The authors of the works that are part of this collection can be divided into several groups. The first is a group of purely academic researchers. The second group includes academic researchers who also act as engaged intellectuals and publicly known analysts of social phenomena. The third group includes academic researchers with specific experience of serving within different political and economic institutions and who can therefore be seen as belonging to the two worlds - the world of scientific-academic research and the world of decision-making. The above-mentioned different groups co-authored some of the papers in this collection, whereby the papers that they have jointly contributed achieve a positive synergy of the different aspirations and activities of their authors, from the purely academic to practical and applied fields.
