Family,marital, and occupational satisfaction for recovering pathological gamblers

This paper describes the efforts of a private gambling treatment program to conduct a retrospective study of pathological gamblers treated in a publicly supported residential program. The Johns Hopkins Center for Pathological Gambling treated approximately 100 pathological gamblers nationwide from 1979 to 1983 in its residential component. Twenty-six gamblers were assessed regarding their recovery status with specific focus on family, marital status and occupational satisfaction. It was hypothesized that the more satisfied patients would display lower frequencies of gambling and that gambling frequency was dependent upon the level of satisfaction. Thirty-one percent of these gamblers reported abstinence. Regression analyses indicated that the recovery of pathological gamblers as measured by frequency of gambling is significantly influenced by job satisfaction, and moderately influenced by marital status and family life satisfaction. Consequently, these factors should be addressed by mental health professionals in research and treatment of pathological gambling.     

The effects of prevailing wage laws: A comparison of individual workers’ wages earned on and off prevailing wage construction projects

I evaluate the effects of prevailing wage laws using a unique data set that shows the wages paid to workers on prevailing wage projects and the wages paid to the same workers during the same time period for work on projects not covered by prevailing wage regulations. The wage comparison shows that workers are generally paid more for work on prevailing wage projects than they are for work on nonprevailing wage projects. Thus, prevailing wage laws likely do increase the cost of public construction. In addition, to the extent that the quality of construction is improved, prevailing wage laws appear to be an inefficient mechanism by which to achieve additional quality, as the regulations often result in workers being paid more than they earn in the private market. This research was done originally for the Program Review and Investigations Committee of the Kentucky State Legislature. I thank the staff of the Program Review and Investigations Committee and the Legisla-tive Research Commission for assistance with data collection and Mark Berger for helpful comments. Due to confidentiality requirements, the data cannot be made available.     

ASYMPTOTIC LIKELIHOOD APPROXIMATIONS USING A PARTIAL LAPLACE APPROXIMATION

Elimination of a nuisance variable is often non‐trivial and may involve the evaluation of an intractable integral. One approach to evaluate these integrals is to use the Laplace approximation. This paper concentrates on a new approximation, called the partial Laplace approximation, that is useful when the integrand can be partitioned into two multiplicative disjoint functions. The technique is applied to the linear mixed model and shows that the approximate likelihood obtained can be partitioned to provide a conditional likelihood for the location parameters and a marginal likelihood for the scale parameters equivalent to restricted maximum likelihood (REML). Similarly, the partial Laplace approximation is applied to the t‐distribution to obtain an approximate REML for the scale parameter. A simulation study reveals that, in comparison to maximum likelihood, the scale parameter estimates of the t‐distribution obtained from the approximate REML show reduced bias.     

Managing the introduction of new technology

Most of the existing literature on the implications of new technology focuses on either its ‘impact’ or the social choices that lie behind strategies for its introduction into work organisations. The problems of managing the implementation of new technology have yet to be extensively examined despite this being one of the most critical aspects in the process of technological change. The findings from two case studies are presented which show how managers in the organisations concerned developed contrasting approaches to the problem of implementation in the context of opportunities and constraints presented by product markets and technological advance. Similarities between the two approaches are identified, in particular the role played by top management support in facilitating the acceptance of the new technology. The argument that management is able to develop a single unitary strategy towards the introduction of new technology is rejected in favour of a view of managerial actions as a series of flexible and changing sub-strategies associated with different stages in the process of change.     

Demographic Foundations of Political Empowerment in Multiminority Cities

As U.S. cities accommodate increasing ethnic and racial diversity, political choices may unify or divide their local populations. Those choices pull communities toward two different modes of pluralism: traditional “melting pot” assimilation or a complex mosaic of racial and ethnic assertiveness. Central to this issue is equity and empowerment, which may be accentuated by minority populations’ size, structure, and spatial concentration. We examine two potential modes of local empowerment: “dominance,” whereby each group is the majority of voters in single election districts (reinforcing separative tendencies), and “influence,” whereby a group gains “influential minority” status in several districts (reinforcing unifying tendencies).     

Digital Image Processing

Many of the tasks encountered in image processing can be considered as problems in statistical inference. In particular, they fit naturally into a subjectivist Bayesian framework. In this paper, we describe the Bayesian approach to image analysis. Numerical examples are not included but can be found among the references, in the previous Special Issue of this Journal and elsewhere. It is argued that the Bayesian approach, still in its infancy, has considerable potential for future development.
