Although adolescents often participate in multiple extracurricular activities, little research has examined how the breadth of activities in which an adolescent is involved relates to school-related affect and academic performance. Relying on a large, multi-ethnic sample (N = 864; 55.9% female), the current study investigated linear and non-linear relationships of 11th grade activity participation in four activity domains (academic/leadership groups, arts activities, clubs, and sports) to adolescents’ sense of belonging at school, academic engagement, and grade point average, contemporarily and in 12th grade. Results of multiple regression models revealed curvilinear relationships for sense of belonging at school in 11th and 12th grade, grade point average in 11th grade, and academic engagement in 12th grade. Adolescents who were moderately involved (i.e., in two domains) reported a greater sense of belonging at school in 11th and 12th grade, a higher grade point average in 11th grade, and greater academic engagement in 12th grade, relative to those who were more or less involved. Furthermore, adolescents’ sense of belonging at school in 11th grade mediated the relationship of domain participation in 11th grade to academic engagement in 12th grade. This study suggests that involvement in a moderate number of activity domains promotes positive school-related affect and greater academic performance. School policy implications and recommendations are discussed.  相似文献

Forensic Technicians provide crime scene investigation services and are exposed to stressful violent crimes, motor vehicle accidents, biological or chemical hazards, and other appalling imagery. Forensic Technicians would likely experience physical and psychological stress after exposure to trauma, and security vulnerabilities similar to Sworn Police Officers. The perceived availability of mental health resources, job-related physical, psychological stress, and traumatic experiences of both Forensic Technicians and Sworn Police Officers from California law enforcement agencies were investigated using a self-reported survey. Responses were evaluated for any significant differences in the perceived stress, job-related physical stress, and resulting psychological impact affecting the participants. The survey contained a mix of True/False, Circle/Check the Appropriate Box, or Likert Scale (1–5) responses. The results were evaluated statistically and discussed. Results indicated Sworn Police Officers and Forensic Technicians have different on-duty stress levels, but similar off-duty stress levels. Nearly two-thirds of 54 job-related stressors were not significantly different between the two occupations. However, Forensic Technicians reported more adverse effects in 17 physical and psychological job-related activities compared with Sworn Police Officers. Forensic Technicians reported lower awareness levels and availability of agency mental health support services than were reported by Sworn Police Officers. This study reports for the first time an unexpected outcome that perceived and job-related psychological stress is greater for Forensic Technicians than Sworn Police Officers. Possible reasons for this disparity will be discussed as well as stress management tools that should be implemented to reduce health risk factors for both career professionals as well as increase public safety.  相似文献

Both leadership and public value are increasingly seen as concepts highly relevant to public administration, not only because of complex societal challenges but also as ways to address pluralistic interests in society. This article explores in detail the varied conceptualizations of public value and of public leadership. Furthermore, we argue that political astuteness provides an important conceptual linkage between leadership and public value, enabling actors to read, understand and foster coalitions around diverse and sometimes competing interests. In this introduction to the symposium, we analyse the different conceptualizations of public value, of leadership, and also show how the six articles explicitly or implicitly draw on the linking concept of political astuteness. The article assesses how the six articles of the symposium contribute to each of these three concepts.  相似文献

This paper examines the long‐term effect of project‐based housing assistance—public housing and private assisted housing—on work, earnings, and welfare receipt. We use the Panel Study of Income Dynamics–Assisted Housing Database to identify women ever living in project‐based assisted housing and to create comparison groups using propensity scores. Analyses show no evidence that moving into this type of assisted housing is associated with sustained reductions in employment rates, work hours, or earnings. Although welfare rates decline, they remain higher for assisted housing recipients compared with nonrecipients. Overall, these findings align with those of recent experimental and nonexperimental studies that include other forms of housing assistance and cover different time periods. © 2009 by the Association for Public Policy Analysis and Management.  相似文献

Conscious policy and program support for the resettlement of refugees in regional and rural areas is a relatively recent trend in Australia. Resettlement is a complex process that hinges on the establishment of viable communities. This review suggests that its outcomes, especially for refugee communities, are potentially mixed. However, an appropriately resourced, well managed and well planned refugee resettlement program can potentially provide beneficial outcomes for refugees and host communities. This article draws on existing empirical data and contributions made at a VicHealth Roundtable in late 2007 to thematically explore the challenges facing rural and regional resettlement programs. Given that settlement is a dynamic process and the approaches to rural and regional settlement are evolving, this article provides 12 propositions for a more effective and integrated approach to policy and practice.  相似文献

The 1934 Communications Act established a dual system of federaland State telecommunications regulation. The act gave the FederalCommunications Commission (FCC) authority to regulate interstateand foreign telecommunications but not intrastate communications,a market reserved for the states. As part of its move to deregulatethe telecommunications market in the 1970s, the FCC sought toextend its jurisdiction by preempting state regulatory authorityover telecommunications activities traditionally consideredintrastate. In 1986, however, the U.S. Supreme Court, in itsdecision in Louisiana Public Service, restricted federal preemptionof state laws and reinforced the dual regulatory system. Withthe break-up of AT&T, the FCC has renewed its preemptionactivities, claiming that the preemption is necessary in orderto foster an efficient nationwide telecommunications system.Several cases now pending in federal courts will test the breadthand depth of the Supreme Court's holding in Louisiana PublicService, and thereby, the future of the dual regulatory system.  相似文献

This article describes a nationwide empirical study that will be undertaken during the next three years into the newly emerging phenomenon of genetic discrimination. In particular, the study aims to investigate the nature and extent of genetic discrimination in Australia across three key perspectives: consumers, third parties and the legal system. Further, the study aims to examine the social and legal implications of genetic discrimination, with a view to making recommendations for use in the Australian legal and policy context. It is anticipated that the data produced from this multifaceted investigation will assist in identifying areas where legal or other reforms are required. It will contribute significant baseline data for facilitating ongoing assessment of the nature and extent of the problem, as well as for longitudinal evaluation of the impact and effectiveness of any reforms which may be introduced in the future to address the issue.  相似文献
