This study describes the risk factors associated with experiencing and committing sexual aggression among a sample of male and female adolescents. High school students completed a questionnaire containing a revised form of the Sexual Experiences Survey to assess sexual victimization and offending experiences. Ordinal regression equations were estimated separately for male and female students, regressing background characteristics, dating behaviors, and attitudinal scales on sexual victimization (for females) or offending (for males). Nearly half (48%) of the females report experiencing sexual aggression, and one-third (34%) of males admit committing this type of offending. Regression analyses show that the likelihood of reporting victimization/offending increases among females who report dating more frequently during the past month, among both males and females who report dating more different people during the past 6 months, and among older males. Females who report their religious affiliation as Protestants compared to those with no religious affiliation, and those planning to attend college are less likely to report victimization. Among the males, rejecting rape stereotypes and having more accurate legal knowledge regarding rape are related to reduced likelihoods of reporting sexual offending. Implications for improving sexual assault educational programs for adolescents are discussed.  相似文献

This study examines the ability of the Behavior Assessment System for Children, Self Report of Personality-Adolescent, 2nd edition (BASC-2-SRP-A) to predict trauma symptomatology as measured by the Child Report of Post-traumatic Stress among a sample of 59 male and 59 female adjudicated youth. Logistic regression revealed that clinically significant CROPS scores were predicted by BASC-2-SRP Social Stress and Somatization scale scores. A second logistic regression indicated that among youth with significant CROPS scores, gender was predicted by Sensation Seeking and Depression scale scores. Further, 47.4% (n = 56) of juvenile offenders’ CROPS scores were clinically significant, with females scoring significantly higher than males. Results endorse the validity of the CROPS and suggest that with additional analysis the BASC-2-SRP may also have the potential to identify juvenile offenders with a history of trauma.  相似文献

Although the courts have explicitly expressed concerns about the effects of public sentiment on juries in highly publicized cases, no research has isolated the degree to which jurors’ exposure to community outrage and/or prospective social interactions in the community independently influence judgments of guilt. In the current research, jury eligible undergraduates were randomly assigned to conditions in a 2 (negative defendant facts pretrial publicity (PTP): present vs. absent)?×?2 (community outrage PTP: present vs. absent)?×?2 (anticipated social interaction: present vs. absent) between subjects factorial design. In an online session, participants read articles containing PTP (or not), and two days later they arrived at the lab to serve as mock jurors in a murder case – before the trial they were instructed (or not) that they would interact with people from the community in which the case was taking place. Neither PTP containing extra-evidentiary facts about the defendant nor prospective interaction with the community had main or interactive effects on guilt measures; however, mock jurors rated the defendant as more likely to be guilty when they read information about community outrage and hardships on victims. These findings suggest future avenues of PTP research focusing on community outrage and victim impacts.  相似文献

Formalin-fixed tissues provide the medical and forensic communities with alternative and often last resort sources of DNA for identification or diagnostic purposes. The DNA in these samples can be highly degraded and chemically damaged, making downstream genotyping using short tandem repeats (STRs) challenging. Therefore, the use of alternative genetic markers, methods that pre-amplify the low amount of good quality DNA present, or methods that repair the damaged DNA template may provide more probative genetic information. This study investigated whether whole genome amplification (WGA) and DNA repair could improve STR typing of formaldehyde-damaged (FD) tissues from embalmed cadavers. Additionally, comparative genotyping success using bi-allelic markers, including INDELs and SNPs, was explored. Calculated random match probabilities (RMPs) using traditional STRs, INDEL markers, and two next generation sequencing (NGS) panels were compared across all samples. Overall, results showed that neither WGA nor DNA repair substantially improved STR success rates from formalin-fixed tissue samples. However, when DNA from FD samples was genotyped using INDEL and SNP-based panels, the RMP of each sample was markedly lower than the RMPs calculated from partial STR profiles. Therefore, the results of this study suggest that rather than attempting to improve the quantity and quality of severely damaged and degraded DNA prior to STR typing, a more productive approach may be to target smaller amplicons to provide more discriminatory DNA identifications. Furthermore, an NGS panel with less loci may yield better results when examining FD samples, due to more optimized chemistries that result in greater allelic balance and amplicon coverage.  相似文献

Native American (NA) youth's delinquency is one of the major problems that have been overlooked by criminal justice researchers and practitioners. To examine if negative family environment influences their delinquency with the mediating effect of negative emotion, this study analyzed structural equation modeling based on the General Strain Theory (GST). Using data regarding NA adolescents, this study found much evidence supporting GST. The results of the model with anger showed that anger was a mediating variable between family indifferences and delinquency, and the model with depression indicated that family indifferences increased delinquency through depression. However, some results in the model with anger and depression were not in accordance with GST hypothesis.  相似文献

The past year has seen a global upsurge of violent attacks by lone, mentally unstable individuals. The motivations for these attacks have varied and extremist ideological drivers are rarely ‘pure’, but mental health problems and personal grievances are common themes. Mentally ill and disenfranchised individuals may be vulnerable to extremist messages and propaganda because such beliefs can be a means of interpreting their social difficulties. Terrorist messages can also be adopted by psychotic people who are seeking to make sense of their symptoms. Most lone-actor attacks are preventable, if there is a system in place for identifying and intervening with antecedent behaviours, which include mental disturbances and the social problems that frequently accompany these conditions. Joint police-mental health models developed to assess and manage fixated persons can be applied to other forms of grievance-fuelled, lone-actor violence. This paper describes the establishment of such a service in Australia, and provides some preliminary data. It also discusses the role of mental health in the current security environment.  相似文献

Abstract: The examination of printing defects, or imperfections, found on printed or copied documents has been recognized as a generally accepted approach for linking questioned documents to a common source. This research paper will highlight the results from two mutually exclusive studies. The first involved the examination and characterization of printing defects found in a controlled production run of 500,000 envelopes bearing text and images. It was concluded that printing defects are random occurrences and that morphological differences can be used to identify variations within the same production batch. The second part incorporated a blind study to assess the error rate of associating randomly selected envelopes from different retail locations to a known source. The examination was based on the comparison of printing defects in the security patterns found in some envelopes. The results demonstrated that it is possible to associate envelopes to a common origin with a 0% error rate.  相似文献

The Mozambique Eyecare Project was an international partnership to implement and research eye health education in Mozambique and the Africa region. An optometry degree was developed at Universidade Lúrio, Mozambique. In addition, existing eye health workers were upskilled with training. Researchers from various disciplines evaluated the project and its potential for impact on eye health in the region. The body of evidence generated from the research provides useful lessons for development programmes in general, as well as specific lessons for delivering eye health education and service delivery models for low-income settings.  相似文献

The public administration literature once devoted great effort to identify the determinants of administrative intensity in organizations. While this literature has received some renewed attention, there remain questions about what aspects of organizational environments generate growth in administrative intensity, particularly as related to political oversight and external accountability mechanisms. This article aims to expand current theory on the determinants of administrative personnel and costs using data on four‐year public universities in the United States from 1998 to 2011, as this setting has received considerable criticism for perceived administrative bloat. Findings suggest that which political party is in control substantially influences both administrative costs and total personnel. These administrative levels, in turn, have a curvilinear relationship with student outcomes.  相似文献
