It pays attention to message propagation by sanctioned and clandestine radio stations in pre- and post-independent Zimbabwe. This dissertation uses two models of message propagation in a limiting information environment: Sturges' information model of national liberation struggle and Chatman's small world information model. All the message propagation elements in the Sturges and Chatman's models are present in the broadcast texts analyzed. However, the findings of this dissertation indicate that communication in a restrictive information environment is designed such that its participants make sense of their situation, and come up with ways to solve the challenges of their small world. Also, a restrictive information environment is situational, and message propagators operating in it are subject to tactical changes at different times, accordingly altering their cognitive maps. The two models fail to address these concerns. This dissertation focused on message propagation in Zimbabwe because there is military belligerence involved in the information warfare. It therefore provides an extreme situation, which can help our understanding of more everyday instances of communication and interference of communication. Findings of this dissertation recommend the need to emphasize that information input, output and suppression are components dependent on each other; not discrete and independent categories of information activities.","abstract_html":"This dissertation seeks to identify the elements that inform the model for competing message propagation systems in a restrictive environment.
