British Educational Research Journal, EarlyView.Abstract To negotiate quality in early childhood education and care, we must ask from different perspectives what constitutes a good centre for children. The children themselves have only recently been identified as a resource to contribute to that discussion.

Knowing education in Thailand like a global expert organisation: Politics, context and data
British Educational Research Journal, EarlyView.Abstract Global expert organisations play increasingly significant roles in the way that education is understood and governed internationally, including by influencing the discourses through which education is conceptualised and shaping norms of what counts as success, failure, progress and the most desirable visions for the future.

British Educational Research Journal, EarlyView.Abstract Extensive research has shown that students from higher socioeconomic status (SES) backgrounds generally outperform their lower SES peers. Nevertheless, some low SES students succeed, albeit it ‘against the odds.’ Coleman's (1988) theory of social capital in the family suggests that financial capital, human capital and social capital all affect

Center manifolds for evolution equations associated with the Stefan problem [PDF]
, 2017 Evolution equations can be used for solving the Stefan problem. We show the existence of a center manifold for an evolution equation that is associated with a quasilinear Stefan problem with variable surface tension and undercooling.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...

Учёные записки Казанского университета: Серия Физико-математические наукиA Stefan problem of heat transfer in semi-infinite bodies with an arbitrary number of unsteady moving boundaries during phase transitions was solved. Such problems arise when composite materials are heated at high temperatures, causing the binding agents

Business Strategy and the Environment, EarlyView.ABSTRACT Circular ecosystems connect diverse actors who collaborate to close resource loops and pursue sustainable goals without centralized control. Such arrangements entail heightened interdependence and uncertainty, making trust, understood as the willingness to accept vulnerability based on positive expectations of others' behavior, a critical ...
