The book consists of four chapters. The first one contains information about the topic which introduce the projects characteristics, and, at the same time, provide the background for further theoretical and methodological reflection. The second chapter contains a list of research problems and questions, a presentation of the philosophical worldviews (research paradigms) of the project team who guided the planned research and which resulted in the adoption of research strategies compatible with them, and, consequently, procedures and techniques for obtaining source materials and their analysis. In the third chapter, we present a set of terms, ideas, and concepts which inspired the project team as useful tools for describing and analysing the phenomenon under study. The fourth chapter is a kind of ligature that binds together all the previous findings, it is a summary of integrating ideas, concepts, as well as the adopted research procedures and techniques.
