Background: The poor health of South Africans is known to be associated with a quadruple disease burden. In the second National Burden of Disease (NBD) study, we aimed to analyse cause of death data for 1997–2012 and develop national, population group ...

Teachers learning to use the iPad in Scotland and Wales: a new model of professional development [PDF]
In learning to use a new technology like the iPad, primary teachers adopt a diverse range of experiential, informal and playful strategies contrasting sharply with traditional models underpinning professional development which emphasise formal courses ...

There are limits that emerge out of the interactive nature of interactive digital narrative that make authoring it challenging. These limits include exponential branching, where branches in the narrative increase the amount of content needed to be written progressively throughout the work; combinatorial explosion, where increasing combinations of ...

The distribution of word matches between Markovian sequences with periodic boundary conditions [PDF]
Word match counts have traditionally been proposed as an alignment-free measure of similarity for biological sequences. The D2 statistic, which simply counts the number of exact word matches between two sequences, is a useful test bed for developing ...

Model Reduction Near Periodic Orbits of Hybrid Dynamical Systems [PDF]
We show that, near periodic orbits, a class of hybrid models can be reduced to or approximated by smooth continuous-time dynamical systems. Specifically, near an exponentially stable periodic orbit undergoing isolated transitions in a hybrid dynamical ...
