- Description: The research problem addressed in this study was to identify what management skills do middle managers require to manage the organisational units effectively. To achieve this objective a theoretical model of management skills required by middle managers to effectively manage a public hospital was developed, using relevant literature in which management skills are identified. The theoretical model consisted of the following categories of management skills whose correct application can promote managerial effectiveness in managing organisational units: General management skills; Technical skills; Human skills; Leadership skills; Financial management skills; Computer skills. Each category of the management skills was broken down into elements that were then analysed using literature identified during the literature study. The model was then used to develop a questionnaire to assess the degree to which managers responsible for running the clinical, nursing and paramedical departments of a public hospital in the Eastern Cape rate the elements in terms of importance. The empirical results obtained indicate that a wide variety of skills are regarded by middle managers as important to performance of their managerial roles. This resulted in the theoretical model being confirmed and the identified management skills being accepted as management skills required by middle managers to effectively manage a public hospital in the Eastern Cape.

- Description: The research problem addressed in this study is to determine what affect current labour legislation has on small, medium and micro-enterprises (SMME’s), in particular with regard to the procuring of Government contracts. To achieve this objective a literature study was undertaken to ascertain what knowledgeable people believed was the affects of labour legislation on SMME’s. The literature study included all relevant labour legislation promulgated by the Government since 1994 The literature study was then used to develop a questionnaire to test the degree to which SMME’s, operating in the Municipal areas of East London and King Williams Town, abided by the relevant labour legislation. The empirical results, in general, indicated a strong adherence to labour legislation. Those organisations that had not strictly adhered to labour legislation were, in most instances, not successful in securing contracts offered by Government or parastatals. The results indicated that all the role-players, namely businesses, trade unions and knowledgeable people have valid arguments both for and against labour legislation. Each group, is however, still concerned and suspicious that in one way or another, they will be placed at a disadvantage with respect to the others positions, and this places a serious strain on the South African economy.

- Description: The Motor Industry is set in a highly competitive and dynamic global arena constantly shaped by both external and internal forces. From an organisations point of view many of the external or macro forces are largely uncontrollable. Against this backdrop, players in the South African Motor Industry need to find new methods of differentiating themselves from competitors – One manner of performing this strategy is for Motor Dealerships to understand, meet or exceed customer requirements. In this research, the literature survey revealed the concepts of Total Quality Management (TQM) and fail-safing, the meaning of superior customer service and the importance of customer loyalty and retention. Customer service excellence levels of three Williams Hunt dealerships in the Port Elizabeth – Uitenhage metropole were measured by utilizing the SERVQUAL instrument for calibrating service quality. Customer expectations and perceptions were determined by means of the empirical study which yielded a service quality “gap.” From analysis of this gap and related findings, suggested improvements were suggested as a guideline for dealerships to utilise with the aim of improving customer service levels.

- Description: In this research customer service excellence in First National Bank in the Port Elizabeth metropole was investigated. From the industry and competitor analysis it can be concluded that banking is a highly competitive industry that is undergoing constant change because of fierce competition. The literature survey was aimed at placing the concept of service quality, excellence and customer loyalty which lead to customer retention into perspective. The concept of total quality management outlining the specific requirements of how the concept can be utilised and how a service quality programme can be implemented was discussed. The purpose of the empirical study was to test customers’ perceptions of service provided by First National Bank and to contribute with useful information to the bank studied. From these findings improvements and recommendations were suggested as a guideline for any bank to follow to improve customer service levels. The empirical study results were satisfactory and informative. The meaningful positive responses that were identified can be utilised as competitive marketing strategies by FNB. The meaningful negative concerns the bank should consider improving upon and attention should be given to the language and SBU differences outlined.

- Description: In this research paper, the constructive management of political behaviour in organisations was investigated. A general overview of relevant aspects which specifically relate to the constructive management of political behaviour in the automotive industry was presented. The literature study included a discussion of the nature of political behaviour and guidelines for the management of political behaviour in organisations. The research methodology consisted of three phases: Phase 1: A literature study to determine guidelines to manage political behaviour in organisations constructively. Phase 2: An empirical study to determine the effectiveness of these guidelines in practice by means of a survey amongst role players in the automotive industry in South Africa. Phase 3: The findings from the literature study and empirical study were integrated into guidelines of how managers can manage political behaviour constructively. The study identified nine main strategies for managing political behaviour. They are: Open communication. Communication must be open to keep all parties informed and to prevent distrust. Reduction of uncertainty. This involves preventing employees being unsure of what the future holds. Awareness. The aim of awareness is for managers to be sensitive to and aware of situations that could elicit political behaviours. Furthermore, they must recognize political behaviour for what it is. Setting an example. Managers must set an exemplary example and not engage in political behaviour. An understanding of the reason/motivation for the formation of informal (political) groups or cliques. Having established the reason why political groups form will enable a manager to manage them more effectively. Confront political game players. Managers must address all forms of possible political behaviour in a serious manner. Understanding the organisation’s strategy, goals and action plans. All employees need to know exactly what direction the organization is moving in and what is in it for them. It is management’s task to ensure this open and clear communication, to prevent fears and political behaviour. Tie resource allocation and rewards to strategy. This can be achieved by ensuring that the criteria for the allocation of rewards is straight forward and understood by all. Reward systems must, furthermore, be directly linked to performance. There should also be transparency in decision-making. Isolate resource acquisition from internal operations. It is necessary to clearly specify the conditions and ground rules for the acquisition of resources to ensure that the process is transparent. The conclusion reached is that political behaviour in organizations can be managed constructively to build win-win relationships.

- Description: Eskom is experiencing problems in the field of protection maintenance and in-service breakdowns which negatively influence the quality of electrical supply to the consumer, an integral component of the utility business. These facts initiated the research into the further development of a generic relay to be implemented as a strategic spare for the replacement of several schemes operating within Eskom’s southern region. These include the electromechanical, solid state and numerical distance protection relay and scheme failures on the 132 / 66 kV feeder network. Hence, the primary objective of the research is to develop, test and configure the strategic spare in terms of software and peripheral hardware for the input and output terminal connections, generic equations and settings for the purpose of the scheme replacements. The various schemes are assessed for stepped distance and permissive intertripping for three or single pole operation. This is done in conjunction with the internal and external circuit diagrams in order to understand the detailed operation of the scheme and to ensure the effective implementation of the strategic spare. The generic relay is configured for the emergency replacement of the various schemes during in-service breakdowns. This constitutes a temporary installation and therefore the downtime in essence, of all the distance protection schemes that require replacement, is limited to a minimum. This dissertation therefore explores the implementation of the strategic spare.

- Description: This study is a qualitative investigation into the areas of corporate social investment and public relations. The study examines the significance of corporate social investment within the field of public relations with specific reference to selected KwaZulu Natal corporations. The study looks at the corporate social investment and public relations departments of five corporations in the KwaZulu Natal region. The corporations that were interviewed were selected based on their location, and the number of years of experience in the field. The five companies, namely, The South African Sugar Association, NBS Boland Bank, Hillside Aluminium (Alusaf), McCarthy Retail and Richards Bay Minerals received immense coverage on their corporate social investment initiatives, in the Mail and Guardian’s April 1998 issue, ‘Investing in the future, special focus on social investment.’ The report presents an in-depth literature review, which examines the history of both corporate social investment and public relations. It thereafter examines the current practices of public relations and corporate social investment from a South African perspective. The prevalent approach to corporate social investment is also addressed. Apart from the study of the five corporations, the report also comments on other dedicated corporate social investment programmes. The programmes of each of the five companies are contrasted with current and relevant documentation from the 1999 Business and Marketing Intelligence report. Graphs and tables complement this information. The findings reveal that there is little public relations involvement in corporate social investment initiatives because corporate social investment practitioners do not see the need for the involvement of public relations practitioners in all areas of their corporate social investment initiatives. The results of the interviews gives the reader a broad perspective of corporate social investment and public relations within each company. The findings suggest that the role of public relations needs to be re-examined in the new millennium.

- Description: Numerous informal houses have been built on and adjacent to a landfill in iBayi, Port Elizabeth, South Africa, which accepted domestic and industrial waste. Formal housing surrounds most of the site at a greater distance - some 60 m, or further, from the landfill. Both formal and informally housed residents complain of odours, burning eyes, sore throats and headaches - symptoms which they believed were caused by the landfill. The landfill gas and ambient air were analyzed to classify and quantify the VOCs (volatile organic compounds) emitted and then to compare the quantitative data with recognised standards to establish if the residents are at risk. Eighteen target (potentially hazardous) VOCs were quantified. A wide variety of compounds were detected in both the ambient air and landfill gas. The results of the VOC analyses were similar to those of other workers in both the qualitative and quantitative studies. The concentrations of the VOCs were mostly lower than the TLV (threshold limit values) values, but exceeded the MRLs (minimum recommended levels). The combined concentrations of the VOC’s in the ambient air either approached or exceeded the limit values for combined exposure thus indicating that a potential health hazard exists. One third of the VOCs were detected in both the ambient air and the subsurface gas, however, external pollution sources also appear to contribute to the VOC concentrations ambient air. Dangerously high methane concentrations were repeatedly detected in the landfill gas amongst the informal houses. There was a vast improvement in the aesthetic qualities of the landfill since the disposal restriction to accept only domestic refuse and building rubble in July 1997. The ambient air was less odorous and landfill site littered. Fewer informal recyclers were present and their concomitant squabbling over valuables had almost vanished. The management of the iBayi landfill holds much room for improvement. There is potential for serious injury or even death if no action is taken to remedy the problems at the iBayi landfill. A holistic solution will have to be found to make the landfill a safe neighbour. Some complementary analyses (such as pH, heavy metal concentrations in the water and sediments etc.) were performed on the leachate and water surrounding the landfill.

- Description: Research has been conducted on performance indicators in higher education institutions in a number of countries. However, in South Africa limited research in this field on a national level is available to the management of South African higher education institutions. The change in funding of these institutions has led to performance measurement becoming essential in order to justify the use of public funds. In order to obtain more relevant information about performance indicators in the South African context, a literature study was conducted to develop a questionnaire to test the concurrence of the importance of performance indicators in South African universities and technikons. The findings of the survey shows a high level of concurrence for the performance indicators identified in the literature study.

However, in South Africa limited research in this field on a national level is available to the management of South African higher education institutions. The change in funding of these institutions has led to performance measurement becoming essential in order to justify the use of public funds. In order to obtain more relevant information about performance indicators in the South African context, a literature study was conducted to develop a questionnaire to test the concurrence of the importance of performance indicators in South African universities and technikons. The findings of the survey shows a high level of concurrence for the performance indicators identified in the literature study.

- Description: To stay competitive and to be able to sell high-class products in the modern automobile production it is absolutely necessary to check the quality standard of a manufactured vehicle. The normal measurement strategy to check the quality standard of a completely assembled car is through a complex measurement strategy whilst the vehicle is in the actual series production. This is an immensely time and money consuming process. Furthermore, measurement systems are fixed within a certain position and the flexible measurement of a produced vehicle is very difficult to realize. This project presents a measurement system compliant to all quality guidelines, with which it is possible to measure any mounted component from a completely assembled vehicle wherever and whenever required. For the first time it is possible to measure the vehicle quality and dimensional standard from the first body in white prototype assembled in production up to the completely assembled vehicle delivered to the customer. The result of this project is a measurement system that consists of a hardware tool and a specially programmed software add-on. The complete system could easily be carried to the vehicle that must be analysed. This gives a lot of advantages. Furthermore it is possible to use this developed technology for the whole Volkswagen Company including the other brands like Audi, Skoda and Seat.

- Description: As an important part of a nation’s history and culture, South African wine industry contributes vastly towards South Africa’s economy and job creation. However, under the influence of the widespread globalisation, South African wineries have to face many new issues and challenges. How to expand their overseas markets and obtain a sustainable development mode has drawn more attention from South African entrepreneurs in this field. Due to the rapid economic development and the huge population, China can provide a market with enormous potential to South African wineries. The fast growing trade between the two countries can also bring opportunities to South African entrepreneurs to explore the Chinese market. Therefore, it is necessary and vital for South African wineries to understand the Chinese market and the factors that influence wine imports from South Africa before they enter the wine market in China. The research problem addressed in this study was to investigate the factors in the Chinese market that influence wine imports from South Africa. To achieve this objective, a literature study was undertaken to probe the various aspects of the wine market in China, including the characteristics, the status quo and the development trends of this market. The driving factors that attribute to a great increase in wine consumption in China were also explored and discussed. Based on the literature study, a survey questionnaire was developed to obtain the empirical data. By means of comparison and integration of the findings of the empirical survey with the literature study, the results were obtained for solving the research problems. In addition, conclusions and recommendations iii were drawn to assist South African wineries and other marketers in choosing appropriate marketing strategies and avoiding potential risks.

- Identifier: vital:9625 , http://hdl.handle.net/10948/721 , Lasers -- Industrial applications , Metal cladding
- Description: The research investigated the application of continuous coaxial laser cladding by powder injection as a surface treatment or coating process. The investigation aimed to establish the relationship between a change in the main laser cladding process variables and the geometry and characteristics of an Al-20wt-Si single pass clad layer formed on an Al 1370-F substrate using a Nd:YAG laser. The main process variables considered were: laser power, laser scanning velocity and the powder feed rate. The relationship between a change in the main laser cladding process variables and the geometry and characteristics of the clad layer was established by statistically analysing the variation in the process response with a change in the main laser cladding process variables. The process variables were varied based on a full-factorial, experimentally optimized test matrix. The clad geometry which is mainly defined by: the clad height, width, clad aspect ratio, depth of alloy penetration, and the clad root angle/wetting angle was investigated. In addition to the clad geometry several clad characteristics were investigated such as the dilution of the clad layer in the substrate material, the Vickers microhardness and microstructure of the clad crosssection, the powder efficiency of the process and the amount of visible defects. The study successfully established the relationship between the main laser cladding process variables and the clad geometry and characteristics. The secondary objective of establishing a suitable processing window by considering the relationship mentioned above was only partially met since it is believed that further refinement of the experimental cladding test setup and therefore also the experimental variable test levels is required.

- Description: With the growth in the use of technology in sports, there has been an improvement in sporting performances. Some may argue that the two go hand in hand, while others will write it off as coincidence. Nevertheless the use of technology in sport is seen on a daily basis. Cricket uses Hotspot, tennis uses Hawk-Eye and rugby uses slow motion video replays. In these sports codes, technology is already an aid to umpires. Little is known, however, about the technologies used to assist coaches in sports codes such as netball. This study investigated the factors impacting the introduction of information technology in the coaching of netball. The study commenced with using the term technology in the broader sense of the word to gain an understanding from netball coaches as to how technology could be incorporated into the sport. It was later narrowed down more specifically to computer technologies. The investigation was done at the Spar National Netball Championships in 2012, where coaches were surveyed about the preparation for the tournament of the provincial teams. The surveys included questions to coaches regarding the technologies used in preparation for a national tournament. The results obtained from the coaches were used to identify the current technologies used. Interviews were conducted after the analysis of the initial results to probe into the potential use of social media as a tool to assist coaches. Based on the results of the study, a number of factors that impact on the introduction of technology in the coaching of netball were identified. The factors and basic guidelines were validated through expert focus groups. Based on the findings from the experts, the factors and guidelines were refined. It is envisaged that the findings from this research can be used to assist netball coaches in deciding how to introduce the use of information technology into the sport.

- Description: The main objective of this dissertation was to investigate how cold rolling process parameters could be optimised to improve surface quality of the AA 3003 H22 treadbright coils. This treadbright product is one of Hulett Aluminium’s main products and is exported mainly to the North American market. One of its critical requirements is a defect-free bright surface. The literature review was conducted with particular focus on the effects of selected parameters or settings with respect to surface quality and a chapter outlining these aspects has been included. It was clear from the literature review that selected parameters do affect the surface quality and if adjusted accordingly can improve surface quality on treadbright coils. Subsequent chapters after the literature review outline how the tests were conducted, procedures followed and equipments used from the cold rolling machine to laboratories. Surface appearance results after each parameter was adjusted, showed that the surface quality did improve and even got better when other parameters like the colouring roll angle and percentage reduction were adjusted. Correct working limits within which each parameter would yield acceptable surface quality were also established. All experiments conducted had no influence on the microstructure of the metal as it remained the same throughout each experiment. The same has been found with the mechanical properties as percentage reductions experiments led to no change in tensile strength, proof strength and percentage elongation. In conclusion, this research has proved that cold rolling process parameters selected did affect the product surface quality. If controlled they can be used to optimise the surface quality on the treadbright product as required by Hulett Aluminium and its customers.
