This book covers various aspects of political communication in dissonant public spheres and their impact on democratic processes. It expands research on campaigning beyond assumptions of well-functioning political systems, to better understand how the erosion of institutional legitimacy and trust affects communication processes. The volume approaches the concept of dissonant public spheres from four divergent perspectives: as instrumental threats to democracy, as communication performed by political actors, forms of engagement by citizens, and the nature of political conflicts. New perspectives are developed on how political candidates, organizations, and parties optimize their behaviour within dissonant political environments. These disrupted online communication environments reshape public spheres and change citizen engagement in ways that amplify political conflicts and crises. Chapters also examine the role of data-driven campaigning and address how limited access to platform data affects our understanding of dissonant public spheres. A significant new contribution to the field of political communication, this volume will be a key resource for scholars and researchers of communication studies, politics, media studies and sociology. The chapters in this book were originally published in Political Communication.

This book constitutes the poster papers presented during the 22nd International Conference on Human-Computer Interaction, HCII 2020, which was held in July 2020. The conference was planned to take place in Copenhagen, Denmark, but had to change to a virtual conference mode due to the COVID-19 pandemic. From a total of 6326 submissions, a total of 1439 papers and 238 posters have been accepted for publication in the HCII 2020 proceedings before the conference took place. In addition, a total of 333 papers and 144 posters are included in the volumes of the proceedings published after the conference as “Late Breaking Work” (papers and posters). These contributions address the latest research and development efforts in the field and highlight the human aspects of design and use of computing systems. The 62 papers presented in this volume are organized in topical sections as follows: HCI theory, methods and tools; mobile and multimodal interaction; interacting with data, information and knowledge; interaction and intelligence; user experience, emotions and psychophysiological computing.

Jürgen Habermas’s book The Structural Transformation of the Public Sphere, first published in 1962, has long been recognized as one of the most important works of twentieth-century social thought. Blending philosophy and social history, it offered an account of the public sphere as a domain that mediates between civil society and the state in which citizens could discuss matters of common concern and participate in democratic decision-making through the formation of public opinion. Now, in view of the digital revolution and the resulting crisis of democracy, he returns to this important topic. In this new book Habermas focuses on digital media, in particular social media, which are increasingly relegating traditional mass media to the background. While the new media initially promised to empower users, this promise is being undermined by their algorithm-steered platform structure that promotes self-enclosed informational ‘bubbles’ and discursive ‘echo chambers’ in which users split into a plurality of pseudo-publics that are largely closed off from one other. Habermas argues that, without appropriate regulation of digital media, this new structural transformation is in danger of hollowing out the institutions through which democracies can shape social and economic processes and address urgent collective problems, ranging from growing social inequality to the climate crisis.

The successful Brexit referendum campaign; Donald Trump’s election; and the rise of right-wing nationalist-populist political parties and movements – all of these events have incited renewed interest in public communication and the internetised media, deliberative democracy and public spheres, challenged by an informational abundance that generates a communicative liquefaction of publicness and politics. This book celebrates the 25th anniversary of the journal Javnost – The Public, bringing together internationally renowned scholars from 20 countries to discuss topical issues in contemporary media and communication research. It focuses on challenging issues of the changing nature of publicness and the public sphere in the internet age, issues of democracy and the crisis of public communication and the tasks of media and communication research as a social practice. It critically reflects on the democratisation crisis and the demise of popular and scholarly optimism, which the emerging internet inspired in early 1990s, when Javnost – The Public was founded.

The fabric of democracy is threadbare in many contemporary societies. Connections that are vital to the functioning and integrity of our democratic systems are wearing thin. Citizens are increasingly disconnected — from their elected representatives, from one another in the public sphere, and from complex processes of public policy. In such disconnected times, how can we strengthen and renew our democracies? This book develops the idea of democratic mending as a way of advancing a more connective approach to democratic reform. It is informed by three rich empirical cases of connectivity in practice, as well as cutting-edge debates in deliberative democracy. The empirical cases uncover empowering and transformative modes of political engagement that are vital for democratic renewal. The diverse actors in this book are not withdrawing, resisting or seeking autonomy from conventional institutions of representative democracy but actively experimenting with ways to improve and engage with them. Through their everyday practices of democratic mending they undertake crucial systemic repair work and strengthen the integrity of our democratic fabric in ways that are yet to be fully acknowledged by scholars and practitioners of democratic reform.

A state-of-the-art account of what we know and do not know about the effects of digital technology on democracy.
