  • Description: Current trends in technology have led to a need for creativity and innovation in the design of contemporary digital products and systems. This has resulted in design thinking and creative design process having a higher profile in digital design practice. In turn, this has impacted computing education, by creating a need for computing students to develop creativity and design thinking skills. Creative design is taught using design studio teaching methods, which require a culture, environment and activities that are different to the teaching methods used in traditional computing education. Some computing academics have implemented courses using aspects of studio teaching methods, but no clear guidelines for a computing academic without creative design experience to fully apply studio teaching methods in courses could be found. The reason for the change in the role of design in the digital domain and how it affected the needs of computing students was investigated and a comparison of typical design studio and computing teaching methods was conducted using a learning systems model adapted for this specific purpose. This led to an identification of areas that required further investigation, or gaps in the knowledge of how to adapt design studio methods for use within a traditional computing education environment. These gaps were used as the basis for identifying a set of research questions for an empirical study. An exploratory case study was conducted at the Nelson Mandela Metropolitan University to answer the research questions. Three computing academics implemented studio teaching methods within three separate modules, following provisional guidelines devised from the preliminary research. Feedback was collected from the lecturers and the students registered for the modules regarding their experiences. It was found that it would be possible for computing academics to implement aspects of a design studio approach within the existing computing environment. An explicit teaching method, termed the computing studio teaching method, was developed from the results of the case study. This teaching method aims to provide computing academics with little or no creative design experience with explicit methods for implementing modified design studio teaching methods in order to promote creativity and design thinking within traditional computing modules. This teaching method will be tested, validated and refined in future research.

  • Description: Modelling ionospheric total electron content (TEC) is an important area of interest for radio wave propagation, geodesy, surveying, the understanding of space weather dynamics and error correction in relation to Global Navigation Satellite Systems (GNNS) applications. With the utilisation of improved ionosonde technology coupled with the use of GNSS, the response of technological systems due to changes in the ionosphere during both quiet and disturbed conditions can be historically inferred. TEC values are usually derived from GNSS measurements using mathematically intensive algorithms. However, the techniques used to estimate these TEC values depend heavily on the availability of near-real time GNSS data, and therefore, are sometimes unable to generate complete datasets. This thesis investigated possibilities for the modelling of TEC values derived from the South African Global Positioning System (GPS)receiver network using linear regression methods and artificial neural networks (NNs). GPS TEC values were derived using the Adjusted Spherical Harmonic Analysis (ASHA) algorithm. Considering TEC and the factors that influence its variability as “dependent and independent variables” respectively, the capabilities of linear regression methods and NNs for TEC modelling were first investigated using a small dataset from two GPS receiver stations. NN and regression models were separately developed and used to reproduce TEC fluctuations at different stations not included in the models’ development. For this purpose, TEC was modelled as a function of diurnal variation, seasonal variation, solar and magnetic activities. Comparative analysis showed that NN models provide predictions of GPS TEC that were an improvement on those predicted by the regression models developed. A separate study to empirically investigate the effects of solar wind on GPS TEC was carried out. Quantitative results indicated that solar wind does not have a significant influence on TEC variability. The final TEC simulation model developed makes use of the NN technique to find the relationship between historical TEC data variations and factors that are known to influence TEC variability (such as solar and magnetic activities, diurnal and seasonal variations and the geographical locations of the respective GPS stations) for the purposes of regional TEC modelling and mapping. The NN technique in conjunction with interpolation and extrapolation methods makes it possible to construct ionospheric TEC maps and to analyse the spatial and temporal TEC behaviour over Southern Africa. For independent validation, modelled TEC values were compared to ionosonde TEC and the International Reference Ionosphere (IRI) generated TEC values during both quiet and disturbed conditions. This thesis provides a comprehensive guide on the development of TEC models for predicting ionospheric variability over the South African region, and forms a significant contribution to ionospheric modelling efforts in Africa.

  • Description: This study is a critical analysis of child labour and human resource development in Uganda. The study was undertaken because of the growing concern about child-labour practices in African countries, Uganda being an example. The incidence of child labour and the form that it takes are driven by supply-anddemand factors countrywide, but also by the sheer need of children to survive. Child labour is considered to be a fundamental child development problem. Children are involved in a number of child-labour practices such as prostitution in the commercial and tourism sex industry, forced begging on the streets, and forced soldiering. They may be used as camel jockeys, domestic servants, farm labourers/herders, mine labourers, produce porters, roadside sellers/street vendors, sweetshop-industry labourers, cooks and porters for rebels. The persistent exploitation of children involved in hazardous work and conditions has become overwhelming in Uganda. Poverty as one of the major causes for the growing numbers of child labourers in the agricultural sector in Uganda has caused a number of children to engage in child-labour activities to earn extra income for household survival. Many children have opted for partial attendance in school, eventually dropping out. Parents have also frequently influenced children to work on family farms, thus contributing to the children dropping out of school. Child-labour practices have become entrenched in the social and moral fabric of Ugandan society, and for this reason, research endeavours to uncover ways and methods to reverse this situation. The main objectives of this research were to establish the impact of poverty on child labour, to assess the effect of the social and cultural setup on child labour, to find out the impact of child-labour legislation enforcement, to determine the 5 influence of the HIV and AIDS pandemic on child labour, to establish the effect of the educational system and technological advancement on child labour, to establish the level of awareness of human rights in the community, and to establish the impact of human rights activists on the prevention of child labour. The study was undertaken in Masindi District in Budongo Sub County, in three parishes, Nyabyeya, Nyantonzi and Kasongoire. The respondents used for the study included child labourers, their parents, farmers, and community leaders. The method used to get to the sample was purposive sampling. Data was collected using questionnaires for written answers and a tape recorder for oral answers. Both primary and secondary data was collected, verified, edited, checked, coded, analysed, and then exported to Excel and SPSS. Collecting the data was a challenging exercise for the researcher. Experiences were varied, in the hospitality and willingness of respondents to learn more about child issues. Although respondents were willing to participate in the data collection exercise, social and cultural values did not permit all of them to share their views with the researcher. To collect data from respondents, the researcher had to ensure that remuneration was in place at the end of the exercise. The respondents filled out the questionnaires only after learning of the availability of a reward for every questionnaire answered. More setbacks were the need to travel long distances, and enduring the poor infrastructure, poor sanitation, and epidemic outbreaks, some of which diluted the quality of data collected. During group interviews, most parents were not entirely truthful about involving their children in child-labour activities. Although most respondents had an idea of what child labour is, their ignorance levels on the topic prevented them from stopping their children from working. The major findings of the research were that the cultural, social and economic setup of the community in the study area favoured child labour, although the child-labour legislation is against using children as labourers. Various ethnicities 6 in the study area considered a person between the ages of 5 and 12 years to be a child, yet the Constitution of Uganda dictates the age of childhood to be below 18 years. This causes conflict in the definition of who a child is. Although parents were aware of the Universal Primary Education (UPE) regulation penalties for not taking children to school, they still permitted children to engage in child-labour activities, and little has been done by government to curb the culprits. Awareness of the Sub Counties and Credit Co-operatives (SACCOs) and their implementation has not helped to reduce poverty in the area studied, resulting in an increased school dropout rate among school-going-age children, as well as more child-labour activities. The major conclusion of the study was that little has been done to increase the awareness levels of the teachers, parents and their children about child labour and its legislation, their knowledge of and involvement in micro-finance institutions in the community, and the availability of vocational training institutions. Little has therefore been done to reduce child-labour activities, improve the economic status of the community, and improve their human resource skills. The major recommendations of the research to the study are that culture should not override the Constitution as far as the definition of age limit is concerned. The government should carry out stakeholder analyses, and implement a life-skills and sensitisation programme in order to improve child participation in the Universal Primary Education (UPE) programme. Government should ensure that the society is given information about basic accounting, project planning and management skills, in order to be effectively involved in the economic programmes of SACCOs.

  • Description: In 1998, South Africa introduced outcomes-based education to affect the shifts in pedagogy considered necessary following the move to democracy in 1994. Across the globe, the use of the portfolio to assess learners is increasingly being promoted as a form of progressive pedagogy. Hence, its adoption by the country as a new form of assessment practice was warranted. However, how the portfolio is constructed and perceived by educators within the classroom can become problematic in practice. This was apparent in the South African context and justifies research into how the portfolio is constructed as an assessment method in educational policy and by educators in the classrooms. The Curriculum Guide Directive text and the transcripts of twenty-one interviews carried out in three Eastern Cape schools served as the source of data for this study. Discourses make up a powerful framework of spoken, written and symbolic texts of institutional bureaucracies. Within these institutions human subjects are defined and constructed. Therefore, discourse construction acts as institutional forms of knowledge which can exude power over the individual if not made transparent. I used critical discourse analysis to uncover the discourses that were embedded within the Curriculum Guide Directive and to identify the discourses entrenched within the educators’ perceptions of the portfolio. The discourses in the Curriculum Guide Directive suggest the construction of the portfolio as a method of surveillance to track whether the educators are preparing learners for the school leaving examination and instructing the educators to provide evidence in the form of a portfolio. Analysis of the transcripts of the twenty one interviews with educators from three schools in the Eastern Cape indicated that the portfolio was not seen as a form of assessment by the educators, but as a form of discipline put in place by the Department of Education to ensure that they are preparing the learners for the school leaving examination and are able to produce proof of this preparation in the form of a portfolio. The discourses from the research highlighted that the school leaving examination is hegemonised into South African educational pedagogy as a form of traditional assessment and is not challenged even when it is no longer bringing about the dominant ideological goals. The portfolio was not seen as an assessment method by the educators nor represented as such in the Curriculum Guide Directive. Therefore, the job of the portfolio became that of a policing tool. Thus, a school curriculum which has been introduced with the intent of furthering social justice can become exclusive in practice, even with the best intentions.

  • Description: The South African motor industry plays a pivotal role in the economy of South Africa and is a leading indicator in economic change. In general, satisfaction of customer service in the motor industry is steadily improving. However, as research has shown, there is still room for improvement within the industry. Knowing what customers expect is a critical step in delivering good quality service to ensure customer retention in the long-term (Zeithaml, Parasuraman & Berry 1990:62-63). Having a good understanding of the value of forming long-term relationships with customers and their evaluation of the quality of the service provided, cannot be underestimated, as failure to actually ask customers what they think of the service could be detrimental in the long-term. Vehicle manufacturers conduct ongoing research to monitor customer perceptions of the quality of the service provided by their vehicle retailers. The information generated from the research findings can be used by manufacturers to improve levels of service where this appears to be lacking, and deal promptly with any customer complaints. Against this background, how vehicle owners judge the quality of the service provided by a franchised vehicle retailer for a repair and maintenance service, will be crucial to understanding how customers form perceptions of service related firms specifically, and in general, even an entire industry. The primary objective of this study is to assess customer perceptions of service quality with a franchised vehicle retailer following a routine repair and maintenance service. The sample consisted of 3 859 respondents who had their vehicles serviced at a GM South Africa franchised vehicle retailer over a one month period. The empirical results of the study revealed that GM South Africa show general positive results in terms of customer service satisfaction, however, there are some areas where additional attention is required.

A critical analysis of the distintion between mining and manufacturing for South African income tax purposes

  • Description: "Mining operations" and "mining" are defined in s 1 of the Income Tax Act (ITA). A concept that is of great significance to this definition is the matter of when a mineral is won and the related question of when does the mining process end and the process of manufacture commences. Case law has not established a definitive point that can be used by the mining taxpayer to determine where the mining process ends for income tax purposes. The Supreme Court of Appeal was presented with the perfect opportunity in the Foskor1 case to clearly define the boundaries between these processes. Unfortunately, the court did not seize this opportunity to provide legal certainty. The significance of the distinction lies in the fact that a mining taxpayer is allowed to claim accelerated capital allowances. The objective of these allowances is to provide tax relief to the mining taxpayer taking the immense risk of investing billions of rands in capital expenditure. The capital expenditure incurred will also result in direct foreign investment. This in turn will result in economic growth and job creation. Currently, there is no legal certainty as to which processes will qualify as mining operations for income tax purposes. This may result in mining taxpayers being hesitant to incur capital expenditure as the risk relating to a project would have increased. The accelerated capital allowances may therefore not serve their intended purpose. The gross domestic product (GDP) contribution from gold mining has been decreasing in the last number of years, but this decrease has to a large extent been offset by an increase in the downstream or beneficiated minerals industry. This industry has also been identified by Government as a growth sector. The downstream or beneficiated mineral industry may not be catered for in the current definition of "mining operations" and "mining" and may therefore not qualify for beneficial tax allowances. It is therefore proposed that the term "won" as used in the definition of "mining operations" and "mining" should be defined in s 1 of the ITA as follows: A mineral is "won" when all the requisite and necessary processes, including, amongst other things, refinement, beneficiation, smelting, separation, have been undertaken to the mineral to render it saleable in an open and general market. This extension will provide legal certainty to a mining taxpayer and will ensure that South Africa obtains direct foreign investment and maximum value for its minerals. This will contribute to economic growth for South Africa's developing economy and result in job creation.

  • Description: Over the last 10 years the South African fiscus has introduced numerous changes to the Income Tax Act (ITA) which affect the income tax implications of persons ceasing to be a resident of South Africa. The two main changes were: - The introduction of a world-wide basis of taxation for residents - The introduction of capital gains tax (CGT) as part of the ITA The aim of this treatise was to identify the income tax implications of persons ceasing to be a resident of South Africa. Resulting from this research, several issues in the ITA have been identified, and the two major ones are summarised below. Firstly, upon the emigration of the taxpayer, there is a deemed disposal of a taxpayer’s assets in terms of paragraph 12 of the Eighth Schedule. It is submitted that the resulting exit tax may be unconstitutional for individuals. It is recommended that South Africa should adopt the deferral method within its domestic legislation for individuals who are emigrating. The deferral method postpones the liability until the disposal of the asset. Secondly, on the subsequent disposal of assets by former residents where there was no exit charge in terms of the exemption under paragraph 12(2)(a)(i) of the Eighth Schedule. Depending on the specific double tax agreement (DTA) that has been entered into with the foreign country, taxpayers have been given vii the opportunity to minimise or eliminate the tax liability with regard to certain assets. This should be of concern from the point of view of the South African government. Further issues noted in this treatise were the following: - It is submitted that the term ‘place of effective management’ has been incorrectly interpreted by SARS in Interpretation Note 6. - It is further submitted that the interpretation by SARS of paragraph 2(2) of the Eighth Schedule is technically incorrect. The above issues that have been identified present opportunities to emigrants to take advantage of the current tax legislation. It is further recommended that taxpayers who are emigrating need to consider the South African domestic tax law implications, respective DTA’s, as well as the domestic tax laws of the other jurisdiction, not only on the date of emigration but also on the subsequent disposal of the respective assets.

  • Description: The automotive industry in South Africa exists in its current state due to the developmental programmes created by the South African government. During the next three years the government’s main development policy for the automotive industry will change from the Motor Industry Development Programme (MIDP) to the Automotive Production and Development Programme (APDP). As a result of this change there were feelings of uncertainty experienced across the domestic automotive industry during the APDP’s design and the period leading up to its launch, more or less years 2008 to 2010. Also present is the fear that the industry would collapse when faced with global competition should this change not fully comprehend all aspects of South Africa’s automotive industry. The research problem addressed in this study was to determine the effect on the sector’s competiveness in light of the impending change in governmental development programmes. This was accurately explained and expressed clearly while sub problems were identified from areas in the main problem that required further analysis due to their criticality or lack of clarity. A comprehensive literature review was executed to understand the nature and extent of the South African automotive industry, the Motor Industry Development Programme and the Automotive Production and Development Programme. A primary research instrument was constructed, in the form of a questionnaire, to test specific themes exposed during the literature review which can influence the sector’s competitive advantage. This questionnaire was distributed with the assistance of industry representative bodies NAAMSA (National Association of Automobile Manufacturers of South Africa, the domestic de facto representative body) and NAACAM (National Association of Automotive Component and Allied Manufacturers, a component manufacturers’ representative body), to an even spread of respondents representative of the senior management and executives of automotive companies in South Africa. From the results obtained from the sample group, it seemed that there was consensus on many issues regarding the current structure of the South African automotive industry. Specifically, the profitability of vehicle assemblers and component manufacturers is heavily iii influenced by the incentives offered under the MIDP and the industry is not viable without them. The respondents were virtually unanimous in indicating that there is a need for some form of incentive programme and were positive about the effect the MIDP has had thus far on the automotive industry of South Africa, particularly the effect on the structure, focus and encouraging a reduction in complexity. The research found that it is common practice for OEMs to include the import duty on vehicles imported for domestic consumption even though this duty will be paid with the use of import-duty rebate credit certificates (IRCCs), which are provided to those vehicle assemblers who are net exporters of vehicles. Looking to the future, it emerged that the APDP will have a similar, positive effect on the domestic automotive industry when compared to the MIDP, but the effect will be experienced in a more aggressive manner. Companies will be encouraged by the new development programme to more aggressively improve aspects such as restructuring, rationalising, reducing model proliferation and improving low scale economies for example. Also the APDP will encourage OEMs to increase plant production volumes and ensure that reasonable scale economies are present to develop a domestic component supply industry to a degree. However, the volumes will be insufficient to create a world-class supplier industry. As a result automotive companies will have to be more aggressive in their adoption of more automated production processes and through Automotive Investment Scheme capital investment will increase in both vehicle assemblers and component manufacturers. Component manufacturers indicated that they would invest more in the coming years under the APDP than previously while vehicle assemblers indicated that their investment levels will remain as before. While this is good for the industry, labour is somewhat left out of this: considering the APDP’s focus on increased volumes and capital investments automotive companies are not incentivised to make use of labour-absorbing production processes. The study also found that there is still a need for tariff protection and that the domestic industry would collapse in the face of global competition. The research found that the APDP was compliant with South Africa’s commitments to the World Trade Organisation. Finally, the Department of Trade and Industry’s goal of producing 1.2 million vehicles per annum by 2020 was revealed to be unrealistic and unreachable.

  • Description: On May 16 2006 the government of Zimbabwe embarked on a clean-up programme of urban centres, destroying informal human settlements and informal businesses. This operation, which the government called operation "Restore Order", resulted in the displacement of nearly one million people and left thousands of families homeless. This study is a discussion and an analysis of the coverage of the clean-up operation by two of Zimbabwe's leading Sunday newspapers, The Sunday Mail and The Standard. The Sunday Mail is owned by the Zimbabwe government and The Standard is privately owned and perceived to be oppositional to the current Zimbabwe government. The two newspapers, therefore, covered the clean-up operation from different perspectives and often presented conflicting reports explaining why the clean-up operation was carried out and the extent of its impact on the lives of millions of Zimbabweans. The chosen research approach is the Critical Discourse Analysis (CDA) framework as developed by Fairclough (1995). Using CDA, this study seeks to find out and expose the underlying ideological struggles for hegemony between different social and political groups in Zimbabwe and how the newspapers became actors in this process. This process is made possible by looking at how news reporting is organised in the two newspapers, issues of language use, sourcing and external factors that influenced the coverage of the operation.

  • Description: The Steiner/Waldorf school movement is currently one of the fastest growing independent school movements internationally. In several countries it seems to have developed into the most popular form of alternative education. South Africa has 17 Waldorf schools and one full-time teacher training facility. This study investigated the interpretation and implementation of the Parzival main lesson within the wider context of the Waldorf curriculum. The main lesson system is an essential constituent of the Waldorf curriculum. Most academic subjects in a Waldorf school are taught in a three- or four-week main lesson block. The main lesson occupies the first two hours of the school day. A main lesson consists of a particular three-part structure, and the main lesson book is the keystone to the Waldorf evaluative process. The Parzival main lesson is specifically taught in Class 11, and most Waldorf schools consider it as one of the most important main lessons in the high school. The interpretivist model was ideally suited to this research. The investigation was conducted as a multiple case study, and the main source of data was provided by classroom observation. This was supported by interviews and classroom artifacts. The study involved two South African Waldorf schools at which the Parzival main lesson is taught. This main lesson is presented at only three South African Waldorf schools. I teach at the remaining school, and therefore conducted my research at the other two schools. The teachers who facilitated the Parzival main lesson, as well as the Class students at the selected schools voluntarily participated in the research. My research findings indicate that the possibility exists for the teacher to exercise a certain degree of freedom and creativity within the parameters of Waldorf methodology and the Waldorf curriculum. The study also determines that teachers often find it difficult to integrate the three-part structure, as indicated by Waldorf methodology, in a single main lesson. Furthermore, my research establishes that main lesson books can indeed serve as both text and as an assessment tool. I therefore conclude and maintain in this study, with particular reference to the Parzival main lesson, that despite the prescriptive structure of the Waldorf system and Steiner pedagogy, teachers need not necessarily sacrifice their freedom and creativity within the classroom.

  • Description: In this paper, we review South African research conducted in the last 10 years on the consequences of and contributory factors in teen-aged pregnancy. We discuss research into the rates of teen-aged pregnancy, the intentionality and wantedness of pregnancy, the disruption of schooling, health issues, consequences for the children, welfare concerns, knowledge and use of contraception, timing of sexual debut, age of partner, coercive sexual relations, cultural factors and health service provision. We compare this discussion to the reviews on the same topic appearing in the South African Journal of Psychology a decade ago. We find that there are several changes in focus in the research on pregnancy amongst young women. We conclude that, in general, there has been an improvement in the breadth of data available, mostly as a result of representative national and local surveys. A better teasing out of nuances around particular issues and a grappling with theoretical issues are also evident in recent research.

  • Description: This study attempts to make a contribution to the critique of contemporary capitalism. This has been conceptualised through a Foucauldian critique of neo-liberalism, that is, Foucault’s concepts of power and governmentality have been used to criticise neo-liberalism. The study argues that neo-liberalism is a hegemonic and oppressive politico-economic social system. This has occurred in two ways; firstly, neo-liberalism came to dominate the global economy and, secondly, neo-liberalism has become the dominant politico-economic discourse. An attempt is made to expose the discourses and institutions that buttress the neo-liberal project by undertaking a Foucauldian critique. According to Foucault, knowledge shapes the social space through its ‘mechanisms’, discourses and institutions. In order to critique neo-liberalism, it is necessary to expose its power-knowledge base, which is what gives it legitimacy. By analysing and exposing neo-liberalism’s power-knowledge base, its oppression becomes clear through an observation of the material effects of neo-liberal ideology and policy. This study also evaluates to what extent Marxism is a viable alternative to neo-liberalism, in order to ascertain what Foucault adds to already existing critiques of capitalism, and neo-liberalism, in particular. It concludes by arguing that even though Marxism provides a useful framework in which to understand neo-liberal domination, its labour based social theory is somewhat outdated in our contemporary age of the information society. Therefore, it is Foucault’s concept of power-knowledge that is most pertinent in providing an effective critical theory of neo-liberalism in the age of the information society, as it focuses on the primacy of power-knowledge in matters of domination.

  • Description: The widely accepted standards of Service-Oriented Architecture (SOA) have changed the way many organisations conduct their everyday business. The significant popularity of mobile devices has seen a rapid increase in the rate of mobile technology enhancements, which have become widely used for communication, as well as conducting everyday tasks. An increased requirement in many businesses is for staff not to be tied down to the office. Consequently, mobile devices play an important role in achieving the mobility and information access that people desire. Due to the popularity and increasing use of SOA and mobile devices, Mobile Service-Oriented Architecture (Mobile SOA) has become a new industry catch-phrase. Many challenges, however, exist within the Mobile SOA environment. These issues include limitations on mobile devices, such as a reduced screen size, lack of processing power, insufficient processing memory, limited battery life, poor storage capacity, unreliable network connections, limited bandwidth available and high transfer costs. This research aimed to provide an elegant solution to the issues of a mobile device, which hinders the performance of Mobile SOA. The main objective of this research was to improve the effectiveness and efficiency of Mobile SOA. In order to achieve this goal, a framework was proposed, which supported intelligent compression of files used within a Web Service. The proposed framework provided a set of guidelines that facilitate the quick development of a system. A proof-of-concept prototype was developed, based on these guidelines and the framework design principles. The prototype provided practical evidence of the effectiveness of implementing a system based on the proposed framework. An analytical evaluation was conducted to determine the effectiveness of the prototype within the Mobile SOA environment. A performance evaluation was conducted to determine efficiency it provides. Additionally, the performance evaluation highlighted the decrease in file transfer time, as well as the significant reduction in transfer costs. The analytical and performance evaluations demonstrated that the prototype optimises the effectiveness and efficiency of Mobile SOA. The framework could, thus, be used to facilitate efficient file transfer between a Server and (Mobile) Client.

  • Description: South Africa has the largest number of people living with HIV of any nation in the world. While various conditions and circumstances have made South Africa especially susceptible to an HIV/AIDS pandemic, its leadership has not recognized the impact of the disease or found appropriate strategies to address rising rates of infection. Thabo Mbeki's presidency (1999—2008) and the appointment of Manto Tshabalala-Msimang as his health minister were disastrous in terms of the pandemic.

  • Description: A good indicator of successful farm redistribution cases has to be the continuation of viable productivity rates in their post transfer periods. Continued productivity benefits all the stakeholders that are involved in the process. Unfortunately negative productivity levels have been reported in numerous South African land redistribution transfers in recent years. A game theoretic perspective is adopted to argue that cooperation among key stakeholders, which could be enforced through long term contracts between a land buyer, sellers and new owners, would lead to higher productivity levels and other benefits. Additional benefits would, for example, include market related prices paid by a buyer.

  • Description: The ovaries of Labeo victorianus are paired organs situated in the peritoneal cavity and suspended on either side of the midline by a mesovarium. A capsule, composed of dense, regularly-arranged collagen and elastic fibres mixed with a few smooth muscle cells, enclosed the ovaries and gave off connective tissue septa, forming the ovigerous lamellae, which contained germ and follicle cells. Eight discrete stages of recrudescence were identified: oogonia, chromatin nucleolar oocytes, perinucleolar oocytes, primary yolk vesicle oocytes, secondary yolk vesicle oocytes, tertiary yolk vesicle oocytes, post-ovulatory follicles and atretic oocytes. Ovulation seemed to be synchronised with the onset of rainfall, with some deviations in the Sio River population. Gonadosomatic index variation followed a bimodal pattern, with maxima between January–February and between September–October for both populations. The same pattern was exhibited for both rainfall and water levels at the two study sites. Successful ovulation was followed by the formation of post-ovulatory follicles and Type I atresia, while failed spawning was characterised by Type II atresia. Clearance of post-ovulatory follicles was by phagocytosis and formation of melanomacrophage centres. There were variations in post-ovulatory changes between the two populations. Reproductive patterns in the Kagera River population conformed to the ‘norm’ in African labeines of the synchronisation of spawning with rainfall. Slight deviations from this pattern were, however, observed in the Sio River population where spawning occurred prior to the onset of rainfall.

  • Description: While career development is viewed as a lifelong process, there are numerous limitations regarding existing career theories and research pertaining to the adolescent population. Further, insufficient longitudinal research represents one of the major obstacles for a more holistic understanding of career development across the lifespan. Thus, the present longitudinal project of which the current study forms a part was initiated to address the lack of research and theory concerning adolescent career development. The larger longitudinal project intended to make information available regarding the occupational aspirations and perceptions of a sample of South African children and adolescents, from early childhood into their adolescent years. The current study investigates the occupational aspiration development of 15 to 16 year old South African adolescents. It is argued that the South African knowledge base on career development behaviour still requires extensive development, especially with regards to adolescent career development. The current longitudinal study aimed to explore and describe possible developments and changes over a two year period in the interest typology, occupational status level and occupational gender stereotypes of the 43 adolescents. Additionally, the study aimed to explore and describe the adolescents' reflections on their own occupational aspiration development. The findings of this study will provide necessary baseline information on the development of South African adolescents' occupational aspirations and will offer valuable recommendations for the future development of adolescent career education programmes. Adolescent and career development theories were used to provide a context for the current study. Semi-structured interviews and biographical questionnaires were utilized to record verbal data which was transposed into nominal data for analysis. Thus, the current study was quantitative in nature. The semi-structured interview comprised four general aspects that included: the adolescents' occupational aspirations, the number of occupations they knew about, how much they knew about the expressed occupations, and the extent to which they held gender stereotypes concerning fourteen different occupations. The data gained was coded according to Holland's (1985) classification system of interest typologies. Also, the adolescents' occupational aspirations were coded according to their status levels. The coded data was subsequently analysed using both descriptive statistics in the form of frequency counts and percentages as well as inferential statistics in the form of chi-square analysis. Content analysis was also conducted on the adolescents' reflections on their own career development as a means to extract themes. The results indicated that adolescence was an important phase of career development and the findings supported adolescent and career development theories. The results of the study also indicated that the majority of adolescents aspired to Investigative type occupations across both years of the study and most adolescents consistently aspired to high status occupations. In addition, adolescents do not appear to gender stereotype in terms of occupations. Lastly, it was found that most adolescents could reflect on their career development, predominantly attributing changes in their occupational aspirations to changes in their interests. The present study has made available important information regarding the occupational aspiration development of a group of South African adolescents, which can be utilized in further research and as a foundation on which to develop career education programmes.

  • Description: Society’s reliance on Information Technology (IT) has increased tremendously in the last few decades. Unfortunately, the growth of the IT sector has occurred at the expense of the environment. The adverse environmental impact of IT operations is partly due to the production and disposal of IT equipment, which can result in harmful pollution and toxic materials being released into the environment. Furthermore, IT equipment consumes large amounts of electricity, and this results in significant amounts of carbon dioxide (CO2) being released into the atmosphere. Since CO2 is classified as a greenhouse gas, it contributes to the phenomenon of climate change. Organisations are socially and ethically required to minimise the environmental impact of their IT operations. However, in addition to fulfilling their responsibility towards environmental sustainability, organisations can gain a competitive advantage through adopting green IT practices. In order to reap the benefits of green IT and to fulfil their social and ethical responsibilities, organisations need to formulate and implement a comprehensive green IT strategy. When formulating strategic decisions, the use of a clear decision process enhances the effectiveness of such decisions. As a result, top IT management require a model or framework which could guide their thinking and allow for a clear decision process when formulating green IT strategy. However, after an extensive search of the literature had been conducted, a research gap was identified for the definition of a model which deals specifically with the formulation and execution of green IT strategy. As a result, this treatise sets out to answer the question of what organisations should consider when formulating and implementing green IT strategy. To answer the research question, the treatise defines a model for green IT strategy. The model was defined by conducting a content analysis of the literature on green IT. The content-analysis ABSTRACT iii research technique was utilised to identify the underlying concepts within the literature related to green IT strategy formulation and execution. The resulting model indicates that green IT strategy formulation requires holistic thinking, since several forces affect green IT strategy. As a result, these forces should be considered when a green IT strategy is to be formulated. However, even if a strategy is formulated by considering all the forces at play, it is of little use if it is not implemented effectively. The model indicates that green IT strategy should be implemented though a series of practices. These practices are not limited to IT practices alone, but include, in addition, several business practices. This indicates that green IT adoption extends far beyond the mere implementation of green technology.

  • Description: The Information and Communications Technology (ICT) skills shortage is of national and international concern. Modern business practices require the implementation of new technologies supported by a workforce with current and diversified ICT skill-sets. Acquiring suitable ICT skills has become a difficult task and employers are seeing government intervention at all levels. The school system in South Africa is under increased pressure and is faced with continuously declining matriculation pass rates, specifically in subjects such as science and mathematics. Schools are experiencing a decline in the number of scholars (learners) enrolling for the Information Technology (IT) school curriculum. The IT curriculum at school level is being criticised; under-prepared teachers are blamed and lack of suitable facilities highlighted. Surveys conducted amongst grade 9 and grade 12 scholars in the Eastern Cape have shown that scholars are not considering careers in ICT. Teachers, career/guidance counsellors and parents contribute to scholars' career decisions and are not encouraging scholars to pursue careers in ICT. Tertiary institutions in South Africa and internationally, are experiencing a decline in student enrolments and in pass and throughput rates. Industry is holding tertiary institutions responsible for not providing the “correct” ICT graduate skill-sets and passing an insufficient number of quality ICT graduates desperately required by industry. The accreditation of computing degree programs, such as Computer Science (CS), Information Systems (IS) and Information Technology (IT), collectively referred to as CIT, offered by tertiary institutions is becoming an international requirement. The ICT industry is constantly changing and new job requirements and new career opportunities are frequently introduced. Graduates entering the ICT industry should have acquired knowledge about ICT career tracks in order to specialise and choose a suitable career path. Tertiary CIT degree programs should further be linked to specific career tracks and provide a multi-disciplined education to graduates. ii ICT graduates working in industry utilise skills obtained in under-graduate and post-graduate CIT degree programs. The ICT graduates have also obtained valuable skills working in industry, including business skills and soft skills. ICT skill surveys have identified the graduate skills gap, indicating ICT skills industry requires from graduates completing tertiary level qualifications. ICT graduates working in industry, for example indicated that programming in some cases is over-emphasised at school and tertiary level and that soft skills are ignored by tertiary institutions. An ICT Graduate Skills Classifications Framework is developed to address the graduate ICT skills gap and highlight important business skills, soft skills, technical skills and programming skills required by industry. In this thesis, an Industry ICT Value Chain Model is further developed that suggests a holistic approach to the problems experienced at all levels of ICT skills development, including government, industry, tertiary education institutions and at school level. Results from a number of research surveys conducted along the proposed Industry ICT Skills Value Chain Model indicated that problems exist at all stages in the value chain and that the problems can only be addressed involving government, industry and tertiary institutions collectively. A number of interventions is required and the support from industry is essential in achieving overall success in addressing the ICT skills shortage in South Africa. A proposed Industry ICT Skills Value Chain Model that can be utilised to address the ICT skills shortage in South Africa is presented.
