- Description: Schistosomiasis, often known as bilharzia, is a parasitic water-borne disease caused by trematode flatworms of the genus Schistosoma. In 76 endemic countries, including 46 in Africa, over 800 million individuals are at risk of contracting the disease. This study examined the influence of water physicochemical properties, vegetation type and community knowledge, attitudes and practices (KAP) on the distribution and habitat preference of schistosomiasis intermediate host snails in the communities of Kariega and Kwa Nobuhle, in Nelson Mandela Bay. Methods. A quantitative cross-sectional research design approach was employed in this study. Data for the water physicochemical properties was collected over different seasons over a 9-month period. Eight sampling sites were selected based on their proximity to residential areas. A simple dip method was used for surface water samples and measurements done using a Bante 900P multiparameter meter, Macherey Nagel PF-12 plus, and hardness meter. A 300 μm mesh scoop net on a metal frame was used to capture snails. At each sample site, the predominant plant species were gathered and transported to experts in the Botany Department at Nelson Mandela University for identification. The composition and percentage cover of vegetation were visually estimated and documented. A structured questionnaire was used to elicit responses from 380 participants for the pre- and post-intervention KAP study, using the interview format. Data was analysed using R software (version 4.3.1) and Microsoft Office 365 Excel (2019 version). Results. Freshwater snails were found in all eight water bodies studied; however, schistosomiasis intermediate host snails were only found in three of them while the prevailing species in the study sites were Physa snails. There was no correlation between the number of snails and turbidity (r=-0.070). However, a negative and weak correlation existed between snails and DO (r=-0.185), hardness (r=-0.210), pH (r=-0.235), TDS (r=-0.236), EC (r=-0.240), salinity (r=-0.242), and temperature (r=-0.273). There was also a negative correlation between snails and vegetation coverage (r=-0.127). Of the 380 study participants, only 8.7% were aware of the disease pre-intervention. The paired samples t-test results demonstrate a difference (7.2 ± 2.5) in knowledge scores, and the improvement in knowledge levels post-intervention is statistically significant (p<0.001). Conclusion. The study discovered an abundance of Physa snails; considering their biological characteristics and ability to endure, these snails could potentially serve as a biological control agent in locations where the , Thesis (MSc) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2024

- Description: This study is aimed at determining the role that hashtag activism has played in advocating against gender-based violence (GBV) and promoting perpetrator accountability. The study used major GBV hashtags such as #MeToo, #WhyIStayed and #AmINext to investigate how effective these hashtag movements have been in breaking the silence around GBV and fighting against GBV. The study made use of both qualitative and quantitative research methodology, which was useful to gain a deeper understanding of GBV and all the social and cultural practices that perpetuate it. Qualitative data were collected by means of interviews and tweets under the selected hashtags. An online survey questionnaire was used to collect quantitative data. The data provided an understanding of the complexities surrounding GBV and people’s views on hashtag activism and GBV. Through the data analysis, the study found that hashtag activism has been effective in changing dominant discourses, advocating against GBV, creating awareness and solidarity around GBV issues, and promoting perpetrator accountability. The study calls for a global collective effort to develop, record and archive feminist initiatives so that all the structural conditions which enable and perpetuate sexual violence are exposed and cannot be forgotten or ignored. Future research should look into how harmful societal norms can be challenged and how the effectiveness of hashtag movements can be enhanced , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024

- Description: This research studied the role of microfinance in women empowerment in Gqeberha, in Nelson Mandela Bay, Eastern Cape, South Africa. Various development strategies and approaches have been devised across the world, aimed at empowering women and eradicating poverty, particularly in developing countries. One of these development strategies is microfinance. Microfinance has provided financial assistance through loans to people, unable to access formal financial banks. Empowering women to participate fully in their economies is not only essential to building economies but to achieving the internationally agreed goals for development, human rights and sustainability. The inclusion of women empowerment and poverty alleviation in the Millennium Development Goals and Sustainable Development Goals demonstrates the importance of poverty alleviation (SDG1) and women empowerment (SDG5) in the development of economies across the world. This qualitative research study collected data, using semi-structured questionnaires and interviews with 30 beneficiaries of MFIs and three MFI managers in Gqeberha. The sampling method used were non-probability purposive sampling, and the data were analysed through content analysis and descriptive statistics. The results suggest that microfinance through micro-loans and micro-business loans has had a positive role in the empowerment of women through the ease of access to finance through small loans. However, a gap exists in the market for long-term loans which could aid with starting small businesses and give the beneficiary more financial independence, improving their livelihood. It is recommended that MFIs across Gqeberha offer loans in the form of start-up capital and financial advice or education. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2024

- Description: This study investigates the intricate dynamics of music within the umgidi initiation ceremonies among the amaMpondo, focusing on the interplay between traditional and modern popular music. The study explores the cultural foundation of the umgidi ceremony, emphasising its transformative significance and the evolving influence of modern popular music, particularly among the youth. A comprehensive literature review follows, contextualising the amaMpondo, their cultural practices, and the complex relationship between traditional and popular music in the broader South African music scene. The study adopted a qualitative ethnographic approach, including participant observation and individual interviews, to explore the impact of modern popular music on traditional elements during umgidi initiation ceremonies. Thematic analysis was employed for data interpretation, ensuring a systematic exploration of patterns and meanings. Ethical considerations were meticulously addressed, emphasising protecting participants' rights and cultural sensitivity. The study's findings highlighted the multifaceted roles of music during umgidi initiation ceremonies. Music is a powerful medium for cultural expression, communication, and communal celebration. The call-and-response format, rhythm variations, and the influence of modern genres such as Gqom and Amapiano were explored. Community attitudes toward integrating modern popular music reveal diverse opinions, ranging from full embrace to resistance. In summary, this study contributes to understanding the evolving dynamics of music in umgidi initiation ceremonies among the amaMpondo. The study provides a nuanced exploration and a roadmap for future research, community engagement, and policy considerations by combining cultural insights, literature review, methodological rigour, and community perspectives. , Thesis (MMus) -- Faculty of Humanities, School of Visual and Performing Arts, 2023

- Description: The issue of poor Solid Waste Management (SWM) continues to be a challenge in the world, as waste is always generated through daily human activities, and it needs to be properly managed. This study aimed to examine the role of solid waste management in enhancing the urban settlements’ economic development. Guided by the findings and the Circular Economy Model (CEM), the study proposed a waste management framework that can be used to achieve Integrated Solid Waste Management (ISWM) while permitting economic development for the urban poor. The study utilized the mixed methods approach, which involves the collection and the integration of both quantitative and qualitative data to scrutinize the study from multiple points of view to improve accuracy. A mixed methodology with a structured questionnaire was employed. Data was obtained from 256 respondents out of a total of 303 households and one landfill was targeted. The research findings are therefore based on an 84% response rate of the targeted sample size. The study assessed the role that solid waste management can play in economic development using Walmer E, Summerstrand, Gqeberha Central and Arlington Landfill in Nelson Mandela Bay Municipality (NMBM) as the case study areas. The Statistical Package for the Social Sciences (SPSS) was used to generate the descriptive summary statistics for the survey results, and it was also used to analyse the frequency, the correlation, and the factor analysis. The factor analysis was tested using Kaiser-Meyer-Olkin (KMO) and the Initial Eigenvalues, while the data correlation was examined using the Chi-Square Tests and the Symmetric Measures. The narrative thematic method was used for qualitative data, where raw data becomes the actual data presented. This study proves that the current waste management practices in the NMBM area are not sustainable as there is an increasing demand for landfills and the land filled waste has environmental challenges. Therefore, a new waste management framework for tackling these difficulties is proposed with the aid of study findings and CEM. Various theories of economic development and waste management were used and CEM was found more applicable, since it promotes the relationship between waste management systems and economic development. The proposed framework involves four significant factors that were found to positively influence waste to wealth. Those are; social behaviour, education, economic feasibility and governance of Municipal Solid Waste Management (MSWM). The Waste To Wealth (WTW) framework might help to improve solid waste management and shore up the present urban economy. The proposed framework would be applicable not only in the Nelson Mandela Bay Municipality (NMBM) but also in South Africa and in other countries. , Thesis (DPhil) -- Faculty of Engineering, the Built Environment, and Technology, School of Built Environment and Civil Engineering, 2024

- Description: South Africa is experiencing an exponential growth of the street trading business. Subsequently, in every corner of the central business a street trader is found and Kouga Local Municipality is no exception to this phenomenon. For this reason, the study investigated the contribution of street trading in sustaining livelihoods in Kouga Local Municipality. This was achieved by investigating the factors that contribute to street traders’ sales income, thereafter, determining the impact of income derived from street trading on the household. Furthermore, the study investigated the socio-economic status of street traders in Kouga Local Municipality to understand the role played by the Municipality in sustaining the livelihoods of street traders. In achieving the objectives the study employed a mixed methods research design, incorporating qualitative data collection and a combination of content and statistical data analysis. In collecting the data, the study included participants who were engaged in street trading in Kouga Local Municipality. Participants eligible to partake in the study were over 18 years of age. The study targeted a sample size of 30 participants. With regards to the data collection tool, a closed ended questionnaire was used to solicit the information. Physical interviews were deemed necessary because of the limited educational background of many street traders. The findings revealed that the street traders derived an income greater than R945.00 per month. This proved that street trading had the capability to mitigate poverty in Kouga Local Municipality, as the most of the street traders earned a sufficient income to live above the food poverty line, which equates to R663 and also the lower bound poverty line, which equates to R945.00. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

- Description: The purpose of this study is to investigate the relationship between employees' perception of environmental sustainability and pro-environmental behaviour within the corporate business environment of South Africa and its influence on a company’s corporate sustainability efforts. The study will follow a case study approach involving the employees of a corporate state-owned company in the logistics industry of the Nelson Mandela Bay area. In doing so the study attempts to better understand why enterprises, in their attempts to promote corporate sustainability, face challenges in aligning their variety of sustainability strategies, policies, and initiatives with employees' willingness to implement these measures or engage in pro-environmental behaviour in the workplace. To delve deeper into this issue the study also explores potential reasons for differences in perceptions by examining potential correlations between perceptions of environmental sustainability and pro-environmental behaviour, considering demographic factors such as gender, age, education, and work experience. The collective findings of the study underscore a positive relationship between employees’ environmental perception and their engagement in pro-environmental behaviour. This suggests that individuals who express a higher degree of concern for environmental issues are more likely to adopt and engage in environmentally-friendly behaviours. However, a notable disconnect was identified between awareness and action, highlighting variability in the extent to which perception translates into active pro-environmental behaviour. While environmental perception serves as a strong motivator, there is evident room for improvement in translating these concerns into concrete actions within the corporate setting. These insights emphasise the importance of addressing both attitudes and behaviours in the context of environmental sustainability. Thus, to enhance corporate sustainability efforts, it is imperative for companies to bridge the gap between environmental perception and action among their employees. The demographic variables (gender, age, education, and work experience) showed no significant influence on environmental perception or pro-environmental behaviour in this study, however these empirical findings challenge common findings in the existent literature, thus emphasising the need for a more nuanced understanding of the subject, within specific contexts. Recommendations for future studies include: larger sample sizes for robust findings; exploration of the influence of academic disciplines; consideration of household income and cultural differences; and broadening the study to multiple departments in order to gather more , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

- Description: As the landscape of higher education undergoes a shift toward a combination of online instructional methods and traditional in-person engagement, a creative approach becomes essential in ensuring student success. The research aims to explore how visual storytelling can enhance the online learning experience at Nelson Mandela University (NMU), thereby improving the effectiveness of teaching and knowledge acquisition. This study delves into the Learning Experience Design (LXD), a blend of instructional design, design thinking, and user experience design, within the teaching community of Nelson Mandela University and the broader South African context. Employing a mixed-method approach, qualitative data from interviews identified themes such as the improvement of LXD, challenges in the design process, and the utilization of visual storytelling. Quantitative analysis revealed that students primarily used the university learning management system (Moodle) for accessing resources, grades, and reviewing tests, with limited engagement in online learning activities. Lecturers expressed concern about Moodle’s functionality, a need for enhanced design support, and the necessity for training in the transition to digital learning. While lecturers recognized the potential of visual storytelling in enhancing engagement and knowledge retention, they emphasized the importance of support for the seamless integration into teaching. Students acknowledged the positive role of visual storytelling in improving their learning experience but highlighted areas of improvement, such as regular updates, increased visual interaction options, and the inclusion of information graphics to explain concepts. A design thinking process informed the development of instructional design interventions, leading to the creation of a prototype Moodle course shell and resources. This initiative aims to empower lecturers to enhance the learning experiences independently with the support of professional LXD services. The research findings suggest that visual storytelling indeed improves LXD, emphasizing the need for established support systems and resources at the university to equip lecturers for successful integration. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2024

- Description: A foreign company providing services in South Africa may, depending on the nature of the services rendered, do so directly or through its branch. Where the foreign company or its branch in providing such services falls within the ambit of the compulsory registration requirements set out in section 23, the foreign company or its branch is obliged to register as a vendor and the provisions of the VAT Act thereafter apply to such foreign company or its branch. The nature of the services rendered determine whether it is the foreign company or its branch which is obliged to register as a vendor. Where the services rendered constitute 'electronic services' falling within the scope of paragraph (vi) of the enterprise definition, it is the foreign company which must register as a vendor and not its branch. In all other cases (apart from the supply of 'imported services'), where services are rendered in South Africa, it is the branch which must register as a vendor, unless it is a 'dependent agent' of the foreign company as envisaged in the Wenco case 1, in the sense that it has no clients of its own in South Africa and supplies only services on behalf of the foreign company. In such a case the branch does not conduct an 'enterprise' and its foreign company must register as a vendor. Where a dependent branch supplies services to the foreign company's main business abroad, the supply is not zero-rated in terms of section 11 (2)(o) as, on the authority of the Wenco case, the provisions of section 8(9) have no application in such a case. Generally, where a foreign company or its branch supplies services in South Africa and is obliged to register as a vendor, output tax is levied in terms of section 7(1 )(a) and an input tax deduction may, in certain circumstances, be claimed provided that the foreign company or its branch is actually registered for VAT. In the case of 'imported services' it is the recipient which is liable for VAT thereon in certain circumstances. , Thesis (LLM) -- Faculty of Law, 2024

- Description: It is understood that, for us humans to communicate with one another, we need language. Communication thus has a close relationship with society. But language changes and it has many varieties. On the one hand we have the standard variety of a language which is mostly used in formal situations, and on the other hand we have other varieties, which are mostly used in informal situations. Slang serves as an example of the latter and is chiefly used by adolescents – individuals between the ages of 13 and 19. As Saal and Lawrence (2019: 24) put it: young people are the agents of linguistic change. The researcher finds the language of teenagers quite interesting seeing that he is a teacher who frequently comes across words or phrases he has not heard or does not know the meaning of. The goal of this study is thus to investigate teenage language as phenomenon, with special reference to slang. This study examines slang words and expressions as they occur among teenagers in two Nxuba (formerly Cradock) schools, as well as find out why, when, and when the research group will not make use of slang. Nxuba forms part of the Inxuba Yethemba Municipality in the Eastern Cape. During the study general linguistic phenomena that occur among the teenagers in the given town are also investigated. These phenomena are analysed using the phonetic, phonological, morphological, syntactic, semantic, and lexical levels of variation. This study follows a qualitative approach with the help of questionnaires, direct observation, and focus group interviews as data collection methods. It was found that teenagers are highly creative and create novel words or give new meanings to words that already exist in the standard variety. The reasons why teenagers make use of slang is, among other things, to ease communication, for the fun of it, secrecy, and to enrich the standard variety. Slang is mostly used in informal situations and tends to be avoided in the presence of older persons, at church, and when doing schoolwork. There are also various linguistic phenomena that appear in teenagers’ general language usage: borrowing, reduction, homonyms, polysemes, and various phonological phenomena, among other. , Thesis (MA) -- Faculty of Humanities , School of Language, Media and Communication , 2024

- Description: There have been numerous claims regarding how quality management systems facilitate the implementation of Total Quality Management (TQM) among Government Implementing Agents, particularly within the Eastern Cape Department of Public Works and Infrastructure. However, the success rate of TQM implementation in ECDPW projects varies. This study aims to investigate the implementation of TQM within these construction projects. Additionally, five secondary objectives were established to further this investigation. Utilizing a quantitative research approach, data obtained from a semi-structured questionnaire survey was analyzed. The analysis was based on responses from 44 out of 50 questionnaires distributed. Implications: The practical implication of this study lies in identifying the implementation of TQM among Governmental Implementing Agents, particularly within the Eastern Cape Department of Public Works, and understanding the challenges they encounter. The theoretical implications encompass contributing to existing studies that validate quality comprehensively within ECDPW construction projects and suggesting ways they can effectively implement TQM across their processes. The research findings confirmed the challenges and difficulties experienced during the various phases—pre-construction, construction, and post-construction—of projects managed by the Eastern Cape’s Department of Public Works. It was evident that Total Quality Management lacks robust implementation within ECDPW construction projects, directly impacting project quality and the effective execution of quality management systems. A key limitation of this study is the absence of data collection on the professional backgrounds and years of experience of the study participants. During pilot testing, it was found more suitable to identify job roles rather than professional backgrounds. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Built Environment and Civil Engineering, 2024

- Description: This study explores sociolinguistic practices such as translanguaging, in which “diglossia is presumably allowed without isolation and bilinguals’ linguistic resources are viewed as an integrated system.” While bilinguals select and deploy particular features from their linguistic repertoires for meaning-making, translanguaging is widely used by teachers and students in multilingual classroom settings, as guided by the Personnel Administrative Measures (PAM). Translanguaging also provides a path for students to bring in and use their linguistic repertoires to produce the required learning outcomes, perform their identities and facilitate language development. Thus, this study is based on the view, subscribed to in contemporary sociolinguistics, that monoglossic language ideology is embedded in modes of oppression steeped in neoliberal, colonial and linguistic purist forms”. The purpose of the study was to make a case for the implementation of translanguaging in the written assessment of isiXhosa/English bilingual high-school learners in the Eastern Cape. The study employed a qualitative approach in the form of document analysis, whereby the researcher used selected Grade 12 question papers to find out how often translanguaging occurred. This was done by illustrating how examiners are moving past forms of linguistic purism when setting papers. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024

- Description: Invasive species can impact island ecosystem processes by altering species interactions through direct competition for the same resources or by predation on insular species. Seabirds on sub-Antarctic islands are naïve to any new predators and are most at risk of local extirpation. Successful eradications of invasive mammals have yielded positive ecological responses from several seabird species. On sub-Antarctic Marion Island, populations of burrowing petrels, largely targeted by Feral Cats Felis catus, have indicated slow recovery despite the successful eradication of cats in the early 1990s. House Mice Mus musculus, have since proliferated on Marion Island, aided by a warmer climate, and are severely impacting several defenceless populations of burrowing petrels. In this thesis, I investigated the contemporary breeding productivity and diet of Brown Skuas Catharacta antarctica. At Marion Island, Brown Skua breeding productivity was associated to diet, which varied between years. Skuas feeding mostly on burrowing petrels exhibited higher breeding success than pairs mostly feeding on penguins. Higher contributions of burrowing petrels were seen in the contemporary diet of skuas compared to previous diet work. The importance of penguin prey compared to their 1980 and 2010/11 diet, was largely reduced during the 2021/22 and 2022/23 breeding seasons (53 and 51%, respectively) despite a historically high dependence on this prey (78% in 1980 and 67% in 2010/11). Penguin populations have been decreasing at the island and this may be reflected in the current skua diet. Breeding productivity was not influenced by the other factors tested, i.e. weather data (daily minimum, average and maximum air temperature; daily minimum, average, maximum wind speed; daily precipitation), distance to closest penguin colony, species of penguin or number of conspecifics in a 100 m radius around the nest. Brown Skuas breeding on Marion, Gough and Mayes islands were also used as biosamplers of burrowing petrels. These birds form a large part of the skua diet and are reflected in regurgitated skua pellets. Temporal comparisons for Marion Island indicated significant changes in burrowing petrel composition since the 1980s. Blue Petrels Halobaena caerulea and Salvin’s Prions Pachyptila salvini remained the highest contributors of skua pellets, but their proportions differed with three-fold increase in Blue Petrel and 25% decrease in Salvin’s Prion remains compared to previous studies. Further, my study indicated that smaller species of burrowing petrels such as the storm-petrels and diving petrels may be returning to Marion Island, 30 years after the eradication of cats. Pellet analyses at Marion, Gough and Mayes islands also indicated that skua diet may underrepresent larger species of petrels and soft-bodied prey. Despite these limitations, skua diet can indicate the presence of burrowing petrels during summer months, more so at Marion and Mayes islands than Gough Island, where pellet collection is difficult due to dense vegetation. Prey remains, such as wings in middens, may be a more appropriate method to investigate skua diet at Gough Island. Dominant burrowing petrels indicated by pellets at each island generally reflected the most abundant breeding species; Blue Petrels and Salvin’s Prions at Marion Island, Great Shearwaters Puffinus gravis and prion Pachyptila spp. at Gough Island, and Blue Petrels and Slender-billed Prions Pachyptila belcheri at Mayes Island. Pellets provide a non-invasive method for studying species of burrowing petrels that are challenging to monitor. This method is appropriate for studies conducted during summer months, while other studies (e.g., observations, camera traps, acoustic recordings and genetics) may be more reflective of the presence of burrowing species that breed in winter or could be used in combination with skua pellets during summer months. Population monitoring is an important part of conservation as it provides insights into population change. This thesis adds to the baseline data in terms of breeding productivity and updated trophic ecology of Brown Skuas, which will be used to inform the recovery of burrowing petrels once mice have been eradicated from Marion Island. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2024

- Description: Olu phando lugxile ekuphononongeni ukukhumbula nokulibala kwii-othobhayografi ezibhaliweyo ekaMagona (1995) noMtuze (1976). Ii-othobhayografi eziza kusetyenziswa luphando zithi: Indlel’ Ebhek’ Enkundleni ngokukaPeter Mtuze (1976) nethi, Kubantwana Babantwana Bam ngokukaSindiwe Magona (1995). Xa kusenziwa uphando kuza kuhlalutywa amanqanaba okukhumbula nokulibala ukusukela ebuntwaneni ukuya kutsho ebudaleni kubabhali bee-othobhayografi. Uhlalutyo luza kube lugxininise ekujongeni iinkumbulo zababhali, luhamba nabo ngokwamanqanaba okukhula kwabo, amanqanaba okukhumbula nokulibala njengoko bekhula. Uphando luza kungqiyama ngengcingane yokukhumbula nokulibala eyasungulwa nguEbbinghaus (1885) kuphando lwakhe awayelwenza. Iinjongo zikaEbbinghaus ongumsunguli wengcingane zokuzisa ulwazi ngengcingane yokukhumbula nokulibala kukubonisa indlela ukulibala okwenzeka ngayo. UEbbinghaus uye wasebenzisa ikhevu yokulibala ukuvelisa banzi ingcingane. Lo msunguli wale ngcingane yokukhumbula nokulibala uthi, le khevu yokulibala ibonisa ukwehla kwezinga lokukhumbula okanye iqondo lokukhumbula xa luthe ulwazi lwalahleka ngenxa yokungenziwa kwamatiletile okulugcina nokukhunjulwa ngumninilo. Oku uEbbinghaus (1885) ukucacisa kwincwadi yakhe ethi Memory (1850-1909). Uphando njengokuba lubandakanya okwenzeka kwingqondo luza kube lukhatshwa yingcingane yokuqonda. Ingcingane yokuqonda yingcingane enkulu nengcingane ethe yajongwa kakhulu ziingcali ezininzi, ikwaphuhliswa ziingcaphephe ezininzi nezifundiswa. Uphando lukhethe ukuvelisa uEbbinghaus ukubonisa ingcingane yokukhumbula nokulibala, kodwa yona iphefumlelwe ziingcaphephe ezininzi mandulo. NgokukaGuyer (1998:1) enye yeengcaphephe abhale ngayo ethetha ngengcingane yokukhumbula nokuqonda nguKant (1724-1804) owaziwa ngomsebenzi wakhe othi: The Critique of Pure Reason. Lo msebenzi ucatshulwe apha kulapho uKant (1724-1804) athetha ngendlela yokuqonda ulwazi nokuzisa izizathu. Emva koko iingcali ezininzi ziye zaqhuba nengcingane yokuqonda ukuza kuthi ga kule mihla. Oku kuquka ingcali uChart (2017) obhale ngengcinane yokuqonda ngokwale mihla. Uphando luza kuvelisa ingcingane yesini njengengcingane ekhaphayo. Ingcingane yesini iza kusetyenziselwa ukuthelekiswa kwababhali bee-othobhayografi kujongwa indlela yokukhumbula nokulibala kugudlwe isini. Ngonyaka we-1955 uMoney (1955) waye wapapasha iphepha kunye nabo asebenza nabo kwiSebe lezeNgqondo uJoan G. Hampson nomyeni wakhe uJohn L. Hampson apho babeqala ukwazisa ngenkquleqhu yendima yesini besithi: Zonke izinto azithethayo okanye azenzayo umntu ukuze azichaze njengenkwenkwe okanye indoda, intombazana okanye ibhinqa, ngokulandelelanayo, zibizwa ngokuba ziindima zesini. Kulapho uMoney (1955) wathi wasungula khona le ngcingane yesini eza kuthi ithathe inxaxheba kolu phando ngokubonisa ukukhumbula nokulibala kwisini. Olu phando luza kuthi lwenziwe ngohlobo olubizwa ngokuba yintyilazwi. Intyilazwi ilunge kakhulu kolu hlobo lophando kuba luphando olufundisayo njengokuba luvelisa unobangela wokukhumbula nezizathu zokulibala. Intyilazwi iyagqitha ize ijonge amava ababhali, indlela abazicacise ngayo iinkumbulo zabo nendlela abazibhale ngayo iiothobhayografi zabo bechaza iziganeko zokukhula kwabo. Olu hlobo luza kube lungajongi zigrafu okanye manani kodwa lujonga kakhulu indlela yokuhlalutya oko kubhaliweyo. Iincwadi ezisetyenziswa kuphando ziza kushwankathelwa zibuye zihlalutywe ngokwendlela yokuhlola iziganeko zokukhumbula nokulibala kwababhali. , Thesis (MA) -- Faculty of Humanities, School of Langauge, Media and Communication, 2024

- Description: Olu phando lugxile ekuphononongeni ukukhumbula nokulibala kwii-othobhayografi ezibhaliweyo ekaMagona (1995) noMtuze (1976). Ii-othobhayografi eziza kusetyenziswa luphando zithi: Indlel’ Ebhek’ Enkundleni ngokukaPeter Mtuze (1976) nethi, Kubantwana Babantwana Bam ngokukaSindiwe Magona (1995). Xa kusenziwa uphando kuza kuhlalutywa amanqanaba okukhumbula nokulibala ukusukela ebuntwaneni ukuya kutsho ebudaleni kubabhali bee-othobhayografi. Uhlalutyo luza kube lugxininise ekujongeni iinkumbulo zababhali, luhamba nabo ngokwamanqanaba okukhula kwabo, amanqanaba okukhumbula nokulibala njengoko bekhula. Uphando luza kungqiyama ngengcingane yokukhumbula nokulibala eyasungulwa nguEbbinghaus (1885) kuphando lwakhe awayelwenza. Iinjongo zikaEbbinghaus ongumsunguli wengcingane zokuzisa ulwazi ngengcingane yokukhumbula nokulibala kukubonisa indlela ukulibala okwenzeka ngayo. UEbbinghaus uye wasebenzisa ikhevu yokulibala ukuvelisa banzi ingcingane. Lo msunguli wale ngcingane yokukhumbula nokulibala uthi, le khevu yokulibala ibonisa ukwehla kwezinga lokukhumbula okanye iqondo lokukhumbula xa luthe ulwazi lwalahleka ngenxa yokungenziwa kwamatiletile okulugcina nokukhunjulwa ngumninilo. Oku uEbbinghaus (1885) ukucacisa kwincwadi yakhe ethi Memory (1850-1909). Uphando njengokuba lubandakanya okwenzeka kwingqondo luza kube lukhatshwa yingcingane yokuqonda. Ingcingane yokuqonda yingcingane enkulu nengcingane ethe yajongwa kakhulu ziingcali ezininzi, ikwaphuhliswa ziingcaphephe ezininzi nezifundiswa.

- Description: Architectural, engineering, and construction education is fragmented, and there is no collaboration between disciplines during an architectural design project in the design studio. There is a lack of co-creation of knowledge in an interdisciplinary collaborative environment where students use critical reasoning, self-reflection, and critical action, essential skills required to become 21st century global citizens. Therefore, students from the built environment are being prepared contrary to the highly collaborative nature of the industry they are entering upon graduation. The purpose of this study is thus to determine whether adopting a digital interdisciplinary collaborative Building Information Modelling (BIM) environment in which architectural design projects promote criticality in undergraduate exit-level students. A cohort comparison study was used as a method to collect qualitative data. The 2022 cohort used the traditional design process, whereas the 2023 cohort used the BIM process, which supported interdisciplinary collaboration. Both cohorts engaged in a project and student narrative self-reflection essay. Fourteen students from the 2022 and 2023 cohorts participated in the study. The work was analysed using three cycles of coding. The first cycle focused on linguistic acts, followed by the second cycle that looked for evidence of critical reasoning, self-reflection, and action. The third cycle was based on the Habersian validity claims of truth, comprehension, and sincerity. The work of both cohorts was analysed, and findings included the following: relationships; information; emotional reasoning, and digital environment. Based on the research findings, it can be concluded that the BIM process as teaching strategy promotes a higher level of criticality in students than the traditional design process. In conclusion, this research not only contributes to promoting criticality improvement in students but also enriches the existing body of knowledge relative to BIM adoption in AEC education. Moreover, it offers practical guidance for educators to assess and enhance students' critical thinking skills, ultimately advancing the field of interdisciplinary education in the digital era. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, School of Built Environment and Civil Engineering, 2024

- Description: The public sector construction industry aims to deliver infrastructure services to its client satisfactorily. However, the public sector is notorious for delivering projects that are over budget, finish years behind schedule, and are of poor quality. Value management is one way to address these challenges. This research aimed to examine the level of awareness and implementation of value management within the public sector and the benefits thereof. In this qualitative study, interviews were employed to gain insight into the level of awareness of value management within the public sector department in the Eastern Cape. A total of ten professionals in the public sector working for the Department of Public Works were purposively selected to be interviewed and the secondary data was sought through document analysis . The data was thematically analysed. The South African government requires a strategic change that will help improve awareness of value management in government infrastructure projects in South Africa which will pave the way for the full implementation of VM. The study found that the obstacle to adopting value management for public projects was the lack of knowledge and practice of value management. It was also found that the respondents were keen to implement value management and saw it as part of an important step in the planning stage of a project as it would save the department time and money. In order to improve the performance of construction projects, there is a need to adopt innovative ideas and solutions that will work for South African construction industry. Value management is one way to improve the performance of construction projects. VM should be considered at a strategic level in public sector departments to improve its applicability to meet client’s objectives. The major goal of the VM is to ensure that projects are delivered to the best function at the lowest total life cost achievable. The satisfaction of clients is a key factor of construction project success. Value Management strives to address problems which may arise such as budgetary constraints trying to decrease unnecessary costs towards the project but without causing changes to quality of the finished product. Value management is believed to be a cost-cutting exercise as perceived by many but the most importantly it focuses on function of an element or project. This means that the project is procured at the lowest possible cost by utilizing multiple cost control mechanisms without compromising the project's value and function. Value management has proven to be a practical management strategy for improving value for money, creating a better focus on project objectives, working toward more effective design, and identifying wasteful expenses due to unneeded design, material, labor, and machine. To optimise the usage of value management and to improve project performance, there is a need to adopt new concepts like value management that will work for the South African construction sector. , Thesis (MSc) -- Faculty of Engineering, the Built Environment, and Technology, School of Built Environment and Civil Engineering, 2024

- Description: Cannabis sativa L. (Family Cannabaceae) has continued to attract much interest among natural product scientists in recent time because of its known medicinal values and remarkable chemical diversity. This study reports the investigation of C. sativa cultivated in the Eastern Cape Province of South Africa, with a view to obtaining its chemical fingerprint and isolating compounds from its stem bark for possible biological applications. Fresh and dried leaves, flowers, stem barks and roots of two Cannabis cultivars were obtained under permit NO. PIA-HP-EC-2022-0023. The fresh and dried plant materials were extracted for their essential oils (EOs), using hydro-distillation method on a Clevenger apparatus set at optimum extraction condition. The EOs were characterized by a gas chromatography coupled to a mass spectrometer (GC-MS). The chemical components of the EOs were elucidated based on their retention indices, as well as with reference to literature report. Other portions of the dried leaf, inflorescence and stem bark of each cultivar were extracted with methanol. The methanol extract was profiled for its cannabinoid content using liquid chromatography mass spectrometry (LCMS) based metabolomics approach, with reference to standard cannabinoids (∆9-THC, ∆9-THCA, and CBD). Lastly, the dried stem bark of Cultivar II was investigated for its compounds. The stem bark powder was subjected to sequential extraction at room temperature with n-hexane, dichloromethane, ethyl acetate and methanol. Based on the TLC analysis, the afforded n-hexane and ethyl acetate extracts were further individually fractionated on a repeated column chromatography, using silica gel and Sephadex LH20 as stationary phases. The column fractionation process led to the isolation of seven compounds, E1-E4, A20, A21, and A23. The isolated compounds were characterized by spectroscopic and spectrometric methods on nuclear magnetic resonance (NMR) spectrometer and ultra high-performance liquid chromatography hyphenated to a mass spectrometer, respectively. The results from the study showed that the EOs of the C. sativa cultivars contain majorly sesquiterpenes in their oxygenated and non-oxygenated forms. Caryophyllene (0.6421.4%), caryophyllene oxide (1.27-20.34%), -pinene (0.35-13.21%), D-limonene (0.51-10.99%), humulene (0.37-10.56%), humulene-1,2-epoxide (0.45-5.98%), pinene (0.16-5.22%), nerolidol (0.32-4.99%), -myrcene (0.31-4.23%), -selinene (0.92-2.51%), and trans--bergamotene (0.50-2.70%), were the main terpene constituents of the EOs in both cultivars. Neutral cannabinoids were also detected in both cultivars with cannabidiol found in significant amount up to 85.03% in the fresh stem oil (LSO) of Cultivar I (Lifter). LC-MS fingerprints revealed that Cultivar I had the highest accumulation of cannabinoids with CBDA having the highest amount (88.65%) in the stembark and CBD at about 23% in the leaves. The inflorescence (flower) contained 51.55% of CBDA. Cultivar II had the least number of cannabinoids but contains the highest amount of ∆9-THCA (94.8%) in the leaf sample. Cultivar II showed ∆9-THCA and ∆9-THC dominant profiles with less than 2% of ∆8-THC. ∆9-THC, ∆8- THC were the only neutral cannabinoids detected in Cultivar II while CBD, ∆9-THC, and ∆8- THC were found in significant amounts in Cultivar I. The compounds isolated from the stem bark of Cultivar II were elucidated as five triterpenoids: Sativalenic acid ethyl ester (E1), Phyllanthone (E2), Friedelin (E3), Sativalonone (A20) and Sativaol (A23); an alkaloid, Sativacherine (E4); and a fatty acid ester, Ethyl stearate (A21). Four of these compounds are newly described, while all the compounds are reported for the first time from the Eastern Cape Cultivar (Cherrywine) of C. sativa stem. , Thesis (PHD) -- Faculty of Natural Sciences, 2024

- Description: Cannabis sativa L. (Family Cannabaceae) has continued to attract much interest among natural product scientists in recent time because of its known medicinal values and remarkable chemical diversity. This study reports the investigation of C. sativa cultivated in the Eastern Cape Province of South Africa, with a view to obtaining its chemical fingerprint and isolating compounds from its stem bark for possible biological applications. Fresh and dried leaves, flowers, stem barks and roots of two Cannabis cultivars were obtained under permit NO. PIA-HP-EC-2022-0023. The fresh and dried plant materials were extracted for their essential oils (EOs), using hydro-distillation method on a Clevenger apparatus set at optimum extraction condition. The EOs were characterized by a gas chromatography coupled to a mass spectrometer (GC-MS). The chemical components of the EOs were elucidated based on their retention indices, as well as with reference to literature report. Other portions of the dried leaf, inflorescence and stem bark of each cultivar were extracted with methanol. The methanol extract was profiled for its cannabinoid content using liquid chromatography mass spectrometry (LCMS) based metabolomics approach, with reference to standard cannabinoids (∆9-THC, ∆9-THCA, and CBD). Lastly, the dried stem bark of Cultivar II was investigated for its compounds. The stem bark powder was subjected to sequential extraction at room temperature with n-hexane, dichloromethane, ethyl acetate and methanol. Based on the TLC analysis, the afforded n-hexane and ethyl acetate extracts were further individually fractionated on a repeated column chromatography, using silica gel and Sephadex LH20 as stationary phases. The column fractionation process led to the isolation of seven compounds, E1-E4, A20, A21, and A23. The isolated compounds were characterized by spectroscopic and spectrometric methods on nuclear magnetic resonance (NMR) spectrometer and ultra high-performance liquid chromatography hyphenated to a mass spectrometer, respectively. The results from the study showed that the EOs of the C. sativa cultivars contain majorly sesquiterpenes in their oxygenated and non-oxygenated forms. Caryophyllene (0.6421.4%), caryophyllene oxide (1.27-20.34%), -pinene (0.35-13.21%), D-limonene (0.51-10.99%), humulene (0.37-10.56%), humulene-1,2-epoxide (0.45-5.98%), pinene (0.16-5.22%), nerolidol (0.32-4.99%), -myrcene (0.31-4.23%), -selinene (0.92-2.51%), and trans--bergamotene (0.50-2.70%), were the main terpene constituents of the EOs in both cultivars. Neutral cannabinoids were also detected in both cultivars with cannabidiol found in significant amount up to 85.03% in the fresh stem oil (LSO) of Cultivar I (Lifter). LC-MS fingerprints revealed that Cultivar I had the highest accumulation of cannabinoids with CBDA having the highest amount (88.65%) in the stembark and CBD at about 23% in the leaves. The inflorescence (flower) contained 51.55% of CBDA. Cultivar II had the least number of cannabinoids but contains the highest amount of ∆9-THCA (94.8%) in the leaf sample. Cultivar II showed ∆9-THCA and ∆9-THC dominant profiles with less than 2% of ∆8-THC. ∆9-THC, ∆8- THC were the only neutral cannabinoids detected in Cultivar II while CBD, ∆9-THC, and ∆8- THC were found in significant amounts in Cultivar I.
