Introduction     
Gunlicks  Arthur B. 《Publius》1989,19(4):1-15
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

This article reviews recent case and statutory law concerning patients who refuse medical treatment. Among the special cases considered are: the competent adult patient who refuses treatment on religious or privacy grounds; the incompetent patient whose own wishes were never expressed, but whose family refuses treatment; the incompetent patient who expressed the wish not to be treated before becoming incompetent; and parents who refuse treatment on behalf of their child. It is pointed out that recent court decisions have blurred the distinctions between "extraordinary" care and "ordinary" care and between withholding and withdrawing life-sustaining treatment. Reference is made to the recent trend toward allowing the family of an incompetent patient to assert the patient's rights without court intervention either in the form of direct court order or through guardianship proceedings. Finally, the implications of these legal developments for health care institutions are discussed. A protocol pertaining to incompetent patients is proposed. Health care institutions are encouraged to develop formal policies for dealing with patients who refuse treatment, and to work with their professional associations in lobbying for legislation which will clarify the law in this area.  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
