- Description: Climate change has become a discussion topic of exponentially increasing urgency and importance amoung world leaders of all disciplines. These changes are brought about by the emission of so-called Greenhouse gases from various human activities. The primary cause of CO2 emissions is the burning of the Earth’s supply of nonrenewable natural fossil fuels like coal, oil and natural gas. The world first agreed on the prevention of “dangerous” climatic changes at the Earth Summit in 1992. The Kyoto Protocol of 1997 was the first step toward protection of the atmosphere and prescribes restrictions on emission pollutants. Since then the vehicle gas emissions are being controlled by means of different gas emissions norms, like the European Union Norm in Europe. The automotive manufacturers and suppliers are collectively working on reducing overall vehicle emissions. They are focusing on several different emission limiting possibilities, for example improved engine design, special fuel development and exhaust gas treatment systems. The exhaust gas treatment process requires continuous controlling and management of the exhaust gas emissions while driving a vehicle. Certain factors such as high emission temperatures have a negative influence on the life span of these systems. Their functionality and durability is also known to be reduced by the presence of chemical poisoning species like sulphur, phosphorus, zinc and calcium. The chemical poisoning species are produced during combustion of fuel and engine oil. They are therefore contained in the exhaust emissions and can poison the catalyst when passing over it. Phosphorous poisoning is particularly problematic and should be reduced considerably. This study involves the investigation of the phosphorous poisoning process and aims to provide clarity regarding the influences of different fuel and oil compositions on the severity of the process. Engine oil and biodiesel are two major sources of phosphorous poisoning. The phosphorus contained in biodiesel fuel is a natural component and can be minimized during the refining procedure. In contrast to others studies, the biodiesel fuel used during this project was SME (Soya Methyl Ester) with a 20% biodiesel content. This choice of fuel was made because of the increasingly important role that this type of biodiesel is playing in the European market and the future tendency to increase the percentage of biodiesel in the mixture with standard diesel fuel. The phosphorus contained in engine oil is a necessary additive to retain the antioxidant and anti-wear properties of the oil. This study examined the poisoning influences from the most commonly used phosphorus containing oil additive, Zinc Dithiophosphates (ZDDP), as well as a Zn-free, phosphorus containing anti-wear oil additive. This formulation provides information about the phosphorus poisoning process as caused by the engine oil in the absence of Zn in the oil additives. The results show how the phosphorus content in biodiesel fuel affects the functionality of the exhaust gas treatment systems and the importance of reducing the permitted content of phosphorus contained in the fuel. Reducing the phosphorus content in the fuel will conserve the functionality of the exhaust gas treatment systems during their operational life and thereby protect the environmental from emission pollutants. It also provides insight into the differences in the poisoning processes when the phosphorus deposited on the catalyst comes from biodiesel fuel and when it comes from the engine oil. Finally the results also illustrate the influence of different phosphorous forms contained in engine oil additives on the catalyst poisoning process. This information could be used for the development of new oil additive formulations.

- Description: This dissertation is a systematic study of the 22kV Nelson Mandela Bay Municipality (NMBM) electricity power distribution network reliability evaluation and improvements to be applied. Reliability evaluation of electric power systems has traditionally been an integral part of planning and operation. Changes in the electricity utility, coupled with aging electrical apparatus, create a need for more realistic techniques for power system reliability modelling. This work presents a reliability evaluation technique that combines set literature and evaluation criteria. In analysing system reliability, this research takes into account the reasons for many outages and voltage dips and seeks to find mitigating approaches that are financially justified. The study analyses the power system in terms of the methodology developed, using power system reliability techniques, power quality evaluation, protection analyses and evaluating the network against maintenance interventions and programs, manpower availability and weather conditions contributing to the outages. In evaluating the power system various techniques are used to determine if the power network operates within the NRS standards, namely, reliability calculations, testing of protection equipment, interrogation of power quality instruments and modeling the network on Digsilent. This study will look at all the important factors influencing power system reliability, analysing the network in terms of the methodology and recommend improvements.

- Description: In most research, appropriate collections of data play a significant role in aiding decision-making processes. This is more critical if the data is being accessed across organisational barriers. Further, for the data to be mined and analysed efficiently, to aid decision-making processes, it must be harnessed in a suitably-structured fashion. There is, for example, a need to perform diverse data analyses and interpretation of structured (non-personal) HIV/AIDS patient-data from various quarters in South Africa. Although this data does exist, to some extent, it is autonomously owned and stored in disparate data storages, and not readily available to all interested parties. In order to put this data to meaningful use, it is imperative to integrate and store this data in a manner in which it can be better utilized by all those involved in the ontological field. This implies integration of (and hence, interoperability), and appropriate accessibility to, the information systems of the autonomous organizations providing data and data-processing. This is a typical problem-scenario for a Virtual Inter-Organisational Information System (VIOIS), proposed in this study. The VIOIS envisaged is a hypothetical, secure, Wireless Grid-enabled Data Warehouse (WGDW) that enables IOIS interaction, such as the storage and processing of HIV/AIDS patient-data to be utilized for HIV/AIDS-specific research. The proposed WDGW offers a methodical approach for arriving at such a collaborative (HIV/AIDS research) integrated system. The proposed WDGW is virtual community that consists mainly of data-providers, service-providers and information-consumers. The WGDW-basis resulted from systematic literaturesurvey that covered a variety of technologies and standards that support datastorage, data-management, computation and connectivity between virtual community members in Grid computing contexts. A Grid computing paradigm is proposed for data-storage, data management and computation in the WGDW. Informational or analytical processing will be enabled through data warehousing while connectivity will be attained wirelessly (for addressing the paucity of connectivity infrastructure in rural parts of developing countries, like South Africa).

- Description: The main problem of this study was to assess the communication strategies used by GIRSS to achieve organisational goals. To address this problem, a theoretical study was undertaken to identify the communication strategies used in organisations. The theoretical guidelines for effective communication were integrated into a communication model, which consisted of the following components: · The establishment of organisational communication structures; · The selection of appropriate communication media; IV · The management of communication barriers; and · Addressing the challenges in organisational communication. Based on the model, a survey questionnaire was developed to assess the extent to which GIRSS made use of these strategies. The questionnaire was administered to both managers and non-managers in the organisation. Due to the distance between South Africa and China, the questionnaire was administered via e-mail. The empirical results revealed that some of the theoretical guidelines were followed, but there was room for improvement in terms of communication strategies used at GIRSS. Specifically it was found that many barriers existed as a result of status and other differences, which influenced communication in the organisation. Communication in organisations is very important as it contributes to goal attainment, satisfaction, cooperation and problem-solving. Communication is a skill that can be learned, and managers as well as employees should consider the results of the study to initiate changes to the communication strategies used in the organization.

- Description: The South African sheep industry has experienced an increase in the price of meat and wool over the past several years. This has led to an interest in intensification of sheep production off planted pastures. Due to this phenomenon an economic viability study was done on the intensification of sheep production on cultivated pastures under irrigation. When intensifying sheep production, certain management practices need to be incorporated in order to enhance the output obtained per hectare and to overcome the higher input cost of production. Management practices that could be included are creep feeding, accelerated breeding and feedlotting of lambs after weaning. In order to determine the economic viability of such a system, certain production parameters need to be obtained for producing sheep intensively from cultivated pastures. Three studies were conducted to obtain the required production parameters; these were then followed by an economic evaluation incorporating the parameters obtained from the studies. All the studies were conducted at Kromme Rhee and Langgewens, two research farms of the Department of Agriculture in the Western Cape.

- Description: The world has entered the information age. How the information is used within an organization will determine success or failure of the organisation. This study aims to provide a model, that once implemented, will provide the required protection for the information assets. The model is based on ISO 27002, an international security standard. The primary objective is to build a model that will provide a holistic security system specifically for a South African Micro Finance Company (MFC). The secondary objectives focuses on successful implementation of such a model, the uniqueness of the MFC that should be taken into account, and the maintenance of the model once implemented to ensure ongoing relevance. A questionnaire conducted at the MFC provided insight into the perceived understanding of information security. The questionnaire results were used to ensure the model solution addressed current information security shortcomings within the MFC. This study found that the information security controls in ISO 27002 should be applicable to any industry. The uniqueness for the MFC is not in the security controls, but rather in the regulations and laws applicable to it.

- Description: South African businesses are facing unforeseen opportunities and threats following the country’s remarkable political transformation that culminated in its first non-racial, democratic elections in April 1994 (Krüger, 1997: 138). The objective of this paper was to understand what core competences a South African motor vehicle assembler requires to survive this era of declining protectionism and increasing competition. It is argued in this paper that organisations that want to compete with the best in the world market needs to adopt lean manufacturing principles. This paper is concerned with the core competences of an organisation and how an organisation identifies and utilises these in order to become a lean enterprise. The qualitative research method was identified as the most appropriate for the study. Two methods of data collection were used i.e. interviews with senior and middle management and a detailed literary study on the subject. The senior management interviews were aimed at identifying what they perceived to be the core competences a motor vehicle assembler requires in order to be a world-class lean manufacturing enterprise. The literary study was the base for the understanding of core competence and lean manufacturing. Finally, a second round of interviews with middle management was conducted to obtain clarity on the perceived role of middle management in the selected organisation’s quest to be a lean manufacturing concern. This paper concludes that if an organisation wants to survive it needs to identify and assess its core competences. These competences need to be developed or discarded in the organisation’s aims to be a lean manufacturing enterprise by eliminating all forms of non-value added activity. The programmes or projects that the selected organisation embarked on were primarily driven from the top down, placing middle management in the centre with the resistance coming from the lower levels in the organisation. Middle management should be given the necessary tools to overcome the resistance and assist the company to make smooth transitions.

- Description: This study focuses on the effective implementation of C2005 by the Grade 7 teachers in the Motherwell area. For teachers to meet the demands of the new curriculum, in-service training is needed to develop them to be competent in all the aspects required for the use of the OBE approach. The main research question is: How have Grade 7 teachers in Motherwell implemented C2005 in their classrooms? Questionnaires and interviews were used as tools to collect the data. The data was collected from five selected primary schools in the Motherwell area. The teachers’ responses obtained from questionnaires and interviews were analyzed both statistically (using tables) and descriptively (telling teachers’ stories). Responses determined the competence of teachers in four areas, namely, teaching methods, content, classroom organization and assessment of learners. An account of inservice training courses attended by teachers is provided. These courses revealed the problems encountered by teachers during the implementation process and the subsequent assisstance they received. The data provided in this study is in line with the research done by the Review Committee (Chisholm, 2000) in the Eastern Cape. Recommendations of the Review Committee gave rise to the establishment of the Revised National Curriculum Statement (RNCS). The responses from this study confirmed the need for retraining of teachers to develop their competences. This study urges the Department of Education to focus on establishing methods of training that will develop teachers in their teaching experience. The SMTs should also be able to assist teachers with the problems they encounter in their schools. Teachers should be able to take responsibility for their learners’ competence and take ownership of changes in their schools. The financial assistance of the National Research Foundation towards this research is hereby acknowledged. Opinions expressed in this thesis and conclusions arrived at, are those of the author and not necessarily to be attributed to the National Research Foundation

- Description: Effective leadership is one of the most important factors that influence the performance of an organisation. Effective leadership together with supervision are similar in terms of their influence of others towards achieving the goals of the organisation. Therefore, effective leadership and supervision are principal activities through which organisational goals and objectives are achieved. The main objectives of this study are firstly to evaluate the leadership effectiveness of production supervisors at Lennon and Intramed. Secondly, to suggest recommendations to management to improve or eliminate shortcomings in the leadership effectiveness of the production supervisors at Lennon and Intramed. In this way, a contribution to the overall leadership effectiveness of the production supervisors at Lennon and Intramed is achieved. In order to achieve the said objectives, the following methodology was employed: Firstly, guidelines for effective leadership were identified by means of evaluating existing literature and theory. This was achieved by critically examining existing leadership theories and models. The major contributions, disadvantages, and advantages of each of these theories and models were evaluated which resulted in the list of guidelines for effective leadership. Secondly, the pharmaceutical industry and the theory surrounding supervision were critically examined and discussed. Attention was given to the pharmaceutical industry in South Africa, with special reference to Lennon and Intramed. The theory of supervision was examined with special focus on the skills, functions, power, and responsibilities of the supervisor. Thirdly, a postal questionnaire was used to gather the required empirical information. The response obtained from the questionnaire was critically evaluated against the guidelines for effective leadership and effective supervision, and the results were graphically represented in a company leadership profile. Lennon and Intramed were evaluated separately, and the major differences and similarities between the two organisations were critically evaluated. Lastly, the main findings and recommendations were formulated in order to remedy the shortcomings that were identified. The following recommendations may lead to more effective leadership among production supervisors at Lennon and Intramed: It is necessary that this study be made available to the supervisors at Lennon and Intramed, as it will give them insight into the theory of leadership and what effective leadership is about. It will furthermore give the supervisors an insight into the way that their subordinates view their leadership behaviour and effectiveness. It is further recommended that the information from this study be made available through sensitisation sessions where the necessary information is presented to a group or individual supervisors. Leadership training and development is required as it can make a meaningful contribution to equip supervisors with the necessary leadership skills to practise effective leadership. This leadership training and development can be done by means of short courses presented by a formal training institution, or by a suitably qualified in-house presenter. The last recommendation to leadership effectiveness involves the implementation of a performance management system and incentive scheme to further motivate and drive the supervisor’s leadership behaviour towards effective leadership.

- Description: The primary goal of this study was to evaluate the role of cost management control systems (CMCS) on organisational performance of public enterprises in Namibia, using Namibia Airports Company (NAC) as a case study organisation. NAC uses the activity based costing (ABC) management control system and is still making losses, the auditor General have recommended that there is a need to evaluate the CMCS used by the NAC and their expenditure. In pursuing the primary objective of the study, four secondary objectives were therefore developed. The first objective was concerned with evaluating the purpose of the CMCSs in organisational decision making process. The second objective was concerned with analysing the effect of CMCSs on organisational performance in public enterprises. This was also achieved through a comprehensive review of literature. The third objective dealt with the design of a suitable methodology. The last objective was concerned with conclusions and recommendations of the study. The study followed a quantitative research methodology and a total of 100 questionnaires were self-administered to the respondents. Sixty-five questionnaires were returned with usable responses and were captured for analysis. Statistical analysis was applied in order to meet the requirements of research methodology as well as record and analyse the research findings. The study used descriptive statistics, reliability statistics, factor analysis and one way variance analysis (ANOVAs). Factor analysis was performed on the elements used to measure the impacts of CMCSs on the organisational performance of the Namibia Airports Company. Four key impacts of CMCSs were identified in this study. ANOVAs were employed as a way of determining significant differences between groups with regard to the factors that were identified. The finding of the study revealed that, the level of employee involvement in cost management activities is relatively weak at Namibia Airports Company despite a higher frequency of using the CMCSs. There is a significant effect on financial performance of the organisation as a result of employing CMCSs. The significant impacts of CMCSs on the organisational performance of the Namibia Airports Company include opportunities for improving financial performance management, efficiency in service delivery, and strategic decisions.

- Description: A background of serious disparities in past welfare policies, legislation and programmes, necessitated the need for a far-reaching new social welfare policy in South Africa. The adoption of the White Paper for Social Welfare by Parliament in February 1997, set the path for the new social developmental approach to social welfare, dealing with key substantive issues in addressing the restructuring of social welfare services, programmes and social security. The Eastern Cape Province is one of the poorer provinces in South Africa. Negative radio and print media reports on social welfare in the province in the past three years has made it clear that serious problems and disparities face the provincial department. Several of these media reports highlighted issues relating to poor service delivery and unacceptable conditions of underdevelopment and poverty still prevailing in the province. The Eastern Cape Welfare Department has been plagued by fraud and corruption, and in a report of the Eastern Cape legislature’s standing committee on welfare in 2001, it was found that fraudulent activities, corruption and misconduct by government officials are still prevalent in the welfare department. The objective of this research was to assess whether the Eastern Cape Department of Social Development (Welfare) is implementing this new social developmental approach to social welfare, as set out in the 1997 White Paper for Social Welfare.

- Description: The evaluation of the potential to use Ultra Performance Liquid Chromatography (UPLC) for the simultaneous quantification of all the actives in a multi-active tablet is described in this work. Part of the evaluation was to ensure that the necessary regulatory requirements were adhered to by ascertaining that an analytical method is suitable for a specific purpose through analytical method validation for the specific multi-active tablet. The UPLC method was also tested for the analysis of similar products, namely tablet formulations that contain similar active ingredients in the same proportions but with an additional active ingredient. A method for the simultaneous determination of paracetamol, caffeine and codeine phosphate was developed using UPLC technology. The UPLC developed method was more efficient than the existing in-house HPLC method. The UPLC method was then validated in accordance to ICH and USP guidelines. The application of this UPLC method for the analysis of similar products containing paracetamol, caffeine, codeine phosphate and one extra active ingredient was very challenging. The low concentration of the additional component, differences in sample matrix and differences in formulations added to the challenges. The direct application for the analysis of products Y and Z was not successful; however the method could be used as a platform for further research. A cost comparison between the UPLC and HPLC methods showed the UPLC method to be more cost effective. Thus, while maintenance costs are higher for the UPLC instrument, column costs are comparable to HPLC columns, but solvent and waste disposal charges decrease considerably due to lower solvent use. The reduction in instrument time dramatically improves the cost effectiveness of UPLC over HPLC due to a concurrent reduction in analyst time requirement. The results of this study show that the analytical costs associated with the analysis of multi-active drugs using HPLC procedures can be reduced substantially by the CONFIDENTIAL INTELLECTUAL PROPERTY OF ASPEN PHARMACARE implementation of UPLC technology. The hypothesis that the enhanced chromatographic power of UPLC can be leveraged to provide faster analysis times hence increased product throughput rates, and lower operating costs for the analysis of multi-active drugs was accepted. These advantages were achieved whilst meeting all regulatory requirements for analytical methods as required by regulatory bodies.

- Description: The purpose of this study was to develop a process model in order to meet outcomes of graduate training programmes, with specific relevance to Volkswagen of South Africa. To do this, VWSA’s Graduate Training Programme was assessed in terms of the approach currently used by VWSA to recruit, select and train graduate trainees. A literature study was conducted to reveal strategies for effectively training new recruits and the development of leadership competencies. Based on this study a model was developed to facilitate the graduate training programme process to achieve programme objectives. The study aimed at making a contribution to graduate training programmes by identifying key leadership competencies, as well as the training interventions which lead to the development of these competencies. It was found that the technical skills that the trainees acquire at their tertiary educational institutions are not sufficient in today’s workplace, thereby necessitating closer working relationships between these institutions and businesses so that needs can be shared, as well as more comprehensive training programmes being provided. The research methodology comprised the following steps: An analysis was made of VWSA’s current processes regarding recruitment, selection and training of their graduate trainees. iv An assessment of leadership competencies in terms of knowledge, skills and attitudes that contribute to successful performance was undertaken. Training interventions as a process was studied. An analysis was made as to what extent the existing training interventions for VWSA’s graduate programme achieve the desired programme outcomes by means of a research questionnaire circulated to mentors/coaches and graduate trainees within the organisation. A model was developed to serve as a holistic framework for the recruitment, selection and training of graduate trainees for all motor and related industries undertaking graduate training programmes. The above was achieved through a practical study and a literature study, making use of questionnaires, as well as relevant published, unpublished and electronic texts and studies. Conclusions were drawn and recommendations were made based on data established through theoretical research and data obtained from the questionnaires.

- Description: The diversity of wildlife resources and the highly-developed trophy hunting and game ranching industry make South Africa a sought-after destination for travelling hunters. Significant economic, social and ecological benefits result from the annual visits of 16 000 hunters. These benefits, in turn, accelerate industry competition. To maintain or increase the clientele base, hunting providers should continue to manage and improve their clients’ safari experiences. This research investigated visiting hunters’ South African safari experiences by measuring their perceptions of service quality, satisfaction and behavioural intention. The results of the research could assist hunting providers in identifying areas where service expectations are not met and understanding the impact of service quality and satisfaction on clients’ loyalty. The literature study contextualised the South African trophy hunting industry within the tourism environment, the realms of wildlife tourism, and the characteristics of hunting tourism. An overview of tourism services, service quality, customer satisfaction, and behavioural intention was also provided. The resulting conceptual model hypothesised relationships among the safari experience variables (service quality, satisfaction and behavioural intention). ii The empirical data were collected by means of a mail survey, using a self-administered questionnaire distributed to 2 000 foreign hunters who had participated in a South African hunting safari at least once between 2003 and 2007. Two hundred and thirty six completed questionnaires were returned, giving a response rate of 13.2%. The majority of the hunters were male, aged between 40 and 60 years, and from the United States of America and Europe. Hunters perceived the level of service quality delivery by hunting providers to be relatively high and were generally satisfied with their South African safaris. As a result, they were willing to return for another hunting experience and were very likely to speak positively about their experiences. By performing exploratory and confirmatory factor analyses, a three-factor (augmented services, core services and supporting services) service quality construct was identified and confirmed. Multiple regression analyses found that core services was the strongest predictor of overall satisfaction; overall satisfaction was significantly related to revisit intention; and revisit intention significantly predicted word-of-mouth intention. An empirical model was accordingly constructed to replace the original conceptual model. iii It is recommended that South African hunting safari providers should: {u10007A} use the suggested measuring instrument to monitor their performance of service quality delivery on a regular basis; {u10007A} train their employees to ensure that they are knowledgeable and well prepared for field guidance and to promote ethical hunting practices; {u10007A} ensure an abundance of game and a wilderness atmosphere in the hunting area; {u10007A} conduct focus group studies to further understand the factors that shape clients’ perceptions of the safari experience; and {u10007A} invest in developing long-term relationships with existing clients.

- Description: The diversity of wildlife resources and the highly-developed trophy hunting and game ranching industry make South Africa a sought-after destination for travelling hunters.

An examination of the visual representation of young white Afrikaner women
- Authors: Jordan, Nicole

- Description: The purpose of this qualitative research study is to comment on the visual representation of women between the ages of twenty and thirty within white contemporary Afrikaans culture. This will be achieved through an analysis of stereotypes evident in Afrikaner culture. Examples of this include but are not limited to the text and visuals in the Goeie Maniere en Etiket (1981) book by Emsie Schoeman and dated Afrikaans magazine issues by Huisgenoot (Issue XLII, 2 June 1961) and Sarie Marais (Issue 17/19, 30 March 1966). Interviews were conducted with five white young Afrikaner women using a collaborative approach, to gain a better understanding of the influences that cultural and visual stereotypes have on an individual. The research aims to comment on how the emerging post-apartheid generation of young Afrikaner women are responding to the cultural expectations and engaging with their Afrikaner identity in the way they choose to represent themselves through tableau portrait photography. The study is based on a practice-based research method, which encompasses two components: a written output and a practical output. These function as a unity, where the written component guides the development of the practical body of work. The written document provides the foundation and framework in which the practical work functions, creating a conceptual framework that guides the process of collaboration between the visual artist and subject to construct a contemporary visual representation that focuses on how young Afrikaner women react to traditional cultural roles and develop an understanding of self. The study makes use of Gillian Rose’s visual analysis framework as a critical analysis tool to determine the visual representation that emerges from the collaboration between the visual artist and the subject. Ultimately, the aim of this research is to facilitate the potential for the subject to critically engage with visual identity by collaborating with the visual artist. This research presents a unique approach to communicate an evolving post-apartheid identity and has contributed to an understanding of the feminine identity construction of the emerging Afrikaner generation in a democratic South Africa.

An exploration of absence and presence through the mediums of bronze, glass and resin figurative sculpture, within a narrative of memory

- Description: This research study was based upon three critical components. These include absence and presence, memory and the female nude. The problem statement aimed to determine how compositionally sound pairings and groupings of bronze, glass and resin figurative sculptures may be manipulated to create visual equilibrium in a work and communicate an inherent conceptual element. This necessitated the following research question which explored what the role of memory and the imago is within dualistic representations of the absent and present, as represented in the mediums of bronze, glass and resin. The creative and research processes culminate in the body of artwork, entitled Absence and Presence: in Search of Memory and the Imago, which is presented as a narrative installation and exhibition of sculptural work. This body of work was driven by the creation of a signifier and allegory for an absent presence or present absence which will always evoke the contemplation of this interplay between these two terms and the ways in which they define and become one another within the narrative of personal memory. Personal memories will always collide with the present and bring with them the memories of absence, but encourage the subject to make tangible this absence in order to confront it and in doing so, realise that it cannot be addressed separately from the presence which defines it
