k

-core is simply a subgraph in which all nodes have at least

neighbors but it need not even be connected.

The boundaries of structural endogamy in a kinship group are a special case of structural cohesion.

Software

Cohesive.blocking is the R program for computing structural cohesion according to the Moody-White (2003) algorithm. This wiki site provides numerous examples and a tutorial for use with R.

Examples

Some illustrative examples are presented in the gallery below:

The 6-node ring in the graph has connectivity-2 or a level 2 of structural cohesion because the removal of two nodes is needed to disconnect it.
The 6-node component (1-connected) has an embedded 2-component, nodes 1-5
A 6-node clique is a 5-component, structural cohesion 5

Perceived cohesion

Perceived Cohesion Scale (PCS) is a six item scale that is used to measure structural cohesion in groups. In 1990, Bollen and Hoyle used the PCS and applied it to a study of large groups which were used to assess the

psychometric qualities of their scale.^[3]
