Reviews of problem gambling (PG) literature increasingly recognize the ways in which different ethnic groups are affected by gambling behaviors, yet discourse, which considers sociocultural factors within PG, remains limited. Literature on this topic is influenced by large inconsistencies amongst research studies, overlapping terminology, and variability in the validity of research studies, making conclusions difficult to draw. Despite these discrepancies, this paper explores how sociocultural factors influence PG among diverse cultural groups and provides specific practical implications for treating PG disorders in culturally diverse populations. Notable factors that exacerbate PG behavior cross-culturally include substance abuse, low socioeconomic status, lack of social activities, and geographic location. Culturally sensitive treatment options such as Motivational Interviewing and Cognitive Behavioral Therapy have been identified as effective treatments for PG with culturally diverse populations. This paper extends current thought by providing practical treatment recommendations that consider the subtle nuances of diverse populations. It explains how treatment providers and behavioral addiction professionals can increase their understanding and skills when conceptualizing PG clients from a diverse background.  相似文献

We examine differences in the value of statistical life (VSL) across potential wage levels in panel data using quantile regressions with intercept heterogeneity. Latent heterogeneity is econometrically important and affects the estimated VSL. Our findings indicate that a reasonable average cost per expected life saved cut-off for health and safety regulations is 7 million to7 million to 8 million per life saved, but the VSL varies considerably across the labor force. Our results reconcile the previous discrepancies between hedonic VSL estimates and the values implied by theories linked to the coefficient of relative risk aversion. Because the VSL varies elastically with income, regulatory agencies should regularly update the VSL used in benefit assessments, increasing the VSL proportionally with changes in income over time.  相似文献

I have suggested that at a given birth order the probability of having a further pregnancy is greater when the last pregnancy had been spontaneously aborted than when it resulted in a birth.2 Léridon,3in the course of a valuable paper on foetal wastage, presents data which, according to him, impugn my suggestion. I would like to question his claim.  相似文献

A correlation-type statistic for assessing multivariate normality is described. Its estimated finite sample distribution is tabulated, and its performance against certain alternatives is compared with that of a competing Cramer-von Mises type statistic in a Monte Carlo power study. A set of quadrivariate data is examined as illustration of the procedure.  相似文献

Incomplete moments are used to characterize income inequality and provide the basis for interdistributional Lorenz curves. Four measures of interdistributional inequality are considered and seen to be related to an interdistributional welfare interpretation. Based upon these measures, there has been a significant secular decline in interdistributional inequality between blacks and whites over the past 30 years.  相似文献
