Performance investigation of doubly salient outer rotor switched reluctance motor using finite element analysis
Authors: Sivasamy Saravanan , Maria M. Marsaline Beno , Sundaramoorthy Prabhu 
Published: July 2021

Purpose
The automotive industry extensively uses switched reluctance motors (SRM) because of their excellent performance. The main purpose of this article is to investigate the design of a particular type of SRM called doubly salient outer rotor switched reluctance motor (DSORSRM) for electric vehicle application in this paper.

Design/methodology/approach
Different configurations of DSORSRM motor such as long flux path SRM, reduced flux path mutually coupled SRM and short flux path SRM (SF-SRM) are considered for investigation. The best configuration based on average torque is selected for further investigation by conducting an electromagnetic analysis. Also, in the proposed design, laminating material with low iron loss and superior performance characteristics is selected by doing electromagnetic analysis for SRM with M19, M660-50D, M-19 and M800-100A non-oriented laminating core material. Because vibrations are produced in DSORSRM devices as a result of changing induction, a mechanical analysis was performed to estimate the natural frequencies of vibration and the amplitudes that may lead to acoustic noises.

Findings
SF-SRM configuration with three-phase, 12/10, 250 W, 48 V, 1,000 rpm is selected with the impact in the elimination of flux reversals and also has various salient features such as singly excited, no rotor windings, no permanent magnet, pure in construction and high starting torque. Still, this SRM suffers from vibration owing to changing induction. In lamination material selection, M19 is chosen as optimized material to obtain vibration reduction. Vibration analysis was performed for the optimized 12/10 SF-SRM with M19 lamination material, and the corresponding modes for the machine to operate with reduced vibration are analyzed. The current and speed characteristics of the prototype model for the DSORSRM motor are obtained and validated with finite element analysis (FEA) results.

Originality/value
The performed FEA result shows that the proposed DSORSRM with short flux path configuration produces a high average torque of 1.915 N m. The M19 lamination material gives a minimum iron loss of 9.056 W. The modal frequencies are estimated and validated with numerical equations.

The GMRES solver for the interpolating meshless local Petrov–Galerkin method applied to heat conduction
Authors: Singh Abhishek Kumar , Singh Krishna Mohan 
Published: July 2021

PurposeThe work presents a novel implementation of the generalized minimum residual (GMRES) solver in conjunction with the interpolating meshless local Petrov–Galerkin (MLPG) method to solve steady-state heat conduction in 2-D as well as in 3-D domains.Design/methodology/approachThe restarted version of the GMRES solver (with and without preconditioner) is applied to solve an asymmetric system of equations, arising due to the interpolating MLPG formulation. Its performance is compared with the biconjugate gradient stabilized (BiCGSTAB) solver on the basis of computation time and convergence behaviour. Jacobi and successive over-relaxation (SOR) methods are used as the preconditioners in both the solvers.FindingsThe results show that the GMRES solver outperforms the BiCGSTAB solver in terms of smoothness of convergence behaviour, while performs slightly better than the BiCGSTAB method in terms of Central processing Unit (CPU) time.Originality/valueMLPG formulation leads to a non-symmetric system of algebraic equations. Iterative methods such as GMRES and BiCGSTAB methods are required for its solution for large-scale problems. This work presents the use of GMRES solver with the MLPG method for the very first time.

Authors: Ayoub Alaa Eldin Abdel Hamid , Almahamid Soud Mohammad , Al Salah Luma F. 
Published: July 2021

PurposeThe study aims to develop an innovative work behavior (IWB) scale for the faculty members and faculty leaders of universities in the Gulf Cooperation Council Countries (GCC). This research is intended for assessing the level of IWB in higher education and evaluating its psychometric properties.Design/methodology/approachThe study targets academic staff of universities in the GCC region, and out of 810 questionnaires that were distributed, only 773 valid responses were obtained of which 517 were responses from males and 256 from females whose ages range between 33 and 67 years.FindingsThe exploratory and confirmatory factor analyses were used and confirmed a five-factor structural model (opportunity exploration, idea generation, idea promotion, idea realization and idea sustainability), and the model has a satisfactory fit. The scale consists of 27 items with high Cronbach's alpha value of 0.87, demonstrating good internal consistency. Preliminary results suggest that the IWB scale has adequate convergent and divergent validity.Practical implicationsThe IWB scale can be a useful tool for evaluating and developing a high level of innovative work behavior that maintains university services' sustainability and increases industries' competitiveness.Originality/valueThis research provides insights into the importance of IWB in achieving tangible success to the educational institutions. It provides a new method to confront sudden and unexpected circumstance such as what has happened during COVID-19 pandemic.
Customer involvement, business capabilities and new product performance
Authors: Chen Yen-Chun , Arnold Todd , Tsai Hsien-Tung 
Published: July 2021

Purpose
This study aims to test the role of a firm’s marketing and technological capabilities in mediating the relationship between customer involvement in information provision (CIP) and customer involvement in coproduction (CIC) and new product performance, while also investigating the impact of the interactive effect of such capabilities. This investigation is at the firm rather than the project level.

Design/methodology/approach
A survey-based questionnaire was distributed to senior managers from 101 Taiwanese electronics firms. The research model and hypotheses were evaluated using partial least squares structural equation modeling in SmartPLS 3.

Findings
CIP and CIC improve new product performance indirectly through the development of marketing and technological capabilities. CIP has a stronger positive effect on marketing capabilities than CIC. In addition, the interactive effect of marketing and technological capabilities on new product performance is positive and significant.

Research limitations/implications
The data came from a single respondent in each firm, which may lead to common method bias. In addition, the data were cross-sectional in nature, having been collected at a single point in time. This limits the ability to draw causal inferences, as would be possible with longitudinal data. Finally, the data came from a single industry in only one country.

Practical implications
CIC is useful in terms of product idea generation and screening, as well as in helping to effectively learn and combine market knowledge from customers, whereas CIP takes on a more active role in strengthening marketing capabilities. Managers should understand these direct effects of CIP and CIC, as well as their indirect effects on new product performance.

Originality/value
Previous empirical research is largely limited to project-level implications such as innovativeness, advantages and the financial performance of a specific new product; a clear understanding of the strategic, firm-level implications of CIP and CIC in the context of new product development is lacking. The findings highlight the importance of treating CIP and CIC as continuous processes in a firm rather than viewing each in isolation to a specific project.

A novel buoyancy-modified subgrid-scale model for large-eddy simulation of turbulent convection
Authors: Yilmaz Ilyas 
Published: July 2021

Purpose
The purpose of this paper is to develop a subgrid-scale (SGS) model for large eddy simulation (LES) of buoyancy- and thermally driven transitional and turbulent flows and further examine its performance.

Design/methodology/approach
Favre-filtered, non-dimensional LES equations are solved using non-dissipative, fully implicit, kinetic energy conserving, finite-volume algorithm which uses an iterative predictor-corrector approach based on pressure correction. Also, to develop a new SGS model which accounts for buoyancy, turbulent generation term in SGS viscosity is properly modified and enhanced by buoyancy production.

Findings
The proposed model has been successfully applied to turbulent Rayleigh–Bénard convection. The results show that the model is able to reproduce the complex physics of turbulent thermal convection. In comparison with the original wall-adapting local eddy-viscosity (WALE) and buoyancy-modified (BM) Smagorinsky models, turbulent diagnostics predicted by the new model are in better agreement with direct numerical simulation.

Originality/value
A BM variant of the WALE SGS model is newly developed and analyzed.

The brand persona of a football manager – the case of Arsène Wenger
Authors: Berndt Adele 
Published: July 2021

PurposeSport is an important economic activity, and understanding the role of teams and managers is necessary, yet managers – specifically their brand personas – have been the subject of limited research. The purpose of this research is to explore the brand persona of a football manager, using Arsène Wenger as a case.Design/methodology/approachDue to the exploratory nature of the study, qualitative methods were used to explore the brand-building activity. Media reports and images that centred on Arsène Wenger's words covering a three-year period were analysed. In total, 1364 articles and 23 images were analysed in NVivo, using botha prioriand emergent codes.FindingsThe findings show the construction of the brand persona in three main dimensions pertinent to his role as a manager. The first is the performance in the managerial role in which Arsène Wenger is appointed, the second is associated with the person (including emotions and self-expression) and the third is the context (i.e. football) in which the manager operates.Research limitations/implicationsThe research focused on one manager while he was managing a premier league club and is limited to England.Practical implicationsWhile proposing a theoretical model, this study proposes football clubs understand a manager's persona in relation to the club's brand and the interactive effect. The support of the club on the persona is also indicated.Originality/valueFootball managers have received some research attention, but there has been no analysis of their brand personas. This study expands the understanding of the contribution of the manager to the club brand.

Authors: Li Jian , Gong Yanping , Xie Julan , Tan Yuxuan 
Published: July 2021

PurposeThe purpose of this study is to employ a user-centered approach to identify subgroups of people with similar profiles based on their perceptions of multiple dimensions of digital products' coolness and to test the differences across subgroups in the intention to use these products.Design/methodology/approachIn Study 1, 1,161 adults rated a virtual digital product on four dimensions of coolness. In Study 2, 660 college students made similar ratings and also reported their intention to use a real digital product. Participants' ratings were analyzed using a user-centered approach, namely latent profile analysis.FindingsStudy 1 identified groups of participants who had similar profiles of product ratings on the four dimensions of coolness: niche cool, mass cool, uncertain cool and uncool. Study 2 replicated the findings of Study 1 and in addition showed that these groups varied in their intention to use the product and in whether a specific dimension increased or decreased this intention.Research limitations/implicationsThe cross-sectional data preclude inferences about causality, calling for experimental or longitudinal research. Additionally, future research should explore whether the results generalize to other product categories and other age groups.Practical implicationsManagers should design digital products, segment the market and develop flexible strategies based on combined responses to dimensions of coolness perception.Originality/valueThe present research employed a user-centered approach to identify groups of people who share similar patterns of coolness perception. This study provides new insight that was not available in variable-centered research.
Acceptance of protection technology in a time of fear: the case of Covid-19 exposure detection apps
Authors: Alsaad Abdallah , Al-Okaily Manaf 
Published: July 2021

PurposeThis study explores the acceptance of protection technology, namely, exposure detection apps, in the context of the Covid-19 pandemic. Unlike other situations, the context of the pandemic is characterized by large levels of threat and fear which largely affect the human decision-making process. To identify such characteristics, this study investigates the acceptance of exposure detection apps from the perspective of protection motivation theory (PMT). It examines how the perceived risk of Covid-19, perceived fear of Covid-19, self-efficacy, response efficacy and protection motivation interact to predict the acceptance of exposure detection apps.Design/methodology/approachData were collected from 306 Jordanian participants, and structural equation modelling was used for data analysis.FindingsThe results reveal that acceptance of these apps is triggered by the perceived risk of Covid-19, which increases the experienced level of fear. The latter then initiates a compelling desire or motivation to protect oneself by using the recommended adaptive response (exposure detection app). The results show that an increased level of self-efficacy and perceived efficacy of exposure detection apps also contribute to the development of protection motivation and later the intent to use exposure detection apps.Originality/valueThis study contributes to the technology acceptance domain by developing a context-driven model of the key characteristics of pandemics that lead to different patterns of technology acceptance. The key components in designing effective marketing campaigns to prompt the use of exposures detection apps are discussed.

Authors: Wibowo Mas Wahyu , Putri Auditia Lintang Sari , Hanafiah Ali , Permana Dudi , Sh Ahmad Fauziah 
Published: July 2021

Purpose
The purpose of this paper is to evaluate Indonesian Muslim millennials’ decision-making process in purchasing halal food by introducing knowledge variable into the theory of planned behavior framework and education level (EL; i.e. low vs high) as the moderating variable.

Design/methodology/approach
There were 400 questionnaires that were distributed to obtain responses from Indonesian Muslim millennials consumers. SmartPLS was used as the structural equation modeling approach to perform the multi-group analysis.

Findings
EL plays an important role that determines Indonesian Muslim millennials’ decision-making process to purchase halal food.

Research limitations/implications
The EL was distinguished based on the Indonesian formal education system, which excluded the religious education system from the analysis.

Practical implications
The information conveyance of halal food product attributes should be conducted gradually according to the millennial consumers’ EL. Millennial consumers with higher EL are more likely to internalize the credence attributes of halal food compared to the lower EL counterpart.

Originality/value
This study found the significant differences in terms of halal food purchase decision-making between the two groups of lower EL and higher EL.
Do Investors Care Who Did the Audit? Evidence from Form AP
Authors: DOXEY MARCUS M. , LAWSON JAMES G. , LOPEZ THOMAS J. , SWANQUIST QUINN T. 
Published: July 2021

ABSTRACTIn early 2017, the Public Company Accounting Oversight Board (PCAOB) mandated the disclosure of audit participants, including the lead audit partner and other audit firms participating in the audit (“component auditors”). In this study, we examine whether investors use these disclosures in a way that influences their investment decisions, a primary goal of the PCAOB. Using trading volume, absolute abnormal returns, and bid–ask spreads, we find little evidence of a significant investor response following the disclosure of partner identity or component auditor participation in the first three years of the requirement. We also examine instances where these disclosures are most likely to be informative (e.g., partners associated with restatements or component auditors with PCAOB deficiencies) and find no significant investor response. Taken together, we find little evidence that capital markets respond to partner and component auditor identity in the United States.
Trading‐off flexibility: Contingent workers or human resource practices? A configurational approach
Authors: Signoretti Andrea , Pederiva Lucia , Zaninotto Enrico 
Published: July 2021

AbstractAtypical work has been proven to worsen employment conditions, reduce labour productivity and hinder firms from competing in higher quality market segments, yet companies still hire atypical workers to provide flexibility in response to unstable market conditions. Previous research has examined the relationship between specific job features and the incidence of atypical work. Using a fuzzy‐set qualitative comparative analysis technique, we analysed interviews of service firms’ managers to identify configurations that limit the use of atypical workers. We found evidence that firms limit the use of atypical contracts not only in cases of firm‐specific and complex tasks but also in cases of simple and nonspecific tasks when supported by human resource management practices that aim to increase internal flexibility. Firms can take advantage of a stable workforce by strategically using human resource management flexibility practices as an alternative to labour market flexibility.
