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.

The purpose of this study is to determine the competency characteristics required for the employment of master’s degree students in educational technology.
Abstract
Purpose
The purpose of this study is to determine the competency characteristics required for the employment of master’s degree students in educational technology.
Design/methodology/approach
A combined qualitative and quantitative method was used to consult multiple experts through a modified Delphi method. Competency characteristics were extracted from Chinese recruitment apps, national recruitment websites and university training programs. Ten senior teacher experts who teach educational technology master’s students were consulted through a questionnaire consultation to validate the proposed competency model. The weights of competency characteristics were determined through a combination of the analytic hierarchy process and entropy method.
Findings
The results show that when recruiting educational technology master’s students, more emphasis is placed on operational skills. The majority of companies tend to assess practical abilities rather than theoretical knowledge. Relevant knowledge of educational technology, psychology, computer science and education is considered to be the basic knowledge components of educational technology master’s students, while professional skills are the core skills required for their positions. Therefore, universities need to focus on training, educational technology graduate students in these areas of competence. The study also found that professional qualities (such as physical and mental fitness) and personality traits (interpersonal communication and interaction) receive more attention from companies and are essential competencies for educational technology master’s students.
Originality/value
A competence model for educational technology master’s students is proposed, which includes aspects such as knowledge, personal skills/abilities, professional qualities and personality traits. The competence elements included in this model can serve as reference indicators for universities to cultivate the competence of educational technology master’s students, as well as reference points for recruiting units to help them select talents. This represents a new dimension in research related to the employment of educational technology master’s students. The study enriches the research objects and competence dictionary in the field of competence research.

Abstract
Past research has suggested the influence of family‐oriented collectivistic culture on the behavior and performance of traditional Chinese manufacturing firms. However, insufficient empirical research has been conducted to empirically test the influence. More importantly, insufficient research has been conducted to test how the collectivistic culture in Chinese societies would affect the performance of manufacturing firms. This paper addresses these issues by comparing the behaviors and performance of two groups of firms in China, i.e., investment from overseas Chinese firms and investment from non‐Chinese Western firms, in one of China's fast‐growing manufacturing industries. Interesting differences are found between the overseas Chinese firms and those from other foreign countries. The findings support the influence of societal culture on firms' behavior and performance, but do not support the predictions on performance based on the arguments of cultural distance. This paper concludes with a discussion on implications of the findings for both researchers and practitioners.

Abstract
Purpose
This paper aims to analyse how both Lin’s birthplace identity and his Christian identity contributed to his fruitful public career and to ascertain which identity became the most significant.
Design/methodology/approach
Archival research is the main method used in this paper. The most important archives drawn from are the Daniel Tse Collection in the Special Collection and Archives of the Hong Kong Baptist University Library. Oral history has also been used in this paper to uncover more material that has not yet been discussed in existing scholarly works.
Findings
This paper argues that although Lin’s birthplace identity and social networks helped him to start his business career in Nam Pak Hong and develop into a leader in the local Chaozhou communities, these factors were insufficient to his becoming a respectable member of the Chinese elite in post-war Hong Kong. He became well known not because of his leading position in local Chaozhou communities or any great achievement he had obtained in business but because of his contribution to the development of Christian education. These achievements earned him a reputation as a “Christian educator”. Thus Lin’s Christian identity became more important than his birthplace identity in contributing to his successful public career.
Originality/value
This paper has value in showing how Christian influences interacted with various cultural factors in early Hong Kong. It also offers insights into Lin’s life and motivations as well as the history of the institutions he contributed to/founded. It not only furthers our understanding of the Chinese Christian business elite in early Hong Kong but also provides us with insights when further studying this group of people in other British colonies in Asia.

Abstract
Purpose
The purpose of this research is to study how an approach of culturally‐specific human resource management (HRM) should moderate the relationship between leadership style and employee turnover.
Design/methodology/approach
Questionnaire data were collected from firms in both Shenzhen and Hong Kong. The subjects are 190 leader/member dyads (111 (58 percent) were from mainland China (i.e. Shenzhen), and 79 (42 percent) were from Hong Kong). Hierarchical regression model is adopted to test the hypotheses.
Findings
Collecting empirical data from firms in different regions of China, it was found that a leadership style, i.e. leader‐member exchange (LMX), can have a significant effect on employee turnover. Moreover, the effect of LMX can be moderated by the C‐HRM‐oriented HRM (C‐HRM) approach. The paper concludes with a discussion of the implications of the findings to academic researchers and practitioners. There exist both the direct effect and interactive effect of LMX on employees' organization identity, which in turn affects their turnover. Moreover, collectivism‐oriented HRM (C‐HRM) moderates the relationship between LMX and employees' organization identity. Other conditions being equal, the higher the C‐HRM, the stronger is the positive relationship between LMX and organization identity.
Originality/value
Integrating prior research on LMX, C‐HRM, organization identity and employee retention, this study examines the relationships among LMX, organization identity and employee retention. This is the first study testing these relationships. The findings have several important implications. For instance, this study documents both the direct and moderating effects of C‐HRM on employees' performance for the first time, which will be helpful for the development of new studies on human resource management and cross‐cultural management.

Abstract
Purpose
The purpose of this paper is to propose an effective and efficient solution method for the component allocation problem (CAP) in printed circuit board (PCB) assembly, in order to achieve high‐throughput rates of the PCB assembly lines.
Design/methodology/approach
The investigated CAP is intertwined with the machine optimization problems for each machine in the line because the latter determine the process time of each machine. In order to solve the CAP, a solution method, which integrates a meta‐heuristic (genetic algorithm) and a regression model is proposed.
Findings
It is found that the established regression model can estimate the process time of each machine accurately and efficiently. Experimental tests show that the proposed solution method can solve the CAP both effectively and efficiently.
Research limitations/implications
Although different regression models are required for different types of assembly machines, the proposed solution method can be adopted for solving the CAPs for assembly lines of any configuration, including a mixed‐vendor assembly line.
Practical implications
The solution method can ensure a high‐throughput rate of a PCB assembly line, and thus improve the production capacity without further investment on the expensive PCB assembly equipment.
Originality/value
The paper proposes an innovative solution method for the CAP in PCB assembly. The solution method integrates the meta‐heuristic method and the regression method, which has not been studied in the literature.

Abstract
Purpose
The purpose of this paper is to explore whether or not a preventive replacement model always gives a solution with a specified preventive effect and looks at the relationship between the preventive effect and cost saving.
Design/methodology/approach
The age and block replacement policies with the Weibull failure distribution are considered. Measures of the preventive effect associated with specific maintenance policies are derived.
Findings
The sufficient condition to achieve a given preventive effect is represented graphically as a function of the system's aging intensity and the cost ratio of failure and preventive replacements.
Practical implications
The models developed in the paper will help maintenance engineers to know whether a system is aged or not and then they can make a decision on replacement.
Originality/value
The optimal replacement models considered in this paper give a solution with a good preventive effect only if the maintained system is sufficiently aged. The criterion whether or not the system is sufficiently aged is set by the decision‐maker based on specific maintenance situations or maintenance objectives.

Abstract
This paper studies a production planning problem in printed circuit board (PCB) assembly. A PCB assembly line has several non‐identical placement machines, so the placement times by different machines are various to the same type of components. Several mathematical models are formulated in order to obtain a best assignment of components to machines with the objective of minimizing the cycle time to have the best line throughput. Moreover, the data structures of the models are analyzed and compared with other similar models to search a good available algorithm. Finally, a numerical example is provided to illustrate these models and is solved by a computer package.

Abstract
This study deals with one strategic issue for manufacturing firms operating in Asian emerging markets – technology commitment or investment. It compares two different approaches adopted by international manufacturing firms in China, one of the major emerging markets in the world. Analyzing the data from the 100 largest manufacturing firms (in terms of market share) competing in one of China’s manufacturing industries, i.e. electronics, this paper shows an interesting positive relationship between technology investment and firm performance in China’s manufacturing industries. This paper concludes with a discussion on the implications of the findings.
