On 6 September 2022, the BAPS project team gave a webinar as a part of the Qual2Rule initiative: Using qualitative data to inform behavioural rules. The presentation, given jointly by (in the order of appearance) Jakub Bijak, Martin Hinsch, Ariana Modirrousta-Galian, Souhila Belabbas and Adelinde Uhrmacher (standing in for Oliver Reinhardt), was entitled "Capturing the complexity of human migration: Towards an interdisciplinary model-building process" and summarised the project work, including during the extension period, with focus on the role of primary data in model construction - both ethnographic and experimental.
