An interactive multiobjective programming approach to combinatorial data analysis

Combinatorial optimization problems in the social and behavioral sciences are frequently associated with a variety of alternative objective criteria. Multiobjective programming is an operations research methodology that enables the quantitative analyst to investigate tradeoffs among relevant objective criteria. In this paper, we describe an interactive procedure for multiobjective asymmetric unidimensional seriation problems. This procedure uses a dynamic-programming algorithm to partially generate the efficient set of sequences for small to medium-sized problems, and a multioperation heuristic to estimate the efficient set for larger problems. The interactive multiobjective procedure is applied to an empirical data set from the psychometric literature. We conclude with a discussion of other potential areas of application in combinatorial data analysis.Stephanie Stahl is a freelance writer and editor.

Gender-Related Effects in Emotional Responding to Resolved and Unresolved Interpersonal Conflict

The current study examines gender differences in affective responding of 58 men and 52 women to various forms of resolved and unresolved interpersonal disputes. The participants were predominantly Caucasians from middle to upper middle class socioeconomic backgrounds. Resolved disputes were perceived as less angry and more okay and happy, and unresolved disputes evoked more anger than resolved disputes did, with continued fighting evoking more anger than did lapsing into the silent treatment. Women reported feeling more angry than did men during both forms of unresolved disputes, and more happy during arguments ending with either apologies or compromises. Men perceived the actors as more sad and reported feeling more okay during arguments than did women. The results extend findings from the children's literature regarding the effect of resolution on emotional responding, and illustrate important gender differences for adults.     

IQ in childhood and the metabolic syndrome in middle age: Extended follow-up of the 1946 British Birth Cohort Study

IQ in early adulthood has been inversely associated with risk of the metabolic syndrome in midlife. We tested this association in the British 1946 birth cohort, which assessed IQ at age eight years and ascertained the metabolic syndrome at age 53 years based on modified (non-fasting blood) ATPIII criteria. Childhood IQ was inversely associated with risk of the metabolic syndrome, but this association was almost entirely mediated by educational attainment and achieved occupational social class. This may be consistent with a pattern where childhood IQ is strongly associated with outcomes that reflect neurological disorder, such as the degenerative dementias, but less so with common chronic physical diseases of ageing.     

Multiple Identity Considerations Among African American Christian Men Experiencing Same‐Sex Attraction

The authors explored the experiences of African American men who identified as Christian and experienced same‐sex attraction. Participants completed an online questionnaire addressing experiences of same‐sex attraction; meaning attributed to their attractions; the sharing of their experiences with others; and perceptions regarding the intersection of their faith, race, and sexual identity. Most respondents (61.5%) felt different from their peers for gender‐related reasons, and most (80.8%) had had homoerotic experiences during the teenage years. Over 40% of participants indicated that their primary identity was Christian, and several shared their experience sorting out attributions and meanings associated with same‐sex attraction in light of their racial and/or religious identities.     

Mexican American Mothers and Fathers’ Prenatal Attitudes and Father Prenatal Involvement: Links to Mother–Infant Interaction and Father Engagement

The present study examines the associations between Mexican American mothers’ and fathers’ pregnancy intentions, fathers’ participation in prenatal activities and mother–infant interactions and father engagement with 9 month-old infants in a nationally representative sample of 735 infants and their parents participating in the Early Childhood Longitudinal Study—Birth Cohort. After controlling for a host of variables, multiple regressions revealed that when mothers wanted the pregnancy, fathers engaged in more literacy and caregiving activities than when mothers did not want the pregnancy. When couples disagreed about wanting the pregnancy, fathers engaged in more literacy activities and showed more warmth than when they agreed. Relationship quality significantly moderated the effects of parents’ wantedness on mother–infant interactions and fathers’ engagement in literacy activities.     

The Augustinian methodological family of psychology

In his Investigations, Wittgenstein employed a quotation from Augustine to capture certain of the essential features of an incoherent conception of language that he believed was at root of many of the dominant theories of meaning of his day. It is argued in the current paper that this very same Augustinian conception of language (ACL) is the foundation of some of the most influential methodological orientations of present-day psychological science, and, as a result, these orientations suffer from a range of ACL-induced incoherences. This thesis is illustrated by way of a case study drawn from the construct validation literature.     

Caregiving Behavior Is Associated With Decreased Mortality Risk

ABSTRACT— Traditional investigations of caregiving link it to increased caregiver morbidity and mortality, but do not disentangle the effects of providing care from those of being continuously exposed to an ailing loved one with serious health problems. We explored this possible confound in a national, longitudinal survey of elderly married individuals ( N = 3,376). Results showed that spending at least 14 hr per week providing care to a spouse predicted decreased mortality for the caregiver, independently of behavioral and cognitive limitations of the care recipient (spouse), and of other demographic and health variables. These findings suggest that it may be premature to conclude that health risks for caregivers are due to providing active help. Indeed, under some circumstances, caregivers may actually benefit from providing care.     

The Utility of Genetic Counseling Prior to Offering First Trimester Screening Options

In order to evaluate the utility of genetic counseling at the time of first trimester screening in patients with no previously identified genetic concerns, we reviewed family history data for 700 women seen for genetic counseling in Utah during 2005-2006. The mean maternal age was 35 years (Range: 16–47 years). The majority of patients seen were non-Jewish Caucasians (90.8%, 634/700). A three-generation pedigree was obtained from each woman by one of two certified genetic counselors and subsequently classified as “negative” (no birth defects/genetic disorders); “positive” (birth defect or genetic condition with a minimal/low risk of recurrence; additional evaluation/genetic testing during pregnancy not indicated); or “significant” (birth defect or genetic condition with an increased risk of recurrence; additional evaluation/genetic testing during the pregnancy indicated). About 72% (501/700) of the histories were negative, 19% (134/700) were positive, and about 9% (65/700) were significant. Among patients with significant family histories, 66% (n = 43) were women less than 35 years of age. We conclude that assessing a patient’s family history at the time of first trimester serum screening is a valuable resource for pregnancy management.
