The blurry lines between popular media and party propaganda: China's convergence culture through a linguistic lens.

There is a growing body of scholarly evidence that media convergence blurs the boundary between media production and media consumption and obscures the lines between institutions and individuals. Media convergence in the context of China has garnered attention in communication studies and in cultural studies. However, there is a scarcity of research on convergence culture from a linguistic perspective. Recent research has generated initial evidence that state media appropriates a pop-cultural social address for clickbait and information management in China's digital media space. However, the patterns and perceptual reality of linguistic convergence remain unexplored. This study investigates popular and party uses of xiaojiejie 'little older sister', a familiar expression of fictive kinship reborn as a viral personal reference and social address in China's convergence culture. Analysis of the Target Group Index in the Baidu search engine suggests xiaojiejie is gaining ground over its predecessor among young Chinese. Trends analysis of its usage in WeChat public accounts showed that the term has spread from popular media to state media, which employs the viral address to drive clickbait and disguise propaganda. An online survey of young Chinese WeChat users (N=330) on their perception of xiaojiejie headlines from WeChat public accounts showed that respondents could not tell state media uses from popular uses, providing perceptual evidence of the blurry boundaries between popular and state media uses of the viral address. The findings demonstrate the reality of linguistic convergence driven by participatory performance and its perceptual consequences in China's convergence culture.

#MaskOn! #MaskOff! Digital polarization of mask-wearing in the United States during COVID-19.

The coronavirus disease 2019 (COVID-19) has caused an unprecedented public health crisis worldwide. Its intense politicization constantly made headlines, especially regarding the use of face masks as a safety precaution. However, the extent to which public opinion is polarized on wearing masks has remained anecdotal and the verbal representation of this polarization has not been explored. This study examined the types, themes, temporal trends, and exchange patterns of hashtags about mask wearing posted from March 1 to August 1, 2020 by Twitter users based in the United States. On the one hand, we found a stark rhetorical polarization in terms of semantic antagonism between pro- and anti-mask hashtags, exponential frequency increases of both types of hashtags during the period under study, in parallel to growing COVID-19 case counts, state mask mandates, and media coverage. On the other hand, the results showed an asymmetric participatory polarization in terms of a predominance of pro-mask hashtags along with an "echo chamber" effect in the dominant pro-mask group, which ignored the subversive rhetoric of the anti-mask minority. Notwithstanding the limitations of the research, this study provides a nuanced account of the digital polarization of public opinion on mask wearing. It draws attention to political polarization both as a rhetorical phenomenon and as a participatory process.
