Published: March 2023

The purpose of this study was to develop and apply an elementary English instructional model based on CLIL(Content and Language Integrated Learning). It attempted to analyze students’ perceptions of CLIL-based elementary English classes. The research was carried out with two classes of fifth graders at an elementary school in Seoul.
The speech between the teacher and students was collected and transcribed. Also, a semi-structured student interview was conducted to probe the learners’ perceptions.
The result showed that the students had a high degree of satisfaction with the classes based on CLIL. According to the student responses, CLIL motivated them and increased their chances of using English. However, there were also drawbacks for participating in the CLIL classes. For example, some students needed more time or materials to comprehend the lessons. In addition, some pedagogical implications and suggestions for developing CLIL-based elementary English instructional model are included.

Published: March 2023

Objetivo: Avaliar, através da revisão de literatura, a etiologia que leva a pigmentação das restaurações de resina composta e mencionar alternativas clínicas para prevenir esse aspecto indesejado. Revisão Bibliográfica: A estética possui um papel fundamental na odontologia, sendo os materiais restauradores estéticos desenvolvidos para reproduzir as melhores características ópticas dos tecidos dentais. Sendo assim, mesmo que vitais, dentes escurecidos podem prejudicar muito a estética do sorriso. Portanto, é necessário que o profissional oriente seus pacientes sobre os agentes pigmentantes extrínsecos e sobre os mecanismos que interferem e intensificam um achamento dos materiais restauradores estéticos, visando a conservação da sua estabilidade e a longevidade da restauração. Por outro lado, as causas extrínsecas são relacionadas com a absorção de corantes resultantes de fontes exógenas provenientes de alimentos e de algumas bebidas. Considerações finais: As resinas compostas são os materiais mais utilizados em restaurações diretas e indiretas e, com base nos resultados deste estudo, pode-se concluir que a pigmentação resulta de fatores intrínsecos e extrínsecos. A conduta clínica tomada pelo cirurgião-dentista pode ajudar na prevenção ou redução desses manchamentos através de adequada técnica de confecção das restaurações.

Published: March 2023

Objectives:

The study aimed to comparatively evaluate the patients’ experiences with these treatments by analyzing the contents of the posts shared by the patients with clear aligner and fixed orthodontic treatment (FOT).

Material and Methods:

To reach the treatment methods, the hashtags “braces” for FOT and “aligner” for clear aligner treatment (CAT) were used in the Instagram search engine. To reach objective patient evaluations, clinicians’ posts, company posts, and influencers’ posts containing advertisements and collaborations were eliminated and direct patient posts were considered. Seventy-nine posts were included in the FOT group and 52 posts in the CAT group. The posts were evaluated comparatively in terms of the number of likes, followers of the profiles, comments and content, the gender of the patients, and the treatment stage.

Results:

According to the results of the analysis, although the number of followers, likes, comments, and positive and neutral comments were higher in favor of the aligner group between the FOT and CAT groups, the rate of likes/followers was found to be higher in favor of the fixed treatment group (P < 0.05).

Conclusion:

Considering the literature, although studies on CATs on social media are limited, this media is seen as an effective factor in the treatment decision-making process of patients. While the most negative comments of individuals in fixed treatment were psychological effects, the most criticized issue in CAT was treatment fees.
The First Walter Cobbett’s Competition: The Phantasies of William Hurlstone, Frank Bridge and Haydn Wood
Authors: Романычева А.Н.
Published: March 2023

Английская музыкальная культура первой половины XX века становится настоящим кладезем произведений, написанных в жанре камерно-инструментальной фантазии. В его традиции прослеживаются две линии: первая связана с романтической фантазией, написанной на одну или несколько тем (авторских или заимствованных), вторая — с совершенно уникальной в музыкальной истории инициативой английского бизнесмена Уолтера Коббетта, повлекшей за собой появление фантазий в  творчестве практически всех английских композиторов того времени. Учрежденный Коббеттом в 1905 году конкурс имел амбициозные планы: «закрыть брешь» в камерной музыке, образовавшуюся ввиду отсутствия, на его взгляд, альтернативы сонатной форме для написания крупного одночастного произведения. Прототипом для новой английской фантазии стала консортная фантазия эпохи Возрождения. В  статье рассматриваются сочинения победителей первого конкурса Уолтера Коббетта — Уильяма Хёрлстоуна, Фрэнка Бриджа и Гайдна Вуда.

English musical culture of the first half of the XX century becomes a real treasure trove of works written in the genre of chamber fantasy. In its tradition two lines can be traced: the first is connected with the romantic fantasy written on some theme or themes (original or borrowed), the second — with a unique in the history of music initiative of an English businessman Walter Cobbett, which entailed appearance of phantasies in the art of almost all English composers of that time. Founded by Cobbett in 1905, the competition had an ambitious plan to “fill the gap” in chamber music, which is, in his opinion, due to absence of an alternative to the sonata form in writing a major one-movement work. The prototype for the new English phantasy (old spelling) was the Renaissance consort fantasy. This article examines works of winners of Walter Cobbett's first competition — William Hurlstone, Frank Bridge, and Haydn Wood. Keywords: English chamber music, English consort phantasy, Walter Cobbett’s competition, William Hurlstone, Frank Bridge, Haydn Wood.

Published: March 2023

Solution self-assembly of amphiphilic block copolymers (BCs) is typically performed by solvent to water exchange. However, BC assemblies are often trapped in metastable states depending on the mixing conditions, such as the magni-tude and rate of water addition. BC self-assembly can be performed under near thermodynamic control by dialysis which accounts for a slow and gradual water addition. In this communication we report the use of a specifically de-signed dialysis cell to continuously monitor by dynamic light scattering and small-angle neutron scattering the mor-phological changes of PDMS-b-PEG BCs during THF to water exchange. The complete phase diagrams of near-equilibrium structures can then be established. Spherical micelles first form before evolving to rod-like micelles and vesicles, decreasing the total developed interfacial area of self-assembled structures in response to increasing interfacial energy as the water content increases. The dialysis kinetics can be tailored to the time scale of BC self-assembly by modifying the membrane pore size, which is of interest to study the interplay between thermodynamics and kinetics in self-assembly pathways.
Battery lifetime predictions: information leakage from unblinded training
Authors: Geslin Alexis , van Vlijmen Bruis , Cui Xiao , Bhargava Arjun , Asinger Patrick , Braatz Richard , Chueh William
Published: March 2023

Data-driven models are being developed to predict battery lifetime because of their ability to capture complex aging phenomena. In this perspective, we demonstrate that it is critical to consider the use cases when developing prediction models. Specifically, model features need to be classified to di↵erentiate whether or not they encode cycling conditions, which are sometimes used to artificially increase the diversity in battery lifetime. Many use cases require the prediction of cell- to-cell variability between identically cycled cells, such as production quality control. Developing models for such prediction tasks thus requires features that are blind to cycling conditions. Using the dataset published by Severson et al. in 2019 as an example, we show that features encoding cycling conditions boost model accuracy because they predict the protocol-to-protocol variability. However, models based on these features are less transferable when deployed on identically cycled cells. Our analysis underscores the concept of using the right features for the right prediction task. We encourage researchers to consider the usage scenarios they are developing models for, and whether or not to blind their model from information on cycling conditions in order to avoid information leakage. Equally important, benchmarking model performance should be carried out between models developed for the same use case.
Degradation of Perfluorooctanoic Acid (PFOA) on Aluminum Oxide Surfaces: New Mechanisms from Ab Initio Molecular Dynamics Simulations
Authors: Biswas Sohag , Wong Bryan
Published: March 2023

Perfluorooctanoic acid (PFOA) is a part of a large group of anthropogenic, persistent, and bio-accumulative contaminants known as per- and polyfluoroalkyl substances (PFAS) that can be harmful to human health. In this work, we present the first ab initio molecular dynamics (AIMD) study for systematically investigating a wide range of temperature-dependent degradation dynamics of PFOA on (100) and (110) surfaces of gamma-Al2O3. Our results show that PFOA degradation does not occur on the pristine (100) surface, even when carried out at high temperatures. However, introducing an oxygen vacancy on the (100) surface facilitates an ultra-fast (< 100 fs) defluorination of C-F bonds in PFOA. We also examined degradation dynamics on the (110) surface and found that PFOA interacts strongly with Al(III) centers on the surface of gamma-Al2O3, resulting in a stepwise breaking of C-F, C-C, and C-COO bonds. Most importantly, at the end of the degradation process, strong Al-F bonds are formed on the mineralized gamma-Al2O3 surface, which prevents further dissociation of fluorine into the surrounding environment. Taken together, our AIMD simulations provide critical reaction mechanisms at a quantum level of detail and highlight the importance of temperature effects, defects, and surface facets for PFOA degradation on reactive surfaces, which have not been systematically explored or analyzed.

Piezochromic materials with pressure-dependent photoluminescence-tuning properties are important in many fields, such as mechanical sensors, security papers, and storage devices. Covalent organic frameworks (COFs), as an emerging class of crystalline porous materials (CPMs), feature structural dynamics and tunable photophysical properties, which are suitable for designing piezochromic materials, but related research is scarce. Herein, we report two dynamic three-dimensional COFs based on aggregation-induced emission (AIE) or aggregation-caused quenching (ACQ) chromophores, termed JUC-635 and JUC-636, and for the first time, study their piezochromic behavior by diamond anvil cell technique. Due to the various luminescent groups, JUC-635 has completely different solvatochromism and molecular aggregation behavior in the solvents. More importantly, JUC-635 with AIE effect exhibited a maintained fluorescence with increasing pressure (~3 GPa), and a reversible sensitivity with high-contrast emission differences (Δλem = 187 nm) up to 12 GPa, which is superior to other CPMs reported so far. Therefore, this research will open a new gate for expanding the potential applications of COFs as exceptional piezochromic materials in pressure sensing, barcoding, and signal switching.

Degradation is a technical and market hurdle in the development of novel photovoltaics and other energy devices. Understanding and addressing degradation requires complex, time-consuming measurements on multiple samples. To address this challenge, we present \textit{DeepDeg}, a machine learning model that combines deep learning, explainable machine learning, and physical modeling to: 1) forecast hundreds of hours of degradation, and 2) explain degradation in novel photovoltaics. Using a large and diverse dataset of over 785 stability tests of organic solar cells, totaling 230,000 measurement hours, DeepDeg is able to accurately predict degradation dynamics and explain the physiochemical factors driving them using few initial hours of degradation. We use cross-validation and a held-out dataset of over 9,000 hours of degradation of PCE10:OIDTBR to evaluate our model. We demonstrate that by using DeepDeg, degradation characterization and screening can be accelerated by 5-20x.
RT-Tranformer: Retention Time Prediction for Metabolite Annotation to Assist in Metabolite Identification
Authors: xue jun , Wang Bingyi , li Weihua
Published: March 2023

Liquid chromatography retention times (RTs) prediction can assist in metabolite identification, which is a critical task and challenge in non-targeted metabolomics.However, different chromatographic methods (CM) may result in different RTs for the same metabolite. Current RT prediction methods lack sufficient scalability to transfer from one specific chromatographic method to another. Therefore, we present RT-Transformer, a novel deep neural network model coupled with graph attention network (GAT) and 1D-Transformer, which can predict RTs under any chromatographic methods. First, we obtain a pre-trained model by training RT-Transformer on the large small molecule retention time (SMRT) dataset containing 80038 molecules, and then project the resulting model onto different chromatographic methods based on transfer learning. When tested on the METLIN dataset, as other authors did, the average absolute error reached 27.30 after removing samples with retention times fewer than five minutes. Still, it reached 33.41 when no samples were removed. The pre-trained　RT-Transformer was further transferred to 5 datasets corresponding to different chromatographic conditions and fine-tuned. According to the experimental results, RT-Transformer achieves competitive performance compared to state-of-the-art methods.In addition, RT-Transformer was applied to 41 external molecular RT datasets. Extensive evaluations indicate that RT-Transformer has excellent scalability in predicting RTs for liquid chromatography and improves the accuracy of metabolite identification.
Is there any correlation between impedance shapes and electrocatalytic activity?
Authors: Huang Jun
Published: March 2023

Though electrochemical impedance spectroscopy (EIS) has been widely used in mechanistic investigations of electrocatalytic reactions, the correlation between the shape of an EIS diagram and electrocatalytic activity is largely unclear; the rich complexity of electrocatalytic reactions casts an air of pessimism over the existence and stability of such a correlation. Understanding the correlation can help select reaction mechanisms and electrical circuit models in data analysis, use EIS shape as a descriptor of electrocatalytic activity, and detect side reactions. Herein, the problem is tackled by a systematic mathematical analysis of firstly single-adsorbate reactions and then more complicated reactions. A complete regime diagram of all possible EIS shapes of single-adsorbate reactions is provided, navigating the analysis in the multi-dimensional parametric space. For single-adsorbate reactions involving two steps with identical transfer coefficients of 0.5 in the absence of lateral adsorbate interactions, several rigorous corollaries are derived. Most of them fail miserably when different transfer coefficients and lateral interactions are considered. Nevertheless, several trends in EIS shapes are robust against complexities of reaction mechanisms and variations in reaction parameters, which also receive experimental evidence collected from the literature.
A Förster Resonance Energy Transfer Assay for Investigating the Reactivity of Thioesters
Authors: Gless Bengt , Schmied Sabrina , Olsen Christian Adam
Published: March 2023

The sulfur–carbonyl bond in a thioester is an “energy-rich” functionality but is hydrolytically stable, while susceptible to attack by thiolate and amine nucleophiles, enabling thioester chemistry to take place in aqueous medium. In this work, we developed a fluorogenic assay format for the direct and continuous investigation of the rate of reaction between thioesters and nucleophiles under various conditions. We designed three different substrates, mimicking the chemical environment in acyl-CoA, S-acylcysteine, and an activated thioester commonly used in chemical protein synthesis by native chemical ligation. The data resulting from monitoring of the reaction of these substrates with a series of nucleophiles at varying pH values generally recapitulated previously reported reactivity of thioesters. We investigated key aspects of native chemical ligation reaction conditions. Our data revealed a profound effect of the tris-(2-carboxyethyl)phosphine (TCEP) commonly used in systems where thiol–thioester exchange occurs, including a potentially harmful hydrolysis side reaction. These data provide insight for potential optimization of native chemical ligation chemistry.
“A Mass Exodus in Rebellion” – The Migrant Caravans: A View from the Eyes of Honduran Journalist Inmer Gerardo Chévez
Authors: Alvarez Velasco Soledad , De Genova Nicholas
Published: March 2023

This article analyzes the migrant caravans as a strategy of resistance to the war against migrants in transit to the United States, exacerbated during the pandemic. This is the edited transcript of an interview conducted with Honduran journalist Inmer Gerardo Chevez, correspondent of Radio Progreso. Having travelled the Central American and Mexican routes accompanying on foot the transit of thousands of migrants since 2018, Chevez is a notable eyewitness and expert in situ of the Caravans. The interview confirms that the caravan has become one of the premier forms in which Latin American migrants, including agricultural workers, struggle and their spatial dispute with the heterogeneous border control regime of the Americas are materialized. The text also reflects on the role that photography and critical journalism can play in the face of the contemporary anti-migrant policy turn. We conclude with an interpretation of the effects that the militarized violence against Latin American migrants in transit to the United States is having across the region.

The concept of sanctuary cities has been in consistent development since 1971. There are conceptual differences between the contexts of sanctuary cities located in North America and those located in the European Union. The services and benefits offered to foreign immigrants in the city of São Paulo, in North America and in the European Union were identified through documentary analysis; allocated between three perspectives, namely, social, political and legal; and classified under eight criteria of analysis. Thus, the objective of this research was to analyze whether the services and benefits offered in the city of São Paulo to foreign immigrants configure São Paulo as a sanctuary city. The results indicate that the city of São Paulo offers 11% more benefits than sanctuary cities in the European Union and 14% more benefits than sanctuary cities in North America from a political perspective. However, the city of São Paulo offers 15% fewer benefits than sanctuary cities in the European Union and 31% fewer benefits than sanctuary cities in North America from a legal perspective. Finally, an analysis of the social perspective shows a balance in the benefits offered in the three locations. This work contributes to forming a clearer managerial view of the public governance and public policies present in the city of São Paulo and paves the way for the development of future studies on the subject in the social context found within this municipality.

Introduction: This study aimed to determine the lowest possible atmospheric pressure in the 111−152 kPa (1.1−1.5 atmospheres absolute [atm abs]) range that would require the patients to equalise their ears, allowing an effective sham for a 203 kPa (2.0 atm abs) hyperbaric exposure. Methods: We performed a randomised controlled study on 60 volunteers divided into 3 groups (compression to 111, 132 and 152 kPa (1.1, 1.3, 1.5 atm abs) to determine the minimum pressure to obtain blinding. Secondly, we applied additional blinding strategies (faster compression with ventilation during the fictitious compression time, heating at compression, cooling at decompression) on 25 new volunteers in order to enhance blinding. Results: The number of participants who did not believe they had been compressed to 203 kPa was significantly higher in the 111 kPa compressed arm than in the other two arms (11/18 vs 5/19 and 4/18 respectively; P = 0.049 and P = 0.041, Fisher’s exact test). There was no difference between compressions to 132 and 152 kPa. By applying additional blinding strategies, the number of participants who believed they had been compressed to 203 kPa increased to 86.5 %. Conclusions: A compression to 132 kPa, (1.3 atm abs, 3 metres of seawater equivalent) combined with the additional blinding strategies of forced ventilation, enclosure heating and compression in five minutes, simulates a therapeutic compression table and can be used as a hyperbaric placebo.

Authors: DOĞAN Saime
Published: March 2023

At the macro level, the indicator of a high-quality economy is a high-quality production system. Meanwhile, a qualified production system can be achieved through qualified technological knowledge and applications that emerge as a result of Research and Development (R&D) activities. In today's technological world, R&D expenditures, which are widely used in the assessment of R&D, are now essential for the continuity and competitiveness of business enterprises. A production system based on R&D not only increases productivity and quality but also provides significant advantages in terms of cost. The purpose of this study is to investigate the effects of R&D expenditures on the sales and profitability of business enterprises. In line with this purpose, the relationship between R&D expenditures, sales and profitability of 20 manufacturing companies that are included in the BIST-100 index is investigated using the annual data for the period 2009-2021. In this analysis, the static panel data analysis with fixed effects proposed by Hansen (1999) is used. In conclusion, it is determined that investments made in the field of R&D two periods ago led to a regime shift in sales and profitability. Moreover, it is concluded that R&D investments should be kept at a certain level in order to increase sales and profitability.

Image transformation is important to obtain and find certain information about an image that was not previously known, such as pixels, geometry, size, and color. Following this, this research aims to analyze image transformation in producing better values using threshold and segmentation methods. The segmentation process is carried out based on two color models, namely hue saturation value (HSV) and red green blue (RGB). The image data used in this study was the x-ray image of the lungs from www.fk.unair.ac.id. which is processed using the Matlab 2021a application to help the analysis process.  on the results of the image segmentation analysis carried out in this case, the greater the HSV and RGB threshold values used in the image data, the better and clearer the segmentation of the detected image results. In other words, the size of the thresholding value generated greatly affects the quality, brightness, size, and color of the resulting image. The best lung X-ray image segmentation results were obtained when using the threshold values HSV = 0.9 and RGB = 9.

Abstract

Social media is a platform that allows users to express themselves freely including spreading hate speech content. The government has issued the regulation in the UU ITE to handle and prevent hate speech on social media. The research was also conducted using the Bi-LSTM to classify the text into hate speech or not. Another research was purposed to detect hate speech and its categories using Bi-GRU. However, the performance of the model Bi-GRU is still lower than Bi-LSTM with an accuracy of 86.44% and 96.44%. Therefore, this study aims to build a model that can detect hate speech and its categories. The research offers Bi-LSTM as a classification model and IndoBERT as a tokenization model. The dataset used is a public dataset containing 13 thousand tweets. As a result, the best model obtained is using 20 epochs, 192 batch sizes, 1 layer Bi-LSTM with 40 nodes, and applying class weighing in the optimization process. The pre-train model from IndoBERT that is used to support the performance of the model in classifying is "indobenchmark/indobert-large-p2". The performance given by the purposed model is very good with an average accuracy, precision, and recall of 97.66%, 96.50%, and 85.25%.

Os Espaços Não Formais (ENFs) têm revelado grandes contribuições para a ampliação da cultura científica, a partir de aulas motivadoras e que geram ganho cognitivo nos alunos. Abordar o potencial contribuidor dos ENFs desde a formação inicial dos professores contribuirá com a possibilidade do maior uso desses espaços em seu planejamento. Nesse contexto, o trabalho teve por objetivo discutir o potencial contribuidor dos ENFs da Amazônia na Formação de Professores em Boa Vista - RR, na perspectiva de uma desmistificação quanto ao uso desses espaços no planejamento docente. O presente trabalho contempla uma abordagem qualitativa, de objetivo exploratório e descritivo, realizado com 10 acadêmicos das licenciaturas em Química e Ciências Biológicas da Universidade Estadual de Roraima (UERR), a partir de um curso de capacitação para os professores em formação, sobre a temática “Os Espaços Não Formais de Boa Vista/RR e seu potencial contribuidor para o Ensino de Ciências”. Verificou-se que a discussão sobre o tema aumentou o número de ENFs conhecidos pelos acadêmicos, assim como ampliou os olhares dos futuros professores quanto ao uso desses espaços em sua prática pedagógica. Pode-se concluir ainda que apesar de a maioria dos acadêmicos reconhecerem algumas contribuições do uso dos ENFs para o processo de ensino e aprendizagem, ainda há a importância da reflexão sobre a necessidade de romper com as desmistificações na formação de professores que tendem a utilizar meios defasados e que pouco contribuem para a Educação em Ciências.
A pseudoqualidade da gestão integrada da escola (GIDE) na SEMED/Manaus
Authors: De Lima Pereira Luciana , Suely Baçal de Oliveira Selma
Published: March 2023

Este artigo faz um convite à leitura da tese denominada Escola não é empresa: a pseudoqualidade da GIDE nas escolas de Manaus, que foi premiada, na área da Educação, pela Pró-Reitoria de Pesquisa e Pós-Graduação da Universidade Federal do Amazonas (Propesp/UFAM), no ano de 2021. Problematiza a enunciada qualidade educacional propagada pela GIDE na Semed/Manaus no período de 2014 a 2018, sob a consultoria da Empresa Instituto Áquila. Fundamenta-se em autores clássicos e contemporâneos tanto da tradição marxista quanto empresarial. A pesquisa baseia-se em análise documental, de contratos estabelecidos entre a Semed/Manaus e a Empresa Instituto Áquila, além de questionários e entrevistas semiestruturadas. Conclui que, por meio da GIDE com seus elementos rígidos de monitoramento do trabalho escolar, a Rede Municipal de Ensino colabora para o preparo da barata mão de obra, “certificada” e facilmente substituível do Polo Industrial de Manaus. Deste modo, a tese ora apresentada contribui para o enfrentamento dos inúmeros desafios amazônicos, uma vez que aborda uma temática de inegável relevância que necessita ser integrada a estudos similares tanto no âmbito local quanto em outros países da América Latina que convivem com processos similares de privatização da gestão e pedagógicos. Destaca que a prática empresarial levada a efeito por meio da GIDE replicada nas escolas de Manaus produz uma pseudoqualidade do ensino e resultará na desqualificação do trabalho peculiar da própria escola.

Published: March 2023

O presente trabalho analisa o processo do ensino-aprendizagem dos conteúdos de orientação cartográfica da 7ª classe na disciplina de geografia. Para o estudo, foram seleccionadas (3) três escolas no município de Porto Amboim as quais tiveram a denominação de A, B e C. Para avaliação da situação em estudo foram aplicados questionários/inquéritos aos professores e alunos e, ao corpo directivo foi efectuada uma entrevista. Em cada escola foram seleccionados (60) sessenta alunos Tomou-se como base para a escolha destes os números primos e ímpares. Quanto aos professores foram seleccionados 14 distribuídos do seguinte modo; 6 da escola A, 6 da escola B e 2 da escola C, dos quais (3) três são coordenadores da disciplina de geografia. O corpo directivo integrou os directores gerais e subdirectores pedagógicos de cada escola. Os resultados dos inquéritos/questionários e entrevistas foram processados e apresentados em gráficos. Das análises feitas verifica-se que as aulas teóricas nos conteúdos de orientação cartográfica não têm sido acompanhadas com as aulas práticas por um lado e, Por outro lado, da leitura feita ao programa da disciplina de geografia da 7ª classe constatou-se que a distribuição dos tempos lectivos varia em função do trimestre e que existem (3) três horas de reservas, as quais se sugere a sua utilização nas aulas práticas. Neste trabalho propõe-se um sistema de acções didácticos-práticas que poderia ser um instrumento para o desenvolvimento de habilidades cartográficas nos alunos, no processo de ensino-aprendizagem da disciplina de geografia na 7ª classe.
O que pode a medida socioeducativa de internação?
Authors: Miranda Gabriel , Lemos de Paiva Ilana
Published: March 2023

O presente artigo, de caráter teórico e exploratório, pretende, em primeiro lugar, demonstrar como, por uma característica intrínseca às sanções privativas de liberdade, a medida socioeducativa de internação fracassa na realização de seu objetivo declarado de promover uma ruptura com a trajetória infracional. Em seguida, diante do reconhecimento dessa limitação, são desenvolvidos dois pressupostos teórico-metodológicos com vistas a promover a ideia de que a execução da medida socioeducativa pode superar perspectivas autoritárias e assistencialistas, caracterizando-se como uma prática marcada pelo desenvolvimento de processos de autonomia, autorresponsabilização e expansão das possibilidades do adolescente ver, estar e se relacionar com o mundo.

Amazônia brasileira: educação e contexto
Authors: Conceição de Vasconcelos Tapajós Sousa Eli , Alencar Colares Anselmo
Published: March 2023

O texto proposto tem por objetivo apresentar um panorama da região amazônica e suas várias realidades, o contexto socioeconômico e educacional e como isso reflete no desenvolvimento da região, bem como debates acerca das políticas da Educação na e da Amazônia, a organização dos processos educativos e seus desafios. Destacam-se aspectos históricos sobre o surgimento das instituições escolares em Santarém/PA, um dos municípios que compõem a Amazônia brasileira e como esse fato influenciou no contexto histórico e no desenvolvimento da região. Tem o materialismo histórico-dialético como método de interpretação da realidade, visto que aponta caminhos para a compreensão dos fatos que ocorrem na prática social. Conclui-se que o progresso social só acontecerá, de fato, quando os interesses do capital, que dominam as políticas existentes na região, estiverem voltados para atender as populações que habitam e dependem dele para a sua sobrevivência.
