In the search for alternative means for teaching mathematics, modeling persists as one of the most effective actions, with the purpose of modeling real-life situations, obtaining equations that allow simulating certain phenomena. Attributing this ideology to this ideology, this work presents the use of trigonometric functions, more specifically the Fourier transform, through an experiment, to obtain characteristic signals of vibration amplitude in dynamic systems. This is a low-cost experiment, applicable in high school/technical education, through a pedagogical practice. In the search for works focused on teaching periodic functions of the type sense and cosine, a systematic review was carried out, identifying the absence of publications of works that are directly related to periodic functions with the Fourier transform in high school/technical education. However, in the systematic review, a large number of publications of works using the Fourier series and transform in various applications in the branches of science and engineering in solving characteristic problems of signals. The method employed in this work was based on an experiment that uses equipment to generate characteristic vibration signals. Initially, a spreadsheet was used to work with known periodic functions, gradually evolving to the experiment with more specific applications in vibration signals. The study contributes to the pedagogical practice that allows the student to learn periodic functions of the sine and cosine type, initially applying the basic concepts of the functions, which can be compared to real situations with the use of the spreadsheet. The proposed pedagogical practice aims to contribute to the teaching of sine and cosine functions with the application of the practical experiment, allowing the student to identify the use of mathematics in specific or real applications.

This research analyzes the budget management of the Federal University of São Carlos (UFSCar), focusing on budget centralization within a multicampus structure in a context of fiscal constraints and instability in financial execution during the period from 2021 to 2025. The study is based on the problem of understanding to what extent the university’s budget insufficiency results from inequalities in the distribution of resources among Federal Higher Education Institutions (IFES) and how centralized budget management has responded to this scenario, considering its strategies, levels of effectiveness, and main obstacles. The research adopts a qualitative, exploratory, and descriptive approach, grounded in participant observation, combined with documentary analysis and the use of institutional data from UFSCar and national databases, such as data systematized by Associação Nacional dos Dirigentes das Instituições Federais de Ensino Superior (ANDIFES) [National Association of Directors of Federal Higher Education Institutions]. The analysis was conducted based on analytical categories, especially occurrences, strategies, effectiveness, and obstacles, allowing for an integrated interpretation of budgetary dynamics during the analyzed period. The results show that budget centralization has consolidated itself as the predominant governance strategy, contributing to control, resource rationalization, and mitigation of fiscal risks. However, its effects on effectiveness appear ambiguous, since, while it ensures budgetary discipline, it also limits the autonomy of units, administrative flexibility, and the capacity to adapt to institutional demands, especially in the multicampus context. Furthermore, the research demonstrates that budget insufficiency does not result exclusively from internal management factors, but is also associated with structural constraints related to resource distribution within the federal higher education system. In this sense, the effectiveness of budget management is understood as a relational phenomenon resulting from the interaction between external funding constraints, institutional strategies, and internal organizational dynamics. As a contribution, the study offers an integrated analysis of budget management in multicampus universities, proposing elements to improve decision-making processes, informational controls, and resource allocation, aiming to promote greater effectiveness, transparency, and equity in public university administration.

Current production and consumption patterns overload ecological systems and push the Earth beyond the Holocene. In this context, integrating Planetary Boundaries (PB) into Life Cycle Assessment (LCA) termed Absolute Environmental Sustainability Assessment (AESA) transcends relative per-product evaluations by measuring impacts against absolute limits. The objective of this thesis was to adapt and apply AESA to dairy production systems in Brazil to analyze targets for absolutely sustainable production. A Systematic Literature Review (SLR) identified 42 empirical articles grouped into three clusters of AESA methods: LCIA-based method (51% of articles), PB-based method (21%), and ES-based method (16%). These methods were adapted and applied to free-stall, compost barn, and semi-confined systems. In the LCIA-based method, five impact categories (climate change, acidification, particulate matter formation, and freshwater and marine eutrophication) were analyzed via LCA using the Environmental Footprint method; in the PB-based method, elementary flows were multiplied by characterization factors (climate change, ocean acidification, and biogeochemical flows of phosphorus – P and nitrogen – N). Carrying capacity was allocated using Ability to Pay (ATP) and equal per capita (EPC) approaches combined with economic value (EV). In contrast, the ES-based method confronted demand (LCA impacts) with the supply of ecosystem services. The SLR indicated that the LCIA-based method stands out for its ease of application, the PB-based method requires greater analytical effort to report data in PB metrics, and the ES-based method offers greater scale flexibility and geographic resolution, although constrained by supply data. In the application using the LCIA-based method, all systems proved unsustainable for climate change regardless of allocation. Conversely, free-stall and compost barn systems were sustainable in the acidification and biogeochemical P flow categories, whereas the confined system only achieved sustainability in acidification under EPC+EV allocation. The worst performance occurred in the ES-based method, where most systems were unsustainable; only the semi-confined system achieved sustainability in N and P cycling categories. The findings pointed to impact reductions of up to 178-fold to operate within carrying capacity, a scenario that tends to generate economic viability challenges and encourages the adoption of more regenerative approaches. Thus, while improvement in LCIA and PB methods relies on reducing absolute impact, the ES-based method additionally demands an increase in carrying capacity.

Ecological restoration of the Cerrado biome faces challenges related to the high functional diversity of species, environmental degradation caused by land-use change, and invasion by exotic grasses. Despite the increasing number of restoration initiatives in savanna ecosystems, studies investigating the effects of fertilization on the growth of native non-arboreal species, particularly herbaceous and shrubby species, remain scarce. In this context, the present study aimed to evaluate the effects of fertilization and precipitation on the growth of native non-arboreal Cerrado species in a restoration area located in the state of São Paulo, Brazil. Five shrubby species—Aldama arenaria, Campomanesia adamantium, Cochlospermum regium, Psidium australe, and Solanum lycocarpum—and five herbaceous species—Ananas ananassoides, Andropogon leucostachyus, Aristida jubata, Imperata brasiliensis, and Loudetiopsis chrysothrix—were analyzed. Individuals were monitored monthly over an 18-month period in plots subjected to two treatments: no fertilization and NPK fertilization. The relative growth rate in volume (RGRᵥ) was analyzed using linear mixed-effects models with random intercepts for each individual, including final interval volume, fertilization treatment, and accumulated precipitation between growth intervals as fixed effects. The results showed that most species exhibited responses primarily associated with individual size, whereas the effects of fertilization were species-specific. Precipitation influenced growth differently among species, resulting in positive, negative, or non-significant responses. The functional forms that best described the relationship between relative growth and volume varied among linear, logarithmic, and quadratic models, highlighting distinct ecological growth strategies. Overall, the results indicate that the growth of non-arboreal Cerrado species is mainly driven by functional traits and environmental conditions, suggesting that ecological restoration strategies should account for the ecological and ontogenetic particularities of the species employed.

Philosophy teaching in public schools located in peripheral areas often involves dealing with a paradox: a discipline that carries the potential for critical thinking and emancipation, yet frequently becomes an instrument of symbolic reproduction. This dissertation investigates how Philosophy teaching can resist the logic of Paulo Freire’s “banking education” and Pierre Bourdieu’s concept of symbolic violence, proposing emancipatory practices grounded in the realities of peripheral schools in São Paulo state, Brazil. The research adopts a qualitative, critical-dialectical approach, articulating theory and practice through the participatory design and implementation of a card game entitled Resistência (“Resistance”), developed in collaboration with students from Escola Estadual Manoel Patrício do Nascimento, in Botucatu, São Paulo, Brazil. The game was conceived as a tool for philosophical experimentation, inspired by marginalized thinkers and concrete experiences from the territory, aiming to transform teaching into a critical, dialogical, and liberating experience. The results indicate that philosophical practice, when grounded in listening and co-authorship, enables student engagement and identity recognition while challenging the reproductive structures of the school system. Thus, Philosophy teaching, when experienced as a lived practice, becomes an act of resistance and hope within marginalized contexts, affirming the power of thought as an emancipatory gesture.

This thesis maps and analyzes the scientific production on aging at the Federal University of São Carlos (UFSCar) between 2004 and 2024, from the perspective of Science, Technology and Society (STS) Studies. The research, descriptive and exploratory in nature, employed bibliometric mapping and content analysis to examine 240 dissertations and theses from the institutional repository. Variables such as graduate program, advising, keywords, funding, citations, and the Applied Orientation Index (AOI) — a metric adapted from Technology Readiness Levels (TRL) — were analyzed. The results reveal a substantial body of production, yet heavily concentrated in the health sciences: 74% of advisors have original training in the field, and three programs (Physical Therapy, Nursing, and Gerontology) account for 70% of funded publications. The average AOI of 2.1 indicates a predominantly diagnostic character, with low applied orientation. Interdisciplinarity remains incipient — the co-supervision rate between different programs is only 27.5%, and keyword analysis reveals that each program addresses aging from its own disciplinary silo without epistemic integration. Only 35% of publications received citations in Google Scholar. The STS analysis highlights the persistence of the linear innovation model, the concentration of funding as a dispositif of governmentality, and the need for institutional policies that promote genuine interdisciplinarity, epistemic diversity, and the transition from diagnostic production to stages of development and social impact.

This thesis produces and investigates the encounter between collage and ecosophy in science education, taking collage as a material, relational, and thought-based practice. It begins by problematizing modes of organization of school scientific knowledge that privilege representation, explanation, classification, and the stability of meaning, often separating body and thought, science and art, nature and culture, subject and world. Inspired by Félix Guattari’s ecosophy, by approximations with cartography, and by montage as an operation of thought derived from Georges Didi-Huberman, the research follows workshops with students from basic education, undergraduate teacher education, and graduate studies, an extension course, fabulated scenes, and artistic productions developed throughout the investigative process. The thesis is constructed through montages between not-so-invented memories, images, conceptual fragments, and formative experiences. By working with remnants, tears, displaced scientific images, dismantled textbooks, and collective compositions, the thesis follows what emerges when collage traverses stabilized ways of learning and organizing school scientific knowledge. In this movement, montage operates as a procedure that brings heterogeneous fragments together without reducing them to an explanatory unity, allowing knowledge production to be conceived through intervals, frictions, and provisional recompositions. As a contribution, the thesis proposes understanding collage as a situated ecosophical practice, capable of opening small recompositions between subjectivity, collectivity, and environment, tensioning ways of knowing and inhabiting educational spaces in science education.

This study critically examines the Brazilian digital economy through the case of the data center linked to TikTok/ByteDance in Caucaia (Ceará), within the Pecém Industrial and Port Complex. It argues that the concept of surveillance capitalism, formulated by Zuboff and centered on behavioral surplus and the erosion of individual freedom, is insufficient to grasp the digital economy in peripheral contexts shaped by a historical-colonial legacy and dependent integration. The aim is to examine the limits of this concept and to articulate data colonialism, as proposed by Couldry and Mejias, with the notion of double plunder — the overlap between the informational extraction of data, attention, and behavior and the material appropriation of energy, water, and territory required by digital infrastructure. A qualitative approach is adopted along three axes: a critical literature review that situates the data economy within the materiality of the network society and reinscribes it in the Latin American tradition of neo-extractivism and dependency; a documentary analysis of the policy promoting data centers, notably REDATA (Provisional Measure No.,318/2025, reintroduced as Bill No. 278/2026); and a case study of the Caucaia sociotechnical controversy, reconstructed from news reports, corporate statements, regulatory acts, and the positions of the Federal Public Prosecutor's Office, the Public Defender's Office, and the Indigenous Anacé people. The analysis shows that the physical presence of infrastructure does not amount to sovereignty: designed for a single transnational client, AI training for global workloads, and data export, the project concentrates technical command and value capture outside the country, while the water, energy, territorial, and fiscal costs remain localized in a region of structural drought and on land claimed by the Anacé. It concludes that, without public governance, control over data, and effective socioenvironmental safeguards, the policy of attracting data centers tends to consolidate Brazil as a "backyard for data centers" of the Global North, renewing its peripheral position in the international division of data infrastructure and production.

Em sistemas operacionais complexos, a latência inerente entre a ocorrência de um evento e o seu registro oficial cria vulnerabilidades estruturais severas. Esta tese explora a fundação probabilística compartilhada entre atrasos de notificação epidemiológica e a latência de verificação financeira, reconhecendo ambos como problemas de agregação de probabilidades condicionais heterogêneas sob censura temporal e mudanças de distribuição. Para superar os gargalos computacionais de abordagens paramétricas convencionais e as limitações de predição pontual do aprendizado de máquina padrão, esta pesquisa introduz uma metodologia unificada e escalável de nowcasting conformal. Ao sintetizar o reconhecimento de padrões não-lineares do Gradient Boosting com Conformal Prediction, a metodologia gera intervalos de predição robustos. Embora o framework utilize estruturas probabilísticas específicas para modelar a variância heteroscedástica, os limites preditivos finais mantêm uma cobertura marginal matematicamente válida, independente dessas premissas distribucionais subjacentes. A eficácia do framework é demonstrada por meio de três contribuições centrais. Primeiro, desenvolvemos os modelos ViDAS e SViDAS para estimar o cenário proporcional de vírus respiratórios, contornando a ausência sistemática de registros de testes negativos em bases de dados de saúde pública. Segundo, introduzimos uma arquitetura conformal bottom-up para o nowcasting de contagens absolutas de Síndrome Respiratória Aguda Grave (SRAG). Ao modelar a variância através de convoluções Binomiais Negativas, o framework atinge limites heteroscedásticos altamente calibrados, reduzindo o tempo de execução de horas para segundos em comparação com modelos espaço-temporais tradicionais. Finalmente, adaptamos essa arquitetura para o domínio de risco de crédito, modelando a inadimplência de portfólios via distribuição Poisson-Binomial. Durante o choque macroeconômico de 2021, o framework proposto identificou um Prior Shift estrutural no horizonte precoce de h=4 meses, corrigindo com sucesso a taxa de pico de inadimplência projetada (de 12,0% para 15,0%) com exatos 8 meses de antecedência em relação aos modelos tradicionais de 12 meses. Ao aplicar uma translação marginal de log-odds, a metodologia permite que instituições ajustem as provisões de Perda Esperada de Crédito (ECL) de maneira antecipada, preservando a ordenação de risco (rank-ordering) do modelo sem acionar ciclos rígidos de validação de retreinamento. Em suma, esta tese fornece frameworks metodológicos escaláveis — desde pipelines epidemiológicos em código aberto até aplicações avançadas de Gestão de Risco de Modelo (MRM) — que mitigam substancialmente os pontos cegos operacionais causados pela latência de informação.

This study aims to analyze manifestations of hate speech directed at women’s football, especially toward the athlete Marta Silva, observing how these statements resume historically constructed meanings about the place assigned to women in sports. The research is based on the symbolic contradiction between the consecration of a “King of football” and the difficulty in legitimizing a “Queen of football”, focusing on comments about the athlete Marta Silva on social media. As a theoretical foundation, the concepts of statement and archive by Michel Foucault, the discussions on structural sexism by Pierre Bourdieu, and the concept of technodiscourse by Marie-Anne Paveau are used. The analysis demonstrates that many comments reproduce misogynistic discourses and reinforce historical inequalities still present in women’s football.

This dissertation investigates how the LGBTQIA+ Movement constitutes itself as a collective political subject in the context of the reopening of institutional channels for participation during the third government of Luiz Inácio Lula da Silva. The analysis takes as its empirical object the 4th National Conference on the Rights of LGBTQIA+ People, encompassing its state (São Paulo) and national stages, and combines participant observation with documentary analysis of the proposals approved throughout the conference process. The study is organized around three analytical axes: the forms of political articulation among the different subjects within the movement; the demands directed toward the State; and the internal dynamics of conflict and coalition. The first chapter examines identity as a theoretical problem, drawing on queer theory, debates on identitarianism, and the historical formation of the movement’s subjects. The second chapter analyzes conflicts observed in the field, with emphasis on the expansion of subjects named by the movement, disputes surrounding intersectionality as a political grammar, and resentment as a structuring affect of internal relations, especially between gay men and other political subjects. The third chapter examines the proposals produced at the Conference, mapping demands related to institutional advocacy, labor, education, combating violence, social protection, and health, as well as the tensions and consensuses involved in constructing a common agenda. The findings indicate that the identity politics of the LGBTQIA+ Movement cannot be reduced to a fragmentary dynamic; rather, it constitutes a field of disputes in which demands for recognition and redistribution are articulated in contingent ways. The notion of contingent alliances is proposed to describe coalitions formed not from a pre-existing shared identity, but from situated negotiation among differences and the perception of partially convergent interests. By historicizing the movement’s internal tensions and analyzing how resentment simultaneously fractures and fuels political mobilization, the research contributes to questioning interpretations that associate identity politics with the fragmentation of the progressive political field.

The application of composite materials has expanded across various areas of modern industry, driven by the search for lighter and stronger components. These materials exhibit characteristics such as high specific stiffness, corrosion resistance, and low mass, making them attractive to sectors such as automotive, naval, sports, wind energy, and biomedical segments. However, it is in the aeronautical industry that composite materials have the most significant use, being employed in the manufacture of fuselages, wings, and internal components, with the main purpose of reducing the total weight of aircraft, promoting greater fuel efficiency, increased flight range, and reduced emissions. The processing of these materials is largely carried out by CNC machining centers, equipped with cutting tools developed to handle the abrasiveness and heterogeneity of composites. Such tools have high development and acquisition costs and are subject to accelerated wear during the process, which reinforces the need for strategies that allow for maximum utilization of their service life without compromising the quality and integrity of the final product. In this context, this study proposes monitoring the condition of cutting tools through a combination of direct and indirect methods. The direct method employs geometric characterization of the cutting edges of the tools using microscopy, while the indirect method utilizes the analysis of mechanical vibrations captured by sensors integrated into the CNC machine spindle. The methodology consists of the periodic collection of vibration signals throughout the tool lifespan, followed by analysis of the cutting edge condition through microscopic image analysis. The correlation between vibration levels and wear conditions observed in the microscopy analyses highlights the potential for using this information together to build a predictive model for estimating the optimal tool usage time, contributing to greater production efficiency.

This thesis investigates key challenges to the success of ecological restoration in the context of climate change, integrating two complementary dimensions: the assessment of monitoring in restored areas and the selection of species that are more resilient to extreme climatic events. In the first chapter, the study critically analyzed the capacity of the monitoring model established by SMA Resolution No. 32/2014 to adequately represent the ecological condition of restoration projects when results are aggregated at the project level. Based on data from 12 projects distributed across 453 polygons in the Promissão Reservoir region, along the Tietê River (São Paulo State, Brazil), the study demonstrated high spatial heterogeneity in the legal indicators and highlighted the risk of masking critical areas, which may compromise the evaluation of legal compliance. In the second chapter, the thesis investigated how functional traits of plant species, such as leaf thickness, the presence of trichomes, and crown shape, influence frost tolerance in restoration areas, providing support for the selection of species better adapted to adverse climatic conditions. Taken together, the results show that restoration effectiveness depends both on monitoring criteria that are more sensitive to ecological variability and on the incorporation of species-selection strategies capable of increasing the resilience of restored plantings to extreme events. The thesis therefore contributes to the technical and scientific advancement of ecological restoration, with practical implications for planning, monitoring, and the formulation of public policies in Brazil.

Tupiniquim
Understanding contemporary environmental dynamics requires a complex systems perspective, in which the environment is conceived as a network of multiple interconnected components. The Tupiniquim Indigenous Territory, located in Aracruz, Espírito Santo, Brazil, exemplifies this complexity due to its intense historical and spatial transformations. This study aims to examine the dynamics between society and nature within this territory through a spatiotemporal assessment of environmental quality and quality-of-life indicators. The methodological approach was based on the Pressure–State–Response (PSR) framework, focusing exclusively on state indicators. Geographic Matrix analysis and Geographic Information Systems (GIS) were employed to conduct a comparative assessment of Brazilian Institute of Geography and Statistics (IBGE) census data from 2010 and 2022. The results revealed an uneven evolution in the provision of infrastructure and basic services across the territory. Water supply coverage through the public distribution network and solid waste collection services expanded substantially in several census sectors. However, public sewage network coverage remained limited or absent in most areas, reinforcing reliance on inadequate sanitation solutions. In the socioeducational dimension, the data indicated a percentage decline in literacy rates. This apparent decline primarily resulted from the methodological fragmentation of the territory in the 2022 Census, which increased the number of census sectors from seven to sixteen. This change improved the spatial resolution of the survey and exposed areas of long-standing vulnerability. In addition, intensive land-use classes, particularly mixed-use mosaics and pasturelands, expanded at the expense of native vegetation. The findings indicate that strengthening sustainability in the region requires the implementation of integrated territorial management strategies capable of promoting equitable access to basic services while addressing the urgent need for environmental conservation. Such measures are essential to safeguarding the autonomy, social cohesion, and cultural identity of Indigenous peoples.

BAJA SAE vehicles operate in adverse off-road environments, subject to vibrations, impacts, and large distances from reference stations, which makes real-time monitoring challenging with conventional wireless communication technologies that impose significant range and robustness limitations. In this context, this work presents the development and experimental validation of an embedded monitoring and telemetry system for BAJA SAE vehicles, based on LoRa communication and Real-Time Operating System (RTOS) task management. The proposed system consists of a custom printed circuit board designed for the acquisition of engine rotational speed, vehicle speed, continuously variable transmission (CVT) temperature, and triaxial acceleration data, using Hall-effect sensors (A3144), a Type-K thermocouple with MAX6675 interface, and an MPU6050 accelerometer. Data processing is performed by an ESP32 microcontroller running FreeRTOS, with task distribution across its dual-core architecture to ensure efficient real-time operation. Wireless data transmission is carried out through the E220-900T22D LoRa module operating at 915 MHz, while local data logging is implemented through an SD card interface. Experimental validation demonstrated temperature measurement error within the manufacturerspecified tolerance of approximately 2 °C, coherent sensor responses for rotational speed and vehicle speed with minor delay and damping effects, and proper accelerometer operation for gravitational acceleration detection. Field tests of the LoRa communication link confirmed compliance with the 500 m range requirement imposed by BAJA competition conditions. Sending 18 bytes, it achieved packet loss rates below 5% and -85 dBm received signal strength at this distance using omnidirectional 6 dBi antennas. The results validate the proposed architecture and demonstrate its technical feasibility for real-time telemetry applications in BAJA SAE competitions.

The integration of digital information and communication technologies (ICTs) into teaching and learning processes in Youth and Adult Education (EJA) is an ethical and urgent issue, given the structuring nature of ICTs in contemporary society, within a context of profound inequalities. The general objective of this research was to contribute to the understanding of possibilities for integrating ICTs into teaching and learning processes with young people and adults, starting from the teacher's perspective and aiming for a dialogical education. The specific objectives were: i) to investigate educational public policies adopted by municipalities in the state of São Paulo during the COVID-19 pandemic regarding the use of ICTs; ii) to identify the uses of ICTs in the daily lives of teachers in pedagogical practices before the pandemic, during the period of remote activities, and upon returning to in-person activities; iii) to recognize the dialogical use of ICTs in pedagogical practices in EJA. The theoretical framework was anchored in Paulo Freire's constructs that focus on dialogical and emancipatory education, as well as in authors who propose the integration of ICTs into basic education based on the contributions of dialectical materialism. To this end, a qualitative research study was conducted, of a bibliographic, documentary, and empirical nature, with fourteen teachers from twelve municipalities in the state of São Paulo. In the field research, the instruments used were an on-line questionnaire and a semi-structured interview. As a result, we identified that during the pandemic, the education departments of the municipalities analyzed did not provide adequate infrastructure for the development of teaching work in relation to the use of ICT during the period of emergency remote teaching (ERT); upon returning to in-person activities, there was an increase in the use of digital technologies, both in terms of frequency and types of devices; and finally, beyond the integration of ICT into teaching and learning processes, the participants in this study were dialogical in their pedagogical practices with the use of ICT, in search of the unprecedented viable.

This dissertation investigates the application of the Lean methodology in several Higher Education Institutions (HEIs), combining a systematic literature review with a proposal for practical implementation in the diploma issuance process at a public university. Given the growing interest in the application of Lean and Lean Six Sigma (LSS) in service environments, including the educational sector, this work aims to identify processes that benefit from its application, the tools used, the barriers faced, and strategies for overcoming them. The first stage consisted of a Systematic Literature Review (SLR), conducted in the Scopus and Web of Science databases, resulting in the analysis of 88 articles, of which 48 empirical studies were selected to answer the research questions. The analysis allowed for mapping the areas of application, the types of projects developed, the most frequently used tools, and the adjustments made for the context of HEIs. The second stage proposes the application of Lean in the undergraduate diploma issuance process, using a case study in a public HEI, seeking to evaluate gains in efficiency, response time, and waste reduction. This research contributes to the consolidation of knowledge about Lean in higher education, especially in the public sector, and provides support for managers interested in improving academic and administrative processes in HEIs.

This article discusses the relationships between democracy, scientific communication, and the arts, analyzing how artistic practices can function as forms of mediation, humanization, and democratization of knowledge in contemporary contexts marked by structural inequalities and the logic of digital platforms. Drawing on an interdisciplinary approach, it brings together contributions from communication studies, sociology, philosophy, anthropology, and critical education to examine the effects of contemporary capitalism on emotions, knowledge production processes, and regimes of symbolic circulation. The text mobilizes the song “Marujo” by the band Puro Suco, as well as elements of Brazilian popular culture, especially the figure of Iara, as metaphors for the experience of knowledge understood as a collective journey, traversed by tensions, displacements, and possibilities of social transformation. It argues that scientific communication must move beyond strictly technical models, incorporating cultural, aesthetic, and emotional dimensions capable of broadening access to knowledge, strengthening democratic practices, and fostering more inclusive forms of social participation.

This study investigates the hypothesis that the use of Twitter/X contributes to the intensification of political polarization in Brazil by fostering the formation of ideological bubbles and the circulation of polarized content. Its main objective is to analyze how the platform’s algorithmic architecture influences the quality of public debate and democratic foundations within the Brazilian context. The research adopts a qualitative and interpretive approach, based on a bibliographic review of national and international academic literature in the fields of political communication, digital platforms, democracy, and polarization. The discussion is grounded in the concept of surveillance capitalism to understand how algorithmic personalization and the attention economy encourage homogeneous information environments, often referred to as echo chambers. The findings indicate that Twitter/X acts as a catalyst for political polarization by privileging emotionally engaging content and facilitating the circulation of polarized and disinformative narratives. It is concluded that the platform significantly contributes to the strengthening of rigid political identities and to the fragmentation of the democratic public sphere.
