Rules and games

This paper reconsiders the relationship between the rules of a game and its outcomes. We develop a notion of rule reform that leads to the selection of Pareto improved equilibria points. We then apply this notion to a series of naturally occurring fishing rules, including examples from Malaysia, India, Brazil, Turkey, and Canada. We show that reforming a game is conceptually akin to reforming an economy.     

Weekly community interviews with high-risk participants: operational issues

To address several key questions in social science research, repeated interviews of individuals drawn from difficult populations are required. This article describes an approach for addressing the challenges associated with longitudinal interview studies, including locating research participants, obtaining reliable and valid interview data over time, and retaining participants across the course of the study. We applied this approach to conduct a study designed to identify changeable risk factors for violence among high-risk people with mental illness. To successfully conduct weekly interviews of these individuals in the community across a 6-month period, we developed a flexible and personalized interview format; carefully selected, trained, and supervised staff; and developed incentives to maximize participant retention. Each of these three steps is discussed as a guide for future longitudinal studies that involve interviewing difficult populations.     

Gender and Risk Assessment Accuracy: Underestimating Women’s Violence Potential

Understanding factors that contribute to mental health professionals (MHPs) accuracy in assessing patients risk of violence can inform efforts to improve accuracy and to integrate risk assessment technology with practice. Based on a sample of 147 clinicians who assessed 680 patients in a psychiatric emergency room, this study investigates the influence of patient gender, MHP gender, and their potential interaction on MHPS risk assessment accuracy. The results indicate that MHPs of both genders are particularly limited in their ability to assess female patients risk of future violence. This finding was not limited to a particular professional group and was not attributable to gender-related differences in violence. Implications for future research on the judgment processes that may underlie MHPs limited accuracy with women and for training programs in violence risk assessment are discussed.     

Body Size Estimations,Body Dissatisfaction,and Ideal Size Preferences in Children Six Through Thirteen

Results of the second year of a 3-year longitudinal study on children's body size estimations are reported. Participants were 216 male and female children age 6 through 13. Body size estimations were measured using a TV-video methodology. Three psychophysical procedures measured perceived body size, idealized size, and body dissatisfaction. Self-esteem, body esteem, birth order, number of siblings, and parents' socioeconomic status (SES) were measured. Children were accurate in estimating body size, with no gender, age, or ethnic differences. Individual estimations varied greatly over the 1-year test-retest interval. Children had a slight bias to report that their body size was distorted too wide. Both genders wanted to be thinner, with females wanting to be increasingly thinner as they became older. Females were also more dissatisfied with their body size. Taller and heavier children with high SES fathers wanted a thinner idealized body size. Taller, thinner children had less body size dissatisfaction. Children with a larger number of siblings who were one of the first born were more dissatisfied with their body size. Children who gained weight during the previous year without a concomitant growth in height were also more dissatisfied with their body and wanted to be thinner. Body size estimation is viewed as an important aspect of one's body image and is mediated by many different variables, each of which individually explains only a small part of the variance.     

Latent Print Proficiency Testing: An Examination of Test Respondents,Test-Taking Procedures,and Test Characteristics

Proficiency testing is a key component of quality assurance programs within crime laboratories and can help improve laboratory practices. However, current proficiency testing procedures contain significant limitations and can be misinterpreted by examiners and court personnel (Garrett & Mitchell, 2018). To evaluate some of these limitations, we surveyed latent print examiners (n = 198) after they completed a Collaborative Testing Services, Inc. proficiency test. Additionally, we evaluated test performance and used a quality metric algorithm to evaluate the quality of test prints. Results do not suggest that respondents are dissimilar to the broader examiner population, although they may engage in different behaviors when completing tests versus casework. Findings show that proficiency testing contains prints of high quality and is perceived as both relatively easy and representative of casework. The test discriminated between inexperienced and experienced respondents, and verification procedures were largely ineffective in reducing errors. Objective quality metrics may provide a path forward to improving proficiency testing in a measurable manner.
