- Description: South African riparian zones have been heavily degraded through anthropogenic activities such as dam construction and extraction of water for irrigation, which has resulted in a loss of ecosystem services and functioning. A consequence of such disturbances to riparian areas is in their susceptibility to invasive alien species (IAS). One such IAS is the giant reed, Arundo donax L. (Poaceae), introduced to South Africa in the 1700s largely for erosion control. Arundo donax has since greatly expanded in the country and is now one of the most abundant IAS. Arundo donax has been found to displace native vegetation and in South Africa this will most likely lead to the displacement of the native tall-statured grasses, Phragmites australis (Cav.) Trin. ex Steud. and Phragmites mauritianus Kunth. This study aimed to enhance our understanding of the tall-statured grasses A. donax, P. australis and P. mauritianus to better manage them in riparian areas. For A. donax, biological control is seen as the most viable option to control stands in the long-term. However, before such a programme is put in place, it is important to first collect baseline data that can be used to guide the direction of the biological control project in South Africa. For the Phragmites spp., despite being a dominant vegetative type in riparian areas, very little is known about their status in South Africa. Furthermore, there have been increasing reports of both Phragmites species having an expansion of their range and abundance. In North America, there has been a similar trend of reed expansion and through molecular work it was determined that a cryptic invasion has occurred with the introduction of an invasive non-native haplotype from Europe. It is therefore unknown if Phragmites spp. populations are expanding due to anthropogenic activities or due to a cryptic invasion. To address these shortfalls in knowledge the study investigated the tall-statured grasses in two parts; firstly, molecular techniques are used to explore the plant origin and genetic diversity of A. donax, P. australis and P. mauritianus and secondly using the Enemy Release Hypothesis as a framework, herbivore assemblages for each reed was determined across their distribution in South Africa. Molecular-techniques determined that both P. australis and P. mauritianus had only one haplotype - known as haplotype K and haplotype V respectively, across their distribution. For P. australis, haplotype K shares a close connection with populations from a Mediterranean lineage and this was further confirmed with a shared grass-waxy band. The direction and timing of genetic exchange between the two regions could not be ascertained and thus still remains unknown. Microsatellite analysis determined that both Phragmites spp. had a high genetic diversity compared to worldwide lineages. With no evidence of any cryptic invasions of haplotypes from other regions, both Phragmites spp. populations are likely to be native to South Africa. For A. donax all populations across South Africa were determined to be haplotype M1; a cosmopolitan haplotype that has an ancient native range in Afghanistan and Pakistan (Indus Valley). Populations were found to have no genetic diversity and thus can be considered one clone. A pre-introductory survey determined a list of herbivores associated with each tall- statured grass. For A. donax, a total of seven herbivores were found. Of these, one herbivore, a galling wasp, Tetramesa romana Walker (Hymenoptera: Eurytomidae) was found to be highly abundant and widely distributed in South Africa. Tetramesa romana is already a biological control agent in North America and thus is likely exerting some pressure on A. donax populations in South Africa. For both Phragmites spp. a total of ten herbivores were found, although having higher species richness compared to A. donax, when compared to other regions, these native species have a relatively low species richness. Providing baseline data on plant origin, genetic diversity and herbivory on A. donax, P. australis and P. mauritianus has provided important information on managing these species in riparian ecosystems in South Africa. For the Phragmites spp. with no evidence of any cryptic invasions, it is recommended that reed stands continue to be managed as native species. Phragmites spp. are important dominant vegetative species and thus should be protected; however, if reed stands become expansive, control methods can be put in place to focus on managing spread and abundance. For A. donax, this study was able to provide pivotal information in guiding the biological control programme. By determining the ancient lineage of South African populations, research can be focused in this area to find potential biological control agents. Lastly, the pre-introductory survey determined that a biological control agent, T. romana was already established with an unknown introduction and also highlighted potential plant parts that should be targeted. In particular, no rhizome feeding herbivores were found in South Africa and therefore this highlights an important niche that should be explored in biological control agents.

- Description: This study sought to explore teachers’ perceptions and experiences of using easily accessible materials and how they might collaboratively develop learning and teaching support materials using easily accessible materials. The study explored three aspects. Firstly, the views, experiences and factors which influence grade 10 Physical Science teachers’ perceptions and experiences of teaching the topic of electromagnetism. Secondly, to find out what teachers can do to improve teaching and learning of electromagnetism in grade 10 Physical Science using easily accessible materials. Thirdly, to look at what enables or constrains grade 10 Physical Science teachers in under-resourced schools when dealing with electromagnetism, from using easily accessible materials. A qualitative method approach was adopted, underpinned by an interpretive paradigm but using some quantitative methods as well. Within the interpretive paradigm a case study approach was used. The study was carried out in Swakopmund and Gobabis education circuits of the Erongo and Omaheke Regions respectively. Data were collected using questionnaires, lesson observations and stimulated-recall interviews. The data obtained were validated in two ways, firstly, by triangulation from different data gathering techniques, and secondly, validation was done by member checking of the transcripts. To make meaning from the data generated, Vygotsky’s (1978) socio-cultural theory was used as a lens to analyse the data. The quantitative data generated were presented in figures, tables; whereas the qualitative data were coded inductively into descriptive texts to make meaning. It was found that teachers’s perceptions and experiences are that the topic of electromagnetism is quite challenging. Teachers reported that their learners find it difficult to comprehend phenomena associated with electromagnetism, thus making it difficult for their learners to grasp concepts associated with it. Lack of resources to do practical activities in the topic of electromagnetism was found to be a major contributing factor to teaching and learning of this topic. The use of easily accessible materials among teachers was found to be very limited. Easily accessible locally sourced materials were found to have the potential to enable grade 10 Physical Science teachers to help learners to make sense of concepts of electromagnetism in under-resourced schools. In light of the above findings, the study recommends that science teachers should make use of easily accessible materials which can minimise their dependence on standard laboratory equipment which is unaffordable anyway by most schools.

- Description: Argumentative writing in Namibian schools has been a challenge over the years as Grade 11-12 English Second Language (ESL) learners perform poorly when compared to other writing that is stipulated in the curriculum. In most instances learners do not satisfy the structural and rhetorical features of this genre. English teachers are, therefore, expected to ensure that argumentative writing is adequately developed in order for the learners’ writing to be up to the required standard. Studies carried out in Namibia by Nghikembua (2013) and Nyathi (2009) indicated that learners perform poorly in writing. The examiners’ reports of 2011-2014 pointed to lack of teachers’ guidance as one of the factors contributing to poor performance. It was for this reason that this study aimed to investigate teachers’ pedagogic approaches when teaching argumentative essay both on Higher and Ordinary Level in Oshikoto region, Namibia. An interpretive qualitative case study was used in order to gain an in-depth understanding of the teachers’ pedagogic approaches and how it affects their learners’ argumentative essay writing. The theoretical framework was informed by the Genre theorist, Gibbons (2002), who focuses on the Curriculum Cycle and Hyland’s (1990) model. Two Grade 11 English teachers were purposefully and conveniently sampled. One of the teachers is from a government school while the other from a private school. Data were collected from interviews, videoed writing lessons (3 per teacher), and learners’ written essays. Data analysis revealed that both teachers have a sound understanding about argumentative writing, but their classroom practices did not sufficiently assist the learners to grasp the argumentative writing conventions. Their classroom practices were not adaptive enough when giving feedback to the learners, and they did not adhere to the four steps of Gibbons’ (2002) Curriculum Cycle. Also, the process to writing (brainstorming, drafting, and revising) was also not incorporated into their teaching. These meant that the Namibian curriculum specifications are not met which deprives the learners of the needed practice scaffolding and explicit teaching into competent independent writers. A recommendation of this study is that there is a need for the teachers to be exposed to a mixed process/genre approach as advocated by the Namibian curriculum.

- Description: The Helicoverpa armigera stunt virus (HaSV), belonging to the Family Alphatetraviridae (Genus: Omegatetravirus), is a non-enveloped insect virus encapsidating a bi-partite, positive-sense single-stranded RNA genome. RNA1 encodes the replicase, as well as three small open reading frames (ORFs) arranged in tandem, and overlapping with the 3’ end of the replicase ORF. These ORFs, designated p11, p15 and p8, encode putative proteins of unknown function. The p11 and p15 ORFs are conserved in the genome of the related Omegatetravirus, Dendrolimus punctatus tetravirus. In HaSV, the stop codon of p11 is followed immediately by the start of p15, whereas the stop of p15 and start of p8 are separated by a glycine intercodon. Furthermore, only p11 is known to have a recognizable Kozak sequence. The aim of this study was to determine the expression and function of these three small proteins in the HaSV infectious lifecycle. The authenticity of the viral cDNA sequence, encoding the three small ORFs, was validated by sequencing multiple cDNA clones of the relevant region in viral RNA (vRNA), purified from infectious HaSV particles. The sequence of all three ORFs was conserved in seven cDNA clones, while point mutations were observed in each of two remaining cDNA clones, suggesting that the ORFs were conserved in infectious virus. Polyclonal antisera were raised against a p11 peptide, and a recombinant p15-p8 fusion protein (p23) expressed and purified from Escherichia coli. The affinity of the anti-p23 antiserum was confirmed by western blot analysis, while that of the anti-p11 antiserum was confirmed using immunofluorescence microscopy, as attempted expression of recombinant p11 in E. coli appeared to be toxic. The antisera were used to detect expression of the small proteins in HaSV-infected H. armigera larvae by western blot analysis. A band migrating at approximately 34 kDa was detected by both antisera in infected larvae, absent in uninfected larvae, suggesting the expression of a p11-p15-p8 polyprotein. Protein bands of 11 kDa and 8 kDa were also detected by the anti-p11 and anti-p23 antisera, respectively. Bioinformatic analysis revealed that the polyprotein would be produced by a novel type of stop codon read-through, however the mechanism required for individual expression could not be definitively determined. The mechanism by which these ORFs are translated was further investigated by expressing p11-p15, tagged with FLAG and enhanced green flourescent protein (EGFP) at its amino- and carboxyl-termini respectively (FLAG-p11-p15-EGFP), in Spodoptera frugiperda (Sf9) cells detected by flourescence microscopy. Punctate structures were observed throughout the cytoplasm that were also detected with antiFLAG, anti-p11 and anti-p23 antisera, complementing results obtained in previous studies. Since p15 does not exhibit a strong recognizable Kozak like p11, the dependency of p15 expression on that of p11 was investigated by mutating this construct such that p15 occurred in a +1 frame to p11. Both EGFP and anti-p23 fluorescence was detected with the same cytoplasmic distribution as the unmutated construct, whereas nothing was detected by anti-FLAG and anti-p11. Preliminary results therefore suggested p15 may also be expressed as a discrete protein, independent of p11. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2018

- Description: Visual literacy is one of the critical aspects that English First Additional Language teachers and learners battle with. The focus of this investigation was on developing learners’ performance in visual literacy and helping teachers improve teaching practice. This thesis reports on efforts in developing critical visual literacy in two Grade 9 classrooms; a rural and a township school in the King William’s Town District in the Eastern Cape. The research spread over four week, spending two weeks at each school as an ethnographic researcher, being assimilated to the culture of the each school. In understanding the kind of visual knowledge that these learners brought from home between the rural-urban divide, the learners displayed an interest in visual literacy, used the necessary language and appeared to design certain visual materials around the school. Data was collected in the form of questionnaires that learners filled, informal Facebook conversation screenshots, as well as the researcher’s field notes. Learner focus group discussions were conducted, tape recorded and transcribed. Two lessons each were observed with the two teachers, and these were recorded and transcribed. A camera was used to take shots in the classroom to show the interaction between the teachers and the learners. Also, semi-structured interviews were held with each teacher and these were recorded and transcribed. The data revealed that there were no major differences between rural and urban school learners. However, the research has provided a valuable insight into the mismatch between home visual literacy practices and school visual literacy teaching. The learners’ digital visual literacy practices were far ahead than those of the teachers who are not able to capitalise on these visual skills; the cultural capital that learners bring to school. Learners also displayed a low reading culture but the medium for reading has shifted considerably and learners developed communication skills through digital technology. Teacher agency in the classroom revealed that teachers need to first engage with the cognitive functions of the visual images that they teach by the prevalence of low level questions that they ask. Moreover, there is a place for translanguaging in visual literacy lessons. These indicate important areas for teacher development to promote the emergence of transformative agency.

- Description: Both my teaching experience and literature of this research study strongly suggested that fractions are difficult to teach and learn across the globe generally, and Namibia in particular. One of the identified contributing factors was teaching fractions by focusing on procedures and not the conceptual understanding. Therefore, this research project developed and implemented an intervention in order to experiment and suggest an alternative teaching approach of fractions using models. The purpose of this research was to: “Investigate the use of models to develop Grade 8 learners’ conceptual understanding of and procedural fluency with fractions”. This investigation had three areas of focus. Firstly, the study investigated the nature of learners’ conceptual understanding of and procedural fluency with fractions before the teaching intervention, by means of administering a pre-test and pre-interview and analysing learners’ responses. Secondly, the study investigated the changes in learners’ conceptual understanding of and procedural fluency with fractions after the teaching intervention, by means of administering a post-test, post-interviews and recall interviews, and analysing learners’ responses. Thirdly, this study investigated the possible influence of the teaching intervention on the changes in learners’ conceptual understanding of and procedural fluency with fractions by analysing the lesson videos and learners’ worksheets, and describe their critical interaction. This study was conducted at a multicultural urban secondary school located in the Oshikoto Region, Namibia. The sample consisted of 12 Grade 8 mathematics learners whose age ranged from 13-16 years old. A purposive sampling method was employed to select both the research site and participants. This research is framed as a case study, and is grounded within the interpretive paradigm and qualitative research. This research revealed that these learners displayed conceptual and procedural difficulties in their engagement with fraction models and fraction symbols, before the teaching intervention. Conceptually, the study found that these learners read fractions using inappropriate names; and learners did not identify the whole unit in the models and therefore identified fractions represented by the fraction models using different forms of inappropriate fraction symbols. Procedurally, the study found that these learners compared and ordered fractions inappropriately using the sizes of the numerators and denominators separately; and learners used the lowest common denominator method inappropriately for adding fractions with different denominators. The research also suggested conceptual and procedural changes in learners’ conceptual understanding of and procedural fluency with fractions and that the intervention seemed to help learners to engage better with fraction models and fraction symbols. Conceptually, the findings suggested that the intervention using area models and number lines, seemed to help these learners to read fractions using appropriate names; to identify the whole unit in the fraction models and to develop a sense of the size of fractions in relation to one whole unit. Procedurally, the learners compared and ordered fractions appropriately using either equal fraction bars, equal number lines, benchmarking or rules for comparing and ordering fractions with the same numerator or denominator; and learners used equal fraction bars to visually represent the lowest common denominator method and to recognise that only equally sized units can be counted together. This research identified four factors as possible influences of the teaching intervention. These factors are namely: identifying both fraction symbols and appropriate fraction names to see fractions as relational numbers; prompting to partition whole units of the fraction models and graphically illustrating fraction symbols to identify the whole unit in the fraction models and to develop a sense of the size of fractions in relation to one whole unit; graphically illustrating fraction symbols using the models to use equal fraction bars and number lines, benchmarking and rules for comparing; and graphically illustrating fraction denominations using equal fraction bars to recognise that only equally sized units can be counted together. This research strongly suggests that the effective use of models has the potential to develop learners’ conceptual understanding of and procedural fluency with fractions in a number of ways.

- Description: The coronal mass ejections (CMEs) and solar flares associated with extreme solar activity may strike the Earth's magnetosphere and give rise to geomagnetic storms. During geomagnetic storms, the polar plasma dynamics may influence the middle and low-latitude ionosphere via travelling ionospheric disturbances (TIDs). These are wave-like electron density disturbances caused by atmospheric gravity waves propagating in the ionosphere. TIDs focus and defocus SuperDARN signals producing a characteristic pattern of ground backscattered power (Samson et al., 1989). Geomagnetic storms may cause a decrease of total electron content (TEC), i.e. a negative storm effect, or/and an increase of TEC, i.e. a positive storm effect. The aim of this project was to investigate the ionospheric response to strong storms (Dst < -100 nT) between 2011 and 2015, using TEC and scintillation measurements derived from GPS receivers as well as SuperDARN power, Doppler velocity and convection maps. In this study the ionosphere's response to geomagnetic storms is determined by the magnitude and time of occurrence of the geomagnetic storm. The ionospheric TEC results of this study show that most of the storm effects observed were a combination of both negative and positive per storm per station (77.8%), and only 8.9% and 13.3% of effects on TEC were negative and positive respectively. The highest number of storm effects occurred in autumn (36.4%), while 31.6%, 28.4% and 3.6% occurred in winter, spring and summer respectively. During the storms studied, 71.4% had phase scintillation in the range of 0.7 - 1 radians, and only 14.3% of the storms had amplitude scintillations near 0.4. The storms studied at SANAE station generated TIDs with periods of less than an hour and amplitudes in the range 0.2 - 5 TECU. These TIDs were found to originate from the high-velocity plasma flows, some of which are visible in SuperDARN convection maps. Early studies concluded that likely sources of these disturbances correspond to ionospheric current surges (Bristow et al., 1994) in the dayside auroral zone (Huang et al., 1998).

- Description: The land issue has remained a contentious one more than two decades into a democratic South Africa. With the dispossession of the indigenous people from their land stretching back as far as 1913, eviction of farm workers and farm dwellers has increased tremendously even in the post-Apartheid era. Thus, the main goal of this study is to analyse the impact of the eviction on the Radway Green farm workers’ community and to examine the factors affecting the generation of livelihood activities in their new settlement. In doing so, I used the Sustainable Rural Livelihoods Approach (SRLA) as my theoretical framework as it conceptually grounds my area of study. It was employed to analyse data gathered from the field through in-depth interviews, focus groups, key informant interviews and descriptive observation of the case study. The centrality of the SRLA concept is on rural development, poverty eradication and the ability or sustainability of the vulnerable and poor to cope with stresses and shocks as they make a living (Scoones, 1998: 5). In that regard, the theoretical framework became an important cornerstone in analysing the impact of eviction of the Radway Green farm workers’ community and examining the factors affecting the generation of livelihoods activities in their new settlement. To analyse the research findings, various themes were utilised Forced Evictions and Resettlement; Eviction or Displacement; The Struggles of Recreating Livelihoods; The Need for Security of Land Tenure and Access to Infrastructure. Under these themes, the study revealed how the eviction was detrimental to the livelihoods of the farm workers and farm dwellers as they lost the land that was a primary source for the construction of their livelihoods. They lost employment, homes, agricultural land for food security and natural resources, social and family structures and most importantly cultural disruption. It is well documented that the rural poor who constitute the farm workers and the farm dwellers are some of the vulnerable people who need constant governmental support through the promulgation of laws that protect them and assist in livelihood construction. Thus, this study also served to examine how the evicted workers and their families have settled into their new homes and how they, in conjunction with the Department of Rural Development and Land Reform and any other government agencies are faring in terms of the establishment of income generating projects for their livelihoods at the new settlement.

- Description: This thesis is a case study of how church, land and dispossession of land has influenced identity formation of a coloured community in the Eastern Province, namely the Klipfontein community. Coloured history in the Eastern Province has largely been neglected. This study attempts to rectify such a lack of in-depth enquiry as it may lead to misinterpretations that may influence contemporary politics and identity formation. Through research based on primary sources, it is evident that the social landscape of Klipfontein Farm and the relationships between that community and surrounding black African and white communities have largely been shaped by the stipulations contained in the joint will of the community’s ancestors: Dirk and Sarah Janse van Rensburg. The land devolved into a trust and has been administered by trustees since the death of the first spouse in 1877. By keeping the land in a trust, it enabled the descendants to continue to live on the farm in perpetuity, without the risk of being forced off the land via financial restraints or racially-based legislation. But the usufructuaries could also never fully utilise Klipfontein as an agricultural concern due to a combination of a lack of equipment and skill, and the provisions of the will. These complications inevitably led to inter-familial disputes and tension. Before 1939 there had already been three court cases dealing with the interpretations of the Will. In that same year the Supreme Court ordered that tracts of the land, including a part of Boesmansriviermond village, be sold in order to pay off arrear rates and taxes. Although the responsibility for these sales lay with the trustees, the community has been suspicious of the usufructuaries ever since. A key element of the Klipfontein identity is their religion. The church legitimises their right to the farm - against those who wish to take that right away. Their claim to occupation is couched in scriptural discourse, viewing Klipfontein as 'their Garden of Eden' that God gave to the stamvader, Dirk Janse van Rensburg. This seemed to have been partially successful for the Klipfontein community in staving off harassment by authorities. It also caused friction between the community and the black African residents. Some usufructuaries and family members felt that such right was exclusively given to the coloured community and so they became increasingly annoyed by the black Africans who settled there. Other usufructuaries did not share this feeling. They allowed evicted black African farm labourers to settle on certain portions of Klipfontein until the late 1970s. The black African population rapidly increased due to misinformation and evictions from neighbouring farms. This only further exacerbated the inter-familial conflict between usufructuaries, flaring tensions between the black Africans and their reluctant hosts as well as animosity from the white community towards Klipfontein. In 1979, after a series of court cases, a decision was made to remove all the African settlers by force and relocate most of them to the ‘homeland’ of Ciskei. The rest, who were of ‘working-age’ were left behind in a ‘temporary emergency camp’ on the outskirts of Kenton-on-Sea. The effects of these removals still impact the relationships between the different racial groups in the area to this day.

- Description: The right to language and the right to healthcare services are human rights which are enshrined in the Constitution of the Republic of South Africa. Section 6 (5) of the Constitution and Section 1.3 (b) and (e) of the Eastern Cape Provincial Language Policy provide protection against unfair discrimination on the grounds of language; while sections 30 and 31 (1) of the Constitution refer to people’s rights in terms of cultural, religious and linguistic participation. Section 27 (a) states that ‘everyone has the right to access to healthcare services’. In accordance with the Constitution, in 2011 the National Department of Health passed a Policy on Language Services. This policy aims to facilitate equitable access to government services and information, as well as respect for language rights as spelled out in the Constitution. The Policy on Language Services further aims to promote multilingualism in the National Department of Health and to allow people to access information in a language of their choice, understand important messages and the language necessary for informed and participatory decision making (Department of Health 2011:1). Given the above policy and Constitutional provisions as far as policy commitment is concerned, the crucial issue remains the implementation of such policy to ensure that the right to access to health and language are realised. The study provides an analysis of the Policy on Language Services 2011 as it relates to language rights and the delivery of health services, focusing on the roll out and implementation process and the public awareness of the policy. This study primarily focuses on the role language plays in accessing public healthcare in primary healthcare facilities in the Grahamstown and Cofimvaba. The study looked at communication between patient and healthcare providers and whether healthcare services were provided in the language of the patient or the language the patient knows best. This study further assessed indications of patients’ comprehension of information such as medical instructions on packaged medicine, comprehension of posters, pamphlets and health education sessions in order to fully participate in the process of their health status. The data of this research was collected from healthcare providers and patients in primary healthcare facilities in Grahamstown and Cofimvaba in the Eastern Cape. The research methods used was in-depth interviews, non-participant observations as well as content analysis such as sign/direction posts, medical labels and information boards. These methods were used to determine whether language plays a role in accessing quality healthcare services in these facilities. The research found that the lack of implementation of language and health policy resulted in the perpetuation of language barriers in the healthcare sector. The study therefore argues that adequate healthcare can only be provided if and when healthcare providers and patients are able to communicate with each other in the language they know best or feel most comfortable in. Thus meaning the implementation of the current Constitutional and policy provisions is crucial to language and access to healthcare services.

- Description: The problem of poor reading skills is a serious one in South Africa, with negative implications for learners’ educational achievement. The failure of learners to read at age- and grade-appropriate levels presents a major challenge to the teaching of reading in South African schools. It is against this background that this study aimed at ascertaining the positive impact of the Reading to Learn methodology in improving the literacy levels of learners in a Grade 10 English First Additional Language classroom in a township school. Reading ability levels were established via a passage extracted from a Grade Platinum English First Additional Learner’s book. Pronunciation and word recognition formed the basis of the reading assessment. Reading translates into writing, so the learners were also assessed in comprehension and creative writing. The results indicated that the learners’ reading abilities were weak, the methodology used to teach reading led to research findings that caused the study to yield findings that suggest that RtL may be the solution to reading problems in the classroom. In addition the study revealed that the ability to read corresponds with cognitive development. The study therefore calls for the adoption of RtL to assist in alleviating reading problems in the classroom.

- Description: The purpose of this study was to answer two main research questions: How is leadership promoted on a Representative Council of Learners (RCL) and What leadership roles do learners on the council play in schools? Recent research suggests that although the democratisation of school governance has given all stakeholders a voice in how schools are being governed, it seems that learner voice is still largely silenced. Literature on this issue paints an uninspiring picture of learner under-involvement and marginalisation. In seeking underlying causes for this, this study is informed by notions of leadership for social justice. The study investigated the RCL at a public, fee-paying school in the Makana district of the Eastern Cape. By observing the daily functioning of the council, engaging with the learner leaders as well as teachers, parents and other role players, I developed a better understanding of the challenges the RCL faced as well as factors which promoted their role as learner leaders. This aided in answering the first key research question of how the RCL promotes leadership development. To answer the second key question, I needed to consider the perceptions of stakeholders concerned and how they saw the operation of the RCL. This study is situated in the interpretive research tradition and uses critical realism as its under-labourer. To support this study and to answer some of the aims of this research, Leontiev’s second generation Cultural Historical Activity Theory was used. Data were collected through semi-structured interviews, questionnaires an observation and document analysis. Data analysis took the form of identifying themes which emerged from the data. These formed the basis of my discussion and I was thus able to address the main research questions. Data revealed that learner leaders in schools are mainly managers and not really leaders; that learners are still very much marginalised as leaders and that they subsequently do not have a lot of say when it comes to how their schools are governed. It further emerged that despite formal legislation and guidelines which are in place to allow for the democratic rights of learners’ opinions to be heard in schools, historical and cultural forces account for parents and other role players’reluctance to allow learners to have too much of a say. I trust that the findings from this research will strengthen learner leadership structures in schools and perhaps provide guidelines on how learner leadership could be developed and managed.

- Description: The ongoing and rapid change (from global to local level) in climate, populations, governments, cultures, environment, land use and economies are critical issues, especially for poor rural communities found in the dryland parts of southern Africa. The manifestations of change can combine to increase rural livelihood vulnerability, through the erosion of assets and insecurity, but can at the same time create new opportunities. Studies that consider the complex nature of change across scales and how it affects changes in livelihoods, ecosystems and responses at local level, are increasingly needed. This study, carried out in two purposefully selected study sites in the communal drylands of south-eastern Zimbabwe (Marwendo village) and Limpopo province in South Africa (Tshivhulani village), examined the complex nature of change across scales by assessing the way in which change at the global scale results in localised trends, shocks and stressors, and its impacts on livelihoods and ecosystems and responses over the past 30 years. The study applies social-ecological system thinking in understanding human-environment change. Particular emphasis was put on the role of social protection and natural resources in responding to change, shocks and stressors. The study employed a mixed method approach to gather data which included a household survey, life history interviews, transect walks, focus group discussions as well as secondary sources of information. The results of the study illustrate that shocks and stressors are common in both villages and are likely to increase in severity and frequency with ongoing and rapid human-environmental change, especially climate change. The local responses to change, shocks and stressors are primarily reactive and mainly intensify exploitation of existing natural resources and social protection as safety-nets. In Marwendo village, the villagers relied more on the use and sale of natural resource products readily available to them, whereas in Tshivhulani village they mainly tend to rely on social grants. Thus, in the future, households’ vulnerability might increase, and may be worse in Marwendo village, since important components of current livelihoods remain natural resource-based and climate sensitive. In Tshivhulani village, livelihoods characterised by high dependence on social grants can have severe consequences for households as children get older or elderly members die and grants cease to be available. Social grants therefore only really offer a temporary relief. This coupled with environmentally destructive practices such as brick-moulding in Marwendo village and uncontrolled settlements in Tshivhulani village may reinforce the negative impacts of change and thus undermine sustainable adaptation. The study concludes that multiple lenses for understanding the links between livelihood and ecosystem vulnerability in the context of the ongoing and rapid change are essential, and these provide insights into how different policy options for livelihood improvement and social protection might be appropriate for reducing household and ecosystem vulnerabilities in the future.

- Description: Taking insights from the domestic work literature both locally and internationally, this study explores the lived experiences of room attendants who work as cleaners in the students’ residences at Rhodes University. The study focuses on the housekeeping division of Rhodes University. Data was generated from in-depth individual interviews and focus groups with 26 women and 3 men participants (aged between 28 and 60) who work as room attendants, and who were recruited from the residences across the university. The phenomenological approach allowed the participants to articulate in-depth, their experiences of working as room attendants in intimate spaces. This study used a triangulated conceptual framework, which amalgamated the concepts of pain, social space and intersectionality, and exploitation under the umbrella concept of positional suffering. Within a higher education transformation agenda which has marginalised the experiences of unskilled workers at the university, the study seeks to bring insights to the understanding of transformation at Rhodes University through the experiences of the being-in-the-world of room attendants.

Lizalise Idinga Lakho [Honour Thy Promise]: The Methodist Church Women’s Manyano, the Bifurcated Public Sphere, Divine Strength, Ubufazi and Motherhood in Post-Apartheid South Africa

- Description: This study examines the socio-political role of the Christian church based women’s Manyano organisations in post-apartheid South Africa. Specifically, the study examines the ways in which the women’s Manyano organisations offer black women a site for the performance of citizenship. The study is based on life history interviews conducted with seventeen members of the Methodist Church Women’s Manyano of the Lamontville Circuit in Kwa-Zulu Natal. The study shows that dominant literature on Manyano women is primarily located in the historiography of the formation of Manyano groups within the historical development of the black church from the moment of missionary contact in South Africa. This literature shows that the missionaries used the coming together of black women in the church to promote ideas of devout domesticity that are based on Anglophone Victorian womanhood. This literature also shows that the structural constraints of colonisation and apartheid transformed the black church into a counterpublic space which focused largely on the liberation of the black majority from political, economic, and social exclusion from the colonial and apartheid public sphere. These constraints also transformed the role of women’s Manyano organisations to become an important space from which black women came to resist and defeat apartheid. This study shows that this historical framing of women’s Manyano groups has shaped their role in post-apartheid South Africa. Located in the African feminist theory, the study argues that Manyano women’s publicness is not limited to gendered expressions of the public and private sphere. Instead, Manyano women demonstrate that their publicness in post-apartheid South Africa ought to be understood through a combination of the varied identities that they straddle, such as those of a politically and culturally defined womanhood and communally based motherhood, which express their understanding and performance of citizenship. The thesis, therefore, argues that the contemporary role and functioning of Manyanos is located within both the hegemonic public sphere that is granted by the civil liberties of the new South Africa, and the historical black bifurcated counterpublic -which combined offer black women the ability to devise strategies to confront present-day socioeconomic challenges such as structural poverty that shapes the lives of the majority of black women in post-apartheid South Africa. The study contributes, therefore, to the reconstruction of the concept of the public sphere through the use of Manyano women’s dynamic position in post-apartheid South Africa. It shows that the dualist nature of Manyano women’s position and identity allows for a multifaceted approach in the understanding of citizenship for Manyano women today. Furthermore, and importantly, the study shows that the complex roles that Manyano women navigate within the different spheres complicate the interpretations of womanhood and motherhood as understood in dominant (white western) feminist theory in ways that often lead to the delegitimisation and erasure of Manyano women’s contributions to ideas about post-apartheid feminisms.

- Description: The way media is created and consumed plays an important role in political participation as it provides information, guides thinking and allows citizens to make informed political choices. It can also interrogate the status quo and challenge existing systems or power relations. This thesis discusses the use of social media by Rhodes University students in the context of the 2015 #RhodesMustFall and #FeesMustFall protests in South Africa. This thesis interrogates the concept of slacktivism, a term used to describe online or digital activism which is considered to be less active and not as effective as physical activism. Furthermore, the thesis acknowledges that even when digital political participation is recognised, the emphasis and value is placed on those who speak and create content. The thesis examines the notion of participation and what counts as active citizenship. In particular, the majority of social media users who merely lurk and never contribute to content creation or online discussions are further investigated. The qualitative methodological approach used for this thesis involved three parts which looked at student activity on Facebook, student engagement offline, and how students made sense of their online and offline involvement. Firstly, a cyberethnographic investigation was done in order to understand the cyber world in which students are present. Thereafter, a participant observation was carried out to immerse myself in the offline spaces that students engaged in politically, to get a better sense of how their online presence influenced or supplemented their offline activity. Finally, individual interviews were carried out with lurkers to determine why they did not participate in traditional ways, both online and offline. The findings suggest that lurkers are in fact doing more than just being passively present. The high levels of attention paid to content posted by others on social media, as well as the way that the content influences their offline lives suggest that the choice to lurk is far more active than assumed. Students are consciously deciding to lurk for a multitude of reasons, one of which is for the opportunity to learn. Social media is a fast developing; increasingly used form of communication and how political communication across social media platforms is framed affects what we consider to be active engagement. By using theories of listening and emotion talk, the thesis provides new ways of understanding lurking by Rhodes University students on social media, which in turn can lead to better listening, better understanding and greater political participation.

L’etude comparative des elements merveilleux dans trois epopees africaines: Soundjata ou I’epopee mandingue, Emperor Shaka The Great: a Zulu Epic et Nsongo’a Lianja: I’epopee nationale des Nkundo

- Description: This thesis is a comparative study in Francophone literature which analyses the supernatural factors in three African epics, namely the Sundiata or Mandingo Epic from West Africa by Djibril Tasmir Niane (1960), Emperor Shaka The Great : A Zulu Epic from Southern Africa by Mazisi Kunene (1979), and Nsongo’a Lianja : the National Epic of Nkundo People from Central Africa by Edmond Boelaert (1949). The study analyses similarities and differences between the supernatural figures in these epics and their respective societies using contextual and socio-critical theories. In this thesis it is demonstrated that the presence of supernatural forces is a sine qua non condition for the existence of the epic in the sense that : “the essential mark of the heroic personality in many African folk epics is its reliance on supernatural resources” (Okpewho 1979 : 119). This study shows that in Africa, supernatural forces play vital roles in the society and therefore dominate the African oral epic traditions. Furthermore, the study is significant in the sense that it tries to describe the worldview, especially the religious and cultural beliefs of the particular society or group that produces the epic. The thesis is made up of six chapters. In the first chapter, I outline the study’s subject matter, its aims and objectives, its significance, its assumptions and methodology. In the second chapter, I examine the impact of supernatural devices on the lives of the epic heroes Sundiata, Shaka, and Lianja, the predictions and divinations about their births, childhoods, exiles or epic journeys, their ascension to the throne as well as their genealogies and deaths. Such analysis allows one to identify the supernatural factors surrounding each stage of the life of the heroes, and to understand further the importance of supernatural forces in the communities and institutions where the heroes exercise their powers. In the third chapter, I discuss the typology of the supernatural forces in the heroic epics Sundiata, Shaka and Lianja, using Greimas’s theory of actants. I divide the characters into protagonists, accessories and opponents. In the fourth chapter, I examine the sources of the supernatural forces prevailing on Sundiata, Shaka, and Lianja. The chapter shows how supernatural agents act on the epic heroes and how these supernatural beings make or mar them in the course of the narratives. In the fifth chapter, I investigate the supernatural factors acting on the heroes’ opponents, and in chapter six, I examine the supernatural forces and heroism of the women in the three epics. In the conclusion, I demonstrate that this analysis of supernatural factors enables us not only to appreciate their place and function in the three African epics under study, but also opens a window onto the culture of the Mandingo, Zulu, and Mongo People’s : their activities, beliefs, taboos and the rules which organise their respective societies. , This thesis is presented in two parts: French and English.

- Description: George R.R. Martin’s fantasy series, A Song of Ice and Fire, has joined franchises like Harry Potter and The Lord of the Rings at the forefront of popular culture. Unlike other popular fantasy franchises, however, Song is notably ‘gritty’ - inspired as much by the realism of historical fiction as it is by its fantastical predecessors. The novels focus on a massive struggle for power, and that struggle is a famously bloody one: the violence of the novel’s medieval-inspired world and of medieval warfare, is placed front and center. This thesis argues that Song portrays this excessive violence with a view to more than mere sensation. The body is central to Martin’s text, and since power is the object of Martin’s characters, he depicts the way in which power interacts with the body with sophistication. The use of capital and corporal punishment is foregrounded frequently in the text, and presented as central to the process of ruling, but horrifying in its potential for injustice. For all that these acts of maiming - public execution, public torture - may be presented as ceremonies of justice, Martin makes it evident that they are in fact rituals of power. The spectacular display of maimed bodies occurs frequently - so frequently that it is clearly ordinary to Martin’s characters - and nearly always with a view to creating a perception of power. Heads are spiked on castle walls, gibbets hung in town squares, and slaves crucified on road-signs, and these all speak not of the criminality of the victims, but of the power of those doing the punishing. While such displays may be successful, they usually signal weakness to the reader: Martin writes numerous characters whose acts of violence come as misplaced reactions to their own vulnerability. This dynamic comes to the fore most powerfully in the absurd performances of violence by Theon Greyjoy, and, later, in his torture by Ramsay Bolton.
