BACKGROUND The value of workplace-based assessments such as the mini-clinical evaluation exercise (mini-CEX), and clinicians' confidence and engagement in the process, has been constrained by low reliability and limited capacity to identify underperforming trainees. We proposed that changing the way supervisors make judgements about trainees would improve(More)
Disturbances affect almost all terrestrial ecosystems, but it has been difficult to identify general principles regarding these influences. To improve our understanding of the long-term consequences of disturbance on terrestrial ecosystems, we present a conceptual framework that analyzes disturbances by their biogeochemical impacts. We posit that the ratio(More)
In Western North America, increasing wildfire and outbreaks of native bark beetles have been mediated by warming climate conditions. Bioclimatic models forecast the loss of key high elevation species throughout the region. This study uses retrospective vegetation and fire history data to reconstruct the drivers of past disturbance and environmental change.(More)
