Bi-large neutrino mixing and the Cabibbo angle

Recent measurements of the neutrino mixing angles cast doubt on the validity of the so-far popular tri-bimaximal mixing ansatz. We propose a parametrization for the neutrino mixing matrix where the reactor angle seeds the large solar and atmospheric mixing angles, equal to each other in first approximation. We suggest such bi-large mixing pattern as a model building standard, realized when the leading order value of the reactor angle equals the Cabibbo angle.Comment: 4 pages, 2 figs. v2: matches version appearing in Phys.Rev.D, rapid communication

SAMBA: Stochastic Analytical Model with a Bayesian Approach

We develop and estimate a DSGE model for the Brazilian economy, to be used as part of the macroeconomic modeling framework at the Central Bank of Brazil. The model combines the building blocks of standard DSGE models (e.g., price and wage rigidities and adjustment costs) with the following features that better describe the Brazilian economy: (i) a fiscal authority pursuing an explicit target for the primary surplus; (ii) administered or regulated prices as part of consumer prices; (iii) external finance for imports, amplifying the effects of changes in external financial conditions on the economy; and (iv) imported goods used in the production function of differentiated goods. It also includes the presence of financially constrained households. We estimate the model with Bayesian techniques, using data starting in 1999, when inflation targeting was implemented. Model evaluation, based on impulse response functions, moment conditions, variance error decomposition and initial forecasting exercises, suggests that the model can be a useful tool for policy analysis and forecasting.

O direito administrativo na complementação dos tipos penais no âmbito ambiental

Orientador : Prof. Msc. Fernanda BourgesMonografia (especialização) - Universidade Federal do Paraná, Setor de Ciências Agrárias, Curso de Especialização em Direito AmbientalInclui referênciasResumo : O presente trabalho de conclusão de curso –TCC se insere na temática da Complementação do Direito Administrativo nos tipos penais ambientais, no Curso de Pós-graduação em Direito Ambiental da Universidade Federal do Paraná. Quanto à metodologia usada neste trabalho é teórica, pois o mesmo contribui para o avanço do conhecimento dos conceitos estudados. A pesquisa apresenta como base a Lei 9.605/98, que dispõe sobre as sanções penais e administrativas na esfera ambiental que se utiliza de tipos penais abertos, fazendo remissões a dispositivos administrativos. E, neste sentido, que a conceituação da Assessoriedade Administrativa,na esfera ambiental, possibilita a valoração do comportamento do indivíduo sob o prisma de uma ponderação de interesses entre o homem e o meio ambiente e a correta aplicabilidade das sanções penais ambientai

Unknowns after the SNO Charged-Current Measurement

We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO neutral-current measurement can not fix the fraction of solar $\nu_e$ oscillating to sterile neutrinos. The large uncertainty in the SSM $^8$B flux impedes a determination of the sterile neutrino fraction.Comment: Version to appear in PRL; includes analysis with anticipated SNO NC measuremen
