The purpose of this paper is to investigate the moderating effect of employee emotional intelligence on the relationship of intra‐department communications and employee's reaction to organizational change in China.

Based on the literatures in organizational change, organizational communications and emotional intelligence, the authors derived three hypotheses which were tested with data collected in a large state‐owned enterprise (SOE) in the telecommunication industry. Factor analysis and regression analysis were combined for the hypothesis tests.

It was found that intra‐department communications positively influenced employee's reaction to organizational change with employees' emotional intelligence moderating the relationship. When employee's emotional intelligence is higher, intra‐department communication has greater positive effect on employee's reaction to change.

With the adopted western measurement scales, this study was unable to reveal the Chinese contextual aspect of organizational communications. As the data were self‐reported, they may have common source deviation.

To foster and maintain employees' positive reactions to change, managers and organizations may consider developing strategies to improve employees' emotional intelligence, so as to embrace future changes.

This is an initial effort in examining the joint effect of intra‐department communications and employee's emotional intelligence on employee's reaction to organizational change. It may lead to additional research on organizational change management.

The purpose of this paper is to propose an efficient space-time operator-splitting method for the high-dimensional vector-valued Allen–Cahn (AC) equations. The key of the space-time operator-splitting is to devide the complex partial differential equations into simple heat equations and nolinear ordinary differential equations.

Each component of high-dimensional heat equations is split into a series of one-dimensional heat equations in different spatial directions. The nonlinear ordinary differential equations are solved by a stabilized semi-implicit scheme to preserve the upper bound of the solution. The algorithm greatly reduces the computational complexity and storage requirement.

The theoretical analyses of stability in terms of upper bound preservation and mass conservation are shown. The numerical results of phase separation, evolution of the total free energy and total mass conservation show the effectiveness and accuracy of the space-time operator-splitting method.

Extensive 2D/3D numerical tests demonstrated the efficacy and accuracy of the proposed method.

The space-time operator-splitting method reduces the complexity of the problem and reduces the storage space by turning the high-dimensional problem into a series of 1D problems. We give the theoretical analyses of upper bound preservation and mass conservation for the proposed method.

We conducted a pilot study to compare the emotions experienced by Dutch and Chinese students during a face‐to‐face negotiation role play. Emotions play an important role in negotiations because they influence the behaviour and judgments of negotiators. The Data Printer case developed by Greenhalgh was used to examine the patterns of feelings that emerge during negotiations. One hundred and four participants (62 Chinese and 42 Dutch post graduate students) role‐played two different characters who were confronted with a payment dispute regarding the servicing of a defective printer. The results of the MANOVA and of the Factorial Analysis demonstrates that culture as a carrier of social values and norms did influence the emotional reactions of the people socialised in different cultural contexts. The paper concludes that in order to facilitate conflict resolution and interpersonal communication amongst protagonists in mono as well as in inter‐cultural negotiation context individuals should learn to manage their emotions constructively.

Heterogeneous risk disclosure has been proven to improve the efficiency of new stock issuance, but excessive risk disclosure during the IPO may lead to irrational underestimation of the company, which is different from the original intention of management's detailed disclosure. Therefore, this study aims to examine the impact of IPO heterogeneous risk disclosure on earnings management motivations from the information transfer perspective of earnings management.

The sample includes 2,000 listed companies listed firms on Shanghai and Shenzhen Stock Exchanges from 2007 to 2022. This study uses the pretrained ERNIE model to measure text similarity in the prospectus to measure the heterogeneity of IPO risk disclosure.

This study empirically finds that heterogeneous IPO risk disclosure suppresses the opportunistic motivation of earnings management because managers tend to use earnings management to leverage information transmission functions. Such an effect is more pronounced in firms with higher analyst attention, lower marketization levels and non-state-owned. And heterogeneous risk disclosure may inhibit management’s over-investment behavior, thereby reducing the possibility of management engaging in opportunistic earnings management. Besides, price discounts are used to distinguish opportunistic and non-opportunistic earnings management and carry out a quasi-natural experimental design to demonstrate that marketization can enhance the relationship between heterogeneous risk disclosure and earnings management.

This study contributes evidence regarding the economic consequences of managerial earnings management behavior related to heterogeneous IPO risk disclosure. It supports highlighted firms in the IPO risk information disclosure to mitigate potential adverse outcomes through earnings management. This contributes to the literature and enhances information transparency in the capital market, fostering the healthy development of China’s capital market.

The purpose of this study is to examine the fretting wear property of ultra-high molecular weight polyethylene (UHMWPE)-based composites reinforced by different content of attapulgite.

A series of composites were prepared by a hot-pressing method. Fretting tests were carried out using an SRV-IV oscillating reciprocating friction wear tester with a load of 10 N and a frequency of 100 Hz. The morphology of the fracture structure and the worn surface was observed by field-emission scanning electron microscopy, X-ray diffraction and a non-contact three dimensional surface profiler.

With the addition of attapulgite, the microstructure of the composites become more regular, and their heat resistance improved. Furthermore, the friction coefficient and the specific wear rate of the composites with lower filler content reduced compared with that of neat UHMWPE, and the optimum filler content is 1 per cent.

The study investigated the fretting resistance mechanism of the attapulgite in the UHMWPE matrix. The results could help to provide some experimental evidence for the broader application of silicates on the fretting wear resistance of polymers.

This paper aims to focus on studying the addition of nano-tungsten disulfide (WS₂) on fretting wear performance of ultra-high-molecular-weight-polyethylene (UHMWPE).

In this study, the effect of WS₂ content on fretting wear performance of UHMWPE was investigated. The fretting wear performance of the UHMWPE and WS₂/UHMWPE nanocomposites were evaluated on oscillating reciprocating friction and wear tester. The data of the friction coefficient and the specific wear rate were obtained. The worn surfaces of composites were observed. The transfer film and its component were analyzed.

With the addition of 0.5% WS₂, the friction coefficient and specific wear rate increased. With the content increased to 1% and 1.5%, the friction coefficient and specific wear rate decreased. The lowest friction coefficient and specific wear rate were obtained with the addition of 1.5% nano-WS₂. Continuingly increasing content, the friction coefficient and wear rate increased but lower than that of pure UHMWPE.

The research indicated the fretting wear performance related to the content of nano-WS₂ with the incorporation of WS₂ into UHMWPE.

The result may help to choose the appropriate content.

The main originality of the research is to reveal the fretting behavior of UHMWPE and WS₂/UHMWPE nanocomposites. It makes us realize the nano-WS₂ had an effect on the fretting wear performance of UHMWPE.

The purpose of this paper is to investigate the tribological properties of carbonized polydopamine/reduced graphene oxide (CPDA/rGO) composite coatings.

CPDA/rGO composite coatings were prepared using the spray technique and subsequent pyrolysis under argon. The transmission electron microscopy, field-emission scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy revealed the conversion of PDA and GO into CPDA and rGO, respectively.

The results of tribological investigations show that the CPDA/rGO composite coatings with heat treatment at 300°C possess much better friction-reduction and anti-wear properties.

The worn surfaces of the PDA/GO composite films after heat treatment at 300°C were much smoother than that of the copper substrate. The tribofilms containing C, N, O and Cu played an important role on reducing friction and increasing wear resistance.

This paper aims to discuss the effect of frontline employees' emotional labor (surface acting vs. deep acting) on customer satisfaction and the moderating role of responsibility attributions in the situation of robot service failure.

The scenario-based experimental method was designed to perform hypothesis testing and SPSS was used to analyze the data from the 363 questionnaires collected.

The results indicate that (1) employees' emotional labor recovery has a double-edged sword effect. Deep acting improves customer satisfaction, while surface acting undermines the effectiveness of service recovery and leaves customer satisfaction below previous levels. (2) Customers' responsibility attributions for service failure moderate the effect of service recovery.

To the best of the authors’ knowledge, this is the first study to focus on the role of frontline employees' emotional labor in robot service failure contexts, which not only enriches and expands the relevant literature in this domain, but also deepens the understanding of how emotional labor and responsibility attribution effect the customer satisfaction.
