- Description: The purpose of this quantitative research was to improve the way success of software projects is measured. This was done by identifying and exploring external factors that serve as success criteria. It is postulated that by understanding these factors, organisations will be able to focus their resource efforts on the most prevalent factors that they can use to judge software project success. This will ensure project success and ultimately create a competitive advantage for the organisation. The research started off with a structured literature review. This was followed by a research design based on a quantitative questionnaire presenting embedded units of analysis. The results provided a useful insight into the factors that are used to define the success of software projects. The outcome of the study is in the form of a model which highlights the following variables applied to define software project success: system quality, information quality, user satisfaction, net benefits and the traditional variables of time, budget and specification.

- Description: This study seeks to find out what the understanding and adoption of e-finance is by small and medium enterprises (SMEs). The study defines the concepts related to efinance namely, e-services and micro-finance and well as other related IT for development concepts. Firstly, the study identifies benefits of adoption and use of efinance as decreased transaction costs, increased access to financial information and increased access to financial products and services. Secondly the barriers to the adoption of e-finance are identified as poor privacy, security and safety; poor IT telecommunications infrastructure; uncertain IT regulatory and policy and low T training and skills. The results produced by the study confirm a high understanding of e-finance amongst SMEs and all benefits and barriers are confirmed except for one, decreased transaction costs. The study recommends that further research be conducted on this benefit as it may no longer be relevant, especially for developing countries. Limitations of the study include the relatively small sample size and snowballing sampling method used.

- Description: Music education is an essential aspect of education. The South African school curriculum for the Creative Arts combines dance, drama, music and the visual arts. The curriculum uses a combination of the theories of Carl Orff, Emile Jaques-Dalcroze and Zoltán Kodály. Each of these music theorists and educationists have their own distinctive approach to teaching music. This study explores the theories of music education of Carl Orff, Emile Jaques-Dalcroze and Zoltán Kodály. These theories are applied in a critical analysis of both the South African curriculum and the curriculum of New South Wales. The researcher developed music activities to address the shortcomings of both the South African curriculum and the music texts.

- Description: Organisations within the South African automotive industry (SAAI) are always seeking innovative ways to remain globally competitive. In order to keep costs as low as possible, existing facilities are often adapted to either cater for a wider variety of products or, alternatively, to produce larger volumes than they were originally designed to produce. In every instance, some form of change needs to take place. When the change management processes are defined within the system, quick wins need to be identified. These quick wins may include the elimination of non-valueadding time that is spent moving paper work between offices or ensuring the correct checks are in place to prevent the process from moving to the next step until all the requirements for the current steps have been completed. Technology has been identified as a suitable support mechanism that would be able to integrate into the complex system that comprises processes to be followed in an order that can be predefined. Every organisation faces its own unique challenges when technology is introduced. These can include a lack of computer literacy and the unwillingness to accept that change can in fact benefit the organisation. Getting the users to take ownership of the new systems through comprehensive training initiatives will be shown to be the most effective manner in which to ensure that the systems are effective and used to their full potential. This treatise will investigate the change management systems currently being used in the SAAI and compare the most important factors against the perceived best practices of the resources that are involved in change management. Organisations that operate at various levels within the SAAI will be researched. A literature review of the best practices in change management systems combined with an investigation into how technology can assist in supporting these best practices will be conducted. The findings will then be summarised and recommendations based on the collected data and information will be formulated and put forward.

- Description: Home- and community-based care is deeply rooted worldwide and is an integral part of the continuum of health care. This form of care ranges from highly technical and professional services to simple forms of non-professional and voluntary support in homes. Currently a large number of people with HIV related illnesses are being cared for at home by their next of kin and community members as volunteer caregivers. With the continued high number of HIV infections, there is a need to initiate more home- and community-based care centres in South Africa. The study in question explored the challenges and coping strategies of care-givers working in home-based care for people infected with and affected by HIV/AIDS. A qualitative research approach has been employed using an explorative, descriptive and contextual design. The sample was drawn from three home- and communitybased care centres in Cofimvaba, in the Eastern Cape. Semi-structured interviews were used for data collection. Data was analyzed according to the Tesch’s model (1990). The strategy of Lincoln and Guba was used to verify data. Findings indicated that caregivers working in home-based care for people infected with and affected by HIV/AIDS, experienced challenges such as: lack of resources for proper caring; lack of cooperation from the beneficiaries of the caregivers who are getting social grants; influence of community perception on HIV infection on home- and community-based care; and emotional strain on caregivers. Relevant recommendations related to the findings are presented.

- Description: Pneumocystis jiroveci, Mycoplasma pneumoniae and Mycobacterium tuberculosis are respiratory pathogens associated with pneumonia, with increasing prevalence of Pneumocystis pneumonia (PcP) and tuberculosis (TB) in AIDS patients. Increased resistance of M. tuberculosis has emphasized the need for rapid susceptibility testing, such as flow cytometry. Sputum specimens (102) were assessed by PCR employing primers directed at the following genes: P. jiroveci: mitochondrial large subunit ribosomal RNA (mtLSUrRNA), dihydropteroate synthase (DHPS) and dihydrofolate reductase (DHFR), and for M. pneumoniae: 16S rRNA and P1 adhesin. Positive P. jiroveci samples were genotyped by PCR-SSCP (single-strand conformation polymorphism) targeting the: internal transcribed spacer region (ITS), intron of the nuclear 26S rRNA gene (26S), variable region of the mitochondrial 26S rRNA gene (mt26S) and β-tubulin gene (β-tub). Multi-drug resistant (MDR-TB) cultures grown in the presence and absence of four antibiotics (rifampicin, isoniazid, ethambutol and ofloxacin) were heat killed, stained with SYTO16 and Propidium Iodide and analysed using flow cytometry. Rifampicin resistance gene mutations were screened by PCR and DNA sequencing. Details of patient’s gender, age, HIV and M. tuberculosis status were provided by the hospitals. Women were seen to be at high risk for community-acquired P. jiroveci colonisation. Overall, prevalence of P. jiroveci was 55.1 percent (54/102 patients). P. jiroveci was mainly associated with HIV (25/102 P. jiroveci positive patients for which clinical data was available) and co-colonisation with M. tuberculosis was observed in 11 cases. Sequence analysis of DHPS and DHFR products found no resistance associated mutations. M. pneumoniae was detected in one patient. Four simple SSCP patterns were identified and there were no co-infections with other P. jiroveci strains. Nine M. tuberculosis samples [8 MDR-TB isolates (NHLS) and M. tuberculosis ATCC® 27294TM] were tested. There was a 53 percent (19 out of 36 tests) agreement of flow cytometry with the BACTEC MGIT 960. Mutations (at two specific codons, namely 516 and 531) in the rifampicin resistance-determining region (RRDR) of the rpoB gene were observed in eight M. tuberculosis isolates. Evaluation of methods for genotyping and drug susceptibility testing of PcP and TB are imperative for epidemiology and drug resistance studies, and impact on treatment protocols.
