Differential Regulation of Prelimbic and Thalamic Transmission to the Basolateral Amygdala by Acetylcholine Receptors
Authors: Tryon Sarah C. , Bratsch-Prince Joshua X. , Warren James W. , Jones Grace C. , McDonald Alexander J. , Mott David D.
Published: December 2022

The amygdalar anterior basolateral nucleus (BLa) plays a vital role in emotional behaviors. This region receives dense cholinergic projections from basal forebrain which are critical in regulating neuronal activity in BLa. Cholinergic signaling in BLa has also been shown to modulate afferent glutamatergic inputs to this region. However, these studies, which have used cholinergic agonists or prolonged optogenetic stimulation of cholinergic fibers, may not reflect the effect of physiological acetylcholine release in the BLa. To better understand these effects of acetylcholine, we have used electrophysiology and optogenetics in male and female mouse brain slices to examine cholinergic regulation of afferent BLa input from cortex and midline thalamic nuclei. Phasic ACh release evoked by single pulse stimulation of cholinergic terminals had a biphasic effect on transmission at cortical input, producing rapid nicotinic receptor-mediated facilitation followed by slower mAChR-mediated depression. In contrast, at this same input, sustained ACh elevation through application of the cholinesterase inhibitor physostigmine suppressed glutamatergic transmission through mAChRs only. This suppression was not observed at midline thalamic nuclei inputs to BLa. In agreement with this pathway specificity, the mAChR agonist, muscarine more potently suppressed transmission at inputs from prelimbic cortex than thalamus. Muscarinic inhibition at prelimbic cortex input required presynaptic M4 mAChRs, while at thalamic input it depended on M3 mAChR-mediated stimulation of retrograde endocannabinoid signaling. Muscarinic inhibition at both pathways was frequency-dependent, allowing only high-frequency activity to pass. These findings demonstrate complex cholinergic regulation of afferent input to BLa that is pathway-specific and frequency-dependent.

SIGNIFICANCE STATEMENTCholinergic modulation of the basolateral amygdala regulates formation of emotional memories, but the underlying mechanisms are not well understood. Here, we show, using mouse brain slices, that ACh differentially regulates afferent transmission to the BLa from cortex and midline thalamic nuclei. Fast, phasic ACh release from a single optical stimulation biphasically regulates glutamatergic transmission at cortical inputs through nicotinic and muscarinic receptors, suggesting that cholinergic neuromodulation can serve precise, computational roles in the BLa. In contrast, sustained ACh elevation regulates cortical input through muscarinic receptors only. This muscarinic regulation is pathway-specific with cortical input inhibited more strongly than midline thalamic nuclei input. Specific targeting of these cholinergic receptors may thus provide a therapeutic strategy to bias amygdalar processing and regulate emotional memory.

Coastal seas and estuaries are among the most productive ecosystems on Earth and have long attracted human activity. Yet, urbanization pressures are intense and are compounded by accelerating climate stresses. Urban seas are now hotspots of stress in the Anthropocene ocean. The Salish Sea stands out as one of a few highly functioning urban seas in the world, boasting ecological riches and thriving coastal communities and industries, including tourism. For over 10,000 years the region has supported Indigenous peoples; now it is home to a growing population of almost nine million people, concentrated in and near the major cities of Seattle, Washington, and Vancouver, British Columbia. Increasing urbanization combined with intensifying climate stress is degrading the Salish Sea and acutely affecting communities already experiencing marginalization. Current environmental impacts include acidifying waters, hypoxia, and intense heat waves, all of which have had measurable impacts within the ecosystem. A recent synthesis of this system identified key domains for solutions, which we generalize here for invoking positive change in global urban seas: 1) innovation in data collection, curation, and integration using a systems approach in science and management; 2) sharing place-based knowledge to sustain community-based action; and 3) aligning science and policy with ecosystem boundaries. The differing governance and socio-political settings across two countries and numerous Indigenous nations creates a complex challenge in ecosystem management. Developing actionable solutions for people and the biota of the Salish Sea can create a global example of a sustainably managed urban sea with transferable insights to other urban seas in need of revitalization around the world.

Published: December 2022

One of the local honey of South Sulawesi is Trigona honey which comes from Trigona spp. There are three types of trigona bees in South Sulawesi with each colony consisting of 300-80,000 individuals. Trigona bees are found nesting in hollow places such as logs, tree holes, and cracks in the walls of houses. The nest entrance is made of plant resin mixed with soil and mud, with different shapes and colors depending on the species. This type of bee produces a lot of propolis compared to honey and the price of honey produced is much higher because it has a chemical content (health benefits) that is much better than ordinary honey from the Apis mellifera group. This study was designed by extracting in ethanolic process at a concentration of 70%. The choice of concentration was based on previous research with an extraction temperature of 60 °C. The treatment of this research is to vary the time, namely 10 minutes, 20 minutes, and 30 minutes as a setting for the extraction time. Each treatment will be carried out in duplicate. This shows that in the honeycomb waste Trigona spp. contains terpenoids which are classified as antioxidants. Therefore, beehive waste Trigona spp. potential to be used as a source of antioxidants. In addition, several compounds are also relatively large antibacterial and anti-microbial compounds contained in the waste of Trigona spp beehives. The optimum solvent used by comparing the percentage of abundance (abundance/relative) through the percentage of the area and molecular stability after fragmentation is through the ethanolic process using ethanol solvent with percent abundance at 218 m/z and 189 m/z with the largest compound contained is Methyl Commate A and Alpha-Amyrin

Solid waste management on Nusa Penida Island is one of the problems in tourism in Bali Province. To deal with this issue, the government has implemented various policies, where the policy that becomes an essential issue is the processing of energy waste. To support this, it is necessary to study the potential of waste characteristics on the island of Nusa Penida. This study aims to analyse the characteristics of waste on the island of Nusa Penida as an energy source based on the generation and composition of waste. Solid waste generation and composition were measured based on land and marine debris data. The total waste generation on land and marine debris can reach 6364.4 kg/day and 762.8 kg/day, respectively. The waste composition materials consist of masks, plastics, metals, and biodegradable organics with a value of 4.12%, 32.77%, 19.54%, and 43.57%, respectively. Therefore, the potential use of organic biodegradable as solid fuel can reach 51,933.8 MJ/day or 14,426 kWh/day. However, in the thermogravimetric analysis (TGA) test, the residue was 18.6%.
The Effect of Solvent Ratio and Extraction Time on Antioxidant Activity and Flavonoid Concentration of Kedawung Leaf (Parkia Biglobosa) Through Microwave-Assisted Extraction
Authors: Indrasari Ferika , Buanasari Buanasari
Published: December 2022

Kedawung (Parkia biglobosa) contains various ingredients such as alkaloids, saponins, tannins, flavonoids, and terpenoids. The flavonoid content in Kedawung is thought to have an antioxidant effect. Antioxidants are able to counteract free radicals that enter the body by donating electrons and binding them. Currently, the microwave-assisted extraction (MAE) method is widely used because the solute mass transfer from the sample matrix into the solvent is higher than the Soxhlet method. The following study aimed to know the effect of solvent ratio and extraction time on the extraction yield, flavonoid concentration, and antioxidant activity of kedawung leaf through microwave-assisted extraction. In this method, we used 40% ethanol to make the varied solute: solvent ratio such as 1:20, 1:30, 1:40, and 1:50. The extraction time used in this method was 4-7 minutes respectively. Microwave-assisted extraction has good performance to extract the active substance in Kedawung leaves. The highest yield 16.36%, total flavonoid content (57.32±2,2 mg QE/g extract), and DPPH scavenging activity (88.87±1.062%) was obtained in the extraction with a solids-solvent ratio of 1:40 g/mL, at an extraction time of 6 minutes. This method promises to take the active substance in a short time.

Published: December 2022

The eco-friendly brake composite has been still an interesting issue in the development of brake friction materials. Wastes of S. Macrophylla (mahogany) fruit skin and coal fly ash are available as organic ingredients of bio-composite brakes. In this research, we investigated the effects of both ingredients on the brake composite properties which were fabricated using hot isostatic pressing at temperature 200 °C and pressure 5 kN for 3 h. The specimens were prepared in some volume fractions of carbon (2 vol% - 12 vol%). As a result, several tested specimens containing mahogany fruit skin carbon revealed maximum Rockwell hardness 69 HRB, wear 2.49x10-4mm2/kg, and water absorption 2.72 %, while specimens containing coal fly ash showed 78 HRB, 1.1x10-3mm2/kg, and 3.5 %, respectively. The brake composites containing coal fly ash performed better than ones containing mahogany fruit skin carbon. The hardness and wear of these two types of brake composite friction materials meet the minimum criteria required by SAE, JA661, and are close to the quality of the brake pads of two commercial brake composite materials. Water absorption in the brake lining specimens with mahogany leather carbon showed that the addition of the volume fraction caused an increase in water absorption, while the specimen containing coal fly ash showed that the increase in the carbon volume fraction caused a decrease in water absorption.

En Andalucía se realizan diversas actuaciones para la catalogación y conservación de la biodiversidad por parte del gobierno autonómico. Con respecto a las plantas, es notable la creación de una red de Jardines Botánicos asociados a espacios naturales protegidos. Estos jardines y áreas protegidas contienen una buena representación de la flora y de las especies amenazadas andaluzas, lo que supone un gran potencial para la investigación en biodiversidad. En este artículo se exploran posibilidades que ofrecen estos jardines, dirigidas hacia la investigación y se muestran algunos resultados obtenidos. Estas investigaciones se dirigen por un lado hacia el pasado histórico que ha generado la actual diversidad evolutiva (filogenética) de la flora leñosa usando marcadores genéticos y genómicos. Por otro lado, la representación de flora amenazada en los jardines ha permitido conocer también su nivel de singularidad filogenética y compararla con su rareza basada en aspectos biogeográficos y ecológicos. Los Jardines Botánicos han proporcionado gran parte de las muestras de tejido vegetal para la extracción de ADN necesario para resolver las filogenias. Finalmente, se exponen posibilidades futuras de investigación para prevenir los efectos del cambio climático en los sistemas naturales de Andalucía, usando los jardines como estaciones de observación fenológica. La información sobre el pasado evolutivo es muy relevante para determinar su influencia en la respuesta de las plantas a los cambios que ya están aconteciendo

Published: December 2022

El exceso de herbivoría causa graves problemas de erosión, desertificación y pérdida de biodiversidad. Los vallados han sido ampliamente utilizados para controlar este problema, aunque se ha comprobado que estos vallados tienen a medio plazo tanto efectos positivos, como efectos negativos e indeseados. Sin embargo, no existen trabajos que evalúen su eficacia a medio-largo plazo. En este trabajo hemos seleccionado 6 especies de flora amenazada (localizadas en las Sierras de Cazorla, Segura y las Villas y Sierra de Mágina) que presentan poblaciones valladas y sin vallar. En estas poblaciones se tomaron en campo datos de las especies amenazadas y de distintos parámetros del hábitat. De esta forma se comprobó que los vallados disminuían en general la presencia y actividad de ungulados, pero en algunas ocasiones los individuos de las poblaciones valladas producían un menor número de flores y frutos. Las zonas valladas experimentaron un aumento significativo en la cobertura, aumentando la competencia interespecífica para las especies amenazadas. No hubo cambios drásti- cos en el suelo, aunque sí un incremento en algunos parámetros indicadores de exceso de herbivoría en algunas poblaciones no valladas. La conclusión más clara de este trabajo es que el efecto de los vallados, positivo o negativo, no es uniforme, sino que varía entre especies y entre poblaciones de la misma especie. Narcissus, Atropa y Glandora se vieron beneficiadas, mientras que Aquilegia, Euonymus y Gera- nium no recibieron un beneficio claro. Se pone de manifiesto la necesidad de evaluar periódicamente la eficacia de los vallados, así como la necesidad de ensayar y evaluar métodos alternativos (vallados individuales, temporales,etc.).

Published: December 2022

In order to investigate the relationship between production parameters and evaluation indexes for wood fiber production, a bi-directional prediction model was established to predict the fiber quality, energy consumption, and production parameters based on the improved particle swarm optimization and support vector machine (IPSO-SVM). SVM was applied to build the bi-directional prediction model, and IPSO was used to optimize the SVM parameters that affect the performance of prediction greatly. In the case of the forward prediction, the model can predict the fiber quality and energy consumption using the production parameters as input information; in the case of the backward prediction, the model can estimate production parameters using the fiber quality and energy consumption as evaluation indexes for input information. The results showed that the IPSO-SVM model had high accuracy and good generalization ability in the prediction for the wood fiber production. Additionally, based on the effectiveness of the proposed model and preset evaluation indexes, the corresponding production parameters were determined, which was able to save the wooden resources as well as reduce energy consumption in the fiberboard production.
Fully Continuous Leakage-Resilient Certificate-Based Signcryption Scheme for Mobile Communications
Authors: Tseng Yuh-Min , Tsai Tung-Tso , Huang Sen-Shan
Published: December 2022

Due to the popularity of mobile communication, many computing devices are exposed to remote environments without physical protection so that these devices easily suffer from leakage attacks (e.g., side-channel attacks). Under such leakage attacks, when a computing device performs some cryptographic algorithm, an adversary may acquire partial bits of secret keys participated in this cryptographic algorithm. To resist leakage attacks, researchers offer leakage-resilient cryptography as a solution. A signcryption scheme combines signing and encrypting processes to simultaneously provide both authentication and confidentiality, which is an important cryptographic primitive. Indeed, many leakage-resilient signcryption schemes under various public key system (PKS) settings were proposed. Unfortunately, these schemes still have two shortcomings, namely, bounded leakage resilience and conditionally continuous leakage resilience. In this paper, a “fully” continuous leakage-resilient certificate-based signcryption (FCLR-CBSC) scheme is proposed. Security analysis is formally proved to show that our scheme possesses both authentication and confidentiality against two types of adversaries in the certificate-based PKS setting. Performance analysis and simulation experience show that our scheme is suited to run on both a PC and a mobile device.

Published: December 2022

The aim of this study is to identify the psychosocial factors which are related with affiliate stigma in parents of children with ADHD through a systematic literature review. This review includes English publications from 2008 to 2022, which present the results of quantitative studies on the relationship between psychosocial factors and affiliate stigma in parents of children with ADHD. According to eligibility criteria, 7 articles were included in the review. The results showed that higher parental affiliate stigma is associated with lower parents’ psychosocial functioning (higher expressed depression, anxiety, lower self-esteem). It was also found that higher parental affiliate stigma is related to unfavorable behavior towards a child (higher expressed negativity/ less constructive parenting). The results also showed that higher parental affiliate stigma is associated with more expressed child's difficulties (ADHD symptoms/ internalizing and externalizing difficulties).

Puer renidens (Mart. Cap. 2.144). Revisited Topos of ‘Two Loves’ and intertextuality
Authors: Petrovićová Katarina
Published: December 2022

Love is one of the most frequent literary motifs, often differentiated in various forms. A plurality of words for love in ancient Greek corresponds to a plurality of their divine representations in particular works, and more generally in Ancient religious and philosophical images. The most famous concept is that of the two Loves which is represented in Plato's dialogue Symposium. In the paper, the author revises the standard interpretation of the ‘Two Loves Topos’, considered in Mart. 2. 144–148, literalized as the presence of Amor and absence of Cupid in Philology's suite during her journey to heaven, in terms of literary intertextuality. After a brief outline of the literary evidence of the ‘Two Loves Topos’, Martianus Capella's comprehensive picture is analysed, connecting the archaic opposition between Amor and Cupid and the Platonic division to support his compositional intention to create a ‘new’ comprehensive Love god person, who is in accordance with the unified and harmonious world of mythological, cosmological, and philosophical scholarship.

Authors: Bodyanskiy Ye. V. , Pliss I. P. , Shafronenko A. Yu.
Published: December 2022

Context. The task of clustering arrays of observations of an arbitrary nature is an integral part of Data Mining, and in the more general case of Data Science, a huge number of approaches have been proposed for its solution, which differ from each other both in a priori assumptions regarding the physical nature of the data and the problem, and in the mathematical apparatus. From a computational point of view, the clustering problem turns into a problem of finding local extrema of a multiextremal function of the vector density argument using gradient procedures that are repeatedly launched from different points of the initial data array. It is possible to speed up the process of searching for these extremes by using the ideas of evolutionary optimization, which includes algorithms inspired by nature, swarm algorithms, population algorithms, etc.

Objective. The purpose of the work is to introduce a data clustering procedure based on the peaks of the data distribution density and the evolutionary method of cat swarms, that combines the main advantages of methods for working with data in conditions of overlapping classes, is characterized by high-quality clustering, high speed and accuracy of the obtained results.

Method. The method for clustering data arrays based on the combined optimization of distribution density functions and the evolutionary method of cat swarms was proposed. The advantage of the proposed approach is to reduce the time for solving optimization problems in conditions where clusters are overlap.

Results. The results of the experiments confirm the effectiveness of the proposed approach in clustering problems under the condition of classes that overlap and allow us to recommend the proposed method for use in practice to solve problems of automatic clustering big data.

Conclusions. The method for clustering data arrays based on the combined optimization of distribution density functions and the evolutionary method of cat swarm was proposed. The advantage of the proposed approach is to reduce the time for solving optimization problems in conditions where clusters are overlap. The method is quite simple from the numerical implementation and is not critical for choosing an optimization procedure. The experimental results confirm the effectiveness of the proposed approach in clustering problems under conditions of overlapping clusters.
DATA CLUSTERING BASED ON INDUCTIVE LEARNING OF NEURO-FUZZY NETWORK WITH DISTANCE HASHING
Authors: Subbotin S. A.
Published: December 2022

Context. Cluster analysis is widely used to analyze data of various nature and dimensions. However, the known methods of cluster analysis are characterized by low speed and are demanding on computer memory resources due to the need to calculate pairwise distances between instances in a multidimensional feature space. In addition, the results of known methods of cluster analysis are difficult for human perception and analysis with a large number of features.

Objective. The purpose of the work is to increase the speed of cluster analysis, the interpretability of the resulting partition into clusters, as well as to reduce the requirements of cluster analysis to computer memory.

Method. A method for cluster analysis of multidimensional data is proposed, which for each instance calculates its hash based on the distance to the conditional center of coordinates, uses a one-dimensional coordinate along the hash axis to determine the distances between instances, considers the resulting hash as a pseudo-output feature, breaking it into intervals, which matches the labels pseudo-classes – clusters, having received a rough crisp partition of the feature space and sample instances, automatically generates a partition of input features into fuzzy terms, determines the rules for referring instances to clusters and, as a result, forms a fuzzy inference system of the Mamdani-Zadeh classifier type, which is further trained in the form of a neuro-fuzzy network to ensure acceptable values of the clustering quality functional. This makes it possible to reduce the number of terms and features used, to evaluate their contribution to making decisions about assigning instances to clusters, to increase the speed of data cluster analysis, and to increase the interpretability of the resulting data splitting into clusters.

Results. The mathematical support for solving the problem of cluster data analysis in conditions of large data dimensions has been developed. The experiments confirmed the operability of the developed mathematical support have been carried out.

Conclusions. . The developed method and its software implementation can be recommended for use in practice in the problems of analyzing data of various nature and dimensions.
Does the efficiency of public investment in human capital affect the country’s economic development?
Authors: Kozuń-Cieślak Grażyna
Published: December 2022

Modern theories of economic growth emphasize the meaning of the investment in human capital as the most profitable. Although the positive relationship between public investment in human capital and the country’s economic development is commonly accepted, the answer to the question of whether the efficiency of this investment is crucial for welfare, is no longer so obvious. The aim of this study is to recognize the relationship between the technical efficiency of public spending on human capital and the economic development in the sample of 28 EU states. For this purpose DEA method was applied to evaluate the efficiency of public expenditure on healthcare and education in order to build human capital. Then, DEA scores were correlated with countries’ economic development indicators expressed by GDP per capita. The study proves that the commonly accepted dependency between the potential of human capital and countries’ welfare is not reflected in the correlation between countries’ GDP per capita and the DEA efficiency of public investment in human capital

Language and identity in the East Frisian-American (postvernacular) heritage community
Authors: Rocker Maike
Published: December 2022

This article reports initial results from an online survey in the East Frisian heritage community in the United States, inquiring about remaining cultural and linguistic practices. Answers from 31 participants indicate a generally positive attitude towards the Low German heritage language, despite low self-reported productive and receptive proficiency. Community members show awareness of the ongoing and inevitable language shift to English but feel unable to stop the trend. This also manifests in terms of identity construction: while autochthonous minority language communities have been shown to employ emblematic language use as a postvernacular identity marker, East Frisian heritage in the U.S. is constructed mostly around church affiliation, food and tea traditions, shared values, and being “German.” Thus, this study opens the door for additional (comparative) studies on the development of postvernacular communities and the (diminished) role of language use in these groups.
Newspaper advertisements as an indicator of verticalization
Authors: Litty Samantha M.
Published: December 2022

Comparing advertisements published in both the English and German versions of the Eureka Post, a newspaper from Eureka, South Dakota, this study explores one avenue of potential language shift under the verticalization model and aims to gauge external influences on this one particular community-controlled institution. By assessing advertising language in two parallel publications, external and internal community influences should be visible over time. If external factors are attributing to a shift of the print language from the community-dominant language (which is non-dominant in broader society) to the dominant language, this should be evidenced in an increase of advertisements in the non-dominant community language. However, the results indicate that at a time where verticalization processes are changing the publishing landscape in other areas of the Midwest, in Eureka, South Dakota, the opposite appears to be true. The community-dominant language, German, sees an increase in advertisements published in German and a decrease in those published in English.

ABSTRACT Objective: to identify factors that lead the teacher to experience violence in their pedagogical practice in health education. Method: research with a qualitative approach, based on the Grounded Theory, conducted with 11 professors of the nursing course of a public university in the central region of Brazil in 2020 and 2021. Online semi-structured interviews were analyzed partially in the light of the Constructivist Grounded Theory. Results: factors that lead lecturer to experience violence are characterized by institutional culture, gender, professor’s perception of violence, and the triggers that drive students to commit violence. Social status and inequalities lead to positions of domination and, consequently, create a fertile ground for violence. Final Considerations: analyzing violence under Bourdieu’s theory, it is clear that student violence towards lecturer and the reports contained in this study deserve pedagogical reflection. However, it is necessary to include these discussions as a background in teaching environments.

Abstract Objective: To investigate vascular and perivascular abnormalities in the carotid arteries using ultrasound, as well as to evaluate their association with mortality and clinical variables in hospitalized patients with coronavirus disease 2019 (COVID-19). Materials and Methods: This was a prospective study in which 53 hospitalized patients with severe COVID-19 were evaluated and underwent carotid ultrasound. We documented the carotid ultrasound findings in these patients. Clinical, demographic, laboratory, and imaging features were analyzed and compared by statistical analysis to detect correlations between them. Results: Carotid ultrasound demonstrated luminal surface irregularity in 29 patients (55%), carotid plaques in 30 (57%), perivascular infiltration in four (8%), and increased intima–media thickness (IMT) in 31 (58%). Of the 31 patients with increased IMT, 19 (61%) died, and the association between increased IMT and COVID-19–related mortality was significant (p = 0.03). Logistic regression showed that the risk of death was 85% in patients who had increased IMT in combination with acute kidney injury at admission or a history of chronic kidney disease (p < 0.05). Conclusion: In hospitalized patients with severe COVID-19, carotid ultrasound can show increased IMT, luminal surface irregularity, carotid plaques, and perivascular infiltrates. The combination of increased IMT and kidney damage appears to increase the risk of death in such patients.

ABSTRACT This paper presents a systematic literature review, grounded on bibliometric procedures, of the (political economy) works, produced from 2008 to 2020, on the relations between Artificial Intelligence and employment. It detects a growing tendency of published papers in this field, especially from 2019, and identifies four main groups of concerns on this topic. Within these groups, a prevalence of more optimistic over skeptical accounts and, especially, of economic orthodox over heterodox approaches on the issue can be noted. Overall, it is possible to understand that both the reviewed works and their metrics are quite dispersed and varied in scope. Among other reasons, this is due to the lack of a common basic definition, within the field, of AI in the first place.

Published: December 2022

Resumo: Nas práticas de gestoras de secretarias municipais da Política de Assistência Social com formação em Serviço Social, observam-se dimensões de sexo, profissão e Política Social. O artigo objetiva analisar ações dessas secretarias no estado do Pará, considerando experiências de assistentes sociais gestoras no período de 1997-2020. Apesar das mudanças nessa Política e nas diretrizes formativas do Serviço Social, a atuação profissional permanece calcada nas contradições da Seguridade Social Brasileira.
PERSPECTIVAS DE FORMAÇÃO DE PROFESSORES NOS TRABALHOS DA FEIRA CATARINENSE DE MATEMÁTICA: UM OLHAR PARA A CATEGORIA PROFESSOR

Published: December 2022

RESUMO: A formação de professores no Brasil tem sido foco de interesse e pesquisas nas últimas décadas e tem contribuído para a compreensão e o avanço da área. Porém, quando seu direcionamento caminha para Feira de Matemática, tais pesquisas ainda são incipientes. Com vistas a contribuir para que este dado se modifique, o presente estudo é o resultado de uma pesquisa qualitativa centrada na problemática: que perspectivas de formação de professores podem se revelar a partir dos textos escritos decorrentes dos trabalhos apresentados na categoria Professor na Feira Catarinense de Matemática? Para isso, o corpus de análise foi constituído de 38 publicações registradas nos anais, relativas à categoria Professor, no tocante ao período de 2014 a 2019. A análise descritiva e interpretativa do corpus revelou que há distinta perspectivas de formação de professores: uma, em maior destaque, mais próxima da racionalidade prática; outra, mais relacionada à racionalidade crítica e, por fim, uma terceira relacionada à racionalidade técnica. Portanto, é possível evidenciar uma tendência dos professores expositores a relatarem práticas que buscam superar um ensino tradicional, valorizando destacadamente as ações oriundas de suas próprias experiências bem-sucedidas, mas também com vistas a algo advindo da práxis. Concluímos indicando a pertinência de discussões no âmbito da Feira acerca das implicações de cada uma das perspectivas de formação identificadas, bem como sugerindo problematizar a categoria Professor.
PELO DIREITO DE APRENDER: CONTRIBUIÇÕES DO MODELO SOCIAL DA DEFICIÊNCIA À INCLUSÃO ESCOLAR
Authors: PICCOLO GUSTAVO MARTINS
Published: December 2022

RESUMO: O presente artigo teórico, configurado a partir de um processo de revisão literária integrativa, realiza uma defesa inarredável do conceito da inclusão, tida como angular, a produção de uma prática educativa democrática e libertária. Contesta frontalmente o Decreto Presidencial n. 10.502, de 30 de setembro de 2020, suspenso temporariamente e que institui a nova Política Nacional de Educação Especial, por entender que o mesmo se escora em uma ideia frágil de inclusão como adstrita a presença dos estudantes com deficiência nas salas de aula regulares, sem tomar em nota as profundas e inadiáveis transformações que o suposto inclusivo denota no sentido de possibilitar a todos, aprendizagens satisfatórias com vistas a participação paritária em sociedade. O escopo teórico que baliza as linhas críticas aqui estabelecidas, refere-se à literatura convencionalmente chamada de modelo social da deficiência, a qual tem por ideia central, o entendimento da deficiência sob o prisma da produção histórica e sob a perspectiva de que a pessoa com deficiência não se reduz ao seu déficit. Os textos utilizados neste artigo tomam este suposto como força motriz ao visualizar na experiência da deficiência infindáveis possiblidades educacionais as quais permitem enriquecer e complexificar o desenvolvimento humano e as maneiras de intervenção em relação ao meio que nos circunda, a partir de plataformas originais que exercem impacto positivo em toda a coletividade. Vincula tais relações nos ambientes escolares à existência de adequações curriculares, reconfigurações didáticas, construção de espaços acessíveis e à transformação do próprio significado pelo qual a deficiência é concebida no terreno escolar.
