Semi-strong form efficiency is generally supported by event studies, especially these on daily returns testing the market's reaction to accounting earnings. Nevertheless, the Post-Earnings-Announcement Drift (PEAD) anomaly, being inconsistent with semi-strong form efficiency, seems to have survived robustness tests through the years. This paper examines the reaction of ATHEX in response to fiscal year 2006 annual earnings announcements of 20 high capitalisation companies. The common event study methodology is being used in order to define expected returns and trace the abnormal performance of ...

For centuries, we have known that our dynamic universe is adorned by cosmic fireworks: energetic and ephemeral beacons of light from a single star that are a million (nova) to a billion (supernova) times brighter than our sun. However, it had been an age-old conundrum that the brightest nova is approximately 1000 times fainter than the faintest supernova; why should nature leave such a wide "gap"? In search of an answer, I undertook three systematic surveys for my thesis. Since I was looking for transients fainter, faster and rarer than supernovae, I focused my search on galaxies in the loc...

In the United States, divorce is estimated to occur in approximately 50% of all marriages. As a result, children are increasingly being exposed to the divorce process and are at increased risk for emotional and behavioral difficulties. The maternal preference for child placement following a divorce is well documented and often places fathers in the role of the nonresidential parent. Parent-child relationships frequently continue after divorce and fathers have been shown to play a critical role in child development. Factors that contribute to the quality of the nonresident father-child relation...

This paper seeks to analyze the role that literature has performed throughout the last years, the conflicts derived from the academic views, and how literature is an essential tool for the comprehensive study of a second language, as an integral part of the educational process. The Model suggested enhances the figure of the teacher and promotes the skills, knowledge and attitudes of the students within a multicultural environment.

Immigrants are characterized on the average with higher human capital and are rewarded potentially less as compared to their native counterparts. This question has motivated me to analyze the immigrants-natives wage gap in detail and find the extent of this potential discrimination against the immigrants. I analyze the data from the first two quarters of the Quarterly Labour Force Survey, 2009 using the Oaxaca Decomposition technique. Applying both the threefold and twofold decomposition approaches, I computed the wage gap first using simple decomposition based on threefold and then the twofol...

The purpose of this study was to examine the complexities of successful attainment and achievement of 10 Mexican American males in a rural Southwest community college. This study strives to offer insights concerning the questions: (a) what behavioral patterns of current family, peers, and conditions in school have influenced the educational decisions of these Mexican American males? and (b) what social conditions motivate these Mexican American males to seek and achieve higher education despite adversity? This qualitative research was also aimed at establishing and understanding how a selec...

The aim of this study was to establish what is known about the treatment of schizoid personality disorder using psychodynamic psychotherapies, by conducting a systematic review of the literature. The limitations of this approach are set out, followed by an account of the development of the use of the term in descriptive psychiatry and the psychodynamic literature. The inclusion criteria used were studies in English and of adults, that had a methodology, had confirmed a diagnosis of schizoid personality disorder in the subject during the study, that used any type of psychodynamic approach, and ...

This paper aims to analyze the relations between the European Union, the projection of its values through the European Neighbourhood Policy (ENP), and the contribution of the local non-governmental organizations (NGOs) to the process of accepting, internalizing and spreading the values of the EU in the Republic of Moldova. The context in which this paper is elaborated was set by Moldova's inclusion in the ENP, the political debate generated by the possibility of future EU integration, and the Communists' loss of power in July 2009. The main idea underpinning the entire research process is that...

Salvia divinorum is a hallucinogenic herb that was originally used in the Mazatec Indian culture of Oaxaca, Mexico for spiritual and medicinal purposes (Wasson, 1962). Salvia divinorum produces powerful hallucinogenic effects when the leaves are chewed, orally consumed in a liquid state, or dried and smoked. Its active ingredient is Salvinorin-A (Roth et al., 2002; Siebert, 1994), a highly selective kappa-opioid receptor agonist (Roth et al., 2002), that researchers consider to be the most potent naturally occurring hallucinogen (Ortega, Blount & Manchand, 1982; Siebert, 1994; Valdes et al., 1...
