The Chair of the symposium is responsible for its organisation, moderation, as well as inviting a Discussant. A symposium consists of a 90-minute conference session organised by the submitters; it includes 4 or 5 papers per session plus a Discussant, who may evaluate the symposium and raise questions that help to promote discussion and reflection. The Chair is responsible for submitting the symposium summary and abstracts for all papers linked to it. The Chair is the only one to receive the reviewers’ assessment and must inform all contributors about the evaluation.
