- Description: This study investigated whether there was correlation in study habits and learning styles with Mathematical Literacy among the Grade 11 (eleven) high school learners. The Amatole Education District was chosen for this study since it is composed of urban and rural schools. Since Mathematical Literacy was introduced in the system of education in South Africa with the understanding that learners who are finding it a challenge to study Mathematics be complemented with Mathematical Literacy to provide them with skills that are a prerequisite for tertiary level and participation in the economic development. The study purposed to establish whether there was a relationship between academic performance with study habits and learning styles in Mathematical Literacy. The study used the post-positivistic paradigm; the approach was quantitative and the design was descriptive correlational. In sampling probability, cluster sampling was used based on the number of high schools in the Amatole Education District of the Eastern Cape. It was then followed by sub-sampling of learners in Grade 11 (eleven) whose mathematical Literacy skills and performance were being investigated in this study. The theory of Covey on study habits and Kolb’s theory on learning styles were used as a theoretical framework for the study. The data collection instrument used was a closed-ended questionnaire based on a Likert scale measurement. Confidentiality and anonymity were emphasized with informed consent in place. Data was analyzed using SPSS software and Microsoft Excel. The results showed a significant relationship between note taking, writing skills and Mathematical Literacy skills and performance. The findings on the learning styles indicated no significant relationship between socio-demographic factors (visual language, visual numerical, auditory-numerical e.tc.) and academic performance in Mathematical Literacy. This research revealed that study habits had an impact on the academic performance of learners in mathematical literacy. This relationship between academic performance and study habits is an indication that learners needed to improve in their use of English as a second language, especially on note taking, writing skills and Mathematical Literacy.

- Description: Estuaries are among the most productive ecosystems worldwide as they provide important refuge and feeding areas for the juveniles of many marine species, many of which have recreational importance. The use of these nursery areas by juvenile fishes in South Africa are in need of further investigation and many critical areas such as shallow water creeks and vegetated habitats remain understudied. By using mixed-methods, estuarine fish assemblages were assessed in five permanently open estuaries in the Eastern Cape Province of South Africa. A total of 81 428 comprising 24 families and 40 species of fishes were sampled by means of a 50 m seine net (12 mm mesh) along the length of these systems that comprised of six equidistant sites during the summer recruitment period (October - December) of 2014 and 2015. A higher catch per unit effort (CPUE) was recorded in 2014 (68 875) compared to the following year where a decline of approximately 82% was observed in the catch (12 553) for all estuaries except the Kromme Estuary. Catches were mainly dominated by the marine estuarine dependent sparid, Rhabdosargus holubi and the solely estuarine clupeid, Gilchristella aestuaria. Species compositions and catch abundance with regards to historical catches showed that the abundance of many marine estuarine dependent juveniles as well as important recreational species have declined within these systems and are mainly attributed to marine overfishing and the exploitation of undersized individuals in estuarine nurseries. Juvenile fishes that occur in these estuaries utilize a range of vegetated habitats ranging from salt marsh creeks, Zostera capensis beds, Spartina maritima and previously unexplored Phragmites australis areas. Sampling was achieved by using passive, double-winged, six-hooped fyke nets, 1 mm mesh size that was secured in placed on the nocturnal flood tide at each inundated vegetated and adjacent unvegetated habitat types. Higher catches were frequently recorded in vegetated areas for solely estuarine and marine estuarine dependent species and supports evidence of plasticity within these habitats. In general, the previously unstudied reed, P. australis showed the highest species richness and abundance of juvenile fishes overall, followed by, Z. capensis and the intertidal salt marsh species, S. maritima. These findings relate to many international trends on the value of vegetated areas as refugia for young fishes in estuaries. Fishes were also showing evidence of feeding and sheltering in these areas. By using conventional stomach contents and stable isotope methods (δ13C and δ15N signatures) on the abundant R. holubi in previously selected vegetation sites, it was clear that this species has a significant reliance on any of these habitats as their diets was largely comprised of a mixture of epiphytic algae and aquatic macrophytes. In addition, the diet of larger individuals (>80 mm) showed a greater component of invertebrates in previously unexplored habitats, which proves their omnivorous diet related to ontogenetic niche use. Knowledge of fine-scale habitat use by fishes is essential for conservation planning as exclusion zones can be optimised to limit anthropogenic influence on nursery use patterns in fishes. The availability of shallow water habitats (<60 cm) was assessed as an additional driver to explain the species diversity and richness of juvenile fishes within the lower reaches. These habitats are known as important nursery habitats providing numerous marine and estuarine spawned fishes with adequate refuge and food supply. This shallow water volume was measured by means of a two-man kayak using both the spring high and low tides in the lower reaches of these systems to assess juvenile assemblages. It was clear from the results that aquatic vegetation significantly adds to the volume of these areas and as a result, much greater fish density and species richness were observed. Generalized additive models showed that marine spawned species were particularly reliant on the availability of this shallow water along with submerged vegetation and additional environmental variables. The presence of structurally submerged vegetation typically characterized within shallow estuarine waters is commonly believed to reduce predation risk resulting in elevated densities of biota. Based on the current stock status and percentage of pristine breeding stock, five fish species classified as collapsed/overexploited was consistently found within these systems with an additional 14 species currently classified as exploited/vulnerable. Based on the current species richness and diversity, available habitat cover and knowledge regarding important recreational species, priority areas that require some form of legal protection in order to meet potential biodiversity targets, could be identified. It is a legal requirement in South Africa that all estuaries require management plans that should be based on good knowledge of priority habitats for fauna and flora. The identification of estuarine protected areas is seen as a mechanism for protecting a representative sample of the biodiversity accompanied by a complete range of environmental gradients and habitat types at a reasonable scale in order to maximize the protection of estuarine species.

- Description: Cyanobacterial blooms are becoming more frequent worldwide, with possible negative effects on human health. The effects of climate change and eutrophication have been associated with persistent cyanobacterial blooms becoming more frequent. Altered water characteristics, salinity in particular, influence ecosystem dynamics that may lead to conditions conducive to cyanobacterial blooms. The occurrence of an 18-month long Cyanothece sp. bloom (the longest for any cyanobacterium recorded so far worldwide and the first of the genus) from June 2009 to December 2010 in Africa’s largest estuarine lake, St Lucia, highlighted the susceptibility of ecosystems to anthropogenic alterations. This study investigated the long-term survival and physiological adaptations of Cyanothece sp. to various and dynamic environmental conditions that contributed towards its bloom persistence. The main findings are the high salinities at which Cyanothece sp. could perform important physiological processes such as N uptake, N2 fixation and photosynthesis. Nutrient uptake (both nitrogen and phosphorus) was observed over the full experimental salinity range (0-300) while N2 fixation was only observed up to a salinity of 120. Nutrient uptake rates significantly decreased at this threshold salinity of 120. Interestingly, photosystem II activity was not observed in Cyanothece sp. during this study, but photosystem I activity was robust. Salinity had a minor influence on electron transport rates by photosystem I, high temperature (> 30°C) did however increase electron transport rates. Rapid responses to hypo-osmotic shock (i.e. osmotic downshift during freshening events) by Cyanothece sp. cells also helped minimize cell rupture due to high turgor pressure. Zooplankton abundance within the St Lucia system was negatively correlated with salinity, while grazing experiments indicated that the typical estuarine zooplankton species are able to graze on Cyanothece sp. cells. Therefore, the disappearance of zooplankton at salinities above 60 must have been an important factor in the bloom persistence. Apart from the ecological factors that were at play in St Lucia during the bloom period, the persistence of the Cyanothece sp. bloom can be attributed to the robust nature of their nutrient uptake, nitrogen fixation and photosynthetic systems to maintain activity despite extreme hypersalinity levels.

- Description: Cloud computing adoption and usage is important to achieving business competition. This is done by making it a competitive tool for firms. The adoption of cloud computing enables firms to achieve greater business competency, improve performance, and allows them to maintain their competitive advantage. Since its emergence, there has been a surge in the adoption of cloud computing with research into its adoption primarily concentrated on bigger firms. However, a major characteristic of cloud computing is the anticipated possibilities it holds for small and medium-sized enterprises (SMEs). SMEs typically operate differently from larger firms and are not limited by resource constraints. For SMEs, the reduction in the financial burden normally associated with the adoption of new technologies is a significant benefit of cloud computing due to their financial constraints. In Ghana, SMEs mostly use obsolete technologies and have a slow response towards new technologies. Thus, they are unable to harness the numerous opportunities technology presents to them to stay competitive. Cloud computing is still regarded as a new technology in the business world, therefore research that focuses on its adoption by SMEs to help them stay competitive is minimal. Available research on cloud computing in Ghana does not provide clear guidelines for ensuring a successful adoption process and the continued use of cloud computing services. This study seeks to investigate how a framework can assist SMEs in their use of cloud computing in the Accra-Tema metropolis of Ghana. A knowledge of the factors associated with adoption decisions and those that significantly influence the decision are required to ensure a successful adoption process. The empirical data was gathered using a questionnaire and face-to-face interviews developed from literature and administered to users and potential users of cloud computing. The questionnaire and interviews primarily investigate key adoption factors and the findings are reported in this research study. The findings reveal interesting insights into understanding issues that affect the overall decision to adopt and use cloud computing services by SMEs. The findings show that the adoption of cloud computing can improve information management practices within SMEs. The findings also reveal that several factors need to be considered in the overall decision to adopt and use cloud computing to ensure a successful adoption process. An initial cloud computing adoption model was proposed based on the empirical findings. Key adoption factors of the initial adoption model include adoption benefits and drivers, concerns and barriers, adoption interventions, and information management in the cloud. computing adoption framework. The proposed adoption framework aims to assist SMEs to adopt and use cloud computing services and make them relevant in the global market.

- Description: Songs play a vital role in the everyday life of the AmaXhosa. Each and every occasion or gathering is accompanied by singing. Their anger or pain, sorrow or joy is reflected in their singing. Although these songs are composed for social purposes and entertainment, they are also educational. Songs may be composed and sung to comment on political affairs, complain against the abuse of power by the authorities, declare war, protest, praise a hero, encourage working together and ridicule the foolishness of someone. Vocabulary and diction used in the composition of these songs, relays the message in a clever and witty style. Since the AmaXhosa are intellectuals, irony and satire are used. The satirical or ironical songs hide the meaning and the listener must unravel the real meaning. AmaXhosa singing, chanting and dancing is accompanied by instruments. These instruments add more rhythm to the dance.The AmaXhosa use anything at their disposal when carving their instruments. Their songs may be accompanied by the beating of cow-hide drums, blowing of reed-pipe whistles, animal horns, beating of sticks and hand-clapping. The most important instrument the AmaXhosa use is the human voice. They are experts in humming, gruff singing and whistling. The songs of the AmaXhosa encourage togetherness. When one composes a song, one does not express one’s own feelings, but also the feelings of the community. The AmaXhosa songs are about participation so group singing and dancing is encouraged. Everyone participates either by singing, dancing or clapping. x Respect is the central core of the AmaXhosa songs. That is why the songs are composed according to age groups and sex. Instruments are also used according to ages and sex. Written texts are also a tool to educate the reader. The writers have decided to include songs in their writings to act as a form of entertainment and education. Although some songs lack the hallmarks of a traditional song, they communicate the idea or relay the message the writer wants to convey to the reader. Terms: Mock enconuim, the grotesque and the principle of beautiful deformity, anaphoric construction, diction and connotation, authorial comments, the mask-persona form, usurping of authority and reduction of traditional status.

Whither South Africa – neoliberalism or an embodied communitarian indigenous ethic?

- Description: This thesis offers a critique of neoliberal transformation in South Africa, which process results in growing social inequality and political apathy among citizens. Many scholars have made political-economic and historical analyses of the neoliberal transition, emphasizing structural changes at work at a ‘macro’ level. However, little attention has been paid to changes that have taken place in South Africa at the ‘micro’ level – changes to individual subjectivity and gender codes. That said, the thesis opens by summarizing the above mentioned political-economic accounts of neoliberalism in South Africa, because such works are indispensable to understanding how the regime is embedded within and buttressed by major global institutions. Yet, to achieve a holistic grasp of ‘neoliberal South Africa,’ more is needed. A sociological investigation into the impact of neoliberalism on ordinary people’s self-identification uncovers deep cultural reasons for the continued perpetuation of this unjust political-economic system. Only if it can be understood why people comply with the system in the face of suffering, can effective counter-measures be proposed and implemented over time. This thesis is inherently transdisciplinary. The approach rejects the privileging of one discipline over others, and likewise cautions against collapsing or dissolving disciplines into one another. Instead, recognizing the valuable contribution that each discipline can make to critical scrutiny of a particular issue, a form of methodological transversalism is used to bring different disciplines into dialogue with one another. Following this interplay of structural and subjective analysis, the thesis uncovers the role that consumerism plays in the political neutralization of South Africans. Consumer culture, tied as it is to profitable accumulation, instigates the neoliberal ‘values’ of economistic calculation, competition, and social atomization. This ethos is inculcated in individuals, both at work and during leisure hours. Moreover, consumerism derives much of its power from its ‘sexual sell,’ the creation of fashionable and ‘exemplary’ models of masculinity and femininity. In South Africa, these hegemonic gender models serve to instill competitive individualism while derogating indigenous values. The thesis proposes that in order to counter neoliberal hegemony in South Africa, and begin reclaiming the cultural autonomy of its peoples, it is important to invigorate indigenous communitarian practices and norms. The original contribution of this thesis consists in placing the African ethos of ubuntu in transversal dialogue with global ecological feminist voices. Both political perspectives reinforce a liberatory alternative vision for a future based on principles of embodied relationality, care giving and protection of community.

Instead, recognizing the valuable contribution that each discipline can make to critical scrutiny of a particular issue, a form of methodological transversalism is used to bring different disciplines into dialogue with one another. Following this interplay of structural and subjective analysis, the thesis uncovers the role that consumerism plays in the political neutralization of South Africans. Consumer culture, tied as it is to profitable accumulation, instigates the neoliberal ‘values’ of economistic calculation, competition, and social atomization. This ethos is inculcated in individuals, both at work and during leisure hours. Moreover, consumerism derives much of its power from its ‘sexual sell,’ the creation of fashionable and ‘exemplary’ models of masculinity and femininity. In South Africa, these hegemonic gender models serve to instill competitive individualism while derogating indigenous values. The thesis proposes that in order to counter neoliberal hegemony in South Africa, and begin reclaiming the cultural autonomy of its peoples, it is important to invigorate indigenous communitarian practices and norms. The original contribution of this thesis consists in placing the African ethos of ubuntu in transversal dialogue with global ecological feminist voices. Both political perspectives reinforce a liberatory alternative vision for a future based on principles of embodied relationality, care giving and protection of community.

- Description: This thesis focuses on the developmental impact of rural-urban migration in Nigeria. While, recognising the negative impact of rural-urban migration, the study argues that in order to benefit internal migrants as well as rural development, there must be a paradigm shift to focus on how the benefits of migration on development can be achieved. It is proposed that rural-urban migration occurs as a response to economic, education, health, social and environmental factors. The challenges confronting rural areas are urban bias development paradigm pursued by the successive governments resulting in rural underdevelopment that exacerbates the rural urban disparity. And the neglect of agriculture in rural areas resulting from the discovery of oil in Nigeria. The study revealed that flawed policies adopted by successive Nigerian governments led to joblessness, entrenched social inequality and opportunities. One of the outcomes of these short-sighted policies was rural underdevelopment, which accelerated rural-urban migration in Nigeria. However, the study also demonstrates that the income flows from the migrants to the various rural households has contributed to improvement in the living standard of the households. The fragmentary approaches to rural development that is currently the case in Nigeria would not generate the required level of development and growth needed in the rural communities to improve the living standard. Thus, there is need for a policy framework in Nigeria, which would encourage the private sector to play a vital role in contributing their part in the provision of infrastructural facilities in the rural communities. Although this thesis is a case study of the impact of rural-urban migration on rural development in Nigeria, it can serve to appreciate the role migration can play in promoting development both in rural and urban areas in Nigeria and other Saharan Africa countries.

- Description: The popularity of mobile technologies has greatly influenced the people of all ages, especially adolescents. Tablet computers as part of mobile technologies, were launched in colleges and universities in many countries to supplement and complement learning and teaching. However, research reports based on the effectiveness of the use of tablet computers in higher education institutions in South Africa’s Eastern Cape Province are scarce. In order to address the deficiency, this study examined the views of stakeholders such as students, lecturers and managers on the use of tablet computers for learning and teaching in one of the Eastern Cape universities. The research adopted the Post-Positivist paradigm and mixed method approach. The theoretical frameworks were Constructivism and Technological Pedagogical Content Knowledge. The sample consisted of (a) 155 students from a population of 254 extended-stream National Diploma students in Information and Communication Technology and National Diploma Electrical Engineering cohorts; (b) 14 lecturers from a relevant population of 25; and, (c) 16 managers from a population of 20. Three separate questionnaires as well as interview protocols for each of the stakeholder cohorts provided the core data. All members in the sample were surveyed. The researcher opted to be an outsider and received assistance from a few qualified trained academics to administer the questionnaire to students in different cohorts in order to minimise data bias. Only 18 students, five lecturers and nine managers were interviewed. Quantitative data were captured manually into Statistical Package for Social Sciences (version 24) and they were analysed using descriptive and inferential analysis: Analysis of Variance and Independent Samples t-test. Qualitative data were transcribed and analysed using thematic analysis to generate major themes and sub themes for the sub-research questions. Main strengths of using tablets from the findings of the study were (a) tablets motivated students in learning and lecturers in teaching (b) students understood the different styles of learning (c) enhanced students’ engagement and collaboration in learning. Main weakness of using tablets were students’ use of tablets for personal work and social networking during class hours was causing distractions to lecturers and other students. Generally, the evidence shows that strengths were greater than the weaknesses. It should also be noted that all stakeholders were positive and not statistically significantly different from each other in their views towards the use of tablets for learning and teaching in university classroom. However, students had views different from lecturers on the advantages and disadvantages of using tablets. The variance could be due to new students or new lecturers’ ignorance in the effective use of tablets and this might change as their familiarity in the use of the device improves. The research report makes a few recommendations which include training to all students and lecturers on the effective use of tablet computers for learning and teaching and installation of relevant applications before the commencement of each academic year. Moreover, the Information and communication technology technical staff must prevent students from visiting unwanted and restricted sites by keeping a network based tracker and blocker software application.

- Description: A study of the available literature on Workplace Well-being, Positive Organisational Capital and Workplace Trust revealed that enormous potential existed for further research. This is a relatively new field with limited literature and research evidence available. It became very clear from the beginning that the relationships between these constructs could successfully be researched. It was therefore decided to embark on an academic research journey in order to contribute to the existing knowledge available on these constructs within the South African business scenario. This quantitative research was used to obtain more clarity about the relationships between the three constructs and to gather the responses from the research population. This research group consisted of 228 managers from the manufacturing operation of a motor vehicle production company and 224 managers from their National Dealership network. The research sample consisted of 452 managers. Three questionnaires were integrated to develop the composite Workplace Wellbeing Questionnaire and consisted of i) Workplace Well-being questionnaire developed by Parker and Hyett (2011), ii) PSYCAP Questionnaire developed by Luthans, Youssef and Avolio (2007), and iii) Workplace Trust Survey developed by Ferres (2001). The managers (n = 452) responded to a 91–item electronic questionnaire. Seven research questions were formulated and covered areas such as: The content, validity and portability of the measuring instruments; The configuration of the various constructs; Relationships between some of the variables; The effect of demographical data on the research variables and; The building of a research model. The content and the structure of the measuring instruments were assessed by means of Confirmatory Factor Analysis (CFA) and Exploratory Factor Analyses (EFA). These assessments showed that the original measuring instruments are not portable to a culture which is different to the one where they were originally developed. The relationships between the variables were determined by: Pearson product moment correlation; Multiple Regression co-efficient; ANOVA and Cohen’s d Test. The relationship between aspects of Workplace Well-being (Job satisfaction) and trust is a significant finding; so are some aspects of PSYCAP (sense of achievement and optimism) and Trust and Well-being. Trust has shown a definite relationship with Work- place well-being. A structural equation model was built to test the relationships between the elements of Workplace Well-being, PSYCAP and Workplace Trust. No satisfactory fit of the model on the data was obtained, although strong correlations between some of the variables existed. The significance of the findings of this study and the contribution that it makes to the existing theory is seen in the importance of the portability of measuring instruments. Recommendations in this regard have been made in Chapter 5. Various findings have also highlighted the relationships between Workplace Well-being, PSYCAP and Work-place Trust. The importance of future research topics has been recommended and a proposal has been made to consider a longitudinal well-being research study.

- Description: In South Africa mangrove forests are located in estuaries from Kosi Bay in KwaZulu-Natal (KZN) to Nahoon Estuary in the Eastern Cape. The aims of this study were to determine the present state of mangroves in KwaZulu-Natal, by assessing the current population structure, the changes in cover over time and associated anthropogenic pressures. A second objective of this study was to determine the effect of harvesting on the population structure and sediment characteristics in the Mngazana mangrove forest. To determine if harvesting was sustainable at Mngazana Estuary; the growth and mortality rates and associated growth conditions were measured. Finally by using population modelling sustainable harvesting limits were determined by predicting the change in population structure over time. The study focussed on the KwaZulu-Natal province as a fairly recent study addressed mangrove distribution and status in the Eastern Cape Province. A historical assessment of all mangroves forests in KwaZulu-Natal (KZN) revealed that the potential threats to mangroves in South Africa include; wood harvesting, altered water flow patterns coupled with salinity changes, prolonged closed-mouth conditions and subsequent changes to the intertidal habitat. As a result mangroves were completely lost from eleven estuaries in KZN between 1982 and 1999 and a further two estuaries by 2006. Mangroves only occurred in those estuaries where the mouth was open for more than 56 percent of the time with the exception of St Lucia, where the mouth has been closed for longer but the mangrove communities have persisted because the roots of the trees were not submerged. All mangrove forests in KZN were regenerating in terms of population structure as they had reverse J-shaped population curves as well as high adult: seedling ratios. Kosi Bay and Mhlathuze Estuary were two of the larger forests that showed signs of harvesting (presence of tree or branch stumps), but the greatest threat to smaller estuaries seems to be altered water flow patterns due to freshwater abstraction in the catchments and the change of land use from natural vegetation to sugar-cane plantations. These threats affect the hydrology of estuaries and the sediment characteristics (particle size, redox, pH, salinity, temperature) of the mangrove forests. The environmental conditions under which the mangrove forests currently exist were determined for five species. Lumnitzera racemosa and Ceriops tagal exhibited a narrow range of conditions as these species are only found at Kosi Bay, while Avicennia marina, Bruguiera gymnorrhiza and Rhizophora mucronata were found to exist under a wider range of conditions. The growth rate and response to environmental conditions of the three dominant species were important to determine as these species are impacted by harvesting. Mangrove growth rates were measured at Mngazana Estuary in the Eastern Cape, the third largest mangrove forest in South Africa. Areas of this estuary where mangroves harvesting has occurred, show significant differences in sediment characteristics as well as changes in population structure in harvested compared to non harvested sites. The growth rate (in terms of height) of Avicennia marina individuals increased from seedlings (0.31 cm month-1) to adults (1.2 cm month-1), while the growth of Bruguiera gymnorrhiza stabilised from a height of 150 cm at 0.65 cm month-1. The growth of Rhizophora mucronata peaked at 0.72 cm month-1 (height 151-250 cm) and then decreased to 0.4 cm month-1 for taller individuals. Increases in diameter at breast height (DBH) ranged between 0.7 and 2.3 mm month-1 for all species. Some environmental variables were found to be important drivers of growth and mortality of individuals less then 150 cm. A decrease in sediment pH significantly increased the mortality of Avicennia marina seedlings (0-50 cm) (r = - 0.71, p<0.05) and significantly decreased the growth of Rhizophora mucronata and Bruguiera gymnorrhiza seedlings (r = -0.8, r = 0.52 – p < 0.05 respectively). At Mngazana Estuary, mortality of this species showed a positive correlation with sediment moisture content indicating that this species prefers drier conditions. The density of Rhizophora mucronata was significantly correlated to porewater temperature in Northern KZN as was the growth of adult (>300 cm) Rhizophora trees at Mngazana Estuary. Mortality of Avicennia marina individuals (51-150 cm) was related to tree density indicating intraspecific competition and self thinning. Selective harvesting of particular size classes of Rhizophora mucronata was recorded when comparing length of harvested poles (~301 cm) and the size class distribution of individuals. Taking into account the differences in growth rate for each size class for this species it will take approximately 13 years to attain a height of 390 cm which is the height at which trees are selected for harvesting at this estuary. This is 2.6 times slower than those individuals growing in Kenya. The feasibility of harvesting is dependent on the growth rate of younger size classes to replace harvested trees as well as the rate of natural recruitment feeding into the population. Different harvesting intensity scenarios tested within a matrix model framework showed that limits should be set at 5 percent trees ha-1 year-1 to maintain seedling density at > 5 000 ha-1 for R. mucronata. However harvesting of Bruguiera gymnorrhiza should be stopped due to the low density of this species at Mngazana Estuary. Harvesting of the tallest trees of Avicennia marina can be maintained at levels less than 10 percent ha-1 year-1. Effective management of mangrove forests in South African is important to maintain the current state, function and diversity of these ecosystems. Management recommendations should begin with determining the freshwater requirements of the estuaries to maintain the mouth dynamics and biotic communities and deter the harvesting of (whole) adult trees particularly those species that do not coppice. Further management is needed to ensure that forests are cleared of pollutants (plastic and industrial), and any further developments near the mangroves should be minimized.

- Description: The human immunodeficiency virus / acquired immune deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. There is a concurrent and distinct increase in the prevalence of HIV/AIDS and HIV-related diseases in the paediatric population in South Africa, particularly those using public sector health services, with a corresponding increase in morbidity and mortality rates (Abdool Karim & Abdool Karim, 2010:363), which impacts greatly on paediatric healthcare services. Adding to this, the provision of paediatric antiretroviral care has numerous stumbling blocks, not least of which is lack of decentralisation of facilities to provide treatment. There is the additional shortage of staff, which includes staff that are comfortable dealing with children, lack of training programmes on the provision of antiretroviral therapy to children, and minimal on-site mentorship of staff regarding HIV/AIDS disease in children. This lack of capacity in the healthcare system means that not all of those who require treatment will be able to access it, and this is particularly pertinent to paediatric patients (Meyers et al., 2007:198). Therefore the purpose of this research was to develop a nursing model that would assist healthcare professionals, in particular professional nurses, to optimise the comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy at PHC clinics. To achieve the purpose of this study, a theory-generating design based on a qualitative, explorative, descriptive and contextual approach was implemented by the researcher to gain an understanding of how the healthcare professionals and parents/caregivers of HIV-positive children experienced the comprehensive treatment, care and support provided at primary healthcare clinics. The information obtained was used to develop a chronic care coordination model for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy. The study design comprised the following four steps: Step One of the research design focused on the identification, classification and definition of the major concepts of the study. This involved describing and selecting the research population and the sampling process prior to conducting the field work which comprised in-depth interviews with two groups of participants, namely healthcare professionals and parents/caregivers who accompany their HIV-positive children to PHC clinics in order to receive antiretroviral therapy. Step Two of the research design focused on the development of relationship statements in order to bring clarity and direction to the understanding of the phenomenon of interest. Step Three of the design concentrated on the development and description of the chronic care coordination model for optimising comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy in order to ensure a well-managed child on ART. A visual representation of the structure of the model for chronic care coordination was given and described as well as a detailed description of the process of the model. Step Four was the last step of the research design and its focus was the development of guidelines for the operationalisation of the model for chronic care coordination for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at PHC clinics. Guidelines and operational implications for each of the five sequential steps of the model were developed. The evaluation criteria of Chinn & Kramer (2008:237‒248) were used to evaluate the model. It is therefore concluded that the researcher succeeded in achieving the purpose for this study because a chronic care coordination model that is understandable, clear, simple, applicable and significant to nursing practice has been developed for use by healthcare professionals, particularly professional nurses, in order to optimise the comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at primary healthcare clinics.

- Description: The human immunodeficiency virus / acquired immune deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. There is a concurrent and distinct increase in the prevalence of HIV/AIDS and HIV-related diseases in the paediatric population in South Africa, particularly those using public sector health services, with a corresponding increase in morbidity and mortality rates (Abdool Karim & Abdool Karim, 2010:363), which impacts greatly on paediatric healthcare services. Adding to this, the provision of paediatric antiretroviral care has numerous stumbling blocks, not least of which is lack of decentralisation of facilities to provide treatment. There is the additional shortage of staff, which includes staff that are comfortable dealing with children, lack of training programmes on the provision of antiretroviral therapy to children, and minimal on-site mentorship of staff regarding HIV/AIDS disease in children. This lack of capacity in the healthcare system means that not all of those who require treatment will be able to access it, and this is particularly pertinent to paediatric patients (Meyers et al., 2007:198). Therefore the purpose of this research was to develop a nursing model that would assist healthcare professionals, in particular professional nurses, to optimise the comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy at PHC clinics. To achieve the purpose of this study, a theory-generating design based on a qualitative, explorative, descriptive and contextual approach was implemented by the researcher to gain an understanding of how the healthcare professionals and parents/caregivers of HIV-positive children experienced the comprehensive treatment, care and support provided at primary healthcare clinics. The information obtained was used to develop a chronic care coordination model for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy. The study design comprised the following four steps: Step One of the research design focused on the identification, classification and definition of the major concepts of the study. This involved describing and selecting the research population and the sampling process prior to conducting the field work which comprised in-depth interviews with two groups of participants, namely healthcare professionals and parents/caregivers who accompany their HIV-positive children to PHC clinics in order to receive antiretroviral therapy. Step Two of the research design focused on the development of relationship statements in order to bring clarity and direction to the understanding of the phenomenon of interest. Step Three of the design concentrated on the development and description of the chronic care coordination model for optimising comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy in order to ensure a well-managed child on ART. A visual representation of the structure of the model for chronic care coordination was given and described as well as a detailed description of the process of the model. Step Four was the last step of the research design and its focus was the development of guidelines for the operationalisation of the model for chronic care coordination for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at PHC clinics. Guidelines and operational implications for each of the five sequential steps of the model were developed. The evaluation criteria of Chinn & Kramer (2008:237‒248) were used to evaluate the model. It is therefore concluded that the researcher succeeded in achieving the purpose for this study because a chronic care coordination model that is understandable, clear, simple, applicable and significant to nursing practice has been developed for use by healthcare professionals, particularly professional nurses, in order to optimise the comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at primary healthcare clinics.

- Description: The possible application of the FT Raman, Raman micro-spectroscopy and ATR-FTIR micro-spectroscopy, have been investigated for distinguishing between wool and mohair. Highly identical Raman and FTIR spectra were obtained from the two fibre types, indicating that indeed they share similar basic molecular structural chemistry. The analysis of the amide I through curve fitting of wool and mohair FT Raman spectra showed that the protein and polypeptide secondary structure exists mainly in the α-helical structural conformation with smaller proportions of β-pleated sheet and β-Turns. These proportions, however, could not be used to distinguish between wool and mohair, due to the significant overlap observed between the two fibres. This study also determined the disulphide contents for possibly distinguishing between wool and mohair fibres, with the average and standard deviation values of 0.20±0.04 and 0.17±0.03 for wool and mohair, respectively, being found. Despite the mean values being found to differ statistically significant (p<0.05), a considerable overlap was observed, posing a doubt in the possible application of the method for distinguishing between the two fibres and blend composition analysis of the two fibres. The application of ratiometric analysis, based on the relative peak heights of certain FT Raman bands, showed that a combination of ratios A (I2932/I1450) and D (I508/I1450) could hold great potential in distinguishing between wool and mohair fibre samples. The individual values of ratios A and D varied a great deal from one mohair sample to the other and even more from one wool sample to another, with the individual values for ratio A ranging from 2.71-3.68 and 2.35-3.08 for wool and mohair, respectively, while ratio D ranged from 0.18-0.32 and 0.17-0.22 for wool and mohair, respectively. An important observation from this study is that if, for an unknown sample, if individual values of ratios A and D exceed 3.1 and 0.22, respectively, are found then the sample is most likely to be either a pure wool or blend of wool and mohair, whereas if all the values fall below the two threshold values, then the unknown sample can be declared a pure mohair sample. A Raman spectral database or library of approximately 100 high quality Raman average spectra of wool and mohair fibres has been established for the Bruker 80V FTIR/Raman spectrophotometer at the Nelson Mandela University (NMU). Although this has not been fully validated due to the unforeseen frequent breakdown encountered with the FT Raman system, at this stage, it has been realized that verification of unknown materials is highly possible. A great need for the development of a classification model based on multivariate or chemometrics has been realized. An ATR-FTIR LUMOS micro-spectroscopic system was also investigated for the possible application in distinguishing between wool and mohair single fibres. The amide I/II band ratios were determined for both wool and mohair fibres to distinguish between the two fibre types. The mean and standard deviation values of 1.20±0.02 and 1.21±0.01 for mohair and wool, respectively, were found and were shown not to differ statistically significant (p˃0.05). The secondary structure analysis showed that the content of the α-helical secondary structure might be different between the two fibre types, with a great overlap of individual values, however, being observed between the two fibre types (wool and mohair), raising concerns in the possible application of the α-helical content for distinguishing the two fibres.

- Description: Construction delays are a global phenomenon. Factors causing construction delays in construction projects differ from country to country, due to different prevailing conditions. The prevailing conditions that could exert an influence on project delivery time are: political, economic, and physical factors as well as level of technological development; management style, and construction techniques. The construction industry is a major player in the economy, generating both employment and wealth. However, many projects experience extensive delays and thereby exceed initial time and cost estimates. This study aims at determining the causes of delays in project delivery in South Africa; evolving interventions, and developing a model for the delivery of projects on time. Inferential and linear regression statistical tools were used in the analysis of data for the study. The sample population consists of architects, builders, quantity surveyors, structural engineers, and clients, and the metropolitan cities of five provinces constituted the geographical delimitation of the study. The provinces are: Eastern Cape; Free State; Gauteng; KwaZulu-Natal, and Western Cape. The metropolitan cities are: Bloemfontein; Cape Town; Durban; Johannesburg, and Port Elizabeth. Findings which negatively influence project delivery time in South Africa include the following: lack of adequate planning; management style; the lack of constructability reviews of designs; inadequate motivation of workers; economic policies; lack of prompt payment to contractors, and quality of management during design and construction. Recommendations include: (1) The introduction of the following courses in built environment tertiary education � quality management competences; operational planning; design management, and generic management; (2) pre-qualification of suppliers; (3) inclusion of the following in tender documentation � human resource schedule; plant and equipment schedule; quality assurance plan, and work schedule; (4) appointment of materials specialists on a large projects; (5) the model developed should be adopted for use in the South African construction industry for the delivery of projects on time, and (6) the linear regression equation: Y = 13.1159 + 1.1341x or 35.3 percent addition on time for the estimation of project delivery time.

- Description: This study investigates the interface between financial and marketing management in South African businesses by investigating the financial and marketing-management processes. This process orientation highlighted important interactions between the two functions. A critical analysis of secondary resources produced a clear theoretical foundation on which the development of the proposed interface framework was based. The critical literature analysis indicates four steps in the financial management process, namely, financial analysis, financial decision-making, financial planning and financial control (independent variables) and five steps in the marketing management process, namely, understanding the marketplace as well as customer needs and wants, designing a customer-driven marketing strategy, constructing an integrated marketing programme, building profitable relationships and capturing value from customers in the form of profits and customer equity. These steps were used to derive a proposed theoretical framework that shows how the steps in the financial-management process relate to those in the marketing-management process. The framework also indicates the perceptions of managers on the interface between the two functions. The perceptions on the interface include aspects such as the level of communication between the two departments, the understanding of each other‟s function and the flow of information between the two departments. From this framework, the six hypotheses were formulated to test the proposed relationships. The focus of the study is on the interface between financial management and marketing management; therefore, the population of this study comprised of financial and marketing managers in South Africa. The primary data relating to the interface between financial management and marketing management was acquired by means of an on-line web-based survey. Descriptive statistics was used to present, analyse and interpret the results of the data analysis. Various inferential statistical techniques (T-tests and chi-squared tests) were employed to determine whether respondents‟ perceptions of the items in the measuring instrument differed as result of whether they were employed in the finance or marketing sections of the business. Correlations (Pearson Product Moment correlations) were calculated for the purpose of investigating the relationships between the financial and marketing management variables used in this study. Factor analysis showed that financial management consisted of four factors that corresponded with the steps in the process, and marketing management produced five factors that related to the steps in the marketing management process. Lastly, statistical tests (MANOVA) were conducted to determine whether the perceptions of respondents, with regard to the financial and marketing management variables, were influenced by selected demographic variables. The results of the empirical study indicated positive relationships between all the variables in the framework. The marketing management factors, namely, mix and profit, reported the lowest correlations compared to the financial management factors. It was also found that financial and marketing managers had different perceptions of the steps in the financial-management process but that they did not have different views of the steps in the marketing-management process. Furthermore, financial and marketing managers had different opinions about the long-term perspective of the business as well as conflicting views with regard to the flow of information from finance to marketing. Financial managers were of the opinion that marketing managers did not understand financial methods and procedures and were unable to specify their requirements to finance. The proposed framework could be seen as the start of marketing theory development on finance interaction as it showed that interface relationships could be further explored.

- Description: Researchers have described human trafficking as a complex, multi-layered crime. South Africa, including the Eastern Cape Province, is a source, transit, and destination country for trafficked people. However, a dearth of research on human trafficking exists in the province. Furthermore, traditional, modernist research using reductionist methods to investigate complex phenomena has proven unable to capture the complex interrelationships between the myriad of interrelated elements inherent in complex phenomena. In this qualitative study, I explore and describe the human trafficking system in the Eastern Cape via participants’ perspectives through a complex systems approach that consists of two complementary theories, namely Bronfenbrenner’s bioecological theory of human development and complexity theory. The participants, who were knowledgeable about human trafficking in the province, were obtained through purposive and snowball sampling. Data collection took place through open-ended interviews with individual participants. I analysed the data according to Miles and Huberman’s data analysis process and Braun and Clarke’s thematic data analysis process. The findings demonstrate that the complex systems approach successfully facilitated the mapping and conceptualisation of an in-depth, multi-level picture of the complex interrelationships within and between multiple system components in the human trafficking system and its environment in relation to the Eastern Cape Province. Participants’ perspectives revealed two main themes, namely, the prominence of the nonlinear interactions between traffickers and trafficked persons in the holistic human trafficking system and the major obstacle regarding the lack of witness credibility for human trafficking prosecutions to be successful. Utilising complex systems theory to conduct further human trafficking research could assist counter-trafficking stakeholders with an alternative approach to generating effective planning and executing counter human trafficking strategies in a rapidly changing and increasing complex interconnected world.

- Description: The process of trade liberalisation and market-oriented economic reforms was initiated in many developing countries in early 1980s; and it intensified in 1990s. In 1991, Zimbabwe was assisted by the IMF to implement trade-policy reforms under Economic Structural Adjustment Programme (ESAP). After adopting ESAP, the country witnessed soaring balance-of-payment problems, contraction of output, unemployment and the loss of government revenue. A number of factors, which were at play resulted in dismal economic performance under ESAP. These factors still exist, in addition to inter alia weak economic policies, structural rigidities and weak institutions. However, notwithstanding this controversy, the country continuously opened its economy under Common Market for Eastern and Southern Africa (COMESA), Southern Africa Development Community (SADC), World Trade Organisation (WTO), Economic Partnership Agreements (EPAs) and bilateral agreements. It is against this background that this study is undertaken, in order to evaluate the impact of different trade-policy regimes on trade, welfare and revenue in Zimbabwe. This study used two models: World Integrated Trade Solutions/Software for Market Analysis and Restrictions on Trade (WITS/SMART) and Tariff Reform Impact Simulation Tool (TRIST). The WITS/SMART model was used because of its ability in analysing the tariff effect of a single market on disaggregated product lines. The model also has the capability to analyse the effects of trade-policy reforms in the presence of imperfect substitutes. In order to complement the WITS/SMART model, a TRIST model was also used. The use of the TRIST model enabled the study to evaluate the impact of trade reforms on VAT, excise duties, collected and statutory revenue – which the WITS/SMART model had overlooked. Using the WITS/SMART model, the study considered seven trade-liberalisation frameworks for Zimbabwe: full implementation of the SADC free trade agreement (FTA), SADC common external tariff (CET), COMESA CET, COMESA FTA, EPAs, BFTAs and WTO FTA.

- Description: This research project was aimed at assessing whether community radio stations are indeed the voice of the community or are set out to fulfil their own agenda. This study therefore looked at three different categories of community radio stations, namely the faith-based radio (Kingfisher FM), geographic community radio (Radio Grahamstown) and institutional community radio (Forte FM) with the aim of studying their activities and comparing the three. Relevant literature has been reviewed and data have been collected using both quantitative and qualitative methods through questionnaires, personal interviews and focus group interviews. The study however leans more on the qualitative approach and a quantitative approach has merely been used to identify the trends of the views of the participants. The analysis of data highlights the views of the respondents about these radio stations as the voice of the community. The views of the respondents from the three radio stations showed that these stations enjoy a very good patronage from the listeners in Port Elizabeth (Kingfisher FM), Grahamstown (Radio Grahamstown) and Alice (Forte FM), respectively. The results and discussions confirm that these radio stations meet their various individual needs of the listeners and that of the community at large. In addition, the fact that participants of the focus groups and survey respondents for these three selected radio stations reported that the Station regularly fulfils the major functions of a radio station, which is to inform, educate and entertain them, showed that these radio stations are acting socially responsible as well. This study was also able to confirm that these community radio stations do give opportunities to listeners to contribute to programme content development, which shows the willingness of these stations to give voice to the listeners and allow them to be part of their own personal development and that of the community at large.

- Description: This research project was aimed at assessing whether community radio stations are indeed the voice of the community or are set out to fulfil their own agenda. This study therefore looked at three different categories of community radio stations, namely the faith-based radio (Kingfisher FM), geographic community radio (Radio Grahamstown) and institutional community radio (Forte FM) with the aim of studying their activities and comparing the three. Relevant literature has been reviewed and data have been collected using both quantitative and qualitative methods through questionnaires, personal interviews and focus group interviews. The study however leans more on the qualitative approach and a quantitative approach has merely been used to identify the trends of the views of the participants. The analysis of data highlights the views of the respondents about these radio stations as the voice of the community. The views of the respondents from the three radio stations showed that these stations enjoy a very good patronage from the listeners in Port Elizabeth (Kingfisher FM), Grahamstown (Radio Grahamstown) and Alice (Forte FM), respectively. The results and discussions confirm that these radio stations meet their various individual needs of the listeners and that of the community at large. In addition, the fact that participants of the focus groups and survey respondents for these three selected radio stations reported that the Station regularly fulfils the major functions of a radio station, which is to inform, educate and entertain them, showed that these radio stations are acting socially responsible as well. This study was also able to confirm that these community radio stations do give opportunities to listeners to contribute to programme content development, which shows the willingness of these stations to give voice to the listeners and allow them to be part of their own personal development and that of the community at large.

An investigation into the role of Xhosa male initiation in moral regeneration

- Description: This research study in Mdantsane (East London), Whittlesea (Hewu), Njiveni (Libode) and Cala sought to investigate the role of the amaXhosa male initiation in moral regeneration focusing on socio-cultural, educational and religious aspects related to moral values. The role of the amaXhosa male initiation as a rite of passage from boyhood to manhood, how it was viewed in the past, its impact upon the initiates and its contribution to the moral upholding of values were investigated. It was further intended to establish whether westernisation and urbanisation brought a shift of meaning and emphasis to the current initiation practice and, if so, to what extent has the ceremony departed from traditional norms and what challenges the ceremony has to face at present. A qualitative research method involving an ethnographic study was utilised, which includes in-depth, semi-structured interviews (formal interviews and informal discussions) and participant observation. Research findings suggested that in the past the amaXhosa male initiation played a role in the instruction of moral values. However, this study identified a shift of meaning in the practice which has been more evident in urban than in rural areas. The shift suggested that the instruction role has changed in prominence and there is less emphasis on teaching and appropriate adult behaviour. Moreover that the amakhankatha, who had the major role in teaching of the initiates are now participating in making the role less effective and sometimes introducing influences that are destructive to the initiates. Such negative influences include abuse of alcohol and drugs, promiscuity among the youth and disobedience of elders. It is argued that revisiting the teachings surrounding male initiation may cultivate productive debates on how young males are taught morality in today's society. Furthermore, that if the Xhosa male initiation could be contextualised it can play a role in the instruction of boys as they graduate to manhood and that can contribute to moral regeneration in South Africa.

- Description: The governance of data assets has become a topical issue in the public sector. Government departments are faced with increasingly complex data and information arising from multiple projects, different departments, divisions and several stakeholders seeking data for divergent end uses. However, an exploratory study of the literature regarding data governance in government departments of the Eastern Cape province of South Africa suggest that there are no clear data governance processes in place within the departments. The research question “How can a data governance maturity evaluation model enhance data governance processes in the Eastern Cape government departments” was derived as a result of a perceived need for government departments of the province to manage their critical data assets in a manner which promotes accurate, verifiable and relevant fiscal and strategic planning. Following the review of current literature in the data governance domain, a conceptual data governance evaluation maturity model was developed and produced. The conceptual model was influenced by the IBM data governance maturity model (2007) and it was aimed at addressing the gaps in the reference model to suit the context of the Eastern Cape government departments and the governance of their data assets. A qualitative phase of empirical data collection was conducted to test the components of the conceptual model. A quantitative instrument, derived from the findings of the qualitative study, as well as the components of the refined model was administered to 50 participants in the same departments where qualitative data was collected, with additional participants being drawn from three other departments. Pragmatism was the guiding philosophy for the research. The Contingency and Institutional theories form the theoretical grounding for the study. Design Science guidelines by Hevner et al (2004), Peffers et al’s (2008) Six Steps in Design Science and Drechsler & Hevner’s (2016) Fourth Cycle of Design Science were employed to construct, improve, validate and evaluate the final artefact. Findings confirmed the literature that data governance is lacking in government departments. It is asserted that the implementation of this model will improve the way data assets are recorded, used, archived and disposed in government departments of the Eastern Cape. The outcome of this research was the development and production of a data governance maturity evaluation model as well as a process document which gives a roadmap of how to move from one maturity level to another.

An analysis of the role of Non-Govermental Organisations in the social welfare policy process: a case study of Zimbabwe

- Description: This study is an interpretive analysis of the roles of NGOs in the social policy process, using the case of postcolonial Zimbabwe. Assessing the period between 2000 and 2010 and the prevailing unique socio-economic and geopolitical crisis, the study engages the major contextual factors influencing evolution of NGOs and their engagement in the policy process. It focuses on the conceptual and state – civil society contestations on the legitimacy of NGO’s as well as an assessment of their impact on the social policy process. NGOs in Zimbabwe have played two major and two minor roles in the social policy process as identified in the study in terms of their prominence and impact on the policy process. That is: policy implementer role complementing state social policy provision, democratisation to pluralism the social policy arena as the major roles; educational role to developing interventions for better social policy and watchdog role monitoring government and other state institutions in meeting the social policy needs of citizens. The thesis argues that analysis of NGOs is embedded in understanding the role of the state and dialectical relationship between state and civil society. Using a neo-Marxist perspective and social democratic approach to the role of the state in social policy, the theoretical generalisations of the study are that NGOs have a legitimate role to play in the social policy process. However, this is defined by the nature and role of the state itself as central driving agent in social policy. Therefore, the roles NGOs are not exclusive in themselves but are anchored within the contextual framework and its definition of societal spheres within it. The thesis established the evolution of the NGO sector in Zimbabwe, its impact on the social, political landscape and argues that the democratisation agenda in Zimbabwe requires a political solution embedded in a transformative state as the panacea for building a redistributive and participatory social policy agenda that engages with non-state actors, NGOs included within a developmental framework. Conclusively, the thesis proposes a theoretical distinction between NGOs as service oriented entities and CSOs as forums for associational life and civic engagement.
