Figure 6. Mined data of frequencies of OCCs resulting from the node after removal of the top 10, 250, 500, 750 and 1000 nodes ranked according to various network parameters. Each line color represents a SNA parameter.
Network-based risk index
From the above analysis, we can discriminate the parameters that best capture the temporal network’s vulnerability and resilience. Thus, we selected the parameters that resulted in the greatest reduction in OCC (Degree, Betweenness, Closeness, and reverse PageRank) for our network-based risk index and index pop. These indexes were calculated to quantify spatial patterns and identify municipalities that were hotspots for movement. The network-based results, either raw or standardized for swine population size, are shown in Figures 7 and 8, respectively. The municipalities that played a key role in the pig trade network in SC state for both maps were Concórdia, Seara, and Videira.
