- Description: Grassland degradation associated with climate change and inappropriate grassland management has been characterized as a global environmental concern driving decreased grassland ecosystem's ecological functioning. More than 60% of South African grassland is degraded or permanently transformed to other land uses and nearly 2% properly conserved. Yet, grasslands are a major source of food for livestock grazing and provide material and non-material benefits to many livelihoods. Therefore, grassland above-ground biomass (AGB) estimation is crucial in planning and managing pastoral agriculture and the benefits derived from it. However, current grassland monitoring techniques used in rural smallholder livestock farms rely on conventional methods, which are destructive, labour-intensive, costly, and restricted to small areas. This study investigated the monitoring and modelling of protected grasslands biomass using current Earth observation systems (EOS), an approach, which is non-destructive, cost-effective, cover larger areas and is a time-saving alternative to conventional methods. Hence, the research objectives were: (i) to map the trends and advances in data and models used in the monitoring of grassland (pastures) with Earth observation systems, and (ii) to assess above-ground biomass estimation in semi-arid savannah grassland integrating Sentinel-1 and Sentinel-2 data with Machine-Learning. This goal was to assess if this approach could provide the requisite information, which could contribute to the long-term goal of developing a semi-automated system for data processing, and mapping grassland biomass to benefit local communities. For this investigation, it was crucial to understanding what research had achieved so far in this area of pasture management. An assessment of the Scopus database showed the recent developments in European Union (EU) programs and Sentinel missions, including statistical models and machine learning for monitoring grassland changes at multiple scales. However, Sentinel-1 and Sentinel-2 data, machine learning models, and variable importance techniques were applied for grassland AGB estimation. These techniques have been used in similar studies to determine optimum machine learning models, influential variables, and the capability of integrated Sentinel datasets for mapping grassland AGB, spatial distribution, and abundance. Results showed improved performance with the Random forest regression (RFR) model (R² of 34.7%, RMSE of 9.47 Mg and MAE of 7.68 Mg ). The study also observed optimum sensitivity of Difference Vegetation Index (DVI) and Enhanced Vegetation Index (EVI) in all three machine learning models for modelling grassland AGB estimation in the study area. A further, statistical comparison of all three machine learning models showed an insignificant difference in the predictive capacity for AGB in the study area with Gradient Boosting regression (GBR) model (R² of 27.7, RMSE of 9.97 Mg and MAE of 8.03 Mg ) and Extreme Gradient Boost Regression (XGBR) model (R² of 17.3%, RMSE of 10.66 Mg and MAE of 8.83 Mg ). The study revealed that an integration of Sentinel-1 and Sentinel-2 has improved capabilities for monitoring grassland AGB estimation. This research sheds light on the timely and cost-effective techniques for grassland management strategies to enhance or restore the ecological functioning of grassland ecosystems and promote community sustainability. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

- Description: The study seeks to explore the use of electronic information resource in the University of Fort Hare (UFH) Library. The objectives of the study are to determine factors that influence acquisitions of electronic information resources at UFH library, to find out the user’s responses to electronic information resources in the library and identify the challenges faced by UFH library regarding the usage of electronic information resources. The literature review was conducted through an acquisition of electronic information resources in academic libraries, collection development policies of academic libraries in South Africa and application of electronic information resources within South Africa and globally. The study is based on Diffusion of innovation (DOI) theory. The study adopted qualitative and quantitative approaches, and the non-probability sampling-Quota sampling was used for students and purposive sampling technique for librarians and academics. The data was collected with self-administered questionnaires and document analysis. The study found that academics were not fully involved in the acquisition of the library electronic information resources; therefore, there is a lack of communication about the acquisition of electronic resources. The study further reveals that there is usage of electronic information resources; however, there are library users who prefers to use search engines such as google, yahoo etc. It was also identified that there are two important barriers that hinder the use of electronic information resources, i.e. physical and personal barriers. The study recommends that University of Fort Hare library should consider including e resources in the collection development policy. It is also recommended that the library online training/tutorials must be installed on the library website to increase the usage of e-resources. In order to stay relevant and visible, librarians should embrace new opportunities and go beyond the comfort zone of traditional librarian principles.

- Description: The present study investigates the use of English and isiXhosa in teaching and learning Physical Sciences in four King Williams Town schools. Physical Sciences educators and Grade 11 Physical Sciences learners were interviewed to find out about their perceptions with regard to the language(s) used in the learning and teaching of the subject Physical Sciences. The same educators and learners were also observed to find out their actual language practices in class. The findings revealed that English was the preferred medium of instruction in the learning and teaching of Physical Sciences, even though the majority of learners had low proficiency in English. Both teachers and learners extensively use code-switching to bridge this language gap in order to improve the learning of content. The choice to use isiXhosa to bridge the English second language barrier was influenced by the language profile of the learners. However, even in lessons in which teachers used code-switching, the participation of learners in class discussions was very low because the delivery of the lessons was still teacher-centred. The National Department of Education assessment policy seems to limit schools toward adopting English as the LoLT even though learners in these schools were isiXhosa first language speakers. The fact that all assessment are done in English leads to school adopting English on LoLT. Schools adopted the English only policy as way of promoting learners’ learning and understanding of English, so that the learners are not disadvantaged by the English language factor when writing examinations.

- Description: Proper and timeous communication amongst different social development participants is one of the main driving factors for successful human progress. Different platforms have been used by different industries across the globe to ensure that useful information is shared with relevant structures at appropriate times. The global increase on use and availability of Information Communication Technologies (ICT’s) has prompted a thorough analysis and study of their relevance on different industries. Much of the increase has been observed mainly on highly urbanized areas, where the majority of the population is literate and who are above the poverty line. Some researchers have argued that the language used in some of the ICT’s is limited to the elite few, while others highlight cost implications in the use of these ICTs. The agricultural industry is not immune to the debates that relate to the development of ICTs, it is in most cases at the center, due to its diverse nature (in terms of participation) and close linkage to human development. There seems to be a correlation between ICT usage and the economies of scale in agricultural development, where smallholder farmers tend to use less of highly modernized ICTs, while commercial large scale farmers use more of the modernized ICTs. This disparity amongst farmers is exacerbated in many areas by the differing support systems employed by the public extension services. This study was initiated in order to study the usage and relevance of the ICTs by the smallholder farmers of the Umzimvubu Local Municipality of the Eastern Cape Province in South Africa. The research address the following research questions: 1. Which ICTs are owned by smallholder farmers of Umzimvubu local municipality? 2. Do smallholder farmers use ICTs to communicate agricultural information? 3. What are the types of ICT devices and services used by smallholder farmers for vi agricultural development? 4. What are the challenges faced by smallholder farmers when using ICTs to communicate agricultural information? A survey questionnaire was then developed to collect the relevant data from randomly selected six villages of Umzimvubu Local Municipality. The questionnaires structure employed both closed and open-ended questions that were administered using a face to face interview, conducted on the sample population in each village. The results indicated that the most common ICTs that were owned by smallholder farmers in the study area were: mobile phones (33%), televisions (TV) (28%), and radio (20%). The results also showed that communication amongst farmers (35%) and extension officers (35%) was the most notable use of mobile phone from the study area. The results also revealed that most smallholder farmers faced the following challenges when using ICTs to retrieve agricultural information; poor signal (40%), inconsistent broadcasting times for TV and radio agricultural programmes (35%), language barrier (15%) and lack of electricity (10%). The study, therefore, concludes that a majority of smallholder farmers from the study area own ICT devices necessary for rural agricultural development (mobile phones, TV and radio) that can be targeted by extension officers, policy makers, rural development implementing agencies and agro-industries to promote rural development. However, several challenges (language barrier, poor network signal and no electricity) limit the potential of these ICT devices and services from fully benefiting smallholder farmers.

- Description: The study investigated the use of Internet-based information sources by postgraduate students at three universities in the Eastern Cape province of South Africa. The main aim of the study was to determine the factors that affect the use of Internet-based information sources by postgraduate students. The study sought to fulfil the following objectives: to determine factors which affect the use of Internet-based information sources by postgraduate students at the three universities in the Eastern Cape, South Africa; to establish the Internet-based information sources available among universities in Eastern Cape; to identify the pattern of postgraduate students’ use of Internet-based information sources; to find out the level of postgraduate satisfaction with Internet-based information sources available for their information needs, and to suggest ways of stimulating the use of Internet-based information sources by postgraduate students at universities in the Eastern Cape, South Africa. A review of the literature revealed a growing reliance on electronic resources by higher education institutions worldwide to suffice the information needs of academic researchers and that usage of these is influenced by various factors. The factors identified in the reviewed literature as affecting the use of Internet-based information sources among students include: academic discipline affiliation, age, level of study, gender, information and communications technology (ICT) literacy, institutional support, relevance of available information resources, accessibility, marketing and publicity of information sources available, and training. The researcher employed a survey research methodology to achieve the study objectives, through data collection on three fronts. Firstly to investigate the factors hat affect the use of Internet-based information sources from the perspectives of postgraduate students, self-administered questionnaires were distributed to a sample of 200 study participants obtained using quota sampling of the population of students from the three universities. A response rate of 66.5% was achieved. Secondly, data on the organisational factors influencing the use of Internet-based information sources were obtained by conducting semi-structured interviews with selected librarians at the three universities. Lastly, documentary analysis was also used to corroborate data obtained from the survey with postgraduate study participants, as well as from interviews with selected librarians. The findings include that the use of Internet-based information sources is increasingly becoming important for postgraduate students at the selected universities in the Eastern Cape, South Africa. Postgraduate students believe that Internet-based information sources are useful in their academic work. There was moderate use of subscription e-databases and e-journals. Level of study and age were found to affect the use of Internet-based information sources, with older, Masters and PhD students utilising e-databases and e-journals more frequently. Postgraduate students predominantly use search engines to gain access to Internet-based information sources, while Online Public Access Catalogues (OPACs) and library websites were unpopular gateways to Internet-based information sources. Universities in the Eastern Cape were found to be supportive of the use of Internet-based information sources with budgets of libraries and future plans tipped in favour of electronic resource provision. From the findings of the study the key recommendations suggested for improving the use of Internet-based information sources by postgraduate students in the Eastern Cape province of South Africa, include that Information literacy training programmes at the three universities may be tailor-made to cater for the information needs of postgraduate students at varying levels and academic disciplines of study. It was also recommended that the universities incorporate the use of federated searching and searchable journals management software on their library websites, in order to increase the visibility of Internet-based information sources among postgraduate students.

- Description: The study sought to investigate the use of RFID technology as inventory control in academic libraries in South Africa, with a focus on the University of South Africa and the University of Fort Hare libraries. The objectives of the study were to describe the current inventory control practices at the libraries of the University of South Africa and the University of Fort Hare in order to determine the infrastructure required for the use of RFID for inventory control for the University of Fort Hare’s libraries; to evaluate the benefits of RFID technologies, in order to gain a competitive advantage for the University of South Africa’s and the University of Fort Hare’s libraries; to identify the challenges associated with adopting RFID technology, as experienced by the libraries of the University of South Africa and the University of Fort Hare. The study adopted both the quantitative and qualitative research approaches. The researcher followed a rigorous methodological path that began with a thorough literature review coupled with the careful and thoughtful posing of research questions and objectives. A purposive sample of forty (40) respondents was selected from the library staff from both the University of South Africa and University of Fort Harelibraries. The collected data were analysed using the Statistical Package for Social Sciences 23 (SPSS 23) and Microsoft Excel 2010. The findings of the study revealed reasons for both academic libraries to invest in RFID technology; these reasons include RFID’s ability to deliver self-service options, inventory control, improved reader access and improved security. The challenges related to the implementation of RFID technology are also related to staff not being rewarded by library management for being innovative; the difficulty of staff learning new technology; the staff’s inability to generate new ideas for the library; and the staff not being able to share knowledge with each other. Further research needs to be conducted by library RFID vendors in order to meet the need, of academic libraries, for RFID inventory control. RFID hardware and software (API software) should be subjected to further investigation for the purposes of research and development. Libraries should work closer with RFID vendors so as to trial and test hardware and software.

- Description: The study sought to investigate the use of RFID technology as inventory control in academic libraries in South Africa, with a focus on the University of South Africa and the University of Fort Hare libraries. The objectives of the study were to describe the current inventory control practices at the libraries of the University of South Africa and the University of Fort Hare in order to determine the infrastructure required for the use of RFID for inventory control for the University of Fort Hare’s libraries; to evaluate the benefits of RFID technologies, in order to gain a competitive advantage for the University of South Africa’s and the University of Fort Hare’s libraries; to identify the challenges associated with adopting RFID technology, as experienced by the libraries of the University of South Africa and the University of Fort Hare. The study adopted both the quantitative and qualitative research approaches. The researcher followed a rigorous methodological path that began with a thorough literature review coupled with the careful and thoughtful posing of research questions and objectives. A purposive sample of forty (40) respondents was selected from the library staff from both the University of South Africa and University of Fort Harelibraries. The collected data were analysed using the Statistical Package for Social Sciences 23 (SPSS 23) and Microsoft Excel 2010. The findings of the study revealed reasons for both academic libraries to invest in RFID technology; these reasons include RFID’s ability to deliver self-service options, inventory control, improved reader access and improved security. The challenges related to the implementation of RFID technology are also related to staff not being rewarded by library management for being innovative; the difficulty of staff learning new technology; the staff’s inability to generate new ideas for the library; and the staff not being able to share knowledge with each other. Further research needs to be conducted by library RFID vendors in order to meet the need, of academic libraries, for RFID inventory control. RFID hardware and software (API software) should be subjected to further investigation for the purposes of research and development. Libraries should work closer with RFID vendors so as to trial and test hardware and software.

- Description: Mathematics is the foundation for the economic and technological development of any nation. It has been asserted that Mathematics is expected to help in accelerating social, economic and technological progress of any society. The Primary school level is very important in any educational system and any lack at this level would permeate to other levels of the educational system. Hence, this dissertation examines the use of textbooks by teachers in teaching Mathematics at selected primary schools in East London Education district. The study adopted the interpretivist paradigm and employed the qualitative approach in investigating the phenomenon. The dissertation made use of phenomenology research design as it attempted to understand people’s (learners’ and teachers’) perceptions, perspectives and understandings of the use of textbooks in teaching Mathematics. Semi-structured interviews and observation were used to elicit information from the six mathematics teachers and three heads of department who were purposively selected. The data collected were analysed using thematic approach where themes were developed from the research questions after transcribing, sorting and categorizing them. The findings of the study demonstrated that the participants selected textbooks from the ones prescribed by the department that were written in the CAPS documents. They had no influence or decision on textbook selection. All the teachers believed that lesson plan is very important and it is a must to have a very detailed and comprehensive lesson plan that is well-aligned to the contents of CAPS document and the textbook. The study further revealed that, for effective delivery of lesson and planning, there is need for a practical use of textbooks by the teacher. The study concluded that one of the most fundamental issues to consider is the fact that, as good as the use of textbook for planning and delivery of lesson activities is, it can also be a problem if not carefully and professionally planned and used accordingly. The over-dependence on textbooks at the expense of other resources may cause ineffective learning and teaching of mathematics.

- Description: In the recent years have been several public protests in our communities which was a result of slow pace in the provision of services by the municipalities in the district which has led to the use of the performance management system in order to accelerate the service delivery. The study focused on the usage of the system like performance management to accelerate service delivery in Amatole District Municipality (ADM) in the Eastern Cape Province. There is limited research regarding the usage of the system like performance management to accelerate service delivery in Amatole District Municipality. Mixed research methodology was used. The sample (n=10) comprised of individual involved in performance management systems. Data was collected through the questionnaire method and both qualitative and quantitative methods were used for data analysis. The study results show that while the performance management systems are being practiced at the municipality it is not done effectively and efficiently. In addition, not all municipal employees had the necessary knowledge and expertise to implement PMS. It can also be noted that every respondent in the study agreed that performance management systems do accelerate service delivery if done efficiently. The study recommends that local government should not only focus on their plans on dealing with backlogs but also on the rapid development taking place and the performance management system framework should cater for individual performance.

- Description: Introduction Contraception has been identified as one way in which women can prevent unwanted pregnancies. Contraceptive utilization has been proved to minimize maternal mortality by lowering the risk of pregnancy and its associated life-threatening problems. Therefore, the researcher conducted a study at Stutterheim about the “utilization of contraceptives amongst adolescents at Stutterheim in Eastern Cape Province” with the intentions to explore perceptions of adolescents on utilization of contraceptives and to determine the factors that influence that contraceptive utilization. Methods This study adopted a quantitative, descriptive cross-sectional design which involved questionnaire tools completed by 436 adolescents between the ages of 14 and 19 years at Stutterheim health facilities and the surrounding schools, regardless of whether they were sexually active or not. After obtaining ethical clearance from the University ethics Committee and permission from the Department of Health the researcher visited the gatekeepers for obtaining informed consent and data collection procedures. The researcher administered the instruments herself to ensure validity and reliability of the instrument through a pilot study. The respondents of the pilot study did not participate in the major study. Any irregularities with the data instruments were corrected accordingly. Data collection took 3 weeks to complete all the sites. The raw data was captured onto an Excel spread sheet and analysed by the researcher with the assistance of a statistician. Results The data suggests that as much as the parents discuss about sex related issues and pregnancy, they are less likely to educate their adolescent girls about contraceptives probably due to the beliefs they have, lack of knowledge and the fear of introducing them into premarital sex. The 34.4percent of participants indicated that they were scared of contraceptive rumours spreading around the community as well as the stigmatization. Conclusion Due to the results of this study the Department of Health should work together with the department of education to put into effect the optimal utilization of contraceptives amongst adolescents by adding sexual, reproductive and contraceptives health education, as a subject in the school curriculum. Department of health must also make use of main media and social media since they are influential and can be the great sources of information for campaigns and more seminars on contraceptive utilization and its benefits to the adolescents, society and the State. , Thesis (MPH) -- Faculty of Health Science, 2022

- Description: Within the first decade of the ICC‟s existence, its case docket was composed of cases originating from Africa only. Relations between the African governments represented by the AU quickly deteriorated. The AU accuses the ICC of bias and unfair targeting of Africa. After the indictment of heads of states that include Omar Al Bashir of Sudan, Uhuru Kenyatta of Kenya and the late Muammar Gaddafi of Libya, the AU passed several resolutions where it reiterated its commitment to the rule of law and to combating impunity. The AU, however, instructed member states to cease all cooperation with the ICC. African states that are ICC members are now faced with conflicting obligations as a result of the AU resolutions. Moreover, the AU resolutions raise the spectre of a legitimacy crisis for the AU and a conflict between articles 27(2) and 98(1) of the Rome Statute. Based mostly on desk research coupled with my experience working on human rights and access to justice programmes in Sudan, South Sudan, Somaliland, Ethiopia, Kenya, Uganda and Zimbabwe, this thesis considers the possibility that the ICC is suffering from a legitimacy crisis as a result of the fall out and the issues of unfair selectivity that are raised by the AU. Employing the Third World Approaches to International Law as an analytical framework, the study attempts to reconcile the apparent contradictions in the new outlook and rhetoric of the AU pursuant to its Constitutive Act and the instruction to member states to withdraw cooperation with the ICC. The thesis also proposes practical ways to resolve the conflicting obligations caused by the AU resolutions and by operation of customary international law immunity of high ranking state officials referred to the ICC by way of a Security Council resolution. The current situation gives the ICC the appearance of a weak institution that is only good for low hanging fruit, which has a negative effect on the legitimacy of the ICC.

- Description: The World Trade Organisation Agreement on Technical Barriers to Trade (TBT Agreement) was crafted with the aim of ensuring that technical regulations, standards and conformity assessment procedure do not constitute unnecessary obstacles to international trade. Southern African Development Community (SADC) countries have since ratified this Agreement and took a step further to incorporate its principles into the Technical Barriers to Trade Annex to the SADC Protocol on Trade. Despite this effort, SADC countries are still grappling with implementing the TBT Agreement in their domestic frameworks. Consequently, technical barriers to trade have become impediments to both regional and international trade. It is in this context that this study aims to examine the implementation of the TBT Agreement within the SADC. The study answers the question what are the challenges facing SADC Member states to fully implement the TBT Agreement? The study demonstrates that SADC Member face challenges which include of lack adequate resources, technical expertise and enforcement mechanisms to effectively implement the TBT Agreement. In the finality, the study recommends SADC Member states to deepen regional integration in order to collaborate on matters relating to technical barriers to trade within the region. Member states should also share information and learn from the experiences of other countries on how to effectively implement the TBT Agreement. Further, government officials should be educated on trade-friendly regulations that do not compromise on the principles of the TBT Agreement. To this end, regulatory impact assessments should be established in order to assess the trade effects of both new and old regulations. Effective enforcement mechanisms should also be introduced in order to coerce Member states to comply with their regional obligations. By effecting these recommendations, SADC states have the opportunity to eradicate technical barriers to trade thereby increasing both regional and international trade.

- Description: This study analyses a selected cohort of black South African novelists‟ depiction of the real burning issues of the post-Apartheid South Africa. The ideas that the study is concerned with in the novel under study, are based on the aspect of theme and how it is utilised by the respective authors to address the social, economic and political issues in the post-Apartheid South Africa. The study is an investigation of the extent to which black South African novelists have depicted the aforementioned issues. The research highlights those issues that the novels under study addressed and continues by revealing how the authors depict these issues in their texts. Moreover, the study concludes that literature has a role to play in the society and recommends that it should be reliable and useful to the society. It further recommends that literature should not ignore societal issues and should be corrective in its approach. The study is comprised of six chapters: Chapter One functions as an introduction to the study. It provides information on the aims and objectives of the study, the background information on the novels under study and South African literature itself. The chapter also outlines the method and the theories, which will be used in the study. It concludes by addressing the significance of the study. Chapter Two provides a detailed analysis of the theories, which will be used in the study. This includes the Marxism and Realism theory, Afrocentric theory and the Feminist Literary theory. It also defines the concept of theme and outlines its characteristics. It discusses post-colonial literature and its development in Africa. The chapter will conclude with a disclosure of the role of theme and of the author in the African novel. Chapter Three addresses the depiction of burning issues in Mpe‟s novel “Welcome to Our Hillbrow”. It discusses the real post-colonial challenges confronting the society during the post-Apartheid South Africa. It determines whether the novel under study adequately addresses these issues. Chapter Four identifies and addresses the depiction of burning post-colonial issues in Magona‟s novel “Beauty‟s Gift”. It unveils the themes that are dealt with in the novel under study thereby linking them effectively to the current situation in the new South Africa. Chapter Five unveils the central themes in Mahala‟s Novel “When a Man Cries” and it illustrates how the author protests against the ills of post-Apartheid South Africa. Chapter Six serves as the conclusion of the study and brings out the findings and recommendations of the study. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: The difficulty that exists in accurately monitoring the performance of air conditioners has made performance prediction an arduous task. Nevertheless, the performance still needs to be monitored and predicted as it helps solve a lot of problems resulting from this technology like effect of the technology on the grid, energy consumption, water utilisation and GHGs emission. With the introduction of regression modelling as a means of system monitoring and prediction some years ago, the accuracy was still a call for concern. It is worth realising that increasing the number of predictors will enhance this method’s accuracy. As such, this document intends to increase the accuracy of this method’s monitoring and predicting ability by increasing the number of predictors to cut across system thermal, environmental and human behavioural variation. These predictors experimentally gotten are used to build an environ-behavioural model that monitors the coefficient of performance and energy consumption of a domestic split-type air conditioner with higher accuracy. Refrigerants have undergone evolution in the past decades in a bid to come up with a refrigerant that has zero ODP, lower – than – R22 GWP and much better than R22 thermodynamic performance. No pure refrigerant has been found to possess these qualities as such mixtures or blends are the best shot at the moment. R410A could stand the test of time to be the long term R22 replacement but for the fact that besides R410A’s higher GWP than that of R22, the former’s system performance is lower than that of the latter’s due to the lower thermodynamic performance of the former. This means the search continues. In this document, a combination of carefully chosen refrigerant components are carefully blended to come up with a simulation based R22 long term replacement, which will be referred to in this document as BTEP.
