“…Interestingly, in their research another structural factor, the overall density of communication paths in the structural form, also turned out to be relevant in understanding network performance. Since then, the notion of centrality, density and centralisation were considered as one of the key network measures used for studying network effects on individual and group outcomes such as task efficiency, productivity, and improved performance (Alireza Abbasi et al, 2012;Ahuja et al, 2003;Bonacich, 1991;Brass, 1981Brass, , 1985Cross & Cummings, 2004;Faust, 1997;Hossain et al, 2006;Mullen & Eduardo, 1991;Pfeffer, 1980;Salancik & Pfeffer, 1978;Sparrowe et al, 2001 Uddin et al, 2014).…”
