Pandemic activism in comparative perspective
Managing the COVID-19 pandemic required governments to act quickly with little input from legislatures, civil society, and citizens. This crisis created a critical opportunity for populists to fuel distrust in media, government, and science. Using digital media, they and other political leaders can communicate directly with citizens through websites and social media accounts. Furthermore, misinformation on social media circulating during the pand…
Implications of deepfake technology for journalistic practice
This study applies a practice theory lens to explore how deepfake technology impacts journalism. Based on an interview study of journalists and media and journalism experts ( n = 20), we find that on a micro-level, the emergent deepfake technology impacts the presentation and packaging of journalistic output (e.g., heightening possibilities for personalization) as well as skills needed for deepfake verification. We highlight the role of data lite…

Is it politics or privacy? Antecedents of using Telegram, Signal, VK, Parler, and Gettr in five countries
Large social media platforms are criticized for commodifying user data, corporate surveillance, and perceived censorship of political speech. As a result, some users flock to alternative platforms, like Telegram, Signal, VK, Parler, or Gettr. This study examines the roles of political ideology, anti-establishment views, and privacy concerns in the use of these five platforms. Based on survey data gathered in the United States, the United Kingdom,…
The Role of Political Interest in the Relationships Between Privacy Concerns, Social Network Size, and Political Expression on Facebook, Twitter, and Instagram
Studies on the predictors of using social media for political purposes reveal some unexpected complexities: users often disregard institutional privacy concerns to discuss politics online, and the size of social networks positively correlates with political expression on social media. Building on the privacy calculus theory, we explore how political interest interacts with privacy concerns and social network size when users decide to engage in po…
Deepfakes in the context of AI inequalities
This study contributes to research on digital inequalities in the context of artificial intelligence by examining user perceptions of deepfake technology. We focus on the stratification of deepfake knowledge and attitudes towards deepfakes as critical elements of technology access. Based on a survey of 1,421 German internet users, we analyse the role of sociodemographic variables, digital skills, and personal innovativeness in predicting deepfake…
Active vs. passive bystander reactions to online political hostility
Hostility is an important obstacle to constructive online political discourse. Combating online political hostility often involves mobilizing the behavior of bystanders. Bystanders can react actively to online hostility by engaging in counterspeech, or they can react more passively through ‘silencing’ (muting or defriending others). Previous research has established that personality plays an important role in online political expression. We exten…
Ready or not, here I come. How synthetic media challenge epistemic institutions
This editorial examines how synthetic media and deepfakes unsettle the epistemic foundations of contemporary public communication. We outline how rapidly advancing generative technologies erode long-standing assumptions about the authenticity of visual and audiovisual content and challenge the institutional capacities of journalism, science, politics, and the arts to maintain credibility and public trust. The contributions to this Special Issue d…
Using Twitch for politics? The role of personality across five countries
The Role of Self-Efficacy and Intellectual Humility in the Relationship Between Perceived Deepfake Exposure and Media Cynicism
Previous research has highlighted that encounters with deepfakes induce uncertainty, skepticism, and mistrust among audiences. In this study, we relate perceived deepfake exposure to media cynicism. Deepfakes shake users’ sense of reality, increasing a need to rely on epistemic authorities, such as journalistic media, while raising fears of manipulation. Based on uncertainty management theory, we propose that two “epistemic virtues” moderate the …
Deepfakes and Journalism
The possibility of using deepfake technology to create synthetic media content in journalism requires careful ethical deliberations. Being that journalism is a norm-oriented social institution, there should be a commitment to ethical principles, which raises questions about the compatibility of this technology’s application with journalistic norms. There is a lack of knowledge on how these challenges can be addressed. This research presents four …
Concerns about misinformation on Instagram in five countries
Digital Inclusion Through Algorithmic Knowledge
Social media platforms are a critical source of civic and political information. We examine the use of Instagram to acquire news as well as civic and political information using nationally representative survey data gathered in 2019 in the US, the UK, France, and Canada ( n = 2,440). We investigate active curation practices (following news organizations, political candidates or parties, and nonprofit organizations or charities) and passive curati…
Privacy resignation, apathy, and cynicism
The growing trend of collecting data about individuals to track past actions and infer future attitudes and behaviors has fueled popular and scholarly interest in the erosion of privacy. Recent shifts in technologies around machine learning and artificial intelligence have intensified these concerns. This editorial introduces the articles in the special theme on digital resignation and privacy cynicism: concepts developed in the past decade to ex…
Social media platforms for politics
Citizens have increasingly diversified their use of social media platforms, raising questions about which platforms are adopted and for what purposes. We use survey data from four countries (Canada, France, the United States, and the United Kingdom) gathered in 2019 and 2021 ( n = 12,302) about Facebook, YouTube, Instagram, Twitter, Reddit, Snapchat, and WhatsApp. Political ideology predicts the adoption and political uses of all platforms, but R…
Inequalities in privacy cynicism
A growing body of research highlights a trend toward widespread attitudes of privacy cynicism, apathy and resignation among Internet users. In this work, we extend these discussions by concentrating on the concept of user agency. Specifically, we examine how five types of structural constraints-interpersonal, cultural, technological, economic and political-restrict user agency and contribute to the prevalence of privacy cynicism as a common respo…
It's Fine If Others Do It Too
Political expression is a focal point for understanding how digital media have transformed political engagement. Privacy concerns tend to impede online political expression, but this relationship is still poorly understood. Based on the theory of reasoned action, this study focuses on the role of social influence and institutional privacy concerns in political expression on Facebook. We draw on research on the privacy calculus to examine how obse…
L’arrogance du pouvoir
Le désir de gloire installé par Machiavel dans la philosophie politique, instaure la modernité qui va traduire jusqu’à notre époque l’individualisme au cœur du social. Ce recentrage sur l’individu au détriment de l’être social, permet le retour de la volonté au sein de la gouvernance, ce dont l’arrogant se drape pour pavoiser dans son habit de lumière narcissique
Online political participation
The advent of online technologies has been triggering a wave of empirical examinations of online political participation (OPP) over the past twenty years. It also stimulated scholarly debate on how to conceptualize political participation in a digital age. Scholars differ on whether to consider passive and expressive online behaviors part of or a mere precursor to political participation. This study argues that due to its rapid evolution as well …
Powerless in the digital age? A systematic review and meta-analysis of political efficacy and digital media use
Many citizens feel powerless in the current globalized political context, despite the potential of digital media to increase their perceptions of being informed about politics and expand their opportunities to interact with elected officials to try to influence government decisions. We analyzed 193 studies to document the most popular ways to conceptualize, measure, and model political efficacy when also studying digital media. Furthermore, we co…
The contextual role of privacy concerns in online political participation
Research on online political participation highlights how online platforms may facilitate or encumber political participation. In this contribution, we add to existing research on digital inequalities in online political participation by focusing on privacy concerns as a critical construct. We follow a contextual understanding of online privacy and examine a variety of online political behaviours to differentiate the distinctive roles privacy con…
“Doing gender” by sharing
In this study, based on survey data collected from twelve European countries (N=6111), we build on the digital technology access model to examine the role of gender in access to the sharing economy. Applying a "doing gender" perspective, we find that men capitalise on a stronger economic position and a more pronounced orientation to explore new technology to gain access to sharing services, while women rely more on cultural and social capital. We…
Dimensions of digital inequality in the sharing economy
Sharing economy platforms have grown to offer various commercial opportunities to a growing but still limited user base. We conceptualize engagement in the sharing economy as a form of online participation, and apply a digital inequalities perspective to examine the social stratification of commercial sharing. Based on the Internet access model established by Van Dijk, we analyze the effects of social structural antecedents on various access stag…
Feminist women’s online political participation
Citizens in modern democracies have a continuously expanding set of tools at their disposal through which they seek to exercise influence on politics, including digital modes of participation. However, the usage of these tools is still gendered to the disadvantage of women. Feminist attitudes have been shown to have a positive impact on women's political participation, yet this effect is deeply interwoven with the empowering effect of a feminist …
Strategic investor relations management
Purpose While several extant studies have discussed the strategic importance of investor relations (IR) for listed corporations, few have tried to apply findings from strategic communication research to IR. Therefore, little is known about the planning and evaluation of IR programs, with even less data available on IR's involvement in top management decision-making. The purpose of this paper is to examine research on planning and evaluation pract…
Data capitalism and the user
Ever since empirical studies found only a weak, if any, relationship between privacy concerns and privacy behavior, scholars have struggled to explain the so-called privacy paradox. Today, a number of theoretical arguments illuminate users’ privacy rationales, including the privacy calculus, privacy literacy, and contextual differentiations. A recent approach focuses on user resignation, apathy, or fatigue. In this piece, we concentrate on privac…
Feminism! What Is It Good For? The Role of Feminism and Political Self-Efficacy in Women’s Online Political Participation
Despite initial hopes for more egalitarian access to democracy, research has shown that political participation on the Internet remains as stratified as its offline counterpart. Gender is among the characteristics affecting an individual’s degree of political engagement on the Internet—even when controlling for socioeconomic status. To explain this gender divide, it is necessary to go beyond purely resource-based perspectives. Social cognitive th…

Dealing with deepfakes – an interdisciplinary examination of the state of research and implications for communication studies
Using artificial intelligence, it is becoming increasingly easy to create highly realistic but fake video content - so-called deepfakes. As a result, it is no longer possible always to distinguish real from mechanically created recordings with the naked eye. Despite the novelty of this phenomenon, regulators and industry players have started to address the risks associated with deepfakes. Yet research on deepfakes is still in its infancy. This pa…

The impact of use motives on politicians’ social media adoption
Social media are believed to contribute to a more participatory political environment by providing access to online conversations and by facilitating connections between like-minded individuals. Still, politicians seem slow in actually adopting social media into their communication efforts. Based on a survey conducted among politicians active on the federal level in Switzerland, we explore motives of social media use and their impact on social me…

Making Academic Social Capital Visible
The reliable assessment of individual faculty members’ contributions is a key challenge in the governance of research institutions. Traditionally, scientific impact is estimated based on bibliographic analyses. With online platforms, particularly social media, gaining popularity among academics, new opportunities for the analysis of scientific impact arise. Proponents of the “altmetrics” approach hold that both general purpose social media and se…
The impact of online media on stakeholder engagement and the governance of corporations
Online tools such as social media provide new opportunities for citizens and stakeholder groups to be informed, identify common interests, express and share opinions and demands, organize, and coordinate interventions. Therefore, the Internet could be expected to increase stakeholder engagement in corporate affairs and facilitate good governance. In order to provide an overview of current findings on the impact of online media on governance and s…

The privacy implications of social robots
In this contribution, we investigate the privacy implications of social robots as an emerging mobile technology. Drawing on a scoping literature review and expert interviews, we show how social robots come with privacy implications that go beyond those of established mobile technology. Social robots challenge not only users’ informational privacy but also affect their physical, psychological, and social privacy due to their autonomy and potential…
Beyond just politics
This paper presents a systematic literature review of the current state–of–research on online participation. The review draws on four databases and is guided by the application of six topical search terms. The analysis strives to differentiate distinct forms of online participation and to identify salient discourses within each research field. We find that research on online participation is highly segregated into specific sub–discourses that ref…

L’accompagnement méthodologique
L’article a pour objet de mieux cerner ce que recouvre le concept d’accompagnement méthodologique dans l’enseignement supérieur. La première partie propose une typologie des dispositifs d’accompagnement méthodologique en s’inspirant des travaux de Romainville et Noël (1998). Deux dispositifs contrastés d’aide méthodologique, tous deux expérimentés à l’université Joseph-Fourier (UJF) de Grenoble, sont ensuite analysés afin d’identifier les logique…
Content creation on the Internet
Sociodemographic variables are held to impact Internet users’ willingness and ability to productively use online media. This effect can create a ‘participation divide’ between distinct user groups. Recently, studies have enhanced our understanding of the participation divide by differentiating types of online content creation. They found that sociodemographics may only affect specific forms of online participation. We suggest that social cognitiv…

Privacy cynicism
Privacy concerns among Internet users are consistently found to be high. At the same time, these concerns do not appear to generate a corresponding wave of privacy protection behavior. A number of studies have addressed the apparent divergence between users’ privacy concerns and behavior, with results varying according to context. Previous research has examined user trust, lack of risk awareness and the privacy calculus as potential solutions to …
The impact of use motives on politicians’ social media adoption
Social media are believed to contribute to a more participatory political environment by providing access to online conversations and by facilitating connections between like-minded individuals. Still, politicians seem slow in actually adopting social media into their communication efforts. Based on a survey conducted among politicians active on the federal level in Switzerland, we explore motives of social media use and their impact on social me…
The dark side of online participation
Studies on the ‘second-level digital divide’ explore the socio-economic antecedents and effects of (a lack of) user participation on the Internet. At the same time, some have criticized a normatively affirmative bias in online participation research as well as a one-sided focus on observable user activity. This contribution addresses the ensuing call for a more nuanced understanding of online participation in general, and online political partici…
Stuck with ‘electronic brochures’? How boundary management strategies shape politicians’ social media use
Social media provide new opportunities for politicians, such as personalized communication directed at specific communities of interest. Yet despite potential benefits, empirical analyses show that politicians tend to shy away from an active engagement of online audiences. This study explores the effect of politicians’ online boundary management on their use of social media. Ties maintained through social media profiles can be embedded in diverse…

The role of privacy concerns in the sharing economy
Internet-mediated sharing is growing quickly. Millions of users around the world share personal services and possessions with others ‒ often complete strangers. Shared goods can amount to substantial financial and immaterial value. Despite this, little research has investigated privacy in the sharing economy. To fill this gap, we examine the sharing–privacy nexus by exploring the privacy threats associated with Internet-mediated sharing. Given th…
Sharing by proxy
With the future of work increasingly data-driven, platforms automate decisions based on the collection of vast quantities of user data. However, non-users constitute a challenge as they provide little to no data for either platforms or other users. We focus on a category of (non-)users that has not received any attention in research: users-by-proxy. Users-by-proxy make use of sharing services but they are not themselves part of the sharing transa…
