Redes Sociais e Juventude Rural: apropriações de propostas de Comunicação para o desenvolvimento em redes globalizadas Nataly de Queiroz Lima Maria Salett Tauk dos Santos Comunicación Internet Redes sociais Juventude rural Tecnologias da Informação e da Comunicação Este artigo objetiva analisar as apropriações das propostas da Rede de Crianças e Adolescentes Comunicadores de Língua Portuguesa pelos jovens de Nova Olinda, no sertão do Ceará. Especificamente, o que se quer compreender é como os jovens de contexto popular, submetidos à condição contingente de acesso a bens materiais e simbólicos, se apropriam de uma proposta que defende o desenvolvimento local via estratégias de Comunicação acordadas em uma rede social global. A pesquisa combina as teorias dos estudos culturais latino-americanos e dos estudos das redes sociais, via Manuel Castells, Scherer-Warren, Néstor García Canclini, Maria Salett Tauk Santos e Jesus Martin-Barbero. Trata-se de um estudo de caso que utiliza técnicas combinadas de coleta de dados. A pesquisa demonstra que os jovens rurais estão inseridos nas dinâmicas das redes sociais, mas as mediações tecnológicas não são redentoras para a formação de coletivos internacionais. 2012 artículo científico 1809-5844 https://www.redalyc.org/articulo.oa?id=69831021012 pt http://www.redalyc.org/revista.oa?id=698 Intercom - Revista Brasileira de Ciências da Comunicação application/pdf Sociedade Brasileira de Estudos Interdisciplinares da Comunicação Intercom - Revista Brasileira de Ciências da Comunicação (Brasil) Num.2 Vol.35
