African horse sickness (AHS) was reported in the south-western Khomas Region, central Namibia (22° 24.063´ S, 17° 01.791´ E; 23° 32.617´ S, 15° 53.870´ E), contrary to expectations that the arid conditions in the area would limit its occurrence. This prompted investigation into the occurrence of AHS in horses, a possible reservoir animal, the Hartmann’s mountain zebra (Equus zebra. hartmannae) and the occurrence of the Culicoides midge vector (Diptera: Ceratopogonidae) of the disease in the area. Questionnaires were used to explore the geographic characteristics of the study area, the occurrence of an expected AHS virus reservoir animal, E. z. hartmannae and AHS in horses in the study area. According to the questionnaire, rainfall patterns seem to follow topography of the area, where the north-east formed the higher rainfall (420 mm/a) high-ground and the south-western formed the lower rainfall (120 mm/a) pediment zone in the south-west. Cases of AHS occurred mostly in mid-rainfall zones. E. z. hartmannae were present throughout the area. They migrated from the southwest towards the north-eastern high-grounds during droughts, presumably along ephemeral river beds. E. z. hartmannae were sampled for blood and tissues and analysed for evidence of African Horse Sickness Virus (AHSV) infection by indirect ELISA, RT-PCR and virus isolation techniques. All useable samples tested positive for anti-AHSV antibodies. Viral RNA was demonstrated in 26% of all the zebra sampled. No viable viruses were isolated from these samples, however further research is required, as difficult sampling conditions may have yielded false-negatives. From 6 July to 21 September 2009, Culicoides midges were collected during the dry winter season in suction UV-light traps installed at five selected sites along a rainfall gradient. In 38 collections, a total of 9091 Culicoides individuals, representing 25 species were collected. The dominance of the proven vector of AHSV, Culicoides imicola Kieffer, varied in dominance from 94% near Windhoek with high altitude and relatively higher annual rainfall, to 12% at the site situated farthest southwest, with the lowest altitude and annual rainfall. From what was observed of the occurrence of AHS in horses, E. z. hartmannae and the distribution and abundance of the AHSV vector (Culicoides spp.), it was concluded that AHS can be maintained in the south-western Khomas Region even in the lowest mean annual rainfall zones. / Thesis (MSc (Environmental Sciences))--North-West University, Potchefstroom Campus, 2012

Uranium exploration and mining activities in Namibia have increased rapidly since 2003, which increase not only poses a significant impact on the country’s economy, but also on its unique and pristine natural environment. The nature and extent of the environmental impacts associated with uranium mining requires a sound environmental law and policy framework that regulates uranium activities, impacts and aspects during each phase of the project life cycle of a uranium mine. It also requires of authorities to establish and enhance environmental protection and sustainability during uranium mining operations and to ensure that all environmental impacts that inevitably occur as a result of uranium mining activities are addressed in a holistic and integrated manner during each phase of the project life cycle of a uranium mine. In order to do this the country must develop and maintain an efficient and effective environmental governance regime. Namibia’s environmental law and policy framework that regulates uranium mining does not cover the entire PLC of uranium mining. It is vital that the current loops in the country’s existing environmental regulatory framework be closed and that an efficient and effective environmental governance regime, as envisaged in this study, be established. This will enable the administering agents to actively promote and maintain the welfare of the people, ecosystems, essential ecological processes and the biodiversity of Namibia, as well as the utilisation of living natural resources on a sustainable basis to the benefit of all Namibians, both present and future, as pledged in the Namibian Constitution. / Thesis (LL.M.

Many patients suffer from dermatological diseases throughout the world. Literature about this problem is emphasizing that it is getting worse. Factors such as poor hygiene, poverty and diseases such as HIV/AIDS, have increased the prevalence of dermatological diseases in developing countries such as Namibia. Understanding the different dermatological diseases and studying their prevalence will aid in ensuring patients better quality of life. The aim of the study was to investigate the prevalence and medicinal treatment patterns of dermatological diseases in the private healthcare sector of Namibia, with special reference to Windhoek. The research methodology was divided into two sections, namely a literature analysis and an empirical study. The literature analysis has been done to ensure knowledge about dermatological conditions before the empirical study was started. The empirical study was divided into two phases and data were collected from the community pharmacy environment (Phase 1) and a dermatologist (Phase 2). A total number of 507 patients participated in this study. In the community pharmacy environment, data were gathered from dermatological prescriptions of general practitioners (Phase 1A) and from pharmacist-initiated therapy prescriptions (Phase 1B). The data collected from the dermatologist (Phase 2), were collected from patients files at the dermatologist‘s practise. Phase 1A indicated that urticaria (n=36) had the highest prevalence followed by eczema (n=28) and contact dermatitis (n=28). 49% of the patients that participated in this phase were seeking treatment for the same condition the second time. In Phase 1B, contact dermatitis (n=15) showed the highest prevalence with eczema (n=14) and urticaria (n=8) second and third respectively. 77% of the patients participating in this phase of the research study did not have a family history of the same dermatological diseases. Phase 2 indicated that the highest prevalence of dermatological diseases was acne vulgaris (n=30) and melasma (n=19). The treatment duration that occurred most often in this phase was 180 days. Over all, the data indicated that eczema was the dermatological disease with the highest incidence of 11.2% (n=57). Other diseases that played a significant part were acne vulgaris (10.5%), urticaria (9.0%), contact dermatitis (8.6%) and melasma (7.1%). Rare dermatological diseases such as Kaposi sarcoma showed relatively high prevalence (n=9). It was concluded that this could be due to the fact that the dermatologist consulted, had been the only dermatologist claiming directly from the government medical aid, and that most of the patients diagnosed with Kaposi sarcoma during this research study were government employees. Many dermatological diseases were not specifically defined or diagnosed, but still treated with topical corticosteroids which may suggest that the term eczema is undefined and easily used by different healthcare practitioners for dry-skin related conditions. It is concluded in this research study that the three most prevalent dermatological diseases in the private healthcare sector of Namibia are eczema, acne vulgaris and urticaria. These conditions are not considered to be life-threatening, but they do have a significant effect on the quality of life of patients. / MPham (Pharmacy Practice), North-West University, Potchefstroom Campus, 2014

The objective of this study is to conduct a critical evaluation of the Namibian law and policy framework that currently regulates small-scale mining in Namibia. The discussion begins with an introduction to small-scale mining in Namibia which deals with the practice of small-scale mining, inter alia, as far as it is defined and the possible affects thereof. Small-scale mining affects various second generation rights of persons directly involved therein as well as the community as a whole. These rights include child labour; unemployment; gender issues; public health care; occupational health and safety; access to finance; poverty alleviation; and access to mining tools, machinery, markets and buyers. The law and policy framework applicable to small-scale mining in Namibia is accordingly critically discussed in terms of the strengths and weaknesses of the current framework. It is found that small-scale mining is quite well regulated in Namibia, but the current law and policy framework is not without its problems. Some of the main weaknesses identified are the centralised nature of the application for and pegging of claims, the lack of formal provision and regulation of the off-set markets, and the lack of access to finance for smallscale miners. Recommendations are made, such as that regulatory measures should be put in place to make provision for and to regulate the off-set markets for the minerals being mined by the artisanal miners. At the end of the study further research topics which relate directly to the regulation of small-scale mining in Namibia are identified. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

Sexual abuse of children and adolescents has reached pandemic proportions in Namibia. It is widely recognised that this traumagenic experience could have a profound and long-lasting effect on survivors. Nevertheless, few survivors in Namibia access therapy; often because of non-disclosure or non-reporting, being socioeconomically disadvantaged and the overburdened public sector therapists. This study set out to explore how adolescent survivors use the Nine Figure Picture Story (9FPS) embedded within the context of Gestalt Healing tasks. A variety of play therapy experiments was used to raise the clients’ awareness and to evoke their therapy stories (as these relate to Gestalt therapy) and their trauma stories (by means of the 9FPS). The researcher-therapist hoped that the study would enhance the understanding of the meaning-making of sexually abused adolescent clients, and in doing so, contribute to therapeutic practice in Namibia and elsewhere. Research which aims to uncover personal meaning-making and hear the voice of the participants already suggests that the qualitative paradigm would be apposite. An exploratory case study was conducted in Namibia between August 2010 and November 2010. Two adolescent survivors of sexual abuse who met the eligibility criteria were drawn from the population by means of nonprobability sampling. The sample was heterogeneous: one participant was a survivor of chronic intrafamilial rape; the other of a single incident, extrafamilial child sexual abuse (CSA). The data corpus included six and ten recorded therapeutic sessions with the two clients respectively; transcribed intake and termination semi-structured interviews with the parents; the researcher’s process and observation notes; and the clients’ objets d'art and Therapy diaries. To capture the tapestry of CSA accurately and holistically, the stories of the two participants were first analysed individually and thereafter synthesised into a theoretical comparative analysis. Trustworthiness was enhanced by means of investigator, theory, data and methodological triangulation. A number of safety, beneficence and non-maleficence measures contributed to the ethicality of this sensitive research. The research uncovered that, despite their differences, the two participants presented with posttraumatic signs and patterns often reported in the literature. Most insightful was how the survivors disavowed the CSA to become “not me” (Joyce & Sills, 2006: 92). As it relates to neurobiological hypotheses, it was revealed that the tactile and visuospatial Gestalt play therapy, specifically the 9FPS, seemed to access and address the fragmented, non-sequenced and non-verbal trauma memory. It was found that the 9FPSs gave the unfinished business from the past a miniaturised dimension in the present and that the “differentiated unity” (Reynolds, 2005: 162) enhanced its assimilation into the self. / Thesis (M.A. (Psychology))--North-West University, Potchefstroom Campus, 2012

Mathematics achievement has received much attention in recent years and results have been presented after examining results from different counties. This contribution deals with the implementation of new Mathematic promotion requirements in Namibia. The research was conducted in Shambyu circuit, Kavango region, within a selected combined public school situated fifteen kilometres from Rundu in the North-Eastern part of Kavango. Teachers and learners in Namibia have not performed well in the Southern and Eastern Africa Consortium for Monitoring Educational Quality (SACMEQ) projects, especially in Mathematics. The implementation of new promotion requirements was inevitable for improving achievement levels. The main aim of this study is to document the attitudes of teachers and learners towards the introduction of the new 2010 Mathematics promotion requirements. The complexity and the nature of attitudes are illustrated and some of the characteristics related to teaching and learning of Mathematics in the academic reform are presented. The researcher developed a conceptual framework to compare and contrast the theoretical positions on the topic. Attitude is defined from diverse perspectives, and relationships of attitudes pertaining to achievement to perform in Mathematics are argued. A qualitative case study was the preferred method of choice. The participants were sampled according to a non-probability purposive sampling strategy. Five teachers, six grade 7 and six grade 9 learners participated in the study. The participants were interviewed to gain insight into how they formulated their attitudes towards the implementation of the academic reform. Focus group interviews were captured though audio recordings. Patterns, themes and categories emerged from the data analysis, suggesting that teachers and learners demonstrate positive and negative attitudes which affect their stance towards the new promotion requirements. Research findings were compared with the relevant literature to identify strengths and weaknesses as extracted from the attitudes of the participating teachers and learners which confirm that attitudes of teachers and learners interrelate and affect teaching and learning of Mathematics. Strengths and weaknesses extracted from the attitudes of the teachers relate to teaching strategies, pedagogical content knowledge and practical application of the subject. A weakness of the policy change is that the Ministry of Education does not sustain involvement. Teachers need support through workshops to increase their pedagogical content knowledge and gain more information about the implementation of the new policy. Furthermore teachers expect educational support from the Ministry of Education through the provision of textbooks and teaching aids. Collaboration between teachers is crucial, as is the significance thereof for developing pedagogical content knowledge for the implementation of the new Mathematical policy. Strengths and weaknesses extracted from attitudes as viewed by learners in grade 9 are more related to their opinions about the teachers, their motivation and academic achievements. Learners’ natural Mathematics skills should be developed to instill feelings of accomplishment. Grade 9 learners experience fear and insecurity in Mathematics because learners experience teachers as too strict, owing to the absence of pedagogical content knowledge. The grade 9 learners distinguish the importance of ICT use in Mathematics as part of a process to prepare them towards greater goals and practical application as a strength. Both advantages and disadvantages of beliefs regarding Mathematics amongst the teachers and the learners guide grade 7 learner towards achievement. Further expectations drive the grade 7 learners towards achievement in order to increase career opportunities and level of schooling. In conclusion the in-depth qualitative exploration is summarized in order to investigate the phenomenon of attitudes towards Mathematics and academic reform. / Thesis (MEd (Mathematics Education))--North-West University, Potchefstroom Campus, 2013.
