- Description: International politics has always been characterised by conflict. This has been true regardless of the political systems in place or of any specific time in the history of humanity. Inter-state conflict exists today despite the fact that the vast majority of the states of the world are members of the United Nations and signatories to various treaties aimed at removing conflict as a means of state action. The realist school of thought argues that the international system is characterised by continual state conflict, caused by competition over scarce resources. The propensity towards conflict is argued to be an essential characteristic of human nature and, as such, human nature is considered to be aggressive and conflictual. Thus, for the realist, inter-state competition, coupled with aggressive human nature, constitutes the primary cause of interstate conflict. This thesis aims to examine two criticisms of the realist position in depth. The first concerns the attribution of human nature to states. This logical progression is problematic because it creates a type of „state-nature‟ that cannot be defended without providing a logical link between the individual, the group and the state. It is therefore an aim of this thesis to provide this link, using methodological individualism, in order to provide a basis for the attribution of human nature to states. The second aim of this thesis is to examine the notion of human nature that is offered by the realists. It is not enough to claim that human nature is aggressive and conflictual merely because conflict has characterised international relations throughout history. Rather, one should examine the individual‟s psychological development, in order to gain an understanding of aggressive instincts apparent in human nature. The thesis therefore examines psychoanalysis in order to attempt an understanding both of human nature, and of the conditions under which human nature may manifest itself in an aggressive, conflictual manner. The intention of this thesis, then, is to provide a defence of political realism, highlighting the shortcomings of the two criticisms outlined above.

- Description: In the South African (SA) model of community radio, listeners are expected to be in charge of the management and programming operations of stations. This study tests the SA model against the actual conditions at an existing station. For this purpose, the study focuses on Radio Graaff-Reinet, a community radio station in the Eastern Cape. Emphasis is on examining the extent to which members of the station’s target community are involved in its operations. The study first assesses the nature of this involvement, keeping in mind the principles of, ‘community ownership’ and ‘participatory programming’ on which the SA model of community radio is based. It is argued that the station does provide a valuable ‘public sphere’ for its listeners. The potential of this sphere remains limited, however, due to the impact of ongoing power struggles around the ownership of the station. The lack of proper systems for managing these struggles has contributed to the fact that the station continues to be in a constant state of flux, with a high turnover of staff and regular changes in its policies and strategies. The study argues that, until such systems are put in place, the principles of community ownership will not be fully realizable. Areas in which the struggle over ownership plays itself out can be identified in the relationship between the station’s Board of Directors and its managing staff, between one particular station manager and her staff and between the station and its target community. These struggles often take place in context of a debate about the financial sustainability of the station versus its developmental aims. It is argued that this opposition needs to be questioned since, until the station is financially stable, it will remain vulnerable to interference by powerful individuals and groups in its attempts to establish such developmental aims. The study then goes on to identify key weaknesses in the station’s approach to community ownership and participation. In particular, it is pointed out that various stakeholders in the station have contradictory understandings of what is meant by ‘community’, using the term to include or exclude sections of the Graaff-Reinet society in very different ways. There are also very different understandings at play about the concept of community radio itself. These contradictions have an impact on the station’s ability to implement participatory programming. This situation is exacerbated by the fact that the station does not have a consistent forum in which shared decision-making can take place. Consequently, the station also remains unable to draw effectively on its own volunteer staff and on its community as resources for programming content. Finally, the study explores the broader significance of the weaknesses that exist in the case of Graaff-Reinet, arguing that these are problems that repeat themselves throughout the South African community radio sector. Possible strategies for addressing these problems are suggested, including approaches to monitoring and research, training, organizational development and advocacy.

- Description: This thesis expounds the theoretical underpinnings of problem-solving approach to conflict resolution. It also criticizes the traditional state-centric approach to conflict resolution being followed by the Inter Governmental Authority on Development (IGAD) in the Sudanese civil war. IGAD was initially known as Inter Governmental Authority on Drought and Desertification (IGADD), but was renamed IGAD in 1996. Its objectives were reformulated to give priority to conflict prevention, resolution, and management, and humanitarian affairs. It is stipulated in the thesis that IGAD faces problems that need attention if the Sudanese civil war is to be resolved. A key problem is that while IGAD's objectives were reformulated to give priority to conflict resolution, IGAD's management structure has remained the same. The management structure is state-centric and lacks neutrality, which is a very important ingredient in deep-rooted social conflict resolution. The management structure, which was initially based on combating drought and desertification, was not restructured to conform to the realities of a problem solving approach to conflict resolution. The committee that was formed to look into the Sudanese conflict is composed of states in dispute with Sudan. The other structural problem cited in the thesis is that the IGAD peace process is cumbersome and does not include all aggrieved parties. The meetings involve heads of state, ministers, ambassadors and other government representatives. The peace process is not inclusive of other important players such as other rebel movements. This thesis concludes that: 1. there is a need for peace keeping forces from neutral African Union (AU) member states; 2. conflict resolution specialists are deployed in the region whose main task would be to assist the belligerent groups to reach a common understanding of their problems; 3. the United Nations (UN) acts proactively to create international awareness to the Sudanese problem.

- Description: This participatory action research study involved a group of teachers in transforming school grounds into interpretation resources. Approached from a critical perspective, it challenged the conventional top-down approaches to interpretation resources and materials development. Through a teacher-centred approach, a school-based ‘botanic garden’ and ‘arboretum’ were developed at Samaj and Kenya High respectively. Teachers were further actively engaged in developing a variety of interpretive materials that might engage learners in socially critical environmental education processes at the transformed sites. A process in which educators from five non-formal education organisations shared their skills and knowledge on environmental interpretation with teachers preceded the development of interpretation resources and materials. Drawing on Latour (1999), I have applied the notion of mobilising interpretive capital when describing this process. Interpretive capital within the non-formal education sector was mobilised and made available through social interactions between teachers and non-formal educators. This occurred during workshops, organisational visits and critical reviews of a sample of interpretive materials. I provide insights into how the interpretive capital was mobilised and later drawn on by teachers during the development processes in their schools. This study argues that mobilising interpretive capital with teachers through partnerships can enhance the transformation of school grounds to foster environmental learning. It shows how attempts to find solutions with teachers were made in response to pedagogical and curriculum tensions that arise around the implementation of environmental education processes in their schools. To provide orientation in environmental education processes in schools, analyses of socially critical environmental education processes and a review of theoretical perspectives on interpretation as an environmental education process are presented. I have viewed interpretation and environmental education as reciprocally necessary aspects for enabling the development of critical environmental literacy and action competence. To explain this view, the notion of environmental interpretation and education processes has been applied and presented in this study. Finally, practical outcomes of the study on transformation of school grounds, improved education practice, enhanced professional competencies amongst teachers, new interpretive materials in schools and the establishment of partnerships are examined.

Rights to reality - the right to social security, with particular emphasis on the legal resources centre's welfare project in the Eastern Cape

- Description: This research addresses the question of whether the courts have been used effectively to enforce the right to social security in the Eastern Cape. The nature of the right to social security is discussed and placed in the context of constitutional developments in South Africa and South Africa's obligations in terms of international law. The enforcement of socio-economic rights and legislation regarding social assistance is also discussed in detail, along with the problems associated with the social security system such as the gaps in the system, the impact of HIV / AIDS and the problems created by the amalgamation of various administrations. The history of the Legal Resources Centre, a non-governmental organisation which has been involved in public interest law for twenty four years, is detailed. The Grahamstown office's litigation campaign against the Eastern Cape Department of Welfare is then discussed and six landmark cases are analysed in detail. A discussion of the jurisprudential significance and impact of each case on the development of South African administrative and constitutional law follows. A series of stories reported in the press illustrate the human aspect of the campaign and balance the legal argument. These stories may suggest that the Constitution's commitment to social justice and the government's commitment to the principles of Batho Pete are merely noble ideals for many people in the province, but it is argued that the LRC's campaign has made a vast contribution towards making these ideals a reality on the ground. The expert opinions of various groups interviewed during the course of this research regarding the impact of the LRC's litigation campaign are discussed, and the conclusion is drawn that it has indeed had a positive effect. They include paralegals at Advice Offices around the province, legal practitioners from the LRC, a private legal practitioner, several representatives of the Black Sash, a former MEC for Health and Welfare in the Eastern Cape Provincial Government, an official from the Department, and a leader of the Anglican Church in the province. In conclusion it is submitted that, but for the LRC's litigation campaign, the situation in the Eastern Cape would not have improved to the extent it has and may even have deteriorated further. Furthermore, it is submitted that as a result of the litigation campaign, the right to social security, and particularly the right to social assistance, is more accessible and more of a reality on the ground.

- Description: This thesis examines small-scale rural fisheries which were initiated in two villages by the Department of Ichthyology and Fisheries in conjunction with the Institute of Social and Economic Research in 1997. The main objective for undertaking the study was to determine the potential of the fisheries to serve as viable and sustainable options that could contribute towards rural development in the area of study. To examine the contribution made by the small-scale fisheries towards rural development in the villages, it is imperative to have an understanding of the context in which they were established as well as the prospects for sustainable development. It is argued in this study that despite the significant contribution made by inland rural fisheries in improving rural livelihoods they are still accorded minimal support and attention in South Africa. As an illustration of the important role played by rural fisheries, case studies from Malawi and Zimbabwe have been drawn into the study with a view to providing lessons for rural areas of South Africa. The study took place at a time when natural resources in the villages were significantly declining and environmental degradation reaching uncontrollable proportions, so there is an urgent need to secure an alternative mode of subsistence for the population in the villages. Development interventions by the state and non-governmental organisations in the study area have not been sustainable and they collapsed within a short period of time. A case in point is the Tyefu irrigation scheme, which was initiated in the villages but, owing to various factors, it failed leaving the villagers with a diminished mode of subsistence, thus providing the impetus for the implementation of small-scale rural fisheries. In order for small-scale fisheries to be sustainable it is essential to adopt models that are aimed at sound natural resource use and management. This study has raised various issues pertinent to natural resource use and management in the study area. A model for management of natural resources that involves and aims to empower local communities in the management of the fisheries is presented in the study. It has also been demonstrated that rural fisheries in the study area comply with the model. Finally, the study draws the conclusion that small-scale fisheries in the villages contribute towards rural development, however, there are constraints that need to be eradicated.

- Description: This study attempts to make a contribution to the debate on the role of South Africa within Southern African Development Community. An attempt is made to analyse this role within the context of regional integration debate. This role has been conceptualised within the dichotomies of hegemon versus partner. The study argues that South Africa is a hegemon in the region of SADC, and that given its overarching economic dominance and it has the potential of establishing its hegemony in the region. It maintains that there are several factors, which could facilitate South Africa's hegemonic dominance such as in military, technology and manufacturing sector. It concludes by arguing that given the changing geopolitical factors both within the region and the globe impedes South Africa from firmly expressing this hegemonic dominance. Furthermore, South Africa's pioneering role in the struggle to change the status quo globally in favour of the Southern states is another crucial factor, which imposes limitations on its hegemonic intentions regionally.

- Description: Forensic entomology is an emergjng field in South Africa. Little is known about South African blowflies and factors that affect their use in a forensic context. This work provides a review and synthesis of previous work in South Africa and supplements some of the background and basic knowledge required for forensic entomology in South Africa. The seasonal occurrence of eight forensicaIIy important blowfly species was quantified by fortnightly trapping in Grahamstown, South Africa. The spatial distribution of each species was related to seasonal occurrence and habitat preference. Seasonal distributions of blowflies in carcasses in South Africa were obtained from the literature and compared to the seasonal trapping. By mapping South African locality records of forensicaIIy important blowflies and analyzing these records in a modified Principal Components Analysis of climatic data, the potential geographic distributions of each fly species was modeIIed. Most species were widespread, but Calliphora croceipalpis, Jaennicke, 1867, was found in cold places. This information is important for determining where certain species are likely to occur in forensic investigations. Nocturnal oviposition was examined in both field and laboratory experiments. Lucilia species could oviposit nocturnaIIy in the field, while Lucilia species, Chrysomya chloropyga, (Weidemann, 1818) and C. putoria (Weidemann, 1830) could oviposit nocturnaIIy in the laboratory. These findings are important factors in affecting the precision of estimates of a post mortem interval (PM!) by up to 12 hours. The thermophysiological ranges of four species of adult blowflies were determined by measuring onset temperatures of four significant behaviours: onset of neural activity; onset of coordinated movement; shade-seeking and death. There was a sexual size dimorphism in Lucilia species, Chrysomya chloropyga and Calliphora croceipalpis with females being larger than males. Chrysomya megacephala (Fabricius, 1794) had an unexpectedly high death threshold, while Calliphora croceipalpis had the lowest death threshold of the flies tested. These points were related to the seasonal and geographic occurrence of each species, to nocturnal activity and placed in a forensic context.

- Description: In contrast with the large number of poorly performing schools in Swaziland over the past decade (1991-2000), a few schools have managed to attain consistently good results. One such school is St Michael's High. This study draws on the perceptions of different major stakeholders at St Michael's of factors deemed to have contributed to academic success at the school. The study thus follows Fertig (2000), who advocates research in effective schools to be done by looking at the perceptions of different stakeholders rather than in relation to an objective checklist. In this study, St Michael's High is found to be an effective school. Its experience can play a vital role in helping other ineffective and failing schools to improve their academic standing and tarnished public image, provided the schools unreservedly commit themselves to changing their ways. This investigation is aimed at understanding the roles which the school leadership and associated stakeholders have played in making St Michael's an exemplary school in Swaziland. Its findings indicate that the schools that themselves take the initiative to improve their effectiveness are the ones which are successful, which accords with the consensus in research literature on school effectiveness. The evidence gathered in this study suggests that St Michael's is characteristic of such effective schools. Since this is a qualitative interpretive case study on perception of success factors in a girls' high school within the city of Manzini, interviews comprising semi-structured questions were highly useful in tapping the understanding of how various stakeholders contribute to the academic achievement of students in the school. The findings, organised in the form of themes, help illuminate what appears to be a systematic and well-focussed approach toward the academic development of the school and the fulfilment of its goals. Every aspect of the school system is thoroughly explored. The validity of the stakeholders' claim that St Michael's High is a dream school for most Swazi children is verified by the school's examination results for the past decade. But what the research reveals are the cultural, academic, social, and moral values and beliefs which serve as a strong anchor for the school leadership and management, and without which St Michael's as an organisation would be unable to meet the challenge of implementing academic and national reconstruction.

- Description: This mini-thesis is located in historical discursive practices, choreographing history, biography as a source for making dance in South Africa and choreographic transformations in South African choreography since the 1994 democratic elections. Derridian concepts of deconstruction will be referenced in an attempt to focus the argument of this research, which comments on choreographic transformations since 1994, by subverting the influence of the 'violent hierarchies' enforced by the apartheid regime on South African cultural life and choreographic identity. The researcher draws on these considerations in order to explore the hybrid nature of South African choreography that has emerged since 1994. Chapter one examines the fallacious nature of historical discourse through a consideration and application of Derrida's notions of deconstruction and fabrication. Chapter two explores the notion of choreographing history in theatre through a focus on the objective/subjective fallacy and the history of the body as a textual medium. Chapter three focuses the study specifically in biography as a discourse within the idea of theatre. This approach to biography can be encapsulated by the phrase 'telling lives'. This chapter also explores the relationship between the traditional binaries of writing as a purely cerebral act and choreography as a purely visceral experience. Chapter four brings the focus to the specific post-apartheid South African context. This chapter considers the hybrid forms of dance emerging in South Africa as well as the notion of protest in relation to theatre and dance. The final chapter is an investigation and analysis of two choreographic works created by South African choreographers since 1994 in relation to biography and concepts of deconstruction. These works are Gary Gordon's Bessie's Head (2000) and Gregory Maqoma's Miss Thandi (2002). The focus of the analysis also reveals the inherent difficulty in objective interpretation, and considers the problematics of collaboration and autobiography when choreographing within a biographical context.

- Description: During the 1990’s many South African companies experienced the need to change and adapt. This was largely because of the environmental changes brought about by a new political regime. One of these changes was the exposure of South African companies to global competition. Because the South African business environment had remained relatively static during the 1980’s, many companies had no idea of how to manage change when it became necessary for economic survival. This inability led to the demise of many organisations. As change as a business concept covers a vast area, the main objective of this study was to isolate one area of change and examine it in a practical context. The chosen area was the relationship, if any, between strategy and organisational structure. The practical context chosen was an organisation, which had recently undergone strategic change. The research methodology for this study included the conducting of an intensive literature study, to determine the academic stance on the strategy/structure relationship. Various academic theories were examined to determine whether there was a relationship between the two concepts, and if so, what the relationship should be. This provided a background for the practical evaluation. Literary opinion showed consensus that there was indeed a relationship between the two; in fact the one was integral to the success of the other. That is, if an organisation chooses to consider adopting a change strategy, it should carefully consider its impact on organisational structure. To summarise, in a situation of change, structure should support strategy to ensure a successful transition. An empirical study was then conducted at Pennypinchers (Pty) Ltd , which had recently undertaken to implement a change strategy.

- Description: Zea mays plants kept at ambient (ca 375ppm) and elevated CO₂ (ca 650 to 700ppm) were used to examine the possibility of a symplasmic loading, unloading and transport pathway in dark-adapted and illuminated (200μmolm⁻²sec⁻¹ ) sink and source leaves. 5,6-carboxyfluorescein diacetate was introduced into the mesophyll cells and symplasmic transfer observed 3h after application. In sink and source leaves exposed to ambient CO₂ and illuminated at 200 molm-2sec-1, the fluorescence front was observed approximately 3cm from the point of application, while in dark-adapted plants, the fluorescence front was observed approximately 1cm from the point of application. Under elevated CO₂ conditions the fluorescence front in illuminated plants appeared to transport faster moving approximately 5cm from the point of application, and in dark-adapted plants, only 3cm from the point of application. Based on the increase in 5,6-CF accumulation under elevated CO₂ conditions, the present study suggests that there was an increase in capacity for assimilate loading and transport under elevated CO₂ conditions. In source leaves, 5,6-CFDA was taken up into the mesophyll cells, loaded symplasmically and transported basipetally. In sink leaves 5,6- CFDA was taken up from basal mesophyll and after symplasmic loading, was transported acropetally where it was offloaded into the younger immature sink region. Transport in the sieve tubes was confirmed by using aniline blue, which was applied 3h after 5,6-CF transport. Aniline blue coupled with 5,6-CF transport studies showed that the sieve tubes of both cross and longitudinal veins are involved in symplasmic unloading, loading and transport processes in sink and source leaves. Apoplasmic uptake of 5,6-CFDA by cut leaves showed that after apoplasmic transport via the transpiration stream, 5,6-CFDA was offioaded to the xylem parenchyma where it was metabolically cleaved , releasing fluorescent 5,6-CF into the xylem parenchyma. Transverse sections cut after 3h of uptake were observed after 120 and 180 min suggesting that a retrieval of solutes occurs from the xylem to the xylem parenchyma, bundle sheath, phloem parenchyma and to the th in-walled sieve tubes. It was not possible to determine if the thick-walled sieve tubes were involved or if they took up 5,6-CF. Given the available data on loading and offioading of assimilates in sink and source leaves respectively, this study demonstrated that a slow symplasmic pathway exists from the mesophyll to the phloem, and that offloading from the phloem in sink leaves can occur via a symplasmic route.

- Description: The synthesis of symmetrically and unsymmetrically substituted zinc phthalocyanines (ZnPc) derivatives is done according to reported procedures. The unsymmetrical ZnPc derivatives are synthesized by ring expansion of sub-phthalocyanine complexes. Ring substitution is effected with tert-butyl phenol, naphthol, and hydroxybenzoic acid. Comparison of the redox potentials for the complexes substituted with varying numbers of tert-butyl phenol: 1, 2, 3, 6 and 8 show that the complex with the highest number of substituents are more difficult to oxidize and easier to reduce. Water soluble sulphonated ZnPc (ZnPcSn) was prepared. The possibility of using axial ligation to increase the solubility and the photochemical activity of sulphotnated ZnPc in aqueous solutions was investigated. Pyridine, aminopyridyl and bipyridyl were used as axial ligands. When bipyridyl was used as the axial ligand, solubility of the ZnPcSn increased, shown by the increase in the Q-band of the monomer species in solution and the singlet oxygen quantum yields was relatively higher than that of the unligated ZnPcSn. The singlet oxygen quantum yields by the various complexes in DMF using diphenylisobenzofuran as a chemical quencher for organic solvent were determined. Singlet oxygen quantum yields for the unsymmetrically ring substituted complexes range from 0.22 to 0.68. Photobleaching quantum yields are in the order of 10-5, which means that the complexes are relatively photostable.

- Description: Successful organisations have a well-defined mission and a strategy for accomplishing that mission. The organisation strategy involves the building of a competitive advantage in a defined market. Activities are oriented around this business strategy. When utilised effectively, technology is a powerful instrument for enhancing the organisation’s competitiveness. Technology management is the application of managerial techniques most suitable for ensuring that the technological factor is exploited for achievement of an organisation's goals. It is critical to correctly implement appropriate practices related to technology and innovation management at organisational level. Most organisations are technology intensive and deliver products or services. The research investigates, through the use of technology auditing, the present and future technology needs of the organisation. It also tried to establish the impact of technology auditing on the competitive advantage of the organisation. The research attempts to set a strategic context for the array of tools, technologies and standards emerging to support the organisation. The research analysed the potential of technology auditing to facilitate a dynamic scale of economy where the organisations take on the tasks of managing its technology. Basic theoretical principles of a technological audit were applied when the researcher conducted the technology audit. Because there is no organisation that is an exact replica of another, a technology audit must be custom made for the specific organisation where it is conducted. A micro business, MP Engineering, in the Port Elizabeth Metropole was chosen to conduct the technology audit at for the purpose of this research project. The research results confirmed the literature currently available.

- Description: Successful organisations have a well-defined mission and a strategy for accomplishing that mission. The organisation strategy involves the building of a competitive advantage in a defined market. Activities are oriented around this business strategy. When utilised effectively, technology is a powerful instrument for enhancing the organisation’s competitiveness. Technology management is the application of managerial techniques most suitable for ensuring that the technological factor is exploited for achievement of an organisation's goals. It is critical to correctly implement appropriate practices related to technology and innovation management at organisational level. Most organisations are technology intensive and deliver products or services. The research investigates, through the use of technology auditing, the present and future technology needs of the organisation. It also tried to establish the impact of technology auditing on the competitive advantage of the organisation. The research attempts to set a strategic context for the array of tools, technologies and standards emerging to support the organisation. The research analysed the potential of technology auditing to facilitate a dynamic scale of economy where the organisations take on the tasks of managing its technology. Basic theoretical principles of a technological audit were applied when the researcher conducted the technology audit. Because there is no organisation that is an exact replica of another, a technology audit must be custom made for the specific organisation where it is conducted.

- Description: This study is a case-study of a patient who was diagnosed as having co-morbid Anorexia Nervosa and Factitious Disorder. It would appear that central to an understanding of both of these disorders is the patient's disturbed relationship to her own body. The existing literature on co-morbid Factitious Disorder and Anorexia Nervosa is rare, with only three cases published. A careful reading of these cases suggests that in all of these cases, Factitious Disorder may have been the primary diagnosis. In this case there was as overidentification with the patient role, and the patient's anorexic symptoms appeared to serve the function of meeting the patient's acute dependency needs. Thus, the patient's Anorexia Nervosa masked the Factitious Disorder and appeared to be secondary to the Factitious Disorder. It is argued that these disorders share several common dynamics, namely the inability to separate from the mother, high parental expectations as well as the use of the body as a transitional or pre-cursor object. In addition there are some common dynamics in the psychotherapy of these patients. All of these factors suggest that in both these disorders the developmental arrest may be located at a pre-verbal level.

- Description: To know your law and not to understand it is like a legal barbarian lost in the battlefield of legal theory. A proper and thorough understanding of the law of evidence and hearsay evidence in particular, is of paramount importance not only for lawyers but also for persons who regard themselves as labour law experts. It takes a great deal of experience before a lawyer truly becomes confident with the law of evidence and its application. The only way one becomes good at it is firstly to know the law. (Where does it come from and why is it there?) Then one must get to understand it by looking at examples and apply it in practice. Only then will a person gain practical experience. The aim of this treatise is not to try and educate experienced lawyers. This article is aimed at those that need some motivation to pursue their journey in the labour law process. Remember we all assume that lawyers know and understand their subject until they proof the contrary. In this work I shall try to highlight the importance of the law of evidence in labour law proceedings. Firstly the meaning of the law of evidence and hearsay evidence is considered. Further emphasis will be on the approach and application of the law of evidence, and in particular the hearsay rule, in labour law proceedings.

- Description: The enzymatic reduction of a high-valence form of metals to a low-valence reduced form has been proposed as a strategy to treat water contaminated with a range of metals and radionuclides. Metal reduction by sulphate reducing bacteria (SRB) is carried out either chemically (involving reduction by hydrogen sulphide) or enzymatically (involving redox enzymes such as the hydrogenases). While reduction of metal ions by hydrogen sulphide is well known, the enzymatic mechanism for metal reduction is poorly understood. The aims of this study were to investigate the role of SRB in facilitating platinum removal, and to investigate the role of a hydrogenase in platinum reduction in vitro. In order to avoid precipitation of platinum as platinum sulphide, a resting (non-growing) mixed SRB culture was used. The maximum initial concentration of platinum (IV), which SRB can effectively remove from solution was shown to be 50 mg.l⁻¹. Electron donor studies showed high platinum (IV) uptake in the presence of hydrogen, suggesting that platinum (IV) uptake from solution by SRB requires careful optimization with respect to the correct electron donor. Transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) analysis indicated that platinum was being precipitated in the periplasm, a major area of hydrogenase activity in SRB. Purification of the hydrogenase by ammonium sulphate precipitation (65%), Toyopearl-Super Q 650S ion exchange and Sephacry 1 S-100 size exclusion chromatography revealed that the hydrogenase was monomeric with a molecular weight of 58 KDa, when analyzed by 12% SDS-PAGE. The purified hydrogenase showed optimal temperature and pH at 35°C and 7.5 respectively, and a poor thermal stability. In vitro investigation of platinum reduction by purified hydrogenase from mixed SRB culture showed that hydrogenase reduces platinum only in the presence of hydrogen. Major platinum (IV) reduction was observed when hydrogenase was incubated with cytochrome C₃ (physiological electron carrier in vivo) under hydrogen. The same observations were also noted with industrial effluent. Collectively these findings suggest that in vitro platinum reduction is mediated by hydrogenase with a concerted action of cytochrome C₃ required to shuttle the electron from hydrogenase.

- Description: The pandemic of HIV/AIDS has challenged several aspects of contemporary social life. HIV/AIDS counselling has developed as a social response to provide support for those infected with the disease. Due to the nature and complexity of the disease, HIV/AIDS counsellors encounter a diversity and intensity of emotions when counselling. A support system that includes effective management and supervision may assist in resolving emotions and reactions that HIV/AIDS counsellors may experience as a result of working with HIV/AIDS clients. This study examines the difficulties that both managers and the HIV/AIDS counsellors at a rural district hospital in the Eastern Cape and its surrounding clinics are faced with, in providing the HIV/AIDS counsellors with the support they need. Engestrom's (1987) model of activity theory was used as a conceptual framework guiding both the analysis and interpretation of the data. This model facilitates the identification of tensions and contradictions thereby opening a space for change and transformation within an activity system. Multiple sources of data collection were used that included focus groups with managers and HIV/AIDS counsellors, interviews with senior hospital staff and an official from the Department of Health, Eastern Cape, and a tour of the rural district hospital. The findings suggest that HIV/AIDS counsellors do not feel supported by their managers. Managers in turn are of the opinion that they do not offer the support the HIV/AIDS counsellors' need. The lack of support is attributed to geographic distances between hospitals and the clinics they serve, lack of available transport and the multiplicity of roles of both managers and the HIV/AIDS counsellors.

- Description: The aim of this study was to compare the quality of oral interaction between a grade 5class and their teacher when either English or isiXhosa was used as medium ofinstruction in two different lessons and of their writing which arose out of the lessons. The research was carried out within the interpretive paradigm and took the form of a casestudy. The researcher took the stance of being a non-participant observer. A variety oftechniques were used to collect data, namely, piloting, video recording and transcribing lessons, observing and making field notes, questionnaires and an interview. The interview was recorded and transcribed by the researcher. The two lessons were transcribed and analysed. Also the learners’ writing was analysed. The findings of this study showed that learners have little competence in English compared to isiXhosa. As a result most of them used short and vague sentences when responding to and discussing pictures in English. They also used short and simple sentences when writing in English compared toisiXhosa. Although this is a small-scale study it is recommended that the school’s language policy is revised and teachers are equipped with necessary skills, which would help them teach English to second language learners effectively. It is also recommended that the learners’ first language continue to be well taught even if it is no longer the classroom language.

- Description: The right to legal representation at labour proceedings of an administrative or quasi-judicial nature is not clear in our law, and has been the subject of contradictory debate in the South African courts since the1920’s. Despite the ambiguities and uncertainty in the South African common law, the statutory regulation of legal representation was not comprehensively captured in labour legislation resulting in even more debate, especially as to the right to be represented by a person of choice at these proceedings in terms of the relevant entrenched protections contained in the Bill of Rights. The Labour Relations Act 12 of 2002 (prior to amendment) is silent on the right to representation at in-house disciplinary proceedings. Section 135(4) of Act 12 of 2002 allows for a party at conciliation proceedings to appear in person or to be represented by a director or co employee or a member or office bearer or official of that party’s registered trade union. Section 138(4) of the same Act allows for legal representation at arbitration proceedings, but subject to section 140(1) which excludes legal representation involving dismissals for reasons related to conduct or capacity, unless all parties and the commissioner consent, or if the commissioner allows it per guided discretion to achieve or promote reasonableness and fairness. The abovementioned three sections were however repealed by the amendments of the Labour Relations Act 12 of 2002. Despite the repealing provision, Item 27 of Schedule 7 of the Amendment reads that the repealed provisions should remain in force pending promulgation of specific rules in terms of section 115(2A)(m) by the CCMA. These rules have not been promulgated to date. The common law’s view on legal representation as a compulsory consideration in terms of section 39 of the Constitution 108 of 1996 and further a guidance to the entitlement to legal representation where legislation is silent. The common law seems to be clear that there is no general right to legal representation at administrative and quasi judicial proceedings. If the contractual relationship is silent on representation it may be permitted if exceptional circumstances exist, vouching such inclusion. Such circumstances may include the complex nature of the issues in dispute and the seriousness of the imposable penalty ( for example dismissal or criminal sanction). Some authority ruled that the principles of natural justice supercede a contractual condition to the contrary which may exist between employer and employee. The courts did however emphasize the importance and weight of the contractual relationship between the parties in governing the extent of representation at these proceedings. Since 1994 the entrenched Bill of Rights added another dimension to the interpretation of rights as the supreme law of the country. On the topic of legal representation and within the ambit of the limitation clause, three constitutionally entrenched rights had to be considered. The first is the right to a fair trial, including the right to be represented by a practitioner of your choice. Authority reached consensus that this right, contained in section 35 of the Constitution Act 108 of 1996 is restricted to accused persons charged in a criminal trial. The second protection is the entitlement to administrative procedure which is justifiable and fair (This extent of this right is governed y the provisions of the Promotion of Access to Administrative Justice Act 3 of 2000) and thirdly the right to equality before the law and equal protection by the law. In conclusion, the Constitution Act 108 of 1996 upholds the law of general application, if free and justifiable. Within this context, the Labour Relations Act 66 of 1995 allows for specific representation at selected fora, and the common law governs legal representation post 1994 within the framework of the Constitution. The ultimate test in considering the entitlement to legal representation at administrative and quasi judicial proceedings will be in balancing the protection of the principle that these tribunals are masters of their own procedure, and that they may unilaterally dictate the inclusion or exclusion of representation at these proceedings and the extent of same, as well as the view of over judicialation of process by the technical and delaying tactics of legal practitioners, against the wide protections of natural justice and entrenched constitutional protections.
