This book makes both empirical and conceptual contributions to the debate on privatization of higher education in China. Empirically, it aims to fill a gap in our knowledge of privatization of higher education in North China. To this end, Beijing was chosen as a case for analysis, and nine local higher educational institutions were visited. The case study strategy is also complemented by an extensive review of national policies to reveal problems beyond the specific case of Beijing and of national concern. The effects of the cultural and socioeconomic background and the unique state-party controlling system on higher education management are stressed. Conceptually, most existing studies on privatization of higher education in China adopt a policy analysis approach, while research on privatization of other public sectors or in other countries is frequently guided by economic theories. This book thus seeks to combine both social policy and econometric approaches to provide a systematic and detailed investigation of the privatization process in the context of higher education. It also improves examines the applicability of western theories in the Chinese context.

As the second volume of a two-volume set on the history of Chinese phonology, this book studies the history of phonology from the Yuan dynasty until modern times and discusses the four approaches of sound change. Based on abundant phonological materials, the author divides the history of Chinese phonology into nine historical periods, which helps illuminate its evolutions and principles. Following on from the first volume, the first part of this second volume deals with the initials, rhymes, and tones of Chinese phonology from the Yuan dynasty (1279–1368) to modern times (since 1911), illustrating the diachronic sound changes with detailed tables. Based on an historical review of Chinese phonology, the second part of the book classifies sound changes via four major approaches: no change, gradual shift, split, and merger. It then analyzes the natural, conditional, and irregular sound changes, respectively, and the reasons for these changes. This title will be of great value for scholars and students studying Chinese phonology and Chinese linguistics, and readers interested in the essence of rhyming behind Chinese classic lyrics, poetry, drama, and other forms of verse.

Although sensor fusion is an essential prerequisite for autonomous driving, it entails a number of challenges and potential risks. For example, the commonly used deep fusion networks are lacking in interpretability and robustness. To address these fundamental issues, this book introduces the mechanism of deep fusion models from the perspective of uncertainty and models the initial risks in order to create a robust fusion architecture. This book reviews the multi-sensor data fusion methods applied in autonomous driving, and the main body is divided into three parts: Basic, Method, and Advance. Starting from the mechanism of data fusion, it comprehensively reviews the development of automatic perception technology and data fusion technology, and gives a comprehensive overview of various perception tasks based on multimodal data fusion. The book then proposes a series of innovative algorithms for various autonomous driving perception tasks, to effectively improve the accuracy and robustness of autonomous driving-related tasks, and provide ideas for solving the challenges in multi-sensor fusion methods. Furthermore, to transition from technical research to intelligent connected collaboration applications, it proposes a series of exploratory contents such as practical fusion datasets, vehicle-road collaboration, and fusion mechanisms. In contrast to the existing literature on data fusion and autonomous driving, this book focuses more on the deep fusion method for perception-related tasks, emphasizes the theoretical explanation of the fusion method, and fully considers the relevant scenarios in engineering practice. Helping readers acquire an in-depth understanding of fusion methods and theories in autonomous driving, it can be used as a textbook for graduate students and scholars in related fields or as a reference guide for engineers who wish to apply deep fusion methods.

The book focuses on issues on bilateral relations between the EU and China and evaluation on the impact of China's tariff changes on the two economies with a CGE model. Through analyzing the statistic data and relevant document, we find that for the EU, China seems to be the most important partner in Asia and predominant interests of Europe in China are in the domains of economics and politics. Economic relations are thought to be far more important for both the EU and China than other sensitive issues such as human rights. Meanwhile, using a CGE model, we find that China's tariff reduction seems to impact the Chinese economy stronger than the European economy, and China's textile and apparel industries are the biggest winners whereas the motor vehicle and parts industry is the biggest losers with China's trade liberalization.
