Between the 1980s and the present day, China has experienced one of the most consequential economic transformations in world history. One-fifth of the Earth's population has left behind a life of scarcity and subsistence for one of abundance and material comfort, while their nation has emerged as a preeminent economic and political power. In a systematic historical and sociological analysis of this unique juncture, Wang Feng charts the origins, forces, and consequences of this meteoric rise in living standards. He shifts the focus away from institutions and policies to offer new perspectives based on consumption among poorer, rural populations as a driver of global economic change. But is this 'Age of Abundance' coming to an end? Anticipating potential headwinds, including an aging population, increasing inequality, and intensifying political control, Wang explores whether this preeminence could be coming to a close.

The book lies at the interface of mathematics, social media analysis, and data science. Its authors aim to introduce a new dynamic modeling approach to the use of partial differential equations for describing information diffusion over online social networks. The eigenvalues and eigenvectors of the Laplacian matrix for the underlying social network are used to find communities (clusters) of online users. Once these clusters are embedded in a Euclidean space, the mathematical models, which are reaction-diffusion equations, are developed based on intuitive social distances between clusters within the Euclidean space. The models are validated with data from major social media such as Twitter. In addition, mathematical analysis of these models is applied, revealing insights into information flow on social media. Two applications with geocoded Twitter data are included in the book: one describing the social movement in Twitter during the Egyptian revolution in 2011 and another predicting influenza prevalence. The new approach advocates a paradigm shift for modeling information diffusion in online social networks and lays the theoretical groundwork for many spatio-temporal modeling problems in the big-data era.

Illegality in Marine Insurance Law is the first book to deal specifically with illegality in the context of marine insurance law. Previously, this issue has only ever been partially covered within analysis and criticism of Section 41 of the Marine Insurance Act 1906 and warranties. However, Dr Wang Feng goes much further than this by considering its impact on the common law relevant to marine insurance in many jurisdictions worldwide. The book addresses whether the existing law represents an accurate codification of the former authorities and whether Section 41 truly reflects existing legal principles. As well as this, the book examines how correctly to approach illegality within the context of marine insurance, considering the fundamental changes to the rule of breach of warranty introduced by the Insurance Act 2015. Of interest to academic researchers and practitioners in common law and civil law jurisdictions, this book provides rigorous analysis of the illegality issue and a conceptual approach for various approaches to reform marine insurance law. It is a unique and comprehensive guide to illegality in marine insurance law.

This book examines the trends, underlying factors, and policy implications of fertility declines in three East Asian countries: Japan, South Korea, and China. In contrast to Western countries that have also experienced fertility declines to below-replacement levels, fertility decline in these East Asian countries is most notable in its rapidity and sheer magnitude. After a rapid decline shortly after the war, in which fertility was halved in one decade from 4.5 children per woman in 1947 to 2.1 in 1957, Japan's fertility started to decline to below-replacement levels in the mid-1970s, reaching 1.3 per woman in the early 2000s. Korea experienced one of the most spectacular declines ever recorded, with fertility falling continuously from very high (6.0 per woman) to a below-replacement level (1.6 per woman) between the early 1960s and mid-1980s, reaching 1.1 per woman in 2005. Similarly, after a dramatic decline from very high to low levels in one decade from the early 1970s to early 1980s, China's fertility reached around 1.5 per woman by 2005. Despite differences in timing, tempo, and scale of fertility declines, dramatic fertility reductions have resulted in extremely rapid population aging and foreshadow a long-term population decline in all three countries. This monograph provides a systematic comparison of fertility transitions in these East Asian countries and discusses the economic, social, and cultural factors that may account for their similarities and differences. After an overview of cultural backgrounds, economic transformations, and the evolution of policies, the trends and age patterns of fertility are examined. The authors then investigate changes in women's marriage and childbearing within marriage, the two major direct determinants of fertility, followed by an analysis of the social and economic factors underlying fertility and nuptiality changes, such as education, women's employment, and gender relations at home.

Oversampled A/D converters have become very popular in recent years. Some of their advantages include relaxed requirements for anti-alias filters, relaxed requirements for component matching, high resolution and compatibility with digital VLSI technology. There is a significant amount of literature discussing the principle, theory and implementation of various oversampled converters. Such converters are likely to continue to proliferate in the foreseeable future. Additionally, more recently there has been great interest in low voltage and low power circuit design. New design techniques have been proposed for both the digital domain and the analog domain. Both trends point to the importance of the low-power design of oversampled A/D converters. Unfortunately, there has been no systematic study of the optimal design of modulators for oversampled converters. Design has generally focused on new architectures with little attention being paid to optimization. The goal of Design of Modulators for Oversampled Converters is to develop a methodology for the optimal design of modulators in oversampled converters. The primary focus of the presentation is on minimizing power consumption and understanding and limiting the nonlinearities that result in such converters. Design of Modulators for Oversampled Converters offers a quantitative justification for the various design tradeoffs and serves as a guide for designing low-power highly linear oversampled converters. Design of Modulators for Oversampled Converters will serve as a valuable guide for circuit design practitioners, university researchers and graduate students who are interested in this fast-moving area.

In the last two decades of the twentieth century, following the worldwide collapse of communism, China ascended from being one of the most egalitarian societies in the world to one of the more unequal. Wang Feng documents the process of rising inequality in urban China during this period, and explores the underlying structural forces that define China's emerging social landscape. By treating social categories created under socialism, such as cities and work organizations, as explicit forces generating inequality, the author reveals a pattern that embodies both enlarging inequality between social categories and persistent equality within them. This pattern is traced to China's post-socialist political economy and to a long-existing cultural tradition that places a premium on harmony and group solidarity. China's great reversal from equality to inequality is a powerful example of how social categories, not individual traits and preferences, structure and maintain inequality.
