Summary of network measures used in the proposed activity.

Measure Definition and implications Key references
Node-level Degree centrality •Considers a given node’s number of direct connections•Nodes high in degree centrality have a large number of immediate exchanges of information Borgatti (2005)
Closeness centrality •Considers the average shortest path from a given node to all other nodes in the network•Nodes high in closeness centrality can reach all the other nodes in the network in a short number of steps and, therefore, can be efficient in accessing or sharing information Wasserman and Faust (1994)
Betweenness centrality •Considers the extent to which a given node is positioned between other nodes on their shortest paths, or geodesics•Nodes high in betweenness centrality can serve as a bridge to transport information or control the interactions between other nodes Freeman (1977), Wasserman and Faust (1994)
Eigenvector centrality •Considers the centralities of a given node’s neighbors (in contrast to degree centrality which exclusively relies on the number of connections)•Nodes high in eigenvector centrality are more influential than nodes which have a large number of connections to less central nodes Bonacich (2007)
Overall network-level Diameter •Measures the distance between the two nodes furthest apart in the network, or the largest geodesic distance across the entire network•Represents the maximum distance a piece of information needs to travel in a network Yamaguchi (1994)
Mean geodesic distance •Measures the average number of shortest steps between pairs of nodes•Reflects the overall connectivity of a network and impacts the extent to which information can be shared among nodes in few steps Hanneman and Riddle (2005)
Clique •A cohesive subgroup of nodes that are all directly connected to all others in the group•Members in a clique have constraints in accessing non-redundant information if they do not have ties to nodes outside of the clique Haythornthwaite (1996), Hanneman and Riddle (2005)
Community structure •Structures of densely connected subsets of nodes•Represents social groupings, impacting the flow of information within and across those boundaries Girvan and Newman (2002)
