In the mid-eleventh century BCE, the Zhou overthrew the Shang, a dynastic power that had dominated much of northern and central China. Over the next three centuries, they would extend the borders of their political control significantly beyond those of the Shang. The Zhou introduced a political ideology centered on the Mandate of Heaven to justify their victory over the Shang and their territorial expansion, portraying the Zhou king as ruling the frontier from the center of civilization. Present-day scholarship often still adheres to this core-periphery perspective, emphasizing cultural assimilation and political integration during Zhou rule. However, recent archaeological findings present a more complex picture. Many Worlds Under One Heaven analyzes a wide range of newly excavated materials to offer a new perspective on political and cultural change under the Western Zhou. Examining tombs, bronze inscriptions, and other artifacts, Yan Sun challenges the Zhou-centered view with a frontier-focused perspective that highlights the roles of multiple actors. She reveals the complexity of identity construction and power relations in the northern frontiers of the Western Zhou, arguing that the border regions should be seen as a land of negotiation that witnessed cultural hybridization and experimentation. Rethinking a critical period for the formation of Chinese civilization, Many Worlds Under One Heaven unsettles the core-periphery model to reveal the diversity and flexibility of identity in early China.

This book aims to fill a growing need in the research community for a reference that describes the state-of-the-art in securing group communications. It focuses on tailoring the security solution to the underlying network architecture (such as the wireless cellular network or the ad hoc/sensor network), or to the application using the security methods (such as multimedia multicasts).

Argues that a new set of transnational social welfare arrangements has emerged that challenge traditional social welfare provision based on national citizenship and residence. The idea that social rights are something we are eligible for based on where we live or where we are citizens is out-of-date. In Transnational Social Protection, Peggy Levitt, Erica Dobbs, Ken Chih-Yan Sun, and Ruxandra Paul consider what happens to social welfare when more and more people live, work, study, and retire outside their countries of citizenship where they receive health, education, and elder care. The authors use the concept of resource environment to show how migrants and their families piece together packages of protections from multiple sources in multiple settings and the ways that these vary by place and time. They further show how a new, hybrid transnational social protection regime has emerged in response to the changing environment that complements, supplements, or, in some cases, substitutes for national social welfare systems as we knew them. Examining how national social welfare is affected when migration and mobility become an integral part of everyday life, this book moves our understanding of social protection from the national to the transnational.

Group-oriented communications will play a significant role in the next generation of networks as many services, such as pay-per-view media broadcasts and the delivery of network control messages, will rely upon the ability to reliably deliver data simultaneously to a large group of users. As these networks become increasingly pervasive and these multi-user services become increasingly ubiquitous, it will become essential that a complementary suite of security solutions are deployed in order to protect these services from a broad spectrum of security threats that are unique to group communications.

Many scholars perceive ethnic politics in China as an untouchable topic due to lack of data and contentious, even prohibitive, politics. This book fills a gap in the literature, offering a historical-political perspective on China's contemporary ethnic conflict. Yan Sun accumulates research via field trips, local reports, and policy debates to reveal rare knowledge and findings. Her long-time causal chain of explanation reveals the roots of China's contemporary ethnic strife in the centralizing and ethnicizing strategies of its incomplete transition to a nation state-strategies that depart sharply from its historical patterns of diverse and indirect rule. This departure created the institutional dynamics for politicized identities and ethnic mobilization, particularly in the outer regions of Tibet and Xinjiang. In the 21st century, such factors as the demise of socialist tenets and institutions that upheld interethnic solidarity, and the rise of identity politics and developmentalism, have intensified these built-in tensions.

A momentous debate has been unfolding in China over the last fifteen years, only intermittently in public view, concerning the merits of socialism as a philosophy of social justice and as a program for national development. Just as Deng Xiaoping's better advertised experiment with market- based reforms has challenged Marxist-Leninist dogma on economic policy, the years since the death of Mao Zedong have seen a profound reexamination of a more basic question: to what extent are the root problems of the system due to Chinese socialism and Marxism generally? Here Yan Sun gathers a remarkable group of primary materials, drawn from an unusual range of sources, to present the most systematic and comprehensive study of post-Mao reappraisal of China's socialist theory and practice.

Rejecting an assumption often made in the West, that Chinese socialist thought has little bearing on politics and policymaking, Sun takes the arguments of the post-Mao era seriously on their own terms. She identifies the major factions in the debate, reveals the interplay among official and unofficial forces, and charts the development of the debate from an initially parochial concern with problems raised by Chinese practice to a grand critique of the theory of socialism itself. She concludes with an enlightening comparison of the reassessments undertaken by Deng Xiaoping with those of Gorbachev, linking them to the divergent outcomes of reform and revolution in their respective countries.

Improving STEM (science, technology, engineering, and mathematics) education and strengthening the STEM workforce have long been acknowledged as national priorities. Ceaseless efforts have been made to address these national priorities through educational research, innovative STEM education initiatives, and professional development for teachers. Engaging STEM Students From Rural Areas: Emerging Research and Opportunities is an essential reference source that discusses the potential of rural schools to impact the STEM workforce pipeline, as well as Project Engage, an educational program for preparing rural undergraduate students from the Alabama Black Belt region. Featuring research on topics such as the three-pillar approach for preparing tomorrow's STEM professionals, this book is ideally designed for academicians, STEM educational researchers, STEM educators, and individuals seeking coverage on techniques to improve the undergraduate STEM education framework.

Based on longitudinal ethnographic work on migration between the United States and Taiwan, Time and Migration interrogates how long-term immigrants negotiate their needs as they grow older and how transnational migration shapes later-life transitions. Ken Chih-Yan Sun develops the concept of a "temporalities of migration" to examine the interaction between space, place, and time. He demonstrates how long-term settlement in the United States, coupled with changing homeland contexts, has inspired aging immigrants and returnees to rethink their sense of social belonging, remake intimate relations, and negotiate opportunities and constraints across borders. The interplay between migration and time shapes the ways aging migrant populations reassess and reconstruct relationships with their children, spouses, grandchildren, community members, and home, as well as host societies. Aging, Sun argues, is a global issue and must be reconsidered in a cross-border environment.

Honor-related values are a source of gendered inequality and of violence. In so-called honor cultures, traditionally located in parts of the Middle East, Mediterranean regions, North Africa, and South America, honor translates into women's roles as dictated by family ideology. There is a direct link between male reputation and the female body. In these matters, East Asian face cultures are similar to but also different from honor cultures. For the first time, this book studies literary together with sociological representations of the loss of honor and of face. Fiction explores honor-based values which impose shackles not only on female but also on male society members. The book is endorsed with prefaces by Turkish writer Sema Kaygusuz and Chinese scholar Ma Chi.

This volume examines the role of objects in the region north of early dynastic state centers, at the intersection of Ancient China and Eurasia, a large area that stretches from Xinjiang to the China Sea, from c.3000 BCE to the mid-eighth century BCE. This area was a frontier, an ambiguous space that lay at the margins of direct political control by the metropolitan states, where local and colonial ideas and practices were reconstructed transculturally. These identities were often merged and displayed in material culture. Types of objects, styles, and iconography were often hybrids or new to the region, as were the tomb assemblages in which they were deposited and found. Patrons commissioned objects that marked a symbolic vision of place and person and that could mobilize support, legitimize rule, and bind people together. Through close examination of key artifacts, this book untangles the considerable changes in political structure and cultural makeup of ancient Chinese states and their northern neighbors.

The roles of women in Chinese archaeology, with only a few exceptions, have at worst been overlooked, and at best consigned to conventional Marxist theory that prescribes formulaic frameworks for understanding gender - until now. Renowned archaeologist Katheryn M. Linduff and fellow researcher Yan Sun have brought together a fascinating collection that reexamines gender in ancient Chinese cultures. Acknowledging and negotiating the complications that challenge their efforts, the authors analyze and begin to reconstruct the roles of women in various regions of China from the late Neolithic to the early Empire period. Topics range from mortuary ritual, social status and structures of power, economic influences on cultural practice, textile production, and art in these early Chinese societies. This book is a must for students, professors, and practitioners of archaeology that seek a more complete examination of the archaeological record, for scholars in the fields of Asian Studies, Art History, and Chinese History more generally, as well as for those interested in the roles of women in ancient Chinese society.

Is corruption an inevitable part of the transition to a free-market economy? Yan Sun here examines the ways in which market reforms in the People's Republic of China have shaped corruption since 1978 and how corruption has in turn shaped those reforms. She suggests that recent corruption is largely a byproduct of post-Mao reforms, spurred by the economic incentives and structural opportunities in the emerging marketplace. Sun finds that the steady retreat of the state has both increased mechanisms for cadre misconduct and reduced disincentives against it. Chinese disciplinary offices, law enforcement agencies, and legal professionals compile and publish annual casebooks of economic crimes. The cases, processed in the Chinese penal system, represent offenders from party-state agencies at central and local levels as well as state firms of varying sizes and types of ownership. Sun uses these casebooks to illuminate the extent and forms of corruption in the People's Republic of China. Unintended and informal mechanisms arising from corruption may, she finds, take on a life of their own and undermine the central state's ability to implement its developmental policies, discipline its staff, enforce its regulatory infrastructure, and fundamentally transform the economy.
