Using the centrality measures, we next created a plot (see Fig. 5) in which the horizontal axis represents actor centrality
in a collaboration network (level of collaboration) and the vertical axis represents centrality in a competition network (level
of competition). The effects of strategic changes due to before–now or now–after events are illustrated using arrows. Furthermore,
to describe the variation behind the aggregated values, we calculated the standard deviation of the sample mean
(SDx) with 80% confidence interval and illustrated these as circles around the data points.
