This paper reports on the development of FRA (Financial Report Analyst), an intelligent, multimedia educational software system which is designed to teach financial statement analysis to business students and professional trainees. FRA is based on a new kind of teaching architecture called a goal-based scenario, a “learning by doing” environment in which the student acts in a realistic role and obtains helpful coaching while performing assigned tasks. In FRA, the student plays the role of a lending analyst at a bank who must make important commercial lending decisions. Usability tests of FRA have been conducted with students in the Kellogg Graduate School of Management at Northwestern University. The paper discusses: theoretical advantages of goal-based scenarios; the architecture of FRA; and ongoing and future research. 相似文献

This article provides a critical assessment of the line of research that measures speculative and hedging activities in futures markets from volume and open interest data. It makes several contributions. First, a detailed theoretical analysis of the measures proposed in the previous literature as proxies for speculative activity clarifies the circumstances in which they fail, as well as the assumptions that have to be made, when they are used as intended. Second, we propose a new way of combining the volume and the open interest figures, which provides additional information regarding the type of trading activity that takes place in the market on a given date. Finally, we analyse empirically the basic statistical properties of all the ratios when they are applied to real data for some of the stock index futures contracts most actively traded in the world. This empirical analysis shows the diverse behaviour of the ratios when they are applied to a common sample of real data, which confirms our previous theoretical findings. Our contributions should be taken into account when any of the measures is used as a proxy for the relative importance of speculative demand in empirical analyses. 相似文献

The propensity of the forecasts of sell-side financial analysts to converge (or diverge) is a function of their exogenous and endogenous selective attention and overconfidence. When returns are negative, the endogenous form of selective attention—a static measure of analysts’ goal-driven attention at a particular point in time—has a positive association with convergence. The exogenous form of selective attention—a relatively involuntary dynamic process of exogenous attentional shift driven by external changes in the market over time—is associated with a tendency for forecasts to diverge. 相似文献

This paper aims to look into the moderating effect of individual's cultural characteristics—Power Distance—on the relationship between the use of discounts and gifts and the formation of the brand equity of a heritage tourist site is assessed. The results of a quasi-experimental 2×2 factorial design among Internet users from two countries and using two different promotional stimuli showed: a positive effect of sales promotions on social media on the formation of brand equity of a heritage tourist site; a lesser effect of online price discounts than free gifts; the moderating role of Power Distance on the formation of brand equity. 相似文献

Is greenwashing a concept describing companies using misleading communication or is it co‐constructed in the eye of the beholder? By discussing the literature, we find that existing definitions of greenwashing overemphasize the strategic intention to mislead and do not incorporate unjust allegations. Then, by combining signaling theory with legitimacy theory, we frame the communication process of the greenwashing accusation and the emergence of a negative narrative caused by the accusation and its effect on legitimacy. Hence, in this paper we argue that greenwashing epistemologically is constituted in the eye of the beholder , depending on an external accusation. Following this view, the greenwashing accusation is understood as a distortion factor altering the signal reliability of green messages. Based on our conceptual analysis, we provide a conceptual framework introducing a new typology of case‐based greenwashing (greenwashing , false greenwashing , potential greenwashing and no greenwashing ) and the effects of these types on corporate legitimacy. Finally, we propose a revised definition of greenwashing as co‐creation of an external accusation toward an organization with regard to presenting a misleading green message.

Objective: To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients.Methods: The Premier Hospital Database was utilized to estimate the number of SRSE cases based on hospital discharges during 2012. Discharges were classified as SRSE cases based on an algorithm using seizure-related International Classification of Diseases-9 (ICD-9) codes, Intensive Care Unit (ICU) length of stay (LOS), and treatment protocols (e.g. benzodiazepines, anti-epileptic drugs (AEDs), and ventilator use). Secondary analyses were conducted using more restrictive algorithms for SRSE.Results: A total of 6,325 hospital discharges were classified as SRSE cases from a total of 5,300,000 hospital discharges. Applying a weighting based on hospital characteristics and 2012?US demographics, this projected to an estimated 41,156 cases of SRSE in the US during 2012, an estimated incidence rate of ~13/100,000 annually for SRSE in the US. Secondary analyses using stricter SRSE algorithms resulted in estimated incidence rates of ~11/100,000 and 8/100,000 annually. The mean LOS for SRSE hospitalizations was 16.5 days (median =11; interquartile range [IQR]?=?6–20), and the mean ICU LOS was 9.3 days (median =6; IQR =3–12). The mean cost of an SRSE hospitalization was $51,247 (median = $33,294; 95% CI = $49,634–$52,861).Limitations: The analysis uses ICD-9 diagnostic codes and claims information, and there are inherent limitations in any methodology based on treatment protocol, which created challenges in distinguishing with complete accuracy between SRSE, RSE, and SE on the basis of care patterns in the database.Conclusion: SRSE is associated with high mortality and morbidity, which place a high burden on healthcare resources. Projections based upon the findings of this study suggest an estimated 25,821–41,959 cases of SRSE may occur in the US each year, but more in-depth studies are required. 相似文献

In the literature on European monetary integration Germany and Italy are mostly strongly contrasted. However, this paper argues that there were important similarities between the policy paradigms in these two countries, in particular if a broader historical perspective is adopted. This work analyses the policy paradigms towards European monetary integration in Italy and Germany. Moreover, it contextualises these paradigms into the national institutional setting: while Germany was characterised by power sharing institutions, Italy featured power fragmentation (something which also affected the economic performance of both countries). There were significant differences between the policy paradigms of foreign policy-makers and economic policy-makers. Foreign policy makers, in both countries, under the influence of a European federalist vision, were strongly in favour of European monetary integration. These beliefs of foreign policy decision makers were crucial in charting EMU policy at history-making moments. The pro EMU policy paradigms of foreign policymakers contrasted, during most of the period covered, with the more sceptical beliefs of economic policy makers. In both countries, economic policy-makers, at different moments, had doubts whether enough “convergence” had been reached to make a more stable exchange rate system sustainable.
