The purpose of this paper is to establish an accurate model to quantify the effect of conductor roughness on insertion loss (IL) and provide improved measurements and suggestions for manufacturing good conductive copper lines of printed circuit board.

To practically investigates the modified model of conductor roughness, three different kinds of alternate oxidation treatments were used to provide transmission lines with different roughness. The IL results were measured by a vector net analyzer for comparisons with the modified model results.

An accurate model, with only a 1.8% deviation on average from the measured values, is established. Compared with other models, the modified model is more reliable in industrial manufacturing.

This paper introduces the influence of tiny roughness structures on IL. Besides, this paper discusses the effect of current distribution on IL.

China is now deeply involved in the process of globalization. It confronts conflicts, such as traditions versus modernization, internationalization versus localization, and Chinese values versus. universal values. China is more open to the outside world than ever. The authors’ survey of the Journal of International and Comparative Education Research reveals that Chinese comparative educators are turning the focus of their studies to try new paradigms in the context of globalization.

Comparative and international education (CIE) has developed very quickly in China. The first “Academic Conference on Education in Other Countries” was held in China in 1978. The National Society of Foreign Education Studies, the predecessor of the National Comparative Education Society, was formed in 1979. In 1980, Beijing Normal University published the first journal on comparative education in China. Afterwards East China Normal University and Northeast Normal University published their journals on comparative education. The first master and doctoral degree programs in comparative education were offered in China respectively in 1979 and 1985. There are hundreds of scholars engaged in comparative education studies now. In summary, comparative education in China has been turned into a fully-fledged academic discipline with a complete framework. What is more important maybe is that Chinese scholars have been exploring the definitions, functions, culture, and research paradigms of the discipline.

This chapter examines the development of a quality assurance system for undergraduate education as one aspect of the transformation of education policy in China. The central structure of the chapter is the process/stages of policy development and implementation, with particular attention to the changes over time in central control versus institutional autonomy. The Chinese government has moved to a “steering at a distance” approach with ex post accountability, giving institutions of higher education greater autonomy for undergraduate education. Government authority continues to be strong, however, even though the mechanisms of control have changed. This study provides an analysis of quality assurance in Chinese higher education and the changing relationship between government and campuses, using the lens of policy development and implementation.

Tingting Qi's chapter titled, “Moving toward Decentralization? Changing Education Governance in China After 1985,” provides the historical and policy context for the volume. This chapter integrates the post-1978 Chinese educational reforms into the socioeconomic context of China. The special contribution of this chapter is that it explores the complexity of educational decentralization in China through an in-depth analysis of changes in education finance, administration, and curriculum. Qi reviews prior studies, government documents, laws, and regulations related to Chinese education reform since 1978 within the context of education decentralization in China. Qi also demonstrates that China's educational policy reforms are moving China toward “centralized decentralization” because decentralization is driven by a common, centralized national goal of economic modernization. The chapter presents evidence that “centralized decentralization” is a strategic maneuver that maintains centralized control while providing the reform legitimacy of decentralization. By focusing on decentralization as the core of Chinese educational policy reforms, this chapter situates the following chapters within the social, cultural, and political context of post-1978 China.

This paper aims to report a comprehensive analysis of literature on stakeholder relationships towards identifying patterns of relationships within the off-site construction context.

Key scholarly databases were accessed and after a filtering process, 74 relevant papers were retrieved for analysis. The papers were analysed using qualitative content analysis and scientometric techniques through the application of software Leximancer and VOSviewer.

Research synthesis methods used in the present study generate compatible results. Through text mining analysis, the key themes identified in the off-site construction stakeholder relationships literature included “collaboration”, “building information modelling”, “social network analysis”, supply chain. As a finding by scientometric analysis, collaboration, BIM, supply chain management, housing and social network analysis were the most frequently entered keywords context of off-site construction. Regarding authorship pattern, the whole network of collaboration was fragmented into multiple isolated clusters, implying that the authors had tendency to cooperate in small groups.

The paper can bring together an important area of research not previously studied in detail. It will primarily assist academics in the first instance; however, the research leads to important findings that will ultimately assist policymakers and practitioners better understand factors affecting stakeholder relationships and in particular network thinking and collaborative mind-sets.

The review contributes a needed systematic and theoretical foundation for future stakeholder relationship studies and practices in off-site construction sector. It provides the basis for future studies and is a seminal analysis of stakeholder management and off-site construction. The scientometric methodology offers scholars a different approach to analysing and visualising literature reviews.
