A hydrogeological assessment of the Uitenhage-Coega artesian system

Venables, Anthony John January 1985 (has links)
The Uitenhage artesian aquifer north-west of Port Elizabeth in South Africa, is one of the few artesian groundwater systems in Southern Africa. The Uitenhage - Coega, and Kruis River areas, are the most important portions of the Uitenhage Artesian System in terms of water abstraction and water use. This study concentrates on the Uitenhage - Coega area and in particular, on the Coega Ridge where the Table Mountain Sandstone (TNS) aquifer occurs at relatively shallow depths. The investigation is aimed at assessing the geological, hydrogeological and hydrochemical characteristics of the HIS and any other aquifers present, with the object of providing quantitative data for use in future decisions on the water resource management of the area. In order to achieve these objectives, field work, involving a hydrocensus, geological mapping, geophysical exploration, drilling, aquifer testing and hydrochemical sampling was carried out. Analysis of these data provided information on the extent of the aquifers, their hydrogeological characteristics and the chemical nature of the various groundwater types.

A geographical study of the Cape Midlands and Eastern Karoo area with reference to the physiography and elements of land use

Badenhorst, J J 14 November 2013 (has links)
The subject has been approached in the conventional geographic manner in successive chapters, Relief, Geology, Soil, Climate, etc. In practice, the relationship between geographic factors and land use is so close that it is usually very difficult to separate the one from the other. When there is any reference to a specific relationship in any chapter, it must be borne in mind that one must always take the other geographic factors into account. In this study the stress falls on an evaluation of the present land use. Even if there is no recommendation regarding the way in which the land should be used, this survey can still be used as the basis for future planning.

Photographing other selves: collecting, collections and collaborative visual identity

Minkley, Hannah Smith January 2016 (has links)
This study is situated in a social documentary photography context, and is concerned to explore whether the collaborative interaction between photographer, subject (as collector) and material object (as collection) might enable a practice that presents a more mutual and subject-centred visual identity emerge. In particular, photographers Jim Goldberg and Gideon Mendel have focused more on the subject themselves, using collaborative processes such as photo-voice and photo elicitation, as well as the use of peoples’ handwritten captions on photographic prints themselves. Claudia Mitchell’s overview of visual methodologies is drawn on, together with Ken Plummer’s Documents of Life 2 (2001) and Gillian Rose’s Visual Methodologies (2001) to extend on these possibilities of conducting collaborative visual research.The practical component of this study focuses on personal collections and follows a number of theorists, including Susan Pearce, and John Elsner and Roger Cardinal. It follows Pearce’s identification of three major modes of collecting, and suggests that collections are essentially narratives of the self, and reveal experiences and expressions of personal desire. By drawing on these approaches and the various ways the twelve collectors were photographed, as well as implementing collaborative research processes (handwritten text, archival photographs and the re-staging of the collections), the study confirms Pearce’s three primary modes of collecting, and acknowledges that they are often interlinked or overlap one another. The study further found that a more subject voiced visual identity did indeed become apparent through the collaborative methods applied and discussed. The collaborative research equally demonstrated that these narratives of identity are not singular, but rather narratives of multiple, personal identities of the self.

Wireless ICT monitoring for hydroponic agriculture

Ndame, Loic Andre Stephane January 2015 (has links)
It is becoming increasingly evident that agriculture is playing a pivotal role in the socio-economic development of South Africa. The agricultural sector is important because it contributes approximately 2% to the gross domestic product of the country. However, many factors impact on the sustainability of traditional agriculture in South Africa. Unpredictable climatic conditions, land degradation and a lack of information and awareness of innovative farming solutions are among the factors plaguing the South African agricultural landscape. Various farming techniques have been looked at in order to mitigate these challenges. Among these interventions are the introduction of organic agriculture, greenhouse agriculture and hydroponic agriculture, which is the focus area of this study. Hydroponic agriculture is a method of precision agriculture where plants are grown in a mineral nutrient solution instead labour- intensive activity that requires an incessant monitoring of the farm environment in order to ensure a successful harvest. Hydroponic agriculture, however, presents a number of challenges that can be mitigated by leveraging the recent mobile Information and Communication Technologies (ICTs) breakthroughs. This dissertation reports on the development of a wireless ICT monitoring application for hydroponic agriculture: HydroWatcher mobile app. HydroWatcher is a complex system that is composed of several interlacing parts and this study will be focusing on the development of the mobile app, the front-end of the system. This focus is motivated by the fact that in such systems the front-end, being the part that the users interact with, is critical for the acceptance of the system. However, in order to design and develop any part of HydroWatcher, it is crucial to understand the context of hydroponic agriculture in South Africa. Therefore, complementary objectives of this study are to identify the critical factors that impact hydroponic agriculture as well as the challenges faced by hydroponic farmers in South Africa. Thus, it leads to the elicitation of the requirements for the design and development of HydroWatcher. This study followed a mixed methods approach, including interviews, observations, exploration of hydroponic farming, to collect the data, which will best enable the researcher to understand the activities relating to hydroponic agriculture. A qualitative content analysis was followed to analyse the data and to constitute the requirements for the system and later to assert their applicability to the mobile app. HydroWatcher proposes to couple recent advances in mobile technology development, like the Android platform, with the contemporary advances in electronics necessary for the creation of wireless sensor nodes, as well as Human Computer interaction guidelines tailored for developing countries, in order to boost the user experience.

Investigating the high level of consumer indebtedness in the South African retail market

Kgomo, Stephen Phuti January 2016 (has links)
This study was aimed at investigating the high level of consumer indebtedness in the South African retail market more specifically factors that contribute to consumer indebtedness. Recommendations on how to control the level of consumer indebtedness are also presented. Consumer indebtedness is a problem in many countries around the world and as witnessed during the 2008 global financial crisis, its impact can be disastrous. Not only does it create problems for the families but also for a country and even to the extent of the whole world. The literature conducted did not reveal a study undertaken to investigate factors that impact consumer indebtedness. Eight factors were identified and explored further in this study. Results were analysed in chapter three and outcomes presented in chapter four. The method used in conducting this study is the quantitative method. A questionnaire was developed based on the literature review conducted. The questionnaire was a five point Likert scale and was distributed to the respondents in the southern area of Tshwane Municipal district. In view of a manageable number of responses, results were analysed using an excel spreadsheet. Results were verified by an independent expert. From the eight factors that are identified, one (easy access to credit) was found to impact the high level of consumer indebtedness. Although there are other weaknesses, easy access to credit is found to be the main contributor. Recommendations on the findings are presented in chapter five of this study.

The taxability of rewards from suppliers

Akoonjie, Ahmed Hassen January 2016 (has links)
Successful business in today’s competitive climate thrives on building relationships with one’s suppliers, clientele and employees. Businesses, as a form of strategic engagement, extend their appreciation and recognition to these key role players with rewards (or incentives) such as prizes, holidays and free goods and/or services. This treatise examines the taxation implications of such rewards and determines that the market value thereof should be taxed in the hands of their recipients. This study also investigates possible indicators (or points of reference) to establish such market value and suggests alternate values that may be ascribed thereto for inclusion in the recipient’s gross income. Where the rewards are passed onwards by the recipient to its employees, fringe benefit consequences are occasioned and this study observes that the market value thereof should be taxed in the employees’ hands. The study goes on further to consider the position of the supplier (or provider) of the rewards and finds that the supplier is entitled to a deduction of the cost of the rewards it has provided to its clients or customers. This study also reflects upon the penal implications of not including the market value of rewards in gross income and notes that such non-inclusion constitutes a fiscal loss and is subject to an understatement penalty. Key recommendations on how such omission may be addressed by the tax authorities are also presented.

Research into entrepreneurship and small business in South Africa: current status and future challenges

Tai-Hing, Paul January 2012 (has links)
This research seeks to advance knowledge of the current state of entrepreneurship and small businesses in South Africa, and reports on a review of 32 articles and 244 research abstracts in the field. The studies as a whole indicate that entrepreneurs in South Africa require more knowledge in the fields of: Networking in business, Internationalisation of business, Entrepreneurship training. Since the 1990s, research in entrepreneurship has grown in terms of the number of articles published and conference papers presented. In many countries entrepreneurship has also become part of the political agenda as it is perceived as a possible solution to high unemployment rates. In addition, interest in entrepreneurship has heightened during the 2000s, especially in business schools. Much of this interest is driven by student demand for courses in entrepreneurship, either because of genuine interest in the subject, or because students see entrepreneurship education as a useful hedge given uncertain corporate careers. Most of the entrepreneurship research abstracts reviewed for this study focused on race, gender and ethical issues in South Africa. These three research topics focused on: Attitudes and experiences of black women: differ from other racial groups in business with the results indicating that black women were competent and highly-motivated, but lacked communication skills and Western business orientation. Many black women also desired equality although their male counterparts opposed this. Black women also lacked role models and career guidance. Different population groups participate in the economy: reflect regional, income, expenditure, skill, occupational and labour differences, including labour supply and demand. Ethics concerns: include whether it should be taught in the human resources management curricula taught in universities. From the findings it appeared that entrepreneurship research in South Africa is fairly similar to international research contexts. As entrepreneurship and small businesses are diverse and multi-disciplinary, the studies reviewed indicated a wide range of different models, theories, frameworks, and combinations of these. However, the theoretical richness of the studies reviewed was, in many cases, relatively low, and only a few of the studies could be regarded as highly-theoretical. In addition, the presentation of the various theories and models applied was very often inadequately reported. It is also important to note that altogether between 7 and 11 percent of the studies were without any well-argued theoretical framework. Thus, researchers in the field should discuss the theoretical frameworks applied in their empirical analyses, to ensure this will improve the theoretical understanding of the phenomenon. Although this study made use of the mixed-method approach to conduct the research, it is also important to note that, in 12 percent of cases, methodological issues were poorly described. Most of the studies often did not describe the data collection response rate provide sample demographic and firm size details as well as identify the target industry. These details were often missing or loosely defined. The reasons for the selection of a certain research approach were also poorly explained, making many of the research studies deficient or limited methodologically. These omissions present a challenge, not only to authors in the field, but also to reviewers and editors in academic journals, as this impacts on the scientific rigor of published papers. On the basis of published papers reviewed, it seems that, personally-administered data collection works best in South Africa. From the research studies undertaken in South Africa, it is evident that much has been researched in the areas of gender (specifically the role of women in business), entrepreneurship training and ethics in business. It is evident that during the 1980s, no research was conducted in South Africa in the areas of family businesses and entrepreneurship training, while international research focuses on these topics. During the 1990s, no research focused on networking in small businesses, and. during the 2000s, there was a lack of research on internationalisation of businesses as only six articles were published from 2000 until 2011 on these topics. This highlights a need for internationalisation research especially as it is well-documented that the South African economy cannot survive if it does not take cognisance of its international competitors. On the basis of the articles and abstracts reviewed, the current state of knowledge concerning entrepreneurship and small businesses in South Africa was assessed, especially the need for the internationalisation of South African small businesses. Moreover, research studies could also focus on the obstacles encountered in the internationalisation process of South African small businesses.

Optimising the material distribution process for the southern region of Telkom SA

Naicker, Kosalin Ganasen January 2005 (has links)
Most government owned telecommunication operators across the world have to deal with a number of regulatory, technology and service challenges, as the industry is liberalised in co-ordinance with worldwide trends. Telkom SA will be facing a number of strategic challenges that will test its ability to survive as a telecommunications company over the next number of years. To remain competitive, Telkom must develop strategies to assure survival in a competitive environment. To assure the long-term survival of Telkom SA when moving into a competitive environment, the organisation must build a sustainable competitive advantage. In the face of increasingly fierce competition, the adoption of collaborative alliances between firms is becoming more and more common and the adoption of a world-class supply chain will be an ideal scenario for Telkom SA. A worldclass supply chain goes beyond the scope of the internal operations of an organisation, therefore the material distribution process was chosen for this study, which involved the internal operations in the organisation. The study included the availability of material up to the transportation of the material to the staging areas. The aim of this research was to identify the inefficiencies of the material distribution process of the Southern Region of Telkom SA to become worldclass. A quantitative technique was used to identify the inefficiencies. It was found that the availability and transportation of material were the inefficient categories, preventing the customer to receive the product or service on time. Communication, inaccurate forecasting and inefficient transportation of material were some of the reasons for not delivering material on time. Some of the recommendations included developing a model that could overcome the current inefficiencies in transportation, improving the communication channels, training and the development of employees at all levels.

The role of principals in the induction of new educators in their schools

Mfenqe, Phyllis Phindiwe January 2005 (has links)
This study focuses on the role of the induction programme for teachers who are new to a specific school. The main aim of undertaking this research study is to investigate the role played by principals in the induction of new educators in their schools. The main questions the study addresses are: · Why is it necessary for new educators to be inducted · How could mentoring play a role in an induction programme? · What should the role of the principals be in the induction process? · What should the induction programme include and how should it be implemented? The study highlights the problems new teachers experience with respect to aspects such as classroom control and imparting information. It also emphasizes the role of the principal and the mentor in assisting new educators with these issues. The qualitative approach was used to collect data. Data were collected through interviews and observations. The main findings were that new educators experienced problems with classroom control, discipline and that principals should help them with adjustment in the school by allocating a mentor teacher for support.

Assessing the statistical methodologies of business research in the South African context

Ndou, Aifheli Amos January 2011 (has links)
The aim of the study is to establish an acceptable classification scheme for the statistical methods used in business research. The approach compares the statistical component of the research and evaluates how it has changed over time and across different journals. If, as expected, the statistical expertise has changed, the change would be identified with the view to recommending curriculum changes for Statistics Departments of South African tertiary institutions.
