A metaforização da Amazônia em textos de Euclides da Cunha
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Linguística, Florianópolis, 2013Abstract: This thesis is the result of a research which had as objective analyzing Euclides da Cunha´s metaphorical discourse about Amazonia, and how that discourse is organized in the texts written by this author. The design of this general objective arose from the following research problems: what is Euclides da Cunha´s metaphorical discourse about Amazonia made of? What metaphors does he use to describe Amazonia in his texts? Why did he use so many metaphors to refer to the region? The study has searched for answer(s) to such questions, on the limits of the research nature, which has followed along three big guiding axes: Amazonia, Euclides da Cunha, and Metaphor. Through the analysis of Euclides´s texts, I try to show that he was a good metaphorist. I make the reading of the Amazonian metaphors in Euclides from a classical approaching (initiated by Aristotle), an interactionist approaching (whose precursor was I. A. Richards, and whose main exponent was Max Black), and conceptual approaching (created by George Lakoff and Max Johnson), and the live metaphor (proposed by Ricoeur). I explore, from each one of these theories, metaphors which Euclides da Cunha created for reflecting about his work and for describing geographical and landscaping aspects of Amazonia, as well as the people, social relationships, boundary conflicts, and other region snapshots. I describe Euclides da Cunha´s views on the Amazonia, having as starting point his Amazonian metaphors, and I explore the dichotomy on artistic writing versus scientific writing on the writer´s texts. The study has its support on one basic hypotheses: Euclides da Cunha, on his Amazonian texts, fights two crucial dilemmas: firstly the difficulty of dealing with a threefold boundary he had to pass by: boundaries of territory, of science, and of comprehensible things; secondly, the metalinguistic reflections about his texts, when he stumbles before science crossed lines with fiction, by feeling incompatibility between literary text and scientific text, but at the same time, he does not get rid of the trend of conciliating these two methodologies, inconceivable for him. In this work, I defend the thesis that the metaphor was the recourse found by Euclides da Cunha for dealing with two dilemmas. I develop considerations about this dichotomy in Euclides da Cunha´s writings, taking as basis the theoretical considerations of Ricoeur (1983), Lakoff and Johnson (2002) and Paiva (2005), principally. The methodological way of this thesis was made by the channel of bibliographic research, including on this purpose: the decisive points of travellers´ writing tradition about the Amazonia region, Carvajal´s reports on the nineteenth century; Euclides da Cunha´s texts, mainly those on Amazonia collectanea ? a lost paradise, published in 2003 by Editora Valer in Manaus/Am, besides the author´s active letters where he refers to the region; texts of theories about metaphors regarding different views and reflections on the dichotomy scientific language versus artistic language. The bibliographic research has supplied elements for the theoretical foundation and contributed for reinforcing the analyses and the final version of this thesis. Among the theoretical principles, indispensable for the study support, are the concepts on Amazonia, metaphor, metalanguage, and literature. The checking of different views and slopes on metaphor which I revisit has allowed me to recollect supplementary data, from diverse conceptions, which decisively contributed for enabling me a more diversified view, on different angles, about the main metaphors that Euclides da Cunha created on his interpretation of Amazonia. And, considering that the author´s texts are full of metaphors, I pointed out for this study only those that are relevant for the hypothesis highlighted. The research points out that Euclides wanted to build a language that synthesized the science and art truth. Writing about Amazonia, he has started this discourse, but it was incomplete, like the own earth incompleteness. Euclides has found the key for the metaphor enigma ? it only is able to say the unsayable, translate the untranslatable, embrace the unembraceable. Therefore, Euclides used it without parsimony. Metaphor is introduced there as a bridge over the ineffable abyss. And it still contributes to fill in many troublesome gaps both on scientific and artistic language. So I conclude that both in the case of sertões baianos and Amazonia, it was the metaphors that have redeemed Euclides, giving vigor to his writings and offering an access key to an unfinished world for in a certain way comprehend him

Project ISOLDE: DEPAS ocean-bottom seismometer operations around Tristan da Cunha in 2012-2013
No full textAccording to classic plume theory, the Tristan da Cunha mantle plume played a major role in the rifting of the South Atlantic margins by impinging at the base of the continental lithosphere shortly before or during the breakup of the South Atlantic. Onshore the Tristan mantle plume is associated with the emplacement of the Parana-Etendeka flood basalt province ~132 Ma, and offshore with the age-progressive Walvis Ridge and associated young seamount province. The global data is lacking coverage and therefore resolution around the Tristan da Cunha for shallower mantle depths.
The search for deep-reaching geophysical/thermal anomalies beneath Tristan da Cunha was the starting point for a multi-disciplinary geophysical experiment to acquire passive marine electromagnetic, seismic and bathymetric data within the framework of the SPP-1375 “South Atlantic Margin Processes and Links with onshore Evolution” (SAMPLE) funded by the German Science foundation. The experiment included two expeditions with the German research vessel MARIA S. MERIAN in 2012 and 2013. Between February 2012 and January 2013, a network of 24 ocean bottom seismometers (OBS) from the German DEPAS pool (Deutscher Geräte-Pool für Amphibische Seismologie) and 26 ocean-bottom magneto-telluric stations from GEOMAR Kiel and the University of Tokyo were deployed around the archipelago of Tristan da Cunha.
The seismological stations are equipped with a Güralp CMG-40T wideband seismometer (60 s) incorporated in a titanium pressure housing, a hydrophone, and a GEOLON MCS (Marine Compact Seismocorder) data logger from SEND GmbH Hamburg, Germany. Each sensor channel is sampled at 50 Hz (2 OBS at 100 Hz), preamplifier gain of the hydrophone channel is 4 and 1 for the three seismometer components. The seismometers are connected to a cardanic levelling mechanism, which was activated every 21 days to level the sensors. Based on previous experiments and triangulation of some stations, the accuracy of the positions is estimated to 500 m.
To complement the ocean-bottom network and the existing observatory on Tristan da Cunha (TRIS), two land seismometers and one magnetotelluric station were installed on Nightingale Island located southwest of the main island each of which was equipped with a Güralp-3ESP seismometer (60 s) and an EarthData data logger. As recording parameters, we chose 100 Hz sampling rate and low preamplifier gain (0.4). One of the stations (NIG01) recorded earthquake data for the entire year, while the second station failed after few days due to water damage. Unfortunately, the permanent station TRIS failed also during the experiment
Desilusão republicana: percursos e rupturas no pensamento de Sílvio Romero, Euclides da Cunha e Lima Barreto
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.Este trabalho trata das conseqüências da desilusão política na obra de três intelectuais: Sílvio Romero, Euclides da Cunha e Lima Barreto. A utopia republicana, imaginada por gerações, frustrou ideólogos e militantes com conseqüências nas atividades intelectuais e na composição da esfera política. A tese procura demonstrar a mudança de rumo em suas produções a partir da situação de excluídos do projeto político-cultural republicano que viria a ser dominante. Por essa razão, suas obras, marcadas pela desilusão política, ganharam em maturidade e penetração ao tentar desvendar a complexidade cultural, social e antropológica da realidade nacional que impedia a concretização efetiva do novo sistema de governo. O resultado foi o surgimento de visões críticas e pessimistas sobre o entendimento do que, de fato, era a nação e que se tornaram matriciais nos estudos brasileiros modernos
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

GIS based analysis, processed sub bottom profiler, and composite grid and backscatter mosaics around Tristan da Cunha
No full textTristan da Cunha is assumed to be the youngest subaerial expression of the Walvis Ridge hot spot. Based on new hydroacoustic data, we propose that the most recent hot spot volcanic activity occurs west of the island. We surveyed relatively young intraplate volcanic fields and scattered, probably monogenetic, submarine volcanoes with multibeam echosounders and sub-bottom profilers. Structural and zonal GIS analysis of bathymetric and backscatter results, based on habitat mapping algorithms to discriminate seafloor features, revealed numerous previously-unknown volcanic structures. South of Tristan da Cunha, we discovered two large seamounts. One of them, Isolde Seamount, is most likely the source of a 2004 submarine eruption known from a pumice stranding event and seismological analysis. An oceanic core complex, identified at the intersection of the Tristan da Cunha Transform and Fracture Zone System with the Mid-Atlantic Ridge, might indicate reduced magma supply and, therefore, weak plume-ridge interaction at present times
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
