Quilombo y apuesta: apuntes etnográficos sobre la crisis argentina de 2001 a través de la mirada del mundo del dise?o
Guerschman,Bárbara; Vargas,Patricia;
Av?? , 2007,
Abstract: this article tries to explore how the crisis lived in argentina in 2001 has been resignified by a group of objects and cloth producers, who refer themselves as designers. in this sense, we will focus on the perspectives that these producers have about the different dimensions of this crisis (economical, political, cultural, moral, etc.), on how it affected the course of their productive and professional activities, and their images about the future of their country. from the analysis of the ethnographic material -produced from open interviews and observations in design public events - it was possible to differentiate two main interpretations about the crisis. even being perceived by the designers as catastrophe, chaos and uncertainty, at the same time, the crisis was also perceived as a chance, offering a favorable context for the development of their own enterprises.
Quilombo y apuesta: apuntes etnográficos sobre la crisis argentina de 2001 a través de la mirada del mundo del dise o
Bárbara Guerschman,Patricia Vargas
Avá : Revista de Antropología , 2007,
Abstract: El objeto de este artículo consiste en explorar cómo ha sido resignificada - seis a os después- la crisis argentina de 2001 por un grupo de productores de objetos e indumentaria que se identifican a sí mismos profesionalmente como dise adores. En este sentido nos centraremos en las perspectivas de estos peque os empresarios acerca de las diferentes dimensiones que adquirió la crisis (económica, política, cultural, moral, etc.) y de qué maneras incidió en la trayectoria de sus actividades productivas y profesionales, así como en sus imágenes acerca del futuro del país. A partir del material etnográfico -producido en base a entrevistas abiertas y observaciones en eventos públicos de dise o- fue posible advertir dos lecturas respecto a la crisis: si bien ésta fue percibida en términos de catástrofe, caos e incertidumbre, al mismo tiempo fue percibida como una oportunidad, como la posibilidad del ejercicio de una apuesta, operando como contexto propicio para el desarrollo de emprendimientos propios.
