For example, in Europe (Kastlunger, et al, 2013;Kirchler, et al, 2008;Kogler, et al, 2013;Pellizzari & Rizzi, 2014;Siglé, et al, 2018;Wahl, et al, 2010) and later Asia (Andyarini, Subroto, & Subekti, 2019;Batrancea & Nichita, 2014;Damayanti & Martono, 2018;Faizal et al, 2017;Mardhiah, Miranti & Tanton, 2019), Africa (Ayuba, Saad & Ariffin, 2018;Mas' ud, et al, 2015;Mas'ud, et al, 2014), and South America (da Silva, Guerreiro & Flores, 2019). However, most of these validations are country specific, except a few such as Mas' ud, et al, (2015) and Mas'ud, et al, (2014) that have a continental focus with emphasis on Africa.…”
