A man with no previous medical problems had two documented exposures to an insecticide containing the organophosphorous compounds chlordane and heptachlor. Six months to one year later, he began to experience neurological symptoms which progressed until his death. At autopsy, his brain showed classic findings of multiple sclerosis, and he had a severe peripheral neuropathy. Review of the literature indicates that the findings are not compatible with chlordane toxicity. Some of the factors to be used in determining the casual relationship between toxic exposure and disease processes are discussed.  相似文献

Routine activity theory has long been plagued by a heavy reliance on proxy measures of lifestyles, which typically include demographic variables that are regularly used as measures of lifestyle and behavior. This reliance on indirect measures forces researchers to suppose how and why these indicators are related to victimization risks. Using detailed measurements of activities and specific structural aspects of communities is clearly more desirable and beneficial when seeking to explain variances in victimization risks. This research advances theoretical understandings of victimization risks through an analysis of specific social activities, aspects of neighborhoods, and contribution of each to the risks of larceny victimization for college students. We find that greater specificity in measuring lifestyles is warranted, for it is not just leaving one's home and going out in public that increases one's risk for victimization (a typical finding of routine activity theory scholars), but where one goes and what one does that are the important larceny victimization predictors.  相似文献

The potential of consensus building is dependent upon overcoming difficulties associated with the challenges in getting parties to the table. This article builds a framework for understanding the factors and variables most fundamentally involved in the initiation of consensus-building efforts. Nine factors involved at the beginning of a consensus-building process are identified and outlined. The framework is structured on three major functions of the initiation phase: the definition of the problem, the structure of negotiation, and the motivation to participate.  相似文献

THE PRINCIPLE OF VOLUNTARY AGREEMENT   总被引:1,自引:0,他引:1  
There may be many perfectly good reasons, of a purely pragmatic sort, for policy-making by voluntary agreement between regulators and those whose conduct is to be regulated. Pragmatism aside, however, policy-makers characteristically claim that that strategy is also morally superior to legislative compulsion. That claim is incorrect. Voluntary agreement, as it is presently procured, does nothing to enhance the moral legitimacy of the policies thereby promulgated. Anything a government is morally entitled to do with voluntary agreement of that sort, it would be morally equally entitled to do without it.  相似文献

This study evaluates the assumption that deprivation among African Americans and racial inequality lead to black interracial homicide due to racial conflict and antagonism. Using refined race‐adjusted Supplemental Homicide Report data, Uniform Crime Report data and census data, we test an alternative hypothesis that draws on the macrostructural opportunity theory to assess and more accurately specify the relationship between structural characteristics and black interracial homicide. We find that first, the relationship between economic factors and black interracial homicide can be explained in large part by high rates of financially motivated crime such as robbery, and second, that economic factors are associated with financially motivated but not expressive black interracial killings. Analyses of black intraracial killings are performed for comparison purposes. Collectively, the findings suggest that conflict‐based explanations rooted in racial antagonism and frustration aggression may be premature.  相似文献
