Comunicação, tecnologia e subjetividade: apontamentos estratégicos Wilton Garcia Administración y Contabilidad Linguagem Tecnologia Comunicação Subjetividade Estudos contemporâneos Este texto desenvolve uma reflexão crítica sobre comunicação e tecnologia enquanto produção de conhecimento e subjetividade, ao considerar os aspectos socioculturais e políticos. Como atribuir (re)dimensões de valores ideológicos aos tecnológicos? Nesse contexto, privilegia-se uma situação emergente acerca da implantação do Sistema Brasileiro de Televisão Digital (SBTVD). Corpo, experiência e imagem elencam-se como categorias críticas, as quais se inscrevem de modo diluído ao longo dessa pesquisa, a partir da linguagem – estratificada entre cultura e representação. Dos estudos culturais às novas tecnologias, evocam-se os estudos contemporâneos (do corpo, da cultura, da linguagem e das novas tecnologias). Assim, tais estudos (BHABHA, 1998; CANCLINI, 1998; COSTA, 2004; EAGLETON, 2005; GUMBRECHT, 1998; HALL, 2003; HUTCHEON, 2000; LÉVY, 1999; MATURANA, 1997; YÚDICE, 2004), estrategicamente, contextualizam uma abordagem teórico-metodológica para evidenciar noções de atualização e inovação. A metodologia, aqui, constitui-se a partir da descrição de objetos e respectivos contextos a serem investigados de modo multidisciplinar. 2008 artículo científico 2177-5184 https://www.redalyc.org/articulo.oa?id=471747517010 pt http://www.redalyc.org/revista.oa?id=4717 Revista Brasileira de Marketing application/pdf Universidade Nove de Julho Revista Brasileira de Marketing (Brasil) Num.1 Vol.7
