Observations of high velocity bloodspatter on adjacent objects   总被引:1,自引:0,他引:1  
In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides.  相似文献

Conclusion We have in this paper tried to set out a framework which can facilitate analysis of the current and future situation of traditional rulership in contemporary African society. Our presentation of a proposed model for such an analysis is no doubt still in its elementary stages of formation. Much more work needs to be done. Nevertheless, our analysis has revealed certain salient elements and uncovered certain unresolved issues. If traditional rulers genuinely care about their own future they will have to devise techniques of legitimation which not only endear them to the government and the non-traditional elites, but also, and more importantly, to the mass of the people. True, the original role of the traditional rulers may be no more; still, it may be possible to salvage what is left.  相似文献

With the rapid growth of cross-border competition among currencies, informed observers predict that the new monetary unions are virtually inevitable in many parts of the world. In fact, predictions of such alliances are misleading and almost certainly wrong. Monetary unions necessarily imply a measure of collective action in the issue and management of money. An alliance requires allies—other states with similar preferences and a disposition to act cooperatively. A survey of proposed monetary unions shows that willing partners among sovereign states are just not all that plentiful. Conceivably some governments could be attracted to less demanding forms of monetary alliance, depending on bargaining context. But prospects for many full new monetary unions are dim at best.  相似文献

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed.In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death.  相似文献

Law enforcement agencies and institutions of higher education have confronted increasing numbers of violent and destructive campus riots and disturbances over the past decade. Problematic is the fact that these riots typically have no underlying cause, other than students’ quest for excitement. Responding to gaps in the empirical literature about these events, this study used data from two waves of surveys to systematically examine those involved in a recurring problem event in a college town that was subject to a police crackdown. The analyses drew on survey responses from over eight hundred event participants in 2002 and 2003, and the results revealed that increased enforcement had a significant effect on crowd composition, including the gender and race of participants, repeat visitors, out-of-town participants, and perceptions about the subjects' overall experience. Implications for law enforcement and community strategies to decrease the size and destructiveness of such problem events are outlined.  相似文献
