The ensemble algorithm for estimation of model parameters in the problem of assessing greenhouse gases fluxes
Authors: Klimova E.G.
Published: December 2021

The problem of assessing the greenhouse gases fluxes from the Earth’s surface based on observations is currently very urgent. To solve it, it is customary to use data assimilation systems (or a more general concept — inverse modeling), which include the observations on the concentration of greenhouse gases and models of the transport and diffusion. Since such problems involve large volumes of satellite data and the global model of transport and diffusion, it has a huge dimension. For this reason, the development of effective algorithms to enable the practical implementation of the task is required. The paper discusses data assimilation algorithms based on the ensemble Kalman filter and ensemble Kalman smoothing, which can be used to solve the problem of estimating greenhouse gases fluxes. Economical algorithms for estimating a parameter that is constant over a given time interval are proposed.

Published: December 2021

New simulation results, obtained from the chemical version of the regional climate model RegCMCHEM4, are presented for Siberian region. The verification of the chemical subsystem of the model with non-hydrostatic dynamical core is carried out using the atmospheric chemical transfer scheme CBMZ (Carbon Bond Mechanism-Z). To define chemical emissions the global RCP (Representative Concentration Pathways) emission dataset prepared by the International Institute for Applied Systems Analysis (IIASA), is used. For gas phase species, we have prepared the 6 hourly chemical boundary conditions from our modified version of the Model for Ozone and Related chemical Tracers, version 4 (MOZART-4). Quantitative estimates of methane emission in the atmosphere of the Siberian region have been obtained.

Authors: Kozik V.I. , Nezhevenko E.S.
Published: December 2021

A classification system for hyperspectral images using convolutional neural networks is described. A specific network was selected and analyzed. The network parameters, ensured the maximum classification accuracy: dimension of the input layer, number of the layers, size of the fragments into which the classified image is divided, number of learning epochs, are experimentally determined. High percentages of correct classification were obtained with a large-format hyperspectral image, and some of the classes into which the image is divided are very close to each other and, accordingly, are difficult to distinguish by hyperspectra.

Authors: Shvetsov E.G. , Tchebakova N.M. , Parfenova E.I.
Published: December 2021

In recent decades, remote sensing methods have often been used to estimate population density, especially using data on nighttime illumination. Information about the spatial distribution of the population is important for understanding the dynamics of cities and analyzing various socio-economic, environmental and political factors. In this work, we have formed layers of the nighttime light index, surface temperature and vegetation index according to the SNPP/VIIRS satellite system for the territory of the central and southern regions of the Krasnoyarsk krai. Using these data, we have calculated VTLPI (vegetation temperature light population index) for the year 2013. The obtained values of the VTLPI calculated for a number of settlements of the Krasnoyarsk krai were compared with the results of the population census conducted in 2010. In total, we used census data for 40 settlements. Analysis of the data showed that the relationship between the value of the VTLPI index and the population density in the Krasnoyarsk krai can be adequately fitted (R 2 = 0.65) using a linear function. In this case, the value of the root-meansquare error was 345, and the relative error was 0.09. Using the obtained model equation and the spatial distribution of the VTLPI index using GIS tools, the distribution of the population over the study area was estimated with a spatial resolution of 500 meters. According to the obtained model and the VTLPI index, the average urban population density in the study area exceeded 500 people/km2 . Comparison of the obtained data on the total population in the study area showed that the estimate based on the VTLPI index is about 21% higher than the actual census data.

Authors: Kirsta Yu.B. , Puzanov A.V. , Rozhdestvenskaya T.A. , Peleneva M.P.
Published: December 2021

Using the system approach, we have developed a simulation model for the long-term forecast of the content of toxic chemical elements in grain crop yield. The study was carried out by the example of wheat cultivated in Altai Krai — one of the main grain-producing regions of Russia. Wheat crops were sampled in 10 municipal districts of Altai Krai, which characterize seven different edaphic-climatic zones. The average long-term values of mean monthly air temperature and monthly precipitation for each sampling area were identified using GIS and data of the Interactive Agricultural Ecological Atlas of Russia and Neighboring Countries. A total of 19 chemical elements were considered, i.e. Pb, As, Cd, Hg, Na, Mn, Zn, Cu, Fe, Co, etc. It is shown that content of Pb, Na, Mn and Cu in wheat depend on climatic characteristics of the cultivation area. Regression dependences of element content on the average long-term air temperature and precipitation were established. Based on normalization and spatial generalization of air temperature and precipitation providing the uniform dynamics of their relative monthly values (in percent) throughout the study area, a forecast of their changes was made for 2030. A procedure for grain sampling, GIS technologies for processing meteorological and cartographic data, methods for predicting regional climate changes and establishment of quantitative relationships of chemical elements content in grain with climatic characteristics – all together make up the integral predictive simulation model for toxic substance content in grain crop yield. The model was used for estimation of Pb, Na, Mn, Cu changes in wheat by 2030. The lead (Pb) content in wheat crop delivered to elevators from certain municipal districts will exceed the maximum allowable concentration for breadgrain after 2030. Unlike Pb, Na, Mn, Cu, the content of other metals in wheat grain weakly correlate with long-term changes in air temperature and precipitation; therefore, it can hardly change significantly.

Authors: Eremenko V.S. , Naumova V.V.
Published: December 2021

Analysis of diverse data in geosciences requires access to various processing tools, including specialized software packages, proprietary algorithms, GIS systems, web services, etc. Such tools require from the user a certain level of skills to work with them, form a software environment, the availability of the necessary computing power, and sometimes significant time and financial costs. With the development of information technology, more and more software products, including professional software packages for data processing, are provided to users in the format of various cloud services and platforms. In such systems, computation takes place on the side of the service provider and is accessed through a web browser. The emergence of such open-access services and platforms makes it possible to organize a single workspace for a researcher with the ability to analyze his own data using various processing methods, including tools traditionally used in earth sciences. The report is devoted to the development of an approach for the integration of various tools for processing heterogeneous data with open access within a single multi-platform ecosystem. The software system developed based on the proposed approach is demonstrated. The report describes software modules that implement the functions of access to processing and analysis tools, as well as service modules for system administration, component monitoring and event logging. Services and processing platforms integrated into the ecosystem are considered, as well as scenarios for solving some geological problems.

Reaction of Sulfur and Sustainable Algae Oil for Polymer Synthesis and Enrichment of Saturated Triglycerides
Authors: Gupta Adarsha , Worthington Max , Puri Munish , Chalker Justin
Published: December 2021

There is growing interest in the bio-based production of lipids from algae. These lipids have a range of uses including nutritional supplements and precursors to biodiesel. Single-cell thraustochytrids are especially attractive in this regard in that they can produce over 50% of their weight as triglycerides. Furthermore, the distribution of saturated and unsaturated triglycerides can be modulated by changes in strain variation and modulation of fermentation conditions. Nonetheless, there remains a need for versatile downstream processing to enrich these so-called “single cell oils” into classes based on degree of unsaturation. In this study, we report a novel strategy for enriching saturated triglycerides produced in thraustochytrids. The method features direct reaction of elemental sulfur with the algae oil extract. The sulfur copolymerizes with >90% of the unsaturated triglycerides, providing a new route to a class of materials previously used in environmental remediation, Li-S battery cathodes, slow-release fertilisers, and insulation. The unreacted oil is enriched in saturated triglycerides, which can be isolated by extraction for potential use in biodiesel production. In this way, a single batch of sustainably produced algae oil can be converted into multiple useful products in a single step.

¿Toda actividad económica debe estar regulada?
Authors: Gómez Apac Hugo
Published: December 2021

El presente ensayo reconoce la importancia de la regulación para evitar o minimizar que una actividad económica genere daños o externalidades negativas. Sin embargo, explica que instrumentos de manejo regulatorio como el régimen de eliminación de barreras burocráticas y el análisis de impacto regulatorio sostienen como una posibilidad la ausencia de regulación, lo que no significa ausencia de estado. Así, un escenario posible que los hacedores de políticas públicas deben tener presente es que, si las circunstancias lo justifican, una determinada activida económica podría encontrarse exenta de regulación.

Los desafíos para que esta industria deje de ser solo una fuente de ingresos económicos para convertirse en generador de desarrollo son enormes, pero no imposibles. Es indispensable que los gobiernos trabajen en proteger y promover su desarrollo de un modo sostenible —y sin corrupción—, para eso la comunidad internacional coincide en que el camino es mejorar las instituciones públicas y fortalecer las relaciones y la confianza de los actores que gobiernan y/o interactúan en el sector. Este documento aborda dos planos de recomendación para ello: la transparencia efectiva de la información, y mejores y más transparentes empresas del Estado del Sector Extractivo.
Pop the “maths anxiety” bubble : an approach to support nursing students to self-manage anxiety while studying drug calculations
Authors:   Unitec Institute of Technology, Auckland, New Zealand, Dai Hua
Published: December 2021

This is a report on an informal action research undertaken between 2013 to 2014 to find solutions to support tertiary nursing students experiencing anxiety while studying drug calculation. The literature identifies traditional “Maths Anxiety” and modern-day specific categorisations of “Dyslexia” and “Dyscalculia”, yet offers no clear solution on how to support students. Exploring the constructive-developmental perspective of human development, the conception of the triune brain and the Psychosynthesis conceptual map of body-feelings-mind enabled me to develop an approach to base on all this wisdom in order to help students navigate their daily experience on campus and consciously express their will to succeed. These techniques proved to be successful, evidenced in the overwhelmingly positive feedback from both students and maths tutors. This article invites colleagues within the broader ATLAANZ community to adapt and apply this approach in their practice to support students with anxiety to succeed while studying.

Published: December 2021

Background: Enterobius vermicularis (pinworm) infestation is a common condition that primarily affects children. Aims: The aim of this study was to assess the prevalence of and the risk factors for E. vermicularis infestation in preschool children in north West Bank. Methods: A cross-sectional study that included the six main governorates in north West Bank was carried out on a sample of 384 preschool children from 86 day-care centres. The perianal cellophane tape method was used to detect E. vermicularis infestation. Parents/guardians of participating children completed a questionnaire to collect information about: demographic characteristics; hygiene behaviour; socioeconomic status; history of previous infestation; and presence of symptoms. Risk factors for infestation were assessed using logistic regression analysis. Results: Of the 384 children, 85 (22.1%) had E. vermicularis infestation. Age (P = 0.04), governorate (P = 0.01), residency (P = 0.03), number of household members (P < 0.001) and washing hands after toilet use (P = 0.01) were significantly associated with E. vermicularis infestation. In the logistic regression analysis, factors that increased the probability of infection were: living in villages (odds ratio (OR) 2.25; 95% confidence interval (CI): 1.01–5.00), living in a household with ≥ nine family members (OR 3.63; 95% CI: 1.42–9.26) and not washing hands after using the toilet (OR 2.4; 95% CI: 1.30–4.40). Conclusions: E. vermicularis is an important helminthic infestation among preschool children in Palestine. Efforts are needed to ensure the availability of treatment for infected children at primary care centres and to reinforce hygiene behaviour.
ECOLOGICAL AND ECONOMIC EFFICIENCY OF SUBSIDIZING THE USE OF FERTILIZERS IN AGRICULTURE OF KAZAKHSTAN
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, SEITOV S.K.
Published: December 2021

The article assesses the forms, mechanism, level, and dynamics of subsidizing fertilizers, using indicators and criteria to evaluate the results of the national implementation of the subsidizing policy. The work considers the efficiency of subsidies for the use of fertilizers, develops scientifically grounded recommendations for improving the system of subsidizing agriculture in Kazakhstan. The environmental component in agricultural subsidies should also be given immediate attention since the ecological situation in rural areas depends on it. In Kazakhstan, degradation of arable land occurs under the influence of mineral starvation and the unsystematic use of fertilizers. The current fertilizer subsidy mechanism does not encourage sustainable land use. The calculations using the developed formula show a low level of environmental and economic efficiency of subsidizing fertilizers in agriculture in Kazakhstan. In the republic, this level for grain was equal to 0.74. Based on the example of the research, the author shows that subsidies can be an effective means of soil conservation and a means of motivation for the use of environmentally efficient farming methods. For this purpose, the paper proposes re-orient subsidies in favor of farmers introducing differentiated fertilization methods.

Published: December 2021

The productivity potential of field crops is currently realized by no more than 25%. One of the main reasons is the deterioration of the phytosanitary situation due to low agricultural technology, the cultivation of unstable varieties, non-compliance with spatial isolation norms, and others. Rust diseases take the top place in the decline in the yield of most crops, especially cereals. In a stationary field three-factor experiment of the Department of Agronomy of Yaroslavl State Agricultural Academy, the authors studied the influence of resource-saving processing systems and fertilizers on the prevalence of rust diseases and the productivity of field crops. Over the years of research (2016–2019), stem rust of oats, yellow and brown rust of wheat, linear rust of timothy were found in the crops. In 2018, warm and humid weather favored increased development of oat stem rust in annual grasses. On average, in terms of factors, the use of the studied soil cultivation systems did not cause any significant changes in the prevalence of rust diseases on cereals with minimal values on the surface-moldboard soil cultivation system. The full rate of mineral fertilizers caused a statistically significant majority of leaf rust in 2017 by 4.58%. In 2018, the use of straw contributed to a significant increase in the prevalence of oat stem rust by 18.34%. On average, for the studied soil cultivation systems in 2019, the use of the full norm of mineral fertilizers, both separately and together with straw, led to a statistically significant decrease in the above indicator with the minimum values for the background “Straw+NPK” by 6.39%. The use of a surface treatment system for all the years of research has led to a slight decrease in the productivity of field crops in comparison with surface-moldboard treatment. On average, for soil cultivation systems, the use of all types of fertilizers increased the productivity of field crops with the maximum reliable values for the background “Straw+NPK.”

Seed productivity of perennial leguminous grasses is subject to sharp fluctuations due to their biological characteristics, different reactions to changes in growing conditions, and meteorological factors over the growing season. In this case, the productive longevity of herbs is of great importance. The research aims to analyze the seed productivity and the duration of using the grassstand of perennial legume grasses in the meteorological conditions of the Middle Pre-Urals. The analysis of seed yield, energy, and economic efficiency of long-term use of perennial leguminous grasses was carried out based on a result of studies laid down in the Udmurt Research Institute of Agriculture of the UdmFRC of the UB RAS in 1996–2005 with the eastern Galega variety Gale, in 2011–2015 – with varieties of red clover and variegated alfalfa, in 2011–2016 – with birds-foot trefoil variety Solnyshko. The research found that red clover sowing is best used for seeds for one year. In the first year of use, the yield of double-cut clover varieties was 146 kg/ha, of single-cut varieties – 138 kg/ha. In the second year of using the grass stand, the yield significantly decreased to 37 and 39 kg/ha. The yield of 162 kg/ha at the standard level was formed by the twocut clover variety Dymkovsky. Crops of variegated alfalfa can be used for seeds for two years. Seed productivity of variegated alfalfa varieties in the 1st year of use was 204 kg/ha, in the 2nd year of use – 260 kg/ha. Alfalfa of the Guzel variety formed a significantly high seed yield of 251 kg/ha. The recommended duration of the use of the birds-foot trefoil grass-stand is two to three years. In the 1st and 2nd years of use of the grass stand, the yield of the seeds was relatively high, 215–378 and 213–349 kg/ha, respectively. By the 3rd year of use, it decreased to 89–161 kg/ha. The old-age grass stand of the 4th year of use did not form seeds. Sowing the birds-foot trefoil without a cover or under cover of spring wheat by the usual row method with a seeding rate of 8–9 million units/ha showed the highest seed yield of 255–270 kg/ha. The duration of the use of the eastern Galega grass-stand is up to 10 years or more. The highest yield of Galega seeds of 510 kg/ha was obtained during the harvesting of grass in the first year of use for feed, in the second – fifth year of use – for seeds, from the 6th year of use – for feed.

Published: December 2021

The possibilities and feasibility of using the Bayesian network of trust and logistic regression to predict the content of nitrate nitrogen in the 0-40 cm soil layer before sowing have been investigated. Data from long-term multifactor ﬁeld experience at the Siberian Research Institute of Farming and Agricultural Chemization of SFSCA RAS for 2013-2018 were used to train the models. The experiment was established on leached chernozem in the central forest-steppe subzone in 1981 in the Novosibirsk region. Considering the characteristics of the statistical sample (observation and analysis data), the main predictors of the models aﬀecting nitrate nitrogen content in soil were identiﬁed. The Bayesian trust network is constructed as an acyclic graph, in which the main (basic) nodes and their relationships are denoted. Network nodes are represented by qualitative and quantitative plot parameters (soil subtype, forecrop, tillage, weather conditions) with corresponding gradations (events). The network assigns a posteriori probability of events for the target node (nitrate-nitrogen content in the 0-40 cm soil layer) as a result of experts completing the conditional probability table, taking into account the analysis of empirical data. Two scenarios were analyzed to test the sustainability of the network and satisfactory results were obtained. The result of the logistic regression is the coeﬃcients characterizing the closeness of the relationship between the dependent variable and the predictors. The coeﬃcient of determination of the logistic regression is 0.7. This indicates that the quality of the model can be considered acceptable for forecasting. A comparative assessment of the predictive capabilities of the trained models is given. The overall proportion of correct predictions for the Bayesian conﬁdence network is 84%, for logistic regression it is 87%.

Com o objetivo de refletir sobre os desafios da prática docente em Educação Física (EF) para propor possibilidades para a Formação Inicial (FI), foi desenvolvida uma elaboração teórica a partir dos dados produzidos em uma pesquisa-ação realizada com dois professores de EF que atuam no Ensino Fundamental. Os resultados indicam que pode haver enorme potencial formativo quando o trabalho pedagógico do professor assume uma posição nuclear na FI de professores de EF. Isto permite vislumbrar possibilidades para maior tomada de consciência acerca da docência, da complexidade do ato educativo e do seu “entorno”, o que inaugura novas possibilidades para que os acadêmicos sejam formados e se formem com maior potencial emancipatório, desenvolvendo uma espécie de “inteligência de navegação”.

Published: December 2021

O presente estudo, fruto de dissertação de mestrado, tem como objetivo compreender as potencialidades/possibilidades da utilização dos MOOCs (Massive Open Online Courses) para a promoção da internacionalização da Educação Superior em casa. Neste sentido, adotou-se a abordagem qualitativa, e como instrumento de pesquisa, a entrevista semiestruturada. Os sujeitos do estudo foram cinco estudantes de graduação de uma Escola Politécnica de Universidade localizada no sul do Brasil. Com esta investigação foi possível vislumbrar os MOOCs como oportunidade de inovação e complemento para os processos de ensino e de aprendizagem nos cursos de graduação, possibilitando, ainda, a internacionalização da educação superior por meio da conexão com professores, estudantes e universidades internacionais.
crônica e a prática escolar da leitura no ensino médio
Authors: Cavalcante Sandra Araujo Lima , Silveira Maria Inez Matoso
Published: December 2021

Este artigo resulta de uma pesquisa de mestrado realizada em 2010 pelo Programa de Pós-Graduação em Educação da Universidade Federal de Alagoas, cujo objetivo foi o de verificar em que medida a crônica contribuía para as práticas de leitura significativa nas aulas de Língua Portuguesa no Ensino Médio, em duas escolas públicas e duas particulares, localizadas em cidade do interior de Alagoas. Os dados coletados permitiram verificar que, embora fosse um gênero apreciado pelos alunos informantes, ainda era atribuída pouca importância à crônica nas escolas onde a pesquisa foi realizada, especialmente nas escolas particulares. Cremos que se trate de uma situação ainda evidente em salas de aula do Ensino Médio na cidade onde ocorreu a coleta dos dados, o que atualiza o estudo aqui apresentado.
Espiritualidade e resiliência na prática das coordenadoras pedagógicas de Ibitiara-BA
Authors: Jorge Romário Silva , Reis Sônia Maria Alves de Oliveira , Marques Tatyanne Gomes
Published: December 2021

O presente artigo discute sobre os desafios enfrentados pelo/a formador/a de professores/as: o/a coordenador/a pedagógico/a. Promove também uma breve reflexão sobre a espiritualidade, recorrendo aos vários sentidos que lhe foram atribuídos ao longo da história, situando-a enquanto elemento indissociável da identidade profissional. Participaram desta pesquisa seis coordenadoras pedagógicas do município baiano de Ibitiara, na Chapada Diamantina, as quais escreveram um relato pessoal expondo as dificuldades encontradas em sua atuação diária e as estratégias utilizadas para superá-las. Por meio da análise qualitativa dessas produções, à luz de estudos sobre a temática em pauta, constatou-se que, somada aos conhecimentos empíricos e didáticos, a espiritualidade concebe a resiliência necessária para o cumprimento da complexa (por vezes, conflitiva) tarefa de conduzir a formação continuada dos/as professores/as, configurando-se, então, em um aspecto importante para as relações profissionais. Essa discussão abre caminhos para o agenciamento de uma formação integral do sujeito-profissional, tanto na escola quanto na universidade, levando em conta suas múltiplas dimensões sociais.
Lesson study no Brasil
Authors: De Oliveira Herlison Nunes , Hitotuzi Nilton , Schwade Kátia Lais
Published: December 2021

Este artigo trata de um levantamento de produções acadêmicas no Brasil sobre a metodologia japonesa Jugyo-Kenkyu (Lesson Study), aplicada à formação inicial e contínua de professores em várias partes do mundo. Para isso, foram realizadas buscas na internet por trabalhos publicados entre 2008 e 2018 com oito descritores. A pesquisa, norteada pelos princípios da Revisão Sistemática, resultou na seleção de 49 publicações oriundas de quatro regiões: Norte, Nordeste, Sudeste e Sul. A análise desse corpus indica avanços das pesquisas, ainda embrionárias, com a Lesson Study no Brasil. Acredita-se que o volume de produções acadêmicas sobre essa metodologia aumente à medida que se amplie a divulgação do seu potencial formativo no país.
Desenvolvimento e avaliação de casos para o ensino de mecanismo de reação
Authors: Nebesnik Kellyn Maria , Da Rosa Elisa Aguayo
Published: December 2021

Casos são narrativas utilizadas para ensinar e que aproximam o conteúdo ao cotidiano e/ou às situações profissionais dos alunos, conferindo-lhes um papel ativo na aprendizagem e maior capacidade de resolver problemas. Nessa perspectiva, o objetivo deste trabalho foi desenvolver casos sobre mecanismos de compostos carbonilados, para uso na graduação. Livros e artigos inspiraram as temáticas para compor os casos que foram avaliados por professores universitários, via questionário. Os resultados evidenciaram que os temas selecionados foram propícios para criar narrativas e relacioná-los às reações químicas. Os docentes mencionaram que têm interesse em aplicar os casos em suas aulas e que perceberam a importância desse método para promover autonomia, contextualização e para colocar os alunos no centro do processo de ensino e aprendizagem. No entanto, não deixaram de refletir que a implementação dos casos exige tempo, habilidade docente e receptividade dos alunos, para que resulte efetiva.

Protagonistas das batalhas: a guerra preta de Angola
Authors: Carvalho Ariane
Published: December 2021

Este artigo tem como objetivo analisar a guerra preta, maior contingente presente nas campanhas militares em Angola do século XVIII. A importância desta tropa foi confirmada pela historiografia especializada, que evidenciou a necessidade de reconhecimento das forças locais africanas e o estabelecimento de alianças políticas para sucesso das campanhas. A guerra preta foi elemento demográfico principal das fileiras militares, o que fez prevalecer os costumes bélicos locais, mesmo nas guerras de iniciativa do governo português.  Sem isso, era impossível aos poderes lusos formar tropas e fazer guerras. Considerando a centralidade desta tropa visamos compreender melhor os elementos que a compõe, os títulos políticos, suas hierarquias, os discursos, e memórias sobre esta força militar.
“N’biri Birin” renasce: praticando a descolonização do currículo escolar a partir das canções do grupo “N’gola Ritmos” (1947-1959)
Authors: Palomo Alves Amanda
Published: December 2021

O artigo apresenta uma proposta de ressignificação de conteúdos relacionados ao colonialismo em Angola com base numa abordagem pedagógica decolonial e inovadora. Para tanto, trabalharemos com canções-lamento do grupo musical angolano “N’gola Ritmos”. As canções, compostas e interpretadas na língua quimbundu, apresentam características importantes relacionadas à cultura nacional, como a tradição oral, e apontam, também, aspectos cruciais relacionados à violência do sistema colonial naquele país. Cumpre destacarmos que a proposta sinaliza possibilidades em torno da descolonização do currículo escolar ao destacar o trabalho de investigação musical realizado pelo líder-fundador do conjunto, Liceu Vieira Dias, e ao iluminar o papel de músicos angolanos que ao valorizarem a alteridade, naquele contexto específico da história, ousaram legitimar suas ações a partir de suas próprias visões de mundo.
Um “astro” do crime: diversos perfis de Antônio Dó pela imprensa norte-mineira
Authors: Meireles Amaral Rodrigues Rejane
Published: December 2021

As denominadas fake News obteveram uma maquiagem de credibilidade com o uso das novas mídias digitais, passando-se por conhecimento noticioso confiável. Todavia, ainda que a internet tenha corroborado e intensificado sua propagação, a divulgação das notícias falaciosas não é um fenômeno recente e tem movido a história da humanidade desde seus primórdios. A atualidade do debate acerca do falseamento das notícias, as fake News, nos remete à pesquisa outrora feita, em que são analisadas algumas publicações dos jornais da época, cuja “produção cultural” foi alimentada pela história de um fazendeiro que viveu na cidade de São Francisco, localizada no Norte de Minas Gerais, conhecido como Antônio Dó. A vida do sitiante teria sido pacata, como a de qualquer outro sertanejo norte-mineiro, não fosse o fato de ter sido alvo de diversas publicações dos jornais locais, que o retratavam como o mais temido e violento bandoleiro do Alto Médio São Francisco.
