Sudden death due to undiagnosed central nervous system tumors is an uncommon, but well-described occurrence. Most of the tumors in these circumstances are supratentorial and occur in a wide spectrum of ages. Brainstem tumors are more rare and occur predominantly in the pediatric and adolescent populations. We present the case of a 48-year-old man who died suddenly and unexpectedly of a brainstem glioma. This case is unusual because of his age and the paucity of antecedent symptoms.  相似文献

Municipal Support for Social Entrepreneurship   总被引:3,自引:0,他引:3  
This study examines how cities help social entrepreneurship—the activity of private individuals and organizations taking initiative to address social challenges in their communities. Based on a national survey and in-depth interviews among jurisdictions with populations over 50,000, the authors find that municipalities help social entrepreneurs by increasing awareness of social problems, and by helping them to acquire resources, coordinate with other organizations, and implement programs. Nearly three-quarters of cities provide active or moderate support, which is positively associated with the perceived effectiveness of nonprofit organizations in their communities.  相似文献

This article examines several recent trends in environmentalpolicy that may have important effects over the next decadeon federal-state relations and on the nation's environmentalquality. It focuses on the Environmental Protection Agency'sefforts to "reinvent" environmental regulation and to encouragecommunity-based environmental protection as a more effectiveand acceptable approach to environmental policy. We considerthe extent to which these new directions are likely to improverelations between the federal government and states, localities,and the private sector, and to achieve desired levels of environmentalprotection in the United States. The new approaches are highlypromising; yet they also face significant barriers to implementation.Congressional reform of the key statutes could lend much-neededsupport to such efforts.  相似文献

Despite that prisons in the United States (and other high-income countries) have witnessed an increase in the proportion of older inmates, and that prison populations exhibit high rates of psychiatric illness, there is limited knowledge on the nature of older inmates’ psychological health and use/provision of psychiatric care. The present study addresses these gaps, analyzing a nationally representative sample of 1,907 male and female older inmates (age range = 50–84 years; M = 56) housed in U.S. state and federal prisons. The results highlight: (a) the prevalence of psychological issues among older prisoners; (b) factors associated with certain mental disorders and symptoms of mental health issues; (c) the prevalence of psychiatric treatment before and during imprisonment for those with (and without) reported psychological health issues; (d) similarities and differences between male and female older inmates in relation to psychological health, factors associated with psychological issues, and the use/provision of psychiatric care. Discussion points toward recommendations for managing inmate mental health, as well as direction for further research on older inmate mental health and psychiatric care.  相似文献

Farmers in Canada are older and more capitalized than ever before. Meanwhile, farmland values continue to rise. These forces together are generating unprecedented shifts in farmland relations, marked by increasing reliance on rental tenure and the rise of hybrid owner–renter consolidating farmers. This paper explores these dynamics in Ontario and asks how they are impacting on-farm agroecological stewardship. To do so, we begin with a review of the land and property relations literature as well as farmland and agricultural change in Ontario. We then briefly review agroecological issues and concepts that are important for linking on-farm agroecological health to aformentioned farmland and agricultural changes. From here, we use survey, interview and soil sample data collected from grain farmers across Ontario to elucidate relatively new shifts in land tenure and use dynamics. We argue that this complex set of forces is interacting to produce an appealing set of conditions for financial investors, while restricting access to farmland for less-capitalized farmers. We then show how these shifts are divesting capital and attention from agroecological health. We conclude with a reflection on how the state has been mediating and contributing to these dynamics, and urgently call for land policy that prioritizes social and ecological principals.  相似文献

Although a considerable amount of research has highlighted the link between interpersonal victimization and adverse psychological and behavioral health, a paucity of research has examined and compared the effects of multiple forms of victimization in the same study. There is also a limited understanding of the underlying individual factors (e.g., emotional processes) that might link experiences of victimization to psychological and behavioral health adversities. To address these gaps, the author used a nationally representative sample of 19,422 Canadians aged 15 years old or older to examine the effects of different types of victimization on psychological and behavioral health outcomes, and to determine whether these associations are mediated by perceived stress. Results revealed that some victimization types (i.e., personal, household/property, cyberbully, ex-partner physical/sexual and emotional abuse) had statistically significant adverse effects on psychological and behavioral health outcomes (i.e., self-report mental health, life satisfaction, satisfaction with safety from crime, and alcohol/drug abuse). Results also revealed that perceived stress mediated the association between some victimization types and psychological, but not behavioral, health outcomes. Discussion points toward the utility of examining multiple victimization types, as well as other converging individual factors or adversities, in explaining psychological and behavioral health outcomes.  相似文献
