The Cu catalysts activity is modified by reducible supports, such as cerium and praseodymium oxides. The interaction of these oxides with Cu nanoparticles prevent agglomeration and generate active interface sites. The relationship between structure and reaction velocity have been calculated from model catalysts that have properties very far from a real catalyst. One of the great challenges is the understanding of ceria and praseodymia effects on the modification of the properties of copper catalytic sites. The activity - structure relationship during the water gas reaction for supported copper catalysts in interaction with cerium or praseodymium oxides or not was investigated on this study. Through in situ studies, it was found that for the Cu/Al2O3 catalysts the growth of the metal particle, caused by the increase of the Cu content supported in the alumina, led to a decrease in the oxygen coating degree. Which, in turn, generated an increase on the surface electron density of the particle resulting in the elongation of the Cu-O surface bonding distance. When different ceria or praseodymia contents were added to the Cu/Al2O3 catalysts did not cause significant changes in particle size and the oxidation state of copper. However, the oxide-metal interaction resulted in an increase on the surface electron density of the copper particle causing an increase in the Cu-O bond distance over the non-promoted catalysts. A linear correlation between Cu-O binding distance and catalytic activity for WGSR is observed. Therefore, Cu-O bonding distance reflects the electronic properties and activity of copper sites.

This paper aims to explore the advance of the diffusion of the financial logic on the national clothing retail in the promotion of consumer credit in Brazil. In this sense, it looks to verify how this advance is configured in a new organizational arrangement that is signed by the formation of partnerships between the financial institutions and the retail companies, as well as to analyze the administrative strategy to manage this new model, in view of its Social and labor implications. We analyzed eight companies in the national retail clothing sector that have a strong expression in consumption in Brazil, from 2008 to 2016. The companies of this sampling are Marisa, Renner, Riachuelo, Pernambucanas, Cia. Hering, Arezzo & Co, Restoque Commerce and Garment Apparel and Grazziotin Group, which previously had the commercial object of trading merchandise and today deal with consolidated variables in the financial Market. In this work, it is analyzed how the mergers and acquisitions movements involving financial institutions and retail companies are shaping the domestic market, and also how organizational models are managed after the adoption of partnerships with financial institutions and which Impacts of the expansion of this model on labor relations. The results obtained point to a better understanding of the need to adapt to the process, which requires a gradual change in the current organizational structure and consequent prevention of damages related to labor issues, values added to shareholders or positions of CEOs, obliged to increase a series of variables that result in change in the segment. These factors exemplify the materialization of financialization strategies among the largest national apparel retailers, and also show how the banking process is affecting the profile of the commercial model of the national retail sector.

In this thesis we tackled two di erent problems of quantum integrability. We derived nite sets of non-linear integral equations to describe physical properties of quantum chains invariant under the super-algebras su(2|1) and osp(1|2); and we also studied the in uence of boundary conditions on the bulk properties of the six-vertex model. The su(2|1) invariant model is a multi-chain generalization of the super-symmetric t-J model. Using the quantum transfer matrix method we obtained the phase diagram. For the osp(1|2) invariant model we could also rewrite the Hamiltonian in the language of itinerant fermions interacting through exchange, although the Hamiltonian itself is not hermitian, which corresponds to a non-unitary eld theory. We analytically computed the (e ective) central charge of this theory, corroborating numerical results of the literature. These results point towards the possibility of generalization of such non linear integral equations for models of di erent symmetries. Concerning the problem of the in uence of boundary conditions on the six-vertex model, we showed the existence of in nitely many boundaries whose intensive properties disagree with the standard periodic boundary condition SPBC = 32 ln(43). We also proved that by a suitable choice of boundary conditionsany entropy value in the interval [0, 12 ln(3324)] is accessible. We conjectured that the sameis true for the interval [ 1 2 ln(3324), SPBC]. The number of configurations of the six-vertex model with fixed boundary condition amounts to the enumeration problem of generalized alternating sign matrices.

Food security has been a constant concern in the world since the mid-twentieth century, manifested by world leaders in the post-war period and materialized in the holding of the United Nations Conference on Agriculture and Food in the creation of the United Nations Food and Agriculture Organization ( FAO) in October 1945. Food and nutritional security has emerged as a matter of great importance and interest, as it is the means that seeks to guarantee the right to food for people and individuals, with an emphasis on the most vulnerable groups. To improve the efficiency of Food and Nutrition Security, it is necessary to create opportunities for follow-up, monitoring and evaluation of public policies that allow to guarantee impacts at their levels. This is not possible without the participation of government agencies, civil society, private sector and international cooperation in the whole process from conception to evaluation. . The PAA is a component program of a set of public policies related to the fight against hunger and poverty. Its objective is to enable improvements in the socioeconomic indicators of farmers' families, thus helping to improve their quality of life. It is concluded that there is still much to improve the PAA program at the Elizabeth Teixeira camp. There are many shortcomings that make the PAA program not have the impact it should have.

Cutaneous melanoma is one of the most feared cancers worldwide due to resistance to treatments and the high capacity to develop metastases. Photodynamic therapy (PDT), a minimally invasive therapeutic modality, is a promising treatment strategy for malignant and non-malignant lesions. Ru (II) polypyridine complexes are interesting photosensitizers for PDT due to their unique spectroscopic and anticancer properties. This study reports the extension and implications of medium on the aggregation process of the [Ru(phen)2(pPDIp)]2+ complex (RupPDIp), where phen = 1,10-phenanthroline and pPDIp = perylene pendant group functionalized with one of the coordinated phenanthroline ligands) and its consequences on photochemical and photophysics properties. Excitation with visible light leads, initially, to emission of both chromophores inside the same molecule: 3*MLCT (Ru,dπ→phen,π*) and 1*ILCT (pPDIp,π→π*); however, the medium induces increased π-π intermolecular interactions that lead to generation of the pPDIp moiety in the radical anion forms pPDIp•- in DMSO, pPDIp•- and pPDIp2- in cellular culture medium RPMI, and 3*pPDIp in buffer solution (pH 7.4), and starch films. Thus, it is demonstrated that variation of solvent alone can be used to tune the energy of the excited state in a manner that leads to systematic variations in the photoreactivity and emissive properties of the complex. The complex also exhibited an interesting profile for biological activity with the activation of singlet oxygen (1O2) in buffer solution (pH 7.4) under irradiation by different light systems. The potential of the complex for application in photodynamic therapy to B16F10 murine melanoma cells in vitro was also evaluated. No cytotoxic effects were observed at concentrations of the complex of less than 10 μmolL-1 in the dark. However, the complex showed a significant photocytotoxic effect presenting IC50 values of 0.5 μmolL-1 when treated with 420 nm light at a dose of 0.58 J.cm-2 and 1.2 μmolL-1 when treated with 518 nm LED light at a dose of 0.11 J.cm-2. These results demonstrate that RupPDIp is a promising candidate for the application of photosensitization in photodynamic therapy. In order to facilitate the application and control of RupPDIp as an antitumor agent, the complex was immobilized on a cassava starch-based polymer film. Spectroscopic assays demonstrated that the complex adhered to the π-π aggregate form when immobilized on the film, maintaining its luminescent properties and activation of 1O2 with exposure to light. In vitro and in vivo biological assays did not show significant results in antitumor activity due to the 1O2 limited action radius, demonstrating that the film is not the most suitable drug delivery medium.

To study the Elderly Councils assume in the comprehension of the historical context in which the Councils of Rights appeared. The Elderly Councils are part of a protection network, once they are participative instances in the defense of their rights. In this sense, two important legal lines are highlighted, the National Policies for the Elderly, which institutionalized them, and the Statute of the Elderly, which ratify them. In this way, it is presented the subject of the social participation which refers to sharing the power of decision regarding public subjects in these participative spaces (TATAGIBA 2002, GOHN 2002,2011a), after and before the 1988 Federal Constitution. The objectives of this research are to comprehend the structures and the operation of these Councils, to present the areas in which the demands of the elderly population were evidenced on three Conferences of the Elderly People Rights, and to analyze an Elderly Council located in a city in the State of São Paulo. The research is part of the qualitative methodological framework characterized as a case study (Godoy, 2006). The results demonstrated that it was possible to understand the singularity and particularity that were present in this Council, and from this understanding, a booklet was developed in order to extend the knowledge to other Councils that identify themselves with this problematic. The social relevance of this research is the possibility of presenting an educational action for the members of the Elderly Municipal Council and contribute with the performance of the tasks of the Council members.

Dynamics of automatic vehicle movement (Automatic Guided Vehicle), its associated with your control system, and the adoption of traditional control techniques, whose parameter and tuning are performed based on linear gains constants of this systems, may presents satisfactory performance and results in linear moments. However, when considered moments, phenomenon of dynamic movement is present, control systems with linear characteristics are insufficient. With these problems, its necessary adoption of control systems able to adapt to these parameter variations. The object of study in this research is a AGV follow line with differential traction, using adaptive fuzzy control systems, whose aim to reduce errors in trajectory tracking, looking for results of accuracy and precision of the vehicle in the follow of trajectory. The adaptive fuzzy control technique applied to the phenomenon of vehicle movement, mapping it intuitively through linguistic variables. As a method of comparison, is applied classic control technique PID, and used to validation adaptive fuzzy control technique with comparison of results on test scenarios, with different roads proposed to vehicle associated with weight variation. It was possible to verify that the control results when applied to control orientation of AGV, vehicle achieves stability and keeps its errors close to the reference systems value, however in the PID control system the orientation errors are visible during the trajectory tracking and through graphical perspective analysis, showing that the PID control system is not adaptable to weight and track variations. Another point of feasibility of applying the adaptive fuzzy control system, within the application is the tuning of its parameters, which once adjusted were sensitive to the variation of load and trajectories managing to maintain rates of errors up to 80% smaller them to the PID control, validating the research and demonstrating the applicability of adaptive fuzzy control systems within the problem domain.

The National Policy of Solid Waste (NPSW), instituted by the federal law nº 12.305/2010, establishes the guiding principles, legal instruments and objectives to order the actions and practices of waste management in Brazil. Among the proposed principles and instruments, the shared responsibility for the products life cycle and the reverse logistic are inducers of a new management model and a great challenge as well. To assist in its operationalization, the NPSW institutes the Sectoral Agreements (SA) and, in São Paulo State, the SA were established by the Commitment Terms of Reverse Logistics (CTRL). Seeking to bring this scenario to light, the current research proposes to present and analyze the implementation of CTRL in São Paulo State. For this, it is presented the historical of the 12.305/2010 law approval process and the waste management scenario post-NPSW. The data and information collection occurred through bibliographic and documentary review, and the CTRL case study was developed with an application of questionnaires and interviews. The State of São Paulo presents 10 signed CTRL, with 08 sectors participating in this research. Inconsistencies were identified regarding the definition of targets and the results obtained by the sectors, which adopted, in most, different metrics. The Secretariat for the Environment of São Paulo State played a fundamental role in stimulating and directing the terms, being the main responsible for establishing them juridically in a legal instrument, acting also in the definition of targets. The participation of different actors in the realization of shared responsibility is still deficient, with a greater accountability to manufacturers. The involvement of cooperatives and public authorities is not a reality yet, which have importance and role beyond the perception of CRTL subscribers. Most of the sectors use support tools (software and GIS) and affirm to have reached the established targets, having as the main difficulty the low interest and participation of the others chain members. It is concluded that the NPSW, despite the slow evolution, should stimulate new and necessary solid waste management practices in Brazil, having the sectoral agreements as a pillar for the reverse logistics and shared responsibility effectiveness.

There are few advances in research on the formation of the nurse practitioner for urgent and emergency assistance, on the epidemiological profile of the brazilian population. Networking puts Basic Health Attention with in strategic position as ordering, care. Assuming a definitive role in what relates to maintenance of the life of patients. The role of the nurse in this network, is cross because it permeates the whole route of this watch. The formation of nurses requires constant professional improvement, since this is a complex and integral action. Learning scenarios allow for greater contact with the reality of the environment in which they live, providing a horizon of paths to creativity and transformations. It is descriptive, exploratory study of qualitative approach, with the purpose of analyzing the formation of nurses in the Basic Health Attention. “in the light” of the public policy of attention to urgencies and emergencies in four graduate programs in nursing schools located in the State of São Paulo. Data analysis and discussion will occur under criteria of National curriculum guidelines were carried out through the realization of interviews semi-structured with coordinators of courses, teachers and those responsible for emergency and emergency education. As a result, we can identify that only two of the four universities have discipline specifies inurgent and emergency area, allowing for the planning and structuring of primary content to your professional practice. Universities that do not have the discipline of emergency and emergency condition theme approach to evaluation each faculty member about the importance of urgent and emergency education on graduation. Learn how urgent and emergency is a social need which reflects directly on the quality of services provided in the health system that learning is enhanced when you approach the teaching of different professions of the health area, promoting interdisciplinarity as daily practice and, thus, enhancing the care centered on the individual.

Ce travail de recherche est né de la lecture et de l’analyse d’un corpus composé par 154 textes de « vestibular ». Dans l’ensemble de ces compositions nous identifions un mécanisme d’énonciation nommé « desréférenciation » énonciative. Le choix de cette thématique, créé à partir de l’observation empirique, a été motivé par la Théorie des Operations Enonciative, qui défend l’articulation entre le langage et les langues naturelles. A partir du rapport entre la théorie et l’analyse linguistique, nous défendrons l’hypothèse que les discussions théoriques proposées par la TOE nous permettent créer des explications métalinguistiques de l’usage du déréférencement des temps verbaux dans les textes de « vestibular ». Ainsi, nous proposons une analyse linguistique des plans énonciatifs dans les textes de « vestibular », ce que nous apporte des contributions, dans la perspectif culiolienne, pour penser la production et l’interprétation des textes. Notre objectif est utiliser le métalangage culiolianne pour expliquer dans quel mesure l’emploi des temps verbaux influe dans la construction argumentative d’un texte. Dans ce sens, nous voulons mettre en évidence les parcours nécessaire pour l’stabilisation des plans énonciatifs temporels de façon à aider le professeur/chercheur à aborder les évènements de visualisation difficile quand on ne peut pas considérer la prédication comme un processus dynamique et articulé à l’énonciation. Nous explorons linguistiquement les plans temporels dans les textes de « vestibular », principalement ceux dont l’argumentation peut être améliorée ou repensée. En effet, dans ce travail de recherche, nous souhaitons penser à des formes diverses de discuter le texte de « vestibular » et établir des hypothèses par rapport les motifs dont un choix lexique grammatical peut être inadéquat du point de vue de la constitution des plans énonciatifs. Par le biais de notre réflexion, nous concluons que les opérations de localisation sont fondamentales pour constater et analyser les évènements sélectionnés et que les mécanismes énonciatifs observés ne se laissent pas catégorisés facilement.

The International Labor Organization (ILO) presents rural labor as significantly more dangerous than other activities and estimates that millions of farmworkers suffer serious health problems. The challenge of Ergonomics is even greater in the agricultural universe when supporting worker’s well-being and productivity, due to the considerable variability of situations encountered and organizational relationships. It was observed a lack of studies regarding working conditions related to the use of artifacts in manual orange harvesting, even more noteworthy in a market of great economic importance both in Brazil and the world. From a qualitative analysis, were explored the relationships between the development of manual harvesting activity and the design of artifacts in real situation of use. As methodological reference was used the approach of activity analysis, aiming to acquire knowledge, from the case study, on the different operative modes and the variabilities present in the environment, the changes made in the artifacts and the artifact transformation into an instrument, associated to the regulatory process. The research recommends design features for the construction of manual orange harvesting artifacts, embracing the vision of continuous design, highlighting the worker’s logic of skills development and artifacts’ appropriation as a way of reducing physical demand and achieving higher productivity on the journey. This study also made possible to broaden the debate about ergonomics contribution to innovation and knowledge transfer in the artifacts work design in agricultural sector.

Based on the oral narratives of Antônio Carlos, Romilda Augusta and Dinalva Aparecida, retired Physical Education teachers, in this PhD research, we analyze their life histories in the construction of the teaching knowledge in the context of the initial years of Elementary School of the state education network in the 1980s and 1990s. We chose life histories as a qualitative research, with the use of in-depth and open interviews and documentary analysis. We explain the search and selection process, the profiles of the participants and the process of construction of the analysis themes. The themes - related to the teaching knowledge that emerged from the extracurricular, school, training and professional trajectories of teachers - also settled on the data themselves and made real the possibility of apprehending several stories in the same history of life. In order to develop the aforementioned objective, themes and data analysis, we will discuss life histories, teacher knowledge and identity, teaching learning, reflection possibilities based on life histories and the context of formation - based on a curricular model "traditional-sports" - of teachers in Santo André and Bauru and of professional performance in several schools of public and private education networks in the State of São Paulo. The influence of some tendencies and the technization of Physical Education, the dependence between the reminiscences of the different trajectories of the teachers and the family, social, scholastic, religious and professional relations of each one of them and the focus in the first moment of the History of Physical Education in the State of São Paulo, where his classes were taught by a specialist teacher in the initial years, were also, among others, the object of these dialogues. We have identified in the teachers' stories knowledge from their own trajectories, we have understood the influences of the various moments and contexts of formation and work they have lived in the construction of their knowledge, we have established relationships between these knowledge, the formation received and the personal aspects of the teachers , and between training, the purposes of teaching Physical Education in the 1980s and 1990s and the characteristics of the students of the early years. The identified elements - with consideration for the time and space of training and professional performance of the participants - evidenced the process of building their knowledge throughout their life and profession trajectories, indicated successes and difficulties in their actions and contributed to reflect on the guidelines that we systematize for the initial training courses in Physical Education and, therefore, for the public policies of teacher training. As final considerations, we affirm that the life histories of the teachers indicated elements that contribute to reflect on the professional practice of teaching in Physical Education in the initial years, through the purposes of teaching, the characteristics of the students and the training gaps. These elements should therefore be considered and guaranteed in teacher training in order to meet the demands of the profession and to stimulate new studies based on this type of approach, on successful trajectories and teachers.

Multimodal interfaces are becoming more popular, and increasingly require natural interaction as a resource to enrich the user experience. Computational systems that support multimodality provide a more natural and flexible way to perform tasks on computers, since they allow users with different levels of skills and knowledge to choose the mode of interaction best suited to their needs. Among natural forms of interaction are the gestures, the natural interaction through gestures is becoming more popular, since it's an alternative to the conventional style of interaction based on keyboard and mouse, and also by the growth and advent of motion capture devices, with low-cost visual depth sensors. In this context, this dissertation presents a study about all the necessary steps for the construction of a model and tool for the recognition of static and dynamic gestures, these being: Segmentation; Modeling; Description; and Classification. Proposed solutions and results are presented for each of these steps and, finally, a tool that implements the model is evaluated in the recognition of gestures, using a finite set of gestures. All the solutions presented in this dissertation were encapsulated in the GGGesture tool, which aims to simplify research in the area of gesture recognition, allowing communication with multimodal interfaces systems and natural interfaces.

The maintenance of forest areas is one of the most established recommendations for the conservation of biodiversity and key processes in ecosystems, such as pollination. However, this is a challenge that contrasts with the need for anthropic use of natural areas. Among these uses, the growth of agricultural activity on forest areas generates a paradox for conservation. While most crops depend on pollination, maintaining pollination requires the conservation of forest areas. One of the ways to deal with this issue is to analyze the characteristics of the landscape considering the interaction between the amount of forest and other land uses in a more realistic view that includes the function of each use in the maintenance of the ecological process. This study evaluated the effects of forest quantity and landscape heterogeneity on pollination of understory plant species in areas of Atlantic Forest, State of São Paulo, Brazil. Fifteen landscapes of 1 km radius were selected in a forest cover gradient between 21 and 96% and of land use and occupation heterogeneity of 0.18 to 1.67 (Shannon Wiener). Based on the literature we infer the possible contribution of each land use to the conservation of pollinators that forage outside the forest environment. In hexagonal plots of 30m on the side we collected open flowers and recorded the number of flowers in the sampled plant. We counted in fluorescence microscopy the number of pollen grains on the stigma, the number of tubes germinated up to the upper third and to the base of the stylet of each flower. We analyzed 1048 flowers from 189 individuals and 46 species. Pollination varied widely at all levels of the system. In the analyzed landscapes the proportion of forest and heterogeneity of land uses were inversely correlated, requiring a joint analysis of both factors. The higher proportion of forest and lower heterogeneity resulted in increased pollen load, and in the flowers in which at least one pollen tube was formed, the highest number of germinated tubes for each egg (pollination success). The characteristics of the landscape did not influence the germination of pollen, the proportion of pollinated flowers in each plant, nor the pollination success when also considered flowers without pollen tubes. The result of increased pollen grains deposition and pollination success with possible consequences on reproductive success indicates that the proportion of forest in the landscape is an important feature in the conservation of the pollination process of the species studied. We evaluated the quality of pollination in the landscape as moderate, since all variables presented values between 41% and 56% of success. This good result seems to be associated to intermediate to high levels of forest cover and its interaction with a high proportion of uses that provide some type of resource and / or condition for pollinators in all landscapes. This characteristic makes them functionally similar to the sustainability capacity of the pollination function, being also a possible explanation for the absence of effect found in the other analyzed variables. Our study indicates the importance of increasing forest cover associated with good quality land uses in favor of pollination stages.

In the midst of the great effervescence of ideas, political manifestations, models and propositions of a nation in dispute, characteristic of the early 1960s, the Ministry of Education and Culture (MEC) supported a project to revise the teaching of History of Brazil. The project: the New History of Brazil, a set of monographs, carried out in a collaborative way between the Student Assistance Campaign (CASES), an organ linked to the MEC, and the Department of History of the Instituto Superior de Estudos Brasileiros (ISEB). as principal signatory Nelson Werneck Sodré. Such a revision of history teaching, launched in early 1964, was aborted months later by the dictatorship, which interrupted production, collected the work, persecuted the intellectuals associated with it, and labeled them generically as subversives. The possession of this material was attested to by subversion for the dictatorship. This present study seeks to analyze the project of the New History of Brazil in its relation with the so - called Brazilian reality. Capitalist development in Brazil did not present a single project of nation. It starts from the hypothesis that the New History of Brazil radicalized the national and anti-imperialist project and, extrapolating, the idea of the "basic reforms" in the educational field, was linked to the major project of the Brazilian revolution. Being propositive, the New History of Brazil extrapolated the field of education and teaching history, specifically, becoming more than an interrupted project, but a model to be fought.

In Brazil, the inflation targeting system has been adopted since 1999, with inflation measured through the Extended Consumer Price Index (IPCA), which in its basket of goods has products with free and administered prices. Inflation in recent years in Brazil can be explained as an inflation of costs caused by supply shocks, as well as an inertial component inflation caused by the indexation of administered prices. Among the administered prices, the electricity tariff is one of the items with the highest weight and that contributes most to the variation of the monitored IPCA. Electricity is one of the most important inputs of the national energy matrix, being present not only in the residences, but also is a primordial input for the other sectors of the economy. The present work aims at analyzing the effects that the variations of the tariff of electric power cause in the IPCA and in the categories of goods and services that compose it during the period of January of 1996 until June of 2015. To understand the behavior of the tariff of energy are estimated their determinants. The analysis of the econometric models are based in the methodology of multivariate time series. Overall, positive energy price shocks lead to an increase in the price variation of most IPCA categories. Increases in electricity tariffs also have a positive impact on the IPCA of monitored prices and services.

With the expansion of mobile computing, caused by the popularization of smartphones, tablets and application stores, and the increase in the inter-connectivity between devices and servers, many questions arise in the software engineering scenario. As most applications work with a back-end server over the Internet, one such question involves offline application usage, because in many occasions network connectivity is not available. This question can be solved in many ways, including storage of the requests, caching, data synchronization, among others. There are solutions both in the industry and academy that attempt to solve this problem, however two challenges remain: to solve the problem in a way that covers many software layers, including interface and usability issues; and to support any step in the development cycle without great implementation effort, facilitating adaptation and refactoring of existing applications. This dissertation presents an Android library built to help developers provide offline functionality on their apps, while trying to solving these two challenges. To do that, the library, called OfflineManager, was built to be easily installed and utilized, and offers different ways to treat each call to the back-end, both in case of Internet connection missing, or in case of an unavailable server. It also offers feedback messages, and a point of interaction via pop-up. To evaluate the library, four evaluation methods were used: specialist opinion, implantation on a real project, comparative experiment with users, and heuristic evaluation. All four evaluations conducted showed results indication that the library attends its purpose and caters for the two challenges presented, being that the first two evaluations analyzed implementation and development aspects, while the last two analyzed interface and usability aspects. Evaluations showed that the library is easy to install, use and comprehend, that the treatments offered are sufficient and that it improves app usability in an offline scenario. Although, some threats to validity can be listed, indicating that there is room for improvement in the way they were conducted. Finally some improvements can be presented as future work in order to improve the library, expand the experiments taken, and to consolidate guidelines for the library utilization.

Cinema can be used for many purposes nowadays, such as: entertaining, educating and also as an important device able of spreading knowledge, provoking reflections on relevant themes, such as the water issue, its scarcity and the need for its conservation and preservation. In this context, the objective of the research was to analyze the influence of environmental cinema as a means of environmental perception and its sensitizing impact on individuals for water conservation. The exploratory research presents results obtained by primary data, involving the selection of volunteers; a pre-selection of films addressing the water theme to compose a list; the selection of four films from this list for the consideration of the participants; the characterization, description, interpretation and brief analysis of the films selected for the research; and the application of questionnaires, being a preliminary on perception with respect to water, and a conclusive about the sensitizing impact of the films. The secondary data of the research were obtained by means of a bibliographical survey and reading of the material on the theme water; environmental film; cinema and water; conservation and preservation of water; and environmental perception and awareness. The results obtained were positive for the use of cinema as a sensitizing instrument, awakening in the participants a greater reflection on the uses of water and its importance for the maintenance of life.

The present work presents a study carried out with a company in the field of civil construction, with the objective of performing an analysis of the requirements of the Brazilian program of quality and productivity in the work habitat linked to the program my home my life of the federal government and ISO 9001. The methodology of this study was initially to carry out research on the subject and other related where it provided as a basis for the elaboration of visits and data collection in relation to the application of the requirements of each management system, including internal audits, external audits and periodic inspections. A construction company was selected in the interior of the state of São Paulo, which participates in the program my house my life as a way of collecting the data to complete the results. Based on this information, it was possible to analyze improvements to the process and to better manage the requirements. Among the results found was that there is no difference between medium and small organizations, the maintenance of the management system is effective when the planning is accomplished, standardization is possible to be obtained when having a corporate management, having employees with functions exclusive to the management system is quite fundamental, among others.

The thesis presents a proposal of relational analysis of the brazilian diplomats. We used the theoretical framework of Pierre Bourdieu to analyze, therefore, the agents of the field of diplomats during the period of the governments of the former presidents Fernando Henrique Cardoso (FHC) and Luiz Inácio Lula da Silva (Lula), that is, between the years of 1995 and 2010. The chosen period points to the main objective of the work: to understand the dynamics of action of diplomats based on their relationship with the process of alternation between the two governments. As a research strategy, we focus our analysis on the "game" of the field related with the process of selection and training of new diplomats. This strategy led us to the “Rio Branco Institute” (Instituto Rio Branco - IRBr), an institution linked to the Ministry of Foreign Affairs (Ministério das Relações Exteriores – MRE, also known as “Itamaraty”), which has a monopoly on the selection and training of brazilian diplomats. We assume that the diplomats are agents of the field of diplomats; therefore, they do not constitute a homogeneous group as their actions and ways of thinking the field. They are agents that share the same habitus of the field, so they are in constant dispute for the symbolic domination of the actions that lead the field. However, as a requirement of the theoretical framework, this assumption was been tested during empirical research in the same way as our initial hypothesis: the dynamics of internal disputes in the field of diplomats presents an interference from external factor, important to understand its logic of operation, which is the action of the political field. This can be observed even in an internal "game" of the field that shows high degree of autonomy like the process of selection and formation of new diplomats. We did a prosopographic study of the field agents involved in the game described. We associate this study with Geometric Data Analysis (GDA) as statistical methodology, more specifically with one of its components, Multiple Correspondence Analysis (MCA). We seek to understand the relationship between the field of diplomats and other social fields beyond the political field, such as the field of power and the field of international relations, according to the research focus. We also discussed the notion of autonomy in the field of diplomats, in addition to proposing a critical analysis of the idea "Itamaraty insulation". This work seeks to contribute to the development of the sociology of elites (or of the ruling groups) and to the still new sociology of international relations.
