Highly-publicized school shootings have heightened concern over school safety. This study examines the impact of school crimes
on campus policy. The administrators of 336 Texas middle and high schools were surveyed. Policy changes were related to parental
complaints about school crime policies and administrator perceptions that students felt less safe. School administrators should
base safety policies on strategies that have been evaluated for their effectiveness in reducing school crime and fear.

Brazil has an “African‐origin” population that is proportionally more than four times larger that of African Americans in the United States, but white Brazilians mostly dominate electoral politics. How do ordinary citizens explain this phenomenon? Drawing on a large‐sample survey of public opinion in the state of Rio de Janeiro, this article explores perceived explanations for nonwhite underrepresentation in the political arena. It also examines attitudes toward a particular black candidate, Benedita da Silva, to discern the state of negro identity politics. Most Brazilians in Rio de Janeiro cite racial prejudice to explain nonwhite exclusion, although whites do this less than nonwhites. Indicators of a racial undercurrent in political preferences suggest the importance of allegiances based on perceived common racial origins. Class is robustly associated with voting preferences, suggesting that, in contrast to the United States, class differences among nonwhites in Brazil could attenuate the success of negro identity politics. 相似文献

The continuing convergence of immigrants on New York City is a puzzle. On the one hand, the decline of the city's manufacturing sector and the growth of advanced services appear to provide little demand for immigrant labor; on the other hand, the deep penetration of immigrants into the city's economy has been paralleled by a deteriorating employment situation among native blacks. This article, seeks to unravel this puzzk in the light of two conflicting perspectives, the restructuring and the replacement labor hypotheses. The paper assesses each perspective using data from the 1970 and 1980 Censuses of Population and merged sampks of the June 1986 and 1988 Current Population Surveys. 相似文献

OBJECTIVE: To describe the death of a toddler after a therapeutic dose of dextromethorphan and its investigation. STUDY DESIGN: Case report, cytochrome P450 phenotype and genotype determination in the victim and post-mortem drug redistribution study performed in rats. RESULTS: A 20-month Asian male who received 3 mg of dextromethorphan once at 09:00 h and again at 22:00 h was found dead at 04:35 h. Post-mortem examination showed signs of early bronchopneumonia (bacterial cultures were negative); dextromethorphan and dextrorphan blood concentrations taken from the heart cavity were 500 ng/ml (1. 84 micromol/l) and 200 ng/ml (0.78 micromol/l), respectively. Despite the dextromethorphan level being almost 100-fold higher than expected after therapeutic doses, intentional or unintentional overdose was extremely unlikely; other potential causes were investigated. Post-mortem drug redistribution study performed in rats showed that dextromethorphan does not undergo extensive redistribution after death (6+/-5-fold increase) and could not explain the observed dextromethorphan level. The dextromethorphan/dextrorphan concentration ratio of 2.5 found in this toddler was compatible with a slow CYP2D6 metabolizer phenotype. However, the toddler exhibited a fast metabolizer genotype. Potential reasons for this discrepancy are discussed. CONCLUSION: CYP450 phenotypes derived from post-mortem blood levels should be interpreted with caution and preferably confirmed by a genotype analysis. 相似文献
