“…The boundaries that these bridging ties cross can be disciplinary, scalar (Andersson et al, 2014;Hamilton & Lubell, 2018), geographic (Fischer & Jasny, 2017), or financial (Barendse, Roux, Currie, Wilson, & Fabricius, 2016), among others. Boundary organizations might be formally created to be so, as is the case of the IPCC and other international scientific assessments (Hoppe, Wesselink, & Cairns, 2013; see also Leifeld & Fisher, 2017), or may come to this position as a result of network dynamics and mechanics (Ernstson et al, 2010). While most of the literature is still overwhelmingly positive about the role of brokers in this area, a few studies have highlighted the additional amount of time, work, and resources demanded by these roles, as well as other negative results like decreased trust among those who occupy these positions (M. Stovel & Shaw, 2012).…”
