This book analyzes potential yields of six major food crops - rice, wheat, maize, potato, soybean and rapeseed worldwide using both qualitative and quantitative approaches to study both China’s and global food security under climate change. Firstly, it reviews previous studies on potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide to provide a detailed information of studying on China’s and global food security based on the product’s supply and demand of these crops. Secondly, average and top (national) yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 on global scale are employed to analyze their temporal and spatial variation trends and potential limits. Thirdly, the effects of global warming in climate change on both average and top yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 at global level are analyzed using regression model, and their differences between average and top yields among these crops are identified and compared. Fourthly, the yields and per capita quantity of rice, wheat, maize, potato, soybean and rapeseed in major producer-countries and the world are analyzed to assess the situation and trend of international trade for the products of these crops, respectively. Fifthly, potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide by 2030 are projected using both trend-regressed models and ARIMA models to estimate the per capita quantity of these crops based on the projection of world population and assess the status of Chinese and global food security in that future. Finally, it provides policy implications and advice on food security for China and the world directing food production by 2030 under climate change.
The book comprises ten chapters, Each chapter contains serveral soved problems clarifying the introduced concepts. Some of the examples are taken from the recent literature and serve to illustrate the applications in various fields of engineering and science. At the end of each chapter, there are assignment problems with two levels of difficulty. A list of references is provided at the end of the book. This book is the product of a close collaboration between two mathematicians and an engineer. The engineer has been helpful in pinpointing the problems which engineering students encounter in books written by mathematicians. Contents: Review of Calculus and Ordinary Differential Equations; Series Solutions and Special Functions; Complex Variables; Vector and Tensor Analysis; Partial Differential Equations I; Partial Differential Equations II; Numerical Methods; Numerical Solution of Partial Differential Equations; Calculus of Variations; Special Topics. Readership: Upper level undergraduates, graduate students and researchers in mathematical modeling, mathematical physics and numerical &computational mathematics.
This up-close look at Chinese ESL teachers documents undertakings at formal and informal levels to support and sustain their expertise in ways that balance collaborative and competitive efforts, situated and standards-based programs, ethnically responsive and government-based efforts, and traditional and 21st-century teaching visions. English is a mandated subject for approximately 400 million Chinese public school students. Making transparent the training and professional development received respectively by pre-service and in-service teachers, this book provides a rare window into how Chinese English Language teachers (ELTs) reconcile the two needs with the responsibility to teach large numbers of students while also navigating societal, cultural, and institutional cross currents. It also explores the range of ways China invests in the training and professional development of its English language teachers.
This book describes through case studies how various factors, such as the single-party political system, traditional culture, market reform, and industrialization, shape public opinion and mass political behavior in urban China. Case studies focus on the process of conducting public opinion polls in China’s political environment, regime legitimacy and reform support, media control and censorship, interpersonal trust and democratization, mass political participation, labor relations and trade unions, and the role of intellectuals in political change. The book draws most of its empirical evidence from twelve Chinese public opinion surveys conducted between the late 1980s and the late 1990s. The same questions repeated in many of these surveys provide a rare opportunity to examine the changing pattern of the Chinese public mind during this period. The book ends with the provocative conclusion that China’s authoritarian political system proved to be less effective than traditional culture, marketization, and industrialization in shaping public opinion and mass political behavior. Liberal ideas and bottom-up political participation can emerge even in the absence of direct elections.
This book studies the coordination mechanism of labor relations from the perspective of China’s law on employer association. The first part of the book examines the definition, functions, and institutional basis of employer associations in different types of labor relations, focusing on the complementarity between the law and the coordination mechanism of labor relations in the context of different social environments, institutional frameworks, and their different responses to deregulated labor policies. It then reviews the legislation, responsibilities, and institutional guarantees of employer associations in modern China. The second part outlines the current limitations of legal resources in terms of subject matter, participation mechanisms, and participation channels that constrain the coordination of industrial relations by China’s employer associations. The author emphasizes that the systematic legal safeguards of employer associations should be function-oriented and gradually established in a targeted and differentiated manner. The title will appeal to labor and employment law scholars and legislators, and especially to those interested in the law of employer association.
