“…While all actors present in a network have degree centrality, not all actors lie between other actors, and hence, not all have betweenness centrality. In 2016, the UCT (17,18) is the node with the highest betweenness centrality; in 2017, the Auckland University of Technology (AUT) (12,68) and UCT (11,1) have high betweenness centrality; in 2018, the UCT (10,63) and the University of Canberra (8,9) have high betweenness centrality; in 2019, the University College London (UCL) (6,290) and SU (5,96) have high betweenness centrality; in 2020, LBU (8,509), University of New England (UNen) (7,99) and RFU (7,15) have high betweenness centrality; in 2021, RFU (15,39), Birmingham City University (13,55) and AUT (11,4) have high betweenness centrality; and in 2022, LBU (13,5) and AUT (10) have high betweenness centrality. The betweenness centrality values for all organisations between 2016 and 2022 are shown in online supplemental appendix 6.…”
