International Joint Conference on Neural Networks, IJCNN 2005
作者: Holmstrom, Lars Santiago, Roberto Lendaris, George G. NW Computational Intelligence Laboratory Portland State University Portland OR 97201 Systems Science Ph.D. Program Department of Systems Science and Electrical and Computer Engineering
Mathematical models are often used in system identification applications. The dynamics of most systems, however, change over time and the sources of these changes cannot always be directly determined or measured. To m... 详细信息

Proceedings of the 2004 Congress on Evolutionary Computation, CEC2004
作者: Fletcher, Jeffrey A. Zwick, Martin Systems Science Ph.D. Program Portland State University Portland OR 97207
Reciprocal altruism and inclusive fitness are generally considered alternative mechanisms by which cooperative, altruistic traits may evolve. Here we demonstrate that very general versions of Hamilton's inclusive ... 详细信息

Journal of Computer-Mediated Communication 2006年 第3期8卷
作者: Barry Wellman Anabel Quan-Haase Jeffrey Boase Wenhong Chen Keith Hampton Isabel díaz Kakuko Miyata In 1965 moved from his Bronx High School of Science slide rule to IBM cards and an 029 keypunch in the bowels of Harvard University. Since then he's been primarily interested in the interplay between large-scale social processes and how people use technology to be connected at work and in the community. His NetLab research network is trying to get a handle on how the Internet fits into everyday life. Wellman founded the International Network for Social Network Analysis in 1976. He is a recent Chair of the Community section of the American Sociological Association has been nominated for the Chair of the Communication and Information Technology section of the ASA the Virtual Community focus area leader for SIGGROUP/ACM and a Executive Cmmittee member of the Association for Internet Researchers. Wellman's (co)edited books are: Social Structures: A Network Approach (2d ed CSPI 2003) Networks in the Global Village (Westview Press 1999) and The Internet in Everyday Life (Blackwell Publishers 2002).

Doctoral student at the Faculty of Information Studies University of Toronto. She has been a Fellow of the Knowledge Media Design Institute and the McLuhan Program in Culture and Technology. Her articles address the nature of Internet-related social change for social integration and information flow. Her articles have examined the implications of these changes for communities and her thesis focuses on organizations. University of Toronto doctoral
We review the evidence from a number of surveys in which our NetLab has been involved about the extent to which the Internet is transforming or enhancing community. The studies show that the Internet is used for conne...
