Made available in DSpace on 2015-09-25T12:23:36Z (GMT). No. of bitstreams: 1 Claudeci_PDF.pdf: 1959106 bytes, checksum: b90c920d5007c594cff6116bbfecf661 (MD5) Previous issue date: 2009-06-05 / Inês Caetano de Oliveira (Marinês) initiated her career as a forró singer in the year of 1957 and gained space in the national market as the Queen of Xaxado , image that links her to the Northeast Brazilian culture. On this research we consider the lyrics of the songs in her repertoire as literature, from an extended concept, attributed by the Cultural Studies, which cover several diverse cultural productions, as chained forms of meaning. In this manner we formulated the following researche question: How is the Northeast of Brazil represented in the lyrics in the songs of the singer Marinês? Due to this, our objectives were: To do a research on the phonographic production of the singer between the years of 1957 to 2007; analyze how the Northeast population and the Northeast are represented in the lyrics of theses songs; analyze the contribution and the trajectory of the singer to the Northeast popular culture. For the composition of the corpus to be analyzed in this project, we selected 22 songs that were recorded the most by the artist in the 50 years of her career, that appear at least twice in different albums and addresses the Northeast as a theme. This choice had as base a digital database elaborated for the development of this research, that identifies the titles of the song and the names of their composers, how many times they were recorded by the singer, in which album and year of the production. We did the analyses of the lyrics based on the themes that were recurrent topics about the region: Northeast identity, drought, rain, cultural practices, the relationship with other living beings and nature. During the research, we verified that the lyrics of her songs demonstrate important aspects for the production of knowledge about the region and the Northeast culture: religion, traditional customs and a sense of being . We conclude stating that the songs in Marinês repertoire configure a construction of regional identity, based in tradition, through representations valued positively, revealing the pride in being from the northeast. / Inês Caetano de Oliveira (Marinês) iniciou sua carreira como cantora de forró no ano de 1957 e ganhou espaço no mercado nacional como a Rainha do Xaxado , imagem que marca o seu vínculo com a cultura nordestina. Neste trabalho, consideramos as letras das canções de seu repertório como literatura, dentro de uma concepção ampliada, tributária dos Estudos Culturais, que abarca produções culturais diversas, enquanto formas correntes de significação. Formulamos, assim, a seguinte questão de pesquisa: Como o Nordeste é representado nas letras das músicas da cantora Marinês? Por sua vez, nossos objetivos foram: fazer um levantamento da produção fonográfica da cantora entre os anos de 1957 e 2007; analisar como a região Nordeste e os nordestinos são representados nas letras das canções; analisar a contribuição e trajetória da cantora para a cultura popular nordestina. Para a composição do corpus a ser analisado no trabalho, selecionamos 22 músicas, dentre as mais gravadas pela artista no período dos 50 anos de sua carreira, que aparecem no mínimo duas vezes em discos diferentes e abordam o Nordeste como tema. Essa escolha teve como base um banco de dados digitalizado, elaborado para o desenvolvimento desta pesquisa, que identifica os títulos das músicas e os nomes de seus compositores, quantas vezes foram gravadas pela cantora, em qual disco e o ano de sua produção. Realizamos as análises das letras a partir dos temas recorrentes nos discursos sobre a região: identidade nordestina, estiagem, chuva, práticas culturais, relações entre os seres vivos e a natureza. No decorrer da pesquisa, verificamos que as letras das suas músicas mostram aspectos de importância para a produção de conhecimento sobre a região e a cultura nordestina: religião, costumes, tradições e o sentimento de lugar . Concluímos mostrando que as canções do repertório de Marinês configuram uma construção de identidade regional com base na tradição, através de representações valoradas positivamente, revelando o orgulho em ser nordestino.

Os Sertões de Euclides da Cunha e \"os sertões\" de Caio Prado Júnior: um universo entre história e literatura / Rebellion in the backlands by Euclides da Cunha and the Caio Prado Junior\'s \"backlands\": a universe between history and literature

Talita Yosioka Collacio 03 May 2016 (has links)
Neste trabalho são analisadas as relações entre História e Literatura a partir da noção de \"sertão\" nas obras de Euclides da Cunha e de Caio Prado Júnior. Discutimos as diferenças e semelhanças entre as disciplinas História e Literatura, partindo-se de seus métodos e narrativas. Em seguida, abordamos os escritos de Euclides da Cunha, nos quais os relatos dos viajantes naturalistas desempenham papel fundamental no estabelecimento do \"consórcio da ciência e da arte\" e na definição de \"sertão\", local isolado e despovoado. Os textos de Caio Prado Júnior também revelam a importância dos relatos desses viajantes na elaboração de uma interpretação materialista da história do Brasil, embora sua definição de \"sertão\" compreenda apenas o semiárido nordestino. Em ambas as análises, o sertanejo se destaca como elemento formador da nossa nacionalidade. Para Euclides da Cunha, por suas características étnico-raciais e, para Caio Prado Júnior, pelas condições socioeconômicas. / This article analyses the relationship between History and Literature from the notion of \"backwoods\" concept present in Euclides da Cunha and Caio Prado Júnior\'s works. The differences and similarities between the History and the Literature disciplines are discussed, starting with their methods and narratives. We address Euclides da Cunha\'s writings in which the reports of travelling naturalists play a key role in establishing the \"consortium of sciences and arts\" and in defining \"backwoods\" as an isolated and depopulated place. Caio Prado Júnior\'s texts also reveal the importance of these travellers\' reports in developing a materialist interpretation of the Brazilian History, although his definition of \"backwoods\" embraces only the semi-arid region of Northeastern Brazil. In both analyses, the rural work stands out as an important element to compose our nationality. According to Euclides da Cunha, it is so due to this character\'s ethnic and racial attributes. On the other hand, Caio Prado Júnior considers the socioeconomic conditions.

De centro a periferia: as transformações sofridas pelo Nordeste Paulista na chegada do café (1873 - 1905) / Centrality becames periphery: the arrival of the coffee economy in Northeast of São Paulo (1873 - 1905)

Rafael Giorgi Costa 02 May 2016 (has links)
Este estudo teve como objetivo avaliar a influência do mercado externo (agroexportação) no desenvolvimento do mercado interno de abastecimento, durante o século XIX, no Estado de São Paulo. Primeiramente, foram coletados e sistematizados os dados referentes à composição social e à produção de alimentos para os anos de 1836 e 1854, revelando regiões da Província de São Paulo onde se concentravam diferentes circuitos do mercado interno de abastecimento, não só no que se refere ao artigo produzido como também à quantidade e ao valor gerado. Com base nos resultados, realizou-se pesquisa bibliográfica específica para cada região, o que permitiu a caracterização mais completa das formações sociais em questão e, com isso, a definição de dois setores bem distintos do mercado interno: pecuário e alimentício. O mercado pecuário, concentrado no Nordeste Paulista e nos caminhos do sul, possuía circuitos mais longos e enriquecedores do que o mercado de gêneros alimentícios, por sua vez majoritariamente localizado em meio às zonas agroexportadoras de café e açúcar, fator que limitava seu desenvolvimento. O Nordeste Paulista, mais especificamente o município de Franca, foi responsável por articular o Brasil central pecuário (Goiás, Mato Grosso e Triângulo Mineiro) com a faixa litorânea centro-sul (Rio de Janeiro e São Paulo), constituindo-se como importante centro de cria e (re)engorda. Operou nessa centralidade uma elite composta principalmente de fazendeiros chefes-de-parentelas, cuja reprodução como classe dominante envolvia sua inserção em cargos políticos e militares, a propriedade da terra e, consequentemente, o domínio sobre grande contingente populacional, incluindo agregados, escravos, compadres e parentes. A fim de avaliar se essa centralidade do mercado interno resistiu ao avanço cafeeiro que atingiu a região na década de 1880, questão ainda em aberto na historiografia, procurou-se pela presença das parentelas e suas linhagens nas listas dos maiores fazendeiros do período de transição. Revelou-se que a elite não só se inseriu como foi protagonista da economia cafeeira na região nas décadas de 1880 e 1890. No entanto, já na virada do século, todo o Estado de São Paulo sofreria com uma forte crise na economia cafeeira, demonstrando a fragilidade e suscetibilidade do mercado externo. Os dados da produção cafeeira do ano de 1905 apontam para a baixa relevância de Franca e Batatais no universo da agroexportação, enquanto os números da produção de gado desse mesmo ano indicam o deslocamento do eixo principal de articulação pecuária para oeste, mais precisamente para os municípios de Jaboticabal e Barretos, que assumiram a primazia no setor. Conclui-se que a aproximação da agroexportação impôs a reestruturação do mercado interno para áreas contíguas, devido ao grande desvio de investimentos por parte daquela elite pecuária para a economia cafeeira, o que revelou, em última instância, a dificuldade de ancoragem da produção endógena no espaço quando seu território se mostra atrativo para o estabelecimento da agroexportação. / This study aimed to evaluate the influence of the external market (agricultural exports) in the development of the internal market during the nineteenth century, in the State of São Paulo. Data about the social composition and food production for the years 1836 and 1854 were collected and systematized, revealing regions which focused different sectors of the domestic market supply. Based on the results, specific literature was consulted for each region, allowing a complete characterization of the different sectors of the internal Market: livestock and food. The livestock market, located in the Northeast of São Paulo and in the southern ways, had longer and more enriching circuits comparing to the foodstuff market, in turn mostly located in the agro-exporting region of coffee and sugar. Specifically the city of Franca, was responsible for articulating the livestock central Brazil (Goiás, Mato Grosso and Triângulo Mineiro) to the south-central coastal region (Rio de Janeiro and São Paulo), constituting an important center on (re)fattening cattle. This centrality was operated by an elite composed mainly of farmers, whose reproduction involved their insertion in political and military positions, land ownership and consequently the domain of large populations. In order to assess whether the centrality of the internal market resisted the coffee advance that hit the region in the 1880s, an issue still open in historiography, this research sought by the presence of those farmers and their lines in the population lists for the transitional period. It was revealed that the elite entered in the world of agricultural exports, but in the end of the nineteenth century a huge crisis in the coffee economy, showing the fragility of external Market. Data of coffee production in 1905 points to the low relevance of Franca and Batatais in the world of agricultural exports, while livestock production indicate the displacement of the main shaft of livestock to the West, specifically for the cities of Jaboticabal and Barretos. Concluding, the approach of agricultural exports imposed the restructuring of the internal market for contiguous areas, because of the diversion of investments by that livestock elite for the coffee economy, which proved ultimately, the difficulty of anchoring the endogenous production in space when its territory shown attractive for the establishment of agro-export.

“Mere Supplicants at the Gate”: Northeast Tennessee Politics in the Antebellum Era

Early, O.J. 01 May 2016 (has links)
Antebellum political historians have long studied the era between Andrew Jackson’s election and the secession crisis through the colored knowledge of the Civil War. This project is an effort to reverse that trend. It explores northeast Tennessee’s political culture from the late 1830s through the start of the Civil War. It reveals that the Second American Party System, a wave of new enfranchised voters, and the area’s demographics mixed together to lay a foundation for the aggressive and populist political style that permeated the region from the 1830s through the 1850s. At the heart of these issues was the transition of power from East Tennessee to Middle Tennessee. As a way to analyze the region’s political culture, I look specifically at Democrats Andrew Johnson and Landon Carter Haynes and Whigs William Brownlow and Thomas Nelson.

Comparison of Microbial Water Quality Parameters of Four Geographically Similar Creeks in Northeast Tennessee

Hall, Kimberlee K., Gallagher, L. K., Evanshen, Brian G., Maier, Kurt J., Scheuerman, Phillip R. 01 January 2006 (has links)
Four creeks within the Watauga River watershed in Northeast Tennessee are routinely monitored for water quality assessments. To identify sources and monitor remediation, Sinking Creek, Cash Hollow Creek, Buffalo Creek and Boones Creek are monitored for chemical and microbial parameters. These parameters include phosphates, nitrates, BOD and fecal coliforms. Sinking Creek is a tributary of the Watauga River with 10 miles of impaired water. Cash Hollow Creek enters the Watauga River at river mile 11.4 with 3.4 miles of impaired water. Boones Creek contains 18.6 impaired miles while the status of water quality in Buffalo Creek is not yet determined. Agricultural input is a major source of pollution for Sinking and Boones Creek. Cash Hollow Creek is impacted by a combination of sources of which urban runoff is the largest due to storm sewers and land development. Boones, Cash Hollow and Sinking Creeks are considered impaired and are on the state’s 303(d) list due to pathogen loading but only Sinking and Cash Hollow Creek have TMDLs. The seasonal and spatial patterns are more obvious for microbial than for chemical parameters. From 2002 - 2005, 14 stations on Sinking Creek were sampled quarterly. Fecal coliforms were elevated and always greater than 200 CFU/100ml for stations 1 – 5. Due to agricultural land use adjacent to stations 1 – 4, this would be expected. There was also a seasonal trend with higher concentrations found in the fall and spring. Cash Hollow Creek’s 9 stations were sampled monthly from 2002 - 2005. Although very high fecal coliforms concentrations were found, there were no obvious patterns. The 12 stations on Buffalo Creek were sampled quarterly from June 2004 to June 2005. Fecal coliform concentrations were high at station 8, which is adjacent to agricultural land. Boones Creek was sampled monthly from March 2005 to present and no obvious trends have been noted. The objective of this research is to compare patterns in these geographically similar creeks to identify any common patterns associated with various pollution sources. We will discuss the preliminary results and conclusions about the usefulness of these data to accomplish this objective.

Sequence Stratigraphy, Chemostratigraphy, and Biostratigraphy of Lower Ordovician units in Northeastern and Western Central Utah: Regional Implications

Davis, Colter R. 01 May 2017 (has links)
The Lower to Middle Ordovician Garden City Formation and Pogonip Group are coeval successions of mixed carbonate and siliciclastic rocks deposited under normal marine conditions on a shallow carbonate ramp on the western margin of Laurentia. The Garden City Formation was deposited in the Northern Utah Basin and the Pogonip Group was deposited in the Ibex Basin. These two basins experienced different rates of thermal subsidence following Neoproterozoic rifting along the western margin of Laurentia resulting in significant thickness differences between rock units and varying lithologic expressions of eustatic change. This study provides a unique opportunity to examine the lithologic, geochemical, and paleontological responses to eustatic oscillations of two coeval sedimentary basins in Utah that formed under different tectonic settings and subsidence rates. The Garden City Formation is composed of fourteen lithotypes and the Pogonip Group is composed of eleven lithotypes. These lithotypes mainly represent depositional environments ranging from inner ramp and middle ramp with minor outer ramp deposits. Many lithologies appear to be storm influenced due to the presence of abundant rip-up clasts (intraclasts), fragmented bioclasts, and occasional mega-ripples. Other lithologies have been extensively bioturbated and burrowed. Nine stratigraphic sequences have previously been identified within the Pogonip Group. Eight equivalent, albeit compressed, sequences within the Garden City Formation were located using biostratigraphic and chemostratigraphic correlations, and increases in insoluble residues often found at the bases of sequence boundaries. Sequences are expressed as deepening-upward packages containing silty/sandy lowstand deposits that transition into wackestones and lime mudstone-rich highstand deposits. Several sequence boundaries appear to coincide with conodont and/or trilobite extinction events. Important sequence boundaries mark the Sauk III-m and Sauk IV-m transition and the Ibexian- Whiterockian Series boundary. Meter-scale cycles are common and likely related to Milankovitch cyclicity. Insoluble residue increases upsection at each location which may indicate a gradual overall drop in sea level due to the onset of the regressive upper portion of the Sauk III supersequence. Insoluble residue from the Pogonip Group ranges from 1.2 to 84.7 wt. % with an average of 16.0 wt. % ± 0.7 wt. %. Insoluble residue from the Garden City Formation ranges from 1.5 to 63.8 wt. % with an average of 13.4 wt. % ± 1.0 wt. %. New stable carbon isotope data (δ13C) from the Garden City Formation and the Pogonip Group range from -2.92 to 1.23 ‰ V-PDB and -2.19 to 0.56 ‰ V-PDB, respectively. Four distinct δ13C trends are recognized in both sections: 1) a drop in δ13C from positive values between 0.2-1.0 ‰ to negative values approaching -1.0 ‰ near the base of the Ordovician, 2) a 0.5 to 1.0 ‰ positive δ13C excursion near the top of the Rossodus manitouensis Zone, 3) a drop in δ13C values to near -2.0 ‰ through most of the Acodus deltatus –Oneotodus costatus Zone, and 4) a gradual increase in δ13C from - 2.0 ‰ to -1.0 ‰ throughout the remainder of the sections. δ13C of the Garden City Formation and the Pogonip Group appear to be correlative based on these distinct trends. This correlative relationship was verified by the lowest occurrence of conodont species Scolopodus filosus and Scalpellodus n. sp. A of the Low Diversity Interval which coincides with the positive δ13C excursion in both the Garden City Formation and the Pogonip Group. New δ13C data likely represent global primary seawater chemistry based on the correlation of similar δ13C trends from the Argentine Precordillera and western Newfoundland.
