By incorporating social media strategies into the traditional framework of crisis communication strategies (CCS), this article presents a comprehensive review of the scholarship on CCS within a global context. Through a content analysis of articles published in 11 journals listed in the Social Science Citation Index (SSCI), 73 articles focusing on the social‐mediated crisis management (SMCM) are identified. Findings show that new strategies such as enhancing and transferring from the organizational perspective are added, the stakeholders and their desired strategies are analysed and an asymmetrical CCS pattern from a contextual perspective is proposed within the SMCM research. Results also point out some weaknesses within the current literature. An interactive crisis communication (ICC) model is proposed for future research agenda.

Purpose Drawing on theoretical insights from the persuasion knowledge model (PKM), this study aims to propose and test a model that maps out the antecedents, process and consequences to explain how consumers process and respond to fake news about brands on Facebook. Design/methodology/approach Contextualizing the fake news about Coca-Cola’s recall of Dasani water, an online survey was conducted via Qualtrics with consumers in the USA (N  =  468). Data were analyzed using covariance-based structural equation modeling. Findings Results showed that self-efficacy and media trust significantly predicted consumers’ persuasion knowledge of the fake news. Persuasion knowledge of the fake news significantly influenced consumers’ perceived diagnosticity of the fake news and subsequent brand trust. Furthermore, persuasion knowledge of the fake news mediated the effects from self-efficacy on perceived diagnosticity of the fake news and brand trust, respectively. Originality/value This study contributes to the literature of brand management by examining how consumers process and respond to fake news about a brand. It also extends the persuasion knowledge model by applying it to the context of fake news about brands on social media, and incorporating antecedents (self-efficacy and media trust) and consequences (perceived diagnosticity and brand trust) of persuasion knowledge in this particular context. Practically, this study provides insights to key stakeholders of brands to better understand consumers’ information processing of fake news about brands on social media.

As mobile social network services have been integrated in many people’s daily lives, this study investigated the relationships between gratifications-sought, social network service use on mobile devices, civic attitudes and civic engagement in Mainland China. Data were gathered in a survey of 760 university students. Results showed that gratifications for technological convenience (accessibility), information exchange (cognition needs), and social interaction (recognition needs) significantly predicted civic engagement. The results also demonstrated that civic attitudes and social network service use on mobile devices are positively related to civic engagement. These findings well demonstrated the important role of mobile-based communication in connecting citizens to civil society.
