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

The Federal Republic of Germany celebrated its fortieth anniversaryin May 1989. In spite of the devastation brought by World WarII, the division of the country between East and West, and theloss of one-fourth of its territory, the Bonn Republic was foundedunder more propitious circumstances than was its democraticpredecessa after World War I, the Weimar Republic. Togetherwith an "economic miracle" that brought about economic growthand a high standard of living. West Germany experienced a "politicalmirracle" that led to governmental stability and a system asdemocratic as any other in Europe. Federalism has contributedto this miracle, and, in contrast to the nineteenth century,is now identified closely with democracy in Germany. The articlescontained in this volume provide a broad overview of postwarfederalism in Germany, from its origins, organization, strengths,and weaknesses, to interpretations and assessments of currenttrends and developments.  相似文献

It is by now widely accepted that social science research has only an indirect and general impact on public policymaking. Academic social science research, it is often argued, is antithetical to policy research: the former is animated by traditional scientific canons while the latter is specific and problem-oriented. Moreover, modern bureaucracies are now understood as political environments within which pure research will be routinely ignored if it does not serve someone's interests. For these and other reasons, social scientists are being encouraged either to eschew policy research or not to expect much influence. This article provides an alternative model of social scientists in the policy process, as consulting critics reviewing, analyzing and commenting upon substantive policy research. This model holds benefits for both scholars and clients, turns the canons of scientific inquiry into assets instead of liabilities, and responds to some of the concerns recently raised in the literature concerning the role of social science in the policy process.  相似文献

A precise method for evaluating election schemes   总被引:1,自引:0,他引:1  
A previously published paper evaluated election schemes under a wide variety of election circumstances. This paper improves upon the previous work by refining the measures used to rate the election schemes and increasing the statistical significance of those ratings. With these modifications, we can now draw some new conclusions:
  1. In general circumstances, the Borda System outperforms the Copeland System which outperforms Approval which outperforms Majority Rule.
  2. The Maximin Rule — strongly supported by Rawls's — turns out to be a reasonable election rule if the number of election alternatives is large relative to the number of voters.
  3. With two exceptions, all our election systems performed quite well given a society with highly correlated utilities.
  4. Given a polarized society, a serial dictatorship was better than every other election system except Borda.
Perhaps even more importantly, we now have the possibility of conducting some cost/benefit analyses of different proposals for electoral changes.  相似文献

There is always a temptation to suppose that one's own problems (whether personal or national) are unique. They rarely are. The "problem" of the elderly is no exception and so there is no particular point in looking to the specific characteristics of one's own health, social service, and social security systems for causes. There is, however, every reason to be looking at them for the consequences. They can also exacerbate the causes. In this paper we sketch the principal features (economic, social, and demographic) that have contributed to the "problem" of the elderly in Europe and then outline the main intellectual issues that need to be explored and resolved. That sounds a bit pompous but, if one is to avoid an intellectual morass consisting of the various assertions about needs, obligations, and so on that emanate from rival concerned parties and various professional interests on the one hand, and simplistic political slogans whose only virtue is that they cut the Gordian Knot (but provide no real enlightenment) on the other, then we need to be doing just this. We shall take a few things for granted: that cost-containment is not the be-all-and-end-all of policy; that value for money depends equally on what you get as on what you spend; that overall expenditure per head is mainly determined by income per head (though some countries have managed to get and stay below the regression line); and that it "ain't so" that all one needs to do is to "leave it to the market." To have justified each of these would have taken too much space so we can only assert them and trust that, in swallowing these camels, you won't strain at the gnats to come.  相似文献
