Congregational Composition and Explanations for Racial Inequality Among Black Religious Affiliates

Prior research suggests that congregational characteristics are associated with the racial attitudes of Black churchgoers. This study examines the relationship between congregational diversity and beliefs about the Black/White socioeconomic gap among Black religious adherents. Drawing upon pooled data from the General Social Survey and the National Congregations Study, we fit binary logistic regression models to estimate the association between congregational diversity and the explanations of Black/White economic inequality among Black religious adherents. Findings from our study reveal that congregational diversity is one factor that accounts for intragroup differences in racial attitudes among Black religious affiliates. Relative to Blacks that attend religious services in overwhelmingly Black congregations, Blacks that attend religious services in congregations that are overwhelmingly White are significantly less likely to attribute Black/White socioeconomic gaps to a lack of educational opportunities. Our study demonstrates that congregational diversity is a source of intragroup variation in racial attitudes among Black religious affiliates, which may attenuate the ability of such congregations to bridge racial divisions.

Association between sarcopenia and erectile dysfunction in males with type II diabetes mellitus

Background: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED.

Methods: The study included 98 male patients with type II diabetes mellitus (DM) aged 18–80?years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5–10 points indicated severe ED, a score of 11–20 indicated moderate ED, and a score of 21–25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups.

Results: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59?±?11.46?years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p?Conclusions: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance.     

Kuznets’s Inverted U-Curve Hypothesis: The Rise,Demise, and Continued Relevance of a Socioeconomic Law

This paper provides a historical analysis of the changing significance of the most influential statement ever made on inequality and development—Simon Kuznets’s “inverted U-curve hypothesis.” The shifting interpretations and appropriations of the hypothesis over time—from its status as a speculative supposition in 1955, to its rise and fall as a reified socioeconomic law, to its contested standing in the social sciences today—demonstrate how Kuznets’s arguments, originally advanced under more limited conditions, became transformed into overarching theoretical, empirical, and political constructions. This history suggests that even empirically grounded and testable social science models are contingent on the broader social and political contexts in which they are produced and negotiated.     

Capabilities and Well-Being: Evidence Based on the Sen–Nussbaum Approach to Welfare

One of the most significant theoretical contributions to welfare analysis across a range of disciplines has been the development of the capabilities framework by Sen and others. Motivated by the claim that freedom should play a key role in social evaluation, the capabilities framework suggests that we consider what it is that people are free to do, as well as what they actually do. Using data from the British Household Panel Survey in conjunction with a list of substantial values posited by Martha Nussbaum, we contribute to the operationalisation and testing of this approach. Specifically, we suggest that commonly used secondary data sources do provide some information about the capabilities people have and that this can be incorporated into models of (subjective) well-being such as those used by a growing number of labour and health economists. We find evidence that a wide range of capabilities exhibit statistically significant relations to well-being that the relations are complex and slightly different for men and women, and conclude with suggestions for future developments.     

Pascal’s and Tabarrok’s Wagers

In a recent paper A. Tabarrok [Believe in Pascal’s Wager? Have I Got a Deal for You!, Theory and Decision 48, 123--128, 2000] argued that a believer who accepts Pascal’s Wager should in addition accept payment of any given fee in return for a given increase in the probability of reaching God. However the conclusion is obtained from manipulations of infinities which are not valid in an expected utility model. In this note, an alternative model is formulated in which Tabarrok’s conclusion can be obtained.     

The effectiveness of Luxembourg's minimum guaranteed income

Using micro‐data for the year 2007, this article analyzes the effectiveness of Luxembourg's minimum guaranteed income (revenu minimum garanti — RMG) social assistance programme. First, we examine the effectiveness of the RMG by comparing the proportion of eligible households based on the different criteria for the years 2007 and 1986, and find that, in 2007, 5.5 per cent of households were eligible versus 3.75 per cent in 1986. A relaxation of the RMG's eligibility criteria implies that more low‐income households should have access to the RMG. As a second measure of programme effectiveness, the article estimates the extent of non‐takeup behaviour among those eligible for the RMG in 2007. It is found that just over 65 per cent of all households potentially entitled to the RMG do not claim. Regression analysis of the potential determinants of non‐takeup behaviour confirms the hypotheses derived from theoretical models in the literature, i.e. that rational motivation, such as the expected net utility from claiming, and stigma, play a major role in explaining levels of non‐takeup.     

On operations research and value conflicts

The paper addresses the question of how operations research (OR) ought to handle decision problems that involve value conflicts. First, we note that early OR was considered essentially value free within the OR community, with a mechanistic systems perspective, although some voiced concern that an analyst should not detach herself from the consequences of her work. Then we propose a value conflict scale, which we use to assess the conflict levels in a small sample of OR applications. We then turn to value identification. In practise, organizational value statements include many kinds of values, and we discuss how values can be sorted out according to ethical categories, which helps in identifying consequentialistic decision criteria. The next question is how values can be enacted in a decision process. We review findings in neuroscience, which indicate that intra-personal decision-making takes place in a field of tension between deliberation and affect. The implication is that low level conflicts may leave decision-makers too cold for values to be enacted and therefore want infusion of emotion. On the other hand, emotions in high-level conflicts may run too high to give reason a chance. Emotions, therefore, need to be tempered and this can be achieved through at least two strategies: a focus on consequences rather than virtues and rules and discourse ethics. These are the subjects of the two last parts of the paper. We conclude by proposing five ethical rules for OR analysis of value conflicts. An analyst should not regard herself as being detached from the decision that are made, should be conscious that good decision-making requires temperate emotions that balance affect and deliberation, should promote focus on consequences, should promote the view that stakeholders have intrinsic value; they should not be treated instrumentally and should encourage fair processes to identify stakeholder values.
