- Description: The researcher noted that earlier second language teaching models tended to treat language as an artefact to be scrutinised and adhered to with grammatical precision. This tended to reduce all language learning to the mere acquisition of grammatical skills. However, since all language behaviour is embedded in sociocultural and contextual frameworks, all teaching should provide cross-cultural awareness of that complexity as well as of the internal variation within language. Therefore, the research explored the interplay of sociolinguistic factors in the teaching of English in Zimbabwe. The Mixed Methods design; a combination of the descriptive survey and the case study was adopted. The questionnaire, interview, observation and document analysis methods were used to collect both qualitative and quantitative data to assess the role of sociolinguistic factors in second language teaching pedagogy. A combination of convenient sampling and stratified random sampling was used to come up with a sample representative of the school categories and the gender of teachers in the 38 secondary schools in Gweru District. The data for the research was collected from a random sample of 50 teachers. The data analysis supported the need for a reconceptualisation of ESL teaching in Zimbabwe. Notably, language teaching tended to be exam-centric, unimaginative and not well linked to the needs of the learners in the communicative environment outside the school. This confirmed the initial observation that the secondary school graduates generally lacked sociolinguistic competence skills. The teachers were, however generally not motivated to include culture and sociolinguistics in their teaching. The research therefore recommended a revisit of the 7 | Page allowance for the interplay of sociolinguistic factors at all the planning stages of the ESL curriculum; the status, corpus and acquisition stages.

- Description: Phylogenies may help to characterize transmission pairs, enhance contact tracing and outbreak investigations, track the origin and spread of epidemics over place and time, and to identify patterns of onward Human Immunodeficiency-Virus (HIV) transmission among risk groups. If the pattern and evolution of HIV drug resistance can be mapped, this may influence the development of guidelines in the clinical management of HIV especially with issues relating to prevalence of primary drug resistance and its impact on outcomes of present antiretroviral treatment (ART) regimen in use and the ability to trace and track the development of drug resistant strains. The roll-out of the test and treat Programme for newly diagnosed HIV infected pa-tient, seeks to identify HIV infected individuals early and to prevent morbidity and mortality associated with the late presentation for HIV care. The determination of the magnitude of ‘late presentation’ and or ‘presentation with advanced HIV disease’ can be used in very diverse settings and for many purposes. It provides a unified way to define the problem, thereby targeting appropriate interventions to prevent the detrimental outcomes associated with late presentation to care. The subtle relationship between HIV and diabetes mellitus (DM) may also help in formulating better preventive programs to aid the control of non-communicable diseases such as DM. This cross-sectional study includes a purposive selection of 335 HIV positive patients attending the voluntary counselling and Testing (VCT) and HIV Counselling and Testing (HCT) centres and outpatient departments at Cecilia Makiwane Hospital and the HCT sites at the Buffalo District municipality community health centres, Eastern Cape Province, South Africa. Late or delayed presentation of HIV infection was defined as CD4 cell count beneath 350 cells/μL and/or patients presenting with an AIDS-defining event at the first follow-up regardless of the CD4 cell count. Chapter 1 provides the general introduction had an overview of the introduction to the study, the statement of the research problem, hypothesis, the aim and the objectives. xx Chapter 2 looked in-depth at the HIV, case definition, the latest epidemiology of HIV, the HIV genome, the life cycle of HIV, its diagnosis, the classes of antiretroviral drugs, development of drug resistance. Chapter 3 highlighted the prevalence of Transmitted Drug Resistance (TDR) with focus on the protease gene. RNA was extracted from blood samples of 72 newly diagnosed HIV-1 patients attending some HIV testing and counselling clinics from August 2016 to July 2017. Protease fragments were amplified with specific primers by RT-PCR followed by nested PCR. The amplified products were sequenced using the ABI 360 sequencer, edited with Geneious version 9.1.5 and translated into amino acid with BioEdit software. Drug related resistance mutation (DRMs) analysis was performed on all the protease sequences in accordance with the 2009 WHO list of surveillance drug resistance mutations by submitting the edited sequences to Stanford HIV drug interpretation programme and the international AIDS society-USA guidelines for query of drug resistance associated mutations while phylogenetic analysis was performed using MEGA 6 to allocate all viral sequences into subtypes. In the study, a total of 52/72 (71.1%) reliable HIV-1 protease sequences were obtained in which subtyping and drug resistance mutations were performed. Two (3.8%) major Protease resistance associated mutation (V82A/L and L90M) were observed while another polymorphism like L10F, T74S, Q58E, L10I/V and M46V were also identified. Phylogenetic analyses delineated all the sequences as HIV-1 subtype C. Chapter 4 describes the prevalence and the determinants of late presentation amongst newly diagnosed HIV positive individuals in the Eastern Cape. It indicates the extent of the prevalence of patients presenting to care and at what HIV stage they were assessing health care services since the inception of the ‘test and treat’ strategy. It is a cross-sectional study where a total of 335 newly diagnosed patients were recruited consecutively be-tween August 2016 and July 2017. Late presenter for HIV care was defined in accordance with the European Late Presenter Consensus working group as a patient who reports for care when the CD4 count is below 350 cells/μL and/or when there is an established Aids- xxi defining clinical condition, irrespective of CD4 count. Adjusted and unadjusted logistic regression analysis was used to examine the determinants of late HIV diagnosis. The study showed that 60% of patients were late presenters, with 35% presenting with advanced disease. The major determinants identified were being male and low level of education. This led to recommendations directed at ensuring programmes that targets men in identifying their HIV status and assess care at early stage to prevents the morbidity and mortality associated with delayed presentation. Also, it was recommended that effort should be made to improve access to education and also include HIV related topics into the educational curriculum. Chapter 5 aimed to describe the prevalence and determinants of DM amongst newly diagnosed HIV positive individuals. This is a cross-sectional study which recruited 335 patients between August 2016 and September 2017. Definition for diabetes mellitus was made based on the SEDMSA 2015 guideline of HBA1C of above 6.5%. Adjusted and unadjusted logistic regression analysis was used to examine the determinants of abnormal glycated haemoglobin. Findings showed the prevalence of DM at about 6% amongst newly diagnosed HIV positive individuals. This is similar to findings in other study within the country, but a bit lower than what was obtained in the developed countries. The role of older age (above 40 years) as predisposing factor to development of diabetes in newly diagnosed HIV positive individual was well noted and taken. This ensures that screening for DM should be targeted at elderly HIV positive individuals. The grey area of the appropriate mode of diagnostic test to use to diagnose HIV is still debatable, however, a combination of HBA1c and fasting blood sugar (FBS) may improve the diagnosis of DM in this population group. In chapter 6, the general conclusions, recommendations and future perspectives of the study are reflected.

- Description: Despite the initiation of life-long ART in HIV-infected pregnant women, the rate and determinants of infant HIV transmission are not known, especially in the poor resource settings of the Eastern Cape, South Africa. Maternal anti-retroviral therapy (ART) is crucial for elimination of mother-to-child transmission (MTCT) of HIV. However, the inevitable risks of emergence of HIV drug resistance poses significant threat to achieving this goal of HIV-free generation and keeping mothers alive. Also, it is unclear if women with high viral load at delivery have acquired clinically relevant mutations, which could confer resistance to the ART, thus, further increasing the risks of motherto-child transmission of HIV-drug resistance strains. In addition to the gaps identified in the prevention of mother-to-child transmission (PMTCT) context, the understanding of regional epidemics is crucial to the broader epidemiological profiling of HIV infections in the country. Despite the rapid influx of foreign nationals to South African and Eastern Cape Province, there has not been any molecular epidemiological studies profiling the HIV diversity in the Eastern Cape.

- 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.

- 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: 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: A largely agricultural country, land remains an important factor of production and a critical element in the livelihoods of rural Zimbabweans. Small-scale farmers rely on land for food and income. The post-independence development of Zimbabwe has been tied to land holding. As such, land reform aimed at addressing colonial racial land inequalities and rural underdevelopment became an imperative. In the post-independence era, Zimbabwe undertook two phases of land reform – the first occurred between 1980 and 1999 and was known as the Land reform and Resettlement Programme (LRRP). This was based on the ‘willing-buyer and willing seller’. The second phase which took place from 2000, known as the Fast Track Land Reform Programme (FTLRP), took a radical approach. However, due to a variety of reasons, including the dominance of small-scale farming and challenges of land reform, agricultural productivity remains low. Moreover, despite land reform, including massive land redistribution, the process appears incomplete and inconclusive. This is so essentially because the land reform neither increased food production nor reduced poverty. Accordingly, sustainable development remains a distant reality, especially among rural small-scale farmers. The study aimed at assessing the impact of the fast track land reform (FTLRP) on poverty reduction and sustainable rural development in Zimbabwe. Despite undertaking one of Southern Africa’s largest post-colonial redistributive land reform to date, the provision of land on its own has not been sufficient to address rural poverty and achieving meaningful rural development. This is so because the land reform has not articulated integrated growth as remoteness and poverty remain endemic, which is connected to the land. So, resolving the land question still remains crucial for sustainable rural development in Zimbabwe.

- Description: Government promulgated the land rental policy starting in the year 2007. The policy required that A1 (market residual) and A2 (indigenous commercial) farmers pay rentals to the state. Since then, there has also been an emerging trend in which farmers have been renting in and out land, resulting in an informal market for land rentals. The study therefore assessed farmers’ perceptions of land rental policy and evaluated the possible association of this policy to farmers’ decision making on land rental markets as well as its implications on farmers’ efficiency and equity. The study was carried out in Mashonaland East Province of Zimbabwe, covering two districts, Goromonzi and Marondera. The focus was specifically on A1 and A2 farmers, as the rental policy was directed at these resettlement models only and much of the informal land rental markets were prevalent among these categories of farmers. Data collection utilised the survey approach. This was supported by key informant interviews and focus group discussions, with a final sample of 339 households selected using multi-stage sampling method. Survey data were transcribed on CsPro 6, and analysed using Stata, SPSS and Frontier 4.1. Results showed that about a third of household respondents was from Marondera and twothirds was from Goromonzi, while 79% and 21% was A1 and A2 farmers respectively. About 80% was male headed households and the remainder was female headed households. About half of the households were not participating in land rental markets while the other half was split almost equally between those renting-in and renting-out land. In general, A2 farmers were better in agricultural productivity than A1 farmers. It was concluded that farmers had a fairly good knowledge of the agricultural land rental policy enunciated in the Finance Bills. A1 farmers were more knowledgeable than A2 farmers, but no vii significant differences were observed between male and female headed households and farmers involved and not involved in land rental markets. Farmers’ attitudes in relation to policy were categorised as fair, with significant differences based on gender and land market participation. Practice scores showed a poor adherence to policy for all categories of farmers. Overall perceptions of farmers on rental policy was inferred as fair with significant differences existing between land rental market participants and non-participants (autarky). The results of a bivariate Tobit model results showed that the decision to rent-in land was significantly influenced by gender, household income, permanent labour, cultivated area, tenure certainty, irrigable land size and crop diversification. On the other hand, age, permanent labour, irrigable land size and crop diversification significantly influenced farmers’ decisions to rent-out land. The conclusion was that household characteristics, land endowments and transaction costs significantly influenced the decision to rent-in land while the former two were strong in influencing renting-out decisions. Results from the linearized Cobb Douglas model showed that economic efficiency for most farmers was above 50%. Farmers renting-out land under A1 were found to be the most economically efficient, followed by those who were renting-in and least efficient were farmers not participating in land rental markets, though the differences were marginal. For the A2 model, renting-in farmers were the most efficient, followed by those in autarky position, while renting-out farmers were the least. Overall, the most efficient farmers were those renting-in, followed by those renting-out while farmers in autarky were the least efficient. Overall efficiency was higher for A2 farmers than for A1 farmers. For farmers not participating in rental markets, the sources of inefficiency were crop type, crop area and labour. For farmers renting-in, it was proportion of irrigable land, size of irrigable land, crop type, crop area and viii labour, while inefficiency drivers for renting-out farmers were crop type and associated area. Equity analysis showed that participation in land rental markets reduced inequality for farmers in the two districts and male and female headed households. Inequality was increased among A1 farmers and remained unchanged among A2 farmers. Overall, the emerging position was that participation in land rental markets resulted in higher efficiency and reduced inequality in land holding among the sampled farmers. It is recommended that government should be consistent on land rental policy and bring into place effective administration of land rental policy. Government may also consider formal acceptance of land rental markets in light of the marginal efficiency and equity benefits shown in the study. However, formalizing land rental markets alone may not be a panacea to improved efficiency and needs to be supported by other productivity measures given the average efficiency values for farmers. Crop and livestock production based on compatibility with the natural regions and defined minimum size of land should be encouraged to improve efficiency

- Description: The aim of this study was to explore and describe the lived experiences of Xhosa mothers during the initiation period of their sons. The male rite of initiation among the amaXhosa has various taboos that prohibit women from getting involved in decision-making regarding the ritual. This creates a challenge as the number of female-headed households are increasing. The rationale for this study was to give Xhosa mothers a voice to relate their narratives of how they experienced the initiation period of their sons. In order to carry out this aim, the paradigm of Afrocentricity was used to anchor the study. Afrocentricity is a paradigm that supports the agency of African people in a study conducted about their issues. It also aims to give the previously oppressed groups a voice so that they can speak for themselves. Interpretative Phenomenological Analysis (IPA) as set out by Jonathan Smith was used as a qualitative research methodology in this study. Data was generated, recorded and transcribed from semi-structured interviews with eight selected participants. The biological mothers of Xhosa initiates, that experienced the initiation of their sons, took part in this study. The over-arching inclusion criteria were that the mothers gave permission for their sons to be initiated, and that their sons did not experience any major complications during the ritual. They met the inclusion criteria as set out by the researcher. The findings of the study indicated that the mothers’ experiences were multifaceted. They included the spiritual, psychological and emotional experiences, as well as their experiences as women, and, more especially, as mothers. The challenges that mothers faced during this period included lack of feedback regarding the health of their sons. This led to the experiencing of somatic symptoms like lack of sleep, poor appetite, and anxiety. In order to deal with their symptoms, the main coping mechanism that the participants used, was prayer. LISTENING TO SILENCED VOICES ii This study has highlighted the importance of listening to previously silenced voices in order to contribute to local knowledge. It is envisaged that the findings of this study will contribute to policy decisions that affect women, by ensuring the involvement of women in higher decision-making bodies. This is particularly important with the high number of femaleheaded households in the country.

- Description: This study evaluates how the Eastern Cape local web newspapers frame food security in the Eastern Cape Province. A qualitative content analysis by means of textual analysis was used to evaluate the selected local web newspaper’s content on food security related stories within the period of July-December 2017. The sample was drawn from four Eastern Cape local web newspapers- Daily Dispatch Live, Herald Live, Go and Express and The Talk of the Town. The analysis sought to determine how the selected local web newspapers frame food security concerning food availability, accessibility and affordability in the Eastern Cape Province. Additionally, the study aimed to ascertain the issues about food security that are raised by the Eastern Cape local web newspapers and, to establish the extent to which these Eastern Cape local web newspapers’ framing is helpful in ensuring participation, empowerment and community mobilization for food securing purposes. The results of this study indicate that the local web newspapers frame Eastern Cape Province as untapped food basket. The framing suggests that the Province can leverage its agricultural resources for job creation which will ensure economic growth and food security. The local web newspapers framing suggests that there are numerous channels such as natural food production, livestock production, smallholder farming that can enhance availability and access to affordable food to people in the Eastern Cape Province. The findings revealed that local web newspapers frame increased agricultural production as an important issue that demand serious and urgent attention of the Provincial government as it has the potential of not only ensuring food security but also impacting positively on the income of local farmers. The local web newspapers frame farm attacks, land redistribution and reinstatement as important factors that hinder food production and, ultimately, food security in the Eastern Cape v Province. Furthermore, this study discovered that the frame of references used by the local web newspapers, especially the emphasis on local farming, land redistribution and private sector help to empower and mobilize individuals and communities to participate in food security initiatives. This study concludes that Eastern Cape Local Web Newspapers can be veritable tools to enhance food security channels in the Eastern Cape Province

- Description: There is paucity of data on South African traditional healers’ (THs) phytotherapeutic practices regarding respiratory infections (RIs). Several people in South Africa are contracting RIs due to prevalence of risk factors. This situation is exacerbated by limited modern health care facilities and associated personnel in some provinces in the country. The primary objectives of this study were twofold. First purpose was to execute a comprehensive social and ethnobotanical surveys aimed at (a) establishing the types of RIs treated by THs and diagnosis techniques used, (b) plants used as therapies for RIs and associated indigenous knowledge practices, (c) source/s of plants used as medicines, (d) harvesting practices, current local availability status, conservation status and threats of indigenous plants as well as the level of conservation knowledge possessed by THs. The second objective was to assess the therapeutic value of the four most frequently used plant species by THs by (a) analysing the phytochemical profile of the plant extracts, (b) their antioxidant activities, and (c) their antibacterial activities. Information linked to the social and ethnobotanical surveys was gathered via a semi-structured questionnaires, supplemented by field observations during face-to-face interview with 240 conveniently selected THs practicing in the municipalities of Capricorn, Sekhukhune and Waterberg districts of the Limpopo Province, South Africa. Data were generally analysed using Microsoft Excel and Statistical Package for the Social Sciences (SPSS). In addition to these softwares, ethnobotanical data were analysed via quantitative ethnobotanical indexes namely use mention (UM), fidelity level (FL), use value (UV) and preference ranking (PR). For laboratory experiments, qualitative phytochemical constitutes of the crude extracts were determined using the standard screening methods. The antioxidant activities of acetone, dichlomethane, hexane, methanol and water crude extracts were evaluated using qualitative and quantitative 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assays. Antibacterial activities of these extracts was assessed using microdilution and bioautography assays. Six types of RIs; tuberculosis (84.1%), sore throat (65%), asthma (58.3%), sinusitis (55%), pneumonia (53.3%) and rhinitis (43.7%) were treated by THs practicing as herbalists (58.7%), herbalists and diviners (40.5%), and diviners (0.4%). The identification of these RIs was based on the patients’ presentation of certain clinical symptoms, with THs practicing both herbalism and divination additionally using bone casting. There was a broad overlap between the clinical signs used to diagnose most of the RIs, and the specificity of symptoms followed when ascertaining an individual infection was low. A total of 224 plant species (83% indigenous and 16.9% exotics) belonging to 177 genera and 85 botanical families, mainly the Fabaceae (25 spp.) and Asteraceae (16 spp.) were used by THs as herbal medicines for the aforesaid RIs and perceived related symptoms (RSs). Most of the documented plant species were used for tuberculosis (82.1%) and asthma (46.4%). Roots (64%) and leaves (13%) formed an important mainstay for medicinal recipes preparations. Different routes of administering these recipes were noted, with oral (75.6%) and nasal (18.8%) being the most preferred. The most widely used species by THs to treat and manage all the six RIs with high UM, FL, UV and PR values included Clerodendrum ternatum, Cryptocarya transvaalensis, Enicostema axillare, Lasiosiphon caffer and Stylochaeton natalensis. Overall larger numbers of species used by Bapedi THs including the mentioned ones are recorded for the first time in scientific literature as remedies for RIs and RSs, thus reflecting a need for more similar studies amongst other ethnic groups of South Africa and elsewhere. The phytochemical screening of four most used plants C. ternatum, C. transvaalensis, E. axillare and L. caffer crude extracts revealed the presence of alkaloids, anthraquinones, cardiac glycosides, flavonoids, phlobatannin, saponins, steroids, tannins and terpenes. All plants including those that did not display any antioxidant activities using qualitative DPPH assay displayed a certain level of scavenging activity when quantified, with the mentioned extracts from E. axillare (water and hexane), L. caffer (water and acetone) and C. ternatum (acetone) showing excellent activity almost comparable to a standard antioxidant drug (ascorbic acid). Plant extracts from all used solvents were active against Mycobacterium smegmatis, Klebsiella pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa with miniumum bactericidal concentration values ranging between 0.019 and 2.5 mg/ml depending on the plant species. Some of plant extracts exhibited minimum inhibitory concentration values ranging between 0.63 to 2.5 mg/ml. This study showed that most of the diagnosis methods used by Bapedi THs and their herbal medicines have the potential to contribute towards the management and treatment of RIs and RSs. iii | Page Future endeavour should be focused on the following: (a) possibility of collaboration between questioned THs and local western health care practitioners in the treatment of these diseases, and (b) isolation, purification and characterization of the biologically active compounds from extract of the above-stated plants, amongst other inquiries.

- Description: The main objective of this study was to determine the effect of muscle nanostructure on tenderness, fat colour related fatty acids and Check-All-That-Apply visual profiling of South African A2 beef longissimus. Fifty two A-class steers (n=52) of five breeds (Bonsmara (n=19), Beef master (n=7), Hereford (n=9) and Simbra (n=17)) typically processed in different South African feedlots were studied. The animals were humanely slaughtered at an abattoir following the commercial standard procedures. Fat colour measurements (CIE b*) were taken at the P8 site on hot carcasses at the abattoir. Carcass mass (warm and cold) was recorded at the slaughter line before chilling (warm) and after chilling (cold) while pH0 and temperature were measured at 45 minutes post-mortem on the Longissimus thoracis et lumborum (LTL) muscle. Thereafter, a 20 g subsection of the LTL muscle on the left side of each carcass was sampled for muscle nanostructure analysis. At 24 hours post-slaughter, ultimate pH (pH24) was measured, further subsections of the LTL muscle (20 g) were harvested for further muscle nanostructure analysis and 2.5 kg of the LTL muscle was also harvested for analysis of tenderness, fatty acids and sensory evaluation. The muscle nanostructure (myofibril diameter (MYD), myofibril spacing (MYS), muscle fibre diameter (MFD), muscle fibre spacing (MFS) and sarcomere length (SL)) was analysed using the scanning electron microscope (SEM) while tenderness was measured using Warner Bratzler Shear Force after 45mins, 24hrs, 3 and 7 days aging period at -20 ºC refrigerator temperature. Some proximate fractions (total extractable intramuscular fat (Fat %), Fat Free Dry matter (FFDM %) and Moisture content) and fatty acid profile were measured using extracted fat and fatty acid indices (desaturase index, atherogenicity index) were calculated. Lastly a Check-All-That-Apply visual profiling method rated by an 80-member consumer panel was done to assess consumer meat preferences and perceptions of Bonsmara, Hereford and Simbra A2 fresh steaks. At 45mins post-slaughter breed affected (P<0.05) MYD and MYS, while at 24hrs breed affected MFD and MFS only. Early post-mortem pH (pH0) had no effect on the muscle nanostructure and tenderness while ultimate pH (pH24) affected MYD and MYS only. Muscle temperature at 45mins affected (P<0.05) the MYD, MFD and MFS, while 24hrs muscle temperature affected (P<0.05) MYD only. Tenderness was not related to the muscle nanostructure early post-mortem and there was no uniformity on the changes in muscle nanostructure and tenderness from early post-mortem to 24hrs against the multifaceted carcass mass, muscle pH and temperature effects. During ageing, breed affected the MYD and MYS at 45mins, while at 24hrs in addition to the myofibril structure breed also had an effect on muscle fibre bundle characteristics (MFD and MFS). The changes in MYD, MYS and MFS became constant on day 3 while variations in the MFD still progressed. There was no uniformity on the SL pattern during ageing and a very weak linear relationship between tenderness, SL, MFD and MFS was observed. Notably there was also no uniformity on how the muscle texture features; including the surface structure, fibre separation, and the mechanism of muscle contraction and relaxation; changed throughout the ageing period across and within the breeds. Moreover, breed had a significant effect on pentadecyclic acid, total saturated fatty acids (SFA) and docosahexanoic acid. Differences (P<0.05) in SFA, monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), n-6, n-3, fatty acid ratios, and desaturase index were observed among the white, creamy-white and creamy fat colour. The distribution of fatty acid classes was SFA>MUFA>PUFA in descending order of concentrations of mean values (44.19:40.06:15.75, respectively), while the n-6: n-3 ratio was 12:1. In sensory evaluation, consumers indicated how they would prefer to pay premium for meat with guaranteed muscle and fat colour, low fat content, high marbling and tenderness. Consumers observed breed differences (P<0.05) in muscle fibre separation and muscle colour. The overall liking of each attribute was more on moderate bright cherry red lean colour, moderate yellow fat, very abundant marbling and slight separation of muscle fibres. Differences on discrete liking of each attribute among consumers had an effect on the overall liking of each steak with Hereford steaks being more preferred by consumers. It was concluded that meat from beef animals within the same feeding regime has a different fatty acid composition owing to different breed synthetic pathways and feed ingredients and that meat tenderness is not affected by the muscle nanostructure early post-mortem. However, during ageing, meat tenderness is directly linked to breed related myofibril structure changes in particular the myofibril diameter, spacing between myofibrils and their interaction; while the muscle texture features, fibre diameter, spacing between muscle fibres and sarcomere length explain the non-uniformity of beef tenderness. Also the organoleptic and health related quality of meat assumed more importance among consumers in sensory evaluation. Thus meat classification systems should include more credence aspects or indicators that support credence quality of meat

- Description: Meat processing at the abattoir provides meat by product and waste while, the major part of the muscle which constitutes a third is edible. The edible by products (EBP) of meat have a notable position in our day-to-day life and are used in diverse forms. However, the quality of offal meat may differ according to intrinsic and extrinsic attributes that may occasionally be shaped by the attitude of consumers towards the products. Therefore, the first objective of this thesis focused on features that might influence consumer preferences and their perception of offal meat. A total of 202 consumers from three Municipalities in Amathole District were randomly sampled using exponential nondiscriminative snowball sampling. Data were gathered through a structured questionnaire containing open ended and closed ended questions. The study showed that consumers were more influenced by the freshness, price and availability of the product and these factors are used to determine the purchase outlet. Differences were observed in the offal meat consumption between the age groups. Age groups 25-34 (29.7%) and 35-44 (27.4%) showed the highest offal meat consumption, while the decline was observed in age groups of 55-64 (11.9%), 65- 74 (5.9%) and 75-85 (0.01%) respectively. The most preferred purchase point for offal meat in this study was in butcheries. However, it was observed that the factors influencing offal consumption in Amathole District were similar to meat consumption except that, offals were mainly purchased at butcher shops. The second objective in this study was to determine the sensory characteristics and consumer acceptance of sausages with 10% fat, 30% edible meat waste and 50% edible meat waste. Sensory descriptive attributes such as appearance, texture, colour, taste, flavour and overall acceptance of the sausage were evaluated by sensory panel (n = 60). The sensory panel comprised of students from undergraduates, post-graduates, post-doctoral fellows and lecturers at the University of Fort Hare. The findings of the study indicated that 50% replacement of xiii edible meat waste was similar to the commercial 10% fat with regard to several sensory attributes and pooled liking. Therefore, the utilization of the edible meat waste in production of sausages has the potential to increase profitability in meat industry and minimise meat waste in the industry. However, the cooking method that was more acceptable to consumers in this study was using the microwave as compared to oven-grilling. Furthermore, the effects of different cooking methods (microwave and oven-grilling) on proximate and mineral composition of the formulated sausages were determined. However, the cooking process appeared to have a significant effect on most of the minerals in the sausage. The cooking methods had a significant effect at P <0.01 on the nutrients composition of the formulated sausage. It was observed that the nutritional values of the sausage was better preserved after the cooking process due to higher mean values obtained after cooking. The mean values for calcium (173.1, 221.76, 231.29), potassium (444.57, 158.58, 156.67), magnesium (84.43, 257.97, 127.27), zinc (52.94, 35.27, 27.13), copper (8.8, 7.07, 4.44), manganese (8.74, 0.65, 0.08), sodium (589.42, 604.45, 529.79) and iron (63.3, 85.38, 74.81) in cooked. And the mean values for calcium (286.18, 132.18, 114.79), potassium (206.64, 113.83, 207.81), magnesium (189.89, 33.97, 48.11), zinc (61.05, 28.09, 26.44), copper (2.92, 2.73, 3.89), manganese (1.42, 0.11, 0.35), sodium (566.47, 530.79, 527.35) and iron (77.56, 58.68, 45.42) in uncooked sausage varied greatly among the treatments. Although, the disparities in the mineral content may be attributed to the different edible meat waste from different parts of the cattle which are either from feedlot or pastured based. In regard to the results obtained from proximate and mineral composition, microwave cooking method was found to be the best cooking technique for healthy eating. Finally, the effect of frying with two different oils (sunflower oil and olive oil) on the fatty acid composition of sausage made with edible meat waste was examined. The results revealed that beef sausage containing 70% edible meat wastes and 30% beef (T1) had a higher fat content xiv (25.7%±0.83%) than other treatments. On the other hand, beef sausage fortified with 10% fat and 90% beef (T3) had the lowest fat content but highest FFDM (55.85±0.57%) and moisture content (69.15±0.62) than other treatments. Despite the increase in omega-3: omega-6 fatty acid ratio in the sausage treatments after cooking, the mean value of omega-3: omega-6 fatty acid ratio was greater than 1:5 (0.2) which is within the FAO/WHO recommended range. The omega-3: omega-6 association is well-known for its importance in the diet because it is a key factor for balanced eicosanoid production in the living organism. The significant reduction in saturated fatty acids after cooking showed that there could also be a positive influence on the human health if consumed. Therefore, it may be concluded from the findings of the study that sausage made with edible meat waste as fat replacer is safe for human consumption.

- Description: In South Africa, computational ontologies have gained traction and are increasingly viewed as one of the viable solutions to address the problem of fragmented and unstructured nature of indigenous knowledge (IK) particularly in the marginalized rural communities. The continual existence of IK in tacit form has impeded the use of IK as a potential resource that can catalyze socio-economic and cultural development in South Africa. This study was, therefore, designed to address part of this challenge by developing a Xhosa Beadwork Ontology (XBO) with the goal of structuring the domain knowledge into a reusable body of knowledge. Such a reusable body of knowledge promotes efficient sharing of a common understanding of Xhosa Beadwork in a computational form. The XBO is in OWL 2 DL. The development of the XBO was informed by the NeOn methodology and the iterativeincremental ontology development life cycle within the ambit of Action Research (AR). The XBO was developed around personal ornamentation Xhosa Beadwork consisting of Necklace, Headband, Armlet, Waistband, Bracelet, and Anklet. In this study, the XBO was evaluated focused on ascertaining that the created ontology is a comprehensive representation of the Xhosa Beadwork and is of the required standard. In addition, the XBO was documented into a human understandable and readable resource and was published. The outcome of the study has indicated that the XBO is an adequate, shareable and reusable semantic artifact that can indeed support the formalization and preservation of IK in the domain of Xhosa Beadwork

- Description: The research sought to analyse how patriarchal perceptions have affected women in Zimbabwean national politics with specific focus on women politicians in Matabeleland region. The researcher observed that women politicians in this region seem to face multiple oppressions and yet seem to have been excluded in previous studies. The mixed method approach was adopted for the research. Questionnaires were used for the quantitative method, while key informant interviews and focus group discussions were utilised for the qualitative method. Findings from the survey revealed stereotypical perceptions such as that men are better leaders than women, women are not capable of holding decision making positions and the perception that politics is not safe for women. The findings from the key informants indicate that women politicians in Matabeleland face quite a number of challenges emanating from these patriarchal perceptions. The challenges include violence, humiliation and cultural stigmatization. Although women have attempted to resist patriarchy, it seems that the resistance has not been enough to eliminate the patriarchal mentality and the oppressions that accompany it. The research adopts a combination of feminist and intersectionality theory as a framework for analysis of the problem under investigation. The research potentially contributes to academic discourse by advancing literature on the multi-faceted aspects of patriarchy. The study recommends psychological and financial empowerment of women, electoral reforms and criminalization of offenders. The implementation of proper reforms and corrective measures envisage the long-awaited new dawn among women whom since time memorial, have been suppressed by deep-seated societal and patriarchal beliefs.

- Description: South Africa was listed amongst the countries with a percentage of students with achievement too low for estimation by “Progress International Results in Reading” in 2011. Meanwhile, there was also an indication that, high school learners in the Eastern Cape Province are highly challenged, as far as their ability to produce speech, as well as the ability to interpret meaning beyond what is literally suggested. Since such difficulties usually pose problems of content understanding, concerned researchers in the field of language took it upon themselves to investigate the underlying cause of the problem, in order to prevent more problems of pragmatics incompetence, such as, problems with social interaction that could retard one’s ability to function independently as an adult. While many studies have been conducted in the area of Pragmatics language competence, this study found it necessary to contribute around this debate. Since the study was two-fold, isiXhosa Home language learners of Grades 10 to 12 were investigated with an objective to determine the extent of pragmatic incompetence and the Teachers were investigated to determine the effectiveness of their teaching of pragmatics language. A number of 108 high school isiXhosa learners, of ages of between 16 and 18 years, from East London Directorate, 36 per Grade, from the three selected schools high schools, were sampled, 36 consisting of 18 males and 18 females per grade from each selected high school. 9 isiXhosa Home Language teachers of between the ages of 45 to 54 years were sampled from the selected schools. This study used an assessment test for the learners and the questionnaire for the teachers, as a means of data collection techniques. The study applied a high consideration of validity as well as of ethical matters in order to ensure the reliability of results. The study found that, isiXhosa Home language learners’ levels of pragmatic competence are high and with the appropriate use of good methods of pragmatics language teaching, learners’ pragmatics competence can develop.This study will be able to encourage syllabus designers to collaborate with subject teachers, beginning right at the inception of the syllabus planning. IsiXhosa language teachers can develop teaching material appropriate for their primary goal, which is the development of pragmatic competence. Further research is recommended to investigate more around this area of study to a point where isiXhosa Home language can be counted amongst the great and valued languages of South Africa.

- Description: Music, before and after independence in the former colonies, has been playing a central role of articulating national concerns. It became an alternative medium through which historical narratives were channeled out to the public. While many scholars have acknowledged the critical role of music’s attempt to whip the autocratic governments into line, and the attempts by the governments across the world to thwart the critical/activism role of music, little emphasis was put on the mechanism of circumventing censorship, the linguistic competence (or lack of it) of music in conscientising the public on national issues. This thesis aims to harness this seemingly entertainment tool (music) into serious academic discourse by looking at the way power relations and ideological contestations are symbolically reflected, represented and communicated in popular culture, in particular the Zimbabwean Sungura and Chimurenga music. It makes a critical analysis of the diction of music as it attempts (or fails to) reflect and represent the Zimbabwean historical narratives from the early 1990s to 2008. The study tries to (semiologically) fracture the musical lexicon and the ideological stance on which it is based to show the extent to which music communicates by way of reflecting and representing the Zimbabwean historical narratives. The thesis looks at how popular music has ‘become the most prominent signifier’ and at ‘the shifting meanings and the significance of … music’ (Nooshin 2005:231) in Zimbabwe. It utilises a qualitative research approach specifically an interpretive prism. Key research methods for the study include in-depth semi-structured interviews which were conducted with purposively selected informants such as university academics and two of the selected musicians. The selected academics were purposively sampled basing on the researcher’s knowledge of their inclination towards Cultural Studies, particularly popular culture. The study has managed to bring clarity to the research questions in a big way considering the application of the various theories that framed the thesis discussion. Research findings indicate that interpretive semiotics aids to unpack the philosophy of meaning making through song. Music as a medium has the reflective effect of a mirror and a photographic effect of a camera to enunciate the ideological innuendo in the leader-led dichotomy. The study shows that protest popular music rejects knowledge that affirms the status quo; it is counter hegemonic and seeks to regenerate selfhoods and self-liberation amongst the subaltern class.

- Description: This study analysed the use of social media platforms, WhatsApp and Facebook in monitoring human rights ahead of Zimbabwe’s 2018 Harmonised elections. Zimbabwe has witnessed gross human rights violations since the attainment of independence in 1980 but most of these violations have been misrepresented, partially captured or ignored particularly by the partisan state media. While issues of human rights have been researched on, there has been a gap in research on the role of social media in safeguarding human rights in Zimbabwe, particularly during election times. There has also been a gap in research about the influences of social media, not just to inspire revolutions but to strengthen democratic practices in Zimbabwe through vibrant discussions of human rights issues on social media platforms. This study was informed by Habermas Theory of public sphere and Social network theory in order to analyse texts shared and discussed on WhatsApp and Facebook about human rights committed ahead of 2018 Harmonised elections. The aim was to establish use of social media as watchdog of human rights. A qualitative content analysis was applied to study texts shared on WhatsApp and Facebook about human rights violations across the country. Three WhatsApp groups and seven Facebook pages were selected for the study from which posts and responses from participants were extracted for analysis. The findings of the study revealed that social media can effectively strengthen democratic practices by exposing government’s unconstitutional practices. Further, social media can be useful in offering ordinary citizens a platform for engagement with civic society as they discuss issues that affect them. The findings of the study also hold the state accountable for the majority of human rights abuses committed throughout the election campaign period. The study then recommended that the government of Zimbabwe should go back to constitutionalism and abide by international human rights treaties to which they are signatory. Further, the study recommended that Zimbabwe Human Rights Commission and other independent commissions be empowered so that human rights are fully enjoyed in Zimbabwe, not just during election campaign periods but all the time

- Description: The study investigates South Africa-based Diaspora movements and their pursuit of democratic consolidation in Zimbabwe. The study is a qualitative one and made use of both primary and secondary sources. Primary sources included in-depth interviews, Facebook and Twitter posts, whilst secondary sources included textbooks and online journals. The study is premised on both the Political Process and Critical Theories. The study acknowledges that CSOs in general are important key players and have been identified as one of the major actors capable of helping in consolidating democracy. Zimbabwean Diaspora movements have been on the rise due to the mass exodus of its citizens to South Africa following economic collapse and civil strife in the country. The study found out that the civil society and political space in Zimbabwe is mired by partisan use of state security forces, repressive legislations, abuse of human rights and politicisation of the judicial system. These notwithstanding, the study reveals ZEF, CiZC and ZRYM have played their part in trying to consolidate democracy in Zimbabwe from their base in South Africa. They have employed various strategies and these include submitting petitions, advocacy and lobbying, partnerships and dialogues and making use of the Social media. Some of the breakthroughs recorded include educating Zimbabweans and disseminating information through social media, raising awareness and contributing to policy formation. The study, however, notes that apart from their achievements, they have also faced challenges like inadequate resources, xenophobia, leadership crises and donor fatigue. Key findings inferred that strategies used did not yield desired outcomes, and challenges faced made consolidating democracy in Zimbabwe a daunting task. The study recommends that partnerships between the Zimbabwean government and Diaspora movements need to be introduced and sustained in a way that catalyses a relationship where discussions can take place for democracy to be consolidated in Zimbabwe without any form of hostility from the government

- Description: The goal of the study was to examine teachers’ beliefs and classroom practices about their corrective feedback strategies in selected peri-urban rural schools in Umguza District in Zimbabwe, in order to draw up a Corrective Feedback model aimed at enhancing ESL proficiency among O’ level school pupils. The study has been necessitated by challenges which post O’ level students face when communicating in English at institutions of higher learning. The study used the mixed research approach, whereby both quantitative and qualitative methods of gathering data were used though the dominant approach was the qualitative approach. Data was collected through questionnaires, semi structured interviews, lesson observations and examination of pupils’ written exercises. The questionnaire was completed by twenty two teachers. Semi-structured interviews were held with six teachers from the selected schools, while nine lesson observations were done and eighty exercise books were scrutinized for the presence of written Corrective Feedback. Results obtained showed that teachers’ stated beliefs about corrective feedback were not always demonstrated in their classroom practices. Furthermore the study revealed that oral Corrective Feedback was not used consistently in addition to a lack of uniformity in both the usage and interpretation of written Corrective Feedback. Results obtained showed that teachers’ stated beliefs about Corrective Feedback were not always demonstrated in their classroom practices. In addition, the study also revealed that some teachers were not aware of the codes used in written Corrective Feedback and their meaning. The conclusion reached in this study was that vi there is need for a more informed and consistent usage of Corrective Feedback among teachers. In the light of this finding, a Corrective Feedback model was suggested to assist teachers apply Corrective Feedback more consistently and more productively. A number of recommendations were made at the conclusion of this study. Firstly, it was recommended that marking codes be availed to teachers and pupils before the beginning of the school calendar. The contents of the advisory chart included in this study could be given to pupils to copy onto the back of their exercise books to enable them to interpret the feedback which the teachers would have written. It was recommended that teachers familiarise themselves with the developments in the use of CF in the ESL classroom. At school level this could be done through staff development workshop, where teachers share experiences about what works and what does not work in the ESL classroom. This should be done in view of the existing problem of communicative incompetency bedevilling pupils nationally. Secondly it was recommended that teachers familiarise themselves with the developments in the use of CF in the ESL classroom. The final recommendation was that teachers adopt minimal marking in the form of codes in order to cut down on turnaround time as well as stimulate individual learner automatisation of knowledge.
