Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health.  相似文献

The present investigation explores the relations among midlife identity concerns, marital satisfaction, mental health, and parenting satisfaction among mothers of preadolescents and early adolescents. Data were obtained from 129 intact families with a firstborn child between the ages of 10 and 15. The results suggest that intense midlife concerns are associated with diminished satisfaction with parenting, although this relation is moderated by the mother's reported marital satisfaction and her overall psychological wellbeing. Specifically, mothers with intense midlife crisis symptoms report higher parenting satisfaction when their marital satisfaction is high, but lower parental satisfaction when their midlife concerns are accompanied by psychological distress. The relations among midlife concerns, marital satisfaction, psychological symptoms, and mothers' satisfaction with parenting are not moderated by the sex of the adolescent.The research reported here is part of a larger investigation supported by grants to the second author by the William T. Grant Foundation and the Graduate School Research Committee of the University of Wisconsin —Madison. This paper is based on a senior thesis completed by the first author in the Department of Child and Family Studies at the University of Wisconsin—Madison.Interests are in adolescent development and sex differences.Interests are in adolescent development and family relations.  相似文献

He has testified before Congress many times and has written and spoken extensively on legislative-executive relations, the federal budget process and science policy, particularly as it affects the social and behavioral sciences. This report was prepared by the author with the assistance of the COSSA staff.  相似文献

Among the best-known theorems of fiscal federalism is the presumed allocative and distributive equivalence between a lump-sum grant to a collectivity and a set of lump sum grants to the members of a collectivity. Interestingly, the simple elegance of the theorem is at odds with observed behavior. Grants to governments produce greater public spending than does tax reduction. Explanations of this "flypaper effect" range from misspecified econometric modeling to presumed behavior based on fiscal illusion. In this paper we show that theoretical equivalence exists in a model that recognizes only one tax share, the citizen voter's local tax share. When the model is expanded to include voters' federal tax shares as well as local taxes, non-equivalence and the flypaper effect become the rule, not the exception.  相似文献

Smoking bans are gaining widespread support in the United States and other countries. While supporters argue that bans are necessary to resolve market failures associated with negative externalities, the Coase Theorem predicts that, under various conditions, private markets internalize negative externalities. We examine the smoking issue within the framework of the Coase Theorem and hypothesize that smoking bans misallocate air space resources shared by smokers and nonsmokers. Because smoking bans shift ownership of scarce resources, they are also hypothesized to transfer income from one party (smokers) to another party (nonsmokers). Supporting evidence for these hypotheses is provided by an examination of a comprehensive smoking ban imposed in San Luis Obispo, CA.  相似文献

This paper analyzes an exchange rate policy game between a central bank and rational speculators under symmetric information. The central bank tries to counteract shocks to the exchange rate by means of sterilized intervention working through the expectations channel. Private speculators resist being fooled. They anticipate the interventions. An “intervention bias” results with an inefficiently high equilibrium volume of intervention which does not reduce the impact of shocks to the exchange rate. The model implies that the more independent the central bank the smaller and the more consistent the intervention efforts. An empirical illustration lends some support to the model.  相似文献

Concerns about U.S. competitiveness have increasingly focused the attention of policymakers on the workforce and mechanisms that could be used to enhance both the quality and quantity of human capital in the workplace. This article focuses on basic skills education of hourly workers, precisely the type of human capital which is likely to be most underprovided by the private market. Five questions are addressed: First, what is the nature of workplace education programs? Second, why do some firms provide workplace education programs while others do not? Third, what, if any, characteristics distinguish those firms that provide workplace education programs from seemingly comparable firms that do not? Fourth, what, if any, evidence can be found identifying the effects of these programs on the firms that sponsor them? Fifth, what policies appear most likely to stimulate additional workplace education?  相似文献
