Ο ιατρικός τουρισμός ως μοχλός οικονομικής ανάπτυξης
Authors: Μπατάκης Δημήτριος
Published: May 2021

Ο ιατρικός τουρισμός μπορεί να αποτελέσει τον βασικό μοχλό του τουρισμού αλλά και της οικονομίας της Ελλάδας, με την εξέλιξη που έχει τα τελευταία χρόνια σε όλο τον κόσμο. Ο ιατρικός τουρισμός αναφέρεται σε άτομα που έχουν την επιθυμία να χρησιμοποιήσουν ιατρικές υπηρεσίες σε μία χώρα του εξωτερικού, συνδυάζοντας το ιατρικό μέρος με τις διακοπές. Οι βασικές υπηρεσίες που παρέχονται είναι η ιατρική περίθαλψη, όλων των ειδών, όπως και οι δραστηριότητες ευεξίας, π.χ. ιαματικά λουτρά. Το κύριο πλεονέκτημα του ιατρικού τουρισμού είναι η αύξηση των εσόδων της χώρας που επιλέγει το άτομο να μεταβεί για τις δραστηριότητές του και η λήψη υγειονομικών υπηρεσιών σε χαμηλότερη τιμή από τον τουρίστα υγείας, σε συνδυασμό με τις διακοπές. Όμως υπάρχουν και τα μειονεκτήματα όπως η έλλειψη κανονισμών παροχής υπηρεσιών υγείας και πιστοποίησης, ενώ για τον χρήστη είναι η μη κάλυψη των εξόδων από τα ασφαλιστικά ταμεία και η μεταφορά που ενδέχεται να επιβαρύνει την υγεία του. Πέρα απ’ όλα αυτά, η ζήτηση των υπηρεσιών του ιατρικού τουρισμού συνεχώς αυξάνονται και οι λόγοι είναι η αύξηση της γήρανσης του πληθυσμού, η αύξηση δραστηριοτήτων ευεξίας, η αυξημένη ζήτηση υπηρεσιών υγείας σε αναπτυσσόμενες χώρες και οι λίστες αναμονής σε νοσοκομεία των ανεπτυγμένων χωρών. Εξαιτίας αυτών των λόγων πολλές χώρες έχουν εφαρμόσει με επιτυχία τον ιατρικό τουρισμό, όπως η Ινδία και η Ταϋλάνδη από Ασία, και η Ιταλία και η Γαλλία από Ευρώπη, ενώ ιδιαίτερες προσπάθειες γίνονται και στις χώρες της Ν. Αφρικής και Ν. Αμερικής. Σχετικά με την Ελλάδα, η χώρα μας έχει ως βασικό πλεονέκτημα το κλίμα της, την πολιτιστική κληρονομιάς της και την μεσογειακή διατροφή. Επίσης, ο τουρισμός βρίσκεται σε ανεπτυγμένα επίπεδα, έχοντας σε όλη την επικράτεια πολυτελή ξενοδοχεία και έμπειρο προσωπικό. Η εμπειρία του προσωπικού όμως ισχύει και για τις υγειονομικές υπηρεσίες, σε συνδυασμό με τα πανεπιστημιακά νοσοκομεία που υπάρχουν και τις σύγχρονες κλινικές που έχουν δημιουργηθεί τα τελευταία χρόνια. Ο σκοπός της παρούσης έρευνας είναι η διατύπωση των αντιλήψεων των ατόμων που ασχολούνται με τον τουρισμό και τις υπηρεσίες υγείας στην Κρήτη, σε σχέση με τον ιατρικό τουρισμό, για να φανούν οι προοπτικές του στην χώρα μας. Για τις ανάγκες της έρευνας δομήθηκαν ερωτηματολόγια, τα οποία διενεμήθησαν σε ξενοδοχεία της Κρήτης τεσσάρων και πέντε αστέρων, σε ιατρικούς συλλόγους του νησίου και σε τουρίστες που επισκέφθηκαν το αέροδρομιο Ιώαννης Δασκαλογίαννης των Χανίων. Τα ερωτηματολόγια εστάλησαν μέσω ηλεκτρονικής αλληλογραφίας στις διευθύνσεις των ξενοδοχείων και των ιατρών, ενώ στους τουρίστες ακολουθήθηκε μία διαφορετική μέθοδος. Τα αντίστοιχα ερωτηματολόγια μοιράστηκαν και απαντήθηκαν από αυτους στο αεροδρόμιο των Χανίων με την συμβολή του ΜΑΙΧ (Μεσογειακό Αγρονομικό Ινστιτούτο Χανίων).
Molecular study of sapovirus in acute gastroenteritis in children: a cross-sectional study
Authors: Zaki Maysaa El Sayed , Shrief Raghdaa , Hassan Rasha H.
Published: May 2021

Background: Sapovirus has emerged as a viral cause of acute gastroenteritis. However, there are insufficient data about the presence of this virus among children with acute gastroenteritis. The present study aimed to evaluate the presence of sapovirus in children with acute gastroenteritis by reverse transcriptase-polymerase chain reaction (RT-PCR).

Methods: A cross-sectional study enrolled 100 children patients with acute gastroenteritis from outpatient clinics with excluded bacterial pathogens and parasitic infestation. A stool sample was collected from each child for laboratory examination. Each stool sample was subjected to study by direct microscopic examination, study for rotavirus by enzyme-linked immunoassay (ELISA) and the remaining sample was subjected to RNA extraction and RT- PCR for sapovirus.

Results: The most frequently detected virus was rotavirus by ELISA (25%). RT-PCR detected sapovirus in 7% of the stool samples. The children with sapovirus were all from rural regions and presented mainly during the winter season in Egypt (42.9%). The main presenting symptoms were fever (71.4%) and vomiting (57.1%). None of the children with sapovirus had dehydration. Rotavirus was significantly associated with sapovirus infections in 5 patients (71.4%, P=0.01). There was an insignificant difference between symptoms of gastroenteritis in children with sapovirus and children with gastroenteritis without sapovirus as regards vomiting (P=0.7), fever (P=0.46), and abdominal pain (P=0.69).

Conclusion: The present study highlights the emergence of sapovirus as a frequent pathogen associated with acute gastroenteritis in children. There is a need for a national survey program for the study of sapovirus among other pathogens associated with acute gastroenteritis for better management of such infection.
Dense Orbits of the Bayesian Updating Group Action
Authors: Hellman Ziv , Levy Yehuda John
Published: May 2021

We study dynamic properties of the group action on the simplex that is induced by Bayesian updating. We show that, generically, the orbits are dense in the simplex, although one must make use of the entire group, hence departing from straightforward Bayesian updating. We demonstrate also the necessity of the genericity of the signalling structure, a relationship to descriptive set theoretical concepts, and applications thereof to repeated games of incomplete information, as well a strengthening concerning the group action on itself.

Authors: Curioso Vílchez Iván Carlos
Published: May 2021

Há uma falta de pesquisa no campo da educação especial sobre a inclusão de estudantes com deficiência visual no espaço universitário. Este trabalho tem como objetivo identificar as características dos recursos e serviços disponíveis para o atendimento dos alunos com deficiência visual em uma universidade privada em Lima, Peru. Se realizaram entrevistas semiestruturadas com 6 estudantes universitários com deficiência visual para compreender melhor suas demandas educacionais. Os participantes desta pesquisa têm entre 20 e 48 anos. A média de idade é de 27,5 anos. Os dados foram transcritos e depois de uma análise de conteúdo se identificou cinco categorias temáticas. Em um primeiro âmbito, destaca-se as dificuldades com a gestão da universidade para a adaptação e digitalização dos textos acadêmicos. Em um segundo âmbito, identifica-se a falta de estratégias e técnicas para adequação de suas tarefas e avaliação pelos professores. Em um terceiro âmbito, menciona-se a carência de formação e capacitação dos funcionários e da comunidade universitária a respeito das suas atitudes sociais para um atendimento adequado a este grupo. Em um quarto âmbito, realça-se os problemas com a acessibilidade no câmpus universitário. Finalmente, destacou-se algumas recomendações para a gestão universitária baseado no monitoramento da inclusão. Conclui-se que as políticas desta universidade no campo da deficiência ainda estão em construção e devem ser fiscalizadas, com base nas normas legais nacionais e internacionais.
CONVERGÊNCIAS E DIVERGÊNCIAS ENTRE AS CONCEPÇÕES DE EDUCAÇÃO DO E NO CAMPO: ALGUMAS CONSIDERAÇÕES
Authors: Pereira Waldiléia do Socorro Cardoso , Freitas Wansley Ferreira
Published: May 2021

A presente teorização é resultante de estudos realizados no curso de pós graduação em educação e tem como desafio refletir acerca da elaboração dos conceitos “Educação do Campo” e “Educação no Campo”. O objetivo é destacar elementos que possam conduzir nossa reflexão no sentido de identificar possíveis divergências e convergências entre as duas concepções e como se constituem nos coletivos. Para entender esse movimento buscamos realizar leituras no arcabouço constituinte do movimento “Por uma Educação do Campo” também do “Grupo de Estudos e Pesquisa sobre Educação no Campo” ambos com robusta e sólida produção. Destaca-se a intencionalidade subjetiva/objetiva subentendida nas preposições “no” e “do” que antecedem a palavra “campo”, que não nega o óbvio compromisso com a bandeira social/política por parte de ambos os coletivos. Apesar de algumas divergências, o mote central está na luta contra o sistema capitalista que inclui a persistência pela escolarização qualificada no campo. Esses campos, cerrados, várzeas, florestas e pantanais, esses rurais geograficamente tão diversos vão incorporando a materialidade de tantas gentes brasileiras e com isso os entendimentos são tão diversos quanto podem ser a própria subjetividade humana que cimenta o conhecimento que pode constituir os conceitos que ocupam espaço em sua representatividade.

Published: May 2021

O objetivo geral deste artigo consiste em (re)conhecer as repercussões da pandemia de COVID-19 na saúde (prática social e política pública) de sujeitos e comunidades do campo nas quais alunos/as do curso de Licenciatura em Educação do Campo da Faculdade de Educação da Universidade Federal de Minas Gerais (LECampo/FaE/UFMG) trabalham e/ou residem. Esta pesquisa está articulada ao projeto de extensão “Povos do Campo e a pandemia do COVID-19”, criado em abril de 2020. Os caminhos metodológicos da investigação consistiram na aplicação de questionários com questões fechadas e abertas, respondidos por 36 estudantes na primeira etapa (final de abril/início de maio de 2020) e por 46 estudantes na segunda etapa (meados de julho de 2020). Os dados foram analisados através da análise de conteúdo e foram construídas categorias em diálogo com alguns princípios do SUS: a) práticas de saúde frente à pandemia; b) acesso e divulgação de informações; c) ações em saúde pública, que contemplou o acesso a serviços de saúde, o atendimento sistêmico e o estabelecimento de prioridades e d) relação campo-cidade. Com a interiorização do Covid-19, ficou evidente a fragilidade no sistema de saúde com centralização nos centros urbanos, evidenciando a precarização histórica dos atendimentos nas cidades pequenas e no campo. Entre outros resultados, há persistência do reduzido acesso às políticas públicas, especialmente de saúde, por povos do campo no país. Ressalte-se o lugar da luta pela Educação do Campo como estratégia em defesa da valorização dos trabalhadores rurais, da agricultura familiar, das formas de vida e desenvolvimento campesino.

Published: May 2021

Este estudo tem o objetivo de mapear e analisar a produção acadêmica sobre Educação no Campo no Brasil produzida entre 2011 e 2015 que trazem resultados sobre os ideários pedagógicos que orientam as concepções “do” e “no” campo. O recorte temporal se justifica devido a existência de pesquisas anteriores que trazem dados do período anterior. As discussões e os interesses sobre educação no meio rural têm se tornado alvo de diversos grupos e também utilizadas como parâmetros para a criação de políticas públicas para o campo e a sistematização sobre essa produção se torna fundamental para compreender essa conjuntura. Quanto a metodologia, segue-se os princípios da pesquisa qualitativa e quantitativa com enfoque bibliográfico. Foram utilizados os portais CAPES e La Referencia como base de dados. A partir de um recuo histórico para compreensão da constituição do Movimento Por uma Educação do Campo, a realização desta pesquisa permitiu compreender as concepções pedagógicas que influenciam as práticas pedagógicas de professores em escolas no campo, seguido de um levantamento da produção científica que identificou os interesses de pesquisas dessa área, incluindo as regiões onde são desenvolvidas.
FORMAÇÃO DE PROFESSORES PARA ESCOLAS RURAIS E A CERTIFICAÇÃO DOCENTE NO ESTADO DE SÃO PAULO EM 2010
Authors: Basso Jaqueline Daniela , Dos Santos Maria Cristina
Published: May 2021

Historicamente a educação do campo surgiu a partir de demanda das populações do campo envolvidas na luta pela terra, sobretudo a partir de meados da década de 1980, quando o Movimento dos Trabalhadores Rurais sem Terra – MST se organizou e vem se constituindo, de lá para cá, como uma força impulsionadora exercendo pressão sobre o Estado para a garantia de direitos sociais, tanto o de acesso à terra e melhoria nas condições de vida dos trabalhadores do campo, quanto de acesso à educação escolar. Deste modo, objetivamos discutir algumas iniciativas de formação docente para o trabalho nas escolas rurais bem como os níveis de certificação docente no estado de São Paulo no final da primeira década do século XXI. Para isso, lançamos mão de revisão bibliográfica articulada à análise estatística a partir dos Microdados do Censo Escolar de 2010 que foram extraídos com auxílio do Software SPSS. A partir disto, concluímos que ocorreram avanços nas condições de formação de professores que atuam nas escolas do campo, de modo geral, do início do século XX para cá. Entretanto, iniciativas específicas, identificadas com o trabalho e as lutas daqueles que vivem no campo ainda são pontuais e resultantes das lutas dos movimentos sociais do campo, que ganharam força sobremaneira a partir de meados da década de 1980, portanto em um período histórico recente.
Electrical Properties Predict Wheat Leaf Moisture

Published: May 2021

Highlights

A non-destructive prediction model for moisture content of wheat leaves was established based on electrical properties.

The model based on a single property (capacitance or resistance) was improved by using both properties.

The model accurately detected the moisture content of wheat leaves in real-time to avoid irrigation lag.

The results provide a basis for real-time and targeted water-saving irrigation of winter wheat in an arid region.

Abstract. In this study, we aimed to establish a non-destructive and rapid approach to monitor the moisture content of wheat leaves in Southern Xinjiang, China, and promptly acquire information on the physiological water demand of crops to guide precision irrigation. Wheat leaves were used as the research object. Using a custom-made clamped parallel-plate capacitor and LCR digital bridge meter, we determined the electrical properties (capacitance and resistance) of wheat leaves with various moisture contents within a frequency range from 0.12 to 100 kHz. Moreover, we explored the correlation between leaf moisture content and the electrical properties. Our data showed that leaf moisture exhibited the best correlation with the electrical properties at 50 kHz. Under these optimized conditions, a model for moisture measurement was established using a single-parameter method (capacitance or resistance). However, the estimated standard errors (RMSE) of this method were 3.29% (for resistance) and 3.49% (for capacitance), which were greater than the standard error of the measured moisture content (2%). Therefore, we developed an improved model using a two-parameter method (capacitance and resistance), and the estimated standard error was 2.68%, which was more feasible for predicting moisture content compared with the single-parameter method. The model was validated using eight groups of wheat leaf samples at the turning-green stage and the jointing stage, and the RMSE values were less than 2%. Our findings provide a scientific basis for real-time and targeted water-saving irrigation of wheat in arid areas of Southern Xinjiang. Keywords: Electrical property, Model, Moisture content, Precision irrigation, Wheat leaves.

Published: May 2021

An easy and fast fabrication strategy to obtain Photochromic Films (PFs) for naked-eye detection of oxygen is presented. These PFs are based on the photoreductive activity of TiO2 nanoparticles combined with the redox-driven color switching property of methylene blue, embedded in a photocurable and tunable air-permeable polyethylene glycol diacrylate (PEGDA) matrix. The PF is fabricated by a single-step process: the UVA light exposure initiates the polymerization and simultaneously reduces the blue-color dye in its colorless form. The resulting PF exhibits fast discoloration and modulable recoloration time in the air. The tunability of PFs color-switching can be used for engineering colorimetric sensors with preset oxygen responsive ranges to fulfill specific application requirements.

Published: May 2021

Hybrid fluorescent cholesteric liquid crystalline (CLC) materials are representatives of “smart” soft matter, and are characterized by light emission that can be flexibly controlled by various external stimuli. This fact is due to the many possibilities for potential applications in the fields of photonics and optics stimulating design, and study of this type of hybrid materials. Here, we report on the optical and fluorescence properties of the hybrid CLC material based on a low-molecular-weight CLC matrix and CdSe/ZnS quantum dots (QDs) stabilized by LC diblock copolymers. The hybrid CLC material is characterized by the cholesteric phase in a wide temperature range, the high loading of QDs, and no QD aggregation. We demonstrate that the cholesteric stop band alters characteristics of the QD emission due to the resonance effect. This makes the polarization state and wavelength of the QD emission thermo- and angle-dependent. This work provides a way for the design of a wide range of field-controllable photonic devices for various applications.
Drainage-structuring of ancestral variation and a common functional pathway shape limited genomic convergence in natural high- and low-predation guppies

Published: May 2021

Studies of convergence in wild populations have been instrumental in understanding adaptation by providing strong evidence for natural selection. At the genetic level, we are beginning to appreciate that the re-use of the same genes in adaptation occurs through different mechanisms and can be constrained by underlying trait architectures and demographic characteristics of natural populations. Here, we explore these processes in naturally adapted high- (HP) and low-predation (LP) populations of the Trinidadian guppy, Poecilia reticulata. As a model for phenotypic change this system provided some of the earliest evidence of rapid and repeatable evolution in vertebrates; the genetic basis of which has yet to be studied at the whole-genome level. We collected whole-genome sequencing data from ten populations (176 individuals) representing five independent HP-LP river pairs across the three main drainages in Northern Trinidad. We evaluate population structure, uncovering several LP bottlenecks and variable between-river introgression that can lead to constraints on the sharing of adaptive variation between populations. Consequently, we found limited selection on common genes or loci across all drainages. Using a pathway type analysis, however, we find evidence of repeated selection on different genes involved in cadherin signaling. Finally, we found a large repeatedly selected haplotype on chromosome 20 in three rivers from the same drainage. Taken together, despite limited sharing of adaptive variation among rivers, we found evidence of convergent evolution associated with HP-LP environments in pathways across divergent drainages and at a previously unreported candidate haplotype within a drainage.
An AMP-activated protein kinase complex with two distinctive alpha subunits is involved in nutritional stress responses in Trypanosoma cruzi

Published: May 2021

Trypanosoma cruzi, the etiological agent of Chagas disease, has a digenetic life cycle. In its passage from the insect vector to the mammalian host, and vice versa, it must be prepared to cope with abrupt changes in environmental conditions, such as carbon source, pH, temperature and osmolarity, in order to survive. Sensing and signaling pathways that allow the parasite to adapt, have unique characteristics with respect to their hosts and other free-living organisms. Many of the canonical proteins involved in these transduction pathways have not yet been found in the genomes of these parasites because they present divergences either at the functional, structural and/or protein sequence level. All of this makes these pathways promising targets for therapeutic drugs. The AMP-activated protein kinase (AMPK) is a serine/threonine kinase activated by environmental stresses such as osmotic stress, hypoxia, ischaemia and exercise that results in reduction of ATP and increase of AMP levels. Thus, AMPK is regarded as a fuel gauge, functioning both as a nutrient and an energy sensor, to maintain energy homeostasis and, eventually, to protect cells from death by nutrient starvation. In the present study we report the characterization of AMPK complexes for the first time in T. cruzi and propose the function of TcAMPK as a novel regulator of nutritional stress in epimastigote forms. We show that there is phosphotransferase activity specific for SAMS peptide in epimastigotes extracts, which is inhibited by Compound C and is modulated by carbon source availability. In addition, TcAMPKα2 subunit has an unprecedented functional substitution (Ser x Thr) at the activation loop and its overexpression in epimastigotes led to higher autophagic activity during prolonged nutritional stress. Moreover, the over-expression of the catalytic subunits resulted in antagonistic phenotypes associated with proliferation. Together, these results point to a role of TcAMPK in autophagy and nutrient sensing, key processes for the survival of trypanosomatids and for its life cycle progression.

Published: May 2021

Background

The success of vaccination efforts to curb the COVID-19 pandemic will require broad public uptake of immunization and highlights the importance of understanding factors associated with willingness to receive a vaccine.

Methods

U.S. adults aged 65 and older enrolled in the HeartlineTM clinical study were invited to complete a COVID-19 vaccine assessment through the HeartlineTM mobile application between November 6–20, 2020. Factors associated with willingness to receive a COVID-19 vaccine were evaluated using an ordered logistic regression as well as a Random Forest classification algorithm.

Results

Among 9,106 study participants, 81.3% (n = 7402) responded and had available demographic data. The majority (91.3%) reported a willingness to be vaccinated. Factors most strongly associated with vaccine willingness were beliefs about the safety and efficacy of COVID-19 vaccines and vaccines in general. Women and Black or African American respondents reported lower willingness to vaccinate. Among those less willing to get vaccinated, 66.2% said that they would talk with their health provider before making a decision. During the study, positive results from the first COVID-19 vaccine outcome study were released; vaccine willingness increased after this report.

Conclusions

Even among older adults at high-risk for COVID-19 complications who are participating in a longitudinal clinical study, 1 in 11 reported lack of willingness to receive COVID-19 vaccine in November 2020. Variability in vaccine willingness by gender, race, education, and income suggests the potential for uneven vaccine uptake. Education by health providers directed toward assuaging concerns about vaccine safety and efficacy can help improve vaccine acceptance among those less willing.

Resilience and coping strategies in relation to mental health outcomes in people with cancer
Authors: Macía Patricia , Barranco Mercedes , Gorbeña Susana , Álvarez-Fuentes Esther , Iraurgi Ioseba
Published: May 2021

Considering the importance of psychological variables on health-related processes, this study investigated the role of resilience and coping strategies in relation to health. The aim of this research was to explore the underlying association between these aspects for the better understanding of the effect of psychosocial variables on mental health in cancer. This information could lead to the design of adapted psychological interventions in cancer. Participants with different diagnosis of cancer were recruited (N = 170). They came from the Spanish Association Against Cancer of Biscay. Resilience was measured with the 10 items Connor-Davidson Resilience Scale, coping with the Cognitive Emotion Regulation Questionnaire and mental health was measured as a global indicator through the SF-12 and the GHQ-12. A structural equation model (SEM) was conducted to test the effects between the constructs. Results showed that resilience and coping were significantly associated. Results reflected an absence of significant correlation between adaptive and disadaptive coping strategies. Resilience was the factor that most correlated with health outcomes (β = –.45, p < .001). However, disadaptive coping strategies did not correlate with resilience or mental health indicators. Findings in this study underscore the positive contribution of high levels of resilience and an adaptive coping on participants´ level of health. Disadaptive coping strategies did not reflect any positive relation with resilience or health indicators. Thus, promoting resilience and adaptive coping could be a significant goal for psychosocial and educational interventions in people with cancer.
El Boletín de Educación Paraguaya en los años 1950 y las prescripciones para los profesores
Authors: Larrea Viera Cinthya Lorena , Moreira Kênia Hilda
Published: May 2021

Tratamos de identificar y analizar los contenidos prescritos en la primera fase del Boletín de Educación Paraguaya - Revista Mensual de Orientación e Información Pedagógica, entre 1956 y 1959, bajo el gobierno dictatorial de Alfredo Stroessner. Partimos de la hipótesis de que este impreso estimuló nuevas representaciones alrededor del quehacer docente en Paraguay, a la luz de los preceptos de la escuela activa, teniendo a los docentes como lectores visados. Cuestionamos las prescripciones para establecer nuevos patrones de comportamiento y actitudes para los profesores paraguayos al analizar los primeros 37 números de la revista. Como referenciales teórico-metodológicos de análisis nos basamos en la historia cultural y en las bibliografías sobre historia de la educación paraguaya. Concluimos que los estímulos divulgados en el Boletín para producir nuevas representaciones sobre la figura del profesor, en el Paraguay en la década de 1950, lo ubican como protagonista de la Reforma Educativa Paraguaya de 1957, inculcándoles un modelo de conducta ante la sociedad, una autoridad moral y saberes científicos modernos y patrióticos.

Published: May 2021

En el presente artículo damos a conocer las características de las revistas publicadas entre siglos, vale decir, las que comenzaron en la última década del siglo xx y las que emergieron en estas dos primeras décadas del nuevo siglo xxi. Las revistas educativas peruanas, otrora impresas, han migrado significativamente hacia la virtualidad; las que no lo hicieron han reducido la visibilidad de los artículos académicos que en ellas se publican. El mayor número de estas revistas están vinculadas a las universidades como agencias editoriales; no obstante, también se tienen revistas asociadas a organizaciones sociales, al Gobierno y al sindicato docente. Estas últimas conservan su función divulgativa y generadora de debate sobre las políticas públicas; en tanto que las otras se muestran como revistas que comunican los resultados de las investigaciones en el campo educativo.
Formação de professores e métodos de ensino em Brasil na perspectiva do periódico a instrução pública (1872-1875)
Authors: Lima Sara Talitiane Viana Machado Leandro de , Netto Mario Borges , Machado Maria Cristina Gomes
Published: May 2021

O objetivo é analisar a preocupação sobre a necessidade de propagação de métodos de ensino para a formação de professores expressa no periódico A Instrução Pública. Fundado por José Carlos Alambary Luz, o periódico foi publicado na capital imperial do Brasil, entre os anos de 1872 e 1875.

CARTOGRAFIA DOS TERRITÓRIOS DA ESCOLA: MAPEANDO ESPAÇOS HETEROTÓPICOS DE LAZER QUE POSSIBILITAM INFLEXÕES DE APRENDIZAGEM EM GÊNERO NO BRINCAR DE CRIANÇAS.
Authors: Veloso Silva Leandro
Published: May 2021

Este estudo busca relatar alguns passos e propostas de reconhecimentos de uma pesquisa de doutorado – PPGIEL – EEFFTO/UFMG, que se insere no campo das Ciências Sociais, Humanas e nos Estudos do Lazer, pela proposição de abordar e problematizar questões no entorno do sujeito social ‘criança’ no seu processo de conhecer e aprender no decorrer do ‘brincar’ nos momentos de ‘lazer’ da/na ‘infância’ nos territórios da Escola. Nesse sentido, tem como objetivo se movimentar com a escola e com seus atores e sujeitos sociais para identificar nesses territórios, espaços heterotópicos de lazer, e problematizar que esses espaços possibilitam inflexões de aprendizagem em gênero, por meio das práticas sociais presentes no(s) brincar(es) da(s) infância(s). Para tanto, se subsidia num movimento de uma pesquisa bibliográfica, ancorada nos caminhos metodológicos desenhados por meio de uma pesquisa qualitativa e pós-crítica, tendo como rota a abordagem de uma cartografia.
A/R/TOCARTOGRAFIAS PARA DECOLONIZAR NOSSOS SENTIDOS SOBRE OS CORPOS MINORITÁRIOS

Published: May 2021

Num movimento a/r/tográfico (inter-relação textual, imagética com problematizações e a construção de narrativas que não se esquadrinham pela lógica acadêmica) e com aportes teóricos decoloniais do sul global, discutimos a naturalização de certos discursos na biologia e nas artes visuais com o propósito de problematizar a colonização dos sentidos para os corpos, gêneros e as sexualidades minoritárias. Saberes colonizados adensam as Pedagogias Culturais e guiam entendimentos que apagam a outridade e os pertencimentos de classe, etnia, gênero, de lugar. Trabalhamos com imagens e representações como potências poéticas e epistêmicas, causadoras de abalos no regime de colonialidade do poder/saber e como brechas e fraturas dos discursos normativos, coloniais, biológicos e naturalizados.

O presente texto, tecido a várias mãos, apresenta o diálogo entre duas pesquisas realizadas no programa de pós-graduação em educação da Universidade Federal de Lavras, no que tange as relações étnico-raciais e as experienciações artísticas. O lócus do vigente estudo transita entre turmas das séries iniciais do Ensino Fundamental e da Educação Infantil, situadas, respectivamente, no Campo das Vertentes e no Sul de Minas Gerais. Ambas investigações se pautaram nos referenciais teórico-metodológicos pós-estruturalistas e nos estudos foucaultianos para problematizar as relações de saber-poder que navegam nos engalfinhamentos, sendo enfrentamento, pulsando resistências. O material empírico foi produzido na realização de oficinas pedagógicas, previamente elaboradas, que borbulharam problematizações referentes a representatividade da negritude. Atravessados pelo teatro e pelas artes plásticas, encontramos nas expressões e falas das crianças a negação e/ou a marginalização das pessoas negras, o que nos inquietou e nos lançou a esse campo investigativo, visando problematizar as desigualdades de raça/etnia que reverberam no ambiente escolar.

El género ilimitado: Márgenes, rupturas y transgresiones en el cine luso-hispánico
Authors: Barraza Vania
Published: May 2021

Sea por sus características formales, estilísticas o por su orientación comercial, el estudio de los géneros cinematográficos constituye una práctica reducida. Como no existe una definición estable sobre el cine de género, su clasificación se renueva con regularidad. Los estudios feministas y LGBTQ+ también conforman un campo disciplinar en permanente redefinición. Así, tanto el cine de convenciones genéricas como la teorización del género y la disidencia sexual coinciden en ser fuentes de conocimiento ilimitado. En tal sentido, los artículos del presente número monográfico exploran cómo el cine de género se adhiere, resiste y subvierte normativas propias de una hegemonía heteropatriarcal.
Destabilizing Gender and Genre: Queering the Body in Libertarias and Land and Freedom
Authors: Everly Kathryn A.
Published: May 2021

Libertarias (1996) and Land and Freedom (1995) explore the complex situation of women militia during the Spanish Civil War. A queer reading of the female body in these films highlights wartime female masculinity (Halberstam) and female solidarity. In renegotiating worn expectations of sexuality and gender, the films question and ultimately redefine the wartime docudrama genre. The queering of gender and genre leads to alternative versions of history that upend the very idea of historical accuracy. The female bodies in the films transgress entrenched binary gender norms, thus creating a uniquely queer representation of female solidarity in the docudrama genre.
