This paper explores ramifications of quasirational behavior in capital markets. Despite the academic literature asserting that financial markets are efficient and humans are rational agents, there is a widespread discontentment among practitioners and a growing body of researchers that neither of those premises is valid. The increasing amount of empirical evidence against perfectly efficient ca...

Sexual self-perceptions are important aspects of sexuality, which can undergo significant change during adolescence and early adulthood. The purpose of this study was to describe these changes among girls (N = 251; ages 16-25) over one year, and to examine associations of sexual self-perceptions (sexual subjectivity) with age, sexual behavior, and romantic status. Sexual body-esteem, perception...

I argue that some cases of delusions show the inadequacy of those theories of interpretation that rely on a necessary rationality constraint on belief ascription. In particular I challenge the view that irrational beliefs can be ascribed only against a general background of rationality. Subjects affected by delusions seem to be genuine believers and their behaviour can be successfully explained...

Rationality of early release data is typically tested using linear regressions. Thus, failure to reject the null does not rule out the possibility of nonlinear dependence. This paper proposes two tests that have power against generic nonlinear alternatives. A Monte Carlo study shows that the suggested tests have good finite sample properties. Additionally, we carry out an empirical illustration...

mega city-regions or metropolitan regions- that was introduced for the first time in a cabinet article in 1995- are becoming a dominant form of human settlements both in developed and developing countries. despite of all contentious discussion on economic and demographic significance of metropolitan regions and so rationality of establishing a distinct structure for their effective management a...

Do violations of classical rationality theory imply that agents are acting against their self-interest? To answer this question, we investigate whether completeness and transitivity necessarily hold when agents choose outcome rationally—that is, their choice sequences do not lead to dominated outcomes. We show that, because of the danger of money pumps and other manipulations, outcome rationali...

Rational analysis (Anderson 1990, 1991a) is an empirical program of attempting to explain why the cognitive system is adaptive, with respect to its goals and the structure of its environment. We argue that rational analysis has two important implications for philosophical debate concerning rationality. First, rational analysis provides a model for the relationship between formal principles of r...

Though much research has been conducted on Subjectivity and Sentiment Analysis (SSA) during the last decade, little work has focused on Arabic. In this work, we focus on SSA for both Modern Standard Arabic (MSA) news articles and dialectal Arabic microblogs from Twitter. We showcase some of the challenges associated with SSA on microblogs. We adopted a random graph walk approach to extend the A...
