A contemporaneidade da crise da educação no pensamento de Hannah Arendt
Authors: Belinaso Guimarães Rodrigo 
Published: August 2019

Resumo: A escola pública é o local principal dos questionamentos deste artigo. Nele, a sala de aula é vista como um espaço de aprendizagem significativo e onde ainda podem ocorrer encontros fundamentais para a constituição do mundo na perspectiva de Hannah Arendt (2002). Atualmente, os sintomas da crise na educação fazem com que a sala de aula se converta num espaço de angústias e frustrações, assim, jovens e professores podem ter uma relação muitas vezes marcada pelo desinteresse, pelo isolamento, pela opressão, pela violência, que impede qualquer abertura para o vir a ser. Assim, pergunto-me sobre a forma como posso dotar de sentido minha prática de professor e pesquisador, diferenciando-me dos papéis que não quero assumir. Em outras palavras, questiono neste artigo sobre a possibilidade de abdicar de pronunciar aos jovens como deve ser o vir a ser do mundo em que habitam. Para isso, parto de um sentimento de crise, vivenciado nas dificuldades de aprendizagem e nos encontros interditos em sala de aula, que me convidam a um repensar constante sobre minha prática educativa. Dessa forma, procuro sintetizar alguns conceitos fundamentais de Hannah Arendt sobre a crise da educação, percorrendo seu pensamento para, por fim, relacioná-los com a contemporaneidade das minhas vivências. Palavras-chave: Educação. Estudos Culturais. Ensino Médio. Crise na Educação. Hannah Arendt. THE CONTEMPORARY EDUCATION CRISIS IN THOUGHT OF HANNAH ARENDT Abstract: The public school is the main place of the questions in this article. In it, the classroom is seen as a significant learning space and where can still occur important meetings for the foundation of the world in the Hannah Arendt’s perspective (2002). Nowadays, the symptoms of the crisis in education makes the classroom becomes an area of anguish and frustration, thus, youth and teachers can have a relationship often marked by indifference, isolation, oppression, violence, obstructing any opening to become to be. So, I wonder about how I can give direction to my practice teacher and researcher, differentiating me from the papers that do not want to take. In other words, I question in this article about the possibility of giving up to pronounce for the young people how must to be the world they to live. For this, I start of a sense of crisis; it has lived in the difficulties of learning and banned gatherings in the classroom, which invites me to a constant rethinking about my educational practice. In this way, I try to summarize some Hannah Arendt’s concepts about the education crisis, covering their thinking to finally compare them to the contemporary nature of my experiences.

Inovação pedagógica e tecnológica na formação inicial de professores
Authors: Guidotti Charles Dos Santos , Mackedanz Luiz Fernando 
Published: August 2019

Resumo: Este artigo analisa a forma e os desafios de inserção das Tecnologias de Informação e Comunicação (TIC) na formação inicial de professores de Física. O objetivo geral é investigar os cursos de formação de professores, em nível de graduação, quanto aos conhecimentos referentes às TIC em sua base curricular, assim como compreender quais são os desafios desses cursos para proporcionar tal formação com qualidade. Partimos da hipótese de que os cursos de formação de professores de Física estão proporcionando poucos momentos que possibilitam problematizar as TIC durante a formação do educador, o qual não estaria percebendo a importância desses recursos e dos conhecimentos inerentes a eles, bem como a contribuição que possibilitam à prática educativa. Desse modo, essa investigação está focada na formação do futuro professor de Física da Educação Básica para o uso das TIC. Para isso, focalizamos a investigação nos cursos de licenciatura em Física de cinco universidades federais do RS, analisando os projetos pedagógicos desses cursos e realizando entrevistas com professores formadores dessas instituições. Esta pesquisa confirmou a necessidade de pensarmos em uma estrutura formativa menos fragmentada, em que as TIC – e não só elas – sejam discutidas em diferentes contextos e ambientes, de forma a permear todo o curso de formação.

PEDAGOGICAL AND TECHNOLOGICAL INNOVATION IN TEACHERS’ INITIAL FORMATION Abstract: This article looks at the way and the challenges of integration of Information and Communication Technologies (ICT) in Physics teachers initial training. The overall objective is to investigate teacher training courses at the undergraduate level, as the knowledge related to ICT in their curriculum base, as well as understand what are the challenges for these courses provide such training quality. Our hypothesis is that the Physics teacher initial training courses are providing few moments that make it possible to question the ICT during the formation of the educator, which would not realize the importance of these resources and inherent knowledge as well as the contribution that enable the educational practice. Thus, this research is focused on the training of future Physics teachers in Basic Education in order to use ICT. Then, we focus on research in undergraduate Physics courses in five Federal Universities of the state of Rio Grande do Sul, in order to analyze the educational projects of these courses and to conduct interviews with teachers trainers of these institutions. This research confirmed the need to think of a less fragmented structure training in ICT - and not only them – will be discussed in different contexts and environments in order to permeate the whole training course.

Como questionamos a ditadura nas aulas de Geografia
Authors: Batista Bruno Nunes 
Published: August 2019

Resumo: Este texto compartilha experiências pedagógicas desenvolvidas em turmas de Ensino Médio, nas aulas de Geografia, a partir da temática relacionada à ditadura midiática-civil-militar no Brasil. Fazendo alusão aos cinquenta anos do golpe militar, em 1964, elaborou-se um conjunto de sequências didáticas associando a globalização ao período dos “anos de chumbo”. Nossa construção didática esteve amparada na sociologia crítica da mídia de Edgar Morin, Juremir Machado da Silva e Pedrinho Guareschi. Desse modo, as atividades privilegiaram a interpretação da influência da grande mídia no apoio ao golpe e na estabilidade política da ditadura. Foram empregados recursos didáticos diversificados, como a análise de reportagens históricas, a compreensão de programas audiovisuais da época e o trabalho com imagens. Durante as aulas, destacamos a inseparabilidade entre os conceitos de espaço e tempo no ensino de Geografia. Com efeito, ao compreenderem a contemporaneidade sociopolítica brasileira como corolário de uma historicidade, os sujeitos envolvidos nos processos de ensino e aprendizagem podem operar qualitativamente na sociedade da informação, instituindo um olhar crítico sobre os meios de comunicação; logo, formando uma teia própria de conhecimento. Palavras-chave: Ensino de Geografia. Ditadura na escola. Crítica da mídia. Aprendizagem. HOW CAN WE QUESTION DICTATORSHIP IN GEOGRAPHY CLASSES Abstract: This paper aims at sharing pedagogical practices developed in high school Geography classes. Their main subject was media-civil-military dictatorship in Brazil. The fiftieth anniversary of 1964 Brazilian military coup d’état motivated the production of a set of educational activities which associate globalization with the so called “anos de chumbo” (plumb years). Our theoretical framework relies on the works of media critical sociology of Edgar Morin, Juremir Machado da Silva and Pedrinho Guareschi. Thereby, the activities focused on interpretation of great media and communication's role on supporting the coup d’état and dictatorship maintenance. Diverse educational resources were employed, varying from historical materials analysis, image observation and audiovisual programs discussion from that political period. In class, we tried to stress the necessity of connecting geographical concepts of time and space. From that, we would argue that students who understand Brazilian social-political contemporary elements as a historical process are able to look critically at the information society media; therefore spinning their own knowledge web.

Dust Transport and Processing in Centrifugally Driven Protoplanetary Disk Winds
Authors: Giacalone Steven , Teitler Seth , Königl Arieh , Krijt Sebastiaan , Ciesla Fred J. 
Published: August 2019

Abstract
There is evidence that protoplanetary disks—including the protosolar one—contain crystalline dust grains on spatial scales where the dust temperature is lower than the threshold value for their formation through thermal annealing of amorphous interstellar silicates. We interpret these observations in terms of an extended, magnetocentrifugally driven disk wind that transports grains from the inner disk—where they are thermally processed by the stellar radiation after being uplifted from the disk surfaces—to the outer disk regions. For any disk radius r, there is a maximum grain size a
max(r) that can be uplifted from that location: grains of size a ≪ a
max are carried away by the wind, whereas those with a ≲ a
max reenter the disk at larger radii. A significant portion of the reentering grains converge to—and subsequently accumulate in—a narrow region just beyond r
max(a), the maximum radius from which grains of size a can be uplifted. We show that this model can account for the inferred crystallinity fractions in classical T Tauri and Herbig Ae disks and for their indicated near constancy after being established early in the disk evolution. It is also consistent with the reported radial gradients in the mean grain size, crystallinity, and crystal composition. In addition, this model yields the properties of the grains that remain embedded in the outflows from protoplanetary disks and naturally explains the inferred persistence of small grains in the surface layers of these disks.
Partially Ionized Solar Atmosphere: Two-fluid Waves and Their Cutoffs
Authors: Wójcik D. , Murawski K. , Musielak Z. E. 
Published: August 2019

Abstract
A novel model of the solar atmosphere that accounts for partially ionized plasma is developed and used to study the propagation of magnetoacoustic-gravity waves, which are generated by solar granulation. The model includes neutrals in otherwise ionized plasma and therefore the considered waves are two-fluid waves. Numerical simulations of these waves allow computing their cutoff period and its variations in the solar atmosphere. The results of these computations are compared to the observational data collected by Wiśniewska et al. and Kayshap et al., and a good agreement between the theory and observations is obtained. This first theoretical confirmation of the observational data profoundly shows the importance of effects caused by partially ionized plasma on the behavior of waves in the solar atmosphere, and on the origin of solar chromospheric oscillations. It is also suggested that theoretically predicted differences between the behavior of ions and neutrals can be verified by some currently operating solar missions.
Aerosol radiative effects with MACv2
Authors: Kinne Stefan 
Published: August 2019

Abstract. Monthly global maps for aerosol properties of the Max Planck Aerosol Climatology version 2 (MACv2) are
applied in an offline radiative transfer model to determine aerosol
radiative effects. This model setup cannot address rapid adjustments by
clouds, but current evidence suggests their contribution to be small when
compared to the instantaneous radiative forcing. Global maps are presented
to detail the regional and seasonal variability associated with (annual)
global averages. Radiative effects caused by the aerosol presence (direct
effects) and by aerosol modified clouds (indirect effects) are examined.
Direct effects are determined for total aerosol, anthropogenic aerosol and
extracted individual aerosol components. Indirect effects cover the impact
of reduced cloud drop sizes by anthropogenic aerosol. Present-day global annual radiative effects for anthropogenic aerosol yield
(1) a climate cooling of −1.0 W m−2 at the top of the atmosphere (TOA); (2) a
surface net-flux reduction of −2.1 W m−2; and, by difference; (3) an
atmospheric effect of +1.1 W m−2. This atmospheric solar heating is
almost entirely a direct effect. On a global basis, indirect effects (−0.65 W m−2) dominate direct effects
(−0.35 W m−2) for the present-day climate
response at the TOA, whereas the present-day surface radiative budget is
more strongly reduced by direct effects (−1.45 W m−2) than by indirect effects
(−0.65 W m−2). Natural aerosols are on average less absorbing and larger in size. However,
their stronger solar TOA cooling efficiency is offset by a non-negligible
infrared (IR) greenhouse warming efficiency. In the sum the global average
annual direct forcing efficiencies (per unit AOD) for natural and
anthropogenic aerosol are similar: −12 W m−2 per unit AOD for all-sky conditions and
−24 W m−2 per unit AOD for clear-sky conditions. The present-day direct TOA impact by all soot (BC) is
+0.55 W m−2, when globally and annually averaged. Between +0.25 and +0.45 W m−2 of that can be attributed to
anthropogenic sources, depending on assumptions for the preindustrial BC
reference state. Similarly, the preindustrial fine-mode reference
uncertainty has a strong influence not just on the direct effect but even more on the indirect effect. Present-day aerosol TOA forcing is estimated to stay
within the −0.7 to −1.6 W m−2 range (with the best estimate at −1.0 W m−2). Calculations with scaled temporal changes to anthropogenic AOD from global
modeling indicate that the global annual aerosol forcing has not changed
much over the last decades, despite strong shifts in regional maxima for
anthropogenic AOD. These regional shifts explain most solar insolation
(brightening or dimming) trends that have been observed by ground-based
radiation data.
Decreasing uncertainty in flood frequency analyses by including historic flood events in an efficient bootstrap approach
Authors: Bomers Anouk , Schielen Ralph M. J. , Hulscher Suzanne J. M. H. 
Published: August 2019

Abstract. Flood frequency curves are usually highly uncertain since they are based on short data sets of measured discharges or weather conditions. To decrease the confidence intervals, an efficient bootstrap method is developed in this study. The Rhine river delta is considered as a case study. We use a hydraulic model to normalize historic flood events for anthropogenic and natural changes in the river system. As a result, the data set of measured discharges could be extended by approximately 600 years. The study shows that historic flood events decrease the confidence interval of the flood frequency curve significantly, specifically in the range of large floods. This even applies if the maximum discharges of these historic flood events are highly uncertain themselves.
California earthquake insurance unpopularity: the issue is the price, not the risk perception
Authors: Pothon Adrien , Gueguen Philippe , Buisine Sylvain , Bard Pierre-Yves 
Published: August 2019

Abstract. Despite California being a highly seismic prone region, most homeowners are not covered against this risk. This study analyses the reasons for homeowners to purchase insurance to cover earthquake losses, with application in California. A dedicated database is built from 18 different data sources about earthquake insurance, gathering data since 1921. A new model is developed to assess the take-up rate based on the homeowners’ risk awareness and the average annual insurance premium amount. Results suggest that only two extreme situations would lead all owners to cover their home with insurance: (1) a widespread belief that a devastating earthquake is imminent, or alternatively (2) a massive decrease in the average annual premium amount by a factor exceeding 6 (from USD 980 to 160, 2015 US dollars). Considering the low likelihood of each situation, we conclude from this study that new insurance solutions are necessary to fill the protection gap.
Ferrymead Bridge

Published: August 2019

Identified in the Christchurch Lifelines Study as a bridge vulnerable to damage in a major earthquake, the Ferrymead Bridge on the key arterial route connecting the suburbs of Redcliffs and Sumner to the rest of Christchurch has subsequently been under investigation by the Christchurch City Council to increase its traffic capacity and upgrade its earthquake resistance. A contract was let in 2010 to undertake these works.
Surviving the September 2010 Darfield earthquake undamaged, the bridge fell victim to the February 2011 Christchurch earthquake with extensive liquefaction and soil lateral spread occurring at the site, displacing the abutments and piers inwards towards the centre of the river. After extensive investigation into options for recovering the bridge, the decision was finally taken to replace the bridge with a new structure.
This paper outlines the initial design to widen and seismically upgrade the original bridge, the damage sustained by the bridge from the Christchurch earthquake and measures instituted to stabilise the bridge as a result of that damage, and focuses particularly on the design now developed for the replacement structure. The significant issues involved in achieving earthquake resistance at a highly liquefiable site and in constructing in an environment of ongoing earthquake activity are discussed.
Anthocyanin Profiling Using UV-Vis Spectroscopy and Liquid Chromatography Mass Spectrometry
Authors: Saha Supradip , Singh Jashbir , Paul Anindita , Sarkar Rohan , Khan Zareen , Banerjee Kaushik 
Published: August 2019

Abstract
Background: As a powerful antioxidant and natural colorant, anthocyanins are being used increasingly as a component of food supplements and nutraceutical products. Hence, its characterization is a prerequisite for further exploration of its nutraceutical potential. UV-Vis and MS are the two important techniques, which have been largely employed for the qualitative and quantitative determination of anthocyanins. However, a comprehensive review of the applications of these techniques in literature is scarce. Objective: This paper aims to review the utilization of UV-Vis spectral data as well as mass spectral data for characterization and putative identification of anthocyanins with approaches of quantification. Methods: The techniques described in literature have been thoroughly reviewed and comparatively evaluated. The complementary approaches of UV-Vis and MS spectra have been discussed for identification and quantification of these compounds. Results: Valuable information about the chemical composition and structure of anthocyanins can be predicted from the UV-Vis spectral data, such as number and type of glycosylation as well as absence or presence of acylation, to name a few. It is also pointed out that for their structural confirmation, selectivity of mass detectors with unit and high-resolution analysis could be effective. Conclusions: The combination of LC-MS with UV-Vis spectroscopy provides complementary information on structural details of anthocyanins. In case the analytical reference standards are available, a triple quadrupole mass spectrometer provides selectivity and quantitative sensitivity in analysis. On the other hand, high-resolution MS analysis provides valuable information for tentative identification during nontarget screening of compounds when the reference standard is not available. Highlights: This paper reviews the applications of UV-Vis spectroscopy and LC-MS for qualitative and quantitative analysis of anthocyanins.
Analyse des discours réflexifs produits dans un dispositif de formation en alternance en éducation physique
Authors: Lenzen Benoît , Poussin Bernard 
Published: August 2019

Cette recherche porte sur les discours réflexifs produits par des étudiants en formation initiale à l’enseignement de l’éducation physique, dans le cadre d’un dispositif de formation en alternance cherchant à orienter leur réflexivité vers des problématiques didactiques. Ces discours réflexifs se caractérisent par (a) une certaine normativité, inhérente à l’approche « normative » du développement professionnel sous-jacente au dispositif, et (b) une forte présence de dimensions didactiques, avec toutefois une prise en compte limitée de l’activité motrice des élèves dans les situations d’apprentissage complexes. Ces résultats soulignent l’intérêt de programmer, dès la formation initiale, des dispositifs de formation en alternance incluant un outillage conceptuel en didactique. Ils pointent également la nécessité d’une formation spécifique à la lecture de l’activité des élèves.
L’ascendance du maître, ou l’empreinte théorique d’Ivan Wyschnegradsky sur Régime 11, Type A (1978) de Bruce Mather
Authors: Bazin Paul 
Published: August 2019

Le compositeur canadien Bruce Mather a fait la rencontre d’Ivan Wyschnegradsky en 1974, quelques années seulement avant le décès de celui-ci. L’amitié qui naît alors entre les deux hommes mène d’abord au premier enregistrement commercial de la musique de Wyschnegradsky par le duo Mather-LePage, puis à la première oeuvre microtonale signée par Mather, Régime 11, Type A (1978), composée pour une formation de deux pianos complémentaires accordés à distance d’un quart de ton. Cet article fait d’abord le survol de certains principes théoriques développés par Wyschnegadsky, relate ensuite la relation qu’il a partagée avec Mather, et propose finalement une analyse de l’ouverture de Régime 11, Type A, dans laquelle le principe d’espaces non-octaviants est repris par celui, qui, aujourd’hui encore, se considère comme le disciple du maître russe.
