Fruit flies (Tephritidae) can enter and establish in new territories due to the movement of fruit from one area to another through trade or tourism, which can negatively impact on fruit production and market access. An invader fruit fly species (Bactrocera invadens) has established on the African continent and has spread throughout sub-Saharan Africa. This newly described polyphagous fruit fly species is a successful invader species which continues to distribute and establish in new habitats. The introduction and establishment of B. invadens in South Africa may have serious market access consequences with regard to fruit exports due to its absence in the territories of many trading partners. The Musina area was considered as the study area as it is the first entry point from Zimbabwe. The national highway (N1) which runs through the area is a major route from several B. invadens infested countries in the Southern Africa region. A species initiated pest risk assessment was conveyed to determine the risk potential of this pest. The pest risk assessment (PRA) identified several pathways with a high risk to the Musina area, that B. invadens can follow. A detection survey was carried out to determine the status of B. invadens in the Musina area as support to the PRA. The detection survey continued over three years and by the second year B. invadens was detected for the first time in the study area. The detection survey was followed by a delimiting survey and the pest was eradicated in the area. After several months of no detection, it was however detected again in the area. Risk management options were suggested for regulatory control as an outcome of the pest risk assessment. These measures can be utilised by the National Plant Protection Organisation of South Africa for the commercial importation of host material of B. invadens, control of fruit imported by travellers, informal traders and national control in the event of pest incursions in the area. Corrective actions as well as quarantine actions should be implemented in an integrated approach in the affected areas. / Thesis (Master of Environmental Sciences)--North-West University, Potchefstroom Campus, 2013.

It is widely believed among South African agricultural market participants that the United States' corn price, as represented by the Chicago Board of Trade-listed corn contract, is causal to the price of white and yellow maize traded on the South African Futures Exchange. Although a strong correlation exists between these markets, the corn contract is far from causal to the South African maize price, as indicated by Auret and Schmitt (2008). Similarly, South African market participants believe that volatility generated in the United States corn market spills over to the South African market. Given the perceived volatility spill-over from the corn market to the maize market, market participants might inadvertently include a higher volatility component in an option price in the South African maize market than is necessary. This study sought to quantify the amount of volatility spill-over to the South African white and yellow maize market from the United States corn contract. This task was accomplished by applying an Exponential Generalised Auto Regressive Conditional Heteroscedasticity model, within an aggregate shock framework, to the data. The findings indicated that the volatility spill-over from the United States corn market to the South African maize market is not statistically significant. This result suggests that volatility in the South African market is locally driven; hence, it should not be necessary for a South African listed option contract to carry an international volatility component in its price. It was also found that the returns data of the South African maize market is asymmetrically skewed, indicating that bad news will have a greater effect on the price of maize compared with good news. / Thesis (MCom (Risk Management))--North-West University, Potchefstroom Campus, 2013.

People make a company. Their expertise and talents, efficiency and job performance determine the company‘s profitability and growth. The long-term retention of employees is of the utmost importance, as these employees have a wealth of knowledge about the company, its industry and the products or services being sold. Businesses have created plans to retain employees for a maximum period of time. These ideas include cash bonuses, phantom share schemes, and providing the employee with shares in the business. This study will look at such ideas in general, and specifically investigate the different ways of providing employees with shares in the business. There are different ways of providing the employee with shares in a business. This can include loans (including interest-free loans) to the employee from the employer, loans to the employee from a financial institution, employee share ownership plans, company share option plans and providing the employee with shares in the business through an employee share trust. Each of these methods attracts certain taxes such as income tax, capital gains tax and secondary tax on companies or dividend tax. The aim of this study is to use a case study approach, critically analysing an anonymous company providing its employees with shares in the company through an employee share trust, and will specifically investigate the different tax consequences of each transaction taking place in the trust AFRIKAANS : Werknemers is 'n maatskappy se belangrikste bate. 'n Maatskappy se winsgewendheid en groei word deur sy werknemers se kennis, doeltreffendheid en werksprestasie bepaal. Dit is vir 'n maatskappy van kritieke belang om sy werknemers vir so lank as moontlik te behou, aangesien hierdie werknemers oor kosbare kennis besit rakende die maatskappy, die bedryf waarin die maatskappy besigheid doen en die produkte of dienste wat die maatskappy bemark. Talle maatskappy het skemas bewerkstellig om hulle werknemers vir so lank as moontlik te behou. Dit behels onder andere kontantbonusse, fiktiewe aandeleskemas en die verkryging van aandele in die maatskappy deur die werknemer. Hierdie studie ondersoek sodanige skemas in die algemeen, en fokus spesifiek op werknemers wat aandele in 'n maatskappy bekom. Werknemers kan aandele in die maatskappy op verskillende wyses bekom. Hierdie wyses sluit in lenings (insluitend rentevrye lenings) van die maatskappy aan die werknemer, lenings aan die werknemer van 'n finansiële instelling, aandeleskemas, opsies om aandele in 'n maatskappy te koop, en die verskaffing van aandele aan die werknemer deur 'n werknemer-aandeletrust. Elkeen van hierdie opsies het spesifieke belastinggevolge, insluitend inkomstebelasting, kapitaalwinsbelasting, en sekondêre belasting op maatskappye of dividendbelasting. Die doel van hierdie studie is om 'n spesifieke gevallestudie van 'n annonieme maatskappye te ontleed, waar die maatskappy aandele aan sy werknemers deur 'n werknemer-aandeletrust verskaf het, en sal in detail na die belastinggevolge van elke aksie in die trust te kyk.
