Exploring cultural dynamism of ethnomodelling as a pedagogical action for students from minority cultural groups.
No full textMathematics education is inherent to the discourse of globalization, which often states that mathematical knowledge is universal. Certain global mathematical techniques and procedures found in many mathematics curricula around the world often discourage students to engage in creating their own mathematical knowledge. This suggests that dominant cultural values are defined as universal or at the very least labeled as normative, while peripheral mathematical knowledge is tagged as merely simplistic, primitivistic, folkloristic, and/or as forms of obsolete systems. Our main purpose here is to discuss how ethnomodelling promotes a holistic understanding of local and global approaches in mathematics education, which contributes to the development of a glocal comprehension of mathematical practices developed by members of distinct cultures, which means placing them at the center of the educational process. Through the development of ethnomodelling, this pedagogical action promotes connections between day-to-day knowledge and systematized school curricula. Thus, this theoretical article demonstrates how we might consider situating local mathematical practices (margins) at the center (glocal) of the mathematics education process by decentering globalized mathematical knowledge in the search for peace and social justice

Evidências do uso do Critério de Adequação Interacional no planejamento de aulas sob a perspectiva da gamifcação : um estudo com futuros professores de Matemática.
No full textO presente estudo tem por objetivo analisar o Critério de Adequação Didática Interacional revelado por dois
futuros professores de Matemática no processo de elaboração de um plano de aula envolvendo a perspectiva
da Gamificação. A partir de três encontros formativos realizados por meio da plataforma Google Meet, anali-
sou-se qualitativamente, a partir componentes e indicadores de Adequação Interacional propostos pela Abor-
dagem Ontossemiotica, o plano de aula realizado pelos participantes na perspectiva gamificada. Desse modo,
considerou-se como córpus de dados as gravações dos encontros bem como os materiais produzidos pelos
participantes. A partir da análise, os dados evidenciaram que a utilização da Metodologia Gamificação fez com
que o critério de Adequação Interacional se mostrassem mais evidente, visto que essa metodologia tem como
fundamento a interação e inclusão dos alunos.The present study aims to analyze the Interactional Didactic Adequacy Criterion revealed by two future Mathe-
matics teachers in the process of elaborating a lesson plan involving the perspective of Gamification. From three
training meetings carried out through the Google Meet platform, the lesson plan carried out by the participants
in the gamified perspective was qualitatively analyzed, based on components and indicators of Interactional
Adequacy proposed by the Ontosemiotic Approach. Thus, the recordings of the meetings as well as the ma-
terials produced by the participants were considered as data corpus. From the analysis, the data showed that
the use of the Gamification Methodology made the Interactional Adequacy criterion more evident, since this
methodology is based on the interaction and inclusion of students
Bilíngues intermodais : aquisição da Língua de Sinais como L1 e da Língua Escrita como L2.
No full textBased on a bibliographical review and re-readings of different authors, we aim to bring visibility to the discussion regarding intermodal bilingualism and, consequently, to present a reflection on the acquisition of the first and second
languages (L1 and L2) by deaf children. We aim to highlight the importance of the first language, in this case, sign language, as a means for developing competence in the second language, the oral language, in its written modality. We divided the article into an explanation of the contact of deaf children with sign language (SL) as their first language. It discusses the development of oral language (OL) as the second language: first addressing writing and then moving on
to issues related to reading. Finally, it reflects on using visual resources and how these visual modes can enhance the second language teaching and learning process for deaf children.A partir de uma revisão bibliográfica, releituras de diferentes autores, intenciona-se dar visibilidade à discussão quanto ao bilinguismo intermodal e, assim, apresentar uma reflexão sobre a aquisição da primeira e segunda línguas (L1 e L2) por crianças surdas. Objetiva ecoar quanto à importância da primeira língua, nesse caso, a língua de sinais, como meio para o desenvolvimento da competência da L2, língua oral, modalidade escrita. O artigo se divide em uma explanação sobre o contato da criança surda com a língua de sinais (LS), como primeira língua e discute o desenvolvimento na língua oral (LO) como segunda língua: primeiramente, tratando da escrita e, em seguida, segue-se para questões relacionadas à leitura. Por fim, apresenta uma reflexão sobre os recursos imagéticos e como estes modos visuais podem engrandecer o processo de ensino e aprendizado de segunda língua para as crianças surdas
High depressive symptomatology reduces emotional reactions to pictures of social interaction.
No full textIndividuals with severe depressive symptoms present diminished facial expressions compared to
healthy individuals. This reduced facial expression, which occurs in most depressive patients could impair social relationships. The current study sought to investigate whether pictures with social interaction cues could elicit diferent modulations of facial expressions and mood states in individuals with depressive symptoms compared to healthy individuals. A total of 85 individuals were divided into depressive and non-depressive groups based on their beck depression inventory scores. Participants viewed pictures containing neutral (objects), afliative (people interacting socially), and control (people not interacting) scenes. Electromyographic signals were collected during the entire period of visualization of the blocks, and emotional questionnaires were evaluated after each block to assess sociability and altruism (prosocial states). In non-depressed individuals, afliative pictures increased the activity of the zygomatic muscle compared to both neutral and control pictures and reduced fear of rejection compared to neutral pictures. During the visualization of the afliative block, zygomatic major muscle activation was higher and fear of rejection was lower in the non-depressive individuals than in the depressive. These efects refected the low expressions of smiling and sociability to afliative pictures in depressive individuals. These fndings highlight the importance of smiling and prosocial states in social interactions, especially in these individuals
Assessing levels of uric acid and other cardiovascular markers in prehypertensive and hypertensive adults.
No full textIntroduction: Although some studies have reported the association between uric acid (UA) and hypertension, evidence on prehypertension is still lacking. Therefore, the objective of this study was to determine the levels of UA and other cardiovascular markers among prehypertensive and hypertensive patients and assess their risk for developing arterial hypertension.
Methods: 157 individuals were recruited: 67 normotensive, 23 pre-hypertensive and 67 hypertensive. Blood samples were collected to measure biochemical parameters and anthropometric measurements and blood pressure were evaluated. We calculated the product of lipid accumulation and the visceral adiposity index to assess cardiovascular risk.
Results: Our data showed an increase in UA levels in normotensives (4.9 ± 1.3 mg/dL), prehypertensives (5.2 ± 1.3 mg/dL) and hypertensives (5.9 ± 1.6 mg/dL) (p = 0.004). We found a higher frequency of hyperuricemia in the hypertensive group (34.3%) than in the normotensive group (13.4%, p < 0.05). Hypertensive volunteers had lower levels of HDL-C (p = 0.004 and p = 0.003) and higher body mass indexes (p < 0.001 and p = 0.007), glucose (p < 0.001 and p = 0.033), triglycerides (p = 0.001 and p = 0.005), visceral adiposity index (p < 0.001 and p = 0.002) and lipid accumulation product (p < 0.001 and p = 0.007) than normotensive and prehypertensive participants. We also observed that individuals with UA ≥ 6.2 mg/dL had an increased risk of hypertension of 4.77 (p = 0.003) compared to individuals with levels ≤ 4.3 mg/dL
Análise dos impactos nos recursos hídricos em cenários prospectivos de uso e ocupação do solo na bacia do rio do Carmo, Minas Gerais.
No full textPrograma de Pós-Graduação em Engenharia Ambiental. Núcleo de Pesquisas e Pós-Graduação em Recursos Hídricos, Universidade Federal de Ouro Preto.Este estudo investigou as mudanças futuras no uso e ocupação do solo e
seus impactos nos recursos hídricos na bacia do rio Carmo, Minas Gerais,
utilizando uma abordagem de modelos acoplados: Dinamica-EGO e SWAT. A
modelagem do Dinamica-EGO foi realizada por meio das metodologias de
matrizes de transição, pesos de evidência e autômatos celulares. A simulação
foi validada por meio da função de decaimento exponencial e múltiplas janelas,
adaptada da tradicional metodologia Fuzzy, obtendo valores de similaridade
mínima de 0,58 para uma resolução espacial de 285m. Foram simulados três
cenários futuros de uso do solo: Business as Usual (BAU), Otimista (OTM) e
Pessimista (PES), considerando os cenários climáticos RCP 4.5 e RCP 8.5 do
IPCC. A modelagem hidrológica foi calibrada utilizando o RSWAT, por meio da
metodologia de calibração que utiliza o algoritmo Sequential Uncertainty Fitting
(SUFI-2), obtendo valores de KGE 0,66 e R2 0,58. O cenário BAU projeta a
continuação das tendências históricas, com um aumento modesto na cobertura
florestal e trocas entre agricultura e pastagens. O cenário OTM indica um
crescimento expressivo nas áreas florestais devido a políticas ambientais
proativas, enquanto o PES simula um declínio nas áreas florestais, agrícolas e
de silvicultura, impulsionado pela expansão das pastagens e áreas urbanas. A
simulação hidrológica com o SWAT revelou reduções significativas nas vazões
máximas e médias, atingindo 70% e 24%, respectivamente; e aumento das
mínimas (8% a 16%), com variações entre os cenários e trajetórias climáticas
simuladas, quando comparadas com os valores atuais simulados. Destaca-se o
cenário otimista, que enfatiza práticas de gestão sustentável, e mostra um
potencial significativo para a regeneração da vegetação, expansão das
atividades de plantio florestal, e resiliência frente à escassez hídrica. As
limitações e dificuldades encontradas incluem a harmonização de dados e a
adequação dos parâmetros de calibração dos modelos, destacando a
importância de dados de alta qualidade e metodologias robustas. Esses
resultados sublinham a importância de políticas de gestão integrada para a
sustentabilidade dos recursos hídricos e do uso e ocupação do solo.
Considerando o impacto do rompimento da barragem de Fundão em 2015, que
liberou milhões de metros cúbicos de rejeitos de mineração, os achados deste
estudo são essenciais para orientar estratégias de recuperação ambiental e
fortalecer a resiliência das bacias hidrográficas afetadas por desastres. A
abordagem de modelos acoplados utilizada neste estudo oferece uma visão
abrangente das possíveis mudanças futuras, enriquecendo as discussões sobre
a gestão do território e dos recursos hídricos e a eficácia das políticas
ambientais.This study investigated future changes in land use and their impacts on
water resources in the Carmo river basin, Minas Gerais, using a coupled model
approach: Dinamica-EGO and SWAT. Dinamica-EGO modeling was carried out
using transition matrices, weights of evidence and cellular automata
methodologies. The simulation was validated using the exponential decay
function and multiple windows, adapted from the traditional Fuzzy methodology,
obtaining minimum similarity values of 0.58 for a spatial resolution of 285m. Three
future land use scenarios were simulated: Business as Usual (BAU), Optimistic
(OTM) and Pessimistic (PES), considering the IPCC's RCP 4.5 and RCP 8.5
climate pathways. The hydrological modeling was calibrated using RSWAT,
through the calibration methodology that uses the Sequential Uncertainty Fitting
(SUFI-2) algorithm, obtaining values of KGE 0.66 and R2 0.58. The BAU scenario
projects a continuation of historical trends, with a modest increase in forest cover
and shifts between agriculture and pastures. The OTM scenario indicates
significant growth in forest areas due to proactive environmental policies, while
the PES simulates a decline in forest, agricultural and forestry areas, driven by
the expansion of pastures and urban areas. The hydrological simulation with
SWAT revealed significant reductions in maximum and average flows, reaching
70% and 24%, respectively; and increase of minimum flows (8% to 16%) varying
between the scenarios and simulated climate trajectories, when compared to the
simulated current values. The optimistic scenario stands out, which emphasizes
sustainable management practices, and shows significant potential for vegetation
regeneration, expansion of forestry, and resilience in the face of water scarcity.
The limitations and difficulties encountered include data harmonization and the
adequacy of model calibration parameters, highlighting the importance of high-
quality data and robust methodologies. These results highlight the importance of
integrated management policies for the sustainability of water resources and land
use and occupation. Considering the impact of the Fundão dam-break in 2015,
which released millions of cubic meters of mining waste into the environment, the
findings of this study are essential to guide environmental recovery strategies and
strengthen the resilience of river basins affected by disasters. The coupled model
approach used in this study offers a comprehensive view of possible future
changes, enriching discussions about territorial and water resources
management and the effectiveness of environmental policies
“Welcome to Montero” : as performances de masculinidade negra nos videoclipes de Lil NasX.
No full textPrograma de Pós-Graduação em Comunicação. Instituto de Ciências Sociais Aplicadas, Universidade Federal de Ouro Preto.Lil Nas X é um rapper norte-americano negro e homossexual. Seu primeiro álbum de estúdio,
intitulado Montero, se refere ao seu nome real. Por ser um álbum mais íntimo, o artista
manifesta de maneira evidente os atravessamentos identitários que perpassam por seu corpo.
Tendo em vista isso, são analisados três videoclipes (INDUSTRY BABY, MONTERO (Call
Me By Your Name) e THATS WHAT I WANT) que apresentam uma narrativa visual e musical
única, se conectando com a identidade performática do artista e com seu posicionamento
político. Partindo do viés interseccional (CARRERA, 2021; HOOKS, 2019; ANZALDÚA,
2005; CRENSHAW, 2002), ou seja, da perspectiva de cruzamentos identitários, é possível
identificar na performance (TAYLOR, 2013; SOARES, 2014; AMARAL, SOARES e
POLIVANOV, 2018; GUTMANN e FILHO, 2019; GUTMANN e MOTA JUNIOR, 2020) de
Lil Nas X, a negociação de múltiplas formas de pensar masculinidades negras (HALL, 1992;
FAUSTINO, 2014; CONRADO e RIBEIRO, 2017; HAWKINS, 2017; HOOKS, 2019;
RIBEIRO, 2020; PORFÍRIO, 2021; COSTA, 2023) na Cultura Pop. Em modos mais práticos,
busca por reconhecer os rastros de interseccionalidade, ou melhor, o sujeito que se constrói, na
performance em videoclipe (GUTMANN e MOTA JUNIOR, 2020; SOARES, 2014) do Lil
Nas X. Neste sentido, é acionado a Roleta Interseccional (CARRERA, 2021) como operador
analítico para a identificar os rastros de desvios e repetições de intersecções mobilizadas pelo
sujeito pesquisado. Tendo essas questões em vista, é elaborada uma tabela, dividida em quatro
eixos principais (INSTITUIÇÃO DISCIPLINAR, CONTEXTO, TRANSGRESSÃO e
CONDENAÇÃO), que auxilia a compreender a construção de narrativa dos videoclipes e,
consequentemente, os discursos, simbologias e metáfora mobilizados. Logo, por meio da tabela,
se faz possível reconhecer, analisar e nomear as temáticas materializadas pelo artista que
perpassam pela ideia de SABER-PRAZER, HOMOEROTISMO e AFETIVIDADE NEGRA.
Por meio desses eixos temáticos analisadas, é perceptível uma performance multifacetada que
tensiona e desestabiliza as marcas normativas de masculinidade negra.Lil Nas X is a black, homosexual American rapper. His first studio album, titled "Montero," is
a reference to his real name. As a more intimate album, the artist overtly expresses the
intersecting aspects of his identity that traverse his body. In light of this, three music videos
(INDUSTRY BABY, MONTERO (Call Me By Your Name), and THAT'S WHAT I WANT)
are analyzed, presenting a unique visual and musical narrative that connects with the artist's
performative identity and political stance. Taking an intersectional perspective (CARRERA,
2021; HOOKS, 2019; ANZALDÚA, 2005; CRENSHAW, 2002), i.e., considering the
intersections of identity, it is possible to identify in Lil Nas X's performance (TAYLOR, 2013;
SOARES, 2014; AMARAL, SOARES, and POLIVANOV, 2018; GUTMANN and FILHO,
2019; GUTMANN and MOTA JUNIOR, 2020) the negotiation of multiple ways of
conceptualizing black masculinities in popular culture (HALL, 1992; FAUSTINO, 2014;
CONRADO and RIBEIRO, 2017; HAWKINS, 2017; HOOKS, 2019; RIBEIRO, 2020;
PORFÍRIO, 2021; COSTA, 2023). In more practical terms, this research seeks to recognize
traces of intersectionality or the construction of the subject in Lil Nas X's music video
performance (GUTMANN and MOTA JUNIOR, 2020; SOARES, 2014). In this regard, the
Intersectional Roulette (CARRERA, 2021) is employed as an analytical tool to identify traces
of deviations and repetitions of intersections mobilized by the researched subject. Considering
these issues, a table is constructed, divided into four main axes (DISCIPLINARY
INSTITUTION, CONTEXT, TRANSGRESSION, and CONDEMNATION), which helps to
understand the narrative construction of the music videos and, consequently, the discourses,
symbols, and metaphors mobilized. Thus, through the table, it becomes possible to recognize,
analyze, and name the themes materialized by the artist that revolve around the idea of
KNOWLEDGE-PLEASURE, HOMOEROTICISM, and BLACK AFFECTION. Through
these thematic axes analyzed, a multifaceted performance is perceptible that tensions and
destabilizes the normative brands of black masculinity
Death feigning in ants.
No full textIn many animals, feigning death is a last resort to avoid being killed by a predator or competitor. While the neurological and physiological correlates of death feigning (DF) as well as its adaptive significance have intensively been studied in numerous arthropods, detailed studies on this phenomenon in ants are rare. Here, we describe DF in ants in detail and show that in many species it can be provoked by experimental manipulation or staged encounters with aggressive competitors in the laboratory. Much less is known about the context and consequence of death feigning in nature and whether it successfully protects ants from ant-eating predators or territorial intruders. We suggest additional research on this often neglected, but easily studied phenomenon, which will help to increase our understanding of its importance and underlying causes
“Documentos falsos” : a metaficção historiográfica suas possibilidades e contribuições à historiografia.
No full textPrograma de Pós-Graduação em História. Departamento de História, Instituto de Ciências Humanas e Sociais, Universidade Federal de Ouro Preto.Esta pesquisa se filia ao ramo da teoria da história que investiga a relação entre literatura e
história e suas mútuas contribuições. Analisando metaficções historiográficas publicadas por
autores de língua inglesa entre os anos 1969 e 1975, ela também espera contribuir para as
pesquisas sobre a pós-modernidade e sua poética. As obras estudadas constituem um grupo bem
definido, dentro do universo bastante diverso das metaficções historiográficas publicadas na
segunda metade do século XX, e apresentam uma relação semelhante com a referencialidade.
Investigamos a hipótese de que elas sejam capazes de aproximar seus leitores de questões caras
à escrita da história e que além disso, contenham indicativos da historicidade de seu próprio
tempo. Nossa pesquisa aponta que mesmo os autores de orientação marxista se dedicaram às
questões ligadas ao giro linguístico e, através de obras com formatos de grande alcance de
público, levaram aos leitores reflexões sobre a construção do discurso de passado, sua
localidade e a existência de passados silenciados nessa construção. Publicadas em um período
marcado pela grande difusão das ideias do giro linguístico, as obras abordam a dimensão
narrativa do passado, tanto na sua forma de acesso, quanto na sua representação. Além disso,
as metaficções historiográficas analisadas se mostraram um documento de seu próprio tempo,
refletindo seus temas, suas abordagens e permitindo considerações sobre a sua historicidade.This research is affiliated with the branch of history theory that investigates the relationship
between literature and history and their mutual contributions. By analysing historiographical
metafictions published by English-language authors between 1969 and 1975, it also hopes to
contribute to research on postmodernity and its poetics. The works studied constitute a well-
defined group, within the very different universe of historiographical metafictions published in
the second half of the 20th century and present a similar relationship with referentiality. We
investigated the hypothesis that they are capable of bringing their readers closer to issues
important to the writing of history and that, in addition, they contain indications of the
historicity of their own time. Our research shows that even authors with a Marxist orientation
dedicated themselves to issues linked to the linguistic turn and, through works with formats
with a wide audience reach, they brought to readers reflections on the construction of the
discourse of the past, its locality and the existence of pasts silenced by such construction.
Published in a period marked by the great diffusion of the ideas of the linguistic turn, the works
address the narrative dimension of the past, both in its form of access and in its representation.
Furthermore, the historiographical metafictions analysed proved to be a document of their own
time, reflecting their themes, their approaches and allowing considerations about their
historicity
