Federal regulations governing human subjects research do not address key questions raised by incidental neuroimaging findings, including the scope of a researcher's disclosure with respect to the possibility of incidental findings and the question whether a researcher has an affirmative legal cuty to seek, detect, and report incidental findings. The scope of researcher duties may, however, be mapped with reference to common law doctrine, including fiduciary, tort, contract, and bailment theories of liability.  相似文献

African American and Latino youth who reside in inner-city communities are at heightened risk for compromised mental health, as their neighborhoods are too often associated with serious stressors, including elevated rates of poverty, substance abuse, community violence, as well as scarce youth-supportive resources, and mental health care options. Many aspects of disadvantaged urban contexts have the potential to thwart successful youth development. Adolescents with elevated mental health needs may experience impaired judgment, poor problem-solving skills, and conflictual interpersonal relationships, resulting in unsafe sexual behavior and drug use. However, mental health services are frequently avoided by urban adolescents who could gain substantial benefit from care. Thus, the development of culturally sensitive, contextually relevant and effective services for urban, low-income African American and Latino adolescents is critical. Given the complexity of the mental health and social needs of urban youth, novel approaches to service delivery may need to consider individual (i.e., motivation to succeed in the future), family (i.e., adult support within and outside of the family), and community-level (i.e., work and school opportunities) clinical components. Step-Up, a high school-based mental health service delivery model has been developed to bolster key family, youth and school processes related to youth mental health and positive youth development. Step-Up (1) intervenes with urban minority adolescents across inner-city ecological domains; (2) addresses multiple levels (school, family and community) in order to target youth mental health difficulties; and (3) provides opportunities for increasing youth social problem-solving and life skills. Further, Step-Up integrates existing theory-driven, evidence-based interventions. This article describes Step-Up clinical goals, theoretical influences, as well as components and key features, and presents preliminary data on youth engagement for two cohorts of students.  相似文献

While numerous surveillance and policing scholars argue that the rise of the surveillance society has normalized technological surveillance by police, the lack of empirical research makes it difficult to discern the true impact of risk management, security, and surveillance on police work. The present study uses in‐depth interviews and participant observation with two Canadian police agencies to explore the impact that police technologies have on police‐public interaction. From this analysis, we argue that the organizational shift toward risk‐oriented, intelligence‐led policing is not carried out on the ground. Instead, patrol officers often utilize technologies to legitimize the policing of the “usual suspects.”  相似文献

The career development literature published in 2008 is summarized and presented thematically: (a) professional issues, (b) career assessment, (c) career development, (d) career theory and concepts, (e) career interventions, (f) advances in technology, (g) employment, (h) international perspectives, and (i) research design and methodology. Traditional and emerging theories and practices are robust and vibrant.  相似文献

We test if the motivating potential of active work and the demotivating consequences of high-strain work can be explained by the “quality” of motivation experienced. Study 1, an experiment (N?=?205), revealed active work maintained intrinsic motivation and identified regulation (compared to baseline). High-strain work decreased these motivations. Moreover, demand was negatively related to mastery only at low control, through reduced intrinsic motivation. Demand was negatively related to task performance at low control, through reduced identified regulation. Study 2, an online survey (N?=?516 employees), revealed an energising effect of active work on intrinsic motivation and identified regulation, both of which had positive associations with job performance. A demotivating effect of high-strain work on intrinsic motivation was revealed, which had negative associations with job performance. In conclusion, internalised motivations are important mechanisms, through which active work protects and enhances mastery/performance, and through which high-strain work can deplete these outcomes.  相似文献

This research examined the direct and indirect relationships between core self-evaluations (via mental health) and emotional exhaustion originating from both the work and caregiving domains. The extent to which these relationships were moderated by control over work and care also was examined. Data came from 142 employed mothers in Australia who completed surveys at three measurement points each separated by four weeks. Results showed that core self-evaluations related positively to mental health which, in turn, related negatively to emotional exhaustion originating from work, but only when work control was high. Moreover, core self-evaluations related negatively to emotional exhaustion originating from care through improvements in mental health, but care control did not moderate this relationship. Overall, these findings contribute to a better understanding of how working mothers’ personal and work resources mitigate emotional exhaustion.  相似文献

Two proposed U.S. federal laws would provide explicit protection for lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) students in public schools. These federal laws follow actions by many states and school districts to define and implement laws or policies to protect the safety of LGBTQ students in schools. Research during the past decade has shown that LGBTQ youth are a vulnerable population, and that the negative school experiences of LGBTQ students often contribute to their vulnerability. This Social Policy Report reviews research relevant to these federal, state, and local laws and policies. Research on sexual orientation/identity development is reviewed, with attention to the growing numbers of youth that “come out” or disclose their LGBTQ identities to others during their school-age years. Schools are often hostile environments for LGBTQ students; this evidence is considered along with research on the consequences for compromised achievement and emotional and behavioral health. We then review strategies in education policy and practice that are associated with well-being for LGBTQ (and all) students.  相似文献
