“…In particular, Berger & Luckmann's (1966) conceptualisation of agency's spatial ('here') and temporal ('now') experience of 'everyday life', leads to the notion that reality is socially constructed within 'zones' of 'role specific knowledge', where agency has only temporally and spatially contingent knowledgable competence, and where agents are only intensely interested in those 'manipulative' zones which are involved in their daily occupation of tasks. (Berger & Luckmann, 1966, p. 36) Consequently, when investigating the policy sector, Berger & Luckmann (1966) direct our methodological attention towards the nature of professionalism (Banton et al, 1985;Franklin & Clapham, 1997;Howe, 1991;Sibeon, 1991a;Wilding, 1982) where professionals undertake different roles and possess, mobilise and manipulate their role specific knowledge (to which others do not have equal access or even interest in accessing) in the service of implementing policy.…”
