Of course, we were able to transform this an attributive
variable – spheres of activity of NGO – in relational one and to measure the
number of joint spheres of activity (denoted by S
ij) by the following expression: where x
ij is the number of spheres
of activity by NGOs
i and
j, x
i
is the total number of spheres of activity of NGO
i, and x
j is
the total number of spheres of activity of NGO
j. This measure ranges from zero (no joint spheres) to one (only
joint spheres). The same technique of measure was used by Val Burris (2005:
257) in his study of interlocking directorates. However, we have decided not to
do this computation because our observations show that Kazakhstani NGOs are
easily to change the sphere of activity (in other words, this category is very
changeable).where x
