Searching for an environmental effect of parental alcoholism on offspring alcohol use disorder: a genetically informed study of children of alcoholics

The children-of-twins design was used to isolate a potentially causal environmental impact of having an alcoholic parent on offspring alcohol use disorder, by an examination of whether the children of alcoholics were at a higher risk for alcohol use disorders than were the children of nonalcoholic parents, even after correlated familial factors were controlled. Participants were 1,224 male and female twins from 836 twin pairs selected from the Australian Twin Registry, 2,334 of the twins' 18-39-year-old offspring, and 983 spouses of the twins. Lifetime histories of Diagnostic and Statistical Manual of Mental Disorders (4th ed.) alcohol use disorders were obtained by structured, psychiatric, telephone interviews conducted individually with each of the family members. Comparisons of the offspring of twins who were discordant for alcoholism indicated that there was no longer a statistically significant difference between the children of alcoholics and the children of nonalcoholics after genetic and family environmental factors correlated with having an alcoholic parent were controlled. The results of this study suggest that the direct causal effect of being exposed to an alcoholic parent on offspring alcohol use disorder is modest at best.     

The genetic and environmental relationship between Cloninger's dimensions of temperament and character

The purpose of this study was to determine whether Cloninger's revised 7-factor model of personality showed incremental validity over his four dimensions of temperament. A sample of 2517 Australian twins aged over 50 between 1993 and 1995 returned completed self-reported measures of Self-directedness, Cooperativeness, and Self-transcendence from Cloninger's Temperament and Character Inventory. Many of these twins had participated in a 1988 study containing Cloninger's temperament measures of Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence. Contrary to theoretical expectations, univariate analyses revealed that familial aggregation for the character dimensions could be entirely explained by additive gene action alone. Although temperament explained 26, 37 and 10% of additive genetic variance in Self-directedness, Cooperativeness and Self-transcendence, respectively, seven genetic factors were required to explain the genetic variance among the TPQ dimensions, and almost all of the non-shared environmental variance was unique to each dimension of character. Our results indicate that the inclusion of all seven dimensions in a taxonomy of personality is warranted.     

Effects of Coworker Race and Task Demand on Task‐Related Outcomes as Mediated by Evoked Affect1

Using a 2 × 2 (Coworker Race × Task Demand) design and data from 180 White women who worked in dyads with a male confederate, the present study examined the effects of coworker race (White vs. Black) and task demand (low vs. high cognitive demand) on evoked affect, task attention, task performance, task satisfaction, and the desire to work alone (as opposed to with a coworker). As expected, results showed that coworker race and task demand evoked differing levels of affect, which, in turn, influenced several other outcomes. These findings have important implications for promoting racial diversity in organizations.     

Focusing on children and youth: The role of social capital in educational outcomes in the context of immigration and diversity

Social capital matters for young people, especially for immigrant and minority youth; however what counts as social capital for young people is poorly specified. This paper reviews recent studies on the influences of parents, communities and schools; then focuses on youth social networks that begin to reveal how young people form, develop and use social capital. In light of this knowledge base, we address social and educational policy-making, making suggestions for capacity building for future policy and research. We conclude with recommendations toward a model of social capital accumulation.     

Some aspects of the psychoanalytic psychology of physicians

An earlier publication ( Halpert, 1994 ) dealt with patients' magical expectations of physicians. In this presentation, aspects of physicians' expectations of themselves as doctors will be explored. This exploration will include material from the history of medicine, a series of interviews with non-patients and the analyses of two physicians. One element in the psychology of physicians not previously appreciated that can be drawn out of this material is the role and importance of knowledge and knowing and their relation to illness, death, rescue fantasies and reality in the psychology of physians.     

Imitative violence in the real world: A reanalysis of homicide rates following championship prize fights

Recently, Phillips [Am Soc Rev, 1983; 48:560–568] reported that the homicide rate increases on the third day after heavyweight championship prize fights. The present paper reports a reanalysis of Phillips's data using more sophisticated statistical techniques and examining several theoretically important variables not discussed by Phillips or his critics. Using a conservative analysis strategy, our results suggest that the increases in homicides reported by Phillips were not a methodological artifact as suggested by Baron and Reiss [Am Soc Rev 1985; 50:347–363, 372–376]. The homicide increases only occur on the first weekend or holiday after prize fights that receive the greatest publicity.     

Cosmopolitanism,Occupancy and Political Self‐Determination

The brand of cosmopolitanism that Cécile Fabre develops in her excellent book, Cosmopolitan Peace, leaves room for qualifying groups to exercise political self‐determination. Important questions thus emerge regarding who is entitled to have a say in the group's self‐determination, questions that take on a heightened practical urgency in the wake of wars that cause massive migration. In this article, I call into question Fabre's contention that the descendants of unjust occupants necessarily acquire occupancy rights which entitle them to a say in the political self‐determination over the territory on which they currently reside.
