- Description: This study focused on the use of data from four wells (Ga-M1, Ga-S1, Ga-Z1, and Gb-J1) comprises of the Late Jurassic to Early Cretaceous shallow marine clastic sandstones consisting of wildcat wells located in Block 11 of the Pletmos Basin, a sub-basin of the Southern Outeniqua Basin, south offshore South Africa. This research evaluates the hydrocarbon potential in the Pletmos Basin by integrating core and well log data to characterize the source and reservoir rock potential. The methods implemented consist of a mineralogical and petrological analysis of about 300 thin section slides from four wells were studied. Stratigraphic profile computation from core logging, geochemistry analysis focusing on total organic carbon (TOC), geophysical wireline logs, conventional core analysis, geological well reports, and petrophysical analysis (water saturation, porosity, permeability, and volume of clay) were done using Interactive Petrophysics software. The different datasets were used to delineate how the mineralogy, total organic carbon content, poro-perm properties, fluid saturation, and volume of clay impact the hydrocarbon production potential. The evaluated sandstones have depths ranging from 2523.9 m to 3397.2 m with varying thickness depending on the position of the well. The results indicate that the study area consists of shallow marine clastic sandstones with sparse siltstones and mudstone that are fine-grained to silty in texture. The sedimentary sequence is characterized by moderate to intense bioturbation. Depositional environment was in a reducing condition indicated by plenty of glauconites. The tight fine-grained sandstones have low porosity values ranging from 4.5% to 13.8% in the selected intervals. The low porosity values may have been caused by the quartz cement that is observed from the thin sections. Low permeability values ranging from 0 mD to 0.16 mD are present throughout the studied wells caused by calcite cement and clay matrix. Source rock in the studied wells have inferior TOC values ranging from 0.31 wt% to 0.51 wt%. The van Krevelen indicates that the analysed samples have very low hydrogen index (HI) values and are consistent with Type III Kerogen (gas prone). A total of six reservoirs were identified. For well Ga-M1, one reservoir interval (2988.2 m – 30281 m) was selected and is located at BCII formation and was classified as a nonproducing reservoir due to its high water saturation content of 94.2%, even though it has an average porosity of 10.6%. Two reservoirs were selected for well Ga-S1, reservoir one (3026.3 m – 3107.7 m) is located within the 13AT1 formation and was classified as a producing reservoir with an average porosity of 11.9%, water saturation of 38.3%, and volume of clay of 29.5%. Reservoir 2 (3380.7 m – 3397.2 m) and the reservoirs (2970.20 m – 2993.0 m and 3006.80 m – 3049.50 m) from well Ga-Z1 located between the 9AT1 – BCVI formations were classified as non-reservoirs. One selected reservoir from well Gb-J1 had promising gas shows with an average porosity of 19%, water saturation value of 34.8%, and volume of shale of 33.1%. However, well Ga-S1 has a large interval with hydrocarbon potential compared to the well Gb-J1. Results indicate that the absence of hydrocarbon accumulation may result from non-effective seals due to the silty texture of the reservoir sandstones. Also, the presence of calcareous cement, clay minerals, and the argillaceous matrix reduce the porosity and permeability characteristics. To better understand the hydrocarbon potential of the Pletmos Basin, 3D seismic data is recommended to perform seismic well tie analysis for correlation between well log and seismic data to understand the basin‟s potential better. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Deviant behaviour within the school setting poses a threat to the physical and social survival of individuals. Therefore, this study explored the dynamics of deviant behaviour among school learners in a selected boy’s high school in the Eastern Cape Province in South Africa. The study had the central aim of achieving the following specific objectives: (i) identify factors contributing to deviant behaviour among school learners, (ii) ascertain consequences of deviant behaviour among school learners, and (iii) establish preventative measures that should be employed to address deviant behaviour among school learners in a selected boy’s high school in the Eastern Cape Province in South Africa. The study utilised a qualitative research approach and a qualitative research paradigm in the form of case study research design. In terms of data collection, the study applied an in-depth one-on-one interviews and focus group discussions. Furthermore, the study employed non-probability sampling, specifically snowball sampling, and sampled twenty (20) participants. These comprised ten (10) learners, three (3) Life Orientation (LO) teachers and seven (7) key informants (School Governing Body (SGB) members and the school principal). In addition, the study employed a qualitative data analysis approach, with data being analysed thematically. The study established that there is no single cause of deviant behaviour among school learners but a series of distinct factors contributing towards deviant behaviour in various ways, such as use of drugs, low self-esteem, poor upbringing, and poor academic performance. Other factors included negative peer group influence, social media, and lack of self-discipline as well as lack of moral values and negative self-concept. The study concludes that through implementation of awareness campaigns, deviance policy, educational programmes, sport and recreational activities, safety and security, and social and behavioural change programmes, deviant behaviour can be addressed at school. Furthermore, it can be concluded that good behaviour among learners are central to effective teaching and learning at school; therefore, this should be inculcated in the learners. In light of the above findings, the Department of Education (DoE), policy makers, and school administrators should ensure that schools are provided with adequate facilities for teaching and learning, sports and recreational activities as well as information communication technologies and internet connectivity. School principals, members of School Governing Bodies (SGBs), teachers and parents should reduce deviant behaviour though increased supervision. , Thesis (MSoc) -- Faculty of Social Science and Humanities, 2021

- Description: Caregivers of children with Cerebral Palsy (CP) may experience some challenges and need support in caring for these children who present with a group of neurological disorders. Cerebral Palsy has been defined as a non-progressive condition of the brain, which results from interference during its development and affects body movement, muscle coordination, including motor and cognitive impairment. The objectives of the study were; to explore, describe, and interpret the experiences of caregivers of children with CP, to interpret the meaning attached to the experiences and interpret different support for caregivers of children with CP in Buffalo City Metropolitan Municipality, South. The University of Fort Hare Ethics Committee granted ethical approval. Informed consent was obtained from the participants before data collection. Ethical principles to be followed when conducting a research study has also been discussed with participants and ensured. An Interpretive Phenomenological Analysis (IPA) was chosen for the study. Four participants were chosen purposively in this study because IPA studies use a detailed account of individual experience. The data collection method used for this study is semi-structured interviews, which were done in the participant’s comfortable environment, and lasted between 40 to 60 minutes, using an interview guide. Data analysis has been done using the 7 steps noted in IPA. The main findings of the study are lived experiences of caregivers caring for children with CP. Participants experienced financial, physical, and psychological challenges in caring for children with CP. Caregivers also received communal support from different stakeholders. Support from family, their employers, other caregivers and the government through the multi-disciplinary team and the provision of social grants. Trustworthiness was ensured by observing the principles of transferability, credibility, confirmability and dependability. , Thesis (MNurs) -- Faculty of Health Sciences, 2021

- Description: Movements of the adult spotted grunter (Pomadasys commersonnii), an overexploited estuary-dependant fishery species, were investigated in relation to its reproduction behaviour and selected environmental influences. The South African P. commersonnii population is known to spawn at sea along the KwaZulu-Natal (KZN) coastline, whereas there no published records on spawning in the Eastern and Western Cape Provinces exist. However, due to the occurrence of ripe running fish that were reported in the Breede Estuary (Western Cape - WC), an investigation into its reproductive behaviour was necessary, as was gaining a greater understanding of its movements between the estuary, the sea, and other connected habitats. Seven adult P. commersonnii (610 – 690 mm fork length, FL) were captured and implanted with long-life acoustic transmitters and their movements were logged on a linear array of 16 acoustic receivers in the Breede Estuary (WC) and six acoustic receivers in the adjacent marine environment. Movements of the tagged fish to other marine and estuary habitats were also determined using data collected by the Acoustic Tracking Array Platform (ATAP) which is an extended network of acoustic receivers along the South African coastline with receivers at sea and in selected estuaries. Furthermore, adult P. commersonnii tagged in the Goukou (n = 6) (WC) and Sundays (n = 8) (Eastern Cape - EC) estuaries, approximately 50 km and 470 km away, respectively, were also monitored to facilitate an improved understanding of inter-habitat connectivity. Fish tagged in Sundays and Goukou estuaries were monitored by the Acoustic Telemetry Array Platform (ATAP). Each individual fish tagged in the Breede Estuary was monitored between 356 and 1166 days and selected environmental parameters, including water temperature, river flow rate and rainfall, were measured during the study period (November 2016 – March 2020) to assess their influence on the movements of the tagged fish. Furthermore, to determine time of spawning and duration, gonads of 112 adult fish (383 – 700 mm FL) were opportunistically collected from recreational anglers in the Breede Estuary to determine the gonadal maturation cycles by using a combination of Gonado-somatic index (GSI) and histology. The tagged adult P. commersonnii spent significantly more time in the estuary (83.5 percent) than the marine (16.5 percent) environment, with all of the tagged P. commersonnii making sea trips of varying frequency and duration. While in the estuary, fish showed a strong preference for the lower reaches of the estuary compared to the middle and upper reaches. Area use varied seasonally, with the mouth area being heavily utilized during winter, then followed by summer. Sea trips in all three tagging estuaries also fluctuated seasonally, with more frequent movements during summer which lasted for longer periods. This coincided with the peak of the spawning period inferred from the gonad developmental cycle of fish captured in the Breede Estuary. Results from a generalized linear mixed model showed that the presence of Breede tagged P. commersonnii in the sea, where the species is known to spawn, was significantly influenced by water temperatures in the estuary and river flow rate with fish more likely to occur at sea during warmer months (summer) and periods of high river flow (winter). Furthermore, circular analysis showed that season (month) had a significant influence on the departure from and arrival in the Breede Estuary, with most departures and arrivals occurring during January. Moreover, P. commersonnii tagged in the Sundays Estuary also showed similar results where both departures and arrivals were influenced by season, mostly taking place in December and January, respectively. The increased frequency of sea trips by adult P. commersonnii in summer suggests regional spawning occurring in the WC. Based on the similar movement behaviour displayed by tagged fish in the Sundays Estuary, it is possible that spawning also occurs in the EC. Most of the P. commersonnii tagged in all the three estuaries never left their tagging estuaries (57 percent Breede, 66 percent Goukou, 38 percent Sundays), only making short sea trips, while others displayed use of multiple habitats. On average, the tagged P. commersonnii that left their tagging estuaries travelled a maximum distance of 377 km (Breede), 63 km (Goukou) and 300 km (Sundays). Tagged fish were more likely to visit nearby estuaries and offshore marine habitats (< 130 km) compared to distant ones (> 130 km). These results suggest that there are high levels of localised connectivity between P. commersonnii populations in different habitats although connectivity between distant habitats appears to be rare. Connectivity will likely occur on habitats located close to the boundaries of the WC, EC and KZN. The findings from this long-term monitoring study have shown that adult P. commersonnii rely heavily on the estuarine environment, undertaking short sea trips, thus demonstrating the importance of estuaries to the adult population. Due to various threats faced by estuaries such as habitat degradation and overexploitation, management of these systems is paramount to conserve such fishery resources. Due to the resident behaviour of the P. commersonnii within estuaries, Marine Protected Areas (MPAs) and area closures, in conjunction with Estuarine Protected Areas (EPAs) will be significant in the recovery and management of P. commersonnii populations. Since P. commersonnii appears to reach peak spawning activity during summer when fishing pressure is usually highest, improved enforcement during this period is necessary to conserve the spawning stock. As connectivity is an important aspect in the life of the P. commersonnii, ensuring such connectivity is maintained by protecting all these habitats is important. , Thesis (MSc) (Zoology) -- University of Fort Hare, 2021

- Description: BACKGROUND: Generally, many people in South Africa have difficulty accessing quality health services due to poor public service. Over 42 million citizens do not have health insurance and are growing sicker as they age. Health facilities, such as public health centers, are their only recourse. Health authorities in South Africa fail to monitor patient care effectively, as evidenced by their uninspiring record on patient experience. Anecdotes of poor patient experiences are extensive with the health ombudsman. The Office of Health Standards Compliance (OHSC) reports horrifying stories of patients sleeping on hospital floors due to the shortage of beds, patients unable to receive critical surgical treatment due to shortage of doctors, medical supplies and equipment failure or lack thereof. A few union protests have highlighted the poor quality of public healthcare. But it is not uncommon for South Africans to voice their displeasure over poor public healthcare. Health services are individualised and there is no specific interest group or community that is affected by this overall unpleasant experience. Indications of the growing public campaign against the deteriorating healthcare system may be as simple as the increasing number of medical legal claims. This study focuses on the implementation of national core standards with specific reference to clinical leadership. This study focuses on the implementation of national core standards with specific reference to clinical leadership. RESEARCH AIM: This research seeks to explore the effectiveness of the implementation of NCSs with specific reference to Clinical Leadership in Frere Hospital. It also wants to assess if the Frere hospital upholds the national core standards METHOD: qualitative research design was used in this study. Semi-structured, individual interviews were conducted. CONCLUSION: The researcher concluded that it is quite evident that the public health sector is complex and that environmental influence affect the ECDOH Functions within the health system. There is a relationship between clinical leadership and service delivery; now, to improve service delivery within the Frere hospital, strong leadership is needed to drive the change towards implementing the NCS. Ultimately, Frere hospital does not uphold the NCSs, and the staff needs to be educated on what is and how it can improve the hospital’s service delivery. RECOMMENDATIONS: Effective public leadership development, high performing and accountable leadership behavioural measurement at the most senior level at the Frere hospital is very empirical in driving effective delivery of services to patients. Effective Performance management, visible leadership role at all management levels. Performance appraisal system needs to be engineered to focus on performance and results. Recognition and Implementation of clinical leadership. Establish a culture and implementation of good governance principles in health institutions. Establish an institution based OHSC office that is visible and implement NCS through Batho Pele Principles. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

Health authorities in South Africa fail to monitor patient care effectively, as evidenced by their uninspiring record on patient experience. Anecdotes of poor patient experiences are extensive with the health ombudsman. The Office of Health Standards Compliance (OHSC) reports horrifying stories of patients sleeping on hospital floors due to the shortage of beds, patients unable to receive critical surgical treatment due to shortage of doctors, medical supplies and equipment failure or lack thereof. A few union protests have highlighted the poor quality of public healthcare. But it is not uncommon for South Africans to voice their displeasure over poor public healthcare. Health services are individualised and there is no specific interest group or community that is affected by this overall unpleasant experience. Indications of the growing public campaign against the deteriorating healthcare system may be as simple as the increasing number of medical legal claims. This study focuses on the implementation of national core standards with specific reference to clinical leadership. This study focuses on the implementation of national core standards with specific reference to clinical leadership. RESEARCH AIM: This research seeks to explore the effectiveness of the implementation of NCSs with specific reference to Clinical Leadership in Frere Hospital. It also wants to assess if the Frere hospital upholds the national core standards METHOD: qualitative research design was used in this study. Semi-structured, individual interviews were conducted. CONCLUSION: The researcher concluded that it is quite evident that the public health sector is complex and that environmental influence affect the ECDOH Functions within the health system. There is a relationship between clinical leadership and service delivery; now, to improve service delivery within the Frere hospital, strong leadership is needed to drive the change towards implementing the NCS. Ultimately, Frere hospital does not uphold the NCSs, and the staff needs to be educated on what is and how it can improve the hospital’s service delivery. RECOMMENDATIONS: Effective public leadership development, high performing and accountable leadership behavioural measurement at the most senior level at the Frere hospital is very empirical in driving effective delivery of services to patients. Effective Performance management, visible leadership role at all management levels. Performance appraisal system needs to be engineered to focus on performance and results. Recognition and Implementation of clinical leadership. Establish a culture and implementation of good governance principles in health institutions. Establish an institution based OHSC office that is visible and implement NCS through Batho Pele Principles. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

- Description: Gender-based violence is a global epidemic. Masculinities-focused interventions have a positive influence on behaviour and contribute toward positive attitudes and gender equality (Das et al., 2012). These interventions have a positive influence on factors associated with gender-based violence. However, some studies found that this influence is behavioural and does not influence patriarchal beliefs (Jewkes et al., 2010; Roy & Das, 2014). Highlighting that intervention on gender-based violence requires redress. This research sought to establish what has been published in academic literature on the influence of masculinities on gender-based violence. The research was addressed through the social constructionist paradigm; it used a mixed methods approach to research. A content-analysis was applied to 100 published academic articles that were sampled from the University of Fort Hare’s online library database using purposive sampling. The research method and design is appropriately suited to the theoretical framework – social constructionism. Qualitative Data Analysis (QDA) software was used to code the quantitative and qualitative data through deductive and inductive means. The quantitative results were interpreted using descriptive statistics. The qualitative findings were analysed using thematic analysis (Braun and Clarke, 2006). The research in this sample is mostly qualitative, majority of the research within the sample was published between 2007 and 2018, and male participants are primarily focused on within research on this topic. Majority of the research within the sample was conducted using North American Participants. The findings support previous literature. They indicated that masculine norms, compensatory masculinity, and victimization of gender non-conforming individuals are the most prominent themes within the sample. The results indicated various gaps within the research. There is an indication that different dimensions of masculinity are associated with different forms of gender-based violence. It is recommended that future research focus on the different dimensions of masculinity and their association with various forms of genderbased violence in order to appropriately inform preventative strategies and intervention. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2021

- Description: This study investigated information communication technology for personal information management by the University of Fort Hare (UFH) students in the Faculty of Social Science and Humanities (FSSH). The objectives were to: find out which information communication technology applications and tools the students often use to acquire personal information; determine at what stage the students often experience a high influx of personal information and how to cope with the technology, and establish the challenges the students encounter when using information communication technology to manage personal information. The aim was to assess information communication technology for personal information management by UFH students in the FSSH. A sample of sixty respondents was randomly selected to represent a large population hoping that the results could be generalized to all FSSH students and make predictions. A quantitative research approach was chosen, utilizing the survey design and the Theory of Planned Behavior because of attitudes, behavioral control, and subjective norm. The findings reveal that 55percent of the students prefer to use portable devices, laptops to be specific to access and store information. Even though there are many search engines, 93percent of the students often use Google to search and access academic purposes on the internet. Their primary reason is that it is easy to access, download, and store information from Google. It was also established that 26percent of the students face challenges such as slow internet or damaged computers, unavailability of Wi-Fi, and crowded computer labs. This hindered their learning process. As a result, out of desperation, racing against time to submit assignments, students end up committing plagiarism. Moreover, the study's findings showed that 50percent of the students encounter information overload before they write their exams because, at this point, they are working towards collecting as much information as possible to be prepared for the exams. Furthermore, the study affirmed that 57percent of the students agree that possessing computer skills helps students in their academic journey and confirmed that students from previously disadvantaged backgrounds lack of computer skills negatively affect their academic performance. They need a quantum leap to acquire computer skills imperative for their information access, engagement, consumption, and knowledge production. , Thesis (MLIS) -- Faculty of Humanities, Social Science and Humanities, 2021
