Presented in this essay are suggestions for rewriting Roe vs. Wade, the case that resulted in the establishment of a constitutional right to abortion. Essentially, the argument is 1 of equal protection. It is suggested that abortion be viewed as presenting a problem that might be termed "the law of samaritanism" -- the law regarding obligations imposed on certain individuals to provide assistance to others. In American law it is a deeply rooted principle that an individual is ordinarily not required to volunteer assistance to another individual who is in danger or in need of aid. The argument presented maintains that if a pregnant woman is required to carry the fetus to term and deliver it, then she is being compelled to be a Good Samaritan. It is argued further that if the generally limited scope of obligations of samaritanism under current law are considered, and the special nature of the burdens imposed on pregnant women by laws forbidding abortion are also considered, the obvious conclusion is that the equal protection clause forbids imposition of these burdens on pregnant women. The argument is developed in a lengthy form and calls for an extended discussion of the law of samaritanism. The uniqueness of the abortion case also creates problems as the equal protection argument is approached, and an approach to equal protection questions is sketched.  相似文献

The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R + n , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship.  相似文献

In this paper two arguments are advanced with regard to parental influence on adolescent political attitudes. First, variables like parental affect, which are of considerable theoretical interest to social psychologists, are of relatively little interest to the system-level concerns of political scientists because of their lack of variance. Second, the additive issue salience/perceptual accuracy model I proposed (1974) is a better fit to the data than a multiplicative cue-giving/parental affect model proposed in this journal by Cundy (1979). The fit of the two models is tested with the Jennings (1965) socialization data.Cundy, D. T. The dynamics of interpersonal attitudinal influence.Political Behavior, 1979,1, 269–284.  相似文献

Abstract. In an attempt to tighten up its financial systems and improve control of expenditures, the Canadian federal government has set up a new office, that of the Comptroller General. One of this Office's responsibilities is to administer the Treasury Board's policy on program evaluation, which says that all government programs should be periodically reviewed for their effectiveness in meeting goals and for the efficiency with which they are managed. The paper describes the Office's approach to program evaluation, reviews program evaluation policy in three other countries and discusses the principles and practical problems which limit the application of evaluation research. Evaluation activity in Canada is endangered in its cradle by two threats: the tendency of proponents to over-exuberance; and the cynics' view that the activity is of such limited applicability that potential savings are negligible. A third problem is a tendency to fuse together policy-related and management-related assessment activity. Evaluation activity conducted from the operational management point of view which takes program goals for granted will surely result in sequences of small victories and economies. This is worth doing well. But the dramatic import of effectiveness evaluation as a ‘bottom line’ for judging the worth of whole programs — that is, as a policy tool — should not be allowed to generate false expectations about the scope for improvement in routine management of the public service. Sommaire. En vue de fortifier ses systèmes financiers et d'améliorer le contrôle exercé sur ses dépenses, le gouvemement fédéral canadien a créé un nouveau poste, celui du Contrôleur général. Une des responsabilités de cette function est d'administrer la politique du Conseil du trésor en matière d'évaluation de programmes. Cette politique exige que les programmes gouvernementaux soient évalués périodiquement afin de déterminer leur efficacitéà rencontrer leurs objectifs ainsi que la capacité de rendement de leur gestion. Ce document décrit l'approche du Bureau du Contrôleur général en matière d'évaluation de programmes; examine les politiques correspondantes dans trois autres pays; et discute des principes et des problèmes pratiques qui limitent l'applicabilité de l'évaluation en recherche.  相似文献
