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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Zusammenfassung Der wertorientierte Ansatz der Unternehmensführung gewinnt immer mehr an Bedeutung; damit w?chst auch der Rechtfertigungsdruck
für Aufwendungen des Dialogmarketing. Um den Ansprüchen der Wertorientierung Rechnung tragen zu k?nnen, muss das Dialogmarketingcontrolling
neu ausgerichtet werden. In diesem Beitrag lesen Sie, wie ein Analyse- und Gestaltungsrahmen für ein wertorientiertes Dialogmarketing
aussehen und wie Wertorientierung im Dialogmarketingmanagement erfolgen kann.

Our purpose is to answer two questions pertinent to the international transmission of changes in equity values. First, do lead-lag relationships documented in short-horizon (daily) studies continue to hold in longer time (monthly) horizons? Second, does the lead-lag structure remain stable over time? The questions are answered by examining monthly equity returns for nine countries during the 1980s. We find evidence that is somewhat surprising—significant lead-lag relationships among some countries persist in monthly horizons, particularly during the first half of the 1980s. During the second half, the lead-lag relationships are substantially weaker. During the same period, we find that contemporaneous correlations across countries have largely increased, implying greater influence of worldwide factors in determining equity prices. 相似文献
