This approach offers valuable insights for modeling the entire life cycle of innovation adoptions (Chang, 2010).
The evolution of the community during the period of investigation as analyzed through dynamic filters of NodeXL was consistent with the normal distribution curve (Figures 1-4), as proposed by Diffusion of Innovations Theory (Rogers, 2003). …
