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

The New Midwifery, a form of community midwifery rooted in home birth and intensive prenatal and postnatal care, has attracted great controversy since its appearance in British Columbia in the early 1970s. On the one hand, this form of community midwifery has endured despite legal prohibition. Midwives derive an income from their practices, obtain necessary supplies and equipment, and are active in lobbying for recognition through the State. On the other hand, community midwifery is marginalized and illegal. Out-of-hospital births comprise less than one percent of births in British Columbia (and nationwide). Community midwives are excluded from the provincal Medical Services Plan and they lack hospital privileges if their clients are transferred to hospital. Community midwives are more likely than medical personnel to be tried for criminal negligence causing death and subject to prosecution under theMedical Practitioners Act of practicing medicine without a license.Community midwifery illustrates the structural limits placed on female birth attendants working outside the norm of professionally accredited, hospital situated childbirth. It is concluded that State measures in Canada structure power relations in a dialectical fashion. This includes measures to consolidate the monopoly status of the medical profession and the nursing profession, while temporizing about demands for independent midwifery practice. State powers are however relatively autonomous of dominant economic groups such as the Medical profession. Not all prosecutions of community midwives are successful, and contradictions in State policies surrounding monopolistic powers and civil liberties, and gender relations are evident.An earlier version of this paper was presented at the Canadian Sociology and Anthropology Association Meetings, University of Manitoba, June 1986. The author is grateful for resources provided through the Social Sciences and Humanities Research Council of Canada, the Department of Anthropology and Sociology (University of British Columbia), and the School of Criminology, Simon Fraser University. Comments from Carol Bullock, Nanette Davis, Bob Ratner, Livy Visano and the Journal referees have been helpful in revising this paper.  相似文献
