Miradas hacia Latinoamérica: la representación discursiva de los inmigrantes latinoamericanos en la prensa española y estadounidense José Luis Benavides Jessica Retis Comunicación inmigración análisis crítico del discurso formas de representación discursiva El cambio de siglo ha evidenciado el incremento de la inmigración latinoamericana en Estados Unidos y España. Frente a esta presencia, la sociedad autóctona construye representaciones discursivas para (re)conocer esta figura social a la que conoce menos por su naturaleza real que por su construcción simbólica en los medios. Esta propuesta es parte de un proyecto más amplio impulsado por los autores, que implica el análisis crítico del discurso de los periódicos de referencia españoles y estadounidenses, para deconstruir las tendencias en las formas de representación discursiva de la alteridad latinoamericana. 2005 artículo científico 0122-8285 https://www.redalyc.org/articulo.oa?id=64901304 es http://www.redalyc.org/revista.oa?id=649 Palabra Clave application/pdf Universidad de La Sabana Palabra Clave (Colombia) Num.13
