Measures of Spatial Segregation

The measurement of residential segregation patterns and trends has been limited by a reliance on segregation measures that do not appropriately take into account the spatial patterning of population distributions. In this paper we define a general approach to measuring spatial segregation among multiple population groups. This general approach allows researchers to specify any theoretically based definition of spatial proximity desired in computing segregation measures. Based on this general approach, we develop a general spatial exposure/isolation index (̃*), and a set of general multigroup spatial evenness/clustering indices: a spatial information theory index (̃), a spatial relative diversity index (̃), and a spatial dissimilarity index (̃). We review these and previously proposed spatial segregation indices against a set of eight desirable properties of spatial segregation indices. We conclude that the spatial exposure/isolation index ̃*—which can be interpreted as a measure of the average composition of individuals' local spatial environments—and the spatial information theory index ̃—which can be interpreted as a measure of the variation in the diversity of the local spatial environments of each individual—are the most conceptually and mathematically satisfactory of the proposed spatial indices.     

Costly and discrete communication: an experimental investigation

Language is an imperfect and coarse means of communicating information about a complex and nuanced world. We report on an experiment designed to capture this feature of communication. The messages available to the sender imperfectly describe the state of the world; however, the sender can improve communication, at a cost, by increasing the complexity or elaborateness of the message. Here the sender learns the state of the world, then sends a message to the receiver. The receiver observes the message and provides a best guess about the state. The incentives of the players are aligned in the sense that both sender and receiver are paid an amount which is increasing in the accuracy of the receiver’s guess. We find that the size of the language endogenously emerges as a function of the costs of communication. Specifically, we find that higher communication costs are associated with a smaller language. Although the equilibrium predictions do not perform well, this divergence occurs in a manner which is consistent with the experimental communication literature: overcommunication. We find that the sender’s payoffs, relative to equilibrium payoffs, are decreasing in the cost of communication. We also find that the receiver’s payoffs, relative to equilibrium payoffs, are increasing in the cost of communication. Finally, we find imperfections in coordination on the basis of the experimental labels.     

The BMI as a somatotypic measure of physique: A rejoinder to Jeremy E.C. Genovese

In 2008, Maddan, Walker and Miller promoted the use of the Body Mass Index (BMI) as a viable alternative to Sheldon's technique of somatotyping. Utilizing the BMI, Maddan Walker and Miller re-analyzed the original data from the Sheldon studies. This analysis indicated a statistically significant relationship between the two measures of somatotyping. Genovese wrote a response to this work suggesting the BMI is not a useful proxy for somatotyping individuals. We respond to Genovese's critique by providing a full explication of the Sheldon somatoype measure and an analysis of Sheldon's original data accounting for all of the different somatotypes identified. Analyses here indicate that the original somatotype measure was very subjective. Although not without flaws, the BMI provides an objective somatotype measure that is comparable, if not superior, to the measure promulgated by Sheldon.     

Gender-Specific Barriers to Self-Sufficiency among Former Supplemental Security Income Drug Addiction and Alcoholism Beneficiaries: Implications for Welfare-To-Work Programs and Services

This study examines barriers to economic self-sufficiency among a panel of 219 former Supplemental Security Income (SSI) drug addiction and alcoholism (DA&A) recipients following elimination of DA&A as an eligibility category for SSI disability benefits. Study participants were comprehensively surveyed at six measurement points following the policy change. Generalized estimating equations were used to examine full-sample and gender-specific barriers to economic self-sufficiency. Results indicate that access to transportation, age, and time are the strongest predictors of achieving self-sufficiency for both men and women leaving the welfare system. Gender-specific barriers are also identified. Future research needs to assess the generalizability of these results to other public assistance recipients.     

Subjective Well-Being and Life Satisfaction in the Kingdom of Tonga

This paper describes an initial attempt to assess the subjective well being of a sample of 227 Tongans via self-report. Using items adapted from the Subjective Well Being Inventory (SUBI; Nagpal and Sell, 1985; Sell and Nagpal, 1992), participants rated their level of overall life satisfaction along with their perceptions of well-beingin a number of other more specific life domains. Results indicated that mean ratings of global life satisfaction were generally positive. A factor analysis of the remaining domain-specific well-being items indicated that items loaded on to one of two factors dealing with overall positive or negative evaluations of these life areas. Importantly, these scale items stressed the importance of social and kin relations in contributing to overall well-being. In terms of demographic variables, mature respondents reported greater levels of overall life satisfaction and well-being as compared to youthful respondents. Implications and directions for future research are discussed.     

Child fatality review teams: a content analysis of social policy

Child fatality review teams (CFRTs) have existed since the 1970s; yet, a comprehensive understanding of their procedures, practices, and outcomes is lacking. This article addresses that gap in this study of CFRT state statutes. Findings indicate CFRT laws address nine areas of practice, from team composition, to purpose, to outcomes. Results also indicate that laws address prevention three times as often as investigation, but that both areas are related to state crime rates.     

Individualized Marriage and the Integration of Resources

In individualized marriages, spouses maintain independence in their relationship. In individualized marriages, do married couples manage their money in pooled accounts or do they keep separate accounts? We answer this question with the 2002 International Social Survey Programme (N = 18,587;31 country contexts) and examine how variation in the individualization of marriage is related to variation in resource integration within marriage. We make two contributions. First, we found that individualization matters. When couples understood and practiced individualized marriage, they were more likely to keep their money separate. The presence of individualized approaches to marriage and individualized alternatives to marriage within a country were also related to a higher likelihood of couples keeping money separate. Second, we found that integrating resources remained a constitutive part of marriage. Despite trends toward individualization and growing alternatives to marriage, most married couples continued to pool their money.     

Perceived Stigma and Depression among Black Adolescents in Outpatient Treatment

Despite the high prevalence of depression among children and adolescents, most that need mental health treatment do not seek care. This is especially true for ethnic minority adolescents. Prior research has shown that perceived stigma may act as a barrier to the initiation of and adherence to depression treatment, yet few studies have examined the relationship between stigma and depression among Black adolescents. This exploratory study examined the relationship between Black adolescents' depression severity and their current level of perceived stigma in an outpatient sample. Face-to-face interviews were conducted with a clinical sample of adolescents referred for mental health services at a community-based outpatient clinic (n =108), participating in a prospective pilot study on adolescents' patterns of mental health service use. The analyses revealed that greater depression severity was significantly associated with higher perceived stigma (p < .05), particularly among females. The results also suggest that Black adolescents appear to exhibit an appropriate level of self-assessment regarding their need for mental health services. These results are interpreted in relation to previous literature, and limitations and directions for future research are discussed.
