"The book outlines the theoretical and methodological challenges in analyzing social networks that overlap online and offline. It offers an introduction to concepts, theories, and methods that sit at the crossroads between spatial and social network analysis. It explores a range of networks and discusses methods and approaches to plot a social network graph onto a map. The book takes a non-mathematical approach to social networks and spatial statistics. A bespoke R package using igraph and network provides the online tools needed for mapping and graphing. Suitable for postgraduate students in sociology, psychology and the social sciences"--

Literature on influence operations has identified metrics that are indicative of social media manipulation, but few studies have explored the lifecycle of low-quality information. We contribute to this literature by reconstructing nearly 3 million messages posted by 1 million users in the last days of the Brexit referendum campaign. While previous studies have found that on average only 4% of tweets disappear, we found that 33% of the tweets leading up to the referendum vote are no longer available. Only about half of the most active accounts that tweeted the referendum continue to operate publicly, and 20% of all accounts are no longer active. We tested whether partisan content was more likely to disappear and found more messages from the Leave campaign that disappeared than the entire universe of tweets affiliated with the Remain campaign. We compare these results with an assorted set of 45 hashtags posted in the same period and find that political campaigns present much higher ratios of user and tweet decay. These results are validated by inspecting 2 million Brexit-related tweets posted over a period of nearly 4 years. The article concludes with an overview of these findings and recommendations for future research.

Literature on influence operations has identified metrics that are indicative of social media manipulation, but few studies have explored the lifecycle of low-quality information.

In this article we trace the development of two narratives describing social media that informed much of internet scholarship. One draws from McLuhan's axiom positing that communication networks would bring forth a 'global village', a deliberate contradiction in terms to foreground the seamless integration of villages into a global community. Social media would shrink the world and reshape it into a village by moving information instantaneously from any location at any time. By leveraging network technology, it would further increase the density of connections within and across social communities, thereby integrating geographic and cultural areas into a village stretching across the globe. The second narrative comprises a set of metaphors equally inspired by geography but emphasizing instead identity and tribalism as opposed to integration and cooperation. Both narratives are spatially inspired and foreground real-world consequences, either by supporting cooperation or by ripping apart the fabric of society. They nonetheless offer opposing accounts of communication networks: the first is centered on communication and collaboration, and the second highlights polarization and division. The article traces the theoretical and technological developments driving these competing narratives and argues that a digitally enabled global society may in fact reinforce intergroup boundaries and outgroup stereotyping typical of geographically situated communities.

This study unpacks the emerging framework of detection, verification, and correction of falsehoods developed by fact-checkers outside Western, Educated, Industrialized, Rich, and Democratic countries. We explore a series of semistructured interviews carried out in several languages with thirty-seven fact-checking experts from thirty-five organizations in twenty-seven countries across Africa, Asia, Latin America, and Eastern Europe. Our findings emphasize the contextual nature of the falsehoods that these professionals deal with on a daily basis, and the many strategies they employ to navigate cultural and political obstacles while strengthening social cohesion locally. We review these findings against the literature in the area and argue that the prevailing framework of fact-checking, where misinformation and disinformation are reduced to individual and behavioral problems, underplays the social and historical dimensions driving disinformation and propaganda.

In this article, we chart the conflicting standards of fact-checking outside Western, Educated, Industrialized, Rich, and Democratic (WEIRD) countries that shifted their focus from holding politicians to account to acting as content moderators. We apply reflexive thematic analysis to a set of interviews with 37 fact-checking experts from 35 organizations in 27 countries to catalog the pressures they face and their struggle with tasks that are increasingly different from the journalistic values underpinning the practice. We find that fact-checkers have to balance the number of checks across each side of the partisan divide, an exercise in "bothsidesism" to manage the expectations of partisan social media users; that they increasingly prioritize the checking of viral content; and that Meta's third-party fact-checking program prevents them from holding local politicians to account. We conclude with a discussion of our findings and recommendations for content moderation outside WEIRD countries.

In this paper we uncover a network of Twitterbots comprising 13,493 accounts that tweeted the U.K. E.U. membership referendum, only to disappear from Twitter shortly after the ballot. We compare active users to this set of political bots with respect to temporal tweeting behavior, the size and speed of retweet cascades, and the composition of their retweet cascades (user-to-bot vs. bot-to-bot) to evidence strategies for bot deployment. Our results move forward the analysis of political bots by showing that Twitterbots can be effective at rapidly generating small to medium-sized cascades; that the retweeted content comprises user-generated hyperpartisan news, which is not strictly fake news, but whose shelf life is remarkably short; and, finally, that a botnet may be organized in specialized tiers or clusters dedicated to replicating either active users or content generated by other bots.

This paper introduces a group of politically-charged Twitter users that deviates from elite and ordinary users. After mining 20M tweets related to nearly 200 instances of political protest from 2009 to 2013, we identified a network of individuals tweeting across geographically distant protest hashtags and revisited the term serial activists. We contacted 191 individuals and conducted 21 in-depth, semi-structured interviews thematically-coded to provide a typology of serial activists and their struggles with institutionalized power. We found that these users have an ordinary following, but bridge disparate language communities and facilitate collective action by virtue of their dedication to multiple causes. Serial activists differ from influentials or traditional grassroots activists and their activity challenges Twitter scholarship foregrounding the two-step flow model of communication. The results add a much needed depth to the prevalent data-driven treatment of political Twitter by describing a class of extraordinarily prolific users beyond influentials and the twittertariat.

Transnational activism endures as a political practice turning a mirror onto the world's powerbrokers. We analyse a variety of transnational activism best characterized as serial by virtue of an observed systematic time and border-spanning commitment to protest communication. Following statistical disambiguation of a dataset of 2.5 million unique Twitter users, we identified a subset of exceptionally prolific communicators and interviewed 21 of them. We show that a noted prominence in networked communication of otherwise unremarkable Twitter users may be an upshot of purposive strategies intended to publicize, support or help orchestrate collective action. Accordingly, we propose the term "engagement compass" to address the relationship between activists' life-patterns and their personal investment in protest over time.
