Realism Despite Cognitive Antireductionism

Building on previous work, I continue the arguments for scientific realism in the presence of a natural level structure of science. That structure results from a cognitive antireductionism that calls for the retention of mature theories even though they have been “superseded”. The level structure is based on “scientific truth” characterized by a theory's validity domain and the confirming empirical data. Reductionism (including fundamentalism) fails cognitively because of qualitative differences in the ontology and semantics of successive theories. This cognitive failure exists in spite of the mathematical success of theory reduction. The claim for scientific realism is strongly based on theory coherence between theories on adjacent levels. Level coherence consists of mathematical relations between levels, as well as of reductive explanations. The latter refers to questions that can be posed (but not answered) on a superseded level, but which can be answered (explained) on the superseding level. In view of the pluralism generated by cognitive antireductionism, theory coherence is claimed to be so compelling that it provides strong epistemic justification for a pluralistic scientific realism.     

Relationship of social support and social burden to repeated breast cancer screening in the women's health initiative.

Direct and interactive effects of social support, social burden (caregiving, negative life events, and social strain), education, and income on repeated use of breast cancer screening among a large (N=55,278), national sample of postmenopausal women participating in the Women's Health Initiative observational study were examined. Repeated screening decreased as emotional/informational support and positive social interactions decreased (ps<.01). Repeated mammography decreased with frequent caregiving (p<.01). Less social strain reduced the frequency of repeated breast self-examinations (BSEs; ps<.01), but frequent caregiving and more negative life events increased repeated use of BSE (ps<.01). Interactive effects suggested that emotional/informational but not tangible support is associated with repeated mammography and clinical breast examinations (ps<.01) and may be particularly important among low-income older women, especially those burdened by caregiving.     

Beyond the “Critical” Curtain: Community‐based Service Learning in an African Context

Abstract. A case of community‐based service learning in the School of Theology at the University of Natal, Pietermaritzburg, South Africa is analyzed for what it means to teach biblical studies in an African context where biblical scholarship is partially constituted by ordinary African readers of the Bible and where context is a central pedagogical concept. Reflecting on a series of experiments over the past ten years in two second‐year University level modules, the article analyzes the contours of a partnership between the academy and local communities of the poor, working‐class, and marginalized through community‐based service learning. This partnership provides a form of contextualization that enables students to integrate the forms of engagement with the Bible they bring to their formal theological studies and the forms of critical distance that characterize the discipline of biblical studies.     

Women accused of sex offenses: a gender-based comparison

Sexual offenses committed by women are likely underestimated and under-reported. This exploratory study compares and contrasts women accused of sexual offenses and their male counterparts. Data were retrospectively compiled on all alleged female and age-matched male sex offenders who were referred for psychiatric evaluation to a large Midwestern city's court psychiatric clinic over a six-year period. Data were abstracted regarding their crimes, charges, demographics, social history, medical history, legal history, violence history, substance use, sexual history, psychiatric history and their victims. Like the men, women were most frequently referred for sexual predator classification evaluations. Ages ranged from 19 to 62 years, and the majority had children. Most had prior arrests. One-third had a past history of psychiatric hospitalization, and most were given a non-paraphilic psychiatric diagnosis. The majority of the women reported past histories of sexual or physical victimization. While there were many similarities between female and male sex offenders in this psychiatric sample, women more frequently had victims of both genders.     

Memory in traumatic brain injury: The effects of injury severity and effort on the Wechsler Memory Scale‐III

This study examined the effects of traumatic brain injury (TBI) on Wechsler Memory Scale‐III (WMS‐III) performance. Since poor effort potentially contaminates results, effort was explicitly assessed and controlled using two well‐validated cognitive validity indicators, the Portland Digit Recognition Test (PDRT) and Reliable Digit Span (RDS). Participants were 44 mild TBI patients with good effort, 48 mild TBI patients with poor effort, and 40 moderate–severe TBI patients with good effort. A dose–response relationship between injury severity and WMS‐III performance was demonstrated. Effect size calculations showed that the good effort mild TBI patients did not differ from normal (average Cohen's d= 0.07) while moderate–severe TBI had a moderate effect on WMS‐III scores (average Cohen's d=?0.52). Consistent with previous literature, the moderate–severe TBI group scored the lowest on WMS‐III Visual indices. Effort had a larger effect than injury severity on WMS‐III scores (average Cohen's d=?1.27). Clinical implications of these findings are discussed.     

The Army National Guard in OIF/OEF: Relationships among combat exposure,postdeployment stressors,social support,and risk behaviors

With the continued operations in Iraq and Afghanistan, studies of the prevalence of posttraumatic stress disorder and related symptoms are now common. However, lacking is how these symptoms relate to precipitating conditions and the mitigating effects of social support on these symptoms. This is particularly relevant for reserve military personnel, who have been shown to be greater at-risk for postdeployment problems. The present study examined questionnaire data obtained from Army National Guard (ARNG) units immediately after their return from deployment to Iraq and Afghanistan during 2010 (N = 4329 soldiers in 50 units). Findings showed few soldiers displayed risk behaviors (i.e., daily alcohol use, use of illicit drugs, suicide thoughts, and physically threatening others) during and after deployment. Those most likely to have more postdeployment risk behaviors were also those who showed more risk behaviors during deployment. A substantial percentage of soldiers reported combat exposure, postdeployment negative emotions, and postdeployment loss of a personal relationship. These reported outcomes were all related to increased risk behaviors after deployment. The buffering effect of social support on postdeployment risk behaviors was equally evident when data were examined individually and when grouped by unit memberships. Implications of findings for future research, practice, and policies are discussed.     

A guide for the estimation of gender and sexual orientation effects in dyadic data: an actor-partner interdependence model approach

The study of gender differences is a pervasive topic in relationship science. However, there are several neglected issues in this area that require special care and attention. First, there is not just one gender effect but rather three gender effects: gender of the respondent, gender of the partner, and the gender of respondent by gender of the partner interaction. To separate these three effects, the dyadic research design should ideally have three different types of dyads: male-female, male-male, and female-female. Second, the analysis of gender differences in relational studies could benefit from the application of recent advances in the analysis of dyadic data, most notably the Actor-Partner Interdependence Model. Third, relationship researchers need to consider the confounding, mediating, and moderating effects of demographic variables. We use the American Couples (Blumstein & Schwartz, 1983) data set to illustrate these points.     

Measuring individualism and collectivism: The importance of considering differential components,reference groups,and measurement invariance

A new instrument of individualism and collectivism (I/C) was developed and three key issues in I/C measurement were addressed: differentiating components of I/C, understanding the impact of reference groups, and testing of measurement invariance. Three components of I/C were assessed in China and the U.S.: independence, competitiveness, and uniqueness for individualism; considering of one’s decisions on others, sharing of positive outcomes, and sharing of negative outcomes for collectivism. Collectivism was measured with respect to parents, friends, and general others. Results indicate that Chinese participants are less unique but more independent and competitive than their counterparts in the U.S. The expected cultural difference is found for parent collectivism across all three components and for sharing negative outcome with respect to all three reference groups. These results suggest that individualism is a multidimensional construct, whereas the dimensionality of collectivism appears to be a function of social distance. Measurement invariance was tested at configural, factor loading, and intercept levels for all components of I/C.     

Two‐Step Testing in Employee Selection: Is score inflation a problem?

Unproctored Internet testing in employee selection has become increasingly popular over the past few years. However, there is a concern that cheating during unproctored administrations may influence the test results in terms of score inflation. The current research attempts to determine the extent of cheating on an unproctored Internet test of perceptual speed by analyzing data from a parallel version of the test administered in a proctored setting. Among a sample of 856 job applicants from nine European countries, there was no evidence that cheating occurred. In fact, evidence of an effect operating in the opposite direction was obtained. These results indicate that the use of unproctored Internet testing is appropriate for this type of test.
