Clustering is the process in which data is differentiated, classified according to some criteria. As a result of partitioning process, data is grouped into clusters for specific purpose. In a social network, clustering of people is one of the most popular problems. Therefore, we mainly concentrated on finding an efficient algorithm for this problem. In our study, data is made up of two types of entities (e.g., people, groups vs. political issues, religious beliefs) and distinct from most previous works, signed weighted bipartite graphs are used to model relations among them. For the partitioning criterion, we use the strength of the opinions between the entities. Our main intention is to partition the data into k-clusters so that entities within clusters represent strong relationship. One such example from a political domain is the opinion of people on issues. Using the signed weights on the edges, these bipartite graphs can be partitioned into two or more clusters. In political domain, a cluster represents strong relationship among a group of people and a group of issues. After partitioning, each cluster in the result set contains like-minded people and advocated issues. Our work introduces a general mechanism for k-way partitioning of signed bipartite graphs. One of the great advantages of our thesis is that it does not require any preliminary information about the structure of the input dataset. The idea has been illustrated on real and randomly generated data and promising results have been shown.

The primary purpose of this study is to develop a methodology that can be used to assess IS effectiveness in the Turkish Army. This study starts with the review of the information system effectiveness and assessment paradigms. Afterwards, influences of the characteristics of the Turkish Army on IS effectiveness assessment techniques are investigated. Observations and interviews are determined as the favorable data collection techniques. A user perceived effectiveness assessment instrument for semi-structured interviews is developed. Then a case study is applied to assess IS effectiveness in one of the units of the Turkish Army. At the end of the thesis, a qualitative assessment methodology based on maturity and key determinants of a successful IS are proposed for the Turkish Army.

L’étude des usages et pratiques informationnels des usagers en démarche de recherche d’information est un axe majeur de la recherche en sciences de l’information et de la communication, à en juger par les travaux consacrés à cette problématique et disponibles sur Internet. Si les pays du Nord ont une tradition bien ancrée en la matière, au Sud, par contre, et plus précisément dans les pays francophones d’Afrique au sud du Sahara, peu d’études ont été consacrées à cette thématique. Au Mali, les références de travaux de thèses sur ce sujet sont quasi-inexistantes.La présente étude se place dans ce contexte thématique et géographique, et vise comme public cible les doctorants de l’Université de Bamako. Il s’agira d’abord de définir une typologie de cette communauté d’utilisateurs de l’information (spécialisation, écoles doctorales et laboratoires d’attache, thématique de recherche, etc.), puis d’évaluer ses besoins et pratiques informationnels et enfin d’identifier l’existence de difficultés éventuelles d’accès à l’information et de proposer des pistes de solutions. Pour la collecte de données une enquête réalisée auprès de doctorants et l’observation de leurs comportements en situation de recherche d’information seront privilégiées. Les résultats de l’étude permettront une meilleure connaissance des besoins et pratiques informationnels de la communauté des doctorants de l’université de Bamako et pourraient être utilisés par les unités d’information en vue d’améliorer l’offre de services d’information à leur intention. / The study uses and informational practices of users in information retrieval process is a major focus of research in Information and Communication Sciences, judging by the work on this issue and on the Internet. If the North has a strong tradition in this area, to the south by cons, specifically in Francophone countries of Africa in south of the Sahara, few studies have been devoted to this theme.In Mali, the thesis work of reference on this subject is almost non-existent.This study falls within this thematic and geographical context and aims as public target doctoral students from the University of Bamako. This will be first to define a typology of this information users community (specialization, doctoral schools and laboratories attachment, thematic research, etc.) and then evaluate its information needs and practices finally, to identify the existence of possible access to information problems and propose possible solutions. For data collection a survey of doctoral students and observing their behavior information search situation will be favored. The results of the study will enable a better understanding of community needs and the informational practices of doctoral students from the University of Bamako and could be used by the units of information to improve the supply of information services them.

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.
