Communicating COVID-19 risk changes: Signalling with words, phrases, and messages.

During COVID-19, governments issued messages to trigger action, encourage sustained behaviours (e.g., social distancing, hand hygiene), and manage system wide risk.

Checks and balances: a business-oriented lens on disaster management and warnings.

Small businesses are critical to community recovery from disasters. However, factors that affect outcomes (such as planning, information needs, and responses to warnings) are understudied. To address the research record's focus on policy that favours disaster mitigation rather than response, this project applied a two-phased, mixed-method approach.

Trust, but verify: social media models for disaster management.

A lack of trust in the information exchanged via social media may significantly hinder decisionmaking by community members and emergency services during disasters. The need for timely information at such times, though, challenges traditional ways of establishing trust. This paper, building on a multi-year research project that combined social media data analysis and participant observation within an emergency management organisation and in-depth engagement with stakeholders across the sector, pinpoints and examines assumptions governing trust and trusting relationships in social media disaster management.

Risk Perception and the Public Acceptance of Drones.

Unmanned aircraft, or drones, are a rapidly emerging sector of the aviation industry. There has been limited substantive research, however, into the public perception and acceptance of drones. This article presents the results from two surveys of the Australian public designed to investigate (1) whether the public perceive drones to be riskier than existing manned aviation, (2) whether the terminology used to describe the technology influences public perception, and (3) what the broader concerns are that may influence public acceptance of the technology.
