Abstract
Purpose
Random point-contact between the space bearing retainer and the rolling elements may cause wear of the space bearing retainer. The paper aims to clarify the friction and wear behaviors of polyimide bearing retainer under point-contact condition.
Design/methodology/approach
Space bearing retainers were cut into flat specimens and the tribological behaviors of the specimens were studied under point-contact condition using a friction and wear testing machine. Different sliding velocities and normal loads were used to simulate the running state of space bearing retainer. The wear behaviors of the space bearing retainer were analyzed by SEM and white light interferometer.
Findings
The friction coefficient of the polyimide composites decreased with increase in sliding velocity from 1 to 5 mm/s. Moreover, with increase in sliding velocity and normal load, the wear rate of the polyimide composites decreased and increased, respectively. Moreover, the wear behaviors of the polyimide composites were mainly determined by the combined actions of ploughing friction and adhesive friction. The lubricating properties of transfer film and wear debris were limited under point-contact condition.
Practical implications
The paper includes implications for the understanding of the wear mechanism of the polyimide composites space bearing retainer under point-contact condition and then to optimize space bearing retainer materials further.
Originality/value
Under point-contact condition, wear debris can hardly participate in the friction process because of limited contact area. Consequently, the wear debris has limited impact on the wear process to decrease the friction and wear.

Abstract
Purpose
A plethora of organizational studies have found employee narcissism to be an unfavorable trait that impedes job functioning. Yet, the elevated confidence and self-assuredness associated with the narcissistic personality can also drive individuals to show initiative behavior. This paper aims to investigate how and when employees with narcissistic personalities can potentially contribute positively to effective functioning.
Design/methodology/approach
Data were collected from 91 supervisors and 273 subordinates in a corporate setting in central China. To account for the nesting effects, multilevel path analysis was conducted to test the hypotheses.
Findings
Employee narcissism is positively related to psychological ownership, which in turn is positively related to initiative behavior in the workplace. Furthermore, job meaningfulness moderates the indirect effect of employee narcissism on initiative behavior through psychological ownership. Specifically, the indirect effect is more salient when the employee perceives higher, rather than lower, job meaningfulness.
Originality/value
This study examines how employees with narcissistic personalities can show initiative at work. Specifically, this research uncovers the underlying psychological mechanism as well as the boundary condition that facilitate this process. This study affirms the importance of self-determination for narcissistic employees and sheds light on how these employees can potentially contribute positively to effective functioning. Insights for theory, practice and future research are also discussed.

Abstract
Purpose
This paper aims to provide theoretical analysis and empirical study on the relationship between training and organizational commitment; analyze the mediating role of employability and the moderating role of expectation value in their relationship; and draw from both of these to suggest practical implications to organizations aiming to effectively train and retain employees, and for employees themselves.
Design/methodology/approach
First, the paper reviews the literature regarding training, employability, organizational commitment and expectation value. Second, it develops a theoretical model linking training, employability, organizational commitment and expectation value, and proposes a series of research hypotheses. Third, drawing on samples of 405 Chinese employees, it tests hypotheses based on a series of measurement and statistical analyses. Last, it discusses the analysis results and puts forward related suggestions for management practice.
Findings
The paper tests and verifies the applicability of Western training and employability scales in China from a self-perception perspective. Training is positively related to organizational commitment and employability. Further, employability partly mediates the relationship between training and organizational commitment, and expectation value moderates the relationship between employability and organizational commitment.
Research limitations/implications
First, the cross-sectional design prevents the making of causal statements. Future research should adopt an experimental (quasi experimental) research method or longitudinal research to study the casual relationship between variables. Second, data are from employees’ self-report, giving rise to concern about possible common source bias. Future research should allow supervisors to rate employees’ employability or provide evaluation of employees’ expectation value to collect multi-source data.
Originality/value
The paper first introduces Western scales of training and employability into a Chinese context, and then tests and verifies the two scales' applicability in China. To explain the action mechanism of training to the employee – organizational commitment in a boundaryless career, the paper constructs a moderate mediation model to test the direct effect of training on organizational commitment, the mediating effect of employability and the moderating effect of expectation value. This study complements past research by investigating both the mediating and moderating mechanisms in training organizational commitment.

Abstract
From the sixteenth to eighteenth century, China underwent a commercial revolution similar to the one in contemporaneous Europe. The rise of market did foster the rise of a nascent bourgeois and the concomitant rise of a liberal, populist version of Confucianism, which advocated a more decentralized and less authoritarian political system in the last few decades of the Ming dynasty (1368–1644). But after the collapse of the Ming Empire and the establishment of the Qing Empire (1644–1911) by the Manchu conquerors, the new rulers designated the late-Ming liberal ideologies as heretics, and they resurrected the most conservative form of Confucianism as the political orthodoxy. Under the principle of filial piety given by this orthodoxy, the whole empire was imagined as a fictitious family with the emperor as the grand patriarch and the civil bureaucrats and subjects as children or grandchildren. Under the highly centralized administrative and communicative apparatus of the Qing state, this ideology of the fictitious patrimonial state penetrated into the lowest level of the society. The subsequent paternalist, authoritarian, and moralizing politics of the Qing state contributed to China’s nontransition to capitalism despite its advanced market economy, and helped explain the peculiar form and trajectory of China’s popular contention in the eighteenth century. I also argue that this tradition of fictitious patrimonial politics continued to shape the state-making processes in twentieth-century China and beyond.

Abstract
Purpose:
The purpose of this paper is to examine how Si-shu, a traditional form of local, private education grounded in classical instruction, responded to the rapid modernization of education during the late Qing dynasty and early Republic of China and to explain why these schools, once extraordinarily adaptable, finally disappeared.
Design/methodology/approach:
The authors have examined both primary and secondary sources, including government reports, education yearbooks, professional annals, public archives, and published research to analyze the social, political and institutional changes that reshaped Si-shu in the context of China's late-19th- and early-20th-century educational modernization.
Findings:
Si-shu went through four stages of institutional change during the last century. First, they faced increased competition from new-style (westernized) schools during the late Qing dynasty. Second, they engaged in a process of intense self-reform, particularly after the Xinhai Revolution of 1911. Third, they were marginalized by the new educational systems of the Republic of China, especially the Renxu School System of 1922 and the Wuchen School System of 1928. Finally, after the foundation of the People's Republic of China in 1949, they were considered remnants of feudal culture and forcibly replaced by modern schools.
Originality/value:
This paper brings hitherto unexplored Chinese sources to an English-speaking audience in an effort to shed new light on the history of traditional Chinese education. The fate of Si-shu was part of the larger modernization of Chinese education – a development that had both advantages and disadvantages.

Abstract
Purpose
The purpose of this paper is to provide a micro historical account of the work of a key Chinese educational reformer, Tao Xingzhi (1891–1946), who transformed educational ideas from John Dewey to effect social and cultural change in 1920s–1940s China.
Design/methodology/approach
This paper examines English and Chinese language sources, including Tao’s poetry, to present a fresh analysis of Tao’s epistemological life history. It draws upon transnational historical approaches to chart the multidirectional circulation of progressive education philosophies around the globe. It also explores some conceptual dimensions of Chinese historical thinking and historiographical strategies.
Findings
Tao Xingzhi engaged in critical intercultural knowledge exchange in implementing educational reforms in China. He blended and critiqued Chinese and Deweyian educational philosophies to create unique educational reform, which involved reversing some of Dewey’s approaches as well as adapting others.
Originality/value
This paper foregrounds Tao Xingzhi’s agency in transforming some of Dewey’s ideas in the Chinese context and challenges studies that adopt an “impact-response” approach to Tao’s contribution, which suggest a one-way flow of knowledge from a “modern” West to a “traditional” China. It brings hitherto unexplored Chinese language sources to an English-speaking audience, particularly Tao’s poetry, to gain new historical insights into Tao’s educational reforms. It contributes to transnational understandings of the multidirectional flows of knowledge about Progressive educational philosophies around the world.

This paper aims to explore the impact of corporate social responsibility and hypocrisy on the relationship among psychological contract violation, trust and perceived betrayal.
Abstract
Purpose
This paper aims to explore the impact of corporate social responsibility and hypocrisy on the relationship among psychological contract violation, trust and perceived betrayal.
Design/methodology/approach
This study used purposive sampling and selected students in Taiwan as the research participants. The theory of psychological contract violation and consumer awareness process in violation hypocrisy on psychological contract violation were used to investigate the effect of its impact on trust and perceived betrayal. Then, the moderating effect of social responsibility and hypocritical on trust, and the mediating effect of trust between psychological contract violation and perceived betrayal were analyzed.
Findings
The results indicated that hypocrisy had a significant and negative impact on psychological contract violation toward trust; hypocrisy had a significantly positive impact on psychological contract violation toward perceived betrayal; trust had a significantly negative impact on perceived betrayal; perceived betrayal had a significantly positive impact on both direct and indirect revenges; trust had a mediating effect between hypocrisy toward psychological contract violation and perceived betrayal; and higher hypocrisy would produce a stronger effect through trust on the relationships between hypocrisy toward psychological contract violation and perceived betrayal.
Originality/value
Perception of consumers would differ whenever there were failures of service recovery occurred; especially, stronger betrayal feeling would be perceived with the companies who emphasized social responsibility and did not carry out what they should do. Research results could be references for companies whom advertising and praising social responsibility.

Abstract
Purpose
Confucian nurturing doctrine of xin (heart‐mind) comprehensively illustrates the importance of emerging state of feelings, which are the antecedents of organizational and individual behaviors. This introductory paper seeks to provide meaningful references for the management education and research trends like organizational justice and emotional intelligence.
Design/methodology/approach
Based on Confucian nurturing doctrine of xin (heart‐mind), this paper analyzes: the connotation of xin, qing (emotions/feelings) as the manifestation of xing (nature) by xin, and the cultivation of xin. Accordingly, the authors propose the holistic man model based on emotions.
Findings
The holistic man model based on emotions contains natural, social, moral, and transcendental dimensions. Self‐cultivation is significant for management practices and education.
Research limitations/implications
As a conceptual essay, the statements in the paper need further argument and exploration.
Practical implications
A referential hypothetical model of human nature based on Confucian nurturing doctrine of xin can make people have transcendent aspiration in their daily life and focus on the unity of individuals' natural feelings and moral cultivation. In this case, people can live an integrated, meaningful and healthy life based on their emerging state of emotions, which are the antecedents of the transactional, instrumental, and procedural regulations.
Originality/value
This paper contributes to the notions of the holistic man based on emotions and emerging state of emotions by referring to Confucian nurturing doctrine of xin (heart‐mind).

Abstract
Purpose
The purpose of this paper is to investigate the hydrodynamic performance of liquid film seals with oblique grooves (OGs) and spiral grooves (SGs), considering cavitation, compare and analyze the differences between them.
Design/methodology/approach
Considering cavitation effect, the incompressible steady-state Reynolds equation was solved to obtain the sealing performance parameters of the liquid film seal with oblique groove and spiral groove.
Findings
The hydrodynamic performance of oblique groove seal (OGS) and spiral groove seal (SGS) shows a similar trend with the change of operating parameters. When the groove angle is less than 20°, the load-carrying capacity of SGS is better than that of OGS, while when the groove angle continues to increase, the hydrodynamic performance of OGS is slightly better than that of SGS, and more suitable for use under small differential pressure and high speed.
Originality/value
The hydrodynamic characteristics of liquid film seals with oblique grooves and spiral grooves considering cavitation effect were studied, which provides a theoretical reference for the application of oblique groove seal.

Abstract
Purpose
Integrated project delivery (IPD) and building information modeling (BIM) has begun to be used in real estate development projects over the past decade to improve collaboration, communication and efficiency. However, the use of BIM and IPD in projects does not always imply that the information is well used and managed. This study aims to explain how information management should be carried out in BIM and IPD projects, what activities should be managed by the information manager and which stakeholder should play this role and why?
Design/methodology/approach
This study provides a framework on the subject by conducting a comprehensive systematic review in the field of real estate development, BIM, IPD and information management. In this context, the Web of Science and Scopus databases have been systematically reviewed, n = 45 out of a total of n = 1,356 articles and additionally, the BIM documents and standards prepared by public institutions and organizations and industry reports have been examined in detail.
Findings
The framework for information management roles was established by reviewing the literature. According to this framework, information management activities of information managers are listed in the table that covers all phases of real estate development. The owner should undertake this role as it is the entity that oversees the built asset from planning to the management of that facility.
Originality/value
In terms of acquiring information management roles, there is no research on BIM and IPD projects and who will take over this role. This study desired to close this gap in the literature.
