Magister Educationis - MEd / This thesis investigated the potential role of indigenous healers in life skills education in South African schools. The main focus of this study was to explore how indigenous knowledge of traditional healers can contribute to the development of life skills education in South African schools. The research also sought to strengthen Education Support Services in the South African education system, in order to address barriers to learning. These barriers to learning are linked to health challenges such as substance abuse, violence, malnutrition and HIV/AIDS and many other health-related issues in school-going age learners. / South Africa

Philosophiae Doctor - PhD / This thesis investigates land reform coverage at the time of the land summit through quantitative and qualitative content analysis. Hard news reports, editorials and opinion pieces that appeared in the daily newspapers Beeld, Business day, Sowetan and Sunday newspapers Rapport and Sunday Times between July and September 2005 were analysed in terms of what they reported , issues that received little attention, portrayal of certain issues and sources used. The findings were used to make inference about the degree to which the newspapers in the study fulfill their societal roles. / South Africa

Magister Legum - LLM / An aspect of the South African law of trusts which has, despite the abovementioned evolution of South African trust law, not been clarified, is the ambit of a trustee's fiduciary duty. This, however, is not only the position in South Africa, but Scotland and, until recently, England as well. It is opined that the "fiduciary obligation" is a concept in search of a principle. Thus, the aim of the present research was to define this concept in terms of the South African trust law context. / South Africa

Philosophiae Doctor - PhD / Throughout the world, growing evidence suggests an increase of female migrants in migration streams. In the context of South Africa, women are not exempted from migration mechanisms. This new migration phenomenon is observed to influence housing accessibility among female migrants in the areas of destinations specifically in metropolitan and non-metropolitan areas of South Africa. Yet, little is known about the forms of housing tenure female migrants use to acquire a place to live in. The methods of housing acquisition of female migrants are still imperfectly documented. Moreover, it is not clear of how housing tenure differs among female migrants between metropolitan and non-metropolitan areas. Factors determining housing tenure and at what extent those factors are selective towards women in the places of destination are not properly elaborated in the existing body of knowledge. The aim of this research is to highlight the relationship between female migration and housing acquisition in South Africa by specifically looking at household headship in a gender perspective, and how housing acquisition differ between metropolitan and non-metropolitan areas of South Africa. It is assumed that inasmuch as migration is selective, so is a really differentiated selectivity of such places as metropolises and non-metropolises. This research makes use of the 2007 Community Survey secondary data derived from Statistics South Africa. The data analysis was carried out, first, by means of univariate analysis, cross-tabulation, and Chi-square statistical test for association. Logistic regression analysis was used in order to identify the determining factors of housing tenure among female migrants. The two groups of female migrants were considered namely: female migrants heading households and those who were not heading households. The units of analysis were metropolitan and non-metropolitan areas. This research focuses on internal female migration and housing in South Africa by examining different socio-demographic, socioeconomic, migratory, households, and housing attributes, by taking into account variables such as age, population group, marital status, level of education, just to name the few. By bringing together female migrants characteristics, migratory characteristics; and housing characteristics, the study found that female migrants heading households living in metropolitan areas are more likely to stay in rented dwellings, while those who were living in areas outside metropolitan (non-metropolitan areas) were highly represented in owned and fully paid dwellings. This study found further that, besides duration of residence, housing structure type, especially the availability of standalone housing type increases the likelihood of staying in owned and fully paid housing. This study concludes that, this new female migration stream creates more tension and pressure on housing provision in metropolitan areas in relation to non-metropolitan areas. Thus, policy makers should be aware of female migration and its impact in the housing sector in order to plan accordingly.

Ethnic identities in South Africa have had a particularly contrived history, set within the constraints and motivations of population classification by race. A more democratic political environment emerged with the dismantling of apartheid, bringing with it a multitude of issues including the design and character of the country’s political institutions and framework. This thesis will address two principal questions. The first and primary one investigates what lies behind the initiation and development of ethnic bonds. The second concerns the political implications and management of ethnic expressions in a democratic South Africa. An analysis of Zulu ethnic nationalism will be undertaken, because it constituted the most prominent case of assertive communal interests during democratic transitional negotiations. This thesis argues that circumstantial and instrumental factors (based on conditions, and the actions of individuals and organizations respectively), have been predominately responsible for the initiation and formation of ethnic bonds, especially amongst those who identify with a Zulu identity. The “conditions” describe the increasingly segregationist direction in which successive South African government authorities were moving, especially after the 1948 election victory of the National Party and the subsequent introduction of apartheid. Secondly, the “actions” denote the motivations of both Zulu actors and governments in generating and elaborating an ethnic discourse where their desired interests could be more effectively supported and assured. It will also be argued that because of the instrumental and selective use of ethnicity, as well as the narrow interests being served by its popular and community-centred expressions, a developing South African democratic culture should seek to protect ethnic diversity rather than promote ethnic interests. To do so would be to deny the perpetuation of ethnic cleavages and the violence and instability perpetrated in its name in recent years. The “protection” of cultural diversity is consistent with a constitution that seeks non-discrimination among all South African identities. Finally, it is believed that an emphasis on the individual as individual, as well as member of a cultural group, will break from subordinating the individual to an ascribed racial and ethnic identity as in the past, and assist in reconstituting the state as equally reflective of all South Africans.

Abalone Haliotis midae farming in South Africa is highly intensive, employing pump-ashore, flow-through systems. Despite the known sensitivity of abalone to water quality, there is only a rudimentary understanding of water quality dynamics on South African abalone farms and its effects on abalone production. Furthermore, the potential for reusing the relatively dilute abalone farm effluent to culture other animal species has not been investigated. This study investigated the dynamics of water quality and growth on a South African abalone farm and assessed the suitability of the effluent for the culture of silver kob Argyrosomus inodorus and bloodworm Arenicola loveni loveni. Monitoring of water quality and abalone growth in abalone tanks revealed that oxygen concentrations decreased, while H⁺ ion and free-ammonia (NH₃) concentration increased in a gradient between the inflow and outflow. Abalone growth was positively correlated with oxygen concentration and negatively correlated with free-ammonia and H⁺ ion concentration. The oxygen (O) concentration of the farm influent was dependent upon the influents’ temperature (T) and was described by the relationship O (mg L⁻¹) = 11.244 – 0.208T (r²=0.74). Linear regression analysis of data collected from abalone farm tanks revealed that the concentration of total ammonia at the outflow of abalone tanks (μg TAN L⁻¹) was dependant upon temperature (°C), flow-rate (L s⁻¹ kg⁻¹ H. midae), abalone size (g) and length of time since the tank was last cleaned (d) (n = 125, r² = 0.80). The production of total ammonia (μg TAN s⁻¹ kg⁻¹) was related to temperature, abalone size and days that the tanks remained un-cleaned (n = 125; r² = 0.81). A diurnal cycle of respiration was evident in abalone tanks with higher oxygen consumption and H+ ion production at night. The oxygen concentration of farm effluent was related to temperature, farm biomass and flow rate by means of a linear regression equation (n = 40; r² = 0.69). The results demonstrated the importance of optimising the flow-rate per unit of biomass for various temperatures and sizes of abalone. As abalone size and temperature cannot be controlled under farm conditions, the flow-rate per unit of biomass which the abalone culture system receives will determine the quality of the culture water. The specific growth rate (0.48 ± 0.01 % BW d⁻¹), mortality (1.8 ± 0.5 %), feed conversion ratio (3.0 ± 0.2) and protein efficiency ratio (1.0 ± 0.1) of silver kob kept in either abalone farm effluent or control seawater for 120 days did not differ significantly (t-test, P>0.05). A 90 day growth trial indicated that abalone farm effluent is a suitable culture medium for bloodworm. Bloodworm supplied with control seawater lost weight at 0.19 ± 0.04 % BW d-1, while those given abalone effluent grew at 0.39 ± 0.07 % BW d⁻¹. Mortality was 6 ± 3 % in effluent and 11 ± 8 % in seawater. The bloodworm were efficient at processing solid waste. Abalone farm effluent initially contained 7.7 ± 13 mg L⁻¹ more suspended solids than control seawater, which contained 3.5 ± 0.5 mg L⁻¹, but after passing through bloodworm systems the concentration in abalone effluent was reduced to only 1.4 ± 3.5 mg L⁻¹ above that in control seawater. Therefore, abalone farm effluent could be reused as a culture medium for both silver kob and bloodworm. Future work is needed to investigate aspects of the feasibility of such systems such as growth rates at different sizes and stocking densities.
