Power in Networks http://www.orgnet.com Copyright © 2004, Valdis Krebs They say the golden rule in Real Estate is: Location, Location, Location . Might this rule also hold in social networks? In real estate, location is determined by geography – your physical location. In social networks, location is determined by your connections and the connections of those around you – your virtual location. Two social network measures, Betweenness and Closeness, are particularly revealing of a node’s advantageous or constrained location in a network. The values of both metrics are dependent upon the pattern of connections that a node is embedded in. Betweenness measures the control a node has over what flows in the network – how often is this node on the path between other nodes? Closeness measures how easily a node can access what is available via the network – how quickly can this node reach all others in the network? A combination where a node has easy access to others, while controlling the access of other nodes in the network, reveals high informal power . We will look at a simple human network and watch how power changes in the network based on connections made and lost in the network over time
