Definitions of Terms Used in Table

Degree Centrality: number of connections to other members of the network

Non-redundant ties: number of non-redundant ties in relation to the other members that each organization is connected to

Closeness Centrality: Measures how far each member is from other members of the network in terms of # of links between each member. A high score (close to 1) indicates members who have the shortest ‘distance’ between all other members

Total Trust: Average of the ranking given by all other members for that organization along three dimensions: reliability, support of mission, and open to discussion. (Scale of 1–4)
