Robert Higgs 《Public Choice》1989,63(2):175-181
U.S. senators frequently vote against the preference of their constituency, assuming that such a preference exists. Both of a state's senators represent the same constituency. Whenever they split their votes, one or the other is necessarily going against the constituency preference. For the sample of defense-related votes analyzed above, misrepresentation — either observable vote splitting or unobservable vote matches that go against the constituency preference — occurred at least 37 percent of the time, at least 46 percent on one vote. Although party differences accounted for more than two-thirds of the vote splitting, a substantial number of splits remained. Besides, a party difference for a state's senatorial pair is itself problematical.The method employed here can be applied easily to any data whatever on senatorial voting. Its application will show that, quite often, many senators depart from constituency preference. This finding refutes the hypothesis, popular in certain circles, that ours is a more or less perfect political market with little or no scope for ideologically driven voting by legislators.  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

In Morgentaler v. R., the Supreme Court of Canada struck down the abortion provisions in the Criminal Code. In a five to two split, a majority of the Supreme Court judges found that section 251 offended a pregnant woman's constitutionally protected right not to be deprived of her "life, liberty, and security of the person." Sheilah Martin reviews the three majority judgments and focuses on the decision written by Madame Justice Wilson. She believes that Madame Justice Wilson's opinion merits special attention in several regards: her conclusions on the constitutional rights of pregnant women; her recognition and validation of women's perspectives on abortion; and her approach to balancing women's interests in reproductive self-determination against the state's interest in regulating reproduction. Sheilah Martin concludes that this decision will reverberate far into the future. Even though it fails to establish clear guidelines concerning governmental power to control access to abortion, its principles outline the legal framework in which future litigation will occur, and it will limit and shape the terms of any ensuing political debate. In addition, Madame Justice Wilson's judgment holds great promise for those looking to the Court to promote the rights of women and other historically disadvantaged groups.  相似文献

The presence of smeared or unsmeared ink on the skin resulting from the writing process has been observed in a number of suicide victims who have left suicide notes. The authors report a case of a palmar "cutaneous ink sign" and discuss its forensic science import.  相似文献

This article is adapted from a paper presented at a conference that investigated the role of policy research in shaping public policy. The conference focused on how studies of economic and social forces and their relationship with public problems and programs affect the decisions of public policymakers. The author contends that research has the potential to inform policy-making in any of its five stages: problem identification, option development, passage of new laws or development of new procedures, implementation, and evaluation. She notes that different players in the policy-making process use research differently, from the senior government official who needs a quick review of what is known relating to a "hot" issue to the interest group lobbyist who wants access to raw data. The article concludes that research can best achieve its potential when (1) it anticipates policymakers' information needs, (2) it is disseminated in an accessible form understandable to nonresearchers, and (3) the policy analyst is willing to engage in the policy process as an advocate for efficiency.  相似文献

One of the important resources to any state, such as California, is the technology that is available from the many federally operated and/or funded laboratories within its borders. In this age of technology a state needs to take advantage of applications of modern technology and innovative exploitation of human and natural resources. This article illuminates the importance of the Federal Government research laboratories. Many examples are presented to support the argument that the Federal Government research laboratories can be and often are substantial contributors to the storehouse of technology that finds its way to the private sector and public sector. Several types of technology transfer are discussed, i.e. primary technology, secondary applications, mission related, technical assistance and cooperative. In addition the article discusses the structure and logic of the Federal Laboratory Consortium for Technology Transfer (FLC). The legislaltion that has helped to make the FLC effective is discussed. Included in the discussion are insights of how the FLC operates and how the private sector and public sector may use the FLC in order to locate process, product and service technology.  相似文献
