Problem Gambling Associated with Violent and Criminal Behaviour: A Danish Population-Based Survey and Register Study

This study compares the number of criminal charges among problem gamblers (N = 384) and non-problem gamblers including non-gamblers (N = 18,241) and examines whether problem gambling is more strongly associated with income-generating crimes like theft, fraud and forgery than other types of crimes such as violent crimes. A cohort study was carried out, based on data from the Danish Health and Morbidity Surveys in 2005 and 2010, which were linked at the individual level with data from The Danish National Criminal Register. Multiple logistic regression analyses were used to determine the association between problem gambling and charges for different categories of crime. We found that problem gamblers had significantly higher odds of being charged than non-problem gamblers (adjusted odds ratio 1.5; 95 % confidence interval 1.1–1.9). The odds ratio for economic crime charges was 2.6 (1.5–4.5), for violence charges 2.2 (1.1–4.5), and for drug charges 3.7 (1.7–8.0). For road traffic charges the odds ratio was 1.3 (1.0–1.8). Hence, there was a strong association between problem gambling and being charged except for road traffic charges; however the association was not stronger for economic charges than for violence and drug charges.     

Internet and the Political Public Sphere

The article addresses the main theory of the political public sphere generally, and the role of the Internet and Internet‐based media in the theory specifically. It first reviews briefly the initial social research on the Internet in the 1990s concerning political participation. After a presentation of Jürgen Habermas' theory of the contemporary public sphere, it proceeds to discuss the main problems concerning the Internet as a platform or infrastructure for public debate: segmentation and concentration. It argues that a general conclusion is that the public sphere differentiates and become more complex. A key task for future research, it argues, is to investigate the complex connections between Internet publics and mass media publics.     

On the foundation and early development of domestic and international new ventures

The founding and early development of Domestic New Ventures and International New Ventures is examined based upon a large scale survey of Danish manufacturing firms. The firms are classified into five different categories and compared with regard to their foundation and development within the first 3?years. The article contributes with a demonstration of differences between these categories of firms with regard to the number and mindset of founders, the growth of the firm, and the networks of firm.     

Psychosocial factors and safety behaviour as predictors of accidental work injuries in farming

Farming is one of the most hazardous occupations in terms of the incidence and seriousness of accidental injuries. Research with other occupational groups has drawn attention to the role of psychosocial factors and stress. Such research needs to be extended to agriculture. Since stress may be a problem faced by farmers, there is a particular need to investigate the associations between farm accidents and work stressors and stress reactions. Using multivariate logistic regression analyses, this study aimed to uncover the best psychosocial predictors of injury, while controlling for exposure-related confounders. From a randomly selected sample of 794 farms, 10% of all farms in Ringkoebing County, Denmark, 393 farmers completed completed weekly accident registration over 12 months. The study sample consisted of 310 farmers who also completed questionnaires on psychosocial factors. Results indicated that farm stressors (including perceived economic problems), stress symptoms, and safety behaviour were predictors of occupational farm accidents. Higher levels of stressors and stress symptoms and poor safety behaviour were all associated with an elevated risk of injury. In the case of stress symptoms, the relation with accidents occurred via an interaction with safety behaviour. The combination of high levels of stress symptoms and poor safety behaviour was associated with a particularly high accident risk.     

Strategy-proofness of continuous aggregation maps

 We consider continuous aggregation maps (e.g., social welfare functions). By assuming that the voters have preferences over social outcomes, we regard the social decision procedure as a noncooperative game, with the aggregation map as a game form. The map is called strategy-proof if it is a Nash equilibrium that the voters report their most preferred outcomes. We give sufficient topological conditions on the space of outcomes so that only dictatorial maps are strategy-proof. Received: 28 February 1994/Accepted: April 22, 1996     

TSP in spreadsheets—A fast and flexible tool

The traveling salesman problem (TSP) is well-known and many specially developed solution procedures have been constructed to solve particular variants of it. This paper considers several different variants of TSP. However, developing tailored solution procedures for each is impractical. These problems are non-deterministic polynomial-time hard (NP hard). Solving them using standard linear programming/mixed integer programming (LP/MIP) solvers has therefore only been regarded to be feasible for very small problems. A careful consideration of the problem formulation may facilitate efficient software utilization, and for real-world problems this can have a considerable impact. Problems that were previously regarded as large and unwieldy are now easily solvable using spreadsheets, thanks to the recent advancement in general optimization software.     

Veiled and Vulnerable: The Other Side of Grandiose Narcissism

This paper provides a consideration of a broadened scope of pathological narcissism, with particular attention towards the hidden and vulnerable aspects of this clinical phenomenon. The narcissism construct is briefly reviewed, along with contemporary issues in understanding the different presentations of narcissistic dysfunction. Selections from the theoretical literature are then explored in order to offer a nuanced conceptualization of the vulnerable side of pathological narcissism. Clinical implications of these perspectives are then discussed, along with clinical case material, to illustrate the presentation and treatment of narcissistic vulnerability.     

Cross-National Measurement Invariance of the Teacher and Classmate Support Scale

The cross-national measurement invariance of the teacher and classmate support scale was assessed in a study of 23202 Grade 8 and 10 students from Austria, Canada, England, Lithuania, Norway, Poland, and Slovenia, participating in the Health Behaviour in School-aged Children (HBSC) 2001/2002 study. A multi-group means and covariance analysis supported configural and metric invariance across countries, but not full scalar equivalence. The composite reliability was adequate and highly consistent across countries. In all seven countries, teacher support showed stronger associations with school satisfaction than did classmate support, with the results being highly consistent across countries. The results indicate that the teacher and classmate support scale may be used in cross-cultural studies that focus on relationships between teacher and classmate support and other constructs. However, the lack of scalar equivalence indicates that direct comparison of the levels support across countries might not be warranted.
