AbstractDespite US federal legislation mandates institutions to provide meaningful access and participation to students and families in educational settings, culturally and linguistically diverse (CLD) families and caregivers of children in special education experience cultural and linguistic barriers. A Community Advisory Team (CAT) of parents, advocates, community interpreters and translators, researchers, and teachers explored CLD families' experiences and advocacy efforts. Critical bifocality and circuits of dispossession, privilege, and resistance informed the documentation of inequities and resistance to understand the linkages of structural arrangements of power. Focus groups with families (n = 21) speakers of Spanish, Portuguese, and Cantonese were conducted. Findings indicate perceived discrimination, poor and inadequate interpretation and translation services impact children's access to special education services, hinder family's communication with schools and reduce the perceptions of schools as trustworthy institutions. Families advocate relentlessly for their children and recommend schools listen to families and hire culturally and linguistically competent interpreters and translators. Community psychologists can make significant contributions to promote language justice in education settings through participatory approaches to inquiry that value CLD families' knowledge and expertise

AimWe aimed to identify subphenotypes among patients with out‐of‐hospital cardiac arrest (OHCA) with initial non‐shockable rhythm by applying machine learning latent class analysis and examining the associations between subphenotypes and neurological outcomes.MethodsThis study was a retrospective analysis within a multi‐institutional prospective observational cohort study of OHCA patients in Osaka, Japan (the CRITICAL study). The data of adult OHCA patients with medical causes and initial non‐shockable rhythm presenting with OHCA between 2012 and 2016 were included in machine learning latent class analysis models, which identified subphenotypes, and patients who presented in 2017 were included in a dataset validating the subphenotypes. We investigated associations between subphenotypes and 30‐day neurological outcomes.ResultsAmong the 12,594 patients in the CRITICAL study database, 4,849 were included in the dataset used to classify subphenotypes (median age: 75 years, 60.2% male), and 1,465 were included in the validation dataset (median age: 76 years, 59.0% male). Latent class analysis identified four subphenotypes. Odds ratios and 95% confidence intervals for a favorable 30‐day neurological outcome among patients with these subphenotypes, using group 4 for comparison, were as follows; group 1, 0.01 (0.001–0.046); group 2, 0.097 (0.051–0.171); and group 3, 0.175 (0.073–0.358). Associations between subphenotypes and 30‐day neurological outcomes were validated using the validation dataset.ConclusionWe identified four subphenotypes of OHCA patients with initial non‐shockable rhythm. These patient subgroups presented with different characteristics associated with 30‐day survival and neurological outcomes.
Bipolar Magnetic Molecules for Spin‐Polarized Electric Current in Molecular Junctions

AbstractElectrical control of spin transport at single molecule level is highly desired for molecular nanospintronics. By exploiting magnetic bistability of spin crossover complexes, the magnitude of spin polarization can be modulated. However, efficiently controlling the direction of spin polarization at single molecule level is still challenging. Here, we propose a general method to flip the transport electron spin simply by electrical gating in single molecule devices based on bipolar magnetic molecules (BMMs), of which the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) come from different spin channels. Thus, when the device's Fermi level is reversibly adjusted approaching either HOMO or LUMO by changing the polarity of the applied voltage gate, a 100 % spin polarized current with switchable spin direction is achievable. The proposed method is verified by the calculated electronic and transport properties of 9 potential transition metal coordination BMMs.

Published: May 2022

AbstractWe herein demonstrated an efficient method for the atroposelective construction of nine‐membered carbonate‐bridged biaryls through vinylideneortho‐quinone methide (VQM) intermediates. Diverse products with desirable pharmacological features were synthesized in satisfying yields and good to excellent enantioselectivities. In subsequent bioassays, several agents showed considerable antiproliferative activity via the mitochondrial‐related apoptosis mechanism. Further transformations produced more structural diversity and may inspire new ideas for developing functional molecules.

AbstractEs wurde eine Methode zur Synthese funktionalisierter alternierender Copolymere durch radikalische Polymerisation mit reversibler Deaktivierung entwickelt. Die Copolymerisation durch reversible Additions‐Fragmentierungs‐Kettenübertragung von Hexenylvinylether mit einem neuartigen fluorierten Divinylmonomer liefert alternierende Cyclopolymere, die chemoselektiv durch drei unterschiedliche orthogonale Funktionalisierungsreaktionen modifiziert werden können. Neben der Thiol‐En‐Click‐Reaktion und der Amidierung wurde eine dritte Funktionalisierung durch NHC‐katalysierte Umesterung oder Acylierung erreicht, womit eine kleine Bibliothek von alternierenden Terpolymeren vom ABC‐Typ dargestellt wurde.

AbstractThermomechanical and microstructural properties of oleogels developed with 2.1 to 15.7 Moles of monoglycerides/Mole of lecithin (MG/LC) were studied. The oleogels were developed (15°C) in vegetable (VO) and mineral (MO) oils using at each MG/LC 2% or 4% total mass of gelator. During oleogelation a synergistic interaction existed between the MG and the LC deriving in the development of MG‐LC cocrystals even below the gelators' minimum gelling concentration. In the VO, the oil with the highest relative polarity, the oleogels were structured by a network of β crystals where the cocrystals delayed the Lα → β polymorphic transition and worked as an active filler. In the MO, the oil with the lowest relative polarity, the development of cocrystals was favored while the Lα → β transition occurred just in the 15.7 MG/LC oleogels. Then, at all MG/LC the VO oleogels with 2% or 4% total gelator concentration achieved higher G′ than MO oleogels. However, the presence of β crystals in VO oleogels will result in deleterious effects in shorter time than in MO oleogels. In both oils the oleogels with the highest G′ and gel‐like rheological behavior were achieved at 8.1 MG/LC, particularly at 4% total gelator concentration. Under these conditions the β polymorph was limited developed in VO oleogels and completely absent in MO oleogels. Then, the rheology of MG‐LC oleogels with storage stability might be tailored using as design variables the MG/LC, the total gelator concentration, and the polarity of the oil.

AbstractA combination of experiments and theoretical models is used to study the mechanical and thermal properties of polydimethylsiloxane (PDMS) and magnetite nanoparticle‐reinforced PDMS composites with the potential for applications in biomedical implants for localized hyperthermia and photothermal ablation. Composite samples with varying weight fractions (0,1, 5, and 10 wt.%) of Fe3O4 nanoparticles were fabricated and tested to determine their stress–strain behavior and fracture toughness. The measured mechanical properties are also compared with predictions from composite and toughening models. The implications of the results are discussed for the design of plasmonic/magnetic nanocomposites with attractive combinations of mechanical and thermal properties that are relevant to laser hyperthermia and photo‐thermal‐ablation.

Abstract

Shark catches are common in small‐scale (artisanal) and recreational fisheries; the magnitudes of these catches remain poorly known and understudied, particularly in developing countries. Data from three sources were used to assess the composition of shark landings in these fisheries in Kenya: boat‐based recreational fishery tagging 1987–2016; observed landings from the Bycatch Assessment and Mitigation in the Western Indian Ocean Fisheries Project 2016–2017; and Catch Assessment Surveys landings data 2017–2020.
Eighteen species were identified among 1,215 sharks recorded in small‐scale fisheries between June 2016 and June 2017. Most of them belonged to the families Carcharhinidae (26%), Triakidae (23%) and Sphyrnidae (14%). Longlines (41%), drift gillnets (30%) and bottom‐set gillnets (21%) recorded the highest proportions of catches.
A total of 501 sharks comprising 16 species were recorded in the recreational tagging data between 1987 and 2016, caught using either trolling lines or rods and reels. The families Carcharhinidae (56%) and Sphyrnidae (12%) represented the highest proportion of the catch.
A generalized linear model was used to assess the effect of year, gear type, season and vessel propulsion mode on the variation in catches of sharks in small‐scale fisheries between 2017 and 2020. Catches were significantly higher in 2017 with high catch rates observed in longlines and handlines.
Findings from this study highlight the importance of citizen science by recreational fishers in increasing awareness around the risks and threats to shark populations. Strengthening of existing monitoring of shark interactions with small‐scale and recreational fisheries is important alongside the implementation of appropriate conservation and management measures such as reductions in fishing effort (e.g. prawn trawling) in nursery areas, prohibiting the capture of CITES‐protected species, and enforcing catch‐and‐release practices by sport fishers to ensure the long‐term sustainability of both the affected shark species and the livelihoods of the fishers.

From nostalgia to knowledge: Considering the personal dimensions of data lifecycles
Authors: Stahlman Gretchen R. 
Published: May 2022

AbstractData lifecycle models are used to visualize the stages data resources pass through from creation to completion of a research project and beyond. Although helpful, these models tend to depict idealized and impersonal circumstances that often involve curation actions taken by researchers themselves, while neglecting to represent dynamics particular to researchers' lives and careers. Meanwhile, research data are still infrequently managed successfully according to these models, which is a particular concern for “long tail” data, where sharing tends to depend on individual researchers' decisions and preservation actions. The paper addresses these considerations by exploring the ways in which long tail data lifecycles are entwined with human career lifecycles. Through interviews with astronomers, six affective dimensions that may impact data and career lifecycle dynamics are identified: painstakingness, loose ends, altruism, intellectual passion, legacy, and nostalgia. Building upon these insights and holistically drawing connections between human information behavior and data lifecycle modeling literature and frameworks, a researcher‐centered lifecycle model is proposed that seeks to depict the unique motivations and changing needs of researchers to share data throughout the courses of their careers. The paper concludes with suggestions for theoretical development and curatorial interventions in current data lifecycle modeling and data management practice.

AbstractBackgroundCongenital hydrocephalus (CH) comprises a heterogeneous group of birth anomalies with a wide‐ranging prevalence across geographic regions and registry type. The aim of the present study was to analyze the early neonatal case fatality rate (CFR) and total birth prevalence of newborns diagnosed with CH.MethodsData were provided by 25 registries from four continents participating in the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR) on births ascertained between 2000 and 2014. Two CH rates were calculated using a Poisson distribution: early neonatal CFR (death within 7 days) per 100 liveborn CH cases (CFR) and total birth prevalence rate (BPR) per 10,000 births (including live births and stillbirths) (BPR). Heterogeneity between registries was calculated using a meta‐analysis approach with random effects. Temporal trends in CFR and BPR within registries were evaluated through Poisson regression modeling.ResultsA total of 13,112 CH cases among 19,293,280 total births were analyzed. The early neonatal CFR was 5.9 per 100 liveborn cases, 95% confidence interval (CI): 5.4–6.8. The CFR among syndromic cases was 2.7 times (95% CI: 2.2–3.3) higher than among non‐syndromic cases (10.4% [95% CI: 9.3–11.7] and 4.4% [95% CI: 3.7–5.2], respectively). The total BPR was 6.8 per 10,000 births (95% CI: 6.7–6.9). Stratified by elective termination of pregnancy for fetal anomalies (ETOPFA), region and system, higher CFR were observed alongside higher BPR rates. The early neonatal CFR and total BPR did not show temporal variation, with the exception of a CFR decrease in one registry.ConclusionsFindings of early neonatal CFR and total BPR were highly heterogeneous among registries participating in ICBDSR. Most registries with higher CFR also had higher BPR. Differences were attributable to type of registry (hospital‐based vs. population‐based), ETOPFA (allowed yes or no) and geographical regions. These findings contribute to the understanding of regional differences of CH occurrence and early neonatal deaths.
A gentle tutorial on accelerated parameter and confidence interval estimation for hidden Markov models using Template Model Builder

Published: May 2022

AbstractA very common way to estimate the parameters of a hidden Markov model (HMM) is the relatively straightforward computation of maximum likelihood (ML) estimates. For this task, most users rely on user‐friendly implementation of the estimation routines via an interpreted programming language such as the statistical software environmentR. Such an approach can easily require time‐consuming computations, in particular for longer sequences of observations. In addition, selecting a suitable approach for deriving confidence intervals for the estimated parameters is not entirely obvious, and often the computationally intensive bootstrap methods have to be applied. In this tutorial, we illustrate how to speed up the computation of ML estimates significantly via theRpackageTMB. Moreover, this approach permits simple retrieval of standard errors at the same time. We illustrate the performance of our routines using different data sets: first, two smaller samples from a mobile application for tinnitus patients and a well‐known data set of fetal lamb movements with 87 and 240 data points, respectively. Second, we rely on larger data sets of simulated data of sizes 2000 and 5000 for further analysis. This tutorial is accompanied by a collection of scripts, which are all available in the Supporting Information. These scripts allow any user with moderate programming experience to benefit quickly from the computational advantages ofTMB.

AbstractObjectivesThe objectives of this study were to (1) examine the relationship between the number of head impacts sustained in a season of men's collegiate club ice hockey and behavioral traits of aggression and sensation seeking, and (2) explore the neural correlates of these behaviors using neuroimaging.DesignRetrospective cohort study.MethodsParticipants (n = 18) completed baseline surveys to quantify self‐reported aggression and sensation‐seeking tendencies. Aggression related to playing style was quantified through penalty minutes accrued during a season. Participants wore head impact sensors throughout a season to quantify the number of head impacts sustained. Participants (n = 15) also completed baseline anatomical and magnetic elastography neuroimaging scans to measure brain volumetric and viscoelastic properties. Pearson correlation analyses were performed to examine relationships between (1) impacts, aggression, and sensation seeking, and (2) impacts, aggression, and sensation seeking and brain volume, stiffness, and damping ratio, as an exploratory analysis.ResultsNumber of head impacts sustained was significantly related to the number of penalty minutes accrued, normalized to number of games played (r = .62, p < .01). Our secondary, exploratory analysis revealed that number of impacts, sensation seeking, and aggression were related to stiffness or damping ratio of the thalamus, amygdala, hippocampus, and frontal cortex, but not volume.ConclusionsA more aggressive playing style was related to an increased number of head impacts sustained, which may provide evidence for future studies of head impact prevention. Further, magnetic resonance elastography may aid to monitor behavior or head impact exposure. Researchers should continue to examine this relationship and consider targeting behavioral modification programs of aggression to decrease head impact exposure in ice hockey.
Fear of hypoglycemia—An underestimated problem
Authors: Przezak Agnieszka , Bielka Weronika , Molęda Piotr 
Published: May 2022

AbstractIntroductionFear of hypoglycemia (FOH) is a phenomenon that affects people with diabetes experiencing hypoglycemia. On the one hand, FOH is an adaptive mechanism that helps to protect patients from hypoglycemia and its consequences. On the other hand, the non‐normative level of FOH causes anxiety and tension, disturbs normal functioning, and makes normoglycemia maintenance difficult.ObjectiveThe main objective of this review was to describe factors influencing FOH and methods of measurement of FOH levels. Moreover, we highlighted the impact of the new technologies used in diabetes therapy on FOH and different therapeutic possibilities helping patients cope with excessive levels of FOH. We also presented clinical cases of patients with high FOH levels met in clinical practice and discussed methods to better diagnose and assist people with this kind of problem.MethodsWe searched for studies and articles via PubMed using the keywords fear of hypoglycemia, diabetes, and hypoglycemia. From screened documents identified from literature search, 67 articles were included in our review.ResultsWe divided results from literature screening into five parts: fear of hypoglycemia and hypoglycemia definition, risk factors for the FOH, methods of measuring levels of FOH, therapies for the FOH, and modern technologies. We also described clinical examples of abnormal fear of hypoglycemia in patients.ConclusionThe review highlights the importance of taking into consideration fear of hypoglycemia phenomenon in diabetic patients in everyday clinical practice.
