Quem conta um conto aumenta um ponto: práticas de retextualização como incentivo à produção de textos multissemióticos
This work discusses the theoretical-methodological possibilities brought by the technological resources for the work with the production of multisemiotic texts in the classroom, based on a theoretical research that highlights the question of multiletramentos and the constitution of the subjects. To illustrate the discussion, the paper presents a research report about a retextualization experience of a story using gifs. The results demonstrate that the epistemological and axiological dimensions presented by the authors studied, if assumed by the teachers, can bring substantial advances to the re-signification of methodologies aimed at the production of texts in multiple contexts.Este trabalho discute possibilidades teórico-metodológicas trazidas pelos recursos tecnológicos para o trabalho com a produção de textos multissemióticos em sala de aula, a partir de uma pesquisa teórica que evidencia a questão dos multiletramentos e a constituição dos sujeitos. Para ilustrar a discussão, o trabalho apresenta um relato de pesquisa sobre uma experiência de retextualização de um conto com uso de gifs. Os resultados evidenciam que as dimensões epistemológicas e axiológicas apresentadas pelos autores estudados, se assumidas pelos professores, podem trazer avanços substanciais para a ressignificação de metodologias voltadas para a produção de textos em múltiplos contextos
FUNDAMENTOS, PESQUISAS, CONTEMPORANEIDADES E TENDÊNCIAS NO ENSINO DE FÍSICA NO BRASIL
On a descriptive and applied basis, this issue of Revista do Professor de Física contains contributions presented at the 2022 Integrated Meetings in Physics and its Teaching (IMPT 2022), which took place at the University of Brasília (UnB) between December 12th and 16th of this year: II National Meeting of the National Professional Master's Degree in Physics Teaching (En-MNPEF), VIII Brazilian School of Physics Teaching (EBEF) and XI Roberto A. Salmeron School of Physics (EFRAS). The themes, references and methodologies are quite diverse, crossing approaches in scientific contents and their didactics; epistemological incursions; psychological relationships of learning; digital materials and technologies applied to teaching; active methodologies; experimentation and investigation; problem solving and conceptualization; resume; evaluation; science-technology-society approaches; literacy, literacy and scientific dissemination; teaching in non-formal spaces; trends and innovations etc. Emphasis was also placed on descriptions resulting from educational applications, including: didactic sequences; instructional materials; computational solutions and other digital technologies; experimental scripts etc. Contributions were made in fundamentals, research, contemporaneity and trends in physics teaching in Brazil, going through classic and frontier themes and approaches that recover social, political, organizational, diversity and inclusion discussions. One feature that can be drawn from the set of texts is the renewed translational attempt to bring academic approaches aimed at teaching Physics closer to the concreteness of performance in Basic Education.Em caráter descritivo e aplicado, o presente número da Revista do Professor de Física contém contribuições apresentadas nos Encontros Integrados em Física e seu Ensino 2022 (EIFE 2022), que tiveram lugar na Universidade de Brasília (UnB) entre os dias 12 a 16 de dezembro deste ano: II Encontro Nacional do Mestrado Nacional Profissional em Ensino de Física (En-MNPEF), VIII Escola Brasileira de Ensino de Física (EBEF) e XI Escola de Física Roberto A. Salmeron (EFRAS). Os temas, os referenciais e as metodologias são bastante diversas, transversalizando abordagens em conteúdos científicos e sua didática; incursões epistemológicas; relações psicológicas da aprendizagem; materiais e tecnologias digitais aplicadas ao ensino; metodologias ativas; experimentação e investigação; resolução de problemas e conceitualização; currículo; avaliação; abordagens ciência-tecnologia-sociedade; alfabetização, letramento e divulgação científica; ensino em espaços não formais; tendências e inovações etc. Também tiveram ênfase descrições decorrentes de aplicações educacionais, abrangendo: sequências didáticas; materiais instrucionais; soluções computacionais e outras tecnologias digitais; roteiros experimentais etc. As contribuições deram-se em fundamentos, pesquisas, contemporaneidades e tendências no ensino de física no Brasil, passando por temas clássicos e de fronteira e por abordagens que recuperam discussões sociais, políticas, organizacionais, de diversidade e inclusão. Uma característica que se pode haurir do conjunto de textos é a renovada tentativa translacional de aproximar abordagens acadêmicas voltadas para o ensino da Física à concretude da atuação na Educação Básica
Vigilância do câncer em Mato Grosso: aspectos metodológicos e operacionais de um projeto de extensão/pesquisa
Objective: To describe the methodological and operational aspects of the Cancer Surveillance Project and its associated factors: population-based and hospital-based registry (VIGICAN), in Mato Grosso (MT). Methods: VIGICAN was divided into two projects: an extension one, which updated the data from the Population-Based Cancer Registry (RCBP) of MT in the period 2008 to 2016; and one of research, which collected primary data, through individual interviews and analysis of medical records of people with a diagnosis of cancer, aged 18 years or over, treated at reference hospitals for oncology. To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, status and health behavior, and environmental exposure. Results: In the períod from 2008 to 2016, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the RCBP Cuiabá and Interior. After validation procedures, fifty thousand incident cases were chosen. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in the interior of the state and 1.4% in other states. Preliminary data revealed that the majority were female (55.0%) and younger than 60 years (54.3%). Among those interviewed, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%) and 32.7% lived close to crops. Conclusion: The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.Objetivo: Descrever os aspectos metodológicos e operacionais do Projeto Vigilância do Câncer e seus fatores associados: registro de base populacional e hospitalar (VIGICAN), em Mato Grosso (MT). Métodos: O VIGICAN se desdobrou em dois projetos: um de extensão, que atualizou os dados dos Registros de Câncer de Base Populacional (RCBP) de MT no período de 2008 a 2016; e um de pesquisa, que coletou dados primários, por meio de entrevistas individuais e análise de prontuários de pessoas com diagnóstico de câncer, com 18 anos ou mais, atendidas em hospitais de referência para oncologia. Para analisar os fatores associados ao câncer, foram coletadas as seguintes variáveis: socioeconômicas e demográficas, suporte social, situação e comportamentos de saúde e exposição ambiental. Resultados: No período de 2008 a 2016, foram notificados nos RCBP Cuiabá e Interior, aproximadamente, 100 mil casos de câncer (incidentes e prevalentes). Após procedimentos de validação, foram eleitos 50 mil casos incidentes. A pesquisa entrevistou 1.012 pacientes, sendo 38,2% residentes nos municípios de Cuiabá e Várzea Grande, 60,4% no interior do estado e 1,4% em outros estados. Os dados preliminares revelaram que a maioria era do sexo feminino (55,0%) e tinha menos de 60 anos (54,3%). Entre os entrevistados, 7,2% relataram fumar tabaco, 15,5% consumiam bebidas alcoólicas (15,5%) e 32,7% moravam próximos a lavouras. Conclusão: O desenvolvimento desses projetos permitiu a integração do ensino com os serviços de saúde e possibilitará o reconhecimento das especificidades e diferentes cenários de exposição e fatores associados ao câncer do território mato-grossense
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest
Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study
Background:
The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms.
Methods:
International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms.
Results:
‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country.
Interpretation:
This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
