- Description: South African organisations are facing a new era of intense global competition. The modern business world is characterised by change and this change presents both challenges and opportunities. As a result, organisations have to become more responsive to change by continuous, rapid and cost-effective innovation through integrating the strengths of the entrepreneurial small firm, such as creativity, flexibility and innovativeness, with the market power and resources of the large firm. Due to the dynamic nature of the automotive industry, it is vital that South African organisations and management identify creativity and innovation as the main sources of sustainable competitive advantage. Sustained competitive advantage is derived from consistently satisfying customers’ wants and needs through innovation. An intrapreneurial philosophy is of key importance to an organisation’s corporate strategy, ensuring that entrepreneurial values are incorporated into the culture of the organisation. This study took place within an automotive component company operating in the Eastern Cape. Based on the theoretical findings of the literature study a questionnaire was developed and distributed to all employees of the company. The objective of the questionnaire was to measure the prevalence of intrapreneurship within the company and based on the findings of the literature study, recommendations on the structure, systems, culture and management styles of the organisation were made. Finally, a model was developed that identifies the importance of innovation, customer-solution centeredness and being market driven as core strategic values.

- Description: The private and social returns to education literature share the same conclusion: that education is beneficial for both the individual and society. However, the theoretical underpinnings are flawed as the literature does not account for the main feature that leads to the acquisition of education: the private demand for education. An understanding of the factors that motivate the individual to invest in education would lead to a deeper insight as to why both private and social returns to education exist, and would provide a clearer framework on which to base the government funding of education. This thesis provides a first attempt at filling this gap by introducing a method of estimating the returns to government investment in education, which is labelled the ‘labour market drop-out rate approach’. The approach focuses on the social return to education, not in terms of graduate earnings, but in terms of the interaction of the graduate with the economy. The approach introduces a measure of expertise utilisation, based on the premise that there is no social return to an individual acquiring education if he or she does not utilise the acquired knowledge base on entering the labour market. The approach is tested using the labour market for marine scientists in South Africa as a case study. In this case the private demand for education is found to be heavily influenced by the provision of student bursaries from the National Research Foundation, with a resulting estimate of the social return to a degree in marine science being a mere 20% to 25%. Owing to this, a new approach to government investment in marine science is introduced, that of graduate contribution schemes. Of broader significance is the ease of application of this approach, it may be adopted to analyse any funding programme in which a government may decide to invest. As such, the labour market drop-out rate provides an extension to the returns to education literature through its theoretical dealings of the private demand for education, as well as a practical tool which government agencies can use to evaluate the efficacy of any government funding of education.

- Description: There has been a shift in the South African education system from a purely grade-oriented system to that of a learner-centred outcome-based system of education which challenges higher educational institutions and their faculties to adjust their goals to this system. In South Africa there is evidence of poor academic performance at higher education institutions. Among other things, noncognitive factors may be important mediators of academic success. With the expansion of higher education and the increased emphasis on access, retention and life-long learning, it is a good reason to explore the nature of different learning styles (Healey & Jenkins, 2000). Learning styles and personality types has been identified as significant predictors of academic performance. The present study aimed to contribute to this body of research in general and to Kolb’s (1981) theory of experiential learning and his conceptualisation of learning styles in particular. The aims of the study were to explore and describe the learning styles of first year university students (Aim 1), to explore and describe the learning styles of first year university students per faculty (Aim 2), and to explore the relationship between learning styles and academic performance for students in the various faculties (Aim 3). The study used an explorative descriptive and correlational research method and was conducted within a quantitative framework. Participants were selected using a non-probability convenience sampling technique. The sample was comprised of 391 first year university students to whom Kolb’s Learning Style Indicator was administered as part of the Explore programme during orientation week. Descriptive statistics were used in order to explore and describe the learning style of the learners for the sample as a whole and per faculty. Data for the learning styles and academic performance categories were cross tabulated so as to comment on the relationship between learning styles and academic performance per faculty. Small cell sizes made it impossible to analyse the latter data statistically. Across the six faculties the Accommodator learning style was the most represented, followed by the Diverger learning style. No significant relationship was found between learning styles and academic performance. The implications of the findings for counselling and teaching students are highlighted and suggestions to expand the research through using larger samples are also made.

The life history patterns of the polychaete, Terebrasabella heterouncinata, a pest of cultured abalone

- Description: Terebrasabella heterouncinata is a small K-selected sabellid polychaete. It is a simultaneous hermaphrodite with a semi-continuous mode of reproduction, producing relatively few large eggs that are brooded within the parental burrow until the larvae emerge, to settle on the growing edge of the abalone shell. Despite its low fecundity, this worm has become problematic on abalone farms in South Africa. The present study was conducted to gain an understanding of the life history patterns of T. helerouncinata to determine how they contributed to the success of these worms under altered conditions. This study demonstrated that conditions prevalent on abalone farms were conducive to enhancing the reproductive success of this worm, and suggests that larger, more fecund worms may have been selected for in the decade that these worms have been present on the farms. Increased nutrient availability, and possibly the increased stability of the farm environment relative to its natural environment, has led to a 1.5-fold increase in the average size of the worms. Body size was found to be positively correlated with brood size, and this resulted in worms on farms brooding 3 to 4.5 times more offspring at a time than worms from wild abalone. The ability to increase the number of eggs produced at a time may have been limited by the fact that these worms have only two ovaries. Thus, the increase in fecundity may have been related primarily to the increase in the rate at which the eggs were laid by the worms on the farms, and the increase in the coelomic space available for the storage of these rapidly developing eggs. The ability to increase the rate at which oocytes develop may be related to the vitellogenic mechanisms employed by these worms. Vitellogenic oocytes are able to incorporate high molecular weight yolk precursors from the surrounding coelomic fluid through endocytotic activity. This may allow the oocytes to increase the rate at which they incorporate yolk material under conditions of nutrient enrichment. The increase in fecundity did not occur at the expense of offspring size and, presumably, quality. The increased reproductive output on the farms was compounded by a proportionate increase in the number of reproducing worms within the population. In addition, these worms are long-lived (worms from farmed abalone reached a maximum age of approximately 40 months) and exhibit negligible senescence. Thus, their reproductive output did not change significantly with an increase in age. Furthermore, the proportion of the reproductive worms did not decrease with an increase in age. Thus, within the age range tested, worms of all ages have the potential to make equal contributions to population growth. While diet and abalone stocking density could not be identified as having a significant effect on reproductive output and infestation rate under intensive culture conditions, it was demonstrated that in a naïve abalone population, the total intensity of infestation increased exponentially with time. This increase may be a consequence of an increase in fertilisation success. These worms continuously produce entaquasperm that are released into the water column. The sperm are collected by other individuals that then store the sperm in a single spermatheca. The ability to store sperm relieves individuals of a dependence on the synchronisation of spawning of eggs and sperm. As the population size and density increases, there could be more individuals releasing sperm into the water column, resulting in a continuous supply of sperm. The increased production of eggs would therefore not be constrained by a lack of sperm. The stored sperm are released into the brood chamber to fertilise eggs as they are laid, and this would probably increase the fertilisation success in the species. This study also provides evidence to suggest that reproduction in this worm has a seasonal component. Future studies should concentrate on measuring fertilisation success in greater detail, measuring the effect of season on reproduction, determining whether there are genetic differences between worms on farmed and wild abalone and determining whether wild worms have similar life-spans and age-related fecundity as worms on farms.

- Description: The sabellid, Terebrasabella heterouncinata, is a small (<5 mm) intratubular brooder that lives in burrows within the host s shell matrix. It is a semi-continuous breeder and despite producing small numbers of large eggs, infestation by this animal has reached epidemic proportions on local abalone farms. The present study compared the morphometrics and reproductive characteristics of worms from farmed and wild abalone, in the Walker Bay area of the south Western Cape Province of South Africa, to gain insights into why this animal has become so successful under aquaculture conditions. The farms designated farm A and farm B each had one on-farm site, and two wild sites, while farm C had two on-farm sites and two wild sites. The wild sites were natural abalone habitats located within 2.5 km of the farms. Our results conclusively showed that environmental conditions prevalent on the farms enhanced the reproductive success of these worms relative to that observed in its natural environment. At farms B and C, worms occurred in significantly higher densities at the on-farm sites than in the corresponding wild samples, but at farm A, density was equally low at the three sites. At all three farms, a greater proportion of the population was reproductively active in the on-farm samples than in the wild samples. Worms on farmed abalone had a higher instantaneous fecundity, brooded more clutches simultaneously and were larger than their conspecifics from the wild. There was a positive correlation between adult size and brood size and the number of clutches brooded simultaneously. Within the three on-farm sites there was a negative correlation between egg volume and brood size, indicating a trade-off between these traits. However, such a trade-off was not apparent between sites, with brood size being higher at the on-farm sites than at the wild sites, irrespective of egg size. This suggests that the stable nutrient-enriched environment on the farm led to an increase in fecundity without compromising the size (and implicitly the quality) of the eggs. Worm density did not have a significant effect on body size or any other reproductive traits at most sites, and the density of T. heterouncinata was unaffected by the density of other shell-infesting polychaetes. The results suggest that the farm environment has selected for larger, more fecund worms that breed rapidly with high recruitment success as a consequence of abundant nutrients, high host density, habitat stability and a possible lack of predation and interspecific competition.

- Description: Many network monitoring tools do not provide sufficiently in-depth and useful reports on network usage, particularly in the domain of application services data. The optimisation of network performance is only possible if the networks are monitored effectively. Techniques that identify patterns of network usage can assist in the successful monitoring of network performance. The main goal of this research was to propose a model to mine and visualise application services data in order to support effective network management. To demonstrate the effectiveness of the model, a prototype, called NetPatterns, was developed using data for the Integrated Tertiary Software (ITS) application service collected by a network monitoring tool on the NMMU South Campus network. Three data mining algorithms for application services data were identified for the proposed model. The data mining algorithms used are classification (decision tree), clustering (K-Means) and association (correlation). Classifying application services data serves to categorise combinations of network attributes to highlight areas of poor network performance. The clustering of network attributes serves to indicate sparse and dense regions within the application services data. Association indicates the existence of any interesting relationships between different network attributes. Three visualisation techniques were selected to visualise the results of the data mining algorithms. The visualisation techniques selected were the organisation chart, bubble chart and scatterplots. Colour and a variety of other visual cues are used to complement the selected visualisation techniques. The effectiveness and usefulness of NetPatterns was determined by means of user testing. The results of the evaluation clearly show that the participants were highly satisfied with the visualisation of network usage presented by NetPatterns. All participants successfully completed the prescribed tasks and indicated that NetPatterns is a useful tool for the analysis of network usage patterns.

- Description: Many network monitoring tools do not provide sufficiently in-depth and useful reports on network usage, particularly in the domain of application services data. The optimisation of network performance is only possible if the networks are monitored effectively. Techniques that identify patterns of network usage can assist in the successful monitoring of network performance. The main goal of this research was to propose a model to mine and visualise application services data in order to support effective network management. To demonstrate the effectiveness of the model, a prototype, called NetPatterns, was developed using data for the Integrated Tertiary Software (ITS) application service collected by a network monitoring tool on the NMMU South Campus network. Three data mining algorithms for application services data were identified for the proposed model. The data mining algorithms used are classification (decision tree), clustering (K-Means) and association (correlation). Classifying application services data serves to categorise combinations of network attributes to highlight areas of poor network performance. The clustering of network attributes serves to indicate sparse and dense regions within the application services data. Association indicates the existence of any interesting relationships between different network attributes. Three visualisation techniques were selected to visualise the results of the data mining algorithms. The visualisation techniques selected were the organisation chart, bubble chart and scatterplots. Colour and a variety of other visual cues are used to complement the selected visualisation techniques. The effectiveness and usefulness of NetPatterns was determined by means of user testing. The results of the evaluation clearly show that the participants were highly satisfied with the visualisation of network usage presented by NetPatterns. All participants successfully completed the prescribed tasks and indicated that NetPatterns is a useful tool for the analysis of network usage patterns.

- Description: I investigate the issue of whether or not one's holding a moral belief is sufficient to motivate one to act as that belief prescribes. I argue that rational persons who hold a moral belief that is also a 'self-referential belief' will form a desire to act as that belief prescribes and thereby be motivated to act on the moral belief. I argue for this claim by, firstly, showing that the demand that moral judgements must be intrinsically motivating, Internalism, should only apply to rational persons, that is, the link between moral judgement and motivation can be broken in cases of irrationality. Secondly, I argue against the Humean claim that one cannot rationally form a desire simply because one believes that one ought to have that desire. This claim requires an investigation into a variety of views of Practical Reason and an argument concluding that Practical Reason is broader in scope than the Instrumentalist or Humean allows. I undertake this task in chapter 2. Thirdly, I argue that believing that I ought to perform a certain action will give me an internal commitment to perform that action, insofar as I am rational. I argue that an internal commitment is a form of desire. Once I recognise that I have a moral belief and an internal commitment, I will be motivated to act as that belief and commitment prescribe. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: To date the SADC region has managed to develop a manufacturing base but this base is still small as evidenced by its low contribution to GDP. For example, only three out of the fourteen SADC countries, viz. Mauritius, South Africa and Swaziland, had over 20 percent of their GDP originating from the manufacturing sector throughout the 1990s. Also to note is that while the manufacturing sector is quite diversified, the sector is dominated by industrial processes which are more of resource and labour-intensive in nature than those processes of scale-intensive, differentiated and science based in nature. TIle trade performance of the manufacturing sector supports these observations and as such the region is heavily dependent on imports for scale-intensive, differentiated and science based commodities. However, despite the fact that the region tends to focus more on resource- and labour-intensive manufacturing activities, products from these manufacturing activities are still significant components of manufactured goods imports into the region. Also to note is that since resource- and labour-intensive industries dominate manufacturing activities; these are the areas in which investment opportunities abound. For example, agro-based manufacturing presents most of the investment opportunities, with food processing presenting the majority of the investment opportunities followed by garments and textiles production. Mineral processing also presents significant investment opportunities. The analyses of the nature of the manufacturing sector also show that in a few SADC countries, viz. Mauritius, South Africa and Zimbabwe; scale-intensive, differentiated and science based industries also form a significant component of the industrial base implying more technologically complex manufacturing sectors. Since high technology and technologically complex manufacturing activities are limited, investment opportunities in these manufacturing sub-sectors are also limited to just a few countries However, with the SADC ITA in place, opportunities could arise for these limited technology-related manufacturing facilities to expand or engage in import substitution production so as to meet the demands of the growing regional market. It is also important to note that, while the region may not have as competitive advantage in these industries as in the resource- and labour-intensive industries, there is a need for the region to selectively identify and target such industries for priority development, a lesson SADC could learn from the East Asian NIC's took in their industrialisation strategy. The study also shows that the manufacturing sector has been a priority sector for both domestic and foreign investors. This has implications for industrial development because a strong and dynamic manufacturing sector would be developed, forming a sound basis for industrialisation as well as being able to effectively link and support all the other sectors of the economy. FDI could help the region to fully utilise the labour-intensive industries and use them as a stepping-stone to higher levels of industrial development. This is a lesson to SADC from the experiences of the East Asian NICs where while industrialisation was initiated by labour-intensive manufacturing, the countries were able to move into capital-intensive manufacturing due to FDI as it enabled the establishment of the industrial bases, thus leading to a rise in the share of manufactured exports. FDI could also help to develop the resource-intensive industries further by promoting further processing of raw materials into products of more value, thus propelling industrialisation through a resource-led industrial development programme as the current resource-intensive industries become fully utilised. The raw materials which occur in great abundance in the region's primary sector would have a ready market in the manufacturing sector where they would serve as inputs to the production of high value products. The currently smaller industrial base for scale-intensive products, differentiated and science-based manufactured products would benefit from the improved technological capabilities and managerial skills that result from FDI. Therefore, by impacting positively on manufacturing activities of both low and high MVA, FDI would thus have a facilitating role in establishing a more solid industrial base, broadening the current manufacturing base, and improving installed capacity utilisation. The study also shows that investment in productive capacity in the form of machinery and equipment is of great importance in the sampled SADC countries. Investment towards the acquisition of this capital is very important as this is directly relevant towards improving productive capacity. FDI could thus play a facilitating role by augmenting the current domestic investment in machinery and equipment. While the manufacturing sector within the region is still small and the current utilisation of installed industrial capacity is low, there is potential for further industrial growth. The current process to usher in the SADC Free Trade Area would have a facilitating role through various ways: viz. increasing the market size and enabling easier access through the reduction of tariff and non-tariff barriers, promoting regional competitiveness, improved utilisation of regional corridors, increasing opportunities for utilising identified intra-industry trade potentials, and providing opportunities for increased regional cross-border investment. Apart from the SADC FTA, the USA African Growth and Opportunity Act (AGOA) and the Cotonou Agreement will also motivate the identification and utilisation of existing and new potentials within the manufacturing sector in SADC. In order to improve the current nature of industries in the region, there is also a need to design and implement appropriate industrial policies and strategies. Such policies should consider the region's trade policies and the recently launched Regional Indicative Strategic Development Plan (RISDP) so as to complement them. The industrial policies should also address issues relating to industrial investment, technology and local technological capabilities development, human resources development, the structure and nature of industry, the competitiveness of industries, as well as facilitating the complementarities between the agricultural and manufacturing sectors. To this end therefore, instead of relying solely on individual national industrial policies, SADC is in the process of formulating a regional industrial policy and strategies which seek to promote and support sustainable industrial growth across the region, thus facilitating industrial development.

- Description: The oxidative coupling of 2,6-di-t-butylphenol under mild reaction conditions is well documented and the subject of many patents. However, the coupling of other monoand di- substituted phenols is not as well documented and thus there is scope for further investigation for providing a convenient, environmentally friendly and economically viable method for the oxidative coupling of these phenols. In this study, the oxidative coupling of a variety of alkylated phenolic substrates, 2-tbutylphenol, 2,6-di-t-butylphenol, 2,4 -di-t-butylphenol and ,4-dimethylphenol, using a range of different oxidizing agents, were investigated by means of experimental and/or theoretical means. The dibutylated aromatics provided the highest selectivities to their respective coupled products, with results obtained with the dimethyl analogue being only satisfactory, and that for 2 -t-butylphenol being totally inefficient. PM3 Molecular orbital (MO) calculations were used to predict the possible modes of coupling for the substrates 2,6 -di-t-butylphenol and 2,4-di-t-butylphenol, and these results were then compared with those obtained experimentally in the laboratory. Preliminarily, the coupling of unsubstituted phenolics was also assessed by means of MO calculations. Much emphasis was placed on Ce(IV) as the oxidant, and the reaction conditions under which it was used and the results that were obtained have not been reported before and are therefore novel. The oxidation of 2,4-di-t-butylphenol using Ce(IV) in the presence of methanesulphonic acid was optimized to afford high yields and selectivities to the desired ortho C-ortho C coupled product under mild reaction conditions. Various reaction parameters were also investigated in this case, such as varying the MeSO3H concentration, the solvent, the reaction temperature, the reaction time, the substrate loading, the rate of oxidant addition and the substrate to oxidant ratio. Ce(IV) also gave a high selectivity to the para C-para C coupled product when IX using 2,6-di-t-butylphenol as the substrate. However, it was not as effective with 2,4- dimethylphenol, and even less so with 2-t-butylphenol. The oxidation reactions of 2-t-butylphenol and 2,4-dimethylphenol with various coupling agents were also investigated with the intention of obtaining high selectivities to the respective desired coupled products. In these studies, 2-t-butylphenol afforded a large number of products, irrespective of the oxidant used. The dimethyl analogue was more selective, but results were not optimal. It was clear that the number of substituents on the phenol ring, their nature and their position with regards to the hydroxyl moiety was of great importance and made a significant impact on the preferred coupling mode of the substrate. It was observed that steric effects also played a major role in the outcome of these reactions: 2,6-di-t-butylphenol never afforded any C-O coupled products whereas 2-t-butylphenol, 2,4-di-t-butylphenol and 2,4-dimethylphenol all appeared to undergo some C-O coupling. Finally, reaction mechanisms were provided for both the K3Fe(CN)6 and Ce(IV) work, these reacting in basic and acidic media, respectively. It was proposed that both of these mechanisms operate through the initial formation of the phenoxyl radical.

- Description: The transformation of education has been central to the programme of the first democratically elected government in Namibia, both because of the democratic demands for equality, equity and access, and as a means towards the wider transformation of Namibian community. The study provides a brief history of the pre- and post-independence education policy environment in Namibia with regard to how management and leadership of schools gave rise to opportunities for the development of democratic participation. Adopting an interpretive approach, the study examines several key stakeholders' perceptions of the impact of transformation initiatives on their leadership and management thinking and practice. The sample comprised four teachers, a principal, a director, a school board member, two learners and a hostel matron. The findings reveal that, in order to create a democratic school community, the stakeholders' role is largely a matter of opposing and transcending the contradictions, inadequacies and limitations inherent in the educational ideas, policies and practices caused by the previous Apartheid education system. There is a reasonable amount of success in the implementation process of democratic leadership and management of schools. The findings further highlight contradictory tendencies, in that the Ministry of Basic Education Sports and Culture established a uniform system of education but also entertained the principle of decentralised governance through the introduction of school based management practice incorporating the main stakeholders at local level. The data confirms a communication gap between stakeholders, lack of adequate education and training in participatory management and leadership for learners, parents, teachers and school boards, and insufficient support from the national and the regional authorities. The study concludes with some specific recommendations that might strengthen stakeholders' sense of their participation in democratic practices for longer-term cost effective implementation to occur. This is supported by the belief that education policy change only becomes a reality once understood, owned and appreciated at local level.

- Description: Worldwide millions of children are victims of neglect and physical and mental harm, including sexual abuse and exploitation. South Africa, however, is widely believed to have not only one of the highest incidences of rape in the world, but also one of the highest levels of Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) transmission. With research findings showing that HIV and other Sexually Transmitted Infections (STIs) are rapidly increasing globally, young people are, and continue to be, at the forefront of the AIDS pandemic. Therefore, it is suggested that prevention programmes should be aimed particularly at the young. Schools have specifically been recognized as the setting for preventative Life Skills Programmes, having the potential to reach billions of children worldwide. The aim of this study is to explore and describe the perceptions of grade eight and nine learners with regard to the Life Skills Programme that focuses on HIV/AIDS and STI's, rape and child abuse education in the Port Elizabeth region. In order to fulfil the above aim, a qualitative study was undertaken within an exploratory descriptive approach. A non-probability sample of four schools was selected. Focus groups, utilising an unstructured interview, were used to gather qualitative data on the learners' perceptions of the Life Skills Programme. The focus groups consisted of 10 - 12 grade eight and nine learners who were selected using simple random sampling. The data was thematically analysed using Tesch's approach. The major findings of the present study, based on the six general themes, include the following: 1. Most of the learners perceived the educators, as well as the teaching methods utilised by the educators, positively. 2. Although the learners perceived the presenters of the Life Skills Programme positively, it was suggested that teachers, health care professionals, family members and peers should be involved in presenting the Life Skills Programme. 3. Learners reported various levels of comfort discussing different topics presented in the Life Skills Programme. 4. Learners of all the schools perceived the Life Skills Programme to be very relevant. 5. Learners recommended that more children, especially children from deprived communities, should be included in the programme. In addition, learners felt that counselling services should be available in conjunction with the Life Skills Programme. 6. Differences were noted in completing the first and the second questionnaire. Learners reported that they felt more comfortable completing the second questionnaire. They perceived the interviewing process positively.

Learners of all the schools perceived the Life Skills Programme to be very relevant. 5. Learners recommended that more children, especially children from deprived communities, should be included in the programme. In addition, learners felt that counselling services should be available in conjunction with the Life Skills Programme. 6. Differences were noted in completing the first and the second questionnaire. Learners reported that they felt more comfortable completing the second questionnaire. They perceived the interviewing process positively.

- Description: Research has shown that Attention Deficit Hyperactivity Disorder (ADHD) is one of the commonest neurodevelopmental disorders which has a negative impact on a child. However, to date limited research has been conducted on learners, and specifically those learners with ADHD, within a National Education stream. Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.

- Description: [From the introduction]: Guy Butler, born in Cradock on 21 January 1918, was a serious poet. Nearly a third of his poems are about death or loss, and many of the rest about parting failure, or difficult self-denial. His poetry is generally thoughtful and responsible to a deep religious vision. Of the ninety poems published between 1939 and 1979 the finest are those written between 1943 and 1963, from “Syrian Spring” to “Sweetwater.” The best poems cluster like moons round “On First Seeing Florence,” which is a major poem seldom given its rightful attention.

- Description: With the seemingly infinite existence of complex emergencies and the overwhelming presence of humanitarian organizations responding to such crises, it is essential that the assumptions, precepts, and actions of humanitarian organizations be critically examined and understood. The aim of this thesis is to explore differing traditions within humanitarian thought: neutrality and solidarity. In the process, this thesis will determine whether it is possible to maintain clear ideologies in the context of a complex emergency and whether the existence of different humanitarian ideologies results in a dichotomy or polarization of humanitarian action. This study is of great import as it delves into the contemporary literature claiming that humanitarianism is currently in a state of crisis – the unsustainability of competing humanitarian ideologies operating together in a complex emergency. Primary documents from both the International Committee of the Red Cross (ICRC) and Médecins Sans Frontières (MSF) regarding their operations in the 1994 Rwandan complex emergency were examined in order to provide a foundation for the theoretical investigation. Although the ICRC and MSF occupy seemingly polarized positions in the neutrality – solidarity debate, the investigation into their humanitarian activities during the 1994 genocide and the resulting refugee crisis reflected the difficulties of providing relief based upon humanitarian ideals. Due to the complex realities of the 1994 Rwandan crisis, the ideological notions dividing the ICRC and MSF were overshadowed by the simple humanitarian desire to aid those in need.

- Description: The aim of this thesis was to explore the experience of “self” within the clinical context of adult survivors of childhood trauma. Childhood trauma in this study referred to a range of childhood experiences of emotional and physical assault, including encounters with various kinds of abuse and neglect. The focus was on the experience of a sense of disintegration and dislocation, associated to aspects of self being in conflict. This was explored from theoretical perspectives of Jungian analytic psychology, as well as art therapy.Answers were sought to the questions of how claywork, as a form of art therapy, may facilitate the integration of the self and contribute to the development of a healing dialogue with feared and hated aspects of self. Grounded in Jungian theory, integration of the self was conceptualised as a movement towards “differentiating wholeness”. The study took the form of a phenomenological-hermeneutic case study. One participant’s experience of making and discussing a clay sculpture in a therapeutic setting according to Edwards’ method, was analysed thematically. It was concluded that the potential of claywork in therapy to facilitate the integration of the self is related to three aspects. Firstly, claywork in therapy may promote a concrete personification of feared and hated aspects of self, which may enable the maker to view these aspects from a distance, and learn to understand them in a new way. Secondly, claywork in therapy may facilitate the safe ‘unearthing’ of repressed feelings as well as hidden aspects of the personality. Thirdly, claywork’s potential to mediate symbolic functioning was shown to be an important aspect of the integration process. These findings confirmed and extended existing theory regarding the usefulness of claywork in psychotherapy with adult survivors of childhood trauma. Brief recommendations for future research were provided.

- Description: South Africa is an arid country and its growing population is putting freshwater resources under increasing pressure. Natural salinization of freshwater systems is being exacerbated by anthropogenic influences. The National Water Act (No. 36 of 1998) stipulates the need for an ecological Reserve, that quantity and quality of freshwater needed to protect freshwater ecosystems while allowing sustainable use of freshwater resources. Water guidelines do exist in the form of the South African Water Quality Guidelines (DWAF, 1996) and more recently, Jooste and Rossouw (2002) compiled benchmark values for water quality variables marking the boundaries between ecological health classes in the 4-category classification system. Predominantly international toxicity data were used to compile the guidelines and the benchmark values. In addition, there is a paucity of chronic toxicity data nationally and internationally. This thesis showed that it is statistically possible to derive protective chronic endpoints for salinity from acute toxicity data through extrapolation. The Acute to Chronic Ratio (ACR), Two-Step Linear Regression (LRA) and Multi-Factor Probit Analysis (MPA) extrapolation methods were investigated to derive chronic toxicity data from acute toxicity data. The authors of LRA and MPA recommend associating a time independent LCx value in the range of LC₀¸₀₁ to LC₁₀ with a Predicted No Effect Concentration (PNOEC). In addition to published methods, this thesis studied the possibility of equating a time independent LC₅₀ value and subjected to a safety factor of 5 (LRA LC₅₀/5), to the PNOEC. Extrapolated chronic toxicity data where the toxicants are NaCl and Na₂SO₄ were derived for indigenous South African macroinvertebrates. NaCl and Na₂SO₄ are salts associated with salinisation in South Africa. In addition, a chronic salinity toxicity test protocol for an indigenous South African aquatic macroinvertebrate was designed and chronic toxicity test were performed using NaCl and Na₂SO₄ as toxicants. The experimental chronic toxicity data produced were used to validate results from the acute to chronic extrapolation methods. Extrapolated chronic toxicity data were inputted into Species Sensitivity Distribution curves, and concentrations that were predicted to protect 95 % of species (PC95) were compared to the sub-lethality benchmarks proposed by Jooste and Rossouw (2002) for NaCl and Na₂SO₄. This study concluded that the LRA LC₅₀/5 extrapolation method is the most protective and accurate and proposed that LRA replace the ACR method in future guideline development for inorganic salts.
