Fostering Well‐being through Social Support: The Role of Evangelical Communities in the Lives of Dominican Women of Haitian Descent
Authors: Salusky Ida , Tull Mary , Case Andrew D. , Soto‐Nevarez Arturo 
Published: October 2020

AbstractWomen of Haitian descent living in the Dominican Republic experience oppression due to their gender, ethnicity, and economic status. They also exhibit high rates of participation in evangelical Christian communities, a paradoxical finding given the restricted roles women have traditionally played in these settings. The goals of this study were to explore the perceived benefits of participation in evangelical communities and the setting characteristics that lead to these benefits. The research team interviewed 19 current and former church participants aged 18–59. Thematic analysis revealed three perceived benefits of congregational life. Participants viewed their participation as: (a) an opportunity for personal growth and development; (b) protective against negative social influences; and (c) providing social support in the face of life challenges. In addition, dependable, expected, and reciprocal relational support was a key characteristic of evangelical communities. Findings extend the current understanding of how religious communities enhance well‐being for marginalized women through social support networks. Findings also explore the dialectical nature of settings as both empowering and disempowering. Implications for future interventions are discussed.
Fitness, physical activity, or sedentary patterns? Integrated analysis with obesity surrogates in a large youth sample
Authors: Henriques‐Neto Duarte , B. Júdice Pedro , Peralta Miguel , B. Sardinha Luís 
Published: October 2020

AbstractObjectivePhysical fitness (PF) and physical activity (PA) are inversely associated with body mass index and waist circumference (WC), whereas sedentary time (ST) seems to boost obesity in youth. The aim was to examine the associations of each selected PF test, PA‐related exposures, and specific ST patterns with obesity and determine the most relevant ones, in a large sample of a school‐aged adolescent.MethodsThe sample consisted of 2696 Portuguese youth aged 10 to 18 years. Height, weight, and WC were measured. PA and ST components were measured using accelerometry. PF was evaluated using a battery of tests.ResultsThe Progressive Aerobic Cardiovascular Endurance Run (PACER) and push‐up tests seemed to be the exposures that presented the strongest and more consistent associations with obesity, independent of PA/ST profiles (P < .05). The second exposure of relevance for adolescent obesity level was the breaks in ST with a negative relationship regardless of PA/PF profiles (P < .05). Finally, ST accumulated in periods of <30 minutes, and moderate‐to‐vigorous PA were favorably associated with obesity, independent of ST/PF.ConclusionsIndependent of PA and ST, cardiorespiratory fitness (CRF), measured by PACER, was associated with obesity markers. This may be in part due to the dependence of PACER performance on adiposity. Also, limiting prolonged ST and promoting interruptions in this behavior were associated with obesity. These associations suggest that future research should examine other strategies beyond PA promotion for tackling obesity that consider CRF and breaking ST.
An Imine‐Linked Metal–Organic Framework as a Reactive Oxygen Species Generator

Published: October 2020

AbstractA new metal–organic framework (MOF) with both coordination linkages and covalent linkages is prepared by coordinating CuI with pyrazolate for an aldehyde‐functionalized trinuclear complex, and subsequent imine condensation with p‐phenylenediamine, a reaction typical for covalent organic framework (COF) synthesis. This MOF×COF collaboration yields FDM‐71 with honeycomb layers stacked in eclipsed fashion. After dissociating the CuI‐pyrazolate coordination in FDM‐71, the obtained organic components carry the information of structural defects, and thus vacancy identity (aldehyde‐based unit vacancy and amine‐based unit vacancy) and concentration are definitely resolved. Further to the redox catalytic activity inherited from the complex, FDM‐71 features effective photosensitizing activity. The two functions integrated in one well‐defined structure is demonstrated by its high efficiency in decomposing H2O2 and consequent excitation of O2 to reactive oxygen species.

Published: October 2020

AbstractUsing the bimetallic combination sBu2Mg⋅2 LiOR (R=2‐ethylhexyl) in toluene enables efficient and regioselective Br/Mg exchanges with various dibromo‐arenes and ‐heteroarenes under mild reaction conditions and provides bromo‐substituted magnesium reagents. Assessing the role of Lewis donor additives in these reactions revealed that N,N,N′,N′′,N′′‐pentamethyldiethylenetriamine (PMDTA) finely tunes the regioselectivity of the Br/Mg exchange on dibromo‐pyridines and quinolines. Combining spectroscopic with X‐ray crystallographic studies, light has been shed on the mixed Li/Mg constitution of the organometallic intermediates accomplishing these transformations. These systems reacted effectively with a broad range of electrophiles, including allyl bromides, ketones, aldehydes, and Weinreb amides in good yields.
COVID‐19 and Facebook in Papua New Guinea: Fly River Forum
Authors: Dwyer Peter D. , Minnegal Monica 
Published: October 2020

AbstractThis article examines use of a Papua New Guinea (PNG) Facebook group, Fly River Forum, with reference to the COVID‐19 global pandemic. From about mid‐March 2020, when the PNG Government declared a State of Emergency, to early May, members of that forum shared an intense interest in the pandemic and were deeply concerned with its possible implications for the country. The great majority of COVID‐related posts, and associated comments, combined delivery of relevant information with scepticism about some of that information. Most participants did not take either religious tropes or conspiracy theories as primary sources of comfort or explanation. We argue that Fly River Forum played a positive role in the ways that people engaged with what could have emerged as a health disaster. More generally, geographically focused sites such as this provide a valuable barometer of local opinion and deserve close attention by politicians and policymakers in PNG.

Published: October 2020

AbstractWe report here that macrocyclic H‐bonded pyridone pentamers, containing five properly and convergently spaced electron‐rich O‐atoms that decorate a rigid cavity of 2.85 Å across, exhibit an extraordinarily high yet pH‐independent capacity and selectivity in Cs+ removal. In particular, with [host]=240 μM and [Cs+]=15 μM, a single extraction efficiently removes more than 91% of Cs+ ions from artificial sea water, containing various competitive metal ions at a total concentration of 0.68 M ([total Mn+]/[Cs+]=4.5×104]). To our best knowledge, these pyridone pentamers represent the best small organic molecule‐based extractants that target Cs+ ions.

Published: October 2020

The prevalence of autism spectrum disorder (ASD) is continuously rising worldwide, with remarkable differences in ASD rates being reported across ethnic and socioeconomic groups. We conducted a prospective cohort study to identify the reasons for differences in ASD rates between the Bedouin and Jewish populations in southern Israel. Screening, referral, and diagnosis of toddlers aged 16–36 months were compared between Bedouin and Jewish populations. ASD screening was conducted at 35 randomly selected mother and child health centers (MCHCs) by trained nurses using the Modified Checklist for Autism in Toddlers with follow‐up (M‐CHAT/F) instrument. Toddlers screened positive at the MCHCs were monitored throughout the referral and diagnosis process at a single medical center until a diagnosis was determined by a physician specialist using DSM‐5 criteria. The study cohort comprised 3,343 toddlers (996 Jewish and 2,347 Bedouin). Bedouin toddlers, compared to Jewish toddlers, were less likely to screen positive with M‐CHAT/F (3.0% vs. 3.9%; P = 0.165), were significantly less likely to begin the hospital diagnosis process (HR = 0.38, 95% CI: 0.14–1.08; P = 0.068), and had a higher rates of loss‐to‐follow‐up during the hospital diagnosis process (42.9% vs. 15.6%, respectively; P = 0.001). The results suggest that ethnic‐specific barriers in the diagnosis process of ASD contribute to under‐diagnosis of ASD in the Bedouin population. Facilitating the diagnosis process for Bedouin families will help to identify more children with ASD at earlier ages and consequently close the ethnic gap in ASD rates.Lay SummaryWe followed Bedouin and Jewish toddlers aged 16–36 months from southern Israel through their autism spectrum disorder (ASD) screening referral and diagnosis to identify the reasons for the differences in ASD prevalence between these ethnic groups. Jewish and Bedouin toddlers were equally identified in the ASD screening. However, Bedouin toddlers were less likely to complete the diagnosis process due to higher rates of loss‐to‐follow‐up and slower diagnosis process. Facilitating ASD diagnosis for the Bedouin population will help identifying more toddlers with ASD.

Published: October 2020

AbstractIntroductionPrior Go/NoGo studies have localized specific regions and EEG spectra for which traditional approaches have distinguished between Go and NoGo conditions. A more detailed characterization of the spatial distribution and timing of the synchronization of frequency bands would contribute substantially to the clarification of neural mechanisms that underlie performance of the Go/NoGo task.MethodsThe present study used a machine learning approach to learn the features that distinguish between ERSPs involved in selection and inhibition in a Go/NoGo task. A single‐layer neural network classifier was used to predict task conditions for each subject to characterize ERSPs associated with Go versus NoGo trials.ResultsThe final classifier accurately identified individual task conditions at an overall rate of 92%, estimated by fivefold cross‐validation. The detailed accounting of EEG time–frequency patterns localized to brain regions (i.e., thalamus, pre‐SMA, orbitofrontal cortex, and superior parietal cortex) corroborates and also elaborates upon previous findings from fMRI and EEG studies, and expands the information about EEG power changes in multiple frequency bands (i.e., primarily theta power increase, alpha decreases, and beta increases and decreases) within these regions underlying the selection and inhibition processes engaged in the Go and NoGo trials.ConclusionThis time–frequency‐based classifier extends previous spatiotemporal findings and provides information about neural mechanisms underlying selection and inhibition processes engaged in Go and NoGo trials, respectively. This neural network classifier can be used to assess time–frequency patterns from an individual subject and thus may offer insight into therapeutic uses of neuromodulation in neural dysfunction.
Disordered eating and internalizing symptoms in preadolescence
Authors: Thomas Kai S. , Williams Marc O. , Vanderwert Ross E. 
Published: October 2020

AbstractObjectivesResearch has demonstrated links between disordered eating, anxiety, and depression in adults and adolescents but there is limited research investigating these associations in preadolescence. The current study examined the associations between disordered eating, anxiety, and depression during preadolescence, as well as the role of gender in moderating these associations.MethodTwo hundred and thirteen children (M = 10.3 years; 51.2% male) reported levels of disordered eating (ChEAT) and anxiety and depression symptoms (RCADS‐25).ResultsRegression analyses support an association between disordered eating and both anxiety and depression in preadolescence. Overall, there were no significant differences between boys and girls when the main effect was examined, which differs from research in adolescents.DiscussionThese findings highlight the importance of early detection for disordered eating behaviors and attitudes, as well as anxiety and depression in both boys and girls during preadolescence. Longitudinal research examining these associations is vital to help understand the trajectories of these problems, but also the gender differences in disordered eating that emerge during adolescence. Transdiagnostic interventions targeting several co‐occurring problems, such as disordered eating, anxiety, and depression might be effective for preventing the development of eating disorders in the long term.
Biodiversity and extinction accounting for sustainable development: A systematic literature review and future research directions
Authors: Roberts Lee , Hassan Abeer , Elamer Ahmed , Nandy Monomita 
Published: October 2020

AbstractThis paper seeks to present the first systematic literature review (SLR) on biodiversity and species extinction accounting publications. This strand of research is gaining increased attention due to emerging scientific evidence that finds a relationship between the human destruction of biodiversity and the recent Covid‐19 crisis, causing profound economic and health impacts. This justifies the need for an SLR of 40 articles from 2013 to 2020. Descriptive results show research contributions peaked in 2018 with the most publications appearing in the Accounting, Auditing & Accountability Journal. Results show legitimacy theory is the most applied theoretical framework with global studies and developed country specific research receiving the greatest attention. In addition, content analysis is identified as the preferred research methodology. Additionally, through synthesising and analysing literature, we provide potential opportunities for future research that is underexplored. This paper will provide a valuable study for academics, policymakers and practitioners pursuing research in this field.

Published: October 2020

AbstractMyocardial bridges are anatomical entities characterized by myocardium covering segments of coronary arteries. In some patients, the presence of a myocardial bridge is benign and is only incidentally found on autopsy. In other patients, however, myocardial bridges can lead to compression of the coronary artery during systolic contraction and delayed diastolic relaxation, resulting in myocardial ischemia. This ischemia in turn can lead to myocardial infarction, ventricular arrhythmias and sudden cardiac death. Myocardial bridges have also been linked to an increased incidence of atherosclerosis, which has been attributed to increased shear stress and the presence of vasoactive factors. Other studies however, demonstrated the protective roles of myocardial bridges. In this study, using systematic review and a meta‐analytical approach we investigate the prevalence and morphology of myocardial bridges in both clinical imaging and cadaveric dissections. We also discuss the pathophysiology, clinical significance, and management of these anatomical entities.
The effect of regulatory focus on customer citizenship behavior in a virtual brand community: The role of online self‐presentation and community identification

Published: October 2020

AbstractCustomer citizenship behavior (CCB) in virtual brand communities is a topic of increasing importance in marketing management research. This type of behavior plays a critical role in the improvement of enterprises' marketing capabilities. In this study, we draw on regulatory focus theory—along with the perspectives of self‐presentation and regulatory fit in relation to social identity—to construct and test a model that investigates both the main effects of regulatory foci (promotion and prevention) and the indirect effects of online self‐presentation and community identification on CCB. The empirical results based on our online survey between 310 individual members of an well‐known online‐community in China demonstrate: (1) a promotion focus exerts a positive influence on CCB while a prevention focus exerts a negative impact; (2) the desire for online self‐presentation mediates the association between regulatory foci and CCB; and (3) community identification moderates the relationship between regulatory foci and the desire for online self‐presentation, as well as the mediation effect. These results have substantial implications for studying CCB within virtual brand communities.

Published: October 2020

AbstractBiomass particle separation is challenging in the pharmaceutical industry because of the smallness and lightness of such particles. Centrifugation is applied conventionally for batch separation. However, imposing multiple wash steps in order to eliminate culture residues and the high risk of extrinsic contamination hamper batch techniques. In this research, minihydrocyclones were introduced to provide a better solution for the mentioned limitations in continuous processes. Numerical separation of methylotrophic yeast from fermentation broth was carried out in three hydrocyclones with different lengths, and the most efficient one was examined experimentally. Three various feed flow rates and seven feed concentrations were evaluated. The concentration of biomass suspension in the product was raised to 20 %.

Published: October 2020

AbstractPerforming a heterogeneous catalysis with proteins is still a challenge. Herein, we demonstrate the importance of cross‐linked crystals for sulfoxide oxidation by an artificial enzyme. The biohybrid consists of the insertion of an iron complex into a NikA protein crystal. The heterogeneous catalysts displays a better efficiency‐with higher reaction kinetics, a better stability and expand the substrate scope compared to its solution counterpart. Designing crystalline artificial enzymes represents a good alternative to soluble or supported enzymes for the future of synthetic biology.

Published: October 2020

AbstractLight regulation of drug molecules has gained growing interest in biochemical and pharmacological research in recent years. In addition, a serious need for novel molecular targets of antibiotics has emerged presently. Herein, the development of a photocontrollable, azobenzene‐based antibiotic precursor towards tryptophan synthase (TS), an essential metabolic multienzyme complex in bacteria, is presented. The compound exhibited moderately strong inhibition of TS in its E configuration and five times lower inhibition strength in its Z configuration. A combination of biochemical, crystallographic, and computational analyses was used to characterize the inhibition mode of this compound. Remarkably, binding of the inhibitor to a hitherto‐unconsidered cavity results in an unproductive conformation of TS leading to noncompetitive inhibition of tryptophan production. In conclusion, we created a promising lead compound for combatting bacterial diseases, which targets an essential metabolic enzyme, and whose inhibition strength can be controlled with light.

Published: October 2020

AbstractAlthough 1,2,4,5‐tetrazines or s‐tetrazines have been known in the literature for more than a century, their coordination chemistry has become increasingly popular in recent years due to their unique redox activity, multiple binding sites and their various applications. The electron‐poor character of the ring and stabilization of the radical anion through all four nitrogen atoms in their metal complexes provide new aspects in molecular magnetism towards the synthesis of new high performing Single Molecule Magnets (SMMs). The scope of this review is to examine the role of s‐tetrazine radical ligands in transition metal and lanthanide based SMMs and provide a critical overview of the progress thus far in this field. As well, general synthetic routes and new insights for the preparation of s‐tetrazines are discussed, along with their redox activity and applications in various fields. Concluding remarks along with the limitations and perspectives of these ligands are discussed.
