Ideas about matters of public concern are shaped by the spaces associated with them: Events occur in particular places, political regulations apply to specific territories, people in different locations are differentially affected by issues. Yet, political communication research has neglected the question of how the spaces of public issues are constructed in the public sphere. This is especially true for research on social media communication, which is often perceived as placeless. Yet, social media discourses are driven by unequal attention patterns based on users'interests, resources, and abilities. To understand how these patterns manifest spatially, this interdisciplinary monograph builds on public spheres theory, communication infrastructure theory, and urban sociology to develop the framework of issue spatiality. It focuses on how social media users discuss different places in urban policy issue discourses. By applying the framework to four large-scale Twitter discourses on housing markets and cycling infrastructure in two German cities, Berlin and Frankfurt, the research reveals the spatial patterns and inequalities of social media discourses. It demonstrates that digital discourses are overwhelmingly focused on a small number of places in the urban center. These places emerge as the locus of activism and political controversy, while the urban periphery remains hidden or is discussed in purely administrative terms. Places with dense civic infrastructure and privileged residents receive disproportionate attention. The book provides an in-depth look at the ways in which socio-spatial inequalities are inscribed in public communication and shape ideas about societal issues.

This book draws from graph theory and a semiotic comparison between language and distributed ledger technologies (also known as Blockchains) to motivate three experiments on language and network structure. The work explores the importance of this concept in different areas of linguistic research and establishes elements of a tentative linguistics of networks. Its empirical investigation is based on data from threads posted to the imageboard Hispachan, which often displays radicalized language and hate speech. The experiments (based on topic modeling and sentiment analysis) reveal an impact of the network structure of interaction on the interaction itself as well as the use of ingroup signalling and emotionally charged vocabulary to expand the network of interaction..

This book brings together two decades of work by the authors on dialogical networks, showing how the concept of the dialogical network developed through series of connected case studies and clarifying the concept through historical analysis. Identifying the key characteristics of dialogical networks and showing that knowledge of them, though formulated in the abstract, is affected by historical contingencies, it demonstrates that work on dialogical networks required the work of a practical historian, connecting contemporary work to foregoing studies. As such, this volume represents an original study of how doing history is a part of research and sheds light on the ways in which people use the past in their social activities.

Recent advances in digitization are transforming healthcare, education, tourism, information technology, and some other sectors. Social media analytics are tools that can be used to measure innovation and the relation of the companies with the citizens. This book comprises state-ofthe-art social media analytics, and advanced innovation policies in the digitization of society. The number of applications that can be used to create and analyze social media analytics generates large amounts of data called big data, including measures of the use of the technologies to develop or to use new services to improve the quality of life of the citizens. Digitization has applications in fields from remote monitoring to smart sensors and other devices. Integration generates data that need to be analyzed and visualized in an easy and clear way, that will be some of the proposals of the researchers present in this book. This volume offers valuable insights to researchers on how to design innovative digital analytics systems and how to improve information delivery remotely.

Networks and Network Analysis for Defence and Security discusses relevant theoretical frameworks and applications of network analysis in support of the defence and security domains. This book details real world applications of network analysis to support defence and security. Shocks to regional, national and global systems stemming from natural hazards, acts of armed violence, terrorism and serious and organized crime have significant defence and security implications. Today, nations face an uncertain and complex security landscape in which threats impact/target the physical, social, economic and cyber domains. Threats to national security, such as that against critical infrastructures not only stem from man-made acts but also from natural hazards. Katrina (2005), Fukushima (2011) and Hurricane Sandy (2012) are examples highlighting the vulnerability of critical infrastructures to natural hazards and the crippling effect they have on the social and economic well-being of a communityand a nation. With this dynamic and complex threat landscape, network analysis has emerged as a key enabler in supporting defence and security. With the advent of ‘big data'and increasing processing power, network analysis can reveal insights with regards to structural and dynamic properties thereby facilitating greater understanding of complex networks, their entities, interdependencies, vulnerabilities to produce insights for creative solutions. This book will be well positioned to inform defence, security and intelligence professionals and researchers with regards to leading methodologies and approaches.

Telecommunications has had a major impact in all aspects of life in the last century. There is little doubt that the transformation from the industrial age to the information age has been fundamentally influenced by advances in telecommunications. Optimization problems are abundant in the telecommunications industry. The successful solution of these problems has played an important role in the development of telecommunications and its widespread use. Optimization problems arise in the design of telecommunication systems and in their operation. The Handbook of Optimization in Telecommunications brings together experts from around the world who use optimization to solve problems that arise in telecommunications. The editors made an effort to cover recent optimization developments that are frequently applied to telecommunications. The spectrum of topics covered includes planning and design of telecommunication networks, routing, network protection, grooming, restoration, wireless communications, network location and assignment problems, Internet protocol, World Wide Web, and stochastic issues in telecommunications. The editors'objective is to provide a reference tool for the increasing number of scientists and engineers in telecommunications who depend upon optimization in some way. Each chapter in the handbook is of an expository nature, but of scholarly treatment, and includes a brief overview of the state-of-the-art thinking relative to the topic, as well as pointers to the key references in the field. Specialists as well as nonspecialists should find this handbook stimulating and helpful.
