- Description: This study was conducted in Grahamstown in the Eastern Cape, South Africa. It is a qualitative case study located within the interpretive paradigm and was carried out over a period of a year. The theory implicit in the interpretive paradigm is of human beings as interpreters and constructors of a meaningful world. Thus, the focus of this study was on investigating the benefits of indigenous ways of knowing about wild food plants (imifino) in conjunction with hands-on activity-based lessons. This was done with the view to promote a conceptual understanding of nutrition and conservation in the Natural Sciences. The transformation of the school curriculum in South Africa called Curriculum 2005 (C2005) underpinned by the outcomes-based education (OBE) philosophy also triggered this study. The C2005 and OBE emphasise that learners’ prior everyday knowledge should be taken into account during the teaching and learning processes. The intention of the curriculum is to promote the idea of grounding knowledge in local contexts, while being sensitive to global imperatives. Although the acquisition of western knowledge has been and still is invaluable to all, on its own, it has been incapable of responding adequately to modern society in the face of massive and intensifying disparities, untrammeled exploitation of resources, and rapid depletion of the earth’s natural resources. Essentially, indigenous knowledge systems represent both a heritage and resource that should be protected, promoted, developed and, where appropriate, conserved. It is a resource that should serve the present and succeeding generations as many people’s cultural practices still rely on the use of wild plants. Within this context it should be borne in mind that the overexploitation of natural resources threatens not only biodiversity but also local traditional knowledge systems and ultimately cultural heritage; and research has a role to play in this regard. The research process in this study evolved into two main phases. The initial phase involved mobilising Grade 7 learners’ prior everyday knowledge on wild food plants (imifino). This led to the second phase of the research project, which was aimed at developing concepts through three hands-on activity-based lessons. I invited a community member to give a lesson on what imifino is and how to collect and prepare it, with the belief that the involvement of parents and community members in learners’ education can help bridge the gap between everyday life and school science. It is for these reasons that I believe that the constructive perspective can provide an appropriate methodological framework, conceptual structure and terminology for analysis of teaching and learning activities on the use of wild food plants in this study. The data generation techniques used in this study were questionnaires, observations and interviews (semi structured and focus group). A wide range of data generation techniques were employed to crystallise and validate the data generated using triangulation. The results from the analysed data revealed that consideration of indigenous ways of knowing in conjuction with hands-on practical activities enhanced interaction and learning among the learners. Also, linking of scientific knowledge to learners’ everyday lives was useful in fostering meaning-making and conceptual development.

- Description: The new South Africa has an amazing economic growth that creates a significant opportunity for international companies to start their businesses in South Africa. For those companies which are interested in the South African market, it is very important for them to understand the factors that influence their entry-mode selection. The objective of this study is to determine the main factors that have an impact on the decision of a foreign business to enter South Africa. To achieve this objective, the researcher used an integrated study method, as follows: {u10007A} A systematic review of the popular entry-modes and the main factors influencing the entry-mode selection, sourced from the relevant literature. In addition, South African business was also introduced. {u10007A} Based on the factors related in the literature, an empirical survey was completed by those foreign companies who had already successfully entered into South Africa, in order to figure out the rank importance of these factors. With an integrated study of literature and empirical research, the rank importance of factors that have an impact on the foreign business entry-mode selection in South Africa is as follows: 1. Firm’s product 2. Control level of entry-mode 3. Ownership of entry 4. Resource commitment of entry-mode 5. Political factor 6. Firm’s objective 7. Technological factors 8. Economic factors 9. Firm’s experience in international marketing 10. Firm’s size 11. Dissemination risk of entry-mode 12. Socio-cultural factors 13.

- Description: Nursing lecturers are faced with the challenge to adapt their teaching styles and attitudes to accommodate the new nursing student that enters the nursing field. These students have expectations and demands which differ highly from past students. Another challenge for lecturers is the demands of a nursing curriculum. The students that commenced with the four year course during 2005 at the Port Elizabeth Nursing Campus experienced negativity with regards to their training. The objectives of the study are to explore and describe the training experiences of the fourth year student nurses of the Port Elizabeth Nursing Campus and to co-construct guidelines to assist nursing lecturers to gauge the understanding of students during their four years of nursing training. The participants used for the study were all fourth year nursing students. They had positive and negative experiences of their training during the four years. The negative experiences related to the demands of the curriculum, lecturers’ poor subject knowledge and insufficient material resources needed for their studies. Regardless of the negativity experienced, students encountered positivity with regards to lecturers’ attitudes. The researcher focused on a qualitative study using an explorative, descriptive, contextual and phenomenological approach. A semi-structured approach was adopted to obtain data. Once consent was obtained from the relevant authorities, four fourth year nursing students were interviewed. The interviews were conducted by an independent role-player within the Department of Health to ensure an unbiased approach. Guba’s model was used to assess trustworthiness and data was analysed. Ethical considerations were ensured throughout the research process. Themes and sub-themes were identified. Based on the research findings, guidelines were co-constructed to assist nursing lecturers to better understand nursing students during their training. The findings of the study will be brought to the attention of nursing lecturers and management personnel of the campus. It was concluded that nursing students need to be consulted on issues concerning their training and development before implementation, and that they be respected and cared for as students based on their human rights.

- Description: The purpose of this study was to develop an optimal skills development planning and implementation process flow model for application within local government authorities, more specifically for application within the Nelson Mandela Bay Municipality. To achieve this, a literature review was conducted which provided for an understanding on how skills development structures and strategies have changed in recent times and how the laws which provide the framework and landscape for skills development in South Africa, have been adapted to accommodate these changes. The literature review continued with an analysis of various theoretical training and skills development models in order to determine an optimal systematic approach to training and development in South Africa, and to determine the sequential flow of skills planning and implementation process flow steps. From the literature and theoretical models, an all-embracing skills development planning and implementation process flow model was developed for implementation in local government authorities. This model was used as the basis for the development of a survey questionnaire to establish to what extent metropolitan municipalities, agreed or disagreed, that it implemented the aspects of the proposed model developed in this study. Structured interviews were conducted using the survey questionnaire. The results obtained were used to adapt the theoretical model, and to align it with the viewpoints of the majority of the respondents. Although various facets of skills development were found to be implemented across metropolitan municipalities, the majority of the municipalities did not apply optimal skills planning, nor did they apply optimal sequential process steps to ensure effective and efficient skills development. iv The empirical study established without a doubt that a dire need exists for an optimal skills development planning and implementation process flow model within local government authorities. Based on the analysis and interpretation of the research findings, the model proposed for local government authorities was customised to produce a process flow model to facilitate optimal skills development planning and implementation within the Nelson Mandela Bay Municipality.

- Description: American options are the most commonly traded financial derivatives in the market. Pricing these options fairly, so as to avoid arbitrage, is of paramount importance. Closed form solutions for American put options cannot be utilised in practice and so numerical techniques are employed. This thesis looks at the work done by other researchers to find an analytic solution to the American put option pricing problem and suggests a practical method, that uses Monte Carlo simulation, to approximate the American put option price. The theory behind option pricing is first discussed using a discrete model. Once the concepts of arbitrage-free pricing and hedging have been dealt with, this model is extended to a continuous-time setting. Martingale theory is introduced to put the option pricing theory in a more formal framework. The construction of a hedging portfolio is discussed in detail and it is shown how financial derivatives are priced according to a unique riskneutral probability measure. Black-Scholes model is discussed and utilised to find closed form solutions to European style options. American options are discussed in detail and it is shown that under certain conditions, American style options can be solved according to closed form solutions. Various numerical techniques are presented to approximate the true American put option price. Chief among these methods is the Richardson extrapolation on a sequence of Bermudan options method that was developed by Geske and Johnson. This model is extended to a Repeated-Richardson extrapolation technique. Finally, a Monte Carlo simulation is used to approximate Bermudan put options. These values are then extrapolated to approximate the price of an American put option. The use of extrapolation techniques was hampered by the presence of non-uniform convergence of the Bermudan put option sequence. When convergence was uniform, the approximations were accurate up to a few cents difference.

- Description: The objective of the study was to identify and document facilitating and constraining factors in the antiretroviral therapy (ART) programme in a public health care setting in the Eastern Cape, South Africa. Observations for the study were carried out in a district hospital and two down-referral clinics in Makana Local Services Area in the Eastern Cape Province. Two discussion groups with key stakeholders were conducted to gather information about opinions and experiences among the health care providers (HCPs). It was found that the operating ART programme in this setting has been integrated in the existing down-referral health care system, based on follow-up in primary health care (PHC) clinics. Treatment is provided free of charge. The treatment programme provides the patients with access to counselling, nutritional assistance, psychosocial support and social welfare evaluation. However, increasing patient numbers and lack of human resources leads to a heavy workload for the HCPs involved with the ART programme. The need for additional, educated health workers is a major constraint for progress in provision of health care to patients who have accepted their HIV status, and are enrolled, or waiting to be enrolled, on the ART. However, delegation of work tasks among available HCPs and good communication between HCPs in the different clinics is a facilitating factor that ensures efficient use of the human resources available. Conclusion: Taking into account the challenges in a resource-constrained setting, this programme shows potential for functioning well as a provider of ART for those who are able and willing to access it. Considering an already heavy workload for HCPs, limitations and challenges still exist in reaching out with adequate treatment to a greater number of people who need ART.

- Description: A recent isolated population of Apis florea has been reported from Aqaba in Jordan at the Red Sea, consisting of numerous colonies within a still limited range which apparently is expanding. This region is about 1500 km apart from its next occurrences in Sudan where it had been introduced and first detected in 1985 and about 2000 km apart from its next natural occurrences in Iran and Oman. These bees apparently have been imported by human transport, most likely by ship. This new location thus represents a major jump in the progression of the species still to fill a wide area of possible locations offering adequate living conditions. Here we attempt to track the possible origin of this new population by morphometric methods. This analysis indicated closest relation to A. florea from Oman, thus being the most likely source of this population.

- Description: Baylis-Hillman reactions using various aromatic aldehydes, activated alkenes and catalysts have been used to: - access an extensive range of poly-heterocyclic products;explore chemoselectivity; and optimise reaction efficiency. Chromone-3-carbaldehydes and chromone-2-carbaldehydes, prepared via Vielsmeier-Haack and Kostanecki-Robinson methodology, respectively, have been used as Baylis-Hillman substrates with four different catalysts, viz., 1,4-diazabicyclo[2.2.2]octane (DABCO), 3-hydroxyquinuclidine (3-HQ), imidazole and N’,N’,N’,N’- tetramethylpropanediamine (TMPDA), and with methyl vinyl ketone (MVK), methyl acrylate, cyclic enones (2-cyclohexen-1-one, 2-cyclopenten-1-one and chromones) as activated alkenes. Reactions of the chromone- -carbaldehydes with MVK afforded dimeric Baylis-Hillman adducts when catalyzed by DABCO but when the same reactions were repeated using 3-HQ as catalyst, the dimeric products were accompanied by tricyclic Baylis-Hillman adducts. Use of excess MVK, however, led to mixtures of the normal Baylis-Hillman adducts and the tricyclic adducts – interestingly, with the apparent absence of the dimeric products. While reactions of chromone-3-carbaldehydes with methyl acrylate afforded the normal Baylis-Hillman adducts, the chromone-2- carbaldehydes produced, instead, rearrangement products, consistent with an earlier, single observation. Reactions of 2-nitrobenzaldehydes with cyclic enones using imidazole as catalyst afforded the normal Baylis-Hillman adducts, reductive cyclisation of the 2-cyclohexen-1- one and 2-cyclopenten-1-one adducts, using acetic acid and iron powder, afforded the corresponding quinoline erivatives. Treatment of cyclic enones with pyridine-2-carbaldehydes and quinoline-2-carbaldehydes using TMPDA as catalyst generally gave the expected Baylis-Hillman adducts. However, indolizine derivatives were isolated directly from Baylis-Hillman reactions involving pyridine-2-carbaldehydes and 2-cyclohexen-1-one. The remaining Baylis-Hillman adducts were cyclized to the corresponding indolizines by treatment with acetic anhydride both under reflux and under microwave-assisted conditions, the latter approach providing remarkably rapid and efficient access to the polycyclic products. Computer modelling studies have been conducted on selected polycyclic products at the Molecular Mechanics (MM), Quantum Mechanical (QM) and Density Functional (DFT) levels. The theoretical results have been used to calculate UV, IR and NMR absorption data, which have been compared, in turn, with the experimental spectroscopic data. Use has also been made of the estreNova NMR prediction programme and, generally, good agreement has been observed between the predicted and experimental spectroscopic data.

- Description: The propagation of radio signals in the Earth’s atmosphere is dominantly affected by the ionosphere due to its dispersive nature. Global Positioning System (GPS) data provides relevant information that leads to the derivation of total electron content (TEC) which can be considered as the ionosphere’s measure of ionisation. This paper presents part of a feasibility study for the development of a Neural Network (NN) based model for the prediction of South African GPS derived TEC. The South African GPS receiver network is operated and maintained by the Chief Directorate Surveys and Mapping (CDSM) in Cape Town, South Africa. Vertical total electron content (VTEC) was calculated for four GPS receiver stations using the Adjusted Spherical Harmonic (ASHA) model. Factors that influence TEC were then identified and used to derive input parameters for the NN. The well established factors used are seasonal variation, diurnal variation, solar activity and magnetic activity. Comparison of diurnal predicted TEC values from both the NN model and the International Reference Ionosphere (IRI-2001) with GPS TEC revealed that the IRI provides more accurate predictions than the NN model during the spring equinoxes. However, on average the NN model predicts GPS TEC more accurately than the IRI model over the GPS locations considered within South Africa.

- Description: In this thesis I discuss three normative claims that I take to be central elements of Charles Taylor’s political thought. The first of these is Taylor’s contention that, in contemporary pluralistic societies, justifying socially prevailing norms by appealing to universally binding moral values is unlikely to promote social solidarity. Because this approach tends to downplay the goods that people realise through membership in particular associations, Taylor believes we must adopt a model of justification that does not prioritise universal over particular goods if we are to further social co-operation. A second claim Taylor defends is that commitment to the liberal value of collective self-rule implies treating patriotically motivated public service as a non-instrumental good. We should not, Taylor argues, regard collective association as nothing more than a means to satisfying private goals. Taylor advances a third claim, that is, he maintains that liberal toleration for diverse ways of life may require a perfectionist state that supports particularistic ways of life when they are threatened by decline. I offer a qualified defence of the first two claims, but suggest that the third is less compelling. I attempt to do this by evaluating Taylor’s claims against the standards of lucid argumentation that he himself lays down. In discussing social and political norms, which he describes as “advocacy” issues, Taylor argues that our normative commitments necessarily rely on an underlying social ontology. More specifically, Taylor argues that the political values we defend are those that enable us to secure the interests we have as the bearers of an identity possessing both individual and collective dimensions. In setting out the conditions that favour integrated and free identity formation we may thereby reach a clearer understanding of the political norms that we wish to endorse. I argue that, while Taylor’s ontological reflections might well incline us to accept his model of justification and his account of patriotic social commitment, they do not of themselves dispose us to accept state perfectionism.

- Description: Over three decades of research has shown that memories have significant effect on the behaviour, attitudes, beliefs, and identities of individuals and collectives, revealing also how experiences of trauma and acts of narrativisation have pertinence to the ways in which memories are stored and reconstructed. In this thesis a link is developed between memory, trauma, narrativisation processes and the interpretation of works by Jane Alexander, a contemporary artist whose work is informed by observations about South African life. Alexander’s sculptures are revealed to be not only important vessels of collective memories and experiences, but also evocations of individuals’ countermemories and traumas that remain unarticulated and invisible. Through an exploration of the workings of memory and its relation to her art, it is revealed how the past continues to exert its influence on many of South Africa’s present sociopolitical concerns and interpersonal dynamics. Indeed constantly changing memories have a significant effect on future generations’ perceptions of, and connectedness to, the past. While theories about memory have been deployed in Art History as well as the Humanities in general, Alexander’s work has not previously been considered in light of the influence of these ideas. This thesis thus contributes a new dimension to literature on the artist.

Aspects of the ecology and biology of the isopod, Exosphaeroma hylocoetes, (Barnard, 1940) in three temporarily open/closed southern African estuaries

- Description: Temporarily open/closed estuaries (TOCE’s) are the numerically dominant type of estuary accounting for ≈ 70 % of all estuaries along the South African coastline. Despite their numerical dominance, aspects of the biology of organisms within these systems, particularly macrocrustacea remain poorly understood. This study firstly assessed the abundance and biomass of the most common isopod, Exosphaeroma hylocoetes, in three Eastern Cape TOCE’s, (the West Kleinemonde, East Kleinemonde and Kasouga Estuaries), and their response to mouth breaching events. This study was followed by aspects of the biology of the isopod including their utilisation of submerged macrophytes as a refuge from predation and/or possible food source, as well as the growth rates of the isopods in the laboratory under different environmental conditions. Mean isopod abundances and biomasses ranged between 0 and 4 791 ind. m⁻² and 0 and 9.65 mg dwt. m⁻² in the West Kleinemonde Estuary and between 0 and 108 ind. m⁻² and 0 and 0.318 mg dwt. m⁻² in the nearby East Kleinemonde Estuary. In the Kasouga Estuary, the values ranged between 0 and 3 650 ind. m⁻² and 0 and 5.105 mg dwt. m⁻². Temporal and spatial changes in the abundance and biomass of E. hylocoetes within the three systems was primarily linked to mouth phase, with populations declining when the mouth was open and to a lesser extent, seasonality. In all three estuaries maximum isopod abundances and biomasses were recorded in their middle and upper reaches, which could be ascribed to the presence of submerged macrophytes particularly Ruppia maritima, in two of the estuaries. Males (5.71 ± 0.41 mm) were significantly larger than females (3.99 ± 0.26 mm), but the sex ratios were skewed in favour of females, (a common feature in many isopod populations). Females were found carrying brood throughout the study, releasing offspring directly into the water column, to allow recruitment to the populations. The larger the female, the larger the brood carried (up to a maximum of 72 embryo/mancas). Results of laboratory experiments indicate that the close association of Exosphaeroma hylocoetes with submerged macrophytes is a result of the plant stands providing a refuge against predation by selected ichthyofauna. However stable carbon isotope and fatty acid analyses indicate that E. hylocoetes made use of ephiphytic algae and detritus on the stems of R. maritima, rather than the submerged macrophyte itself. There were no significant differences in the growth rates of male and female isopods at combinations of temperature (15 and 25 °C) and salinity (15 and 35 ‰). Laboratory growth studies revealed that males lived longer than females (25.77 ± 3.40 weeks vs 21.52 ± 3.00 weeks), and therefore achieved larger overall size. Females, however, reached sexual maturity (at 2.5 mm) at a faster rate (two to four weeks) than males (5.5 mm after 6.5 to 11 weeks), dependent on temperature. Exosphaeroma hylocoetes with its association with submerged macrophytes, early maturity, its growth rates and longevity, female-biased sex ratios and year-round breeding, all contribute to its success in temporary open/closed estuaries.

Results of laboratory experiments indicate that the close association of Exosphaeroma hylocoetes with submerged macrophytes is a result of the plant stands providing a refuge against predation by selected ichthyofauna. However stable carbon isotope and fatty acid analyses indicate that E. hylocoetes made use of ephiphytic algae and detritus on the stems of R. maritima, rather than the submerged macrophyte itself. There were no significant differences in the growth rates of male and female isopods at combinations of temperature (15 and 25 °C) and salinity (15 and 35 ‰). Laboratory growth studies revealed that males lived longer than females (25.77 ± 3.40 weeks vs 21.52 ± 3.00 weeks), and therefore achieved larger overall size. Females, however, reached sexual maturity (at 2.5 mm) at a faster rate (two to four weeks) than males (5.5 mm after 6.5 to 11 weeks), dependent on temperature. Exosphaeroma hylocoetes with its association with submerged macrophytes, early maturity, its growth rates and longevity, female-biased sex ratios and year-round breeding, all contribute to its success in temporary open/closed estuaries.

- Description: Entrepreneurship has emerged over the last two decades as arguably the most potent economic force the world has ever experienced (Kuratko, 2005: 577). Entrepreneurship has become a pressing national priority in South Africa as there are simply not enough existing jobs to absorb the influx of school leavers into the labour market (www.ssaci.org.za). The Global Entrepreneurship Monitor study has consistently highlighted the weaknesses in the education system as a factor limiting entrepreneurial activities in South Africa (Orford, 2004: 26). Entrepreneurship education was introduced into the Further Education and Training curriculum (Grades 10-12) in 2006 as part of an optional subject Business Studies (Horn, 2006: 120). Preliminary evidence suggests widespread problems across the country with the implementation of entrepreneurship education programs in schools (Isaacs, Visser, Friedrich and Brijlal, 2007: 618). The primary objective of this study is to improve entrepreneurship education at secondary school level by investigating how effective the current entrepreneurship education program is in providing school leavers with the entrepreneurial knowledge and skills required to start their own business. The study conducted a literature review to establish global trends of entrepreneurship education. Furthermore, a qualitative case study approach was used, where three schools from Nelson Mandela Bay Municipality was selected for collecting data on the progress of entrepreneurship education in secondary schools. The study found that prescribed content for entrepreneurship education is being taught at secondary schools. However, concerns were identified with the methods used to teach entrepreneurship education as it lacked practical exposure to real life situations. The study found that the way in which entrepreneurship education was taught did not motivate school leavers to start their own business. Therefore, the study recommends that entrepreneurship education should be offered as an independent subject and not as part of another subject. Furthermore, a practical approach should be followed in teaching entrepreneurship education. Finally, commitment and collaborative participation by all stakeholders are required to ensure the success of entrepreneurship education.

- Description: Quality of service becomes the main avenue that could be used to gain sustainable competitive advantage. This is due to the fact that the environment within which organisations operate continues to change with respect to customer expectations. The financial sector, in particular the banking industry is not left behind and players in this industry also strive to “up their game” in the competitive market-place. It has become increasingly important for organisations to find ways, not only to reach the top, but to maintain on-going long-term relationship with their customers. This can result in long-term benefits, both for the organisation (by improving marketing productivity) and for the customer (by delivering better quality products). This paper assesses the perception the Business clients/ customers within a business banking environment have about relationship management by Meeg bank in East London branch town of Eastern Cape. A literature survey was undertaken into the importance of Customer Relationship by bank. Questionnaires were sent to all employees of the business clients for their views on Customer Relationship Management (CRM). The result the show importance of the commitment of all employees’ especially senior management is essential for the success of CRM efforts in improving the quality of service offered by an organisation. The research also confirmed the importance of having wide range of options in form of products offered. This will not only benefit the bank in terms of higher profits, but will give the bank the competitive advantage in the market place.

- Description: The study sought to establish the impact of using the local content policy in reducing television cultural influences on Mbare youth in Zimbabwe. It is assumed that television has ideological and hegemonic functions which have come to dominate the life styles of the youths on issues of dress styles, musical tastes and language, thus threatening and weakening the long established local cultures. Hence the Zimbabwean government’s local content policy was established to reduce influences of alien cultures. This study, therefore, sought to establish if Mbare youth cultures confirm or reject the imitation of television cultures with regard to dress styles, music tastes and language. In addition, the investigation aimed at establishing the feasibility of using the local content policy to reduce foreign cultural intrusions vis-à-vis globalisation challenges. The three theories utilised in the discussion of the influence of television on Mbare youth culture in this study include the cultivation theory, the theory of hegemony and the uses and gratification theory. A qualitative study was adopted to gather data using focus group discussions, questionnaires and semiotic analysis. The sample of the study consisted of 87 participants and 4 Youth.com programmes. The study revealed that television has ideological and hegemonic functions. As such, it tends to be a dominant influence on the life styles and culture of Mbare youths. The study also established that Youth.com influences youth culture through music. In Zimbabwe music has become the most influential aspect of Youth.com despite not being specified in the local content policy on television broadcasting. Furthermore, the study shows that the implications of globalisation on local television content are undermining government efforts to preserve local cultures through the local content policy. The primary reason for this has to do with the fact that Youth.com programme does not contain a higher quota of local content as stipulated in the policy. However, although the local content policy was viewed as a political gimmick, the the study revealed that it was necessary in view of youths’ vulnerability to television’s ideological and hegemonic influences. Nevertheless, in view of the loopholes revealed by this study, the policy requires to be revised to cater for all the essential cultural elements, such as, music, which are allowing alien cultures to penetrate local ways of life. For instance, the urban groove music has major impacts on the culture of Mbare youths.
