- Description: Xanthomonas campestris pv. zeae was shown to posses a vast range of potential plant cell wall degrading enzymes including at least one protease, a carboxymethylcellulase, pectin lyase, polygalacturonase and a B-endoglucanase. Replicon stability and transfer system efficiencies were determined for a range of oriC, and oriT -tra combinations, and suitable vectors were constructed and identified for insertional inactivation by homologous recombination. Ideal suicide replicons were found to be pACYC184 and p15A, while P, Wand Q group replicons were supported by X campestris pv. zeae. Group P and group N transfer systems were shown to be highly efficient in intra-genus matings between Escherichia coli and X campestris pv. zeae, with the exception of P-tra systems in trans for the delivery of Tn5. Various cloning vectors were tested for stability and mobility. Tn5 was shown to transpose at high frequencies into the genome of the bacterial plant pathogen, and insertion was relatively random. Suitable screening assays were established to allow rapid isolation of mutants with potential virulence or pathogenic deviations, after mutagenesis. Two non-pathogenic mutants were identified, one of which was a putative hrp·, while the other was a leaky virulence. A single mutant showing 40% reduced protease activity was also shown to exhibit reduced virulence indicating a minor role for the protease in pathogenicity. The majority of virulence mutants showed altered growth in different levels of nutritional availability and complexity. Nutritional viability (the ability to acquire and use nutrients at a sufficient rate to grow fast enough to overcome host defences) was shown to be essential for virulence and possibly pathogenicity. Wild-type in-planta behaviour was analysed and growth and spread patterns typical for pathogenic response identified. Chief amongst these was the requirement for a threshold level of cells per leaf area or length, before symptoms could develop. Occlusion of vascular bundles was shown not to be the primary factor in the pathogenicity of X campestris pv. zeae. Threshold levels for lesion development indicate the absence of a diffusable lesion forming element, and possibly the requirement of cell density for induction of certain functions. , KMBT_363

- Description: This thesis examines the use of elements of myth and ritual in the work of Peter Brook, focusing primarily on The Mahabharata ( 1986 ). The argument proposes that Brook uses myth and ritual as an integral part of his search for the culture of links .. This thesis examines the precise functioning of myth and ritual in Brook's theatre, and places his work in relation to the concepts of interculturalism and postmodernism. In so doing, The Mahabharata is seen as a valid and important step in Brook's search for the culture of links. Chapter One formulates broad-based concepts of myth and ritual, and examines their function in society and culture, as well as their role in theatre. Chapter Two offers a brief discussion of the use of elements of myth and ritual in Brook's productions, beginning with King Lear (1962), and ending with 0rghast (1971). The discussion illustrates the multiple functions which myth and ritual serve in Brook's work. Chapter Three examines the trend of interculturalism, placing Brook's work within this franlework. Attention is given to the moral and political issues implicit in interculturalism. The chapter highlights the need for intercultural theatre to be evaluated in terms of artistic criteria, rather than on anthropological or political grounds. Finally, there is a discussion of the work of other intercultural theatre practitioners. Chapter Four examines Brook's Mahabharata. A detailed discussion of the authenticity and visual presentation of Brook's interpretation shows how Brook mediates between the Indian epic and a Western audience An examination of the critical response offers insights into the dangers of insensitive cross-cultural contact.. Chapter Five offers a critical summary of the argument. Brook's search for the culture of links has led him to use elements of myths and rituals of non-Western cultures. In so doing, Brook seeks to bring their living quality to his work, and to forge links between the peoples and cultures of the world.

- Description: Die doel van hierdie studie was om aan te toon hoe 'n linguistiese beskouing van 'n literere teks kan meehelp om tot gefundeerde insigte in 'n teks te kom en om langs hierdie weg die beskuldiging dat literatuurstudie grotendeels 'n 'anything-goes-dissipline' is, te omseil. Om hierdie rede is daar van die standpunt uitgegaan dat kennis oor die presiese aard van die tekslinguistiek kan meehelp in die toepassing daarvan. Dit dien as motivering vir die uitgebreide diachroniese situering van die tekslinguistiek van die eerste hoofstuk. Hier word geredeneer dat die tekslinguistiek iets soos 'n pseudo-literatuurteorie is wat kan meehelp in die lees en interpretasie van en kommentaar oor 'n literere teks. Daar is grotendeels gefokus op die literere benaderings wat die ontwikkeling van die tekslinguistiek voorafgegaan en be'invloed het. Daar was drie hoofstrominge t.o.v. tekstuele benadering, nl. (i) tekssentriese (outonomistiese), (ii) linguistiese (taalsentriese), en (iii) lesersentriese benaderings. Die vemaamste tekssentriese (outonomistiese) benaderings is die Russiese Formalisme, New Criticism en Stilistiek op taalkundige grondslag. In die bespreking van hierdie benaderings is dit tel kens in verband gebring met die bestaande teorie oor die tekslinguistiek ten einde die diachroniese aard van die ontwikkelingsgang daarvan, te karteer. Die vernaan1ste eksponente van die linguistiese (taalsentriese) benaderings is die Strukteralisme, Poststrukturalisme en die Semiotiek. Daar is in hierdie afdeling duidelik aangestip hoe die standaarde van tekstualiteit (De Beaugrande en Dressler, 1981), en spesifiek die standaard kohesie, terug te vind is in hierdie benadering tot teksstudie. Die Resepsie-estetika en Referensiele benadering is bespreek as eksponente van die sg. lesersentriese benadering. Die doel hiervan was om aan te dui hoe intertekstualiteit, kontekstualiteit en informatiwiteit as standaarde van tekstualiteit, in hierdie benadering terug te vind is. Met die diachroniese situering in gedagte, is daar in die tweede deel van Hoofstuk Een oorgegaan tot 'n sinchroniese karakterisering van wat die tekslinguistiek behels. In hierdie hoofstuk is daar voortgegaan met die beredenering dat die term diskoerslinguisliek • n meer akkurate benaming is vir 'n dissipline wat meer as net ' teks' in ag neem. Diskoers kan beskou word as 'n reeks taaluitinge wat 'n taalhandeling vorm. Hoewel diskoerslinguisliek die term tekslinguistiek in hierdie studie vervang, is daar duidelik aangetoon dat dit nie die doel het om aardskuddend veranderend te wees nie. Die werkswyse wat in hierdie studie gevolg is, is steeds die van die tekslinguistiek. Om hierdie rede is hierdie gedeelte van die studie grootliks teoreties, dit bespreek die interdissiplinere aard van tekslinguistiekldiskoerslinguistiek, definieer dit, en identifiseer die studieveld van 'teks'. Hierdie identifisering (sintaktiese eenheid, semantiese eenheid en pragmatiese eenheid) funksioneer breedweg as die hoofuiteensetting van hierdie studie. Tog word daar in hierdie studie aangetoon dat daar verskil word van die De Beaugrande en Dressler-aanname dat daar sewe standaarde van tekstualiteit bestaan, en word dit hier gereduseer tot twee superstandaarde, nl. kohesie en koherensie. Koherensie beskik oor sg. 'voorwilardes', nl. intensionaliteit, aanvaarbaarheid, informatiwiteit, kontekstualiteit en intertekstualiteit. Op hierdie wyse word die meganistiese indeling van die oorspronklike sewe standaarde oorkom. In Hoofstuk Twee word die teorie rondom die superstandaard kohesie toegepas op die Nederlandse teks deur Kristien Hemmerechts, Kerst en andere liefdesverhalen. Hierdie hoofstuk het die implisiete doel om aan te toon hoe 'n suiwer strukturalistiese ondersoek na 'n tekstuele gegewe kan meehelp in die identifisering van bepaalde linguistiese patrone wat, indien gesitueer in 'n pragmatiese milieu, bepaalde betekeniswaarde verkry. Verskeie aspekte rondom die konsep 'kohesie' word hier bespreek, o.a. 'n by trek van sg. storiegrammatika van die liefdesverhaal en sprokie ten einde bepaalde taalpatrone te identifiser wat pragmatiese betekenislading het. Hierbenewens word daar suiwer struktureel met die teks omgegaan met 'n identifisering van bepaalde patrone in die adjektief-aanwending, die gebruik van saakname, verwysing, polisemie, sinonimie, teenoorgesteldheid, antonimie, komplementeerbaarheid, ruimtelike opposisie en hiponimie. 'Hierbenewens word kohesiewe-bindingspatronesoos ellips, semantiese rolle en sg. tematiese kontinuHeit bespreek. Die daaropvolgende hoofstuk is 'n bye en bring van die ge"identi±iseerde talige patrone van Hoofstuk Twee en 'n situering daarvan in 'n pragmatiese raamwerk. Koherensie is die somtotaal van eenheid en betekenis soos wat dit in diskoers ervaar word. Dit het betrekking op dit wat bydra dat 'n teks vir taalgebruikers sin maak en samehang vertoon. Aangesien koherensie grootliks steun op die pragmatiek, is die fokus van hierdie afdeling van die studie grootliks pragmaties en word daar aangedui hoe die bestaan van bepaalde koordinate, 'n beginsel van samewerking en 'n spraakhandelingsteorie kan bydra tot gefundeerde insigte in die onderhawige teks.

- Description: This study focuses on South African Environmefltal policy; in particular its policies regarding hazardous waste. These policies are addressed within the framework of a case study which serves as basis to critically evaluate government environmental policies both past and present. The thesis examines South African environmental policy against the backdrop of competing schools of thought regarding the relationship between growth and development on the one hand and long term environmental security on the other. Development strategies such as Sustainable Development and the government's Growth, Employment and Redistribution as well as philosophies such as Deep Ecology will be discussed. The thesis argues that Non-Governmental Organisations are the holders of a real environmental ethic and thus their role in preventing environmental degradation is of critical importance. Furthermore, it is imperative that this ethic be disseminated across society if South Africa is to successfully pursue sound environmental policies. This argument is pursued by way of a case study, Thor Chemicals: a company responsible for the running of the largest mercury recovery facility in the world. This plant, which operated in Cato Ridge, KwaZulu-Natal, has been the source of much controversy since it was found that many of its employees and ex-employees were suffering from severe mercury poisoning resulting in two fatalities. The company was also involved in the importation of hazardous wastes as well as the pollution of the surrounding environment. Thor is currently the subject of inquiry by the government-appointed Davis Commission. It is pointed out that ill the past South Africa held no real environmental ethic and environmental degradation ensued as a result. The presented thesis argues that, despite assurances to the contrary, the present government is also without a true environmental ethic that will be effective in preventing future degradation.

- Description: The study period saw a significant increase in the urbanisation of whites and blacks in Port Elizabeth induced by droughts and coercive legislation, but also by burgeoning industrialisation. Industry had been given great stimulus by World War 1 and maintained by protectionist legislation in the 1920s which the local state and industrialists came to endorse. The ethos of the town was overwhelmingly British in terms of the population, the composition of the local council, business interests and the prevailing culture. Whites formed the largest component of the population in Port Elizabeth during the inter-war years. The majority of white women lived in the North End, the industrial hub and a major working class area of the city. Although the provision of housing was initially neglected, economic and subeconomic housing in the 1930s helped to create both racial separation and a sense of community between sectors of the working class. Yet, white working class women did not form a homogenous group, but rather consisted of different ethnic groups, occupations and classes. The Afrikaans speaking sector, formed a significant component of the industrial labour force especially in the leather, food and beverage and clothing industries. In a centre where white labour was favoured and marketed as an advantage to outside investors, they rapidly displaced coloured women. The female workforce was basically young, underpaid (especially in comparison to wages on the Rand) and temporary. While white women were still in evidence in other occupations such as domestic work and in the informal sector, their numbers here steadily diminished as both racial segregation and municipal regulation, were implemented. Against a background of chaotic social conditions, large slum areas and the spread of infectious diseases, the local council did much to improve health services particularly for women and children. Poor relief instituted in 1919 was, however, less forthcoming and female - headed households were often left to rely on the services of local welfare organisations. The extended family, however, was the norm affording support against atomization. Although pressurised by social ills throughout the period, the family was increasingly buttressed by state assistance. Prevailing morality was likewise actively constructed in terms of legislative repression and racial division. This often lead to social aberrations such as infanticide which was only reduced by the increase of state assistance and, in the longer term, social mobility of the whites.

- Description: This mini thesis proposes that the Dance Factory in Ne'Ntown, Johannesburg, is a site of resistance. Its source and motivation are the personal, artistic and socio-poIiticaI sites ofresistance to mainstream forms of dance with nationalistic tendencies and to dominant ideological hegemonies that enforced apartheid or nationalism. Therefore, these sites or resistance are examined prior to and after the democratisation of South African culture. An analysis of the dances choreographed in this period of transition and changing hegemonies reveal shifts of resistance. These are traced within the development of the Dance Factory. Chapter one explores the notion of resistance as a form of power and the notion of site, where the operations of power evoke resistance. Three sites of resistance within South African dance culture are identified and examined. These are the Dance Factory, the artistic site of dance and the site of the dancing body. The chapter reveals the development of these sites in a changed culture and notes a re-orientation of resistance within dance, namely Afro-fusion, and the subsequent development and emergence of 'alternative' sites of resistance. These reveal new expressionistic tendencies, body politics and the feminist strategies of 'new poetics' and 'ecriture feminine'. The codified mainstream forms of dance, subject to nationalistic strategies of dassicism and its inherent Iogocentricity are challenged and destabilised by the emergence of these altemative resistant forms of dance. Chapter two examines the artistic policies of the Nationalist Govemment, the African National Congress and the Dance Factory from 1983-1997. It notes the effects of the changes in the artistic policies on sites of resistance in dance, performed at the Dance Factory. The chapter desaibes the development of the Dance Factory, its policies of diversification as a strategy of resistance, its promotion of praxis, its resistance to nationalism and the ramifications thereof. It also explores the effects of a governmentalisation of culture and the role of the organic intellectual within the Dance Factory. An analysis of the alternative dance work 'Torso-Tongue" in chapter three furthers the argument that the Dance Factory maintains and encourages the changing sites of resistance in dance. This analysis demonstrates the resistant aspects of dance as discussed in chapter one and thereby confirms the aims and missions of the Dance Factory. The thesis examines the role of the Dance Factory as it develops, nurtures and responds to the shifts in resistance and changes in culture and dance. Most importantly the thesis exposes the resistance to and the effects of an imposition of a nationalistic ideology on dance. The resultant resistance to this form of domination is explored in dance within the site of the Dance Factory, thus supporting the premise that the Dance Factory is a site of resistance.

- Description: This mini thesis proposes that the Dance Factory in Ne'Ntown, Johannesburg, is a site of resistance. Its source and motivation are the personal, artistic and socio-poIiticaI sites ofresistance to mainstream forms of dance with nationalistic tendencies and to dominant ideological hegemonies that enforced apartheid or nationalism. Therefore, these sites or resistance are examined prior to and after the democratisation of South African culture. An analysis of the dances choreographed in this period of transition and changing hegemonies reveal shifts of resistance. These are traced within the development of the Dance Factory. Chapter one explores the notion of resistance as a form of power and the notion of site, where the operations of power evoke resistance. Three sites of resistance within South African dance culture are identified and examined. These are the Dance Factory, the artistic site of dance and the site of the dancing body. The chapter reveals the development of these sites in a changed culture and notes a re-orientation of resistance within dance, namely Afro-fusion, and the subsequent development and emergence of 'alternative' sites of resistance. These reveal new expressionistic tendencies, body politics and the feminist strategies of 'new poetics' and 'ecriture feminine'. The codified mainstream forms of dance, subject to nationalistic strategies of dassicism and its inherent Iogocentricity are challenged and destabilised by the emergence of these altemative resistant forms of dance.

- Description: This thesis sets out to critically examine Guidano's model of psychopathology in eating-disordered individuals . The literature review highlights the diverse etiological approaches that have been taken in understanding eating disorders. Guidano's model is presented as an alternative to traditional approaches . It is a developmental, unitary model of psychopathology, conceptualised within a systems/process-oriented approach to organised complexity. Within a qualitative framework, case study methodology is utilised to test the viability and limitations of Guidano's model. Four in-depth case histories are presented which offer appropriate material for the testing of the model. The data is analysed using the reading guide method and presented in terms of the four features of Guidano's model: (1) dysfunctional patterns of attachment; (2) sense of self; (3) major themes on systemic coherence; (4) common coping strategies. The findings of the research support Guidano's model of psychopathology in eating-disordered individuals. The findings are: (1) attachment styles are ambiguous, "intrusive, and enmeshed; participants experience a disappointment in the preferential attachment relationship; (2) that participants' sense of self is blurred and wavering; (3) the major theme on systemic coherence is the oscillation between seeking and avoiding intimacy; (4) common coping strategies are: the seeking of supportive intimacy with minimal self-exposure; withdrawal into the self; perfectionism; the development of an eating disorder; continuous thoughts about food, eating, and weight which prevents participants from becoming aware of the real issues confronting them. An evaluation of Guidano's model in terms of its specific contribution to knowledge and research on the role of father in child and adolescent psychopathology, as well as how father effects evidence in eating disorders, demonstrates the model's value as an explanatory tool and raises implications for future treatment, theory, and research practices of eating-disordered individuals.

- Description: This thesis describes preliminary two- and three-dimensional modelling of mass and heat transport of hot, molten magma in crustal intrusions and of the associated thermally induced flow of groundwater contained in the surrounding country rock. The aim of such modelling is to create a tool with which to predict the location of mineral deposits formed by the transport and subsequent precipitation of minerals dissolved in the convecting groundwater. The momentum equations (Navier-Stokes equations), continuity equation and energy equation are used in conjunction with specially constructed density and viscosity relationships to govern the mass and heat transport processes of magma and groundwater. Finite element methods are used to solve the equations numerically for some simple model geometries. These methods are implemented by a commercial computer software code which is manipulated with a control program constructed by the author for the purpose. The models are of simple two- or three-dimensional geometries which all have an enclosed magma chamber surrounded completely by a shell of country rock through which groundwater is free to move. Modelling begins immediately after the intrusive event when the magma (in most cases rhyolitic) is at its greatest temperature. Heat is allowed to flow from the magma into the country rock causing thermal convection of the groundwater contained therein. The effect of the country rock as a porous medium on the flow of groundwater is modelled by including a distributed resistance term in the momentum equation. The computer code that controls the modelling is such that adaptions made to the models to represent real physical intrusive systems are trivial. Results of the research at this stage allow approximate prediction of the location of mineral deposits. Enhanced predictions can be made by effecting improvements to the models such as a more detailed representation of chemical processes, adaption of the computer code to allow multiple injections of magma and the modelling of frozen magma as a porous medium which admits the flow of groundwater.

- Description: The objectives of the study were to determine whether or not behaviour could be used to predict spawning in Amphiprion akallopisos, and to document the behaviour of this species under various environmental conditions in captivity. The spawning behaviour of A. akallopisos was studied and quantified. Three behaviour patterns - belly touching, nest cleaning by the female and mutual nest cleaning (by the male and the female) were identified as predictors for spawning. The reproductive behaviour of A.akallopisos under three photoperiods was investigated. The photoperiods were: 14L:10D, 10hr15minL:13hr45minD and a natural photoperiod cycle condensed into three months. A. akallopisos maintained under 14 L:10D exhibited a significantly higher frequency and duration of chasing, nest cleaning and total interaction compared to fish kept under 10hr15minL:13hr45minD. A photoperiod of 14L:10D was selected for further studies. As manipulation of photoperiod did not induce spawning, GnRHa was administered to the fish in the diet at levels of 10, 20, 40 and 80 μg/kg BW. Control groups were fed untreated food. None of the dosages were successful in inducing spawning, or spawning behaviour in A. akallopisos. It is possible that the method of hormone application was not suitable for this species. It is also possible that behaviour may regulate blood hormone levels as opposed to endocrine status influencing behaviour. In the third trial, A. akallopisos was maintained with, and without sea anemones in order to determine whether or not anemone hosts are necessary for spawning. The presence of anemones did not induce spawning and A. akallopisos kept without anemones exhibited significantly more interactive behaviour than fish kept with hosts. Spawning of A. akallopisos at a later date without anemones suggests that anemones are not necessary for spawning in A. akallopisos. Light intensity was investigated as a cue for spawning. The reproductive behaviour of A. akallopisos was then studied under light intensities of 4.16 x 10¹⁵ quanta.sec⁻¹.cm⁻², 8.85 x 10¹⁵ quanta.sec⁻¹.cm⁻² and this intensity plus natural light. Spawning occurred mainly under 8.85 x 10¹⁵ quanta.sec⁻¹.cm⁻². Fish maintained under this light intensity exhibited significantly more of nest cleaning behaviour in terms of frequency and duration than fish maintained under low light intensity. A minimum light intensity of 8.85 x 10¹⁵ quanta. sec⁻¹.cm⁻² is recommended for conditioning of this species. This study can be of practical relevance to hatchery managers who can use the methods developed and record predictors for spawning in A. akallopisos and other Amphiprion species. In this way imminence of spawning may be estimated. Most importantly, the study also has academic merit as little work has been undertaken in this field. Although the observational method used in this study was adequate for the purposes of the investigation, future work of this nature should incorporate other methods of documenting gonadal development such as gonadal staging and GSI in order to obtain more conclusive results.

- Description: This study discusses the extent to which Charles Sturridge's Where Angels Fear to Tread, Merchant Ivory's Howards End, and David Lean's A Passage to India have aimed at, and succeeded in, exploring the thematic concerns of E.M. Forster's novels. A brief introductory chapter explains the motivation behind this research, and the choice of critical methodologies used. It concludes with an outline of some of the problems confronting film-makers wishing to explore the concerns of novels. The first chapter, which is devoted to Where Angels Fear to Tread, reveals that while Sturridge is "faithful" to Forster's novel at a superficial level, basing most of his scenes on, and taking most of his dialogue directly from, the text, he does not explore Forster's themes. The facility with which film tells stories proves to be a treacherous trap for Sturridge. His version of Where Angels Fear to Tread is totally vacuous because he failed to develop anything beyond the story -- Forster's "tapeworm" of time (Aspects of the NoyeI41). The causality that Forster calls plot seemed beyond Sturridge's comprehension, leaving his film little more than an endless progression of "and then[s]" (Forster, Aspects 87). Characters are not given their full weight; symbols and leitmotifs are overlooked; the allegorical elements he did recognize, he failed to understand, and thus misplaced, so that the epiphanic moments of the novel are lost. There is no possibility of thematic concerns emerging from a film in which plot, characterization, symbol and rhythm are ignored. Sturridge's apparent inability to understand his source is in stark contrast to Merchant Ivory's sensitivity to Howards End, and their evident familiarity with literary criticism on the work. Chapter two explores the way in which their adaptation smooths out putative flaws in characterization and plot, and uses filmic rhythm and camera work to suggest comments made by the novel's narrator. Almost wholly successful in developing the novel's themes, Merchant Ivory's Howards End does not, however, successfully explore the spiritual dimensions of Forster's novel. Film is a medium capable of great subtlety, but its strength lies in its ability to capture the seen; the unseen tends to evade its grasp. It is in dealing with the unseen that Lean's A Passage to India misses greatness, for in virtually every other respect his version of Forster's masterpiece is superb. Chapter three explores Lean's creative and flexible approach to adaptation, his acute sensitivity to the differing demands of film and novel, and his confident technical mastery. It also explores, however, the emptiness at the heart of his film, an emptiness that is the result of his trivialization of the spiritual concerns of Forster's novel.

- Description: The Precambrian rocks of KwaZulu-Natal comprise the Archaean granite-greenstone remnants of . the Kaapvaal craton and Late Archaean volcanics and sediments of the supracratonic Pongola Supergroup. These Archaean rocks have been intruded by numerous mafic/ultramafic complexes and voluminous granitoid intrusives of various ages. To the south, the basement rocks are represented by the Mid- to Late-Proterozoic Natal Metamorphic Province (NMP). The NMP comprises three discontinuity-bound tectonostratigraphic terranes. These are, from north to south, the Tugela, Mzumbe and Margate Terranes. The Tugela Terrane has been interpreted as an ophiolite suite that was thrust northwards onto the stable Archaean craton as four nappe structures. Continued thrusting resulted in the two southern terranes being thrust northwards over each other, resulting in numerous sinistral transcurrent shear zones and mylonite belts. The greenschist facies Tugela terrane has been intruded by mafic-ultramafic complexes, alpine serpentinites, plagiogranites and a number of alkaline to peralkaline granitoids. The Mzumbe and Margate Terranes comprise arc-related, felsic to mafic supracrustal gneisses and metasediments that were intruded by syn-, late- and post-tectonic granitoids. Mineralisation in the granite-greenstones consists of structurally-hosted lode-gold deposits. These deposits have many characteristics in common with lode-gold deposits found in other granitegreenstone terranes throughout the world. The Nondweni greenstones also contain volcanogenicrelated massive sulphide deposits. The Pongola Supergroup is host to lode-gold mineralisation and placer gold mineralisation. These placer deposits have been correlated with deposits found in the similarly-aged Witwatersrand Basin in an adjacent part of the craton. The metallogeny of the NMP can be described in relation to the various stages in the tectonic evolution of the belt. The initial, rifting and extension-related stage was characterised by arcrelated magmatism and volcanic arc activity. Alkali basalt magmatism due to hot-spot activity in the oceanic basin in which the Tugela Terrane initially accumulated, produced magmatic segregation deposits, while volcanic-arc activity is responsible for the submarine-exhalative massive sulphide mineralisation. All the mineralisation within the NMP is structurally-related. These thrusts and shear zones were developed during obduction and thrusting during the NMP event, and created the paths necessary for the migration of mineralising fluids. Alpine-type ophiolite deposits were also emplaced along these zones. Epigenetic, shear zone-hosted gold mineralisation occurs in the Tugela and Mzumbe Terranes. Mineralisation occurs within quartz veins and is also disseminated within the sheared host-rocks. The Mzumbe Terrane also contains small showings of massive sulphide deposits that were related to volcanogenic exhalative processes during the formation of this terrane. Potential for finding further mineralisation of this type appears to be good. The massive sulphide deposits formed early in the evolution of the belt, and were deformed and metamorphosed during the later accretionary processes. The southernmost Margate Terrane is characterised by a lack of metalliferous mineralisation, but hosts the extensive, and economically important, limestone deposits of the Marble Delta. The recently discovered spodumene-rich pegmatite deposits of this terrane may also be considered for exploitation. Post-collisional magmatism and metamorphism resulted in extensive rapakivi-type granite/charnockite plutons

These deposits have many characteristics in common with lode-gold deposits found in other granitegreenstone terranes throughout the world. The Nondweni greenstones also contain volcanogenicrelated massive sulphide deposits. The Pongola Supergroup is host to lode-gold mineralisation and placer gold mineralisation. These placer deposits have been correlated with deposits found in the similarly-aged Witwatersrand Basin in an adjacent part of the craton. The metallogeny of the NMP can be described in relation to the various stages in the tectonic evolution of the belt. The initial, rifting and extension-related stage was characterised by arcrelated magmatism and volcanic arc activity. Alkali basalt magmatism due to hot-spot activity in the oceanic basin in which the Tugela Terrane initially accumulated, produced magmatic segregation deposits, while volcanic-arc activity is responsible for the submarine-exhalative massive sulphide mineralisation. All the mineralisation within the NMP is structurally-related. These thrusts and shear zones were developed during obduction and thrusting during the NMP event, and created the paths necessary for the migration of mineralising fluids. Alpine-type ophiolite deposits were also emplaced along these zones. Epigenetic, shear zone-hosted gold mineralisation occurs in the Tugela and Mzumbe Terranes. Mineralisation occurs within quartz veins and is also disseminated within the sheared host-rocks. The Mzumbe Terrane also contains small showings of massive sulphide deposits that were related to volcanogenic exhalative processes during the formation of this terrane. Potential for finding further mineralisation of this type appears to be good. The massive sulphide deposits formed early in the evolution of the belt, and were deformed and metamorphosed during the later accretionary processes. The southernmost Margate Terrane is characterised by a lack of metalliferous mineralisation, but hosts the extensive, and economically important, limestone deposits of the Marble Delta. The recently discovered spodumene-rich pegmatite deposits of this terrane may also be considered for exploitation. Post-collisional magmatism and metamorphism resulted in extensive rapakivi-type granite/charnockite plutons

- Description: The purpose of this research project was to explore the English communicative competency of management and supervisory level employees within the South Mrican hospitality industry. The Pro lit English Written Assessment, a competency-based assessment tool, was used to establish a relatively objective measure of the English communicative competency of nineteen managers and supervisors. Thereafter thirteen of these respondents were interviewed to determine their perceptions of their English communicative competency and the impact thereof on their work situation, as well as their perceptions of their learning needs and recommendations for intervention. The researcher selected a multi-method approach to the investigation and sought both quantitative and qualitative data. The assessment revealed that the English reading and writing ability of the respondents is distinctly lower than their recorded education level and inadequate in relation to the tasks they are expected to perform at work. The interviews indicated that the respondents are not aware of their lack of English communicative competency or the implications thereof. However, the respondents expressed important insights into the factors that should be taken into account when planning an educational intervention III an organization. These included the need to incorporate English second language learning principles, to treat the learner as an individual, to involve the learner in the decision-making process, to consider the practical concerns of the learner and to ensure that the programme content is appropriate. Recommendations for human resource practices and research in the hospitality industry are presented.

- Description: The three major species Lethrinops ''pinkhead'', Otopharynx argyrosoma "red" and Copadichromis. cf virginalis which used to dominate the catches (by weight) of Lake Malombe in the past decade were investigated. In order to make rational recommendations regarding size and boundary of the existing sanctuary area (lightly fished), distribution and abundance, population structure and reproductive biology of the three species were related to habitat types of the southern part of the lake (south western side and south eastern side). Analysis of catch composition showed that species richness was higher in the south eastern side than in the south western side of the lake. Rare species such as Labeo mesops and Opsaridium microiepis were observed in the south eastern side and there was visual absence of such species in the south western side of the lake. The overall fish abundance was significantly greater in the south eastern side than in the south western side of the lake. In the south eastern side, the catch per unit effort (CPUE) was twice that of the south western side (P< 0.05). Seasonal fluctuations in CPUE were also prominent, with the highest peak occurring during September-October period. However, there was an indication of weak relationship among CPUE, phytoplankton biomass, temperature and water depth. The length-weight relationships revealed that growth of the three species closely followed the cubic law for isometric growth in both sides of the lake. Differences in regression coefficients between sides were not significant (ttest, P>0.05). The length-frequency distribution analysis revealed that the three species had the same growth rate regardless of habitat type. However, females grew faster than males. An investigation of reproductive biology showed that the three species have low fecundity and they are asynchronous spawners, with a breeding peak during August and September period. Furthermore, the length-fecundity relationships for L. ''pinkhead'', and 0. argyrosoma "red" indicated that fecundity was more closely related to length in the south eastern side than in the south western side. Based on the above characteristics of L. ''pinkhead'', 0. argyrosoma "red" and C. cf virginalis, and the substrate types, it was strongly suggested that the existing sanctuary (lightly fished) in the south eastern side of the lake could immediately be enlarged to conserve the fish stocks, favourable substratum and aquatic animals that may be of tourists concern.

- Description: The Addo Elephant National Park (AENP) is the only existing national park situated in succulent thicket. This unique veld type is endemic to the Eastern Cape, and forms an important centre of endemism for small succulents and geophytes which comprise the subdominant component of the vegetation. It is regarded as the most threatened vegetation type in the Eastern Cape, as much of it has been severely degraded by farming activities and its rate of regeneration is very low. Thus the AENP represents an important sanctuary for certain species. However, large herbivores, particularly elephants, pose a further threat to the vegetation, and areas from which elephants have been excluded in the park (botanical reserves) have been shown to be more speciesrich than the surrounding vegetation. Most elephant-impact studies have focussed on the large shrub component of the vegetation, and only preliminary studies have been done in AENP to date. As the elephant population continues to grow, there is pressure to utilise the botanical reserves to increase the amount of available grazing. It is thus important that the botanical reserve system be highly effective and efficient in terms of area. Existing botanical reserves were established ad hoc and are therefore not necessarily optimal in this regard. An iterative reserve-selection algorithm was used to maximise plant species conservation in the most efficient area.

- Description: International peacekeeping has gained a high profile in international relations and more so, in the post cold war era. The profound increase in the occurrence of civil wars globally and the consequent high demand for the UN to intervene has compelled the world body to delegate its peacekeeping powers to regional organisations. SADC is one of many regional organisations around the world which are faced with the challenge of developing peacekeeping capacities to resolve local conflicts. This thesis endeavours to investigate the prospects of peacekeeping in Southern Africa with specific reference to the involvement of South Africa as a regional power with the wherewithal to play a leadership role in this regard. This is done within the theoretical framework that is provided by the Realist school of thought in international relations. Furthermore, the concept of national interest as defined by Realism will be utilised to explain why countries in Southern Africa in general and South Africa in particular become involved in regional peacekeeping initiatives. The issue of whether the Republic should be involved and how much it should be involved has provoked an intense debate within the country. This debate will therefore be instructive in understanding the dynamics that influence the country's foreign policy behaviour towards the region in relation to playing a leadership role in regional peacekeeping initiatives. The central issue implicit in the debate is the fact that most of the SADC member states that are expected to contribute towards these initiatives have weak economies. This economic weakness in turn leads to the thorny issue of having to seek foreign assistance from western countries from which the region is trying to gain greater independence. This presents the region with a paradox because foreign assistance has serious implications for the SADC countries' sovereignty. It is in this context therefore, that this thesis examines economic development in individual SADC countries and in the region as a whole to establish whether they are in a position to develop a sustainable regional peacekeeping capacity. The contention of the thesis is that economic development is closely related to peacekeeping because without a sound economic base Southern Africa or any other region for that matter, will not be able to develop a viable peacekeeping capacity. On the other hand, keeping the peace in the region is itself important for economic development because it is only in a peaceful environment that economic development can take root.

- Description: Multi-standard classrooms are a distinctive feature of many South African farm schools. This study adopts an ethnographic approach in order to explore how classroom life in one particular Eastern Cape multistandard farm school classroom is shaped by a set of circumstances which influence the nature of teaching and learning in that classroom. The research focuses on the extent to which the difficulties associated with teaching a multi-standard class dictate the teacher's approach to lesson planning and style of teaching and how the resultant pattern of interaction influences language learning within a second language context. Data from a variety of sources, obtained primarily through classroom observations, interviews and questionnaires, is presented. Findings tend to indicate that the demands made on the teachers and pupils in terms of large, multi-standard classes, second language medium of instruction and lack of teaching aids, encourages the use of rote learning techniques which are not conducive to language learning. The pattern of interaction that predominates is a teacher-led series of questions and prompts followed by a chorus response from the pupils. This pattern tends to undermine the communicative aspects of language learning by reducing natural interaction and results in pupil passivity as language learners.

- Description: This project attempts to articulate an understanding of the worlds of selected subjects suffering from schizophrenia, through their dreams. It proceeds from the implicit question of whether or not schizophrenic dreams reflect the schizophrenic worlds as literature defines, and tries to address some of the dream features which reflect the schizophrenic world. Five psychiatric inpatients suffering from schizophrenia were selected. The data gathered included the subjects' dreams and subsequent interviews for the purpose of clarification of the dreams. A phenomenological-hermeneutic methodology was deemed to be appropriate as it gave access to the richness of the dream experiences as well as the following dialogue between the data and literature. The results indicate that the subjects' dream worlds bear evidence to a fragmented state of ego which is to be expected to be found in schizophrenia. On the other hand some of these subjects' dreams also point to evolving health that is present in their world, at least on an intrapsychic level.

- Description: Carapace length, as the best measure of N. marionis body size, is precisely defined. It is shown that N. marionis is a partially protandric hermaphrodite. N. marionis appear to hatch just before April each year, with a little hatching persisting until May. The vast majority of juveniles develop into males. The majority of males transmutate into females in their third year. By April/May the transmutation is probably complete. Reproduction can occur before all male secondary characteristics have been lost. A small minority of individuals develop directly into females without passing through a male phase. At least some of these females can be initially recognized after they have developed mature ovaries by the presence of appendices internae on their first pleopods, a male copulatory structure which all juvenile N. marionis possess. Too few gravid females were recovered to make any statement on whether spawning can occur before this structure is lost. Such females may lose their first pleopod appendices internae in one moult, possibly just before spawning, which may be in late April/early May. Such individuals seem to mature into ovigerous females at a slightly smaller carapace length than do the majority of females which have had a male-phase past. A few females which have passed through a male phase seem to begin developing ovaries at about this small carapace length as well. Once the appendices internae have been lost there appears to be no way of identifying any given female's past life-history. It would seem that during the first year of life N. marionis survive in undetected localities, moult into juveniles, and then settle amongst the benthos from the plankton. Diurnal vertical migration then occurs up to an unknown larger size. It is not known whether the larvae are initially planktonic or not. It is possible that settling of small N. marionis onto the benthos only begins after November. Whether the appendices masculinae of some males only begin growing after they have settled Abstract XIX onto the benthos is unknown, but for the majority at least this begins whilst they are planktonic juveniles. Individuals older than five years are undetectable using samples of the sizes analyzed in this thesis, but they may well persist until quite an advanced age. Niche separation between smaller and larger N. marionis individuals may occur. Diel vertical migration may occur to some extent amongst large N. marionis. Itinerant euphausiids may contribute substantially to the maintenance of top predator populations at the archipelago, either through direct predation by those predators or via predation by N. marionis, which in turn are consumed by those predators. N. marionis itself is an opportunistic feeder, although the majority of its prey seem to be suspension feeders, both benthic and pelagic. In multisample situations, ageing of N. marionis cohorts is made less subjective if one utilizes the phenomenon of synchronized sexual inversion. The von Bertalanffy growth parameters for N. marionis are tentatively identified as k = 0.2353/year, L_ = 12.69mm, to = -0.2828 years and WW_ = 2.03g. The programme FiSAT is discussed, having been found to be extremely useful, but having also been found to have certain faults. Various hypotheses are proposed and are put forward as suggestions for future studies.

Diurnal vertical migration then occurs up to an unknown larger size. It is not known whether the larvae are initially planktonic or not. It is possible that settling of small N. marionis onto the benthos only begins after November. Whether the appendices masculinae of some males only begin growing after they have settled Abstract XIX onto the benthos is unknown, but for the majority at least this begins whilst they are planktonic juveniles. Individuals older than five years are undetectable using samples of the sizes analyzed in this thesis, but they may well persist until quite an advanced age. Niche separation between smaller and larger N. marionis individuals may occur. Diel vertical migration may occur to some extent amongst large N. marionis. Itinerant euphausiids may contribute substantially to the maintenance of top predator populations at the archipelago, either through direct predation by those predators or via predation by N. marionis, which in turn are consumed by those predators. N. marionis itself is an opportunistic feeder, although the majority of its prey seem to be suspension feeders, both benthic and pelagic. In multisample situations, ageing of N. marionis cohorts is made less subjective if one utilizes the phenomenon of synchronized sexual inversion. The von Bertalanffy growth parameters for N. marionis are tentatively identified as k = 0.2353/year, L_ = 12.69mm, to = -0.2828 years and WW_ = 2.03g. The programme FiSAT is discussed, having been found to be extremely useful, but having also been found to have certain faults. Various hypotheses are proposed and are put forward as suggestions for future studies.

- Description: The title, "'n Intertekstuele studie: Die werfbobbejaan van Alexander Strachan", refers to an analysis of the way in which intertextual processes generate meaning in this text. It is analysed with specific regard to the way in which it enters into signifying and detennining relationships with other texts, notably texts by the same author. A significant part of the intertexts that are reassembled, refined, restated, amplified, contradicted or diffused throughout Die werfbobbejaan are located in other works in the Strachan oeuvre: n Wereld sonder grense (1984) and Die jakkalsjagter (1990). These three texts are related as a triptych of intertextual association, and the boundaries between them are not hermetically sealed. Intertextual activity in Die werfbobbejaan involves an intricate network of interfigural relationships. The identities of numerous characters in the text start to coincide with those of other characters to which they are linked intertextually. Characters travel across the boundaries supposedly separating "different" texts. The doubling and displacing of characters alert us to the fact that the text is not fixed within stable boundaries. Codes, scenes, snippets of dialogue and even moods also penetrate the boundaries between "different" texts and recur in the form of mirror images or ghostly transformations of themselves. These intertextual patterns mobilise an active reading process and unify the act of reading with that of writing in "a single signifying process" (Barthes 1979: 79). The narrator in Die werfbobbejaan is a woman writing a biography about an author. Reading his novels and unpublished manuscript she finds that the manuscript of her subject anticipates and later even dictates "extra-textual" reality and inserts her into the fiction. The way in which the biography is taken up in the play of intertextuality leads to the perception that the fictional author is an intertextual mirror image of the real author, who belongs to the extra-textual world outside the book. In this way intertextual activity in Die werfbobbejaan destabilizes the frame between fiction and reality. No reading of Die werfbobbejaan can be complete without taking into account the plurality of simultaneously perceived meanings triggered by intertextual activity in the text.
