A capoeira e os mestres

The Capoeira considered as a manifestation of the Popular Culture - inheritance of African peoples - is a cultural and social practice present in Brazil since the colonial time. This study is dedicated to the Capoeira and its masters. We work the Capoeira as a social field through the theoretical perspective of the Sociology of Pierre Bourdieu. We try to apprehend the social construction of the master, the legitimacy of his knowledge, the disputes and the representations that they ve elaborated over the space which was redefined for material and symbolic changes that occurred with the Capoeira through the last decades. The operating notions of social field, habitus, capital and tradition had been pertinent to think the power games , the social relations and the symbolic plots in the Field of Capoeira. From the methodological standpoint, although the interviews with the masters and the direct observation have had a special place in the research, other strategies had been used: researches in newspapers, thematic magazines and periodic, musical compositions and academic works. The performance of the masters in the process of reinvention of traditions has redefined their social place in relation to the previous generations. These are perceived as social actors responsible for the maintenance, dynamicity, affirmation, spreading and expansion of the capoeirístic practice

Análise dos indicadores de qualidade versus taxa de abandono utilizando método de regressão múltipla para serviço de banda larga

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

Dinâmica da paisagem na Microbacia do Riacho Cajazeiras no semiárido potiguar

The semi-arid Northeast region are coming through changes since its formation causing changes in the landscape and increased degradation. The economic dynamics which was established at the Potiguar semiarid had for a long time settled in livestock, subsistence agriculture and cotton, however, these economies decline from the year 1970. Thus, the Potiguar spaces are undergoing by a process of space reordering marked by the growth of agricultural activities and the process of urbanization. In the Potiguar western region these changes weaken significantly transform the landscape. In these areas, the process of urbanization and agricultural activities have caused changes in the hinterland landscape changing the natural dynamics of the caatinga biome that has been subject to negative interference with the indiscriminate removal of vegetation. In this case, the specific study area of the watershed of Cajazeiras Creek located in the cities of Pau dos Ferros, Água Nova, Encanto and Rafael Fernandes, changes in the landscape has led to degradation and environmental fragility. From this perspective, the research objective is to assess the dynamics of the landscape of the watershed of Cajazeiras Creek, semiarid region of the state of Rio Grande do Norte, identifying the degrading factors, the most degraded areas and/or susceptible to degradation and environmental fragility. The research investigated the phenomena of light geosystems theory that emphasizes the integration of elements in shaping the landscape. During this reporting period, it was carried out exploratory and bibliographical research, and geoprocessing techniques to assess the social and environmental conditions of the researched area and its environmental fragility. To do so, first, it was made an multitemporal analisis on the basis of the years 1984, 1996 and 2009 demonstrating that the dynamics of use and land cover in the watershed of Cajazeiras Creek showed a significant change in the landscape, especially in the caatinga vegetation. This has been recovering in various areas of the watershed, especially in its upper course in the mountains of Bom Sera, in Encanto city. The analysis showed the need to develop policies and programs for the maintenance, restoration and preservation of the caatinga vegetation of the river network and of water bodies. In addition, it was identified the most degraded areas of the watershed, environmental fragility and potential emerging that take into account the landscape components such as climate, topography, geology, pedology, geomorphology and the use and occupation of the soil in an integrated manner. The results show that the landscape of the watershed has medium and high environmental fragility throughout its area, especially on the banks of the river network provided by the use and occupation of the soil in an inadequate way with the environmental conditions of the watershed

Associação da imunoexpressão das proteínas XRCC1, TFIIH E XPF com características clinicopatológicas e sobrevida em carcinoma epidermoide de língua oral

DNA repair systems, genes and proteins are essential for genome integrity maintenance, avoiding serious diseases such as cancer. Deregulation in the expression of those proteins has been associated with both the risk of development and evolution of various human cancers, including oral squamous cell carcinoma. The purpose of this study was to analyze the immunoreactivity of the DNA repair proteins XRCC1, THIIF and XPF in oral tongue squamous cell carcinoma (OTSCC) and to investigate its association with clinical and histopathological parameters, outcome and 5-year survival rate. Seventy-four cases of OTSCC were analyzed semi-quantitatively through immunohistochemistry. We observed that DNA repair proteins were highly expressed in parenchymal cells; however, we only observed a significant association between XRCC1 high expression and better clinical staging (p=0,02). Cox regression showed that tumor size (p<0,01), lymph node involvement (p=0,04), tumor stage (p=0,02) and depth of invasion> 4mm (p=0,05) were prognostic factors. The results of this experiment suggest that XRCC1, TFIIH and XPF participate in the tumorigenic process, however, their immunoexpression may not be used as an independent prognostic indicator for OTSCC.

Os operadores argumentativos como estratégia linguística e discursiva da argumentação na sentença judicial

We studied in this dissertation the argumentation in the court judgment, which goal was to identify, describe and explain the running of argumentative operators in the argumentative orientation of text and discourse built through the text of the judgment. We support our research in the constructs adopted for the ATD – (Textual Analysis of the Discourses) - Adam (2011), in the studies about the Aristotle’s Rhetoric (1959) and Perelman and Olbrechts-Tyteca (1996) and other works such as of the Alves (2005), Capez (2008), Charaudeau (2012), Keller and Bastos (2015), Koch (2009; 2011), Rodrigues, Silva Neto and Passeggi (2010), Trubilhano and Henriques (2013). In a methodological way, we made use of deductive-inductive method, because we analyzed the argumentation in an "unknown" text - particular case - based on a theory already known (about language, text and argumentation). About the nature and objectives, our search was characterized as qualitatively and as an explanatory and descriptive investigation, with technical procedures of documental collection of Bibliographic Search. As corpus, we use a court judgment of character condemnatory, issued on September 10, 2014 and taken from the online site of the Federal Court of Rio Grande do Norte (JFRN). The results revealed that the argumentative operators exercised decisive roles in the organization of argumentative strategies of the text and the speech , guiding the announcer to the Desired conclusion by the enunciator. It was also possible to conclude that the use of argumentative operators allowed syllogistic constructions in the form of presentation of the arguments and in the construction of argumentation. In addition, operators like "but", "until", "already", "although" etc. helped to identify in the data's analysis the point of view (PoV) of the enunciator, the expectation break about the previous enunciate and / or the value scale given to the argument. Finally, with the use of argumentative operators the enunciator introduced arguments able to demonstrate/justify a thesis and refute an opposing thesis towards a conclusion sought by the own enunciator.
