This book is an important contribution to the understanding of the complex education policies of the twenty-first century. It unites world renowned comparatists of education in an effort to respond to the challenges raised by the multidimensional and multi-scalar aspects of education policies. In their attempt to decipher the tangled world of education policies, the authors underline the power of numbers, the power of networks and the power of new concepts and methodologies. The power of numbers – education through numbers via students’ assessments and national or international testing impacts upon our educational choices and reinforces its instrumental aspects. The power of networks – sheds light on the complexity of the education global governance network by focusing on how international governmental organisations (IGOs), such as UNESCO, the OECD and the World Bank carry out policy and on the intricate ways an educational concern becomes part of the international agenda. The power of concepts and methods – policymaking is increasingly dynamic and involves many different stakeholders, including states, private corporations, IGOs, scholars and non-profit organisations. Contributors to this volume have developed new conceptual and methodological perspectives to study the circulation of educational models worldwide. A relational notion of space, the concept of ‘diaspora’ as a space of relations of social actors or the global comparative approach and a methodology drawn on actors-network theory are among the propositions yielded by the authors in order to make sense of and grasp the complexity of education policies today. This book was originally published as a special issue of Globalisation, Societies and Education.

Power Laws, Scale-free Networks and Genome Biology deals with crucial aspects of the theoretical foundations of systems biology, namely power law distributions and scale-free networks which have emerged as the hallmarks of biological organization in the post-genomic era. The chapters in the book not only describe the interesting mathematical properties of biological networks but moves beyond phenomenology, toward models of evolution capable of explaining the emergence of these features. The collection of chapters, contributed by both physicists and biologists, strives to address the problems in this field in a rigorous but not excessively mathematical manner and to represent different viewpoints, which is crucial in this emerging discipline. Each chapter includes, in addition to technical descriptions of properties of biological networks and evolutionary models, a more general and accessible introduction to the respective problems. Most chapters emphasize the potential of theoretical systems biology for discovery of new biological phenomena.
This innovative work examines the concept of the informal network and its practical utility within the context of counterterrorism. Drawing together a range of practitioner and academic expertise it explores the character and evolution of informal networks, addressing the complex relationship between kinship groups, transnational linkages and the role that globalization and new technologies play in their formation and sustainability. By analysing the informal branch of networked organization in the context of security policy-making, the chapters in this book seek to address three questions: how do informal networks operate? which combination of factors draws individuals to form such networks? what are their structures? Informal networks are necessarily elusive owing to their ad hoc development, amorphous structures and cultural specificity but they are nonetheless pivotal to the way organizations conduct business. Identifying and manipulating such networks is central to effective policy-making. Terrorism, Security and the Power of Informal Networks argues that informal networks are important to policy-makers and their mastery is critical to success both in tackling the challenges of hostile networks and in the processes of organizational reform currently preoccupying governments. Practitioners, policy-makers and researchers in the fields of international politics, international relations, history and political science will find much to interest them in this timely resource.
Distributing power in high speed, high complexity integrated circuits has become a challenging task as power levels exceeding tens of watts have become commonplace while the power supply is plunging toward one volt. This book is dedicated to this important subject. The primary purpose of this monograph is to provide insight and intuition into the behavior and design of power distribution systems for high speed, high complexity integrated circuits.
Corporate networks, the links between companies and their leaders, reflect a country’s economic organization and its corporate governance system. Most research on corporate networks focuses on individual countries or particular time periods, however, making fruitful comparisons over longer periods of time difficult. This book provides a unique long-term analysis of the rise, consolidation, decline, and occasional re-emergence of these networks in fourteen countries across North and South America, Europe, and Asia in the 20th and early 21st centuries. In this volume, the editors bring together the most internationally well-known specialists to investigate the long-term development of corporate networks. Using a combination of quantitative and qualitative research approaches, the authors describe the main developments and changes in the corporate network over time by focusing on important network indicators in benchmark years, and identify historical explanations for these developments. This unique, long-term perspective allows readers insight into how and why national corporate networks have evolved over time.
Too often, editors Bandana Purkayastha and Mangala Subramaniam have found, marginalized groups in rural or impoverished areas are overlooked by the international economy of knowledge. The Power of Women's Informal Networks describes and evaluates social organization among poor women in South Asia and West Africa as attempts to challenge marginalization. The discerning editors and contributors explicitly consider the situated contexts within which women work together to improve their lives, with a primary focus on international women's agencies.
This book describes methods for distributing power in high speed, high complexity integrated circuits with power levels exceeding many tens of watts and power supplies below a volt. It provides a broad and cohesive treatment of power distribution systems and related design problems, including both circuit network models and design techniques for on-chip decoupling capacitors, providing insight and intuition into the behavior and design of on-chip power distribution systems. Organized into subareas to provide a more intuitive flow to the reader, this second edition adds more than a hundred pages of new content, including inductance models for interdigitated structures, design strategies for multi-layer power grids, advanced methods for efficient power grid design and analysis, and methodologies for simultaneously placing on-chip multiple power supplies and decoupling capacitors. The emphasis of this additional material is on managing the complexity of on-chip power distribution networks.
High penetration of renewable energy sources (RESs) imposes several techno-economic challenges to distribution system operators (DSOs) due to their variability in power generation and, hence, increases the need for additional operational flexibility. Operational flexibility aims at securely covering the possible variations at the minimum cost using emerging flexible alternatives or designing novel local market mechanisms to incentivize flexibility providers. In such a situation, the DSOs can use the potential of flexible options such as energy storages (ESs), demand response (DR), plug-in electric vehicles (PEVs), or on-site fast run generators. However, each of the mentioned flexible resources has its own specific characteristics and requirements that should be taken into account, and this raises the complexity. Optimal network reconfiguration schemes are the other solution for increasing power system flexibility at the distribution level. There is a great research gap related to renewable-based distribution network planning from a flexibility point of view. Therefore, this book aims to discuss the additional flexibility needs introduced by RESs and describe general approaches to analyze the need for and provision of additional flexibility in future distribution networks at both the planning and operational time frames. This book successfully suggests new solutions and techniques to increase the flexibility in distribution systems. It also highlights the needs for moving towards smart distribution grids in order to enhance the flexibility in modern and future power systems.

This exciting resource covers the fundamentals of wireless and PLC technologies. Different types of wireless and PLC technologies used for indoor IoT applications are described. The channel models for both wireless and power line communications are introduced, highlighting the main challenges for these types of communications inside the indoor environment. The book explores the hybrid technologies with television white space (TVWS), very high frequency (VHF) wireless technology, and broadband PLC (BPLC) for indoor high speed IoT networks. A TVWS standardized BPLC system is proposed, which integrates the requirement of primary user sensing and the permissible transmission power spectral density (PSD) for TVWS users into BPLC standard, regarding VHF band access. The hybrid ultra-high frequency (UHF) wireless-powerline sensor networks with a focus on enlarging the network lifetime via cross-layer optimization is presented. Hybrid video sensor networks (HVSNs) with high data rate requirement are explored. Through the joint design of video encoding rate, aggregate power consumption, channel access control, along with link rate allocation, a distributed algorithm is developed, which divides the computational burden among all nodes with much lower communication overhead. The effectiveness of the cross-layer designs are evaluated through extensive simulation results.
A hands-on troubleshooting guide for VLSI network designers The primary goal in VLSI (very large scale integration) power network design is to provide enough power lines across a chip to reduce voltage drops from the power pads to the center of the chip. Voltage drops caused by the power network's metal lines coupled with transistor switching currents on the chip cause power supply noises that can affect circuit timing and performance, thus providing a constant challenge for designers of high-performance chips. Power Distribution Network Design for VLSI provides detailed information on this critical component of circuit design and physical integration for high-speed chips. A vital tool for professional engineers (especially those involved in the use of commercial tools), as well as graduate students of engineering, the text explains the design issues, guidelines, and CAD tools for the power distribution of the VLSI chip and package, and provides numerous examples for its effective application.
