- Description: Information Technology (IT) is growing rapidly and has become an integral part of daily life. It provides a boundless list of services and opportunities, generating boundless sources of information, which could be abused or exploited. Due to this growth, there are thousands of new users added to the grid using computer systems in a static and mobile environment; this fact alone creates endless volumes of data to be exploited and hardware devices to be abused by the wrong people. The growth in the IT environment adds challenges that may affect users in their personal, professional, and business lives. There are constant threats on corporate and private computer networks and computer systems. In the corporate environment companies try to eliminate the threat by testing networks making use of penetration tests and by implementing cyber awareness programs to make employees more aware of the cyber threat. Penetration tests and vulnerability assessments are undervalued; are seen as a formality and are not used to increase system security. If used regularly the computer system will be more secure and attacks minimized. With the growth in technology, industries all over the globe become fully dependent on information systems in doing their day-to-day business. As technology evolves and new technology becomes available, the bigger the risk becomes to protect against the dangers which come with this new technology. For industry to protect itself against this growth in technology, personnel with a certain skill set is needed. This is where cyber security plays a very important role in the protection of information systems to ensure the confidentiality, integrity and availability of the information system itself and the data on the system. Due to this drive to secure information systems, the need for cyber security by professionals is on the rise as well. It is estimated that there is a shortage of one million cyber security professionals globally. What is the reason for this skills shortage? Will it be possible to close this skills shortage gap? This study is about identifying the skills gap and identifying possible ways to close this skills gap. In this study, research was conducted on the cyber security international standards, cyber security training at universities and international certification focusing specifically on penetration testing, the evaluation of the need of industry while recruiting new penetration testers, finishing with suggestions on how to fill possible gaps in the skills market with a conclusion.

- Description: The Kumasi Basin in South-west Ghana lies at the centre of the best-endowed Paleoproterozoic gold province in the world. The Kumasi Basin and margins of the adjacent volcanic belts are host to six world class gold camps: (1) 62 Moz Obuasi camp, (2) 22 Moz Prestea-Bogoso camp, (3) 11 Moz Asanko Gold Mine camp, (4) 9 Moz Edikan camp, (5) 7 Moz Bibiani camp, (6) 5 Moz Chirano camp, as well as several additional minor gold camps and many more prospects. Cumulatively these camps account for>116 Moz of endowment and contribute to making south-west Ghana the greatest Paleoproterozoic gold province in the world. Gold deposits in the Kumasi Basin are shear zone hosted and mineralisation ranges from disseminated to massive sulphide refractory deposits, to free milling quartz vein style deposits. Structural relationships and age dating indicate that most deposits are genetically related and were formed during a single episode of gold mineralisation during the D4 NNW-SSE crustal shortening deformation event of the Eburnean Orogeny (2125 – 1980 Ma). The understanding of structural controls on mineralisation is critical for exploration success as it allows exploration to focus on areas where these structural controls exist. This study uses a mineral systems approach to understand the relationship between the geodynamic history and structural controls on gold mineralisation in the Kumasi Basin at various scales, and define targeting criteria which can be applied for the purpose of developing predictive exploration models for making new discoveries in the Asanko Gold Mine camp located in the Asankrangwa Belt. The study used a quantitative analysis to establish residual endowment potential in the Asankrangwa Belt, providing the basis for a business model and resulting exploration strategy. Once established, a Fry autocorrelation analysis was applied to identify trends in deposit and camp spatial distribution to which critical geological processes were ascribed. Observed trends were mapped from multi-scale geophysical data sets and through interpretation of existing geophysical structure models, and structural criteria for targeting orogenic gold deposits at the regional and camp scales were developed. Results show that different structural controls on mineralisation act at the regional and camp scale. At the regional scale the distribution of gold camps was found to be controlled by fundamental N-S and NW-SE basement structures with gold camps forming where they intersect NE-SW first and second order structural corridors. At the Asanko Gold Mine camp scale, deposit distribution was found to be related to the intersection between major second order D3 NE-SW shear zones, minor third order D4 NNE-SSW brittle faults, and cryptic NW-SE upward propagating basement structures. In addition to these structural criteria, deposits in the Asanko Gold Mine camp were found to be aligned along a NNE-SSW lineament caused by the interaction between the N-S basement structure and the NE-SW trending Asankrangwa Belt shear corridor.

- Description: This study explores the teaching and assessment practices used by teachers in environmental learning processes and emergent curriculum and sustainability competencies. The focus is the school subject Life Sciences in the Further Education and Training Phase. The study is based on four cases of teachers in schools in the Midlands area, in the province of KwaZulu-Natal. Lenses used to review the data included curriculum defined cognitive skills and cognitive levels to review the curriculum competencies and a systems approach to teaching and learning (Wiek, Withycombe, Redman & Mills, 2011) to review emergent sustainability competencies. This study employed qualitative methods, namely a questionnaire, stimulated recall interviews, observations (of lesson plan implementation in classrooms) and document analysis (detailing lesson plans, assessment tasks and learners’ work) to generate data. Analysis took place in four phases and included: a descriptive contextual analysis of factors influencing teaching and assessment practices; a descriptive analysis of teacher intentionality, topics, assessment planned and resources used; an analysis of emergent curriculum competencies in informal and formal assessment tasks; and, finally, a second layer of analysis describing emergent sustainability competencies in the environmental learning processes. Ethical considerations included permission for access, anonymity, participant rights and awareness of my role as cluster leader for the group of teachers involved. The study found that the nature of Life Sciences environmental topics and implementation influences the development of curriculum and sustainability competencies. Also, the choice of teaching methods influenced the emergence of particular curriculum and sustainability competencies. The findings also suggested that switching between isiZulu and English, unfamiliarity with action verbs, and the inconsistent use of higher order questions in classroom discussion, informal and formal assessment tasks might have affected success in the development of higher order thinking skills. Finally, the study revealed that environmental learning has the potential to support the development of integrated sustainability competencies. This study was driven by an interest in environmental content knowledge, teaching and assessment within the South African Fundisa for Change network of environmental educators. It is hoped that the study’s illustration of how consideration of curriculum and sustainability competencies can contribute to quality education practices in environmental learning, will be of use in this network.

- Description: The purpose of this study is to determine whether a discretionary inter vivos trust is still an effective instrument for estate planning. The process of estate planning, the role the trust plays in it and the background to the trust are described. The taxability and tax saving opportunities when the trust are utilised are discussed in the light of the Estate Duty Act, 45 of 1955, the Income Tax Act, 58 of 1962 (including the Eighth Schedule thereof) and the Transfer Duty Act, 40 of 1949. The opinions of tax and legal authorities in articles and relevant case law are also discussed. The impact of the "letter of wishes" on the stipulations of the trust deed is examined. Amendments to the Income Tax Act have placed a limit on the use of a trust for estate planning through a number of anti-avoidance measures, the introduction of a capital gains tax (in the Eighth Schedule) and the imposition of a high tax rate. The increase in the deduction granted in arriving at the dutiable amount of an estate, in terms of section 4A of the Estate Duty Act, from R1 500 000 to R2 500 000 has imposed a further limit on the use of the trust as an instrument in estate planning. The research demonstrates that, notwithstanding the amendments to the Income Tax Act, the trust still is a viable instrument, mainly because the trust operates as a conduit and because of its potential use in dividing taxable income amongst a number of beneficiaries. The stipulations included in the trust deed and the "letter of wishes" (if one exists), must be thought through carefully when estate planning is done, as it can give rise to the application of the general and specific anti-avoidance provisions as included in sections 7 and 103 of this Act. The research also concludes that, in assessing the effectiveness of the trust as an instrument in tax planning, the disadvantage of paying the higher transfer duty when the immovable asset is transferred to the trust should be weighed up against the possible saving in income tax and estate duty at a later stage. It is also clear that most assets owned by the trust are tax neutral, whilst many of the amendments under discussion deal with the taxability of trust income. The quantitative considerations underlying the use of the trust as part of the estate plan, remain unchanged. The research concludes by providing a framework of quantitative and qualitative criteria that can be used by an estate planner to determine whether it will be advantageous to transfer an asset to the trust to achieve the objectives of the estate plan.

- Description: The aim of this research project was to determine the effectiveness of DaimlerChrysler South Africa’s efforts in addressing the HIV/AIDS pandemic. The devastating impacts of the HIV/AIDS pandemic have already been felt at the workplace as without further successful interventions, HIV/AIDS mortality at DaimlerChrysler South Africa (DCSA) was expected to peak in 2006. Investment in HIV/AIDS programmes has been proposed as good business practice. The DCSA HIV/AIDS Workplace Programme was thus established to limit the impact and consequences of the HIV/AIDS pandemic on its workers, their families and surrounding communities. The empirical survey, comprising a questionnaire, examined the attitude and perception of employees regarding the effectiveness of the DCSA HIV/AIDS Workplace Programme. The findings of the empirical survey corresponded with the findings of the literature survey in concluding that the DCSA HIV/AIDS Workplace Programme has been successful in effectively addressing the HIV/AIDS pandemic. A few aspects of the Workplace Programme need attention and recommendations have been made in order to contribute to the lowering of HIV/AIDS prevalence rates at DaimlerChrysler South Africa.

- Description: The objective of the research was to determine the role which South African trade policy played in shaping the development of the domestic petrochemical industry. The focus of the study falls on the domestic development of the petrochemical industry in general, and the polymer industry in particular. Three broad stages are distinguished in the domestic development of the petrochemical industry. Prior to the early 1970's development occurred primarily on an ad hoc basis, with the establishment of domestic production plants for most major petrochemicals. The development of the domestic petrochemical industry over the period from the early 1970's to the early 1980's was characterised by rapid growth in the domestic production of petrochemicals, while the period from the early 1980's to the early 1990's saw a significant slowdown in the annual growth rate for the domestic production of petrochemicals. The role of trade policy in the industry's development over each of these three periods could not be established conclusively. In each period a number of factors were identified which may have impacted on the industry's development. However, two factors do appear to have played particularly important roles in the industry's development prior to the early 1980's, namely strong growth in domestic petrochemical demand and the provision of a substantial degree of protection through quantitative import controls and tariffs. with regard to the industry's development over the period from the early 1980's to the early 1990's, a number of factors were identified which may have influenced trends in domestic petrochemical production, including the withdrawal of quantitative import controls and the progressive lowering of import tariffs, the depreciation of the rand in the mid-1980's, a slowdown in the growth of the domestic demand for petrochemicals, the fall in the international prices of petrochemicals in the early 1980's, and the fall in the international oil price in the mid-1980's. In view of the small size of the domestic petrochemical market it is recommended that local petrochemical producers should continue to expand their focus beyond that of producing solely for the requirements of the domestic market. In light of the key role played by the petrochemical industry in a modern economy, it is also recommended that the industry in South Africa receive more attention from policy makers than it has in the past.

- Description: [From introduction] Exploration geochemistry is an indirect method of detecting mineral deposits by measuring the abundance and distribution of ore elements and elements closely associated with ore in natural materials at or near the earth's surface. The method relies on the assumption that a mineral deposit is reflected by unusual element abundances or distribution patterns (geochemical halos), and that these indications of mineralization can be detected by geochemical surveys involving the collection and analysis of natural materials. The interpretation of geochemical surveys in mineral exploration involves: 1) The use of geological and statistical inference, based on a knowledge of the normal behaviour and distribution of indicator elements in the exploration area, to recognize apparent geochemical anomalies in field and analytical data and to predict the type of geochemical halo reflected by the anomalies. 11) The use of geological inference, based on a knowledge of the characteristics of geochemical halos and their relationship to mineral deposits, to predict the presence and probable location of an ore body. The interpretation process is, however, complicated by the absence of a simple universal formula that relates the abundance and distribution of elements in natural materials to the presence or absence of a mineral deposit. The interpretation of a geochemical survey must, thus, be based on an empirical approach which avaluates each survey as an individual problem. The objective of this dissertation is to illustrate the factors affecting the "nuts and bolts" approach to the interpretation of geochemical surveys in mineral exploration. The discussion is aimed at providing field geologists responsible -for the planning and execution of geochemical surveys with some basic guidelines for interpreting the surveys. I hope that the contents of this dissertation will help field geologists to "look in the last place first".

- Description: [From introduction] Exploration geochemistry is an indirect method of detecting mineral deposits by measuring the abundance and distribution of ore elements and elements closely associated with ore in natural materials at or near the earth's surface. The method relies on the assumption that a mineral deposit is reflected by unusual element abundances or distribution patterns (geochemical halos), and that these indications of mineralization can be detected by geochemical surveys involving the collection and analysis of natural materials. The interpretation of geochemical surveys in mineral exploration involves: 1) The use of geological and statistical inference, based on a knowledge of the normal behaviour and distribution of indicator elements in the exploration area, to recognize apparent geochemical anomalies in field and analytical data and to predict the type of geochemical halo reflected by the anomalies. 11) The use of geological inference, based on a knowledge of the characteristics of geochemical halos and their relationship to mineral deposits, to predict the presence and probable location of an ore body. The interpretation process is, however, complicated by the absence of a simple universal formula that relates the abundance and distribution of elements in natural materials to the presence or absence of a mineral deposit. The interpretation of a geochemical survey must, thus, be based on an empirical approach which avaluates each survey as an individual problem. The objective of this dissertation is to illustrate the factors affecting the "nuts and bolts" approach to the interpretation of geochemical surveys in mineral exploration. The discussion is aimed at providing field geologists responsible -for the planning and execution of geochemical surveys with some basic guidelines for interpreting the surveys. I hope that the contents of this dissertation will help field geologists to "look in the last place first".
