Authors: Montesinos‐López Osval A. , Luna‐Vázquez Francisco Javier , Montesinos‐López Abelardo , Juliana Philomin , Singh Ravi , Crossa José
Published: August 2018

The Item‐Based Collaborative Filtering for Multitrait and Multienvironment Data (IBCF.MTME) package was developed to implement the item‐based collaborative filtering (IBCF) algorithm for continuous phenotypic data in the context of plant breeding where data are collected for various traits and environments. The main difference between this package and the other available packages that can implement IBCF is that this one was developed for continuous phenotypic data, which cannot be implemented in the current packages because they can implement IBCF only for binary and ordinary phenotypes. In the following article, we will show how to both install the package and use it for studying the prediction accuracy of multitrait and multienvironment data under phenotypic and genomic selection. We illustrate its use with seven examples (with information from two datasets, Wheat_IBCF and Year_IBCF, which are included in the package) comprising multienvironment data, multitrait data, and both multitrait and multienvironment data that cover scenarios in which breeding scientists are interested. The package offers many advantages for studying the genomic‐enabled prediction accuracy of multitrait and multienvironment data, ultimately helping plant breeders make better decisions.

Published: August 2018

The atmospheric temperatures of the ultra-hot Jupiter KELT-9b straddle the transition between gas giants and stars, and therefore between two traditionally distinct regimes of atmospheric chemistry. Previous theoretical studies assume the atmosphere of KELT-9b to be in chemical equilibrium. Despite the high ultraviolet flux from KELT-9, we show using photochemical kinetic calculations that the observable atmosphere of KELT-9b is predicted to be close to chemical equilibrium, which greatly simplifies any theoretical interpretation of its spectra. It also makes the atmosphere of KELT-9b, which is expected to be cloud-free, a tightly constrained chemical system that lends itself to a clean set of theoretical predictions. Due to the lower pressures probed in transmission (compared to emission) spectroscopy, we predict the abundance of water to vary by several orders of magnitude across the atmospheric limb depending on temperature, which makes water a sensitive thermometer. Carbon monoxide is predicted to be the dominant molecule under a wide range of scenarios, rendering it a robust diagnostic of the metallicity when analyzed in tandem with water. All of the other usual suspects (acetylene, ammonia, carbon dioxide, hydrogen cyanide, methane) are predicted to be subdominant at solar metallicity, while atomic oxygen, iron, and magnesium are predicted to have relative abundances as high as 1 part in 10,000. Neutral atomic iron is predicted to be seen through a forest of optical and near-infrared lines, which makes KELT-9b suitable for high-resolution ground-based spectroscopy with HARPS-N or CARMENES. We summarize future observational prospects of characterizing the atmosphere of KELT-9b.

We present recent ALMA observations of the CO (1–0) and CO (3–2) emission lines in the brightest cluster galaxy of RXC J1504.1−0248, which is one of the most extreme cool core clusters known. The central galaxy contains

of molecular gas. The molecular gas morphology is complex and disturbed, showing no evidence for a rotationally supported structure in equilibrium. A total of 80% of the gas is situated within the central 5 kpc of the galactic center, while the remaining gas is located in a 20 kpc long filament. The cold gas has likely condensed out of the hot atmosphere. The filament is oriented along the edge of a putative X-ray cavity, suggesting that active galactic nucleus activity has stimulated condensation. This is energetically feasible, although the morphology is not as conclusive as systems whose molecular filaments trail directly behind buoyant radio bubbles. The velocity gradient along the filament is smooth and shallow. It is only consistent with freefall if it lies within 20° of the plane of the sky. The abundance of clusters with comparably low velocities suggests that the filament is not freefalling. Both the central gas and filamentary gas are coincident with bright UV emission from ongoing star formation. Star formation near the cluster core is consistent with the Kennicutt–Schmidt law. The filament exhibits increased star formation surface densities, possibly resulting from either the consumption of a finite molecular gas supply or spatial variations in the CO-to-H2 conversion factor.
Magnetic Mirroring and Focusing of Cosmic Rays
Authors: Silsbee Kedron , Ivlev Alexei V. , Padovani Marco , Caselli Paola
Published: August 2018

We study the combined impact of magnetic mirroring and focusing on the ionization by cosmic rays (CRs) in dense molecular clouds and circumstellar disks. We show that for effective column densities of up to ∼1025 cm−2 (where ionization is the main mechanism of energy loss by CRs) the two effects practically cancel each other out, provided the magnetic field strength has a single peak along field lines. In this case the ionization rate at a given location is controlled solely by attenuation of interstellar CRs due to energy losses. The situation is very different in the presence of magnetic pockets—local minima of the field strength, where the CR density and thus ionization can be reduced drastically. We obtain simple analytical expressions allowing accurate calculation of the ionization rate in these regions.

Authors: Norphanphoun Chada , Raspé Olivier , Jeewon Rajesh , Wen Ting-Chi , Hyde Kevin D.
Published: August 2018

Mangroves are relatively unexplored habitats and have been shown to harbour a number of novel species of fungi. In this study, samples of microfungi were collected from symptomatic branches, stem and leaves of the mangrove species Xylocarpusgranatum, X.moluccensis and Lumnitzeraracemosa and examined morphologically. The phylogeny recovered supports our morphological data to introduce three new species, Cytosporalumnitzericola, C.thailandica and C.xylocarpi. In addition, a combined multi-gene DNA sequence dataset (ITS, LSU, ACT and RPB2) was analysed to investigate phylogenetic relationships of isolates and help in a more reliable species identification.

Authors: Pernicová Radka
Published: August 2018

In a previous study, we presented new method measurement rheological properties of hydrophobized plaster in dependence of hardening time. Influence of external temperature on pozzolana plaster is analyzed in this paper, especially plasticity and workability of paste. Main aim of rheological test is determination of flow curves, obtained by applying a succession of constant strain rates for short times at the temperature 10°C and 30°C. Base on the performed experiments, it can be concluded that the temperature have very significant influence on rheological properties of plasters. With an increase in temperature, the application time of the mixture is shorter, from hour to minutes. A comparative measurement with pure lime plaster was done as well.

Published: August 2018

Decision on repairs or strengthening of existing structures with special focus on heritage structures or structures with areas where people may congregate has to be based on detail technical survey according to ISO 13822 and ISO 2394.
The extent of structural intervention has to be always well planned taking into account economic, societal and environmental aspects. It is necessary to consider whether instead of significant structural intervention which could lead to unneeded economical loss of existing structures or also to the loss of heritage value of historic monuments, it is not better to make optimisation of structural intervention and accept the procedure for effective risk management.

Non-Destructive Schmidt Rebound Hammer Evaluation of the Degradation of Concrete Exposed to Elevated Temperatures
Authors: Rozsypalová Iva , Daněk Petr , Sachr Jiří , Karel Ondřej
Published: August 2018

Concrete suffers significant changes in its internal structure due to fire exposition. Chemical and physical transformations cause further changes in its properties [1]. The research focuses on non-destructive Schmidt rebound hammer testing of experimental concrete panels exposed to high temperature. Five concrete panels with the dimensions of 2300 × 1300 × 150 mm were made from concrete of ordinary fire-resistance. According to the standard temperature curve in EN 1991-1-2 [2], the specimens were heated up to the target temperature (550, 600, 800 and 1000 °C) and afterwards, the given thermal load was maintained for 60 more minutes. The equation of the standard temperature curve represents a common fire by which a building structure may be affected in rare cases. The rebound hammer SilverSchmidt L and Original Schmidt N was used for determining the rebound number. Rebound number area charts of all experimental panels were created in order to identify most damaged areas of the concrete due to the effects of high temperatures. Differences between values of destructive and non-destructive compressive strength were determined.

Authors: Anton Ondřej , Komárková Tereza , Heřmánková Věra
Published: August 2018

Despite efforts to maintain quality during the construction of reinforced concrete structures, it is relatively common for improper reinforcement to be used, contradicting the project, which can lead to serious structural defects. It is then up to non-destructive testing methods to prove these defects. The key is the choice of the appropriate method and equipment, both in terms of achieving the necessary results and the possibility of their documentation. In recent years, there has been a significant progress in the development of non-destructive methods for the diagnosis of reinforcement and modernization of the technologies used so far, especially in the field of GPR and electromagnetic methods. At the same time, however, for a number of reasons, major limitations appear in the area of a conventional method of radiography. This contribution focuses on the current state of the problem, and it demonstrates the applicability of individual methods and their limitations given by their physical principles and technical solutions on a set of practical examples.

Published: August 2018

The paper is concerned with the technical aspects of the appraisal and retrofitting process of fire damaged reinforced concrete structures. The assessment of fire damaged structures is carried out along lines similar to those of the appraisal of existing structures. In practice, constructions are most often assessed by destructive tests in-situ and on core bore specimens. In addition to destructive tests, damaged structures are also assessed by non-destructive ones. The present paper shows the use of non-destructive methods of measurement using the acoustic-emission and impact-echo methods. Acoustic emission provides valuable data on the structural integrity of a material. This method has a significant potential to be used for in-situ monitoring and evaluation of the current state of structures. An impact-echo method is based on impact-generated stress waves that propagate through concrete and are reflected by internal flaws and external surfaces. Impact-echo can be used to determine the location and extent of flaws such as crack delamination, voids, honeycombing and deboning in plain, reinforced, and post-tensioned concrete structures. The paper presents a possible rehabilitation plan based on the potential results obtained by these non-destructive methods.

Utilization of Fly Ash Contaminated by SNCR Flue Gas Denitrification into Polymer Epoxy Anchor
Authors: Žlebek Tomáš , Hodul Jakub , Drochytka Rostislav
Published: August 2018

The paper deals with the possibility of using two different types of fly ash contaminated by flue gas denitrification (Selective Non-Catalytic Reduction (SNCR)) as a filler into the polymer anchor based on epoxy resin. Due to the problematic use of contaminated fly ash in silicate materials, the use of such fly ash in polymer materials seems to be effective because by mixing with polymers such as polyester and epoxy resins, toxic gas ammonia (NH3) does not release. Determination of optimal percentage of filling by the fly ash was performed in order to achieve the best possible physical and mechanical properties of the epoxy anchor material. It was found out that the 45% addition of both used of contaminated fly ashes seems to be the most appropriate, when the polymer anchor material exhibited better tensile properties than reference anchors containing quartz sand Dorsilit. Furthermore, it was found that the optimal addition of contaminated fly ash also positively influenced the maximum anchoring force found in the tug test. Detailed connection of anchor material with anchored bar and concrete was observed on tomography images.

Published: August 2018

Context: 

The advent of Web-based sports injury surveillance via programs such as the High School Reporting Information Online system and the National Collegiate Athletic Association Injury Surveillance Program has aided the acquisition of football injury data.

Objective: 

To describe the epidemiology of injuries sustained in high school football in the 2005–2006 through 2013–2014 academic years and collegiate football in the 2004–2005 through 2013–2014 academic years using Web-based sports injury surveillance.

Design: 

Descriptive epidemiology study.

Setting: 

Online injury surveillance from football teams of high school boys (annual average = 100) and collegiate men (annual average = 43).

Patients or Other Participants: 

Football players who participated in practices and competitions during the 2005–2006 through 2013–2014 academic years in high school or the 2004–2005 through 2013–2014 academic years in college.

Main Outcome Measure(s): 

Athletic trainers collected time-loss injury (≥24 hours) and exposure data. Injury rates per 1000 athlete-exposures (AEs), injury rate ratios (IRRs) with 95% confidence intervals (CIs), and injury proportions by body site and diagnosis were calculated.

Results: 

The High School Reporting Information Online system documented 18 189 time-loss injuries during 4 539 636 AEs; the National Collegiate Athletic Association Injury Surveillance Program documented 22 766 time-loss injuries during 3 121  476 AEs. The injury rate was higher among collegiate than high school (7.29 versus 4.01/1000 AEs; IRR = 1.82; 95% CI = 1.79, 1.86) athletes. Most injuries occurred during competitions in high school (53.2%) and practices in college (60.9%). The competition injury rate was higher than the practice injury rate among both high school (IRR = 5.62; 95% CI = 5.46, 5.78) and collegiate (IRR = 6.59; 95% CI = 6.41, 6.76) players. Most injuries at both levels affected the lower extremity and the shoulder/clavicle and were diagnosed as ligament sprains and muscle/tendon strains. However, concussion was a common injury during competitions among most positions.

Conclusions: 

Injury rates were higher in college than in high school and higher for competitions than for practices. Concussion was a frequent injury sustained during competitions, which confirms the need to develop interventions to mitigate its incidence and severity.

Eye state classification from electroencephalography recordings using machine learning algorithms
Authors: Piatek Łukasz , Fiedler Patrique , Haueisen Jens
Published: August 2018

Background and Objectives:

Current developments in electroencephalography (EEG) foster medical and nonmedical applications outside the hospitals. For example, continuous monitoring of mental and cognitive states can contribute to avoid critical and potentially dangerous situations in daily life. An important prerequisite for successful EEG at home is a real-time classification of mental states. In this article, we compare different machine learning algorithms for the classification of eye states based on EEG recordings.

Materials and Methods:

We tested 23 machine learning algorithms from the Waikato Environment for Knowledge Analysis toolkit. Each classifier was analyzed on four different datasets, since two separate approaches - called sample-wise and segment-wise - in combination with raw and filtered data were applied. These datasets were recorded for 27 volunteers. The different approaches are compared in terms of accuracy, complexity, training time, and classification time.

Results:

Ten out of 23 classifiers fulfilled the determined requirements of high classification accuracy and short time of classification and can be denoted as applicable for real-time EEG eye state classification.

Conclusions:

We found that it is possible to predict eye states using EEG recordings with an accuracy from about 96% to over 99% in a real-time system. On the other hand, we found no best, universal method of classifying EEG eye states in all volunteers. Therefore, we conclude that the best algorithm should be chosen individually, using the optimal classification accuracy in combination with time of classification as the criterion.

Abstract. Numerical models are a useful tool for studying marine ecosystems and associated biogeochemical processes in ice-covered regions where observations are scarce. To this end, CSIB v1 (Canadian Sea-ice Biogeochemistry version 1), a new sea-ice biogeochemical model has been developed and embedded into the Nucleus for European Modelling of the Ocean (NEMO) modelling system. This model consists of a three-compartment (ice algae, nitrate, and ammonium) sea-ice ecosystem and a two-compartment (dimethylsulfoniopropionate and dimethylsulfide) sea-ice sulfur cycle which are coupled to pelagic ecosystem and sulfur-cycle models at the sea ice-ocean interface. In addition to biological and chemical sources and sinks, the model simulates the horizontal transport of biogeochemical state variables within sea ice through a one-way coupling to a dynamic-thermodynamic sea-ice model (LIM2). This paper describes technical aspects of implementing sea-ice biogeochemistry into NEMO and provides discussion on the results of several model experiments. Results of the reference simulation were evaluated by comparing the model outputs to observations and previous modelling studies. Additional simulations were conducted to assess the model sensitivity to 1) the temporal resolution of the snowfall forcing data, 2) the representation of light penetration through snow, 3) advective and eddy-diffusive horizontal transport of sea-ice biogeochemical state variables, and 4) light attenuation by ice algae. The sea-ice biogeochemical model has been developed within the generic framework of NEMO to facilitate its use within different configurations and domains, and can be adapted for use with other NEMO-based submodels such as LIM3 and PISCES.
A systematic approach to offshore wind turbine jacket predesign and optimization: geometry, cost, and surrogate structural code check models
Authors: Häfele Jan , Damiani Rick R. , King Ryan N. , Gebhardt Cristian G. , Rolfes Raimund
Published: August 2018

Abstract. The main obstacles in preliminary design studies or optimization of jacket
substructures for offshore wind turbines are high numerical expenses for
structural code checks and simplistic cost assumptions. In order to create a
basis for fast design evaluations, this work provides the following: first, a
jacket model is proposed that covers topology and tube sizing with a limited
set of design variables. Second, a cost model is proposed that goes beyond
the simple and common mass-dependent approach. And third, the issue of
numerical efficiency is addressed by surrogate models for both fatigue and
ultimate limit state code checks. In addition, this work shows an example
utilizing all models. The outcome can be utilized for preliminary design
studies and jacket optimization schemes. It is suitable for scientific and
industrial applications.

el presente artículo se propone abordar el papel del olvido en la obra de Platón. Para ello toma como textos principales de trabajo los diálogos en que se expone la doctrina de la anamnesis y a partir de ellos, pero atendiendo también a algunos otros diálogos, se exploran las conexiones entre el olvido y otros temas platónicos como el lenguaje, la memoria, la experiencia o el amor, con el fin de aclarar las relaciones de dependencia que puedan encontrarse entre ellos. de este modo se intenta descubrir en el olvido un sentido filosófico que no resulte desdeñable en comparación con el sentido y la relevancia concedidos desde antiguo a la anamnesis, dado que uno y otra no se pueden separar.
El cuerpo, el artificio, los sonámbulos. Sobre el uso spinoziano de la experiencia como crítica de la concepción cartesiana de la libertad
Authors: Lomba Falcón Pedro
Published: August 2018

En el presente artículo se estudia una de las estrategias teóricas empleadas por Spinoza para consolidar sus posiciones frente a aquellas que más eficazmente impiden su comprensión. Así, recurre también él a la experiencia inmediata o irreflexiva –utilizada por Descartes para fundamentar su defensa del libre albedrío, o la distinción de alma y cuerpo– pero para demostrar que con ella se prueban algunas tesis estrictamente anticartesianas. Aquellas que expresan el núcleo del spinozismo.
El don de lo no dado: la fenomenología de la donación de Jean-Luc Marion ante el “hay” levinasiano
Authors: Llorente Jaime
Published: August 2018

La fenomenología de la donación de Jean-Luc Marion constituye una de las más destacadas tentativas de fundar una teoría universal de lo fenoménicamente dado en su totalidad en el marco del pensamiento filosófico contemporáneo. El propósito de este estudio es aplicar las categorías principales de esta teoría fenomenológica acerca del don al singular tipo de fenómeno representado por el puro existir indeterminado y anónimo al cual se refiere Emmanuel Levinas en sus escritos tempranos –y también posteriormente– mediante la designación de il y a (“hay”). Se trata, por tanto, de examinar los múltiples modos de donación específicos propios del “hay” impersonal, así como su relación paradójica tanto con el donador como con el receptor de tal don, en orden a mostrar la posibilidad de una “tercera vía” de la investigación fenomenológica. Una vía igualmente alejada de la tradicional concepción occidental del Ser como “presencia estable” y de la propuesta levinasiana orientada a sustituir la ontología por la ética en cuanto “filosofía primera”.
Enfermedad y caída en Albert Camus
Authors: Montero Bosch David
Published: August 2018

Este artículo está centrado en el tema de la enfermedad en Albert Camus. Se hace especial hincapié en su última novela publicada, La Chute. El tema de la enfermedad es usualmente enfocado en relación con la muerte y la finitud en la literatura y la filosofía. En este artículo se enfoca en relación con la experiencia existencial de la enfermedad como decaimiento de la plenitud vital. El caso de Albert Camus es especialmente significativo por su condición de enfermo crónico y porque la enfermedad ocupa un lugar destacado en sus obras literarias. Aquí se ha escogido La Chute porque ofrece una riqueza de niveles interpretativos sin parangón en la obra camusiana. Se propondrá dos niveles distintos de lectura. La distinción y análisis de estos dos niveles permitirá una conclusión más matizada de las relaciones del autor con su obra y de la polémica en torno al papel social del intelectual. La conclusión de este artículo difiere tanto de los críticos que se limitan a considerar la obra en función de su polémica con Jean-Paul Sartre, cuanto de los que la interpretan como una confesión enmascarada.
EDUCAÇÃO MATEMÁTICA E PAULO FREIRE: ENTRE VESTÍGIOS E IMBRICAÇÕES
Authors: Forner Regis , Oechsler Vanessa , Honorato Alex Henrique Alves
Published: August 2018

Este trabalho analisa os caminhos traçados pelos oito pesquisadores entrevistados de uma dissertação de mestrado (FORNER, 2005), com a finalidade de identificar possíveis sinergias entre o legado de Paulo Freire e tendências em Educação Matemática. Para isso, realiza-se uma busca a partir da leitura do Currículo Lattes de cada um dos oito sujeitos, focando nas teses e dissertações orientadas e defendidas a partir de 2004 (ano em que as entrevistas foram realizadas e transcritas). Como resultado deste estudo, tem-se que, em muitas das pesquisas consultadas, as teorias de Paulo Freire apenas as perpassam (vestígios) e em outras, como as de Modelagem Matemática, Etnomatemática e aquelas embasados na Educação Matemática Crítica, há fortes interligações (imbricações).
EDUCAÇÃO PROGRESSISTA E DIREITOS EDUCACIONAIS DE ADOLESCENTES E JOVENS EM CUMPRIMENTO DE MEDIDAS SOCIOEDUCATIVAS
Authors: Gonçalves Fabíola Mônica da Silva
Published: August 2018

Este tem como objetivos (i) identificar possíveis relações entre o ECA (1990) e o Sinase (2012) em termos das orientações legais sobre os direitos educacionais e as medidas socioeducativas para a população brasileira de adolescentes e de jovens, e; (ii) aproximar o pensamento pedagógico de Paulo Freire acerca de uma educação emancipatória em contextos institucionais de ressocialização de adolescentes e jovens em conflito com a lei. Para tal, utilizou-se os procedimentos técnicos de análise documental e levantamento bibliográfico (GIL, 2008). Como conclusão, observou-se um descompasso entre os dispositivos legais analisados e a situação real das medidas socioeducativas, e ao mesmo tempo, como a pedagogia freiriana pode lançar luz para a busca de mudança desta realidade social desumana. (FREIRE, 2008; 2004; 2001, 1992).Unv
OUTRA LINGUAGEM, OUTRA ALFABETIZAÇÃO: SENTIDOS DA EDUCAÇÃO EMANCIPADORA EM PAULO FREIRE
Authors: Da Silva Ramos Bruna Sola , Ladeira Aires Franciane Sousa
Published: August 2018

O propósito deste ensaio é refletir sobre outra linguagem e outra alfabetização como forma de expressar sentidos sobre a educação emancipadora, a partir da perspectiva crítica de Paulo Freire. Como processo, movimento, acontecimento e interação, a linguagem é percebida para além de um sistema abstrato e estático. Como uma práxis vinculada à criticidade, ao ato político, à autonomia, à libertação, à conscientização, e principalmente, à humanização, a alfabetização é assumida para além do processo de ler e escrever códigos. Nesse viés, a alfabetização emancipadora, não sendo um processo mecanicista, revela potencialidades para a conscientização, enfatizando a leitura da palavramundo, com o intuito de que educadores e educandos possam “ser mais”.
EMANCIPAR OU NATURALIZAR? PEDOFILIZAÇÃO E EDUCAÇÃO SEXUAL A PARTIR DA PROBLEMATIZAÇÃO DAS NOVINHAS
Authors: Silva Fernando Guimarães Oliveira da , Oliveira Márcio De , Maio Eliane Rose
Published: August 2018

A violência sexual contra crianças e adolescentes é uma discussão necessária para a sociedade do século XXI. Propagada intensamente pelos meios midiáticos (internet, televisão etc.), deixa marcas traumáticas nas suas vítimas. Objetivamos discutir a pedofilização como uma prática que têm diferentes estilos musicais como um artefato cultural que a legitima. Utilizamos da pesquisa bibliográfica, problematizando seis letras de músicas que, visivelmente, elencam a criança e a adolescente – sob o codinome de ‘novinha’ – como objeto de desejo de pessoas de mais idade. Vislumbramos com a educação sexual, uma alternativa para movimentar estratégias pedagógicas contra a cultura de consumo do corpo de meninas.
LINGUÍSTICA DE CORPUS E FRASEOLOGIA:UM ESTUDO DAS COLOCAÇÕES COM “FEITO” EM GRANDE SERTÃO: VEREDAS
Authors: PIMENTA Ana Paula Correa , NOVODVORSKI Ariel
Published: August 2018

Com base no pressupostos da Linguística de Corpus, este artigo propõe uma análise léxico-gramatical e semântica das unidades fraseológicas, mais especificamente as colocações com a palavra “feito” que denotam sentido de comparação, na obra Grande Sertão: Veredas (1994)de João Guimarães Rosa. Para tanto, buscou-se fundamentar em Corpas Pastor (1996) para a discussão acerca das unidades fraseológicas, em Halliday (1994) sobre as relações entre o léxico, a gramática e o estrato semântico, e em Berber Sardinha (2004, 2009) a respeito da Linguística de Corpus.Os resultados deste estudo ressaltam a importância de se considerar os elementos linguísticos como parte preponderante da história e da cultura de um povo, bem como a relevância de se evidenciar a considerável contribuição que a Linguística de Corpus tem trazido ao estudo da Fraseologia (especialmente, com corpus literário) no Brasil.
UMA ANÁLISE DE DISCURSO CRÍTICA EM ASPECTOS DE LINGUAGEM E DE RECURSOS PERSUASIVOS NO SLOGAN VOCÊ MUDA, A GENTE CUIDA, DA NATURA PLANT SHAMPOO
Authors: PAIVA Francisco Jeimes de Oliveira
Published: August 2018

Nesta pesquisa, procuramos analisar os aspectos da linguagem e os recursos de persuasão na produção discursiva em peças publicitárias de uma propaganda de produto anunciado pela indústria cosmética Natura. Essa propaganda veiculada nacionalmente, chama-se “Natura Plant Shampoo” e tem como slogan propagandístico: “Você muda, a gente cuida”. Ela foi selecionada por fugir do padrão de propaganda mais corrente na mídia. Ademais, verificou-se a presença de marcas de persuasão resultante dos efeitos de sentidos produzida pela relação multimodal entre linguagem verbal e não-verbal e o contexto social e ideológico transmitido, sobretudo, na mídia televisiva. Ademais, verificamos que as concepções e os aspectos socioculturais se adequam em consonância com a supremacia das práticas discursivas das classes dominantes em função do acesso aos bens culturais, sendo que a indústria da publicidade tem focado numa visão holística de elementos culturais, discursivos, patrimoniais que revelam o interesse pelo consumo em razão de estratégias persuasivas, portanto, o sujeito do mundo pós-moderno é o sujeito do ato de práticas sociais, em consequência, dos conflitos provindos de seus próprios atos, propenso à angústia e culpa que podem lhe causar suas próprias escolhas.
ANÁLISE À LUZ DO CONSTRUTO DE CRENÇAS E FORMAÇÃO DOCENTE DE LÍNGUAS: O PROCESSO DE APRENDIZAGEM DE LÍNGUA INGLESA PRESENTE EM NARRATIVAS DE DOCENTES

Published: August 2018

Objetivou-se, nesta pesquisa, investigar as crenças de professores sobre o processo de aprendizagem de Língua Inglesa a partir de suas narrativas de aprendizagem. Para atingir este objetivo, a investigação teve como arcabouço teórico diferentes discussões linguísticas e socioculturais relacionadas à Língua Inglesa (LI) na era da globalização, conceito de crenças e formação docente de línguas. Trata-se de uma pesquisa qualitativo-interpretativista (BOGDAN & BIKLEN, 1994; ANDRÉ, 1995), cujo corpus foi constituído de narrativas de aprendizagem de Língua Inglesa de professores disponíveis no banco de dados do projeto “Aprendendo com Memórias de Falantes e Aprendizes de Língua Estrangeira” (AMFALE), da Faculdade de Letras (FALE), da Universidade Federal de Minas Gerais (UFMG). Os resultados da análise enfatizam a necessidade do repensar de políticas de formação de professores de Línguas no Brasil, com vistas a uma possível (re)formulação das mesmas, no intento de encontrar subsídios inovadores para o enfrentamento dos desafios presentes, hoje, no ensino escolarizado brasileiro.
