讲座内容：The wide adoption of online broadcasting tools, such as Twitter, Weibo and Facebook, has allowed massive online message retransmission in disasters (OMRID). Even though OMRID can have significant effects on disaster recovery, disaster managers and tool designers lack theories for how to facilitate high-quality message retransmission in disasters. In this paper, we explain why prior theories are limited in their ability to explain OMRID due to the assumptions they make. To overcome this problem, we propose a new theory of OMRID with more realistic assumptions. The theory of OMRID provides a unified account of how tool capabilities enable message cues that in turn trigger message receivers’ psychological states which then trigger message retransmission behaviour, and do so differently in different disaster contexts. Overall, the theory contributes by building a new foundation for future research, and by providing useful insights for online broadcasting tool designers and stakeholders involved in disaster management.
