Higher education institutions continuously accumulate extensive volumes of academic data, which constitute valuable resources for understanding the behavior of students, cohorts, and academic programs. However, the growing complexity and scale of these datasets demand innovative approaches to extract meaningful insights and support strategic decision-making, such as optimizing course offerings, reducing dropout rates, and improving pedagogical practices. This dissertation proposes an approach to model students' academic journeys as complex data undergoing temporal evolution, representing them as trajectories in a metric space. Building upon this model, interactive visualization techniques are explored to analyze the academic progression of students across semesters, enabling the identification of recurring patterns, trends, and potential risk situations, such as dropout or delayed graduation. Additionally, the work introduces mechanisms to delimit and refine the data to be visualized through filtering and querying strategies, as well as trajectory summarization techniques that allow the analysis of average behaviors within customizable student groups. The proposed approach was validated through a case study involving real-world data from an undergraduate program, demonstrating its applicability and potential to support comparative analyses and inform educational management processes.

This research aims to analyze to what extent the implementation of the Articulated Action Plan (PAR) contributed to the improvement of Rural Education in the municipality of Breves-PA. The investigation is based on Historical-Dialectical Materialism, as it understands that the construction, in the light of Marxist theory, offers possibilities for understanding contradictions present in policies related to the object of study. As human production within capitalist society, such policies contain historical contradictions. To achieve the objective, specific goals were established: to study the PAR implementation policy in order to identify possible improvements for Rural Education; to analyze the results of the Active School Program for teacher training; and to identify advances for Rural Education based on PAR sub-actions between 2008 and 2022. The study was conducted through bibliographic review, document analysis, and semi-structured interviews. The time frame (2008–2022) aimed to understand both the scenario forecasted by PAR planners and the political-administrative arrangements aligned with national policy strategies. Results indicate that Rural Education in Marajó is highly heterogeneous and that standardized manuals, plans, and protocols do not address learning needs nor local demands. It is concluded that PAR should be replaced by a process enabling new debates, recognizing that municipalities must assume the role of planners and executors of their educational policy, considering the cultural and territorial diversity of Marajó and enforcing historically denied rights.

The contemporary environmental crisis transcends the ecological sphere, reflecting the exhaustion of a civilizational model based on the unrestricted exploitation of natural resources. This thesis investigates the Anthropocene as a geosocial event and its epistemological, environmental, and civilizational implications, employing prospective scenario-building of accumulated greenhouse gas (GHG) emissions to demonstrate the interconnection between geological time and social-legal-environmental time. From the perspective of Science, Technology, Society, and Environment Studies (STS-E), the premises of sustainability are critically examined, and the palliative solutions of the Capitalocene and the Carbonocene are questioned. The general objective is to problematize the Anthropocene and its instrumentalization as an ideopolitical device of climate governance. To this end, the specific objectives include: (i) analyzing the construction of the Anthropocene concept and its relationship with normative and political disputes; (ii) examining the Circular Economy and its absorption into global governance strategies; (iii) assessing economic instruments such as carbon pricing and Clean Development Mechanisms (CDMs), and their impacts on the global emissions dynamic; (iv) challenging the limits of anthropocentric sustainability; and (v) exploring the possibility of a post-sustainable paradigm. Methodologically, the research adopts a qualitative-quantitative exploratory approach, transitioning between deductive, hypothetico-deductive, and inductive methods depending on the nature of each analysis. Prospective scenario-building and GHG accounting are employed to contrast normative discourses with the materiality of climate transformations. The results demonstrate that the prevailing configuration of the Circular Economy functions as a systemic adjustment within the extractivist-linear logic rather than representing an effective rupture. Carbon pricing and the financialization of sustainability reinforce the persistence of the current economic model. Thus, the thesis moves toward the speculation of a post-sustainable paradigm, in which Ecozoicity emerges as a field of possibilities, albeit one facing structural and political challenges to its consolidation.

The research object of this thesis is the l analysis of the professional insertion of undergraduates from the Social Sciences course at the Federal University of São Carlos (UFSCar) from the course's foundation in 1991 until the year 2021.It emphasizes the profession, professional identity, and the job market. The research starts from the question of how these social scientists position themselves professionally in contemporary society and where the current trends of the profession are heading. A mixed-methodological approach was adopted, including analysis of secondary data from DIGRA (Division of Academic Management and Records) and the administration of online questionnaires to graduates. The results point to the fragmentation of the professional identity of social scientists, marked by t multiple self-designations, and to the absence of a market reserve that ensures their specialized performance. It was found that, although there is an affective appreciation of the course, especially among those who continued on to graduate school, there is a mismatch between the training received and the demands of the market, especially outside the academic environment. Social recognition of the profession is limited, and the professional trajectories of graduates reflect instability, precariousness, and interprofessional disputes. The conditions for professionalization are influenced by variables such as gender, race, and social origin, whose effects were analyzed from an intersectional perspective. A difference was also observed between the symbolic value of education—associated with broadening one's worldview and forming values—and its limited practical application in the labor market. The study dialogues with the literature on the sociology of professions, highlighting the notions of hybrid and connective professionalism, and argues that social scientists face specific challenges in a context of reconfiguration of the world of work and the expansion of neoliberal rationality. Identification and disidentification are also analyzed based on the experiences reported by the graduates participating in the study. It is concluded that, although social sciences education has subjective and political meaning for graduates, it lacks more effective institutional strategies to expand concrete possibilities for professional integration and recognition.

Non-social bees are important pollinators of natural and cultivated vegetation, such as the parasocial bees of the genus Xylocopa, which are essential for pollinating large flowers, such as yellow passion fruit, or flowers with poricidal anthers, such as tomatoes. However, the presence of these bees in agricultural crops exposes them to pesticides. Therefore, to expand knowledge about non-social native brazilian species, the objective of this thesis was to use bees Xylocopa frontalis and Xylocopa suspecta for morphological analyses of the brain and midgut. To this end, histological characterization of the main brain structures of the species X. frontalis and X. suspecta and estimation of the volume of the neuropils of the pedunculate bodies of X. frontalis bees were performed. The structures studied (mushroom bodies, optic lobes, and antennal lobes) were similar to those previously reported for other social bee species, except that the neuropil volumes of the mushroom bodies were larger than those reported for large bees. Characterization of the midguts of both bee species revealed that the cell types are similar to those observed in other bees and other organisms of the class Insecta; however, the cellular organization is unique, and this is the first report of this morphology.

This dissertation regards the theme of teaching practice in schools of the Full-Time Education Program within the state of Sao Paulo. The problem which motivated the investigation was the following: how are school climate and teaching work related in such schools? Thus, the general objective was to map the main characteristics of teaching work in PEI schools, in order to understand the relationships between school climate and teaching work in this specific context. The specific objectives were: to survey the PEI regulations in relation to teaching work; to characterize various aspects related to teaching work in schools of this program; and to relate these aspects to the factors that make up the school climate. This is a bibliographic study, in the time frame from 2018 to 2024, in the digital databases SciELO (Brazil), the Brazilian Digital Library of Theses and Dissertations – BDTD, CAPES Portal and the Google Scholar search engine. Thus, it was possible to produce a summary on the relationship between school climate and teaching work in those schools that can contribute both, to advances in studies on school administration and to enlarge knowledge about the teachers’ life quality in this specific context. In order to understand the configuration of teaching work, content analysis was used using the MAXQDA 22 software. This tool allows an in-depth exploration of the selected texts, allowing the visualization and organization of information in an adequate manner. Through this analysis, graphs and tables were generated that illustrate the main trends and categories emerging from the data. The incidence of codes, which is presented in the fifth part of this dissertation, provides a comprehensive understanding of the aspects of teaching work, highlighting both the difficulties and the potential faced by educators. This systematic approach aimed at enriching the academic debate on Teaching Work in the context of full-time schools, a topic that is still little explored, and, possibly, contribute to improving this work, considering the school climate and the quality of life and work of teachers, in addition to improving teaching-learning processes.

Disorganized urban growth has generated negative impacts in cities, such as environmental degradation and lack of infrastructure, directly affecting health, quality of life and sustainable development. These conditions can be assessed using indicators, which facilitate analysis using numerical values. The aim of this study was to propose a method for assessing urban sustainability, vulnerability and resilience in the municipalities of Water Resources Management Unit 12 (UGRHI 12), corresponding to the Baixo Pardo/Grande River Basin, using a scale of 0 to 1. The Environmental Health Indicator (ISA), the Sustainable City Development Index (IDSC) and ABNT NBR ISO 37120:2021 Sustainable cities and communities – Indicators for urban services and quality of life, were applied. In the ISA, the Water Supply and Water Resources indicators showed salubrious to average results. The Sanitary Sewage indicator showed that 58% of the municipalities are healthy and sustainable, while only four municipalities achieved an average level for Solid Waste. Vector control was critical in two municipalities (17%) and all of them were deficient in socio-economic terms. As for the Sustainable Development Goals (SDG), the results were mostly average and high, but there was poor performance in SDGs 9, 15 and 17 in all municipalities. In general, the basin has average health and sustainability, requiring investment and planning to improve indicators and quality of life. With regard to NBR ISO 37120, 13 indicators were identified, the average of which showed that 83% of the municipalities are advancing in sustainability and resilience, although some points require attention, such as daily per capita water consumption, which highlighted the need for conscious use. The main limitation was the difficulty in obtaining data, which prevented a complete analysis. In subsequent searches, 41 of the standard's 128 indicators were found (32%). To consolidate the proposed method, called the Index of Sustainability, Vulnerability and Urban Resilience (ISVRU), 10 indicators from the IDSC were selected, giving a total of 51 indicators, classified under the 17 SDGs. The ISVRU is based on the arithmetic average per SDG and the weighted average of the three dimensions analyzed. There was a great lack of programs aimed at sustainable urban planning, which reinforces the need for the Basin Committee to promote actions and debates to improve urban services, quality of life and environmental preservation.

This study was conducted based on a literature search based on the Freirean conceptual framework, in compliance with the requirements for the award of a degree in Education at the Federal University of São Carlos. The research topic is school knowledge from the perspective of Freire. Its goal is to reveal and clarify the theoretical principles for the creation of a curriculum that promotes quality education in society. The central question of this study was: which principles, guided by Paulo Freire's pedagogy, can guide the creation of a curriculum aimed at providing students with a humanistic education? Based on this question, we established the central objective: to explore the conceptual and principled elements of providing students with a humanistic education in basic education, divided into the following stages: the first stage explores the social function of the school from the perspective of Paulo Freire; the second stage constructs a conceptual framework to systematize Freire's classification method and thus a proposal for an emancipatory critical curriculum. The theoretical framework is based on the teachings of Paulo Freire (2021), Ana Maria Saul (2019), Valter Giovedi (2019), Saul and Voltas (2021), Silva and Weide (2014), and Gil (2002). The research method adopts a qualitative approach and is guided by historical materialism. A systematic literature search was conducted within Freire's conceptual framework. It is concluded that curriculum must be understood as a political and social tool based on the principles of dialogue, creativity, curiosity and utopia. It is hoped that this study will shed light on the contribution of a critical humanistic and emancipatory education to the comprehensive development of students.

This work aims to reflect on the contributions of the Black Educator Movement (Movimento Negro Educador) to pedagogical practices and the school curriculum, especially in the context of basic education. It is based on the understanding that school curricula, historically marked by a Eurocentric perspective, tend to silence or marginalize the knowledge and experiences of the Black population. The research, qualitative in nature and with a theoretical approach, is grounded in the works of authors such as Nilma Lino Gomes (2017), Kabengele Munanga (2004), Eliane Cavalleiro (2001), Petronilha Beatriz Gonçalves e Silva (2003), and Beatriz Nascimento (1985), who discuss education on ethnic-racial relations, Black epistemologies, and quilombismo as a form of resistance and knowledge production. The legal framework adopted is Law 10.639/03, which amended the Brazilian Law of Guidelines and Bases (LDB) to include the teaching of Afro-Brazilian and African history and culture in the school curriculum. The effectiveness of this law depends on anti-racist pedagogical practices and the valorization of Black voices within educational spaces. The Black Educator Movement, a concept primarily developed by Nilma Lino Gomes, is understood as a set of actions, individuals, memories, and struggles that, throughout history, have challenged the Brazilian educational system and formulated strategies to confront structural racism.By recognizing this movement as a producer of pedagogical knowledge, this work seeks to highlight how its practices influence teacher education, curriculum organization, and the construction of a school that values diversity and combats racial inequalities. This study shows that the Black Educator Movement is a political, pedagogical, and epistemic force capable of transforming school practices and inspiring the development of an anti-racist, plural education committed to social justice. In this sense, the study contributes to strengthening the struggle for a school that not only includes Afro-Brazilian content, but also reconfigures itself based on Black epistemologies and attentive listening to those historically silenced by the hegemonic curriculum

This study investigates human rights education and anti-racist education. Although anti-racist education is provided for in legislation such as Law No. 10.639/2003, it still faces several challenges regarding its effective implementation in the school environment, especially in the early years of elementary education. Currently, there is a concerning gap between legal discourse and pedagogical practice, which is marked by the lack of adequate teacher training and social resistance to topics considered sensitive to be addressed in schools. In light of this scenario, the research question emerges: how can we expect the construction of an anti-racist society when the teaching of human rights and the implementation of anti-racist education in schools are systematically neglected? This concern, experienced in practice as a teacher, motivated this investigation into the obstacles faced by other educators when addressing these topics effectively. Therefore, the study has the following specific objectives: (i) to analyze, in light of Law No. 10.639/2003, the teaching of human rights and anti-racist education in the early years of elementary school; (ii) to examine the pedagogical practices adopted by teachers in addressing racial issues and the principles of human rights. The methodology used was qualitative, based on bibliographic review and document analysis, considering authors such as Freire, Candau, Munanga, and Mogilka. As a result, it is understood that a critical teacher education, aligned with school realities and diversity, is essential to transform the school into a space for combating racism and social inequalities.

This paper addresses the importance of literacy in the mother tongue in the early years of elementary school, highlighting its essential role in the formation of critical and conscious individuals. It is based on the premise that teaching and learning processes must be constantly studied and improved, especially in view of current challenges, such as expanding access to school and guaranteeing the right to learning. While literacy is related to the technical mastery of the alphabetic system, literacy involves the social use of written language, with meaning and context, enabling a critical reading of the world. This concept is aligned with the ideas of Freire (1989), who advocates literacy focused on awareness and social transformation. In view of contemporary social changes, it is urgent to redefine such practices, promoting more meaningful learning experiences, focused on the autonomy of students and their ability to critically interpret reality. The purpose of the study is precisely to reflect on how literacy in the mother tongue can contribute to the construction of students' reading of the world in the early years of basic education. To this end, the research adopts a qualitative and bibliographical approach, aligned with the state of the art, based on renowned authors such as Soares (2018), Ferreiro (2017), Freire (1987) and Kleiman (2005). Soares (2018) differentiates literacy from literacy and advocates pedagogical practices that integrate both processes. Ferreiro (2017) emphasizes the constructive nature of literacy, highlighting the different levels of understanding of the writing system. Freire (1987) proposes a critical literacy, based on dialogue and reflection. Kleiman (2005) contributes to the concept of literacy as a social and contextualized practice. The study argues that literacy and literacy should go hand in hand from the early school years, promoting the meaningful appropriation of written language and contributing to the development of students' critical awareness. Literacy, understood as the ability to use written language in different social contexts, is essential for the formation of readers of the world — individuals capable of interpreting, questioning and acting on reality. Thus, the work proposes pedagogical paths that integrate the learning of written language with citizenship formation, valuing the role of the school in the construction of a more just, critical and transformative education.

The training of teachers for Early Childhood Education in Brazil is an increasingly relevant field of study, given the fundamental importance of this stage of basic education for the integral development of children. This final undergraduate paper aims to analyze the contemporary challenges and perspectives surrounding both the initial and continuing education of teachers working with children aged zero to five. This study will address the historical transformations and legal frameworks that have shaped Early Childhood Education in Brazil, as well as discuss the current demands for constructing a high-quality, inclusive pedagogical practice aligned with 21st-century educational needs. The research, of a qualitative and exploratory nature, is based on bibliographic review and document analysis. In addition, the potential of continuing education, reflective practice, and the use of technologies as tools for professional development will be explored. It is expected that this study will contribute to the debate on the appreciation of teaching in Early Childhood Education and to the proposal of more effective training policies and practices that promote the full development of children and the construction of equitable and transformative education. The discussion will be deepened based on authors such as Perrenoud (2000), Imbernón (2009), Kishimoto (1999), and Cruz (2010), who offer important contributions on teacher education and early childhood education

This study analyzes the use of Brazilian national cinema as a didactic resource in Geography teaching, aiming to explore how short films can contribute to understanding the different ways of inhabiting Brazilian landscapes. The research, qualitative in nature, was carried out with 4th-grade elementary school students in a municipal school in the interior of Minas Gerais. The pedagogical approach included the screening of the short films Naiá and the Moon, Waters of Romanza, and The Things That Live in Things, followed by discussion circles and the production of drawings. The analysis of the graphic records, in light of Peircean semiotics, made it possible to identify conceptual, procedural, and attitudinal learning related to cultural diversity, the human-nature relationship, and the forms of organization of geographic space. The results indicate that national cinema, by integrating artistic language with curricular content, fosters the construction of more sensitive, critical, and reality-connected geographic knowledge

This study aims to analyze, from the perspective of neuroeducation, how recognizing individual learning styles and paces can contribute to the development of more personalized pedagogical practices grounded in neuroscientific evidence, with a focus on high school students. Through a literature review, the main foundations of neuroeducation related to the construction of knowledge are explored. Drawing on the contributions of authors such as António Damásio and Stanislas Dehaene, the discussion highlights how emotional factors and core brain functions—such as active engagement and consolidation—directly influence the learning process. The analysis reveals that while neuroscience does not provide ready-made answers or fixed models for education, it offers valuable insights for more effective teaching practices that are responsive to students' individual differences. The study also discusses the challenges teachers face in integrating neuroeducational knowledge into everyday school life, considering institutional constraints, gaps in teacher training, and the persistence of misconceptions about the brain, known as neuromyths. As a contribution, the research encourages critical reflection on the need to bridge science and educational practice, advocating for public policies that support ongoing teacher training and foster interdisciplinary dialogue between educators and researchers. By emphasizing the relevance of neuroeducation in promoting more humanized and inclusive teaching, this work contributes to expanding learning opportunities in high school and highlights the essential role of teachers in driving social transformation.

There is a growing concern that new generations are becoming increasingly less inclined toward scientific careers and more apathetic in school activities. Driven by this context, this study aims to shed light on the possibility of increasing students' interest in Physics through experimental activities. Based on the assumption that there is a lack of equipment in high school physics laboratories and that students are avid consumers of technology, this research proposes using 3D printing to produce instructional materials for physics laboratories while also captivating students through a manufacturing technology that is widely discussed but not well understood. To assess this possibility, a set of laboratory materials was designed and 3D-printed by the author and subsequently employed in a seven-week course with eight high school students at a private school in the state of São Paulo, Brazil. The activities covered Dynamics (determination of gravitational acceleration and acceleration in pulley systems) and Statics (conditions of equilibrium in systems with concurrent forces in different configurations). Students were responsible for assembling the equipment, making theoretical predictions, experimentally obtaining the expected quantities, and comparing the results while identifying possible sources of discrepancy. At the end of the course, semi-structured interviews were conducted with some students, which revealed both motivational and methodological impacts of 3D printing in Physics teaching: on the one hand, fostering curiosity in the technological field by demonstrating that the equipment was designed and manufactured within the school itself - thus highlighting the feasibility of 3D printing for educational and domestic use - and, on the other hand, enabling the implementation of experimental strategies in Physics through low-cost, teacher-designed materials that can also be shared across other areas of knowledge.

This study analyzed the impact of the installation of paddle aerators on the treatment efficiency of a facultative lagoon responsible for the depuration of effluent from the Savencia Brasil Industry (Angatuba/SP). The installation was carried out with the aim of improving the effectiveness of the wastewater treatment from this processed cheese industry through aeration. The industrial effluent treatment process helps reduce parameters such as turbidity, Chemical Oxygen Demand (COD), and Biochemical Oxygen Demand (BOD), in addition to stabilizing the pH and increasing the Dissolved Oxygen (DO), occurring progressively and naturally. The applied methodology included the installation of eight aerators and the monitoring of the efficiency of the oxygenation process. For this purpose, physicochemical analyses of the treated effluent were carried out to verify the effectiveness of the implemented system. Finally, the expected results involve improving the quality of the final effluent and minimizing the environmental impact caused by the industry, aiming for a more sustainable operation and improved well-being for the local community.

This thesis investigates, through theoretical-computational methods, the development and characterization of two multifunctional materials intended for catalytic and therapeutic applications. In the first part, silver alpha tungstate was evaluated as a functional material for the generation of reactive oxygen species. The optimization calculations of the lattice parameters and the construction of morphologies via the Wulff method evidenced the predominance of the (101) surface in the formation of a hexagonal bar, which, combined with the specific distribution of oxygen vacancies and the configuration of silver quantum clusters, showed a high capacity for the selective adsorption of H₂O and O₂ molecules. These interactions promote the formation of reactive precursors, essential for oxidation processes and photocatalytic applications, confirming the relevance of silver alpha tungstate as a catalyst in environmental processes and in the degradation of pollutants. In the second part, the thesis addresses the application of boron nitride nanotubes as a nanocarrier for the drug FLU, an antiandrogen used in the treatment of prostate cancer. Through DFT calculations, it was observed that the encapsulation of FLU in BNNT does not promote significant structural changes, maintaining the stability of the system both in vacuum and in aqueous media. The results reveal favorable interactions, characterized by negative adsorption energies, which indicate a charge transfer from BNNT to FLU, facilitating the formation of a stable complex. Molecular dynamics simulations corroborated the maintenance of the encapsulated drug over 50 ns, with analyses of center of mass distance, RMSD and radial distribution functions confirming the structural integrity of the system. In addition, the analysis of the binding free energy by MM and PBSA showed that van der Waals and electrostatic interactions are determinants for the stability of the FLU complex with BNNT. Together, the results demonstrate the potential of the studied materials both in promoting catalytic reactions and in improving drug delivery, opening new perspectives for the development of innovative multifunctional systems in environmental and therapeutic catalysis.

Approximately 700,000 tons of industrial dyes are released into the environment annually, many of which are toxic and genotoxic, requiring advanced treatments. Advanced Oxidative Processes (AOPs) emerge as an alternative for efficient manipulation by reactive oxygen species; these processes can be optimized by specific oxides such as TiO2. Thus, the main objective of this study was to analyze the efficiency of the manipulation of the dye Erythrosine B, with the application of AOPs, photolysis and photocatalysis with the addition of titanium dioxide, and to verify the effects related to the modification of some parameters, namely pH, type of catalyst (different crystal structures) and concentration of catalyst. The results showed that Erythrosine B presents satisfactory manipulation (maximum absorption at 526.5 nm) during photolysis and photocatalysis, presenting manipulation efficiency of 39.8% after 5h of photolysis and 48.3% after the period of 2h and 15 minutes in photocatalysis. The optimized settings were: TiO2 (P25 – 80%/20% anatase/rutile); TiO2 concentration 1.0 g/L and medium pH equal to 7.0. In the optimized scenario, the kinetic constant was 1.51×10−3 min−1 for photolysis and 4.91×10−3 min−1 in photocatalysis.

With the technological advancements and industrial innovations of the 20th century, much of the mechanical work began to be performed by electric machines, primarily induction motors, due to their practicality and robustness. As a result, the control of these machines became a fundamental component in the application of this technology, given the wide range of applications that require specific behaviors from these motors. In this context, the project to be developed involves the practical application of a drive and control bench for a squirrel-cage three-phase induction motor. The bench will consist of the induction motor, a frequency inverter, encoder, signal conditioning circuits, DC power supply, and microcontroller. The implementation of this project covers theoretical aspects related to the induction machine, microcontrollers, power electronics, drive circuits, and sensing systems. Experimental results aim to demonstrate the operation of the bench, enabling future use for analysis and control of three-phase electric machines in the laboratory. Ultimately, the work aims to contribute to the educational environment and the understanding of concepts taught in various disciplines of the Electrical Engineering course at the Federal University of São Carlos

The limit to the right to private property is a too much discussed question in Locke’s thought. It is possible to state that this theme divided Locke's interpreters into two main groups: those who believe Locke defended the unlimited right to private property and those who, on the other hand, tried to show that Locke defended the limited right to private property. This work aims to demonstrate that the right to private property for Locke is only established when limited to conditions of a moral and political-legal nature, examining these conditions both in the state of nature and in the political state. To this end, we intend to highlight the restrictions suggested by Locke himself to the right to private property: restriction against waste, and to leave enough and as good for others and the natural human incapacity to appropriate considerable amount of land so as to not to leave enough and as good for others, in the context of initial state of nature, in which there is much more land available than individuals to appropriate it. With the invention of money and the emergence of the State, these conditions change. On the one hand, with the introduction of money, restrictions are reconfigured, as utility changes and appropriation capacity expands. On the other hand, the territorial delimitation inherent in the constitution of the State now restricts the amount of land available, which changes the requirement to leave so much land available and of such good quality that “enough” is left for the conservation of each of the others. Thus, based on the articulation between the foundations of the right to private property and its restrictions, and the role of money and the political State within the scope of these relations, we intend to offer more evidence and corroborate the thesis that for Locke the right to private property is only established when circumscribed by conditions of a clearly limiting nature to this right.
