“…The hypothesis is that, whilst the evolutionary principles of systems theory have been integrated into multiple, evolving transition frameworks which underlie development of policy, the unique contribution to knowledge concerning sustainability focused innovation (referred to as the phenomenon of interest or POI ) provided by the distinct systems framework, has been under-realised. A comparative metatheoretical study of the epistemological and political foundations of theory ( Burrell and Morgan, 1979 ; Edwards, 2014 ; Lewis and Grimes, 1999 ) is used to explore this proposition. The emerging Geography of Transitions literature ( Coenen and Truffer, 2012 ; Murphy, 2015 ; Shove and Walker, 2007 ; Truffer et al., 2015 ), with its systemic, spatial focus, is considered alongside systems theory ( Bertalanffy, 1968 ; Francois, 2006 ; Luhmann, 1995 ).…”
