- Description: The fight against poverty is one of South African government priorities and challenges. Despite the large amounts of funds donated by government to poverty alleviation in South Africa almost half of the population still continue to live below the poverty line. There have been many government interventions towards projects. These projects are established in an effort to reduce poverty. However, most of these projects have had a minimal impact on the poverty level of the country. In this study, the researcher illustrated the impact of community development projects on poverty alleviation in Lubala village in Ingquza Hill Local municipality. The research methodology for the study is descriptive, sourced from available literature.

- Description: Nowadays young people and other members of the society often find themselves in many malpractices such as rape, suicide, murder dropping out of school and other harmful activities due to the use of cannabis sativa (dagga) which is on the rise. This study concentrated on the use of cannabis sativa (dagga) in Mzintlava, Ngquza Hill Local Municipality in the Eastern Cape Province of South Africa. Young people are actually the victims of the consequences of the use of dagga. Indications are that parents often ignore their children to use cannabis sativa until they can no longer stop them. Earlier researches on substance use in South Africa have always been descriptive. This resulted in sketchy understanding of factors that predisposed young children to the use and even abuse of dagga and the reasons why parents and the community underestimated the practice until the stage of addiction. Without this understanding, it will be difficult to introduce effective ways of abolishing dagga use among young children and other members of the community. Finding effective measures to prevent substance use has been difficult. Research is therefore needed in order to understand the basis of the problem. This study attempts to examine factors that make parents and the communities to leave children to taking substances until the stage where they can longer stop them. It will also lead to establishing factors that put young children or teenagers particularly at risk to the use of dagga.

- Description: The fluorescence and photoactivity of a series of Zn and Lu phthalocyanine complexes incorporated in various polymer fibers were investigated for the phototransformation of 4-chlorophenol, 4-nitrophenol, and methyl orange. The phthalocyanine complexes functionalized on polystyrene and polysulfone polymer fibers could be applied in the degradation of 4-chlorophenol, 4-nitrophenol, and methyl orange with 4-chlorophenol being much more susceptible to degradation while methyl orange was the least. Also polymer fibers of polystyrene were found to be reusable.

- Description: Investigations into the thermal physiology of weed biological control agents may elucidate reasons for establishment failure following release. Such studies have shown that the success of water hyacinth biological control in South Africa remains variable in the high-lying interior Highveld region, because the control agents are restricted to establishment and development due to extreme winter conditions. To determine the importance of thermal physiology studies, both pre- and post-release, this study compared the known thermal requirements of Eccritotarsus catarinensis (Carvalho) (Hemiptera: Miridae) released in 1996, with those of an agent released in 1990, Niphograpta albiguttalis (Warren) (Lepidoptera: Pyralidae) and a candidate agent, Megamelus scutellaris Berg (Hemiptera: Delphacidae), which is currently under consideration for release. The lower developmental threshold (to) and rate of development (K) were determined for N. albiguttalis and M. scutellaris, using a reduced axis regression, and incorporated into a degree-day model which compared the number of generations that E. catarinensis, N. albiguttalis, and M. scutellaris are capable of producing annually at any given site in South Africa. The degree-day models predicted that N. albiguttalis (K = 439.43, to = 9.866) can complete 4–11 generations per year, whereas M. scutellaris (K = 502.96, to = 11.458) can only complete 0–10 generations per year, compared with E. catarinensis (K = 342, to = 10.3) which is predicted to complete 3–14 generations per year. This suggests that the candidate agent, M. scutellaris, will not fare better in establishment than the other two agents that have been released in the Highveld, and that it may not be worth releasing an agent with higher thermal requirements than the agents that already occur in these high-lying areas. Thermal physiology studies conducted prior to release are important tools in biological control programmes, particularly those in resource-limited countries, to prevent wasting efforts in getting an agent established.

- Description: Poverty is a major challenge in most developing countries. Key challenges of the government are to alleviate poverty and propel citizens toward wealth creation through development of enterprises across all sectors and to address the problem of unemployment. In Kenya, the SME sector comprises of about 99% of private sector enterprises and is prolific in employment and wealth creation. Despite this critical role played by SMEs in growing the economy, they remain outside the formal banking sector, especially in Africa. Although the number of MFOs since the 1980s has increased, the demand for financial services is largely unmet. However, MFOs are increasingly experiencing competition from new entrants and commercial banks that have developed financial models to target SMEs. MFOs are required to formulate and implement competitive strategies to enable them achieve sustainable growth and compete with commercial banks. However, strategy implementation is generally accepted as a challenge across organisations and it is often easier to formulate strategies than implementing it. Despite the need to address strategy implementation challenges across organisations, there is a greater focus by practitioners and researchers regarding strategy formulation than implementation. Consequently, this study aimed at assessing the level of strategy implementation in MFOs and factors that affect strategy implementation in MFOs. The ultimate objective was to develop a hypothetical model that could be used to improve strategy implementation in microfinance organisations in Kenya. This quantitative study used purposive sampling to select MFOs that are members of the Association of Microfinance Institutions (AMFI) in Kenya, completing a selfadministered structured questionnaire. In total, 135 MFOs were involved in this study and a total sample size of 300 managers was used in this study. This study considered fourteen factors to have an influence on the level of strategy implementation of MFOs in Kenya and hence fourteen null-hypotheses were formulated and tested. The content factors included stakeholder involvement in strategy development and the quality of strategies. The context factors included organisational structure and culture, strategic leadership and alignment of strategy to market conditions. The operational process factors included operational planning, monitoring and review of progress, teamwork, resources allocation, people-strategy fit, effective communication, strategic and management control systems and information resources. It is assumed that if all these critical strategy implementation factors are addressed, MFOs should be able improve their level of strategy implementation, ultimately leading to improved performance. The outcome factors considered were improved financial sustainability and outreach of MFOs. Advanced statistical analyses were used to analyse the data, such as factor analysis, regression and correlation analysis to assess the hypothesised relationship between the dependent and independent variables of this study. The empirical results revealed that the level of strategy implementation in MFOs in Kenya is moderate to high and content, context and operational factors do have an influence on the level of strategy implementation. However, operational factors have a more significant positive linear relationship with level of strategy implementation than the other two factors. There is also a positive relationship between the level of strategy implementation and financial sustainability and outreach by MFOs. This study has contributed to the existing body of knowledge by developing a hypothetical model that can be utilised by MFOs as well as other organisations to improve the level of strategy implementation resulting in better performance. The findings of the study can also inform strategy formulation and implementation of MFOs in Kenya, but also in other developing countries, to become more competitive. This study could also help MFOs and other organisations to put in place structures, systems, people and other resources required to attain a high level of strategy implementation. This study provides useful and practical guidelines in dealing with content, context and operational factors affecting strategy implementation in any organisational setting.

- Description: This study describes the preparation, characterization and evaluation of new composite membranes with embedded dendrimer hosts and Fe/Ni nanoparticles. These new reactive membranes consist of films of cyclodextrin–poly(propyleneimine) dendrimers (β-CD–PPI) that are deposited onto commercial polysulfone microporous supports and crosslinked with trimesoyl chloride (TMC). The membranes were subsequently loaded with Fe/Ni nanoparticles and evaluated as separation/reactive media in aqueous solutions using 2,4,6-trichlorophenol as model pollutant. The morphology and physicochemical properties of the composite membranes were characterised using high-resolution transmission electron microscopy (HR-TEM), atomic force microscopy and measurements of contact angle, water intake, porosity and water permeability. The sorption capacity and catalytic activity of the membranes were evaluated using ion chromatography, atmospheric pressure chemical ionisation-mass spectrometry and UV–Vis spectroscopy (UV–Vis). The sizes of the embedded Fe/Ni nanoparticles in the membranes ranged from 40 to 66 nm as confirmed by HR-TEM. The reaction rates for the dechlorination of 2,4,6-trichlorophenol ranged from 0.00148 to 0.00250 min−1. In all cases, we found that the reaction by-products consisted of chloride ions and mixtures of compounds including phenol (m/z = 93), 2,4-dichlorophenol (m/z = 163) and 4-chlorophenol (m/z = 128). The overall results of this study suggest that β-CD–PPI dendrimers are promising building blocks for the synthesis of composite and reactive membranes for the efficient removal of chlorinated organic pollutants from water.

- Description: World records in athletics capture the attention of both the general public and the academic community. Athletics records provide a wealth of quantifiable data, which represent the pinnacle of human ability at the time of the record. This research discusses modelling the progression of athletics world records using a compound distribution model which is found in actuarial statistics. Compound distributions allow for the simultaneous modelling of the frequency of record breaking and of the amount by which the record is improved at each record-breaking performance. A number of assumptions accompany the use of the compound distribution model. This research evaluates the athletics data for adherence to these assumptions, before carrying out distribution-fitting and goodnessof-fit testing. Forecasts of future performance are obtained by means of a simulation method. The forecasts obtained from the compound model are compared to forecasts obtained from non-linear models which have been proposed in literature. This research focuses on short-term forecasts, however, a modification to the compound model which allows for longer-term forecasts is also illustrated.

- Description: This article reports on regularities observed in learners’ preconceptions of reflective symmetry. Literature suggests that the very existence of such regularities indicates a gap between what learners know and what they need to know. Such a gap inhibits further understanding and application, and hence needed to be investigated. A total of 235 Grade 11 learners, from 13 high schools that participate in the First Rand Foundation-funded Mathematics Education project in the Eastern Cape, responded to a task on reflective symmetry. Our framework for analysing the responses was based on the taxonomy of structure of the observed learning outcome. The results indicated that 85% of learner responses reflect a motion understanding of reflections, where learners considered geometric figures as physical motions on top of the plane. While this understanding is useful in some cases, it is not an essential aspect of mapping understanding, which is critical for application in function notations and other analytical geometry contexts. We suggest that if this gap is to be closed, learners need to construct these reflections physically so that they may think of reflections beyond motion.

- Description: In today’s world, we have reached the point where conventional energy forms are inevitably running out. At the same time, the technology for alternative energy harnessing is improving with big steps, especially with society rethinking their high consumption of finite energy and material. This opens the opportunity und increases acceptance for projects and research to prove its actual implementation and to push the boundaries of current technology further.One particular area of application is the automotive sector showcasing raise of costs due to depleting fuel. Solar powered cars are raising interest as it could be a way to complete independence of any resource that has to be produced, mined or in any way transported to the place of consumption. Involvement with the view to enhance their research in this field has become interesting for universities.With solar powered cars, new problems emerge, amongst others the amount of harnessed sun power and the storage to have it available at the point of use. Due to the low energy available, energy storage as light and as efficient as possible is needed.

- Description: In today’s world, we have reached the point where conventional energy forms are inevitably running out. At the same time, the technology for alternative energy harnessing is improving with big steps, especially with society rethinking their high consumption of finite energy and material. This opens the opportunity und increases acceptance for projects and research to prove its actual implementation and to push the boundaries of current technology further.One particular area of application is the automotive sector showcasing raise of costs due to depleting fuel. Solar powered cars are raising interest as it could be a way to complete independence of any resource that has to be produced, mined or in any way transported to the place of consumption. Involvement with the view to enhance their research in this field has become interesting for universities.With solar powered cars, new problems emerge, amongst others the amount of harnessed sun power and the storage to have it available at the point of use. Due to the low energy available, energy storage as light and as efficient as possible is needed. A system is required that allows to be operated independently of its surrounding in a way it is controllable.Lithium-ion based batteries were seen as the most applicable way to execute this, as they give the highest energy density with lower losses than stable, commercially available energy storage mediums.It was decided to design, build and integrate a battery system with its safety circuit into a solar car.

- Description: This study investigates the constructions of nationhood in two Bulawayo newspapers, the Chronicle and Newsday. Against the backdrop of the emergence of a secessionist movement, Mthwakazi Liberation Front (MLF), this research examines the discourses of nationhood in the secessionist debates raging in these two newspapers. This study is premised on a view that nationhood constructions cannot be understood outside the broader context in which these newspapers are embedded. Accordingly, it traces the roots and resurgence of Matabeleland separatist politics, exploring the political-historical forces that have shaped a distinctive Ndebele identity that poses a threat to the one, indivisible Zimbabwean national identity. Further, the study situates Matabeleland separatist politics within the broader African secessionist discourse challenging the post-colonial nation-building project on the continent. Informed by Hall’s (1992, 1996) constructivist approach to identity, it considers national identities as fragmented, multiple and constantly evolving. Thus, this study is framed within Hall’s (1997) constructivist approach to representation, as it examines the constructions of nationhood in and through language. The study uses qualitative research methods, as it examines the meanings of nationhood in key media texts. Informed by Foucault’s discourse theory, this research employs critical discourse analysis (CDA) to analyse 12 articles from the two newspapers. The findings confirm that the representations of nationhood in the two newspapers are influenced by their position within the socio-political context. The state-owned Chronicle legitimates the unitary state discourse advocated by ZANU PF. On the other hand, Newsday’s representations are informed by the discourses of the opposition political parties and civil society that challenge the dominant nation-building project. Thus, within this paper, secession and devolution emerge as alternative imaginaries that contest the authoritarian discourse of nationhood

- Description: Content and Language Integrated Learning (CLIL) is an innovative educational approach in which an additional language is used for the learning and teaching of both language and subject content. Content and Language Integrated Learning is not commonly used in South African classrooms, but its application internationally has been shown by empirical research to significantly improve overall language competence in the target language. Reports indicate increased learner motivation and support for the learning of the content subject. This study sought to consider whether CLIL intervention would improve both language and science skills amongst Grade 8 learners in a Natural Sciences classroom. The researcher used a concurrent embedded mixed method design, including both quantitative and qualitative methodologies to gather data. An experimental test design with English Home Language classes and Afrikaans Home Language classes was employed. Hypothesis Testing was used as a statistical analysis to compare the pre-test and post-test results in order to ascertain the impact of CLIL intervention. In addition, the poster-activity and an open-ended questionnaire was used to qualitatively ascertain the impact of CLIL on learner literacy skills. The results showed that CLIL intervention improved learner performance significantly when compared to learners who were not exposed to CLIL. In addition, CLIL lessons were perceived as effective and learners verified that the approach was beneficial to their learning process.

- Description: Sodwana Bay, situated within the iSimangaliso Wetland Park, is ecologically important as it contains high-latitude corals and the most southerly known population of coelacanths. This thesis utilised stable isotope and lipid analyses to investigate the trophic ecology of the area, in particular, understanding the relative contribution of inshore and offshore primary production to consumers inhabiting intertidal and shallow subtidal, coral reef, deep reef, canyon head and pelagic habitats. Seaweeds, excluding certain species of red seaweeds with highly depleted carbon signatures, and phytoplankton, such as diatoms, were found to be the principal sources of primary production for all consumers. Offshore production was typified by dinoflagellates. Particulate organic matter (POM) was spatio-temporally variable. Three distinct productivity periods related to nutrient cycling were noted with enriched carbon signatures and higher organic matter loads associated with warmer water. Inshore primary production was an important source of carbon to consumers in all habitats with the exception of zooplankton that were more reliant on pelagic primary production. Benthic invertebrates reflected a gradient in the utilisation of inshore production, due to the reduced availability of this source further offshore. Consumers at the furthest sites offshore were found to include a substantial quantity of inshore-derived production in their diets. Fishes, which are more mobile, were found to incorporate a similar proportion of inshore production into their diets regardless of where they were collected from.

- Description: Audio/Video Bridging (AVB) on Ethernet refers to a suite of standards that allows for deterministic and guaranteed delivery of audio and video content on Virtual Local Area Networks (VLAN). A requirement for the networking of audio devices is to allow for remote establishment and destruction of audio stream connections. There are a number of sound control protocols that utilize AVB transport, and this paper describes an approach for common control and interoperability among them. To demonstrate this approach, this paper describes the design and implementation of a command translator that enables communication between AES64 and OSC-networked AVB devices. Results from a quantitative analysis reveal that when a proxy is used for connection management, noticeable delays are not added to a user’s visual and auditory perception.

- Description: The present study investigated controls on the formation of Wakkerstroom Vlei, an 1 000 ha unchannelled valley-bottom wetland on the South African Highveld. Along the uppermost and lowermost reaches of the wetland, where dolerite outcrops occur along the main valley, hydrogeomorphic features typical of geological control on wetland formation are present, including a meandering river channel, oxbow lakes and greater than 3 m deep organic-poor alluvial fill. Along the main body of the wetland, however, floodplain features are absent, alluvial fill is up to 4.5 m deep and contains up to 2 m deep accumulations of peat. These characteristics deviate from the traditional model of dolerite control on wetland formation described by several other studies on Highveld wetland systems.

- Description: This thesis seeks to understand and analyse HIV and AIDS and rural livelihoods in Zimbabwe with particular reference to an isolated and marginalised informal settlement called Chivanhu in Masvingo Province. The focus is specifically on questions around HIV susceptibility, AIDS vulnerability and household resilience. In this regard, it is important to recognise that HIV and AIDS cannot be lumped together as one medical or social condition. Rather, there is a progression from HIV infection to AIDS-related chronic illnesses to possible death, and livelihood strategies often alter along this HIV and AIDS time-line. Zimbabwe for over a decade now has gone through a series of economic and political crises which have impacted detrimentally on both urban and rural livelihoods, even for those households which are not directly affected by the HIV and AIDS pandemic. With the economy in free-fall, households have had to pursue a range of livelihood strategies in order to sustain themselves. These socio-economic conditions have in many ways facilitated susceptibility to HIV infection and vulnerability to AIDS. Many studies have examined this in relation to wellentrenched and stable communities in rural Zimbabwe. But the livelihood dynamics for such communities are significantly different to more unstable and informal settlements like Chivanhu, as thesis seeks to show. At the same time, the thesis offers a longitudinal study which is able to map the changes to the livelihoods of infected and affected households in Chivanhu. Though recognising the debilitating effects of the pandemic on these households, it also raises questions about the possible resilience of certain households despite great adversity. In doing so, it goes beyond the individual and household levels of analysis to consider the role of clusters (or groups of households) in responding to the impacts of HIV and AIDS. In this regard, particular emphasis is placed on gender and orphanhood. In the end, the thesis offers a nuanced analysis of the everyday complexities and challenges for affected households in a marginalised and informal rural community in Zimbabwe and thereby makes a contribution to re-theorising HIV and AIDS and rural livelihoods more broadly.

- Description: The primary aim of this research study was to determine the current state of practice of corporate social responsibility (CSR) within the ecotourism based private game reserve (PGR) industry in the Eastern Cape Province of South Africa. According to Carroll (1991) four kind of responsibilities constitute total CSR, namely economic, legal, ethical and philanthropic responsibilities. Given the context of this research a fifth responsibility concerning environmental responsibilities was added to Carroll 's (1991) pyramid ofCSR. A descriptive and illustrative case study approach, within the phenomenological research paradigm, was used for the purpose of this research. The unit of analysis is the Indalo group, the Association of Eastern Cape Private Game Reserves, made up of 12 ecotourism based PORs. As the current research focused on eight of the twelve PGRs a mUltiple case study was employed. To give effect to the aim a number of research objectives were identified. Firstly to desclibe and assess the current practice in implementing CSR within the ecotourism based PGR industry in the Eastern Cape Province. Secondly, to assess and evaluate the involvement of ecotourism based PGRs in the Eastern Cape Province in each of the five responsibilities comprising CSR. Thirdly, to identify the challenges faced by ecotourism based PGRs in the Eastern Cape Province with regard to the implementation of CSR initiatives. Lastly to provide pertinent conclusions and recommendations with regard to CSR strategies within the ecotourism based PGR industry in the Eastern Cape Province. Data were collected by means of in-depth interviews with the managers of each reserve. In addition the researcher conducted focus interviews with administrative employees at each of the member reserves of the Indalo group. Additionally the managers of each reserve were requested to respond to a structured five point Likert scale questionnaire based on the research by Aupperle, Carroll and Hatfield (1985). This research study found that the current practice at the Indalo group is towards a strategic, long term approach to CSR that aids in the development of a 'sustainable organisation.' The aspect of ' empowerment' emerged as the essence of the current practice ofCSR of the Indalo group. Based on the current practice it was concluded that the Indalo group is actively involved in the specific components of CSR namely, environmental, economic, legal, ethical and philanthropic responsibilities. With regard to the environmental responsibilities it was concluded that the environment is the foundation upon which all other components of CSR rest. In addition it was concluded that the economic responsibilities, if managed well, are key to unlocking the CSR potential of a reserve as well as ensuring widespread economic development. In terms of the legal and ethical responsibilities it was concluded that tourism policies both at the national and international level have not aided in the development of a CSR agenda of the Indalo group. Furthermore managers of the reserves have been instrumental in cultivating their own legal culture of CSR based on their experience in the tourism industry and their ethical stances. In terms of the philanthropic responsibilities it can be concluded that charitable activities that are long term and strategic in nature allow for direct and indirect benefits to all parties involved. Overall, it can further be concluded that despite Hudson and Miller's (2005:5) view that the "tourism industry is well hehind other industries in terms of CSR" the Indalo group is moving forward in terms of rooting CSR into their everyday operations.

- Description: Publisher version , One of the proposals for fighting rhinoceros poaching is to legalise the trade in rhino horn and adopt a regulated market approach (RMA), which would require a vote at the 2016 CITES meeting in order to overturn the ban on the trade in rhino horn. The legal trade in rhino horn would enable the auctioning of stockpiles of horn and encourage captive breeding programmes. The aim of increasing the supply of horn is to reduce incentives to poach by driving down the price. This paper uses a conceptual/theoretical approach to consider the practical implications of the adoption of an RMA, drawing on demand, supply and production theory. The intention is explicitly to set out some practical concerns and issues that seem to have been underplayed or neglected in most published economic discourse on the subject. To secure a stockpile for some species needs biological success in captive breeding programs (CBPs) but this varies across species and habitats. Rhinoceros herds in a CBP would need relatively spatially extensive terrain and costly permanent security measures, and only appear feasible for the less aggressive “white” rhino. Thus, market price would actually need to be sustained at a high level to cover the start-up and security costs of such a programme that are unlikely to fall significantly. This is a double-edged sword in that the persistent high price of rhino horn provides an incentive for continued poaching activities. Supplementary policy measures that differentiate among consumer groups may also prove necessary.

- Description: Publisher version , One of the proposals for fighting rhinoceros poaching is to legalise the trade in rhino horn and adopt a regulated market approach (RMA), which would require a vote at the 2016 CITES meeting in order to overturn the ban on the trade in rhino horn. The legal trade in rhino horn would enable the auctioning of stockpiles of horn and encourage captive breeding programmes. The aim of increasing the supply of horn is to reduce incentives to poach by driving down the price. This paper uses a conceptual/theoretical approach to consider the practical implications of the adoption of an RMA, drawing on demand, supply and production theory.

- Description: This thesis aims to critique the Universal Declaration of the Rights of Mother Earth and its underlying moral justification in order to provide a stronger and improved version of both. In Chapter 1 I explore what sort of moral justification is necessary to establish the Universal Declaration on firm grounds and explore its relation to environmental ethics and rights discourse. I argue that a non-anthropocentric perspective is necessary to justify the Universal Declaration’s rights. In Chapter 2 I explore the underlying justification of the Universal Declaration as discovered in the works of Cormac Cullinan and Father Thomas Berry. I argue that their ethical framework is indeterminate, has many ambiguities and uncertainties, and, among other problems, it does not provide a clear action-guiding framework. In Chapter 3 I develop an alternative justification for the Universal Declaration. I argue against many predominant moral theories, that in light of our best scientific and moral understanding we should expand the realm of moral concern to include all living beings, a moral theory I call Life’s Imperative. In Chapter 4 I illustrate that Life’s Imperative is a much stronger, more coherent justification for the Universal Declaration, one that coheres with both our best understanding of the natural world and our relation to it, and to an environmental ethic reflective of that relationship. Unfortunately many of the weaknesses in the current implicit justification of the Universal Declaration have also led to it enshrining rights that are themselves problematic. In order to address these issues, I revise its rights to accord with the stronger justification that I established in Chapter 3. The end result of doing so is a revised version of the Universal Declaration
