Stimulating knowledge-sharing behaviours through ethical leadership and employee trust in leadership: the moderating role of distributive justice
Authors: Le Phong Ba , Nguyen Dung Thi Nguyet 
Published: May 2022

Purpose
Drawing on social exchange theory, this paper aims to clarify the influences of ethical leadership (EL) on knowledge-sharing (KS) behaviours of employees through the mediating roles of affective- and cognitive-based trust in leadership. This work further offers deeper insight into the moderating mechanism of distributive justice in the EL–KS relationship.

Design/methodology/approach
Structural equation modelling (SEM) is used to investigate the influential degree of EL, aspects of employee trust in leadership and distributive justice on employee behaviours towards tacit and explicit knowledge via data collected from 339 participants in 75 Vietnamese firms.

Findings
The empirical findings reveal that employee trust in leadership positively mediates the relationship between EL and KS behaviours. In particular, distributive justice significantly fosters the impacts of EL on tacit and explicit KS behaviours.

Practical implications
Managers and practitioners should strengthen EL practices to build and maintain employee trust in them for promoting KS behaviours. In addition, research highlights the necessity of establishing distributive justice in organisations to enhance the effect of EL on KS behaviours of employees.

Originality/value
This paper is unique in its attempts to advance the insights on the theory of leadership and knowledge management by investigating the different moderated-mediation mechanisms in the relationship between EL and specific aspects of KS behaviours.
What does it look like? A window into classroom-based critical service learning
Authors: Riley Kathleen , Soslau Elizabeth Gayle 
Published: May 2022

PurposeThis study aims to illustrate Mitchell’s (2008) theory of critical service-learning within elementary and middle school classrooms, looking specifically at classroom events, in which community partners visit classrooms to discuss student-selected social issues.Design/methodology/approachData from teacher interviews, classroom observations, teacher-recorded classroom videos and photos of student artifacts were collected and analyzed. Using deductive analysis, key observable events were identified, in which a teacher and their students navigated opportunities to take a social change orientation, redistribute power, or engage in authentic relationships. Classroom discourse analysis was used to examine these specific events to illustrate what critical service learning looks like in action.FindingsAnalysis revealed how core principles of critical service-learning play out in the classrooms. Two major themes that emerged were students engaging in systemic thinking and students taking on new roles as they operated in classrooms where traditional relationships among teacher, student and content were shifted from a banking model to a problem-posing model.Originality/valueMuch of the research on service learning has been conducted in university, high school or out-of-school settings or analyzes classroom practices based on traditional, individual civic actions. Very little empirical work explores practices in classrooms where teachers facilitate critical service-learning over the course of an entire school year. This study offers an image of the kinds of student thinking that becomes possible in elementary and middle school classrooms enacting critical service learning.
Buyer-supplier dyad on performance and sustainability
Authors: Hao Zirong , Goh Mark , Jiao Jinxia , Liu ChenGuang 
Published: May 2022

PurposeThis paper investigates how the configuration of a supplier’s sustainable operations practices (SOPs) with a high sustainable performance affects a buyer’s organizational performance in the buyer-supplier dyad.Design/methodology/approachThis study first identifies the key SOPs using bibliometric and content analyses. Then, the research hypotheses are proposed using complexity theory and the resource-based view. This study applies fuzzy-set qualitative comparative analysis (fsQCA) on a sample of 74 buyer-supplier dyads in China to explore the configurations of a supplier’s SOPs that may attain a high sustainable performance. An analysis of variance (ANOVA) is performed to test the effects of these configurations on a buyer’s financial and operational performance.FindingsThe empirical findings inform that six configurations of a supplier’s key SOPs lead to a high sustainable performance, and are linked to a buyer’s operational and financial performance. A buyer’s financial performance is highest when its supplier adopts a combination of SOPs corresponding to the defensive, accommodative, and proactive sustainability strategies. A buyer’s operational performance is relatively high when its supplier adopts a combination of SOPs corresponding to the defensive and accommodative sustainability strategies.Originality/valueThis study is the first to draw on complexity theory and the resource-based view as complementary frameworks to analyze how the configuration of a supplier’s SOPs with a high sustainable performance affects a buyer’s organizational performance in the buyer-supplier dyad.
Public procurement during the pandemic: experience of India and China
Authors: Goyal Yugank 
Published: May 2022

Purpose
The paper examines the public procurement experiences of India and China during the Covid-19 pandemic and locates them in a framework it proposes. The paper aims to enrich the knowledge of how public procurement could be strategically used in emergencies.

Design/methodology/approach
For the two countries, the paper sieved through government orders and notifications promulgated during and for the pandemic, examined the prevailing laws and statutes that were invoked and comprehensively scanned online news portals to gather evidence. In addition, the author also engaged with select, relevant people in the sector who offered useful information about ground-level scenario.

Findings
It is found that as compared to China, in India (a) despite the presence of significant flexibilities, (b) there was a little divergence from standard procurement practices, perhaps explained by (c) weaker governance capacity and legitimacy, (c) more allocative (rather than structural) goals of procurement and (d) higher levels of centralization.

Research limitations/implications
The findings of this paper are based entirely on secondary evidence limited to health care as a category of spend. This paper looks at two large countries and not their internal variations in procurement quality. The framework can also be enriched further by drawing additional categories to make the theoretical framework more promising.

Practical implications
The underlying design and motivation of public procurement policies in India need significant changes to make procurement policies responsive to disasters. Also, one can learn decentralization during emergency from the otherwise centralized politics in China.

Originality/value
To the best of the author’s knowledge, this paper is the first attempt to compare pandemic procurement-related policies of the two large countries across the Himalayan border. It also attempts to develop a scale/framework on which emergency procurement in countries can be assessed.

Published: May 2022

AbstractGeneralized pustular psoriasis (GPP) is a life‐threatening condition; however, little is known about the factors that can predict GPP patients manifesting a deteriorating course. To investigate the demographics and clinical features of adult inpatient GPP and propose a prediction model for detecting fatal GPP (fGPP) and GPP requiring intensive care unit admission (iGPP) patients, a nationwide population‐based retrospective cohort study was conducted. The adult inpatients with GPP from January 2007 to December 2020 were assessed. The 800 cases were aged 51.0 years (median [interquartile range, 37.0–64.0]). Overall, 21 iGPP (64.0 years [54.0–77.0]) and 17 fGPP (75.0 years [68.0–77.0]) cases were identified as deteriorating GPP. Renal disease (odds ratio [OR], 7.31), myocardial infarction history (OR, 4.29), liver disease (OR, 2.82), and diabetes mellitus (OR, 2.34) were identified as predictors for iGPP. For fGPP, myocardial infarction history (OR, 5.10) and psoriasis history (OR, 3.13) were established as predictors. A prediction model with scores ranging 0–11 points showed a reliable diagnostic value in detecting deteriorating GPP (area under the curve = 0.75 for iGPP and 0.83 for fGPP). In conclusion, this study provides the clinical features of deteriorating GPP. A prediction model may help physicians to identify patients with deteriorating GPP.
Investissement en santé et état de santé dans les pays de l'UEMOA: entre contribution publique et privée?

Published: May 2022

RésuméL'objectif de ce papier est d'analyser l'effet des investissements en santé sur l'état de santé dans l'UEMOA. A cet effet, un modèle de panel dynamique a été utilisé pour un échantillon de 8 pays couvrant la période 2000 à 2014. L'estimateur LSDV‐Corrigé a été utilisé pour obtenir les résultats sans biais. Les résultats montrent que les dépenses de santé influencent considérablement l'état de santé en améliorant l'espérance de vie à la naissance et en réduisant le taux de mortalité infanto‐juvénile. En outre, les dépenses de santé publiques et privées ont montré une forte association positive avec l'état de santé. Cependant l'influence des dépenses privées de santé est plus importante. Ces résultats impliquent que les dépenses de santé sont indispensables à l'amélioration de l'état de santé dans l'UEMOA. Ainsi, les décideurs publics doivent augmenter les dépenses publiques de santé pour réaliser les objectifs de santé et améliorer le partenariat public‐privé pour la répartition des dépenses de santé.
Gender, socioeconomic status, and COVID‐19 vaccine hesitancy in the US: An intersectionality approach
Authors: Morales Danielle Xiaodan , Beltran Tyler Fox , Morales Stephanie Alexandra 
Published: May 2022

AbstractPrevious research on coronavirus disease 2019 (COVID‐19) vaccine hesitancy lacks a gender perspective, and it is unclear whether gender intersects with socioeconomic status to co‐produce inequalities in people's intent to take vaccines. The current study draws on intersectionality theory and uses data from the 2021 US Household Pulse Survey (n = 50,359). Both bivariate and multivariate statistical analyses were conducted. The results suggest that American women had a higher vaccine hesitancy rate than men. Gender interacts with socioeconomic status to shape people's vaccine hesitancy in a complex way. Specifically, women living in poverty or currently working were more vaccine‐hesitant, while poverty and employment status did not affect men's vaccine hesitancy. However, not having a college education contributed to both women's and men's COVID‐19 vaccine hesitancy. Moreover, women were more worried about the safety of the vaccine, but men's hesitancy tended to be driven by lower perceptions of COVID‐19 dangers and belief in conspiratorial claims.

Published: May 2022

AbstractObjectiveTo assess changes in the prevalence of multidisciplinary cancer consultations (MDCc) over the last decade and examine patient, surgeon, hospital, and neighborhood factors associated with receipt of MDCc among individuals diagnosed with cancer.Data SourceSurveillance, Epidemiology and End Results (SEER)–Medicare data from 2006 to 2016.Study DesignWe used time‐series analysis to assess change in MDCc prevalence from 2007 to 2015. We also conducted multilevel logistic regression with random surgeon‐ and hospital‐level effects to assess associations between patient, surgeon, neighborhood, and health care organization‐level factors and receipt of MDCc during the cancer treatment planning phase, defined as the 2 months following cancer diagnosis.Data Collection/Extraction MethodsWe identified Medicare beneficiaries >65 years of age with surgically resected breast, colorectal (CRC), or non‐small cell lung cancer (NSCLC) stages I–III (n = 103,250).Principal FindingsFrom 2007 to 2015, the prevalence of MDCc increased from 35.0% to 61.2%. Overall, MDCc was most common among patients with breast cancer compared to CRC and NSCLC. Cancer patients who were Black, had comorbidities, had dual Medicare‐Medicaid coverage, were residing in rural areas or in areas with higher Black and Hispanic neighborhood composition were significantly less likely to have received MDCc. Patients receiving surgery at disproportionate payment‐sharing or rural‐designated hospitals had 2% (95% CI: −3.55, 0.58) and 17.6% (95% CI: −21.45, 13.70), respectively, less probability of receiving MDCc. Surgeon‐ and hospital‐level effects accounted for 15% of the variance in receipt of MDCc.ConclusionsThe practice of MDCc has increased over the last decade, but significant geographical and health care organizational barriers continue to impede equitable access to and delivery of quality care across cancer patient populations. Multilevel and multicomponent interventions that target care coordination, health system, and policy changes may enhance equitable access to and receipt of MDCc.

Published: May 2022

AbstractWith the completion of the draft assembly of the giant panda genome sequence, RNA sequencing technology has been widely used in genetic research on giant pandas. We used RNA‐seq to examine black and white hair follicle samples from adult pandas. By comparison with the giant panda genome, 75 963 SNP loci were labeled, 2426 differentially expressed genes (DEGs) were identified, and 2029 new genes were discovered, among which 631 were functionally annotated. A cluster analysis of the DEGs showed that they were mainly related to the Wnt signaling pathway, ECM–receptor interaction, the p53 signaling pathway, and ribosome processing. The enrichment results showed that there were significant differences in the regulatory networks of hair follicles with different colors during the transitional stage of hair follicle resting growth, which may play a regulatory role in melanin synthesis during growth. In conclusion, our results provide new insights and more data support for research on the color formation in giant pandas.

AbstractExamples of photoluminescence (PL) are being reported with increasing frequency in a wide range of organisms from diverse ecosystems. However, the chemical basis of this PL remains poorly defined, and our understanding of its potential ecological function is still superficial. Among mammals, recent analyses have identified free‐base porphyrins as the compounds responsible for the reddish ultraviolet‐induced photoluminescence (UV‐PL) observed in the pelage of springhares and hedgehogs. However, the localization of the pigments within the hair largely remains to be determined. Here, we use photoluminescence multispectral imaging emission and excitation spectroscopy to detect, map, and characterize porphyrinic compounds in skin appendages in situ. We also document new cases of mammalian UV‐PL caused by free‐base porphyrins in distantly related species. Spatial distribution of the UV‐PL is strongly suggestive of an endogenous origin of the porphyrinic compounds. We argue that reddish UV‐PL is predominantly observed in crepuscular and nocturnal mammals because porphyrins are photodegradable. Consequently, this phenomenon may not have a specific function in intra‐ or interspecific communication but rather represents a byproduct of potentially widespread physiological processes.
Kinetics of 5% and 20% albumin: A controlled crossover trial in volunteers
Authors: Zdolsek Markus , Hahn Robert G. 
Published: May 2022

AbstractBackgroundAlbumin for intravenous infusion is marketed in two concentrations, 20% and 5%, but how they compare with regard to plasma volume expansion over time is unclear.MethodsIn a prospective crossover study, 12 volunteers received 3 ml kg−1 of 20% albumin and, on another occasion, 12 ml kg−1 of 5% albumin over 30 min. Hence, equivalent amounts of albumin were given. Blood was collected on 15 occasions over 6 h. Mass balance and volume kinetics were used to estimate the plasma volume expansion and the capillary leakage of albumin and fluid based on measurements of blood hemoglobin, plasma albumin, and the colloid osmotic pressure.ResultsThe greatest plasma volume expansion was 16.0 ± 6.4% (mean ± SD) with 20% albumin and 19.0 ± 5.2% with 5% albumin (p < .03). The volume expansion with 20% albumin corresponded to twice the infused volume. One third of the 5% albumin volume quickly leaked out of the plasma, probably because of the higher colloid osmotic pressure of the volunteer plasma (mean, 24.5 mmHg) than the albumin solution (19.1 mmHg). At 6 h, the capillary leakage amounted to 42 ± 15% and 47 ± 11% of the administered albumin with the 20% and 5% preparations, respectively (p = .28). The corresponding urine outputs were 547 (316–780) ml and 687 (626–1080) ml (median and interquartile range; p = .24).ConclusionThe most important difference between the fluids was a dehydrating effect of 20% albumin when the same albumin mass was administered.
Chronic ethanol consumption plus an atherogenic diet cause metabolic steatohepatitis with advanced liver fibrosis in apolipoprotein E/low‐density lipoprotein receptor double‐knockout mice
Authors: Liu Jinyao , Oba Yumiko , Yamano Seiko 
Published: May 2022

AbstractBackgroundNonalcoholic steatohepatitis is the inflammatory subtype of nonalcoholic fatty liver disease with a high risk of progression to liver fibrosis. We investigated metabolic steatohepatitis with advanced liver fibrosis in apolipoprotein E/low‐density lipoprotein receptor double‐knockout (AL) mice fed a co‐diet of ethanol with a low‐carbohydrate–high‐protein‐high‐fat atherogenic diet (AD) for 16 weeks. We also examined the underlying mechanisms, especially hepatic sympathetic activation, involved in the effects.MethodsWe maintained 12‐week‐old male AL mice on AD and a standard chow diet (SCD) with or without ethanol treatment for 16 weeks. Age‐matched male C57BL/6J mice on SCD without ethanol treatment served as controls. We conducted blood biochemical, histopathological, and fluorescence immunohistochemical, and reverse transcriptase polymerase chain reaction studies.ResultsAL mice showed significant hyperlipidemia. AD induced increased body weight, hepatic steatosis, and hepatic damage; ethanol and the AD co‐diet resulted in hepatic sympathetic activation accompanied by hepatic steatosis, lobular inflammation, bridging fibrosis, and hepatic damage. Hepatic Kupffer cells (KCs) and hepatic stellate cells (HSCs), which showed sympathetic activation, produced 4.4‐ to 9.4‐fold more inflammatory factors (KC and KC‐derived tumor necrosis factor‐α, and chemokine [C‐C motif] ligand 2) and 2.0‐ to 32.0‐fold more fibrosis factors (HSC and HSC‐derived transforming growth factor β1 and collagen 1a1); all p < 0.05 vs. controls.ConclusionsWe created a model of metabolic steatohepatitis with advanced liver fibrosis from coexisting hyperlipidemia and hepatic sympathetic activation in AL mice on a co‐diet of ethanol and AD. KCs and HSCs became the cellular targets of hepatic sympathetic activation, which could play a role in the initiation and progression of metabolic steatohepatitis with advanced liver fibrosis.

Published: May 2022

AbstractBackground and aimsGenomic and transcriptomic findings greatly broaden the biological knowledge regarding substance use. However, systematic convergence and comparison evidence of genome‐wide findings is lacking for substance use. Here, we combined all the genome‐wide findings from both substance use behavior and disorder (SUBD) and identified common and distinguishing genetic factors for different SUBDs.MethodsSystemic literature search for genome‐wide association (GWAS) and RNA‐seq studies of alcohol/nicotine/drug use behavior (partially meets or not reported diagnostic criteria) and alcohol use behavior and disorder (AUBD), nicotine use behavior and disorder (NUBD) and drug use behavior and disorder (DUBD) was performed using PubMed and the GWAS catalog. Drug use was focused upon cannabis, opioid, cocaine and methamphetamine use. GWAS studies required case–control or case/cohort samples. RNA‐seq studies were based on brain tissues. The genes which contained significant single nucleotide polymorphism (P ≤ 1 × 10−6) in GWAS and reported as significant in RNA‐seq studies were extracted. Pathway enrichment was performed by using Metascape. Gene interaction networks were identified by using the Protein Interaction Network Analysis database.ResultsTotal SUBD‐related 2910 genes were extracted from 75 GWAS studies (2 773 889 participants) and 17 RNA‐seq studies. By overlapping the genes and pathways of AUBD, NUBD and DUBD, four shared genes (CACNB2, GRIN2B, PLXDC2 and PKNOX2), four shared pathways [two Gene Ontology (GO) terms of ‘modulation of chemical synaptic transmission’, ‘regulation of trans‐synaptic signaling’, two Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of ‘dopaminergic synapse’, ‘cocaine addiction’] were identified (significantly higher than random, P < 1 × 10−5). The top shared KEGG pathways (Benjamini–Hochberg‐corrected P‐value < 0.05) in the pairwise comparison of AUBD versus DUBD, NUBD versus DUBD, AUBD versus NUBD were ‘Epstein–Barr virus infection’, ‘protein processing in endoplasmic reticulum’ and ‘neuroactive ligand‐receptor interaction’, respectively. We also identified substance‐specific genetic factors: i.e. ADH1B and ALDH2 were unique for AUBD, while CHRNA3 and CHRNA4 were unique for NUBD.ConclusionsThis systematic review identifies the shared and unique genes and pathways for alcohol, nicotine and drug use behaviors and disorders at the genome‐wide level and highlights critical biological processes for the common and distinguishing vulnerability of substance use behaviors and disorders.

Published: May 2022

AbstractWe present a case of a neonate who presented with multiple cutaneous and subcutaneous nodules, which was found to be metastatic embryonal rhabdomyosarcoma. Rhabdomyosarcoma is a soft tissue malignancy that usually occurs in children aged one to five but is rare in neonates. The histopathological analysis and molecular genetics are important in the classification of subtype and in guiding treatment options and informing prognosis.
