A special acknowledgment goes to Paolo Costa (Università Ca' Foscari di Venezia), Leonie Sandercock (University of British Columbia), Alessandro Balducci (Politecnico di Milano) and Weiping Wu (Columbia University/ACSP) who presented rather stimulating keynote speeches.

The Congress reached a significant number of participants and constituted a memorable event not only for the scientific quality of the presentations but also for the stimulating environment it provided to all the AESOP community.
