“…The first one, unsurprising in view of the structuring of an international, largely European, field of research on 'policy sociology', refers to the work of Stephen Ball, which is very often cited. However, it is less the detailed analysis of policy contexts that is mobilised -we found it explicitly developed in only one article in our corpus (Hyatt & Meraud, 2015) -than the notions of bricolage/assemblage and trajectory that seem to inspire the greatest number of authors (Adrião & Silva, 2020; Álvares, 2018; Barzanò & Grimaldi, 2013;Carvalho et al, 2020;Estrela, 2019;Maroy et al, 2017;Serpieri et al, 2015;Teodoro & Estrela, 2010). This notion of trajectory is sometimes coupled in some articles with the analytical frameworks of historical neo-institutionalism (notion of path dependency, Kathleen Thelen's work on gradual change), which constitute the second main source of theoretical inspiration in the three countries studied (Álvares, 2018;Berthet, 2019;Garcia, 2015;Grimaldi, 2013).…”
