Explored the influence of life stress as mediated or moderated by locus of control, family environment, social support, and coping style on psychological adjustment and school performance in 164 ninth graders from Baltimore. Gender differences in findings were shown. For boys, family cohesion was the only variable found to protect against the effects of stress. Family cohesion did not serve protective functions for girls, and along with overall social support, was associated with increased vulnerability to school problems. The report of problem-focused coping strategies exerted a number of protective functions for girls only. External locus of control was found to increase boys' and girls' vulnerability to the effects of life stress. Empirical development of interventions to improve the psychosocial adjustment of inner-city adolescents is discussed.Received Ph.D. from Virginia Polytechnic Institute and State University in 1991. Research interests include evaluation of school mental health services, empirical development of interventions for children, and the impact of violence on urban youth.Received B.A. from Cornell University. Interests include stress and coping in children, identification of resilience factors, and evaluation of child mental health systems of care.Received Ph.D. from the University of Oklahoma in 1967. Research interests include psychophysiology, sleep disorders, and biofeedback and instrumentation.Received B.A. from Loyola College. Interested in applied work with adolescents and adults.Received M.D. from Duke University in 1968. Research interests include training in child and adolescent psychiatry, adolescent psychopathology, and the development of school mental health programs.  相似文献

Evidence is found that state-level economic conditions played a significant role in the defeat of George Bush in the 1992 U.S. presidential election. Evidence is also found which indicates that the entrance of Ross Perot into the race as an independent candidate was not instrumental in the Bush loss.  相似文献

This research modeled the extent to which the normative goals of equity and efficiency are embodied in three seminal tax reform proposals (Bradley-Gephardt, Kemp-Kasten, and the Treasury Department proposals) relative to the extant regime. The Tax Reform Act of 1986 (TRA86) is also modeled in the same manner. The objective of this study is to compare the equity and efficiency of the initial proposals with that of the final tax reform law. This before and after analysis is designed to ascertain the degree to which the legislative process undermined the normative goals of the tax reform movement. The National Tax Model was applied to model each regime and to measure the distributional and redistributional effects on tax burdens and wage efficiency costs associated with each system across ten income classes. The reform models, including TRA86, are shown as superior to the pre-reform system with respect to the normative criteria. The legislative process did not substantially compromise the goals as reflected in the seminal reform proposals in the development of a more politically acceptable tax reform law. This exercise demonstrates that it is possible for sound legislation to survive a political process that frequently permits the sacrificing of normative goals in favor of special interests.Financial support provided by the Arthur Young Foundation Tax Research Grant Program and The Ralph E. Kent Fund. The helpful suggestions of Jim Curtis were sincerely appreciated.  相似文献

The recent Supreme Court decision in Webster v. Reproductive Health Services giving more discretion to states to regulate abortion has led to speculation concerning which states might move to limit abortions. Medoff (1989) attempts to predict how state legislatures might vote on state-level abortion legislation by examining the 1983 Senate vote on the Hatch/Eagleton Amendment. We expand upon Medoff's analysis by incor- porating recent developments in agency theory as it applies to the political agents (i.e., Senators) in the empirical model. The results demonstrate that accounting for Senatorial "shirking" and state ideology substantially im- proves the predictive ability of the model for the Senate abortion vote. The predicted votes of the state's Senators, after eliminating the effects of apparent Senatorial shirking, are used to infer the likelihood of state-level legislation substantially restricting abortion. We compare these results to a base model that ignores the issue of shirking and find increased predict- ability and several differing results.  相似文献
