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

Teaching Students How to Use Emotions as They Negotiate   总被引:1,自引:0,他引:1  
Given that emotions are inescapable and complex, how do you teach students how to deal with them? This article offers instuctors a practical approach. It suggests that instructors and students turn their attention away from emotions and toward a more limited set of core emotional concerns that stimulate many emotions. The article describes ways to teach students how to use these core concerns as tools to understand the emotional terrain and to stimulate helpful emotions.  相似文献

Abstract: As federal policy‐makers revise and update the Bank Act, any change should be seen in the context of public policy towards financial institutions in Canada. Rather than being condemned to repeat history, both policy‐makers and potential bank entrepreneurs would be well advised to re‐examine the Report of the Inquiry into the Collapse of the ccb and Northland Bank (August 1986), chaired by the Honourable Willard Z. Estey. Public policy for financial institutions faces the challenge of reconciling competing interests. Since 1867, Canada has experienced a nationally controlled banking system that is highly stable (i.e., few bankruptcies) and that has enabled in‐flows of capital needed for national economic development. The Canadian Commercial Bank failure raised a fundamental challenge to the government's policy agenda. When asked what the government's position should be, the three officials recommended the rescue package. All three participants from the political side advised against it. Future policy must learn the lessons from this important and atypical moment in Canadian financial history. Sommaire: Alors que les decisionnaires federaux revoient et mettent à jour la Loi sur les banques, toute modification devrait être envisagée dans le contexte de la politique gouvernementale visant les institutions financières au Canada. Plutôt que d'être condamnés à répéter les mêmes erreurs, les décisionnaires et les banquiers potentiels feraient bien mieux de réexaminer le Rapport de la commission d'enquête sur la faillite de la Banque commerciale du Canada et la Norbanque (août 1986), présidée par l'honorable Willard Z. Estey. La politique gouvernementale concernant les institutions financières a la tâche difficile de réconcilier des intérêts opposés. Depuis 1867, le Canada connaît un système bancaire contrôléà l'échelle nationale qui est très stable, ayant enregistré peu de faillites, et qui a permis des rentrées de fonds nécessaires au développement économique national. La faillite de la BCC a lancé un défi fonda mental au programme de politique gouvernementale. Lorsqu'on leur a demandé quelle devrait être la position du gouvernement, les trois responsables ont recommandé le programme de renflouement. Les trois participants du secteur politique ont conseillé le contraire. Les futurs décisionnaires doivent tirer des leçons de cet évènement important et exceptionnel dans l'histoire financière canadienne.  相似文献

Retention of offender DNA samples serves an important quality assurance role for forensic DNA laboratories. Consistent with the principles of confidentiality underlying the establishment of the state and national DNA databases, safeguards are in place to protect the DNA samples from unauthorized use.  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
