In today's law enforcement community, one of the most vital tools an officer can possess is personal body armor. However, a recent Department of Justice investigation has raised important questions regarding the protection actually afforded officers through the use of personal body armor, and the current test methods used to assess the armor. Test results show that most Zylon-containing vests showed deformations in excess of the 0101.04 Standard's 44 mm backface signature limit. Such increased deformation can lead to serious injuries, including backface signature injuries, which have occurred in the field. Although the vest is successful in containing the round, it is not effectively dissipating the energy enough to prevent large amounts of vest deformation at the area of impact. Therefore, open, penetrating wounds occur even though the bullet did not penetrate the vest. The objective of the current study was to further define the backface signature injury through the use of case studies and laboratory experiments. Following the case study investigation, backface signature testing was conducted using a clay medium based on the NIJ 0101.04 Standard. The final component of this research involved the use of post-mortem human specimens (PMHS) for further investigation of the backface signature injury. Although the underlying cause of backface signature injuries is unknown, energy density is likely to play a role in the mechanism. Energy density (E/a) is defined as the energy per unit area and has been previously used in less lethal skin penetration research. Further research into the underlying causes of backface signature injuries is necessary. In addition to armor testing, the study of law enforcement personnel who have been shot while wearing soft body armor is also a valuable tool for determining the effectiveness of certification standards. Finally, it is important for medical personnel to recognize the backface signature injury and document this as a type of injury separate from blunt trauma or penetrating trauma behind armor injuries. Detailed knowledge of the injury, including the depth of the wound, would be beneficial to the scientific community. 相似文献

American Indian and European American women’s definitions and perceived causes for domestic violence were examined. Attitudes
towards violence and battering as it relates to the self were measured with two scales. As predicted, results indicated American
Indian women and European American women held different conceptualizations of what constitutes domestic violence and different
notions concerning the cause of domestic violence. Also, American Indian women were more attuned to external causes for violence,
while European American women referred to internal explanations for such violence. Differences in social and psychological
histories of violence and attitudinal orientations toward violence were indicated. Legal and health system changes are recommended
in order to combat violence in Indian country.

The transitional justice literature highlights various trade-offs involved in the choice and implementation of lustration as a transitional justice measure in Central and Eastern Europe. This article examines how international legal body rulings on lustration laws have interpreted rule-of-law versus justice concerns. The European Court of Human Rights and the International Labour Organization have explored possible information problems, due process violations, employment discrimination issues, and bureaucratic loyalty concerns within the context of lustration. Three findings emerge from their legal rulings. First, contrary to popular notions, international legal bodies are not antilustration. The institutions are engaging with questions regarding the fair implementation, not the legality, of lustration laws. Second, the prioritizing of justice concerns during the transition efforts is highlighted as a way to lay a strong democratic foundation. Third, the organizations have emphasized the importance of placing rule of law in historical context, thereby situating post-Communist societies within other posttotalitarian regime-building narratives. 相似文献

This article compares various models of ethics education and how these models are employed by both medical schools and law schools. The authors suggest ways in which each profession can enhance their ethical teaching and argue that ethics education in both medicine and law should combine the best elements of each education model, thereby producing graduates who are more knowledgeable and appreciative of ethical issues in practice. 相似文献

There is currently no accurate method to identify vaginal epithelial cells uniquely. This study aimed to use a cell extraction procedure compatible with routine forensic sampling methods, and to investigate the expression of cytokeratin (CK), estrogen receptor-alpha (ERalpha), and phosphodiesterase 5 (PDE5) in order to distinguish between skin, buccal, vaginal, and external penile epithelial cells. Seminal fluid samples were also examined. Epithelial cell samples were fixed in formalin, embedded in agarose, and processed using histological methods. Antigen-antibody reactions were detected using the DAKO Envision+ detection system. CK was present in all cells from all five sources confirming the origin of cells as epithelial. Both ERalpha and PDE5 positively labeled vaginal, buccal, and skin epithelial cells. Although an antigen unique to vaginal epithelial cells was not identified, we have described a cell extraction procedure for use in the immunohistochemical detection of a wide range of antigens, an approach compatible with forensic diagnostics. 相似文献

The Kansas v. Hendricks (1997) decision, in which the Supreme Court authorized post-sentence civil commitment for certain sex offenders, appeared to be constitutionally legitimized by limiting the class of offenders eligible for this special form of civil commitment to those who are "unable to control" their dangerousness. Nowhere in the available record, however, did the Court elucidate what they meant by this notion of volitional impairment. This study sought to examine factors that legal professionals (n=43), psychologists (n=40), and mock jurors (n=76) deem most relevant to a determination of sex offender volitional impairment. Participants, who were randomly assigned to a sexual predator commitment or an insanity hearing context, read a series of 16 vignettes that described a pedophilic offender and included combinations of variables hypothesized to be related to judgments of volitional impairment. Results suggested that participants, who as a group made remarkably high estimates of likelihood of future sexual violence, considered verbalization of control, history of sexual violence, and the context of the hearing as highly relevant to determinations of volitional impairment. Implications for policy and practice are explored. 相似文献
