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.     

Children's objective and subjective sleep disruptions: links with afternoon cortisol levels.

OBJECTIVE: The purpose of this study was to determine possible relations between the quality and amount of children's sleep and cortisol in healthy children. DESIGN: Children's sleep was monitored with actigraphs for 7 nights. Children came to the laboratory to provide saliva samples, which were used to assess cortisol. Children reported on their sleepiness and sleep/wake problems. Sixty-four healthy children participated (M = 8.75 years; SD = .55). MAIN OUTCOME MEASURES: Self-reported sleepiness and sleep/wake problems, actigraphy-measured total sleep minutes, sleep efficiency, minutes awake after sleep onset, and sleep activity, and afternoon cortisol levels. Results: After controlling for demographic variables and child characteristics, higher levels of cortisol were related to increased subjective sleep problems and objective measures of shorter sleep duration and poorer sleep quality. CONCLUSION: These findings are of importance for understanding critical facets of children's health and well-being, and are noteworthy given the high prevalence of sleep disruptions in otherwise normally developing children in the United States.     

Peer Victimization and Aggression: Moderation by Individual Differences in Salivary Cortiol and Alpha-Amylase

This research examined whether variations in salivary measures of the hypothalamic-pituitary-adrenal axis (cortisol) and autonomic nervous system (alpha amylase [sAA]) contribute to individual differences in the association between peer victimization and aggression. Children (N = 132; M age = 9.46 years, SD = 0.33) completed a measure of peer victimization, teachers rated children’s aggression, and children’s saliva was collected prior to, and following, participation in a laboratory-based peer-oriented social challenge task. Children rated their level of frustration at the end of the task. Results revealed that victimization interacted with cortisol and sAA measured in anticipation of the task to predict aggression; the victimization × cortisol contribution to aggression was partly mediated by children’s self-reported frustration level. Victimization also was associated with heightened frustration in girls with high task-related sAA reactivity. Task-related sAA reactivity was associated with heightened aggression, but only for girls. These findings suggest that associations between peer victimization and aggression are moderated by variation in the activity of the major components of the psychobiology of stress; results are discussed in relation to theoretical models of individual differences in biological sensitivity to context.     

Towards an Embodied Poetics of the Self: Personal Renewal in Dewey and Cavell

This paper examines the different conceptions of personal renewal offered in the writings of John Dewey and Stanley Cavell. Both conceptions, I suggest, can be seen as attempting to reconcile the quest for self-realization with democratic life through a poetic, essentially Emersonian vision of the self as a continual work-in-progress. Accordingly, the kinds of selves that Dewey and Cavell seek are in the end highly compatible. Yet it seems clear too that Dewey and Cavell also stand in a somewhat different relation to the Emersonian tradition, and thus diverge in important ways as to the most preferable means of personal renewal. While Dewey tends to focus on the extensive workings of embodied habit, Cavell's ``Emersonian Perfectionism' takes a more distinctively linguistic turn. After showing the strengths and weaknesses of each approach to personal renewal, I prevail upon the need for educational environments that recognize both the discursive and nondiscursive dimensions of reconstructing the self.     

Increased testosterone-to-cortisol ratio in psychopathy

Only a few studies have examined hormones in psychopathy, and results have been mixed. It has been suggested that because hormone systems are highly interconnected, it may be important to examine multiple systems simultaneously to gain a clearer picture of how hormones work together to predispose for a certain construct. In the present study, we attempt to clarify the role of the hormones cortisol and testosterone in psychopathy by examining both hormones in a community sample of 178 adults demonstrating a wide range of psychopathy scores. Results showed that psychopathy scores were associated with an increased ratio of testosterone (baseline) to cortisol responsivity to a stressor. Psychopathy was not associated with either of these measures independently or with baseline cortisol levels. These findings suggest that these highly interconnected hormone systems may work in concert to predispose to psychopathy.
