- Description: The main aim of this study was to investigate the status of records management programme at Walter Sisulu University (WSU) using the Nelson Mandela Drive Site of Mthatha Campus. In carrying out this study, four research objectives with thirtyseven (37) research questions were posed. Purposive Sampling was employed to sample 30 Administrative support staff. The instruments used for data collection were questionnaire and face to face interview. Twenty-nine (29) questionnaires out of the thirty (30) returned completed and five senior managers were interviewed face to face. Descriptive statistic was used to analyse the research questions on the questionnaire and thematic approach was used for analysing the response from the interviews. The major findings of the study revealed WSU fell below the requirements in terms of records management programme on maintaining records that document its business activities. Inadequate infrastructure, inadequacy regarding the desirable control of WSU records at each stage as required by the records life cycle framework was also found to be inadequate and limited knowledge of legal requirements regarding records management. Based on these findings, the following recommendations were made. Effort should be made to implement a Centralised control of Decentralised Registry System (Integrated Registry System), provision of training of staff, as well as proper infrastructural facilities.

- 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: Regional financial integration (RFI) is perceived as the other avenue through which the financial sector of member countries can develop given the vast benefits which associated with it. These benefits include mobilization and allocation of efficient resources to productive sectors within the region which plays a very important role in the development process. Given this background, the study examines how regional financial integration promotes financial sector development in the SADC region utilizing the panel data model for the period 1996 to 2015. The empirical results revealed that regional financial integration does have an impact on the financial sector development in the member countries in the region. Furthermore, the results showed that regional financial integration require a certain degree of institutional quality for RFI benefits to accrue. The empirical results imply that the countries in the SADC region should pursue regional financial integration. This can be achieved through commitment by all authorities in the region. There should be a firm commitment to broader economic integration and building on existing networks and build the necessary infrastructure.

- Description: Adverse childhood experiences (ACEs) are of great concerns in public health. They are traumatic experiences that occur during childhood. ACEs include various forms of abuse and maltreatment which can be emotional, physical, verbal and sexual, different degrees of household dysfunction such as growing up with substance abuse like drugs and alcohol, witnessing domestic violence, mental illnesses, crime in the home and parental disharmony. Although childhood adversities and traumatic experiences occur before the individual is 18 years of age, the effects of such experiences can last a lifetime causing mental and chronic medical illnesses. Resilience is perceived as an antidote to the detrimental effect of ACEs. It is a situation in which an individual displays a high level of effectiveness after a significant misfortune or adversity. This study was conducted to assess the level of resilience towards adverse childhood experiences among public secondary school children in Alice. Data were collected with the aid of a wellstructured questionnaire from 418 public high school students using Convenience sampling method. Factors influencing resilience among the learners were examined. Consequently, the data collected were analyzed using descriptive statistics and ordered logit regression model. From the results, it is observed that the majority of the learners live with their grandparents and the most prevalent form of ACEs is emotional abuse, followed by sexual abuse while community violence is the least common childhood adversity. This study further reveals that some of the respondents experienced more than one form of adverse childhood experience. In addition, irrespective of what the students have been through, they are largely observed to be resilient. Analysis from the ordered logit regression model shows that age, class in school, gender, religion, race and who the student lives with are significantly related to resilience. The study, therefore, recommends a functional counseling unit in the schools while student-teacher relationship must be encouraged

- Description: In Primary Health Care system there are different categories of nurses that have different roles to play within their facilities, such as registered nurses, enrolled nurses and enrolled nursing assistants, operational managers at functional level within the Primary Health Care Clinics and also overall supervisors. The study focus was on operational managers as they are the key role players in quality client care within Primary health Care clinics, King William’s Town in Buffalo City Health District in Eastern Cape Province. The aim of the study was to describe the role of nurse managers in ensuring client satisfaction within the Primary Health Care Clinics at Buffalo City Health District in order to ensure effectiveness of Health Core Standards. The research questions were: The research questions that was addressed in this study Main question: “What is the role of nurse managers in ensuring client satisfaction within Primary Health Care Clinics at Buffalo City Health District?” Sub questions: How do you ensure client safety in your facility? How do you monitor client waiting time in your facility? What strategies can assist in the improvement of client satisfaction in Primary Health care clinics? The objectives were to explore and describe role of nurse managers in ensuring client satisfaction regarding safety within the Primary health Care clinics in Buffalo City Heath District, explore and describe role of nurse managers in client satisfaction about waiting time within Primary Health Care Clinics and to recommend strategies to improve client satisfaction within the Primary Health Care clinics in order to improve client satisfaction. A descriptive, explorative, qualitative, contextual design was used to describe and explore the role of operational manager in ensuring client satisfaction regarding client safety and waiting time within Primary Health Care Clinics. Purposive sampling method was used to select seven operational managers. Six operational managers participated in the study as one of them was bereaved during the interview period. One on one interviews with operational managers was used to collect the data. Data was collected until it reached saturation. Data collected was analyzed using Tesch’s steps of data analysis for qualitative research. vi The results were that the operational managers are performing their roles, but find it difficult to fully satisfy clients as they experience some roles’ related challenges in ensuring client satisfactory services. Related roles’ challenges were unavailability of enough nursing staff to cover all the programmes due to shortage of staff, poor infrastructure in some of the clinics, lack of support and appreciation from some of their supervisors, absenteeism of staff that negatively affect operational manager’s planning and organisation role, failure to deliver medication in time. They recommended some strategies regarding improvement of client satisfaction within the Primary Health Care clinics. The recommendations were, the department of health to fill in nurses and staff vacant posts, facilitation of prompt delivery of medication to Primary Health Care Clinics, the department to attend to poor infrastructure, District office to consider staff satisfactory survey, commitment of clinic supervisors in their monthly visits and the study findings be used when conducting further studies related to ensuring client satisfaction regarding safety and waiting time

- Description: In order to formulate or implement relevant food security programmes in rural areas, it is important to have a deep understanding of the food security status of rural households. Accordingly, this study was conducted to assess the food security status of rural households in Raymond Mhlaba Local Municipality. The study also sought to identify the socio-economic characteristics that influence household food security status. The research relied on primary data. Primary data were collected by using a structured questionnaire, which covered both demographic features of respondent households, and their recent food consumption patterns. The household survey was conducted among 272 participants of Raymond Mhlaba Local Municipality. Statistical tools employed in this study included both descriptive and inferential statistics. The main descriptive statistics used were frequency tables, means and percentages in relation to a number of demographic characteristics and food security indicators. The main indicator of food security/insecurity used in the study was the Household Dietary Diversity Score (HDDS). After calculating the HDDS for each household, households were defined as either food secure or insecure depending on whether their HDDS was above or below the average HDDS. A logistic regression model (binary or dichotomous) was then used to identify socio-economic factors that influence some households to have above-average rather than below-average food security levels. The Binary logistic regression model revealed that four out of eight variables included in the model were significant in explaining the variation in the food security situation of households in the study areas, namely age of household head, education level of household head, household income and household size. Of these, the first three were positively associated with aboveaverage food security status, while household size had a negative association. A Tobit model was further used to identify the determinants of the household dietary diversity score. The exact same variables were significant from the Tobit analysis, and in the same manner.

- Description: The aim of the study was to establish a deeper understanding on the stratigraphy, sedimentology, petrology, organic geochemistry and diagenesis of the Ecca Group, and to provide new insight on the shale gas occurrence and potential of the Ecca Group, Karoo Supergroup in the southern Karoo Basin. The Ecca Group stratigraphy is divided into five formations from the bottom upwards, namely the Prince Albert, Whitehill, Collingham, Ripon and the Fort Brown Formations. The stratigraphy of the five studied stratigraphy’s formations is now sub-divided into two new different members each. These subdivision was based on field investigation of lithological features, sedimentary structures, facies characteristics and stratigraphic correlation points. Each member has been assigned a lithological name. Sixteen sedimentary facies have been identified in the study area and were subdivided into six distinctive facies associations (FA 1, FA 2, FA 3, FA 4, FA 5 and FA 6). Sedimentological characteristics of facies associations identified indicate that the Ecca Group sediments initially accumulated in a deep marine environment, progressed through turbidite, shallow marine and ended in lacustrine and deltaic environments. The stratigraphic succession of the Ecca Group constitutes a perfect regression sequence, indicating that the marine water gradually retreated and the sea-level gradually dropped. Grain size analysis was performed on twenty four Ecca Group sandstone samples. Statistical parameters of grain-size statistical parameters, linear discriminate functions, passega diagrams and bivariate analysis were used to reveal the hydrodynamic conditions and depositional environments. The results indicated that the Ecca Group sandstones are mostly fine to very fine grained, near-symmetrical, mesokurtic and indicative of dominance of low energy environments. The linear discriminate function analysis for the Prince Albert, Whitehill, Collingham and Ripon Formations samples indicates that the majority of the deposits were by turbidity currents all in a deep marine environment; whilst of the Fort Brown Formation samples are lacustrine/deltaic deposits. The depositional mechanism C-M plot indicates that majority of the Ecca Group sediments clustered in the PQ and QR field suggesting deposition mainly by suspension, rolling or saltation as well as graded suspension. Modal mineral composition analysis indicates that the main framework grains of the Ecca Group sandstones are quartz, feldspar as well as lithic fragments derived from metamorphic, igneous and sedimentary rocks with a few from volcanic origin. The Ecca Group sandstones iii are immature compositionally and can be classified as feldspathic wackes and lithic wackes. The QFL ternary diagram revealed a dissected and recycled orogen arc provenance; whereas QmFLt ternary diagram point to dissected arc and transitional arc sources to an active continental margin as well as recycled provenance. These provenance characteristics suggest a metamorphic and plutonic terrains influence as the main source rock with minor debris derived from recycled sedimentary rocks. The weathering diagram and semi-quantitative weathering index suggests that the sandstones from the Ecca are mostly from a plutonic source area under arid to humid climatic conditions. The detrital modal compositions of these Ecca Group sandstones are related to a strike-slip setting, back arc to continental margin setting. Diagenetic features of the Ecca sandstones and shales are subdivided into early, late (burial) and uplift-related diagenetic stages. Mechanical compaction, recrystallization, cementation, replacement and the dissolution of framework grains or cements are some of the main diagenetic processes that largely affected the Ecca sediments. Early diagenetic processes include cementation, point/planar contact, formation of pyrite, hematite cements and mineral inversions. Recrystallization, replacement, compaction, overgrowth, albitization, seritisation, illitization, concave-convex and suture contacts as well as dissolution took place mostly in the later diagenetic stage due to increase of temperature and pressure as burial depth increased. The uplift-related diagenetic stage was mostly affected by deformation and fracturing, calcitization, dissolution, erosion and weathering. Diagenetic processes largely affected the porosity and permeability of the reservoir rock properties of the Ecca Group. Organic geochemistry results indicate that the sediments were highly weathered and the TOC values ranging from 0.10 to 7.35 wt% with mostly less than 0.5%, which indicate the source rocks have poor oil potential. The majority of the Ecca Shales have HI values less than 50 mg HC/g, TOC indicating Type-IV kerogen mostly derived from reworked organic matter with very little hydrocarbon generation potential. The relatively high Tmax (oC) and vitrinite reflective values indicate that most shales are thermally over-matured thus they have low hydrocarbon pontential.

- Description: The popularity of mobile technologies has greatly influenced the people of all ages, especially adolescents. Tablet computers as part of mobile technologies, were launched in colleges and universities in many countries to supplement and complement learning and teaching. However, research reports based on the effectiveness of the use of tablet computers in higher education institutions in South Africa’s Eastern Cape Province are scarce. In order to address the deficiency, this study examined the views of stakeholders such as students, lecturers and managers on the use of tablet computers for learning and teaching in one of the Eastern Cape universities. The research adopted the Post-Positivist paradigm and mixed method approach. The theoretical frameworks were Constructivism and Technological Pedagogical Content Knowledge. The sample consisted of (a) 155 students from a population of 254 extended-stream National Diploma students in Information and Communication Technology and National Diploma Electrical Engineering cohorts; (b) 14 lecturers from a relevant population of 25; and, (c) 16 managers from a population of 20. Three separate questionnaires as well as interview protocols for each of the stakeholder cohorts provided the core data. All members in the sample were surveyed. The researcher opted to be an outsider and received assistance from a few qualified trained academics to administer the questionnaire to students in different cohorts in order to minimise data bias. Only 18 students, five lecturers and nine managers were interviewed. Quantitative data were captured manually into Statistical Package for Social Sciences (version 24) and they were analysed using descriptive and inferential analysis: Analysis of Variance and Independent Samples t-test. Qualitative data were transcribed and analysed using thematic analysis to generate major themes and sub themes for the sub-research questions. Main strengths of using tablets from the findings of the study were (a) tablets motivated students in learning and lecturers in teaching (b) students understood the different styles of learning (c) enhanced students’ engagement and collaboration in learning. Main weakness of using tablets were students’ use of tablets for personal work and social networking during class hours was causing distractions to lecturers and other students. Generally, the evidence shows that strengths were greater than the weaknesses. It should also be noted that all stakeholders were positive and not statistically significantly different from each other in their views towards the use of tablets for learning and teaching in university classroom. However, students had views different from lecturers on the advantages and disadvantages of using tablets. The variance could be due to new students or new lecturers’ ignorance in the effective use of tablets and this might change as their familiarity in the use of the device improves. The research report makes a few recommendations which include training to all students and lecturers on the effective use of tablet computers for learning and teaching and installation of relevant applications before the commencement of each academic year. Moreover, the Information and communication technology technical staff must prevent students from visiting unwanted and restricted sites by keeping a network based tracker and blocker software application.

- Description: The genome is the complete set of an organism's hereditary information that contains all the information necessary for the functioning of that organism. Complete nuclear, mitochondrial and plastid DNA constitute the three main types of genomes which play interconnected roles in an organism. Genome sequencing enables researchers to understand the regulation and expression of the various genes and the proteins they encode. It allows researchers to extract and analyse genes of interests for a variety of studies including molecular, biotechnological, bioinformatics and conservation and evolutionary studies. Genome sequencing of Rhodophyta has received little attention. To date, no published studies are focusing on both whole genome sequencing and sequencing of the organellar genomes of Rhodophyta species found in along the South African coastline. This study focused on genome sequencing, assembly and annotation mitochondrial and plastid genomes of Gelidium pristoides. Gelidium pristoides was collected from Kenton-on-Sea and was morphologically identified at Rhodes University. Its genomic DNA was extracted using the Nucleospin® Plant II kit and quantified using Qubit 2.0, Nanodrop and 1% agarose gel electrophoresis. The Ion Plus Fragment Library kit was used for the preparation of a 600 bp library, which was sequenced in two separate runs through the Ion S5 platform. The produced reads were quality-controlled through the Ion Torrent server version 5.6. and assessed using the FASTQC program. The SPAdes version 3.11.1 assembler was used to assemble the quality-controlled reads, and the resultant genome assembly was quality-assessed using the QUAST 4.1 software. The mitochondrial genome was selected from the produced Gelidium pristoides draft genome using mitochondrial genomes of other Gelidiales as search queries on the local BLAST algorithm of the BioEdit software. Contigs matching the organellar genomes were ordered according to the mitochondrial genomes of other Gelidiales using the trial version of Geneious R11.12 software. The plastid genome was also selected following the same approach but using plastid genomes of Gelidium elegans and Gelidium vagum as search queries. Gaps observed in the organellar genomes were closed by amplification of the relevant gap using polymerase chain reaction with newly designed primers and Sanger sequencing. Open reading frames for both organellar genomes were annotated using the NCBI ORF-Finder and alignments obtained from BlastN and BlastX searches from the NCBI database, while the tRNAs and rRNAs were identified using the tRNAscan-SE1.21 vi and the RNAmmer 1.2 servers. The circular physical map of the mitochondrial genome was constructed using the CGView server. Lastly, in silico analysis of cytochrome c oxidase 3 and Heat Shock Protein 70 was performed using the PRIMO and the SWISS-MODEL pipelines respectively. Their phylogenies were analysed through Clustal omega and the trees viewed on TreeView 1.6.6 software. Qubit and Nanodrop genomic DNA qualification revealed A260/A280 and A230/A260 ratios of 1.81 and 1.52 respectively. The 1% agarose gel electrophoresis further confirmed the good quality of the genomic DNA used for library preparation and sequencing. Pre-assembly quality control of reads resulted in a total of 30 792 074 high-quality reads which were assembled into a total of 94140 contigs, making up an estimated genome length of 217.06 Mb. The largest contig covered up to 13.17 kb of the draft genome, and an N50 statistic value of 3.17 kb was obtained. The G.pristoides mitochondrial genome mapped into a circular molecule of 25012 bp, with an overall GC content of 31.04% and a total of 45 genes distributed into 20 tRNA-coding, 2 rRNAcoding genes and 23 protein-coding genes, mostly adopting the modified genetic code of Rhodophyta. The SecY and rps12 genes overlapped by 41 bp. This study presents a partial plastid genome composed of 89 (38%) fully annotated genes, of which 71 are protein-coding, and 18 are distributed among 15 tRNA-coding, 2 rRNA-coding and 1 RNaseP RNA-coding genes. Sixty-one (26%) partial protein-coding genes were predicted, while approximately 84 (36%) genes are not yet predicted. In silico analysis of the cytochrome c oxidase and heat shock protein 70 showed that the gene sequences obtained in this study and the resultant transcribed protein have sequences and structures that are similar to those from several other different species, thus validating the integrity of the genome sequences. This study provides genomic data necessary for understanding the genomic constituent of G.pristoides and serve as a foundation for studies of individual genes and for resolving evolutionary relationships.

- Description: Tuberculosis is an epidemic disease which is regarded as the tenth leading cause of death in the world (World Health Organization, 2014). New 580 000 cases of multidrug resistant tuberculosis have been reported by WHO (2014). Patients diagnosed with rifampicin/multi-drug resistant tuberculosis were usually treated for 18-24 months if they convert within the designated period of 4-6 months. Several trials were conducted in other countries like Burundi, Cameroon, Central African Republic, etc. on the use of short regimen of 9-12 months. Short regimen was introduced in January 2017 in South Africa and it has not been evaluated for its effectiveness in Buffalo City Metropolitan, South Africa. This study was conducted to examine RR/MDR TB outcomes following the introduction of a short regimen and the outcomes were based on the set target of 50% MDR TB success rate and 5.4% TB client lost to follow up rate as per the Annual Performance Plan (APP) of 2017/18. The conversion rate was also examined though the target was not set in APP. A retrospective study using a descriptive design was used to collect data at Nkqubela TB and Duncan Village Day hospitals which are in Buffalo City Metropolitan. The population of the study were all records of patients diagnosed, registered and initiated on rifampicin/multi-drug resistant TB in a short regimen in Nkqubela TB Hospital and Duncan Village Day Hospital between January 2017 and July 2017. All 118 patient records that met the inclusion criteria were enrolled in the study therefore convenience sampling was used. Ethical approval was obtained from the University of Fort Hare (ethical clearance number: MUP101SSOM01). Approval to conduct the study was also approved by the Eastern Cape Department of Health Ethics, BCM Health District Manager and two public hospitals. Two research assistants and one data capture signed oath of confidentiality prior data extraction. Unique codes were used to ensure anonymity and privacy and all data was treated in a confidential manner. Data was collected using a self-designed structured questionnaire which was tested for validity and reliability through pilot study. Data analysis was done by a statistician using Statistical Packages for Social Sciences version 24. RR/MDR TB outcomes of participants who were initiated on short regimen between January and July 2017 were examined between January and July 2018 at the end of 12 months. Findings showed that the majority of the affected age group was between the ages of 36-45 years in both genders (34.7%) with males (n=71) being highly affected than females (n=47). Bisho/King William’s Town sub-district was the most affected in Buffalo City Metropolitan (n=61). The majority of participants that were affected were the Africans (98.3%), unemployed (51.7%), people living with HIV/AIDS (62.7%) and those previously treated for TB (57.6%). Records revealed that participants living with HIV had a mean CD4 count of 194.5 and 202.4 and mean viral load of 203183.0 and 651888.7. Smokers and alcohol users were higher in males (20.3% and 16.9% respectively) than in females (2.5% and 5.1% respectively). Two patient records were missing and other four patient records were incompletely recorded to determine data on smoking and alcohol consumption. Findings revealed a smear conversion rate of 68.5% excluding 47 participants who had negative baseline smear results and one participant who had extra-pulmonary TB. Twenty one percent of the participants did not have consecutive smear results during the intensive phase. TB client lost to follow up rate was 13.5% (n=16) and 10 of all TB clients lost to follow up interrupted treatment for ≥5 months. Eleven TB clients lost to follow up were from Buffalo City Municipality Metropolitan. TB client lost to follow up was high in males (n=13). Rifampicin/multidrug resistant TB treatment success rate was 72.9% with mean response to treatment of 17.2 weeks. Weight (p0.005 and CI 2.750, 15.189) and body mass index (p0.004 and CI 1.232, 6.242) as well as duration of treatment interruption (p0.000 and CI -14.785, -8. 644) and duration of treatment (p0.001 and CI -65.385, -16.403) were statistically significant to treatment success. Based on these findings, it is therefore concluded that short regimen is effective in the management of RR/MDR TB despite high TB client lost to follow up rate. Decentralisation of drug resistant TB management; primary health care reengineering; use of NIMDR-trained nurses; tracing of TB interrupters; HIV management; electronic patient management system and review of how EDR register works; proper record keeping and proper recording; extensive and ongoing counselling, patient support, health education and patient monitoring; and political involvement; is recommended. Further research is recommended to identify patient and service related factors that affect TB treatment outcomes.

- Description: Globally, poverty is a major social problem. Billions of people in developing countries, particularly sub-Saharan African countries including South Africa, continue to live in extreme poverty without access to basic needs (food, shelter, clean water and sanitation, health and education).The Eastern Cape Province has the highest number of the poor people in South Africa. The government strategies and policies to address the magnitude of poverty seem unlikely to lift the majority from poverty. Recently, however, social entrepreneurship has been recognized as the most important instrument in addressing the challenges of development (poverty, unemployment and inequality). Hence, this study was conducted to examine the role of social entrepreneurship in poverty reduction in Eastern Cape Province. A mixed research method was employed to achieve this objective. The population of the study targeted social entrepreneurs and their beneficiaries in Eastern Cape Province. The data were collected using semi-structured questionnaire from 265 social entrepreneurs and 120 social entrepreneurship beneficiaries. The participants were selected through purposive sampling technique since the population of social entrepreneurs and social entrepreneurship beneficiaries in the Eastern Cape Province is not well determined. The descriptive statistics and inferential statistics were used to analyze the data. The findings revealed that social entrepreneurship plays a crucial role in poverty reduction in Eastern Cape Province through creating employment opportunities, skill development, availability of goods and services such as financial loans. Therefore, the support for entrepreneurship culture is important for social entrepreneurship growth in order to enhance its contribution to poverty reduction. The study recommends that the government of South Africa and other vi relevant stakeholders should create conducive environment for social entrepreneurs to flourish and grow in the country to reduce poverty significantly. The growth of social entrepreneurship can lead to substantial benefits for the marginalized and vulnerable segments of the society

- 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

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: Social media is 21st century phenomenon has captured the attention of millions of people across the globe and has hitherto, permeated through all facet of our contemporary life. It has become the important conduit through which people far and near interact. Sharing of information, communicating, collaborating, engaging are some of the visible highlights of Social Media. Social media usage cut across different demographics. This is due to the unique characteristics of social media which includes openness, participation and sharing. The purpose of this study is to investigate the impact such usage have on less advantaged communities and how it can be used to further their cause in achieving socioeconomic parity. This study is qualitative in nature and it relied on semi-structured interviews and observations to collect data. Purposive and convenience sampling was used to select respondents. The findings of the study indicate that utilizing social media for the utmost gain is imperative in that the presence of new technologies has revolutionised the way people socialise beyond real time and boundaries. It was also noted that social media is the new norm as such societies far and beyond need to harness the potential not only for the social media generation but for the communities within its reach. Thus, researching into the impact this phenomenon has on the poorest communities is of great importance for both the public and policy makers. This study however recommends regulation of social media in order to contain security risks that it poses. It is therefore important to enhance internet security to protect the privacy threats. It is also important to invest more on issues of information and communication technology on low-income communities

- Description: Social protection has been introduced against the backdrop of fears that many children were not able to access their right to education. However, there have been raging debates on whether the mechanism really works to effectively support the right to education of these children. It is on the backdrop of such debates that the study was undertaken, to find out if social protection was effectively being implemented to support the right to education for vulnerable children in Mwenezi District of Zimbabwe. Given the nature of variables and research questions, the study was located within the pragmatic paradigm. A mixed-method approach and concurrent triangulation approach to closely examine the issues under study was adopted. A combination of stratified random sampling and purposive sampling approaches were used to identify the subject for the study. Data were then collected from various respondents that were considered knowledgeable about the issues under discussion. These included district level officials from Ministry of Primary Education, Ministry of Labour and Social Services, District Administrator, Chief Executive Officer as well as Civil Society Organisations. Also included as sample of the study were school heads, teachers, children and community groups. Face to face interviews, Focus Group Discussions and a survey teacher questionnaire were used to solicit the data. The study confirmed the multi-dimension nature of vulnerabilities that children in Mwenezi district were facing. Meanwhile, various social protection programmes that were seeking to address the issues of child vulnerabilities were found to be in place. Providers ranged from Government, Civil Society and private players (individuals or companies). Of significance were good practices in some communities even though these communities were not aware that they were making positive contributions to the enhancement of educational opportunities. Though, these programmes were on the ground and functional, it was their management that became the focus of much scrutiny. The programmes and their management were indeed making a contribution to enhance children’s right to education. However, there were areas that required improvement in order to raise their contribution to higher levels. The results further revealed that there was need to embrace a broader spectrum of participants, including communities and children. The institutional arrangements were also noted as requiring ii review to inject urgency and efficiency. Also recommended was the enhancement of awareness, training and networking activities by implementers, while the Government system should not involve more players but improve the systems that place children at the centre. An alternative model for social protection delivery was recommended for consideration

- 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: Lithological mapping of areas is crucial for both mineral resource identification and determination of ore concentrations. Without adequate knowledge on the extent of an area’s lithology, the above applications cannot be meaningfully accomplished. Spectroscopy-based mapping of rocks involves the use of portable reflectance spectrometers and digital maps to analyze, assess and map changes in rocks. Thereafter, understand and interpret the geochemical, physical and environmental processes that have an impact on the reflectance of the rocks while also making spatial and spectral links. Mapping lithology using remote sensing involves identification of rocks in remotely sensed images with lithological mapping being achievable through field and laboratory spectroscopy and creation of a spectral library. The main goal of this study was to measure, extract and analyze spectral signatures of dominant rocks within the Balfour Formation in order to create a spectral library that is capable of enabling, fast and cost-effective mapping of the spatial distributions of rocks within the Balfour Formation. The spectra of dominant rocks of the Balfour Formation were measured using the SR 3500 spectroradiometer. Different pre-processing techniques were applied to the acquired spectra such as smoothing, scatter correction and outlier detection. Random Forest classifier was used in the classification of the different rocks. Analysis of Variance and Bonferroni post hoc test were applied on the spectral signatures of different rocks to ascertain if there were any spectral differences between the absorption features in the spectra of the rocks. Landsat 8 imagery was used for classification of the different rocks within the Balfour Formation, maximum likelihood and spectral angle mapper were the two classifiers that were XI used. Maximum likelihood presented an accuracy of 76.19 % and 66.67 % for spectral angle mapper.

- Description: The purpose of this study was to explore students’ perceived experiences of flipped classrooms at a traditional South African university in comparison to the traditional classroom. Universities across the world are confronted with a variety of problems. One of these challenges include the massification of higher education as more students now have access to universities resulting in larger class sizes and lower through put rates. Universities have traditionally made use of the face-to-face model of lectures and tutorials as a passive mode of course instruction and delivery. However, due to the massification of higher education, it has become very difficult for lecturers to communicate and collaborate with students. One of the ways that lecturers have attempted to overcome the problem of massification is to make use of technology to increase the delivery of course content. When lectures are made available online while the traditional class time is used to build conceptual understanding and cognitive skills among students, the approach is known as ‘flipping’ the classroom. Several studies have shown that this type of active classroom approach can perform better than traditional lectures when learning outcomes are compared. There is also a very limited body of knowledge available regarding students’ perceived experiences of flipped classrooms at traditional South African universities. The theoretical frameworks guiding this study are the Activity Theory and Constructivism, whilst a pragmatic paradigm was employed. The flipped classroom was used in one course of the Management and Commerce Faculty at a traditional university in South Africa. The study was divided into three cycles: The first cycle involved 4 weeks of traditional lectures, the second cycle of 4 weeks introduced blended learning into the course, while the third cycle of 4 weeks changed the content delivery method to a flipped classroom. At the end of each cycle a formal evaluation through focus groups interviews (with 10 students per cycle) and a questionnaire (that was administered to the class) was conducted to inform the next cycle. Throughout the research process, the researcher also kept detailed field notes to as an account of the planning, execution and reflection for each class. The researcher also observed the behavior of the students during the various research cycles to provide a ‘snapshot’ of the classes. The results of the study suggest that students prefer the use of the flipped classroom is it enables them to communicate with their peers and the lecturer, and providing them with opportunities to better understand learning content through discussions and reasoning, rather than the means of receiving information. Barriers that were identified included difficulty with learning strategies and technical assistance when students needed assistance. However, students were positive about both the use of the flipped classroom as opposed to the use of the traditional classroom.

- Description: This study investigated whether there was correlation in study habits and learning styles with Mathematical Literacy among the Grade 11 (eleven) high school learners. The Amatole Education District was chosen for this study since it is composed of urban and rural schools. Since Mathematical Literacy was introduced in the system of education in South Africa with the understanding that learners who are finding it a challenge to study Mathematics be complemented with Mathematical Literacy to provide them with skills that are a prerequisite for tertiary level and participation in the economic development. The study purposed to establish whether there was a relationship between academic performance with study habits and learning styles in Mathematical Literacy. The study used the post-positivistic paradigm; the approach was quantitative and the design was descriptive correlational. In sampling probability, cluster sampling was used based on the number of high schools in the Amatole Education District of the Eastern Cape. It was then followed by sub-sampling of learners in Grade 11 (eleven) whose mathematical Literacy skills and performance were being investigated in this study. The theory of Covey on study habits and Kolb’s theory on learning styles were used as a theoretical framework for the study. The data collection instrument used was a closed-ended questionnaire based on a Likert scale measurement. Confidentiality and anonymity were emphasized with informed consent in place. Data was analyzed using SPSS software and Microsoft Excel. The results showed a significant relationship between note taking, writing skills and Mathematical Literacy skills and performance. The findings on the learning styles indicated no significant relationship between socio-demographic factors (visual language, visual numerical, auditory-numerical e.tc.) and academic performance in Mathematical Literacy. This research revealed that study habits had an impact on the academic performance of learners in mathematical literacy. This relationship between academic performance and study habits is an indication that learners needed to improve in their use of English as a second language, especially on note taking, writing skills and Mathematical Literacy.

- Description: The purpose of the study was to explore the effects of substance abuse on the academic performance and professional behaviour of students at a public nursing college in order to develop guidelines for the prevention of substance abuse. The design that was chosen as most suitable for this study was the qualitative research design. The researcher chose this method as she sought to explore the effects of substance abuse on the participants in this study. A purposive sampling method was used to select participants on the basis of their knowledge of the phenomenon.The participants who were utilised were 3rd and 4th year level students in the four year diploma in nursing. A pilot study was conducted and participants with similar characteristicsto the study population were utilised. Individual interviews were used as the means to collect data during which participants were given an opportunity to discuss issues with the intention of eliciting their views and opinions. One broad, open ended question was used to gather information from the participants and subsequent questions were used to probe further for clarity. Data were collected until saturation pointwas reached. Transcriptions were done within two days of the interview. The researcher repeatedly listened to audio recordings of the data until completely satisfied with verbatim interpretation of data. Data analysis was done manually. The researcher used the process of bracketing during data analysis and remained neutral, setting aside previous knowledge and beliefs about the phenomenon under study. The participants were allowed freedom to conduct their lives as autonomous agents, without control, coercion or exploitation. The findings revealed that: firstly, substance abuse has a negative impact of on both the academic performance and professional behaviour of the public nursing college students; secondly, that guidelines are needed for the prevention of substance abuse amongst students so as to focus on a ‘substance abuse free college environment’. vi The academic performance is negatively affected as substance abuse results in cognitive impairment, failure to meet the 85% lecture attendance requirement resulting in them repeating a year of study or being excluded from the course, and resulting in a missed opportunity to acquire scientific knowledge in nursing. The students’ academic aspirations get derailed. Students also experience strained relationships with lecturers due to drunkenness and bunking classes. Studentlecturer strained relationships are incompatible with academic achievement. Students whose professional behaviour is negatively affected by substance abuse demonstrate unethical conduct and professional misconduct in the clinical setting for experiential learning. The students fail to inculcate the values of the nursing profession and thus tarnish the image of the profession. Such students behave unprofessionally as they either absent themselves from duty, come on duty drunk or continue taking substances while on duty. They are also rude and swear at colleagues, supervisors, other staff members and patients. The students steal from colleagues and display insubordination. Their dress code is unprofessional and they are incompetent with poor standards of care towards the patients. The purpose of this study was to develop guidelines to prevent substance abuse at the college and this has been achieved. The results show that the college environment should be made substance abuse free by: firstly, identifying and mitigating the predisposing factors or reasons for substance abuse, for example: establish a proper and aesthetic infrastructure conducive to learning and teaching at the students’ residences and classrooms, set up mentorship programmes and introduce the house-mother model at residences; secondly, developing a policy on prevention of substance abuse within college premises including disciplinary measures; thirdly, developing stress management programmes for students to prevent abuse of substances as a coping mechanism, e.g. decongest the curriculum, curriculum review to be consultative, develop support groups, grant mid-year breaks and provide recreational and sporting facilities; fourthly, engage the services of a vii professional therapist for students who are already abusing substances or referral to the therapist; fifthly, clinical accompaniment should be strengthened for effective correlation of theory and practice; and, lastly, engage the services of a financial advisor to give guidance on income and expenditure with regard to student stipend instead of spending it on substances.

They are also rude and swear at colleagues, supervisors, other staff members and patients. The students steal from colleagues and display insubordination. Their dress code is unprofessional and they are incompetent with poor standards of care towards the patients. The purpose of this study was to develop guidelines to prevent substance abuse at the college and this has been achieved. The results show that the college environment should be made substance abuse free by: firstly, identifying and mitigating the predisposing factors or reasons for substance abuse, for example: establish a proper and aesthetic infrastructure conducive to learning and teaching at the students’ residences and classrooms, set up mentorship programmes and introduce the house-mother model at residences; secondly, developing a policy on prevention of substance abuse within college premises including disciplinary measures; thirdly, developing stress management programmes for students to prevent abuse of substances as a coping mechanism, e.g. decongest the curriculum, curriculum review to be consultative, develop support groups, grant mid-year breaks and provide recreational and sporting facilities; fourthly, engage the services of a vii professional therapist for students who are already abusing substances or referral to the therapist; fifthly, clinical accompaniment should be strengthened for effective correlation of theory and practice; and, lastly, engage the services of a financial advisor to give guidance on income and expenditure with regard to student stipend instead of spending it on substances.

- Description: The economic crisis in Zimbabwe has resulted in poor working conditions, low remuneration and lack of resources. This situation has led to low morale of qualified teachers. The supervision of student teachers therefore, represents extra work for the teachers, who are already over-burdened by large classes and the demands associated with the introduction of new subjects from time to time. Some mentors feel that they need to be given incentives for their role in the training of teachers. Furthermore, research suggests that some student teachers are struggling with their teaching practice which is an important aspect of their teacher education. It is for this reason that the researcher sought to conduct a case study that would examine the supervision of student teachers by school based supervisors in Zimbabwean primary schools. Purposive sampling was used to select eighteen student teachers and nine supervisors. This study, which is qualitative in nature, was grounded in the constructivist paradigm. Semi-structured interviews were deployed to gather data and Focus Group Discussions and document analysis were also used for triangulation purposes. The data revealed that although student teachers were supervised by their mentors, there were divergent perspectives with regard to how supervision of student teachers should be conducted, with a significant number understanding supervision as checking and controlling of student teachers‟ work. It also emerged from the data that good relationship with mentors was beneficial to student teachers. However, the majority of student teachers reported serious challenges that included lack of orientation mentors and inadequate supervision due to busy schedule of their mentors. Based on the findings of the study, the study recommends that School ~ viii ~ Heads should choose well-qualified and experienced teachers to mentor and supervise student teachers so that they serve as good role models to the students, and that clear supervision guidelines be developed to achieve uniformity in the supervision of student teachers.
