Jorge González Conejero and Rebeca Varela Figueroa attended the kick-off meeting of the European project Takedown held in Vienna from the 12 to the 15 of September. The Takedown project is funded under the call H2020-FCT-2015 (Grant nº700688) of the H2020 Program, and will be developed until September 2019.The Takedown Consortium is formed by a total of 18 partners with a multidisciplinary background, coming from sociological studies, security studies and computer sciences or law, among others. The project aims at generating novel insights on Organized Crime and Terrorism Networks. In order to meet this challenge and to investigate this complex field of research a multidimensional modelling approach is used. The resulting, proprietary TAKEDOWN Model describes social, psychological, economic aspects as well as further dimensions, activities and response approaches. A comprehensive empirical research combined with European and international expert knowledge ensures a valid and intuitive model. The IDT-UAB contributes to the Consortium expertise on security projects, ethical and legal analysis and data protection compliance strategies.
