Thesis (PhD(Economics))--University of Pretoria, 2008. / Includes bibliographical references.

This academic discourse is a research treatise that is submitted in fulfilment of the requirements for the Masters in Business Administration (MBA) degree at the Nelson Mandela Metropolitan University (NMMU). Purpose – The purpose of this treatise is to develop four possible scenarios for Africa’s economic futures over the next 40 years, i.e. towards 2055. This study will expose the possible, probable, plausible, and preferable (desirable) scenarios for Africa towards 2055. Design/Methodology/Approach – This study employs a Futures Studies methodology that is known as scenario planning. The key variables of the scenarios are clustered as follows: Good governance and good economic growth; Good governance and bad economic growth; Bad governance and bad economic growth; as well as bad governance and good economic growth. Each of these scenarios begin with the current state of affairs in Africa. As such, the four scenarios in this study are informed by the current affairs in African countries as is internationally observed by scientists, researchers, as well as global views and opinions. Practical implications – This academic discourse provides useful insight into the causality relationship between the political, economic, sociological, technological, ecological, as well as legal factors (PESTEL factors) on the continent and the possible scenarios for Africa’s economic futures towards 2055. The aforementioned causality relationship between the abovementioned variables allows for insight into the drivers for change for Africa as well as in what way to anticipate these changes in accordance with scenario planning. Originality/Value: This treatise looks at the economic futures of Africa over the next 40 years from the point of view of African planners and African decision-makers.

M.Com. (Economics) / The main purpose of this study was the descriptive analysis and theoretical evaluation of various economic forecasting techniques applicable to a wide variety of forecasting problems. A comprehensive review was given of the basic structure of the techniques (theory and mechanics). their appropriateness ,In different forecasting circumstances, their technical and other limitations, advantages and disadvantages, together with a guide to the better understanding and interpretation of their results. Many of the problem areas related to economic forecasting can be avoided or at least alleviated, by a proper study of the adequacy and other distinguishing characteristics of a specific forecasting methodology. Forecasting accuracy is a major interest of anyone concerned with the future. There are many different ways of saying that the future belongs to those who plan for It best. This Is certainly true in economics as the practice thereof is filled with uncertainties. The topic of this dissertation is, therefore, very relevant In today's modern world. Diagnosis and forecasting have become inevitable with the growth of the" risk factor" In this world. Efforts are constantly made to eliminate, neutralize or at least decrease as far as possible, the risk attendant to this uncertainty by accurately predicting the future values of important variables. The importance and need for improved economic forecasting has, without a doubt, grown tremendously in recent years. The list of forecasting application Is quite lengthy as virtually every important operating decision depends to some extent on a forecast. Probably the simplest definition of forecasting is that it Is a process which has as its objective the explaining and prediction of events or conditions which will occur at some future time. More precisely, economic forecasting attempts to predict the change In Important economic phenomena. The forecast must however not be seen as an end product, but rather as an ongoing process of input In the decision-making process. Forecasting Is both an art and a science, but although II is a form of art it Is not without structure. As with any worthwhile art form. the forecasting process Is definitive and systematic. A number of special tools and techniques can be used In predicting the future " values of economic variables. The objective selection among these forecasting techniques is extremely difficult. The many different types of forecasting methods available can be grouped into two main categories: (i) the qualitative forecasting methods and (II) the quantitative methods.

A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, Johannesburg, In partial fulfilment of the requirements for the degree of Master of Management (Finance and Investment Management), 2016 / The relationship between real economic activity and stock market performance is one that has been extensively researched throughout many decades, across many economies. Many issues and debates have stemmed involving this relationship, with the major ones including those of the significance of the relationship, nature of the relationship as well as causality and direction of causality within the relationship. This research paper examines this relationship within the South African context, comparing the pre and post 2008 global financial crisis periods. Results both in support of and contrary to theory were found as real economic activity had an immediate postitive response to shocks imposed on the stock index, whilst the stock index had an immediate negative response to shocks imposed on real economic activity. Through the use of granger causality testing, no causality was found in either direction. Furthermore, no major differences were noted between the pre and post crisis periods. / GR2018

Dissertation submitted in partial fulfillment of the requirements for the degree of Masters of Management in Finance and Investments (MMFI) in the Graduate School of Business Administration University of the Witwatersrand 2017. / The Western Cape Fishing industry has been a subject of discussion in numerous papers, in which the thrust has been to seek ways of sustaining the significantly fluctuating business. Common risk factors have been identified and strategies for managing the fishing business in turbulent periods have been proposed over the years. A closer examination of previous literature as well as empirical evidence indicate that the business has less to do to control or minimize the impact of most of its external factors, which include the Government imposed Total Allowable Catch (TAC) limit, the variability in natural marine populations, environmental factors and fuel price oscillations. In the interest of curbing the variability component which is borne by the internal factors, this study brings on board a quantitative dimension to the evaluation of the four commonly cited internal factors, namely; Earnings Per Share (EPS), Margin of Safety (MOS), Free Cash-Flow (FCF) and the Net-Worth (NW) on volatility of the fishing business. The performance of five large JSE-listed fishing firms: Brimstone, Oceana, Premier Fishing, Sea Harvest and Irvin & Johnson, is investigated with the view of modelling and forecasting their volatilities. Initially, the comparison of volatility forecasts from symmetric and asymmetric GARCH-family models is employed. The results of competing models are tested using cross-validation of mean error measures and the Superior Predictive Ability (SPA) and Model Confidence Set (MCS) tests. Later, a Vector Autoregressive (VAR) model is applied to assess the impact of the four commonly cited internal factors on volatility. The research analysis results reveal a generally high volatility of the Western Cape fishing sector stocks. When univariate GARCH models are applied, the asymmetric GARCH-family models (EGARCH and GJR), with fat tails, appear dominant in the sets of competing models for all stocks, which highlights evidence of the leverage effect in the sector. However, GARCH (1,1), outperformed its counterparts in modelling and forecasting Irvin & Johnson (AVI) and Oceana (OCE) stocks. In the VAR modelling process, the Granger-causality tests indicate limited causal-relationship between EPS, MOS, FCF and the company Net-worth with the companies’ volatility measures. The variance decomposition of the 10-year ahead forecast of volatility indicates that volatility lag, free cash flow and networth have the largest contribution on volatility in the long-run, followed by margin of safety. In view of the above observations, the research discusses recommendations to the Western Cape fishing business to improve business returns and sustainability. / MT2017

Heavy rainfall and flooding often occur over South Africa. A high percentage of the heavy rainfall events occur over the eastern interior of South Africa and generally during the late summer (January to March) when the influence of tropical weather systems becomes dominant. Research into forecasting techniques best suited for tropical weather systems over southern Africa has been neglected since the early 1970's. The aim of this research was to develop a Model for the Identification of Tropical Weather Systems (MITS) as well as a Tropical Heavy Rainfall Identification System (THERIS) for operational use in the weather forecasting offices of Southern Africa. This study explains the dynamical properties of tropical weather systems and identifies those variables, which favour the development of heavy rainfall. Three case studies are presented to illustrate the dynamical properties of tropical weather systems. THERIS is tested and verified for historical heavy rainfall events over South Africa. The heavy rainfall events of February 2000 over the northern Provinces of South Africa are discussed and both THERIS and MITS are tested for operational functionality. Results indicate that MITS can be used to identify tropical weather systems and that THERIS determines areas of heavy rainfall. It is recommended that the two products be tested and used operationally. / Dissertation (MSc)--University of Pretoria, 2000. / Geography, Geoinformatics and Meteorology / unrestricted

Submitted in accordance with the requirements for the degree of Master of Management in the subject Finance and investments at the University of Witwatersrand 2017 / Although many studies have been done to determine the relationship between financial development and cost of equity capital in various markets, few have focused on the African emerging and frontier markets. This research therefore investigates the relationship between financial development and cost of equity capital in the African Emerging and Frontier Markets. Stock market development and banking sector development are both used as proxies for financial development in this study whilst cost of equity is determined using CAPM. The study is based on five emerging and frontier markets (Egypt, Kenya, Morocco, Nigeria and South Africa). The research finds that both measures of stock market development (stock market capitalisation to GDP ratio and stock market liquidity/turnover to GDP ratio) tend to reduce cost of equity in the African emerging and frontier markets. In a similar fashion, the banking sector development was also found to be negatively related to cost of equity / MT 2018

Script contains articles in Afrikaans and some text also in Afrikaans / Opportunities abound in the Armaments industry is South Africa and abroad. This is probably one of the main reasons why it has grown to almost astronomical amounts in va lu e . Simultaneously, the vast f igures in turnover and profits have attracted numerous competitors into the business. The next factor which has contributed most significantly to the increase in development and manufacture of armaments is of course the need of countries to defend themselves against aggressors. Political unrest , terrorism , border conflicts , war and invasions are the order of the day. All of these events require a show of arms, if not retaliation . In order to satisfy a need for strategic independence, even to a limited extent , countries have insisted on development and establishment of various categories of technologies. During the past fifty years there has been an explosion in the amount of information published in the technology sector. Some highly sophisticated technologies have become commonplace in most technical fields , including the armaments industry . As might be expected, the armaments industry is also greatly influenced by trends and change in the sector of economics, by social and cultural factors , and new legislation. It may rightfully be regarded as a highly volatile , complex and dynamic part of any economy. Under these circumstances the role of technology management in a country and in a business enterprise becomes more important, more difficult , and more essential. To ensure that a large organisation stays competitive, or becomes more competitive, the system of planning and control must be well integrated , kept up to date, and well/managed to fulfil its purpose. For the purpose of this script an investigation was undertaken into the corporate and business systems for technology management in a firm in the local engineering industry . The description covers planning and control theory, system models, innovation and technology management principles , and the theory of forecasting methods usually adapted for technology predictions , Evaluation of the practical systems which are in place and are being utilised , led to a few significant observations and conslusions. The investigation was by no means exhaustive, but was aimed at getting an overview of the corporate and business systems as they operate with in the stated strategic frameworks. It is concluded that technology planning and control systems are well-developed, highly integrated and applied in a top-down fashion . Not all aspects are conducted as efficiently as should be possible. Also, due to the dynamic nature of the industry, effectiveness can still improve for the company. Moves are afoot to meet new challenges and requirements and there is no doubt that the future will see great achievements. / Business Management / M.B.L.

Submitted to the Information Technology (IT) Department in conformity with the requirements for the degree of Doctor of Philosophy in Information Technology, Durban University of Technology. Durban, South Africa, 2016. / This doctoral research introduces an integration of satellite systems and new stratospheric platforms for weather observation, imaging and transfer of meteorological data to the ground infrastructures. Terrestrial configuration and satellite communication subsystems represent well-established technologies that have been involved in global satellite sensing and weather observation area for years. However, in recent times, a new alternative has emerged based on quasi-stationary aerial platforms located in the Stratosphere called High Altitude Platform (HAP) or Stratospheric Communication Platforms (SCP). The SCP systems seem to represent a dream come true for communication engineers since they preserve most of the advantages of both terrestrial and satellite communication systems. Today, SCP systems are able to help, in a more cost effective way, developments of space Earth sensing and weather observation and weather sensing and observation. This new system can provide a number of forms ranging from a low altitude tethered balloon to a high altitude (18 – 25 km) fuel-powered piloted aircraft, solar-powered unmanned airplanes and solar-powered airship.
