Individual Preferences and Job Characteristics: An Analysis of Cooperative Credit Banks

The aim of this paper is to analyse individual preferences in relation to different job characteristics. More specifically, this work focuses on the case of employees of cooperative credit banks (CCBs) in Campania and accounts for certain fundamental institutional features: CCBs are designed to pursue specific member interests rather than profit maximization, and most employees are both owners and consumers. The research is conducted by applying a conjoint analysis approach with stated preference data. Novel features of the analysis include the application of this approach to empirical research on worker incentives and the use of a mixed logit model.     

A measure of output gap for Italy through structural time series models

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.     

Consumer Phase Risk Assessment for Listeria monocytogenes in Deli Meats

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.     

Vulnerability and Comorbidity Factors of Female Problem Gambling

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.     

Contests for Professional Status: Community College Faculty in Sociology

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.     

The Relationship of Parental Alcoholism and Family Dysfunction to Stress Among College Students

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.
