Sometimes it is necessary to go back to the basics. Some grand concepts are often used to build upon them apparently sophisticated models and explanations. However, NOWHERE are those basic concepts explain. In this section, I would like to provide critical short overviews of some of the terms I deal with in my research. Most of them are actually contested terms and not as taken for granted as anyone would assume reading much of the literature. I would like to provide at a glance some of the main discussions surrounding terms such as culture, migration or diversity, as well as a basic list of references I have found useful to think critically about how I engage with concepts which are, please let do not forget this, socially and politically charged and, more importantly, the way we talk about such concepts DOES affects many people’s lives.
