Five hundred seventy-eight community college and four-year state university students responded to questionnaires designed to assess judgments regarding O. J. Simpson's guilt, beliefs surrounding the case, general attitudes, and background information. Although African Americans were more likely to perceive Simpson as innocent than non–African Americans, correlation analyses revealed that, for the most part, the same predictors explained African Americans' and non–African American's judgments of guilt. Finally, set-wise hierarchical regression analyses indicated that case-related beliefs that Simpson abused Nicole Brown Simpson and that the system was biased against him accounted for more significant incremental variance than did demographic variables such as age and ethnicity, personal experiences, and general attitudes. The results suggested that the racial polarization emphasized in public polls does not reflect the diversity of beliefs that existed within both African American and European American populations.  相似文献

While the medical world aggressively pursues scientific knowledge about Alzheimer's disease, sufferers and caregivers live with this ailment, not as patients, but as people going about their lives, needing and providing care. This article reports explanations of Alzheimer's from the perspectives of African American family caregivers and sufferers. Data were collected from thirty‐six families using participant observation and focus group interviews. Although caregivers sought and used medical expertise, their explanations of Alzheimer's were not only nonmedical, but not necessarily explanations of illness per se. Alzheimer's was presented instead as a way of being, predominantly characterized by views of the sufferer as childlike and by issues of continuity/discontinuity, though some saw Alzheimer's as part of a larger picture.  相似文献

There is increased interest in the widespread dissemination of outcome performance data to secure enhanced strategic control of public sector organizations. This paper adumbrates the rationale for such schemes, and outlines the potential distortions induced by excessive reliance on outcome-related performance indicators, inferred from experience in the management control and Soviet literature. The paper gives an outline of the performance review process in the United Kingdom National Health Service, and presents the results of a case study of the impact of the publication of outcome performance data in the maternity services. The research detected many of the expected distortions arising from reliance on performance indicator schemes, and concludes that they may have significant dysfunctional consequences. The paper does not however advocate the abandonment of performance audit in the public sector. Instead, it warns that great attention should be given to the managerial incentives implicit in any strategic control scheme, and that the style with which the scheme is applied will have important bearings on its effectiveness.  相似文献

Interest in examining both the uncertainty and variability in environmental health risk assessments has led to increased use of methods for propagating uncertainty. While a variety of approaches have been described, the advent of both powerful personal computers and commercially available simulation software have led to increased use of Monte Carlo simulation. Although most analysts and regulators are encouraged by these developments, some are concerned that Monte Carlo analysis is being applied uncritically. The validity of any analysis is contingent on the validity of the inputs to the analysis. In the propagation of uncertainty or variability, it is essential that the statistical distribution of input variables are properly specified. Furthermore, any dependencies among the input variables must be considered in the analysis. In light of the potential difficulty in specifying dependencies among input variables, it is useful to consider whether there exist rules of thumb as to when correlations can be safely ignored (i.e., when little overall precision is gained by an additional effort to improve upon an estimation of correlation). We make use of well-known error propagation formulas to develop expressions intended to aid the analyst in situations wherein normally and lognormally distributed variables are linearly correlated.  相似文献

Summary. Long waiting times for non-emergency (elective) procedures are a central feature of the UK's National Health Service, with about 1 million people waiting for surgery at any one time. This paper develops empirical models of the demand for and supply of elective surgery which simultaneously determine waiting times. The models are tested by using a panel of annual data for 5499 small areas from 1991 to 1998. Supply and demand functions are estimated for all specialties combined and for seven individual specialties, using panel data methods that incorporate simultaneously determined variables. The elasticity of demand with respect to waiting time varies between specialties but is always quite small. The results are discussed in the light of UK Government policy initiatives designed to reduce waiting times substantially. The analysis suggests that these initiatives will not stimulate demand markedly and therefore stand a good chance of succeeding provided that adequate additional resources are made available.  相似文献

This article is about a method of teamwork in which both the therapist and the consultant are present in the same room as the family. It distinguishes between the therapeutic team of consultant and therapist and the therapeutic system of consultant, therapist and family. It outlines some particular advantages and disadvantages which are present when working in the same room as the family and emphasises the importance of the careful preparation and maintenance of the therapeutic team if its creative potential for the family is to be fulfilled.  相似文献

This study examines the durations of strikes in selected occupations of the public and private sectors of the U. S. economy in the late post-World War II period. It asks whether differences in the legitimacy of unions and the legality of strikes alter the speed with which strikes end. Also, it argues that a curvilinear relationship between the institutionalization of strikes and unions and the termination rates of strikes exists. Data support hypotheses linking both the distribution of power resources and the institutional setting to the termination rates of different types of strikes (e.g., strikes under different contract statuses and over different issues). In general, where strikes are moderately institutionalized and precedents are being set, strikes end more slowly; at very high or very low levels of institutionalization, strikes end more rapidly.  相似文献
