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.
