Article: Node centrality in weighted networks: Generalizing degree and shortest paths. April 21, 2010 at 10:37 am. A paper called “Node centrality in weighted networks: Generalizing degree and shortest paths” that I have co-authored with Filip Agneessens. Will be published in Social Networks. Otherwise, a preprint with the exact same text. This articles proposes a new generation of node centrality measures for weighted networks. The second generation of measures takes into consideration both the weig...

Securely using R and RStudio on Amazon’s EC2. October 17, 2011 at 3:32 pm. R is a great tool for analysing data. It consists of an intuitive and interactive programming language with a vast number of extension packages (such as tnet. That allow analysts to take advantage of functions created by individuals outside the R core team. As such, it is rapidly becoming (or has it already become? Reprogramme everything in (and learn) C. The downside to using cloud computing is security. When I first started ...

Why Anchorage is not (that) important: Binary ties and Sample selection | Tore Opsahl
https://toreopsahl.com/2011/08/12/why-anchorage-is-not-that-important-binary-ties-and-sample-selection
Why Anchorage is not (that) important: Binary ties and Sample selection. August 12, 2011 at 1:39 am. A surprising finding when analysing airport networks is the importance of Anchorage airport in Alaska. In fact, it is the most central airport in the network when applying betweenness! Betweenness for a node is defined as the number of shortest paths among all others that passes through the node (see Opsahl et al., 2010. Issue 1: Binary ties. Then there is a potential for measurement error. The table ...

Closeness centrality in networks with disconnected components. March 20, 2010 at 1:03 pm. To develop this measure, I went back to the original equation:. Is the focal node,. Is another node in the network, and. By taking advantage of this feature, it is possible to rewrite the closeness equation as. The sum of inversed. Distances to all other nodes instead of the. Inversed of the sum. Of distances to all other nodes. The equation would then be:. Social Networks 32, 245-251. What to try it with your data?

Degree Centrality and Variation in Tie Weights. August 8, 2011 at 11:28 pm. Represents all other nodes,. Is the total number of nodes, and. Is the adjacency matrix, in which the cell. Is defi ned as 1 if node. Is connected to node. Degree has generally been extended to the sum of weights when analysing weighted networks, and labeled node strength (Barrat et al., 2004). This measure can be formalised as follows:. Is the weighted adjacency matrix, in which. Is greater than 0 if the node. Load tnet library(...

Boards and Gender
http://www.boardsandgender.com/index.php
This website is the 2-year continuation of a research project on board memberships and gender in Norway (see Seierstad and Opsahl, 2011. In Seierstad and Opsahl (2011). On boards of public limited companies, and made the boards more balanced in terms of gender. At a fundamental level, our data indicate that the legislative mandate of the Norwegian Government was a successful enabler for improving gender balance on corporate boards. In addition, our analysis indicates possible counter-effects of the law.
