Towards a Methodology for Validation of Centrality Measures in Complex Networks

Towards a Methodology for Validation of Centrality Measures in Complex Networks | Building Networks | Scoop.it

Our empirical analysis demonstrates that in the chosen network data sets, nodes which had a high Closeness Centrality also had a high Eccentricity Centrality. Likewise high Degree Centrality also correlated closely with a high Eigenvector Centrality. Whereas Betweenness Centrality varied according to network topology and did not demonstrate any noticeable pattern. In terms of identification of key nodes, we discovered that as compared with other centrality measures, Eigenvector and Eccentricity Centralities were better able to identify important nodes.

The elegant law that governs us all

The elegant law that governs us all | Building Networks | Scoop.it

 

A dog owner weighs twice as much as her German shepherd. Does she eat twice as much? Does a big city need twice as many gas stations as one that is half its size? Our first instinct is to say yes. But, alas, we are wrong. On a per-gram basis, a human requires about 25% less food than her dog, and the larger city needs only 85% more gas stations. As Geoffrey West explains in Scale, the reason behind these intriguing phenomena is a universal law known as allometry—the finding that as organisms, cities, and com­panies grow, many of their characteristics scale nonlinearly.

Sensitive Dependence of Optimal Network Dynamics on Network Structure

Sensitive Dependence of Optimal Network Dynamics on Network Structure | Building Networks | Scoop.it
The relationship between the structure and dynamics of a network is key to understanding the behavior of complex systems. A new analysis shows how network optimization, whether designed or evolved, can lead to collective dynamics that depend sensitively on the structure of the network.

12 Empowering Ways to Engage in Civic Affairs

12 Empowering Ways to Engage in Civic Affairs | Building Networks | Scoop.it
It's evident that there's a growing desire among people, especially here in the U.S., to get involved in civic affairs. While online organizing can be an effective means of bringing about change, there's something powerful about showing up in person to talk with public officials and connect with others who are fighting for the same causes. We've pulled together a list of 12 ways to boost civic engagement. The list includes several suggestions from Lawrence Grodeska, founder of CivicMakers, a San Francisco-based social enterprise that offers collaborative civic tech tools, consulting, and other services for public agencies and nonprofits.
