A Formação Continuada dos Professores e a Prática Pedagógica Mediada pelas Tecnologias
Authors: Battini Okçana , França Cyntia Simioni , Reis Sandra Regina 
Published: May 2016

<p>O contexto educacional atual requer a superação de modelos de formação clássicos, estruturados e padronizados que visam a atingir a todos igualmente. Partindo desse pressuposto, foi proposta uma investigação que teve como título: Professor Seu Lugar é Aqui: estudos sobre formação, trabalho e práticas pedagógicas no espaço escolar. A pesquisa foi realizada em três escolas públicas na cidade de Londrina, PR. A coleta foi realizada por meio de questionário, ao qual responderam setenta e seis professores. Buscou-se traduzir a visão desses docentes sobre a utilização dos recursos computacionais e da internet na sua prática pedagógica, frente às novas metodologias de trabalho. Também,<br />elencar as dificuldades encontradas durante o processo de formação continuada. As falas dos professores entrevistados apontaram para a necessidade de se estreitar o diálogo entre a universidade e a escola, por meio de proposta de formação continuada realizada no local de trabalho do professor, tendo em vista as necessidades e angústias frente à utilização dos recursos tecnológicos. Destacaram, ainda, a existência de distanciamento entre os cursos ofertados pelos Núcleos Regionais de Ensino e a prática pedagógica. Revelaram haver dificuldades e lacunas a serem superadas para que, realmente, ocorra a inclusão dos recursos tecnológicos na prática pedagógica e no cotidiano da escola. Essas lacunas incluem a manutenção dos laboratórios de informática do espaço escolar, a formação para uso das ferramentas tecnológicas, articulação entre<br />as tecnologias e os conteúdos curriculares. Com base nessa realidade, torna-se essencial repensar o processo de formação dos professores considerando o “chão da escola”, isto é, o lócus de trabalho dos professores.</p>

<p>Este trabalho é parte de uma pesquisa maior intitulada “História, Memória e Magistério: Formação de Professores Primários nas Escolas de Professores de Londrina – PR (1945-1970)”, que está sendo desenvolvida no âmbito do “Mestrado em Metodologias para o Ensino de Linguagens e suas Tecnologias” da Unopar, com apoio do CNPq. Este fragmento tem como objetivo principal analisar os encaminhamentos metodológicos recomendados em relação ao problema da indisciplina dos alunos, constantes em algumas cartas encontradas no acervo documental do Colégio Mãe de Deus. Três dessas cartas foram enviadas pela Irmã Maria Virgo aos seus pais na Alemanha, escritas respectivamente em 1939, 1940 e 1941 e que nunca chegaram ao seu destino, tendo sido retidas pelos censores nazistas. Outra carta foi enviada às Irmãs do Colégio pelo Padre José Kentenich no ano de 1936, respondendo a uma consulta sobre a possibilidade de uso de castigos físicos em casos de indisciplina.</p>

Published: May 2016

<p>O objetivo deste texto é analisar as atribuições formativas do coordenador pedagógico (CP), segundo a legislação, na relação com a percepção de profissionais que atuam em quatro escolas públicas – duas estaduais e duas municipais – do estado de São Paulo. Utilizam-se, como referencial teórico, os conceitos de Placco, Almeida e Souza (2011) e Roldão (2015), no que concerne à sustentação dos conceitos de formação e coordenação pedagógica. Os procedimentos adotados para a sistematização das ideias aqui expostas foram análise documental das leis e recortes de dados de pesquisa, contemplando questionários e entrevistas, realizada em 2010/2011 pelas autoras do texto. A análise do prescrito e do executado no cotidiano das escolas revelou que os coordenadores colocam como prioridade a dimensão formativa, mas, ao relacionarem as atividades que realizam no seu cotidiano, tal prioridade não acontece.</p><p> </p><p> </p>
Eu sei o que tenho que fazer: a conquista da autorregulação
Authors: Davis Claudia Leme Ferreira , Nunes Marina Muniz Rossa 
Published: May 2016

<p>A aprendizagem autorregulada vem sendo bastante estudada no campo da Psicologia da Educação, uma vez que permite aos alunos planejar, dirigir, monitorar e avaliar suas aprendizagens. No entanto, em muitas escolas, essas possibilidades não são conquistadas pelos estudantes, com graves prejuízos para a solução de problemas e, portanto, para o próprio pensar. De uma perspectiva vygotskiana, o presente artigo analisa um caso real – descrito pelos autores de acordo com sua ótica (mas referendado por alguns alunos) – e busca mostrar que é possível ensinar os alunos a se autorregularem. O estudo salienta, entretanto, que só se alcançará o sucesso dessa aprendizagem mediante a construção de relações de confiança na sala de aula e do entendimento do erro como parte inerente do aprender.</p><p> </p>

Published: May 2016

<p>Neste trabalho são propostos modelos para acompanhar a evolução do desempenho educacional médio em Matemática de um grupo de indivíduos avaliados ao longo do tempo no contexto da Teoria da Resposta ao Item, possibilitando a estimação de habilidades médias em períodos não avaliados. Foram avaliadas as curvas de crescimento linear, quadrática, logística e Gompertz. A característica longitudinal induz uma dependência entre as habilidades nos vários tempos de avaliação, sendo propostas algumas estruturas de covariância para modelar essa dependência. Os parâmetros dos itens foram considerados conhecidos de uma calibração prévia. Realizou-se uma aplicação em dados provenientes do Programa de Desenvolvimento da Educação (PDE-Escola/MEC). Verificou-se que a curva de crescimento logística, associada à estrutura de correlação AR(1), ajustou-se melhor aos dados, com uma altíssima correlação entre as habilidades estimadas, e que o maior ganho em habilidade ocorre até o final do 6º ano escolar.</p><p> </p><p> </p>
Hierarchical analysis of taxonomic variation in intraspecific competition across fish species

Published: May 2016

AbstractThe nature and intensity of intraspecific competition can vary greatly among taxa, yet similarities in these interactions can lead to similar population dynamics among related organisms. Variation along the spectrum of intraspecific competition, with contest and scramble competition as endpoints, leads to vastly different responses to population density. Here we investigated the diversity of intraspecific competition among fish species, predicting that functional forms of density‐dependent reproduction would be conserved in related taxa. Using a hierarchical model that links stock–recruitment parameters among populations, species, and orders, we found that the strength of overcompensation, and therefore the type of intraspecific competition, is tightly clustered within taxonomic groupings, as species within an order share similar degrees of compensation. Specifically, species within the orders Salmoniformes and Pleuronectiformes exhibited density dependence indicative of scramble competition (overcompensation) while the orders Clupeiformes, Gadiformes, Perciformes, and Scorpaeniformes exhibited dynamics consistent with contest competition (compensation). Maximum potential recruitment also varied among orders, but with less clustering across species. We also tested whether stock–recruitment parameters correlated with maximum body length among species, but found no strong relationship. Our results suggest that much of the variation in the form of density‐dependent reproduction among fish species may be predicted taxonomically due to evolved life history traits and reproductive behaviors.
Spatially explicit assessment of estuarine fish after Deepwater Horizon oil spill: trade‐off in complexity and parsimony

Published: May 2016

AbstractEvaluating long‐term contaminant effects on wildlife populations depends on spatial information about habitat quality, heterogeneity in contaminant exposure, and sensitivities and distributions of species integrated into a systems modeling approach. Rarely is this information readily available, making it difficult to determine the applicability of realistic models to quantify population‐level risks. To evaluate the trade‐offs between data demands and increased specificity of spatially explicit models for population‐level risk assessments, we developed a model for a standard toxicity test species, the sheepshead minnow (Cyprinodon variegatus), exposed to oil contamination following the Deepwater Horizon oil spill and compared the output with various levels of model complexity to a standard risk quotient approach. The model uses habitat and fish occupancy data collected over five sampling periods throughout 2008–2010 in Pensacola and Choctawhatchee Bays, Florida, USA, to predict species distribution, field‐collected and publically available data on oil distribution and concentration, and chronic toxicity data from laboratory assays applied to a matrix population model. The habitat suitability model established distribution of fish within Barataria Bay, Louisiana, USA, and the population model projected the dynamics of the species in the study area over a 5‐yr period (October 2009–September 2014). Vital rates were modified according to estimated contaminant concentrations to simulate oil exposure effects. To evaluate the differences in levels of model complexity, simulations varied from temporally and spatially explicit, including seasonal variation and location‐specific oiling, to simple interpretations of a risk quotient derived for the study area. The results of this study indicate that species distribution, as well as spatially and temporally variable contaminant concentrations, can provide a more ecologically relevant evaluation of species recovery from catastrophic environmental impacts but might not be cost‐effective or efficient for rapid assessment needs.
Variation in the age of first reproduction: different strategies or individual quality?

Published: May 2016

AbstractAlthough age at first reproduction is a key demographic parameter that is probably under high selective pressure, it is highly variable and the cause of this variability is not well understood. Two non‐exclusive hypotheses may explain such variability. It could be the expression of different individual strategies, i.e., different allocation strategies in fitness components, or the consequences of individual difference in intrinsic quality, i.e., some individuals always doing better than others in all fitness components. We tested these hypotheses in the Wandering Albatross investigating relationships between the age at first reproduction and subsequent adult demographic traits. Using finite mixture capture recapture modeling, we demonstrate that the age at first reproduction is negatively related to both reproductive performances and adult survival, suggesting that individual quality was an important factor explaining variation in the age at first reproduction. Our results suggest that age at first breeding is a good predictor of quality in this long‐lived seabird species.
Using plant‐soil feedbacks to predict plant biomass in diverse communities

Published: May 2016

AbstractIt has become clear that plants can create soils that affect subsequent plant growth. However, because plant‐soil feedbacks (PSFs) are typically measured in monoculture experiments, it remains unclear to what extent PSFs affect plant growth in communities. Here we used data from a factorial PSF experiment to predict the biomass of 12 species grown in 162 plant community combinations. Five different plant growth models were parameterized with either monoculture biomass data (Null) or with PSF data (PSF) and model predictions were compared to plant growth observed in communities. For each of the five models, PSF model predictions were closer to observed species biomass in communities than Null model predictions. PSFs, which were associated with a 28% difference in plant biomass across soil types, explained 10% more variance than Null models. Results provided strong support for a small role for PSFs in predicting plant growth in communities and suggest several reasons that PSFs, as traditionally measured in monoculture experiments, may overestimate PSF effects in communities. First, monoculture data used in Null models inherently includes “self ” PSF effects. Second, PSFs must be large relative to differences in intrinsic growth rates among species to change competitive outcomes. Third, PSFs must vary among species to change species relative abundances.

Near‐Infrared Spectroscopy as a Tool for Generating Sorption Input Parameters for Pesticide Fate Modeling
Authors: Singh Baljeet , Farenhorst Annemieke , McQueen Ross , Malley Diane F. 
Published: May 2016

Core Ideas
NIRS can be integrated with pesticide fate models using a test set method.
NIRS calibrations are most successful for pesticides with smaller Kd values.
Regional scale NIRS calibrations are most successful if developed on data sets of similar Kd value range.
Sorption parameters (such as Kd values) are among the most sensitive input parameters in pesticide fate models. This study demonstrates that near‐infrared spectroscopy (NIRS), in combination with batch equilibrium techniques, can be used to estimate Kd values, thereby increasing throughput of the many samples required to characterize spatial variability of pesticide sorption within fields. The Pesticide Root Zone Model version 3.12.2 (PRZM‐3) was used to compare scenarios that used NIRS spectral data, pedotransfer functions, and batch equilibrium methods as inputs for the calculation of 2,4‐dichlorophenoxyacetic acid (2,4‐D) and atrazine leaching in 591 soil horizons. Based on the 3564 simulation runs conducted, we concluded that the added benefit of NIRS is most useful when the pesticides under study have small sorption potentials and short half‐lives in soil. The 2,4‐D and atrazine sorption by soil was highly correlated to soil organic C (SOC) content in the fields under study. The feasibility of using NIRS to predict pesticide Kd values largely relies on the sorption of the pesticide being significantly correlated to SOC. In addition, successful regional approaches to predicting Kd values from NIRS spectral data can also be developed when the calibration model is derived by combining a set of fields where each has a similar statistical population characteristic in Kd values.
Characterization of Washoff Behavior of In‐Sewer Deposits in Combined Sewer Systems
Authors: Kim WeonJae , Furumai Hiroaki 
Published: May 2016

ABSTRACT: In‐sewer deposits in combined sewer systems (CSSs) are closely related with the behavior of first foul flush and combined sewer overflows. The artificial flushing experiment separating the washoff of in‐sewer deposits from the inflow of surface pollutants was carried out to simulate first foul flush in a CSS. The washoff behaviors of each pollutant including chemical pollutants, bacterial indicators, and enteric viruses were intensively investigated. By using several morphological analyses, some of which were suggested through this study, the characteristics of first foul flush were examined. As a result, the washoff behaviors of each pollutant were characterized according to their (i) event load ratios (ELRs), (ii) time‐series concentration and load curves, (iii) concentration vs. flow rate curves, and (iv) dimensionless runoff concentrations (DRCs). The first foul flush patterns of each parameter were categorized into 3 typical groups: the strong‐, partial‐, and no first foul flush group. The order of these groups signifies their different physicochemical properties of in‐sewer deposits in CSSs, their strength of first foul flush phenomena, and the washoff priority as well.

ABSTRACT
Supermassive black holes observed at high redshift

could grow from direct collapse black holes (DCBHs) with masses

, which result from the collapse of supermassive stars (SMSs). If a relativistic jet is launched from a DCBH, then it can break out of the collapsing SMS and produce a gamma-ray burst (GRB). Although most GRB jets are off-axis from our line of sight, we show that the energy injected from the jet into a cocoon is huge

events per year, providing direct evidence of the DCBH scenario.

Published: May 2016

ABSTRACT
NGC 1042 is a late-type bulgeless disk galaxy that hosts low-luminosity active galactic nuclei (AGNs) coincident with a massive nuclear star cluster. In this paper, we present the integral field spectroscopy studies of this galaxy, based on the data obtained with the Mitchell spectrograph on the 2.7 m Harlan J. Smith telescope. In the central 100–300 pc region of NGC 1042, we find a circumnuclear ring structure of gas with enhanced ionization, which we suggest is mainly induced by shocks. Combining this with the harmonic decomposition analysis of the velocity field of the ionized gas, we propose that the shocked gas is the result of gas inflow driven by the inner spiral arms. The inflow velocity is

, and the estimated mass-inflow rate is

. The mass-inflow rate is about one hundred times the black hole’s mass-accretion rate (

) and slightly larger than the star-formation rate in the nuclear star cluster (

), implying that the inflow material is enough to feed both the AGN activity and star formation in the nuclear star cluster. Our study highlights that secular evolution can be important in late-type unbarred galaxies like NGC 1042.

ABSTRACT
Current generation low-frequency interferometers constructed with the objective of detecting the high-redshift 21 cm background aim to generate power spectra of the brightness temperature contrast of neutral hydrogen in primordial intergalactic medium. Two-dimensional (2D) power spectra (power in Fourier modes parallel and perpendicular to the line of sight) that formed from interferometric visibilities have been shown to delineate a boundary between spectrally smooth foregrounds (known as the wedge) and spectrally structured 21 cm background emission (the EoR window). However, polarized foregrounds are known to possess spectral structure due to Faraday rotation, which can leak into the EoR window. In this work we create and analyze 2D power spectra from the PAPER-32 imaging array in Stokes I, Q, U, and V. These allow us to observe and diagnose systematic effects in our calibration at high signal-to-noise within the Fourier space most relevant to EoR experiments. We observe well-defined windows in the Stokes visibilities, with Stokes Q, U, and V power spectra sharing a similar wedge shape to that seen in Stokes I. With modest polarization calibration, we see no evidence that polarization calibration errors move power outside the wedge in any Stokes visibility to the noise levels attained. Deeper integrations will be required to confirm that this behavior persists to the depth required for EoR detection.
A SEARCH FOR SUB-SECOND RADIO VARIABILITY PREDICTED TO ARISE TOWARD 3C 84 FROM INTERGALACTIC DISPERSION

Published: May 2016

ABSTRACT
We empirically evaluate the scheme proposed by Lieu & Duan in which the light curve of a time-steady radio source is predicted to exhibit increased variability on a characteristic timescale set by the sightline’s electron column density. Application to extragalactic sources is of significant appeal, as it would enable a unique and reliable probe of cosmic baryons. We examine temporal power spectra for 3C 84, observed at 1.7 GHz with the Karl G. Jansky Very Large Array and the Robert C. Byrd Green Bank Telescope. These data constrain the ratio between standard deviation and mean intensity for 3C 84 to less than 0.05% at temporal frequencies ranging between 0.1 and 200 Hz. This limit is 3 orders of magnitude below the variability predicted by Lieu & Duan and is in accord with theoretical arguments presented by Hirata & McQuinn rebutting electron density dependence. We identify other spectral features in the data consistent with the slow solar wind, a coronal mass ejection, and the ionosphere.
