Abstract

Purpose

This study aims to the preparation and tribological characteristics of graphene/triangular copper nanoplate composites (abbreviated as GN/Cu nanoplates) as grease additive and clarifies the growth mechanism and tribological mechanism of GN/Cu nanoplates by different analysis methods. In this paper, it is expected to alleviate the problems of easy aggregation and poor dispersion stability of graphene in lubricants and provide theoretical support for the application of graphene and its composites in the tribology field.

Design/methodology/approach

In this study, the GN/Cu nanoplates have been successfully prepared by the electrostatic self-assembly method. The structural characteristics of GN/Cu nanoplates were analyzed via transmission electron microscopy and X-ray diffraction. Then the tribological properties of GN/Cu nanoplates were investigated under different loads with SRV-IV [Schwingung, Reibung, Verschleiß (German); oscillating, friction, wear (English translation)] tribotester. White-light interferometry was applied to quantify the wear loss of the disk. The element chemical state on worn surfaces was analyzed by an X-ray photoelectron spectroscope to clarify the tribological mechanism of graphene composites.

Findings

The electrostatic force between the negative charge of graphene and the positive charge of triangular copper nanoplates promotes the self-assembly of GN/Cu nanoplates. With the addition of GN/Cu nanoplates, the wear loss and average friction coefficient under the load of 200 N have been decreased by 72.6% and 18.3%, respectively. It is concluded that the combined action of graphene deposition film and the copper melting film formed on the worn surface could effectively improve the antiwear ability and friction reduction performance of the grease.

Originality/value

This manuscript fulfills a new approach for the preparation of GN/Cu nanoplates. At the same time, its tribological properties and mechanism as a lubricating additive were studied which provide theoretical support for the application of graphene and its composites in the tribology field.

Abstract

Purpose

This paper seeks to propose that practical wisdom originating within the Chinese classical traditions has been instrumental in China's ascendance to the world stage. Its purpose is to analyze biographical data across 200 Chinese business leaders in order to gauge the relative influence of two competing ideologies – Maoism and Confucianism.

Design/methodology/approach

This paper is based on a two‐step design process. First, modern day leadership archetypes characterizing Maoist and Confucian ideology were developed from the literature. Second, these archetypes were applied in the content analysis of biographical data on Chinese business leaders.

Findings

There was evidence of both Maoism and Confucianism in the practices of Chinese business leaders. An unintended, third cohort of leaders emerged, representative of the younger end of the biographical distribution, who appear to embrace paradox in their ideological orientation.

Practical implications

There were three practical implications for management and leadership development: the importance of integrating the concept of paradox into management and leadership development curricula; the provision of illustrative alternatives to western world leadership exemplars; and increased emphasis on global leadership as an emergent phenomenon with particular attention to the burgeoning internationalization of Chinese enterprise and its associated ideologies.

Originality/value

The current leadership literature is dominated by western world exemplars. This paper offers an alternative view; one rich with the wisdom and classical traditions of the Chinese culture.

Abstract

China has showed its eagerness in using its economic strength in the very recent years. Is China going to be a major sanctioning state like the United States or the European Union? This chapter argues that although there have been an increasing number of economic sanctions imposed by China with its expanding national interests and growing diplomatic problems, China will still keep a low profile in using economic sanctions because of the restraining factors such as the WTO rules, inherent problems in its economy, the pursuit of a good reputation and its strategy of peaceful development. Thus the frequency and tactics of using economic sanctions may vary according to its rising economy and changing international situation, but that will go in a very limited way.

Abstract

Purpose

The purpose of this paper is to provide a conceptual framework of staged development that examines strategies of domestic companies, government policies, and impacts of foreign multinational companies (MNCs) at different periods of catch‐up of latecomers.

Design/methodology/approach

A multi‐case approach is employed to examine four domestic telecom‐equipment companies that have significant impact on China's telecom‐equipment industry. They are: Huawei Technology Corporation (Huawei), Shenzhen Zhongxin Technology Corporation (ZTE), Datang Telecom Technology Corporation, Ltd (Datang), and Great Dragon Information Technology (GDT).

Findings

This paper identifies four distinct stages of the catching‐up process, featuring different institutional environment, government involvement, and the ensuing actions of foreign MNCs and domestic companies. During the initial stage, China's government decision of directly leapfrogging to the most advanced switch equipment had a profound impact, because it led to both heavy reliance on foreign MNCs and the pursuance of switch research and development (R&D) by domestic research institutes and new technology companies. The dominance of foreign MNCs is challenged during the growth stage, because several domestic companies ascended and gained the capability to produce large‐scale, stored program controls and the government directly leveraged support in R&D, marketing, and finance. Although many uncompetitive domestic companies failed during the filtration stage, the management training received from foreign MNCs and newly available financing options provided necessary resources for some domestic companies to survive and expand. Domestic leaders globalized their marketing, production, and R&D functions and to become MNCs themselves in the globalization stage, thus finalizing the catching‐up.

Social implications

The Chinese experiences shed light on late‐industrialization for other developing economies by suggesting that to catch‐up in high‐tech industries, government can become involved strategically to form a competitive and efficient market environment for innovation.

Originality/value

The paper proposes a new conceptual framework to analyze catching‐up of domestic companies as latecomers. This framework can be used to study catching‐up in other sectors in late‐industrializing countries.

Abstract

Textbook content and curricula are artifacts that can serve as indicators of social contexts and societal values. In this chapter, we use qualitative and quantitative content analysis to examine the content of Chinese language arts textbooks for basic education during a period of curriculum reform in China at the start of the 21st century. Given the important role of the Chinese language arts in the socialization of students into official societal values, this study seeks to provide insight into the nature of the official world view in China and addresses the societal ambivalence between global vs. national/local and traditional knowledge vs. Western/contemporary knowledge. We find that there is a slight increase in themes that reflect contemporary global concerns such as creativity and social justice. We also find that, in the face of the globalizing cultural influences of the new millennium, there is a sustained emphasis on the role of the Chinese language curriculum in the transmission of traditional Chinese cultural values and on the cultivation in Chinese students of an appreciation of their rich cultural traditions.
