Thesis (M.A. (Translation studies and linguistics)) --University of Limpopo (Turfloop Campus), 2010 / The researcher was motivated to conduct this research because there is a prevalence (high rate) use of code-switching among high school learners, teachers and students in tertiary institutions as well as in Xitsonga texts. This was observed by evaluating selected Xitsonga literature or text books with the aim of investigating why characters in the text books use code-switching as a conversational strategy. Based on the research findings, it became evident that characters/speakers switch because they have a lack of language proficiency, in their language or the target language. Their switch appears to be influenced by their statuses, the lack of equivalent words, the situations they find themselves in and the urge to be socially accepted by their peers. It is recommended that speakers need to learn their language adequately in order to communicate effectively without having to switch

As the technology develops and robots are integrating into more and more facets of our lives, the futureof human-robot interaction may take form in all kinds of arrangements and configurations. In this study, we examined the understandability of di erent conversational strategies in robot-robot communication from a human-bystander standpoint. Specifically, we examined the understandability of verbal explanations constructed under Grice's maxims of informativeness. A prediction task was employed to test the understandability of the proposed strategy among other strategies. Furthermore, participants' perception of the robots' interaction was assessed with a range of ratings and rankings. The results suggest that those robots using the proposed strategy and those using the other tested strategies were understood and perceived similarly. / I takt med att teknologin utvecklas integreras robotar mer och mer i olika delar av våra liv. Framtidens människo-robot interaktioner kan ta många olika former och konfigurationer. I den här studien undersökte vi förståelsen för olika konversationsstrategier mellan robotar ur det mänskliga perspektivet. Specifikt undersökte vi förståelsen av muntliga förklaringar konstruerade enligt Grices princip för informativitet. En uppgift för deltagarna i testet var att försöka förutsäga robotarnas agerande. Dessutom utvärderades robotarnas interaktion genom att låta deltagarna rangordna och betygsätta dem. Resultatet tyder på att de robotar som använder Grices princip och de som använder de andra testade strategierna förstås och uppfattas på ett liknande sätt.
