- Description: There is limited research pertaining to assessing the happiness levels of various disciplines within the healthcare industry. Furthermore, happiness and physiotherapy studies are two research areas that are not necessarily associated with one another on a global perspective. Hence, the happiness levels have not been adequately established for private physiotherapists. This treatise is the first attempt to evaluate the happiness levels of private physiotherapists in South Africa. A thorough literature review was conducted to determine the current climate of happiness studies pertaining to the business industry, with focus on private physiotherapy businesses in the healthcare sector. The literature review enabled the development of a hypothesised model, which was tested with quantitative techniques consisting of a questionnaire, data collection and statistical analysis. The research confirmed that influence, social relations, life balance, optimism, work and leisure are all positively associated with the happiness levels of private physiotherapists in South Africa. These variables are recommended as key focus areas for physiotherapy business owners to address, in order to positively affect happiness levels in the workplace and thereby create favourable bottom line results. In accordance with the reviewed literature and the findings of this treatise, by adequately addressing these variables the business owners of physiotherapy practices will generate a workforce that are more productive, demonstrate greater collaboration with colleagues and customers, produce happier customers, are more positively energised and are less absent and more loyal to the business. It is recommended that the proposed model is tested to provide further benefit to the industry by constructing evidence-based retention and recruitment strategies for high performing private physiotherapy staff.

- Description: This thesis examines the history of the Honde Valley area, in Mutasa District, along the Zimbabwe-Mozambique border. It uses two historic developments: the Zimbabwe liberation war and RENAMO insurgency to explore daily life and mundane experiences of the borderland communities, mainly from the late 1970s to 2016. Because earlier historians of these two historic developments have been much interested in studying the aspects of violence and suffering, this study extends the focus of analysis to the mundane experiences. I argue that in borderland areas, there are other wartime aspects of life worth investigating other than violence and suffering. In doing so, the thesis deploys the notions of conviviality and the everyday to understand the daily experiences of the Honde Valley communities during the disruptions caused to everyday life by these wars. Admittedly, twentieth century wars in Zimbabwe and Mozambique transformed the area that had previously remained at the fringes of colonial power from 1890-1950, into a new and bitterly contested ‘sharp end’ of the war. Nonetheless, peoples’ experiences during these wars cannot be understood merely in relation to violence and suffering. Furthermore, I argue that although some families were forcibly moved into liberation war “Protected Villages ”, they innovatively designed new mechanisms and alternative lifestyles in response to the state’s routinised control. The thesis concludes that beyond the confines of war-induced violence and suffering, Honde Valley communities used their borderland location to evade the pressures of war and continued with life.

- Description: This study examines the socio-political role of the Christian church based women’s Manyano organisations in post-apartheid South Africa. Specifically, the study examines the ways in which the women’s Manyano organisations offer black women a site for the performance of citizenship. The study is based on life history interviews conducted with seventeen members of the Methodist Church Women’s Manyano of the Lamontville Circuit in Kwa-Zulu Natal. The study shows that dominant literature on Manyano women is primarily located in the historiography of the formation of Manyano groups within the historical development of the black church from the moment of missionary contact in South Africa. This literature shows that the missionaries used the coming together of black women in the church to promote ideas of devout domesticity that are based on Anglophone Victorian womanhood. This literature also shows that the structural constraints of colonisation and apartheid transformed the black church into a counterpublic space which focused largely on the liberation of the black majority from political, economic, and social exclusion from the colonial and apartheid public sphere. These constraints also transformed the role of women’s Manyano organisations to become an important space from which black women came to resist and defeat apartheid. This study shows that this historical framing of women’s Manyano groups has shaped their role in post-apartheid South Africa. Located in the African feminist theory, the study argues that Manyano women’s publicness is not limited to gendered expressions of the public and private sphere. Instead, Manyano women demonstrate that their publicness in post-apartheid South Africa ought to be understood through a combination of the varied identities that they straddle, such as those of a politically and culturally defined womanhood and communally based motherhood, which express their understanding and performance of citizenship. The thesis, therefore, argues that the contemporary role and functioning of Manyanos is located within both the hegemonic public sphere that is granted by the civil liberties of the new South Africa, and the historical black bifurcated counterpublic -which combined offer black women the ability to devise strategies to confront present-day socioeconomic challenges such as structural poverty that shapes the lives of the majority of black women in post-apartheid South Africa. The study contributes, therefore, to the reconstruction of the concept of the public sphere through the use of Manyano women’s dynamic position in post-apartheid South Africa. It shows that the dualist nature of Manyano women’s position and identity allows for a multifaceted approach in the understanding of citizenship for Manyano women today. Furthermore, and importantly, the study shows that the complex roles that Manyano women navigate within the different spheres complicate the interpretations of womanhood and motherhood as understood in dominant (white western) feminist theory in ways that often lead to the delegitimisation and erasure of Manyano women’s contributions to ideas about post-apartheid feminisms.

- Description: This thesis provides a unified analysis of ellipsis in the vP domain in two typologically different languages, Mandarin and Xhosa from a generative perspective. It starts with the V-stranding Verb Phrase Ellipsis (VPE) assumption and shows that Mandarin and Xhosa do not have V-stranding VPE. The evidence for this is that in both languages, the constituents that remain in vP obligatorily are not allowed to be deleted, whereas the ones that can/must move out of vP can be deleted. The deleted constituents display the characteristics of PF-deletion, i.e. they have an internal syntactic structure. Based on the parallel between movement and ellipsis of the vP-internal constituents, I propose the Ellipsis EPP Hypothesis to account for ellipsis in the vP domain. The Hypothesis predicts that there is an Ellipsis Phrase at the left periphery of vP. The EP bears an Ellipsis-EPP (EEPP) feature, which must be satisfied. Maximal phrases in the c-command domain of EP are all potential candidates for satisfying the EEPP feature by moving to [Spec, EP]. However, only the phrases that are allowed to move out of vP can move to [Spec, EP] as EP is located above vP. Moreover, the movement to [Spec, EP] is subject to the syntactic and semantic restrictions in structure-building in that ellipsis is one operation in the course of structure-building and the derivation will continue after ellipsis takes place. The EEPP feature renders an XP in the specifier phonetically empty and syntactically frozen; therefore, a constituent will be deleted as soon as it moves to [Spec, EP]. The Hypothesis is schematically represented below. The Ellipsis EPP Hypothesis adequately accounts for the ellipsis of various vP-internal constituents - NPs, DPs, infinitive complements and CP complements - in both Mandarin and Xhosa. At the same time, it reveals the reasons why vP is precluded from being elided in these two languages. In Mandarin vP moves to [Spec, AspPi] to check the uninterpretable [asp] feature and in Xhosa vP moves to [Spec, FocP] to realize the focus; consequently, vP may not move to [Spec, EP] for ellipsis.

- Description: Management of an engineering consultancy unit in the Eastern Cape Province is concerned about the costs incurred by project managers and specialist engineers pursuing tender opportunities that are not feasible. Annual losses in this unit due to unsuccessful tenders amounts to R2,5 million annually, which equates to about 12% of the revenue generated by the unit. The aim of the research study is to assist the consulting engineering firm by investigating and identifying the key determinants for making the decision of whether to bid on a particular tender opportunity. The study includes an assessment of relevant literature, academia and text to investigate key factors that could influence the decision to bid on tenders from which research questions and appropriate theories were drawn. Based on the research questions and theories that emanated from the literature, the study also includes the assessment of primary data through the administration of a structured questionnaire. The questionnaire is empirically analysed within the positivistic research paradigm through the use of descriptive and inferential statistics. Conclusions are drawn and recommendations are made based on the findings of the administered questionnaire.

- Description: Floods are natural phenomena that are of widespread interest to the scientific community, particularly in the context of understanding the impact of climate change as well as changing land use patterns and the security of infrastructure such as towns and roads. In northern KwaZulu-Natal, large flood events have been a reoccurring feature over the past century. The geographical position and extent of the region means that is affected by both inland and coastal weather phenomena, each with the potential to cause large flood events. While information pertaining to large floods in the region in the form of flow data is readily available, flow data is often incomplete and limited in terms of how far back in time the records extend. The Mfolozi River floodplain itself also houses a record of flood activity in the region in the form of sedimentary deposits, which have the potential to reveal flood activity over a much longer timescale, even when monitoring of flood activity in the region was not present. Establishing a link between the hydrological and sedimentary features of floods may be useful in establishing a record of flood activity extending beyond the limits of historical records. The aim of this project was to construct a record of major flood events on the Mfolozi River floodplain over the last century and determine their source. The first objective involved establishing the history of flood events in the Mfolozi River catchment utilising hydrological data recorded throughout the catchment. Thirty nine different large floods (defined as being over 800 m3.s-1) were recorded on the floodplain over the past century. The data also highlighted differences in the extent of known coastal and inland systems (tropical cyclones and cut-off lows respectively), allowing for inferences to be made about the area of the catchment most likely affected by each event; some flood events were identified as having mostly affected the upper reaches of the catchment, while others mostly affected the lower reaches, closer to the coast. The second objective was to identify the various physical, mineralogical and geochemical features of the sediment deposited on the Mfolozi floodplain. Multiple individual flood deposits were identified in the sedimentary record, with sediment tracing analysis providing insight into the source of the deposits within the catchment; no traces of igneous or metamorphic material could be found within the sediment. The source rocks were identified as mostly quartzite, with minor shale and sandstone deposits as well. This put the source of the sediment in the upper to middle reaches of the catchment. The sedimentary analysis was combined with the hydrological records to establish a chronology of flood events extending back to the 1960's. Unfortunately, this record could not be extended further due to the limited amount of sediment collected as well the limits of readily available analytical techniques; radionuclide dating methods were unsuccessful due to the low amounts of fallout radionuclides present in the sediment. The study has however successfully established a history of flood events in the region, as well as providing a link between the hydrological and sedimentary features of flood events that could potentially be useful for current and future research.

- Description: The aim of this study was to evaluate the efficiency and effectiveness of the Performance Management System, since its inception and to date, with regards to the advancement of organisational goals and objectives through employee development, as well as resource allocation for service delivery to the residents of the Amathole District Municipality (ADM). The concept of performance management is key for achieving organisational goals and objectives, since it seeks to develop employees by identifying areas of strengths and weakness. The study is based on the assumption that although municipalities are different, and their approach to performance management particularly individual performance differs. This study therefore is based on the assumption that, levels of poor service delivery, and the consequent service delivery protests experienced in the ADM, can be ascribed to a poor linkage between annual performance planning and the assessment of municipal officials. Annual organisational performance, and individual performance planning and output, is not commensurate. Furthermore, a lack of correlation between these variables has led to the poor implementation of basic services and good governance, which has resulted in low levels of citizen satisfaction with the ADM. The empirical survey and research methodology used in the study is described and explained and followed by the data collection in a form of questionnaires. The research findings from the empirical survey are then analysed and reported accordingly. Recommendations are presented in the last chapter based on the empirical survey findings through the respondent’s inputs in the questionnaire. Recommendations are therefore also presented on how Amathole District Municipality can improve its business to achieve the objectives performance management. The key recommendation that came from the study is that ADM planning should be executed in collaboration with other government departments, government agencies, municipalities, private sector and NGOs, in order to maximize chances of achieving effective and efficient service delivery in communities.

- Description: Cissampelos capensis L. f. (Menispermaceae) commonly known as “Mayisake” (Xhosa) and “Dawidjieswortel” (Afrikaans) is the most commonly used medicinal plant of the Menispermaceae family in South Africa. The rhizomes of Cissampelos capensis are the most used part of the plant to treat illnesses. This poses a threat to the ongoing conservation of this valuable endemic species. Thus, we studied the chemical variation and subsequently the bioactivity in the stems and rhizomes of Cissampelos capensis, the Eastern Cape medicinal plant, to suggest the possible use of the stems for medicinal purposes. We studied the variation in the chemical composition in the stems and the rhizomes by employing four different extraction methods; the methanolic-, non-polar-, alkaloidal- and Total Tertiary Alkaloidal (TTA) to extract compounds from Cissampelos capensis. Employing various chromatographic techniques, HPLC, NMR and LC/MS to investigate the chemical variation and the in vitro assays for the crude materials of the stems and rhizomes of Cissampelos capensis. We successfully documented a library of the phytochemicals content in Cissampelos capensis from three different regions in the Eastern Cape. We could profile different extraction methods, with the TTA extraction delivering the best comparative profile. Employing LC/MS and HPLC we identified eleven known alkaloidal compounds in the stems and rhizomes. We also isolated a known alkaloid, pronuciferine, from the TTA extract and a crystal structure of proto-quericitol from the methanolic extract, which was isolated for the first time from Cissampelos capensis. Preliminary in vitro results suggested anti-inflammatory activity in the methanolic extracts of the stems and rhizomes, while the TTA extracts showed some cytotoxicity. Finally, through analytical HPLC analysis this study found as high as 31% similarity between the chemical variation of the stems and rhizomes, but key alkaloids were not always present, indicating more work is needed before the stems can be recommended as a replacement for the rhizomes.

- Description: Cissampelos capensis L. f. (Menispermaceae) commonly known as “Mayisake” (Xhosa) and “Dawidjieswortel” (Afrikaans) is the most commonly used medicinal plant of the Menispermaceae family in South Africa. The rhizomes of Cissampelos capensis are the most used part of the plant to treat illnesses. This poses a threat to the ongoing conservation of this valuable endemic species. Thus, we studied the chemical variation and subsequently the bioactivity in the stems and rhizomes of Cissampelos capensis, the Eastern Cape medicinal plant, to suggest the possible use of the stems for medicinal purposes. We studied the variation in the chemical composition in the stems and the rhizomes by employing four different extraction methods; the methanolic-, non-polar-, alkaloidal- and Total Tertiary Alkaloidal (TTA) to extract compounds from Cissampelos capensis. Employing various chromatographic techniques, HPLC, NMR and LC/MS to investigate the chemical variation and the in vitro assays for the crude materials of the stems and rhizomes of Cissampelos capensis. We successfully documented a library of the phytochemicals content in Cissampelos capensis from three different regions in the Eastern Cape.

- Description: This research dissertation investigates the level of Reconstruction and Development Programme (RDP) housing delivery in Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province. The post-apartheid South African Constitution indicates that the provision of basic services like formal housing is a basic right for all South Africans. In Limpopo Province and in particular, Disteneng (Polokwane Extension 44) Township, Capricorn District, there is still massive shortage of Reconstruction and Development Programme (RDP) housing for the poor, despite funding being made to address this need. Millions of poor families are suffering and are still living in shacks in informal settlements. There is a backlog in the provisioning of RDP housing delivery. Low cost housing projects have been identified in Limpopo Province to address the RDP housing delivery backlog. It takes time to complete RDP houses and the communities become impatient and frustrated. The quality of completed houses is often perceived to be of unacceptable standards. This study investigates the level of RDP housing delivery in Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province. This study also identifies the challenges of RDP housing delivery experienced by Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province. Recommendations with the view of resolving problems pertaining to Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province are made. The findings from this research work identified significant challenges of RDP housing delivery experienced by Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province which needs to be addressed. In its contribution, this study made recommendations with the view of resolving problems pertaining to Disteneng (Polokwane Extension 44) Township, Capricorn District: Limpopo Province. This study in conclusion, emphasizes the need to address RDP housing backlogs and ensure that RDP houses are of good quality and that the government and all South Africans have to join hands and collectively address the problems of RDP housing delivery in South Africa.

- Description: An unprecedented increase in real commodity prices from 2002-2011 fuelled an intense debate as to the causes of the steep rise in prices and its possible implications for producers and consumers. On the one hand, the prolonged and dramatic rise in almost all commodity prices is attributed to growing demand from emerging market economies, supply shocks such as adverse weather conditions, export bans as well as other macroeconomic factors. Collectively these are known as the fundamental (demand and supply) factors. On the other hand, there is a growing body of evidence that suggests these fundamental factors alone are not sufficient enough to explain recent commodity price developments. It is noted that alongside changes in the fundamental factors, there was a major shift in trading activities on commodity derivative markets related to the increasing presence of financial investors, institutional investors and hedge funds. This had important effects, it is argued, on the microstructure of these markets and on price dynamics in a process termed “fmancialization”. Most of the empirical literature covers the period of rising commodity prices from 20022011. This study seeks to add to the existing literature by examining, in addition, the impact of financialization when commodity prices were falling from 2011-2015. Whereas the literature focuses mainly on the rise of agricultural commodity prices, the focus of this study is on metals, oil and bulk commodities (coal and iron ore). Two techniques are employed, namely the calculation of rolling correlations for futures and spot returns. Granger causality tests are then performed to examine the relationships between futures and spot prices. Rolling return correlations are calculated for i) different exchange- traded commodities and ii) exchange-traded commodities and bulk commodities not traded on exchanges. This is done to establish whether the increased correlations between different commodities found in the literature still hold now that commodity prices across all categories are falling. Granger causality tests are used in order to establish the link between the futures prices and spot prices both during the upswing period (2002-2011) and downswing period (2011-2015). It is found that rapidly growing indexed-based investment in commodity markets (financialization) during the upswing period is concurrent with increasingly correlated returns on the prices of unrelated commodities in both the futures and spot markets. These correlations decline during the period of falling commodity prices (2011-2015). This was a period in which the total amount of commodity assets under management fell sharply. This supports the a priori expectation that if the increased correlations of previously seemingly correlated and unrelated commodities during the upswing had been driven by financialization, the correlation would decline in the downturn. Granger causality results reveal statistically significant evidence of futures prices (returns) driving spot prices (returns) during the financialization period. However, post-financialization there is a shift to more bidirectional relationships. The study therefore concludes that, in addition to changing fundamental and macroeconomic factors, the financialization of commodity markets further drove the excessive and volatile price levels in commodity markets from 2002 to 2011.

- Description: Community engagement in South Africa is now recognised as an integral part of Higher Education Institutions’ (HEIs) educational system. The South African Council on Higher Education requires HEIs to become equitable institutions of higher learning, whereby the activities of the HEI are mutually beneficial for both learners and their communities. This entails that, community engagement activities undertaken by HEIs should be reciprocal in nature. The HEIs should help solve issues affecting their communities, whilst also gaining knowledge through experiential learning. One such way is through undertaking Information and Communication Technology for Development (ICT4D) projects in communities outside the physical boundaries of the HEI. Over the years, HEIs in South Africa have been involved in undertaking ICT4D projects aimed at benefiting their communities. This is because ICTs have the potential to improve and contribute to the development of individuals, businesses, and communities in various ways, be it socially or economically. However, the ICT4D projects have failed or partially succeeded to attain their goals. This study, thus proposes a model for HEI researchers for the successful implementation of ICT4D projects through application of community engagement principles. The proposed model was formulated using the case study approach. Four cases of ICT4D projects were used as sample to help identify factors required for the successful implementation of ICT4D projects by HEIs. Data was collected using semi structured interviews, observations and literature. The data was then analysed using cross case analysis in the form of themes. The findings were that operational community engagement policies, understanding user needs, creation of long term partnerships, synchronisation of timelines and monitoring and evaluation are vital for the successful implementation of ICT4D projects by HEI researchers in the communities.

Browsing as a demographic bottleneck in a semi-arid savanna: the effect of size and age on compensatory responses of Vachellia karroo seedlings after simulated herbivory

- Description: Savannas are characterised by a continuous grass layer with scattered trees at varying densities. This vegetation structure is determined by several interacting factors, including fire, herbivory, resource competition and atmospheric CO2 concentration. The preservation of savanna biomes is important and a shift towards a woody biome threatens savanna globally. Bush encroachment which describes the shift towards domination of savannas by C3 woody plants, is especially acute in southern Africa. In semi-arid rangelands, encroachment progresses to dense thickets dominated by thorny and unpalatable bushes and trees. There is evidence that bush encroachment is driven by a reduction in fire and browsing events as well as their interaction. Despite browsing having strong effects on African savannas its isolated role in maintaining tree-grass coexistence has not received as much attention as the role of fire. Therefore the overall aim of this study was to examine the effects of browsing on seedlings of a commonly encroaching species, Vachellia karroo. Browsing was hypothesized to be a demographic release bottleneck for bush encroachment in a semiarid (MAP ~550mm) savanna in the Eastern Cape of South Africa, where fire has been historically rare. In a single study I explored the fate of V. karroo seedlings (less than a year old) following browsing in sub canopy and inter canopy microhabitats. Additionally, I explored how the fate of a seedling changed under high and low tree cover. Firstly, I investigated the type, intensity and frequency of herbivory, from both small and large herbivores, which seedlings were subjected to. Results revealed that browsing was severe and frequent with the majority of seedlings browsed more than twice over a 12 month period. Large browsers such as kudu and impala caused high seedling mortality (46%) while smaller browsers such as invertebrates were more effective at suppressing growth. Microhabitat had little impact on seedling survival, but significantly influenced plant compensatory growth. Reduced seedling growth following browsing was observed in the sub-canopy in comparison to seedling growth in full sunlight in the intercanopy, suggesting V.karroo may be shade intolerant. Secondly, the effect of tree cover on browsed seedlings was determined by quantifying browsing frequency and intensity at high and low tree cover. No differences in browsing intensity and frequency were observed between high and low tree cover. However, high tree cover due to bush encroachment limited seedling above ground growth. The aim of the second study was to investigate how V.karroo survival and growth were influenced by its age and size following simulated browsing. I explored this aim through field and greenhouse experiments. I was particularly interested in testing how plant sensitivity to varying defoliation intensities of repeated browsing varied with plant age (known ages of 6, 12, 16 and 30 weeks). There were large differences in mortality between the different age groups. Furthermore, age interacted with repeated browsing and negatively influenced seedling survival and regrowth. Older seedlings (16 and 30 week old) had greater survival and higher browsing frequencies resulted in greater mortality and reduced growth. The threshold age after which seedlings become more tolerant to herbivory occurs at an age of 28 weeks. Seedlings less than six weeks old experiencing intense (100 % defoliation)browsing had a very low probability (33%) of survival following just a single defoliation. Interestingly, all 16 week old seedlings regrew most of their foliage following a moderate (50%) defoliation with some plants overcompensating for leaf loss. The field study revealed two distinct demographic stages based on age and size (seedlings< 9 mm and saplings >9 mm in stem basal diameter (SBD)). Browsing had a strong negative effect on seedlings, resulting in reduced investment in leaf biomass. These findings suggest plant size and age can be used as robust predictors of a plants vulnerability to browsing. An increase in tree cover requires successful transitions of seedlings to saplings (also known as release). The results of this study suggest that in semi-arid savannas, browsing can impact tree cover through imposing a release bottleneck for tree seedlings and to lesser extent saplings. By limiting tree growth plants are kept in a disturbance trap and will therefore be exposed to not only browsers but fire. These findings also have important implications for tree-grass coexistence dynamics, suggesting that specific size and browsing thresholds should be considered in savanna management.

- Description: Important to the evaluation of potential feed ingredients for inclusion in fish diets should be their digestibility and amino acid requirement so that feeds can be formulated on a digestible basis rather than a gross nutrient basis. This thesis established techniques for faecal collection, the validity of digestibility markers, it determined apparent digestibility coefficients for various novel feed ingredients, and it established the optimal lysine requirement for Argyrosomus japonicus, which was used to estimate each of the essential amino acid requirements by using the ideal protein concept. There were no significant differences in dry matter apparent digestibility coefficients when faeces were collected by stripping (77.0 %), dissection (80.1 %) or settlement (83.5 %). Faecal collection by the settlement method produced the most reliable digestibility data. Apparent digestibility coefficients for dry matter, crude protein and energy calculated using acid-insoluble ash were higher (84.0 %, 93.2 % and 93.0 %, respectively) than those using chromic oxide (55.7 %, 79.1 % and 78.2 %) and titanium dioxide (58.6 %, 79.7 % and 80.5 %). The magnitude of variation in digestibility coefficients obtained using acid-insoluble ash was always lower than that obtained with the other markers. Therefore, acid-insoluble ash was preferred as a dietary marker. Using the above protocol, protein and amino acid digestibility of some animal and plant protein ingredients were evaluated in a series of experiments. The first trial compared the apparent digestibility coefficients of some animal products included as single protein source in the test diets. Apparent protein digestibility values were 84.5 %, 83.8 %, 85.8 % and 83.1 % for fishmeal-prime, fishmeal-standard, poultry meal and pork meal, respectively. Apparent digestibility coefficients for poultry meal were comparable to those of fishmeal, which indicate its potential as a substitute for fishmeal in the diets of A. japonicus. The second trial determined the apparent coefficients of plant and animal protein sources included at 30 % into a practical reference diet (70 %). Apparent protein digestibility ranged from 92.4 % in sunflower meal to 85.5 % in corn gluten meal. Soybean meal is a promising feed ingredient in A. japonicus due to the high apparent digestibility of its protein (92.0 %) and essential amino acid digestibility (mean average 91.4 %). A fundamental assumption in fish feed formulation is that the digestibility of nutrients is additive, i.e., digestibility of a nutrient in one ingredient does not interact with the digestibility of the same nutrient in another ingredient. In the third trial, additivity of feed ingredients was tested using pork meal and poultry meal. The results indicate that the apparent digestibility coefficient of animal protein ingredients could be calculated from compound diets to accurately determine protein and amino acid digestibility in A. japonicus, and possibly other carnivorous fish species. Dietary essential amino acid requirements were determined for juvenile A. japonicus in two trials. A dose-response study was conducted using crystalline lysine to determine the optimal requirement of dietary lysine for A. japonicus. Optimal dietary lysine was estimated at 31.7 g kg-¹ dry diet, corresponding to 73.5 g kg-¹ of dietary protein, based on specific growth rate and broken-line segmented regression analyses. Dietary requirements for other essential amino acids ranged from 22 g kg-¹ (histidine) to 71 g kg-¹ (leucine) crude protein. The results of the present study provided a research tool that could be used to assess and verify the conclusions of earlier dietary work on A. japonicus and in further studies to develop least cost diet formulations for this species. The study also adds to the knowledge of the nutritional requirements of A. japonicus by providing information on the digestibility of plants and animal protein ingredients. It also contributes to future dietary research for this species because this study determines, for the first time, the most suitable methods for investigating the digestibility of raw materials for A. japonicus.

Apparent digestibility coefficients for poultry meal were comparable to those of fishmeal, which indicate its potential as a substitute for fishmeal in the diets of A. japonicus. The second trial determined the apparent coefficients of plant and animal protein sources included at 30 % into a practical reference diet (70 %). Apparent protein digestibility ranged from 92.4 % in sunflower meal to 85.5 % in corn gluten meal. Soybean meal is a promising feed ingredient in A. japonicus due to the high apparent digestibility of its protein (92.0 %) and essential amino acid digestibility (mean average 91.4 %). A fundamental assumption in fish feed formulation is that the digestibility of nutrients is additive, i.e., digestibility of a nutrient in one ingredient does not interact with the digestibility of the same nutrient in another ingredient. In the third trial, additivity of feed ingredients was tested using pork meal and poultry meal. The results indicate that the apparent digestibility coefficient of animal protein ingredients could be calculated from compound diets to accurately determine protein and amino acid digestibility in A. japonicus, and possibly other carnivorous fish species. Dietary essential amino acid requirements were determined for juvenile A. japonicus in two trials. A dose-response study was conducted using crystalline lysine to determine the optimal requirement of dietary lysine for A. japonicus. Optimal dietary lysine was estimated at 31.7 g kg-¹ dry diet, corresponding to 73.5 g kg-¹ of dietary protein, based on specific growth rate and broken-line segmented regression analyses. Dietary requirements for other essential amino acids ranged from 22 g kg-¹ (histidine) to 71 g kg-¹ (leucine) crude protein. The results of the present study provided a research tool that could be used to assess and verify the conclusions of earlier dietary work on A. japonicus and in further studies to develop least cost diet formulations for this species. The study also adds to the knowledge of the nutritional requirements of A. japonicus by providing information on the digestibility of plants and animal protein ingredients. It also contributes to future dietary research for this species because this study determines, for the first time, the most suitable methods for investigating the digestibility of raw materials for A. japonicus.

- Description: Climate change and renewable energy have recently become part of the school curriculum in South Africa. Many teachers at the secondary school level thus have to teach topics with which they are not (necessarily) familiar. The Centre for Renewable and Sustainable Energy Studies at Stellenbosch University has established a schools' programme to provide materials to aid the educators in the teaching of renewable energy topics. A research-based set of Learning Teaching Support Material (LTSM) was developed for high school educators. The learning material includes a DVD, PowerPoint presentations, posters, a teacher's manual, and assignments that can be used in different subjects. This study reports and reviews how teachers are currently using the material. Teacher accounts of materials use and evidence of learning in students work were solicited using an appreciative inquiry review process. The data reflected the value being created through patterns of materials use. A Vygotskian based task sequencing framework of Anne Edwards was used to examine the patterns of use which support learning. The use of the task sequencing as an analytical lens allowed the review to probe how knowledge representation was the primary use by teachers. Here they introduced learners to key concepts and to broaden their knowledge on renewable energy. The activities served to scaffold a clear learning progression but the activities were not strongly enough orientated towards ESD as learner-led processes of enquiry and action. The outcomes of the study will be used to update and better align the materials with a need for teachers to strengthen important ESD outcomes in the current curriculum.

- Description: The principal aim of this study was to assess the socio-economic contribution of nontimber forest product (NTFP) trade to households in Zomba and Machinga, southern Malawi. Quantitative and qualitative data were collected through several methods, including a household survey using questionnaire interviews, focus group discussions, key informant interviews with individual traders, direct observations, and literature review. The quantitative data were analysed statistically using SPPS version 16.0 while the qualitative data were analysed thematically. NTFP trade was the third important source of cash income for 15% of the households, although the level of use, buying and selling of NTFPs varied across the four study villages. All households in all the study villages used firewood (100%), and most used thatch grass (94%), bamboo (96%), wood for building (92%), largely as construction materials. However, the percentage of households buying NTFPs was lower, with the maximum percentage of households being 50%. The percent of households engaged in selling at least one NTFP was lower still at 39%. Substantial cash incomes were generated from firewood and edible orchids sales which provided up to a maximum of Mk180,000, equivalent to US$456, per year. Households joined the trade mostly for an alternative source of cash income due to poverty and to meet basic needs when other options were not available or feasible. Cash income generated from NTFP trade acted as a safety net and a coping strategy when other avenues supporting livelihoods were not accessible. The socio-economic benefits derived from NTFP trade were associated with the quantities collected, sold, market forces influenced by the law of demand and supply. The small amounts of cash income generated by most households were important as they supplemented household cash needs. There was a strong association between NTFP trade as one of the important sources of cash income and the number of months a household had food from their own garden in a year. There was a significant relationship though weak between ranking of NTFP trade and livestock ownership by households. Value chain analysis was used as an analytical tool to understand the processes involved in NTFP trade. The value chains for the products under study were short, dominated by traders and some intermediaries. Most of the products were sold in local markets with little value addition. This study recommends that policy makers should integrate NTFPs into their development plans, emphasizing the establishment of management strategies that will enhance availability and sustainability of the resource. NTFPs contributed to the livelihoods of the households socially and economically through provision of food, cash income, energy for cooking, medicine and construction materials.

- Description: The use of radio and associated information and communications technologies (ICTs) has not been widely explored as a process of environmental education over the years. If environmental education is to involve many people, the use of radio and associated ICTs, particularly in community radio, needs to be researched because radio has multilayered functions. This study examines how practitioners in an agricultural Community of Practice (CoP), namely the Imvotho Bubomi Learning Network in the Nkonkobe Municipality, Eastern Cape, South Africa developed a radio programme on rainwater harvesting for the promotion of food security. The study probes the expansion and social learning of the network and into the public sphere after broadcasts. The study draws on research data generated in the Amanzi for Food project which was funded by the Water Research Commission of South Africa and was led by the Rhodes University Environmental Learning Research Centre. Using interviews, radio programme transcripts and observations, the study found that through using their prior knowledge from a training of trainers’ course on rain water harvesting and drawing on everyday experience of rainwater harvesting the CoP members had an expansion in their mutual engagement, joint enterprise, diversity, shared repertoire and identity into a knowledge community. This learning process developed through a successive elaboration of social ecological and social articulations related to the expansive functioning of the CoP; and experience of the benefits of rainwater harvesting as radio programme listeners deliberated how the different practices related to their existing knowledge and experience. The study also found that these expansive processes of social learning occurred across the spectrum of smallholder farmers and homestead food growers in a stimulated radio listening focus group discussion. The study concludes that agriculture practitioners involved in education for sustainable development could expand their knowledge sharing platforms by giving more attention to community radio as a means of both involving participants and engaging learning communities in local environment and sustainability concerns.

- Description: The purpose of this study was to evaluate how Phase 1 of the National Health Insurance Policy in South Africa was implemented. This evaluation focused on evaluation of reengineering of the primary health care system which is listed as one of the areas that was highlighted by the Department as needing attention during the implementation of Phase 1 of NHI. Reengineering of Primary Health Care was pronounced as the heart-beat of NHI. This is the approach that South Africa chose to implement to strengthen the current health care system. Specific measures that were selected to strengthen the current health system would be prioritized in Phase 1. Re-engineering of Primary Health Care is trusted with making a contribution to creation of a unified health care system. These areas would assist to close gaps which are a result of the current fragmented health care system. Inherited from the apartheid government of South Africa the current health care system has two fragments. One fragment is a highly resourced private health sector which provides quality health care for only 16 percent of the population while leaving 84percent of South Africans to access health care from the under-resourced public health sector. Fragmentation has contributed to inefficiencies in provision of health care. Post 1994 the Constitution outlawed discrimination based on economic and socioeconomic status which paved a way for progressive provision of universal coverage. To operationalize provisions of the Constitution of South Africa, the democratic government is implementing NHI which is a United Nations programme. To achieve a sustainable NHI, Phase 1 implementation also focused on strengthening the current health system. Through phased NHI implementation health financing reforms will become a reality. South Africa is implementing National Health Insurance policy to strategically redress health care financing which has resulted into an unequally fragmented health system. The end of a fragmented health system will give way to the birth of an ideal unified health system and universal coverage. The aim of this study was to evaluate how Phase 1 of National Health Insurance was implemented. Document method was used to collect documents, select and analyze data. This evaluation complements other studies which have contributed to the body of knowledge about implementation of programmes which will bring about realization of universal coverage.

- Description: Dance has numerous benefits for emotional well-being. For young people specifically it can serve as a prosocial activity where they can engage in a purposeful activity, in a safe space with consistent boundaries and discipline, while surrounded by peers, teachers and positive role models. Recreational spaces that allow young people to feel safe and express themselves is especially important in low socioeconomic areas where there are limited resources and exposure to heightened levels of crime as young people may be less likely to engage in negative behaviours when they have access to alternative, positive activities. This research aimed to explore the lived experiences of a group of young people who participate in dance classes at a community dance project in the Western Cape. The sample group consisted of four young people between the ages of 16 and 20. Semi-structured interviews were conducted with the participants and the interviews were analysed using interpretative phenomenological analysis. Three major themes emerged from the data, namely 1) My exposure to dance - The impact of context, 2) What motivates me to continue attending classes - The fulfilment of the three basic psychological needs, and 3) How does dance make me feel - The experience of emotional well-being through dance. The discussion of the findings yielded many similarities between the experiences of the participants and the relevant literature. Further, it appears that all four participants experience the satisfaction of the three basic psychological needs (competence, autonomy and relatedness) at the centre. This may serve as a motivator to continue attending classes as well as contribute to sustained eudaimonic wellbeing. Recommendations include further studies being conducted with groups of young people engaging in dance projects in different socioeconomic contexts and in different parts of South Africa. This could give us a more rounded understanding of how people young people experience dance class and how it contributes to emotional well-being. Further research could also be conducted with recreational projects that offer other activities in under-resourced areas in order to better inform the development of such recreational activities.

- Description: This treatise tests the effectiveness of withholding taxes imposed by the South African tax authorities with respect to amounts paid from a South African source to a non-resident in respect of interest, royalties and foreign entertainers and sportspersons. The first research objective discusses the alignment of the meaning of words and phrases in both the domestic law of South Africa and Double Tax Agreements (DTA.) The second issue outlines whether the DTA supports the domestic law through the waiving of tax claims in favour of the country of source. In last instance the attribution of income is discussed. The interpretation attached to the words for the purpose of levying normal tax, serves as the methodology for identifying inconsistencies with the levying of withholding tax. The wider scope of withholding taxes with respect to the meaning of ‘interest’, ‘royalties’ as well as ‘foreign entertainer and sportsperson’ misaligns with the corresponding meaning of it in the DTA. This creates the risk that amounts paid to non-residents will either not be subjected to withholding tax in the source state or that the income will be taxable in the resident state as a result of the application of other articles of the DTA. DTA’s concluded between South Africa and other countries are based on the OECD Model Tax Convention. These DTA’s tend to favour the residence state with respect to the waiving of tax claims. The source state’s right to collect withholding tax on income from royalties and interest is prevented if the foreign person is physically present in South Africa for more than 183 days and if the interest/royalty payment is effectively connected with a permanent establishment in South Africa. The domestic law and DTA are misaligned with respect to the attribution of interest and royalty income since the recipient of the income for the purpose of the domestic law is not necessarily the beneficial owner of the debt claim or intellectual property. It can therefore be recommended that South Africa must renegotiate DTA’s to favour taxation in the source state. Withholding tax provisions must also be redrafted to align them with the DTA meaning.

- Description: Marine top predators often occupy broad geographical ranges that encompass varied habitats. Therefore, a pre-requisite towards conserving these animals is to determine the components of their realized niche, and investigate whether a species is a specialist or a generalist. For generalist species, it is also necessary to understand if local specialisation occurs. Uncovering these components can allow us to build models of a species realized niche that may then be used to infer habitat use in unsampled locations. However, fully understanding the components of a marine top predators realized niche is challenging owing to the limited opportunity for in situ observations. Overcoming these limitations is a key step in marine top predator research. It will enhance our understanding of trophic coupling in marine systems, and aid in the development of tools to better study these predators in their dynamic environment. Seabirds, penguins (Spheniscids) in particular, are a group of animals for which investigating their realized niche is of vital importance. This is because numerous species face growing uncertainty in the Anthropocene, and in a time of rapid environmental change there is furthermore a need to better understand the potential use of these birds as indicators of ecosystem health. The aim of this thesis, therefore, is to investigate the foraging ecology of gentoo penguins (Pygoscelis papua) at the Falkland Islands. At the Falkland Islands, limited historical information exists regarding this species foraging ecology, with most information coming from a single location at the Falklands. As the Falkland Islands have the world’s largest population of gentoo penguins, elucidating factors influencing this population will have global relevance. Furthermore, historical information indicated potential competition with fisheries, and with prospecting for hydrocarbons and an inshore fishery, there is a need to understand the distribution of these birds across the islands. Penguins are also well suited to carry biologging devices allowing for in situ observations of inter and intraspecific interactions, as well as habitat specific interactions. In this study, I sampled birds over three breeding seasons, from four breeding colonies - chosen for their varied surrounding at sea habitat - across the Falkland Islands. I investigated the diet with stomach content and stable isotope analysis, the at-sea distribution with GPS and time depth recorders, and how these birds behaved at sea using custom made animal-borne camera loggers. Furthermore, I developed a method to recognise prey encounter events from back mounted accelerometers, using a supervised machine learning approach. As part of the first species specific description of diet at this scale for the Falklands, I revealed six key prey items for the birds: rock cod (Patagonotothen spp.), lobster krill (Munida spp.), Falkland herring (Sprattus fuegensis), Patagonian squid (Doryteuthis gahi), juvenile fish (likely all nototheniids), and southern blue whiting (Micromesistius australis). The use of animal-borne camera loggers verified that not only do gentoo penguins consume a diverse array of prey items, but they adopted various methods to capture and pursue prey, with evidence of birds following optimal foraging theory. Prey composition varied significantly between study sites with the at-sea distribution and habitat use of penguins reflecting that of local prey. Birds from colonies close to gently sloping, shallow waters, foraged primarily in a benthic manner and had larger niche widths. However, those at a colony surrounded by steeply sloping, deeper waters, typically foraged in a pelagic manner. Contrasting diet patterns were also prevalent from stable isotope data, and the niche widths of birds relating to both stomach content and stable isotope data were larger at colonies where benthic foraging was prevalent. Therefore, it was clear that surrounding bathymetry played a key role in shaping this species’ foraging ecology, and that at the population level at the Falkland Islands birds are generalists. However, at individual colonies some specialisation occurs to take advantage of locally available prey. I developed habitat distribution models - via boosted regression trees – which transferred well in time but poorly across space. Reasons for poor model transfer might relate to the generalist foraging nature of these birds and the reduced availability of environmental predictors owing to the limited range of these birds. I furthermore developed a method to identify prey encounter events that can also, to a degree, distinguish between prey items. This method will be a promising approach to refine habitat distribution models in future. These habitat distribution models could potentially contribute to marine spatial planning at the Falkland Islands. Footage from animal-borne camera loggers clearly showed that prey behaviour can significantly influence trophic coupling in marine systems and should be accounted for in studies using marine top predators as samplers of mid to lower trophic level species. Ultimately, flexibility in foraging strategies and inter-colony variation will play a critical role when assessing factors such as interspecific competition or overlap with anthropogenic activities.

- Description: Marine top predators often occupy broad geographical ranges that encompass varied habitats. Therefore, a pre-requisite towards conserving these animals is to determine the components of their realized niche, and investigate whether a species is a specialist or a generalist. For generalist species, it is also necessary to understand if local specialisation occurs. Uncovering these components can allow us to build models of a species realized niche that may then be used to infer habitat use in unsampled locations. However, fully understanding the components of a marine top predators realized niche is challenging owing to the limited opportunity for in situ observations. Overcoming these limitations is a key step in marine top predator research. It will enhance our understanding of trophic coupling in marine systems, and aid in the development of tools to better study these predators in their dynamic environment. Seabirds, penguins (Spheniscids) in particular, are a group of animals for which investigating their realized niche is of vital importance. This is because numerous species face growing uncertainty in the Anthropocene, and in a time of rapid environmental change there is furthermore a need to better understand the potential use of these birds as indicators of ecosystem health. The aim of this thesis, therefore, is to investigate the foraging ecology of gentoo penguins (Pygoscelis papua) at the Falkland Islands. At the Falkland Islands, limited historical information exists regarding this species foraging ecology, with most information coming from a single location at the Falklands. As the Falkland Islands have the world’s largest population of gentoo penguins, elucidating factors influencing this population will have global relevance. Furthermore, historical information indicated potential competition with fisheries, and with prospecting for hydrocarbons and an inshore fishery, there is a need to understand the distribution of these birds across the islands. Penguins are also well suited to carry biologging devices allowing for in situ observations of inter and intraspecific interactions, as well as habitat specific interactions. In this study, I sampled birds over three breeding seasons, from four breeding colonies - chosen for their varied surrounding at sea habitat - across the Falkland Islands. I investigated the diet with stomach content and stable isotope analysis, the at-sea distribution with GPS and time depth recorders, and how these birds behaved at sea using custom made animal-borne camera loggers. Furthermore, I developed a method to recognise prey encounter events from back mounted accelerometers, using a supervised machine learning approach. As part of the first species specific description of diet at this scale for the Falklands, I revealed six key prey items for the birds: rock cod (Patagonotothen spp.), lobster krill (Munida spp.), Falkland herring (Sprattus fuegensis), Patagonian squid (Doryteuthis gahi), juvenile fish (likely all nototheniids), and southern blue whiting (Micromesistius australis). The use of animal-borne camera loggers verified that not only do gentoo penguins consume a diverse array of prey items, but they adopted various methods to capture and pursue prey, with evidence of birds following optimal foraging theory.
