Implications of age of onset for delinquency risk.

Abstract: A substantial body of research suggests that age of onset is a viable discriminator of risk for chronic versus transient delinquency. Also, a mullivariate model of psychosocial variables (demographics, individual, school, and family functioning) appears likely to provide a comparatively accurate and useful discriminatory model for prediction. These two findings were applied to a normal sample of male adolescents (N=199, ages 15–18) to study the relationship of age of onset to delinquent behavior (as opposed to use of legal status to denote delinquency) and legal status. Additionally, the efficiency and improvement over chance accuracy of a multivariate model developed as part of a larger research project was tested. Results indicated that age of onset is an important and accurate discriminator of extent of subsequent delinquency. Subjects with an early age of onset reported more delinquent behavior, were more likely to be adjudicated, and showed different patterns of delinquency. A combination of demographic, individual, school, and family variables predicted age of onset.

Giving voice to emerging science and theory for lesbian, gay, and bisexual people of color.

Abstract: Lesbian, gay, and bisexual (LGB) people of color may experience multiple layers of oppression, as they often not only contend with the negative societal reactions to their sexual orientation but also may experience racial prejudice, limited economic resources, and limited acceptance within their own cultural community. Despite the range of psychosocial issues that may be encountered by this population, and the need to understand factors that promote resiliency and well-being, the empirical psychological literature has virtually ignored LGB people of color. This article provides general background regarding the empirical research needs and concerns regarding LGB people of color and introduces the articles included in this special issue. Recommendations for increasing research with LGB people of color are offered.

Note: A local-search heuristic for large set-covering problems

Abstract: In this note we describe a local-search heuristic (LSH) for large non-unicost set-covering problems (SCPs). The new heuristic is based on the simulated annealing algorithm and uses an improvement routine designed to provide low-cost solutions within a reasonable amount of CPU time. The solution costs associated with the LSH compared very favorably to the best previously published solution costs for 20 large SCPs taken from the literature. In particular, the LSH yielded new benchmark solutions for 17 of the 20 test problems. We also report that, for SCPs where column cost is correlated with column coverage, the new heuristic provides solution costs competitive with previously published results for comparable problems. © 1995 John Wiley & Sons, Inc.
