Keyakinan seseorang akan kemampuannya untuk mencapai tujuan (Self efficacy)  diperlukan siswa untuk dapat  menghadapi Ujian Nasional (UN) dengan baik. Penelitian ini bertujuan untuk mengetahui hubungan self efficacy dengan kecemasan dalam menghadapi ujian nasional. Jenis penelitian ini adalah penelitian kuantitatif. Subjek dalam penelitian ini 70 siswa SMK kelas 3. Metode pengumpulan data adalah skala, dengan skala likert. Metode analisa data adalah korelasi product moment. Hasil penelitian menunjukkan koefisien korelasi (r) sebesar -0,615dan (p) = 0,000 hal ini menandakan adanya hubungan negatif yang sangat signifikan antara variabel self efficacy dengan variabel kecemasan. Hal ini berarti apabila self efficacy tinggi maka kecemasan menghadapi ujian nasional rendah, dan sebaliknya jika nilai self efficacy rendah maka kecemasan dalam menghadapi ujian nasional tinggi. Nilai koefisien determinan ( ) = 0,378, yang bermakna bahwa variabel self efficacy mampu menjelaskan variabel kecemasan menghadapi ujian nasional sebesar 37,8%, sisanya sebesar 62,2% dipengaruhi oleh variabel lain. Kata kunci: Self efficacy, Kecemasan a person's belief in his/her ability to achieve the goals is need student to convince the students could face the national examination well because students sometime get an anxiety in facing the national examinations. Otherwise, if the students have high self-efficacy then the students will have low anxiety because those students are already convinced of their ability. The purpose of this study is to determine the relationship of self-efficacy with the anxiety of facing national examinations. The type of this research is quantitative research. The populations in this study are the students of 3rd grade of vocational school. The methods of collecting the data is scale, by using Likert scale. While the method of data analysis used product moment correlation..Based on the data analysis, it obtained that the correlation of coefficient (r) is -0.615 and (p) = 0.000 it indicates that there is a relationship of negative direction which very significant between self-efficacy variable with the anxiety variable. This means if the self-efficacy is high so the anxiety of facing national exams is low and the vice versa if the value of self-efficacy is low, the anxiety of facing national exam is high. The value of determinant coefficient (R2) = 0.378, which means that the self-efficacy variable could explain the anxiety variable of facing national exams at 37.8%, the other is 62.2% influenced by other.

Kecemasan merupakan suatu emosi yang paling sering di alami oleh manusia. Kecemasan dapat disebabkan banyak hal salah satunya adalah terpenuhi tidaknya kebutuhan dasar. Tujuan dari penelitian ini adalah untuk mengetahui kebutuhan apa saja yang belum terpenuhi dan bagaimana kebutuhan tersebut dapat menyebabkan kecemasan.Penelitian ini menggunakan metode penelitian kualitatif dengan menggunakan metode pengumpulan data yaitu, wawancara dan observasi. Subjek dalam penelitian ini berjumlah lima orang, dengan kriteria memiliki tingkat kecemasan tinggi (dengan skor >20 berdasarkan kategori TMAS). Berdasarkan hasil penelitian dapat disimpulkan bahwa dalam diri setiap subjek masih terdapat kebutuhan-kebutuhan dasar yang belum terpenuhi. Terdapat persamaan pada setiap subjek yaitu kebutuhan dasar dari seluruh subjek yang belum terpenuhi adalah safety needs. Kecemasan yang terjadi akibat dari safety needs, karena adanya perasaan takut akan hukuman yang akan diperoleh dari sosok otoriter yang berada dilingkungan subjek, dan perasaan takut akibat ditinggal sendirian. Kegagalan akan pemenuhan safety needs pada masing-masing subjek berasal dari lingkungan terdekat subjek sejak kecil. Seperti orangtua, keluarga sekitar, guru serta teman-teman sepermainan.   Kata kunci: Kecemasan, Kebutuhan dasar   Anxiety represent the most frequently emotion experienced by human being. Anxiety  can be caused by many matter, on of causes its requirement well or no fulfilled of basic needs. Based on the problems, this research intention is to know any kind of basic needs  which not yet fulfilled and how the basic needs requirement can caused anxiety.This research use qualitative research method by using collecting data method which is, observation and interview. Subject in this research amount to five people, with criterion have high anxiety level ( with score > 20 based on TMAS category).Based on this research result, it can be concluded that inside every subject there are some basic needs requirement which not yet fufilled. There are similarity in each subject that basic needs requirement from entire subject which not yet fulfilled is safety needs. Anxiety that happened as the effect of unfulfilled  safety needs, caused by feeling in fear of punishment  to be obtained from authoritarian figure which reside in subject’s environment, and feeling fear effect remained alone. This Failure of accomplishment of safety needs at each subject sourced from the closest environment subject since childhood.

La desnutrición infantil es un problema actual multicausal y con consecuencias graves en la salud individual y pública a nivel mundial. Los niños preescolares de zonas, rurales son el grupo más vulnerable; sin embargo, no existen investigaciones enfocadas en microrregiones que aporten información veraz sobre su estado nutricional y las causas subyacentes. El objetivo de este estudio, fue determinar la prevalencia de desnutrición infantil en Tochimilco, Puebla, y precisar los determinantes que influyen en el estado nutricional, tanto internos como externos. Se realizó una evaluación nutricional con antropometría, historia clínica y dietética a 61 preescolares; se aplicó un cuestionario semiestructurado a 38 niños de esta población, para analizar variables sociales y ambientales con estadística descriptiva y multivariada. Se encontró que 51% se encuentran en riesgo de desnutrición, 48% presentan déficit de talla/edad y 35% padece bajo peso. Además, el tipo de localidad rural/urbana influyó en el estado nutricional; el apoyo gubernamental, también se asoció con el peso/talla y peso/ edad, especialmente el programa de becas. Los patrones de alimentación, aportan energía y macronutrimentos suficientes, pero de muy mala calidad. En conclusión, la población infantil de Tochimilco está en riesgo de desnutrición mayor al reportado y la estrategia más eficiente para erradicarla, no sólo es mejorar las condiciones de vida y carencias sociales, sino incluir el componente de educación para la alimentación.

Se concluyó que el SPo, tiene mayor tendencia hacia un manejo sustentable, lo cual resalta la importancia de revalorizar este tipo de agroecosistemas, cuyo potencial productivo fortalece la soberanía alimentaria.
A VIOLÊNCIA OBSTÉTRICA CONTRA A MULHER SOB A PERSPECTIVA TEÓRICA INTERSECCIONAL: Uma revisão narrativa
Authors: Alves Maria Alice , Alves Diego Ramon
Published: March 2024

This study aims to reflect obstetric violence against women from the theoretical perspective of intersectionality. This is a narrative review that was proposed to analyze from the national literature, available in the databases: SciELO, ARCA and VHL, research that addressed the central theme of the present study and in each database the health descriptors were used: "intersectional theory", "obstetric violence" and "gender and ethnic racism" organized by the Boolean operator “AND”. From the extensive literature we can infer that obstetric violence against women occurs mainly against black, brown, indigenous and poor women, that is, women who most accumulate intersections/social determinants of health. Finally, obstetric violence does not choose a profile, all people who are pregnant are subject to being violated just because of their ability to conceive and undergo obstetric procedures. However, it can worsen depending on your environment, class, race, gender, sexual orientation, religion, ethnicity and other intersections.
AMPLIANDO HORIZONTES: Integração de saberes para além do consultório psicológico
Authors: Pires Sergio Fernandes Senna
Published: March 2024

In this theoretical essay, we explore the imperative to reposition Clinical Psychology, emphasizing the challenges it faces due to limitations imposed by biases that restrict the utilization of its knowledge to conventional therapeutic settings. We contemplate the necessity to, at least partially, overcome the fragmentation of psychological knowledge to foster the emergence of more integrative approaches. We underscore the resistance that emerges from the broad association of Clinical Psychology with the medical model or the dichotomy of health versus disease. To address this misconception, we stress the importance of integratively linking knowledge constructed across various fields of Psychology. Examples are provided to illustrate the imperative use of innovative strategies in integrating transversal and heterodox approaches, incorporating contributions from Clinical Psychology. The application of adaptable clinical techniques for unconventional contexts, such as utilizing Psychodrama in socio-emotional education, underscores the relevance of this adaptation in addressing issues like violence and the deconstruction of prejudices. In conclusion, the promotion of a more integrative Psychology proves essential for delving deeper into knowledge and devising solutions for complex problems. By challenging prejudices and expanding the application scope of practical-scientific knowledge derived from Clinical Psychology, we highlight its potential contribution to constructing a more comprehensive understanding of the human experience.

POLYMER-BASED IONIC CONDUCTORS
Authors: Mohd Arof Abdul Kariem
Published: March 2024

Polymer electrolytes consist of polymer matrices with ion transport capabilities and can exist in either a solid or gel state. In both states, the incorporation of plasticizers and fillers will improve the ionic conductivity. Gel polymer electrolytes (GPEs) exhibit ionic conductivity levels remarkably akin to those of liquid electrolytes, owing to the direct solvation of salts within solid polymer electrolytes.

Published: March 2024

Objective: To describe the microbiome of the vagina and fallopian tubes,
and its relation with hydrosalpinx. Design: Prospective case-control
study. Population and Settings: Women who underwent salpingectomy for
hydrosalpinx or other indications at our medical center . Main Outcome
Measures: Samples obtained during surgery and were subjected to 16S rRNA
amplicon sequencing, and analyses of alpha diversity and beta diversity
meseaures were compared between sites and groups. Differential
abundances of bacteria associated with vaginal dysbiosis was compared
between cases and controls. Results: Nine women with hydrosalipnx, and
23 women without hydrosalpinx were included in the study. The mean age
of studied women was 41 (range: 29-54), and most (89%) were
premenopausal. After in silico decontamination, only 30% of control
fallopian tubes samples, and 10% of case fallopian tubes samples, had
evidence of bacterial presence. The vaginal microbiota of control
patients showed greater abundance of lactobacilli whereas the vaginal
microbiome of case patients contained relatively more bacterial
vaginosis associated bacteria such as Prevotella,
Gardenrella and Atopobium. A significant difference was
found in alpha and beta diversity between the vaginal and FT microbiomes
in control patients, as fallopian tubes samples were more diverse. We
found that women with hydrosalpinx had a more “dysbiotic” vaginal
microbiome, and in women without hydrosalpinx, microbial composition
within the vagina and FT differed, possibly representing two distinct
ecological environments. Conclusion: women undergoing salpingectomy for
various reasons harbored bacteria within their FT, women with
hydrosalpinx generally did not. This suggests that even though infection
may be an underlying cause of hydrosalpinx, bacteria may not be present
by the time patients require surgery.
Discovery platforms for RNA therapeutics

Published: March 2024

RNA therapeutics are emerging as a unique opportunity to drug currently
“undruggable” molecules and diseases. While their advantages over
conventional, small molecule drugs, their therapeutic implications and
the tools for their effective in vivo delivery have been extensively
reviewed, little attention has been so far paid to the technological
platforms exploited for the discovery of RNA therapeutics. Here, we
provide an overview of the existing platforms and ex vivo assays for RNA
discovery, their advantages and disadvantages, as well as their main
fields of application, with specific focus on RNA therapies that have
reached either phase 3 or market approval.
Seed morphology of Astragalus (Fabaceae, Astragaleae) and its systematic implication: an effort towards a standard terminology
Authors: ZARRE SHAHIN , DARZI RAHELEH , MAASOUMI ALI ASGHAR , SHAHROKH KAZEMPOUR-OSALOO
Published: March 2024

In big plant genera such as Astragalus (Fabaceae), the evaluation
of morphological evidence from reliable resources is a prerequisite for
understanding the evolutionary history, relationships, and taxonomic
placements. The present study is the most comprehensive effort to assess
the seed morphological characters in a large sample of species. Seed
characteristics including size, color, shape, and testa ornamentation of
494 seed samples representing 348 species and 83 sections and all 11
main clades recognized in Astragalus and five species of related
genera were investigated using light and Scanning Electron Microscopy.
We provide here a standard terminology for all examined characters to
suggest a consensus for future seed morphological studies. Accordingly,
seed morphological features show considerable variability, making them
useful in some taxonomic aspects, but they may also be heterogeneous,
which sometimes limits their application. Based on our results none of
the natural groups known as section or clades in Astragalus can
be defined based on one character, but rather using a combination of
distinctive character states. Considering the currently available
phylogenetic trees of Astragalus, the present seed morphological
survey allows us to suggest some evolutionary trends. In the course of
evolution in most clades, the seed size tends to reduce, reddish seeds
tend to be frequent over other colors, black dots or spots appear or
distribute more densely on the surface, oblong and square as well as
semi-oblong-elliptic shapes become abundant, the pit-like depressions on
the seed surface tend to increase, and the multiple reticulate-rugulate
testa ornamentation appears more frequently.
Molecular and structural evidence of the toxic effects of garlic and Citrullus colocynthis individually and in combination on the testis of male rats
Authors: Gol Ali , Mohammadzadeh Aghileh
Published: March 2024

Garlic and Citrullus colocynthis are medicinal plants that are
widely used in herbal medicine. However, as they may be used as
preventives for some diseases, they may represent side effects. However,
their side effects on male reproduction have rarely been studied. The
purpose of this study is to investigate the toxic effects and possible
mechanism of consuming garlic and Citrullus colocynthis
separately and in combination for 1 month on the testicles of normal
rats. Twenty-eight male Wistar rats were divided into 4 groups (n=7): 1.
Control; 2. Garlic, which received 1 ml/100 g of bw of garlic extract;
3. C. colocynthis, which received 10 mg/kg of bw of C.
colocynthis; 4. Garlic+ C. colocynthis, which received 1 ml/100
g of bw of garlic extract and 10 mg/kg of bw of C. colocynthis.
After 30-days of experiment, body & testis weight, endogenous hormone
levels and sperm count were determined. In addition, apoptosis and
oxidative stress markers were identified. The results showed that the
administration of garlic and C. colocynthis separately and in
combination decreased testis weight, sperm count and the level of
testosterone and luteinizing hormones in rats. In addition, oxidative
stress markers, expression of mRNAs for NADPH oxidase-4 (Nox-4) and
nuclear factor kappa B (NF-κB), and of caspase-3 immunoexpression were
all increased in the testis. It seems that consuming garlic and C.
colocynthis separately and in combination for 1 month causes testicular
injury in rats and dosage of usage should be taken into account for
preventive purposes.

Ablation Catheter Entrapment in the Mitral Valve Apparatus During Ablation of Premature Ventricular Complexes
Authors: Wang Fan , Yang Qian , Li Xinning , Zhang Feifei , Song Xuelian , Dang Yi
Published: March 2024

Entrapment of the ablation catheter in the mitral valve apparatus during
transaortic ablation of premature ventricular complexes is a rare
complication that usually requires surgical removal. Random rotating and
pulling of the catheter exacerbate the extent of the entrapment, causing
chest pain and a drop in blood pressure. The catheter can be loosened by
changing the direction of the vector at the tip of the catheter, pulling
in the reverse direction and rotating. We describe the case of the
thought process and catheter maneuvers used to diagnose, loosen, and
remove a trapped catheter.
Near-Automated Estimate of City Nitrogen Oxides Emissions Applied to South and Southeast Asia
Authors: Lu Gongda , Marais Eloise Ann , Vohra Karn , Horner Rebekah P , Zhang Dandan , Martin Randall V , Guttikunda Sarath K
Published: March 2024

Cities in South and Southeast Asia are developing rapidly without
routine, up-to-date knowledge of air pollutant precursor emissions. This
data deficit can potentially be addressed for nitrogen oxides
(NO) by deriving city NO emissions
from satellite observations of nitrogen dioxide (NO)
sampled under windy conditions. NO plumes of isolated
cities are aligned along a consistent wind-rotated direction and a
best-fit Gaussian is applied to estimate emissions. This approach
currently relies on non-standardized selection of the area to sample
around the city centre and Gaussian fits often fail or yield
non-physical parameters. Here, we automate this approach by defining
many (54) sampling areas that we test with TROPOspheric Monitoring
Instrument (TROPOMI) NO observations for 2019 over 19
cities in South and Southeast Asia. Our approach is efficient, adaptable
to many cities, standardizes and eliminates sensitivity of the Gaussian
fit to sampling area choice, and increases success of deriving annual
emissions from 40-60% with one sampling area to 100% (all 19 cities)
with 54. The annual emissions we estimate range from 16±5 mol
s for Yangon (Myanmar) and Bangalore (India) to
125±41 mol s for Dhaka (Bangladesh). With the
enhanced success of our approach, we find evidence from comparison of
our top-down emissions to past studies and to inventory estimates that
the wind rotation and EMG fit approach may be biased, as it does not
adequately account for spatial and seasonal variability in
NO photochemistry. Further methodological development
is needed to enhance its accuracy and to exploit it to derive sub-annual
emissions.
Emission Taxes and Capital Investments: The Role of Tax Incidence
Authors: Jacob Martin , Zerwer Kira Lena
Published: March 2024

This paper examines investment responses to emission taxes and the role of tax incidence in passing on tax burdens. Using private firms from Spain and the introduction of an emission tax in 2013 in the Autonomous Community Valenciana, we show that investments decline in response to the emission tax. Importantly, this investment decline does not depend on the level of pollution but on economic factors related to tax incidence. Investments in firms operating in highly competitive markets, firms with low pricing power, and firms with low financial flexibility are the most affected by environmental taxes. We generalize the investment findings using the introduction of carbon taxes in France and Ireland in a stacked difference-in-differences design. Overall, our results indicate that emission taxes affect not only polluters but also other firms and stakeholders such as suppliers, customers, and consumers depending on the relative elasticities of supply and demand.

Novel Test Techniques to Characterise the Mechanical Performance of Additive Manufactured (AM) Aerospace Alloys
Authors:   , Haigh Benjamin
Published: March 2024

With the continuous evolution of the aerospace industry, there is a strong desire to fabricate more intricate components in the modern jet engine that exhibit less stress-raising features to enable higher engine efficiencies to be achieved. To achieve this goal, aerospace engineers are looking at additive manufacturing (AM) as a potential solution since AM provides a manufacturing technique that uses less raw material in the form of a powder, saving material which in turn reduces the cost of the process. One of the major limitations of AM is the resulting transient nature of the microstructure typically produced by the process, and it is difficult to fabricate representative laboratory scale mechanical test specimens that closely replicate the microstructure of the finished component. Therefore, it can be beneficial to utilise more novel small-scale test methods, such as the small punch (SP) test and shear punch (ShP) test, which can obtain mechanical property information from miniaturised specimens extracted directly from the finished part. In this research programme, correlations have been made between standard conventional testing techniques and the novel small-scale methods to investigate the suitability of using such methods in characterising the mechanical properties of laser powder bed fused (LPBF) aerospace materials, namely the nickel based polycrystalline superalloy, Inconel 718, and the titanium alloy, Ti-6Al-4V specimens. Furthermore, effort will be directed towards identifying whether small scale test methods can effectively establish whether the mechanical response of additively manufactured components vary within a single build, or likewise, across different builds, which could provide a key insight for design engineers both now and in the future.

Published: March 2024

The current research was conducted during May–October, 2023 aimed to assess the haemato-biochemical parameters in cattle affected with S. aureus affected subclinical mastitis. Mastitis in dairy cattle is the persistent, inflammatory reaction of the udder tissue. Financial losses due to mastitis occur in the case of both sub-clinically and clinically affected animals. Sub-clinical mastitis exhibits no clinical signs and mostly remains unnoticed by the farmer and can be detected if specific tests are performed in milk samples. Sub-clinical mastitis has an erosive effect on the economy of dairy farmers as it effect directly on the milk quality and quantity. In India prevalence of sub-clinical mastitis was found to be more in cows when compared to clinical mastitis. Blood samples were collected from the jugular vein of 10 healthy and 10 subclinical mastitis affected cattle. Blood samples were analyzed for Hb, PCV, TEC, TLC, while serum samples were examined for ALT, AST, ALP, Glucose, Total protein, Albumin, Cholesterol and Calcium. Haematology report showed significantly (p<0.01) decrease in Hb, PCV and TEC in subclinical affected cattle when compared to healthy animals. TLC was significantly increased in (p<0.01) subclinical affected animal than healthy animal. Biochemical estimate revealed significantly (p<0.05) higher average values of AST, ALP and Ca in subclinical mastitis affected animals compared to healthy animals. Glucose, total protein, albumin, cholesterol and ALT levels are significantly (p<0.05) decrease in subclinical mastitis affected animals when compared to healthy cows. Haemato-biochemical parameters can be used as important for pathological state of subclinical mastitis animals.
espiritualidade nas constelações familiares e seus reflexos para a mediação de conflitos no poder judiciário
Authors: Cavalcanti Ana Paula Rodrigues , Cahú Marlene
Published: March 2024

A abordagem fenomenológica da constelação familiar, desenvolvida pelo filósofo e terapeuta Bert Hellinger, foi introduzida no judiciário brasileiro pelo juiz Sami Storch em 2012, humanizando as práticas de conciliações e mediações de conflitos entre os litigantes. Por meio de suas experiências empíricas, Hellinger verificou que os mais variados problemas enfrentados pelos indivíduos são partilhados pelo inconsciente familiar e transmitidos às gerações seguintes. Esta pesquisa objetivou compreender a noção de campo na prática da constelação sistêmica familiar realizada no poder judiciário, e verificar se haveria correlação com o conceito de espiritualidade de Hanegraaff, numa perspectiva da ciência da religião. Foram realizadas entrevistas semiestruturadas com advogados, magistrados, promotores de justiça e servidores do poder judiciário – todos consteladores. Os dados das entrevistas foram analisados pelo software Iramuteq. Constatou-se que, para os consteladores, ocorre durante a dinâmica da constelação familiar uma transformação espiritual (ou vivência emocional mais profunda do que aquela convencional), e verificou-se estatisticamente que a espiritualidade é por eles reconhecida de forma independente, diferenciada, porém influente em toda a dinâmica da constelação familiar; isto corroborou a correlação sustentada entre o que acontece no estabelecimento do campo e a admissão da influência da espiritualidade nesta dinâmica.

O presente artigo tem como objetivo descrever e problematizar as primeiras apresentações de três vídeos da Fase 1 do projeto MathLibras em uma turma de estudantes surdos do 3º ano do ensino fundamental, em uma escola bilíngue de surdos em 2022, localizada no RS. Cada vídeo apresenta, em Libras, uma narrativa que propõe um desafio matemático relacionado ao campo aditivo, a partir de problemas de composição. A metodologia, de caráter qualitativo, contou com a apresentação de três vídeos em dois encontros, nos quais estavam os alunos surdos, uma coordenadora da escola e a equipe do MathLibras. Os dados foram produzidos a partir da filmagem das apresentações e dos materiais produzidos pelos alunos. Para a análise dos vídeos, foram selecionadas algumas cenas consideradas como eventos críticos pela equipe, nos quais os alunos manifestaram seu entendimento para o desafio proposto. Como resultados, destaca-se a percepção de equívocos visuais na hora da edição das imagens, o que gerou uma interpretação confusa por parte dos alunos. Uma das professoras precisou explicar e escrever o cálculo no quadro para que os alunos compreendessem o enunciado proposto no vídeo. Com as explicações e exemplificações escritas no quadro, os alunos resolveram de forma independente o desafio proposto no terceiro vídeo. A avaliação da recepção também destacou que aos atores precisam sinalizar a Libras de forma mais lenta, visando o público infantil.

Este artigo tem como objetivo apresentar como um aluno cego congênito pode realizar a leitura tátil de algumas representações de um gráfico de setores acessíveis. O gráfico apresentado neste trabalho foi retirado de um livro didático de matemática em tinta e representado por meio de grafo-táteis produzidos pelo programa Braille Fácil, pelo software MONET e artesanalmente utilizando diferentes artefatos materiais, tais como EVA, cubinhos do material dourado e diversos tipos de texturas. Este estudo se baseou em trabalhos e pesquisas relacionados às representações gráficas estatísticas e à confecção de materiais acessíveis para alunos cegos e com baixa visão, em especial, grafo-táteis. A metodologia utilizada neste artigo tem caráter qualitativo e foram utilizadas  técnicas de entrevistas baseadas em tarefas. Por meio deste instrumento metodológico, descrevem-se o perfil do entrevistado e a maneira como ele realizou a leitura tátil das representações gráficas apresentadas. Nos resultados obtidos, percebeu-se que a interpretação de um gráfico não é aprendida espontaneamente; segue em etapas para que o aluno possa processar as informações de modo a conectá-las e adquirir um conhecimento que seja significativo para ele.
Abordagem exploratório-investigativa em matemática para incluir crianças e jovens em situação de fracasso escolar
Authors: Cristovão Eliane Matesco , Fiorentini Dario
Published: March 2024

Este artigo pretende ressaltar, à luz das discussões sobre equidade e inclusão em educação matemática, a atualidade dos resultados de uma pesquisa concluída em 2007. Esta pesquisa, de abordagem qualitativa, buscou investigar possibilidades e contribuições da abordagem exploratório-investigativa para a aprendizagem matemática de alunos participantes de um projeto de recuperação, sobretudo para compreender e enfrentar o problema do fracasso escolar. Este projeto de recuperação integrava o regime de Progressão Continuada da rede pública de ensino do estado de São Paulo, adotado atualmente por outros estados, o que torna esta discussão ainda relevante. Os dados analisados foram coletados em uma classe que equivale ao atual 9º ano do ensino fundamental (14-15). Os referenciais analíticos da pesquisa são oriundos dos campos da educação, da educação matemática e da antropologia. A revisitação deste estudo permitiu evidenciar que a abordagem exploratório-investigativa pode favorecer a emancipação e a inclusão escolar de alunos, constituindo-se como uma forma de ressignificar o fracasso escolar e de enfrentar um sistema que visa manter a barbárie.
“Eu sei fazer na prática, mas não sei fazer na gramática”

Published: March 2024

Este artigo é resultado de um estudo com idosos matriculados em uma turma de alfabetização pertencente à Educação de Jovens e Adultos (EJA) da cidade de Uberaba - MG. O principal objetivo foi conhecer os motivos de afastamento e retorno ao contexto escolar desses alfabetizandos e evidenciar os diferentes saberes matemáticos manifestados por eles durante a pesquisa. Para tanto, foi desenvolvido um estudo empírico, de natureza qualitativa, cujas principais ferramentas de produção de dados foram observações participantes e entrevistas semiestruturadas. Tanto os registros presentes no diário de campo, quanto os enunciados dos sujeitos da pesquisa foram objetos de análise deste estudo. Os resultados indicam que esses sujeitos não vivenciaram processos de escolarização anteriormente por uma convergência de inúmeros fatores, cujo principal residiu na ausência de um sistema educacional que assegurasse seu direito à educação, e atualmente, na busca pela efetivação desse direito, eles retornam com a variedade de saberes matemáticos produzidos e mobilizados por meio de suas práticas sociais em situações diversas. Concluímos destacando a necessidade de se avançar com novas práticas pedagógicas nas quais esses diferentes saberes matemáticos sejam foco de discussão.
“Da cerveja, cês não quer tirar a validade não?”

O objetivo deste artigo é focalizar mulheres idosas alfabetizandas na Educação de Pessoas Jovens Adultas e Idosas (EJA), apropriando-se de práticas matemáticas hegemônicas, a que chamamos práticas de numeramento para destacar sua natureza discursiva. Analisamos a participação dessas mulheres nas interações discursivas durante uma atividade escolar proposta pela professora e desenvolvida dentro de um supermercado, que incluía fazer a leitura de prazos de validade de produtos industrializados. Essas interações, por sua dimensão histórica e por envolverem práticas matemáticas, são identificadas como eventos de numeramento. A atividade foi registrada em áudio, vídeo e apontamentos em diário de campo, e as interações foram cuidadosamente transcritas a partir desses registros. Nossa reflexão assume as contribuições teóricas dos estudos sobre envelhecimento, letramento e numeramento, apropriação de práticas sociais e constituição do sujeito e implica uma análise social do discurso. Nesta análise, tensionamos perspectivas sobre os processos de envelhecimento feminino e a produção de significados nas ações sociais que as alfabetizandas protagonizam quando se posicionam discursivamente e elaboram uma compreensão de como funciona o sistema de datação e dos significados semânticos e pragmáticos do registro de prazos de validade nas embalagens de produtos postos à venda. Assim, consideramos essa apropriação como instância de expressão dessas mulheres – e de sua continuada constituição – como sujeitos de aprendizagens e conhecimentos; de vivências e culturas; de memórias e esquecimentos; de direitos e expectativas.
Mulheres indígenas, agentes de mudança
Authors: Caetano Kati
Published: March 2024

Nossa reflexão a respeito de mudança articula duas frentes imbricadas de análise : o regime de ações e o regime de mudanças. Conjugamos essa perspectiva teórica a um empírico, o do movimento de indígenas mulheres brasileiras, mediante um levantamento não exaustivo de ações geradoas de transformações, visando à subjetivação e emancipação políticas. Pelo menos duas mudanças radicais podem ser identificadas como regimes estruturantes de novas formas de vida, uma vez que ao serem implementadas promulgam a legitimação das práticas como se já instituídas. Tais alterações capilarizam-se por meio de interações presenciais ou virtuais, reafirmando a existência de um actante coletivo composto por vida plurais e experienciando espaços-tempos heterogêneos da transição, mas conjugados pelo sentimento de comunalidade nos modos de presença no mundo.
Muri che diventano murales. Il “noi” del cambiamento
Authors: Migliore Tiziana
Published: March 2024

L’indagine del rapporto tra muro e murales permette di osservare da vicino le dinamiche della politica nel mondo odierno globalizzato e di individuare alcune chiavi, teoriche e metodologiche, per gli studi semiotici sul cambiamento. Un’epidemia di muri è la langue / parole e la norma dei governi di oggi, che non sanno e non vogliono fissare frontiere per gestire i territori e amministrare soggetti in mobilità. A queste separazioni autoritarie e intimidatorie la “massa parlante” risponde trasformando il muro in murales. Scritture e interventi artistici mutano le istanze di enunciazione, le prospettive e le focalizzazioni del muro : la barriera dell’Uno al potere diventa supporto di un discorso plurale, l’apparato di punizione un dispositivo per stare in guardia e salvare.

Este estudo objetivou identificar o nível de satisfação dos discentes de programas de mestrado e doutorado da área de negócios com as mudanças introduzidas pelas instituições de ensino superior para viabilizar a continuidade do curso frente ao contexto de pandemia provocada pela Covid-19. Para atender ao objetivo proposto, aplicou-se um questionário em 101 discentes matriculados em programas da área de negócios no primeiro semestre de 2020. Como principais resultados, foi possível constatar que os participantes do estudo mostraram, em média, um nível de satisfação moderado em relação às adaptações introduzidas pelas instituições de ensino no contexto da Covid-19. Além disso, foi possível identificar que características pessoais (gênero, estado civil, idade e número de filhos) e o contato prévio com cursos de longa duração em EAD foram estatisticamente significativos para explicar as diferenças nos níveis motivacionais apresentados. Foi evidenciado, ainda, que quanto mais satisfeito em relação às mudanças o estudante estava, maior era a sua propensão para indicar um curso stricto sensu 100% em EAD para um amigo. Entre os principais descontentamentos em relação às adaptações utilizadas pelas instituições, está a percepção de baixo desenvolvimento das habilidades necessárias para a atuação futura como docente, a percepção de baixa interação entre os discentes durante o ensino remoto emergencial e as dificuldades para aprofundar no conhecimento na modalidade EAD. Os resultados da pesquisa permitem refletir sobre os impactos da Covid-19 e a introdução da EAD na pós-graduação stricto sensu no Brasil.

Published: March 2024

Considerando a complexidade da mensuração das ações de Educação Corporativa e a crescente demanda de comprovação do retorno que treinamentos e outras soluções educacionais trazem para as organizações, o objetivo deste ensaio teórico é propor um modelo conceitual que analise como a Educação Corporativa pode ser avaliada por meio de melhorias nas rotinas organizacionais e de inovações de processos. O modelo proposto recomenda indicadores específicos para mensurar tais impactos, favorecendo o alinhamento da Educação Corporativa com a estratégia organizacional. O modelo conceitual possui oportunidades de aplicação prática em setores de Treinamento & Desenvolvimento, Universidades Corporativas e escolas de negócio.
