Differences in Cognitive Distortions Between Pathological and Non-Pathological Gamblers with Preferences for Chance or Skill Games

Cognitive distortions have been thought to play an important role in the development and maintenance of pathological gambling. The present study investigated whether severity of gambling problems and gamblers’ preference for chance or skill games were related to two sub-factors of cognitive distortions as measured by the Gamblers Belief Questionnaire: Luck/Perseverance, which reflects an individual’s perception that chance is favorable to him/her, and Illusion of Control, which reflects an individual’s perception that his/her behavior influences chance occurrences. Participants (N = 166) were recruited from a race track (n = 79), off-course betting facilities (n = 50) and from an online treatment program for problem gamblers (n = 49). Gambling severity was measured by the South Oaks Gambling Screen, and 73 were classified as pathological gamblers whereas 93 were classified as non-pathological gamblers. The present study supports previous proposals that cognitive distortions are core processes related to gambling behavior as pathological gamblers reported more cognitive distortions than did non-pathological gamblers. A preference for skill games was also associated with greater Illusion of Control compared to a preference for chance games. For gamblers preferring skill games there were no differences in Luck/Perseverance or Illusion of Control between pathological and non-pathological gamblers.     

Acquired immunity: immunosenescence and physical activity

Several lines of evidence indicate that infectious diseases, cancer, and autoimmune disorders occur more frequently in elderly people, thus suggesting that altered function of immune organs and cells, such as thymus and T and B lymphocytes are of primary importance in the pathogenesis of these diseases. Furthermore, old subjects are less responsive to vaccine than younger because of immune changes. The most common changes accompanying the adaptive immune system include decrement of T and B cells proliferation, repertoire degeneracy, increase of the memory cell type, decreased numbers of naive cells, and shift from T helper₁ (Th1) to T helper₂ (Th2) response. Regular exercise in the elderly may improve the alterations in acquired immunity which follow the physiological process of aging, allowing a major resistance against external pathogens and a better quality of life.     

Differences in labour force participation by motherhood status among second-generation Turkish and majority women across Europe

Second-generation Turkish immigrants make up an increasingly important segment of European labour markets. These young adults are entering the prime working ages and forming families. However, we have only a limited understanding of the relationship between labour force participation and parenthood among second-generation Turkish women. Using unique data from the Integration of the European Second Generation survey (2007/08), we compared the labour force participation of second-generation Turkish women with their majority-group counterparts by motherhood status in four countries. We found evidence that motherhood gaps, with respect to labour force participation, were similar for majority and second-generation Turkish women in Germany and in Sweden; however, there may be larger gaps for second-generation mothers than for majority women in the Netherlands and France. Cross-national findings were consistent with the view that national normative and social policy contexts are relevant for the labour force participation of all women, regardless of migrant background.     

Adolescence and Adult Work in the Twenty‐First Century

The transition from school to work is a story that meshes the life histories of youth and the economic and social development of societies. Drawing on reports from diverse regions of the world, this article describes the range of adolescent experiences as they encompass the completion of school and the commencement of adult work. As the 21st century begins, major threats to the preparation of youth for adult work include deficiencies in schools, hazards of the informal work sector, a lack of clear connections between school and work, and the misuse or underutilization of technology. Yet this transition is also a story of optimism, as the significance of youth for economic and social development is increasingly appreciated at the national and international levels. Accordingly, this article considers the broad policy implications of the survey and then details the lines of action that address challenges to the preparation of youth for adult work. Although many regions of the world share common challenges, the integration of youth into the 21st century world of work will depend on how each country formulates a unique response that is sensitive to its demographic profile, social institutions, cultural heritage, and economic conditions.     

Attitudes toward gambling among adolescents

It is well documented that attitudes toward gambling are a good predictor of problem gambling during adolescence. However, so far, little is known about what factors are associated with adolescents' gambling attitudes. This study used cross-sectional data (N = 2055, response rate 70.4%) from a representative sample of 17-year-olds in Norway to investigate the relationship between demographic, personality, motivational and social variables and gambling attitudes. Overall, adolescents' attitudes toward gambling were slightly negative. A multivariate analysis revealed that more favourable attitudes toward gambling were most strongly associated with family/peer approval of gambling. In addition, significant associations were found for gender (males more favourable); Sensation Seeking (positive association); Agreeableness (negative association); and family/peer gambling history (positive association for lifetime gambling, negative association for problematic gambling). Although a variety of individual-level and social factors are associated with more favourable attitudes toward gambling, it appears that family and peer approval of gambling are most important.     

Description and pre-post evaluation of a telephone and Internet based treatment programme for pathological gambling in Norway: a pilot study

Although the effectiveness of treatments for pathological gamblers is gaining support, only 10% of pathological gamblers seek treatment. Providing treatment via the Internet may lower the thresholds for treatment seeking. A new telephone and Internet based treatment programme for pathological gamblers is presented in this article, along with a pre-post evaluation of the programme. The participants (N = 112) were problem gamblers who were either self-referred or referred by their general practitioner. Data from post-treatment and 3-month follow-up are evaluated. The results suggest that using Internet and telephone-assisted treatment interventions can significantly reduce symptoms of pathological gambling (measured by the South Oaks Gambling Screen – Revised). The intervention was also associated with improvement on cognitive distortions, measured by the Gamblers Belief Questionnaire, and general psychological distress and psychopathology as measured by the Symptom Checklist-90-Revised. Although Internet-based treatment programmes have been suggested to have advantages compared to traditional face-to-face therapy, research in this area is scarce. This pilot study contributes to the growing literature in this area, and provides tentative support for the effectiveness of Internet based treatment interventions for pathological gamblers.     

Rationality on the rise: Why relative risk aversion increases with stake size

How does risk tolerance vary with stake size? This important question cannot be adequately answered if framing effects, nonlinear probability weighting, and heterogeneity of preference types are neglected. We show that the observed increase in relative risk aversion over gains cannot be captured by the curvature of the value function. Rather, it is predominantly driven by a change in probability weighting of a majority group of individuals who weight probabilities of high gains more conservatively. Contrary to gains, no coherent change in relative risk aversion is observed for losses. These results not only challenge expected utility theory, but also prospect theory.     

Improving Ratio Estimators of Second Order Point Process Characteristics

Ripley's K function, the L function and the pair correlation function are important second order characteristics of spatial point processes. These functions are usually estimated by ratio estimators, where the numerators are Horvitz–Thompson edge corrected estimators and the denominators estimate the intensity or its square. It is possible to improve these estimators with respect to bias and estimation variance by means of adapted distance dependent intensity estimators. Further improvement is possible by means of refined estimators of the square of intensity. All this is shown by statistical analysis of simulated Poisson, cluster and hard core processes.     

Arab Television in Academic Scholarship

Over the past 10 years, there has been an exponential increase in satellite television in the Arab world, with programming ranging from music videos to news, from reality TV programs to Islamic talk shows. Concurrent with this development has been the growth of academic scholarship on understanding the relationship between Arab television and social and political transformations in the Middle East. This article provides an overview of Arab television growth, especially that of pan‐Arab satellite channels such as Al‐Jazeera, and of scholarship about it. Academic work that focuses on theories of media globalization and the public sphere, and that is in conversation with Western journalism and global media studies, is highlighted.     

Viewing the future through a warped lens: Why uncertainty generates hyperbolic discounting

A large body of experimental research has demonstrated that, on average, people violate the axioms of expected utility theory as well as of discounted utility theory. In particular, aggregate behavior is best characterized by probability distortions and hyperbolic discounting. But is it the same people who are prone to these behaviors? Based on an experiment with salient monetary incentives we demonstrate that there is a strong and significant relationship between greater departures from linear probability weighting and the degree of decreasing discount rates at the level of individual behavior. We argue that this relationship can be rationalized by the uncertainty inherent in any future event, linking discounting behavior directly to risk preferences. Consequently, decreasing discount rates may be generated by people’s proneness to probability distortions.
