The rock engraving site of Driekopseiland, west of Kimberley in the Northern Cape is distinctively situated on glaciated basement rock in the bed of the Riet River, and has a wealth of over 3500 engravings, preponderantly geometric images. Most other sites in the region have greater proportions of, or are dominated by, animal imagery. In early interpretations, it was often considered that ethnicity was the principal factor in this variabilty. From the 1960s the focus shifted more to establishing a quantative definition of the site, and an emperical understanding of it within the emerging cultural and environmental history of the region.

Magister Artium (Social Work) - MA(SW) / The phenomenon juvenile delinquency is an enormous concern for communities in the ZFM district, Northern Cape, South Africa. Juvenile offences have increased since 2010 in this area. From existing theories, it is clear that the causes of this phenomenon are complex and interrelated. Some of these contributing factors are rooted in the character of the delinquent and his or her family. Other factors are peer, community or economic related. Against this background, it is clear that each community/area should be individually assessed concerning its contributing factors as these factors can differ from community to community, individual to individual and family to family. Thus, the research question: What are the psychosocial contributing factors of juvenile delinquency in the ZFM district, Northern Cape, South Africa? The research goal of this study was to determine the psychosocial factors contributing to juvenile delinquency in the ZFM region in the Northern Cape, South Africa. The objectives to arrive to the aim were to explore and describe the psychosocial factors contributing to juvenile delinquency in the ZFM region in the Northern Cape, South Africa and to make recommendations for interventions through probation services by probation officers and the Department of Social Development in the Northern Cape, South Africa. A qualitative approach was used, with an exploratory, descriptive design. Non- probability; purposive sampling was used to select probation officers from the Department of Social Development in the ZFM district in the Northern Cape. These Probation officers have each identified a parent of a juvenile in their caseloads. Because both parents of delinquents and probation officer’s perceptions are shaped by their own context, social constructivism was used as theoretical framework. Data was collected by semi-structured interviews with a checklist. The spiral for data analysis was used to analyse data, which was then clustered in themes, sub- themes and categories. Probation officers, participants identified a range of familial and community contributing factors to juvenile delinquency, and emphasises the interplay between these factors. Their also stressed the issue of parental control and guidance. Participants further indicated that harsh and ineffective parental discipline, lack of parental involvement, family conflict, child abuse and/or neglect and rejection by parents have also been identified as important factors related to delinquent behaviour. Another finding was that single parents, especially single mothers and the lack of a father figure are a great risk factor for juvenile delinquency. Parents also stressed the issue of their lack of control due to peer dependence and the juvenile’s involvement in alcohol and drugs. Probation officers also stressed the lack of parental involvement, continuous communication & parental guidance as some of the important contributing factors of delinquent behaviour amongst children. Parents also indicated a general lack of close relationship amongst family members, as well as emotional insecurity, and the inability to control their children. Both parents and probation officers agreed that peer pressure is a mayor risk factor concerning juvenile delinquency.

>Magister Scientiae - MSc / The Keimoes Suite is a group of poorly defined granitoids that characterize the Namaqua Front and Foreland zones. There is a lack of knowledge on its content and distribution. A significant amount of work has been done on the geochemical and geochronological aspects of the Keimoes Suite but no structural analysis using a comparison between joint occurrences in the suite and the country rock has been found in the literature. This study provides insight on whether these joints formed as a result of the emplacement and subsequent cooling of the granitoids or whether they are the result of later deformation processes. This was achieved through remote sensing, detailed field mapping and structural analysis of joint data to determine the type of stress regime associated with their deformation. Eleven granitoids of the Keimoes Suite were mapped in the Kakamas-Keimoes area in the Northern Cape, South Africa. Up to four joint sets were mapped and characterized according to orientation, abutting relationship, in-filling material and spacing properties. The orientation analysis revealed two prominent joint sets (NNW and NE) that are consistent throughout the Keimoes Suite granite. However after careful analysis of their abutting relationship it has been concluded that these joints are the youngest joints formed in the Keimoes Suite. The fourth set is the E-W set which does not occur at a wide spread scale. The oldest joint set (NNE) is defined by the quartz and feldspar filling and these joints only occur in the oldest granite of the suite. Field observation revealed shear displacement, forming a conjugate joint set. This conjugate set closes at an acute angle of 60˚ and the joints displace each other. The presence of en echelon sigmoidal veins suggests these joints formed as mode II fractures and that they are tectonic joints. The dominant joint set NNW is parallel to the regional foliation, shear zones and faults which were formed during the D2 deformational vent of the Namaqua Orogeny. This NNW joint set post-dates the D2 deformational event and was formed during the D3 deformational environment of the Namaqua Orogeny. Principal stress analysis of all the joints in the study area suggests a strike-slip environment, which coincides with the D3 deformation event of the Namaqua Natal Province. Even though the country rock and the Keimoes Suite granites were subjected to same stress field during the D3 event, the analysis of principal stresses between the Keimoes Suite granites and the country rock reveals a slight difference in the orientation of the principal stresses. This is caused by the difference in competency between the Keimoes Suite granites and the country rock thus caused the refraction. In conclusion Structural evidence on various members of the Keimoes Suite indicates three episodes of intrusions with respect to the D2 Namaqua deformation event based on foliation and mineral filled joints. The Vaalputs Granite is pre tectonic relative to the main D2 deformation event and the thermal peak M2 metamorphisms, while Louisvale, Kanon Eiland and Klip Kraal Granites are syn-tectonic to these deformation events. The granites that lack foliation are classified as post-tectonic granites and these are the Keboes, Kleinbegin, Gemsbokbult, Colstone and Cnydas Granites as well as the Friesdale Charnockite. However the presence of foliation in some granites suggests that a compressional episode existed for a period of time and ended sometime before the onset of the post-tectonic granites. Therefore the D2 pre-dates the last episode of Keimoes Suite granite emplacement. This study partly validates the work done by previous workers on the Keimoes Suite, although there are some slight differences which are subjected to change. Conclusion can be drawn that this study provided additional insight in the findings of other workers nonetheless also differs with some of their findings regarding the timing of emplacement of the Keimoes Suite.

D.Phil. / The Ongeluk Formation is a laterally extensive sequence of ≈2200 Ma tholeiitic basaltic andesites in the upper Griqualand West Sequence of the northern Cape Province. The stratigraphic thickness is about 500 m and the Ongeluk Formation underlies the ore-bearing strata of the Kalahari Manganese Field. The formation comprises massive lavas, pillow lavas and hyaloclastite beds in close association. These rocks were extruded under water in a marginal basin within the continental setting of the Kaapvaal Craton. The Hekpoort Basalt Formation of the Transvaal is magmatically cogenetic with the Ongeluk, having indistinguishable geochemistry and sharing a stratigraphically related hiatus in Cr values. The best age estimate for the two formations is 2193 ± 71 Ma, from Rb-Sr data of two previous workers for Hekpoort samples. The Ongeluk Formation shows a mild "regional" geochemical alteration and a profound "Kalahari" alteration beneath the Kalahari Manganese Field. Geochemical screening was used to reconstruct the magmatic composition from a selected dataset. Three stages in the development of regional alteration are ascribed to sea water-rock interaction at different temperatures, and have distinct geochemical signatures. The pervasive Kalahari alteration is characterised by a purple colouration and the decoupled alteration of alkali and high field strength elements. It is due to the development of major hydrothermal systems close to a volcanic vent which are analogous to modern mid-ocean ridge systems. A multi-system isotopic study showed that most of the isotope systems were modified by sea-floor alteration. The similarity of the 2237 ± 23 Ma Pb-Pb errorchron age with the Rb-Sr Hekpoort age reflects changes in U-Pb ratios with minor changes in Pb isotope ratio. Evidence was found in the Rb-Sr system for a minor disturbance at ≈ 1100 Ma, also reported by previous workers. This event is related to the Namaqua tectogenesis, while no isotopic evidence was found for the enigmatic ≈ 2200 to 1750 Ma Kheis orogeny, regarded as the cause of thrust faulting in the region. A genetic connection between the Ongeluk lava and the Kalahari Manganese deposits was established. The manganese ores contain evidence for both marine and hydrothermal contributions to chemical sedimentation. Negative Ce anomalies characterise an oxygenated sea in which the interaction between global oceanic and continental influences is seen. Heavy rare earth enrichment reflects volcanic hydrothermal exhalations from the Kalahari Ongeluk system. Mass balance calculations show that the entire 9 billion tons of Kalahari Manganese ore could have been derived from the Ongeluk Formation. A new model describing the origin and evolution of the Kalahari Manganese Field places a strong emphasis on the role of the syngenetic hydrothermal exhalation and upgrading.

<p>Dental caries is a multi-factorial disease that affects everyone irrespective of race, class or gender, however, the burden of the disease is often found in children from lower socio-economic backgrounds. The nature of the disease is such that it can be prevented. Various international studies on fluoride have shown a reduction in the prevalence of dental caries. By using geographical information systems, oral health data can be linked to the fluoride levels and further analysis could be done to identify areas at risk of dental caries as well as show patterns in the distribution of dental caries. The aim of this study was therefore to assess the effects of different levels of fluoride on the prevalence of dental caries in selected towns in the Northern Cape and Westen Cape. It also examined the application of Geographical Information Systems (GIS) to oral health data.</p>

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2014. / The site of Canteen Kopje in Barkly West, South Africa, has provided the archaeological record with an invaluable collection of Earlier Stone Age artefacts. An alluvial deposit approximately 1km from the modern Vaal River, the site contains an abundance of artefacts. A 2007 – 2009 excavation in Pit 6 has provided an assemblage of over 15,000 artefacts that has been dated by cosmogenic nuclide burial method. Three distinct assemblages show technological changes through time of the earlier Acheulean industrial complex. The youngest industry, the Prepared Core Technology Assemblage, is dated to 1.2 ± .07 Ma and contains Victoria West prepared core technology. Beneath it is the Organised Core Assemblage which is void of Victoria West prepared core technology but contains cores that demonstrate more organised knapping techniques in the form of asymmetrical control. This assemblage is dated to 1.51 ±0.8 Ma. Finally, the underlying Basal Early Acheulean Assembage lacks both prepared cores and organised cores and is >1.51 Ma in age. The abundance of large angular clasts of andesite in the area made multiple knapping strategies effective for the manufacture of large flakes. A technological sequence in the knapping strategies has emerged in this excavation, from simple cores to organised cores and finally prepared cores. The older technologies clearly display the roots of prepared core technology in the asymmetrical control of the organised knapping methods. The overall success of the knapping strategies prior to the appearance of the Victoria West industry in the Canteen Kopje archaeological record creates questions as to why more complex strategies might have been implemented over time. Analysis of the assemblages from the Pit 6 excavation fails to provide a clear technological explanation within the empirical data as to why this change occurs. This research therefore argues that the Victoria West prepared core knapping strategy is a localized stone age culturally motivated knapping tradition.

The main millennium development goal is to eradicate extreme poverty and hunger in the world by 2015. South Africa is one of the countries that signed this pledge at the millennium summit in 2000. The Department of Agriculture, has initiated a number of projects to assist farmers and communities with reaching this goal. In the Northern Cape, the commercialization of goats is one such anchor project. The major activities of this project is to train farmers in applied and appropriate production practices, assist them with accessing markets and supporting them with improved livestock. The main aim of this research was to evaluate whether the project has achieved its outcome and whether this outcome, is having an impact on the livelihoods of the farmers involved in the project. After reviewing the literature on evaluation research and programme evaluation across time, the different paradigms and approaches, participatory methodology was used in this study. A case study approach was applied to evaluate the outcomes and effects of the training received by farmers, as part of the commercialization of goats programme. The results of the study proved that the training received by members of the Campbell Agricultural Co-operative Enterprises, changed their goat production practices. The training also had a secondary impact. Trained farmers were imparting (technology transfer) their acquired knowledge to other members of the co-operative. This appeared very effective as all members of the cooperative were farming more scientifically. These changes to the production practices had a positive impact on the livelihoods of the farmers, as their animals were of a better quality and they were able to sell their animals at different markets and for better prices. This has however not commercialized their farming operations as they are still faced with many challenges. These challenges are the lack of a proper marketing structure, access to financial assistance, proper infrastructure and adequate transport for the animals to mention a few. If the Department of Agriculture and Land Affairs is serious about assisting these farmers to move from the status of “emerging farmer” to “commercial farmer” they will have to look at addressing the problems experienced with financial access and access to adequate and appropriate transport.

Submitted as requirement of the degree of Master of Arts History, Faculty of Humanities University of the Witwatersrand, January 2012 / Griqua Philippolis (1824-1862) and Afrikaner Orania (1990-present) are explored in this thesis, according to a legal-history framework that allows for a comparative appraisal of their foundations. As I argue, property – specifically, property in land – helps us to understand sovereignty and the question of rights in the South Africa. As this thesis explores, both settlements were formerly home to prior inhabitants (the San in Philippolis; Coloured squatters in Orania), and these inhabitants had to be transferred away. Both communities emerged out of contested and dynamic political contexts – situations that would determine how they saw themselves and others. Land regulations were devised within these respective contexts, in direct response to specific external pressures and the demands of the market. Internally, both polities were tightly governed. Externally, to various institutions and individuals, both argued for their ‘rights’ – mainly rights to land and to special treatment – all the time. Indeed, in a way, this study is an historical exploration of the effective deployment of ‘rights talk’, and to that end, my argument carries across two centuries right up to the present day using Orania and Philippolis to do this. This thesis, then, is a study about land rights, and the different regimes that create and erase them, that acknowledge and ignore them; it is a local history of settler colonialism past and present, using two case studies to explore the continuities of South Africa’s ever-pertinent land question. / XL2018

This document consists of three sections, and they are the academic paper (section 1), literature review (section 2) and research methodology (section 3). The academic paper consists of the purpose of the research, the summarised literature review, summarised research methodology and the research findings. The literature review section is a detailed review of literature used in this study. The research methodology section explains the research methodology and design which was employed in this study and it gives more details than the summarised version of the academic paper section. This summary integrated all the elements of section 1, section 2 and section 3. The purpose of this research is to identify the main problems that the Department of Environment and Nature Conservation (DENC) could encounter during the implementation and use of a performance management system, based on employee perspectives. The objectives of this research are therefore: to establish how often a particular problem has been encountered during the implementation and use of a performance management system in DENC; to identify the impact of various problems on the implementation of a performance management system, to establish whether these problems can be easily solved or not, and to analyse the problems associated with the implementation of a performance management system, as well as making recommendations for the successful implementation of a performance management system in the future. In this study, the researcher employed both quantitative and qualitative research approaches, informed by post-positivism as research orientation. The data collection techniques employed in this research include survey questionnaires and individual interviews. The survey questionnaire was answered by fifty respondents, and interview questions were answered by four respondents. The ethical issues were addressed by writing a letter to the Head of Department and getting authorisation to complete the research and informing respondents of their right to withdraw and to participate voluntarily. The findings indicate that the problems are either sometimes encountered or rarely encountered, and the division is about fifty percent of those sometimes encountered to those rarely encountered. This research indicates that most of the problems have a moderate impact on the use and implementation of a performance management system. The lack of management has a high impact, and a lack of positive attitude to performance management system (PMS) certainly has an impact on the use and implementation of the performance management system. Items such as the problem of information and communication technology (ICT) which does not support PMS adequately, and defining too many key performance indicators (KPI), have a small impact on the use and implementation of the performance management system. There are three problems which are difficult to solve and they are: lack of management commitment, organisational members‟ lack of positive attitude to the PMS and an insufficient period of commitment from management to PMS. This research indicates that most of the problems associated with PMS are moderately easy to solve. Two other problems that are easy to solve include the problem where there are too many KPIs defined and the problem where there is no organisational member appointed to take ownership of the PMS. According to this research, the top ten ranking problems have high ranking scores and this indicates that they can create major difficulties for the DENC in implementing the performance management system, and the chance of encountering these problems is high in the DENC in comparison to other problems. Almost all the problems ranked in the top ten seem to score highly in terms of the severity of their impact, and therefore this means that these are the problems which have an impact and, when they are not easily solved, they can become a tenacious issue for the organisation.
