- Description: This study investigates the Daily Nation and Standard’s news coverage of Kenya’s 2007/2008 general election and the unprecedented eruptions of violence which followed. This research responds to the question which came about as Kenyan print journalists and editors considered their role in possibly contributing to the violence, which took on an ethnic dimension. Vernacular radio has been fingered for having escalated longstanding ethnic tensions, but the role of the press has not been fully understood. In the aftermath of the violence, print journalists and editors met over a series of Round Table events in Nairobi to consider whether their conduct during the election could have encouraged violence. Although ten years have passed since this incidence, much of what happened within the Kenyan print media during and after the 2007/2008 general election remains unexplored and, largely, unexplained today. Although the pre- and post-election phases spanned months, my research is confined to purposive samples from a four-week period from 3 December 2007 to 4 January 2008. These four weeks were selected as they are roughly representative of the three phases of the national election which are considered significant to this study, namely the pre-election phase, the election, and the post-election violence. The research is concerned with analysing and understanding the coverage in the two dailies, the Daily Nation and Standard, and comparing the discursive work of the two, particularly in relation to identity and ethnicity. This study draws on cultural studies, critical discourse analysis and normative theories of the media to inform the research project. The critical discourse analysis explores the discourses articulated during and after the election, with a particular focus on issues of identity, ethnicity and incitement. Through this process the study found that both publications avoided references to ethnicity, despite this being an important factor in Kenyan politics and voter behaviour. In analysing these issues the study found that while the publications might claim to attempt to avoid fuelling tensions by not reporting on ethnicity, the disavowal comprised a silence which positioned the press in a collaborative role, in which it colluded with a powerful Kenyan state. Although a significant amount of time has gone by since the 2007/2008 elections, this study still considers the event significant in understanding the conduct of journalists during times of violence, and specifically for the future of journalism in Kenya.

- Description: People who have been diagnosed HIV positive often experience distress and anxiety due to uncertainties pertaining to the implications of an HIV positive status. Research has shown that support groups have always been a way for people to cope with the distress and stressful circumstances associated with health conditions such as HIV. This research investigated the role of face to face support groups in the lives of those living with HIV. The primary focus of this research project is to provide an in-depth exploration of HIV positive individuals‟ experiences of being in a support group. The study aims to explore the positive and negative experiences of being in an HIV support group and aims to gain an understanding of the role support plays in the lives of those living with HIV. A qualitative research design was used to explore the above mentioned aim. Semi-structured interviews were conducted with five individuals, (three women and two men) who had experienced HIV support groups. The interviews were transcribed and then analysed according to the principles of interpretative phenomenological analysis (IPA). The findings of this study revealed five super-ordinate themes, which revealed not only the positive and negative experiences of being in a support group, but also the challenges that the participants‟ experienced before joining the group. Getting a sense of the participants‟ experience before joining the group allowed the researcher to get a better understanding of how useful or not the support group has been in helping them deal with the challenges of living with HIV. The themes included: „struggling to survive after diagnosis‟, „struggling to cope: adopting negative coping skills‟, „experiencing a turning-point: a will to survive‟, „attending support group: a sweet experience‟ and lastly, „attending support groups: a bitter experience‟. Findings suggest that for these participants, the advantages outweighed the disadvantages of being in a support group. Therefore this study suggests that face to face support groups are a viable and even necessary option for support. These findings support previous research and literature in regards to the importance of social support in the form of support groups in effectively assisting HIV positive people in their journey to adjust to the consequence of living with HIV.

- Description: The world is becoming more complex due to the increasing occurrence of social-ecological change. This is particularly evident in the developing world, especially on the African continent, where existing vulnerabilities (i.e. endemic poverty, weak governance, overpopulation and HIV/AIDS) are being exacerbated by the impact of climate change. Climate change poses a very real threat to millions of Africans, especially those who rely on the natural world for their livelihoods. The increasing variability of climate and rainfall patterns are said to have dire consequences on agricultural production which is the main livelihood activity of rural dwellers across the continent. The impacts of such change and variability include, changes in the frequency and intensity of droughts, flooding and heavy storms, leading to worsening soil conditions, desertification as well as disease and pest out-breaks which will likely result in reduced crop and livestock yields. A reduction in agricultural production will likely have a negative effect on the food security of millions of people. This study was conducted in the Eastern Cape of South Africa, in two rural villages, Fairbairn and Ntloko located in the former Ciskei homeland, with the purpose of exploring the nexus between climate change, cultivation and food security. This study combined social-ecological thinking with that of political ecology to create a robust lens, in which to analyse the complex interactions between humans and the environment. A mixed methods approach was used to gather the data which consisted of a household survey, using a structured questionnaire as well as semi-structured interviews with various respondents. Quantitative data were analysed using Excel and Statistica 13, whilst coding was used for qualitative data. The main aim of the study was to explore the extent and characteristics of cultivation in the two study sites, the role of household food production in food security as well as the challenges that local cultivator’s face with regards to climate change. In recent decades, there has been a decline in rural agricultural production with many fields that were previously cultivated, lying vacant and unused. However, as this study found, cultivation is still important as over 50% of sampled households cultivated a small area within the homestead. This was mainly done to supplement household food expenditure in order to save cash incomes. The results also found that although participants had perceived negative changes in climate and rainfall (amount, onset, duration), it was not considered the most important challenge for own production. Rather, lack of fencing and capital were seen as major hindrances to efficient own production. Understanding the complexity of own production and food security under a changing climate can help form better and more resilient policies and strategies for rural development, in addition to strengthening future livelihoods of rural people in an ever changing world.

- Description: Multimodal biometrics has become a popular means of overcoming the limitations of unimodal biometric systems. However, the rich information particular to the feature level is of a complex nature and leveraging its potential without overfitting a classifier is not well studied. This research investigates feature-classifier combinations on the fingerprint, face, palmprint, and iris modalities to effectively fuse their feature vectors for a complementary result. The effects of different feature-classifier combinations are thus isolated to identify novel or improved algorithms. A new face segmentation algorithm is shown to increase consistency in nominal and extreme scenarios. Moreover, two novel feature extraction techniques demonstrate better adaptation to dynamic lighting conditions, while reducing feature dimensionality to the benefit of classifiers. A comprehensive set of unimodal experiments are carried out to evaluate both verification and identification performance on a variety of datasets using four classifiers, namely Eigen, Fisher, Local Binary Pattern Histogram and linear Support Vector Machine on various feature extraction methods. The recognition performance of the proposed algorithms are shown to outperform the vast majority of related studies, when using the same dataset under the same test conditions. In the unimodal comparisons presented, the proposed approaches outperform existing systems even when given a handicap such as fewer training samples or data with a greater number of classes. A separate comprehensive set of experiments on feature fusion show that combining modality data provides a substantial increase in accuracy, with only a few exceptions that occur when differences in the image data quality of two modalities are substantial. However, when two poor quality datasets are fused, noticeable gains in recognition performance are realized when using the novel feature extraction approach. Finally, feature-fusion guidelines are proposed to provide the necessary insight to leverage the rich information effectively when fusing multiple biometric modalities at the feature level. These guidelines serve as the foundation to better understand and construct biometric systems that are effective in a variety of applications.

- Description: This thesis is divided into three parts, united under the general theme of bioinformatics tool development and variation analysis. Part 1 describes the design and development of the Job Management System (JMS), a workflow management system for high performance computing (HPC). HPC has become an integral part of bioinformatics. Computational methods for molecular dynamics and next generation sequencing (NGS) analysis, which require complex calculations on large datasets, are not yet feasible on desktop computers. As such, powerful computer clusters have been employed to perform these calculations. However, making use of these HPC clusters requires familiarity with command line interfaces. This excludes a large number of researchers from taking advantage of these resources. JMS was developed as a tool to make it easier for researchers without a computer science background to make use of HPC. Additionally, JMS can be used to host computational tools and pipelines and generates both web-based interfaces and RESTful APIs for those tools. The web-based interfaces can be used to quickly and easily submit jobs to the underlying cluster. The RESTful web API, on the other hand, allows JMS to provided backend functionality for external tools and web servers that want to run jobs on the cluster. Numerous tools and workflows have already been added to JMS, several of which have been incorporated into external web servers. One such web server is the Human Mutation Analysis (HUMA) web server and database. HUMA, the topic of part 2 of this thesis, is a platform for the analysis of genetic variation in humans. HUMA aggregates data from various existing databases into a single, connected and related database. The advantages of this are realized in the powerful querying abilities that it provides. HUMA includes protein, gene, disease, and variation data and can be searched from the angle of any one of these categories. For example, searching for a protein will return the protein data (e.g. protein sequences, structures, domains and families, and other meta-data). However, the related nature of the database means that genes, diseases, variation, and literature related to the protein will also be returned, giving users a powerful and holistic view of all data associated with the protein. HUMA also provides links to the original sources of the data, allowing users to follow the links to find additional details. HUMA aims to be a platform for the analysis of genetic variation. As such, it also provides tools to visualize and analyse the data (several of which run on the underlying cluster, via JMS). These tools include alignment and 3D structure visualization, homology modeling, variant analysis, and the ability to upload custom variation datasets and map them to proteins, genes and diseases. HUMA also provides collaboration features, allowing users to share and discuss datasets and job results. Finally, part 3 of this thesis focused on the development of a suite of tools, MD-TASK, to analyse genetic variation at the protein structure level via network analysis of molecular dynamics simulations. The use of MD-TASK in combination with the tools developed in the previous parts of this thesis is showcased via the analysis of variation in the renin-angiotensinogen complex, a vital part of the renin-angiotensin system.

- Description: This study set out to explore and describe in the form of a qualitative case study, an iteration of a Fundisa for Change teacher professional development programme, in this case the Teaching Life & Living short course presented to seventeen teachers as part of their Advanced Certificate in Teaching (ACT) Senior Phase Natural Sciences, at the University of Cape Town. The focus of the research was on describing how the development of teacher environmental pedagogical content knowledge (PCK) was supported and constructed in the course. The Consensus Model of Teacher Professional Knowledge and Skill, an outcome of the 2012 PCK Summit, was used to define the concept of PCK and also contributed the concept of amplifiers and filters as processes that mediate the development of teacher PCK. The study drew on Borko’s (2004) model of a professional development system, using the elements of course, teachers, facilitators and context as an analytical framework. Data generated included a teacher contextual profile questionnaire, audio-recordings of group work, course outputs and reflection and evaluation forms. Data analysis had two phases: the first phase concentrated on the development of analytic memos based on particular data sources whereas the second phase worked across data sources to present the evidence relating to each of the professional development system elements. The study found that teachers were supported in the development of their environmental PCK by the collaborative learning opportunities afforded by the course. Emergent PCK was organised according to five components: assessment knowledge; pedagogical knowledge; content knowledge; knowledge of learners; and, curricular knowledge. Emergent teacher learning ranged in specificity from general, to subject-specific, to domain-specific, and lastly to topic-specific knowledge. Teacher beliefs and orientations, prior knowledge and contexts brought into the professional development system were described as amplifiers and filters to teacher learning of PCK. In particular there were several contextual factors that emerged as themes from the data that had potentially filtering effects. Recommendations included that facilitators create an atmosphere conducive to collaborative learning, that evidence of learner conceptual understanding be examined during the course, that teachers be exposed to in-depth examples of canonical PCK and that more modelling of formative assessment strategies are presented.

- Description: The Postmasburg Manganese Field (PMF), located in the Northern Cape province of South Africa, plays host to significant deposits of iron and manganese that have been utilized since their discovery in 1922 by Captain L.T. Shone. Further afield, lies the massive high-grade manganese deposit of the Kalahari Manganese Field (KMF), which drew attention away from the PMF after its discovery. These deposits are not limited to iron and manganese ore, but contain significant assemblages of alkali-rich rocks - which is the focus of this study. The existence of alkali-rich assemblages beneath conglomeratic iron-ore on farm Langwervacht, has come under investigation in this study, and in particular, the enrichment of these rocks in Ba, Na and Mn. Petrographic analysis of the clast-supported conglomerate unit (ore-zone), has uncovered the presence of vugs (up to 8mm across) which contain barite, K-feldspar and fluorapatite. In addition to this, the ore-zone of one of the three boreholes contains late carbonate veins (kutnohorite), which travel along Fe-clast boundaries, and exploit clast-fractures and areas of weakness. Further down, within the ‘enriched-zone’ of alkalis, the mineralogy is more diverse - containing elevated concentrations of Ba, Na and Mn. Seventeen distinct minerals containing these three key elements have been identified - along with one solid-solution series in the form of hollandite-coronadite. The existence of minerals such as natrolite, aegirine, albite, banalsite, barite, serandite, celsian and hollandite-coronadite are indicative of hydrothermal activity having influenced these rocks. Bulk-geochemistry was used to compare the major and trace elements of each borehole and the associated units. Both the trace elements and the REE’s from the ore-zone are enriched by an average of 5-10x relative to the BIF standard used - which immediately suggests an influx of elements. Compared to PAAS (Post Archaean Australian Shales), the ore-zone REE’s are slightly depleted, but more importantly the profiles are very similar to that of the Mapedi shales achieved in previous studies. This result points towards a strong shale influence in the ore-zone protolith. Expectedly, many of the enriched-zone trace elements and REE’s show far greater enrichment than what is observed in the ore-zone. Trace and Rare Earth Element profiles between the ore-zone and the enriched-zone are, however, generally correlative, with profiles reflecting similar enrichments and depletions for a given element - even within different rock units. This suggests that the hydrothermal fluid has moved in a general upward direction, reacting with host-rock units, and relinquishing elements carried in solution - wherever conditions have been favourable for the accommodation of these elements. This study has shed light on the relationship between the ore-zone and the enriched-zone, and results suggest that the process of alkali enrichment is not directly related to the process of upgrading of the iron ores. This is due to the extent of the alkali-enrichment below the ore-zone, as well as enrichment factors in some trace elements being superior to that of Fe2O3 in the ore- zone. Hence, both of these zones have both been affected by a later hydrothermal fluid. The source of the fluid is likely a mature basinal brine, of oxidized, alkaline nature - which leached elements (Ba, K, Na, Pb, Ca) from older rocks, and carried them in solution. On a local-scale, this fluid has exploited areas of weakness in the form of fractures, less consolidated conglomeratic material and crosscutting veins. Manganese and iron has been remobilized on a local scale - producing secondary textures and partitioning into phases such as Mn-rich calcite and serandite. Comparisons to other studies in the PMF and KMF have revealed very similar alkali-rich assemblages, bearing many of the same minerals observed in this study - even within more manganiferous deposits. These findings have led to suggestions of a possible regional-scale hydrothermal overprint, which may have imparted a similar geochemical signal over the entire region - with the assistance of faults and unconformities. Of course, proving this is no mean feat, but current work on the source of barium in barite, using Sr isotopes from samples across the region may shed light on the source of at least one key element of these deposits.

- Description: The Postmasburg Manganese Field (PMF), located in the Northern Cape province of South Africa, plays host to significant deposits of iron and manganese that have been utilized since their discovery in 1922 by Captain L.T. Shone. Further afield, lies the massive high-grade manganese deposit of the Kalahari Manganese Field (KMF), which drew attention away from the PMF after its discovery. These deposits are not limited to iron and manganese ore, but contain significant assemblages of alkali-rich rocks - which is the focus of this study. The existence of alkali-rich assemblages beneath conglomeratic iron-ore on farm Langwervacht, has come under investigation in this study, and in particular, the enrichment of these rocks in Ba, Na and Mn. Petrographic analysis of the clast-supported conglomerate unit (ore-zone), has uncovered the presence of vugs (up to 8mm across) which contain barite, K-feldspar and fluorapatite. In addition to this, the ore-zone of one of the three boreholes contains late carbonate veins (kutnohorite), which travel along Fe-clast boundaries, and exploit clast-fractures and areas of weakness. Further down, within the ‘enriched-zone’ of alkalis, the mineralogy is more diverse - containing elevated concentrations of Ba, Na and Mn. Seventeen distinct minerals containing these three key elements have been identified - along with one solid-solution series in the form of hollandite-coronadite. The existence of minerals such as natrolite, aegirine, albite, banalsite, barite, serandite, celsian and hollandite-coronadite are indicative of hydrothermal activity having influenced these rocks.

- Description: The main objective of this thesis is to understand and explain the ongoing construction of livelihood activities by urban households in the low-income high-density area of Budiriro, Harare, Zimbabwe in a context characterised by systemic crisis and a general decline of the national economy. The study utilised a mixed methods research approach, which combined both qualitative and quantitative research, including a survey, life histories and focus group discussions. The thesis discusses a diverse range of livelihood activities of Budiriro households, such as formal employment, informal trading and agricultural activities, and the ways in which households seeks to diversify their livelihood portfolio. It does this by way of also examining the contemporary and historical factors influencing the livelihood activities pursued by these households, along with the shocks and disturbances encountered and experienced by households in trying to construct viable livelihoods. The thesis makes useful contributions to the existing literature on livelihoods studies. Firstly, the thesis disaggregates the households by showing the existence of three wealth categories in Budiriro and the varying livelihood strategies of households in different wealth categories. Secondly, the study highlights the significance of intra-household dynamics in Budiriro for livelihoods as well as of inter-household kinship networks, which transcend the urban space and entail multi-spatial livelihoods. Thirdly, the thesis examines livelihoods over time, such that it goes beyond a strictly synchronic examination, therefore providing a diachronic analysis of diverse and complicated livelihood pathways. Finally, the Livelihoods Framework is located within broader macro-sociological theorising including the work of Pierre Bourdieu. In this respect, important insights arise about livelihood choices and practices in the light of ongoing debates within sociology about human agency.

- Description: Despite the prevalence of theories and research that could serve as guidelines for addressing intercultural communication challenges such as misunderstanding, ineffectiveness and inappropriateness in communication in Sino-African organisational contexts, the continued existence of these challenges suggests the inadequacy of such theories. Accordingly, in consideration of African and Chinese cultural perspectives, the aim of this study was to develop a hybrid intercultural communication congruence (HICC) framework in order to enhance intercultural communication and achieve intercultural communication congruence in Sino-African organisational contexts. In this study, intercultural communication congruence means effectiveness and appropriateness in intercultural communication. To achieve the study aim, an interpretive pragmatism paradigm was adopted, comprising a two-pronged approach of a synthesis of extant literature and theory as well as an empirical qualitative study, both underpinned by cross-cultural management theory. Based on the synthesis of literature and theory, a generic theoretical intercultural communication congruence framework underpinned by intercultural communication awareness - a state where communicants understand communication orientation and manner of communication in their own and their counterparts’ culture - was developed. A further contribution was a theoretical contextualisation of the generic theoretical intercultural communication congruence framework, resulting in a theoretical framework for intercultural communication awareness in Western, African and Chinese cultures and a theoretical intercultural communication congruence framework specific to Sino-African organisational contexts. Thereafter, with the aim of validating the intercultural communication awareness dimension of the theoretical intercultural communication congruence framework specific to Sino-African organisational contexts, an empirical study was conducted with a sample of seven African and eight Chinese experts using indepth interviews with open-ended and semi-structured questions. Based on qualitative content analysis, six intercultural communication awareness enablers or conditions that enable people to understand communication in different cultures and contexts for the purposes of attaining intercultural communication awareness emerged. These were cultural orientation, manner of communication, orientation to rules and protocol, individual dispositions, intercultural communication influences and intercultural communication variations. An integration of the intercultural communication awareness enablers into the generic theoretical intercultural communication congruence framework results in an updated generic theoretical intercultural communication congruence framework. Then, informed by the updated generic theoretical intercultural communication congruence framework, a further contribution of this study was an empirical verification of the intercultural communication awareness dimension of the theoretical intercultural communication congruence framework specific to Sino-African organisational contexts to result in a final hybrid intercultural communication congruence framework for Sino-African organisational contexts supported by the perspectives of those involved in interaction, rather than predetermined standards of other cultures. Empirical findings suggest that both African and Chinese colleagues maintain a sense of collectivism in the Sino- African organisational context, although this is demonstrated differently. In addition, African colleagues display a blended manner of communication characterised by a mix of Western and African ways while the Chinese manner is contextual and governed by roles and relationships. In African culture, rules and protocol are negotiated, aimed at social maintenance, while strong cultural patriotism ensures strict adherence in Chinese culture. In respect of individual dispositions, African people are seen as open and accommodating while the Chinese disposition could be described as closed and ambiguous. Also evident in the findings is the existence of within-culture differences and influence of noncultural factors on intercultural communication that should be addressed in order to achieve intercultural communication congruence. Finally, the frameworks developed and the methodological processes followed will stimulate academic debate and raise numerous questions for future research. Immediate future research could be geared towards refining the concepts of intercultural communication awareness, intercultural communication congruence and the hybrid intercultural communication congruence framework for Sino-African organisational contexts. At a management practice level, intercultural communication awareness insights provide a reference point for intercultural communication enhancement strategies and interventions in Sino-African organisational contexts.

- Description: With each passing year the number of Internet users and connected devices grows, and this is particularly so in Africa. This growth brings with it an increase in the prevalence cyber-attacks. Looking at the current state of affairs, cybersecurity incidents are more likely to increase in African countries mainly due to the increased prevalence and affordability of broadband connectivity which is coupled with lack of online security awareness. The adoption of mobile banking has aggravated the situation making the continent more attractive to hackers who bank on the malpractices of users. Using Open Source Intelligence (OSINT) data sources like Sentient Hvper-Optimised Data Access Network (SHODAN) and Internet Background Radiation (IBR), this research explores the prevalence of vulnerabilities and their accessibility to evber threat actors. The research focuses on the East African Community (EAC) comprising of Tanzania, Kenya, Malawi, and Uganda, An IBR data set collected by a Rhodes University network telescope spanning over 72 months was used in this research, along with two snapshot period of data from the SHODAN project. The findings shows that there is a significant risk to systems within the EAC, particularly using the SHODAN data. The MITRE CVSS threat scoring system was applied to this research using FREAK and Heartbleed as sample vulnerabilities identified in EAC, When looking at IBR, the research has shown that attackers can use either destination ports or IP source addresses to perform an attack which if not attended to may be reused yearly until later on move to the allocated IP address space once it starts making random probes. The moment it finds one vulnerable client on the network it spreads throughout like a worm, DDoS is one the attacks that can be generated from IBR, Since the SHODAN dataset had two collection points, the study has shown the changes that have occurred in Malawi and Tanzania for a period of 14 months by using three variables i.e, device type, operating systems, and ports. The research has also identified vulnerable devices in all the four countries. Apart from that, the study identified operating systems, products, OpenSSL, ports and ISPs as some of the variables that can be used to identify vulnerabilities in systems. In the ease of OpenSSL and products, this research went further by identifying the type of attack that can occur and its associated CVE-ID.

- Description: The paradigm shift engaged by countries in SADC and COMESA, such as Malawi, from the use of import substitution policies which were aimed at protecting their infant industries, to export led growth strategies, necessitated these developing countries to liberalise their economies. The liberalisation of these economies meant that, for them to attain development, they needed to trade more on the international market. However, with underdeveloped industries and a lack of local entrepreneurs who could provide export supplies to fill the void created by the liberalisation policies, developing countries had to look beyond their borders for investors. In pursuit of this objective, governments have been devising ways of attracting foreign direct investment which can stimulate export growth. One of the methods employed is the granting of investment incentives to would-be investors. Unlike developed countries who provide investment incentives in the form of financial incentives, developing countries grant fiscal incentives. These are incentives that reduce tax burdens of enterprises to induce them to invest in particular projects or sectors. One of the mediums of providing the incentives adopted by the developing countries is the use of EPZ schemes. EPZs provide incentives such as exemptions of direct and indirect taxes to companies that operate in the zones. However, being Members of the WTO and SADC and/or COMESA, these countries are bound by obligations regulating trade and investment as found in these Agreements. The expectation is that the fiscal incentives employed in the EPZs do not grant subsidies that are prohibited under the SCM Agreement and rules regulating subsidies in SADC and COMESA. In addition, even though the use of EPZs is not expressly proscribed under the SADC Protocol on Trade, it may be against the objectives of the Protocol - one of which is the pursuance of the inter-jurisdictional goal of cooperation in attainment of free trade among its members. Therefore, this study assesses whether the use of EPZs by some countries in the two RTAs (particularly Malawi) is in tandem with the subsidies regulation as found in the multilateral trading system and at regional level. It also assesses whether, if there is a breach of the same, it might be justified as part of the special and differential treatment accorded to developing countries by developed countries under the WTO. The study further assesses whether the use of EPZs might be against the spirit and objects of FTAs such as SADC.

- Description: According to the WHO, malaria is responsible for over half a million deaths annually especially in populations from disadvantaged settings. Although there has been a documented improvement in the mortality rates, malaria has proved to be a global emergency. Mostly affecting the poor population, this disease is perpetuating a vicious cycle of poverty in the developing world as current preventive measures are not adequate unless adopted in addition to effective treatment. However, there has been a worldwide increase in resistance to available treatment which presents a need for novel, affordable treatment. A study conducted in our laboratory identified two hit thiophenol containing compounds 2.24 and 2.25. These molecules provided initial insight into the SAR and potential pharmacophore of this class of compounds. We decided to further explore these compounds by making bioisosteric replacements to optimize the structure as we monitor the effect of these modifications on the anti-plasmodial activity. The synthetic pathway to form the target compounds of our study comprised of three steps which were initiated by the Friedel-Crafts acetylation of the indoles resulting in compounds 3.5 - 3.7. A bromination step followed which yielded the -bromo ketones (3.8 - 3.11). Some of the thiophenols (3.14 and 3.16) were not readily available in our laboratory and so were synthesized for the final synthetic step. This step involved the nucleophilic displacement of the -bromine to generate the -aryl substituted 3-indolylethanones (3.17 - 3.27). The thioethers displayed improved antimalarial activity from 2.24 and 2.25 against the chloroquine sensitive 3D7 Plasmodium falciparum strain. In addition, these compounds were non-toxic against HeLa cells which indicated this potential novel class of antimalarials is selective for the malaria parasite as hypothesized in the previous study conducted in our laboratory. In an attempt to predict the bioavailability of some of our compounds, in silico studies were conducted revealing that these compounds could be passively absorbed by the gastrointestinal tract, a positive result for bioavailability purposes. However, results from these studies indicate that modifications of these compounds would be necessary to allow for permeation through the blood brain barrier (BBB) for instances when the patient has cerebral malaria. , Thesis (MSc) -- Faculty of Pharmacy, Pharmacy, 2018

- Description: According to the WHO, malaria is responsible for over half a million deaths annually especially in populations from disadvantaged settings. Although there has been a documented improvement in the mortality rates, malaria has proved to be a global emergency. Mostly affecting the poor population, this disease is perpetuating a vicious cycle of poverty in the developing world as current preventive measures are not adequate unless adopted in addition to effective treatment. However, there has been a worldwide increase in resistance to available treatment which presents a need for novel, affordable treatment. A study conducted in our laboratory identified two hit thiophenol containing compounds 2.24 and 2.25. These molecules provided initial insight into the SAR and potential pharmacophore of this class of compounds. We decided to further explore these compounds by making bioisosteric replacements to optimize the structure as we monitor the effect of these modifications on the anti-plasmodial activity. The synthetic pathway to form the target compounds of our study comprised of three steps which were initiated by the Friedel-Crafts acetylation of the indoles resulting in compounds 3.5 - 3.7. A bromination step followed which yielded the -bromo ketones (3.8 - 3.11). Some of the thiophenols (3.14 and 3.16) were not readily available in our laboratory and so were synthesized for the final synthetic step. This step involved the nucleophilic displacement of the -bromine to generate the -aryl substituted 3-indolylethanones (3.17 - 3.27). The thioethers displayed improved antimalarial activity from 2.24 and 2.25 against the chloroquine sensitive 3D7 Plasmodium falciparum strain. In addition, these compounds were non-toxic against HeLa cells which indicated this potential novel class of antimalarials is selective for the malaria parasite as hypothesized in the previous study conducted in our laboratory.

- Description: Studies of ethnicity have shifted from primordialism to diverse variants of social constructivism, which include instrumentalism, invention of tribalism by the colonial elite and missionaries and demotic constructivism or creation of ethnicity from below. The studies have generally generated two broad schools of thought. One school avers that African ethnicity was invented by the colonial elite and missionaries in the colonial period whilst the other and more recent asserts that ethnicity had a precolonial currency and the generality of Africans also played a key role in identity formation. Also most notable is that most studies have tended to focus on larger and more visible ethnic groups, ignoring the stories of small communities mostly found in remote border areas of modern ‘nation’ states. Using archival material, colonial records, autobiographies, oral and secondary sources, this thesis, which is largely guided by the demotic constructivist theoretical perspective examines the evolution of the ethnic identity of an ‘obscure’ Hlengwe ethnic community of the south-east lowveld of Zimbabwe from the pre-colonial period to 2014. History of the Hlengwe history has been blurred by the use of the term “Shangaan” to denote the Hlengwe, yet they were not ethnically so. A chronological approach and demotic constuctivism have been used to enable a deeper analysis of the critical historical phases, key players and processes in Hlengwe identity formation as time wore on. While we acknowledge that identity formation involves diverse players, we also focus on the role of the generally neglected commoners in the making of African ethnicity. This study differs from other works on ethnicity which focus on events of short historical phases and the role of selected elitist agents in the making of African ethnicity, by analysing the making of Hlengwe ethnicity from the precolonial to the postcolonial period. We prove that Hlengwe ethnicity was created in the pre-colonial period but did not remain static as it was perpetually reshaped by unpredictable historical events right up to 2014. The Hlengwe community was subjected to processes of social transformation over a long period of time to an extent that the one time docile, ‘uncivilised”, inward looking community bearing an identity of shame had evolved by the close of the 20th century and early 21st century to an assertive community, proud of its identity and actively seeking political, economic and cultural recognition and rights for its ‘underdog’ Hlengwe constituency in a country where diverse Shona groups andNdebele form the dominant ethnic communities.

- Description: There is a growing body of research on sexual citizenship that focuses attention on gender and which bridges the gap between public and private life in order to rethink citizenship from a feminist perspective. This is in contrast to understandings of citizenship that promote policies of sexual regulation and a heteronormative ideal of citizenship. My research takes the form of a qualitative case study. Using data from two focus group discussions, fifteen personal diaries, as well as social media posts, I analyse participation in the Silent Protest, an annual anti-rape protest, through the lens of sexual citizenship. I look at how participation in the protest promotes or inhibits inclusive and process-based understandings of sexual violence and sexualities issues. Data were analysed using thematic analysis and the results of the analysis are presented into two parts. The first part of the analysis discusses the politics of affect and witnessing as two processes through which allies’ understandings of sexual violence are shaped. The second part of analysis shows that the Silent Protest contributes to people’s knowledge and understandings of sexual violence in relation to sexualities in a range of ways. Examples of inclusive understandings are: (1) insights about rape in relation to gender and heteronormative inequalities, culture and patriarchal dominance; (2) understanding of critical sexual citizenship in relation to sexual violence; and (3) understanding of politics of recognition (the need for recognition of the importance of safe spaces for formal and informal support for victim-survivors and recognition of victim-survivors’ identities). However, some of the understandings are limited to emotion and affect dynamics. In some ways, therefore, the Silent Protest fails to promote understandings significant to inclusive citizenship, including understandings of entitlements to non-discriminatory sexual health care services and legal services.

- Description: The Knysna seahorse Hippocampus capensis is South Africa’s only endemic seahorse species, and is found in only three adjacent estuaries along the southern coast. The conservation of this endangered species is important on a national and international level. This study presents the first research on this species within the Knysna estuary since 2001 and specifically focuses on aspects of its ecology within a residential marina estate (Thesen Islands Marina). The physico-chemical and habitat features of the marina were described and the population ecology, habitat use, and behaviour of the Knysna seahorse were investigated. Physico-chemical conditions within the western section of the marina, characterised by high water current velocities, were similar to that of the adjacent estuary. The eastern section of the marina was characterised by lower water current velocities and higher turbidity. Four major habitat types were identified within the marina canals: (I) artificial Reno mattress (wire baskets filled with rocks); (II) Codium tenue beds; (III) mixed vegetation on sediment; and (IV) barren canal floor. Seahorse densities within the marina were significantly higher compared to densities found historically within the estuary. Highest seahorse densities were specifically found within the artificial Reno mattress structures and within the western section of the marina. Seahorse density varied spatially and temporally and the type of habitat was an important predictor for seahorse occurrence. An experimental investigation found that H. capensis chooses artificial Reno mattress habitat over Zostera capensis when given a choice. GoPro cameras were used successfully to investigate daytime seahorse behaviour within the Reno mattress habitat. Seahorses were more active during the morning, spent most of their time (> 80 %) feeding, and morning courting behaviour for this species were confirmed. However, during the summer holiday period (mid-December to mid-January) few seahorses were observed on camera, which suggests that the increase in motor boat activity and the related increase in noise had a negative effect on H. capensis feeding and courting behaviour. The marina development, and in particular the Reno mattresses, created a new habitat for this endangered species within the Knysna estuary. In addition to the protection and restoration of natural habitats in which H. capensis is found, the conservation potential of artificial structures such as Reno mattresses should be realised.

- Description: Social-ecological sustainability challenges, from the local to the global level, are of increasing concern. Stewardship has been proposed as a means of dealing with these challenges, but how can it be achieved in practice? In South Africa, the concept is put into practice by practitioners working with local stewards to facilitate more sustainable and equitable management of ecosystem services across landscapes. This landscape approach requires collaboration between multiple stakeholders, as social-ecological processes function beyond the boundaries of individual farms or villages. The aim of this research was to investigate the practice of stewardship and collaboration in multifunctional landscapes in South Africa through a transdisciplinary enquiry. This was achieved using a methodological framework based on critical complexity, transdisciplinarity, and critical realism. This framework was applied through an inductive, mixed methods research design which involved stewardship practitioners, stewards, and other stakeholders in the research. Practitioners' understandings of the stewardship concept vary, yet they coalesce around the idea of responsible use and care of nature. Accordingly, the primary role of stewards is to interact with nature responsibly and carefully, balancing the use of ecosystem services for their own benefit with broader social- ecological interests and needs. Although the biodiversity stewardship tool dominates stewardship practice in South Africa, more integrated social-ecological initiatives are also emerging, often hand-in-hand with this approach. Practitioners working in these initiatives face multiple interacting and mutually reinforcing enablers and barriers that facilitate or hinder collaboration for stewardship. Individual and social-relational enablers are pivotal to long-term sustainability of initiatives, whilst deep-seated inequalities and mistrust are significant barriers to collaboration. Despite such challenges, practitioners are succeeding in fostering collaboration by operating as hubs in the landscape. They are actively building new relationships and networks among diverse stakeholders to address shared sustainability challenges. This results in a patchwork of collaborative stewardship activity across the landscape, suggesting that stewardship and collaboration are fundamentally relational processes and that pluralistic approaches to sustainability are needed in multifunctional landscapes. Moreover, by re-focusing stewardship on stewards, practitioners are finding innovative ways to enable farmers to appreciate and practice stewardship, addressing the conflict between agriculture and conservation. Drawing on these findings, a critical realist analysis revealed underlying generative mechanisms that help to explain the challenges encountered in collaborative efforts toward stewardship. These mechanisms included, amongst others: individual stewards' values, societal constraints on the ability of stewards to express care, conflict between agriculture and conservation due to dominant agricultural approaches and neoliberal economic policies, and the divided and unequal nature of South African society. Operationalising transdisciplinary research enabled meaningful engagement with practitioner partners, allowing for novel insights and unexpected findings to emerge from practice-based knowledge. Putting transdisciplinarity into practice revealed the dynamic and multi-faceted role that researchers can play in transdisciplinary research, highlighting the importance of relational knowledge and competencies. Existing support systems and incentives within universities need to be re-configured to enable postgraduate students to conduct engaged science in service of society. , Kuyanda ukuxhalatyiswa yimiceli mngeni yobudlewlane obuhlala buhleli bezentlalo nendalo, ekuhlaleni nakwihlabathi. Kuphakanyiswe umbono wobugosa-bumeli (ubuphathi bendalo, stewardship) ukuze kuhlangatyezwane nale miceli mngeni, kodwa iza kwenziwa njani le nto? EMzantsi Afrika le ngcamango iye yabekwa entsebenzweni ngabo banezakhono no bugcisa besebenza namagosa-bameli asekuhlaleni, benceda ekulawulweni ngendlela ehlala ihleli nelinganayo iinkonzo zobudlelwane nendalo kuyo yonke imihlaba. Le ndlela yokusebenzisa le mihlaba ifuna intsebenziswano phakathi kwabo bonke ababandakanyekayo, njengoko ubudlelwane bentlalo nendalo busebenza ngaphaya kwemida yomfama ngamnye okanye iilali. Injongo yoluhlolisiso ibikukuphanda ngoqheliselo lobugosa-bumeli nentsebenziswano yeemihlaba esebenza ngendlela ezininzi eMzantsi Afrika kubuzwa kumasebe olwazi ohlukeneyo olwazi(transdisciplinarity). Oku kwathi kwaphunyezwa ngenkqubo ehlola izinto ezahlukahlukeneyo kwimigangatho eyahlukeneyo, isekelwe kwingcamango enzulu kunoko kubonakala kuqondakalayo, kumasebe olwazi ohlukeneyo, nakulwazi lwesayensi nentlalo. Le nkqubo yenziwa kusetyenziswa inkqubo yokuqokelela ulwazi luze luhlalutywe, iintlobo ezahlukeneyo zokwenza uhlolisiso, ezazibandakandakanya abanezakhono zobugosa-bumeli, amagosa-bameli nabanye ababandakanyekileyo kolu hlolisiso. Ingcamango zabanezakhono zobubugosa-bumeli ziyohluka, kanti iingcamango zinye ngokuphathelele ukusetyenziswa nokukhathelela indalo yemvelo. Phofu ke, indima esisiseko yamagosa-bameli kukuphembelelana ngokufanelekileyo nangenkathalo nendalo, bethelekisa ukusebenzisa iinkonzo zobudlelwane nendalo ukuze zincede bona, kunye nomdla neemfuno eziphangaleleyo zobudlelwane bendalo nentlalo. Nakubeni isixhobo Sobugosa-Bumeli Bendalo Eyahlukeneyo Yezityalo Nezilwanyana (Biodiversity Stewardship) isesona sitshotsha phambili kuqheliselo lobugosa-bumeli eMzantsi Afrika, zikhona nezinye izixhobo ezivelayo eziqukwayo kwiphulo lobudlelwane bendalo nentlalo, ezisoloko zisebenza kakuhle neli lokuqala. Abanezakhono nabasebenza kula maphulo bajamelene neendidi zokuphembelelana, iingxaki ezahlukeneyo, izisombululo nezithinteli ezinceda okanye zonakalise intebenziswano yobugosa-bumeli. Isisombululo ngasinye nezo zayanyaniswa nentlalo zibaluleke gqitha kumaphulo azakuhlala ehleli, nakubeni ukungalingani okuzinze nzulu nokungathembani iyimiqobo ebelulekileyo kwintsebenziswano. Nangona ikhona le micelimngeni, abanezakhono bayaphumelela ekukhuliseni intsebenziswano ngokuthi basebenze kwiindawo ezithile kwimihlaba. Bakha unxulumano olutsha noqhagamishelwano nababandakanyekileyo ngokwahluka kwabo ukuze kusingathwe nemiceli mngeni yokugcina ubudlelwane bendalo nentlalo buhlale buhleli. Oku kuye kwaphumela kwintsebenziswano yobugosa-bumeli ethe yakho pha na pha kule mihlaba, nto leyo ebonisa ukuba ubugosa- bumeli nentsebenziswano ngokusisiseko yinkqubo enxulumeneyo, kwaye iindlela ezininzi zokwenza ubudlelwane bendalo nentlalo buhlale buhleli ziyimfuneko kwimihlaba ekwenziwa izinto ezininzi kuyo. Ngapha koko, ngokuthi kuphindwe kunikelwe ingqalelo kubugosa-bumeli isiya kumagosa bameli, abanezakhono bafumana iindlela ezintsha zokunceda amafama axabise aze aqhelisele ubugosa-bumeli, ngolu hlobo kusingathwa ingxabano phakathi kwezolimo nolondolozo lwendalo. Xa sifunda koku, ukucamngca nzulu ngako kutyhile enye indlela eye yanceda ekucaciseni imiceli mngeni ekuhlangatyezwane nayo kwimigudu yentsebenziswano yobugosa-bumeli. Ezi ndlela zibandakanya, phakathi kwezinye: indlela aziphatha ngayo amagosa-bameli, iingcinezelo yabahlali ekubeni amagosa-bameli abonakalise inkathalo, ukungavisisani phakathi kwezolimo nolondolozo lwendalo ngenxa yendlela ezongamelayo nezisetyenziswayo zolimo, nemigaqo-nkqubo yezoqoqosho elawulwa bucala, nokwahlukana, ukungalingani kwabantu baseMzantsi Afrika. Ukusebenzisa uhlolisiso lwamasebe olwazi ohlukeneyo kubangele ukufuthelana okunentsingiselo namaqabane abo banezakhono, oku kuvulele iingcamango ezinzulu nokufumana izinto ebezingalindelekanga kulwazi olusekelwe kuqheliselo. Ukubeka ulwazi lwamasebe ahlukeneyo entsebenzweni kutyhile iindima ezahlukeneyo okanye ezininzi ezidlalwa ngabahlolisisi kuhlolisiso lolwazi lwamasebe ohlukeneyo, kubalaseliswa ukubaluleka kolwazi olunxulunyaniswayo nozimiselo. Iinkqubo zenkxaso nezinye izinto ezincedayo ezikhoyo kwiyunivesiti kufuneka ziphinde zakhiwe ukuze zincede abafundi abenza uhlolisiso balwenze benomfutho wesayensi enceda abahlali.

Le nkqubo yenziwa kusetyenziswa inkqubo yokuqokelela ulwazi luze luhlalutywe, iintlobo ezahlukeneyo zokwenza uhlolisiso, ezazibandakandakanya abanezakhono zobugosa-bumeli, amagosa-bameli nabanye ababandakanyekileyo kolu hlolisiso. Ingcamango zabanezakhono zobubugosa-bumeli ziyohluka, kanti iingcamango zinye ngokuphathelele ukusetyenziswa nokukhathelela indalo yemvelo. Phofu ke, indima esisiseko yamagosa-bameli kukuphembelelana ngokufanelekileyo nangenkathalo nendalo, bethelekisa ukusebenzisa iinkonzo zobudlelwane nendalo ukuze zincede bona, kunye nomdla neemfuno eziphangaleleyo zobudlelwane bendalo nentlalo. Nakubeni isixhobo Sobugosa-Bumeli Bendalo Eyahlukeneyo Yezityalo Nezilwanyana (Biodiversity Stewardship) isesona sitshotsha phambili kuqheliselo lobugosa-bumeli eMzantsi Afrika, zikhona nezinye izixhobo ezivelayo eziqukwayo kwiphulo lobudlelwane bendalo nentlalo, ezisoloko zisebenza kakuhle neli lokuqala. Abanezakhono nabasebenza kula maphulo bajamelene neendidi zokuphembelelana, iingxaki ezahlukeneyo, izisombululo nezithinteli ezinceda okanye zonakalise intebenziswano yobugosa-bumeli. Isisombululo ngasinye nezo zayanyaniswa nentlalo zibaluleke gqitha kumaphulo azakuhlala ehleli, nakubeni ukungalingani okuzinze nzulu nokungathembani iyimiqobo ebelulekileyo kwintsebenziswano. Nangona ikhona le micelimngeni, abanezakhono bayaphumelela ekukhuliseni intsebenziswano ngokuthi basebenze kwiindawo ezithile kwimihlaba. Bakha unxulumano olutsha noqhagamishelwano nababandakanyekileyo ngokwahluka kwabo ukuze kusingathwe nemiceli mngeni yokugcina ubudlelwane bendalo nentlalo buhlale buhleli. Oku kuye kwaphumela kwintsebenziswano yobugosa-bumeli ethe yakho pha na pha kule mihlaba, nto leyo ebonisa ukuba ubugosa- bumeli nentsebenziswano ngokusisiseko yinkqubo enxulumeneyo, kwaye iindlela ezininzi zokwenza ubudlelwane bendalo nentlalo buhlale buhleli ziyimfuneko kwimihlaba ekwenziwa izinto ezininzi kuyo. Ngapha koko, ngokuthi kuphindwe kunikelwe ingqalelo kubugosa-bumeli isiya kumagosa bameli, abanezakhono bafumana iindlela ezintsha zokunceda amafama axabise aze aqhelisele ubugosa-bumeli, ngolu hlobo kusingathwa ingxabano phakathi kwezolimo nolondolozo lwendalo. Xa sifunda koku, ukucamngca nzulu ngako kutyhile enye indlela eye yanceda ekucaciseni imiceli mngeni ekuhlangatyezwane nayo kwimigudu yentsebenziswano yobugosa-bumeli. Ezi ndlela zibandakanya, phakathi kwezinye: indlela aziphatha ngayo amagosa-bameli, iingcinezelo yabahlali ekubeni amagosa-bameli abonakalise inkathalo, ukungavisisani phakathi kwezolimo nolondolozo lwendalo ngenxa yendlela ezongamelayo nezisetyenziswayo zolimo, nemigaqo-nkqubo yezoqoqosho elawulwa bucala, nokwahlukana, ukungalingani kwabantu baseMzantsi Afrika. Ukusebenzisa uhlolisiso lwamasebe olwazi ohlukeneyo kubangele ukufuthelana okunentsingiselo namaqabane abo banezakhono, oku kuvulele iingcamango ezinzulu nokufumana izinto ebezingalindelekanga kulwazi olusekelwe kuqheliselo. Ukubeka ulwazi lwamasebe ahlukeneyo entsebenzweni kutyhile iindima ezahlukeneyo okanye ezininzi ezidlalwa ngabahlolisisi kuhlolisiso lolwazi lwamasebe ohlukeneyo, kubalaseliswa ukubaluleka kolwazi olunxulunyaniswayo nozimiselo. Iinkqubo zenkxaso nezinye izinto ezincedayo ezikhoyo kwiyunivesiti kufuneka ziphinde zakhiwe ukuze zincede abafundi abenza uhlolisiso balwenze benomfutho wesayensi enceda abahlali.

- Description: As an academic and applied discipline, sport psychology is interested in identifying, understanding, measuring and developing the various mental constructs that interact with physical factors, aiming to produce optimum performance and enhance athletes’ experience of sport participation. The programmes developed within sport psychology are not only applicable to sport, but have applicability within other areas, such as the performing arts, business and professions that are considered high risk, such as the military. Using a mixed methods approach and a triangulation of qualitative and quantitative data collection and analysis techniques, the goal of this research was to document the process of developing and implementing a psychoeducational mental toughness programme and to evaluate the programme through exploring the participant’s subjective experience of such a programme. The aim of the research was to contribute to the existing literature on mental toughness programmes. This was attained through administering the Sport Mental Toughness Questionnaire (SMTQ) and a semi-structured interview, which informed the development and implementation of a psychoeducational mental toughness programme relative to the idiosyncrasies of the participant and grounded in strengths-based approaches to mental toughness development. Results were obtained based on post-implementation data collected through a second administration of the SMTQ and a semi-structured interview. The participant experienced the programme as positive and results were indicative of changes in his experiences of self-confidence and control, related to the global themes of mindset, flexibility and mindfulness.

- Description: There is an increasing call for conservation programmes to provide sound evidence of effectiveness, and employing empirical evaluations can assist in the transition to evidence-based conservation practices. The objectives of this research were to develop a logic model for the CapeNature Stewardship Programme which would articulate the programme's theory of operation with respect to its Stewardship Programme landholders. The second major objective was to develop psychometric instruments for assessing the motivations and satisfactions of the programme's stewardship landholders. Both objectives included the aim to provide robust and repeatable instruments for exploring landholder's psychology, and developing a programme's theory of operation to understand the programme and improve with understanding the needs of the landowners. In this regard the processes and methodologies employed represent a major component of this research. A mixed methods approach was utilized, including stakeholder and volunteer surveys, conducted via mailing hardcopies and the internet, together with three focus groups held with the programme's management, extension staff and the stewardship landholders. Analysis of the data thus collected included both qualitative and quantitative approaches, specifically coding and content analysis, together with statistical tests of internal consistency, factor analysis and doubling correspondence analysis. Robust indices for example validity and internal consistency were developed for assessing landholder’s satisfaction with extension and level of satisfaction with the stewardship programme (Babbie 2007). These indices revealed that landholders in the Stewardship Programme are not satisfied with the programme, and exhibit behaviours suggesting they act as advocates for the programme. Demographic data and additional information provided further insights into the programme. The development of a method for articulating the programme's theory of operation is represented, together with four logic models which graphically illustrate this theory. This process and theory allowed for recommendations to be provided for the programme's improvement. A platform for adaptive management and further evaluations of this, and similar programmes, represents a major outcome of this research, understanding the extension capacity needs for the conservation of biodiversity in the CapeNature Stewardship Programme to function as a model for improving the implementation of the programme across the Western Cape, South Africa. This research feeds into an evaluation of CapeNature’s Biodiveristy Stewardship programme and demonstrates the importance of incorporating psychology into conservation interventions.

- Description: The need to develop interculturally competent graduates is a concern for universities across the world. In South African universities this need is linked to globalization and increased diversity in terms of student demographics since 1994. Considering the legacy of apartheid, South African universities especially, and pressingly, need to respond to both global and national diversity concerns. ICC can play a significant role in creating more culturally inclusive spaces as students are provided with opportunities to “relate to and with people from vastly different cultural and ethnic backgrounds” (Spitzberg & Changnon, 2009, p. 4). In a similar way, Germany has faced, and continues to face, challenges relating to diversity especially in relation to migrants and as such, interculturality is a topic of debate in society and scholarly discourse. Therefore, ICC is as relevant to German society as it is South African society. Courses that explicitly deal with ICC are however, not common in South African universities and discourse, and as a result universities are “missing out on developing students’ intercultural competence” (Deardorff & Quinlan, 2016). This thesis aimed to address this gap by investigating the viability and necessity of introducing a module that deals explicitly with ICC into the German Studies course at Rhodes University. In doing so it contributed to the creation of disciplinary knowledge as well as furthering the aim of aiding the creation of responsible global citizenship, alongside ‘academic citizenship’, and aiding the internationalisation at home concept by encouraging the students to understand their own lived reality in a diverse society. This research made use of an action research approach to implementing a module and tracing its development. Student responses, as well as reflection and observation, found that a module dealing explicitly with ICC was viable and able to contribute to developing students’ sense of cultural self-awareness and their awareness of ICC as a set of transferrable skills and knowledges. This module aimed to serve as an introduction to ICC for students in order to begin to develop their intercultural competence and increase their awareness and critical approach to culture and intercultural encounters.
