Published: August 2024

Several vaccines against chikungunya fever have been developed and tested, and one has been recently licensed. We performed a meta-analysis to estimate the immunogenicity and safety of all chikungunya vaccines that have been progressed to clinical trial evaluation (VLA1553; mRNA-1388/VAL-181388; PXVX0317/VRC-CHKVLP059-00-VP; ChAdOx1 Chik; MV-CHIK). We included trials retrieved from MedLine, Scopus, and ClinicalTrials.gov. The outcomes were the rates of seroconversion/seroresponse and serious adverse events (SAEs) after the primary immunization course. We retrieved a total of 14 datasets, including >4000 participants. All candidate chikungunya vaccines were able to elicit an immunogenic response in ≥96% of vaccinated subjects, regardless of the vaccination schedule and platform used, and the seroconversion/seroresponse rates remained high 6 to 12 months after vaccination for most vaccines. Four of the five candidate vaccines showed a good overall safety profile (no data were available for ChAdOx1 Chik), with no significant increase in the risk of SAEs among the vaccinated, and a low absolute risk of product-related SAEs. Overall, the present findings support the potential use of the candidate vaccines for the prevention of chikungunya and the current indication for use in adult travelers to endemic regions of the licensed VLA 1553 vaccine. In order to extend chikungunya vaccination to a wider audience, further studies are needed on individuals from endemic countries and frail populations.
The CornerGuard: Seeing around Corners to Prevent Broadside Collisions
Authors: Xu Victor , Xu Sheng
Published: August 2024

Nearly 3700 people are killed in broadside collisions in the U.S. every year. To reduce broadside collisions, we created and tested the CornerGuard, a prototype system that senses around a corner to alert a car driver of an impending collision with a pedestrian or automobile that is not in the line of sight (LOS). The CornerGuard leverages a microwave-transceiving radar sensor mounted on the car and a curved radio wave reflector installed at the corner to sense around the corner and detect a broadside collision threat. The car’s speed is constantly read by an onboard diagnostics (OBD) system to allow the sensor to differentiate between static objects and objects approaching around the corner. Field testing demonstrated that the CornerGuard can effectively and consistently detect threats at a consistent range without blind spots under broad weather conditions. Our proof of concept study shows that the CornerGuard can be enhanced to be readily integrated into automobile construction and street infrastructure.

Published: August 2024

Subacute ruminal acidosis (SARA) is a prevalent metabolic disorder in highly productive dairy cows that results in serious issues, including hoof lamellar injuries. This study aimed to investigate the efficacy of a carbonate buffer mixture (CBM) in preventing hoof lamella injury in dairy goats, a species also susceptible to SARA due to similar feeding practices over a 17-week period. Twenty-four healthy dairy goats were randomly assigned to three groups: control, SARA, and CBM groups. The control group received a standardized diet, whereas the SARA and CBM groups were subjected to a high-grain feeding regimen to induce SARA. The CBM group received a daily supplement of 10 g CBM mixed with their diet. Clinical assessments, including body temperature, rumen pH, inflammatory markers, matrix metalloproteinases (MMPs), and hoof lamellar injuries, were monitored throughout the study. The results showed that the CBM group maintained a more stable rumen pH and had lower levels of inflammatory markers than the SARA group did. The incidence of hoof lamellar injury was slightly lower in the CBM group. These findings suggest that long-term CBM supplementation may mitigate SARA-associated hoof lamella injury in dairy goats by regulating the rumen environment, fostering the growth of healthy bacterial communities, and by reducing the production of harmful metabolites. The use of CBM as a dietary supplement may have significant implications in improving the health, welfare, and productivity of dairy animals.

Published: August 2024

High-Static-Low-Dynamic Stiffness (HSLDS) mechanisms exploit nonlinear kinematics to improve the effectiveness of isolators, preserving controlled static deflections while maintaining low natural frequencies. Although extensively studied under harmonic base excitation, there are still few applications considering real seismic signals and little experimental evidence of real-world performance. This study experimentally demonstrates the beneficial effects of HSLDS isolators over linear ones in reducing the vibrations transmitted to the suspended mass under near-fault earthquakes. A tripod mechanism isolator is presented, and a lumped parameter model is formulated considering a piecewise nonlinear–linear stiffness, with dissipation taken into account through viscous and dry friction forces. Experimental shake table tests are conducted considering harmonic base motion to evaluate the isolator transmissibility in the vertical direction. Excellent agreement is observed when comparing the model to the experimental measurements. Finally, the behavior of the isolator is investigated under earthquake inputs, and results are presented using vertical acceleration time histories and spectra, demonstrating the vibration reduction provided by the nonlinear isolator.

Published: August 2024

Human activities play a key role in landscape evolution. Mining is one of the most important of these since it changes large parts of the Earth’s surface. In abandoned mines and quarries, pit lakes are quite common due to water table blocking. These lakes have remarkable ecological characteristics, but they are still poorly understood. Northwestern Spain has a long tradition in the use of slate for roofs. This exploitation, mostly open-pit, has caused a great transformation in the landscape including the generation of pit lakes. In this work, 27 pit lakes in abandoned slate quarries areas have been analysed using orthophotos of different years, UAV (unmanned aerial vehicle) images and field work. In each lake, the topographic context, geomorphological dynamics, morphometric parameters (including depth), pH, and ecological variables were measured. Other uses for these quarry pit lakes and their significance as a new geo-ecological environment are also discussed. The results show different types of pit lakes and, consequently, different potential uses in each case. Only six offer good conditions for recreational uses, whereas the rest (21) show slope instability or poor water quality.

Published: August 2024

Peracetic acid (PAA) has attracted increasing attention in wastewater decontamination for yielding reactive oxygen species (ROS). In this study, mackinawite (FeS) was synthesized and applied as the heterogeneous catalyst for PAA activation. Using sulfamethoxazole (SMX) as the target pollutant, the influences of FeS dosage, PAA dosage and initial pH values on SMX degradation by the FeS/PAA process were investigated. Under optimal conditions, SMX could be completely removed within 5 min with the apparent first-order rate constant (kobs) of 7.71 × 10−4 s−1. Electron spin resonance spectroscopy (ESR) analysis and radical scavenging experiments were modulated to detect the active species. During the activation process of PAA, various active components were evidenced to be hydroxyl radicals (HO•), singlet oxygen (1O2), superoxide radicals (O2•−) and organic radicals (R-O•, e.g., CH3C(O)O• and CH3C(O)OO•), whereas HO• and R-O• were demonstrated as the dominant active species responsible for SMX abatement. Both dissolved Fe(II) ions and active sites on the surface of FeS were proven to be activators for PAA, and SMX abatement was highly promoted as a result. Furthermore, the acidic pH displayed superior efficiency in SMX decomposition compared with alkaline and neutral conditions. Five degradation pathways of SMX were put forward and the toxicity of byproducts was further evaluated. Overall, this study provided an efficient and environmentally friendly PAA activation approach using FeS, which might broaden its applicability in the remediation of micropollutants.

Published: August 2024

There has been a frequent occurrence of tailing dam failures in recent years, leading to severe repercussions. Flood overtopping is an important element contributing to these failures. Nevertheless, there is a scarcity of studies about the evolutionary mechanisms of dam breaches resulting from flood overtopping. In order to fill this knowledge vacuum, this study focused on the evolutionary characteristics and triggering mechanisms of overtopping failures, utilizing the Heshangyu tailings pond as a prototype. The process of overtopping breach evolution was revealed by the conduction of small-scale model testing. A scaled-down replica of the tailings pond was constructed at a ratio of 1:150, and a controlled experiment was conducted to simulate a breach in the dam caused by water overflowing. Based on the results, the following conclusions were drawn: (1) The rise in water level in the pond caused the tailings to become saturated, leading to liquefaction flow and local slope sliding at the initial dam. If the sediment-carrying capacity of the overflowing water exceeded the shear strength of the tailings, water erosion would accelerate landslides on the slope, generating a sand-laden water flow. (2) The breach was primarily influenced by water erosion, which subsequently resulted in both laterally widened and longitudinally deepened breach. As the breach expanded, the sand-carrying capacity of the water flow increased, leading to a faster rate of failure. The breach process of overtopping can be categorized into four distinct stages: gully formation stage, lateral broadening stage of gully, cracks and collapse on the slope surface, and stable stage of collapse. (3) The tailings from the outflow spread downstream in a radial pattern, forming an alluvial fan. Additionally, the depth of the deposited mud first increased and subsequently declined as the distance from the breach grew. The findings of this research provide an important basis for the prevention and control of tailings dam breach disasters due to overtopping.

Published: August 2024

Accurate and timely information on building age is essential for mitigating the impacts of natural disasters such as earthquakes and floods. Traditional methods for collecting these data are often inefficient and costly. This study leverages remote sensing and machine learning to classify building age and integrate this information into a comprehensive flood hazard map for Al Ain City. By combining building age with elevation, topography, land use, population density, and other factors, we generated a flood hazard map that effectively identifies high-risk areas. Our results show that a significant portion of the city is has low potential for flooding (61%), while others face moderate (32%), high, or very high flood hazards. This study provides crucial information for informed decision-making regarding future urban planning, disaster management, and development strategies in Al Ain City. By identifying vulnerable buildings in advance, it supports efforts to reduce disaster risks, protect lives, and optimize resource allocation.
Intrusion Event Classification of a Drainage Tunnel Based on Principal Component Analysis and Neural Networking
Authors: Yuan Peng , Zhang Weihao , Shang Xueyi , Pu Yuanyuan
Published: August 2024

Drainage tunnel stability is crucial for engineering project safety (e.g., mine engineering and dams), and rockfall events and water release are key indicators of drainage tunnel stability. To address this, we developed a monitoring system to simulate drainage tunnel intrusions based on distributed acoustic sensing (DAS), and we obtained typical characteristics of events like rockfall events and water release. Given the multitude of DAS signal feature parameters and challenges, such as high-dimensional features impacting the classification accuracy of machine learning, we proposed an identification method for drainage tunnel intrusion events using principal component analysis (PCA) and neural networks. PCA reveals that amplitude-related parameters—amplitude, mean amplitude, and energy—significantly contribute to DAS signal classification, reducing the feature parameter dimensions by 54.8%. The accuracy of intrusion event classification improves with PCA-processed data compared to unprocessed data, with overall accuracy rates of 79.1% for rockfall events and 72.7% for water release events. Additionally, the artificial neural network model outperforms the Bayesian and logistic regression models, demonstrating that ANN has advantages in handling complex models for intrusion event classification.

Published: August 2024

Studies covering key elements of the marine ecosystem based on current and long-term data have made it possible to assess both the current situation in terms of copper concentrations in commercially used fish and benthic plants and in surface bottom sediments, as well as enabled the analysis of the temporal variability of copper levels in relation to changes in its inflow to the southern Baltic Sea. By applying the threshold values, determining the boundary between good and not good status of the marine environment, set in this study, it was found that good environmental status has been achieved in the case of Cu in seawater and plants and has not been achieved in the case of sediments and fish for consumption. The study showed that climate change, the main feature of which is an increase in seawater temperature, significantly impacts the distribution and levels of copper in individual elements of the marine environment. It influences the vegetative season length and bioaccumulation efficiency and is of key importance for copper toxicity.

Published: August 2024

As climate change and decreasing precipitation worsen water scarcity, understanding farmers’ willingness to reduce water usage is crucial. This study examines this issue in the Aosta Valley, a region facing unique challenges due to its mountainous terrain and high water management costs. The aim is to evaluate farmers’ willingness to reduce water usage and the economic incentives needed to encourage water-saving strategies. To gather the data, 100 farmers participated in a survey that included a discrete choice experiment. The findings revealed that 75% of farmers were unwilling to reduce their water usage even with proposed monetary compensation (EUR 100–120 per hectare per year). On average, the additional compensation farmers would accept for a 10% reduction in water usage was estimated at EUR 360 per hectare per year. This high compensation demand suggests a disconnect between individual desires and economic feasibility. The key reasons for their reluctance included the belief that their current water usage is already optimized, inadequate compensation for potential economic losses and concerns about water shortage. The study highlights the need to understand the socio-cultural context when designing water management policies. Combining economic incentives with social and educational initiatives is likely more effective for promoting sustainable water practices.

The current absence of well-established and standardized methods for characterizing submicrometer- and nano-sized particles in water samples presents a significant analytical challenge. With the increasing utilization of nanomaterials, the potential for unintended exposure escalates. The widespread and persistent pollution of water by micro- and nanoplastics globally is a concern that demands attention, not only to reduce pollution but also to develop methods for analyzing these pollutants. Additionally, the analysis of naturally occurring nano entities such as bubbles and colloidal matter poses challenges due to the lack of systematic and consistent methodologies. This study presents Asymmetric Flow Field-Flow Fractionation (AF4) separation coupled with a UV-VIS spectrometer followed by Multi-Angle Light Scattering (MALS) for detection and size characterization of nanometric entities. It is coupled with an Inductively Coupled Plasma Mass Spectrometer (ICP-MS) for elemental analysis. Water samples from different sources, such as untreated mountain spring water, groundwater, and bottled drinking water, were analyzed. The system was calibrated using pure particle standards of different metallic compositions. Our study demonstrates the capability of AF4-UV-MALS-ICP-MS to detect metals such as Al, Ba, Cu, and Zn in particles of around 200 nm diameter and Mg associated with very small particles between 1.5 and 10 nm in different drinking water samples.

Published: August 2024

As mining engineering progresses into the deep excavation phase, the intensification of high pressure, high temperature, strong disturbances, and complex geological conditions becomes increasingly prominent. Researchers perform stability analysis on the excavation area to reduce potential safety hazards during the extraction process. Developing a detailed numerical calculation model that accurately reflects the true geological structure is essential for numerical simulation analysis in mining engineering. Based on the excellent 3D geological modeling capabilities of 3D Mine software, this paper introduces a new 3D geological and numerical unified modeling method (3DMine-Rhino-HyperMesh) involving multi-software coupling and details the specific steps and concepts of this modeling approach. Subsequently, using a certain open-pit mine in Panzhihua as a backdrop, a detailed geological and numerical unified model is established, reflecting the true geological structure of the mining area, and the potential failure mechanisms of the mine slope are analyzed. The results indicate that the modeling method aligns well with the actual geological conditions, enhancing the grid quality of the numerical model and offering a new modeling approach for simulating and analyzing large complex geological entities in mining operations.

Published: August 2024

This study attempts to overcome the challenges associated with the degradation of complex organic substances like corn straw hydrolysate in hydrogen recovery by strategically enriching functional microbial communities in single-chamber cubic microbial electrolysis cells (MECs). We applied negative pressure, using acetate or xylose as electron donors, to mitigate the hydrogen sink issues caused by methanogens. This innovative method significantly enhanced MEC performance. MECs enriched with xylose demonstrated superior performance, achieving a hydrogen production rate 3.5 times higher than that achieved by those enriched with acetate. Under negative pressure, hydrogen production in N-XyHy10 reached 0.912 ± 0.08 LH2/L MEC/D, which was 6.7 times higher than in the passive-pressure MECs (XyHy10). This advancement also resulted in substantial increases in current density (73%), energy efficiency (800%), and overall energy efficiency (540%) compared with MECs operated under passive pressure with 10% hydrolysate feed. The enrichment of polysaccharide-degrading bacteria such as Citrobacter and Pseudomonas under negative pressure underscores the potential for their industrial application in harnessing complex organic substrates for bioenergy production in single-chamber MECs. This is a promising approach to scaling up bioenergy recovery processes. The findings of this research study contribute significantly to the field by demonstrating the efficacy of negative pressure in enhancing microbial activity and energy recovery, thereby offering a promising strategy for improving bioenergy production efficiency in industries.

Published: August 2024

Purpose: To analyze adenoma detection rate (ADR) and related quality indicators of colonoscopy among trainees and make recommendations for appropriate colonoscopy training.Methods: ADR and related indicators of colonoscopies performed by 3 trainees and 5 colonoscopy experts between March and November 2022 were analyzed. These indicators were analyzed in both the entire patients and the screening/surveillance group. In addition, the training period of the 3 trainees was divided into 3 sections, and the changes in these indicators were examined.Results: The mean ADR of the 3 trainees was 50.6%. In the screening/surveillance group, the mean ADR of the 3 trainees was 51.8%, showing no significant difference from the experts' ADR (53.4%). When the training period was divided into 3 sections and analyzed in the screening/surveillance group, the mean ADR of the trainees gradually increased to 49.4%, 52.6%, and 53.6%, respectively; however, the difference was insignificant. Analyzing each trainee’s ADR, there was a significant difference among the 3 trainees (58.5% vs. 44.7% vs. 50.2%, P=0.008). However, in the third section of the training period, the 3 trainees’ ADRs were 53.0%, 49.2%, and 57.3%, respectively, showing no significant difference (P=0.606).Conclusion: In the early stages of training, the ADR was higher than recommended; however, there were variances in ADR between individuals. As the training period passed, the ADR became similar at the expert level, whereas the difference in ADR between trainees decreased. Therefore, efforts to increase ADR should be made actively from the beginning of training and continued during the training period.

Authors: Leach Helen , Eccles Abi , Chew-Graham Carolyn A , Atherton Helen
Published: August 2024

Background

Remote and digital consulting in primary care has rapidly expanded since March 2020. It is important to understand patient experiences, particularly for those living with complex long-term conditions, to identify how care can best be delivered, including within the remote space.

Aim

To explore the experiences of people living with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and fibromyalgia when consulting remotely in primary care.

Design & setting

Semi-structured interviews with patients living with CFS/ME and fibromyalgia in general practice in England.

Method

Semi-structured interviews were carried out with 13 participants. The interviews were transcribed and analysed thematically according to a Foucauldian theoretical framework.

Results

All participants highlighted needing to feel believed by clinicians. Many reported difficulties with telephone and online consulting owing to the lack of physical communication. Positive outcomes were reported when there was a good relationship with a clinician. Continuity in care and recognising the complexity of these conditions were also considered important.

Conclusion

This study allowed people living with CFS/ME and fibromyalgia to describe their experiences when consulting remotely. Participants highlighted needing to feel listened to and felt they benefited from an ongoing relationship with a clinician although this was difficult to achieve when consulting remotely. Some advantages of remote consulting were reported, particularly when symptoms were troublesome. Flexible access systems, with a range of consultation modalities or preferred clinician(s) availability, could improve healthcare encounters, particularly given the increased use of remote consulting in primary care.

O conceito de deficiência tem sofrido muitos deslocamentos ao longo do tempo – uma vez que determinados diagnósticos, a cada mudança legal, passam a ser incorporados à categoria, ou descolados dela, e disso decorre uma série de efeitos. Um deles diz respeito às condições especiais oferecidas na realização dos vestibulares – apoios para permitir formas igualitárias de acesso ao ensino superior – voltadas às pessoas cujas corporeidades demandam adaptações. Dos diagnósticos mais comuns no ambiente educacional, inclusive no ensino superior, o Transtorno do Déficit de Atenção e Hiperatividade (TDAH) se destaca – e passa a constar no rol daqueles que propiciam condições diferenciadas nos processos seletivos, ainda que não seja um tipo de deficiência. Por meio da análise dos discursos que se constroem em torno do ingresso de pessoas com a condição supramencionada, considerando duas Universidades Federais do Sul do Brasil, a intenção é compreender, partindo de uma perspectiva foucaultiana de análise, quem de fato está sendo incluído e quais narrativas – sobre a desatenção/impulsividade/hiperatividade – têm sido construídas para respaldar as condições diferenciadas de acesso, e também permanência, a esse grupo.
Do discurso à prática: um estudo da política em educação em Minas Gerais
Authors: Vieira Ednando Batista , Amorim Inara Rosa de
Published: August 2024

Este trabalho discute a efetividade das políticas públicas voltadas à educação em Minas Gerais, em contraponto com as perspectivas e promessas apresentadas pelos candidatos em anos eleitorais. Para isso, realizou-se uma análise estatística multivariada, com dados do INEP, sobre a estrutura educacional das escolas mineiras. Dentre as variáveis, analisamos, especificamente, aquelas referentes à quantidade de alunos beneficiados e a qualidade do ambiente escolar. O que verificamos, de uma forma geral, foi a presença de disparidade evidente entre o discurso político e os resultados concretos, corroborada pelo nível de desigualdade muito grande, com elevados coeficientes de variação entre as regiões analisadas.

O objetivo deste artigo é oferecer elementos a docentes e pesquisadores/as que permitam trabalhar as sexualidades divergentes em contextos indígenas em contextos educacionais. Dessa forma, apresentam-se questões-chave para melhor compreender o tema, tais como a denominação, a abordagem e a colonização das sexualidades indígenas no Brasil. Ao final, são apresentados temas-geradores para o desenvolvimento e aprofundamento do problema, à luz de questões que transcendem o universo indígena, mas que dialogam com os processos coloniais.

Este estudo objetiva compreender, a partir da perspectiva dos alunos do Curso de Pedagogia da Universidade do estado do Rio Grande do Norte - UERN, como os professores formadores dos estágios supervisionados, contribuem para sua formação. É um estudo de abordagem qualitativa. A investigação se concretizou por meio de entrevista narrativa, direcionada a dezenove alunos do 8º período do referido curso. A interpretação dos dados se ancorou na análise do discurso e foram construídas a partir de estudo bibliográfico, além de documentos oficiais da instituição investigada, como: o Projeto Pedagógico do Curso de Pedagogia (PPCP) e o Programa Geral do Componente Curricular (PGCC) das disciplinas dos estágios supervisionados. Mediante os resultados, inferimos que os professores formadores dos estágios supervisionados, contribuem positivamente para a formação dos alunos. Entretanto, foram identificadas algumas dificuldades relacionadas ao desenvolvimento do estágio, fator que revela a necessidade de refletir sobre uma possível reformulação do currículo do curso analisado.

Compreende-se como seminário escolar um evento de letramento (VIEIRA, 2007) que se constitui a partir de três etapas: 1) planejamento; 2) execução; 3) debate e avaliação. Em cada uma dessas etapas, ocorrem atividades diversas, organizadas a partir de gêneros textuais variados. No presente artigo, focalizamos a etapa de execução de seminários em contexto de Ensino Médio, mais particularmente o gênero exposição oral. O objetivo é propor reflexões relativas a estratégias didático-discursivas mobilizadas para esse gênero (MATENCIO, 2001), de modo a compreender concepções e procedimentos envolvidos no evento seminário, a partir de contribuições teóricas de Marcuschi (2001); Schneuwly (2004); Dolz et al. (2004), entre outros. O corpus é composto por seis exposições orais produzidas com base em uma sequência didática, que foram videogravadas e, posteriormente, transcritas conforme normas específicas (PRETI, 1999) para fins de análise, de natureza descritiva-interpretativa. Os resultados indicam principalmente: a) percepção de etapas que constituem o seminário; b) apropriação do objetivo da atividade. Por um lado, observamos possíveis contribuições de um ensino-aprendizagem que considere dimensões da oralidade do evento e do gênero-alvo. Por outro, revelam-se ainda práticas relativas à concepção de seminário como uma apresentação oral elaborada a partir da soma de “partes” divididas entre os membros.
ITÁLIA, EUA E BRASIL NA PANDEMIA
Authors: Takeuchi Nozaki Hajime , Gonçalves de Freitas Rogério
Published: August 2024

O ano de 2020 foi marcado por um fenômeno jamais visto em escala global, a pandemia ocasionada pelo Novo Coronavírus, o SARS-COV2. O mundo inteiro presenciou a assustadora velocidade de propagação do vírus, o qual trouxe difíceis consequências do ponto de vista econômico, social, sanitário e educacional para diversas sociedades.
O dossiê que ora apresentamos denominado Itália, EUA e Brasil na pandemia: desdobramentos no campo educacional, redigido por autores que acompanharam in loco o fenômeno em três dos principais países com consequências severas e alta taxa de mortalidade, parte do posicionamento de que a crise sanitária tem raízes mais profundas calcadas no modo de produção da vida das sociedades capitalistas.
CRISE ECONÔMICA PANDÊMICA E GLOBAL
Authors: Tapia José , Nozaki Hajime Takeuchi
Published: August 2024

É impossível saber se uma crise econômica global teria ocorrido em 2020 sem a pandemia COVID-19, embora muitos dados sugiram isso. Também não é possível prever em que medida essa crise afetará cada país, quanto tempo ela vai durar e até que ponto o provável declínio da pandemia será capaz de reativar a economia em 2021. Em 2020, houve contrações significativas no Produto Interno Bruto (PIB) em muitos países (por exemplo, nos EUA 3,5%, no Japão 5,3%, na Índia 10,2%, na Rússia 3,1%); na China, o PIB cresceu a uma taxa minúscula (2,3%) em relação aos anos anteriores. Tudo isso mostra esta crise como aquela sem precedentes desde a Grande Depressão de 1929. Resta saber se a economia reagirá ao estímulo de trilhões de dólares aprovados nos Estados Unidos, de um tamanho muito grande em comparação com os gastos públicos em outras ocasiões, ou se entrará em uma crise inflacionária como temem alguns economistas. A crise econômica associada à pandemia tem características únicas e as previsões econômicas, sempre arriscadas, nesta ocasião o são ainda mais. O primeiro ano da pandemia mostrou que a infecção afeta mais os homens do que as mulheres e é mais provável que seja fatal quanto mais velho o paciente é e quando há doenças crônicas pré-existentes. Como essas doenças têm um gradiente social e, uma vez que o COVID-19 afeta menos aqueles com maior nível de renda e que vivem menos aglomerados, ou com melhores empregos que permitem teletrabalho, a mortalidade pandêmica também tem um gradiente por classe social e grupo étnico e, portanto, nos EUA a mortalidade tem sido significativamente maior entre afro-americanos, latinos e a população ameríndia. Com diferenças provavelmente não muito importantes entre os países, a taxa de letalidade, ou seja, a proporção daqueles que morrem e aqueles que adoecem será quanto menor o nível de renda dos pacientes, e assim a pandemia contribuirá para a manutenção e aumento das desigualdades na saúde. As vacinas estão sendo distribuídas no mundo basicamente de acordo com a capacidade de pagamento dos países e de cada país o favoritismo e as conexões muitas vezes prevalecem na vacinação sobre o critério epidemiológico para minimizar as mortes. Se uma coisa é clara entre as muitas incógnitas que o momento atual levanta, é a necessidade de apoiar aqueles que abrem alguma perspectiva para o futuro, sejam os manifestantes pró-democracia de Mianmar ou Hong Kong, os agricultores lutando por sua sobrevivência contra os grandes interesses comerciais na Índia, ou aqueles que protestam contra o racismo, a repressão, corrupção e os abusos governamentais ou policiais na Rússia, na Nigéria, na Nicarágua, no Paraguai, nos Estados Unidos ou em qualquer país do mundo.

Published: August 2024

O artigo analisa as possibilidades de efetivação da legislação para a educação especial no Brasil, a partir do texto do Plano Nacional de Educação (2014-2024). Discute a constituição histórica da educação especial como modalidade projetando os desafios de sua oferta no ensino regular. Tem como suporte de análise a teoria crítica, que evidencia a relação entre Estado, sociedade civil e terceiro setor como vínculo real, em que a problemática da garantia dos direitos se desenvolve. Utiliza revisão da bibliografia sobre o tema. Objetiva compreender os desafios da efetivação da educação para alunos com deficiência e transtornos globais do desenvolvimento, altas habilidades e superdotação, em uma dinâmica social organizada a partir da lógica de mercado.
