The topic of native and ethnic radio, as part of the lack of
research on radio in Colombia, has been poorly developed
(Cuesta Moreno, 2012a, 2012b). This article shows three study
cases: Radio Nasa of Nasa Community, Jujunula Makuira of Wayuu
Community, and Al A With A Wan program of native community
from San Andrés island; it also explores the identity perspectives
that find negotiation spaces in radio production, especially the
relationship of their collective identity and the way it affects or
determines its linguistic use. This research is based on a threestage
process where producers (practice communities) (Wenger,
1998) make a reflection on their function and issue concepts on
the way their identity is reflected from the construction of their
programming. Results show that several levels of affiliation to
several identification facets make it possible to relate, in several
manners, the communication work of radio and that these
identifications present in the practice communities have a real
impact on the linguistic radio production of each community.

In this article, we talk about intercultural communication from a pragmatic point of view. We will present, in detail, interaction notions, context, culture, and the proxemic theory. These factors will serve as a reflection around testimonies provided by an intercultural communication seminar held at the campus of Lovaina the New, in Belgium. Finally, we will present some notions of cultural shock, negotiation, and meta-communication, as key concepts to face conflicting intercultural relations and for achieving a satisfactory cultural integration.
