Cognitive Maps (CMs) have shown promise as tools for modelling and simulation of knowledge in computers as representation of real objects, concepts, perceptions or events and their relations. This thesis examines the application of fuzzy theory to the expression of these relations, and investigates the development of a framework to better manage the operations of these relations. The Fuzzy Cognitive Map (FCM) was introduced in 1986 but little progress has been made since. This is because of the difficulty of modifying or extending its reasoning mechanism from causality to relations other than causality, such as associative and deductive reasoning. The ability to express the complex relations between objects and concepts determines the usefulness of the maps. Structuring these concepts and relations in a model so that they can be consistently represented and quickly accessed and anipulated by a computer is the goal of knowledge representation. This forms the main motivation of this research. In this thesis, a novel framework is proposed whereby single-antecedent fuzzy rules can be applied to a directed graph, and reasoning ability is extended to include noncausality. The framework provides a hierarchical structure where a graph in a higher layer represents knowledge at a high level of abstraction, and graphs in a lower layer represent the knowledge in more detail. The framework allows a modular design of knowledge representation and facilitates the creation of a more complex structure for modelling and reasoning. The experiments conducted in this thesis show that the proposed framework is effective and useful for deriving inferences from input data, solving certain classification problems, and for prediction and decision-making.

This thesis aims to develop an inter-organisational knowledge transfer (KT) framework for SMEs, to help them have better understanding of the process of the KT between a SME and its customer (or supplier). The motivation is that knowledge management issues in SMEs is very neglected, which is not in line with the importance of SMEs in the UK national economy; moreover, compared to KT within an organisation, between organisations is more complicated, harder to understand, and has received much less attention. Firstly, external knowledge is generally believed to be of prime importance for SMEs. However, there is little empirical evidence to confirm this hypothesis. In order to empirically evaluate the hypothesis, and also specifically to identify SMEs' needs for external knowledge, a mail questionnaire survey is carried out. Then, based on the key findings of the survey, some 5MB managers are interviewed. The conclusions triangulated from both the key findings and the interview results strongly support the hypothesis, and demonstrate that SMEs have very strong needs for inter-organisational KT, and thus provide very strong empirical underpinning for the necessity of the development of the framework. Secondly, drawing support from a process view, a four-stage process model was proposed for inter-organisational KT. Then a co-ordinating mechanism underpinned by social networks and organisational learning is developed. The process model, co-ordinating mechanism together with cultural difference between organisations constitute an initial framework. Through interviews with SME managers, the initial framework is revised a final framework. The framework validation exercise shows that the final framework could help SMEs have better understanding of the KT. In order to remind and help SMEs to address the 'boundary paradox' embedded in interorganisational KT, and further reflect its complexities and difficulties, the important factors related to each stage of the framework are identified from a strategic perspective, with the help of the co-ordinating mechanism and relevant literature. The factors are also verified by interviews in SMEs. As a result, the initial factors are revised by removing the factors that are perceived as unimportant. The interview results demonstrate that the important factors, as a checklist, can remind and help SMEs to address the 'paradox', and are thus very useful for them.

Teachers tend to use traditional teaching methods, even though young learners are more digitally oriented. The purpose of this study was to analyse teachers' understanding and practices in grade R classes to clarify their use of digital play for language acquisition. The participants consisted of eight grade R teachers at one selected primary school in an urban area that had access to digital technology. Bronfenbrenner's ecological systems theory as a theoretical framework informed this study. This qualitative single case study generated data from teacher participants and their interaction with the learners. The data generation included semi-structured individual interviews, focus group interviews, and non-participant observations. Analyses to answer the research questions were conducted by means of thematic analysis. The main finding was that grade R teachers have some knowledge and understanding of digital play and they are willing to try new games, but they feel they need to know more about digital technology and the use of digital games for language acquisition. Recommendations include the need for the development of more digital games relevant to language acquisition and for teachers to adopt relevant pedagogies to benefit from available digital games. A similar study in a rural area and a comparison between this study and such a study will then be useful in determining teachers' understanding and use of digital play for language acquisition. / Onderwysers is geneig om tradisionele onderrigmetodes te gebruik, selfs al is jong leerders meer digitaal georiënteerd. Die doel van hierdie studie was om onderwysers se begrip en praktyke in graad R-klasse te ontleed, om hul gebruik van digitale spel vir taalverwerwing duidelik te maak. Die deelnemers het bestaan uit agt graad R-onderwysers by een uitgesoekte laerskool in ʼn stedelike gebied, met toegang tot digitale tegnologie. Hierdie studie is geïnspireer deur Bronfenbrenner se ekologiese stelselteorie as ʼn teoretiese raamwerk. Hierdie kwalitatiewe enkelgevallestudie het data van onderwyser-deelnemers en hul interaksie met die leerders gegenereer. Die datagenerering het halfgestruktureerde individuele onderhoude, fokusgroeponderhoude en niedeelnemer-waarnemings ingesluit. Die vernaamste gevolgtrekking was dat graad R-onderwysers oor ʼn mate van kennis en begrip van digitale spel beskik en dat hulle bereid is om nuwe speletjies te probeer, maar hulle voel hulle behoort meer te weet van digitale tegnologie en die gebruik van digitale speletjies vir taalverwerwing. Aanbevelings sluit in: die behoefte aan die ontwikkeling van meer digitale speletjies wat op taalverwerwing betrekking het; en dat onderwysers tersaaklike pedagogieë moet inspan om uit die beskikbare digitale speletjies voordeel te trek. ʼn Soortgelyke studie in ʼn landelike gebied en ʼn vergelyking tussen hierdie studie en so ʼn studie sal dan nuttig wees om onderwysers se begrip en gebruik van digitale spel vir taalverwerwing te bepaal. / Barutiši ba na le go šomiša mekgwa ya sekgale ya go ruta, le ge e le gore baithuti ba baswa ba na le tsebo ya theknolotši.
