A Perspective on Problem Gambling Treatment: Issues and Challenges

Researchers face several challenges in conducting gambling treatment research. These include the impact of monetary incentives to participate, difficulty in subject recruitment, treatment ambivalence, heterogeneity of gambling behaviors among treatment samples, the role of natural recovery, the impact of intractable financial pressures, and the specification of adequate process and outcome measures. Each challenge is defined and potential resolutions suggested.     

The psychological contract: A critical review

Literature on the psychological contract has blossomed progressively over the last ten years to the extent that it is now firmly located within the lexicon of the Human Resource Management (HRM) discipline. Yet as this review indicates, the theoretical assumptions that seem to pervade the psychological contract literature are not without major deficiencies, which in turn pose serious questions around the continued sustainability of the construct as currently constituted. This paper addresses some of the central problems presently confronting the theoretical side of the psychological contract literature. In seeking to advance knowledge and understanding, this review calls for an alternative approach to studying the psychological contract on the basis of a more critical and discursive literature analysis. From this, the authors unpick the construct of the psychological contract as portrayed in much of the extant literature and argue that, in its present form, it symbolizes an ideologically biased formula designed for a particular managerialist interpretation of contemporary work and employment.     

Further exploratory analysis of split-plot experiments to study certain stratified effects

Designed experiments are a key component in many companies' improvement strategies. Because completely randomized experiments are not always reasonable from a cost or physical perspective, split-plot experiments are prevalent. The recommended analysis accounts for the different sources of variation affecting whole-plot and split-plot error. However experiments on industrial processes must be run and, consequently analyzed quite differently from ones run in a controlled environment. Such experiments are typically subject to a wide array of uncontrolled, and barely understood, variation. In particular, it is important to examine the experimental results for additional, unanticipated sources of variation. In this paper, we consider how unanticipated, stratified effects may influence a split-plot experiment and discuss further exploratory analysis to indicate the presence of stratified effects. Examples of such experiments are provided, additional tests are suggested and discussed in light of their power, and recommendations given.     

Sexual offenders' perceptions of their early interpersonal relationships: an attachment perspective

The present study examined the perceptions of early interpersonal experiences of sexual offenders (child molesters and rapists) and two criminal comparison groups. A grounded theory approach was applied to a comprehensive list of responses provided by the participants to questions about their early interpersonal experiences. The raw data was collapsed into 14 basic categories by grouping together responses of similar meanings. The categories were responsiveness, consistency, acceptance, boundaries, emotional regulation, autonomy, self-evaluation, developmental trauma, sexual abuse and deviation, physical abuse, loss, conflict, safety, and positive mediating interactions. In the second part of the study, the four groups were compared using the categories and the differences noted. All four groups experienced significantly negative early interpersonal experiences.     

The dangers posed by saddle points, and other problems, when using central composite designs

This paper discusses two problems, which can occur when using central composite designs (CCDs), that are not generally covered in the literature but can lead to wrong decisions-and therefore incorrect models-if they are ignored. Most industrialbased experimental designs are sequential. This usually involves running as few initial tests as possible, while getting enough information as is needed to provide a reasonable approximation to reality (the screening stage). The CCD design strategy generally requires the running of a full or fractional factorial design (the cube or hypercube) with one or more additional centre points. The cube is augmented, if deemed necessary, by additional experiments known as star-points. The major problems highlighted here concern the decision to run the star points or not. If the difference between the average response at the centre of the design and the average of the cube results is significant, there is probably a need for one or more quadratic terms in the predictive model. If not, then a simpler model that includes only main effects and interactions is usually considered sufficient. This test for 'curvature' in a main effect will often fail if the design space contains or surrounds a saddle-point. Such a point may disguise the need for a quadratic term. This paper describes the occurrence of a real saddle-point from an industrial project and how this was overcome. The second problem occurs because the cube and star point portions of a CCD are sometimes run as orthogonal blocks. Indeed, theory would suggest that this is the correct procedure. However in the industrial context, where minimizing the total number of tests is at a premium, this can lead to designs with star points a long way from the cube. In such a situation, were the curvature test to be found non-significant, we could end with a model that predicted well within the cube portion of the design space but that would be unreliable in the balance of the total area of investigation. The paper discusses just such a design, one that disguised the real need for a quadratic term.     

Navigating human rights across the life course

Issues related to human rights have increasingly moved to the forefront of professional concern in recent years. Despite this, there has been minimal attention paid to exploring how changing human needs across the lifespan impact upon human rights. This paper takes a broad look at human rights issues that occur across the life course, and uses examples of life course transitions to illuminate issues related to moral rights and human rights. The examples include family formation, raising children, adolescent maturation in the context of youth offending and grandparents parenting their grandchildren. Each example explores the contestable rights and responsibilities of children, young people and adults and the ways in which these are negotiated within the context of the family.
