D A Stone 《Journal of health politics, policy and law》1979,4(3):507-521
This article argues that the concept of illness has certain properties that make it a convenient administrative device for managing a need-based redistributive system in a society whose primary distributive system is based on work. These properties--cultural acceptance of illness as a legitimate excuse for not working, objective standards for identifying illness, and restrictiveness--have led to the widespread use of illness as an eligibility criterion for many social benefits, including cash transfers, services, privileges and exemptions. Paradoxically, the traditional rationales for using illness as one of the keystones of categorical welfare policy are eroding, yet welfare programs based on illness certification are growing rapidly. To explain this anomaly, the author suggests that medical certification as a distributive mechanisms serves certain latent political functions, such as allowing welfare programs to be responsive to political unrest, siphoning off opposition to controversial policies by the granting of medical exemptions to intense opponents, are reducing political conflict by using physicians as arbiters. 相似文献

Debates concerning the taxation of prostitution have occurred in taxation law and in feminist literature. This article will integrate the case of Polok v. C.E.C. [2002] E.W.H.C, 156; [2002] S.T.C. 361, within the feminist legal canon. The case is discussed in the context of the argument of the European doctrine of fiscal neutrality, which dictates that, regardless of legality as amongst member states, if an activity is levied to V.A.T. in one member state, V.A.T. should be levied on it in all member states. The doctrine of sovereignty accepts the possibility that the integrity of the V.A.T. system may be compromised by the levying of tax on illegal activities, in terms of the cooperation between tax and other aspects of the U.K.’s legal system. European law, feminist law, commodification and the marketplace are all considered within the context of these principles. The article also considers the place of Polok within standard feminist texts on prostitution. Different paradigms of prostitution define different aspects of prostitution as ‘problems’, and the article considers the implications within a feminist reconstruction of Polok of this. The article suggests that the challenge for a feminist analysis of Polok is to remain within the realm of European tax and competition law, and to render the perspective of the employees of the Polok taxpayers part of the substance of the deliberations of the case. 相似文献

In this article, we test: (a) the relation between school-based extracurricular participation and indicators of positive and
negative development across a range of activity contexts, and (b) a mediation model linking activity participation, prosocial
peers, and development. Extensive survey information was collected from a predominately White sample of middle class adolescents
in 9th, 10th, and 12th grades. Extracurricular participation was related to more favorable academic, psychological, and behavioral
adjustment; the pattern of findings differed by activity and outcome. In addition, we documented some support for the hypothesis
that the link between extracurricular participation and positive adjustment is partly a function of associating with a prosocial
peer group. Implications of these findings and suggestions for future research are presented.

The first aim of this study was to examine the structure of externalizing and internalizing problem behavior during early
adolescence. Our second aim was to determine the stability of these problems for boys and for girls over time. A total of
650, 13–14-year-olds filled out (an expanded version of) the Youth Self-Report [YSR; Manual for the Youth Self-Report and 1991 Profile. Department of Psychiatry, University of Vermont, Burlington] 2 times with a 1-year interval. By using confirmatory factor
analyses (CFA) to test a series of competing models, a hierarchical model provided the best representation of the structure
of problem behavior at both Time 1 and Time 2: externalizing and internalizing problem behavior represent distinct aspects
but the model also demonstrates the existence of comorbidity at a higher level. This model appeared to be stable over time
for both boys and girls. The relative stability of problem behavior was found to be high for boys and girls. Absolute stability
for both externalizing and internalizing problems appeared to be higher for boys scoring in the lower range of problem behavior.
