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

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

PurposeThe 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/approachThe 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.FindingsThe 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 implicationsIf 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/valueThe 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

PurposeThe 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/approachThe study is based on the thematic analysis of in-depth interviews of 31 IT professionals.FindingsThe 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 implicationsSince 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/valueThe 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

PurposeThe 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/approachGiven 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.FindingsAccordingly, 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/valueThus, 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/valueThis 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

PurposeThis 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/approachThe 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.FindingsThe 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 implicationsAmotivation 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/valueThe 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.
