I've been the supervisor together with dr. Alessandro Inversini of the first Master Thesis on World Youth Day (Madrid 2011), researched by Miriam Stefania in the framework of the Master in International Tourism. The thesis covers the overlapping areas inbetween eTourism, religious Tourism and youth event Tourism.
