Self-Directed Gambling Changes: Trajectory of Problem Gambling Severity in Absence of Treatment

Most problem gamblers do not seek formal treatment, recovering on their own through cognitive re-appraisal or self-help strategies. Although barriers to treatment have been extensively studied, there is a paucity of research on self-directed changes in problem gambling and very few studies have examined these changes prospectively. The aim of this study was to examine the trajectory of gambling severity and behavior change over an 18-month period, among a sample of non-treatment seeking/attending problem gamblers recruited from the community (N?=?204) interested in quitting or reducing gambling. Separate mixed effects models revealed that in absence of formal treatment, significant reductions in gambling severity, frequency, and amount gambled could be observed over the course of a 6 to 9-month period and that changes experienced within the first 12 months were maintained for an extended 6 months. Problem gambling severity at baseline was significantly associated with changes in severity over time, such that participants with more severe gambling problems demonstrated greater reductions in their gambling severity over time. A total of 11.1% of participants gambled within a low-risk threshold at 18 months, although 28.7% of the sample reported consecutive gambling severity scores below problem levels for the duration of 1 year or longer. The findings suggest that among problem gamblers motivated to quit or reduce their gambling, significant self-directed changes in gambling severity can occur over a relatively short time. Additional prospective studies are needed to document the role of specific self-help tools or thought processes in exacting gambling changes.     

The Ranking of the Regions With Regard to Their Sports Facilities to Improve Their Planning in Sport: The Case of Spain

Sports facility planning by the public authorities should be considered to be one of the main policies to have an indirect influence on the aim of ensuring a healthy population, as well as reducing its physical inactivity. Our research aims to study and compare the state of sports infrastructures in the regions of Spain, using a synthetic indicators. Our results should serve not only to detect the vast imparity between different regions, which has come about because of varying investment and management with regard to sports infrastructures, but also to redirect building planning and sports management policies onto the right path, and also give food for thought.     

The Decent Work Questionnaire: Development and validation in two samples of knowledge workers

This research develops a Decent Work Questionnaire (DWQ) to measure workers’ perceptions of decent work. Current measurements of decent work are almost completely lacking at the individual worker level of analysis, and this study contributes to filling the gap. The authors designed their DWQ based on the substantive elements used by the ILO in its Decent Work Agenda, with the final 31‐item version of the DWQ yielding seven factors related to decent work. Showing good reliability coefficient values and good convergent and discriminant validity, this DWQ could open up new avenues for empirical studies on the concept of decent work.     

Production planning and control for remanufacturing: literature review and analysis

This article reviews the literature on production planning and control (PPC) for remanufacturing. The objectives are threefold: to determine whether the gaps identified by Guide (Guide Jr, V.D.R., 2000. Production planning and control for remanufacturing: industry practice and research needs. Journal of Operations Management, 18, 467–483) on the subject with respect to the main complicating characteristics of remanufacturing have been fulfilled; to classify the literature based on an appropriate structure to obtain a better understanding of the subject identifying sources of future research and to provide a useful source for scholars and practitioners. Seventy-six papers were examined and classified. It was found that none of the studies deals simultaneously with all of the complicating characteristics, and that more practical research is needed. In addition it was found that we lack studies regarding forecasting and aggregate planning considering disassembly of returned products, material matching restrictions or stochastic routings, master production scheduling considering material matching restrictions or stochastic routings, ordering system and capacity planning considering material matching restrictions and inventory control and management considering stochastic routings.     

Unions,Firing Costs,and Unemployment

Abstract. We study the effects of firing costs in unionized economies with heterogeneous workers. We consider an overlapping generations model where workers participate in the labour market both when young and when old. All workers belong to the same union that sets wages unilaterally. We find that at given wages firing costs increase youth unemployment and decrease old‐age unemployment. However, once the wage response is considered, firing costs increase both youth and old‐age unemployment. Indeed, knowing that when firing costs are higher firms refrain from firing, the union increases the wage of old workers, and, therefore, old‐age unemployment increases.     

Production planning and control for remanufacturing: exploring characteristics and difficulties with case studies

Production planning and control for remanufacturing is a major managerial challenge in the operations management. Researches demonstrate the need for decision-making methods in this context, which has generated theoretical and quantitative studies. However, this area still lacks empirical studies dealing with the practical, day-to-day difficulties of remanufacturers. The purpose of this paper is to link the literature and practice in a systematic in such a way that it is possible to show the similarities and differences between theoretically listed needs and real cases, thereby extending the results of previous research. For this purpose, four case studies are considered. The cases involve original equipment manufacturers (OEM) of automotive parts that have remanufacturing operations. The results indicate that these companies have difficulties that have not been addressed to date in the literature related to the uncertainties inherent in remanufacturing. In addition, we find that these companies use simplified decision-making approaches.     

The Impact of Body Dissatisfaction on Distressing Sexual Difficulties Among Men and Women: the Mediator Role of Cognitive Distraction

Research has demonstrated a negative impact of cognitive distraction on sexual activity, and body dissatisfaction has been associated with less satisfying and fewer sexual activities. In the current study we examined the extent to which cognitive distraction, based on body appearance and sexual performance, mediated the impact of body dissatisfaction on sexual difficulties among women and men. A sample of 493 women (M_age = 30.61) and 595 men (M_age = 37.90) completed an online survey. Women reported significantly higher levels of distressing sexual difficulties, significantly more body dissatisfaction, and greater cognitive distraction based on appearance than men. In contrast, men reported higher cognitive distraction based on performance than women. A path analysis model indicated that, for men, only cognitive distraction based on performance mediated the effects of body dissatisfaction on distressing sexual difficulties, and the mediation was only partial as body dissatisfaction had a significant direct effect on distressing sexual difficulties. In contrast, among women, both appearance-based cognitive distraction and performance-based cognitive distraction fully mediated the effects of body dissatisfaction on distressing sexual difficulties.     

Should I stay or should I go? Educational choices and earnings: An empirical study for Portugal

We analyse educational choices and earnings of individuals at two different levels in the Portuguese educational system. At each exit we consider two decisions: the decision to continue studying and the employment decision. We find empirical support for the existence of selectivity bias as the errors of the earnings functions are in general correlated with the disturbances of the decision functions. The obtained rates of return to education vary between 2.4 and 9.4 percent, depending on whether or not selectivity and quantity effects are excluded from the computations. Note that selectivity represents three quarters of this difference. Received: 5 March 2001/Accepted: 10 October 2001 I am grateful for the comments of the editor and two anonymous referees.

Estimation of cost allocation coefficients at the farm level using an entropy approach

This paper aims to estimate the farm cost allocation coefficients from whole-farm input costs. An entropy approach was developed under a Tobit formulation and was applied to a sample of farms from the 2004 Farm Accountancy Data Network data base for Alentejo region, Southern Portugal. A Generalized Maximum Entropy model and Cross Generalized Entropy model were developed to the sample conditions and were tested. Model results were assessed in terms of their precision and estimation power and were compared with the observed data. The entropy approach showed to be a flexible and valid tool to estimate incomplete information, namely regarding farm costs.
