How to calculate Reagan & McEvily’ (2003) social cohesion in UCINET?
|
Dear Prof.
Borgatti and colleagues,
?
I am new to
UCINET. Now I am trying to obtain the value of “social cohesion”, which is
first introduced in Reagan & McEvily (2003). And later Tortoriello,
Reagans, & McEvily (2012) give a more detailed explanation as follows:

The way I tried
to get this is using the routine in UCINET as follows: Ego Networks → Structural Holes. In the results, in addition to the traditional
measures of structural holes mentioned in Borgatti et al. (2013/2018) like effect
size, efficiency, constraint, and hierarchy, I also obtained a variable named
as “indirects”. I am wondering whether this is the so called “indirect
structural constraints” defined by Burt (1992).
?
But after
checking the correlations between these five SH variables, I found “indirects”
was positively correlated to effect size while negatively correlated to
constraint (raw value without transformation by 1 - constraint). So I guess if
the “indirects” is the right variables I can utilize to obtain the measure of
“social cohesion”, I need to do the transformation like “cohesion = 1 -
indirects”. Am I right? Many thanks in advance!

Best,
