Is the association of physical activity with mental burden mediated by quality of life? A cross-sectional study with undergraduate students
Authors: Silva Michael Pereira da , Matias Thiago Souza , Demenech Lauro Miranda , Dumith Samuel Carvalho
Published: December 2024

Background
The literature lacks studies investigating the role of quality of life in the relationship between physical activity and mental health. The objectives were: i) to analyze the association of physical activity with mental burden among college students and ii) to determine whether the domains of quality of life mediate the association between physical activity and mental burden.
Methods
A cross-sectional study with a random sample of undergraduate students from southern Brazil was conducted. The data collection was carried out in 2019 using self-administered questionnaires. Depression, anxiety, and stress outcomes were clustered, resulting in three clusters (very high, high, and low risk of mental burden). A general structural equation model was used to examine mediation.
Results
This study analyzed data from 766 individuals (66% of the eligible sample). The prevalence of active individuals (150 min/wk or more) was 2.5-fold greater for cluster 3 of mental burden (lower risk) compared to cluster 1 (higher risk). The physical and psychological domains of quality of life mediated the association between physical activity and mental burden.
Conclusion
Physical activity had a protective effect on mental burden, partially mediated by physical and psychological domains of quality of life.
Recent Advancements in Grad-CAM and variants: Enhancing Brain Tumor Detection, Segmentation, and Classification
Authors: Kumar Krishan , Jyoti Kiran
Published: December 2024

Brain tumors, caused by abnormal tissue growth in the brain, can significantly impair brain functions and pose significant health risks. As the tumor progresses to higher stages, the patient's prognosis and survival decline, resulting in a high mortality rate. With advances in medical imaging, particularly the use of MRI, AI approaches have emerged as powerful tools for detecting, segmenting, and classifying brain tumors. CNN and hybrid models such as Vision Transformers (ViTs) have provided promising insights in this area. Despite their high accuracy, but the reasoning behind the prediction often remained unanswered. AI models lack transparency and interpretability, paving the way for the development of explainable AI methods in diagnosing brain diseases. In recent years, gradient weighted class activation mapping (Grad-CAM) and its variants have emerged as powerful techniques for visualizing and interpreting deep learning models in medical imaging tasks, including brain tumor detection, segmentation, and classification. This paper provides a comprehensive overview of Grad-CAM and its improvements, with particular emphasis on their applications in brain tumor analysis. In this article, we reviewed the 31 research papers based on data from various research databases. This review highlights the importance of interpretability in deep learning for clinical applications and explores how Grad-CAM can complement traditional metrics to provide deeper insights into model decisions. The results provide valuable guidance for researchers developing explainable AI frameworks for accelerating brain tumor analysis, with the objective of developing trust, efficiency and clinical utility in resource-limited settings.

Published: December 2024

Weakly supervised semantic segmentation can significantly alleviate the annotation burden of the pixel-level collection used in full supervision. However, most existing works are based on simple images and only include a few tags, which are not applicable to free-space segmentation under complex driving scenes. In this study, we develop an effective weakly supervised framework with image-level label for free-space segmentation by incorporating the spatial priors with geometric context of road. The proposed method jointly leverages the locating capability of image tags and low-level structure information of superpixels, and fuses spatial weights and superpixel region features by a region-based clustering method. These strategies guarantee the satisfying segmentation results while facing the complex driving scenes. Extensive experimental results on the Cityscapes datasets show that our work outperforms some competing weakly supervised methods in terms of intersection over union (IoU), and is a feasible way to perform free-space segmentation in complex environments for auto-driving application.

Published: December 2024

Ensuring fair and transparent elections is reliant on the authenticity of voters and the purity of ballots cast. This paper discusses the way that double voting and fraudulently verifying voters can be solved with biometric technologies incorporated together with machine learning. To do this, a dual authentication system is proposed which uses a fingerprint sensor for utmost accuracy during identification, coupled with face recognition in order to minimize instances of dual registration in traditional (Electronic Voting Machine) EVM. The system continuously checks the identities of individual voters while relaying the details of their verification process to a central control unit; this increases both effectiveness and safety. Besides, this research develops as well as tests algorithms of machine learning where Neural Networks (NN) are used to estimate turnout percentages. In addition, techniques associated to data pre-processing have been utilized in order to improve accuracy. Consequently, it shows how proposed NN based models work when predicting voting results hence contributing towards better secured and freer from any form manipulation polling systems.

Impact of repositioning errors on the aerodynamic performances in cycling
Authors: Foguenne Léonore , Schwartz Cédric , Andrianne Thomas
Published: December 2024

Aerodynamic drag is a significant force in cycling, especially at speeds above 40 km/h, where it can account for up to 90% of total resistance. Accurate aerodynamic assessment is essential for optimizing cycling performance through equipment and positional adjustments. However, traditional wind tunnel testing uses static models that fail to replicate the dynamic nature of actual cycling, limiting their ability to investigate biomechanical or physiological factors. This study quantifies the variability introduced by cyclists' repositioning during wind tunnel tests, compares it to drag differences from equipment changes, and evaluates the effectiveness of a real-time feedback system in reducing this variability. The study involved three phases: baseline helmet testing on a static mannequin, development of a position-tracking system, and wind tunnel testing with one amateur and one advanced cyclist. Differences in drag area (CDA) between aero-helmets were around 0.0032 m². Repositioning variability without feedback ranged from 0.003 m² to 0.072 m² for the amateur cyclist and from 0 m² to 0.020 m² for the advanced cyclist. Feedback reduced the amateur cyclist’s variability to 0.005 m² to 0.027 m², comparable to the advanced cyclist. However, feedback had limited effect on the advanced cyclist, with a drag variability of 0 m² to 0.013 m². These findings suggest that repositioning errors can overshadow aerodynamic gains from equipment, particularly for less experienced cyclists. While feedback helps reduce these errors, improved testing methods are needed to fully account for rider variability and optimize performance.

Published: December 2024

The global water crisis affects water quality and aquatic ecosystems leading to shifts in the structure of microbial community that can be used for monitoring environmental change. The current study aims to use eDNA metabarcoding to elucidate the structure and diversity of microbial communities along a pollution gradient in a tropical river. Sampling was carried out at four sites, along an anthropogenic disturbance gradient in Mexico City (Magdalena River). The results show clear differences in the composition of the prokaryotic and microeukaryotic communities between sites. Bacterial communities in sites with low to moderate disturbance were associated with nitrogen biogeochemical processes or plant-microbe interactions, while those in sites with moderate to high disturbance levels were associated with enteric, nosocomial, or fecal nature. Microbial communities in peri-urban sites had a greater diversity of phyla, while microeukaryotic communities decreased in the number of present phyla, as the gradient of human influence progresses, showing that 2 phyla together contribute with a relative abundance greater than 75% through the year. We propose that the characterization of the microbial community structure is better for identifying anthropogenic influences on lotic systems than the use of single species.
Team Virtue as a Predictor of Transactional Style
Authors: Sharma Santosh Kumar , Khan Imran Ahmed , Indiran Jayasri
Published: December 2024

In the history of organizational development, there was a time when performance of an individual employee was given significant weightage especially during performance appraisal. However, with the changing landscape of organizational dynamics, focus of performance measurement has been shifted from individual to team level. The possible reason for this tectonic shift is the evaluator’s mindset who work as a business leader most of the times and believes that if an employee is not able to work as a team member, his or her performance contribution can be neglected from the organizational perspective. With this backdrop, it is assumed in the present research paper that if an employee has any kind of team virtue, her or him transactional style can be predicted to a reasonable extent. Based on the predicted transactional style, some kind of training interventions can be applied especially in the areas like communication, team building and similar ones. Data has been collated through secondary (literature review) and primary sources (questionnaire-based survey). Based on correlational and regression analysis through SPSS (version 25), results have been discussed followed by conclusions and implications.
Enhancing Text Quality with Human-Machine Collaboration: A Refinement Approach
Authors: Sun Yicheng , Wang Yi , Yang Jianwei , Liu Tao , Yang Hanbo
Published: December 2024

Human writing often exhibits a range of styles and levels of sophistication. However, automated text generation systems typically lack the nuanced understanding required to produce refined and elegant prose. Due to the inherent one-to-many relationship between inputs and outputs in natural language generation tasks, achieving annotator consistency is challenging. This complexity makes the annotation process considerably more difficult compared to tasks focused on natural language understanding. Our study focuses on the typical task of text refinement, which faces annotation difficulties, aiming to generate sentences with more elegant expressions while preserving the original semantics of the input sentence. This paper proposes a semi-automatic data construction method that combines auto-generation with human judgment. Initially, this method translates collected sentences containing elegant expressions into ordinary expressions through back translation. Subsequently, in an iterative quality control process, data filtering and human judgment are introduced to screen the auto-generated data based on quality standards, resulting in a large-scale text refinement dataset. By replacing manual annotation with human judgment and involving only a small amount of data for human judgment in each iteration, this method significantly reduces annotation difficulty and workload. With minimal human effort, it acquires a substantial amount of labeled data for text refinement, laying a foundation for further research in the field.

Published: December 2024

The development of rechargeable lithium-ion batteries with high-strength density and long-cycle lifestyles is essential to address the growing demand for dense storage in various technology applications, including portable electronics, hybrid and electric vehicles, and power system. grid-scale energy storage. All of these must be sustainable electrochemically and generally robust. The main limitation in recognizing these functions is the lack of electrodes with excellent mechanical and electrochemical properties. CHs combine the electrical conductive properties of metals or semiconductors with the unique properties of hydrogels and are important for forming and assembling lithium ion battery electrodes. Which can contain a large amount of electrolyte solution in the conductive network of 3D nanostructures, providing a large number of sites on the surface for the required electrochemical reactions. Until now, 3D nanostructured CH has shown excellent performance when used as an electrode materials for LIBs. Future efforts are based on improving the intentional CH with controllable size, composition, shape, and interface. In this review, we focus on fabrication of CH, how conductive hydrogels are incorporated into the active materials (Si nanparticles, tin-metal alloy and transition metal oxides) of LIBs, and show some of the hydrogel electrode materials in LIBs based on Si, tin alloys and transition metal oxides based hydrogels.

Sehr oft werden Veränderungen des Politischen durch die Einflüsse Sozialer Medien erklärt: Ursächlich dafür seien Algorithmen, Fake News und eine durch die Jagd auf Likes veränderte Debattenkultur. Tatsächlich zeigen sich in Sozialen Medien Phänomene der sozialen Schließung oder des vermehrten politischen Extremismus‘. Wie sie entstehen, wird jedoch kaum gefragt. Genau das tut das 2021 erschienene Sammelwerk.
Es sind unter anderem Historiker*innen, Medienwissenschaftler*innen, Künstler*innen, Politik-, Literatur- und Kulturwissenschaftler*innen, Geograph*innen, Soziolog*innen und Sozialpädagog*innen, die mit Rückgriff auf empirisches Material ihre jeweils spezifische Perspektive auf das Forschungsfeld darstellen. So finden sich spannende Beiträge, die beispielsweise ‚Geschlechterstereotype in der propagandistischen Kommunikation‘ in den Fokus nehmen, den Zusammenhang zwischen ‚Kapitalismus, Körperdarstellung und sozialen Medien‘ untersuchen, oder die ‚Bedeutung des Bildhaften im strategischen Framing lokalen Protests am Beispiel einer Kleingartenkolonie‘ diskutieren.
Die Herausgeber*innen wollten mit diesem Band etwas schaffen, das nach eigener Aussage „in dieser Form Neuigkeitswert hat“ (S.8). Sie zielen auf eine methodologische Debatte ab, wie sie die Komplexität des Themas erfordert. Denn nicht Generalisierungen sind die Lösung. Sondern eine ‚Polyphonie‘ unterschiedlicher Forschungszugänge. Dieses Vorhaben ist gelungen.

Adaptability and Character Traits of Turf-type Tall Fescue Cultivars Grown under Limited Irrigation in Northern Italy
Authors: Novello Alberto , Pornaro Cristina , Fidanza Michael , Macolino Stefano
Published: December 2024

The use of tall fescue is increasing in the European transition zone because of its inherent tolerance to heat and drought stresses. Climate change, as expressed by more frequent drought occurrences, presents a challenge for selecting appropriate turfgrass cultivars. A field study was conducted at the Experimental Agricultural Farm of the University of Padova (Legnaro, Italy) to assess the response of 20 tall fescue cultivars grown without irrigation for 2 years (with a single emergency irrigation application in Jul 2022). The cultivars were evaluated every 2 weeks from Mar 2021 to Mar 2023 to determine the texture, uniformity, density, color, quality, green turf cover, and normalized difference vegetation index (NDVI). The cultivars tested were Bullseye, Darlington II, Detonate LS, Forlaine, Grande II, Lexington, Melya-ne, PPG-TF238, PPG-TF254, PPG-TF315, PPG-TF336, RGT Nuance, Rhambler SRP, Talladega II, Thor, Thunderstruck, Tough, Triad, Turfway, and ZRC-1. The results confirmed the ability of tall fescue species to tolerate drought stress as imposed within the parameters of this field study. For all cultivars, a slight decrease in quality was observed only in the summer of the second year under severe drought conditions. The inherent low cold tolerance of tall fescue compared with that of other cool-season species observed for all the study cultivars resulted in lower quality, color, and uniformity during the winter, but density was maintained throughout the entire study period. The best-performing cultivars based on quality, NDVI, and green turf cover were PPG-TF336, Triad, and ZRC-1. Therefore, tall fescue provides a sustainable solution for amenity turfgrass lawns in water deficit climates, and turf-type tall fescue cultivars with the desired characteristics of optimum quality and drought tolerance should be considered for lawns with the European transition zone.
Himalayan Leucogranites: Field Relationships and Tectonics
Authors: Searle Mike , Cottle John
Published: December 2024

Himalayan peraluminous leucogranites were derived from in-situ melting of sillimanite + K-feldspar-bearing pelite-migmatite, and were transported via layer-parallel sill complexes and cross-cutting dykes to feed giant sills up to 5 km thick. Partially melted Himalayan middle crust was extruded southwards between two large-scale, north-dipping, synchronous ductile shear zones: the Main Central Thrust (MCT) below and the low-angle normal fault South Tibetan Detachment (STD) above. U-Th/Pb monazite dating constrains granite melting to ~25–18.5 Ma in Manaslu and ~24–13 Ma in Everest-Makalu. The Manaslu sheeted sill complex was emplaced by progressive underplating with the oldest intrusions structurally above younger intrusions. Heat was dominantly derived by internal radioactive heating from crustal thickening with little or no contribution from shear heating along the MCT or from the mantle.
Himalayan Leucogranites: An Experimental Petrology Perspective
Authors: Scaillet Bruno , Pichavant Michel
Published: December 2024

The High Himalayan leucogranites (HHL) are produced by muscovite breakdown of a metapelitic source, at temperatures below 800 °C, with initial melt water contents of ~5–7 wt.%. The tourmaline-rich HHL variety is colder, possibly a fractionation product of the hotter two-mica HHL. HHL lack restites such as iron-rich garnet, which, when present, is Mn-rich, signaling fractionation processes. The low redox state of HHL mirrors that of their graphite-bearing source, yet there is evidence of a significant increase in fO2 during crystallization of some HHL. Their relationships with regional deformation call for late emplacement of the main bodies, which must have cooled at 3–4 kb to allow muscovite crystallization, which in turn imposes stringent constraints on unroofing rates of the collisional chain.

Published: December 2024

Employee retention is a critical challenge in the banking sector, with high turnover rates leading to significant costs and operational disruptions. This study investigates the mediating role of employee engagement in the relationship between recruitment and selection practices and employee retention at the National Bank of Bahrain (NBB). A quantitative cross-sectional survey approach was employed, with data collected from a random sample of 257 NBB employees across various departments and hierarchical levels. The study utilized structural equation modeling via SmartPLS to analyze the data. Results indicate that recruitment and selection practices significantly influence employee engagement (β = 0.861, p < 0.000) and employee retention (β = 0.455, p < 0.006). Moreover, employee engagement was found to have a significant positive effect on employee retention (β = 0.406, p < 0.018). Notably, the study reveals a significant indirect effect of recruitment and selection on employee retention through employee engagement (β = 0.35, p < 0.019), confirming the mediating role of employee engagement. These findings emphasize the importance of strategic recruitment and selection practices in fostering employee engagement and enhancing retention rates. The study significantly contributes to the literature on human resource management in the banking sector, providing a deeper understanding of employee engagement’s role in retention and offering practical implications for organizations seeking to improve their talent management strategies and reduce turnover.

Published: December 2024

he problem of controlling the interorbital maneuvers of a point in a gravitational field is considered. Using the first integrals of the system, a fairly simple synergetic regulator was designed. With its help, the problem of choosing the optimal point of departure from the initial orbit is investigated. At the same time, the maximum value of the thrust generated by the control is selected as a criterion. The problem of transition from the initial to the final orbit in the case of orbits touching is considered. The question of choosing a parameter defining the control vector is investigated.

The paper presents a generalized algorithm for designing closed optimal systems with a dynamic controller and a nonlinear actuator. The purpose of the proposed algorithm is to identify the area of system performance degradation, manifested as unintentional oscillations, due to the influence of actuator nonlinearity and reduce this area. The algorithm is implemented using a heuristic search algorithm and the method of sequential nonlinear correction. The results of the algorithm operation are shown on the PI control system of the angular plant motion with a saturated actuator. Simulation of the system with various input parameters showed the possibility of fluctuations in the system output. The numerical analysis results of the nonlinear system are presented in the form of exponential diagrams of the performance error, covering all input parameters.
On "classical" and "quantum" Limits at the Integration of a System of Autonomous Differential Equations
Authors:   Rocket Space Corporation “Energia” named after S.P.Korolev, Khatuntseva Olga Nikolaevna ,   Federal State Autonomous Educational Institution of Higher Education "Moscow Institute of Physics and Technology (State University)
Published: December 2024

The studies carried out in the author's earlier works show the possibility of a stochastic process in the numerical integration of systems of autonomous differential equations (ADE) of the Lorentz type. They also noted that with an increase in the number of equations (degrees of freedom) in the ADE system, the stochastic nature of the process decreases – the "determinization" of the process occurs. In this paper, an attempt is made to characterize the process of transition from one iterative step to another (when integrating the ADE system by numerical methods) by some average value of the time interval for all the equations of the system, and then to determine the relationship between this value and the change in the entropy of the system. Two limiting cases are found when describing such a system: "classical" - when time monotonically increases during the transition from one iterative step to another, and "quantum" - when time is defined ambiguously and a violation of cause-and-effect relationships in the system is possible.

The publication presents an approach to the use of discrete optimization algorithms, in particular, the search for suboptimal solutions. The theory of enumerators, proposed by the famous Leningrad mathematician I.V. Romanovsky, and the operation of their summation, which is proposed to be used to create multi-domain suboptimal algorithms, are considered. The paper presents an efficient algorithm to sum enumerators based on the recalculation of the Pareto boundary. Motivations for using the proposed algorithm within the framework of a well-known task in the field of Master Data Management are given.
On the Solvability of a Periodic Problem for a Two-dimensional System of Ordinary Differential Equations of the Second Order
Authors:   Vologda State University, Mukhamadiev Ergashboy , Naimov Alizhon Nabidjanovich ,   Vologda State University
Published: December 2024

In this paper we study the periodic problem with a period equal to 1 for a two-dimensional system of second-order ordinary differential equations, in which the main nonlinear part is generated by a polynomial in one complex variable. It is proven that if the convex hull of the roots of the generating polynomial does not contain numbers that are multiples of 2 i*pi, then there is an a priori estimate for solutions to the periodic problem. Under the conditions of an a priori estimate, using methods for calculating the mapping degree of vector fields, the solvability of the periodic problem for any perturbation from a given class is proven. The system of equations under consideration does not reduce to a similar system of first-order equations with the main positive homogeneous nonlinear part. For systems of first-order equations, the periodic problem was studied in the works of V.A. Pliss, M.A. Krasnoselskii and their followers using methods of a priori estimation and calculation of the mapping degree of vector fields. It is known that an a priori estimate of solutions to boundary value problems for systems of nonlinear ordinary second order differential equations is fraught with difficulties associated with an estimate of the first-order derivative of the solution when the solution itself is bounded. In this paper, using the example of a periodic problem for the considered system of second-order equations, it is established that the a priori estimate is deducible if we combine methods for studying similar systems of first-order equations and methods for qualitative research of singularly perturbed systems of equations. The results obtained can be further generalized for multidimensional systems of second-order equations, applying the idea of the directing function method.

Published: December 2024

Drought, earthquake, flood, and fire are disasters whose effects occur after a more extended period than other disasters. Meteorological drought is called the beginning of drought types. In this study, trend analyses and temporal changes in temperature, precipitation, and drought index values were carried out between 1981 and 2022 at three meteorological observation stations in the Southeastern Anatolia region of Türkiye. Standardized Precipitation Index, Standardized Precipitation Evapotranspiration Index, China-Z Index, and Effective Drought Index methods were used for drought analysis, while Sen's slope, Mann–Kendall, and innovative trend analysis methods were used to detect the trend in precipitation. It was determined that precipitation generally had tended to decrease, and drought increased since 1996. Although every type of dry and wet periods has occurred, normal dry periods were observed more. In the spatial distribution of drought, the inverse distance weighted method gives larger areas with more extreme drought and wet values than the Kriging method. The increase in extreme values in the region indicates that the severity of drought will increase. It has been determined that the region's water resources and agricultural activities are under pressure due to climate change and drought.

MIGRAÇÃO E RELIGIÃO
Authors: LOPES JR. Orivaldo P.
Published: December 2024

Desde os anos 1980, o Brasil se tornou um país emissor no processo migratório internacional, e os Estados Unidos foram um de seus focos principais. Desde então, as Igrejas Evangélicas, especialmente as Pentecostais, tornaram-se uma parte significativa da população brasileira. Ambos os processos estão interligados, pois, na medida em que o Brasil se afastava de uma estrutura social tradicional, sua população ia se sentindo cada vez mais livre para experimentar novas religiosidades e viver em outros países. A imigração brasileira para os Estados Unidos se concentrou em algumas cidades e regiões como Boston, New York, Florida e Newark (New Jersey). Nesse último caso, a presença portuguesa desempenhou um papel fundamental, devido à questão linguística. No verão de 2000, fizemos um levantamento meticuloso junto às 20 igrejas evangélicas de brasileiros e uma Assembleia de Deus de Portugueses em Newark. Em julho de 2013, as igrejas alistadas na pesquisa de 2013, em Newark, foram revisitadas e novas descobertas foram agregadas. Das 21 igrejas de fala portuguesa em 2000, o número cresceu para 130. Exceto algumas delas, a maioria das congregações está perdendo a segunda geração de imigrantes brasileiros. Os pastores e as comunidades religiosas tem tido um papel importante na construção de um ambiente acolhedor e salutar para os imigrantes. Igrejas são a principal fonte de ajuda antes que os imigrantes aprendam a recorrer ao apoio público e social. Entretanto, tendências a um fechamento social e político e o conflito entre os líderes eclesiásticos tem enfraquecido o impacto dessas mais de cem igrejas em Newark.

A constituição da identidade de gênero dos sujeitos é atravessada por vários saberes-poderes científicos e por preconceitos gerados pela cultura e pelos costumes de determinada sociedade. A sociedade heteronormativa acostumou-se com a divisão binária homem/mulher e, na maioria das vezes, concebe quem não se enquadra nesse padrão como algo anormal, como uma doença. Desta forma, possui uma visão limitada e não consegue compreender que existe uma diversidade dentro da sexualidade, tanto no que tange à orientação sexual, ao sexo biológico, às identidades de gênero e às performances de gênero. Os sujeitos são multifacetados, possuem personas diversas e vivenciam um personagem no cotidiano, muitas vezes para agradarem aos demais e tentarem ser aceitos, porém, não é uma tarefa tão fácil, pois o sistema de valores sociais, morais e jurídicos impulsionam os indivíduos considerados “diferentes” a se adaptarem aos critérios da “normalidade” por ele imposto, para não serem expurgados da sociedade. Para refletir sobre essa questão, este artigo se propôs a realizar um estudo de revisão e análise bibliográfica, buscando mostrar os fatores que estão envolvidos na sexualidade das pessoas e que contribuem para a constituição da identidade de cada ser. Como resultado, percebemos que os sujeitos são diversos e todosos fatores levados em consideração ₋ como a identidade de gênero, a orientação sexual, o sexo biológico e a performance de gênero ₋ se modificam entre um sujeito e outro, tornando cada indivíduo único em um universo de possibilidades.

SONHOS DE UNIVERSITÁRIOS NO CONTEXTO PANDÊMICO E O CENÁRIO POLÍTICO BRASILEIRO
Authors: Imbrizi Jaquelina Maria , De Souza Silva Jussara , Corrêa Ramos Gabriela , Fernandes Dimitry
Published: December 2024

A ação de extensão “Roda de Conversa sobre Sonhos” foi criada no ano de 2020 como forma de acolhimento das angústias e de partilha de experiências dos estudantes em decorrência da eclosão da pandemia de Sars-CoV-2 (covid-19). Trata-se de um espaço grupal que visa compartilhar sonhos, cujos encontros são realizados em ambiente virtual, via Google Meet, como uma forma de manter os vínculos entre estudantes e a comunidade universitária. O objetivo do artigo é apresentar três narrativas oníricas de universitários que participaram do primeiro ciclo do projeto, entre maio e julho de 2020. O método de análise do material produzido no grupo se utilizou de três dimensões de tratamento das narrativas oníricas: singular, social e comum e a prospectiva. Cabe destacar que o distanciamento social e as incertezas políticas colocaram desafios às instituições de ensino superior no sentido de convidá-las a inventar dispositivos de comunicação com os discentes e docentes, e de cuidado com o intuito de acolher a dimensão sociopolítica do sofrimento da comunidade acadêmica. Consiste em uma aposta na formação profissional que articula pesquisas científicas e experiências de acolhimento ao outro no processo ensino/aprendizagem em constante busca de diálogo com o contexto social e histórico.
COVID-19 E IDOSOS NO BRASIL

No Brasil, país com histórico e tradição colonial, o racismo estrutural é uma realidade que impacta a equidade em saúde e o bem-estar da população negra (parda e preta). Além disso, tem graves repercussões nas condições socioeconômicas, frutos de uma história escravocrata, patrimonialista e excludente que tem como resultado os piores indicadores sociais e de saúde da população afrodescendente. Esses pressupostos contrapõem-se a narrativas que propõem uma leitura sobre a covid-19 ser uma pandemia democrática, cujo argumento se alinha à retórica da democracia racial, conceito originado na metade do século XX, que defendia que o Brasil era dotado de boas relações raciais devido ao seu histórico de miscigenação e definições raciais imprecisas, o que corresponde a uma potente estratégia de manutenção do lugar de populações racializadas, como negros e indígenas, em uma produção da colonialidade moderna. Sob tais premissas, o objetivo deste artigo é discutir indicadores de saúde da covid-19, segundo o marcador social raça/cor da pele da população idosa brasileira, publicados pelo Ministério da Saúde do Brasil, haja vista a gravidade dessa doença nesse grupo etário, as controvérsias desse quesito nessas publicações e o racismo estrutural que remonta à escravidão.

SOFRIMENTO PSÍQUICO NO CONTEXTO DA CRISE SANITÁRIA DA COVID-19 NO BRASIL
Authors: Pereira de Carvalho Paulo Dourian , Cunha Dantas Maria da Guia , Felizardo Ana Paula , Botazzo Carlos
Published: December 2024

A crise sanitária da pandemia da covid -19 produz expressões de sofrimentos no Brasil e no mundo. Desde março de 2020 o país é desafiado pelo patógeno SARS-CoV-2, vírus mutante, potente, pouco conhecido e letal, que já levou a óbito mais de seiscentas mil pessoas, e infectou mais de 30 milhões de pessoas somente em solo brasileiro. Ademais, as consequências ultrapassam o campo da Saúde Coletiva e afetam as dinâmicas econômicas e sociais na contemporaneidade, seja pelas disputas de narrativas entre salvar a economia ou vidas, seja pela maior exposição dos sujeitos em desvantagem social e condições de vida ainda mais precárias. Consequências diretas que se tem percebido como efeito de dois anos de pandemia são o desenvolvimento e o agravamento de quadros do sofrimento psíquico, que se apresentam em parte considerável da população. Organismos internacionais, como a Organização Mundial da Saúde (OMS), além de psicólogos e psiquiatras têm considerado este fenômeno na condição de uma “epidemia paralela” ao se referirem ao quadro de adoecimento mental que tem se desenhado. Desse modo, trata-se de um assunto relevante pela sua influência na perda de qualidade de vida das pessoas e de suas famílias. Por tal razão, este ensaio tem como objetivo analisar como a emergência sanitária influiu na saúde psíquica da população, com uso de categorias teóricas desenvolvidas por expoentes do pensamento social contemporâneo, particularmente os conceitos de “Estado de exceção” de que nos fala Giorgio Agamben, a “necropolítica” explicitada por Achille Mbembe, as noções de “biopolítica” e “controle de corpos” de Michel Foucault, além das discussões sobre “vidas precárias” de Judith Butler, entre outras categorias e autores. Além disso, também realizamos breve reflexão sobre a gestão das informações que circulam nas redes sociais durante a pandemia e seus impactos na saúde mental dos brasileiros(as). Os referidos autores e suas teorias, embora distintas, confluem, nesta análise, no sentido de oferecer lastro para o aprofundamento do tema do sofrimento psíquico no contexto pandêmico no Brasil. Entendemos que esta é uma discussão urgente e que precisa ser trazida à baila a fim de que, a partir do debate científico e político, possamos encontrar alternativas que nos ajudem a diminuir os efeitos nocivos da epidemia na produção de subjetividades na sociedade brasileira.
A REPRESENTAÇÃO DA MULHER VELHA EM CONTOS DE CLARICE LISPECTOR
Authors: A. Pereira Maria do Rosário
Published: December 2024

O objetivo deste trabalho é apresentar como se dá a representação das mulheres velhas em alguns contos de Clarice Lispector, a saber: “Ruído de passos”, “Feliz aniversário” e “Mas vai chover”. Aspecto pouco explorado na literatura brasileira, o envelhecimento é um tabu social, principalmente no que se refere ao envelhecimento feminino, uma vez que as mulheres, no sistema capitalista, são vistas como corpos erotizados e potenciais consumidoras de produtos de beleza e afins. Já nos anos 1950, Clarice Lispector debruçou-se sobre o tema, em contos e crônicas, e o olhar da escritora aponta para o lugar-comum da solidão em meio às relações sociais e também nos relacionamentos interpessoais, já que a mulher velha ocupa um lugar de menos valia social, inclusive no que diz respeito ao modo como sua sexualidade é vista. Tendo parte de sua literatura calcada numa crítica às relações familiares patriarcais, como na coletânea Os laços de família, Lispector evidencia como o envelhecimento feminino é um topos a reiterar a falência desse modelo. Desse modo, os contos da escritora demonstram o fato de a velhice ser uma construção social e cultural, e não apenas um fator biológico, como bem destacou Simone de Beauvoir em seu clássico A velhice.
