Rural-urban migration is an important aspect in the development of countries. Until the late 1980s China was one of the few countries that controlled population movement both directly and indirectly through policies of economic and social control. The gradual relaxation of these policies has resulted in greater freedom of movement for the population, the effects of which are discussed in this significant volume. The book concentrates on the migration of minorities from a social, economic and ethnic perspective and attempts to quantify the overall level of movement. In particular, the authors examine the relationships between education, ethnicity and migration and identify the policies and conditions conducive to achieving positive outcomes for minority migrant households. The book aims to increase our understanding of the effects of movement, on the social, economic and ethnic status of migrant families. Taking existing census data as a starting point, the book makes a new contribution by drawing on a unique survey in four different regions, the data from which is used as the basis for detailed case study analysis. The study of internal migration is vital, the authors argue, in order to understand the change process from a centrally planned economic system to a market orientated society in China. The internal mobility of minorities can be regarded equally, as both a product of, and a contributing factor to, this social transformation. This notable and very readable book will be of significant interest to policymakers, international and development economists and researchers and students of Asian economics and demographics.

The authors begin this book with a systematic overview of superconductivity, superconducting materials, magnetic levitation, and superconducting magnetic levitation - the prerequisites to understand the latter part of the book - that forms a solid foundation for further study in High Temperature Superconducting Magnetic Levitation (HTS Maglev). This book presents our research progress on HTS Maglev at Applied Superconductivity Laboratory (ASCLab) of Southwest Jiaotong University (SWJTU), China, with an emphasis on the findings that led to the world's first manned HTS Maglev test vehicle "Century". The book provides a detailed description on our previous work at ASCLab including the designing of the HTS Maglev test and measurement method as well as the apparatus, building "Century", developing the HTS Maglev numerical simulation system, and making new progress on HTS Maglev. The final parts of this book discuss research and prototyping efforts at ASCLab in several adjacent fi elds including HTS Maglev bearing, Flywheel Energy Storage System (FESS) and HTS maglev launch technology. We hope this book becomes a valuable source for researchers and engineers working in the fascinating field of HTS Maglev science and engineering.

North America maintains the largest collection of archival materials relating to the Chinese Republican era (1911-1949) outside of China. Most of the archival materials are also unique, and the collections contain special materials supplementing historical records in China and Taiwan. In many cases, North America's holdings represent the best and only public access to the tumultuous Republican government and society of the first half of the twentieth century. An essential guide for researchers and students of Republican China, this volume, presented in both English and Chinese, covers personal papers, correspondences, memoirs, diaries, photographs, moving images, and other materials held at academic and research institutions across the United States and Canada. It includes concise descriptions of the people, organizations, and events connected to each entry and notes when certain collections are closely related and when materials are digitized for online access. The book corrects common errors associated with the library records of many archives and updates or completes information on the objects of these records. More than a straightforward itemization, this book adds significant depth to any research on the history and global import of China's modern development.
