This book constitutes the proceedings of the Second International Conference on 5G for Future Wireless Networks, 5GWN 2019, held in Changsa, China, in February 2019.

This book constitutes the proceedings of the Third International Conference on 6G for Future Wireless Networks, 6GN 2020, held in Tianjin, China, in August 2020. The 45 full papers were selected from 109 submissions and present the state of the art and practical applications of 6G technologies.

This book describes the algorithms, validation and preliminary analysis of the Global LAnd Surface Satellite (GLASS) products, a long-term, high-quality dataset that is now freely available worldwide to government organizations and agencies, scientific research institutions, students and members of the general public.The GLASS products include leaf area index, broadband albedo, broadband emissivity, downward shortwave radiation and photosynthetically active radiation. The first three GLASS products cover 1981 to 2012 with 1km and 5km spatial resolutions and 8-day temporal resolution, and the last two GLASS products span 2008 to 2010 with 3-hour temporal resolution and 5km spatial resolution. These GLASS products are unique. The first three are spatially continuous and cover the longest period of time among all current similar satellite products. The other two products are the highest spatial-resolution global radiation products from satellite observations that are currently available.These products can be downloaded from Beijing Normal University at http://glass-product.bnu.edu.cn/ and the University of Maryland Global Land Cover Facility at http://www.glcf.umd.edu/The GLASS products are the outcome of a key research project entitled “Generation & Applications of Global Products of Essential Land Variables”, supported by funding from the High-Tech Research and Development Program of China and involving dozens of institutions and nearly one hundred scientists and researchers.Following an introduction, the book contains five chapters corresponding to these five GLASS products: background, algorithm, quality control and validation, preliminary analysis and applications. It discusses the long-term environmental changes detected from the GLASS products and other data sources at both global and local scales and also provides detailed analysis of regional hotspots where environmental changes are mainly associated with climatechange, drought, land-atmosphere interactions, and human activities.The book is based primarily on a set of published journal papers about these five GLASS products and includes updated information. Since these products have now begun to be widely used, this book is an essential reference document. It is also a very helpful resource to anyone interested in satellite remote sensing and its applications.

This book takes an in-depth look at the development of the private education sector in modern China. Readers will find valuable data and materials never before presented in such an accessible and transparent way, together with analyses of the major changes and challenges in the course of this development. The book is organized both chronologically and by topic: it employs a past-present-future order that unites the general arrangement; at the same time, each specific subject is approached historically, not only to show the origins of the problem, but also to link it with the historical-comparative context, in which the evaluation of alternative policy choices become highly viable.Further, the book provides a pioneering account of current problems, adopting a fresh perspective to address the most important aspects of Chinese private education reform. The elaboration on topics concerning private school assets, property rights, legal personality, school operators’ entrepreneurship, benefits and investment returns, school autonomy, and the development of teachers and students, is both empirically rich and highly insightful.The book’s content is chiefly derived from years of fieldwork in private schools and from extensive interviews with hundreds of policy makers, school operators, managers, teachers and students. Since these people are self-conscious about themselves as the actors in and witnesses to the development of Chinese private education over the past three decades, the book places great emphasis on neutrality, allowing the private education landscape to unfold in the context of the privatization of the socialist system after 1978. The book offers an essential guide for anyone who wishes to understand the transformation of Chinese education. It is highly recommendable as a detailed introduction to Chinese education, or as a resource for comparative research on private education from an international perspective.

This book presents two collaborative prediction approaches based on contextual representation and hierarchical representation, and their applications including context-aware recommendation, latent collaborative retrieval and click-through rate prediction. The proposed techniques offer significant improvements over current methods, the key determinants being the incorporated contextual representation and hierarchical representation. To provide a background to the core ideas presented, it offers an overview of contextual modeling and the theory of contextual representation and hierarchical representation, which are constructed for the joint interaction of entities and contextual information.The book offers a rich blend of theory and practice, making it a valuable resource for students, researchers and practitioners who need to construct systems of information retrieval, data mining and recommendation systems with contextual information.

This book gathers selected original papers presented at the Sixth Beijing Normal University - University College London, Institute of Education International Conference in Education, a biennial event organised in partnership between this two universities.

This book introduces readers to the status quo and recent advances in China’s low-carbon development. From the evolution of human civilization, to the proposal of low-carbon concepts, up to the choice of China’s low-carbon path, the book provides a comprehensive review of low-carbon development, while also elaborating on the core concept, goals and methods. In addition, it addresses a series of questions and issues closely tied to today’s social development, such as: “Why is it so vital to pursue low-carbon development?” and “How can China implement low-carbon development?” Accordingly, readers will gain a better grasp of low-carbon development, including low-carbon production and low-carbon lifestyles.
