The Dynamics of Disaster Recovery: Resilience and Entropy in Hurricane Response Systems 2005–2008

Our data may reveal a weakness in validity, since once an organization is in the system and interacting with other organizations, additional interactions may not be reported everyday by the newspaper. Consequently, the correlations observed overtime are likely to be much higher in reality. Yet, assuming that the newspaper accounts are reliable, (e.g. if there is a bias in terms of reporting the continued interactions among organizations over time, it is similar for both response systems, since the data for the content analysis of the Katrina and Gustav systems are taken from Times Picayune), then comparison of the response systems for Gustav and Katrina are valid since the data for both analyses are collected from the same source
