Kinetics of the reactions of isoprene-derived hydroxynitrates: gas phase epoxide formation and solution phase hydrolysis
Authors: Jacobs M. I. , Burke W. J. , Elrod M. J.
Published: September 2014

Abstract. Isoprene, the most abundant non-methane volatile organic compound (VOC) emitted into the atmosphere, is known to undergo gas phase oxidation to form eight different hydroxynitrate isomers in "high-NOx" environments. These hydroxynitrates are known to affect the global and regional formation of ozone and secondary organic aerosol (SOA), as well as affect the distribution of nitrogen. In the present study, we have synthesized three of the eight possible hydroxynitrates: 4-hydroxy-3-nitroxy isoprene (4,3-HNI) and E / Z-1-hydroxy-4-nitroxy isoprene (1,4-HNI). Oxidation of the 4,3-HNI isomer by the OH radical was monitored using a flow tube chemical ionization mass spectrometer (FT-CIMS), and its OH rate constant was determined to be (3.64 ± 0.41) × 10−11 cm3 molecule−1 s−1. The products of 4,3-HNI oxidation were monitored, and a mechanism to explain the products was developed. An isoprene epoxide (IEPOX) – a species important in SOA chemistry and thought to originate only from "low-NOx" isoprene oxidation – was found as a minor, but significant, product. Additionally, hydrolysis kinetics of the three synthesized isomers were monitored with nuclear magnetic resonance (NMR). The bulk, neutral solution hydrolysis rate constants for 4,3-HNI and the 1,4-HNI isomers were (1.59 ± 0.03) × 10−5 s−1 and (6.76 ± 0.09) × 10−3 s−1, respectively. The hydrolysis reactions of each isomer were found to be general acid-catalyzed. The reaction pathways, product yields and atmospheric implications for both the gas phase and aerosol phase reactions are discussed.

Published: September 2014

Abstract. The Mediterranean and Black seas are unique marine environments subject to important anthropogenic pressures due to direct and indirect loads of atmospheric inputs of organochlorine compounds (OCls) from primary and secondary sources. Here we report the results obtained during two east–west sampling cruises in June 2006 and May 2007 from Barcelona to Istanbul and Alexandria, respectively, where gas-phase and aerosol-phase samples were collected. Both matrices were analyzed for 41 polychlorinated biphenyls (PCBs), including dioxin-like congeners, and hexachlorobenzene (HCB). The values reported in this study for gas-phase HCB and ∑41PCB limit of detection (LOD) to 418.3 pg m−3 and from 81.99 to 931.6 pg m−3 respectively) are in the same range of those reported in former studies, possibly suggesting a limited decline in their atmospheric concentrations during the last decade for the Mediterranean region due to land-based OCl sources. There is a clear influence of the direction of the air mass on the atmospheric concentrations of PCBs, with higher concentrations when the air mass was from southern Europe, and the lowest concentrations for air masses coming from the SW Mediterranean and Atlantic Ocean. PCBs and HCB are close to air–water equilibrium for most sampling periods, thus resulting in low atmospheric deposition fluxes at open sea. This is consistent with the oligotrophic character of the Mediterranean Sea with a small influence of the biological pump capturing atmospheric PCBs. Therefore, degradation of gas-phase PCBs by OH radicals is estimated to be the main loss process of atmospheric PCBs during their transport over the Mediterranean Sea. Conversely, atmospheric residence times of HCB are predicted to be very long due to a lack of atmospheric degradation and low depositional fluxes due to concentrations at air–water equilibrium.
Relative impact of insolation and the Indo-Pacific warm pool surface temperature on the East Asia summer monsoon during the MIS-13 interglacial

Published: September 2014

Abstract. During Marine Isotope Stage (MIS)-13, an interglacial about 500 000 years ago, the East Asian summer monsoon (EASM) was suggested exceptionally strong by different proxies in China. However, MIS-13 is a weak interglacial in marine oxygen isotope records and has relatively low CO2 and CH4 concentrations compared to other interglacials of the last 800 000 years. In the meantime, the sea surface temperature (SST) reconstructions have shown that the warm pool was relatively warm during MIS-13. Based on climate modeling experiments, this study aims at investigating whether a warmer Indo-Pacific warm pool (IPWP) can explain the exceptionally strong EASM occurring during the relatively cool interglacial MIS-13. The relative contributions of insolation and of the IPWP SST as well as their synergism are quantified through experiments with the Hadley Centre atmosphere model, HadAM3, and using the factor separation technique. The SST of the IPWP has been increased based on geological reconstructions. Our results show that the pure impact of a strong summer insolation contributes to strengthen significantly the summer precipitation in northern China but only little in southern China. The pure impact of enhanced IPWP SST reduces, slightly, the summer precipitation in both northern and southern China. However, the synergism between insolation and enhanced IPWP SST contributes to a large increase of summer precipitation in southern China but to a slight decrease in northern China. Therefore, the ultimate role of enhanced IPWP SST is to reinforce the impact of insolation in southern China but reduce its impact in northern China. We conclude that a warmer IPWP helps to explain the strong MIS-13 EASM precipitation in southern China as recorded in proxy data, but another explanation is needed for northern China.

Abstract. The main part of the Cluster Spatio-Temporal Analysis of Field Fluctuations (STAFF) experiment consists of triaxial search coils allowing the measurements of the three magnetic components of the waves from 0.1 Hz up to 4 kHz. Two sets of data are produced, one by a module to filter and transmit the corresponding waveform up to either 10 or 180 Hz (STAFF-SC), and the second by the onboard Spectrum Analyser (STAFF-SA) to compute the elements of the spectral matrix for five components of the waves, 3 × B and 2 × E (from the EFW experiment), in the frequency range 8 Hz to 4 kHz. In order to understand the way the output signals of the search coils are calibrated, the transfer functions of the different parts of the instrument are described as well as the way to transform telemetry data into physical units across various coordinate systems from the spinning sensors to a fixed and known frame. The instrument sensitivity is discussed. Cross-calibration inside STAFF (SC and SA) is presented. Results of cross-calibration between the STAFF search coils and the Cluster Fluxgate Magnetometer (FGM) data are discussed. It is shown that these cross-calibrations lead to an agreement between both data sets at low frequency within a 2% error. By means of statistics done over 10 yr, it is shown that the functionalities and characteristics of both instruments have not changed during this period.
Estimating model error covariance matrix parameters in extended Kalman filtering
Authors: Solonen A. , Hakkarainen J. , Ilin A. , Abbas M. , Bibov A.
Published: September 2014

Abstract. The extended Kalman filter (EKF) is a popular state estimation method for nonlinear dynamical models. The model error covariance matrix is often seen as a tuning parameter in EKF, which is often simply postulated by the user. In this paper, we study the filter likelihood technique for estimating the parameters of the model error covariance matrix. The approach is based on computing the likelihood of the covariance matrix parameters using the filtering output. We show that (a) the importance of the model error covariance matrix calibration depends on the quality of the observations, and that (b) the estimation approach yields a well-tuned EKF in terms of the accuracy of the state estimates and model predictions. For our numerical experiments, we use the two-layer quasi-geostrophic model that is often used as a benchmark model for numerical weather prediction.
Sedimentological characteristics of ice-wedge polygon terrain in Adventdalen (Svalbard) – environmental and climatic implications for the late Holocene

Published: September 2014

Abstract. Ice wedges are widespread periglacial features in the landscape of Adventdalen, Svalbard. The networks of ice wedges have created areas with well-developed polygonal terrains in the lowest fluvial terraces in this valley. We have examined the sedimentological characteristics of the northern and southern banks of the Advent river for palaeoenvironmental purposes. The base of two sedimentary sections reported radiocarbon dates of 3.3 and 3.9 ka BP, respectively. The northern site is constituted by three very different lithostratigraphical units, which suggests that their formation should be related to different environmental and climate conditions. By contrast, the southern section shows a rather homogeneous composition, with no significant variations in grain size and organic matter content. In both cases the uppermost sediments are constituted by a thick aeolian deposit. According to our data, warmer climate conditions may have prevailed during the mid Holocene until 3.3 ka BP with widespread peat formation in the valley bottom. Subsequently, a period with alternating soil formation and aeolian sedimentation took place from 3 to 2.5 ka BP, probably due to increasing climatic severity. During the last millennium a long-term cooling trend has favoured aeolian deposition in the lowest part of Adventdalen.
AVALIAÇÃO DE EQUIDADE AMBIENTAL: UM DEVER FUNDAMENTAL SOCIOAMBIENTAL
Authors: Rammê Rogério Santos
Published: September 2014

O presente artigo objetiva, num primeiro momento, demonstrar a desconexão existente entre o atual projeto jurídico-constitucional socioambiental brasileiro e a realidade prática que, por diversos fatores e influências, vem impondo uma lógica de flexibilização e desconstrução da proteção jurídica do meio ambiente no Brasil. Num segundo momento, o objetivo é analisar, a partir de casos concretos, um dos principais fatores que contribuem para a crise socioambiental brasileira: o modelo equivocado de avaliação dos projetos de significativo impacto socioambiental, incapaz de avaliar adequadamente a distribuição dos potenciais impactos e riscos ambientais no cenário social dos atingidos. A partir do estudo realizado, conclui-se pela necessidade de reconhecer, na avaliação de equidade ambiental, um dever fundamental socioambiental, dotado de tipicidade própria, que consiste na exigibilidade de que os estudos de impacto ambiental incorporem critérios metodológicos capazes de melhor aferir a distribuição social dos impactos ambientais significativos dos projetos avaliados. Adotou-se o método dialético de abordagem, a partir de aportes doutrinários.

MULTIVARIATE MATHEMATICAL MORPHOLOGY FOR DCE-MRI IMAGE ANALYSIS IN ANGIOGENESIS STUDIES
Authors: Noyel Guillaume , Angulo Jesus , Jeulin Dominique , Balvay Daniel , Cuenod Charles-André
Published: September 2014

We propose a new computer aided detection framework for tumours acquired on DCE-MRI (Dynamic Contrast Enhanced Magnetic Resonance Imaging) series on small animals. To perform this approach, we consider DCE-MRI series as multivariate images. A full multivariate segmentation method based on dimensionality reduction, noise filtering, supervised classification and stochastic watershed is explained and tested on several data sets. The two main key-points introduced in this paper are noise reduction preserving contours and spatio temporal segmentation by stochastic watershed. Noise reduction is performed in a special way to select factorial axes of Factor Correspondence Analysis in order to preserves contours. Then a spatio-temporal approach based on stochastic watershed is used to segment tumours. The results obtained are in accordance with the diagnosis of the medical doctors.
ESTIMATION OF MINKOWSKI TENSORS FROM DIGITAL GREY-SCALE IMAGES
Authors: Svane Anne Marie
Published: September 2014

It was shown in Svane (2014b) that local algorithms based on grey-scale images sometimes lead to asymptotically unbiased estimators for surface area and integrated mean curvature. This paper extends the results to estimators for Minkowski tensors. In particular, asymptotically unbiased local algorithms for estimation of all volume and surface tensors and certain mean curvature tensors are given. This requires an extension of the asymptotic formulas of Svane (2014b) to estimators with position dependent weights.
MULTISCALE IMAGE ANALYSIS BASED ON ROBUST AND ADAPTIVE MORPHOLOGICAL SCALE-SPACES
Authors: Diop El Hadji Samba , Angulo Jesus
Published: September 2014

Mathematical morphology is a powerful tool for image analysis; however, classical morphological operators suffer from lacks of robustness against noise, and also intrinsic image features are not accounted at all in the process. We propose in this work a new and different way to overcome such limits, by introducing both robustness and locally adaptability in morphological operators, which are now defined in a manner such that intrinsic image features are accounted. Dealing with partial differential equations (PDEs) for generalized Cauchy problems, we show that proposed PDEs are equivalent to impose robustness and adaptability of corresponding sup-inf operators, to structuring functions. Accurate numerical schemes are also provided to solve proposed PDEs, and experiments conducted for both synthetic and real images, show the efficiency and robustness of our approach.
Bronchoscopy in Immediate Diagnosis of Smear Negative Tuberculosis
Authors: Kumar Raj , Singh Mandeep , Gupta Nitesh , Goel Nitin
Published: September 2014

Background: Tuberculosis is a major public health problem. Almost 30% of cases of tuberculosis are known to be sputum smear negative. There is a diagnostic dilemma in such cases leading to inadvertent delays in management of these cases. The present study was planned to assess the role of bronchoscopy in immediate diagnosis of smear negative pulmonary tuberculosis. Material and Methods: The present study is a retrospective analysis of 132 sputum smear negative tuberculosis suspects who underwent bronchoscopic evaluation during the period 2002–2013. The diagnosis of tuberculosis was based on the finding of bacilli in aspirate or in tissue biopsy or the demonstration of caseous necrosis on tissue biopsy. Results: The present study showed that bronchoscopy could lead to immediate, accurate diagnosis in 68.2% of suspected smear negative cases. Bronchial aspirate and bronchoalveolar lavage alone were diagnostic in 51.5% of such cases while tissue biopsy added to the yield in another 16.5% cases. Conclusions: The results of the present study suggests an important place of bronchoscopy in immediate diagnosis of suspected smear negative tuberculosis, thus avoiding inadvertent delays in diagnosing and instituting appropriate treatment.

Immediate Hypersensitivity Reaction with Mango
Authors: Shah Ashok , Gera Kamal
Published: September 2014

Hypersensitivity to the fruit mango is extremely rare and can exhibit either as immediate or delayed reactions. Since 1939, only 22 patients (10 with immediate type I reactions and 12 with delayed) have been documented with allergy to mango. History of atopy and geographical region may influence the type of reaction. Immediate reactions occured most often in patients with history of atopy, while delayed reactions developed in non-atopic individuals. Clustering of delayed hypersensitivity reports from Australia and immediate reactions from Europe has been documented. We report a 50-year-old man with immediate type I hypersensitivity to mango, who developed cough, wheezing dyspnoea, generalised itching and abdominal discomfort after ingestion of mango. Life threatening event can also happen making it imperative to diagnose on time, so as to prevent significant morbidity and potential mortality

Published: September 2014

We present a case of a 57-year-old woman suffering from granulomatosis with polyangiitis (GPA), who in the seventh months of immunosuppressive treatment (cyclophosphamide) progressed with new pulmonary changes and perforations of the hard palate and bronchi. Rituximab was introduced resulting in B-cell depletion and disappearance of anti-PR3 antibody. Palatal holes have substantially diminished and all bronchial perforations disappeared, covered by fibrous tissue. In the fourth month after rituximab administration, large scarring obstruction of the right main bronchus with upper and middle lobes atelectasis emerged. Because of increasing dyspnoea, stenotic bronchus was re-opened by bronchoscopy. Intervention was complicated by bilateral pneumothorax and later, on the seventh day, by fatal pulmonary bleeding. To our knowledge, this is the first report of GPA refractory to cyclophosphamide complicated by palatal and bronchial perforations.
Pneumocystozowe Zapalenie Płuc u Zakażonych HIV Przy Współistniejącym Zakażeniu Cytomegalowirusem. Opis Dwóch Przypadków i Przegląd Literatury

Published: September 2014

Pneumocystozowe zapalenie płuc (PCP) jest jedną z wielu infekcyjnych chorób układu oddechowego u zakażonych HIV wywoływaną przez patogen Pneumocystis jiroveci, zaliczany do grzybów. Pneumocystoza jest od ponad 30 lat najczęstszą chorobą wskaźnikową zespołu nabytego niedoboru odporności (AIDS). Najważniejszym czynnikiem ryzyka rozwoju PCP jest obniżenie liczby limfocytów T CD4+ poniżej 200 komórek/mcL. Objawy kliniczne choroby to: przewlekły kaszel, duszność i osłabienie. W badaniu gazometrycznym krwi tętniczej lub arterializowanej krwi kapilarnej często stwierdza się hipoksemię, a w tomografii komputerowej o wysokiej rozdzielczości — obraz matowej szyby. Leczeniem z wyboru jest parenteralne podawanie trimetoprimu z sulfametoksazolem, U chorych w średnim i ciężkim stanie zaleca się systemowe podawanie glikokortykosteroidów. Współistnienie zakażenia wirusem cytomegalii (CMV) pogarsza rokowanie chorych. Narządowego zajęcia w przebiegu zakażenia CMV należy poszukiwać u chorych z liczbą komórek T CD4+ poniżej 50/mcL. Kwestią sporną pozostaje leczenie zakażenia CMV u chorych z rozpoznanym PCP. Uważa się, że w większości przypadków zakażenie CMV pozostaje bezobjawowe. Glikokortykosteroidy podawane w przypadkach PCP o cięższym przebiegu mogą pogarszać rokowanie i promować rozwój objawowego cytomegalowirusowego zapalenia płuc. W pracy przedstawiono dwa przypadki PCP, które były pierwszym objawem zakażenia HIV. W obu udowodniono również zakażenie CMV.
A Cooperative Path Planning Algorithm for a Multiple Mobile Robot System in a Dynamic Environment
Authors: Yu Wentao , Peng Jun , Zhang Xiaoyong , Lin Kuo-Chi
Published: September 2014

A practical path planning method for a multiple mobile robot system (MMRS) requires handling both the collision-free constraint and the kinematic constraint of real robots, the latter of which has to date been neglected by most path planning methods. In this paper, we present a practical cooperative path planning algorithm for MMRS in a dynamic environment. First, each robot uses an analytical method to plan an obstacle-avoidance path. Then, a distributed prioritized scheme is introduced to realize cooperative path planning. In the scheme, each robot calculates a priority value according to its situation at each instant in time, which will determine the robot's priority. Higher-priority robots can ignore lower-priority robots, whereas lower-priority robots should avoid collisions with higher-priority robots. To minimize the path length for MMRS, a least path length constraint is added. The priority value is also calculated by a path cost function that takes the path length into consideration. Unlike other priority methods, the algorithm proposed is not time consuming; therefore, it is suitable for dynamic environments. Simulation results are presented to verify the effectiveness of the proposed algorithm.
Adaptive Multi-Sensor Perception for Driving Automation in Outdoor Contexts
Authors: Milella Annalisa , Reina Giulio
Published: September 2014

In this research, adaptive perception for driving automation is discussed so as to enable a vehicle to automatically detect driveable areas and obstacles in the scene. It is especially designed for outdoor contexts where conventional perception systems that rely on a priori knowledge of the terrain's geometric properties, appearance properties, or both, is prone to fail, due to the variability in the terrain properties and environmental conditions. In contrast, the proposed framework uses a self-learning approach to build a model of the ground class that is continuously adjusted online to reflect the latest ground appearance. The system also features high flexibility, as it can work using a single sensor modality or a multi-sensor combination. In the context of this research, different embodiments have been demonstrated using range data coming from either a radar or a stereo camera, and adopting self-supervised strategies where monocular vision is automatically trained by radar or stereo vision. A comprehensive set of experimental results, obtained with different ground vehicles operating in the field, are presented to validate and assess the performance of the system.

Published: September 2014

O presente trabalho tem o objetivo de abordar a formação da agenda política que deu origem à reforma da educação implementada através do decreto 2208 de 1997. Para tanto utiliza a divisão trazida pelo artigo “Os três ciclos da sociedade brasileira” de Bresser-Pereira, como base para justificar a forma que o processo de criação e implementação de políticas públicas na área da educação profissional assumiu no país. O pacto liberal- dependente que vigorou durante a década de 1980 e 1990 no Brasil e a reestruturação produtiva capitalista que trouxe o conceito de flexibilidade para as relações de trabalho e para os processos produtivos servem de suporte para entender o interesse e a influência de organismos internacionais na definição das políticas públicas no Brasil, nessa área. Os motivos, a natureza e os efeitos dessa política são tratados no artigo, bem como os novos rumos que a educação profissional tomou com a mudança de governo em 2003.

The more you know, is it better? School and sexual and reproductive health
Authors: Seidmann Susana , Di Iorio Jorgelina , Azzollini Susana , Rolando Silvana
Published: September 2014

The ratification of the Law 26.150 in Argentina, in the year 2006, established the National Program of Integral Sexual Education, by which all children at school “have the right to receive integral sexual education at public schools, in state or private institutions,  in national, province, Autonomous City of Buenos Aires and city´ s territories”. Sexual education appears as a “new” content in a scholar structure that has to suit its teaching practices to demands perceived as external and imposed. In the frame of a research about social representations of teaching practices, there appeared some difficulties and tensions at schools related to the teaching of the contents of sexual integral education. 21 depth interviews with teachers were accomplished in the City of Buenos Aires´, Argentina, high schools. The main thematic axes were the teaching practices related to sexual integral education, the obstacles and opportunities of sexual integral education. Through emergent categories, the material was analyzed through the comparative constant method. The teaching practices are organized as a complex and heterogeneous interaction field, in which teachers´ everyday life develops, which permits to define school as a place of meaning negotiation. It is important to think about teaching practice because it permits to clear up ideas and assumptions which work as an efficacy condition of the scholar device.

Published: September 2014

O presente texto discute o lugar da Pedagogia na universidade e a promoção da qualidade do ensino, no quadro de políticas atuais de reforma do Ensino Superior provenientes do Processo de Bolonha. Entende-se que tais políticas também influenciam as políticas públicas no Brasil e apresentam-se elementos teórico-metodológicos facilitadores para futura análise nesse contexto. Com a finalidade de compreender o impacto do Processo de Bolonha no âmbito da inovação e da supervisão da ação docente, realizou-se uma pesquisa exploratória em Portugal, a partir de entrevistas a seis gestores pedagógicos de cursos de Engenharia de três universidades públicas. Conclui-se que a inovação e a supervisão se movem num terreno em transição, incorporando lógicas contraditórias de algum modo decorrentes de tensões inerentes às mudanças em curso, mas no qual podemos entrever sinais de construção de uma cultura pedagógica mais refletida e coletivizada, potencialmente instigadora da reconfiguração da profissionalidade docente no meio académico.

O presente artigo objetiva analisar a formação de professores para a Educação Superior e suas relações com a diversidade da docência como prática profissional. O tema vem sendo, paulatinamente, questionado no debate e na prática pedagógica ética e institucional. A docência na Educação Superior é um empreendimento que articula diferentes possibilidades e exige formação pedagógica. Realizo uma breve leitura dos termos formação e docência e apresento um argumento em favor da natureza e das características da docência, deixando transparecer a questão de sua diversidade. Para propor um ponto departida para o processo formativo, escolhi seis facetas da docência que deram origem a este artigo, a partir de observações realizadas em aulas de cursos de graduação na área de Saúde. Concluo defendendo a tentativa de construção de alguns princípios formativos, tais como: a docência representa um amálgama marcado pelas políticas públicas, considera adiversidade, é prática social contextualizada
O PIBID como “terceiro espaço” de formação inicial de professores
Authors: Dos Santos Felício Helena Maria
Published: September 2014

Este trabalho visa analisar a percepção dos licenciandos envolvidos no ProgramaInstitucional de Bolsa de Iniciação à Docência (PIBID), na Universidade Federal de Alfenas (UNIFAL-MG), referente ao desenvolvimento de tal programa como um espaçotempo para a formação docente. Zeichner (2010) estrutura o conceito de terceiro espaço, rejeitando as polaridades entre teoria e prática na formação de professores em prol da elaboração de espaçostempos que reúnam o conhecimento prático ao acadêmico de modos menos hierárquicos, tendo em vista a criação de novas oportunidades de aprendizagem para professores em formação inicial. A partir desse conceito, realizamos a análise qualitativa dos significados do PIBID, construídos pelos licenciandos bolsistas no triênio 2010-2012, a dos pressupostos metodológicos dos estudos das narrativas. Para tanto, estabelecemos como categorias as informações sobre relação teoria-prática, relação Universidade-Escola, realidade educacional e escolar, formação inicial e continuada da docência. Os resultados apontam para a necessidade de o PIBID, como política pública de formação inicial de professores, provocar ações nas políticas de carreira docente e nas políticas definidoras de condições do trabalho docente, uma vez que, para os licenciandos, apesar de o PIBID se constituir como um espaçotempo fundamental para consolidação de uma formação docente de qualidade, o Ensino Superior se configura o nível almejado por eles para o exercício da docência.
Formação docente, valores éticos e cultura das mídias digitais: referenciais das práticas de professores para a escola contemporânea
Authors: De Campos Hagemeyer Regina Cely
Published: September 2014

Este artigo analisa as mudanças das práticas de professores diante dos processos culturais gerados pelas programações das mídias digitais, que agenciam as identidades dos estudantes da escola contemporânea. Para tanto, contextualiza-se o cenário cultural atual, retomando as noções de sujeito, identidade/subjetividade e ética de Giroux, Costa, Hall e Bauman. Os processos das práticas docentes são discutidos com base na pesquisa de Hagemeyer sobre professores catalisadores, definidos como aqueles que compreendem os novos interesses e as necessidades dos estudantes e os agregam a suas práticas na escola atual. A percepção dos professores sobre as influências da cultura das mídias digitais nas motivações de crianças e jovens escolares os tem levado a modificar estratégias e atitudes para a construção de valores éticos em suas aulas, processos que serão identificados e analisados como contribuições às mudanças necessárias a essa formação. Propõe-se comparar as pesquisas realizadas de 2006 a 2008 com pesquisas similares mais recentes (2009–2012), as análises sobre as práticas e os depoimentos de professores catalisadores, diante da evolução das mídias digitais e o impacto sobre as mudanças de valores de crianças e jovens escolares. As disposições e práticas dos professores indicaram avanços e procedimentos voltados a atitudes éticas e de direitos humanos, além de revelar maior proximidade à cultura digital dos estudantes. Os pontos comuns entre os dois grupos levaram à identificação de referenciais sobre a formação de valores ético-sociais nas práticas pedagógicas, contribuindo com a formação docente inicial e continuada nessa perspectiva.

Published: September 2014

O presente estudo, de orientação bibliográfica, pesquisa teses, dissertações, artigos, legislações e documentos oficiais com a intenção de apresentar alguns aspectos que traduzem a organização pedagógica do Ensino Religioso na Amazônia brasileira, a partir da nova concepção dada à disciplina com a alteração do art. 33, da LDBEN/1996, por meio da Lei n. 9.475/1997. Para isso, recorre-se à visita em websites das secretarias estaduais e municipais de Educação, dos CEEs e CMEs, assim como das instituições e grupos de pesquisas envolvidos com a disciplina para localizar parte dessas produções e documentos. Diante dos dados e das informações encontrados podemos perceber que o Ensino Religioso possui certo status como área de conhecimento, organizado a partir dos sistemas de ensino e de sua área própria, as Ciências da Religião,assumida como referencial para a formação de professores e modelo para a prática pedagógica, presente nas propostas curriculares localizadas e nos editais dos concursos públicos na Região Norte.
Religião e educação, um diálogo emergente: do teórico ao prático para constituição de uma área de conhecimento [I]
Authors: Pereira Figueira Eulálio Avelino
Published: September 2014

Este artigo tem por objeto o Ensino Religioso na sala de aula, visto como disciplina curricular, e apresenta o que podem ser observados como elementos constituintes para uma epistemologia que subsidie uma área de conhecimento de forma a abordar o fenômeno religioso em chave pedagógica. Tivemos a preocupação de tratar da Religião enquanto processo de educação que se coloca além do debate de domínio confessional. Assumimos que será por uma postura pedagógica que a religião, uma das atividades definidoras do homem contemporâneo, deverá ser abordada para assim chegarmos ao entendimento sobre boa parte dos dados constituintes das relações humanas produzidas na pluralidade das sociedades contemporâneas, marcadas pela peculiaridade da laicidade e de seu contexto originário, definido como secularização. Para atendermos a este desafio e proposta adotamos a postura crítica/ pragmática subsidiada pelo pensamento de Richard Rorty e articulada à proposta de uma Teologia Pública pós-metafísica. A atividade do educar, mais do que assumir a transmissão e informação sobre conteúdos, precisa tratar dos diversos e plurais lugares, como também das linguagens de produção e desenvolvimento desse conhecimento que identifica a peculiaridade da existência humana. Diante da necessidade pragmática e até muitas vezes de um sentido fortemente utilitarista, a emergência de uma visão simbólica, e por que não se dizer mistérica das capacidades e habilidades que devem estar presentes nas ações humanas para enfrentar o mundo com o qual somos confrontados, é matéria que não fica fora de suas preocupações. Mas deve a educação se constituir de “ferramentas” apropriadas para poder desempenhar com satisfação essa tarefa.
Spiritual learning communities: historical, systematic and practical observations1
Authors: Roebben Bert
Published: September 2014

Children and young people have the inalienable right to be part of a learning community. Nobody can learn on his/her own. Education is always a communal enterprise. In this paper the concept of the ‘spiritual learning community’ is developed as a contemporary answer to the socio-educational issues raised by Martin Buber and John Dewey in the 1930s. Cultural and religious diversity today stimulate education and schooling more than ever before to reconsider the narrative-communicative and spiritual dimension of every learning process. The spiritual dimension of the learning community relates to a specifichabitus, namely of de-centration from the self and dedication to the other, and to a specific focus, namely on existential questions such as content of the learning process. Insightsfrom philosophy of education and from European religious education theory and concrete experiences of teacher education at the universities of Dortmund (Germany) and Wien(Austria) form the horizon for this reflection.
Pluralismo e alteridade: o lugar que os segmentos [T] LGBTTTI ocupam no currículo da disciplina de Ensino Religioso nas escolas estaduais e municipais de Recife (PE)
Authors: De Oliveira Aurenéa Maria
Published: September 2014

A disciplina de Ensino Religioso (ER), com oferta “garantida” nas escolas públicas pela atual LDB de 1996, apresenta em sua concepção/reconfiguração atual conteúdos programáticos emblemáticos/fronteiriços e enviesados que servem como campo de investigação cultural acerca do entendimento de lugares que segmentos socialmente marginalizados ocupam dentro de cosmologias religiosas circulantes no Brasil. Assim, por meio do currículo e dos componentes ministrados nesta disciplina, podemos analisar e questionar demarcações feitas em torno de posições inferiores e/ou não que grupos como o LGBTTTI, por exemplo, possuem, especialmente quando essas demarcações implicarem estímulo a práticas de domesticação, estigmatização, intolerância e violência, isso como reflexo de perspectivas homofóbicas e/ou, por outro lado, quando essas delimitações implicarem respeito às diferenças e diversidade sexual com promoção de subversão a posturas e relações heteronormativas. Neste caso, este é o principal foco de investigação desta pesquisa, realizada em escolas estaduais e municipais de Recife (PE) com financiamento da Fundação de Amparo à Ciência e Tecnologia do Estado de Pernambuco (Facepe), e este foco será examinado numa perspectiva pós-estruturalista.
The demand for competencies in spiritual care in nursing and midwifery education: a literature review
Authors: Attard Josephine , Baldacchino Donia
Published: September 2014

Spirituality is embedded in nursing and midwifery practice and within the role of nurses and midwives. As a result, spirituality is an important element in nursing and midwifery education and practice, an area which has largely been ignored, in spite of the constant call of Professional Bodies for spiritual care competence in the provision of holistic care. This review aimed to analyze the existing literature and research to define competency and identify the key issues around the demand for competencies and education in spiritual care in nursing and midwifery. A search for articles in English was carried out using various search engines, using keywords: ‘competence, competency, definition, nursing, midwifery practice’. The findings showed that consensus on the definition of competency is still inconsistent. The majority of literature acknowledges the dimensions of knowledge, skills and attitudes which support the three components in Bloom’s Taxonomy namely, the cognitive, affective and psychomotor domains. Competence in spiritual care is guided by Benner’s theory: From novice to expert. Key issues were identified explaining the demand for competence in spiritual care such as, the complexity of spirituality and spiritual care which requires formal integration of spiritual care within the curricula by incorporating both the ‘taught’ and ‘caught’ perspectives of teaching and learning. Assessment of competence in nursing/midwifery education demands the formulation of generic and specific competencies oriented towards knowledge, skills and attitudes towards spiritual care. Thus, further research is suggested to develop a framework of competencies to be achieved by undergraduate and postgraduate students.
Mistagogia: um diálogo fecundo [T] entre mística e pedagogia
Authors: Da Costa Rosemary Fernandes
Published: September 2014

As ações evangelizadoras em suas experiências de iniciação, formação e orientação vem sendo matéria-prima de estudos, reflexão e avaliação. Mais do que buscar novas metodologias que dialoguem com o nosso tempo, a mistagogia nos fala de uma fundamentação antropológica e teológica que resgata sua essência e aponta caminhos pastorais. A experiência mistagógica vivida nos séculos III e IV, especialmente com Cirilo de Jerusalém, torna-se fontal e orientadora de categorias que dialogam com as comunidades contemporâneas. A crise da fé nos reclama um novo caminho místico, uma espiritualidade integradora. Pede-nos urgência de uma revisão profunda dos processos de orientação religiosa, da vitalidade das comunidades e do modo concreto de viver a relação religião-mundo e fé-cultura. A partir do processo de elaboração entre a teologia sistemática e o resgate dessa experiência fontal, apresentamos algumas contribuições que podem se tornar mais do que memória viva para nosso presente, mas sementes fecundas nos processos de evangelização atuais.
Nuclear envelope protein MAN1 regulates clock through BMAL1

Published: September 2014

Circadian clocks serve as internal pacemakers that influence many basic homeostatic processes; consequently, the expression and function of their components are tightly regulated by intricate networks of feedback loops that fine-tune circadian processes. Our knowledge of these components and pathways is far from exhaustive. In recent decades, the nuclear envelope has emerged as a global gene regulatory machine, although its role in circadian regulation has not been explored. We report that transcription of the core clock component BMAL1 is positively modulated by the inner nuclear membrane protein MAN1, which directly binds the BMAL1 promoter and enhances its transcription. Our results establish a novel connection between the nuclear periphery and circadian rhythmicity, therefore bridging two global regulatory systems that modulate all aspects of bodily functions.
Common intermediates and kinetics, but different energetics, in the assembly of SNARE proteins

Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) are evolutionarily conserved machines that couple their folding/assembly to membrane fusion. However, it is unclear how these processes are regulated and function. To determine these mechanisms, we characterized the folding energy and kinetics of four representative SNARE complexes at a single-molecule level using high-resolution optical tweezers. We found that all SNARE complexes assemble by the same step-wise zippering mechanism: slow N-terminal domain (NTD) association, a pause in a force-dependent half-zippered intermediate, and fast C-terminal domain (CTD) zippering. The energy release from CTD zippering differs for yeast (13 kBT) and neuronal SNARE complexes (27 kBT), and is concentrated at the C-terminal part of CTD zippering. Thus, SNARE complexes share a conserved zippering pathway and polarized energy release to efficiently drive membrane fusion, but generate different amounts of zippering energy to regulate fusion kinetics.
Cross-synaptic synchrony and transmission of signal and noise across the mouse retina

Published: September 2014

Cross-synaptic synchrony—correlations in transmitter release across output synapses of a single neuron—is a key determinant of how signal and noise traverse neural circuits. The anatomical connectivity between rod bipolar and A17 amacrine cells in the mammalian retina, specifically that neighboring A17s often receive input from many of the same rod bipolar cells, provides a rare technical opportunity to measure cross-synaptic synchrony under physiological conditions. This approach reveals that synchronization of rod bipolar cell synapses is near perfect in the dark and decreases with increasing light level. Strong synaptic synchronization in the dark minimizes intrinsic synaptic noise and allows rod bipolar cells to faithfully transmit upstream signal and noise to downstream neurons. Desynchronization in steady light lowers the sensitivity of the rod bipolar output to upstream voltage fluctuations. This work reveals how cross-synaptic synchrony shapes retinal responses to physiological light inputs and, more generally, signaling in complex neural networks.
