Authors: Ullah Basharat , Khan Faisal , Khan Bakhtiar , Yousuf Muhammad 
Published: January 2022

Purpose
The purpose of this paper is to analyze electromagnetic performance and develop an analytical approach to find the suitable coil combination and no-load flux linkage of the proposed hybrid excited consequent pole flux switching machine (HECPFSM) while minimizing the drive storage and computational time which is the main problem in finite element analysis (FEA) tools.

Design/methodology/approach
First, a new HECPFSM based on conventional consequent pole flux switching permanent machine (FSPM) is proposed, and lumped parameter magnetic network model (LPMNM) is developed for the initial analysis like coil combination and no-load flux linkage. In LPMNM, all the parts of one-third machine are modeled which helps in reduction of drive storage, computational complexity and computational time without affecting the accuracy. Second, self and mutual inductance are calculated in the stator, and dq-axis inductance is calculated using park transformation in the rotor of the proposed machine. Furthermore, on-load performance analysis, like average torque, torque density and efficiency, is done by FEA.

Findings
The developed LPMNM is validated by FEA via JMAG v. 19.1. The results obtained show good agreement with an accuracy of 96.89%.

Practical implications
The proposed HECPFSM is developed for high-speed brushless AC applications like electric vehicle (EV)/hybrid electric vehicle (HEV).

Originality/value
The proposed HECPFSM offers better flux regulation capability with enhanced electromagnetic performance as compared to conventional consequent pole FSPM. Moreover, the developed LPMNM reduces drive storage and computational time by modeling one-third of the machine.
Experimental investigation and comparative study of signal processing techniques dedicated for the diagnosis of rotor failures in the induction motors
Authors: Dehina Wissam , Boumehraz Mohamed , Dehina Wissam , Kratz Frédéric 
Published: January 2022

Purpose
The purpose of this paper is to propose applications of advanced signal-processing techniques for the diagnosis and detection of rotor fault in an induction machine. Two techniques are used: spectral analysis techniques and time frequency techniques for the diagnosis of an electrical machine. One is based on the power spectral density estimation techniques, such as periodogram and Welch periodogram. The second method is based on Hilbert transform (HT) to extract the envelope for the stator current. Then, this signal is processed via discrete wavelet transform (DWT) for determining the faulty components in the spectrum of the stator current envelope and identifying the eigenvalues of energies (HDWT).

Design/methodology/approach
First, this paper focused on theoretical development and a comparative study of these signal-processing techniques, which are based on the periodogram, Welch periodogram, HT and the DWT to extract the envelope for the stator current; it is used to compute the energy stored in each decomposition level obtained by the stator current envelope (HDWT). Moreover, the Welch periodogram is applied to obtain the envelope spectrum.

Findings
The simulation obtained and the experimental validation results of the proposed methods through MATLAB environment show the effectiveness of the proposed approaches with a good accuracy by power spectral density estimation techniques (periodogram and Welch periodogram). Moreover, the faults are manifested through the appearance of new frequencies components, as well as the envelope for the stator current (HT and DWT). This approach is effective for non-stationary and stationary signal to extract useful information for the detection of broken bar fault.

Originality/value
The current paper proposes a new diagnosis method for the detection and characterization of broken rotor bars defects early; it is founded primarily on theoretical development, and the comparison is based on the power spectral density technique (periodogram and Welch periodogram) and the computation of the energy stored in each decomposition level (precisely the HT and DWT). Moreover, the Welch periodogram is applied to obtain the envelope spectrum. The main advantages of the proposed techniques increase their reliability and availability.
Searching for hedging and safe haven assets for Indian equity market – a comparison between gold, cryptocurrency and commodities
Authors: Bandhu Majumder Sayantan 
Published: January 2022

Purpose
This paper aims to evaluate the hedging and safe haven properties of gold, cryptocurrency and commodities against the Indian equity market.

Design/methodology/approach
First, the authors estimate the hedging and safe haven abilities of gold, cryptocurrency and commodities for the Indian stock market and further verify whether such properties vary across the broad stock market indices and over the different degrees of market volatility. Second, the authors use the multivariate GARCH framework to calculate the dynamic hedge ratios and hedging efficiencies to compare the hedging properties of the alternative asset classes. Third, the authors verify the robustness of the general findings during the recent crisis emanating from the outbreak of the COVID-19 pandemic.

Findings
Gold, cryptocurrency and most commodities have significant hedging abilities. Only natural gas, crude oil and aluminum, on the other hand, have safe haven property. Neither gold nor cryptocurrency qualifies as a safe haven asset. On the other hand, the financialization of the Indian commodities market provides a significant dividend to investors in terms of hedging and safe haven capabilities. The authors find the least negative hedge ratio and the highest positive hedging effectiveness for the stock-crude oil and stock-natural gas portfolios. The central observations of the paper remain immune to the COVID crisis.

Originality/value
Focusing on the Indian equity market, the paper compares the diversification abilities of traditional assets like gold with those of the modern class of assets, including cryptocurrency and other commodities.
Consumer intentions, reactance and the marketing implications of policy induced mergers and acquisitions in financial services
Authors: Mensah Kobby , Madichie Nnamdi O. , Mensah Gilbert Kofi , Awini Gideon 
Published: January 2022

PurposeThe purpose of this study is to establish, drawing upon the indirect effects of customer reactance from an emerging economy perspective, the marketing implications of policy induced Mergers and Acquisitions (M&A) in Financial Services.Design/methodology/approachThe study employed a quantitative research approach, relying on data from 517 customers of M&A banks in Ghana. Purposive sampling technique was used in selecting respondents for the study. Hypotheses were tested using a structural equation modelling.FindingsA positive and significant relationship between immersive marketing communication and consumer intention is revealed in the study. The presence of consumer reactance highly influenced the relationship. As a public policy tool, forced mergers and acquisitions was found to increase customer reactance. However, when customers are frequently engaged with relevant and consistent marketing communications through appropriate channels, such reactance would only be partial.Research limitations/implicationsAlthough some of the information were collected, they were not the main focus of our analysis. We acknowledge, from the sample demographics perspective, the study did not consider certain other confounding factors that could influence customers' decisions to remain or switch such as customers' level of banking, type of account, income level, banking experiences in relation to service fees, online banking etc., as these could also potentially influence customers' reactance. Perhaps these may have to be considered in future studies.Social implicationsWhen timely and relevant marketing communications are targeted at the customers who are directly impacted by the M&A process, they would experience reactance, but only partially. This has a range of marketing implications for policy-induced M&A and its impact on consumer intention, reactance and attitudes towards the new entity.Originality/valueThe marketing of financial services literature has been silent on the implications of M&A from a policy induced perspective. This study, therefore, contributes to theory by highlighting that the “destruction” of brand value of the affected firms is relatively high in a policy induced M&A and thus increases the level of customer reactance. This is because a regulator enforced M&A, as public policy, usually generates high public interest and public discourse, leading to a heightened customer reactance. However, when immersive marketing communications are targeted at the customers directly impacted by the M&A, they would experience reactance, but only partially.
The causative relationship between natural resource rent and economic growth: evidence from Ghana’s crude oil resource extraction
Authors: Adabor Opoku , Buabeng Emmanuel , Fosua Dunyo Juliet 
Published: January 2022

Purpose
While the relationship between natural resource rent and economic growth is well documented in the literature, not much robust analysis has been done to estimate the causative relationship between oil resource rent and economic growth in Ghana. This might be due to the fact that commercial production of crude oil started not long ago in Ghana. This paper aims to examine the causal relationship between oil resource rent and economic growth for the period of 2011 to 2020 in Ghana.

Design/methodology/approach
The study incorporates economic growth as a function of oil resource rent, non-oil revenue, foreign direct investment, capital and interest rate in a Cobb–Douglass production function/model. The study used four different estimation strategies including the autoregressive distributed lags model, Toda–Yamamoto test approach, nonlinear autoregressive distributed lags model and nonlinear Granger causality.

Findings
The main finding revealed that 1% increase in oil resource rent generates 0.84% increase in economic growth of Ghana in the long run. Contrary, the authors find an insignificant positive effect of oil resource rent on economic growth of Ghana in the short run for the period under study. The result from the Toda–Yamamoto test approach also showed a unidirectional causality running from oil resource rent to economic growth of Ghana, providing evidence in support of the resource blessing hypothesis in Ghana. The results are robust to two different alternative estimation strategies.

Originality/value
The causal relationship between crude oil resource rent and economic growth is examined.
Eliciting preference for private health services among patients in Iran: evidence from a discrete choice experiment
Authors: Ansari Fahimeh , Rafiei Sima , Kakemam Edris , Amerzadeh Mohammad , Ahadinezhad Bahman 
Published: January 2022

Purpose
The provision of private health-care services by public hospitals is common in Iran. Examining factors associated with patients’ preferences to use private health services and using this knowledge in health planning and policymaking can help expand the use of such services. Thus, this study aims to investigate patients’ preferences for private health services delivered in public hospitals.

Design/methodology/approach
Based on a discrete choice experiment from a sample of 375 patients in a public training hospital in Qazvin, northwest city of Iran, the authors evaluated participants’ preference over the health-care attributes affecting their choice to use private health-care services delivered in the hospital. The authors also estimated the marginal willingness to pay to determine the maximum amount a patient was willing to pay for the improvement in the level of each health-care attributes.

Findings
The findings revealed that patients were 2.7 times more likely to choose private hospital services when the waiting time was reduced to less than a week. Furthermore, as patients had complimentary insurance coverage, they were over 60% more likely to receive such services from training hospitals. Finally, continuity of care and reduced health-care tariffs were significant factors that increased patients’ preference to choose private services by 52 and 37%, respectively.

Originality/value
Examining factors associated with patients’ preferences to use private health services and using this knowledge in policymaking can help expand such services. The findings affirmed that various incentives, including service quality factors, are required to increase the likelihood of patients choosing private services.
Assessing the Livelihood Empowerment Against Poverty (LEAP) program as a conditional income transfer: a search for a conceptual framework
Authors: Karakara Alhassan Abdul-Wakeel , Ortsin Ernest Amoabeng 
Published: January 2022

PurposeGhana has implemented different kinds of pro-poor program and policies since its independence to reduce poverty. The Livelihood Empowerment Against Poverty (LEAP) is one of such program. LEAP is a social cash transfer program and its implementation has been under the auspices of the Ministry of Gender, Children and Social Protection since 2008. It provides direct cash and health insurance coverage for extremely poor households across the country to alleviate short-term poverty and encourage long-term human capital development. This paper examines the LEAP program in terms of how it has achieved its aim and the opportunities for improvement.Design/methodology/approachPrimary data were obtained from interviews of 110 beneficiaries of the program. The study proposes a conceptual framework that links poverty reduction and social policies to assist researchers analyze pro-poor or social cash transfer program.FindingsThe findings show that the program is challenged with administrative bureaucracies, irregular inflow of funds, perceived political interferences, inconsistent implementation strategies and low value of the cash transfer (which results in little or no impact on consumption). However, the data also show that LEAP has positive impacts on nonconsumption spending like children's schooling. The program' exit strategy does not impact much on beneficiaries to allow them exit without the tendency of being poor.Practical implicationsThis paper discussed the LEAP program as a social cash transfer to the poor in Ghana. The study constructed a conceptual framework to help researchers and practitioners analyze the implementation of pro-poor interventions. This conceptualization allows for cash transfer program to empower beneficiaries and exits them to allow for other beneficiaries to enroll, ensuring reduction in poverty over time. Generally, the beneficiaries have benefited from the LEAP in the areas of consumption, education and healthcare with few beneficiaries being able to accumulate some few assets. The LEAP program has no exit plan.Originality/valueThis study adds to literature by offering a conceptual framework to help researchers and policy makers in dealing with social assistance policies to the poor. The study also gave an insight into how pro-poor policy strategies could be crafted.

Authors: Tan Kai , Postel Victor , Liu Yujia , Yang Dongtong , Tang Sen , Wang Chong , Wang Qingyuan 
Published: January 2022

PurposeMechanical issues related to the information and growth of small cracks are considered to play a major role in very high cycle fatigue (VHCF) for metallic materials. Further efforts on better understanding in early stage of a crack are beneficial to estimating and preventing catastrophic damage for a long period service.Design/methodology/approachDependent on the ultrasonic loading system, a novel method of in situ photomicroscope is established to study the crack behaviors in VHCF regime.FindingsThis in situ photomicroscope method provides advantages in combination with fatigue damage monitoring at high magnification, a large number of cycles, and efficiency. Visional investigation with attached image proceeding code proves that the method has high resolution on both size and time, which permits reliable accuracy on small crack growth rate. It is observed that the crack propagation trends slower in the overall small crack stage down to the level of 10–11 m/cycle. Strain analysis relays on a real-time recording which is applied by using digital image correlation. Infrared camera recording indicates the method is also suitable for thermodynamic study while growth of damage.Originality/valueBenefiting from this method, it is more convenient and efficient to study the short crack propagation in VHCF regime.
The determinants of the link between life satisfaction and job satisfaction across Europe
Authors: Soboleva Natalia 
Published: January 2022

PurposeThe purpose of this paper is to explore the effect of work values and socio-demographic characteristics upon the link between life satisfaction and job satisfaction.Design/methodology/approachThe European Values Study (EVS) 2008–2009 is used as the dataset. The sample is limited to those who have paid jobs (28,653 cases).FindingsSocio-demographic characteristics matter more than work values in explaining the effect of job satisfaction on life satisfaction. The association between life satisfaction and job satisfaction is stronger for higher educated individuals and those who are self-employed and weaker for women, married individuals, religious individuals and those who are younger. Extrinsic and intrinsic work values significantly influence life satisfaction independent of the level of job satisfaction.Practical implicationsIt is important to pay attention to the working conditions and well-being of the core of the labour force, in other words, of those who are ready to invest more in their jobs. Also, special attention should be given to self-employment.Originality/valueThe paper compares the roles of work values and of socio-demographic characteristics as predictors of the association between job satisfaction and life satisfaction. It shows that the role of job in person's life depends largely on demographic factors, religiosity and socio-economic factors.
Effect of laser-textured micro dimples on inhibition of stick-slip phenomenon of sliding guideway
Authors: Fu Yonghong , Yang Jie , Wang Hao , He Yuyang 
Published: January 2022

Purpose
This study aims to investigate the efficacy of micro dimple in inhibiting stick-slip phenomenon on the sliding guideway.

Design/methodology/approach
In this study, micro-dimples were fabricated by laser on surfaces of steel disk and guideway. The disks and guideways were respectively performed pin-on-disk tribological tests and working condition experiments to study differences in lubrication condition and friction stability between textured and untextured surfaces.

Findings
Micro-dimples help reduce critical sliding speed that allows contact surfaces to enter in hydrodynamic lubrication regime. This increases hydrodynamic lubrication range and narrows speed range where stick-slip phenomenon can occur, enhancing sliding guideway’s adaptability for broader working conditions. Furthermore, friction stability on the textured surface improved, lowering the occurrence possibility of stick-slip phenomenon. Finally, difference between static and kinetic frictions on the textured surface is lower relative to the untextured surface, which decreases the critical velocity when the stick-slip phenomenon occurs.

Originality/value
The results indicate that laser-textured micro-dimples are significantly conducive to inhibit stick-slip phenomenon, thus providing smoother movement for the guideway and eventually increasing precision of the machine.
Relationship between personality traits and consumer rationality regarding the intention to purchase collaborative fashion
Authors: Campos Patrícia de Oliveira , Costa Cristiane Salomé Ribeiro , Costa Marconi Freitas da 
Published: January 2022

PurposeThe study aims to identify the antecedents of consumers' collaborative fashion purchase intention by analysing innovativeness, self-confidence and consumer spending self-control variables as antecedents.Design/methodology/approachA descriptive quantitative research was performed to verify the influence of such variables based on data collected through an online survey and analysed by structural equation modelling (SEM), which resulted in a final sample of 230 valid respondents.FindingsThe main findings include innovativeness as a strong antecedent of intention to consume collaborative fashion. However, self-confidence and consumer spending self-control are not related to adopting this consumption format, suggesting that collaborative fashion can promote reverse effects by stimulating excessive consumption.Practical implicationsThe results can assist companies of collaborative fashion to enhance their strategies to attract consumers looking for creative reuse of items, for example, by offering repair, revitalisation services and promoting meetings to share tips on how to reuse items creatively. Companies can also improve communication campaigns by focussing on the product itself, rather than price, which seems to be more effective in the context of collaborative fashion consumption.Originality/valueThe study is amongst the first to analyse the influence of consumers' personality traits towards collaborative fashion consumption and provide the scope with findings on the interrelationship between personality traits and consumer rationality, which can broaden the understanding about the potential rebound effects in this context.
A qualitative investigation of the work-nonwork experiences of dual-career professional couples without children
Authors: Boiarintseva Galina , Ezzedeen Souha R. , McNab Anna , Wilkin Christa 
Published: January 2022

PurposeThis paper aims to investigate the idiosyncratic relationships between work and nonwork among dual-career professional couples (DCPCs) intentionally without children, considering individual members' role salience, nonwork responsibilities and care or career orientation.Design/methodology/approachInterview data from 21 Canadian and American couples (42 individuals) was used to explore the research question: How do DCPCs without children perceive their work-nonwork balance?FindingsDCPCs without children are a heterogenous demographic. Some couples are career oriented, some care oriented, some exhibit both orientations, shaping their experience of work-nonwork balance. Unlike popular stereotypes, they do have nonwork responsibilities and interests outside of their thriving careers. Similar to their counterparts with children, they face conflicts managing work and nonwork domains.Originality/valueBased on theories of role salience, work-nonwork conflict, enrichment and balance, the authors suggest that analyses of work-nonwork balance should include nonwork activities other than child caring. The authors further propose that the experience of the work-nonwork interface varies according to whether couples are careerist, conventional, non-conventional or egalitarian. The study also demonstrates that work-nonwork experiences are relational in nature and should be explored beyond a strictly individual perspective.
