- Description: The purpose of this research study was to explore and describe the knowledge and the level of awareness of drowning risks amongst adolescents in the Nelson Mandela Metropole, Eastern Cape Province, and South Africa. Drowning is defined as the “process of experiencing respiratory impairment from either submersion or immersion into a water medium” (van Beeck et al 2005:853). Global statistics place drowning as being the third foremost cause of unintentional death worldwide (WHO 2013). The World Health Organization reports that more than 90% of the estimated 370 000 drowning fatalities recorded in 2012 occurred in low and middle income countries (WHO 2014). A qualitative descriptive explorative contextual design was employed in this research study. A non-probability convenience sampling method was used. Adolescents aged 10- 13 years old who attend a public primary school and model C primary school in Nelson Mandela Metropole area in the Eastern Cape Province were the target population who had the specific characteristics of interest and significance to the research phenomenon (Asiamah et al 2017). Four focus group interviews were conducted. The groups consisted of five to ten participants grouped together to discuss the matter. Field notes were also taken by the researcher on what was heard, observed, thought and experienced during the interview process (Streubert & Carpenter 2007). Ethical principles were maintained as well as the concepts of trustworthiness were applied throughout this study.Data analysis was done using Tesch’s approach to open coding in qualitative research. A total of six themes and seven sub-themes arose during the analysis of the data and were completely discussed. The findings suggest that most of the participants are quite aware and knowledgeable of the potential risks that predispose an individual to drowning. The consequences of what happens when a victim is exposed to drowning, however, requires more insight. The risk of being unsupervised as well as not being able to swim was echoed in most of the group interviews. vii A noteworthy finding was the fact that the participants who were involved with some form of water safety programme/s at school were very articulate in their responses to the questions. It was recommended that educational programmes ought to be aligned with current evidence which is reflective of the region’s demographics and dynamics. Even though all researchers do not share the sentiments that swim proficiencies heighten the safety of the individual in and around water, the need for ongoing research initiatives is a significant stimulus that will generate new evidence and inform current preventive strategies. Identification and awareness of drowning risks require a foundation of comprehension in order to better understand and interpret the consequences of these risks. Learn to swim or swim orientation initiatives could potentially assist at primary school level with the safety levels of learners.

- Description: Background: Food preparers and food handlers seem to face difficulties in identifying activities that render food unsafe as a result of food contamination during food preparation. Research has shown that food preparation is a global problem and a potential health risk which can result in food-borne diseases as a result of a lack of knowledge on the principles of hygienic practices and negative attitudes when handling food. Aim: This study aims to determine the knowledge, attitudes and behaviours that motivate food preparers in safe food preparation. Method: Building on existing work in understanding this phenomenon it asks: A purposive sample of male and female participants who prepare food at home were asked to complete a questionnaire. The questionnaire items were developed through focus group interviews and after a pilot study, presented to participants to complete. The items were subjected to principal component analysis (factor analysis), yielding a six-factor solution. The factor means, standard deviations were calculated and reliability was determined for each factor using Cronbach’s alpha as a measure of internal consistency. Group differences were determined through independent samples t-tests and anova. Results: The quantitative analysis demonstrated that food preparers have a fair knowledge and perception of how to prevent contamination. However, their behaviour is various aspects of food preparation might at times put them at risk for contamination. With regards to attitude, when comparing groups, people who prepare food with love and care demonstrated a more positive attitude towards food preparation than those who are less passionate to prepare food. On this basis, hygiene education should focus on the perceived threat to health as cues to action in changing attitudes and adherence to recommendations on hygiene. Conclusion: Further research is required to solicit the views of respondents below the age of 18 with regard to food-handling practices in pre-prepared food to ascertain and prevent further contamination and ensure food safety.

- Description: The dissertation examines the Ugandan labour dispute resolution system by undertaking an analysis of international labour standards and a case study of South Africa’s labour dispute system. The study pronounces the legislative provisions of the Employment Act and Labour Disputes (Arbitration and Settlement) Act that exist for the effective and efficient resolution of labour disputes through an alternative dispute resolution (ADR) system. The study contends for the provision of a proactive and expeditious dispute resolution system that helps to resolve labour disputes in the most effective and efficient manner, without necessarily having to resort to the courts. The dissertation further examines the provisions of relevant international labour standards on labour dispute resolution to ascertain their adequacy as part frameworks that apply to Uganda’s obligation to provide ADR systems that respond to the needs of the labour relations community. The study contends that ratifying particular ILO conventions creates obligations upon a country to comply and apply provisions of these conventions in national legislation. It is further argued that by having ratified those international labour standards that provide for ADR, Uganda assumes specific obligations under international law, enjoining the country to provide the required ADR system of conciliation and arbitration, which is reliable and trusted by the countries citizens. A case study of South Africa is adopted with the primary focus on whether Uganda can learn from South African’s ADR system which is arguably more effective and efficient. South Africa has a labour dispute resolution system that has influenced majority of the Southern African Development Community (SADAC) law, hence prompting this study to borrow its ADR system predominantly the Commission for Conciliation Mediation and Arbitration (CCMA). Despite the differences between Uganda and South Africa, the study also indicates fundamental similarities. Preferably, disputes should be resolved at conciliation level, resulting in the minority of disputes being referred to arbitration or the Industrial Court. This is far from the reality of the situation in Uganda. The study acknowledges that the Labour Disputes (Arbitration and Settlement) Act and Employment Act have put up provisions to establish a fast and effective labour dispute system, however, the gap exists at implementing these effective provisions in the Labour Disputes (Arbitration and Settlement) Act and the Employment Act. These lacunae in implementation make the attainment of an effective and efficient labour dispute resolution difficult. For this reason, the author proposes several remedial interventions in line with international labour standards and lessons from South Africa’s system that look to the future and the continued provision of fast, effective, and user-friendly ADR services. For Uganda to solve successfully apply these remedies, a strong political will as well as concerted efforts from all role players in the labour relations community is required.

- Description: The strengths of trophic interactions within ecosystems can be mediated by complex mechanisms that require elucidation if researchers are to understand and predict population‐ and community‐level stabilities. Where multiple prey types co‐occur, prey switching (i.e. frequency‐dependent predation) by predators may facilitate low‐density prey refuge effects which promote coexistence. On the other hand, lack of switching and strong preferences by predators can strongly suppress prey populations, which is especially important considering vector species such as mosquitoes.

- Description: Opuntia ficus-indica is a succulent plant species that originated from Mexico and parts of neighbouring middle-America and introduced in South Africa by white settlers in the eighteenth century. The species is now categorized as invasive in South Africa but has both commercial and non-market uses. This study evaluated the livelihood uses and local perceptions of O. ficus-indica of rural residents in Makana, Ngqushwa and Raymond Mhlaba Local Municipalities in the Eastern Cape province in South Africa. Data on the livelihood uses and local perceptions on the species in the study area were gathered through community focus group discussions and household surveys using semi-structured questionnaires between June 2018 and August 2019. A sample of 150 participants selected via snowball-sampling technique provided detailed accounts on utilization of O. ficus-indica in the study area. The importance of O. ficus-indica as a useful plant species was ubiquitously perceived, with all respondents reporting its contribution towards their livelihood needs and more than three quarters (88.0%) using the species on a regular basis. Majority of the respondents (41.0%) regarded O. ficus-indica as an important source of cash income while about a third (33.0%) regarded the species as an important source of food products and nutrition. Interviews with respondents revealed that O. ficusindica is currently being harvested from the wild with 73.3% of the respondents reporting that the abundance of the species was decreasing. The positive socioeconomic contributions of O. ficus-indica need to be taken into account when assessing the costs resulting from invasions caused by alien plant species. This study is a crucial starting point in trying to understand and initiate the management of alien invasive species such as O. ficus-indica. Results of this study are also important for understanding local peoples’ perceptions of new introductions and management of existing alien plants in the province.

- Description: South Africa is striving to attain quality equal education; however, this ideal is affected by various factors such as discrimination, learner-related challenges (e.g. dilapidated rural schools, poverty, and violence), educator-related challenges (e.g. low morale and motivation, and poor administration and management of schools), and governmental issues (e.g. a lack of will, lacklustre attitudes, and an inability to deliver resources and/or services). While the National Department of Basic Education is battling to eradicate the backlog of school infrastructure and maintenance, mud schools are still prevalent in rural areas. The present state of poverty-stricken areas is most affected by the mentioned challenges and, as a result, it is necessary to determine the nature and extent of the consequences in terms of academic performance. This study, therefore, investigated the reality of the current rural school situation by investigating the perceptions of learners on the effect of infrastructure development on their academic performance in public secondary schools. Three secondary schools in the Motherwell area in Port Elizabeth were chosen for the research setting. A quantitative research approach was deemed suitable for the study, and a questionnaire was utilised for data collection. A total of 151 questionnaires were completed. The key findings derived from the data indicated that inadequate infrastructure has a negative impact on academic performance. Some of the key issues pertaining to infrastructure included inadequate leisure areas, laboratories, libraries, and sport fields. Overcrowding in classrooms were also found to be prevalent, and posed a major barrier to learning. The findings of the study provided insights into the reality of rural education and were used as a basis for offering recommendations that may assist stakeholders to improve the current situation.

- Description: After almost 25 years of democracy in South Africa, not everyone has access to the same quality education. The responsibility of creating a literate society however cannot rely on the national government and schools alone, but instead needs to fall on the shoulders of various stakeholders. Volunteers in particular have an important role to play in remedying the current literacy crisis experienced in South Africa. This study takes the form of a case study approach and examines the experiences of Project Read literacy volunteers. A telephonic survey and two focus group discussions were conducted in order to determine who it is that volunteers for the programme; what prompts these particular individuals to volunteer; the perceived benefits of volunteering; and how volunteers report on their volunteering experiences. Although the Project Read programme is focused on the early literacy development of learners, volunteers seemed to undergo a developmental process themselves – something they had not anticipated at the start of their volunteering journey. This study illustrates the power of meaningful relationships in breaking down artificial categories and in bringing about important change with regards to the perceptions and attitudes of individuals towards community engagement. It is hoped that the data generated through this study will assist in recruiting and retaining more literacy volunteers through feedback to the NGO. In this way more children will be assisted to enhance their literacy competencies, from which they can build and achieve.

Given their size, individuality and disciplinary complexity, analysing doctoral dissertations is a complex task – one that makes defining exact rules for students to follow difficult, if not impossible. In order to open up access to increasingly diverse students, there is a need to make this tacit writing practice explicit. To do so requires a more detailed understanding of what doctoral writing involves. This chapter illustrates an approach that can provide such an understanding. Drawing on the concept of ‘semantic gravity’ from Legitimation Code Theory (LCT), the chapter focuses on a student’s progression from ‘raw’ data description to fully realized theoretical discussions of data. The findings demonstrate how, through the drafting process, specific movements in writing – notably, from strongly contextualized to more abstract meanings – are developed over time. In showcasing these findings, the chapter reveals how LCT is able to make this aspect of doctoral writing explicit and demonstrable to students and supervisors.

- Description: Mathematics is the foundation for the economic and technological development of any nation. It has been asserted that Mathematics is expected to help in accelerating social, economic and technological progress of any society. Performance of this subject is very important and there are different types of learners; such auditory, visual, and kinesthetic. Auditory learners appreciate listening to the teachers and sit down close to the teachers in class. Visual learners like to see things physically during teaching. They learn by materials like charts, graphs, and pictures. Kinesthetic learners learn by doing. Students can prefer one, two, or three learning styles; all these are subject to the availability of instructional materials. The Primary school level is very important in any educational system and any lack at this level would permeate to other levels of the educational system. Hence, this thesis examines the Learning Styles, Availability, and Utilization of Instructional Materials as Correlates of Grade 6 Learners’ Mathematics Performance in Buffalo City. The study adopted the positivist paradigm and employed the quantitative approach in investigating the phenomenon. The thesis made use of correlational research design as it attempted to find out the effects of learning styles and instructional materials on learners’ performance in Mathematics. Stratified sampling was used to select participants. Stratified sampling is a process of dividing the sample frame into strata to obtain relatively homogenous subgroups; this gave us 1225 Grade 6 learners selected across 35 schools in Buffalo City as the sample of the study. Three instruments which are Students’ Learning Styles Scale (SLSS), Availability and Utilization of Instructional Materials Inventory (AUIMI), and Mathematics Achievement Test (MAT) whose reliability co-efficient are; 0.87, 0.78 and 0.89 respectively. The data collected were analysed using descriptive and inferential statistics. The findings of the study revealed among others; students learning style (visual, auditory, and kinesthetic) have a significant relationship on Grade 6 learners Mathematics performance (B=-.113, t=-3.886, p<0.05). Students learning style (∆R2=.012, ∆F (1, 1223) = 5.047, p < 0.05) emerged as the best predictor of Grade 6 learners Mathematics performance in Buffalo City, while the availability and utilization of instructional materials (∆R2 = .000), ∆F (1,223) = .018, P > 0.05), and gender (∆R2 = .000, ∆F (1,1223) = .036, p>0.05) emerged as better predictors. The study further iv revealed that, Grade six learners with visual learning style ( = 13.242, SD = 5.565) had the best performance in Mathematics at Buffalo City, followed by learners with auditory learning style ( = 12.996, SD = 3.883), and learners with Kinaesthetic learning style ( = 11.525, SD =3.800). The study concluded that one of the most fundamental issues to consider in improving Mathematics performance is the understanding of the learners’ learning styles and effective use of appropriate instructional materials for teaching Mathematics.

- Description: We aimed to gain an in-depth understanding of the lived professional experiences of early career clinical and counselling psychologists in South Africa. Our informants were four early career psychologists (females = 2, males = 2; clinical = 2, counselling = 2; period in service = 1 to 7 years). They completed semi-structured interviews on their critical early career professional experiences, as well as the meanings they attributed to these experiences. Interpretative phenomenological analysis of the data yielded four super-ordinate themes: (i) training as a ‘rite of passage’; (ii) expectations for a professional future; (iii) entering the professional psychology workspace; and (iv) future career directions. Findings suggest employment opportunities in the healthcare system to influence the professional socialisation of early career psychologists in addition to their personal choices. Systemic factors appear to explain why South African psychologists would opt to practice privately, and why debates on the profession’s relevance, accessibility, and credibility may continue unabated.

- Description: Professional psychology in South Africa has experienced numerous transformations since its tainted historical affiliation with the apartheid regime. However, despite the profession’s attempts to respond to the burgeoning mental health needs of the country, psychologists in South Africa continue to be confronted by a number of challenges within the professional field. International research suggests that early career psychologists, in particular, experience further challenges in adjusting to new professional careers. Considering the dearth of research on this topic within local literature, the aim of this study was to gain an in-depth understanding of the lived professional experiences of recently qualified clinical and counselling psychologists in South Africa, following training. An interpretive phenomenological method was employed to investigate the fundamental early career professional experiences of participants, as well as the meanings participants attributed to these experiences. Four participants were recruited using purposive sampling. Data was collected through the use of semi-structured, one-on-one, Skype interviews, and the interview data were analysed using interpretative phenomenological analysis. The study revealed four super-ordinate themes, including: (i) Training as a ‘rite of passage’; (ii) Expectations for a professional future; (iii) Professional psychology: Entering the work space; and (iv) Future directions. The findings suggest that clinical and counselling psychologists’ experiences as recently qualified professionals in South Africa are both positive and negative, with the overall experience being positive. Emerging themes suggest that early career psychologists are faced by a number of personal and professional challenges on entering the work place. Furthermore, findings suggest that the early career experiences of recently qualified clinical and counselling psychologists in South Africa might not necessarily be due to personal choice, but rather due to greater systemic factors, such as limited available posts, maladministration, the devalued status of mental healthcare in comparison to other healthcare concerns in the country, an unresponsive marketplace and limited efforts by government to accommodate psychologists in different contexts

- Description: The life history of Risso's dolphins (Grampus griseus) remains poorly known and data from strandings can help provide important information. Data from 126 Risso's dolphins stranded or bycaught along the southeastern coastline of South Africa between 1958 and 2017 were analyzed in relation to their sex, age structure, and diet. Mean estimated length at birth was 146.9 cm, while maximum length was 325 cm for males and 313 cm for females; small sample sizes precluded detailed examination of sexual dimorphism. Age estimates for 33 individuals (14 males, 17 females, 2 unknown sex) indicated a maximum age of 13 years (males) and 17 years (females), respectively; the oldest animal was 19 years (unknown sex). Mean length and age at attainment of sexual maturity were estimated at 280 cm and 7.1 years in males and at 282 cm and 7.7 years in females. Stomach contents from 27 individuals showed that diets of immature and mature males and females overlapped and consisted predominantly of cephalopods. Reported strandings decreased between 2000 and 2017, possibly due to a lack of reporting associated with a ban on driving on beaches or related to the collapse of the local “chokka” squid (Loligo reynaudii) fishery in 2014–2015.

- Description: The margin of the Southern Africa continent harbours the history about the fragmentation and separation of Gondwana in its basins. The integration of onshore and offshore geology is of primordial importance to understand the complete geological history and evolution of the southern African border. The study focuses on the Gamtoos Basin, where the sediment deposits on the onshore portion are generally unfossiliferous and therefore difficult to correlate with the offshore portion of the basin. In an attempt to do this, several datasets were integrated such as old 2-D seismic reflection data and borehole wells. This data, acquired by SOEKER in the 1970s was purchased from the Petroleum Agency of South Africa (PASA). Some data reprocessing involved digitization and conversion of the old seismic data from TIF format to SEG-Y format. Conventional seismic stratigraphic method (Mitchum, JR, et al., 1977) was used to identify seismic discontinuities and remarkable stratigraphic surfaces and units based on reflection configurations and facies characteristics, and ages of these surfaces were provided by well data. Seismic interpretation was first done on printed seismogram papers, and then integrated into the ‘Kingdom Suite’ software to ensure coherency at all crossing lines. Isochron and Isopach maps (using QGIS, Mirone and tools such as GMT) were created. The first results, allow us to estimate for the first time a precise age calibration of onshore deposit. Furthermore, the delimitation in 5 second-order seismic sequences along the Gamtoos Basin suggest a link between different basin filling dynamics and kinematic phases related to the opening of the Indian and Atlantic Oceans along the southern Africa margins. The study shows that the Gamtoos Basin is an essential area linking the geological histories of both East and Western parts of the Southern Africa continent.

- Description: Trophic cascade theories such as the ‘behaviourally-mediated trophic cascade hypothesis’ (BMTCH), have mainstreamed as ecological tools for conserving biodiversity and restoring ecosystems. The BMTCH relies on indirect negative effects of large carnivores through suppression of mesocarnivore activity and habitat use. Importantly, effects of top carnivores on mesocarnivores varies over time and space, is dependent on the species involved, and local context. In South Africa, there are very few free-ranging carnivores, as populations are often restricted to enclosed reserves. While predator-proof fences reduce human-wildlife conflict, they also influence space use within communities. We used an enclosed reserve with a relatively full complement of carnivores to test the generality of the BMTCH in the African context. Using single-species, multi-season occupancy models we investigated the spatial dynamics of multiple carnivores. We also investigated spatial partitioning by vegetation type and temporal partitioning.

We also investigated spatial partitioning by vegetation type and temporal partitioning. Our results revealed both support for and against the BMTCH. Lions and spotted hyaenas negatively influenced the detection probability of black-backed jackals and African wildcats, while leopards had a positive effect on these two mesocarnivore species. Additionally, lions positively influenced the detection probability of side-striped jackals. Although space use of carnivores in relation to vegetation type showed minimal evidence of spatial partitioning, each carnivore had a unique combination of abiotic and biotic factors influencing their spatial dynamics, which could facilitate co-existence. Temporal partitioning may also be promoting co-existence as activity patterns of smaller carnivores overlapped the least with sympatric carnivores, particularly lions. Extensive activity overlap between large carnivores does not promote co-existence. We suggest that applying the BMTCH as a universal law across ecosystems is unsupported and may lead to inappropriate conservation and management actions, and prevent protection of ecosystems.

Temporal partitioning may also be promoting co-existence as activity patterns of smaller carnivores overlapped the least with sympatric carnivores, particularly lions. Extensive activity overlap between large carnivores does not promote co-existence. We suggest that applying the BMTCH as a universal law across ecosystems is unsupported and may lead to inappropriate conservation and management actions, and prevent protection of ecosystems.

- Description: In the geological record, fossil phosphatic stromatolites date back to the Great Oxidation Event in the Paleoproterozoic, but living phosphatic stromatolites have not been described previously. Here, we report on cyanobacterial stromatolites in a supratidal freshwater environment at Cape Recife, South African southern coast, precipitating Ca carbonate alternating with episodes of Ca phosphate deposition. In their structure and composition, the living stromatolites from Cape Recife closely resemble their fossilized analogues, showing phosphatic zonation, microbial casts, tunnel structures and phosphatic crusts of biogenic origin. The microbial communities appear to be also similar to those proposed to have formed fossil phosphatic stromatolites. Phosphatic domains in the material from Cape Recife are spatially and texturally associated with carbonate precipitates, but form distinct entities separated by sharp boundaries. Electron Probe Micro-Analysis shows that Ca/P ratios and the overall chemical compositions of phosphatic precipitates are in the range of octacalcium phosphate, amorphous tricalcium phosphate and apatite. The coincidence in time of the emergence of phosphatic stromatolites in the fossil record with a major episode of atmospheric oxidation led to the assumption that at times of increased oxygen release the underlying increased biological production may have been linked to elevated phosphorus availability. The stromatolites at Cape Recife, however, form in an environment where ambient phosphorus concentrations do not exceed 0.28μM, one to two orders of magnitude below the previously predicted minimum thresh-old of >5 μM for biogenic phosphate precipitation in paleo-systems. Accordingly, we contest the previously proposed suitability of phosphatic stromatolites as a proxy for high ambient phosphate concentrations in supratidal to shallow ocean settings in earth history.

- Description: This thesis explores the use of a postmodernist aesth etic in Alain Mabanckou’s oeuvre, namely Blue White Red, African Psycho, Broken Glass, Memoirs of a Porcupine, Black Bazaar, Tomorrow I’ll Be Twenty, The Lights of Pointe-Noire, and Black Moses. In particular, I show how and why this Afrodiasporic author localises strategies associated with Western postmodernist writing in an African postcolonial context. My central argument is that if postmodernism is a critique of modernity in the West, then it must also be a respon se to enforced modernity in the African postcolonial context. In mounting this argument, I conduct a close reading of Mabanckou’s novels from within the theoretical frameworks of postmodernism and postcolonialism. I demonstrate that Mabanckou’s writing adu mbrates the possibility of a postcolonial postmodernism. Since he is a French-Congolese citizen, his writing evinces aesthetic glocalisation. That is, as a postcolonial writer, he conceives of, and inflects, postmodernism differently from a Western writer, for his experiences of and responses to modernity differ from the latter’s. Far from replicating a politics of disillusionment and despair that informs, even characterises, Western postmodernist fiction, Mabanckou invests hi s African postcolonial writing with a politics of decolonis ation which problematises the effects of enforced modernity. Postmodernism, in other words, accords Mabanckou an ambivalent position from which he interrogates both Western modernity and its African version. Significantly, in this regard, Mabanckou’s writing presents both an extension of and a departure from the pioneering influence of the first generation of African writers such as Chinua Achebe, Ngugi wa Thiong’o, and Wole Soyinka.
