Iterated belief change based on epistemic entrenchment

In this paper it is argued that, in order to solve the problem of iterated belief change, both the belief state and its input should be represented as epistemic entrenchment (EE) relations. A belief revision operation is constructed that updates a given EE relation to a new one in light of an evidential EE relation. It is shown that the operation in question satisfies generalized versions of the Gärdenfors revision postulates. The account offered is motivated by Spohn's ordinal conditionalization functions, and can be seen as the Jeffrization of a proposal considered by Rott.I am indebted John G. Bennett and Henry E.

The Effects of Educational Diversity in a National Sample of Law Students: Fitting Multilevel Latent Variable Models in Data With Categorical Indicators

Controversy surrounding the use of race-conscious admissions can be partially resolved with improved empirical knowledge of the effects of racial diversity in educational settings. We use a national sample of law students nested in 64 law schools to test the complex and largely untested theory regarding the effects of educational diversity on student outcomes. Social scientists who study these outcomes frequently encounter both latent variables and nested data within a single analysis. Yet, until recently, an appropriate modeling technique has been computationally infeasible, and consequently few applied researchers have estimated appropriate models to test their theories, sometimes limiting the scope of their research question. Our results, based on disaggregated multilevel structural equation models, show that racial diversity is related to a reduction in prejudiced attitudes and increased perceived exposure to diverse ideas and that these effects are mediated by more frequent interpersonal contact with diverse peers. These findings provide support for the idea that administrative manipulation of educational diversity may lead to improved student outcomes. Admitting a racially/ethnically diverse student body provides an educational experience that encourages increased exposure to diverse ideas and belief systems.     

The relationship of childhood trauma to nicotine dependence in pregnant smokers

Pregnant women with high levels of nicotine dependence are the least likely to quit smoking spontaneously during pregnancy or to benefit from smoking cessation interventions. In the general population, there is increasing evidence of a relationship between smoking, nicotine dependence, and exposure to childhood trauma. We examined the relationship of childhood trauma to several measures of nicotine dependence and evaluated whether this relationship was mediated by major depressive disorder or depressive symptom severity in pregnant smokers. Moderate to extreme levels of childhood trauma were significantly related to smoking within 5 minutes or less of waking, and to the Behavioral Choice-Melioration, Negative Reinforcement, and Tolerance subscales of the Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) scale. The relationships between childhood emotional abuse and the WISDM-68 Total and Negative Reinforcement subscale were partially mediated by depressive symptoms. Results suggest that childhood trauma may be a risk factor underlying nicotine dependence in pregnant smokers. Increased understanding of the relationship of affect regulation to smoking in individuals with childhood trauma histories may aid in the development of more effective treatments of nicotine dependence for this population of smokers.     

Modernity and childrearing in families of Gujarati Indian adolescents

Over the last two decades, researchers have devoted increasing attention to the role of cognitive factors in parenting. These cognitive mediational models focus on the role of attitudes, beliefs, and knowledge in influencing parenting behaviours. A cognitive factor that contributes to cultural variation in parenting is attitudinal modernity—a broad concept that refers to the “Westernization” of attitudes in such diverse areas as gender role conceptions, political attitudes, attitudes toward authority, the family, and religious beliefs. Modernity has been most useful in describing the attitudes of individuals from countries undergoing the rapid social and economic changes that accompany industrialism and urbanization. The present study focused on India—a country currently undergoing such changes. Despite the wide range of modern and traditional beliefs among contemporary Indian parents, our understanding of the determinants of these individual differences is limited. The purpose of the present study was to examine the relation between modernity and parental childrearing practices, as well as to examine the relation between adolescent modernity and parental childrearing. Mothers, fathers, and adolescents in 50 Hindu, Gujarati families completed questionnaires about the modernity of their attitudes and were interviewed about parental childrearing practices. Parental and adolescent modernity were highly correlated. Moreover, parental modernity predicted the nature of parental childrearing values and practices, and parental childrearing values predicted adolescent modernity. Although the findings varied somewhat for mothers versus fathers, parental modernity was associated with individualistic childrearing values and practices, and parents who valued individualistic characteristics in their adolescents had sons and daughters who reported the highest levels of modernity. Implications for understanding the role of mothers and fathers in the socialization of modernity are considered.     

Attitudes Toward Violence Against Women: A Cross-Nation Study

An understanding of attitudes toward violence against women is vital for effective prevention strategies. In this study we examined attitudes regarding violence against women in samples of undergraduate women and men students from four countries: India, Japan, Kuwait, and the United States. Attitudes toward sexual assault and spousal physical violence differed between men and women and across the four countries. Variations in gender differences across countries indicated that, for attitudes regarding sexual assault of women in particular, sociocultural factors may be a stronger influence than gender. Findings suggest the importance of examining differences within the larger sociocultural context of political, historical, religious, and economic influences on attitudes toward gender roles and violence against women.     

Personal factors and career adaptability in a call centre work environment: The mediating effects of professional efficacy

The study sought to assess the extent to which professional efficacy mediates the relationship between personal factors and career adaptability in a call centre work setting. The sample consisted of 409 early-career South African call centre workers (black females = 66%; age range 25 to 40). They completed measures of professional efficacy, career adaptability, sense of meaningfulness, and emotional intelligence. The results of the mediational analyses revealed that professional efficacy significantly mediate the personal meaningfulness (sense of coherence) and career adaptability relationship, but not the emotional intelligence-career adaptability relationship. Emotional intelligence independently predicted career adaptability. Call centre agents with professional efficacy are likely to be more work engaged as a result of their sense of meaningfulness and emotional intelligence.     

An item factor analysis and item response theory-based revision of the Everyday Discrimination Scale

The Everyday Discrimination Scale (EDS), a widely used measure of daily perceived discrimination, is purported to be unidimensional, to function well among African Americans, and to have adequate construct validity. Two separate studies and data sources were used to examine and cross-validate the psychometric properties of the EDS. In Study 1, an exploratory factor analysis was conducted on a sample of African American law students (N = 589), providing strong evidence of local dependence, or nuisance multidimensionality within the EDS. In Study 2, a separate nationally representative community sample (N = 3,527) was used to model the identified local dependence in an item factor analysis (i.e., bifactor model). Next, item response theory (IRT) calibrations were conducted to obtain item parameters. A five-item, revised-EDS was then tested for gender differential item functioning (in an IRT framework). Based on these analyses, a summed score to IRT-scaled score translation table is provided for the revised-EDS. Our results indicate that the revised-EDS is unidimensional, with minimal differential item functioning, and retains predictive validity consistent with the original scale.     

The Phenomenological Film Collective: Introducing a cinematic‐phenomenological research method for social advocacy filmmaking

This paper introduces the vision for the Phenomenological Film Collective ( pfcollective.com ), a research and filmmaking group which utilizes phenomenological research in the service of social advocacy filmmaking. I outline the theoretical and methodological underpinnings of developing a “cinematic‐phenomenological research method” for PFCollective in order to illuminate lived experiences of sociocultural oppression for public viewership via cinematography. The roots of cinematic phenomenology are situated within the theoretical framework of liberation psychology, which calls on psychologists to pursue research that can facilitate consciousness‐raising and social justice across society. The paper provides a methodological overview of existential‐hermeneutic phenomenological research and discusses how its research findings can be disseminated to the widespread public in artistic formats. I demonstrate how filmmaking is an appropriate aesthetic language through which to disseminate phenomenological research about lived experiences of oppression, grounding this proposition in phenomenological philosophy and liberation psychology. I outline the procedural steps for conducting cinematic‐phenomenological research to produce phenomenological films about oppressive sociocultural phenomena. The paper concludes with suggestions for academic disciplines to become more interdisciplinary in our collective pursuit for social advocacy and change.     

Performance Effects of Reward-Related Feedback on the Dimensional Change Card Sort Task

The Dimensional Change Card Sort (DCCS) is one of the most widely used measures of preschool executive function, yet relatively little is known about how altering emotional demands of the task affects DCCS performance. This study examined the effects of emotionally evocative reward-related feedback on preschool children's performance on the DCCS in a sample of 105 children aged 3.5–4.5 years. In a within-subjects design, children completed the standard DCCS and a modified version of the DCCS in which sticker rewards were gained or lost after each trial. With a reward at stake, children were more accurate but had slower reaction time on the post-switch DCCS. Another sample (N = 20) of 3.5- to 4.5-year-olds who completed the standard DCCS twice without reward showed no change in performance, indicating results are not due to practice effects. Findings demonstrate preschool children's ability to adjust their approach to the DCCS in the presence of emotionally evocative reward-related feedback by prioritizing accuracy over speed. Trial-by-trial reward-related feedback may facilitate cognitive control in early childhood.
