Developing a tutoring module for presentation of computerized patient management problems

The simulation problem is one of the most commonly used formats in computer-assisted instruction (CAI). In medical education, a patient simulation problem is known as a patient management problem (PMP). A number of computerized PMP systems are currently available. However, to date, there is no record of PMP systems having been developed using artificial intelligence. This is noteworthy since artificial intelligence techniques could help in the generation of more effective and intelligent instructional systems.

This paper analyzes and evaluates existing instructional simulation software in clinical medicine in terms of effective educational design attributes. Components of effective PMP systems thus identified are incorporated into a computerized instructional system which uses artificial intelligence techniques for teaching problem-solving and diagnostic skills to undergraduate medical students.     

Estimating the demand for reserve assets across diverse groups of countries

This paper takes a fresh look at the determinants of the holding of reserves with the aim of highlighting similarities and differences among emerging markets (EMs), advanced economies (AEs), and low‐income countries (LICs). We apply two panel estimation techniques: fixed effects (FE) and common correlated effects pooled mean group (CCEPMG). FE regression results suggest that precautionary savings’ motives, both current account‐ and capital account‐related, are generally the most important determinants of reserves’ holding for all country groups. Nonetheless, there is considerable heterogeneity across country groups and over time. The intertemporal motive, a novelty of this paper, has gained importance everywhere. The CCEPMG results confirm the importance of precautionary motives and suggest that current account motives matter only for EMs and LICs and capital account motives matter for all groups while being more relevant for EMs. The CCEPMG results also point to the importance of taking into account the heterogeneous impact of unobserved common factors that affect coefficient estimates and the dynamic process through which reserves adjust to changes.     

Comparing Interpersonal Comparisons in Utility Theory and Happiness Research

Social scientists are reluctant to make explicit interpersonal comparisons of well-being. However, implicit comparisons are made on a surprisingly regular basis. These comparisons are based on the wealth and the Kaldor–Hicks concept in utility theory and on self-reported well-being in happiness research. Taking a utilitarian stance, this paper tests the ethical foundations of both principles. While self-reported well-being serves as an acceptable proxy for utilitarian decision-making, the Kaldor–Hicks concept does not appear so. Implications for evaluating policies are outlined.

Participation in Community Leisure Programs: Experiences and Perspectives of Children with Developmental Difficulties and Their Parents

Children with developmental disabilities participate in more solitary, sedentary, and home-based leisure activities than active physical pursuits or community-based activities. Clinical experience suggests that children with less well-recognized developmental difficulties also have compromised leisure experiences; however, this has not been fully investigated. This study engaged 20 school-age children with developmental difficulties in a community-based circus program, designed in collaboration with occupational therapists. The program included activities such as trampolining, trapeze, and acrobatics. Semi-structured interviews with children and parents explored children's leisure experiences both at circus and more broadly. Qualitative content analysis revealed that friendships, having fun, and being physically active were highly valued aspects of leisure. The coaching style and “just right” level of challenge within programs were identified as central to children's engagement and sense of competence. Participating in a supported leisure program such as circus appeared to promote children's engagement in community leisure, at least in the short term.     

Sustaining Collusion Via a Fuzzy Trigger

Probability theory is the standard economic representation of uncertainty, although it is not always an accurate one. Fuzzy logic is an alternative representation that does not require individual beliefs regarding the explicit functional form of uncertainty. This paper applies fuzzy logic to an oligopoly trigger pricing game. The fuzzy trigger pricing game reverses the standard cyclical price war prediction; collusion-sustaining price wars are most likely to occur during times of high demand. The fuzzy model also predicts that markets with relatively volatile prices are more likely to undergo collusion-sustaining price wars. The predictions are consistent with available empirical evidence.     

Daily income target effects: Evidence from a large sample of professional commodities traders

We provide evidence of rational reference-dependent preferences in the proprietary trading of professional traders. We find increased trading effort and risk taking by traders following morning losses. Further analysis provides no evidence of a deterioration in trading performance subsequent to losses, as neither risk-adjusted performance nor trade execution appear to be negatively affected by prior losses. The evidence supports the existence of rational reference-dependent preferences in the form of trader daily income targets: these professional traders exhibit increased work effort subsequent to abnormal morning losses. The evidence is inconsistent with the alternative explanation of costly loss aversion.     

Assessment of Leading Apparel Specialty Retailers’ CSR Practices as Communicated on Corporate Websites: Problems and Opportunities

Despite the increased attention to corporate social responsibility (CSR) and regulatory changes in recent years, little is known about how apparel companies are implementing and communicating CSR practices to their stakeholders. To fill the gap, this study investigated the range and strategies of leading apparel specialty retailers’ CSR practices as communicated on their websites over a longitudinal period of 1 year. In total, 17 apparel specialty retailers were included in the analysis. The companies’ websites were content-analyzed in-depth using the coding criteria focusing on labor and environmental issues developed for this study. The initial data were collected in November 2011 and the study was replicated in December 2012 to examine any changes in the CSR practices. As of 2011 only nine companies addressed CSR issues on their websites at different degrees despite their leadership positions in the industry. Environmental issues were addressed by only five companies, with different ranges of practices. In 2012, all 17 companies addressed labor issues on their websites with varying degrees of specificity. In terms of environmental issues, six companies (an increase of one company from 2011) addressed environmental initiatives on their websites with wider ranges of practices. Discussed are problems and opportunities, as well as the role of the government and stakeholders, for the effective communications of CSR policies and initiatives for the apparel industry.
