Abstract

Using a lively classroom activity and a sense of humor is helpful in conveying a serious message about responsible sexual behavior to college students. The activity described takes only 1 hour, requires simple and easily obtainable equipment, and generates animated discussions. Students learn to feel more comfortable about using condoms after demonstrations of the strength and flexibility of these increasingly available items.  相似文献

The article analyses arguments for reform of public sector pension schemes by the UK Coalition government on the grounds that existing provision is ‘unfair’. Three dimensions of ‘fairness’ are discussed. That between public and private sector provision; between the costs to public sector employees and other taxpayers; and between members of public sector schemes. The article argues that there are serious weaknesses in the Coalition position on each of these dimensions of ‘fairness’. It suggests that these weaknesses are rooted in the discussion of public sector pensions in isolation from the overall pattern of occupational pension provision in the UK and that a more satisfactory analysis requires reference to principles of distributive justice.  相似文献

Little is known about the health status of adults living in continuing care retirement communities (CCRC). Using matched-case control, 458 adults from the Health and Retirement Study (HRS) or a CCRC-based sample were compared on total comorbidity, self-rated health, home health services use, and hospitalizations. At year 2, the CCRC sample reported more comorbidities (96%) but significantly better self-rated health (96% good/excellent) than the HRS sample (93% comorbidity, 73% good/excellent; p < .01). There were no significant differences in frequency of home health use or hospitalization. Living in a CCRC appears to be associated with higher self-ratings of health in this sample.  相似文献

Changes in mortality in the Soviet Union have attracted the attention of both scholars and the popular media. After a hiatus of more than ten years, the government of the Soviet Union has released data on mortality for the 1980s, which allow assessment of recent changes. The new life table for 1984–85 shows that mortality of Soviet females has improved at ages below 45 and deteriorated above that age since the last age-specific mortality data were published in the early 1970s, while mortality of males has improved at ages below 25 and deteriorated above that age. At the same time, the official mortality rates for persons aged 60 and over in 1958–59, 1968–71, and 1984–85 are implausibly low. Poor-quality data at the older ages, particularly in rural areas and the less developed regions of the country, contributed to these low mortality rates of the old. As data quality has improved with time, the reported mortality rates at old ages have increased. Adjustment of the official data for error, especially above age 60, shows that whereas the reported value of e0 for males fell by 1.5 years between 1958–59 and 1984–85, the actual value probably fell by no more than 0.5 years; the corresponding figures for females were a reported rise of one year, and an actual rise of at least two years. Examination of these Soviet data illustrates how important consideration of error in mortality statistics of the old can be in understanding mortality trends.  相似文献

Abstract

Portland State University collection development librarian Jill Emery talks with members of the Orbis Cascade Alliance demand driven acquisitions implementation team, EBL, and YBP Library Services about their participation in a pilot project to acquire e-books that are accessible to and jointly owned by the thirty-seven member libraries of the Orbis Cascade Alliance.  相似文献

In this paper, we argue that trust is an important aspect of social reality, one that realist social theory has paid little attention to but which clearly resonates with a realist social ontology. Furthermore, the emergence of an interest in trust in specific subject fields such as organization theory indicates the growing significance of issues of trust as market liberalism has developed. As such, the emergence of an interest in trust provides support for Archer's characterisation of late modernity in The Reflexive Imperative (2012) as a period of heterogeneity and greater incongruity. Commenting on this provides an opportunity to discuss the issue of habit in relation to trust and also the importance of the analysis of integration as a means to explain problems of trust. The commentary draws on examples from finance.  相似文献

An implicit assumption in distributing and coordinating work among independent organizations in a supply chain is that a focal organization can use financial or contractual mechanisms to enforce compliance among the other organizations in meeting desired performance objectives. Absent contractual agreement or financial gain, there is little incentive for independent organizations to coordinate their process improvement activities. In this study, we examine a health care supply chain in which the work is distributed among independent organizations. We use a detailed case study and an abductive reasoning approach to understand how and why the independent organizations choose to coordinate and collaborate in their work. Our study makes two contributions to the literature. First, we use well‐established lean principles to explain how independent organizations achieve superior performance despite highly uncertain and variable customer demand—a context considerably different from the origins of lean principles. Second, we forward relational coordination theory to explain why the organizations in this decentralized supply chain coordinate their work. Relational coordination includes the use of shared goals, shared knowledge, and mutual respect for one another's work as primary mechanisms to explain process improvement in the absence of any contractual incentives. Our study constitutes a first step in generating theory for work design and its improvement in decentralized supply chains.  相似文献

Consider the problem of several mathematical models competing to explain an empirical phenomenon. it is argued that fundamental model selection questions of model discrimination, model correctness and model adequacy can be answered by measuring the discrepancy of each model from an estimate of the unknown data generating process. Formally, the framework adopted is that of Linhart and Zucchini (1986), who considered a very general definition of discrepancy. In the present paper, it is demonstrated that requiring a discrepancy to possess several very reasonable properties is in fact equivalent to requiring it to be a metric on the relevant space of probability distributions.  相似文献
