- Description: This half-thesis examines how editorial values and perceptions determine the quantity and nature of science articles published in the Daily Dispatch, a newspaper distributed through large parts of the Eastern Cape in South Africa. It was predicated on the notion that South African media in general does not cover the natural sciences adequately. In order to test this assumption I decided to investigate the production and publication of science content at the Daily Dispatch as a test case. This study‘s theoretical framework draws on the normative roles of the media in a democracy developed by Christians et al. (2009) and the models of science journalism described by Secko et al. (2012) to demonstrate how two parallel conceptions of democracy set diverse journalistic objectives and engender different types of science content. Having applied an essentially political framework, this thesis uses the Hierarchy of Influences Model devised by Reese and Shoemaker‘s (2014) to explore how an array of forces acting inside and outside the news organisation can shape the publication of science articles. A quantitative content analysis is used to ascertain the number of science articles published in the first six months of 2014. It investigates which science fields received the most coverage, and how prominently the articles are positioned. As the Daily Dispatch does not have any staff dedicated to the science beat, the analysis finds out who produces the science articles that are published. The second phase of this research is a series of interviews with senior editorial staff members aimed at probing the editorial thought processes that determine when and whether specific science stories should be covered. The personal views and biases of the editorial leadership are pivotal to this research because although the newspaper commissioned surveys to determine readership preferences, there were no questions about the sciences. Senior reporters were adamant that they worked for a political newspaper and that as a significant proportion of their readership lived in socio-economically deprived circumstances, they were bound to give priority to articles aimed at improving the lot of their readers. The third phase is a qualitative content analysis of selected articles designed to reveal how science articles are constructed. The final element of this thesis, which ultimately provides an answer to the research question, draws together conclusions from the previous phases to demonstrate the linkage between editorial values and the production of science content.

- Description: Biodiversity stewardship is a mechanism that is used to conserve high value biodiversity assets. Biodiversity stewardship programmes focus on areas that are under immediate threat from development or under medium to long term threat from degradation or transformation that will result in habitat loss. Biodiversity stewardship provides a solution to the resource crisis being faced by many state and provincial conservation agencies, NGO’s (Non-Governmental Organisations) and PBO’s (Public Benefit Organisations) in that it facilitates the declaration, and the subsequent improved conservation management, of private or communally owned land whilst still retaining the existing tenure. The rate of habitat loss can often be slowed, or even reversed, by proactively securing these areas and facilitating management decision-making with a focus on biodiversity outcomes without the capital investment required by the State to purchase the land. In return for conservation management actions, certain land-use restrictions and the associated opportunity costs, the State offers a suite of incentives and benefits that are, where possible, tailored to meet the needs of the landowner. Particular regions of South Africa lend themselves well to the development of biodiversity stewardship initiatives which are designed to secure ecological processes and ecosystems across a landscape or an ecological feature at scales of tens of thousands of hectares. When developing landscape level biodiversity stewardship initiatives, negotiations tend to be focussed on groups of landowners. This requires collaboration and the collective alignment of natural resource management decision-making and conservation actions amongst neighbours. Gaining a better understanding of how the social constructs of ecological understanding, place attachment, connectedness to nature, occupational identity and social and personal identity influence decision-making, behaviour and group structure is a critically important factor when developing a tool to predict the likelihood of landowners to collectively commit to long-term, legally binding biodiversity stewardship programmes. The overarching hypothesis was that the social constructs listed above influence group dynamics within the context of collective pro-conservation behaviour. Social dynamics associated with large-scale biodiversity stewardship initiatives become complex when multiple landowners are involved. Could social cohesion and group culture be influenced by aspects of identity and do these in turn develop into barriers or motivators to coordinated and sustained conservation efforts? Further influences on the successful implementation of landscape scale biodiversity stewardship initiatives could include ecological understanding, connectedness to nature and place attachment. Structured interviews were held with the landowners engaged in two separate large-scale biodiversity stewardship sites, the Compassberg Protected Environment and the Baviaanskloof Hartland, in the Eastern Cape Province of South Africa. The interviews were followed up with surveys containing psychometric scales related to the influence of ecological understanding, place attachment, connectedness to nature and aspects of identity on commitment to collective long-term, large-scale biodiversity stewardship initiatives. The results from a set of non-parametric (exact) Wilcoxon rank-sum tests showed that scores on the new ecological paradigm scale and the place attachment scale latent variables were significantly different at the two study sites, at the 10% level of significance. Demographic differences between the two study sites influenced group dynamics, collective decision-making and commitment. The relationship between the latent variables (the five psychometric scales measured) and the ancillary variables (the demographic data describing the respondents) cannot be considered conclusive; however they do provide relatively useful insights into the development of a scale or tool to measure conservation opportunity. The thesis concludes with a proposed conservation opportunity assessment tool that can be utilised alongside the existing, well refined, conservation priority assessment tools to assist in decision-making when planning large, landscape scale biodiversity stewardship initiatives in South Africa.

They reconnect with nature, the now ravaged landscapes that gave me my first impulse to make songs, poetry, and art. My poems also draw on my Xitsonga culture – its folklore, proverbs, idioms, parables, and clan praise songs. Stylistically I am influenced by Mahmoud Darwish’s and Garcia Lorca’s musical structures, while Aimé Césaire has shown me how to write a long poem in both abstract and concrete registers, and Yehuda Amichai how to write with a questioning style, dislodging accepted dogma. Local influences are Mzi Mahola and James Magaisa, with their critique and celebration of culture. I pick up fragments elsewhere, as I go.

Ideas of poetic form: aspects of the Romantic-Symbolist tradition

- Description: The subject of the work is some of the formal and technical developments of modern poetry in the Romantic-Symbolist tradition. These developments were stimulated partly by the ideas of the non-intellectual Symbol inherited from the Romantics and the idea that poetry could be a musical medium inherited from some of the French Symbolists. Their combined influence led to a number of technical problems in the structuring of imagery and the handling of syntax. The work begins, therefore, by tracing the philosophical assumptions behind the ideas of the Symbol and of the musical analogy. I then go on to examine two of the difficulties that these ideas produced. One is the tension between the analogical structure of a poem’s imagery and its metaphorical texture: quite simply, the more compressed and complex a poet’s metaphors become, the more they tend to disrupt the poem’s structure of imagery. The other problem is obscurity, which is caused by insufficient objectification of private images in a symbolic structure, and by fused metaphor, which is essentially a metaphor with an obscured ground of resemblance. Finally, I show how these difficulties were solved by poets outside the tradition who used a more articulate kind of syntax, yet who also managed to combine that syntax with the ideal of symbolic form. The implicit argument, then, is that the Romantic-Symbolist ideas of form, and the New Critics’ theories of form which were largely based on them, are able to elucidate an essentially different kind of poetry, and thus have some degree of truth and use beyond the tradition that generated them.

- Description: A distinctive destination image is required in order to compete with other destinations for tourists and investors alike. This main objective of this study is to develop a model for destination image formation for Nelson Mandela Bay as a secondary economy to boost its global competitiveness. Several researchers have studied destination image and based on the fact that tourists and investors usually have a limited knowledge of destinations they have not previously visited, destination image fulfils an important function insofar as destinations with strong, positive, discriminatory and recognisable images. A literature study was conducted to identify the key influencers on destination image as well as to identify which forces are likely to influence the destination image of Nelson Mandela Bay. The different factors of destination image were identified from the literature sources and these factors provided a basis for an empirical study that was conducted amongst external stakeholders. The primary research objective was to create a model of destination image for Nelson Mandela Bay and to explain the cause and effect relationship between the dependent and independent variables. Added to the primary research objective, eight secondary research objectives were identified. The primary research question for this study was to identify what influences the destination image of Nelson Mandela Bay. Added to the primary research question, the researcher also identified eight research questions as part of the study. The empirical analysis was used to test the hypotheses and ultimately develop a model for destination image formation for Nelson Mandela Bay. This study was exploratory in nature and thus used a limited sample to gain insights for further research. Data were obtained through questionnaires that were distributed electronically to 120 respondents. This study concluded with the development of a destination image model for Nelson Mandela Bay that can be expanded upon with further research. The results indicate that general infrastructure and social environment; leisure and recreation; and culture influence the Affective component of Nelson Mandela Bay. Information sources and Political stability and risk influence the Cognitive component of Nelson Mandela Bay. Together the Affective and Cognitive component makes up the overall image of Nelson Mandela Bay.

- Description: The primary aim of this study was to determine whether a cricket specific visual skills training program has an impact on the visual performance of cricket fielders. The specific visual skills included accommodation, visual memory, speed of recognition, peripheral awareness, hand-eye coordination and saccadic eye movement. The study was exploratory and true-experimental in nature and utilized a quantitative approach. The pretest-posttest randomized group design was used. A total number of 20 participants that met the inclusion criteria were included in the study by means of purposive sampling. The 20 participants were randomly assigned to control (n=10) and experimental (n=10) groups. The experimental group underwent six-weeks of visual skills training. The tests used consisted of the Accumulator, Evasion, Corner Stretch and Flash tests on the Batak Pro, Hand-eye-coordination test, Hart Near Far Rock Chart and a Saccadic eye movement chart. Differences between the pre- and post-test scores were all positive and statistically (p<0.05) and practically (d>0.2) significant for the experimental group for the following visual skills tests: Hart Chart (M=7.90±3.73), Saccadic Chart (M=17.50±9.58), Accumulator (M=19.60±5.13), Corner Stretch (M=10.50±9.56) and Flash (M=5.40±3.75). The Evasion test (M=17.50±25.67) also showed a positive but insignificant improvement from pre- to post-test for the experimental group. The control group did not show any statistically significant improvements from pre- to post-test except in the case of Hart Chart (M=3.00±2.16) and Accumulator (M=2.40±2.55). Overall the experimental group produced significantly larger (p<0.05, d>0.20) pre- to post-test mean differences than the control group for six of the seven tests implemented. The Ball Toss test which was one of three hand-eye coordination tests did not show any significant differences between experimental and control groups even though the experimental group produced larger improvements. The other two tests that assessed hand-eye coordination (Accumulator and Corner Stretch) did, however reflect significant improvements for the experimental group. The findings of this study therefore revealed that improvements in visual skill performance of cricket players can be achieved through specific training.

Differences between the pre- and post-test scores were all positive and statistically (p<0.05) and practically (d>0.2) significant for the experimental group for the following visual skills tests: Hart Chart (M=7.90±3.73), Saccadic Chart (M=17.50±9.58), Accumulator (M=19.60±5.13), Corner Stretch (M=10.50±9.56) and Flash (M=5.40±3.75). The Evasion test (M=17.50±25.67) also showed a positive but insignificant improvement from pre- to post-test for the experimental group. The control group did not show any statistically significant improvements from pre- to post-test except in the case of Hart Chart (M=3.00±2.16) and Accumulator (M=2.40±2.55). Overall the experimental group produced significantly larger (p<0.05, d>0.20) pre- to post-test mean differences than the control group for six of the seven tests implemented. The Ball Toss test which was one of three hand-eye coordination tests did not show any significant differences between experimental and control groups even though the experimental group produced larger improvements. The other two tests that assessed hand-eye coordination (Accumulator and Corner Stretch) did, however reflect significant improvements for the experimental group. The findings of this study therefore revealed that improvements in visual skill performance of cricket players can be achieved through specific training.

- Description: Domestic labour is widely recognized as one of the most vulnerable labour sectors, both nationally and internationally. In South Africa, sectoral determination 7 was specifically developed to protect domestic workers’ rights and provide them with the means to negotiate with and hold employers to account. However, research over the past years has demonstrated that, while some areas of domestic labour have improved, many workers are still locked in exploitative labour relationships. This research shows that it may seem as if there are significant changes in this sector since the introduction of the sectoral determination, but paternalistic orientations, one-of-the-family myths, and food distribution suggest otherwise. The research concluded that continuities of exploitative and discriminatory practices are still prominent in the employment relationship when viewed through the lens of paternalistic care, food distribution, and the ‘one-of-the-family’ myth.

- Description: Irrigation farming is one of the most important rural development investments that can have both direct and indirect impacts on poverty and food security. The irregular and unreliable rainfall in the Eastern Cape Province has caused the smallholder farmers to deepen the irrigation farming systems as a strategy to cope with food shortage, income and poverty. South Africa has invested substantially in smallholder irrigation to benefit smallholder farmers in the less developed areas. Although the investment on small scale irrigation was to improve the welfare of the people, the performance and welfare impact of smallholder irrigation schemes has been poor and fall far short of the expectations of many stakeholders. The broad objective of the study was to examine the contribution of smallholder irrigation scheme on rural livelihoods of smallholder farmers at the project area. The null hypothesis was that smallholder irrigation schemes have no impact on farmer’s livelihoods. The alternative hypothesis for this study was that Melani irrigation scheme is contributing in improving rural livelihoods of smallholder farmers in the area. Cross study research design was used in the methodology. The purposive sampling was applied in order to choose a sample of 107 respondents that were interviewed using questionnaires, including both irrigating and non-irrigating farmers. A multiple linear regression analysis was used to find out whether the performance of the two groups of farmers is different and to what extent. To determine the specific role of irrigation an Independent T-Test was ran. Out of the selected sample 68 percent of households were farmers, 7.5 percent informal employed and 27 percent unemployed. It was found that the majority of participants were males and were uneducated. They depended on social grants for a living. The findings from the study showed that 84 percent of the respondents agreed that there is no market available in the village and farmers had limited access to credits. The crop income was the most contributing factor to household income. The results showed that whether the farmer is a non-irrigator or an irrigator the performance is not significant. Irrigation scheme improvement attained by smallholder farmers need to be maintained.

- Description: The aim of this study was to investigate the effect of visual skills training on the visual ability of elite rugby players. This study utilized a quantitative approach; and it employed a true experimental study design, in particular a pre-test-post-test randomized-group design. A total number of 26 participants (that met the specified criteria) were selected from the Eastern Province Rugby Academy squad. Those that met the criteria were then divided randomly into two groups (13 per group), which comprised the experimental and control groups, respectively. The control and experimental groups were tested on six visual skills, namely: accommodation, saccadic eye movements, speed of recognition, hand-eye co-ordination, visual memory and peripheral awareness. An optometric assessment was also conducted as a pre-test to ensure that the participant had “normal vision”, followed by a six week intervention (visual skills-training). The sessions were performed for thirty minutes three times per week for six weeks, followed by a post-test. Descriptive statistics were employed, both numerically, such as the mean standard deviation, and graphically by means of histograms. Inferential statistics were also used in the form of t-tests and Cohen’s d calculations to determine the statistical and practical significance of the mean score differences between the experimental and control groups. The pre- to post-test results indicated both statistical and practical significant differences in each of the visual skills tested among the experimental group; accommodation (hart near far rock test, p<.0005, d=2.34), saccadic eye movements (saccadic eye movement test, p<.0005, d=2.08), hand-eye coordination and peripheral awareness (accumulator test, p<.0005, d=2.20), speed of recognition (evasion test, p<.0005, d=1.14) and visual memory (flash program test, p<.0005, d=1.20). However, there were no statistically significant differences (p>.05) found when comparing the pre- and post-tests for the control group. It was concluded that the visual skills training program used had a significant positive impact on the visual performance of the Eastern Province rugby academy players.

- Description: The term “eco-city,” and similar concepts such as “green” and “sustainable” cities, has evolved over time concurrent to the development of the understanding of social change and mankind’s impact on environmental and economic health. With the advent of climate change impacts, modern economies developed the green city policy to create sustainable urban development, low emission, and environmentally friendly cities. In South Africa municipalities, including Buffalo City Metropolitan Municipality (BCMM) have been tasked to develop and implement the green city policy. However, BCMM is yet to develop the green city policy that clearly articulate how the municipality will combat climate change and reduce its GHG omissions in its spatial planning designs.

- Description: This research explores the use of the versatile 4,4-difluoro-4-boro-3a,4a-diaza-s-indacene (BODIPY) dyes and the modification of their spectroscopic properties. The synthesis of a tetramethyl-BODIPY bearing a sterically hindered meso-phenyl ring with an ethynyl functional group at the para-position was compared to that of its freely rotating counterpart with no methyl substituents on the BODIPY core, with the fluorescence properties in particular proving to be markedly different. These phenyl-ethynyl-substituted BODIPYs were used as the starting materials for the synthesis of novel BODIPY dyes for sensor applications via Sonogashira coupling reactions at the ethynyl position, but this resulted instead in the serendipitous synthesis of a novel BODIPY dimer in which the para-positions of the meso-phenyl rings are linked by a diethynyl bridge. Following iodination at the 2, 6-positions, the dimer was found to have a singlet oxygen quantum yield of 0.88, compared to the value of 0.86 that was obtained for the analogous monomer. Since the εmax values for the main spectral bands of the dimers are significantly higher, the compounds may be of interest for singlet oxygen generation applications. A second study was carried out on the interaction between methyl ester functionalized BODIPY dyes and upconversion nanoparticles (UCNPs) to explore the possible use of BODIPY-UCNP conjugates in biomedical applications. The singlet oxygen generation properties of the BODIPY were tested following iodination at the 2, 6-positions, a singlet oxygen quantum yield value of 0.86 was obtained. Three sets of oleate capped UCNPs were synthesized with different diameters and were rendered water dispersible with the addition of a silica shell. The necessary scaffolding for conjugation to the BODIPY was provided by amine groups following functionalization of this shell. All of the sets of oleate capped and silica coated UCNPs were characterized by transmission electron microscopy (TEM) and X-ray diffractometry (XRD) and their emission properties were studied upon excitation at 978 nm with a diode laser with a Picoquant Fluotime 300 spectrophotometer that enables the measurement of anti-Stokes emission. The potential utility of UCNP-BODIPY conjugates for singlet oxygen applications, such as PDT, was then assessed.

- Description: Call centres can be regarded as one of the most stressful working environments, where a number of challenges are experienced, such as a high staff turnover and a high level of absenteeism. Call centres have evolved over the past decade and will continue to evolve as technology progresses. The call centre industry, has experienced approximately an eight percent growth from 2013 to 2014 in terms of job creation within the Western Cape. The number of jobs increased from 38 000 to 41 000 year on year with a R9 billion contribution being made to the provincial gross domestic product. In investigating the call centre industry in the Western Cape, a core problem was identified which revealed a number of questions. Call centre agents experience low levels of satisfaction, mainly as a result of the repetitiveness and monotonous nature of their work. This leads to the main research problem, namely that of improving employee engagement within a contemporary call centre in the Western Cape. In order to resolve this problem, employee engagement need to be defined as well as various levels of engagement needed to be investigated. Furthermore, an understanding of the key drivers of engagement as well as an understanding on how employee engagement can be improved, is needed. This study aims at providing call centre managers with insight into various engagement factors which could impact on: absenteeism, attrition rates and performance of call centre agents as well as customer experience. In order to address the problem and answer the various questions described above, the researcher conducted a literature review in order to create an understanding of the employee engagement concept as well as identify the various levels of employee engagement and the key drivers of engagement. Based on the literature review conducted, a hypothesis was developed on key drivers that impact the engagement of call centre agents. The key drivers in accordance with the hypothesised model are communication, team support, autonomy, management support, rewards and recognition as well as career development. A further literature review was conducted on how to improve employee engagement based on the key drivers identified. Based on the literature review done a questionnaire has been constructed in order to test the hypothesis. Electronic surveys based on the questionnaire constructed were sent out to a sample of call centre agents. All results from the survey were captured onto excel spreadsheets and various statistical calculations were conducted. The results from empirical study were analysed in conjunction with the literature in order to address the objective of the research. The biographical statistics showed a greater composition of female respondents in comparison to male. The predominant age group was found to be 26-35 years and the predominant period of service towards the organisation was more than 3 years. Descriptive statistics per variable revealed a number of high positive indicators such as regular communication and relationships with managers as well as a sense of belonging in a team. The descriptive statistics also revealed various areas of concern of which the highest frequency of negative responses related to employees feeling like a professional associate and not just a simple worker as well as growth opportunities. All drivers in accordance with the hypothesised model, were positively correlated to employee engagement. The empirical research was conducted on a call centre within the Western Cape and thus it can be concluded that an improvement in the drivers of engagement should lead to improved employee engagement within a contemporary call centre in the Western Cape.

- Description: As human resources become part of strategic management in many organisations, employees are said to play a crucial role in helping their organisations fulfil their goals. It is a fact that organisations are now relying heavily on the competence of their human resources to gain a competitive edge over their competitors. It is therefore important that organisations should have employees that are committed and motivated in order to be able to compete. This study seeks to improve organisational commitment of the employees in the maintenance section of the selected telecommunications company, by investigating whether variables such as appreciative leadership, organisational citizenship behaviour, psychological empowerment (as measured by perceived control, perceived competence and goal internalisation), job satisfaction and employee rewards are significantly or not significantly related to the organisational commitment of the employees in the selected company. A sample, consisting of 120 employees, including technicians, supervisors and managers, was selected. The study achieved a response rate of about 52% (51.7) after 120 questionnaires were distributed. The empirical results of the study showed that only psychological empowerment (as measured by goal internalisation) and job satisfaction were significantly related to organisational commitment of the employees of the selected company. The implementation of the recommendations of this study should contribute to increased organisational commitment in the selected company.

- Description: Human African trypanosomiasis (HAT) is a public health problem in sub-Saharan Africa, with approximately 10,000 cases being reported per year. The Macrophage Migration Inhibitory Factor (MIF) which is encoded by a functionally polymorphic gene is important in both innate andadaptive immune responses, and has been implicated in affecting the outcome and processes of several inflammatory conditions. A recent study in mice to that effect showed that MIF deficient and anti-MIF antibody treated mice showed lowered inflammatory responses, liver damage and anaemia than the wild type mice when experimentally challenged with Trypanosomes. These findings could mean that the transcript levels and/or polymorphisms in this gene can possibly affect individual risk to trypanosomiasis. This is especially of interest because there have been reports of spontaneous recovery i.e self-cure/resistance in some HAT cases in West Africa. Prior to this discovery the general paradigm was that trypanosomiasis is fatal if left untreated. The aim of this study was to gain insights into how human genetic variation in forms of nonsynonymous SNPs affects the MIF structure and function and possibly HAT susceptibility. NsSNPs in the mif gene were obtained from dbSNP. Through homology modeling, SNP prediction tools, protein interface analysis, alanine scanning, changes in free energy of folding, protein interactions calculator (PIC), and molecular dynamics simulations, SNP effects on the protein structure and function were studied. The study cohort comprised of human genome sequence data from 50 North Western Uganda Lugbara endemic individuals of whom 20 were cases (previous HAT patients) and 30 were controls (HAT free individuals). None of the 26 nsSNPs retrieved from dbSNP (July 2015) were present in the mif gene region in the study cohort. Out of the eight variants called in the mif coding region there was only one missense variant rs36065127 whose clinical significance is unknown. It was not possible to test for association of this variant with HAT due to its low global MAF that was less than 0.05. Alanine scanning provided a fast and computationally cheap means of quickly assessing nsSNPs of importance. NsSNPs that were interface residues were more likely to be hotspots (important in protein stability). Assessment of possible compensatory mutations using PIC analysis showed that some nsSNP sites were interacting with others, but this requires further experimentation. Analysis of changes in free energy using FOLDX was not enough to predict which nsSNPs would adversely affect protein structure, function and kinetics. The MD simulations were unfortunately too short to glean any meaningful inferences. This was the first genetic study carried out on the people of Lugbara ethnicity from North Western Uganda.

- Description: Chronic non-communicable diseses are a global public health challenge that continuously threatens the development and health of humans. Risk factors such as unbalanced diet-the high consumption of processed food or food from animal origin are responsible for NCDs. NCDs result in weakened immune system, making the host susceptible to opportunistic infections. Thus, the NCDs burden is most times chronic and multiple with the illness and suffering of the affected person numerous. The lack of cure for NCDs, the high cost of drugs, their high side-effects, and the emergence of multiple drug resistance has given rise to the investigation of other sources for therapeutic cure such as medicinal plants. The ethanol, n-hexane and ethyl acetate extracts of Olea europaea were analysed for their antioxidant and antimicrobial activities. The essential oil was also analysed for their chemical constituents. The n-hexane extracts of O. europaea exhibited no inhibition against all of the microorganisms tested, while the ethyl acetate and ethanol extracts exhibited inhibition, with minimum inhibitory concentration values between 0.625 mg/ml to 1.25 mg/ml. The ethanol leaf and ethyl acetate stem extracts exhibited significant activity in the inhibition of 2, 2-azinobis-(3-ethylbenzothiazolin - 6-sulfonic acid diammonium salt (ABTS) free radical, the n-hexane leaf extract had the overall significant lipid peroxidation inhibition activity, while in the inhibition of 2, 2- diphenyl-1-picrylhydrazyl radical (DPPH), the ethanol and ethyl acetate leaf extracts had strong activity. Nonanal, phytol, α-Pinene, α-Phellandrene, spatulenol and farnesol were some of chemical components identified after the GC-MS analysis of O. europaea oil. In the final part of the dissertation, Euryops brevipapposus essential oil was assessed for the antioxidant activities using free radical scavenging assays. In addition to this, the antimicrobial activities were assessed and the chemical composition was analysed using GC-MS. The essential oil demonstrated significant antioxidant activity against 2, 2-diphenyl-2-picryl-hydrazyl free radical (DPPH), 2, 2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and lipid peroxides with IC50 value of 0.0000000671 mg/ml, 1.05 mg/ml, and 1.170 mg/ml respectively. The essential oil also showed significant activity against all microorganisms tested with minimum inhibitory concentration (MIC) values between 0.055 mg/ml to 0.5 mg/ml. α-pinene, α- Phellandrene, germacrene D, β-pinene, trans- β.-Ocimene, bicyclogermacrene and β -Phellandrene were some of the chemical compounds identified in E. brevipapposus oil. The study has shown that E. brevipapposus and O. europaea are abundant in phytochemical compounds which were thought to be the root cause for the activities demonstrated. Therefore, these therapeutic properties observed validate and elucidate the traditional usage of the both plants in the treatment /management of diseases.

- Description: Hepatitis E virus-mediated infection is a serious public health concern in economically developing nations of the world. Globally, four major genotypes of HEV have been documented and the swine HEV identified to date in different countries belongs to either genotype 3 or 4. It has been reported to cross species barrier and cause infections in humans. Hence, Hepatitis E has been suggested to be zoonotic owing to the increase of evidence through various studies. Thus far, genotypes 1 and 2 are exclusively found in human population. However, little data are available regarding the occurrence of HEV in South Africa, especially in the Eastern Cape Province. Hence, this study was designed to assess the prevalence of Hepatitis E Virus among swine herd in selected communal and commercial farms in the Eastern Cape Province of South Africa. A total of 160 faecal samples were collected from swine herds in Amathole and Chris Hani District Municipalities of Eastern Cape Province and screened for the presence of HEV. Faecal samples were collected, using sterile swabs, from swine between the age of 2 to 6 months old, placed on ice and transported to the laboratory for further analysis. Viral RNA extraction was carried out followed by nested reverse-transcriptase polymerase chain reaction was used for amplification, after which the amplified products were examined by electrophoresis and viewed under ultraviolet illumination. The positive PCR products were sent for sequencing. Of the 160 faecal samples screened, only seven were positive (4.4percent) for HEV. The nucleotide sequence analyses revealed isolates UFT 01-03 sharing 82percent to 99percent identities with other strains with accession numbers KX896664, KX896665 and KX896666 and UMCF 01-04 with KX896667, KX896668, KX896669 and KX896670 from different regions of the world Phylogenetic analysis also showed that all seven isolates from this study clustered with both human and swine HEV from different geographical regions of the world especially with Japan Human and swine strains, Netherland swine HEV strains (AY032758, AF332620) and human HEV strain from France (JQ763611). We conclude that HEV is present among swine in the Eastern Cape Province, albeit in low incidence, and this does have public health implications. There is need for maintenance of high hygienic standards in order to prevent human infections through swine faecal materials and appropriate cooking of pork is highly advised.
