Association Study on Pathological Gambling and Polymorphisms of Dopamine D1, D2, D3, and D4 Receptor Genes in a Korean Population

Several studies have reported that some dopaminergic receptor polymorphisms are associated with pathological gambling (PG). Considering that there are major race and ethnic group difference in dopaminergic polymorphisms, the result of genetic association studies should be confirmed in more homogeneous population to avoid problems of population stratification. The present study aimed to investigate whether selected polymorphisms in the dopamine receptors genes (DRD1, DRD2, DRD3, and DRD4) are associated with PG in Korean population which is consisted of only Korean ancestry. Subjects were 104 men with a diagnosis of PG and 114 unrelated age-matched normal control men. Genotyping was performed for the DRD1 gene -48 A/G, DRD2 gene TaqI A, DRD3 gene Ser9Gly, and DRD4 gene exon III variable number tandem repeat polymorphisms. The method of multifactor dimensionality reduction (MDR) was used to analyze gene-gene interactions. There were no differences in the frequencies of any studied polymorphisms between patients with PG and normal controls. MDR analysis did not show a significant effect of the 4 dopamine receptor gene polymorphisms on susceptibility to PG (P > 0.05). The present study suggests that the analyzed polymorphisms of the dopamine receptor genes might not be associated with PG in a Korean population.     

Adolescent Marriage in Nepal: A Subregional Level Analysis

This study aims to identify the distribution of marriages among adolescents, aged 10 to 19 years, throughout Nepal. Data were obtained from the 2011 Nepal Demographic and Health Survey. Chi-square tests and logistic regression analyses were used to identify the main determinants of adolescent marriages (AMs). Of a total 11,967 weighted samples, 9.3% of adolescents (95% CI, 8–10%) were found to have been married; a significantly higher percentage of these were female. The variability of AMs varied among the regions of Nepal, with a higher percentage occurring in the Western Mountain, Mid-Western Hill, and Central Terai areas. AMs were also more likely to have occurred among poorer households. The findings show a substantial differences of AMs in different geographic areas and demographic levels in Nepal.     

“Allah will decide my life and death”: Religion and spirituality among populations at risk for HIV in Malaysia

ABSTRACT

We examined the influence of religion and spirituality on HIV risk contexts through in-depth interviews with men who have sex with men (n = 10) and female commercial sex workers (n = 10) in Malaysia. Using a grounded theory approach, five themes emerged from the interviews: (a) religion encourages caring for health, (b) health is influenced by a higher power, (c) prayer is a conduit to health assistance, (d) stigma is compounded by religion but it does not limit one’s spirituality, and (e) religion is not but should be incorporated into HIV campaigns. Incorporation of spirituality in service provision and addressing stigma is warranted.     

A baseline summary of framing research in public relations from 1990 to 2009

The present study examines the conceptualization of a frame, theoretical origins, analytical foci, and methods in framing research in public relations from 1990 to 2009. The most dominant type of a frame is construction of reality in communication found in 95% of 40 studies. Researchers compare public relations messages with news coverage, and also analyze public relations messages. Qualitative content analysis is more popular than quantitative content analysis or experiment.     

TESTS FOR DETECTING MORE NBU-NESS AT A SPECIFIC AGE

This paper proposes a class of non‐parametric test procedures for testing the null hypothesis that two distributions, F and G, are equal versus the alternative hypothesis that F is ‘more NBU (new better than used) at specified age t₀’ than G. Using Hoeffding's two‐sample U‐statistic theorem, it establishes the asymptotic normality of the test statistics and produces a class of asymptotically distribution‐free tests. Pitman asymptotic efficacies of the proposed tests are calculated with respect to the location and shape parameters. A numerical example is provided for illustrative purposes.     

Discrimination that Travels: How Ethnicity Affects Party Identification for Southeast Asian Immigrants*

Objectives. The critical importance of party identification as a determinant of vote choice is well documented. Given the increasing diversity of the population in the United States, it is critical that we understand the process of socialization into the political system for immigrant groups. It is especially important that we should be able to distinguish differences in socialization within a group. Methods. Using a framework developed by Cain, Kiewiet, and Uhlaner (1991) , we use newly available data to test their assertions about the development of party identification in Asian‐American immigrants. Results. Looking at a sample of foreign‐born Asian Americans, we find that critical differences can exist within groups. Conclusions. The differences within groups have an important effect on the development of party identification for those immigrants.     

The Dark Side of Information and Market Efficiency in E‐Markets*

Price dispersion reflects the differences in prices for identical products. While in physical markets such dispersion is prevalent due to high search costs, many researchers argue that search costs and price dispersion will be much lower in electronic markets (e‐markets). Empirical evidence does not support this contention, and researchers have studied search costs, market factors, and service‐quality factors to explain this dispersion. Previous research has largely assumed that more information is better. By ignoring the dark side of information, we argue that only a partial understanding of price dispersion is possible. In this article, information overload and equivocality are studied as two dark attributes of information that lead sellers to different pricing decisions in e‐markets. Hypotheses relating these attributes to price dispersion are supported through analysis of 161 product markets. This work opens up new avenues in the study of e‐markets and discusses the implications of these findings for research and practice on consumer and seller decisions.     

Men’s career development and marriage timing during a period of rising inequality

Based on data from 1979–1990 NLSY interviews, we investigate the implications of rising economic inequality for young men’s marriage timing. Our approach is to relate marriage formation to the ease or difficulty of the career-entry process and to show that large race/schooling differences in career development lead to substantial variations in marriage timing. We develop measures of current career “maturity” and of long-term labor-market position. Employing discrete-time event-history methods, we show that these variables have a substantial impact on marriage formation for both blacks and whites. Applying our regression results to models based on observed race/schooling patterns of career development, we then estimate cumulative proportions ever married in a difficult versus an easy career-entry process. We find major differences in the pace of marriage formation, depending on the difficulty of the career transition. We also find considerable differences in these marriage timing patterns across race/schooling groups corresponding to the large observed differences in the speed and difficulty of career transitions between and within these groups
