How Much Is Leisure Worth? Direct Measurement with Contingent Valuation

This paper uses a contingent value survey in a Rocky Mountain city to measure the national income accounting value of leisure activities. Such direct measurement avoids shortcomings of the previously used labor value approach and individually values various types of leisure, e.g., napping and socializing. The results of the study indicate promise for this measurement approach but also raise some issues that require further research. Included are suggestions for overcoming problems discovered with this method and for future research.The authors wish to thank two anonymous referees of this journal who provided insightful comments and suggestions which improved the paper significantly.     

Effectiveness of couples treatment for spouse abuse

Despite its controversy, carefully conceptualized and delivered couples treatment appears to be at least as effective as traditional treatment for domestic violence, and preliminary data suggests that it does not place women at greater risk for injury. However, the body of research on which these conclusions rest is sparse. Only six experimental studies have been done, each using different eligibility criteria, outcome measures, and treatment approaches. Thus, further study of this modality is warranted. Marriage and family therapists have an important part to play in continuing to develop and test innovative ways of helping couples end violence and improve their relationships--an endeavor that promises to improve the quality of the partners' lives as well as those of their children.     

The new class of chief executive officer

This article summarizes the results of research into the ways in which environmental forces are changing the management task of chief executive officers of large corporations. The article comments on the changing business environment; on the time spent by managers on environmental forces; changes in the basic strategies of managers concerned with major social and political environmental forces; the characteristics which chief executive officers believe their successors must have to be effective managers; major ways in which the impact of environment on the CEO is changing the infra-structure and decision-making process; and, finally, a brief look at the future.     

Association between sexually explicit messages and sleep health among French sexual minority men

It has been demonstrated that sexual minority men (SMM) participate in sexting. While research has shown that engagement in the exchange of sexually explicit media is associated with poor health outcomes, no previous research has investigated its association with sleep health outcomes. This study sought to examine the association between sexually explicit media and sleep health among SMM, a population that suffers from poor sleep health. A popular geosocial networking application was used to recruit SMM individuals (N?=?580) in the Paris, France, metropolitan area. Multivariate analyses, adjusting for sociodemographics, were used to test the association between the frequency of sexually explicit messaging and three dimensions of sleep health: (1) sleep quality, (2) sleep duration, and (3) two aspects of sleep problems. In multivariate analyses, those who reported engaging in sexually explicit messaging more were more likely to report getting less than seven?hours of sleep (aRR = 1.24; 95% CI = 1.08, 1.43) compared with those who reported engaging in sexually explicit messaging less. No significant associations were found between sexting and sleep quality or reporting sleep problems. Sexually explicit messaging was associated with shorter sleep duration. Intervention targeted at individuals who sext could potentially improve sleep health outcomes.     

Waste identification diagrams

Value Stream Mapping (VSM) is a very popular tool in lean environments to represent production flows, mapping value stream of a product or family of products, and helps to identify some types of waste. Although very popular, this tool has some limitations as already described in many publications, especially in terms of restrictions in showing most types of waste as well as in its inability to represent various production routes. The purpose of this study is to introduce the waste identification diagram (WID), a new tool to represent production units with its different forms of waste, which overcomes some VSM limitations. The originality of WID comes from the use of its symbols’ dimensions to convey, in a visual and immediate way, relevant information about a production unit. In this paper, WID is applied on a production unit of a lift manufacturer, for testing its performance and comparing it to VSM. The main findings are that WID is in general more effective than VSM in terms of representation of complex production units and in terms of identification of more forms of waste. WID must however overcome some of its limitations such as the lack of information-flow representation and the links to suppliers and clients.

ON THE ROBUSTNESS OF MAJORITY RULE

We show that simple majority rule satisfies five standard and attractive axioms—the Pareto property, anonymity, neutrality, independence of irrelevant alternatives, and (generic) decisiveness—over a larger class of preference domains than (essentially) any other voting rule. Hence, in this sense, it is the most robust voting rule. This characterization of majority rule provides an alternative to that of May (1952). (JEL: D71)
