Examining DSM-IV Criteria for Pathological Gambling: Psychometric Properties and Evidence from Cognitive Biases

We examined the DSM-IV criteria for pathological gambling as assessed with the DSM-IV-based Diagnostic Interview for Gambling Severity (DIGS; Winters, Specker, & Stinchfield, 2002). We first analyzed the psychometric properties of the DIGS, and then assessed the extent to which performance on two judgment and decision-making tasks, the Georgia Gambling Task (Goodie, 2003) and the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994), related to higher reports of gambling pathology. In a sample of frequent gamblers, we found strong psychometric support for the DSM-IV conception of pathological gambling as measured by the DIGS, predictive relationships between DIGS scores and all cognitive performance measures, and significant differences in performance measures between individuals with and without pathological gambling. Analyses using suggested revisions to the pathological gambling threshold (Stinchfield, 2003) revealed that individuals meeting four of the DSM-IV criteria aligned significantly more with pathological gamblers than with non-pathological gamblers, supporting the suggested change in the cutoff score from five to four symptoms. Discussion focuses on the validity of the DSM-IV criteria as assessed by the DIGS and the role of cognitive biases in pathological gambling.     

Families formed as a result of donor insemination: the views of semen donors

This paper reports the views and feelings of semen donors at two London donor insemination (Dl) programmes regarding the recipients of Dl and the families created by this method. In particular it reports on: the types of recipients that donors wish to assist; their understanding of the legal position of donors and Di fathers; their views on the'matching' of donors and Dl fathers; their perception of Dl offspring's need or desire for information about the donor; their views on whether parents should tell their offspring about their Dl conception and regarding the secrecy surrounding Dl in general; and what they believe the community thinks about Dl. Overall, the donors perceive Dl families as being normal, and are very supportive of the autonomy and privacy of these families, but they also have concerns about the needs of the offspring. The authors draw attention to the need to take into account the views of donors in forming assisted reproduction policies, and also the need for the interests of the child to be paramount, as they are in the case of adoption.     

Towards Common Ground and Trading Zones in Management Research and Practice

The purpose and nature of management scholarship is contested, evidenced by debates about the ‘academic–practitioner divide’ and attendant remedies for addressing it, including mode 2 and mode 3 research, engaged scholarship, evidence‐based management and design science. In this paper the authors argue that, without a culture of dialogical encounter, management scholarship will never be able to emerge from its adolescence, and management will not develop into the profession that it should and can become. The central proposition is that the highly fragmented landscape of management (practice and scholarship) lacks sufficient capability for dialogue among the plurality of actors situated across that landscape. Developing the dialogical capability ultimately required to break this fundamental impasse demands, first, a shared sense of purpose and responsibility (akin to the Hippocratic Oath in medicine) and, second, institutional entrepreneurship to establish more and better ‘trading zones’. Drawing on the philosophy of pragmatism, the authors further this endeavour by identifying and proposing key elements of a statement of shared purpose and responsibility. Finally, they explore the nature and characteristics of successful trading zones, highlighting particular examples that have already been created in management studies.     

Local deprivation and the labour market integration of new migrants to England

ABSTRACT

Using data on new migrants to England from the Quarterly Labour Force Survey, we show how a key component of migrant integration - labour market progress in terms of wages and unemployment rates – is broadly positive in the early years after arrival across a range of migrant groups and across gender. However, the precise level of labour market success achieved varies considerably across groups reflecting both the initial entry-level and labour market trajectories after migration. Migrants from Western Europe and the Old Commonwealth countries have unemployment rates (wages) which are generally lower (higher) than other groups, particularly non-white groups, while migrants from the Accession countries experience relatively low unemployment but also low wages. Groups which have better outcomes on entry also tend to experience higher rates of progress over time in England. However, the extent of multiple deprivation in the local authority where migrants reside interacts with years since migration to dampen wage trajectories for some groups and accounting for deprivation highlights the importance of internal migration for access to employment. The results emphasise structural explanations for patterns of labour market integration of new migrants to England.     

Factors associated with exercise participation in adults with arthritis

Most people with arthritis are not regularly active. Understanding what factors influence exercise is essential for designing programs to increase participation. The objective of this study was to examine the correlates of exercise in people with arthritis. Using a cross-sectional design, sociodemographic, health-related, and psychosocial variables were collected from community-dwelling individuals with arthritis (N = 141). Associations with exercise level were examined with bivariate statistics (ANOVAs, chi-squares) and logistic-regression analyses. Exercisers were less likely than nonexercisers and insufficiently active people to report that arthritis negatively affected their physical and social functioning, and they reported more positive affect and greater self-efficacy (p < .05). Exercisers also reported less pain than nonexercisers (p < .05). In multiple logistic-regression analyses, self-efficacy and physical limitations remained independent predictors of exercise. The results suggest the need to target exercise self-efficacy when designing exercise interventions. Results also suggest the need to tailor exercise programs to individuals' physical limitations.     

An alternative approach for analysis of performance of one-sided cusum charts with variable sampling intervals

An alternative approach for analyzing performance of one-sided Cusum charts with variable sampling intervals (VSI) is proposed. In this approach, a Markov chain with some dummy states is used. By this approach some dynamic performance measures of the VSI Cusum charts, such as the distribution of time to signal and the average time to signal against a change-point, can be determined. Some numerical results are shown, and from these results the dynamic performance of VSI Cusum charts is discussed.
