The Impact of Interactive Shared Book Reading on Children's Language Skills: A Randomized Controlled Trial.

Purpose Research has indicated that interactive shared book reading can support a wide range of early language skills and that children who are read to regularly in the early years learn language faster, enter school with a larger vocabulary, and become more successful readers at school. Despite the large volume of research suggesting interactive shared reading is beneficial for language development, two fundamental issues remain outstanding: whether shared book reading interventions are equally effective (a) for children from all socioeconomic backgrounds and (b) for a range of language skills. Method To address these issues, we conducted a randomized controlled trial to investigate the effects of two 6-week interactive shared reading interventions on a range of language skills in children across the socioeconomic spectrum. One hundred and fifty children aged between 2;6 and 3;0 (years;months) were randomly assigned to one of three conditions: a pause reading, a dialogic reading, or an active shared reading control condition. Results The findings indicated that the interventions were effective at changing caregiver reading behaviors. However, the interventions did not boost children's language skills over and above the effect of an active reading control condition. There were also no effects of socioeconomic status. Conclusion This randomized controlled trial showed that caregivers from all socioeconomic backgrounds successfully adopted an interactive shared reading style. However, while the interventions were effective at increasing caregivers' use of interactive shared book reading behaviors, this did not have a significant impact on the children's language skills. The findings are discussed in terms of practical implications and future research. Supplemental Material https://doi.org/10.23641/asha.12420539

The Winter Camp of the Viking Great Army, AD 872–3, Torksey, Lincolnshire

This paper presents the results of a multidisciplinary project that has revealed the location, extent and character of the winter camp of the Viking Great Army at Torksey, Lincolnshire, of AD 872–3. The camp lay within a naturally defended area of higher ground, partially surrounded by marshes and bordered by the River Trent on its western side. It is considerably larger than the Viking camp of 873–4 previously excavated at Repton, Derbyshire, and lacks the earthwork defences identified there. Several thousand individuals overwintered in the camp, including warriors, craftworkers and merchants. An exceptionally large and rich metalwork assemblage was deposited during the Great Army’s overwintering, and metal processing and trading was undertaken. There is no evidence for a pre-existing Anglo-Saxon trading site here; the site appears to have been chosen for its strategic location and its access to resources. In the wake of the overwintering, Torksey developed as an important Anglo-Saxon borough with a major wheel-thrown pottery industry and multiple churches and cemeteries. The Torksey evidence allows for a radical reappraisal of the character of Viking winter camps, and the legacy of the Viking Great Army for Anglo-Saxon England

Developing a model of mental health self-care support for children and young people through an integrated evaluation of available types of provision involving systematic review, meta-analysis and case study

Background The mental health of children and young people (CYP) is a major UK public health concern. Recent policy reviews have identified that service provision for CYP with mental health needs is not as effective, responsive, accessible or child-centred as it could be. Following on from a previous National Institute for Health Research (NIHR) study into self-care support for CYP with long-term physical health needs, this study explored self-care support’s potential in CYP’s mental health. Objectives To identify and evaluate the types of mental health self-care support used by, and available to, CYP and their parents, and to establish how such support interfaces with statutory and non-statutory service provision. Design Two inter-related systematic literature reviews (an effectiveness review with meta-analysis and a perceptions review), together with a service mapping exercise and case study. Setting Global (systematic reviews); England and Wales (mapping exercise and case study). Participants (case study) Fifty-two individuals (17 CYP, 16 family members and 19 staff) were interviewed across six sites. Main outcome measures (meta-analysis) A measure of CYP’s mental health symptomatology. Data sources (literature reviews) MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, All Evidence-Based Medicine (EBM) Reviews, Applied Social Sciences Index and Abstracts (ASSIA) and Education Resources Information Center (ERIC). Review methods Titles and abstracts of papers were screened for relevance then grouped into studies. Two independent reviewers extracted data from studies meeting the inclusion criteria. A descriptive analysis and meta-analysis were conducted for the effectiveness review; descriptive analyses were conducted for the perceptions review. These analyses were integrated to elicit a mixed-methods review. Results Sixty-five of 71 included studies were meta-analysable. These 65 studies elicited 71 comparisons which, when meta-analysed, suggested that self-care support interventions were effective at 6-month [standardised mean difference (SMD) = −0.20; 95% confidence interval (CI) −0.28 to −0.11] and 12-month (SMD = −0.12; 95% CI −0.17 to −0.06) follow-ups. However, judged against Cochrane criteria, the studies were mostly low quality. Key elements of self-care support identified in the perceptions review were the acquisition of knowledge and skills, peer support and the relationship with the self-care support agent; CYP also had different perceptions from adults about what is important in self-care support. The mapping exercise identified 27 providers of 33 self-care support services. According to the case study data, effective self-care support services are predicated on flexibility; straightforward access; non-judgemental, welcoming organisations and staff; the provision of time and attention; opportunities to learn and practise skills relevant to self-care; and systems of peer support. Conclusions Mental health self-care support interventions for CYP are modestly effective in the short to medium term. Self-care support can be conceptualised as a process which has overlap with ‘recovery’. CYP and their families want choice and flexibility in the provision of such interventions and a continued relationship with services after the nominal therapy period. Those delivering self-care support need to have specific child-centred attributes. Future work Future work should focus on under-represented conditions (e.g. psychosis, eating disorders, self-harm); the role of technology, leadership and readiness in self-care support; satisfaction in self-care support; the conceptualisation of self-care support in CYP’s mental health; and efficacy and cost-effectiveness

Neuroanatomical correlates of working memory performance in Neurofibromatosis 1

Introduction: Neurofibromatosis 1 (NF1) is a single-gene disorder associated with cognitive impairments, particularly with deficits inworking memory. Prior research indicates that brain structure is affected in NF1, but it is unclear how these changes relate to aspectsof cognition.Methods: 29 adolescents aged 11-17 years were compared to age and sex-matched controls. NF1 subjects were assessed using detailedmultimodal measurements of working memory at baseline followed by a 3T MR scan. A voxel-based morphometry approach was usedto estimate the total and regional gray matter(GM) volumetric differences between the NF1 and control groups. The working memory metrics were subjected to a principal component analysis (PCA) approach.Results: The NF1 groups showed increased gray matter volumes in the thalamus, corpus striatum, dorsal midbrain and cerebellumbilaterally in the NF1 group as compared to controls. Principal component analysis on the working memory metrics in the NF1 groupyielded three independent factors ref lecting high memory load, low memory load and auditory working memory. Correlation analysesrevealed that increased volume of posterior cingulate cortex, a key component of the default mode network (DMN) was significantlyassociated with poorer performance on low working memory load tasks.Conclusion: These results are consistent with prior work showing larger subcortical brain volumes in the NF1 cohort. The strongassociation between posterior cingulate cortex volume and performance on low memory load conditions supports hypotheses of deficient DMN structural development, which in turn may contribute to the cognitive impairments in NF1

Psychosocial screening and management of young people aged 18-25 years with diabetes: psychosocial screening for diabetes

Background: Routine psychosocial screening and management of people with diabetes is recommended. Aims: To profile demographic, medical and psychosocial characteristics of young people with diabetes, and to develop a screening tool and care pathway for routine use. Methods: Indices of diabetes control and recorded diabetes complications were complimented by psychosocial screening tools assessing psychological, diabetes specific and perceived stress (Kessler 10, Problem Area in Diabetes, Perceived Stress Scale), well-being (World Health Organization Well Being Index-5), disordered eating (Eating Disorder Risk Inventory-3 Risk Composite), compensatory behaviour questionnaire, social support (Multidimensional Scale of Perceived Social Support), resilience (Connor Davidson Resilience Scale – 2 item) and financial concerns. Service provision and demographic data were also collected. Diabetes and mental health clinicians then identified a subset of measures to use for routine screening along with care pathways. Results: Psychosocial screening was well accepted. Participants (151) had suboptimal glycaemic control (glycated haemoglobin 8.0 interquartile range 1.8%/64 interquartile range 22 mmol/mol). Severe diabetes-related distress (Problem Area in Diabetes ≥40) was found in 19.4% and 26.0% reported difficulties managing healthcare costs. A mental health disorder was likely in 9.7%, whilst 23.4% had high Kessler 10 scores. Low World Health Organization Well Being Index-5 scores (≤13) were seen in 29.0%. Risk for an eating disorder (Eating Disorder Risk Inventory-3 Risk Composite) was 12.7%, whereas approximately 36.0% had disturbed eating behaviours. Conclusion: Psychosocial screening of young adults with diabetes identified complex needs. A brief psychosocial screening tool and associated care pathways were developed for routine use in a young adult tertiary referral diabetes clinic. The tool assesses constructs, such as diabetes distress, depression, anxiety, well-being, hypoglycaemia-unawareness, fear of hypoglycaemia, social support, weight, shape and eating concerns and financial concerns. This will provide a longitudinal data source for further research to inform clinical practice

Multiwavelength studies of MHD waves in the solar chromosphere: An overview of recent results

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool photosphere and the intensely heated transition region and corona. Compressible and incompressible waves propagating through the chromosphere can supply significant amounts of energy to the interface region and corona. In recent years an abundance of high-resolution observations from state-of-the-art facilities have provided new and exciting ways of disentangling the characteristics of oscillatory phenomena propagating through the dynamic chromosphere. Coupled with rapid advancements in magnetohydrodynamic wave theory, we are now in an ideal position to thoroughly investigate the role waves play in supplying energy to sustain chromospheric and coronal heating. Here, we review the recent progress made in characterising, categorising and interpreting oscillations manifesting in the solar chromosphere, with an impetus placed on their intrinsic energetics.Comment: 48 pages, 25 figures, accepted into Space Science Review

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
