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 article examines the expansion of the soybean complex in South America and the role of Chinese firms in expanding their presence in different sectors of the oilseed complex. The growth in trade relations between the two parties has been built on the export of primary commodities from South America and the import of Chinese manufactures—a trade pattern that reproduces core‐periphery dynamics identified by dependency theory scholars. Of particular importance in this bilateral trade is soybean, a crop that has been consolidated as the main export for several South American countries, fuelled by growing demand from China. This article explores China's role in the global political economy as a key agri‐business player and the implications for new relations of dependency by studying the strategies deployed by Chinese firms to increase their influence in the governance of the soybean nexus. 相似文献

The paper seeks to examine some of the key features of Karl Polanyi’s ideas explaining the collapse of the pre-Great Depression unregulated market system by using his broad framework of analysis, as developed in The Great Transformation and published over 70 years ago, to explain the present Eurozone crisis. Emphasis is placed on the two key institutions of the pre-Depression era, namely haute finance and the gold standard, as well as his heterodox views on the nature and origin of money to shed light on the evolving crisis within the Eurozone. On the basis of Polanyi’s insights, the paper concludes that the cause of the latter crisis is similar and it lies primarily in the adoption of stateless or supra-national money that is even more restrictive on the behaviour of national authorities than the conditions imposed under the gold standard. The current situation of quasi-permanent austerity in the Eurozone is the inevitable consequence of its monetary architecture, and it will remain a long-term feature of Europe, unless significant institutional changes are put in place to bridge the gap between money and the state. 相似文献

This article has the aim of presenting the basis for a new, clearer classification of restaurant attributes. The research followed an interpretive approach with a systematic review of the literature, compared and contrasted with the findings of six focus group interviews. A new model was devised with seven categories of restaurant attributes. This article presents a model that needs to be tested. Also, follow-up articles with more detail about the attributes under each category will be presented. This article organizes the disparate literature on restaurant attributes and looks into the relationship between attributes, particularly its influence on perceived consumer value. 相似文献

Are Flexible Exchange Rate Regimes more Volatile? Panel GARCH Evidence for the G7 and Latin America 下载免费PDF全文
This paper investigates empirically the relationship between exchange rate (ER) regimes and volatility of real exchange rate depreciation (RERD), comparing the G7 and 17 Latin American (LA17) countries, during 1970–2010. We estimate a panel autoregressive model with generalized autoregressive conditional heteroskedasticity (GARCH) errors and regime‐specific effects on both the conditional mean and conditional variance. For the G7, we find that, relative to the fixed ER regime, only the freely floating regime shows higher RERD volatility; under the managed floating regime the RERD is equally volatile and under the crawling peg it is actually less volatile. Instead, in the case of the LA17, more flexible ER regimes are associated with more volatile RERD rates, with higher volatility under the managed floating regime than under the crawling peg and with extremely high volatility under the “freely falling” ER regime. 相似文献

This paper explores the extent to which discrimination against foreign applicants in the trademark registration process can be used as a “behind‐the‐border” barrier to imports. Prima‐facie evidence shows that in some developing countries the ratio of trademark registrations to applications is much higher for national than for foreign applicants, which is consistent with the notion of discrimination against foreign firms. A simple model is developed that suggests that incentives to discriminate are stronger when foreign firms manufacture products that are close in quality to the goods produced by domestic firms. This hypothesis is then tested and empirically confirmed in three of the four countries in our sample, suggesting that discretion and discrimination in the trademark registration process can sometimes be used as a protectionist tool. 相似文献

This study draws on the Resource‐Based View to analyze the effects of distinctive competences in tourism firms and location in a tourism district on competitive position, and explores the moderating effects of the tourism destination. Multiple linear regression was used to test the research hypotheses on a sample of 1019 Spanish tourism firms. Results reveal that financial resources and dynamic and production capabilities favor a better competitive position for tourism firms in general; however, coordination and marketing capabilities are key factors for firms embedded in a tourism district, while dynamic capabilities have a negative effect in this case.

The major countries of the former Soviet Union—specifically Russia, Ukraine, and Kazakhstan—are becoming increasingly important in world agricultural markets. The two main developments are that this region has become a large grain exporter, especially of wheat and barley, and Russia a big agricultural importer, especially of meat. These trends should continue for the next decade. However, policies to expand the livestock sector could mitigate these developments, as increased domestic meat production would reduce both meat imports and surplus feed grain for export. Also, further growth in the region's grain exports will require improvement in the infrastructure for storing and transporting grain. 相似文献

Strategic entrepreneurship captures firms’ efforts to simultaneously excel at opportunity seeking and advantage seeking. But little research exists into mechanisms that might facilitate strategic entrepreneurship. Drawing on the twin concepts of competence exploration and competence exploitation, we study their effects on strategic entrepreneurship. Theoretically, the entrepreneurial components of strategic entrepreneurship (an entrepreneurial mindset and creating innovation) should benefit from competence exploration while its strategic components (managing resources strategically and executing competitive advantages) should benefit from competence exploitation, but not vice-versa. Our findings, however, suggest that this theoretical dichotomy does not hold up in practice. 相似文献
