Understanding and Improving the Effectiveness of After-School Practice

The question driving research on after‐school programs is shifting from “do programs make a difference,” to “why are some programs effective while others are not?” This article draws on the work in this volume and related studies to suggest that there is an emerging consensus on the importance of staff‐youth interactions as a determinant of program effectiveness. The commentary recommends that future research should continue to focus on understanding and improving program practices at the point‐of‐service. In doing so, two lines of inquiry seem promising. The first involves linking measures of changes in staff‐youth interactions to changes in developmental outcomes. The second is to examine how policies or other interventions intended to improve program effectiveness affect the practices of line staff.     

Cortisol and Children’s Adjustment: The Moderating Role of Sympathetic Nervous System Activity

We examined relations among cortisol, markers of sympathetic nervous system (SNS) activity (including salivary alpha-amylase and skin conductance level), and children's adjustment. We also tested the Bauer et al. (Journal of Developmental and Behavioral Pediatrics, 23(2), 102-113, 2002) hypothesis that interactions between the SNS and cortisol would be associated with internalizing and externalizing problems. Saliva samples were obtained from 8- to 9-year-olds before and after a laboratory assessment battery, and were assayed for cortisol and alpha-amylase (sAA). Basal skin conductance level (SCL) was measured during resting conditions. Parents reported on child adjustment. Interactions between basal SNS and cortisol levels explained moderate amounts of unique variance in children's externalizing and internalizing problems. More specifically, higher basal cortisol levels were positively associated with higher internalizing and externalizing problems among children with higher SNS activity, as compared to children with lower SNS activity. Findings underscore the utility of including information about the coordination between hypothalamic-pituitary-adrenal (HPA) and SNS activity in biosocial models of atypical child development.     

Testosterone and child and adolescent adjustment: the moderating role of parent-child relationships

In a sample of established middle- and working-class families with normally developing children and adolescents ranging in age from 6 to 18 years, sons' and daughters' testosterone levels showed little direct connection to risk behavior or symptoms of depression. In contrast, testosterone's positive relation with risk behavior and negative relation with depression were conditional on the quality of parent-child relations. As parent-child relationship quality increased, testosterone-related adjustment problems were less evident. When relationship quality decreased, testosterone-linked risk-taking behavior and symptoms of depression were more in evidence. Few relations were found between parents' testosterone and child behavior. Boys' and girls' ages and stages of pubertal development were important for understanding the expression of hormone-related problem behavior in some cases but not in others.     

Creating an organizational awareness of ethical responsibility about information technology

In a time of rapid technological and social change, business organizations must help their employees develop a new appreciation of how social and ethical values are being shaped and challenged by evolving information technologies. Many ethical and social conflicts have arisen around the advanced information technology used today. The emerging technologies continue to create situations not previously encountered. There are numerous risks facing corporations involved in the use of computing technology. Leaders of organizations looking ahead to assess the impact of technological changes can try to prepare their employees for the future. This paper addresses the urgent need for individuals in corporations to become more knowledgeable about computing technologies and their impact.
