Could parental rules play a role in the association between short sleep and obesity in young children?
Short sleep duration is associated with obesity in young children. This study develops the hypothesis that parental rules play a role in this association. Participants were 3-year-old children and their parents, recruited at nursery schools in socioeconomically deprived and non-deprived areas of a North-East England town. Parents were interviewed to assess their use of sleep, television-viewing and dietary rules, and given diaries to document their child's sleep for 4 days/5 nights. Children were measured for height, weight, waist circumference and triceps and subscapular skinfold thicknesses. One-hundred and eight families participated (84 with complete sleep data and 96 with complete body composition data). Parental rules were significantly associated together, were associated with longer night-time sleep and were more prevalent in the non-deprived-area compared with the deprived-area group. Television-viewing and dietary rules were associated with leaner body composition. Parental rules may in part confound the association between night-time sleep duration and obesity in young children, as rules cluster together across behavioural domains and are associated with both sleep duration and body composition. This hypothesis should be tested rigorously in large representative samples
Repeated Testing in Eyewitness Memory: A Means to Improve Recall of a Negative Emotional Event
Participants viewed either a violent, arousing film or a non-violent, control version of the same film. After viewing the film, they made three successive attempts to recall details of the event. Participants who were exposed to the negative emotional event were better than control participants at recalling details of the event itself, but they were worse at recalling details that preceded or followed the violence. Both groups of participants recalled significantly more information over successive recall attempts, suggesting that memory impairment due to arousal can be alleviated by repeated testing. Repeated testing was also associated with a small but reliable increase in memory intrusions. The implications of these findings for research on hypermnesia and on the relationship between arousal and memory are discussed

Impact of dysfunctional maternal personality traits on risk of offspring depression, anxiety and self-harm at age 18 years:a population-based longitudinal study
BackgroundThe impact of underlying parental psychological vulnerability on the future mental health of offspring is not fully understood. Using a prospective cohort design, we investigated the association between dysfunctional parental personality traits and risks of offspring self-harm, depression and anxiety.MethodsThe association between dysfunctional parental personality traits (monotony avoidance, impulsivity, anger, suspicion, and detachment), measured in both mothers and fathers when offspring were age 9 years, and risk of offspring depression, anxiety and self-harm at age 18 years, was investigated in a population-based cohort (ALSPAC) from over 8000 parents and children.ResultsHigher levels of dysfunctional maternal, but not paternal, personality traits were associated with an increased risk of self-harm, depression, and anxiety in offspring. Maternal associations were best explained by the accumulation of dysfunctional traits. Associations were strongest for offspring depression: Offspring of mothers with three or more dysfunctional personality traits were 2.27 (1.45â3.54, p < 0.001) times as likely to be depressed, compared with offspring of mothers with no dysfunctional personality traits, independently of maternal depression and other variables.ConclusionsThe accumulation of dysfunctional maternal personality traits is associated with the risk of self-harm, depression, anxiety in offspring independently of maternal depression and other confounding variables. The absence of associations for equivalent paternal traits makes a genetic explanation for the findings unlikely. Further research is required to elucidate the underlying mechanism. Mothers with high levels of dysfunctional personality traits may benefit from additional support to reduce the risk of adverse psychological outcomes occurring in their offspring.</jats:sec
Evaluating megaprojects: from the âiron triangleâ to network mapping
Evaluation literature has paid relatively little attention to the specific needs of evaluating large, complex industrial and infrastructure projects, often called âmegaprojectsâ. The abundant megaproject governance literature, in turn, has largely focused on the so-called âmegaproject pathologiesâ, i.e. the chronic budget overruns, and failure of such projects to keep to timetables and deliver the expected social and economic benefits. This article draws on these two strands of literature, identifies shortcomings, and suggests potential pathways towards an improved evaluation of megaprojects. To counterbalance the current overemphasis on relatively narrowly defined accountability as the main function of megaproject evaluation, and the narrow definition of project success in megaproject evaluation, the article argues that conceptualizing megaprojects as dynamic and evolving networks would provide a useful basis for the design of an evaluation approach better able to promote learning and to address the socio economic aspects of megaprojects. A modified version of ânetwork mappingâ is suggested as a possible framework for megaproject evaluation, with the exploration of the multiple accountability relationships as a central evaluation task, designed to reconcile learning and accountability as the central evaluation functions. The article highlights the role of evaluation as an âemergentâ property of spontaneous megaproject âgoverningâ, and explores the challenges that this poses to the role of the evaluator
Inspiring and Advancing the Many-Disciplined Study of Institutional Trust
The purpose of this volume is to consider how trust research, particularly trust in institutions, might benefit from increased inter- or transdisciplinarity. In this introductory chapter, we first give some background on prior disciplinary, multidisciplinary, and interdisciplinary work relating to trust. Next, we describe how this manydisciplined volume on institutional trust emerged from the joint activities of the Nebraska Symposium on Motivation and a National Science Foundation-funded Workshop on institutional trust. This chapter describes some of the themes that emerged, while also providing an overview of the rest of the volume, which includes chapters that discuss conceptualizations, definitions, and measurement of trust; institutional trust across domains and contexts; and theoretical advances regarding the âdarkâ and âlightâ sides of institutional trust. Finally, we conclude with some thoughts about the future of and potential promises and pitfalls of trust as a focus of interdisciplinary study

Parenting Stress Undermines Mother-Child Brain-to-Brain Synchrony: A Hyperscanning Study
Synchrony refers to the coordinated interplay of behavioural and physiological signals that reflect the bi-directional attunement of one partner to the other's psychophysiological, cognitive, emotional, and behavioral state. In mother-child relationships, a synchronous pattern of interaction indicates parental sensitivity. Parenting stress has been shown to undermine mother-child behavioural synchrony. However, it has yet to be discerned whether parenting stress affects brain-to-brain synchrony during everyday joint activities. Here, we show that greater parenting stress is associated with less brain-to-brain synchrony in the medial left cluster of the prefrontal cortex when mother and child engage in a typical dyadic task of watching animation videos together. This brain region overlaps with the inferior frontal gyrus, the frontal eye field, and the dorsolateral prefrontal cortex, which are implicated in inference of mental states and social cognition. Our result demonstrates the adverse effect of parenting stress on mother-child attunement that is evident at a brain-to-brain level. Mother-child brain-to-brain asynchrony may underlie the robust association between parenting stress and poor dyadic co-regulation. We anticipate our study to form the foundation for future investigations into mechanisms by which parenting stress impairs the mother-child relationship
Maternal perinatal mental health and offspring academic achievement at age 16:the mediating role of childhood executive function
Background: Elucidating risk pathways for under-achieving at school can inform strategies to reduce the number of
adolescents leaving school without passing grades in core subjects. Maternal depression can compromise the quality
of parental care and is associated with multiple negative child outcomes. However, only a few small studies have
investigated the association between perinatal maternal depression and poor academic achievement in adolescence.
The pathways to explain the risks are also unclear. Method: Prospective observational data from 5,801 parents and
adolescents taking part in a large UK population cohort (Avon-Longitudinal-Study-of-Parents-and-Children) were
used to test associations between maternal and paternal depression and anxiety in the perinatal period, executive
function (EF) at age 8, and academic achievement at the end of compulsory school at age 16. Results: Adolescents of
postnatally depressed mothers were 1.5 times (1.19, 1.94, p = .001) as likely as adolescents of nondepressed
mothers to fail to achieve a âpassâ grade in math; antenatal anxiety was also an independent predictor of poor math.
Disruption in different components of EF explained small but significant proportions of these associations:
attentional control explained 16% (4%, 27%, p < .001) of the association with postnatal depression, and working
memory explained 17% (13%, 30%, p = .003) of the association with antenatal anxiety. A similar pattern was seen for
language grades, but associations were confounded by maternal education. There was no evidence that paternal
factors were independently associated with impaired child EF or adolescent exams. Conclusion: Maternal postnatal
depression and antenatal anxiety are risk factors for adolescents underachieving in math. Preventing, identifying,
and treating maternal mental health in the perinatal period could, therefore, potentially increase adolescentsâ
academic achievement. Different aspects of EF partially mediated these associations. Further work is needed, but if
these pathways are causal, improving EF could reduce underachievement in math
