D. Tech. Fine and Applied Arts / No documented projects exists that can serve as a guide for the establishment of community economic development projects among women in Southern Africa with the aim to economically empower them through the manufacturing of export quality garments in large volumes. The premise for this study was therefore to investigate opportunities that could potentially result in the economic empowerment of women by equipping them with textile-related skills, in a community economic development context, to make apparel that can be exported to first-world countries. The aim of this research was to devise a community empowerment model that would facilitate a participative process that will induce change - from poverty to economic empowerment - through the medium of garment product manufacture and distribution.

Focused procedures which streamline and optimise plant prioritisation and selection in bioprospecting have the potential to save both time and resources. A variety of semiquantitative techniques were assessed for their ability to prioritise ethnomedicinal taxa in the Flora of Southern Africa (FSA) region. These techniques were subsequently expanded upon for application in plant selection for the Novel Drug Development Platform bioprospecting programme. Least squares regression analyses were used to test the hypothesis that ethnomedicinal plant use in southern Africa is strictly random, i.e. no order or family contains significantly more medicinal plants, than any other order or family. This hypothesis was falsified revealing several 'hot' plant orders. The distribution of southern African ethnomedicinal taxa was investigated, and revealed low ethnomedicinal plant usage in the Western Cape and Northern Cape. The historical settlement of Bantu tribes in the eastern regions of southern Africa was one explanation for this discrepancy. Growth forms of ethnomedicinal taxa in 'hot' orders (identified in the regression analysis) were analysed. The results indicated no clear preferences across orders, but rather a preference for particular growth forms in certain orders. With respect to distribution, endemism and Red Data List status of ethnomedicinal taxa, the Western Cape had the greatest proportion of endemics and Namibia had the highest proportion of Red Data Listed ethnomedicinal taxa. With respect to chemotaxonomy, the Asteraceae contained the highest proportion of terpenoids, the Rubiaceae the highest proportion of alkaloids and the Fabaceae the highest proportion of flavonoids. The predictive value of regression analyses was tested against an existing analysis of anti-malarials and the subsequent in vitro bioassays on Plasmodium falciparum. In particular, the ability of these analyses to identify plants with anti plasmodial IC50 values of [less than or equal to] 10 [micro]g/ml was assessed. Most species in 'hot' genera showed comparatively good antiplasmodial activities (IC50 [less than or equal to] 10 [micro]g/ml). Plant candidates were prioritised for screening anti-tuberculosis, anti-diabetes and immune-modulatory compounds, using a weighting system based on; their ethnomedicinal application, chemotaxonomic potential, frequency in ethnomedicinal trade, association with the relative disease, toxicity, Red Data status, indigenous or endemic status, and family selection in ethnomedicine (identified through regression analyses). Other taxa were short-listed due to their presence in biodiversity hotspots where few ethnomedicinal plant use records are documented, and still others were incorporated due to their taxonomic association with efficacious exotic allies. Statistical analyses of the weighting processes employed were not possible in the absence of screening results which are due only in December 2006. The legislation governing bioprospecting in South Africa is discussed and several recommendations are presented to minimise negative impacts on the industry. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

<p>The present healthcare system in South Africa suffers from a number of serious deficiencies. Whilst orthodox bio-medicine is well established in most first world countries, its total introduction and implementation into all communities within South Africa faces many obstacles. The cost of diagnostic techniques, investigative procedures and pharmaceutical products, the availability of competent medical staff in the non-urban areas, and the lack of acceptance of the philosophy and practice of orthodox bio-medicine in rural regions are but some of the factors which conspire against the general application of this orthodox medical paradigm.<br /> <br /> Another problem confronting healthcare and medical practice in South Africa, particularly at this stage of our historical development, is the absolute focus on orthodox bio-medicine, often to the detriment of other medical paradigms that also have advantages to offer. Can the integration of another medical paradigm, such as Unani-Tibb, enhance the practice of orthodox bio-medicine in this country?<br /> <br /> The aim of the thesis was to investigate the possibility of integrating Unani-Tibb with orthodox biomedicine (also termed conventional, Western or allopathic medicine) and assess its potential for improving delivery of an effective, affordable and appropriate healthcare system in South Africa.<br /> <br /> The research questions which the thesis seeks to answer is whether this integration is possible and whether the delivery of healthcare to the South African population can be enhanced. Changes in the provision of medical education are necessary, and occupy a pivotal role in allowing for this integration. Unani-Tibb is a traditional medical system practiced extensively on the Indian sub-continent and in other parts of the world. At present, however, it is minimally practiced in South Africa. Its primary principle is the energetic promotion of health maintenance behaviour and the prevention of disease, through effective application of dietotherapy, pharmacotherapy and other interventions, as well as the empowerment of the patient towards adopting behavioural changes and lifestyle adaptations. One positive aspect of Unani-Tibb is that it has many features in common with both orthodox biomedicine and African Traditional medicine. These commonalities should allow for greater acceptance by orthodox healthcare professionals, as well as the general population. The first part of the study involved the research and conceptualisation required for the production of a series of customized training modules which introduced the theory and practice of Unani-Tibb. A twelve month part-time training programme based on these modules was subsequently conducted with a number of healthcare professionals presently in active practice and with a background of orthodox medical or nursing healthcare. This outcomes-based training programme included a number of specifically designed training activities, such as case studies, practical exercises and assignments. Appropriate evaluations and assessments were pursued in order to measure performance outcomes and attitudes. Questionnaires for assessing the motivation and satisfaction of the participants were also completed. The second part of the study was in the form of a pilot participant research project, in which the participants applied the information from the integrative programme to a number of chronically ill patients who had previously been treated with standard orthodox bio-medical procedures. The parameters derived for clinical efficacy, cost-benefit and improvement in Quality of Life from Unani-Tibb treatment were then compared to equivalent results obtained by orthodox bio-medicine. In all parameters inspected, the integrative training programme compared favourably to orthodox bio-medical practice. Not only was there an improved clinical efficacy, but the cost-benefit was shown to be superior in most indices measured. The Quality of Life comparison, which assessed the patient&rsquo / s total health status, subjective behaviour and attitude, generally favoured the integrative training programme. The thesis serves to suggest that the integration of Unani-Tibb into orthodox bio-medical training in South Africa is a distinct possibility, and could ultimately allow for treatment which is clinically acceptable, cost-effective and which provides an improved Quality of Life for the population as a whole. I suggest that this pilot study be repeated more extensively, thereby allowing for a more confident and objective assessment.</p>

Although grindstones - that is, pairs of stone implements used to grind, pound, pulverise or otherwise process intermediate materials - have been intensively studied by archaeologists in other parts of the world, in southern Africa to date they have received little attention. Despite a near-ubiquitous presence on Middle and Later Stone Age archaeological sites, their primary function in archaeological reconstructions has been as proxies for other behaviours. These include behavioural modernity; gender; particular plant types, such as geophytes/underground storage organs. This doctoral thesis interrogates grindstones with a view not only to establishing specific (rather than proxy) uses in the southern African archaeological record,but also as a means to explore the gathered side of hunter-gatherer lifeways, which have also historically been neglected. It does this by developing a methodological toolkit for grindstone analysis in southern Africa. Comparison of archaeological and historical literature from the southern African Grassland Biome and elsewhere suggests a tension between archaeological accounts which posit geophyte and mineral pigment grinding as a primary purpose for grindstones and ethnohistorical accounts suggesting that grass-processing was a staple of hunter-gatherer life. Finally, a corpus of putative grindstones from the site of Ha Makotoko in western Lesotho is typologically assessed and analysed for plant starches and phytoliths. It emerges that at this site, and in contrast to received wisdom, geophyte grinding was not extensive but by contrast, grass seed processing was practised. This belies models suggesting that C4 grass seeds were unlikely to have contributed to hunter-gatherer diets, and questions interpretations of grass 'bedding' as well as the distinction between 'forager' and 'farmer'. Most importantly, this thesis validates the idea that grindstone study is worthwhile, and should be integrated into wider lithic study in southern Africa as a matter of course.

A brief review of the various models proposed to account for the Bushveld Complex shows that there are two main hypotheses. These are the Multiple Intrusion hypothesis and the In Situ Crystallization hypothesis. The latter also allows for multiple additions to the crystallizing magma, and several variants involving the number of these inputs , their composition, volume and timing have been proposed. To facilitate description and investigation of the study section, the stratigraphic nomenclature of this part of the Rustenberg Layered Suite is revised and clarified. It is proposed that the boundary between the Critical Zone and Main Zone be placed at the base of the Merensky cyclic unit, and thus the whole of the Merensky and Bastard cyclic units are included in the Main Zone. Furthermore, the extremely confused terminology for smaller units within the Merensky and Bastard cyclic units is resolved by discarding the term Reef as a formal term and substituting lithological terms such as Merensky pegmatoid, Merensky pyroxenite, Bastard pyroxenite and Merensky mottled anorthosite etc. It is recommended that the term Reef be retained as an informal term to designate the mineralized horizon which may be mined, regardless of lithology. The term "pegmatoid" is restricted to stratiform or lensoid masses of coarse grained feldspathic pyroxenite or harzburgite which are part of the layered sequence. The transgressive vertical pipe-like, coarse-grained ultramafic "iron-rich bodies are termed "ultramafic pegmatites ". The main features of the Merensky and Bastard cyclic units are the regular chemical and mineralogical changes that occur with respect to stratigraphic height in these units. In the Merensky cyclic unit there is a smooth iron enrichment in the orthopyroxenes upward in the succession and a transition from pyroxenite at the base to mottled anorthosite at the top of the unit. The Bastard cyclic unit is broadly similar to the Merensky cyclic unit. A variety of textures and chemical features are in disequilibrium in some samples but not in others, and great complexity is evident wh en individual samples are studied in detail. The initial ⁸⁷Sr/⁸⁶Sr ratios of plagioclase separates and whole rocks from the study section show a distinct step-like increase in the Merensky cyclic unit to .70806 at the base of the, Merensky cyclic unit to .70806 at the base of the Bastard cyclic unit. In contrast , samples from below the Merensky cyclic unit have a constant initial Sr-isotopic ratio, as do the samples from the Bastard cyclic unit. These isotopic and chemical data, and available published geologic relationships suggest that a major new influx of basic magma occurred after the Footwall unit was deposited and that this mixed with the residual magma in the chamber and then precipitated the Merensky and Bastard cyclic units. The crystal settling theory as outlined by Wager and Brown (1968) fails to account for the chemical and stratigraphic variations observed in the study section. The theory of bottom crystallization, initially proposed by Jackson (1961), more adequately explains the features observed. Applying a model outlined by Irvine (1980a & b), it has been established from chemical data, that the Merensky cyclic unit crystallized from a magma layer with a thickness roughly equivalent to the average thickness of the cyclic unit itself (±10m). A similar exercise on the Bastard unit was not possible. The formation of the Footwall unit is still enigmatic. Infiltration metasomatism and sintering can modify the petrographic and chemical characteristics of rocks and minerals after deposition at the liquidus stage. During the solidification of the crystal mush a separate vapour phase may form in the crystal mush, which could move up through the crystal pile. This process may ultimately be responsible for the generation of potholes and pegmatoidal horizons, such as the Merensky pegmatoid. The upward increase in the initial ⁸⁷Sr/⁸⁶Sr ratio within the Merensky cyclic unit is strong evidence that infiltration metasomatism has played an important part in the generation of the Merensky cyclic unit. This process, coupled with fluid enrichment, may also result in the formation of pegmatoid layers. Sintering appears to have been a common process in the mottled anorthosites of the study section and may have severely reduced the amount of trapped interstitial liquid in these rocks.

M.Sc. (Geography) / In this study the spatial and temporal variation of radio-refractivity over southern Africa is investigated. Climatological data from 8 upper-air stations and 49 surface stations were used and transformed. into values of refractivity to establish a data base of radio refractivity information. The spatial analysis yielded maps of surface refractivity (Ns ) and height corrected surface refractivity (No) for southern Africa. In order to calculate the height correction factors, a radio-climatological classification of southern Africa was drawn: up. These maps are a refinement of the existing maps published by the CSIR. The temporal analysis consisted of graphs of mean monthly and yearly values of various refractivity- (Ns, Delta N, K-factor) and climatological (temperature, vapour pressure) factors for the eight upper-air stations. Some preliminary information about ducting was also obtained from this analysis. A spatial-temporal analysis of limited extent was then performed for one station to obtain an indication of the factors leading to the formation of radio ducts, as well as the actual variation of refractivity with height. Information about the variation of refractivity over southern Africa was thus obtained, with emphasis on macroscale variation as well as preliminary information about ducting conditions.

In the Swaziland lowlands, biological control of the citrus pest red scale, Aonidiella aurantii (Mask), has been consistently unsuccessful although it is successful in middle altitude regions. However, recent cases of resistance to organophosphate insecticides elsewhere in southern Africa, make it important to reconsider biological control of red scale in the lowlands. Should similar resistance be evolved in this region, the pest could be controlled only by natural means together with oils. This account attempts to answer questions about the natural control of a red scale population in the lowlands, by examining data collected between 1972 and 1975. The population was continuously breeding with overlapped generations. It consisted of three sections, on leaves, twigs and fruit, having different rates of reproduction, development and mortality. These sections are considered separately but that on leaves, being relatively unimportant, is largely ignored. The generation mortality is estimated in the sections on twigs and fruit and related to climatic and biotic indices. The causes of seasonal and between-years variation in the sections on twigs and fruit are elucidated. The effectiveness of each kind of natural enemy is examined and the factors affecting natural enemy numbers are investigated. The question of population regulation is discussed. Differences in mean infestation levels in middle altitude and lowland regions are explained in terms of different rates of reproduction and mortality.
