Examination of the neural substrates activated in memories of experiences with resonant and dissonant leaders

Given the relevance of leadership in organizational life, we designed an exploratory study to assess the neural mechanisms involved in memories of interactions with resonant and dissonant leaders (a follower-centric study). Subjects in advanced professional roles were asked about previous incidents with both types of leaders, and functional magnetic resonance imaging (fMRI) scans were then conducted with cues developed from these recollections. Recalling experiences with resonant leaders activated neural areas such as the bilateral insula, right inferior parietal lobe, and left superior temporal gyrus; regions associated with the mirror neuron system, default mode or social network, and positive affect. Recalling experiences with dissonant leaders negatively activated the right anterior cingulate cortex and activated the right inferior frontal gyrus, bilateral posterior region of the inferior frontal gyrus, and bilateral inferior frontal gyrus/insula; regions associated with the mirror neuron system and related to avoidance, narrowed attention, decreased compassion, and negative emotions.     

Protective factors among families with children at risk of maltreatment: Follow up to early school years

The purpose of this study is to explore both risk and protective factors of child maltreatment among at risk elementary school children. This study used data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN), following a cohort of 405 children from age 4 to age 8. Multivariate logistic regression revealed that children attending preschool irregularly (OR = 2.98; 95% CI: 1.08-8.26), families with a high level of life events (OR = 2.68; 95% CI: 1.12-6.41), and mothers with a history of childhood maltreatment (OR = 2.26; 95% CI: 1.07-4.76) were more likely to have a child maltreatment report. In contrast, mothers who were married (OR = 0.19; 95% CI: 0.06-0.64), mothers who attained 12 or more years of education (OR = 0.09; 95% CI: 0.02-0.34), and family with high level of social support (OR = 0.29; 95% CI: 0.11-0.80) were less likely to have a child maltreatment report. For mothers who had not graduated from high school, adequate social support reduced the risk of child maltreatment by a factor of two. The provision of adequate social support should be incorporated into child maltreatment prevention programs, particularly those targeting at risk families.     

Australian women's experiences of living with gestational diabetes

PurposeThe purpose of this study was to describe Australian women's reflections on the experience of having a pregnancy affected by GDM.MethodsParticipants were women aged ≥18 years, diagnosed with GDM ≤3 years previously and registered with the National Diabetes Services Scheme. Data was collected from a cross-sectional written postal survey which included the opportunity for women to document their experiences of living with GDM. Thematic framework analysis was undertaken to determine underlying themes.ResultsOf 4098 invited eligible women, 1372 consented to participate. Of these, 393 provided feedback on their experiences of living with GDM. Eight key themes emerged from the data (1) shock, fear and anxiety (8.9%), (2) uncertainty and scepticism (9.4%), (3) an opportunity to improve one's health (9.6%), (4) adapting to life with GDM (11.6%), (5) the need for support (17.2%), (6) better awareness (3.5%), (7) abandoned (14.9%), (8) staying healthy and preventing diabetes (13.7%). Women taking insulin were more likely to experience shock, fear or anxiety (p = 0.001) and there was a trend towards women who spoke another language also being more likely to report this experience (p = 0.061). Those diagnosed with GDM in a previous pregnancy (p = 0.034) and younger women (p = 0.054) were less likely to view the diagnosis as an opportunity to improve their health.ConclusionsThis study provides an insight into the experience of the pregnant woman diagnosed with GDM. It emphasises the importance of health professional support and provides insight into the challenges and opportunities for future diabetes risk reduction.     

Correction for bias in maximum likelihood estimators of in a right–censored normal distribution

It is assumed that the logs of the time to failure in a life test follow a normal distribution. If the test is terminated after r of a sample of n items fail, the test is said to be censored. If the sample size is small and censoring severe, the usual maximum likelihood estimator of a is downwardly biased. Monte Carlo techniques and regression analysis were used to develop an empirical correction factor. Applying the correction factor to the maximum likelihood estimator yields an unbiased estimate of σ.     

Locked into gambling: anticipatory regret as a motivator for playing the National Lottery

Four hundred and eighty-five people were asked about their intentions to play the National Lottery in England a week prior to the introduction of a new midweek draw. We predicted that those people who played the Saturday game with a regular set of numbers would be more inclined to play the new midweek game than those who had not established a routine of using the same set of numbers. We further predicted that their motivation to play would derive from a feeling of 'anticipatory regret'—a sense that they would find it intolerable to discover their regular numbers had been drawn when they hadn't purchased a ticket. Results supported both of these predictions, and an interpretation of the data is given in terms of the circumstances most likely to trigger such counterfactual reasoning.     

Family Grief and Mental Health: A Systemic,Contextual and Compassionate Analysis

Although not always named, grief is central to the experience of mental illness — for people diagnosed, their families and their friends. Yet grief is almost absent from the literature and practice of mainstream psychiatry. This curious fact led to the writing of this article by two workers and a carer, with editorial and political advice from a consumer, as a small step in the direction of integrating perspectives of workers, carers and consumers. It examines the nature of grief associated with mental illness, its impact on family members, and why mainstream mental health services do not directly address it, with suggestions for some therapeutic ways to conceptualise and work with it.
