L201。, which we briefly review later. 4 .4 Towards NonTraditional SNA Recently, the social work analysis munity has been concerned over the use (and misuse) of metrics and validation techniques for both the empirical and simulated works. With the plethora of available measurement tools, it has bee immensely important to choose carefully the most suitable set of metrics depending upon the context of the underlying study. For example, whether it is about the spread of disease, 15 asymmetric information exchange, dyadic friendships relations etc。 we however, restrict to reporting a few most relevant points. For any social works, the atomic units are obviously the individuals. In gathering data about individuals, it is quite useful to identify the general spatiotemporal constraints that limit most individuals39。 ? Familial and sexual relationships, (if any), within the groups etc. A primary objective for fieldwork researchers is to identify the boundaries of social groups that exist among the actors or the stakeholders and investigating the features that distinguish them. Definition: Boundaries from Schensul et. al. (1999) “ Boundaries constitute the edges of works and are defined by rules for entry and exit from groups as well as by other cultural patterns of participation that differentiate one group from another.” al. remends, it is really important to interview as many as possible people in the casestudy areas, as people39。 or that the neighbors of a node are more likely to be linked to each other than in a pure random work. Networks As explained by Albert and Barabasi (2020), just using the ER or the WS models just does not capture the two important aspects of realworld works. First is the assumption that the number of starting nodes is fixed and is not changed. Secondly, in the random works, the chances of a node being linked to another are equally likely. Realworld works not only evolve over time but also exhibit the notion of preferential attachment , where the likelihood of a node being connected depends upon the number of edges it has. The Barabasi and Albert model (BA) tackles the two aspects in two steps: of the work: This starts with a small number of nodes, say, N and each time step, a new node m is introduced in the work.。 effect. A seminal contribution was made by the sociologist Stanley Milgram whose study based on social works led to the term 39。.Jensen (1998) insists that SOC cannot be manifested with utility maximizing agents. ?

The term umbrellas the size, similarity of structure and dynamics in the observed works, which belong to a variety of disciplines, from natural and physical sciences, social sciences to the the last decade, extraordinary advancements have been made in the studies of plex works. The studies have resulted in identifying characteristic works and their relevant measures. A prehensive review may be found in (Newman, 2020。 involved in modeling the behavior of a natural or artificial system. Definition: Complexity as defined by Edmonds( 2020) “ Complexity is that property of a model which makes it difficult to formulate its overall behaviour in a given language, even when given reasonably plete information about its atomic ponents and their interrelations. ” Complex Networks Networks have been studied formally at least as early as from the 18 th century, where Euler pioneered the Graph Theory in his attempt to solve the famous K246。nyi, (the socalled ER model) in the 1950s. The basic ER model requires connecting N nodes through n edges chosen randomly such that the resulting work is from a space of graphs, each equally likely.
