The text we present is the result of a valuable opportunity offered by the ERASMUS+ program within the BIP (Blended Intensive Program) action, which we accessed as the University of Perugia. This project has fruitfully stimulated universities that have been collaborating for a long time. All three institutions were driven to take advantage of the new short mobility program to organize and offer advanced training courses capable of exploring the various theoretical paths developed in different research centers. The universities involved in this case were: the University of Perugia, together with those of Catholic Lyon, and Valencia. Mobility has thus proved to be a very effective means. Through dialogue and the exchange of perspectives, it has been possible to deepen reflections that intersect. In this way, we have provided supplementary training for participating university students. These students, coming from the three universities, had access to innovative research topics, gaining valuable insights to stimulate new study paths. This took place during the BIP (Blended Intensive Program) 2024, which was held in the first week of July in Perugia. This study and training program involved three universities with a long-standing partnership with the University of Perugia, institutions that are now even more interconnected thanks to a multilateral agreement that has also facilitated closer collaboration among us.
