“…On the one hand, previous results have found empirical evidence in university contexts of the presence of various proximity factors linked to social, cultural, geographical, academic and personal aspects that favour the formation of links between students. On the other hand, although learning and work relations, as well as inter- and inter-group learning relations in academic relationship-based settings have received notable attention in the literature, for example, in Australia (Neri & Ville, 2008 ), Spain (Hernandez-Nanclares et al, 2017 ; Tomás-Miquel et al, 2016 ), The Netherlands (Hommes et al, 2012 ; Hommes et al, 2014 ) and the UK (Héliot et al, 2020 ; Rienties & Héliot, 2018 ; Rienties & Tempelaar, 2018 ), specific studies on homophily or proximity factors in these contexts are still scarce, thus requiring further attention.…”
