- Description: The purpose of this study was to identify and analyse in an historical context the major changes to the United States’ Internal Revenue Code during the period 1981-2001. This qualitative study relied on historical and legal interpretative approaches to better understand the political forces, personalities, and interactions that helped shape the legislative changes during this time period. The study focused on deep analysis of primary sources that best illuminated the latent narrative of four major tax actions: The Economic Recovery Tax Act of 1981, the Tax Reform Act of 1986, The Omnibus Budget Reconciliation Act of 1993, and The Economic Growth and Tax Relief Reconciliation Act of 2001. Archives, periodicals, and political rhetoric were examined in order to help shape the historical narrative. In addition, this study sought to identify major trends and paradigm shifts in the way United States tax policy was formed during the time period examined. The study identified several key trends that emerged in United States’ tax policy during this period: the use of budget deficits as political tools; factors associated with accomplishing tax reform; gaps between political rhetoric of individual politicians and their political action; and the virtual disappearance of a political middle ground in United States budget politics. The study concluded by noting the economic and political significance of budget deficits and stressing the need for fundamental changes in voter responsibility in helping achieve lasting, broad-based tax reform and budgetary responsibility in the United States.

- Description: This study set out to evaluate the development potential of extractive sector corporate social investments (CSI) in Cameroon. It does this by evaluating the extent to which extractive companies effectively integrate CSI in their business operations and how this can be improved upon for more effective development outcomes in the country. The study premises that CSI can contribute to development but its activities will not always amount to just, balanced and sustainable development outcomes. To understand the extent to which it does, this study develops and applies a framework for determining the applicability and effectiveness of extractive sector CSI practices. The research followed an interpretivist philosophical orientation. A case study research strategy with the elements of a survey research was used. It also implemented a mixed research methods approach and relied on both primary and secondary data sources. The CSI evaluation process used documentary survey techniques and content analysis of corporate social responsibility-related documentation provided by extractive companies and other sector stakeholders. This was triangulated with an expert survey as well as a survey of major development organisations to understand the opinion of the external environment that should shape CSI practices. Results were analysed, discussed and synthesised using the front-end, mid-phase and back-end criteria for evaluating CSI integration. Findings show significant level of adherence to the discretionary idea of CSI among extractive firms working in Cameroon. This is due partly to growing social responsibility awareness among extractive firms around the world and the consequence of inaction. The greater majority of companies however, do not show strong proof of well thought out CSI implementation strategies. The feeling among experts is that extractive sector CSI in Cameroon is failing. It is predominantly self-regulated by extractive companies which raise questions regarding objective and credible CSI practices. The study concludes that CSI has been implemented in ad-hoc, haphazard and un-systematic ways. It has a viable potential to contribute to development but still suffers from a very weak CSI enabling environment as well as the challenges of sustainable development. Extractive sector CSI therefore, still needs to be significantly reworked to enhance its potential in contributing to just, balanced and sustainable development in Cameroon. It is recommended that an enabling environment be put in place through CSI promotional activities in the country.

- Description: Introduction: Marine finfish including dusky kob (Agyrosomus japonicus), in addition to its high protein value, is bestowed with numerous health benefits including being heart friendly due to high proportion of omega 3 fatty acids. They are therefore used as powerful preventive measures against cardiovaslcular diseases. They are also important in neurological development during gestation and infancy, thus a regular recommendation by nutritionists. However, fish and its environment may be contaminated by bacteria pathogens. Human infections caused by members of the genus Vibrio, and Staphylococcus especially Methicillin-resistant S. aureus (MRSA) are of increased concern worldwide especially with increased Vibrio disease outbreaks and rapid spread of MRSA in the community. Methicillin-resistant Staphylococcus aureus is regarded as an emerging zoonotic agent, therefore marine fish may be considered as a reservoir for infection. The emergence of multi-drug resistant organisms in both farm animals and humans has also been a challenge that hurdles chemotherapy worldwide. Methods: We enumerated the bacteria flora of skin, gill and gut of marine dusky kob (Agyrosomus japonicus) raised in a recirculatory aquaculture system using metagenomic sequencing of the 16S rRNA. We further screened 120 dusky kob fishes (skin, gill and gut) and 80 water samples from two fish farms and Kariega estuary collected over a 10 month period for human pathogenic vibrios, and MRSA using standard procedures. Vibrio species were further subjected to species specific PCRs delineating them into V. cholerae, V. parahaemolyticus, V. vulnificus, and V. fluvialis. This was followed by elucidation of the genotypic virulence determinants. The Reverse Fragment Length Polymorphism (RFLP) of the cytotoxin hemolysin (vvhA) gene of V. vulnificus strains was carried out to determine the associated biotypes. A total of 277 Vibrio strains consisting of 126 V. fluvialis, 45 Vibrio vulnificus, 30 V. parahaemolyticus and 76 vibrios belonging to other species were subjected to susceptibility testing to 15 antibiotics by the disc diffusion method and resistant strains were further evaluated for their genotypic antimicrobial resistant determinants by polymerase chain reaction followed by plasmid profiling. For MRSA screening, we evaluated the reliability of cefoxitin disc diffusion, oxacillin screen agar and BrillianceTM MRSA 2 agar tests, in detecting methicillin resistance from fish (environmental) samples using PCR detection of the mecA as the gold standard. A total of 33 mecA positive S. aureus strains (MRSA) were subjected to PCR detection of enterotoxins (Staphylococcal enterotoxin A-E) and Panton Valentine Leucocidin (PVL) encoding genes. The SCCmec types were also investigated by multiplex PCR targeting genes encoding type I-V. The antibiogram profiles of MRSA strains to 12 antibiotics by the disc diffusion method and to vancomycin by broth micro dilution method were elucidated. Polymerase chain reaction was employed to evaluate the presence of antibiotic resistant genes. The nucleotide sequences of the rpoB gene were analysed to determine mutations that could lead to rifampicin resistance. Results: A broad diversity of pathogenic and non-pathogenic bacterial species of different taxonomic groups was observed with Proteobacteria revealed as the most common bacteria phyla. Fifty one families were identified with Enterobacteriaceae the most frequently detected in all the anatomical sites and the gut showing the highest species diversity. A total of 606 (60.23 percent ) presumptive Vibrio isolates were confirmed by PCR of which V. fluvialis was the most predominant, 193 (31.85 percent ). This was followed by Vibrio vulnificus 74 (12.21 percent ), and V. parahaemolyticus 33 (5.45 percent ). No V. cholerae strain was detected. Only one of the V. parahaemolyticus strains possessed the trh virulent gene with no tdh detected. Virulence factors of V. fluvialis detected were stn (13.5 percent ), hupO (10.4 percent ), and vfpA (1.0 percent ). V. vulnificus biotype 3, formerly restricted to Isreal was identified. Generally, resistance among Vibrio isolates varied considerably with highest resistances recorded to amoxicillin (76.2 percent ), ampicillin (67.5 percent ), erythromycin (38.3 percent ), and doxycycline (35.0 percent ) while higher susceptibilities were revealed by gentamicin (100 percent ), norfloxacin (97.8 percent ), florfenicol (90.3 percent ), tetracycline (87.7 percent ), and chloramphenicol (87.4 percent ). Multiple antibiotic resistance (MAR) (resistance to ≥ 2 classes of antibiotics) was 58.5 percent . The MAR index did not vary significantly between sites (P>0.05) and values of >0.20 were recorded in 40 percent (108/277) of all the isolates. The resistant genes ampC, blaOXA, tetA, tetM, dfr1, sul1, sul2, ermB, nptII and strA were detected in two or more Vibrio isolates while the SXT intergrase was detected only in one isolate. Seven of the 18 extreme drug resistant isolates possessed 1–3 plasmids of 1.5–10 kb range. A total of 321 presumptive Staphylococcus aureus isolates were recovered by culture out of which 202 (62.9 percent ) were identified as S. aureus by PCR. Of these, 33 (16.3 percent ) strains were mecA positive while the rest, 169 (83.7 percent ) were mecA negative. The sensitivity and specificity of MRSA detection by use of cefoxitin disc (30 μg) test was 93.9 percent and 91.7 percent , that for oxacillin screen agar test (6 μg/mL) was 81.8 percent and 92.3 percent while that of BrillianceTM MRSATM 2 agar was 87.9 percent and 94.1 percent respectively. Staphylococcal enterotoxin SEE was detected in 12.1 percent (4/33) of total strains followed by SEA 3.0 percent (1/33), and SEC 3.0 percent (1/33). SEB and SED were absent. Six of the isolates had the PVL gene, giving a prevalence of 18.2 percent . The most frequently detected SCCmec type was SCCmec type III (17/33; 51.5 percent ), closely followed by SCCmec subtype IVc (10/33; 30.3 percent ) and the least were SCCmec types I and II with only 3.0 percent (1/33) each. The rest four (4/33; 12.1 percent ) did not belong to any of the above types and were therefore considered to belong to other subtypes of SCCmec type IV not tested in the study. For antibiogram patterns, 12 (36.4 percent ) strains were resistant to doxycyline, 10 (30.3 percent ) to trimethroprim-sulfamethoxazole, 9 (27.3 percent ) to tetracycline and only 1 (3.0 percent ) strain was resistant to ciprofloxacin. Nineteen (57.6 percent ) of the MRSA strains had vancomycin MIC of ≤ 2 μg/mL, 4 (12.1 percent ) with MIC range of 4-8 μg/mL, and 10 (30.3 percent ) with values ≥ 16 μg/mL. Overall, 27 (91.percent) isolates showed simultaneous resistance to 3 or more antibiotics. The resistant genes tetM, tetA, ermB, BlaZ femA were detected in two or more strains resistant to various antimicrobials. Resistance to rifampicin was not caused by mutations in the rpoB gene. Conclusions: To the best of our knowledge, this study is the first study reporting a broad, and diverse bacteria flora of skin, gill, and gut of the South African dusky kob as well as the first study on human pathogenic vibrios, and MRSA from marine finfish especially those from recirculatory aquaculture systems. Also, our study revealed that Vibrio species with pathogenic potential are present in marine dusky kob and its environs. Dusky kob is contaminated with CA- MRSA and HA- MRSA that may cause difficult to treat infections with regular antibiotics. Some of the MRSA strains contained toxins that can cause food-borne gastroeneteritis. The present study revealed that MRSA and Vibrio species are potential reservoirs for antibiotic resistant genes, which could be disseminated to other bacterial species probably through plasmids, a public health risk.

- Description: There is an abundance of evidence suggesting that all is not well in mathematics education in South Africa. It is also common cause that the role of mathematics teachers is central to finding sustainable solutions to what is commonly referred to as a mathematics crisis. The purpose of this study is to explore the process of change in selected mathematics teachers’ identities as they participated in a mathematics teacher Professional Development Programme (PDP) at Rhodes University. The core of the PDP was a teacher enrichment programme called the Mathematics Teacher Enrichment Programme (MTEP), under the aegis of the First Rand Foundation (FRF) Mathematics Education Chair at Rhodes University. MTEP foregrounded and emphasized the teaching of mathematics for conceptual understanding. The research approach was qualitative, and it used elements of the methods associated with educational ethnography. The data was collected from five teachers from five different schools that participated in the FRF Maths Chair project. I used Wenger’s (1998) three modes of belonging to analyse the identities of the five participants. This was achieved through analysing the teachers’ practice with a particular focus on teaching for conceptual understanding. I used Sfard & Prusak’s (2005) framework to analyse the participants’ journey from an actual to a designated identity through their participation in MTEP. The participants’ changing sense of belonging to MTEP was a key element in transforming their practice to teaching for conceptual understanding. I assumed the role of a participant observer during MTEP sessions, and of an outside observer as a researcher.The study found that the selected teachers’ participation in the MTEP community of practice strongly encouraged them to accumulate shared histories of learning and teaching. The study found that as participating teachers adopted and grew into their designated identity they partially embraced and implemented a conceptual teaching approach. The gap between their actual and their designated identity was partly closed as they sought to align their teaching with MTEP’s goal of conceptual teaching.

- Description: There is consensus that Small to Medium Enterprises (SME) exports play a critical role in the development of economies. It has been widely acknowledged in empirical research done around the world that small businesses make a significant contribution to economic development, employment, competitiveness and the reduction of regional disparities. However, empirical literature gives conflicting evidence on the determinants of export performance among SMEs. The study contributes towards the debate on SME exports by: (i) investigating the variables that determine export performance among SMEs in Zimbabwe (ii) establishing the competi-tiveness of Zimbabwe’s exports and (iii) ascertaining the major constraints faced by SME ex-porters in Zimbabwe The researcher gathered data from 120 SMEs and 10 institutions in Zimbabwe for the period 2009 to 2015. SME samples were chosen from Harare, Mashonaland Central and Mashonaland East provinces while all 10 of the institutions were chosen from Harare province. Convenient non-probability sampling method was used to select SMEs while stratified sampling technique was applied in the selection of institutions. Both qualitative and quantitative research methods were employed. For the quantitative approach, panel data ordinary least squares method was used in the form of the gravity model of trade. Export intensity (used as a measure of exports) was regressed against support institutions, business ownership, research & development, educational years, use of export processing zones, product type, export years, firm size, firm age, gender, distance from trading partner, Gross Domestic Product (GDP) of trading partner, and GDP of Zimbabwe. The random effects estimation method was used, basing on results from the Durbin-Wu-Hausman test. The null hypothesis was based on the premise that the variables under study do not determine export intensity of SMEs in Zimbabwe. Other null hypothesis were that the major constraint faced by SME exporters in Zimbabwe is not access to finance and that Zimbabwe’s exports are not competitive in the mining, agricultural and manufacturing sectors. The revealed comparative advantage index was computed to measure the competitiveness of Zimbabwe’s exports.For the qualitative approach, the study used the triangulation method which involved combining and utilising the questionnaire, interviews and focus group discussions. The results from the study indicated that following variables increased export intensity of Zimbabwean SMEs; business ownership, use of export processing zones, export years, firm size, and GDP of trading partner. The following variables have an inverse relationship with the export intensity of Zimbabwean SMEs: gender, distance from trading partner and research & development. The results also indicated that these further variables do not determine the export intensity of SMEs in Zimbabwe: support institutions, years of education, product type, firm age and GDP of Zimbabwe. The major constraint faced by exporting SMEs in Zimbabwe is limited access to finance. Zimbabwe is competitive in the agricultural and mining sector exports, but not in manufacturing sector exports The policy implication of the findings is that SME support needs to go beyond support institutions when it comes to SME export promotion. Further SMEs in the agriculture and mining sectors need to be promoted for export growth since Zimbabwe is competitive in these sectors. However the manufacturing sector cannot be ignored, since many economies have developed due to exports of manufactured products and a country needs to have balanced export growth in both primary and manufacturing sectors. In order to have motivated, career SME exporters, entrepreneurship education should begin from primary school right up to university so as to improve entrepreneurial aspirations, attitudes and behaviour in the long run.

- Description: There is consensus that Small to Medium Enterprises (SME) exports play a critical role in the development of economies. It has been widely acknowledged in empirical research done around the world that small businesses make a significant contribution to economic development, employment, competitiveness and the reduction of regional disparities. However, empirical literature gives conflicting evidence on the determinants of export performance among SMEs. The study contributes towards the debate on SME exports by: (i) investigating the variables that determine export performance among SMEs in Zimbabwe (ii) establishing the competi-tiveness of Zimbabwe’s exports and (iii) ascertaining the major constraints faced by SME ex-porters in Zimbabwe The researcher gathered data from 120 SMEs and 10 institutions in Zimbabwe for the period 2009 to 2015. SME samples were chosen from Harare, Mashonaland Central and Mashonaland East provinces while all 10 of the institutions were chosen from Harare province. Convenient non-probability sampling method was used to select SMEs while stratified sampling technique was applied in the selection of institutions. Both qualitative and quantitative research methods were employed. For the quantitative approach, panel data ordinary least squares method was used in the form of the gravity model of trade. Export intensity (used as a measure of exports) was regressed against support institutions, business ownership, research & development, educational years, use of export processing zones, product type, export years, firm size, firm age, gender, distance from trading partner, Gross Domestic Product (GDP) of trading partner, and GDP of Zimbabwe. The random effects estimation method was used, basing on results from the Durbin-Wu-Hausman test. The null hypothesis was based on the premise that the variables under study do not determine export intensity of SMEs in Zimbabwe. Other null hypothesis were that the major constraint faced by SME exporters in Zimbabwe is not access to finance and that Zimbabwe’s exports are not competitive in the mining, agricultural and manufacturing sectors.

- Description: The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

- Description: In the Cape Colony, and then in South Africa generally, the twentieth century was to see the emergence, growth, and final closure of teacher training colleges. South Africa was one of the few Anglophone countries on the African Continent which, in 2003, did not have a separate and dedicated system of Teacher Education Colleges.1 From the 1920s on, there was a spirited debate over whether primary school teacher training was better achieved in the training college or the university. The publication of the National Education Amendment Act (No 73 of 1969) finally placed all teacher training, primary/elementary and secondary, within University Faculties of Education. The present study investigates the history of the Grahamstown Teacher Training College (GTTC) which was officially recognised in 1894 for the training of young white women. The GTTC was an independent college, founded and owned by an Anglican Religious Community for women, the Community of the Resurrection of Our Lord (CR), but it was also an Aided College of the Cape Education Department. As an Aided College, the GTTC was subject to Government Inspection annually, and the students wrote the official examinations set by the Department of Education. The College was run entirely by women and existed for 81 years. The emphasis in the college was on the practical professional training offered. The focus was on the ‘complete’ education of the student, rather than merely on the content of the curriculum. This study shows that the GTTC more than earned its reputation of being one of the finest training colleges in South Africa and that it was indeed a unique educational development. A feature of particular note was that the college was a trail-blazer, a pioneer in the field of education practices. It was the first college to introduce class music and class singing, the first to employ a physical education teacher, to have a full-time librarian and elocutionist, and it was at the GTTC that the assignment method of study was introduced. All these factors are highlighted in the course of this study.

- Description: The spread of contract farming in South Africa in recent years has provoked an ideological debate in literature. Linking small-scale vegetable farmers with lucrative agricultural markets through agribusiness value chains is seen as one of the foremost emerging agricultural practices to develop the subsistence farming sector into a mainstream economic sector – thereby revitalising the rural economy and alleviating poverty levels in the developing rural areas of South Africa. However, the challenges agribusiness and small-scale farmers experience in contract farming engagement and the prospects for enhancing the inclusion of small-scale farmers into modern value chains remain open to debate – two decades after transition to democracy. Yet the factors and mechanisms influencing the effective application of contract farming in the transition to commercial farming by small-scale farmers have not been thoroughly explored in South African research. Despite the efforts and the substantial investments made and the various policies and initiatives instigated to fast-track the linkages of small-scale farmers into high-value markets, the success stories of previously disadvantaged farmers operating in commercial agri-food chains are rare. Given the millions of small-scale farmers in former homelands alone, the negligible number of small-scale farmers successfully operating in commercial agri-food chains shows that the objectives to enable small-scale farmers to improve their livelihoods through participation in commercial agri-food chains have not yet been met. The broad objectives of the study were therefore to investigate the agribusiness challenges inherent in contract farming and the conditions and incentives required by agribusiness firms to engage small-scale vegetable farmers in contract farming programmes. Furthermore, the study examined the role played by the South African government to reduce the high transaction costs incurred by agribusinesses when engaging small-scale farmers in contractual arrangements. The Amathole and Sarah Baartman (formerly Cacadu) district municipalities in the Eastern Cape Province of South Africa were chosen as the composite survey area for this study. A predominantly qualitative research approach was applied to gather data on the phenomena under study. The following methodologies and research instruments and tools were selected. Firstly – as the secondary component of the research – a systematic review of literature to date was conducted to guide the empirical research and primary methodology. Secondly, the empirical component of the study comprised a questionnaire survey, unstructured interviews and focus group discussions. The questionnaire survey was used to collect data from the agribusiness firms in the area surveyed concerning the following aspects: the significant determinants of contract farming, the incentives required by the agribusiness firms to engage small-scale vegetable farmers in their contract farming programmes and the challenges faced by agribusiness firms in their interaction with small-scale farmers in contractual arrangements. Unstructured interviews were used to gather data from officials at each of the three levels of government – the Department of Rural Development and Land Reform nationally, Department of Agriculture and Land Reform provincially and (at local government level) two district municipalities – on the role played by government to reduce the high transaction costs incurred by agri-firms when procuring agricultural raw materials from small-scale vegetable farmers. Focus group discussions were conducted with small-scale farmers regarding their perspective on working with agribusiness firms and to establish the distinguishing characteristics of small-scale farmers in the area surveyed. Relevant policy documents collected from two of the three representative groups of the study population, i.e. agribusiness personnel and government officials, provided the essential context. The study revealed a limited number of contract farming business linkages between small-scale vegetable farmers and agribusiness firms in the survey area. Those that do exist are problematic to both the agribusiness firms and the small-scale farmers. It emerged that the contract farming environment in the area surveyed is highly polarised and characterised by a fundamental conflict of interest between agribusiness and farmer. Among the divergent key factors inhibiting contract farming engagement were a lack in terms of quality seeds, trust, entrepreneurial skills and formal contract agreements. Asset endowment (both land and non-land assets) was found to be significant pre-selection determinants in the farmer’s capacity to be contracted. Access to innovative technology, as well as government incentives such as production inputs, were found to be critical to agribusiness firms to engage smallscale farmers in their contract farming programmes. Government assistance in terms of high transaction costs to agribusiness firms working with large groups of small-scale farmers was found to be essential but inadequate under current policy. This impacts directly on the effectiveness and promotion of contract farming. Furthermore, the current results corroborate the findings of numerous South African studies in the vast body of worldwide research. Firstly, lack of land and non-land assets continue to be major impediments to the direct participa-tion of small-scale farmers in contract farming programmes and, secondly, the transaction and market information costs incurred by agribusiness prevent the participation of less endowed farmers in contract farming programmes. Conducted within the interpretivist paradigm, the explorative research identified wide-ranging challenges in the relationship between agri-business and small-scale farmers which directly impact the effective-ness of contract farming as a development and agrarian reform strategy. Despite their problematic relationship, however, agribusiness and small-scale contract farmers were in agreement that the government needs to expand its support for agri-firms to incentivise greater numbers of small-scale farmers having the opportunity to achieve commercial status through contract farming. The study therefore recommends a collaborative partnership between private firms and government, with state support through revised policies and development programmes. These amendments are crucial to enhancing the engagement of small-scale vegetable farmers in lucrative agri-food chains.

- Description: The major contributions of this thesis are addressing the need for an objective quality evaluation of a transcription factor binding model, demonstrating the value of the tools developed to this end and elucidating how in vitro and in vivo information can be utilized to improve TF binding specificity models. Accurate elucidation of TF binding specificity remains an ongoing challenge in gene regulatory research. Several in vitro and in vivo experimental techniques have been developed followed by a proliferation of algorithms, and ultimately, the binding models. This increase led to a choice problem for the end users: which tools to use, and which is the most accurate model for a given TF? Therefore, the first section of this thesis investigates the motif assessment problem: how scoring functions, choice and processing of benchmark data, and statistics used in evaluation affect motif ranking. This analysis revealed that TF motif quality assessment requires a systematic comparative analysis, and that scoring functions used have a TF-specific effect on motif ranking. These results advised the design of a Motif Assessment and Ranking Suite MARS, supported by PBM and ChIP-seq benchmark data and an extensive collection of PWM motifs. MARS implements consistency, enrichment, and scoring and classification-based motif evaluation algorithms. Transcription factor binding is also influenced and determined by contextual factors: chromatin accessibility, competition or cooperation with other TFs, cell line or condition specificity, binding locality (e.g. proximity to transcription start sites) and the shape of the binding site (DNA-shape). In vitro techniques do not capture such context; therefore, this thesis also combines PBM and DNase-seq data using a comparative k-mer enrichment approach that compares open chromatin with genome-wide prevalence, achieving a modest performance improvement when benchmarked on ChIP-seq data. Finally, since statistical and probabilistic methods cannot capture all the information that determine binding, a machine learning approach (XGBooost) was implemented to investigate how the features contribute to TF specificity and occupancy. This combinatorial approach improves the predictive ability of TF specificity models with the most predictive feature being chromatin accessibility, while the DNA-shape and conservation information all significantly improve on the baseline model of k-mer and DNase data. The results and the tools introduced in this thesis are useful for systematic comparative analysis (via MARS) and a combinatorial approach to modelling TF binding specificity, including appropriate feature engineering practices for machine learning modelling.

- Description: Psychobiography can be viewed as the re-writing of an individual‟s life story previously undetected. In general, it consists of a combination of two central elements: biography and psychological theory, which aim to explain the particular individual‟s psychological development. This particular study serves to explore the extraordinary life of renowned singer and songwriter, Ian Kevin Curtis (1956-1980), who died by suicide at the early age of 23. The basis for this investigation will take the form of notable biographical accounts of the subject‟s life, together with the application of Thomas Joiner‟s (2005) interpersonal-psychological theory of suicide which identifies factors that lead to suicidal ideation - in an attempt to understand the psychological circumstances that contributed to Curtis‟s suicide. In doing so, Adler‟s (1929) theory of Individual Psychology was applied to the life of Curtis in an attempt to build on Joiner‟s theory. This led to the concept of control being introduced and contributed to the development of an intake form to identify those at risk for suicide. It is hoped that exploring the psychological circumstances that contributed to Curtis‟s suicide and their interpretation by the subject will bring about an understanding of the risk factors that may induce suicide and, by extension, will highlight the relevance of this psychobiographical study as a tool for investigating and promoting preventative measures concerning suicide. The psychobiographical data collection and analysis for this research thesis will be guided by Yin‟s (2003) theory of „analytic generalisation‟ which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organising and integrating that data, and Alexander‟s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience.

- Description: Against the background of a re-emphasis of human rights, social justice and democracy, learner leadership has become a topic of interest and importance. An absence of any meaningful form of leadership development among learners in formerly disadvantaged schools in South Africa prompted this interest into exploring the development of learner leadership. A more recent approach to learner leadership in many countries, including South Africa, has been to look at providing the necessary platform for learners to experience a more shared, cooperative, transformative and service approach within schools in order for them to develop their capacity to lead. This is supported by theoretical developments in the field of leadership, such as Distributive Leadership and Servant Leadership, which emphasise shared leadership. These developments were based on dialogue and strong relationships, where learner leaders situated their practices in moral action, with signs of individual growth, social justice and democratic positioning. In spite of this, not much is known of learner leadership development in South Africa. There are very few studies, none using approaches which look at the context and situation holistically. Hence this study, using Cultural Historical Activity Theory and Critical Realism as under-labourer, for its stance on ontological, epistemological and principled expectations of reality and its understandings on agency and structure, is advanced. Transformational leadership theories, in particular Distributive and Servant Leadership, are used as lenses to help make sense of the nature of learner leaders’ practice and the development of leadership. The aim of the single case study was to discover and explore how and under what circumstances learner leadership could be developed. To this end the researcher established a leadership development group at a previously disadvantaged secondary school. This project provided the platform for leadership development initiatives and became the activity which is the focus of this research. The study examines how leadership is learned and practised, and how the participants interrelate and influence learning and practice in their activity system. It examines the challenges that the learner leaders faced within their communities and what the underlying causes of these challenges were. Qualitative semi-structured interviews, document analysis, direct observation and focus groups were used to collect data. Non-probability sampling, in particular purposive sampling, was used in selecting the sixteen learner leader volunteers who participated in the study. These learners represented various ages, gender and leadership positions that were held in the school. Using inductive, abductive and retroductive modes of inference, the data was abstracted and analysed. The Change Laboratory workshop was used to boost the growth of shared collective views of the learner leaders within the changing object and activity system, in order to build and develop new practices, tools and models. The study recognized that learner leadership was generated by numerous mechanisms, which included the need to overcome the calamitous scarcity of virtuous leadership within their communities; the need to address cultural and historical assumptions, prejudices, and values that existed which reinforced their existing perceptions and behaviour towards leadership; the need to create a space for learner leaders to share responsibilities, thoughts, and become reciprocally dependent on each other, developing together due to their cooperative efforts; the need to demonstrate a willingness and the necessary resilience to survive in an environment whose socioeconomic demands and effects are restrictive and disempowering; a need to respond to the demand for impartiality and access to leadership; and a need to know that one is able to transform the practice of leadership, without it necessarily affecting one’s culture, in such a way that the needs of the people are met. This thesis reports on encouraging signs of leadership growth within the activity, observed and documented over a period of three years. The intervention led to behaviour and attitudinal development that suggests transformative learning and agency. The study’s findings further clarify the many challenges the potential learner leaders faced. Chief among these was the lack of adequate and efficient structures and systems in their communities in order for effective leadership to be established and practised in their communities. These included weak social structures in homes that were unable to support and meet the needs of the learner leaders due to the breakdown of families. Negative forces included high levels of authoritarian leadership practised by a restrictive socialised patriarchy. The underlying causes of these challenges include the perceived threat to individual dignity and survival; the fear of change; the feeling of powerlessness; a lack of hope which fuelled an apathy, a low self-esteem and poor attitude to education; adverse socioeconomic conditions; poor communication skills; a lack of adult role models and willpower; the demand for impartiality and access to leadership knowledge. In order to encourage learner leaders to advance their practice of leadership, the study recommends that adolescents be made to feel valued and included in the development process of leadership so that their willingness to engage with the process becomes pre-emptive. Learner leaders prefer structure, so it becomes all the more important to ensure that any rules, policies and guidelines that are established exhibit a demonstration of transparency and accountability. The study also recommends that when developing an understanding of the learner leaders’ behaviour, using their socio-cultural and historical contexts, they are provided with a non-threatening platform. This enables them to become empowered to actively participate, debate and dialogue collaboratively. They have an opportunity to demonstrate a willingness to engage with each other over tensions that arise, breaking the bonds of socialized pathology.

- Description: The use of genetically modified (GM) maize technology is subject to compliance with stewardship requirements and the adoption of specific management practices that promote the long-term effectiveness and environmental sustainability of the technology. For smallholders to comply with these requirements and adopt the desired management practices to ultimately benefit from the technology, they require information that creates awareness of the value of these requirements. To determine what information farmers receive about GM maize and how this information is disseminated to farmers, face to face interviews were conducted with 81 extension personnel and 210 smallhoder GM maize farmers in the Eastern Cape Province of South Africa. The effect of Bt maize introduction and management practices in smallholder maize agroecosystems in the Eastern Cape on Bt maize target [Busseola fusca (Fuller) (Lepidoptera: Noctuidae)] and non-target insect pests [Agrotis segetum (Denis & Schiffermüller) (Lepidoptera: Noctuidae), Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)] and a snail species, [Cornu aspersum (Müller) (Gastropoda: Helicidae)] was determined through laboratory, field and cage experiments. The effect of smallhoder farmers‟ GM maize cultivation practices on the profitability of GM maize technology was also determined through on-farm trials in different localities of the Eastern Cape identified as hot-spots for stem borer and weed infestation. Results of surveys indicated that extension personnel had a low level of awareness of GM maize technology stewardship requirements. GM maize technology was also largely disseminated to smallholder farmers through non-participatory approaches and print media sourced from GM seed companies. Although farmers had a high level of contact with extension services, they lacked access to information about GM maize technology. Smallholder farmers‟ level of awareness about GM maize and compliance with the requirement for the planting of non-Bt maize refuge areas adjacent to Bt maize was also very low. While Bt maize event (MON810) commonly cultivated by smallholder farmers in the Eastern Cape Province had a variable effect on A. segetum under laboratory conditions, it had no effect on the incidence of plants damaged by A. segetum and C. aspersum under field conditions. The incidence of H. armigera damage on Bt maize plants was however significantly affected by Bt maize. Populations of B. fusca collected from smallholder maize fields in the province were observed to be still highly susceptible to Bt maize. Results of on-farm evaluation of the profitability of GM maize revealed that stem borer pressure, growing conditions, input supplies and market access affect the productivity and profitability of GM maize cultivation. Challenges within the extension and advisory services of the Eastern Cape which can militate against smallholder farmers‟ ability to benefit from GM maize technology and sustain the long-term efficacy of the technology were identified during this study. Given these challenges and the fact that the cultivation of GM maize may not be profitable under typical smallholder maize cultivation conditions and management practices, dissemination approaches that provide farmers the opportunity to evaluate GM maize technology alongside alternate technologies under their conditions, may prove beneficial.

- Description: As a potential main player in the primary health care sector and the impending National Health Insurance (NHI), community pharmacists could make a significant contribution to easing the health care burden in South Africa. Recent legislative and organizational changes related to the corporatization of pharmacy in South Africa have impacted significantly on the profession and stand to weaken the already ‘tenuous’ professional identity of pharmacists in the country. Since community pharmacists are viewed as potential main players in the primary health care sector, the influence of corporatization on pharmacists’ identities and their concomitant ability to contribute to easing the health care burden in South Africa need to be considered. In this regard, this study examined the influence that corporatization has had on the professional identity of community pharmacists practicing in the Nelson Mandela Bay area of South Africa. That is, in an effort to understand the influence that corporatization has had on changing professional identities and practices the attitudes, beliefs, and behaviours of community pharmacists regarding the philosophy and practice of pharmacy were explored. This included ascertaining community pharmacists’ self-perception of their professional identity and the perception of users of these community pharmacies. The study was conducted from an interpretative epistemological paradigm, based on a philosophy of pragmatism. Data collection was conducted in two phases and a qualitative approach, which included in-depth and semi-structured interviews, was adopted as a design. Phase one investigated the self-perceptions of sixteen community pharmacists, equally distributed between independent and corporate pharmacies in the Nelson Mandela Bay (NMB). Phase two examined the perceptions of thirty-two end-users of the pharmacies included in the study. Data from both phases were then analysed and interpreted. Following the identification of seven core professional identities, namely pharmacists as custodian or keeper of medicines; primary health care givers; confidante and carer; jaded; astute and credible; corporate; and independent, it was determined that corporatization has, to various degrees, had an effect on the undermining of Nelson Mandela Bay community pharmacists’ view of themselves as skilled professionals in the health care sector. In short, it was found that corporatization is believed to have blurred the boundaries related to what it means to be a pharmacist and what role pharmacists should play in the provision of public health care. Corporatization does not appear to have influenced the patients’ or pharmacy end-users’ perceptions of the pharmacist, and furthermore does not play a major role in their choice of pharmacy. It is the perception of pharmacists in this study that with the introduction of legislative changes, more so corporatization, they experienced an undermining of their professional skill and disregard for costs involved in becoming a pharmacist. The perceived undermining of the professional skill of pharmacists threatens the valuable contribution that community pharmacists can make to balancing the country’s socio-economic status by appropriately and efficiently assisting in preventing, managing and/or reducing the disease burden in South Africa. Corporatization of the community pharmacy sector seems to have realized the government’s intention of making medication affordable to its citizens, however, the certainty of whether corporatization benefits patients that are in need of access remains to be seen. Community pharmacists could in fact, capitalize on the identification and enactment of their clinical skill (pharmaceutical and social caregiving) as this skill appears to be a tool that will allow pharmacists meaningful transition to being real contributors of primary health care in the imminent introduction of the NHI. At the same time, recognition of the role a pharmacist plays in primary health care will be supporting the government in its endeavours to making medicine accessible and affordable to all South African citizens without compromising their health needs. Ultimately, pharmacists can assist in the balancing and/or improvement of the socio-economic status of our society and the country.

- Description: Kuqikelelwa ukuba kukho amaXhosa (amaMfengu) angcambu zawo ziseMzantsi Afrika amalunga namakhulu amabini amawaka azinze eZimbabwe ukususela kwiminyaka yoo-18001900. Uninzi lwawo lufumaneka eMbembesi, eFort Rixon, eFilabusi, eKenilworth naseMotapa eBubi. Imbali ithi, inxalenye yala maXhosa ngawaseMpuma Kapa, afudukela eZimbabwe noCecil John Rhodes eqhuba iinqwelo kananjalo esebenzela uRhodes ngeminyaka yoo-1800. Le thisisi yongeza kulwazi olutsha malunga nala maXhosa aseZimbabwe, iphonononga ubume bolwimi, imbali nemvelaphi yala maXhosa azinze eZimbabwe lo gama ibonisa ukuba naphantsi kwayiphi na imeko, ulwimi luyakwazi ukuphila ngaphaya kwemida. Ulwimi nenkcubeko zingumtya nethunga, ngenxa yoko le thisisi yayame kakhulu kwinkcubeko. Iethinografi nembali yomlomo zisetyenziswe njengendlela okanye imethodi yokuqhuba olu phando. Iziphumo zolu phando zibonisa ukuba umhlaba, inkcubeko, iingoma, inkolo yobuKrestu, iincwadi ezingaphelelwa xesha zoncwadi lwesiXhosa, iteknoloji namakhasi onxibelelwano nomgaqo-siseko waseZimbabwe (2013) zibe zizixhobo ezidlale indima ebonakalayo ekulondolozeni nasekuphuhliseni isiXhosa eZimbabwe. Imiba ephathelele kumgaqo-nkqubo wesiXhosa eZimbabwe nayo iyaphononongwa, njengokuba isiXhosa ilulwimi oluthathwa njengolusesikweni eZimbabwe.Kusetyenziswa iithiyori ngeethiyori ezingobuni, kuquka nethiyori kaCollier (1997) apho abona ubuni njengolunamacala amabini; avowal kunye ne-ascription. Ubuni bamaXhosa aseZimbabwe buxoxwe ngokwayama kwi-avowal njengokuba uCollier (Ibid.) eyicacisa. Kwizindululo eziqulathwe kolu phando, kuboniswa ukuba ikho imfuneko yokuba iintsapho zaseZimbabwe zidityaniswe nezizalwane zazo eziseMzantsi Afrika. Ukufundiswa kwesiXhosa kwaneenzame zokusebenzisa isiXhosa njengolwimi lokufunda nokufundisa kwizikolo zamaXhosa ezikumabanga aphantsi kuyafuneka nako ukuba kuphandwe nzulu. , There are an estimated two hundred thousand South African amaXhosa who are mostly amaMfengu descendants living in Zimbabwe since the late 1800s-1900s. The majority are found in the areas of Mbembesi, Fort Rixon in Filabusi, Kenilworth and the Motapa area in Bubi. It is stated that some of the amaXhosa living in Zimbabwe came from the Eastern Cape with Cecil John Rhodes as domestic workers and on wagons during the 1800s. Therefore, this thesis provides new knowledge about amaXhosa living in Zimbabwe and gives an analysis of the sociolinguistic and historical background of the amaXhosa living in Zimbabwe while showing how a cross-border language can survive against all odds. The subject of culture has been dealt with as there is a reciprocal relationship between language and culture. Ethnography and Oral History have been used as methods for this research. The findings reveal that land, culture, songs, religion, South African Xhosa literature classic books, technology and social media, as well as the 2013 Zimbabwean constitution, are tools that have played a role in the survival and maintenance of isiXhosa in Zimbabwe. It also assesses Language Policy issues as isiXhosa is now an officially recognized language in Zimbabwe. Drawing on various theories on identity, including Collier’s (1997) understanding that identity is divided into avowal and ascription, the identity of the amaXhosa of Zimbabwe has been discussed in this thesis with an emphasis on avowal as discussed by Collier (Ibid.). Among other recommendations, this study further recommends that a research that looks at the reunion of the Zimbabwean amaXhosa with their South African relatives needs to be undertaken. It also recommends that the teaching of isiXhosa as well as attempts to make isiXhosa the Language of Learning and Teaching (LoLT) in the amaXhosa primary schools and pre-schools also needs to be researched further.

The findings reveal that land, culture, songs, religion, South African Xhosa literature classic books, technology and social media, as well as the 2013 Zimbabwean constitution, are tools that have played a role in the survival and maintenance of isiXhosa in Zimbabwe. It also assesses Language Policy issues as isiXhosa is now an officially recognized language in Zimbabwe. Drawing on various theories on identity, including Collier’s (1997) understanding that identity is divided into avowal and ascription, the identity of the amaXhosa of Zimbabwe has been discussed in this thesis with an emphasis on avowal as discussed by Collier (Ibid.). Among other recommendations, this study further recommends that a research that looks at the reunion of the Zimbabwean amaXhosa with their South African relatives needs to be undertaken. It also recommends that the teaching of isiXhosa as well as attempts to make isiXhosa the Language of Learning and Teaching (LoLT) in the amaXhosa primary schools and pre-schools also needs to be researched further.

- Description: Amathole District Municipality has for the past five consecutive years been receiving an unqualified audit opinion from the AGSA. This has been the trend, despite the commitment made by the Executive Mayor in April 2012 to the then Auditor-General, Mr Nombembe, that the leadership of the municipality would deliver a clean audit outcome by 30 June 2013. This scenario is replicated in the local municipalities within the district. Two of the district municipalities have for the past three consecutive years been receiving a disclaimer audit opinion. In one of the municipalities, this trend changed; and this municipality received an unqualified audit opinion for two consecutive years; while in the third year, it received a qualified audit opinion. The stagnation and regression in the audit outcomes of these municipalities may be as a result of either the non-implementation of audit-action plans to address the previous year’s audit findings; or there could be other factors resulting in the above scenario. The main objective of this study is to investigate whether the utilisation of the Auditor-General’s reports improve the audit outcomes in selected municipalities within Amathole District Municipality for the period 01 July 2006 to 30 June 2015.

- Description: This study focussed on the evaluation of the implementation of the South African Police Service sector policing in the Eastern Cape province of South Africa. A mixed methods approach was used to gather, collect and analyse data for this study. The data were collected through semi-structured in-depth interviews, focus groups discussions and a survey. The quantitative approach dominated in data collection, whilst the qualitative approach was used to corroborate the quantitative findings. For the quantitative approach, 265 questionnaires were administered to 121 volunteer participants targeting the station commanders, cluster commanders and sector commanders. A hundred and forty questionnaires were also administered to the Sector Crime Forum chairpersons who were selected using simple random sampling from 32 police stations. The sector commanders were used for in depth interviews. The rationale behind was that the sector commanders are playing a key role in the implementation of sector policing. Simple random sampling was used to select the participants. The study area was in the Eastern Cape, where the research sample and participants were drawn. The findings of the study indicated that although sector policing minimum standards have been achieved by many stations, the study found out that there are some stations that have not yet attained the policy goals in terms of optimal implementation of sector policing in the Eastern Cape Province. The study established that the farm and rural and remote police stations were not complying with the minimum standards laid down in the National Instruction 3/2009. The problem of non-compliance emanates from the shortages of resources. Further findings on this study were based on the experiences and challenges of the implementers of sector policing. The study found that there were challenges confronted by them in the implementation process. Although some of the participants were indicating their enjoying working closely with their communities, there were some major challenges that they experienced in the process of executing their duties. The results of the study indicate that resources were not adequate to ensure that this new policing strategy is properly executed. Another important finding which was identified by the study was the fact that sector policing, as a new policing strategy, was not adequately communicated and marketed for it to be accepted and to for it to achieve the necessary buy in from stakeholders. The study further established that training, development and capacity building were lacking to capacitate the implementers of the new policing strategy. Further, sector to sector collaboration was identified as another challenge by the study. Team work was very much limited. The study further revealed that command and control was not enhanced by the sector commanders in their sectors. The sector patrol reports were not available in the files and AVL reports were also not retrieved and monitored. The factors highlighted above have a negative bearing on the reduction of crime. Poor police visibility and stakeholder participation in crime prevention programmes are not reducing crime.

- Description: The arena for finding an intimate partner has changed significantly in the 21st century with online love relationships becoming more prevalent. Research indicates that individuals do experience meaningful online romantic love relationships and that these relationships often lead to face to face (FTF) relationships. However, limited research has been done on exploring the experiences of those who are/were involved in online romantic love relationships. Furthermore, research conducted on online love romantic relationships generally fails to investigate how people experience passion online, hereby ignoring this integral component of romantic love. The primary aim of the research study was to explore young adults’ experiences of romantic love relationships in virtual space. More specifically, the study explored how young adults experienced intimacy and passion as elements of romantic love online. The study was viewed from an interpretative paradigm and made use of a qualitative approach. The researcher conducted in-depth, semi-structured interviews with seven participants which were transcribed, and analysed using Interpretative Phenomenological Analysis (IPA). Four superordinate themes were identified, namely, Online Intimacy, Online Romance and Passion, Online Love, and Social Exchange Online. The participants experienced romantic love online and reported that these relationships were very significant, real and impacted on their psychological well-being. The study created a heuristic base that will provide impetus for this emerging field in research.

- Description: The study sought to investigate academic support policies and strategies for underperforming students at Limpopo universities. By focusing on the University of Venda and that of Limpopo (which are located in rural settings), this study will contribute to the body of knowledge addressing the learning needs of underperforming students in resource constrained universities in South Africa. Qualitative research methodology was considered most appropriate in the present study. The researcher used various research instruments as the fact finding strategies. These comprised tools for data collection. The researcher used questionnaires and the survey of secondary sources for data collection. The researcher chose these instruments because this also means discussing the advantages of using questionnaires and reading, for example gaining an in-depth perspective regarding the actual experiences of students who underperform in their studies. The study focused on first year underperforming students, academic support policies and academic support programmes. Permission was sought from the two universities’ Research Departments to conduct this study. Once permission was granted, the questionnaire was sent out to prospective participants. In addition, the researcher involved intra-group despondence analysis. Since the bulk of the data from the questionnaires was qualitative, thematic analysis was utilised. This involved identifying patterns and emerging themes out of the differences and similarities from the despondences’ views. This study was conducted in the Limpopo Province, South Africa, where the two universities are situated.The study population were students, academics, Information Management Officer, CHETL staff and relevant personnel at the Limpopo.

A narrative, child-participatory study of domestic mobility within grandmother-headed households in the Eastern Cape, South Africa

- Description: The movement of adults and children between households in South Africa is a tradition entrenched by apartheid state policies and fuelled by poverty and HIV/AIDS. Children affected by domestic mobility include not only orphans, but those whose families are struggling financially or are deprived of income through illness or death. One example of domestic mobility is the redistribution of children through grandmother-headed households. While domestic mobility has been researched from a number of different academic perspectives, there is scanty psychological literature on the subject, and a gap around children’s experiences of their own mobility. Children’s roles and agency in their mobility, and how these are shaped by their environments, social relations and resilience, are not considered. This research aimed to explore the meanings that domestic mobility had in the lives, identity constructions and personal narratives of South African children currently residing in grandmother-headed households in the Eastern Cape. This was achieved through a narrative approach, interested in big life-stories, as well as small stories of everyday interaction. Over the course of two years, five child participants aged between eight and 12 years constructed narrative material through participatory action research methodologies, including the mapping of time-lines and their lived environments, and photovoice. Child participants and their families were selected from the client-base of a non-governmental organisation, Isibindi (Alice). Narratives were analysed as case studies to tell detailed stories of children’s lives, and to comment on issues associated with domestic mobility, socio-economic status, gender, education, HIV/AIDS and social protection. The study found that blanket definitions of poverty and domestic mobility conceal important variations in levels of poverty and individual experiences of mobility. While children are excluded from processes of decision-making about their mobility, they perform their agency by contributing to household survival and ensuring the continuation of mutually beneficial attachment relationships. This research argues that interventions which act on various systemic levels (macro, meso and exo) add support and protection for vulnerable children. This research also argues for psychological “scaffolding” of potentially traumatic or precarious processes, such as domestic mobility and deaths in families, through caregivers preparing and consulting with children before events happen.

- Description: The motivation for this study originated from the problem of children who are being neglected after they have given evidence in the court of law. The researcher also noticed that when children were giving evidence, some were still showing signs of trauma and were crying throughout the proceedings. The researcher became aware that most of the children were never referred to social service professionals for counselling and after care services. The goal of the research was to explore the psycho-social effects of court verdicts on children as rape victims. The aim of the study was to determine the effects, challenges, emotional development and consequences, experience and reactions of rape and sexually assaulted child victims after the court verdict has been adjudicated. This was a case study of the Queenstown Area, Eastern Cape, South Africa. The purpose was to identify gaps as there are minimal services rendered to rape victims after the court verdict has been adjudicated in the South African context so as to formulate strategies that can be framed in order to work effectively with the victims and their immediate families. In order to reach the research goal, the following objectives were presented: To examine the after-effects of rape to children as victims of rape. To investigate the challenges the victims of rape are facing in their communities. To investigate the impact of giving evidence in the court of law by children who are victims of rape. To examine the after-effects of court verdicts on children who are victims of rape. To establish the kind of support provided to children by social networks after they have given evidence in the court of law. To investigate the kind of support provided by social service as well as legal professionals to children as victims of rape. In order to meet the objectives of the study, interviews were conducted to 30 victims of rape (both boys and girls) and data were analyzed according to the qualitative data – analysis procedures. The researcher also conducted literature review on core concepts (such as victims, rape and the legal perspectives of rape) pertaining to the topic under study in order to refer the findings of the study to literature. The researcher utilized the grounded theory research design. The research domain where the interviews took place was at the Queenstown Area under the Department of Justice and Constitutional Development magistrate jurisdiction (McBride, Lesseyton, Mlungisi Township, Komani Township, Molteno, Sterkstroom Dordrecht and Indwe). In this study, 30 Xhosa speaking children of different ages, gender, educational standards, socio-economic backgrounds as well as those who suffered different types of rape, as defined by the Sexual Related Matters Act 32 of 2007; they were all interviewed through use of a semi-structured interview schedule. The respondents were selected with the help of the Department of Justice and Constitutional development as well as South African Police Services (SAPS) based on their suitability to provide information rich data. The interviews were audio-taped and transcribed verbatim. The data were analyzed according to the grounded theory analysis procedures. The following conclusions regarding the study were made: There is lack of implementation of Children’s Rights by professionals working with victims of rape. Children were never informed about the sentences imposed to the offenders. Focus group (professionals) participants acknowledged the fact that there is no compensation given to victims in a South African court of Law. Registering the offender is not benefitting the victim as the offender is sometimes appealing the judgement and sentencing. There are no adequate services rendered by social services professionals to rape victims, especially children. In most cases, they were never referred to any professionals for services following the rape incident. There are no aftercare services for children after giving evidence in the court of law. Children as victims of rape as well as their immediate families must be continuously referred to specialist to get therapeutic services. There is lack of forensic professionals working with children as victims of rape in Eastern Cape. Children as victims of rape are secondary victimized by relatives of the perpetrators after the sentence has been adjudicated. When there is no support provided by family members, victims are more likely to drop out of school. Members of the community lack information on the concept rape, and knowledge that everybody in South Africa can be raped.
