British Educational Research Journal, EarlyView.Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...

Generating reference evapotranspiration surfaces from the Hargreaves equation at watershed scale [PDF]
Hydrology and Earth System Sciences, 2011 In this study, Hargreaves' formulation is considered to be appropriate for the water and energy balance at a daily scale due to its simplicity of application once the distributed values of temperature are available at cell scale. However, the coefficient

Emotional nourishment begets academic coping during the primary to secondary school transition
British Educational Research Journal, EarlyView.Abstract The transition from primary to secondary school is widely viewed as the most demanding in a child's educational journey. Despite a wealth of research on this transition, little is known about the children's ‘lived experience’ of it across different contexts.

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
Geophysical Monograph Series, Page 325-340., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Revista Brasileira de Engenharia Agrícola e Ambiental, 2007 A evapotranspiração de referência (ETo) representa a perda de água do solo vegetado para a atmosfera devido à evaporação e à transpiração. O modelo de Penman-Monteith demanda variados elementos meteorológicos em sua solução, o que dificulta sua aplicação
