From a research about the potential of the Sorocaba river, in its urban extension, it can be observed that the river, in different stretches, can be used for leisure and tourism practices. In this work, I dedicated myself to detecting the tourist potential of this Sorocaba identity, a beacon of waiting for a refreshing time and part of the implementation of a tourism plan that values local socio-environmental, cultural and economic aspects. Here, an unprecedented survey will be made in terms of structuring the Sorocaba river as a navigable river, aiming to flow actions in the municipality of Sorocaba. Being a destination, with indentitary attractions for the State of São Paulo, requires a new way of seeing the composition of the urban landscape. The Sorocaba river incorporates different elements that allow, for future scenarios, the development of Sorocaba. It is part of the history of the development of the city and region's mobilities between highways, railways and population transformations. The Sorocaba river, which gave origin to the city's name, is born in the São Francisco mountain range and consists of small streams that integrate the Tietê river basin and flow into the reservoir (CAMPOS, 2018). In the old days there was more forest in Sorocaba than nowadays; in the virgin forest lived animals and a lot of birds. The Sorocaba river is our identity and inspires several ways of structuring a city with tourist potentialities, which are building a discernment while the possibilities of the city of Sorocaba.

The present thesis defends that freedom (Freiheit) in the philosophical thought of G. W. F. Hegel (1770-1831), as presented in the “third part” of Philosophy of Law (1821), only concretizes in the State (Staat). Although he recognizes that particularity is a mark of the superiority of the modern world in relation to the ancient world, Hegel is aware of the risks of its reduction to property (Eigentum). In the Philosophy of Law, this reduction to needs (Bedürfnisse), corresponds to the moment of bourgeois civil society (bürgerliche Gesellschaft), characterized as “loss” (Verlust) of family ethics (Familie), which, as moments of Ethics (Sittlichkeit), are suppressed (aufheben) by the State. Thus, although he recognizes that freedom in the modern world, also presupposes the right to property and the satisfaction of particular needs, Hegel, in the “third part” of the Philosophy of Law, the ethical organicity of youth writings and understands that only through institutional mediation (Vermittlung) that has its consummation in the State, individual freedom is realized. Thus, it concludes that only the State, as an effective reality (Wirklichkeit), is able to recognize the particular will and elevate it to universality, by enabling the individual to have concrete freedom and, in this way, an ethical life (Leben sittliches) realized.

This research analyzes two films by Belgian filmmaker Chantal Akerman, Saute ma Ville (1968) and Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles (1975), with the purpose of investigate the domestic claustrophobia sensation as an authorial trait of Akerman, an element that is referenced all over the filmograpy of the filmmaker. Therefore it is important to highlight the thematic and stylist crossings in the directress’s work. We emphasize along the analysis the montage, the sound use, the performance, the framework and duration of the plan as ways to build a cinema based on sensations. The Akerman’s formal and thematic choices are associate with the questions purpose by modern cinema, in the same time, weembracing the present affinities in her work with the feminist theory. Akerman combines elementes of referentiality to build her own cinema, an authorial cinema, which creates visibilities and fissure that produces sensitive forms of apprehension, and therefore, others critical possibilities to the women’s everyday, the domestic claustrophobia experienced in their daily lives.

Serious environmental issues have been caused by the massive consumption of plastic products. One of many strategies to reduce the environmental impacts is the development of bio-based and biodegradable polymeric materials. In general, biodegradable polymers have limited production capacity and, consequently, higher costs. Lignin, on the other hand, is abundant in vegetable tissues and is obtained majorly as by-product of the paper industry. Consequently, it exhibits renewability, high availability and low cost. The incorporation of lignin in the biodegradable polymer poly(butylene succinate-co-adipate) (PBSA) can provide more competitive costs and functional properties to it, like UV radiation protection. In this work, PBSA-based films were extruded with lignin nominal concentrations from 0 to 15 wt.%, with different processing parameters. The influence of composition and extrusion conditions (temperature and screw rotation) were assessed by structural, thermal, rheological, morphological and mechanical analysis. The results showed that lignin dispersion is strongly influenced by the processing conditions. Phase compatibility was observed and, also, evidences of possible partial miscibility between lignin and PBSA were found. However, the presence of lignin catalyzed the hydrolytic degradation of PBSA during the extrusion processes due to lignin’s acid character. Additionally, experimental results clarified, to a certain extent, the dualistic particle-macromolecular behavior of lignin, which seem to vary with the conditions of extrusion and analysis. Lignin restricted the molecular mobility of PBSA when the samples were in the solid state and during their crystallization, but caused a lubricating effect when the system was submitted to shear strain in the melt state. The extent of these effects was shown to depend on lignin dispersion levels and, consequently, on the processing parameters.

Esta tesis tiene el objetivo general de comprender cómo los cambios políticos y sociales derivados de la construcción del Estado Plurinacional de Bolivia repercutieron en la educación regular del sistema educativo boliviano. Considerando la temática, todo el proceso de construcción del conocimiento se ha convertido en una amplia investigación de campo, debido a que la mayor parte de la bibliografía es extranjera – lo que exigió una búsqueda in loco de las fuentes –, así como por la necesaria presencia física para proceder con el conjunto de las entrevistas y observaciones en diferentes unidades educativas de la ciudad de La Paz, altiplano boliviano. Para un acercamiento más ajustado al objeto, primero se trató de los elementos histórico-organizativos de la sociedad boliviana, entrelazados con la historia de la educación en Bolivia, en un recorrido que parte del período preinca, pasa por la invasión europea y Colonia, llega a la República y avanza en la consolidación del Estado Plurinacional, lo que coincide con el marco temporal específico de esta tesis. A continuación, trayendo datos de las observaciones y las voces de los maestros entrevistados, pasamos al propio modelo educativo, caminando en sus fundamentos, sus características, su trayectoria formativa y, finalmente, su proceso de gestión. La perspectiva inicial fue que, en la construcción de un modelo educativo cuyo lastre corresponde al producto de las luchas del estrato históricamente subalternado que ascendió a la dirección del Estado, la educación podría, dialécticamente, colaborar en la conformación de un nuevo consenso, guiado por una sociabilidad superior. Como resultado, se percibe que el cambio en los fundamentos del Estado y del Sistema Educativo ha provocado mejoras en la estructura del modelo, en la cobertura educativa, en las condiciones de permanencia, en el proceso educativo y en los resultados de este proceso, y que los maestros apoyan y reconocen este cambio. Sin embargo, la implementación aún reciente resalta, a nivel escolar, las propias contradicciones de la sociedad boliviana, en el afán de afirmar estándares previos, ajustados a otros fundamentos, incluso incompatibles con los del Sistema Educativo Plurinacional. Así, la maduración del modelo sería necesaria para un abordaje más acertado, pero el golpe de Estado llevado a cabo en 2019 deja incierto si habrá tiempo para el ajuste de esta brecha.

The structural changes in the world economy and the current technological advances have fostered a new business model operated through digital platforms, giving rise to new forms of work organization in which data extraction and processing become new sources of raw material, giving shape and meaning to what many authors have been calling platform capitalism. This research aims to contribute to the understanding of this context, by exploring the potential impacts of this business model. While considering a complementary concept, that of a connectionist capitalism, the focus is on two of its main attributes: professional insertion via networks and flexible work. This research sought to explore the emerging theme of platform capitalism and its impacts on the work organization of drivers who use transport passenger applications in Brazil and Chile. To do this, the research employed both a theoretical approach through a systematic bibliographic review and narrative bibliographic research, as well as an empirical approach, (i) through a survey of 54 Brazilian drivers and 56 Chilean drivers, (ii) semi-structured interviews with 30 Brazilian drivers and 17 Chilean drivers; (iii) observant participation in 13 Facebook groups and two WhatsApp groups, one of them with 144 participants and the other with one 48. Among the results found it is highlighted that: (i) the bibliographic review of the literature on the subject provided the scope for systematization of the researched studies around three main axes: new work practices, job insecurity, and labor legislation, (ii) the empirical research revealed that despite the driver’s perceptions (from both countries) of exploitation, excessive poorly paid work hours, and high job insecurity. Yet, the flexibility is considered the great advantage of this process of professional insertion in a context of unemployment and increasingly precarious work.

This research aimed to identify what are the components of the technological capabilities and the teemed innovation dimensions presented in technological-based companies (TBC). Precisely, it was investigated how the TBC develops the technological capabilities to generate innovation, due to the pressure to adapt themselves to the continuous technological changes. In doing so, qualitative research was developed and the method selected was multiple case studies. The techniques adopted were semi-structured interviews with TBC top management, direct and non-participative observation, and document analysis. The results showed that in small TBC, research and development (R&D) tends to be carried out with other external partners, including 'intermediaries' or informally, as the company does not have enough capacity to internalize the entire R&D process. Besides, in the innovation processes used by managers to develop R&D, experimentation, imitation, and the inclusion of 'adoption' stand out. The five theoretical dimensions of innovation (product, process, behavioral, market, and strategy), were manifested in the studied TBC, and the most evoked by the leaders was the 'innovation in strategy', because as companies grow, they become more complex and sophisticated, requiring a more transparent and more effective corporate strategy. The technological capacity, initially represented by four components (human capital, physical capital, organizational capital and products, and services) was also identified in the interviewees' speech, and human capital was presented as the most remembered by them, due to the recognition of that employees can drive the organization to success. Finally, the theoretical and empirical research model was consolidated, with the integration of a new component of technological capacity, called 'cultural capital', which facilitates the development of innovative processes. It is believed that this thesis may provide meaningful contributions to studies on TBC, helping to identify the theoretical and empirical links that bring innovation and technological capacity together, aiming at adapting them to continuous technological changes.

Soybean [Glycine max (L.) Merrill] is one of the most important raw materials in the national and international scenarios due to its chemical composition, economic importance and diversity of application in the food market. The composition of soybeans can present significant differences depending on the variety used, the agricultural management, the place of cultivation and the edaphoclimatic conditions. In this sense, the objective of this work was to evaluate the physical, physical-chemical and technological characteristics of different soybean varieties cultivated in the southwest of the State of São Paulo. The experimental part was divided into three stages. The first consisted of characterizing four varieties of commercial soybean (SA, SB, RA and RB) regarding some physical and physical-chemical parameters usually applied in grain quality control. In the second stage, the soybean’s flour cultivars was obtained and these were evaluated for certain physical-chemical and technological parameters. Finally, in the third stage, the oils extracted from the different varieties were evaluated for the specific extinction and free acidity. With this work it was possible to identify the similarities and differences in relation to the chemical constituents and the physical characteristics of these soybean varieties. The varieties of high agronomic efficiency (SA and SB) stood out in terms of physical parameters, and the SB variety also had higher protein content (40%), which together with the lipid content presents the main physical-chemical parameters. As for technological characteristics, the traditional SB variety, once again, stood out from the others in relation to the water absorption capacity (2.85 g water / g sample). In contrast, the RA refuge variety stood out in terms of emulsifying capacity (61.44%). Regarding the quality of the oils obtained, the oil extracted from the SB variety showed greater free acidity and specific extinction. It was possible to conclude that the soybean varieties, both those used as a refuge strategy and those of high productivity differed in relation to their chemical, physical and technological characteristics. Thus, the results obtained in this work can assist in decision making regarding the choice of certain varieties for a specific application in the food industry

Nature conservation has been shown to be extremely important for the quality of life of the population with the maintenance of ecosystem services. There is pressure on public authorities to create, maintain, improve and increase actions in favor of the environment. A point that has been discussed is about these actions adapting to local peculiarities, making conservation of environmental resources increasingly viable, since Brazil has great heterogeneity in the characteristics and distribution of these resources throughout its territory. The decentralization of public environmental management transfers responsibilities from the Union to the states and from the states to the municipalities, in an attempt to achieve local environmental governance and strengthen social participation. The model of cooperative federalism in the country allows decentralization to occur without excluding cooperation between federal entities. The present study aimed to investigate the process of decentralization of environmental attributions and the fragmentation of environmental performance in different agencies and institutions within the public environmental management system in the city of Ribeirão Preto / SP. This study carried out a bibliographic and documentary survey and semi-structured interviews with the representatives of each environmental agency with a physical unit in the city of Ribeirão Preto, which were transcribed, and analyzed based on content analysis with the aid of the software. From the results obtained, it is possible to infer that decentralization in the city of Ribeirão Preto has its process supported by laws and has an institutional apparatus that makes it possible to achieve the objectives of this transfer of authority. The fragmentation was seen by the interviewees as a positive aspect when related to the specialization of the areas as a result of this process, however, efficiency in communication and interinstitutional cooperation is essential for public policies to function correctly. As one of the main points cited by the interviewees as a positive aspect, the proximity of the local government and the environmental agencies of the population enables social participation and provides easier access to the organs. On the other hand, this proximity to decision-making agencies in public environmental management can have negative consequences such as clientelistic practices that influence public authorities in order to seek private interests. Therefore, decentralization does not present itself as a problem, however, opportunistic actions by actors and sectors that take advantage of this process of transferring responsibilities to the local government generate negative consequences for sustainable development and collective interest, which may compromise the entire governance process. local environmental policy. Politicians with an active mandate have the power to influence environmental agencies, weakening them with the intention of hindering institutional actions or marginalizing the environmental issue. The lack of technical and financial resources at the municipal level compromises environmental defense and the local environmental governance process. These are major problems to be faced. In this way, environmental education must be worked on in search of changes in posture, mainly of the public power. The improvement of environmental decentralization is a great challenge and a permanent need in search of sustainability.

Between 2000 and 2012, 177 thousand indemnities were paid for the death of motorcyclists and 781 thousand for permanent disability in Brazil. These figures show that studies in this field are necessary in order to understand the general situation and mitigate the damages of the use of this means of transportation that continues to grow in Brazil. This study, regarding the national scenario, used morbidity and mortality numbers provided by the Ministry of Health through a database called DATASUS, population data from the IBGE (Brazilian Institute of Geography and Statistics) and fleet data provided by DENATRAN (Traffic National Department). With this data, the desired indexes were calculated to each region and state in Brazil. To get to other countries indexes, data from WHO reports were used, to show the mortality of motorcyclists in traffic accidents in those countries. It was noticeable the significant increase of the mortality of motorcyclists in Brazil, during the analyzed period, just presenting an apparent stability from 2012. It was also noted that the Northeast region is a problematic one in this respect, presenting the highest rates both in relation to the population and in relation to the fleet for the last year analyzed (2016). The Southeast region had the lowest rates not only in 2016, but throughout the analyzed period. When comparing the Brazilian indexes to the indexes of other economic similar countries (between 2006 and 2016), it was clear that the Brazilian ones are usually higher, when these other countries were the ones that had reached a high income level in the established period. It was also observed a tendency for the motorcycle to be more present in the country's fleet when it has a lower income.

The sludge generated in Water Treatment Plants (WTP) has a high moisture content, normally greater than 95%, and is considered to be solid waste according to Law 12,305/2010, which foresees non-generation and reduction of solid waste as priorities, closely followed by reuse and recycling. The volume reduction of WTP sludge can be carried out through dewatering, a process consisting of the removal of free water, which is supernatant and can be found in the interstices of solids, using natural or mechanical systems. Among the natural dewatering systems, Draining Beds (DB) have shown promise, however, the process needs to be further researched. Thus, the main objective of this research was to study the influence of multiple factors, such as sludge solids content, sludge layer height, solids application rate (SAR) and different types of geotextiles, during the free water drainage stage of the dewatering process using DB. For this purpose, a Draining Bed system was built at bench scale, with a total of 335 drainage simulations being carried out, using 6 different types of geotextiles; 6 raw sludge total solids (TS) contents and 5 sludge layer heights. The analysis of the results allowed us to conclude that the stabilization of a pre-filter formed by the sedimentation of solids present in the sludge has an overriding role in the drainage process compared to the role of the different types of geotextiles. It was also concluded that the TS content of the raw sludge has an indirect relationship with the final percentage of drained liquid; the beds with higher SAR had higher percentages of good quality drained liquid and registered longer times until the end of free water flow; the drainage in beds with small sludge layer height and low levels of TS is not very efficient in promoting good quality drained liquids; the filter opening in the geotextile fabric is related to the promotion of drained liquids with high apparent color rates; and the characterization of the different types of sludges, mainly regarding particle size distribution and composition, can influence the drainage process.

Based on the interest in Brazilian Early Childhood Education, an attempt was made to unveil its historical construction process in the country between 1982 and 2008. For this purpose, the Revista Criança, periodical with a great repercussion among educators in this time period, produced by the Ministry of Education, was used as a reference and object of research. Thus, in order to accomplish the goal of understanding how Early Childhood Education was constituted in the country based in the selected object, 46 issues of the Revista Criança were analyzed. The study focused on the ‘Articles’ section, based on three analysis categories: child conception; teacher's role; and the function of Early Childhood Education. Furthermore, the material was periodized into four periods. The periods are not dissociated, and although in each of them certain ideas stand out at the expense of others, it is noted that the same ideas are reframed and remodeled in other periods. Thus, each period was assigned with a title which summarizes the highlighted ideas at that time, namely: 1st The monitor and the practical guidelines for health, care and education; 2nd The Federal Constitution and the search for pedagogical intentionality; 3rd The child as a person with rights and teacher education; and 4th Child protagonism and the search for innovative practices. Based on two main conceptual tools: the grammar of schooling (TYACK; CUBAN, 1995) and the discourse on practice (DEPAEPE, 2005; HAI, SIMON, DEPAEPE, 2015; 2016), it was concluded that both, the constructed journal’s practical discourse, as well as the grammatical constituent points of Early Childhood Education, revealed certain continuities in all periods of the Revista Criança, in a constant process of reframing ideas, practices and conceptions. Such results led to the Thesis ‘construction that Brazilian Early Childhood Education has always been, and still remains, in search of its definition, and in this process there are more permanencies than great ruptures. In this sense, the Revista Criança represents a locus for understanding the complex historical and cultural relations waged in Early Childhood Education in the country. Therefore, it is expected that this Thesis will contribute to the understanding of Brazilian Early Childhood Education, besides to supporting new paths and possibilities in the face of the challenges found in these spaces.

The use of biomass in order to obtain chemicals and fuels that can substitute the fossil matrix has been investigated and treated with high interest. This way, the research in catalysis becomes essential to overpass barriers and to consolidate the use of such renewable sources. Tin silicas have been showed as a promisor candidates in glucose to fructose isomerization, given the fact the last hexose is very interesting regarding its conversion to HMF, a platform molecule with a high potential to substitute monomers obtained from fossil fuels. Therefore, this work has as objective to synthesize water-resistant catalysts, with Lewis acidity properties, high concentration of silanol groups and a high pore diameter, as a way of surpassing the limitations imposed by the Sn-Beta zeolite, which is the most studied catalyst for the isomerization reaction. This way, the effect of the synthesis parameters on Sn-MCM-41 and Sn-SBA-15 will be investigated. Furthermore, we seek to understand, by synthetizing Sn-MCM-48 and Sn-SBA-16, how the change in the mesoporous’ structures (M41S and SBA) influences the catalysts’ properties, in a way that the main goal is to suit the catalytic properties with the structural and textural properties. Increasing the acid concentration and the Sn loading led to a bimodal distribution of the unit cell parameter for the Sn-SBA-15, while for the Sn-MCM-48, the increase in the last parameter to 4,5% prevented the ordered formation of such material. Thus, the best synthesis parameters for the formation of a well-organized structure were 3,0% Sn for both Sn-SBA-15 and Sn-MCM-48 materials, and 0,049 mol L-1 for Sn-SBA-15. It was observed a good structural ordainment for the Sn-MCM-41 materials synthetized with NH4OH, while the same was not observed for the ones synthetized with TMAOH. The superficial area and the microporosity formation were not significantly affected by the synthesis parameters among the materials, but they were actually affected by the different scaffolds studied. A study regarding the catalytic activity of Sn-SBA-15 showed that the reaction depended on the identity of the solvent used, in a way that the initial TOF for fructose formation increased in the following order: methanol

16 sensing points for the construction of an array of biosensors. The components of this device have been individually evaluated and their construction design has been optimized for the best performance of the sensors. Once the good performance of µPBDMA was proven, the construction of the biosensor was then carried out to determine D-(+)-Glucose. Using the cyclic voltammetry technique for a D-(+)-Glucose Glucose solution, the highest peak currents obtained were for films containing carbon black CB, thus selecting this carbon nanomaterial in the manufacture of the biosensor. The analytical curve obtained showed a linear response range for D-(+)-Glucose concentrations from 0.1 to 40 mmol L-1, and a detection limit of 0.03 mmol L-1, showing the success of the proposed architecture of the built biosensor, being later used for the consolidation of the project proposal which is the analysis multiplexing using the µPBDMA. As an alternative to the enzymatic method for the determination of creatinine, a sensor was developed based on the complexation of the Fe3 + ion with the analyte, thus indirectly determining the concentration of creatinine in the sample by differential pulse voltammetry, monitoring the reduction of free Fe3 + (not complexed) to Fe2 +. This architecture was successfully applied on two platforms, using a low volume device (3 µL), obtaining a linear working range for creatinine (CNN) from 0.1 to 6.5 mmol L-1, with a limit detection of 0.043 mmol L-11. In µPBDMA, studies were performed sequentially with D-(+)-Glucose, creatinine and uric acid, obtaining linear ranges from 0.625 to 20 mmol L-1 for D-(+)-Glucose, from 0.106 to 4.500 mmol L-1 for creatinine and 0.047 to 3.000 mmol L-1 for uric acid, with detection limits of 0.12, 0.084 and 0.012 mmol L-1 for D-(+)-Glucose, creatinine and uric acid, respectively. Repeatability studies of the proposed system were carried out, with RSDs of less than 6.25% being obtained. Studies on the influence of potential interferents were also investigated, with the RDSs being less than 8.25%. In addition, the performance of µPBDMA was assessed using urine samples, obtaining recoveries between 97.4 and 104% for all biomarkers. A microfluidic device coupled to an immunosensor was also developed to detect high levels of PSA. For the use of this system, it was adapted to a Spinner, a toy that has a central bearing to rotate it around its axis. For this, a base with a rod was used and fixed to the Spinner bearing to use it as a centrifuge. This system was developed to load the solutions from the injection point to the disposal point and to separate the blood serum and red blood cells in capillary tubes. The results obtained for the determination of PSA by the immunosensor proved to be promising, given the good linear range obtained (0.5 to 25.0 ng mL-1), and also the detection limit (0.0014 ng mL-1) . The performance of the immunosensor was verified for synthetic human serum fortified with three different concentrations of PSA, obtaining good recoveries of the analyte.

Urban walkability, an insurgent topic in contemporaneity, brings us new perspectives for the qualitative improvement of the urban environment in relation to the human scale. Since the exacerbated growth of cities in the 20th century and the phenomenon of urban sprawl, the predominance of motorised transport as the main means of displacement, we have observed the unfair overlapping of pedestrian space by that modal and the consequent devaluation of public space. Theoretical debates on the subject, especially since the 1960s, have gradually promoted rethinking about cities, and the contemporary way of life in the social, economic and environmental sphere. In this multifaceted context, walkability stands out as a qualitative value because it is able to establish connections with the public space and develop the relationship of belonging with the city environment. In this way, this investigation was based on a dialectical analysis between concepts, theories and practical experiences of plans and projects as a way to identify the guidelines and the essential elements of design for the valuation of urban walkability. As a practical experience, the city of Zaragoza (Spain) has in recent years presented a development process in its plans, projects and urban requalifications, which culminated in new perspectives and spatial concreteness for walking with the Pedestrian Network. As a result, it was possible to synthesize the guidelines for the formation of the Pedestrian Network and the design elements for assessing walkability. In view of the complexity that urban walking encompasses, this study shows that the concept of the Pedestrian Network is the main way of valuing walking in the urban space, as this is the most egalitarian way of moving and experiencing our cities.

The main aim of this work is to establish the well posedness for a dispersive partial differential equations systems and for a partial differential equation, with initial data belonging to Gevrey space. The proof relies on estimates in norms adapted to the linear part of the equations. In particular, estimates in Bourgain spaces are proven for the linear and nonlinear terms of the system and the main result is obtained by a contraction principle. The class of system in view contains a number of systems arising in the modeling of waves in fluids, stability and instability of solitary waves and models for wave propagation in physical systems where both nonlinear and dispersive effects are important. The techniques presented in this work were based in Grujić and Kalisch, see [21], who studied the well posedness of a IVP associated to a general equation, whose the initial data belongs to Gevrey spaces.

Productive backyards are multifunctional spaces that are very present in the context of family farming. These spaces present in the productions of the farming families their cultural characteristics, through specific techniques and also regional plants capable of guaranteeing the food security of the families. The present work was elaborated from a case study with the objective of verifying what is produced in the productive backyards in the Zumbi dos Palmares settlement in the municipality of Mari, in the state of Paraíba, analyzing its diversity and its contribution to food security and income of farming families. The methodology used was qualitative and quantitative and the instruments used were semi-structured interviews, as well as informal conversations in 41 batches of family farmers who had productive yards in the settlement. There was also a tour for a better observation of the productions as well as for the photographic records. In the results, we found 13 animal species, from seven different families and 87 plant species, with 45 different families, among fruit, medicinal and tuber species, totaling 100 species in general. We conclude that the productive backyards of the Zumbi dos Palmares settlement show that, even with the relatively low number of species, animals and vegetables, but with the presence of several fruit and food species in the region, families maintain local food security and improve the composition family income with the sale of surpluses.

The water crisis has been highlighted on the international scene. Although the water available on the planet is sufficient to meet the demands, its poor distribution compromises the supply in various regions of the world and at specific times of the year. Several communities have been developing tools to estimate the potential impacts of water use by man, and a tool that is gaining prominence is the water footprint. Proposed by two communities, the Water Footprint Network (WFN) and the Life Cycle Assessment (LCA) standardized by ISO 14046: 2017, the tool measures the appropriation of water resources by man and their impacts. Thus, this research aims to compare the two water footprint approaches and the application of the two methodologies in a Federal Institution of Higher Education (IFES) located in the Sorocaba River Basin, as a support for decision making. Although the two methodologies present consistent subsidies, the WFN focuses on the volume of water consumed, it is more efficient in raising awareness about the amount of water appropriate for man and less complex for application, however there are uncertainties regarding the calculation of the gray water footprint, because it does not assess the potential impact of the pollutant, but the amount of water needed for its dilution in the basin. ISO 14046: 2017 is more efficient in demonstrating the potential impacts and risks related to the use of water resources, but it is complex and requires greater efforts for application. The norm does not define the method leaving the subjective choice. In addition, the methodology does not include the use of green water. For the application on campus, the available data was sufficient to carry out the assessment of water scarcity from direct water use. In the application of the methodologies, the unsustainability of the basin was identified between the months of May and November in both methods, however, the LCA approach showed greater sensitivity in the result, presenting water scarcity in the annual basis, which did not occur in the WFN.

This research has as general objective to identify and understand the declared practices of polyvalent teachers and managers about the teaching of mathematics in a municipal public school in the city of Rio Claro in the interior of the state of São Paulo, which presents high rates in external evaluations. The theoretical analysis of this work was based on the related themes on the theme and in Tardif (2014) and Gauthier (2013) on teaching knowledge, in Shulman apud Mizukami (2004) on knowledge base and in Serrazina (1999), Pais (2013) and Nacarato; Mengali; Passos (2017) on Mathematics Education in the early years. A survey of the main legal documents related to the topic was carried out. Methodologically, the study was based on the qualitative interpretative approach. The research had the voluntary participation of twelve teachers and two managers of the selected school. For this, we used as a data collection instrument mixed questionnaires and semi-structured interviews. For data analysis, we used the data triangulation technique with the intersection of information and built the following categories: continuing education in mathematics, external evaluation, development of mathematics teaching challenges and possibilities in mathematics teaching, teacher training development. As a result of the triangulation of the interview data from the questionnaires, documents and theoretical contributions, we verified the declared practices of teachers and managers presented the following indications: development of simulations, training practices involving chess, development of reading practice for the resolution of problems at the Brazil Math Test, lower teacher turnover, knowledge sharing, development of school planning based on the data acquired at Brazil Tasting, with the development of logical reasoning activities and challenges, teaching materials available within the school environment. All of these indications may have contributed to the development of mathematics education and the results of the educational unit in the Basic Education Assessment System (SAEB). We also observed in these manifestations some challenges pointed out by teachers and managers, such as the lack of mastery of the content to be taught, the absence of courses focused on the area of mathematics, lack of knowledge to deal with the target audience of Specialized Educational Assistance (AEE) and the lack of space for sharing the knowledge of the experience. The results indicate the need for a continuous training policy focused on the area of mathematics for teachers and managers in the municipal network.
