Protests in new democracies about stolen elections, demonstrations in old democracies against austerity measures, occupied squares all over the world against inequality and for better governance. Some argue that contentious politics gains importance and party politics declines. Is that so and why would that be? Why is it that some individuals engage in politics while others remain apathetic? Why is it that some citizens take the electoral route, while others engage in contentious politics? The truth is that we do not really know. Should we bother? I think we should. Citizens who are actively involved in politics are an asset to democracy. Understanding how and why people take part in politics would help to build more democratic societies. The proposed project compares participation in contentious and non-contentious politics in various countries within a single theoretical and methodological framework. A central tenet of this research proposal is that sooner or later every citizen might get involved in politics. I seek the reason why in the interplay of dynamics at the individual, the organizational, and the societal level. What are the motives people have? What are the appeals parties and movement organizations disseminate; and what are the opportunities and constraints regimes impose? Comparison is the core of the project. It encompasses four subproject: (1) a meta-analysis of publications on movement and party politics; (2) comparisons of political participation over time and countries in global survey data; (3) focus group discussions to understand the formation of political engagement and disengagement in four old democracies (the Netherlands, Germany, Switzerland, U.S.A.), two post-communist new democracies (Hungary, Romania) and two post-authoritarian new democracies (Brazil, Argentina) and Greece as a country that was hit harder than any country by the financial crisis; (4) experimental focused surveys among 1000 respondents to quantify patterns of political participation in the same nine countries.

We present two powerful semiclassical formulas for quantum systems with classically chaotic dynamics, one of them being the Fourier transform of the other. The first formula evaluates the autocorrelation function of a state constructed in the neighborhood of a short periodic orbit, where the propagation for times greater than the Ehrenfest time is computed through the contribution of homoclinic orbits. The second formula evaluates the square of the overlap of the proposed state with the eigenstates of the system, providing valuable information about the scarring phenomenon. Both expressions are successfully verified in the Bunimovich stadium billiard. © 2012 American Physical Society.

Aqueous dissolution of a synthetic chloride-containing Mg2+-Al3+ layered double hydroxide was studied at 298K as a function of pH. Mild acidification (final pH 9 -5) results in incongruent dissolution of Mg2+, exclusively. Formation of an amorphous Al(OH)3 passive layer prevents further Mg2+ leaching, thus dissolved Mg2+ amounts for only 20% of the solid. At lower pH values, massive dissolution readily takes place in a congruent fashion. Congruent dissolution profiles are accounted for by a contracting volume kinetic law. The pH dependence of the observed rate constant shows that the kinetic order on proton concentration is 0.41, indicating that dissolution is surface controlled. The implications of these findings are discussed. © 2010 Elsevier B.V.

Frataxin is a nuclear-encoded mitochondrial protein highly conserved in prokaryotes and eukaryotes. Its deficiency was initially described as the phenotype of Friedreich's ataxia, an autosomal recessive disease in humans. Although several functions have been described for frataxin, that is, involvement in Fe-S cluster and heme synthesis, energy conversion and oxidative phosphorylation, iron handling and response to oxidative damage, its precise function remains unclear. Although there is a general consensus on the participation of frataxin in the maintenance of cellular iron homeostasis and in iron metabolism, this protein may have other specific functions in different tissues and organisms. © 2011 IUBMB.

Chikungunya virus (CHIKV) transmission has been detected in America in 2013 and recently reached south up to Bolivia, Brazil and Paraguay, bordering countries of Argentina. The presence of the mosquito Aedes aegypti in half of the country together with the regional context drove us to make a rapid assessment of transmission risk. Temperature thresholds for vector breeding and for virus transmission, together with adult activity from the literature, were mapped on a monthly basis to estimate risk. Transmission of chikungunya by Ae. aegypti in the world was seen at monthly mean temperatures from 21-34ºC, with the majority occurring between 26-28ºC. In Argentina temperatures above 21ºC are observed since September in the northeast, expanding south until January and retreating back to the northeast in April. The maximum area under risk encompasses more than half the country and around 32 million inhabitants. Vector adult activity was registered where monthly means temperatures exceeded 13ºC, in the northeast all over the year and in the northern half from September-May. The models herein proposed show that conditions for transmission are already present. Considering the regional context and the historic inability to control dengue in the region, chikungunya fever illness seems unavoidable. © 2015, Fundacao Oswaldo Cruz. All rights reserved.
