Thesis (M.A. Agricultural Management (Agricultural Extension)) -- University of Limpopo, 2019 / The aim of the study was to investigate the perceptions of AEPs towards ICT tools to understand why AEPs are not using the ICT tools for their work as expected by the department of agriculture. The data was collected from AEPs by means of selfadministered, semi-structured questionnaire in the Tshebela and Mankweng service centres of Polokwane Local Agricultural Office. The findings firstly, indicate that less than half of the respondents are unaware of the advantages of the ICT tools for their work. This means more than half of the respondents are aware of the advantages of using ICT tools for their extension work. Secondly, the results show that less than half of respondents are aware of the disadvantage of the ICT tools for their extension work. This also implies that more than half of the respondents are not aware of any disadvantages of the tools for their extension work. Furthermore, with regard to the research question about the prominence of four ICT tools used together, the findings indicate that respondents believe that the combined use of four ICT tools (laptop, smart phone, smart pen technology and ESO) is helping them to achieve their extension career goals compared with the use of smart phone and laptop only. The hypothesis test of the influence of selected variables on the number of ICT tools used by AEPs show that the socio-economic characteristics of AEPs such as age, lower income, lack of training in the use of laptop (compatibility), and relative advantages issues such as awareness of disadvantages of the ICT tools have a negative influence on the number of ICT tools used as expected. The test also shows that the other variables such as sex, education, ESO training, SPT training, Smartphone training, unawareness of advantages and prominence positively correlate with the dependent variable. These positive relationships notwithstanding, the test indicates that only training received in the use of smart phone makes a significant contribution to the number of ICT tools used by AEPs. There is evidence from the study findings to suggest that most AEPs are aware of the advantages compared with the disadvantages of ICT tools for their extension work. Furthermore, the positive views expressed by AEPs about the prominence of the use of the four ICT tools together in helping them to achieve their extension career goals over the use of two tools shows that AEPs are motivated to use these four tools together. The department of agriculture should invest more in training AEPs in the use of the four ICT tools because they influence their use. AEPs however, highlighted challenges which hinder their use of the four ICT tools together and which need to be addressed by the department of agriculture to ensure that the four tools are used together. These include access to internet, non-supply of some of the tools by the employer, non-replacement of damaged ICT tools, inconvenient reimbursement structure which requires AEPs to use their own money upfront to purchase data bundle. Keywords: Information Communication Technology, Agricultural Extension Practitioners, awareness of disadvantages, unawareness of advantages, prominence.

Thesis (M. A.) --University of Limpopo, 2021 / This is an exploratory study conducted to assess the effectiveness of the digital migration in South Africa. This study focused on two areas of domicile, which embarked on the process of migrating in Limpopo Province i.e. Shayandima Village in Thohoyandou and Rapotokwane Village in Bela-Bela. The theories that were used to guide the study were the diffusion of innovations theory, political economic theory and media policy theory. These theories were employed to assist in assessing the process, the effectiveness and the importance of Digital Migration. The results for this study are revealed that 85% of respondents asserted that digital broadcasting is very effective and easy to use compared to the analog broadcasting systems, as it shows clear pictures, quality sound and access to more television channels. This help television viewers to get quality television programs. It was interesting to note that respondents mentioned that they did not regret migrating from analog to digital broadcasting because of the benefits and impact that the Set Top Boxes Set (STB)s have on their televisions. The findings reveal that the STBs are effective and affordable and enable to watch more television channels. There is also a need for the Department of Communication and Digital Technologies to ensure that every household in South Africa migrates to digital broadcasting system

Thesis (M.Ed. (Language Education)) -- University of Limpopo, 2022 / The primary aim of the study was to investigate ways in which learning and teaching of English First Additional Language writing skills can be taught through Information and Communication Technology. Four teachers from School A were interviewed and Four teachers from School B were observed. Six learners typed letters from School A, and six wrote essays from School B. The results indicated that learners and teachers from School A had more knowledge in incorporating Information and Communication Technology(ICT) into teaching and learning writing skills, and that also improved their performance. School B, due to lack of ICT skills in EFAL writing skill, resulted in learners committing errors and indicating a distress to teachers in their learning and teaching of EFAL writing skills. Nonetheless, the recommendations were clearly stated that teachers should be given sufficient training, especially from School B, regarding the application of ICT through teaching English writing skills. It should be every teacher, learner, and parent’s responsibility to monitor and assist their learners through ICT learning. Lastly, relevant policies should be drafted to make ICT compulsory in learning and teaching language, together with provision of resources to support this new norm of learning and teaching.

This investigation is concerned with the problem of Texas employers' inability to hire adequately trained technical communication personnel because Texas universities and colleges do not offer a bachelor's degree program for that career field. This study contains the results of five separate surveys that investigate the backgrounds and training of present technical communication personnel and the training desired by supervisory personnel. The study also recommends a bachelor's degree program in technical communication with three technological specialties: electronics, mechanical, and chemical/petroleum. Anticipated problems in setting up such a degree program and possible solutions to the problems are discussed in the study. The suggested freshman and sophomore curriculum could be used as a guideline for a junior college associate program.

This dissertation deals with some crucial building blocks of cryptosystems in symmetric cryptography / namely the Boolean functions that produce a single-bit result for each possible value of the m-bit input vector, where m&gt / 1. Objectives in this study are two-fold / the first objective is to develop relations between cryptographic properties of Boolean functions, and the second one is to form new concepts that associate coding theory with cryptology. For the first objective, we concentrate on the cryptographic properties of Boolean functions such as balancedness, correlation immunity, nonlinearity, resiliency and propagation characteristics / many of which are depending on the Walsh spectrum that gives components of the Boolean function along the direction of linear functions. Another efficient tool to study Boolean functions is the subject of covering sequences introduced by Carlet and Tarannikov in 2000. Covering sequences are defined in terms of the derivatives of the Boolean function. Carlet and Tarannikov relate the correlation immunity and balancedness properties of the Boolean function to its covering sequences. We find further relations between the covering sequence and the Walsh spectrum, and present two theorems for the calculation of covering sequences associated with each null frequency of the Walsh spectrum. As for the second objective of this thesis, we have studied linear codes over the rings Z4 and Z8 and their binary images in the Galois field GF(2). We have investigated the best-known examples of nonlinear binary error-correcting codes such as Kerdock, Preperata and Nordstrom-Robinson, which are -linear codes. We have then reviewed Tokareva&rsquo / s studies on Z4-linear codes and extended them to Z8-linear codes. We have defined a new classes of bent functions. Next, we have shown that the newly defined classes of bent, namely Tokareva&rsquo / s k-bent and our t,k-bent functions are affine equivalent to the well-known Maiorana McFarland class of bent functions. As a cryptological application, we have described the method of cubic cryptanalysis, as a generalization of the linear cryptanalysis given by Matsui in 1993. We conjecture that the newly introduced t,k-bent functions are also strong against cubic cryptanalysis, because they are as far as possible to t,k-bent functions.
