Plenary “If looks could kill" given at IAVS13 in Bogotá; oddly undermined by parallel session

Today I gave my plenary speech “If looks could kill: The human ecology of visible and overlooked worlds in the perspective of Umwelt phenomenology” at the 13th conference of the International Association for Visual Semiotics (IAVS), held at Universidad de Bogotá Jorge Tadeo Lozano in Bogotá, Colombia. Only 10-16 people attended (beginning-end). Oddly, the organizers, which included the IAVS, had scheduled a session in parallel with my plenary, which defies the notion and purpose of a plenary, which is defined as "a meeting to be attended by all participants at a conference or assembly, who otherwise meet in smaller groups."
