Evaluating an integrated promotion and prevention bystander approach: Early evidence of intervention benefits and moderators.

Bullying victimization remains a pressing concern to the health and development of U.S. adolescents.

Toward a moral reckoning on structural racism: Examining structural factors, encouraging structural thinking, and supporting structural intervention.

The racial reckoning of 2020 involved the largest social movement protest in U.S. history, but support for the Black Lives Matter movement declined shortly after.

Youth-led resilience promotion during disaster recovery: A proposed framework, innovative program, and lessons learned.

Objective: Disasters, such as a school shooting or a global pandemic, harm psychological health and necessitate recovery. To complement adult-led disaster recovery and trauma-specific approaches, we propose a Youth-Led Resilience Promotion (YLRP) framework focusing on: (a) multitiered change, (b) resilience goals, (c) a promotion mindset, (d) youth strengths, (e) prosocial behaviors, and (f) capacity building through partnerships. The YLRP framework guided the development of a YLRP program in the aftermath of the Chardon High School shooting in Chardon, OH, which is detailed in a case study.

Actively caring to prevent bullying in an elementary school: Prompting and rewarding prosocial behavior.

This field study evaluated the impact of an intervention designed to prevent bullying among elementary-school students by prompting and rewarding prosocial behavior. More specifically, teachers of 404 second-, third-, fourth-, fifth-, and sixth-grade students from an elementary school in northeast Virginia asked their students to look out for other students' prosocial behaviors (termed "actively caring") and to submit their stories about actively caring. At the start of every class day, the teachers read three of these stories and recognized one story and the two associated students (i.

Intervening to promote pay-it-forward behavior: Does perceived self-motivation of the benefactor matter?

Pay-it-forward behavior reflects actively caring for people (AC4P) and the reciprocity principle. Interventions to increase the frequency of pay-it-forward behavior were evaluated. At a buffet-style dining hall, a research assistant (RA) entered the line and paid for the next person's meal.

Mixture effects of organic micropollutants present in water: towards the development of effect-based water quality trigger values for baseline toxicity.

In this study we propose for the first time an approach for the tentative derivation of effect-based water quality trigger values for an apical endpoint, the cytotoxicity measured by the bioluminescence inhibition in Vibrio fischeri. The trigger values were derived for the Australian Drinking Water Guideline and the Australian Guideline for Water Recycling as examples, but the algorithm can be adapted to any other set of guideline values. In the first step, a Quantitative Structure-Activity Relationship (QSAR) describing the 50% effect concentrations, EC50, was established using chemicals known to act according to the nonspecific mode of action of baseline toxicity.
