“…In the same year, Saxena (2018a) investigated the OGD initiatives among six Middle Eastern countries, Cyprus, Turkey, Egypt, Iran, Lebanon, and Jordan. Research studies on OGDs either focused on a single country (e.g., Tang, et al, 2019;Wang, Shepherd, & Button, 2019;Wieczorkowski & Pawełoszek, 2018) or investigated multiple countries in one study (e.g., Yi, 2019;Nayek, 2018;Lourenço, 2015).
