- Description: The thesis starts by providing a brief overview of South African ''Coloured" politics from the passing of Ordinance 50 in 1828 to the removal of the Cape Coloured people from the common voter's roll in 1956. It then goes on to discuss in detail the structures instituted by successive Nationalist Governments to serve as an alternative to parliamentary representation for the coloured people, the role of the various coloured political parties within such structures and the latter's gradual adaptation and development, culminating in the inauguration of the Tricameral Parliament in early 1985. The thesis is, on the one hand, a detailed record of coloured political activity following the loss of common roll voting rights in the Cape, focusing on specifically coloured political parties rather than on broader, non-ethnic resistance movements in which many coloured people took part during the same period. This covers the rise and rapid decline of a conservative grouping within the coloured community which sought to foster an exclusively coloured nationalism operating within the Government's policy of parallel development, and attempted to use the Coloured Persons' Representative Council as a means towards achieving the economic, social and political upliftment of the coloured people. It also deals with the important role of the Labour Party after 1966, showing how a moderate resistance movement carne to use the Council as a platform from which to confront the Government's apartheid policies and to render the institutions of parallel development unworkable through noncooperation and boycotting. The second important preoccupation of the thesis concerns the ambiguous and often contradictory attitudes towards the "coloured question" within the National Party itself. This ambivalence, it is argued, not only had much to do with the eventual failure of the Coloured Persons' Representative Council to become a viable substitute for Parliamentary representation acceptable to the majority of coloured people, but was also a primary cause of the National Party split in 1982. It shows too how the collapse of Grand Apartheid had its origins in the failure to incorporate the coloured population within its framework. The thesis is concerned primarily with coloured political developments. When relevant, however, the establishment and development of representative institutions for the Indian people is also dealt with, in so far as this overlaps with issues and events concerning the coloured Council. Finally, the five year period following the dissolution of the Coloured Persons' Representative Council in 1980 and the inauguration of the Tricameral Parliament in 1985 is briefly dealt with in a concluding chapter. This mainly concerns the gradual accommodation reached between the Government and the Labour Party when the latter eventually agreed, conditionally, to take part in the new constitution.

- Description: In recent years, CWIU has been amongst the top six unions involved in strike activity in South Africa. The militancy of our members dates back to the early seventies when it was often impossible to get union recognition without strike action. Over and above plant strikes, the membership of CWIU have a rich history of participating in political mass actions such as the stayaway in the Transvaal in November 1984 against conditions in the schools and townships, and against the LRA Amendments in the late 1980's, and in 1990 and 1991 against VAT. Today, when the bosses are talking about retrenchment, rationalisation, inflation, privatisation, deregulation and productivity, the strike remains one of the most powerful and favoured weapons of the organised labour movement. But not all strikes have been successful. A number of heroic battles fought by workers were defeated. At times workers go on strikes without properly preparing. At other times the issue that they are fighting can be bettter resolved through other avenues of struggle. This booklet is a manual for strike action. We hope that it will assist workers in taking effective and planned action to avoid some of the pitfalls of the past. The booklet outlines some of the key questions that workers should answer before going on strike. It also discusses the most important elements of strike organisation.

- Description: Far away in Canada, young, disabled people 1 are getting together. Erinoak is a centre which helps young people with disabilities. A group of young people decided they wanted to speak for themselves. So they started the Youth Advisory Committee or YAC, as they call it. Upbeat spoke to Jennifer Thompson, a committee member of YAC. Jennifer is 19. 'I joined YAC two years ago,' said Jennifer.'YAC has made a big difference to my life. It helped me to make friends. People in the group gave me support and I got a chance to help others,' she said. YAC meets once a month. We asked Jennifer what they do. 'We organise social events for young people with disabilities. We show movies and help teenagers get together. We also have a newsletter. YAC has helped me to build self-confidence. It taught me what I am able to do. It has made me feel good about myself,' said Jennifer. Jennifer is not the only person who thinks that YAC is great. Annette Symanzik had this to say. 'YAC is a special group for me. It gives me a place where I feel I belong. At YAC I am able to talk to others who have different disabilities. I liked all the events YAC did this year, especially the fun fair, the dance and the panel discussion,' she said. GOING TO SCHOOL In South Africa disabled children attend special schools. But in Canada disabled children go to school with other children. Jennifer attended a local school from the time she started nursery school. 'I had no real difficulties at school,' Jennifer told us. 'The other kids at school were always great. I am glad I was integrated in the school system. But sometimes it is very hard to deal with people who have a negative attitude towards my disability,' she said.

- Description: The gas exchange responses of two cultivars of Hordeum vulgare L., to light, temperature, CO₂ and water stress were investigated in the laboratory. The optimum temperature for net CO₂ assimilation was found to be 25°C and 22.5°C for cv. Clipper and cv. Dayan respectively. Net CO₂ assimilation was reduced at 30°C in cv. Dayan. At low light intensity the highest quantum yield efficiency was 0.051 mol.mol⁻¹ at 30°C for cv. Clipper, and 0.066 mol.mol⁻¹ at 20°C for cv. Dayan. At the same temperature, cv. Clipper had a higher water use efficiency than cv. Dayan, but stomatal conductance for cv. Dayan was higher than cv. Clipper. Stomatal limitation to CO₂ was lowest at the optimum temperature for CO₂ assimilation in both cultivars. Stomata limited CO₂ assimilation in cv. Clipper to a larger degree than in cv. Dayan. Relative stomatal limitation for cv. Clipper at 25°C was 0.280 ± 0.010, and for cv. Dayan at 22.5°C was 0.028 ± 0.011. Short-term exposure to elevated CO₂ concentrations increased CO₂ assimilation in both cultivars, but more so for cv. Clipper. Transpiration rate at elevated CO₂ partial pressures were higher in cv. Dayan than in cv. Clipper. At very high CO₂ (860 μmol.m⁻²s⁻¹) partial pressure water use efficiency in cv. Clipper was higher than cv. Dayan, but at low CO₂ partial pressures water use efficiency in cv. Dayan was higher than cv. Clipper. Water stress reduced the relative leaf water content and net CO₂ assimilation in both cultivars. Cultivar Dayan was more tolerant to water stress, and CO₂ assimilation in this cultivar was less affected by water stress. In both cultivars water stress increased the concentration of chlorophyll a, chlorophyll b, and chlorophyll a+b. The chlorophyll a:b ratio remained relatively constant throughout the stress period. No correlation between relative leaf water content and total carotenoid concentration was observed.

- Description: This thesis explores the major novels of science fiction and fantasy writer, Ursula K. Le Guin: it follows her journey from her first imaginary country, Orsinia, through the inner lands of Earthsea and the outer spaces of the Hainish Ekumen to her Yin utopia in a future California and an Earthsea revisited. In each of these worlds she moves towards an experience of an inner, unified truth which is comparable to the ecstatic experience of the religious mystics and that of which T.S Eliot writes in his Four Quartets. Through her reading of the Taoist sages and the discovery of their perception of Life as a constant and ongoing process rather than as a series of isolated events or states, whether mystical or mundane, these worlds and planets become symbols of a way of life instead of static objects. In her medium, narrative, this way is embodied in the story: the movement towards that moment of enlightenment, which is revealed as the heart, the life-giving centre of each world. It is the home to which each journey returns. "True voyage is return' (The Dispossessed). Owing to this perception of the immanent (w)holiness of life, of the many, different realities, she moves from a serene Taoist equilibrium to an angry feminist rejection of the masculine, dualist, Western civilisation, in which Man has largely been perceived as a creature apart; apart from nature, a guest on this planet, belonging to another world. In her anarchist and feminist utopias she seeks a new spititual home, a less alienated identity for humankind. Despite this apparent "development", at the heart of aU her books there is that same joy in this, mortal life, the search for which she sees as the most essential of aU human pursuits. That, ultimately, is both source and subject of Le Guin's work; and each new world explored is a different manifestation of the joyful Tao, a celebration of life.

- Description: Phenolic compounds are a group of organic chemicals present in the wastewaters of many synthetic industrial processes. Due to their extreme toxicity to man and animals, and deleterious impact on the environment, a range of techniques exist for the effective treatment and disposal of these pollutants. Biological degradation using microbial enzymes presents a valuable alternative to conventional wastewater treatment systems. This research was therefore initiated to investigate the polyphenol oxidase enzyme system and the feasibility of its application for effluent treatment and studies in organic solvents. The enzyme system is widely distributed in nature, with Agaricus bisporus (the common mushroom) being the best known producer. Biochemical investigations of the enzyme system were therefore carried out using this extract. A screening programme was initiated to identify microbial polyphenol oxidase producers which could be cultured in liquid media, thereby enabling the production of large quantities of enzyme in fermentation systems. Extensive growth optimization and enzyme induction and optimization studies were carried out on selected cultures. A number of good producers were isolated, namely a bacterial culture designated AECI culture no. 26, Streptomyces antibioticus, Streptomyces glaucescens and a manipulated strain, Streptomyces lividans (pIJ702). Enzyme production by Agaricus bisporus mycelia was optimized in deep-liquid culture; enzyme extracts showed high phenol removal efficiencies. Streptomyces antibioticus, Streptomyces glaucescens, Streptomyces lividans (pIJ702) and AECI culture no. 26 whole cells were also investigated for phenol-removing ability in simulated phenolic effluents. The use of whole cells reduces enzyme inactivation and instability due to the protection of the enzyme system within the cell. All cultures showed improved removal efficiencies in phenolic growth media. These results strongly suggest their use for phenol removal in continuous systems.

- Description: The synoptic chart encodes climatological and meteorological information in a highly abstract manner. The pupil's level of cognitive development, the nature of the syllabus and the teaching strategies employed by the geography teacher influence the pupil's conceptualisation of information. The synoptic chart is a valuable tool for consolidating the content of the S.A climatology syllabus. Recent research has established that climatology-meteorology, and especially synoptic chart reading and interpretation, is difficult for the concrete thinker. These pupils find difficulty in visualising the weather processes and systems. Provided that they are simple and clear, models are useful teaching devices that integrate and generalise information in a manner that is easily retrievable. The intention of the author is to provide weather type models and other supporting strategies and aids as a means to improve the senior secondary pupil's assimilation of southern African climatological-meteorological information. This model-based approach is tested in the classroom using an action research framework to judge its efficacy. Conclusions are drawn and recommendations are made.

- Description: One of the greatest challenges facing South Africa and the "independent states" of Transkei, Bophuthatswana, Venda and Ciskei over the next decade will be job creation and the development of the skills of the people. This is particularly true of Ciskei with its rapid population growth, unemployment, shortage of skilled manpower and over abundance of unskilled labour. Small business and, in particular, retailing with its relatively low entry requirements, can play a significant role in the creation of jobs. Small business, and small business retailing in particular, suffers, however, from a high failure rate resulting in a waste of financial and human resources which a developing nation like Ciskei can ill afford. The training of people involved in small business retailing is, therefore, of great importance. There is no unanimity of opinion, however, as to what training models or approaches are most appropriate. The purpose of this study was, thus, to design a training model, develop an andragogic training programme for Ciskeian small retailers based upon the model and test it. In accordance with the model developed, the nature of the retailers performance problem was established, the job of the small retailer was analysed, the training needs of retailers were identified, performance standards were set, the course curriculum was developed, training strategies and styles were selected, the necessary training resources were obtained and the training programme was implemented. A pilot training programme was run in 1987 and then the amended programme was run for two years. The results of the training were measured in terms of: -the delegates reaction to the training programme -what the delegates learnt -changes in the business as perceived by regular customers -reaction of the delegates to the training programme one year later -case studies and survival rates Statistically significant positive results were obtained in all aspects evaluated. It can, therefore, be concluded that the andragogic training model for Ciskeian retailers resulted in a positive reaction of delegates to the training, an improvement in the retailer's knowledge of retailing, positive changes in the businesses as perceived by regular customer and improved survival rates of these small retail businesses.

- Description: The historically poorly conserved subtropical transitional thicket (STT) of the Eastern Cape is overutilised by domestic stock and game in the more xeric areas, and has shown no signs of recovery from this grazing pressure. It has been postulated that no regeneration through seeding occurs. This project was undertaken to determine: 1) how much STT has disappeared between 1950 and present, and what the current conservation status is; and 2) whether regeneration of the xeric succulent thicket is taking place through seeding, and if so, where. The study was conducted at the Andries Vosloo Kudu Reserve near Grahamstown. Approximately one-third less STT was mapped in this study, based on 1981 Landsat images, than was mapped in 1950. Approximately 10 % of all remaining STT is conserved. The order Kaffrarian thicket is poorly conserved. Newly germinated seedlings of a wide range of shrub species occurred under the canopies of a wide range of shrubs which served as nurse plants, throughout a gradient of veld condition. Seedlings of Portulacaria afra, the dominant shrub in xeric succulent thicket, were most common. Similarly all saplings recorded in a survey of saplings were associated with bushclumps. One-third of all saplings have the potential to contribute to the spread of bushclumps. Regeneration of xeric succulent thicket through seeding probably does occur, contrary to current ideas. Ptareoxylon obliquum was the most common sapling, despite mature trees now being scarce following earlier heavier utilisation . P. obliquum was also the nurse plant which supported the highest density of newly germinated seedlings. The possible role of P. obliquum in the functioning of xeric succulent thicket is discussed. The confinement of seedlings and saplings to areas under the canopies of trees and shrubs implies that the xeric succulent thicket will not recover rapidly if allowed to rest. Active management techniques will be necessary if rapid recovery is required. Bare areas between bushclumps may no longer be suitable germination habitats because of high Al concentrations. There was no evidence to support the idea that germination and establishment of shrubs in clear areas is linked to episodic climatic events. Dung middens of recently reintroduced black rhinoceros may however aid in germination of seeds and establishment of seedlings under certain climatic conditions. Recommendations for further studies, based on the findings of this project, are made. Possible management techniques aimed at the rapid recovery of this veld are suggested, and management proposals for the Sam Knott Nature Reserve/Andries Vosloo Kudu Reserve complex are made.

- Description: Saline deterioration in the South African public water system has been documented and disposal of brine wastes has been identified as part of the problem. The broad aim of this research programme was to undertake an initial technical study to evaluate the feasibility of integrating algal biotechnology into a disposal function for these wastes. A demonstration of utility in the form of products and waste treatment could produce a beneficiation of saline effluents and provide incentives necessary to deal with the disposal issue. The study attempted to demonstrate a synthesis between the two main thrusts in algal biotechnology that have produced large-scale practical applications - stable, predictable algal production in saline media and the cost effective High Rate Oxidation Ponding (HROP) process for incorporating algal production into a waste treatment function. Tannery organic saline effluents and the biotechnology of Dunaliella salina culture producing β- carotene were chosen as paradigms for the study. 1. The alga was shown to grow in certain tannery effluents producing enhanced biomass yields compared to defined inorganic medium cultivation. The potential for amino acid or protein supplementation of defmed culture media was noted. 2. A reduction in organic load simultaneous with the growth of D.salina was recorded in laboratory-scale simulations of the HROP process. Rates similar to the fresh water HROP equivalent were demonstrated. 3. These results suggested the uptake and storage of organic nitrogen by D.salina. The consequent inhibition of β-carotene accumulation by the organism presented a potentially insurmountable obstacle to the feasibility of β-carotene production in this medium. Uptake and release of organic compounds, previously demonstrated in phytoplankton and other micro-algae, was confirmed in this study for D.salina. The evidence acquired indicated the internalization of both glycine and bovine serum albumin. An ultrastructural study demonstrated mechanisms by which this process might occur. 4. The release of substantial quantities of glycerol was shown. A mechanism whereby D. salina may use this to regulate ammonia availability via control of its associated bacterial population was observed. Glycerol release was identified as presenting an application in treating refractory organic wastes, such as secondary sewage sludges, by elevating C:N ratios. This could demonstrate a significant utility for brine waste impoundments. 5. A multistage production process was proposed to deal with the problem of β-carotene inhibition by separation of the growth and metabolite accumulation functions into separate unit operations. It was shown in this study that the stress of nitrogen deficiency combined with high salinity provides for effectiveβ-carotene accumulation under the conditions of low illumination that pertain in dense cultures. Subjected to these conditions effluent-grown cells show delayed but unimpaired {j-carotene accumulation. 6. A role for the plant hormone abscisic acid in mediating the stress response was demonstrated in D.salina. Fluorescence induction studies suggested the presence of a signalling process forming part of a sensitivity control mechanism. Stress induction of β-carotene accumulation could occur through four clearly defined stages. Potential was identified for using this response as a physiological probe for monitoring and regulating the stress induction process. 7. The multistage processing concept requires effective algal cell separation technology. The use of cross-flow ultrafiltration and diafiltration with a polyethersulfone tubular membrane system was demonstrated as an effective process for the recovery and washing of D. salina. Cell concentrates were produced in a viable form. 8. Process designs incorporating the findings of the research programme are presented demonstrating how effluent and organic waste treatment functions may be combined with the production of D.salina and its products. Application of the multi-stage processing concept to β-carotene production in a defined medium process was identified as offering a potential four-fold yield enhancement. This could have a significant impact on a high cost, marginal algal biotechnology process. Aspects of novelty have been claimed in provisional patents applications. A provisional demonstration of the feasibility of D.salina production in tannery effluent indicates that algal biotechnology may provide a utility for, and hence the beneficiation of saline effluent wastes.

- Description: The case study method was used to trace the therapeutic process of a 23 year old woman, over a period of 12 sessions. The focus of the study was her issue with abandonment which emerged as the central theme in therapy. Hillman's archetypal approach was used as a framework in understanding the process and resolution of her feelings of abandonment. According to Hillman, the therapy process activates the archetypal abandoned child. For a successful therapeutic outcome the process of de-literalisation must occur in order for the patient to move from literal acting out to symbolic containment. Core moments in the therapeutic process were used, together with an interpretation from Hillman's approach, to illustrate the various themes around the issue of abandonment. The present case study illustrates how the theory in area was relevant in practice with this particular case.

- Description: A range of novel ligand systems have been developed in three distinct phases and preliminary studies have been initiated to evaluate their complexation potential. Phase I incorporated the synthesis of single strand ligand systems, which were mainly based on amino acid residues. Techniques have been developed for the attachment of these ligand systems onto, firstly, a styrene monomer, and then later onto a pseudo-styrene linking group, viz. the p-toluoyl group. The linking reactions were based on the formation of amides or esters by the reaction of an acid chloride system with an amine or alcohol. Phase II involved the synthesis of bis-chain ligand systems and their attachment onto the p-toluoyl linking group. A further linking group was also developed at this stage, viz. the xylyl group. In the preparation of phase II ligand systems, use was made of malonic ester and iminodiacetic acid derivatives. Phase III has involved the synthesis of cyclic ligand systems, with skeletons based upon the structures used in phase I and phase II and two crown ether type systems have been prepared.

- Description: This thesis ventures into the relatively neglected world of twentieth century vocal music, via the three song cycles of Oliver Messiaen. The song cycle is a comparatively young genre, generally dated from Beethoven's An die ferne Geliebte or by some, even later to Schubert's Die schone Miillerin. Nevertheless, considerable changes have taken place in the 160 years which separate Messiaen's cycles from those of the 'pioneers' mentioned above. A fuller appreciation of twentieth century cycles is facilitated by observing this evolutionary process and placing the works within an historical and cultural perspective. Such an introduction is provided in part one of this thesis, along with relevant details on the life and interests of Messiaen. The latter information gives insight into the compositions themselves and may satisfy the reader's curiosity on the origin of some of the more unexpected techniques or ideas Messiaen llses. Before embarking on a study of the cycles, it is necessary to look at the highly individual musical language of the composer. Section two undertakes this task in some depth, wherever possible relating the explanations directly to the songs which follow. In order to clarify the text and to simplify the exercise for the reader, numerous musical examples have been used. This contributes to the apparent bulk of this section. The main emphasis of the thesis is the detailed study of the 20 songs contained in Poemes pour Mi, Chants de Terre et de Cief and Harawi. The third section of the thesis deals with this material thoroughly and systematically, dividing it up into musical and extra-musical aspects. The texts are considered in terms of Surrealist, religious, Nature, numerological and, in the case of Harawi, mythological and Peruvian folk symbolism. The relationship of text to music is studied and evelopments highlighted. Musically, the study is further sub-divided into piano part and vocal part. In each case, an extensive exploration of the techniques required of the performer is presented. This makes possible the subsequent categorisation of the songs on the basis of similarities in the musical means. Conclusions reached show a progressive development through the three song cycles in the composer's handling of the text, his treatment of the voice, his use of the piano and his expansion of the voice-piano relationship. This body of solo vocal literature emerges as typical of Oliver Messiaen's compositional style in general and therefore properly representative of the meticulous craftsmanship with which his works are constructed. The detailed analysis of all aspects of the songs contributes original material to scholarship on Messiaen and on song cycles in the twentieth century.

- Description: This study explores the possible influence of twenty children on their 'parents', with a view to better understanding the potential 'multiplier effect' of children regarding environmental responsibility. The criteria employed to study the potential influence included certain of the environmental activities learnt by the children during an Environmental Education programme. The programme was undertaken by the researcher with a Std 4 class from Ryneveld Primêreskool in Graaff-Reinet. An action research approach was adopted and results were analysed qualitatively. Due to the short duration and exploratory nature of the project, these results should be viewed as tentative. Proposals are made for increasing the impact of Environmental Education programmes in peri-urban township communities, and recommendations are put forward to help facilitate related studies in the future.

- Description: This study examines the dynamics of agricultural change amongst traditional African smallholder farmers in Shixini location, Gatyana District, Transkei. This entailed an examination of the historical, regional and local causes of agricultural change and the response of the local community. What became evident was that there had been a gradual decline in agricultural output after the 1930s due to a combination of socio-economic and environmental constraints. Pressure on limited resources and land degradation, a consequence of socio-economic pressures on the African peasantry and agricultural expansion, reduced carrying capacities and soil fertility within the African reserves. Racially discriminatory policies also reduced African access to agricultural markets and forced peasants into migrant labour. The initial response to this agricultural decline was to maintain cultivation and pastoral practices, despite declining output, and rely more heavily on migrant labour. However, massive population ~owth from the mid 1950s onwards stimulated a rapid change in cultivation practices. Rural households found it increasingly difficult to gain access to arable land in river valleys and growing poverty undermined their ability to cultivate fields. In response to these conditions the rural population abandoned their fields and expanded garden cultivation. Garden cultivation was a more intensive method of cultivation which made more efficient use of household resources, maintained long-term yields and had a less detrimental impact on the soil. This study attempts to make a contribution to southern African historiography and historical geography. Since the rise of radical human geography in the 1970s there has been a growing number of political economy studies focusing on capitalist expansion, racially discriminatory state policies and associated class conflicts in South Africa. However, most of these studies have focused on urban communities. The political economy of African rural areas has been sorely neglected by human geographers despite the enormous growth of such studies amongst historians and other social scientists. This study of agricultural change in Shixini location, Transkei adds to the small collection of geographical research on the political economy of African rural areas. It also adds to the large body of historical research by focusing on the recent past, a much less well documented period. The most important component of the study was an examination of the response of the rural community to socio-economic and environmental changes. This brought the often neglected role of human agency within the world political economy into the study. Environmental factors, often neglected by'historians and human geographers, were also brought into the analysis. The examination of such a broad range of factors was facilitated through the use of a wide variety of source material including historical, anthropological and socio-economic literature, official statistics, archival records, aerial photographs and a sample survey
