Incorporating epidemiological and pathologic factors, a retrospective analysis of aortic injury and driving fatalities was conducted. To better understand the mechanism of injury, data were compiled for decedent demographics, autopsy and toxicology findings, and accident circumstances, with emphasis on directional impact. Review of the autopsy files of the Office of the Chief Medical Examiner in the State of Maryland in 2003 and 2004, identified 150 cases of aortic injury recorded in 537 autopsied drivers. Aortic lacerations occurred in 96% of the cases with aortic injury, two thirds of which were complete or near complete transections. A large percentage of cases involved a side impact collision. Consistent with extant research on frontal and lateral impacts, the majority of aortic injuries occurred at the ligamentum arteriosum. Also, the mechanism of aortic injury seems to be similar for side and frontal impact collisions, involving a combination of rapid deceleration forces along with chest and/or upper abdominal compression. This study emphasizes the importance of side impact collisions as a cause of aortic injury. Aortic lacerations have a high mortality rate and better motor vehicle design may prevent this type of injury.  相似文献

Suicide is a deliberate act of ending one's life. Suicide by use of any explosive device, when not involved in a terrorist act, is quite rare in occurrence when compared with other methods routinely utilized. In this paper, we present to the medicolegal community a case of an adult male who committed suicide with blasting caps and the subsequent extensive damage to the cranial hard tissue. Although the cause and manner of death were relatively straightforward, consultation with forensic anthropologists was requested for an anthropological trauma assessment of the highly fragmented skull. After the skull was cleaned and reconstructed, the analysis revealed similarities between blasting cap trauma to the head and high velocity gunshot trauma to the head. Therefore, in a case where some evidence may have been removed or destroyed, forensic analysis involving trauma of this magnitude could result in a misinterpretation of the true mechanism responsible for the osseous damage. In this case, cooperation among the law enforcement agency, coroner's investigators, the forensic pathologist, and forensic anthropologists provided a comprehensive death case analysis.  相似文献

This article explores the gender dynamics in a multidisciplinary research team, focussing particularly on the way gendered power struggles affect the production of knowledge. Gender-based conflicts over the relevance of gender to the research process threatened to silence all the women involved in the research: the researchers, the participants and the woman on the management team. As the research was exploring the under-representation of women in senior positions in organisations and their experiences of gendered processes at work, this silencing would have had particularly serious implications for the outcome of the project. During this conflict, power resources were mobilised by both women and men. The eventual resolution of the conflict ensured that women's voices were heard and their experiences made visible. This had a crucial effect on both the research process and the outcome of the research project and demonstrates the critical effect of gender on the knowledge that can be produced by research.  相似文献

Self-esteem plays a central role in mental health, yet not enough is known about how youth evaluate themselves as they move across adolescence. This study used a cross-sectional design to examine age and gender patterns in self-esteem and to explore how contemporary social influences relate to adolescent self-esteem. Self-reported influences on self-esteem involving the media, sexual harassment, body image, family and peer relationships, and emotional expression were evaluated with 93 boys and 116 girls in Grades 5, 8, and 12. Girls reported lower self-esteem than boys in early adolescence, and late adolescent boys reported lower self-esteem than younger boys. The predictors as a set accounted for a significant portion of the variance in self-esteem, while the best predictor of self-esteem varied by age and gender. Large gender differences were present for emotional expression, with boys becoming more restrictive across adolescence. Girls reported more negative body image and media influence scores than did boys in late childhood and early adolescence. Body image appeared to mediate the relationships between certain predictors and self-esteem for girls, while gender and grade appeared to moderate the relationship between media influence and self-esteem for girls and boys.  相似文献

This research was funded by the U.S.-Ukraine Research Partnership project, which began in November of 1999 when an agreement was signed between the National Institute of Justice (NIJ) and the Ukrainian Academy of Law Sciences (UALS). This partnership program was an integral part of the Gore-Kuchma Binational Commission, established in September 1996 to solidify the close ties between Ukraine and the United States. The increasingly global character of crime has created a mutual incentive for cooperation between the United States and Ukraine. In June of 1999, requests for proposals in the United States and Ukraine were concurrently announced by both NIJ and UALS. The proposals were to address the following crime areas: organized crime, corruption, drug trafficking, human trafficking, and economic crimes. The proposals were competitively reviewed by an expert working-group made up of both U.S. and Ukrainian representatives. The result was five U.S.-Ukrainian research teams, composed of twenty-two Ukrainian and five U.S. members. The size of each individual U.S.-Ukrainian team ranged from ten to three researchers. These teams met for the first time in November 1999 at a “kick-off” conference in Kiev, Ukraine. The greatest accomplishment of the conference was that researchers began the process of overcoming communication barriers and divergent methodological approaches to formulate a joint plan for their research. For this research, Layne worked with two Ukrainian research partners to jointly develop this paper. Khruppa was responsible for collecting Ukrainian data for the report and Muzyka supplied legislative expertise and background. Layne traveled to Ukraine (Kyiv and Kharkiv) four times over the course of two years and her Ukrainian counterparts came to the United States once. It was a challenge to collaborate across distance and language barriers, but a warm, collegial relationship developed and was maintained despite these obstacles.  相似文献

This article examines the subjective experiences of previously imprisoned women. Their retrospective narratives of prison life reveal overt behavioral and underlying structural tensions that create an atmosphere of fear and violence. Furthermore, attitudes of indifference between inmates and correctional staff often contribute to fostering an environment of neglect. The study, based on in-depth interviews with fifty-four female subjects, describes and analyzes several aspects of the socialization process for inmates as related by women on parole. The research shows that the “pains of imprisonment” for women are suffered to a greater degree than previously acknowledged. Prison for these women is a social world filled with anxiety and, perhaps, represents a punishment well beyond what the law intended.  相似文献

ABSTRACT

There is continuous pressure on public managers to adopt information and communication technologies (ICTs) to transform the way cities work. E-government research provides insights on the institutional, organisational, and individual factors that shape technology adoption and use. Yet most studies on small and medium sized cities use cross-sectional data or rely on small samples. We lack a systematic understanding of how technology use in smaller cities has changed over time and where these cities are lagging. Drawing from a multi-year, multi-method national study of city government technology use, we describe advancements and gaps in the enactment of a range of technologies, from social media to open data portals, and explore variation across city population, department type, and manager age. Our findings show that smaller cities still lag in the adoption of key features while local government managers are more inclined to adopt and positively perceive social media than traditional ICTs.  相似文献
