M. Tech. Information Networks / The study was undertaken to better understand the vast number of limitations in the use of mobile devices such as screen size, navigation, colour and network limitations. The aim of this study is to identify usability problems within the user interface design of mobile device instant messaging applications. The usability of three mobile instant messaging applications (MXit, Nimbuzz and Whatsapp) will be evaluated on three different high end touch screen smart phones (Apple iPhone 4, BlackBerry Torch 9800 and Nokia N8)

South Africans have had a passionate affair with cellular telephony since its launch in June 1994. But, by far the networks contract-less prepaid service has been an outstanding success, attracting hundreds of thousands of users who could not have otherwise been part of the subscriber base. The prepaid service has made cellular telephony accessible to all, especially the youth/student market. The author investigated the reasons into why students at Cape Technikon chose the prepaid service over the contract service and whether student allowance/ income affected the choice exercised. The prepaid system was voted as being most popular. Income levels had a direct bearing on the choice that students made but other factors such as perception, culture and socio-economic play a role in shaping the choices made. The most important factor to students was that no monthly bills were involved and total control over spending could be exercised. Recommendations to the cellular operators included, projecting a brand personality that attracted the youth and embracing the challenge of building long- term relationships with these customers. / Thesis (M.B.A.)-University of Natal, Pietermaritzburg, 2003.

The topic of this thesis is "Psychosocial effects of the use of mobile phones in children under the age of 12 years." Children in connection with the use of mobile phones are more vulnerable compared to adults regarding the unwilling behavior. Czech public (neither lay nor professional) has not paid sufficient attention to this issue so far. The aim of this work was to monitor attitudes of children to mobile phones, the manner and extent of their use. At last but not at least, it was also the aim to describe the position of mobile service providers to child customers. There was also a market analysis carried out to describe offers, products and services suitable for children. The first part of this thesis describes the current situation in the Czech Republic and is complemented with statistical data of the numbers of mobile phones in the Czech Republic. There are also specifics of children as users of mobile phones mentioned and the risks that are connected to the use of mobile phones, such as reliance on mobile or nomophobia, fears of loss of signal etc. In the following chapters objectives of the research are described, hypotheses and research methodology. The results are shown in graphical form. They are followed by the results of market analysis and expert observations on the issue, the methodology and the research itself. The last part of this thesis is the discussion on the methodology and research results. Research results are also compared and discussed in relation to the literature.

The researcher addressed the need for understanding student perceptions and habits of academic cell phone use within a high school environment in regards to student characteristics. Data were gathered and analyzed in order to answer research questions regarding student perceptions of: (a) the usefulness of cell phones as an academic tool, (b) the use of cell phones within school and outside of school for academic purposes, (c) the encouragement of cell phone use to complete assignments, (d) the potential for distractions within the classroom occurring from cell phone use, and (e) the functionality of cell phones for completion of school work. A quantitative research design was used in this study. Data were collected through the employment of a researcher-designed cross-sectional survey to gather data from one point in time from 175 respondents. Quantitative data were analyzed by frequency distributions and cross tabulations of responses to closed-end survey questions. It was found that students favored the use of cell phones for academic purposes. The implications of this study show the potential for expanded cell phone use as academic tools in high schools as a medium to promote mobile learning.
