Does the “Marriage Benefit” Extend to Same-Sex Union?: Evidence From a Sample of Married Lesbian Couples in Massachusetts

This study investigated the relationship between wellbeing and marital quality in a married lesbian sample from Massachusetts. Two hundred twenty five (225) participants responded to this mailed survey study. Participants completed a demographic questionnaire, the Dyadic Adjustment Scale (DAS), and the World Health Organization Quality of Life-Brief Instrument (WHOQOL-Bref). DAS scores were a strong predictor of reported wellbeing in all quality of life domains including physical, psychological, and financial wellbeing. Results support the finding in the heterosexual marriage literature that healthy marriage is associated with distinct wellbeing benefits for lesbian couples. Implications of these findings are discussed.     

Operations research in the management of the airlines

This paper is intended to present an introduction to the use of operations research in the international airline industry, and to demonstrate the scope and significance of the airline OR activities. First, the special reasons for the viability and spread of airline OR are discussed. Then a functional framework for an airline is outlined, to be used in analyzing the problems of an airline and relating the OR work to it. Four major applications are described, corresponding to four major components of the framework. These applications are: schedule development, overbooking control, crew scheduling and engine management, respectively. In each case we describe the problem and its significance, indicate the types of solution techniques which have been developed, and assess the implemented solutions. The paper concludes with comments on the current state-of-the-art and the future of airline OR. A detailed bibliography is given.Both of the authors have been operations research directors in major airlines and more recently have focused their attention upon the industry as academic researchers. This background has provided us with an unusual opportunity to analyze the role of OR in the airlines, and our paper seeks to share with the reader some of the insights we have gained thereby.     

股东参与治理的私人收益和社会收益的实证研究

本文探讨了股东参与治理所带来的私人收益、特定股权结构的社会收益以及股权集中成本三者之间的关系。我们分析的结果表明,当股东与经理人员之间的利益冲突水平较高、其它治理机制的作用较弱时,股权集中(股东参与治理的积极性较高)可以创造大量的社会收益;反之,股权的集中与分散程度(股东参与治理的积极性较低)对社会收益的影响不明显。本文的研究结论为我国股东参与治理及股权结构改革提供了重要启示。     

How do social work novices and experts solve professional problems? A micro-analysis of epistemic activities and the use of evidence

Evidence-based practice in social work is an intensely debated topic, with many differing perspectives on how it should be done. However, we know surprisingly little about how social workers actually engage in professional problem-solving and about the knowledge base of those processes. To shed light on this topic of social work expertise, we present a novel model of scientific reasoning and argumentation and investigate how experts and novices differ in the reasoning processes they engage in as they are confronted with social work problems. Vignettes were used to capture reasoning processes, and the corresponding verbal data were then analysed. In this study, 26 probation officers and 22 social work students participated. The findings show that experts differ from novices with respect to both their knowledge bases and the epistemic activities in which they engage. Furthermore, a cluster analysis revealed three common problem-solving strategies: evidence-based solution seeking (15 experts and 15 novices), shared problem-solving (8 experts) and explanation seeking (1 expert and 7 novices). The results indicate the need to improve the practical problem-solving skills of students through situated teaching methods.     

Constructing Well-Being and Poverty Dimensions on Political Grounds

The paper addresses the problem of justifying ethically sound dimensions of poverty or well-being for use in a multidimensional framework. We combine Sen’s capability approach and Rawls’ method of political constructivism and argue that the constitution and its interpretative practice can serve as an ethically suitable informational basis for selecting dimensions, under certain conditions. We illustrate our Constitutional Approach by deriving a set of well-being dimensions from an analysis of the Italian Constitution. We argue that this method is both an improvement on those used in the existing literature from the ethical point of view, and has a strong potential for providing the ethical basis of a conception of well-being for the public affairs of a pluralist society. In the final part, we elaborate on the implications for measuring well-being based on data, by ranking Italian regions in terms of well-being, and pointing out the differences in results produced by different methods.
