Odor identification impairments in schizophrenia: relationship with demographic measures, clinical variables, and diagnostic subtypes

Smell identification deficits are consistently found in schizophrenia (SZ), but little is known about the nature and characterization of this deficit or its relationship to the phenomenology of the illness. This study aims to further delineate smell identification errors in SZ by examining the relationship of patient demographic differences with smell-identification performance. Our results showed that a patient's gender and education were related to odor-identification scores, with better performance seen in female patients and in those with greater educational attainment. However, there was no effect related to age, ethnicity, or socioeconomic status on odor identification. A smell identification deficit was also unrelated to clinical characteristics of the patients, including age at first hospitalization, number of psychiatric hospitalizations, and duration of illness. Odor identification also did not differ by SZ subtype, nor between SZ and schizoaffective disorder patients. These findings emphasize that odor identification deficits in SZ are unrelated to clinical illness features, cannot be explained by other confounds related to olfaction in the general population, and may be core features related to the SZ disease process.     

Two Types of Features: An Aristotelian Approach

A certain theory of substance, one that grows out of Aristotelian philosophy but which has adherents today as well, draws a distinction between the features a substance has by instantiating a universal and the features it has by possessing a trope. An adherent of this theory might say that a certain cat is red because it possesses a redness‐trope, but that it is a cat because it instantiates the universal CAT. A problem that must be faced by philosophers who hold this sort of view is the following: Which features are which? In other words, which features are the ones had in virtue of trope‐possession, and which are the ones had in virtue of instantiation? In this paper I discuss this problem, consider and reject a competing view, and propose my own Aristotelian solution. I also raise and answer an objection.     

The Development of a Measure of Irrational/Rational Beliefs

The Attitudes and Belief Scale-2 (ABS-2) developed in the late 1980s, is a measure of Ellis’ irrational and rational beliefs. Although no publication has described the instrument and it has only appeared in conference presentations, many researchers have used the ABS-2 to test REBT. This article describes the development of the ABS-2 and the original research on its psychometric properties. The scale has three factors that represent 24 different cells in a 4 × 2 × 3 factorial model. The first factor, Cognitive Processes, reflects Ellis’ concepts of Demandingness, Awfulizing, Frustration Intolerance, and Self-Downing. The second factor covers irrationally worded items versus rationally worded items. The rationally worded items were written to counter the irrational beliefs. The third factor includes content or life themes about which the person could be concerned, and includes Achievement, Affiliation, and Comfort. The ABS-2 generates a Total Score, a Total Irrationality Score, a Total Rationality score, and Scales scores representing each of the four Cognitive Processes domains and each of the three Content domains. The ABS-2 scores demonstrate adequate to excellent internal consistency, and correlate significantly with measures of depression, anxiety, life satisfaction, selfcontrol, well-being, and measures of internalizing personality disorders. The ABS-2 did not correlate significantly with measures of anger, externalizing personality disorders, mania, and somatoform disorder. An exploratory factor analysis provided weak support for the factor structure of the scale. The ABS-2 scores distinguish between normal and clinical samples. Rationally worded items discriminated between clinical and nonclinical groups much better than did the irrationally worded scales, suggesting that instruments that only assess irrational beliefs might underestimate the support for REBT.     

What Makes Muslim Women Entrepreneurs Successful? A Field Study Examining Religiosity and Social Capital in Tunisia

The present study sheds light upon critical factors that help explain the entrepreneurial success among Muslim women living in a democratic Tunisia, a Muslim-majority country considered by many to be the lone Arab Spring success story. We hypothesized that successful entrepreneurs need social capital, including the capital that comes from marriage and high levels of wasta (the Arabic concept of having personal connections with influential others). Moreover, given the lack of empirical attention paid to the role of the culture, language, and customs associated with Islam on women’s empowerment, we examine whether religiosity is related to entrepreneurial performance among Tunisian women. Data collected with 84 female entrepreneurs participating in entrepreneurship training programs across Tunisia reveal that two forms of social capital, marital status and wasta, are related to training center directors’ ratings of women entrepreneurs’ performance, suggesting that social capital is a critical asset for Muslim women entrepreneurs. Religiosity, on the other hand, had no statistically significant relationship with entrepreneurial performance. Our study contributes to research on entrepreneurship by identifying wasta as a form of social capital that may be necessary for women entrepreneurs to succeed in the Middle East and North Africa and by taking an initial step towards better understanding the empirical (and controversial) relationship between religiosity and career success among Muslim women. We recommend that training organizations supporting entrepreneurs directly assist women in the development of social capital and acknowledge, rather than ignore, that nepotism and wasta are linked to entrepreneurial success in some cultures.
