This article is derived from a study the authors conducted during 1978–1979 to determine the extent of shared services participation by a group of metropolitan hospitals, the problems that occurred, and the recommendations that appeared realistic. It appeared from a survey of the literature that most writers on shared services had merely introduced the concept and some of its possible applications. Little had been done to study the actual incorporation of shared services into the management structure of the organization. This study is an attempt to look closer at the real, long-term acceptance of the idea by hospital administrators and to provide a clearer picture of the way in which shared services are being used or misused. 相似文献

The present study sought to incorporate recent suggestions for reciprocity research into an experimental design which could use behavioral base rate change as a method for determining nonverbal reciprocity in nondistressed couples. This study examined reciprocity by surreptitiously manipulating the touching behavior of one spouse, and monitoring responses of the other spouse. Forty couples were randomly assigned to either an experimental or control group. Couples were videotaped engaging in an assigned task which permitted interaction. During the interaction, positive touches, smiles, and headnods were monitored. Following instruction to do so, selected spouses in the experimental group increased their rate of touches. Results indicated that, in response, naive spouses subsequently increased their rate of touches. The results of this experiment provide supportive evidence for the lawful nature of reciprocity. The implications of these findings, and suggestions for subsequent reciprocity research, are forwarded. 相似文献

Visual sociologists and anthropologists attempting to create representations of social communities and cultural groups inevitably do so within a context of competing cultural images manufactured by the popular mass media. Thus, in order for sociologists and anthropologists to use visual media effectively and make an instructive contribution to our knowledge of culture and society they must operate with the fullest possible awareness of popular culture and media practice. It has become the task of visual social scientists to acquire an intimate knowledge, not only of the subject matter they hope to illuminate, but of the media through which they intend to represent it, for more than ever, the visual media is not just a tool for the study of culture but an integral part of the culture we study. 相似文献

The Lasso has sparked interest in the use of penalization of the log‐likelihood for variable selection, as well as for shrinkage. We are particularly interested in the more‐variables‐than‐observations case of characteristic importance for modern data. The Bayesian interpretation of the Lasso as the maximum a posteriori estimate of the regression coefficients, which have been given independent, double exponential prior distributions, is adopted. Generalizing this prior provides a family of hyper‐Lasso penalty functions, which includes the quasi‐Cauchy distribution of Johnstone and Silverman as a special case. The properties of this approach, including the oracle property, are explored, and an EM algorithm for inference in regression problems is described. The posterior is multi‐modal, and we suggest a strategy of using a set of perfectly fitting random starting values to explore modes in different regions of the parameter space. Simulations show that our procedure provides significant improvements on a range of established procedures, and we provide an example from chemometrics. 相似文献

Enrollment of women in science, technology, engineering, and mathematics (STEM) majors is disproportionately small and declining. This study examines social coping to explain the gender gap. Women undergraduates reported using significantly more social coping than did men. Multiple regression analyses revealed that social coping was a stronger predictor of commitment to major for women than for men. Social coping negatively predicted intent to turn over, or withdraw from, their major for women, but not for men. Unexpectedly, social coping negatively predicted academic course grade for men but not for women. Results suggest that women benefit more from social coping than do men. Implications for counselors and policy are discussed. 相似文献

The AMBER alert system is likely affected by a number of psychological processes, yet remains understudied. The system assumes people will remember Alert information accurately and notify police, but psychological research on related phenomena (e.g., memory, willingness to help) indicates that people may not be able or willing to act in ways the promote the success of the system. In addition, the system is intended to deter child abductions, however, the system could prompt copycat crimes from perpetrators seeking publicity. The system could also cause a precipitation effect in which a perpetrator who sees the Alert could decide to murder the child immediately to avoid capture. Policy recommendations are made based on psychological research and theory, although more research is needed to develop the most effective system possible. 相似文献

The U.S. Environmental Protection Agency (EPA) recommends the use of the one-sided 95% upper confidence limit of the arithmetic mean based on either a normal or lognormal distribution for the contaminant (or exposure point) concentration term in the Superfund risk assessment process. When the data are not normal or lognormal this recommended approach may overestimate the exposure point concentration (EPC) and may lead to unecessary cleanup at a hazardous waste site. The EPA concentration term only seems to perform like alternative EPC methods when the data are well fit by a lognormal distribution. Several alternative methods for calculating the EPC are investigated and compared using soil data collected from three hazardous waste sites in Montana, Utah, and Colorado. For data sets that are well fit by a lognormal distribution, values for the Chebychev inequality or the EPA concentration term may be appropriate EPCs. For data sets where the soil concentration data are well fit by gamma distributions, Wong's method may be used for calculating EPCs. The studentized bootstrap-t and Hall's bootstrap-t transformation are recommended for EPC calculation when all distribution fits are poor. If a data set is well fit by a distribution, parametric bootstrap may provide a suitable EPC. 相似文献

The British abolitionist George Thompson was an unequalled public face of the Northern states in Britain during the American Civil War. Capitalising on his reputation from decades of anti-slavery activism stretching back to the 1830s, Thompson lectured convincingly to a variety of British audiences on the emancipationist potential of the war, encouraging them to lend their support to the Northern cause. Revealing his continuing intellectual debt and personal connections to the American abolitionists around William Lloyd Garrison, this article uses Thompson’s activism to emphasise the continuing importance of transatlantic Garrisonian ideology and networks in a period that historians have previously characterised as a ‘rupturing’ in the movement. 相似文献
