Doppler echocardiographic changes found in diastolic dysfunction

Diastolic dysfunction may be associated with increased morbidity and mortality. In this article, an overview of the pathophysiology of diastolic dysfunction is discussed and the findings of Doppler echocardiography used to aid in its diagnosis are reviewed.     

Heat-related deaths

Risk factors and criteria for classifying deaths as heat related are discussed with emphasis on investigation of the circumstances.     

Using disaster planning to optimize expenditures on financial safety nets

Using a multiperiod model, this paper offers a benchmark standard for efficient safety net management. This standard embodies a market-mimicking strategy for identifying, preventing, and resolving bank insolvencies. Around the world, governmental reluctance to acknowledge weaknesses in their crisis prevention efforts supports an underinvestment in contingent plans for handling financial disaster. The model features the hypothesis that this underinvestment misserves taxpayers by increasing the ability of stakeholders in insolvent banks to extract implicit and explicit subsidies when and as the threat of an actual crisis intensifies.The William S.

Ratio Analysis Using Rank Transformation

This paper presents an alternate method for transforming financial ratios. Ratios are ranked and scaled into a uniform distribution with boundaries between 0 and 1. Conceptually, we suggest that this method solves a number of methodological problems associated with ratios, including constrained choice of regression models, ratio outliers, negative ratios, and non-normal distributions. Scaled ranks of financial ratios are also conceptually appealing because they appear to capture comparative ordinal data about cross-sectional relationships between firms.The study empirically tests scaled rank transformations by examining the association of the transformations with stock returns. Results show that models using relative ranked accounting ratios have more explanatory and predictive power than untransformed, log-transformed and square-root transformed ratios.     

The Structure of the Introductory Economics Course in United States Colleges

The authors examine class size, teaching methods, and the one-semester/two-semester organization of the first course in economics, where colleges and universities are classified into five broad categories, from liberal arts colleges to research institutions. Student satisfaction with respect to their institution is also reported.
