Race,Region, and Earnings: Blacks and Whites in the South

Abstract Using data from the 1980 Public-Use Micro Sample (PUMS) A-file, we examine the effect of region on black and white earnings within the Black Belt and the rest of the South. We find that Black Belt residence depresses earnings for both blacks and whites, more or less equally. There was no support for the hypothesis that there would be a greater penalty to being black in the Black Belt, compared to being black in the non-Black Belt South. It is the additive effects of race and region that lead to lower earnings for Black Belt blacks. We conclude that region is a useful theoretical concept which needs to be more adequately theorized and incorporated into sociological analyses.     

The impact of institutional changes on corporate governance mechanisms in transition economies

We examine how institutional changes affect corporate governance in transition economies. We develop a transition model that specifies three stages of the transition process including the early, intermediate, and late. We develop a framework for assessing the effectiveness of widely recognized corporate governance mechanisms (CGMs) in and across these stages. Our general proposition is that as transition economies move from early, to intermediate, to late stages, effective CGMs tend to be those that are based on state administrative control power, social networks and private orders, and market forces and formal institutions, respectively. Our study has contributions and implications regarding the transition economies and the impacts of institutions on corporate governance.     

Characteristics of Older Adult Problem Gamblers Calling a Gambling Helpline

Background Few investigations have characterized groups of older adults with gambling problems, and published reports are currently limited by small samples of older adult problem gamblers. Gambling helplines represent a widespread mechanism for assisting problem gamblers to move into treatment settings. Given data from older adult problem gamblers in treatment, we hypothesized that older as compared with younger adult problem gamblers calling a gambling helpline would be less likely to report gambling-related problems.Design and methods Logistic regression analyses were performed on data obtained from January 1, 2000 to December 31, 2001, inclusive, from callers with gambling problems (N = 1,084) contacting the Connecticut Council on Problem Gambling Helpline.Results Of the 1,018 phone calls used in the logistic regression analyses, 168 (16.5%) were from older adults and 850 (83.5%) from younger adults. Age-related differences were observed in demographic features, types and patterns of gambling reported as problematic, gambling-related problems and psychiatric symptoms, substance use problems, patterns of indebtedness, and family histories of addictive disorders. Older as compared with younger adult problem gamblers were more likely to report having lower incomes, longer durations of gambling, fewer types of problematic gambling, and problems with casino slot machine gambling and less likely to report gambling-related anxiety, family problems, illegal behaviors and arrests, drug problems, indebtedness to bookies or acquaintances, family histories of drug abuse, and problems with casino table gambling.Conclusions Older as compared with younger adult problem gamblers calling a gambling helpline differ on many clinically relevant features. The findings suggest the need for improved and unique prevention and treatment strategies for older adults with gambling problems.     

Development of an evidence-based conceptual framework for workplace assessment

One solution to the underutilization of workplace accommodations is to use teleconferencing technology to conduct remote assessments, effectively expanding the geographical area that experienced rehabilitation specialists can cover. However, such an effort requires a highly structured and comprehensive assessment protocol. This paper reports on the analysis of 53 existing assessments to develop a conceptual framework for assessment and the use of that framework to evaluate the applicability of 10 work-related assessment protocols for remote tele-assessment. While none of the 10 protocols were found to be sufficiently comprehensive for our purposes, the conceptual framework itself will serve as an important tool to structure a new comprehensive protocol that will be developed. Moreover, the framework can also be used by providers of workplace assessments to evaluate the suitability of any assessment protocol to meet the needs of any particular individual or workplace situation.     

On extending bock's model of logistic regression in the analysis of categorical data

A general class of multiple logistic regression models is reviewed and an extension is proposed which leads to restricted maximum likelihood estimates of model parameters. Examples of thegeneral model are given, with an emphasis placed on the interpretation of the parameters in each case.     

A New Approach to Importance Sampling in Taylor’s Stochastic Volatility Model

This article presents the general analysis of finite high-dimensional integrals using the Importance Sampling (IS) in aim to the parameter estimation of Taylor’s stochastic volatility (SV) model. After we proceed to make an alternative derivation for Sequential Importance Sampling (SIS) in previous literatures, we propose a new approach to select the optimal parameters of sampler, which is called as Universal Importance Sampling (UIS). UIS minimizes the Monte Carlo variance and numerically performs at least the same accurately as the SIS algorithm, but the computational efficiency get greatly improved. We apply both methods and investigate the SV model on the data, then make comparisons of the results.     

Trends in Evolutionary Explanations for Human Male Same-Sex Eroticism: A Commentary on Riegel (2011)

Objectives: Riegel (2011) argued there is a moral panic surrounding the issue of male transgenerational eros in the West. In response, he offered a variety of contrasting perspectives, one being that such eros has an evolutionary basis. The present article offers commentary. Methods: I supplement his hypothesis with a review of seven related evolutionary hypotheses and then compare/contrast all eight. Results: All these hypotheses constitute a work in progress, which Riegel adds to by properly restricting evidence (e.g., cross-cultural) to male homoerotic type (i.e., transgenerational). Conclusions: Riegel contributes to addressing the moral panic, and his evidence-type matching, which is part of a new trend in this area, promises to improve validity.
