Centralized Project-Specific Metadata Platforms: Toolkit Provides New Perspectives on Open Data Management within Multi-Institution and Multidisciplinary Research Projects

Open science and open data within scholarly research programs are growing both in popularity and by requirement from grant funding agencies and journal publishers. A central component of open data management, especially on collaborative, multidisciplinary, and multi-institutional science projects, is documentation of complete and accurate metadata, workflow, and source code in addition to access to raw data and data products to uphold FAIR (Findable, Accessible, Interoperable, Reusable) principles. Although best practice in data/metadata management is to use established internationally accepted metadata schemata, many of these standards are discipline-specific making it difficult to catalog multidisciplinary data and data products in a way that is easily findable and accessible. Consequently, scattered and incompatible metadata records create a barrier to scientific innovation, as researchers are burdened to find and link multidisciplinary datasets. One possible solution to increase data findability, accessibility, interoperability, reproducibility, and integrity within multi-institutional and interdisciplinary projects is a centralized and integrated data management platform. Overall, this type of interoperable framework supports reproducible open science and its dissemination to various stakeholders and the public in a FAIR manner by providing direct access to raw data and linking protocols, metadata and supporting workflow materials

Reduced dimensionality spin-orbit dynamics of CH3 + HCl reversible arrow CH4 Cl on ab initio surfaces

A reduced dimensionality quantum scattering method is extended to the study of spin-orbit nonadiabatic transitions in the CH3 + HCl reversible arrow CH4 + Cl(P-2(J)) reaction. Three two-dimensional potential energy surfaces are developed by fitting a 29 parameter double-Morse function to CCSD(T)/IB//MP2/cc-pV(T+d)Z-dk ab initio data; interaction between surfaces is described by geometry-dependent spin-orbit coupling functions fit to MCSCF/cc-pV(T+d)Z-dk ab initio data. Spectator modes are treated adiabatically via inclusion of curvilinear projected frequencies. The total scattering wave function is expanded in a vibronic basis set and close-coupled equations are solved via R-matrix propagation. Ground state thermal rate constants for forward and reverse reactions agree well with experiment. Multi-surface reaction probabilities, integral cross sections, and initial-state selected branching ratios all highlight the importance of vibrational energy in mediating nonadiabatic transition. Electronically excited state dynamics are seen to play a small but significant role as consistent with experimental conclusions. (C) 2011 American Institute of Physics. [doi:10.1063/1.3592732

Regionally acquired intestinal failure data suggest an underestimate in national service requirements

Objectives, setting and patients: With complete case referral for prolonged parenteral nutrition (PN) beyond term equivalent, serving a stable population of 1.25 million people, we describe the long-term outcome and survival of patients referred to an intestinal failure (IF) nutrition support team over the first 8 years of existence at a regional paediatric centre, and extrapolate to potential numbers of national home parenteral nutrition (HPN) cases and intestinal transplantation data. Design and outcome measures: Retrospective analysis detailing patient demographics, interventions, use of HPN, occurrence of intestinal failure-associated liver disease (IFALD), and outcomes of enteral adaptation, survival, and referral for and receipt of organ transplantation. Results: 23 patients were referred over 8 years, 20 being PN dependent within the neonatal period. Diagnoses included short bowel syndrome (SBS) (18), neuromuscular abnormalities (4) and congenital enterocyte disorder (1). 12 696 days of PN were delivered with 314 confirmed episodes of sepsis at a median of 12 episodes per patient. 144 central venous catheters (CVCs) were required at a median of four per patient. IFALD occurred in 17 (73%) patients, with 10 (44%) referred for transplant assessment. Thirteen (56%) children received HPN. Overall mortality was 44%. A significant predictor for survival in the SBS group was residual bowel >40 cm (82% vs 28%, p = 0.049). Conclusions: Survival for IF at 56% was lower than reported from non-UK supra-regional centres, and nationally collected data, possibly reflecting pre-selected referral populations. Data from regional centres with complete ascertainment may be important both when counselling parents and when planning regional and national HPN and IF specialist services

Convolutional Recurrent Neural Networks for Small-Footprint Keyword Spotting

Keyword spotting (KWS) constitutes a major component of human-technology interfaces. Maximizing the detection accuracy at a low false alarm (FA) rate, while minimizing the footprint size, latency and complexity are the goals for KWS. Towards achieving them, we study Convolutional Recurrent Neural Networks (CRNNs). Inspired by large-scale state-of-the-art speech recognition systems, we combine the strengths of convolutional layers and recurrent layers to exploit local structure and long-range context. We analyze the effect of architecture parameters, and propose training strategies to improve performance. With only ~230k parameters, our CRNN model yields acceptably low latency, and achieves 97.71% accuracy at 0.5 FA/hour for 5 dB signal-to-noise ratio.Comment: Accepted to Interspeech 201

Mandatory Reporting of Child Abuse: Royal College of Paediatrics and Child Health Policy, August 2023

RCPCH is asking the government to consider five key points before considering whether a mandatory reporting duty is best for children in England and Wales:1. All types of child abuse much fall under any mandatory reporting duty2. A children’s rights-based approach must be followed and a children’s rights impact assessment must be carried out3. A Government systems impact assessment must be carried out4. Measurable outcomes for children must be built into any plans5. Clearer definitions must be provided before further consultatio

Changes in admission thresholds in English Emergency Departments

YesBackground: The most common route to a hospital bed in an emergency is via an emergency department (ED). Many recent initiatives and interventions have the objective of reducing the number of unnecessary emergency admissions. We aimed to assess whether ED admission thresholds had changed over time taking account of the casemix of patients arriving at ED. Methods: We conducted a retrospective cross-sectional analysis of more than 20 million attendances at 47 consultant-led emergency departments in England between April 2010 and March 2015. We used mixed- effects logistic regression to estimate the odds of a patient being admitted to hospital and the impact of a range of potential explanatory variables. Models were developed and validated for four attendance subgroups : ambulance-conveyed children; walk-in children; ambulance-conveyed adults; and walk-in adults. Results: 23.8% of attendances were for children aged under 18 years, 49.7% were female and 30.0% were conveyed by ambulance. The number of ED attendances increased by 1.8% per annum between April 2010 – March 2011 (year 1) and April 2014 –March 2015 (year 5). The proportion of these attendances that were admitted to hospital changed little between year 1 (27.0%) and year 5 (27.5%). However, after adjusting for patient and attendance characteristics the odds of admission over the five year period had reduced by: 15.2% (95% CI 13.4% - 17.0%) for ambulance-conveyed children; 22.6% (95% CI 21.7%-23.5%) for walk-in children; 20.9% (95% CI 4%-21.5%) for ambulance conveyed adults; and 22.9% (95% CI 22.4%-23.5%) for walk-in adults. Conclusions: The casemix-adjusted odds of admission via ED to NHS hospitals in England have decreased since April 2010. EDs are admitting a similar proportion of patients to hospital despite increases in the complexity and acuity of presenting patients. Without these threshold changes, the number of emergency admissions would have been 11.9% higher than was the case in year 5

Interventions to improve infant and young child feeding practices in Ethiopia : a systematic review

Objective In Ethiopia, despite the implementation of several interventions to improve infant and young child feeding (IYCF) practices, no published studies have highlighted the most effective IYCF interventions in the country. This systematic review investigated the impacts of various interventions on IYCF in Ethiopia. Source of information A systematic search was conducted on seven computerised bibliographic databases (Embase, ProQuest Central, Scopus, PsycINFO, Web of Science, MEDLINE/PubMed and CINAHL) to locate experimental or quasi-experimental studies published between the year 2000 and May 2021. Study eligibility criteria Interventional studies that measured IYCF indicators (early initiation of breast feeding (EIBF), exclusive breast feeding (EBF), the introduction of complementary foods, minimum dietary diversity (MDD), minimum meal frequency (MMF) and minimum acceptable diet) as outcome variables were included. Study appraisal and synthesis All included studies were examined for biases related to interventional studies (ie, selection bias, performance bias, attrition bias, detection bias and reporting bias). Author reports of effect size measures were used to narratively report the findings of each study. Results Of the 23 eligible studies, 14 studies were quasi-experimental and 9 studies were cluster randomised trials (CRTs). Eight quasi-experimental studies had a serious risk of bias, while two CRTs had a high risk of bias. Four studies for EBF and six studies for EIBF showed significant impacts of policy advocacy, health service strengthening, interpersonal communication, community mobilisation and mass media campaigns. Six studies for MDD and three studies for MMF indicated significant effects of community-level and health facility complementary feeding promotions on infants and young children. Interventions that delivered in combination increased the impacts in improving EIBF, MDD and MMF compared with a single intervention. Conclusion Our review showed that 12 out of 21 eligible studies that implemented in the form of community-level and health facility interventions improved EIBF, EBF, and/or MDD in Ethiopia

South Africa’s private wildlife ranches protect globally significant populations of wild ungulates

Reversing biodiversity loss is a global imperative that requires setting aside sufficient space for species. In South Africa, an estimated area of 20 million ha is under wildlife ranching, a form of private land enterprise that adopts wildlife-based land uses for commercial gain. This land has potential to contribute towards biodiversity conservation, but the extent to which this occurs has not been evaluated. Using structured questionnaires of 226 wildlife ranchers, we assessed how the sector contributes towards the conservation of ungulates and elephants (hereafter herbivores). Overall, 40 herbivore species were present across the sample, where individual ranches had a mean of 15.0 (± 4.8) species, 1.9 (± 1.5) threatened species, and 3.6 (± 3.1) extralimital species per property. In comparison to 54 state PAs, wildlife ranches had significantly higher species richness, more threatened species but more extralimital species when property/reserve size was controlled for. Ranches conducting trophy hunting had similar species richness and numbers of extralimital species per ha, but fewer threatened species when compared to ranches conducting ecotourism. We estimate that 4.66–7.25 million herbivores occur on ranches nationally, representing one of the few examples on earth where indigenous mammal populations are thriving and demonstrating how sustainable use can lead to rewilding. We discuss the potential negative impacts of widespread game fencing on landscape fragmentation and gene flow, as well as how the widespread occurrence of extralimital species may lead to hybridisation, biotic homogenisation, and changes to vegetation dynamics. Despite these challenges, commercial wildlife ranching offers a viable option for conserving large mammalian herbivore biodiversity.Supplementary File 1.
