Text in English with Abstracts in English and Afrikaans / Health promotion is an educational tool that can be used to educate and create awareness of health issues through various media forms. The purpose of this study was to explore the use of TB Proof South Africa‘s Facebook page in creating TB awareness. The literature on TB, social media, health promotional campaigns and health promotional models was reviewed to contextualise this study. A qualitative case study approach was used to collect data from TB Proof South Africa‘s Facebook page. Data was collected using three data collection methods; namely, online ethnographic observation, textual analysis and visual analysis. The findings indicate that TB Proof South Africa‘s Facebook page creates awareness of TB. Results from this study also suggested collaboration between South African healthcare professionals and traditional health practitioners in the fight against tuberculosis. The study advocates the need for comparative studies to explore the use of other health-related Facebook pages. / Gesondheidsbevordering is ʼn opvoedkundige werktuig wat gebruik kan word om op te voed en bewustheid van gesondheidskwessies deur middel van verskeie mediavorme te skep. Die doel van hierdie studie was om die gebruik van TB Proof South Africa se Facebook-blad in die skepping van TB-bewustheid te verken. Leesstof oor TB, sosiale media, gesondheidsbevorderingsveldtogte en gesondheidsbevorderingsmodelle is beoordeel om hierdie studie te kontekstualiseer. ‘n Kwalitatiewe gevallestudiebenadering is gebruik om data van TB Proof South Africa se Facebook-blad in te samel.

Die studie bepleit die behoefte aan vergelykende studies om die gebruik van ander gesondheidsverwante Facebook-blaaie te verken. / Communication Science / M.A. (Communication)

The importance of agricultural knowledge systems (AKS) especially in rural communities cannot be overemphasized. AKS are important for creation, sharing and enhancing access and usage of agricultural knowledge. They link agricultural research and farms; increase adoption of good agricultural practices; improve the performance of agricultural marketing systems; and enhance effective post-harvest management. Despite the importance of agriculture to the economy and livelihoods of majority of Tanzanians, there is a consensus from scholars that the sector has been performing poorly. This is partially due to limited access to agricultural knowledge resulting into irrational decisions on agricultural activities thus dwarfing the sector. The modified Knowledge Management Processes Model guided the study in investigating how AKS can be strengthened to enhance access and usage of agricultural knowledge among stakeholders. The study adopted a pragmatic paradigm and used mixed method research by applying a survey, key informant interviews, focus group discussions (FGDs) and document reviews. Structured questionnaires were administered to 314 farmers while key informant interviews involved 57 respondents among village executives, councillors, input-suppliers, information providers, buyers, agricultural extension officers and researchers. Moreover, three FGDs involving 24 farmers were conducted. Qualitative data were analysed through classical content and constant comparison analysis, while SPSS software was used to analyse quantitative data. Quantitative and qualitative data were mixed during analysis, interpretation and discussion of results. The study identified farmers, the private sector and the government as major actors, but not working in unison. Most actors used human based systems while few used ICT and paper based systems. Actors needed agricultural knowledge on weather, farm preparation, seeds, crop maintenance, post-harvest practices, agricultural marketing and credits. Most actors shared agricultural knowledge through face-to-face interactions and mobile phones, few through internet. It was concluded that poor linkage among actors limited accessibility of agricultural knowledge. To improve accessibility to agricultural knowledge, a model for strengthening AKS usage is proposed. It is recommended that actors should be linked together and involved in enhancing access and usage of agricultural knowledge. Moreover, the proposed model should be validated before applying it. / Information Science / D. Litt. et Phil (Information Science)

The purpose of this study was to develop a conceptual framework to aid in the reduction of the taxation gap in South Africa (SA) through the use of third-party data and information technology. In order to develop a framework to prevent non-compliance, an understanding was required of the areas that would enable such a framework to be successful. Since governance, risk and compliance (GRC) is an emerging area in the corporate and information technology domain, organisations, including revenue bodies, are confronted with an increased risk and a growing number of regulatory, legal and other compliance requirements. The frame of reference for integrated governance, risk and compliance was used as base to determine the areas that had to be included in the new feasibility framework for the South African Revenue Service (SARS) in order for the framework to enhance compliance. Thus, the frame of reference for integrated governance, risk and compliance provided a contextual understanding of the areas that had to be reviewed in order to ensure that the framework that was developed adhered to all aspects that would make it a suitable and acceptable framework within SARS. Since the new conceptual framework will be used to address compliance and risk management, existing frameworks had to be considered – one in particular, namely the Compliance Risk Management Process as described by the Organisation for Economic Co-operation and Development (OECD). The OECD guidance note outlines compliance risk management as a structured iterative process for the “systematic identification, assessment, ranking, and treatment of tax compliance risks” that will enhance decision-making. This structural process is depicted in the Compliance Risk Management Process which can be used by revenue bodies, including SARS. Thus, once the different areas had been identified, discussed and understood, the existing Compliance Risk Management Process as described by the OECD was discussed to identify how the new conceptual framework that would be developed as part of this study could enhance this existing framework. Finally the framework was developed by making use of an extended literature review on the main characteristics of ‘big data’, which was then tested with the use of two selected case studies and concluded with a comparative analysis of the case studies. Overall, the framework will aid to determine whether it is feasible to continue with a project to use third-party data and information technology to automate the detection and prevention of taxation gaps before spending too many resources without any significant effect on diminishing the taxation gap. It is therefore recommended that SARS implement this new feasibility framework as a pre-check in order to determine whether:  there is third-party data available for a specific type of transaction that will result in the reduction of the taxation gap;  the third-party data is reliable and usable. If not, which changes are required from the third party in order to ensure that it can be linked to specific taxpayers (for example, such as capturing additional data or changing the format of existing data that had been captured in order to ease the extraction process);  any tax acts or legal aspects should be enhanced to ensure all relevant taxpayer information is available from a specific third party; and  both organisations (SARS and the third party) have the relevant information technology to ensure SARS can extract, store and manipulate the data in a timely fashion in order to obtain the maximum effect. In conclusion, a new feasibility framework was developed as part of this study in order to aid SARS with the reduction of the taxation gap by using third-party data and information technology. The purpose of the new feasibility framework is to identify whether there is third-party data available and whether any changes are required to the data in order to provide SARS with a mechanism to link it to specific taxpayers. This will provide SARS with guidance as to the steps that are required in order to automate the process of collecting third-party data through by using information technology. The feasibility framework would also indicate whether it is feasible to continue with such an automation project before exhausting too many resources without any significant effect on reducing the taxation gap. / Taxation / M.

Information and communication technology (ICT) advances have dramatically changed teaching and learning processes. This study investigates the use of ICT in teaching and learning with the objective of establishing whether teachers are utilising the skills acquired through the Sci-Bono Discovery Centre training. The study sample comprised of 30 secondary school teachers who were trained in 2012 and who were teaching mathematics and/or physical science. The participating teachers were from schools that fell within the Johannesburg North and Johannesburg East regions of the Gauteng Department of Education (GDE). An overall understanding of reviewed literature on the use of ICT in teaching and learning contributed to the preparation of the research survey questionnaire and interview questions. A research survey design using a multi-methods approach allowed both questionnaires and interviews. The questionnaires were analysed using a simple descriptive data analysis technique. The interviews were conducted with 12 of the initial 30 participants over a period of two weeks in a one-on-one setting. The recorded interviews were transcribed and analysed using a thematic content analysis technique. The results of both quantitative and qualitative analysis are presented using charts and tables. The research findings identified issues such as the need for teachers to maintain a positive attitude towards the use of ICT in teaching, and for schools to create a conducive teaching environment for effective use of ICT in the classroom, including the availability of computer resources. The study provides recommendations including the provision of ICT coordinators at schools, and the provision of an ongoing teacher ICT training programme. / School of Computing / M. Tech.

This study investigates the usability of the South African Super 14 Rugby franchise web sites. Web site usability is a measure of a web site user’s experience when visiting a web site. A web site user’s experience will determine how well a web site’s goals are achieved. The relevant web site goals are, having as many visitors as possible, both unique visitors and repeat visitors, and ensuring that those visitors stay on the web site for as long as possible. This study uses data generation method triangulation to enhance the validity of the findings. The data generation methods are an e-mail questionnaire survey and an expert group consensus method called the Delphi Method. This study shows that within each web site and across all five web sites, there is poor usability consistency. Management guidelines and recommendations for improvements to these web sites are presented, so that the web site goals can be achieved. / Computer Science / M.Sc. (Information Systems)

E-commerce has increased substantially, as e-retailers engage with consumers online. Users require more than products and quality service; they also expect a good user experience. User experience is affected by branding, functionality, navigation, content, aesthetics and usability. This study investigates the attainment of better user experience on e-commerce websites. A dual-method usability evaluation approach – usability testing with end-users and heuristic evaluation by experts – was employed to obtain a holistic picture of how usability aspects support or hinder the user experience. Usability testing provided insights into detailed interface issues and the type of content and journey that users prefer when making a purchasing decision, while heuristic evaluation was mainly directed at overall user interface and interaction factors. In a complementary way, each method identified a high number of usability problems. Key findings are summarized, and design guidelines are identified that can facilitate the development of e-commerce websites to promote user experience. / E-handel het aansienlik toegeneem, soos e-kleinhandelaars by verbruikers aanlyn betrokke raak. Gebruikers verlang meer as produkte en kwaliteit diens; hulle verwag ook 'n goeie gebruikerservaring. Gebruikerservaring word deur ‘branding’, funksies, navigasie, inhoud, estetika en bruikbaarheid beinvloed. Hierdie studie ondersoek die bereiking van beter gebruikerservaring op e-handel webwerwe. 'n Dubbelemetode bruikbaarheidsevaluering benadering – bruikbaarheidstoetsing met eindgebruikers en heuristiese evaluering deur kundiges – is gebruik om ‘n holistiese beeld te verkry van hoe bruikbaarheidsaspekte gebruikerservaring ondersteun of verhinder. Bruikbaarheidstoetsing lewer insigte in gedetailleerde koppelvlak kwessies en die tipe inhoud en roete wat gebruikers verkies wanneer hulle 'n aankoop maak, terwyl heuristiese evaluering hoofsaaklik gerig is op algehele gebruikerskoppelvlak en interaksie faktore. Op 'n komplementêre manier, het elke metode' n groot aantal bruikbaarheidsprobleme geïdentifiseer. Belangrike bevindings word saamgevat, en ontwerp riglyne is voorgestel wat die ontwikkeling van e-handel webwerwe fasiliteer wat gebruikerservaring bevorder. / Computing / M. Tech.

The research aimed to assess the feasibility of using podcasts in mobile devices to teach research proposal writing for masters’ students of University of South Africa. To aid in this, a general objective was developed which was supported by specific research objectives that guided the study. The research looked at the evolution of open distance learning (ODL) including the use of M-learning. I reviewed literature on the history of podcasts as an entertainment tool being highlighted as a revolution in the academic world especially in the area of distance learning. To create a foundation to give strength to the use of podcasts, theories of education were evaluated and criticised to give reason and foundation for the use of podcasts as a technology to support teaching and learning in ODL. All major aspects of learning were traversed in the theoretical aspect. This is in a bid to assess the ability of the use of podcasts to meet the needs of the learners. A methodology for conducting the research that included the deployment of a pilot project for the research proposal writing module in year 2011-2012 class was developed and justified accordingly. The use of both qualitative and quantitative methods was necessitated by the objectives of the research. This was implemented at data collection and analysis stages of the research. The analysis was fruitful and successful for that matter, giving reasonable backing to the proposal by the researcher of adopting the use of podcasts using mobile devices. The analysis deemed the pilot project successful for the period within which it was operated. Hurdles or challenges were present and the study gives them as majorly, the lack of sufficient skills to handle the content of the website, that is, generally, the use of the technology. Also, the study pinpoints that the availability of mobile devices is also a challenge that the students will face. Recommendations were derived from the challenges and include a framework that should be used in creating a podcast support system that will be based on the findings to create a successful project. Regarding the objectives of the study, the conclusion that indeed it is feasible to use podcasts to teach research proposal writing in Unisa is valid. / Curriculum and Instructional Studies / D. Ed.

CAPES / Esta dissertação aborda como profissionais do jornalismo, através das práticas do cotidiano, se apropriam de artefatos e tecnologias computacionais para trabalhar com Jornalismo Guiado por Dados e, especificamente, com visualizações de dados. Para isso, considera-se que é no cotidiano que as tecnologias são apropriadas por quem as usa, e que este uso leva as tecnologias a uma estabilização, na qual elas deixam de ser percebidas como um elemento estranho. Os modos de uso dos artefatos também são considerados enquanto elementos construtores de identidades. O objeto principal da pesquisa são seis profissionais que fazem uso de artefatos e técnicas do Jornalismo Guiado por Dados no seu dia a dia. Através de entrevistas e observações, foram levantadas algumas maneiras através das quais as práticas e apropriações de tecnologias constroem as identidades de quem faz uso delas e levam os artefatos à estabilização. A análise das práticas do cotidiano colaboraria para uma visão menos instrumentalista no desenho de artefatos e também no ensino de técnicas, legitimando assim os modos de uso de cada pessoa. Para entender essas práticas do cotidiano, são apresentados os conceitos de “táticas” e “estratégias” com o objetivo de situar as relações de poder do cotidiano e como as pessoas podem subvertê-las, e conceitos dos estudos em Ciência, Tecnologia e Sociedade como SCOT – construção social da tecnologia – e códigos técnicos, para analisar os processos que levam à estabilização de uma tecnologia. Relacionando esses conceitos com o jornalismo, é analisada a conotação de neutralidade dos grandes conjuntos de dados e comparando-a com a ideia de neutralidade da tecnologia. O Jornalismo Guiado por Dados é então relacionado a algumas taxonomias de gêneros e formatos jornalísticos, e é apresentado um breve histórico do uso do computador no jornalismo, para situá-lo dentro do jornalismo de modo geral e nas identidades jornalísticas que são construídas através das tecnologias consumidas no cotidiano. Por sua vez, é apresentado como os produtos jornalísticos derivados de grandes bases de dados propõem outro tipo de relação entre o jornalismo e o público, especificamente através da visualização de dados. São consideradas as possibilidades da visualização como forma de explorar e/ou comunicar grandes conjuntos de dados, assim como formas de leituras que elas propiciam. São descritos alguns processos para produzir visualizações de dados e mostrados exemplos de visualizações usadas no jornalismo, além de descrições de ferramentas de software usadas no Jornalismo Guiado por Dados. Como conclusão principal, defende-se que a legitimação das táticas, assim como uma visão menos instrumentalista e determinista do computar e de outras tecnologias, colaboraria para que mais pessoas se aproveitem dos recursos do Jornalismo Guiado por Dados e das visualizações. / This dissertation looks at how journalism professionals, through everyday practices, appropriate artifacts and computational technologies to work with Data-Driven Journalism and, specifically, with data visualization. For this, we considered that it is in everyday life that technologies are appropriated for those who make use of them, and that this use leads technologies to a closure or stabilization, in which they are no longer perceived as a foreign element. We also consider the way people make use of artifacts as elements that construct identities. The main study subjects are six professionals that make use of artifacts and techniques related to Data-Driven Journalism in their everyday life. Through interviews and observations, we collected some ways through which people appropriate technology, and thus takes them to stabilization and build identities. The analysis of everyday practices would collaborate to a less instrumentalist approach in artifact design and technique teaching, thus legitimating the ways each person makes use of technologies. For a better understanding of those everyday practices, the concepts of "tactics" and "strategies" are introduced, in order to situate the everyday power relations and how people can subvert them, as well as concepts from the Science, Technology and Society studies – STS –, such as SCOT – social construction of technology – and technical codes, in order to analyze the processes that lead to the closure of technology. Relating these concepts to journalism, the neutral connotation of large data sets is analyzed and compared to the idea of technology neutrality. Data-Driven Journalism is then related to some taxonomies of journalistic genres and formats, and a brief history of computer use in journalism is presented to situate it within journalism and how journalism’s identities are constructed through technology consumed in daily life. In turn, is presented how journalistic products derived from large databases propose another type of relationship between journalism and the public, specifically through data visualization. We describe some possibilities of visualization as a way to explore and/or communicate large data sets, as well as some different ways of reading they provide. We also describe some processes and tools for producing data visualization in journalism, as well as some software tools used in Data-Driven Journalism. The major conclusion of this study is that legitimating tactics, as well as a less instrumentalist and determinist approach to computing and other technologies, would help more people in making use of the artifacts and techniques of Data-Driven Journalism and data visualization.

The researcher investigated internet usage among students at the University of Nairobi using a quantitative case study method. A questionnaire-based survey was done among 381 students and face-to-face interviews were conducted with the university‟s library staff. The research findings indicate that the students' level of awareness about the internet services offered at the university was high. The students had good basic computer and internet skills; however, they lacked more advanced skills and this negatively affected their use of internet resources. The students used the internet for various purposes, including to study, teach and do research; to communicate; and for social interaction. The major recommendations of the study include providing formal internet training and adequate facilities; implementing a better, inclusive policy on internet use; and better co-ordinated university efforts. Free internet access should be made available to all the university students, if not all members of the university community. / Information Science / M.A. (Information Science)

Indiana University-Purdue University Indianapolis (IUPUI) / The emergence of information exchange and act of offering features through external interfaces is a vast but immensely valuable challenge, and essential elements of learning environments cannot be excluded. Nowadays, there are a lot of different service providers working in the learning systems market and each of them has their own advantages. On that premise, in today's world even large learning management systems are trying to cooperate with each other in order to be best. For instance, Instructure is a substantial company and can easily employ a dedicated team tasked with the development of a video conferencing functionality, but it chooses to use an open source alternative instead: The BigBlueButton. Unfortunately, different learning system manufacturers are using different technologies for various reasons, making integration that much harder. Standards in learning environments have come to resolve problems regarding exchanging information, providing and consuming functionalities externally and simultaneously minimizing the amount of effort needed to integrate systems. In addition to defining and simplifying these standards, careful consideration is essential when designing new, comprehensive and useful systems, as well as adding interoperability to existing systems, all which subsequently took part in this research. In this research I have reviewed most of the standards and protocols for integration in learning environments and proposed a revised approach for app stores in learning environments. Finally, as a case study, a learning tool has been developed to avail essential functionalities of a social educational learning management system integrated with other learning management systems. This tool supports the dominant and most popular standards for interoperability and can be added to learning management systems within seconds.
