During the COVID-19 pandemic, social media served as an important channel for the public to obtain health information and disseminate opinions when offline communication was severely hindered. Yet the emergence of social bots influencing social media conversations about public health threats will require researchers and practitioners to develop new communication strategies considering their influence. So far, little is known as to what extent social bots have been involved in COVID-19 vaccine-related discussions and debates on social media. This work selected a period of nearly 9 months after the approval of the first COVID-19 vaccines to detect social bots and performed high-frequency word analysis for both social bot-generated and human-generated tweets, thus working out the extent to which social bots participated in the discussion on the COVID-19 vaccine on Twitter and their participation features. Then, a textual analysis was performed on the content of tweets. The findings revealed that 8.87% of the users were social bots, with 11% of tweets in the corpus. Besides, social bots remained active over three periods. High-frequency words in the discussions of social bots and human users on vaccine topics were similar within the three peaks of discourse.

With the surge in the number of data and datafied governance initiatives, arrangements, and practices across the globe, understanding various types of such initiatives, arrangements, and their structural causes has become a daunting task for scholars, policy makers, and the public. This complexity additionally generates substantial difficulties in considering different data(fied) governances commensurable with each other. To advance the discussion, this study argues that existing scholarship is inclined to embrace an organization-centric perspective that primarily concerns factors and dynamics regarding data and datafication at the organizational level at the expense of macro-level social, political, and cultural factors of both data and governance. To explicate the macro, societal dimension of data governance, this study then suggests the term “social data governance” to bring forth the consideration that data governance not only reflects the society from which it emerges but also (re)produces the policies and practices of the society in question. Drawing on theories of political science and public management, a model of social data governance is proposed to elucidate the ideological and conceptual groundings of various modes of governance from a comparative perspective. This preliminary model, consisting of a two-dimensional continuum, state intervention and societal autonomy for the one, and national cultures for the other, accounts for variations in social data governance across societies as a complementary way of conceptualizing and categorizing data governance beyond the European standpoint. Finally, we conduct an extreme case study of governing digital contact-tracing techniques during the pandemic to exemplify the explanatory power of the proposed model of social data governance.

Over the past decades, waves of political contention involving the use of information and communication technologies have swept across the globe. The phenomenon stimulates the scholarship on digital communication technologies and contentious collective action to thrive as an exciting, relevant, but highly fragmentary and contested field with disciplinary boundaries. To advance the interdisciplinary understanding, Shifting Dynamics of Contention in the Digital Age outlines a communication-centered framework that articulates the intricate relationship between technology, communication, and contention. It further prods us to engage more critically with existing theories from communication, sociology, and political science on digital technologies and political movements. Given the theoretical endeavor, Shifting Dynamics of Contention in the Digital Age systematically explores, for the first time, the influence of mobile technology on political contention in China, the country with the world’s largest number of mobile and Internet users. Using first-hand in-depth interview and fieldwork data, it tracks the strategic choice of mobile phones as repertoires of contention, illustrates the effective mobilization of mobile communication on the basis of its strong and reciprocal social ties, and identifies the communicative practice of forwarding officially alleged “rumors” as a form of everyday resistance. Through this ground-breaking study, Shifting Dynamics of Contention in the Digital Age presents a nuanced portrayal of an emerging dynamics of contention—both its strengths and limitations—through the embedding of mobile communication into Chinese society and politics.

Digital telecommunication technology has expanded the potential of the mobile phone to be used increasingly as a weapon against authoritarian rule and censorship. Since the content of mobile communication is unpredictable and unregulated, mobile phones have the capability to breach state-sponsored blockage of information. This in turn helps the Chinese people to maintain contact with each other, receive information from outside the country, and make political waves in an aggressive battle for control over information. This paper examines spontaneous mobilization via mobile phones, with a focus on two concrete popular protests in rural and urban areas, demonstrating how Chinese citizens have expanded the political uses of mobile phones in their struggle for freedom of information flow, social justice, and the rule of law, while seeking to build an inexpensive counter-public sphere. These processes destabilize China's conventional national public sphere by shaping political identities on an individual level as well as the notion of citizenship within the evolving counter-public sphere. The political significance of mobile phones in the context of contemporary China's political environment can be observed by various social forces that communicate their struggles with the aid of this technology, pose challenges in governance, and force the authorities to engage in new kinds of media practices.

Although scholars have studied issues arising from digital activism, most have failed to scrutinize the possible interconnections that might be found within digitally mediated political contention. To advance such an understanding, this study employs the concept of “cycles of contention” to investigate recurrent mechanisms of protest in contemporary society. This study takes as its case 7 anti-petrochemical (anti-PX) protests in China from 2007 to 2014, during which 54 in-depth interviews were conducted. Whereas traditional media coverage legitimizes and modularizes anti-PX protests, facilitates the adoption of digital media as part of the repertoire of contention, and sustains political contention in the long run, the use of digital media enables protestors to diffuse contention widely and quickly and allows them to learn from the experiences of the past. This study concludes that the sustainability of digitally mediated environmental activism is shaped by the specific communication ecology in China.
