Items assessing financial motives were recently integrated with the Gambling Motives Questionnaire (GMQ), resulting in a revised measure that assesses coping, enhancement, social and financial motives for gambling (GMQ-F). The aim of this research was to test the proposed four-factor structure of the GMQ-F, determine if GMQ-F responses were invariant across sex, and test a structural model that specifies links between motives, gambling frequency and problem gambling severity. Telephone surveys were conducted with 932 adult gamblers from across Manitoba, Canada, who responded to items from the GMQ-F and reported their frequency of gambling and levels of problem gambling severity. Confirmatory factor analysis yielded strong support for the four-factor structure of GMQ-F scores, and invariance testing provided evidence of measurement invariance across sex. Finally, support was found for the hypothesized structural model in which each gambling motive predicted gambling frequency, which in turn predicted problem gambling severity. Coping motives also directly predicted problem gambling severity. These results provide strong evidence in support of the validity of GMQ-F responses, offer further support for the integration of financial motives with the GMQ, and delineate relationships between gambling motives, gambling frequency and gambling-related harm.  相似文献

The aim of this paper is to achieve a reliable estimate of the output gap for Italy through the development of several models within the class of the unobserved component time series models. These formulations imply the decomposition of output into a trend component (the 'potential output') and a cycle component (the 'output gap'). Both univariate and multivariate methods will be explored. In the former, only one measure of aggregate activity, such as GDP, is considered; in the latter, unemployment and industrial production are introduced. A comparison with alternative measures of output gap, mainly those published by international organisations, will conclude.  相似文献

Consumer Phase Risk Assessment for Listeria monocytogenes in Deli Meats   总被引:1,自引:0,他引:1  
The foodborne disease risk associated with the pathogen Listeria monocytogenes has been the subject of recent efforts in quantitative microbial risk assessment. Building upon one of these efforts undertaken jointly by the U.S. Food and Drug Administration and the U.S. Department of Agriculture (USDA), the purpose of this work was to expand on the consumer phase of the risk assessment to focus on handling practices in the home. One-dimensional Monte Carlo simulation was used to model variability in growth and cross-contamination of L. monocytogenes during food storage and preparation of deli meats. Simulations approximated that 0.3% of the servings were contaminated with >10(4) CFU/g of L. monocytogenes at the time of consumption. The estimated mean risk associated with the consumption of deli meats for the intermediate-age population was approximately 7 deaths per 10(11) servings. Food handling in homes increased the estimated mean mortality by 10(6)-fold. Of all the home food-handling practices modeled, inadequate storage, particularly refrigeration temperatures, provided the greatest contribution to increased risk. The impact of cross-contamination in the home was considerably less. Adherence to USDA Food Safety and Inspection Service recommendations for consumer handling of ready-to-eat foods substantially reduces the risk of listeriosis.  相似文献

This study helps to address a deficiency of gender-specific research into problem gambling. It focuses on the gambling behaviors, family and personal histories and comorbid psychological disorders of 365 female gamblers from across Ontario, Canada, who responded to a mail-in survey. Specifically, this study looks at rates of depression and anxiety, concurrent struggles with other behaviors (such as alcohol and drug use, disordered eating, overspending and criminal activity) and abuse history reported by female gamblers. The reported rates are considerably higher than for the general female population. The findings of this study agree with previous research. They suggest that prevention strategies and treatment practices for female problem gamblers should take into account women’s mental health, addiction and trauma history as contributing factors in the development of problematic gambling.  相似文献

Community colleges are playing an increasingly important and visible role in higher education in the United States. However, the additional attention to community colleges has not produced the same degree of recognition regarding the importance and needs of the faculty within those institutions, who make up about 27 percent of all faculty members nation-wide. This article examines factors influencing the professional status of community college faculty. We argue that understanding the position of community college faculty in higher education today depends upon understanding that professional status is a dynamic and contested terrain, rather than a series of static characteristics. Following Abbott’s (1998) analysis of the efforts of librarians to achieve professional status, we consider how the changing structure of higher education in the United States may impact community college faculty as professionals, both positively and negatively. As one example of community college faculty raising their issues within a discipline-wide professional organization, we examine the current state of community college faculty with the American Sociological Association (ASA). We consider potential status changes for community college faculty in sociology within the context of the broad threats to the professional status of faculty across the higher education landscape. Paradoxically, these threats might result in an opening for efforts by community college faculty to improve their professional status, perhaps in coalition with faculty in other sectors of higher education.  相似文献

Abstract

Parents with a history of serious mental illness are vulnerable in many ways and are therefore likely to be accessing services from a range of government and community agencies. The use of multiple services, sometimes with conflicting practice frameworks, can result in sub-optimal management of these families. This study surveyed 77 service providers from a range of government and non-government agencies targeting their views regarding parents with a serious mental illness (specified in this study as schizophrenia, bipolar disorder and psychotic depression). They were asked what they perceived were difficulties for this population, interventions required to meet the needs of this group and finally, barriers to effective service delivery. We found that service providers reported that current services were inadequate for these parents. Parent-based interventions were seen as being more beneficial than those targeting children. Lack of liaison between agencies and lack of coordinated service provision were seen as the greatest barrier to effective service delivery. The results highlight the need for policy planners and service providers to develop strategies to ensure effective coordination between services that work with this population.  相似文献

Abstract

The relationship between collegiate adult children of alcoholics (ACOAs) and adult children from dysfunctional families (ACDFs) was examined to determine whether ACOAs and ACDFs were at greater risk of stress than non-ACOAs and non-ACDFs. The participants were 549 students from a midwestern university. The data collection instruments were the Children of Alcoholics Screening Test, 6-Item Version (CAST-6); the Family Adaptability and Cohesion Evaluation Scales, Version II (FACES-II); and the Perceived Stress Scale (PSS). A substantial proportion of the sample was classified as ACOA, ACDF, or both, and there was considerable overlap between the two groups. Both ACOA and ACDF status were found to be significant predictors of stress, with ACDF status being a better predictor than ACOA status. Possible explanations for the results and implications for collegiate wellness programs are discussed.  相似文献
