Factor 1 mean: 0.509 → High global connectivity Factor 2 mean: −2.917 → High local heterogeneity (r.c.) Factor 3 mean: 0.347 → Average local homophily (r.c.) Portals are structurally delineated by their high connectivity as exhibited through strong local heterogeneity and brokerage. They connect with many other actors, especially non-ENGO actors. Based on the brokerage roles loading on factor 2, their high level of local connectivity serves to connect otherwise disconnected actors of all types with each other, except they do not generally serve the coordinator role of connecting two otherwise disconnected ENGOs Factor 1 mean: 0.693 → High global connectivity Factor 2 mean: 0.189 → Average local heterogeneity (r.c.) Factor 3 mean: −1.428 → High local homophily (r.c.) Conduits are structurally identified by their high degree of local homophily and specialized brokerage. They are strongly connected to the whole network, but primarily through connections to other ENGOs. They serve as the most common brokers between otherwise disconnected ENGOs (coordinators), and play a moderate brokerage role between ENGOs and non-ENGOs (gatekeepers), but not between nonENGO actors Factor 1 mean: 0.750 → High global connectivity Factor 2 mean: 0.385 → Average local heterogeneity (r.c.) Factor 3 mean: 0.628 → Low local homophily (r.c.) Members are structurally interesting primarily for being part of the main component, basically being engaged in the field, but without any other major structural distinctions. They score highest on the factor for global connectivity, but have relatively little else to distinguish them structurally Factor 1 mean: −1.351 → Low global connectivity Factor 2 mean: 0.143 → Average local heterogeneity (r.c.) Factor 3 mean: 0.123 → Average local homophily (r.c.) Satellites are most structurally distinctive because they are NOT connected to the main component. They load strongly and negatively onto the global connectivity factor, indicating they are disconnected from the vast majority of the other actors in the field

Example
Members are connected into the main component through their limited ties
Isolates, like N40 on the left, have no connections. Other satellites, like N6 on the right, have limited connections but not into the main component
The example node is the large, labeled circle. ENGOs are circles, corporations are triangles, and foundations are squares. The principal factor associated with each position is presented in italics; members have no distinguishing factor.
