“…As expected, for betweenness, A11ULS has the highest value, indicating that it has the highest potential to connect Besides, it is not recommended that the network depends so much on a single actor. Actors with the highest betweenness (high and differentiated) have the power to break the link among various actors in the network, weakening the group, and thus must be treated with caution [52]. Centrality analysis also uncovers the betweenness centrality of several actors such as A7, A8, A9, and A10 and all the associations located on the edges of the network, indicating the presence of structural holes.…”
