Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.  相似文献

Dual-credit courses expose high school students to college-level content and provide the opportunity to earn college credits, in part to smooth the transition to college. With the Tennessee Department of Education, we conduct the first randomized controlled trial of the effects of dual-credit math coursework on a range of high school and college outcomes. We find that the dual-credit advanced algebra course alters students’ subsequent high school math course-taking, reducing enrollment in remedial math and boosting enrollment in precalculus and Advanced Placement math courses. We fail to detect an effect of the dual-credit math course on overall rates of college enrollment. However, the course induces some students to choose four-year universities instead of two-year colleges, particularly for those in the middle of the math achievement distribution and those first exposed to the opportunity to take the course in eleventh rather than twelfth grade. We see limited evidence of improvements in early math performance during college.  相似文献

This research note presents three newly interconnected and expanded datasets on interest groups’ (IGs) access to the Swiss political decision‐making process: (1) extra‐parliamentary committee seats occupied by IGs (1980, 2000, 2010), (2) parliamentary (committee) seats occupied by IG representatives (1992‐2015), and (3) consultation replies submitted by IGs (2008‐11). We show that the Swiss system of interest intermediation adapted to the multiplication and organizational consolidation of citizen groups, which defend non‐producer interests and do not provide selective benefits to their members (e.g. environmental groups). The share of access granted to citizen groups has increased in both the administration and parliament, across all federal departments and most legislative committees. Moreover, citizen groups benefit from a larger share of access in the recently revitalized parliament, compared to the administration. This suggests that economic groups’ decline in power is also related to the rise of citizen groups.  相似文献

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.

This article examines the relationship between leadership and public value, which is particularly challenging in a context of explicit contest and conflict. The theoretical framework is illustrated through a case study of policing rural crime. The study reveals that the police worked with multiple and competing publics rather than a single homogeneous public, and that part of their leadership role was to create and convene a public space in which different voices and divergent views could be expressed. The study notes that research needs to pay attention to the loss and displacement of public value, not solely its creation and recognition. The need to convene multiple publics required the police to lead, as part of a leadership constellation, and with political astuteness. The findings have wider relevance for other public services, and for studies of leadership and public value at the intersection between the state and civil society.  相似文献

Although the use of truth and reconciliation commissions (TRCs) has grown considerably over the last 3 decades, there is still much that we do not know concerning the choice and the structuring of TRCs. While the literature has focused primarily on the effects of TRCs, we examine the domestic and the international factors influencing the choice of a commission in sub-Saharan Africa from 1974 to 2003 using pooled cross-sectional time series. We find that states which adopted a TRC prior to South Africa were generally repressive centralized regimes which used the truth commission as political cover. However, since South Africa’s TRC, democratizing states have been more likely to adopt a truth commission as a form of transitional justice.

这项研究探讨香港与上海两地青年的公共政策或社会责任、子孙或家庭责任、个人责任的觉识对其照顾、接纳和承担照顾父母的意愿的效应.研究结果显示:(1)对政府或社会的养老政策责任的觉识愈高者则照顾父母的意愿明显地愈高;然而,对老年人的自立生活具愈高的觉识者,其照顾父母的意愿却愈低;(2)对倡导尊敬老年人的觉识愈高和对老年人的自立生活的觉识愈低者,其接纳照顾父母的意愿愈高;(3)对政府责任的觉识愈高者和对个人责任的觉识愈低者,其承担照顾父母的意愿愈高.文章同时就倡导两地照顾或供养父母的政策启示进行讨论.  相似文献
