Authors: Dela-Silva Silmara , Carneiro Ceres Ferreira
Published: February 2024

Resumo Este artigo empreende um gesto de leitura do modo como a mídia e os discursos que nela são formulados e circulam comparecem nas reflexões teórico-analíticas propostas por Michel Pêcheux, na teorização da análise de discurso. Especificamente, volta-se a dois pontos: a) o modo como os discursos da/na mídia são mobilizados em textos de Pêcheux e outros pesquisadores a ele relacionados, em suas produções no cenário francês, entre o final da década de 1960 e início dos anos de 1980; b) o modo como essas reflexões que perpassam a obra pecheutiana encontram ressonância a partir da reterritorialização da análise de discurso no Brasil, resultando em análises de corpora diversos e teorizações acerca dos discursos jornalístico, publicitário e digital.
INTERAÇÃO FICTIVA EM DISCURSO DIRETO: COMO E POR QUE LÍDERES RELIGIOSOS CONVENCEM MULTIDÕES
Authors: Silva Jaime Ulisses da , Rocha Luiz Fernando Matos
Published: February 2024

Resumo Este artigo investiga por que os adeptos de certas religiões são, por vezes, tomados por uma sensação mística de que padres, pastores e líderes espíritas estão pregando direta e particularmente para seus “corações e mentes” durante missas, cultos e palestras. Sustenta-se que o uso da Interação Fictiva (IF), especificamente em Discurso Direto Fictivo (DDFic), tem papel crucial na tentativa de provocar essa sensação. Entende-se a IF como o fenômeno do uso do Frame de Conversa para estruturar pensamento, gramática e discurso (Pascual, 2014). De metodologia qualitativo-interpretativa e agregando aspectos cognitivos e interacionais, o trabalho resulta no achado de que a Interação Fictiva, como estratégia argumentativa, viabiliza deiticamente acesso a um espaço conceptual genérico, pronto para ser preenchido e instanciado pela audiência. Demonstra-se, ainda, como o DDFic oportuniza projeções dos fiéis em si mesmos e a consequente sensação de que o orador adivinha o que eles pensam/sentem.

Opportunities for and challenges to a translingual approach to ELT in Brazil
Authors: Tagata William Mineo , Pricinoti Brenda Mourão , Ferreira Guilherme Rodrigues
Published: February 2024

Abstract: In this article we reflect upon the opportunities for and challenges to the implementation of a translingual approach in three different ELT contexts in Brazil, based on three autoethnographic accounts. The first account was written by an English teacher in early childhood bilingual education; the second, by an undergraduate English language and literature student and English teacher working in a private language school; the third, by a university professor in an English language and literature undergraduate course. In spite of their differences in terms of target audience, available resources for meaning production and ecological features in general, there seems to be a monolingual orientation pervading the three contexts. Despite the many challenges posed by this monolingual bias, which reflects the coloniality of power (MIGNOLO, 2000) and linguistic imperialism (PHILLIPSON, 1993, , 2009), the three authors believe in the importance of creating translingual spaces (GARCÍA; WEI, 2014) where students can negotiate their linguistic and cultural differences. This belief is grounded in the fact that in each context opportunities for translingual practices could be found and created.
Emerging translingual praxiologies in three English teacher professional development contexts in the Brazilian Midwest
Authors: Blum Avram Stanley , Santclair Dllubia , Silva Kleber
Published: February 2024

ABSTRACT: In this article, we explore our attempts to infuse the classes we teach with our emergent translingual praxiologies. We describe this process in three educational contexts: an undergraduate English major course, a graduate course in Linguistics, and an in-service course for public school English teachers, all in the Midwest region of Brazil. To do so, we use qualitative, interpretive research through personal narratives. For us, translingual understandings emphasize language as fluid, negotiable, and creative, in contrast to monolingual orientations that hold languages to be discrete, fixed, and finite. Such ideas hold potential for developing (de)colonial approaches to linguistic education, which value diverse ways of knowing and being that potentially enhance life across the globe.
Negras guerreiras: o lugar da memória na performance insurgente de uma artista de periferia
Authors: Oliveira Bruno Coutinho de Souza
Published: February 2024

RESUMO: Partindo de uma postura transdisciplinar e transperiférica sobre a produção e circulação de conhecimento, esse texto busca, a partir da obra musical de uma artista negra, independente e periférica, refletir sobre o papel da memória como instrumento tático de resistência e ressignificação do povo negro – mais especificamente da mulher negra – na sociedade brasileira. Tendo como perspectivas teóricas e analíticas autoras como Leda Martins (2003) e Lélia Gonzalez (1984), procuro mostrar como a música, por meio da interpretação, da letra e do gênero sonoro, possibilita a mobilização dessa memória por meio de performances periféricas insurgentes diante de lógicas de opressão marcadas pelo racismo e o sexismo. Essas performances constroem-se dentro de um cronotopo periférico em contraposição a cronopolítica racista. Por fim, o texto reflete sobre como o resultado dessa dinâmica possibilita a construção de saberes dentro de uma agenda socialmente engajada de pesquisa e de produção de conhecimento.

Published: February 2024

ABSTRACT Objective: The aim of this study was to evaluate the extent to which orthodontic treatment need is perceived by the patients and by the orthodontist, as well as the possible impacts on the OHRQoL (Oral Health-Related Quality of Life) over the course of conventional orthodontic treatment in adolescent patients. Methods: The sample consisted of 55 adolescents. The perception of patients and orthodontists relative to the malocclusion was evaluated by the IOTN (Index of Orthodontic Treatment Need). The OHRQoL was evaluated by the Child-OIDP (Child-Oral Impacts on Daily Performances) questionnaire before the conventional orthodontic appliance was bonded (T0); and at the following time intervals: after one week (T1), one month (T2), three months (T3), six months (T4), and after the end of orthodontic treatment (T5). Results: Adolescents who had large orthodontic treatment needs had a poor OHRQoL, according to their self-perception (p=0.003) and according to the orthodontist’s perception (p<0.001), when compared with patients with small and moderate needs. There was statistically significant difference in the OHRQoL between the time intervals T0 and T1 (p=0.021), T2 and T3 (p<0.001), T3 and T4 (p=0.033), and T0 and T5 (p<0.002). At the end of treatment, all evaluated participants reported an improvement in OHRQoL. Conclusions: It was concluded that adolescents and orthodontists agreed with regard to the perception of orthodontic treatment need. In the first week and in the first month of orthodontic treatment, there was a negative impact on the OHRQoL. After three months, an improvement of OHRQoL was detected, which has progressed over time.
Qualidade da educação e desempenho de escolas públicas de Minas Gerais nas Olimpíadas de Matemática
Authors: Almeida Andréa Cristina de , Brunozi Júnior Antônio Carlos , Tupy Igor Santos
Published: February 2024

Resumo No presente estudo analisou-se a relação entre a qualidade da educação – estrutura escolar física, estrutura escolar pedagógica, docentes, discentes e políticas educacionais - de escolas públicas de municípios mineiros e os seus desempenhos, de premiados, na OBMEP. Tal investigação tem como diferencial a utilização de uma abordagem quantitativa, demonstrando que a OBMEP é relacional, baseada na qualidade social da educação e na ótica não equânime do sucesso das escolas públicas em políticas relacionadas à educação. Na literatura existente, a OBMEP foi discutida preponderantemente pelas abordagens pedagógicas ou de conteúdos das provas, e não como ação a ser influenciada nas escolas. Com uma amostra de 420 escolas públicas pertencentes à regional MG06 da OBMEP, aplicou-se um modelo de regressão de Poisson, associando-se variáveis representativas da qualidade social da educação - fatores intra e extra escolares - com o desempenho na OBMEP, quantidade de medalhas obtidas pelas escolas. Percebeu-se que para apresentar um desempenho satisfatório, ou seja, obter sucesso na OBMEP, alcançando-se premiações, é necessário que as escolas públicas tenham infraestrutura adequada, em condições para o exercício do trabalho docente, estudantes em situações favoráveis de acesso e permanência no ensino regular, além da atuação permanente do Estado mediante o desenvolvimento de políticas públicas educacionais. Tais resultados sinalizam a necessidade de maior comprometimento das esferas políticas e sociais para a melhoria da qualidade da educação pública básica no Brasil, para que ocorra maior divulgação do potencial da OBMEP como política pública de inclusão social e não só para a busca de resultados e premiações.
Assessing the taxonomic sufficiency of macroinvertebrate communities and their potential to distinguish the impacts of land use on lowland streams in Uruguay
Authors: Suárez Bárbara , Barrios Margenny , Mello Franco Teixeira de
Published: February 2024

Abstract: Aim Macroinvertebrates are extensively employed as bioindicators for evaluating how stream ecosystems respond to alterations in physical and chemical habitats caused by human activity. Although family-taxonomic level is usually used to identify macroinvertebrates in biomonitoring programs, coarser taxonomic resolution may provide similar information. We aim to evaluate taxonomic sufficiency by comparing macroinvertebrate communities at the order and family levels to differentiate the effects of different land uses. Methods We conducted colonization experiments using artificial substrates in streams representing three land use types: urban (U, n=3), intensive agriculture - dairy production (AD, n=4), and extensive cattle ranching (CR, n=4). Results We obtained similar results using both taxonomic levels, which effectively distinguished the impacts of different land uses. In the sites examined, the majority of indicator groups exhibited only one family per order, with the exception of Ephemeroptera (Leptophlebiidae, Baetidae, and Caenidae). Notably, Baetidae and Caenidae were more prevalent in streams associated with extensive cattle ranching (CR). Conclusions Although this study provides a clear precedent, further investigation of these systems and other land uses (e.g., afforestation) is needed to validate this pattern. Coarser taxonomic assessment holds potential as a cost-effective method for stream monitoring and assessment in Uruguay.

Published: February 2024

Natural killer (NK) cells are innate lymphoid cells that exhibit high levels of cytotoxicity against NK-specific targets. NK cells also produce various cytokines, and interact with T cells, B cells, and dendritic cells to effectively serve as frontliners of the innate immune system. Produce various cytokines, and interact with T cells, B cells, and dendritic cells to effectively serve as frontliners of the innate immune system. Moreover, NK cells constitute the second most common immune cell in the liver. These properties have drawn significant attention towards leveraging NK cells in treating liver cancer, especially hepatocellular carcinoma (HCC), which accounts for 75% of all primary liver cancer and is the fourth leading cause of cancer-related death worldwide. Notable anti-cancer functions of NK cells against HCC include activating antibody-dependent cell cytotoxicity (ADCC), facilitating Gasdermin E-mediated pyroptosis of HCC cells, and initiating an antitumor response via the cGAS-STING signaling pathway. In this review, we describe how these mechanisms work in the context of HCC. We will then discuss the existing preclinical and clinical studies that leverage NK cell activity to create single and combined immunotherapies.
Advancing landslide early warning systems through saturation monitoring and prediction
Authors: Sudani Prashant , Patil Kailas
Published: February 2024

Landslides most commonly occur in the rainy season, resulting in damage to infrastructure and human lives. An early prediction framework for landslides would clearly help to mitigate damage. In this work, a prediction framework for shallow landslide initiation was developed and validated with a real case study. To assess the reliability of the prediction framework, back-analysis of a landslide that occurred in Malin village, Maharashtra, India on July 2014 was performed. Relations of landslide stability with soil saturation were established through a physically based approach using GeoStudio software. A leaky barrel algorithm was developed for the study location to monitor the effect of rainfall' on soil saturation. Simulation results of landslide stability were compared with the rainfall–soil saturation algorithm based on the leaky barrel. The presented framework was found to have good predictability of shallow landslide occurrence and is therefore recommended for real-time monitoring of landslide-prone locations.
Patriotic and religious activity of the Gymnastic Society “Sokol” in the Polish lands (until 1939) – an outline
Authors: Urban Renata
Published: February 2024

The Gymnastic Society “Sokol” (“Falcon”) (hereinafter: GS “Sokol”) was the first and for several years the only Polish organisation to obtain a permission from the authorities of the partitioning states to carry out its activities during the period of partitions. The first falcon nest was established in Lviv in 1867, with further nests being set up in the cities of the Austrian, Prussian and later Russian partitions. Although – as the name suggested – the GS “Sokoł” was a gymnastic association, other forms of activity also played a significant role in its programme of activity. Singing, reading and caring circles were formed in the nests and members of the GS “Sokoł” participated in religious and patriotic ceremonies, thus cultivating Polish national traditions. Evenings and rallies were organised, commemorating religious holidays and important events in the history of the Polish nation, which reminded us of common goals and ideals during the period of national captivity. “Sokol” took on the duty of teaching native speech and native history. The scope and nature of the patriotic and religious activity of the GS “Sokol” was best evidenced by the National Commandments and the National Sins which were contrasted with them. Their very name and number indicated deep religiousness of the falcons. It derived not only from the authentic faith of the members of the GS “Sokol” but from the ideology of the movement. In the tragic historical moments of national captivity they placed their hope in God and found solace in prayer. All Sokol celebrations as well as everyday activities of the GS “Sokol” were of a patriotic-religious nature.
Variability and reliability in the AXB assessment of phonetic imitation
Authors: MacLeod Bethany
Published: February 2024

Speakers adjust their pronunciation to come to sound more similar to recently heard speech in a phenomenon called phonetic imitation. The extent to which speakers imitate is commonly measured using the AXB perception task, which relies on the judgements of listeners. Despite its popularity, very few studies using the AXB assessment have considered variation or reliability in the listeners’ performance. The current study applies a test-retest methodology focusing on the performance of listeners in the AXB assessment of imitation, which has not been considered explicitly before. Forty listeners completed the same AXB experiment twice, two to three weeks apart. The findings showed that both sessions reach the same overall conclusion: the listeners perceived the same overall amount of imitation in both sessions, which is taken to mean that the shadowers did imitate and that the AXB task is reliable at the group level. Furthermore, the findings show that listeners vary substantially in their performance in the AXB assessment of imitation, but that they are relatively consistent in this performance across sessions. This suggests that differences in AXB performance at least partly reflect differences in ability to perceive imitation, rather than simply random variation. 
Progress, Positivism, and Scientific Revolution: The Synthesis of Darwin's Theory of Evolution
Authors: Liu Yiming
Published: February 2024

Bridging the rift between the sciences and the humanities is important for fostering creativity in all fields of study. Many scientific theories, especially those producing the most profound impact on our understanding of the world, are a continuity of sociological phenomena and of history. This project uses Charles Darwin’s theory of evolution as an illustration of the intrinsic ties between science and humanities. Darwin's theory, which has its basis in scientific observation, would ignite intense philosophical and theological debate, upending creationist beliefs and paving the way for an anti-teleological view of nature. When Darwin was formulating his theory of evolution, the industrial revolution provided a visceral model for the archetypal survival of the fittest. Philosophical positivism and English analytical philosophy exalted rational, scientific observation as the pinnacle of "truth" while romantic poets sought answers to philosophical and aesthetic discourses in the natural world.My Latham Science Engagement Initiative project sought to engage humanities majors with concepts in evolutionary biology through distribution of a brochure, entitled “Progress, Positivism, and Scientific Revolution: The Synthesis of Darwin’s Theory of Evolution,” during general education and humanities classes on campus. My intention was to showcase Darwin’s theory of evolution as a synthesis of its historical context, scientific predecessors, and aesthetic milieu. I also informed the classes about a flagship science event — Iowa City Darwin Day — in hopes of increasing non-science major attendees.

Objectives: In India, the professional performance of the academic faculty is assessed annually using Academic Performance Indicator (API) as per the University Grants Commission (UGC), Government of India. This is a manual model is cumbersome in filling, and time-consuming. As a planned change and a measure to introduce technology-based platforms in JSS Academy of Higher Education & Research (JSSAHER), Mysuru, India, we have designed, developed, and validated digital platform technology to evaluate the annual performance of faculty working in medical, dental, pharmacy, life sciences fraternities. Methods: Academic Performance Indicator (API) guideline as per the University Grants Commission (UGC), Government of India, was used to design and develop the digital performance-based appraisal system (d-PBAS), and its performance was validated (20% random sampling) by comparing the manual and digital data entered by the faculty from different disciplines of JSSAHER. Findings: The present manuscript demonstrates the designing and validation methodology of d-PBAS. Software Development Life Cycle (SDLC) process and Waterfall model was adopted to develop d-PBAS. The digital platform was assessed for the performance and ranking of the faculty. More than 96% of the users expressed satisfaction and 4% expressed dissatisfaction in d-PBAS. Novelty: For the first of its kind in a university set up in India, JSSAHER designed and validated the digital performance-based appraisal system to evaluate academic performance. Since d-PBAS was developed using the SDLC process and Waterfall model it is easy and consumes less time to enter the data. The most important highlight is d-PBAS helps to rank the faculty performance automatically. The design and validation of d-PBAS described in the present manuscript are simple, robust, cost-effective, and have a go-green value.

Stream Applications: A Consistent Active Management Approach for Multi-Core Cache
Authors: R.Kennady Et al.
Published: February 2024

This paper proposes a novel method for managing cache consistency in multi-core systems when executing stream applications. The method involves arranging a mark cache for private data caches, which includes an optional integrality descriptor for shared reading and writing data states and shared data manipulation positions. The integrality descriptor identifies the current mode of operation for shared data in the private data cache. Additionally, the method utilizes a two-dimensional array register, referred to as the shared data manipulation position, with width N and depth M, where N distinguishes between different cache blocks and locking territories, while M corresponds to the number of cache blocks. This enables the identification of the cache capable or block corresponding to shared data during read and write operations. The proposed method offers simplicity, ease of operation, low hardware implementation cost, good extensibility, and strong configurability, ultimately improving system effectiveness.
Multi-core Tile-based Processor with Transactional Memory for Efficient Use of Resources
Authors: R.Kennady Et al.
Published: February 2024

This research focuses on the design and implementation of a multi-core processor with a tile structure and transactional memory method to improve resource utilization and address the limitations of hardware transactional memory systems. The proposed processor utilizes a network-on-chip to connect the tiles, and the number of each tile type can be adjusted based on application requirements. In this architecture, L2 cache is bypassed during transaction execution, and a router on the chip efficiently routes and stores transaction read-write requests in a transaction buffer area. A partition strategy is employed to allocate a portion of the available region specifically for transaction threads, and the read-write operations of transactions are recorded in the transaction buffer area. Furthermore, the size of the partition dynamically expands as the transaction read-write set increases. Through these innovations, the research aims to address issues related to resource waste, low buffer area utilization, and lack of support for thread switching and migration. The effectiveness of the proposed design is evaluated through simulations and benchmarking, demonstrating its ability to mitigate transaction buffer overflow and enhance overall performance.

Cloud Storage Systems with Secure Attribute-Based Access Control
Authors: O.Pandithurai Et al.
Published: February 2024

This research presents a novel approach to safe access procedure in cloud storage structure by addressing the challenges associated with managing and distributing complex secret keys. The proposed procedure utilizes attribute-based access control and incorporates a client process, an authentication terminal process, and a storage terminal process. The client generates a main secret key and public parameters for each user using an attribute password mechanism. The authentication terminal maintains user attribute, file attribute, and attribute secret key databases. Access control is determined by constructing an access control string from the attributes of the user, file, and file operation type, enabling fine-grained access control and accommodating large-scale user dynamic expansion. Consequently, the access control costs of the cloud storage structure are significantly reduced, while offering a flexible, effective, and secure access control mechanism for safe storage structure access.

Technique for Cache Management in Solid
Authors: O.Pandithurai Et al.
Published: February 2024

This research presents a novel cache management method for solid-state discs (SSDs) that aims to efficiently utilize the limited cache space and improve the cache hit rate. The method involves the establishment of various data structures, including a page cache, a replace block module, a new page linked list, a physical block chain list, and a physical page state list. When an input/output (IO) request from a host is received, it is processed through the page cache. In cases where a writing request is executed and the page cache is full, a block replace process is triggered within the SSD to free up space. To minimize erasure and page copy operations, the method selects a candidate replace block with the highest failure ratio from the rear half of the physical block chain list as a replacement. This ensures that a block written in the flash medium contains a maximum number of dirty data pages and a minimum number of effective data pages. The proposed cache management method is designed to enhance the overall performance of SSDs by reducing sequential rubbish recovery caused by the presence of dirty data pages, and it is also user-friendly and easy to operate.

Published: February 2024

This research presents a novel method for analyzing energy flows in integrated energy systems (IES) using a likelihood-based approach. The proposed method incorporates the concept of Probabilistic Load Flow (PLF) from power systems into the analysis of IES likelihood energy flow points. By assessing the qualitative impact of uncertainties on the probability distribution of the state quantities in integrated energy systems encompassing electricity, air, and heat, this method enables a comprehensive evaluation of the load and output of wind electric fields. The outcomes of this research contribute to establishing a solid foundation for real-time network planning, steady-state analysis, optimized operation, control, and safety analysis of integrated energy systems.
Evaluating the Application of Artificial Intelligence in Electrochemical Manufacturing: A Comprehensive Analysis
Authors: Hari Prasadh S Et al.
Published: February 2024

Electrochemical machining (ECM) is a critical manufacturing process used to produce complex and difficult-to-machine materials with high precision and accuracy. The process involves the removal of material through a controlled electrochemical reaction between an electrolyte and an electrically conductive workpiece. With the increasing demand for high-quality products and the need to improve manufacturing efficiency, the use of artificial intelligence (AI) in ECM is becoming increasingly important. AI algorithms can be used to optimize process parameters, detect defects and anomalies, predict maintenance requirements, and optimize the design of workpieces and tooling. This paper provides an overview of the role of AI in ECM, including recent developments, applications, and future prospects.

The dynamics of a broad-area vertical-cavity semiconductor surface-emitting laser (VCSEL) is theoretically investigated with due regard for the Henry factor. A linear analysis of the stability of a spatially homogeneous lasing regime is performed and the modulation instability is shown to develop in such lasers. The minimum size of the aperture at which the instability of the optical field begins to develop is determined. The results are confirmed by the numerical solution of a system of differential equations. It is shown that the suppression of the modulation instability can be achieved by injecting into the resonator an external low-amplitude optical radiation.

This work is devoted to measuring the depth of the 3D object using the structured light method, in particular, phase shift profilometry. Theoretical studies on the methods of three-dimensional measurement systems and fringe projection profilometry are presented. The phase shift profilometry method with an improved calculation of the frequency of sinusoidal patterns is applied. In practical implementation in the environment (20 cm × 30 cm), the algorithm is tested on a stepped object consisting of eight steps with a difference of 150 mm between two successive steps. In this case, the achievable error for measuring such an object is 20 mm. Our method has great potential in industrial applications where the measurement of the smoothing of the surface of the object is needed to find the defect in the surface with high accuracy without contacting the object.

We investigate the optical implementation of a second-order differentiation operation using a metal-dielectric layered structure in the oblique incidence geometry. It is shown that the transformation of the profile of a three-dimensional light beam occurring upon its reflection from a layered structure can be described using the theory of linear systems. The transfer function of the corresponding linear system is obtained, and it is shown that if a layered structure has a reflection zero of the second order with respect to the spatial frequency for one of the polarizations, the transformation performed by the structure corresponds to the weighted sum of the second derivatives of the incident beam profile with respect to the spatial coordinates. Using the presented theoretical description, layered metal-dielectric structures for computing the second derivative with respect to one of the spatial coordinates and for computing the Laplace operator of the profile of a three-dimensional linearly polarized light beam are calculated. The presented numerical simulation results demonstrate high-quality computation of these operators.

This study proposes analytical estimate for the size of a binary raster figure region which is guaranteed to contain the rotational symmetry focus. Focus here is the point a maximum Jaccard index between initial figure and rotated one. The size of the region is determined by the lower estimate of the intersection area during the rotation of the approximating primitives, considering the sizes of the inner and outer parts of the figure relative to the primitive. The smallest circumscribed circle or ellipse and sets of concentric circles and ellipses produced by the principal component analysis were used as the approximating figure. To verify the hypothesis that the size of the region is insignificant compared to the area of the figure, we numerically simulated the proposed method with test image datasets.
Phase Equilibria and Critical Phenomena for Cut 3 of the Qua­ ternary System Water - Pyridine - Butyric Acid - Potassium Chloride

Published: February 2024

Phase equilibria and critical phenomena in cut 3 of the quaternary system water - pyridine - butyric acid - potassium chloride whose constituent ternary liquid system had a closed binodal curve were studied by means of the visual-polythermal method within 5-90°C. We have determined the temperature dependence of the solution composition corresponding to the critical solution point of the immis- cibility region. Phase state isotherms constructed on the triangle of the cut for twelve temperatures have allowed topological transforma­ tion of the phase diagram for the examined cut of the composition tetrahedron of the system with temperature changes to be revealed.
