Performance of different organizations, such as hospitals is mainly influenced by their managers' performance. Nursing managers have an important role in hospital performance and their managerial skills can improve the quality of the services. Hence, the present study was conducted in order to assess the relationship between the managerial skills and the results of their performance evaluation ...

This paper investigates the impact of asset liquidity on the valuation of corporate securities and the firm’s financing decisions. I show that asset liquidity increases debt capacity only when bond covenants restrict the disposition of assets. By contrast, I demonstrate that, with unsecured debt, greater liquidity increases credit spreads on corporate debt and reduces optimal leverage. The mode...

The main objective of this article is to present a comparative study of capital assets pricing models (CAPM) with extrapolating capital assets pricing models (X-CAPM) of companies admitted in Tehran Exchange Market which is accomplished for the first time by investigators of this research in Iran. Accordingly, the statistical population under study of this research includes all companies admitt...

A comparative analysis of the efficiency of correlation (cross-correlation, Tanimoto coefficient and Kendall's rank correlation coefficient) and information (mutual information of Tsallis and Shannon, F-information measure and entropy of the joint probability distribution) measures of image similarity for the synthesis of recursive estimation algorithms is presented for the problem of estimatin...

In this paper, a covariance matrix of circulant correlation, R, is studied. A pattern of entries in R−1 independent of the value ρ of the correlation coefficient is proved based on a recursive relation among the entries of R−1. The D-optimal design for simple linear regression with circulantly correlated observations on [a, b] (a < b) is obtained if even observations are taken and the correlati...
