“…There is a consensus in the literature that in case study research cases should be added until theoretical saturation, or information redundancy has been reached (Mills, Durepos, & Wiebe, 2009, p. 838). It should be noted that in the previous years I have carried out research related to the aims of the present thesis (Nagy, 2017a;Nagy, 2017c;Dessewffy, Nagy, & Váry, 2018;Nagy, 2018), that I do not detail here, as they either do not fit into the present research framework or do not add relevant knowledge to what is to be discussed here. I believe that the case studies described here allow for a holistic but focused discussion of the issues at stake.…”
