Book Description
The news media have significant influence on the formation of public opinion. Called the agenda-setting role of the media, this influence occurs at three levels. Focusing public attention on a select few issues or other topics at any moment is level one. Emphasizing specific attributes of those issues or topics is level two. The Power of Information Networks: The Third Level of Agenda Setting introduces the newest perspective on this influence. While levels one and two are concerned with the salience of discrete individual elements, the third level offers a more comprehensive and nuanced perspective to explain media effects in this evolving media landscape: the ability of the news media to determine how the public associates the various elements in these media messages to create an integrated picture of public affairs. This is the first book to detail the theoretical foundations, methodological approaches, and international empirical evidence for this new perspective. Cutting-edge communication analytics such as network analysis, Big Data and data visualization techniques are used to examine these third-level effects. Diverse applications of the theory are documented in political communication, public relations, health communication, and social media research. The Power of Information Networks will interest scholars, students and practitioners concerned with the media and their social and cultural effects.

Book Description
This comprehensive treatment of network information theory and its applications provides the first unified coverage of both classical and recent results. With an approach that balances the introduction of new models and new coding techniques, readers are guided through Shannon's point-to-point information theory, single-hop networks, multihop networks, and extensions to distributed computing, secrecy, wireless communication, and networking. Elementary mathematical tools and techniques are used throughout, requiring only basic knowledge of probability, whilst unified proofs of coding theorems are based on a few simple lemmas, making the text accessible to newcomers. Key topics covered include successive cancellation and superposition coding, MIMO wireless communication, network coding, and cooperative relaying. Also covered are feedback and interactive communication, capacity approximations and scaling laws, and asynchronous and random access channels. This book is ideal for use in the classroom, for self-study, and as a reference for researchers and engineers in industry and academia.

Book Description
An argument that the movement for network neutrality was of a piece with its neoliberal environment, solidifying the continued existence of a commercially driven internet. Media reform activists rejoiced in 2015 when the FCC codified network neutrality, approving a set of Open Internet rules that prohibitedproviders from favoring some content and applications over others—only to have their hopes dashed two years later when the agency reversed itself. In this book, Russell Newman offers a unique perspective on these events, arguing that the movement for network neutrality was of a piece with its neoliberal environment rather than counter to it; perversely, it served to solidify the continued existence of a commercially dominant internet and even emergent modes of surveillance and platform capitalism. Going beyond the usual policy narrative of open versus closed networks, or public interest versus corporate power, Newman uses network neutrality as a lens through which to examine the ways that neoliberalism renews and reconstitutes itself, the limits of particular forms of activism, and the shaping of future regulatory processes and policies. Newman explores the debate's roots in the 1990s movement for open access, the transition to network neutrality battles in the 2000s, and the terms in which these battles were fought. By 2017, the debate had become unmoored from its own origins, and an emerging struggle against “neoliberal sincerity” points to a need to rethink activism surrounding media policy reform itself.

Book Description
In 2012, the United Nations General Assembly determined that affordable Internet access is a human right, critical to citizen participation in democratic governments. Given the significance of information and communication technologies (ICTs) to social and political life, many U.S. tribes and Native organizations have created their own projects, from streaming radio to building networks to telecommunications advocacy. In Network Sovereignty, Marisa Duarte examines these ICT projects to explore the significance of information flows and information systems to Native sovereignty, and toward self-governance, self-determination, and decolonization. By reframing how tribes and Native organizations harness these technologies as a means to overcome colonial disconnections, Network Sovereignty shifts the discussion of information and communication technologies in Native communities from one of exploitation to one of Indigenous possibility.
