A educação popular na América Latina: um estudo comparado do pensamento social de Simón Rodríguez (Venezuela, 1771-1854) e Antônio Carneiro Leão (Brasil, 1887-1966)

Esta pesquisa aborda como temática a Educação Popular em Simón Rodríguez (1771-1854) e Antônio Carneiro Leão (1887-1966), intelectuais da América Latina. A questão norteadora deste processo investigativo é: no contexto de estruturação dos Estados-nação latinoamericanos, como os intelectuais Simón Rodríguez e Antônio Carneiro Leão pensavam a Educação popular? Como hipóteses, entendemos que: 1) Estes intelectuais tecem fios tênues que auxiliaram na significação do conceito de Educação Popular na atualidade, seja por meio da negação seja pela defesa de princípios que atualmente permeiam a conceituação da Educação Popular, ainda que o sentido atribuído à Educação Popular por eles à época não correspondam exatamente à significação presente; 2) Simón Rodríguez e Antônio Carneiro Leão, mesmo de lugares diferentes, um na Venezuela, outro no Brasil, expressaram em suas obras pensamentos com certas semelhanças no que tange à ideia de Educação Popular na América Latina. Com base na questão e hipóteses apresentadas adotou-se como objetivo geral: analisar, por meio do estudo comparado do pensamento social e da teoria descolonial, as formulações de Educação Popular em Simón Rodríguez e Antônio Carneiro Leão, com vistas a sua relação com o contexto latino-americano. Como objetivos específicos, definiu-se: a) contextualizar o conjunto de obras de Simón Rodríguez e Antônio Carneiro Leão, enfatizando os escritos sobre educação, particularmente os enunciados que tratam da idéia de Educação Popular; b) situar o pensamento dos autores no contexto histórico mais geral de seus países; c) analisar as concepções teóricas de Simón Rodríguez (exemplo de pensamento venezuelano) e compará-las com as concepções teóricas de Antônio Carneiro Leão (um exemplo de pensamento brasileiro), de modo a verificar quais os pontos convergentes e divergentes sobre a ideia de Educação Popular; d) Compreender as implicações da proposta de Educação Popular de Simón Rodríguez e Antônio Carneiro Leão para o movimento educacional latino-americano. No plano teórico-metodológico, a pesquisa se fundamenta na História Cultural (representações sociais e lutas de representações), na História Intelectual (memória coletiva e utilizagens mentais) e na Teoria Descolonial (exterioridade). Os resultados revelam que Simón Rodríguez e Carneiro Leão ao apontarem no século XIX e início do século XX a necessidade de valorização cultural das classes populares se aproximam significativamente das concepções de educação popular na atualidade. Também indicam uma similitude entre a realidade colonial hispanoamericana e a realidade luso-brasileira que aproximam essas concepções. Resguardadas as nuances históricas dos países em que nasceram e viveram os autores estudados, constatou-se que estes compreendem a educação como um instrumental imprescindível para a superação da colonização e, portanto, de consolidação da independência política, econômica e cultura do continente. Ao incursionar pela obra dos autores, sob um olhar regido pela Teoria Descolonial, identificamos que o Liberalismo, o Positivismo e as Teorias Raciais produzidos no Ocidente europeu fundamentaram o pensamento intelectual de Simón Rodríguez e Carneiro Leão, mas assumiram outras dimensões ao serem pensadas em meio às experiências vividas pelos autores no continente americano. Sensíveis ao sofrimento de uma população mestiça que não mais poderia viver fora dos parâmetros da modernidade, esses autores, que destacam a educação como um instrumental necessário à libertação política, econômica e cultural da América Latina, defendem, na teoria e na prática, um projeto educacional que fosse capaz de salvaguardar venezuelanos e brasileiros das marcas deixadas pela colonização.

Max Abraham's and Tullio Levi-Civita's approach to Einstein Theory of Relativity

This work deals with the theory of Relativity and its diffusion in Italy in the first decades of the XX century. Not many scientists belonging to Italian universities were active in understanding Relativity, but two of them, Max Abraham and Tullio Levi-Civita left a deep mark. Max Abraham engaged a substantial debate against Einstein between 1912 and 1914 about electromagnetic and gravitation aspects of the theories. Levi-Civita played a fundamental role in giving Einstein the correct mathematical instruments for the General Relativity formulation since 1915. This work, which doesn't have the aim of a mere historical chronicle of the events, wants to highlight two particular perspectives: on one hand, the importance of Abraham-Einstein debate in order to clarify the basis of Special Relativity, to observe the rigorous logical structure resulting from a fragmentary reasoning sequence and to understand Einstein's thinking; on the other hand, the originality of Levi-Civita's approach, quite different from the Einstein's one, characterized by the introduction of a method typical of General Relativity even to Special Relativity and the attempt to hide the two Einstein Special Relativity postulates.

Impact of anthropogenic stressors on the population genetics of the common bioindicator Dreissena polymorpha (Pallas, 1771)

Toxicant inputs from agriculture, industry and human settlements have been shown to severely affect freshwater ecosystems. Pollution can lead to changes in population genetic patterns through various genetic and stochastic processes. In my thesis, I investigated the impact of anthropogenic stressors on the population genetics of the zebra mussel Dreissena polymorpha. In order to analyze the genetics of zebra mussel populations, I isolated five new highly polymorphic microsatellite loci. Out of those and other already existing microsatellite markers for this species, I established a robust marker set of six microsatellite loci for D. polymorpha. rnMonitoring the biogeographical background is an important requirement when integrating population genetic measures into ecotoxicological studies. I analyzed the biogeographical background of eleven populations in a section of the River Danube (in Hungary and Croatia) and some of its tributaries, and another population in the River Rhine as genetic outgroup. Moreover, I measured abiotic water parameters at the sampling sites and analyzed if they were correlated with the genetic parameters of the populations. The genetic differentiation was basically consistent with the overall biogeographical history of the populations in the study region. However, the genetic diversity of the populations was not influenced by the geographical distance between the populations, but by the environmental factors oxygen and temperature and also by other unidentified factors. I found strong evidence that genetic adaptation of zebra mussel populations to local habitat conditions had influenced the genetic constitution of the populations. Moreover, by establishing the biogeographical baseline of molecular variance in the study area, I laid the foundation for interpreting population genetic results in ecotoxicological experiments in this region.rnIn a cooperation project with the Department of Zoology of the University of Zagreb, I elaborated an integrated approach in biomonitoring with D. polymorpha by combining the analysis techniques of microsatellite analysis, Comet assay and micronucleus test (MNT). This approach was applied in a case study on freshwater contamination by an effluent of a wastewater treatment plant (WWTP) in the River Drava (Croatia) and a complementary laboratory experiment. I assessed and compared the genetic status of two zebra mussel populations from a contaminated and a reference site. Microsatellite analysis suggested that the contaminated population had undergone a genetic bottleneck, caused by random genetic drift and selection, whereas a bottleneck was not detected in the reference population. The Comet assay did not indicate any difference in DNA damage between the two populations, but MNT revealed that the contaminated population had an increased percentage of micronuclei in hemocytes in comparison to the reference population. The laboratory experiment with mussels exposed to municipal wastewater revealed that mussels from the contaminated site had a lower percentage of tail DNA and a higher percentage of micronuclei than the reference population. These differences between populations were probably caused by an overall decreased fitness of mussels from the contaminated site due to genetic drift and by an enhanced DNA repair mechanism due to adaptation to pollution in the source habitat. Overall, the combination of the three biomarkers provided sufficient information on the impact of both treated and non-treated municipal wastewater on the genetics of zebra mussels at different levels of biological organization.rnIn my thesis, I could show that the newly established marker set of six microsatellite loci provided reliable and informative data for population genetic analyses of D. polymorpha. The adaptation of the analyzed zebra mussel populations to the local conditions of their habitat had a strong influence on their genetic constitution. We found evidence that the different genetic constitutions of two populations had influenced the outcome of our ecotoxicological experiment. Overall, the integrated approach in biomonitoring gave comprehensive information about the impact of both treated and non-treated municipal wastewater on the genetics of zebra mussels at different levels of biological organization and was well practicable in a first case study.
