Transnational political communication today is being reconfigured by digital technologies and global power transition. Authoritarian state actors such as China are increasingly active on global social media platforms such as Twitter to directly advance their preferred frames with foreign publics in Western democracies, most notably in what could be called Chinese Twiplomacy contesting narrative globally over contentious issues. This paper problematises such Twiplomacy from authoritarians to Western democracies as 'networked transnational frame contestation', arguing that the political and cultural distance between the sending and target countries, the networked affordance of social media, and the national prism of the target countries, all contribute importantly to the complexity of such frame contestation. Through a case study on China's Twiplomacy in contesting coronavirus narrative in the UK, this paper further provides empirical evidence on how 'networked transnational frame contestation' works between politically and culturally distant countries. Using a mixed-method approach combining social network analysis and discourse analysis, this study finds that China's emotion-evoking discursive strategy draws traction but the authoritarian nature of the highly centralised networkedness and that of its discursive strategy, together with the strong cultural discordance with British publics, lead to networked recontextualisation of its intended frames in Britain. British publics, heavily relying on British political elites and press for foreign affairs, invoke shared cultural reference to recontextualise Chinese frames into culturally resonant counterframes. This study proposes a paradigm of 'networkedness within cascades' to understand frame contestation between politically and culturally distant countries. [ABSTRACT FROM AUTHOR]

During the last three years, numerous research papers have been reported which use social media data to explore several issues related to the COVID-19 pandemic. Bibliometric methods in this work are used to analyze 1427 peer-reviewed documents from the last three years extracted from the Web of Science database. The results of this study show that there was high growth in publications in open access journals with an annual rate reaching 19.3% and they also identify the top cited journals and research papers. The thematic analysis of papers shows that research topics related to social media for surveillance and monitoring of public attitudes and perceptions, mental health, misinformation, and fake news are important and well-developed, whereas topics related to distance-learning education with social media are emerging. The results also show that the USA, China, and the UK have published many papers and received a high number of citations because of their strong international collaboration. [ABSTRACT FROM AUTHOR]

In this paper, the interaction strategies and the evolutionary game analysis of the actions taken by the government and the public in the early days of the epidemic are incorporated into the natural transmission mechanism model of the epidemic, and then the transmission frequency equations of COVID-19 epidemic is established. According to the cumulative confirmed cases of COVID-19 in the UK and China, the upper limit of the spread of COVID-19 in different evolutionary scenarios is set. Using SPSS to perform logistic curve fitting, the frequency fitting equations of cumulative confirmed cases under different evolution scenarios are obtained respectively. The analysis result shows that the emergency response strategy adopted by the government in the early days of the epidemic can effectively control the spread of the epidemic. Combined with the transmission frequency equation of COVID-19 epidemic, measures taken by the government are analyzed. The influence of each measure on the frequency variable is judged and then the influence on the spread of the epidemic is obtained. Finally, based on the above analysis, the government is advised to adhere to the principles of scientific, initiative and flexibility when facing major epidemics. [ABSTRACT FROM AUTHOR]
