Generation Y entrepreneurs and social media platforms: an assessment of online entrepreneurial alliance creation.

Reinhart, Andrew Josef January 2017 (has links)
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 in Entrepreneurship and New Venture Creation, 2016 / This study was to identify the extent of Generation Y entrepreneurs’ social media usage in terms of weak-tie alliance maintenance and creation and also alliance creation. A sample group of entrepreneurs in the Johannesburg were chosen by using social media as a channel. By using the researcher’s social capital and also the different characteristics that are unique to these SNSs (social network sites), such as Twitter advertising, a sample group was created. A digital survey was distributed to the selected entrepreneurs by using an online platform. By using hypothesis testing and a multiple regression model, it was identified that entrepreneurs tend to favour maintaining weak-ties over creating weak-ties using SNSs, and alliance creation on SNSs does not seem too common, but it was highlighted that when entrepreneurs do create alliances, they tend to favour weakties that they have created on SNSs. The overall picture is that entrepreneurs have an inclination not to use SNSs to create weak-ties and alliances, this could come down to a number of factors such as trust and education, and there could also perhaps be no SNS that supports alliance creation to the extent that entrepreneurs need. / XL2018

The petrogenesis of the Koperberg suite in the jubilee mine, Namaqualand.

Van Zwieten, Adrianus Josephus Maria January 1996 (has links)
Thesis submitted for the degree MAGISTER SCIENTIAE to the Faculty of Science, Department of Geology, University of the Witwatersrand, Johannesburg / The Koperberg Suite intrusion at Jubilee, Namaqualand varies in composition from anorthosite, through mica diorite to pyroxene leucodiorite and pyroxene diorite. Detailed mapping and petrological studies of these rocks indicate that they were sequentially emplaced into the Concordia Granite country rocks, and that each of the rock types represent discrete magmatic events. The sequence of intrusion is from more acidic to more basic. Whole-rock geochemical analyses indicate that these rocks represent cumulates involving variable proportions of plagioclase, orthopyroxene, mica, quartz, oxides and immiscible sulphides. These cumulate phases intruded into the Concordia Granite at the time of peak of metamorphism and deformation in the Okiep Copper District, i.e, about 1030Ma ago, At the time of intrusion, the country rocks were under going partial melting under high grade (granulite facies) metamorphic conditions. and granitic anatects were present in the crust. Hybridisation of basic magma and granitic melts occurred within the shear zones along which the basic magmas ascended. The En content of orthopyroxene in the Koperberg Suite exceeds the An content of plagioclase. This is atypical of basic intrusions and is a consequence of this mixing. Mixing calculations based on the initial 87Sr/86Srratio (Ru) of the Jubilee samples at 1030Ma, imply high levels of assimilation (as much as 80% assimilation in the case of anorthositic rocks) between a granitic component, similar in composition to the Nababeep Gneiss and a mantle-derived basic magma. Sulphide mineralisation was initiated by the assimilation process, which caused the separation of immiscible sulphides from the hybridised magma. Subsequent oxidation of the original sulphide assemblage produced bornite, chalcopyrite and Ti-poor magnetite. / Andrew Chakane 2019

Human capital and entrepreneurial success in the context of South African informal economy

Ntuli, Tshikani Derrick January 2017 (has links)
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 / Existing literature indicates a positive relationship between human capital and entrepreneurial capital. This has been a dominant supported view for ages. Among other scholars, Unger, et al. (2011); Davidson and Honig (2003); still uphold the view that human capital influence entrepreneurial success to a certain magnitude. However, contemporary studies argue that although the relationship has been demonstrated for decades, some assumptions to the perception should be questioned as the world evolves over time. Unger (2011); Martin, et al. (2013), and more other scholars identify the modification of the traditional assumptions. In terms of these scholars, uncertainty remains over the magnitude of this relationship and the circumstances under which human capital is more or less strongly associated with entrepreneurial success. Consideration of fragmentation in today's study with regard to conceptualization of human capital, the choice of success indicators, the context of study provide some critical challenges to the traditional perception of consistent relationships. All these aspects provide some open gaps to be filled by research. Oostebreek, et al. (2010) sees a questionable relationship between human capital factors and entrepreneurial success, which in terms of Unger, et al. (2011) give rise for the consideration of a moderator approach to study the effects of human capital on business success in order to efficiently determine whether the stated relationships exist or not. Resourced-Based Theory (RBT) was used as theoretical framework to this study. Three main constructs and five sub-constructs have been used to formulate the conceptual model from which three hypotheses were developed and tested. Empirical studies was conducted among selected informal traders in Limpopo Province – focusing in three districts. 257 unregistered small business owners were potential respondents. A quantitative methodology was employed to collect and analyse data through survey research design. The Structural Equation Modelling (SEM) along with AMOS 23, SPSS were used as descriptive statistical tools to test the validity of the hypotheses. Both theoretical and applied implications will assist the knowledge-base of researches. Policymakers will also find the implications useful in industrial policymaking. This study provides recommendations which may assist further research and other related enquiries of academic nature. / MT2017

Classification of vegetation of the South African grassland biome

Ellery, William Nolan January 1992 (has links)
A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg 1992. / The aim of the study was to develop understanding of the relationships between vegetation types of the grassland biome of South Africa and the environment, with an emphasis on structural and functional characteristics. The grassland biome in South Africa has traditionally been divided into 'pure' grasslands, assumed to be climatically determined, and 'false' grasslands of recent anthropogenic origin. A review of literature from several disciplines including palaeobotany, archaeology, ecology and biogeography indicates that this is not a valid distinction. It is clear that the distribution of the grassland biome as a whole is poorly understood, but the general correlation between the distribution of biomes and climate elsewhere in the world suggests that this warrants more detailed investigation. A water balance approach was used to develop climatic incices that both predict the distribution of grasslands, and are easy to interpret biologically. The indices are the mean. number of days per annum when moisture is available for plant growth, tbe mean temperature on days when moisture is available for plant growth (wet season temperature),. and the mean temperature when moisture is not available for plant growth (dry season temperature). Based on these three.indices the grassland biome in South Africa call be distinguished from neighbouring biomes. The fynbos and succulent karoo biomes have rainfall in winter. The grassland, nama-karoo and savanna biomes have' rainfall in summer. The forest biome experiences rainfall throughout the year. Of the summer rainfall biomes, the quantity of water available in the grassland biome b greater than in the nama-woo, similar to savanna, but less than forest. Grasslands experience cooler dry season temperatures than savannas. The localised distribution of woody plants within the. grassland biome suggests that it is the effect of climate on the fire regime that may be of overriding importance h'l determining the distribution of the biome as a whole. Woody elements are restricted to sites that are either protected from fire, or experience fires of lower intensity than sites that support- grassland, The unifying feature of the grassland biome is its proneness to fire. The presence of a warm, moist season promotes plant production and leads to a high standing crop close to the ground. The prolonged dry season causes vegetation to dry out annually, rendering it flammable. More arid biomes have plants more widely spaced, making it difficult for fire to spread. In more mesic biomes where rainfall is less sea.sonal than in the grasslands or savannas, fuels do not dry out sufficiently to ignite, A number of additional climatic features may promote burning in the grassland biome, It has the highest lightning density of all South Africa's biomes. 'tVarm, dry 'berg' winds desiccate fuels and 1 omote burning in the more mesic grasslands, The 'curing' of the grass sward due to dry season frost and temperature drop is important in establishing early dry season flammability. Savanna trees are fire tolerant, but they appear sensitive to the cold temperatures prevaient in the grassland biome in. the dry season, The relationship between the distribution of functional characters of grassland plants and environmental conditions was investigated. The distincrion between sweetveld, mixed veld and sourveld was recognised as one of the most Important functional features of South Africa's grasslands, The distribution of these vegetation types was examined in detail. Sweetveld occurs In warm, dry areas; sourveld in cool, moist areas. There Is overlap between these tyP.Js that Is dependant on soil nutrient status. Sweetveld that occurs in climatic conditions that would be expected to support mixed veld and sourveld, is on soils derived from basic parent material, including basalt, dolerite, gabbro and norite. Similarly, sourveld that occurs in areas that climatically would be expected to support sweetveld, is on soils derived from acid parent material such as sandstone and quartzite .. Soil nutrients that are most highly correlated to the occurrence of these three veld types are phosphoms availability and an index of nitrogen mineralization potential. 'l'here is an increase in bot; available phosphorus and the index of readily mineralizable nitrogen from sourveld to mixed veld to sweetveld. These features am inc01).10111tedinto a conceptual model that relates the distribution of these grassland types to carbon and nitrogen metabolism, with the role of phosphorus either similar to nitrogen, or else it may act indirectly by affecting the. rate of nitrogen mineralization, Nitrogen mineralization OCcursat lower water availability than carbon assimilation, and its temperature optimum is higher than that of carbon assimilation.

The influence of social media political marketing on trust, loyalty and voting intention of youth voters in South Africa

Dabula, Nandi January 2016 (has links)
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 in the field of Strategic Marketing Johannesburg, 2016 / South Africa has witnessed a decline in youth voter turnout. Consequently, political parties are integrating social media in their political marketing strategies in order to appeal to the youth voters. Notwithstanding the cumulative research that has been conducted on social media political marketing globally, there is dearth of such research in South Africa. Furthermore, no studies have explored the influence of social media political marketing on voter trust, loyalty and voting intention of the youth in the South African political context. This research intends to contribute to the increasing knowledge on the efficacy of social media political marketing by political parties in South Africa to engage with the youth and improve their election turn out. The two main research objectives the study seeks to achieve are to establish the influence of social media political marketing on voting intention, with voter trust and voter loyalty as mediators and to determine which mediator (voter trust or voter loyalty) has the strongest influence on the outcome variable (voting intention). Using a data set of 250 respondents, between the ages of 18 and 35 years, from Gauteng Province in South Africa, this study explores these relationships. The study outcome is that all five hypotheses are supported. The results denote that the relationship between social media political marketing and voter trust, social media political marketing and voter loyalty, voter trust and voter loyalty, voter trust and voting intention and voter loyalty and voting intention are all positive in a significant way. The research paper deliberates on the implications of the results from an academic, political party, legal and marketers’ perspective. In addition, directions for future research are suggested. / MT2016

Assessing the impact of forms of entrepreneurial capital on corporate entrepreneurship in state-owned enterprises

Mpanza, Phelelani January 2016 (has links)
A dissertation submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Masters of Commerce in Business Science from the School of Economics and Business Sciences. Johannesburg South Africa / Increasing competition in industries has made it necessary for established companies to regenerate themselves and renew their ability to compete. This is the goal of Corporate Entrepreneurship (CE) activities, which involve extending the firm‟s domain of competence and corresponding opportunity set, through internally and externally resources. Recently, CE has evoked interest not only from academics, but also from business practitioners and policy makers. This interest stems from the recognition of the advantage that can be gained from corporate entrepreneurship activities (Entebang, Mansor, & Puah, (2006). The prominence of State Owned Enterprises (SOEs) in the economy continues to grow. Their assets have been growing steadily since 2011 while SOEs play a critical role in the economic pursuit of advancing economic growth and developmental objectives of the country (Brown, 2014). This dissertation assesses the impact of forms of capital on corporate entrepreneurship in State Owned Enterprises in South Africa. The focus is on three forms of entrepreneurial capital which are; (1) economic capital, (2) human capital, and (3) social capital. Each form of capital is critical and has been discussed in the literature in order to orientate its utility in relation to entrepreneurship. The study was carried out in three major SOEs, which are administered by the Department of Public Enterprises. The study was based on quantitative measures using a self-administrated questionnaire. It was found that some forms of capital have a significant impact on a company‟s entrepreneurial activities. For instance, it was found that forms of entrepreneurial capital have significant influence on corporate entrepreneurship because they contributed positive toward the growth of the business. This study considered the nature or the quality of the company‟s workforce by means of employee human capital. Therefore, of all the managerial processes that can affect the pursuit of corporate entrepreneurial outcomes, Human capital is considered as one of the more vital. Furthermore, the recent loan guarantees from government to SOEs such as Eskom and South African Airways are a practical indication on the level of importance Economic capital is on corporate entrepreneurial activities. On Social capital and Corporate Entrepreneurship, Foil (1995) argued that it is the access to a diverse set of firm resources that significantly enhances corporate entrepreneurship activities, which points to the importance of Social capital at multiple levels within the organisations in pursuing corporate entrepreneurship. However, more research is required to investigate further how forms of capital impact established company‟s entrepreneurial activities. / MT2017

The impact of e-word-of-mouth, engagement and brand image on soccer fans' intention to purchase football tickets

Nhlabathi, Mthobisi Patric January 2016 (has links)
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 in Strategic Marketing, Johannesburg, 2016 / This study was conducted with the aim of investigating the influence electronic word of mouth (e-WOM) engagement and brand image have on purchase intention. The study was based on understanding factors influencing football fans’ consumption behaviour in relation to sports, specifically football. The study involved different aspects, including the impact of social media and branding on consumer behaviour. The literature consulted assisted with conceptual model and hypotheses development, around which the study was centred. Data for this study was collected from 260 Orlando Pirates FC fans at the Sebokeng branch, where participants were all supporters of the football club which was the subject of the study. Data was collected through a self-administered survey. Using the SPSS 22 and AMOS 22 packages to analyses the data, all the hypotheses were confirmed at 99% confidence level. E-WOM proved to be the most influential factor on fans’ consumer behaviour towards purchase intention while engagement showed the least. The conclusion and recommendation section was informed by the results following the data analyses. Recommendations which emanated from the findings were split between marketing practitioners and academic researchers. Maintaining a positive brand perception proved to be beneficial for brands based on the outcomes of the study. The outcomes also proved that the participant ranked engagement on the club’s Facebook page as the lowest factor t influence their consumer behaviour. As there are few studies on fans’ consumption behaviour in the sports environment, let alone football in South Africa, it would be interesting to see more studies done in this field in future. / GR2018

Socio-economic processes in the rural areas of Region E

May, Julian January 1900 (has links)
The social conditions in the rural areas of South Africa are by now widely known and numerous researchers have documented the poverty stricken quality of life which generally prevails amongst black families in these areas (Wilson and Ramphele, 1989). The vast majority of rural households have incomes which are below subsistence levels and in the Homelands, agricultural productive ability has become so eroded that rural household income is now chiefly derived from remittances from migrants in the towns or from the wages of farm labourers (Nattrass and May, 1986). As such, at present the majority of black rural households living in Region E make up consumer communities which must purchase the majority of their subsistence needs, rather than producer communities in which subsistence needs can be met from the utilisation of local resources (Derman and Poultney, 1983). Despite this unpromising situation, the diminishing importance of agricultural production to the South African national economy (Bethlehem, 1989), and the dominance of urbanisation as a social force, it can be argued that the rural areas of Region E will be directly and substantially affected by efforts to restructure the South African economy as a whole. Consequently, revitalising the rural economy in a restructured social and economic system would be a concern in itself, even though the effect of this for a future growth path for South Africa may be uncertain (Kaplinsky, 1991:54). The report will first examine the broad demographic changes in Region E noting the impact of these changes on the rural areas. Thereafter, the economic processes which characterise the rural areas will be discussed, in particular, employment, income levels and income distribution. This will feed into a discussion of the social processes which will include changing dynamics of migration, and a socio-economic profile of rural households. The paper concludes by briefly examining access and usage of basic services and facilities in the rural parts of Region E.

Resisting racism: a teachers' guide to equality in education

Eyber, Carola, Dyer, Dorothy, Versfeld, Ruth January 1997 (has links)
While South Africa's new democracy has meant that schools are now open to all, there is still racism in our schools. The changes in schools have in some cases exacerbated racial tensions and mistrust. Teachers everywhere are struggling with the changing dynamics of their classrooms and schools. There is much talk about how to work against racism. Various programmes and schools have developed different ways of dealing with it. All have particular ideas about how best to counter it. Resisting Racism aims to discuss and understand the beliefs and assumptions underlying many of these approaches. We look at the theories behind the different practices, present a range of ideas to illustrate them and consider their limits and possibilities. The book is a starting point for teachers and schools to reflect on their practices and help them to work out new strategies in the classroom and school. The approaches described will probably work best if they are used together, specially adapted to the specific context in which they are to be used. In the first part of the book we look at psychological and sociological explanations of why people are racist. Four different ways of looking at the issues are described. Each suggests practical ways of dealing with racism in the classroom and in the school. Chapter Three, on multi-cultural and anti-racist education, covers similar ground but from a slightly different angle, looking at curriculum debates about race, culture and equality. The final section looks at the concerns that many teachers have every day, such as "How can I deal with the language problem?" and "How can I involve parents in these issues?" In discussing these questions we have tried to use current theory to inform the practical ideas suggested. You will discover that this book is not neutral. It does have a point of view. It seeks to explain the limitations of assimilating students into a status quo and asks that schools take a critical look at their policies and practices. There are no easy answers or quick solutions. However thinking about and understanding the issues of racism and the ways in which it may be resisted can only bring us closer to positive change.

The economic rationale and modalities for rural infrastructure development: developmental local government in rural service delivery

Stilwell, Ted, Atkinson, Doreen 09 1900 (has links)
The Policy Unit of the Development Bank of Southern Africa (DBSA) has developed a number of strategic themes embracing many cross-cutting issues. The main thrust of the Unit’s work, however, focuses on the core mandate of the Bank - infrastructure. In order to provide for a coherent whole, rural infrastructure must fit into a broader policy framework. Globally, the goals set for the first two decades of the next millennium are to address poverty and achieve food security. The DBSA can contribute to South Africa’s position on these global themes by addressing the issue of rural infrastructure delivery, taking cognisance of the South African government’s Growth, Employment and Redistribution (GEAR) programme. This discussion document will specifically address the local economic development activities of farm production and rural livelihoods in order to achieve food security, address poverty and foster economic growth in the marginalised, infrastructure-deprived rural areas of the country. It is assumed that additional entrepreneurial economic opportunities will arise at village and town level as producers become nett surplus producers, eg in small grain milling, cottage industry, village markets, processing (value adding), etc. In contrast to urban development, where economic activity is assumed by investing in infrastructure, the DBSA will actively have to support the transformation of economic activity in the rural scenario. One of the past successes of the DBSA has been the introduction of the Farmer Support Programme (FSP). The FSP’s provision of services and support, based on the needs of existing smallholders, is embedded in participatory planning and action. Without local initiatives, rural infrastructure cannot be delivered effectively to bolster economic growth, create jobs and redistribute income. Most of the country’s poor live in rural areas, and without rural development there can be no GEAR. Life in these areas needs to be made liveable by encouraging entrepreneurial development, which includes facilitating agriculture, creating jobs and increasing rural income through appropriate government actions for improving the welfare of rural households. One of the ways in which national, provincial and local government could have a broad-based impact is by providing rural economic infrastructure and, to this end, local government, including regional and district councils, has been mandated to develop integrated development plans. These plans have to include economic development plans, and entrepreneurial development has been singled out as important in this regard. From this it follows that district councils and municipalities have a prime responsibility for developing entrepreneurs, including farmers in their rural constituency.
