While experiencing exponential growth worldwide, Information and Communication Technologies (ICTs) are key factors in business today. The ubiquitous nature of the mobile phone in South Africa and the use of wireless technologies facilitate business in areas where current fixed infrastructure is limited or non-existent, thereby aiding in the development of rural areas. This descriptive study determines what factors will extend the use of mobile phone technology in business. The literature indicates business advantage can be gained from incorporating technology into a strategic framework but in so doing must consider the complexities of the technology and its lifecycle. Currently, e-mail and Internet access would be the most likely applications of data use via Global System for Mobile Communications (GSM). As a technology-based study the methodology used e-mail to deliver a survey targeting staff from the three cellular network operators in Port Elizabeth. The mobile industry and Port Elizabeth were both considered good indicators of technology use and the progression of infrastructure throughout South Africa. The findings indicate that although most mobile phones have the features required by users, the current use of associated data applications is low. Email is the most appropriate application and expected to be significant in 2006. The technology is of strategic importance and can be applied to make idle time productive. Successful use depends on the removal of barriers. In the case of e-mail and Internet access; the most significant of these is the complexity of the initial set-up. Despite the complexity of technology evolution and the challenges of effective business application, substantial gains can be still be realised. Currently, technology is best deployed to meet specialised needs. The expected introduction of third generation technologies herald’s higher data transfer rates, providing the opportunity for more generalised application in business in the immediate future.

Magister Artium - MA / This thesis explores the different ways in which labour migrants in contemporary South Africa make use of cell phones in their daily lives to maintain their love relationships. I start by tracing the history of labour migration and show how the gradual change of migration has played a role in the assertion of labour migrants in their communities in Cape Town. I look specifically into the use of cell phone by Setswana and Sesotho speaking migrants in Delft, Thornton, Brackenfell and Gugulethu. While the focus of the research is on the role of cell phones in maintaining love relationships between migrants and the partners they left behind ‘at home’, I also show how the negotiation of the cell phone in the social lives of migrants helps build wider social networks. The value of the functions of the cell phone through employed communication patterns that encourage social relations and interactions are also the focus of this thesis.

Mobile technologies are the latest technologies in the realm of communication media. They have the potential to flatten the world by making it a place where gender, age, class, race and nationality can no longer hold us back from being heard and being informed. We have learned that these technologies can help to liberate and empower us, and they can lead to a collective cognition as much as they can distract us from what we need to know about the world we live in. In Greece thousands of years ago, a selected number of Greeks had a public space called the Agora to discuss the issues that concerned the public, meaning each and every citizen. They were the first to be able to create the space and place were the word “democracy” could be brought into language; the very word that was used to start a new war in the era of a communication revolution in the 2003 invasion of Iraq. There are still issues that concern the public today such as wars, global warming, homelessness or human rights which are all matters of our collective cognition. However, today in an age of information revolution the public life of people and their collective cognition is being exercised mostly in the virtual spaces of the Internet. Simultaneously, some physical spaces are being abandoned by people. This thesis investigates the possibility of having physical public spaces that are enriched with communication media and not weakened by it. If architects rethink their designs based on a new understanding of the networked society it might be possible to turn this “networked individualism” into a networked collectivism. However, most designed public spaces fail to offer new possibilities that can transform space for the new generation of users. Here, the aim is to understand a new generation of users. Who have they become as a result of new communication media? And how can architects design in a way that responds to this new subject in architecture? / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate

Future generations are built on the children of today. Thus, children's well- being and safety is of paramount importance. Children are making use of mobile devices, such as smart phones, to gain access to the Internet and other data driven mobile services. Children and parents alike are unaware of the risks they are exposed to when accessing such services. A clear lack of parental control over or awareness of this mobile use has been identified in South Africa. Without adequate awareness and successful use of a comprehensive mobile parental control solution, South African children may be at risk. This risk may include exposure to potentially harmful content and/or individuals. This dissertation presents a framework that supports the attainment of a comprehensive mobile parental control solution based on sound research.

This dissertation is composed of research studies that contribute to three research areas including social context-aware computing, internal context-aware computing, and human behavioral data mining. In social context-aware computing, four studies are conducted. First, mobile phone user calling behavioral patterns are characterized in forms of randomness level where relationships among them are then identified. Next, a study is conducted to investigate the relationship between the calling behavior and organizational groups. Third, a method is presented to quantitatively define mobile social closeness and social groups, which are then used to identify social group sizes and scaling ratio. Last, based on the mobile social grouping framework, the significant role of social ties in communication patterns is revealed. In internal context-aware computing, two studies are conducted where the notions of internal context are intention and situation. For intentional context, the goal is to sense the intention of the user in placing calls. A model is thus presented for predicting future calls envisaged as a call predicted list (CPL), which makes use of call history to build a probabilistic model of calling behavior. As an incoming call predictor, CPL is a list of numbers/contacts that are the most likely to be the callers within the next hour(s), which is useful for scheduling and daily planning. As an outgoing call predictor, CPL is generated as a list of numbers/contacts that are the most likely to be dialed when the user attempts to make an outgoing call (e.g., by flipping open or unlocking the phone). This feature helps save time from having to search through a lengthy phone book. For situational context, a model is presented for sensing the user's situation (e.g., in a library, driving a car, etc.) based on embedded sensors. The sensed context is then used to switch the phone into a suitable alert mode accordingly (e.g., vibrate mode while in a library, handsfree mode while driving, etc.). Inferring (social and internal) context introduces a challenging research problem in human behavioral data mining. Context is determined by the current state of mind (internal), relationship (social), and surroundings (physical). Thus, the current state of context is important and can be derived from the recent behavior and pattern. In data mining research area, therefore, two frameworks are developed for detecting recent patterns, where one is a model-driven approach and the other is a data-driven approach.

Although there is a long tradition of research into the relationship between technology and psychological well-being, few studies examine the relationship between mobile phone use and loneliness (Chan, 2015). Far away from their home countries and living in constrained conditions, female domestic workers in particular might experience chronic loneliness, and the mobile phone is a crucial lifeline for them. Using a face-to-face survey of 492 Filipino domestic workers in Hong Kong, this dissertation details how different uses of mobile phones are related to different types of loneliness among this vulnerable population. By differentiating between communicative and non-communicative use of the mobile phone, and between social loneliness and emotional loneliness, the results indicate that Filipino domestic workers' non-communicative use of the mobile phone could decrease their social loneliness, while communicative use neither decreases nor increases both social and emotional loneliness. This finding supports the proposition that mobile phone use is beneficial to individuals' psychological well-being and extends the existing literature on the relationship between mobile phone use and loneliness. Most importantly, there is still no a systematic framework to explain the underlying mechanism connecting mobile phone use and loneliness. Based on the technology paradox and the paradoxical impact of mobile phone use on loneliness, this dissertation develops a two-pathway model to illustrate the underlying mechanism. The first pathway postulates that mobile phone use has a positive influence on loneliness through preference for online communication and problematic mobile phone use, which is based upon the theoretical framework of Davis's (2001) cognitive-behavioral model, Caplan's (2003) theory of preference for online communication, and the literature on the bidirectional relationship between technology and psychological well-being. Grounded in the social convoy model (Kahn &Antonucci, 1980; Antonucci, 2001), the second pathway posits that mobile phone use has a negative impact on loneliness through social network availability and social support. The findings show that the two-pathway model indeed exists. In the first pathway, mobile phone use increases emotional loneliness by leading to problematic mobile phone use. In the second pathway, mobile phone use results in decreased social loneliness through increased social support or through the joint impact of social network availability and social support. This dissertation makes theoretical and practical contributions to the field of mobile phone use, not only by developing a two-pathway model to uncover the underlying mechanism connecting mobile phone use with loneliness, but also demonstrates the technology paradox and the paradoxical impact of mobile phone use on loneliness among the Filipino domestic workers in Hong Kong. It will be worthwhile to replicate and testify this two-pathway model in other populations, such as elders, adolescents, and young adults.
