A systematic review of the effect of dietary exposure that could be achieved through normal dietary intake on learning and performance of school-aged children of relevance to UK schools

The aim of the present review was to perform a systematic in-depth review of the best evidence from controlled trial studies that have investigated the effects of nutrition, diet and dietary change on learning, education and performance in school-aged children (4-18 years) from the UK and other developed countries. The twenty-nine studies identified for the review examined the effects of breakfast consumption, sugar intake, fish oil and vitamin supplementation and 'good diets'. In summary, the studies included in the present review suggest there is insufficient evidence to identify any effect of nutrition, diet and dietary change on learning, education or performance of school-aged children from the developed world. However, there is emerging evidence for the effects of certain fatty acids which appear to be a function of dose and time. Further research is required in settings of relevance to the UK and must be of high quality, representative of all populations, undertaken for longer durations and use universal validated measures of educational attainment. However, challenges in terms of interpreting the results of such studies within the context of factors such as family and community context, poverty, disease and the rate of individual maturation and neurodevelopment will remain. Whilst the importance of diet in educational attainment remains under investigation, the evidence for promotion of lower-fat, -salt and -sugar diets, high in fruits, vegetables and complex carbohydrates, as well as promotion of physical activity remains unequivocal in terms of health outcomes for all schoolchildren.</p

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

SoundSocket [power line audio signal transmission]

SoundSocket, an innovative product from Electraudio, is an audio system which utilizes the concept of power line communication to transmit an audio signal, avoiding the need to rely on wireless technology or external wiring and the cumbersome setup associated with it. With SoundSocket, the user simply plugs the transmitter unit into a wall outlet and may utilize another outlet as both the audio and power source for the receiver unit. SoundSocket is a robust and reliable product that delivers CD quality audio

ATMOSPHERIC CLIMATE CONTROL OF DIRECTIONAL WAVES IN THE UNITED KINGDOM AND IRELAND

International audienceUnderstanding multi-annual to decadal atmospheric climate controls on winter-wave climate is critical for coastal vulnerability assessment and future development of 'season ahead' forecasting of coastal risk. We examine the relationships between winter-average climate indices (NAO and WEPA) and directional wave power at 63 inshore locations throughout the United Kingdom and Ireland (UK&I). Analysis of hindcast wave data between 1980-2017 illustrate the extent of directional bi-modality, with 67% of inshore sites displaying directionally multimodal wave climates. Analysis of directional modes as a function of climatic indices illustrated the control exerted by NAO/WEPA on directional balance of inshore winter wave climate. Along Channel and southern North Sea coasts +WEPA significantly explains winter-averaged wave power for southwesterly wave directional modes (r = 0.58-0.77) and-NAO significantly explains variability in all easterly wave modes (r = 0.6-0.76), providing a mechanism for which 'season ahead' inshore wave climate forecasting and rotational beach response can be based

Turning away from the public sector in children's out-of-home care: An English experiment

This paper reports on the evaluation of an English experiment which, for the first time, moved statutory social work support for children and young people in out-of-home care from the public to the private or independent sector. Five social work practices (SWPs), independent or semi-independent of local government, were established and evaluated using a matched control design with integrated process evaluation. Social work teams in the public sector, selected to correspond to key characteristics of the SWP sites, provided control sites. While most SWPs were perceived to be accessible and user-friendly organizations, children's and young people's accounts showed no differences between pilots and control sites in terms of workers' accessibility and responsiveness. Perceptions of SWP staff's decision-making were mixed. SWP staff reported spending more time in direct face-to-face work with children and families but this was attributed to reduced caseload size and a tight remit which excluded child protection work rather than to decreased bureaucracy. SWP staff morale was generally found to be high in terms of depersonalization and social support, reflecting an emphasis on staff supervision in these organizations. However, this was offset by slightly higher job insecurity which reflected the precariousness of employment in the independent as opposed to state sector. Staff retention varied between the SWPs, but although children and young people in the pilots were more likely to retain their key worker than those in control sites, they experienced disruption in the move into SWPs and back to public services when SWP contracts were not renewed. While some SWPs succeeded in reducing placement change rates for children and young people, a policy of switching placement providers to achieve flexibility and savings increased placement change rates in some SWPs. SWPs did not achieve financial independence from the local authority commissioners with only one assuming full responsibility for managing the placement budget. Payment by results was not used consistently. None of the commissioners interviewed considered that the SWP model had resulted in savings. The study highlighted the interdependence of public and private sectors. As small organizations, most of the SWPs succeeded in offering an accessible and personalized service, and public services should consider reorganizing to achieve similar outcomes. However, this evaluation found that contracted-out organizations struggled to provide children in out-of home care with the consistency and continuity they require
