“…When two spaces get close to each other, they form a variety of structural patterns, characterised by existing concepts such as ‘structural coupling’ (Luhmann, 1984/1995), ‘linked ecologies’ (Abbott, 2005), ‘field overlap’ (Evans & Kay, 2008), ‘Russian Doll fields’ (Fligstein & McAdam, 2012), ‘proximate fields’ (Lei, 2016), ‘adjacent ecologies’ (Block-Lieb & Halliday, 2017) or ‘overlapping ecologies’ (Liu, 2017). There are also discussions of ‘interstitial fields’ (Medvetz, 2012), ‘spaces between fields’ (Eyal, 2013) or ‘linking ecology’ (Serafin, 2019), all of which focus on the areas between adjacent social spaces. Nevertheless, little effort has been made to integrate this growing vocabulary into a coherent framework for understanding the social distance between social spaces.…”
