Although researchers have identified individual-level predictors of nonphysical bullying among children and youth, school-level predictors (i.e., characteristics of the school environment that influence bullying exposure) remain largely unstudied. Using data from a survey of 1,838 students in 21 Boston public high schools, we used multilevel modeling techniques to estimate the level of variation across schools in student reports of nonphysical bully victimization and identify school-level predictors of bullying. We found significant between school variation in youth reports of nonphysical bullying, with estimates ranging from 25-58%. We tested school-level indicators of academic performance, emotional well-being, and school safety. After controlling for individual-level covariates and demographic controls, the percent of students in the school who met with a mental health counselor was significantly associated with bullying (OR = 1.03, 95% CI = 1.01, 1.06). There was no significant association between school-level academic performance and perceptions of school safety on individual reports of bullying. Findings suggest that prevention and intervention programs may benefit from attending to the emotional well-being of students and support the importance of understanding the role of the school environment in shaping student experiences with bullying. 相似文献

Politics and the life sciences--also referred to as biopolitics--is a field of study that seeks to advance knowledge of politics and promote better policymaking through multidisciplinary analysis that draws on the life sciences. While the intellectual origins of the field may be traced at least into the 1960s, a broadly organized movement appeared only with the founding of the Association for Politics and the Life Sciences (APLS) in 1980 and the establishment of its journal, Politics and the Life Sciences ( PLS ), in 1982. This essay--contributed by a past journal editor and association executive director--concludes a celebration of the association's thirtieth anniversary. It reviews the founding of the field and the association, as well as the contributions of the founders. It also discusses the nature of the empirical work that will advance the field, makes recommendations regarding the identity and future of the association, and assesses the status of the revolution of which the association is a part. It argues that there is progress to celebrate, but that this revolution--the last of three great scientific revolutions--is still in its early stages. The revolution is well-started, but remains unfinished. 相似文献

The article assesses civil society in Putin’s Russia through the lens of the small social movement working against gender violence. Based on questionnaires distributed to movement organizations in 2008-2009, we find significant retrenchment among the NGO segment of the movement, adding evidence to the claim of Russia’s turn toward authoritarianism. However, this innovative, midlevel analysis--not the typical society-wide surveys nor the small number participant observation--also shows that the women’s crisis center movement has made some in-roads in transforming the state, revealing that some democratic opportunities remain at the local level. 相似文献

INTRODUCTION: Drug concentration measured in postmortem adipose tissue may or may not reflect antemortem concentration. To examine the possibility of whether the presence of basic drugs in adipose tissue is the result of postmortem change, we examined: tissues with and without livor mortis, concentration gradients within the adipose layer, and the stability of drug concentrations during the postmortem period. CASE REPORTS: Five drug-related deaths with case histories and analytical data are presented. Adipose tissues with and without livor mortis from the thigh area of the same decedent were analyzed for cocaine. The cocaine concentration of the tissue exhibiting 4+ livor was equivalent to the concentration observed in tissue without livor. Analyses of cross sections of adipose tissues containing cocaine and methamphetamine disclosed that drug concentrations were equally distributed throughout the layer, from just beneath the dermis to directly above the muscle. When morphine and temazepam concentrations were measured in adipose tissues collected from similar sites, but at different times, from the same cadaver, they remained essentially the same over 3 days (approximately 80 h). CONCLUSIONS: Since concentrations were the same in areas with and without livor mortis, the possibility of redistribution into adipose from blood or vascular channels is eliminated. The absence of a concentration gradient within the adipose layer rules out diffusion or permeation from muscle into the adipose layer, and the failure of morphine or temazepam concentration to change over time indicates that drugs in the adipose tissue are stable during the postmortem interval. Our findings support the notion that drugs identified in postmortem adipose tissue are there because of antemortem deposition and not because of any postmortem change or event. 相似文献

A former cocaine and methamphetamine abuser was continuously monitored with both sweat patch and urine testing for approximately 6 months. Thirteen sweat patches were applied and collected, five were positive for cocaine and/or methamphetamine, but all the urine specimens collected were negative at the analytical cut-off levels. The high incidence of false positive sweat patch tests in relation to the sensitivity, specificity, and efficiency of the sweat patch assay is discussed. Possible mechanisms, which can lead to false positive results, are presented. The results of our study raise further questions about the preferential use of the sweat patch in detecting new episodes of drug use in formerly chronic drug users. 相似文献

Bloodstain pattern analysis to determine the wound‐of‐origin of bloodstains is problematic with nonspecific patterns. In this proof‐of‐concept study, the authors examined a molecular approach to correlate bloodstains with injuries using the rat as a model. Specifically, investigations were conducted on the rat brain marker, rno‐miR‐124‐3p, with the QIAGEN miScript System and real‐time PCR analysis. Rno‐miR‐124‐3p was detected in brain homogenates diluted 100,000 times; in 3‐week‐old, room temperature stored, simulated brain–blood stains; and in bloodstains from head gunshot wounds collected with swabs and subsequently frozen for 9–18 months; however, rno‐miR‐124‐3p was not detected in whole blood. Proof‐of‐principle was demonstrated by the ability to distinguish bloodstains from a gunshot wound to the head versus bloodstains from a gunshot wound to the chest, by the testing of otherwise identical bloodstains from the two patterns for the presence of the marker. The results suggest a viable approach to a longstanding problem in casework. 相似文献

From which evaluative base should we develop public policies designed to promote wellbeing among different cultural groups in different circumstances? This article attempts to advance an objective, universal theory of cultural evaluation grounded in a eudaemonistic account of human wellbeing. The approach evaluates cultures on the success with which they enable societies to promote the wellbeing of individuals through provision of needs and capabilities within their given, determinate circumstances. This provides the basis for a normative functionalism capable of identifying and explaining cultural deficits. 相似文献

Decentralisation is commonly defended on the grounds that it will bring government closer to people, thereby creating political structures that are more transparent and accountable to poor and marginal groups in society. However, a problem that is well recognised in the decentralisation literature is that the devolution of power will not necessarily improve the performance and accountability of local government. Indeed, in many cases, decentralisation simply empowers local elites to capture a larger share of public resources, often at the expense of the poor. Reflecting on these relatively long-standing problems, an important strand of scholarship has argued that central government can play a central role in counterbalancing the forces that tend to disfavour the poor. In this article, we aim to inform this scholarship by reflecting on the interface between local government and local people in two Indian States: Andhra Pradesh (AP) and Madhya Pradesh (MP). Drawing upon 12 months of primary research, we argue that although the government of AP did not devolve power to the extent that proponents of decentralisation would have liked, its populist approach to certain forms of poverty reduction empowered the poor in ways that the more ambitious decentralisation agenda in MP did not. This, we argue, was due in part to the fact that MP's decentralisation process failed to challenge the well-entrenched power of the village chiefs, the sarpanches. But the discrepancy can also be explained in terms of the historical evolution of ‘development populism’ in AP. In particular, we argue that the strong performance of programmes aimed at subsidising rice for low income households and providing credit to women's ‘self-help groups’ (SHGs) was part of the State government's wider political strategy of enhancing and maintaining electoral support among women, scheduled castes and the poor. 相似文献
