Relevant Restricted Quantification

The paper reviews a number of approaches for handling restricted quantification in relevant logic, and proposes a novel one. This proceeds by introducing a novel kind of enthymematic conditional.     

Incremental validity of the MMPI-A content scales in the prediction of self-reported symptoms

The incremental contribution of the MMPI-A (Butcher et al., 1992) content scales to the prediction of scores on self-report measures of psychopathology was examined in a sample of 62 adolescents in inpatient treatment and 59 adolescents from the community. All participants completed the MMPI-A and a battery of criterion measures. A series of hierarchical regression analyses was conducted in which the MMPI-A clinical and content scales served as the independent variables and the criterion measures as the dependent variables. The content scales were found to have incremental validity beyond the clinical scales in predicting variance in the criterion measures. Similarly, the clinical scales also demonstrated incremental validity over the content scales in making these predictions. Both sets of scales made independent contributions to the prediction of sample membership (clinical vs. nonclinical). Findings suggest that both the clinical and content scales of the MMPI-A make significant contributions to the assessment of adolescents' psychological functioning.     

Effectiveness of NEO-PI-R research validity scales for discriminating analog malingering and genuine psychopathology

We investigated the research validity scales for the NEO Personality Inventory-Revised (NEO-PI-R) proposed by Schinka, Kinder, and Kremer (1997): Positive Presentation Management (PPM) and Negative Presentation Management (NPM). Additionally, an experimental analog to the Minnesota Multiphasic Personality Inventory-2's (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) F-K index was calculated by subtracting the raw score on PPM from the raw score on NPM (NPM-PPM). In 2 studies, all indexes showed significant between-group differences when samples of analog malingerers (n = 97) were contrasted with psychiatric outpatients (n = 272). The sensitivity and specificity of these validity indexes indicated that although none performed well in extremely low base rate environments, the NPM and NPM-PPM indexes showed promise when the base rate of faking bad rose to higher levels.     

The need to reform our assessment of evidence from clinical trials: A commentary

The ideology of evidence-base medicine (EBM) has dramatically altered the way we think, conceptualize, philosophize and practice medicine. One of its major pillars is the appraisal and classification of evidence. Although important and beneficial, this process currently lacks detail and is in need of reform. In particular, it largely focuses on three key dimensions (design, [type I] alpha error and beta [type II] error) to grade the quality of evidence and often omits other crucial aspects of evidence such as biological plausibility, reproducibility, generalizability, temporality, consistency and coherence. It also over-values the randomized trial and meta-analytical techniques, discounts the biasing effect of single centre execution and gives insufficient weight to large and detailed observational studies. Unless these aspects are progressively included into systems for grading, evaluating and classifying evidence and duly empirically assessed (according to the EBM paradigm), the EBM process and movement will remain open to criticism of being more evidence-biased than evidence-based.     

Muslim women, middle class habitus, and modernity in Indonesia

This article asks how pious religious practices, which are often highly gendered, and implicated in diverse formulations of “the modern” in non-Western contexts. Based on ethnographic research among women members of Indonesia's Prosperous Justice Party (PKS), I argue that PKS women’s pious practices are part of the creation of a particular kind of middle class subjectivity. An examination of two constitutive elements of this habitus, clothing and marriage, reveals how these pious Islamic practices enact class and gender difference, and simultaneously produce “modern” selves. While scholars have shown that gender is an important axis for class difference, I extend this argument to suggest that gendered forms of piety are key ways class in which distinctions are embodied and expressed. Yet the habitus of PKS women is just one of several competing Islamic habitus in Indonesia. The question of which habitus is most culturally legitimate, I maintain, turns on the hegemony of particular understandings of piety and ideas about how modernity should be defined–issues which remain unresolved in contemporary Indonesia.

Defining the vital condition for organ donation

Luke Demaitre's Leprosy in Premodern Medicine: A Malady of the Whole Body is a highly interesting study of the medical history of leprosy and the medical and social perceptions on leprosy that have been around for centuries. Remarkably, it is likely that leprosy will disappear from the face of the Earth in our generation, thanks to the development of a curative treatment and its increasing availability (although the battle has not yet been won completely). Demaitre's book is a very good read not only for its information about leprosy but also for all interested in or affected by the social phenomenon of stigma. In illnesses such as leprosy, HIV/AIDS, epilepsy, and mental disorders such as schizophrenia, the stigma attached to the condition may be worse than the condition itself.     

The mediating effect of reflective-analytic cognitive style on rational thought

Abstract

We investigate whether non-miserly cognitive styles mediate the effects of cognitive ability and thinking dispositions on rational thought. Specifically, we review relevant literature on two dimensions that define non-miserly cognitive style: reflection-impulsivity and analytic-intuitive. We use these two dimensions to identify a continuum of cognitive styles that vary from miserly (impulsive-intuitive) to non-miserly (reflective-analytic) and are congruent with tendencies to commit specific rational thinking errors. Further, we argue that this continuum, which we label reflective-analytic cognitive style, mediates the effect of cognitive ability and thinking dispositions on rational thought. We conduct an experiment testing our predictions and find evidence, via structural equation modelling, that reflective-analytic cognitive style does mediate the effect of cognitive ability (as measured by working memory capacity) and thinking dispositions (as measured by need for cognition and actively open-minded thinking) on responses to traditional rational thinking tasks.
