    ABSTRACT: This observational, descriptive, transversal study sought to establish prevalence, frequency, risk factors and university context features in a private University in Bogota, Colombia, all associated to smoking in the University population (n=973) in 2008-2009. Results suggest confirming that experimenting with these substances is related to environmental variables such as availability and ease of Access, besides positive valuing practices towards smoking, exhibited by the participants' reference groups. We noticed that, whilst it is true that smoking may have been learnt before being a part of the University community, the University itself is a social reinforcement context, which encourages the excessive following of behavioural rules. It means that University context promotes social behaviour modes that lie under control of a history of correspondence between rules and natural contingencies in social interaction, as noticed by all groups when they pointed to social factors as the element with the most weight when deciding to smoke.

    ABSTRACT: Twenty years after his death (August 18 th 1990), B. F. Skinner leaves five major living legacies: 1) radical behaviorism; 2) the experimental analysis of behavior; 3) applied behavior analysis; 4) the Skin-ner box; 5) the Horcones community (Mexico). Behavior analysis is recognized for its international active presence. Its growth provides a set of oppor-tunities for knowledge and technology transference and reminds us the importance of working for the development of educational and research programs and the arrangement of contingencies which enable its advance. In Ibero-America, behavior analysis, as a Skinnerian legacy, has been an important tradition within psychology. In this article we will present a current synthesis of the central Ibero-American contributions to Behavior analysis. The panorama of Behavior analysis in Ibero-America will be analyzed according to the following dimensions: 1) the most relevant figures; 2) the academic com-munity related to the Behavior Analytic tradition; and 3) the most important research lines. Finally, some of the most general characteristics of Ibero-American Behavior analysis are included.
