Published: June 2022

AbstractJapanese farmers who grow Oriental persimmon, Diospyros kaki Thunb. (Ericales: Ebenaceae), occasionally introduce Apis mellifera L. (Hymenoptera: Apidae) hives into their orchards during the flowering season, mainly because cultivars such as ‘Fuyu’ require pollination for stable fruit set. However, wild pollinators might serve this function. Thus, we aimed at identifying the most important pollinators of D. kaki in Japan by surveying visitation frequency across ten prefectures and pollination efficiency. The predominant flower visitors were Bombus ardens ​ardens Smith (Hymenoptera: Apidae) and A. mellifera, with similar pollination efficiencies. The estimated threshold number of pollen grains for fruit set of D. kaki ‘Fuyu’ was 27, which was comparable to the number deposited by a single visit of either species, meaning one visit of these dominant visitors probably induces fruit set. However, more pollen grains deposited by multiple visits further ensured fruit set. To achieve > 80% fruit set, more than about 70 pollen grains were needed. These results indicate that several visits by the bees would be sufficient for fruit set of D. kaki ‘Fuyu’.

Published: June 2022

AbstractThis article reports on original research investigating the pivotal role that teachers play in student engagement, using a tri-dimensional framework. This framework identifies how teachers’ pedagogical choices impact student engagement in ways that influence students’ external behaviours, internal emotions and internal cognitions. A questionnaire was developed to explore secondary teachers’ (n = 223) perceptions of pedagogies that support students’ behavioural, emotional and cognitive engagement in the classroom. Findings revealed that female participants placed higher importance on pedagogies that support students’ cognitive and behavioural engagement, and participants with leadership roles placed higher importance on pedagogies that support students’ cognitive and emotional engagement. Also emerging from the research was a negative correlation between the importance teachers placed on pedagogies that support cognitive and behavioural engagement and their school’s ICSEA value (the measure of socio-educational advantage in Australian schools). Overall, results support the tri-dimensional framework of student engagement utilised in this study and provide a robust framework for future research to further explore teachers’ pedagogical choices and how these choices impact student engagement.
On quasi norm attaining operators between Banach spaces

Published: June 2022

AbstractWe provide a characterization of the Radon–Nikodým property for a Banach spaceYin terms of the denseness of bounded linear operators intoYwhich attain their norm in a weak sense, which complement the one given by Bourgain and Huff in the 1970s for domain spaces. To this end, we introduce the following notion: an operator$$T:X \longrightarrow Y$$T:X⟶Ybetween the Banach spacesXandYis quasi norm attaining if there is a sequence$$(x_n)$$(xn)of norm one elements inXsuch that$$(Tx_n)$$(Txn)converges to some$$u\in Y$$u∈Ywith$$\Vert u\Vert =\Vert T\Vert $$‖u‖=‖T‖. We prove that strong Radon–Nikodým operators can be approximated by quasi norm attaining operators, a result which does not hold for norm attaining operators. It shows that this new notion of quasi norm attainment allows us to characterize the Radon–Nikodým property in terms of denseness of quasi norm attaining operators for both domain and range spaces, which in the case of norm attaining operators, was only valid for domain spaces due to the celebrated counterexample by Gowers in 1990. A number of other related results are also included in the paper: we give some positive results on the denseness of norm attaining nonlinear maps, characterize both finite dimensionality and reflexivity in terms of quasi norm attaining operators, discuss conditions such that quasi norm attaining operators are actually norm attaining, study the relation with the norm attainment of the adjoint operator and, finally, present some stability results.

AbstractDiabetes is an urgent health issue characterized by ethnic and regional variations, and is inseparable from the different dietary habits. It is worthy to note that the incidence of diabetes in Bai nationality has been reported to be much lower than Han in China. As a daily vegetable of Bai, the phytochemical and antidiabetic study ofOttelia acuminatavar.acuminatahad not been carried out. In this study, 41 metabolites with diverse diarylheptanoid (six new ones, Otteacumienes A–F), flavone, sesquiterpenoid, coumarin, lignan, polyacetylene, and alkaloid skeletons were characterized fromO. acuminatavar.acuminata. Among them, the racemic nature of3was characterized by chiral resolution and calculated ECD methods. The biological study revealed diarylheptanoids showed significantα-glucosidase inhibitory activities with5as the most effective one (60-fold stronger than acarbose). Molecular docking studies indicated that these structures have different binding cavities with acarbose. This study demonstrated thatO. acuminatavar.acuminatamight correlated with the low incidence diabetes of Bai and the diarylheptanoids may have potential therapeutic value for diabetes mellitus.Graphical Abstract

AbstractThe use of nano-gypsum in low doses can be an innovative method to mitigate salinity-sodicity effects and enhance spinach growth in saline-sodic soil. We evaluated nano-gypsum in four low doses of 960, 480, 240, and 120 kg ha−1, in addition to the control and the recommended conventional gypsum dose (~ 30 t ha−1), in a randomized complete pot experiment. The pots of soil were incubated in a laboratory for 2 months and leached 5 times for another 2 months. Then, spinach was grown in the soil for 60 days. The nano-gypsum dose of 240 kg ha−1 with leaching was the best at improving the soil and spinach growth characteristics compared with the other doses and both control and conventional gypsum rate. Moreover, it was considered the critical nano-gypsum threshold rate. Compared to control after soil leaching, the critical rate increased the water-stable aggregate index and reduced bulk density by 57.39% and 16.30%, respectively; accordingly, the saturated hydraulic conductivity increased up to 2.34 times. Improved hydraulic conductivity led to a decrease in exchangeable Na ratio by 91% and reduced both soil salinity and pH by 83% and 1 unit, respectively. These great improvements in the soil properties favored the spinach growth indicators, which increased leaf area index, root hair index, and fresh yield by 2.20, 4.41, and 1.29 times, respectively, when compared to the recommended conventional gypsum rate. Accordingly, nano-gypsum in low doses is considered an innovative alternative to high doses of conventional gypsum to mitigate salinity-sodicity effects and enhance spinach growth in saline-sodic soil.

Published: June 2022

AbstractThe assessment of environmental identity (EID) in terms of connectedness to nature, eco-friendly behaviour (EFB) and closeness to nature variables is the central focus of this study. The elaborated conceptual model recommends that closeness to nature, connectedness to nature and EFBs related to education, economy and recycling are potential predictors of EID. The sample consists of 518 college students studying in different teacher education programmes. Confirmatory factor analysis was used to evaluate the constructive validity of the scales for each of the measurement models. The theoretical path analysis model was created by considering existing literature. In the present study, the EFBs of the participants had a significant and moderate effect on their EID. Findings confirmed that environmental education behaviours and recycling behaviours had a positive and low effect on EFBs. The results showed that connectedness to nature and closeness to nature had a positive and medium effect on EFB. Promotion of EID sense in pre-service teachers will increase their students’ EID. Finally, advanced degree curricula in environmental protection and nature can be designed and implemented based on target group information.
A diffractive and decolonising reading methodology for education research
Authors: Bellingham Robin A. 
Published: June 2022

AbstractFor white settler researchers aiming to contribute to the work of decolonising education, actively seeking ways to disturb and destabilise long-held onto-epistemological assumptions associated with colonial modernity is important. In this article I investigate how these disturbances might occur in a diffractive and decolonising reading methodology. I outline two prior diffractive reading experiences that drew on decolonial theory and Barad’s diffraction theory: A situated inquiry of the Great Barrier Reef as a pedagogical agent; and a reading of Australian teacher education policy through military imaginaries. In this article I read these prior diffractive reading experiences through one another, attending to further methodological patterns. I identify two connected methods of defamiliarisation that are generative for destabilising colonising ways of knowing, norms and thinking in education. These are: Bringing ostensibly different phenomena together in diffractive relations with one another; and reading difference in the spirit of companionship, that is, in an orientation to learning from difference rather than to master difference. I suggest that if education continues to rely on and wield the same modern critical tools that support colonial-capitalist systems it will be unable to recognise, address and reimagine the continued violence of these systems.
SOLUTIONS OF THE tt*-TODA EQUATIONS AND QUANTUM COHOMOLOGY OF MINUSCULE FLAG MANIFOLDS
Authors: KANEKO YOSHIKI 
Published: June 2022

AbstractWe relate the quantum cohomology of minuscule flag manifolds to the tt*-Toda equations, a special case of the topological–antitopological fusion equations which were introduced by Cecotti and Vafa in their study of supersymmetric quantum field theories. To do this, we combine the Lie-theoretic treatment of the tt*-Toda equations of Guest–Ho with the Lie-theoretic description of the quantum cohomology of minuscule flag manifolds from Chaput–Manivel–Perrin and Golyshev–Manivel.

AbstractLet R be a Cohen–Macaulay local K-algebra or a standard graded K-algebra over a field K with a canonical module
$\omega _R$
. The trace of
$\omega _R$
is the ideal
$\operatorname {tr}(\omega _R)$
of R which is the sum of those ideals
$\varphi (\omega _R)$
with
${\varphi \in \operatorname {Hom}_R(\omega _R,R)}$
. The smallest number s for which there exist
$\varphi _1, \ldots , \varphi _s \in \operatorname {Hom}_R(\omega _R,R)$
with
$\operatorname {tr}(\omega _R)=\varphi _1(\omega _R) + \cdots + \varphi _s(\omega _R)$
is called the Teter number of R. We say that R is of Teter type if
$s = 1$
. It is shown that R is not of Teter type if R is generically Gorenstein. In the present paper, we focus especially on zero-dimensional graded and monomial K-algebras and present various classes of such algebras which are of Teter type.
Soviet National Autonomy in the 1920s: The Dilemmas of Ukraine’s Jewish Population
Authors: Raspe Jonathan 
Published: June 2022

AbstractThis article examines the Soviet system of territorial autonomy by studying its impact on the Jewish population of Soviet Ukraine in the 1920s. While the new Soviet state created national republics, districts, and village councils for its non-Russian nationalities, Ukraine’s Jewish population was faced with a dilemma: Ukrainian Jews lived predominantly in cities, but urban space could not be claimed for Jewish territorial autonomy because the Soviet government hoped that peasant immigration would produce a Ukrainian working class. Without an autonomous status, many Jews felt threatened by the increasing influx of Ukrainians and the spread of Ukrainian-language institutions. Offered as a consolation prize, the Soviet Yiddishization initiative failed to cater to the needs of many Jews who preferred the Russian language as a means for social mobility. Attempts to resettle urban Jews in compact agricultural colonies suitable for territorial autonomy never reached the necessary scale. In conclusion, this article argues that the incompatibility of Soviet territorial autonomy with Ukrainian Jewish needs anticipated the Soviet state’s inability to accommodate the increasingly urban, heterogeneous, transnational, multilingual, and mobile society that emerged in the postwar Soviet Union.

Abstract
Ankyrin (ANK) repeat proteins are coded by tandem occurrences of patterns with around 33 amino acids. They often mediate protein–protein interactions in a diversity of biological systems. These proteins have an elongated non-globular shape and often display complex folding mechanisms. This work investigates the energy landscape of representative proteins of this class made up of 3, 4 and 6 ANK repeats using the energy-landscape visualisation method (ELViM). By combining biased and unbiased coarse-grained molecular dynamics AWSEM simulations that sample conformations along the folding trajectories with the ELViM structure-based phase space, one finds a three-dimensional representation of the globally funnelled energy surface. In this representation, it is possible to delineate distinct folding pathways. We show that ELViMs can project, in a natural way, the intricacies of the highly dimensional energy landscapes encoded by the highly symmetric ankyrin repeat proteins into useful low-dimensional representations. These projections can discriminate between multiplicities of specific parallel folding mechanisms that otherwise can be hidden in oversimplified depictions.

AbstractSe is an indispensable trace element for the human body, and telomere length is considered a marker of biological ageing. Previous studies have shown that dietary Se intake is associated with telomere length. However, the relationship between Se intake and telomere length in patients with diabetes has not been well studied. Therefore, this study aimed to investigate the relationship between dietary Se intake and telomere length in patients with diabetes. We extracted 878 participants with diabetes from the National Health and Nutrition Examination Survey database for 1990–2002. Dietary Se intake was assessed using the 24 h dietary recall method, and telomere length was measured using quantitative PCR. Generalised linear models were constructed to assess the relationship between dietary Se intake and telomere length. After controlling for the confounders, 1 μg increase in dietary Se intake in female patients with diabetes, and telomere length increased by 1·84 base pairs (β = 1·84 (95 % CI: 0·15, 3·53)), there was a line relationship between dietary Se intake and telomere length in female patients with diabetes and telomere length increased with increasing dietary Se intake within the range of 0–250 μg. The study demonstrates that dietary Se intake is significantly associated with telomere length only in the female population with diabetes in the USA. However, further prospective studies are required to confirm this finding.
An Empirical Assessment of Empirical Corporate Finance
Authors: Coles Jeffrey L. , Li Zhichuan F. 
Published: June 2022

AbstractWe empirically evaluate 20 prominent contributions across a broad range of areas in the empirical corporate finance literature. We assemble the necessary data and apply a single, simple econometric method, the connected-groups approach of Abowd et al. to appraise the extent to which prevailing empirical specifications explain variation of the dependent variable, differ in composition of fit arising from various classes of independent variables, and exhibit resistance to omitted variable bias and other endogeneity problems. We assess empirical performance across a wide spectrum of areas in corporate finance and indicate varying research opportunities for empiricists and theorists.

Published: June 2022

AbstractBackgroundThe COVID-19 pandemic has been associated with increased levels of depression and anxiety with implications for the use of antidepressant medications.MethodsThe incident rate of antidepressant fills before and during the COVID-19 pandemic were compared using interrupted time-series analysis followed by comprehensive sensitivity analyses on data derived from electronic medical records from a large health management organization providing nationwide services to 14% of the Israeli population. The dataset covered the period from 1 January 2013 to 1 February 2021, with 1 March 2020 onwards defined as the period of the COVID-19 pandemic. Forecasting analysis was implemented to test the effect of the vaccine roll-out and easing of social restrictions on antidepressant use.ResultsThe sample consisted of 852 233 persons with a total antidepressant incident fill count of 139 535.4 (total cumulative rate per 100 000 = 16 372.91, 95% CI 16 287.19–16 459.01). We calculated the proportion of antidepressant prescription fills for the COVID-19 period, and the counterfactual proportion for the same period, assuming COVID-19 had not occurred. The difference in these proportions was significant [Cohen's h = 10−3 (0.16), 95% CI 10−3 ( − 0.71 to 1.03)]. The pandemic was associated with a significant increase in the slope of the incident rate of antidepressant fills (slope change = 0.01, 95% CI 0.00–0.03; p = 0.04) and a monthly increase of 2% compared to the counterfactual (the estimated rate assuming no pandemic occurred). The increased rate was more pronounced in women, and was not modified by lockdown on/off periods, socioeconomic or SARS-CoV-2 status. The rate of observed antidepressant fills was similar to that forecasted under the assumption of ongoing COVID-19 distress.ConclusionThese findings underscore the toll of the pandemic on mental health and inform mental health policy and service delivery during and after implementing COVID-19 attenuation strategies.
Modes of relating to the new ICTs among older internet users: a qualitative approach
Authors: Coelho Ana Rita 
Published: June 2022

AbstractOlder people have increasingly been using the new information and communication technologies (ICTs), namely the internet. Seeking to contribute with substantive information on their digital inclusion, this paper focuses on the adoption and use of ICTs by older adults, highlighting their experiences and considering their plurality. Taking a qualitative approach, the core goal of the empirical research underlying this paper was to understand what mechanisms and modalities configure the relationship of older internet users with the new ICTs. With that objective in mind, interviews were conducted with 20 internet users over the age of 60. Those interviews, which included a biographical element, were subjected to multi-categorical analysis. Results suggest a typology of modes of relating to the new ICTs among older internet users that reflects different trajectories, practices, skills, significances and impacts. The analysis shows how life trajectories and differentiated uses are reflected in equally differentiated impacts for older adults, contributing to their quality of life in different ways and to different degrees. Digital skills play a fundamental role in enhancing or limiting those effects. The results of this research help break down the stereotypes associated with the older generations and may have relevant implications for the design of digital inclusion policies and initiatives.
A place outside the pandemic? An ethnographic study of live music events at St Gallen's cultural venue Palace during the COVID-19 crisis
Authors: Gligorijevic Jelena 
Published: June 2022

AbstractThe multiple impacts of COVID-19 on the music-culture industry have been duly discussed in a variety of public discourses, academic and otherwise. However, there is still a dearth of studies that investigate alternative face-to-face practices of live music performance and organisation during the pandemic's significant constraints on social behaviour. The present work aims to fill this gap by offering an anthropological angle on live music practices during COVID-19. It specifically draws on fieldwork that I could carry out in the autumn of 2020 at a live music venue – ‘Palace’ in the Swiss city of St Gallen – owing to a ‘liberal’ handling of the COVID-19 crisis by the St Gallen authorities. This article documents accordingly the challenges and adjustments that Palace had to undergo during pandemic times from the perspectives of producers, musicians and audiences alike. The primary focus here is on exploring changes in the venue's management, programming, audience composition and especially the musical-aesthetic experience of the venue's pandemic-compliant gigs. Finally, the article draws on the musings of my interlocutors as to whether Palace was in their experience a place outside the pandemic, to tackle the larger question of how COVID-19 has affected people's perceptions of live gigs and urban nightlife more generally.
An Automated Scanning Transmission Electron Microscope Guided by Sparse Data Analytics

Abstract
Artificial intelligence (AI) promises to reshape scientific inquiry and enable breakthrough discoveries in areas such as energy storage, quantum computing, and biomedicine. Scanning transmission electron microscopy (STEM), a cornerstone of the study of chemical and materials systems, stands to benefit greatly from AI-driven automation. However, present barriers to low-level instrument control, as well as generalizable and interpretable feature detection, make truly automated microscopy impractical. Here, we discuss the design of a closed-loop instrument control platform guided by emerging sparse data analytics. We hypothesize that a centralized controller, informed by machine learning combining limited a priori knowledge and task-based discrimination, could drive on-the-fly experimental decision-making. This platform may unlock practical, automated analysis of a variety of material features, enabling new high-throughput and statistical studies.
