Children of problem gamblers 总被引:1,自引:1,他引:0
Dr. Durand F. Jacobs Ph.D. Albert R. Marston Ph.D. Robert D. Singer Ph.D. Keith Widaman Ph.D. Todd Little Ph.D. Jeannette Veizades M.A. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1989,5(4):261-268
An anonymous 37-item Health Survey was administered to 844 randomly selected ninth- to twelfth-grade students in four Southern California public high schools. Systematic information was gathered about their general health, quality of life, school and work adjustment, involvement with a range of potentially addictive substances and activities, and indications of psychosocial maladjustment, including difficulties with the law and suicide attempts. A series of self-ratings of students who characterized one or both of their parents as having a compulsive gambling problem (N=52) were contrasted with those of their classmates who reported no gambling problem among their parents (N=792). Findings have been grouped into three major areas: (a) comparative levels and reported effects of involvement with health-threatening behaviors (i.e., smoking, drinking, drug use, overeating, and gambling); (b) comparative incidence of psychosocial risk indicators (i.e., broken home, unhappy childhood and teenage years, legal action pending, overall quality of youth rated as poor); and (c) comparative incidence of dysphoria, school and work problems, and suicide attempts. Across each of these areas children of parents said to gamble excessively were found to be at consistently greater risk than their classmates who did not describe their parents as having a problem with compulsive gambling. These findings strongly suggest that without early and competent intervention, children of parents who gamble excessively: (a) will be seriously disadvantaged when attempting to solve their present adolescent and future adult problems of living; and (b) as a consequence are, themselves, high-risk candidates for developing one or another form of dysfunctional adjustment, including an addictive pattern of behavior. 相似文献

The Monte Carlo (MC) simulation approach is traditionally used in food safety risk assessment to study quantitative microbial risk assessment (QMRA) models. When experimental data are available, performing Bayesian inference is a good alternative approach that allows backward calculation in a stochastic QMRA model to update the experts’ knowledge about the microbial dynamics of a given food‐borne pathogen. In this article, we propose a complex example where Bayesian inference is applied to a high‐dimensional second‐order QMRA model. The case study is a farm‐to‐fork QMRA model considering genetic diversity of Bacillus cereus in a cooked, pasteurized, and chilled courgette purée. Experimental data are Bacillus cereus concentrations measured in packages of courgette purées stored at different time‐temperature profiles after pasteurization. To perform a Bayesian inference, we first built an augmented Bayesian network by linking a second‐order QMRA model to the available contamination data. We then ran a Markov chain Monte Carlo (MCMC) algorithm to update all the unknown concentrations and unknown quantities of the augmented model. About 25% of the prior beliefs are strongly updated, leading to a reduction in uncertainty. Some updates interestingly question the QMRA model. 相似文献

A popular choice when analyzing ordinal data is to consider the cumulative proportional odds model to relate the marginal probabilities of the ordinal outcome to a set of covariates. However, application of this model relies on the condition of identical cumulative odds ratios across the cut-offs of the ordinal outcome; the well-known proportional odds assumption. This paper focuses on the assessment of this assumption while accounting for repeated and missing data. In this respect, we develop a statistical method built on multiple imputation (MI) based on generalized estimating equations that allows to test the proportionality assumption under the missing at random setting. The performance of the proposed method is evaluated for two MI algorithms for incomplete longitudinal ordinal data. The impact of both MI methods is compared with respect to the type I error rate and the power for situations covering various numbers of categories of the ordinal outcome, sample sizes, rates of missingness, well-balanced and skewed data. The comparison of both MI methods with the complete-case analysis is also provided. We illustrate the use of the proposed methods on a quality of life data from a cancer clinical trial. 相似文献

There are a disproportionate number of professional women working through temporary agencies. We develop a theory wherein this gender skewness in temporary-agency employment results from the differences in perceptions of control at work between men and women working through large traditional organizations. Our theory suggests that if control is perceived to be less for women than for men in large organizations, then women will tend to populate other work arrangements, like temporary agencies, in order to enhance their control. Propositions are tested via a unique data set comparing the responses of employees from both a London temporary accountancy agency and a large London accountancy firm. Our results are consistent with a lack of control driving professional women from large firms to temporary agencies, and neither rely on preference differences nor familial obligations. 相似文献

ABSTRACTIn the field of organization studies, little consideration has thus far been devoted to the study of literature. The lacuna in the extant scholarship is unfortunate insofar as there is much to be gained for researchers interested in understanding organization to critically engage with literature. As an illustrative example of how literature can inform myriad pertinent discourses in organization studies, in this piece we study the question of empathy. That is, we describe just some of what may be gleaned about empathy from literature using anecdotes from a pedagogical exercise. Finally, we close this piece with a brief overview of the articles selected for this special issue. 相似文献

This article begins with a discussion of the vital need for collaboration between social work and law enforcement professionals, with particular emphasis on the need for comprehensive training programs combining criminal justice and social work knowledge. It then documents several historical recommendations for training police social workers that are relevant today, and suggests that social work education programs of the future include provisions for transmitting social work knowledge to police officers. Similarly, social workers planning to practice in criminal justice settings need to have training in the administration of justice. 相似文献
