Identifying the distribution of the incidence rate of a disease over a region is a prediction problem where area‐specific random effects are to be estimated. The authors consider the inclusion of such effects at different levels of a hierarchical health administrative structure. They develop inference procedures for this type of multi‐level model and show that the predicted rates are approximately weighted sums of the crude rates obtained by pooling data on each level of the hierarchy. Their techniques are illustrated using infant mortality data from British Columbia. 相似文献

The literature on organisational performance is riddled with measurement problems that cannot easily be solved. In contrast we argue that elite theory in terms of performance can be more easily measured by the win record of sports organisations. Accordingly, this article argues that certain organisational peak practices are key to understanding how peak performance is sustained. Through data collected from the top ten sports organisations in the world we introduce the embryonic theory of Peak Performing Organisations (PPO). Sustained PPO practices offer more robust outcomes than the genre of High Performing Organisations. 相似文献

More than two million Bosnian Muslims were ethnically cleansed in the Balkan region; of these, 200,000 were killed while the others were forced to flee their homes and become refugees. This article focuses on the influence of societal and cultural values coupled with wartime experiences on the transition of Bosnian refugee families to their new countries. Consideration is given to culturally competent theoretical frameworks and practice principles social workers can use to assist Bosnian Muslim children and families in their adaptation process within their resettlement communities. 相似文献

A series of computer-simulation models relating mortality level to fertility behavior and to rates of natural increase assuming that couples made use of a perfect means of birth control, that they wanted to be highly certain of having at least one son survive to the father’s 65th birthday, and that all women were biologically capable of having the same number of children were reported earlier. A model identical to one presented earlier but assuming women to be of variable fecundity is presented here; the results are quite similar. Also, the results of models assuming that parents want to be highly certain of at least two surviving children regardless of sex are compared with models assuming parental desire to be highly certain of at least one surviving son. At high levels of mortality the rates of natural increase are quite similar. When mortality is at intermediate to medium-low levels, the two-surviving-children model shows a lower rate of natural increase than the surviving-son model. At very low levels of mortality, such as now experienced by the most advanced nations, the two-surviving-children model manifests a higher rate of natural increase than the surviving-son model. 相似文献

It is shown that the class of generalized cyclic designs provides resolvable designs which are efficient for estimating factorial effects. A practical problem is discussed and useful designs for two-factors experiments are listed. 相似文献

The four structural elements of action identified in Talcott Parsons' The Structure of Social Action—means, ends, conditions, norms—can be directly assimilated to the four variables which generate the AGIL schema: instrumental, consummatory, external, internal. The former set primarily define the unit act; the latter are generalized to the action system level. 相似文献

Multiple studies have concluded that manual patient transfer and repositioning techniques are a significant cause of low back injuries. The objective of this study was to compare the low back stresses resulting from the use of two different mechanical patient transfer assist devices with the use of traditional manual transfer techniques. The mechanical transfer systems used were the Barton Patient Transfer System and a Sling-Suspension Lift similar to a "Hoyer Lift". The back compressive forces derived using the Michigan 3D Static Strength Model (Version 4.0) and electromyography (EMG) of the muscles of the low back were compared. This study found that the mechanical assist devices placed less stress on the low back and were more desirable to use than the traditional manual techniques. The Barton System was found to be, in general, less hazardous and more preferred than the Sling Suspension Lift. 相似文献

While many studies have explored the correlates and outcomes associated with pornography use, the measurement of such use has relied heavily on self-definitions of pornography from research participants, and little is known regarding how individuals define pornography for themselves. Using a diverse sample of 2,089 individuals sampled from the online MTurk Web site, participants were asked to rate whether they felt 20 different examples of sexual media were pornography. Differences by gender, religious attendance, marital status, and pornography use patterns were explored. Results suggested significant variation across the sample in how specific examples of sexual media were perceived. In addition, response profiles significantly differed by gender, religious attendance, marital status, and use of pornography. Implications for the measurement of pornography are discussed. 相似文献
