A central topic for conservation science is evaluating how human activities influence global species diversity. Humanity exacerbates extinction rates. But by what mechanisms does humanity drive the emergence of new species? We review human-mediated speciation, compare speciation and known extinctions, and discuss the challenges of using net species diversity as a conservation objective. Humans ...

Burns from domestic irons are potentially preventable injuries which can result in significant morbidity.

Epidemiology, management and outcome of these injuries is described, and possible preventative strategies are discussed. We present a retrospective case note review of 50 adult and paediatri...

We investigate the task of compressing an image using different probability models for different regions of the image. In this task, using a larger number of regions would result in better compression of the coefficients of the image but would also require more bits for describing the regions and probability models in the regions. We discuss using quadtrees and windowing for performing the comp...
