Two methods of estimating the intraclass correlation coefficient (p) for the one-way random effects model were compared in several simulation experiments using balanced and unbalanced designs. Estimates based on a Bayes approach and a maximum likelihood approach were compared on the basis of their biases (differences between estimates and true values of p) and mean square errors (mean square errors of estimates of p) in each of the simulation experiments. The Bayes approach used the median of a conditional posterior density as its estimator. 相似文献

A model of organizational performance measurement that compels attention to the proper balance among quality, cost, and access; takes into account patient perceptions; produces clear targets for continual quality improvement (CQI); yields easily understood graphical displays; and captures health care organizations in simultaneous operation across the functions of cost, quality, and access was designed for the 22 medical treatment facilities of the Strategic Air Command. Such a tool provides practitioners, payers, and patients a range of information--from systemwide, facility, clinical service, and practitioner-specific insights on current performance to resource forecasts and easily understood targets for CQI. This case study shows that integrated performance modeling may be useful in examining many health management and reform issues. 相似文献

Summary. An important problem in the management of water supplies is identifying the sources of sediment. The paper develops a Bayesian approach, utilizing an end member model, to estimate the proportion of various sources of sediments in samples taken from a dam. This approach not only allows for the incorporation of prior knowledge about the geochemical compositions of the sources (or end members) but also allows for correlation between spatially contiguous samples and the prediction of the sediment's composition at unsampled locations. Sediments that were sampled from the North Pine Dam in south-east Queensland, Australia, are analysed to illustrate the approach. 相似文献

Summary. We show that the family of tempered stable distributions has considerable potential for modelling cell generation time data. Several real examples illustrate how these distributions can improve on currently assumed models, including the gamma and inverse Gaussian distributions which arise as special cases. Our applications concentrate on the generation times of oligodendrocyte progenitor cells and the yeast Saccharomyces cerevisiae . Numerical inversion of the Laplace transform of the probability density function provides fast and accurate approximations to the tempered stable density, for which no closed form generally exists. We also show how the asymptotic population growth rate is easily calculated under a tempered stable model. 相似文献

The rationale for the growth of nonprofit management education in the United States has recently been charted by O'Neill (2005). Ten years previously, the United States and the United Kingdom were at similar levels of development. By 2006 the parallel lines had been broken. Why has nonprofit management education expanded in the United States while provision of graduate education for the voluntary sector in the United Kingdom has stood still? This article explores the factors that have prevented parallel growth in education provision. It argues that the university as an institution, both in terms of its nature and its power structures, is one of those factors. It presents the story of the closing of the world's first voluntary sector course at the London School of Economics and concludes with reflection on the likely future of voluntary sector management education provision in the United Kingdom. 相似文献

This article presents a comprehensive strategy framework for integrating mental health, child welfare, education, substance abuse, and juvenile justice system services. It proposes an infrastructure of information exchange, cross-agency client referrals, a networking protocol, interagency councils, and service integration models. This infrastructure facilitates integrated service delivery. 相似文献
