Thesis (Ph.D. (Marketing))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Economic & Business Sciences, 2017 / The purpose of this research was to study the relationship between firm‟s commitment to green, green marketing capability, green relationship learning, green human resource investments and firm performance for electronics manufacturers in South Africa. Despite the increased focus on on green marketing, there has been little focus on research relating corporate commitment to green and how it relates to green marketing capabilities and firm performance. This study fills this research gap by proposing and testing hypotheses relating firm commitment to green, green marketing capability, green relationship learning, green human capital investment and a firm‟s performance. To answer the research questions, primary data for n=212 respondents covering a range in firm size, gender, race, and age for electronics manufacturers in South Africa was used to test the hypothesis relating corporate commitment to green, green marketing capability, and a firm‟sperformance. The structural equation modeling approach was used to test the model fit and hypothesis testing. The software SPSS 24 was used to analyse the descriptive statistics and AMOS 24 was used to test the research model. The results showed that firm commitment to green was a predictor of firm performance and green marketing capability, green relationship learning, and green human capital investments was found to be mediators in the relationship between firm commitment to green and firm performance. Indeed, the hypotheses stated in this study were found to be true. The main contribution of this study is showing how corporate governance commitment to green can enable firm performance (both marketing and financial) through mediating variables of green marketing capability, green relationship learning and green human capital investment. The study further shows that corporate commitment to green influences green corporate social investment positively. Key words: corporate commitment to green, green marketing capability, green relationship learning, green Human Capital Investment, Green CSI, firm performance / GR2018

A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Management specialising in Entrepreneurship and New Venture Creation Johannesburg, 2017 / Globally, information communication technologies (ICT) have experienced rapid growth since the 1990’s. In South Africa, information communication technology now accounts for a larger percentage of the Gross Domestic Product than other sectors. Thus, ICT is an important driver of entrepreneurship, employment creation and economic development in SA. As such, one of the critical questions is how to ensure the competitiveness and performance of ICT firms. Entrepreneurship studies argue that the performance of entrepreneurial firms is affected by, amongst other things, the firms’ social capital such as formal networks. This study, therefore, examined the impact of formal networks on firm entrepreneurial performance of ICT firms in SA, paying specific attention to weak ties as well as the moderating role of the environment. The study adopted a positivist paradigm which relied on quantitative data, using a descriptive survey method. Applying probability sampling, a sample of 120 firms were surveyed from an industry database, achieving a 14% response rate. This response rate is adequate for the generalisation of the results (Urban & Sefalafala, 2015). In analysing the data, factor analysis to reduce several variables into latent factors was performed. Thereafter, statistical linear regression modelling was performed using the continuous dependent variable – Firm Entrepreneurial Performance indicated by: Growth in Sales and Market Share, and Profitability; and the continuous independent variable of Formal Networking indicated by: Network Tie Strength and Relationship Quality and Nature sub-constructs. The results demonstrate significant correlation between formal networking and firm entrepreneurial performance as well as weak ties. However, the results indicate no evidence for the moderating role of the environment. At a theoretical level, this shows that formal networking and weak ties are beneficial to ICT firms but the environment is a contingent factor. At a practical level, managers and firm owners should consider joining formal networks that promote weak tie relationships in order to access complementary assets and valuable information. Policy makers and other stakeholders should devise policies and programmes that support entrepreneurial ICT firms to engage in formal networking. The limitations of the study include the following: first, the study was cross sectional and limited to ICT firms on an industry database; second, the control variables did not include firm size. Future research should consider a longitudinal study to test the long-term impact of firm entrepreneurial behaviour as well as firm size to inform firm specific research. More studies should test the moderating role of environment. / MT 2017

Thesis (M.Dev.) -- University of Limpopo, 2011 / The mining sector in South Africa has enjoyed decades of profiteering and unchecked neglect of developmental needs of surrounding communities. Most of the communities surrounding South African mines are therefore synonymous with social problems that include poverty, poor health, unemployment, adult illiteracy, poor housing, family disorganization and high influx of unaccompanied migrant labour. On the contrary, mining is presented as the paradigm of wealth in particular when dealing with gold and diamond mining, while its marketing conceals its terrible social and environmental consequences. However mining is responsible for such impacts and many others. This study looks at the socio-economic impact of mining on community development in Greater Tubatse Municipal area located in Limpopo Province, South Africa. From the interviews conducted and questionnaires administered to sampled community members and workers of the platinum mine in Greater Tubatse Municipality, it emerged that the existence of mining companies in the area has done little to uplift the lives of the people in terms of socioeconomic development. The study makes recommendations on how the situation can be improved so that the population living in the area can benefit from the work carried out by mining companies.

Thesis (M.Sc. ( Agricultural Economics )) --University of Limpopo, 2005 / The deregulation of agricultural markets in South Africa led to the establishment of a futures market for agricultural products, which was opened in January 1995. The marketing of Agricultural products act No. 47 of 1996 was passed at the end of 1996. The new Marketing of Agricultural Products Act (Act No. 47 of 1996) in South Africa has created an environment in which farmers, traders and processors are able to react positively to transparent prices that are market related. Agricultural futures markets serve several important functions, such as price risk management, price discovery and forward pricing. Economists around the world have studied vertical and spatial price relationships, and the behaviour of price changes in futures markets using asymmetry tests. Price asymmetry results in futures markets have a number of important implications. Firstly, traditional models in time series may be slightly biased when forecasting future prices, because they assume price symmetry. Secondly, asymmetry results may imply that the weak-form efficient markets hypothesis appears to be contradicted, thus indicating that past prices do affect current prices and do contain information. Lastly, if persistent asymmetry is found in futures markets, market regulators and policy makers may wish to use asymmetric information to improve the functioning and stability of futures markets through improved price limit and margin policies. Implementing policies iv accounting for asymmetric behaviour may help avoid market crashes and sudden unexpected price adjustments adversely affecting market participants. This study tests the existence of price asymmetry in South African futures markets for white and yellow maize, wheat and sunflower seeds using a dynamic price asymmetry model. The sum of coefficients test and the speed of adjustment test are used to determine whether or not prices move up in the same fashion as they move down, over daily and weekly data frequencies. Out of the four commodity futures markets studied over varying data frequencies, only daily wheat is price asymmetric. Wheat daily prices respond faster to price decreases than to price increases. The implication of the results is that past prices do affect current prices and contain information. Hence, the weak-form efficient market hypothesis appears to be contradicted for wheat futures market. Another important implication of the results is that implementing policies accounting for asymmetric behavior through price limit and margin policies will improve the functioning and stability of wheat futures market in South Africa. / National Research Foundation, and the University of Limpopo

Thesis (M.Sc (Physiology)) --University of Limpopo, 2015 / Objective This study assesses whether noise levels above legal limits of 85 dB(A) that can result in noise-induced hearing loss are present in areas where employees are supposed to work and to verify that such areas are demarcated as noise zones at the Polokwane Platinum Smelter. Background and motivation Excessive noise is a global health hazard with considerable social and physiological impact, including the development of noise-induced hearing loss (NIHL). Noise is a major hazard in many workplaces. It is estimated that more than 30 million workers (almost 1 in 10) are exposed to unsafe noise in their work places. NIHL is the second most self-reported occupational illness or injury in the United States. Amongst miners, more than 90% of the population reports hearing problems by the age of 55 years. Noise exposure is prevalent in construction, foundries, agriculture, transport, industry and mining-related activities. The prevalence of NIHL has not changed much in the past two decades. Therefore, a hearing conservation programme is an important issue in the smelter as certain areas are denoted as noise areas. Study design A cross-sectional study design with a group of utility workers at the Polokwane Platinum Smelter, as the experimental group, and a group of undergraduate Bachelor of Science students at the University of Limpopo (Turfloop Campus) served as a control group. Method A sound level meter was used to measure the noise levels where the utility group performs their technical work. Data were analysed using the Statistical Package for the Social Sciences (SPSS) computer program. Results The average noise measured in various locations of the Polokwane Platinum Smelter was between 62.6 dB(A) and 105.1 dB(A). The results indicated that workers at the Polokwane Platinum Smelter are over exposed to noise in certain work areas if they work eight hours in the area. Areas where the average noise level was above noise rating limit of 85 dB(A) were demarcated as noise zones as an additional protective measure. Employees also use hearing protective devices, when they are working in noise zones, to control personal noise exposure. This is in accordance with the Occupational Health and Safety Act No. 85 of 1993 as amended eleventh edition (OHS Act 85/93). Conclusion In the present study, noise levels in certain areas exceeded the noise rating limit of 85 dB(A). However such areas are clearly demarcated as noise areas and employees accessing those area must wear earmuffs or earplugs. Possibilities of employees developing hearing loss overtime exist, if employees work for eight hours or longer in demarcated areas and do not adhere to the existing Hearing Conservation Program (HCP) implemented at the Polokwane Platinum Smelter. Noise levels at the Polokwane Platinum Smelter should be monitored regularly. / University of Limpopo

Thesis (MCom. (Accounting)) -- University of Limpopo, 2014 / This study explored the impact of Environmental Management Practices on firm financial performance through a case study of selected JSE SRI South African mining companies. Previous studies focused more on disclosure or international research but none focused on this impact in JSE SRI South African mining firms hence this study attempted to fill this gap. Using a mixed methods approach, the study examined whether the firms’ carbon emissions, energy usage and water usage had any impact on the firms’ return on equity. The study concluded that Environmental Management Practices did impact firms’ financial performance and offers many opportunities for academia, industry, managers, regulators and society to use these findings as a means for more research into and better understanding of these environmental management practices and their potential benefits to society.

Submitted in fulfilment for the requirements of the degree of Master of Technology: Business Administration in the Faculty of Management Sciences at the Durban University of Technology, 2009. / Competition is increasing as trading borders continue to widen in this global marketplace. As a result, South African organisations need to improve their efficiencies. The primary objective of the study was to examine the effectiveness of the Lean Enterprise Strategy (LES) at improving business efficiency, in the electrical pre-payment industry in KZN. Several underlying objectives which support the primary objective were examined and realtionships established. Two forms of empirical studies, observation and questionaire based, were used. These studies provided substantive findings which were analysed and interpreted. A positive relationship between the LES and business efficiency were established and the various underlying objectives addressed. Communication was found to be inadequate and highlighted. It was also found that there is a substantial delay in return on investments; therefore, sustainability should be targeted and the LES should have a continual re-cycling mechanism, which allows it not only to be sustainable, but also renewable.

Low-voltage switchgear and controlgear assemblies with a rated short-circuit withstand strength above 10 kA, are required, by law, to conform to the South African standard, SANS 1473-1 (Low Voltage Switchgear and Controlgear Assemblies: Part 1: Typetested, partially type-tested and specially tested assemblies with rated short-circuit withstand strength above lOkA). Standard SANS 1473-1 stipulates three categories of assemblies i.e. type-tested, partially type-tested and specially tested assemblies. The specially tested assembly is unique to the South African market, while the other two categories are stipulated in standard SANS IEC 60439-1 (Low Voltage Switchgear and Controlgear Assemblies: Part 1: Type-tested and partially type-tested assemblies), which is internationally accepted in many countries as the applicable low-voltage assembly standard. Standard SANS 1473-1 specifies seven type-tests for certification as a type-tested assembly (TTA), but specifies, at most, three type-tests for certification as a specially tested assembly (STA). The underlying purpose of a technical standard is to provide for the safety of people and property, with the purpose of the research being twofold: 1. To investigate if the testing requirements specified for a specially tested assembly (STA), in accordance with standard SANS 1473-1, are correctly applied, and do not pose any safety risks. 2. To investigate any safety risks that stem from the fact that four type-tests are excluded for verification as a specially tested assembly (STA), as opposed to the seven type tests required for verification as a type-tested assembly (TTA). The document highlights the technical inadequacies of an assembly that is certified as a STA, in accordance with standard SANS 1473-1, and the potential safety risks associated with this type of assembly classification. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2004.

There are a number of challenges that are facing the South African manufacturing industry today. Companies within this sector are trying all they can to ensure the optimal utilisation of physical and human resources and the maximisation of profit, all this at a very minimal possible cost. Each company within the industry is struggling for a competitive edge and bigger market share compared to other companies manufacturing the same product. Haas et al. (2005: 1) suggest that the manufacturing companies need more flexible labour strategies, like multiskilling, as a way of dealing with these challenges. Hulett Aluminium (Pty) Ltd, South Africa's largest aluminium producer and based in Pietermaritzburg, was used by the researcher as a case study. The company was founded in 1946 as a subsidiary of the international Alcan Aluminium Group. It is South Africa's largest manufacturer of semi-fabricated and finished aluminium products. The company introduced multiskilling in 2000, the main objective being to equip the employees with a variety of skills for the benefit of both the company and the employees themselves. This research study was undertaken to establish the extent to which Hulett Aluminium (Pty) Ltd has taken advantage of the theoretical benefits associated with multiskilling. To achieve this the following issues were investigated: preparation of a suitable environment for the application of multiskilling, effects of new, advanced technology on multiskilling, effects of absenteeism due to workshops, training programmes and personal matters, productivity levels, labour turnover, labour costs, trend towards selfmanaged groups, job satisfaction , employee motivation and industrial conflicts. This study first discussed the theoretical perspectives on multiskilling. This is followed by the description of Hulett Aluminium (Pty) Ltd, with specific description of the company's profile, the organisational structure, the aluminium supply chain and the company's core business . The description of the company is followed by the methodology used for the collection of data as well as the outline of the interpretation procedures followed. Research findings and discussion are also given. The key findings of this study are that both managers and shop floor employees at Hulett Aluminium agree that multiskilling contributes to increased organisational labour productivity, reduced organisational overall costs, and reduced industrial conflicts. Other areas of agreement include the fact that multiskilled employees need appropriate resources for the application of their skills; training is an essential tool for multiskilling and that rewards for a multiskilled workforce are a motivating factor for in the workplace. The final conclusion drawn is that much as Hulett Aluminium (Pty) Ltd has embraced multiskilling, there is still a lot the company needs to do or improve on, so that it could enjoy the benefits of the programme. Based on the findings of this study, some of the recommendations made for Hulett Aluminium are: • A detailed planning process for proper implementation ofmuItiskilling • All the relevant stakeholders within the company should be part and parcel of the implementation of the programme • Benchmarking with other manufacturing companies which have implemented multiskilling • Training of new recruits so that they could be at equal par with the old employees and also contribute positively to increased organisational productivity. 11 / Thesis (MBA)-University of KwaZulu-Natal, Pietermaritzburg, 2006.
