- Description: The African wildcat (Felis lybica cafra) is the most common and widely distributed of all wildcats. The southern Kalahari in South Africa offers favourable conditions for African wildcats and supports high wildcat densities on protected and unprotected land. African wildcats have been reported as livestock predators on South African farms, however wildcat-livestock predation is usually reported as infrequent and to have a low financial impact on the farmer. The aim of this study was, firstly, to determine what natural prey species were available for African wildcats on unprotected land and, secondly, to determine the extent of human-wildcat conflict on unprotected land in the southern Kalahari. The frequency of occurrence of potential African wildcat prey was determined through small mammal trapping, camera trap surveys and direct observations. The results indicated that a variety of the African wildcat’s natural prey species occurred on unprotected land and that the dune and adjacent ‘street' habitats most likely supported the majority of small mammals which are preferred prey for African wildcats. The African wildcat’s human-predator conflict status was determined through interview questionnaires (n = 22) with participants who owned or managed farms in the southern Kalahari. African wildcats were perceived to occur on 100% of farms, to be common in the region, to be the top livestock predator on 68% of farms and to be responsible for 46% (n = 1542 newborn lambs) of all livestock deaths in 2020. African wildcats were, however, not viewed in the same negative light as black-backed jackals (Canis mesomelas) and caracals (Caracal caracal), who received more negativity from participants and who had the highest persecution rates in my study area. This result could potentially be explained by a combination of generationally taught hatred towards certain species and due to the perceived livestock loss (e.g. livestock size and species) caused by each predator species. It is important to research and monitor wildcats outside protected areas to obtain a deeper knowledge of wildcat behaviour, abundance, population dynamics and other aspects of their ecology. By doing this, specific conservation and management questions can be addressed and through the knowledge of the natural history of a species, conservation failures can be avoided. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021

- Description: Wiener index is defined as the sum of the distances between all unordered pairs of vertices in a graph. The study of the Wiener index is motivated by its application in chemistry. This thesis focuses on finding extremal bicyclic graphs relative to Wiener index under various conditions such as fixed circumference (length of the longest cycle) or fixed size of the core (maximal subgraph with no degree less than 2). A segment of a graph G is either a path whose end vertices have degree 1 or at least 3 in G and all the internal vertices have degree 2 in G, or a cycle where all the vertices have degree 2 in G except possibly one. The lengths of all the segments of G form it segment sequence. We also discuss extremal graphs with given segment sequence. , Thesis (MSc) -- Faculty of Science, Mathematics, 2021

- Description: Absenteeism from school among girls due to a lack of menstrual health management (MHM) products has increasingly attracted attention from researchers and activists in recent years. Having highlighted the challenges caused by a lack of MHM products, the focus has been on the available facilities at schools to ensure MHM. Many schools in South Africa lack water, sanitation and hygiene (WASH) to ensure hygiene standards for the removal of bodily excre-ment, which further causes distress to girls needing MHM while at school. To investigate fur-ther the MHM challenges girls face, apart from access to products and WASH, this qualita-tive study purposively selected an all-girls’ school with access to good sanitation facilities. This research uses Foucauldian Discourse Analysis and Feminist Theory to explore the forms of discipline and control that girls experience at school to contain their bodily functioning and fluids, and the forms of resistance and support that girls encounter with MHM at school. I will argue that the ambivalent meanings girls acquire about menstruation at home and in soci-ety persist at school despite their own views that menstruation is normal. While MHM prod-ucts and WASH facilities need to be freely available, the problematic social response to men-struation is what needs to be addressed in order to emancipate women from the social patriar-chal power that informs their understanding that menstruation is shameful. MHM cannot only encompass products and facilities but needs to encompass a change in societal views of sex-ual and reproductive health. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021
