Do city governments generally behave in keeping with the assumptions underlying the incremental model when they allocate their resources among competing activities? That is to say, do they try to maintain everyone's historical “fair share” of the budget in order to minimize disputes among rival participants in the decision process? Earlier studies have lacked sufficient data to address this question. However, with data from 105 West German cities, the present study is able to provide an answer. The resource allocation behavior of many of those cities seems to conform with the incremental model's assumptions. Yet for other cities, major changes in expenditure patterns from one year to the next are common. The differences in the variability of expenditure patterns across the cities studied are far from random. They are systematically associated with certain characteristics of the municipal environment. These associations, in turn, offer plausible hints about the process that leads to change in cities' spending patterns.  相似文献

A limited number of recent empirical studies suggest that inmates suffer from high rates of serious mental illness. Different explanations are offered depending on the type of institution: jail or prison. The literature is based largely on urban samples and does not offer comparisons of rates across types of institution within a single study. The present study examined a random sample of 213 jail and prison inmates in a rural state using the Diagnostic Interview Schedule (III-R). Among jail inmates there was little evidence of high rates of serious mental illness, suggesting the criminalization of mental illness may not be as evident in rural settings as urban areas. Among prison inmates, however, high rates of mental disorders were found, supporting previous findings in urban and rural jurisdictions. Implications of the findings are discussed in the context of a consolidated correctional system.  相似文献

The causes of death of 53 severely to profoundly developmentally disabled patients who died in an intermediate care facility were reviewed. Respiratory disease, predominantly pneumonia and aspiration, accounted for 72% of deaths. Seven patients died of nonrespiratory causes, and in 8 patients, no cause of death could be determined, even after a complete autopsy or investigation. The median age at death was 20 years. The weights of these patients' organs at autopsy were lower than those for normal individuals of the same age. The lifespan of these severely impaired individuals continues to be significantly shortened, even with improved methods of care.  相似文献
