- Description: This study was completed as part of a project exploring social inclusion and exclusion in South African higher education. In a globalised world, the achievement of a qualification from an institution of higher education is increasingly key to finding any sort of employment. This is particularly the case in South Africa where employment amongst black citizens is inordinately high. The aim of the research reported upon in this thesis was to better understand the construct of ‘epistemological access’ (Morrow, 1992), often used in relation to the needs of black working class students entering higher education, in relation to performance data (see for example, CHE, 2016) that repeatedly shows that black students fare less well than their white peers. Following what might be termed a ‘social’ approach to understanding access, this study begins long before most students have even heard of higher education and focuses on identifying the mechanisms that come into play at much earlier level of learning and literacy development. The study outlines the development of ‘ways of being’, or social practices, surrounding learning in a marginalised community in Port Elizabeth, in the Eastern Cape, South Africa. This was achieved by means of critical ethnography and it is therefore qualitatively based. The study shows how social structures enable or constrain a child’s school readiness and how they then go on to support or impede progress in school where the language and literacy needed for educational success are further developed. The study therefore aims to allow us to explain global data indicating that the single greatest indicator of a young person’s ability to access and succeed in higher education is the level of education of caregivers in their homes of origin. Examined from a critical perspective (i.e. with a concern for social justice), this study has made use of a framework using social, psychological and linguistic theory and more, particularly, the work of sociologist Margaret Archer (1995, 1996, 2003). The study makes particular use of Archer’s ‘morphogenetic framework’ which allows for an analysis of the way structure and culture impact on a child’s development over time. As I was concerned that my own social status might impact on the understandings I developed as a critical ethnographer, the study acknowledges my own experiences of learning and the way my own family sought to enhance them as enabling. In doing this, the study aims to better contribute to understandings of social justice in South Africa.

- Description: As a developing nation, South Africa faces a high rate of poverty, high levels of inequality in terms of income and a high rate of unemployment. It is officially estimated that about 27.2% of the economically active population are unemployed. SMEs are expected to be an important vehicle to address the challenges of job creation, sustainable economic growth, equitable distribution of income and the overall stimulation of economic development. SMEs in South Africa constitute 99% of all businesses, contributing to employment, income inequality and poverty alleviation (Statistic South Africa, 2018). However, despite the remarkable contribution of SMEs to the economy of South Africa, the failure rate of SMEs (at 75%) is the highest of all the efficiency-driven economies sampled by the Global Entrepreneurship Monitor (GEM). The World Bank affirm that the availability of and access to credit from the formal financial sector is the primary cause of the high failure rate of SMEs. Contemporary literature advance that the future survival and performance of SMEs in South Africa is pegged onto the amount of financial capital available to address their capital needs. Thus, this study sought to analyse the availability of and access to credit from the formal financial sector and the performance of SMEs from the supply and demand-side. In order to achieve the objectives of the study, a sequential exploratory mixed method research design, located in the pragmatic research paradigm, was used in a two phased approach. The qualitative data collection and analysis in Phase 1 informed the quantitative data collection and analysis Phase 2. In Phase 1, in-depth face-to-face semi-structured interviews were conducted with 8 credit and 8 business managers representing the sampling unit of selected formal financial institutions. The qualitative data collected was analysed using the five-steps process of content analysis as illustrated by Terre Blanche et al. (2006:322-326). The main findings with regard to factors that impact on the willingness of the formal financial sector to provide credit to SMEs were collateral, annual business turnover, audited financial records, relationship with the bank, credit profile, nature of the business, economic climate, ethics, nationality, government policy, management team, valid Identity Document/permit, equity contribution, entrepreneurship education, product quality, and business intelligence. Assessing credit applications from SMEs, risk assessment, inspection of financial records, proper documentation and background checks were the different tasks performed by credit and business managers. In addition, the main challenges faced by the formal financial sector in assessing and approving credit in favour of SMEs included the following: lack of investment capital; lack of collateral; lack of proper financial records; poor managerial knowledge; poor business plan; lack of industrial knowledge; and poor legal and credit laws. Lastly, contrary to the notion that formal financial institutions are not interested in investing in SMEs, on average, 70% of SMEs that applied for credit received such credit. In Phase 2, a self-administered questionnaire was used to collect data from formal sector owner/managers of SMEs in the city of Johannesburg. Of the 702 questionnaires distributed, 300 were returned and useable. Data was analysed using the Statistical Package for the Social Sciences (version 24). A test for normality was performed using Shapiro–Wilks test. Reliability was tested using the Cronbach’s Alpha Coefficient. Exploratory factor analysis tested the validity of factors that prevent formal financial sector from granting credit to SMEs while Binary logistic regression was used to infer on the hypotheses. Spearman’s Rho correlation analysis was used to determine whether there was any significant relationship with factors that influence access to credit and SMEs performance. The main findings revealed that access to bank finance was the only challenge that showed a significant correlation with performance. In addition, the study revealed that the South African Identity Document and collateral were the most important factors considered when applying for credit from formal financial institutions. With regard to the reasons why formal financial institutions may refuse to grant credit to SMEs, it was revealed that there was no significant positive relationship between lack of business networking and access to credit from the formal financial sector to SMEs. Conversely, the study also revealed a significant positive relationship between collateral, business information, managerial competency, business intelligence, business ethics, entrepreneurship education, legal system and macro-economy and access to credit from the formal financial sector to SMEs. Thus, it was established that there is a significant positive relationship between access to credit from the formal financial sector and the performance of SMEs.

- Description: Coastal human ecology (CHE) is a mixture of different theoretical and thematic approaches straddling between the humanities and social and natural sciences which studies human and coastal/marine interactions at the local-scale and through intense fieldwork. Topics of interest include human coastal adaptations past and present; the historical ecology of fisheries and future implications; local forms of marine governance and economic systems; local food security and livelihoods, and indigenous/local ecological knowledge systems among many research themes. In this paper, I explore different strands of CHE in the study of tribal, artisanal, and small-scale industrial fisheries from the mid-90s onward that can contribute to the foundational knowledge necessary for designing and implementing successful coastal fisheries management and conservation programs. Marine conservation has often failed due to a lack of understanding of the fine grained marine human-environmental interactions at the local scale. In this context, I also examine developing and future research directions in CHE, and discuss their potential contribution for filling the gap in existing approaches to actionable scholarship in marine conservation. The strength of many CHE approaches lies in their potential for bridging humanism and natural science, and thus CHE approaches are well equipped to address many of the challenges faced by marine conservation practitioners today.

- Description: Coastal communities are some of the most at-risk populations with respect to climate change impacts. It is therefore important to determine the vulnerability of such communities to co-develop viable adaptation options. Global efforts to address this issue include international scientific projects, such as Global Learning for Local Solutions (GULLS), which focuses on five fast warming regions of the southern hemisphere and aims to provide an understanding of the local scale processes influencing community vulnerability that can then be up-scaled to regional, country and global levels. This paper describes the development of a new social and ecological vulnerability framework which integrates exposure, sensitivity and adaptive capacity with the social livelihoods and food security approaches. It also measures community flexibility to understand better the adaptive capacity of different levels of community organization. The translation of the conceptual framework to an implementable method is described and its application in a number of “hotspot” countries, where ocean waters are warming faster than the rest of the world, is presented. Opportunities for cross-cultural comparisons to uncover similarities and differences in vulnerability and adaptation patterns among the study’s coastal communities, which can provide accelerated learning mechanisms to other coastal regions, are highlighted. The social and ecological framework and the associated survey approach allow for future integration of local-level vulnerability data with ecological and oceanographic models.

- Description: Township tourism is regarded as one of the fastest growing tourist activities in Namibia (Buning, Legant, Schauwinhold, Steinbrink & Subenguth, 2016:14). This research study presents an exploratory inquiry that seeks an in-depth understanding of residents’perspectives on township tourism in Mondesa, Swakopmund, Namibia.In order to conceptualise the extent to which the residents’needs are being met through the benefits derived from township tourism. The residents’ perspectives on township tourism in Mondesa areexplored with respect to the benefits and costs derived from township tourism, participation in township tourism, and interaction with tourist during a township tour and consultation on township tourismwhich forms part of the research questions ofthe study. By applying the Social Exchange Theory (SET) in this study, the relationships between the variables that influence the residents perceived benefit and costs of township tourism in Mondesa are explored further in depth in combination with Pretty’s Typology of participation and Scheyne’s typology of community empowerment in tourism (Ap, 1992: 668; Mason, 2003:119; Sharpley and Telfer, 2002:152;Cooper, Fletcher, Gilbert & Wanhill, 1993:91).These variables are namely; social, economic, psychological, environmental, cultural, Manipulative, passive, educational and political factors. They form part of the conceptual framework of the study.This study followed a qualitative research approachandmultiple data sources were collected including semi-structured interviews with residents from Mondesa:these included residents involved in township tourism and those not involved in township tourism. To triangulate the data collection, semi-structured interviews were conducted with representatives from tourism industry and government bodies related to townshiptourism. Data analysis was done through the facilitation of Atlas tiaqualitative data analysis software and deductive codes were established from the literature(variables from the conceptual framework)and themes were developed from the research questions.The findings indicate that residents who are not involved in township tourism arenot influenced by the benefit and cost equation of the social exchange theory (Andriotis, 2005:69). Therefore residents not involved in township tourism are positive about tourism irrespective of whether they benefit directly from financial gain through tourism. The findingsfurtheremphasis oncommunity benefitsfrom township tourism being as important, than individual benefits. This study also provides knowledge that meaningful interaction between tourist and residents has the ability to reduce the apartheid paradigm of racial division and discrimination, which was the basis of the formation of townships.Residents’ misconception about white people are changed due to their personal interaction and cultural exchange with white tourist during a township tour. Anothersignificant findings to emerge from this study is the ability for township tourism to transform the lives of residents living in townships through the intrinsic benefits derived from township tourism. Township tourism has the ability to contribute to positive human exchange through interaction between residents and tourists. By sharing a positive cultural exchange, strong relationships are built between the tourists and residents, which may provide long term sustainability of township tourism. The positive personal transformational effect on residents through interaction with tourists is contributing to residents’ socio-economic well-being. Therefore township tourism has the ability to quantitatively and qualitatively address the alleviationof poverty in townshipsand fostering understanding and mutual respect among peoples of the world.The studyconcluded with a framework of guidelines toaid key stakeholders in the development and planning of township tourism and encourages the practice of sustainable tourism in townships.

- Description: With the changing landscape in South Africa to full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. Given that the Raven’s Coloured Progressive Matrices (CPM) is purported to be culture-free and not heavily dependent on verbal and language skills; it has been extensively normed throughout the world for various population groups. While norms for normal populations of children have been developed in South Africa, these studies were based on race and gender predominantly and without taking into consideration the effects of socio-ecological factors on test performance. The research study aimed to understand the influence of socio-ecological factors on the expression of cognitive scores amongst a geographically diverse sample of South African learners. Through this study, research on the interplay between context and cognition was to be located within the Ecological Systems model of Bronfenbrenner. A secondary aim of the study was to develop an index that will guide test selection and interpretation of assessment results, taking into account the influence of socio-ecological factors and providing a conceptual framework for future test development. The study employed a quantitative methodology on a South African sample consisting of primary school children aged between the ages of 6 years to 11 years. The sample was drawn from schools in the Port Elizabeth area in South Africa that were classified into low, medium, and high opportunity, based on context. The results indicated that the type of school had a significant impact on test performance, suggesting that contextual factors were influential in this process. The item analysis conducted further indicated that learners from a low opportunity school performed significantly lower than the other two schools in the sample. The index development provides a foundation for further research that would enhance the interpretation of test results. In the South African context, this is considered important, given our political history and our diversity where a “one size fits all” approach is not possible.

- Description: With the changing landscape in South Africa to full democracy, increased research has been undertaken in the psychometric field on local and national normative studies regarding various assessment measures. Given that the Raven’s Coloured Progressive Matrices (CPM) is purported to be culture-free and not heavily dependent on verbal and language skills; it has been extensively normed throughout the world for various population groups. While norms for normal populations of children have been developed in South Africa, these studies were based on race and gender predominantly and without taking into consideration the effects of socio-ecological factors on test performance. The research study aimed to understand the influence of socio-ecological factors on the expression of cognitive scores amongst a geographically diverse sample of South African learners. Through this study, research on the interplay between context and cognition was to be located within the Ecological Systems model of Bronfenbrenner. A secondary aim of the study was to develop an index that will guide test selection and interpretation of assessment results, taking into account the influence of socio-ecological factors and providing a conceptual framework for future test development. The study employed a quantitative methodology on a South African sample consisting of primary school children aged between the ages of 6 years to 11 years. The sample was drawn from schools in the Port Elizabeth area in South Africa that were classified into low, medium, and high opportunity, based on context. The results indicated that the type of school had a significant impact on test performance, suggesting that contextual factors were influential in this process. The item analysis conducted further indicated that learners from a low opportunity school performed significantly lower than the other two schools in the sample. The index development provides a foundation for further research that would enhance the interpretation of test results. In the South African context, this is considered important, given our political history and our diversity where a “one size fits all” approach is not possible.

- Description: The biosynthesis of silver nanoparticles (Ag-NPs) using the hydrosol extract of the dry stem bark of Acacia mearnsii as reducing and capping agents, and their antinociceptive properties are hereby reported. By varying the temperature and reaction time, the temporal evolution of the optical and morphological properties of the as-synthesized material was investigated. The NPs were characterized by UV–visible absorption spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS) and x-ray diffractometry (XRD) The optical analyses show that the position of the maximum surface plasmon resonance (SPR) peak is red-shifted as the reaction temperature decreased. The TEM micrographs show that the as-synthesized Ag-NPs are spherical while the X-ray diffraction shows that the material is highly crystalline with face-centered cubic structures. The anti-inflammatory efficacy, analyzed by the formalin model, indicates that the as-synthesized Ag-NPs are very effective, with an inhibition rate of about 76%.

- Description: A wide range of research locally points to intermediate phase learners having extremely weak basic number sense resulting in the dominance of inefficient strategies for calculations with the four operations, irrespective of the number range. The grade six Annual National Assessments (ANA) diagnostic reports for 2012 to 2014 also point to errors and misconceptions that tend to dominate learners’ computations in the four basic operations; such errors are often attributed to the use of either tallies or incorrectly applied mathematical procedures. Having the above context in mind and following informal conversations with teachers in the Uitenhage Education District, five teachers expressed an interest in running the afterschool mathematics clubs based on the South African Numeracy Chair (SANC) project model. The SANC project team ran workshops in April, May and June 2016 with nine teachers (five as facilitators and four others as co-facilitators in five different club sites) in which teachers were provided with key resources for use in their clubs. Fifteen club sessions ran in each club with grade six learners across the 2nd and 3rd terms. These clubs form the empirical field for this research, which aims to investigate the nature of learners’ evolving number sense, procedural fluency and teachers’ experiences of working with learners in the club space. The unit of analysis in this study is both the shifts evident in learners’ number sense and procedural fluency as a result of participating in the clubs and the teacher’s experiences of working with learners in those clubs as club facilitators. A social constructivist perspective of learning guides this study. Especially Vygotsky’s (1978) notion that cognitive development stems from social interactions and guided learning within the Zone of Proximal Development (ZPD) of children, guided by more knowledgeable others. Furthermore, Kilpatrick et al.’s (2001) strands of mathematical proficiency provide the conceptual frame with a particular focus on procedural fluency and number sense. A mixed method approach to data collection was used. Quantitative data has been drawn from learner’s scores on pre- and post- assessments on four basic operations. Visual progression spectra have been adopted from the Pushing for Progression (PfP) Programme which is an intervention Programme developed by the SANC project for club facilitators. They provide explanations of learner progression trajectories and how to analyse learner methods. Qualitative narratives were drawn from learner progression data, as well as teacher post club questionnaires and one-to-one teacher interviews. The findings of this research suggest that learner workings when used in conjunction with visual progression spectra can provide important clues to researchers and teachers. This in turn contributes to an understanding of where learners are in their mathematical learning and gives ideas for how to support learners to progress using more flexible methods of calculation, particularly for poor performing learners. Included, is the discussion of the effectiveness of the club space to enable such shifts and improve learner flexibility, fluency and performance as displayed in learner methods and scores of the pre- and post- assessments. The teachers’ observations about the relaxed atmosphere in the club space, small sized groups, learning through play with co-members may have enabled the shifts in procedural fluency and number sense in club learners. Additionally, implications of the study are discussed, and tentative recommendations are made for the DBE to consider.

- Description: Sn(IV) porphyrins ([Sn(IV)TTP(3PyO)2] (5) and [Sn(IV)TPP(3PyO)2] (6) [tetrathienylporphyrin (TTP), tetraphenylporphyrin (TPP), and pyridyloxy (PyO)]) were prepared and characterized and their photocytotoxicity upon irradiation with 625 nm light has been studied. The presence of the 3PyO axial ligands was found to limit the aggregation and enhance the solubility of 5 and 6 in DMF/H2O (1 : 1). The photophysical properties and photodynamic therapy (PDT) activity of the meso-2-thienyl and meso-phenyl-substituted Sn(IV) porphyrins are compared. 5 and 6 were found to be photocytotoxic in MCF-7 cancer cells when irradiated with a Thorlabs M625L3 LED at 625 nm but remained nontoxic in the dark. The PDT activity of Sn(IV) meso-tetra-2-thienylporphyrin 5 was found to be significantly enhanced relative to its analogous tetraphenylporphyrin 6. There is a marked red-shift of the Q00 band of 5 into the therapeutic window due to the meso-2-thienyl rings, and 5 has an unusually high singlet oxygen quantum yield value of 0.83 in DMF. The results demonstrate that readily synthesized axially ligated Sn(IV) meso-arylporphyrins are potentially suitable for use as singlet oxygen photosensitizers in biomedical applications and merit further in depth investigation in this context.

- Description: Two Sn(IV) triarylcorroles were synthesised and characterized. The absorption spectrum of a meso-thien-2-yl substituted tin(IV)corrole (1-Sn) is red shifted compared to its phenyl analogue (2-Sn) and shows no sign of aggregation in solution. 1-Sn and 2-Sn exhibited singlet oxygen quantum yields of 0.87 and 0.54 in DMF, and have a triplet lifetime of 31 and 50 μs, respectively. Time dependent cellular uptake in MCF-7 cells for 1-Sn reached a peak at 24 h, and 1-Sn was found to be more lipophilic than 2-Sn. 1-Sn showed good photo-cytotoxicity on exposure to a Thorlabs 625 nm LED with an IC50 value of 3.2 μM and remained inactive in the dark.

- Description: The effectiveness of using a teaching strategy, based on analogies for direct current electric circuits, to attempt to address first-year underprepared university students was investigated. The study consisted of 53 participants drawn from the Faculty of Health Sciences at Nelson Mandela University. A quantitative research design was adopted using the “Determining and Interpreting Resistive Electric Circuits Concepts Test” (DIRECT) version 1.2 as a research instrument. The DIRECT is a 29-item multiple-choice test with only one correct answer in each question. The DIRECT was modified to further probe students’ confidence levels in their answers. The instrument served as a pre-test prior to the start of the formal lessons on direct current electric circuits. At the end of a five-week treatment period, the same instrument was administered to all participants as a post-test. The statistical analysis and interpretation of the preand post-test data were conducted using Software Package for Social Sciences (SPSS) version 23 and STATISTICA version 12. In answering the main research question (How can a misconception-based module, using analogies,positively influence(or not)academically under-prepared first-year non-major Physics students’ conceptual understanding of direct current(DC)electricalcircuits?)and sub-questions thereof, the students’ mean scores between the pre-and posttest were calculate and compared using t-test at a significant level of 0.05. The results revealed a statistically significant difference between the preand post-test mean scores. The pre-test mean score was 22.24 with a standard deviation of 8.07. The post-test mean score was 38.68 with a standard deviation of 13.93. The mean score difference between the post-test and pre-test was 16.44 with a standard deviation of 13.82 at p-value less than 0.05. The results from the pre-test suggest that students held very strong alternative conceptions on direct current electric circuits. The post-test results also revealed that some alternative conceptions were still held onto after the intervention. There wasno statistical significant difference found between the students’ correct answers and their confidence levels. The quantitative analysis of the results suggested that there is a positive change between the post-testmean score and pre-test mean score and this change is statistically significant (p < 0.05). The results showed sufficient evidence to conclude that analogies-based teaching strategy was a vieffective means of reducing the number of alternative conceptions the students held about direct current electric circuits. The study recommended the need to ascertain out what the students felt about the improvement of their understanding of direct current electric circuits concepts. The study suggested a qualitative research methodology as an area for future research.

- Description: Globally, there is a downward trend in youths’ political interest and participation in the learning of political education in their school curricula as a measure to combat the apparent dangers posed by the declining young citizens’ participation in the political processes.This study therefore investigated political education as a determinant of university students’ political participation in the Province of the Eastern Cape, South Africa. The study employed a mixed methods design. Using the probability sampling technique, a sample of 375 participants was randomly selected from one university in the Eastern Cape Province while semi-structured interviews were conducted among five (5) purposively selected members of the same university’s Student Representative Council (SRC) executive committee. Simple descriptive statistics such as frequency counts and percentages were used to summarize all categories of variables; while Pearson correlation statistics, Chi-square and Ordinary least square regression were used to examine the relationship between dependent and independent variables at a 95percent confidence interval. Alpha values less than 0.05 were considered to be statistically significant. Thematic content analysis was performed on the qualitative data. The quantitative analysis revealed that students’ level of political awareness was high; 98.1percent of them were aware of their rights to vote and be voted for. Students’ political judgment was positively correlated with participation in campus (r =0.182) and national politics (r = 0.030) respectively. Most of the students agreed to take part in the 2018 SRC (78.8percent) and 2019 national elections (77.9percent) respectively. Political interest was significantly correlated with participation in campus (r = 0.375) and national politics (r =0. 404). The findings from the multivariate analysis showed that political interest (<0.001), parents’ political involvement (<0.001) and year of study (<0.001) were the significant determinants of students’ participation in politics. The qualitative findings also showed that there was a positive relationship between political education and students’ participation in politics. Since political interest and family are element and agent of political education respectively, it is concluded that political education is to a large extent a determinant of university students’ political participation. It is recommended that the universities, the Department of Higher Education and Training (DHET) and other stakeholders should do a thorough review of the university education curricula and programmes to ensure that political education is adequately accommodated and taken care of in a way that would increase students’ interest, awareness and participation in politics. When this is amply done, students’ cognitive skills and capacities would be enhanced to increase their participation in the political processes in South Africa.

- Description: Artificial light may be altering the interactions between bats and moth prey. Unable to make use of bat evasion strategies around artificial light, eared moths are susceptible to exploitation by syntonic bats (using echolocation frequencies between 20-50 kHz within the hearing range of eared moths). Using a handheld plasma metabolite analyzer, I evaluated the foraging success of syntonic bats and rarer allotonic bats (using echolocation frequencies outside the hearing range of eared moths), in areas with artificial light and in areas of natural darkness. I used microscope diet analysis to determine whether bats were consuming more or fewer moths in areas with artificial light and in areas of natural darkness. Syntonic bats were more selective for moth prey under lit conditions, likely owing to a reduction in the ability of tympanate moths to evade bats. Moths increased in the diets of generalist syntonic bats (Pipistrellus hesperidus) foraging around artificial light sources. Some P. hesperidus individuals showed high β-hydroxybutyrate levels around lights, but there was no difference in β-hydroxybutyrate levels between lit and unlit conditions. There is insufficient evidence to reject the null hypothesis that the foraging success of syntonic bats is equivalent in lit vs unlit conditions. The foraging success and diets of allotonic bats, Rhinolophus capensis, appear to be negligibly impacted by artificial light on a small scale. My study emphasizes the need for a mechanistic understanding of the influence of artificial light on the foraging success of bat species. Bat-moth interactions may be influenced by other factors apart from the common assumption that increased refuelling rates will occur in syntonic species foraging on moths around artificial light.

- Description: Artificial light may be altering the interactions between bats and moth prey. Unable to make use of bat evasion strategies around artificial light, eared moths are susceptible to exploitation by syntonic bats (using echolocation frequencies between 20-50 kHz within the hearing range of eared moths). Using a handheld plasma metabolite analyzer, I evaluated the foraging success of syntonic bats and rarer allotonic bats (using echolocation frequencies outside the hearing range of eared moths), in areas with artificial light and in areas of natural darkness. I used microscope diet analysis to determine whether bats were consuming more or fewer moths in areas with artificial light and in areas of natural darkness. Syntonic bats were more selective for moth prey under lit conditions, likely owing to a reduction in the ability of tympanate moths to evade bats. Moths increased in the diets of generalist syntonic bats (Pipistrellus hesperidus) foraging around artificial light sources. Some P. hesperidus individuals showed high β-hydroxybutyrate levels around lights, but there was no difference in β-hydroxybutyrate levels between lit and unlit conditions. There is insufficient evidence to reject the null hypothesis that the foraging success of syntonic bats is equivalent in lit vs unlit conditions. The foraging success and diets of allotonic bats, Rhinolophus capensis, appear to be negligibly impacted by artificial light on a small scale. My study emphasizes the need for a mechanistic understanding of the influence of artificial light on the foraging success of bat species.

- Description: Artificial lights may be altering interactions between bats and moth prey. According to the allotonic frequency hypothesis (AFH), eared moths are generally unavailable as prey for syntonic bats (i.e., bats that use echolocation frequencies between 20 and 50 kHz within the hearing range of eared moths) due to the moths’ ability to detect syntonic bat echolocation. Syntonic bats therefore feed mainly on beetles, flies, true bugs, and non-eared moths. The AFH is expected to be violated around lights where eared moths are susceptible to exploitation by syntonic bats because moths’ evasive strategies become less effective. The hypothesis has been tested to date almost exclusively in areas with permanent lighting, where the effects of lights on bat diets are confounded with other aspects of human habitat alteration. We undertook diet analysis in areas with short-term, localized artificial lighting to isolate the effects of artificial lighting and determine if syntonic and allotonic bats (i.e., bats that use echolocation frequencies outside the hearing range of eared moths) consumed more moths under conditions of artificial lights than in natural darkness.

- Description: In 2007, a former South African Defence Force (SADF) paratrooper, Marius van Niekerk, embarked on a journey to confront his shameful memories relating to his role in the Angolan Civil War. From Sweden (where he had gone into exile), Van Niekerk returned to Angola, where he had been deployed during the mid-1980s, and recruited three other veterans of the war to join his party: Patrick Johannes, who had been coerced to fight for the Popular Armed Forces for the Liberation of Angola (FAPLA); Samuel Machado Amaru, who was forcefully enlisted by the National Union for the Total Independence of Angola (UNITA); and Mario Mahonga, who had fought for the Portuguese colonial army before he was recruited by the SADF to fight against the Popular Movement for the Liberation of Angola (MPLA) regime. Van Niekerk had been conscripted at the age of seventeen, and the others had been coerced into their respective militias at more tender ages. It is not clear how the three Angolans were induced to participate in the project, whose objectives they evidently did not share.

- Description: This dissertation discusses the involvement of a community in creating development opportunities for youth in Indwe, under Emalahleni Local Municipality in the Eastern Cape. Establishing a position where community members put themselves concerning youth development is what inspired the study. The study is further motivated by trying to gain perspectives from the youth because most discourses on youth rarely feature their voices. Additionally, it seeks to gain perspectives on the stakeholder’s insights on the involvement of the community in youth development. The literature consulted was broken up into; the situation of youth in South Africa, which looked at youth unemployment and youth development policies; youth development, which looked at risk and protective factors that affect youth development. The literature further uncovered the role currently played by communities in youth development, and lastly the multi-stakeholder processes for youth development. The Quintuple Helix model was a framework used to shape this study. This framework emphasises that the natural environment and in this case, the community be added to other stakeholders to ensure a sustainable youth development. What is crucial in the framework is the overlap and cross-communication between the different helixes or sectors, sectors such as the university, the government, the private sector, the culture based media, and the natural environment. The study utilised a qualitative methodology with an interpretive and descriptive paradigm, which used focus groups and a qualitative questionnaire as a method of data collection. The data was analysed and presented following the following three themes; i.e., community involvement in youth development, indigenous knowledge for youth development, and opportunities for youth development. The findings of the study revealed that, if Indwe community provides youth with more spaces, and chances to participate in their development, the youth could challenge prominent discourses than treat them as unmotivated, and exclude them from decision-making processes, which directly affect them, and the society within which they live. The findings also revealed that the Indwe community should inform youth iv development programmes, as this would ensure sustainability, and give a sense of ownership to the community. The findings further indicated that the Indwe community could utilise its natural resources to create opportunities for youth development. Moreover, the private sector, the media, and the education system have all contributed in youth development; however, the government has taken full responsibility for youth development in Indwe, and this caused the participants to feel that it is the government’s responsibility to create opportunities for youth development. In conclusion, Indwe community has a challenge of youth development. The problem is fuelled by issues such as complexity in politics, nepotism, and a lack of opportunities. Stakeholders such as the private sector, the media based culture, and the government are involved in the creation of development opportunities for youth in Indwe. However, the sector that has taken the most responsibility for the development of youth is the government. Indwe community members are not involved in the creation of opportunities for youth development; they, however, understand that they have to be significant role players.

- Description: After the 1994 general elections, the government realised the importance of efficient and effective financial management and public sector procurement for the rebuilding of South Africa. This was done by embarking on a major review of its financial and supply chain management systems. The financial and supply chain management systems operate in an ever-changing environment, and that requires that these systems are fit for purpose. Supply Chain Management is one of the cornerstones for the performance of any organisation or company. Section 217 (3) of the Constitution of the Republic of South Africa requires organs of state irrespective of whether they are at National, Provincial or Local government level to apply a procurement system which is fair, equitable, transparent, competitive and cost-effective when contracting for goods and services. The Constitution also attempts to protect and advance persons disadvantaged by unfair discrimination. Supply Chain Management has met an ever-increasing interest over the past decade. This interest comes from within the industry due to the huge amounts involved in procurement and the supply chain value creation. Every society strives to be in a state where every need is available and every citizen has what he/she requires to be able to leave a fulfilled life. In order to meet the needs of societies, member of the society carry out economic activities. The public procurement practice and systems have been acclaimed, based on empirical evidence, as the best means of guaranteeing the provision of public goods to the Citizens and public expenditure management.

- Description: This dissertation investigates listeners’ participation in community radio, drawing on Forte FM radio in Nkonkobe Municipality in Alice, Eastern Cape. The aim of the study was therefore to explore how listeners are been involved in the activities of Forte FM radio station. This study adopts qualitative research approach. Convenience, and purposive non-probability samplings techniques were subsequently used to select samples for this study. In-depth interviews was conducted with the radio station manager while one focus group discussion each was held with residents of Golf Course and Ntselamanzi areas with eight participants in each focus group, making a total number of sixteen participants for the focus group discussions. The collected data were interpreted and analyzed thematically. The findings of this research showed a remarkable disparity between the listeners of the radio station and perceptions of participation on one hand, and the listeners’ opinion and perceptions of them vice versa. Also, programming is often conceptualized with little or no community involvement and interaction. Listeners interviewed in the course of carrying out the focus group discussion in the two sampled areas were of the views that they only get connected to Forte FM radio station on social grounds of greetings and “shout outs”, through public spheres and for self-representation in the variety of public spaces of Forte FM radio. Another critical finding of this study indicated that, Forte FM is doing its best towards involving listeners in its programming.

- Description: Crowdsensing aims to empower a large group of individuals to collect large amounts of data using their mobile devices, with the goal of sharing the collected data. Existing crowdsensing studies do not consider all the activities and methods of the crowdsensing process and the key success factors related to the process. Nor do they investigate the profile and behaviour of potential participants. The aim of this study was to design a crowdsensing method for water resource monitoring in smart communities. This study opted for an exploratory study using the Engaged Scholarship approach, which allows the study of complex real-world problems based on the different perspectives of key stakeholders. The proposed Crowdsensing Method considers the social, technical and programme design components. The study proposes a programme design for the Crowdsensing Methodwhich is crowdsensing ReferenceFrameworkthat includes Crowdsensing Processwith key success factors and guidelines that should be considered in each phase of the process. The method also uses the Theory of Planned Behaviour (TPB) to investigate citizens’intention to participate in crowdsensing for water resource monitoring and explores their attitudes, norms and perceived behavioural control on these intentions. Understanding the profiles of potential participants can assist with designing crowdsensing systems with appropriate incentive mechanisms to achieve adequate user participation and good service quality. A survey was conducted to validate the theoretical TB model in a real-world context. Regression and correlation analyses demonstrated that the attitudes, norms and perceived behavioural control can be used to predict participants’ intention to participate in crowdsensing for water resource monitoring. The survey results assisted with the development of an Incentive Mechanism as part of the Crowdsensing Method. This mechanism incorporates recruitment and incentive policies, as well as guidelines derived from the literature review and extant system analysis. The policies, called the OverSensepolicies, provide guidance for recruitment and rewarding of participants using the popular Stackelberg technique. The policies were evaluated using simulation experiments with a data set provided by the case study, the Nelson Mandela Bay Municipality. The results of the simulation experiments illustrated that the OverSenserecruitmentpolicycan reduce the computing resources required for the recruitment of participants and that the recruitment policy performs better than random or naïve recruitment policies. The proposed Crowdsensing Method was evaluated using an ecosystem of success factors for mobile-based interventions identified in the literature and the Crowdsensing Method adhered to a majority (90%) of the success factors. This study also contributes information systems design theory by proposing several sets of guidelines for crowdsensing projects and the development of crowdsensing systems. This study fulfils an identified need to study the applicability of crowdsensing for water resource monitoring and explores how a crowdsensing method can create a smart community.
