“…To answer these questions, we have to trace the intellectual path of the development of SE research that has unfolded through different EMES research projects over the last decades. Through this contribution, the goal is certainly not to summarise all the – numerous, fruitful and thorough – research projects which have been carried out by EMES members, but to show the common thread that runs through several of them – namely, the EMES Project (1996–1999); the PERSE Project (2001–2006); and the ICSEM Project (2011–2021) – and which materialised in some publications that have since become widely cited in the literature (Borzaga and Defourny, 2001; Defourny, 2001; Defourny and Nyssens, 2006; Defourny and Nyssens, 2010; Defourny and Nyssens, 2012; Defourny and Nyssens, 2017; Defourny et al , 2021; and the four ICSEM books, available in Open Access: Gaiger et al , 2019; Bidet and Defourny, 2019; and Defourny and Nyssens, 2021a, 2021b).…”
