Resumo: | The Ukrainian geneticist Theodosius Dobzhansky (1900-1975) made several visits to Brazil and for four times interacted with the group leaded by Prof. André Dreyfus (1897-1952), of the University of São Paulo. The partnership between Dobzhansky and Brazilian researchers was marked by the development of a project which lasted about twenty years and was supported by the Rockfeller Foundation. The first aim of this dissertation is to evaluate the impact made by Dobzhansky s four visits on the studies of genetics and evolution developed by the Brazilian group. The second aim is to analyse the scientific and extra-scientific factors which lead to the decrease of Brazilian and Dobzhansky s publications related to the subject of the project as well as the end of their partnership. The period considered is from 1943 to 1960. This dissertation contains an introduction and five chapters. The first chapter presents a general view of the scientific context of the period, an overview of Dobzhansky s career and of genetics in Brazil. The second chapter tries to analyse the impact made by Dobzhansky s visits on the studies developed by Dreyfus group using a bibliometric approach. The third chapter deals with the subjects discussed by Dreyfu s group during and after Dobzhansky s visits, studying a significant sample of their works. The fourth chapter tries to elucidate the scientific and extra-scientific factors which contributed to the decrease of Dobzhansky and Brazilians publications related to the subject of the project. The fifth chapter presents some final considerations. This study lead to the conclusion that Dobzhanky s influence on Dreyfus group was significant not only in quantitative terms (the amount of publications beginning with Dobzhansky s first visit), but also in qualitative terms. After Dobzhansky s arrival, Dreyfus group started a new line of investigation (the genetics of populations) adopting a new experimental material (Drosophila) and exploring a little studied region: the tropical one. The decrease of individual and joint publications dealing with the subject of the project during some periods can be explained by the adoption of new experimental materials by some members of the group; the involvement with some subjects which were not part of the initial project, such as Botany; Dobzhansky and his wife s health problems during the third visit; scientific disagreement between Dobzhansky and Brazilians; and Brazilian s desire of independence |

Durante quatro delas interagiu com o grupo liderado pelo Prof. André Dreyfus (1897-1952) da Universidade de São Paulo. A parceria entre Dobzhansky e brasileiros foi marcada pelo desenvolvimento de um projeto que durou cerca de vinte anos e contou com o apoio da Fundação Rockfeller. O primeiro objetivo desta dissertação é avaliar o impacto que estas quatro visitas de Dobzhansky causaram sobre os estudos acerca de genética e evolução desenvolvidos pelo grupo brasileiro. O segundo objetivo é analisar os fatores científicos e extracientíficos que contribuíram para a redução das publicações de Dobzhansky e brasileiros sobre o assunto do projeto e para o final da parceria entre eles. O período considerado é de 1943 a 1960. Esta dissertação contém uma introdução e cinco capítulos. O primeiro capítulo oferece uma visão geral do contexto científico do período estudado, da trajetória de Dobzhansky e da genética no Brasil. O segundo capítulo procura analisar o impacto das visitas de Dobzhansky sobre os estudos desenvolvidos pelo grupo de Dreyfus através de um enfoque bibliométrico. O terceiro capítulo analisa os assuntos tratados em uma amostra significativa dos trabalhos desenvolvidos pelo grupo de Dreyfus durante e após as visitas de Dobzhansky. O quarto capítulo trata dos fatores de ordem conceitual e não conceitual que contribuíram para o decréscimo das publicações conjuntas de Dobzhansky e brasileiros. O quinto capítulo apresenta algumas considerações finais sobre o assunto. Este estudo levou à conclusão de que a influência de Dobzhanky foi significativa tanto em termos quantitativos (quantidade de publicações a partir de sua primeira visita) como em termos qualitativos. Sua vinda fez com que o grupo da USP passasse a se dedicar a uma nova linha de investigação (a genética de populações) adotando um novo material experimental (Drosophila) e explorando a região tropical que havia sido pouco estudada. A redução das publicações individuais e conjuntas sobre o assunto do projeto durante alguns períodos pode ser explicada pela adoção de novos materiais experimentais por parte de alguns membros do grupo; envolvimento com outros assuntos que não constavam no projeto como a botânica, por exemplo; problemas de saúde de Dobzhansky e sua esposa durante sua terceira visita; divergências científicas entre Dobzhansky e brasileiros e desejo de independência dos brasileirosSecretaria da Educação do Estado de São Pauloapplication/pdfhttp://tede2.pucsp.br/tede/retrieve/29995/Jose%20Franco%20Monte%20Siao.pdf.jpgporPontifícia Universidade Católica de São PauloPrograma de Estudos Pós-Graduados em História da CiênciaPUC-SPBRHistória da CiênciaGenética de populaçõesDrosophilaDobzhansky, Theodosius Grigorievich -- 1900-1975GeneticaDrosophila - GeneticaGenetics of populationsDrosophilaCNPQ::CIENCIAS HUMANAS::HISTORIA::HISTORIA DAS CIENCIASTheodosius Dobzhansky e o desenvolvimento da genética de populações de Drosophila no Brasil: 1943-1960info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da PUC_SPinstname:Pontifícia Universidade Católica de São Paulo (PUC-SP)instacron:PUC_SPTEXTJose Franco Monte Siao.pdf.txtJose Franco Monte Siao.pdf.txtExtracted texttext/plain182941https://repositorio.pucsp.br/xmlui/bitstream/handle/13382/3/Jose%20Franco%20Monte%20Siao.pdf.txt09a1170f3fe8283ba9fa22aee5d55591MD53ORIGINALJose Franco Monte Siao.pdfapplication/pdf1556513https://repositorio.pucsp.br/xmlui/bitstream/handle/13382/1/Jose%20Franco%20Monte%20Siao.pdf635978cf87b4bf4ee8d7f5ca3319ec43MD51THUMBNAILJose Franco Monte Siao.pdf.jpgJose Franco Monte Siao.pdf.jpgGenerated Thumbnailimage/jpeg5338https://repositorio.pucsp.br/xmlui/bitstream/handle/13382/2/Jose%20Franco%20Monte%20Siao.pdf.jpg1b45f94ce08077c7b2c517a892434f44MD52handle/133822022-04-27 21:06:09.692oai:repositorio.pucsp.br:handle/13382Biblioteca Digital de Teses e Dissertaçõeshttps://sapientia.pucsp.br/https://sapientia.pucsp.br/oai/requestbngkatende@pucsp.br||rapassi@pucsp.bropendoar:2022-04-28T00:06:09Biblioteca Digital de Teses e Dissertações da PUC_SP - Pontifícia Universidade Católica de São Paulo (PUC-SP)false |
