Authors: Beato-Canato Ana Paula Marques , Cristovão Vera Lúcia Lopes 
Published: May 2017

Em uma perspectiva interacionista sociodiscursiva, advogamos que, para alcançar seus objetivos, o trabalho com línguas na rede regular pública de ensino pode ser planejado em sequências didáticas organizadas em torno degêneros textuais. Tais unidades visam ao desenvolvimento de capacidades de linguagem, entendidas como “aptidões requeridas para a realização de um texto numa situação de interação determinada” (DOLZ; PASQUIER; BRONCKART, 1993, p.30). A partir desses pressupostos, sequências didáticas foram aplicadas a alunos de uma escola municipal de Joinville, ao longo de um ano escolar, com o objetivo de possibilitar a participação efetiva em um projeto de troca de correspondências. Dentre os gêneros abordados, selecionamos receitas culinárias para o escopo deste artigo, que visa, assim, descrever o material elaborado e analisar as produções de um aluno de modo a ilustrar oportunidades (ou não) de desenvolvimento de capacidades de linguagem possibilitadas por um trabalho dessa natureza. Palavras-chave: Interacionismo Sociodiscursivo; gênero textual receita culinária; sequência didática; ensino-aprendizagem de língua inglesa; desenvolvimentode capacidades de linguagem.The work with a didactic sequence of recipes in English as an additional language in a public schoolAbstract In a sociodiscursive interactionist perspective, we advocate that, to achieve its goals, the work with languages in public regular schools can be planned in didactic sequences towards genres. Such units aim at the development of language capacities (DOLZ; PASQUIER; BRONCKART, 1993). Based on these principles, didactic sequences were employed with students of a public school in Joinville, during a school year, with the objective of contributing to their effective participation in a pen pal Project. Among the genres handled, cooking recipeswere taken as scope of this paper, which aims at describing the material planned and analyze the productions of one student in order to illustrate the opportunities of language capacities development enabled by a work of thisnature.Keywords: Sociodiscursive Interacionism; genre cooking recipe; didactic sequences; English language teaching/learning; language capacities development.

Authors: Ferreira Amauri Carlos , Santos Lorene dos 
Published: May 2017

ResumoA morada da ética é o outro. Mas quem é este outro? De que outro falamos no ambiente escolar? É possível educar para a diversidade? A partir destas indagações procuramos discutir a questão do outro que indagou a ética e a educação no início dos anos de 1990. Este artigo está circunscrito na fronteira da relação professor/estudante, tendo como elemento interveniente o preconceito com os recém-chegados à escola. Para melhor compreender a formação do éthos diverso em abordagens contra o preconceito, tecemos reflexões no campo da diversidade étnico racial. Foram mapeadas algumas conquistas no plano da legislação e das políticas públicas em educação.Apresentamos dados de pesquisas que evidenciam formas de manifestação do preconceito racial e alguns dos dilemas e desafios de professores comprometidos com o trato da diversidade na construção de novas relações no espaço escolar.Palavras Chaves: Educação; Ética; Diversidade; Preconceito racial; Building the éthos of diversity and education of ethnic racial relationshipsAbstract The living place of ethics is the Other. But, who is the Other? Who is this Other we talk about in the academic environment? Is it possible to educate for diversity? These questions are the starting point of a discussion about the Other that questioned ethics and education in the 1990's. This paper is about the teacher/student relationship, focusing on discrimination against the newcomers in school. A better understanding of the process of building the éthos of diversity comes from reflections in the field of racial ethnic diversity. We maped the achievements against discrimination in the legislative domain and public policy education. Our research data indicates various manifestations of racial prejudice and some of the dilemmas and challenges teachers committed to diversity when dealing with new relationships in school.Keywords: Education; Ethics; Diversity; Racial prejudice.

Resumo A criatividade tem sido foco de pesquisas em diversas áreas do saber. Entretanto, é no contexto educacional, especificamente no Ensino Superior, que estudos evidenciam o potencial da criatividade na produção do conhecimento crítico e na autonomia dos sujeitos. Este artigo apresenta resultados de uma pesquisa bibliográfica que objetivou realizar o levantamento do Estado da Arte sobre a Criatividade no Ensino Superior. Foram encontrados 244 artigos na SciELO (Scientific Electronic Library Online). Apenas nove referem-se ao nível de Ensino Superior. A maioria desses estudos aborda a opinião de professores e alunos sobre as práticas docentes referentes às barreiras ou formas de desenvolvimento da criatividade. As metodologias da coleta de dados, em geral, foram constituídas de instrumentos criados pelos próprios autores. Esta pesquisa possibilitou-nos delinear a abordagem dos estudos relacionados à criatividade no Ensino Superior, na base SciELO, identificando-se a escassez de pesquisas. Colocando a criatividade como tema importante a ser desenvolvido.Palavras-chave: Criatividade; Estado da Arte; Ensino Superior. A State-of-the-art Review of Research on Creativity in Higher Education AbstractCreativity has been the focus of researches in several fields. However, it is in Education, mainly in Higher Education, that studies have pointed out the capacity creativity has to yield critical knowledge and autonomy.This paper shows the results of a bibliographical study which aimed at carrying out a state-of-the-art review of creativity in Higher Education. Only 9 out of 244 papers found in SciELO (Scientific Electronic Library Online) referred to Higher Education. It is worth highlighting that most studies which aimed at investigating Higher Education have addressed professors’ and students’ opinions about teaching practices related to barriers and ways to develop creativity. The methodology applied to collect data on the papers comprised tools we have developed. This study enabled us to outline the approach given to researches of creativity in Higher Education in the SciELO database and identify the shortage of studies in the area, an evidence of the fact that creativity is a fertile and important theme to be developed in the future.

SEM and TEM Methods for the Quantification of Gamma-Prime Precipitates in Nickel Alloys
Authors: Speicher M. , Scheck R. , Willer D. , Maile K. 
Published: May 2017

Abstract
This work presents the quantitative evaluation of the gamma-prime phase for two nickel-based alloys which contain different proportions of this phase. Alloy 617 mod. was chosen here as an example for nickel alloys with a small volume fraction of the gamma-prime phase, while Alloy 263 was chosen as a material with a higher proportion. The examinations are performed in the scanning electron microscope (SEM) with high resolution as well as with a transmission electron microscope (TEM). The methods of quantitative recording are discussed. The results of the SEM and TEM analyses are compared and discussed. Several etching techniques were applied for the sample preparation.
A Physical Model-based Correction for Charge Traps in the Hubble Space Telescope’s Wide Field Camera 3 Near-IR Detector and Its Applications to Transiting Exoplanets and Brown Dwarfs
Authors: Zhou Yifan , Apai Dániel , Lew Ben W. P. , Schneider Glenn 
Published: May 2017

Abstract
The Hubble Space Telescope Wide Field Camera 3 (WFC3) near-IR channel is extensively used in time-resolved observations, especially for transiting exoplanet spectroscopy as well as brown dwarf and directly imaged exoplanet rotational phase mapping. The ramp effect is the dominant source of systematics in the WFC3 for time-resolved observations, which limits its photometric precision. Current mitigation strategies are based on empirical fits and require additional orbits to help the telescope reach a thermal equilibrium. We show that the ramp-effect profiles can be explained and corrected with high fidelity using charge trapping theories. We also present a model for this process that can be used to predict and to correct charge trap systematics. Our model is based on a very small number of parameters that are intrinsic to the detector. We find that these parameters are very stable between the different data sets, and we provide best-fit values. Our model is tested with more than 120 orbits (∼40 visits) of WFC3 observations and is proved to be able to provide near photon noise limited corrections for observations made with both staring and scanning modes of transiting exoplanets as well as for starting-mode observations of brown dwarfs. After our model correction, the light curve of the first orbit in each visit has the same photometric precision as subsequent orbits, so data from the first orbit no longer need to be discarded. Near-IR arrays with the same physical characteristics (e.g., JWST/NIRCam) may also benefit from the extension of this model if similar systematic profiles are observed.
A Close-up View of the Young Circumbinary Disk HD 142527
Authors: Boehler Y. , Weaver E. , Isella A. , Ricci L. , Grady C. , Carpenter J. , Perez L. 
Published: May 2017

Abstract
We present ALMA observations of the 0.88 millimeter dust continuum and the 13CO and C18O J = 3-2 line emission of the circumbinary disk HD 142527 at a spatial resolution of ∼0.″25. This system is characterized by a large central cavity of roughly 120 au in radius, and asymmetric dust and gas emission. By comparing the observations with theoretical models, we find that the azimuthal variations in gas and dust density reach a contrast of 54 for dust grains and 3.75 for CO molecules, with an extreme gas-to-dust ratio of 1.7 on the dust crescent. We point out that caution is required in interpreting continuum-subtracted maps of the line emission, as this process might result in removing a large fraction of the line emission. Radially, we find that both the gas and dust surface densities can be described by Gaussians, centered at the same disk radius, and with gas profiles wider than those for dust. These results strongly support a scenario in which millimeter dust grains are radially and azimuthally trapped toward the center of a gas pressure bump. Finally, our observations reveal a compact source of continuum and CO emission inside the dust-depleted cavity ∼50 au from the primary star. The kinematics of the CO emission from this region is different from that expected from material in Keplerian rotation around the binary system, and might instead trace a compact disk around a third companion. Higher angular resolution observations are required to investigate the nature of this source.
Supernova Driving. IV. The Star-formation Rate of Molecular Clouds
Authors: Padoan Paolo , Haugbølle Troels , Nordlund Åke , Frimann Søren 
Published: May 2017

Abstract
We compute the star-formation rate (SFR) in molecular clouds (MCs) that originate ab initio in a new, higher-resolution simulation of supernova-driven turbulence. Because of the large number of well-resolved clouds with self-consistent boundary and initial conditions, we obtain a large range of cloud physical parameters with realistic statistical distributions, which is an unprecedented sample of star-forming regions to test SFR models and to interpret observational surveys. We confirm the dependence of the SFR per free-fall time, SFRff, on the virial parameter, α
vir, found in previous simulations, and compare a revised version of our turbulent fragmentation model with the numerical results. The dependences on Mach number,

, gas to magnetic pressure ratio, β, and compressive to solenoidal power ratio, χ at fixed α
vir are not well constrained, because of random scatter due to time and cloud-to-cloud variations in SFRff. We find that SFRff in MCs can take any value in the range of 0 ≤ SFRff ≲ 0.2, and its probability distribution peaks at a value of SFRff ≈ 0.025, consistent with observations. The values of SFRff and the scatter in the SFRff–α
vir relation are consistent with recent measurements in nearby MCs and in clouds near the Galactic center. Although not explicitly modeled by the theory, the scatter is consistent with the physical assumptions of our revised model and may also result in part from a lack of statistical equilibrium of the turbulence, due to the transient nature of MCs.
Evolution of Compact and Fossil Groups of Galaxies from Semi-analytical Models of Galaxy Formation

Published: May 2017

Abstract
We compare the mean mass assembly histories of compact and fossil galaxy groups in the Millennium Dark Matter Simulation and an associated semi-analytic galaxy formation model. Tracing the halo mass of compact groups (CGs) from z = 0 to z = 1 shows that, on average, 55% of the halo mass in CGs is assembled since

, compared to 40% of the halo mass in fossil groups (FGs) on the same time interval, indicating that compared to FGs, CGs are relatively younger galaxy systems. At z = 0, for a given halo mass, FGs tend to have a larger concentration than CGs. Investigating the evolution of CG’s parameters reveals that they become more compact with time. CGs at z = 0.5 see their magnitude gaps increase exponentially, but it takes ∼10 Gyr for them to reach a magnitude gap of 2 mag. The slow growth of the magnitude gap leads to only a minority (∼41%) of CGs selected at z = 0.5 turning into a FG by z = 0. Also, while three-quarters of FGs go through a compact phase, most fail to meet the CG isolation criterion, leaving only ∼30% of FGs fully satisfying the CG selection criteria. Therefore, there is no strong link of CGs turning into FGs or FGs originating from CGs. The relation between CGs and FGs is thus more complex, and in most cases, FGs and CGs follow different evolutionary tracks.
Far-ultraviolet to Near-infrared Spectroscopy of a Nearby Hydrogen-poor Superluminous Supernova Gaia16apd

Abstract
We report the first maximum-light far-ultraviolet (FUV) to near-infrared (NIR) spectra (1000 Å − 1.62 μm, rest) of a hydrogen-poor superluminous supernova, Gaia16apd. At z = 0.1018, it is the second closest and the UV brightest SLSN-I, with 17.4 mag in Swift UVW2 band at −11 days pre-maximum. The coordinated observations with HST, Palomar, and Keck were taken at −2 to +25 days. Assuming an exponential (or t
2) form, we derived the rise time of 33 days and the peak bolometric luminosity of 3 × 1044 erg s−1. At the maximum, the photospheric temperature and velocity are 17,000 K and 14,000 km s−1, respectively. The inferred radiative and kinetic energy are roughly 1 × 1051 and 2 × 1052 erg. Gaia16apd is extremely UV luminous, and emits 50% of its total luminosity at 1000–2500 Å. Compared to the UV spectra (normalized at 3100 Å) of well studied SN1992A (Ia), SN2011fe (Ia), SN1999em (IIP), and SN1993J (IIb), it has orders of magnitude more FUV emission. This excess is interpreted primarily as a result of weaker metal-line blanketing due to a much lower abundance of iron group elements in the outer ejecta. Because these elements originate either from the natal metallicity of the star, or have been newly produced, our observation provides direct evidence that little of these freshly synthesized material, including 56Ni, were mixed into the outer ejecta, and the progenitor metallicity is likely sub-solar. This disfavors Pair-instability Supernova models with helium core masses

, where substantial 56Ni material is produced. A higher photospheric temperature definitely contributes to the FUV excess from Gaia16apd. Compared with Gaia16apd, we find PS1-11bam is also UV luminous.
Angular Momentum Transfer and Fractional Moment of Inertia in Pulsar Glitches
Authors: Eya I. O. , Urama J. O. , Chukwude A. E. 
Published: May 2017

Abstract
We use the Jodrell Bank Observatory glitch database containing 472 glitches from 165 pulsars to investigate the angular momentum transfer during rotational glitches in pulsars. Our emphasis is on pulsars with at least five glitches, of which there are 26 that exhibit 261 glitches in total. This paper identifies four pulsars in which the angular momentum transfer, after many glitches, is almost linear with time. The Lilliefore test on the cumulative distribution of glitch spin-up sizes in these glitching pulsars shows that glitch sizes in 12 pulsars are normally distributed, suggesting that their glitches originate from the same momentum reservoir. In addition, the distribution of the fractional moment of inertia (i.e., the ratio of the moment of inertia of neutron star components that are involved in the glitch process) have a single mode, unlike the distribution of fractional glitch size (Δν/ν), which is usually bimodal. The mean fractional moment of inertia in the glitching pulsars we sampled has a very weak correlation with the pulsar spin properties, thereby supporting a neutron star interior mechanism for the glitch phenomenon.
Plasma Heating in Solar Microflares: Statistics and Analysis
Authors: Kirichenko A. S. , Bogachev S. A. 
Published: May 2017

Abstract
In this paper we present the results of an analysis of 481 weak solar flares, from A0.01 class flares to the B GOES class, that were observed during the period of extremely low solar activity from 2009 April to July. For all flares we measured the temperature of the plasma in the isothermal and two-temperature approximations and tried to fit its relationship with the X-ray class using exponential and power-law functions. We found that the whole temperature distribution in the range from A0.01 to X-class cannot be fit by one exponential function. The fitting for weak flares below A1.0 is significantly steeper than that for medium and large flares. The power-law approximation seems to be more reliable: the corresponding functions were found to be in good agreement with experimental data both for microflares and for normal flares. Our study predicts that evidence of plasma heating can be found in flares starting from the A0.0002 X-ray class. Weaker events presumably cannot heat the surrounding plasma. We also estimated emission measures for all flares studied and the thermal energy for 113 events.
A Complex Solar Coronal Jet with Two Phases
Authors: Chen Jie , Su Jiangtao , Deng Yuanyong , Priest E. R. 
Published: May 2017

Abstract
Jets often occur repeatedly from almost the same location. In this paper, a complex solar jet was observed with two phases to the west of NOAA AR 11513 on 2012 July 2. If it had been observed at only moderate resolution, the two phases and their points of origin would have been regarded as identical. However, at high resolution we find that the two phases merge into one another and the accompanying footpoint brightenings occur at different locations. The phases originate from different magnetic patches rather than being one phase originating from the same patch. Photospheric line of sight (LOS) magnetograms show that the bases of the two phases lie in two different patches of magnetic flux that decrease in size during the occurrence of the two phases. Based on these observations, we suggest that the driving mechanism of the two successive phases is magnetic cancellation of two separate magnetic fragments with an opposite-polarity fragment between them.
