Latent Variable Models for Mixed Discrete and Continuous Outcomes

We propose a latent variable model for mixed discrete and continuous outcomes. The model accommodates any mixture of outcomes from an exponential family and allows for arbitrary covariate effects, as well as direct modelling of covariates on the latent variable. An EM algorithm is proposed for parameter estimation and estimates of the latent variables are produced as a by-product of the analysis. A generalized likelihood ratio test can be used to test the significance of covariates affecting the latent outcomes. This method is applied to birth defects data, where the outcomes of interest are continuous measures of size and binary indicators of minor physical anomalies. Infants who were exposed in utero to anticonvulsant medications are compared with controls.     

Inequality in Life Spans and a New Perspective on Mortality Convergence Across Industrialized Countries

The second half of the twentieth century witnessed substantial convergence in life expectancy around the world. We examine differences in the age pattern of mortality in industrialized countries over time to show that inequality in adult life spans, which we measure with the standard deviation of life table ages at death above age 10 years, S₁₀, is increasingly responsible for the remaining divergence in mortality. We report striking differences in level and trend of S₁₀ across industrialized countries since 1960, which cannot be explained by aggregate socioeconomic inequality or differential external‐cause mortality. Rather, S₁₀ reflects both within‐ and between‐group inequalities in life spans and conveys new information about their combined magnitudes and trends. These findings suggest that the challenge for health policies in this century is to reduce inequality, not just lengthen life.     

The Social Context of Young Children's Peer Victimization

The goal of this study was to investigate differences in the social context of peer victimization for preschoolers and kindergarteners. Data were collected from 168 children. For preschoolers, neither social acceptance nor friendships were significantly related to peer victimization. Instead, playing with peers and exposure to aggressive peers were associated with higher rates of peer victimization. For kindergarteners, exposure to aggressive peers also contributed to the risk for peer victimization, but being liked by peers and having friends were inversely related to victimization, thereby providing a buffering effect. The developmental implications of these findings are discussed.     

Redistribution and assimilation of ethnic populations: The Los Angeles case

Redistribution relative to metropolitan growth of Negro, other non-white and Spanish name populations is examined in Los Angeles County from 1940 to 1960 for a comparable grid of subareas. The subareas are defined relative to their maturity at different time points in order to partially control for population redistribution effects of neighborhood life histories, the spread of older subareas, and the persistence of neighborhood patterns. Shifts in ethnic concentration are shown for both older and newer subareas. Concurrent changes in neighborhood social structures and ethnic populations are described. Findings are categorized under three themes: First, ethnic population increments and redistribution were generally restricted to expanding older subareas. Ethnic populations did not spatially expand at a rate equal to the spread of the metropolis or of older subareas. Second, segregation is greater in both older and newer neighborhoods for Negroes than for other ethnic populations. Negroes experienced the largest proportional increments in both older and newer subareas, as well as the greatest stability in subarea occupancy. Finally, the spatial separation of ethnic populations impedes assimilation in that unique patterns of neighborhood structure come to characterize different ethnic populations, and changes in ethnic composition are reflected in changes in neighborhood social structures.     

Value Creation and the Alliance Experiences of Dutch Companies

This paper examines the effect on the market valuation of large Dutch companies following the announcements of international strategic alliances during the period 1985–1992. The effects are distinguished by type of alliance and country of origin of the partnering firms. While international strategic alliances are generally found to have a positive effect on a company’s market value, strategically and culturally distant foreign partners generate a strong negative effect. The results underscore the importance of conducting a strategic, operational and cultural audit of the partnering companies and the envisaged partnership. The audit needs to be taken as a starting point in developing the essential co-operation skills to make the alliance work and should become integrated within a comprehensive performance scorecard.     

EMOTIONAL ABUSE AND CONTROLLING BEHAVIORS IN HETEROSEXUAL RELATIONSHIPS: THE ROLE OF EMPLOYMENT AND ALCOHOL USE FOR WOMEN AND THEIR PARTNERS

The purpose of this study is to examine the role of economic resources, status compatibility, and alcohol consumption on forms of nonphysical abuse, such as controlling and emotional abuse. Specifically, we focus on the connections between women's employment, the employment of their partners, alcohol use, and women's risk of abuse in intimate relationships. We hypothesize that women in intimate relationships with men will experience more emotional abuse to the extent that they are economically vulnerable. Moreover, abuse should increase if their employment status, in relation to that of their partner, challenges the man's marital power. Moreover, alcohol use by women and/or their partners is also predicted to be associated with emotional abuse. We find some support for assertions that socioeconomic deprivation, as well as challenges to men's masculinity, is associated with emotionally abusive male partners. However, the prevalence and amount of alcohol use by the male partner stands out as the most consistent predictor of emotional abuse in heterosexual relationships.     

BECAUSE IT'S FREE POKER! A QUALITATIVE ANALYSIS OF FREE TEXAS HOLD'EM POKER TOURNAMENTS

The game of poker has dramatically increased in popularity in America over the past decade, and includes a new trend in poker in which tournaments are played with no monetary wagering. These “free” poker tournaments are the primary focus of this project. Our interest in these free poker tournaments was twofold: first, we wished to identify what would motivate a person to play poker when there is no profit motive; second, we wanted to learn how the social dynamics of the game itself may or may not change when monetary risk is not present. Through covert participant observation of free poker tournaments at four different locations we were able to discover three main motivations among the players: sharpening skills for later cash games, sociability, and gaining the status of a “regular player.” We also discovered that the tenor and tempo of the game tended to vary not as a function of the location, but rather because of the social class of the players. We offer several hypotheses to guide future research endeavors in this area.     

Do religiosity and spirituality really matter for social,mental, and physical health?: A tale of two samples

ABSTRACT

Some prior research has found that religiosity and spirituality can be related to health. However, the relationships are inconsistent, measures of religiosity and spirituality are often problematic and conflated with the health outcomes they are supposed to predict, and very little research on this topic specifies which aspects of health supposedly benefit from religiosity and spirituality. Using two sets of survey data (Sample 1 N = 347; Sample 2 N = 404), we examined whether religiosity and spirituality had direct or indirect effects on physical, mental, and/or social health. We found that spirituality, when conceptualized as belief and experience of the supernatural, had no direct or indirect effect on physical, mental, or social health. Religiosity had a small but significant direct effect on social health in one sample but not the other. We consider our findings in relation to religious privileging in the United States and how proreligious biases can lead to health inequalities.     

College Students' Attitudes toward Shared Responsibility in Decisions about Abortion: Implications for Counseling

Abstract

College students' (112 males and 152 females) perceptions of the extent to which males should share in abortion decision making in seven situations of unplanned pregnancy were surveyed by questionnaire. Associations between gender, religious preference, level of religious activity, and students' attitudes toward extent of shared responsibility for abortion decision making were compared. Results indicate that many male students are more willing to assume decision-making responsibility than females, in some situations, are willing to allow.
