Published: September 2020

Este artículo presenta los resultados de un proyecto de investigación desarrollado en la Facultad de Ingeniería y Ciencias Básicas de la Fundación Universitaria Los Libertadores, Bogotá. cuyo objetivo fue describir los efectos y las experiencias de la incorporación de la aplicación “Calculadora Gráfica” de GeoGebra sobre el aprendizaje de la noción de límite a partir de la integración de dispositivos móviles al aula de clase. Se empleó un diseño explicativo secuencial con el ánimo de validar la hipótesis relacionada con una influencia positiva del aprovechamiento de teléfonos inteligentes y tabletas en el desempeño académico. En la etapa cuantitativa se realizó un diseño experimental de cuatro grupos de Solomon y durante la etapa cualitativa se aplicó un test actitudinal y se desarrollaron entrevistas semiestructuradas con estudiantes que participaron del tratamiento con la aplicación móvil. Los resultados obtenidos en el postest por los grupos experimentales superaron a los obtenidos por los grupos control que participaron de una intervención mediada por recursos didácticos tradicionales. Los estudiantes que recibieron el tratamiento experimental demostraron mayor interés y motivación por el aprendizaje del tema abordado, por lo que se puede inferir que la integración de dispositivos móviles en el aula promueve otras formas innovadoras de aprender cálculo.
T-overlap T-migrative Functions: a generalization of migrativity in t-overlap functions
Authors: Zapata Ceballos Hugo Alain , Bustince Humberto , Dimuro Graçaliz Pereira
Published: September 2020

This paper introduces a generalization of migrative functions by extending the conditions of the product operation applied in the variables. More specifically, instead of requiring to multiply the variable x by a real number x3B1; in this work we operate this x3B1; number with the variables according to a t-norm. We call such generalization as a t-migrative function with respect to such t-norm. Then we analyze the main properties of t-migrative t-overlap functions and introduce some construction methods.
Estimating Market Expectations for Portfolio Selection Using Penalized Statistical Models
Authors: Valencia-Arboleda Carlos Felipe , Segura-Acosta Diego Hernan
Published: September 2020

The portfolio selection problem can be viewed as an optimization problem that maximizes the risk–return relationship. It consists of a number of elements, such as an objective function, decision variables and input parameters, which are used to predict expected returns and the covariance between the said returns. However, the real values of these parameters cannot be directly observed; thus, estimations based on historical data are required. Historical data, however, can often result in modelling errors when the parameters are replaced by their estimations. We propose to address this by using some regularization mechanisms in the optimization.  In addition, we explore the use of implicit information to improve the portfolio performance, such as options market prices, which are a rich source of investor expectations. Accordingly, we propose a new estimator for risk and return that combines historical and implicit information in the portfolio selection problem. We implement the new estimators for the mean-VAR and mean-VaR2 problems using an elastic-net model that reduces the risk of all estimations performed. The results suggest that the model has a good out-of-sample performance that is superior to models with pure historical estimations.

Authors: Maleev D , Isaev A , Petrova Ju , Zalyapin V , Shevtsov A , Korableva Yu
Published: September 2020

Aim. The article aims to assess the body reserves of ski racers who develop local-regional muscle endurance (LRME), statokinetic and hypoxia resistance. Materials and methods. 15–16-year-old highly skilled ski-racers (I, II category, candidates for master of sports) with sports experience of 5–7 years (n = 12) were examined. The following equipment was used to assess athletic fitness and sports performance: T 2100 GE treadmill system, CardioSoft diagnostic system (USA), HYPOXICO Everest Summit II altitude generator (USA), Angio Scan-01 P pulse oximeter sensor (Russia). Statistical analysis was performed using the SPSS information processing package. Results. The effect of techniques for developing LRME and hypoxia resistance on sports performance has been established. A generalized ranking of competitive performance is constructed and a regression model is described that establishes the dependence of sports performance on morphofunctional and metabolic statuses. The key indicators of morphofunctional and metabolic statuses were compared in athletes who used the methods for developing LRME and hypoxia resistance. Criteria are established for successful performance in sports reserve training, promising cross-country skiers, the modeling of status indicators with well-established technologies while maintaining the functional and metabolic potential and the level of health. Conclusion. The results of the study showed the effectiveness of combined technologies in sports training and allowed to identify markers of functional and metabolic statuses. The proposed technologies allowed to enhance adaptation and identify status markers. This made it possible to improve performance in the conditions of LRME and statokinetic and hypoxia resistance. Forecasting sports results allows regulating athletic fitness and making timely corrections to ensure successful sports performance.

Authors: Nur Azza Kamala Kan , Susianti Noor Alia , Agustin Rizki Puji , Khasanah Uswathon , Andarwanti Lina , Yuniatun Widya
Published: September 2020

Latar Belakang: Hipokalemia merupakan gangguan elektrolit yang sering terjadi. Hipokalemia berat dapat mengancam jiwa. Koreksi hipokalemi yang tepat dan cepat dapat mencegah komplikasi yang membahayakan jiwa. Salah satu intervensi yang dapat dilakukan adalah dengan pemberian KCl melalui akses vena perifer, tetapi KCl memiliki sifat iritatif yang dapat menyebabkan nyeri. Cara yang dapat dilakukan untuk mengurangi nyeri adalah dengan pemberian lidokain intravena. Lidokain merupakan obat anestesi yang dapat diberikan secara intravena dan memberikan efek analgesia. Tujuan: Mengetahui keefektifan lidokain untuk mengurangi nyeri pada pemberian KCl melalui akses vena perifer.Metode: Penelitian ini merupakan uji klinis randomisasi samar berganda melibatkan 37 pasien hipokalemia yang memerlukan koreksi. Pasien terbagi menjadi 21 pasien kelompok perlakuan (mendapatkan lidokain saat koreksi) dan 16 pasien kelompok kontrol (tanpa lidokain) yang kemudian penilaian nyeri menggunakan numering pain rating scale (NPRS) pada pertengahan proses koreksi (2,5 jam) dan akhir koreksi (5 jam).  Hasil: Tidak terdapat perbedaan karakteristik dasar di kedua kelompok pada awal penelitian. Pemberian lidokain terbukti dapat mengurangi terjadinya nyeri dari proses koreksi kalium pada pertengahan proses koreksi dan akhir proses koreksi (p<0,05). Pada progresivitas nyeri, pemberian lidokain mampu mencegah terjadinya nyeri pada 2,5 jam pertama (RR=0,47, 95%IK 0,26-0,85, p=0,01) namun progresivitas nyeri 2,5 jam berikutnya tidak bermakna secara statistik (RR=0,95, 95%IK 0,30-2,99, p>0,05).Kesimpulan: Lidokain dapat mengurangi nyeri selama proses koreksi kalium sehingga dapat dipertimbangkan untuk diaplikasikan dalam praktik klinis.

Authors: Winarko Daryanto Tri , Airlangga Prananda Surya , Rahardjo Eddy
Published: September 2020

Latar Belakang: Penyebab subarachnoid hemorrhage (SAH) non trauma terbanyak adalah pecahnya aneurisma (75%-85%). Hal ini merupakan kondisi yang mengancam jiwa dan memerlukan perawatan neurokritikal, sedangkan delayed cerebral ischemia (DCI) merupakan komplikasi serius dari SAH dan berhubungan dengan hasil neurologis yang merugikan. Vasospasme serebral adalah penyebab utama terjadinya DCI, paling sering terjadi pada hari ke 7-8 setelah perdarahan. Penderita tekanan darah tinggi, perokok, peminum, wanita dan usia 40-60 tahun berisiko menderita aneurysmal subarachnoid hemorrhage (aSAH).Kasus: Terdapat 3 kasus aSAH yang dilaporkan. Kasus pertama dan ketiga tidak mengalami penurunan kesadaran yang menurut skala modifikasi fisher berisiko terjadi vasospasme berskala 2 atau berisiko sedang dan angka mortalitas (menurut Hunt dan Hess) keduanya sebesar 40%. Sedangkan kasus ke 2 terjadi penurunan kesadaran yang mempunyai  risiko terjadi vasospasme berskala 2 yakni berisiko sedang, namun angka mortalitasnya 50%. Ketiga kasus setelah diagnose SAH ditegakkan segera mendapatkan terapi nimodipin untuk pencegahan terjadinya vasospasme disamping status cairan harus euvolemi dan tekanan darah sistole 120-140 mmHg.Pembahasan: aSAH mempunyai angka kematian dan tingkat kecacatan permanen yang tinggi. Aneurisma serebri dapat terdeteksi ketika pecah atau saat pemeriksaan CT scan dan magnetic reconance imaging (MRI) yang tidak disengaja. Kematian biasanya disebabkan oleh cedera neurologis akibat perdarahan awal, perdarahan ulang (rebleeding) dan DCI. Tujuan pengelolaan pecahnya aSAH adalah untuk mencegah terjadinya perdarahan ulang dan DCI dengan menggunakan terapi nimodipin, mempertahankan volume darah normal (euvolume) dan mempertahankan tensi sistolik sekitar 120-140 mmHg.Kesimpulan: Untuk pencegahan aSAH tindakan skrining aneurisma akan lebih baik dan dapat menghemat biaya. Sedangkan pencegahan terjadinya DCI pada aSAH dilakukan dengan pemberian obat nimodipin, mempertahankan sirkulasi darah normal dan tekanan darah sligh hipertensi (120-140 mmHg).
Christoph Jamnitzer’s Speechless Defense of the Goldsmith’s Strengths
Authors: Brisman Shira
Published: September 2020

In 1616, the Nuremberg goldsmith Christoph Jamnitzer completed a commission for one patrician, Ernst Haller von Hallerstein, that served as a gift to another, Jacob Stark von Reckenhoff. In depicting at the cup’s stem the image of the ancient wrestler Milo of Croton carrying a bull, Jamnitzer alluded to an emblem decorating the city hall to pun on the associations with strength in the recipient’s last name. The iconography of the vessel thus bound the owner of the object to the virtues promoted in the building of governance at the same time that it demonstrated the goldsmith’s virtuosic balancing of weight. The cup thus makes visible the material and metaphorical links between the skills of the goldsmith’s craft and the ethics and politics of the free imperial city.
El fenómeno Jorge Yunda en la elección a alcalde de Quito (2019) comprendido desde la teoría del populismo
Authors: Enríquez Eduardo
Published: September 2020

Se busca contribuir al conocimiento sobre el fenómeno del populismo latinoamericano en un caso de política local y también a la comprensión de la política democrática local contemporánea de esa región. Jorge Yunda logró una comprensión privilegiada de los códigos culturales de los sectores populares de la ciudad de Quito ejerciendo dotes comunicativas excepcionales y siendo dueño de un gran conglomerado de medios de comunicación. Eso le permitió llegar a ganar la elección a la alcaldía de la ciudad en 2019. La sorpresa de esa victoria muestra la volátil institucionalidad partidista local y una relacionada pobre conexión de la élite política con grandes sectores de la población de la ciudad en medio de manifestaciones clasistas y racistas en contra de Yunda. Aquello se mira a través de una narrativa analítica del ascenso social y político de Yunda.
La importancia de Radio Sandino durante la revolución nicaragüense (1977-1979)
Authors: AMADOR RODRÍGUEZ BELÉN
Published: September 2020

A través de la literatura existente y desde la Historia Social de la Comunicación, partiendo del concepto “propaganda sandinista”, he analizado la importancia de Radio Sandino, un medio de comunicación clandestino que resultó clave en la victoria del Frente Sandinista de Liberación Nacional (FSLN). Desde 1977 hasta 1979 se produce en Nicaragua una “guerra psicológica”, también denominada “propaganda de guerra” en la que la censutra, que es otro instrumento esencial en el control del flujo de la información y el control del pensamiento, tiene un papel relevante. Los sandinistas, como grupo guerrillero, pretendieron influir en la sociedad para terminar con la dictadura de la dinastía de los Somoza en Nicaragua, y Radio Sandino fue uno de sus instrumentos a nivel de comunicación para conseguirlo.

Laser-induced plasma emission spectroscopy (LIPS): A useful analytical tool for the surface chemical characterization of coated paper materials
Authors: Lucia Lucian A. , Willett Brian , Korppi-Tommola Jouko
Published: September 2020

A nontraditional method for chemical analysis of light weight coated (LWC) grade paper is described. Laser-induced plasma emission spectrometry (LIPS) produces three-dimensional profiles of coatings and fillers. The technique ablates the coating from the top to the paper base with a laser beam. LIPS provides spatial resolution and characterization of the chemical homogeneity of the paper coating and relates that information to the efficiency of the coating method. It provides information on binder migration which is a hindrance for improved stable coatings. Herein, several commercial LWC paper grades and their base papers were analyzed. Pigment identification of light weight paper coatings, coat weight distribution maps, and profiles were obtained. Blade and film coating generate different coating distribution profiles that are detected by LIPS. The phenomenon of binder migration was demonstrated by observing its masking effects on Si spectra. An investigation of filler content in base papers involved analysis of base paper used in LWC grades. The papers represented two different types of formers, but because of confidentiality issues, little else was revealed. A significantly higher amount of filler was observed at the surface of the base stock in Former A than in Former B, as indicated from Mg spectra of the filler.
Towards a better understanding of the mechanical behavior of a fixed bed of eucalyptus charcoal in a blast furnace using a specific compression test

Published: September 2020

The properties of wood charcoal layers have an effect on the performance of small-scale blast furnaces. In order to characterize the mechanical behavior of a fixed bed of eucalyptus charcoal, a specific uniaxial compression test was designed and used with charcoal layers of different characteristics. This layer test has the potential to be standardized, and it made it possible to consider the bulk properties of randomly layout charcoal pieces, which was better adapted than single specimen tests in the fiber direction. A total of eight charcoal layers were prepared with two carbonization temperatures (500 °C and 900 °C), two granularities (10 mm and 20 mm), and two different testing temperatures (20 °C and 300 °C). Characteristic parameters of the compression tests were then determined as the particle size distribution, the mechanical energy, and the mean power. The charcoal produced at 900 °C and with a granularity of 20 mm was more resistant to breakage than the others were, and a high quantity of large particles remained after the tests. Significant correlations existed between the carbonization temperature, granularity, and mechanical power of the compression test. The mechanical power was the main parameter that determined the resistance to breakage of a charcoal bed in compression.
DeCovidation = Deinstitutionalization. Independent Living and Inclusion in the Community
Authors: Genienė Rasa
Published: September 2020

The global coronovirus (Covid-19) pandemic has been revealed what about half of the world’s deaths are recorded in large institutions of the elderly and people with disabilities, and these are later thought to be incentives for states to take active deinstitutionalisation efforts. In order for deinstitutionalisation actions to respond to its ideological origins, which lie in the provisions of the United Nations Convention on the Rights of Persons with Disabilities, in the necessary legal instruments and in clarifying that Member States are responsible. The article reveals how the deinstitutionalisation processes that have already started are implemented and evaluated in Central and Eastern Europe and discusses their problems. Content analysis was used to investigate the Soviet regime, leading to the implementation of official and alternative (shadow) reports on the United Nations Convention on the Rights of Persons with Disabilities.
Photoperiodic stress induces genotype-specific shift in DNA methylation in Tartary
buckwheat

Published: September 2020

Tartary buckwheat, known for its rich source of health beneficial secondary
metabolites, is cultivated in many areas of the world. Among different environmental
factors, photoperiod strongly influence its growth, flowering time, and ultimately the
yield. In this context, epigenetics could contribute significantly in the regulation of
plant response against changing environment. Therefore, with the aim to study the
involvement of DNA methylation in photoperiod mediated plant response, genome-wide DNA
methylation analysis was performed in two accessions (A1 and A2) of Tartary buckwheat
using three photoperiodic treatments, i.e., 10-hr light/day (T1), 12-hr light/day (T2),
and 14-hr light/day (T3). Flowering time and plant fresh weight data revealed that
accessions A1 and A2 prefer T1 and T2 treatments, respectively. Total DNA methylation
ratio increased with the increase in photoperiod in accession A1 but decreased under
same conditions in accession A2. Full methylation increased significantly while
intensive decrease in hemimethylation was noted from T2 to T3 in A1, whereas full
methylation strongly increased and hemimethylation strongly decreased from T1 to T2 in
A2. Overall, the DNA methylation events appeared more frequently than demethylation
events. This study reports for the first time an accession-/genotype specific pattern of
shift in the DNA methylation under different photoperiodic treatments that will pave the
way toward identification of specific genes involved in the regulation of plant response
against photoperiodic stress.

Sintesis dan Karakterisasi Selulosa Termetilasi sebagai Biokomposit Hidrogel
Authors: Nurjannah Neng Rita , Sudiarti Tety , Rahmidar Lena
Published: September 2020

Penggunaan biomaterial di bidang klinis semakin banyak dilakukan, karena biomaterial lebih aman digunakan (tidak toksik) serta ketersediaannya di alam sangat banyak. Salah satu pemanfaatan  biomaterial ini adalah yang berasal serat batang pisang. Serat batang pisang ini merupakan prekursor untuk disintesis menjadi Metil Selulosa (MS) yang bisa digunakan sebagai bahan hidrogel untuk proses penyembuhan luka dan iritasi kulit. Penelitian ini dimulai dari sintesis selulosa mikrobial dari batang pisang dengan menggunakan starter Acetobacter xylinum yang diinkubasi selama 9 hari. Nata yang diperoleh dimurnikan dan dihasilkan selulosa mikrobial. Selulosa mikrobial yang dihasilkan kemudian disintesis menjadi metil selulosa. Metil selulosa disintesis secara swelling, kemudian ditambahkan pelarut dan metilen klorida untuk proses metilasi. Selulosa dan metil selulosa dianalisis FTIR dan dilakukan pengujian pada metil selulosa meliputi warna, titik leleh serta kelarutan, sehingga dapat diperkirakan nilai DS-nya. Hasil karakterisasi FTIR pada selulosa mikrobial terdapat gugus –OH pada bilangan gelombang 3388,93 cm-1 dan gugus -CH pada bilangan gelombang 2931,80 cm-1. Karakterisasi metil selulosa dengan FTIR dapat diketahui dengan munculnya puncak daerah serapan gugus  –CH yang semakin tajam, yaitu pada MS-air dan MS-aseton terdapat gugus –CH masing-masing pada panjang gelombang 2918,30 cm-1 dan 2900,94 cm-1. Metil selulosa hasil sintesis dari batang pisang tidak dapat larut dalam pelarut air dingin (0-15°C), NaOH 4% dan asam asetat glasial. Nilai Derajat Substitusi (DS) MS-aseton 0,912 dan MS-air 0,834, sehingga pelarut aseton lebih baik untuk mengoptimalkan nilai DS pada metil selulosa.

Getting to know a new protocol in hypertension care
Authors: Lundin Mona
Published: September 2020

This study explores the use of a new protocol in hypertension care, in which continuous patient-generated data reported through digital technology are presented in graphical form and discussed in follow-up consultations with nurses. This protocol is part of an infrastructure design project in which patients and medical professionals are co-designers. The approach used for the study was interaction analysis, which rendered possible detailed in situ examination of local variations in how nurses relate to the protocol. The findings show three distinct engagements: (1) teasing out an average blood pressure, (2) working around the protocol and graph data and (3) delivering an analysis. It was discovered that the graphical representations structured the consultations to a great extent, and that nurses mostly referred to graphs that showed blood pressure values, which is a measurement central to the medical discourse of hypertension. However, it was also found that analysis of the data alone was not sufficient to engage patients: nurses' invisible and inclusion work through eliciting patients' narratives played an important role here. A conclusion of the study is that nurses and patients both need to be more thoroughly introduced to using protocols based on graphs for more productive consultations to be established.
Narratives of illness in a Chinese virtual hospital
Authors: Zhang Yu
Published: September 2020

This study explores 60 individual narratives of illness presented in the initiating messages of threads that are posted in a well-known virtual space, ‘Tianya Hospital’ (????), in China. ‘Tianya Hospital’ is a discussion board where website users discuss their own or their loved ones’ health problems with other participants, who may be either health experts or patients with similar illnesses. Adopting the approach of mediated discourse analysis, the study aims to find out what is narrated (i.e., narrative presentation categories), what stance is taken and what the patterns and functions of the narrative presentation and the stance taking are. Some narrative presentation categories identified in this study are to some degree associated with existing face-to-face medical consultation phases, while others are related to a ‘timescale’ frame and the ‘sick role’ concept. The findings also show that the online narratives present not only the description of health problems, but also epistemic and affective stances. Some features of the narrative presentation organization and the stance taking in narratives can perform particular functions, such as serving to legitimize patients’ or patients’ caregivers’ complaints about healthcare services
“(NÃO) LEIA OS COMENTÁRIOS”: A DISPUTA DA NOTÍCIA SOBRE O ASSASSINATO DE MARIELLE FRANCO
Authors: Biar Liana de Andrade , Paschoal Fabiola Valle das Chagas
Published: September 2020

RESUMO O presente artigo procura contribuir para a construção de entendimentos sobre o potencial semiótico dos comentários na interação em plataformas digitais. Toma-se como objeto a repercussão online de um caso notório: o assassinato da vereadora Marielle Franco, ocorrido em 2018. A tarefa analítica desta pesquisa é escrutinar discursivamente uma cauda de 1.600 comentários, entendidos aqui tanto como reentextualizações da própria notícia, quanto como lastros de sua trajetória textual em contextos de circulação variados. Os resultados iluminam os modos como os comentadores contribuem para a produção, expansão e disputa de certos discursos que marcam a polarização ideológica no cenário sócio-político contemporâneo.
“OI, MEU NOME É BETTINA”: A VOZ E A VEZ DO HOMO OECONOMICUS NO NOVO GOVERNO BRASILEIRO
Authors: Lopes Carlos Renato
Published: September 2020

RESUMO O artigo propõe uma leitura do momento inicial do governo de direita ora vigente no Brasil, sugerindo a emergência de uma forma particular de populismo que, sustentada por uma lógica neoliberal de funcionamento da sociedade, constitui terreno fértil para o florescimento de um discurso de empreendedorismo e sucesso financeiro ao alcance de qualquer indivíduo. Tal configuração, que chamamos aqui de populismo neoliberal, promove em sua esteira a construção de formas específicas de subjetividade. Para ilustrar a discussão, analisamos dois anúncios virais de uma consultoria de investimentos veiculados no YouTube que encenam a nova ordem político-econômica de forma problemática e geradora de resistências.
RESOLUÇÃO DE PROBLEMAS E CONSTRUÇÃO CONJUNTA DE CONHECIMENTO NA FALA-EM-INTERAÇÃO EM CENÁRIO DE DESENVOLVIMENTO TECNOLÓGICO
Authors: Kanitz Andréia , Garcez Pedro
Published: September 2020

RESUMO Com vistas à qualificação do que sejam momentos de construção conjunta de conhecimento, descrevemos situadamente aqui a atividade interacional de resolução de problemas em cenário de desenvolvimento de tecnologia de ponta, onde, em contraste com as salas de aula, não há quem detenha de antemão os conhecimentos requisitados. Examinamos um segmento de resolução de problema, representativo do conjunto de instâncias identificadas em corpus de 60 horas de gravações audiovisuais geradas em laboratório de tecnologia voltado à produção de materiais biomédicos. A atividade de resolução de problema é descrita enquanto instância interacional em que há um obstáculo a ser transposto por todos os participantes envolvidos na interação. Diante dos problemas e da necessidade iminente de resolvê-los, os participantes engajam-se no trabalho de construção conjunta de conhecimento, sendo essa construção observável nas ações que os próprios participantes realizam para os fins práticos de retomada das atividades que vinham realizando. Esse exame situado de experiência vivida de produção conjunta de conhecimento pode servir de referência para projetos de trabalho e aprendizagem em pedagogias ativas.
A LITERATURA DE TONI MORRISON NO BRASIL: BELOVED E SUAS PARATRADUÇÕES
Authors: Silva Luciana de Mesquita
Published: September 2020

RESUMO Este artigo tem como objetivo abordar as traduções do romance Beloved (1987), de Toni Morrison, no Brasil, com foco em alguns de seus paratextos. Inicia-se com uma reflexão teórica sobre tradução que a considera como um processo que ultrapassa a transposição linguística entre o texto-fonte e o texto-meta, uma vez que envolve fatores sociais, históricos, culturais, ideológicos, entre outros. Em seguida, apresenta-se a teoria da paratradução, segundo a qual os paratextos que compõem uma obra traduzida são importantes elementos a serem examinados pelo pesquisador, já que contribuem para a construção de sentidos. Posteriormente, o artigo traz um breve panorama sobre Toni Morrison e sua produção literária, destacando Beloved, e prossegue com uma análise das capas e contracapas das diferentes edições de Amada, título da referida obra no Brasil. Por fim, verifica-se que, em geral, as paratraduções brasileiras de Beloved reforçam as imagens de Morrison como escritora premiada e do romance em questão como um livro aclamado pela crítica.
TRADUÇÃO E PARATRADUÇÃO DO ROMANCE CLOUD ATLAS (2004) DE DAVID MITCHELL NO BRASIL
Authors: Caribé Yuri Jivago Amorim
Published: September 2020

RESUMO Esta pesquisa traz reflexões sobre paratextos relacionados ao romance inglês Cloud Atlas (2004), de David Mitchell e o processo de paratradução dessa obra, publicada no Brasil como Atlas de Nuvens (2016). O lançamento da tradução desse romance foi amplamente divulgado por importantes canais de comunicação, com apoio especial da crítica literária especializada. No entanto, a obra ainda é pouco lida e analisada no âmbito acadêmico. Assim, trabalhamos especialmente com o conceito de paratradução de Yuste Frías (2014 e 2015) para verificar o papel desempenhado pelos paratextos na edição final dessa obra traduzida. As conclusões apontam para um repensar do processo tradutório, diretamente influenciado pelo conceito de paratradução. Também nos levam a refletir sobre a participação dos paratextos como importante elemento de análise no processo de tradução literária de uma obra.
DISCURSO POPULISTA EM CONSTRUÇÕES JORNALÍSTICAS ACERCA DO CACEROLAZO ARGENTINO E DO PANELAÇO BRASILEIRO
Authors: Andrade Antonio , Marinho Priscila da Silva
Published: September 2020

RESUMO Este artigo debate a relação entre jornalismo, populismo e mídias digitais. Deste modo, observamos de que maneira os textos jornalísticos, ao produzirem narrativas acerca das manifestações sociopolíticas conhecidas como “cacerolazo”, em 2012/2013 na Argentina, durante o governo de Cristina Kirchner, e “panelaço”, em 2015 no Brasil, durante o governo de Dilma Rousseff, reforçam o processo de propagação de elementos discursivos que se imiscuem à lógica do populismo e se imbricam às dicções populistas do contemporâneo, que vêm sendo denominadas como populismo algorítmico e/ou populismo digital. Ao promoverem a circulação de certos dizeres (e não outros), partindo do efeito discursivo de evidência, como se fossem apenas “relatos de fatos”, baseados na ilusão de neutralidade e imparcialidade, as construções jornalísticas produzem uma determinação dos sentidos, filiando-se a dadas práticas discursivas, sócio-historicamente marcadas. A atividade jornalística, ao se apropriar do discurso populista, contribui para a instalação no cenário político de polaridades e dicotomias que resultaram, no contexto argentino, na derrocada do kirchnerismo em 2015 e, no contexto brasileiro, no impeachment da presidenta Dilma Rousseff em 2016. A fim de ilustrarmos nossa discussão, analisaremos, a partir da perspectiva teórico-metodológica da Análise do Discurso, algumas manchetes, trechos de reportagens e fotografias, disponibilizados nos sites dos jornais argentinos Clarín e La Nación e nos jornais brasileiros Folha de S. Paulo e O Globo, na época dos eventos mencionados.
O MOVIMENTO DE REPRODUÇÃO SOCIAL E RESISTÊNCIA NA CONSTRUÇÃO IDENTITÁRIA DE UMA PESSOA TRANS NUMA ATIVIDADE DE LÍNGUA INGLESA À LUZ DOS CONCEITOS DE INDEXICALIDADE E ESCALA
Authors: Lima Neto Luiz Martins de
Published: September 2020

RESUMO Neste artigo, rediscuto, à luz dos conceitos de indexicalidade e escala, o movimento de reprodução social e resistência numa atividade de língua inglesa, na qual as/os alunas/os de um curso de inglês e eu, professor da turma, construímos a identidade de uma pessoa trans (BENTO, 2014). Tal movimento foi primeiramente discutido na minha dissertação de Mestrado (LIMA-NETO, 2017). A rediscussão do material empírico neste texto mostra que os conceitos utilizados contribuem para a compreensão de como as ideias e os comportamentos hegemônicos são reproduzidos e resistidos interacionalmente, principalmente, porque nos permitem relacionar o micro ao macro, e vice-versa, mostrando-nos, assim, como esses dois níveis escalares se constituem, de fato, mútua e indexicalmente.
POR UM PARADIGMA TRANSPERIFÉRICO: UMA AGENDA PARA PESQUISAS SOCIALMENTE ENGAJADAS
Authors: Windle Joel , Souza Ana Lúcia Silva , Silva Daniel do Nascimento e , Zaidan Junia Mattos , Maia Junot de Oliveira , Muniz Kassandra , Lorenso Silvia
Published: September 2020

RESUMO Este texto propõe uma agenda de pesquisa sobre a produção de espaços de diálogo e solidariedade entre territórios periféricos. O termo ‘transperiferias’ traduz esta proposta de pesquisa e engajamento, elaborada coletivamente por sete pesquisadores/as situados/as no campo aplicado dos estudos da linguagem. A agenda das transperiferias oferece caminhos de ruptura com paradigmas que situam, de um lado, a produção de conhecimento sobre desigualdade e, de outro lado, os sujeitos e territórios que se engajam com a contestação dessa desigualdade a partir de posicionalidades marginais. Propõe-se, em outras palavras, uma aproximação entre a produção de saber “sobre” as periferias com a produção de conhecimento “das” periferias, ao mesmo tempo em que se projetam espaços de diálogo e reflexão “entre” periferias, regionais, nacionais e globais. O texto justapõe os tipos de engajamento e produção epistêmica de cada um/a dos/as pesquisadores/as, de modo a apontar para formas em que objetos de investigação, como letramentos, tradução, processos de racialização, enregistramento sociolinguístico, violência etc., podem ser revisitados numa visão transperiférica. Convidamos sujeitos de diferentes periferias, bem como campos epistêmicos diversos, a ampliarem e tensionarem essa agenda de investigação.
