Daniel R. Vertrees 《The Journal of Technology Transfer》1989,14(3-4):37-42
The computer-mediated network is a moderately expanding phenomenon. A major reason for this growth is the need for transferring technology to developing nations. But because many of these nations are not traditional users of advanced technology and because even the purveyors are not yet fully comfortable with the networks, the medium is not being used as much as perhaps it ought to be. In establishing a multinational network, one should be careful to treat all potential users with equity and not create an informational elite. Part of the challenge of such a system is making it accessible to operatives in the field. An effective way of introducing a network is to blend it with existing technologies, keep the costs down and the quality of information up, provide a usable information-retrieval system, and pay attention to microand macro-ergonomics. The Adult Education Network (AEDNET) of the Kellogg Project at Syracuse University has started working on a next-generation computer-mediated network system. It is proposed that AEDNET involve three action groups in the project: researchers, those interested in social implications, and users. 相似文献

Conventional left accounts of Thatcherism have stressed the authoritarian nature of its political rhetoric. This paper suggests that convergences between the new conservatism and more fundamentalist moral positions, meeting on the ground of obscenity and violence in the media, are a relatively recent development, associated with renewed strategic concentration on the question of law and order. Indeed, the libertarian right, in adhering to a utilitarian laissez-faire understanding of private pleasures, has presided over a positive proliferation of erotic and other gratifications. We argue that in the United Kingdom the authentic constituency of the moral right is an increasingly socially marginal one, rendered progressively more so by the rapid development of technologies of communication and entertainment. 相似文献

Fox DM 《Journal of health politics, policy and law》1986,11(2):195-197
A conference was held at the State University of New York at Stony Brook in October 1984 to discuss the controversy concerning treatment of a newborn with severe congenital defects that became known as the Baby Jane Doe case. Fox provides some background information on the case to introduce a set of of six articles consisting of papers delivered at the conference. These articles deal with historical aspects of the treatment debate (Stanley J. Reiser), problems of clinical decision making (John M. Freeman), the legal issues involved (John A. Robertson), coverage of the case by the media (Stephen Klaidman and Tom L. Beauchamp), federal efforts to regulate the treatment of handicapped newborns (Lawrence D. Brown), and the alliance that arose between opponents of abortion and advocates of the rights of the handicapped (Constance Paige and Elisa B. Karnofsky). 相似文献
