Servant leadership and employee productivity: a mediating and moderating role
Authors: Sudarmo  , Suhartanti Pratiwi Dwi , Prasetyanto Wahyu Eko 
Published: May 2021

PurposeThis study aims to determine the relationship between servant leadership, innovation self-efficacy, corporate work culture and employee productivity in mediating and moderating role.Design/methodology/approachThe research sample was 72 supervisors and 576 employees from 72 food and beverage small and medium enterprises (SMEs) in three major cities in Indonesia. SPSS and AMOS were used to test the research hypothesis using the hierarchical regression analysis test.FindingsThe results show that there was a positive and significant effect between servant leadership on innovation self-efficacy and employee productivity. Innovation self-efficacy mediates the relationship between servant leadership and employee productivity. Corporate work culture moderated the relationship between innovation self-efficacy and employee productivity.Research limitations/implicationsFuture research with larger samples are needed to determine the relationship between servant leadership, innovation self-efficacy, corporate work culture and employee productivity more clearly not only on food and beverage SMEs but also on other industries. Future research needs to be carried out using experimental and longitudinal research designs.Practical implicationsThere are three important practical implications based on the findings of this study. First, the results of the study provide new ideas for SME managers on how to increase the productivity of their employees, by using servant leadership which is known to be the main driver for innovation self-efficacy behavior. Second, the mediating role of innovation self-efficacy requires managers to build employee self-efficacy behavior, share more power with employees and make employees more involved in decision-making, which in turn can increase employee confidence and motivation, and their productivity. Finally, managers must realize the need to create a productive work culture in the company, by taking various actions, such as giving rewards to productive employees, making clear regulations on the company regarding working hours and company targets, and must pay attention and respect the employee's views and opinions to improve employee identification of their leaders.Originality/valueThis is the first study to build and examine the direct and indirect relationship (mediating and moderating role) between servant leadership, innovation self-efficacy, corporate work culture and employee productivity in food and beverage SMEs.

Published: May 2021

PurposeAdopting efficient marketing strategies is a challenging task in a competitive market place involving complex marketing planning, techniques and mechanisms to identify the best course of action under these circumstances and finding optimal solutions or stable outcomes. Decisions and strategies of competitors in the market influence the selection of the appropriate marketing strategy. The main purpose of this paper is to develop a mathematical methodology based on the game theory approach for planning optimal marketing-mix strategies in dynamic competitive markets, taking into account strategic foresight and interaction effects.Design/methodology/approachThe game theory approach, as a decision-making tool in conflict situations, is suggested for planning and adopting optimal marketing strategy. The main intellectual attraction of the game theory is essentially a question of how to act in gaming situations against highly rational opponents A kind of static, finite and non-cooperative game analytics approach has been developed for this issue, and the proposed model has been implemented to design optimal marketing strategies for two top brands of the automotive parts market in Iran.FindingsThe findings of this study show that the optimal marketing-mix strategy for brand A is pricing and for brand B is the product strategy.Practical implicationsGame theory and the Nash equilibrium model can provide a practical approach to find and adopt the right strategy, know competitors' movements and strategies and get more profit.Originality/valueThe integration of the game theory approach into the marketing mix framework has been adopted as a generalized model for marketing strategy planning and analysis as well as to resolve some shortcomings of the marketing mix framework. The Nash equilibrium model has been used to analyze the results. The incorporation of game theory into marketing models has the potential to enrich the scope of marketing modeling.
Reporting practices in situations of conflicting institutional logics: the case of a German federal authority
Authors: Gisch Celina , Hirsch Bernhard , Lindermüller David 
Published: May 2021

Purpose
This study aims to understand how reporting practices act as drivers of change in situations of conflicting institutional logics in a public sector organisation.

Design/methodology/approach
The findings are based on a case study of a German federal authority, where management accounting reports were introduced as part of a “new” managerial logic of control.

Findings
In the case organisation, management accounting reports were intended to change the behaviour of executives but were still guided by an “old” logic of justification. Nevertheless, over time, the addressees of the reports used the reports and reconciled different logics. This documents a process from decoupling to compromising and, finally, reconciling different institutional logics.

Originality/value
By examining the practices of management accounting reporting, this study elaborates the tensions placed on individuals by conflicting institutional logics and provides insights into how organisational practices are used to handle and reconcile conflicting logics in a public sector organisation. Therefore, this paper contributes to the discussion on how organisational practices act as drivers of organisational change.
Determinants of the performance of Moroccan banks
Authors: Derbali Abdelkader 
Published: May 2021

PurposeThe economic and financial literature dealing with the subject of bank profitability has often been based in the measurement of banking results on three main indicators: ROA, ROE and MIN. This article aims to determine and analyze the different determinants that influence bank profitability and to identify the impact of these determinants on the profitability of Moroccan banks.Design/methodology/approachFor this purpose, a fixed individual effect model was adopted for the case of six Moroccan banks during the period of study from 1997 to 2018. The authors carried out their estimates at three levels according to three categories of profitability factors: bank factors, factors of the banking system and macroeconomic factors.FindingsThe empirical findings show that Moroccan banks react on their size to boost their performance, which further explains the continued expansion of Moroccan banking networks. The authors confirm that Moroccan banks have not yet reached a level of size that will be detrimental to their performance. Therefore, the authors can conclude that the big Moroccan banks do not follow the concept of economy of scale. The effects of the variation in the level of economic growth as well as the evolution of the level of inflation on the performance of Moroccan banks are not significant.Originality/valueThe authors’ findings and results have some important originality and value. Primarily, these results would consist of better helping the State, bankers, and bank managers to better understand the various determinants of bank profitability. The results may also help to better examine the effect of each factor, whether internal or external, on banks' bottom line.

Published: May 2021

Purpose
The purpose of this paper is to investigate the impact of Islamic Shariah compliance on customer satisfaction through the mediating effect of service quality in Islamic banking services.

Design/methodology/approach
A total of 334 completed and usable questionnaires were collected from customers of Islamic banks in Bangladesh to test the hypotheses. The data were analyzed using SmartPLS 3.

Findings
The findings of this study indicate that Islamic Shariah compliance has a positive and significant influence on service quality and customer satisfaction of Islamic banking services. The research findings also indicate that service quality partially mediate the relationship between Islamic Shariah compliance and customer satisfaction of Islamic banking services.

Research limitations/implications
This study only emphasized on the Islamic banking services of Bangladesh and thus findings of the present study may not be applicable to other service areas.

Practical implications
The implications of the research are twofold. First, a strong standardized effect of Islamic Shariah compliance on service quality implies that customers are very sensitive to Shariah compliance related to Islamic banking services. Next, maintaining service quality is another crucial aspect to satisfy customers of Islamic banks. Quality of services will only be materialized when all the promises made by the bank function accordingly. Therefore, strategy makers of Islamic banks should assess the customer service quality and satisfaction regularly to improve the overall service experience of customers.

Originality/value
Limited studies have been conducted to investigate the mediating effect of service quality on the relationship between Shariah compliance and customer satisfaction in Islamic banking services. This study provides valuable insights to Islamic bank to integrate the service quality along with Shariah compliance to enhance customer satisfaction.

The ethical problems of continuing with placebo controlled vaccine trials and alternative clinical trial protocols are discussed as well as concrete vaccination issues such as the splitting of doses, the delaying of the second dose, the immunization with two different vaccine types and the need of vaccinating seropositive subjects. Strategies to increase vaccine acceptance in the population are shortly mentioned.
Planning for the next pandemic: Reflections on the early phase of the AustralianCOVID‐19 public health response from the emergency department
Authors: Govindasamy Laksmi Sakura , Hsiao Kai Hsun , Foong Lai Heng , Judkins Simon 
Published: April 2021

AbstractEDs play a crucial role as frontline health services throughout public health emergencies, including pandemics. The strength of the Australian public health response to coronavirus disease 2019 (COVID‐19) has mitigated the impact of the pandemic on clinical services, but there has still been a substantial impact on EDs and the health system. We revisit major events and lessons from the first wave of COVID‐19 in Australia to consider the implications and avenues for system‐level improvements for future pandemic and public health emergency response for EDs. Notwithstanding, the remarkable efforts of healthcare workers across the health system, COVID‐19 has uncovered structural and planning challenges and highlighted weaknesses and strengths of the Australian federation. In anticipating future pandemics and other public health threats, particularly in the face of climate change, hard‐won lessons from the COVID‐19 response should be incorporated in future planning, policies, practice and advocacy.
The Problem is not Covid‐19, it's the Model! Industrial Agriculture and Migrant Farm Labour in the EU
Authors: Molinero‐Gerbeau Yoan 
Published: May 2021

SummaryThe Covid‐19 crisis has shed light on two structural problems that affect a large part of the European model of industrial fruit and vegetable production, mainly in Spain and Italy: excessive dependence on foreign labour and the appalling social and working conditions of these migrant workers. Despite the current intense debates that have arisen on this topic, this is not a new issue but a chronic problem, which has characterised much of the agricultural production in the EU for over two decades. In order to understand how and why this point has been reached, a historical review of the evolution of the primary sector, mainly in southern Europe, and its link to migration, is carried out to ascertain whether the pandemic has aggravated the terrible consequences, mainly for migrant workers, of a socially unsustainable model. The aim is to lay the foundations for a debate on the direction in which European agriculture is heading, and which contributions, such as reforming the CAP and conditioning its funds to decent working conditions can be made towards building a fairer and more sustainable model over time.
The role of HR attributions in the HRM – Outcome relationship: Introduction to the special issue
Authors: Sanders Karin , Guest David , Rodrigues Ricardo 
Published: April 2021

AbstractHuman resource (HR) process research seeks to explain the relationship between HR practices and employee outcomes and organisational performance. This body of research examines the HR implementation process, particularly the role of line managers, and the employees' HR sense‐making process. Among these processes, one promising line of research explores the antecedents and consequences of employees' HR attributions or beliefs about why their organisation implements specific HR practices. However, research on these HR attributions has been rather limited leading to this special issue to advance our knowledge of this field. In this Introduction to the special issue we review the current ‘state‐of‐the‐art’ and highlight the research questions which we invited contributors to address. We outline how the articles advance our knowledge and help to promote a future research agenda.

Published: May 2021

AbstractBackgroundOsimertinib is a third‐generation epidermal growth factor receptor‐tyrosine kinase inhibitor (EGFR‐TKI) approved for the treatment of patients with EGFR‐mutant non‐small cell lung cancer (NSCLC). However, the mechanisms of acquired drug resistance to osimertinib have not as yet been clarified. Exosomes and microRNAs (miRNAs) are involved in carcinogenesis and drug resistance in human cancers.MethodsWe used previously established osimertinib‐resistant HCC827 (HCC827‐OR) and PC‐9 (PC‐9‐OR) cells. We evaluated the profiles of exosomal miRNA associated with resistance to osimertinib in EGFR‐mutant NSCLC cells.ResultsEpithelial–mesenchymal transition (EMT) phenomenon was observed in HCC827‐OR and PC‐9‐OR cells. Microarray and quantitative reverse transcription‐polymerase chain reaction analysis revealed that miR‐210‐3p was co‐upregulated in exosomes isolated from HCC827‐OR and PC‐9‐OR cells compared with those isolated from parental HCC827 and PC‐9 cells. HCC827‐OR cell‐derived exosomes induced EMT changes and resistance to osimertinib in HCC827 cells. Subsequently, the induction of miR‐210‐3p directly promoted the EMT phenomenon and resistance to osimertinib in HCC827 cells.ConclusionsExosomal miR‐210‐3p may play a crucial role in resistance to osimertinib in the tumor microenvironment of EGFR‐mutant NSCLC.

Published: May 2021

AbstractA 54‐year‐old male smoker presented with hemoptysis. Advanced lung adenocarcinoma, cT1cN3M1b, stage IVB, was diagnosed. Enlargement of multiple intraperitoneal and inguinal lymph nodes and peripheral atypical lymphocytosis appeared after 33 cycles of second‐line treatment with nivolumab, and a specimen obtained by left inguinal lymph node biopsy showed peripheral T cell lymphoma (PTCL), not otherwise specified. Lymphoma cells expressed CD3+, CD8+, and CD56+, but not CD4+ or PD‐1. Despite systemic chemotherapy with cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone, the patient died of PTCL 864 days after the initial visit. The possible relationship between treatment with immune checkpoint inhibitors (ICIs) and PTCL development is discussed here.
Linking fire behaviour and its ecological effects to plant traits, using FRaME in R
Authors: Zylstra Philip 
Published: May 2021

Abstract

Floral fire ecology incorporates a feedback loop in which plants influence fire behaviour and fire behaviour influences the flora. Recent advances in fire behaviour modelling have quantified many plant‐based drivers of fire behaviour, but the consequent ecological effects of this have not yet been adequately modelled mechanistically.

Here, I introduce the Fire Research and Modelling Environment (FRaME) as the open‐source R package frame on GitHub. FRaME calculates the influence of plants on fire behaviour using a biophysical, mechanistic model of fire behaviour, building this into complex simulations. From these, it models heat transfer from flames into surrounding surfaces, calculating its ecological effects on plants and soils. I demonstrate the application of the central analysis functions using a detailed case study, in which I validate predictions of fire behaviour and ecological effects, and derive quantitative measures for the efficacy of different management treatments to mitigate fire risk to a vulnerable ecosystem.

FRaME modelling predicted ecological effects such as the breaking of seed dormancy, scorch and the girdling of different tree strata, consistent with observed effects and providing insights into treatment efficacy that were not captured by existing assumptions. FRaME analyses were able to identify treatments that both increased the likelihood of success in containing fires and minimised fire impacts on a fire‐sensitive ecosystem.

FRaME provides a platform to examine the full role of fire in an ecosystem, from the ways that biota drive flammability to the influence of that flammability on the ecosystem. By mechanistically incorporating the effect of biophysical drivers throughout this feedback, FRaME can provide novel insights and solutions for complex problems, quantify risk and guide effective mitigation measures. The model is extensible, providing a conceptual framework into which emerging work on flammability and fire effects can be incorporated.
Prohibitin depletion extends lifespan of a TORC2/SGK‐1 mutant through autophagy and the mitochondrial UPR

Published: May 2021

AbstractMitochondrial prohibitins (PHB) are highly conserved proteins with a peculiar effect on lifespan. While PHB depletion shortens lifespan of wild‐type animals, it enhances longevity of a plethora of metabolically compromised mutants, including target of rapamycin complex 2 (TORC2) mutants sgk‐1 and rict‐1. Here, we show that sgk‐1 mutants have impaired mitochondrial homeostasis, lipogenesis and yolk formation, plausibly due to alterations in membrane lipid and sterol homeostasis. Remarkably, all these features are suppressed by PHB depletion. Our analysis shows the requirement of SRBP1/SBP‐1 for the lifespan extension of sgk‐1 mutants and the further extension conferred by PHB depletion. Moreover, although the mitochondrial unfolded protein response (UPRmt) and autophagy are induced in sgk‐1 mutants and upon PHB depletion, they are dispensable for lifespan. However, the enhanced longevity caused by PHB depletion in sgk‐1 mutants requires both, the UPRmt and autophagy, but not mitophagy. We hypothesize that UPRmt induction upon PHB depletion extends lifespan of sgk‐1 mutants through autophagy and probably modulation of lipid metabolism.

AbstractThis systematic review assessed the influence of conventional final irrigation with chelating solutions (CS) on tubular dentin sealer penetration (TDSP). The literature search was conducted in eight electronic databases using MeSH, DeCS, EMTREE and free terms. The study protocol followed the PRISMA guidelines and was registered on the PROSPERO database (CRD42020203080). Twelve studies were included, and a qualitative synthesis and network meta‐analysis of the data were performed. The risk of bias of the studies was assessed using an adaptation of the JBI Critical Appraisal tool. QMix was the solution with the highest probability of having the highest percentage of TDSP in the apical (34.1%), middle (86.5%) and coronal (97.7%) thirds. Eleven studies presented a moderate risk of bias, whereas one study presented a high risk of bias. In conclusion, CS improves sealer penetration into the dentinal tubules with QMix demonstrating superior results.

AbstractPurposeTo determine the risk of patients with an early diagnosis of heritable retinoblastoma being diagnosed with TRb (or pineoblastoma) asynchronously in a later stage and its effect on screening.MethodsWe updated the search (PubMed and Embase) for published literature as performed by our research group in 2014 and 2019. Trilateral retinoblastoma (TRb) patients were eligible for inclusion if identifiable as unique and the age at which TRb was diagnosed was available. The search yielded 97 new studies. Three new studies and eight new patients were included. Combined with 189 patients from the previous meta‐analysis, the database included 197 patients. The main outcome was the percentage of asynchronous TRb in patients diagnosed before and after preset age thresholds of 6 and 12 months of age at retinoblastoma diagnosis.ResultsSeventy‐nine per cent of patients with pineoblastoma are diagnosed with retinoblastoma before the age of 12 months. However, baseline MRI screening at time of retinoblastoma diagnosis fails to detect the later diagnosed pineal TRb in 89% of patients. We modelled that an additional MRI performed at the age of 29 months picks up 53% of pineoblastomas in an asymptomatic phase. The detection rate increased to 72%, 87% and 92%, respectively, with 2, 3 and 4 additional MRIs.ConclusionsAn MRI of the brain in heritable retinoblastoma before the age of 12 months misses most pineoblastomas, while retinoblastomas are diagnosed most often before the age of 12 months. Optimally timed additional MRI scans of the brain can increase the asymptomatic detection rate of pineoblastoma.
