Constituição e institucionalização da ciência: apontamentos para uma discussão Rogério Eduardo Rodrigues Bazi Murilo Artur Araújo da Silveira Ciencias de la Información Constituição da ciência institucionalização social da ciência institucionalização cognitiva da ciência Discute as distinções e relações entre a constituição e a institucionalização de uma disciplina científica. Apresenta os principais componentes de uma ciência, a partir da organização desta, proposta por Bunge (1980). Apresenta os principais elementos que particularizam as perspectivas institucionais da ciência, a cognitiva e a social, baseadas nas contribuições de Whitley (1974; 1980). Ao final, traz um quadro de referências relacionados aos tópicos discutidos quanto à constituição e à institucionalização da ciência. 2007 artículo científico 0103-3786 https://www.redalyc.org/articulo.oa?id=384334784004 pt http://www.redalyc.org/revista.oa?id=3843 Transinformação application/pdf Pontifícia Universidade Católica de Campinas Transinformação (Brasil) Num.2 Vol.19
