“…Empirical studies taking such an approach have revealed that the frames adopted by journalists are influenced, at the individual level, by journalists’ goals and perceptions of their professional roles ( Bartholomé et al, 2015 ; Castelló and Montagut, 2011 ; Kothari, 2010 ; Tandoc, 2015 ); at the routines level, by established news values and/or practicalities of newsgathering ( Bartholomé et al, 2015 ; Boesman et al, 2017 ; Johnson and Fahmy, 2010 ; Tandoc, 2015 ); at the organizational level, by editorial policies and the degree of freedom journalists have to define their topics ( Kothari, 2010 ), the production context ( Castelló and Montagut, 2011 ), and the views of owners, peers and chief editors ( Tandoc, 2015 ); at the social institution (or extra-media) level, by the frames promoted by their sources ( Boesman et al, 2017 ; Hanggli, 2012 ; Hanggli and Kriesi, 2010 ; Kothari, 2010 ; Tandoc, 2015 ); and at the social systems level, by frames which are culturally familiar because they have been previously used in public debate on other topics ( Boesman et al, 2017 ). Others found further connections between different levels, arguing that external forces put pressures on the organizational level, which in turn are passed on to newsrooms ( Colistra, 2012 ).…”
