Parenting Predictors of Early-Adolescents’ Health Behaviors: Simultaneous Group Comparisons Across Sex and Ethnic Groups

The purpose of this study was to evaluate the invariance of predictive relations across early-adolescent sex and ethnic groups regarding parenting factors and externalizing and internalizing problems and victimization. Data (n = 598; 54% female) from a triethnic (Hispanic, non-Hispanic white, and non-Hispanic black) probability sample of fifth graders collected from three sites (Birmingham, AL, Houston, TX, and Los Angeles, CA) were used in the analyses. Simultaneous group structural equation modeling supported the invariance of parenting-early adolescent outcomes across sex and ethnic groups. Parental monitoring and parental norms were relatively robust predictors of early-adolescent externalizing problems and victimization, and to a lesser extent, of internalizing problems. A maternal nurturance by parental monitoring interaction was statistically significant for all outcome behaviors, indicating that higher monitoring in conjunction with higher maternal nurturance was associated with lower levels of early-adolescent problem behaviors. The findings suggest that core parenting factors such as nurturance, monitoring, and normative expectations for early adolescent problem behaviors may serve as a foundation for parenting components of multi-component intervention studies.

Detection of Inflicted Bruises by Alternate Light: Results of a Randomized Controlled Trial

Bruises are often difficult to detect on victims of violence, potentially impacting investigation and prosecution. The purpose of our randomized controlled trial was to measure the effectiveness of an alternate light source (ALS) within visible and long ultraviolet spectrums at improving bruise detection compared to white light over time. We also examined the effects of skin color, age, gender, localized fat, and injury mechanism on bruise detection. Participants included 157 healthy adults with balanced sampling across six skin color categories. Bruises were created under the controlled application of a paintball pellet and dropped weight to one upper and lower arm, respectively. Using a crossover design, both bruises were examined 21 times over 4 weeks. Ten different wavelength (350–535 nm) and filter (yellow, orange, red) combinations were used. Multilevel models were used to analyze 2903 examinations on both upper and lower arms. Results in multivariable models showed after controlling for other covariates 415 and 450 nm using a yellow filter had greater odds of detecting evidence of bruising than white light (Upper Arm: 415 nm: OR = 5.34, 95% CI: 4.35–6.56; 450 nm: OR = 4.08, 95% CI: 3.36–4.96). Under either light source, being female and having more localized fat had increased odds of detecting bruises created by the dropped weight (female: OR = 2.96, 95% CI: 2.37–3.70; fat: OR = 1.21, 95% CI: 1.09–1.34). Our results support ALS as an appropriate tool to enhance concurrent physical assessment of bruises in the presence of known history of injury. Future development and evaluation of clinical practice guidelines for ALS application are needed.     

Main drivers of human capital,learning and performance

The aim of this study was to show the relationships between the enablers for knowledge creation and human capital (HC); the effect of HC on feedback and feedforward; and the influence of these learning flows on organizational performance. To achieve this, we developed a novel theoretical model of relationships and tested this model empirically. We quantitatively test this model using data from firms in the Spanish biotechnology sector. Results show strong relationships between HC and enablers for knowledge creation (redundancy, trust, and autonomy); HC and learning flows (feedback and feedforward); and learning flows and organizational performance. The originality of this study lies in linking—theoretically, empirically, and through a novel model—independent theories of HC, learning, and knowledge creation.     

Caught in the Act: States Doing Some Things Right in Juvenile Justice

Bashing of juvenile justice systems in the United States is commonplace. We wondered if this is justified. As a product of our everyday practice and academic assessment, this article draws attention to salutary developments on several fronts, including reduced confinement, systematic assessment of child risks and needs, including use of structured decision‐making tools, evidence based services, and construction of comprehensive service plans. Our goal is to draw attention to best practices such as these that can lead to further advancements in juvenile justice systems.
