Abstract
Purpose
The purpose of this paper is to examine the uniqueness of management development in China during 1990 and 2010 as represented by the MBA education, and to explore its successes and challenges in the Chinese transitioning context.
Design/methodology/approach
The authors adopted an approach that integrated content analysis of literature, historical data and interviews.
Findings
It was found that successful practices such as the National MBA Education Supervisory Committee, the top‐down approach by the government, the emphasis on international collaborations and faculty development, national MBA entrance examinations, and other related measures have maintained the MBA education system on its current development course, while challenges from the ever‐changing context, the balance between internationalization and localization, curriculum design with the Chinese characteristics will continue to shape the future of MBA education in China.
Practical implications
Copying from others for management development in the initial stage may be feasible, but it is the localization that ensures flexibility and sustainability.
Originality/value
There has been insufficient systematic assessment of MBA education in China. This paper examined MBA practices and challenges in the past two decades of development and offers policy implications for future program development.

Abstract
Purpose
The purpose of this paper is to investigate how R&D originality functions in an open innovation process after the introduction of knowledge spillovers (KSs).
Design/methodology/approach
To examine the research framework, the authors use hierarchical regression based on questionnaire data from 211 emerging enterprises in China.
Findings
Consistent with the proposed framework, the authors find that the KS effect mediates the positive relationship between openness and innovation performance. In addition, R&D originality weakens the impact of the KS effect on innovation performance.
Research limitations/implications
One limitation is that the questionnaire survey the authors choose for data collection has some natural defects; furthermore, the testing method and research framework need to be improved.
Practical implications
Several implications of the findings for managerial practices are discussed.
Originality/value
First, the research expands the existing theoretical construct by introducing the KS effect into the open innovation process; second, the authors reveal the negative impact of R&D originality on the open innovation process.

Abstract
Purpose
Browsing knowledge documents in a peer-to-peer (P2P) environment is difficult because knowledge documents in such an environment are large in quantity and distributed over different peers who organize the documents according to their own views. This paper aims to propose a method for constructing a personal knowledge map for a peer to facilitate knowledge browsing and alleviate information overload in P2P environments.
Design/methodology/approach
The research presents a method for constructing a personal knowledge map. The method adopts an ontology-concept-tree-based classification algorithm to recognize a peer’s personal knowledge structure and construct a personal knowledge map, and uses a self-organizing map algorithm to cluster and visualize the knowledge documents. The correctness of the created knowledge map is evaluated with a collection of abstracts of academic papers.
Findings
The method for constructing a personal knowledge map is the main finding of this research. The evaluation shows that the created knowledge map is good in quality.
Research limitations/implications
The proposed method provides a way for P2P platforms to understand their users’ knowledge background, as well as to improve the P2P platform environment. However, the proposed method will not help a peer when he has nothing in his individual knowledge document repository (i.e. the “cold start” problem). The method also requires a relatively good ontology base for a P2P document sharing system to use the method effectively.
Originality/value
It is novel that the proposed method organizes the knowledge documents related to a peer’s knowledge background into a personal knowledge map. Moreover, the created knowledge map combines the advantages of a hierarchical display and a map display. It has values for a distributed P2P environment to facilitate users’ knowledge browsing and to alleviate information overload.

Abstract
Purpose
The purpose of this paper is to examine the significant challenges school administrators encountered leading a one-to-one laptop school and what vision school administrators have for one-to-one laptop use in the classroom.
Design/methodology/approach
The methodology for this study was a case study approach. In total, 15 school administrators were interviewed from the Western region of the USA.
Findings
Results from the study indicated that significant challenges for school administrators were budgeting and sustaining the initiative, and negotiating and setting expectations for instructional use with teachers. School administrators also envisioned one-to-one laptop use as a mean to enhance student-centered learning and inquiry.
Research limitations/implications
Further research is needed which examines how school administrators make financial decisions in regards to sustaining one-on-one laptop initiatives and how they manage conflict with teachers in respect to one-to-one laptop instruction.
Originality/value
Minimal literature exists which examines the challenges and vision of school technology leaders. Policy-makers and school administrators can use the findings to recreate teacher evaluation forms, develop conflict management strategies and teaching standards that are aligned and conducive to one-to-one laptop schools.

Abstract
Purpose
The paper aims to discuss the amended provisions relating to protection of minority shareholders (PMS) in the newly amended Chinese Company Law and evaluate whether it adequately protects the interests of minority shareholders.
Design/methodology/approach
In total, 26 cases will be examined by discussing the characteristics of the relevant parties involved, specifically plaintiffs, defendants, their lawyers, judges and also the grounds of complaint. A comparison will be made between the cases decided by following the first Company Law (1994) and the cases decided in accordance with the newly amended Company Law (2006).
Findings
The findings indicate that the amended Company Law has removed certain drawbacks in PMS present in the first Company Law (1994) but the New Company Law can protect interests of minority shareholders only to a certain extent. Further amendments are still needed.
Originality/value
This is one of the first studies to actually examine the implementation of PMS‐related provisions in the newly amended Company Law.

Abstract
The minimum wage has been regarded as an important element of public policy for reducing poverty and inequality. Increasing the minimum wage is supposed to raise earnings for millions of low-wage workers and therefore lower earnings inequality. However, there is no consensus in the existing literature from industrialized countries regarding whether increasing the minimum wage has helped lower earnings inequality. China has recently exhibited rapid economic growth and widening earnings inequality. Since China promulgated new minimum wage regulations in 2004, the magnitude and frequency of changes in the minimum wage have been substantial, both over time and across jurisdictions. The growing importance of research on the relationship between the minimum wage and earnings inequality and its controversial nature have sparked heated debate in China, highlighting the importance of rigorous research to inform evidence-based policy making. We investigate the contribution of the minimum wage to the well-documented rise in earnings inequality in China from 2004 to 2009 by using city-level minimum wage panel data and a representative Chinese household survey, and we find that increasing the minimum wage reduces inequality – by decreasing the earnings gap between the median and the bottom decile – over the analysis period.

Abstract
Purpose
Researchers continue to address the concept of self-disclosure because it is foundational for helping social networking sites (SNS) function and thrive. Nevertheless, the authors' literature review indicates that uncertainty remains around the underlying mechanisms and factors involved in the self-disclosure process. The purpose of this research is to better understand the self-disclosure process from the lens of dual-process theory (DPT). The authors consider both the controlled factors (i.e. self-presentation and reciprocity) and an automatic factor (i.e. social influence to use an SNS) involved in self-disclosure and broaden The authors proposed a model to include the interactive facets of enjoyment.
Design/methodology/approach
The proposed model was empirically validated by conducting a survey among users of WeChat Moments in China.
Findings
As hypothesized, this research confirms that enjoyment and automatic processing (i.e. social influence to use an SNS) are complementary in the SNS self-disclosure process and enjoyment negatively moderates the positive relationship between controlled factor (i.e. self-presentation) and self-disclosure.
Originality/value
Theoretically, this study offers a new perspective on explaining SNS self-disclosure by adopting DPT. Specifically, this study contributes to the extant SNS research by applying DPT to examine how the controlled factors and the automatic factor shape self-disclosure processes and how enjoyment influences vary across these processes – enriching knowledge about SNS self-disclosure behaviors. Practically, the authors provide important design guidelines to practitioners concerning devising mechanisms to foster more automatic-enjoyable value-added functions to improve SNS users' participation and engagement.

Abstract
Purpose
The purpose of this paper is to carry out a comprehensive review for state-of-the-art works in disruption risk management of express logistics mainly supported by air-transportation. The authors aim to suggest some new research directions and insights for express logistics practitioners to develop more robust planning in air-transportation.
Design/methodology/approach
The authors mainly confined the research to papers published over the last two decades. The search process was conducted in two dimensions: horizontal and vertical. In the horizontal dimension, attention was paid to the evolution of disruption management across the timeline. In the vertical dimension, different foci and strategies of disruption management are employed to distinguish each article. Three keywords were used in the full text query: “Disruption management”, “Air transportation”, and “Airline Operations” in all database searches listed above. Duplications due to database overlap, articles other than those from academic journals, and papers in languages other than English were discarded.
Findings
A total of 98 articles were studied. The authors categorized the papers into two broad categories: Reactive Recovery, and Proactive Planning. In addition, based on the problem characteristics and their application scenarios, a total of 11 sub-categories in reactive recovery and nine sub-categories in proactive planning were further identified. From the analysis, the authors identified some new categories in the air-transportation recovery. In addition, by analyzing the papers in robust planning, according to the problem characteristics and the state-of-the-art research in recovery problems, the authors proposed four new research directions to enhance the reliability and robustness of air-transportation express logistics.
Research limitations/implications
This study provided a comprehensive and feasible taxonomy of disruption risk management. The classification scheme was based on the problem characteristics and the application scenarios, rather than the algorithms. One advantage of this scheme is that it enables an in-depth classification of the problem, that is, sub-categories of each class can be revealed, which provides a much wider and clearer horizon to the scientific progress in this area. This helps researchers to reveal the problem’s nature and to identify the future directions more systematically. The suggestions for future research directions also point out some critical research gaps and opportunities.
Practical implications
This study summarized various reasons which account for the disruption in air-transportation. In addition, the authors suggested various considerations for express logistics practitioners to enhance logistics network reliability and efficiency.
Originality/value
There are various classification schemes in the literature to categorize disruption management. Using different algorithms (e.g. exact algorithm, heuristics, meta-heuristics) and distinct characteristics of the problem elements (e.g. aircraft, crew, passengers, etc.) are the most common schemes in previous efforts to produce a disruption management classification scheme. However, the authors herein attempted to focus on the problem nature and the application perspective of disruption management. The classification scheme is hence novel and significant.

Abstract
Purpose
The purpose of this paper is to present and analyze the effect of applied load and sliding velocity on the tribological behaviors of aramid fiber (AF) reinforced PA1010 which can be a potential material for transmission components.
Design/methodology/approach
The PA1010 composites with different content of AF are prepared and the tribology experiments are conducted on a block‐on‐ring wear tester under different experiment conditions. The wear mechanism of the composite is examined by means of scanning electron microscopy.
Findings
The addition of AF decreased the friction coefficient of PA1010 and increased its wear resistance. For optimal tribological properties 5∼15 wt% AF is preferred, while the wear resistance is best at 15 wt%. The friction coefficient decreased with increasing load and sliding velocity, but it is more sensitive to load. The main wear mechanism is abrasive wear at relatively low load and sliding velocity. With the increasing of load, the adhesive wear occurs in the matrix, meanwhile obvious fibrillation and layer peeling are observed on the fiber. When the sliding velocity increases, thermal adhesion and fiber debonding is the dominant mechanism.
Practical implications
PA1010 is a useful material for the alternative material of transmission components in industry.
Originality/value
PA1010 composite is prepared with a new kind of AF fiber and the tribology experiments have been carried out emphasizing on the variation of experiment conditions. The results could be useful for the material engineers.

Abstract
Purpose
Electrical capacitance tomography (ECT) and electrical resistance tomography (ERT) are promising techniques for multiphase flow measurement due to their high speed, low cost, non-invasive and visualization features. There are two major difficulties in image reconstruction for ECT and ERT: the “soft-field”effect, and the ill-posedness of the inverse problem, which includes two problems: under-determined problem and the solution is not stable, i.e. is very sensitive to measurement errors and noise. This paper aims to summarize and evaluate various reconstruction algorithms which have been studied and developed in the word for many years and to provide reference for further research and application.
Design/methodology/approach
In the past 10 years, various image reconstruction algorithms have been developed to deal with these problems, including in the field of industrial multi-phase flow measurement and biological medical diagnosis.
Findings
This paper reviews existing image reconstruction algorithms and the new algorithms proposed by the authors for electrical capacitance tomography and electrical resistance tomography in multi-phase flow measurement and biological medical diagnosis.
Originality/value
The authors systematically summarize and evaluate various reconstruction algorithms which have been studied and developed in the word for many years and to provide valuable reference for practical applications.
