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

Abstract: This article focuses on competition for votes between parties, as it existed in Western Europe in the period of the direct election to the European Parliament in 1989. Following earlier research by Van der Eijk and Niemöller, an instrument is introduced to measure the probability of party choice of EC citizens which establishes the likelihood of respondents to vote for any of the nationally relevant options/parties. A number of substantive conclusions about political parties'competitive performance result from this research. First, a single mechanism seems to structure electoral competition in all EC member-countries. Second, the competitive performance of political parties is not affected by their governmental status, their ideological position, and the degree of politicisation of the electoral environment. And third, parties'competitive performance is strongly affected by the degree of uniqueness of their electoral potential, their mobilising capacities, their ideological extremity and their sheer size. 相似文献

Abstract: The policy community approach to policy analysis has been developed from ideas expressed by Richardson and Jordan in 1979. The approach is increasingly used to identify the key actors and groups of actors who make policy decisions, to analyse the interactions between the groups and to hypothesise about the types of outcomes achieved. The approach aids analysis in policy contexts which cut across the boundaries of individual organisations in the policy process, across the public and private sectors, and beyond national boundaries. This paper evaluates several expositions of the approach with reference to an analysis of science policy in Australia and suggests typological refinements which enhance its explanatory capacity. 相似文献

As we explained there is really little a priori reasoning for a clear prediction that authoritarian regimes will incur more foreign debt. In fact, some other empirical literature reveals that such regimes will face a higher supply price for such debt. Anderson presents a study of a single year using an admittedly crude measure of authoritarianism that finds that such regimes do issue more debt.This study provides a fuller examination of the empirical relationship between foreign debt and the nature of the polity's regime. Utilizing a continuous democracy variable and a continuous political liberty variable, it tests the relationship between debt and political variables. It finds little empirical support for the thesis that democracy or autocracy influence foreign debt levels. Generally the continuous variables are not significant if we use a linear in the logs specification. While a linear specification obtains results more consistent with the idea that level of democracy decreases debt, it also obtains results even less favorable to the idea that extreme forms of autocracy increase debt. 相似文献

In principle, reporting by state and local governments to thefederal government is essential to the design and implementationof national policy. In practice, reporting often engenders resentmentof federal intrusion and is often dismissed as a waste of stateand local resources. Is reporting useless? Does it strengthenthe federal government at the expense of state and local governments?We asked federal, state, local, and site officials about thevalue and burden of five specific reporting systems in elementaryand secondary education. Common assumptions about reportingdid not correspond to respondent reactions. Both value and burdencascade through the intergovernmental system, reaching policymakersin all governments. Although critics seldom discriminate betweentypes of reporting, we found that reporting designed to improvecompliance with federal standards evoked different judgmentsof value and burden than reporting designed for assistance.These results suggest some new approaches to federal policygoverning the collection of information and to the design ofindividual reporting systems. 相似文献
