- Description: Psychobiographers study the lives of extraordinary, prominent, and enigmatic individuals. Psychobiographical research advances our insight into the uniqueness and complexity of the human personality and therefore makes a substantial contribution towards one of the major objectives of the field of psychology. Purposive sampling was employed to select Charlize Theron as the subject of this psychobiographical study. As the only South African who has won an Oscar, Theron is an exceptional individual who demonstrates tenacity and a will to succeed despite significant traumatic events in her childhood. The case study data was organised and analysed according to the general analytic approach developed by Huberman and Miles (2002) and one of Alexander’s (1990) strategies, namely questioning the data. Erikson’s psychosocial theory (1950, 1963, 1995) was selected to guide this study because it recognises the impact of socio-cultural influences on developmental processes and provides a comprehensive, staged framework for studying Theron’s personality development. This study contributes to the development of psychobiographical research in South Africa.

The effects of labour law on small firms in South Africa : perceptions of employers in the hospitality sector in Pretoria, Gauteng
- Authors: MacNeill, Jessica Dawn

- Description: The South African government has attempted to find a balance of interests between the employer and the employee by the introduction of the Labour Relations Act in 1995 and the Basic Conditions of Employment Act in 1997. It is critical to the health of the South African economy that these labour laws do not impact small businesses to the extent that the Gross Domestic Product of the country is negatively affected. There are conflicting reports as to how these labour laws affect small businesses. It is therefore important for government to be able to understand, define and measure the impact of its labour laws on small businesses, in order for it to strategise corrective measures, which may include reconsidering the application of the legislative directive, regulated flexibility, if required. The study was limited in the sense that it was solely based on evidence collected from employers. An interpretivist approach was applied as a research methodology to data collected through in-depth interviews. The main findings of the empirical analysis demonstrate that labour legislation does not heavily impact small firms. It was thus determined that extensive measures were not needed with regard to correcting the framework of regulated flexibility.

A predictive biogeography of selected alien plant invaders in South Africa

- Description: Five techniques were used to predict the potential biogeography of the four alien plant species, Acacia longifolia, Acacia mearnsii, Opuntia ficus-indica and Solanum sisymbrifolium. Prediction was based on five environmental factors, median annual rainfall, co-efficient of variation for rainfall, mean monthly maximum temperature for January, mean monthly minimum temperature for July and elevation. A geographical information system was used to manage the data and produce the predictive maps. The models were constructed with presence and absence data and then validated by means of an independent data set and chisquared tests. Of the five models used, three (the range, principal components analysis and discriminant function analysis) were linear while the other two (artificial neural networks and fuzzy logic) were non-linear. The two non-linear techniques were chosen as a plant's response to its environment is commonly assumed to be non-linear. However, these two techniques did not offer significant advantages over the linear methods. The principal components analysis was particularly useful in ascertaining the variables that were important in determining the distribution of each species. Artifacts on the predictive maps were also proved useful for this purpose. The techniques that produced the most statistically accurate validation results were the artificial neural networks (77% correct median prediction rate) and the discriminant function analysis (71% correct median prediction rate) while the techniques that performed the worst were the range and the fuzzy classification. The artificial neural network, discriminant function analysis and principal component analysis techniques all show great potential as predictive distribution models.

An investigation of reactions directed towards the synthesis of 2-methyl-2-(methylthio)propanal oxime
- Authors: Whittaker, Ruth Eleanor
- Date: 1995
- Subjects: Pesticides -- Synthesis , Insecticides , Aldicarb -- Synthesis
- Language: English
- Type: Thesis , Masters , MSc
- Identifier: vital:4322 , http://hdl.handle.net/10962/d1004980 , Pesticides -- Synthesis , Insecticides , Aldicarb -- Synthesis
- Description: The processes leading to the formation of 2-methyl-2-(methylthio)propanal oxime, known industrially as aldicarb oxime, have been studied. The three stages of the synthesis, viz., chlorination, thiomethylation and oximation have been thoroughly investigated, with the aim of optimising the yield and purity of aldicarb oxime. Attention has been focused on the chlorination step, and the effects of altering various conditions have been determined; the reaction has been carried out in the absence and presence of heat, solvent and buffer, and the extent of chlorine addition has also been varied. These studies have led to some improvement in the yield for this step. Several simple and inexpensive methods for purifying contaminated batches of aldicarb oxime have also been examined. Possible aldicarb oxime contaminants, identified by GLC and GC-MS analysis, have been synthesised for use as chromatographic and spectroscopic standards, and confirmation of the presence of a number of these contaminants has been achieved. Aldehyde trimers have been found to be the primary contaminants present in aldicarb oxime and the thermal stability of these trimers, their corresponding monomers and aldicarb oxime itself has been studied using variable temperature ¹H NMR spectroscopy. Novel pyridine derivatives, with potential as aldicarb analogues, have been synthesised and characterised using spectroscopic methods.

A phenomenological explication of the male alcoholic's experience of existence with mother and father
- Authors: Singer, Stanley
- Date: 1984

- Description: Much is written, especially in psychodynamically oriented literature, about the unduly close dependency relationship male alcoholics have with their mothers. Whilst not disputing this it became apparent to myself when working with them that they also expressed strong attachments to their fathers who were described as absent or punitive. The literature goes on to theorize that a repressed homosexual element is often at work in the male alcoholic. Not much more of substance is said about the father other than he may be absent or punitive - even less is mentioned of the male alcoholic's experience with his father. It appears that this relationship has remained largely unexplored as a result of an uncritical imposition of theory, especially psychodynamic, upon the complex phenomenon of alcoholism. These theories generally posit the mother's influence over all problems in living be they neuroses, psychoses or alcoholism. It is possible that a dialogue exists between mother, father and alcoholic son which is more extensive and complex than that currently described in the literature, with father playing a greater role than previously believed.
