Rarely is the informational data required for the analysis of resource allocation decisions known with precision; uncertainty in such data is the rule, and not the exception. The conventional approach relying on data averaging, even when coupled with sensitivity analysis, limits the insights obtainable. Concepts of decision analysis under uncertainty are applied here to a controllable, Markov resource-allocative model. Proper application of these concepts provide the preferred framework for resolving informational data uncertainties. 相似文献

Through a 1979 survey of 89 Illinois judges, the present study attempts to assess how various social, political, and occupational
factors influence judicial attitudes toward criminal sanctioning. Specifically, our analysis examined the relative impact
of background characteristics (e.g. age, community context) versus occupational variables (e.g., years on the bench, former
prosecutor and/or defense attorney) on five sanctioning scales: rehabilitation, punishment, capital punishment, punishing
white-collar offenders, and the treatment of juvenile delinquents. The analysis revealed that political orientation was the
most important variable examined. Political ideology was found to be related to all but one of the sanctioning scales (punishing
white-collar offenders). In contrast, the social and occupational variables generally were not significantly related to judicial
attitudes on the purposes of sentencing. 相似文献

This article examines the impact on British trade unions of the break in relations with the government, the economic recession and labour market developments in the 1980s. The shift towards a programme of 'labour exclusion' is related to specific policies designed to weaken trade unions and liberalize labour markets. A close investigation of data on union organization and activity indicates that, despite evident reversals, a full-scale de-institutionalization of industrial relations is not occurring. However, the links between government policies and longer-term socioeconomic trends pose severe challenges for union revival. The article concludes with some considerations on the future prospects of union-government relations. 相似文献

The authors report on a case of a dicygotic female twin pair, one of them containing a T/C heteroplasmy in two (heart and brain) of five analysed organs at position nt204 of the HV2 region. Results and especially the evidence of an unequal distribution of the heteroplasmy are discussed. 相似文献

In contrast to typical autoerotic fatalities, when death is due to asphyxia mostly by mechanical compression of the neck, atypical autoerotic accidental deaths (AADs) involve sexual self-stimulation by other means such as electrocution or inhalation of chemical agents. Especially in lethal cases of volatile substance abuse (VSA), a differentiation between suicide or sexually or nonsexually motivated accident is often complicated in practical casework. Considering the small number of AADs involving chemical substance abuse reported in the literature, the number of unreported cases seems to be very high. We report about 5 lethal cases of VSA; analysis was performed using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS). When headspace sampling is not performed at autopsy, the analysis of volatile substances can be very complicated. In 2 cases, an AAD was diagnosed considering findings at the scene, reconstruction of the event, and discussion of the circumstances of the death. These findings demonstrate the importance of VSA in atypical autoerotic asphyxia. Therefore, in cases of suspected lethal inhalational intoxications, as a matter of principle, headspace asservation should be performed at autopsy and an autoerotic motivational background should be taken into consideration for differential diagnosis. 相似文献
