- 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: For integration between application-systems in a global context, interoperability needs to be established on a global level; global interoperability, in turn, is based on a global common application-interface. This is achieved through resolving differences in, inter alia, protocol profiles, among participants in the global network. ebXML is used as the point of departure. A messaging framework, which is based on existing Web technology and standards, is proposed. Certain security and Web service standards are examined to determine specific parameters for an interoperable secure messaging environment. A security based framework comprising a predefined message format and architecture is investigated for a secure interoperable global electronic marketspace.

- Description: This paper deals with an analysis of the discursive accounts of Eastern Cape white commercial farmers on the subject of Democracy. Drawing on the theoretical perspectives of Social Constructionism and Discourse Analysis – which view individuals’ accounts of their realities as produced and informed by their particular social and historical context – the paper seeks to provide an analysis of the content of, and rhetorical strategies within the participants’ accounts and explanations. Such accounts of the social, historical and political circumstances in which Eastern Cape commercial farmers find themselves are thought to provide valuable insights into the manner in which the process of democratisation has been received by members of the agricultural sector. Data collection was conducted via brief, audio taped, semi-structured interviews. The participants were all white men and women, living in a commercial farming region of the Eastern Cape Province. Responses to the interviews were subjected to the Discourse Analytical procedure advanced by Ian Parker. Analyses reveal that participants are critical of the notion of democracy; utilize specific rhetorical and argumentation strategies; make use of notions and techniques of ‘Othering’; and subscribe to a colonial / patriarchal ideology which attempts to idealize pre-democratic South Africa. These findings illustrate what is in many ways still an ongoing political and ideological struggle in the rural regions of the country.

- Description: Alzheimer's disease is a progressive neurodegenerative disorder, in which there is a marked decline in neurotransmitters, especially those of the cholinergic pathways. One of the approaches to the symptomatic treatment of Alzheimer's disease is the inhibition of the breakdown of the neurotransmitter acetylcholine, using an acetylcholinesterase inhibitor. One such drug tested, is the organophosphate, metrifonate. Any drug used for the treatment of neurodegenerative disorders should preferably not induce further neurological damage. Thus, in the present study, we investigated whether or not metrifonate is neuroprotective. The in vivo and in vitro effect of this drug on free radicals generation shows that metrifonate increases the level ofthese reactive species. Lipid peroxidation induced using quinolinic acid (QA) and iron (II) and show that metrifonate increased the peroxidative damage induced by using quinolinic acid. Metrifonate is also able to induce lipid peroxidation both in vivo and in vitro. This was reduced in vitro in the presence of melatonin. Using iron (II), in vi/ro, there was no significant difference in the level of lipid peroxidation in the presence of this drug. An investigation of the activity of the mitochondrial electron transport chain and complex I of the electron transport chain in the presence of metrifonate revealed that metrifonate reduces the activity of the electron transport chain at the level of complex I. The activity of the mitochondrial electron transport chain was restored in the presence of melatonin. Pineal organ culture showed that metrifonate does not increase melatonin production. Histological and apoptosis studies show that tissue necrosis and apoptosis respectively, occur in the presence of this agent, which is reduced in the presence of melatonin. Metal binding studies were performed USing ultraviolet spectroscopy, and electrochemical analysis to examine the interaction of metrifonate with iron (II) and iron (III). No shift in the peak was observed in the ultraviolet spectrum when iron (ll) was added to metrifonate. Electrochemical studies show that there may be a very weak or no ligand formed between the metal and drug. This study shows that while drugs such as metrifonate may be beneficial in restoring cognitive function in Alzheimer's disease, it could also have the potential to enhance neurodegeneration, thus worsening the condition, in the long term. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Most government owned telecommunication operators across the world have to deal with a number of regulatory, technology and service challenges, as the industry is liberalised in co-ordinance with worldwide trends. Telkom SA will be facing a number of strategic challenges that will test its ability to survive as a telecommunications company over the next number of years. To remain competitive, Telkom must develop strategies to assure survival in a competitive environment. To assure the long-term survival of Telkom SA when moving into a competitive environment, the organisation must build a sustainable competitive advantage. In the face of increasingly fierce competition, the adoption of collaborative alliances between firms is becoming more and more common and the adoption of a world-class supply chain will be an ideal scenario for Telkom SA. A worldclass supply chain goes beyond the scope of the internal operations of an organisation, therefore the material distribution process was chosen for this study, which involved the internal operations in the organisation. The study included the availability of material up to the transportation of the material to the staging areas. The aim of this research was to identify the inefficiencies of the material distribution process of the Southern Region of Telkom SA to become worldclass. A quantitative technique was used to identify the inefficiencies. It was found that the availability and transportation of material were the inefficient categories, preventing the customer to receive the product or service on time. Communication, inaccurate forecasting and inefficient transportation of material were some of the reasons for not delivering material on time. Some of the recommendations included developing a model that could overcome the current inefficiencies in transportation, improving the communication channels, training and the development of employees at all levels.

- Description: The re-introduction of cheetah onto small reserves in the Eastern Cape Province has created the opportunity to study this species in an environment (Valley Bushveld) in which it has not previously been studied and which is quite different from the less wooded habitats in which previous studies have occurred. Thus the aim of this study is to add to the growing number of studies of cheetah in more wooded habitats and to contribute a better understanding of the level of specialization or adaptability in space use, habitat selection, diet and hunting behaviour that the cheetah possesses. The research was conducted on Kwandwe Private Game Reserve from February 2003 to August 2004. Direct observations, scat analysis and continuous observations were used to avoid bias towards large sized prey found when only using direct observations to study diet. The cheetah killed 15 species and four of the five most important prey species (kudu, springbok, grey duiker and bushbuck) were hunted according to their abundance on the reserve, while impala, the fifth most important prey species, was avoided (i.e. preference index less than one) by the cheetah. The cheetah’s main prey was medium sized ungulates, although the three male coalition killed larger prey than females and females with cubs. The daily food intake per cheetah per day was calculated to range from 5.3kg/cheetah/day for the coalition to 8kg/cheetah/day for a solitary female. Home range areas ranged from 11.1 km² for female cheetah with cubs in a den to 65.6 km² for single female cheetah and core areas ranged from 6 km² for the three male coalition to 26.5 km² for independent cubs. Habitat selection by cheetah on Kwandwe varied between the social groups depending on their susceptibility to predation by lions, their need for cover and need for water, and was similar to what has been previously reported. The home range of the coalition incorporated the most open vegetation type (karroid shrubland) with surrounding denser vegetation, while females occupied areas of denser vegetation. Activity patterns and hunting behaviour varied between different cheetah social groups with female cheetah being more active during day light hours compared to males which made 38% of their kills after dark. The average chase distances for the various cheetah groups varied considerably, and the chase distance for successful hunts was longer than for unsuccessful for all groups except single female cheetah. The percentage of kills’ kleptoparasitised on Kwandwe was very low compared to other studies possibly due to the low density of direct competitors, which in turn lead to longer mean kill retention times. These results suggest that cheetah are more adaptable than previously thought and this adaptability may have important implications for their conservation.

- Description: As argued by authors like Franzen on whose work the greater part of the introduction, the main problem and sub-problem has been based, the objective of this study was to establish the extent to which the performance evaluation system currently in use at the subject Institution conforms to the benchmark performance management systems as espoused in literature. Further, the objective was to establish the differences and commonalities between the performance management systems practiced in the corporate sector and current practice at the subject Institution. Best practice was thus lifted to form part of the recommendation of this study. A questionaire was designed based on the guidelines in the literature study in order to determine how the subject Institution conducts its performance appraisal and how this relates to the four general purposes of performance management mentioned in the study.

The study concludes with a statement of current practice at the subject Institution, and outlines the extent of conformance to benchmark practice on performance management systems. Recommendations are made based on best practice and direction is given to future research into contemporary practices with the express aim of enhancing quality in higher education applying the quality-related procedures of industry and commerce, where quality is crucial to success (Winch, 1996: 9-13).

- Description: As argued by authors like Franzen on whose work the greater part of the introduction, the main problem and sub-problem has been based, the objective of this study was to establish the extent to which the performance evaluation system currently in use at the subject Institution conforms to the benchmark performance management systems as espoused in literature. Further, the objective was to establish the differences and commonalities between the performance management systems practiced in the corporate sector and current practice at the subject Institution. Best practice was thus lifted to form part of the recommendation of this study. A questionaire was designed based on the guidelines in the literature study in order to determine how the subject Institution conducts its performance appraisal and how this relates to the four general purposes of performance management mentioned in the study. The respondents' opinion obtained from the questionaire were compared with the guidelines in literature and clustered around the four identifiable general purposes of performance management. The study concludes with a statement of current practice at the subject Institution, and outlines the extent of conformance to benchmark practice on performance management systems. Recommendations are made based on best practice and direction is given to future research into contemporary practices with the express aim of enhancing quality in higher education applying the quality-related procedures of industry and commerce, where quality is crucial to success (Winch, 1996: 9-13).

- Description: Management’s response to shareholders’ return on investment as a priority occurs in an increasingly dynamic environment. Accompanying these activities is the need to realign responsibilities and to allocate scarce resources effectively. This is done in order to ensure that companies achieve global competitiveness and increase shareholders’ return on investment. Against this backdrop, local industry needs to find new methods or strategies in order to achieve world-class competitiveness, and to be able to access foreign investment. One way to achieve these goals is through Value Based Management (VBM). The objective of this study is to evaluate the strategic intent of Multinational Entities in applying VBM to increase shareholders’ return on investment. Based on the study, certain factors are critical to ensure the success of VBM. A postal survey to managers in the motor manufacturing and component manufacturing companies was conducted to check the managers’ familiarity with VBM, and their scope, and usage of VBM; and, based on the finding, to evaluate the impact of VBM on companies’ results. The empirical finding was compared with a literature review, and the following findings were made: There is a strong understanding and application of the VBM principle on the part of local entities with Foreign Direct Investment (FDI); Departmental performance is critical to an entity’s overall performance; Based on the study, 23 per cent of the respondents use Economic Value Added (EVA) as an internal reporting measure, and an average of 19 per cent use other metrics; A total of 89 per cent of respondents indicated that they strongly agree with the use of incentives for motivation. The above-mentioned points were covered by means of 4-M framework ― that is: Measurement, Management, Motivation, and Mindset.

- Description: The human resource is constantly cited as an organisation's greatest asset. In a rapidly changing technological environment this is most applicable to the Information Technology (IT) function. Organisations are experiencing IT human resource problems such as low satisfaction, early plateauing, high turnover, burnout, limited advancement potential, nominal corporate commitment, supervisory aversion, poor organisational culture, and exceptional compensation. These problems are directly related to the IT professional's career. There is a lack of information and awareness surrounding IT careers to deal effectively with these problems. The research aims to create increased awareness of IT careers and the inherent problems through the development of a career management model. The research aims to identify the factors that influence IT careers, provide career management with a means to measure compatibility of the factors, and suggest solutions to incompatibility. The solving of this problem will be of mutual benefit to both organisations and individuals as they seek to better manage IT careers. After reviewing research literature relating to career anchors, IT job types, IT skills portfolios, and career dynamics a model for Effective IT Career Management (EITCM) has been constructed. The model represents the dynamic interactions between individual, organisational, and dependent factors. The model examines the compatibility of these interacting factors by measuring the levels of relevant career variables. The model suggests appropriate career management techniques to increase the compatibility of the interacting factors. An empirical study was designed and launched online to provide data that would confirm the seven Critical Success Factors (CSF) relating to the proposed model. The responses from the members of the Computer Society of South Africa (CSSA) allowed the seven hypotheses derived from the CSFs to be tested. The results of the empirical study were positive but required modification to five of the CSFs before they could be confirmed. The EITCM model was modified to reflect the improved CSFs. An awareness of career influencing factors combined with active career management is advantageous to both IT professionals and their organisations.

- Description: The syntheses, spectral and electrochemical characterization of new family electropolymerizable pyrrole, thiophene and mercaptopyrimidin substituted metallophthalocyanine (MPc) complexes are described. Tetraamino substituted chromium and manganese phthalocyanine complexes were also synthesized and characterized. The spectral and electrochemical results are comparable to literature reports. The complexes formed stable films when deposited on electrode surfaces. The MPc films were formed by electropolymerization, drop-dry method and self-assembling. Nickel hydroxide-like electrodes were formed by electrotransformation of nickel-tetra-4- (pyrrol-1-yl)phenoxy phthalocyanine polymer films to the corresponding PcNi-O-NiPc modified electrodes in alkaline solution. The thiophene, mercaptopyrimidine functionalized MPcs and amino group containing complexes formed good self-assembled monolayers (SAMs) on gold electrode. The electrode modification processes were reproducible. The conductivities of the electrode were dependent on the surface concentrations of the complexes as a function of electropolymerization scan numbers. The electrodes showed good catalytic responses toward L-cysteine, nitrite, nitric oxide (NO), glycine, phenol and its derivative and oxygen. The results also suggest that the presence of thio groups on the ring substituents lowers the oxidation potential of Lcysteine more compared to literature values. The stability of the amperometric responses toward the various analytes is used to diagnose the applicability of the materials for electroanalytical purposes. The limits of detection for L-cysteine, nitrite, NO and glycine were in the range of ~10⁻⁷ to 10⁻⁵ mol dm⁻³.

- Description: Effective environmental education goes beyond raising environmental awareness and developing positive environmental values, to the encouragement of personal responsibility and action in response to contextual environmental issues in particular. The whole school approach has been advocated as the best approach to environmental education, based on the assumption that the values and attitudes espoused in the classroom need to be reflected in the day-to-day school practice. By practising what they teach, schools reinforce values with action. In contrast, inconsistencies between the formal and non-formal curriculum may lead young people to question the integrity of their teachers or condition them to accept such inconsistencies as cultural and social norms, which in turn may lead to apathy about the environment. Adjustments to the ethos of a school to foreground the environment, both within the curriculum , the management of the school and the behaviour of teachers, pupils and support staff, is not a straightforward undertaking. Institutional factors influence the change process in schools and each school presents a unique context. It is, therefore, difficult to develop a general strategy for the evolution of an environmental ethos. This case study narrates an attempt to implement a change towards an improved environmental focus in a school, and focuses on developing an understanding of how available resources can assist this process while engaging with complexity of change.

- Description: Hydrological variability involving rainfall and streamflows in southern Africa have been often studied separately or have used cumulative rainfall and streamflow indices. The main objective of this study was to investigate spatio-temporal variations of rainfall, their influences on streamflows and their relationships with climatic variations with emphasis on indices that characterise the hydrological extremes, floods and droughts. It was found that 60-70% of the time when it rains, daily rainfalls are below their long-term averages and daily amounts below 10 mm are the most frequent in southern Africa. Spatially, climatologies of rainfall sub-divided the southern African subcontinent into the dry western/southwestern part and the “humid” eastern and northern part. The daily amounts below 20 mm contribute significantly to annual rainfall amounts in the dry part while all types of daily rainfall exceeding 1 mm have comparable contributions in the humid part. The climatologies indicated the highest likelihood of experiencing intense daily events during the core of the wet seasons with the highest frequencies in central Mozambique and the southern highlands of Tanzania. Interannual variations of rainfall indicated that significant changes had occurred between the late-1940s and early-1980s, particularly in the 1970s. The changes in rainfall were more evident in the number of daily rainfall events than in rainfall amounts, led generally to increasing early summer and decreased late summer rainfall. It was also found that intra-seasonal dry day sequences were an important parameter in the definition of a rainy season’s onset and end in southern Africa apart from rainfall amounts. Interannual variations of the rainy season characteristics (onset, end, duration) followed the variations of rainfall amounts and number of events. The duration of the rainy season was affected by the onset (Tanzania), onset or end (tropical southern Africa - southwestern highlands of Tanzania, Zambia, northern Zimbabwe and central Mozambique) and end (the remaing part of southern Africa). Flow duration curves (FDCs) identified three types of rivers (ephemeral, seasonal and perennial) in southern Africa with ephemeral rivers found mainly in the dry western part of the region. Seasonal streamflow patterns followed those of rainfall while interannual streamflow variations indicated significant changes of mean flows with little evidences of high and low flow regime changes except in Namibia and some parts of northern Zimbabwe. It was, however, not possible to provide strong links between the identified changes in streamflows and those in rainfall. Regarding the influences of climate variability on hydrological variability in southern Africa, rainfall variations in southern Africa were found to be influenced strongly by ENSO and SST in the tropical Indian ocean and moderately by SST in the south Madagascar basin. The influence of ENSO was consistent for all types of daily rainfall and peaks for the light and moderate (< 20 mm) events in the southern part and for the intense events in the northern part. SST in the tropical Indian ocean influence the light and moderate events while SST close to the region influence the heavy events. However, the relationships experienced significant changes in the mid-1950s and in the 1970s. The former changes led to improved associations while the latter deteriorated or reversed the relationships. The influences of climatic variables on streamflows and rainy season characteristics were inferred from the rainfall-streamflow and rainfall-climatic variables relationships.

Yet ten years into the new dispensation nothing significant has been done to alter a situation in which the majority of children are obliged to access their basic education largely through the medium of a second or even a third language — English. In contravention of both the intentions and the specific provisions of numerous legislative measures and policy statements, Government has made no serious or effective attempt to promote the use of any language other than English in South African schools nor to encourage language practices most conducive to the cognitive development and academic success of millions of non-English speaking pupils. To make matters worse, most of the children who enter the school system with very little knowledge of English and are expected to make an abrupt transition to that language as a medium of instruction after a totally inadequate three years are from impoverished households and communities still suffering the gravest effects of the discrimination and oppression of apartheid. They are often underprepared and seriously disadvantaged by their background circumstances when they enter the culturally strange and intimidating western-style education system. To heap on top of these disadvantages the burden of language practices in the classroom that hinder rather than facilitate their access to education is indefensible. When Macdonald asks, “ Are our children still swimming up the waterfall?” (Macdonald 2002: 111) she is not exaggerating. In these circumstances and if ineffective language teaching and inadequate use of the mother tongue as a medium of instruction can be shown to bar effective access to basic education of an acceptable standard, there are far more serious and far-reaching implications in terms of human rights than just the right to choice of language medium. Linguistic research into medium of instruction has tended to be isolated from evaluative legal approaches to minority language rights, children’s rights, education rights or other fundamental human rights. Insufficient attention has been given to the interrelationship between the various rights and the importance of local conditions and circumstances in any assessment of their relative weight and enforceability. Human rights cannot be seen out of context, and theory from various disciplines, such as politics, economics and linguistics may be invaluable in forming a fresh perspective on the right to mother tongue education and, indeed, to basic education in general. The principle of non-discrimination in education is generally recognised, to be sure, as is the importance of ensuring access to and quality of education (Strydom 1992/93:139), but the dependence of these factors on the most appropriate medium of instruction within the education system does not merit much attention in the literature. The right to basic education tends to be seen as separate from any possible right to choice of medium of instruction and the latter often merely as a question of convenience or preference, at best a qualified right (Oosthuizen and Rossouw 2001: 666), dependent on feasibility, numbers and available finance (Motata and Lemmer 2002: 111). In fact, the case for regarding the right to mother tongue education as a strong positive right in many contexts and countries does not appear yet to have been made. This study is theoretical in nature and constitutes an attempt to fill this gap by examining the findings and views of experts from various disciplines within the framework of current thinking on human rights issues. The development of a coherent framework within which to view the right to mother tongue education and government obligations in connection therewith might be of some value to policy makers in their efforts to plan improvements within the education system. The synthesis and possibly, to a limited extent, the development of theory from the relevant disciplines will be undertaken by means of a survey of the relevant literature, an analysis of not only local but also international legislation and policy documents and the weighing and balancing of conflicting evidence and contrasting viewpoints. Sources and contributions in each area will be discussed under the headings outlined in Chapter 3. First, however, I should like to provide an overview of the educational, political and economic context in which mother tongue education must be considered.
