- Description: A mulch tower (MT) system for greywater treatment is introduced in this paper. Materials used to assemble the MT system included mulch, coarse sand, fine and coarse gravel. Limited removal efficiency of the MT system was demonstrated for alkalinity, total hardness, pH, Cl–, PO43–, NH4+, and SO42–, with the estimated cumulative removals ranging from 7 to 12%. Intermediate removal efficiency was observed for chemical oxygen demand (COD), NO3–, and S2– with the estimated cumulative removals ranging from 24 to 28%. The highest removal efficiency was observed for the total suspended solids (TSS) with the estimated cumulative removal equal to 52%. Given the minute residence time in the MT system, the results obtained were promising and justify scale-up studies for potential on-site applications. The MT effluent did not meet hygienic norms with respect to the faecal coliform concentration (FC) and the total coliform concentration (TC), and further effluent treatment is required before any discharge or reuse of the treated greywater. Further research should focus on characterisation of the microbial community of the MT, and the fate of Cl–, PO43–, NH4+, and SO42–.

- Description: Manganese acetate octakis-(2-diethyaminoethanethiol) phthalocyanine (AcMnODEAETPc) was newly synthesized and characterized by spectroscopic and electrochemical methods. Solution electrochemistry of the complex showed three redox processes assigned to MnIIIPc−1/MnIIIPc−2, MnIIIPc−2/MnIIPc−2 and MnIIPc−2/MnIIPc−3 species. The new molecule was polymerized onto a glassy carbon electrode (GCE) to form thin films of different thickness, giving poly-10-AcMnODEAETPc-GCE, poly-20-AcMnODEAETPc-GCE and poly-30-AcMnODEAETPc-GCE, where 10, 20 and 30 represent the number of voltammetry scans during polymerization. Three distinct redox processes were observed on the modified electrode in 0.1 M phosphate buffer solution, pH 5, which confirmed the formation of the polymer. The current signal due to the herbicide, bentazon, was dependent on film thickness; the best signal was obtained on poly-20-AcMnODEAETPc-GCE while poly-10-AcMnODEAETPc-GCE gave the least signal. However, the signals due to the herbicide were better on the different films compared to the bare electrode. Electrochemical impedance spectroscopy (EIS) technique revealed that differences in film thickness offered different charge transfer resistances, Rct, hence difference in current signals for bentazon oxidation were observed on these films. A Tafel slope of 77 mV/decade, obtained for the herbicide on poly-20-AcMnODEAETPc-GCE, denotes a fast one electron transfer followed by a slow chemical step in the electro-oxidation of bentazon. The voltammetry signals of the herbicide on the films indicated the likely involvement of ring-based redox processes in the detection of the herbicide. A plot of background corrected current response, on this film, versus the concentration of bentazon was linear within the range 50–750 μM with a detection limit of 2.48 × 10−7 M.

- Description: Racism has informed South African society since colonial times. Racist beliefs found expression in the laws of colonial and apartheid South Africa and shaped both state and society. The constitutional state that South Africa has become since 1994, is based on the values of ‘human dignity’, ‘the achievement of equality’ and ‘nonracialism’, among others. Law formed the basis of the racist state prior to 1994, and now law has a fundamental role to play in the transformation of the state and society in an egalitarian direction by addressing socio-economic inequalities on the one hand, and by changing patterns of behaviour based on racist beliefs forged in the past, on the other. This thesis examines one of the legal instruments that is intended to contribute to transformation in the latter sense, namely the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 (the Equality Act), with specific reference to the issue of racism. The provisions of this Act and the framework for its operation against the background of South Africa’s racist past, and within the broader framework of international and constitutional law, are examined. These two legal frameworks are analysed for the purpose of determining the standards set by international and constitutional law regarding racial equality in order to determine whether the Equality Act measures up. This thesis also incorporates an analysis of the practical application of the provisions of the Equality Act to complaints of racism in selected equality courts. The theoretical analysis of the Act’s provisions and their application in the equality courts point to various problematic formulations and obstacles which negatively affect the application of the provisions and thus hamper social change. The thesis concludes with recommendations for refining the Act’s provisions and its application.

- Description: This psychobiographical study of Helen Keller’s life is exploratory-descriptive in nature. The subject was chosen through purposive sampling. The choice was based on the researcher’s personal interest and the remarkable impact this profoundly handicapped woman had within her society. Helen Keller also meets the psychobiographical requirements. These include that she is historically well known, inspirational, and her life has been completed. The study uses a qualitative, single case, interpretive research design. The design is employed to study Helen Keller’s entire life span within a formal psychological theory. The theory used in this study is Daniel Levinson’s (1996) Life Structure theory of adult development. Data for this study were collected from a variety of primary and secondary sources which provided alternative perspectives on her life. In addition, the data have been corroborated by historical texts, and newspaper and journal articles. Levinson’s (1996) theory divides the lifespan into four developmental eras, each with its own biopsychosocial character. Each era in turn is divided into shorter periods of development, each with particular developmental tasks. Cross-era transitions separate the eras. By describing and exploring the data according to this theory, Helen Keller as a profoundly handicapped person is shown to display universal patterns of development as suggested by Levinson. At the same time, the Life Structure she developed, her life components, and Satisfactoriness illuminated her uniqueness. Through the application of the theory to Helen Keller’s life, this psychobiographical study facilitated an examination of the theory. This led to suggestions for potential development of the theory.

- Description: Lifestyle diseases such as obesity have been neglected in developing countries partly due to a more urgent focus on infectious diseases in these countries. The incidence of obesity is on the increase in developing countries, with a marked rise in childhood obesity. A health promotioning service-learning principles required final year pharmacy students to prepare a pilot-tested computer-based quiz, using a pre- and post-intervention test design, along with other learning material, for participants at the 2007 Sasol National Festival of Science and Technology (SciFest). Interactive models, posters and information leaflets were used in explaining the prevention and control of obesity to learners. The results showed that the pre-existing knowledge of the participants was good. There was a further improvement after the educational intervention. Activities such as this are important in heightening awareness of obesity in learners as it is likely to reduce the incidence of obesity later in life. Furthermore, the activity also served to increase awareness of the role of pharmacists in the prevention of lifestyle diseases such as obesity.

- Description: Risk is the result of two interacting components: hazard and vulnerability. Climatic hazards are related to extrinsic factors such as drought or severe storms. Vul- nerability is the result of intrinsic factors that often arise from the socio-political- economic context. The interplay of risk and vulnerability is difficult to predict. Although computer models have been widely used to forecast climate related risk, albeit with con- siderable uncertainty, they can never capture sufficiently the vulnerability of human sys- tems to these hazards. Role-playing games can be used more realistically to simulate pos- sible outcomes of different climate change scenarios, and allow players to reflect on their significance. The authors have developed the African Catchment Game to simulate a wa- ter scarce African country. Risk can be modelled mechanistically by changing the nature of the annual rainfall input. Vulnerability can in part be modelled by changing the start- ing parameters (such as access to land and resources) and, secondly, through the unpredictable response of players to game dynamics. Players’ reflections demonstrate that through the game they become more aware of the concept of risk and the complex response of individuals and societies that determine their vulnerability to climatic hazards. This paper reflects on the potential for developing the game further as a tool for participatory learning around climate change, based on the authors’ experience of playing the game with participants from South Africa.

- Description: Addiction is a complex social phenomenon resulting from psychological and physiological dependence. The aim of the study was to create a clinical impression of the lived experiences of cocaine dependents. A transcendental phenomenological approach was used to elicit the essence of addiction as experienced by the participants. Theoretical sampling ensured relevant participants were selected through haphazard sampling procedures. Data was collected through the use of biographical questionnaires and individual, semi-structured interviews with three cocaine dependents. Data was processed according to the four phenomenological principles epoche, phenomenological reduction, imaginative variation and synthesis using Tesch’s eight steps. The essence of cocaine dependency is contained in the psychological experiences of the drug which define and perpetuate that addiction. The psychological addiction develops prior to physical dependence resulting in an entrenched addiction before treatment is sought by the cocaine dependents.

- Description: This thesis centres on the debates informing the progress of three public art galleries in South Africa between 1990 and 1994. This was a period of great change in the country, spanning from the unbanning of left-wing political parties and Nelson Mandela’s release from prison, to the first democratic elections which resulted in his inauguration as President of South Africa. The study focuses specifically on the Johannesburg Art Gallery, the South African National Gallery, and the Durban Art Gallery, delineating the events and exhibitions held, the programmes initiated, and the artists represented by these galleries during this post-apartheid/pre-democracy phase of the country’s history. The debates relevant to these galleries linked to those prevalent in the arts, museology, and politics at the time. Many contemporary South African artists called attention to apartheid oppression and human rights abuses during the 1980s. After 1990, with these pressures alleviating, there was a stage of uncertainty as to the role, responsibility, and focus of visual art in a post-‘struggle’ context, however there was also an unprecedented upswing in interest and investment in it. On a practical level, the administration of the arts was being re-evaluated and contested by both independent and politically-aligned arts groups. Public art museums and sponsored art competitions and exhibitions made increasing efforts to be ‘representative’ of South Africans of all races, cultures, creeds, sexes and genders. The many conferences, committees, and conventions created during this transitional era focused on the creation of policies that would assist in nation-building; historical and cultural redress and regeneration; and the education and representation of previously disadvantaged groups. This coincided with a revolution in museological discourses internationally, from the theorization of a museum as a place of commemoration and conservation, to a forum for discussion and revision between both academic and non-academic communities. With the sharing of the process of constructing history and knowledge, came the challenging dynamics involved in the representation of identity and history. In all of these groups - the arts, museology, and South African politics - the predominant issue seemed to be a negotiation between the bid to open up control to more parties, and the reluctance of some parties to relinquish control. While the emphasis is on significant changes that were implemented in the transitional period, the study locates the changes at the Johannesburg Art Gallery, the South African National Gallery and the Durban Art Gallery within their historical, geographical, and socio-political context. Various artists working in these locations during this era are also discussed, as the changes in their status, and the progressions in their subject matter, materials, and concerns are interesting to examine more nuanced definitions of the ‘political’, probing the politics of identity, sexuality, gender, race, geography, and belief systems. Some artists also focused specifically on post-apartheid preoccupations with territory, trauma, conflict, memory and freedom. This kind of artwork was assiduously acquired during the early ‘90s by public art galleries, whose exhibitions and collecting focus and policies were undergoing considerable revision and redress. This thesis examines these changes in light of their socio-political contexts, as well as in light of shifting national and international imperatives and conceptions of museums and museum practice.

- Description: Solvent-free reactions possess advantages compared to the solvent route, such as shorter reaction times, less use of energy, better yields, etc. Herein, the synthesis and characterization of bisferrocenylimines and arylbisamines are described. Reduction of the above compounds with LAH resulted in the formation of bisferrocenylamines and arylbisamines, respectively. The coordination chemistry of all the above compounds to rhodium(I) is also discussed in the prepared complexes [Rh(COD)(NN)]ClO4, where NN = bisferrocenylimines, and [Rh(COD)(NN)]BF4, where NN = bisferrocenylamines and arylbisamines. X-ray crystal structures of the complexes [Rh(COD)(NN)]ClO4 ([3.2] and [3.3]) have been obtained. Complexes of the type [Rh(COD)(NN)]BF4 were characterized with IR and UV-vis spectroscopy, cyclic voltammetry and conductometry. The catalytic activity of the complexes was also investigated: [Rh(COD)(NN)]ClO4 for the polymerization of phenylacetylene and [Rh(COD)(NN)]BF4 for the hydroformylation of styrene.

- Description: In Botswana, participation in environmental learning activities has been perceived as a central component of environmental education in formal education. Driven by the need to implement the objective of making the participatory approach part of the infusion of environmental education in the school curriculum as prescribed by the infusion policy, Botswana schools have come up with initiatives to involve learners in environmental education activities that seem to have ‘a direct, perceived benefit to the learners’ (NEESAP, 2007:9). Within this approach it is expected that learners should participate in these activities. However, Ketlhoilwe (2007) revealed that there has been a normalisation of environmental education into existing school culture through equating waste-management activities with environmental education. This generally entails cleaning activities by learners to maintain ‘clean schools’, which is directly associated with environmental education. Drawing from detailed case study data in one rural primary school with Standard 6 learners, I used Cultural Historical Activity Theory to investigate and explain how learners participate in these waste-management activities. Findings from this study revealed that attempts by teachers to meet the policy imperative through prescription of rules, and ascribing roles to learners in waste-management activities, create tensions. This gave rise to an elusive object of learner participation, as the purpose for their participation in these activities is not clear.

- Description: The cancer stem cell theory poses that cancers develop from a subset of malignant cells that possess stem cell characteristics and has been proposed to account for the development of a variety of malignancies, including breast cancer. These cancer stem cells (CSC) possess characteristics of both stem cells and cancer cells, in that they have the properties of self-renewal, asymmetric cell division, resistance to apoptosis, independent growth, tumourigenicity and metastatic potential. A CSC origin for breast cancer can neatly explain both the heterogeneity of breast cancers and the relapse of the tumours after treatment. However, many reports on CSC in the breast are contradictory. There is variation with respect to how breast cancer stem cells should be identified, their characteristics and a possible lack of correlation between clinical outcome and breast cancer stem cell status of a tumour. These combined factors have made breast cancer stem cells a highly contentious issue. In this review, we highlight the progress in the analysis of cancer stem cells, with an emphasis on breast cancer.

- Description: The post-apartheid South African government inherited an economy characterised by a dichotomy between well developed and affluent whites and the underdeveloped and impoverished African blacks. This dichotomy was manifest in sharp divisions with regard to access to decent housing, health, education and transport just to mention a few, thus reflecting poverty, as a widespread phenomenon. Since 1994, the South African government has made major efforts aimed at addressing poverty, however, that poverty persists, despite the efforts, cannot be contested. One of the major challenges has been the disjuncture between policies at various spheres of government. This study examines the articulation between two spheres of government focusing on the Provincial Growth and Development Programme of the Eastern Cape and the integrated development plan of Amathole District Municipality. Currently not much research has been carried out in this area. This study illuminates various analytical and practical issues and hopefully provides a useful basis for improvement in the government’s declared commitment to poverty eradication. Triangulating qualitative and quantitative research methodologies, the study aimed to investigate the integration of the Provincial Growth and Development Program and the Integrated Development Plan and the contribution of these policy instruments towards poverty eradication in the Eastern Cape. A further aim was to analyse community participation in and knowledge of the PGDP and Amathole IDP and how they have been effective. This was an empirically grounded study, based on the use of a combination of data collection methods, analysis of primary and secondary sources of data including government documents, administering in-depth interviews to a range of informants within government, the community and a questionnaire survey of a sample drawn from members of the community in the Amatole District Municipality and, finally the use of Amatole district as a case study which was the major unit of analysis. The findings from the study revealed that there is a plethora of challenges confronting policy integration, often resulting in institutional paralysis and inertia. Such challenges vary from lack of capacity in local government, lack of political will, policy shifts, a plethora of legislation, competing if not conflicting priorities, nonattendance of Intergovernmental forums, lack of cooperation by sector departments, contradictions between legislation, policy inconsistencies, conceptual imprecision and conceptual blurring. Moreover, the neo-liberal ideology informing development planning not only in the province, but in South Africa as a whole as propagated by western main stream economists leaves benefits indeed merely ‘trickling down’ to the poor and not ‘pouring’, such that the transition in South Africa has been reduced to an ‘elite transition’. The research results confirm, as observed elsewhere, that experiences of several developing countries over the past decades do not appear to support the trickle down hypothesis. On the other hand, community participation is also stifled by lack of participatory spaces, poor participatory methodologies and structures which make participation difficult while the poor remain trapped in the vicious cycle of poverty. Real participation goes beyond ‘passive development objects’ and ‘recipients of development’ to ensuring that people are empowered to become ‘masters of their own development’ within the context of a participatory democratic developmental state. There is need for not only a thorough examination of the political use of the ‘local’, the ‘poor’ but even the very conceptualisation of participation and its methodologies for effective community participation to be realised. , Thesis (PhD) -- Faculty of Management and Commerce, 2009

- Description: The economic feasibility of stock enhancement of Argyrosomus japonicus in South Africa was investigated using a willingness-to-pay (WTP) survey. The pilot study provides a unique example of the use of the contingent valuation method as a valuation tool for a proposed stock enhancement programme. An increase in the cost of a recreational fishing permit is used as a potential vehicle of payment. The median value of the maximum that fishers were willing to pay for a recreational fishing permit was R155 (South African Rand) for frequent fishers and R100 for non-frequent fishers. Analysis showed that a fee of more than R100 excluded up to 50% of anglers from the fishery, but that a fee of R100 excluded only 28% of recreational anglers and would generate an additional R12 million annually from the sale of recreational fishing permits. The estimated costs of set-up and running of a stock enhancement programme are substantially lower than this, suggesting that stock enhancement may be an economically feasible management option that deserves more investigation. The WTP method itself produces robust results and is likely to be an effective tool in the management of the marine environment.

- Description: Alcohol abuse is a very common practice (just like in many other parts of the world) in Nkonkobe Municipality, Eastern Cape Province, South Africa. This is associated with liver disease. An ethnobotanical survey of plants used for the treatment of alcohol-induced liver damage in Nkonkobe Municipality was conducted. During the survey and also from information gathered in the literature, Pelargonium reniforme Curtis, was prominently mentioned, among other plants, as the species used generally for the treatment of alcohol-induced liver damage. This project was designed to evaluate the effects of the plant on alcohol-induced liver damage, including its antioxidant and antimicrobial properties. It also involves safety evaluation studies to determine if the plant is safe for consumption. Studies using rats of the Wistar strain were carried out to determine the protective and curative effects of P. reniforme on alcohol-induced liver damage. Results obtained showed that the plant extract can protect the liver cells as well as enhance recovery from tissue damage. The plant also showed good antimicrobial and antioxidant activity and this further validates its use in the treatment of liver diseases. Safety evaluation studies of the extract were carried out by investigating the effects of the oral administration on some haematological and biochemical parameters in male Wistar rats. The results obtained from the study suggest that the plant extract is not toxic at the doses used and is therefore safe for medicinal uses. The results of the various bioassays carried out in this project have justified the traditional uses of P. reniforme for the treatment of alcohol-induced liver damage.

Effects of marine reserves on the biology of rocky intertidal limpets along the southern coast of South Africa

- Description: Limpets are harvested by people in South Africa, but are selected in terms of species and size. The effects of marine reserves on the biology of commonly exploited (Helcion concolor and Scutellastra longicosta) and rarely exploited species (Cellana capensis and Scutellastra granularis) were investigated on the southeast coast of South Africa at two reserve and two non-reserve sites. For each species, a 4-way nested ANOVA was used to test the effects of month, reserve, site (nested within reserve) and area (nested within site and reserve) on population density, size structure and recruitment of these limpets. The data were collected monthly over 20 months. The overall results indicated a gradient of exploitation among species, S. longicosta was the most heavily exploited species and S. granularis the least exploited species. However, there was also a gradient of exploitation between reserves and non-reserves. Xhora was the most heavily exploited site while Nqabara was less heavily exploited. Of the two reserve sites, Cwebe had more poachers than Dwesa. In most analyses, the month x area (reserve (site)) interaction was significant. However, this was largely an artifact due to comparisons of areas in different sites and significant differences between areas within sites occurred in relatively few months. Densities were greater inside reserves for all species except C. capensis. For S. longicosta and H. concolor this was expected but not for S. granularis and the result possibly reflects its opportunistic exploitation in the absence of the preferred species or indirect effects of reserves. Commonly exploited species and the rarely exploited C. capensis clearly showed greater mean and maximum sizes in reserves but there were month/site (reserve) interactions. Months with significant differences between reserves and nonreserves in both mean and maximum sizes generally occurred more often for commonly exploited than rarely exploited species, but C. capensis showed the strongest reserve effect on maximum size. Interview surveys showed that, although not normally exploited, C. capensis is sometimes mistaken for H. concolor and this suggests that large individuals are unintentionally harvested outside reserves. There were no significant reserve effects on recruitment for any species. Although Xhora had the lowest densities and limpet sizes, it showed the highest recruitment especially for S. longicosta, suggesting that larvae can be transported far from where they are released and settle in non-reserve sites regardless of adult densities. Reserve as a main factor was not significant for the rarely exploited species, but there was a significant month x reserve interaction, with non-reserves having greater GSI values than reserves in most months. Growth rates were examined using individual tagging and cohort analysis. The two techniques gave different results, with individual tagging giving higher growth estimates than cohort analysis. Except for the territorial species S. longicosta, growth was higher in non-reserves and inversely correlated with population density. Mortality estimates using the Cormack-Jolly-Seber model indicated that the rarely exploited species had significantly greater capture probabilities in reserves while no significant reserve effects were observed for the commonly exploited species. Reserve effects on survival probability were significant only for S. longicosta, with reserves being greater than nonreserves and no significant effects for any other species. Enhanced survival in reserves was attributed to the effects of human exploitation. In theory, marine protected areas show increases in densities, sizes and reproductive output of exploited species, but the present results revealed that the efficacy of reserves depends on the status of the species, not only whether it is exploited or non-exploited, but also whether it is territorial.

- Description: The transformation of all spheres of South African government to a more effective and efficient administration became a priority after the election of the country's first democratic government in April 1994. An important aspect of South Africa's democratisation was the promise by the new government to improve the lives of the people of this country, and provide a better life for all the citizens of South Africa. One of the most effective ways of achieving this goal is generally accepted to be the proper management and strengthening of the local government sphere. Local government is the sphere of government that is closest to the people, and generally the performance of National Government is assessed through the performance of municipalities. In strengthening local government, various pieces of legislation were developed since 1994 to ensure that the objectives of Section 152 of the Constitution are achieved. As a result of these imperatives, the Department of Provincial and Local Government introduced a White Paper on Local Government on 9 March 1998, with a vision of working towards a new developmental local government system. Various statutes emanated from this strategic framework, such as the Local Government: Municipal Structures Act No. 117 of 1998, the Local Government: Municipal Systems Act No. 32 of 2000 and the Local Government: Municipal Finance Management Act No. 56 of 2003. These legislative enactments endeavour to ensure that the local sphere of government is managed more strategically than previously, and is responsive to the needs of communities. Municipalities are expected to deliver efficient and affordable services to the local communities, and failure to do so could result in the recent spate of violent protest that has been recently experienced in various parts of the country. In order to measure the extent of service delivery to the communities, and to assess whether the objectives named in the municipality's Integrated Development Plan (IDP) document are being achieved, municipalities are compelled to implement performance management for all members of staff, political office bearers and service providers, in terms of the Municipal Systems Act No. 32 of 2000. This thesis therefore looks at challenges faced by the Senior Management (i.e. Section 57 employees, Directors and Assistant Directors) in the implementation of performance management within the Nelson Mandela Bay Municipality, during the first five years of their term in office (i.e. Senior Management appointed after 6 December 2000 local government elections), and recommending performance management steps as well as performance management model that can be used to cascade performance management amongst all levels of staff. This thesis begins by introducing the subject of performance management, briefly discussing the demarcation of the research, the research method utilised, the historical background of performance management, as well as the current status of performance management within the municipality. The introduction of the topic is followed by a theoretical overview of the subject of performance management. This is followed by the discussion of the research methodology followed when conducting this research study. The findings are discussed in detail after the research methodology, giving a synopsis of what the interviewees disclosed during the interview process. The last chapter provides a brief discussion of the findings, and discusses the recommended performance management steps and performance management model, that can be used by the municipality to cascade performance amongst all members of staff.

- Description: Nursing lecturers are faced with the challenge to adapt their teaching styles and attitudes to accommodate the new nursing student that enters the nursing field. These students have expectations and demands which differ highly from past students. Another challenge for lecturers is the demands of a nursing curriculum. The students that commenced with the four year course during 2005 at the Port Elizabeth Nursing Campus experienced negativity with regards to their training. The objectives of the study are to explore and describe the training experiences of the fourth year student nurses of the Port Elizabeth Nursing Campus and to co-construct guidelines to assist nursing lecturers to gauge the understanding of students during their four years of nursing training. The participants used for the study were all fourth year nursing students. They had positive and negative experiences of their training during the four years. The negative experiences related to the demands of the curriculum, lecturers’ poor subject knowledge and insufficient material resources needed for their studies. Regardless of the negativity experienced, students encountered positivity with regards to lecturers’ attitudes. The researcher focused on a qualitative study using an explorative, descriptive, contextual and phenomenological approach. A semi-structured approach was adopted to obtain data. Once consent was obtained from the relevant authorities, four fourth year nursing students were interviewed. The interviews were conducted by an independent role-player within the Department of Health to ensure an unbiased approach. Guba’s model was used to assess trustworthiness and data was analysed. Ethical considerations were ensured throughout the research process. Themes and sub-themes were identified. Based on the research findings, guidelines were co-constructed to assist nursing lecturers to better understand nursing students during their training. The findings of the study will be brought to the attention of nursing lecturers and management personnel of the campus. It was concluded that nursing students need to be consulted on issues concerning their training and development before implementation, and that they be respected and cared for as students based on their human rights.

- Description: The study sought to establish the impact of using the local content policy in reducing television cultural influences on Mbare youth in Zimbabwe. It is assumed that television has ideological and hegemonic functions which have come to dominate the life styles of the youths on issues of dress styles, musical tastes and language, thus threatening and weakening the long established local cultures. Hence the Zimbabwean government’s local content policy was established to reduce influences of alien cultures. This study, therefore, sought to establish if Mbare youth cultures confirm or reject the imitation of television cultures with regard to dress styles, music tastes and language. In addition, the investigation aimed at establishing the feasibility of using the local content policy to reduce foreign cultural intrusions vis-à-vis globalisation challenges. The three theories utilised in the discussion of the influence of television on Mbare youth culture in this study include the cultivation theory, the theory of hegemony and the uses and gratification theory. A qualitative study was adopted to gather data using focus group discussions, questionnaires and semiotic analysis. The sample of the study consisted of 87 participants and 4 Youth.com programmes. The study revealed that television has ideological and hegemonic functions. As such, it tends to be a dominant influence on the life styles and culture of Mbare youths. The study also established that Youth.com influences youth culture through music. In Zimbabwe music has become the most influential aspect of Youth.com despite not being specified in the local content policy on television broadcasting. Furthermore, the study shows that the implications of globalisation on local television content are undermining government efforts to preserve local cultures through the local content policy. The primary reason for this has to do with the fact that Youth.com programme does not contain a higher quota of local content as stipulated in the policy. However, although the local content policy was viewed as a political gimmick, the the study revealed that it was necessary in view of youths’ vulnerability to television’s ideological and hegemonic influences. Nevertheless, in view of the loopholes revealed by this study, the policy requires to be revised to cater for all the essential cultural elements, such as, music, which are allowing alien cultures to penetrate local ways of life. For instance, the urban groove music has major impacts on the culture of Mbare youths.

Substantive equality and proof of employment discrimination

- Description: This dissertation is a journey through the legislative changes and case law in order to analyse and evaluate the changing nature of South African jurisprudence in respect of the notions of equality, discrimination and affirmative action and the manner in which these issues are proved and dealt with in our courts. It focuses firstly on the emergence of the post-Wiehahn labour laws and the developing jurisprudence concerning discrimination in South Africa towards the end of a long period of isolation from the international world. It witnesses the growing cognizance which was taken of international guidelines and their slow and gradual incorporation into our jurisprudence before the institution of the new democratic government, in the days when the country was still firmly in the grip of a regime which prided itself on its discriminatory laws. It also deals in some depth with the new laws enacted after the first democratic government was installed, especially in so far as the Constitution was concerned. The first clutch of cases dealing with discrimination which were delivered by the Constitutional Court and their effects on decisions of the labour courts thereafter, are dealt with in great detail, indicating how important those judgments were and still are ten years later. A special chapter is devoted to the Harksen case, still a leading authority on how to deal with allegations of unfair discrimination. Having traversed several of the judgments of the labour courts after Harksen, several observations are made in the conclusion of the study which, it is hoped, summarize the major areas of concern in respect of the task of testing claims of unfair discrimination arising in our Courts.
