AbstractEpidemiological data reveal that there is a need for prevention measures specifically targeted at children with low SES. In the German federal state Mecklenburg-Western Pomerania preschools in socially deprived regions can apply for additional funds to support children with developmental risks. Mandatory criteria for obtaining these funds involve an annual assessment of all children using the “Dortmunder Developmental Screening for Preschools (DESK 3–6 R).” This instrument can detect and monitor developmental risks in the domains fine motor skills, gross motor skills, language, cognition, and social development. In this study, we examine the domain “Attention and concentration,” which is included for the 5 to 6-year-old age group, using data from two consecutive survey waves (sw). Research questions: (1) Does the prevalence rate ratio (PRR) improve over time? (2) Is the rate of improvements (developmental risk at sw1, no developmental risk at sw2) higher than the rate of deteriorations (no developmental risk at sw1, developmental risk at sw2)? Prospective cohort analysis (n = 940). The prevalence rate of a developmental risk in this DESK domain decreases over time (PRR = 0.78; p = 0.019). The ratio of the rate of improvements is 8.47 times higher than the rate of deteriorations. The results provide evidence of the effectiveness of targeted intervention measures in preschools focusing on skills that improve attention and concentration. This is significant considering the small-time interval and the categorization method of DESK scores. Nevertheless, over the same time period, the DESK results of some children deteriorated. Therefore, preschools also have to be aware that it is natural for some children to show modest declines in their skills over time.

Published: March 2022

AbstractProbabilistic topic modeling algorithms like Latent Dirichlet Allocation (LDA) have become powerful tools for the analysis of large collections of documents (such as papers, projects, or funding applications) in science, technology an innovation (STI) policy design and monitoring. However, selecting an appropriate and stable topic model for a specific application (by adjusting the hyperparameters of the algorithm) is not a trivial problem. Common validation metrics like coherence or perplexity, which are focused on the quality of topics, are not a good fit in applications where the quality of the document similarity relations inferred from the topic model is especially relevant. Relying on graph analysis techniques, the aim of our work is to state a new methodology for the selection of hyperparameters which is specifically oriented to optimize the similarity metrics emanating from the topic model. In order to do this, we propose two graph metrics: the first measures the variability of the similarity graphs that result from different runs of the algorithm for a fixed value of the hyperparameters, while the second metric measures the alignment between the graph derived from the LDA model and another obtained using metadata available for the corresponding corpus. Through experiments on various corpora related to STI, it is shown that the proposed metrics provide relevant indicators to select the number of topics and build persistent topic models that are consistent with the metadata. Their use, which can be extended to other topic models beyond LDA, could facilitate the systematic adoption of this kind of techniques in STI policy analysis and design.

Abstract
In this article, we discuss the development of prognostic machine learning (ML) models for COVID-19 progression, by focusing on the task of predicting ICU admission within (any of) the next 5 days. On the basis of 6,625 complete blood count (CBC) tests from 1,004 patients, of which 18% were admitted to intensive care unit (ICU), we created four ML models, by adopting a robust development procedure which was designed to minimize risks of bias and over-fitting, according to reference guidelines. The best model, a support vector machine, had an AUC of .85, a Brier score of .14, and a standardized net benefit of .69: these scores indicate that the model performed well over a variety of prediction criteria. We also conducted an interpretability study to back up our findings, showing that the data on which the developed model is based is consistent with the current medical literature. This also demonstrates that CBC data and ML methods can be used to predict COVID-19 patients’ ICU admission at a relatively low cost: in particular, since CBC data can be quickly obtained by means of routine blood exams, our models could be used in resource-constrained settings and provide health practitioners with rapid and reliable indications.

Electrodeposited Ni-Cu Coatings with Hierarchical Surface Morphology
Authors: Staroń S. , Ledwig P. , Dubiel B. 
Published: March 2022

AbstractIn recent years, Ni-Cu alloy coatings obtained by electrolytic deposition have received increasing interest, because of their good anti-corrosive, mechanical, magnetic, electrical, and decorative properties. Further applications of these coatings for electrode materials and catalysts may be possible by developing hierarchical surface morphology, and thus a combination of high surface roughness, high microhardness, and good corrosion resistance. In the present work, four types of Ni-Cu alloy coatings were deposited in a single-step process from electrolytic baths with Cu2+:Ni2+concentrations equal to 1:30, 1:20, 1:15, and 1:10 using deposition current densities of 2 A/dm2and 4 A/dm2. The surface morphology of the coatings was characterized using a scanning electron microscope and an optical profilometer. The coatings exhibited a nodular morphology, which with the change of the Cu2+:Ni2ratio and the current parameters changed from smooth and compact to rougher with regularly spaced nodular microprotrusions. Thus, a hierarchical surface morphology was obtained. Transmission electron microscopy investigations revealed that the fine-grained microstructure of the coatings consisted of theγsolid solution, as well as the metastable intermetallic L10NiCu phase. The differences in the Cu concentration at the cross-sections demonstrated by quantitative microanalysis of the chemical composition indicated a dendritic growth of the coatings and a preferential reduction of copper ions over nickel ions. The coatings were also characterized by a microhardness greater than 3.71 GPa and good electrochemical corrosion resistance in chloride media. Coatings with hierarchical morphology and high surface roughness showed a higher corrosion current. The study provides a new method for electrodeposition hierarchical Ni-Cu coatings under specific chemical compositions of the electrolytic bath and current conditions, characterized by a combination of promising properties for electrode and catalytic applications.Graphical Abstract

Published: March 2022

AbstractThe progressively more demanding needs of emissions and costs reduction in the transportation industry are pushing engineers towards the use of increasingly lightweight structures. This goal can be achieved only if dissimilar and/or new materials, including polymers and composites, are joined together to create complex structures. Conventional fusion welding processes have often been proven inadequate to this task because of the high heat input reducing the joint mechanical properties or even making the joining process impossible. Joining by forming technologies take advantage on the plastic deformation to create sound joints out of even very dissimilar materials. Over the last 25 years, several new processes, with increasing potential in effectively joining virtually every structural material, have been invented and developed. In the paper, a comprehensive overview of the most utilized joining by forming processes is given. For each process, an analysis of the current research trends and hot topics is provided, highlighting strengths and weaknesses for industrial applications.

AbstractObjective:We investigated real-world vaccine effectiveness for Oxford-AstraZeneca (ChAdOx1) and CoronaVac against laboratory-confirmed severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare workers (HCWs).Methods:We conducted a retrospective cohort study among HCWs (aged ≥18 years) working in a private healthcare system in Brazil between January 1, 2021 and August 3, 2021, to assess vaccine effectiveness. We calculated vaccine effectiveness as 1 − rate ratio (RR), with RR determined by adjusting Poisson models with the occurrence of SARS-CoV-2 infection as the outcome and the vaccination status as the main variable. We used the logarithmic link function and simple models adjusting for sex, age, and job types.Results:In total, 13,813 HCWs met the inclusion criteria for this analysis. Among them, 6,385 (46.2%) received the CoronaVac vaccine, 5,916 (42.8%) received the ChAdOx1 vaccine, and 1,512 (11.0%) were not vaccinated. Overall, COVID-19 occurred in 6% of unvaccinated HCWs, 3% of HCWs who received 2 doses of CoronaVac vaccine, and 0.7% of HCWs who received 2 doses of ChAdOx1 vaccine (P < .001). In the adjusted analyses, the estimated vaccine effectiveness rates were 51.3% for CoronaVac, and 88.1% for ChAdOx1 vaccine. Both vaccines reduced the number of hospitalizations, the length of hospital stay, and the need for mechanical ventilation. In addition, 19 SARS-CoV-2 samples from 19 HCWs were screened for mutations of interest. Of 19 samples, 18 were the γ (gamma) variant.Conclusions:Although both COVID-19 vaccines (viral vector and inactivated virus) can significantly prevent COVID-19 among HCWs, CoronaVac was much less effective. The COVID-19 vaccines were also effective against the dominant γ variant.
Does the family care best? Ideals of care in a familialistic care regime

Published: March 2022

AbstractInformal caregiving for older family members is increasingly recognized and encouraged by public policies. This is even more the case in familialistic countries such as Austria. This article aims to examine the role of the family in the care culture of a familialistic care regime through the experiences of care dyads combining upwards intergenerational family care and formal care services. The analysis is based on framework analysis of 48 face-to-face interviews, almost all conducted separately, with 24 care dyads of older care users (average age 86 years old with moderate to high care needs) and their main informal carers in Austria combining formal and informal care. A quarter of caregivers and care receivers were male. We identified four different ideals (family care, preferences, involvement, gendered care) which were distributed across different groups of Socio-Economic Status (SES) and described by women and men.
Building the Future from the Present: Imagining Post-Growth, Post-Productivist Ecosocial Policy
Authors: DUKELOW FIONA , MURPHY MARY P. 
Published: March 2022

AbstractThe environment remains on the margins of social policy. Bringing degrowth literature into conversation with social policy debates about decommodification, we argue that a re-imagined decommodification remains central to addressing the social-ecological challenges we face and to forging a post-growth, post-productivist ecosocial welfare state. We explore the implications of this for re-imagining and mapping three core areas of an ecosocial welfare state revolving around the work/welfare/care nexus: the redistribution of time across work and care; repurposing of active labour market measures; and reorienting cash transfers and services. In each case we discuss what decommodified social policy in the service of a post-growth, post-productivist future might entail. Acknowledging challenges, we identify how instances of prefiguration of policy programmes and experiments across various countries offer concrete compass points for further transformation and a necessary paradigmatic shift.
Practicalities of a spiral-inspired approach
Authors: Leveridge James 
Published: March 2022

AbstractSwanwick and Tillman set out three levels at which their “Sequence of Musical Development” may implicate music teaching: general curriculum planning, individual development, and the role of theteacher. From the perspective of a practitioner working as a secondary music teacher in England, this article critiques the practicalities of adopting an approach inspired by Swanwick and Tillman’s theory. Although recognising the challenges that music teachers face in the current context for music education, this article argues that educators should carefully consider how musical learning is structured, both in curriculum planning and approach.
Reflections on New Zealand music education through the lens of Swanwick and Tillman’s model of musical development
Authors: Thorpe Vicki , McPhail Graham 
Published: March 2022

AbstractIn this paper, we provide a reflection upon the influence of the Swanwick–Tillman (ST) model (1986) from the perspectives of music research in Aotearoa New Zealand. In this paper we take stock of where music education in New Zealand currently sits in relation to the Swanwick Tillman theory of musical development. We examine the strengths and the weakness of the model 35 years on to ask what it might still offer music educators in a context where issues of culture and colonisation have taken centre stage. We also reflect upon the impact of a visit to New Zealand by Keith Swanwick in 1989. Despite the postmodern or colonial critiques we might make now, we consider if the model may still signify a holistic way of conceiving music development and might still have implications for curriculum design and curriculum making in the 21stcentury.

AbstractContinuing climate change may cause shifts in the adaptive ranges of plant species. But this impact is less understood for many species in the tropics. Here, we examined the distribution of the current and future potential suitable habitats of two native forest spices Piper capense and Aframomum corrorima. We have used MaxEnt software to predict the current and future suitable habitats of these species. Two future climate change scenarios, that is, middle (Representative Concentration Pathway [RCP 4.5]) and extreme (RCP 8.5) scenarios for years 2050 and 2070, were used. A total of 60 and 74 occurrence data of P. capense and A. corrorima, respectively, and 22 environmental variables were included. The effects of elevation, solar radiation index (SRI) and topographic position index (TPI) on suitable habitats of these species were tested using linear model in R. Precipitation of the driest quarter, SRI and TPI significantly affect future suitable habitats of P. capense and A. corrorima. Furthermore, there are significant elevational shifts of suitable habitats for both species under future scenarios (P < 0.001). These novel suitable habitats are located in moist Afromontane and Combretum-Terminalia vegetations. Our results suggest that conservation planning for these species should consider climate change factors including assisted migration.
Characteristics and long-term outcome for congenital left main coronary artery atresia

Published: March 2022

AbstractThe prevalence of congenital left main coronary artery atresia is very low. We report the characteristics and long-term outcomes of four children with left main coronary artery atresia. Three patients had heart murmurs due to mitral regurgitation at less than 1 year old. Their myocardial ischaemia worsened on exercise with aging. In the fourth patient, hypertrophic cardiomyopathy and Noonan syndrome were suspected at 1 year old. The development of communicating arteries between the conus branch and the left anterior descending artery was detected at 7 years old. The left main coronary artery atresia was confirmed by a selective coronary angiogram at 15 years old. Congenital left main coronary artery atresia could not be diagnosed by two-dimensional echocardiography; however, the left coronary arteries were small. Two patients underwent coronary artery bypass grafting of the left anterior descending artery using the left internal thoracic artery at 3 years and 6 years old, respectively. Two patients had an angioplasty with a cut back at the orifice of the left coronary artery at 2 years old and 17 years old, respectively. Two patients had no cardiac events without medication for more than 30 years after the operation. We must differentiate the diagnosis of left main coronary artery atresia in the small left coronary arteries with mitral regurgitation during the first year. Coronary artery revascularisation and mitral annuloplasty are needed. The long-term outcome of both coronary artery bypass grafting and angioplasty were good. The degree of mitral regurgitation after surgery may affect the prognosis.
Softness in the Law of International Watercourses: The (E)merging Normativities of China's Lancang-Mekong Cooperation
Authors: Devlaeminck David J. 
Published: March 2022

AbstractThe law of international watercourses consists mainly of a series of bilateral, multilateral, regional, and global agreements that establish binding rules through which state parties jointly manage transboundary water resources. China similarly manages its shared freshwaters through a series of bilateral agreements. Increasingly, however, it relies on non-binding soft law instruments to manage these resources with its riparian neighbours. An important example of this is the Lancang-Mekong Cooperation, a branch of the Belt and Road Initiative. Its use of soft instruments, which recognize international law and promote projects, displays evidence of merging and emerging normativities, ensuring that it is capable of playing both a supporting and a developmental role in the law of international watercourses.

AbstractThis study presents results from magnetic field line conjunctions between the medium‐Earth orbiting Demonstration and Science Experiments (DSX) satellite and the low‐Earth orbiting (LEO) very low frequencies (VLF) Propagation Mapper (VPM) satellite. DSX transmitted at VLF toward VPM, which was equipped with a single‐axis dipole electric field antenna, when the two spacecraft passed near the same magnetic field line. VPM did not observe DSX signals in any of the 27 attempted conjunction experiments; the goal of this study, therefore, is to explain why DSX signals were not received. Explanations include (a) the predicted power at LEO from DSX transmissions was too low for VPM to observe; (b) VPM's trajectory missed the “spot” of highest intensity due to the focused ray paths reaching LEO; or (c) rays mirrored before reaching VPM. Different combinations of these explanations are found. We present ray‐tracing analysis for each conjunction event to predict the distribution of power and wave normal angles in the vicinity of VPM at LEO altitudes. We find that, for low‐frequency (below 4 kHz) transmissions, nearly all rays mirror before reaching LEO, resulting in low amplitudes at LEO. For mid‐ and high‐frequency transmissions (∼8 and 28 kHz respectively), the power at LEO is above the noise threshold of the VPM receiver (between 0.5 μV/m and 1 μV/m). We conclude that the antenna efficiency and plasmasphere model are critical in determining the predicted power at LEO, and are also the two most significant sources of uncertainty that could explain the apparent discrepancy between predicted amplitudes and VPM observations.
Real‐Time 3‐D Modeling of the Ground Electric Field Due To Space Weather Events. A Concept and Its Validation
Authors: Kruglyakov Mikhail , Kuvshinov Alexey , Marshalko Elena 
Published: March 2022

AbstractWe present a methodology that allows researchers to simulate in real time the spatiotemporal dynamics of the ground electric field (GEF) in a given 3‐D conductivity model of the Earth based on continuously augmented data on the spatiotemporal evolution of the inducing source. The formalism relies on the factorization of the source by spatial modes (SM) and time series of respective expansion coefficients and exploits precomputed GEF kernels generated by corresponding SM. To validate the formalism, we invoke a high‐resolution 3‐D conductivity model of Fennoscandia and consider a realistic source built using the Spherical Elementary Current Systems (SECS) method as applied to magnetic field data from the International Monitor for Auroral Geomagnetic Effect network of observations. The factorization of the SECS‐recovered source is then performed using the principal component analysis. Eventually, we show that the GEF computation at a given time instant on a 512 × 512 grid requires less than 0.025 s provided that GEF kernels due to pre‐selected SM are computed in advance. Taking the 7–8 September 2017 geomagnetic storm as a space weather event, we show that real‐time high‐resolution 3‐D modeling of the GEF is feasible. This opens a practical opportunity for GEF (and eventually geomagnetically induced currents) nowcasting and forecasting.
