Performance architecture: The art and science of improving organizations

Performance Architecture: The Art and Science of Improving Organizations is a hands‐on guide to real‐world techniques for improving performance within the workplace. This important book explores the Human Performance Technology Landscape model that was presented in the best‐selling book Handbook of Human Performance Technology (3rd ed.). Framed by the Landscape model and supported by other proven models and tools, the book provides effective structures for anyone who needs to develop their performance improvement skills and knowledge and achieve results. Performance Architecture: The Art and Science of Improving Organizations (ISBN: 978‐0‐470‐19568‐0) is published by John Wiley & Sons and the International Society for Performance Improvement.     

Thyroid hormone levels and psychological symptoms in sexually abused adolescent girls

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.     

Fathers as sexuality educators: aspirations and realities. An Interpretative Phenomenological Analysis

Men can play a significant role in teaching their children about sexuality but fathers’ practices and perceptions in this domain remain under explored. This study presents an Interpretative Phenomenological Analysis of eight fathers’ perceptions and practices in educating their ten-year-old children about physical maturation, reproduction and relationships. A Foucauldian analysis with a focus on governmentality and biopower revealed tensions and contradictions between the fathers’ aspirations and their realities, which appeared to be underpinned by the dynamic, contradictory, shifting, plural nature of fatherhood identities. Whilst fathers wished to adhere to the cultural imperative for father–child emotional closeness, a disparity between their ambitions and their conduct emerged. Care appeared to be a deeply gendered concept for the fathers and despite their aspirations for an intimate relationship with their children, gendered norms for motherhood and fatherhood prevailed resulting in passivity in their role as sexuality educators. The study concludes by arguing that challenges to structures and subcultural contexts, which may deter fathers from fully engaging with their sons and daughters in this aspect of communication are required.     

Mindfulness training attenuates the increase in salivary cortisol concentration associated with competition in highly trained wheelchair-basketball players

This study determined the effect of 8 wk of mindfulness training (MT) on salivary cortisol (sCort) and rate of salivary Immunoglobulin-A (sIgA) secretion in wheelchair-basketball players during a competition period. The mindful group completed 8 weeks of MT in addition to training and competition. sCort and rate of sIgA secretion were measured at baseline, at 2-week intervals, the end and 2 weeks following the intervention. A significant time and group interaction was observed for sCort (F = 3.297, P = 0.040, ES = 0.191); sCort increased in the control group from MT-BL to MT-2wk (P = 0.001) and remained significantly elevated at MT-4wk (P = 0.013) and MT-6wk (P = 0.002). sCort decreased from MT-6wk to MT-8wk (P < 0.001) and concentrations were not different at MT-8wk and Post-2wk to MT-BL (P > 0.05). Mindful group sCort increased from MT-BL to MT-2wk (P = 0.042) but decreased to concentrations no different to MT-BL for the rest of the intervention period (P > 0.05). There were no group differences in rate of sIgA secretion during the intervention (P = 0.810). It was concluded that 8 weeks of MT attenuated the increase in sCort associated with the competition period.
