Hypothalamic Pituitary Adrenal Axis Functioning in Reactive and Proactive Aggression in Children

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to elicit fear (N = 33) or frustration (N = 32), or a validity check condition (N = 8). This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples for cortisol analysis were collected including 12 post-stress samples at 5-min intervals. Reactive and proactive aggression levels were assessed via the teacher-completed Aggression Behavior Teacher Checklist (Dodge and Coie, J Pers Soc Psychol, 53(6), 1146–1158, 1987). Reactive aggression significantly predicted total and peak post-stress cortisol regardless of stress modality. Proactive aggression was not a predictor of any cortisol index. Examination of pure reactive, proactive, combined, or non-aggressive children indicated that reactive aggressive children had higher cortisol reactivity than proactive and non-aggressive children. Our data suggest that while an overactive HPA-axis response to stress is associated with reactive aggression, stress induced HPA-axis variability does not seem to be related to proactive aggression.     

Forbidding Science: Some Beginning Reflections

Growing powers to manipulate human bodies and minds, not merely to heal disease but to satisfy desires, control deviant behavior, and to change human nature, make urgent questions of whether and how to regulate their use, not merely to assure safety and efficacy but also to safeguard our humanity. Oversight in democratic societies rightly belongs to the polity, not merely to self-appointed experts, scientific or ethical. Yet the task of governing the uses of dangerous knowledge is daunting, and there is little evidence that we have the will or the wisdom to do it well.

REVIEW OF SCHREIBMAN'S: THE SCIENCE AND FICTION OF AUTISM

Although the awareness of autism in the general public has increased significantly over the past 20 years, much of the widely disseminated information is not fully grounded in scientific fact. In The Science and Fiction of Autism (2005), Laura Schreibman addresses a series of debates and controversies in areas ranging from diagnostic practices and etiological theories to effective clinical practices. This book provides an overview of the field of autism that is suitable for well‐educated parents and new professionals in the field.     

Early risk pathways to physical versus relational peer aggression: The interplay of externalizing behavior and corporal punishment varies by child sex

Children who aggress against their peers may use physical or relational forms, yet little research has looked at early childhood risk factors and characteristics that uniquely predict high levels of relational versus physical aggression in preadolescence. Accordingly, the main aim of our study was to link early corporal punishment and externalizing behavior to children's physical and relational peer aggression during preadolescence and to examine how these pathways differed by sex. Participants were 193, 3‐year‐old boys (39%) and girls who were reassessed following the transition to kindergarten (5.5 years) and preadolescence (10.5 years). A series of autoregressive, cross‐lagged path analyses were conducted to examine the relationships between child externalizing problems and corporal punishment at ages 3 and 5.5 years, and their association with physical and relational aggression at age 10.5. Multiple group analysis was used to determine whether pathways differed by sex. Three developmental pathways were identified: (i) direct associations between stable childhood externalizing problems and later physical aggression; (ii) a direct pathway from early corporal punishment to preadolescent relational and physical peer aggression; and (iii) an indirect pathway from early corporal punishment to later physical aggression via continuing externalizing problems in middle childhood. Child sex moderated the nature of these pathways, as well as the direction of association between risk and outcome variables. These data advance our understanding of the etiology of distinct forms of peer aggression and highlight the potential for more efficacious prevention and intervention efforts in the early childhood years.

     

The demands and capacities model: Response to siegel

Responses to the recent critical comments of Gerald Siegel to the demands and capacities model are given. A brief history of the model's development is followed by direct explanations of its empirical support and logical development. It appears that Dr. Siegel may have referred only to one of our publications on the model. His concern about difficulties in measuring capacities is also addressed. Finally, the logic of the model is explicated and a misunderstanding regarding the use of direct therapy is clarified.     

Confounding as a problem in relating life events to health status in elderly individuals

Explored two types of confounding relevant to research relating major life events to physical illness in elderly individuals: (a) contamination of life events lists by health-related and subjective items; and (b) failure to control for illness existing prior to the life event assessment period. Community-residing elderly individuals (M = 70.4 years) completed two measures of health status in each of two waves of testing. During the second wave, participants also completed a life events list. Independent judges categorized the life events as health-related or not and further categorized non-health-related events as subjective or objective. Results indicated that life events-illness correlations were influenced by the presence of confounded items and that when illness present prior to the life event assessment period was controlled the relationship between confounded life events and illness decreased. These results underscore the importance of assessing possible sources of confounding when conducting life event illness research with elderly individuals.     

(Ad)ministering Angels: Colonial Nursing and the Extension of Empire in Africa

This essay reviews recent feminist scholarship, autobiographical narrative and fiction which explores nurses' engagement with empire in Africa and elsewhere in this century. Such literature suggests that while nursing work may have improved native health in colonized regions, it also contributed significantly to the establishment and stabilization of the racialized order of colonial rule. Of particular significance was colonial nursing's intervention into the reproductive practices of native women, resulting in the loss of local knowledges and autonomy, the disruption of complex social links and indigenous health strategies, and the expansion of markets for western capitalism.
