Enriching education through discovery

Saving lives with innovative sensors 融合不同學科知識研發智能監測系統

Leadership and new thinking in an inter-disciplinary world 跨學科世界需要的領導才能與新思維

From the Editor The single discipline approach to studying the plurality of problems confronting our fragile planet today is no longer considered broad or flexible enough to deliver much-needed solutions and insight. Today the most interesting challenges tend to lie in inter-disciplinary areas where projects draw on the skills and knowledge of a wide crosssection of scholars. In this issue of CityU Today, we look at several inter-disciplinary projects and initiatives viewed through the overarching new curricular focus on discovery and innovation. As set out in our latest Academic Development Proposal, this unique feature of our curriculum promises to offer students and academic staff fresh impetus to strive for excellence in professional education and problem-driven research. We also have reports on innovative advances in building safety, our regular books section and an update on technology developed for libraries. Happy reading! 時至今日，脆弱的地球面臨着各種複雜多元的問題，單一的學科研究方式已被視為視野狹窄、有欠靈活，難以產生迫切需要的解決方案與真知灼見。今天，最有意義的挑戰多半來自跨學科領域。此類研究課題凝聚了範圍廣闊的跨學科學者的技能與知識。在本期《今日城大》中，我們透過新設置的探索為本創新課程，探討幾個跨學科的課題和舉措。正如近期公布的「學術發展計劃書」所言，城大課程的新特色將為師生提供新的動力，在專業教育與「問題導向」研究中追求卓越，再建新功。本期還報道了建築安全的創新進展，並包含定期的「新書推介」以及城大圖書館應用新技術的情況。祝各位閱讀愉快！

封面故事 The Academic Development Proposal (ADP) 2012–2015 acts as a blueprint for an entire three-year period. It sets in motion new initiatives and fresh impulses aimed at carrying the campus towards the ultimate goal of achieving excellence in research and professional education, as described in our Strategic Plan. It is an opportunity for the whole University to reflect on fundamental aspects of our overall strategy, teaching and learning issues, advanced scholarship, and community linkages. CityU Today caught up with Professor Arthur Ellis, Provost, the member of the senior management team responsible for shepherding the ADP.

innovation, an inter-disciplinary research area, or both. Why is there such a strong focus on interdisciplinary approaches in the ADP? Inter-disciplinarity, or cross-disciplinarity, is now a global trend in scholarship and, correspondingly, in higher education. Increasingly we are finding that interesting problems, many of which are of great importance to society, tend to cut across traditional disciplines. We can see this in areas such as energy and environment that need experts with a range of, for example, science, technology, law and social science backgrounds. An IPDA could fund a GE course in climate change or one in stem cell research or environmental policy where a whole set of concepts, ideas and issues from different traditional disciplines are embedded.

“This course challenges students to think anew about the psychological expressions of the human mind within various cultural contexts. It engages them in a critical discussion of literary representations of madness and mental illness from historical, cross-cultural and inter-disciplinary perspectives,” Dr Linder said. Another example is “Science, Fiction and the Supernatural” taught by two faculty from the Department of Biology and Chemistry (BCH), one from the Department of Building and Construction, and one from the Department of English. “We offer students an inter-disciplinary opportunity to explore and compare two approaches of knowing—scientific knowing

城大提交給大學教育資助委員會的「2012–2015學術發展規劃」(ADP)是未來三年的發展藍圖。該規劃為構思的新措施、新想法注入新動力，將引領城大發展成為學術研究卓越、專業教育出眾的高等學府，而這恰恰是城大「策略性發展計劃」的宗旨。城大將把握契機，通盤思考整體發展策略、教學問題、高層次的學術研究、與社區的聯繫等大政方針。《今日城大》就此採訪了負責ADP的城大管理層成員、學務副校長Arthur Ellis教授。在新的ADP中，「探索」將起到甚麽樣的作用？

深度。另外，我們在思考全球化和科技技術給世界帶來急劇變化的同時，亦將視此為重新討論如何規劃高等教育的契機。請問會採用甚麽機制營造探索創新文化？我們已經設立了「跨學科專業發展獎」計劃，為城大的全職學術及教學人員提供「校內學術休假」，讓他們有時間、空間和資源去制定尖端跨學科研究計劃，或者設計強調發現與創新的特色通才教育科目，兩者也可同時進行。我們希望通才教育課程能真正激勵學生、啟迪學生，成為城大創意引擎的一部分。不同學術部門的人可以組成一個小組，申請學術休假時間、共處的空間，以及其他資源，共同設計強調發現與創新的跨學科通才教育科目，或從事某一跨學科領域的研究；亦可兩者兼做。為甚麽如此注重跨學科教學與研究？跨學科已成為全球學術研究及高等教育的大趨勢。我們發現，愈來愈多有意思的問題都會橫跨多個傳統學科，其中很多對社會來說極其重要。舉個例子，在能源和環境等領域，我們可能需要多個學科背景的專家，如具有科技、法律和社會科學背景的專才。「跨學科專業發展獎」可以用來資助氣候變化、幹細胞研究或環境政策通才教育科目，這些科目融入一整套不同傳統學科的概念、創意和議題。大學教育資助委員會（教資會）已經開始向跨學科投入大量資源，撥款資助主題研究團隊。

應勢推廣跨學科學習在新的四年本科學制中，學生修讀的很多通才教育課程都具有很強的跨學科特色。以下兩個例子可資證明。中文、翻譯及語言學系助理教授彭吉蒂博士開設了一門「瘋狂與文學」的通才教育科目。修讀該科目的學生可以從多個角度討論精神疾病的各種觀念，涵蓋生理學、心理分析、靈性、歷史、社會學等多個領域。彭吉蒂博士說：「這門課程旨在要求學生在多種文化語境中，重新思考人類思維的心理表現方式，讓學生從歷史、跨文化與跨學科視角，對瘋癲與精神疾病的文學表現做批判性的討論。」另一門跨學科通才教育科目叫作「自然科學、科幻小說和超自然現象」，授課教員有四位，兩位來自生物及化學系，一位來自建築系，一位來自英文系。統籌開設這一科目的生物及化學系副教授江潤章博士（左）說：「設立這個科目的目的是為學生提供跨學科學習的機會，探索和比較兩種認知方法—— 一種是科學認知法，一種是敘事認知法，並且研究它們對社會的影響。」修讀該科目的學生可以探究下述知識要點：科學的調查方法、對現實與真理的感知、情緒生物學、平衡心態的方法。他們將研究科學哲學、陰陽、不明飛行物體、神話學、時間旅行、啟示文學等。

政府、非政府組織和本港商界等社群夥伴對此類團隊工作獲得的成果通常很感興趣。我們將通過聯合聘請僱員的新計劃，為成立這類團隊提供便利，即由幾個學術部門聯合聘任教員，例如，聘請某位學者到城大任教，六成資源可能由能源及環境學院負責，其餘四成由公共及社會行政學系負責。這位學者則會同時擔負兩個學術部門的教學、研究和服務工作。

Measuring the quality of power 測量電能質量有新招 By Ellen Chan

文：陳倩茹

Imagine for one moment the multitude of electronic devices at work every day in someone’s flat or office. Keeping tabs on the power supply needed would be virtually impossible without the smart metering systems commonly used in Hong Kong. These systems provide a fast, reliable and costeffective solution to demand-side management.

二O一一年五月

專業教育與研究 But while smart meters can easily measure power consumption for monitoring and billing purposes, they cannot detect power quality. That is, they don’t provide information on voltage, current, total harmonic distortion as well as individual harmonics, compatibility between power devices and waveforms for event reporting. But measuring power quality is as important as calculating consumption, according to Dr Norman Tse Chung-fai, Senior Lecturer in the Division of Building Science and Technology. “Equipment that has not been properly designed to cope with a disturbance

prohibitive for most building projects. In view of the proliferation of smart meters and other devices for saving energy, though, the challenge is to lower costs and improve accessibility to information. One promising development has been initiated by Dr Tse and Dr Ricky

城大建築科技學部高級講師謝松輝博士表示，電能質量涉及電壓、電流、頻率與運作中電力設備之間的兼容性。「發生電力干擾時，若有關設備並未附有適當設計以適應此類供電情況，該設備便可能無法如常運作，」謝博士說。

Lau Wing-hong, Associate Professor in the Department of Electronic Engineering. Together they have developed a novel cost-effective algorithm for analysing power quality. Their method collects information on timevariant electrical power signal for instant analysis by measuring basic power and harmonic data on commercial micro-controller units, Dr Tse explained. “The algorithm can measure power consumption and display the disturbance of power quality on smart meters. In addition, it can transmit highly-compressed data on voltage and current waveform to a remote central management system for storage and further analysis,” Dr Tse said, adding he has filed for a US patent for the algorithm. The data transmitted helps engineers perform prompt analysis in the event of a power failure. Dr Tse said the new algorithm can be applied to low-cost smart meters. A prototype sponsored by the Hong Kong Applied Science and Technology Research Institute has been constructed and tested by scientists at CityU, and some corporations have already expressed an interest in applying the technology to the commercial production of monitoring devices. The prototype won the outstanding product award at the China Hi-Tech Fair a few months ago. “The algorithm can help build a micro-grid system that can improve energy efficiency in the future,” Dr Tse said.

目前普遍使用的智慧型電錶系統，主要由基本能量錶和專用網絡組成，能夠提供快速、可靠且經濟實惠的電力需求管理方案。智慧型電錶一般測量電度值，並監控能量和計算賬目，但不會測量電能質量，而能夠測量電能、電壓、電流、功率系數及諧波失真並能為事故報告提供獨立諧波和波形計算等信息的電能質量監控電錶，卻又安裝成本高昂，未能普遍應用在建築物主要電路和設備中。為此，謝博士與電子工程學系副教授劉永康博士研究出一種新型低成本智慧型電錶電能質量分析算法。這種算法能用於市場上的微控制裝置，並能測量基本功率和諧波信息，還可提供隨時間變化的功率信號，便於瞬時分析。「這種算法的特點是，除了可以計算功率和顯示電能質量干擾外，還可以向智慧型電錶系統的遠程中央管理系統傳輸高度壓縮的電壓和電流波形，以便儲存和作進一步分析，」謝博士說。他表示已為這種算法在美國申請專利。出現電力供應事故時，這些數據便於工程師及時作出分析。謝博士表示，這種新算法適用於低成本智慧型電錶。目前，執行新型電能質量分析算法的原型電錶已經由香港應用科技研究院贊助製成，並通過測試，及於中國國際高新技術成果交易會獲獎，多家公司有興趣將這項技術付諸應用，生產相關的監控設備。「這種算法有利於將來建設微電網系統，改進能源效益，」謝博士說。

Check out new tech for libraries 新電子系統優化圖書館服務

By Michael Gibb

文：鄭智友

One of the most labour-intensive jobs in a library is checking out books and restocking shelves. Both tasks tie up staff for long periods during the work day, preventing them from doing other duties, such as cataloging new materials, assisting academic staff and students with research, or working on technical support. A solution to the perennial problem of processing individual library items has been under investigation for at least a decade: using radio-frequency identification (RFID) to tag books. RFID has many applications, especially in supply chain management to check inventory lists, and the benefits are manifold compared to the barcode technology that dominates logistics today, especially for libraries. One of the biggest advantages over barcode technology is checking out books. RFID can “read” a pile of books in a single operation whereas barcode technology necessitates a librarian, or automatic scanner if available, handling each item individually. Another major plus is RFID has memory capability, which means librarians can look for books that have been misshelved, an otherwise impossible task in a library stacked with hundreds of thousands of publications. “Technology has evolved at an incredible rate in the past decade. It changes the way librarians serve their patrons and perform their work,” says Professor Steve Ching Hsianghoo, University Librarian at CityU. But, as Professor Ching explains, technology is just a means to an end. “The choice of technology is an important decision because it is the selection of a service transformation tool that is supposed to bring about benefits and improvements.”

The key issue now is what kind of RFID is most suitable for libraries. “When libraries started to use RFID, HF [high frequency] was the only available technology and thus naturally became the de facto choice by the system suppliers at that time,” Professor Ching explains.

An alternative is ultra-high frequency (UHF) “UHF RFID is definitely gaining more attention in recent years and has been widely deployed in the logistics and retail industry. Many big companies, such as Wal-Mart, Metro, Marks & Spencer, are using UHF RFID at their retail outlets,” Professor Ching says. Another example is Hong Kong International Airport, the world’s first

Professional Education & Research 在處理圖書出借方面，RFID較條碼技術尤佔優勢，只要操作RFID一次，即可「讀入」一疊圖書；而用條碼技術，一名圖書館員或一台自動掃描儀（如有的話）須每次逐本單獨處理。RFID的另外一大優點是具備存儲能力，圖書館員可藉此尋找上錯架的圖書。在藏書量數十萬冊的圖書館內，以前這是無法辦到的事。「過去十幾年裏，技術發展一日千里。圖書館員的服務和工作方式全都改變了，」城大圖書館館長景祥祜教授說。不過景教授表示，技術只是達到目的的手段而已。「選擇哪項技術是一個重要決定，因為這意味着選擇改換服務的工具，並期望藉此得益及提高效率。」

辦理借書手續和圖書重新上架是圖書館最繁重的工作之一。這兩項工作佔用圖書館職員很多時間，剩下做其他工作的時間就少了，例如給新文獻編目、幫助教學人員與學生做研究或提供技術支援等。處理圖書出借工作反覆發生，圖書館十多年前開始，就考量如何利用無線射頻識別技術（RFID）解決這個問題。

甚麼類型的RFID最適合圖書館呢？這個問題很重要。「圖書館開始使用 RFID 時，只有高頻技術，因此系統供應商當時理所當然地選擇了高頻 RFID，」景教授解釋說。

另一選擇則是超高頻RFID 景教授說：「近年來，超高頻RFID日益受到關注，已經廣泛應用於物流業和零售業。沃爾瑪、麥德龍、馬莎等大型公司都會在其零售店使用超高頻RFID。」

RFID應用廣泛，特別是在供應鏈管理行業中，主要用來清查庫存。與目前物流業佔主流的條碼技術相比，RFID具有更多優點，對圖書館而言更是如此。

香港國際機場則是另一個例子，在全球率先全方位使用端到端超高頻 RFID行李處理系統。

It’s now generally accepted that a person’s career-path is likely to be diverse; the rarity— not the norm—is to hold a job for 40+ years until retirement. The choices for overseas education, holidays and employment mean that many of us experience different cultures from an early age. But while we might be comfortable with cultural diversity, the unsettling rapidity of worldwide change requires us all to be more responsive to new concepts, new situations and new challenges. Adept at acquiring the new communication skills offered by social networks, we must be agile in responding to the changed world they produce. The boundaries are down, and that is true for our intellectual borders, too.

A business luminary pushing for environmental protection 商界翹楚馳騁環保世界 If acquiring a range of knowledge broadens one’s outlook, Dr William Yu Yuan-ping certainly has a fine view of the world. He has used his inter-disciplinary education to transform himself from a financial sector insider into a businessman and manager dedicated to environmental protection.

By Christina Wu

文：胡幗欣

Dr Yu started out with a bachelor’s degree in international business from CityU and went on to take an MBA at the Thunderbird School of Global Management in the US. At the same time, he was working for a US-based transnational corporation, a firm he stayed with for about ten years, devoting himself to exploring markets in Asia. He then went into academia, got a PhD and at the end of 2008 assumed the role of Head of Climate Programmes at the World Wide Fund for Nature, Hong Kong. The jobs might seem unrelated but there are several internal connections. “The experience I gained promoting commodities is a big plus when we advocate environmental protection and a green lifestyle,” Dr Yu said. When he swapped his career in the private sector for a teaching position at CityU, his alma mater, he found that he had important skills to impart. “As a university teacher, I helped my students understand abstract ideas and then communicate their thoughts and ideas in plain language, a skill I have to deploy every time I face an audience or the media,” he said. Keen to develop his academic career further, he left CityU and enrolled on a doctoral programme at the Judge Business School, University of Cambridge, in 2004. Inspired by the energy economists from the school, he decided to research energy and environment issues from an economic perspective and devote himself to environment protection. It wasn’t long before he had transformed himself into an expert on climate change, using his business acumen to promote related concerns. But such an inter-disciplinary journey was not without its problems. “In the past, I turned to my wide circle of friends and people I knew in the business

The Challenge of Labour in China

Social Studies, Stephen Cheung Yan-leung, Braham Prakash

New York/London: Routledge, 2010

Social Capital in Hong Kong—Connectivities and Social Enterprise.

China’s economic success has been founded partly on relatively cheap labour, especially in the export industries. In recent years, however, there has been growing concern about wages and labour standards in China. This book examines how wages are bargained, fought over and determined in China by exploring how the pattern of labour conflict has changed over time since the 1970s. It focuses in particular on the city of Shenzhen where labour conflict and workers’ protests have been especially prevalent. This book includes a detailed account of the transformation of labour relations and labour policy in China more broadly during 2004 to 2009, a period when there have been significant changes in the labour market, labour regulation and labour relations.

HK: City University Press, 2011 Given the rapid pace at which the Hong Kong Special Administrative Region (HKSAR) and other Asian economies are growing and the global volatility that these societies are experiencing, social capital and its diverse connectivities can furnish useful anchoring to communities, neighbourhoods, local governments and social protection networks. This volume in twelve chapters provides a critical analysis of social capital, its indigenous evolution and spread in the HKSAR. Some of the experiments and activities narrated in these chapters indicate the ingenious blending of the local ethos and culture with modern organisational forms and information networks. Policy makers, development practitioners, researchers of civil society organisations and welfare agencies will find this book a helpful reference source. 應用社會科學系伍錫洪講座教授、張仁良、Braham Prakash編《社會資本在香港 —— 互聯性與社會企業》，香港：香港城市大學出版社，2011年
