A retrospective review of 406 suicidal gunshot wounds to the head, investigated at the Medico-Legal Laboratory of Pretoria, between 1997 and 2000 was performed. Fifty-seven percent of fatal suicidal firearm injury to the head occurred in the 21- to 40-year age range in both male and female victims. Eighty-two percent of all these victims of suicidal firearm fatalities to the head were male. Of the 406 cases, 63% were white, 31% were black, and 6% were of mixed ethnic and/or Asian decent. There was a slight increase in incidence around spring and autumn. Handguns were used in the majority of cases with shoulder weapons being used in 18 of the 406 cases. Ninety-two percent of the suicidal gunshot wounds to the head occurred indoors. A positive blood alcohol concentration was seen in 40% of cases. Of those examined, 81% were contact gunshot wounds. The trajectory was upward in 51% of cases and horizontal in 24% of cases. The right temple was the most common entrance gunshot wound site. Findings are in keeping with previously published literature. 相似文献

Psychiatric advance directives (PADs) statutes presume competence to complete these documents, but the range and dimensions of decisional competence among people who actually complete PADs is unknown. This study examines clinical and neuropsychological correlates of performance on a measure to assess competence to complete PADs and investigates the effects of a facilitated PAD intervention on decisional capacity. N=469 adults with psychotic disorders were interviewed at baseline and then randomly assigned to either a control group in which they received written materials about PADs or to an intervention group in which they were offered an opportunity to meet individually with a trained facilitator to create a PAD. At baseline, domains on the Decisional Competence Assessment Tool for PADs (DCAT-PAD) were most strongly associated with IQ, verbal memory, abstract thinking, and psychiatric symptoms. At one-month follow-up, participants in the intervention group showed more improvement on the DCAT-PAD than controls, particularly among participants with pre-morbid IQ estimates below the median of 100. The results suggest that PAD facilitation is an effective method to boost competence of cognitively-impaired clients to write PADs and make treatment decisions within PADs, thereby maximizing the chances their advance directives will be valid. 相似文献

Parents and parenting practices are often implicated as predictors of early childhood offending in criminological research, but little is known about the role of parents in adulthood in promoting or inhibiting criminal behavior. As juveniles mature into adult roles, parents also continue to mature and interact with their children in numerous roles throughout the life course. Unlike peers and romantic partners, parents are not easily discarded. Adults who have built a good foundation with their parents, then, possess additional social capital that has the potential to better adult life course outcomes, including criminal behavior. Social bonds formed within romantic relationships and stable employment have been the dominant factors identified within criminological literature in promoting criminal desistance, but in today's society with high rates of divorce and an unstable low-skilled job market, parents of origin may be an important stabilizing force in the lives of adults, particularly those lacking other conventional bonds. Using three waves of data from the Ohio Lifecourse Study, a project that spans some twenty-one years, the findings showed that strong relationships with parents are a significant predictor of criminal desistance for adult children, mainly through the emotional benefits these relationships have for the adult children. Furthermore, the data revealed that the adult child-parent relationship is a stronger predictor of desistance among the subjects with poor romantic relationship bonds. Implications for the life course theory are discussed. 相似文献

The demography of the legal profession has changed rather dramatically in recent decades, yet the consequences of a more racially and ethnically diverse pool of lawyers for the administration of justice have not received significant attention. The present research examines how the racial composition of the local legal profession affects one facet of criminal law: the sentencing of convicted defendants. Building on prior work in the fields of law, stratification, and mobility, we hypothesize that racial and ethnic disparities in sentencing are mitigated where the legal profession is more diverse. In line with this hypothesis, analysis of data from a sample of large urban counties taken between 1990 and 2002 shows that the black-white racial disparity in sentencing attenuates as the number of black attorneys in the county increases, net of the percent black in the county and other possible confounding variables. Comparable results are found for Hispanics. The findings are discussed in the context of a demographically changing legal profession and prior work on racial disparities in the justice system. 相似文献

This study utilizes a national sample of 3, 776 high-school students to test two theoretical models of school avoidance behavior. More specifically, this study examines the relationships between student avoidance and both school disorder (or, incivilities) and previous victimization experiences. Further, the study also examines whether the presumed effects of incivilities and victimization on avoidance operate indirectly, through student fear. Negative Binomial regression analyses showed that perceived disorder in the form of presence of gangs and previous bullying victimization are key sources of student fear. In turn, student fear is positively correlated with two distinct types of avoidance behavior. Interestingly, controlling for student fear does not dissolve the significant, positive effects of perceived gang presence and bullying victimization. 相似文献

Abstract: This report describes the identification of a merchant mariner who perished in 1948 when Northwest Airlines Flight 4422, a DC‐4 carrying 24 seamen and six crew members crashed into Mount Sanford, Alaska. Fifty‐one years later, a human forearm and hand were found close by the wreckage of the plane, prompting identification efforts using DNA and fingerprints. There were significant challenges to both the fingerprint and DNA analyses. The hand was badly desiccated, making fingerprint friction‐ridge detail almost invisible and the remains had been embalmed upon discovery, making DNA amplification difficult. We present the results of an interdisciplinary approach that successfully addressed these challenges and ultimately led to the identification of the remains. These efforts relied on efficient fingerprint rejuvenation and imaging techniques that improved print resolution, as well as new DNA extraction techniques optimized for aggressively embalmed remains. 相似文献

Two experiments examined the effects of multiple identification procedures on identification responses, confidence, and similarity
relationships. When the interval between first and second identification procedures was long (Experiment 1), correct and false
identifications increased, but the probative value of a suspect identification changed little; consistent witnesses were more
confident than inconsistent witnesses; and the similarity relationships between suspect and foils were unchanged. When the
interval between first and second identification procedures was short (Experiment 2), suspect identification rates changed
little, but foil identifications increased significantly; confidence for all identifications increased; consistent witnesses
were more confident than inconsistent witnesses; and similarity relationships changed such that witnesses were less likely
to identify the suspect as being the best match to the perpetrator. 相似文献

A qualitative study was conducted to better understand the factors that contribute to psychotropic medication (PM) overuse among children in the child welfare system in Kentucky, including barriers to providing psychosocial interventions that potentially minimize the need for PM. Semi-structured interviews were conducted with personnel in the Department of Community-Based Services (DCBS). Participants identified important areas to target for system-wide quality improvement efforts, which included improved exchange of health information, training, and communications on the use of PM, and measures to improve access to non-pharmacological psychosocial interventions to address the mental healthcare needs of children in the child welfare system. 相似文献

This paper sought the opinion of 200 Nigerians on their willingness to cooperate with the police during the Boko Haram crisis. Public perceptions of police effectiveness during the crisis, residence location, gender and religious affiliation were used as moderators. Data was analysed using an explanatory factor analysis and structural equation modelling. Results indicated a strong association between perceived effectiveness and willingness to report to the police with respondents who question the effectiveness of the police being less likely to be willing to report criminal activity about Boko Haram. Further to this, the impact of religion on willingness to report was at least partially mediated by perceived effectiveness of the police with the results showing that Christian respondents perceived the police as less effective. Females and those living in the north were significantly less willing to report criminal activity to the police. The findings are discussed in relation to the BH crises and directions for future research are given. 相似文献
