Item Policy lessons from assessing computer-use in secondary schools in a provincial capital, Polokwane(2014-02-21) Ghoord, EbrahimThis study examined different elements within the classroom, school and environment in order to establish their influence on technology implementation in schools. A review of the literature suggests that the integration of computers in schools is influenced by a number of separate but inter-related factors. If technology implementations in schools are to achieve the desired objectives as outlined in the e- Education White Paper, it is important that such efforts are cognizant of the unique characteristics of each school setting. Eight schools in Polokwane (Limpopo, South Africa) were chosen for this study, which was intended to evaluate current technology integration efforts against existing policy; and to see what policy lessons may be drawn from this.Item The influence of effectuation and technology orientation on firm performance in the renewable energy sector of South Africa(2013-08-28) Heydenrych, James AndrewThis research study analyses a conceptual model investigating the effect of firms’ choice of effectuation or causation processes in strategy formation and firm performance, the effect of firms’ technology orientation in firm performance, and the relationship between effectuation and technology orientation. The study employed a quantitative approach, surveying data from 73 firms in the renewable energy sector of South Africa, using measurement instruments extracted from prior research. By means of multiple regression analysis, the study found that of the effectuation processes, the use of pre-commitments is significantly and positively associated with firm performance. Furthermore, it was found that a pioneering technology orientation is significantly and positively associated with firm performance. The study also found evidence to support the hypothesis that effectuation is closely linked with pioneering. The study contributes to the field of effectuation research by continuing to move the field towards an intermediate phase, by providing valuable insight into the practicalities of the quantitative analysis of effectuation and the problems that arise therein, in particular, issues surrounding measurement aspects. Moreover, by examining performance differentials, this study seeks to increase the relevance of effectuation theory and expand it from a theory of mere description of entrepreneurial behaviour to a theory that identifies performance-enhancing measures. For practitioners and policy makers, this research provides valuable insight into the drivers of entrepreneurial success and the fostering of entrepreneurial activity both in start-ups and existing corporations to spur innovation, productivity, and growth in the economy.Item Factors supporting the intention to use e-prescribing systems: health professionals' use of technology in a voluntary setting(2013-07-16) Jones, Michael EdwardIllegible written prescriptions and “Doctor’s handwriting” may have been synonymous, but this stereotype has begun to change with the gradual uptake of e-prescriptions. These eprescriptions are electronically captured and delivered prescriptions, and are touted as the solution to the many medical risks caused by written prescriptions. Whilst there is published support for the benefits of e-prescriptions, the uptake of e-prescribing has been too gradual for all patients to enjoy these benefits. The inadequate research into physicians’ adoption of e-prescribing systems presents a need for further study in this area, in an effort to improve the general use of these systems. Based on a review of literature, this study proposes six factors which may explain physicians’ intentions to use e-prescribing systems. These factors are based upon the Unified Theory of Acceptance and Use of Technology (UTAUT). This model is extended in this study by Social Dominance Theory, Commitment-Trust Theory and the Product Evaluation Model. Quantitative data was collected to test the proposed hypotheses. This data was gathered from physicians who have had some exposure to an e-prescription system. 72 usable responses were obtained for this study. The results of the study suggest that Performance Expectancy and Price Value have the highest influence on Behavioural Intention. Effort Expectancy and Social Influence had no direct influence on Behavioural Intention when in the presence of other variables, but they, along with Trust, had an indirect effect on Behavioural Intention through Performance Expectancy. Surprisingly, Social Dominance Orientation was not found to have an influence on Behavioural Intention. Implications, contributions and further research are discussed.
