theoretical concepts, data, and even a few disagreements, all of which were extremely beneficial for the quality of this dissertation. Advices given by my second supervisor, Luís Tinoca, as well as the rest of the EDiTE consortium including Michael Schratz, Hana Cervinkova and Milan Pol, have also been a great stimulus and inspiration for continuing to work hard towards developing the well-rounded piece of study that is before us. I would like to express my gratitude to the examination board, including Erika Kopp and Fernando Albuquerque Costa, as well as the pre-defence opponents, Atilla Varga and János Győri, for the interesting conversations and debates around my doctoral topic. These conversations helped me in the final stages of writing that focused on finetuning the entire written piece and preparing a sound dissertation.A special thanks also has to go to the administrative support provided by EDiTE technical secretariat, especially the kind colleagues in Budapest and Lisbon, who provided invaluable support during my field research and in all the administrative hurdles we had. Next to this, I do need to mention the research community of the EDiTE network and my research colleagues who have helped me mirror my thoughts, develop concepts, and understand my own writing from different angles, especially Malte Gregozewski, Vasileios Symeonidis, Josefine Wagner and Csilla Pesti. Of course, there should be a mention of the many schools in Hungary and Portugal that have opened their doors and were always eager to talk to me. Their involvement has left a bright positive impression on me and their selfless insights were priceless to this research.Finally, I would like to acknowledge and thank for the support I received from my partner, Elena Cason, who made my work tolerable and my struggles bearable by always being ready to travel back and forth to visit me. When seriously needed, she would take me away from work to travel to foreign destinations where we would engage in discussions that would boost my inspiration. I am also grateful for a great deal of cooking, care and jokes from my family, especially my mother and father, my brother Viktor and my grandmother Erzsebet, that made it easy for me to advance to the very end.Overall, a special thanks to the European Commission and the funding received through Horizon 2020 flagship initiative and the Marie Skłodowska Curie programme, that enabled this project and provided necessary monetary allocation for my research.
