Talking about the silent fear: adolescents' experiences of violence in an urban high-rise community

The self-reported violent experiences of adolescents living in a public-subsidized urban high-rise building were examined. This effort was part of an interdisciplinary, community-university collaboration program called the HOME (High-rise On-site Multifamily Environments) Family Support Project. A survey of violent experiences and a one-on-one structured interview were conducted with 20 adolescent residents. Results of the quantitative and qualitative analyses revealed high degrees of exposure to violence among these adolescents, concerns for their personal safety, as well as insights into what they believe adults could and should be doing to address increasing levels of community violence. The implications of these results for conducting ecologically valid research on sensitive issues with adolescents and for family support program planning are discussed.     

Iterated Belief Revision and Conditional Logic

In this paper we propose a conditional logic called IBC to represent iterated belief revision systems. We propose a set of postulates for iterated revision which are a small variant of Darwiche and Pearl's ones. The conditional logic IBC has a standard semantics in terms of selection function models and provides a natural representation of epistemic states. We establish a correspondence between iterated belief revision systems and IBC-models. Our representation theorem does not entail Gärdenfors' Triviality Result.     

Rebellious teens? Genetic and environmental influences on the social attitudes of adolescents

Genetic and environmental influences in social attitudes were investigated in adopted and nonadopted children (N = 654) and their biological and adoptive relatives in the Colorado Adoption Project. Conservatism and religious attitudes were measured in the children annually from ages 12 to 15 and in the parents during the 12-year-old visit. Multivariate genetic model fitting indicated that both conservatism and religious attitudes are strongly influenced by shared-family environmental factors throughout adolescence. In contrast to previous findings from twin studies, which suggest that genetic influence on social attitudes does not emerge until adulthood, the present study detected significant genetic influence in conservatism as early as age 12. There was no evidence of genetic influence, however, on religious attitudes during adolescence.

Group exercise reduces depression in obese women without weight loss

Given participation in a 6-mo. exercise and relaxation training 8 obese women showed significant change in scores on the Beck Depression Inventory over the 6-mo. interval, but not on Body Mass Index or Medical Outcome Study Short-Form-36.     

Replacing the Patient: The Fiction of Prosthetics in Medical Practice

The invention of computer simulations used for practicing surgical maneuvers in a video game-like format has an ancestry in the artificial limbs of history and is reflected, grotesquely, in Edgar Allan Poe's short story, "The Man That Was Used Up" (1850). The nineteenth century worked to ensure that the incomplete body did indeed retain a sense of self by creating prostheses to mimic corporeal wholeness. Our present-day technology seems intent on doing precisely the opposite, deliberately fragmenting the body and challenging our understanding of the body and the prosthetic.     

Convergence and predictive validity in measures of optimism and pessimism: Sequential studies

Optimism and pessimism are personality variables that have repeatedly been shown to affect health, job performance, and social relationships. Various instruments purport to measure these dispositions that differ substantially in their theoretical and measurement models. While research has examined relations between subsets of these measures, their unique predictive ability has been neglected. Three sequential studies evaluated the interrelation and predictive ability of the three most utilized instruments, the Life Orientation Test (LOT), the O/P Instrument (OPI) and variants of the Attributional Style Questionnaire (ASQ). Consistent with expectations, measures sharing a future-expectancy component (LOT and OPI) were moderately related and most predictive of health, depression, and coping. ASQ measures were modestly related to the LOT and OPI and offered less consistent predictions.
