While many studies have focused on the effectiveness of service recovery after encountering service failure, few have considered for pre-recovery opportunities. Drawing on service guarantee research and the inoculation theory, this study examines the effect of pre-recovery strategy on customer’s satisfaction when faced with possible service failure. This study takes into consideration the uncertainty of service failure, including specific or unpredicted failures.

Three experimental studies were conducted to examine our research hypotheses, which include a total of 1203 subjects recruited from online and offline platforms.

The findings reveal that service guarantees and inoculation messages both effectively mitigate the negative consequences of a service failure. Specifically, the pre-recovery strategy is particularly effective for specific service failures. In addition, we thoroughly examined the mediating role of customer attribution.

This research significantly contributes to the existing literature on service research by delving into the potential positive impact of proactive measures undertaken by service enterprises. Furthermore, the findings of this research offer valuable insights for practitioners.

The purpose of this study is to examine the effects of executives’ overseas education and work experience on enterprise digital as executives’ overseas background is critical to the development of enterprises. It also explored the mediating role of enterprise digital transformation on the relationship between executives’ overseas background and enterprise growth.

Chinese A-share companies listed on the Shanghai and Shenzhen Stock Exchanges for the period 2018–2020 were analyzed using regression analysis and bootstrapping to verify hypothesized relationships.

Executives’ overseas study and work experience both enhanced enterprise digital transformation significantly, thus improving enterprise growth. The level of employee education moderated the mediating role proposed in the theoretical model. Moreover, the promoting effect of executives’ overseas background on enterprise digital transformation was more significant for non-state-owned enterprises and those in eastern China.

The findings provide reference for the formulation and optimization of companies’ human resource structure and have implications on the improvement of enterprise digital transformation and enterprise growth.

This study explored the factors influencing enterprise digital transformation at the microlevel of corporate human capital, thereby providing microlevel empirical evidence for research on the factors influencing enterprise digital transformation. Its findings shed light on the mechanism and context under which executives with overseas backgrounds may enhance enterprise digital transformation and growth.

The content of pore-foaming agent directly affects pore characteristics and oil-absorption properties of polyimide (PI) porous materials, which further influence the tribological performance of PI pore material. This research paper aims to discuss these issues.

Thermal vacuum molding technology was adopted to prepare PI porous material with different structures by changing the content of the pore-forming agent to control pore size and porosity of the PI material. PI oil-bearing materials were obtained by vacuum oil immersion. The tribological experiments of PI oil-bearing materials were conducted on the CETR friction and wear testing machine.

The study results showed that PI porous material with a specific structure can be obtained by controlling the content of a pore-forming agent. In a certain range, with the increase in the content of the pore-forming agent, the average pore size and porosity increased, also the oil content increased, which means that the friction coefficient and wear rate decreased to a very large extent, and antifriction and wear resistant properties of the PI porous materials greatly improved. When the content of the pore-forming agent exceeds 8 per cent, the wear rate and friction coefficient of the PI porous materials began to increase.

Because the complexity of the tribological system consists of lubricating oil, porous material and friction pair, the physical understanding of the mechanism of this process remains limited. Therefore, the present research was undertaken to identify the phenomena involved, which will provide practical guidance for the tribological application in the field of bearing parts.

This study aims to research the erosion wear characteristics and sealing performance of V-regulating ball valve in coal chemical process pipelines, which provides a theoretical reference for improving its antiwear and sealing performance.

Taking the V-regulating ball valve as the research object, based on the computational fluid dynamics and the theory of erosion wear, the authors studied its erosion characteristics under different medium parameters and analyzed the sealing performance under the heat-fluid–solid coupling working condition.

The erosion wear mechanism of the valve sealing surface is the simultaneous action of cutting and deformation. When the medium flow velocity, particle mass flow rate and particle size increase, the maximum erosion rate and average erosion rate in the V-regulating valve increase. The inner diameter Mises contact stress of the sealing surface is symmetrically distributed in a “wing shape,” and the contact stress of the outer diameter is distributed in a “butterfly shape.” Due to the superposition of thermal stress and pressure stress in the contact transition zone to produce a significant stress concentration.

The findings will provide a theoretical basis for improving the erosion resistance and sealing performance of V-regulating ball valve in coal chemical industry.

V-type regulating ball valve is widely favored by coal chemical enterprises and petrochemical enterprises because of its wide adjustment ratio and good erosion resistance.

The V-regulating ball valve wear mechanism for cutting and deformation simultaneously, and its wear rate is positively correlated with the medium flow rate, particle mass flow rate and particle size. After the valve is opened, there is a significant stress concentration occurs in the contact transition zone due to the superposition of thermal stress and compressive stress. The findings will provide a theoretical basis for improving the erosion resistance and sealing performance of V-regulating ball valve in coal chemical industry.

The purpose of this study is to investigate the sealing performance of different deep groove mechanical seals by considering the changing law of dynamic pressure effect and temperature gradient caused by high speed and high pressure.

A thermohydrodynamic lubrication model (THD) of the mechanical seal was constructed and solved using the commercial software FLUENT. The pressure and temperature distributions of the fluid under different groove types, as well as the sealing performance under different pressures, rotational speeds and sealing gaps, are obtained.

The annular groove (AG) can effectively reduce the temperature, and the T-type spiral groove (STG) can effectively inhibit the leakage. The increase of pressure and rotational speed leads to the enhancement of dynamic pressure effect and the increase of leakage, while the sealing gap increases and the leakage increases while taking away more heat. The choice of groove type is very important to the impact of sealing performance.

In consideration of the beneficial effect of deep grooves on cooling performance, the viscous temperature equation and the impact of the thermodynamic lubrication model are evaluated in conjunction with the sealing performance of four distinct groove types. This approach provides a theoretical basis for the optimal design of mechanical seals.

This paper aims to explore why some Chinese subordinates will engage in building guanxi with their supervisor while others will not. The authors conceptualize subordinates’ initiative behaviors which aim at building up or improving guanxi with their supervisors through social interactions as supervisor–subordinate guanxi (SSG)-building behaviors. Guided by the theory of planned behavior (TPB), this study examines how three psychological antecedents (guanxi orientation as attitude, individual perception of group-level guanxi practice as subjective norm and person–supervisor [P-S] fit perception as perceived control) independently and interactively predict subordinates’ SSG-building behaviors.

The authors used a sample of 162 supervisor–subordinate dyads from four enterprises located in Southwest China.

Results indicated that P-S fit perception is most strongly related to subordinates’ SSG-building behaviors, followed by guanxi orientation and individual perception of group-level guanxi practice perception. Guanxi orientation is also found to strengthen the positive effect of P-S fit perception on subordinates’ SSG-building behaviors.

The authors’ findings shed light on the psychological mechanisms of Chinese subordinates’ behaviors to build up or improve guanxi with their supervisors, and advance the current understanding of SSG development from a planned behavioral perspective.

This paper aims to inquire and argue for a renovated model of Confucian political leadership as a way of political governance rooted in a philosophy of humanity and its potential for development.

The paper is primarily critical and constructive through philosophical analysis and synthesis of ideas and insights into nature of man and political leadership in light of Confucian texts and practices.

Based on reflection and analysis, the classical model of political leadership is shown to consist of core values of virtues and visions in classical Confucianism. By conceptual reconstruction a new Confucian model is formulated in such a way in which ethics of utilities and ethics of justice and righteousness are incorporated. The author further shows how it can be realized in different functions of modernized political and economic leadership. The author finds that this move resulted in achieving an essential transformation toward a more realistic application and practice in a global world.

In so far as the new model deals with a process of normative harmonization in which it can be further enhanced by comprehensive considerations of intrinsic human values and future development of humanity as a whole, this model provides a practical method for meeting the urgent needs on different levels of leadership and management for creative and world‐oriented attitude‐building, policy‐making and strategic seminar‐course designing for graduate and executive training in contemporary business schools.

The author has innovatively constructed the new Confucian model and show how political leadership in this model has the capability and ability to persevere in seeking harmony and harmonization among traditions and nations in the global world. The author has also explained how and why morality when properly supported can be a global leading power for bringing harmony and harmonization to the world. The author has formed a new concept of political leadership force and named it the moral power in addition to but not separated in its persuasion from hard power, soft power and smart power of Joseph Nye. The author's formulation and argument for the new model with its moral power constitute a highly significant contribution to the understanding of Confucian political leadership in contemporary global contexts.
