Ethics beyond leadership: can ethics survive bad leadership?
Authors: Roque Ana , Moreira José Manuel , Dias Figueiredo José , Albuquerque Rosana , Gonçalves Helena 
Published: July 2020

PurposeThe purpose of this paper is to contribute to the relaxion on what can be done to develop ethical cultures that may be less permeable and more resilient to changes in leadership from an ethical point of view. The influence of leaders on organisational ethics is recognised, and there are even those who consider that it is not possible to maintain an ethical culture when leaders are not engaged. But, if this theory is true, all business ethics programmes that can be created, and the cultures that can gradually be developed in organisations, will always have their existence and robustness suspended at each leadership change. How to maintain an ethical culture beyond leadership?Design/methodology/approachAs a strategy, we used the case study with a narrative methodology, in which a chief executive officer (CEO) and a chief compliance officer (CCO) narrate in the first person a case of perceived collapse of the ethical culture of a multinational company.FindingsThe findings point to the difficulty in maintaining ethical leadership. Key aspects to protect an organization from leadership changes are as follows: the management of the succession process, the quality of the training on ethics and the mechanisms developed by the organization to foment speak up and take notice of the situations. Moral blindness and the banality of evil that also can be observed in organizations appear as facilitating elements for collapse.Originality/valueEthical leadership is generally presented as a necessary condition for an ethical culture. However, leaders often have unethical or ethically neutral leadership. This case helps to understand the difficulties experienced by leaders in adopting ethical leadership and proposes a set of instruments and procedures that, when included in an ethical programme, can protect the company's ethical culture against unethical leaders. Some characteristics of our case study make it particularly relevant: action occurs in a multinational, a context where, by size and complexity, achieving uniformity in culture becomes particularly relevant, and actions happen in the context of a CEO succession process, something that may occur in any company and which is often a trigger for ethical misconducts. Additionally, our case is narrated by a CEO and a CCO, which makes it rare, as it is especially difficult to have access to these executives.

Authors: Woods Stephen A. , Diprose Nick , Murphy-Diprose Mary , Thomas Geoff 
Published: July 2020

PurposeThis paper reviews literature on interim leadership and management through the lens of effective interim performance. The purpose of this review is to advance understanding of interim assignment performance and the antecedent individual psychological characteristics of effective interim leaders and managers, to improve the practice of managing interim leaders from a human resources (HR) perspective.Design/methodology/approachThe paper reports a targeted review of the literature on interim leadership and management.FindingsThe main proposition from this review is that the influence of individual factors on interim performance operates within the stages and contexts of assignments. Accordingly, the authors propose a framework of the demands on interim assignments (the interim assignment cycle), comprising stages of preparation, entry, delivery and exit. The paper subsequently reviews evidence of the potential individual characteristics (focussing on individual differences in personality, leadership approach, motivation and competencies) of effective preparation and entry to an assignment, actions and performance during an assignment and exit/disengagement.Practical implicationsThe findings of the review have implications for the selection and placement of interims into organizations and their management once appointed.Originality/valueThe main original contribution of the paper is to provide a framework around which interim assignments can be modelled and better understood. The paper discusses implications for future research, theory and human resource management practice and calls for a renewed research effort in this critical area of management and leadership.
Remarkable lives: Rob Wright in conversation with Jerome Carson
Authors: Carson Jerome , Wright Robert 
Published: July 2020

Purpose
The purpose of this paper is to provide a profile of Rob Wright.

Design/methodology/approach
Using a case study approach, Rob gives a short account of his background and is then interviewed by Jerome.

Findings
Rob’s is an amazing account of surviving a harrowing upbringing, which fortunately few of us reading this piece will have had to endure.

Research limitations/implications
Rob’s story perfectly illustrates why first-person accounts are so powerful. It is hard to imagine a statistical paper having the same impact as this description of one person’s lived experience.

Practical implications
Suicide is the greatest danger for anyone with a long-term mental health problem. Rob has faced this decision many times and has courageously battled on.

Social implications
Rachel’s simple, yet profound mantra, of “someone to love, something to do, somewhere to live,” is vital for all of our well-being. As Rob also points out, you still need money to put into the electric meter!

Originality/value
Some people have tough upbringings and some have cruel upbringings. Rob had both. His survival is a testament to the uncrushable nature of the human spirit.
Assessment of antioxidant activity, minerals and chemical constituents of edible mahua (Madhuca longifolia) flower and fruit of using principal component analysis
Authors: Singh Vinti , Singh Jyotsana , Kushwaha Radha , Singh Monika , Kumar Sandeep , Rai Awadhesh Kumar 
Published: July 2020

Purpose
Flowers and fruits of Madhuca longifolia (Koenig) (mahua) tree are edible and used as traditional Indian medicines. The physicochemical properties of different parts of mahua are investigated. This study aims to estimate the different mineral contents, polyphenols compounds and antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl inhibition, reducing power, free radical scavenging activity using 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) and ferric reducing antioxidant power assays of mahua flower, ripe and unripe fruit.

Design/methodology/approach
Flavonoids were identified and quantified in yellow flowers and fruits of M. longifolia tree by high-performance liquid chromatography with diode array detector. Low molecular weight carbohydrates were determined by the ICBio scan, a specific method for determining of carbohydrates. Mineral content is determined by laser-induced breakdown spectroscopy (LIBS) and atomic absorption spectroscopy. Physicochemical, nutritional and mineral properties of mahua flower, ripe and unripe fruit were investigated by the statistical approach of principal component analysis (PCA).

Findings
Ascorbic acid, gallic acid (GA), quercetin and myrcetin were the phenolic compounds identified and quantified in mahua flower and fruit extracts. Sugar profiling of mahua flowers and fruits confirmed the presence of inositol, sorbitol, mannitol, dextrose, fructose, sucrose, raffinose and maltose. The mineral content of Na, K, Mg and Ca was present in quite a good amount in all samples. Total phenolic content (TPC) was significantly high in mahua flower (25.3 ± 1.0 mg GA equivalent/g FW) followed by mahua unripe (15.8 ± 1.0 mg GA equivalent/g FW) and ripe fruit (14.3 ± 1.0 mg GA equivalent/g FW) at p = 5%. In contrast, total flavonoid contents (TFCs) were highest in ripe fruit, then mahua flower and unripe fruit. Positive correlations were predicted by PCA for mahua flower with TPC, antioxidant activity assays and minerals except for Na; ripe fruit with TFC and Na; and unripe fruit with maltose and sorbitol.

Originality/value
This study demonstrates the application of LIBS for the determination of elements present in the mahua flowers and fruits and reveals that mahua can be a good source of nutrients. Sugar profiling of mahua flower showed that it is a rich source of reducing and non-reducing sugar, proving that mahua flower juice can be used as a natural sweetener in the development of different food products, namely, biscuits, cookies, cake, jam, jelly, juice and squash.

Authors: Kim Dong Sung (Danny) , Suriboot Jakkrit , Shih Chin-Cheng , Cwiklik Austin , Grunlan Melissa A. , Tai Bruce L. 
Published: July 2020

Purpose
This paper aims to investigate the printability of photocurable PDMS with digital light processing (DLP) in terms of dimensional accuracy, mechanical properties, isotropy and postcure shrinkage.

Design/methodology/approach
The photocurable PDMS was made from methacrylated PDMS-macromer and 2,4,6-Trimethylbenzoyldi-Phenylphosphinate (TPO-L) photoinitiator. The PDMS was printed using different orientations, sizes and post-exposure conditions and then evaluated by tensile test and microscope to determine the printability.

Findings
Printed parts show good accuracy and low shrinkage, but high directionality in modulus, ductility and strength. The dimensional error is less than 2% and the shrinkage rates are less than 0.52%. In contrast, the modulus varies between 0.87 and 0.96 MPa depending on print orientation, elongation varies from 34.7% to 66.4% and strength varies from 0.23 to 0.49 MPa.

Originality/value
This study quantitatively characterizes the printability of photo curable PDMS with DLP, which has not been reported elsewhere. This paper also discusses the challenges of PDMS printing for future advancement.
The nexus of economic growth, priority sector lending and non-performing assets: case of Indian banking sector
Authors: Gaur Dolly , Mohapatra Dipti Ranjan 
Published: July 2020

PurposeIn recent years, the Indian banking sector is facing a major cause of concern in the form of Nonperforming Assets (NPA), and the priority sector lending (PSL) is generally recognized as the major factor contributing to it. Thus, the present study has been carried out with the objective of examining the relationship between priority sector lending and GDP growth. Thereafter, the role of PSL and certain other bank-specific, industry-specific and macroeconomic variables in determining NPA has been studied.Design/methodology/approachTaking a sample of 45 scheduled commercial banks, the study has been carried out for 14 years (2004–2018). Granger causality between PSL and GDP has been examined by applying the Dumitrescu-Hurlin test. For the purpose of investigating the impact of PSL and other determinants on NPA, both static and dynamic panel regression have been performed. Under the dynamic panel, system generalized methods of moments (S-GMM) approach has been followed.FindingsThe findings show that there exists a positive correlation and bidirectional causal relationship between PSL and GDP, which implies that PSL brings additional growth for the whole economy. In addition to it, PSL is found to be insignificant for the NPA ratio, and thus, it can be inferred that credit extended to government-specified sectors does not bring any major increase in the bad loan portfolio of banks.Practical implicationsThe policymakers and bank management can take a cue from the findings of this study to decrease the exposure to loan nonrepayment issue. The priority sectors are in need of formal credit for their growth, and since the rising population of the country can find employment in these sectors, banks should meet their credit needs while securing their position with regard to the NPA problem.Originality/valueThe issue of NPA determinants, and in particular, the contribution of priority sector lending in it has not been much explored for Indian banking sector. Also, the present study adds to the literature by using the causality approach for examining the importance of directed credit schemes for economic growth.

Published: July 2020

PurposeThis paper empirically provides information on community-driven infrastructure provision through the collective efforts of community-based organizations (CBOs). It offers an insight into emerging events on community-based infrastructure procurement, scholarship and, creating gaps for new frontiers of knowledge on community development research agenda in the emerging economies.Design/methodology/approachIt is drawn upon community-based associations, herein referred to as landlords-landladies community association (LLCAs) – representatives of households in the communities. After interviewing the key members of the groups, we administered copies of the semi-structured questionnaire randomly on the enumerated regular members of sampled seventeen LLCAs. Data were analyzed using descriptive and inferential statistics.FindingsPlanning for a sustainable community, protection and security necessity and Government inadequate attention on emerging communities over the years are the main reasons for the joint decision. Electrification, drainage and road top the lists of the projects executed. Major challenges included diversity and inclusiveness. Development projects' design, execution and commission contribute to performance. Also, LLCAs' clarity of duties and purposes and tenure/duration of officials contribute to the overall membership satisfaction on governance structure and leadership.Research limitations/implicationsIt is limited to the specific reasons for collective efforts, challenges of the participatory movement, membership satisfaction on governance and infrastructure recently procured in the communities. Frontier of studies should be extended to enabling factors.Practical implicationsFindings from this study indicate that community-driven governance with the support of the government enhances community-based infrastructure.Social implicationsPotential values of collective action embellished in the concepts of a social movement, active engagement, communalism, grassroots efforts, social cohesion and planning in bringing peoples of diversities together for common goals with less rigorous formalization.Originality/valueThe novelty of the research is the exposition on the evidence-based innovative concept of integrating the social practice of participatory design, representing a bottom-up model into infrastructure procurement in community settings.
Strategic sustainable purchasing, environmental collaboration, and organizational sustainability performance: the moderating role of supply base size
Authors: Arora Amit , Arora Anshu Saxena , Sivakumar K. , Burke Gerard 
Published: July 2020

Purpose
This paper aims to examines the moderating effect of small vs large supply base size on the relationship between strategic sustainable purchasing (SSP) and organizational sustainability performance (OSP). SSP is conceptualized as a dynamic capability consisting of strategic purchasing and environmental purchasing. Environmental collaboration is conceptualized as a mediator between SSP and OSP. Extant research has not examined the effect of the size of the supply base on the relationship between SSP and OSP.

Design/methodology/approach
The hypothesized relationships are tested using a two-step multi-group analysis in partial least squares-structural equation modeling (PLS-SEM).

Findings
A small supply base size positively moderates the relationship between SSP and environmental collaboration, thus achieving OSP. In contrast, when the supply base is large, strategic purchasing is positively associated with environmental collaboration, while environmental purchasing is negatively related to environmental collaboration. A large supply base has a positive relationship to environmental collaboration and economic sustainability, while the relationship between environmental collaboration and environmental and social performance is not significant.

Practical implications
This research argues that despite the nuances in the moderating effects of small versus large supply base size, managers need to invest in both dynamic and relational capabilities to achieve organizational sustainability.

Originality/value
Scant research is available in supply chain management research that has examined the important effect of the supply base size on the relationship between SSP and OSP. This research aims to fill this gap. The study helps practitioners understand the effects of supply base sizes for their organizations, increase interrelationships among suppliers, reduce the level of differentiation among them, and, thereby, reduce costs and increase revenues.
Asymmetric Cost Behavior and Dividend Policy
Authors: HE JIE , TIAN XUAN , YANG HUAN , ZUO LUO 
Published: July 2020

ABSTRACTCosts are sticky on average, that is, they fall less for sales decreases than they rise for equivalent sales increases. We examine the effect of this asymmetric cost behavior on a firm's dividend policy. Given investors’ aversion to dividend cuts, we predict that firms with higher resource adjustment costs and stickier costs pay lower dividends than their peers because they are less able to sustain any higher level of dividend payouts in the future. We find evidence consistent with this prediction. Further, using a regression discontinuity design that exploits variation in labor adjustment costs generated by close‐call union elections, we provide evidence suggesting that the negative relation between cost stickiness and dividend payouts is driven by resource adjustment costs. Our paper sheds new light on the determinants of dividend policy and demonstrates the role of cost behavior in corporate decisions.

AbstractClimate change is generating range shifts in many organisms, notably along the elevational gradient in mountainous environments. However, moving up in elevation exposes organisms to lower oxygen availability, which may reduce the successful reproduction and development of oviparous organisms. To test this possibility in an upward‐colonizing species, we artificially incubated developing embryos of the viperine snake (Natrix maura) using a split‐clutch design, in conditions of extreme high elevation (hypoxia at 2877 m above sea level; 72% sea‐level equivalent O2availability) or low elevation (control group; i.e. normoxia at 436 m above sea level). Hatching success did not differ between the two treatments. Embryos developing at extreme high elevation had higher heart rates and hatched earlier, resulting in hatchlings that were smaller in body size and slower swimmers compared to their siblings incubated at lower elevation. Furthermore, post‐hatching reciprocal transplant of juveniles showed that snakes which developed at extreme high elevation, when transferred back to low elevation, did not recover full performance compared to their siblings from the low elevation incubation treatment. These results suggest that incubation at extreme high elevation, including the effects of hypoxia, will not prevent oviparous ectotherms from producing viable young, but may pose significant physiological challenges on developing offspringin ovo. These early‐life performance limitations imposed by extreme high elevation could have negative consequences on adult phenotypes, including on fitness‐related traits.
CEACAM6 promotes cisplatin resistance in lung adenocarcinoma and is regulated by microRNA‐146a and microRNA‐26a
Authors: Du He , Li Yang , Sun Rongrong , Yuan Yuan , Sun Sanyuan , Zhang Youwei 
Published: July 2020

BackgroundCarcinoembryonic antigen (CEA)‐related cell adhesion molecule 6 (CEACAM6) is a glycophosphoinositol‐anchored glycoprotein which mediates cell‐cell interactions. Here, we aimed to explore the specific functions and regulatory mechanisms of CEACAM6 on cisplatin (DDP) in lung adenocarcinoma (LUAD).MethodsRNA sequencing was performed in the DDP‐resistant A549/DDP cell line and parental A549 cell line; miRNA expression profiling of the two cell lines was analyzed using GEO data (GSE43249). Gain‐ and loss‐of‐function experiments were used to investigate the biological function of CEACAM6 in vitro. The expression status and prognostic value of CEACAM6 in LUAD were verified using The Cancer Genome Atlas (TCGA) database.ResultsCEACAM6 was first screened to be one of the most significantly upregulated genes in the DDP‐resistant A549/DDP cell line compared to the parental A549 cell line. Combined with computational prediction of candidate miRNAs that target CEACAM6, miR‐146a and miR‐26a were selected and verified by qPCR and luciferase reporter assay. The knockdown of CEACAM6 expression in A549/DDP cells inhibited cell proliferation, invasion and migration, decreased the IC50 values of DDP, and caused a significant downregulation of N‐cadherin, vimentin, Sox2, Oct4 and GTP‐RhoA and upregulation of E‐cadherin; while CEACAM6 overexpression in A549 cells resulted in the opposite effects. Of note, both miR‐146a and miR‐26a could counteract the biological effects of CEACAM6. Furthermore, CEACAM6 mRNA expression was significantly unregulated in DDP‐resistant LUAD tissues of TCGA database.ConclusionsCEACAM6 promotes DDP resistance in LUAD by affecting the epithelial‐mesenchymal transition (EMT) phenotype and stemness, which is post‐transcriptionally regulated by miR‐146a and miR‐26a.
Modal non‐linear regression in the presence of Laplace measurement error
Authors: Shi Jianhong , Zhang Jie , Wang Xiaorui , Song Weixing 
Published: July 2020

SummaryIn this paper, we propose a robust estimation procedure for a class of non‐linear regression models when the covariates are contaminated with Laplace measurement error, aiming at constructing an estimation procedure for the regression parameters which are less affected by the possible outliers, and heavy‐tailed underlying distribution, as well as reducing the bias introduced by the measurement error. Starting with the modal regression procedure developed for the measurement error‐free case, a non‐trivial modification is made so that the modified version can effectively correct the potential bias caused by measurement error. Large sample properties of the proposed estimate, such as the convergence rate and the asymptotic normality, are thoroughly investigated. A simulation study and real data application are conducted to illustrate the satisfying finite sample performance of the proposed estimation procedure.
