Using the Twentieth Century Reanalysis to assess climate variability for the European wind industry
We characterise the long-term variability of European near-surface wind
speeds using 142 years of data from the Twentieth Century Reanalysis (20CR),
and consider the potential of such long-baseline climate data sets for wind
energy applications. The low resolution of the 20CR would severely restrict its
use on its own for wind farm site-screening. We therefore perform a simple
statistical calibration to link it to the higher-resolution ERA-Interim data
set (ERAI), such that the adjusted 20CR data has the same wind speed
distribution at each location as ERAI during their common period. Using this
corrected 20CR data set, wind speeds and variability are characterised in terms
of the long-term mean, standard deviation, and corresponding trends. Many
regions of interest show extremely weak trends on century timescales, but
contain large multidecadal variability. Since reanalyses such as ERAI are often
used to provide the background climatology for wind farm site assessments, but
contain only a few decades of data, our results can be used as a way of
incorporating decadal-scale wind climate variability into such studies,
allowing investment risks for wind farms to be reduced.Comment: 18 pages, plus 4 page supplementary information included here as

Hearing from justice-involved, care experienced children: what are their experiences of residential care environments and regimes?
Purpose
The disproportionate representation in juvenile justice systems of children who are, or have been, in the care of the state is a major cause of concern internationally. However, the experiences of this particular group are largely absent from both policy debates and the international research base. This paper aims to correct that deficit by exploring the lived experiences of residential care, justice-involved children.
Design/methodology/approach
An interpretivist investigation of care experienced childrenās perceptions of their experiences, involving semi-structured interviews with a purposive sample of 19 children in England who were simultaneously in residential care and subject to youth justice supervision. Data were analysed using thematic content analysis.
Findings
Care-experienced children described how their experiences of residential care environments and regimes have undermined their sense of how they see themselves, now and looking to the future. Against this background of disrupted identity, they also reported stigmatising interactions with staff that leave them feeling labelled both as a generic ālooked-after childā and as a ābad kidā.
Research limitations/implications
The findings are based on the perceptions of a group of children in the criminal justice system, which, although reflecting the experiences of those with negative outcomes, may not be representative of all children in residential care.
Practical implications
The findings have implications for those responsible for the care and development of care-experienced children, as well policymakers concerned with reducing the numbers of care-experienced children in youth justice. Those responsible for the care and development of care-experienced children should consider steps to reduce how factors outlined here disrupt a childās sense of self and introduce criminogenic labelling and stigma.
Originality/value
Despite a number of studies seeking to understand why the number of care experienced children in the youth justice system is disproportionate, there is very little empirical work that seeks to understand the experiences and perceptions of children currently both in care and the criminal justice system. This paper seeks to correct this deficit, by detailing how children who are both in residential care and subject to youth justice supervision view their care experiences. The implications of this for policy, practice and further research are then explored

How Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Progresses: The Natural History of ME/CFS.
We propose a framework for understanding and interpreting the pathophysiology of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) that considers wider determinants of health and long-term temporal variation in pathophysiological features and disease phenotype throughout the natural history of the disease. As in other chronic diseases, ME/CFS evolves through different stages, from asymptomatic predisposition, progressing to a prodromal stage, and then to symptomatic disease. Disease incidence depends on genetic makeup and environment factors, the exposure to singular or repeated insults, and the nature of the host response. In people who develop ME/CFS, normal homeostatic processes in response to adverse insults may be replaced by aberrant responses leading to dysfunctional states. Thus, the predominantly neuro-immune manifestations, underlined by a hyper-metabolic state, that characterize early disease, may be followed by various processes leading to multi-systemic abnormalities and related symptoms. This abnormal state and the effects of a range of mediators such as products of oxidative and nitrosamine stress, may lead to progressive cell and metabolic dysfunction culminating in a hypometabolic state with low energy production. These processes do not seem to happen uniformly; although a spiraling of progressive inter-related and self-sustaining abnormalities may ensue, reversion to states of milder abnormalities is possible if the host is able to restate responses to improve homeostatic equilibrium. With time variation in disease presentation, no single ME/CFS case description, set of diagnostic criteria, or molecular feature is currently representative of all patients at different disease stages. While acknowledging its limitations due to the incomplete research evidence, we suggest the proposed framework may support future research design and health care interventions for people with ME/CFS
The UK ME/CFS Biobank for biomedical research on Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Multiple Sclerosis.
The UK ME/CFS Biobank was launched in August 2011 following extensive consultation with professionals and patient representatives. The bioresource aims to enhance research on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), related to pathophysiology, biomarkers and therapeutic approaches. The cohort includes 18-60 year olds, encompassing 284 clinically-confirmed ME/CFS cases, 60 neurologist-diagnosed multiple sclerosis (MS) cases, and 135 healthy individuals. The Biobank contains blood samples, aliquoted into serum, plasma, peripheral blood mononuclear cells (PBMC), red blood cells/granulocyte pellet, whole blood, and RNA (totalling 29,863 aliquots). Extensive dataset (700 clinical and socio-demographic variables/participant) enables comprehensive phenotyping. Potential reuse is conditional to ethical approval
Alterations in intestinal microbiota of children with celiac disease at time of diagnosis and on a gluten-free diet
Background & Aims:
It is not clear whether alterations in the intestinal microbiota of children with celiac disease cause the disease or are a result of disease and/or its treatment with gluten-free diet (GFD).
Methods:
We obtained 167 fecal samples from 141 children (20 with new-onset celiac disease, 45 treated with a GFD, 57 healthy children, and 19 unaffected siblings of children with celiac disease) in Glasgow, Scotland. Samples were analyzed by 16S rRNA sequencing and diet-related metabolites were measured by gas chromatography. We obtained fecal samples from 13 of the children with new-onset CD after 6 and 12 months on GFD. Relationships between microbiota with diet composition, gastrointestinal function, and biomarkers of GFD compliance were explored.
Results:
Microbiota Ī± diversity did not differ among groups. Microbial dysbiosis was not observed in children with new-onset celiac disease. In contrast, 2.8% (Bray-Curtis dissimilarity index, P=.025) and 2.5% (UniFrac distances, P=.027) of the variation in microbiota composition could be accounted for by the GFD. Between 3% to 5% of all taxa differed among all group comparisons. Eleven distinctive operational taxonomic units composed a microbe signature specific to celiac disease with high diagnostic probability. Most of the operational taxonomic units that differed between patients on GFD with new-onset celiac disease vs healthy children were associated with nutrient and food group intake (from 75% to 94%), and with biomarkers of gluten ingestion. Fecal levels of butyrate and ammonia decreased during the GFD.
Conclusions:
Although several alterations in the intestinal microbiota of children with established celiac disease appear to be effects of a GFD, there are specific bacteria that are distinct biomarkers of celiac disease. Studies are needed to determine whether these bacteria contribute to pathogenesis of celiac disease
