.e., identifying specific cues that need to be corrected or dispelled through campaign or treatment efficacy messages). A television sample of 672 total hours of content was coded for mentions of HIV/AIDs and mental illness. Discussions of mental illness were about 10x more prominent than those of HIV/AIDs and across a diverse range of programming types, while HIV/AIDs mentions were limited to news, commercials, and talk shows. Mental illness content was often associated with the advertisement of a drug. Mental health has the potential to be more stigmatized because of its frequent presence. Local news contained the most content for both health issues (39% HIV/AIDs and 35% mental illness), followed by commercials (29%) and drama (19%) programming for mental illness and talk shows (35%) and commercials (17%) for HIV/AIDs. It may be possible that different production techniques and demands for different programs facilitate portrayals of health issues in different ways. An investigation such as this one allows for comparison between program type within the same time frame, an analysis that is missing from the present landscape of scholarship. We hope to provide directions for stigma reduction messages and areas of attention for media scholars.

After reviewing crime logs for 2018, the common crimes Public Safety are calling upon are substance possession, noise, burglary/theft, sexual violence, and rule violations/disorderly conduct. The goal of the study is to uncover the reasons why students are or are not calling Public Safety in the South Student Neighborhood when experiencing or witnessing one of these five crimes. The Health Belief Model will help guide the study and research for a better understanding of the perceived relationship between Public Safety and students. The Health Belief Model is typically used to predict individual's action, to prevent, screen, or control perceived risks. Understanding an audience's beliefs will help design safety campaigns appeal to target audiences in a persuasive and effective manner.

With Ohio being 4th in the nation for human trafficking, Dayton is not immune to this crisis. Widely known as “modern day slavery,” human trafficking can happen to anyone due to traffickers targeting basic human vulnerabilities. The media production students at the University of Dayton are working to create a documentary aiming to educate and start a dialogue in regard to this issue.Breaking the Silence: Uncovering Ohio’s Human Trafficking Crisis seeks to give survivors of human trafficking a voice. Through both interviews with the survivors and experts on the subject, the team will attempt to uncover the complexities of human trafficking. Hearing the stories of survivors and those affected by the issue will help audiences have a better understanding of how this happens right in front our eyes, and how to better combat this national problem. Our documentary seeks to increase the awareness of this seemingly voiceless issue. Anyone could become a victim of human trafficking, and it is important for everyone to come together in order to help fight this relatively unseen problem.

Wall Street Journal Reporter's Possible Conflict of Interest with Neighborhood Mosque College of Arts and Sciences: Communication Poster - Independent Research

STUDENTS Rachael Kay Haselhuhn ADVISORS Chad E Painter LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Paul Overberg, reporter for the Wall Street Journal and president of his community association in Fairfax County, is involved in a perceived or real conflict of interest regarding his complaints about a local mosque, the McLean Islamic Center. Through his role in the community association, Overberg made complaints about the mosque’s recent expansion, which simply allowed the morning prayer service to include more than ten people. He complained on the grounds that this expansion would cause more noise in early morning hours, and as a result, the McLean Islamic Center has had to spend thousands of dollars on traffic and noise-mitigation studies and lawyer’s fees. Many news organizations highly discourage their employees from getting involved in public or political issues because it could come into conflict with the journalistic norms of objectivity and neutrality. Although Overberg is not in direct opposition to the Journal’s rules, many respected journalists think he would be smart to step back from this issue, as it could be perceived as Islamophobic. Edward Wasserman, dean of the University of California at Berkeley Graduate School of Journalism, said “The Wall Street Journal should be worried that his involvement, even in a neighborhood squabble, will be viewed as religious intolerance”.This conflict of interest, or perceived conflict of interest, is in contention with many common values in the field of journalism, such as independence and loyalty. Should Overberg be free to participate in controversial projects, or should he remain loyal to a journalist’s obligation of objectivity in the public eye? This question and topic of research will be presented in a poster at the Stander Symposium and in a two to four page case study.

With more than 40 thousand #FyreFestival tags and models such as Kendall Jenner and Bella Hadid contributing to the promotion of the music festival, McFarland created a movement so big that there was no going back. Social media provided a platform so powerful that Fyre Festival was able to be taken to extremes. Originally intended to promote Fyre Media’s Fyre app for booking music talent, the festival soon became a weekend-long music festival on a private island with private jets, cabanas, alcohol, food, and so much more. Once they arrived, the 5,000+ festivalgoers that purchased tickets quickly took to social media to express their extreme disappointment. Coming full circle, social media provided a powerful platform to generate a movement from #FyreFestival to #FyreFraud.

SharkTank Deal Prediction: Dataset and Computational Model College of Arts and Sciences: Computer Science Poster - Course Project, 201910 CPS 596 03

STUDENTS Thomas Sherk ADVISORS Van Tam Nguyen LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 SharkTank is a television show where start-ups pitch their idea to a panel of five investors (sharks) in hopes of striking a deal in the form of equity or royalties for money and other business perks. Since its inception, SharkTank has been a center of discussion and analysis for fans, statisticians, and business people alike in hopes of cracking the code to the start-up world and figuring out the next big ‘thing’. Most of these discussions and analyses have come in the form of blogs, articles, and academic research. However, there has been a lack of complete datasets and application of computational models for further analysis. In this project, we investigate factors that play into the SharkTank deal. To this end, we first collect a new dataset, SharkTank Deal Dataset (STDD), by combining data from multiple public sources. The dataset includes descriptive features of each start-up and episode such as product category, team composition, valuation, equity offering, specific sharks that appear on that episode, and state origin. For the computational model, we propose the non-negative least square regression with regularization term to predict whether a start-up strikes a deal with a shark. We conduct experiments to demonstrate the superiority of our model over the baselines, namely, neural network, non-negative least square, ridge regression.

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Panchakshari Nijagunashivayogi Hiremath, Rakesh Sunkaralakunta Venkatarama Reddy ADVISORS Phu Huu Phung LOCATION, TIME Kennedy Union 311, 1:20-1:40 JavaScript is a scripting language used for almost every websites. JavaScript code is run in the user’s web browser with extreme security risks. For example, attackers can perform cross-site scripting (XSS) attacks on vulnerable websites to e.g., steal the user’s credentials or activities. In this work, we aim to prevent such potential malicious behaviors by developing a Chrome extension to monitor potentially malicious JavaScript actions. Any behavior violates a predefined policy is considered suspicious and will be blocked by our extension. An end user can use our extension to define their own policies to control the behaviors of websites so that they can protect themselves by potential attacks. We illustrate our prototype with several practical attack scenarios and demonstrate how our extension can prevent such attacks.

Adaptive Security Policy Enforcement Framework for Hybrid Mobile Applications College of Arts and Sciences: Computer Science Oral Presentation - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Rakesh Sunkaralakunta Venkatarama Reddy ADVISORS Phu Huu Phung LOCATION, TIME Kennedy Union 311, 1:40-2:00 The exponential growth in hybrid mobile applications has exposed itself into a wide spectrum of security risks. With the existing permissionbased security model provided by leading providers like iOS and Android, although mobile applications ask for permissions to access the resources, users can only grant or reject them. Our research work aims at addressing these limitations by enabling the user to customize the access permissions in the applications at run-time.By leveraging our adaptive security policy enforcement framework, the hybrid mobile application developer can inject a stream of security policies with basic configurations into the application. Once the application is installed on the mobile device, the user can explore the friendly graphical interface provided by the framework to customize the security policies to match the usage requirement. The extensive classification of fine-grained policies in the framework provides more flexibility in controlling the resource access permissions as per the need. This dynamic security framework is easy to use for mobile application users yet powerful enough to thwart any malicious attacks which compromise users' privacy or misuse of mobile device resources. We will illustrate the effectiveness of our framework by demonstrating the user-friendly interface for on-the-fly policy customization.

Improving Object Detection with Dual Mask R-CNN College of Arts and Sciences: Computer Science Poster - Honors Thesis

STUDENTS Yunheng Liu, Jinnan Yan ADVISORS Van Tam Nguyen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Object detection is crucial for real-world applications like the self-driving vehicle, search and rescue missions, and surveillance systems. Therefore, it is essential to accurately detect all objects in the field of view. While cutting-edge technologies like Mask R-CNN work in specific regions in images, therefore, some image regions are usually ignored one object is covered partially by the other. In our project, we improve the performance of object detection through a dual mechanism. In particular, our proposed framework removes the already-detected objects in the original image, then perform the detection process once again to force the attention to the ignorable regions. The final results are obtained by merging the two sets of detection results. We conduct experiments to demonstrate the effectiveness of the proposed framework.

Human-eyewear device interaction

College of Arts and Sciences: Computer Science Poster - Independent Research

STUDENTS Vamsi Charan Adari ADVISORS Van Tam Nguyen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The purpose of this project is to address the problem of interaction between the user and eye-wear devices. In particular, our framework recognizes audio instructions, hand gestures, and human gazes and translate them into commands. First, the audio input from the user is recognized and converted to text by using speech to text recognition system. Second, hand gestures are recognized based on the movements of finger tips in multiple frames. Third, the human gaze is computed as the average of the two distances captured from both eyes. To demonstrate these commands, we developed two applications to demonstrate the effectiveness of the new way of interaction.

Clothing garment swapping via pose estimation and thin plate splines College of Arts and Sciences: Computer Science Poster - Independent Research

STUDENTS Ganesh Mudduluru ADVISORS Van Tam Nguyen LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Online apparel shopping has huge commercial advantages and convenience contrasted with the traditional shopping but lacks the ability to physically inspect or try on the clothes. To solve this problem, we are working on a virtual try-on technology which has attracted a lot of interest recently by delivering product information similar to that obtained from direct product examination. It allows users to experience themselves wearing diverse garments without efforts of changing them physically. The traditional way of achieving this is by building a 3d model using computer graphics and render the output images. But these approaches require a lot of manual labor or expensive devices to gather necessary information for building 3D models and large computations. In this project, we first perform pose estimation to detect the body joints and these body joints help us identify the corresponding clothing garments. Then, based on the clothing garments, we do body morphing via thin plate splines transformation. We later port the clothing garments from the source to the target human. We conduct different experiments to demonstrate the effectiveness of our work.

We also analyzed other universities’ resources and materials, which showed that many other schools similar to UD in size and demographics had resources such as support groups, special events, and easily accessible information on eating disorders and related resources on the institution's website. For this project, we made recommendations for improving UD’s resources and we wrote and designed a fact sheet specifically for UD students that provides necessary information on eating disorders that could be made available at various locations on campus, such as academic buildings and residence halls.

LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Low health literacy serves as a distinct barrier for proper healthcare and affects a large portion of the U.S. population. Our team’s goal was to revise a brochure about headaches to fit the reading level and educational goals of the students in UD’s Intensive English Program (IEP). Our team performed a Health Literacy Load Analysis, SMOG test, and Word readability test to analyze the literacy of a headache brochure from Dr. Schneider’s Clinic, a headache and back clinic in Indiana. The results of these tests found that the reading level of the original document was much higher than the IEP students’ third to fourth grade reading level. We made two visits to the IEP class. The goal of the first visit was to find out what the IEP students already knew about headaches and what information they still wanted to know. Then we revised our existing brochure so that it matched the IEP students’ health literacy levels and incorporated the information that matched their interests. In the second visit, we field tested the revised brochure and received additional feedback from the IEP students to create a more effective final brochure. We were successful in lowering the readability of our brochure from an 11th grade reading level to a 5th grade reading level by replacing complex words and ideas with simpler terms. This project directly shows the need for health materials that are cognizant of individuals with lower health literacy.

Adjusting the existing health documents to raise awareness about health risks of smoking for the Intensive English Program students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Lauren Brooke Alvarez, Jake Michael Knight, Teresa Yuk Yu Wong ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Far too often in the U.S., healthcare documents are published at a level of reading well above what the intended audience can comprehend. When people cannot comprehend health-related materials, they are said to have low health literacy, which involves the wide range of skills and competencies to comprehend, evaluate and use health information to make informed health-related decisions to lower their health risks. Inability to read patient education materials can lead to poor overall health and high mortality. For this project we partnered with students in UD’s Intensive English Program (IEP), and revised two existing healthcare documents on smoking, a topic that was of interest to them, and made a single document that was more readable and useful for the IEP students. During this project, we tested the readability level of both the original documents and the revised brochure using the Microsoft Word test, SMOG test and the Health Literacy Load Analysis test to ensure the readability level was appropriate for the IEP students who read at a 3rd to 4th grade level to comprehend. Based on the results of our research, we reduced the reading levels of the original documents from a 10th and 11th grade level to a 4th and 7th grade level. We also visited the IEP students twice to collect information that they would like to know about our topic and to field test a draft of our brochure. In the end, our goal was to provide these students with a readable, informative, and useful document that can help them better understand the health effects of smoking, the health risks of secondhand and thirdhand smoke, and the reasons that smokers continue to smoke so that they

Revising a Document About Sugar and the Body for UD Intensive English Program Students College of Arts and Sciences: English Poster - Course Project, 201910 ENG 366 01 Goal 3: Good Health and Well-Being Goal 10: Reduced Inequalities STUDENTS Nicholas Bianco, Patrick William O'Brien, Katie Marie Perry, Janeta Y Yancheva ADVISORS Ann E Biswas LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Having adequate health literacy is important in order for someone to be able to understand medical information that is presented to them. On UDâ&#x20AC;&#x2122;s campus, a large number of international students speak English as their second language. For this project, we worked with the Intensive English Program (IEP) students to create a brochure about sugar and the body that is more understandable and usable for their literacy level. We met with the IEP students at the beginning of the project to see what they already understood and what they wanted to learn more about. While the average American reading level is 8th grade, the IEP students in this course read at approximately a 3rd-4th-grade level. The goal of our project was to modify an existing document to make it readable and usable for the IEP students. The document we chose came from betterhealth.vic.gov.au. We first analyzed the four domains of health literacy by performing a Health Literacy Load Analysis in order to improve the readability in our final brochure. We field tested the draft with the IEP students once more before finalizing the brochure to gain feedback on their understanding of the material. The completion of the final document was followed with a SMOG and Word test and determined that the reading level was reduced significantly. This project showed us that it is possible to reduce a health document to a lower reading level in order to more effectively communicate health information.

Native and Non-Native English Teachers College of Arts and Sciences: English Poster - Graduate Research

STUDENTS Rowaida Hamad S Alhabis ADVISORS Margaret M Strain LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Over the years, English has rapidly grown to the extent of outrivaling languages such as French which were previously prestigious. Englishâ&#x20AC;&#x2122;s accelerated development arises from the fact that it can be easily learned. Non-native speakers often opt to learn English as their second language. Consequently, this language has emerged as the preferred communication medium in most institutions, organizations and professional circles worldwide. Globally, everyone is striving to improve their competence in English. In their efforts, the majority often opt to enhance their expertise through the assistance of native speakers. Due to the enormous number of English Learners worldwide, it is obvious that most English teachers are non-native English speakers, and should not be looked down upon. According to David John Brining, non-native English teachers are faced by uncertainties when speaking the language they have to teach, and may therefore take on an aggressive attitude towards teaching the language (50). They become obsessed with the grammar and ignore minor but significant elements like linguistic appropriateness. However, he adds that non-native speakers are the best teachers since they can easily communicate with non-native students, as they have been through the process of learning English as a second language. In addition, Enric Llurda disagrees by pointing out that a lot of non-native English speakers have adopted English as their L1, and with the exemption of an accent, there is merely a distinction between them and native English teachers (118).The preference of native English speaking teachers is fuelled by the notion that they are inherently superior to their non-native counterparts. This presumption frames the focus of interest in this examination. The research specifically challenges the notion that native speakers are inherently superior teachers of English, compared to their non-native counterparts, through a detailed review of selected studies and an analysis of primary information collected from surveys. I hope to convince students that professionals who teach English as their second language are equivalently competent as their native colleagues.

Disciplines in the Write Place: An Assessment of the University of Dayton’s Writing Center College of Arts and Sciences: English Oral Presentation - Graduate Research

STUDENTS Emily Rose Stainbrook ADVISORS Christina M Klimo, Patrick W Thomas, Stephen W Wilhoit LOCATION, TIME Kennedy Union 312, 10:20-10:40 Over the last few years, Christina Klimo, the Director of the Write Place (WP) at the University of Dayton (UD), has noticed a trend in the descriptive statistics of the WP. Undergraduate students, especially those from disciplines other than English, stop visiting and utilizing the WP after their first two years. The WP was designed to be a resource for the entire student body; if a portion of the student body feels that the WP is not offering services they need, then the WP is failing its mission. Klimo and I came up with two explanations for why students from disciplines other than English stop visiting the WP: it could be a marketing problem—the WP may have difficulty informing students that it is a resource—and/or a perception problem, each requiring a different remedy. A problem with perception exists when the WP’s reality does not meet the student’s perception of the WP. The WP employs “generalist” peer tutors, who are often unfamiliar with the content and academic discourse conventions of disciplines other than their own. A student who expected a session with a specialist tutor may view the center unfavorably if s/he has an unproductive session with a generalist tutor. This problem may combine with marketing shortcomings to explain this phenomena. Because the WP does not possess data on any of these potential issues, my assessment will have to determine if any of these problems exist and to what extent they influence the answer to my research question.

Appalachian Subcultures

Oftentimes, when people think of the Appalachian region or Appalachian culture, the image of the hillbilly comes to mind. Pop culture, through films like Deliverance and reality TV shows like Buckwild and Moonshiners, has helped perpetuate the notion that the Appalachian region is populated solely by uneducated and untamed Caucasians. However, true Appalachia is made up of a diverse and complex range of subcultures. Spanning an area from New York to Alabama, the Appalachian region is home to a plethora of vibrant communities, each of which has its own unique and colorful history. Appalachia is an amalgamation of cultural and racial identities. Among these are Native Americans, the Scotch-Irish, and Affrilachians, to name but a few. Our poster presentation seeks to demonstrate the diversity of Appalachia through statistical and literary evidence that embodies the experience of these marginalized groups popular media has neglected to represent accurately or fairly.

“mommy blogger” convicted of killing her only son, and Adrienne Rich, celebrated feminist academic and poet, are put into conversation in order to examine radical embodiments of motherhood. I analyze Spears’ blog, which details her experience as she cares for she fabricated for her son in addition to Rich’s seminal work, Of Woman Born: Motherhood as Experience and Institution. With the testimony provided in these writings, I examine what it means to be a both a mother and a criminal, and a mother who transgresses expectations of femininity. Ultimately, this thesis is an attempt to understand the banal evil of structural poverty and the conditions it creates that allow brutality to be perpetuated by the least likely of sources: society’s ultimate care-giver, the mother.

Morality Within & Without: Children's Literature College of Arts and Sciences: English Porch Project - Honors Thesis

STUDENTS Anna E Edwards ADVISORS Stephen W Wilhoit LOCATION, TIME 340 Stonemill Road, 1:00-1:30 There are works of children’s literature that have become commonplace in both our bookshelves and hearts. However, I want to know whether or not it is moral for adults to enter into the childhood imagination in such a way. After all, even in its name it is apparent that such a place is for children and not adults. Thus, this thesis investigates how one can morally write children’s literature and what this process involves. A journey that not only involves Alice’s Adventures in Wonderland by Lewis Carroll and The Complete Adventures of Peter Rabbit by Beatrix Potter, but also Aristotle’s virtueethics, the road to finding a moral approach is unsurprisingly long-winded. However, this is a philosophical road worth taking and I believe essential to the future of all children’s literature.

of storytelling in confronting trauma. My literary analysis reveals that the child’s voice points to underlying forces of historical, political and economic exploitation, and marginalization. Displacement, Social Injustice and Trauma are the major themes arising from my research. All these themes indicate irresponsible adult-led national, international, socio-political and economic networks and practices. Through the capacity of the child’s perspective to cross taboo lines and the adult shame frontier, and to penetrate emotional danger zones easily, my research shows that the child’s voice exposes how adults within child soldier spaces and beyond, are flawed and limited by their participation in social, cultural and ideological institutions and discourses.

Over the 2019 winter intersession, 17 students traveled to China to see technical writing and localization in action in a given global context.In the weeks prior to the departure, students attended lectures to understand the fundamentals of technical writing such as audience, purpose, and contexts and how language, culture and globalization impact translation, localization, and technical writing practices in global contexts. We surveyed the development of technical writing in China and discussed both the opportunities and challenges for technical writing practices in China. During the two weeks in China, students visited 8 companies and 2 universities in 4 cities, listening to presentations given by technical writers in China, observing their working environments and analyzing their final deliverables, and talking with or interviewing professionals, both Chinese and non-Chinese who work in China, about their backgrounds, skills, and daily practices. They conducted secondary research of each company before the visit. Working as a team, students reflect and showcase what they have learned about professional and technical writing in China through synthesizing observation, interviews, and online research and comparing with technical writing practices in American companies. Based on their research and analysis, four teams offer recommendations to Chinese companies such as Alibaba, Lenovo, Huawei, and CSOFT on how to localize in the US and survive in the US market. One group of students proposed to Beijing University on developing a technical communication degree program similar to the Human-centered Design and Engineering programs at University of Washington.

A Tale of Two Spies: Racial Misidentification and Hyphenated Identities in Danzy Senna's Caucasia and Chang-Rae Lee's Native Speaker College of Arts and Sciences: English Oral Presentation - Honors Thesis Goal 10: Reduced Inequalities STUDENTS Will Edward Landers ADVISORS Thomas L Morgan LOCATION, TIME Kennedy Union 310, 3:00-3:20 I deploy critical race theory in a literary examination of passing and racial normality in Danzy Senna’s Caucasia. I focus on Senna’s character of Birdie, an African-American, biracial girl whose appearance is racially ambiguous. I then draw comparisons between Birdie and the character of Henry Park, a Korean-American ethnic spy in Chang-Rae Lee’s Native Speaker. Birdie’s experiences demonstrate incongruencies between visual racial expectations in the United States. Henry’s experiences show the expectations of cultural newcomers to the U.S., as well as the ways that racism is learned by Korean immigrants. Both Senna and Lee use the figure of the spy. Birdie speaks of feeling like a spy and uses her appearance as a disguise, while Henry is employed as a professional spy due to his Korean-American background. The cultures of these characters are different, but their stories as spies reveal key similarities in their American experiences. Historical tensions of race and class

divide Korean-Americans and African-Americans, relative newcomers and old residents. However, in the presence of white normality, each group faces some similar challenges to surviving and finding a place in white American society. Racial identities are shaped by the white gaze and, in turn, the perceptions of others groups are formed against a white background.

How much power should we vest in the President? Is there value in reexamining what we value as American citizens? These are the questions asked by four former presidents: Turner Walsh, Harlan Rowe, Andre Hall, and Ivy Caine. Brought together by the uncertainty created by current president, Louis Blunt, these four former titans of the American political machine must decide where their allegiances lie. Are they dedicated to the preservation of America and its people or just in protecting their own self interests? These questions are answered in the seven-episode audio drama, Echo Protocol. How does a podcast come to be? Tracing from inception to final edits, one can see how a podcast moves from small idea to a full-fledged mini-series. Focusing on themes of power, corruption, and the corruption of American politics, Echo Protocol attempts to answer why we choose to place certain people in positions of great power and responsibility. Hearing from the creator, actors, and the audio engineer, the story of Echo Protocol is brought into view not only as a creative endeavor but also as a reflection of our current social and political climate.

The factors that lead Non-Native English Speaking Students to Plagiarize in Higher Education: Teachers and Students Perspective College of Arts and Sciences: English Poster - Capstone Project

STUDENTS Salha Ahmed M Alahmari ADVISORS Fatima A Esseili, Margaret M Strain, Tereza M Szeghi LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The factors that lead Non-Native English Speaking Students to Plagiarize in Higher Education: Teachers and Students PerspectiveOver the past years, the number of graduated from institutions of higher learning has increased gradually. This can be attributed to the increasing demand for well-educated individuals in the job market. However, the job market has increased its demand for the quality of graduates. This can be attributed to the fact that most students who graduate from these institutions of higher learning barely produce their work. Most of these students practice plagiarism. Plagiarism still is a relevant problem to this day. This happens to be the case especially among nonnative English speakers, who find it hard to cope with the strict rules on plagiarism. Most of these students lack the confidence in themselves to produce good quality writing. They therefore “borrow” from other more proficient writers (“(PDF) Plagiarism awareness, perception, and attitudes among students and teachers in Swedish higher education - a case study,” n.d.), which is wrong. With the increasing cases of plagiarism, one tends to wonder whether the institutions of higher learning are doing their part in ensuring that plagiarism is curbed at its core. In spite of putting in measures such as expulsion for students found guilty of the act, plagiarism is still practiced in these institutions. Taking a closer look, one could ask whether the teachers are doing enough to ensure their students are doing enough to ensure that this crime is not committed in their classes. This study will look at the plagiarism and the role that both the teachers and students play in enhancing it.

Mortality in the 21st Century: A Cycle of Short Stories on Death and the Afterlife College of Arts and Sciences: English Poster - Honors Thesis

STUDENTS Rose Ann Rucoba ADVISORS Albino Carrillo LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Every culture and religion around the world has different beliefs and theories about why humans die and whether or not there is something more beyond death. Authors such as Elizabeth Evans, Flannery O’Connor, and Stephanie Vaughn are three modern-day, impactful writers who have explored the themes of death and the afterlife in their own works.In response to and in dialogue with these writers, I have completed a collection of five short stories. This cycle of short stories focuses on the themes of death and the afterlife. The stories are separate from each other and are told from different points of view, following a variety of characters as each struggles with the inevitability of death and the afterlife that follows. This cycle includes both popular religious and non-religious perspectives on death and the afterlife, and also investigates

After several months of communication, collaboration, and community input, DCS members began to brainstorm the challenges and assets in the Five Oaks community. Once the park was identified as an asset, but something community members wanted to improve, DCS worked with the FONA president to refine project ideas. The four projects DCS and FONA decided to create were a mural for the picnic shelter, soccer goals, little libraries for the park, and a walking path to connect exercise equipment. These four projects were selected because of community input and DCS member interests. The DCS members see these projects as meeting the needs of the community and adding to the park's function as an asset. The proximity of DECA prep to the park increased the ability to engage students and community members in physical and mental wellness. This made these four projects a top priority for DCS and

College of Arts and Sciences: Geology Poster - Capstone Project

STUDENTS Michael Chacko ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Infant mortality is one of the most important indicators for the overall health of a community. Infant mortality is defined as number of deaths per 1000 live births of children under one year of age. The leading causes of infant mortality include premature births, birth complications, smoking/drinking of mothers while pregnant and environmental conditions. In this project, we explore the relationship between infant mortality rate and such factors as race, income, tobacco/alcohol, and maternal health in Santa Clara County, California, using data acquired from the Santa Clara County Public Health Department. With a population of around 2 million, 53% consisting of white, 3% black, 37% Asian, 25% Hispanic, and 8% living in poverty, Santa Clara is a diverse enough county to perform this study and gain insight on the community health in the area. Previous research has determined that African-American mothers experience infant mortality at a rate 44% higher than average. Lower incomes tend to correlate with higher infant mortality rates, as they do not have the resources to afford medical care. The aim of this project is to find out if these results from previous studies will hold true in Santa Clara County. The external health factors to be analyzed are the number of alcohol and tobacco retailers per square mile in Santa Clara County. Maternal health factors will be evaluated through a Vital Health Statistics dataset obtained from the County Public Health Department. Using GIS, we will also explore how such relationship varies spatially across the county. This information will be useful in gaining a deeper understanding of the rates of varying infant mortality in the county and will highlight zip codes of particular interest regarding infant mortality.

New Natural Gas Site Locating in the Marcellus Shale Region PA College of Arts and Sciences: Geology Poster - Capstone Project

STUDENTS Ryan P Young ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Natural gas is an important resource for many various reasons. In the current study, I aim to identify the best suited location for a new well using various factors and restraints. This resource is stored thousands of feet beneath the Earthâ&#x20AC;&#x2122;s surface, specifically in shale bearing layers. One shale unit in particular, the Middle Devonian Marcellus Formation, is of particular interest. It extends approximately six-hundred miles, covering large areas of the Appalachian Basin including Pennsylvania, West Virginia, Ohio, and New York. The area underlain by the Marcellus Formation is nearly 240,000 square kilometers (Kargbo et. al., 2010). However, most of the natural gas is located underneath Pennsylvanian land and therefore this state will be the focus of the study. Recent advancements in the extraction of this resource have led to an exponential increase in this industry. New techniques known as hydraulic fracturing and horizontal drilling have greatly influenced the efficiency of the process and therefore economic prosperity. Just in Pennsylvania alone, 2008 estimates show the creation of more than 29,000 jobs and $2.3 billion dollars in revenue (Kargbo et. al 2010). A previous study by Meng (2014) revealed significant landscape variables as driving mechanisms in well-site location. Higher elevation and wetlands were shown to be the most prone to natural gas sites while steeper slopes were correlated with lower probabilities. I will apply his findings and the use of GIS techiniques to identify the most suitable location for a new fracking site. For each of the variables, a suitability layer will be created. Once all of these layers are created, they will be combined in order to acquire an overall suitability score to determine the best suited location.

Air Pollution and Environmental Justice College of Arts and Sciences: Geology Poster - Capstone Project

STUDENTS Alan Matthew Theisen ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The air quality throughout the state of California varies from county to county. California also contains several large urban areas with a diverse population of varied racial and socioeconomic background. The aim of this study is to examine how people of different race and socioeconomic status are affected by air pollution as indicated by PM2.5 (particulate matter <2.5Âľm). PM2.5 is known to trigger and worsen chronic diseases such as asthma. In this study, we are going to examine (1) the links between asthma and PM2.5; and (2) the associations between PM2.5 concentrations and the socio-demographic characters of the population. We are also going to examine how such relationships vary in space through geographically weighted regression models. Investigating air quality with a focus on environmental justice helps us to consider the inequalities of more vulnerable social groups, and can help us learn more about what can be done to mitigate such inequalities.

Convention on the Law of the Non-navigational Uses of International Watercourses in 1997, which attempted to set standards around the usage and conservation of watercourses. Though this convention can help resolve the geopolitical tension over the GERD’s construction on the Nile River, it does not solve the question of Ethiopia’s right to build a dam that could impact other countries water supply. Therefore, in 1999, the Cooperative Framework Agreement (CFA) grants each country that the Nile River flows through, the right to adequately use the Nile's water supply. However, Egypt is one of the countries that originally did not sign the CFA. The Nile is Egypt’s primary source for freshwater. Egypt’s main concern is since their population continues to grow, their freshwater supply will deplete. Though it may be perceived to negatively impact Egypt, the GERD seems to benefit countries, especially Ethiopia and Sudan, in terms of economic development. Hence, I am to explore how the GERD will benefit and restrict Ethiopia, Sudan, and Egypt’s commercial growth. I will also explore journal articles and media sources to further analyze the complex geopolitical situation in northeastern Africa.

Land Cover Change and Biological Invasion: Chinese Tallow Tree in Eastern Texas College of Arts and Sciences: Geology Poster - Capstone Project Goal 15: Life On Land STUDENTS Emily Elizabeth Jones ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Chinese tallow, Triadica sebifera (L.) Small (Euphorbiaceae), is one of the most pervasive invaders of in the southeastern United States. In various ecosystems, Chinese tallow forms dense monocultures, displacing native species at multiple trophic levels and potentially facilitating the invasion of other non-native species. To mitigate the spread of this species, researchers have attempted to identify areas especially prone to invasion, historically using environmental and climatic data. Recent studies suggest, however, that anthropogenic disturbance may be a powerful driver of this species invasive success. The goal of this study is to determine if Chinese tallow range expansion in eastern Texas is correlated with anthropogenic disturbance, using land cover change as a proxy. To achieve this, Chinese tallow abundance data from multiple Forest Inventory Analysis surveys (2001-2017) will be compared with historical national land cover data (2001, 2006, 2011) from 42 counties in Texas using correlation analysis. Based on existing research, we hypothesized that Chinese tallow abundance will be related to changes in land cover - correlating positively with increases in developed land, agricultural land, and forested land. The findings of this study will inform scientific understanding of the relationship between anthropogenic disturbance and species’ invasions and could assist land managers in identifying areas prone to invasion by this pervasive weed.

Future Impacts of Sea-Level Rise on Miami, Florida, USA. College of Arts and Sciences: Geology Poster - Capstone Project Goal 13: Climate Action STUDENTS Hannah Reid Butler

COLLEGE OF ARTS & SCIENCES

ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 This project aims to analyze the impacts of sea-level rise on the coastal city of Miami, Florida. Rising temperature is causing the melting of land-based glaciers and the thermal expansion of the ocean. Both of these factors have led to sea-level rise. This will affect people living in coastal areas. Using a Geographic Information Systems (GIS) approach, this project will first identify inundated areas based on future sea-level rise projections for the year 2100. The census blocks inundated by this rise will then be analyzed based on socioeconomic factors such as race, income, and age. This information will identify any demographics being affected by these issues of climate change. This project will give insight into the affects of future climate change and give those who will be affected a chance to prepare and build resilience to these changes.

GIS-Based Habitat Suitability Analysis for the Eastern Hellbender College of Arts and Sciences: Geology Poster - Capstone Project Goal 15: Life On Land STUDENTS Emma C Yanosko ADVISORS Shuang-Ye Wu LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The Eastern Hellbender is North Americaâ&#x20AC;&#x2122;s largest amphibian species and is in great danger of extinction. A good understanding of its spatial distribution is very important because the species is a biological indicator for good water conditions. Keeping this vital species off the endangered list is advantageous for preserving biodiversity in our streams. The aim for this project is to determine the most suitable habitat range for the Eastern Hellbender based on the factors that most affect its distribution. First, we will identify the most significant factors that are affecting the population of the hellbender. The six factors chosen are as follows: land cover, elevation, slope, water temperature, water pH, and proximity to dams. A suitability map will be created for each of the criteria. All of the six suitability maps will be overlaid to create a complete suitability map. This suitability map will then be compared to the actual current species range of the Eastern Hellbender so that its accuracy can be assessed. This information could provide insights into the species dynamics, as well as the design of protection plans and conservation strategies.

history of which has been hotly debated for decades. To resolve this debate, we collected a WNW-trending transect spanning 20 km of muscovite, biotite, and/or potassium-feldspar bearing samples for dating by the 40Ar/39Ar method. This method allows us to model the timing and progression of cooling, and therefore the uplift history of these rocks. The results from the southernmost transect indicate an early phase of cooling prior to 35Ma (See companion presentation by J. Jeruc). Here, I present results from the western flank of the range that record a later phase in the cooling history. A series of five samples from this transect imply that cooling below 200°C began prior to 30 Ma. The samples then cooled slowly until about 20-24Ma, when they experienced a reheating event to above 250°C. Following reheating, the samples cooled rapidly to below 100°C between 20 and 14Ma, with cooling occuring progressively later towards the WNW. The termination of cooling at 14 Ma is in excellent agreement with fault gouge dating results reported by Haines and van der Pluijm (2010). The progression of cooling ages implies that unroofing proceeded at a rate of 1.8 - 2.4 km/m.y. Although some researchers suggest that the chief trigger of this phase of extension was the drifting of western North America over the Yellowstone hotspot, these results indicate that the onset of extension predated hotspot related volcanism by at least 3 m.y.

Late Eocene Onset And Progression Of Extension With Exhumation In Southeastern Humboldt Range Nevada College of Arts and Sciences: Geology Poster - Capstone Project

STUDENTS Joseph William Jeruc ADVISORS Allen J McGrew LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The East Humboldt Range (EHR), located in northeastern Nevada, includes metamorphosed rocks surrounded by sedimentary rocks. Transportation of this metamorphic core complex to its present location includes a dimension of vertical uplift, along with regional extension. The metamorphosed rocks of the EHR include minerals capable of recording temperature histories associated with rising from mid-crustal depths. A recently discovered kyanite-bearing schist in the southeastern EHR requires peak pressures and temperatures above 7 kb and 625oC, implying tectonic burial to depths >22 km. This deep-seated metamorphic terrain lies < 500 m beneath a large scale fault system known as the Ruby-EHR detachment fault inferred to have caused its exhumation.To determine timing and progression of uplift beneath this fault, mineral samples collected along a 20 km WNW-trending transect mimic the direction of gradual exhumation from depth. Sampled minerals, including biotite, muscovite, and K-feldspar, are dated using 40Ar/39Ar thermochronometry. These data record cooling through a temperature unique to each mineral known as its closure temperature. In addition, the diffusive loss of argon from K-feldspar allows modeling of cooling histories over a range extending from 450oC to <150oC. The initial phase of cooling beneath the normal fault system and the onset of uplift on the detachment fault occurred from 42 Ma to 35 Ma. Following initial cooling and extension, K-feldspar modeling reveals a reheating event after 28 Ma, and return to cooling signifying renewed extension (See companion presentation by A. Carte). The second cooling event occurs across a range of dates from 26 Ma to 14 Ma from the southeast to northwest. Comparing cooling ages along the transect, records a westward propagating wave of rapid cooling consistent with rotation of the fault to its current angle. Thus it supports the tectonic process of rolling hinge style exhumation.

Computer-Assisted Graphic Correlation of Ordovician Conodonts and Graptolites from the Argentine Precordillera and western Newfoundland using Constrained Optimization (CONOP9) College of Arts and Sciences: Geology Poster - Honors Thesis

STUDENTS Andrea Marie Bryan ADVISORS Daniel Goldman LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The purpose of this project was to use the stratigraphic range data of two extinct marine micro-fossil groups, conodonts and graptolites, to construct a composite range chart and correlation model for Ordovician age strata in Argentina and Newfoundland. These two locations were part of the eastern portion of the paleo-continent Laurentia. The goal was to integrate range data from organisms that occur in different rock types, limestones and shales, using computer-assisted graphic correlation techniques. Graphic correlation is the comparison of specific rock units by the presence of similar fossils found within them using a bi-variate plot and line of correlation. It is used to find a better estimate of the fossil duration in the earth’s history. The end result is a composite range chart, which shows the composite range of the organism in comparison to a timescale. The composite range chart constructed from the Ordovician rocks of Argentina and Newfoundland was used to answer questions on the viability of using CONOP9 to compare two different bio-facies. This research is important because the composite range chart provides paleontologists with a tool for studying and dating the rock record. Better estimates of fossil ranges can be used to make the geologic timescale more precise.

American Catholic: Scott Hahn and the Theology of the Catholic Right College of Arts and Sciences: History Oral Presentation - Graduate Research

STUDENTS Sean S Martin ADVISORS William V Trollinger LOCATION, TIME Kennedy Union 211, 2:00-2:20 Franciscan University of Steubenville professor of theology, Scott Hahn, is one of the more prominent voices in today’s American Catholic culture. He is a much sought after public speaker and his books are often presented, studied, and even at times given away by a many Catholic parishes. It would be hard to underestimate the import of Hahn’s thought on the American Catholic Church. Given the wide availability of Hahn’s work, his massive public following, as well as his influence on the students and priests coming out of his university, it is crucial that we understand exactly the theology that Hahn presents to his wide-ranging audience.Throughout the course of Hahn’s career, Hahn has spoken widely on Catholic theology, philosophy, spirituality, and biblical exegesis. In his varied writings, Hahn offers specific argumentation in support of his own unique positions. Controversially, however, Hahn describes his position as nothing more than accepted, traditional teaching of the Church. There is, of course, quite a massive difference between a theologian arguing that their theological position is the one that best understands the traditional teachings of the Catholic faith on the one hand and claiming that one’s own theological take is nothing more than an explanation of accepted teaching on the other. Hahn’s voice would not be nearly so problematic but for the fact that there has been virtually no scholarly engagement with Hahn and the claims he makes. This project demonstrates both the centrality of Hahn’s influence with the American Catholic Church and the failure of his theological offerings aligning with the tradition of the Church.

The Laggard Leader: A Historiography of the Origins of Wage and Income Inequality in the United States, 1973-84 College of Arts and Sciences: History Oral Presentation - Honors Thesis

Goal 10: Reduced Inequalities Goal 8: Decent Work and Economic Growth STUDENTS Nate Paul Sikora ADVISORS William V Trollinger LOCATION, TIME Kennedy Union 331, 3:00-3:20 Since 1973, income inequality has increased dramatically in the United States. Workers who entered the labor market in the 1970s, 1980s, and 1990s did not inherit the same economic security as their predecessors during the "Golden Age" of Capitalism. Their jobs paid relatively lower wages, unionization rates were half the rate they were in the 1950s, and fewer jobs offered the benefits associated with the traditional middle-class lifestyle. After 1973, increases in income growth have been heavily concentrated at the top of the income distribution while wages and incomes for workers at the bottom have stagnated for decades. What economic factors during the 1970s created a distinct shift towards rising income inequality? Lacking consensus among scholars, this work historiographically analyzes the various explanations put forth by economic historians and labor economists over the origins of income inequality in the United States.

A Hybrid Tree Method Using Heston-Hull-White Type Models College of Arts and Sciences: Mathematics Poster - Graduate Research

STUDENTS Nouf Alsomali ADVISORS Paul W Eloe LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In this poster, we consider a recently introduced hybrid tree pricing model. We consider the case where there are two stochastic processes and we consider the Heston-Hull-White model, and a generalized Hull-White stochastic interest rate model. We build two trees (X, V) and then take the cross product to construct the mesh of the tree. We then predict prices analogous to the binomial asset pricing model. To validate the model we compare the results to a simulation using the Monte Carlo method. We shall consider the case where there is zero correlation between the two stochastic processes and the case where there is nonzero correlation between the two stochastic processes.

A Cross-national Study of Whole Number Addition and Subtraction College of Arts and Sciences: Mathematics Poster - Independent Research Goal 4: Quality Education STUDENTS Mary Margaret Ghiloni ADVISORS Rebecca J Krakowski LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 While mathematical fluency is of great value in everyday life, in a changing world where information is easily accessible to students, problem solving skills and deep understanding of why math works over how it works is of more value and can be applied to both mathematical and non mathematical situations. When students move on from formal schooling and take their place in the “real world,” they will excel when they have the skills to create new ideas, evaluate new and existing ideas, and defend their own will allow students to effectively analyze the world around them. This study examines 1st-3rd grade textbooks from Singapore, Finland and the United States in an effort to pinpoint how these countries develop mathematical concepts. In particular, this study looks at whole number addition, subtraction by analyzing textbook problems, how they utilize different representations, algorithms and cognitive levels. This study increases our understanding of how math is being taught in different countries and how this might contribute to disparities in international test results.

Picard's Successive Approximation vs. Banach's Contraction principle College of Arts and Sciences: Mathematics Poster - Capstone Project

STUDENTS Leah Marie Squiller ADVISORS Muhammad N Islam LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The existence of a unique solution to the initial value problem: x^' (t)=f(t,x(t)),x(t_0 )=x_0 can be obtained employing Banach’s contraction principle or Picard’s successive approximation method. Generally, the norm that is used in the contraction principle is the supremum norm that requires a condition that is not needed in the successive approximation method. Therefore, it seems as if the successive approximation method is a superior method. The objective of this project is to show that these two methods are equally efficient. This is due to the fact that the condition that was needed in the contraction principle can be eliminated by using a different norm that is equivalent to the supremum norm.

Statistical Analysis of the Effectivity of A Quarterback to Increase Winning Percentage Over Time College of Arts and Sciences: Mathematics Poster - Capstone Project

STUDENTS Kaity M Jones ADVISORS Ying-Ju Chen LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 A quarterback is often seen as the key component to a winning football team. This study is meant to evaluate the quarterback only skills and how effective they are in increasing winning percentage over 11 years across all 32 NFL teams in the regular season. Longitudinal modeling is used to evaluate each variable independently of one another to see how they affect winning percentage when incorporated into the same model. This research will also compare to a previous model I developed for a previous class. The hope is to take up to 10 different variables and see which variables are significant in increasing winning percentage for the team. It will also show if over time variables become more or less significant as the previous model was only capable of holding 4 years of data compared to the revised model of 11 years. The model is meant to see which skills are significant to increasing winning percentage. Which will narrow the scope of a quarterback on what skills to work on for the greatest results. Ultimately it is meant to show the meaningful work that a quarterback actually puts in to helping his team win.

Lights Out - An Exploration of Domination in Graph Theory College of Arts and Sciences: Mathematics Poster - Course Project, 201910 MTH 466 01

STUDENTS Christian Steven Hemsath ADVISORS Aparna W Higgins LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 A graph is a mathematical object that consists of two sets: a set of vertices and a set of edges. An edge joins two vertices and depicts a relationship between those vertices. The following is a project for MTH 466 - Graph Theory and Combinatorics. Consider each vertex in a graph being associated with a light and with a button. Each push of the button will change the state of the light from on to off, or from off to on. Additionally, the state of each vertex joined by an edge to the vertex in question is changed. Given a graph with all vertex lights on, does there exist a set of light buttons which, when pressed, will turn off all vertex lights? An exploration of several examples of this question for different graphs is presented. It will also be proven that, for any connected graph, there exists a sequence of light buttons which when pressed will turn off all vertex lights.

A graph is a mathematical object that consists of two sets, a set of vertices and a set of edges. An edge joins two vertices and depicts a relationship between those vertices. Using vertices to represent states and directed edges to represent a transition between states, we can construct digraphs to model the Wine Bottle Problems. These problems ask how few pourings are needed to distribute specific amounts of wine amongst a set of unmarked bottles knowing only the capacity of each bottle and the total amount of wine. We will model problems such as finding the minimum number of pours required to distribute 8 liters of wine evenly into 2 bottles using only three bottles that have capacities of 3, 5, and 8 liters of wine. We will also explore properties of these digraphs.

Steady States of Gene Networks with AND/OR Gates College of Arts and Sciences: Mathematics Poster - Honors Thesis

STUDENTS Nikki Nicole Geiser ADVISORS Alan A Veliz-Cuba LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Boolean networks are systems of variables that are either ON/1 or OFF/0, and a set of rules/functions that describe how these variables interact. These networks can represent biological systems and their regulation/gates. An important feature of Boolean networks is its steady states, which represent values of the system that remain stable over time and correspond to biologically stable patterns. Finding the number of steady states is very difficult, so theoretical results that predict the number of steady states are fundamental for the understanding of Boolean networks and their applications. Thus, we focus on a specific class of Boolean networks: AND-OR gate networks with chain structure, where activation is either synergistic or independent, and which resemble the structure of signal transduction networks. We find closed formulas for subclasses of these networks and recursive formulas in the general case. Our results allow for an effective computation of the number of steady states.

Developing a Model for Clinical Song Analysis, or Why Music Therapists Still Need Music Theory and Musicology College of Arts and Sciences: Music Poster - Honors Thesis

STUDENTS Lesley Louise Wray ADVISORS Samuel Noah Dorf LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Music therapists use songs in a variety of different ways within sessions, from song discussion to instrumental re-creation to song transformation. Yet in the music therapy literature there is little to no research about the role of song analysis prior to using a piece in a session. There is research about analysis of lyrics written by clients in individual and group music therapy, and there is research about lyric analysis interventions and techniques used within sessions. However, these focus on in-the-moment or post-session analysis rather than song analysis as a way for the therapist to prepare for a session.This thesis will fill this hole in the music therapy literature. It is interdisciplinary in nature, as it examines methods of analysis found in music theory and musicology and applies them to music therapy work. There are three main sections of this thesis, each of which includes a literature review. The first focuses on establishing a common language of analysis for music therapists—that is, identifying categories of musical features that music therapists can make note of when they first listen to a song. The second section concentrates on persona theory, which comes from music theory. The last is centered on music and disability studies, which examines ideas from disability studies through the lens of musicology. Each section also contains a song analysis using the concepts explored in the literature review. Throughout the literature reviews and song analyses, I discuss how an understanding of the theories can benefit music therapists. I conclusion by proposing pedagogical and research implications of this thesis.

Multi-Integrated Segmentation Approaches for Permafrost Lakes Observed in Satellite Images College of Arts and Sciences: Physics Poster - Graduate Research

STUDENTS Ming Gong ADVISORS Ivan A Sudakov, K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 During the summer melt season, permafrost lakes in the Arctic display a complex geometry. Casual inspection of remote sensing images shows that the lake phase of Arctic landscape undergoes a transition where disconnected lakes evolve into much larger scale connected networks with complex boundaries. Spatiotemporal dynamics of lakes is crucial for the stability of the Arctic climate system. To understand how these features evolve over time, we propose to develop two integrated machine learning image segmentation techniques for lake pattern recognition. Classical machine learning methodologies for image segmentation require handcrafted features that are similar to our visual perception and simple classification strategies to provide accurate boundaries. Conversely, deep neural networks for image segmentation learn these features through different variations of gradient descent to create these boundaries as well. The specific objectives of this research are to implement a classical image segmentation architecture and a deep convolutional encoder-decoder architecture called SegNet and apply each architecture to Landsat satellite imagery obtained from Google Earth Engine in 2016. The study area covers Siberia (both Western and Eastern), Chukotka and Alaska. We compare deep learning segmentation with classical segmentation methodologies for segmenting permafrost lakes to determine the capabilities of each methodology and their effectiveness for lake segmentation in a variety of Landsat imageries.

Computational Modeling of Spin Dynamics College of Arts and Sciences: Physics Poster - Course Project, 201910 PHY 470 01

STUDENTS Kyle Thomas Hagan, Ivan A Sudakov ADVISORS Ivan A Sudakov LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The Ising model, originally developed in the 1920’s to analyse ferromagnetic properties has since found a myriad of other seemingly unrelated applications. An updated Ising model, Glauber’s spin dynamics, is used to examine phase changes in ferromagnetic materials and other systems. In the Glauber spin model, a system starts with some initial condition and over time the state of the undergoes small fluctuations that increase as more energy is put into the system. Then, there is a critical point where the system loses its initial condition and changes phase. Glauber’s spin model has been used to examine the changes that melt ponds in the arctic undergo over time. The model has been used in chemistry to determine whether polymer chains will form. Glauber’s model has even found uses in information theory. The goal of this project is to create an Ising model using Python then display some of the properties of the Ising model with a feedback mechanism coupling Glauber's spin dynamics and the external forcing on the system. The one dimensional and two dimensional Ising models are examined. It is shown, as Ising did, that the one dimensional model does not predict any phase changes. It is also shown that the Glauber spin model does predict phase changes for a system.

Many macroscopic (like lakes) and microscopic (like macromolecules) physical systems exhibit so-called nucleation phenomena, â&#x20AC;&#x153;collective growthâ&#x20AC;? of patterns in the system. Nucleation could be illustrated as infinitesimal seeds of the stable phase from inside the unstable phase. The process of phase transitions, including continuous (second order) or discontinuous (first order), forms the nucleation. Moreover, the fact that the kinetics when the temperature is quenched from above to below the critical temperature is observed in continuous phase transitions. In reality, the formation of clouds, fog, rain, smoke from burning, ice crystals in the refrigerator, bubbles from soda and beer, etc. are all representatives of nucleation phenomena. Thus, nucleation is applicable everywhere from chemistry to climate science.The objectives of this work are to model nucleation and growth by applying Kolmogorov-Avrami-Johnson-Mehl (KAJM) equation based on the probability equation and to implement a computation algorithm to describe pattern growth.

Modeling Chaotic Population Dynamics with Feedbacks College of Arts and Sciences: Physics Poster - Course Project, 201910 PHY 570 01

STUDENTS Christina Farwick ADVISORS Ivan A Sudakov LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 While generating a model for a particular system typically relies on the ability to predict the behavior of the system at some arbitrary time, deterministic chaos measures the diversion from predictability: more chaotic implies more disorder, less chaotic implies more predictable. This work will employ Lotka-Volterra equations to describe the dynamics of biological systems. The bifurcation point is the point at which the system goes from stable to unstable. Thus, the objective of this project is to modify the existing Lotka-Volterra model and create bifurcation diagrams. Previous work shows that population dynamics depend heavily on feedback with the environment. Feedback will therefore be introduced as a new variable, and it is expected that the updated model will be able to describe chaotic-dynamics with feedback included.

Fabrication of periodic poled lithium niobate for three-wave mixing College of Arts and Sciences: Physics Poster - Independent Research

STUDENTS Christy Elise Scott ADVISORS Imad Agha, Jay Mathews LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Lithium niobate (LiNbO3, LN) is a ferroelectric crystal used as a generation medium via nonlinear optical conversions. By periodically poling LN (PPLN) nonlinearities are enhanced for select wavelengths. This is due to the longer interaction length of the crystals in PPLN, instead of sub-mm it increases to a few cm, which produces a crystal with a high degree of effective nonlinearity. Poling LN causes a localized reversal in the direction of the permanent polarization of the crystal (i.e. domain reversal). In this work, we report our efforts towards the development of PPLN using photolithography and applying the bias voltage in a conductive aqueous solution. Ultra-high biased voltages show great promise for fabricating PPLN. The ultimate goal of this work is to use PPLN crystals for three-wave mixing and terahertz (THz) generation.

Changes in the Piezoelectric Response of Reactive Magnetron Sputtered Aluminum Nitride at Different Sputter Powers College of Arts and Sciences: Physics Poster - Honors Thesis

STUDENTS Rachel L Adams ADVISORS Said Elhamri LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Aluminum nitride (AlN) is a low-loss piezoelectric material that is commonly used in surface acoustic wave and bulk acoustic wave-based filters for radio frequency communication applications. For this material to be incorporated into devices, a more thorough understanding of the effects of different deposition parameters on the crystallinity and piezoelectric coefficient is needed. In this study, all the AlN films were deposited using reactive controllably unbalanced magnetron sputtering onto (0001)-orientated sapphire substrates. X-ray diffraction was used to characterize the crystallinity and atomic force microscopy was used to investigate the surface morphology of the films. Piezoelectric force microscopy was done to measure the piezoelectric coefficient of the films. The effects of changing the sputter power during the deposition on the crystallinity, surface morphology and piezoelectric coefficient will be presented.

STUDENTS Logan Edward Cordonnier ADVISORS Said Elhamri LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The goal of this project was to compare the quality of the Ga-free superlattices, InAs/InAsSb, to those of the Ga-containing structures, InAs/GaSb, for possible use as mid-infrared detectors. By using a 532 nm laser, two experiments were conducted. In one experiment, the temperature was fixed at 5 K and the laser power was varied between 10 and 2000 mW. In the other experiment, the laser power was fixed and the sample temperature was varied. The data was analyzed to determine various material parameters. The values of these parameters provided valuable information about the quality and the differences between these two structures. Based on the results of this type of sample characterization, it was clear that the Ga-containing superlattices outperformed the Ga-free ones.

Effectiveness of Political Campaigns: Richard Cordray for Governor of Ohio College of Arts and Sciences: Political Science Oral Presentation - Course Project, 201880 POL 310 01 STUDENTS Sarah Anne Kessel, Monique M Villanueva ADVISORS Christopher J Devine LOCATION, TIME Kennedy Union 312, 10:40-11:00 The purpose of this study is to evaluate the effectiveness of political campaigns in determining the outcome of an election. Past research strived to answer if the candidates’ campaign strategy caused the results, or if specific factors outside of the candidates control, known as “fundamentals”, predetermine the result? In order to answer this question, we examined Richard Cordray’s campaign for governor. We did this by first resolving his campaign strategy and then analyzing our exit poll data and the outcome of the election in light of his strategy. Our analysis, focusing on Cordray’s strategy of mobilizing his base around healthcare and persuading the working class, found that his campaign for governor did not have a significant impact on the results. Instead, we conclude that in this particular election the “fundamentals” overshadowed the campaign strategy. Although in our case study we determined the campaign did not matter, it is important to note that whether or not political campaigns matter in election results varies depending on the strength of the candidate’s campaign to alter the “fundamentals” that may be working against them.

Interracial Relationships and the Silver Screen: Guess Who’s Coming to Dinner (1967) and Get Out (2017) College of Arts and Sciences: Political Science Oral Presentation - Course Project, 201880 POL 381 01

STUDENTS Sarah Rose Daligga, Delali Benjamin Yao Nenonene, Cierra Dei Stewart, Maggie Mary Ward, Emma Joelle White ADVISORS Michelle C Pautz LOCATION, TIME Kennedy Union 312, 11:00-11:20 American film has long reflected the culture it was created in. Further, a film’s message, context, and relevance can impact audiences; movies make people happy, movies move people to action, movies inspire, and movies can inform. But most importantly, movies can influence how people feel or think about a topic. This influence that films can exercise over their audiences is what our group has examined. Specifically, we wanted to study the effect that movies about interracial relationships have on perceptions of interracial dating and marriage. In order to do this, we looked into how two particular cinematic pieces may influence the way an audience thinks about interracial relationships. How might the movies, “Guess Who’s Coming to Dinner” (1967) and “Get Out” (2017) influence or change audience’s perceptions about interracial relationships, particularly relationships between one black individual and one white individual? Our group aims to discover if films that star interracial couples change the way an audience perceives interracial relationships in current dating trends.

During the visit, patients are able to seek care from a provider and in addition, receive laboratory or radiographic services, if available at their free clinic (Darnell, 2010). However, free clinics often face a challenge in finding long-standing funds to support their cause. The National Association of Free and Charitable Clinics has reported an overall 20% decrease in clinic funding (Birs, 2016). Reach Out of Montgomery County, a free clinic in Dayton, Ohio, experienced a fund loss that left a 21% decrease in their typical budget (2017 Annual Report). Their funding partnerships with Montgomery County Human Service Levy (HSL) and United Way (UW) of Greater Dayton Area were terminated, due to change of direction towards a UW national theme in poverty (2017 Annual Report). In addition to Reach Out, a free clinic in Florida reports experiencing a budget cut as their clinic lost a 3-year grant that would have provided $100,000 in funding (Fantozzi, 2015). The clinics’ cessation of monetary support thus results in a tighter budget they are forced to operate on, which can cause added pressure to fulfill the needs of the underinsured. This poster will highlight the loss of funding free clinics are experiencing with a special focus on Reach Out of Montgomery County.

Stress and Olfaction: The Affective Link College of Arts and Sciences: Psychology Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Sahar Kaouk ADVISORS Julie Walsh Messinger LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Objectives:Odor presence may change the way a visual stimulus is perceived, and emotional state can influence olfaction, or the sense of smell (Zald & Parado,1997; Seubert et. al,2009; Pollatos et. al,2007). Under a negative emotional state, both males and females had decreased olfactory detection sensitivity but only males rated odors as being more unpleasant and intense (Chen & Dalton,2005). No study has examined sex differences in the effects of social and non-social stress on affective state and olfactory functioning. Females experience greater negative affect in response to social stress compared to males, who appear have distress following achievement stress (Stroud et. al,2002). In this project, sex differences in the impact of social stress and achievement stress on affective state and olfactory function will be investigated.Methods:Participants (N=128) will be randomly assigned to either: social or achievement stress condition. All participants will undergo baseline testing of odor detection sensitivity, hedonics, and intensity, then complete a battery of self-report questionnaires assessing affect, rejection sensitivity, and self-esteem. Participants in the social stress condition will undergo one round of Cyberball and participants in the achievement stress condition will take a difficult arithmetic test. Immediately after stress exposure, repeat olfactory testing and battery of questionnaires assessing affect and perceived stress will be administered. Significance:This project will expand the understanding of how affect and olfaction are related, and how sex influences these relations specifically how stress conditions induce negative affect and alter olfactory functioning. Since social impairment is present across a number of psychiatric disorders and olfaction is related to social functioning, understanding the impact of social versus non-social stress on affective state and olfactory function advancements in prevention and treatment of psychiatric disorders can be achieved. Differences between sex regarding olfactory functioning, emotional regulation, and reactions to stress

Narratives of Lost Meaningfulness: When Contamination Sequences have Humanistic Themes College of Arts and Sciences: Psychology Poster - Graduate Research

COLLEGE OF ARTS & SCIENCES

Goal 3: Good Health and Well-Being STUDENTS Joe Edward DeBrosse ADVISORS John J Bauer LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Life stories' affective sequences indicate how people feel about the changes in their lives. Contamination is a common affective sequence in which the narrative begins with positive or neutral affect but declines to negative affect. While previous studies showed that contamination sequences predict a variety of poor well-being indices (e.g., McAdams, Reynolds, Lewis, Patten, & Bowman, 2001), whether contamination's accompanying themes—such as humanistic or materialistic concerns—change their predictive utility for well-being is unknown. Based on the low- and turning-point narratives of 211 participants, we examined whether contamination sequences with humanistic themes (e.g., a loss of meaning due to unemployment) differed in their relations to well-being compared to contaminated narratives without humanistic themes (e.g., a loss of prestige due to unemployment). We predicted that contamination sequences would interact with humanistic themes to predict significantly lower levels of well-being. Though the data showed a trend toward this interaction, contaminated humanistic narratives were exceptionally rare and the interaction was not statistically significant.In addition, we refined the standard measure of contamination sequences into three categories, finding that contamination sequences only predict well-being when they begin with positive, not neutral, affect. A third, new category, bad-to-worse contamination, predicted the lowest levels of well-being.

The Effect of the Norm of Group Interest in Response to Leader Dissent College of Arts and Sciences: Psychology Poster - Graduate Research

STUDENTS Brandon Lawrence Porter ADVISORS R Matthew Montoya LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 I examine the influence of a leader's dissenting behavior in an intergroup task on a group member's evaluation of the leader's performance. In the proposed study, group members will participate in a Prisoner's Dilemma Game (PDG). False feedback will create a cooperative group decision and then group members will be informed of the leader's decision to conform to or dissent from the group's decision. The leader's decision will be paired with a high payout or low payout group outcome. I investigate predictions based on Social Identity Theory (SIT), Realistic Group Conflict Theory (RGCT), and Norm of Group Interest (NGI). NGI predicts individual variations in outcome-based evaluations of the leader, RGCT predicts high payouts should be associated with high evaluations of the leader. Lastly, SIT predicts a leader's dissent should result in lower evaluations of the leader from low identifying members regardless of outcome. Results will highlight each models' fit to dissent and leadership situations within an intergroup context.

Social Experiences and Smell

College of Arts and Sciences: Psychology Poster - Independent Research

STUDENTS Brooke Lois Lipnos ADVISORS Julie Walsh Messinger LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Background: Autism spectrum disorder (ASD) is associated with olfactory impairments (Suzuki et al., 2003) and high rates of social dysfunction (Hadijikhani et al., 2005). Research suggests that there is a relationship between olfactory impairments and socail dysfunction in autism (Thye et al., 2018). However, the relation between olfaction and social function in a normative adult population has yet to be studied. This two-part study aims to address this gap by investigating relations between olfaction and social function in undergraduate students. Methods: 200 participants will complete eight questionnaires about their social preferences, experiences, feeling of socail experiences and importance of smell. Additionally, participants will undergo testing of odor detection sensitivity, identification, and hedonic response to odor and complete two tasks that access decision making and social navigation. It is hypothesized that odor identification scores will be positively correlated with social function and that females will outperform their male counterparts in both olfactory and social navigation tasks.

Maternal parenting was assessed whenchildren were between 3 and 5 years of age using a combination of an interview andobserver ratings. Maternal depression showed a trend level association with decreasedresponsiveness (Beta = -.16, p = .076), and showed a significant association withincreased harsh parenting (Beta = .15, p = .047) and decreased learning stimulation(Beta = -.14, p = .002). Fussy temperament did not moderate associations betweenmaternal depression and parenting. These findings suggest that maternal depression is arisk factor for parenting characteristics that are associated with negative childoutcomes, but that difficult temperament does not affect these associations.

Examining the Impact of Narcissism and Academic Exaggeration on Academic Performance of Undergraduate Students College of Arts and Sciences: Psychology Poster - Independent Research

Goal 3: Good Health and Well-Being Goal 11: Sustainable Cities and Communities STUDENTS Matthew Richard Faherty, Lindsay Maria Koeller, Josh David Pasek, Megan Elizabeth White ADVISORS Erin Marie O'Mara LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Over the last several decades, researchers have found evidence that narcissism is increasing generationally such that older generations were less narcissistic when in college than college students are today. Narcissism consist of recurring patterns of grandiosity, constant need for admiration, and lack of empathy towards others. Students high in narcissism and egocentric self-views are have higher expectations of their academic performance in college, but these expectations may not necessarily correlate to actual academic performance. Previous research found that undergraduate students tend to exaggerate or inflate their grade point average (GPA). The current research examines the association between narcissism and academic exaggeration (reporting a higher GPA than their actual GPA), and subsequent academic performance. The current, longitudinal study recorded participantsâ&#x20AC;&#x2122; self-reported GPA and their official GPA at the start and end of the semester they participated in the study, as well as multiple measures of narcissism. It is predicted that the association between academic exaggeration and subsequent GPA will vary by narcissism, such that students with higher levels of narcissism who exaggerate their academic performance will have a lower subsequent GPA.

Sleeping on "it" DOES work: Memory for pictures becomes stronger the day after learning, even with an interruption in the learning task College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education

STUDENTS Victoria Lynne Karpuszka, Sarah Phoebe Lawson, Madeline Margaret Nash, Alicia Michelle Selvey, Gabriella Louise Silone, Carolina Sofia Vazquez ADVISORS Susan T Davis LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Research indicates that memories are strengthened by consolidation, the incorporation during sleep into a previously established memory network (Rasch & Born, 2008; 2013). Memories are initially unstable after encoding and sleep consolidation increases resistance to interference (Robertson, 2011). On the first day of a two-day experiment designed to examine whether an encoding task interruption and a delay in retrieval would affect later memory consolidation, participants memorized pictures of common objects (e.g., owl) presented in a slideshow. Participants were assigned to complete either an immediate recognition test that included studied and unstudied pictures (“lures”), or return the following day to complete a delayed recognition test. Some were assigned to be tested on the two consecutive days. There were three hypotheses: (a) target pictures tested for memory only on the second day would be remembered as good if not better, due to sleep consolidation, than when tested for memory only on the first day; (b) there would be serial position effects on sleep consolidation of the target pictures due to the task interruption, such that recency before interruption would be reduced while other serial position effects would be stable; (c) pictures tested on both days would be better remembered on the second day than on the first. A 3 (Test day: Day 1, Day 2 or both days) x 2 (Test stimulus: Targets and Lures) ANOVA compared correct discrimination for each condition. The interaction between stimuli and testing day was significant and strong (p = .001, η2 = .189), indicating that participants tested on Day 2 were as correct as those on Day 1 in identifying picture targets. However, although participants on Day 2 remembered more targets, they also incorrectly remembered more lures than on Day 1. Sleep consolidation has an overall effect of maintaining the strength of “real” memories over time.

research utilized different types of indirect questions to better determine if someone is being deceptive. These questions were based on the role of biases, individual personality characteristics, and expected behaviors,-verbal and nonverbal-, all believed to be associated with deception. Answers from a control group of observers asked direct questions about whether an interviewee in a video was lying about previous behavior were compared with answers from an experimental group of observers asked indirect questions. Two research hypotheses about the outcome of this manipulation are: (a) indirect questioning of an interviewee’s dishonest responses would produce more accurate determinations of dishonesty than direct questioning, and (b) questions designed to detect bias about or expectations of dishonest behavior would be more accurately related to the dishonesty of the interviewee in the video than those questions related to interviewee verbal and nonverbal characteristics. Data collected thus far indicate that indirect questions, as a group, are consistently better at detecting deception. The next steps in our analyses are, first, to analyze the different types of indirect questions (biases, characteristics, and expected behavior) to better understand which indirect questions are more reliable in detecting deception, and second, to assess any interactive effect of participants’ gender with the gender of the interviewee in the videos on detection results.

Impact of Parental Involvement in the use of Adaptive eBook Technology on Preschoolers' Math Skills College of Arts and Sciences: Psychology Poster - Independent Research Goal 4: Quality Education Goal 10: Reduced Inequalities STUDENTS Patrick Caleb Ehrman ADVISORS Mary Fuhs LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 By the time students in the United States reach the fourth grade, the majority do not perform at or above the level of proficiency in mathematics (National Assessment of Educational Progress, 2017). A child’s education in mathematics begins at a very young age. One method by which children are introduced to the basic concepts of math is number books. Traditional number books have been found to be successful in promoting mathematical knowledge, but are stagnant in their difficulty, leaving parents to discern ambiguously when their child is ready to move onto more difficult problem-solving (Elia, Heuvel-Panhuizen & Georgiou, 2010). The present study seeks to discern the effectiveness of new eBook technology, as well as the impact parents have on their children's ability to learn. Specifically, does a discrepancy in the magnitude of the pictures in counting books lead to better learning and does the eBook facilitate learning that overcomes a parent’s anxieties in math. Two different eBooks will be read to thirty randomly selected parent-child pairs at the Dayton Metro Library during their summer Family Story Time sessions. Children will be ages 3-5. A survey will be used post reading to measure the parents’ predisposition towards liking or disliking math, as well as their current methods of math instruction in the home. The results of this study will be assessed using a paired samples t-test. This study predicts that the eBook containing discrepancies in image magnitude will facilitate higher quantity and quality of math-based discourse between parent and child. Additionally, the eBook formatting will help combat the impact a parent’s math anxiety has on their child.

Smelling How to Feel: The Impact of Odor on Affective Evaluation and Mood College of Arts and Sciences: Psychology Poster - Graduate Research

STUDENTS Michael Alexander Lee ADVISORS Julie Walsh Messinger LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Olfaction, or the sense of smell, and emotion have long been recognized as closely related. Previous research has found that odors are not only capable of influencing our mood, but can also affect the way we evaluate different types stimuli that are associated with them. However, no study to date has examined how odors can influence the way we evaluate visual stimuli, nor considered the relationship between odor’s ability to influence mood as well as affective evaluation. This study seeks to address this gap in the literature. For this study, we have participants complete questionnaires about their demographic information, current mood, and the affective impact of odor for them. Then, we have them view a series of images and rate them for positive valence, negative valence, and intensity. Once they have viewed all the images, participants then relocate to another room that has been prepared with a pleasant odor, unpleasant odor, or no odor. The participants then complete another questionnaire regarding their mood following odor exposure, and they then view and rate another set of images, which contains both new images and the same images they viewed earlier. We hypothesize that participant’s reported mood state will change after being exposed to a pleasant or unpleasant odor, that their ratings of positive and negative valence for the images will change after being exposed to a pleasant or unpleasant odor, and that the change in image ratings is mediated by their change in mood due to the odor. Furthermore, due to there being a number of known sex differences in olfaction, we hypothesize that any odor’s effect on mood and image ratings will be more pronounced for female participants. This project is ongoing and we plan to have final results by Summer 2019.

Comparison Analysis

College of Arts and Sciences: Psychology Poster - Graduate Research

STUDENTS Kirsten Lee Anderson ADVISORS Jackson A Goodnight LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The use of corporal punishment (CP) as a disciplinary strategy is a highly controversial topic among the scientific community and general public alike (Gershoff, 2013). Although there is extensive research examining the outcomes associated with the use of CP, limitations in methodology have made it difficult for researchers to make definitive claims about the outcomes of CP (Baumrind, Larzelere, & Cowan, 2002; Ferguson, 2013; Larzelere & Kuhn, 2005). For example, past studies have not examined the outcomes of CP within the context of individual differences among children. The purpose of this study was to understand if temperament, that is, early appearing, stable individual differences in reactivity and self-regulation (Rothbart & Bates, 1998) moderates the outcomes of CP. Specifically, we sought to answer the following questions: (1) do children who receive CP exhibit higher levels of internalizing and externalizing problem behaviors compared to children who do not receive CP? (2) among children who receive CP, do children with difficult temperaments show greater increases in internalizing and externalizing behavior problems compared to children with moderate temperaments? Analyses were conducted using multilevel growth curve modeling in order to compare siblings who have different disciplinary histories and temperaments while accommodating non-independence of data points. The results and implications of this study are discussed.

self-views discriminate towards racial minorities in subtle, rationalizable ways (Gaertner & Dovidio, 2000). Unlike overt, intentional racism, aversive racism is characterized by feelings of uneasiness about racial minorities rather than hate and hostility; however, it still results in discrimination towards racial minorities. Research examining white people’s attitudes and behavior towards black people finds that one context in which aversive racism occurs is when discrimination towards black people can be blamed on non-racial factors. That is, people fail to identify race playing a role in why they behaved more positively towards other white people than they did black people. The present study seeks to examine the prevalence of aversive racism in the reality-television series, Survivor, where contestants vote someone out of the game each week in order to win a one-million dollar prize. With few exceptions, the majority of contestants each season are white, and attribute their decision of who to vote out of the game to various non-racial factors. We will examine the association between contestant race and the rate at which they are voted off the show by the other contestants. Aversive racism predicts that, although there are usually far fewer nonwhite contestants each season, non-white contestants would be voted-off at a disproportionately higher rate than the white contestants.

Associations between Normative and Pathological Personality Traits and Hedonic Judgment of Odor Vary by Sex College of Arts and Sciences: Psychology Poster - Independent Research

STUDENTS Sahar Kaouk, Michael Alexander Lee, Brooke Lois Lipnos ADVISORS Julie Walsh Messinger LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Background and Purpose:Normative personality traits (Larsson et al., 2000; Pause et al., 1998; Shepherd et al., 2017) and sex (Brand & Millot, 2010) appear to be related to odor detection sensitivity, identification, and hedonic judgment. However, sex differences in associations between olfaction and normative and pathological personality traits have not yet been studied. The aim of the present study was to investigate whether associations between select normative and pathological personality traits and olfactory function vary by sex. Subjects:134 University students (Male N=63; Female N=71) participated in the study for course credit. Materials and Methods:Participants completed the PID-5 (Kruger et al., 2012) and the NEO-PI-3 (Costa & McCrae, 2010). Odor detection sensitivity, identification, and hedonic response (pleasantness and unpleasantness) were assessed using Sniffin’ Sticks (Hummel et al., 1997). Multiple linear regression analyses were performed separately for each measure, and stratified by sex, to examine associates between eight NEO-PI-3 and eight PID-5 facets hypothesized to be related to olfaction. Results:Regarding NEO-PI-3 facets in females, Depression (β=.431, p=.010) and Fantasy (β=-.341, p=.024) predicted odor pleasantness ratings while vulnerability predicted odor identification (β=-.477, p=.002); in males, olfaction was not related to any NEO-PI-3 facets. For the PID-5 facets, Restricted Affectivity predicted odor pleasantness ratings in males (β=-.366, p=.037), whereas in females, Depressivity (β=.454, p=.005) predicted odor pleasantness ratings. In males, Anhedonia (β=-.737, p=.004), Depressivity (β=.672, p=.006), Restricted Affectivity (β=.542, p=.001) and Suspiciousness (β=.302, p=.047) predicted odor unpleasantness ratings, while Anhedonia (β=.443, p=.013) and Depressivity (β=-.397, p=.015) predicted odor unpleasantness ratings in females. Conclusions:Most notably, associations between odor unpleasantness ratings and PID-5 anhedonia and depression differed by sex; less anhedonia and more depression predicted higher odor unpleasantness in males while the converse was found in females. Implications of these findings on personality assessment research will be discussed.

Shame on Me? Examining Impression Management and Appearance-Related Shame Across the Menstrual Cycle College of Arts and Sciences: Psychology Poster - Independent Research

STUDENTS Nicole Beasley, Kala Marie Jablonski, Fiona Mairin O'Malley ADVISORS Erin Marie O'Mara LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Impression management occurs most often in social interactions in which a person regulates and controls the information they share, usually to present themselves in a positive manner. The desire to make a positive impression on other people can impact the type of information a person shares with others as well as the amount of effort one puts into their physical appearance. Previous research finds that, at peak fertility, women tend to put more effort into their physical appearance than when they are at low fertility, at least in part, to appear more attractive to potential mates. However, failing to appear physically attractive or not trying to make a positive impression on potential mates by looking your best may lead to feelings of shame about one’s efforts at making a positive impression on others. The present research examines the association between fertility and appearance-related shame, and whether that association varies by impression management. It is predicted that women with higher levels of impression management will experience higher appearance-related shame at peak fertility than women lower in impression management.

Religiosity and Political Participation College of Arts and Sciences: Psychology Poster - Independent Research

COLLEGE OF ARTS & SCIENCES

STUDENTS George Joseph Bommer, Claudia Nicole Dominique, Bea Mercedes Santos ADVISORS Erin Marie O'Mara LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Religiosity can be described as the extent to which an individual is committed to their values, beliefs, and practices of, or related to, their faith. A person’s religiosity can impact many aspects of daily life, including their identity and attitudes towards politics. The relationship between religion and politics has been the focus of much research, with many studies examining the relationship between religiosity and political affiliation, or the political party with which a person most identifies. Data from the 2018 midterm elections (Pew, 2018) found that the candidate a person voted for was largely influenced by their religious affiliation, such that more religious people, in general, were more likely to vote for Republican candidates while less religious people were more likely to vote for Democratic candidates. Recently, however, studies have shifted their attention to the association between religiosity and politically-related civic engagement. While previous research finds that religiosity impacts who a person votes for, it does not speak to whether voting in elections, in general, differs by a person's religiosity. The current research seeks to contribute to this line of research by focusing on the extent to which an individual’s religiosity is associated with their political behavior, specifically whether they register to vote and whether they vote (if eligible and registered).

Intelligence and Interpersonal Functioning in Youth and Young Adults with Varying Levels of Psychopathic and Callous-Unemotional Traits College of Arts and Sciences: Psychology Poster - Honors Thesis

STUDENTS Marie Hermine Feyche ADVISORS Jackson A Goodnight, Tina Dilem Wall Myers LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The current study examined 30 youth and young adults ages 12-21 who were receiving therapy services at South Community, Inc. The intelligence and interpersonal functioning of individuals with varying levels of psychopathic and callous-unemotional (CU) traits was studied. Although there are a variety of conceptualizations of psychopathy, this study used the Triarchic Model of Psychopathy (TriPM), which defines the three factors of psychopathy as boldness, meanness, and disinhibition. CU traits are a downward extension of psychopathy, overlapping with the meanness factor, and are embodied by an absence of guilt, remorse, and the expression of superficial emotion. “Successful” psychopathy is a term applied to individuals who have psychopathic traits but are non-antisocial and function at a comparable level to individuals lacking psychopathic traits. Interpersonal functioning refers to one’s ability to interact with others; a significant distinction between successful and unsuccessful psychopathy involves interpersonal skills. Both verbal and abstract intelligence were assessed. Participants completed the Triarchic Personality Measure (TriPM), the Inventory of Callous-Unemotional Traits (ICU), the Interpersonal Reactivity Index (IRI), and the Shipley Institute of Living Scale-Second Edition (Shipley-2) in order to assess their levels of psychopathy, CU traits, interpersonal functioning, and intelligence. It was hypothesized that individuals with high levels of CU traits, psychopathy, and intelligence would have higher levels of interpersonal functioning than individuals with high levels of CU traits and psychopathy but low levels of intelligence. It was also hypothesized that this relation will be particularly true for abstract intelligence. This is supported by previous research suggesting low intelligence is present in psychopathic individuals who exhibit antisocial and violent behavior and may correlate with the predisposition to callous-unemotional behavior in youth.

Pretrial Publicity and Juror Decision-Making: Effects of Inadmissible Confession Evidence and Coverage of Its Exclusion from Trial College of Arts and Sciences: Psychology Poster - Honors Thesis

194

COLLEGE OF ARTS & SCIENCES STUDENTS Rebecca S Rhein ADVISORS Dario Norman Rodriguez LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The courts have long been concerned that exposure to media coverage regarding a case making its way through the judicial process (i.e., pretrial publicity [PTP]) may influence jurors’ decision-making in court. Indeed, empirical research over the past two decades has shown that PTP can influence juror decisions. PTP often contains descriptions of evidence or factors that are ultimately deemed inadmissible at trial (e.g., confession evidence), but no research to date has examined what occurs when confessions are reported to the public but later deemed inadmissible. We examined these issues using a 2 (Interrogation Quality: High vs. Low) x3 (Exclusion: Technicality vs. Cause vs. Not Specified) +1 (No Confession PTP Control) +1 (No PTP Control) mock juror experiment. Undergraduate students were randomly assigned to read various forms of pretrial publicity. In a second session conducted two days later, participants read a trial transcript that omitted any mention of the critical evidence contained in some versions of the PTP. Participants evaluated the evidence and rendered a verdict. Participants who were exposed to pretrial publicity were nonsignificantly more likely to find the defendant not guilty than those who received no pretrial publicity. When participants were not told the reason for the exclusion of the confession, they were more likely to convict the defendant. This may reflect a tendency of jurors to fail to disregard inadmissible evidence unless convinced of a rationale for its exclusion.

The Melody of Spatial Memory

College of Arts and Sciences: Psychology Poster - Honors Thesis

STUDENTS Victoria Lynne Karpuszka ADVISORS Susan T Davis LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Music has been studied extensively in psychology, including research on musically-induced emotion. However, the project reported here looked at new effects of musically-induced emotions on spatial memory. Palmiero and colleagues (2016) established that music and emotions are associated. Music of a major mode, or an Ionian mode, is usually associated with positive emotions. Music of minor modes, such the Locrian or Aoelian modes, are associated with negative emotions. These associations with the specific modes are seen by the lowering of the third and sixth scale tones. Participants for the present study completed a spatial memory task (called the “Tower of Hanoi”) while listening to music of different valences (found in previous research to create feelings of positive and negative emotions). Participants completed the task both with and without music playing. Following completion of the tasks, participants reported on emotional state using the Positive and Negative Affect Scale (PANAS; Watson, Clark, & Tellegen, 1988). I hypothesized that those who listened to the positive-valanced music while completing the spatial task would perform better (i.e., faster) than those who listened to the negative-valanced music. Preliminary results indicate this to be true. In addition, participants exposed to negative-valenced music were less likely than those participants exposed to positive-valenced music to complete the spatial memory task in the required amount of time. Participants generally reported a mood score on the PANAS that decreased, regardless of the induced mood (positive- or negative-valenced) after working on the spatial memory task. This result appears to be related to the inability to complete the task or the length of time needed to complete the task.

The Power of Hashtags: The Praxis of Solidarity in the Digital Sphere College of Arts and Sciences: Religious Studies Oral Presentation - Graduate Research

STUDENTS Jens Mueller ADVISORS Vincent J Miller LOCATION, TIME Kennedy Union 311, 9:20-9:40 Recently established social movements such as #MeToo or #TimesUp use the social media platform Twitter in a very distinct way than other movements did in the past. While former movements used Twitter as a tool to organize and mobilize social activists, #MeToo and #TimesUp use it in a formative way by creating emotions and a sense of togetherness in the digital sphere. It enables activists to connect in very different ways with each other, crossing spatial boundaries and experience a new sense of unity through digital media. This project argues that the theological concept of solidarity can benefit from these examples in significant ways. As Pope John Paul II states in his encyclical Sollicitudo rei Socialis, “Solidarity is not a feeling of vague compassion or shallow distress at the misfortunes of so many people, both near and far. On the contrary, it is a firm and persevering determination to commit oneself to the common good; that is to say, to the good of all and of each individual, because we are all really responsible for all.” I propose that the use of Twitter aids in practicing solidarity in an effective way, demonstrating the transformative nature of social media for Catholic social thought. The examples of the #MeToo and #TimesUp movements help in underlining how people show their support through social media, extending the notion of solidarity from mere compassion towards working for the common good. Solidarity moves beyond the public sphere into the digital world and becomes a key element in promoting social justice. At the same time, this project highlights how Christians expand their outreach from local parishes to a global network of solidarity that is both public and digital.

College of Arts and Sciences: Religious Studies Oral Presentation - Graduate Research

STUDENTS Joshua Allen Wopata ADVISORS Dennis M Doyle LOCATION, TIME Kennedy Union 312, 9:20-9:40 Many American Catholic laity have been hungry for examples of lay saints, especially spouses and parents, that model holiness in the modern world. In recent years there has been a host of new American causes of laity that are either under investigation or on their way to the Vatican. While many Catholics are familiar with Dorothy Day, not as many are familiar with the many other recent causes of laity in process.This group consists mostly of “outsiders” to one version of the American story (former slaves, Native Americans, a Mormon, a disabled person). The sociological profile of this group is significant when we think of the canonization process as involving the contemporary American Catholics discerning which legacies are vital to demonstrating the Second Vatican Council’s universal call to holiness. This paper will briefly introduce the whole group but focus on one significant cohort of mystical women that had many remarkable similarities (mothers, converts, stigmatists), and who were active about the same time (1940s/50s).Using Charles Taylor’s analysis of key features of modernity and some hagiographical highlights, this paper will demonstrate that these holy persons emerge out of and sustain social imaginaries that serve as an attractive alternative to our secular age. For instance, this type of theological imagination seems to assist these holy persons in escaping an overly individualistic, nationalistic, and materialistic vision that western people are susceptible to. These exemplars also point us towards the way that the supernatural realities are not simply bound up in the Church or the sacraments, but overflow into our everyday lives if we allow them to. While very few people will ever experience mystical visions or the stigmata, these saints point to the more important reality that every aspect of our lives can become divinized on account of God’s Incarnation in Christ.

Oral Presentation - Capstone Project STUDENTS Rachel Patricia Favre ADVISORS Leslie H Picca LOCATION, TIME Kennedy Union 211, 9:00-9:20 The purpose of this study was to examine how well prepared student teachers feel to teach in diverse, urban settings. This study looked at how different student teaching programs impact how prepared one thinks they are to enter the diverse and urban field of education and teaching. Earlier research shows while teachers believe they are not impacted by the race and diversity of their students, many are hiding it through colorblindness. This study seeks to answer the question of â&#x20AC;&#x153;How well prepared do student teachers from a private, catholic university feel to teach in diverse, urban settings.â&#x20AC;? The goal for this study was to interview students from the Urban Teaching Program who are in the Early, Middle, High School, and Special Education Programs to see how prepared they feel to teach at diverse schools. Preliminary data suggests that student teachers believe they are prepared, yet they also think more can be taught on how to teach with diversity in mind.

Changes in Binge Drinking: A Cross-Generational Study

College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project

STUDENTS Mayra Arlet Baeza ADVISORS Jacqueline Marie Milling, Leslie H Picca LOCATION, TIME Kennedy Union 211, 9:40-10:00 The concept of binge drinking is not new, especially on college campuses. There have been numerous studies examining the causes and consequences of college binge drinking. Some explanations include the attitudes students have toward binge drinking, which tends to be a positive one where "college kids will be college kids." This is despite the negative, sometimes deadly, consequences to excessive drinking which impacts physical property, finances, physical health, mental well-being, academics, relationships, and the criminal justice system. There are multiple factors that impact why college students participate in binge drinking such as gender, race/ethnicity, peers & social groups, social media, and parents. This research examines how binge drinking has changed over the decades, particularly at the University of Dayton. Using snowball sampling, data were gathered by interviewing current UD students whose parents attended UD, as well as the alumni parents. The findings suggest that binge drinking is romanticized as a core element of college life.

Racial Disparities Unwilling to Die: Infant Mortality Rates in Ohio College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project

This research examines the impact of Centering Pregnancy (a group prenatal model used to decrease Infant Mortality and Infant Mortality Rates) among non-minority white babies and babies of color. Given the legacy of racial hierarchies and the physiological impact of living in a highly racialized society, women of color have worse health outcomes even before they become pregnant. The literature suggests group prenatal care can act as a model to

COLLEGE OF ARTS & SCIENCES

help decrease Infant Mortality Rates. Data from the Ohio Department Health Data Warehouse and the Centering Healthcare Institute was gathered to compare the number of births and number of infant deaths among non-minority white babies and babies of color in nine counties that comprise the Ohio Health Equity institute: Butler, Cuyahoga, Franklin, Hamilton, Lucas, Montgomery, Stark, and Summit. The results suggest that there is a relationship between Centering Pregnancy and a decrease in Infant Mortality rates; the counties that utilized Centering Pregnancy as a model correlated with increased infant vitality rates. As Centering Pregnancy has only been implemented in some of those counties over the past ten years, this research suggests that over time Centering Pregnancy could help decrease infant mortality rates.

In addition, this research looked at how the executive orders and policies implemented by the Trump Administration have impacted the refugee and immigrant population. Data were gathered using a qualitative research method consisting of interviews with refugees and immigrants who have lived in the Dayton area for at least five years. The results of this study found that language barriers, a lack of access to education, and discrimination in terms of employment and housing were primary challenges for the refugee and immigrant population. This study examines each of these issues in-depth, as well as delves into ways in which the city of Dayton can work on better assisting in the integration process.

This research examines STS in current Children Services workers who work directly with victims of child abuse or neglect. This research also looks at how frequently Children Services workers are exposed to opioid-related cases in their professional lives. Data for this project were gathered by administering a survey to two area Children Services agencies to assess the STS levels of those who work there. The results of this research show that there is a weak to moderate association between the frequency of a Children Services worker’s exposure to opioid-related Children Services cases and a higher level of STS.

Murky Waters: The examination of institutional racism in response to natural disasters College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project

STUDENTS Aaron Winfrey Olin Winfrey ADVISORS Leslie H Picca LOCATION, TIME Kennedy Union 211, 12:00-12:20 In the United States we have seen an increased frequency in the number of natural disasters which has produced additional intervention by agencies on each governmental level to combat economic problems and provide social services for those effected. Just as disasters have increased in magnitude and destruction, the cost to repair those damages have increased as well. Therefore, the likelihood of each region to support themselves in the future will decrease and government intervention will become an absolute necessity. As the occurrence of disasters increase so too will the need for administrative assistance by the U.S. government. They fund and maintain the infrastructure, they provide the majority of social services, and they assist with the reparation of victimized communities. Their totalitarian role in the process from start to finish makes it all the more important when understanding why certain communities are adversely effected more than others. This study is therefore important because of the role future administrations will have in providing services to future victims of natural disasters. For my research I will be comparing the federal government’s management of three particular disasters that have occurred within the last fifteen years and compare some of the differences in the way certain racial populations were affected while the disaster occurred. I will specifically be asking the question, “Did the federal government’s management of Hurricane Katrina, Maria, and Harvey reflect forms of institutional racism?” I will use this question to examine the relationship between vulnerable racial groups and victimization. The specific dimensions I am looking are include the differences between whites and minorities and the resources attributed compared to the damage of the storm. My hope is to highlight relationship between the responses of the Bush, Obama, and Trump administrations and the racial groups that were adversely effected by the three hurricanes.

Goal 16: Peace, Justice, and Strong Institutions STUDENTS Chloe Marie Kisela ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Crime, violence, and childhood trauma are all unfortunate things to speak of, yet they are ever-present in our society. We might have several questions about what factors have a casual influence on these events and how we can prevent them, but for the researcher, one question stood out among others â&#x20AC;&#x201C; could all three be connected in some way? In conjunction with that thought, this project uses secondary data analysis to examine whether or not childhood trauma (neglect, abuse, parental death, parental absence, etc.) is related to later adult criminal offending or violent behavior. In addition, specific psychological processes that could possibly connect childhood trauma with adult offending have been researched and described, including learned helplessness, classical conditioning, neurological changes in the brain post-trauma, and the emergence of psychological disorders. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) has been utilized through statistical analysis in pursuit of supporting or refuting the hypothesis, which believes that there is a positive relationship between childhood trauma and adult offending. This is all done with the motive to help reduce childhood trauma and adult offending and violence because, in order to pursue the weighty goals of putting an end to crime as well as childhood suffering, we must first work to better understand them and how they relate to each other.

Inside the Life of a Sex Offender; Utilizing Psychosexual Evaluations to Analyze the Background, Current State, and “Normalcy” Post-treatment College of Arts and Sciences: Sociology, Anthropology, and Social Work Oral Presentation - Capstone Project

STUDENTS Kelcey Lorraine Leeming, Pamela Rose Segalewitz, Maggie Margaret Yontz ADVISORS Martha Henderson Hurley LOCATION, TIME Kennedy Union 211, 4:00-4:20 Addiction is described as a compulsive need for and use of a substance. When we as a society think of someone’s addiction we tend to think of drugs or alcohol, but what we may not think of right away is that someone can have a compulsive need for sex. We analyzed sexual offenders to explore the factors associated with sex offenses and the factors that could lead a sex offender away from recidivating. After reviewing the factors associated with the offenses, we focus on treatment- what works and what does not. Ultimately, for our senior project we want to understand if sex offenders can live a “normal” life after treatment. In analyzing the case studies on sexual offenders we have enlisted the help of Dr. Ronald DeLong, a clinical psychologist with more than 35 years of experience working with sex offenders. Through a review of case files, analysis of treatment protocols, and in consultations with Dr. DeLong, we explore whether sex offenders can be reintegrated successfully back into society.

Students apply economic theory and econometric techniques to analyze data in order to answer an original research question.

Asset Size, Asset Growth, and Stock Returns; an Empirical Analysis, 2008-2017 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS John Martin Harmon ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In this study, I consider two important strategic investment issues: (1) firms size matters and (2) asset growth is a predictor of returns in the cross section. Empirically, I test two hypotheses: (1) Small firms outperform larger firms over long periods of time and (2) firms with the highest asset growth rates underperform firms with low asset growth rates over long periods of time.Both of the above hypotheses have been tested in previous academic studies but not for the period 2008-2017. This period includes a major economic and market recession in 2008 followed by a major market expansion continuing through 2017. With this bull market, however, market returns are uneven, with a flatter trading range year in 2011 and a down market year in 2015. As a result, I will also be able to see the effects of return variability on the asset size and asset growth portfolios.Following the approach taken by Eugene Fama and James Macbeth1, I compare the performance of large size firms to small size firms over the period 2008-2017. Using the 500 stocks included in the S&P 500 index as my sample universe. I develop portfolios of stocks based on asset size and use two investment strategies to make the performance comparisons: (1) Buy and Hold and (2) Rebalance (annually). To test the 2nd hypothesis, I follow the approach used by Michael Cooper et. al.2 and calculate asset growth rates for all S&P 500 stocks on a yearly basis from 2008-2017. Firms are sorted by asset growth rates, high to low, and placed in portfolios of 50 stocks each. The highest growth rate portfolio and the lowest growth rate portfolio returns are then compared on an annual and cumulative basis using buy and hold and portfolio rebalancing strategies. Return comparisons are also made against SPY, the S&P 500 SPDR ETF. Finally, using the information ratio, risk adjusted returns will be calculated for the asset size and growth portfolios to determine which portfolio models have the best risk-return outcomes.

stock (concentrated) Portfolios in the S&P 500 Healthcare sector (XLV). I compare the the returns for these concentrated portfolios to the returns for the S&P 500 Index, ETF SPY, and the SPDR Healthcare Sector ETF, XLV. My sector weights are sales growth and relative price change, and the period of analysis is 2009-2017. I test the hypothesis that a rules based portfolio of stocks will outperform a broad based passive index (SPY) and its sector counterpart (XLV).

In this study I develop a two factor weighting model for a concentrated portfolio of 10 and 20 stocks in the S&P500 Industrial Sector ETF XLI. I use sales growth and relative price change as my weighting factors and test two hypotheses (1) Concentrated stock portfolios with FBFW models can outperform the broad market over long periods of time and (2) Concentrated stock portfolios with FBFW models can outperform their market weighted sector counterparts over long periods of time. The period of analysis is 2009-2017.

A key variable in determining U.S. Federal Reserve Policy concerning Fed Funds Rates is the inflation rate in the U.S. economy. In this study, I developed time trend models for each month of the year using 2009 - 2017 as my modeling period. I then used the twelve time trend regression equations to forecast inflation levels for each month in 2018. Adjusting the forecast using the root mean square forecasting error procedure, I test for forecasting accuracy based on an error tolerance of 2%.

A comparison of Pre and Post 2008 inflation trends for the consumer Price Index (CPI) Less Food and Energy: An Empirical Analysis 1999â&#x20AC;&#x201C;2018 School of Business Administration: Economics and Finance Poster - Independent Research Goal 4: Quality Education STUDENTS Christian Gerard Hense ADVISORS Tony S Caporale, Robert D Dean LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Despite an aggressive policy of Monetary easing by the Federal Reserve. Inflation seems to be rather benign after the 2008 recession. In this study I compare inflation trends before and after the 2008 recession to determine if the long term inflation trend has significantly changed due to the 2008 economic rescission. I use the inflation metric CPI -Less Food and Energy because it is a measurable, less volatile measure of inflation. I also forecast CPI (LF&E) for 2018 using Linear Trend regressions adjusted for a root mean square error (RMSE). I use an error tolerance of 2% to determine forecasting accuracy.

The system will provide a fully operational approval system in which the different divisions and departments of MacB can each approve, update, and pass the purchase request to the next group. The purchase request begins when the requester fills out an electronic SharePoint form asking for supplies. This begins a long approval, justification, and pricing process. After price analysis, thepurchaser will begin receiving quotes from the bidding companies. The best bid will receive the contract. The product then ships, arrives, and undergoes a quality check. A final confirmation of a completed purchase is needed. MacB would like an implemented notification system where users are alerted alongthe process of a contract as it moves through the different stages.The purchasing report system will be created through Microsoft SharePoint.

A Call for Research on the Development of MDD with Psychotic Features

School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Christopher Patrick Courtney ADVISORS Meredith L T Montgomery LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In recent years, Major Depressive Disorder (MDD) is becoming more normalized especially as medication for it appears in commercials and other media on a regular basis. Psychotic symptoms, an often-misunderstood specifier for this disorder, are occurring more frequently while being discussed less often. These symptoms can manifest in many ways, including but not exclusive to paranoid delusions as well as auditory or visual hallucinations, and can be congruent or incongruent to the client’s mood. While at the current moment, medication is viewed as the primary treatment, other forms of psychosis-specific treatment are emerging and need to be studied more intently (e.g. Cognitive Behavioral Therapy). Existing research on the developmental path of MDD with psychotic features is not sufficient to inform these integrative treatment modalities. This poster presents the current literature on MDD and highlights areas for future study.

The Influence of Study Abroad on School Psychologist Cultural Competence School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Alexa Marie Irwin ADVISORS Elana Renee Bernstein, Susan C Davies, Leslie H Picca LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Cultural competence and the ability to effectively serve children and families from diverse backgrounds has increased in importance in social services fields. Professional associations such as the National Association for School Psychologists place particular value on cultural competence for school psychologists due to the lack of diversity in the field and the changing demographics of U.S. schools. Research demonstrates that study abroad experiences during undergraduate or graduate school are an effective way of developing cultural competence in teachers, counselors, and school psychology graduate students. However, there is limited research on the long-term influence of study abroad experiences on the cultural competence of mid-career school psychologists. Ten mid-career school psychologists were interviewed for this qualitative study. The purpose of this study was to examine how a study abroad course, taken during an undergraduate program or graduate program, had any lasting professional or personal impact on mid-career school psychologists. This study further explored other factors that contribute to mid-career school psychologists’ perceived cultural competence. Five themes related to cultural competence emerged following analysis, including: (1) awareness, (2) exposure, (3) cultural immersion, (4) willingness to learn, and (5) professional development. Six themes related to long-term influence of study abroad on perceived cultural competence emerged from the analysis, including: (1) increased openness, (2) different perspectives, (3) learning about other cultures, (4) recognition of our similarities, (5) relating to students from different backgrounds, and (6) contributions to practice. The findings are presented along with implications for future research.

SCHOOL OF EDUCATION AND HEALTH SCIENCES

LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Research suggests that adopting a growth mindset can have positive implications for students’ academic outcomes, adjustment, academic emotions, and motivation. Having a growth mindset is also positively associated with resilience, which is positively associated with psychological well-being. The present study examined the relationship between high school students’ self-reported levels of growth mindset and psychological well-being. Results of a survey given to (n = 85) high school students demonstrated no significant relationship between students’ overall levels of growth mindset andpsychological well-being. Further, results indicated that no significant relationship existed between growth mindset and any individual domain of psychological well-being (i.e., autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance).

ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 First generation college students (FGCS) often face hardships throughout their college experiences, from matriculation to graduation. The FGCS population is growing every year, which increases the urgent need to properly serve them. The University of Dayton is known for making their students feel at home on their campus. Although FGC students currently represent only 6% of the undergraduate student population at the University of Dayton, the university will soon be seeing an increase in this student population with the addition of Flyer Promise and the UD-Sinclair Academy. The demand for services and resources that fit the needs of these students will become increasingly urgent. By utilizing interviews with five current first-generation students, this study highlights the ways in which FGCS navigate an unfamiliar campus environment.

The Effects of Rewards on Motivation Within Higher Education Residential Learning Curricula School of Education and Health Sciences: Counselor Education and Human Services Poster - Course Project, 201910 EDC 574 D1 STUDENTS Megan JF Will ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 The University of Dayton AVIATE Program strives to further studentsâ&#x20AC;&#x2122; learning outside the classroom by educating individuals on the concepts of authorship, interculturalism, and community living within a residential curriculum. AVIATE attendees are rewarded for participation in program events via a point system which is utilized in housing assignments for the coming year. This study aims to discover what motivates students to continue their studies in a residential environment and the effect rewards and teamwork play on motivation and participation. Data compiled by the University of Dayton department of Housing and Residence Life was analyzed to determine how likely students are to attend residential educational programming, the role rewards play in learning, and studentsâ&#x20AC;&#x2122; reliance on teamwork to achieve shared goals. Results indicate that students' motivation levels vary. While the majority of students partake in fewer than 20 AVIATE events each year, overall program participation has grown, particularly with student groups working toward the common goal of rooming together in the upcoming year. This is especially true for 5-student teams who most recently averaged attendance at 36 events per person. The exception lies with students who choose not to request roommates for the following year. These individuals may attend a single AVIATE event during the academic year. Thus, student motivation in residential learning is largely affected by a combination of the creation by teams of shared goals as well as extrinsic reward opportunities.

The conversation surrounding roommate conflicts has already begun, but a majority of past literature has focused on personal characteristics of individuals and their compatibility as roommates. Quantitative research studies have delved into how it impacts the lives of students, including stress, mental health and retention. Yet empirical research has not yet been conducted specifically on the actual dynamics of interpersonal conflict between college roommates. The purpose of this qualitative study is to better understand the experiences of college roommates in conflict at a private, Midwestern institution and how they respond to the phenomenon. With the desire to put student experience at the center of this research, studentsâ&#x20AC;&#x2122; perceptions were shared through semi-structured, in-person one-on-one interviews with the individuals who self-selected to take part in this study. Expressly, this research provides a richer understanding of how roommates react to conflict based upon how nonverbal and verbal reactions within the conflict situation are expressed, what conflict resolution strategies roommates generally use in conflict and how roommates in conflict describe how it has shaped their capacity for coping with the inevitable conflicts of the future. With mental health and overall college satisfaction on the line, this research assists student affairs practitioners in better understanding the dynamics between roommates in conflict and how it shapes their college experience. It provides insight into how student affairs practitioners, especially those who work in university housing, can be better prepared to respond to situations where roommates are in conflict. Inevitably, this information can lead to the creation of better conflict management practices to teach to staff and students in university housing and across campus.

Self-Authorship and Queer Students of Color

School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS John Lewis McGee ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 Self-authorship is an important concept which allows higher education professionals to see the development of students and how students make meaning and create relationships. Higher education for years has failed to examine queer students of color, grouping them under an operative assumption, which assumes that they develop the same way students of color or queer students do. This failure to recognize the intersections of racial and sexual identities has led to the lack of literature written and exploration of queer students of color and selfauthorship. The purpose of this study is to explore the extent to which queer students of color develop self-authorship at predominantly White Institutions. Grounded in the constructivist paradigm, using the narrative inquiry, this study describes the cognitive, interpersonal and intrapersonal experiences of queer students of color in the Midwest. As this study demonstrates, intersectionality plays a critical role in how students identify, make meaning and create relationships often involving the feeling or a need to overcompensate in other aspects of life.

Extrinsic Factors of Academic Probation Attrition of Engineering Students School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Luke Austin Matulewicz ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 Being on academic probation is a stressful time for students. Many programs have been designed to specifically help these students return good academic standing; however, there is mixed success. Academic probation can often lead students to taking an extra semester, delaying their graduate, and/or not finish their degree—all of these causing an issue with retention and graduation rates. There has been an increased focus on a workforce with a science, technology, engineering, and math (STEM) education over the years, making it imperative to colleges and universities to effectively graduate their STEM students. This quantitative data analysis looks to examine extrinsic factors, factors out of the students’ control, of students on academic probation in the School of Engineering at the University of Dayton and the correlation to academic attrition. Using mined university data, this research uses statistical tests to find significate factors of attrition from academic probation.

STUDENTS Joseph J Moore ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 This study seeks to understand the experiences of undergraduate men of color after they gain membership with a historically white, North American Interfraternity Conference fraternity. The significance of this study is derived from the lack of prominent research involving men of color and membership with historically white fraternities. This research allows for the advancement of the Fraternity and Sorority Life field by shedding light on a population of students that is misunderstood and in turn impacting the way professionals interact with students. This research study speaks to the intersection of both the male and student of color identity within the context of historically white fraternities by highlighting the lived experiences of those members. This study collected data through individual interviews with alumni members allowing for a deeper look into the subjects’ experiences. This study speaks to the lived experiences of the subjects’ around the themes of motivations to seek membership, experiences gaining membership, living in community, racial impact on experience, sense of belonging, senses of community and feeling othered.

The Impact of Home and College Tension on Grit in First-Generation College Students School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Kaley Lynn Meyer ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 In the context of higher education, students who have parents with postsecondary degrees have an advantage over those who are first in their families to attend college. One of the most commonly discussed challenges for first-generation students is navigating the tension they experience from living lives in two different worlds: life at home and life at college. Interestingly, however, some literature illuminates how the unique challenges first-generation students face often make them more determined, persistent, resilient and prideful in their collegiate endeavors (O'Neal et al., 2016; Strayhorn, 2013). Scholars have discussed these particular characteristics as signs of grit and studies have shown grit to be positively associated with academic achievement (Duckworth, Peterson, Matthews, & Kelly, 2007; Kannangara, et al., 2018; O’Neal et al., 2016; Strayhorn, 2013). If first-generation students tend to display grit in their educational pursuits, then why are they more likely to drop out of college than their non-first-generation peers (Chen & Carroll, 2005)? This quantitative study is an attempt to dissect this phenomenon to better understand why some first-generation students persist and others succumb to the various challenges they face in postsecondary education. Through utilization of the Grit Scale and the Home and College Tension Scale, this study determines the extent in which perceived tensions between connections to home and college experiences influence grit in first-generation students. With this information, educators and administrators can expand their understanding of the complexities of the first-generation experience and further enhance various supports for this particular population. The findings from this study provide specific implications for future practice and research on first-generation students, grit development and the overlap of the two domains.

SCHOOL OF EDUCATION AND HEALTH SCIENCES

Poster - Graduate Research STUDENTS Marissa L McCray ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 While selection of an academic major is pivotal for undeclared students, many lack direction and struggle to understand the meaning of prescribed, seemingly unrelated general education courses traditionally required in the initial college curriculum. Moreover, many undeclared students grapple with a sense of calling or purpose among academic choices, future careers, and broader facets of emerging adulthood. An interdisciplinary curriculum counters the disconnect between compartmentalized disciplines and helps students recognize connections between disciplines and wider contexts. The purpose of this qualitative case study is to explore how the University of Dayton Core Program shapes undeclared students’ academic major selection and vocational outlook. This study examines Core students who began the program as Discover Arts (undeclared) and evaluates how Core shaped their academic major selection and vocation discernment. Qualitative data was collected from one-on-one interviews with junior Core students who recently completed the 2 ½ year interdisciplinary program. Findings revealed numerous themes and patterns surrounding the academic major selection process and the impact made by the Core Program during discernment. This study assesses future implications for continued best practices and seeks to address a gap in the literature about the influence of interdisciplinary curricula on undeclared students’ choices about academic major and vocational outlook.

How Representation During a College Visit can Influence a Student of Color’s Decision to Attend a Predominately White Institution School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Deidre Danielle Luckett ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 Students attend campus visits hoping to gain an understanding of what universities can offer them as students. Universities have shifted their focus to creating visitation experiences where students feel a sense of belonging before they even apply. Due to the growing understanding of the positive influence of representation, many schools are beginning to showcase campus diversity through various multicultural visitation experiences and making stronger efforts to include diverse groups of students (Boyington, 2017). The purpose of this quantitative research study is to examine how students’ decision of college choice is influenced by the racial/ethnic representation present during their college visit at a predominately white institution. A survey was distributed to current undergraduate students of color at the University of Dayton to reflect upon their experiences during their college visit and how the presence of other students of color, faculty, and staff contributed to their decision to attend the University of Dayton and their overall sense of belonging. This study combines the frameworks of college choice with the students’ needs of positive representation and an environment where they feel they belong.

Student Perception of Parental Involvement in College Orientation

School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Sarah Kathryn Skidmore ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 Much research on orientation focuses on how parental involvement affects retention or overall first-year student success in college. However, there is a lack of research focusing on orientation solely and what happens to students if parents are or are not able to attend with the student. This study uncovers just that, allowing for a shift in focus from retention to the emotional side of a student and how having one or both parents present may or may not affect their emotional transition into college. Orientation is the time where students and families are given as much information as possible to feel prepared for the start of this new journey. The experience can make or break a student’s perception of their new college home, and having parents there adds another whole dimension to a student’s feelings of comfort and support. Through a qualitative, narrative approach, this research delves into the lives of five students who did and six students who did not have parents present at orientation. Students reflect on their perceived levels of anxiousness, preparedness, support, autonomy and independence, ability to meet people, and their space to develop identity and self-authorship all in relation to whether or not their parents were able to attend orientation with them. This study helps student affairs professionals better understand what affect parental presence at new student orientation has on incoming students. It helps institutions decide whether to have more or less parent sessions during orientation. It also helps institutions see how students are feeling when they do not have a parent present, possibly suggesting ways that institutions can provide opportunities for these students to have sessions that still allow them to feel that same type of support as students whose parents were present.

STUDENTS Alysha K Rauen ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 The purpose of this qualitative, phenomenological study is to understand the motivations of commuter students in universities and colleges in the United States who get involved in co-curricular activities, such as recognized student organizations. This study will increase the already very minimal amount of research on commuter students on college campuses and will provide insight that has not been addressed. Understanding these motivations will help professionals better understand this population of students and be able to improve practices to better address their needs. Data was collected through in person interviews (n = 5) between the researcher and students who fit the criteria of being a commuter students and involved in at least one recognized student organization. Themes that emerged from the data were that commuter students are self-motivated to get involved and the distance of their commute does not affect their motivation.

identity development.Findings from this study emerge from interviews with tattooed University of Dayton students about the internal and external messages they have received about tattoos in a society that still connects tattoos with a negative stigma.Early findings suggest that students see their tattoos/the process of getting a tattoo as a way to let the world know that they are an individual, and can link it to some form of their identity. Other early findings suggest that the process of getting a tattoo can be some sort of healing process.Findings from this study can be used in practice by understanding if/why a student links their tattoo(s) to their identity, and offer them a space to open up and talk about what they mean and to help break the negative social stigma that comes with tattoos.

The Effect of Transdisciplinary Pedagogy on Vocation Discernment

School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research

STUDENTS Morgan Kelly Miller ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 The Effect of Transdisciplinary Pedagogy on Vocation DiscernmentIn its institutional learning goals, the University of Dayton includes vocation as one of its goals stating that “all undergraduates will develop and demonstrate ability to articulate reflectively the purposes of their life and proposed work through the language of vocation” (University of Dayton, 2018). How do students on UD’s campus view vocation and in what way are some areas of learning teaching vocation? The purpose of this study is to document and understand a student’s developing understanding of themselves and, in turn, vocation. To this end, I have looked at one program on campus: The Institute of Applied Creativity for Transformation (IACT). IACT teaches a creative mindset that students from many majors and backgrounds learn together to take it back to their own individual areas of study for use in interacting with those curriculums, making IACT’s curriculum and advising transdisciplinary in nature. This study provides valuable accounts and insight into the effects of IACT’s curriculum and advising model and how it effects vocation discernment for undergraduate students who participate in the program. The study is dependent on the data collected and analyzed from interviews with students working toward IACT’s certificate in Applied Creativity for Transformation. This study includes information on how students make meaning of how IACT teaches, how they think about vocation, and if IACT is affecting the meaning of vocation for these students. Risk in Fraternity and Sorority Life: the Policies, Experiences, and Opinions of the Students School of Education and Health Sciences: Counselor Education and Human Services Poster - Graduate Research STUDENTS Ally Katherine Michalski ADVISORS Graham F Hunter LOCATION, TIME LTC Forum, 4:30-6:30 At times it seems as if the word risk is synonymous with fraternity and sorority life. Are there more problems involving students in Greek organizations or does the media make it seem that way? Are female students in sororities more likely to feel unsafe or be subjected to dangerous behavior? Do men and women in fraternities and sororities get lower grades? The purpose of this study was to find out what kind of risk, if any, students in fraternities and sororities feel exist on their campus or nationally. This research was conducted with the intent to learn from students and understand what experiences they have had while participating in Greek-letter organizations. Interviews were conducted with current undergraduate students from two different institutions to find out their thoughts and opinions about risk and their experiences thus far as members of their organizations. The questions were created based off of three topics that were recurrent while preparing to conduct interviews, alcohol consumption, sexual encounters, and individual student development and academics. The conclusions of this research come from time spent with various students from their different respective councils. It shows that while they may have chosen different organizations based on values and needs, many of their experiences when it comes to risk, and as a whole, have been similar.

This is a qualitative research study examining faculty perceptions of their own preparedness prior to leading college students on short-term education abroad programs. Through interviews with faculty members from various departments at the University of Dayton, they were asked to reflect on their experiences with the following: Managing student crisis, conflict and concerns; facilitating intercultural dialogue and reflection; and takeaways from pre-departure trainings facilitated by the Office of Education Abroad prior to leading students on programs abroad. My interpretation

As there are multiple families facing food insecurity, there are a variety of programs that exist within the community aimed at expanding food access.The purpose of this research was to identify the current assets within the community that provide nutrition education and healthy food access in an attempt to combat the food insecurity prevalent in the Twin Towers neighborhood. The objectives of this community assessment were to recognize community assets that lead to increased engagement and empowerment of those residing in the Twin Towers neighborhood. In order to do this, we conducted a semi-structured interview with two key informants from the community and analyzed secondary sources regarding the two aforementioned topics. Findings include the presence of several community assets that can be expanded upon to improve food security of the Twin Towers neighborhood residents. Such assets include Miracle Makers, Mission of Mary programs, New Hope Church, and several others under the Food Access Resiliency Enterprise. Due to the information gained, we recommend working with the current community organizations to develop an asset based intervention to address issues around food knowledge, food access, and food program participation.

Specifically, we focused on the population of female college students in this project. The purpose of this study is to explore the relationship of caffeine on aerobic exercise performance in college aged females. The caffeine consumed by the participants will be 8oz of donut shop coffee from a keurig cup. This will be consumed one hour before exercise and we will measure aerobic exercise performance using a cycle ergometer. There will be a total of 10 female college aged participants of both coffee and non-coffee consumers. We will have the same 10 females exercise one day without coffee and one day with coffee to compare our results. We are interested in looking at the effects coffee has on heart rate, blood pressure, rate of perceived exertion, and exercise performance (survey-based).

More specifically, this study will help determine how different temperature (i.e. hot & cold) will help relieve delayed onset muscle soreness more efficiently. The settings of this project will be to place the participants into a highly heated pool or an ice bath. To collect data, interviews with 4 individuals, 2 males and 2 females, will be conducted. The interviews will be conducted after the individuals exercise to obtain delayed onset muscle soreness (DOMS) information and then either use hot or cold temperatures to relieve it. The exercise will consist of various resistance training focused on the lower body. Participants will exercise their hamstrings, quadriceps, adductors, and so on, which will then lead to the immediate application of heat or cold therapy. The study will also have a control group in order to compare the results to a baseline of the specific exercises without temperature application post-workout. We plan for our data to show results of DOMS in individuals and determine which temperature provides the best relief. The detailed findings will be reported at the symposium.

The purpose of this research is to evaluate in what running environment college-aged individuals perform best, based off of time. Research will be conducted at the University of Dayton RecPlex and an outdoor trail near campus. The participants of this study is non-athlete male and female subjects, aged 18-23 years old. While each participant is completing the three one-mile runs, rating of perceived exertion (RPE), heart rate, and time will be recorded. Specifically, the Borg RPE Scale will be utilized to attain subjectsâ&#x20AC;&#x2122; RPE, and an Apple Watch will be utilized to attain subjectsâ&#x20AC;&#x2122; heart rate prior to and immediately after each run. Achieving a certain percentage of an individual's age predicted maximum heart rate is a valid indicator of work exertion. While data collection is not yet fully complete, we are anticipating that, on average, participants will report the lowest RPEs during the outdoor trail run and the highest RPEs while on the treadmill. Although we are expecting to see similar trends in RPEs, we are anticipating that the females, on average, will display longer times recorded for each timed run than the average male

Some of our objectives of this assessment were to obtain primary and secondary data regarding food and nutrition program participation, safe food and meal availability, safe water availability, and food and nutrition-related supplies availability. Overall, the primary data suggested that a majority of participants walk to get food supplies and obtain their food supplies from Kroger, but some participants also obtain food supplies from Rayâ&#x20AC;&#x2122;s Food Market. Most participants obtain food from these places due to its location close to home. The data also indicated that all participants own a refrigerator, and a majority of participants own a microwave, hot plate burner, and a crockpot. Also, a majority of participants eat food at home but not at a high frequency. The secondary data suggest low ownership of vehicles, a slight decrease in food and nutrition program participation, a slight decrease in annual median income of Montgomery households, high rates of poverty, high safe water availability, and low levels of accessible healthy food providers.Due to these findings, we recommend addressing the barriers to obtaining healthy food available within the Twin Towers environment.

In the spirit of pioneering exercise physiologist and researcher T.K. Cureton, who believed that the “true laboratories in physical education [were] the pools, playfields, gymnasiums . . . ,” this study was field based and conducted primarily at the University of Dayton RecPlex. During the 2019 spring semester, students enrolled in an undergraduate Personal Community Health course offered in the Department of Health and Sport Science exercised w/peers during 5 separate sessions. Team members participated in five (5) sessions conducted during class time while continuing to participate in their own individual exercise regimens outside of class. Two of the (2) in class sessions included pre- and posttest fitness assessments. All in-class exercise and testing sessions were conducted at the University’s RecPlex. Data from pre- and posttest fitness assessment sessions were analyzed and compared using descriptive statistics. Qualitative data from students’ weekly Health Wellness Review Reflections (HWRRs) were analyzed and compared to Insell-Roth (2016) Dimensions of Wellness Theoretical Framework to determine the effectiveness of the PPHPEP.Note: Data analysis for the PPHPEP is a Work in Progress (WIP).

SCHOOL OF EDUCATION AND HEALTH SCIENCES

LOCATION, TIME Kennedy Union 312, 1:40-2:00 Social media is nowadays used by nearly all businesses to promote their brand and reach out to customers. In sports, teams and leagues alike recruit fans at both a domestic and international level. Social media can be used to promote events, players, teams and more within the sporting industry and some strategies work better than others. In this research project, we examined the use of social media by major American professional sports leagues (e.g. NBA) in building international outreach. In particular, the study focuses on evaluating how these leagues leveraged the “glocalized” marketing and communication strategies on social media to better connect with and serve the interests of international fans. Such strategies include creating separate accounts for fans from different countries, using different languages in social media posts, highlighting different news of the leagues that are appealing to international fans, accomplishing different business objectives (e.g. branding, sponsorship, media subscription, & ticket sales) through social media marketing and communication, and much more. A text analysis on the content of the social media posts using data analytical tool DiscoverText will also be conducted and the findings on the major themes of these social media posts will be presented at the Symposium.

STUDENTS Braden Allen Wagle, James Henderson Walton ADVISORS Peter J Titlebaum LOCATION, TIME Kennedy Union 311, 2:20-2:40 Today, social media platforms are used as a way to communicate with friends, stay up to date with trends, follow news, post pictures, etc. But how do businesses and campaigns benefit from social media from a professional standpoint? There are 10 key components to build a successful media campaign. We used strategies from the top companies and sports teams that utilize social media the best in order to create a step-by-step plan. We will focus on market activation and awareness in the community. Creating a great social media campaign can separate great businesses from the ones that never get off the ground. The current campaign we are doing, The Ride 4 Freedom Legacy Tour, will demonstrate how a successful campaign can change a project. We will explain where the ride was before implementing these 10 key components, and compare it to after they were fully implemented.

Legacy: Empowering Students to Give Back

School of Education and Health Sciences: Health and Sport Science Oral Presentation - Honors Thesis

STUDENTS Eric R Schutter ADVISORS Peter J Titlebaum LOCATION, TIME Kennedy Union 311, 2:40-3:00 Most universities struggle to convince alumni to give back to their former institutions, despite the amount of time and energy that schools invest in their students. However, if universities created avenues for alumni to give back to the programs that mattered to them, they would see an increase in student giving from both alumni and current students. There is evidence to suggest that if students are empowered and made aware of the importance of giving, they are more than willing to give their time, energy, and even money back to the programs that helped them along the way.

STUDENTS Alexandra Gisela Delgrande, Ryan Earl Evensen-Hein ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Poverty affects at-risk students’ academic opportunity through its effects on academic achievement, motivation, development, and education quality. Impoverished at-risk students’ academic achievement is affected by their inability to acquire basic needs. This can be shown by these students’ graduation rates, math scores, and retention rates. There is evidence of poverty having a negative effect on graduation rates, retention rates, and test scores. These students’ can appear less motivated or less engaged in the classroom potentially due to their focus on higher priorities. How could you expect a student to worry about a math test when they do not know how they are getting dinner that night? Since these students are unable to acquire their basic needs, they can also encounter developmental problems. These developmental issues refer to social, emotional, and cognitive development as well as can lead to malnutrition and preterm birth. These developmental setbacks hinder these students’ ability to further develop in school. Another obstacle impoverished students can face is poor education quality. Oftentimes, inexperienced or ineffective educators are assigned to schools with higher impoverished student populations. This unfortunate fact, as well as underfunded districts, and the lack of basic school supplies, further disadvantage impoverished at-risk students. Impoverished at-risk students are put at a disadvantage through poverty’s effects on academic achievement, motivation, retention, development, and education quality.

In this presentation, we will explore how the brain learns, stores, and retrieves language, as well as the specific differences between the brain’s activity when learning a first and additional languages. The brain as related to language is complex and is not yet fully understood; however, this presentation will discuss the accepted theories about the brain structures and function connected to language. These theories will describe the processes that learn, store, and retrieve language in the brain. Although there are still discoveries to be made, research has shown that differences exist between learning a first and additional languages. These may include the ease of learning the language, how hard one’s brain must work when processing first and other languages, and even the visibly noticeable effects between using a first or other language. With the former information in mind, we will explain how the neurological structures and processes of language and the differences in brain function that occur while learning a second language as opposed to the first can be used to impact teaching styles for language acquisition.

Goal 4: Quality Education STUDENTS Andrew Michael Buchanan, Maria Christine DiFranco ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 This poster describes the benefits of performing arts in students’ academics, as well as school funding policies that affect the overall success of students. Differences in funding by district and state are explored and how the unequal distribution contributes to school inequality. With the performing arts often being ignored, the importance of funding students’ artistic endeavors is explored, as well as how the performing arts increases students’ academic performance. The performing arts can benefit children in multiple different ways. One way is the use of theatre inside the classroom. Studies have shown that by integrating the arts in other subjects, students’ interest in school increases, and so their performance also benefits. The arts have been shown to increase language skills and interpersonal skills, which help underprivileged kids especially since often they are behind in these rudimentary skills. These skills do not have to be learned in a classroom, however, and can be learned if students participate in the performing arts outside of school as well. These theatre experiences show benefits such as cooperative skills and can be used in any grade. They should not be ignored in early childhood classes, but more frequently have been shown to decline in schools.

Work vs Play in classrooms

School of Education and Health Sciences: Teacher Education Poster - Course Project, 201910 EDT 110 H1 Goal 4: Quality Education STUDENTS Hailee M Cain, Katelyn Marie Gillotti ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 We will be exploring the benefits of play in early childhood classrooms and beyond. Research shows that there are significant benefits to play, but recently school systems have begun to phase out the importance of play in their curriculums. Instead increasing academic rigor has taken over the life of the everyday classroom. While academic skills are vital, social skills are equally as important for student's proper development. Teachers and educators of all grade levels must find methods to incorporate both cognitive and social emotional development into their classrooms. With the implementation of several required standardized tests, school districts have been forced to focus only on academic scores in order to receive good grades on these large-scale assessments. The consequence of these tests is that students have been given less time to work on and cultivate creative activities and ideas in the classroom, including time for free play. Methods such as intentional teaching have emerged to help teachers combine both academics and play or exploration into the same lesson plans. The goal of our research will be to explore both the benefits and drawbacks of prioritizing play in the everyday classroom.

Individualized Learning Plans

Specifically we will be focussing on the use of alternative classrooms and alternative scheduling within high schools and the benefits that come with them.Through the use of flipped classrooms and the inclusion/choice of electives, specifically in the arts, one can receive a more well-rounded education that will help them in both the world and in their further education. Going beyond the traditional ways of earning credit in high school can help the students develop a more personalized education, therefore ensuring more of a balance in the education of the whole person. Giving students more choice and flexibility within their schedule will allow them to focus on their passions and become more advanced in their interests. Additionally the integration of arts within a student’s education through both electives and within other classes can lead to benefits in other academic areas, allowing for students to get the most out of their high school experiences. Both alternative classrooms and alternative scheduling provide a more individualized approach to education which allows for students to gain control of the path that they take through their secondary education experiences. By giving students an ability to choose gives them more of a sense of ownership and responsibility when it comes to their education which oftentimes leads to better outcomes in their education as a whole.

For one person, they are researching the negative effects of sex education discrepancies on students. For another person, they are researching the benefits of a STEAM education. Finally, another member is researching outdoor education in urban schools and its impact. Together, this combined research is aimed towards the education of the whole person. Both outdoor education and sex education are, in a way, a science. Regarding sex education, adolescents are informed about the importance of consent, physical safety, and emotional safety. Each of these aspects of sex education is founded in scientific research of the effects of adolescent sexual activity on the human body and mind. For outdoor education, a hands on education in science can increase intrinsic motivation both inside of the classroom and out. For STEAM education, students are taught a new approach to learning as a way to solve problems in their community. Ultimately, our combined research informs how to educate the whole person.

Through the combination of individual research, the information provided shows that the inclusion of students with disabilities in the classroom lets all students make greater strides in their academic successes through the diverse learning levels. This diversity decreases the stereotypes that surround those with disabilities when their neurotypical peers see all their shared characteristics. Inclusion fosters strong relationship formation between students with disabilities and students in general education. Inclusion with peer support arrangements create a classroom that is full of success.The connection peers get to make with the students with disabilities helps the overall well being of students by allowing peers and students with disabilities to both thrive inside the classroom and receive benefits from this learning experience. When educators teach students with disabilities strategies that improve their learning, students are better able to articulate and express their ideas. This allows students with disabilities to more confidently engage in the classroom, but also with the attention and help they need from the teacher because of their disabilities, these students will begin to see and take pride in their academic success. Inclusion of students with intellectual and learning disabilities creates a more diverse learning environment where everyone can succeed.

Biases in the Classroom

Goal 10: Reduced Inequalities STUDENTS Matthew J Frabutt, Lanny Glenn Sparks, Anna Catherine Wolfe ADVISORS Jennifer T Christman, Susan M Ferguson LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Students are subject to the consequences of a variety of biases present in the classroom based on their genders, personality styles, or academic abilities reflected in their grades. The first inequality present in the classroom can be observed through the different ways teachers treat male and female students. The types of attention teachers give to students, as well as their beliefs in students’ academic capabilities, differ depending on whether the student is male or female. Whether they be conscious or unconscious, these biases have a profound effect on widening the academic achievement gap between girls and boys. Teachers may also be biased in the ways in which they interact with extroverted and introverted students. Teachers and the educational system celebrate and cater to the needs of extroverted students rather than to introverts. The quieter students in the classroom may be perceived as “disengaged” or as students who hold negative attitudes about learning. Yet, although their personalities may not outright display it, the introverted students can prove to have the brightest minds or sharpest attention spans, and teachers must not fail to engage these students and give them adequate acknowledgement. Lastly, teachers may show a bias toward students who possess a higher academic aptitude rather than at-risk or lower performing students. This bias allows for the “smart” kids to excel further and the “dumb” kids to fall further behind. This shows a bias in the classroom because a student’s true capabilities may not be able to be properly expressed in the current grading system.

Crystallization Kinetics for Homo- and Hetero-genous Thin Films of Tungsten Selenide School of Engineering: Chemical Engineering Poster - Graduate Research

STUDENTS Rachel Habib Rai ADVISORS Christopher Muratore LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Single to few-layered Group-VI semiconducting transition metal dichalcogenides (TMD) are new materials that exhibit versatile physical properties, such as sizable direct band gaps, that promise new potential for many electronic and optoelectronic devices. A prototypical TMD, Tungsten Selenide (WSe2) exhibits captivating properties such as room temperature photoluminescence temperature. However, the integration of WSe2 and other TMDs into devices is currently limited due to the inaccessibility of scalable techniques to fabricate high quality large area thin films. This impediment can be resolved by understanding and optimizing the kinetics of film growth. Thus, our work encompasses innovative techniques to study the crystallization kinetics of thin amorphous homo- and hetero-genous films of WSe2. We begin by sputtering thin amorphous films of WSe2 on flexible and rigid substrates. We then crystallize the deposited films by supplying enough energy for crystallization via broadband radiation, nanoscale beams, and in situ Raman Spectroscopy. Magnetron sputtering is selected as the deposition technique due to the low temperatures involved, thus allowing deposition on polymer substrates. Furthermore, modulation of the energy flux during magnetron sputtering provides an opportunity to model homo or hetero crystallization by forbidding or permitting the presence pre-existing nuclei, respectively. Our employment of various crystallization techniques allows for methodical study of the influences of seeds on 2D nucleation and growth kinetics. Results show that homogenous crystallization has a lower nucleation due to the small seed size. Such finding is systematically explained by crystallization theories that relate the critical radius size of the seeded materials to energy barriers. The newly founded relationship between deposition parameters, activation barriers, and film quality of WSe2 is applicable to other TMDs. Thus, our work significantly contributes to the advancement TMDs and eases their incorporation in future electronic devices.

Alternative Routes for Ethanol Extraction Using Green Solvents and Nanotechnology School of Engineering: Chemical Engineering Poster - Course Project, 201910 CME 499 03 Goal 7: Affordable and Clean Energy STUDENTS Joseph Daniel Knurek ADVISORS Erick Vasquez LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Ethanol has emerged as a promising alternative biofuel source in recent years. However, current separation techniques for ethanol processing require high energy consumption, causing large scale production to be inefficient. One area of potential improvement in separation cost could be in nanoparticle-enhanced liquid-liquid extraction; removing ethanol from an aqueous solution utilizing castor oil as a green solvent. A castor oil-ethanol mixture would allow for easier separation and purification of ethanol, due to the large difference in the speciesâ&#x20AC;&#x2122; boiling points. It is hypothesized that adding lignin-coated iron oxide nanoparticles to the aqueous solution would increase the transfer efficiency of the solute. Additionally, these nanoparticles would render the mixture superparamagnetic properties, allowing for a magnetic field to be induced around the fluid in separation, further increasing the transfer efficiency due to the magnetic motion in the liquid. This work focuses on setting up prototype equipment that includes a mixer with a magnetic field generator for liquid-liquid extraction magnetic separations. The ultimate goal of this research is to determine if an increase in ethanol transfer efficiency can be seen from the addition of the lignin coated magnetic nanoparticles to the aqueous and green solvents mixture, and if a further increase in transfer efficiency can be seen from the introduction of a magnetic field to the fluids during separation.

Characterization of Novel Phosphorus-Based Flame Retardants in Epoxy Resins School of Engineering: Chemical Engineering Poster - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Mustafa Mukhtar ADVISORS Vladimir A Benin, Donald A Klosterman, Alexander B Morgan LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 This poster summarizes the results of a series of ongoing experimental investigations into the curing reactions between a novel phosphorus flame retardant (FR) and epoxy resin. Epoxy resins are used in society in a wide variety of industrial applications including aerospace, infrastructure, transportation, electronic, marine, and sporting goods industries. The novel flame retardant was synthesized and provided by UD Chemistry Department faculty. The FR includes both primary and/or secondary amine functional groups which allow it to potentially react with the epoxy resin through covalent bonding. Previous work involved examination of several similar flame retardants which showed good results in terms of curing behavior and flammability properties. Despite these results, scale-up of the formulations from small scale (~ 1 gram) to a larger scale (10s of grams) led to unexpected results, for example, the generation of gas bubbles during cure which was not observed in the initial small scale studies. In response, a series of experimental mixing formulations and curing conditions were investigated to provide further insight. Curing conditions were characterized by various physical and thermal properties using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). In the current study, we will try to overcome some of these problems that were experienced in the previous study in order to make controlled samples for further flammability testing.

Environmental Effects of Single Use Plastic Water Bottles Versus Reusable Water Bottles School of Engineering: Chemical Engineering Poster - Course Project, 201910 EGR 374 01

236

While bottled water can be more convenient on the go, these plastic water bottles contain harmful substances called polyethlene terephtalate (PET) and bisphenol A (BPA), which are both extremely dangerous to human health and the environment. The production of one plastic bottle uses energy, emits toxins into the air and uses more water to produce than actually put in the bottle for drinking. The bottles take hundreds of years to decompose, filling our landfills at an alarming rate. 38 billion water bottles end up in U.S landfills each year, which equates to about two million tons. Reusable water bottles save fossil fuels. If you were to fill one disposable plastic bottle a quarter of the way up with oil, it would represent the amount to make it. With just one person switching to a reusable water bottle, it would keep 2580 balloons of CO2 out of the air per year. If Americans were to switch to reusable, you will feel better about your commitment to the Earth!

Gas Chromatography Applications: Ethanol concentration and SCFA Detection in Listeria School of Engineering: Chemical Engineering Poster - Independent Research

STUDENTS Paul Robert Maricocchi ADVISORS Yvonne Y Sun, Erick Vasquez LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Gas Chromatography (GC) is a separation technique for volatile compounds that involves the vaporization of a sample through an injector. Then, the vaporized sample is carried by a gas moving through a stationary phase (column) packed with a gel or a solid until reaching a detector. Recently, the CME department acquired a GC system with exchangeable detectors and columns to promote teaching and research within the program. During the 2018 Spring semester, the gas chromatography equipment was mastered by learning its fundamental aspects and correct functioning. This summer, through the SURE program and to enhance interdisciplinary collaboration across Units and Departments within the University of Dayton, this work developed GC analytical methods for use both in the classroom and in research for the identification of various compounds. A method was developed for the Senior level CME Unit Operations course, on which ethanol and water samples from a distillation column are analyzed to determine the composition of the binary mixture. In terms of research, Dr. Vasquez’s NEMlab is also interested in determining the concentration of ethanol in water after liquid-liquid extraction using castor oil and magnetic nanoparticles coated with biopolymers from trees. Additionally, Dr. Sun’s microbiology lab works with a bacteria called Listeria monocytogenes as its model organism, and there is an interested in determining short-chain fatty acids (SCFAs) as a new form of biomarkers whose concentrations can be linked to health. Specifically, the lab is interested in the amount of SCFAs that are produced by Listeria, and requested the development of a GC method for this purpose, which was successfully generated using a new column and a flame ionization detector. Both characterization methods were successfully created and saved on the GC instrument and will have a significant impact in the advancement of interdisciplinary research efforts at UD.

Solids Suspension in Unbaffled Vessels Using Vertical Off-Center Agitators School of Engineering: Chemical Engineering Poster - Independent Research

STUDENTS Dillon Patrick Moher ADVISORS Eric E Janz, Kevin J Myers LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Solids suspension via mechanical agitation has been studied extensively, with most of these studies being performed in baffled vessels. Baffling promotes axial flow that provides the desired performance with minimized capital and operating costs. While most studies focus on fully-baffled conditions, there are solids suspension studies that consider reduced baffling. An example is the work of Drewer et al. (1994) who reported advantages to using shorter baffles that do not extend to the tank base when agitating high concentration solid-liquid suspensions. Similarly, Myers et al. (2005) found that hydrofoil impellers can generate top-to-bottom motion with limited baffling, providing the opportunity to achieve solids suspension without full baffling. Baffling is not used in some applications, often motivated by the desire to promote cleanliness and avoid the potential for fouling. Very limited information is available concerning solids suspension in unbaffled vessels. In their study of solids suspension using angle-mounted agitators in unbaffled vessels, Myers et al. (2011) noted that the just-suspended speed in this configuration is typically seventy-five percent higher than with a vertically-mounted agitator in a fully-baffled vessel. Angle mounting is not always an acceptable approach, particularly for larger agitators whose weight leads to large forces on the agitator shaft and mounting structure. In these instances, vertical off-center agitator mounting may be used in an unbaffled vessel. Moving the agitator off the vessel centerline reduces swirl that leads to near solid-body rotation that often makes meeting agitation objectives challenging. Little information has been published about the performance of vertical off-center agitators in unbaffled vessels, and the study described in this presentation characterizes the effect of impeller type, size, and off-center location on the speed, torque, and power requirements for solids suspension in this configuration.

Generation of Silver Nanoparticle Pharmacokinetic Profiles in a Lung Model School of Engineering: Chemical Engineering Poster - Honors Thesis

STUDENTS Rachel Marie Galaska, Stephanie A Miller ADVISORS Kristen Krupa Comfort LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Nanomaterial technologies are becoming increasingly prevalent in consumer and industrial applications, including drug delivery, energy harvesting, environmental applications, and medicine due to their unique physiochemical properties. As nanomaterial use increases, so too

238

does human exposure. This has made it progressively more important to understand the toxicological effects of nanomaterials and their interactions with the human body. Silver nanoparticles (AgNPs) are one of the most commonly used nanomaterials due to their antibacterial properties. As inhalation is one of the most common exposure routes, understanding the toxicity of these AgNPs on lung tissue was studied. Using A549 cells for a lung tissue model, AgNPs of two sizes, 10 nm and 50 nm, and two different coatings, citrate and polyvinylpyrrolidone (PVP), were studied. Toxicity analysis was performed to determine the effects of dose on cell viability. Pharmacokinetic profiles in static conditions were developed using deposition analysis. Future work will include deposition analysis on dynamic conditions to replicate conditions within a body. This work is part of a larger project to develop an enhanced microcellular model (EMM) to bridge the in vitro - in vivo gap and characterize nanomaterials, evaluate biological responses, and develop pharmacokinetic profiles.

Development of the Solar Thermal Adsorptive Refrigerator (STAR) School of Engineering: Chemical Engineering Poster - Honors Thesis

STUDENTS Joshua Wayne Romo ADVISORS Amy R Ciric LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The Solar Thermal Adsorptive Refrigerator (STAR) project at the University ofDayton seeks to bridge sustainability and the need for efficient refrigeration indeveloping communities. Cost-effective construction, operation and maintenance, aswell as the use of environmentally benign and sustainable materials, give STAR greatpotential in the realm of humanitarian engineering. Furthermore, renewably-poweredrefrigeration technology has the potential to greatly reduce the amount of harmfulemissions released to the atmosphere. A STAR utilizes ethanol and activated carbon toproduce cooling. This is done by decreasing the pressure of the system to allow liquidethanol to vaporize at lower temperatures. To vaporize, the ethanol draws in energyfrom its surroundings, creating the cooling effect of a STAR. Although ethanol is notwidely used in adsorptive refrigeration, it was selected for this application because itis easy to produce, non-toxic and widely available.

investigating the impact of raising the speed limit on crash severity specifically with interest with large trucks and buses on rural freeways in Ohio.Statewide crash data have been obtained from the Ohio Department of Public Safety (ODPS) between January 1, 2010 and December 31, 2017. Given the numerous number of rural freeway segments located all over the state and traffic volumes for each segment over the study period are not easily obtainable, therefore the use of standard observational before/after study empirical Bayes (EB) method is not feasible in this case. This research will utilize the time series analysis model, which is a statistical method that can take care the differences in crashes occurring in different years and recognize trends in different periods of times. In essence, time series analysis is a statistical technique that deals with time series data, or trend analysis. Time series data means that data is in a series of particular time periods or intervals. Currently we are analyzing the data and the study will be completed before the Stander Symposium date.

Medical Imaging to Patient Specific Additively Manufactured Implant School of Engineering: Electrical and Computer Engineering Poster - Course Project, 201853 EXP 305 P1 Goal 3: Good Health and Well-Being STUDENTS Monica M Yeager ADVISORS Amy T Neidhard-Doll LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 As of 2018, there are only standard sized, cast molded hips available to patients requiring hip implants. However, everyone has a unique body, so a cast molded hip implant will fit people differently. Personalized additively manufactured, or 3D-printed, implants created from a patientâ&#x20AC;&#x2122;s own computerized tomography (CT) or magnetic resonance imaging (MRI) images may provide numerous benefits. A main benefit would be that the implant would provide a personalized fit for the patient, as it would be made from scans of his or her own body. With a personalized fit, there would be reduced surgery and recovery time. For people with a physiological abnormality, a customized solution may be printed for reconstructive surgery. Another benefit would be for surgeons who could 3D print their patientâ&#x20AC;&#x2122;s bone for pre-surgical planning, such as planning screw placements. As the baby boomer population ages, the commercial market for 3D-printed joint replacements is expected to soar over the next decade. The goal of the research conducted here is to demonstrate a prototype process for patient specific, additively manufactured hip implants made from Digital Imaging and Communications (DICOM) images of human femur bone, leading to additional research on imaging of trabecular bone for biomimetic lattice development.

Multi-Dimensional Lung Segmentation using Deep Learning School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 3: Good Health and Well-Being STUDENTS Dhaval Dilip Kadia ADVISORS K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 The ultimate goal of science is a safer & healthier society and greater humanity. If the computer analyzes medical reports precisely, then enough time can be allotted to the individual patient; diagnosis can be accurate, time-efficient, cost-effective and labor saving. The objective of this research is performing 3-dimensional semantic lungs segmentation, by applying Deep Learning (DL) based methods on the sequence of Computed Tomography (CT) scan images. The motive is to design the 3-dimensional Neural Network architecture based on current 2-dimensional architecture, that is offering state-of-the-art performance, experimenting and evaluating it for improving its performance. The U-Net is a convolutional neural network that is a decent architecture for biomedical image segmentation, and applicable in volumetric segmentation. The proposed work will use the 3-dimensional patch in Recurrent Residual Convolution Neural Network (RRCNN) based U-Net (R2U-Net), applied on the sequence of CT scan images. These computational methods can replace the conventional methods, and overcome their limitations of time delays, the absence of a doctor, and unavailability of instruments. A large number of high-resolution CT images make numbers of slices, and some of the lesion features are not obvious, which leads the heavy work for doctors. The advantage of 3D imaging over 2D imaging is achieved by processing the higher dimensional data. 3D medical imaging can extract more features and surrounding information; that is helpful for the diagnosis. The output can be further helpful to recognize cancerous tumor with its volume inside the lungs. The proposed work will provide more opportunities to explore different modalities of medical imaging.

Skin cancer is one of cancer type that has a significant impact on society in the United States and across the world. Recently, several Computer-Aided Diagnosis (CAD) system papers have been presented. However, there is still an opportunity for further development in the accuracy of its diagnosis. In this research, we propose an algorithm for skin cancer segmentation and classification at a more treatable stage. Our current approach is computationally efficient and combines information from both deep learning and handcrafted features. Our system creates robust hybrid features that have a stronger discrimination ability than single method features. These features are used as inputs to a decision-making model that is based on a Support Vector Machine (SVM) classifier. Our results evaluated online validation and test databases. Our score was 0.841 on the validation dataset and 0.701 on the test dataset for the classification task. We participated in the ISIC Challenge 2018, being ranked 59th for disease classification and 85th for skin lesion segmentation out of 141 methods listed on the competition leaderboard. These statistics do not include the rankings of the groups who did not qualify for the leaderboard. Also, it is important to note that many of the successful methods that were ranked highly used additional external data for training. The ISIC 2018 competition does not provide the external data that they used. We only utilized the competition which provided data for training.

Medical Image Segmentation using Deep Convolutional Neural Networks School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

STUDENTS Zahangir Alom, Ranga Burada ADVISORS K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 Deep learning (DL) has been evolved in many forms in recent years, with applications not only limited to the Computer Vision tasks, expanded

242

towards Autonomous Driving, Medical Imaging, Bio-Medical Imaging including Digital Pathology Image Analysis (DPIA), and in many other forms. Deep Convolutional Neural Network (DCNN) methods such as LeNet, AlexNet, GoogleNet, VGGNet, ResidulaNet, DenseNet, and CapsuleNet within the DL has been very successful in object classification and detection problems on a very large scale publicly available data set. Due to the great success of these DCNN methods, researchers have explored these methods to other imaging areas such as medical imaging problems, where there is a greater need for automated computer algorithms to make the diagnosis quick and cost-efficient, specifically for image classification, segmentation, detection, registration, and medical image data processing. Several state of art methods that provided superior performance in medical image segmentation such as Fully Connect Networks (FCN), SegNet, DeepLabs, U-Net, V-Net, and R2U-Net have outperformed hand-crafted machine learning algorithms. These models have been tested on several medical imaging and DPIA data sets but have not been explored on multi-organ segmentation, so the primary goal of this proposal is to explore more on these state of art models and test on several publicly available multi-organ segmentation data sets. The quantitative and qualitative performance will be evaluated against existing models using different performance metrics including, Accuracy, Sensitivity, Specificity, F1-score, Receiver Operating Characteristics (ROC) curve, dice coefficient (DC), and Mean Squared Error (MSE).

STUDENTS Brad Richard Sorg ADVISORS K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The semantic interpretation of the human language is very complex and diverse making natural language processing an interesting task for researchers and engineers. Natural language processing is a subfield of machine learning focusing on enabling computers to understand and process human languages. Although computers do not have the same intuitive understanding of natural language like humans do, recent advances in machine learning have enabled computers to perform many useful things with natural language like text classification, language modeling, speech recognition, and question answering. Computers are able to accomplish these tasks by learning the deep contextual representations of words including both the syntax and semantics. Through the use of recurrent neural networks, long short-term memory units, temporal convolution networks, and different language embedding models, computers have made significant strides in their ability to interpret and understand human language. With large volumes of textual data available and the need to structure the unstructured data source that is human language, the area of natural language processing will continue to be of interest.

Quaternion Neural Networks for Sequence Classification School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

STUDENTS Cameron E Long ADVISORS K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 Recently the field of deep learning has made significant advancement, included in this category is the subject of sequence classification. Recent research has shown that traditional sequence processing deep learning architectures such as the Long Short-Term Memory cell (LSTM) or the Gated Recurrent Unit (GRU) can be replaced by Dilated Fully Convolutional Networks called a Temporal Convolutional Network (TCN). Other research has shown that by representing deep networks with complex and quaternion numbers, the networks tend to show improved convergence while using significantly less learned parameters. We combine these two observations to create a Quaternion Temporal Convolution Network (QTCN), and show its performance on sequential classification tasks.

On-Chip Memristor Back-Propagation with detailed Op-Amp Circuit School of Engineering: Electrical and Computer Engineering Oral Presentation - Graduate Research

STUDENTS Baminahennadige Rasitha Fernando ADVISORS Tarek M Taha LOCATION, TIME Kennedy Union 211, 1:00-1:20 In the present world, high tech devices are used in day to day life for number of applications replacing human labor. These devices produce tremendous number of precise computational data with the help of fine sensors. The most important thing to consider is processing those data into decipher patterns within it. Data processing involves learning to analyze and categorize the data in image processing, face recognition, pattern recognition, etc. Deep neural networks algorithms are very popular for this analysis. Graphics Processing Unit (GPU) that is expensive in terms of power and area consumption is used for these types of computations. Memristors are nanoscale devices that can retain a number even when the power is turned off. They use their physical properties that make them more effective than computers. Also, these memristors can be a suitable alternative for the complex applications as UAVs, robots and adaptive controls where it need low power. The objective of this proposal is to develop the memristor circuit with pragmatic behavior with the transistor implementation of op-amp circuit instead of the ideal performance. This new change allows memristive neural networks more into realistic behavior and can be implemented at higher speeds and lower power (than GPU), like the existing circuit with a minor penalty or better.

Control of Unbalanced Power Sharing in Islanded AC Microgrid with Balanced and Unbalanced Loads School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 7: Affordable and Clean Energy Goal 11: Sustainable Cities and Communities STUDENTS Ahmed S Alsafran ADVISORS Malcolm W Daniels LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Managing power sharing between islanded microgrids adds additional capability to existing Smart Grid configurations enabling otherwise isolated microgrids to share power. In geographies where population centers are widely dispersed and particularly, in countries that lack a robust and effective grid, these technologies enable growth in consumption and improved supply security when isolated microgrids are interconnected with feeder lines to shared loads. The challenge is to effectively control this power sharing capability in an environment where microgrid performance is substantially load dependent and where the interconnection capabilities between microgrids often grows organically to meet demand. The proposed control has advantages over other methods since it does not require communication capabilities between the interconnected microgrids and does not require knowledge of feeder line models.This paper addresses a proposed control system design for these systems that has a hierarchical structure to manage power sharing among distributed generation (DG), low voltage AC islanded microgrids with unbalanced loads. The proposed control consists of three parts. First, an active power (P) â&#x20AC;&#x201C; frequency (f) droop control and a reactive power (Q) â&#x20AC;&#x201C; voltage (V) droop control (P/f and Q/V) are used to enable the active and reactive power sharing between two interconnected DGs. Since this droop control is unable to share unbalanced power effectively, a negative phase sequence virtual impedance control is added as a second control to regulate the distribution of unbalanced power. Third, an unbalanced power and small signal frequency droop control is added to adjust the impedance value (L v) in the negative phase sequence virtual impedance control to force the negative sequence current to reach the steady state operating point achieving unbalanced power sharing.The proposed control scheme is theoretically designed the effectiveness of this proposed control scheme is evaluated through simulation studies. The impact of both the feeder line model and the unbalanced load on power sharing effectiveness are investigated.

A CTC and D2D based Network Architecture for Reliable and Energy-Efficient Public Safety Communication School of Engineering: Electrical and Computer Engineering Poster - Graduate Research

Goal 11: Sustainable Cities and Communities STUDENTS Jielun Zhang ADVISORS Feng Ye LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Public Safety Communication (PSC) is responsible to provide reliable communications between the first responders and the victims in public safety scenarios. Some state-of-the-art wireless communication technologies, such as Cross-Technology Communication (CTC) and Deviceto-Device (D2D) communication, are providing more possibilities of the connectivity amongst different communication devices. For instance, CTC enables communications between heterogeneous wireless devices (e.g. Wi-Fi, ZigBee, and Bluetooth) operating in the same ISM band, and D2D communication allows direct communication between wireless devices without traversing a base station. These features make them be promising to be applied for reliable PSC network establishments. They can replace those traditional wireless communication technologies which are not specially designed for PSC networks. In this research work, we propose a novel PSC network architecture based on CTC and D2D communication technologies. To be specific, we propose a novel device clustering scheme to expand the coverage of the PSC network. Cluster heads and cluster gateways in the scheme are chosen from a group of user equipment (UE) based on particular metrics, e.g., residual battery power, received signal strength indicator, etc. Moreover, we propose a scheduling scheme for managing the UE in our PSC network to improve energy efficiency. The simulation results demonstrate that our proposed PSC network architecture can provide reliable public safety communications with high energy efficiency.

Synthetic Aperture Radar (SAR) Image Analysis of Barrow Area School of Engineering: Electrical and Computer Engineering Poster - Independent Research

STUDENTS Ming Gong ADVISORS K. Asari Vijayan LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 With an increasing volume of digital image data obtained from various aircraft and satellite sensors, remote sensing image analysis is becoming more and more important. Effective use of this remote sensing image requires an accurate extraction of information contained in the data. Many image processing and analysis techniques have been developed to aid the interpretation of remote sensing images and to extract as much information as possible from the images. Relevant applications are constantly expanding, from all kinds of land use and land cover mapping applications (such as glaciers and sea ice) to detect and track air pollution and oil leak, the mineralogy of other measurement of earth's surface and atmosphere. The objective of this research is to study the processes of Arctic coastal environment at the intersection between the marine, terrestrial, atmospheric and cryospheric environments. We use ground-based and remote sensing observations to create an integrated Synthetic Aperture Radar (SAR) image processing system for segmentation and classification based on different types of surface in Barrow area.

produce energy in small quantities. This work explores the optimization of energy trading between two prosumers, each of which consists of a load, renewable supply, and energy storage. The problem is described within a model predictive control (MPC) framework, which includes a single objective function to penalize undesirable behavior such as the use of energy from a utility company. MPC integrates future predictions of supply and demand into current dispatch decisions. The control system determines energy flows between each renewable supply and load, battery usage, and transfers between the two prosumers. At each time step, future predictions are used to create an optimized power dispatch strategy between the system prosumers, maximizing renewable energy use. Modeling results indicate that this coordinated energy sharing between a pair of prosumers can improve their overall renewable penetration. For one specific choice of prosumers (mixed residential-commercial) penetration is shown to increase from 71% to 84%.

Machine Learning for Cyberattack Detection

School of Engineering: Electrical and Computer Engineering Poster - Honors Thesis

STUDENTS Kayla D Chisholm ADVISORS Chris G Yakopcic LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Over the last two years, machine learning has become rapidly utilized in cybersecurity, rising from almost non-existent to currently over half of cybersecurity techniques utilized commercially. Machine learning is advancing at a rapid rate, and the application of new learning techniques to cybersecurity have yet to be investigated. The presented work discusses the use of novel machine learning algorithms for network intrusion detection. Typically, this type of network intrusion detection system operates based on a set of rules programmed to recognize known attacks and intrusion techniques. However, this detection method does little to prevent new, or ‘zero day’ attacks. On the other hand, a detection system that uses machine learning could analyze patterns in network data in real time to determine attack likelihood. To test the efficacy of machine learning and neural network algorithms for network security, we use publicly available data sets to ‘teach’ these neural systems what an attack may look like. After training, the system will be tested to determine how well it learned the features contained within the input data. Our results show accuracy and error rates of the algorithms that have been implemented.

Diffraction-limited optical focusing with arbitrarily oriented magnetic field School of Engineering: Electro-Optics and Photonics Poster - Graduate Research

STUDENTS Sichao Zhou ADVISORS Qiwen Zhan LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 In this work, an approach to create diffraction limited optical focal spots with arbitrarilyoriented magnetic dipolar field components in 4Pi microscopy configuration is proposed.This is achieved by focusing two counter-propagating modulated vector beams consisting ofcomplex intensity and polarization distribution. Through combining the magnetic dipoleradiation pattern and the Richards-Wolf vectorial diffraction method, the requiredilluminations at the pupil plane of a 4Pi focusing configuration for the reconstruction ofmagnetic dipole focal field are found analytically. Furthermore, the orientation of thedoughnut shape focal field can be rotated arbitrarily by modulating the pupil field distributioncarefully. As an extension, a three-dimensional optical bubble encloses a transverse spinmagnetic field can be obtained by introducing a second magnetic dipole oriented in theorthogonal plane with appropriate amplitude and phase differences

Optothermal bubble not only offers rapid fabrication of SERS substrate but also helps to locally increase the concentration of pathogens or chemicals attached on SERS to improve sensitivity of chemical and biosensing platform. This work offers an affordable, rapid and ultra-sensitive detection method for efficient chemical and bio-sensing application.

GeSn Gain Spectrum Measurement and GeSn-on-Si Mid IR Laser Development School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

STUDENTS Zairui Li ADVISORS Imad Agha, Jay Mathews LOCATION, TIME Science Center 62, 2:00-2:15 Molecules (from 2-20 μm) and atmospheric transmission (transmission windows of 3-5 μm and 8-13 μm) can experience strong characteristic vibrational transitions at mid-infrared spectral region. Which attract many researches on developing Mid Infrared lasers play an important role on spectroscopy, materials processing, chemical and biomolecular sensing, security and industry. The recent success in epitaxial growth of GeSn on-Si brings new development path on Mid Infrared. Si-based laser could also dramatically reduce costs for telecom components. High-performance computing will require advances in technology, and optical interconnects are one key component to increasing computing power. In this presentation, experimental results of amplified spontaneous emission of optical pumped GeSn waveguides within the IR range, will be presented to show a promising further of developing on-Si Mid Infrared laser. We will also show an experimental characterization of Ge and GeSn optical gain spectrum with pump probe system. This will help further understanding the material properties about optical emission of Ge and GeSn alloy leads to an enhancement and add progress on the development of on-Si GeSn Infrared laser.

Confocal Scanning Imaging System for Surface Characterization in Laser Additive Manufacturing Systems School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Yujie Yang ADVISORS Thomas Weyrauch LOCATION, TIME Science Center 62, 2:30-2:45 Although laser additive manufacturing (LAM) of metal parts is increasing its share in manufacturing in areas such as aerospace, tool making and medical industries industry, parts often do not have sufficiently consistent quality. This is due to variations in a number of process variables, for instance powder size distribution and powder density. It is therefore desirable for future LAM systems to implement feedforward and feedback control of laser power and laser beam footprint so that they adapt to different metal powder conditions.For characterization of the surface of metal powder and the solidified metal, we built a bench-top experimental setup of a confocal scanning imaging system based on a fiber transceiver with oscillating fiber tip. A laser beam is transmitted by the fiber tip and focused on the surface. The laser light is reflected and scattered towards the fiber and part of that light is coupled back into the fiber, from where it is guided toward a photodetector. Recording the photodetector signal while scanning of the fiber tip along one axis and moving the surface in the orthogonal direction provides an “image” of the surface. We evaluated the confocal imaging setup with targets of known scale, such as a USAF 1951 resolution chart and a calibrated cast microfinish comparator. We will discuss processing of the recorded images (such as standard deviation and histograms of pixel values or spatial spectral densities and spatial auto-correlation functions) to determine strategies for retrieval of surface characteristics of different materials.

actively and efficiently to light, with the ability to emit or receive in the infrared region, could be used to achieve infrared photonic devices on silicon. Ge is a promising candidate due to its lower band gap and its ability for direct band gap emission. It has been reported that alloying Ge with Sn helps to change the band structure of Ge by lowering the band gap and increasing the efficiency of optical absorption and emission. Thus, GeSn alloys represent a class of materials with a tunable band gap for building photonic devices like photodetectors, LEDs, and even lasers for a variety of applications. In this work, we explore the tunability of optical emission by measuring photoluminescence from GeSn thin films with varying concentrations of Sn.

Hyperdoping silicon for intermediate band photoconductivity School of Engineering: Electro-Optics and Photonics Poster - Graduate Research

STUDENTS Yining Liu ADVISORS Jay Mathews LOCATION, TIME Science Center 62, 3:00-3:15 Silicon is the basis for the electronics industry, but its high band gap and low efficiency of absorption in the infrared make it unsuitable for detecting wavelengths beyond 1100 nm. In order to induce infrared absorption below the band gap, an intermediate band can be formed between the valence and conduction bands by introducing deep level impurities at high concentrations. This so-called hyperdoped Si is fabricated by ion implantation and pulsed laser melting (II-PLM) which results in a supersaturated solution of the dopant in Si. Recent work on hyperdoping Si with Au or Ti has resulted in prototype infrared photodetectors that exhibit photoconductivity at wavelengths well below the band gap of Si. Although these results were promising, the efficiency of the detectors is very low. To achieve commercialized hyperdoped Si focal plane arrays, it is necessary to increase the detector efficiency. Efficient devices will require significant optical absorption in the material and high quality Ohmic contacts for carrier extraction. We fabricated Si layers hyperdoped with Au or Ti at varying concentrations, measured the optical absorption enhancement relative to Si, and attempted to form Ohmic contacts to the layers. The results show significant enhancement of optical absorption by increasing the implant dose. A prototype p-n photodetector was fabricated from Si:Au, but the efficiency was very low. One possible reason for this could be due to poor carrier extraction due to low quality contacts. For making Ohmic contacts to hyperdoped materials, we tried several treatments, including boron or phosphorus shallow doping, rapid thermal annealing of contacts, etching off the top metallic layer, and modifying the PLM process to suppress dopant segregation. Recipes for Ohmic contacts to each layer were demonstrated. These results indicate that the efficiency of a Si:Au photodetector could be significantly increased through a redesign of the device structure.

Maskless nanopatterning of non-volatile phase change material Ge2Sb2Te5 for opto-electronic applications School of Engineering: Electro-Optics and Photonics Oral Presentation - Graduate Research

STUDENTS Joshua Anthony Burrow ADVISORS Imad Agha, Andrew M Sarangan LOCATION, TIME Science Center 62, 3:15-3:30 Reconfigurable photonics has been at the forefront of modern optics research, especially as optics and electronics merge into true singledevice integration. Within that umbrella, we can identify a series of critical devices commonly used in free-space application such as spatial light modulators (SLMs), micromechanical adaptive beam steering mirrors and lenses. At the core, the physical idea remains the same: locally controlling the refractive index of the constituent material to affect the amplitude and phase of incident light. Critical issues common to many reconfigurable devices are bulkiness, low-speeds and large voltage requirements. However, phase change materials (PCMs) such as Ge2Sb2Te5 (GST) offer an alternative path for high-speed light modulation circumventing each of the aforementioned issues. In general, PCMs alter their inherent structural, electrical, thermal and optical properties via an electronic, optical or thermal stimulus, leading to a phase transition between a low refractive index amorphous state (index = 4.0) and high index crystalline state (index = 5.5). Due to these facts, GST has shown increasing interest among the science and engineering community, however additional developments are required to increase speeds and reduce power consumption of said platforms. One path towards advancing PCMs technologies and furthering our understanding of fundamental material properties is nanostructuring GST to sub-wavelength dimensions. An excellent candidate for fabricating nanometer sized structures is the oblique angle deposition (OAD) technique. In this work, we report on high-aspect ratio nanorod films of phase change material GST created via an OAD configuration using electron beam bombardment. We discuss structural properties exhibited by GST nanocolumnar films such as tilt angle of nanostructures, porosity and morphology which fosters the development of next generation free-space device. Various characterization methods will be presented including scanning electron microscopy and optical spectroscopy to understand light matter interaction at the nano-scale of an exotic chalcogenide phase change medium.

The security robustness of Modbus/TCP protocol in industrial control systems School of Engineering: Engineering Management, Systems, and Technology Poster - Graduate Research

251

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Hassan Ali Alsaad ADVISORS Mohammadjafar Esmaeili LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Since most of Industrial Control Systems (ICS) systems have been isolated from public networks, there have not been a colossal needs to secure them. However, in most of today's applications such as Experimental Physics and Industrial Control Systems (EPICS), Supervisory Control and Data Acquisition (SCADA), Distributed Control System (DCS) and Programmable Logic Controllers (PLCs) system are getting connected to the internet without paying attention to the security robustness of these devices. Industrial Control Systems (ICS) such as SCADA, DCS, PLCs are communicating with industrial equipment such as actuators, sensors, motors, and pumps using a special communication protocol called Modbus. For remote applications, multiple PLCs can be connected to each other to form a controlling network that uses Modbus / TCP communication protocol utilizing private/public networks. This research focuses on examining the security vulnerability of the Modbus/TCP protocol. To achieve this goal the researcher utilizes Modbus PLC simulator to simulate different cyber attacks through the local network. The cyber attacks have been formed using the MBTGET Perl script and Metasploit module, in Kali Linux penetration testing operating system. Our research shows some of the major security vulnerability in the Modbus/TCP protocol, which is one of the main communication protocols ICS system.

Fighting Hunger In Dayton Through Operations Research

School of Engineering: Engineering Management, Systems, and Technology Poster - Independent Research

STUDENTS Madeline Renee Mock ADVISORS Kellie R Schneider LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Many households are food insecure, meaning they lack access to a sufficient quantity of affordable and nutritious food. The Foodbank, located in Dayton, Ohio, is a private organization that works to combat food insecurity. The primary responsibility of the Foodbank is to serve as a central warehouse that collects, stores, and distributes nutritious food in the community. The goal of this project is to optimize the truck routes in order to reduce mileage and save operational cost for the Foodbank. This project focuses on the truck routes involving food collection. There are currently 51 active retailers that donate to the Foodbank regularly. These retailers are visited between 1 and 5 times per week, with many retailers receiving multiple visits per week. The Foodbank has 5 trucks that can run collection routes with each truck having a capacity of 10 pallets. The trucks are currently running 19 food collection routes per week totaling 967.28 miles. When the trucks are not being used for food collection, they can be used for mobile food pantries and deliveries to partner agencies. Therefore, The Foodbank is interested in reducing the number of food collection routes. This problem is formulated as a Vehicle Routing Problem. A spreadsheet solver that implements Large Neighborhood Search was used to create new routes. As a result, the number of routes was reduced to 17 per week and 707.32 miles per week. This 27% reduction in mileage results in a cost savings of 1,300 meals per week.

STUDENTS Wenhao Chen, Nicholas Michael Colwell, Yicheng Geng, Yuzhe Lin ADVISORS Mohammadjafar Esmaeili LOCATION, TIME Kennedy Union 312, 2:20-2:40 Abstract:The group plans to demonstrate how someone could hack a relatively unsecure network access point such as home network and use different tools to collect important personal data from the person being hacked. The group will do this by using 3-4 Raspberry Pis each running kali linux. The group will use a dictionary attack to continuously test multiple passwords to connect to the network. The group will use a variety of wordlists both custom and premade to accomplish this. After the group has hacked the network, the group plans on using Wireshark to collect email passwords and usernames from the data collected. The group hopes to demonstrate how someone could hack a home network and why it is important to properly secure your network.

In this project, a platform will be developed to provide a ground to explore the setup of the control system configuration.control system which could be represented as Programmable Logic Controller(PLC) which is an industrial control system which used to monitor the status of final control elements and make a decision based on the input it receives. Control system at the beginning applied to the industrial field by using a local network. The use of local network results in a network that has high potential to be secure from any vandalism. In addition, it makes IT engineer to have the ability to secure and control any instrument by just updating the infected or change that device. However, the need of a system that provide a secure area to be used for industries usages is increased due to the high growth in technology. ICS (industrial cyber security) provide an exchange of data in secure technique. Nowadays industries using a network that is connected to the internet which raises the risk of losing the exchanged data or increase the chance for a person who uses a computer to obtain unauthorized access to data. As a result, the project will focus more on the methods that could apply as protection technique that could be used to secure any exchange in data address by control system application. To achieve the goal several equipment and application used. A CPU which used to host all applications. A virtual box used to set both master (main PLC) and slave used as a SCADA control system.

STUDENTS Carter Douglas Spires ADVISORS Kelly Elizabeth Bohrer, Castel V Sweet LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Co-op Dayton is a non-profit organization that supports the development of communityand worker-owned cooperatives in the Dayton region, across industries but with a stronginterest in environmental sustainability. In partnership with the ETHOS and the Fitz Center, Carter Spires first interned with Co-op Dayton in the Spring of 2018 with the goal of researching potential “green” cooperatives for our region. It was found that southwest Ohio lacks commercial composting facilities and began to research the potential of developing one as a cooperative. Co-op Dayton spoke with several compost stakeholders and developed a partnership with a local compost social enterprise, GoZERO, which is interested in expanding in the Dayton region as a worker-owned cooperative. This Spring, Co-op Dayton has been connecting major employers and producers of food waste in the Dayton region that may be interested in the services of a compost cooperative, while developing proposals for both the governance and financial transition of GoZERO to the cooperative model.

Assessment of Tensegrity-Based Aircraft Wings Capable of Morphing School of Engineering: Mechanical and Aerospace Engineering Poster - Graduate Research

STUDENTS Austin Shelley Mills ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 This research involves a computational assessment of the strength and rigidity of tensegrity systems configured as aircraft wings, and comparison to conventional wing structures. Tensegrity systems consist of a series of compressed struts connected by tensioned cables that place the system in a self-equilibrium state. With all components being loaded axially, a tensegrity system has a potentially large strength-toweight ratio. Further, tensegrity systems are able to alter their shape by changing the length of the cables or struts, presenting the ability to function as morphing aircraft wings. Aircraft with wings that are able to alter their sweep, span, chord, and camber are particularly attractive for their ability change between high maneuverability to high lift to low drag configurations. Current work focuses on tensegrity wing topology optimization formulations.

Spatial Chains for Matching 3-Dinensional Curves 253

School of Engineering: Mechanical and Aerospace Engineering Poster - Graduate Research

STUDENTS Yucheng Li ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 9:00-10:15 This work introduces a methodology for designing a chain of three-dimensional bodies to match a set of arbitrary spatial curves. Three types of spatial bodies are defined to make this match: a rigid segment, a helical segment with constant curvature and torsion but varying length, and a growth segment that maintains its shape but may be scaled to become larger or smaller. The first two body types can be used to define mechanical chains that describe the kinematics of continuum robots, a rapidly emerging area of robotics. All three body types are used for morphometric analysis involving spatial land-mark curve matching. Beyond these applications, this work will more broadly impact machine design through its significant extensions to shape-changing rigid-body mechanism theory. In fact, the methodology for the spatial mechanical chains developed herein is an extension to planar shape-changing mechanism theory.

Studying Fluid Breakup and Dispersion to Predict Aerial Firefighting Ground Drop Patterns School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Graduate Research Goal 13: Climate Action STUDENTS Saad Qureshi ADVISORS Aaron Altman, Markus P Rumpfkeil LOCATION, TIME Kennedy Union 312, 9:00-9:20 This research was inspired by an article in Aerospace America, (June 2014), that showed resemblance in the ground patterns produced during aerial retardant delivery and von Karman vortex structures behind a bluff body. Retardant delivery ground patterns are described quantitatively by ground coverage level, which is the volume of fire retardant per area. Ground pattern and associated coverage level prediction quickly becomes a highly complex task when the number of potential dependent variables is considered. The United States Department of Agriculture â&#x20AC;&#x201C; Forest Service, (USDA-FS), has listed 14 potential factors believed to have some influence on the ground coverage and associated patterns. Influencing factors range from the easily measured such as speed and volume flow rate to factors more unique to each aircraft such as tank exit geometry and arrangement. Experimentally, the problem has not been studied in much detail and numerical models that predict ground patterns are few. The cycle time to obtain results from numerical models is slower than the USDAFS requires in order to have a real-time impact on planning to influence a reduction in risks to fire crews and fire damage to structures. The complexity of the problem finds its origins in the nature of the interactions of the fluid column as it exits the aircraft. Apart from the factors controlling the breakup of the fluid, the fluid column that vortices are being shed from, in addition to being constantly deformed under the shear of the wind is also a victim of Kelvin-Helmholtz and Rayleigh-Taylor wave instabilities. This vortex pattern is posited to have a first order effect on the shape of the ground patterns. A set of experiments were conducted at the University of Dayton â&#x20AC;&#x201C; Low Speed Wind Tunnel, (UDLSWT), which simulated the drops for aerial tankers. Much effort was spent in capturing and quantifying the breakup process in a relatively low Reynolds number flow. The primary breakup of the fluid column and subsequent secondary breakup of particles emanating from the primary fluid column are the key culprits in ground pattern determination. Particle Shadowgraph imagery was utilized to study the breakup process. Frequency analysis was performed on the water jet boundaries the results of which showed that the frequency was an order of magnitude higher at the location where the structures resulting in breakup of the water jet/parent column originate in comparison to the rest of the jet extremities. Furthermore, the frequency amplitude was even higher at the location where the structures created breaks off from the parent column and creates smaller droplets. The location where the jet breaks off is also quantified in terms of the jet speed, air speed and jet diameter. All these results, along with the prospective results from the current ongoing research will be used to form a ground coverage predictive tool which will be useable by the wildland firefighting crews in order to quickly assess and control wildfires by fire retardant aerial application.

Analyzing the Use of Laser Light Visual Feedback for Stepping Task in Stroke and Multiple Sclerosis Populations School of Engineering: Mechanical and Aerospace Engineering IAC Student Tech Symposium Oral Presentation - Independent Research

STUDENTS Kevin Michael Nowacki ADVISORS Kim E Bigelow, Kurt J Jackson, Megan E Reissman LOCATION, TIME Kettering Labs 204, 9:40-10:00 Movement disorders of the lower extremities are common for many individuals who have experienced various neurological conditions including stroke, multiple sclerosis, anoxic brain injury, and spinal cord injury. Research has suggested that visual or audio cues can help

254

improve mobility for these individuals. There have been multiple studies showing increase in mobility or motor control function after receiving corrective visual feedback during rehabilitation or training.Recently a wearable laser light system that provides real-time visible feedback on movements has emerged as a commercially available rehabilitation tool; however, research examining the use of lasers for visual feedback has been more limited. Research examining the use of lasers has been limited, though what has been done has shown promise for future research. Wearing a laser that is carefully positioned on the body can provide feedback about the movement trajectory on a nearby wall. An individual can then observe if their movement strategy results in a path that would be desirable for reducing extraneous movement, ensuring better weight distribution, and improvement of overall movement efficiency. Such a system could be ideal for at-home training, especially if using target lines. The purpose of our study is to determine if the use of a limb mounted laser during leg raises can reduce pathologic frontal plane motion and result in a more desirable lower limb motion. Specifically, our team is interested to determine if participants can make improvements when a laser is used compared to baseline (no feedback) movements. With the laser feedback, we predict the participants will have increased knee and hip flexion, decreased hip abduction and circumduction, and decreased extraneous frontal plane movement of the knee joint center.

Towards a Pre-Processing Algorithm for Automated Arrhythmia Detection School of Engineering: Mechanical and Aerospace Engineering Poster - Honors Thesis

Goal 3: Good Health and Well-Being STUDENTS Sarah Miller ADVISORS Timothy Reissman LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 There are a variety of different wearable fitness/cardiac monitoring devices that are currently used in many peopleâ&#x20AC;&#x2122;s day to day life. The primary cardiac function of these devices is to monitor heart rate, however we believe that they could be utilized to detect different forms of arrhythmia. In order to categorize and identify different forms of arrhythmia, we are utilizing published EKG data sets from existing databases as a basis for machine learning. The challenge that comes from the existing data sets is that the format they present the data in does not lend itself to machine learning, which requires data to be in a vector. This makes the process of converting the existing data sets into workable vectors long and tedious. Therefore, we are working to develop an algorithm that will be able to vectorize the data from multiple different data sets so we, and anyone who wishes to use machine learning on these signals, are able to quickly and accurately use now workable, prior data sets.

STUDENTS Andy Lee Bazler, Bennett Clark Snyder ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 10:45-12:00 The goal of this research is to design, build, and test new pedaling mechanisms to be incorporated into a bicycle-like devices for spinal-cord injured individuals. Many challenges arise in pedaling capability of a paraplegic or tetraplegic patient that are very different from a healthy individual. The intended tricycle users mainly employ Functional Electrical Stimulation (FES) to produce quadricep contractions, which are converted into a propelling force. Various concepts for alternative mechanisms have been produced. Pedaling force and motion simulation models were generated to evaluate the concepts. The desired pedaling mechanism must overcome dead-points encountered during the pedaling cycle while optimizing the transmission of power. Thus, the goal is to convert the modest amount of power generated by FESstimulated legs into cycling power for a tricycle.

The Perception of Student Bias from Engineering Faculty in Higher Education School of Engineering: Mechanical and Aerospace Engineering Oral Presentation - Graduate Research Goal 10: Reduced Inequalities Goal 4: Quality Education STUDENTS Kyra Elizabeth Twohy ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union 310, 11:20-11:40 This study investigated the engineering faculty perceptions of student bias in a variety of classroom settings, specifically from the point of view of both male and female students. The goal was to show perceived differences between how male and female students rate professors. This is especially relevant as teaching evaluations are a crucial part of tenure and promotion cases. The study used a survey comprised of 25 questions that assessed the level of positive and negative bias for male and female students when evaluating teaching. Forty-eight faculty members from the engineering department of a midwestern university completed the survey. There was also an interview that asked 8 questions about the facultyâ&#x20AC;&#x2122;s experience with bias and gender bias. Of the forty-eight faculty members who completed the survey, 10 were interviewed. Data from the survey was analyzed using one-way ANOVA tests, as well as descriptive statistics. Qualitative data was obtained from the coded interviews. Results showed that the facultyâ&#x20AC;&#x2122;s perceptions positioned male students as more positively biased when evaluating male faculty and were more negatively biased towards female faculty, than their female counterparts. Class size also was found to contribute to bias, as class size increases led to increasing perceived negative bias. This study finds that more research should be done to establish a method of removing bias from teaching evaluations, so that course evaluations only reflect teaching ability.

The trials measure the center of pressure in the Anterior-Posterior and Medial-Lateral directions by a force measuring platform. The average sway range in both directions, as well as mean velocity of the center of pressure were calculated. Results found that shoes on and feet flat on the floor decreased average sway ranges (90.6 mm vs. 38.1 mm), though an interaction between shoes and foot contact was found. Our findings led to a recommendation that older adults wishing to maximize stability have shoes on, and feet flat on the floor when reaching into cabinets.

reach of such programs to low-income communities. Reducing household energy consumption would be extremely beneficial as it would lower utility bills for low-income households who spend a substantially greater portion of their income on energy bills compared to other households. While installation of energy efficient appliances is a dominant component in energy reduction, adopting energy behavior has the potential for significant savings. Research is being conducted to determine the most effective techniques necessary to successfully promote and enact energy reduction behaviors in low-income communities based upon peer-to-peer methods. Through a program that will track and analyze thermostat and consumption (energy and water) data in a low-income neighborhood in Dayton, behavioral models will be designed and implemented to deduce what education and intervention methods produce optimal energy behavior results, how demographics impact energy behaviors, and what factors most strongly correlate to an increase or decrease in energy consumption.

Wing Performance Changes Due to Wing Surface Contours School of Engineering: Mechanical and Aerospace Engineering Poster - Honors Thesis

Goal 9: Industry, Innovation, and Infrastructure STUDENTS Faith Alison Loughnane, Rachael Marie Supina ADVISORS Sid Gunasekaran LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Most leading-edge tubercles studies (inspired from the humpback whale) involve serrated-type leading edges where the airfoil cross-section is destroyed. In this research, the effect of the tubercles is investigated where the airfoil cross-section is preserved along the span of the wing. By maintaining the same airfoil section throughout, reducing the chord reduces the thickness of the wing, creating uneven wing surface contours. These contours are hypothesized to affect the spanwise flow thereby affecting the induced drag, roll-up of the wingtip vortex, and the parasite drag of the wing. Sensitivity study was done on the number of contours along the span (6, 9 and 12) and contour location (leading edge, trailing edge, both leading and trailing edge) by performing force-based experiments at the University of Dayton Low Speed Wind Tunnel (UD-LSWT). The aerodynamic coefficients were compared among the wing with and without contours. The aerodynamic lift and drag coefficients along with variations in aerodynamic efficiency will be presented for wings with and without contours.

Aerodynamic Feasibility Study on Highly Distributed Lifting Configurations for Aircraft School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

STUDENTS Michael Mongin ADVISORS Aaron Altman, Sid Gunasekaran LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 Preliminary experimental results showed that a highly distributed lift system (200 mini-wings) generated approximately 45% of the lift of the conventional mono-wing of equal wing area and equivalent aspect ratio. This performance was shockingly good given the penalty associated with the subscale Reynolds numbers under consideration. Hence, improvement in aerodynamic efficiency of the distributed lift configuration would be expected when scaled up to a General Aviation aircraft class scale. Taken in combination with the potential dramatic savings in wing weight, these preliminary results were considered sufficient justification to examine the concept more deeply. This paper will include the promising results of a parametric study performed using a Vortex Lattice Technique and compares those numerical results to experimental results. The results continue to suggest the possibility that the distributed lift configuration may have a practical niche when operational constraints are taken into consideration with some multi-wing configurations obtaining upwards of 60% of the lift of the equivalent monowing configuration.

Design Modeling of Various CubeSat Solar Arrays Configurations School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

STUDENTS Dillon Montgomery Balk, Ben Markus Millard ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 As technology has developed over the years, small form-factor satellites known as CubeSats have been able to replace much larger and conventional earth satellites. Solar arrays are placed on the outside of the CubeSat to generate power for their mission. In order to increase the performance and energy absorption of the CubeSat, the solar array can be configured to deploy and move to track the sun as the satellite moves in its orbit. This research project involves design modeling of various mechanisms configurations to achieve this increase in performance and efficiency, while minimizing the complexity and thus weight of such a mechanism. The three mechanisms explored involve one with a single vertical axis of rotation, one with a single horizontal axis of rotation and a third with a universal type joint for two degrees

Xsens Distance and Displacement Accuracy in Human Motion School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

STUDENTS Julie A Buynacek ADVISORS Kim E Bigelow LOCATION, TIME Kennedy Union Ballroom, 1:15-2:30 The Xsens MVN Awinda tracks human movement with 18 wireless sensors placed in specific places on the body as well as a prop. The system allows for real-time 3D visualization of motion and measures the distance and displacement of tracked motion. It is hypothesized that Xsens data would be most reliable when walking, less reliable when jogging due to greater disturbed motion, and least reliable when using crutches. Disturbed motion is greater movement that could contribute to displacement of the sensor from its original position.

Nominally, NinjaFlex is capable of elongations greater than 650%, making it appealing for load-bearing biomedical, automotive, and aerospace applications requiring large elastic deformations and extreme stretchability. ASTM D412 tensile test specimens are 3D printed using a Josef Prusa I3 MK3 FDM printer (under different processing conditions) and mechanically tested using an Instron 3365 long-travel load frame. Several common hyperelastic material models (e.g., neo Hookean, Mooney-Rivlin, Yeoh, Ogden, Arruda-Boyce) are calibrated to the mechanical test data and implemented into the commercial finite-element software Abaqus. Preliminary finite-element simulations are conducted on a 3D-printed NinjaFlex prosthetic finger geometry to quantify the impact of manufacturing process parameters on prosthetic performance.

Goal 11: Sustainable Cities and Communities Goal 7: Affordable and Clean Energy STUDENTS Sam Powell Dasco, Theresa Isemann, Colin Joern, Melissa M Padera ADVISORS Kevin P Hallinan LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 RE-volv is a national non-profit whose mission is to empower communities to learn about and afford renewable energy. Empowerment has become a buzzword in today's society; what does empowerment look like on a practical level? This poster will explore the methodology in which college students were empowered to organize one of the inaugural chapters of RE-volv and successfully raise over $32,000 for a Dayton non-profit to offset 100% of their electricity use. Students did this while educating over 400 campus and community members about solar energy. Successes and failures, motivations of internal and external partners, and the overall crowdfunding process will be explained in order to define what empowerment looked like for these students.

Goal 13: Climate Action Goal 12: Responsible Consumption and Production STUDENTS Travis C Meyer ADVISORS Joshua S Heyne LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 Since the late 19th century, Earth’s average temperature has risen approximately 1.62 degrees Fahrenheit. This is in part due to an overall increase in the concentration of carbon dioxide and other heat-trapping emissions in the atmosphere. If the level of emissions continues to rise at the current rate, we will continue to see the detrimental effects including rising sea levels, an increase in forest fires, and ocean acidification impacting ecosystems and human civilization. As an attempt to mitigate the effects of climate change, the aviation industry is looking towards alternative jet fuels (non-petroleum derived fuels) as a solution. Programs such as the National Jet Fuel Combustion Program (NJFCP) and JET Program are working to improve the commercialization of these alternative jet fuels. Fuel property research would aid NJFCP and JET in accomplishing their missions by increasing their understanding of figures of merit (FOM) in fuel performance, namely lean blowout, high-altitude relight, and cold start ignition due to the fuel properties. Data mining fuel properties such as viscosity and surface tension within a specific temperature range allows these programs to better understand the FOM of the fuel. Ideally, this work would reduce carbon-foot print, support surrogate development, and improve commercialization of alternative jet fuels.

Linkages In Mechanical Presses That Produce Substantial Dwell School of Engineering: Mechanical and Aerospace Engineering

Poster - Independent Research STUDENTS Matt Owen Deters, Zack James Jordan ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 A mechanical press is a common manufacturing machine that is used to form and cut sheet metal. Presses can use mechanical, hydraulic, or pneumatic power to delivering a force over the stroke of the machine. The benefit of mechanical presses is the high stroking rate that can be achieved with low energy input while in use. Mechanical presses use a flywheel to store energy and a series of linkages to convert rotational motion into linear motion. Some forming operations like coining and squeezing benefit from a dwell at the bottom of the stroke, a position commonly referred to as bottom dead center (BDC). This research explores models for different mechanical systems that obtain this desired dwell. The designs presented include variations of a knuckle joint press mechanism and variations of a geared five bar with connecting rod and sliding output. Each of the mechanisms is being developed as a solid model and animation to assess the viability of the proposed designs.

Tracking the Center of Mass of a Human Using a Statically Equivalent Serial Chain School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

STUDENTS Ian R Melnyk, Alex James Seither ADVISORS Andrew P Murray, Dave Harry Myszka LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 This project seeks to validate the use of a statically equivalent serial chain (SESC) in locating and tracking a human’s center of mass (CoM). The statically equivalent serial chain used in this project is comprised of 13 parameters, each roughly corresponding to a portion of the human body. Given these 13 parameters, the SESC points directly at a person’s CoM. Every individual has a unique set parameters to calculate their SESC. These parameters are determined by capturing poses and using the body segment length and position information, as well as the center of pressure reading, acquired from the different poses. A Wii Balance Board and Xbox Kinect were used in this study as inexpensive force plate and motion capture systems. There are other methods for calculating a person’s center of mass, but these require expensive equipment and more complex computational processes. The method proposed here is a low cost, fast, and easy way to accurately predict a person’s CoM. In order to determine the feasibility of the SESC model, we constructed a PVC and steel human model. This way, the weights for each part of the body could be known to validate the accuracy and repeatability of the program. A minimum number of poses required to achieve an accurate CoM prediction was determined by figuring out where human model’s parameters converged, which increases time efficiency of the process. Thus, validating the SESC method as a fast, easy, and fairly accurate solution for predicting a human’s CoM.

Design and Verification of an Autonomous Gait Monitoring Device School of Engineering: Mechanical and Aerospace Engineering Poster - Independent Research

STUDENTS Sydney Marie Lundell ADVISORS Megan E Reissman, Timothy Reissman LOCATION, TIME Kennedy Union Ballroom, 3:00-4:15 The prime method of analyzing gait cycles with balance aiding devices has been typically restricted to laboratory controlled environments, where motion capture software or visual observation are available. Few methods for real-world gait analysis exist that do not require active human monitoring. We are bridging that gap by developing an autonomous device which attaches to a cane, or cane like device, to record gait speed, frequency, and applied load. To date we have successfully verified the canes accuracy and are collecting experimental data.

educational strategies is teaching literacy and Science, Technology, Engineering and Mathematics (STEM) in a highly integrative manner (Sterling, 2014; Cervetti, Pearson, Bravo, & Barber, 2006; National Academy of Engineering, 2008; Cervetti, Barber, Dorph, Pearson, & Goldschmidt, 2012; Padilla, Muth, & Padilla, 1991; Guthrie & Ozgungor, 2002; Palincsar, & Magnusson, 2001; Romance & Vitale, 2001; Campaign for Third Grade Level Reading, 2016). To address this issue, the STEM Stories project provided innovative, engaging, fun and highly integrated STEM and Literacy curriculum that was facilitated by undergraduate engineering and teacher education students to second and third grade students at three local schools: Fairview, Kiser and Ruskins.The activity modules were developed using research based best practices for attracting underrepresented students to STEM, to show how STEM can make a difference and impact peopleâ&#x20AC;&#x2122;s lives and to incorporate culturally relevant literature and targeted literacy activities (National Academy of Engineering, 2008). The activity modules were facilitated at three schools in the Dayton area. Throughout the experience, we were able to see the impact that facilitating the modules had on the development of the second and third grade students. Participants in the program expanded their writing abilities from less than a sentence to full paragraphs and pages. Participants in the program were also able to learn to engage with the engineering design process while further developing math, science, and writing skills. We were able to gain experience leading a classroom and actively engaging with elementary school students.

Goal 7: Affordable and Clean Energy STUDENTS Ashish Gogia ADVISORS Vikram Krishna Kuppa LOCATION, TIME Kennedy Union 211, 1:40-2:00 Polymeric systems are modified routinely by addition of inorganic nanoparticles for enhanced properties and functionality. Such nanocomposites may contain fillers of varying miscibility, such as carbon black, silica, metal oxide, pigments, and /or various combinations thereof. However, on main impediment in the development of high-performance polymer nanocomposites (PNCs) are to realize a good dispersion of nanoparticles, owing to the strong interparticle interactions and weak polymer-nanoparticle interfacial interactions. Hence, the state of dispersion of the polymers and fillers is crucial to the behavior of polymer nanocomposites. To address this issue, in this research, we perform Dissipative Particle Dynamics (DPD) simulation of these blends, varying polymer-polymer, filler-filler and polymer-filler interaction energy, to understand the hierarchical structure and dispersion over multiple length and time-scales. In addition, the simulation results are also validated experimentally through small angle x-ray scattering data to provide insight and understanding of how these complex structures develops in these multicomponent systems.
