A mobile phone solution for ad-hoc hitch-hiking in South Africa

Miteche, Sacha Patrick January 2014 (has links)
The purpose of this study was to investigate the use of mobile phones in organizing ad-hoc vehicle ridesharing based on hitch-hiking trips involving private car drivers and commuters in South Africa. A study was conducted to learn how hitch-hiking trips are arranged in the urban and rural areas of the Eastern Cape. This involved carrying out interviews with hitch-hikers and participating in several trips. The study results provided the design specifications for a Dynamic Ridesharing System (DRS) tailor-made to the hitch-hiking culture of this context. The design of the DRS considered the delivery of the ad-hoc ridesharing service to the anticipated mobile phones owned by people who use hitch-hiking. The implementation of the system used the available open source solutions and guidelines under the Siyakhula Living Lab project, which promotes the use of Information and Communication Technology (ICT) in marginalized communities of South Africa. The developed prototype was tested in both the simulated and live environments, then followed by usability tests to establish the viability of the system. The results from the tests indicate an initial breakthrough in the process of modernizing the ad-hoc ridesharing of hitch-hiking which is used by a section of people in the urban and rural areas of South Africa.

Newsroom convergence at the Mail & Guardian: a case study

Van Noort, Elvira Esmeralda January 2008 (has links)
This case study researches newsroom convergence as a process at the Mail & Guardian newspaper and their online edition the Mail & Guardian Online. It focuses on the reporters’ and editors’ attitudes towards newsroom convergence and on cultural resistance against change; one of the major challenges in the process. With structured interviews, observations and questionnaires it was analysed that communication problems between the newsrooms, different production cycles and time management issues are other prominent difficulties. The case study furthermore provides a snapshot of the convergence phenomenon as a process in a particular South African news organisation. The outcomes could not only assist other news companies with convergence plans but also be used as a pilot study for further research on converged newsrooms in South Africa.

Investigating the use of social networking via mobile phone as an extension tool in small-scale (emerging) agriculture in selected farming communities in the Cacadu District

Atinuke, Jimoh Rashidat January 2015 (has links)
We live in the era in which the internet is now available on the majority of mobile phones at a very cheaper rate. This advancement in technology has created a boom in the use of mobile phone social networking as a primary communication tool - not only for individuals but also commonly used by professionals in most fields. The trends and growing usage of social networking via mobile phone indicate a potentially effective new platform for increasing production especially in agricultural sectors. In this age of information technology, farming communities can be empowered with the latest information and knowledge through mobile phone social networking to enhance agricultural development. The study investigates the use of mobile phone social networking as an extension tool in small-scale (emerging) farmers in selected farming communities in the Cacadu District Municipality of the Eastern Cape of South Africa. Specifically, the study investigates the use of available mobile phone social networks; what they are used for; and the importance and benefits of social networking both generally and to the farming communities. The study further identifies problems inhibiting the use of mobile phone social networking. Other channels through which the small-scale (emerging) farmers acquire agricultural information, aside from via mobile phone, and the type of agricultural information these farmers acquire, are also investigated. This study focuses on the use - and not the testing or adoption of - mobile phone social networking in small-scale (emerging) agriculture. In the exercise to investigate the use of social networking apps via mobile phone, data was collected from 40 small-scale (emerging) farmers using a purposive sampling method. This study used a survey design, exploratory and descriptive research methodologies. Data was captured by administering a questionnaire through personal face-to-face interviews. Descriptive statistics such as simple frequency tables, percentages and bar graphs were used. From the Chi-square testing, it was found that agricultural knowledge levels, internet access and size of production farm land influence the use of social networking by the small-scale (emerging) farmers. However, the result of this study showed that gender, age, other income and educational level of the small-scale (emerging) farmers are not statistically significant determinants of social networking use. Cronbach’s alpha coefficient was found to be 0.95. To establish the strength of associations of the variables, Cramer’s V ranging between 0.04 and 0.9 (signifying relationships from negligible to very strong association) was used. The findings showed that different social networks are used by the farming communities, such as WhatsApp, Facebook, and Blackberry messenger, MXit, Twitter and YouTube. The various uses of these social networks by the farmers are discussed. The benefits and problems inhibiting their use are also outlined. Other sources of acquiring agricultural information by the farmers aside from social networking via mobile phone are examined. The result of the study shows that [agricultural extension officers, other farmers, farmers’ discussion groups, friends and family,] are major sources of agricultural information to the small-scale (emerging) farmers while other sources are television, radio, print media and result demonstrations. The study suggests that to enhance mobile phone social networking to ensure that timely and effective agricultural information is readily accessible to the small-scale (emerging) farmers. These include agricultural extension officers making optimal use of social networking via mobile phone, due to the strong interaction and trust between them and the farmers. This interaction can be instrumental in the effective use of this technology as a resourceful medium for accessing agricultural information to enhance productivity. Proper awareness and understanding of the potential and benefits of mobile social networking by the farmers will motivate the small-scale (emerging) farmers to use the technology for effective agricultural purposes. Also, ensuring the availability of agricultural information to small-scale (emerging) farmers by setting up on-line pages or websites to discuss matters of interest and educate and update farmers on agricultural issues should be encouraged. This may attract the younger generation and the youth to participate fully in agricultural activities - thereby enhancing agricultural development.

Impact of new media technologies on the production of economics news in South Africa : a case study of Fin24.com (www.fin24.com)

Phakathi, Bekezela January 2010 (has links)
New media technology continues to provide journalists with sophisticated tools that are changing news processing and gathering. Economics journalists in particular have grasped the possibilities offered by new media technologies. Thus, this paper offers a theoretical and practical look at how new media technologies have impacted the production and processing of economics news in South Africa, with a particular focus on Fin24.com which is South Africa's biggest online economics news publication. Using qualitative research methods and the case-study approach, this thesis documents the impact of new media technologies on the production of economics news. It draws on Witschge and Nygren's (2009) framework which describes how new media technologies change the nature in which news is produced and processed. New media technologies in this study will refer to the Internet, particularly search engines like Google, social networking sites such as Twitter and Facebook, Blogs as well as mobile telephony. Economics journalism will here refer to all coverage of economics and business-related news. This is because the case study (Fin24.com) covers both business and economics journalism by strict definition. Findings reveal that these new media technologies have not only changed economics newsgathering and processing but also journalistic routines. The findings generally show that new media technologies make it easier for economics journalists to produce the news quickly and efficiently. Indeed, the most distinguishing characteristic of new media is its overall speed, which is both challenging and attractive. The findings also reveal that new media technologies within a newsroom can be problematic in a number of ways, mainly raising issues of accuracy and credibility thus challenging the profession of economics journalism more than ever.

Consumer perception of real-time marketing tool used by retailers in Gauteng, South Arica

Kallier, Safura M. 02 1900 (has links)
Communication is an essential element of any retail business as it is a means of informing the customer about the retailer and the products and services that they offer. The internet and the rapid advancements in technology have provided retailers with various methods of communicating with the customer such as real-time marketing. Real-time marketing, which allows retailers to interact with customers through various means in real time, has already been widely used in businesses around the world. Although many South African businesses are starting to adapt real-time marketing as a marketing tool in their businesses, the perception of consumers regarding real-time marketing has not been investigated in South Africa. The primary purpose of this study was therefore to determine consumers perceptions of real-time marketing used as a marketing tool by retailers in Gauteng, South Africa. A broad and in-depth literature review was conducted on the advent of real-time marketing as a marketing tool and the various tools used by retailers to execute real-time marketing campaigns of retailers. An empirical study was conducted, in which data was collected from consumers of retail stores in the Gauteng province of South Africa by means of a web-based (computer-assisted), self-administered questionnaire. A quantitative approach was followed in order to satisfy the research objectives of the study. The results of this research study indicated that consumers perceived real-time marketing campaigns as clutter. Customers only considered the real-time marketing campaigns that consisted of immediate discounts and that were personalised for the individual customer as valuable to them. / Business Management / M.

An exploratory study on new technology and associated psychosocial risks in adolescents : can digital media literacy programmes make a difference

Van der Merwe, Petro 11 1900 (has links)
This study centres on the psychological effects new digital media, like the internet and cellphones, have on adolescents. Although the internet has enormous benefits, it also poses a host of risks that can make adolescents vulnerable to victimisation and/or developing associated psychosocial problems. Characterisations of adolescents’ social relationships in the internet medium, as well as the investigation of the continuity between digital media literacy and online social behaviours, carry high relevance for developmental psychology. It is during the adolescent period that peer interactions arguably hold the greatest importance for individuals’ social and behavioural functioning. Using a logic model for evaluation, the researcher conducted an exploratory research study on digital media use among adolescent learners aged 13 to 15 years to determine whether schools could guide them to think critically for themselves about the entire realm of these new media. The data were gathered from school principals, teachers, parents and learners from three secondary schools in Gauteng Province, which were purposely selected to represent different socio-economic circumstances. A total of 230 people (n=230) participated in the research. Mixed research methods were employed in this study. The quantitative research methods supported the qualitative research methods. The literature review suggested that current media literacy education, which forms part of the Life Orientation curriculum, does not enable learners to think critically or make informed choices about their behaviour in the digital world – because it incorporates neither ethics nor responsibility. One of the main aims of the study therefore was to investigate the importance of expanding existing media literacy education, namely by incorporating two additional learning categories in the curriculum: Digital Safety and Security, and Digital Citizenship. These additional learning categories were introduced in the form of lessons by the teachers participating in the study. A think aloud strategy was used whereby learners verbalise what they were doing and learning while engaging in the digital media literacy lesson activities. The learners’ verbalisations were used to ascertain what learning was occurring in the classroom. The experimental group demonstrated an increase in critical thinking from pre- to post-evaluation. This research therefore proposes that the signature element of intervention strategies for inappropriate online behaviour be to create a “culture of critical thinking”. This implies greatly reducing the risks cyberspace pose, and at the same time enhancing adolescents’ abilities to use it in ways that create and deepen healthy relationships – in the digital as well as the real world. / Psychology / D.

The influence of digital media use in classrooms on teacher stress in Gauteng schools

Matwadia, Zyliekha 11 1900 (has links)
In 2014, Gauteng Education MEC announced the “Big Switch On” project in which he envisaged paperless classrooms in Gauteng schools over the next three years. He also said that this would see digital media such as iPads and other electronic Tablets replacing textbooks and stationery. He had a vision that the chalkboard would disappear and projectors would take their place. When the MEC for Education introduced the Big Switch On project, he emphasised the positive effects that paperless classrooms will have on the learners. Education authorities were concerned about and wanted to improve the quality of learning and teaching for disadvantaged learners. However, the MEC for Education failed to highlight the possible impact that paperless classrooms will have on educators. It is important that educators are given an opportunity to provide input with regard to the implementation of paperless classrooms. This study will focus on the perceived stress experienced by teachers in Gauteng, whose schools have been part of the Big Switch On project and have had to mandatorily include the use of digital tablets in their classrooms. This study sought to investigate the influence of digital media use in classrooms on teacher stress in Gauteng schools. It is important to conduct a contextual study that explores the perceived stress factors experienced by teachers in the Gauteng schools that were selected in the Big Switch On project. The research from other contexts can only provide general frameworks regarding the constructs involved. It cannot replace the research conducted specifically for the Big Switch On project. The purpose of this study is threefold. Firstly, the Big Switch On project has been introduced in 2015 in seven Gauteng schools, and was expanded to 375 schools in the following two years. For many schools, this is a first time, thereby rendering it a scarcely researched topic. The implications and effects of the project have yet to be considered. Secondly, it is often assumed that the use of digital tablets in the classroom makes teachers lives easier and reduces their workload. The research that will be undertaken will address this question scientifically to make reliable and valid conclusions that go beyond assumptions. Thirdly, related research has indicated barriers and challenges to the implementation of digital tablets in the classroom. The research will address these barriers and make recommendations regarding future implementation of digital tablets in the classroom. In this qualitative study, I chose a multi-site case study with purposeful, convenience sampling. Two secondary schools that were part of the Big Switch On project were selected. The classrooms in the schools had smartboards, the teachers were given laptops and learners were given tablets. Furthermore, a lot of money was spent on the upgrade of the infra-structure of the schools. These schools were chosen as sites to study the influence of digital media use in the classroom on teacher stress. I chose to interview all levels of teachers and principals, which would allow me to make comparisons as well as provide me with data from which I would be able to reflect on my own practices. I chose to gather data by means of semi-structured face to face interviews. The data revealed that teachers were not part of the decision-making process to introduce digital media in the classroom. Although teachers cited benefits, they felt that the challenges were frustrating with the implementation of digital media in the classroom. Teachers expressed that the initial workload increased but felt that it would decrease over time. Whilst teachers felt that the quality of teaching has improved, they indicated that the quality of learning has deteriorated because learners use the tablets for off-task behaviour. Teachers made recommendations that mirrored the recommendations from the literature and if these concerns are addressed, it would make the implementation of digital media in the classroom more effective and at the same time empower teachers. In order to address school effectiveness, one needs optimum levels of commitment and performance from teachers. Therefore, it is important to emphasize any notion affecting the performance capability of teachers and learners and to create stress free working conditions. It is with this in mind that the study was conducted. / Educational Leadership and Management / M. Ed. (Educational Leadership and Management)

Teachers' understanding and use of digital play for language acquisition in Grade R

Van der Westhuizen, Leonie Magdalena 11 1900 (has links)
Teachers tend to use traditional teaching methods, even though young learners are more digitally oriented. The purpose of this study was to analyse teachers' understanding and practices in grade R classes to clarify their use of digital play for language acquisition. The participants consisted of eight grade R teachers at one selected primary school in an urban area that had access to digital technology. Bronfenbrenner's ecological systems theory as a theoretical framework informed this study. This qualitative single case study generated data from teacher participants and their interaction with the learners. The data generation included semi-structured individual interviews, focus group interviews, and non-participant observations. Analyses to answer the research questions were conducted by means of thematic analysis. The main finding was that grade R teachers have some knowledge and understanding of digital play and they are willing to try new games, but they feel they need to know more about digital technology and the use of digital games for language acquisition. Recommendations include the need for the development of more digital games relevant to language acquisition and for teachers to adopt relevant pedagogies to benefit from available digital games. A similar study in a rural area and a comparison between this study and such a study will then be useful in determining teachers' understanding and use of digital play for language acquisition. / Onderwysers is geneig om tradisionele onderrigmetodes te gebruik, selfs al is jong leerders meer digitaal georiënteerd. Die doel van hierdie studie was om onderwysers se begrip en praktyke in graad R-klasse te ontleed, om hul gebruik van digitale spel vir taalverwerwing duidelik te maak. Die deelnemers het bestaan uit agt graad R-onderwysers by een uitgesoekte laerskool in ʼn stedelike gebied, met toegang tot digitale tegnologie. Hierdie studie is geïnspireer deur Bronfenbrenner se ekologiese stelselteorie as ʼn teoretiese raamwerk. Hierdie kwalitatiewe enkelgevallestudie het data van onderwyser-deelnemers en hul interaksie met die leerders gegenereer. Die datagenerering het halfgestruktureerde individuele onderhoude, fokusgroeponderhoude en niedeelnemer-waarnemings ingesluit. Die vernaamste gevolgtrekking was dat graad R-onderwysers oor ʼn mate van kennis en begrip van digitale spel beskik en dat hulle bereid is om nuwe speletjies te probeer, maar hulle voel hulle behoort meer te weet van digitale tegnologie en die gebruik van digitale speletjies vir taalverwerwing. Aanbevelings sluit in: die behoefte aan die ontwikkeling van meer digitale speletjies wat op taalverwerwing betrekking het; en dat onderwysers tersaaklike pedagogieë moet inspan om uit die beskikbare digitale speletjies voordeel te trek. ʼn Soortgelyke studie in ʼn landelike gebied en ʼn vergelyking tussen hierdie studie en so ʼn studie sal dan nuttig wees om onderwysers se begrip en gebruik van digitale spel vir taalverwerwing te bepaal. / Barutiši ba na le go šomiša mekgwa ya sekgale ya go ruta, le ge e le gore baithuti ba baswa ba na le tsebo ya theknolotši.
