Engendering Democratic Participation via the Net: Access, Voice, and Dialogue     

Nancy B. Kurland 《The Information Society》1996,12(4):387-406

Information technology in the form of the Internet and its commercial offspring (referred to in this article collectively as the Net) has received much attention as a vehicle to increase political participation. In this article, we explore the potential of the Net, a vast, loosely coupled system of electronic forums, for facilitating and hindering democratic participation. In so doing, we identify five assumptions that undergird the claim that the Net will enhance democratic participation and suggest that increased democratic participation rests on three fundamental characteristics: access, voice, and dialogue. In order for this network of electronic forums to facilitate democratic participation, educational, economic, and cultural barriers to access, voice, and dialogue must be overcome. The final part of this article raises additional challenges to realizing democracy via the Net.  相似文献

Researching Internet Communities: Proposed Ethical Guidelines for the Reporting of Results   总被引：4，自引：0，他引：4  

Storm A. King 《The Information Society》1996,12(2):119-128

Communication researchers and social scientists are quickly discovering the value of data that exists in the postings of members of Internet e-mail, Usenet, and real-time groups. The ability to communicate with one's peers, no matter how esoteric the interests, is causing an explosion in the number of new virtual communities. The interpersonal dynamics of these groups are increasingly coming under the scrutiny of academic research. The publicly available archived records of Internet virtual communities are being analyzed for a wide variety of research interests. The ability to do naturalistic observations of group dynamics, as they are exhibited in these exchanges of text, has captured the attention of many researchers. The institutional review boards of major universities are granting researchers exempt or expedited (exempt from full review) status for this work, due to the public nature of the notes being analyzed. These studies often involve the lack of informed consent, where the group members under study are unaware they are being monitored. There is a potential for psychological harm to the members of these groups, depending on the way results are reported. This article explores the ethical considerations that must be taken into account to protect cyberspace participants. The guidelines proposed are based on the American Psychological Association ethical guidelines for use of human subjects in research. An explanation is offered as to how such guidelines can best be applied to the study of Internet communities. The constructs of Group Accessibility (the public/private nature of the actual cyberspace occupied by a group) and Perceived Privacy (the level of privacy that group members assume they have) are defined and proposed as two dimensions by which individual Internet communities may be evaluated in order to assure the ethical reporting of research findings.  相似文献

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

Ann Locke Davidson  Janet Schofield  Janet Stocks 《The Information Society》2001,17(1):21-32

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.  相似文献
