Nonprofit finds evidence of police misconduct By Aradhna Madireddi The Chronicle
The Durham Police Department has come under fire from the Southern Coalition for Social Justice and Durham Fostering Alternatives to Drug Enforcement Coalition following claims of racial profiling and unethically paying informants. The SCSJ and Durham FADE Coalition have unearthed evidence that the DPD pays unconstitutional conviction bonuses to undercover informants in drug cases, creates license checkpoints for drug interdiction and uses federal grant money to fund undercover marijuana buys in black neighborhoods. Assistant Chief of Police Jon Peter denied the accusations that the department racially profiles drug arrests after two attorneys produced documents that marijuana arrests have increased 70 percent since Police Chief Jose Lopez took office, with the vast majority of those arrested being black. “Durham really stood out like a sore thumb. It had one of the largest racial disparities in the state, with respect to African American drivers,” said Ian Mance, a Soros Justice Fellow and civil rights attorney from SCSJ who created the report. He noted that SCSJ uploaded search

Duke engineers have created the world’s first three-dimensional acoustic cloaking device, an innovation that distorts sound waves to give the impression an object is not present. University researchers in the electrical and computer engineering departments set out to discover how they could best manipulate sound. The device is the first of its kind able to acoustically cloak sound coming from any direction and researchers are considering various applications for the object. To make this technology possible, Steve Cummer, professor of electrical and computer engineering, said two goals had to be met—the device needed to absorb all waves in contact with it and not cast an acoustical shadow from the absence of sound waves. “This is totally fundamental research,” Cummer said. “We’re not aiming this at any particular application, we’re just trying to show the kinds of things that can be done.” Although this device is the first of its kind, Bogdan Popa, a research scientist in electrical and computer engineering, noted that the Amanda brumwell/The Chronicle

DSG hears presentations on tuition, library renovations By Hayley Trainer The Chronicle

Two administrators spoke to DSG members Wednesday evening about tuition at Duke.
Provost Peter Lange and Executive Vice Provost for Finance and Administration James Roberts addressed the Duke Student Government senate Wednesday night about tuition and affordability. The discussion followed the Board of Trustees’ approval of a 3.9 percent increase in undergraduate tuition for the 2014-15 academic year. Lange said that each dean of the University’s schools takes several factors into consideration when determining tuition rates, such as programmatic needs, affordability, market
factors and alternative revenue sources. Each dean then uses these factors to individually determine their school’s tuition. Lange noted that Duke’s tuition and its annual increase are comparable with those of peer universities. Several of Duke’s peer institutions have also raised tuition for the 2014-15 academic year. Stanford University’s Board of Trustees approved a 3.5 percent increase, the University of Pennsylvania’s board approved a 3.9 percent increase and Dartmouth’s board approved a 2.9 percent increase. Lange noted that student tuition goes
toward supporting many factors to enhance the student experience, including more than 60 undergraduate majors, 23 languages taught, and the University’s 8:1 student-to-faculty ratio. “Most of our peers are around 7 or 8 to 1 [student-to-faculty ratio],” Lange said. “In the past few years, we’ve been doing a lot more things that utilize the small student to faculty ratio, like senior theses.” Although 53 percent of undergraduates paid full costs of attendance in the 2012-2013 academic year, the University’s See dsg, page 6
