“…There is abundant evidence in the educational literature which shows that in-school management support for their learning and development, leadership trust and positive feedback from parents and pupils are key positive influences on teachers' motivation and resilience (e.g. Huberman, 1993;Webb et al, 2004;Brunetti, 2006;Leithwood et al, 2006;Day et al, 2007;Castro et al, 2010;Meister and Ahrens, 2011). Empirical evidence on how successful principals mediate the negative influences of macro-level policy contexts and meso-level external school intake contexts and through this, create a positive school culture which nurtures teachers' capacity for learning and development is also strong and evident (Leithwood et al, 2006;Day and Leithwood, 2007;Gu et al, 2008;Robinson et al, 2009;Leithwood et al, 2010;Sammons et al, 2011;Gu and Johansson, 2013).…”
