Abstract
Purpose
The purpose of this paper is to construct an event-triggered finite-time fault-tolerant formation tracking controller, which can achieve a time-varying formation control for multiple unmanned aerial vehicles (UAVs) during actuator failures and external perturbations.
Design/methodology/approach
First, this study developed the formation tracking protocol for each follower using UAV formation members, defining the tracking inaccuracy of the UAV followers’ location. Subsequently, this study designed the multilayer event-triggered controller based on the backstepping method framework within finite time. Then, considering the actuator failures, and added self-adaptive thought for fault-tolerant control within finite time, the event-triggered closed-loop system is subsequently shown to be a finite-time stable system. Furthermore, the Zeno behavior is analyzed to prevent infinite triggering instances within a finite time. Finally, simulations are conducted with external disturbances and actuator failure conditions to demonstrate formation tracking controller performance.
Findings
It achieves improved performance in the presence of external disturbances and system failures. Combining limited-time adaptive control and event triggering improves system stability, increase robustness to disturbances and calculation efficiency. In addition, the designed formation tracking controller can effectively control the time-varying formation of the leader and followers to complete the task, and by adding a fixed-time observer, it can effectively compensate for external disturbances and improve formation control accuracy.
Originality/value
A formation-following controller is designed, which can handle both external disturbances and internal actuator failures during formation flight, and the proposed method can be applied to a variety of formation control scenarios and does not rely on a specific type of UAV or communication network.

Abstract
Purpose
This study aims to build a framework of the influencing factors of construction workers' career promotion and identifies the critical determinants so as to propose suggestions for the government and enterprises to offer construction workers a path for career promotion.
Design/methodology/approach
In line with the theory of human resources, such as Herzberg's two-factor theory, this study constructs a theoretical framework that affects the career promotion of construction workers. Using evidence from Guangzhou city, valid data provided by 464 workers from 50 sites were collected by a questionnaire survey, and the significance test on the influencing factors of construction workers' career promotion was taken by binary logistic regression.
Findings
The overall career development of construction workers in Guangzhou is worrying. The binary logistic regression indicates that age, working years, type of work, career development awareness, legal awareness, professional mentality, vocational psychological training and career development path are critical factors that affect construction workers' career promotion.
Originality/value
This study for the first time explores the career promotion of frontline construction workers. Specifically, it identifies the critical factors that affect the career promotion of workers and thus lays a foundation for further research and the promotion and continuous and healthy development of the construction industry. Thus, this study is original and has theoretical and practical significance.

Abstract
Purpose
China is not only the biggest mutton consumer, but also the top mutton importer in the world. China’s urban households are becoming the key driving force behind a surge in mutton consumption. Therefore, the purpose of this paper is to investigate the determinants of mutton demand in urban China.
Design/methodology/approach
Based on a sample of 32,910 urban households across six provinces and autonomous regions, an inverse hyperbolic sine (IHS) double-hurdle model is estimated, by maximum likelihood estimation, to reveal the determinants of mutton consumption-at-home.
Findings
The empirical results indicate that, first, household income has a positive effect on mutton consumption, and higher income households have a higher income elasticity; second, wet weather increases probability, but reduces conditional level and unconditional level; finally, minority group households consume more mutton than Han group households.
Practical implications
It is necessary for policymakers to develop a long-term outlook in relation to the increase of China’s mutton appetite and to shift from a domestic perspective to a global one and develop diversified import strategies. Furthermore, policymakers require to make a practicable emergency preplan for tackling short-term agglomeration of demand for mutton, attributed to festivals, and religious events of a minority ethnic group.
Originality/value
This is a major work based on a large sample of 32,910 urban households conducted by the National Bureau of Statistics of China. This paper uses an IHS double-hurdle model to quantify the determinants of mutton consumption; it sheds light on the climatic, regional, and ethnic characteristics of mutton consumption in urban China.

Abstract
Purpose
Football stadiums, traditionally linked to local landmarks, now see a shift as corporate brands engage in naming rights through sponsorship. However, limited scholarly attention has focused on the perception of stadium toponyms. This research initiative aims to gauge attention garnered by football stadiums in Europe and China based on various naming rights options.
Design/methodology/approach
Commencing with a well-known European stadium: Allianz Arena (Munich) and new constructed stadium in China, the original naming rights have been proffered as stimuli, in comparison with two major technology brands as well as Coca-Cola, the historical sponsor of sport mega-events. A sample of 100 participants was analyzed using the eye-tracking technique to compare the perceptions of European and Chinese youth.
Findings
The conclusion drawn from the study is that for stadiums with a history of sponsorship, unedited versions of the pictures attract the most attention. Compared with technology brand, Coca-cola is the brand with the greatest ability to attract the attention of young people in both historical stadiums or new constructed stadium, acting as an impulse to the activation of the naming rights strategy due to its historical character as a sponsor of mega sporting events.
Originality/value
The research makes dual contributions, both theoretically and practically. It enhances comprehension of audience visual attention patterns in the context of football stadium naming rights sponsorship, employing cognitive attention theory to substantiate empirical evidence. Furthermore, it advances the existing literature on football stadium naming rights research. Additionally, it proposes an optimization tool to assess the effectiveness of naming rights sponsorships, offering valuable insights for companies and brands seeking to enhance their marketing strategies.

Abstract
Purpose
The purpose of this paper is to trace back the roots of US-driven “Human Resource Management” (HRM) school of thought which now become widely institutionalized in China, up to the present day.
Design/methodology/approach
It looks at the diffusion of management knowledge over the period to Chinese business, which involved in turn scientific management (SM), human relations (HR) and HRM, respectively, from the interwar years onwards, by using a bibliometric analysis of Chinese language sources, searching a number of databases now available.
Findings
The authors scanned the international, as well as Chinese, literature to support a conjecture of a HR route towards China and how it morphed into HRM and went on to conclude that there was by the end of the year 2015 still a significant output of academic publications with references to both HR and HRM, respectively, but that we must be cautious in asserting a firm conclusion.
Originality/value
This paper traces back the roots of Chinese HRM back to the US-driven HR school of thought.

Abstract
Purpose
To understand how retail companies are using TikTok, a short-form video social media platform, this study investigates the use of relationship cultivation strategies and message appeals in TikTok videos posted by the top 100 retail companies. The study also examines the extent to which these strategies influence public engagement on TikTok.
Design/methodology/approach
A quantitative content analysis was conducted to analyze the use of relationship cultivation strategies and message appeals by the top 100 retail companies on TikTok. The study also applied negative binomial regression to assess the impact of these strategies on public engagement.
Findings
The findings show that the positivity strategy was the most frequently used relationship cultivation strategy, followed by networking and assurance. The analysis also revealed that about half of the videos employed at least one message appeal. The use of relationship cultivation strategies and message appeals had significant effects on public engagement.
Originality/value
This study is one of the first to examine the role of relationship cultivation strategies and message appeals in enhancing social media engagement for companies on TikTok.

Abstract
Purpose
This study aims to investigate the sealing performance of a novel ribbed oil-slinging ring composite seal (ROSRCS) for the axle end of train gearboxes. The ROSRCS design incorporates added ribs and an inclined outer edge to enhance the sealing mechanism and reduce oil leakage.
Design/methodology/approach
Computational fluid dynamics simulations were used to analyze the leakage characteristics of ROSRCS under varying angles, outer edge inclinations and rib numbers and heights. The sealing performance was compared to a traditional oil-slinging ring composite seal (OSRCS). Key parameters such as oil leakage rate, turbulence dissipation intensity and jet strength were evaluated.
Findings
Results indicate that ROSRCS reduces the oil leakage rate by 5.7% compared to OSRCS. At a slinger ring inclination of 35°, the turbulence dissipation center in the ROSRCS flow field shifts toward the inlet, increasing the maximum turbulence dissipation intensity by 22.56%. A proper outer edge inclination enhances jet intensity, strengthening turbulence dissipation by up to 9.21%. While adding ribs may generate negative pressure zones, strategic rib configurations improve axle-end sealing performance by modifying the number, position and intensity of vortices.
Originality/value
This research presents a refined composite seal design that enhances the sealing efficiency of train gearbox axle ends, demonstrating improved oil retention through innovative geometric modifications. The findings contribute to the development of more efficient sealing technologies in high-speed train applications.

Abstract
Purpose
The purpose of this paper is to combine triboelectric nanogeneration technology with ball bearing structure to achieve energy collection and fault monitoring.
Design/methodology/approach
In this paper, according to the rotation mode of ball bearings, the freestanding mode of triboelectric nanogeneration is selected to design and manufacture a novel triboelectric nanogeneration device Rolling Ball Triboelectric Nanogenerator (RB-TENG) which combines rotary energy collection with ball bearing fault self-sensing.
Findings
The 10,000s continuous operation experiment of the RB-TENG is carried out to verify its robustness. The accurate feedback relationship between the RB-TENG and rotation velocity can be demonstrated by the fitting comparison between the theoretical and experimental electrical signal periods at a certain time. By comparing the output electrical signals of the normal RB-TENG and the rotor spalling RB-TENG and polytetrafluoroethylene (PTFE) balls with different degrees of wear at 500 r/min, it can be concluded that the RB-TENG has an ideal monitoring effect on the radial clearance distance of bearings. The spalling fault test of the RB-TENG stator inner ring and rotor outer ring is carried out.
Originality/value
Through coupling experiments of rotor spalling fault of the RB-TENG and PTFE balls fault with different degrees of wear, it can be seen that when rotor spalling fault occurs, balls wear has a greater impact on the normal operation of the RB-TENG, and it is easier to identify. The fault self-sensing ability of the RB-TENG can be obtained, which is expected to provide an effective scheme for monitoring the radial wear clearance distance of ball bearings.

Abstract
Purpose
From a psychosocial perspective, this study aims to understand the impact of psychosocial safety climate (PSC) on the intent to stay of construction workers and provides practical recommendations for construction enterprises to retain construction workers.
Design/methodology/approach
This study proposes the conceptual framework explained by the conservation of resources (COR) theory and develops a mediation model of “PSC – job satisfaction – intent to stay” within the framework supported by the stimulus–organism–response (SOR) model. Then, a questionnaire survey of 489 construction workers in Guangzhou was conducted and structural equation modeling (SEM) analysis was performed on the data collected.
Findings
Results show that PSC has a significant and positive effect on job satisfaction and intent to stay. In addition, job satisfaction partially mediates the effect of PSC on intent to stay. Hence, the theoretical model of “PSC – job satisfaction – intent to stay” has been empirically tested and supported.
Originality/value
This study is the first to investigate the effect of PSC on intent to stay and enriches the research on the retention of construction workers. The COR theory explains well the mechanism of PSC influence on intent to stay, thus expanding its application to the construction field. Moreover, this study provides practical recommendations for construction enterprises to retain workers so as to build a stable and productive workforce.
