Contextual barriers to mobile health technology in African countries: a perspective piece

On a global scale, healthcare practitioners are now beginning to move from traditional desktop-based computer technologies towards mobile computing environments[1]. Consequently, such environments have received immense attention from both academia and industry, in order to explore these promising opportunities, apparent limitations, and implications for both theory and practice[2]. The application of mobile IT within a medical context, referred to as mobile health or mHealth, has revolutionised the delivery of healthcare services as mobile technologies offer the potential of retrieving, modifying and entering patient-related data/information at the point-of-care. As a component of the larger health informatics domain mHealth may be referred as all portable computing devices (e.g. mobile phones, mobile clinical assistants and medical sensors) used in a healthcare context to support the delivery of healthcare services

Ray-Singer Torsion, Topological field theories and the Riemann zeta function at s=3

Starting with topological field theories we investigate the Ray-Singer analytic torsion in three dimensions. For the lens Spaces L(p;q) an explicit analytic continuation of the appropriate zeta functions is contructed and implemented. Among the results obtained are closed formulae for the individual determinants involved, the large $p$ behaviour of the determinants and the torsion, as well as an infinite set of distinct formulae for zeta(3): the ordinary Riemann zeta function evaluated at s=3. The torsion turns out to be trivial for the cases L(6,1), L((10,3) and L(12,5) and is, in general, greater than unity for large p and less than unity for a finite number of p and q.Comment: 10 page

BRST Quantisation and the Product Formula for the Ray-Singer Torsion

We give a quantum field theoretic derivation of the formula obeyed by the Ray-Singer torsion on product manifolds. Such a derivation has proved elusive up to now. We use a BRST formalism which introduces the idea of an infinite dimensional Universal Gauge Fermion, and is of independent interest being applicable to situations other than the ones considered here. We are led to a new class of Fermionic topological field theories. Our methods are also applicable to combinatorially defined manifolds and methods of discrete approximation such as the use of a simplicial lattice or finite elements. The topological field theories discussed provide a natural link between the combinatorial and analytic torsion.Comment: 24 pages. TEX error of first version corrected: a \input is delete

Climate of the nation 2014 - Australian attitudes on climate change: are Australians climate dinosaurs?

Synopsis: Are Australians climate dinosaurs? Climate of the Nation 2014, benchmarking Australian attitudes to climate change, finds that political leaders risk being stuck in the past as public attitudes on climate change and its solutions are on the rebound. In mid-2014, more Australians think that climate change is occurring and are concerned about impacts, present and future. There is a rebound in desire to see the nation lead on finding solutions and a strong expectation of government to address the climate challenge. Opposition to carbon pricing has continued to decline and there is a decline in the minority supporting repeal. For the first time more support carbon pricing than oppose it, even though there is lingering confusion around it
