High affinity of Skp to OmpC revealed by single-molecule detection
Authors: Pan Sichen , Yang Chen , Zhao Xin Sheng 
Published: April 2020

AbstractOuter membrane proteins (OMPs) are essential to Gram-negative bacteria, and they need molecular chaperones to prevent from aggregation in periplasm during the OMPs biogenesis. Seventeen kilodalton protein (Skp) is the major protein for this purpose. Here we used singlemolecule detection (SMD) to study the stoichiometry modulation of Skp in binding with outer membrane protein C (OmpC) fromEscherichia coli. To accomplish our task, we developed the tool of portion selectively chosen fluorescence correlation spectroscopy (pscFCS). We found that Skp binds OmpC with high affinity. The half concentration for Skp to form homotrimer Skp3(C1/2) was measured to be 250 nM. Under the Skp concentrations far belowC1/2OmpC can recruit Skp monomers to form OmpC·Skp3. The affinity of the process is in picomolar range, indicating that the trimerization of Skp in OmpC·Skp3complex is induced by OmpC-Skp interaction even though free Skp3is rarely present. In the concentration range that Skp3is the predominant form, OmpC may directly interact with Skp3. Under micro-molar concentrations of Skp, the formation of OmpC·(Skp3)2was observed. Our results suggest that the fine-tuned modulation of Skp composition stoichiometry plays an important role in the safe-guarding and quality control mechanism of OMPs in the periplasm.

Sectoral carbon linkages of Indian economy based on hypothetical extraction model
Authors: Sajid Muhammad Jawad , Cao Qingren , Cao Ming , Li Shuang 
Published: April 2020

PurposePresentation of the different industrial carbon linkages of India. The purpose of this paper is to understand the direct and indirect impact of these industrial linkages.Design/methodology/approachThis study uses a hypothetical extraction method with its various extensions. Under this method, different carbon linkages of a block are removed from the economy, and the effects of carbon linkages are determined by the difference between the original and the post-removal values. Energy and non-energy carbon linkages are also estimated.Findings“Electricity, gas and water supply (EGW)” at 655.61 Mt and 648.74 Mt had the highest total and forward linkages. “manufacturing and recycling” at 231.48 Mt had the highest backward linkage. High carbon-intensive blocks of “EGW” plus “mining and quarrying” were net emitters, while others were net absorbers. “Fuel and chemicals” at 0.08 Mt had almost neutral status. Hard coal was the main source of direct and indirect emissions.Practical implicationsNet emitting and key net forward blocks should reduce direct emission intensities. India should use its huge geographical potential for industrial accessibility to cheaper alternative energy. This alongside with technology/process improvements catalyzed by policy tools can help in mitigation efforts. Next, key net-backward blocks such as construction through intermediate purchases significantly stimulate emissions from other blocks. Tailored mitigation policies are needed in this regard.Originality/valueBy developing an understanding of India’s industrial carbon links, this study can guide policymakers. In addition, the paper lays out the framework for estimating energy and non-energy-based industrial carbon links.
Servant leadership and organizational citizenship behavior
Authors: Elche Dioni , Ruiz-Palomino Pablo , Linuesa-Langreo Jorge 
Published: April 2020

Purpose
This paper aims to process underlying the relationship between supervisor servant leadership and employee organizational citizenship behavior (OCB) in hotels. Specifically, it analyzes the mediating role of empathy – individual level – and service climate – group level – in the relationship between supervisor servant leadership and employee OCB.

Design/methodology/approach
The empirical analysis uses original data on hotels located in historic cities in Spain. A survey provided a sample of 343 work-group-level (supervisors) and 835 individual-level (employee) from a sample of 171 hotels.

Findings
The most interesting finding is the indirect effect of supervisor servant leadership on employee OCB through the mediating role of both employee empathy – individual level – and group service climate – group level.

Practical implications
The findings suggest that hotel supervisors should adopt servant leadership to enhance OCB in their workgroups. This paper also provides insights into other ways to increase employee OCB, namely, through human resources initiatives that enhance employee empathy and shape a service climate within groups.

Originality/value
This paper is one of the few that analyzes the relationships between supervisor servant leadership, employee empathy, group service climate and employee OCB in a unifying cross-level model. It is also the first to analyze employee empathy as a positive outcome of supervisor servant leadership, as well as a mechanism to explain the relationship between servant leadership and employee OCB. Finally, it is one of the few studies that analyzes all these relationships in conjunction within the hospitality industry.
Measuring the impact of lean practices on manufacturing performance – case study from the process industry
Authors: Kovács Tibor , Kő Andrea , Demeter Krisztina 
Published: April 2020

Purpose
This study aims to investigate how measuring the lean practices–performance relationship could add value to businesses.

Design/methodology/approach
Case-study methodology was used for the quantitative analysis of self-assessed lean capability scores and key manufacturing performance indicators from a global consumer goods company. Up to 80 sites over 3 years were analysed. Partial least squares structural equation modelling (PLS-SEM) is used to analyse the lean implementation–performance relationship.

Findings
Results show that different performance areas may be affected differently and suggest that the measured relationship may depend on the reliability of the self-assessment.

Research limitations/implications
The research is based on the manufacturing sites of a single company, implementing the same lean methodology, producing similar products and using similar process technologies. This helps to control confounding variables but may limit the generalisability of the findings.

Practical implications
Practitioners can use the measurement method to improve lean-based performance-improvement projects. The study suggests that the PLS-SEM technique could improve the calibration of lean-practice self-assessment and could identify further areas for improvement.

Originality/value
Very few papers developed measurement methods for the effectiveness of lean-practice implementation using objective manufacturing performance data within a single multinational company.
The impact of monetary systems on income inequity and wealth distribution
Authors: Othman Anwar Hasan Abdullah , Musa Alhabshi Syed , Kassim Salina , Abdullah Adam , Haron Razali 
Published: April 2020

PurposeThis study uses the autoregressive distributed lag model (ARDL) econometric approach to investigate empirically the effects of cryptocurrencies, the gold standard and traditional fiat money on global income inequality measured based on the Gini coefficient, and various ratios of income inequality distribution such as top 1 per cent, top 10 per cent, top 40 per cent and top 50 per cent.Design/methodology/approachThe study uses the ARDL econometric approach.FindingsThe findings indicated that cryptocurrency and gold standard monetary systems contributed significantly to reducing global inequality of income and wealth distribution. Conversely, the traditional fiat money system contributes positively to global income and wealth inequality while also contributing significantly to their fluctuation.Practical implicationsThis suggests that the fiat monetary system results in the coercive redistribution of income and wealth if governments pursue a social welfare policy. They must resolve this conflict between the current fiat monetary system and social policy by opting for an alternative monetary system such as cryptocurrency or gold standard. These alternative monetary systems offer the promise of resolving the income and wealth inequality associated with the traditional monetary system which are accompanied with the channels of inflation, lack of financial inclusion and debt creation, and to offer a more sustainable financial system.Originality/valueThe study recommends that monetary policy must be revisited to account for its direct effect on income and wealth redistribution to achieve social welfare goals.
Knowledge sharing in social networks: considering the role of political skill and trust
Authors: Seitz Stephanie R. , Misra Kaumudi 
Published: April 2020

PurposeThe purpose of this paper is to bring a more individual focus to social networks in theorizing the social process of knowledge sharing.Design/methodology/approachThe theoretical model proposes that political skill will shape an individual's social network. Further, political skill within a network will influence the degree of complex knowledge sharing, which likely happens through the mechanism of affective- and cognitive-based trust.FindingsTheoretical implications and future research directions are discussed.Originality/valueKnowledge sharing is an inherently social process and as such occurs within the context of social networks in an organization. However, research to date has not fully explored the details of how and why complex knowledge sharing happens within a social network. Generally, theory on social networks has focused on structural qualities of a network, rather than the individual characteristics of the members of that network. This paper brings a more individual focus to social networks in theorizing the social process of knowledge sharing.
Authentic leadership and citizenship behavior
Authors: Kyei-Poku Ivy , Yang Ying (Jason) 
Published: April 2020

PurposeThe purpose of this study is to assess the pathway through which authentic leadership influences organizational citizenship behavior (OCB). The authors examine how the perception of overall fairness and a sense of belongingness mediate the relationship between authentic leadership and OCB.Design/methodology/approachThe authors distributed survey questionnaires to full-time employees working for an insurance company. Data were collected in two phases. To test the hypotheses, the authors conducted hierarchical multiple regression analysis using the PROCESS macro by Hayes (2012).FindingsPROCESS analysis reveals that overall fairness mediates the relationship between authentic leadership and subordinates' sense of belongingness, which is then positively related to OCB. Taken together, these findings are largely in line with the authors’ theoretical model.Originality/valueEmpirical research has yet to explore how authentic leaders create the perception of fairness, which influences subordinates' OCB. Thus, this study extends the authors’ knowledge on the extant literature of organizational behavior by integrating two important domains—authentic leadership and organizational fairness—to propose that authentic leadership is a fair leadership that aids in promoting OCB. Also, studies on authentic leadership processes have examined basic models and neglected the possibility of sequential mediation. To better understand the complex relationship of authentic leadership and OCB, the authors examine overall fairness and belongingness as sequential mediators.
Influence of empowerment, psychological contract and employee engagement on voluntary turnover intentions
Authors: S Sandhya , M M Sulphey 
Published: April 2020

PurposeThe purpose of the study is to explore the influence of psychological empowerment, psychological contract and employee engagement on voluntary turnover intentions of employees in theinformation technology (IT) industry.Design/methodology/approachThe study used a cross-sectional, quantitative research design. The analysis for the study is based on a sample of 392 Indian IT professionals. Partial least square–structural equation modelling (PLS-SEM) was used to analyse the data.FindingsThis study has identified a significant relationship between turnover intentions, employee engagement, psychological contract and psychological empowerment. The findings of the study are that there exists significant positive influence of psychological contract and psychological empowerment on employee engagement. Employee engagement, in turn, has the capability to influence intention to leave the organization.Originality/valueThere is heightened awareness among industry leaders about the need to retain top performers. However, organizations are found to repeatedly fail in this regard. The study has succeeded in empirically establishing the complex relationship between empowerment, psychological contract, employee engagement and turnover intentions. The findings of the study are significant and have practical implications. It can be put to use by progressive managements in devising strategies to reduce turnover intentions.
The performance of Generation II journal gas foil bearing with misalignment
Authors: Li Hao , Geng Peng Hai , Lin Hao 
Published: April 2020

Purpose
The normal operation of a rotor system is generally vulnerable to misalignment between gas foil bearing (GFB) and rotor. However, most theoretical and experimental researches about the characteristics of GFBs have ignored this phenomenon. Therefore, the main purpose of this paper is to evaluate the static and dynamic performance of GFBs considering misalignment.

Design/methodology/approach
The shaft is allowed to misalign in two directions. Then the variations of bearing load, friction force, restoring moment, stiffness and damping coefficients are thoroughly explored. The hydrodynamic pressure on the gas film is modeled with compressible Reynolds equation, and the deformation of the flexible bearing is calculated with finite element method. Small perturbation method is used to obtain the displacement and moment dynamic coefficients.

Findings
The film thickness and pressure distribution distort when misalignments appear. The inclination of GFBs can enhance the restoring moment to withstand the imposed misalignment. Furthermore, the simulation phenomenon demonstrates the misalignment around load direction should be avoided as much as possible, while a small value misalignment around another direction is allowed.

Originality/value
The value of this paper is the exploration of the influence of misalignments on the static and dynamic performance of the Generation II journal GFB.

Preparation of self-lubricating coating by mechanical milling
Authors: Yan Chengqi , Karthik Namachivayam , Kang Yonghai , Xiong Dangsheng 
Published: April 2020

Purpose
This paper aims to fabricate nickel-aluminum (Ni-Al)-based self-lubricating composite coating on aluminum (Al) alloy by mechanical milling (MM).

Design/methodology/approach
A new carrier transport (CT) way was designed to solve the slippage fracture of the coating due to silver (Ag) accumulation (Ag powders were cold welded with nickel [Ni] powders by MM in advance to avoid accumulation, then Al powder and samples were added to fabricate the coating).

Findings
Microstructure analysis reveals that the solid lubricant Ag exists as particles in the composite coating via CT technique, which is different from the typical morphology (strip-type) of Ag tailored by normal methods. The unique granular form of Ag can effectively avoid the gliding fracture of the coating, thus forming an efficacious lubrication film on the worn surface, which is responsible for the excellent tribological properties of the coating.

Practical implications
Most of the papers reported that coatings synthesized by MM mainly concentrated on hard coatings, but the fabrication of self-lubricating coatings have not yet reported.

Originality/value
The uniform dispersion of solid lubricant Ag can effectively solves a fatal problem that the fracture failure of coating triggered by the Ag accumulation. This experiment provides a novel method for preparation of self-lubricating coating by MM.

Cultures and entrepreneurial competencies; ethnic propensities and performance in Malaysia
Authors: Tehseen Shehnaz , Anderson Alistair R. 
Published: April 2020

Purpose
The purpose of this study is to examine the extent and types of entrepreneurial competences among culturally different ethnic groups in Malaysia. Malaysia offers us a similar environment and ecosystem to make comparisons within a single context.

Design/methodology/approach
This paper surveyed 600 respondents – 200 Malaysian Chinese, 200 Malaysian Indians and 200 Malays – and collected data about the types of competencies and about self-reported growth as firm performance. The study used PLS-SEM for inferential testing and PLS-MGA to conduct multigroup analysis among the three ethnic groups and found considerable and interesting differences.

Findings
The results of the nuanced, fine-grained findings showed a distinctive distribution of competencies. This study investigates the analysis further to argue that there is an ethnic disposition to favour and value different competencies. Broadly, Malaysian Chinese have a commercial outlook which contrasts with the Malaysian emphasis on social values such as family. Malaysian Indians’ competencies are similar to Malaysian Chinese’s, but with more social value emphasised. This distribution impacts on firm performance with Malaysian Chinese firms faring economically better. However, this economic measure takes no account of social measures which may be an important determinant and motivation for some ethnic groups.

Research limitations/implications
Theoretically, it becomes evident that one size does not fit all. In practice, different competencies are prioritised. Hence competencies appear to be culturally shaped. Culture influences what might be seen as very practical dimensions of entrepreneuring. From a practical perspective, those encouraging entrepreneurship should take such differences into account.

Originality/value
The study is original in comparing cultural effects on competencies and performance.
Quality antecedents and performance outcome of cloud-based hospital information system continuance intention
Authors: Cheng Yung-Ming 
Published: April 2020

PurposeThis study's purpose is to propose an integrated model based on expectation-confirmation model (ECM), task-technology fit (TTF) model, and updated DeLone and McLean information system (IS) success model to examine whether quality factors and TTF as antecedents to physician beliefs can affect physicians' continuance intention of the cloud-based hospital information system (HIS) and performance impact.Design/methodology/approachSample data for this study were collected from physicians at five hospitals in Taiwan. A total of 500 questionnaires were distributed, and 305 (61.0 percent) usable questionnaires were analyzed using structural equation modeling in this study.FindingsThis study verified that physicians' perceived information quality, system quality, general technical support service quality, and cloud storage service quality all positively caused their PU, confirmation, and perceived TTF in the cloud-based HIS, which together explained their satisfaction with the system, and subsequently led to their continuance intention of the system and performance impact.Originality/valueFirst, IS-related and cloud-related quality factors are simultaneously taken into consideration within this study's research model, and empirical results reveal deep insights into quality evaluation in the field of physicians' cloud-based HIS continuance intention. Next, this study contributes to an understanding of TTF in explaining physicians' cloud-based HIS continuance intention that is difficult to explain with only their utilitarian perception of the system, and places emphasis upon physicians' perception of performance impact greatly driven by their perceived TTF and continuance intention of the system, thus the results can shed light on antecedents and outcome of physicians' cloud-based HIS continuance intention.
Bank efficiency in Bangladesh revisited: a slack-based network DEA approach
Authors: Azad Md. Abul Kalam , Wanke Peter , Raihan Mohammad Zahir , Anwar S.M. Rakibul , Mustafa Riduanul 
Published: April 2020

PurposeData envelopment analysis (DEA) calculates the efficiency of a business unit if all the inputs are creating outputs within a “black box.” Under traditional DEA, the detailed process of that business unit is ignored. However, a network DEA can explain the black box structure and provide efficiency results for sub-sections within any business process. This study aims to propose a network DEA model that explains a bank's total operation.Design/methodology/approachEarlier studies have focused only on bank efficiency ignoring this breakdown. This study departs from them by using a slack-based two-stage network DEA under a novel banking business perspective.FindingsThe results reveal that network DEA provides better benchmarking insights than the traditional DEA. As such, better benchmarking can guide both the banking industry managers and policy makers in Bangladesh.Originality/valueThe major contribution of this study includes dividing a bank's total operation efficiency into two sub-operations: “core operations – collecting deposits and giving loans” and “additional operations – fees, commissions and other services.”
