    Global and local environmental changes are almost always associated with the increase of human activities, whose impacts cause significant transformations of the environment. These changes are linked to several socioeconomic and socioenvironmental factors, such as population density, urban expansion, agricultural expansion, deforestation, industrialization and the increasing production of solid waste, compromising the availability of natural resources and the quality of the environment. In view of these considerations, this work had the objective of elaborating an environmental diagnosis, in the face of erosive processes, through the use of the Geographic Information System (GIS) associated with soil loss prediction models, analyzing the dynamics of land use and land cover Over the years, and integrating the various physical and environmental factors to determine the degree of susceptibility of the environment through environmental fragility. For this purpose, an area characterized by intense erosion processes was selected, comprising the municipalities of São Pedro and Santa Maria da Serra, which has a direct contribution to the sediment load in the Barra Bonita Reservoir. In addition, such an area is part of the Corumbataí APA, that by law the preservation and conservation of its landscape should be ensured. The results showed that the area has suffered from the problem of erosion for more than 60 years and little has been done to reverse this situation. The year of 2015 was the one that presented the greatest loss of soil, and the expansion of the urban spot and agricultural areas caused a high fragility of the study area. This scenario demonstrates that the role of APA is not being addressed since its purpose is to balance local socioeconomic development with the sustainability of environmental resources. This study allowed the delimitation of areas restricted to anthropic interventions, which require greater care, and areas with greater aptitude for urbanization, contributing to the study of urban and environmental planning.

    Modified and acceptance control charts allow a new approach to statistical process monitoring. This research topic is little explored in the academic world, thus, this thesis contributes to the advancement of statistical process monitoring methods, both in theory and practice. Some decisions about the quality of processes and products are based on a set of economic and practical factors that involve their context, not just a probability, p-value. Statistical significance considers the theoretical decision probability of the statistical hypothesis test, and does not take into account trade-offs when choosing a decision alternative. In this work, when studying the X-bar R/S graphs, the hypothesis is that the limits of statistical control can be determined considering practical aspects. The model proposed in this thesis will be based on the acceptance graphs and on the capacitance indices, Cp and Cpk. The use of these indices is justified because they are widely used by the manufacturing industry, and these represent the practical aspect in the decisions about processes and products. The performance of control charts was evaluated via ARL (Average Run Length). An ARL model was developed when parameters are unknown, including the capability indexes. The results indicated that the proposed graph performs better than Shewhart's traditional charts. An implementation method was proposed and an illustrative case was carried out. In the illustrative example, the proposed method provided a smaller type I error, making it possible to improve the quality level in the process result.

    Currently, there is a need to increase the research aimed at the recovery of agro-industrial and forest residues worldwide. The food industry has produced an enormous amount of waste globally, among them the citrus waste that has a high potential to added value compounds, such as soluble sugars, cellulose and hemicellulose, pectin, d-limonene, ethanol and flavonoids. In this context, the aim of this project is to develop green methodologies applied to the extraction and analysis of natural bioactive compounds, such as flavonoids from orange waste derived of conventional and organic farming process. The sample preparation was carried out based on green techniques (microwave assisted extraction, ultrasound, conventional extraction with homogenizer aid), and a quantitative and qualitative determination through chromatography‘s techniques coupled to UV-Vis detector. In order to understand the behavior of the bioactive compounds of this matrix, four flavonoids (hesperidin, naringenin, hesperetin and nobiletin) were studied. The results showed that these compounds have a similar behavior to the variables tested, such as solvent extractor, temperature, time, among others, however they present differences when those are applied together in the different methods.

    Water and sodium intake are fundamental behaviors for body fluid homeostasis. These behaviors are controlled by a neural circuitry involving facilitatory and inhibitory mechanisms, which are modulated by signals activated by changes in body fluid volume and composition. Important inhibitory mechanisms for water intake and particularly for sodium intake are located in the lateral parabrachial nucleus (LPBN), a pontine structure. It is known that LPBN inhibitory mechanisms are controlled by several neurotransmitters, some increasing, others reducing the action of this nucleus on sodium intake...

    The objective of this study is to understand the perceptions of pre school teachers working in the city 's schools about how they perceive the ongoing formation process offered by the Education Department, after the implementation of Law 12.796 / 13 and the compulsory offer of Early Childhood Education From the age of four in the Municipal Education Network of Sorocaba (SP). Necessary or necessary referrals to the new demands of this level of education from semistructured questionnaires and interviews with teachers of the municipal teaching network. The procedural basis for the development of this research will include the bibliographical survey of the theme, the contextualization of the new organization of basic education in the national and municipal sphere through official documents. The theoretical basis was anchored in Rosemberg (2003), Kramer (2003), Real (2000). Empirical research will be oriented to the analysis of content based on Bardin (2009). We chose the quantitative and qualitative approach Minayo (1996), because it is an investigative approach, whose primary concern is to understand the phenomenon, to describe the object of study, to interpret its values and relations, not dissociating the thought from the reality of the social actors where researcher and researched are recurrent subjects, and as a consequence, active in the development of scientific research. This research may also contribute to the development of similar works in other regions of Brazil, due to its timeliness and relevant recurrence.

    One of the great challenges for the bean crop is to increase productivity and, at the same time, improve fertilization management using new technologies. The objective of this work was to evaluate the effect of residual fertilization of the winter corn crop on the productivity and biometric parameters of the common bean crop (IPR Campos Gerais cultivar), sown in succession. The experiment was conducted in the experimental area at the UFSCar - Center for Agricultural Sciences. The treatments were arranged in a 2x3+1 factorial scheme, with four replications, with the source factor of primary macronutrients at two levels, conventional mineral (M – added in the form of simple fertilizers, in proportion equivalent to 05-17-10) and organomineral (OM - Farture® 05-17-10), the dose factor in three levels, and the control without the addition of fertilizers: T1 - control (0 kg ha-1); T2 - 200 kg ha-1 of OM (equivalent to ½ DR); T3 - 400 kg ha-1 of OM (recommended dose - DR); T4 - 600 kg ha-1 of OM (equivalent to 1½ DR); T5 - 200 kg ha-1 of M; T6 - 400 kg ha-1 of M; T7 - 600 kg ha-1 of M. At 80 days after emergence of the bean plants, the following parameters were evaluated: phytomass (kg), number of grains per pod, pod length (cm), number of pods per plant, mass of 100 seeds (g), and production (g 10 plants-1). At the flowering stage (R1, 44 days after plant emergence), plant tissue was collected for analysis of foliar macronutrient contents. The results were submitted to analysis of variance and, when significant by the F test (p<0.05), they were evaluated by the Scott-Knot test (p<0.05). The types and different doses of fertilization, used in the winter corn crop, did not interfere on the biometric parameters and production of the bean plant. The leaf contents of P, K, Mg, and S were lower than those considered adequate for the bean crop. However, it was concluded that the residual effect of corn fertilization, regardless of type and dose, ensured high bean yields, which ranged from 3,200 to 4,315 kg ha-1.

    It is a fact the interference of strategic interests in education, in many cases reduced to the ‘middle’ condition for the achievement of political and economic ends. Because of this, the dissertation presents the communicative action as a proposal for reflection and delimitation of the existing interests between system and culture. Because it is a documentary research guided by a specific bibliography, we sought to develop the text through the analysis of the Habermasian bibliography, with the objective of extracting theoretical problematizations on the question of quality in education. Another methodological aspect was the interdisciplinary treatment of the theme with focus on education. Based on the literature review, we proposed the construction of a reference for pedagogical action in education, as follows: 1. to present the premise that for each type of reason there is a specific type of action: instrumental reason (paradigm of consciousness) proposes the so-called strategic action, guided by functional rules aimed at the success and effectiveness of action; and communicative reason (paradigm of intersubjectivity), in turn, proposes the communicative action, based on rules of symbolic interaction (debate) that aim at establishing criteria for mutual understanding (consensus). 2. To expose the instrumental dimension in the concept of quality in education, starting from an economistic vision. 3. Adapt Habermas’s theoretical framework to the field of education, especially his conception of communicative action, as a proposal for decolonization and re-signification of the mechanisms of social and systemic integration present in the school institution. Based on Habermas’s theory, we will take into account the hypothesis that communicative action can promote the potentialization of basic elements for democratic debate, with an end to understanding, in order to prevent the instrumental character of the unilateral constraints present in the procedures pedagogical and thus ensure learning that aim not only at market logic, but at the experience of normative interactions (referring to the social world) and expressive (referring to the subjective world).

    The indigenous education in Brazil has its founding milestone in the first catechetical actions of the Jesuits in the second half of the sixteenth century. In this long trajectory up to the present day the education of the indigenous peoples that inhabit the Brazilian territory has been the object of controversies and discussions at the governmental and academic levels, which has generated numerous studies. It is in this context of the scientific production on indigenous education that the research carried out in this thesis is inserted. The research questions that guided the research were: What are the main aspects covered in the scientific literature on indigenous education considering the public education policies of the country aimed at this population? How does the scientific literature on indigenous education stem from academic theses and dissertations? The research had as general objectives: To identify and analyze the conceptual and legal bases of indigenous education in Brazil and to draw a historical panorama of the public policies directed to the indigenous population of the country; To analyze the scientific literature on indigenous education in theses and dissertations defended in the country and their respective citations through the approaches of narrative revision and bibliometry. The corpus analyzed was composed of 173 postgraduate studies defended in the country between 1996 and 2014, composed of doctoral theses (n = 72) and master's dissertations (n= 101), as well as their respective citations (n= 8.111). As methodological approaches were adopted the narrative revision and the bibliometric approach of the analysis of citations. We chose a methodological outline composed of five studies, according to the methodologies, objectives and main results described below. Study 1, of narrative review, compelled the extensive scientific production produced by researchers dedicated to studying the subject of indigenous education published between 1975 and 2014, represented by theses and dissertations (n = 17); Books (n= 3) and collections (n= 33), articles (n = 13); Dossiers (n = 8), and scientific events (n = 9). Data were collected through retrospective and prospective searches in theses and dissertations, in SciELO and in Google Scholar. The results obtained resulted in a theoretical essay that allowed tracing the main concepts and legal aspects that underpin the research on indigenous education in the country focusing on the main views of the authors that reflected on this theme. Study 2 outlined a bibliometric view of the 173 postgraduate studies considering the following variables: profile and gender of authors and counselors; Year of defense and academic level (master's, master's and doctorate) of the works, areas of knowledge, institutional linkage of postgraduate programs, distribution of institutions by geographic region of the country, and ethnics focused on the works. Study 3 analyzed the citations (n= 8.111) present in the 173 postgraduate studies in order to identify the authors, the documentary typologies (books and articles); The languages of the publications; The areas of knowledge and titles cited. Study 4 analyzed the authors' productivity (n = 2.377) and articles (n = 1.336) cited in the 173 postgraduate studies, which allowed the identification of the research front of authors from the areas of Education and Other Areas Of knowledge that make up the literature on indigenous education. Study 5 identified and analyzed the average life, obsolescence, and annual loss of the literature on indigenous education cited in postgraduate work. The results pointed out that the average lifetimes of literatures in the areas of Education (18,83 and 11,81 years for books and articles) and in the Other Areas of Knowledge (18,70 and 12,39 years for books and articles ) Being that these literatures can be considered "classic". The annual aging factor of the two areas was the same (96%) and the annual loss of both literatures was equal (4.1%). In summary, the final results confirmed the two hypotheses of this thesis, namely: first, the literature review and the results of studies 1 and 3 showed that the scientific literature that bases the research on indigenous education reflects public policies aimed at The indigenous population of the country, especially those implanted after the promulgation of the Constitution of 1988 that guaranteed to the natives the right of a differentiated education; Secondly, the results of studies 2 and 4 showed that the area of Education is the majority in the scientific production of indigenous education, yet an interdisciplinary theoretical framework based on other areas of knowledge prevails in the works, since a wide diversity of Thematic areas and a research front composed of authors quoted from various fields of knowledge.

    The objective of this work is to investigate the characteristics of the legislative production of the deputies from 1995 to 2010 and to seek indications of association between this and government coalitions. The problem is as follows: what are the characteristics of the legislative production of deputies from 1995 to 2010? Are these characteristics associated with Executive coalition qualities? The argument is that the laws of the deputies are regulatory and of high scope due to the control of the legislative agenda that the Executive Power exercises and that these characteristics does associate with the coalitions. The methodology is mixed, with a qualitative classification, quantitative descriptive analysis and the use of descriptive statistics and statistical inference methods. It was analyzed all the legislation with divided competence proposed by deputies and approved in the period from 1995 to 2010 (Projetos de lei e projetos de lei complementar), and classified according to their subject and scope. Altogether, there are 535 laws that are segregated by legislature to be compared with each other, with government coalitions and with the party of the president so that as hypotheses raised are to be checked. Finally, it is intended, from the data, to elucidate the role reserved to the parliament in the institutional regime in force in Brazil regarding the legislative production, in addition to contribute to a better understanding of the consequences of coalition presidentialism for a relationship among the powers.

    This thesis aims to investigate the intersection between the theological-political sphere and the subjectivation process in the modern era. Through genealogical procedures, it was intended to inquire the birth/origination of fundamental concepts in the field of contemporary theology-politics, such as sovereignty, State and bare life which are present in the late Middle Age and the beginning of modern era. That was done by analyzing how the modern State machinery and its images are structured and function through subjectivizing discourses. The analysis of the narratives of the concept of “glory”, alongside to the concept of “sovereignty”, are going to be the guiding lights of this thesis, through the perspectives that have helped to detach the concept of “sovereignty” from the traditionally conveyed images in relation to the State and to the modern legal order.

    The monitoring of areas in process of restoration is a permanent challenge to be studied. Ecological integrity should assess whether the characteristics of the restored area, its size, its layout in the landscape, floristic composition and structure allow the ecological processes that can persist in the long term to function. Therefore, indicators must contain several measurable parameters such as replicability, sensibility to changes over time and easy to apply and interpret. This work intends to discuss and analyze multicriteria protocol developed with the aim of identifying efficient indicators to evaluate the establishment of ecological processes essential for the self-sustainability of the restoration. In order to do so, we analyzed indicators that reflect the stability and resilience of the area related to diversity (diversity, equitability, richness) and community structure (height, diameter, bifurcation, stratification) and functional diversity (epiphytes, herbaceous and regenerating soil cover, % of species by ecological group, height and % of cover area with litter). The reliability to maintain productivity in the long term was evaluated by: (A) management and protection (presence of termites / ants and vines), (b) anthropic impact (presence of grazing, trails and paths and exotic species), and (c) incidence of light in the soil and 1 m from this. The protocol was applied in two reference areas (fragment of Seasonal Forest at the initial stage of regeneration and one restoration at 6 years) and in 10 restoration models with two years of age, with variation in the proportion of pioneers and non-pioneers and in different densities. The main problem of the protocol of indicators was its application and interpretation in the field, requiring training for its use. The indicators were selected from the analysis of main components and, among them, 61% were redundant or with low sensitivity for the conditions evaluated. The most sensitive indicators for the differences between the areas were soil cover with herbaceous-regenerants and litter, light incidence in the soil and the proportion of non-pioneers. The main characteristic of this protocol used in this work is the ease of its application, but it needs the previous taxonomic knowledge of the species used and their respective ecological functions.

    The implementation of sustainable practices has been driving changes in business performance measurement systems, raising opportunities and challenges. Following the Triple Bottom Line concept, this thesis addresses the social dimension of sustainability. The primary focus is the external social sustainability and the impact measurement of sustainable social practices. Thus, the aim is to propose elements of a structural framework for measuring the sustainable social performance. The theoretical propositions are based on a literature review that grounded the elements proposition. The framework links the elements of social objectives deployed from stakeholder demands identification, short and long-term social goals, social sustainability performance measures for measuring the impact, and measurement of internal and external aspects of social sustainability. The research design was the multiple case studies in companies with different level sustainable social practices. Empirical evidence from case studies support both the theoretical propositions and the proposition of elements for the social sustainability performance measurement. Such elements allow measuring the social impact of sustainable social practices and identifying the stakeholders' role in selecting the sustainable social performance measurement. Those results are the first step in both improving comprehension and proposing the elements to support the social performance measurement.

    The constitution of the discourse of the drug user about his image, his place and position is determined by social and historical conditions, as well it can be filled by others previous discourses, crossed by the dominant senses of the biological, manicomial and moral pattern, which can appoint the image he has about himself and about his position as a position-subject. The purpose of this study was analyzing the discourse of the alcohol users and other drugs users in treatment in CAPD AD, it was about the image he has of himself as a subject addicted to psychoactive substances, the image of the other addicted people and the place and position conceived by him. In order to get this purpose, we are based on a methodological and theorical reference which would include the ideological processes and the imaginative formations that the alcohol and other drugs users have about themselves and about their disease. Thus, this theoretical reference was based on French Discourse Analysis, constructed upon the theory of Michel Pêcheux. It is a qualitative research, developed in CAPS AD in the city of São Carlos, São Paulo. Twelve psychoative substances users who are treated by the mental heathy service participated in this study. We used a half structured interview script for data collecting and a recorder to have the conversation saved. As a result, it emerged two discursive blocks: the images which the psychoactive substances user in treatment has about himself and the discourse of the society about this subject who is psychoactive substances addicted to. It was concluded that the ideological effect and the naturalization of some senses is the interpretation that the drug user is rejected and harassed because he is a deviant person and that the speech of this subject from an evocated ideology of his discursive memory is filled by de biomedical and moral pattern.

    This dissertation presents an analysis about rural development and public policies in Fazenda Monte Alegre settlement, located in the municipalities of Araraquara and Motuca in the state of São Paulo. For the analysis about rural development the population, economic, social and environmental dimensions were discussed, discussing the relationship with the public policies necessary for this development. The study was carried out based on bibliographical and documentary research. The bibliographic research was carried out using the technique of research in the state of the art, searching the scientific articles published in indexed journals and that dealt with the themes addressed in the study. The documentary research used data from the Land Institute of the State of São Paulo (ITESP) about the Fazenda Monte Alegre Settlement in the period of 2011-2014. Based on the analysis carried out, it is verified that the rural development in Fazenda Monte Alegre Settlement is directly related to public policies. In other words, the dimensions that have characteristics of rural development are those in which public policies are present. Thus, investments are required by the Government to guarantee rural development in all areas of rural agrarian reform settlements.

    In the last decades volatility has become a very important concept in the financial area, being used to measure the risk of financial instruments. In this work, the focus of study is the modeling of volatility, that refers to the variability of returns, which is a characteristic present in the financial time series. As a fundamental modeling tool, we used the GARCH (Generalized Autoregressive Conditional Heteroskedasticity) model, which uses conditional heteroscedasticity as a measure of volatility. Two main characteristics will be considered to be modeled with the purpose of a better adjustment and prediction of the volatility, these are: heavy tails and an asymmetry present in the unconditional distribution of the return series. The estimation of the parameters of the proposed models is done by means of the Bayesian approach with an MCMC (Markov Chain Monte Carlo) methodology , specifically the Metropolis-Hastings algorithm.

    With the increased use of devices such as computers, tablets and smartphones by people and the diversity of platforms these devices arises the need of developing cross-platform applications, in order to the same application can be run by the user from any device. In this context, the applications must support some data synchronization mechanism so that users have access to the same information in an application independently of which device is in use. For there to be synchronization, the existence of a location on the Internet for storage and centralization of data can be required, which is accessible to all devices. The availability of Internet on devices is a critical point, especially on mobile devices, which can happen loss of connection; therefore it is important that applications deal with the issue of working offline (when there is no connection). This work proposes creation of an API based on JavaScript and HTML5 in order to support development of hybrid cross-platform applications. The features of the API include the data synchronization and offline operation of application. It also proposes the use of a web server for storage and centralization of data and the use of microservices developed in Java with Spring Boot framework to synchronize data between the API and the web server.

    Music is present in the human being's life from the mother's womb due to the baby's perception of external sounds, which create a sound universe during pregnancy that makes him a listener and an apprentice. Since then, hearing and affective familiarities have been created through music. While expressing language, music also generates sensations, learnings and builds memories. The presence of music in teaching practice in the Early Childhood period allows the child to have more possibilities for expression and learning in different aspects of her/his process of discovering the world and herself/himself. Based on this premise, the work investigated the importance of working with music in the segments of Early Childhood Education. This is a research has a qualitative approach and bibliographic character, having searched for sources of information in articles, books, dissertations, theses and carried out an analysis, comparing its contents, comparing results and reaching broader understandings on the theme.

    Estudo computacional do líquido GVL (Gama-valerolactona): Influência da quiralidade nas propriedades termodinâmicas

    Besides its properties as a “green solvent”, organic molecule Gamma-valerolactone is also a chiral compound, presenting potential applications in enantioselective processes. Once obtained the adequate parameters for liquid phase simulations, different computational models were employed in order to investigate how chirality influences its thermodynamic properties. Under thermodynamic equilibrium, neither energetic nor structural differences between GVL racemic mixture and its enantiomeric pure counterparts were observed. Analysis of the most stable dimers extracted from a Monte Carlo simulation of the racemic mixture revealed subtle interaction energy differences when homochiral (RR and SS) pairs were compared to heterochiral (RS and SR) pairs, which indicated a subtle energetic preference for the homochiral ones. On the other hand, significant chiral discrimination were obtained using nonequilibrium methods. Solvation process for both R and S enantiomers of 1-chloro-1-aminoethane (CAE) in liquid SGVL via Thermodynamic Perturbation Theory resulted in a chemical potential nearly 3;3 kJ mol-1 lower for R-CAE when compared to S-CAE, indicating that the utilization of GVL as a chiral liquid could increase the yield of processes involving chiral species in condensed phase. Binding process of GVL molecules giving rise to both homochiral (SS) and heterochiral (SR) dimers in vacuum, via Umbrella Sampling method, could show that although both pairs had similar binding free energy values, major differences could be observed on these free energy profiles when higher molecular contact was imposed by Umbrella Sampling spatial confinement. Such binding process of GVL molecules was also studied in both RGVL and SGVL liquids. Thus, although lower binding free energy values were obtained, a nearly 20 % difference could be observed due to solvent chirality.
