Benefits and costs associated with mutual-help community-based recovery homes: The Oxford House model

We used data from a randomized controlled study of Oxford House (OH), a self-run, self-supporting recovery home, to conduct a cost-benefit analysis of the program. Following substance abuse treatment, individuals that were assigned to an OH condition (n = 68) were compared to individuals assigned to a usual care condition (n = 61). Economic cost measures were derived from length of stay at an Oxford House residence, and derived from self-reported measures of inpatient and outpatient treatment utilization. Economic benefit measures were derived from self-reported information on monthly income, days participating in illegal activities, binary responses of alcohol and drug use, and incarceration. Results suggest that OH compared quite favorably to usual care: the net benefit of an OH stay was estimated to be roughly $29,000 per person on average. Bootstrapped standard errors suggested that the net benefit was statistically significant. Costs were incrementally higher under OH, but the benefits in terms of reduced illegal activity, incarceration and substance use substantially outweighed the costs. The positive net benefit for Oxford House is primarily driven by a large difference in illegal activity between OH and usual care participants. Using sensitivity analyses, under more conservative assumptions we still arrived at a net benefit favorable to OH of $17,830 per person.     

Understanding increments in model performance metrics

The area under the receiver operating characteristic curve (AUC) is the most commonly reported measure of discrimination for prediction models with binary outcomes. However, recently it has been criticized for its inability to increase when important risk factors are added to a baseline model with good discrimination. This has led to the claim that the reliance on the AUC as a measure of discrimination may miss important improvements in clinical performance of risk prediction rules derived from a baseline model. In this paper we investigate this claim by relating the AUC to measures of clinical performance based on sensitivity and specificity under the assumption of multivariate normality. The behavior of the AUC is contrasted with that of discrimination slope. We show that unless rules with very good specificity are desired, the change in the AUC does an adequate job as a predictor of the change in measures of clinical performance. However, stronger or more numerous predictors are needed to achieve the same increment in the AUC for baseline models with good versus poor discrimination. When excellent specificity is desired, our results suggest that the discrimination slope might be a better measure of model improvement than AUC. The theoretical results are illustrated using a Framingham Heart Study example of a model for predicting the 10-year incidence of atrial fibrillation.     

Report on a case of sadism∗

While popular and psychoanalytic explanations of extramarital relations abound, no systematic sociological theory of such involvement has been presented to date. A partial theory of extramarital involvement is advanced in this paper. Based on the findings that the probability of involvement is related to socio‐economic status, the intensity of religious devoutness, residential background, premarital experience, the duration of marriage, level of marital satisfaction, and the degree of alienation, three propositions accounting for these relationships are set forth. On the basis of the theoretical propositions, the underlying dynamics of extramarital involvement are outlined and discussed.     

A survey of statistical methods on remote sensing in russian literature from 1976 to 1985

In this article we review the major areas of remote sensing in the Russian literature for the period 1976 to 1985 that use statistical methods to analyze the observed data. For each of the areas, the problems that have been studied and the statistical techniques that have been used are briefly described     

Tests of hypotheses based on ranks in the general linear model

A unified approach is developed for testing hypotheses in the general linear model based on the ranks of the residuals. It complements the nonparametric estimation procedures recently reported in the literature. The testing and estimation procedures together provide a robust alternative to least squares. The methods are similar in spirit to least squares so that results are simple to interpret. Hypotheses concerning a subset of specified parameters can be tested, while the remaining parameters are treated as nuisance parameters. Asymptotically, the test statistic is shown to have a chi-square distribution under the null hypothesis. This result is then extended to cover a sequence of contiguous alternatives from which the Pitman efficacy is derived. The general application of the test requires the consistent estimation of a functional of the underlying distribution and one such estimate is furnished.     

Parental Identity and Reflected‐Appraisals: Measurement and Gender Dynamics

A new theoretical model for parental identity, reflected‐appraisals, and behavior was proposed. Parental identity and behavior in married parents were then investigated as a function of partner's and perceived reflected‐appraisals, taking into account gender context effects. Sixty‐four married couples completed the Caregiving and Breadwinning Identity and Reflected‐Appraisal Inventory (CBIRAI), developed for this study to assess parental caregiving and breadwinning identity and reflected‐appraisals, as well as caregiving and breadwinning behavior measures. The model was confirmed for fathers and partially confirmed for mothers. Specifically, caregiving identity and behavior in fathers, and breadwinning identity in mothers were functions of perceived reflected‐appraisals. Limitations and implications are discussed.     

Government Capital,Intimate and Community Social Capital,and Food Security Status in Older Adults with Different Income Levels

Whether government‐based forms of food assistance such as the Supplemental Nutrition Assistance Program (SNAP), communal efforts including food pantries, aid from friends and family, or alternative means such as gardening are the appropriate means to reduce the prevalence of household food insecurity is a continuous source of policy contention. To inform this debate, we examine the relative importance of these forms of food assistance and acquisition to a sample of U.S. older adults from the 2010 Brazos Valley Health Assessment of central Texas households that have been stratified by income eligibility for SNAP, low‐income SNAP ineligibility, and above low income status. To identify how membership in these socioeconomic groups constrains household capacity to acquire sufficient food to maintain an adequate and healthy diet, we explore the varied associations of assets received from government; communal and intimate social networks; and alternative food sources such as gardening, hunting, and fishing with household food security across socioeconomic status, while examining the importance of place of residence on the use of capital assets. SNAP participation was the only specific capital asset associated with all levels of food insecurity for both SNAP‐eligible and ineligible low‐income groups, thus emphasizing the continued importance of food assistance among poverty‐level older adults.     

Heterosexual Masculinities,Anti‐homophobias,and Shifts in Hegemonic Masculinity: The Identity Practices of Black and White Heterosexual Men

In this study, I use in‐depth interview data with black and white heterosexual men to explore shifts in the role of homophobia in the social construction of heterosexual masculinities. A continuum is introduced to map a range of interactional practices through which these men enact heterosexual masculinities. Heterosexual men who, on one end of the continuum, construct their heterosexual masculinities through homophobic practices establish strong boundaries of social distance from gays. The other end documents heterosexual men's anti‐homophobias, moving from men who establish weak boundaries to those who blur them. These heterosexual men's anti‐homophobic stances trade on the prestige of being tolerant of gays, with black men's anti‐homophobias drawing on their experiences with racism.     

Are elderly drivers a road hazard?: Problem definition and political impact

Elderly drivers are increasing in number and some statistics show they are more likely to be involved in fatal accidents than all other age groups but those under 25. States have attempted to address the problem in various ways, but very few have required mandatory retesting at license renewal for those beyond a particular age. Why have so few states chosen to act? The key is how the issue is framed for the public and decision makers. Several phases of problem definition are explored to explain the political dynamics of the older driver issue: incidence, causality, severity, crisis labeling, problem population characteristics, and linkage of values to the issue and solutions. Based upon this analysis, it is not surprising that elder interest groups have been successful in containing policy initiatives designed to restrict elderly driving.     

Union militancy among public employees: A public choice hypothesis

Public employee union membership has grown from under 6 percent to over 20 percent of all union members since 1963. This growth has been ascribed to lagging wages, inelastic demands for public products, political clout, changed laws, and reduced professionalism and public spiritedness. These explanations agree that public employees now confront their employers in a newly militant and adversarial mode. We disagree. We model this growth in membership as a continuation of old public employment relations and forecast the soon diminution of militancy.
