In this module, the students familiarise themselves in detail with a modern field of research prescribed by their research phase supervisor on the basis of original literature (scientific journals and monographs). The focus is on the scientific content, the critical evaluation of literature, scientifically correct presentation and the rules of good scientific practice. On the basis of the literature studies, open issues are defined and the investigations necessary to answer them are discussed and planned. The skills of expert presentation and critical discussion are practised in seminars.
