Scientific research has made major contributions to adolescent health by providing insights into factors that influence it and by defining ways to improve it. However, US adolescent sexual and reproductive health policies—particularly sexuality health education policies and programs—have not benefited from the full scope of scientific understanding. From 1998 to 2009, federal funding for sexuality education focused almost exclusively on ineffective and scientifically inaccurate abstinence-only-until-marriage (AOUM) programs. Since 2010, the largest source of federal funding for sexual health education has been the “tier 1” funding of the Office of Adolescent Health’s Teen Pregnancy Prevention Initiative. To be eligible for such funds, public and private entities must choose from a list of 35 programs that have been designated as “evidence-based” interventions (EBIs), determined based on their effectiveness at preventing teen pregnancies, reducing sexually transmitted infections, or reducing rates of sexual risk behaviors (i.e., sexual activity, contraceptive use, or number of partners). Although the transition from primarily AOUM to EBI is important progress, this definition of evidence is narrow and ignores factors known to play key roles in adolescent sexual and reproductive health. Important bodies of evidence are not treated as part of the essential evidence base, including research on lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth; gender; and economic inequalities and health. These bodies of evidence underscore the need for sexual health education to approach adolescent sexuality holistically, to be inclusive of all youth, and to address and mitigate the impact of structural inequities. We provide recommendations to improve US sexual health education and to strengthen the translation of science into programs and policy.  相似文献

The current study, using data from 374 African American students (59.4% female) in grades 7–12 attending a rural, southern county public school, addressed associations of self-efficacy, ethnic identity and parental support with “future education orientation.” Both gender and current level of achievement distinguished adolescents with differing levels of future education orientation. The strongest predictors of future education orientation were self-efficacy, ethnic identity and maternal support. Gender did not moderate these associations. Implications for future research include the need to conduct longitudinal studies and research that integrates quantitative and qualitative methods to elucidate further the nature and importance of future education orientation for African American youth. Also needed are policies and programs that facilitate school bonding and academic performance, as are efforts that focus specifically on enhancing the future education orientation and academic success of African American male adolescents.

Abstract

At the outset of the 2015 refugee crisis, Germany pursued an accepting asylum policy, potentially to mitigate its declining population. Austria, facing the same demographic challenges, closed itself to refugees. Differences in radical right-wing populism (RRP) in the two countries provide the basis for understanding their asylum policies. After the Second World War, Germany’s collective memory stigmatized far-right parties, while Austria’s did not. The radicalization spiral reproduces these differences today, allowing Austria’s Freedom Party to influence migration policy by pulling voters and mainstream parties to the right, while Germany’s RRP parties were unable to do the same before the crisis.  相似文献

Education policy affects communities across Canada. Changes in demographics, enrolment patterns, and pressures on education budgets have put school closures on the political agenda in many provinces. Implementing these policies is increasingly contested and conflict-ridden. Public administrators are at the cross-hairs of implementing evidence-based policies, based on authentic stakeholder input and engagement. This article examines two cases of school closure policy implementation in Ontario to illustrate the tension between these two important dimensions of public administration and challenges that must be overcome in this and other policy areas where evidence and engagement are increasingly important.  相似文献

Designing a system of regulation that will deliver defined policy objectives is not easy. This is particularly so when regulating new technologies, where challenges relating to uncertainty and risk, resource asymmetry, and regulatory disconnection are especially significant. By adopting a pluralistic, decentred approach to regulation that utilizes a range of soft‐law regulatory techniques, non‐state actors can contribute in a variety of ways to these special challenges. However, using non‐state resources in this way (either formally or informally) is not a panacea. Public trust and confidence in the regulation of risk is crucial in ensuring the viability of the control framework. Yet, it is difficult to maintain, not least because regulatory pluralism often envisages state and industry cooperation. Nevertheless, the involvement of non‐state actors, including industry, is important if the regulatory framework is not to hamper technological development or expose the public to unacceptable risks.  相似文献

Guided by an integrated theory of parent participation, this study examines the role community characteristics play in influencing a parent's decision to use voluntary child abuse prevention programs. Multiple regression techniques were used to determine if different community characteristics, such as neighborhood distress and the community's ratio of caregivers to those in need of care, predict service utilization levels in a widely available home visiting program. Our findings suggest that certain community characteristics are significant predictors of the extent to which families utilize voluntary family supports over and above the proportion of variance explained by personal characteristics and program experiences. Contrary to our initial assumptions, however, new parents living in the most disorganized communities received more home visits than program participants living in more organized communities. The article concludes with recommendations on how community capacity building might be used to improve participant retention.  相似文献
