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

Misidentification syndromes have been studied from a variety of perspectives, including phenomenological, biological, and nosological approaches. More recently, misidentification syndromes have been studied from a psychiatric-legal perspective, especially with regards to the problem of dangerousness. Capgras syndrome and other syndromes of misidentification can lead to hostile mood and subsequent physical violence. Little attention has so far been devoted to children as the objects of the psychotic person's misidentification delusion(s). We provide a review of cases from the anglophonic literature that have children as the misidentified objects, add three new cases, and then discuss the relationship between misidentification and potential harm to these children.  相似文献

Postmortem changes in sulfide concentrations in body tissues were examined in autopsied rats exposed to hydrogen sulfide concentrations of 550 to 650 ppm, and in nonexposed rats and humans. Analyses were made by gas chromatography, following an extractive alkylation. Sulfide concentrations in the blood, liver, and kidneys of rats increased in both the exposed and nonexposed groups, depending on the lapse of time after death. On the other hand, the lung, brain, and muscle showed little or no change in sulfide concentration with elapse of time after death. The data obtained from human tissues were almost the same as those for rats, except data for blood, in which no or little increase of sulfide was observed.  相似文献

We develop a model of the peace dividend and use it to predict the fiscal consequences of a reduction in the demand for military spending. The model is based on the assumption that the political process responds to political demands and costs in a way that maximizes net political benefits. The predictions of our model on how a peace dividend will be allocated over nonmilitary spending, tax relief, and deficit reduction is tested against the experience of eight major wars in United States history.  相似文献

A case of kidnapping involving the concept of paternity testing is described. The couple arrested and charged with kidnapping stated the child in their possession was their biological daughter. Serological tests were performed on liquid blood samples in an effort to determine if the couple could have been the biological parents of the child. Two genetic inconsistencies were discovered in the 15 blood marker systems analyzed.  相似文献
