Authors: Long Risheng , Zhao Chao , Jin Zhihao , Zhang Yimin , Pan Zhen , Sun Shaoni , Gao Weihua 
Published: August 2021

PurposeThe purpose of this paper is to reveal the friction and wear performance of grooves textured cylindrical roller thrust bearings with different groove dimensions under starved lubrication.Design/methodology/approachThe groove dimensions include: width of grooves (WOG, 50 µm, 100 µm and 150 µm), depth of grooves (DPOG, 7 µm, 11 µm and 15 µm) as well as groove deflection angle (GDA, 45°). A fiber laser marking system was used to prepare groove patterns on the raceways of shaft washers. The friction and wear properties of grooves textured bearings were researched through a vertical universal wear test rig using a customized roller bearing tribo-pair under starved lubrication. Static finite element analyses were conducted to reveal their surface stresses. Through the comprehensive comparison and analyses, the influence mechanism of grooves on the tribological behavior of cylindrical roller thrust bearings was proposed and discussed.FindingsWhen grooves textured bearings run under starved lubrication, their average coefficients of friction (COFs) and wear losses are all significantly reduced and much lower than those of smooth group. The influence of DPOG on the COF curves is significant, while the influence of WOG on the COF curves is a little weak. The influence of groove dimensions on the surface stresses of grooves textured bearings is weak, whether the WOG or DPOG. In this work, when the WOG is 100 µm and the DPOG is 15 µm, its average COF and wear loss are both the lowest, 0.0066 and 0.61 mg, respectively. Compared with the data of smooth group, its friction coefficient is reduced by 75.3% and its mass loss is reduced by 95.8%, showing a significant improvement in this condition.Originality/valueThis work can provide a valuable reference for the raceway design and reliability optimization of rolling element bearings.

Authors: de Souza João Pedro C. , Amorim António M. , Rocha Luís F. , Pinto Vítor H. , Moreira António Paulo 
Published: August 2021

Purpose
The purpose of this paper is to present a programming by demonstration (PbD) system based on 3D stereoscopic vision and inertial sensing that provides a cost-effective pose tracking system, even during error-prone situations, such as camera occlusions.

Design/methodology/approach
The proposed PbD system is based on the 6D Mimic innovative solution, whose six degrees of freedom marker hardware had to be revised and restructured to accommodate an IMU sensor. Additionally, a new software pipeline was designed to include this new sensing device, seeking the improvement of the overall system’s robustness in stereoscopic vision occlusion situations.

Findings
The IMU component and the new software pipeline allow the 6D Mimic system to successfully maintain the pose tracking when the main tracking tool, i.e. the stereoscopic vision, fails. Therefore, the system improves in terms of reliability, robustness, and accuracy which were verified by real experiments.

Practical implications
Based on this proposal, the 6D Mimic system reaches a reliable and low-cost PbD methodology. Therefore, the robot can accurately replicate, on an industrial scale, the artisan level performance of highly skilled shop-floor operators.

Originality/value
To the best of the authors’ knowledge, the sensor fusion between stereoscopic images and IMU applied to robot PbD is a novel approach. The system is entirely designed aiming to reduce costs and taking advantage of an offline processing step for data analysis, filtering and fusion, enhancing the reliability of the PbD system.
A constructivism-based training course for hospitality and tourism instructors in Vietnam to improve their self-confidence in synchronous online teaching
Authors: Luong Thanh-Thao , Kim Eunyoung 
Published: August 2021

Purpose
As Vietnam needs to shift from physical to virtual classrooms owing to the coronavirus disease 2019 (COVID-19) pandemic, this study aims to propose and evaluate a constructivist training course designed to improve instructors’ self-confidence in conducting synchronous online teaching by helping them develop the skills required for such.

Design/methodology/approach
A total of 67 in-service instructors in various hospitality and tourism institutions in Vietnam participated in the proposed course. Constructivist approaches were adopted to design learning activities. Delivered via Blackboard Collaborate’s classroom version, the course aims at enhancing instructors’ self-confidence in the knowledge and skills required for synchronous online teaching: developing online presence, planning lessons, handling technology, adapting to learners’ preferences and classroom management. Using qualitative and quantitative analyses, this paper evaluated the proposed course by comparing participants’ levels of self-confidence in conducting synchronous online teaching before and after the training.

Findings
The results show that participants’ self-confidence was enhanced after the course. To improve the course, however, more time should be allotted for practice sessions where participants can pedagogically and technologically familiarize themselves with online teaching tools.

Originality/value
By translating constructivism into online pedagogy, this study provided empirical evidence of how a teachers’ training program was designed and implemented to meet the need to shift from real-life to real-time classrooms in Vietnam during the COVID-19 pandemic. It also contributes to the growing literature on methods of improving instructors’ readiness in synchronous online teaching.

Published: August 2021

Purpose
The purpose of this study is to investigate the factors that affect students’ behavioral intentions to use virtual classrooms at Princess Sumaya University for Technology (PSUT) in Jordan.

Design/methodology/approach
A quantitative research approach was adopted, an online survey method was used and the data were collected among students at PSUT in Jordan. A total of 511 responses were usable for analysis. A structural equation modeling partial least squares technique was used to examine the hypothesized model.

Findings
The findings reveal that the proposed factors have direct and indirect relationships with behavioral intentions to use virtual classrooms. They show that students’ satisfaction has a direct influence on behavioral intention, while other variables such as instructor characteristics, virtual classroom quality, perceived self-efficacy, perceived organizational support, perceived ease of use and perceived usefulness have an indirect effect on behavioral intentions to use virtual classrooms.

Research limitations/implications
The study was conducted at PSUT in Jordan, which could limit the generalizability of the findings. Furthermore, the present study measured students’ behavioral intentions to use virtual classrooms and future research should consider the actual use of virtual classrooms.

Practical implications
The findings of this study offer significant and useful information to policymakers, instructors, developers and students regarding the use of virtual classrooms in universities. Based on students’ needs and readiness, the findings identify which factors to consider when developing an e-learning system to enhance learning and teaching performance.

Originality/value
This study extends existing knowledge by developing a conceptual model to identify the key factors of virtual classroom adoption in higher education institutions in Arab countries. This study contributes to the literature in the context of e-learning by validating an extended technology acceptance model from an Arab countries perspective and considering the differences in culture, learning style and physical environment compared to developed countries.

Authors: Lee Minwoo 
Published: August 2021

Purpose
Information and communication technologies have been widely implemented and made radical changes for several decades in the hospitality and tourism industry. This rapid development also generates considerable data in social media. This trend opens the door to analyze unstructured data and gain increased attention of a qualitative research approach from hospitality and tourism researchers and industry professionals. Therefore, this paper aims to describe how a computer-assisted qualitative data analysis (CAQDA) approach can be used in the hospitality and tourism technology literature to uncover the trends and thematic concepts of hospitality and tourism technology research and their dynamics in Journal of Hospitality and Tourism Technology (JHTT)

Design/methodology/approach
To achieve the proposed research goals, the current study used CAQDA software, Leximancer, to analyze 218 articles published in JHTT between Volume 1(1) in 2010 and Volume 10(4) in 2019. Based on the rigorous CAQDA processes, the study performed the thematic analysis using all articles and subgroup analyses in the five-year periods.

Findings
Using CAQDA, the study reveals the critical research trends and insights on hospitality and tourism technology for 10 years in the JHTT. The findings of this study can provide strong evidence of what hospitality and tourism technology research topics have been examined and how these topics were connected and changed over time. More importantly, the current study illustrates how the CAQDA approach can be applied to uncover the hidden trends and thematic concepts from text data in the hospitality and tourism literature.

Originality/value
This study is the first attempt to apply CAQDA software to identify research trends and thematic concepts and gain insights from past JHTT’s articles. Moreover, this study applies this software to describe how hospitality and tourism researchers can use one of the modern computer-assisted qualitative techniques. Based on the findings of this study, theoretical and methodological implications for hospitality and tourism researchers are provided. More importantly, the current study presents the specific guidelines of how the CAQDA approach can be used for the literature review.
Team reflexivity, individual intellectual capital and employee innovative behavior: a multilevel moderated mediation
Authors: Wang Zhining , Cui Tao , Cai Shaohan , Ren Shuang 
Published: August 2021

PurposeBased on experiential learning theory (ELT), this study explores the cross-level effect of team reflexivity on employee innovative behavior. The authors especially focus on the mediating effect of individual intellectual capital (IIC) and the moderating effect of empowering leadership on the relationship between the two constructs.Design/methodology/approachThis study collects data from 76 work units, which include 362 employees and their direct supervisors. A cross-level moderated mediation model was tested by using multilevel path analysis.FindingsThe results show that team reflexivity significantly contributes to employee innovative behavior. IIC mediates the above relationship. Empowering leadership not only positively moderates the relationship between team reflexivity and IIC but also reinforces the linkage of team reflexivity → IIC → employee innovative behavior.Practical implicationsThe study suggests that organizations should invest more in promoting team reflexivity and empowering leadership in the workplace. Furthermore, managers should make members aware of the importance of IIC for employee innovative behavior. They need to make efforts to enhance IIC via internal communication channels or open discussions, which facilitate IIC and employee innovative behavior.Originality/valueThis research tests the relationship between team reflexivity and employee innovative behavior and identifies IIC as a key mediator that links team reflexivity to employee innovative behavior. It also highlights the moderating role of empowering leadership in the process.
An imitation game – supervisors’ influence on customer sweethearting
Authors: Ertz Elias , Becker Laura , Büttgen Marion , Izogo Ernest Emeka 
Published: August 2021

PurposeCustomer sweethearting is a common illicit behavior of frontline employees in service firms. This paper aims to examine the impact of supportive–disloyal leadership behavior on customer sweethearting at different levels of leader–member exchange (LMX) quality.Design/methodology/approachDrawing on imitation theory and need-to-belong theory, the paper builds a conceptual model and empirically tests it using data from a survey-based study and a complementary experiment.FindingsThe authors find that employees’ customer sweethearting is affected by their supervisors’ supportive–disloyal behavior (employee sweethearting) through two divergent paths: employees imitate the sweethearting behavior of their supervisors; and employee sweethearting triggers employees’ feelings of belongingness to their organization, which reduces their customer sweethearting behavior.Practical implicationsThe findings suggest that service firms can mitigate customer sweethearting by raising awareness that supervisors act as negative role models to subordinates and fostering high-quality LMX relationships, which give employees a sense of belonging to the supervisor and the organization.Originality/valueBy taking supervisors’ supportive–disloyal leadership behavior as an ambivalent driver of customer sweethearting into account, this paper provides further insight into the occurrence of customer sweethearting, particularly its underlying contrasting psychological mechanisms.
The interplay between brand and business model architectures:a conceptual grid
Authors: Logman Marc 
Published: August 2021

PurposeThis conceptual paper studies how brand and business model architectures interact.Design/methodology/approachConfronting the literature on brand and business model architectures, a “problematizing review” perspective is taken in this article. To develop the conceptual framework, a cyclical process of theory generation based on a literature review and empirical evidence is used. Various interaction options between a brand and business model architecture are discussed in detail and illustrated with practical examples.FindingsThe conceptual grid allows positioning each brand and business model architectural move in a coherent way, emphasizing the alignment challenges of each positioning option. This study also sheds another light on “dynamic capabilities,” as companies not only need to mix, remix and orchestrate business model architecture decisions, but at the same time align these decisions with brand architecture decisions.Originality/valueBy confronting and integrating two research domains, a novel higher-order theoretical perspective is obtained. In this sense it contributes to a management school of thought that is more integrative and deals better with today's more complex and dynamic reality, in which business model and brand decisions cannot be taken independently.

Published: August 2021

Purpose
China after 1949, especially since entering the 21st century, significant progress has been made in leadership research under Chinese context. However, so far there has been no systematic review and prospect of China's leadership research in the past 70 years. Therefore, with the help of scientific visualization software Citespace, this paper analyzes the research papers on leadership in the context of China from the top international journals of management science and applied psychology (1949–2018), supplemented and verified the previous research conclusions based on qualitative review, and quantitatively demonstrated the research evolution of leadership field.

Design Methodology Approach
Using a scientific visualization tool CiteSpace and 145 international leadership works, which were published in 64 top international journals and collected from the Web of Science database, and 852 domestic works which were published in 28 top domestic journals and collected from the CNKI database from 1949 to 2018, we draws keyword co-occurrence knowledge graph and keyword strategy map to visualize the landscape and evolution of leadership research and analyze the hot topics and research trends in the field of leadership.

Findings
The research found that: (1) Before 2002, there were only 7 articles published in 64 international top journal, mainly focusing on Western leadership theories such as transformational, cross-cultural comparison and the adaptability in Chinese context; (2) From 2003 to 2012, scholars had begun to introduce mainstream quantitative research paradigm in international academic community; (3) From 2013 to 2018, researches tended to be synchronized, with 461 and 99 papers published respectively. How emerging leaderships (such as ethical leadership) affect on various emerging outcome variables (such as creativity, voice behavior, unethical pro-organizational behavior etc.) is hot topic for future research.

Originality Value
Different from the previous qualitative reviews on organizational culture research, this paper, for the first time, uses bibliometric research methods to systematically analyze the evolution path of leadership research during the 70 years of China(1949–2018, and puts forward the future research prospects.
Exploring financial risks disclosure: evidence from Indian listed companies
Authors: Khandelwal Chandani , Kumar Satish , Verma Deepak 
Published: August 2021

PurposeThe purpose of this paper is to contribute to the existing literature on financial risk disclosure by examining a sample of non-financial Indian companies listed on the Bombay stock exchange (BSE) to explore the degree of information about financial risks contained in their annual reports.Design/methodology/approachTo study the financial risk disclosure of Indian companies, a sample of 206 non-financial companies has been derived from the top 500 listed companies at BSE. The method used in this study to analyze risk disclosure is content analysis. A total of 1,854 annual reports are scanned through software Nvivo-12 to find different types of risk words. Overall, risk disclosure, category wise risk disclosure, year-wise risk disclosure and sector-wise risk disclosure are assessed. The risk disclosure index is also computed.FindingsThe results show that there are some risk disclosure practices in Indian companies. No general pattern is observed. Companies are following vague method of risk disclosure. In the true sense, Indian companies are now started risk disclosure practices since 2018. This may be because of pressure from regulating bodies and stakeholders with greater detail about their financial risks.Originality/valueThis study is carried out for Indian non-financial companies. The paper adds to the literature relating to financial risk disclosure in developing countries.
More is none? Exploring how SMEs describe their best practices in performance measurement
Authors: Tam Steven 
Published: August 2021

Purpose
This paper aims to provide owner/managers with access to an evidence-based study for the purpose of improving practice in performance measurement (PM) in their small and medium-sized enterprises (SMEs).

Design/methodology/approach
As a qualitative case study, it adopted semi-structured interviews to explore the best practices in PM from 32 SMEs in Malaysia. The interviewees were the owner/manager, the supervisor and/or the person who is responsible for human resources in the firm. Thematic analysis was conducted.

Findings
First, it should be no surprise, as the study echoes previous research, that the traditional, complex PM systems are not functionally suitable for most SMEs. Second, the study identifies five common capabilities (5Cs) in human capital that these SMEs require in their PM practice, all of which are claimed to contribute critically to SME success and sustainability.

Research limitations/implications
While qualitative studies can obtain in-depth results, it is encouraged to continue similar research with additional samples for comparison, including quantitative studies and SMEs in other countries.

Practical implications
The findings help SME owners/managers benchmark their current practices in PM and improve toward what peer firms have been doing well to benefit organizational development in a feasible tone.

Originality/value
This research informs SME practitioners of the 5Cs mechanism found to be effective for long-term organizational survival – including during unprecedented times such as an economic downturn or a pandemic.
Does emotional media content increase donations for rejected groups?
Authors: Zuniga Huertas Melby Karina , dos Santos Fernandes Cavalcanti Paula , Torres Urdan André 
Published: August 2021

Purpose
The purpose of this paper is to analyze the effect of exposure to prosocial media content (PMC) on the subsequent intention to donate to a prosocial cause of a rejected group versus a prosocial cause of a neutral group. The hypothesis, supported in two experimental studies, is that for the individual exposed to a PMC, the difference in the donations for social causes of a rejected group and a neutral group is smaller than for the individual exposed to a non-PMC.

Design/methodology/approach
Two between-subjects experimental studies were performed. In both studies, the individual’s emotional responses were manipulated through PMC (conditions: prosocial versus non-prosocial). Then, respondents were asked to split a fixed amount of money between two social actions whose beneficiaries were members of a rejected group versus members of a neutral group.

Findings
It was found that the difference in donation between the two actions associated with different types of beneficiaries (i.e. rejected group vs neutral group) was smaller for the individuals exposed to PMC than for individuals exposed to non-PMC.

Research limitations/implications
In this research, the donating behavior was operationalized by a simulated donation and not by a real donation.

Practical implications
Results suggest that PMC on the internet could be effective in reducing rejection for stigmatized dissociation groups for which it is difficult to get help.

Social implications
The results suggest that exposure to PMC on the internet can increase donations for rejected groups. The confirmation of the PMC effect on reducing negative outcomes opens the possibility to diminish negativity toward stigmatized groups.

Originality/value
Theoretically, the explanations are based on the social comparison theory.
