“…This idea is closely tied with notions about circulation as a knowledge-making process developed by scholars such as James Secord, Kapil Raj, Lissa Roberts, Sujit Sivasundaram and Arjun Appadurai to name a few, to give visibility to non-European contexts (Raj, 2007;2010;Appadurai, 2001;Secord, 2004;Roberts, 2009;Sivasundaram, 2010), but opposes staunchly, as Xavier Polanco's idea of world-science already suggested in the 1990s (Polanco, 1990), the flattening of asymmetries that they often advocate, and re-centers historical accounts on Europe while dismissing Eurocentrism. In fact, in the meantime the vantage point of the European Periphery, as voiced by the international group Science and Technology in the European Periphery (STEP) (Gavroglu et al, 2008;Gavroglu, 2012) has drawn attention to the need of seriously taking into consideration the exchanges, mediations and negotiations taking place mostly within Europe, as integral components of global accounts (Patiniotis, 2013;Raposo et al, 2014;Gavroglu;Simões, 2016), and has argued for the co-construction of centers and peripheries, insisting on a serious assessment of how asymmetries, including power asymmetries, are built and evolve. It has re-asserted the creative role of European "invisible" actors, intermediaries and go-betweens, "backward" institutional settings, regions and countries, calling for a revision of standard historiographical accounts, and showing that "invisibility" and "backwardness" have to be understood historically.…”
