- Description: This study is a critical analysis of child labour and human resource development in Uganda. The study was undertaken because of the growing concern about child-labour practices in African countries, Uganda being an example. The incidence of child labour and the form that it takes are driven by supply-anddemand factors countrywide, but also by the sheer need of children to survive. Child labour is considered to be a fundamental child development problem. Children are involved in a number of child-labour practices such as prostitution in the commercial and tourism sex industry, forced begging on the streets, and forced soldiering. They may be used as camel jockeys, domestic servants, farm labourers/herders, mine labourers, produce porters, roadside sellers/street vendors, sweetshop-industry labourers, cooks and porters for rebels. The persistent exploitation of children involved in hazardous work and conditions has become overwhelming in Uganda. Poverty as one of the major causes for the growing numbers of child labourers in the agricultural sector in Uganda has caused a number of children to engage in child-labour activities to earn extra income for household survival. Many children have opted for partial attendance in school, eventually dropping out. Parents have also frequently influenced children to work on family farms, thus contributing to the children dropping out of school. Child-labour practices have become entrenched in the social and moral fabric of Ugandan society, and for this reason, research endeavours to uncover ways and methods to reverse this situation. The main objectives of this research were to establish the impact of poverty on child labour, to assess the effect of the social and cultural setup on child labour, to find out the impact of child-labour legislation enforcement, to determine the 5 influence of the HIV and AIDS pandemic on child labour, to establish the effect of the educational system and technological advancement on child labour, to establish the level of awareness of human rights in the community, and to establish the impact of human rights activists on the prevention of child labour. The study was undertaken in Masindi District in Budongo Sub County, in three parishes, Nyabyeya, Nyantonzi and Kasongoire. The respondents used for the study included child labourers, their parents, farmers, and community leaders. The method used to get to the sample was purposive sampling. Data was collected using questionnaires for written answers and a tape recorder for oral answers. Both primary and secondary data was collected, verified, edited, checked, coded, analysed, and then exported to Excel and SPSS. Collecting the data was a challenging exercise for the researcher. Experiences were varied, in the hospitality and willingness of respondents to learn more about child issues. Although respondents were willing to participate in the data collection exercise, social and cultural values did not permit all of them to share their views with the researcher. To collect data from respondents, the researcher had to ensure that remuneration was in place at the end of the exercise. The respondents filled out the questionnaires only after learning of the availability of a reward for every questionnaire answered. More setbacks were the need to travel long distances, and enduring the poor infrastructure, poor sanitation, and epidemic outbreaks, some of which diluted the quality of data collected. During group interviews, most parents were not entirely truthful about involving their children in child-labour activities. Although most respondents had an idea of what child labour is, their ignorance levels on the topic prevented them from stopping their children from working. The major findings of the research were that the cultural, social and economic setup of the community in the study area favoured child labour, although the child-labour legislation is against using children as labourers. Various ethnicities 6 in the study area considered a person between the ages of 5 and 12 years to be a child, yet the Constitution of Uganda dictates the age of childhood to be below 18 years. This causes conflict in the definition of who a child is. Although parents were aware of the Universal Primary Education (UPE) regulation penalties for not taking children to school, they still permitted children to engage in child-labour activities, and little has been done by government to curb the culprits. Awareness of the Sub Counties and Credit Co-operatives (SACCOs) and their implementation has not helped to reduce poverty in the area studied, resulting in an increased school dropout rate among school-going-age children, as well as more child-labour activities. The major conclusion of the study was that little has been done to increase the awareness levels of the teachers, parents and their children about child labour and its legislation, their knowledge of and involvement in micro-finance institutions in the community, and the availability of vocational training institutions. Little has therefore been done to reduce child-labour activities, improve the economic status of the community, and improve their human resource skills. The major recommendations of the research to the study are that culture should not override the Constitution as far as the definition of age limit is concerned. The government should carry out stakeholder analyses, and implement a life-skills and sensitisation programme in order to improve child participation in the Universal Primary Education (UPE) programme. Government should ensure that the society is given information about basic accounting, project planning and management skills, in order to be effectively involved in the economic programmes of SACCOs.

- Description: The nasal turbinates of ungulates are complex bony scrolls within the nasal cavity. These intricate bony plates, covered by moist epithelium, provide a large surface area that facilitates a countercurrent exchange of both water and heat between turbinal lining and respired air. Given their functional importance, maxilloturbinate size and structural dimensions may vary among species of different body sizes, activity levels and from different habitats, and may also serve as a predictor of the ability of the species to cope with high temperatures or limiting water resources. This is the first study to measure nasal turbinate surface area in ungulates using high-resolution computed tomography (CT) scanning. Heads of eleven South African bovid species and one European bovid species were successfully scanned and surface area measurements made using stereological techniques. These species included Cape grysbok, springbuck, bushbuck, blesbok, impala, mountain reedbuck, fallow deer, kudu, nyala, gemsbok and blue wildebeest; and represent species of different body sizes, from a range of habitats and with different water dependencies and predator avoidance strategies. The total maxilloturbinate surface area increased with body size for all study species. The surface areas of the nasal turbinates varied rostrocaudally, with the highest surface area occurring approximately midway along the length of the maxilloturbinate bones. The Cape grysbok stood out as having a nasal turbinate surface area of 12.77 cm2/kg, which was lower than the observed trend, the reason for this not being clear from these data. Phylogenetic independent analyses showed that log body mass and water dependence had a significant effect on nasal turbinate surface area, with habitat, distributional range and anti-predator behaviour having no effect. Subsequent phylogenetic species comparisons showed that structural variations in nasal turbinate surface area were phylogeny based due to the close genetic relatedness of the study species, and not associated with any environmental factors. The environmentally linked results for water dependency need further investigation in future studies of larger sample sizes and a broader range of species. Changes in climatic conditions may impact on a species‟ activity patterns, with individuals being forced to make behavioural modifications rather than physiological or anatomical adjustments. However, there is no clear evidence to indicate large differences in nasal turbinate surface area in relation to water dependence. This subsequently rules out the use of nasal turbinate surface area as a predictor to which and how ungulate species will respond to increasing global temperatures.

- Description: Competitiveness is crucial to achieving solid future national economics. A nation’s competitiveness reflects the extent to which it is able to provide increased prosperity to its citizens. Competitiveness can be defined to include the level of productivity of a country. This, in turn, sets the sustainability level of prosperity that can be achieved by an economy (Porter & Schwab, 2008). President Mbeki stated in the 2004 State of the Nation Address that “(South Africa) must continue to focus on the growth, development, and modernisation of the First Economy” (National Research Foundation, n.d.). The National Research Foundation (n.d.) claims that knowledge, innovation, and productivity, as well as optimal use of resources in the enterprise, are key to a competitive, sustainable growing economy. Firms involved in lean manufacturing do so to improve overall company performance in terms of productivity, efficiency, profitability and reducing costs. More than 90 per cent of these firms claim to be successful in achieving such goals. There is a clear association between the use of lean manufacturing and achieving higher productivity (Lucey, 2008a). Against this research and the claims made by the National Research Foundation it may be stated that lean manufacturing results will impact positively on an economy’s growth. AB Company will be evaluated in terms of the readiness and future sustainability of its lean transformation for the purposes of this study. It is anticipated that the results of this study will contribute toward reducing the risk of failure associated with a major lean transformation in the business.

- Description: South Africa currently has one of the highest levels of crime in the world. The high prevalence of violence in South African culture has led to the increased exposure to violence of individuals of all ages. The South African Police Service annual report for 2008/2009 reported 48 732 crimes ranging from murder, attempted murder to sexual offences and common assault against children under the age of 18 years. In addition, young people between the ages from 12 to 22 are generally victimized at twice the adult rate and even higher for violent crimes. It is the belief of various theorists that exposure to violence can alter one’s cognitive, affective, and behavioral processes- the three core components that are essential to moral development. The role that exposure to violence has on the development of aggressive behavior has been thoroughly researched; however the implications that this exposure has on the moral development of adolescents remains vague. This study explored and described the relationship between exposure to violence and moral development amongst adolescent learners. A quantitative exploratory descriptive research design was employed and the participants were selected by means of non-probability, convenience sampling. The sample consisted of 53 participants at a coeducational high school in the Nelson Mandela Metropole. The demographic data of the participants was gathered through the administration of a biographical questionnaire. The participants’ exposure to violence was explored by using the Harvard Trauma Questionnaire- South African Adaptation (HTQ-SAA), while their moral development was assessed by means of the Moral Judgment Test (MJT). The data was analysed using descriptive statistics and both the Pearson’s correlation coefficient and Chi square test was computed to draw inferences regarding the relationship between exposure to violence and moral development. The results of the study revealed that all of the participants were exposed to violence directly or indirectly on one or more occasion; however the frequency with which the participants were exposed to violence was lower than expected. The results of the MJT further indicated very low to low moral judgement competence scores for the majority of the sample. No significant correlation or association was found between the two constructs.

- Description: This dissertation analyses the South African Rental Housing Act 50 of 1999 ("the RHA") with the aim of determining whether the RHA sufficiently protects the landlords‘ rights and interests as opposed to those of tenants (which it does indeed safeguard). Due to the current saturation of rental property in South Africa, landlords are no longer in an advantageous a position as before. In fact, the RHA was introduced to redress the imbalance caused by discrimination against tenants. However, times have changed. The researcher submits that the RHA needs to be re-examined in light perception of the landlord as a consumer. Having regard to both common and foreign law, the researcher identified the following four fundamental legal and practical rights on the part of the landlord: the right to freely contract; the right to safeguard financial interests; the right to safeguard proprietary interests; and the right to evict a defaulting tenant. The research reveals that the RHA does not give adequate recognition to these fundamental legal rights, and accordingly does not sufficiently protect the landlord as a consumer. In total nineteen recommendations how the RHA can adequately recognize and protect the landlord‘s interests are made.

NMMU alumni as non-donors : why NMMU alumni do not become donors to the institution

- Description: This project investigates why alumni do not become donors to the Nelson Mandela Metropolitan University. Interviews with non-donors created the opportunity for an in depth qualitative examination of the motivating process that led these non-donors to abstain from giving. This study used the Van Slyke and Brooks (Van Slyke & Brooks, 2005) model of alumni giving and the Schervish (Schervish, The spiritual horizon of philianthropy: New directors for money and motives, 2000) supply side theory of philanthropy, which has been successfully applied in similar studies (Wastyn, 2008), to provide the conceptual framework. This framework maintains that donors and non-donors differ in that the manner in which they socially construct their university experience in creating their own realities. This constructed reality becomes the filter through which non-donors pass requests for financial support (whether direct or indirect) from the institution. The study revealed that at NMMU factors including generic donor behaviour among alumni, the status of current non-donors as being mostly past donors to their respective constituent institution, attitudes toward the institutional reputation (or aspects thereof) of the NMMU, identified obstacles to engagement, pervasive negative attitudes to institutional giving and alumni support for commercialised but not tiered giving activities, can play a major role in restructuring the manner in which non-donor alumni should be approached. The study demonstrates the need to include non-donors in research that explores alumni giving to the university. It confirms the distinct impact of the abnormally distributed demographic characteristics of this university and confirms that examining the impact of these characteristics and experiences cannot be effectively done by simply relying on one or two simple variables. Being a management project, 13 (thirteen) distinct categories of management recommendations are made, ranging from strategy development, through accounting and budgeting practice, to proposing specific revenue generating initiatives. The study concludes with the view that Alumni can and should be able to make a notable contribution to the revenue of the university and in so doing, contribute to the sustainability of the pro-social transformation process of the Nelson Mandela Metropolitan University.

- Description: Psychobiography is a qualitative approach to exploring and understanding the life story of an individual through the lens of psychological theory. The application of theory is typically done on the finished lives of well-known or enigmatic people. This study explores and describes the psychological development across the lifespan of Ernesto “Che” Guevara, by applying the Individual Psychology of Alfred Adler. Che Guevara was an Argentine Marxist revolutionary, physician, author, guerrilla leader, and major figure of the Cuban Revolution. Since his death, his image has become a symbol for revolution within popular culture. Extensive data has been examined in this work to ensure an accurate description of Guevara’s life. Alexander’s model of identifying salient themes was used to analyze the data within a conceptual framework derived from the theory. Guevara was fiercely loyal to his cause, at the expense of the lives of many Cuban citizens as well as his own family, whom he spent little time with. He justified this with his firmly held belief that the end justified the means and that he was always fighting for the greater good. He quite literally dedicated his life to his cause, which is the reason that he has become a modern day symbol for revolution. It is however unfortunate that this came at such a great personal expense.

- Description: Psychobiography is a qualitative approach to exploring and understanding the life story of an individual through the lens of psychological theory. The application of theory is typically done on the finished lives of well-known or enigmatic people.

- Description: White rhino populations did not occur historically in the Eastern Cape, South Africa (Skead 2007). They have, however, been introduced into a number of reserves within the Eastern Cape for reasons such as conservation, ecotourism and hunting. Based on the literature on the species, it was hypothesized that white rhinoceros would have been introduced in grass-rich habitats, as they are bulk grazers. White rhinoceros populations were further assessed in terms of population establishment by outlining their distribution and performance since introductions and this was done by extracting intercalving intervals from the literature of native populations and comparing such to the Eastern Cape intercalving intervals, extracted from data obtained from landowners. Finally, the diet of white rhinoceros was quantified, in order to identify plant species potentially at risk from white rhino herbivory using Shamwari Private Game Reserve as a study site. The distribution of white rhino in the Eastern Cape varies in terms of habitat and vegetation types. The majority (62%) of white rhino are located in grass-poor habitats and are primarily there for ecotourism purposes with only a small percentage kept for conservation purposes in the state reserves. Limited data for intercalving intervals of the white rhino in Eastern Cape are comparable to those of populations in the natural range. The ex situ conservation of white rhino in the Eastern Cape proved to be a success as population numbers have increased markedly since the first survey was conducted (Buijs 1999). The diet section of this study showed that white rhino are highly selective grazers even in a grass-limiting habitat which is dominated by browse. Twenty-five principal dietary items were identified in their diet, with only six being preferred in autumn. These are thus the plant species that could be the most vulnerable to white rhino herbivory. Supplementary food provision plays a big part of the feeding scheme of white rhino in Shamwari Private Game Reserve during the winter season, revealing the little confidence that the management has on natural resource availability to the animals at this time. These findings support the value of the Eastern Cape for ex situ conservation of white rhino, and highlight plant species potentially at risk. There is a need for further research on the population performance of these animals, and the plants identified here need to be monitored to assess white rhino impact on the vegetation

- Description: Migration is recognised as an escalating phenomenon of human behaviour worldwide. In the Southern African region African migrations and migrants have remained a focal point of discussion amongst politicians, citizens and migrants themselves in recent years. In South Africa, a major destination of migrants from various African Diasporas, this renewed interest in the topic has occurred in the context of xenophobic related violence aimed at foreigners within the broader economic, political and social arena. These factors extend to South Africa’s relationships with her near neighbours. Thus, Zimbabwe’s political, economic and social crisis has overflowed into South African borders, contributing large numbers of migrants to her population. Previous research has underrepresented the perspectives of migrants and Zimbabwean migrants in particular. Zimbabwean migrants seek economic opportunities to better themselves and maintain the survival of their families who remain in their country of origin. They are transnationals who engage in continuous movement between one place and the next, supporting various livelihoods. Little is understood about migrant adaptation to their complex contexts. In this research project, content analysis was conducted of data gathered during interviews and participant-observation of Zimbabwean migrant traders on the beachfront informal market in Port Elizabeth. The maintenance of the cultural values and identity of the myth of the hero as upholder of household honour was found to be significant in the adaptation of migrants to their multi-faceted lives. The findings indicate that migrant life is indeed uncertain and ever-changing. Their resilience in the face of continual change illustrated both conflict and compromise between “social cohesiveness (and) social flexibility” (Bauman, 1998: 15-16)

- Description: An adequate understanding of the nature of science (NOS) has become increasingly important for science teachers in South Africa as comprehensive curricular reforms over the past decade include promoting informed understandings of the ontological and epistemological bases of scientific knowledge and the methods of science. The main objective of this study was to explore the NOS understandings held by a sample of science teachers in the Eastern Cape Province of South Africa. Data were generated via questionnaires (n=136), semi-structured interviews (n=31), and classroom observations (n=8). The teacher interviews, which were informed by the questionnaire data, enabled further interrogation of the teachers’ philosophical positions. Their classroom practices were examined within the framework of these philosophical positions and the requirements of the new curriculum. The effect of implicit and explicit instruction in NOS on these teachers’ beliefs and classroom activities was also considered. A mixed-method approach informed by positivist and interpretivist perspectives was used for the collection and analysis of the data. The data suggests that explicit instruction in NOS resulted in more informed conceptions of science and the scientific enterprise, and that these conceptions were reflected, to a degree, in their classroom behaviours. However, it was noted that the teachers in this study often held philosophically eclectic views of the nature of scientific knowledge and how scientists develop ideas. Similarly, the South African National Curriculum Statement portrays science in contrasting ways, i.e. often within a modern/realist framework, but in other instances within postmodern/relativistic understandings (particularly in terms of indigenous knowledge systems). As such, an approach which aims at providing a firm foundation for understanding NOS ideas within a modern/realist perspective before emphasising the postmodern/relativist aspects of the scientific enterprise is suggested for teacher training and curriculum development.

- Description: This research aimed to trace the development of psychologists as therapists within a South African context. Two distinct career levels were explored in relation to a competency model, a skills development model, and a developmental phase model of psychotherapists' professional development. Through purposive sampling five intern psychologists and six registered psychologists with at least seven years post-qualification client contact were selected according to the inclusion criteria of the study. Through semi-structured interviews, couched in the social constructionist position, the participants' experiences were thematically analysed. In addition, the researcher's own personal journey of developing as a psychotherapist was reflected upon. The current research study found that a number of aspects fostered the development of psychotherapists. Across the two career levels the life experiences of participants particularly featured events that were personally wounding or placed the participant in the helper role. The theoretical orientation(s) of participants were voiced as influential in their development, yet the ability to adjust their theoretical orientation to clients' needs was of overriding importance. Participants emphasised forming a strong therapeutic relationship with clients as the centrepiece of psychotherapy and depicted the therapeutic process using diverse metaphors. No key differences in use of metaphors emerged between intern and established psychologists. Catalysts for professional growth included personal therapy, "unforgettable cases", group supervision and, in the case of established psychologists, continuing professional development workshops. xiii Shifts in competency were recognised by intern psychologists as they gained more experience, namely, dissolution of naivety, a decrease in anxiety regarding their clinical work, a greater flexibility in the therapeutic process, a decreased sense of inappropriate responsibility for clients' progress, and an ongoing process of negotiating the interface of their personal and professional lives. Established psychologists spoke of having gained more confidence through their years of practice and yet experienced moments of anxiety which they found fostered humility. Limitations of the study and potential future research directions were outlined.

- Description: When children are sexually abused it usually takes place in concealment. This means that unless the child reveals the abuse, it will remain hidden. This study commences with an examination of the reasons as to why a child may delay the disclosure of sexual abuse. The result of research indicates that there are certain recognisable reasons, which are frequently encountered, as to why a child may either delay telling anyone about his or her experience or as to why s/he may never tell anyone. Traditional assumptions of what are considered normal reactions to sexual abuse are tested. The discussion then moves on to considering the approach of the South African courts in regard to evaluating the manner and timing of a child’s revelations, as well as to considering the impact which a delay may have on the acceptance of that child’s evidence. Intrinsic to this analysis is the progress made in our courts, and by the legislature, in recognising factors that influence a child to either blurt out the information immediately or conceal it for a period of time. Thereafter, the testimony of 97 child victims of sexual abuse is analysed with a view to determining whether these children fit the profiles raised in research on the subject and described in some of the case law. The rate of attrition in cases of sexual offences against children is considered as well as the role that cross-examination plays in either enhancing or reducing a child’s ability to accurately describe an acceptable motivation for the delay in disclosure. The study concludes with a discussion of how well child victims are served in a legal environment designed to provide a forum for eliciting the truth from a child witness. The use of intermediaries and the impact of cross-examination is discussed as well as the ability of judicial officers to adjudicate in matters requiring highly specialized knowledge and experience.

- Description: In 2002 there were an estimated 1.5 million people admitted into casualty emergency units within the Republic of South Africa. Many of these admissions dealt with events that were traumatic for both families and practitioners and these traumatic events have effects on the biological, psychological and social wellbeing of these individuals. Coupled with this is an ever increasing demand for mental health services and a worldwide shortage of qualified individuals to provide these services. Registered nurses in casualty units deal with the majority of these issues and the effect of these traumatic events. The crisis intervention model may provide these registered nurses with the necessary skills to deal with these problems not only for patients but possibly for themselves. Furthermore the biopsychosocial model of health allows these registered nurses to assess the impact of these events on the individuals. Yet, some registered nurses feel that they lack the necessary skills to deal with and assess these problems and intervene in these crisis situations. This study was exploratory descriptive in nature and aimed to examine whether there was a perceived need for registered casualty unit nurses to engage in supplementary counselling skills training. These perceptions were obtained through purposively sampled interviews and analysed qualitatively, using Tesch’s model of content analysis. Findings indicated that the registered nurses do perceive a need for supplementary counselling training, both for use with the patients and for themselves, and are willing to engage in this training although there are problems that inhibit this willingness. Recommendations regarding the implementation of a supplementary counselling skills training course as well as future research in the field were made.

A non-probability purposive sampling method was used to select eight participants from Komani Hospital in Queenstown. Data was collected through semi-structured interviews. The services of an Independent Interviewer were used to avoid any bias as interviews took place where the researcher is employed. All interviews were transcribed verbatim and the data collected was analyzed according to Tesch’s eight steps of data analysis as described in Cresswell (1994:155). The researcher utilized services of an Independent Coder who verified the identified major themes. Four major themes emerged from the analysis of the interview: Mental health care practitioner’s perceptions of mental illness, perception of the causes of mental illness within the isiXhosa cultural context, mental health care practitioners’ views in the management and treatment of mental illness and suggestions put forward to improve the services to mental health care users. The major findings of this study were the lack of knowledge of culture of mental health care users. It is recommended that it would be proper if there could be co-operation between mental health care practitioners and traditional healers by working together as a team.

- Description: The research problem addressed in this study was to establish how small- to medium-sized furniture manufacturing businesses could develop a technology strategy that would improve their competitiveness. Therefore, the primary objective of this research study was to develop a technology-strategy framework for small- to medium-sized furniture manufacturers to assist them to improve their competitiveness. Research has indicated that small- to medium-sized furniture manufacturers have the potential to contribute to South Africa‟s economic growth, job creation and gross domestic product. However, research has also indicated that small- to medium-sized furniture manufacturing industries have not kept up with technology developments and, as a result, competiveness is on the decline. Low-technology businesses, such as those found within the furniture manufacturing industry, often have no framework or methodology to guide the successful acquisition and integration of technology to enable a more competitive business. The main problem was addressed in three phases. Firstly, a literature review of strategy and technology-related factors was conducted which provided valuable insight into the development of a strategic framework. This included identification of the business strategy, external and internal factors influencing technology requirements, technology integration, -selection and criterion for competitiveness. Secondly, an empirical study consisting of both a quantitative and qualitative investigation was performed. The quantitative measuring instrument used was a questionnaire designed from the literature study information and was administered to a stratified sample of small- to medium-sized furniture manufacturers. The quantitative results were triangulated by qualitative interviews with selected respondents. The empirical results revealed a strong relationship between technology and competitiveness (as measured by business performance and technology- iv competitive advantage), thereby confirming the importance of technology utilisation for small- to medium-sized furniture manufacturers and the significance of developing a technology-strategy framework. Thirdly, by combining the literature study information and findings from the empirical investigation, the technology-strategy framework was developed. The technology-strategy framework provides a roadmap to integrate technology with the business strategy. The technology-strategy framework is used in three phases, firstly, the business strategy is identified, secondly, the technology-strategy framework provides a guide to identify and forecast technology, conduct an internal audit and identify technology that can execute the business strategy. The final phase is the application of criteria by means of which competitiveness improvement is assessed. Ultimately, the technology-strategy framework can facilitate improved competitiveness of the furniture industry.

- Description: This study investigates the implementation of supermarket-based scheduling of parts at a South African exhaust manufacturing plant. The study firstly investigates the requirements the manufacturer had to contend with in ensuring a valuable contract was won. The nature of the contract is such that it warrants building of a new facility. The design of the facility and the manufacturing processes is of importance as some Lean techniques are employed during these early stages. The research takes the form of a case study and data is collected mainly through interviews with staff, but also from direct observations on the shop-floor. Interviews were conducted with: - key project leaders responsible for the original design and commissioning of the facility; - production managers and technical staff currently operating the plant; and - shop-floor personnel involved in daily production and logistics operations within the plant. The as-built facility and procedures are compared with literature found on the topic of Lean manufacturing. Various findings are recorded, both on conforming to and not conforming to typical Lean theory. Potential changes are suggested in the following areas: - a Pull strategy is proposed to coincide with the appointment of a so-called pacemaker station; - a pacemaker would need to be further supported by a production leveling strategy; - although quality delivered to the customer is reported as very high, potential improvements are still possible by introducing an "at source" approach to reduce rework; and - finally, a Total Productive Maintenance (TPM) program will serve to reduce downtime even further.

- Description: Novel non-leaving groups were employed in this dissertation to synthesize platinum complexes which can assist in the understanding or improvement of anticancer action. Emphasis was placed on (NS)-chelate and (NN)-chelate platinum complexes. Bidentate (NS)-donor ligands were used as non-leaving ligands in the synthesis of platinum(II) complexes with iodo, chloro, bromo and oxalato groups as leaving groups. These complexes were synthesized and studied since many questions regarding the interaction of sulfur-donors and platinum still exist. These relate to thermodynamic and kinetic factors and their influence on anticancer action. In this dissertation the properties of novel platinum(II) complexes of a bidentate ligand having an aromatic nitrogen-donor atom in combination with a thioethereal sulfur atom capable of forming a five-membered ring with platinum(II) were studied. The general structure of the (NS)-ligands used was 2-((alkylthio)methyl)pyridine. Alkyl groups used were methyl, ethyl, propyl, benzyl and phenyl. Amine complexes of platinum have been studied extensively in the past. However, attention was given to novel aspects of substituted pyridine and imidazole ligands and their corresponding complexes. Amongst these are 2-(2-methylaminoethyl)pyridine, 1-methyl-2-methylaminoethylimidazole and 1-methyl-2-methylaminobenzylimidazole. The leaving groups included chloro, bromo and oxalato. Mononitroplatinum(IV) complexes were prepared using novel synthetic methods. Selected platinum(II) amine complexes were used as starting materials for this synthesis. Some of these compounds exhibit promising anticancer behaviour. (Trans-(R,R)-1,2-diaminocyclohexane)(oxalato)(mononitrochloro)platinum(IV) is a particularly good anticancer agent and has been patented internationally. All these complexes were characterized using mass spectrometry, chromatography, thermogravimetric analysis, kinetic aspects such as ligand exchange rates and finally their anticancer action against three different cancer cell lines was evaluated via cytotoxicity assays. Some of the compounds exhibited particularly good anticancer potential.

- Description: Over the last 10 years the South African fiscus has introduced numerous changes to the Income Tax Act (ITA) which affect the income tax implications of persons ceasing to be a resident of South Africa. The two main changes were: - The introduction of a world-wide basis of taxation for residents - The introduction of capital gains tax (CGT) as part of the ITA The aim of this treatise was to identify the income tax implications of persons ceasing to be a resident of South Africa. Resulting from this research, several issues in the ITA have been identified, and the two major ones are summarised below. Firstly, upon the emigration of the taxpayer, there is a deemed disposal of a taxpayer’s assets in terms of paragraph 12 of the Eighth Schedule. It is submitted that the resulting exit tax may be unconstitutional for individuals. It is recommended that South Africa should adopt the deferral method within its domestic legislation for individuals who are emigrating. The deferral method postpones the liability until the disposal of the asset. Secondly, on the subsequent disposal of assets by former residents where there was no exit charge in terms of the exemption under paragraph 12(2)(a)(i) of the Eighth Schedule. Depending on the specific double tax agreement (DTA) that has been entered into with the foreign country, taxpayers have been given vii the opportunity to minimise or eliminate the tax liability with regard to certain assets. This should be of concern from the point of view of the South African government. Further issues noted in this treatise were the following: - It is submitted that the term ‘place of effective management’ has been incorrectly interpreted by SARS in Interpretation Note 6. - It is further submitted that the interpretation by SARS of paragraph 2(2) of the Eighth Schedule is technically incorrect. The above issues that have been identified present opportunities to emigrants to take advantage of the current tax legislation. It is further recommended that taxpayers who are emigrating need to consider the South African domestic tax law implications, respective DTA’s, as well as the domestic tax laws of the other jurisdiction, not only on the date of emigration but also on the subsequent disposal of the respective assets.

Development of insulin resistance in a rat model and the effects of sutherlandia frutescens as treatment and prevention

- Description: The global number of obese people has reached pandemic proportions. High caloric diets and reduced physical exercise are to blame for this growing epidemic. Obesity has a very complex association with several other metabolic disorders, such as insulin resistance (IR), diabetes mellitus type 2 (DMT2) and cardiovascular disease. This puts a huge burden on health care systems world wide and claims many lives. Sutherlandia frutescens is a traditionally used herb, which is known to have anti-diabetic properties. However, the direct mode of action of S. frutescens still remains to be elucidated. The aim of this study was to investigate the developmental stages of high fat diet (HFD)-induced IR, to illuminate the pathogenesis of IR with a focal point on modifications in the lipid metabolism. Furthermore, the effects of S. frutescens as a treatment or prevention drug for IR and associated metabolic changes were examined. Two sets of experiments were conducted on male Wistar rats. In the first experiment rats, one week post weaning received a low fat diet (LFD), high fat diet (HFD) or HFD supplemented with S. frutescens (50mg/kg BW/d). Rats were sacrificed at week 0, 1, 2, 4, 8 and 12 in the feeding regime. In a second experiment rats were fed with a LFD or a HFD for 12 weeks and treated thereafter with S. frutescens (50mg/kg BW/d), metformin (13mg/kg BW/d) or water (control) for 28 days. Rats in the second experiment were sacrificed at week 12 to confirm IR while concurrently run rats were sacrificed after 28 days of treatment. For all the experiments rats were anaesthetized, blood was removed and rats were dissected. Plasma samples were analyzed for insulin, glucose, blood lipid parameters and cytokines. Liver, muscle and adipose tissue were analyzed for glucose uptake, total lipid content, lipid profile and fatty acid profile. It was shown that the intake of HFD caused IR and hyperinsulinaemia. The developmental stages in experiment one confirmed that an increase in plasma free fatty acids preceeded the onset of IR. Plasma and tissue lipid parameters (free fatty acid-, triglyceride- and cholesterol concentrations) showed pathological modifications in the HFD group. An ectopic accumulation of fat was observed in muscle and liver, as well as a change in membrane fatty acid profile. The results for circulating cytokines were somewhat inconclusive. Rats supplemented with S. frutescens did not develop HFD-induced IR (study one) or IR was reversed (study two). S. frutescens treatment also resulted in positive changes in plasma and tissue lipid parameters. In summary, an animal model for HFD-induced IR was established and the detrimental effect of elevated plasma FFA on glucose and lipid metabolism was observed. A novel discovery suggests that the anti-diabetic mode of action of S. frutescens is through modulation of lipid metabolism. It was also established that S. frutescens has the potential to prevent IR in vivo.
