This article examines the legacy of lynchings on contemporary whites' views of blacks as criminal threats. To this end, it draws on prior literature on racial animus to demonstrate the sustained influence of lynching on contemporary America. We hypothesize that one long‐standing legacy of lynchings is its influence in shaping views about blacks as criminals and, in particular, as a group that poses a criminal threat to whites. In addition, we hypothesize that this effect will be greater among whites who live in areas in America where socioeconomic disadvantage and political conservatism are greater. Results of multilevel analyses of lynching and survey data on whites' views toward blacks support the hypotheses. In turn, they underscore the salience of understanding historical forces, including the legacy of lynchings that influence contemporary views of blacks, criminals, and punishment policies.  相似文献

Although homeless youth face a higher risk of victimization and mental health problems, little is known about school victimization and mental health outcomes for school-attending homeless youth. This study examined the relationship between school climate and school-related victimization and mental health problems among homeless youth. Multivariate analyses were conducted to examine the relationship between school climate factors and school victimization, suicidal ideation, and depression tendency in a representative sample of 1,169 school-attending homeless youth in 9th and 11th grades in California. Findings show that school-attending homeless youth are at high risk of being victimized at school and have high rates of depression tendency and suicidal ideation. Positive school climate, especially perceived high expectations from teachers and safety in school, was associated with lower rates of school victimization and mental health problems. The role of supportive school climate in the lives of school-attending homeless youth is discussed and future implications are suggested.  相似文献

The contemporary policing literature contains numerous examples of partnerships between academic researchers and police agencies. Such efforts have greatly contributed to evidence-based policing by increasing the knowledge base on effective strategies. However, research has demonstrated that successful collaboration between researchers and practitioners can be a challenge, with various organizational and inter-agency factors presenting difficulties at various stages of the process. Additionally, applied research can oftentimes face implementation challenges when the time comes to convert research into practice. The current study contributes to the literature by discussing researcher/practitioner partnerships and program implementation in the context of a multi-city risk-based policing project in the United States. We conceptualize police interventions as contingent on four distinct phases: 1) problem analysis, 2) project design, 3) project implementation, and 4) project evaluation. In this project, the research partners were able to successfully complete each phase in certain cities while the project experienced difficulty at one or more phases in other cities. We discuss these disparate experiences, identifying factors that facilitate or impede successful completion of each step. Policy implications and recommendations for future risk-based policing interventions are discussed.  相似文献

Adverse childhood experiences are associated with a wide range of behavioral, health, and psychiatric deficits and have recently been used to study the development of serious offending careers. Unfortunately, this research paradigm has largely ignored forensic populations. This study utilized the adverse childhood experiences framework to examine the associations between exposure to violence, victimization, and total adverse childhood experiences on sexual homicide using a sample of 616 incarcerated adult male sexual offenders from Canada 85 of whom committed sexual homicide. Epidemiological tables of odds revealed that a gradient of adverse childhood experiences was associated with sexual homicide, but that the most significant risks were for offenders who had the most extensive abuse histories. In adjusted models, exposure to violence, victimization, and total adverse childhood experiences increased the odds of sexual homicide by 334%, 249%, and 546%, respectively. These effects intensified in models adjusted for childhood enuresis, cruelty to animals, parental abandonment, deviant sexual behaviors, poor self‐image, and sexual problems to 559%, 326%, and 849%, respectively. The adverse childhood experiences framework is a systematic way to organize the criminogenic developmental sequela in sexual homicide.  相似文献

Near repeat analysis has been increasingly used to measure the spatiotemporal clustering of crime in contemporary criminology. Despite its predictive capacity, the typically short time frame of near repeat crime patterns can negatively affect the crime prevention utility of near repeat analysis. Thus, recent research has argued for a greater understanding of the types of places that are most likely to generate near repeat crime patterns. The current study contributes to the literature through a spatiotemporal analysis of residential burglary and motor vehicle theft in Indianapolis, IN. Near Repeat analyses were followed by multinomial logistic regression models to identify covariates related to the occurrence of initiator (the first event in a near repeat chain) and near repeat (the subsequent event in a near repeat chain) events. The overall findings provide additional support for the argument that neighborhood context can influence the formation and context of spatiotemporal crime patterns.  相似文献

Recent drug-crime scholarship has underscored the importance of conducting disaggregated research that focuses on the consistencies and variations between subcategories of drug misuse and criminal activity and, further, how these associations may vary across sociodemographic and cultural boundaries. The research presented in this article used cluster analysis to independently classify male and female arrestees based on their arrest charges and substance-specific indicators of initiation, use, dependence, and treatment need. The data come from Pennsylvania's Substance Abuse and Need for Treatment Among Arrestees study conducted as part of the State Treatment Needs Assessment Program. Five groups were identified in both the male and female cluster analyses. The results reveal both important differences and strong similarities in the drug-crime typologies of male and female arrestees. Given these findings, implications are discussed for developing and targeting responsive treatment services that match the particular risks and needs of drug-involved offenders.  相似文献

Research shows that eyewitnesses often become more confident with their selections from a lineup over time, a problem labeled "confidence inflation." Wells et al. (1998) Law and Human Behavior, 22, 603-647 suggested that eyewitnesses provide a confidence statement immediately following their selection to capture an unadulterated measure of confidence. Three experiments tested the effectiveness of introducing such a statement to combat the effects of confidence inflation on mock-juror judgments. All experiments provided evidence that the attributions participants formed about the eyewitness' confidence inflation differentially impacted their judgments. Although mock-jurors generally discredited eyewitnesses who showed confidence inflation and sometimes lowered probability of guilt ratings for the defendant, a clear exception occurred when mock-jurors attributed the inflation to an epiphany. Use of post-identification confidence statements to decrease the impact of confidence inflation in the courtroom may be insufficient.  相似文献

Violence in schizophrenia patients may result from many factors besides the symptoms of schizophrenia. This study examined the relationship between childhood antisocial behavior and adult violence using data from the NIMH CATIE study. The prevalence of violence was higher among patients with a history of childhood conduct problems than among those without this history (28.2% vs. 14.6%; P < 0.001). In the conduct-problems group, violence was associated with current substance use at levels below diagnostic criteria. Positive psychotic symptoms were linked to violence only in the group without conduct problems. Findings suggest that violence among adults with schizophrenia may follow at least two distinct pathways-one associated with premorbid conditions, including antisocial conduct, and another associated with the acute psychopathology of schizophrenia.  相似文献
