- Description: Invasive alien plants (IAPs) are introduced species that constitute a self-sustaining population, consistently producing offspring in large numbers and at considerable distances from the parent plants with the potential to spread over a large area. Species invasions are one of the main conservation threats today and have caused modification of ecosystems, particularly in coastal areas. Therefore, Port St Johns Local Municipality (PSJ LM) was an appropriate study site to evaluate the local awareness and perceptions of IAPs. The study investigated the local community’s perceptions of invasive alien plants' uses and ecological impacts. Information about the local awareness and perceptions of invasive alien plant species in PSJ LM was gathered through semi-structured interviews, observation and guided field walks with 120 participants between February and April 2021. The participants included 30 people working on the alien plant eradication project in PSJ LM (Wards 1, 2 and 3) and 90 randomly selected community members. The data collected were entered in Microsoft Excel 2016 programme and analyzed for descriptive statistical patterns using Statistical Package for Social Studies (SPSS) version 22.0. Biological invasion by IAPs was ubiquitously perceived, with participants working on invasive alien plant eradication project in the area exhibiting more scientifically based knowledge on IAPs than ordinary community members. Invasive alien plants in the area appear to have adverse environmental and socio-economic impacts, as the participants are not benefiting from these plant species. Similarly, costs of eradicating these species were also acknowledged. The ability of local community members to identify IAPs is vital in effective management of the spread of these species. A total of seven invasive IAPs were recorded. Evaluating the perceptions of local people towards IAPs provides valuable insights for development planning and future management programmes focusing on biological invasions. The study will provide a basis for an enabling policy and institutional environment that provides a coherent framework for the sustainable management of IAPs in the Eastern Cape Province. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2021

- Description: The benefits of participating in sport have been well documented and great emphasis has been placed on the role that it plays in the development of character and social skills, apart from physical and psychological benefits. Sport represents an optimal means of enabling children and adolescents to meet their daily requirements for physical activity to maintain health. Conversely, despite all of the widely acknowledged benefits, participation in sport among children and adolescents continues to decline throughout the world. Although a great deal of research has been conducted to identify barriers to participation in sport, most of it has concerned poor, rural, disadvantaged, or other marginalised groups. As a consequence, a large proportion of the research has attributed low rates of participation in sport to practical barriers, which usually take the forms of either logistical problems or a lack of resources. The aim of this study was to identify the barriers to participation in sport among adolescents in an affluent, urban setting, at an international school in Cape Town, South Africa. The Barriers to Sport Participation Questionnaire was used to identify the social, personal, and practical barriers that affected 107 adolescents who were enrolled in the school. The data was analysed by means of the SPSS (IBM, Version 27) software package and seven significant barriers were identified. Fear of academic failure, environmental constraints, and lack of interest were identified as the primary barriers, thereby emphasising the significant influence of personal barriers, rather than practical ones. It was also found that the influence of particular barriers was greater on females than their male counterparts and that the respondents who either did not participate in sport themselves or were from households in which other members did not do so were more adversely affected by some barriers than the others. Significant correlations were found between some grades and certain barriers, the most notable being those between respondents in Grades 7, 9, and 10 and the fear of academic failure barrier. In light of these findings, it could be concluded that the global decline in participation in sport among the youth is a complex problem and that particular barriers, which might not have been identified in previous research, could be particularly influential in affluent environments. As it is evident that as barriers can be specific to particular groups and settings, the optimal means of overcoming them is unlikely to be found through the adoption of a one-size-fitsall approach. Instead, further research and customised interventions are required. , Thesis (HMS) -- Faculty of Health Sciences, 2021

- Description: The exposure of livestock to antimicrobials for treatment, prophylaxis, or development advancement can select for antimicrobial resistant organisms that can be transmitted to humans. Salmonella as a significant zoonotic microorganism can go about as a likely supply of antimicrobial resistant determinants. Salmonella is a zoonotic pathogen that causes food and waterborne infections. It affects wild and domestic animals, and humans, by causing a number of infections including Salmonellosis. Salmonella species infect humans through the consumption of contaminated meat, like beef, chicken, pork etc. This study aimed to determine the molecular characterization and antimicrobial resistance profile of Salmonella species isolated from effluent discharged from the Fort Hare Dairy Farm in Raymond Mhlaba Local Municipality. Polymerase chain reaction (PCR) was used for the molecular confirmation of the presumptive Salmonella isolates targeting both ompC gene and typh gene. Standard disc diffusion method was used for the antimicrobial susceptibility testing (AST) as recommended by the Clinical and Laboratory Standards Institute. The confirmed Salmonella isolates were tested against 12 test antimicrobial agents and were screened for antimicrobial resistance genes (ARGs) including blaTEM and amp for beta-lactams, and tetC for tetracycline. The research showed that the effluent discharge from this farm is contaminated with Salmonella. Presumptive Salmonella densities were ranging between 1,7 ×102 to 6,1×102 CFU/100ml, out of 83 presumptive isolates recovered, 61 were molecularly confirmed Salmonella typhimurium. The most prevalent Salmonella species found in this study was Salmonella typhimurium, which was more abundant in the final effluent discharges than in the water samples. This may be due to the contamination from farm animal faeces. The susceptibility against 12 different antibiotics by the recovered Salmonella typhimurium were examined, and Salmonella typhimurium isolates was notably resistant to azithromycin, ampicillin, amoxiclav, but less resistance were seen on doripenem , meropenem and ciprofloxacin but none of the isolates were resistant to norfloxacin. Antibiotic results obtained from this research suggest that Quinolones (Norfloxicin, Ciprofloxacin and Nalidixic acid), and Carbapenems (Meropenem and Doripenem.) were the most effective antibiotics against Salmonella. Forty-eight percent of isolates were found to be resistant to more than 3 antibiotics from different families thus considering them to be multidrug resistant. Resistant determinants ampC, blaTEM and tetC were detected on resistant isolates. Misuse and overuse of antibiotics on animal producing farms put human lives at risk as it promotes the emergency of multidrug resistant bacteria. Findings of this study revealed that animal producing farm pose a threat to the community as they harbour and promote the emergence of multidrug resistant Salmonella typhimurium. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: This study examined water struggles and rural people’s experiences of waiting in South Africa’s Eastern Cape Province. Primarily, it investigated how such struggles connect to people’s experiences of waiting for water services. In essence, the study demonstrates how experiences of waiting are profoundly shaped by subjective meanings that the rural people attach to water at a local level. Thus, the study connects rural water politics to contested meanings over natural resources in South Africa’s communal areas. The empirical analysis in this study goes beyond the largely urban focus in the focus in the politics of waiting – mainly in the informal settlements, slums and other urban peripheries. The study presents some of the less known struggles of rural dwellers, particularly their experiences of waiting for water service provision from the state. South Africa’s Constitution promotes the right to clean water. Despite all the progress made by the democratic government, it is still evident that people in deep rural areas of South Africa are in a very precarious situation when it comes to accessing clean water. The study utilised Auyero (2011) concept of the politics of waiting to examine the poor people’s experiences of waiting for water. The study adopted a case study of Lower Didimana village. The researcher conducted a range of qualitative research techniques – the key informant interviews, focus group discussions, observations and semi-structured interviews. The study found that rural residents of South Africa continue to wait for long periods for water service provision in the current democratic era. Moreover, they are still faced with severe challenges of accessing water; as a result, they are left with no better option but to use traditional ways of retrieving water. It also found that there are strong cultural and spiritual claims that rural dwellers attach to water. To them water is not just only a physiological need which could be addressed through efficient state service – the provision of sufficient tap water. Water is deeply connected in human existence. Just like land, water is a cultural as well as spiritual resource. As such, rural experiences of waiting are not limited to state agency and how the poor experience the state, but are also influences by local struggles over meanings of water. Finally, the study reveals the limitation in state policy on water provision, which is locked in a purely engineering use based paradigm, which mainly strives to address (technically) scarcity of drinking water. However, the findings of this study demonstrates that drinking is just one function of water. Although villagers try to mobilise to engage the state while waiting for water service they articulate other claims that connect to diverse water meanings. Such meanings are barely captured in contemporary literature on rural politics of water. As such, although water is increasing becoming scarce in rural South Africa and the state intervention is increasingly demanded, villagers’ experiences of waiting in Lower Didimana remain strongly connected to what water means to locals. , Thesis (MSoc Sci) (Rural Development) -- University of Fort Hare, 2021
