Report from National Sun Yat-Sen University by Dan Power From December 17, 2005 to January 8, 2006, I visited Taiwan and more specifically the southern port city of Kaohsiung. I was invited to spend 3 weeks as a Visiting Scholar at National Sun Yat-Sen University (NSYSU) by Professor T.P. Liang. Our plan was to work on some joint research projects related to Decision Support Systems. My host, Ting-Peng Liang (T.P.), is the National Chair Professor and Director of Electronic Commerce Research Center at NSYSU. Professor Liang is probably the most visible and influential DSS researcher in Asia. He is a prolific scholar and most recently co-authored with Efraim Turban and Jay Aronson the seventh edition of a textbook titled Decision Support and Intelligent Systems (2004). Facing west toward Hsitzu Bay and the Taiwan Strait, National Sun Yat-sen University has a beautiful campus with the Port of Kaohsiung lying to the south and east and Mount Chai rising to the north. NSYSU has approximately 10,000 students and graduate students comprise about half of the student body. For more about the University check www.oia.nsysu.edu.tw. The beautiful setting, 70 degree weather and sunshine was a welcome relief from the snow and cold in Iowa. As always, the long plane rides, security checks and waits in airports to change planes is the downside of International travel. My office was in the College of Management and I was a Visiting Scholar in the Department of Information Management and the Electronic Commerce Research Center. The Department of Information Management has approximately 20 faculty. Professor Nian-Shing Chen is the Chair of the department. What about the projects? Professor Liang invited me to participate in two ongoing projects. One involves an empirical study of the impact of Knowledge Management (KM) activities on firm performance and the other is a conceptual paper on time-constrained model selection. The KM project has been ongoing for about 2 1/2 years. During my visit I reviewed all aspects of the design, data collection and current analyses. One of the first big tasks Professor Liang and I tackled with the assistance of Yen-Ching OuYang, a Ph.D. student who has worked on the project from its inception, was translating the survey questionnaire into English. Yen-Ching prepared an initial translation, then I tried to improve the English word choice; Prof. Liang reviewed the translation and prepared a second translation. Then we used Babelfish (babelfish.altavista.com) and prepared a machine translation from Mandarin into English. After more wordsmithing, reverse translation and critical analysis we finalized the translation. This long process made it possible for me to examine the constructs in the questionnaire and interpret the statistical analysis and results. I probably worked 100 hours on the overall project while I was at NSYSU. We are nearing completion of a working paper titled "Effects of Knowledge Management Process Activities on Perceived Performance: An Empirical Examination". On the second project I was working with Prof. Liang and Ching-Chang Lee, an Associate Professor at National Kaohsiung First University of Science and Technology. Prof. Lee completed his dissertation under Prof. Liang's supervision. This project did not receive as much time and attention as needed for a number of reasons, but some progress was made. We are examining the broad issue of how to support DSS users who must select among multiple models to analyze a specific decision in a time-constrained situation. The Internet, Web services, and application service providers make it relatively easy to include multiple models with varying data requirements in a model-driven DSS. For example, the NEOS server for optimization (www-neos.mcs.anl.gov) has 14 categories of optimization software that can be accessed using the Internet including linear programming, integer programming, network optimization and quadratic programming. The conceptual approach in this project uses time as a primary metric to make the selection about the most appropriate model component in each specific decision instance. TIME is a complex metric involving collecting data for the parameters, constructing and explicating the actual model, computing the initial solution and results, performing sensitivity and "what if?" analyses, etc. For example, in a bidding situation in a time-constrained auction environment, multiple models could potentially be used to evaluate the maximum bid amount in the context of a dynamic bidding environment. A similar situation might occur in some military command and control situations. Once the bidding begins, an initial solution from one or more models may need to be revised with new data and alternative model formulations may become more or less appropriate. The DSS user then needs to select a "new" model or revise prior analyses under the time-constraint. What else was learned? One goal I had for my visit was increasing the amount of Mandarin language content materials at DSSResources.com. Ideally a knowledge repository should support users in their native languages. Specifically, I'd like to have at a minimum key Ask Dan FAQs translated. My son Alex, who is studying Mandarin and is the Webmaster at DSSResources.com joined me at NSYSU for 8 days to investigate this possibility and to provide me some company for social activities. He made a few contacts with students and helped with Babelfish, but this goal remains an ambitious one. I have not been doing much interactive data analysis in recent years, but it was great to watch Yen-Ching use SPSS on a portable PC to prepare data analyses. Data analysis is so much easier and faster than in the days when I used mainframes and even desktop PCs for SPSS. Interpreting the results is still difficult and perhaps it is even more important now to be slow and deliberate to check that no errors or problems occur with the data or analyses. Almost everyday while I was at NSYSU, I used email and chat on MSN Messenger to communicate with my wife and sons in Cedar Falls, Iowa. The time difference is 14 hours and so having a synchronous chat usually happened for me in the morning which was evening back in Cedar Falls. Chat is so much slower than using the telephone and my "hunt and peck" typing made it worse. It was an inexpensive substitute and it did create a record of our conversation. One problem with IM involving acronyms became clear when I returned to Cedar Falls. I was routinely signing off with LOL thinking that meant "Lots of Love". My wife thought LOL meant "Laugh out Loud". Well in three weeks one does so much, but I'll just mention a ferry ride to Chi-chin Island for a fresh sea food lunch, visits to the Jade Market and Night Market in Kaohsiung and an Aloha Bus ride to Taipei as highlights. The long distance buses in Taiwan hold about 20 passengers in great comfort with TV and a stewardess onboard. If only I could have taken the bus all the way back to Cedar Falls. At the Jade market, I was looking for items for my collections, especially Chinese coins and currency. The problem with counterfeit or reproduction Chinese coins is increasing so I didn't buy much. Let me close by specifically thanking Prof. T. P. Liang who was a gracious host and a good collaborator. He also secured the funding for my trip. Also, many thanks to Yen-Ching, Ching-Chang and all of the wonderful people I met. Zai jian. References Turban, E., J.A. Aronson, and T.P.
