Abstract
Purpose
Hybrid and virtual work settings offer greater flexibility and autonomy, yet they also have the paradoxical effect of weakening the connection of employees to each other and their identification with the organization. The purpose of this article is to discuss how to manage this paradox effectively.
Design/methodology/approach
Leveraging structural adaptation theory, the authors discuss hybrid and virtual work as one of five dimensions of team interdependence that collectively determine the tightness of coupling between team members.
Findings
The authors propose that the introduction of virtual and hybrid work can lead to a lower sense of belonging and identification with the organization that would need to be counteracted by respective increases in team interdependence in one or several of the remaining dimensions of team interdependence.
Originality/value
The authors apply research on team interdependence to develop a series of practical interventions that can address the Great Resignation. These interventions seek to enhance employees' experiences of belongingness after the shift to virtual and hybrid work. In doing so, the authors provide a toolkit that organizations can leverage to improve their employees' experiences in a post-COVID-19 workplace.

Abstract
Purpose
Polishing is a crucial process in mechanical manufacturing. The use of industrial robots to automate polishing is an inevitable trend in future developments. However, current robotic polishing tools are too large to reach inside deep holes or grooves in workpieces. This study aims to use a pneumatic artificial muscle (PAM) as the actuator and designs a force-controlled end-effector to reach inside the deep and narrow areas in the workpiece.
Design/methodology/approach
This approach first addresses the challenge of converting the tensile force generated by the PAM into pushing force through mechanism design. In addition, a dynamics model of the end-effector was established based on the three-element model of the PAM. A combined control strategy was proposed to enhance force control accuracy and adaptability during the polishing process.
Findings
Experiments were conducted on a robotic platform equipped with the proposed end-effector. The experimental results demonstrate that the end-effector can polish the inner end face of holes or grooves with diameters as small as 80 mm and depths reaching 200 mm. By implementing the combined control strategies, the target force tracking error was reduced by 48.66% compared to the use of the PID controller alone.
Originality/value
A new force-controlled end-effector based on the PAM is designed for robotic polishing. According to the experimental result, this end-effector can polish not only the outer surfaces of the workpiece but also the internal surfaces of workpieces with deep holes or grooves specifically. By using the combined control strategy proposed in this paper, the end-effector significantly improves force control precision and polishing quality.

Abstract
Purpose
Students pursuing different professional courses at the higher education level during 2021–2022 saw the first-time occurrence of a pandemic in the form of coronavirus disease 2019 (COVID-19), and their mental health was affected. Many works are available in the literature to assess mental health severity. However, it is necessary to identify the affected students early for effective treatment.
Design/methodology/approach
Predictive analytics, a part of machine learning (ML), helps with early identification based on mental health severity levels to aid clinical psychologists. As a case study, engineering and medical course students were comparatively analysed in this work as they have rich course content and a stricter evaluation process than other streams. The methodology includes an online survey that obtains demographic details, academic qualifications, family details, etc. and anxiety and depression questions using the Hospital Anxiety and Depression Scale (HADS). The responses acquired through social media networks are analysed using ML algorithms – support vector machines (SVMs) (robust handling of health information) and J48 decision tree (DT) (interpretability/comprehensibility). Also, random forest is used to identify the predictors for anxiety and depression.
Findings
The results show that the support vector classifier produces outperforming results with classification accuracy of 100%, 1.0 precision and 1.0 recall, followed by the J48 DT classifier with 96%. It was found that medical students are affected by anxiety and depression marginally more when compared with engineering students.
Research limitations/implications
The entire work is dependent on the social media-displayed online questionnaire, and the participants were not met in person. This indicates that the response rate could not be evaluated appropriately. Due to the medical restrictions imposed by COVID-19, which remain in effect in 2022, this is the only method found to collect primary data from college students. Additionally, students self-selected themselves to participate in this survey, which raises the possibility of selection bias.
Practical implications
The responses acquired through social media networks are analysed using ML algorithms. This will be a big support for understanding the mental issues of the students due to COVID-19 and can taking appropriate actions to rectify them. This will improve the quality of the learning process in higher education in Oman.
Social implications
Furthermore, this study aims to provide recommendations for mental health screening as a regular practice in educational institutions to identify undetected students.
Originality/value
Comparing the mental health issues of two professional course students is the novelty of this work. This is needed because both studies require practical learning, long hours of work, etc.

Abstract
Purpose
The purpose of this paper is to develop and validate an instrument intended to measure servant leadership behavior in the Chinese hospitality industry.
Design/methodology/approach
After reviewing the literature, a scale of nine dimensions with 81 items was generated and then subjected to exploratory factor analysis (EFA) using a sample of 600 participants from a polytechnic college and hospitality industry, resulting in 6-factor-33-item solution. The derived measure was then shortened to 24 items by using item response theory (IRT). Drawing on the data from 440 respondents in the hospitality industry, this 6-factor-24 item measure was subsequently validated with confirmatory factor analysis (CFA) and the test of construct validity.
Findings
Difference in factors has been found between this instrument and western-developed scales. This study resulted in 6-dimension-24-items scale. These dimensions were named integrity, self-sacrifice, building community, empowering people, emotional healing and visioning. This servant leadership scale was demonstrated to have good internal consistency reliability and strong construct validity.
Originality/value
This is the first study that used IRT as a statistic tool to shorten a servant leadership scale and also this study provided additional support to cultural psychology theory.
