Effects of Cr and Ta additions on microstructure, corrosion-wear and electrochemical performances of laser cladded Fe90-Al2O3 coating in 3.5% NaCl solution
Authors: Yan Hu , Dejun Kong
Published: May 2022

Purpose

This paper aims to investigate the effects of Cr and Ta additions on the friction performance and corrosion-wear mechanism of Fe90-Al2O3 coating in 3.5% NaCl solution.

Design/methodology/approach

Cr and Ta reinforced Fe90-Al2O3 coatings were prepared on Q235 steel by laser cladding. The effects of Cr and Ta addition on the coefficient of friction (COF) and wear rate of Fe90-Al2O3 coating were investigated using a friction tester, and the wear model was established to discuss its corrosion-wear mechanism.

Findings

The average COFs of Fe90-Al2O3, Fe90-Al2O3-10%Cr and Fe90-Al2O3-10%Ta coatings in 3.5% NaCl solution are 0.57, 0.42 and 0.75, respectively, and the corresponding wear rates are 9.42 × 10−7, 5.31 × 10−7 and 7.02 × 10−7 mm3 s−1 N−1, respectively. The corrosion-wear resistance of Fe90-Al2O3-10%Cr coating is the best among the three kinds of coatings, in which the additions of Cr and Ta play a role in solid solution strengthening.

Originality/value

The Fe90-Al2O3 coating was strengthened by the additions of Cr and Ta to improve its corrosion-wear resistance in 3.5% NaCl solution.
Randomized tax deadlines can help economy
Authors: Urenda Julio , Kosheleva Olga
Published: May 2022

Purpose

While the main purpose of reporting – e.g. reporting for taxes – is to gauge the economic state of a company, the fact that reporting is done at pre-determined dates distorts the reporting results. For example, to create a larger impression of their productivity, companies fire temporary workers before the reporting date and re-hire then right away. The purpose of this study is to decide how to avoid such distortion.

Design/methodology/approach

This study aims to come up with a solution which is applicable for all possible reasonable optimality criteria. Thus, a general formalism for describing and analyzing all such criteria is used.

Findings

This study shows that most distortion problems will disappear if the fixed pre-determined reporting dates are replaced with individualized random reporting dates. This study also shows that for all reasonable optimality criteria, the optimal way to assign reporting dates is to do it uniformly.

Research limitations/implications

This study shows that for all reasonable optimality criteria, the optimal way to assign reporting dates is to do it uniformly.

Practical implications

It is found that the individualized random tax reporting dates would be beneficial for economy.

Social implications

It is found that the individualized random tax reporting dates would be beneficial for society as a whole.

Originality/value

This study proposes a new idea of replacing the fixed pre-determining reporting dates with randomized ones. On the informal level, this idea may have been proposed earlier, but what is completely new is our analysis of which randomization of reporting dates is the best for economy: it turns out that under all reasonable optimality criteria, uniform randomization works the best.
Content posted by Spanish automotive sector brands on YouTube: branded content, insights and environmental commitment
Authors: Castelló-Martínez Araceli
Published: May 2022

Purpose

The main objective of this study is to analyze content posted by automotive sector brands on their YouTube channels, identifying the use of a branded content format, the application of insights to creative conceptualization and the dissemination of messages related to messages' environmental commitment.

Design/methodology/approach

A descriptive study was conducted using qualitative content analysis as the methodological approach. The sample is made up of 691 videos posted on YouTube from September 2020 to August 2021 by the ten automotive brands with the biggest advertising budgets in Spain (InfoAdex, 2021).

Findings

The findings reveal a predominance of the advertorial format in content posted on YouTube by automotive sector brands, while the branded content format is less popular. Creative concepts based on insights are rare and limited to videos with an advertisement format. The theme of respect for the environment is used mainly in connection with the discourse on vehicle features and not so much as a commitment by the brand in response to consumer concerns or the changes that the automotive sector is undergoing.

Originality/value

The originality of the study lies in the approach it takes to content posted by automotive brands on YouTube. The paper's contribution is innovative in that the study monitors posts by brands in the sample on YouTube over the course of a year, rather than just during the specific periods when these brands run advertising campaigns.

Published: May 2022

Purpose

The purpose of this paper is to identify the areas and logic of integration of different stakeholders using different methods and to analyse their applicability and challenges in practical projects. The main aim is to describe how these different methods impact value creation.

Design/methodology/approach

Action design research was carried out in a large hospital construction project where the first author acted as an “involved researcher” and the second author acted as an “outside researcher”. Two workshops were organised to evaluate the direct and indirect challenges and benefits of the applied four methods and to explain how different methods enable value creation.

Findings

All the studied methods provide good results in terms of usability and commitment to the aims of the project, thus delivering the direct benefits expected. Process, people and tools logic works well in this case project when applying the methods properly. Significant evidence was provided on secondary deliverables of the methods, and all analysed methods had a significant impact in the area of leading people, clarifying what “focus on people” means and how it is enabled.

Practical implications

Focus on people can be achieved through different operative methods if applied in the right way. It is necessary to select the most suitable methods based on all the direct and indirect deliverables.

Originality/value

This case project offered a platform to analyse integration methods in a real-life project using the collaborative contract method. The authors were able to participate in the analysis by taking action from the very beginning of the project in terms of training, learning, continuous development and coaching of these methods and evaluating the applicability.
Does global value chain position affect innovation performance of China’s high-tech industries?
Authors: Yang Nana , Liu Qiming , Qian Furong , Wang Xinglong
Published: May 2022

Purpose

Because of the rapid progress of global value chains (GVCs), it is worthwhile to study their impact on innovation. This study aims to explore the impact of GVC position of high-tech industries in the developing-country context of China on innovation performance; it also aims to explore the moderating effects of industrial agglomeration (specialization agglomeration and diversification agglomeration) on the relationship between GVC position and innovation performance.

Design/methodology/approach

The study is based on data gathered on Chinese high-tech industries in 30 provinces from the 2005–2015 period. The econometric analysis relies on merged data from the China Premium Database and the Trade in Value Added 2018 Database.

Findings

The regression results show that GVC position of China’s high-tech industries significantly affects their innovation performance, and both specialization agglomeration and diversification agglomeration significantly enhance the positive relationship between GVC position and innovation performance of China’s high-tech industries. After dividing the country into coastal and inland regions, new findings appear.

Originality/value

This study highlights the importance of GVC position and its effect on innovation performance of China’s high-tech industries. It contributes to the literature on the relationship between GVCs and innovation by elaborating on the moderating effects of industrial agglomeration on this relationship.
Effects of rTMS on working memory abilities and time-varying spectrum coherence of LFPS and spikes in rats
Authors: Guo Miao Miao , Wang Tian , Zhai Hao Di
Published: May 2022

Purpose

The purpose of this study was to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) at different frequencies on working memory (WM) and neuroelectric activity in rats.

Design/methodology/approach

Three rTMS protocols involving different frequencies were applied to rats, and 16-channel local field potentials (LFPs) and spikes were recorded from the prefrontal cortex (PFC) of rats in each group during the WM task. First, the behavior of rats during the T-maze task was analyzed, and then, the firing rate of spikes and the energy of the θ-band and γ-band in LFPs when rats performed the WM tasks were calculated. Finally, the spectral coherence between LFPs and spikes was analyzed by wavelet transform.

Findings

The results showed that rats in the stimulation groups needed fewer days than those in the control group to reach the task correction standard during the WM experiment (p < 0.05). High-frequency rTMS increases the firing rate of spikes and the degree of synchronization of LFPs-spikes in the θ-band and γ-band in the WM process.

Originality/value

This study showed that high-frequency rTMS can improve the spatial learning ability of rats, which might be due to the increased neuronal excitability of the PFC and the enhancement of co-coding between different modes of neural signals. This study is helpful for understanding the neuroregulatory mechanism of rTMS and will provide a reference for the selection of a suitable frequency for TMS treatment.

Authors: Yang Xiaorui , Chen Ying , Zhang Yan , Yang Wenrong
Published: May 2022

Purpose

The purpose of this study is to develop a friction-type energy-harvesting device based on magnetic liquids (MLs). This MLs energy-harvesting device combines MLs with a triboelectric nanogenerator (TENG), reducing the friction thermal effect to improve the conversion efficiency and working frequency band.

Design/methodology/approach

First, the motion equation of the MLs is calculated using the Bernoulli and fluid continuity equations. Second, the sloshing process of an ML in a container is simulated using the finite element simulation method, and the magnetic field distribution of the permanent magnet in the MLs is calculated. Then, the output characteristic of the ML-TENG is deduced theoretically, and the influencing factors of the output voltage are analyzed. Finally, the output voltage of the MLs energy-harvesting device was tested experimentally, and the influence of the magnetic field on the output voltage was tested.

Findings

This study proposes a vibration energy harvesting device based on MLs. The output voltage of the device was obtained through simulation and experimental tests, and the effect of the magnetic field on the output voltage was obtained.

Originality/value

This study provides a method to convert vibration energy into electrical energy using the magnetic response and fluid characteristics of MLs, and the availability of the device is verified by simulation and experiment. This energy-harvesting device exhibits less loss and a more sensitive response.
Businesses and their community in times of COVID-19: a stakeholder theory approach
Authors: Ng David Wai Lun , Duarte Alonso Abel , Bressan Alessandro , Vu Oanh Thi Kim , Tran Thanh Duc , Atay Erhan
Published: May 2022

Purpose

The purpose of this study is to build an understanding of how firms operate under the COVID-19 crisis. Specifically, the study examines the significance of firms’ survival for their surrounding community, business–community relations during this severe situation and factors helping firms address this unprecedented challenge. The conceptual tenets of stakeholder theory are considered.

Design/methodology/approach

A qualitative data collection approach was selected, with face-to-face and online interviews undertaken with owners and managers of 33 firms operating in Singapore.

Findings

Firstly, while survival during the current unprecedented crisis is perceived to be most important for the firms’ employees, owners/managers also perceive domino effects on other companies working alongside the participating firms, as well as effects on clients and suppliers. Secondly, increased collaboration with industry, stronger partnerships with suppliers and business partners and closer relationships with staff are highlighted during the crisis. Thirdly, key factors helping firms’ survival in the initial year of the crisis included: a clear goal; a cohesive/nimble staff team; reinventing, adapting and being resilient; and family support and management support.

Originality/value

This study contributes empirically and conceptually to the literature on firm adaptation and firm–community relationships during a severe crisis. Empirically, the findings and related dimensions provide practical guidance concerning the interdependence between firms and their stakeholders. Conceptually, the inductive analysis, which enabled the development of a theoretical framework, illustrates the relationships between the study’s emerging dimensions and those predicated by stakeholder theory, namely, the descriptive, instrumental, normative and managerial.
Oil price shocks and sectoral stocks in Nigeria: how relevant are asymmetry and structural breaks?
Authors: Fasanya Ismail Olaleke , Adekoya Oluwasegun Babatunde , Ajayi Felix Odunayo
Published: May 2022

Purpose

This paper aims to model the relationship between oil price and stock returns for selected sectors in Nigeria using monthly data from January 2007 to December 2016.

Design/methodology/approach

The authors use both the linear (symmetric) autoregressive distributed lag (ARDL) by Pesaran et al. (2001) and non-linear (asymmetric) ARDL by Shin et al. (2014), and they also account for structural breaks using the Bai and Perron (2003) test that allows for multiple structural changes in regression models.

Findings

The results indicate that the strength of this relationship varies across sectors, albeit asymmetric and breaks. The authors identify two structural breaks that occur in 2008 and 2010/2011, which coincidentally correspond to the global financial crisis and the Arab spring (Libyan shutdowns), respectively. Moreover, the authors observe strong support for asymmetry and structural breaks for some sectors in the reaction of sector returns to movement in oil prices. These findings are robust and insensitive when considering different oil proxies. While further extensions can be pursued, the consideration of asymmetric effects as well as structural breaks should not be jettisoned when modelling this nexus.

Originality/value

This study is one of the very few studies that have investigated the sectoral behaviour of stocks to oil price shocks, particularly in Nigeria. This paper contributes to the oil stock literature using the recent technique of asymmetry and also considering the role structural breaks play in the relationship between oil price and stock returns.
Frictional evaluation of halogen-free ionic liquids with low corrosion degree and high decomposition temperature on steel surface
Authors: Wang Feiming , Gao Xing , Zang Shuliang , Yue Shuang
Published: May 2022

Purpose

The purpose of this paper is to investigate the tribological properties, antiwear mechanism and anticorrosion properties of two novel halogen-free borate ionic liquids (ILs) in 500 N base oil.

Design/methodology/approach

Different qualities of borate ILs were added to 500 N, and their tribological properties were tested on a four-ball machine. The tribological properties of the additives were evaluated by measuring the wear scar diameter (WSD) and average coefficient of friction. The antiwear and antifriction mechanism of ILs was analyzed by energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS).

Findings

The corrosion degrees of the two borate ILs 1-butyl-3-octyl-imidazole bis(mandelato)-borate ([OBIM][BMB]) and 1-butyl-3-(3-methoxypropyl)-imidazole bis(mandelato)-borate ([MPBIM][BMB]) are 1b and 1a, respectively, suggesting that they both possess significant corrosion resistance and can effectively protect the steel surface. When the concentration of [OBIM][BMB] and [MPBIM][BMB] is 2.5 Wt.%, the friction coefficient of 500 N is reduced by 37.3% and 26.2%, respectively. According to the analysis of the thermo gravimetric analyzer curves, [OBIM][BMB] and [MPBIM][BMB] decomposed at 369.7°C and 374.3°C, respectively, indicate that two additives both can be applied in higher temperature condition. The results of XPS and scanning electron microscope (SEM) reveal that [OBIM][BMB] and [MPBIM][BMB] both can react with the steel surface, thereby forming chemical films composed of iron oxide, B2O3 and organic N-containing compounds.

Originality/value

Two new environmentally friendly borate ILs were synthesized and their tribological properties in 500 N base oil were investigated for the first time.
Vibration suppression of collaborative robot based on modified trajectory planning
Authors: Tian Yong , Yue Xiang , Wang Lin , Feng Yan
Published: May 2022

Purpose

The paper aims to reduce the low-frequency resonance and residual vibration of the robot during the operation, improve the working accuracy and efficiency. A reduced weight and large load-to-weight ratio can improve the practical application of a collaborative robot. However, flexibility caused by the reduced weight and large load-to-weight ratio leads to low-frequency resonance and residual vibration during the operation of the robot, which reduces the working accuracy and efficiency. The vibrations of the collaborative robot are suppressed using a modified trajectory-planning method.

Design/methodology/approach

A rigid-flexible coupling dynamics model of the collaborative robot is established using the finite element and Lagrange methods, and the vibration equation of the robot is derived. Trajectory planning is performed with the excitation force as the optimization objective, and the trajectory planning method is modified to reduce the vibration of the collaborative robot and ensure the precision of the robot terminal.

Findings

The vibration amplitude is reduced by 80%. The maximum torque amplitude of the joint before the vibration suppression reaches 50 N·m. After vibration suppression, the maximum torque amplitude of the joint is 10 N·m, and the resonance phenomenon is eliminated during the operation process. Consequently, the effectiveness of the modified trajectory planning method is verified, where the vibration and residual vibration in the movement of the collaborative robot are significantly reduced, and the positioning accuracy and working efficiency of the robot are improved.

Originality/value

This method can greatly reduce the vibration and residual vibration of the collaborative robot, improve the positioning accuracy and work efficiency and promote the rapid application and development of collaborative robots in the industrial and service fields.
Media synchronicity in organizational social exchange
Authors: Torro Osku , Pirkkalainen Henri , Li Hongxiu
Published: May 2022

Purpose

The purpose of the paper is to examine how media synchronicity facilitates the emergence of social exchange (i.e. trust and reciprocity) in organizations’ information and communication technology (ICT)-mediated interactions. A model of media synchronicity in organizational social exchange (MSiOSE) is proposed.

Design/methodology/approach

The paper has a design and review approach. The theoretical analysis is based on social exchange theory (SET) and media synchronicity theory (MST).

Findings

The authors propose that, in general, social exchange benefits from both asynchronous and synchronous communication processes. However, media synchronicity has different boundary conditions (i.e. pros and cons) in relation to the emergence of social exchange, determined in accordance with the mutually interacting patterns of trust and reciprocity predicted by SET. The authors provide testable theoretical propositions to support the analysis.

Originality/value

Social exchange is a critical business factor for organizations due to its well-known positive outcomes, such as the strengthening of social ties. The need for successful social exchange in remote work conditions is particularly emphasized. However, with regard to the communication and behavioral patterns that lead to social exchange via ICT, the theoretical understanding is limited. The study reveals previously unmapped heuristics between social exchange and physical media capabilities. Thus, the study's propositions can be used to study and analyze social exchange in the ever-changing media landscape. As a practical contribution, the study helps organizations to improve their communication strategies and use of ICT.
Bourdieusian e-capital perspective enhancing digital capital discussion in the realm of third level digital divide
Authors: Merisalo Maria , Makkonen Teemu
Published: May 2022

Purpose

The purpose of this paper is to create a research framework to scrutinize how individuals' digital technology use produces tangible and intangible outcomes in online (digital) and offline realms.

Design/methodology/approach

The paper applies the Bourdieusian e-capital perspective to create a theory-based framework. The framework was used to guide a survey design to explore women's “social media-assisted reuse” at the micro-scale in Helsinki, Finland.

Findings

The paper argues that a new form of capital emerges when individuals utilize digital technologies in correspondence to their goals to gain added value that would be impossible or significantly more arduous to gain without the digital realm. The survey indicates that the respondents utilize the digital space – set objectives and gain capital-related outcomes – in correspondence to their differing social, economic and cultural positions and related resources in- and outside of the digital realm.

Practical implications

If digital spaces – due to social inequality and underlying power structures – become increasingly stratified, there will be significant impacts on how individuals from differing backgrounds gain accumulated forms of capital through the digital realm. The question is of great importance for battling inequality.

Originality/value

The paper enhances and synthesizes recent discussions on different forms of capital and outcomes of the use of digital technologies and presents a combined “e-capital–digital divide” framework that offers a more complete agenda for investigating the finely nuanced links between the inputs, outputs and outcomes of digital technology use.
Regulating professional identities in the epoch of social media: exploring the process of identity creation for IT workers in India
Authors: Gonibeed Aparna , Saqib Syed Imran
Published: May 2022

Purpose

The paper aims to explore the process of identity regulation and identity creation on social media for employees in the IT sector of India and how this process is different for men and women.

Design/methodology/approach

The study is based on the thematic analysis of in-depth interviews of 31 IT professionals.

Findings

The authors find that identity regulation and identity creation is a complex process when it is mediated on social media as cues and guidelines for professionals are ambiguous. Enriching Ibarra's model of identity creation, the authors find that this process consists of five steps: (1) motivation to build a desirable self, (2) experimenting with identity boundaries, (3) failed identity experiences, (4) active self-regulation and (5) enacting inauthentic selves. The authors further find that this self-regulation for men is driven by the pressure to conform to the identity of an ideal “corporate man”, whereas for women it is driven by the need to conform to societal and cultural expectations.

Practical implications

Since identity regulation is a cognitively demanding process that affects both the productivity and well-being of employees, organisations can proactively help employees manage their social media presence through training and mentorship programmes.

Originality/value

The paper provides an enriched version of Ibarra's (1999) model on identity creation and regulation and highlights the role of gender in the process. The paper is practically relevant as it provides a window into how employees can feel the need to manifest inauthentic selves which is cognitively demanding.
How do infectious diseases affect corporate social responsibility? Evidence from China
Authors: Hoang Huy Viet , Hoang Khanh , Ho Linh Tu , Ha Oanh Kieu
Published: May 2022

Purpose

The recent decades have witnessed the rising frequency and severity of infectious diseases in the international context and their detrimental impacts on the corporate world as a result of growing interconnection among nations. This study aims to examine the effect of previous infectious diseases (H5N1, H1N1 and MERS) on the disclosure of corporate social responsibility (CSR) among listed Chinese firms from 2006 to 2017.

Design/methodology/approach

Firm-level financial and CSR data of Chinese non-financial listed firms are from the China Stock Market and Accounting Research database. The data on corporate governance are collected from Bloomberg financial database. Three infectious diseases under examination are H5N1 (2006–2007), H1N1 (2009–2010) and MERS (2015–2016). This study uses the fixed-effect estimations to account for time-invariant differences among the firms in the sample.

Findings

The results reveal that Chinese firms disclose less CSR information during the time of public health crises, and this impact is more pronounced in small-sized and low-growth firms. Besides, the analysis suggests that Chinese firms are becoming more resilient to infectious diseases.

Research limitations/implications

The findings provide implications for corporate stakeholders to understand corporate policies under uncertainties and inform vulnerable businesses to develop an appropriate CSR strategy in preparation for future health calamities.

Originality/value

This study provides new insights into how businesses react to previous epidemics and pandemics at different scales other than the COVID-19 pandemic. Besides, the findings shed light on the dynamic of firms’ CSR engagement during and after the infectious outbreaks.
Using mobile while shopping in-store: a new model of impulse-buying behaviour
Authors: Aiolfi Simone , Bellini Silvia , Grandi Benedetta
Published: May 2022

Purpose

The purpose of this paper is to develop a comprehensive model of impulse-buying that considers the impact of mobile device use on shopping behaviour as a tool for shopping preparation or as a tool for self-regulation.

Design/methodology/approach

Data were obtained through a single-stage mall intercept survey method using a structured questionnaire involving 406 respondents interviewed after checkout. Data analysis was conducted using a structural equation modelling approach with LISREL 8.8.

Findings

The results support most elements of the hypothesis of the proposed conceptual framework. Specifically, findings show the impact of mobile usage on shopping behaviour, which results in fewer impulse purchases.

Practical implications

The research demonstrates how shoppers using mobile devices in-store felt less of an urge to purchase during shopping, resulting in fewer unplanned purchases. The effects of mobile device use on in-store purchasing decisions are designed to create a new scenario for the practice of shopper marketing, and retailers and manufacturers will have to seek new ways to capture consumers’ attention in-store and to influence shoppers’ perceptions early in the shopping cycle without diminishing the role of in-store marketing levers.

Originality/value

Prior research found the antecedents of impulse-buying in individual characteristics, situational variables and endogenous variables. However, it did not consider mobile pre-shopping factors or mobile usage. Filling the gap in the existing literature, this work sets out to develop a comprehensive model of impulse-buying that considers the impact of mobile usage on shopping behaviour.
Is there a price bubble in the exchange rates of the developing countries? The case of BRICS and Turkey
Authors: Yildirim Hakan , Akdag Saffet , Alola Andrew Adewale
Published: May 2022

Purpose

The last decades have experienced increasingly integrated global political and economic dynamics ranging especially from the influence of exchange rates and trade amid other sources of uncertainties. The purpose of this study is to examine the exchange rate dynamics of Brazil, Russia, India, China, and South Africa (BRICS) and the Republic of Turkey.

Design/methodology/approach

Given this perceived global dynamics, the current study examined the BRICS countries and the Republic of Turkey's exchange rate dynamics by using the United States (US) monthly dollar exchange rate data between January 2002 and August 2019. The price bubble which is expressed as exceeding the real value of assets' prices which is observably caused by speculative movements is investigated by using the Supremum Augmented Dickey-Fuller (SADF) and the Generalized Supremum Augmented Dickey-Fuller (GSADF) approaches.

Findings

Accordingly, the GSADF test results opined that there are price bubbles in the dollar exchange rate of other countries except for the United States Dollar (USD)/Indian Rupee (INR) exchange rate. As the related countries are classified as developing countries in terms of their structure, they are also expectedly the subject of speculative exchange rate movements. Speculative movements in exchange rates may cause serious problems in national economies.

Originality/value

Thus, the current study provides a policy framework to the BRICS countries and the Republic of Turkey.
Halal tourism and coronavirus: understanding the influence of halal reputation and fear of COVID-19 on tourist’s revisit intention
Authors: Wardi Yunia , Trinanda Okki
Published: May 2022

Purpose

The existing halal tourism literature has paid insufficient attention in discussing the COVID-19 protocol as a marketing strategy tool for tourism managers. The COVID-19 protocol is one of the considerations for tourists in determining their destination when the global society enters the new normal era and people start to travel. This study aims to interpret the relationship between halal reputation, fear of COVID-19, COVID-19 protocols and tourist’s revisit intention, as well as to describe and discuss the empirical evidence. This study expands the theory on halal tourism while also offering critical insights into marketing practice in the tourism industry.

Design/methodology/approach

The population of this study was Muslim tourists who have visited West Sumatra before the COVID-19 outbreak. The data were collected online for three months and received 451 responses, but after verification, only 395 respondents could be used for data processing. Hierarchical regression was applied to examine the direct relationship and moderating effect of the studied variables which met the sampling criteria.

Findings

This study proves that halal tourists’ revisit intention is determined by a destination’s halal reputation. Subsequently, halal destinations should increase their reputation as excellent halal tourism providers. Furthermore, the COVID-19 protocol can reduce the fear of tourists visiting a tourist destination. Thus, this study gives some contribution to the tourism sector, especially on halal tourism, COVID-19 fear, and protocols and also tourist’s revisit intention.

Originality/value

This paper explores the adoption of the COVID-19 protocol as a marketing strategy. Furthermore, there are still few papers that discuss the effects of COVID-19 on halal tourism. This paper attempts to fill this gap. This paper expands halal tourism literature by assessing the direct relationship and moderating effect of the variables related to COVID-19 on halal tourists’ revisit intention.
Bridging the regional innovation policy and entrepreneurship: the role of intellectual capital
Authors: Hong Yuxiang , Zhang Mengfan
Published: May 2022

Purpose

This study examines whether the national innovative city pilot policy (NICP) influences urban entrepreneurship (UE). To examine the underlying causal mechanism, this study modeled the city-level intellectual capital index and financing capacity (FC) in the relationship between NICP and UE.

Design/methodology/approach

An empirical model of NICP, intellectual capital, FC and entrepreneurship is conceptualized based on theoretical analysis. Using a quasi-natural experiment of China’s NICP, with a sample of 280 prefecture-level cities in China from 2003 to 2018, propensity score matching with difference-in-differences (PSM-DID) is used to empirically test the NICP’s impact on UE, mediating effects of intellectual capital and moderation effects of FC.

Findings

The results show that the NICP can significantly motivate UE. Intellectual capital plays mediating effects on the relationship between NICP and UE. Moreover, the NICP and intellectual capital’s effects on UE are moderated by FC.

Practical implications

This study provides an important reference for promoting UE through intellectual capital and FC in the construction of the NICP.

Originality/value

This is a pioneering study that develops a theoretical model to incorporate NICP, intellectual capital, FC and UE. This paper applies experimental governance theory in innovative urban scenarios, and verifies its applicability and particularity in the Chinese context.
Detached but not deviant: the impact of career expectations and job crafting on the dysfunctional effects of amotivation
Authors: Masood Huda , Karakowsky Len , Podolsky Mark
Published: May 2022

Purpose

This study aims to investigate the link between amotivation and workplace deviance. The authors further outlined how the relationship between amotivation and deviant behavior can be mitigated via proactive work strategies such as job crafting and career outcome expectations.

Design/methodology/approach

The authors conducted a convergent design, mixed-method study to investigate workplace deviance as an outcome of amotivation or the lack of motivation towards an activity. The quantitative data from cross-sectional surveys entailed 127 respondents. The qualitative data comprised of 25 in-depth interviews. The authors sought insights from individuals' lived experiences to understand how amotivated individuals behave at work.

Findings

The quantitative findings contended a significant relationship between amotivation and organizational deviance. The authors also found evidence for the buffering role of career outcome expectations on amotivation and deviance. Finally, avoidance job crafting has been shown to significantly attenuate the aforementioned relationship. The qualitative study identified three broader themes about amotivated individuals' work outcomes.

Practical implications

Amotivation can arise among individuals who feel trapped in a job they want to exit and can result in a range of dysfunctional outcomes including workplace deviance. While amotivated employees may be hard to flag, employers can keep such individuals from demonstrating workplace deviance through placing interventions such as job crafting and career development programs.

Originality/value

The existing literature on work motivation has predominantly overlooked the role of amotivation in determining employee outcomes. The current research generates a new line of inquiry by identifying workplace deviance as an outcome of amotivation. The authors further highlighted that such dysfunctional outcomes of amotivation can be mitigated by job crafting and career outcomes expectancies.
Which quality determinants cause MOOCs continuance intention? A hybrid extending the expectation-confirmation model with learning engagement and information systems success
Authors: Cheng Yung-Ming
Published: May 2022

Purpose

The purpose of this study is to propose the research model integrating the expectation-confirmation model with the views of learning engagement (LE) and extending DeLone and McLean information systems (IS) success model to examine whether quality determinants as antecedents to students' beliefs can influence students' continuance intention of massive open online courses (MOOCs).

Design/methodology/approach

Sample data for this study were collected from students enrolled in a comprehensive university in Taiwan. A total of 600 questionnaires were distributed, and 363 (60.5%) useable questionnaires were analyzed using structural equation modeling in this study.

Findings

This study proved that students' perceived knowledge quality, system quality, interface design quality, learner–instructor interaction quality, and collaboration quality all positively caused students' perceived usefulness, confirmation and LE in MOOCs, which jointly explained students' satisfaction with MOOCs and subsequently resulted in students' continuance intention of MOOCs.

Originality/value

This study fully evaluates IS-related and interaction-related quality determinants via an understanding of students' state of LE in explaining students' continuance intention of MOOCs that is difficult to expound with only their utilitarian perception of MOOCs. Hence, this study contributes to deep insights into an all-round quality evaluation in the field of MOOCs continuance intention and takes extrinsic and intrinsic motivators into account in the theoretical development of MOOCs continuance intention to acquire a more comprehensive and robust analysis.

Purpose

The paper aims to explore the impact of two types of monitoring mechanisms, namely, Securities and Exchange Commission (SEC) comment letters (CLs) and short sellers, on management’s demand for audit quality.

Design/methodology/approach

Using information on the short interest positions and a panel data of SEC CLs between 2005 and 2015, this study applies logit regression model to estimate the likelihood of hiring Big 4 and industry expert audit firm. This study also applies an ordinary least squares regression technique to estimate audit fees.

Findings

Consistent with disclosure and agency theories, results from empirical analyses provide that management demands higher quality audits measured by higher audit fees, and higher likelihood to hire Big 4 and industry expert audit firm. However, this study finds that the effect varies depending on the specific monitoring mechanisms. Additionally, when both monitoring mechanisms are in place, the SEC CLs drive the overall direction of the demand for audit quality when audit demand is captured by propensity to hire Big 4/industry expert audit firm.

Research limitations/implications

This study provides researchers with enhanced understanding of the factors having effect on the demand side for audit quality. Furthermore, it adds to the stream of literature on economic consequences of SEC CLs and short selling.

Originality/value

To the best of authors’ knowledge, this is the first comprehensive study to document the effect of two types of monitoring mechanisms, namely, SEC CLs and short selling, on the demand for audit quality.
Individual outcomes of employee resource group membership
Authors: Beaver Gregory Robert
Published: May 2022

Purpose

This article illustrates the experiences of employee resource group (ERG) members over a two-year period with the aim of understanding the benefits and risks of membership for sexual minority employees.

Design/methodology/approach

Qualitative interview data were collected from seven lesbian, gay or bisexual ERG members following an extreme case approach at two points in time separated by two years.

Findings

Three themes of outcomes related to ERG membership emerged from the data. Participants reported both benefits and risks associated with the social and career-related consequences of membership. The role that allies play in providing visibility, legitimacy and support to ERG members also emerged and shifted in importance over the two years between interviews, with ally involvement becoming more important to career outcomes over time.

Practical implications

This study illuminates potential consequences of supporting ERGs for minority employees, as well as insight into the role of allies in these groups.

Originality/value

This study contributes to the literature by revealing several individual outcomes of a growing form of diversity management practice: ERGs.
Serving for thriving: a moderated mediation analysis of the relationship between servant leadership and thriving at work
Authors: Jang Soebin , Yoo Sangok , Lee Jin , Lee Yunsoo
Published: May 2022

Purpose

Drawing on the socially embedded model of thriving at work, this study aims to test a moderated mediation model to elucidate the mediating effect of work meaningfulness and the moderating role of perceived interpersonal justice on the relationship between servant leadership and thriving at work.

Design/methodology/approach

Based on a sample of 221 employees from the manufacturing industry in South Korea, a series of hierarchical regression analyses were conducted by using statistical package for the social sciences (SPSS) software. For conducting moderated mediation analysis, the PROCESS macro for SPSS was utilized.

Findings

The findings show that servant leadership significantly relates to thriving at work, and work meaningfulness and perceived interpersonal justice act as a mediating mechanism and a boundary condition, respectively. Based on moderated mediation analysis, the collective effect of servant leadership, work meaningfulness and perceived interpersonal justice on thriving at work were also confirmed.

Practical implications

The findings suggest that organizations should adopt servant leadership to promote employee thriving at work. In doing so, it is important to ensure that employees experience work meaningfulness, and are treated with respect and dignity.

Originality/value

This study extends research on servant leadership, and sheds light on important mechanisms and boundary conditions under which servant leadership promotes thriving at work.
Trust in the police and policing by consent in turbulent times
Authors: Torrible Clare
Published: May 2022

Purpose

This paper aims to explore the potential impact on policing by consent and trust in the police of diminished political and generalised trust.

Design/methodology/approach

This paper draws on a range of academic literature on trust, the legal foundations of policing by consent, police occupational culture, disproportionality and neighbourhood policing.

Findings

An analytical framework is developed by recognising that policing by consent can be conceived as comprising two complementary facets, police state consent and police citizen consent and drawing lose mappings between police state consent and political trust and police citizen consent and generalised trust. This supports the argument that the importance of tackling disproportionality in policing practices and an increased emphasis on neighbourhood policing are not only valuable for reasons recognised in existing literature but also because they may bolster policing by consent in circumstances of reduced political trust and contribute to increased generalised trust across society.

Originality/value

This paper builds upon existing work on trust in the police and policing by consent to give novel insights into the importance of neighbourhood policing and tackling disproportionality. The analytical frame developed also highlights new areas for nuanced research questions in the field of trust and provides grounding from which policy objectives for policing can be developed.
Asymmetric effects of economic policy uncertainty on Bitcoin’s hedging power
Authors: Ali Md Hakim , Schinckus Christophe , Uddin Md Akther , Pahlevansharif Saeed
Published: May 2022

Purpose

Even though Bitcoin has been often labelled as a safe haven asset class in the literature, the influence of economic policy uncertainty (EPU) on the diversifying opportunities offered by Bitcoin in relation to other assets needs to be investigated. This paper aims to investigate how the EPU affects diversification of commodity, conventional, Islamic and sustainable equity returns in relation to its impact on Bitcoin returns.

Design/methodology/approach

The authors use advanced time-series econometrics, namely, multivariate generalized autoregressive conditional heteroscedastic-dynamic conditional correlation and continuous wavelet transformation, for the analysis of the daily returns for the aforementioned assets between 01 August 2011 and 01 September 2019.

Findings

First, the authors found a strong evidence of Bitcoin’s mean reverting trend in the long run while its volatility has decreased significantly since 2013. After separating the EPU into two regimes (high and low), diversification opportunities with Bitcoin seems to disappear in a high EPU period, while the hedging opportunity tends to prevail in a low EPU period for all classes of assets. Importantly, the findings indicate that Bitcoin offers short-term diversification for sustainable and Islamic equity as well as energy stocks during a low uncertainty period. Consequently, in relation to the policy uncertainty, Bitcoin provides similar hedging opportunities than commodities like Gold and Silver. Overall, the study shows that EPU is remarkably important in explaining the average portfolio returns of Bitcoin, suggesting that this indicator can be perceived as a decent explanatory factor for portfolio diversification.

Originality/value

The study significantly extends the empirical literature of Bitcoin’s portfolio diversification by taking EPU into consideration. To the best of authors’ knowledge, this is one of the few studies to investigate the asymmetric effects of US EPU on Bitcoin’s hedging capabilities by taking into account major conventional equity, sustainable equity, Islamic equity, gold, silver and oil.
