Abstract

Purpose

The purpose of this paper is to establish a dynamic model considering the actual operating conditions of the train and to study the dynamic performance and vibration characteristics of axle box bearings under different operating conditions.

Design/methodology/approach

In this paper, based on the internal contact characteristics of double-row tapered roller bearings, a dynamic model considering the actual operating conditions of the train is established. The correctness of the model is verified by the vibration test of the bearing. Comparative analysis was conducted on the effects of axial force, radial force and rotational speed on the angular velocity of the cage, slip rate and vibration acceleration level of the inner ring.

Findings

As the force increases, the slip rate of the cages on both sides decreases, and the vibration acceleration level of the inner ring increases. With the increase of rotational speed, the cage slip rate of the axle box bearing increases and the vibration acceleration level of the inner ring increases.

Originality/value

A dynamic model is established considering the actual operating conditions, and the dynamic performance and vibration characteristics of the axle box bearing under different operating conditions are analyzed by numerical method. The research content can provide reference for the parameter design of high-speed railway bearings.

Abstract

Purpose

The purpose of this paper is to establish a dynamic analysis model of composite cylindrical roller bearings, investigate the effects of different working conditions on the kinematic characteristics of composite bearings and compare the differences between them and solid roller bearings.

Design/methodology/approach

This paper establishes a dynamic analysis model for composite cylindrical roller bearings and proves the correctness of the established model by establishing dynamic vibration experiments and contact theory for composite roller bearings. Comparative analysis was conducted on the effects of coupling changes in rotational speed, load, number of rollers and filling ratio on parameters such as bearing static stiffness, contact stress and vibration acceleration.

Findings

The composite roller can enhance the bearing’s operational stability and minimize contact stress, but that a higher filling ratio is going to increase the bearing’s stiffness. The acceleration degree of bearing vibration, the load on the outer raceway nodes and the bearing stability all decrease as inner ring speed rises.

Originality/value

A dynamic calculation model of composite cylindrical roller bearings is established, and the influence of multiparameter coupling changes on bearing vibration and contact is studied, which lays a foundation for the structural improvement of the bearings.

Abstract

Purpose

The purpose of this paper is to delineate the evolution of agricultural science and technology (S&T) in China in the last three decades as it has been one of the major factors, besides others, in ensuring comfortable levels of global food security. In doing so, it focuses on policy and progress, which have provided the right ambience for Chinese agricultural science and technology to evolve into an effective instrument of development.

Design/methodology/approach

The study employs institutional approach to government, scientists and farmers, who have been contributing to the growth of Chinese agricultural technology in two distinct ways. While the government has been playing a critical role in evolving a comprehensive agricultural S&T policy, scientists and farmers have been contributing to the progress of agricultural growth through research and application of various agricultural technologies.

Findings

Agricultural S&T in China has increasingly been growing into a potent force in facilitating comfortable levels of food security but with serious implications on the environment. Of the three players who have been instrumental in this process, the Chinese Government and the scientists are well prepared for WTO and globalization vis‐à‐vis agricultural technology, but the farmers are not well positioned.

Originality/value

Agricultural S&T development in China is critically important not only for Chinese food security but also for the larger global food and human security, as the two are inextricably connected. While most studies focus on various dimensions of agricultural technology, this study focuses on government, scientists and involved farmers, whose role is central to this process, and who are forced to rethink and reposition themselves in the development and use of agricultural S&T in China.

Abstract

Purpose

Drawing upon the social identity theory, the authors argue that professionals' career identities have a positive indirect effect on identification with on-demand organizations through career networking behavior. In addition, the strength of these beneficial effects was also bound by extraversion and collectivism.

Design/methodology/approach

The hypothesized moderated mediation model was tested by multisource and time-lagged data about 242 Chinese accountants engaging in on-demand work.

Findings

The results demonstrated that professionals with a career identity tend to engage in career networking behaviors and identify themselves with a client company. In addition, extraverted professionals were more likely to engage in career networking behaviors, and collectivist professionals were more likely to identify with their on-demand organizations.

Practical implications

This research provides important guidelines on how managers in on-demand organizations leverage gig workers' career identities to establish deep relationships with them.

Originality/value

The authors expanded the traditional framework of identification in the setting of nontraditional work arrangements by establishing a link between career identity and organizational identification for on-demand professionals.

Abstract

Purpose

Frontline employees’ proactive behaviors (i.e. job crafting) are critical to satisfying customers’ idiosyncratic needs. If the supervisors practice job crafting, their subordinates are more likely to mimic such behaviors. However, there has been limited research on how leaders’ job crafting can influence subordinates’ job crafting. This study aims to examine the cross-level mechanisms (i.e. trickle-down effects) of supervisors’ job crafting on the subordinates’ attitudes and performance. Specifically, such trickle-down effects can be explained via two cross-level mechanisms of the supervisors’ job crafting on the subordinates’ work engagement and performance: social learning mechanism and job demands-resources mechanism.

Design/methodology/approach

A three-wave cross-lagged study was conducted in two-week intervals. The valid responses from 67 supervisors and their 201 subordinates were collected. The data set was analyzed using multilevel Structural Equation Modeling.

Findings

The results demonstrated that the social learning and job demands-resources mechanisms are not independent. The supervisor’s job crafting improves employment relationships, subsequently encourages subordinates’ job crafting and ultimately enhances work engagement and work performance.

Practical implications

The findings suggested that hospitality organizations should encourage job crafting among supervisors and managers. A proactive hotel manager can establish strong employment relationships, motivate subordinates to work proactively and obtain positive work outcomes.

Originality/value

The findings enrich the knowledge about the trickle-down effects of supervisors on subordinates in terms of job-crafting behaviors. In particular, this study found a new theoretical perspective that the job demands-resources and social learning mechanisms may not be independent, and the subordinates’ perception of the employment relationship plays a critical role.

Abstract

Purpose

This paper aims to examine the impacts of transformational leadership and employee proactive personality on service performance, the mediation role of organizational embeddedness and the synergies of transformational leadership and proactive personality within the proposed framework.

Design/methodology/approach

Data was collected following a time-lagged research approach. The study sample included 218 frontline employees and their supervisors from ten carefully selected five-star hotels in China. Structural equation modeling was employed for the data analysis.

Findings

Transformational leadership and proactive personality had positive effects on task performance and contextual performance via organizational embeddedness. The interactive influences of transformational leadership and proactive personality on task performance and contextual performance were found significant and negative.

Originality/value

Transformational leaders and proactive employees have been shown to exert a strong influence on excellent service performance, with organizational embeddedness playing a critical role.

Abstract

The overall goal of this chapter is twofold. First, the authors aim to identify indigenous phenomena that influence employee turnover and retention in the Chinese context. Second, the authors link these phenomena to the contextualization of job embeddedness theory. To achieve the goal, the authors begin by introducing three macro-level forces (i.e., political, economic, and cultural forces) in China that help scholars analyze contextual issues in turnover studies. The authors then provide findings in the literature research on employee retention studies published in Chinese academic journals. Next, the authors discuss six indigenous phenomena (i.e., hukou, community in China, migrant workers, state-owned companies, family benefit prioritization, and guanxi) under the three macro-level forces and offer exploratory propositions illustrating how these phenomena contribute to understanding employee retention in China. Finally, the authors offer suggestions on how contextualized turnover studies shall be conducted in China.

Abstract

Purpose

Using the theoretical lens of sensemaking, this paper aims to investigate the relationship between on-the-job shocks, as experienced by the employees and intention to stay (IS) by shedding light on the mediating role of organizational embeddedness (OE) and the moderating role of commitment human resource practices (CHRP).

Design/methodology/approach

The study used a time-lagged research design, collecting data from 304 employees from 48 teams in China to conduct multilevel structural equation modeling to test hypotheses.

Findings

This study found that employees who suffer on-the-job shocks tend to decrease their IS in organizations via OE. However, CHRP did not bound the main effect of on-the-job shocks on OE.

Practical implications

Given the increasingly dynamic business environment, employees constantly encounter shocks in the workplace. Organizations or leaders should be aware of the on-the-job shocks in harming employee retention.

Originality/value

The research highlights workplace events’ significance in investigating employees’ retention and specifically offers glimpses into the mechanisms by which on-the-job shocks manifest themselves in employees’ IS.

Abstract

Purpose

Mentoring was considered as an efficient way to facilitate staff attachment with hotels. Such a strong attachment has been demonstrated to reduce employees’ intention to quit. This study aims to investigate the mediating roles of organizational and occupational embeddedness in the relationships between mentoring functions and turnover intention.

Design/methodology/approach

The responses were collected from a sample of 354 employees in four hotels group across three Chinese provinces. A structural equation model (SEM) was applied to test the model and mediating roles of organizational and occupational embeddedness.

Findings

The results of SEM suggest that both organizational and occupational embeddedness mediated the relationships between mentoring functions (career and psychosocial support) and turnover intention. Specifically, employees who are able to receive successful mentoring can easily embed in their organization and occupation. Thus, these employees are reluctant to leave.

Research limitations/implications

Although this study reveals the important role of mediation, it has several limitations. First, the data drawn from Hebei, Beijing and Zhejiang provinces may lack geography representativeness. Second, this paper neglects potential moderating role of certain personal or context factors. Third, the time lag between the three data collections are not the same.

Practical implications

Managers should retain proper employees by introducing mentoring programs. Furthermore, to increase organizational and occupational embeddedness, managers should also consider the person-organization/occupation attachments of this industry.

Originality/value

This study tests organizational and occupational embeddedness simultaneously as mediators between mentoring and turnover intention through data obtained from the Chinese hotels.

Abstract

Purpose

Civil service workers are valuable resources for any nation and play a crucial role in driving their country’s economic development. Per the supervisor, this research examines the impact of mindfulness, proactive personality, and career competencies on employee job performance. The study also analyzes the effects of career adaptability and identity on this aspect.

Design/methodology/approach

To test the model of this study, questionnaires were administered to a sample of 500 civil service employees whose career-based knowledge and skills were measured in various cities in the province of Punjab, Pakistan.

Findings

Mindfulness and career competencies significantly impact supervisor-rated task performance, whereas a proactive personality does not substantially relate to supervisor-rated task performance. Research indicated that the two hypotheses about mediation were accepted. However, career adaptability does not play a significant role in the link between mindfulness and how well a supervisor rates task performance. Regarding moderation, career identity did not significantly moderate the relation between proactive personality and supervisor-rated task performance. However, the other two moderate hypotheses have been proven to be significant.

Research limitations/implications

The findings offer compelling support for career construction theory (CCT) in this study area by analyzing the connections related to career adaptability and identity within the framework. In the future, researchers can build on this model by adding theories like conservation of resources (COR), looking into possible moderators that might change specific pathways in this network of relationships and using longitudinal designs to find stronger causal relationships.

Originality/value

Considering the evolving workplace due to the COVID-19 pandemic, the study offers fresh perspectives on the post-COVID situation, understanding and integrating various variables. For future studies, more variables can be explored in this model with the expansion of sample size and change of context.
