Identification of the driver in two-rider motorcycle accidents. Inguinal contusion-laceration as an indication of the driver 总被引:1,自引:0,他引:1

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 effectiveness of harsher sanctions for domestic violence offenders is an important topic given legislative trends in “getting tough” with these offenders. This article takes a rare look at felony domestic violence, specifically felony assaults on female intimates, with an analysis of whether conviction, jail, and imprisonment are related to the odds of subsequent charges among 353 male defendants from twenty-four Ohio trial courts of general jurisdiction. Each defendant was followed up for two years after his original case was closed and his sentence (if any) was served. Conviction and jail sentences were both related to significantly lower likelihoods of recharging for intimate assault, but prison sentences were not related to these odds. These findings are discussed in relation to the potential importance of reducing short-term opportunities for violence in order to prevent future harm. 相似文献

Ministerial reshuffles are complex exercises requiring careful handling. A frequent occurrence in British government, their significance is usually seen in political terms. Prime Ministers attach great importance to maximizing the political advantages to be gained from them. This factor is the chief determinant of their logistics, the principal characteristics of which are secrecy in advance and the speed with which ministerial changes are executed. These features - as much as the frequency of ministerial changes per se - may disrupt the policy process and have serious implications for minister-civil servant power relations. Such problems could be alleviated by giving ministers advance notice of changes of post. The institution of a process of ministerial handovers would strengthen the position of incoming ministers by making them less dependent on their officials, upon whom they rely heavily for initial briefing at present. 相似文献
