Conclusion It is necessary to strike the correct balance between safeguarding the rights of the individual and engendering mutually beneficial cooperation between states in extradition matters. In the absence of effective global international human rights enforcement mechanisms, many of the traditional safeguards still have a real role to play in extradition. This article reviewed five such safeguards and found that all but the nationality exception should be retained to ensure that international cooperation and individual protection are both safeguarded for the common good of society.This is a revised version of a paper presented at an international workshop on Principles and Procedures for a New Transnational Criminal Law, organized jointly by the Society for the Reform of Criminal Law and the Max Planck Institute for Foreign and International Criminal Law, Freiburg, Germany, May 21–25, 1991.LL.B., University of Exeter 1973; LL.M., Osgoode Hall Law School 1974; D.

This study concerns the relationship between knowledge of drug culture and substance use. Results from a sample of 2,635 middle and high school students indicate that (1) knowledge of drug culture is positively correlated with substance use; (2) drug knowledge is more reliable and coherent in older youth; (3) drug knowledge is unrelated to other kinds of knowledge acquired in school; (4) youth exposed to peers' substance use in school have more drug knowledge; and (5) the earlier young people begin using drugs and alcohol, the more they know about the drug culture. Results suggest that knowledge of the drug culture may be an unobtrusive indicator of substance use problems.This project was made possible by a grant from the Tulsa Psychiatric Center, Tulsa, Oklahoma.Received Ph.D. from University of California at Berkeley in personality psychology.

During preliminary examination of the body of a homicide victim, a peculiar red "fiber" was noticed and recovered. Initially believing this to be a carpet fiber, the item was subjected to fiber analysis. It was found to be a short coiled particle not like any known natural or synthetic fabric fiber. Subsequent examinations determined this "fiber" to be the larva of a common freshwater midge (Diptera; Chironomidae). Chironomid larvae have been observed on other bodies recovered from freshwater environments. Entomological studies of this organism have led to the conclusion that the presence of chironomid larvae indicates submersion of the body. 相似文献

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
Robert F. Bordley 《Public Choice》1985,46(2):113-123
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:
- In general circumstances, the Borda System outperforms the Copeland System which outperforms Approval which outperforms Majority Rule.
- 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.
- With two exceptions, all our election systems performed quite well given a society with highly correlated utilities.
- Given a polarized society, a serial dictatorship was better than every other election system except Borda.

A split-ballot experiment shows that, when people are asked how interested they are in following political campaigns, their response depends not only on the order in which the question is asked, but also on the broader electoral context in which it is posed. When asked how interested they were in following the political campaigns immediatelyafter a question about whether or not they voted in the (1982) election, people were more likely to think they were interested in the campaign, especially if they claimed to have voted, than if they were asked about it immediatelybefore the question on whether or not they voted. This order effect, however, appears to depend onwhen the questions are asked. If asked within a few weeks after the election, there is little or no order effect. But later, as the memory of the campaign fades, the order of the questions makes a sizable difference in the results. This order effect also seems to be more pronounced among better-educated respondents, suggesting that they are more likely to feel pressured by a social norm to vote and to express an interest in political affairs, not only in real life, but in the survey interview as well. The paper concludes with a brief discussion of the implications for the design of the interview schedule used in the American National Election Studies.The research reported in this paper was supported by a grant from the National Science Foundation (SES81-11404). 相似文献
