Authors: Wu Mengying , Wang Rongsong , Estay Christophe , Shen Wei 
Published: September 2022

PurposeThe purpose of this study is to explore the U-shaped relationship between ambidextrous leadership and employee silence by examining power distance orientation as a boundary condition and role stress and relational energy as mediators.Design/methodology/approachThe authors tested the theoretical model with 212 matched samples collected across three-wave-data from 21 companies and branches in China.FindingsResults revealed that ambidextrous leadership showed a U-shaped relationship with employee silence through role stress and relational energy. Moreover, the authors found that the curvilinear relationship was more significant for employees higher in power distance orientation.Practical implicationsOrganizations should be aware of the negative side of ambidextrous leadership as well as its stimulation on employee silence. The leaders should pay more attention to subordinates and judge whether they are under too much stress, as well as treat employees more cautiously in both work and non-work situations.Originality/valueThis study provides a first step to the understanding of curvilinear influence of ambidextrous leadership through investigating the mediating effects of role stress and relational energy, and integrating the moderating role of power distance orientation in the process.
Students' perspectives on using e-learning applications and technology during the COVID-19 pandemic in Indonesian higher education
Authors: Candra Sevenpri , Jeselin Florensia Sarlin 
Published: September 2022

Purpose
The e-learning-based approach is critical in keeping the wheels of education turning in the face of the COVID-19 epidemic. In this scenario, analyzing the implementation of the e-learning system is required to properly grasp the needs. The purpose of this paper is to demonstrate the relationship between technical system quality, information quality, service quality, educational system quality, support system quality, learner quality, instructor quality, perceived satisfaction, perceived usefulness, e-learning system use and benefits.

Design/methodology/approach
This study was carried out by giving online questionnaires to students attending private institutions in Indonesia. A total of 593 students participated in the study and provided responses. The structural equation model, which is supported by the program WarpPLS7.0, is used to analyze the data.

Findings
Maintaining the quality of the technological system, the information system, the learners and the educational system can help achieve the goal of increasing perceived utility. In the meanwhile, factors such as inadequate service quality, educational system quality, support system quality and teacher quality can all pose challenges to perceived levels of satisfaction. To get the most out of e-learning apps, users' expectations about how fun, useful and easy to use they are need to be met.

Research limitations/implications
This study was carried out in the midst of the COVID-19 epidemic with a restricted number of participants from Indonesian institutions of higher education. This research has the potential to be expanded into a variety of different types of higher education in the future.

Practical implications
The main thing that will determine whether an e-learning system model works is the quality of the learners.

Originality/value
The institution should think about changing the material offered in the e-learning system to make it easier for students to grasp by describing the current material and providing digital handouts of lecturers' explanations. This study expanded the e-learning system success model and applied it to the evaluation of e-learning deployment in Indonesian higher education. This study will improve student comprehension of the e-learning model and contribute to the body of knowledge about e-learning applications and technology.

Authors: Labib Nader L. , Zahran Fouad , Youssef Mohamed Adel , Mazrouaa Azza M. , Mohamed Manal Gamal 
Published: September 2022

Purpose
This study aims to extend the pot life without altering the qualities and performance of the coating, which is important to increase when manufacturing polyurethane coatings.

Design/methodology/approach
An acrylic polyol from a mixture of different monomers of hydroxypropyl methacrylate, methacrylic acid, 2-ethylhexyl acrylate, methyl methacrylate and n-butyl methacrylate was prepared with different ratios of 2,4-pentanedione as a pot life extender. The reaction takes place in presence of di-tert-butyl peroxide as initiator with samples (T1–T7). The physical properties of prepared acrylic polyol were characterized. Then, coating polyurethane varnish was prepared from the prepared acrylic polyol with an aliphatic polyisocyanate in a 1:1 equivalent ratio of OH:NCO at room temperature, in presence of paint thinner (diluents/solvent) and dibutyltin dilaurate as a catalyst to give samples (T1C–T7C). This coating was evaluated via Fourier-transform infrared spectroscopy, drying time, hardness and gloss, distinctness of image and reflected image quality.

Findings
The coating has a prolonged pot life while still maintaining the other qualities, thanks to the greater 2,4-pentanedione content.

Originality/value
It is desired to have a paint which has a satisfactory pot life, short curing time and reduces many drawbacks such as inefficient working and deterioration of the paint before application.
How do accounts pass? A discussion of Vollmer’s “Accounting for tacit coordination”
Authors: Palermo Tommaso 
Published: September 2022

Purpose
Building on the notes prepared for a roundtable organized by qualitative research in accounting & management (QRAM) about the paper titled “Accounting for tacit coordination: The passing of accounts and the broader case for accounting theory” (Vollmer, 2019), this paper aims to extend our understanding of “tacit coordination towards the passing of accounts” and its implications for research on accounting as a social practice.

Design/methodology/approach
Building on a selective review of previous studies of accounting “in action” and one illustrative vignette, this paper teases out specific aspects of Vollmer’s argument, which is much broader and ambitious in nature. The aim is to go deeper on one issue – “tacit coordination towards the passing of accounts” and the role of (accounting) practitioners as “stewards of silence” – to encourage further work that unpacks the dynamics and tensions that occur when practitioners seek to tacitly coordinate towards the passing of accounts.

Findings
This paper shows how our understanding of the relationship between “tacit coordination” and the “passing of accounts” can be enriched by examining how (accounting) practitioners deal with pressures towards explication. To this end, this paper develops three propositions, which focus on how organizational status, organizational complexity and temporal dynamics may affect the extent to which (accounting) practitioners are able to tacitly coordinate towards the passing of accounts.

Practical implications
The three propositions presented in this paper can be used in future studies to further explore the dynamics of tacit coordination towards the passing of accounts and therefore contribute to a more fine-grained illustration of some of the ideas presented in the paper by Vollmer (2019).

Originality/value
This paper sketches the contours of an approach that has the potential to make some of the ambitious ideas presented in Vollmer’s paper more actionable in future studies.

Authors: Silva Cristiane Aparecida da , Rosa Fabricia Silva da 
Published: September 2022

PurposeThe purpose of the article is to analyze the influence of output control, autonomous motivation and controlled motivation on task performance of public servants at home office owing to the COVID-19 pandemic.Design/methodology/approachA survey was conducted based on the perception of 236 public servants, and structural equation modeling (SEM) technique was used for data analysis.FindingsBoth autonomous motivation and output control are positively and significantly related to task performance.Research limitations/implicationsThe present study expands the literature with information about individual performance and management control, which can be related to the control, motivation and task performance of public servants at home office in a pandemic context.Practical implicationsThe results could offer a basis for understanding how managers can deal with the challenges while at home office. They can also provide managers with information that they can use to build management strategies to foster the performance of public servants at home office.Social implicationsHome office can decrease commuting to a central workplace, alleviate traffic problems and reduce car pollution. It also allows for business continuity in the face of storms and pandemics.Originality/valueMost studies about home office, COVID-19 and task performance have addressed personal, professional and organizational characteristics. However, little is known about the analysis of combinations of the following constructs: output control, autonomous and controlled motivations, and how both affect task performance of public servants.
Differential effects of vegetation and climate on termite diversity and damage

Published: September 2022

Abstract

Species diversity shapes ecosystem services. Despite the advantages that this relationship has for pest management, few studies have investigated the links between infrastructure damage (i.e. the percentage amount of infrastructures infested by termites), species richness and the environment. Moreover, it is not clear that which proportion of species richness (total/functional‐dominant/common/rare) contributes most to infrastructure damage.

We correlated termite species richness with termite infestation throughout 83 cities in Zhejiang Province, eastern China. Species were classified according to whether or not they fed on wood, and based upon their distributional range, whether they were common or rare. We analysed the relative importance and the direct/indirect effects of climate, vegetation, anthropogenic activities, and the species richness of four functional categories of termites on the damage levels of eight infrastructure types in populated (i.e. urban and rural building, green space and sea wall) and remote areas (i.e. ancient building, large‐old tree, agroforest and reservoir dam).

Common species favoured populated areas, whereas rare species favoured remote areas. Common species, with preferences for deciduous vegetation, caused more damage to the infrastructures of populated areas. Rare species, with preferences for evergreen vegetation, caused more damage in remote areas. Reforestation project which emphasized evergreen trees increased the number of rare species but reduced the number of common species. Elevation and drought risk were positively correlated with rare species richness but neutrally with common species richness.

Structural equation models showed that vegetation predominantly influenced infrastructure damage in populated areas via altering common species richness, whereas climate predominantly and directly influenced infrastructure damage in remote areas. Notably, elevation and drought risk were positively correlated with infrastructure damage especially in remote areas.

Synthesis and applications. Termites cause global economic losses of 15–40 billion dollars per year. Our study reveals that managing city forests and green space, for example increasing the proportion of evergreen trees, is a sustainable means of suppressing common termites and thereby reducing infrastructure damage in populated areas. Conservation strategies, supported by regular inspections, will become increasingly important as climate change not only threatens the survival of less harmful rare species, but also increases infrastructure damage in remote areas.
Stressful, isolated, yet diverse: Green roofs have rich microbiomes that are not dominated by oligotrophic taxa
Authors: Hénault Antoine , Heim Amy , Brisson Jacques , Dagenais Danielle , De Bellis Tonia , Chagnon Pierre‐Luc 
Published: September 2022

AbstractGreen roofs are unique ecosystems combining two major community assembly filters, namely stress and spatial isolation. As such, they represent an interesting model ecosystem in community ecology. In this study, we characterized the microbiome structure on 19 green roofs and 5 urban parks as a benchmark comparison (i.e. non‐isolated, non‐stressful habitats). Green roofs were not species depauperate, showing similar α‐diversity compared to surrounding parks. We also did not find an overrepresentation of bacterial phyla typically recognized as oligotrophs, which calls into question the notion of green roofs as highly stressful habitats for bacteria, and/or the conservatism of nutritional ecophysiology at the phylum level. The geographical position of a roof, or its degree of spatial isolation (assessed through its height and area) were not important predictors of microbiome diversity and structure, suggesting that dispersal limitations impose little constraints on green roof microbiome assembly. Finally, key microbial groups (e.g. archaeal nitrifiers, Actinobacteria) were much less frequent and/or abundant on green roofs, which may have important implications for nutrient cycling and urban biogeochemistry. More work will be required to phenotype the microorganisms overrepresented on green roofs and specifically measure key soil processes in these unique urban ecosystems.

Published: September 2022

AbstractAimTo explore the relationship between the season of birth and the prevalence of recurrent or chronic rhinitis (rhinitis).MethodsThe medical records of consecutive 17‐year‐old conscripts to the Israeli army were reviewed. We compared the prevalence of rhinitis between children born during different seasons. Multivariate analysis was performed with additional variables.ResultsThe prevalence of rhinitis among the 1.1 million recruits was 7.1% in males and 5.3% in females. The association between birth season and the prevalence of rhinitis was highly significant (p < 0.001 for both genders). Spring was the birth season with the highest prevalence of rhinitis (7.4% in males and 5.5% in females). Males born in the winter and females born in the autumn had the lowest prevalence of rhinitis (6.7%, and 5.2% respectively). There was an increased odds ratio for rhinitis among those with a body mass index above 25, higher cognitive score and maternal birth country out of Israel or Africa.ConclusionsThere was an increased risk of rhinitis among young Israeli adults who were born in the spring, were overweight and had a higher cognitive‐score. Family planning to avoid a spring birth and preventing overweight may reduce the risk of chronic rhinitis.
A 9‐gene prognostic signature for kidney renal clear cell carcinoma overall survival based on co‐expression and regression analyses

Published: September 2022

AbstractThis research attempted to screen potential signatures associated with KIRC progression and overall survival by weighted gene co‐expression network analysis (WGCNA) and Cox regression. The KIRC‐associated mRNA expression and clinical data were accessed from The Cancer Genome Atlas (TCGA) database. Differentially expressed genes (DEGs) were screened by differential analysis. A co‐expression network was constructed by “WGCNA”. Based on WGCNA module, GO and KEGG analyses were performed. Protein–protein interaction (PPI) network was constructed. Prognostic signatures were screened by Lasso‐Cox regression. Prognostic model was evaluated by Receiver Operating Characteristic (ROC) and Kaplan‐Meier (K‐M) curves. Multivariate Cox and nomogram were introduced to examine whether risk score could be an independent marker. qRT‐PCR was introduced to determine expression of 9 hub genes in KIRC clinical tumor tissues and adjacent tissues, respectively. Genes in the green module were highly associated with clinical status, and green module genes were significantly enriched in mitotic nuclear division, cell cycle, and p53 signaling pathway. Twenty‐six candidates were subsequently screened out from the green module. Next, a 9‐gene prognostic model (DLGAP5, NUF2, TOP2A, RRM2, HJURP, PLK1, AURKB, KIF18A, CCNB2) was constructed. The predicting ability of the model was optimal. Some cancer‐related signaling pathways were differently activated between two risk score groups. Additionally, under‐expression of some signature genes (AURKB, CCNB2, PLK1, RRM2, TOP2A) was associated with better survival rate for KIRC patients. Meanwhile, all 9 hub genes were substantially overexpressed in KIRC patients. A KIRC prognostic signature was screened in this study, contributing valuable findings to KIRC biomarker development.
Hypoxic glioma‐derived extracellular vesicles harboring MicroRNA‐10b‐5p enhance M2 polarization of macrophages to promote the development of glioma

Published: September 2022

AbstractIntroductionThe delivery of biomolecules by tumor cell‐secreted extracellular vesicles (EVs) is linked to the development of glioma. Here, the present study was implemented to explore the functional significance of hypoxic glioma cell‐derived EVs carrying microRNA‐10b‐5 (miR‐10b‐5p) on glioma with the involvement of polarization of M2 macrophages.MethodsEVs were isolated from hypoxia‐stimulated glioma cells, and their role in polarization of M2 macrophages was studied by co‐culturing with macrophages. miR‐10b‐5p expression in glioma tissues, glioma‐derived EVs, and macrophages co‐cultured with EVs was characterized. Interaction among miR‐10b‐5p, NEDD4L, and PIK3CA was analyzed. The macrophages or glioma cells were transfected with overexpressing plasmid or shRNA to study the effects of miR‐10b‐5p/NEDD4L/PIK3CA on M2 macrophage polarization, and glioma cell proliferation, migration, and invasion in vitro and in vivo.ResultsPromotive role of hypoxia‐stimulated glioma‐derived EVs in macrophage M2 polarization was confirmed. Elevation of miR‐10b‐5p occurred in glioma tissues, glioma‐derived EVs and macrophages co‐cultured with EVs, and stimulated M2 polarization of macrophages. NEDD4L was a target gene of miR‐10b‐5p. Overexpression of NEDD4L could inhibit PI3K/AKT pathway through increase in ubiquitination and degradation of PIK3CA. Hypoxic glioma‐derived EVs harboring upregulated miR‐10b‐5p triggered an M2 phenotype in macrophages as well as enhanced aggressive tumor biology of glioma cells via inhibition of PIK3CA/PI3K/AKT pathway by targeting NEDD4L.ConclusionsIn summary, miR‐10b‐5p delivered by hypoxic glioma‐derived EVs accelerated macrophages M2 polarization to promote the progression of glioma via NEDD4L/PIK3CA/PI3K/AKT axis.

Published: September 2022

AbstractAimThe aim of this work was to assess the relationship between pelvic pain and rectal prolapse both before prolapse surgery and in the long term after ventral mesh rectopexy (VMR).MethodPatients undergoing VMR between 2004 and 2017 were contacted. Outcomes including the severity of pelvic pain were recorded using a numeric rating scale.ResultsFour hundred and seventy eight of the 749 patients (64%) were successfully contacted. Of these, 39% reported pre‐existing pelvic pain prior to VMR (group A) and 61% were pain free (group B). The median follow‐up time was 8.0 years (interquartile range 5.0–10.0 years). Symptoms of obstructed defaecation were significantly more common (p = 0.002) in group A (91/187, 49%) than in group B (101/291, 35%). In contrast, faecal incontinence was more common (p = 0.007) in group B (75/291, 26%) than in group A (29/187, 15%). In group A, 76% showed improvement in pelvic pain after VMR: 61% were pain free and 39% had partial improvement in their pre‐existing pelvic pain. Patients with persistent pelvic pain were younger (p = 0.01) and more likely to have revisional surgery after VMR (p = 0.0003), but there was no relation to the indication for surgery (p = 0.59). In group B, 15% reported de novo pelvic pain after VMR, and this was more common in women under 50 years old (p = 0.001), when obstructed defaecation was the indication (p = 0.03), in mesh erosion (p = <0.05) and when associated with revisional surgery (p = 0.005).ConclusionPelvic pain is common (39%) in patients undergoing prolapse surgery, and VMR improves this pain in most patients (76%). However, a significant number of patients fail to improve (12%), experience worsening of pain (12%) or develop de novo pelvic pain (15%).
