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

Our aim was to test the hypothesized relationships between trauma exposure and alcohol-related problems, mediated by PTS symptoms, moderated by prior trauma exposure and help-seeking. Participants were 244 members of a private university who were enrolled or employed at the school on the date of a campus shooting. Online measures were distributed via e-mail in October 2014, and included the AUDIT, BTQ, PCL-5, and self-report measures of trauma exposure and counseling services utilized. The overall moderated mediation model examining the indirect effect of exposure to trauma on alcohol-related problems through PTSD symptoms, moderated by prior trauma and help seeking was significant, β(SE) = .310(.3554), p = .0001. This study highlights the importance of crisis interventions following trauma exposure.  相似文献

In response to the increasing numbers of mentally ill persons placed under the care of correctional institutions, community-based diversion programs have been established to address the unique needs and challenges of this vulnerable population. Given that legal personnel may serve as gatekeepers in placement decisions, and the lack of existing research examining their attitudes toward offenders with mental illness, the present study aimed to evaluate perceptions of dangerousness and treatment need among a sample of judges, prosecutors, and public defenders across the state of Mississippi. While controlling for age, results of a factorial MANCOVA revealed that public defenders, relative to both judges and prosecutors, endorsed more compassionate attitudes about defendants with mental illnesses. Furthermore, political ideology did not significantly influence attitudes toward mentally ill offenders. While judges and prosecutors endorsed more negative stereotypes about mental illness and perceived mentally ill defendants as a greater risk to the community, mean scores across groups suggested moderately positive attitudes overall. Study limitations, implications for correctional mental health providers, and directions for future research are discussed.  相似文献

Depending upon specific situations, some victims of sexual assault provide vaginal samples more than 36-48 h after the incident. We have tested the ability of commercial and in-house Y-STR systems to provide DNA profiles from extended interval (> or =3 days) postcoital samples. The commercial Y-STR systems tested included the AmpFlSTR Yfiler (Applied Biosystems), PowerPlex Y (Promega) and Y-PLEX 12 (Reliagene) products whereas the in-house systems comprised Multiplex I (MPI) and Multiplex B (MPB). Three donor couples were recruited for the study. Postcoital cervicovaginal swabs (x2) were recovered by each of the three females at specified intervals after sexual intercourse (3-7 days). Each time point sample was collected after a separate act of sexual intercourse and was preceded by a 7-day abstention period. As a negative control, a precoital swab was also recovered prior to coitus for each sampling and only data from postcoital samples that demonstrated a lack of male DNA in the associated precoital sample was used. A number of DNA profile enhancement strategies were employed including sampling by cervical brushing, nondifferential DNA extraction methodology, and post-PCR purification. Full Y-STR profiles from cervicovaginal samples recovered 3-4 days after intercourse were routinely obtained. Profiles were also obtainable 5-6 days postcoitus although by this stage partial profiles rather than full profiles were a more likely outcome. The DNA profiles from the sperm fraction of a differential lysis were superior to that obtained when a nondifferential method was employed in that the allelic signal intensities were generally higher and more balanced and exhibited less baseline noise. The incorporation of a simple post-PCR purification process significantly increased the ability to obtain Y-STR profiles, particularly from 5- to 6-day postcoital samples. Remarkably an 8 locus Y-STR profile was obtained from a 7-day postcoital sample, which is approaching the reported time limit for sperm detection in the cervix.  相似文献

Inference of human geographic origins using Alu insertion polymorphisms   总被引:4,自引:0,他引:4  
The inference of an individual's geographic ancestry or origin can be critical in narrowing the field of potential suspects in a criminal investigation. Most current technologies rely on single nucleotide polymorphism (SNP) genotypes to accomplish this task. However, SNPs can introduce homoplasy into an analysis since they can be identical-by-state. We introduce the use of insertion polymorphisms based on short interspersed elements (SINEs) as a potential alternative to SNPs. SINE polymorphisms are identical-by-descent, essentially homoplasy-free, and inexpensive to genotype using a variety of approaches. Herein, we present results of a blind study using 100 Alu insertion polymorphisms to infer the geographic ancestry of 18 unknown individuals from a variety of geographic locations. Using a Structure analysis of the Alu insertion polymorphism-based genotypes, we were able to correctly infer the geographic affiliation of all 18 unknown human individuals with high levels of confidence. This technique to infer the geographic affiliation of unknown human DNA samples will be a useful tool in forensic genomics.  相似文献

Interest in legal innovations, particularly in the criminal law realm, often centers on an innovation's emergence, but not its subsequent diffusion. Typifying this trend, existing accounts of the prison's historical roots persuasively explain the prison's “birth” in Jacksonian‐Era northern coastal cities, but not its subsequent rapid, widespread, and homogenous diffusion across a culturally, politically, and economically diverse terrain. Instead, this study offers a neo‐institutional account of the prison's diffusion, emphasizing the importance of national, field‐level pressures rather than local, contextual factors. This study distinguishes between the prison's innovation and early adoption, which can be explained by the need to replace earlier proto‐prisons, and its subsequent adoption, particularly in the South and frontier states, which was driven by the desire to conform to increasingly widespread practices. This study further attributes the isomorphic nature of the diffusion to institutional pressures, including uncertainty surrounding the new technology, pseudoprofessional penal reformers and their claims about competing models of confinement, and contingent historical factors that reinforced these institutional pressures. This study illustrates the importance of distinguishing between the motivations that initiate criminal law innovations and those that advance their diffusion.  相似文献

Since the major British banks first purchased computers in the 1960s, they have been concerned with the security challenges that these machines presented. One of the most potent risks was TEMPEST, the discovery that computers emitted radiation which could reveal the content of information processed by them, even if it had been encrypted. Archival material recently uncovered within the Bank of England’s archives from the mid-late 1970s is presented here to provide a first look at how the Bank evaluated the credibility of the threat posed by TEMPEST and how it sought to manage this new risk.  相似文献
