Beyond Rio+20: governance for a green economy

This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.As an intellectual contribution to the preparations for the 2012 United Nations Conference on Sustainable Development (UNCSD, a.k.a. Rio +20), the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future convened a task force of experts to discuss the role of institutions in the actualization of a green economy in the context of sustainable development. A stellar group of experts from academia, government and civil society convened at the Pardee Center and were asked to outline ideas about what the world has learned about institutions for sustainable development from the past, and what we can propose about the governance challenges and opportunities for the continuous development of a green economy in the future. The Task Force members were encouraged to think big and think bold. They were asked to be innovative in their ideas, and maybe even a little irreverent and provocative. They were charged specifically NOT to come to consensus about specific recommendations, but to present a variety and diversity of views. This report presents their thoughts and ideas

Wide binaries as a critical test of Classical Gravity

Modified gravity scenarios where a change of regime appears at acceleration scales $a<a_{0}$ have been proposed. Since for $1 M_{\odot}$ systems the acceleration drops below $a_{0}$ at scales of around 7000 AU, a statistical survey of wide binaries with relative velocities and separations reaching $10^{4}$ AU and beyond should prove useful to the above debate. We apply the proposed test to the best currently available data. Results show a constant upper limit to the relative velocities in wide binaries which is independent of separation for over three orders of magnitude, in analogy with galactic flat rotation curves in the same $a<a_{0}$ acceleration regime. Our results are suggestive of a breakdown of Kepler's third law beyond $a \approx a_{0}$ scales, in accordance with generic predictions of modified gravity theories designed not to require any dark matter at galactic scales and beyond.Comment: accepted for publication in EPJ

Typing of Scedosporium apiospermum by multilocus enzyme electrophoresis and random amplification of polymorphic DNA36708

The genetic diversity among epidemiologically unrelated strains of the human pathogenic fungus Scedosporium apiospermum or its teleomorph, Pseudallescheria boydii, from different areas in Europe, was investigated by multilocus enzyme electrophoresis (MLEE) and random amplification of polymorphic DNA (RAPD). Fourteen enzyme activities were analysed by starch gel electrophoresis, corresponding to 27 polymorphic loci and 43 iso-enzymes. Among the enzymes studied, propionate esterase, carboxyl esterase, superoxide dismutase, carbonate dehydratase and malate dehydrogenase were the most polymorphic, allowing the classification of the strains into 6-11 groups each. Combination of the data obtained for the different enzyme activities studied allowed differentiation of the strains. Similarly, a high polymorphism was also revealed by each of the 20 RAPD primers tested, but no single primer was able to differentiate all the strains. The most efficient primers were GC70, UBC-701 and UBC-703, which revealed 17 distinct genotypes each, and combination of the results obtained with this three-primer set allowed complete discrimination of the strains. The dendrograms obtained from MLEE or RAPD by the unweighted pair-group method using arithmetic average cluster analysis did not reveal any clustering according to the geographic origin of the strains or their pathogenicity</p
