  • Description: From Introduction: In geography during the 1950's there was a definite move away from the study of unique phenomena to the study of generalized phenomena or pattern (Mather and Openshaw, 1974). At the same time interrelationships between phenomena distributed in space and time became the topic of much interest among geographers, as well as members of other disciplines. The changing emphasis initiated acceptance of certain scientific principles (Cole, 1973), and mathematical techniques became the recognized and respected means through which objective analysis of pattern, structure, and interrelationships between a really distributed phenomena could be achieved (Ackerman, 1972; Burton, 1972; Gould, 1973). Geographers, as do members of other disciplines, frequently borrow mathematical techniques developed for problems encountered in the pure sciences and apply these techniques to what are felt to be analogous situations in geography.

  • Description: The HIV and AIDS crisis can be presented as a socio-ecological issue, with an ever-increasing impact on both human beings and the environment. Teaching about socio-ecological issues and the consideration of individual capabilities has become crucial within HIV and AIDS education programmes. Issues of deforestation, land degradation and other environmental problems have worsened since the advent of HIV and AIDS, especially in developing countries. The My Future is My Choice (MFMC) programme has been identified as an important HIV and AIDS education initiative that caters for young people in Namibian secondary schools (Grades 8-12). One of the themes within the programme (Facing HIV and AIDS) is highlighted in this study. This study was constituted as a case study of one school in rural Omuthiya, in the Oshikoto region. The study investigated the opportunities for the integration of a focus on socio-ecological issues and risks, within the MFMC education programme. The study also investigated the way in which the program develops learners‟ capabilities to respond to HIV and AIDS related socio-ecological issues and risks/vulnerabilities. The study also presents the constraints and enabling factors influencing the implementation of the programme. This study used a qualitative, interpretive case study methodology. The research methods included the analysis of eight documents and nineteen semi-structured interviews, with the Programme Coordinator, the Programme Facilitator, the School Principal and with the programme participants. The analysis also included two focus group discussions with a group of learners; and two classroom observations; and the learners' submissions (reflection sheets). Convenience sampling was used, and ethical issues were taken into consideration throughout the study. The study revealed the following as key findings:  The aims and objectives of the HIV and AIDS education programme can enhance and constrain the development of capabilities, as well as opportunities and challenges for the integration of a focus on socio-environmental issues and risks as additional learning content.  Teaching and learning methods that are participatory and rooted within the learner centered approach can make the integration of HIV and AIDS inherent socio-environmental issues and risks into the MFMC education programme possible.  The values and beliefs inherent within the MFMC education programme stand as opportunities for the successful development of capabilities in the education programme. The study concluded by recommending that capabilities within the MFMC programme be developed through teaching learners about their rights, respect for human dignity, and the right to health and to living the life free from discriminatory practices, as a moral entitlement of each and every individual. While teaching learners about their right to health and the importance of healthy diets, this study found that the programme could include learning about food production and handling practices for the benefit of those living with HIV and AIDS, while caring for the environment. Another recommendation was that future research should consider actively involving young people in decision-making with regard to the programme, as this will allow them to choose and decide on what knowledge and skills they need and want to acquire. The study further explained that this will promote the programme participants‟ sense of agency, and their freedom to choose what they value being and doing as an important element in enhancing learner capabilities. Ultimately, this will also enable the learners to acquire the necessary skills and knowledge they need in order to respond to the socio-ecological problems they face in their communities.

  • Description: As a potential main player in the primary health care sector and the impending National Health Insurance (NHI), community pharmacists could make a significant contribution to easing the health care burden in South Africa. Recent legislative and organizational changes related to the corporatization of pharmacy in South Africa have impacted significantly on the profession and stand to weaken the already ‘tenuous’ professional identity of pharmacists in the country. Since community pharmacists are viewed as potential main players in the primary health care sector, the influence of corporatization on pharmacists’ identities and their concomitant ability to contribute to easing the health care burden in South Africa need to be considered. In this regard, this study examined the influence that corporatization has had on the professional identity of community pharmacists practicing in the Nelson Mandela Bay area of South Africa. That is, in an effort to understand the influence that corporatization has had on changing professional identities and practices the attitudes, beliefs, and behaviours of community pharmacists regarding the philosophy and practice of pharmacy were explored. This included ascertaining community pharmacists’ self-perception of their professional identity and the perception of users of these community pharmacies. The study was conducted from an interpretative epistemological paradigm, based on a philosophy of pragmatism. Data collection was conducted in two phases and a qualitative approach, which included in-depth and semi-structured interviews, was adopted as a design. Phase one investigated the self-perceptions of sixteen community pharmacists, equally distributed between independent and corporate pharmacies in the Nelson Mandela Bay (NMB). Phase two examined the perceptions of thirty-two end-users of the pharmacies included in the study. Data from both phases were then analysed and interpreted. Following the identification of seven core professional identities, namely pharmacists as custodian or keeper of medicines; primary health care givers; confidante and carer; jaded; astute and credible; corporate; and independent, it was determined that corporatization has, to various degrees, had an effect on the undermining of Nelson Mandela Bay community pharmacists’ view of themselves as skilled professionals in the health care sector. In short, it was found that corporatization is believed to have blurred the boundaries related to what it means to be a pharmacist and what role pharmacists should play in the provision of public health care. Corporatization does not appear to have influenced the patients’ or pharmacy end-users’ perceptions of the pharmacist, and furthermore does not play a major role in their choice of pharmacy. It is the perception of pharmacists in this study that with the introduction of legislative changes, more so corporatization, they experienced an undermining of their professional skill and disregard for costs involved in becoming a pharmacist. The perceived undermining of the professional skill of pharmacists threatens the valuable contribution that community pharmacists can make to balancing the country’s socio-economic status by appropriately and efficiently assisting in preventing, managing and/or reducing the disease burden in South Africa. Corporatization of the community pharmacy sector seems to have realized the government’s intention of making medication affordable to its citizens, however, the certainty of whether corporatization benefits patients that are in need of access remains to be seen. Community pharmacists could in fact, capitalize on the identification and enactment of their clinical skill (pharmaceutical and social caregiving) as this skill appears to be a tool that will allow pharmacists meaningful transition to being real contributors of primary health care in the imminent introduction of the NHI. At the same time, recognition of the role a pharmacist plays in primary health care will be supporting the government in its endeavours to making medicine accessible and affordable to all South African citizens without compromising their health needs. Ultimately, pharmacists can assist in the balancing and/or improvement of the socio-economic status of our society and the country.

  • Description: The mind and character of an individual can be fostered by the subjects which have proved themselves to be of value in improving the education of man, not only from scientific, but also from moral and aesthetic stand points. The question is whether or not geography as a subject fulfils this requirement. For this it must have a distinctiveness of aim and a limitation of content. Civilization today is passing through great crises. Wars, rumours of wars, cold wars, economic crises, exhaustion of natural resources etc. are reported daily in the newspapers. Education of a certain type is needed - an education which will develop in man a deep concern for the freedom and good life of his fellows, and some understarding of the major problems of the world and possible solutions. Man is no longer a unit of a small self-contained community, but has his responsibilities as a citizen, firstly of his own country and secondly of a world community. Upon his solutions to the problems of the world depend to some degree the progress and development of his town, country, of the world generally. Education therefore ought to train the child to take his place in the world, not only as a man, but as a citizen. Children must be taught to think and reason for themselves. Geography as a subject lends itself magnificently to the general education of men and the development of good citizens. Geography can help to teach pupils to understand and experience the adult world. South Africans are fortunate in that geography is a compulsory subject up to standard seven. In high school beyond this level it is not offered by all schools.

  • Description: Subtropical thicket supports a large variety of indigenous browsing herbivores, such as elephants, black rhino, kudu and bushbuck, but impala historically never occurred in the Eastern Cape. The aim of this study was to determine what impacts extralimital impala (Aepyceros melampus) have on subtropical thicket. The thicket of the Shamwari Game Reserve, Eastern Cape, was used for the study. To quantify the effects of impala, feeding behaviour and diet was investigated during summer and winter. Sixteen impala were also enclosed in a camp of subtropical thicket where they would be limited to feedings on thicket. Vegetation composition and structure were monitored for a period of 12 months in the enclosure. Impala followed the expected high percentage graze and a low percentage browse in thicket in summer. However, the expected was not observed during winter: at this time grazing and browsing were equally important. Field collection of feeding behaviour data showed that impala are attracted to fringes of intact bush clumps or degraded thicket. Analysis of the impala diet confirmed this, with a significantly higher percentage graze (48 percent) than browse (22 percent) during summer. However, during winter, diet analysis indicated grazing to be much higher (36 percent) than browsing (6 percent) with the impala temporarily taking advantage of nutritious grasses still present. The enclosed portion of thicket was originally at 80 percent ecological status but it showed significant changes after addition of 16 impala. Animal trails increased in number and in width, resulting in a trampling effect. Grass cover was significantly different inside the enclosure after 12 months compared to outside. The amount of available browse of the enclosed thicket was also significantly different after addition of the impala. It is concluded that impala have a negative effect on thicket, with trampling the most significant effect. Long term monitoring of the effects of extralimital impala in different types of thicket will be required to accurately quantify their direct effects on subtropical thicket in the Eastern Cape. The main aim of this study was to determine the impacts of impala on Thicket. The study showed significant impacts on Thicket as found in Shamwari, and therefore the aim of the study was achieved.

  • Description: Geomagnetically induced currents (GICs), resulting from adverse space weather, have been demonstrated to cause damage to power transformers at mid-latitudes. There is growing concern over possible GIC effects in the Southern African network due to its long power lines. Previous efforts to model the electric field associated with GICs in the Southern Africa region used a uniform ground conductivity model. In an effort to improve the modelling of GICs, GIC data together with Hermanus Magnetic Observatory geomagnetic field data were used to obtain a multilayered ground conductivity model. This process requires a definition of the network coefficients, which are then used in subsequent calculations. This study shows that GIC computed with the new network coefficients and the multilayered ground conductivity model improves the accuracy of GIC modelling. Then GIC statistics are derived based on the recordings of the geomagnetic field at Hermanus, the new network coefficients and ground conductivity model. The geoelectric field is modelled using the plane wave method. The properties of the geomagnetic field, their time derivatives and local geomagnetic indices were investigated to determine their characteristics in relation to the GIC. The pattern of the time derivatives of the horizontal geomagnetic field closely follow the rate of change of the north-south geomagnetic component rather than the east-west component. The correlation between the GIC and the local geomagnetic field indices was also investigated. The results show that there is a higher correlation between the GIC and the east-west components of the geomagnetic local indices than between the GIC and the north-south components. This corresponds very well with the orientation of the power lines feeding the power transformers at the South African Grassridge electrical substation GIC site. Thus, the geoelectric field driving the GIC at Grassridge is north-south oriented. Further, it is shown that the geomagnetic observation sites have a strong directional preference with respect to the Grassridge GIC site.

  • Description: Visualisation plays a central role in developing mathematical ideas because it can be used to make these ideas explicit and visible, and thus has the potential to advance understanding. This study centred around the GeoGebra Literacy Initiative Project (GLIP), a teacher development initiative in Mthatha that aimed to grow and develop appropriate Information and Communication Technology (ICT) skills in teachers, to harness the teaching and learning potential of GeoGebra. GeoGebra is a dynamic geometric software package that is very interactive and makes use of powerful features to create images which can be moved around the computer screen for mathematical exploration. This research project was located within GLIP and analysed how GeoGebra applets develop conceptual and procedural understanding in selected Grade 11 learners. One aspect of GLIP was for teachers to use GeoGebra applets that they had developed themselves and implemented in their classrooms in pre-determined cycles that were aligned to the curriculum. My study specifically focused on how the selected learners made use of these applets and explored how learning had taken place in terms of developing mathematical meaning-making. This interpretive research study was designed as a case study. The case was a cohort of selected Grade 11 learners who had been taught by GLIP teachers, and my unit of analysis was the learners’ interaction with the applets. A screen capturing software package was used to capture learners’ interactions with the GeoGebra. My data consisted mainly of recorded observations and interviews. An analytical framework derived from the works of Kilpatrick, Swafford, and Findell (2001) and Carter et al. (2009) guided and informed the data analysis of the learners’ activities with the GeoGebra. The theoretical orientation of this study was constructivist learning. An in-depth analysis and detailed descriptions of the participants’ interactions enabled me to gain a comprehensive understanding of their meaning-making processes in a technological classroom context. An analysis across the participants identified distinguishable patterns or differences in the development of the learners’ mathematical proficiency and making sense of mathematical ideas. The research argued that technology enabled visualisation was a powerful tool to not only enrich mathematically activities, but to also enrich conceptual and procedural understanding. The findings recognised that exploration of, or manipulation on mathematical objects in GeoGebra was a key activity in the participants’ meaning-making process. It also enabled learners to offer self-proclaimed theories

  • Description: This study focusses on the marine diamond placers within Exclusive Prospecting Licence 1950 and Mining Licence 103a, located northwest of the north-facing Hottentot Bay which is 60 km north of Lüderitz, along the central Namibian coastline. The thesis follows the natural geological evolution of the marine placer deposit from primary source, through alluvial and/or glacial transportation, concentration along the coastline by wave, aeolian and alluvial/sheet-wash processes and finally marine diamond placer preservation. All of these processes are reviewed as they are important in understanding of the evolution marine placer deposits. The poly-cyclic role of coastal aeolian, alluvial, and marine processes, in marine placer enrichment is shown to be particularly important in considered target identification and prioritisation. A detailed bathymetric, sonographic and seismic interpretation, is an integral part of diamond placer exploration, and was used to examine and describe surficial and sub-bottom characteristics within the study area. Marine placers are formed along palaeo-strandlines during periods of marine transgression and regression and are therefore fundamental in marine placer exploration. A detailed bathymetry map, compiled for this study, of the area between Lüderitz Bay and Clara Hill, provides the foundation for a detailed terrace level investigation. Regionally, twelve well-developed stillstand levels are identified, nine of which fall into the study area. These interpretations are compared with global eustatic as well as terrace and resource/reserve levels in the Lüderitz area and are found to correlate well. Sediment dynamic studies involve the use of accredited application software for wave refraction modelling, to determine the wave angle and orbital wave velocity at the seabed. Bedload velocities, required to move diamonds of specific sizes, can be empirically determined and therefore areas of diamond entrainment and deposition can be modelled and target features delineated and prioritised. These detailed interpretations provide a sound platform for evaluating diamond placer process models in the study area. By integrating both previously published and newly formulated ideas, a revised, holistic model for the formation of marine diamond placer deposits in central Namibian is postulated. The proposed model is tested by comparing it to the lateral distribution of presently defined resource/reserve areas in the Lüderitz area and shows a close correlation with most of these enriched deposits. Based on this model, a matrix for the delineation and prioritisation of marine placer deposits is developed and the best target features within the study area are identified. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in
