Cortisol Stress Response Variability in Early Adolescence: Attachment,Affect and Sex

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.     

Measuring and managing ‘state fragility’: the production of statistics by the World Bank,Timor-Leste and the g7+

Indicators are currently being widely used in international policy making to substantiate analyses and justify decisions on the basis of their alleged scientific objectivity. This article analyses the role of indicators and statistics in the labelling and managing of ‘fragile states’, examining the powerful consequences of these classifications but also discussing the untraceable nature of numbers and the difficulties in attributing ownership of numerical claims and assigning responsibility for their many unforeseen impacts. Focusing on the education sector in Timor-Leste and on the World Bank’s Country Policy and Institutional Assessment (cpia) programme, the article shows how accountability and ownership are negotiated within the context of the g7+ group of self-labelled ‘fragile states’, encouraging an examination of the power relations involved.     

‘Nature takes no notice of morality’: singleness and married love in interwar Britain1

This article draws attention to the dominance of marriage during the twentieth century and the strain this institution was, and still is, under. This is achieved by focusing upon the single as a problematic category in the context of interwar Britain through an examination of the writings of Marie Carmichael Stopes, one of the leading experts on marriage, and her single correspondents. There are clear contradictions in Stopes's writings, which she was unable to acknowledge, between sex as a normal healthy appetite which it could be dangerous to suppress and the denial of a sex life to the single. These are shown to have had the potential to destabilise marriage as the only site of legitimate reproduction and sexual relations. Examining the differences between her advice to single men and women also exposes the gender divide in relation to the concept of sublimation and the difficulties inherent in the concept of substitute mother as a stable and coherent identity for the single woman. The article concludes by making links between the position of single men and women in the early twentieth century and today.     

Whistleblower protection for nurses and other health care professionals

Because most employees in the United States, including health care professionals, are employed "at will" (which means their employment can be terminated for any reason or no reason, as long as the reason isn't illegal), retaliatory actions by employers toward employees who speak out (i.e., blow the whistle) are not uncommon. Additionally, the law protecting whistleblowing employees varies greatly depending on the state where the employee works or if he or she works for the federal government. This article examines when and under what conditions a nurse or other health care professional may be protected from having an adverse employment action taken against him or her for reporting such issues as patient safety violations or health care fraud. The authors offer issues a nurse or other health care professional should consider before making the decision to blow the whistle. Finally, the authors also discuss the remedies such as reinstatement, back pay, or other compensatory mechanisms that may be available to employees terminated for reporting wrongdoing.     

The use of linear dichroism in forensic fibre examinations — Part 6. Validation and practical aspects of MSP-PPL

This paper summarizes the results of previous work on the microscopic observation of linear dichroism found in dyed fibres (polyesters, polyamides, wool, silk, cotton, viscose, acrylics and acetates) and in pigmented fibres as well as the measurements on these fibre classes using microspectrophotometry with plane polarized light (MSP-PPL). The validation of this method is discussed and a practical tool is proposed for comparing fibre traces with control fibres. The limitations and strengths of this method are also revised.     

Experimental Study of Bite Mark Injuries by Digital Analysis

Abstract: This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the “injuries,” using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer‐aided programs in this study of bite marks.
