Abstract
Purpose
The purpose of this paper is to study the effects of single parameters for temperature characteristics of oil film in port plate pair and the relationship of calculated results and experimental results under different viscosity.
Design/methodology/approach
The paper established the mathematical model of oil film of port plate pair, calculated the energy equation of port plate pair, simulated for the oil film and temperature distribution and selected different kinds of lubricants to analyze the calculated value and the experimental value.
Findings
The results show: temperature rise of port plate pair is reduced with the increase of oil viscosity; temperature rise of port plate pair is decreased with rise of initial oil film thickness; temperature rise of port plate pair is increased with the rise of cylinder body speed, inclination angle and sealing belt width; and through the comparison of calculated value and experimental value, under the same viscosity and cylinder speed, experimental results are bigger.
Originality/value
This paper used the methods that the temperature of port plate pair was calculated numerically, and the results were consistent with experimental results, so it can get high precision.

Abstract
This paper investigates the foreign ownership structure of service equity joint ventures (EJVs) in China. In less than 20 years, China has emerged from a closed economy to become the second largest recipient of foreign direct investment (FDI) in the world. Now that China is a member of the World Trade Organisation, liberalisation of FDI is expected to accelerate even further. Despite the fact that an increasing proportion of FDI in China is in the form of equity joint ventures in the service sector, little is known of the ownership structure of service EJVs. Using a database of 6,430 foreign EJVs, in China from 1984 to 1996, this paper shows that foreign equity ownership differs significantly between service and manufacturing EJVs with foreign ownership generally being higher in service EJVs. The overall results also suggest that the gradual liberalisation of FDI in the service sector by Chinese authorities has had a positive effect on foreign equity ownership.

Abstract
Rivers flowing through the land are a source of life. They have different importance and functions such as for drinking, sailing, irrigating crops, generating electricity, sightseeing, fishing, and so on. In addition, animals like amphibians, birds, and mammals also live and propagate near the river environment. Therefore, rivers are ecosystems for some animals and plants that are special, rare, or on the brink of extinction (Water Resources Agency, Ministry of Economic Affairs, 2006).

Abstract
Purpose
Despite the considerable research into China's industrial relation system, little attention has been focused on what do Chinese unions at the enterprise level do and how their daily work influences employees' work-related outcomes. Drawing on the theory of planned behavior, this paper aims to examine the impact of Chinese enterprise union practices on employees' change-oriented organizational citizenship behavior through the mediating roles of psychological safety, perceived insider status, and role breadth self-efficacy.
Design/methodology/approach
Data were collected from 450 employees at 45 unionized enterprises in China through a three-wave survey. Multilevel analyses were conducted to test the hypothesized effects.
Findings
Chinese enterprise union practices positively predicted change-oriented organizational citizenship behavior. Critically, psychological safety and role breadth self-efficacy mediated the positive relationship between Chinese enterprise union practices and change-oriented organizational citizenship behavior.
Originality/value
This study provides new evidence on the effectiveness of Chinese enterprise union practices from a perspective of employees' work-related outcomes. It also enriches the existing literature on antecedents of change-oriented organizational citizenship behavior and provides a “planned” perspective to understand the mechanism that underlies the relationship between Chinese enterprise union practices and change-oriented organizational citizenship behavior.

Abstract
Purpose
Revenue management (RM) is a significant technique to improve revenue with limited resources. With the macro environment of dramatically increasing transit capacity and rapid railway transport development in China, it is necessary to involve the theory of RM into the operation and decision of railway passenger transport.
Design/methodology/approach
This paper proposes the theory and framework of generalized RM of railway passenger transport (RMRPT), and the thoughts and methods of the main techniques in RMRPT, involving demand forecasting, line planning, inventory control, pricing strategies and information systems, are all studied and elaborated. The involved methods and techniques provide a sequential process to help with the decision-making for each stage of RMRPT. The corresponding techniques are integrated into the information system to support practical businesses in railway passenger transport.
Findings
The combination of the whole techniques devotes to railway benefit improvement and transit resource utilization and has been applied into the practical operation and organization of railway passenger transport.
Originality/value
The development of RMRPT would provide theoretical and technical support for the improvement of service quality as well as railway benefits and efficiency.

Abstract
Purpose
Compared to other areas in China, Chaoshan region in Guangdong province has a more developed clan system set within a rural landscape. This paper aims to explore the relationship between the social structure (family–clan) and spatial form (housing settlement) of clan-organized rural China to understand the spatial form represented by “family and clan.”
Design/methodology/approach
By examining Dongli village and Huayao village, this paper outlines the typical path of spatial representation: dwelling of individual’s core family → mansion of the big family → settlement of a single clan → co-settlement of several clans. Moreover, it identifies three critical elements of the spatial representation: prototype (the spatial representation of the etiquette system); order (a hierarchical space set by the patriarchal system); and boundary (constructed on both physical and mental facts).
Findings
All elements indicate that descendants of migrants from the North maintain their self-identity and discipline clan members by planning the ideal space.
Research limitations/implications
The findings contribute to the ongoing discussions regarding how local cultural and historical experiences can influence renewed designs of traditional settlement areas (Aksulu and Eryildiz, 2003) and how digital means can facilitate updating designs of traditional buildings (Han et al., 2017). Such planning and design should involve greater public participation, considering the impact on residents’ daily lives (Pandya, 2005).
Originality/value
This paper contributes to the understanding of the relationship between cultural values and the spatial form of residential settlements in Chinese history.

Abstract
We build on the resource-based view and extend entry mode research by focusing on firms’ intention to transfer different resources from the parent firm to its overseas subsidiary. In line with our hypotheses, we find that parent firms that plan to transfer high levels of intangible resources to their foreign subsidiaries tend to choose wholly owned subsidiaries, while firms that intend to transfer high levels of tangible resources tend to choose international joint ventures. Moreover, we find that these relationships are moderated by institutional distance. We test our hypotheses using unique primary data from a sample of 128 foreign subsidiaries in the People’s Republic of China. Our results have important theoretical implications for international business strategy research as they develop further existing entry-mode theories.

Abstract
Purpose
This paper aims to develop a flexible manufacturing method for multimaterial sand molds to realize efficient additive manufacturing of multimaterial sand molds.
Design/methodology/approach
To study the influence of multimaterial sand laying process parameters on the quality of powder bed and optimize the design of multimaterial sand laying device. Numerical simulation and X-ray Computed Tomography are used to study the penetration behavior and curing morphology of resin in different sand particles.
Findings
The surface roughness and porosity of the multimaterial powder bed that meet the requirements of sand-based additive manufacturing can be obtained under the optimal printing process, that is, the sanding speed of 140.0 mm/s and sanding roller diameter of 15.0 mm. The resin penetration process of the multimaterial sand molds shows a pattern of transverse expansion and longitudinal penetration. In terms of the resin curing morphology, the maximum thickness of the resin film layer of zircon sand reaches 30.5 ± 1.0 µm, which has the best tensile property, followed by silica sand and the thinnest resin film layer of chromite sand.
Originality/value
In this work, a highly flexible integrated combined sand-laying device suitable for multimaterial sand-laying tests is developed, which can obtain a multimaterial powder bed that meets the needs of sand additive manufacturing. Subsequent casting print tests also verify that the program can meet the needs of multimaterial sand mold additive manufacturing.

Abstract
Allocating risk in public–private partnership (PPP) projects based on public–private parties’ risk management (RM) capabilities is a condition for success of these projects. In practice, however, risks are allocated to these parties beyond their respective RM capabilities. Too much risk is often assigned to the private or public party, resulting in poor RM and costly contract renegotiations and terminations. This chapter proposes a methodology based on fuzzy set theory (FST) in which decision makers (DMs) use linguistic variables to assess and calculate RM capability values of public–private parties for risk events and to arrive at risk allocation (RA) decisions. The proposed methodology is based on integrating RA decision criteria, the Delphi method and the fuzzy synthetic evaluation (FSE) technique. The application of FSE allows for the introduction of linguistic variables that express DMs’ evaluations of RM capabilities. This provides a means to deal with the problems of qualitative, multi-criteria analysis, subjectivity and uncertainty that characterise decision-making in the construction domain. The methodology is outlined and demonstrated based on empirical data collected through a three-round Delphi survey. The public–private parties’ RM capability values for land acquisition risk are calculated using the proposed methodology. The methodology is helpful for performing fuzzy-based analysis in PPP projects, even in the event of limited or no data. This chapter makes the contribution of presenting a RA decision-making methodology that is easy to understand and use in PPP contracting and that enables DMs to track calculations of RM capability values.
