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

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 purpose of this study was to examine the relationship between job demands, job resources, and burnout, and to examine if burnout could predict both work and health-related outcomes among police officers. The participants were 223 Norwegian police officers, and data were collected using a questionnaire. The study was part of a national survey of both health care and non-health care professions. The overall level of burnout was low among police officers compared to other occupational groups tested in Norway. Both job demands and job resources were related to burnout, especially work-family pressure was an important predictor for all of the three burnout dimensions. Burnout predicted individual outcomes, such as psychosomatic complaints and satisfaction with life, as well as work outcomes, such as job satisfaction, intention to quit, and organizational commitment. Suggestions for potential interventions to reduce burnout and negative individual and organizational consequences are presented.  相似文献
