Legitimacy, stratification, and internationalization in global higher education: the case of the International Association of Universities
Authors: Zapp Mike , Jungblut Jens , Ramirez Francisco O. 
Published: October 2020

AbstractThe International Association of Universities (IAU) is the only inclusive global university association, its membership barriers are low, yet few universities are members despite considerable benefits. What determines membership in this long-standing international university alliance? Reviewing recent trends toward a more networked, stratified and internationalized global higher education field, we argue that universities with a greater need for legitimation and those ‘born’ into a global era are more likely to become members of an inclusive international network like the IAU. Thus, we expect lower status and younger universities to be more likely to join. We apply regression models to test hypotheses implied by these arguments. Our findings are consistent with these hypotheses, even after controlling for other factors. We discuss these findings using neo-institutional arguments about legitimacy and imprinted logics and suggest potential analytical avenues for further research.

AbstractLow cost and green fabrication of high-performance electrocatalysts with earth-abundant resources for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are crucial for the large-scale application of rechargeable Zn–air batteries (ZABs). In this work, our density functional theory calculations on the electrocatalyst suggest that the rational construction of interfacial structure can induce local charge redistribution, improve the electronic conductivity and enhance the catalyst stability. In order to realize such a structure, we spatially immobilize heterogeneous CoS/CoO nanocrystals onto N-doped graphene to synthesize a bifunctional electrocatalyst (CoS/CoO@NGNs). The optimization of the composition, interfacial structure and conductivity of the electrocatalyst is conducted to achieve bifunctional catalytic activity and deliver outstanding efficiency and stability for both ORR and OER. The aqueous ZAB with the as-prepared CoS/CoO@NGNs cathode displays a high maximum power density of 137.8 mW cm−2, a specific capacity of 723.9 mAh g−1 and excellent cycling stability (continuous operating for 100 h) with a high round-trip efficiency. In addition, the assembled quasi-solid-state ZAB also exhibits outstanding mechanical flexibility besides high battery performances, showing great potential for applications in flexible and wearable electronic devices.
Characterizing the hypergraph-of-entity and the structural impact of its extensions
Authors: Devezas José , Nunes Sérgio 
Published: October 2020

AbstractThe hypergraph-of-entity is a joint representation model for terms, entities and their relations, used as an indexing approach in entity-oriented search. In this work, we characterize the structure of the hypergraph, from a microscopic and macroscopic scale, as well as over time with an increasing number of documents. We use a random walk based approach to estimate shortest distances and node sampling to estimate clustering coefficients. We also propose the calculation of a general mixed hypergraph density measure based on the corresponding bipartite mixed graph. We analyze these statistics for the hypergraph-of-entity, finding that hyperedge-based node degrees are distributed as a power law, while node-based node degrees and hyperedge cardinalities are log-normally distributed. We also find that most statistics tend to converge after an initial period of accentuated growth in the number of documents. We then repeat the analysis over three extensions—materialized throughsynonym,context, andtf_binhyperedges—in order to assess their structural impact in the hypergraph. Finally, we focus on the application-specific aspects of the hypergraph-of-entity, in the domain of information retrieval. We analyze the correlation between the retrieval effectiveness and the structural features of the representation model, proposing ranking and anomaly indicators, as useful guides for modifying or extending the hypergraph-of-entity.

Published: October 2020

Abstract
Background
Fragility fractures are common in care home residents but established tools have not been tested in this population. Aim:To identify the most practicable tool for use.

Methods

Design
Multicentre prospective observational cohort pilot study. Setting: 18 care homes in Boston, UK. Assessments: fragility risk score at baseline with FRAX, QFractureScore, Garvan nomogram, body mass index and TUGT for each participant. Outcomes: falls, fractures, combined falls & fractures. Follow-up; 12 months.

Results
217/618 (35%) residents in the 18 care homes were enrolled. 147 (68%) had mental capacity,70 (32%) did not. There were 325 falls and 10 fractures in participants during the study. At the same time there were 1671 falls and 103 fractures in residents not participating in the study. Multiple regression analyses showed that only age had a statistically significant association with falls (χ2(1) = 5.7775, p = 0.0162), fractures (χ2(1) = 4.7269, p = 0.0297) and combined falls & fractures (χ2(1) = 4.7269, p = 0.0297). C-statistics were: falls; FRAX 0.544, BMI 0.610, QFractureScore 0.554, Garvan nomogram 0.579, TUGT 0.656, fractures; FRAX 0.655, BMI 0.708, QFractureScore 0.736, Garvan nomogram 0.712, TUGT 0.590, combined falls and fractures, c-statistics were same as for fractures. Fifty-four participants (25%) died during follow-up. Charlson comorbidity index predicted mortality, R2 = 0.021 (p = 0.034).

Conclusions
QFractureScore, BMI and Garvan nomogram were good predictors of fractures and combined falls and fractures Only age had statistically significant association with the outcomes. No tool was good predictor of falls.
The plate spacing of sea ice
Authors: Maus Sönke 
Published: October 2020

AbstractColumnar sea ice grows with an interface of tiny parallel ice plates, the distance of which is known as plate spacing. While it has been proposed as a fundamental microstructure scale of sea ice, the physics behind its formation has not been fully understood. Here the problem is analysed on the basis of morphological stability theory to propose a model that results in a physically consistent prediction of the relationship between the plate spacinga0and growth velocityV. The relationship may be divided into two regimes. In the diffusive regime, forVabove ≈2 × 10−4cm s−1one findsa0~V−2/3to first order. In the convective regime, the extent of diffusive boundary layer is controlled by solutal convection near the interface, which leads to the proportionalitya0~V−1/3. From a comparison to observations it is evident that the plate spacing is predictable over 5 orders of magnitude in the growth velocity, covering the range from fast laboratory ice growth to slow accretion at the bottom of marine ice shelves. The predictability opens new paths towards concise modelling of marine and sea-ice microstructure and physical properties.
COVID-19 and the Sacrificial International Order
Authors: Barnett Michael 
Published: October 2020

AbstractThis essay uses COVID-19 to illuminate the sacrificial practices of the liberal international order as woven through the concepts of humanitarian governance, moral economy, triage, and sacrifice. The concept of a sacrificial international order calls attention to how all international orders have their share of sacrifices—and this includes liberal international orders. International orders can be distinguished by the selection mechanisms used to identify the sacrifices and the meanings attached to them. I call attention to how liberal international orders often rely on markets as a selection mechanism and interpret these deaths as part of progress. Following critical contributions to the study of neoliberalism that show how markets shape the ethics of “giving life” and “letting die,” I illuminate these processes through four concepts: humanitarian governance and the claim that the highest moral principle is saving lives and relieving suffering; moral economy that regulates who has access to basic subsistence goods during periods of crisis; triage, which considers how to prioritize whose lives are valued; and whether all deaths count as sacrifices or whether they are better understood as “those who can be killed.” I conclude by discussing how COVID-19 conjures hierarchies of humanity ignored by the liberal international order and challenges the discipline to consider the sacrifices in world order.

Published: October 2020

AbstractBackgroundNasal obstruction when lying down is a common complaint in patients with chronic nasal obstruction, but rhinomanometry is typically performed in the sitting position. This study aimed to analyse whether adding rhinomanometry in a supine position is a useful examination.MethodA total of 41 patients with chronic nasal obstruction underwent rhinomanometry and acoustic rhinometry, sitting and supine, before and after decongestion, as well as an over-night polygraphy.ResultsTotal airway resistance was measurable in a supine position in 48 per cent (14 of 29) of the patients with total airway resistance of equal to or less than 0.3 Pa/cm3/second when sitting and in none (0 of 12) of the patients with total nasal airway resistance of more than 0.3 Pa/cm3/second when sitting. After decongestion, this increased to 83 per cent and 58 per cent, respectively.ConclusionIncreased nasal resistance when sitting predicts nasal breathing problems when supine. Rhinomanometry in a supine position should be performed to diagnose upper airway collapse when supine.
Transacting brains: testing an actor–partner model of frontal EEG activity in mother–infant dyads
Authors: Krzeczkowski John E. , Van Lieshout Ryan J. , Schmidt Louis A. 
Published: October 2020

AbstractStudies have long observed the bidirectional nature of mother–infant relationships. While behavioral studies have shown that mothers high in social avoidance tendencies can influence the development of these traits in their offspring, the neurophysiological mechanisms underlying this phenomenon, and the role that the infants play, are not well understood. Here we acquired frontal electroencephalogram asymmetry (FA) data simultaneously in 40 mother–infant dyads (Mage mother = 31.6 years; Mage infant = 9 months). Using an actor–partner interdependence model, we examined whether mother (or infant) resting-state FA predicted infant (or mother) FA during two subsequent emotion-eliciting conditions (happy and fear). Maternal social approach versus avoidance traits were assessed as moderators to examine the impact of maternal characteristics on these mother–infant FA relations. In dyads led by mothers with high social avoidance/low social approach characteristics, maternal resting-state FA predicted infant FA during both emotion-eliciting conditions. We did not observe any effects of infant FA on mothers. Therefore, we speculate that individual differences in FA patterns might be a putative brain mechanism through which socially avoidant mothers transfer affective/behavioral information to their infants.
Plant-based dietary practices in Canada: examining definitions, prevalence and correlates of animal source food exclusions using nationally representative data from the 2015 Canadian Community Health Survey–Nutrition

Published: October 2020

AbstractObjective:While plant-based dietary practices (PBDPs) have been recommended to improve both population health and environmental sustainability outcomes, no nationally representative Canadian studies have described the prevalence or correlates of excluding animal source foods. The current study therefore: (1) created operationalised definitions of PBDPs based on animal source food exclusions to estimate the prevalence of Canadians who adhere to PBDPs and (2) examined key correlates of PBDPs.Design:Population representative, cross-sectional data were from the 2015 Canadian Community Health Survey–Nutrition. Respondents’ PBDPs were categorised as: (1) vegan (excluded red meat, poultry, fish, eggs and dairy); (2) vegetarian (excluded red meat, poultry and fish); (3) pescatarian (excluded red meat and poultry) and (4) red meat excluder (excluded red meat). Descriptive statistics and multivariable regression analyses were used to examine the prevalence and correlates of these PBDP categories.Setting:All ten provinces in Canada.Participants:Canadians aged 2 years and above (n 20 477).Results:In 2015, approximately 5 % of Canadians reported adhering to any PBDP (all categories combined) with the majority (2·8 %) categorised as a red meat excluder, 1·3 % as vegetarian, 0·7 % as pescatarian and 0·3 % as vegan. South Asian cultural identity (OR 19·70 (95 % CI 9·53, 40·69)) and higher educational attainment (OR 1·97 (95 % CI 1·02, 3·80)) were significantly associated with reporting a vegetarian/vegan PBDP.Conclusions:Despite growing public discourse around PBDPs, only 5 % of Canadians reported PBDPs in 2015. Understanding the social and cultural factors that influence PBDPs is valuable for informing future strategies to promote environmentally sustainable dietary practices.

AbstractObjective:To evaluate associations between selected dietary concerns and eating practices and determine the association of these concerns/practices with demographic and socio-economic characteristics in a population from a large Brazilian city.Design:Population-based cross-sectional study. We investigated concerns regarding salt intake, the use of highly processed seasoning and the custom of reading the Na content on food labels. We also analysed concerns regarding the use of pesticides on food products and the practice of consuming organic foods. These variables were analysed according to sex, age group, schooling and income. Multivariate Poisson regression analysis was performed for the estimation of prevalence ratios.Setting:Campinas, state of São Paulo, Brazil.Participants:The representative sample consisted of 1710 adults and seniors.Results:A total 62·3 % of the population were concerned with salt intake, 34·7 % did not use highly processed seasoning and 10·6 % checked the Na content on food labels; 27·5 % were concerned with pesticides and 26·5 % consumed organic foods. The practices analysed were associated with the respective concerns. Women and seniors had a better profile, except for reading Na content in both groups and the consumption of organic foods among seniors. The frequency of checking the Na content and consuming organic foods increased with the level of schooling. The higher income group had a better profile, except for concern with salt intake.Conclusions:Considerable social differences were found regarding the dietary practices, and the practices were associated with concerns. The present findings underscore the need for different dietary counseling strategies targeting specific groups.

AbstractBreeding for resistance to biotic stress and higher yield is a continuous process. Thus, the identification of desirable parents with good combining ability and nature of gene action for the target trait is of utmost importance. Hence, in this present investigation, 10 lines and three testers of Okra were crossed in line × tester mating design to generate 30 testcross progenies and their evaluation along with parents and check in a randomized complete block design with three replications. To depict the true picture of genetic variation among the parental genotypes, molecular diversity analysis was also carried out using genomic-simple sequence repeats before crossing to ascertain that sufficient variability is present among the parents. The molecular analysis grouped the parental genotypes into four clusters (I–IV). The analysis of variance revealed that all the treatments were significant for most of the traits. The combining ability analysis suggested Pusa A-4 as the best general combiner for earliness, Pusa Bhindi-5 for high yield, and DOV-92 for fruit length, plant height, yield per plant, and coefficient of infection for Yellow Vein Mosaic Virus Disease resistance. Similarly, the specific combining ability analysis suggested that the cross combinations DOV-92 × Pusa Bhindi-5 followed by DOV-92 × Pusa A-4 and DOV-92 × Pusa Sawani exhibit high economic heterosis for yield per plant as well as for disease resistance. Finally, estimation of the degree of dominance and predictability ratio was also worked out which indicated the prevalence of non-additive gene action for most of the traits pointing towards sufficient scope for heterosis breeding in Okra.

AbstractStress sensing is the basis of human-machine interface, biomedical engineering, and mechanical structure detection systems. Stress sensing based on mechanoluminescence (ML) shows significant advantages of distributed detection and remote response to mechanical stimuli and is thus expected to be a key technology of next-generation tactile sensors and stress recorders. However, the instantaneous photon emission in ML materials generally requires real-time recording with a photodetector, thus limiting their application fields to real-time stress sensing. In this paper, we report a force-induced charge carrier storage (FICS) effect in deep-trap ML materials, which enables storage of the applied mechanical energy in deep traps and then release of the stored energy as photon emission under thermal stimulation. The FICS effect was confirmed in five ML materials with piezoelectric structures, efficient emission centres and deep trap distributions, and its mechanism was investigated through detailed spectroscopic characterizations. Furthermore, we demonstrated three applications of the FICS effect in electronic signature recording, falling point monitoring and vehicle collision recording, which exhibited outstanding advantages of distributed recording, long-term storage, and no need for a continuous power supply. The FICS effect reported in this paper provides not only a breakthrough for ML materials in the field of stress recording but also a new idea for developing mechanical energy storage and conversion systems.

Published: October 2020

AbstractHere we present a transgender male adolescent with an androgen receptor-positive serous borderline ovarian tumour in the setting of testosterone treatment for medical gender transition. To our knowledge, this is the second report of borderline tumour in a transgender individual and the first in an adolescent, an age group in which borderline tumours are extremely rare. We discuss the specific considerations of treating ovarian tumours in the transgender male population, the incompletely understood role of androgens in the genesis of ovarian epithelial neoplasia, and an emphasis on assessing cancer risk in transgender patients based on patient anatomy.

AbstractBackgroundWe examined the association between active and passive smoking and lung cancer risk and the population attributable fraction (PAF) of lung cancer due to active smoking, in the Norwegian Women and Cancer Study, a nationally representative prospective cohort study.MethodsWe followed 142,508 women, aged 31–70 years, who completed a baseline questionnaire between 1991 and 2007, through linkages to national registries through December 2015. We used Cox proportional hazards models, to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). We calculated PAF to indicate what proportion of lung cancer cases could have been prevented in the absence of smoking.ResultsDuring the more than 2.3 million person-years of observation, we ascertained 1507 lung cancer cases. Compared with never smokers, current (HR 13.88, 95% CI 10.18–18.91) smokers had significantly increased risk of lung cancer. Female never smokers exposed to passive smoking had a 1.3-fold (HR 1.34, 95% CI 0.89–2.01) non- significantly increased risk of lung cancer, compared with never smokers. The PAF of lung cancer was 85.3% (95% CI 80.0–89.2).ConclusionMore than 8 in 10 lung cancer cases could have been avoided in Norway, if the women did not smoke.

Published: October 2020

AbstractA novel SARS-related coronavirus (SARS-CoV-2) has recently emerged as a serious pathogen that causes high morbidity and substantial mortality. However, the mechanisms by which SARS-CoV-2 evades host immunity remain poorly understood. Here, we identified SARS-CoV-2 membrane glycoprotein M as a negative regulator of the innate immune response. We found that the M protein interacted with the central adaptor protein MAVS in the innate immune response pathways. This interaction impaired MAVS aggregation and its recruitment of downstream TRAF3, TBK1, and IRF3, leading to attenuation of the innate antiviral response. Our findings reveal a mechanism by which SARS-CoV-2 evades the innate immune response and suggest that the M protein of SARS-CoV-2 is a potential target for the development of SARS-CoV-2 interventions.

AbstractSARS-CoV-2 is a betacoronavirus virus responsible for the COVID-19 pandemic. Here, we determine the X-ray crystal structure of a potent neutralizing monoclonal antibody, CV30, isolated from a patient infected with SARS-CoV-2, in complex with the receptor binding domain. The structure reveals that CV30 binds to an epitope that overlaps with the human ACE2 receptor binding motif providing a structural basis for its neutralization. CV30 also induces shedding of the S1 subunit, indicating an additional mechanism of neutralization. A germline reversion of CV30 results in a substantial reduction in both binding affinity and neutralization potential indicating the minimal somatic mutation is needed for potently neutralizing antibodies against SARS-CoV-2.
