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.

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.

Defining when an agroecosystem can be considered healthy is one of the challenges faced by both family farmers and extension workers and researchers. There are several methodologies of visual evaluation of indicators that indicate their health and the first chapter is a bibliographical review on the methods of visual evaluation of the soil. The second chapter deals with a fieldwork in which seven methods for the determination of soil visual assessment indexes (IAVS) in six different soil uses, including the Visual Soil Health Assessment Method (AVSS), modified in this research and with emphasis on edaphic macrofauna. The study was carried out at the São Sebastião site, located in the city of Terra Roxa (SP) in areas of riparian forest (MCI), agroforestry system (SAF), organic sugar cane (CAN) and orchard (POM), all in Red Latosol, in a permanent preservation area (APP) and pasture (PAS), both in Gleissolo. MCI and SAF and APP treatments, which had greater plant diversity and tree species, had the highest IAVS. The AVSS proved to be useful and highly sensitive in the evaluation of soil quality in the different management systems analyzed in the property. The third chapter discusses the use of soil macrofauna as a soil health bioindicator and how it can be included in soil visual assessment methods in a simple and accessible way for farmers. Ten groups of edaphic macrofauna were found, as well as eggs and larval stages, including animals that perform several ecological functions in the soil. The diversity of macrofauna was higher in the areas that received the highest indices in the visual evaluations of the soil. The SAF presented the highest diversity of invertebrate macrofauna in the soil. Soil management and tillage systems affect the structure of the dominant taxonomic groups of the edaphic macrofauna. Soil fauna can be used as a bioindicator of soil health.

The purpose of this study is to describe the current conditions of the school support system that Brazilian Countryside Early Childhood Education students are provided with. This study was conducted at schools in the state of São Paulo, Brazil, in a period between 2007 and 2015. The study analyzed data samples of eight cities within the Regional Board of Education in the Bragança Paulista area. The data samples were collected in a micro-data database from Scholar Census. The eight cities within the Regional Board of Education in the Bragança Paulista area presented the highest school enrollment rates in the state of São Paulo. This study initially presents considerations about Brazilian Early Childhood Education and Countryside Education histories to contextualize the study and set the study’s goal. The study shifts focus to how Brazilian legislation assures the Countryside Early Childhood Education, verifies how the legislation prescribes the students’ rights and understands the influence of International Organizations in drawing up these documents. Lastly, the study analyzed the scholar micro-data in the proposed period, where it was assumed that there were improvements in the Early Childhood Education in the studied area. However many of the schools still lacked fundamental infrastructure conditions, physical resources and electronic devices. In conclusion, the study indicates the importance of educational policies that benefit countryside citizens and the Countryside Early Childhood Education as well as public educational funding to enable better quality regarding the Early Childhood Education.

Currently, it is not a trivial task to point out a test that can diagnose accurately enough a patient with Parkinson’s Disease, as well as it is quit difficult to assess the level of the disease. Experts recommend the application of different types of tests, many of them based on signs and biomedical imaging, such as electroencephalogram, computed tomography and magnetic resonance to aid the detection of the disease process, since as the age ranges, symptoms such as fatigue and weakness can hide diagnosis. In order to provide a more effective clinical information to doctors aiming at diagnosis with greater confidence, methodologies to perform the fusion of different imaging modalities have become increasingly popular and promising. Recently, the use of forms containing some activities using a biometric pen with multi-sensors have been applied for the detection of Parkinson’s Disease by means of handwriting analysis. However, information derived from the scanned image of the form itself, and the one obtained by same pen have not been used together for this purpose. Thus, this proposal aims using pattern recognition techniques and image processing aimed at using the information from the form together with data from the pen. We believe a possible improvement in the medical diagnosis of Parkinson’s Disease can be archived. Another contribution of this proposal, is the design of a multimodal database to aid in the diagnosis of Parkinson’s Disease.

In the last decades, the emphasis and application of the principles of Green Chemistry have inspired a change of behavior, both in industry and academy, towards a more sustainable chemistry aiming the synthesis of the desired product with a lower number of steps, high yields and the use of nontoxic hazardous chemicals. In this context, the increasing recognition of the environmental benefits originated from the visible-light-induced photochemical reactions, when compared to the thermal conventional methods, is motivating the scientific community to develop new photochemical approaches that are more efficient and simpler to operate, focusing on the development of new strategies for the synthesis of biologically active organic compounds. Efficient synthetic approaches for the formation of heterocycles based on indolines, 2,3-dihydrobenzofurans and 6-(trifluoromethyl)phenanthridine were developed through radical cascade reactions promoted by visible light. In addition to synthetic development, the mechanisms of the reactions were also investigated by a set of controlled experiments, spectroscopic studies and characterization techniques.

Counterfactual thinking is a type of imaginative thought, usually characterized by “What if” thoughts, in other words, hypothetical alternatives to reality, commonly spontaneously elaborated by negative or unexpected events. There are some functions of counterfactual thinking that are important for adaptation, such as re-elaboration about everyday life. Some researche indicate that the function of this type of thought can be a handicap. The objectives of this study were to: (1) compare counterfactual thinking of undergraduates with and without signs of depression, to verify if there is any difference in the way they think about alternatives to reality and (2) verify what kinds of activities to generate counterfactual thinking are most effective. Participants were 145 undergraduates, with an average age of 22,1 years. For the comparison sample, the students were divided in two groups, according to their scores on the Beck Depression Inventory: people without signs of depression (less than 8 points) and people with signs of depression (more than 12 points). Participants answered identification questions, the Beck Depression Inventory and the Counterfactual Thought Evaluation Technique (including a self-report measure and three stories). Participants answers was categorized by content analysis and the frequency of each category was compared using between groups t-Test. Participants with signs of depression wrote more self-reports about affective relationship and participants without signs of depression wrote more self reports about academic situations. In general, the style of counterfactual thinking showed few statistical differences between groups. Counterfactual self-reports presented the greatest differences, and indicate that people with signs of depression tended to elaborate more counterfactual thinking than people without signs of depression, when they reflected on their situations. For the self-report, counterfactual thinking was, in general, categorized as upward, additive, self referent and based on an action/inaction. For the three stories, there was no difference between the styles of counterfactual thinking between the two groups and their responses were categorized as mostly upward, subtractive, self referent and based on an action/inaction. Only the story with a positive outcome led to more downward counterfactual thinking. From this research, concludes that people with indicative of depression tend to generate more counterfactual thoughts than people without indicative of depression, especially when they think about self-report and stories with negative outcomes. The style of counterfactual thinking described by both groups presented the same pattern, which indicates that the style of counterfactual thinking may not be related to maintenance or development of depressive symptoms.

Alzheimer’s disease (AD) is currently the most common type of dementia, characterized by a progressive loss of memory and deterioration of cognitive functions. Most approved drugs for AD treatment are acetylcholinesterase (AChE) inhibitors (AChEI), mainly responsible for reduced rates of the neurotransmitter acetylcholine (ACh) in the synaptic process. In this context, organic synthesis, specially the synthesis of heterocycle compounds, plays a key role in drug discovery, since these compounds are related to a broad spectrum of biological activity. In the last decades, the use of continuous flow reactors in organic synthesis stands out as an important tool for developing safer, more efficient and sustainable methodologies. This thesis is focused on the synthesis of coumarins, hydantoins, indoles and pyrroles derivatives, aiming to obtaining potential AChE inhibitors. When possible, the synthesis of such compounds was conducted employing alternative methodologies based on green chemistry concepts, aiming to decrease the synthetic steps, use alternative energy sources, e.g. microwave reactors, substitute toxic solvents or even apply solvent-free protocols, and use continuous flow reactors. Initially, a new method was developed for the one-pot synthesis of high structural complexity piperidinocoumarins in good yields and selectivities, trough asymmetric organocatalysis followed by an Ugi-Smiles type reaction. One alternative route was also employed for the synthesis of reduced hydantoins over tree steps, starting from asymmetric aziridines. Also regarding the hydantoin’s synthesis, it was developed a continuous flow protocol of the Bucherer-Bergs reaction to afford 5- and 5,5-disubstituted hydantoins faster, safer, and more efficient when compared to the conventional methodology. Finally, we developed a protocol for the trifluoromethylation of indoles and pyroles under continuous flow conditions, based on the Minisci reaction, using perfluor halides as starting material. Aiming to collaborate with the structureactivity studies of the coumarins against AChE, hydantoin-coumarin hybrids were synthesized. All compounds were evaluated against AChE and showed low to moderate enzymatic activity.

Faced with the increase in vegetable production in Brazil to 16 million tons and the collection of 8 billion reais in 2016, studies have begun on both planting and vegetables. Information from the market of vegetables shows that lettuce is the most consumed herbaceous in the country; However the consumption of arugula has been growing over the years and is currently a strong competitor of lettuce both in consumption and in terms of economic attractiveness.Due to this growing interest in recent years, in this study we analyze the interactions - and the effects - of electromagnetic waves in the visible light range and microwaves in the production of arugula. Through the obtained results, we developed a device that guarantees the correct color (wavelength) and light tonality to optimize the germination - and therefore the production - of the arugula.The analized samples were treated with light from light emitting diode (LED) sources at wavelengths of the visible spectrum at frequencies corresponding to red, green and blue colors and still with electromagnetic radiation in the range of micro (0.3 to 300 GHz) specifically at the 2.4 GHz frequency. These treatments were performed with the 8h LED setting, 8h of solar clarity and 8h night, while the 2.4 GHz treatment remained irradiated for 24h, receiving 12h of solar clarity and 12h night. Control samples were submitted to 12h of solar clarity and 12h night. All samples were treated for 7 days.The biometric measurements (leaf size, aerial part and root), fresh mass, dry weight and humidity percentage, chlorophyll a, b, total and carotenoid measurements and quantification of macro and micronutrients as Calcium (Ca), Iron (Fe), Magnesium (Mg), Manganese (Mn), Copper (Cu), Potassium (K), Sodium (Na) and Zinc (Zn).The results shows that red LED light obtained better results in biometric characteristics, wet mass and macro and micronutrient values than indicated by ANVISA through the IDR (Recommended Daily Intake) index.The low-cost device developed, proved to be important for identifying and aiding in the parameterization of light through the appropriate use of each color and tonality of the electromagnetic radiation used, thus promoting different responses in the culture. The intellectual protection of this device with the INPI (National Institute of Industrial Property) has already been initiated through the Innovation Agency of UFSCar.The results obtained in this work with the red LED will allows the extension of this project to more sophisticated studies involving the concept of quantum coherence, as recently pointed out in a study published in the Nature journal.

Infectious pneumonia is a major cause of morbidity/mortality, mainly due to the increasing rate of microorganisms resistant to antibiotics. Photodynamic Inactivation (PDI) is emerging as a promising approach, as effects are based on oxidative stress, preventing the emergence of resistant microorganism strains. In previous studies, the in vitro inactivation of Streptococcus pneumoniae using indocyanine green (ICG) and infrared light source was successful, and achieved reduction of 5 log10 colony-forming units (CFU/mL) with concentration as low as 10 μM ICG. In the present study, a proof-of-principle protocol was designed to treat lung infections by PDI using extracorporeal illumination with a 780 nm laser device and ICG as photosensitizer. In a first row of experiments, hairless mice were infected with S. pneumoniae and PDI was performed two days after infection. For control groups, CFU recovery ranged between 103-104 CFU/mL/mouse. For PDT group, however, no bacteria were recovered in 80% of the animals. Animal survival was evaluated separately over 50 days. No deaths occurred in PDT group, whereas 60% of the control did not survive. Lung injury analyses were performed in BALB/c mice, the bacteria reduction were 2 and 4 log10 in 2 mice (5 in total) and the wet-to-dry ratio showed that PDI did not increase the edema in lungs. The bronchoalveolar lavage data indicated a larger absolute number of cells (mononuclear and polymorphonuclear) in the PDI group in contrast to control group, meaning that the technique could increase the immune system response. In vitro results showed the irradiated ICG could generate aggregates or photoproducts that help PDI to inactivate the bacteria. Our results indicate that extracorporeal PDI has potential for pneumonia treatment, and pulmonary decontamination with PDI may be used as a single therapy or as an antibiotics adjuvant.

It is a study about the social meanings emerging from the monetary policy action of the Central Bank of Brazil (BCB) between 1995 and 2016, using comparisons with agents of the Federal Reserve (Fed), European Central Bank ( ECB) and pressure groups inserted in a broader social space, aiming to understand the social meanings of decision making on such a policy, based on structural and moral inheritances throughout the historical process of the role of the Central Banks. Under the sociology of Boltanski and Thevenot's critical capacity, supported by the prosopography, narrative, content, and financial statements methods, by reference to situational disputes over interest rates, it was possible to demonstrate that there are moments in which there is convergence between the position and the Position at the BCB, while at other times they influence more public-economic-financial coalitions or the performative pressure of groups outside of power, especially in cultural disputes that open up larger areas of opposition, opposing Hawkish practices to practices Dovish (monetary easing), emerging moral senses of accusation and defense. Finally, it was concluded that the monetary counter-performance between 2011 and 2014, contrary to the equivalence agreements in monetary policy, was one of the important variables for the establishment of a political crisis, along with other multisectorial factors. To this end, this tension has indicated a meta-heuristic operator of interest and debt which anchors high interest in technical-moral justifications, as justification in the "sacrifice" and "just reward" to financiers and as "punishment" to the "irresponsible".
