“…With distant roots in the formal sociology of Georg Simmel and the innovative graphical representations of social relations introduced by Jacob L. Moreno in the 1930s (Erikson, 2013), SNA refers 'to the study of the relationships among actors or nodes that give rise to a corresponding network', aiming 'to measure and accurately represent structural relations, explain why they occur, and examine their consequences' (Baxter et al, 2018: p. 199). In international relations, a network approach expands the focus of analysis from the attributes and material capabilities of political actors to the way in which the 'persistent patterns of relations among agents' in a network can define, enable, and constrain those agents (Hafner-Burton et al, 2009: p. 561), for instance affecting states' international status (Baxter et al, 2018), orienting their diplomatic networks (Kinne, 2014), influencing how they collaborate internationally (Kinne, 2013) and how they share information, beliefs, or norms (Hafner-Burton et al, 2009). Also, international political sociology has used SNA, for instance to analyse transnational networks and their role in policy formation (Bigo, 2016;De Graaff and Van Apeldoorn, 2019;Bernhard, 2011).…”
