The present study examined the relationship between participation in sports during adolescence and physical activity and subjective health in young adulthood. A sample of 8,152 (males = 50.8%, females = 49.2%) adolescents from the National Longitudinal Study of Adolescent Health were used. Results of the study showed that participating in an organized sport during adolescence was associated with higher levels of physical activity and better subjective health during young adulthood after controlling for participation in general physical activities (e.g., jogging, biking, skateboarding) during adolescence. Participation in sports during adolescence was associated with more positive self-beliefs 1 year later that, in turn, were associated with higher levels of moderate to vigorous physical activity and better subjective health 6 years later. Results suggest that positive self-beliefs partially mediate the relationship between adolescents’ participation in sports and two health outcomes in young adulthood: moderate to vigorous physical activity and subjective health. Findings highlight the utility of youths’ participation in organized sports for promoting healthy outcomes. Implications for policy and practice are discussed.

Given educational risks facing Mexican-origin children of immigrant parents, it is important to understand how aspects of the acculturation process influence Mexican-origin youth's educational success. Drawing from selective assimilation theory, this study examined how cultural orientations across myriad facets of acculturation were associated with the educational attainment of second-generation Mexican immigrant youth. The sample included 755 Mexican-origin youth (50% female) in the "Children of Immigrants Longitudinal Study." Results from structural equation models indicated that youth reporting greater facility in the English language and a stronger value on familism attained higher levels of education in young adulthood than did other youth. Parents' U.S. social ties and youth's value on early paid work were associated with less educational attainment. Innovative findings from this study indicate the importance of considering both Mexican and American cultural orientations across myriad facets of acculturation for understanding second-generation immigrant Mexican youth's educational attainment.  相似文献

Abstract

This article explores the ways in which city policymakers in Europe frame the reasons for provision of welfare services to migrants with irregular status. In the context of restrictive national legal and policy frameworks, the article explores a tendency toward municipal activism in extending access to services, providing a typology of six policy frames used by policy makers that identify the intended beneficiaries and stated policy aims. Drawing on interviews with local policymakers and documentary sources, the article contributes to our understanding of the reasons why some European cities provide services to this particular section of the migrant population.  相似文献

E‐governance comprises the use of information and communication technologies (ICTs) to support public services, government administration, democratic processes, and relationships among citizens, civil society, the private sector, and the state. Developed over more than two decades of technology innovation and policy response, the evolution of e‐governance is examined in terms of five interrelated objectives: a policy framework, enhanced public services, high‐quality and cost‐effective government operations, citizen engagement in democratic processes, and administrative and institutional reform. This summary assessment of e‐governance in U.S. states and local governments shows that the greatest investment and progress have been made in enhanced public services and improved government operations. Policy development has moved forward on several fronts, but new policy issues continually add to an increasingly complex set of concerns. The least progress appears to have occurred in enhancing democracy and exploring the implications of e‐governance for administrative and institutional reform. ICT‐enabled governance will continue to evolve for the foreseeable future providing a dynamic environment for ongoing learning and action.  相似文献

Despite interest in the role of religiosity in youth development and health behavior, few studies have examined these associations in sexual minority youth. Participants (n = 11,699) who were adolescents (wave 1) and young adults (wave 3) in the Add Health survey were used to examine proximal and distal religiosity by sexual identity group and to test group differences in associations between religiosity and alcohol use. Sexual minorities were less likely than heterosexuals to report a current religious affiliation. In young adulthood, heterosexual females reported significantly higher distal and proximal religiosity than heterosexual males and sexual minority young adults. From adolescence to young adulthood, religiosity in all three sexual identity groups (heterosexual, bisexual, gay/lesbian) significantly declined, with the largest effects found for the sexual minority groups. Distal and proximal religiosity scores were significantly associated with less alcohol use and less binge drinking among heterosexuals, but not among sexual minorities. Future studies of sexual minority youth and their religious contexts are suggested.

Passage of the Affordable Care Act (ACA) in the US increases demand for nurses and brings health care into the public sphere with all that entails, including public accountability and performance measurement. In the UK’s long-standing national healthcare system, revelations of several years of neglect and poor oversight at one hospital might have contributed to nearly 1,200 deaths. The resulting Francis Report cited, among many factors, undue emphasis on reaching national access targets and balancing budgets for substandard care. Scholars of emotional labor note these trends with interest, because emotional labor is essential to nursing practice. But is emotional labor a universal construct, or is it particular to cultural context? How much can be imported from one study to the next? We compare nurse job stress in individualist and collectivist countries and reveal a statistically significant relationship: The higher a country’s individualism index, the greater the frequency of emotional-labor-demanding job stress.  相似文献

In the wake of our nation's financial crisis, protection against insurer insolvency is more critical than ever to the insurance-buying public. All U.S. jurisdictions provide partial statutory protection in the event of insurer insolvency through the creation of various state insurance guaranty associations that are governed by statutes primarily based on a model act promulgated by the National Association of Insurance Commissioners. Guaranty associations are an integral part of each state's regulatory process for addressing insurer insolvency. Through a matrix of state-specific enabling statutes, state insurance guaranty associations levy and collect assessments from member insurers, pay statutorily defined “covered” claims, and defend against appropriate claims that are in litigation. Together with the domestic regulator of the insolvent insurer (usually the commissioner or superintendent of insurance) and the deputy liquidator (typically approved by the court presiding over the liquidation process and selected by the commissioner or superintendent of insurance as statutory liquidator), the guaranty association community (comprised of associations located in virtually each state in which a policyholder resides) functions as a unified system to manage and at least partially mitigate the impact of an insurer insolvency.  相似文献
