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 work draws on consumer and psychology research to explain sociocognitive aspects of product-market dynamics at a higher
level of specificity than prior research. The authors extend the field’s understanding of market-shaping shared knowledge
through a theory-informed discussion of how shared product knowledge comes to exist and how it changes as product markets
develop. They define shared knowledge as the aspects of product representations that are common across the minds of market
actors, making it possible for them to understand one another. The authors also discuss ways to track shared knowledge content
that is expressed in market narratives. As the characteristics of shared knowledge are explained and linked to stages of product-market
development, the authors develop a set of researchable propositions to guide future research. The theoretical arguments and
propositions in this article complement extant marketing strategy research by integrating individual-level consumer theory
with market evolution models.

Market relationships are often influenced by factors inside of the firm. Here we examine how the employees' view of corporate reputation of a merged B2B firm, assessed by corporate character (empathy, warmth, integrity and conscientiousness), influences their emotional attachment, satisfaction and job security. Warmth and empathy correlate strongly with satisfaction. Amongst a number of hypothesised ‘proximity’ factors time (e.g. length of service) and space (e.g. work location) had a substantial effect on perceived warmth and empathy. The interaction of the two had the most significant effect on emotional attachment; in that employees working remotely and of longer standing were the most disaffected. We propose the employees' length of service and work location as important factors generally in determining their emotional response to a merger and in predicting where disaffect will be most acute. 相似文献

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case. 相似文献

The role of intellectual capital in the success of new ventures 总被引:1,自引:0,他引:1

Identifying the factors that contribute to the success of new ventures is a difficult and challenging task. In that respect,
this paper proposes an analysis of the intellectual capital within new business ventures. Based on the study of a sample of
130 new companies, for the purpose of this work we have analysed the influence of the proposed intangible assets on the success
of newly-created organizations, acknowledging the key role of the human and relational capital in the first few years of the
life of the business. 相似文献

Analyses were carried out on financial compensation to avoid loss of tropical forests and related carbon (C) emissions when marginal financial yield declined for land-use options with extended areas, and when a risk-averting perspective (modeled according to financial theory around the capital asset pricing model) is assumed. The approach in this study was to consider natural forest, forest plantation, pasture, and cropland simultaneously to investigate how an optimized land-use distribution may reduce the amount of compensation necessary to avoid C emissions from forest loss.The financial compensations derived were as high as US$ 176 per hectare per year when comparing natural forests only with the most profitable alternative (croplands). However, compensation decreased to US$ 124 for risk-neutral decision-makers, who would strive for optimized land-use allocation, and to only US$ 47 per hectare per year for risk-avoiders, who would look to maximize the reward-to-variability ratio. Sensitivity analyses indicated that the compensation under risk-aversion increased much less than under risk-ignoring when increased productivity of agricultural land-use or growing demand for agricultural products was simulated. It was concluded that considering appropriate diversification strategies and the well documented human behavior to avoid risks is an important step in developing cost-effective compensation policies. 相似文献

This paper examines and compares the communication strategies of the Federal Reserve and the European Central Bank, and their effectiveness. First, we find that the surprise components of both monetary policy actions and statements have important but differing effects on asset prices, with unexpected communication having a much greater impact on longer‐term interest rates. Second, both the ECB and the Fed have proven to be equally successful in moving their domestic asset prices using either monetary policy or news shocks. However, the response of the American yield curve to the surprise component of Fed's statements is larger than the reaction of the European term structure to ECB's announcements. This result is intimately related to the amplitude of the policy rate cycle that is much larger in the US than in the euro area combined with the bounded support of the news shock. Third, we analyze the cross‐effects and show that the Fed has been more able to move the European interest rates of all maturities than the ECB to move American rates. This finding is tied to the predominance of dollar fixed income assets rather than to an attempt of the ECB to mimic the Fed. 相似文献

This study seeks to highlight the key role played by relational capital in new business start‐ups. Following a review of previous research examining the success factors of new ventures and the role played by intellectual capital, our study sets out to achieve this objective by analyzing the impact of a set of intangible relational assets on the initial success of new business start‐ups. Based on a study of 130 firms, we analyzed six hypotheses regarding the possible positive relationship between the relational capital of a start‐up company and its success in its first few years of business. 相似文献

Developing markets have increasingly gained prominence in the world economy, but the domestic factors behind this success are not well established. This uncertainty may interfere with multinational expansion plans. In this article, we examine several macroeconomic and institutional factors affecting Brazilian outward foreign direct investment in 17 destination countries. We applied a pooled ordinary least squares regression over the 2001–2014 period. The findings suggest that macroeconomic factors are still statistically significant to explain investment abroad, but several institutional factors such as corruption have emerged, having a negative effect and political violence having a positive effect on Brazilian outward foreign direct investment. 相似文献
