网络中的人、自由及文化

人在网络的存在是基于现实的存在，网络生活只是现实生活的一部分，不可能成为取代现实生活的力量。人在网络空间中的自由不是虚幻的，同样必须要从现实社会出发来理解才有意义，从个体角度理解网络中人的自由只会为整个社会带来更大的混乱。网络文化是网络技术同现实文化相结合的产物，最终它也不可能脱离现实的存在，它的形成对传统文化的挑战是一种必然。

Professional Cultures and Collaborative Efforts: A Case Study of Technologists and Educators Working for Change

The need for those working in a variety of settings to interact effectively with technical experts has grown dramatically in recent years as computers have become essential to the performance of an increasing broad range of professional work. This article presents a case of this sort of interprofessional interaction, exploring the process and outcomes of collaboration between technical professionals and educators working to bring Internet access to an urban public school district. Drawing on field note and interview data, the case reported here illustrates how differences in institutional routines and professional values can generate differing agendas, contrasting assumptions, and contrasting expectations concerning project products and outcomes among collaborators from different professional worlds. In the case we describe, these differences affected such central matters as the types and usefulness of technical resources to which users had access as well as users' confidence in the technology. The case also illustrates how aspects of this interprofessional conflict were addressed through an organizational change. The kinds of issues that arose in this project are likely to occur in a variety of professional settings; therefore, examination of this case provides insight into a variety of issues and dynamics that should be considered when embarking upon or analyzing any interprofessional collaborative effort, and particularly one that involves technical professionals.

New Media/Internet Research Topics of the Association of Internet Researchers

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others.

An information push-delivery system design for personal information service on the Internet

As Web-related techniques and equipment grow, the Internet has become popular as a major channel for providing a wide variety of information. However, users face the serious problem of information overload when acquiring increasing amounts of information from the Internet. This problem is one of the most important issues in providing information services to meet users’ requirements in an electronic commerce environment. In this paper, we propose an information push-delivery system, which applies fuzzy information retrieval and fuzzy similarity measurement to avoid the information overload problem. This proposed system is helpful for users to acquire suitable information from the Internet. An empirical investigation of the proposed system is implemented in this study. The results show that the degree of satisfaction for the received information for all participants was as high as 71%, indicating that the proposed system can effectively provide correct and interesting information for users.     

Neutralization theory and online software piracy: An empirical analysis

Accompanying the explosive growth of information technology is the increasing frequency of antisocial and criminal behavior on the Internet. Online software piracy is one such behavior, and this study approaches the phenomenon through the theoretical framework of neutralization theory. The suitability and applicability of nine techniques of neutralization in determining the act is tested via logistic regression analyses on cross-sectional data collected from a sample of university students in the United States. Generally speaking, neutralization was found to be weakly related to experience with online software piracy; other elements which appear more salient are suggested and discussed in conclusion.
