Corporal punishment is a controversial practice used by the majority of American parents and is especially prevalent among African Americans. Research regarding its consequences has produced mixed results although it is clear that there is a need for considering the context within which corporal punishment is administered. To assess the impact of spanking, we employed an expanded parenting typology that includes corporal punishment. Longitudinal self-report data from a sample of 683 African American youth (54 % female) were utilized to evaluate the relative impact of the resulting eight parenting styles on three outcomes: conduct problems, depressive symptoms, and school engagement. Results from Negative Binomial Regression Models indicate that the effect of corporal punishment depends upon the constellation of parenting behaviors within which it is embedded and upon the type of outcome being considered. While it is never the case that there is any added benefit of adding corporal punishment, it is also the case that using corporal punishment is not always associated with poor outcomes. Overall, however, our findings show that parenting styles that include corporal punishment do not produce outcomes as positive as those associated with authoritative parenting. 相似文献

Despite the declining rate of teen pregnancies in the United States, academic and public health experts have expressed concern over the still relatively high rate of rapid repeat pregnancies among adolescents, particularly among minority youth. Using a sample of over 300 African American female adolescents, the current study used insights from the prototype/willingness model of adolescent risk behavior to explore this risk. More specifically, it assessed the relationship between entry into unwed motherhood during mid-to-late adolescence and changes in prototypes of unmarried pregnant teens. Further, it explored the extent to which these changing prototypes accounted for young mothers’ later contraceptive expectations. We tested the possibility that social images were affected not only by personal experience (the birth of a child) but also by the family and community context in which this experience took place. The findings show that the early entrance into teen motherhood was associated with a shift toward more favorable prototypes of unwed pregnant teens, but that this was only the case for young mothers in disadvantaged contexts. Given this, prototype changes helped to explain the link between teen motherhood and contraceptive expectations only for those in disadvantaged contexts. We discuss these findings in terms of their practical and theoretical implications. 相似文献

Previous research has documented that adverse life experiences during adolescence, particularly for ethnic minorities, have a long-term influence on income and asset attainment and that this relationship is largely mediated by educational achievement. We extend prior research by investigating three research questions. First, we investigate the extent to which community disadvantage, family factors and race/ethnicity each exert an independent influence on young adult socioeconomic attainment. Second, we examine whether youths’ educational attainment mediates these independent influences on socioeconomic attainment. Third, we test whether educational attainment ameliorates the negative influences of disadvantaged community and family conditions and race/ethnicity on socioeconomic attainment. We address these questions using multilevel modeling with longitudinal, prospective data from Waves 1 and 4 of National Longitudinal Study of Adolescent Health, which has a nationally representative sample of adolescents (N?=?13, 450; 53?% females). Regarding our first research question, our results indicated that African Americans, youth from disadvantaged communities, lower SES families achieve significantly lower levels of earnings, assets, and job quality during young adulthood. Second, we found that young adults’ educational level only partially mediate the influences of family and race/ethnicity influences on young adults’ socioeconomic attainment. Third, we found that young adults’ educational level buffered the influence of early socioeconomic adversities and accentuated the positive influences of family resources. Findings highlight the importance of social context as well as educational opportunities during childhood and adolescence for economic stability in early adulthood. 相似文献

Nonprofit child care centers are frequently observed to produce child care which is, on average, of higher quality than care provided in commercial child care centers. In part, this nonprofit advantage is due to different input choices made by nonprofit centers—lower child‐staff ratios, better‐educated staff and directors, higher rates of professional development for staff. Nonprofit centers may have an additional productivity advantage, due to unmeasured staff motivation and abilities or to better management of the production of good‐quality child care. However, where nonprofit and for‐profit child care firms compete in the same local markets, we speculate that this extra advantage should only appear where demand is sufficiently “thick” to permit a quality differentiation strategy to be financially viable for nonprofits. We estimate the effect of nonprofit status on quality, controlling for differences in financial resources available to the center, differences in the clientele served, and differences in staff and center inputs. In this conventional examination, nonprofit status has a moderately positive impact on quality. However, when we account for the unobserved heterogeneity and separate markets into “thick” and “thin,” a particularly strong nonprofit advantage is found in thick markets, but no productivity advantage for nonprofits is found in thin markets. This finding suggests a clear role for nonprofit organizations in improving the cost‐quality trade‐off faced by parents, but also identifies the market conditions that affect the ability of nonprofit managers to employ this advantage. © 2009 by the Association for Public Policy Analysis and Management. 相似文献

This study investigated genetic and environmental influences on the associations between mother–child relationship quality
(warmth and hostility) and adolescent conduct problems and cigarette use. Participants included 601 mothers and adolescent
twin pairs (aged 12–17 years). Mothers and adolescents provided separate reports of mother-to-child warmth and hostility.
A combined measure of mother and adolescent reported conduct problems was used while adolescents provided reports of their
cigarette use. Analyses were conducted using bivariate genetic analyses of correlated factors models and regression analyses
of monozygotic twin differences. Genetic influences were found for most ratings of the parent–child relationship, with evidence
of gender and/or rater-specificity for some measures. The relationship between mother–child hostility with adolescent conduct
problems and cigarette use was influenced by genetic and environmental effects. Evidence was found for shared environment
effects on the relationship between mother–child warmth and conduct problems. Examining monozygotic twin differences provided
further support for non-shared environmental influence on the relationship between mothers’ expressions of hostility and low
warmth and adolescent adjustment. Findings are discussed in relation to the interplay between genetic and environmental effects
underlying links between parent–child relations and adolescent behavior problems.

Ghana’s National Health Insurance Scheme, introduced in 2003, aims to remove financial barriers to health-care access and bridge the inequality gaps in health care. This paper reports on a study of the implementation process in four local government areas in southern and northern Ghana. The paper profiles key institutional actors and draws on qualitative interview data from 33 in-depth interviews. Findings highlight the gaps and challenges that have emerged in the implementation process. Issues of managerial capacity, inadequate and uneven distribution of medical facilities and health-care professionals, cost escalation, fraud and abuse, and reimbursement of providers threaten the sustainability of the scheme. 相似文献

In late-Habsburg Prague, in the years before the Great War, the members of the Zionist Student Association Bar Kochba were remarkably ambivalent regarding the “objective” constituents of “genuine” nationalism claimed by the national movements of that place and time: territoriality, “blood,” distinctive cultures, national languages, etc. As Zionists, they desired such “objective” national attributes for themselves, even as they remained fully aware that these were ultimately inapplicable to their Jewish reality. The article illustrates this complexity by examining how these Prague Zionists theorized the concepts of national lands, national homelands, and national rootedness. Their deep-seated ambivalence toward the territoriality of nations, then, has been in response to Jews’ particular condition in the Diaspora. It does, however, expose a broader tension manifested in some shape or form in other national movements: many of the concepts of what nationhood is are adopted from alien cultures and often from the very culture from which the national movement seeks to dissociate. 相似文献

Even the best functioning legal system will not function without committing errors. Court errors can be about questions of law and questions of fact. This paper discusses the implications of court errors for the behavior of the participating litigan's and the wider implications of unavoidable court errors for the performance of a legal system with respect to the selection of disputes. 相似文献
