China's Scientific Elite is a study of those scientists holding China's highest academic honour - membership of the Chinese Academy of Sciences. Having carried out extensive systematic data collection of CAS members Cao examines the social stratification system of the Chinese science community and the way in which politics and political interference has effected the stratification. The book then goes on to compare the Chinese system to the stratification of the US scientific elite. The conclusions are fascinating, not least because one national elite resides in a democratic liberal social system, and the other in an authoritarian social system.
China is emerging as a new superpower in science and technology, reflected in the success of its spacecraft and high-velocity Maglev trains. While many seek to understand the rise of China as a technologically-based power, the Cultural Revolution of the 1960s may seem an unlikely era to explore for these insights. Despite the widespread verdict of the Great Proletarian Cultural Revolution as an unmitigated disaster for China, a number of recent scholars have called for re-examining Maoist science—both in China and in the West. At one time Western observers found much to admire in Chairman Mao's mass science, his egalitarian effort to take science out of the ivory tower and place it in the hands of the disenfranchised peasant, the loyal worker, and the patriot soldier. Chunjuan Nancy Wei and Darryl E. Brock have assembled a rich mix of talents and topics related to the fortunes and misfortunes of science, technology, and medicine in modern China, while tracing its roots to China's other great student revolution—the May Fourth Movement. Historians of science, political scientists, mathematicians, and others analyze how Maoist science served modern China in nationalism, socialism, and nation-building—and also where it failed the nation and the Chinese people. If the Cultural Revolution contributed to China's emerging space program and catalyzed modern malaria treatments based on Traditional Chinese Medicine, it also provided the origins of a science talent gap and the milieu from which a one-child policy would arise. Given the fundamental importance of China today, and of East Asia generally, it is imperative to have a better understanding of its most recent scientific history, but especially that history in a period of crisis and how that crisis was resolved. What is at issue here is not only the specific domain of the history of science, but the social and scientific policies of China generally as they developed and were applied prior to, during, and after the Cultural Revolution.

In China, as elsewhere, the debate over genetically modified organisms has become polarized into anti- and pro-GMO camps. Given the size of China’s population and market, much is at stake in conflicts over regulation for domestic as well as international actors. In this book, Cong Cao provides an even-handed analysis that illuminates the tensions that have shaped China’s policy toward agricultural biotechnology in a global perspective. Cao presents a comprehensive and systematic analysis of how China’s policy toward research and commercialization of genetically modified crops has shifted that explains how China’s changing GMO stances reflect its evolving position on the world stage. While China’s scientific community has set the agenda, it has encountered resistance rooted in concerns over food safety and consumers’ rights as well as issues of intellectual property rights and food sovereignty. Although Chinese leaders at first sought to take advantage of the biotech revolution by promoting GMO crop consumption, Cao demonstrates that policy has since become precautionary, as seen in new laws and regulations grounded in concerns over safety and the deferral of commercialization of GM rice. He presents China’s policies in light of changing global attitudes toward GM crops: As shifts in China have closely followed global trends, so has domestic activism. Drawing on government and scientific documents as well as interviews with scientists, officials, policy analysts, activists, and journalists, GMO China is an important book for China studies, science and technology studies, policy analysts, and professionals interested in the Chinese biotechnology market.
The celebrated lower Cambrian Chengjiang biota of Yunnan Province, China, represents one of the most significant ever paleontological discoveries. Deposits of ancient mudstone, about 520 million years old, have yielded a spectacular variety of exquisitely preserved fossils that record the early diversification of animal life. Since the discovery of the first specimens in 1984, many thousands of fossils have been collected, exceptionally preserving not just the shells and carapaces of the animals, but also their soft tissues in fine detail. This special preservation has produced fossils of rare beauty; they are also of outstanding scientific importance as sources of evidence about the origins of animal groups that have sustained global biodiversity to the present day. Much of the scientific documentation of the Chengjiang biota is in Chinese, and the first edition of this book was the first in English to provide fossil enthusiasts with a comprehensive overview of the fauna. The second edition has been fully updated and includes a new chapter on other exceptionally preserved fossils of Cambrian age, exciting new fossil finds from Chengjiang, and a phylogenetic framework for the biota. Displaying some 250 figures of marvelous specimens, this book presents to professional and amateur paleontologists, and all those fascinated by evolutionary biology, the aesthetic and scientific quality of the Chengjiang fossils.
Xiaoping Cong examines the social and cultural significance of Chinese revolutionary legal practice in the construction of marriage and gender relations. Her book is an empirically rich investigation of the ways in which a 1943 legal dispute over an arranged marriage in a Chinese village became a legal, political and cultural exemplar on the national stage. This conceptually groundbreaking study revisits the Chinese Revolution and its impact on women and society by presenting a Chinese experience that cannot and should not be theorized in the framework of Western discourse. Taking a cultural-historical perspective, Cong shows how the Chinese Revolution and its legal practices produced new discourses, neologisms and cultural symbols that contained China's experience in twentieth-century social movements, and how revolutionary practice was sublimated into the concept of 'self-determination', an idea that bridged local experiences with the tendency of the twentieth-century world, and that is a revolutionary legacy for China today.

During the Song (960-1279), all educated Chinese men traveled frequently, journeying long distances to attend school and take civil service examinations. They crisscrossed the country to assume government posts, report back to the capital, and return home between assignments and to attend to family matters. Based on a wide array of texts, Transformative Journeys analyzes the impact of travel on this group of elite men and the places they visited. In the first part of the book, Cong Ellen Zhang considers the practical aspects of travel during the Song in the context of state mobilization of and assistance to government travelers, including the infrastructure of waterways and highways, the bureaucratic procedures entailed in official travel, and the means of transport and types of lodging. The second part of the book focuses on elite activities on the road, especially the elaborate farewell banquets, welcoming ceremonies, and visits to famous places. Zhang argues convincingly that abundant travel experience became integral to Song elite identity and status, greatly strengthening the social and cultural coherence of the practitioners. In promoting their experience of traveling across a large empire, Song elite men firmly established their position as the country’s political, social, and cultural leaders. The literary compositions and physical traces they left behind also formed an overlapping web of collective memories, continually enhancing local pride and defining the place of various localities in the cultural geography of the country. Transformative Journeys sheds new light on the nature of Chinese literati, their dominance of culture and society, and China’s social and cultural integration. Those interested in premodern China and travel literature will find a wealth of material previously unavailable to Western readers.
Educated men in Song-dynasty China (960–1279) traveled frequently in search of scholarly and bureaucratic success. These extensive periods of physical mobility took them away from their families, homes, and native places for long periods of time, preventing them from fulfilling their most sacred domestic duty: filial piety to their parents. In this deeply grounded work, Ellen Zhang locates the tension between worldly ambition and family duty at the heart of elite social and cultural life. Drawing on more than 2,000 funerary biographies and other official and private writing, Zhang argues that the predicament in which Song literati found themselves diminished neither the importance of filial piety nor the appeal of participating in examinations and government service. On the contrary, the Northern Song witnessed unprecedented literati activity and state involvement in the bolstering of ancient forms of filial performances and the promotion of new ones. The result was the triumph of a new filial ideal: luyang. By labeling highly coveted honors and privileges attainable solely through scholarly and official accomplishments as the most celebrated filial acts, the luyang rhetoric elevated office-holding men to be the most filial of sons. Consequently, the proper performance of filiality became essential to scholar-official identity and self-representation. Zhang convincingly demonstrates that this reconfiguration of elite male filiality transformed filial piety into a status- and gender-based virtue, a change that had wide implications for elite family life and relationships in the Northern Song. The separation of elite men from their parents and homes also made the idea of “native place” increasingly fluid. This development in turn generated an interest in family preservation as filial performance. Individually initiated, kinship- and native place-based projects flourished and coalesced with the moral and cultural visions of leading scholar-intellectuals, providing the social and familial foundations for the ascendancy of Neo-Confucianism as well as new cultural norms that transformed Chinese society in the Song and beyond.
During the educational and social transformations in politically tumultuous early twentieth-century China, Chinese teacher's schools played a critical role. They were a force in the changes that swept Chinese society, bridging Chinese and Western ideals, empowering women, and contributing to rural modernization. This innovative account examines the social and political aspects and impacts of these schools, their role in a society in transistion, and their production of grassroots forces that lead to the Communist Revolution.
This book focuses on ubiquitous indoor localization services, specifically addressing the issue of floor plans. It combines computer vision algorithms and mobile techniques to reconstruct complete and accurate floor plans to provide better location-based services for both humans and vehicles via commodity smartphones in indoor environments (e.g., a multi-layer shopping mall with underground parking structures). After a comprehensive review of scene reconstruction methods, it offers accurate geometric information for each landmark from images and acoustics, and derives the spatial relationships of the landmarks and rough sketches of accessible areas with inertial and WiFi data to reduce computing overheads. It then presents the authors’ recent findings in detail, including the optimization and probabilistic formulations for more solid foundations and better robustness to combat errors, several new approaches to promote the current sporadic availability of indoor location-based services, and a holistic solution for floor plan reconstruction, indoor localization, tracking, and navigation. The novel approaches presented are designed for different types of indoor environments (e.g., shopping malls, office buildings and labs) and different users. A valuable resource for researchers and those in start-ups working in the field, it also provides supplementary material for students with mobile computing and networking backgrounds.
Addresses issues surrounding China's science and technology talent pool, and suggests significant policy implications for China and the international community.
China is in the midst of transitioning from a manufacturing-based economy to one driven by innovation and knowledge. This up-to-date analysis evaluates China's state-led approach to science and technology, and its successes and failures. In recent decades, China has seen huge investments in high-tech science parks, a surge in home-grown top-ranked global companies, and a significant increase in scientific publications and patents. Helped by state policies and a flexible business culture, the country has been able to leapfrog its way to a more globally competitive position. However, the authors argue that this approach might not yield the same level of progress going forward if China does not address serious institutional, organizational, and cultural obstacles. While not impossible, this task may well prove to be more difficult for the Chinese Communist Party than the challenges that China has faced in the past.

Since the end of Dennard scaling in the early 2000s, improving the energy efficiency of computation has been the main concern of the research community and industry. The large energy efficiency gap between general-purpose processors and application-specific integrated circuits (ASICs) motivates the exploration of customizable architectures, where one can adapt the architecture to the workload. In this Synthesis lecture, we present an overview and introduction of the recent developments on energy-efficient customizable architectures, including customizable cores and accelerators, on-chip memory customization, and interconnect optimization. In addition to a discussion of the general techniques and classification of different approaches used in each area, we also highlight and illustrate some of the most successful design examples in each category and discuss their impact on performance and energy efficiency. We hope that this work captures the state-of-the-art research and development on customizable architectures and serves as a useful reference basis for further research, design, and implementation for large-scale deployment in future computing systems.
A Comprehensive Monograph on Dioxirane Oxidations The oxidation of organic compounds is one of the most important methods for the introduction and manipulation of functional groups. Among the most modern of these transformations is the use of the fascinating family of oxidants known as dioxiranes. A dioxirane can, by transferring one of its oxygen atoms to organic substrates, effect a remarkable array of oxidative processes such as epoxidation, C-H insertion, and heteroatom (N, S, P, I) oxidation. In addition to their versatility, dioxiranes can be generated catalytically under mild conditions and produce no toxic waste stream as part of the oxidation process. Moreover, some of the most exciting recent developments involve the enantioselective introduction of oxygen atoms via chiral dioxiranes. This book represents the first single volume dedicated to the comprehensive coverage of the myriad of oxidations of organic compounds performed by dioxiranes. The contents of this book are extracted from comprehensive reviews of the topics contained in the Organic Reactions series and cover the oxidation of alkenes and the oxidation of all other organic substrates. In addition, updated lists of references for each of the chapters are provided, bringing the literature coverage up to June 2008. The authors of these chapters are among the pioneers of dioxirane chemistry and draw on extensive firsthand knowledge of the subject. As with all Organic Reactions content, the presentation emphasizes the preparative aspects of the reactions and pays particular attention throughout to substrate scope, limitations, structural and electronic influences, and stereochemical aspects. For the student or experienced practitioner, both general guidelines for carrying out the reactions as well as detailed experimental procedures are provided. Most importantly, all known examples of dioxirane oxidations have been compiled in easy-to-scan tables covering over 500 pages. Oxidation of Organic Compounds by Dioxiranes is an indispensable working resource for organic and medicinal chemists as well as anyone wishing to own the definitive treatise on this fascinating and useful class of oxidants.
