The settlement history of the Vredefort Dome can be described as a process of cultural development. The Vaal River hydrosphere, which was for many years a prestigious settlement site, initially attracted large scale game and later livestock farmers. The drifts were a central part of a network of early strategic communication routes and outspans. From 1838, pioneer settlement, farm occupation and agricultural development followed, and the area eventually entered an agriculture-mining era. Gold-mining stimulated the regional economy and also played a significant role in the development of towns in the area. The Vaal River did not play a significant role from a mining perspective, but featured more prominently in the development of villages and, in a sense, served as a political boundary. The location of the water source often determined where people settled permanently. It also decided the position of the house and yard. From the outset, riparian dwellers attempted to manipulate the flow of the river by creating dams and utilising water for irrigation and domestic purposes. Drought conditions also left historical traces; water management projects upstream transformed the Vaal River into a steadily flowing stream, which led to the economic and cultural segregation of north and south. Man's fear associated with drought (too little water), floods (too much water), meteorology (the necessity of water), and the role of the supernatural (divining water) and superstition (the water snake stories) were expressed in the interaction between people and this water environment. A wide variety of people with distinct cultures lived alongside each other in the area. Western and African cultural goods, as well as customs and beliefs, were mutually adopted by these different cultural groups as a result of this contact. The way land has been used in the Dome area has evolved over the years. The culling of game made way for the permanent establishment of the livestocktravelling farmer. Hereafter prolonged drought conditions destroyed pastures and, consequently, large areas of land were ploughed for agricultural use. Agriculture, which is more labour intensive and needs more water for irrigation, was replaced by game farming, which is less labour intensive and requires less water This world heritage site has drawn global interest and ecotourism has attracted visitors to the Vaal River area. The riparian dwellers, however, remain victims of up-stream industrial and sewage pollution; in future, they are likely to fall prey to acid mine water pollution, with disastrous consequences. / PhD (History), North-West University, Vaal Triangle Campus, 2013

Water resources in South Africa are scarce, and should therefore be protected against pollutants, also from persistent organic pollutants (POPs). This is emphasised by the Stockholm Convention on POPs, which aims at reducing and ultimately eliminating POPs. South Africa signed and ratified the treaty, and it became international law on 17 May 2004. POPS are highly stable, toxic, hydrophobic and lipophilic compounds, with the ability to accumulate in biological tissues. Previous research had shown that dioxin-like POPS are present in the aquatic environments of South Africa, with the highest concentrations of these substances measured in industrialised areas of South Africa. The present study aimed at investigating the extent of polychlorinated dibenzo-para-dioxin (PCDD), polychlorinated dibenzo-furan (PCDF) and polychlorinated biphenyl (PCB) pollution in the Vaal Triangle, by targeting aquatic sediments and biota. Sediment samples were collected from the Blesbok Spruit, Taaibos Spruit, Leeu Spruit and Suikerbosrand River, and fish tissue samples were collected from Blesbok Spruit and Suikerbosrand River, to determine bio-accumulation. The samples were extracted with organic solvents, cleaned-up and fractionated. Raw extracts and fractions were analysed with the H4IIE-luc reporter gene bio-assay. This bio-assay is a rapid, sensitive and relatively cost-effective method, which measures the effects of dioxin-like compounds on rat hepatoma cells, transfected with firefly luciferase gene. Selected samples were analysed with gas chromatographylmass spectrometry (GCIMS) to confirm results. Only one site had quantifiable amounts of dioxin-like substances in the sediment, measured to be 52.35 ng/kg [Effective Concentration 50 (EC 50)]. This value exceeds many of the European and USA quality guidelines, proposed for sediments. No dioxin-like substances were found in fish tissues. The absence of PCDD/Fs and PCBs in aquatic sediments and fish tissues from the Vaal Triangle area might be due to the climatic conditions of the area, dilution effects in streams, and degradation of these compounds by UV-radiation and microbial organisms. / Thesis (M.

The primary objective of this study was to identify and investigate the main restrictions automation suppliers encounter when attempting to promote and sell their products into the local Vaal Triangle manufacturing industry. Through the literature study that was conducted, a general investigation into the supply chains of some of the most prominent manufacturing industries within the geographical demarcation were analysed. Two manufacturing industries were chosen namely Sasol and Rand Water. The different criteria upon which they qualify their suppliers were identified and the reasoning behind it discussed. The identified criteria included product compliance restrictions; commercial restrictions as well as limitations placed on suppliers by the consumer themselves where suppliers are restricted to only a few per product or service. The commercial restrictions were identified as the only restrictions the supplier has total control over and for this reason, was investigated in detail. These commercial restrictions included the supplier's NOSA, ISO and CIDB rating, as well as their BBBEE status. After the literature review, an empirical study was conducted by making use of a questionnaire which was developed alongside the conduction of the literature study. This questionnaire was sent out to the top management of the identified local automation suppliers to be filled out. The completed questionnaires were analysed by the Statistical Consultation Services of the North-West University (Potchefstroom campus). After the reliability and validity of the questionnaire had been determined, the basic demographical information of the respondents was analysed. An assessment of the 12 constructs measured in the study was done and the relationships between the demographic variables and the constructs were identified. Following the detailed analysis, conclusions on the demographic information of the respondents as well as between all the demographic variables and the constructs measured which had practical significance were discussed. Practical recommendations regarding compliance to the commercial restriction studied were made. The success of the study was determined mainly based on the achievement of the primary and secondary objectives. The study concluded by making suggestions for further research on the topic at hand. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2011.

The shifting focus in the role of academic libraries entail a better understanding, awareness and responsiveness to the needs of the library users. In an environment of change and an age of accountability academic libraries have to determine and demonstrate the impact their resources and services are having on their institutional mission. Service quality is not based exclusively on the perception of the librarians, but also dependent on the perception of users. Only customers judge quality; all other judgments are essentially irrelevant" (Zeithaml, Parasuraman, Berry 1999). The reason of this study was to assess quality in the library and to determine the perceptions of the Vaal Triangle Campus Library users as they relate to quality service and to develop a model to improve service quality. The aim was to determine library users' minimum expectations for services, their desired level of service and then to identify the extent of service they currently perceive on three dimensions of service quality: affect of service, library as place and access to information. A triangulation, mixed method research methodology was employed in this study. Data was collected using focus group as well as individual interviews and the LibQUAL questionnaire. Purposive sampling was used to determine participants for the interviews while a total market survey was employed for the questionnaire respondents. Findings indicate that there is a gap between the users' expectations and perception of service quality. The results indicate that there are variations within the different user groups regarding the expectations and perceptions of service quality at the Vaal Triangle Campus library. In view of the findings, the study concluded by developing a service quality model based on Deming's PDCA cycle, the ISO model and the Hoshin Kanri process / Information Science / M. Inf.

The main purpose of this study is to determine the difference in water quality of the rivers between the Katse and Vaal Dams (Wilge River and Vaal Dam reservoir sub-catchments) after the construction of the Lesotho Highlands Water Project. These rivers include the Ash, Liebenbergsvlei and Wilge Rivers. The temporal changes in water constituents, namely: electrical conductivity, chemical oxygen demand, pH, turbidity, ammonia, calcium, manganese and chlorophyll a, at selected water sampling points were analysed to clarify if Katse Dam water has had any impact on the water quality of the Ash, Liebenbergsvlei and Wilge Rivers and the Vaal Dam. The water quality was studied over an eleven-year period from November 1994 until December 2005. This includes a five-year period prior to, and a six-year period following the completion of the Katse Dam. The Ash, Liebenbergsvlei and Wilge Rivers fall within the Wilge sub-catchment, and the Vaal Dam falls within the Vaal Dam reservoir sub-catchment. Both the aforementioned sub-catchments form part of the Vaal River catchment. Physical, chemical and microbiological sampling results were obtained from Rand Water. The results were compared with the in-stream water quality guidelines as set by the Vaal Barrage Catchment Executive Committee. The results of the selected constituents were depicted visually in the form of graphs. Trends in the constituents over the period were then determined. The graphs were divided into two sections namely, pre-Katse Dam (before 1999) and post-Katse Dam (1999 to 2005). Differences in water quality before and after the construction of the Katse Dam were determined from sampling and chemical analysis at six locations, and hence evaluations were made whether the release of Katse Dam water has had a significant effect on the water quality results in the Vaal River System. The water quality results with respect to the different water constituents illustrated a distinct change in water quality over the period. Northwards, towards the Vaal Dam, the difference in water quality became less apparent. Sampling points throughout the study area experienced decreases in: electrical conductivity, chemical oxygen demand, turbidity, ammonia, and manganese. Hence, the release of Katse Dam water into the Vaal River system has had a ii positive influence on the water quality and thus changed the riverine environments in the Vaal River system. The high quality water from the Katse Dam that enters the Vaal River system thus initially increases the quality of the water in the recipient system with a lesser effect downstream. The result is an improvement of water quality in the upper reaches of the Vaal River system and no significant influence on the Vaal Dam itself. However, the change in water quality may have a detrimental effect on the river environment as a result of the increased volume of water entering the system and the resultant soil erosion, which serves for further studies. Consequently, the advantageous high quality water from the Lesotho Highlands is not being optimally utilised, hence the proposed recommendation by Rand Water to alternatively transfer Katse Dam water via a gravity-fed pipeline to the Vaal Dam thereby receiving the full benefit of high quality water, leaving river environments unaltered and possibly lowering purification costs. / Prof. J.

Abstracts in English, Ndebele, Zulu and Venda / The study aimed to explore teachers’ experiences and to discover challenges encountered by mainstream teachers in the inclusion of learners with diverse barriers to learning in the Foundation Phase mainstream classrooms in the Vaal, Gauteng region. The study provides strategies that can be utilised by the teachers to enhance inclusive education practice in mainstream classrooms. Ten teachers were purposively selected from five mainstream primary schools with two participants from each school. All participants were grade three Foundation Phase teachers. Data were collected through in-depth interviews that enabled the researcher to delve deeply and find rich and relevant information for the study. For triangulation purposes, the researcher made use of document analysis as a second method of collecting data for this study. The study followed a qualitative data analysis method which derived the information from the perceptions of the informants and formed significant themes. The study revealed that teachers are challenged greatly by a lack of knowledge and skills to address diverse learning disabilities adequately; initial training that is ineffective in dealing with learners with diverse barriers to learning; a gap of knowledge that exists between theory and practice; a lack of adequate resources; poor infrastructure; large numbers of learners in a class; a lack of support from District Based Support Teams; and an inflexible curriculum. The study recommends collaborated teaching where teachers learn from each other; peer teaching; teacher exchange programmes; curriculum modification that caters for learners with barriers to learning; and workshop training that focuses on practical skills that will enhance inclusive education in mainstream schools. / Irhubhululo belinqophe ukuphenya ilwazi elihlangabezana nabotitjhere kanye nokuveza iintjhijilo ezihlangabezana nabotitjhere bomkhakha wefundo omkhulu lokha nakufakwa abafundi abaneenqabo ezahlukahlukeneko eziphazamisa ukufunda ematlasini weSigaba esisiSekelo (Foundation Phase) eLigwa (Vaal), esiyingini esise-Gauteng.

Magister Philosophiae (Integrated Water Resource Management) / Rare-infrequent magnitude floods of shorter duration events are significant natural hazards and play a key role in shaping river channel and island geomorphology. For a given river or channel, there is a relationship between the magnitude of a flood, frequency of a flood and duration of a flood, once a flood exceeds a reach-averaged erosional threshold geomorphic change can begin to occur. Expansion of conceptual models for the response of mixed bedrock alluvial influenced dryland rivers to such floods is of increasing scientific importance. The Vaal River near Parys in the Free State Province is characterised by a variable degree of mixed bedrock-alluvial anabranching channels which divide and re-join around the islands. In this study the historical aerial images and flow data from 1938 to 2016 were used to determine the effects of flood dynamics on island geomorphology in a large mixed bedrock-alluvial anabranching river: Vaal River near Parys. The historical aerial images and flow data reveals some minor island geomorphological changes during flood of rare magnitude, infrequent and shorter duration. The highest flood in the record was the one which was found having a recurrence interval of 20-50 years. The changes observed in the mixed bedrock-alluvial anabranching river in the Vaal River near Parys, indicate some minor decrease in the island bar area during flood of rare magnitudes, infrequent and shorter duration with recurrence interval of 20-50 years. The findings in this study area also reveals that the island bars in the area of study shows some degree of stability, however for the past 78 years the islands bar have not change the position. The impact of flood dynamics on island geomorphology in a large, mixed bedrock-alluvial anabranching river is not yet researched in the area of study (Vaal River), these findings will contribute to enhanced analysis of the Vaal River, relatively the impacts of extreme floods in island and channel geomorphology.

M. Tech. (Department of Visual Arts and Design: Fine Art, Faculty of Human Sciences), Vaal University of Technology. / My practice-based research aimed to produce commemorative portraits of black women in key positions who are associated with the Vaal Region. The study was undertaken in order to contribute to the empowering, positive and growing body of creative research on the visual representation of black women in the visual art field. My concern lies in the dearth of artistic representation of black women, particularly from the Vaal Region and with the hegemonic Westernised portrayal of black women in a Visual Arts discipline dominated by prejudiced attitudes towards issues of race and gender. This was accomplished in two steps. Firstly, through the examination of black feminist theories which underpin my theoretical framework, and further challenge and draw attention to the omissions, invisibility, non-recognition and negative portrayal of black women. In addition selected techniques in artworks of Zanele Muholi, Karina Turok, Sue Williamson and Bongi Bengu have been appropriated to create my body of work. Secondly, I utilise commemorative portraiture to produce iconic portraits of advocate Faith Pansy Tlakula, Professor Ntombekayise Irene Moutlana, Professor Kholeka Constance Moloi, Avitha Sooful, Lerato Moloi, Terry Pheto, Lira, Palesa Mokubung and the late mama Adelaide Tambo which were exhibited in the bodutu gallery accompanied by a catalogue and a comment book. Both of these methods are qualitatively explored as creative strategies to portray and award agency positively to black women through Third World readings of gendered perspectives.
