Empirical evidence on the union free-rider problem: Do right-to-work laws matter?

This study provides detailed statistics by state, industry, occupation, and worker characteristics on private sector wage and salary workers covered by union collective bargaining agreements but who are not union members. A distinction is made between those workers who value the benefits of coverage more than the cost of membership, the true free riders, and those who do not, the induced riders. A probit union membership equation is estimated on a sample which excludes the covered nonmembers. Predicted probabilities are then calculated from the estimated model, yielding a quantifiable measure of the true free-rider problem. The author gratefully thanks Barry T. Hirsch, David A. Macpherson, and an anonymous referee for their constructive comments and insightful ideas. Any errors remain the sole responsibility of the author.     

Dividing to keep muscle together: the role of satellite cells in aging skeletal muscle

The factors responsible for the atrophy of skeletal muscle with aging remain to be elucidated. Recent evidence points toward an important role for a population of cells located on the surface of skeletal muscle fibers, known as satellite cells, in maintaining the integrity of skeletal myocytes throughout the life span. This Perspective examines the role that these cells are thought to play in aging muscle atrophy, and highlights a recent study by Brack and colleagues that attempts to understand the role of satellite cells in maintaining the ratio of myonuclear number to cytoplasmic volume within myocytes as we age.     

A Case of Mistaken Identity? A Comparison of Professional and Amateur Problem Gamblers

Professional gamblers are more likely than amateur gamblers to meet criteria for problem gambling but minimal research has examined their gambling behavior and its consequences. This study compared gambling behavior, problem gambling symptoms, related harms, recognition, and help-seeking among problem semi/professional gamblers (PPGs/PSPGs) and problem amateur gamblers (PAGs). Surveys completed by 57 self-identified professional gamblers, 311 semi-professional gamblers and 4226 amateur gamblers were analysed. PPGs/PSPGs were significantly more likely than PAGs to be male, younger, never married, speak a language other than English at home, and have higher psychological distress, compared to PAGs. PPGs/PSPGs were more likely to gamble more frequently on many skills-based forms, but most also participated in several chance-based forms. PPGs’/PSPGs’ most common problematic gambling form was electronic gaming machines and they were more likely to have problems with sports betting than PAGs. Most PPGs/PSPGs reported coming out behind on all gambling forms over the previous year. PPGs/PSPGs were more likely than PAGs to report chasing losses and numerous detrimental financial gambling consequences. This group’s self-identification as PPGs/PSPGs is clearly inaccurate and perhaps a means to avoid stigma, elevate status and support problem denial. PPGs/PSPGs may represent an extreme example of gamblers with erroneous cognitions and beliefs who lack the required discipline and skill to be successful professional gamblers. The findings identify a group of problem gamblers who may benefit from interventions to dispel their mistaken self-identity, and emphasize the need for more rigorous confirmation of professional gambler status in future research.     

Children’s Scales of Pleasure and Arousal

This article introduces the Children’s Scales of Pleasure and Arousal as instruments to enable children to provide judgments of emotions they witness or experience along the major dimensions of affect. In two studies (Study 1: N = 160, 3–11 years and adults; Study 2: N = 280, 3–5 years and adults), participants used the scales to indicate the levels of pleasure or arousal they perceived in stylized drawings of facial expressions, in photographs of facial expressions, or in emotion labels. All age groups used the Pleasure Scale reliably and accurately with all three types of stimuli. All used the Arousal Scale with stylized faces and with facial expressions, but only 5-year-olds did so for emotion labels.     

Does High School Employment Develop Marketable Skills?

While decades of academic research have consistently demonstrated a positive relationship between high school employment and adult earnings, the literature is empirically silent in regards to why this association exists. This study uses data from the National Longitudinal Survey of Youth 1997 (NLSY97) to examine the hypothesis that high school employment develops “marketable skills” in the form of occupation-specific human capital. By analyzing wage variation attributable to the commonality of skill portfolios across respondents’ high school and adult (age 20 and 23) occupations, this study fails to find consistent evidence that the types of skills utilized in high school employment are correlated with adult earnings. Within the framework of the human capital model, this would suggest that the positive, post-school economic gains of in-school work are largely attributable to increases in general human capital (e.g., workplace socialization, character building).

Cost-effectiveness of family-based substance abuse treatment

In order to compete in a financially sensitive health care system, family systems-based treatments must demonstrate effective clinical results as well as cost-effectiveness. Cost-effectiveness research can demonstrate to health care insurers and policy makers which treatments are viable options for implementation. The present literature review identified eight cost-effectiveness family-based substance abuse treatment studies. The results suggest that certain family-based treatments are cost-effective and warrant consideration for inclusion in health care delivery systems.     

Developing a strategy for an Industrial Training Board—a participative approach

The article presents the experience of the authors of designing and working in a participative strategic review and decision making process which involved representatives of employers, trade unions and education; and the analysis and presentation of the results on behalf of an Industry Training Board (a government funded organization) to the Manpower Services Commission, its parent body and link to Government. It considers past practice and the new approach adopted in October 1975, with particular reference to: The Overall Programme of Activities The Review Process The Strategic Workshop Process and gives the authors' conclusions and thoughts to date on the results together with possible developments and improvements to both the process and their own organization's future strategy.     

The Globalization of Penal Space in Nineteenth-Century Malta

In the second half of the nineteenth century an unprecedented number of prisons were built across the Western-influenced world. However, many more developed from repurposed and modified buildings. By applying space syntax analysis to examples from the then British colony of Malta, this article investigates the commonalities of penal space across a series of purpose-built and refashioned prisons, taking into consideration key architectural phases resulting from remodelling. Rejecting the notion that Maltese developments are merely symptomatic of British colonialism, the spread of Western prisons is cast in terms of wider trends and the global spread of a particular type of penal space.
