  • Description: This study offers a comprehensive examination of the Zimbabwean war of independence depicting the mobilisation of forces of liberation against an intransigent colonial Rhodesian settler state during a critical decade of the 1970s. Its introductory outline presents a broad historical context to the decolonisation processes in Africa. It also introduces the two liberation movements that drove the war of independence, and these revolved around the Zimbabwe African People’s Union (ZAPU) and the Zimbabwe African National Union (ZANU). The empirical chapters of the thesis narrow the focus to the main research subject, that explain the ZANU’s guerrilla warfare and how that was launched under the military wing of the Zimbabwe African National Liberation Army (ZANLA). The study looks, particularly on how and why that formation assembled groundswell support and generated pervasive intelligence to operate relentlessly against the Rhodesian colonial government resulting in a compromised independence in 1980. In addition to a wide-ranging survey of literature that deals with the Zimbabwean war of independence, the production of this thesis is thoroughly grounded on empirical methods that hinge on archival research and oral testimonies. The study breaks new ground in outlining the various facets and different phases of the Zimbabwean liberation war. It reveals that the liberation fighters were not merely provided with arms and deployed to fight the Rhodesian army. Rather they underwent a methodical process, which comprised recruitment, extensive training and fundamental political education. This re-represents an alternative narrative or even eccentric paradigm to that persistently presented within the conventional Zimbabwean liberation war historiography. The thesis breaks further new ground in discussing the complex nature of how intelligence gathering and propaganda uses were also centrally linked to the cooperation of or assistance from the various segments of the colonial African society. Its empirical chapters outline the various actions undertaken by the various groups and individuals, the language they adopted in expressing themselves and the convivial connections between them and the guerrilla fighters in the countryside as the war front expanded within the home boundaries. Chapters also explore in greater detail how the liberation movement bred the complex relation and contestation between the political formation of ZANU and its military wing, ZANLA. The uneven power relations between these two formations somehow dictated the course and the outcome of the liberation war. As a result a constitutional settlement or military victory became the two options by which the Rhodesian question could be resolved in the later 1970s. As it turned out, attempts to seek a constitutional solution became a feature of diplomatic dimensions of the postcolonial Rhodesian political landscape. The study concludes with the latter point. , Thesis (PHD) -- Faculty of Social Sciences and Humanities, 2011

  • Description: The development of wind energy is increasing globally and is often considered more environmentally friendly when compared to fossil fuel technologies. However, one of the ecological drawbacks of wind energy are the collisions of wildlife with turbine blades. In addition, the resulting anthropogenic landscape transformation can negatively impact populations. The Cape Vulture (Gyps coprotheres), a large endangered southern African endemic species, thus may be at risk from turbine development. The species has decreased dramatically in the past 50 years and understanding how additional mortalities from wind turbine impacts affect the population is needed to ensure effective conservation efforts. This study aimed to determine the population response to this emerging threat. This study first reviewed the species-, site- and wind farm- specific traits that make Gyps species vulnerable to collision with wind energy infrastructure. It examined the monitoring practices employed during the pre- and post-construction phase and mitigation measures in South Africa and compared it with international standards. Furthermore, wind energy development may disrupt landscape connectivity and understanding which, and how habitat patches are used is needed. Using network theory combined with telemetry data from tagged individuals across three age classes, habitat patch use was identified. Further, environmental variables associated with identified habitat patches were identified. Additionally, considering the wind energy industry is expanding in South Africa, exploring how the Cape Vulture population will respond to this novel and emerging threat may aid future conservation management plans. Therefore, using a population viability analysis approach, the study explored how present and future wind turbine mortality scenarios impact the Cape Vulture population and how the population will respond to increased wind turbine development. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 65 , Apogon niger Doderlein, 1883 of the western Pacific and Apogon nigripinnis Cuvier, 1828 (Apogon thurstoni Day, Amia nigripes Ogilby, and Amia atripes Ogilby are synonyms) of the eastern Indian Ocean and Australia are regarded as valid species distinct from Apogon pharaonis Bellotti, 1874 of the western Indian Ocean (Apogon suezii Sauvage, Amia ocellata Von Bonde, and Apogon duops Barnard are synonyms). Apogon nigripinnis differs from A. niger in having a large ocellus between the lateral line and the pectoral fin. A lectotype for A. niger is designated. A. pharaonis differs from both these species in having shorter pelvic fins, 16-21 instead of 15-18 gill-rakers, and 3 dark bars on the body. Apogon sialis (Jordan & Thompson, 1914), type locality Japan, is the senior synonym of Amia cathetogramma Tanaka, 1917, also described from Japan. Apogon pseudotaeniatus Gon, 1986 from the Red Sea, previously misidentifiedas A.bifasciatus Rüppell, is very similar in colour pattern to A. sialis; it differs in having a larger caudal spot, a dark instead of pale intestine, and in several morphometric characters.

  • Description: Photoperiodism involves the use of both absolute measures of day length and the direction in which day length is changing as a cue for regulating seasonal changes in physiology and behaviour so that birth and lactation coincide with optimal resource availability, increasing offspring survival. Induced ovulation and opportunistic breeding is often found in species that are predominantly solitary and territorial. In this study, the photoperiodic reproductive responses of male greater red musk shrews (Crocidura flavescens (I. Geoffroy Saint-Hilaire, 1827)) were investigated in the laboratory. The presence of spermatozoa regardless of the light cycle, suggest that although the shrews are photoresponsive, they may be capable of breeding throughout the year. Significantly greater testicular volume and eminiferous tubule diameter following exposure to a short day-light cycle suggests that these animals may have breeding peaks that correspond to short days. The presence of epidermal spines on the penis indicates that the shrew is likely also an induced ovulator. Flexible breeding patterns combined with induced ovulation affords this solitary species the greatest chance of reproductive success.

  • Description: The study explored the experiences of children who have transitioned into foster care, looking in depth at their level of participation in matters concerning their lives. The researcher was predominantly inspired to conduct this research by children in communities who found themselves falling unintentionally into a system of foster care. There are overt hardships in communities that result in children needing care and protection. Children find themselves faced with abusive circumstances, experiencing loss and being abandoned. There is little research on experiences of children who have transitioned into foster care, on child participation in matters that involve their lives, and research that documents the perspectives of children. Children’s ability to exercise their constitutional right to participate, and making their voices heard regarding their life experiences through their own milieu, have also not received attention. There are several intervention systems put in place by the South African government to aid children in need of care and protection, and systems to place children in conducive environments. These systems are largely focused on placement of the child in need, application for foster care grants, foster parents, and the extension of the foster placement. However, there is very little information regarding the child’s right to participate in matters that involve their lives. The goal of the study was to investigate children’s participation in matters that affect their lives. It was interested in children’s perspectives. The aim was to explore the experiences of children who had transitioned into the foster care system in Breidbach Community in King Williams Town it Buffalo City Municipality. The purpose was to identify gaps, as there is minimal information concerning experiences of children who have transitioned into foster care and on children’s participation as stipulated within section 10 of the Children’s Act 38 of 2005. To be able to achieve the objectives of the study, interviews were conducted with purposefully sampled participants. Data obtained was analysed according to qualitative data analysis procedures. The researcher utilised exploratory, descriptive and contextual research designs. The domain where participants were interviewed was Breidbach, King Williams Town, and Buffalo City under the jurisdiction of the Department of Social Development (DSD) and Child Protection Organisations (CPO). Findings indicate the children lacked education on their right to participate in matters that affect their lives. Furthermore, some professionals did not involve the children in matters that affected them, leading to interventions on matters concerning the children that did not benefit from input by the children. Taking into cognisance of all the relevant information stated above, children’s right to participate in matters involving their lives is as paramount as the involvement of the social workers and the foster parents when determining their placement. A holistic approach has to be used, hence it is primary and recommended that, the investigation, intervention strategies and framework used by social workers in making sure that children in need of care and protection include the perspectives of children who are to be placed into foster care. This will be possible through the participation of a child. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

  • Description: From the onset, it is worthy to note that, nowadays, just as after the independence of most African countries, several writers from the African continent have been preoccupied with the fate of women. This is because, the African continent was since ancient times characterized by certain traditions and cultures which mainly have contributed to the plight of the women. This goes to emphasise that women in most cases are the victims of misdeeds such as early marriage, forced marriage, prejudices, violence, marginalisation, exploitation, discrimination; in short, vices that lead to devalorisation of African women in Africa. Over time, some contemporary French-speaking African writers have responded to the devaluation and valuation of women in their novels using 21st century objective view. With regard to the theme that we decided to address in this research, it is worth knowing that the preponderant task is based on the socio-critical theory, postulated by Claude Duchet. Meanwhile, recourse is also made to the comparative method by Rens, Bod et al. However, since the author’s message could be understood by the reader through the use of some expressions or terms that speak directly to the themes of the research, and that a reader’s role in reading experience cannot be overemphasised, we have been able to also lean on the Reader-response theory of Louise Michelle Rosenblatt. The three methods were used concurrently especially that the analysis of each text is based on how characters are being depicted leading us to realizing that our findings on how the African woman is devalued in the first part of the research, while in the second part of the thesis, our findings demonstrate that a lot of tributes are showered on the African woman due to her numerous outstanding qualities. In effect, our findings also reinforce a significant shift in the narrative that concerns the contemporary view on womanhood. Hence, moving from a dogmatic overconcentration on her lot to the new era woman whose lot is now redefined via the new wave feminist perspective on the negation of the African woman. This could be said to be in line with Amadiume Ifi’s contributions and pioneering work in feminist discourse towards new ways of thinking about sex and gender, the question of power, and women’s place in history and culture. , Pour commencer, il est nécessaire de se souvenir qu’à l’époque actuelle, comme juste après les indépendances de la plupart des pays africains, bon nombre des écrivains venant du continent africain décident de se préoccuper des méfaits sociaux tels que le mariage précoce et/ou forcé, les préjugés, la violence, la marginalisation, l’exploitation, la discrimination, entre autres. Tous ces vices sont issus de la négation de la femme africaine. Ceci se justifie par le fait que le continent africain était depuis l’antiquité caractérisé par certaines traditions et cultures qui ont contribué principalement aux dégâts ci-dessus soulignés subis par les femmes. En effet, nous estimons que beaucoup de femmes sont victimes de ces méfaits qui sont encore pratiqués dans certaines parties de l’Afrique. Avec le temps, certains écrivains africains francophones contemporains représentent la dévalorisation et la valorisation de la femme dans leurs romans en se servant d’une vision contemporaine, celle du XXIe siècle. En ce qui concerne le thème que nous avons décidé d'aborder dans cette recherche, il faut savoir que la tâche prépondérante repose sur la théorie sociocritique, postulée par Claude Duchet. Parallèlement, on a également recours à la méthode comparative de Bod Rens Et ses coauteurs. Cependant, puisque le message de l’auteur pourrait être compris aussi par le lecteur à travers l’usage de certaines expressions ou termes qui sont directement liés aux thèmes de la recherche, le rôle du lecteur dans l’expérience de lecture ne peut pas être surestimé, nous avons également pu nous appuyer sur la théorie de la réponse du lecteur de Louise Michelle Rosenblatt. Les trois méthodes ont été utilisées simultanément d'autant plus que l'analyse de chaque texte est basée sur la façon dont les personnages sont représentés ; ceci nous a amené à tirer nos conclusions sur la façon dont la femme africaine est dévalorisée dans la première partie de la recherche, tandis que dans la deuxième partie de la thèse, nos résultats démontrent que de nombreux hommages sont rendus à la femme africaine grâce à ses nombreuses qualités exceptionnelles. En effet, nos résultats renforcent également un changement important dans le récit qui concerne la vision contemporaine de la féminité. Par conséquent, passer d’une surconcentration dogmatique sur son sort à la femme de la nouvelle ère dont le sort est maintenant redéfini via la perspective féministe par rapport à la négation de la femme africaine telle a été la démarche. On pourrait dire que cela est au diapason avec les contributions d’Amadiume Ifi et avec son travail dans le discours féministe vers de nouvelles façons de penser le sexe et le genre, la question du pouvoir et la place de la femme dans l’histoire et la culture. , Thesis (PhD) -- Faculty of Humanities, School of Languages and Literatures, 2023

  • Description: The purpose of this study is to investigate how Local Economic Development (LED) in Mnquma, with a particular focus on Butterworth, has impacted the alleviation of inequality, underdevelopment and poverty among the poorest of the poor. The aim of the literature review is to analyse the existing knowledge about LED, its impact in the alleviation of inequality, underdevelopment and poverty among the poorest of the poor and the tangible concrete pointer that shows that all key sector role-players are participating in LED. This study is qualitative in nature and employs a case study as the research design. The convenience sampling technique was used to select seven municipal workers and eight members of the community, giving a total of 14 participants. An open-ended interview schedule was used for the face-to-face in-depth interviews in order to collect data from the participants. Collected data was thematically analysed and raw data put set into meaningful segments, codes and categories. Themes were drawn from the responses of the participants and analysed. Some of the findings were that Butterworth municipality was seen as having both urban and rural features. On the other hand, it was found that the municipality did nothing to provide basic services to the people, the towns were dirty and streets lights were not working, there was insufficient representation based on the number of councillors elected under the Mnquma Local Municipality, municipality councillors lack skills, do not give feedback to the communities and need to be capacitated. The study also found that: ward committee members are less involved in the governance of the local municipality; there is a prevalence of high level unemployment and poverty in the municipality. However, there are various expanded Public Works Programmes currently going on in the municipality. The researcher made some recommendations to ensure effective LED with regard to the alleviation of inequality, underdevelopment and poverty among the poorest of the poor of the Mnquma area in the Butterworth municipality. , Thesis (MA) -- Faculty of Business and Economic Sciences, Development Studies, 2021

  • Description: Quantity surveying firms are a crucial part of the construction industry because they are involved in the financial aspects of the projects, and their role and benefits have been documented across various studies. Furthermore, they provide services such as estimating, cost control and feasibility studies in numerous industries and these services are not limited to the construction industry. They are crucial in ensuring that the project proceeds according to budget, quality and time. Despite the noted benefits of quantity surveying firms, there has been a noticeable decline in the survival rate of the firms over the past ten years. It has been documented that several external and internal environmental factors affect the firms and thus have caused a decline in the survival rate. The volatility of internal and external forces that affect the industry has formed the basis of this study. Previous studies have failed to highlight the strategies to reduce threats and utilise opportunities. This study aims to establish common internal and external environmental factors affecting quantity surveying firms and determine these firms’ strategic architecture. A qualitative study was conducted using semi-structured interviews to assess the internal and external environment and strategic nature of Quantity surveying firms. In addition, a thematic analysis was administered to identify themes. The themes that arose from the external business environment were technology, political instability, tendering irregularities, lack of availability of work and the practice of green building. The technology theme highlighted the respondents’ views of the technological environment and the role of BIM and other software. Tendering irregularities threatened prospective tenderpreneurs as the respondents viewed the process as flawed and requiring better regulation. Lack of work was highlighted as a further factor. Although not many respondents mentioned this theme, green building is an emerging theme within the South African market. Two main themes were identified in the internal business environment: fee discounting and human resources. Fee discounting refers to the reduction of fees to secure work, while human resources were highlighted as an important factor and are regarded as the fuel that keeps the organisation running. Owing to the varying nature of factors within the external and internal business environment, it was concluded that there is no formal generic strategy that can be utilised to mitigate internal and external environmental factors. The client relationships were highlighted as an important factor, while client relationships were discussed under the balanced scorecard section of the study. The two main themes derived from the balanced scorecard were the financial perspective and client relationships under customer. Increased revenue per customer and venturing into new markets were the main themes mentioned within the financial perspective. The importance of nurturing client relationships was identified as an important factor under the customer section of the balanced scorecard. iii | P a g e The findings of this study will assist the stakeholders within the built environment in determining common internal and external environmental issues facing the industry. The recommendation will assist stakeholders in establishing probable solutions that can be implemented to overcome these challenges. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

  • Description: With the substantial number of new malware variants found each day, it is useful to have an efficient way to retrieve Indicators of Compromise (IOCs) from the malware in a format suitable for sharing and detection. In the past, these indicators were manually created after inspection of binary samples and network traffic. The Cuckoo Sandbox, is an existing dynamic malware analysis system which meets the requirements for the proposed framework and was extended by adding a few custom modules. This research explored a way to automate the generation of detailed network-based IOCs in a popular format which can be used for sharing. This was done through careful filtering and analysis of the PCAP hie generated by the sandbox, and placing these values into the correct type of STIX objects using Python, Through several evaluations, analysis of what type of network traffic can be expected for the creation of IOCs was conducted, including a brief ease study that examined the effect of analysis time on the number of IOCs created. Using the automatically generated IOCs to create defence and detection mechanisms for the network was evaluated and proved successful, A proof of concept sharing platform developed for the STIX IOCs is showcased at the end of the research.

  • Description: Elucidation of evolutionary factors that enhance protein thermostability is a critical problem and was the focus of this work on Thermus species. Pairs of orthologous sequences of T. scotoductus SA-01 and T. thermophilus HB27, with the largest negative minimum folding energy (MFE) as predicted by the UNAFold algorithm, were statistically analyzed. Favored substitutions of amino acids residues and their properties were determined. Substitutions were analyzed in modeled protein structures to determine their locations and contribution to energy differences using PyMOL and FoldX programs respectively. Dominant trends in amino acid substitutions consistent with differences in thermostability between orthologous sequences were observed. T. thermophilus thermophilic proteins showed an increase in non-polar, tiny, and charged amino acids. An abundance of alanine substituted by serine and threonine, as well as arginine substituted by glutamine and lysine was observed in T. thermophilus HB27. Structural comparison showed that stabilizing mutations occurred on surfaces and loops in protein structures.

  • Description: In post-development theory, ubuntu is often cited as an example of an “alternative to development”. This article investigates whether ubuntu can play this role and what to think of the demand for alternatives to development in general. In order to do this, the paper fi rst deals with central aspects of postdevelopment theory and the debate about ubuntu. Although the concept fi ts well into a post-development perspective, the attempts to contrast ubuntu with Western ideas and ways of life are often fueled by the desire to rekindle an original, pre-colonial, authentic African philosophy. Yet discourses on Africa are always embedded in Western discourses, so this opposition reproduces precisely those dichotomies it aims to fi ght. More generally, this also holds true for the idea of “alternatives to development”, which postulate an essential opposition to “development”. This, however, denies claims for equal rights and participation at the root of demands for “development”. The struggle for these claims cannot be fought beyond the existing global order. Instead of engaging in romanticizing projections about an Africa beyond “development”, people’s views and needs should be taken as the starting point for the struggle against injustice and inequality.

  • Description: The effects of melatonin, a known free-radical scavenger, on paracetamol in the presence of UV irradiation was studied by use of HPLC. The experiments were performed in air and nitrogen. The results show that the rate of photodegradation of melatonin is faster in air than in nitrogen whereas that of paracetamol is similar in air and nitrogen. When the two drugs were combined, melatonin retarded the degradation of paracetamol for up to 6h in the presence of nitrogen. However, in the presence of air melatonin rapidly enhances the photodegradation of paracetamol. This study shows that a combination of melatonin and paracetamol in the presence of air and UV irradiation can lead to rapid inactivation of both agents, thus raising important concerns about the possible use of melatonin as sunscreen

  • Description: Histological examination of gametogenesis revealed that the current staging criteria used to assess gonadal recrudescence of the redeye labeo, Labeo cylindricus, were adequate. Gametogenesis was qualitatively similar to that of freshwater teleosts with a clearly defined seasonal reproductive cycle. L. cylindricus undergoes seasonal gross morphological and cytological gonadal changes with previtellogenesis dominating during the winter, vitellogenic development during spring and summer culminating in large-scale spawning at the end of summer. Post-spawning mass atresia of oocytes was evident in autumn. The histological data presented support macroscopical evidence that L. cylindricus is a synchronous iteroparous spawner, reproducing over a short period each year throughout its life-span.

  • Description: Commercial drivers have been identified as eliciting behaviours that promote non- communicable diseases and road traffic accidents. The aim of the study is to determine the prevalence and pattern of alcohol use, smoking and physical inactivity among commercial taxi drivers in Buffalo City Metropolitan Municipality, South Africa. A cross-sectional study was conducted among 403 commercial drivers using the face-to-face interviews method. The WHO STEPwise questionnaire was used to obtain the demographic data, self-reported rate of alcohol consumption, tobacco use and physical inactivity. The participants’ mean age was 43.3 ± 12.5 years. About 30% of the participants were daily smokers, 37% consumed alcohol regularly and only 18% were physically active, whilst 82% were physically inactive. The prevalence of alcohol use, smoking and physical inactivity is high among commercial drivers in East London. Workplace health education on the health effects of these lifestyles’ risky behaviours on individuals and the general public should be given to the drivers.
