As tecnologias digitais tornaram-se uma importante infraestrutura para as nossas vidas nas mais diversas dimensões – cultural, social, politicas e econômicas. As formas de mediação digital têm alterado meios tradicionais e convencionais de organização de tempo e espaço. No entanto, contextualizar e situar narrativas e práticas de produção e análise de dados de rede – gerados em grande volume e a uma grande velocidade – têm sido grandes desafios para pesquisadores de todo o mundo. Lançado no fim de 2014, o livro Big data? Qualitative approaches to digital research (Emerald Books, 2014) oferece uma visão crítica sobre análises qualitativas de novos tipos de dados, plataformas e meios de comunicação, suas implicações para o futuro e como melhorar ativamente a pesquisa em relação a estes. Com autores especialistas das áreas de sociologia, ciência politica, cultura, comunicação, metodologia e administração, os organizadores do livro, Martin Hand e Sam Hillyard, denominam de pesquisa social digital todas as perspectivas qualitativas de diversas disciplinas, conceitos e orientações metodológicas e empíricas que atestem a integração e a diversificação das tecnologias digitais e de dados na vida social de hoje.

Due to the appreciation of family farming by the Brazilian Federal Government, the Technical Assistance and Rural Extension was induced to restructure and act in a more participative way, culminating in the National Policy of Technical Assistance and Rural Extension (PNATER), changing the profile of technology transfer and knowledge (diffusionism) for an action that uses participatory methodologies focused on exchange of knowledge between farmers and technicians. The process of discussion of the trends of ATER brought the New ATER , with the recognition of agroecology as the main guidance. This research aimed to analyze methods of public ATER developed by institutions of Rio Grande do Norte, under the guidance of New ATER. The research is qualitative. Secondary data were collected through documental research and literature. Primary data were collected through a set of interviews applied to representatives of public institutions ATER, namely EMATER-RN, Diaconia and AACC and representatives of organizations that receive public ATER. The research showed the difficulties of EMATER-RN in implementing of New ATER due to lack of infrastructure and low adherence of the new form of technical assistance and rural extension. It was shown also that the AACC and Diaconia act with ATER through projects with implementation deadlines set, often interrupting ATER while communities are still in need of assistance

At first moment we present a reflection about the history of theater and later a contextualization of didactic movements oriented to scenic arts. Through at the constant dialogue with authors of areas involving education, theatre, corporeality and music was possible analyzing, develop and criticize a education work under my responsibility involving fourteen classes. At the second moment will occur a critical self about the quality of theater classes his contents and methodologies. The technique will be at side of the emotion and together develop skills aimed at tracing paths for theater developed at a classroom of a especific private school in Natal-RN. At the third moment one class is chosen for analyze of the academic research and many experiments happen after this decision, initiated and sensitized through of the music with a significant look at the corporeality and prioritizing the theater as content in ninth grade - elementary school two. At the conclusion is possible see that learning is mutual and the theater can become life routine as well as the arts in general and when all arts will be regularized into the national educational system for public and private schools we will have more susceptible humans and more intellectual capacity

Produced water is characterized as one of the most common wastes generated during exploration and production of oil. This work aims to develop methodologies based on comparative statistical processes of hydrogeochemical analysis of production zones in order to minimize types of high-cost interventions to perform identification test fluids - TIF. For the study, 27 samples were collected from five different production zones were measured a total of 50 chemical species. After the chemical analysis was applied the statistical data, using the R Statistical Software, version 2.11.1. Statistical analysis was performed in three steps. In the first stage, the objective was to investigate the behavior of chemical species under study in each area of production through the descriptive graphical analysis. The second step was to identify a function that classify production zones from each sample, using discriminant analysis. In the training stage, the rate of correct classification function of discriminant analysis was 85.19%. The next stage of processing of the data used for Principal Component Analysis, by reducing the number of variables obtained from the linear combination of chemical species, try to improve the discriminant function obtained in the second stage and increase the discrimination power of the data, but the result was not satisfactory. In Profile Analysis curves were obtained for each production area, based on the characteristics of the chemical species present in each zone. With this study it was possible to develop a method using hydrochemistry and statistical analysis that can be used to distinguish the water produced in mature fields of oil, so that it is possible to identify the zone of production that is contributing to the excessive elevation of the water volume.

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Successive curricular changes that occurred in professional education altered pedagogical practices, and these practices being developed by means of integrating projects, at Centro Federal de Educação Tecnológica de Sergipe (CEFET-SE), between 2001 and 2003, originated some questions which became the study object of this thesis. We search for theoretical support mainly in GEPEM research (GEPEM/UFRN) works and practices in order to analyze elements that emerged from this pedagogical practice. To do so, we take as main reference the research of qualitative approach. We developed documents analysis, interviews, considering three aspects: the scenery where these changes took place, the conception and implementation of the Integrating Projects for what, we ask support in pedagogy of projects studies and principles of interdisciplinary, and contextualization as curriculum structuring elements. This research brought out some difficulties, conflicts and possible consensus in developing the methodological strategies for the Projects. In this process of coexistence of the traditional and the new, of an unavoidable distance between what was thought and what was effectively done, elements for a new pedagogical practice emerged. This could be noticed in terms of participative work, formative moments, teacher s autonomy related to the pedagogical work. A new door could be open to the possibilities of taking conscience of accepting the differences and oneself autoexperimentation. These are the possibilities that make men, not being mere information deposit, can dialog and transform, producing his existence by this means. In the present case, the existence of being teacher, the build himself in the time of possibilities

In Brazil the theme quality in public construction has been widely discussed in the early 1990s, with the creation of the Brazilian Program of Quality and Productivity for the Habitat (PBQP-H) which is strongly influenced by the wave of studies on issues of quality in the world, such as the ISO 9000. Over the years, other approaches have emerged and been consolidated, evolving from market and customer´s needs. An example is the Six Sigma methodology. This study aims to examine the Six Sigma, ISO 9000 and PBQP-H methodologies, noting the common elements, differences, gaps and how the methods are complementary, so that with the ongoing work, proposed initiatives can be developed to improve the quality that enables its application in public construction. Still aiming to optimize the deployment of the proposed initiatives, it was performed an analysis of ISO 9001 and PBPQ-H certifications in Brazil and in the state of Rio Grande do Norte, with respect to the construction industry and a case study to identify the factors that influence the adoption of initiatives to improve quality, and check if the selected construction company is prepared to implement the proposed initiatives. This research is characterized as exploratory and applied, with literature review and a case study. The data collection instrument was a questionnaire and the statistical analysis used a multidimensional scaling method. The conclusion is that the methodologies are compatible and complementary, and their integration could potentialize the goals set. It was identified that the state of Rio Grande do Norte has a few number of certifications in construction. Nine initiatives are proposed for implementation at construction companies. In the case study it was found that the studied company would be able to implement the suggestions proposed and the requirement for certification by clients and funding institutions influence the adoption of quality improvement initiatives. This result confirms the literature which states that top management support is crucial for the successful implementation of quality methodologies
