Development of Ultra-High Performance Concrete against Blasts: From Materials to Structures presents a detailed overview of UHPC development and its related applications in an era of rising terrorism around the world. Chapters present case studies on the novel development of the new generation of UHPC with nano additives. Field blast test results on reinforced concrete columns made with UHPC and UHPC filled double-skin tubes columns are also presented and compiled, as is the residual load-carrying capacities of blast-damaged structural members and the exceptional performance of novel UHPC materials that illustrate its potential in protective structural design.

As a notable representative, ultra-high performance concrete (UHPC) has now been widely investigated by government agencies and universities. UHPC inherits many positive aspects of ultra-high strength concrete (UHSC) and is equipped with improved ductility as a result of fiber addition. These features make it an ideal construction material for bridge decks, storage halls, thin-wall shell structures, and other infrastructure because of its protective properties against seismic, impact and blast loads.

Focuses on the principles behind UHPC production, properties, design and detailing aspects Presents a series of case studies and filed blast tests on columns and slabs Focuses on applications and future developments

This book provides a fresh interpretation of how Chinese civilization was created and transformed in the process of its early formation (1766-221 BC). It describes the principal features of that civilization which had a profound impact on the later development of Chinese history. In particular, it discusses in detail the main characteristics of the social and political organizations of that period, and argues that, contrary to the traditional interpretation, economic development in ancient China had its own dynamism.

Rural enterprises have played an important role in the extraordinary success of China's economy over the last two decades. They have greatly increased off-farm employment in rural areas and brought substantially increased incomes and standards of living to many rural people. Jun Li provides a comprehensive analysis of the financing of China's rural enterprises over the reform period, and discusses the key aspects of rural enterprise development in China, including the growth of rural enterprises and enterprise-level behaviour, the role of state policy, rural financial institutions and local government. Brings new and challenging analysis to the current debate on the Chinese financial system and the financing of SMEs.

In the past three decades, China has successfully transformed itself from an extremely poor economy to the world’s second largest economy. The country’s phenomenal economic growth has been sustained primarily by its rapid and continuous industrialization. Currently industry accounts for nearly two-fifths of China’s gross domestic product, and since 2009 China has been the world’s largest exporter of manufactured products. This book explores the question of how far this industrial growth has been the product of government policies. It discusses how government policies and their priorities have developed and evolved, examines how industrial policies are linked to policies in other areas, such as trade, technology and regional development, and assesses how new policy initiatives are encouraging China’s increasing success in new technology-intensive industries. It also demonstrates how China’s industrial policies are linked to development of industrial clusters and regions.

Although Chinese economic growth continues strong, and although China coped very well with the recent global crisis, the Chinese economy faces many challenges, including how to sustain growth, how to rebalance the economy towards more domestic consumption, how to accommodate rising wages, growing social and regional inequality, and how to reform financial and monetary policies. This book examines the key challenges currently facing the Chinese economy. It considers Chinas’ increasing global impact, discusses the institutional drivers of China’s economic growth, assesses critically China’s need for structural reform, and explores issues related to sustainability and human rights.

China has grown to become the world’s second largest economy in merely three decades and entrepreneurship has been identified as a key driver of China’s fast growth. Since the mid-2000s, the country has transitioned from a predominance of necessity-based entrepreneurship to that of an opportunity-based entrepreneurship.The China Surveys of Global Entrepreneurship Monitor in the last fifteen years consistently indicate the country’s high rate of entrepreneurship. Furthermore, more Chinese entrepreneurs have started setting their sights on business internationalisation. Against this backdrop of a thriving entrepreneurial economy, institutions and business environment are, however, not often viewed as "friendly" to private entrepreneurs and businesses. The "re-emergence" of entrepreneurship suggests a history of struggle to overcome opposition and obstruction, to survive and grow, including "rule ambiguities", rent-seeking, subsidies, and institutional constraints, such as industrial barriers, difficulties in getting access to critical resources, and weak property rights. China has also been experiencing economic slowdown, increase in inequality and worsening environmental problems since the turn of the century, clearly indicating that the rapid development of entrepreneurship in China presents a lot of puzzling questions.Entrepreneurship in China attempts to deal with these unanswered queries as well as provide an insightful and updated understanding of entrepreneurship development in China.The chapters in this book were originally published as a special issue of the journal, Entrepreneurship & Regional Development.

In 1775, Paul Revere, the folk hero of the American Revolution, galloped wildly on horseback through small towns to warn American colonists that the British were coming. In the Internet age, how do we warn vast numbers of computers about impending cyber attacks? Rapid and widespread dissemination of security updates throughout the Internet would be invaluable for many purposes, including sending early-warning signals, distributing new virus signatures, updating certificate revocation lists, dispatching event information for intrusion detection systems and so forth. However, notifying a large number of machines securely, quickly, and with high assurance is very challenging. Such a system must compete with the propagation of threats, handle complexities in large-scale environments, address interruption attacks toward dissemination, and also secure itself. This work describes an alternative system, "Revere", that addresses these problems. Revere builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes.It also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure Revere overlay networks, considering possible attacks and countermeasures. The book presents experimental measurements of a prototype implementation of Revere gathered using a large-scale oriented approach. These measurements suggest that Revere can deliver security updates at the required scale, speed and resiliency for a reasonable cost. The text is designed to meet the needs of researchers and practitioners in industry and graduate students in computer science. It should also be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by Revere. The Revere solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here should be helpful in designing a customized approach for such systems.

The school-to-work transition has been an important topic in the fields of education and sociology research in the past few years. Pre-vocational education, which takes place during lower-secondary school and aims to facilitate the school-to-work transition, is of critical significance in introducing the participants to the world of work and/or in preparing them for entry into further vocational education programs.With a strong comparative nature, Jun Li presents this systematic investigation of the pre-vocational education in Germany and China and analyzes their curricula of pre-vocational education. By combining the methods of content analysis and teacher interview, the author offers an in-depth perspective into the realms of pre-vocational education and reveals the divergences between the prescribed curriculum and the enacted curriculum. The findings also relate closely to an intensively discussed issue in the sociology of education in the past few years, namely the issueof knowledge and its status, function and forms in the school education today.
