This paper aims to reveal the tribochemical reaction mechanism on the nano-cutting interface between HMX crystal and diamond tool.
Abstract
Purpose
This paper aims to reveal the tribochemical reaction mechanism on the nano-cutting interface between HMX crystal and diamond tool.
Design/methodology/approach
Molecular dynamics simulation of HMX crystal nano-cutting by the reactive force field is carried out in this paper. The affinity of activated atoms and friction damage at the different interface have been well identified by comparing two cutting systems with diamond tool or indenter. The analyses of reaction kinetics, decomposition products and reaction pathways are performed to reveal the underlying atomistic origins of tribocatalytic reaction on the nano-cutting interface.
Findings
The HMX crystals only undergo damage and removal in the indenter cutting, while they appear to accelerate thermal decomposition in the diamond cutting. the C-O affinity is proved to be the intrinsic reason of the tribocatalytic reaction of the HMX-diamond cutting system. The reaction activation energy of the HMX crystals in the diamond cutting system is lower, resulting in a rapid increase in the decomposition degree. The free O atoms can induce the asymmetric ring-opening mode and change the decomposition pathways, which is the underlying atomistic origins of the thermal stability of the HMX-diamond cutting system.
Originality/value
This paper describes a method for analyzing the tribochemical behavior of HMX and diamond, which is beneficial to study the thermal stability in the nano-cutting of HMX.

Abstract
Purpose
The purpose of this paper is to explore the determinants of entrepreneurs’ subjective social status perception (SSP) on firm international behaviors based on the upper echelons theory and social class theory.
Design/methodology/approach
To test the hypotheses, the authors studied a large sample of 10,823 small- and medium-sized private Chinese enterprises from 2006 to 2014.
Findings
The results showed that entrepreneurs with higher status perception prefer international activity and firms have higher export intensity and intention. In addition, the social capital of entrepreneurs and institutional environment amplifies the positive relationship between SSP and international behavior.
Originality/value
This paper contributes to research on the upper echelon of management and extends our understanding of how managerial social characteristics influence international strategic decision-making. Besides, it also contributes to the emerging stream of social status research in international expansion studies and expand researchers’ limited understanding of the effects of social status in business settings.

Abstract
Purpose
More and more firms are utilizing social media as a distribution channel to sell products. By establishing business accounts on social media firms provide information service to strengthen their relationship with customers and boost sales. The purpose of this paper is to investigate the pricing, information service provision and channel strategies of firms who sell products through social media.
Design/methodology/approach
The authors use a game theoretical model to study a dual-channel supply chain consisting of one manufacturer and one retailer. Two scenarios are considered – under one scenario the manufacturer and under the other the retailer, respectively, solely provides information service. Both firms’ pricing decisions and profits are compared.
Findings
The authors find that in the dual-channel model with either the manufacturer or the retailer providing information service to enhance the demand: a firm that has stronger social ties with customers is willing to provide more information services; when the manufacturer provides information service, it charges a direct price higher than the wholesale price, and whether the direct-channel price exceeds the retail price depends on the strength of the manufacturer’s social ties with customers; when the retailer provides information service, the direct price is equal to the wholesale price, both lower than the retail price; and a firm always prefers itself rather than the other firm to provide information service. However, the whole supply chain is better off if the manufacturer rather than the retailer provides information service.
Research limitations/implications
Besides the relationship between firms and customers, the peer relationship among customers also impacts the supply chain performance, which might be studied in the future.
Originality/value
The study is novel in theoretically exploring the influence of firms’ social relationship with customers on firms’ pricing and channel strategies.

Abstract
Purpose
This paper aims to comprehensively achieve the requirements of high assembly precision and low cost, a precision-cost model of assembly based on three-dimensional (3D) tolerance is established in this paper.
Design/methodology/approach
The assembly precision is related to the tolerance of parts and the deformation of matching surfaces under load. In this paper, the small displacement torsor (SDT) theory is first utilized to analyze the manufacturing tolerances of parts and the assembly deformation deviation of matching surface. In the meanwhile, the extracting method of SDT parameters is proposed and the assembly precision calculation model based on the 3D tolerance is established. Second, an integrated optimization model based on the machining cost, assembly cost (mapping the deviation domain to the SDT domain) and quality loss cost is built. Finally, the practicability of the precision-cost model is verified by optimizing the horizontal machining center.
Findings
The assembly deviation has a great influence on cost fluctuation. By setting the optimization objective to maximize the assembly precision, the optimal total cost is CNY 72.77, decreasing by 16.83 per cent from the initial value, which meets economical requirements. Meanwhile, the upper bound of each processing tolerance is close to the maximum value of 0.01 mm, indicating that the load deformation can be offset by appropriately increasing the upper bound of the tolerance, but it is necessary to strictly restrict the manufacturing tolerances of lower parts in a reasonable range.
Originality/value
In this paper, a 3D deviation precision-cost model of assembly is established, which can describe the assembly precision more accurately and achieve a lower cost compared with the assembly precision model based on rigid parts.

Abstract
Purpose
This study aims to explore the impact of well-educated young Chinese employees’ notions of work on their conflict management styles in the increasingly turbulent workplace to help better manage work-related conflict in the time of transition in China.
Design/methodology/approach
Self-administered questionnaires were used to collect data from over 400 young Chinese employees. The data were first factor analyzed to explore the underlying dimensions of contemporary work notions in China’s transition period. Hierarchical regression analysis was then conducted to explore the relationship between dimensions of work notions and conflict management styles.
Findings
The results showed that well-educated young Chinese employees’ notions of work consisted of sense of control, fulfilling and rewarding, holistic concerns, personal growth and development and meaningfulness. The results further indicated that young Chinese employees with strong needs to satisfy individual interests in their work tend to use competitive methods to manage work-related conflicts, employees with strong needs to satisfy group interests in their work prefer to use collaborative methods and those who believe in collective efforts in achieving individual goals through group goals’ obtainment are more likely to use collaborative and compromising approaches.
Originality/value
This study provides a new perspective to manage work-related conflict in the Chinese context. The findings of this study are able to help enrich conflict management theories in China and suggest insightful conflict resolution approaches to work-related conflicts in China’s changing environment. This study also helps bridge the research gap between work notions and conflict management styles. The results of this study can greatly facilitate Chinese companies’ endeavors toward crafting a more innovative workforce and help improve employee performance in China’s transition to industrialization.

This qualitative study explores how Chinese senior outbound tourists perceive support from their adult children and what kinds of support they desire.
Abstract
Purpose
This qualitative study explores how Chinese senior outbound tourists perceive support from their adult children and what kinds of support they desire.
Design/methodology/approach
Qualitative data were collected from semi-structured interviews with 26 participants. Transcribed interviews were analysed via thematic analysis.
Findings
This study captured the contradictory feelings of different types of Chinese senior outbound tourists (i.e. independent, neutral, and dependent) according to the degree of desire for support from their adult children. The results further identified the real desires among Chinese senior outbound tourists for children's attitudinal support, caring support, appropriate financial support, companionship, and timing support.
Research limitations/implications
Since this qualitative research is based on small samples with typical social and cultural characteristics, our research results only describe an existence. Our findings provide insight into the existence of the phenomenon, rather than allowing the results to be generalized to the wider population (Gram et al., 2019).
Practical implications
The tourism industry could develop products to alleviate such feelings. Integrating the concept of filial piety into adult children's support for their parents' overseas travel can not only meet parents' expectations but also relieve parents' ambivalence. Destination operators and travel agencies could thus design mixed products targeting Chinese elderly parents and their adult children by providing activities for both generations. Purchasing behaviour represents a type of emotional and instrumental support for the elderly. Destination operators and travel agencies can also launch products suitable for in-depth outbound travel that cater to adult children's leisure travel while meeting the elderly's travel needs.
Originality/value
This study also extends both intergenerational support theory and intergenerational ambivalence theory regarding Chinese senior outbound tourists.

Abstract
Purpose
The purpose of this study is to present a holistic review of journal articles on value cocreation in the tourism and hospitality field. By distinguishing similarities and differences in the contexts of China and other regions, the authors identify targeted research directions.
Design/methodology/approach
This study collected 438 English articles and 31 Chinese articles on value cocreation in tourism and hospitality published in the Web of Science, Scopus and China National Knowledge Infrastructure online databases. After analyzing the study location of all articles in the sample, the authors identified 79 English-language articles that adopted China as the context of the study. The first data set included non-China-focused publications and the second data set included China-focused publications. A comparative bibliometric methodology was conducted.
Findings
The results indicate similarities and differences between the two data sets in terms of research methods, topics and future research directions. Seven major concepts were identified in the first data set: hospitality value cocreation; the value generation process; key stakeholders; outcome variables; the application of service-dominant logic; peer-to-peer accommodation and destination management. Four research focuses were identified in the second data set: the application of customer-dominant logic; the value generation process; resource integration and the cocreation experience.
Research limitations/implications
This research contributes to the understanding of tourism and hospitality cocreation systems through literature analysis and encourages future research on the nexus of the Chinese and global contexts. This systematic investigation extends the concept of value cocreation by integrating its implementation process and value categories and further evaluates the consequences and benefits of value cocreation, which helps clarify how winners and losers can adjust their strategies accordingly.
Originality/value
The originality of this paper lies in the adopted comparative bibliometric analysis which comprehensively reviewed and compared the characteristics of value cocreation research across two contexts. In addition, the study dialectically assesses Chinese tourism cocreation phenomena and their impacts from a global perspective.

Abstract
Purpose
The functionality and reliability of an overhauled aero-engine is determined by all configuration changes in the overhaul process. Identifying, recording, auditing, tracking and tracing of configuration modifications are significant and meaningful. Considering the barriers to these goals, this paper aims to put forward an approach to configuration management in the aero-engine overhaul process.
Design/methodology/approach
The overhaul configuration management model is proposed to describe an aero-engine’s configuration evolution trajectory in the overhaul process. The controlling and auditing procedures are put forward to control and audit parts’ return-to-zero statuses and overproof statuses. And some searching algorithms are also designed to enable tracking and tracing of the configuration status along the time coordinate, or get a snapshot of an aero-engine’s configuration at a certain time. The above model, procedures and algorithms have been implemented and adopted to fulfill the configuration management requirements in the aero-engine overhaul process.
Findings
The approach is effective in identifying, recording, controlling, auditing, tracking and tracing configuration changes in the overhaul process.
Practical implications
The approach’s implementation and adoption present a practical example for aero-engines’ configuration management issue in the overhaul process.
Originality/value
The work proposes an original aero-engine configuration management solution for the overhaul process and enables a reliable and accurate configuration management mode.
