A Comparison of Alternative Models for the Demand for Medical Care

We have tested alternative models of the demand for medical care using experimental data. The estimated response of demand to insurance plan is sensitive to the model used. We therefore use a split-sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error. Simpler models are inferior either because they are not robust to outliers (e.g., ANOVA, ANOCOVA), or because they are inconsistent when strong distributional assumptions are violated (e.g., a two-parameter Box-Cox transformation).     

WHERE THE MINIMUM WAGE BITES HARD: INTRODUCTION OF MINIMUM WAGES TO A LOW WAGE SECTOR

Between 1993 and April 1999 there was no minimum wage in the United Kingdom (except in agriculture). In this paper we study the effects of the introduction of a National Minimum Wage (NMW) in April 1999 on one heavily affected sector, the residential care homes industry. This sector contains a large number of low paid workers and as such can be viewed as being very vulnerable to minimum wage legislation. We look at the impact on both wages and employment. Our results suggest that the minimum wage raised the wages of a large number of care home workers, causing a very big wage compression of the lower end of the wage distribution, thereby strongly reducing wage inequality. There is some evidence of employment and hours reductions after the minimum wage introduction, though the estimated effects are not that sizable given how heavily the wage structure was affected.

Alcohol Screening and Brief Intervention as Standard Practice: Working with the American Indian/Native Alaskan Populations

Alcohol use and the resulting problems associated with high-risk drinking in the American Indian/Native Alaskan (AI/NA) population are well-documented, as alcohol misuse has taken an incredible toll on many AI/NA communities. Presently, both overall health issues and alcohol use occur disproportionately within this population. This article provides an updated overview of the impact of alcohol use in the United States and within AI/NA communities specifically. It also provides recommendations for an alcohol-related screening and brief intervention instrument that social workers can begin using in their practice and can be utilized within the AI/NA community.     

Executive functioning in Asian pathological gamblers

Two decades of neuropsychological research on predominantly Caucasian problem gamblers has unveiled significantly poorer performance on several domains of executive functioning (EF) relative to healthy controls. However, contradictory findings are widespread and evidence that pathological gamblers (PGs) are ‘impaired’ remains inconclusive. The study examined multiple facets of EF in 30 male, PGs seeking outpatient treatment in Singapore and 30 matched controls. CANTAB® tests of planning and organization/problem-solving, set-shifting, working memory and reflection impulsivity, were administered alongside the Barratt Impulsiveness Scale, Cognitive Failures Questionnaire and Dysexecutive Questionnaire. No significant group differences were found on any of the EF performance parameters, with performance falling in the healthy, unimpaired range for both groups. PGs did, however, report significantly greater impulsivity, everyday cognitive failures and symptoms of the dysexecutive syndrome. Exploratory analysis on a subgroup of PGs addicted to non-strategic gambling activities revealed poorer EF performance than among those addicted to strategic gambling activities. The findings suggest an absence of EF deficits despite higher trait impulsivity in Asian, predominantly strategic PGs. Hence, psychological interventions such as CBT and treatment approaches that emphasize the use of self-monitoring and informed decision-making to reduce impulsive behaviours should be suited to this population.     

College students' knowledge and health beliefs about AIDS: implications for education and prevention

A questionnaire designed to measure the application of the dimensions of the Health Belief Model (HBM) to AIDS prevention and to practicing safer sex was administered to 139 undergraduates aged 22 years and under. Students generally had good knowledge about the facts of AIDS, which was consistent with other studies. We found an important difference between students' beliefs about practicing safer sex to prevent AIDS depending on whether their level of knowledge was high or low. The HBM posits that all of its dimensions must be present in order for belief to be followed by action. However, students with low knowledge indicated that the perceived barriers to practicing safer sex were higher than did students with high knowledge about AIDS. These results suggest that special efforts need to be made to teach students with low knowledge more about AIDS and that the barriers to safer sex can and should be overcome. There were no differences between students known to be sexually active compared with those who may or may not have been sexually active. One explanation was a possibly high number of students in the group identified as "perhaps sexually active" who actually were sexually active. Similarly, there were no differences between college students who did or did not know someone with AIDS, but this may have been due to the small number of students who did know such a person. Students' preferences for the format and methodology of AIDS education also were presented. In general, the students preferred small-group discussions and formats such as movies or panel discussions where they could remain "anonymous."(ABSTRACT TRUNCATED AT 250 WORDS)     

Change and continuity among minority communities in Britain

We compare the Pakistani and Bangladeshi communities in Britain with other ethnic minorities to ask the questions ‘are Muslims different?’ and ‘is their behaviour changing over time?’. We look at the gender gap in education, age at marriage, marriage from the source country and female employment. In all these dimensions we find that Muslim communities are different but also that there is a convergence in behaviour. This is because those born in Britain generally differ markedly in behaviours from those born in the country of origin, but also because there is change within both the UK- and foreign-born communities.
