According to the Sectional Titles Act 95 of 1986, levies are assigned according to the size of a unit, in other words a unit’s participation quota. These levies are used to finance a complex’s insurance, common property electricity and water, lift maintenance, audit fees, management agent fees, salaries and wages, security, swimming pool expenses and general building maintenance. According to the Traditional Costing System, indirect costs are allocated based on a single cost actual expenses over a year are dissected. A regression and correlation analysis was done on the relationship between costs, participation quota and levies. The contribution of the study is that it empirically determines the behaviour of cost items in order to allocate indirect costs more accurately. Consequently, this will result in improved reasonability and will eliminate the cross-subsidisation of units. The objectives were reached as follows: The first objective was reached when it was proved through empirical studies that the Sectional Title is not fair when it states that the allocation of levies must be according to floor space. The second objective was reached when both participation quota and units per complex were identified as cost drivers for each cost item. The third objective was reached by allocating the levy on a 50 percent base according to units and a 50 percent base according to the total area. This could be refined by each complex according to the unique need of the complex. driver. However, various indirect costs are not necessarily subject to this single cost driver. In practice, it has been proven that high volume products are proportionally taxed with indirect costs when compared to low volume products. In many complexes, owners with larger units are of the opinion that their larger units are subsidising those owners with smaller units. In contrast to the traditional costing system, activity-based costing recognises that indirect costs can also be assigned by use of multiple cost drivers. Since these multiple cost drivers – which affect the way costs are assigned – can be identified, indirect costs are assigned more accurately. This study investigates the current method of cost allocation, whereby costs are assigned via participation quota, and makes suggestions on how these costs can be assigned on a more accurate and fair basis in practice. The goal of this study is to challenge the reasonability of the Sectional Titles Act. The objectives of the dissertation are firstly, to determine the cost behaviour of various cost items and whether the participation quota is a fair cost driver for determining the levies that are to be paid; secondly, it investigates alternative cost drivers that will be more applicable to certain cost items; thirdly, to suggest a cost formula to replace the current cost method, that being the allocation of indirect costs via participation quota. Empirical methods have been used in the research. The empirical research was performed using data obtained from ANGOR Property Specialists (Pty) Ltd’s database.

This study examines human capital constraints in the South African economy, and the austerity these constraints have on firms in the country. The first part of the study identifies the main human capital constraints facing South Africa, and explains how these constraints influence an economy. An inadequately educated workforce along with restrictive labour regulations makes out the central components of these constraints. The second part explores all the relevant constraints individually, and determines the cause of their existence. The final part of this study consists of a firm level analysis that describes human capital constraints experienced by firms in South Africa. Regression analysis examines the determinants of increased output per worker in manufacturing firms. These determinants also indicate the cause of growth in output per worker. Human capital aspects such as education, labour regulation, compensation and competition are all shown to have a considerable influence on output per worker. Principal Component Analysis (PCA) on the explanatory variables achieved similar results. For this analysis, latent variables that incorporated education, training, region and Sector Education Training Authority (SETA) support and effectiveness explained the highest percentage of the total variance. However, this study found no evidence to suggest that human capital development initiatives like training programmes and SETA support have a positive relationship with increased levels of productivity. / Thesis (M.Com.

In South Africa various financial institutions and independent vendors have developed residential property valuation models to estimate the current value of historically traded properties. A natural extension to these models has been to develop historical property price indices. In this dissertation, three of the four approaches to developing property price indices will be examined. Through back–testing and other statistical methods, the most accurate and robust approach will be determined. The four major approaches available are the mean valuation per suburb, the median valuation per suburb, the repeat sales approach and hedonic regression. The mean valuation per suburb approach can be biased because of outliers in property prices. However, outliers in property prices will not influence the median valuation per suburb approach, but in cases where property values in a suburb have a skewed distribution, the valuation amount could be distorted. Neither of the above mentioned shortcomings influences the repeat sales or the hedonic regression approach. To follow the hedonic regression approach, the characteristics of the property need to be known. In South Africa, however, the available property data lacks detailed characteristics of traded properties. This dissertation will therefore focus on the first three methods. The repeat sales approach measures the growth in property prices by applying a generalized linear model to properties that have traded more than once. This approach is only possible if there is a representative amount of repeat sales able to fit a model. The focus of this project will be on the repeat sales approach, but all three the approaches discussed will be analysed to prove that the repeat sales approach is the most accurate in developing a property price index for properties in South Africa. / Thesis (M.Sc.

Rekenaars kan ’n nuttige rol speel in vertaling. Twee benaderings is vertaalgeheuestelsels en masjienvertaalstelsels. By hierdie twee tegnologieë word ’n vertaalgeheue gebruik—’n tweetalige versameling vorige vertalings. Hierdie proefskrif bied metodes aan om die kwaliteit van ’n vertaalgeheue te verbeter. ’n Masjienleerbenadering word gevolg om foutiewe inskrywings in ’n vertaalgeheue te identifiseer. ’n Verskeidenheid leerkenmerke in drie kategorieë word aangebied: kenmerke wat verband hou met tekslengte, kenmerke wat deur kwaliteittoetsers soos vertaaltoetsers, ’n speltoetser en ’n grammatikatoetser bereken word, asook statistiese kenmerke wat met behulp van eksterne data bereken word. Die evaluasie van vertaalgeheuestelsels is nog nie gestandaardiseer nie. In hierdie proefskrif word ’n verskeidenheid probleme met bestaande evaluasiemetodes uitgewys, en ’n verbeterde evaluasiemetode word ontwikkel. Deur die foutiewe inskrywings uit ’n vertaalgeheue te verwyder, is ’n kleiner, skoner vertaalgeheue beskikbaar vir toepassings. Eksperimente dui aan dat so ’n vertaalgeheue beter prestasie behaal in ’n vertaalgeheuestelsel. As ondersteunende bewys vir die waarde van ’n skoner vertaalgeheue word ’n verbetering ook aangedui by die opleiding van ’n masjienvertaalstelsel. / Computers can play a useful role in translation. Two approaches are translation memory systems and machine translation systems. With these two technologies a translation memory is used— a bilingual collection of previous translations. This thesis presents methods to improve the quality of a translation memory. A machine learning approach is followed to identify incorrect entries in a translation memory. A variety of learning features in three categories are presented: features associated with text length, features calculated by quality checkers such as translation checkers, a spell checker and a grammar checker, as well as statistical features computed with the help of external data. The evaluation of translation memory systems is not yet standardised. This thesis points out a number of problems with existing evaluation methods, and an improved evaluation method is developed. By removing the incorrect entries in a translation memory, a smaller, cleaner translation memory is available to applications. Experiments demonstrate that such a translation memory results in better performance in a translation memory system. As supporting evidence for the value of a cleaner translation memory, an improvement is also achieved in training a machine translation system. / School of Computing / Ph. D. (Rekenaarwetenskap)
