Peltzman [Peltzman, S., 1984. Constituent interest and congressional voting. Journal of Law and Economics 27, 181–210] argues that if constituents’ economic interests have well-defined “winners and losers” and are appropriately measured, then constituents’ economic interests, and not legislator ideology, are the most important determinates of legislator voting. We test Peltzman's theory by examining senatorial voting on three mandated spending limitation bills. We find, consistent with Peltzman's theory, that the ratio of federal spending in a senator's state to federal taxes paid by that state, and not a senator's personal ideology, matters on legislation where there are well-defined economic “winners and losers.” This is particularly important because unlike other constituents’ economic interest measures that only impact a fraction of the constituency, the ratio of federal spending to federal taxes in a state represents the economic interests of all the constituents in a state. 相似文献

Gay affirmative practice has recently been introduced into the social work literature as a culturally sensitive model for
working with gay, lesbian, and bisexual (GLB) adults, however, this model has rarely been applied to practice with GLB youth.
In this article, the authors review the literature to present the main tenets of gay affirmative practice, outline the challenges
that GLB youth face, and delineate the environmental and individual strengths that can be enhanced to promote well-being.
The authors then apply the gay affirmative practice model to GLB youth, offering concrete information about the specific knowledge,
attitudes, and skills that social workers should acquire to better serve the unique, yet diverse, needs of GLB youth. 相似文献

Cultural and professional associations are the expression of the modern society with structured organisations. The 19th century was the marking epoch of the constitution of associations in Germany. The involvement of associations in the political live, specially the professional ones, is typical in Germany. While political sciences focus on the analyses of interest representation and mediation functions of organisations, sociology research covers the full range of social, psychological, political and economical functions of organisations. Management and especially human resource management topics are presently gaining a growing importance within the research community which focuses on the cultural and professional organisations. 相似文献

Immigration is contributing to the U.S. population becoming increasingly ethnically diverse. This article examines the role of family relations and well-being among different generations of Black Caribbean immigrants. Family disruptions, such as migration, can have complex effects on the support networks and emotional well-being of family members. Data from a recently completed national study of American Blacks in the United States, however, reveal significant similarities across ancestry and immigrant status in family contact, solidarity and well-being. It is concluded that intrafamilial relations may serve to overcome barriers of geographical distance in providing comparable levels of contact, solidarity, and well-being for both U.S.-born and immigrant Black Caribbean family members of different generations. Because of the increasing numbers of immigrant elders, these sources of family support will become increasingly more important in bridging the gaps between government resources and needed assistance in an aging society. 相似文献

Sets of alternatives as Condorcet winners 总被引:1,自引:0,他引:1
We characterize sets of alternatives which are Condorcet winners according to preferences over sets of alternatives, in terms
of properties defined on preferences over alternatives. We state our results under certain preference extension axioms which,
at any preference profile over alternatives, give the list of admissible preference profiles over sets of alternatives. It
turns out to be that requiring from a set to be a Condorcet winner at every admissible preference profile is too demanding,
even when the set of admissible preference profiles is fairly narrow. However, weakening this requirement to being a Condorcet
winner at some admissible preference profile opens the door to more permissive results and we characterize these sets by using
various versions of an undomination condition. Although our main results are given for a world where any two sets – whether
they are of the same cardinality or not – can be compared, the case for sets of equal cardinality is also considered.

La documentation sur le sujet n'est pas décisive quant à savoir si léconomie ethnique enclavée enregistre un rendement économique comparable chez les travailleurs et les entrepreneurs immigrants à ceux qui se situent dans le courant économique principal. Les auteurs de cette étude utilisent des données du Recensement du Canada de 2001 sur la langue la plus utilisée au travail din de mesurer la participation des immigrants chinois à léconomie enclavée. Après les avoir comparés au capital humain ainsi qu'aux variations liées au travail et au milieu urbain, les résultats démontrent que le rendement est moins élevé chez les hommes et chez les femmes de l'enclave que celui des gens qui se trouvent dans le courant économique principal. Les caractéristiques de la langue et le type de travail qui s'effectue dans léconomie enclavée expliquent pourquoi le rendement y est inférieur à celui obtenu dans le courant économique principal. The literature in inconclusive as to whether the immigrant enclave economy offers returns to immigrant workers and entrepreneurs comparative to those in the mainstream economy. This study uses data from the 2001 Census of Canada on language most often used at work to measure enclave economy participation for Chinese immigrants. The findings show that returns are lower for men or women in the enclave than those in the mainstream economy, respectively, after controlling for human capital, work‐related and urban variations. Language features of and job type in the enclave economy explain why returns are inferior to that of the mainstream economy. 相似文献
