Cantos de bar: sociabilidades e boemia na cidade de Natal

The academic work Bar Corners: sociability and bohemia in the Natal City (1946-1960) has as objective the study of a representation of the literary bohemia in Natal in the second half of the 1940 s and 50 s, by means of analyses of the memory books and the chronicles of the newspapers A Ordem and A República. In order to have a better understanding concerning the subject, in the first chapter we try to show the transformations which have occurred in Natal and, consequently, within Natal sociability during the first half of the twentieth century. The bohemia, demonstrated in this dissertation as a way of sociability, expressed itself through the meetings in bars and the serenades. In the second chapter, the study conducted a mapping of the bohemian spaces (cafes, candy stores, bars and prostituition houses) and established the differences between these spaces. We ideated the spaces as the stage of interpersonal relations, as people went to these places in the attempt to participate of the conversation groups that were found there, choosing them according to their affinity and personal interests. The last chapter has the purpose of investigating the bohemia in Natal through the experience of the chronicler Newton Navarro, who used to roam the dark streets of Ribeira in search for open bars, extending bohemia until dawn. The intellectual activity was associated with his bohemian practices. As he frequented the marginal areas in Natal, Navarro wrote about them in the major newspapers of the city

Contando o passado, tecendo a saudade: a construção simbólica do engenho açucareiro em Jose Lins do Rego (1919-1943)

In this work I have searched the symbolical sense of a specific place. I have started from the theoretical assumption that places are social relations resulting from material and symbolical conditions developed in a certain time and by certain factors. In this sense, I have analyzed the symbolical aspect of sugar plantation from some literary works created by the writer José Lins do Rego from the state of Paraíba. I intend to analyze the symbolical dimension senses, values and images used by this writer to show the sugar plantation. Giving special attention to the works from the named cycle of sugar plantation , I have searched for the senses and meanings used in José Lins do Rego literary discourse to create a fictional sugar plantation, showing this place in a specific way. Based in cultural history, I have used several sources: literary works, prefaces of books, memory works, journalistic works, letters written by intellectual men and history books. My time of analysis is from 1919 the beginning of José Lins do Rego s intellectual activity - until 1943 publication of Fogo Morto, last literary work that I have analyzed. In symbolical terms, what is sugar plantation, this place that has totally touched José Lins do Regos life and literary work? That was the structural question that has determined the present research

Segmentação Fuzzy de Texturas e Vídeos

The segmentation of an image aims to subdivide it into constituent regions or objects that have some relevant semantic content. This subdivision can also be applied to videos. However, in these cases, the objects appear in various frames that compose the videos. The task of segmenting an image becomes more complex when they are composed of objects that are defined by textural features, where the color information alone is not a good descriptor of the image. Fuzzy Segmentation is a region-growing segmentation algorithm that uses affinity functions in order to assign to each element in an image a grade of membership for each object (between 0 and 1). This work presents a modification of the Fuzzy Segmentation algorithm, for the purpose of improving the temporal and spatial complexity. The algorithm was adapted to segmenting color videos, treating them as 3D volume. In order to perform segmentation in videos, conventional color model or a hybrid model obtained by a method for choosing the best channels were used. The Fuzzy Segmentation algorithm was also applied to texture segmentation by using adaptive affinity functions defined for each object texture. Two types of affinity functions were used, one defined using the normal (or Gaussian) probability distribution and the other using the Skew Divergence. This latter, a Kullback-Leibler Divergence variation, is a measure of the difference between two probability distributions. Finally, the algorithm was tested in somes videos and also in texture mosaic images composed by images of the Brodatz album

Contribuição ao estudo das redes complexas: extensão do modelo de afinidade

Neste trabalho, elaboramos e discutimos uma rede complexa sem escala, ou seja, uma rede cuja distribuição de conectividade segue uma lei de distribuição de potência. Nosso trabalho pode ser resumido da seguinte forma: Para efeito de didática vamos começar com redes aleatórias que estão relacionados com situações reais e artificiais, e depois comentar as redes livres de escala, como proposto por Barabási-Albert (BA). Depois disso, discutimos uma extensão deste modelo, onde Barabasi e Bianconi (BB) incluem a qualidade. Discutimos também o modelo de afinidade, ou seja, (Ver Almeida et al). Finalmente vamos mostrar o nosso modelo, uma extensão do modelo de afinidade dada por e apresentar os resultados correspondentes. Para realizar tal tarefa modificamos a regra de ligação preferencial do modelo de BB colocando um fator que apresenta o grau de probabilidade entre os sítios da rede. Esta quantidade é feita pela diferença entre a qualidade do novo sítio e a qualidade dos anteriores. Este novo parâmetro produz novos resultados interessantes: a distribuição que segue uma lei de especial de potência, expoente apropriado. A evolução temporal da conectividade do sítio também é calculada . Além disso, mostramos também, os resultados que foram obtidos, via simulação numérica, para o menor caminho médio e o coeficiente de agregação da rede gerada pelo nosso modelo, isto é, pelo modelo de afinidade.

Braquiópodes (Rhynchonelliformea, Bouchardioidea) neógenos da bacia de Pelotas (RS) e seu significado paleoambiental

The occurrence of brachiopods in Cenozoic rocks of the Pelotas Basin is known since 1862. In spite of that, detailed systematic and taphonomic studies are still missing. Investigations made a half century ago, have suggested that these brachiopods could belong to Bouchardia cf. zitteli, a species found in the San Julian Formation, Late Oligocene, Argentina. Our data suggest that those brachiopods may resemble Bouchardia transplatina. In the Uruguayan portion of the Pelotas Basin B. transplatina is known in rocks of the Camacho Formation, Miocene. In addition, small recrystallized shells of brachiopods were also recovered from three Petrobras boreholes (2PJ-1-RS, 2PN-1-RS, and 2GA-1-RS) from the Pelotas Basin. Brachiopods come from the interval of 130 to 150 meters within the Miocene Henryhowella evax Zone. Despite the degree of taphonomic modiication of those brachiopod shells they indubitably belong to Bouchardia sp. This is noteworthy for various reasons: 1- Bouchardia is a brachiopod with warm water afinities. Presently, extant members of this genus are unknown in latitudes up to 34[degree]S, with the main records at 23[degree]S. 2- Although occurring in depths down to 200 meters, the living member (Bouchardia rosea) of this genus is most abundant in shallow platformal, nutrient-rich waters. 3- The occurrence of Bouchardia in the Miocene of the Pelotas Basin indicates that, at least to the interval of Henryhowella evax Zone, warm waters of the Brazilian currents prevail. This interpretation is in strong accordance with other paleoeoceanographic and paleoclimatic data offered by various groups of co-occurring microfossils, such as ostracodes and foraminifers.

Trata-se de uma análise do consagrado conto Uma Rosa para Emily, de William Faulkner, voltada para alguns dos principais aspectos de sua estrutura. Após considerarmos o enredo, discutimos a construção das personagens, com destaque para a protagonista, fazendo um levantamento e comentários sobre possíveis fontes de inspiração, destacando, entre outras, aspectos da biografia da poeta Emily Dickinson, a ficção e a poesia de E. A. Poe, romances de Charles Dickens e Henry James, o conto de Sherwood Anderson e a poesia de William Blake, Emily Dickinson, Robert Browning e John Crowe Ransom, acrescentando paralelos com o conto Bartleby, o escrivão, de Herman Melville. Analisamos, então, o foco narrativo, os símbolos e o significado, ressaltando aqui o desenvolvimento temático da narrativa.

Notas sobre Siegfried Kracauer, Walter Benjamin e a Paris do Segundo Império: pontos de contato

Trata-se de mostrar a originalidade crítica de Siegfried Kracauer diante da experiência da modernidade estética e de discutir as afinidades estético-teóricas de Kracauer e Benjamim ao analisar a Paris da segunda metade do século XIX, o Segundo Império, em particular, como fenômeno originário da sociedade de massas, da indústria cultural e do entretenimento e, sobretudo, do nazi-fascismo. Kracauer durante seu exílio parisiense (1933-41) escreveu uma biografia da sociedade: Jacques Offenbach e a Paris de sua época (Jacques Offenbach und das Paris seiner Zeit). Obra inovadora pelo seu enfoque da história do presente e com pontos de contatos com a Obra das Passagens (Passagen-Werk) ou Paris capital do século XIX de Walter Benjamin.
