- Description: Carnivore intra-guild interactions can be important drivers of carnivore community composition and ecosystem functioning. Large carnivores are particularly important since they occupy the highest trophic levels and can exert extensive influences on subordinate carnivores and prey species. Given Africa’s rapidly expanding human population, enclosed reserves such as those found in South Africa, may become increasingly important for carnivore conservation. A major concern, however, is that the interactions and co-existence of multiple carnivores in these systems is poorly understood. Additionally, the majority of reserves in South Africa are small ( 400km²), potentially increasing the likelihood of competition. My research aimed to provide insight into the interactions and co-existence of a multi-carnivore community within a small, enclosed reserve in South Africa (Selati Game Reserve). I tackled this task by using a combination of field techniques including camera trap surveys, ungulate transect surveys, aerial count surveys, location data collected from collared large carnivores and scat and kill site analyses. I found that carnivore-carnivore interactions, and their associated impacts, varied within the carnivore guild and that co-existence may be due to trade-offs between various risks (i.e. interference and exploitative competition) and benefits (i.e. resources such as food and space). My findings also revealed that large carnivores, such as lions (Panthera leo), spotted hyaenas (Crocuta crocuta) and leopards (Panthera pardus) do not have homogenous effects and that site-specific research on multiple-carnivores is integral for conserving biodiversity and ecosystem dynamics. Lions were the dominant large carnivore (in terms of intra-guild predation, space use and resource use) despite being outnumbered seven to one by spotted hyaenas. Leopard occupancy was negatively influenced by lions and leopard diet overlapped almost completely (91%) with spotted hyaenas, suggesting increased kleptoparasitism of leopard kills by spotted hyaenas. While my study provides valuable insight into the complexity of carnivore intra-guild competition in a small, enclosed reserve it also highlights major research gaps and emphasises the need for ecosystem-based research throughout southern Africa to fully understand how multiple sympatric carnivores co-exist in these systems.

- Description: The significant positive relationships between workplace spirituality and organisational citizenship behaviour, as well as between centrality of religiosity and oganisational citizenship behaviour among police officers, confirm the relevance of social exchange theory and affective events theory to police officers’ behaviour. This study confirms the applicability of Social Exchange Theory (SET) and Affective Events Theory (AET). The current study utilized the SET and AET to examine the correlation between workplace spirituality and centrality of religiosity as well as organisational citizenship behaviour among Police officers in the Raymond Mlaba Local Municipality of the Eastern Cape. There is limited previous research concerning the influence of workplace spirituality and centrality of religiosity on organisational citizenship behaviour among police officers in the South African Police Services (SAPS) Department. A quantitative cross-sectional survey was conducted. The sample (N= 100) consist of Police officers from Raymond Mhlaba Local Municipality Police stations. Data were collected through the questionnaire method and SPSS was used for data analysis. A correlational analysis coupled with a simple linear regression analysis was utilised to determine whether there existed any significant relationship with the study’s theoretical attributes. The results of the simple linear regression indicated that workplace spirituality is positively correlated with organisational citizenship behaviour; which is similar to the centrality of religiosity. The results from multiple linear regression showed that the centrality of religiosity does moderate the correlation between workplace spirituality and organisational citizenship behaviour. The results of Multiple linear regression also showed that Workplace spirituality and centrality of religiosity both account for an extensively higher proportion vi of variance in organisational citizenship behaviour than in any of the two variables. This study augments existing knowledge on workplace spirituality, the centrality of religiosity and organisational citizenship behaviour among Police officers in the Raymond Mhlaba Local Municipality, which has largely been ignored by previous researchers, validates certain aspects of the SET and AET. The Station Commanders or Captains should give consideration on how to make the workplace more conducive to the centrality of religiosity and workplace spirituality; so that the Police officers can increase their organisational citizenship behaviour. Strategies need to be implemented to improve managerial and coworker support for Police officers through socialization and team building activities. However, to overcome feelings of occupational stress and their effects on well-being, employers should provide adequate information on any changes in the police service that may entail excessive work demand and dangerous working conditions.

- Description: Education is imperative for the economy and for the employment of the youth, particularly given the high levels of youth unemployment in South Africa. The introduction of Tourism as a school subject is perceived as a gateway to employment opportunities for unemployed people and as a means to stimulate the economy of the country. Educators, especially in South African township schools, often teach in less favourable conditions and experience many challenges which require innovative solutions. This study contributes to an understanding of the challenges faced by educators teaching Tourism, especially educators teaching in township areas in the Nelson Mandela Bay district. Of particular importance is the coping strategies used by these educators to innovatively deal with these challenges. This purpose of the study was therefore to investigate the challenges experienced by educators that teach Tourism at township high schools in two Circuit Management Centres (CMC) in the Nelson Mandela Bay district in Port Elizabeth. A qualitative research design was followed with interviews as the empirical data collecting tool. The sample consisted of 16 educators teaching Tourism to Grade 11 and 12 learners at selected schools. The data collected was analysed qualitatively, using thematic analysis. The findings of this study revealed many challenges experienced by educators of Tourism at township schools in the Nelson Mandela Bay district. The key challenges for educators related to resources, learners, the system, teachers and infrastructure. The results revealed that the educators used a variety of coping techniques to deal with these challenges. The researcher makes recommendations to the different stakeholders in education to address these challenges, as well as make suggestions for future research.

- Description: Crime has been prevalent in South Africa, particularly in Port Elizabeth where violent crimes such as attempted murder, murder, sexual offences, robbery and hijacking have been reported to the South African Police Service. These violent crimes are mostly prevalent in police precincts such as Gelvandale, Bethelsdorp, Kwazakhele, New Brighton and Walmer. As a result, development in these police precincts has been affected negatively. This is highlighted by how developmental issues such as poverty and unemployment have been ubiquitous due to the manner with which crime has an effect on development. ICT companies are continuously providing solutions to crime-related challenges. The emergence of new technologies, such as CCTV surveillance cameras, drones and facial recognition software have been proven to be a solution to combating crime in some developing countries in Africa. Thus, the purpose of this study was to examine the challenges of electronic surveillance in combating crime and addressing developmental issues in Port Elizabeth. The study found out that the developmental issues faced by communities in Port Elizabeth include unemployment, poverty, a high crime rate, substance abuse, and a lack of resources. In addition, the study concluded that, the lack of education and skills development, gangsterism, unemployment and poverty were amongst the main causes of crime in Port Elizabeth. The study also revealed that, the SAPS does not have enough electronic surveillance devices such as CCTV cameras installed in high crime areas, thus, recommendations were made on how electronic surveillance can be used to combat crime and address developmental issues

- Description: Background: The steady increase in deaths due to non-communicable diseases (NCDs) in South Africa is raising concern, as 63% of all deaths worldwide are attributed to NCDs and these diseases cause 36 million deaths each year, with 80 % of incidences occurring in low-and middle-income countries. In rural communities where income is increasing, the prevalence of NCDs are increasing as well. Due to the lack of NCD prevention and treatment in rural communities, it is expected that, if health promotion strategies are not implemented and socio-economic development in South Africa continues, there will soon be an uncontrollable NCD epidemic. It has been found that dietary risks affected people’s healthirrespective of their age, gender or residential sociodemographic development and that dietary improvement might prevent one in every five deaths worldwide.Aim:The aim of this study was to determine the factors that influence the perceptions and behaviour in a rural community with a low socio-economic status regarding dietary habits and to use the knowledge to formulate an effective dietary modification strategy.Designand methodology:For this study,action research with a quantitative and qualitative component was followed.The quantitative component focuses on measureable aspects, and the qualitative component focuses on meaning. Data was collected following the standard operating procedure for anthropometry, blood pressure and blood glucose. Further methods used were questionnaires, 24-hour dietary recalls and focus group discussions. Data were analysed using Microsoft Excel, FoodFinder3 and other calculations.Sample and setting:A convenience sample (n = 16) wasused and this study was undertaken on request of the non-governmental organization, Karoo Angels and included all participants who earn an income and who do not work for themselves, that were willing to participate and living in Rietbron and Vondeling, in the Sarah BaartmanDistrict in the Eastern Cape. Results:Weight changes took place, both the crafters in the mild thinness category gained weight, one gained 3.9 kg and the other 0.5 kg. The three crafters in the normal category did not have to gain or lose weight, but all three ofthem gained an average of 3.6 kg. For the group who had to lose weight, no statistically significant weight change took place from before the intervention (76.08 ±17.67 kg) to after the intervention (75.81 ± 17.81 kg, t(10) = 0.692, p = 0.505). The maximum weight lost ivwas 3.1 kg and the maximum weight gained was 3.2 kg. Changes took place regarding BMI, waist circumference, waist-to-hip ratio and neck circumference. Some positively changed their BMI status.After the implementation of the intervention, there was a slight decrease in frequency of alcohol consumption, but smoking and physical activity remained mostly the same. Hypertension was the most prevalent NCD and is linked to smoking and alcohol consumption which is prevalent in this study. Fruit and vegetable consumption is low, and a slight increase in consumption was evident. A maximum dietary diversityscore of seven and minimum of two, where the mean was 3.81was found. The crafters’ diet did not meet the DASH diet recommendation,the mean energy distribution is of all macronutrients differ with ±4% and none of the participants’ mean micronutrients intake met the recommendations of the DASH diet or RDA. Factors that prevent them from reaching their goals included low income, low availability of fruit, vegetables and transport and no storage for food.Conclusion:It is important to consider the individuals’ living conditions, resources, knowledge, motivation and social group. The environment and resources available have a significant impact on the lifestyle of the individuals. Directing efforts of behaviour change to increase dietary diversity as the main objective, might be a more efficient way to change behaviour.Recommendations:Future studies should consider doing this study over a longer time period. The involvement of a psychologist would also be beneficial to assist the process of behaviour change.

- Description: An underdeveloped aspect of academic staff development research in higher education is using theory to help academic lecturers to understand and inform their practices, so as to better enable student development and learning. This chapter illustrates how a theorized way of talking about teaching and learning, specifically using the LCT dimension of Semantics, both semantic waves and the semantic plane, may create exciting and productive conversations with academic lecturers. Using two ‘vignettes’ drawn from English Studies and Political Studies, the chapter illustrates how teaching practice and curriculum design can be enhanced by using LCT in academic staff development work, and by extension in curriculum design, teaching and assessment practice.

- Description: Plasmodial transketolase (PTKT) enzyme is one of the novel pharmacological targets being explored as potential anti-malarial drug target due to its functional role and low sequence identity to the human enzyme. Despite this, features contributing to such have not been exploited for anti-malarial drug design. Additionally, there are no anti-malarial drugs targeting PTKTs whereas the broad activity of these inhibitors against PTKTs from other Plasmodium spp. is yet to be reported. This study characterises different PTKTs [Plasmodium falciparum (PfTKT), Plasmodium vivax (PvTKT), Plasmodium ovale (PoTKT), Plasmodium malariae (PmTKT) and Plasmodium knowlesi (PkTKT) and the human homolog (HsTKT)] to identify key sequence and structural based differences as well as the identification of selective potential inhibitors against PTKTs.

- Description: This thesis is focussed on Margaret Atwood’s MaddAddam trilogy: Oryx and Crake (2003) The Year of the Flood (2009) and MaddAddam (2013). Detailing Atwood’s own specifications as to why these texts should be categorised as works of speculative fiction, the thesis examines how this literary genre, and Atwood’s MaddAddam trilogy in particular, is uniquely capable of encouraging readers to interrogate critically the socio-economic, environmental, and ethical problems to which she, and the contemporary reader, bear witness in the present technological age. With reference to Atwood’s essays and critical writings, Darko Suvin’s Metamorphoses of Science Fiction, and Wolfgang Iser’s The Act of Reading, this project explores the value of reading speculative fiction and details how Atwood has constructed the fictional, yet plausible, possible future world of her trilogy by extrapolating our current scientific capabilities, environmental challenges, and political configurations to their logical conclusions. It explores the close relationship that exists between the near-future world of Atwood’s texts and the contemporary context from which she has drawn her subject matter, and argues that the trilogy demonstrates graphically the long-term consequences of capitalism, sustainability, and the doctrine of human exceptionalism, which this project, following Yuval Harari, defines as orthodox guiding narratives: fictions that humanity has created, and which structure our perception of reality and guide our behaviour. The project maintains that Atwood’s trilogy presents the reader with a hypothetical future that looks towards and beyond the end of contemporary technological society in order to urge her reader to imagine, and actualize, alternatives to the scenarios that these texts depict. The most significant question Atwood’s texts ask is whether contemporary technological society is willing and able to transform in order to avert the ecological apocalypse that is the logical conclusion to the Anthropocene?

- Description: Elemental fluxes to the ocean are expected to increase with the surface area of continental exposure to weathering and atmospheric PCO2. The record of phosphorus in sediments, which has no notable source within the ocean, and the radiogenic strontium isotopes in Archean carbonates indicate that, prior to the Great Oxidation Event (GOE), subaerial expanses represented only about 20% of the modern continental surface area, i.e. 7% of the surface of the Earth. Because these simple first-order observations, in contrast to the low oxygen content of the pre-GOE atmosphere, have so far received only little attention in the appraisal of the marine chemistry of the early Earth, a reassessment of the chemistry of the pre-GOE ocean is warranted. Here we discuss some of the geochemical cycles of the Archean world, including protons, alkalinity, electrons, and other electrolytes, and attempt to build a first conceptual framework for Chemical Archeoceanography.

- Description: In the present study, we evaluated the phytochemical compounds and antioxidant properties of chloroform, ethanol and acetone extracts for leaves and flowers of Leonutus leonurus (L. leonurus) alongside with their cytotoxic effects on human cervical carcinoma (HeLa) cell lines. The phytochemical compounds present in the leaves and flowers of L. leonurus included; phenolics, flavonoids and alkaloids. Their radicals scavenging effects against 2, 2-diphenyl-1-picrylhydrazyl [DPPH] 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulphonate) [ABTS·+], hydrogen peroxide, nitric oxide as well as metal chelating activities showed dose-dependent activities. Gas chromatography-mass spectrometry (GCMS) analyses revealed the presence of important bioactive compounds, which are associated with antioxidant; and the extracts exhibited toxicity effect against HeLa cells. The findings from this study divulge extracts of L. leonurus as prospective sources of antioxidant and anticancer agents; and hence, further study on their neuroprotective potentials becomes imperative.

- Description: Child marriage is defined as any marriage where one of the spouses is younger than 18 years old. A number of deep, complex, interrelated and interlinked factors are responsible for the practice in Zimbabwe and elsewhere. These include the weak enforcement of existing laws, legal contradictions, slow alignment of laws to the Constitution and international child rights, entrenched harmful religious and cultural practices, and acute poverty. It was at the fulcrum of this dissertation thus to examine the unfair limitations caused by child marriage, on the realisation and enjoyment of child rights in Zimbabwe. The United Nations International Children’s Emergency Fund reported an estimated 31 percent prevalence of the scourge in the country. These percentages translate to millions of children, and the numbers could be on the rise. Child marriage has intense consequences for the realisation and enjoyment of rights by many children in Zimbabwe. Of note, child marriage ends childhoods. It impairs the children’s right to education, minimises their economic opportunities and fair chances in life, and increases their vulnerability to domestic violence, marital rape and sexually transmitted diseases. The grave ramifications of child marriage, in terms of the realisation of child rights have led to a number of international, regional and national efforts to curb this scourge. However, owing to an array of multifaceted and complex causes, the practice remains highly prevalent in Zimbabwe. After decades of side-lining, child rights in Zimbabwe, have finally gained constitutional protection under the 2013 Constitution. While the comprehensive protection of child rights as justiciable rights is an acceptable standard, a plethora of practices such as child marriage are a practical and real threat to the realisation of these rights. Therefore, it is incumbent upon Zimbabwe to ensure that child rights as stipulated in the Constitution are respected, promoted, protected and fulfilled. The elimination of child marriage is a daunting yet possible task. Through desktop based qualitative research, this dissertation ascertained the main drivers of the practice in the country, and its impact on the realisation of fundamental child rights in Zimbabwe. The study further explored the contribution, as well as the insufficiencies of International and African Human Rights systems, to the protection of children from child marriage. It also assesses the prospects and challenges of the existing domestic (legislative and constitutional norms) in protecting child rights in the Southern African country. The impetus behind this iii examination is to recommend a comprehensive and holistic effort to curb child marriage and suggest a consolidated legal and non-legal approach to end it

- Description: This mini-thesis has developed as a practice-based supporting document to the exhibition Chirema Chine Mazano Chinotamba Chakazendama Madziro. The exhibition responds to how people become innovative in finding alternative means of survival and staying relevant in an economically depressed country. Zimbabwe is often the first country that comes to mind when people talk about hyperinflation; the situation was and still is intolerable, but somehow its citizens find means to pull through. Unemployment and poverty are the main causes of physical and mental problems for an individual. With this thesis, I highlight the innovations employed by Zimbabweans as a way of keeping themselves busy. I approach this through analysing the Zimbabwean general public’s creative reactions, and by tracing Zimbabwean visual artists’ use of found objects as a reaction to the country’s economic hardships. As people have been pushed to find alternative ways of survival, Zimbabwean artists in particular also shifted from using conventional art materials due to their unavailability. They began to redefine what art material is by employing objects in their artworks that previously had a non-art function. As such, there is a growing need to recognise, classify and document the shifts and establish platforms to generate growth of these innovations. In this minithesis I discuss my own practice, and I analyse the works of Moffat Takadiwa, Gareth Nyandoro and Serge Attiku Clottey.

Choreographies of protest performance as recruitment to activism and the movement of perception during the 2015 re-emergence of student activism at Rhodes University

- Description: It has been argued that individuals participate in activism due to an identification with the preferences and interests of an emerging group of actors or in solidarity with a pre-existing network that has resorted to a number of protest repertoires in order to make claims or demands. Additionally, an emerging instance of protest is often linked to an image of previous protest events through the employment of a combination of master frames which function as discursive articulation of the encounter in familiar terms, creating a frame resonance which recruits adherents and constituents. To understand why some bystanders to protest transcended to actors in protest and the development of frames within a protest cycle, a performance ethnography is employed to observe and analyse choreographies of protest which took place at an institution of higher education in South Africa during the 2015 re-emergence of wide-spread student activism. It is found that in encountering an atmosphere of protest there emerged a relation of feeling, referred to as “feeling the vibe or atmosphere”, which those who became protest performers resolved in ways which increased their capacity to act in favour of co-constituting that atmosphere. During the encounter between the bystander body and the atmosphere of protest, non-linear somatic communication, characterised by active and passive gestures and postures, occurred through which protest performers developed contact and connection with other bodies as a result of the displacement of space. This thesis suggests that participation in activism can be about going with the flow of movement in an uncertain and ambiguous moment and is not limited to an identification with the pre-existing organization of preferences and interests as a frame of resonance emerges to signify somatic communication which differentiated bodies in the duration of protest performance. Therefore, this thesis uses the theory of affect to situate student activism in-between the politics of performance and the performance of politics whereupon the rhythm of song creates an opening for the kinaesthetic to create form from spontaneous movement of the body as an event of the movement of perception and the perception of movement.

- Description: Brazilian pepper (Schinus terebinthifolia) is a tree native to subtropical South America that was introduced into South Africa in the early 1900s as an ornamental plant. The tree has since escaped cultivation and has invaded ruderal and pristine habitats along the eastern coast of South Africa. Brazilian Pepper is also one of the most problematic invasive alien plants in Florida, USA. We modelled the climatically suitable area for this species in South Africa using MaxEnt, with five distinct datasets: incorporating both the native and the invaded range of the species, as well as different backgrounds.

- Description: The purpose of this paper is to outline the climate responsive innovation process within the agricultural innovation system of the North West Province, South Africa. The focus was on the embedded curriculum and learning activity system and its responses to social-ecological and earth system changes influenced by climate change. It outlines the barriers and processes hampering curriculum and learning innovations towards climate-smart responsiveness, and also examines the processes required to initiate micro and macro innovations. This paper focusses on how actors within the system can initiate curriculum innovation and climate responsiveness through micro innovations when supported and how this can lead to macro innovations. The system experienced various barriers during the innovation process and overcame many challenges during the journey towards climate-smart responsiveness through the identification of contradictions within the system, developing tools to assist in the transitioning process and expansion in the social-spatial dimension by establishing a learning network within the surrounding communities. The research indicated that the catalysing of the curriculum and learning system required specific tools, time and the understanding of the importance of micro-level innovation.

- Description: The emergence of new ICTs over the past decades has had a substantial impact on commerce and to societies in general. However, the high costs and the relevant skills and expertise that are associated with the implementation and maintenance of the latest ICTs impedes SMEs from taking full advantage of their use. The introduction and adoption of cloud computing has addressed some of these challenges for SMEs. Despite this, SMEs in rural South Africa have not fully adopted or realized the advantages of cloud computing, which could be owing to a number of factors.The aim of this study was to explore how rural SMEs in the Eastern Cape Province of South Africa can leverage on the capabilities of cloud computing for competitive advantage. The study adopted an interpretivist, quantitative approach to identifying the enablers and barriers of cloud computing adoption. The research population was defined as all the SMEs that operate outside of Buffalo City and Nelson Mandela Bay Metropolitan Municipalities. Convenience and snowball sampling techniques were used as non-probability sampling methods. Data was collected from the participants using a structured self-administered online questionnaire. The Technology-Organization-Environment framework was used as a basis in formulating the research theoretical framework, focusing on technological, organizational and environmental elements that could potentially influence adoption of cloud computing by rural SMEs. Microsoft Power BI was used to present demographic information as well as descriptive statistics for the factors included in the proposed research model. IBM SPSS 22 was used for correlation and linear regression analysis. The review of related literature revealed that access to markets, access to finance, inadequate public infrastructure and lack of skilled resources are some of the major challenges that rural SMEs face. This study found seven of the statistically examined factors to be significant predictors of cloud adoption by rural Eastern Cape SMEs. These are market demand, use of online-based marketing, having formal business plans, reliable electricity, awareness of SaaS, use of basic Internet-based services such as email and websites as well as Internet costs.

- Description: An inclusion complex of isoniazid-grafted phthalocyanine with gamma-cyclodextrin (Complex) was co-encapsulated with rifampicin (RIF) in crude soybean lecithin liposomes using a heating method. The encapsulation efficiency (%EE) of the Complex-RIF co-loaded liposomes (Rif-Complex-Lips) was determined using UV-Vis spectrophotometry. Rif-Complex-Lips formulations were evaluated using dynamic light scattering, transmission electron microscopy (TEM), 1H-NMR, absorption and emission spectroscopy. Dialysis was used for drug release study in two different media, pH 6.4 and 7.4. HeLa cells were used to assess potential cytotoxicity, and the uptake by lung fibroblasts and epithelial cells was investigated using fluorescence microscopy. The particle size and Zeta potential of Rif-Complex-Lips were approximately 594 nm and –50 mV. Spectroscopic analyses demonstrated molecular distribution of the cargo within the lipid core, and encapsulation efficiency of 58% for Complex and 86% for RIF. TEM analysis unveiled the existence of spherical nanoparticles in our samples, indicating the presence of liposomes. Rif-Complex-Lips exhibited much higher release rates for both INH and RIF at pH 6.4 compared to those tested at pH 7.4. In addition, there was no cytotoxicity on HeLa cells, but remarkable Rif-Complex-Lips internalization by peripheral lung fibroblasts and epithelial cells. Hence, Rif-Complex-Lips are promising vehicles for intracellular delivery of antimicrobial drugs.
