“…A number of recent studies have focused attention on the last step. In the last five years alone these include network text analyses of abstracts of academic journal articles (Beam, et al, 2014), medical school mission statements (Grbic, Hafferty, & Hafferty, 2013), presidential inaugural addresses (Light, 2014), violent extremist propaganda (Morris, 2014), screenplays and novellas (Hunter & Singh 2015;Hunter & Smith, 2014), energy policy speeches (Shim, Park, & Wilding, 2015), as well as newspaper articles about the global financial crisis (Nerghes, Lee, Groenewegen, & Hellsten, 2015), mad cow disease (Lim, Berry, & Lee, 2015), the creationism debate in the US (Shortell, 2011) and two major cities in Afghanistan (Martin, Pfeffer, & Carley, 2013). In these studies, measures of concept position within the text networks include degree centrality (Shortell, 2011;Grbic, Hafferty, & Hafferty, 2013;Martin, Pfeffer & Carley, 2013;Morris, 2014;) , betweenness centrality (Light, 2014;Shim, Park, & Wilding, 2015;Nerges, Groenewegen, & Hellsten, 2015), and network constraint (Hunter & Singh, 2015).…”
