SOCIAL NETWORK THEORY (SNT)
The Social Network Theory (SNT) as an area of work or study in the fields of social sciences deals with modeling the complex relationships between people (Yang, Yang, Zhang, & Spyrou, 2010) and relates to human communities varying between small numbers of individuals to the whole population (Ethier, 2006). Beginning with the early 1930s, SNT has evolved mainly from psychology, anthropology, and mathematics (Hatala, 2006). These days, researchers have utilized SNT and its concepts as a promising research approach in different branches and fields (Quatman & Chelladurai, 2008).
