This edited volume explores migration movements to Norway, the Netherlands, the United Kingdom and Portugal from Brazil, Morocco and Ukraine, focusing on how the migration processes of yesterday influence those of today. The central analytical tool for this undertaking is the concept of feedback. This volume identifies various feedback mechanisms that initiate, perpetuate and reverse migration movements. It pays attention to the role of personal networks, but it also moves beyond networks by analysing the role of institutions, macro-level factors and forms of broadcast feedback operating through impersonal channels. Based on extensive surveys and in-depth interviews, it changes our understanding of how and why patterns of international migration change over time.

This book explores the activism promoted by organised networks of civil society actors in opening up possibilities for more democratic supranational governance. It examines the positive and negative impact that such networks of civil society actors – named “interlocutory coalitions” – may have on the convergence of principles of administrative governance across the European legal system and other supranational legal systems. The book takes two main controversial aspects into account: the first relates to the convergence between administrative rules pertaining to different supranational regulatory systems. Traditionally, the spread of methods of administrative governance has been depicted primarily against the background of the interactions between the domestic and the supranational arena, both from a top-down and bottom-up perspective. However, the exploration of interactions occurring at the supranational level between legal regimes is still not grounded on adequate empirical evidence. The second controversial aspect considered in this book consists of the role of civil society actors operating at the supranational level. In its discussion of the first aspect, the book focuses on the relations between the European administrative law and the administrative principles of law pertaining to other supranational regulatory regimes and regulators, including the World Bank, the International Monetary Fund, the World Trade Organization, the United Nations, the Organization for Economic Cooperation and Development, the Asian Development Bank, and the Council of Europe. The examination of the second aspect involves the exploration of the still little examined, but crucial, role of civil society organised networks in shaping global administrative law. These “interlocutory coalitions” include NGOs, think tanks, foundations, universities, and occasionally activists with no formal connections to civil society organisations. The book describes such interlocutory coalitions as drivers of harmonized principles of participatory democracy at the European and global levels. However, interlocutory coalitions show a number of tensions (e.g. the governability of coalitions, the competition among them) that may hamper the impact they have on the reconfiguration of individuals’ rights, entitlements and responsibilities in the global arena.

These discussions help the readers to understand more advanced research materials for developing new ideas to make a contribution in this field for themselves. This book aims to serve as a virtual and effective bridge between academic research in theory and engineering development in practice. Students, professional, and practitioners who seek to learn the latest development in wireless technologies should find interest in this book.

5G and Beyond Wireless Networks: Technology, Network Deployments, and Materials for Antenna Design offers a comprehensive overview of 5G and beyond 5G wireless networks along with emerging technologies that support the design and development of wireless networks. It also includes discussions on various materials used for practical antenna design which are suitable for 5G, beyond 5G applications, and cell-free massive MIMO systems. The book discusses the latest techniques used in 5G and beyond 5G (B5G) communication, such as non-orthogonal multiple access (NOMA), device-to-device (D2D) communication, 6G ultra-dense O-RAN, rate-splitting multiple access (RSMA), simultaneous wireless information and power transfer (SWIPT), massive multiple input multiple output (mMIMO), and cell-free massive MIMO systems, which are explained in detail for 5G and beyond cellular networks. The description of NOMA and their benefit for 5G and beyond networks is also addressed along with D2D communication for next generation cellular networks. RSMA technique is also explained for 6G communication. Detailed descriptions for the design and development of 5G and beyond networks over various techniques are included. The materials specification to design antenna for 5G application are also given. The role of metalens in designing effective antennas and material specifications for 5G applications is explained in this book. Apart from the above emerging topics, this book also gives ideas about intelligent communication, Internet of Multimedia Things (IOMT), millimeter-wave MIMO-UFMC, and fog computing cloud networks. The last chapter gives details about the legal frameworks for 5G technology for responsible and sustainable deployment. Overall, this book may benefit network design engineers and researchers working in the area of next generation cellular networks. The contents of this book will be helpful for young researchers and master students, and network design engineers who are working in the area of next generation cellular networks.

How black Americans use digital networks to organize and cultivate solidarity Unrest gripped Ferguson, Missouri, after Mike Brown, an unarmed black teenager, was shot and killed by Officer Darren Wilson in August 2014. Many black Americans turned to their digital and social media networks to circulate information, cultivate solidarity, and organize during that tumultuous moment. While Ferguson and the subsequent protests made black digital networks visible to mainstream media, these networks did not coalesce overnight. They were built and maintained over years through common, everyday use. Beyond Hashtags explores these everyday practices and their relationship to larger social issues through an in-depth analysis of a trans-platform network of black American digital and social media users and content creators. In the crucial years leading up to the emergence of the Movement for Black Lives, black Americans used digital networks not only to cope with day-to-day experiences of racism, but also as an incubator for the debates that have since exploded onto the national stage. Beyond Hashtags tells the story of an influential subsection of these networks, an assemblage of podcasting, independent media, Instagram, Vine, Facebook, and the network of Twitter users that has come to be known as “Black Twitter.” Florini looks at how black Americans use these technologies often simultaneously to create a space to reassert their racial identities, forge community, organize politically, and create alternative media representations and news sources. Beyond Hashtags demonstrates how much insight marginalized users have into technology.

It also highlights why the respective solutions are so different. The first part of the book provides a detailed technical discussion of UMTS, including original vision, architecture, protocol stacks and overall functionality. It places UMTS in the context of its evolution of from GSM and its convergence with Computer Networks. The second part of the book discusses today’s vision of 4G, and introduces upcoming networking technologies. Emphasis is on LTE / SAE as successor of UMTS; UMB, WiMAX and NGN are also discussed. The book gives an overview of what these technologies are likely to offer, of their architectures, protocols and functionality. It also discusses their differences and similarities, and whether they will qualify as 4G. Key Features: Provides readers, particularly those with a background in IP-based networks, with a technical understanding of what UMTS does, how it works and how it is likely to evolve Explains the differences in design between UMTS Networks and Computer Networks and discusses how these design divergences can be reconciled in the future Shows how economic considerations shape the design of UMTS Motivates why particular design choices are made in UMTS Gives an in-depth introduction to LTE / SAE Provides a detailed picture of the state of the art in 4G Illustrates the theory with numerous tables and figures This comprehensive textbook is essential reading for advanced students and lecturers in communications systems and networking.
