2.1.3. Net scale of influences (NS)
The net scale of direct and indirect influences measures, for every couple of actors, the distance
between the direct, and indirect influence. Each actor exerts (receives) direct, and indirect
influences of order 2 (from) each actor. The net influence scale will indicate for each couple of
actors the surplus influence either exerted or received (Appendix 2). The next step is to calculate
for each actor the total difference of direct, and indirect influences by adding up the net influence
scales on the rest of the actors. These results are illustrated in the histogram below (figure 18).

NS
The direct, and indirect influence net
scale is calculated in the following way:
(NS) ij = (MDII) ij – (MDII) ji
Values are relative whole numbers:
The (+) sign indicates the actor exerts more
influence than it receives;
The (-) sign indicates the actor exerts less
influence than it receives.
