Federalism, as a concept and as a reality, received assistancefrom a variety of sources during 19941995. Opinion pollsrevealed a public strongly supportive of shifts in the balanceof power between federal and state governments. The new Republican-controlledCongress, bent on devolving authority to the states, busieditself with an ambitious legislative agenda. The DemocraticPresident pursued his principles of federalism and intergovernmentalrelations by supporting the unfunded mandates bill and by increasingthe use of the administrative waiver. The U.S. Supreme Courtbolstered federalism with its rulings in cases such as Lopez,a state challenge to the federal Gun-Free School Zones Act.The new mood in Washington, D.C. was complemented by state leadersanxious to take on the challenges of a rebalanced federal system 相似文献

The index of socioeconomic and cultural diversity among theAmerican states formulated by John L. Sullivan for 1960 is recreatedfor 1980. Comparisons are made between the index for the twotime periods, and changes among the states are examined overtime. Significant differences continue to exist between northernand southern states, mainly because of cultural rather thansocioeconomic factors. The diversity index remains a relativelypowerful predictor of policy variation among the states and,as such, might be considered as a substitute for geographicregion in comparative state policy research. 相似文献

Differentiating specialists and generalists within college students' social support networks 总被引:1,自引:0,他引:1

In order to examine the relationships among social network structure, types of social support, and determinants of support satisfaction, an alternative method was used to score the Social Support Questionnaire (SSQ). Factor analysis procedures suggested that college students' (N=198) social networks consisted of four groups: nuclear family, other family, friends, and others. Satisfaction with support was positively related to the proportion of the network occupied by nuclear family and negatively related to the proportion of friends in the network. Evidence was found for the presence of both support specialists and support generalists in the networks of the college students. These results are discussed from a developmental perspective with attention to the implications for interventions. 相似文献
