This research investigated the instruments and methodological procedures necessary for the development of the higher psychological functions of voluntary attention and the formation of scientific concepts in six-year-old children during Physical Education classes. This study was supported by Historical-Cultural Theory, which postulates that human development is shaped by social interactions, language, and the appropriation of culture in a given historical context. The theory's principles are: the development of the human mind through the appropriation of historically constituted social forms of human activity, effective activity appropriate to the individual, and the development of higher psychological functions that foster self-control and self-mastery. The research aimed: to develop instruments and methodological procedures inherent to the development of the psychological functions of voluntary attention and the formation of scientific concepts, using social role-playing and table/board games; to develop a pedagogical intervention experiment based on the learning needs of the target people; and to discuss the effectiveness of the methodological instrument applied. They used the following methodological instruments: a pedagogical intervention experiment with systematic and participant observation and structured activities aligned with the fundamentals of Historical-Cultural Theory; activities consisting of body tracking and board tracking, human chess and board chess, laterality games, and social role games, to promote social interaction. For systematic observations, we used video recordings and a field diary. The results showed that, in the pedagogical intervention experiment, the integration of bodily experiences and symbolic games favored the development of voluntary attention and scientific concepts, especially when they are mediated by language and conscious action. We emphasize the role of "affinity groups" in organizing relationships among students, which required intentionality on the part of the researcher to foster meaningful mediating activities for learning. The results also showed that the transposition from the concrete to the abstract proved effective, especially when it is anchored in bodily experience. We concluded that intentional pedagogical environments, structured with social role-playing and table/board games, significantly favored the development of voluntary attention and the formation of scientific concepts in six-year-old children. Planned teacher mediation, based on the Action Guiding Framework and levels of assistance, proved effective in promoting the conscious and autonomous internalization of learning, reaffirming the principles of Historical-Cultural Theory and contributing with new perspectives to pedagogical practice in Physical Education.

Scientific dissemination provides non-specialist citizens with the opportunity to effectively participate in public debates, decision-making, and conscious choices in their daily lives, through inputs provided by the circulation and cognition of contextualized scientific information. In this area, social media stands out by moving from being a source of entertainment to becoming a source of information. TikTok, the object of analysis of this research, stands out as a potential channel for scientific dissemination and has been used by influencers and researchers who are able to quickly approach scientific information for young users who seek content on this platform, often to the detriment of traditional sources of information. This descriptiveexploratory research with quantitative and qualitative approaches has the general objective of investigating Brazilian digital influencers (researchers) who use TikTok for scientific dissemination and analyzing the content (topics) they address. To structure the research, a bibliographic survey was carried out to compose the theoretical framework and select science TikTokers (researchers) – the latter action was carried out in search engines and on the platform itself (TikTok), based on a previous protocol. An alternative model of Bardin's content analysis was applied to collect and analyze the data. The interpretation of the 407 published contents shows that the scientific dissemination model applied on the platform can affect the development of information practices and media competence of followers who consume scientific information. It was clear that not all TikTokers invest in sharing information with references/sources, reducing the possibility of followers developing an interest in the topic/subject outside the platform. When analyzing the content of the TikTokers investigated, it was observed that the narrative structure is maintained to share more contextualized scientific information, especially that categorized as curiosities. Digital influencers, by acting as mediators of scientific knowledge, can play an important role in the democratization of information and in strengthening scientific literacy in digital environments.

This study examines Critical-Transformative Environmental Education through the Generative Theme approach (EACT-TG), as proposed by Torres (2010), investigating its theoretical foundations and its application in the analysis of the “Currículo Paulista” (São Paulo, 2019) for the final years of elementary education. The research begins by reviewing the main curriculum theories, categorized by Silva (2016) into Traditional, Critical, and Post-Critical approaches, and enriched by contributions from other relevant scholars. The focus then shifts to the concept of the environment, discussing socially constructed representations (Naturalist, Anthropocentric, and Globalizing) as defined by Reigota (2010), along with a brief history of the environmental movement and Environmental Education (EE) in Brazil. The study also explores the major trends in EE (Conservationist, Pragmatic, and Critical), systematized by Layrargues and Lima (2014), emphasizing the principles of Critical Environmental Education (CEE) and its connection to Paulo Freire’s Pedagogy of Liberation. A brief biography of Freire is presented, highlighting his contributions to education, such as dialogue, problem-posing, and generative themes, which underpin the EACT-TG approach. The methodology is qualitative, with an emphasis on bibliographic research and document analysis, understanding research as a reflective and dialogical process influenced by and influencing social life. Finally, the study conducts an in-depth analysis of how the theme of the environment is addressed in the “Currículo Paulista” for the final years of elementary education, using the core principles of EACT-TG (Dialogue and Problematization toward Awareness) as analytical parameters. The theoretical framework confirms that EACT-TG aims not only at environmental awareness but also at transforming the sociocultural and material relations of concrete reality, thereby providing a foundation for data analysis. The comparative analysis between the “Currículo Paulista” (São Paulo, 2019) and the principles of EACT-TG indicates that the curriculum reveals more divergences than alignments, limiting its emancipatory potential. Although the curriculum acknowledges the cross-cutting nature of environmental issues, it addresses the theme superficially, without incorporating students’ lived experiences or questioning the structural causes of environmental crises. Its emphasis on individual actions and prescriptive nature restricts teacher autonomy and distances the curriculum from a critical and transformative educational approach, as envisioned by Freirean principles.

In a context of continuous adaptation of football to business modes of management, neoliberalism, interpreted as a rationality, aims to produce a new football culture. This research aimed to understand how the discourses and practices of this football-business have been produced, reproduced and elaborated by different groups of agents of Brazilian football. To fulfill this objective, the research carried out documentary analysis from various sources, produced directly and indirectly by investment agencies focused on sports analysis, specialized press, club leaders and fan sectors in Brazil. It was observed how neoliberal rationality had an impact on different aspects of Brazilian football. At its discursive level, the business language is widely reproduced in an uncritical way, especially among sports journalists and club leaders, but also among sectors of the fans. On an organizational level, the advent of the SAF materialized the neoliberal solution to the crisis of the associative clubs, establishing itself as a business and management model to be copied. It was also found that new fan subjectivities have been molded with the objective of producing a fan-consumer subject adapted to this new football culture. It is concluded that, with the focus on the suppression of politics, perceived as the activity capable of producing tensions to an established order, neoliberalism has managed to establish itself, until this moment, as the hegemonic order in the football field

Inoculation of cultivars with diazotrophic bacteria such as Azospirillum brasilense can make crops more productive and sustainable, since it reduces the need for nitrogenous chemical fertilizers. However, it is necessary to develop bioinoculant formulations that maintain cell viability for long periods and provide protection against biotic and abiotic stresses. Osmotic, saline, radiation and temperature stresses represent challenges for the prevalence of A. brasilense cells in soil. As an alternative to this problem, the aim is to encapsulate A. brasilense cells in biodegradable matrices through the ionotropic gelation method, characterize the material and assess cell viability during storage. The method consists of forming macrobeads of the matrices containing the microorganism, through the dripping and crosslinking of a polymeric dispersion in a FeCl3 solution. The material chosen was carboxymethyl cellulose (CMC) because it is a renewable, abundant and commercial material and trehalose because of its thermal protection capacity. Beads with a fixed amount of 2.5% CMC and 4 treatments containing 0%, 1%, 5% and 10% trehalose were produced and stored moist at 4 °C and 25 °C; and after drying at 25 °C. The CMC capsules without trehalose showed higher encapsulation efficiency and better viability up to the 15th day of storage at 25 °C. FTIR analysis evidenced the formation of the chemical structure of CMC crosslinking with Fe³⁺, and SEM analysis revealed a regular surface of the spheres. However, the formulation of Azospirillum inoculants requires further investigation, particularly regarding the optimal concentrations of CMC and trehalose and their influence on matrix stability and cell survival during prolonged storage.

The advancement of the Internet has resulted in an increase in the continuous generation of data, raising the risks of damage caused by cyber threats. Firewalls play a crucial role in network security by providing protection against these threats. They operate by organizing log records based on specific rules, considering criteria such as the purpose of connections and the policies established by the organization. Updating these rules is challenging, and inadequate choices can lead to security vulnerabilities. Related work on predicting recommended actions for network traffic still employs traditional machine learning methods, where the dataset is static and can be repeatedly traversed, while detecting new patterns requires a new cycle of training, testing, and implementing new models. However, network traffic is continuously captured by a firewall, and its behavior can change both abruptly and gradually. This is common in network environments, where it is necessary to adapt to frequent changes in security policies, network modifications, or new threats. This work proposes the application of the MINAS and Adapted CluStream algorithms to predict recommended actions in network traffic. The logs consist of sessions of network traffic captured by a firewall from an educational institution. Adaptation is necessary for these algorithms to classify the recommended actions (Allow, Deny, Drop, and ResetBoth) in a data stream scenario. CluStream is an incremental algorithm, while MINAS, besides being incremental, specializes in novelty detection. Both algorithms were selected for their specificities and capabilities in learning and evolving the model as new data arrives from the data stream. Experiments conducted demonstrate that both algorithms showed distinct results in the data stream, with satisfactory performance across different metrics throughout the experiments.

In this work, the assembly of an electrochemical system coupled to a conventional microwave oven was optimized to investigate its feasibility for reproducible microwave-assisted electrochemistry. The study addressed the influence of the main system variables, such as the height of the electrode inside the microwave cavity, the electrolyte concentration, and the solution temperature, on the variation of the open-circuit potential during 7 s microwave pulses. The cleanliness of the system components was verified by cyclic voltammetry, and the solution resistance was evaluated by EIS. Several tools were specifically developed for this system, including custom-machined Teflon flow tubes and a laser positioner with magnetic mounting. The experiments performed using a 23 factorial design were successful mainly due to the reduction of the microwave oven’s input voltage, which prevented electrical arcing that previously damaged the system. The results showed that electrode height and electrolyte concentration are significant factors in the electrochemical response, contributing to a localized increase in temperature at the electrode surface. Comparison with computational simulations confirmed the validity of the experimentally observed trends, aligning with previous findings and demonstrating the effectiveness of the system in providing localized thermal assistance during electrochemical experiments. This study opens new possibilities for the application of microwaves in electrochemistry, presenting a simpler and more reproducible assembly method compared with those previously described in the literature.

Recent estimates indicate that the housing deficit in Brazil exceeds 6 million dwellings, driven by increasing urban population concentration and growing barriers to homeownership. This dissertation analyzes the methodology for calculating the housing deficit developed by the João Pinheiro Foundation (FJP), focusing on its application at the intracity scale. The research acknowledges the institutional relevance of this methodology but questions its conceptual, operational, and political limitations, especially in light of the socio-spatial inequalities that characterize Brazilian cities. The objective is to critically examine the FJP methodology using a qualitative and multiscalar approach, based on secondary data from the 2010 Demographic Census and local surveys conducted in the municipality of Jacareí-SP. The methodological framework includes a review of the housing deficit concept, a theoretical analysis of the FJP methodology, and its practical application to census microdata. The results indicate that the housing deficit is not a neutral absence, but a normative construct that determines who is or is not recognized as a subject of public policy. The analysis revealed limitations in the methodology when applied at the intermunicipal level - particularly through the use of census weighting areas - which obscures internal inequalities and phenomena such as overcrowding, excessive housing cost burden, and inadequate sanitation. The research also incorporated a sociodemographic and infrastructure analysis of deficit households, deepening the diagnostic beyond absolute housing numbers. The limitations encountered - such as the unavailability of 2022 census microdata and the rigidity of official tools - did not compromise the analysis, but rather reinforced the critique of relying solely on census data for urban planning. The study concludes that it is urgent to develop local strategies for housing monitoring based on integrated, multiscalar, and territory-sensitive approaches. This dissertation thus seeks to contribute to the improvement of housing public policies, grounded in fairer, more sensitive, and territorially qualified diagnostics.

Soil carbon stock is a crucial indicator of soil health and an important component of climate‑change mitigation, being directly influenced by land‑use and management practices. Low‑carbon agriculture seeks to reconcile food production with environmental sustainability, aligning with commitments to reduce greenhouse‑gas emissions. This study primarily aimed to evaluate the spatial variability of soil carbon stock (SCS) in the 0–60 cm layer among Integrated Livestock–Forest (IPF), Cropland, and Pasture systems, and to analyze the relationship between total carbon and soil physicochemical variables. Soil samples were collected at depths of 0–20, 20–40, and 40–60 cm, and analyses were performed to determine a range of physicochemical attributes. Principal Component Analysis (PCA) was used to identify the attributes that most contributed to variability in soil properties among management systems. Subsequently, Spearman’s correlation analysis was applied to test the association between total carbon and soil attributes within each system. Means of soil carbon stock were statistically compared using the nonparametric Mann–Whitney test (p < 0.05). PCA results indicated that attributes such as aluminum saturation, exchangeable aluminum, organic matter (OM), pH, and base cations (calcium, magnesium, potassium), in addition to textural fractions and sulfur, were the main determinants of variability in soil attributes across the evaluated systems. The correlation analysis showed that OM had the strongest positive and significant correlation with total carbon in all managements (IPF, Cropland, and Pasture). In contrast, aluminum and aluminum saturation consistently displayed negative correlations with carbon. Correlations for other attributes varied among systems: sand correlated negatively in Cropland and Pasture but not in IPF, and potassium showed no significant correlation in Pasture. For soil carbon stocks (0–60 cm), Cropland had the highest mean (117.22 t ha⁻¹), followed by IPF (107.5 t ha⁻¹) and Pasture (93.17 t ha⁻¹), revealing that SCS differs statistically among systems, depending on management and each area’s physicochemical characteristics. Cropland and IPF systems demonstrated greater potential to maintain or increase soil carbon compared with Pasture in the study area. Organic matter is the primary factor influencing soil carbon stock across all managements, reinforcing the importance of agricultural practices aimed at building OM for the sustainability of agroecosystems.

Background: Temporomandibular disorder (TMD) is a complex musculoskeletal condition often causes orofacial pain, functional limitations, and otological symptoms. Specific cervical exercises and manual therapy are widely used strategies for managing TMD-related symptoms; however, their effects on otologic symptoms remain unclear. Aerobic exercise, despite its therapeutic potential for musculoskeletal pain, is still underexplored in this population. Objectives: This thesis investigated the effectiveness and clinical relevance of physiotherapy interventions involving manual therapy and specific cervical exercises, alone or in combination with aerobic training, on orofacial pain, neck disability, and otological symptoms in women with chronic TMD. The specific aims were: (1) to analyze the effectiveness of manual therapy and therapeutic exercises on otologic symptoms in individuals with TMD through a systematic review (Article 1); (2) to evaluate the additional effects of aerobic training to cervical exercises on orofacial pain, neck disability, and related outcomes in a randomized controlled trial (Article 2); (3) to assess whether otological symptoms secondary to TMD improve after isolated cervical exercises or combined with aerobic training (Article 3); and (4) to determine the clinical relevance of the effects of these interventions using distribution- and anchor-based methods, with a focus on the minimal important difference (MID) (Article 4). Methods: The thesis comprised a systematic review and a randomized controlled trial. The systematic review included studies that evaluated the effects of manual therapy and exercises on otological symptoms in individuals with TMD, with certainty of evidence assessed using the GRADE approach. The randomized controlled trial enrolled 58 women with chronic TMD, allocated to two groups: (1) cervical exercises (strengthening and stretching of flexors, extensors, and rotators, and spinal mobility) and (2) cervical exercises combined with aerobic treadmill training. The intervention lasted eight weeks, with two sessions per week. Outcomes included orofacial pain, neck disability, otological symptoms, mandibular function, oral health-related quality of life, self-efficacy, and pressure pain thresholds of masticatory and cervical muscles. Statistical analyses included repeated-measures models, multilevel modeling (MLM), and estimation of the MID using distribution- and anchor-based methods. Results: The systematic review found that combining exercises with manual therapy may improve otological symptoms in individuals with TMD, but the certainty of evidence was low. In the clinical trial, no statistically significant differences were found between groups. However, both groups showed significant within-group improvements in pain, neck disability, otological symptoms, mandibular function, quality of life, and self-efficacy. Effect sizes were generally larger in the group that combined cervical and aerobic exercises. Otological symptoms significantly decreased in both groups, with clinically relevant reductions, particularly for tinnitus, earache, and ear fullness. Clinical relevance analysis showed that between-group differences did not reach the MID thresholds, whereas within-group effects were moderate to large. MID values ranged from 17.05 to 31.56 mm for pain intensity, and from 1.04 to 3.41 points for neck disability. Conclusion: Combining exercises with manual therapy may improve otological symptoms in individuals with TMD, though the certainty of evidence remains low. Adding aerobic training to specific cervical exercises did not yield additional benefits in reducing orofacial pain or otological symptoms in women with TMD. This thesis provides evidence on the effectiveness of these interventions and offers clinically relevant parameters to support evidence-based practice and patient-centered decision-making.

The VIMAC3V steel, which is a variation of the High-Speed Steel M3:2 according to ASTM A600, belongs to the category of high molybdenum content High-Speed Steels (M class) and includes alloying elements such as chromium, vanadium, and tungsten. It stands out for its exceptional wear resistance combined with toughness and hot hardness, making it suitable for various industrial tools such as taps, reamers, knives, dies, and punches. However, due to the high number of precipitated carbides in the matrix, VIMAC3V steel exhibits high resistance to abrasive wear during the machining of the final tool, resulting in low grindability when compared to other steels in the same class. This limitation has the potential to negatively impact productivity and increase industrial costs. Thus, this study was divided into two parts. The first part involved the characterization of commercial steels from different suppliers. The objective of this phase was to correlate the microstructure with the best combinations of properties for the application of this material. The results obtained from the characterization of commercial steels showed finer and more homogeneously distributed carbides, as well as relevant changes in the chemical composition of the material. The second phase consisted of implementing changes in the manufacturing process of this material to obtain an optimized microstructure based on the results obtained in the first phase. The studies focused on chemical composition analysis, microstructure, carbide quantification, types of inclusions, and wear resistance. The main microstructural feature observed was the distribution of the present carbides which demonstrated a significant improvement in the distribution and size of carbides. Therefore, it was concluded that the applied changes were effective and provided insights to understand and propose improvements in the microstructure toward refined carbides.

In this PhD thesis, we investigate div-curl type estimates associated with linear partial differential operators on Hardy-Sobolev spaces. The main result establishes a local extension of div-curl estimates for elliptic homogeneous linear partial differential operators with smooth complex coefficients in localizable Hardy-Sobolev spaces, inspired by the classical result due to Coifman, Lions, Meyer and Semmes. This version recovers known results in the literature concerning first-order operators associated with elliptic systems of complex vector fields. As key tools, we develop a new Calderón-Zygmund decomposition and a Poincaré-type inequality in localizable Hardy-Sobolev spaces. A second main result presents a global nonhomogeneous version of div-curl type estimates in the localizable Hardy space for p = 1, associated with complex vector fields with constant coefficients. As an application, we provide a new characterization of the local bmo space in Euclidean space associated with div-curl terms.

Printed Circuit Boards (PCBs) are important components of electrical and electronic equipment. Due to their composition, which includes materials of high value as well as others with potential hazards to the environment and human health, they have become the focus of growing concern. The present work analyzed strategies for end-of-life management of printed circuit boards (PCBs) in Brazil, integrating a systematic literature review, modeling for the prediction of waste electrical and electronic equipment (WEEE), and scenario assessment using Life Cycle Assessment (LCA). The significant increase in publications addressing hydrometallurgical methods for metal recovery from PCBs has highlighted the potential for sending them to recycling processes. However, gaps such as recovery processes through biometallurgy and the management of reverse logistics still need to be explored, pointing to opportunities for future research. Forecasting WEEE generation in Latin America proved to be essential, where per capita GDP and Human Development Index (HDI) were used as variables. The generated model showed that economic and social development directly impact the quantity of waste generated, reinforcing the importance of specific public policies for the management of WEEE reverse logistics. The possible end-of-life scenarios for PCBs were evaluated using the LCA technique, and the results indicated that a recycling plant in Brazil, based on the acidic hydrometallurgical method, would be the most sustainable solution among the scenarios evaluated. The recovery of precious metals, such as gold and palladium, proved to be fundamental for reducing environmental impacts and generating economic value by reinserting materials into the production cycle, while processing in Brazil minimizes the impacts associated with transport to other countries, as currently occurs. This work contributes to the advancement of sustainable management of reverse logistics of electronic waste by providing well-founded support for public policies and business initiatives, reinforcing the importance of regional strategies and investments in innovative technologies to promote a circular economy.

The search for sustainability has become an essential condition for the preservation of life. Climate change and natural disasters have increasingly highlighted the urgency of balancing development and environmental conservation, which has led the Brazilian government to expand its legal framework and invest in programs aimed at raising awareness and mitigating adverse impacts.The Environmental Agenda in Public Administration (A3P) is a program created by the Ministry of the Environment, which aims to encourage public agencies in the country to implement sustainability practices. Considering the importance of Higher Education Institutions (HEIs) in the production and dissemination of knowledge, as well as their social influence, this research aims to investigate the theme of environmental management on the campuses of the Federal Institute of São Paulo (IFSP), conducting an analysis of the sustainable actions implemented on the different campuses of the institution based on the axs that make up the Environmental Agenda in Public Administration (A3P). The research is classified as exploratory and descriptive, with a quantitative approach, outlined as a survey, of an applied nature. Data collection was conducted thru the application of a questionnaire and supplemented by documentary research and the gathering of information from the IFSP campuses' websites. The research results indicate that the IFSP campuses that participated in the study partially comply with the guidelines proposed by the Environmental Agenda in Public Administration. However, some challenges need to be faced, especially regarding the consolidation and awareness of sustainability committees, as well as the adoption, in the different campuses of the institution, of the actions and events of good environmental practices proposed by the IFSP Sustainability Plan.

Changes in rainfall can affect the structure of ecological communities, influencing the interactions amongst trophic levels. In terrestrial tritrophic systems involving herbivores such as immature Lepidoptera, their host plants and parasitoids, these changes are very complex and hard to predict, especially in the tropical Atlantic rainforest. Since the knowledge about species distribution and seasonal patterns are necessary for conservation efforts, the main objective of this work is to evaluate the temporal variation in the community structure of immature Lepidoptera associated with Myrsine L. species and their interactions with parasitoids in an atlantic rainforest area. The study was conducted at the Reserva Biologica da Serra do Japi, in the township of Jundiaí, São Paulo state, Brazil. From March to August 2024, Immature Lepidoptera were sampled with an entomological umbrella in 33 host plants, distributed in two species of the family Primulaceae: Myrsine umbellata (N=19) and Myrsine gardneriana (N=14). The immature lepidopterans were taken to the Instituto Nacional de Ciência e Tecnologia dos Hymenoptera Parasitoides (INCT-HYMPAR) in the town of São Carlos, SP, and were kept under laboratory conditions until the emergence of Adult Lepidoptera or eventual parasitoids. The specimens were deposited at the Coleção Taxonômica do Departamento de Ecologia e Biologia Evolutiva, Universidade Federal de São Carlos, Brazil (DCBU). In total, 215 larvae of Lepidoptera were recorded, distributed in 8 families (Erebidae, Geometridae, Limacodidae, Noctuidae, Psychidae, Riodinidae, Saturniidae and Tortricidae) and 46 species and morphospecies. Phrygionis polita was the most abundant species (N=46). Richness and Diversity values were higher for the dry season and the early dry season had the higher sample coverage. Immature abundance was statistically consistent over time (p=0,86084). There was a significant variation in the species composition (p=0.0116) and the variation was mostly explained by the higher abundances of some species in the early dry season. A total of 131 parasitoids were reared, belonging to two orders (Hymenoptera and Diptera), 4 families and 19 morphospecies. A new species of the genus Colpotrochia Holmgren was recorded and described. Parasitism proportion differed between seasons and was higher in the dry season; changes in the trophic interactions were also observed. Thus, this work provides new ecological data and reinforces the importance of studies with immature Lepidoptera for conservation.

Competitive and Technological Intelligence (CTI) emerges as a methodological alternative for technology-based ventures, encompassing the collection, processing, and automated analysis of technological information from patent documents. This approach aims to capitalize on opportunities and mitigate threats in the competitive environment, effectively directing strategies. The objective of this research was to investigate the use of patent analysis by Competitive and Technological Intelligence in the context of the competitive processes of technology-based ventures. The methodology adopted is classified as a metric, exploratory, and quantitative-qualitative study, using categorical content analysis and bibliometric techniques. The sample consisted of 90 article records indexed in the Web of Science database, representing the intersection between the topics of patent analysis (6,326 documents) and competitive/technological intelligence (4,046 documents). The results achieved include a set of indicators: 1) characterization of the analyzed sample; 2) indicators on patent analysis; 3) indicators on Technological Competitive Intelligence; 4] analysis of the characteristics of patent analysis appropriation by Competitive and Technological Intelligence, including insights into trends and patterns. The conclusion is that patent analysis plays an essential role in supporting Competitive and Technological Intelligence, providing strategic information for innovation and decision-making in technology-based companies. However, the limited intersection between studies on both topics indicates the need for greater methodological integration and in-depth research on the topic. It is recommended that future research explore new analytical approaches and expand the practical application of these concepts across different industrial sectors, promoting better use of patent data in developing competitive strategies.

Since the redemocratization, public security policies in Brazil have undergone successive legal and institutional reforms, driven by recurring crises and social pressure for more effective responses to crime and violence. These transformations reflect not only conjunctural reactions but also ideological disputes regarding the roles assigned to the State, punishment, and protection in the implementation of public policies. Based on this context, the study recognizes that the post-1988 period was marked by distinct political-ideological orientations, delimiting the research timeframe between 1995 and 2022. This interval encompasses a phase of relative democratic stability and three blocks of institutional change: the liberal pattern during the governments of Fernando Henrique Cardoso, the neo-developmentalist pattern under Lula and Dilma Rousseff’s administrations, and the pattern of democratic regression observed during the governments of Michel Temer and Jair Bolsonaro. In this light, this research proposes to investigate, from the tension between the paradigms of punishment and protection, how and in which direction public security policies were modified throughout this period. The analysis combines David Garland’s (2001) typology of state models of crime control, its application to the Brazilian context by Azevedo and Cifali (2015), and the framework of gradual institutional change developed by Streeck and Thelen (2005) and systematized by Mahoney and Thelen (2010). This combined approach allows not only for identifying and classifying normative changes – from penal toughening to the approval of prevention policies and rights guarantees – but also for understanding how incremental adjustments gradually shift the axis of public policies between punitive and protective rationalities. The research integrates two complementary movements – one theoretical-historical and the other empirical – using a database of 60 approved laws, which were initially analyzed quantitatively and later subjected to qualitative content analysis, focusing on 9 laws identified as substantive policies in the field. The thesis of misalignment emerges, according to which the relationship between the ideological profile of governments and the type of policy adopted is not linear, highlighting the complexity of institutional arrangements and normative disputes shaping the public security field. Nonetheless, the study points out that public security policies primarily change through layering. The analysis seeks to reveal the ideological vectors underlying these transformations and, by demonstrating how specific normative decisions accumulate effects over time, contributes to Political Science by offering a deep understanding of the reconfiguration of the State’s role in addressing crime and insecurity management in contemporary Brazil.
