- Description: Social workers are becoming increasingly involved in community projects, thus allowing them to reach more people. One of these areas involves the sensitising of society in the removal of barriers which prevent people with disabilities from living balanced and integrated lives. One aspect requiring particular attention is the natural environment which, until recently, has been neglected. In order to increase the knowledge of the researcher in the field of environmental accessibility, twenty six people with physical disabilities were interviewed to ascertain which factors they saw as important and relevant when assessing the natural environment. Their ideas were incorporated into practical assessments of a game reserve and a possible hiking trail for people with disabilities. As it is of vital importance to include the consumers in studies of this nature, selected people with varying abilities and disabilities assisted in these "hands on" studies. Qualitative interviews were also conducted on the owners of facilities who were in the process of making their facilities accessible. This allowed the researcher and selected people with disabilities to evaluate positive and negative experiences, thus adding to their knowledge base and building capacity for people with disabilities

- Description: The South African demersal trawl fishery, as with most trawl-directed fisheries worldwide, has a substantial bycatch component. With increasing commercial emphasis being placed on retained bycatch, an urgent need has arisen to investigate these species. In the past the bycatch component has received little research or management attention. Members of the gurnard family Triglidae make up up to 2.4 % of the South African hake-directed demersal catch and are thus considered an important bycatch species. The catch history and biology, including population structure, reproduction, feeding, age, growth and mortality, of the Cape gurnard, Chelidonichthys capensis, sampled from the Agulhas Bank, South Africa, were thus investigated. Males (mean TL = 366mm) were significantly smaller than females (mean TL = 411mm). The sex ratio was close to parity, males being more dominant in commercial trawls and less dominant in research trawls. Gonad maturation and gonadosomatic indices showed this species to have an extended spawning period with peaks in reproductive activity during September, January and April. First approximations of size at 50 % maturity were similar for females (349mm TL) and males (348mm TL) but differed significantly in terms of age (3.6 years and 4.6 years respectively). Otolith growth marks were validated as annuli using marginal zone analysis. The maximum age estimated was 16 years for a female of 675mm TL and recruitment to the commercial fishery was estimated as taking place in the fifth year of growth for both males and females. Gut content analysis showed C. capensis to be an opportunistic feeder preying preferentially on the benthic crustaceans Goneplax angulata and Mursia cristimanus. Landings from the commercial linefishery were insignificant whilst those for the commercial trawl fishery ranged from 500 tonnes to 3250 tonnes between 1984 to 1995, and indicated that this species forms an important component of the South African trawl fishery bycatch. A first approximation of fishing mortality (0.36 year⁻¹) for the inshore commercial trawl fishery was higher than that of natural mortality (0.25 year⁻¹) suggesting some fishing pressure on this species on the Agulhas Bank. However this fishing mortality value was significantly less than that for F₀·₁ (4.78 year⁻¹) that was estimated using a yield-per-recruit model.

- Description: This thesis examines the events that took plac,e. in the Northern Frontier District I North Eastern Province of Kenya hetween the late nineteenth century and 1968. After 1900 the imposition of colonial policies impacted on the socio-economic and political structures of the Somali people. This thesis also examines the nature of Somali resistance l\P- to the late 1920s when Somali society was finally pacified. It further examines colonial policies such as the creation of the Somali-Galla line in 1919, the separation of the J uhaland region from the Kenya Colony in 1926 and the Special District Ordinance of 1934. Between 1946 and 1948 the British Government through its Foreign Minister, Ernest Bevin, attempted to unify Somali territories in the Horn of Africa and this raised Somali hopes of uni fication. The Bevin Plan collapsed because of the opposition of the United States, the Soviet Union, the French and Ethiopian leaders. Similar hopes of NFD Somali unification were raised hetween 1958 and 1963 because of the unification of the former British Somali land and Italian Somaliland. Due to the imminent end of British colonial rule in Kenya, the NFD Somali leaders demanded secession from Kenya to join up with the nascent Somali republic. But the NFDSomali hopes of unification with the Somali Repuhlic were dashed by 1964 because of the same opposition provided by the United States, the French and the Ethiopians. The British Government were all along half-hearted towards Somali unification attempts even though the field administrators adopted a pro-Somali attitude to the issue. In the early 1960s, however, the NFD Somali leaders were faced with the additional opposition of the new KANU government in Kenya. In 1964 the failure of the NFD Somalis to secede from Kenya led to the guerrilla war, what the Kenyan government called the 'shifta movement', that engulfed the North Eastern Region until 1968 when the Arusha Memorandum of Understanding was signed between the Kenyan and the Somali Governments. The signing of the Arusha Memorandum of Understanding by the Kenyan and Somali Governments did not satisfy· the NFD Somalis hopes of joining the Somali Republic. The main conclusion of this thesis is that the N FD Somalis, except for few collahorators, did at no time, whether in the colonial or post-colonial eras, accept heing in Kenya. By the late 1960s the prospects of NFD Somalis unifying with the Somali Republic were, in view of the forces arrayed against the Somali secessionist movement, slim; and they have remained slim since then.

Conservatism and change: the refashioning of gender relations from 1870 to 1914: a case study of East London

- Description: This is a case study of East London from 1870 to 1914 with gender as the critical analytical category. The focus is on change in the structure of gender relations, evaluated in terms of the recognition of the rights of women and their status in society and women of all race groups are dealt with. A feature of the source material has been the use made of oral history where interviews were conducted with the descendants of women who lived during the study period. There were many indirect factors which had a retrogressive influence on progressive change in the rights and position of women. The initial small size of the population and unbalanced gender ratios, the few natural resources, a small and limited port and periodic unpredictable natural disasters gave rise to a 'boom and burst' economy with very little industry. The result was that initially the women were very conservative and unwilling to make social changes. The military occupation and the outbreak of hostilities in the late 1870s affected social and racial attitudes detrimentally. The entrenched patriarchal system, under which both black and white women lived, and the legal controls, particularly in the marital situation, reinforced the subordination of women, making the system difficult to break. Further conservative forces were at work with the European class system being well entrenched, with most women working for upward mobility, gentrification and respectability. Wealth was critical in determining status and those women from the working class, who had achieved some degree of wealth and status, were not prepared to challenge the system. Religion was important for nearly all white women and converted black women, but was a retarding influence in the growth of feminist consciousness. Little progress was made in improving the condition of women who transgressed the law, the non-respectable women, and ethnicity made no difference. Progress was made in gender relations for women in some fields. The reduction in family size and the improvement in health, gave women more time and energy for public affairs. Participation in sport helped women discard the image of being weak and frail and also improved health. Educational opportunities allowed some to get tertiary training and obtain proper qualifications to earn a living for themselves. Xhosa women who came into the town, made a major break with traditional society and many became independent. The major impetus for change came through women's associations, where women actively worked together and achieved some positive results. Middle class white women could earn an independent living without losing respectability, although it was accepted that women should give up paid employment on marriage. Black women broke traditional ties and many urban women became independent. Conditions for working class and non-respectable women changed very little. A deduction is that many women, both white and black, had sympathy for one another and they created a fund of goodwill on both sides of the colour line.

- Description: The study examined rape counselling, with particular emphasis on countertransference reactions experienced by the counsellors of rape survivors. Four subjects participated in semi-focused, open-ended interviews, which were taped and transcribed verbatim. The phenomenon of countertransference was discussed, and countertransference reactions identified and examined. The management of empathic strain, in order to sustain empathic inquiry and therapeutic efficacy, was discussed. The main results of the study included the identification of common victim themes, and the feelings evoked in the counsellor in the therapeutic relationship. These included feelings of anger, hopelessness, helplessness and sadness, particularly in the counselling of children, who may be HIV positive as a result of the attack, and victims of chronic abuse. Challenges of rape counselling included shortcomings in the system, and rape myths which trivialize the crime and blame the victim. The need for education and enlightenment of both the public and magistrates on the deleterious effects of rape was emphasized by all subjects.

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

- Description: 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.

- 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.

Ecological interactions on a rocky shore : the control of macroalgal distribution by intertidal grazers

- Description: The aim of the present study was to determine the potential impact of intertidal grazers on the distribution of macro algae on the south coast of South Africa. Particular attention was paid to the large patellid limpet, Patella oculus, which is found thoughout the intertidal zone. Studies of gut contents revealed that Patella oculus was capable of ingesting not only the thallus of foliose (eg. Ulva spp.) and encrusting coralline macroalgae, but also spores and diatoms. The inclusion of these relatively small particles in the diet was surprising, as electron micrographs of the radula of P.oculus revealed that it is typically docoglossan in structure. Such radulae are thought to be poorly suited for collecting small food particles. Sand made up a significantly higher proportion of the gut contents than other particles at all shore heights, which suggests that P.oculus might be capable of excavating the rocky substratum, or of sweeping up sand, while searching for food. Analysis of the gut contents of other local herbivorous molluscs, was also carried out. These species included the winkles, Oxystele variegata and O.sinensis, and the small pulmonate limpets, Siphonaria concinna, S.capensis, and S.serrata. The guts of all species contained mainly spores and diatoms, although small fragments of Ulva sp. were found. The population structure of Patella oculus was investigated at two sites, Cannon Rocks and Old Woman's River. At Cannon Rocks, mean shell length of low-shore animals was significantly lower than that of both mid- and high-shore animals, while at Old Woman's River, no significant difference was found among shore heights. A regression equation for In (shell length) vs In (dry weight) was calculated, and based on length data, the biomass density (g dry mass.m⁻²) of P.oculus at Old Woman's River was estimated. Values ranged from 2.8 on the low- and midshore to 0.37 on the high-shore. A manipulative field experiment was used to determine the impact of mesograzers and macrograzers (such as Patella oculus) on the distribution of intertidal macro algae on the mid- and low-shore at Old Woman's River. Grazers were excluded using mesh cages (mesh size = 3mm), in two separate experiments, one in winter and the other in spring. Percentage cover of macroalgal species and sessile invertebrates was estimated at approximately 6 week intervals for up to 3 months. MANOV A showed that treatments did not significantly affect cover of macroalgae or barnacles during winter. However, towards the end of the spring experiment (midshore only) cover of barnacles and green foliose turfs did increase in those plots from which mesograzers and/or macro grazers were excluded. The failure of the statistical tests to detect significant differences at some time intervals may have been caused by high levels of variation among replicates. This suggests that factors other than grazing are of overriding importance in determining the distribution of local macroalgae. The existence of a possible symbiotic relationship between Patella oculus and the red foliose alga, Gelidium pristoides, was investigated. The availability of various substratum types, including rock, limpet shells, barnacles etc., and the proportion of the total cover of G.pristoides on each, was calculated. It was shown that a significantly higher proportion of the alga grew on limpet shells, although the availability of this substratum type was low. It is thought that the aggressive behaviour of P.oculus prevents all but juvenile Patella longicosta from grazing on its shell, thus providing a refuge from grazing for G.pristoides.

- 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: 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: Trite as it may sound, the end of the Cold War is a landmark event in the history of human-kind. As such, this thesis was motivated by some of the international and local events that have taken place since the end of the 1980s. At the international level, the end of the Cold War has encouraged the re-examination of the concept of security. In Southern Africa too, this process has been strengthened by the demise of apartheid in South Africa. Initially challenged by a few academics, the traditional conception of security which perceived the threat to 'national' security primarily in the form of external military aggression no longer enjoys the primacy it was accorded during the Cold War era. A 'new' security discourse has emerged, and even though it has not yet made inroads into many governments' policy papers, there is some realisation that people's security concerns go beyond external military aggression to the state. Proponents of this 'new' thinking make reference to people-centred or human security - the notion that people and not the state, must be the objects of security. Arising from that, they point to the existence of many phenomena which should also be accorded security status especially in developing countries where people are confronted by life-threatening challenges such as disease, poverty, famine, and other challenges which do not necessarily threaten life, but if not tackled with urgency could transform themselves into the more conventional military threats. Here reference is made to the proliferation of small arms, political instability, mass migr?tions, and so on. In a region besotted by many of the challenges mentioned above, a security conception informed by the 'new' approach seems more appropriate. The outcome of the traditional approach to security is well known to the region many millions of lives were lost and it is estimated that billions of dollars in revenue were also lost, all in the name of maintaining the security of the South African state. Seeing neighbouring states as threats to its security because they accommodated liberation movements who occasionally instigated military attacks against Pretoria, the former apartheid state through its policy of 'Total Strategy' terrorised the entire region, including the majority of citizens within South Africa. However, since the end of apartheid in 1994, the new democratically elected South African government has committed itself to help build a politically stable, more secure, economically prosperous and integrated region. Through its accession to the Southern African Development Community (SADC), a body which it once tried to undermine, South Africa has further demonstrated a commitment to tackle some of the region's problems in unison with its former adversaries. Throughout the Southern African region there is a realisation that there are more long-term benefits to be gained by working together to tackle the challenges that confront almost all the countries in the region than trying to solve problems independently. Therefore through SADC, primarily a development-oriented body, Southern African states will also seek to address the region's security concerns. Many of the region's governments seem to show an understanding that security and development are intertwined - that they are two sides of the same coin whereby one cannot be attained without the other. Much as this understanding is laudable, in practice it does not seem as if it will translate to the prominence of so-called development issues or marginal security issues. Accepting the 'new' thinking on security also implies an acceptance of a wider range of security agents. It does not mean that by widening the agenda of security to include nonmilitary threats, more tasks will follow for the 'men' in uniform. What it means is that, the military establishment should no longer be the sole agent of security. Instead, where there is no military threat, resources should be channeled to other establishments such as those of health and research in order to fight the spread of AIDS. Furthermore, departments of water, environmental affairs, and so on, should be part of the security policy-making process. In addition, civil society should also be included in the policy-making process. Notwithstanding its limitations, and without undermining inter-governmental projects, civil society can at best promote security by serving as a watch-dog over policies adopted by governments. South Africa during the era of apartheid is a classic example of how governments cannot always be entrusted with the security of ordinary citizens. However, an examination of the structure and terms of reference of the newly created SADC Organ for Politics, Defence and Security (from henceforth referred to as the Organ) reflects a preponderance of the traditional/realist approach to addressing security concerns. It was conceived by, and is primarily constituted by the traditional establishments of security, that is, the military and the police. Some of the Organ's objectives include; security and defence cooperation through conflict prevention, management and resolution and mediation of disputes and conflicts. Nowhere is it evident that others besides those from a military/police background were involved in the formation of this important body. There is also no indication as to how other dimensions of security will be attained through the Organ. All this casts doubt regarding SADC's actual commitment to a development-oriented, people-centred and people-driven security. Nonetheless, current debates on security give hope to the notion that in the future, people's overall security needs will be addressed.

There is also no indication as to how other dimensions of security will be attained through the Organ. All this casts doubt regarding SADC's actual commitment to a development-oriented, people-centred and people-driven security. Nonetheless, current debates on security give hope to the notion that in the future, people's overall security needs will be addressed.

- Description: Students in tertiary educational institutions in South Africa come from many different backgrounds and have varied educational experiences. Some students, especially those from non-English speaking backgrounds, may encounter linguistic difficulties with various academic tasks. In order for students to be successful at university, they must become academically literate. That is, they must master all the reading, writing, listening and comprehension tasks required by the disciplines in which they are studying. One such task is presented by the academic lecture which is an integral part of any course of study. Linguistically, the academic lecture can be seen as a particular genre with unique characteristics. This study investigated some linguistic characteristics of academic lectures. The discipline of Political Science, as a Social Science, was chosen because there is little research that has been done on language in the Social Sciences. The Political Science sub-disciplines of Political Philosophy, South African Politics, and International Relations were used in this research. First year lectures were recorded from each of these three sub-disciplines. The linguistic characteristics of lectures were analysed using techniques drawn from Systemic Functional linguistic theory. The analysis concentrated on the aspects mode and field as they were realised in the lectures. In addition, higher level generic structure was also analysed. The insights gained from the analysis were validated through interviews with the lecturers who gave the lectures. The aim of this research was to develop a linguistic characterisation of the lecture genre as it occurs in the three sub-disciplines of Political Science. The results of this research suggest that although there is a unified academic lecture genre, there is variation according to sub-discipline. The implications of this variation are discussed with reference to their relevance to teaching academic literacy.

Graphicacy as a form of communication in the primary school

- Description: Children of today inhabit a multi-dimensional world, and in order to communicate effectively in it, they need the ability to utilise four forms of communication namely, oracy, literacy, numeracy and graphicacy. Communicating in graphic form requires an ability to both encode and decode spatial information using symbols, which requires the utilisation and application of spatial perceptual skills and concepts. The acquisition of graphic skills has been influenced by traditional developmental perspectives; increasingly the assumptions underpinning these have been challenged by more recent international research findings. The draft Curriculum Framework for General and Further Education and Training (1996: 18) identifies graphic literacy as one of the critical outcomes of the new South African curriculum. For graphic literacy to be an achievable outcome of the new curriculum, we need to investigate the skills and concepts underpinning this form of communication. The goal of this research is to investigate graphicacy as a form of communication in South African primary schools. However, given the scope of a research project of this nature, it was decided that rather than dealing with graphicacy per se, pictures as the most frequent and concrete type of graphic communication encountered by young learners would be focused on. In seeking to investigate pictures, the first stage of the study is concerned with diagnosing and illuminating children's graphic skill development through identifying: what skills they use; how they use and apply these when communicating through and interpreting symbols; and the difficulties they experience when, firstly, encoding spatial information through a series of practical and drawing tasks; and secondly, when reading and interpreting pictures. The second stage of the study investigates the extent to which children's early childhood experiences may or may not have impeded or enhanced the acquisition of skills necessary for understanding and communicating about space. The research findings, evaluated according to existing and emerging theoretical perspectives on graphicacy, will help to illuminate the current situation regarding the graphic literacy of South African primary school children. The study may contribute to wider international debates about graphicacy as a form of communication and the development of graphic literacy, from a South African perspective.

- Description: The medical model has been criticised for its failure to attend to individuals' experience of illness and the meaning they attribute to illness. HIV / AIDS has challenged its adequacy and brought the question of meaning in illness into sharp focus. This study aimed to understand what it means to live with HIV by exploring the fantasies, images and metaphors that make up the depth of such an experience. Phenomenology was deemed the appropriate approach, as it assigns epistemological significance to metaphor and ontological primacy to the lifeworld. An interview guide was fashioned from existing phenomenological literature and in-depth interviews were conducted with eight HIV -infected individuals. Five protocols were selected to constitute the study. In addition, an audio tape recording of one individual's metaphorical dialogue with HIV was obtained and transcribed. The three protocols with the richest content of imagery and metaphor were subjected to phenomenological explication. The remaining two protocols were used to support and clarify emergent meaning. A phenomenological explication of the data revealed a number of salient metaphors and themes. Upon being diagnosed with HIV, individuals were confronted with a socially and institutionally prescribed understanding of the disease; HIV as synonymous with AIDS and immediate death, HIV as sexual deviance, and HIV as myth. These metaphors influenced their conceptualisation and handling of HIV. Individual embodied metaphors included: embodying a heart of stone to live with HIV and perceiving HIV as a punishment from God, a demon from the Devil, a death sentence and a torture. Affectively, the experience of HIV was constituted as fear of physical disfigurement and exposure, anxiety, vulnerability, anger, betrayal, injustice and isolation. In a process of resolution and transformation, individuals imbibed positive metaphors with which to continue living with HIV. In order to cope with HIV, individuals seemed to negotiate a metaphorical space in which to dwell with their virus. This entailed establishing some form of dialogue with HIV or a Higher Power. This study revealed that metaphorical thinking about HIV /AIDS has a powerful impact on individuals' embodiment of their world. Metaphor is also an effective means Clf conveying and eliciting meaning in the experience of illness. Based upon these findings, it was suggested that metaphor be a prime focus for future research endeavours.

- Description: Cysteine plays an important role in many biological and pharmaceutical systems. Therefore, in view of its importance, it is essential to find means of detecting it at the lowest possible levels. In this regard, electrochemical techniques have been found to be capable of detecting analytes even at micro levels. However, electrochemical determination of cysteine occurs at a very high potentials. These overpotentials makes quantitative analysis or detection of cysteine difficult at most conventional carbon electrodes. On platinum electrode, the oxidation of cysteine has been reported to occur in the potential range 0.7 to 1.45 V (vs NHE). Therefore, the object of this investigative study has been to find an active complex that could replace platinum and other expensive metals as electrodes. Such a complex should also be capable of reducing the potential at which the oxidation of cysteine occurs on carbon electrodes. As a result, this manuscript gives a full report on the investigative study of electrocatalytic activity of molybdenum phthalocyanine complexes towards detection of cysteine. Molybdenum phthalocyanine, OMo(OH)Pc, and its tetrasulfonated derivative, [OMo(OH)TSPc]⁴⁻ were successfully used to reduce the potential needed to initiate the oxidation of cysteine on carbon paste electrodes (CPE). The oxidation of cysteine on CPE modified with [OMo(OH)Pc]⁴⁻ was found to occur at 0.29 V (vs Ag/AgCl), and in the presence of [OMo(OH)TSPc]⁴⁻ species in solution the oxidation occurred at 0.33 V (vs Ag/AgCl). Molybdenum, in the oxidation states of Mo(IV), Mo(V) and Mo(VI), is found in biological systems as an essential trace element, participating in a number of enzymatic reactions, where it is believed to be coordinated to sulphur-containing ligands in many molybdenum enzymes. This therefore explains why molybdenum phthalocyanines were employed in electroanalytical detection of sulphur containing amino acid, cysteine. Electrochemical methods have also been successfully used in detection of environmental pollutants such as phenolic compounds. Phenolic compounds are oxidised at readily accessible potentials. However, like cysteine, there are problems associated with the electrochemical detection of these important environmental pollutants. Their electrooxidation is known to form dimeric and/or polymeric oxidation products which adsorb onto the electrode surface, thus -videactivating it. Therefore, to address this problem, cobalt phthalocyanine (CoPc) and its tetrasulfonated derivative, [CoTSPc]⁴⁻ were employed in electrocatalytic detection of phenolic compounds. These complexes were found to increase the anodic peak currents for the oxidation of o-cresol, m-cresol, p-cresol, phenol, 2-chlorophenol and 4-chlorophenol. In addition, CoPc deposited onto the glassy carbon electrode improved the stability of the electrode, by reducing electrode poisoning caused by the electrooxidation products of the mentioned phenolic compounds. The potential at which the oxidation occurred and the current response of individual phenolic compounds depended on the degree of substitution and the type of substituent on the phenol molecule. In general, the current response was found to be lower for chlorinated phenols compared with the cresols and phenol. To establish the role of the central metal in the catalytic process, comparison of the electrocatalytic activity of some of the first row transition metal phthalocyanines, for the detection of mono-substituted phenolic compounds, showed the following trend: Co⁽¹¹⁾ > Mn⁽¹¹⁾ > Fe⁽¹¹⁾Pc > Ni⁽¹¹⁾Pc > Cu⁽¹¹⁾Pc > H₂Pc > Zn⁽¹¹⁾Pc > Bare GCE. A report is also given on electrocatalysis using [CoTSPc]⁴⁻ electrochemically deposited on the glassy carbon electrode. This was also found to enhance the anodic peak currents for the oxidation of all phenolic compounds. A report on the effects of scan rate, operating potential, analyte concentration and other variables is also given.

- 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: This study examines the notion of universal human rights in the context of the importance of social and economic rights for the agency and dignity of human beings. It argues that the recognition of basic rights to what is necessary for physical well-being is essential to any adequate theory of human rights, and that rights of the civil and political variety depend on the recognition of social and economic rights if they are to be exercised. Therefore the secondary status which is usually accorded to social and economic rights results in an imbalanced ideal of human rights both in theory and in practice. This study is an attempt to place second generation rights in their proper context and to argue for them as human rights of equal status and importance. It focuses on the derivation of human rights in general, and shows that second generation rights may be accommodated within this structure. It further supports this position by showing that the categorical differences which are asserted to exist between first and second generation rights are based on a mistaken conception of positive and negative rights and duties, as well as an inadequate conception of liberty. The thesis shows that all rights generate a variety of duties, both positive and negative, and that an adequate theory of rights has to be able to accommodate the inevitability of conflicts of rights at the level of their enforcement. Consequently, this study argues there is no reason to give either class of right primary importance, as both first and second generation human rights are essential to the agency and dignity of a human being, and they are thus interdependent. Furthermore, the thesis shows that human rights can be balanced at the level of the obligations which they generate without compromising the deontological nature of such rights. This thesis argues that a theory of rights which is rooted in the liberal democratic notion of rights, such as that characterised by the choice theory of rights, is inadequate. It therefore argues that a benefit theory of rights must be adopted in order to accommodate conflicts of rights when they arise. The thesis argues that as such conflicts of rights are" most common in cases involving the assertion of social and economic rights, this balancing of rights is of special significance for the enforcement of second generation rights. Furthermore, this thesis argues for a theory of minimal interdependence of first and second generation rights, in order to accommodate the notion of first and second generation rights of equal status and importance, as well as to prevent an inflation of rights claims which would compromise the balancing of rights. It is argued that a reordering of values is necessary to take account of material well-being, as well as civil freedom, as both of these generate fundamental rights of equal status and importance.

- Description: This thesis examines the principles and policies underlying the need for transformation within the Playhouse Dance Company (PDC) in Durban and the actualities of implementing these visions and procedures. It is proposed that artistic structures, ideals and processes cannot remain impervious to the climate of change. Alterations in the political arena demand radical permutations within arts councils and their concept of repertoire, educational programmes and training. Transformation is linked to the problem of identity and it is suggested that the company is in the midst of a journey towards "becoming" rather than "being". Chapter One comprises an overview of changing trends in the arts globally and the impact on South Mrican art forms and processes. There is also an examination of the past, the establishment of arts councils and the colonial heritage of the dance companies within these councils. The formative years of the NAP AC Dance Company and the strategies formulated by former artistic directors have, it is suggested, hampered the transformation process. Chapter Two focuses on the PDC's endeavours to transform between the years 1993 and 1997. Lack of funding, conservative public tastes and training processes are. all' issues confronting management, choreographers, educators and performers in attempting to provide a clear direction towards transformation. The company walk a tightrope as they struggle to balance the heritage of their artistic past while giving birth to a new heritage for the future. Chapter Three discusses two areas that reveal measurable attempts at transformation. Hawkins offers re-inventions of the classics which encourages innovation, and Siwela Sonke was conceived to draw on dance forms located in Kwazulu-Natal in the search for a South Mrican dance aesthetic. Chapter Four investigates whether transformative visions are becoming a reality and suggests how the company could extend the process further. This chapter concludes with .. ideas about the nature of culture and how this informs,the exercise of transformation.

- Description: This thesis examines the principles and policies underlying the need for transformation within the Playhouse Dance Company (PDC) in Durban and the actualities of implementing these visions and procedures. It is proposed that artistic structures, ideals and processes cannot remain impervious to the climate of change. Alterations in the political arena demand radical permutations within arts councils and their concept of repertoire, educational programmes and training. Transformation is linked to the problem of identity and it is suggested that the company is in the midst of a journey towards "becoming" rather than "being".

- Description: Ostriches are an important commercial species in South Africa and are becoming increasingly so in other parts of the world. Fertility and hatchability of artificially incubated ostrich eggs, however, is generally regarded as low compared to other poultry species and to ostriches in the wild. Investigation into specific farming practices at present indicated scope for an overall improvement in productivity through a sound breeding strategy. This thesis investigated factors that affect egg production, fertility, and hatchability of artificially incubated eggs in the Little Karoo region of South Africa. Specific breeding pair combinations accounted for the major variations in egg weight, hatchability, chick production and offspring weight at slaughter age. An appreciable proportion of variation in reproductive traits was attributable to the repeatable nature of breeding pair performance from year to year, even from first breeding attempts, suggesting that selection of good breeding stock can be made from an early age. Artificially incubated eggs showed improved hatchability when eggs were collected two to three hours after lay rather than the following morning. Storing position of eggs did not significantly effect hatchability when eggs were stored for a maximum of one week. The critical zero temperature for ostrich eggs, below which no embryonical development takes place, was found to be ± 25°C and cooling eggs to temperatures below 20°C for complete cessation of embryonic development during storage resulted in better hatchabilities compared to eggs stored at 25°C room temperature. Hatchability decreased when incubator temperatures were raised from 36 to 37.3°C. Large temperature fluctuations and gradients, which encompass detrimental temperatures, persist within forced draught wooden incubators of the type most commonly in use in the Little Karoo region. The highest temperatures occurred at the top of these incubators and will consequently have a negative impact on hatchability. The ontogeny of ostrich egg metabolism showed an exponential increase during the first 70% of incubation followed by a decline to 75% of the peak value between days 31 and 38 of incubation. From peak levels of embryonic development it was calculated that single stage incubators needs an airflow of 54.4 1/egg.hour to maintain oxygen levels just below 21% and carbon dioxide levels below 0.5%. Lower embryonic mortalities were observed when eggs were turned twenty-four times/day in an electronic incubator compared to hand turning twice a day. Eggs rotated through increasing angles between 60 and 90° resulted in a linear improvement in hatchability. In incubators where turning angles were fixed at 60°, lower hatchabilities were overcome by incubating eggs for 2 - 3 weeks in a horizontal position before placing them vertically. No specific farming practice could be singled out as the main cause of low fertility or hatchability but rather a combination of certain practices applied wrongly.

- 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.
