String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Reception Baseline Assessment and ‘small acts’ of micro‐resistance

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...

Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

When Do CEO Temporal Focus and Board Interlocks Lead to Eco‐Innovation? A Configurational Approach

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In this study, we examine how different corporate governance profiles—combinations of CEOs' temporal focus profiles and board interlocks—shape corporate eco‐innovation. Integrating insights from the upper echelon perspective and the attention‐based view, we argue that board interlocks serve as conduits for new knowledge and capabilities that ...
