Comparison of a suspected biter's dental arches with the patterned injury of a bite mark is especially difficult when the bite occurs in an anatomic location with a small radius of curvature or with complex or compound curves. The authors present two case reports in which human skin was used as a template for the reproduction of a bite. In one case the victim's skin was used; in the other, the skin of a anatomically similar person was used. The use of inked dental casts, photography, and transparent overlays significantly reduced the errors common to analysis of bite marks in these highly curved areas.  相似文献

In motorcycle accidents involving two riders, medicolegal identification of the driver is necessary when one or both riders die. It is particularly important in the latter case, because the survivor almost always insists that he or she was not driving. One characteristic injury that distinguishes the driver from the passenger is inguinal contusion-laceration (accompanied internally by pelvic fracture). This injury, caused by collision of the pelvis with the fuel tank, identifies the driver.  相似文献

The Department of Defense has taken steps in recent years to improve outcomes for victims of domestic violence who reside on military installations. In 2000, the Defense Task Force on Domestic Violence was established, a military‐civilian group of experts charged with improving the military's effectiveness in addressing domestic violence in the Armed Forces in a variety of areas including offender accountability, coordination between military and civilian communities, and changing the military climate around domestic violence. This article will provide an overview of the Task Force, its work during the past three years, and its recommendations.  相似文献

This research addresses the assumption that “general deterrence” is an important key to enhanced compliance with regulatory laws. Through a survey of 233 firms in several industries in the United States, we sought to answer the following questions: (1) When severe legal penalties are imposed against a violator of environmental laws, do other companies in the same industry actually learn about such “signal cases”? (2) Does knowing about “signal cases” change firms’ compliance‐related behavior? It was found that only 42 percent of respondents could identify the “signal case,” but 89 percent could identify some enforcement actions against other firms, and 63 percent of firms reported having taken some compliance‐related actions in response to learning about such cases. Overall, it is concluded that because most firms are in compliance already (for a variety of other reasons), this form of “explicit general deterrence” knowledge usually serves not to enhance the perceived threat of legal punishment, but as reassurance that compliance is not foolish and as a reminder to check on the reliability of existing compliance routines.  相似文献

In the presented oversight model, in which a regulatory agency may collude with regulatees, a watchdog organization may scrutinize the agency’s decision-making and find evidence speaking for collusive behavior. Found evidence is of a specific, stochastic quality. Courts will overturn the administrative decision when the evidence presented in court exceeds a minimum quality standard set by the political principal. Lowering the quality standard increases the odds of finding evidence of sufficient quality and, hence, leads to increasing collusion deterrence and to a lower probability of acquitting collusive administrators (type I error), but also to a higher probability of convicting an innocent administrator (type II error). It is shown that, when welfare-maximization gives rise to an interior solution, the welfare-maximizing standard of evidence is lower than the one that merely minimizes the costs of legal errors without taking deterrence costs into account, but will imply incomplete deterrence. However, conditions can and will be identified under which both error cost minimization and complete deterrence coincide with welfare-maximization.  相似文献

The population-adjusted rate of teenage suicide in King County, Washington, was reviewed for the 26 years from 1959 to 1984. For the entire period, the rate did not change significantly. An abrupt change did occur during the middle of this period, but, for reasons discussed in the text, this may well represent a change in procedures and philosophy of death certification rather than a real change in rate. Reasons for the apparent discrepancy with national statistics are discussed.  相似文献
