(Por) entre pedra e tela: a construção de uma memória republicana (Natal - 1906-1919)

This work, from a perspective that thinks the space as a historical category, and especially as a relationship which stresses the role of objects, proposes an analysis of the construction of a Republican memory in the city of Natal in the early twentieth century. This research will focus mainly on two objects: the obelisk opened in 1917, and the Andre de Albuquerque Square on the occasion of the celebration of Frei Miguelinho´s death centenary and the paint Julgamento de Frei Miguelinho ordered by the State Government to the painter Antonio Parreiras, picture that was in the Salão Nobre do Palácio do Poder Executivo of that time. In a geral way this work intend to analyse the construction of this memory as well as the role of these objects in this process. To achieve that, we propose to trace ways and networks to follow the possible associations(between people, events, images, discourses, objects, institutios etc.) in the constitution of mutual belongings. Thus, our procedure was to follow these objects through the pathways in which they became possible, so that in the end we could defend the idea that they are active participants of the process that establish them.

Adolescentes preocupadas em conquistar um corpo magro: Um estudo sobre discursos produzidos em diários eletrônicos

The concern about a good physical condition is heavily present nowadays, in documentary films about health and in the media, and it is also expressed through the outstanding growth of physical academies, beauty institutes and aesthetic medicine and all kind of aesthetic surgeries. In the western world the body wave is a significant trend, characterized by the great investments in body image. However, what is overlooked is the fact that in parallel trend grows the number of teenagers, especially females, with all kind of problems related to their body image. As adolescence is a moment of transformations, teenagers tend to be more aware of their body image and often neglect food ingestion and try to build their bodies following the images they have from top models and movie stars. The low self-esteem accompanying this sort of experience is an additional problem. Therefore the research aim to analyze discourses regarding the body image produced in world wide web diaries (blogs). The blogs selection was made through the site www.blogs.com.br, which is considered the widest guide of electronic diaries in Brazil. We looked after blogs including the keyword body and from adolescents aged 10 to 19, who showed concern about a slim body. Three blogs were chosen, considering the example criteria. Discourse analysis shows that these teenagers feel unsatisfied with their bodies, searching by all means the thinness presented as a aesthetic paradigm in western societies which often implies neglecting their own health, using appetite inhibitor drugs, restricting or totally abstaining food ingestion for long periods of time, or provoking themselves vomits after ingesting food. These behaviors, together with intense fear of gaining weight, can be characterized as alimentary disorders, related to the body image. As they usually hide this sort of behaviors from family and friends who do not share this concern, the blogs seem to be an easy tool for adolescents to find peers with whom to share common values and ideas and reaffirm their identities and virtual sense of community

Aplicação da modelagem estrutural computacional direta na análise da geometria de falhas: exemplo da falha de Baixa Grande (Bacia Potiguar - NE do Brasil)

The Baixa grande fault is located on the edge of the S-SW Potiguar Rift. It limits the south part of Umbuzeiro Graben and the Apodi Graben. Although a number of studies have associated the complex deformation styles in the hanging wall of the Baixa Grande Fault with geometry and displacement variations, none have applied the modern computational techniques such as geometrical and kinematic validations to address this problem. This work proposes a geometric analysis of the Baixa Fault using seismic interpretation. The interpretation was made on 3D seismic data of the Baixa Grande fault using the software OpendTect (dGB Earth Sciences). It was also used direct structural modeling, such as Analog Direct Modeling know as Folding Vectors and, 2D and 3D Direct Computational Modeling. The Folding Vectors Modeling presented great similarity with the conventional structural seismic interpretations of the Baixa Grande Fault, thus, the conventional interpretation was validated geometrically. The 2D direct computational modeling was made on some sections of the 3D data of the Baixa Grande Fault on software Move (Midland Valley Ltd) using the horizon modeling tool. The modeling confirms the influence of fault geometry on the hanging wall. The Baixa Grande Fault ramp-flat-ramp geometry generates synform on the concave segments of the fault and antiform in the convex segments. On the fault region that does not have segments angle change, the beds are dislocated without deformation, and on the listric faults occur rollover. On the direct 3D computational modeling, structural attributes were obtained as horizons on the hanging wall of the main fault, after the simulation of several levels of deformation along the fault. The occurrence of structures that indicates shortening in this modeling, also indicates that the antiforms on the Baixa Grande Fault were influenced by fault geometry

Análise de estabilidade de falésias na zona costeira de Baía Formosa - RN

The natural and anthropogenic changes that are occurring at the coastal zone around the world represent the greatest problem to society in this century. This problem becomes more evident due to high density of coastal cities, to growing tourist-estate speculation of those areas and to climate change that tend to trigger and accelerate the erosive processes that operating in the littoral. In this context, it‟s possible perceive ever more a significant increase of problems associated to the coastal erosion and retreat of cliffs in the state of Rio Grande do Norte, where this study area of this search is located. The area is located in the coastal zone of the city of Baía Formosa/RN, in south-eastern coast of Rio Grande do Norte, and has a extension of about 1200 meters along the Porto beach. The main objective of this study is to analyze the stability of these cliffs in this region. Through field investigations, testings and computational analysis using the Finite Element Method and Equilibrium Limit Methods. The area was divided into four sections, and were applied checklists, and also realized characterization tests and direct shear tests with materials obtained along these sections. In this manner, it was found that the segments of cliff in this coastal zone have heights around 4 meters to 14 meters and inclinations of approximately 40° to 90°.However the constituents soils of the cliffs were classified, in general terms in accordance to Unified Soil Classification System (USCS), as clayey sands or silty sands, clays of low plasticity, clayey gravels and poorly graduaded sands. The most variegated and clayey soils belong to base of the cliff. The stability analysis showed that the safety factors ranged in section 01, from 1.92 to 4.93, in the section 02, from 1.00 to 1.43, in the section 03, from 1.36 to 1.75 , and section 04, from 1.00 to 3.64. Thus, the sections 02 and 03 were considered more unstable. However, the section 03 can be considered as the most critical section due to the absence of coastal protection structures and the narrow strip of beach.

Os discursos sobre a educomunicação na rádio escolar: um estudo etnográfico e m uma escola pública

This research analyzes the discursive construction of Educommunication, from a training course of educommunicators, with teachers and students of school Profº Francisco Ivo Cavalcanti, state public school, geographically located in the city of Natal / RN, studying the constitution of the meanings that educommunication practice in School Radio acquires for trainers and course participants (teachers and students). The socio-historical context in which this research is based corresponds to the new social reality, mediated by information and communication Technologies. These technologies drive the educational institution to train students in the use of different languages that permeate society. But to do so, you must have also enabled teachers to work Communication technology to meet the aspirations of young people and adults who are part of the educational community. The objectives are to identify the conditions of discursive production around the educommunication practice in Radio School, examine the discursive construction of instructors and course participants in Educommunication and its dialogical brands, and see how the course participants relate to their educommunicative practice in the educational contexts, attributing meaning to the place of teachers and students. Therefore, this research uses ethnography applied to the school context as a methodological option, Pecheuxtian Discourse Analysis, the principles of Educommunication, the reflections of Paulo Freire and the concepts of Dialogism in Bakhtin as theoretical contributions. We adopted three areas of knowledge: Language, Communication and Education, in order to produce an analysis committed to the aspects that involve the use of radio in the school environment to promote an educommunicative practice. With this research we have built a web of meanings about the school that we are forming or we want to form in the XXI century, because we used the discourses of teachers and students immersed in new knowledge and practices in order to propel them to be subjects of communication in educational environment for a qualitative transformation of being and doing in school.

Indicador de vulnerabilidade agropecuária a extremos climáticos para o nordeste do Brasil

The effects of climate change on human societies have become the focus of many researchers for their research. Understanding weather patterns (circulation of the atmosphere, precipitation, temperature) is essences for predicting extreme weather, but analyze how these extreme events act in our society and look for ways to reduce the impact caused by these events is the great challenge. Using a concept very in the humanities and social sciences to understand these impacts and the adaptation of the society's vulnerability. The objective of this work is to develop and apply a methodology for evaluating fining scale and quantify the vulnerability of the Brazilian Northeast to climatic extremes, developing a methodology that combines aspects of vulnerability to drought, as well as socioeconomic and climatic indicators used to assess exposure, ability to adaptation and the sensitivity of geographical microregions of the region. The assessment of the susceptibility or degree of exposure to risk is the regional using the SPI (Standardized Precipitation Index) by the degree of magnitude dried (MD), the rate of precipitation such as PCD (Precipitation Concentration Degree) and PCP (Precipitation Period Concentration) helped characterize and regional climatology, these indices showed satisfactory results in the pilot study of Rio Grande do Norte to assess the degree of exposure to drought. Regarding sensitivity agricultural / livestock multivariate statistical technique to factor analysis showed acceptable results for the proposed model using data for the period 1990-1999 (P1). The application of the analysis of vulnerability considering the adaptive capacity, as the adaptive disability have almost similar results with much of the region's vulnerability to extreme south of Bahia state as a part of the semiarid region has a degree of vulnerability among moderate and mean

Análise de superfícies seletivas em frequência com geometria multifractal

Frequency Selective surfaces are increasingly common structures in telecommunication systems due to their geometric and electromagnetic advantages. As a matter of fact, the frequency selective surfaces with fractal geometry type would allow an even bigger reduction of the electrical length which provided greater flexibility in the design of these structures. In this work, we investigated the use of multifractal geometry in frequency selective surfaces. Three structures with different multifractal geometries have been proposed and analyzed. The first structure allowed the design of multiband structures with greater flexibility in controlling the resonant frequencies and bandwidth. The second structure provided a bandwidth increase even with the rising of the fractal level. The third structure showed response with angle stability, dual polarization and provided room for a bandwidth increase with the rising of the structural multifractality. Furthermore, the proposed structures increased the degree of freedom in the multiband designs because they have multiple resonant frequencies ratios between adjacent bands and are easy to deploy. The validation of the proposed structures was initially verified through simulations in Ansoft Designer software and then the structures were constructed and the experimental results obtained

Análise de usabilidade de livro digital na EaD: aplicação da avaliação heurística proposta por Pechansky

Nowadays the Distance Learning (DL) is in its fifth generation and New Information and Communication Technologies (NICT) mediate it. In this technological context it is then called Distance e-Learning (DeL). DeL has also in the e-books a potential interactive tool to the collaborative learning. So, this study was accomplished with the purpose of analyzing the e-books developed by SEDIS – Secretaria de Educação a Distância (Department of Distance Learning). This study was performed in two phases: Firstly it was done an exploratory study to check out the reading and the handling of digital e-learning material available to the student-users. These e-books are obtainable on SEDIS Moodle platform. Secondly, it was performed some analysis of an e-book sample by means of the heuristic evaluation. This research aims both to identify potential problems and give some suggestions to solve them. At last it is presented a final report with diagnosis and suggestions for a more applicable design in order to optimize the e-book by means of the distance e-learning usability guidelines

Análise textual das representações discursivas no discurso político brasileiro: o discurso da primeira posse da presidenta Dilma Rousseff (1°/01/2011)

Cette recherche décrit la représentation discursive que la présidente Dilma Rousseff fait de soi-même, dans son discours devant le Congrès National, lors de la journée d’investiture, le 1/1/2011. Notre travail se situe dans le domaine théorique et méthodologique de la linguistique du texte et, plus spécialement, dans la perspective de l’Analyse Textuelle des Discours – ATD (ADAM, 2011 [2008a]), qui se définit comme « une théorie de la production co(n)textuelle de sens qui doit se fonder sur l’analyse de textes concrets ». Elle nous fournit la notion théorique et analytique de « représentation discursive », qui se focalise sur la dimension sémantique du texte. Nous nous appuyons, aussi, sur des travaux récents sur les représentations discursives, réalisés dans la recherche brésilienne sur l’ATD (RODRIGUES, PASSEGGI, SILVA NETO, 2010, 2012; RAMOS, 2011; OLIVEIRA, 2013; QUEIROZ, 2013; ZAMBLANO-OLIVEIRA, PASSEGGI, 2013). Les principales opérations sémantiques de construction de la représentation discursive utilisées dans notre travail sont la Référenciation et la Prédication. L’approche méthodologique est, en même temps, qualitative et quantitative, priorisant l’identification des occurrences, ainsi que la description détaillée de leurs valeurs sémantiques et textuelles. Les résultats de la recherche sont de trois ordres : méthodologique, théorique et descriptif-interprétatif. Méthodologique : nous proposons une approche que nous désignons comme « marquage textuel » (ou « mappage textuel ») qui permet de marquer (étiqueter) les valeurs sémantiques des formes linguistiques, permettant leur identification dans le flux textuel, c.-à-d., dans la dimension séquentiellecompositionnelle du texte. Théorique : nous introduisons la notion de « domaines de la représentation discursive » qui organisent et articulent les différents éléments qui composent la représentation discursive de la présidente. Quant aux résultats descriptifsinterprétatifs du discours de l’investiture, ils indiquent que la représentation discursive de la présidente se configure au moyen de différents domaines conceptuels, explicités par les référenciations et les prédications. Ils mettent en relief les désignations et les actions / états, aussi bien de la femme – domaine du genre – que de la présidente – domaine du rôle politique et institutionnel. La présidente se représente explicitement et avec emphase comme l’agent responsable par les actions exprimées par les prédications verbales (verbes d’action), consciente de l’importance de son rôle politique et social. Les prédications nominales signalent clairement une représentation discursive qui englobe les domaines conceptuels politique, moral, éthique, comportemental et émotionnel (forte, accueillante, pionnière, consolidatrice, infatigable, humble, engagée, démocrate, victorieuse et courageuse). Le discours d’investiture réalise, donc, des désignations positives de la présidente, lesquelles se situent dans un temps présent et prospectif – avec des perspectives de futur – comme leader politique du Brésil, avec une participation active dans la transformation du pays, tenant compte aussi de son histoire de vie, sa biographie de luttes. Ainsi, la description empirique et l’interprétation de ce discours particulier contribue à l’analyse textuelle des représentations discursives dans le discours politique brésilien contemporain. Elle soulève, aussi, des questions théoriques et méthodologiques qui nous semblent pertinentes pour le développement de cette aproche.

Resumo de dissertações e teses: a estrutura composicional à luz da Análise Textual dos Discursos

This doctoral dissertationproposes the description, interpretation and analysis of the compositional structure of thesis and dissertation abstracts, with regard to the linguistic mechanisms that evidence text zones of different typological sequences, such as those of the text plan. Along these lines, the research problem was developed from the notion of compositional structure (sequences and text plans), as one of the levels or plans of text analysis, according to the theoretical framework proposed by Jean-Michel Adam (2011a). The main objective of this study was to recognize how the compositional structure, of thesis and dissertation abstracts, is achieved, with respect to text units and the global organization of this text category. The hypothesis posed in this research posits that specific informational text composition categories of abstracts are necessary to process the representation of the original text and the way in which it makes its meaning. Subsequently, this study is based on the theoretical and methodological framework of Text Linguistics (TL) and, above all, Textual Discourse Analysis (TDA), as we endeavor to understand the organizational structure of abstracts from both a linguistic and textual perspective. This structure involves the text plan of abstracts, with respect to their communicative purpose, i.e, the sharing of scientific information in its standard textual form. Thus, the development of this study, from a theoretical and methodological perspective, is based on the theoretical and descriptive premises from TDA (ADAM, 2011a, 2012; PASSEGGI et al., 2010), and also from TL (BEAUGRANDE; DRESSLER, (2012 [1981]); COSERIU; LAMAS (2010); MARCUSCHI, 2009 [1983]; FÁVERO; KOCH, 1994;KOCH, 2006; BENTES, 2004; BENTES; LEITE, 2010), within the field of text studies. The methodology of this study relies on empirical, documental research, which is qualitative, and adopts a descriptive and interpretive approach. From the empirical perspective, our objective is to understand the problems pertaining to the textual composition of abstracts, aiming to elucidate them in light of the theoretical and methodological framework previously mentioned. The corpus of the analysis is comprised of seven abstracts designated for systematic data collection. These texts, written between 2004 and 2011,were selected from Master’s theses and Doctoral dissertations in their electronic version, from the graduate program at the Federal University of Rio Grande do Norte. A thorough review of the literature reveals a clear fluctuation in the terminology of the concept, ‘abstract’. The results of the analysis revealed that the abstracts, which comprise the corpus of analysis in this study, in general, present typological heterogeneity, while the text plan remains fixed. Finally, the new knowledge gained in this research contributes both to the understanding of the compositional structure of abstracts as well as their production.

Análise de sedimentos associados à atividade de perfuração na plataforma continental externa, Bacia Potiguar - Brasil

This study was developed in an area located on the outer shelf in the Potiguar Basin, Brazilian equatorial margin; this tropical shelf represents a modern, highly dynamic mixed carbonate-siliciclastic system. Field sampling was carried out during 3 cruises surrounding a shallow-water exploratory well to compare sediment properties of the seafloor, including grainsize, texture, mineral composition, carbonate content, and organic matter. Cruise 1 (C1) was carried prior to drilling, while Cruise 2(C2) and 3 (C3) respectivelly 3 and 12 months after drilling. The sample grid used had 16 stations located along 4 radials from 50 m the well up to a distance of 500 m. Sediments were analyzed in the first 0-2 cm, and 0-10 cm layers. The results show that sedimentary cover around the well is poor to very poorly sorted, with the particle size predominantly in the medium to coarse sand fraction, followed by gravel and mud. The content of calcium carbonate is greater than 96%, associated to bioclastic sediments, and the content of organic matter is less than 12%. Only minor sedimentological variations occured in the area affected by drilling operations. Mainly observed during the second cruise, in terms of a change in grain size distribution associated to an increase in siliciclastic content, This impact occurred in the most surficial sediment (0-2 cm), in the radial closest to the well (50 m), and could suggest the effects of drilling. However, in the third cruise, one year after drilling, the sediments return to show the same characteristics as in the first cruise. These results show no significant sedimentological variations due to drilling activity, and indicate that ocean dynamics in this area was high enough to recover the environment original characteristics.

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.
