A ATUALIDADE DO PENSAMENTO FREIREANO: UMA PONTE DIALÓGICA COM A LINGUÍSTICA APLICADA

The article focuses on Freirean ideas, while comparing the notions of language and identity, themes that are referenced in Freirean work and in Applied Linguistics. It deals with sociological, educational, and language-related aspects, which show us paths for a dialogical approach with Critical Applied Linguistics through a transdisciplinary perspective. The transdisciplinarity is mobilized, in this study, by the connection between the areas of knowledge that have specific objects but that reveal the need to compose a network to interpret the ethical conduct of research. Thusly, we contributed to the discussion about the actuality of the Freirean thought, in a constant search for its acceptance in and for the world. The methodological pathway is bibliographic in nature, presenting the Freirean pedagogy articulated with Applied Linguistics from the perspective of language, dialogue and identities - concerns which arose during the Master's research. We conclude that, in contemporary times, the Freirean pedagogy, collated with Applied Linguistics, is updated in the reaffirmation of the act of educating as an ethical act and, consequently, in the emancipation of the human being, as postulated by Freire and by Applied Linguistics.El artículo enfoca en las ideas freireanas, cotejando las nociones de lenguaje e identidad, temas que son referenciados en la obra de Feire y en la Lingüística Aplicada.

PRÁTICAS DE LETRAMENTO COMO ESTRATÉGIAS DE ENSINO DA ESCRITA NOS ANOS INICIAIS

     O ensino da língua escrita, nos anos iniciais, na perspectiva das práticas de letramento requer do professor (re)atualizar saberes linguísticos e didáticos sobre o funcionamento dos usos da língua escrita, a partir da compreensão dos gêneros discursivos vivenciados socialmente pelos educandos. Esse processo é importante para a alteração de práticas tradicionais de abordagem do objeto linguístico escrita, muitas vezes mecânica e repetitiva. O estudo proposto objetiva abordar a importância da ação pedagógica do professor dos primeiros anos de escolaridade, elegendo estratégias pautadas nas práticas de letramento que ressignifiquem o processo de ensino e aprendizagem. Nesse estudo, conclui-se que o ensino da escrita na escola precisa se revestir da concepção de  práticas de letramento, pois, assim. entendido, possibilitará a exploração no contexto da sala de aula, de diferentes gêneros do discurso explicitando os variados usos e funções que lhes são inerentes numa sociedade letrada.        &nbsp

Psychometric properties of the item-reduced version of the comprehensive general parenting questionnaire for caregivers of preschoolers in a Finnish context

This study evaluates the factorial structure of the item-reduced version of the Comprehensive General Parenting Questionnaire (CGPQ), which assesses five constructs of general parenting. Methods The study uses data from two cross-sectional studies: Study 1 in 2014 (n = 173) and Study 2 in 2015–16 (n = 805). Parents of children aged three to six answered the CGPQ; in Study 1 the 69-item version, and in Study 2 the 29-item version. The reduction was based on the results of the confirmatory factor analyses (CFA) in Study 1. In both datasets, internal consistency, as Cronbach’s alphas and intraclass correlations between the items of each construct, was tested. A combined assessment of the CFA and items response theory evaluated the construct validity and the item importance for the 29-item version, and a further the reduced 22-item version. Results In Study 1, the highest Cronbach’s alphas were shown for the five constructs in the 69-item version. A higher intraclass correlation was found between the constructs in the 69- and 29-item versions, than between the 69- and the 22-item version. However, a high concordance was found between the constructs in the 29- and 22-item versions in both Study 1 and in Study 2 (0.76–1.00). Testing the goodness-of-fit of the CFA models revealed that the 22-item model fulfilled all the criteria, showing that it had a better factorial structure than the 29-item model. Standard estimations ranged from 0.20 to 0.76 in the 22-item version. Conclusion The reduced 22- and 29-item versions of the 69-item CGPQ showed good model fit, the 22-item version the better of the two. These short versions can be used to assess general parenting without overburdening the respondents.Peer reviewe

Production and physicochemical characterization of genotypes of Eugenia uniflora L.

Pitanga (Eugenia uniflora L.) is an exotic fruit species of significant economic importance. However, due to genetic variability, its exploitation is hampered by the lack of homogeneous fruit production. In this scenario, this study aimed to select pitanga genotypes according to the physical and physicochemical parameters of fruits grown under semi-arid conditions. The study was developed at the Federal Rural University of the Semi-Arid Region with genotypes resulting from the open pollination of the pitanga variety ‘Tropicana”. Thirty-nine pitanga genotypes were evaluated for fruit mass, fruit length, fruit diameter, soluble solids (SS), titratable acidity (TA), ascorbic acid (AA), pH, and SS/TA ratio. The pitanga genotypes showed high variability. The clustering method separated the genotypes according to desirable traits. Genotype A12 showed the largest fruit sizes, whereas genotype A8 showed the highest SS and TA contents. Genotypes A2, A13, A34, and A39 showed fruits with the highest AT values. On the other hand, genotypes A11, A16, A45, A9, A26, and A44 showed the most significant contents of pH and SS/TA. Highlights The grouping of two genotypes depends on the environmental conditions, mainly on the effect of two genotypes per year. The analysis of principal components allows selecting the genotypes based on their desired characteristics. The physical and chemical composition of two pitanga fruits are affected by climatic conditions, genotypes and years of cultivation.Pitanga (Eugenia uniflora L.) is an exotic fruit species of significant economic importance.

An Experimental Model of Meningoencephalomyelitis by Rocio Flavivirus in Balb/C Mice: Inflammatory Response, Cytokine Production, and Histopathology

Rocio virus (ROCV) is a flavivirus, probably transmitted by Culex mosquitoes and maintained in nature as a zoonosis of wild birds. Rocio virus caused a human epidemic of severe encephalitis that lasted from 1973 to 1980 in the Ribeira valley, in the southeastern coast of Brazil. After this outbreak, serologic evidence of ROCV circulation has been reported and public health authorities are concerned about a return of ROCV outbreaks in Brazil. We show here a study on the pathogenesis and the physiopathology of ROCV disease in the central nervous system of a Balb/C young adult mice experimental model. The animals were intraperitoneally infected by ROCV and followed from 0 to 9 days after infection, when all of them died. Nervous tissue samples were collected from infected animals for immunohistochemistry and molecular biology analysis. We observed the virus in the central nervous system, the inflammatory changes induced by Th1 and Th2 cytokines, and the final irreversible damage of nervous tissues by neuronal degeneration and apoptosis. These findings can help to better understand the pathogenesis and physiopathology of the human meningoencephalomyelitis by ROCV and other flaviviruses

Evaluation of eleven immunochromatographic assays for SARS-CoV-2 detection: investigating the dengue cross-reaction

COVID-19 disease is spread worldwide and diagnostic techniques have been studied in order to contain the pandemic. Immunochromatographic (IC) assays are feasible and a low-cost alternative especially in low and middle-income countries, which lack structure to perform certain diagnostic techniques. Here we evaluate the sensitivity and specificity of eleven different IC tests in 145 serum samples from confirmed cases of COVID-19 using RT-PCR and 100 negative serum samples from blood donors collected in February 2019. We also evaluated the cross-reactivity with dengue using 20 serum samples from patients with confirmed diagnosis for dengue collected in early 2019 through four different tests. We found high sensitivity (92%), specificity (100%) and an almost perfect agreement (Kappa 0.92) of IC assay, especially when we evaluated IgG and IgM combined after 10 days from the onset of symptoms with RT-PCR. However, we detected cross-reactivity between dengue and COVID-19 mainly with IgM antibodies (5 to 20% of cross-reaction) and demonstrated the need for better studies about diagnostic techniques for these diseases

SARS-CoV-2 reinfection caused by the P.1 lineage in Araraquara city, Sao Paulo State, Brazil

Reinfection by the severe acute respiratory syndrome coronavirus type 2 (SARS-COV-2) has been reported in many countries, suggesting that the virus may continue to circulate among humans despite the possibility of local herd immunity due to massive previous infections. The emergence of variants of concern (VOC) that are more transmissible than the previous circulating ones has raised particular concerns on the vaccines effectiveness and reinfection rates. The P.1 lineage was first identified in December 2020 in Manaus city and is now globally spread. We report the first case of reinfection of SARS-CoV-2 caused by the P.1 variant outside of Manaus. The potential of these new variants to escape naturally and vaccine- induced immunity highlights the need for a global vigilance

Left ventricular systolic dysfunction predicted by artificial intelligence using the electrocardiogram in Chagas disease patients-The SaMi-Trop cohort

BACKGROUND: Left ventricular systolic dysfunction (LVSD) in Chagas disease (ChD) is relatively common and its treatment using low-cost drugs can improve symptoms and reduce mortality. Recently, an artificial intelligence (AI)-enabled ECG algorithm showed excellent accuracy to detect LVSD in a general population, but its accuracy in ChD has not been tested. OBJECTIVE: To analyze the ability of AI to recognize LVSD in patients with ChD, defined as a left ventricular ejection fraction determined by the Echocardiogram ≤ 40%. METHODOLOGY/PRINCIPAL FINDINGS: This is a cross-sectional study of ECG obtained from a large cohort of patients with ChD named São Paulo-Minas Gerais Tropical Medicine Research Center (SaMi-Trop) Study. The digital ECGs of the participants were submitted to the analysis of the trained machine to detect LVSD. The diagnostic performance of the AI-enabled ECG to detect LVSD was tested using an echocardiogram as the gold standard to detect LVSD, defined as an ejection fraction <40%. The model was enriched with NT-proBNP plasma levels, male sex, and QRS ≥ 120ms. Among the 1,304 participants of this study, 67% were women, median age of 60; there were 93 (7.1%) individuals with LVSD. Most patients had major ECG abnormalities (59.5%). The AI algorithm identified LVSD among ChD patients with an odds ratio of 63.3 (95% CI 32.3-128.9), a sensitivity of 73%, a specificity of 83%, an overall accuracy of 83%, and a negative predictive value of 97%; the AUC was 0.839. The model adjusted for the male sex and QRS ≥ 120ms improved the AUC to 0.859. The model adjusted for the male sex and elevated NT-proBNP had a higher accuracy of 0.89 and an AUC of 0.874. CONCLUSION: The AI analysis of the ECG of Chagas disease patients can be transformed into a powerful tool for the recognition of LVSD

O Memorial de Imigração Polonesa em Curitiba: dinâmicas culturais e interesses políticos no âmbito memoralista

Neste artigo, analisa-se o conceito de memorial, considerando as atuais definições de Museu propostas pelo Conselho Internacional de Museus e pelo Instituto Brasileiro de Museus, tendo como objeto de investigação o Memorial de Imigração Polonesa de Curitiba. Evidenciam-se a importância e a complexidade no trato com o patrimônio e as dificuldades de pensá-lo a partir dos sujeitos e das referências culturais de determinado grupo em contraponto aos interesses políticos e econômicos; no caso em questão, voltadas às necessidades da política de city marketing como estratégia de construção da imagem da cidade. Para tanto, foram considerados os perfis de atuação dos memoriais em diferentes partes do mundo, na tentativa de delimitação conceitual, exemplificando-se a pluralidade de temas e formatos dessas instituições no âmbito nacional e global. As discussões levantadas permitem pensar que os Museus Memoriais desempenham as atividades de um memorial no âmbito museológico, confirmando a ambivalência dessas duas instituições e sua interface privilegiada com o poder político.This article analyzes the memorial concept, considering the Museum definition presented by the International Council of Museums and the Brazilian Institute of Museums. The aim of this study was the Curitiba Polish Immigration Memorial. It highlights the importance and complexity in dealing with the heritage and the difficulties of thinking it from the individuals and the cultural references of certain groups as opposed to political and economic interests; in this case the needs of the city marketing policy as city image building strategy. Therefore, the memorials performance profiles in different parts of the world in an attempt to conceptual definition, exemplifying the diversity of themes and formats of these institutions at the national and global levels. The discussions show that it is possible to consider that the Memorials Museums perform the same activities of a memorial within the museological context, confirming the ambivalence of these two institutions and prime interface with political power
