Background: Mental health disorders in children and young people (CYP) are increasing but the provision of current evidence-based treatment for common mental health problems is limited. Treatment effects vary widely with no clear superiority of a single treatment approach. Further evaluation of contemporary and effective treatments in CYP is needed.

Structural transformation is a key indicator of economic development. We present the first time series of male labour sectoral shares for England and Wales before 1800, using a large sample of probate and apprenticeship data to produce national and county-level estimates. England experienced a rapid decline in the share of workers in agriculture between the early seventeenth and the beginning of the eighteenth centuries, associated with rising agricultural and especially industrial productivity; Wales saw few changes.

Indigenous communities in the Arctic often face unique drinking water quality challenges related to inadequate infrastructure and environmental contamination; however, limited research exists on waterborne parasites in these communities. This study examined Giardia and Cryptosporidium in untreated surface water used for drinking in Iqaluit, Canada. Water samples (n = 55) were collected weekly from June to September 2016 and tested for the presence of Giardia and Cryptosporidium using microscopy and polymerase chain reaction (PCR).

Background: Parenting programmes are recommended for conduct disorders in 5-11 year olds, but ineffective for 25-33%. A feasibility trial was needed to determine whether a confirmatory trial of second-line, manualised short-term psychoanalytic child psychotherapy (mPCP) versus treatment as usual (TaU) is practicable.

Method: This was a two-arm, pragmatic, parallel-group, multi-centre, individually-randomised controlled feasibility trial with blinded outcome assessment.

Abstract: The Anthropocene imposes new challenges for governments, demanding capabilities for dealing with complexity and uncertainty. In this paper we examine how effective governing of social-biophysical dynamics is constrained by current processes and systems of government. Framing choices and structural determinants combine to create governance deficits in multiple domains, particularly in relation to the governing of complex larger-scale social-biophysical systems.

Purpose: The 2014 outbreak of Ebola virus disease (EVD) in West Africa was the largest in history. Starting in September 2014, International Medical Corps (IMC) operated five Ebola treatment units (ETUs) in Sierra Leone and Liberia. This paper explores how future infectious disease outbreak facilities in resource-limited settings can be planned, organized, and managed by analyzing data collected on water, sanitation, and hygiene (WASH) and infection prevention control (IPC) protocols.

Students with transcription disabilities (dysgraphia/impaired handwriting, = 13 or dyslexia/impaired word spelling, = 16) or without transcription disabilities (controls) completed transcription and translation (idea generating, planning, and creating) writing tasks during fMRI connectivity scanning and compositions after scanning, which were coded for transcription and translation variables. Compositions in both groups showed diversity in genre beyond usual narrative-expository distinction; groups differed in coded transcription but not translation variables. For the control group specific transcription or translation tasks during scanning correlated with corresponding coded transcription or translation skills in composition, but connectivity during scanning was not correlated with coded handwriting during composing in dysgraphia group and connectivity during translating was not correlated with any coded variable during composing in dyslexia group.

Background: The National Institute for Health and Care Excellence (NICE) recommends evidence-based parenting programmes as a first-line intervention for conduct disorders (CD) in children aged 5-11 years. As these are not effective in 25-33% of cases, NICE has requested research into second-line interventions. Child and Adolescent Psychotherapists (CAPTs) address highly complex problems where first-line treatments have failed and there have been small-scale studies of Psychoanalytic Child Psychotherapy (PCP) for CD.

Thirteen students with and twelve students without spelling disabilities judged whether sentences (1/3 all correct spellings, 1/3 with homonym foil, 1/3 with morpheme foil) were meaningful while event-related potentials (ERPs) were measured with EGI Geodesic EEG System 300 (128-channel hydro-cell nets). For N400, Rapid Automatic Switching (RAS) correlated with comprehending sentences with homonym foils in control group but with morpheme foils in SLD group. For P600, dictated spelling correlated with comprehending sentences with morpheme foils in the control group but solving anagrams with homonym foils in the SLD group.

For nanotechnology to meet its potential as a game-changing and sustainable technology, it is important to ensure that the engineered nanomaterials and nanoenabled products that gain entry to the marketplace are safe and effective. Tools and methods are needed for regulatory purposes to allow rapid material categorization according to human health and environmental risk potential, so that materials of high concern can be targeted for additional scrutiny, while material categories that pose the least risk can receive expedited review. Using carbon nanotubes as an example, we discuss how data from alternative testing strategies can be used to facilitate engineered nanomaterial categorization according to risk potential and how such an approach could facilitate regulatory decision-making in the future.

The decision to admit a frail older patient is rarely made by a geriatrician and often falls to staff in the emergency department (ED), who may not have the training to balance the risks, benefits and alternatives. We based a consultant geriatrician in the ED with the primary aim of facilitating admission prevention for older patients and this was achieved for 64% (543/848) of patients. A secondary aim was to facilitate direct admission to elderly care wards when admission was necessary, and this was achieved for 57% of admitted patients (174/305).

Deficits in social functioning are a core feature of autistic spectrum disorders (ASD), being linked to various cognitive and developmental factors, but there has been little attempt to draw on normative models of social cognition to understand social behaviour in ASD. The current study explored the utility of Crick and Dodge's (1994) information processing model to studying social cognition in ASD, and examined associations between social information processing patterns, theory of mind skills and social functioning. A matched-group design compared young people with Asperger syndrome with typically developing peers, using a social information processing interview previously designed for this purpose.

A heated ethical and professional debate occurred in the United States in the late 1980s over whether doctors had an ethical obligation to treat people with AIDS. Sparked by public refusals to treat by physicians, the debate was linked to changes in the epidemic and general tensions about the character of the profession. Despite widespread public consensus on the existence of a duty, the outcome of the debate was limited.

Three new photostable rylene dyes for applications in single molecule studies and membrane labelling have been synthesized and their photophysical properties were characterized. These dyes differ in the number of polyethylene glycol (PEG) chains attached to the core structure which is either a perylene derivate or a terrylene derivate. One perylene and one terrylene dye is modified with two PEG chains, and another terrylene derivate has four PEG chains.

Article Synopsis
  • Fe(III) montmorillonite clay modified with hexadecyltrimethylammonium (HDTMA(+)) cations showed enhanced catalytic activity for oxidative coupling reactions of hydrophobic organic substrates.
  • Different mixtures of organoclays were created with varying HDTMA(+) content (6% to 50%) and tested, revealing that optimal catalytic activity depended on the hydrophobicity of the substrate being used.
  • The study's findings emphasize the importance of tailoring the organic cation composition in clay catalysts to better match specific substrates or reactions, backed by structural analysis and molecular dynamics simulations indicating a heterogeneous arrangement of cations.
