- Description: A comprehensive battery of commonly used neuropsychological tests, including the WMS Associate Learning and Visual Reproduction subtests, forming the focus of this study, were administered to a southern African sample (n = 33, age range 18-40). This sample composed of black South African, IsiXhosa speakers with an educational level of Grade 11 and 12, derived through DET and former DET schooling. The gender demographics were as follows; females n = 21 and males n = 12. This sample was purposefully selected based on current cross-cultural research which suggests that individuals matching these above-mentioned demographics are significantly disadvantaged when compared to available neuropsychological norms. This is due to the fact that current norms have been created in contexts with socio-cultural influences; including culture, language and quantity and quality of education distinctly dissimilar to individuals like that composed in the sample. Hence the purpose of this study was fourfold namely; 1) Describe and consider socio-cultural factors and the influence on test performance 2) Provide descriptive and preliminary normative data on this neuropsychologically underrepresented population 3) Compare test performance between age and gender through stratification of the sample and finally to 4) Evaluate the current norms of the two WMS subtests and assess their validity for black South Africans with DET and former DET schooling with comparisons to the results found in the study. Information derived from the statistical analyses indicated that a higher performance in favour of the younger group over the older age range was consistently found for both WMS subtests. With regards to gender, some higher means were evident for the male population in the sample than was produced by the female group. Lastly, due to the fact that most scores derived from the sample were considerably lower when compared to the available norms, it is felt that socio-cultural factors prevalent to this population are a significant cause of lower test performance and thus warrant the development of appropriate normative indicators.

- Description: The well-known concept of a Project Manager managing an I.T. project in relative isolation is no longer a viable option for organisations that are running numerous projects simultaneously. Due to the enormous costs and risks involved in many of these projects, there needs to be a means to ensure success. This has led to the establishment of the concept of a Project Management Office (PMO). An autonomous business unit that is responsible for managing all projects within an organisation. The need for a Project Management Office (PMO) to effectively manage multiple projects is becoming more and more accepted worldwide. The benefits of a PMO are well documented, but whether these benefits will apply to organisations within the NMM area needed to be investigated. A detailed analysis of the benefits of Project Management and in particular a PMO, have been investigated by means of a literature study. An investigation into the effectiveness of PMO’s in South Africa in general, was conducted by means of a survey targeted at a group of I.T. Project Managers located in all the major centres. A further survey was conducted among local I.T. managers to determine their current level of success and their expectations for the future. When reviewing the expectations of local I.T. management against the performance of Project Managers that are currently operating within PMOs, it is clear that organisations within the NMM area are in need of PMO’s and would certainly benefit from their establishment.

- Description: The primary purpose of this research was to investigate the extent to which rural schools understand and perceive the concept of participative management. The concept of participative management has been viewed as an ideal style of leadership and management for school development purposes. In South Africa’s case, it is an educational policy which is expected to reign in all school management bodies. Many theorists envisaged participative management as enhancing active involvement of relevant stakeholders and it has been advocated by many scholars who believe it is the best leadership style in implementing democratic values to education, particularly South African rural education, which is still in a transitional stage. As an interpretive orientated study, this research had an interest in understanding the research participants’ subjective experiences as well as their general perception of participative management. As case-study-driven research, it sought to investigate their understanding of the concept in their natural setting. This included various meanings they aligned with and attached to participative management, their attitudes, their interpretations and feelings towards it. The study employed a focus group data gathering technique in collecting data. The findings of this study suggest that participative management has been embraced by rural school management to a certain extent. There are potentially positive aspects that have been brought by participative management to the school, namely, shared vision, common goals, shared decision-making and general involvement of relevant stakeholders. However, the study has depicted a lack of ethical values on the side of some stakeholders and this hinders the smooth implementation of participative management. The study has also revealed that there are challenges facing rural schools in terms of parental involvement in school governance. Challenges such as lack of commitment to the school, illiteracy among adults and communication breakdown between the school and its parents are still rife in rural schools. Besides these challenges, the blood of participative management is flowing steadily in the veins of the rural school communities.

- Description: This collection of research projects tells a story of the time I have spent with members of the Albany Working for Water team; including preparations made, lessons learned and insights gained. My first project was to analyse the methodology of a research paper. I chose the paper by Arjen Wals because I intended, like him, to examine people's perceptions of environmental issues. From this paper I gained ideas for a qualitative research process and learnt the importance of theoretical and methodological consistency. My next project was to present a report on my research into the perceptions of workrelated environmental issues among the Albany Working for Water workers. From this research I gained insight into the knowledge of the workers and also some of the misconceptions that they have about social and ecological issues. I made educational recommendations based on these insights. This experience inspired me to initiate a play with a group of the workers about alien plant eradication. The process of developing this play formed the basis for a research paper that I have submitted as another research project. Concurrent with the development of the play, I conducted a fourth research project that was a situational analysis of the Albany Workingfor Water Project. I hoped that this analysis would provide useful insight into the context of the above two projects. Overall, I hope the story reflects how I have grown through the learning experiences I shared with the Albany Working for Water team. I would like to extend to my thanks to all those who assisted and shared my journey with me.

- Description: This paper presents the outcome of two case studies and a survey of manufacturing and engineering industries in the Eastern Cape, to explain their environmental education and / or training needs. The methods involved in case studies were interviews, observation and document analysis and for the survey a postal questionnaire. Respondents were generally able to identify their companies' environmental impacts and most thought that education and/training has a role to play in helping them deal with those impacts. While respondents identified environmental awareness for workers as the main role that education and / or training can play, it also has to help management understand its environmental role in dealing with environmental management systems and legislation, as well as supporting education and training. Education and/or training should take both managers and workers beyond the superficial understanding of the concept of environment. In-house and external trainers were identified as potential trainers as this would both overcome a current lack of capacity and make continuity possible when external trainers cease training. Trainers should be environmentally qualified. Respondents have mostly shown support for learning-on-the-job but less so on special environmental courses or including an environmental component in all training programmes. Some training sections consider their sections as already overladen and unable to accommodate other training programmes. The problem is therefore more logistic than environmental.

- Description: This thesis uses Hirsch's dual notion of intention, i. e. conscious, intentional meaning and symptomatic, unconscious meaning, in order to avoid a dead end in the critical assessment of Warhol's work. T.S. Eliot's term "objective correlative" refers to a phenomenon whereby "an inner emotional reality" is evoked by its "external equivalent". (Benet, 1965). Thus, given that no work of art is purely self-referential (as distinct from its being autonomous),Hirsch's notion allows that viewerreconstruction of a painting involves shared values and concerns; that a painting reconstructed by a viewer acquires the status of an icon through which the viewer participates in the artist's sacred cosmos. Sociology of art tends on the whole to extrapolate from actual works to the alleged conditions that gave rise to them. That it cannot predict what specific works will arise from given conditions makes it unscientific. However, its usefulness lies in its ability to reveal what values and concerns are shared by artist and viewer. This is vital for an interpretation of Warhol's work. Warhol's biography leads directly into the meaning of his work. The sickly child of an immigrant steelworker, he grew up in Pittsburgh - an epitome of the technocratic-industrial environment - and was exposed from an early age to a violent and ugly world where the disparity between the super-wealthy and the struggling workers was deeply disturbing. That Warhol himself became a multi-millionaire artistic tycoon is significant, for it means that his works, his icons, were participatory in the very cultural myths and neuroses they appear to display or even despise. That his work has meaning and is open to interpretation there is no doubt. For example, a man-made soup can, as a manifestation and containment of the sacred, is coercive. Here the sacred becomes familiar, affordable and disposable. An electric chair, a man-made instrument of death, gives man supremacy over mortality and the divine prerogative of purging the world of all evil. The essay, however, does not attempt to answer the broader questions raised by Fromm and Roszak about the spiritual emptiness of the twentieth century and the existential crises experienced by those who hunger for meaning and fasten greedily onto anything that seems to proffer a glimpse of something beyond. The essay, nevertheless, strives within this context to elucidate the valid in Warhol's work

- Description: A major objective of Academic Development Programmes is to support the student in acquiring a level of language competence which is sufficient to enable the student to cope with the linguistic demands of academic courses. Language teaching programmes in the Academic Development context in South Africa suffer from a number of constraints: staffing, time on task, relevance, and difficulty of integration with learning in other coUrses. A review of developments in the field of Computer Assisted Language Learning (CALL) shows that computers can be used to support language learning. CALL materials range from simple instructional programs to powerful linguistic research tools and need to be integrated into wider language programmes so as to support and enhance other teaching and learning activities. However, relatively little research has been done to investigate the feasibility and effectiveness of CALL in language development courses within Academic Development programmes in South Africa. The development of a system designed to enable students to practise proof-reading and editing is described and evaluated. Suggestions are made for using this system with other CALL materials within a computer assisted language development environment. It is argued that CALL can be used feasibly and effectively in this environment to enhance learning and to counteract constraints.

Regional tectonic and climatic conditions as well as gold source are considered. The characteristics of eluvial, alluvial, marine, glacial and fluvioglacial gold placer deposits are described. Particular attention is paid to the gold grains within these placers. These gold grains have a distinctive morphology and chemical composition which reflect the manner in which they were transported, deposited and concentrated within the placers. The knowledge of the processes which lead to the formation and location of surficial gold placers is then used to guide exploration and target potential deposits, which can then be evaluated.

- Description: A highly sulphated, methylated polysaccharide, aeodan, isolated from the red seaweed Aeodes orbitosa was shown to contain galactose, 2-̲̲O-methyl-D-galactose, 4-O̲-methyl-Lgalactose, 6-O̲-methyl-D-galactose, xylose, and glycerol. The polysaccharide was desulphated with methanolic hydrogen chloride. Periodate oxidation of aeodan and desulphated aeodan, followed by reduction and hydrolysis, revealed the presence of 1,4- and 1,3-linked galactose residues and 1,3-linked 6-O̲-methy l-D-galactose residues in aeodan. Treatment of aeodan with sodium hydroxide revealed that the majority of the ester sulphate groups were alkali stable. Methylation of desulphated aeodan revealed that the polysaccharide was composed entirely of 1,3 and 1,4 links. Methylation of aeodan revealed the presence of 1,3- and 1,4- linked units, 1,3-linked galactose-2-sulphate, and 1,3-linked galactose-2, 6-disulphate units in the polysaccharide. Partial hydrolysis of aeodan resulted in the isolation and characterisation of 3-O̲-D-galactopyranosyl-D-galactose and 4-O̲-ß-D-galactopyranosyl- D-galactose. A sulphated, methylated polysaccharide, phyllymenan, isolated from the red seaweed Phyllymenia cornea was shown to contain galactose, 2-O̲-methyl-D-galactose, 4-O̲-methyl L- galactose , 6-O̲-methyl -D-galactose, and xylose. The polysaccharide was completely desulphated with methanolic hydrogen chloride. Periodate oxidation of phyllymenan before and after desulphation revealed that removal of the sulphate ester groups had not produced any new adjacent hydroxyl groups. Alkali treatment of phyllymenan revealed that the ester sulphate groups were alkali stable. Methylation studies on phyllymenan revealed the presence of 1,3- and 1,4-linked units, 1,3-linked galactose-2-sulphate, and 1,3-linked galactose- 2,6-disulphate units in the polysaccharide. Partial hydrolysis of phyllymenan revealed the presence or 4-O-̲ß- D-Dgalactopyranosyl- D-galactosc, 4-O-̲ß-D-galactopyranosyl -2-0- methyl-D-galactose, a galactosylgalactose composed of D and L-galactose, and adjacent 6-O̲-methyl- and 2-O̲-methyl-D- galactose units in the polysaccharide.
