| SNA methods provide specific mathematical definitions of five groups of characteristics of the actors/ nodes and of the network itself (Bonacich, P., 1987; Burt, R. S., 1992):
1. cohesion,
These characteristics are expressed in terms of corresponding network structure parameters derived from the relations among actors. There is vast amount of material is available for the introduction to SNA which can be easily, for example, in (Scott, J., 2000; Hanneman, R. E., 2005; Wasserman, S., Faust, K., 1994). The insights that can be obtained from the various values of the network structures are elaborated in Burt (1990) |
SNA methods provide precise mathematical definitions of five groups of characteristics of the actors and of the network itself [EN 18, EN 19]: cohesion, equivalence (role-groups), power of actors, range of influence, and brokerage. These characteristics are expressed in terms of corresponding Network-Structure parameters derived from the relations among the actors. An introduction to SNA can be found in Scott [20] and Hanneman [21]. For a comprehensive text, see Wasserman and Faust [22]. Burt [13] elaborates on the insights that can be obtained from the various values of the network structures.

Looks like a bonafide overview on the subject done by Nm, but in fact Nm only copies what already could be found in Aviv (2003). No reference to Aviv given. |

| The cohesion index is a measure of the degree to which there are strong links within the clique rather than outside of it (where the strength of a link reflects the number of responses exchanged along the link). If the cohesion index is greater than 1, then the links within the clique are stronger on average than the links with the [outside.] | The Cohesion Index is a measure of the degree to which there are strong links within the clique rather than outside of it (where the strength of a link reflects the number of responses exchanged along the link). If the cohesion is greater than 1, then the links within the clique are stronger on average than the links with the outside. A precise definition is given by Bock and Husain [40]. |
As it is stated in the source: this is not a definition but an informal description. Nevertheless it appears word-for-word in Nm's thesis. No reference given. |
