Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.  相似文献

The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.  相似文献

The concentration of thyreoglobulin (tg) was determined for death caused by hanging, strangulation by ligature, and throttling. Cases of sudden death (traumatic aortic rupture, penetrating wounds of the heart) were used for comparison. The mean values in cases of hanging (149.9±202.3 ng/ml), strangulation by ligature (193.1±173.3), manual strangulation (561.6±173.9) are distinguishable from violent acute deaths (23.3±27.6) and living healthy individuals (17.3±16.1). By means of statistical comparisons, significant differences were found between throttling and strangulation by ligature and between throttling and hanging (adjusted P<0.001). In connection with examination of the bodies high tg values can be regarded as a vital reaction in obstructive asphyxia.  相似文献

A growing body of evidence shows that minorities are disproportionately the targets of police brutality, but important theoretical questions about the causes of that inequity remain unanswered. One promising line of research involves structural‐level analyses of the incidence of police brutality complaints; however, existing studies do not incorporate variables from alternative theoretical explanations. Drawing on the community accountability hypothesis and the threat hypothesis, we tested the predictions of two prominent structural‐level explanations of police brutality in a study of civil rights criminal complaints. The study included cities of 150,000+ population (n = 114). The findings reveal that two community accountability variables—ratio percent Hispanic citizens to percent Hispanic police officers and the presence of citizen review—were related positively to police brutality complaints, partially supporting that perspective. Two threat hypothesis measures of threatening people—percent black and percent Hispanic (in the Southwest)—were related positively to complaints, as predicted. The relative degree of support for the two hypotheses is assessed.  相似文献

A number of recent studies have explored the consequences ofinterracial peer effects on the academic and social performanceof minority students. This article contributes to that discussion,focusing, however, on perceptions rather than behaviors. Theanalysis suggests that exposure to white peers is associatedwith declining perceptions of racial justice among black andLatino high school students. While cautioning against causalinterpretations of this finding, the article suggests that theintegrationist aims of Brown v. Board of Education will notbe satisfied without more thoughtful and vigorous desegregationefforts.  相似文献
