An Examination of the Relationship Between Gambling and Antisocial Behavior

Problem gambling is significantly more prevalent in forensic populations than in the general population. Although some previous work suggests that gambling and antisocial behavior are related, the extent and nature of this relationship is unclear. Both gambling and antisocial behavior are forms of risk-taking, and may therefore share common determinants. We investigated whether individual differences in personality traits associated with risk-taking, the Big Five personality traits, and antisocial tendencies predicted gambling and antisocial behavior among 180 male students recruited for a study of gambling (35.0% non-problem gamblers, 36.7% low-risk gamblers, 21.7% problem gamblers, and 6.7% pathological gamblers). All forms of gambling and antisocial behavior were significantly correlated. Personality traits associated with risk-acceptance explained a significant portion of the variance in problem gambling, general gambling involvement, and all forms of antisocial behavior. Antisocial tendencies (aggression and psychopathic tendencies) explained a significant portion of additional variance in severe antisocial behavior but not moderate or minor antisocial behavior. When controlling for personality traits associated with risk-acceptance, the relationship between gambling and antisocial behavior was greatly diminished. The results are consistent with the hypothesis that gambling and antisocial behavior are associated because they are, in part, different manifestations of similar personality traits.     

E-optimal designs for three treatments

E-optimality is studied for three treatments in an arbitrary n-way heterogeneity setting. In some cases maximal trace designs cannot be E-optimal. When there is more than one E-optimal design for a given setting, the best with respect to all reasonable criteria is determined.     

A new mixture model for capture heterogeneity

Summary.  We propose a mixture of binomial and beta–binomial distributions for estimating the size of closed populations. The new mixture model is applied to several real capture–recapture data sets and is shown to provide a convenient, objective framework for model selection. The new model is compared with three alternative models in a simulation study, and the results shed light on the general performance of models in this area. The new model provides a robust flexible analysis, which automatically deals with small capture probabilities.     

The weight of the rich: improving surveys using tax data

The Journal of Economic Inequality - Household surveys often fail to capture the top tail of income and wealth distributions, as evidenced by studies based on tax data. Yet to date there is no...     

The Identification of Behaviour Disorder within the Community

In the absence of a clinical definition of Behaviour Disorder, those termed ‘Behaviourally Disordered’ are often considered unsuitable for psychiatric servicing and many end up inappropriately contained by the correctional system. The working definitions of 213 South Australian health and welfare professionals from six client areas (child/adolescent, psychiatric, intellectually disabled, brain-damaged, correctional and general) were surveyed. Respondents generally saw Behaviour Disorder as a recognisable disorder, involving both aggressive, disruptive behaviour and deficits in social adaptation. Perceptions of its presentation varied across client groups and across professional roles. The results highlighted a need for specialised community servicing for this group.     

Three-stage designs for monitoring clinical trials

Optimal three-stage designs with equal sample sizes at each stage are presented and compared to fixed sample designs, fully sequential designs, designs restricted to use the fixed sample critical value at the final stage, and to modifications of other group sequential designs previously proposed in the literature. Typically, the greatest savings realized with interim analyses are obtained by the first interim look. More than 50% of the savings possible with a fully sequential design can be realized with a simple two-stage design. Three-stage designs can realize as much as 75% of the possible savings. Without much loss in efficiency, the designs can be modified so that the critical value at the final stage equals the usual fixed sample value while maintaining the overall level of significance, alleviating some potential confusion should a final stage be necessary. Some common group sequential designs, modified to allow early acceptance of the null hypothesis, are shown to be nearly optimal in some settings while performing poorly in others. An example is given to illustrate the use of several three-stage plans in the design of clinical trials.     

Strategic Planning for Support Services for Children with a Parent or Close Relative in Prison

It has long been recognized that children with a parent or close relative in prison are more likely to experience educational difficulties, emotional distress, family breakdown and a substantial reduction in family income (Boswell 2002; Smith et al. 2007; Morgan et al. 2013b; Morgan and Gill 2013). Consequently, children with a parent in prison are more likely to require support from statutory services, especially education and social care. However, statutory support for this group of children is sparse, and children of prisoners tend not to be identified as a priority group. The demand on local authorities to spend their limited budgets wisely means tough decisions have to be made. These decisions are not taken in a vacuum: they are taken in a context of local need, consumer representation, central and local politics; underpinned by the values and attitudes of individual members as well as by the ethos or culture of the local authority itself. In this article we apply Axford's typology (2009) of the different cultures which underpin local authority service provision to data from a research study carried out in 2011 in one local authority which explored support provision in schools for children of prisoners. We examine the contradictions and gaps within the local authority's attempts to synergize the different modules of service delivery into a coherent pattern of provision, and we explore how changes in strategic culture might lead to improvements being made in terms of service delivery to this group of ‘vulnerable’ children.
