Components of nursing home (NH) culture change include resident-centeredness, empowerment, and home likeness, but practices reflective of these components may be found in both traditional and “culture change” NHs. We use mixed methods to examine the presence of culture change practices in the context of an NH’s payer sources. Qualitative data show how higher pay from Medicare versus Medicaid influences implementation of select culture change practices, and quantitative data show NHs with higher proportions of Medicare residents have significantly higher (measured) environmental culture change implementation. Findings indicate that heightened coordination of Medicare and Medicaid could influence NH implementation of reform practices.  相似文献

The emphasis in class research remains on the structural aspects of class, class processes are neglected. This paper focuses upon some relational and normative aspects of class through an examination of social divisions produced and constructed within middle class families’ choices of childcare. Working with data from two contrasting settings in London (Battersea and Stoke Newington) three issues are addressed in the paper; the extent to which childcare arrangements both substantively and structurally position children differently within long term educational careers; the ways in which the use of choice in a market system of child care and education, works to produce patterns of social closure that quietly discriminate via the collectivist criterion of class and racial membership; and the ways in which child care choices also point‐up and perpetuate subtle distinctions and tensions of values and lifestyle within the middle class, between class factions. Concepts drawn from the work of Bourdieu are deployed throughout.  相似文献

ABSTRACT The analysis of a set of data consisting of N short (≤20 observations each) multivariate time series, where the observations are irregularly spaced and where observations for the different components of each multivariate series are observed at different times, is discussed. With the increased use of automatic recording devices in many fields, data such as these, which are of course samples from smooth response curves, are becoming more common. In this application, which was a clinical trial comparing two cements for use in hip replacement surgery, the key to the analysis was in recognizing that the interest lay in the degree to which the five curves representing a patient's vital signs deviated from baseline (i.e., normal for that patient) during surgery. This enabled the statisticians to define appropriate response variables. The analysis included Rosseeuw's (1984) technique for the identification of multivariate outliers and logistic regressions to identify any effects on the process producing the outliers due to treatment or covariates.  相似文献

Over the past 20 years, several epidemiological studies have found an association between exposure to electromagnetic fields (EMFs) and health effects, including childhood leukemia and adult brain cancer. However, experts strongly disagree about whether this association is causal and, if so, how strong it is. In this article, we examine several alternatives to reduce EMFs from sources of the California power grid, including undergrounding distribution and transmission lines and reconfiguring or rephasing lines. The alternatives were evaluated in terms of the potential health risk reduction, cost, impacts on service reliability, property values, and many other consequences. Because of the uncertainty about an EMF-health link, the main effort was to determine the sensitivity of the decisions to the probability and seriousness of an EMF hazard. User-friendly computer models were developed to allow stakeholders to change the model assumptions and parameters to analyze the impacts of their own assumptions and estimates on the decision. The analysis clearly demonstrated that only four of the many concerns raised by the stakeholders could make a difference in the decision: health risks, costs, service reliability, and property values. Whether undergrounding, moderate alternatives for EMF reduction, or no change was the best decision depended on a few key factors, including the probability that EMF exposure is a hazard, the severity of this hazard, how the EMF reduction measures are financed, and the impacts on property values. While the analysis did not resolve the EMF issues, it showed that even in the most controversial settings, a little analysis goes a long way to clarifying the issues and to focus the debate.  相似文献

Altruism and social solidarity: Envisioning a field of specialization   总被引:1,自引:1,他引:0  
Conclusion This article has presented a vision of what a field of altruism and social solidarity could potentially involve. An additional perspective on the nature of this field and how it could contribute to the discipline and to society is provided by the science of psychology. In the last decade a fundamental new orientation has developed in this discipline, growing from the pioneering work of Martin E.P. Seligman. Generally identified as “positive psychology” it represents a shift from a focus on trying to understand and find solutions to mental illness and various pathologies of thought and behavior in a “disease model” to a focus on human strengths, virtues, and other positive characteristics. This shift in focus is regarded as making a direct contribution to understanding what is best in human emotions and traits and how society can support the psychological flourishing of individuals. This new perspective in turn provides increased awareness of how the problems studied in the disease model can more effectively be prevented (Seligman, 2003, 2005). The importance of this focus on the positive for sociology and a call to action is stated by Seligman (2003): The third pillar of positive psychology is the study of positive institutions and positive communities.  相似文献

Historical measures of income inequality in the United States must grapple with the challenge of data quality. We examine one such problem affecting the well-known estimates of income inequality produced by Piketty and Saez (2003) using the records of the Internal Revenue Service (IRS). Prior to 1943, incomes were self-reported. Combined with lax enforcement on the part of the IRS, self-reporting of incomes could provide a misleading portrait of the income distribution. To test the accuracy of IRS records, we compare them to independently tabulated state income tax returns between 1919 and 1945 from states with more comprehensive and rigorously enforced tax collection procedures. State income tax records show lower overall levels of income inequality than IRS records. However, we still find that top income concentrations declined across the period between 1929 and World War II. These findings attest to the sensitivity of distributional estimation to the reporting selectivity and economic quality of underlying tax data, suggesting that the existing IRS-derived series systematically overstates top-income concentration in the interwar period.
