The arbitrage pricing theory in South Africa : an empirical study of the effect of pre-specified risk factors on share prices on the Johannesburg Stock Exchange.

Reese, Bernadine Kathleen. January 1993 (has links)
This study tests the Arbitrage Pricing Theory on the Johannesburg stock Exchange (JSE). Following the McElroy and Burmeister (1988) approach of pre-specifying a factor structure to be tested, a possible set of factors was selected on the basis of a priori theoretical and empirical evidence that they could affect share prices. All combinations of these factors were separately tested against mining and industrial shares listed on the JSE. Two sets of tests were performed, firstly, a multivariate nonlinear regression with cross-equation restrictions as a test of the APT model and secondly, a seemingly unrelated regression model. The APT test results for mining shares show that the model with gold price risk and residual market risk and the model with growth rate risk and residual market risk had the highest adjusted-R2 values. However these factors were not priced APT factors since they were not significantly different from zero. Two one-factor models yielded priced APT factors. These were the model including the gold price risk and another model with growth rate risk. Whilst these were both priced APT factors, the gold price risk model was better fitted. Four models were selected from the APT tests on industrial shares, on the basis of high adjusted-R2 values and factors which were significantly different from zero. They included the following risk factors: gold price risk and residual market risk; foreign exchange risk and residual market risk; inflation risk and residual market risk; default premium risk, gold price risk and residual market risk. The seemingly unrelated regression models had very similar adjusted-R2 values and indicated that the APT did not appear to explain the variation in share returns any better or worse than the seemingly unrelated regression model. The adjusted-R2 values for individual shares and the signs of the factor risk-premiums appear to be reasonable. The residual market risk factor was significantly different from zero for both the mining and industrial share samples, indicating that further work is required to identify the APT factors operating on the JSE. / Thesis (M.Com.)-University of Natal, Durban, 1993.

The effectiveness of land public passenger transport in the Johannesburg metropolitan area : a particular emphasis to bus passenger pubic transport customer service delivery excellence perspective.

Vilakazi, Ayanda Mendi. January 2003 (has links)
The South African Public Transport System plays an important role in the development of the economy in the country and in the region as a whole. Without an effective and efficient public transport system, the country's economic status would not improve. Classical macroeconomic theory suggests that transport is one of several key preconditions for economic growth. Transport is an industry in itself and employs many people. The Government has developed policies to regulate passenger transport in South Africa and in particular Johannesburg. There are national and provincial regulations that have been enacted by the national and provincial government. These are National Land Transport Transition Act, Gauteng Transport Infrastructure Act, Gauteng Public Passenger Transport Act and Moving South Africa Strategy. It was recognised in MSA that Metropolitan transport is clearly one of areas where crisis is looming. It is more and more difficult to move. Buses have lost clients to taxis. There seems to be consensus that the car is the only right choice for most citizens. The problem highlighted was that the public transport model is not working. Present urban transport strategy is based on short-term optimisation and it ignores the long-term effect of a poor urban transport-land mix. The secondary research seems to suggest that South African passenger bus transport in ineffective and inefficient. The research problem was subsequently stated to show that public transport in Johannesburg in ineffective because bus passenger transport model leads to dissatisfied passengers. Furthermore, the model is ineffective because of the past inequalities that led to poor transport infrastructure. This was found not to be true through primary research. The results showed that passengers were satisfied with the bus passenger transport in the Metropolitan areas of Johannesburg. Furthermore, it was found that indeed the poor infrastructure due to past inequalities has affected passenger transport service delivery. Overall, the passengers were satisfied with the bus transport model applied irrespective of where these passengers lived. It was then concluded that the bus passenger transport is effective. Operators have to be cautious of the fact that it is crucial to adopt a customer-focussed service approach as this will lead to satisfied passengers. The MSA strategy of the department of transport is heading in the right direction. It identifies the need for putting customers first. The strategy proposed a future core transport system that is high volume, high frequency corridors in which public transport will be a priority. Customer's need for improved access and short trip times will be met by having regular feeder services to the high volume corridors, user-friendly transfer facilities, short wait times due to high corridor frequencies and the possibility of differentiated services for customers with specific needs. The passengers transport strategy is moving from commuter-based modal transport to customer-based public transport there will be densification of transport corridors, optimal deployment of modes to meet customer service requirements and improving operators' level performance. / Thesis (M.B.A.)-University of Natal, Durban, 2003.

A cross-sectional study on sustainable solutions for commercial property in the City of Johannesburg for 2012

Crous, Jaco 12 1900 (has links)
ENGLISH ABSTRACT: This study determined the status, in 2012, of the implementation of Sustainable solutions (SS) to commercial buildings in the City of Johannesburg. The term “going green” was seen as an alternative approach to business, but demonstrated necessity in the property industry. As greenhouse gas emissions drive the rising average global temperature at an alarming rate, the business environment cannot only be aware of the impact that business industries have on the livelihood of the growing population, but need to act promptly to ensure sustainability. Environmental sustainability is an important topic in decision making for businesses in South Africa and this study grouped renewable energy (RE) and energy efficiency (EE) to create sustainable solutions as the main concept of environmental sustainability. Renewable energy refers to finding an energy source like the sun or wind, but the main focus is on the purpose of sustainability of the energy resource and the supply. Eskom obtains 97% of their electricity for South Africa from coal power plants, but the reality is that coal is a limited resource that will not be available indefinitely unlike renewable energy. Energy efficiency on the other hand focuses on reducing the energy requirements of commercial buildings. As this concept received sufficient attention in South Africa, the present study was conducted to obtain further information to drive energy efficient practices. With energy efficiency, making basic adjustments in the design of new buildings to use less electricity can greatly contribute to their longevity and reduce the overall running costs that in turn enhance the sustainability for organisations that own or manage properties. By gathering the principals for renewable energy from natural resources and implementing energy efficient practices, the concept of sustainable solutions was conceived. The implementation of sustainable solutions also increases the value of properties, fosters economic enhancement, fosters socioeconomic improvement and most importantly improves the environment by reducing carbon emissions.

Enkele organismiese veranderlikes in funksionele hemisferiese asimmetrie en die persepsie van emosie

Fourie, Jacqueline Carolina 23 April 2014 (has links)
M.A. (Psychology) / Research investigating the connection between Functional Hemispherical Asymmetry (FHA) and perception of affect in clinical as well as normal populations, is characterised by contradictory findings with regard to the role of the different hemispheres, especially as regards the perception of various valencies of emotions. Although a majority of studies indicates that the right hemisphere (RH) is superior in the perception of all valencies and emotions - positive as well as negative - there are numerous studies indicating a possible differential processing of positive and negative emotions by the hemispheres. Although various researchers try to lay the above contradictory findings and the general lack of consensus at the door of methodological problems/inequalities or error variances, the literature is increasingly pointing to the existence of evidently reliable individual differences between people as regards their hemispherical functioning. The problem investigated in the current study, is to determine the possible role of the organismic variables in FHA, i e variables seated in the individual who is making the observation. In this study, the focus is specifically on the role of sex and the temperament dimension of introversion-extraversion. The objectives of this study are to determine whether there are significant differences in the direction of these hemispherical differences, as well as the relative performance, of groups divided according to sex and temperament characteristics, and whether the relevant organismic variables offer a possible means of explaining the contradictions in research results on FHA and the perception of emotion. In this study, the measuring of FHA is operationalised in terms of the differential performance, measured in terms of accuracy and speed of observation (response latency) of the hemispheres in the perception of different valencies of emotional stimuli (positive versus negative, and approach versus avoidance emotions).. The subject population comprised a group of students selected in terms of sex and temperament (introversion-extraversion). Selection in terms of introversion-extraversion was done on the basis of subjects' performance in the Personality Questionnaire Form B (Schepers, 1991): persons falling in the lower and upper three stanines of the scale respectively were identified as introverts and extraverts. Only right-handed subjects with no history of brain injury were used for the study. Differential hemispherical performance in terms of response accuracy and latency was determined by means of the Divided Visual Field Technique (DVFT). Although the reliability data of this technique are generally not entirely satisfactory when measured in terms of psychometric test standards, an effort was made to enhance the reliability of the technique in this study by controlling specific stimulus and response variables (inter alia the exposure time and the use of both hands for a response) during the experimental design.

The role of intergroup conflict in school-based violence in the Johannesburg Central Education District Schools: towards a strategy for peace education implementation

Mkhomi, Moses Sipho January 2016 (has links)
School-Based Violence (SBV) is prevalent in South Africa and globally. SBV is one of the challenges that the South African education system is facing resulting in a new deep-rooted culture of unsafe and insecure schools. Teachers are expected to teach learners, who display antisocial behaviour. These learners swear, back chat, verbally and physically abuse and show total disrespect for teachers. The presence of such learners has turned schools into battle field. This violence is not exclusively directed to teachers, but learners are also the common victims of bullying in particular. This study therefore sought to investigate how intergroup violence impacts on the schoolbased violence. The concepts, Intergroup Conflict (IC) and gangs/gangsterism were used interchangeably to describe actions of individuals who take part in the social conflict, driven by competition, antagonism and aggression within the school context.

Street traders in Kerk Street, Johannesburg : aspirations and improvements, 2005-2009

Ruwana, Refiloe 12 December 2011 (has links)
M.A. / „Street trading is an activity which involves the selling of goods or the supply of services for a reward in a public road‟ (City of Johannesburg, 2009b: 5-7). This minor dissertation is an examination of the conditions and aspirations of street traders in Johannesburg‟s Central Business District (CBD), specifically Kerk Street. The underlying rationale is the fact that, while there is a small, but growing body of literature on street traders in South Africa, there is little on street trading in the Johannesburg CBD. Moreover, to the best of the researcher‟s knowledge, virtually none of this deals with the views and aspirations of the street traders themselves. This dissertation is based on the following research question: How did the conditions and aspirations of street traders in Kerk Street change between 2005 and 2009? Fieldwork was conducted in two phases: 2005/6 and 2009. The separation in periods of study, and the opportunity it provided for comparison, was unintended and largely as a consequence of work pressures. But it proved unexpectedly beneficial. The researcher‟s original concern was to discover how traders viewed their existence and detail of the developments that they would like to see. Conditions were clearly poor and tales of dissatisfaction were predominant in informal conversations and formal interviews. When the researcher returned to the field in 2009, the assumption was that conditions would be the same, allowing me simply to update my earlier assessment. However, this was not the case. Whilst much was familiar, some conditions had improved and the traders were relatively more positive about their situation and more optimistic about the future. It is clear that the Johannesburg City Council has intervened to introduce improved conditions, and this contributed to improved morale amongst traders. It is recommended that there be continued engagement between street traders, the City of Johannesburg, and official bodies, namely the Johannesburg Metro Police Department (JMPD), Central Johannesburg Partnership and Metro Trading Council. This will serve as inspiration for more traders to learn how to grow their businesses, to ensure that infrastructure around trading is further improved, and to increase adherence to and acceptance of relevant by-laws concerning the traders.

Proposals for the co-ordination of formal public passenger transport in the Johannesburg area

Wentzel, Frederick 28 August 2012 (has links)
M.Comm. / Formal public transport has an important function to fulfill, both in terms of service provision and also in the broader context of the economy. This is so because so many workers live in dispersed areas and are dependent on public transport to arrive at work. This point is especially valid with regard to the Soweto area, which is one of the most heavily populated areas in South Africa, providing a large workforce to South Africa's most important economic region — the Witwatersrand. The main theme of this study is that all "formal" passenger transport operators in the Soweto area need to be integrated and that structural co-ordination should take place. This includes service provision in terms of routes and schedules as well as the ticketing system. This study provides an overview of the activities of the "formal" operators in the Soweto area. The conclusion that can be drawn is that the current "formal" service leaves considerable scope for improvement. It is also clear from the reports that have been quoted in this study that the minimum levels of service are not being achieved. Hence, this study proposes new road-based routes and schedules aimed at improving the coordination of bus and rail transport in the Soweto and surrounding areas. This study also proposes an integrated ticketing system, which is aimed at forming the basis for effective co-ordination. The purpose of these proposals is to assist the yet-to-be-established Transport Authorities to make decisions that will guide the co-ordination process in the right direction. The study also investigates other aspects that influence the "formal" public transport system. These include Government Policy, national objectives, ticketing systems and coordination. These aspects, combined with current research and schedules will be used as the basis where-upon new suggestions are made. The study emphasises that the suggestions made will not necessarily improve cost effectiveness but are primarily aimed at improving upon the current service. The study suggests however, that any additional funding that may be needed will be a moderate amount with regard to macro-economic variables, and at the same time will improve the quality of life of the community and will help in achieving national transport objectives as envisaged by the Moving South Africa study project. It is also suggested in this study that the time for meaningless debate is over and that the time has arrived to implement practical solutions with regard to the formal public passenger transport system in South Africa.
