In 1996, the promulgation of the amended Telecommunications Act initiated a series of liberalization in telecommunication industry. From 1998 to 2000, Taiwan had become the most rapid growth area around the world with 130% compound annual growth rate and had marked a milestone with more than 80% of penetration by the end of 2000. This study focuses on the pricing plans offered by the main operators, CHT, TCC and FET, to analyze the pricing strategies and the competition scenarios with one another. In this study, we, first, gather the pricing plans of the operators and then review the history of the price adjustment. At last, we compare the pricing plans across the boundary of the operators. From the history of the price adjustment and the market evolution, we realize that the new subscribers encouraged by low prices are mostly low in airtime usages. The operators discriminates these low airtime users more in prices under the consideration of market competition and profit gaining. From reviewing the pricing plans of the operators respectively, we find the existence of ¡§redundant¡¨ pricing plans, which might bring the operators extra income. From comparison of the pricing plans offered by the three main operators, we conclude the three players try to lower the competition strength by charging high in different segments.

Economic development is often associated with the adoption of new technologies. The three chapters in this dissertation ask how societies can achieve efficient adoption of these technologies. The first two chapters analyze the dramatic spread of a new communication technology---the mobile phone---in the East African country of Rwanda, using transaction data. Many technologies important for the modern economy are network goods; these goods tend to diffuse inefficiently in the absence of careful policy design. The first chapter introduces a new method to estimate the value of a network good, and to simulate the effects of policies. Economic actors also must decide whether a given technology is worth adopting. The second chapter analyzes how individuals learn about a new technology, by tracing the adoption of a new, cheaper mobile phone plan. The third chapter considers the side effects of new technologies, specifically, how innovation affects dimensions of quality that are not observed by consumers. / Economics

Most companies have some sort of business model showing how they operate their activities,resources, cost and revenues etcetera. What is becoming increasingly emphasised in today'sbusiness is however to integrate sustainability within the business model. Our research willtherefore investigate how companies are attempting to make their business model moresustainable. We have chosen to focus on the mobile phone industry as reports have shown thatthey are a significant contributor to carbon emissions and electronic waste. With this in mind ourresearch question is formulated as follows:"How is the mobile phone industry attempting to innovate their business models towardssustainability?"As we attempt to understand how the mobile phone industry is attempting to innovate towardsgreater sustainability, we have chosen to perform a qualitative study. The material we usedconsisted of reports and web pages as well as interviews with manufacturers of mobile phonesand MNO’s. To analyse the material we had collected, we chiefly utilised a list of materialconcerns specific to the aforementioned mobile phone industry stakeholders, a proposedarchetype system for classifying attempts to innovate the business model to become moresustainable and finally a tool for graphically presenting a business model and its inner workings.Our conclusions show what the companies we have interviewed are attempting to innovate intheir business model. The innovations focus mainly on their partnerships, activities, resourcesand value propositions. By performing this study we contribute to the still young research area ofsustainable business model innovation through providing a snapshot of what our interviewedcompanies are attempting to innovate at the time of our study. Furthermore it also contributes tothe empirical use of the proposed sustainable business model innovation archetypes as we applythem to empirical data in an attempt to classify the data. Through performing both of theseactions we also contribute a proposed way of classifying sustainable business model innovationwithin a business model through the combining of the archetypes and the business model canvas.

A consumer research panel is a representative collection of individuals whose consumption habits are continually monitored by a marketing research company. It is designed to study the behaviour rather than the attitudes of consumers in the fast moving consumer goods (FMCG) sector. The analysed and interpreted reports help the retailer and manufacturing clients to better understand their markets and the changing dynamics within markets which are largely overseen by retail studies. It is shown that consumer research panels have a very high per panellist cost due to the nature of the data collection methodologies currently used being either very labour-intensive with the in-home interviewer visits, or due to the cost of the technology needed when using an in-home audit terminal to scan the barcode of items. The ubiquitous use of the mobile phone begs the question whether this technology, already in the hands of people, could be used as a data collection device. In 2007, Robert Adelmann demonstrated that it is possible to recognise linear barcodes using a mobile phone equipped with a camera and a barcode recognition algorithm. Three requirements are set for a mobile phone to be used as a data collection device in a consumer panel and are indicated by various studies researching each, focused on Gauteng, South Africa. The technology is shown to be quick and accurate enough to be used in everyday barcode scanning albeit not very prevalent among the responding sample. The data communication infrastructure needed to communicate the audited data was found to be 100% present although few of the respondents displayed their interest in joining a research panel based on mobile phones. It is, therefore, recommended that a phone-based consumer panel be used to supplement existing consumer panels to extend in hard-to-reach demographics like the upper-LSM households, and that the privacy and usage concerns raised by the respondents be addressed. It is also recommended that similar studies be conducted in developed economies where required mobile phone technology could be more prevalent. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2010.

In order to support efficient transportation planning decisions, household travel survey data with high levels of accuracy are essential. Due to a number of issues associated with conventional household travel surveys, including high cost, low response rate, trip misreporting, and respondents’ self-reporting bias, government and private agencies are desperately searching for alternative data collection methods. Recent advancements in smart phones and Global Positioning System (GPS) technologies present new opportunities to track travelers’ trips. Considering the high penetration rate of smartphones, it seems reasonable to use smartphone data as a reliable source of individual travel diary. Many studies have applied GPS-Based data in planning and demand analysis but mobile phone GPS data has not received much attention. The Google Location History (GLH) data provide an opportunity to explore the potential of these data. This research presents a study using GLH data, including the data processing algorithm in deriving travel information and the potential applications in understanding travel patterns. The main goal of this study is to explore the potential of using cell phone GPS data to advance the understanding in mobility and travel behavior. The objectives of the study include: a) assessing the technical feasibility of using smartphones in transportation planning as a substitute of traditional household survey b) develop algorithms and procedures to derive travel information from smartphones; and c) identify applications in mobility and travel behavior studies that could take advantage of these smartphones GPS data, which would not have been possible with conventional data collection methods. This research aims to demonstrate how accurate travel information can be collected and analyzed with lower cost using smartphone GPS data and what analysis applications can be made possible with this new data source. Moreover, the framework developed in this study can provide valuable insights for others who are interested in using cell phone data. GLH data are obtained from 45 participants in a two-month period for the study. The results show great promise of using GLH data as a supplement or complement to conventional travel diary data. It shows that GLH provides sufficient high resolution data that can be used to study people’s movement without respondent burden, and potentially it can be applied to a large scale study easily. The developed algorithms in this study work well with the data. This study supports that transportation data can be collected with smartphones less expensively and more accurately than by traditional household travel survey. These data provide the opportunity to facilitate the investigation of various issues, such as less frequent long-distance travel, hourly variations in travel behavior, and daily variations in travel behavior.

Philosophiae Doctor - PhD / The objective of this study was to determine if introducing acceptance and commitment therapy in the prevention of mother to child HIV transmission (PMTCT) program using weekly mobile phone messages would result in improved mental health status of HIV-positive, pregnant women in Nigeria. The study used a quantitative approach using a Solomon four-group (two intervention and two control groups) randomised design to evaluate the impact of an acceptance and commitment therapy program. The study population was 132 randomly selected (33 per site), HIV-positive pregnant women attending four randomly selected PMTCT centres in Nigeria. Two were Intervention and two were Control sites which functioned as Intervention and Control groups. The intervention groups were exposed to one session of acceptance and commitment therapy with weekly value-based health messages sent by mobile phone for three months during pregnancy. The control groups received only post-HIV test counselling.

The information security behaviour of technology users has become an increasingly popular research area as security experts have come to recognise that while securing technology by means of firewalls, passwords and offsite backups is important, such security may be rendered ineffective if the technology users themselves are not information security conscious. The mobile phone has become a necessity for many students but, at the same time, it exposes them to security threats that may result in a loss of information. Students in developing countries are at a disadvantage because they have limited access to information relating to information security threats, unlike their counterparts in more developed societies who can readily access this information from sources like the Internet. The developmental environment is plagued with challenges like access to the Internet or limited access to computers. The poor security behaviour exhibited by student mobile phone users, which was confirmed by the findings of this study, is of particular interest in the university context as most undergraduate students are offered a computer-related course which covers certain information security-related principles. During the restructuring of the South African higher education system, smaller universities and technikons (polytechnics) were merged to form comprehensive universities. Thus, the resultant South African university landscape is made up of traditional and comprehensive universities as well as universities of technology. Ordinarily, one would expect university students to have similar profiles. However in the case of this study, the environment was a unique factor which had a direct impact on students’ learning experiences and learning outcomes. Mbeki (2004) refers to two economies within South Africa the first one is financially sound and globally integrated, and the other found in urban and rural areas consists of unemployed and unemployable people who do not benefit from progress in the first economy. Action research was the methodological approach which was chosen for the purposes of this study to collect the requisite data among a population of university students from the ‘second economy’. The study focuses on the relationship between awareness and behavioural intention in understanding mobile phone user information security behaviour. The study concludes by proposing a behaviour profile forecasting framework based on predefined security behavioural profiles. A key finding of this study is that the security behaviour exhibited by mobile phone users is influenced by a combination of information security awareness and information security behavioural intention, and not just information security awareness.

>Magister Scientiae - MSc / According to the WHO (2017), non-communicable diseases (NCDs) which include stroke, cancer, heart disease, chronic respiratory disease and diabetes is the leading cause of death and is responsible for seventy one percent of deaths worldwide. Beaglehole et al., (2009) reported that management of chronic diseases depends primarily on early detection of early disease, identification of high-risk status, interventions including pharmacological and psychosocial intercessions and long term follow up with monitoring and promotion of adherence to treatment.

This study aimed to examine the possible intrapersonal (i.e., attention, depression) and interpersonal (i.e., social relationships with friends, social relationships with teachers) problems related to mobile phone dependency and their impacts on academic achievement in adolescents in South Korea using a national sample of 2159 middle and high school students (1074 male and 1085 female). A structural equation modeling approach with mediation analysis was employed to test the seven hypotheses drawn from conceptual and empirical bases. Results showed that mobile phone dependency negatively predicted attention and positively predicted depression, which in turn, affect social relationships with friends and both Korean language arts and mathematics achievement. Also, the mediating roles of attention, depression, and relationships with friends were found between mobile phone dependency and the academic achievement of middle and high school students in S. Korea. Based on the findings, implications of the current study and future directions for research were discussed.
