Abstract
Polymeric coatings and packaging are often used to enhance the temperature sensitivity of fiber Bragg grating temperature sensors. The high thermal expansion coefficient of the polymer enhances the thermal sensitivity by improving the wavelength shift due to thermal expansion. The adhesion of the polymeric coatings to the silica based optical fiber plays an important role in the wavelength response characteristics of fiber Bragg gratings with respect to temperature. Experiments are done to qualitatively analyze the influence of adhesion. Three‐dimensional finite element simulations have been carried out. Spring elements are used to interconnect the nodes of the meshed models of optical fiber and coating. The effect of adhesion is studied as a function of spring stiffness.

Abstract
Purpose
Zhong-yong thinking is a code of conduct of the Chinese people. The purpose of this study is to explore the relationship among Zhong-yong thinking, social capital, knowledge sharing behavior, and employee survival ability.
Design/methodology/approach
Zhong-yong thinking including multi-thinking, integration and harmony, taking a case study of private enterprise in Guangxi of China. Based on the literature, the establishment of the theoretical model and hierarchical regression analysis are explored.
Findings
The multi-thinking, integration and harmony of Zhong-yong thinking have a significant positive effect on social capital and employee survival ability. In addition, employee survival ability is positively affected by social capital. Moreover, knowledge sharing behavior has a positive moderating between the multi-thinking dimension of Zhong-yong thinking and social capital, and the remaining dimensions have no moderating effect. Knowledge sharing behavior has no moderating effect on the relationship between social capital and employee survival ability.
Practical implications
Zhong-yong thinking and social capital are actively affecting employee survival ability. Therefore, companies need to work harder to improve their employees' Zhong-yong thinking and social capital.
Originality/value
The paper extends Zhong-yong thinking, social capital and employee survival ability literature to fill gaps in how China people require to both access employee survival ability. The policy value of the work is in suggesting ways to facilitate employee survival ability of China.

Abstract
Purpose
The purpose of this paper is to study the influence of friction coefficient of materials with different elastic modulus on the variation of velocity and load under water lubrication and oil lubrication conditions.
Design/methodology/approach
Low-viscosity lubricating oil and water were used as lubricants to test the friction performance of the ball-disc contact friction pair in the lubrication state on the universal micro-tribometer multi-functional friction and wear test system.
Findings
In the same speed range, the lubrication states from soft to rigid materials are not necessarily similar to each other. Generally, the material with low elastic modulus is suitable in low-viscosity lubricant environments, while the material with high elastic modulus has relatively smaller friction coefficients in oil-lubricated environments compared with water lubrication. However, the coefficients of polyethylene, polytetrafluoroethylen and polyoxymethylene are exceeded by rubber’s coefficients under water lubrication in the same experiment environments, and their lubrication states are not affected by lubricants. The friction coefficient of the friction pair decreases with the increase of loads; however, it does not apply to all materials. The friction coefficients of materials with smaller elastic modulus such as rubber under high loads are rather large. Therefore, the elastic modulus of the material under high loads is a factor to be considered.
Originality/value
The Stribeck curves study of the ball-disk contact friction pair comprising soft and rigid materials, whose elastic modulus is from hundreds of GPa to a few of MPa, was carried out. The influence of different speeds, loads and lubricants on the friction coefficient of the friction pair was revealed, which provided a research basis for the selection and matching of friction pair materials.

Abstract
Purpose
This study aims to investigate whether higher value creation leads to higher value appropriation and to identify the boundary conditions in a buyer–supplier relationship that can explain why a particular supplier can appropriate higher value than others.
Design/methodology/approach
The study uses questionnaire surveys. The sample of the survey has 150 publicly-listed supplier firms in Taiwan. The unit of analysis is the buyer–supplier relationship.
Findings
In the buyer–supplier relationship, suppliers’ bargaining power, partnership and a supplier’s original brand manufacturing (OBM) business can strengthen the positive relationship between value creation and value appropriation.
Research limitations/implications
This study adopts the unilateral viewpoint of suppliers; however, some constructs might require dyadic evaluation. This study only explores the spillover effect of OBM business on the relationship between value creation and appropriation.
Practical implications
The spillover effect of a supplier’s OBM business in a buyer–supplier relationship allows the buyer to share more common benefits and the supplier to capture more private benefits as compensation. By broadening its customer base, a supplier can increase its bargaining power. A supplier can also maintain a strategic partnership with each essential buyer.
Originality/value
To avoid the dark-side effect of partnership, the model provides the contingency that a supplier can capture more value from a buyer–supplier relationship.

Abstract
Purpose
The aim of this paper is to illustrate how scholars may adopt a multi‐method – not just multidisciplinary – approach on research on conflict management. Taking the Diaoyu Islands as a case, the author draws on literature from management, political sciences, war, military studies, history, etymology and culture. In the process, the author deepens, enriches and expands the Thomas‐Kilman (T‐K) model for mapping out possible solutions in resolving conflicts: not just between people at workplaces but for between states as well. For instance, the author explains why the Diaoyu Islands conflict, if not amicably resolved may well lead to obliteration (integrated as part of the model) in resolving the conflict via a nuclear outbreak. Third World War may just be sparked off with Russia aligned with China against Japan and the USA.
Design/methodology/approach
Of all the issues in management, conflict management is the most culturally embedded. Through a multi‐method approach, the author illuminates the complexity of the Diaoyu Islands case. Literature from past empirical war studies are reviewed to suggest the geography of the islands (proximity, borderless, richness of resources) makes war highly probable. Past Chinese‐Japanese hatred (utilizing visual imagery), antagonism and guanxi are reviewed in exploring their impacts on outcomes (see model). Etymological research is attempted using English, Japanese and Chinese words, characters and pictograms that are related to concepts within the T‐K model. To better grasp how young Chinese feel towards the Diaoyu Islands and the Japanese, the author conducted some field research in Harbin, China. The continuing Chinese angst against Japanese is explained through war imagery: there remains in young Chinese an unquenchable thirst for exacting revenge on the Japanese. In a search to uncover ways of resolving the dispute, a further, extended study is undertaken on ancient Chinese pictograms: for example, whether a 5,000 years old Chinese concept of compromise zhe zhong (Graphic 1; oracular bones) or splitting into halves may be relevant. The role of time in conflict management is discussed in relation to the Diaoyu Islands.
Findings
By providing the WWII visual imagery as a backdrop to Chinese‐Japanese antagonism, the author explains to readers why the Diaoyu Islands is such a complex case to resolve. Also in his fieldwork, he highlights that the younger Chinese are as equally indignant about Japanese unethical grabbing, “thieving” behaviour. In their minds, such behaviour harks back to the blatant seizure of Manchuria and Japanese puppetry of Manchukuo. Through the Diaoyu Islands case, the T‐K model and theory of conflict management is broadened, enriched and enhanced. The paper illustrates how in conflicts that involve cultures are very different from the West, for instance very ancient civilizations like China and India, authors should take a multi‐method approach and explore the issues and search for solutions far more deeply.
Originality/value
Very few scholars seek to integrate the two streams of research in resolving conflict as illustrated through this paper: management and social sciences (e.g. political sciences, military and war studies). Conflict is about people and therefore integral use of multi‐methods needs to be used.

This review aims to give a critical view of the wheel/rail high frequency vibration-induced vibration fatigue in railway bogie.
Abstract
Purpose
This review aims to give a critical view of the wheel/rail high frequency vibration-induced vibration fatigue in railway bogie.
Design/methodology/approach
Vibration fatigue of railway bogie arising from the wheel/rail high frequency vibration has become the main concern of railway operators. Previous reviews usually focused on the formation mechanism of wheel/rail high frequency vibration. This paper thus gives a critical review of the vibration fatigue of railway bogie owing to the short-pitch irregularities-induced high frequency vibration, including a brief introduction of short-pitch irregularities, associated high frequency vibration in railway bogie, typical vibration fatigue failure cases of railway bogie and methodologies used for the assessment of vibration fatigue and research gaps.
Findings
The results showed that the resulting excitation frequencies of short-pitch irregularity vary substantially due to different track types and formation mechanisms. The axle box-mounted components are much more vulnerable to vibration fatigue compared with other components. The wheel polygonal wear and rail corrugation-induced high frequency vibration is the main driving force of fatigue failure, and the fatigue crack usually initiates from the defect of the weld seam. Vibration spectrum for attachments of railway bogie defined in the standard underestimates the vibration level arising from the short-pitch irregularities. The current investigations on vibration fatigue mainly focus on the methods to improve the accuracy of fatigue damage assessment, and a systematical design method for vibration fatigue remains a huge gap to improve the survival probability when the rail vehicle is subjected to vibration fatigue.
Originality/value
The research can facilitate the development of a new methodology to improve the fatigue life of railway vehicles when subjected to wheel/rail high frequency vibration.

Abstract
Purpose
This policy review paper is an analysis of the Double Reduction Policy (DRP) of China that was promulgated in July 2021. It looks into its rationale as well as different stakeholders' early reactions to the policy.
Design/methodology/approach
Critical policy analysis (CPA) method was used to identify (1) the artefacts, such as language, objects and acts, that were significant carriers of the DRP; (2) communities of meaning, interpretation, speech and practice that are relevant to the DRP and its implementation; (3) the local discourses relevant to the DRP; and (4) the tension points and their conceptual sources (affective, cognitive and/or moral) by different DRP stakeholders. As per the comparative education field, this paper compares the pre-DRP and post-DRP periods to tease out how the policy affects different stakeholders of education.
Findings
The DRP in China could be attributed to diverse factors such as demography, socialist economic and developmental visions and manpower structure. The implementation of the DRP has generated uneven reactions among different stakeholders and geographical regions both in speed and scale. While education stakeholders have no choice but to adopt the policy, they face challenges derived from a sudden halt of private educational resources and subsequent increased duties of parents and schools.
Originality/value
The significance of this early policy analysis lies in offering an insight into education development in China by analysing and deliberating the DRP from different perspectives.

Abstract
Purpose
This paper aims to make a call for the establishment of a new research journal: a likely title for which would be Chinese Public Management. The background to this is clearly set out here for posterity’s sake. The review of selected papers unveils an emerging trend amongst Chinese researchers for undertaking deeper, cluster-based analyses. See, for example, the insights presented in this issue concerning competitiveness in China’s automobile industry.
Design/methodology/approach
A diary-like account has been made of the series of recent events that sparked the author’s interest in creating a journal to be known as Chinese Public Management. Why is there currently this focus on empirical research for public policy? From the author’s five years’ work for a serial visiting professorship across China, he has found that there are now well-established, substantial databases dedicated to the subject. Even more importantly – as this paper illustrates – a growing community of scholars has become keen to embark upon an in-depth, quantitative research. Perhaps, for the new journal, we would need an editor concentrating specifically on databases. Furthermore, undertaking scholarly work that is still of practical relevance for guiding authorities in their formulations of public policy will add a whole new dimension to the available research.
Findings
There is scope for a new endeavor that documents management research within the public sector in China. This may be seen as a sister journal for “Chinese Management Studies” that focuses on the other, much larger Chinese sector, that is, governmental organizations.
Originality/value
This paper documents the emergence of the necessity for a new journal about management in China.

Abstract
Purpose
The purpose of this paper is to examine cross-cultural differences in managerial discretion and the extent to which variations and interaction of cultural practices and values affect the degree of freedom in decision making that is accorded to executives. This paper offers a holistic approach to investigating culture in addition to acknowledging its paradoxical nature.
Design/methodology/approach
Using a panel of prominent management consultants to rate discretion across 18 countries, the authors further develop the national-level construct of managerial discretion by empirically investigating the influence of cultural practices and values on CEOs’ discretion.
Findings
The study reveals that cultural values moderate the relationship between cultural practices and managerial discretion for three cultural dimensions: individualism, uncertainty tolerance and power distance (PD). By adopting the logic of marginal utility, the authors also show that the more a society values individualism, uncertainty tolerance and PD, the weaker the effect of their practices on managerial discretion.
Originality/value
Few research has attempted to assess both cultural values and practices in relation to managerial discretion. By showing the mechanism in which culture affects the level of managerial discretion, the authors offer new theoretical insights and practical implications, overall contributing to the field of cross-cultural and strategic management. Finally, this will offer CEO’s a new perspective of leveraging culture as a tool, enhancing their decision-making capabilities in the aim of improving organizational performance.

Abstract
Purpose
This study aims to identify and analyze how Internet of things (IoT) technology affects supply chain management (SCM) performance.
Design/methodology/approach
A systematic literature review was conducted (using Scopus, JSTOR, Emerald, ProQuest, Science Direct and Web of Science) covering a 20-year timeframe (2000–2020). Out of 2,572 papers identified, 171 peer-reviewed papers from the most important journals were selected. Content analysis was used following the Global Supply Chain Forum (GSCF) SCM framework.
Findings
Regarding the GSCF SCM framework processes, most IoT-based studies have addressed improving order fulfilment, manufacturing flow management and demand management processes. However, no studies addressing the Supplier relationship management process were identified, suggesting that IoT-based applications are perceived to add more value in downstream than upstream SCM processes. The importance of using enabling technologies to realize the potential of value generation of IoT was also revealed. Findings suggest new research avenues related to product development and commercialization process, the supplier relationship management process, the returns management process, servitization strategies, new SCM models and new business models.
Research limitations/implications
The review encompasses only academic papers from journals considered the most relevant (retrieved from specific databases), using the impact factor as the quality criterion.
Practical implications
The findings can help business managers better understand the potential of IoT technology, such as the main applications identified in the literature and their impacts on SCM processes. Their importance in enabling technologies to leverage SCM performance is identified and the emerging SCM models/business models that IoT deployment can enable are highlighted.
Originality/value
This study contributes to filling a gap in the literature using a systematic literature review of how IoT technology affects SCM performance through content analysis, using an SCM framework to clarify which SCM processes are affected. Academic articles from the most important journals from 2000 to 2020 are identified.
