Effect of gamma radiation and pasteurization on the shelf-life of juçara pulp (Euterpe edulis)
Authors: Silva Paula Porrelli Moreira da , Martin José Guilherme Prado , Spoto Marta Helena Fillet
Published: April 2019

Several studies about juçara palm fruit (Euterpe edulis) have emphasized its high antioxidant capacity.  However, there is a lack of studies comparing the effects of conservation technologies on the physicochemical and sensory quality of juçara pulp.  This work aimed at evaluating the effects of gamma radiation (60Co) and pasteurization process on the physicochemical and sensory quality of juçara pulp.  The irradiated (2.5 ± 0.06 kGy) and pasteurized (80°C/5 minutes) pulps were stored at 6°C, 90% RH, for 30 days (3 periods of analysis) and were analyzed for their microbiological, physicochemical (titratable acidity, soluble solids content, color, phenolic compounds, anthocyanin content, polyphenol oxidase and peroxidase activity) and sensory parameters (acceptance test.  The physicochemical results were submitted to ANOVA for the ‘F’ test and the statistical difference of averages (P < 0.05) was determined by the Tukey’s test.  The results of the sensory analysis were submitted to Principal Component and Cluster Analysis.  The gamma radiation did not show satisfactory results in the preservation of juçara pulp since there was a significant decrease in total phenolics and anthocyanin content.  The pasteurized pulp maintained its physicochemical and sensory characteristics during storage.  Therefore, we recommend the pasteurization as a good conservation technique to this kind of product, which presented a shelf-life of around 15 days

Reinforcement Learning: Connections, Surprises, Challenges
Authors: Barto Andrew G.
Published: April 2019

The idea of implementing reinforcement learning in a computer was one of the earliest ideas about the possibility of AI, but reinforcement learning remained on the margin of AI until relatively recently. Today we see reinforcement learning playing essential roles in some of the most impressive AI applications. This article presents observations from the author's personal experience with reinforcement learning over the most recent 40 years of its history in AI, focusing on striking connections that emerged between largely separate disciplines and on some of the findings that surprised him along the way. These connections and surprises place reinforcement learning in a historical context, and they help explain the success it is finding in modern AI. The article concludes by discussing some of the challenges that need to be faced as reinforcement learning moves out into real world.
Multifunctional cement composites with expanded graphite for temperature monitoring of buildings
Authors: Pichór Waldemar , Frąc Maksymilian
Published: April 2019

The results of research on cement composites with expanded graphite for application in temperature monitoring are presented. Two series of cement mortars were prepared with expanded graphite obtained from intercalated graphite by rapid heating at 500°C and 1000°C. The relation between temperature and electrical resistivity and the thermoelectric properties of the mortars with expanded graphite were investigated. Based on the measurements, the temperature coefficient of resistivity and the Seebeck coefficient were determined. The change in resistivity with temperature in heating–cooling cycles and the change in thermoelectric voltage for temperature gradient cycling were studied. Furthermore, the long-term resistance and thermoelectric voltage of mortars exposed to atmospheric conditions were measured. The results indicate that cement composites with expanded graphite exhibit very promising properties for temperature monitoring. It was found the composites containing expanded graphite obtained at 500°C were better for temperature monitoring by means of the Seebeck effect, whereas composites with expanded graphite obtained at 1000°C were suitable for temperature monitoring by means of resistivity change. Moreover, the results revealed that the percolation threshold of expanded graphite should be exceeded in the cement matrix in order to apply these composites in temperature monitoring by means of change of resistivity.

Published: April 2019

Dental pulp repair is a difficult clinical problem. In the present study, the authors aimed to mimic the extracellular matrix of dental pulp tissue structurally and compositionally. Nanofibrous silk fibroin (SF) scaffolds containing hydroxyapatite (HAp) nanoparticles were fabricated by using the freeze-drying approach. Rod-shaped HAp was successfully embedded in the composite scaffold, the diameter of which was about 100–200 nm as shown by transmission electron microscopy analysis. The three-dimensional microstructure of the composite scaffold prepared in various ratios of HAp to SF was observed by scanning electron microscopy and the pore size of the optimal scaffold was about 30–120 μm. Meanwhile, the hemocompatibility of the composite scaffolds was evaluated based on their impact on the clotting function by way of activated partial thromboplastin time, prothrombin time and thromboelastographic assays. The scaffolds possessed a low hemolysis rate of red blood cells. Furthermore, cell culture tests using dental pulp stem cells found that the scaffolds had good biocompatibility. There biomimetic HAp/SF composite scaffolds may serve as a promising biomaterial for dental pulp repair.
Groundwater level under vacuum consolidation
Authors: Chai Jinchun , Lu Yitian , Fu Hongtao
Published: April 2019

This study investigates the reduction of groundwater level in the soil deposit below the ground surface under vacuum consolidation. Theoretically, when the applied vacuum pressure is less than the air-entry value (AEV) of the soil deposit, the deposit will be in a saturated state and the groundwater level in the pre-fabricated vertical drains (PVDs) will not go below the ground surface during the vacuum consolidation process. In this case, the groundwater level is not a phreatic water level. If the applied vacuum pressure is larger than the AEV of the soil, part of the soil deposit can become unsaturated and the groundwater level in the PVDs can go below the ground surface. Further, the results of a large-scale vacuum consolidation model test using clay confirmed that during the consolidation process, the water level in the mini-PVD was always above the top surface of the model ground. Therefore, an attempt to measure the groundwater level in a vacuum consolidation area composed of clay deposits may not be worthwhile.

Published: April 2019

Assessments of wave energy resources form the basis of plans for developing and using wave energy, and provide guidance about where to site wave power stations and how to design wave energy convertors. Various indexes, including the spatial and temporal distributions of wave energy fluxes, the occurrence of the effective significant wave height, monthly and seasonal variability and the frequency of high sea states, were calculated from the recent 37-year European Centre for Medium-Range Weather Forecasts ERA-Interim reanalysis of wave field data. The results showed that areas with abundant and stable exploitable wave energy in the South China Sea were mainly between the Luzon Strait and the southeast of the Indo-China Peninsula, where the annual average wave energy fluxes ranged from 10 to 18 kW/m and the monthly and seasonal variability indexes were less than 2·2 and 1·6, respectively. The wave energy was found to be poor in some coastal areas of the Beibu Gulf, the Gulf of Thailand and the Sulu Sea. In the areas where wave energy was abundant, high sea states occurred frequently, meaning that it was relatively difficult to use the energy. Therefore, the wave energy resources and the frequency of high sea states need to be considered when choosing sites for wave energy farms.

Authors: Dobrina M V , Davnis V V , Belokopytova T N
Published: April 2019

Цель: обоснование необходимости применения эконометрических моделей с дискретной зависимой переменной для моделирования инвестиционных решений на фондовом рынке. Обсуждение: применение Шарпом однофакторных регрессионных моделей в портфельном анализе позволило обновить теорию портфельного инвестирования новыми результатами. Было получено представление о структурировании риска и введено понятие портфельной беты. В настоящее время аппарат эконометрического моделирования пополнился новыми моделями, в которых зависимая переменная является дискретной. Во многих случаях динамику доходности финансовых активов удобно представлять в виде дискретных временных рядов. В силу этого возникает идея применения этих новых моделей в задачах портфельного инвестирования. Результаты: рассмотрена возможность применения эконометрической модели бинарного выбора для моделирования доходности рыночного актива. На основе этой модели были получены формулы для расчета доходности и дисперсии актива, которые можно использовать при построении оптимального портфеля ценных бумаг.

Цель: выявление и систематизация как факторов, определяющих параметры трудового потенциала, так и факторов, способствующих его эффективной реализации. Обсуждение: актуальность темы исследования вызвана все возрастающим значением трудового потенциала для развития любых экономических систем. Авторы исследуют методические подходы к количественной оценке трудового потенциала с учетом его качественной составляющей. Также они уделяют существенное внимание тем условиям, которые делают возможной и желательной реализацию этого потенциала в рамках экономической системы. Результаты: предлагается проводить оценку трудового потенциала по четырем направлениям: доступный объем труда, интегральная оценка качественных составляющих трудового потенциала, экономические и инфраструктурные возможности для его реализации, стимулы к такой реализации. Учет факторов этих четырех групп представляется наиболее приближенным к объективной и комплексной оценке не только размера и качества имеющегося трудового потенциала, но и его возможного влияния на состояние экономической системы в целом.
НОВАЯ ХОЗЯЙСТВЕННАЯ СИСТЕМА ДЛЯ ГОСУДАРСТВЕННЫХ ПРЕДПРИЯТИЙ В РАЗВИВАЮЩИХСЯ СТРАНАХ
Authors: Imanov R A , Zhivitsa V I , Ponomareva O S , Fursov V I
Published: April 2019

Цель: рассмотреть для государственных предприятий новую модель хозяйствования, теоретическим фундаментом для которой выступают три закона диалектики и Гегелевская триада развития. Обсуждение: показано, что хозяйственная система должна разрабатываться на основе модели хозяйствования соответствующих элементарных экономических клеток (ЭЭК), из которых состоит данное общество. При этом методология ценообразования, которая сложилась в условиях частной собственности, не меняется при переходе к новой общественно-экономической формации, применяющей распределение по труду. Объяснятся это тем, что при смене общественно- экономических формаций появляется новая ЭЭК общества. Результаты: модель хозяйствования новой ЭЭК общества переворачивается по сравнению с моделью хозяйствования ЭЭК сменяемого общества. При этом модель хозяйствования новой ЭЭК общества становится подобной модели хозяйствования ЭЭК клетки того общества, которое существовало до сменяемого общества. Таковы законы диалектики.

Published: April 2019

Цель: методическое обоснование построения комбинированной модели, обеспечивающей возможность многомерных прогнозных расчетов с учетом системной сбалансированности динамики социально- экономического развития. Обсуждение: многомерность – одна из основных проблем, которую нужно преодолеть при прогнозировании социально-экономического развития. В то же время в рыночной экономике подход, на основе которого происходит построение прогноза таких систем, опирается в большей степени на методы экспертных оценок. Поскольку данные, описывающие вектор развития таких систем, представлены в цифровом формате, предполагаемый подход должен включать в себя формализованные методы. Одним из возможных подходов для решения данной проблемы является модель на основе матричного предиктора, в которой эконометрический подход будет соединяться с идеями многомерного прогнозирования, позволяя осуществить системно-сбалансированный прогноз динамики. Результаты: подробно изложены методические основы процедуры построения комбинированной модели на основе матричного предиктора с учетом системной сбалансированности динамики.

Após três meses de tratamento, os ratos diabéticos tratados com R. sativus tiveram uma marcante diminuição na glicemia de jejum, comparados aos ratos diabéticos não tratados (p < 0,05). Além disso, este tratamento preveniu tanto a oxidação proteica no fígado como o aumento dos níveis de triglicérides sérico (p < 0,05). Portanto, demonstrou-se um marcante efeito anti-hiperglicêmico de R. sativus (a uma baixa dose) e as extensivas ações em prevenir típicas complicações do DM, tais como os danos oxidativos e dislipidemia, demonstrando que esta planta apresenta um potencial terapêutico.
Problems of formation of an international regime of the joint use and protection of international watercourses
Authors: Sluchevskaya Yu. A.
Published: April 2019

The article is devoted to the problem of formation of modern international legal regime of joint use and protection of international watercourses that is aimed at effective provision of water to the States of international watercourse with due respect to new challenges and threats that have a negative impact on international water resources. The model is based on the concept of “international watercourse” that has the following features: 1) international watercourses include surface and ground waters; 2) a spatial and territorial criterion of an international watercourse that means crossing of the border between two or more States or being on their border; 3) the use of international watercourses affects the interests of two or more States; 4) the special international legal regime for the use of international watercourses that has developed within the framework of international law development; 5) special requirements for the protection of ecosystems of international watercourses that include protection from pollution and other forms of degradation of lands and forests adjacent to international watercourses, their fauna and flora; as well as seas into which watercourses flow; 6) a high conflict potential in the use of water resources of international watercourses. The analysis of the provisions of the doctrines of joint use and protection of transboundary waters shows that the formation of international water law should timely take into account human factors, technological and socio-economic changes. The modern international law model of the joint use and protection of international watercourses is a system of international legal norms regulating inter-state relations in the following areas: prevention, limitation and reduction of transboundary impact; protection of ecosystems of international watercourses; rational use of waters of international watercourses, effective management of water resources of international watercourses (including establishment and functioning of international basin organizations); information support of the population with regard to international watercourses.
Current state and prospects of development of a civil suit in criminal proceedings
Authors: Sushina T. E.
Published: April 2019

The paper analyzes the current state and prospects of development of the mechanism of compensation of harm in criminal proceedings. It is noted that with a steady trend of growing discontent of the majority of victims with the state’s activities to restore their rights violated because of the crime, the courts properly resolve civil claims in criminal cases. The reasons why article 52 of the Constitution of the Russian Federation remains declarative are revealed. The conclusion about the inadmissibility of expanding the subject and grounds of civil claims in criminal proceedings is substantiated. It is indicated that the foreign practice of compensation for harm to victims, including through the formation of compensation funds, the use of mediation procedures, funds of non-governmental organizations, faces many problems that remain unresolved. In this regard, it is proposed to use only the institutions of restitution and voluntary compensation of harm in the criminal process, actively using the possibilities of pre-trial stages, as well as to consider claims that clearly arise from the substance of the criminal law dispute and (or) recognized by civil defendants. The remaining civil law issues directly or indirectly related to the committed or impending crime should be resolved in civil proceedings, where the burden of proof of the asserted claims is placed on the person recognized as the victim in the criminal case, his heir or representative. An important role is given to the improvement of the system of execution of court decisions, including through the development of programs based on the achievements of modern digital technologies.

Authors: Nikityuk Igor E. , Kononova Elizaveta L. , Baskov Vladimir E. , Imomov Khisrav D.
Published: April 2019

Background. Deforming arthrosis of the hip joint in children leads to serious disorders of the walking biomechanics due to a decrease in the support and motor functions of the lower limbs. In patients with stage III coxarthrosis, when the potential of reconstructive surgeries has been exhausted, a total hip arthroplasty is performed.
Objective. To study the biomechanical parameters of support ability of the lower limbs in children with bilateral coxarthrosis before and after bilateral total hip arthroplasty.
Material and methods. Stabilometric and plantographic studies were conducted in 12 patients with bilateral coxarthrosis, aged from 13 to 17 years old, before and after hip arthroplasty. The time interval between operations on the contralateral joints ranged from 6 to 12 months. The control group consisted of 15 children of the same age, with no signs of orthopedic disorders.
Results. Before carrying out hip arthroplasty in patients, the tension of the statokinetic system was revealed during the implementation of support for the vertical balance of the body. The plantography method made it possible to diagnose disorders of the support function of the feet in the form of supination rigidity of the anterior section, a tendency toward rigidity of the internal longitudinal arch. After bilateral total hip arthroplasty in patients, the stability of the vertical posture improved, the support ability of the heads of the 1st metatarsal bones was significantly restored, and the weight-bearing distribution across the foot sections was normalized.
Conclusion. After bilateral hip arthroplasty in patients with coxarthrosis, stabilization of the support function of the postoperative lower limbs was achieved.

Background. Childhood solid tumor survivors are known to be at risk for serious musculoskeletal late effects that may result in disability, associated with multicomponent antitumor treatment.
Aims. To improve the quality of life of childhood bone sarcoma survivors.
Materials and methods. Forty-six children and adolescents (22 males, 24 females) were treated for primary bone sarcomas (follow-up, 22216 months). Mean age at orthopedic diagnosis was 15.09 years (range, 623 years). Treatment consisted of neoadjuvant chemotherapy and radiotherapy of the initial tumor and metastasis left after induction and/or oncologic surgery and adjuvant chemotherapy. We used the NCI Common Terminology Criteria for Adverse Events for reporting.
Results. The most common grade of late effects observed was grade 2 (91 cases). We observed serious adverse events, that is, grade 4 (life-threatening consequences) in five cases and grade 5 (death related to adverse events) in one. A total of 32 orthopedic patients had fewer than six late effects, while 14 had more than six late effects.
Conclusions. The development of musculoskeletal sequelae is unavoidable in the majority of the survivors due to the need to use them in very aggressive treatment strategies leading to a significant increase in survival. Early diagnosis and orthopedic correction of adverse effects are necessary to ensure an acceptable quality of life and good social adaptation of patients.

Published: April 2019

Flavonoid-mediated materials are promising substances for the design of new functional materials because of their bioactivity, eco-friendliness, and cost-effectiveness. Dihydroquercetin (DHQ) is the major flavonoid in the wood of Larix dahurica Turcz. Previously some new modifications were created on the basis of DHQ, they were characterized by different morphological, physico-chemical and biopharmaceutical properties. This study was performed to research the influence of the solvent on the formation of the solid phase in DHQ microtubes and crystal form as commercially available active pharmaceutical ingredient (API). The choice of the models for the computational simulation was based on the data of differential scanning calorimetry. All calculations were performed using Materials Science Suite. In silico analysis demonstrated that the molecules of solvent are a key player in the formation of the solid phase of the flavonoid-mediated material. Also the comparative analysis of physical characteristics between DHQ microtubes and crystal form was performed. These data give an opportunity to suggest, that DHQ microtubes may have a grate application as the dressing material and in the drug delivering. The results of this study could be helpful for the design of the new flavonoid-mediated materials by crystal engineering.

Results: 82% patients were of age less than 30 years. The overall male: female ratio was 1.3:1. In Group 1, 76% had gain of 15 db while 12% had gain of >15 db. In Group 2, 72% had gain of 15 db and 8% had gain of >15 db. The graft was intact in 84% patients. 12% of Group 1 patients, showed residual perforation whereas it was 20% in Group 2 patients.

Conclusions: The study showed that: the temporalis fascia graft is better than conchal perichondrial graft for closure of perforations in inactive mucosal type of chronic otitis media with central perforation because of maximum hearing improvement and minimal failure rate in group receiving temporalis fascia graft.

O papel e a trajetória da Pesquisa Científica na formação de professores de Matemática: um Estudo de uma licenciatura
Authors: BITENCOURT LORIÉGE PESSOA , Moura Liliana Karla Jorge de
Published: April 2019

Neste artigo apresentam-se algumas reflexões a partir de práticas docentes em duas disciplinas curriculares: Pesquisa em Educação Matemática (PEM) e TCC I, respectivamente, no 5° e 6° semestres da formação inicial do professor de Matemática, desenvolvida em uma universidade pública do estado de Mato Grosso. Discute-se sobre a importância e o papel da pesquisa científica na formação inicial em Matemática, com a perspectiva de evidenciar, na trajetória desse componente curricular, os pontos positivos desse processo formativo de pesquisa e os resultados encontrados até o momento. Aborda-se também o modo com que o processo formativo de pesquisa se materializa na matriz curricular da licenciatura em pauta e na prática dos sujeitos envolvidos nesse processo: docentes e discentes. O artigo tem como objetivo articular discussões sobre pesquisa científica na formação de professores de Matemática, currículo (Processo formativo) e docência universitária, em interação com os discentes no processo formativo. Os dados foram coletados durante dois semestres letivos, 2015/2 e 2016/1, por meio de reflexões realizadas nas disciplinas visadas. O estudo, de abordagem qualitativa e caráter descritivo analítico, envolveu a participação direta dos pesquisadores no ambiente investigado. Para subsidiar a análise foi realizado um levantamento bibliográfico, com enfoque na investigação científica e na análise documental, visando verificar, em documentos, as diretrizes, internas e externas para o processo formativo da pesquisa nas licenciaturas. Parte dos resultados e discussões possibilitou traçar o perfil dos estudantes das duas disciplinas,  explanando o processo de pesquisa em ambas. Assim, ficou explícito, na análise, que a estrutura curricular proposta em 2012 permite que o aluno vivencie o processo de forma contínua, proporcionando melhor aprofundamento do tema, e também  um trabalho conjunto e colaborativo mediante acompanhamento do professor orientador.
A pedagogia da alternância como possibilidade formativa nas licenciaturas em educação do campo
Authors: Sartori Jerônimo , Da Silva Denilson , Pagliarin Lidiane Limana Puiati
Published: April 2019

Este estudo teve como objetivo analisar a pedagogia da alternância como constitutiva da formação de professores para atuar na educação do/no campo. O debate está ancorado em autores como Freire (1996), Arroyo (2012), Caldart (2004; 2012), Molina (2011; 2015), dentre outros. A pesquisa é de natureza qualitativa, com utilização de questionários aplicados para alunos do curso Interdisciplinar em Educação do Campo: Ciências da Natureza (Licenciatura), curso que possui sua organização curricular constituída por tempos e espaços alternados de formação, entre a universidade e a comunidade onde residem os acadêmicos. Tal coleta de dados foi realizada em duas etapas, sendo a primeira com questionário online composto de questões fechadas que envolveram aspectos da organização curricular no processo formativo no Curso. Na segunda coleta – para aprofundar algumas questões suscitadas na primeira – realizou-se um questionário com perguntas abertas sobre temas estruturantes da formação de professores como: interdisciplinaridade, ensino de Ciências da Natureza, formação de educadores à Educação do Campo e Pedagogia da Alternância. O estudo realizado é fruto da análise das respostas de ambos os questionários sobre a Pedagogia da Alternância como possibilidade formativa no Curso. Mediante análise dos dados coletados podemos afirmar que a Pedagogia da Alternância apresenta muitas possibilidades formativas, dentre elas, o auxílio na articulação de saberes acadêmico-científicos com aqueles da origem da prática social dos acadêmicos em formação. Por sua vez, esta modalidade de organização curricular também evidencia diversos desafios, principalmente para os formadores que atuam em cursos com esta modalidade de oferta - Pedagogia da Alternância. Nesse sentido, é preciso haver planejamento, acompanhamento e avaliação permanente dessas atividades, para que elas sejam formativas e que estejam de acordo com a realidade e demandas desses acadêmicos.
Diversidade étnico-racial e formação de professores no instituto federal de educação, ciência e tecnologia de Minas Gerais - campus Ouro Preto (IFMG/OP)
Authors: Silva Natalino Neves da
Published: April 2019

As reflexões aqui desenvolvidas resultam da realização de uma pesquisa inserida no Programa de Iniciação Científica que buscou entender como a diversidade étnico-racial é percebida pelos/as graduandos/as do Curso de Licenciatura de Geografia do Instituto Federal de Educação, Ciência e Tecnologia (IFMG) - Campus Ouro Preto. O estudo focalizou nos discentes os quais se encontravam nos último período do curso. Para a coleta de dados utilizamos da aplicação de um questionário. Fez parte ainda como procedimento metodológico de pesquisa o levantamento, o estudo e a análise dos principais documentos da legislação brasileira sobre o tema. Os resultados obtidos revelaram que uma parcela significativa de graduandos/as desconhece a Lei 10.639/03 as suas Diretrizes. E mais, eles(as) consideram que não se sentem preparados para trabalhar com os sujeitos em sua diversidade étnico-racial na escola. Nesse sentido, ponderamos sobre a necessidade de se trabalhar com a Educação das Relações Étnico-Raciais (ERER), conforme preconizada em Lei, na formação inicial de futuros docentes nos Institutos Federais de Educação, Ciência e Tecnologia (IFs).

Aim.The aim of this work is to summarize the available data on zoogeographic analysis and fauna of the bats of the Altai-Sayan region.

Discussion.The chiropterofauna of the AltaiSayan highlands includes the representatives of 13 species. The obtained data on the distribution of bats in the region made it possible for the first time to carry out a zoogeographic analysis of the chiropterofauna of the Altai-Sayan highland. The faunal complex of bats in the study area and adjacent territories is represented by boreal, European and Central Asian species. The cluster analysis by Jaccard coefficient allowed us to distinguish two main chiropterological complexes: Altai-Sayan and Ubsunur. Our boundary between these complexes coincides or is close to the biogeographic boundaries drawn for various groups of vertebrates and invertebrates, as well as plants.

Conclusion.Altai-Sayan territory is inhabited by 13 bat species of six genera belonging to Vespertilionidae family. The most common species are the following: eastern water bat –Myotis petaxHollister, 1912; Siberian bat –Myotis sibiricusKastschenko, 1905; Ikonnikov's bat –Myotis ikonnikovOgnev, 1912; Northern bat –Eptesicus nilssoniiKeyserling, Blasius, 1839; Parti-coloured bat –Vespertilio murinusLinnaeus, 1758; Ognev's long-eared bat –Plecotus ogneviKishida, 1927. In the fauna of the region, the boundary between two chiropterological complexes (Altai-Sayan and Ubsunur) runs through Kurtushibinsk-Usinsk province.

Las aventuras de Huckleberry Finn: una herramienta de la literatura para desarrollar las habilidades del inglés como lengua extranjera y para entender la cultura norteamericana del siglo XIX
Authors: Cárdenas Reyes Yeison Mauricio
Published: April 2019

This paper discusses and proposes a set of didactic approaches and proposals for teaching English as a foreign language and North American culture through Mark Twain’s Adventures of Huckleberry Finn to students from the Bachelor’s Degree in Foreign Languages. The paper addresses three main topics: 1) the didactic and discursive relevance of the text for their respective study in the classroom; 2) the instrumentalization of the book to understand the sociocultural context of the time; and 3) the reflection on how to didactically establish a pedagogical device to analyze two main themes of the book, such as religion and slavery
La carrera por la teoría
Authors: Christian Barbara
Published: April 2019

This paper is a translation of the chapter “The Race for Theory,” by Barbara Christian, which aims to highlight a corpus of barely studied African-American authors up to the 1990s, insisting on the power of their narratives, on the role of race, class and gender in their works and on a proper literary review of those works. Nowadays, it is relevant because it insists on consolidating a philosophy of literary review within the context of black feminism

Authors: Almeida Shirley Patrícia Nogueira de Castro e , Gomes Maria Laura Magalhães
Published: April 2019

Este artigo busca caracterizar a cultura acadêmica do curso de Matemática da Fundação Norte Mineira de Ensino Superior (FUNM), posteriormente Universidade Estadual de Montes Claros (Unimontes), no período 1960-1990. Com a análise de planos de ensino, diários de classe, livros-texto e entrevistas de antigos professores e alunos conduzidas na metodologia da História Oral, o estudo visou compreender as práticas pedagógicas realizadas e as concepções sobre o tipo de professor de Matemática que se pretendia formar. Quanto às práticas, destacaram-se a utilização da exposição oral, a organização do contexto da aula, a explicitação dos objetivos de ensino e o uso de exemplos e de exercícios. O professor formado deveria ser um bom transmissor e conhecedor da matéria, saber articular os conceitos trabalhados à vida cotidiana e a teoria à prática e localizar os conhecimentos histórica e socialmente.
