abstract the aim of this study is of the effect of structural changes in higher education on changes of output in sistan and baluchestan province using structural decomposition analysis (sda). the input-output tables of this region for the period 2006-2011 have been employed as the database of the model. the structural changes were decomposed into two factors: changes in share of specific secto...

In this paper, we propose a supervised method for color image classification based on a multilevel sigmoidal neural network (MSNN) model. In this method, images are classified into five categories, i.e., “Car”, “Building”, “Mountain”, “Farm” and “Coast”. This classification is performed without any segmentation processes. To verify the learning capabilities of the proposed method, we compare ou...

We introduce a factor approach to performance measurement of global ESG equity investments. construct pure portfolios (PFP) following Fama-MacBeth; then, applying Fama-French (FF) spanning regressions that simultaneously test and the validity adding new factors FF 5-factor model. To address endogeneity, we use GMM-IV estimator. Our do not generate significant alphas during 2015-2019, corroborat...

We study the predictive power of approximately 2.5 million stock picks submitted by individual users to the “CAPS” website run by the Motley Fool company (www.caps.fool.com). These picks prove to be surprisingly informative about future stock prices. Indeed, a strategy of shorting stocks with a disproportionate number of negative picks on the site and buying stocks with a disproportionate numbe...

In this paper, we apply the FM methodology to the cross-section of Romanian-listed common stocks and investigate the explanatory power of market beta on the cross-section of commons stock returns from Bucharest Stock Exchange. Various assumptions are empirically tested, such us linearity, market efficiency, the “no systematic effect of non-beta risk” hypothesis or the positive expected risk-ret...

An effort estimation model is needed for softwareintensive projects that consist of hardware, embedded software or some combination of the two, as well as high level software solutions. This paper first focuses on functional decomposition techniques to measure functional complexity of a computer system and investigates its impact on system development effort. Later, it examines effects of techn...
