Can sample-specific simulations help detect low base-rate taxonicity?

The authors examined the role of the sample-specific simulations (SSS; A. M. Ruscio & J. Ruscio, 2002; J. Ruscio & A. M. Ruscio, 2004) procedure in detecting low base-rate taxa that might otherwise prove elusive. The procedure preserved key distributional characteristics for moderate to high base-rate taxa, but it performed inadequately for low base-rate taxa, with low to moderate nuisance covariance, decreasing indicator validity, and increasing average nuisance covariance. Visual inspection of the curves produced by the SSS procedure, combined with the expectation that the inchworm test should produce a clear peak for low base-rate taxonic samples, led to inappropriate conclusions about the suitability of data. The authors speculate that examination of low base-rate taxa using SSS may require other algorithms for generating comparison distributions, consideration of the shape of the whole curve, and/or relaxation of the expectation that a clear peak will emerge with the inchworm test.     

A family-focused randomized controlled trial to prevent adolescent alcohol and tobacco use: The moderating roles of positive parenting and adolescent gender

Four years of longitudinal data from 2,153 families with a 5th- or 6th-grade preadolescent participating in a family-focused pediatric primary-care-based prevention program were used to examine whether prevention effects were moderated by positive parenting and/or adolescent gender. Alcohol and tobacco use, internalizing problems, and externalizing problems were examined. Although findings revealed no main effect of the prevention program, positive parenting and adolescent gender were moderators of internalizing problems and adolescent gender was a moderator of externalizing problems. Clinical implications and future directions for research are discussed.     

The role of a lifetime history of oppositional defiant and conduct disorders in adults with ADHD: implications for clinical practice

IntroductionAttention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) are frequently co-occurring disorders in children and adolescents. However, their clinical status among adults is still under discussion. This study analyzes how the current clinical presentation of adult ADHD might be influenced by a lifetime history of CD and ODD. METHODS: We compared three groups of patients: ADHD without history of CD/ODD (n = 178), ADHD + history of ODD (n = 184), and ADHD + history of CD (n = 96). RESULTS: A history of CD (and to a lower extent ODD) is associated with a more severe and externalizing profile.ConclusionPast CD and ODD entail a significant negative mental health impact on persistent ADHD, reinforcing the importance of actively assessing the developmental history of adult ADHD patients.     

Knowledge-sharing intention in a virtual community: a study of participants in the Chinese Wikipedia

This study proposes a model for evaluating virtual community members' knowledge-sharing intention toward Chinese Wikipedia. The results of this study reveal that knowledge-sharing intention is influenced directly by attitude, subjective norms, and perceived behavioral control, whereas anticipated reciprocal relationships and enjoying helping are positively related to attitude; sense of self-worth and peer influences are positively related to subjective norms; and self-efficacy and resource-facilitating conditions are positively related to perceived behavioral control on knowledge sharing.     

Patterns of Sexuality Communication Between Preadolescents and Their Mothers and Fathers

The purpose of the current study was to examine communication about sexual topics between preadolescents and their mothers and fathers. Participants were 135 African-American mothers, fathers, and their 9- to 12-year-old offspring. Each member of the triad completed a 10-item measure of communication about risk factors for sexual activity, sexual communication, and sexual risk prevention. A majority of parents and their preadolescents reported communication had occurred about most topics. Mothers and fathers were equally likely to communicate with sons whereas mothers were more likely to communicate with daughters than were fathers. Based on the study results, preadolescence may be the optimal time for parents to provide sexual risk prevention messages to their children before sexual behaviors are initiated.     

Acceptability of racial microaggressions among Asian American college students: internalized model minority myth,individualism, and social conscience as correlates

ABSTRACT

How much someone finds a racial microaggression to be acceptable can vary. We focus on the acceptability of racial microaggressions among Asian American college students, in relation to cultural and religious variables. We predicted that internalized model minority stereotype and individualism will be associated with being more accepting of microaggressions. We predicted that social conscience, or the belief that the church should be active in social justice, will be associated with being less accepting of microaggressions. Results based on 102 Asian American students indicated that vertical individualism predicts greater acceptance of microaggressions, and results based on 77 Christian individuals out of the 102 participants indicated that social conscience predicts less acceptance of microaggressions. Excessive individualism may lead one to ignore the impact of racism and have a greater tolerance for microaggressions, whereas social conscience may support participation in social justice efforts, which may lead to a greater awareness of microaggressions.
