- Description: Increasing expansion, population and urbanization have resulted in high volume of waste generated daily in South Africa. Most municipalities in the Eastern Cape are experiencing challenges in effective waste disposal, thus resulting in pollution of the air, soil and groundwater by the percolation of harmful contaminants into the environment from landfill leachate. Groundwater resources are limited in South Africa due to itssemi-arid nature. Also, there islimited information available, not only about where it occurs but how to manage it so that its quality does not depreciate to unacceptable levels. A combination of these factors coupled with a gap between waste policy and its subsequent implementation may be disastrous to South Africa. This research examines the impact of landfill sites on groundwater resources at three selected sites in the Eastern Cape Province using an integrated geological and geophysical approach. The methodology adopted include: an exhaustive literature review on waste management policies and practices in South Africa and Eastern Cape specifically. It also involved remote sensing for the study of geomorphology and structural interpretations of lineaments. Field excursions, analysis of physico-chemical and geochemical properties of groundwater obtained from monitoring boreholes and leachate pond in the vicinity of the landfill sites was also carried out. Combined induced polarization (IP) and electrical resistivity measurements for geophysical assessment of groundwater vulnerability and petrographical analysis was alos adopted. Data analysis and interpretation of the obtained results showed that the selected landfill sites are generally characterized by a 4-layer Earth structure with an average depth to top of the bedrock between 15 m - 30 m. Plant-rock association observed from the aerial photo-interpretation showed groundwater potential around the locality of the landfill sites with a dendritic to poorly drained x patterns and moderate to high topography. Structural controls such as the presence of lineaments and a fractured bedrock beneath, which are excellent pathways for the migration of leachate, particularly at the Berlin and King Williams Town landfill sites were observed. Analysis of physico-chemical and geochemical properties of water samples showed contamination of the groundwater by heavy metals and some of the physico-chemical properties were above the generally acceptable limits (WHO). These include high electrical conductivity (EC) and total dissolved solid (TDS) values observed in the groundwater samples from the King Williams Town landfill which indicated a downward transfer of leachate into the groundwater. The difference in EC and TDS values for boreholes BH2 and BH1 (9892 µS/cm, 4939 mg/L and 6988 µS/cm, 3497 mg/L respectively), showed that concentration of contaminants increased towards the centre of the landfill. Interpretation of the obtained results from the Berlin landfill showed the presence of heavy metals in groundwater samples in high concentrations. This indicated the dumping of toxic and hazardous waste substances on the landfill, contrary to the landfill design and classification. This could have harmful effect on plants and animals. Integrated geophysical assessment showed the presence of leachate plumes on pseudosections across the landfill sites. This was further corroborated on the chargeability pseudosections. Resistivity and IP pseudosections from the Berlin landfill showed a 4-layered Earth structure and anomalous zones of resistivity (≤ 112 Ώ-m) and low chargeability (≤1.25 ms) in the top layers. This is indicative of percolating leachate plume in the unsaturated zone. Contaminants ranging from unsaturated waste with high ion content to dense aqueous phase liquid contaminants, characterized by low resistivity (34 Ώm to 80 Ώ-m) and low chargeability values (0.05 ms to 5.75 ms) were identified across the Alice landfill. Results from the King Williams Town Landfill revealed plume contamination to a depth of about 75 m, well within the aquiferous zone. xi It is suggested that waste disposal practices should be improved by proper waste inspection and classification at landfills prior to disposal, use of lining and cap material to prevent leaching of contaminants into the groundwater below and the construction of waste cells and containment structures. This will go a long way in mitigating groundwater contamination due to landfilling at the study areas

- Description: South Africa democratised in 1994. However, due to the discriminatory and segregationist character of the preceding regime, vast swathes of the country’s spaces and people entered the democratic period heavily deprived of essential government services. This was the case with health care in general, including maternal health care. There were also little to no national data available on maternal deaths, especially among the black population. One of the first tasks of the new National Department of Health (NDoH) was to target the high maternal mortality rate. The NDoH made maternal deaths notifiable by law and instituted auditing and information gathering systems in the health sector; health infrastructure was expanded exponentially, and maternal health care was made free. Despite this, the last 24 years have seen the maternal mortality escalate. The latest statistics show that between 1200 and 1300 women die in the South African public health sector each year during pregnancy and the puerperium. This puts the current institutional maternal mortality rate (MMR) at around 154/100 000 live births. The international target for ‘developing’ countries was to reduce the MMR rate by three quarters by 2015, which would have meant a reduction to 38/100 000 live births. The aim of this dissertation is to examine how the democratic South African government (influenced heavily by global health thinking) has laboured to reduce that statistic. I analyse, using Foucauldian discourse analysis, all relevant health and maternal health policies, procedural documents and reports produced by and for the NDoH in the last 24 years. I draw on Foucauldian concepts, specifically those related to Foucault’s work on governmentality. In this dissertation I introduce a new perspective towards the maternal health practices implemented in South Africa, practices that have generally remained unquestioned, been perceived as self-evident, and thus often escaping critical analysis. Through an analysis of the intended operation of the public antenatal clinic (within the larger institutional system) I show how ‘development’ has come to operate as a truth regime in South Africa – facilitating the introduction of liberal governmentality (including some advanced liberal practices) into public health service provision.

- Description: While South Africa has recently joined the rest of the world in the race to achieve an AIDS free generation by the year of 2030, little has been done to develop the scientific interventions that address HIV-related stigma, which is one of the major barriers to the fight against HIV. To the researcher’s knowledge, this is the first study in the South African context that seeks to assess the forms of HIV- related stigma in a local context and in a rural area in particular, where HIV related stigma research and interventions remains scant. This study acknowledges the dynamic, unique, multidimensional and sensitive nature of HIV-related stigma and, therefore, an explanatory mixed approach enabled the researcher to provide a comprehensive assessment of HIV-related stigma amongst the citrus farm workers who are based in Addo, Eastern Cape. Quantitative data was collected from 200 participants across five farms, whereas 50 employees across the 5 farms were also selected to take part in the focus group discussions. An assessment of the reliability and validity of local HIV-related stigma scales (Kalichman et al., 2005 personal stigma scale-English, isiXhosa and Afrikaans version and Visser et al. 2008 personal and attributed stigma scale-English version) and the UNAIDS (2012) HIV knowledge scale was conducted. The assessment showed that the reliability of these scales of measurement tend to vary according to context. In this study, the Kalichman et al., (2005) personal stigma scale (English version) scored a weaker reliability score (alpha=0.58). Thus, as the scale is not reliable for the rural context, it was not considered. Furthermore, quantitative findings show that citrus farm workers are characterised by lack of/ little knowledge about HIV, which results in the stigmatisation of people who are HIV positive in the form of symbolic, instrumental, personal and attributed stigma, as well as a fear of HIV disclosure. Findings also revealed that participants who display a high personal stigma score are likely to display a high attributed stigma score (r=0.47, p<0.00). This confirm the assumption of social identity theory that people tend to use stigma as a ‘protective function’ to protect their identity by labelling other people as ‘’deviant’ or ‘stigmatising’. This finding is particularly relevant in that it reveals that, while many people are aware that stigmatising people with HIV is not morally acceptable, they rather attribute stigmatising attitudes to their communities. Thus future studies need to consider emphasising the assessment of attributed stigma in a rural context. Quantitative findings also revealed that the effect of the following demographic variables, namely race (F=20.1, p=0.00), marital status (F=3.58, p=0.00), religion (F=7.17, p=0.03) and education (F=2.63, p=0.03) on HIV-related stigma was statistically significant. This provides proof that HIV-related interventions that were developed for the Addo community need to consider the above-mentioned demographics variables. The qualitative findings provided an in-depth analysis of the key quantitative findings. A lack of knowledge about HIV among participants was further confirmed by the following themes that were common during focus group discussions: misconceptions about HIV transmission and prevention; false beliefs that healthy looking people cannot have HIV; HIV symptoms are clearly visible; and HIV can be transmitted through contact with people who are HIV positive. Possible causes of HIV-related stigma as revealed by the qualitative findings include; fear of death; the belief that HIV is a punishment for bad behaviour; and the fear of being isolated and rejected. The qualitative approach revealed other forms of HIV-related stigma that were not common in the quantitative studynamely; healthcare, employment and verbal stigma. The focus group discussions revealed the major reasons why a large number of the farm works may be reluctant to disclose their status, namely fear of the unknown and attributed stigma. The study concluded by offering recommendations for the designing and tailoring of HIV-related interventions in the rural context and in the citrus sector in particular.

- Description: Orientation: The research was a reflection on the careers of senior human resources (HR) personnel registered with the SABPP as master or chartered human resources practitioners. The study identified the human resources competencies in South Africa which are attributed to employability and subsequently career success; the study also tested the applicability of the competency model proposed by the SABPP. Purpose: The study explored human resource competencies, employability and career success in South Africa. It targeted participants registered as master or chartered practitioners with the SABPP. As human resource management is professionalising, there is a need to align the requirements of the profession to what the stakeholders (employers, universities, graduates and professional bodies) require. Without a set baseline for competencies which are instrumental to human resource employability and career success, it becomes challenging to identify human resource shortcomings in the workplace. Method: The study made use of an interpretive orientation. This interpretivist approach was adopted for two reasons – it could provide useful insight to human resource employability and secondly, to gain insight into the experiences of participants. Purposive sampling was used to solicit participants as the researcher decided to select practitioners registered as master or chartered HR professionals with the SABPP. In the study, 35 practitioner interviews were conducted. Thematic analysis was used to analyse data and themes were derived from this. Main findings: The study identified: Volunteering; Work experience; Internships; Networking; Recommendations; Easy access to job market; Extracurricular activities; Resilience; Research; Having the right qualification; Recruitment agencies; Creativity; Further education; Willingness to learn; Attitude; Work ethic; Equity legislation; Work readiness; Passion for the job; Emotional intelligence; Personality; Positive psychology; Critical thinking; Emotional maturity; Behavioural competencies; Emotional intelligence; Technology; Entrepreneurial orientation; Technology and Entrepreneurial orientation as the factors which make one employable. Lack of work experience, Lack of jobs, Expectations of the world of work, Flooded market and No right qualification for HR professionals were identified as factors which make one unemployable. The competencies which are essential for HR employability and career success were identified. The meaning of career success for human resource practitioners was identified as: contribution to strategy. Being entrepreneurial, enjoying what one does, support from organisation, mastering HR competencies, income, v career planning and career were the themes identified to infer the meaning of career success. Areas of dissatisfaction were also identified from practitioners as: being underutilised; lack of a concise career path; always greener ‘on the other side’; monetary dissatisfaction; glass ceiling; and lack of contribution to strategy. After the SABPP model had been introduced, it enhanced organisation efficiency and guidance to HR strategy. It was used by practitioners to meet organisation objectives and to set objectives for personal development; however, in some organisations, the model was yet to be implemented and the public sector was putting in place a framework to be in line with the SABPP competency model. Some had no model in place and thus there was no impact on such organisations’. With regards to the competency model, its applicability to the human resource context and its shortcomings were deliberated upon. Practitioners gave their opinions of the applicability of the SABPP competency model: Model lays a solid foundation for HR as the Model justifies HR to the boardroom; Model covers all essential HR competencies. However, the model was also criticised as it was: too academic, lacked personal characteristics; nothing new here and it is relatively unknown by other practitioners. Practitioners also identified competencies they regarded as key: these were classified as traditional, modern and behavioural. Lastly, practitioners suggested competencies they think must be added into the SABPP competency model: the human touch; work ethic; love for people, passion for the profession, personality, emotional intelligence, attitude, behavioural competencies, positive psychology and arithmetic numeracy were identified as key items to be added. Human resource practitioners were content with the state of the model; the general weakness was the omission of personal attributes which are crucial for effective performance within the HR profession. Contribution: The study is a step towards enhancing sector-specific employability. In attaining employability, the generic skills, which are crucial, have to be cemented by disciplinespecific knowledge. Attaining a mark of 65% and above is a reflection of trainability of a job seeker. The meaning of career success is derived from the areas of dissatisfaction and satisfaction of practitioners. HR practitioners value contribution to strategy and are acknowledged for what they are doing. The legal framework in South Africa hinders career progression. There are 12 traits (networking, positive psychology, interpersonal strength, human touch, work ethic, love for people, passion for the profession, personality, emotional intelligence, arithmetic competency, attitude, behavioural competencies and being vi entrepreneurial) which are essential for effective performance which must be incorporated in the SABPP competency model. From the study, HR must go back to basics, master the basics and in doing so, create a solid foundation for HR ascendancy to the boardroom Managerial implication The implications of the study are synonymous to universities and the HR curriculum, the professional body and the future HR professional. HR graduate employability links labour market requirements to higher education. Higher education offers HR degrees for candidates who are willing to work in HR. The study is a contribution to the global professionalisation of human resource management. South Africa is setting the trend as the SABPP is actively involved in the certification of human resource curricula, setting standards and providing a sound code of ethics.

- Description: The 2015-2016 student movements in South African higher education sharply critique what was perceived to be the slow pace of institutional transformation and decolonisation in institutions of higher learning (see Badat, 2016; Heleta, 2016b; Mbembe, 2016). One of the academic fields that has come under scrutiny is Political Studies, which has been accused of being un-transformed, irrelevant and not reflecting local, indigenous scholarship in curricula or pedagogy (see for example Matthews, 2018; Mngomezulu & Hadebe, 2018; Tselapedi, 2016). Although this literature critiques neo-colonial predominance of western thought within the field, and the need to re-centre non-Western modes of being, thinking and intellectualising, I argue that this literature actually considers epistemologies without necessarily making a razor sharp critique at the underlying mechanisms and processes of Political Studies knowledge, and the extent to which it can be decolonised and transformed. It is on this gap that I make a contribution to the field.This study is positioned in the field of higher education decolonisation, with a specific focus on exploring knowledge and knower structures in Political Studies. I explore the various ways in which knowledge is valued and legitimated in the field of Political Studies by asking the “how” question – that is, how is knowledge legitimated in Political Studies? This includes a consideration of how the Postgraduate Diploma in International Studies (PDIS) programme, designed to promote and enable an “expert in African International Studies”, legitimates a certain kind of knower in the field. I employ Basil Bernstein’s pedagogic device as a theoretical foundation for exploring 1) what the field of Political Studies knowledge production looks like, 2) how knowledge is recontextualised from the field of production and into the PDIS curriculum, and 3), how that knowledge is legitimated and evaluated through the programnme’s assessment documents, and what they revel as valued and legitimate curriculum knowledge in the field. Karl Maton’s Legitimation Code theory (LCT), specifically Specialisation, is called upon to offer sharp analytical tools for investigating the underlying mechanisms and processes of the knower and knowledge structures that the programme legitimates. It particularly sheds some insight on the kinds of gazes that are valued in the field of Political Studies in general, and in the PDIS programme in particular. The case study for this research is Rhodes University, a historically white university which offered insight and contested history into the kinds of being, knowledges and knowers that were historically legitimated and valued in the institution, as well as the current institutional landscape, and challenges that the institution is grappling with. The data generation included the formally planned curriculum as contained in the programme’s curriculum documents. These included course outlines, seminar critiques, presentations, class participation; class discussions; essay questions and exams/exam portfolio. The data generation also included semi-structured interviews with the lecturers who were regarded as the “recontextualising agents”, who taught in the programme and who offered key insights on some of the curriculum choices regarding selection, pacing, sequencing and evaluation of the curriculum knowledge in the PDIS programme.This study revealed that that the PDIS programmes values and legitimates curriculum knowledge by ensuring that students have a critical understanding of African political economy, war and conflict on the African continent, as well as the challenges of peacekeeping and peace building in new and fragile African states. This was also seen in how the attributes and dispositions of knowers were also valued in how students needed to have social and cultural gazes in order to access the curriculum and to successfully participate as knowers in the field. This suggested that access to both curriculum knowledge and to being a valued knower in the field, could be said to be relatively open and unrestrictive. In this study, I first argue that looking critically at how Political Studies knowledge is recontextualised from the field of production and into the PDIS curriculum can be seen as a decolonising process as it enables us to see the underlying mechanisms and processes of how Political studies knowledge and knowers are valued and legitimated in the field. This offers us an insightful space to see to what extent the fields of production, recontextualisation, as well as reproduction of Political Studies in general, and the PDIS programme in particular, could be said to have a colonising gaze. It also offers insight on how we can go about exploring, transforming and decolonising Political Studies and the PDIS programme. Secondly, exploring the knowledge and knower structures of the PDIS programme can help curriculum designers, lecturers and students identify the knowledge and knower codes of the curriculum, and to critically reflect on their curriculum codes and how to enable epistemological access to students. Furthermore, this study can help lecturers and curriculum designers construct their curriculum in ways that are inclusive, open, and socially just, by being critically aware of the kind of knowledge that they choose to legitimate, and those they choose to disregard in their knowledge recontextualisation and its evaluation. , Unyaka wezi 2015-2016 wombhikisho wabafundi eningizimu afrika zemfundo ephakeme umcwaningi nokungabikhona kakhulu ukuthi kube kancane awuhambi zesikhungo kanye decolonisation ezikhungweni of higher learning (bheka badat, nowezi-2016; Heleta, 2016b; Mbembe, nowezi-2016). Enye yenkambu yezemfundo ephakeme ethe yaba ngaphansi kokuhlolisiswa kabanzi izifundo zezombusazwe, ebhekene nezingqinamba zokungashinsthi, ukungabi lusizo endaweni, ukungabi yisithombe somphakathi, nokukungangeneleli isifundo somdabu kwezemfundo noma i-pedagogy (bheka isibonelo Matthews, 2018; Mngomezulu & Hadebe, 2018; Tselapedi, nowezi-2016). Nakuba lo mbhalo ugxeka ineo-kholoni ikakhulukazi imicabango yasentshonalanga, nokudinga ukubuyekezwa indlela yokucabanga nobuhlakani okungasibo baseNtshonalanga. Ngiyaphikisana nokuthi lo mbhalo ubuyekeza i-epistomology ngempela ngaphandle kokucwaninga kabanzi ukusetsenziswa kobuhlakani nolwazi lwezemfundo yombusazwe, kanye nokwandisa izinguquko noshintsho. Ngizophonsa esivivaneni kulolu gebe olulapho. Lolu cwaningo lusesimeni sokwenza izinguquko kwinkundlazwelo yemfundo ephakeme, ikakhulu ukuhlola ulwazi kanye nezakhiwo ze-knower kwezemfundo yombusazwe. Ngibheka izindlela ezahlukene ngolwazi kanye nokuba semthethweni kwinkundlazwelo yezemfundo zombusazwe ngokubuza umbuzo “kanjani”-ngokuthi, ulwazi lubekwa kanjani ngokomthethwo wezemfundo yombusazwe? Lokhu kubandakanya inkokhelo yombuzo wokuthi kwenzakala kanjani ukuthi ipostgraduate Diploma in International Studies (pdis), yenzelwe ukukhuthaza kanye nokuba wumpetha kwi African International studies”, ukwenza semthethweni eminye yenkundlazwelo yama-knower. Ngisebenzisa ithiyori ya Basil Bernstein ukuhlola 1) Ibukeka kanjani inkundla yokuhkiqiza yezemfundo zezombusazwe, 2) ngolwazi lobuhlakani enkundleni lapho nasesikhathini uhlelo lwezemfundo PDIS yenza umkhiqizo kanye 3), futhi ukwazi ukuthi khona lusemthethweni uhlelo nokuhlola, nokuthi yini abayiveza ukuthi isemthethweni kwizifundo zolwazi. Ithiyori ka Karl matonâ legitimation code theory (lct), ikakhulu Specialisation, yiyona enganikeza kafuphi izinsiza zokuphenya indlela kanye nenqubo ye-knower kanye nolwazi lwesakhiwo esisemthethweni. Iveza kabanzi izindlela zokubheka ezisemqoka nezisematheni kwinkundla yezemfundo zombusazwe kanye nohlelo lwe PDIS ikakhulukazi Indawo lapho ngizoqhuba khona lolu cwaningo iNyuvesi yaseRhodes, ngokomlando iNyuvesi yabamhlophe enikezana ukuqonda nokuncintana komlando kokungena kwezinhlobo, ubuhlakani kanye nama-knower omlando osemthethweni kanye nokhethekile kulesi sikhungo, kanjalo ne-Landscape yesikhungo samanje, kanye nezinselelo lesi sikhungo sikahulumeni esibheke nazo. Idatha equkethwe ifaka izifundo ezihleliwe ngokomthetho njengokuba zitholakala ezifundweni ezihleliwe kumbhalo. Lokhu, kubandakanya isifundo esinye, amasemina abuyekeziwe, izethulo, nokubamba iqhaza ekilasini; izingxoxo zekilasi; imibuzo yendaba kanye nezivivinyo / nokuhlolwa kwezivivinyo. Idatha yesizukulwane iphinde ibandakanye izingxoxo ezihleliwe kanye nabafundisi abathathwa njengabantu abayizingcithabuchopho, abafundisiwe kulo mkhakha kanye naba neso ekukhethweni kwamanye amakharikhulamu abhekelele ukuhlunga, i-pacing, ukulandelela kanye nokuhlolwa kwekharikhulamu kulwazi lohlelo i-PDIS Lolu cwaningo ludalule ukuthi izinhlelo ze-PDIS zikubeka emqoka kanye nokubeka emthethweni ubuhlakani bekhurikhulamu ngokucophelela ukuthi abafundi bakuqonda ukubaluleka okulunzulu ngezomnotho wombusazwe wase Afrika, yimpi nokungqubuzana ezwenikazi lase-Afrika, ukugcina ukuthula kanye nezinkinga ekwakheni uxolo kanye nobuthakathaka / nophukayo kwezwekazi i-Afrika. Lokhu futhi kubonakele ngendlela yokubambisana kanye nokuziqhathulula kwama-knower aabalulekile ekufundiseni abafundi ngokudinga kokuba nezenhlalo kanye nesiko ukuze bakwazi ukuthola ikhurikhulamu kanye nokubamba iqhaza ngempumelelo njengama-knower kule nkundla. Lokhu kuchaze ukuthi ukufinyelela kuhlelo lokufunda kanye nokuba yilunga lama-knower, kungaba ukuba babonisane ngendlela evulelekile kanye nengenamkhawulo. Kulolu cwaningo, ngaqala ngabheka kabanzi ngokubalulekile ukuthi izifundo zezombusazwe ngolwazi lobuhlakani kwinkundlazwelo yokukhiqiza kanye nePDIS kungabonwa njengenguquko eyenza ukuba sikwazi ukubona ezinye izindlela zokusebenza kwezemfundo zombusazwe kanye nokubeka phambili ama-knower. Lokhu kusenza sibone ukubaluleka komkhiqizo wale nkundla, ukubuyekezwa kwezobuhlakani, kanye nomkhiqizo wezemfundo zombusazwe, kanye nohlelo lwe PDIS ikakhulukazi, kungathiwa ingaba nokubanjwa kokubheka. Iphinde isambulele kabanzi ukuthi singahlola, sense izinguquko kanye noshintsho kwezemfundo zombusazwe kanye nohlelo lwe PDIS. Okwesibili, ukuhlola ulwazi kanye nezakhiwo ze-knower ze-PDIS kungasiza abaklami bekhurikhulamu, abafundisi kanye nabafunsi ukukwazi ukuhlonza ulwazi nekhurikhulamu yekhodi ye-knower, kanye nokwazi ukubuyekeza kabanzi amakhodi ekhurikhulami yabo kanye nokwazi ukwenza i-epistemology ukuba abafundi bafinyelele kuyo. Ngaphezu kwalokhu, lolu cwaningo lungasiza abafundisi kanye nabaklamu bekhurikhulamu ukuba bakwazi ukwakha ikhurikhulamu yabo ngendlela ekhethekile, evulelekile, ngokwenhlalo nje, okubalulekile ukuthi uhlobo lophi lolwazi abakhetha lube semthethweni, kanye nalabo abakhetha ukungayilandeli inqubomgomo yolwazi kanye nokuhlola.

- Description: In today’s world, information is the foundation on which every strata in society is built and established. As we are in the jet age, the use of Information Communications Technology (ICT) is sine-qua-non to academic development. It is equally important to acquire skills and build capacity in ICT applications, as well as reflect on the demographic factors that determine the utilization of electronic resources among the undergraduate respondents. ICT has also evolutionalized professionalism in librarianship by providing delivery of appropriate, suitable and value-added information services in digital format. This research, therefore, investigated undergraduate students’ ICT literacy skills and demographic factors as determinants of electronic resources use, with selected tertiary institutions of learning in Eastern Cape South Africa as a case study. The study was premised on the Diffusion of Innovation Theory (DOI), Technology Acceptance Model (TAM) and the Theory of Reasoned Action (TRA) with the aim of appraising undergraduate students’ ICT literacy skills and demographic factors as causative elements of e-resources utilization in designated Eastern Cape universities in South Africa, as well as to unravel the impact of the theories on the adoption of technology and the perceived utilization of the electronic resources. The application of DOI, TAM and TRA theories for this study exemplifies the acceptance and usage of technological innovations by envisioned users in ICT literacy skill and electronic resources research, and these theories formed the theoretical basis to strengthen the study. The specific x objectives of the study are: To ascertain how undergraduate students in selected Higher Education Institutions (HEIs) in the Eastern Cape access e-resources; to determine the level of influence of ICT literacy skills on the use of electronic resources by Undergraduate students in the selected universities; to determine the regularity levels of use and problems encountered in the use of electronic resources by Undergraduate students in the selected universities; to ascertain the contributions of demographic factors on the use of electronic resources by Undergraduate students in the selected universities; and to determine the attitudes and perceptions of undergraduate students towards the use of eresources. The approach of the study was in threefold; one, general discussion regarding ICT literacy skills of the respondents and secondly the demographic factors that determine electronic resources use of undergraduate students in the University of Fort Hare and Rhodes University. Finally, ICT literacy skills and demographic factors were investigated with the applicability of TAM, DOI and TRA theories Specifically, under these theories (TAM, TRA and DOI), TAM and TRA models were used to explain behavioural intention and to envisage user acceptance of technology usage (electronic resources), and to elucidate the correlation between the respondent’s (undergraduate students) perceptions, attitudes, beliefs and ultimately system utilization. DOI was conceptualized in this study as a valued tool for appraising the effect of demographic factors on the utilization of electronic resources among the undergraduate students in their academic pursuit. The major findings of the study specifies that ICT literacy skills and demographic factors determine the use of electronic resources. Hence, it is reasoned in the thesis that ICT xi literacy and demographic factors affects the frequency of electronic resources with those, for instance, who have obtained high ICT literacy skill levels when compared to others who are yet to develop their ICT literacy skills. Further, it has been disclosed elsewhere in the study that in terms of age, the younger undergraduate students (from 21 to 30 years) utilize electronic resources more regularly than their older colleagues (those who are 30 years of age and above).The study was approached with the adoption of the mixed-method research technique. The administration of a total of 377 copies of the questionnaire to undergraduate respondents in the aforementioned HEIs, (out of which 266 copies were returned), was conducted with in-depth interview conversations comprising of ten participants, with six respondents selected in the University of Fort Hare and four respondents from Rhodes University. Data acquired from the study were processed and analyzed with the aid of Statistical Package for Social Science (SPSS) for the quantitative data. In the light of the theoretical frameworks of the study, research results established that the ICT experience of the undergraduate respondents greatly influences their proficiency levels. This hypothesized assertion was subjected to statistical validity test through regression analysis. The result depicts that the p-value is 0.49 (which means that p≤ 0.05), and interprets to mean that the hypothesis is accepted. Also, the findings of this study depicts that the utilization of electronic resources by the respondents is mostly for entertainment purposes (such as viewing online videos, listening to sport commentaries, music and video downloads, e-mail communications, chatting with other people) had the highest rankings from the component matrix analysis which were greater than 0.5. From the forgoing, this is interpreted to mean that the respondents possess excellent proficiency in ICT literacy skills as well as in the use of Microsoft packages. xii Also, in the course of the in-depth research interview, it was discovered that most of the interviewees have excellent proficiency in ICT literacy skills. Generally, gender is an essential element that determines accessibility and e-resource utilization of respondents to electronic resources through the home and from other sources. Furthermore, it was discovered that that language is not a determinant regarding respondents’ accessibility and e-resource utilization from other sources of access to respondents. The analysis of this study revealed that more males, who are within the active e-resource using age bracket of 21 to 30 years old access and utilize electronic resources through the residences than their female counterparts. This age bracket is followed in terms of access and use of e-resources through residences by the respondents that are 20 years and below. A chi-square test of independence was also performed to survey the level of correlation between age and access to E-resources. A small p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p-value (> 0.05) shows weak evidence against the null hypothesis, so you reject the null hypothesis i.e. X2 (3, N=53) = 7.82. The Pearson chi-square (p-value) generated was .294, which is construed to mean that it is insignificant. Therefore, the explanation is that age has no influence on access of respondents to electronic resources through cybercafé. In order to make ICT literacy skills more beneficial to the undergraduate students in the selected HEIs, recommendations were made in this study. Firstly, there is a need for mass enlightenment campaigns on the use and benefits of E-resources among undergraduate respondents, the building of capacity of the undergraduate students in the use of electronic resources ICT literacy skill development programmes, need for intervention programmes focusing on the application xiii of some E-resources and software where the students are ranked low. Further, it is recommended that female students need to be encouraged to use E-resources. Also, delivery and empowering of Wi-Fi services, as well as the provision of CD- ROM databases should be considered.

The study was premised on the Diffusion of Innovation Theory (DOI), Technology Acceptance Model (TAM) and the Theory of Reasoned Action (TRA) with the aim of appraising undergraduate students’ ICT literacy skills and demographic factors as causative elements of e-resources utilization in designated Eastern Cape universities in South Africa, as well as to unravel the impact of the theories on the adoption of technology and the perceived utilization of the electronic resources. The application of DOI, TAM and TRA theories for this study exemplifies the acceptance and usage of technological innovations by envisioned users in ICT literacy skill and electronic resources research, and these theories formed the theoretical basis to strengthen the study. The specific x objectives of the study are: To ascertain how undergraduate students in selected Higher Education Institutions (HEIs) in the Eastern Cape access e-resources; to determine the level of influence of ICT literacy skills on the use of electronic resources by Undergraduate students in the selected universities; to determine the regularity levels of use and problems encountered in the use of electronic resources by Undergraduate students in the selected universities; to ascertain the contributions of demographic factors on the use of electronic resources by Undergraduate students in the selected universities; and to determine the attitudes and perceptions of undergraduate students towards the use of eresources. The approach of the study was in threefold; one, general discussion regarding ICT literacy skills of the respondents and secondly the demographic factors that determine electronic resources use of undergraduate students in the University of Fort Hare and Rhodes University. Finally, ICT literacy skills and demographic factors were investigated with the applicability of TAM, DOI and TRA theories Specifically, under these theories (TAM, TRA and DOI), TAM and TRA models were used to explain behavioural intention and to envisage user acceptance of technology usage (electronic resources), and to elucidate the correlation between the respondent’s (undergraduate students) perceptions, attitudes, beliefs and ultimately system utilization. DOI was conceptualized in this study as a valued tool for appraising the effect of demographic factors on the utilization of electronic resources among the undergraduate students in their academic pursuit. The major findings of the study specifies that ICT literacy skills and demographic factors determine the use of electronic resources. Hence, it is reasoned in the thesis that ICT xi literacy and demographic factors affects the frequency of electronic resources with those, for instance, who have obtained high ICT literacy skill levels when compared to others who are yet to develop their ICT literacy skills. Further, it has been disclosed elsewhere in the study that in terms of age, the younger undergraduate students (from 21 to 30 years) utilize electronic resources more regularly than their older colleagues (those who are 30 years of age and above).The study was approached with the adoption of the mixed-method research technique. The administration of a total of 377 copies of the questionnaire to undergraduate respondents in the aforementioned HEIs, (out of which 266 copies were returned), was conducted with in-depth interview conversations comprising of ten participants, with six respondents selected in the University of Fort Hare and four respondents from Rhodes University. Data acquired from the study were processed and analyzed with the aid of Statistical Package for Social Science (SPSS) for the quantitative data. In the light of the theoretical frameworks of the study, research results established that the ICT experience of the undergraduate respondents greatly influences their proficiency levels. This hypothesized assertion was subjected to statistical validity test through regression analysis. The result depicts that the p-value is 0.49 (which means that p≤ 0.05), and interprets to mean that the hypothesis is accepted. Also, the findings of this study depicts that the utilization of electronic resources by the respondents is mostly for entertainment purposes (such as viewing online videos, listening to sport commentaries, music and video downloads, e-mail communications, chatting with other people) had the highest rankings from the component matrix analysis which were greater than 0.5. From the forgoing, this is interpreted to mean that the respondents possess excellent proficiency in ICT literacy skills as well as in the use of Microsoft packages. xii Also, in the course of the in-depth research interview, it was discovered that most of the interviewees have excellent proficiency in ICT literacy skills. Generally, gender is an essential element that determines accessibility and e-resource utilization of respondents to electronic resources through the home and from other sources. Furthermore, it was discovered that that language is not a determinant regarding respondents’ accessibility and e-resource utilization from other sources of access to respondents. The analysis of this study revealed that more males, who are within the active e-resource using age bracket of 21 to 30 years old access and utilize electronic resources through the residences than their female counterparts. This age bracket is followed in terms of access and use of e-resources through residences by the respondents that are 20 years and below. A chi-square test of independence was also performed to survey the level of correlation between age and access to E-resources. A small p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p-value (> 0.05) shows weak evidence against the null hypothesis, so you reject the null hypothesis i.e. X2 (3, N=53) = 7.82. The Pearson chi-square (p-value) generated was .294, which is construed to mean that it is insignificant. Therefore, the explanation is that age has no influence on access of respondents to electronic resources through cybercafé. In order to make ICT literacy skills more beneficial to the undergraduate students in the selected HEIs, recommendations were made in this study. Firstly, there is a need for mass enlightenment campaigns on the use and benefits of E-resources among undergraduate respondents, the building of capacity of the undergraduate students in the use of electronic resources ICT literacy skill development programmes, need for intervention programmes focusing on the application xiii of some E-resources and software where the students are ranked low. Further, it is recommended that female students need to be encouraged to use E-resources. Also, delivery and empowering of Wi-Fi services, as well as the provision of CD- ROM databases should be considered.

- Description: Drought is a huge limiting factor in maize production, mainly in the rain-fed agriculture of subSaharan Africa. In response to this threat, drought-tolerant (DT) maize varieties have been developed with an aim to ensure maize productivity under drought conditions. This study assessed the impact of smallholder farmers’ adoption of DT maize varieties on maize productivity. The first step into understanding the impact of adoption of these varieties on smallholder farmers’ productivity was to first identify the varieties that they were growing. To achieve this, data was collected through the means of a household survey of 600 farmers from Karonga, Chikwawa and Salima districts in Malawi. The major findings drawn were that though most of the farmers have adopted the use of hybrids, as they are fairly common among the varieties that are being grown, most of these hybrids were not drought tolerant varieties. Previous studies had concluded that most of the farmers in Malawi were still growing local varieties. Results from this study showed a major increase in the use of hybrids with SC403 being the most grown variety. The second step in the analysis of the impact of DT maize adoption was to analyse the level and intensity of adoption of these varieties among the smallholder farmers. This was done using a Double Hurdle Model. The results from the double hurdle showed that only 23% of the sampled farmers were growing one or more DT varieties on their plots. Generally, farmers’ decision to use improved agricultural technologies and the intensity of the use in a given period of time are hypothesized to be influenced by a combined effect of various factors such as household characteristics, socioeconomic and physical environments in which farmers operate. The results in this study have shown that the geographical location of farmers plays a significant role in the decision to adopt as well as off-farm income and input subsidies. In terms of intensity, the results revealed that the farmers allocated an average of 0.46 ha of their land under maize cultivation to DT varieties. The results also showed that the intensity of adoption was influenced by gender, household size, whether or not the farmer is recycling the seed and soil fertility. The next step in the study was analysing the impact that intra-seasonal weather variability had on maize productivity. This was done by using daily weather variables for the whole growing season so as to take into account evaporation, rain gaps and other intra seasonal weather limitations. The Just and Pope Production Function was used to analyse the impact of intra-seasonal weather vi variability on productivity. The results suggest that the amount and distribution of rainfall have a strong impact on the development of the maize crop and consequently the quantity harvested. From the results, there was evidence of high variability in rainfall characteristics in terms of the intraseasonal distribution which in turn translated into high variability in maize quantity harvested by the smallholder farmers in Malawi. Lastly, the Endogenous Switching Regression Model was used to analyse the impact of adoption of DT varieties on yield. The results showed that the adoption of DT varieties increases productivity. The use of counterfactual data from the Endogenous Switching Regression (ESR) allowed for an in-depth analysis of the productive implications. The results from the ESR model showed that the farm households that did not adopt, had they adopted, they would have increased their productivity. Furthermore, the results indicated that the use of DT maize varieties successfully delivered relatively less reliance on the total and net rainfall, that is, adopters managed to support their productivity in the face of changing climate while the non-adopters were adversely affected by an increase in temperature and decrease in total rainfall. Adoption of DT varieties increased output among smallholder farmers by 441.33 kg which translates to a 41% increase. Conclusively, the results from this study showed that smallholder farmers are adopting new and improved hybrids and improved OPVs and moving away from the use of local varieties. However the new varieties they are currently using are mostly not DT varieties. This is an interesting finding because the farmers when asked about their preferred traits in maize seed mentioned drought tolerance, therefore the low level of adoption points to numerous factors. These factors include lack of awareness of these varieties among smallholder farmers and unavailability of seed. The results also showed that the level of adoption was low among the farmers. With respect to productivity, this study has shown that adoption of DT varieties by smallholder farmers will increase their yield in the face of climate change

- Description: This study deals with the implementation of Multicultural Education by High School Teachers (HST) in multicultural classrooms in selected high schools in Chris Hani West District of Education, Eastern Cape Province, South Africa. The purpose of the study was to explore the implementation of ME by HST in multicultural classrooms. The study was located in an interpretivist paradigm, which enabled the researcher to obtain data directly from the subjects themselves, by sitting with the participants and hearing their views, voices, perceptions, opinions, interpretations and expectations with regard to the implementation of Multicultural Education (ME) in High Schools. Case study research design was adopted in the study in order to get in-depth information about what is happening in schools. Purposive sampling strategy was used by the researcher to select individuals who could offer an authentic account of the phenomenon under study. The researcher collected data, which were qualitative in nature utilising basic semi- structured face- to- face interviews, focus groups, classroom observations and document analysis. The data were collected and analysed inductively for the themes and patterns to be derived. The study revealed that ME approach is being implemented by some of the teachers in the selected schools however, there were challenges encountered. According to the findings of the study, it was revealed that teachers did not receive training from the Department of Education on how to implement ME approach at the schools. It was also found that teachers were empowered only with different types of prescribed textbooks and the guidelines on the course content in their learning.The study recommends that ME should be part of the curriculum for in-service teacher training. The school policy framework should enforce and regulate the practice of ME by the HST. In this regard, teachers need to be well equipped to be able to implement ME effectively. Therefore, the classroom strategies and interventions need to be created to provide equal learning opportunities for all diverse learners from different backgrounds with different learning needs in the multicultural classrooms. However, the Department of Education should organise workshops and seminars for the teachers to be able to implement ME effectively in the classrooms. v Furthermore, the Department should ensure that the content of the books that the publishers select for the learners do incorporate ME throughout the topics and themes of the books. Adequate resources should be provided for both learners and teachers for the successful implementation of ME. Parents should be involved for new developments and curriculum transformation in the school level as vital stakeholders. This should encourage the ownership of the education process by everybody involved to yield positive outcome. Language policy on the curriculum should be revisited for all the learning areas except the learners’ mother tongue. This could make the learners understand the content of their relevant learning areas easily. Therefore, teachers need to shift from old approach to the new approach to meet and be able to address the needs of the learners effectively. Support and monitoring should be rendered by the Department of Education for the successful implementation of ME.

- Description: The purpose of any education system is to deliver a quality educational product. Various forms of assessment are used to ensure the suitability of the product and inform decisions. In South Africa, School-Based Assessment(SBA) is one of the tools used to assess the content competences, skills, values and attitudes; to provide learners, parents and teachers with results that are a meaningful indication of what the learners know, understand and can do at the time of assessment (DBE, 2012). Surprisingly, on a yearly basis, Umalusi reports reveal that SBA marks are rejected resulting in the learners being resulted on mostly the year end examination. The purpose of this study was to examine the implementation of SBA with a view to unearth the factors contributing to the perennial rejection of SBA marks, resulting in learners from some schools being unfairly assessed. To explore the research problem, a mixed methods study, employing a concurrent triangulation design, was employed. Total Quality Management theory was the theoretical framework anchoring this study. Sub research questions to interrogate the research problem focused on examining the roles of the teachers, learners and parents in the implementation of SBA; assessing the structures in place to support the implementation of SBA; examining how teachers, learners and parents play complementary roles in the implementation of SBA; and identifying strategies to enhance the implementation of SBA in South African (SA) high schools. Data were collected using Questionnaires, interviews and focus group discussions with purposively selected samples of teachers, learners and SGB chairpersons from high schools in White River Circuit in Mpumalanga Province in South Africa. The use of mixed methods produced quantitative and qualitative data which were independently analysed and merged during interpretation. Findings revealed that: participants and respondents confirmed the various roles of SBA in teaching and learning; structures were in place to support the implementation of SBA in high schools; complementarity of roles were sporadic in the implementation of SBA in high schools; and various strategies were employed to enhance the implementation of SBA in high schools. Implications for teaching and learning focused on realigning the implementation processes in the production of a quality educational product, and maximising its benefits to teachers, learners and parents.

- Description: Prior to 1994, religious freedoms were largely restricted because the constitution at the time vested its powers in the president who was at the time was Dr. Hastings Kamuzu Banda. Banda, who ruled Malawi for thirty years, sought to present Malawi to the outside world as a Christian nation. This was purposefully done by ignoring the existence of other religious faiths in the country of which Rastafari was one. Although the Rastafari movement was in existence during Banda’s presidency, most Rastas found it difficult to practice their religious beliefs freely. Because of this, it was found that throughout the three decades Banda was in power, the Rastafari movement in Malawi was virtually underground. This further gave the public impression to the public at the time that Rastas were non-existent in the country. It was only after the general elections of 1994 that Malawians became aware of the existence of the Rastafari movement in the country. With that said, there remains a paucity of written information on the Rastafari movement in Malawi, that is before and after the 1994 general election. To be able to establish why the Rastafari movement continues to grow in Malawi, this thesis began by addressing the question of why a certain group of individuals would seek becoming to Rastas in Malawi including its impact on their lives including relationships with both friends and family members. For the many that embraced Rastafari, the intention was to embrace a spiritual identity that was separate to that of their parents. Most raised the concern that the religions that they were previously affiliated did not allow them the freedom to explore their spirituality. This further raises the question regarding the link between established religions and spirituality. In as much as Rastafari has provided the individuals in this study a sense of meaning and identity in their lives, they have had to contend with facing confrontation with friends and family members. This thesis also explored the experiences that come with being a Rasta in Malawi. Amongst the issues that are of concern to the Rasta community is that for the many Rasta children that attend public schools, most are denied their right to attend classes with dreadlocks. Most Rastas had hoped that with the advent of democracy in Malawi, their fundamental rights would be recognised and protected under the constitution. What this thesis has demonstrated that despite the existence of democracy in Malawi, it did ultimately result in a society that would be open to diversity. What this study has demonstrated is that Malawi continues to remain a highly conservative society. This is further illustrated in the way Malawian Rastas have had to contend with being denied employment opportunities including their fundamental right to smoke chamba (marijuana) freely. This thesis set out to argue that the democracy brought about by the elections of 1994 did not necessarily result in the improved conditions of minority religious groups like Rastafarians. This is despite the current constitution allowing for religious freedom. Despite this, the thesis further set out to show that the Rastafari movement does have vital role in the current dispensation. The issues that make the Rastafari movement pertinent in present-day Malawi include issues of corruption and neo-colonialism. This thesis concluded that more must be done to improve the conditions of Rastas in Malawi. Some of recommendations that were raised in this study included reviewing the current policy regarding the length of hair that one wears to school as it relates to one’s religious beliefs. The other recommendation that was raised in this study includes amending the Religious and Moral Education (RME) school curriculum in order that it becomes inclusive of other religious faiths that are existing in the country. In addition, the current legislation regarding the possession of chamba must be amended to accommodate for religious groups such as Rastas who use it for religious purposes.

- Description: This case study was conducted in a small rural community called Mpembeni, in South Africa’s KwaZulu-Natal province. It was motivated by my observation of high levels of competence in ‘cattle knowledge’ amongst children coupled with a simultaneous failure at school. I view schools as integral parts of the community and consider them as being influenced by the community, which they in turn influence. This study set out to understand that which embodied informal learning in home/pasture-based contexts as well as formalised learning processes in schools. I used Sociocultural theory as the most congruent of educational theories to surface and illuminate the intergenerational learning processes that were taking place in the area. This warranted my use of research investigation methods that could, in non-intrusive ways, expose the everyday community practices that related to cattle as a particular medium of cultural expression. Ethnography, sourced from anthropology, aided by ethnomethods, was not only compatible with my study and the way in which I wanted to write out the research report, but also with my educational theory and its counterhegemonic intents. To understand the colonialities that framed the discord that embodied home and school as learning contexts, I used postcolonial theory, not only as a lens but as a counterhegemonic response. This theory also informed my research methodology as well as afforded me the reflexivity tools for an examination of my own intergenerational learning and the relational identities of myself as ‘Other’ in the lives of the research participants. It further facilitated the exploration of the potential for potential hybrid third spaces within the bubbling meeting nodes of the socio-cultural context of school and home/pasture based settings of learning. I observed cattle herding related practices, interviewed children, their parents and/or carers, dipping tank managers, livestock inspectors, community elders and members. I also analysed some of the written and unwritten content that made up the formal and informal based learning processes and reviewed some of the most recent South African Curriculum Statements and related texts on the representations of cattle. I sought views from teachers on their interactions with the people of Mpembeni, whose children they taught. I also explored axes of tension, silences and presences on anything related to cattle in schools. I argue and make a case for the development of thought by African scholars to advance Africa’s education rather than aid mimicry and the importation of theories of little congruence and relevance to the African context and Africa’s future. The study has made some contributions to new knowledge. This is in its exploration of sociocultural intergenerational methods and techniques that are employed for learning in community contexts, highlighting the importance of surfacing and understanding of children’s knowledge and experiences. The study has gone further to deliberate the in-betweenness of school and home learning environments, highlighting and unsilencing silenced, peripherised, new, old, considered irrelevant in the past, context and time congruent and liberatory knowledges. I propose that the knowledges located in these cleavages of difference be utilised to transform and create learning bridges between home and school environments. I propose that those ways of knowing that see others as nothings, be exposed and unlearned. Methods of learning that naturally unfold at home could be replicated at school with a recognition of the intergenerational methods, techniques, practices and the learning values in a critically constructive manner that narrows difference and othering.

- Description: Despite technological advances in water treatment and improved sanitation in many developing countries, acute microbial diseases still thrive and continue to distress millions of people. This is due to the high number of rural dwellers that still source water for drinking and other domestic uses from contaminated rivers. In South Africa, there have been reports on waterborne disease outbreaks, and specifically in the area understudy, two records of diarrhoeal outbreaks associated with consumption of river water were reported within the last decade. All those outbreaks and previous reports on isolation of other pathogenic bacteria within the area necessitated the conduction of this study in order to identify the potential causes of the cholera-associate diarrheal outbreaks previously reported in the area and nationally. This study was designed to assess the incidence of cholera-causing and non-cholera causing pathogens in final effluents and surface waters of the Raymond Mhlaba Local Municipality, Eastern Cape Province, South Africa. RiverK which serves as a major resource for domestic activities, agricultural practices as well as an abstraction point for a potable water treatment plant was used for this study. River-K freshwater and final effluents of its two feeder wastewater treatment plants were sampled monthly, over a twelve-month period (December 2016–November 2017). For purposes of confidentiality, the names of the wastewater treatment plants and river involved are coded in this report. A total of 108 water samples were assessed for the physicochemical parameters that influence the presence of Vibrio pathogens. For bacteriology, the membrane filtration method followed by polymerase chain reaction (PCR) was adopted to assess the incidence of cholera-causing and non-choleracausing Vibrio pathogens, as well as their virulence-associated genes from the two wastewater treatment plants and their receiving waterbody (River-K). Antibiotic susceptibility profiles of identified Vibrio species were determined using the disc diffusion method against a panel of xvi sixteen antibiotics commonly used as antimicrobial drugs of Vibrio infections. Multiple antibiotics resistance index (MARI) and phenotypes (MARP) were measured, and the existence of antibiotic resistance genes was evaluated by PCR using specific primer sets. Most of the physicochemical parameters measured (pH, TDS, temperature, salinity and DO) complied with the recommended standards for drinking water, while some fell short of the recommended limits (EC, turbidity, TSS, free chlorine). From the presumptive Vibrio isolates, 64.3% (476/740) were confirmed by PCR, with their Vibrio densities across all sampling points ranging between 0 and 2.7 × 104 CFU/100 mL, with high counts recorded in summer, hence their positive significant correlation (P< 0.01) with temperature. From the confirmed Vibrio isolates, only V. cholerae (53/476), V. mimicus (21/476) and V. parahaemolyticus (5/476) were detected. For virulence-associated genes, virulence genes homologous to V. cholerae virulence determinants, namely ompU (35%), TCP (14%), ACE (11%), ctx (7%) and HylA (4.5%) were widespread (independently) amongst the V. cholerae and V. mimicus species, while V. parahemolyticus isolates (100%) produced only the ToxR gene. Antibiogram profiling found resistance against some antibiotics such as Nalidixic acid (65%), Polymyxin B (43.8%) etc. The MAR indices ranged between 0 and 0.67 with 41.3% of the isolates recording MAR index values above 0.2. The results presented high degrees of MARPs ranging from four to eleven antimicrobials. For resistance gene detection, the SXT element was detected in 66% of the isolates, while cat1 (93%) was the most predominant, followed by aac (68%), ant (61%), with bla-V (7.1%) as the least detected gene. Findings from this study suggest that the wastewater effluents from the two wastewater treatment plants are potential sources of pathogenic Vibrio species and River-K contains a high quantity of pathogenic Vibrio species with fluctuating seasonal variations that reaffirm temperature as a strong reason for their abundance. The antibiotic-resistant Vibrio species isolated here carry a pool of virulence-associated genes and xvii antibiotic resistance genes, presenting a health threat to the communities that use it directly for domestic and irrigation purposes. In conclusion, some surface waters in the Eastern Cape Province, South Africa are widely contaminated with cholera-causing and non-cholera causing Vibrio pathogens; furthermore, some wastewater treatment plants are ineffective in adequately removing microbial contaminants and have become sources of pathogenic bacteria to their receiving waterbodie

- Description: The study endeavoured to find out how indigenous cereal crops in the form of sorghum, pearl millet and finger millet, popularly known as small grain, would help in increasing cereal production in the dry regions of Zimbabwe so as to alleviate food insecurity. For the past decade the nation’s cereal production has been on the decline with the country having to rely on grain imports from neighbouring countries to prevent hunger. Studies that have been carried out have indicated that these indigenous cereal crops are better suited for semi-arid regions like Matabeleland, used as a case study, where maize has almost always been a failing crop. The study examined representations of smallholder farmers through interviews held with agricultural personnel in Matabeleland North and Matabeleland South Provinces. The study argues that instead of relying on maize only as a staple crop, in the semiarid regions of the country, indigenous cereal crops are suitable alternative staple crops in Zimbabwe. Indications from the findings of the study are that diversification of staple crop production should stress the importance of state mediation, distribution and promotion of indigenous cereal crops. The researcher thus proposes that the reliance on indigenous crops be anchored in community food security, food sovereignty and rural food system perspectives, not negating the negative effects of climate change on food production. The results showed that despite progress made by the state in assisting farmers with agricultural inputs, very little has been achieved in alleviating food insecurity in the dry regions, as indigenous cereal crops continue being pushed to the periphery of the agricultural sector. iii The study concludes by putting forward that addressing the stated challenges could lead to the potential of indigenous cerealcrops potentially increasing the cereal supply for the nation, thus alleviating food security woes as these crops grow favourably even in the most adverse weather conditions and poor topography.

- Description: This manuscript details a study on laser surface treatment, a surface modification technique that is an easily flexible way of improving material surface properties of complex geometries. The research explored the potential of laser surface modification/treatment as a post welding surface processing technique for RFW Ti-6Al-4V ELI components by evaluating the microstructural effects, influence on fatigue life and the depth and magnitude of residual stresses induced. The outcome of this study reveals how post processing by laser surface modification affects crack initiation hence fatigue life and further explains mechanisms potentially contributing to enhanced joint properties. This study was accomplished by investigating the effect of laser surface treatment on surface properties of hourglass cylindrical rotary friction welded Ti-6Al-4V ELI specimens. Preliminary work was done in two stages. The first stage involved conducting laser surface treatment on 3 mm Ti-6Al-4V sheets. In this stage, an understanding of the process variables concerning the laser surface treatment process characteristics was established. Laser power and focus position were varied whilst scanning speed was kept constant. The observed macrographs were quantified in terms of laser penetration depth and width. A hardness and microstructural analysis was also conducted on selected specimens of the laser surface treated flat sheets trials. The second stage involved surface treatment of the hourglass fatigue specimen. This preliminary work allowed for the type and influence of treatment strategy to be analysed. The influence of treatment strategy on the depth of penetration was established with an emphasis on achieving homogeneity of the laser surface treated zone’s depth of penetration around the complete cylindrical specimen’s diameter. The final matrix involved varying laser power, scanning speed and focus position and the specimens were characterised by comparing hardness, residual stresses and microstructure. The results showed that laser surface treatment changed the hardness profile of the near surface of the specimen owing to the introduction of a homogenous microstructure at the surface as compared to a friction welded specimen. The microstructure was resolved using electron backscatter diffraction. A fully α-lamella microstructure was observed in the two specimens analysed at a position of 200 μm from the surface. The α-lamella had different width sizes with the low-power density specimen having a very fine microstructure as compared to that of the high-power density specimen. EBSD phase maps were also analysed for the parent, rotary friction welded only and friction welded laser surface treated specimens. The laser treated specimens showed virtually no β phase present as compared to the parent and rotary friction welded only specimens. LST processing improved the fatigue properties of the RFW specimens. The position of failure shifted from the HAZ to outside the RFW joint. This change in position was attributed to the surface modification by LST thereby introducing a more homogenous microstructure at the surface of the specimen. Additionally, it was also observed that the power density had an important role to play in the fatigue properties of the laser surface treated specimens. The high-power density LST specimens had a low fatigue limit compared to the low-power density specimens. The low fatigue limit at high- power density correlated with the residual stress results where the high-power density specimen had the highest attained surface tensile axial residual stresses. In conclusion, the main influences of laser surface treatment of small friction welded Ti-6Al-4V ELI components relate to an increase in fatigue properties by shifting crack initiation sites to less stressed areas. In this way, laser surface treatment could assist in the optimisation of manufacturing methodologies for small near net shape complex geometry components. The uniform and homogenous microstructure eliminates or reduces microstructural variations as observed in as welded components, reducing weld zone hardness variation. Additionally, the study showed that the introduction of a near surface refined microstructure inhibited crack initiation in the welded region.

- Description: There is growing recognition of the important role Construction Micro, Small and Medium Enterprises (CMSMEs) play in economic development. In 2013, Nigeria had about 36,994,578 Micro, Small, and Medium Enterprises (MSMEs) and 731,303 CMSMEs, about 1.99% of the total number of MSMEs in the country. However, 50% of CMSMEs in Nigeria close down within their first five years of existence. Consequently, only about 10% of CMSMEs in Nigeria survive, thrive, and grow to maturity. Enterprises failing within so short a time, portend a huge problem surrounding CMSME innovation and success. While literature seems to indicate innovation as the likely way out of CMSMEs failure, few researchers have considered the connection between CMSMEs innovation and their success. Hence, this research aimed to explore the effect of innovation(s) and innovation systems on the success of the Northern Nigerian CMSMEs. The research objectives were: to identify the types of innovation that are predominant in/peculiar to the Northern Nigerian CMSMEs; to determine how the types of innovation impact the success of the Northern Nigerian CMSMEs; to establish what the innovation systems that manage the innovation of the Northern Nigerian CMSMEs are; and, to determine how the innovation systems, promote innovation among the Northern Nigerian CMSMEs. Qualitative research method was utilised; consisting of 17 recorded interviews within Northern Nigerian which is the study area. The interview also employed structured interview guide, comprising structured open-ended questions to ensure consistency and rigour in the data collection process. The research adopted two stage non-probabilistic sampling, comprising judgmental and snowballing sampling for stage one and two respectively. In stage one, participants were drawn judgmentally based on their innovation and in stage two, the sample size was expanded, using a snowballing sampling technique where the participants in stage one suggested other participants who had also been innovative. Data collected were transcribed and open coded, while the codes for innovation types, and innovation impact on CMSME success were developed with the aid of a deductive code earlier developed from literature. The code occurrences were determined and categorised, and themes were developed. These themes were then subjected to interpretation and analysis. The research findings indicate that the predominant type of innovations within the CMSMEs in the northern part of Nigeria are product innovation, management innovation and service innovation. In addition, there are, technological application innovations, logistics innovations and labour innovations. These innovations impact on the profit, capital, customers, workers and the products of the CMSMEs studied. The innovations are responsible for the CMSMEs success periods, reasons for success and their salient points of success. Therefore, the research concludes that innovation impacts on the studied CMSMEs success. Consequently, the research achieved its aim. The study also discovered an absence of systems that support the innovation of CMSMEs in the northern part of Nigeria. Through this research, an innovation system framework has been developed and it is recommended that it be implemented because of the observed lack of innovation systems in Nigeria.

In addition, there are, technological application innovations, logistics innovations and labour innovations. These innovations impact on the profit, capital, customers, workers and the products of the CMSMEs studied. The innovations are responsible for the CMSMEs success periods, reasons for success and their salient points of success. Therefore, the research concludes that innovation impacts on the studied CMSMEs success. Consequently, the research achieved its aim. The study also discovered an absence of systems that support the innovation of CMSMEs in the northern part of Nigeria. Through this research, an innovation system framework has been developed and it is recommended that it be implemented because of the observed lack of innovation systems in Nigeria.

- Description: There is growing recognition of the important role Construction Micro, Small and Medium Enterprises (CMSMEs) play in economic development. In 2013, Nigeria had about 36,994,578 Micro, Small, and Medium Enterprises (MSMEs) and 731,303 CMSMEs, about 1.99% of the total number of MSMEs in the country. However, 50% of CMSMEs in Nigeria close down within their first five years of existence. Consequently, only about 10% of CMSMEs in Nigeria survive, thrive, and grow to maturity. Enterprises failing within so short a time, portend a huge problem surrounding CMSME innovation and success. While literature seems to indicate innovation as the likely way out of CMSMEs failure, few researchers have considered the connection between CMSMEs innovation and their success. Hence, this research aimed to explore the effect of innovation(s) and innovation systems on the success of the Northern Nigerian CMSMEs. The research objectives were: to identify the types of innovation that are predominant in/peculiar to the Northern Nigerian CMSMEs; to determine how the types of innovation impact the success of the Northern Nigerian CMSMEs; to establish what the innovation systems that manage the innovation of the Northern Nigerian CMSMEs are; and, to determine how the innovation systems, promote innovation among the Northern Nigerian CMSMEs. Qualitative research method was utilised; consisting of 17 recorded interviews within Northern Nigerian which is the study area. The interview also employed structured interview guide, comprising structured open-ended questions to ensure consistency and rigour in the data collection process. The research adopted two stage non-probabilistic sampling, comprising judgmental and snowballing sampling for stage one and two respectively. In stage one, participants were drawn judgmentally based on their innovation and in stage two, the sample size was expanded, using a snowballing sampling technique where the participants in stage one suggested other participants who had also been innovative. Data collected were transcribed and open coded, while the codes for innovation types, and innovation impact on CMSME success were developed with the aid of a deductive code earlier developed from literature. The code occurrences were determined and categorised, and themes were developed. These themes were then subjected to interpretation and analysis. The research findings indicate that the predominant type of innovations within the CMSMEs in the northern part of Nigeria are product innovation, management innovation and service innovation. In addition, there are, technological application innovations, logistics innovations and labour innovations.

- Description: Public institutions across the globe are usually faced with challenges of adopting creative ways for service delivery improvement in the form of innovative management. The development of innovative management in public institutions would be seen as a contribution in addressing the underlying challenges regarding service delivery, specifically in the developing countries such as South Africa. It is, however, observed that public institutions are often characterised by ineffective innovative management strategies and approaches that affect the provision of quality services.The aim of this study was to investigate innovative management challenges and measures necessary for enhancing health innovation in a quest for public service delivery improvement. The focus was based in the Limpopo Department of Health which served as a unit of analysis. The research utilised a qualitative approach with data collection methods, which included semi-structured interviews, focus group interview and document analysis. The semi-structured interviews included 52 participants selected through purposive sampling from various categories of management, clinical managers and community liaison officers within the Limpopo Department of Health. A focus group interview consisted of members of district health councils representing each district in the province. The documentary analysis included a consultation and use of official documentary sources such as departmental Annual Performance Plans (APPs) for the 2012/13 to 2016/17 financial years and departmental audit opinion outcomes issued by the Auditor General of South Africa as part of primary data sources. The findings of the study reveal among others, that there is ineffective innovative management caused by poor diffusion of innovations, lack of innovative management support structures and, lack of innovative management strategies and approaches within the Limpopo Department of Health. Furthermore, the study’s finding about lack of integrated innovative managerial functional areas motivated the researcher to propose the development of an integrated innovative managerial functions model for service delivery improvement. A development of such an integrated model is intended to harness health innovation efforts to key service delivery components within the public institutions, specifically in the Limpopo Department of Health.

- Description: The aims and principles of the post-apartheid South African school curricula, ranging from the Revised National Curriculum Statement Grades R-9 and the National Curriculum Statement Grades 10-12, to include the Curriculum and Assessment Policy Statements (Grades 1-12), have been aligned with the aims and principles of the South African Constitution. The aims and principles, among others, speak to the establishment of human rights, inclusivity, environmental and social justice, and valuing of indigenous knowledge systems. These are the bedrock of all the subjects and do not necessarily confine themselves to the science subjects only; even though the call of inclusion of indigenous knowledge in the sciences is oversubscribed. There has been concerns raised variously that the integration of indigenous knowledge systems in the curriculum, generally, and in the teaching of the respective subjects, particularly, does not necessarily happen as it should be. Thus, the purpose of this mixed methods approach study that adopted a concurrent triangulation mixed methods design and premised on the postpositivist paradigm investigated the integration of indigenous knowledge in the Intermediate Phase school curriculum in a selected Education District in the Eastern Cape Province, South Africa. The guiding lenses adopted for this study were two-fold. The main primary theoretical framework drew from three integration theories: (a) Huang and Newell’s (2003) Knowledge Integration Processes and Dynamics notions; (b) Beane’s (1995) Curriculum Integration and the Disciplines of Knowledge and (c) Harden’s (2000) Integration ladder: A Tool for Curriculum Planning and Evaluation. The ‘secondary’ lens of analysis, which the researcher named, the ‘supplemental framework’, was constituted by notions and constructs derived from the indigenous knowledge systems discourses and postcolonial notions and constructs. The study revealed, among other findings, that (i) whilst a majority of teachers claimed to integrate IK in their classrooms, a significant number did not, and those who claimed to be integrating were unsure about how to integrate (ii) the majority of teachers, HoDs and Subject Advisors were either poorly trained or did not receive any training in the integration of IK (iii) the support and monitoring of IK integration was poor to non-existent. Thus, the study proposes a model, the Integrative Indigenous Knowledge Integration Support and Monitoring Model (IIKISMM), which may act as a framework for the coordination of the support and monitoring of IK integration in the school curriculum. There are significant recommendations offered by the study to teachers and policy makers with regards the integration of indigenous knowledge systems in the school curriculum. Also offered by the study are possibilities for further research in the integration of indigenous knowledge system in the curriculum.

- Description: The concept that the family forms the foundation of our society is well established in national and international law.1 The family unit provides a child with a sense of security and identity.2 Moreover, the family as a unit plays a pivotal role in the upbringing of children, enabling them to develop to their full potential.3 Children who have inadequate or no parental care are clearly at risk of being denied such a nurturing environment. The large number of orphaned children following the devastating effects of World War II highlighted the serious need for countries to consider appropriate alternative placement for such children.5 Recognising the importance of the family unit, the Universal Declaration of Human Rights (UDHR) expressly acknowledges the family as the “natural and fundamental group unit of society”.6 Article 16 of the UDHR further states that the family unit is entitled to protection by the state and society.7 However, the vulnerability of parents, families and children has been intensified by recent global, regional and national developments, including the global economic crisis, devastating consequences of the HIV/AIDS pandemic, widespread poverty,8 unwanted pregnancies,9 child abandonment,10 rapid urbanisation, and the increased migration of adults and children into and within South Africa in search of economic and political refuge.11 In particular, the impact of the HIV pandemic on children in South Africa cannot be understated. South Africa has the largest percentage of HIV/AIDS-infected persons in the world, resulting in many children in South Africa being deprived of a family environment. The importance of family and the role it must play in caring for a child cannot be doubted, and both the national law of South Africa and international law bear testimony to this. Accordingly, it is understandable that the biological family remains the primary favoured unit of care for a child. Where, for whatever reason, the natural family fails or is unavailable to care for the child concerned, national and international law make provision for the care of an orphaned and/or abandoned child (OAC). Family forms are changing around the world, and South Africa is typical in several respects. Diverse family arrangements and household forms are recognised as providing a family-type environment for a South African child. In understanding the meaning of “family” in South Africa it must be noted that the family may extend beyond the biological parents of a child to a multi-generational network of people who are linked by blood, including grandparents, aunts, uncles and cousins. Relationship can also include non-blood relationships as in the instance of relationship through the ties of marriage or ties of co-residence. Whilst not exclusive to South Africa, it must also be noted in South Africa under apartheid regime, policies and practices were designed specifically to protect the nuclear family. The Department of Social Development (DSD) drafted the White Paper on Families and this was approved in 2013. The White Paper made conscious strides in granting recognition to a diversity of family forms in South Africa. It departed from the assumptions held of Western or nuclear families only as a norm. It is in light of this diversity that the concept “family” must be read in this research. Consideration of placing a child in appropriate alternative care must be contemplated in light of the context of the human rights movement and the development and recognition of the rights of a child in his or her own right.

- Description: This thesis sets out to contribute to the growing body of knowledge about queer sexualities and genders in Africa by examining their depiction in selected post-2000 African women’s short fiction written in English. Post-2000, the short story form has become the primary vehicle for queer representations by African women writers, and is thus an important development in the burgeoning body of queer literature by African writers. Broadly speaking, this literary formation can be defined as anti-homophobic, feminist and politically pragmatic. Using an intersectional lens, this thesis sets out to examine four significant strands in the political work these stories engage in. The chapters are structured around four main points of contention that have particular significance at the intersection of ‘queer’, ‘women’ and ‘Africa’. Firstly, I examine South African short stories that perform what I call queer conversations with history: imaginatively asserting a queer South African history, writing back against a male-dominated and heterosexist literary canon and, in doing so, contributing to the reimagination of the contemporary South African nation. Secondly, I analyse short stories from Africa that foreground the family, both as social formation and ideology. I examine how these stories ‘fracture’ this powerful and naturalised heterosexist concept by depicting the tensions and contradictions that queer characters experience in relation to family. Thirdly, I consider short stories from various African contexts that work to reconceptualise queer sexuality in relation to religious discourse in order to challenge homophobic and patriarchal religious authority. Finally, I examine queer, feminist erotic short stories by African women writers that challenges various colonialist, racist, sexist and lesbophobic discourses that have historically stifled the portrayal of sex and erotic experience between women.
