A formação do pesquisador na pós-graduação em educação na universidade moderna: valores epistemológicos e ético-políticos

Objetivou-se compreender o horizonte axiológico da Universidade Moderna nas suas repercussões na formação do pesquisador em educação no Programa de Pós-Graduação em Educação (PPGED) da Universidade Federal do Pará (UFPA). O Problema de pesquisa expressa-se em duas interrogações: 1) Quais valores epistemológicos e ético-políticos da Universidade Moderna a UFPA incorpora ao seu ideal formativo? 2) Que valores apresentam se na formação do pesquisador no PPGED? Partiu-se de uma abordagem epistemológica, fundamentada na fenomenologia hermenêutica-existencial, que tomou os dados bibliográficos, as transcrições de entrevistas semi-estruturadas e as notas de campo como textos, em cuja organização lançou-se mão de técnicas de análise de conteúdo. Constatou-se que a ideia de universidade moderna, teve a sua origem na filosofia iluminista, que apesar de consagrar a noção de pesquisa como o seu centro, assentava-se, na verdade, no conceito de formação (Bildung), com inspiração no neo-humanismo. Mais do que o pesquisador stricto sensu, a universidade deve formar o homem que pensa por conta própria, autônomo, crítico e racional e é nisso que se encontra a essência do pesquisar. Pôde-se confirmar a tese proposta de acordo com a qual “O referencial ético-político e epistemológico da universidade moderna, baseado na noção de subjetividade autônoma, livre, consciente e crítica, mantém o seu vigor institucional na constituição do horizonte axiológico da formação na UFPA e no PPGED, em particular, embora esses valores venham sendo modalizados e criticados, em um movimento de autocrítica que é parte constitutiva do sujeito moderno.

A universalidade poética de Rilke na formação do Grupo dos Novos: tradução e confluências na Amazônia brasileira

Esta dissertação objetiva pensar os desdobramentos que as traduções da poesia de Rainer Maria Rilke alcançaram no cenário do Suplemento Literário da Folha do Norte - SL/FN e em outros periódicos das décadas de 1940 e 1950, em que foram publicadas. Consideramos que estas traduções foram um indício de intensificação da abertura universalizante das letras paraenses às novidades modernistas iniciadas na Semana de Arte Moderna de 1922. Tais traduções foram cruciais para a formação do Grupo dos Novos, composto principalmente de nomes como Benedito Nunes, Mário Faustino e Paulo Plinio Abreu, além do antropólogo alemão Peter Paul Hilbert. O suporte teórico-metodológico será a utilização dos conceitos de Weltliteratur (Literatura universal) de Goethe e Reflexionsmedium (Médium-de-reflexão) de Benjamin. Estas matrizes interligarão os campos da história, da filosofia da linguagem e da tradução para refletirmos sobre o impacto dessas traduções na Amazônia brasileira da época. Outro conceito importante nesta dissertação é o de Bildung (formação), pensado a partir da leitura de Antoine Berman quando ele o relaciona à tradução, incluindo vários fenômenos que envolvem as relações tradutórias entre culturas e línguas. Ao final, por meio da reflexão tradutológica de Haroldo de Campos, visamos observar possíveis confluências nas produções poéticas e críticas de Mário Faustino, Manuel Bandeira e Paulo Plínio Abreu, como resultante do processo relacional promovido por estas traduções.

O canto das Sereias e a embriaguez do tradutor

Sabemos que para os românticos alemães a tradução tem um caráter fundador, estando associada ao próprio conceito de Bildung, como já assinalava Antoine Berman. A Bildung remete necessariamente à dimensão da experiência, processo de desdobramento e alargamento que encontra uma metáfora perfeita na noção de viagem, tão cara aos românticos. Tal movimento de travessia que constitui a inquietante "tarefa do tradutor" pode ser entendido como uma navegação por essa região nebulosa onde se ouve o canto das Sereias e, como pensava Maurice Blanchot, corre-se o risco do desaparecimento.

A search for anisotropy in the arrival directions of ultra high energy cosmic rays recorded at the Pierre Auger Observatory

Observations of cosmic rays arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra high energy cosmic rays (UHECRs) with objects drawn from the Veron-Cetty Veron catalog. In this paper we report on the use of three catalog independent methods to search for anisotropy. The 2pt-L, 2pt+ and 3pt methods, each giving a different measure of self-clustering in arrival directions, were tested on mock cosmic ray data sets to study the impacts of sample size and magnetic smearing on their results, accounting for both angular and energy resolutions. If the sources of UHECRs follow the same large scale structure as ordinary galaxies in the local Universe and if UHECRs are deflected no more than a few degrees, a study of mock maps suggests that these three method can efficiently respond to the resulting anisotropy with a P-value = 1.0% or smaller with data sets as few as 100 events. using data taken from January 1, 2004 to July 31, 2010 we examined the 20, 30, ... , 110 highest energy events with a corresponding minimum energy threshold of about 49.3 EeV. The minimum P-values found were 13.5% using the 2pt-L method, 1.0% using the 2pt+ method and 1.1% using the 3pt method for the highest 100 energy events. In view of the multiple (correlated) scans performed on the data set, these catalog-independent methods do not yield strong evidence of anisotropy in the highest energy cosmic rays.

Nuclear-modification factor for open-heavy-flavor production at forward rapidity in Cu plus Cu collisions at root s(NN)=200 GeV

Background: Heavy-flavor production in p + p collisions is a good test of perturbative-quantum-chromodynamics (pQCD) calculations. Modification of heavy-flavor production in heavy-ion collisions relative to binary-collision scaling from p + p results, quantified with the nuclear-modification factor (R-AA), provides information on both cold-and hot-nuclear-matter effects. Midrapidity heavy-flavor R-AA measurements at the Relativistic Heavy Ion Collider have challenged parton-energy-loss models and resulted in upper limits on the viscosity-entropy ratio that are near the quantum lower bound. Such measurements have not been made in the forward-rapidity region. Purpose: Determine transverse-momentum (p(T)) spectra and the corresponding R-AA for muons from heavy-flavor meson decay in p + p and Cu + Cu collisions at root s(NN) = 200 GeV and y = 1.65. Method: Results are obtained using the semileptonic decay of heavy-flavor mesons into negative muons. The PHENIX muon-arm spectrometers measure the p(T) spectra of inclusive muon candidates. Backgrounds, primarily due to light hadrons, are determined with a Monte Carlo calculation using a set of input hadron distributions tuned to match measured-hadron distributions in the same detector and statistically subtracted. Results: The charm-production cross section in p + p collisions at root s = 200 GeV, integrated over p(T) and in the rapidity range 1.4 < y < 1.9, is found to be d(sigma e (e) over bar)/dy = 0.139 +/- 0.029 (stat)(-0.058)(+0.051) (syst) mb. This result is consistent with a perturbative fixed-order-plus-next-to-leading-log calculation within scale uncertainties and is also consistent with expectations based on the corresponding midrapidity charm-production cross section measured by PHENIX. The R-AA for heavy-flavor muons in Cu + Cu collisions is measured in three centrality bins for 1 < p(T) < 4 GeV/c. Suppression relative to binary-collision scaling (R-AA < 1) increases with centrality. Conclusions: Within experimental and theoretical uncertainties, the measured charm yield in p + p collisions is consistent with state-of-the-art pQCD calculations. Suppression in central Cu + Cu collisions suggests the presence of significant cold-nuclear-matter effects and final-state energy loss.

Left ventricular thrombus attenuation characterization in cardiac computed tomography angiography

BACKGROUND: Because of their similar visual appearance, differentiation of left ventricular thrombotic material and myocardial wall can be difficult in contrast-enhanced coronary computed tomography (CT) angiography. OBJECTIVE: We identified typical thrombi attenuation of left ventricular thrombi with the use of CT measurement. METHODS: Over a time period of 6 years; we retrospectively identified 31 patients who showed a left ventricular thrombus in CT angiography datasets. Patients underwent routine contrast cardiac CT to investigate coronary artery disease. CT attenuation of each thrombus was assessed in the 4-chamber view. CT densities were also determined in the ascending aorta, left ventricle, and myocardial wall both in the mid-septal and mid-lateral segments. The mean CT attenuation of thrombi and the difference between attenuation in thrombi, left ventricular cavity, and myocardial wall were determined. The ratio of attenuation values in thrombus versus aorta and myocardium versus aorta were also determined. RESULTS: Mean (+/- SD) CT attenuation of all left ventricular thrombi in 31 patients was 43.2 +/- 15.3 HU (range, 25-80 HU). Mean CT densities of septal and lateral myocardial wall were 102.9 +/- 23.1 HU (range, 63-155 HU) and 99.3 +/- 28.7 HU (range, 72-191 HU), respectively, and were thus significantly higher than the CT attenuation of thrombi (P < 0.001). A threshold of 65 HU yielded a sensitivity, specificity, and positive and negative predictive values of 94%, 97%, 94%, and 97%, respectively, to differentiate thrombus from the myocardial wall. The mean ratio between CT attenuation of thrombus and CT attenuation within the ascending aorta was 0.11 +/- 0.05 (range, 0.04-0.23), which was significantly lower compared with the mean ratio between CT attenuation of the myocardial wall and the CT attenuation within the ascending aorta. CONCLUSION: CT attenuation within left ventricular thrombi was significantly lower than myocardial attenuation in CT angiography datasets. Assessment of CT attenuation may contribute to the differentiation of thrombi. (C) 2012 Society of Cardiovascular Computed Tomography. All rights reserved.

Description of atmospheric conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS)

Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargue and averaged monthly models, the utility of the GDAS data is shown. (C) 2012 Elsevier B.V.

The rapid atmospheric monitoring system of the Pierre Auger Observatory

The Pierre Auger Observatory is a facility built to detect air showers produced by cosmic rays above 10(17) eV. During clear nights with a low illuminated moon fraction, the UV fluorescence light produced by air showers is recorded by optical telescopes at the Observatory. To correct the observations for variations in atmospheric conditions, atmospheric monitoring is performed at regular intervals ranging from several minutes (for cloud identification) to several hours (for aerosol conditions) to several days (for vertical profiles of temperature, pressure, and humidity). In 2009, the monitoring program was upgraded to allow for additional targeted measurements of atmospheric conditions shortly after the detection of air showers of special interest, e. g., showers produced by very high-energy cosmic rays or showers with atypical longitudinal profiles. The former events are of particular importance for the determination of the energy scale of the Observatory, and the latter are characteristic of unusual air shower physics or exotic primary particle types. The purpose of targeted (or "rapid") monitoring is to improve the resolution of the atmospheric measurements for such events. In this paper, we report on the implementation of the rapid monitoring program and its current status. The rapid monitoring data have been analyzed and applied to the reconstruction of air showers of high interest, and indicate that the air fluorescence measurements affected by clouds and aerosols are effectively corrected using measurements from the regular atmospheric monitoring program. We find that the rapid monitoring program has potential for supporting dedicated physics analyses beyond the standard event reconstruction.

Evolution of pi(0) Suppression in Au plus Au Collisions from root s(NN)=39 to 200 GeV

Neutral-pion pi(0) spectra were measured at midrapidity (vertical bar y vertical bar < 0.35) in Au + Au collisions at root s(NN) = 39 and 62.4 GeV and compared with earlier measurements at 200 GeV in a transverse-momentum range of 1 < p(T) < 10 GeV/c. The high-p(T) tail is well described by a power law in all cases, and the powers decrease significantly with decreasing center-of-mass energy. The change of powers is very similar to that observed in the corresponding spectra for p + p collisions. The nuclear modification factors (RAA) show significant suppression, with a distinct energy, centrality, and p(T) dependence. Above p(T) = 7 GeV/c, R-AA is similar for root sNN = 62.4 and 200 GeV at all centralities. Perturbative-quantum-chromodynamics calculations that describe R-AA well at 200 GeV fail to describe the 39 GeV data, raising the possibility that, for the same p(T) region, the relative importance of initial-state effects and soft processes increases at lower energies. The p(T) range where pi(0) spectra in central Au + Au collisions have the same power as in p + p collisions is approximate to 5 and 7 GeV/c for root sNN = 200 and 62.4 GeV, respectively. For the root sNN = 39 GeV data, it is not clear whether such a region is reached, and the x(T) dependence of the x(T)-scaling power-law exponent is very different from that observed in the root sNN = 62 and 200 GeV data, providing further evidence that initial-state effects and soft processes mask the in-medium suppression of hardscattered partons to higher p(T) as the collision energy decreases.

Measurement of Direct Photons in Au plus Au Collisions at root s(NN)=200 GeV

We report the measurement of direct photons at midrapidity in Au + Au collisions at root s(NN) = 200 GeV. The direct photon signal was extracted for the transverse momentum range of 4 GeV/c < pT < 22 GeV/c, using a statistical method to subtract decay photons from the inclusive photon sample. The direct photon nuclear modification factor R-AA was calculated as a function of p(T) for different Au + Au collision centralities using the measured p + p direct photon spectrum and compared to theoretical predictions. R-AA was found to be consistent with unity for all centralities over the entire measured pT range. Theoretical models that account for modifications of initial direct photon production due to modified parton distribution functions in Au and the different isospin composition of the nuclei predict a modest change of R-AA from unity. They are consistent with the data. Models with compensating effects of the quark-gluon plasma on high-energy photons, such as suppression of jet-fragmentation photons and induced-photon bremsstrahlung from partons traversing the medium, are also consistent with this measurement.
