“…In fact in the daily practice of scientific activity, "The outcome of an interaction is to a large extent dependent on the balancing of contradicting motivations accompanying the establishment of collaborations" (Mayrose & Freilich, 2015). The intensity with which these collaborations develop (intramural/extramural, domestic/international, intradisciplinary/interdisciplinary) varies on the basis of contextual and personal factors, such as gender (Bozeman & Gaughan, 2011;Abramo, D'Angelo, & Murgia, 2013a;Ozel, Kretschmer, & Kretschmer, 2014), age (van Rijnsoever & Hessels, 2011;Aschhoff & Grimpe, 2011;Abramo, D'Angelo, & Murgia, 2017), academic rank (Lee & Bozeman, 2005;Rivellini, Rizzi, & Zaccarin, 2006;Abramo, D'Angelo, & Murgia, 2014), the research discipline involved (Yoshikane & Kageura, 2004;Gazni, Sugimoto, & Didegah, 2012). Even within a single discipline there can be notable heterogeneity in the forms of activating collaboration, due to the different specializations involved (Piette & Ross, 1992;Newman, 2001;Moody, 2004;Abramo, D'Angelo & Murgia, 2013b).…”
