With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural areas are rather restricted from deploying communication services due to the rough natural environment, and the shortage of rudimentary communication facilities and technical personnel. Appropriate models for building rural wireless networks and a concomitant simulation environment are, therefore, expected to enable the construction of technologically-optimal and economically-efficient networks in specified rural areas.<br /> <br /> The research has set up two independent models, one for the economic need and the other for the technical need of building networks in rural areas. One model was the Impact of Telecommunications Model, which disclosed the importance of building a wireless network in specified rural areas by choosing an economic parameter to forecast the profitability of the network. The other was the Service Model, which collected primitive data from given rural areas and abstracted these data by flowing them through four technical layers to form the predicted technical wireless network. Both of the models had been applied to real-world cases to demonstrate how to use them.<br /> <br /> A simulation environment was finally designed and implemented to realize the above two models for the sake of instantiation. This environment could simulate the specified rural network by constructing a wireless network on the invented areas and evaluating its quality and economic efficiency. It was written in Scilab simulation language, which was an open source.

Internet and mobile phones are two of the most popular innovations of information technology in recent times. As the number of Internet and mobile phone users continues to grow, it is expected that mobile services that enable e-commerce would provide new business opportunities constantly. With the expected rapid growth of mobile commerce, factors affecting the adoption of relative technologies have recently turned into a critical topic of business research. / While the final success of 3G networks is still to be determined, GPRS-enabled mobile phones have been publicly available since 2001. In the area of mobile technologies that enable mobile commerce, GRPS is currently the most popular mobile phone service that allows users to execute business transactions through Internet. The innovation of GPRS technology offers mobile services with the advantages of low cost and fast speed, and thus becomes an ideal tool to be used for mobile commerce. Realizing the advantages of GPRS and the importance of relative studies to the mobile industry, this research aimed to address the issues of user acceptance and behavioural intentions on GPRS-enabled mobile phones. / In Taiwan, the penetration rate of mobile phone had reached 114% and made the number one in the world. This high penetration rate made Taiwan a practical site for studying mobile technology acceptance. This research was therefore proposed to be conducted in Taiwan to better understand the user adoption of mobile phones. This study first reviewed the development of mobile technologies as well as the theoretical background for the research. The model of decomposed theory of planned behaviour was then adopted as the research framework based on previous empirical studies of new mobile services. Fourteen hypotheses were developed to address the key research question as to the factors affecting the adoption of GPRS mobile phones in Taiwan. An online questionnaire was implemented for data collection from Internet users. Data analysis followed for hypotheses testing based on structural equation modelling. The study results show that cost and speed, perceived usefulness, image, risk, compatibility, peer influence, self-efficacy, and facilitating conditions are found to significantly influence the adoption intentions of GPRS technology. / This study on the adoption of GPRS technology is important for enterprises that are planning to offer mobile services. The results of this research may offer directions for industrial practitioners in the field to improve the diffusion and acceptance of GPRS. Such research results can also provide knowledge for business executives to better understand the primary concerns of mobile customers and thus develop mobile services and technologies more strategically. Other managerial implications and suggestions for future research are also discussed at the end of this dissertation. / Thesis (DBA(DoctorateofBusinessAdministration))--University of South Australia, 2005.

One of the most persistently challenging topics in the Information Systems (IS) field continues to be how to improve understanding and gain a useful perspective on technology adoption and implementation. Researchers attempting to make progress in this field have had to grapple with the limited explanatory power of recognised diffusion theories and the fragmentation of research on uptake of innovative technology across a number of disciplines. / This research project addresses the fundamental question of how to improve technology adoption and implementation-referred to in this thesis as the innovative technology uptake (ITU) problem. Tackling the ITU problem required development of a coherent explanatory theoretical framework, which needed to be appropriate for the investigation of diffusion processes in the more complex environment of a market. Evolutionary Diffusion Theory (EDT) offered this project an appropriate basis as well as a broader investigative approach for reviewing technological change. Originally formulated in the field of Evolutionary Economics, EDT describes economic phenomena with a particular focus on situations of change, open systems and innovation processes. Although EDT- and the set of axioms derived from the theory- can be applied to many fields, in this project it was restricted to exploring the ITU problem in Government to Business (GB2) implementations of e-business technologies in the Australian food industry. / This study of uptake of innovative technology in the Australian food industry between 2000 and 2003 produced a significant body of empirical data. The major case study applies the conceptual framework to a review of an online system for facilitating access to export documentation (known as EXDOC) and its phased implementation by a government agency, the Australian Quarantine and Inspection Service (AQIS). The EXDOC case study provides the basis for an exploratory analysis of current Australian practices in the uptake of innovative G2B technology as well as a review of the ITU problem in relation to policy and sustainable technology issue / This thesis produced the following deliverables: A conceptual framework derived from axioms based on Evolutionary Diffusion theory which adds considerably to understanding of influences on uptake of innovative G2B technology in an IS research context; A simple integrated framework for understanding not only why technology innovations fail but also the conditions under which they can form durable communities; A set of holistic guidelines proposed to assist other Australian government agencies currently implementing innovative online technology got G2B service delivery. / This research paper suggests that Evolutionary Diffusion provides a unified theory best suited to understanding the principle influences on the speed and specific course of uptake of G2B innovative technology in the Australian food industry. / Thesis (PhD)--University of South Australia, 2005.

The dissolution profile of orally delivered drugs can be controlled through the use of osmotically controlled drug delivery devices. The most commonly used device is the osmotic tablet, which is essentially a tablet core that is coated with a rate-limiting semipermeable membrane. The feasibility of applying a coating onto a tablet using dense gas techniques was studied. Two different coating materials, polymethymethacrylate (PMMA, Mw = 120,000 g/mol) and cellulose acetate (CA, 39.8 wt% acetyl content) were applied onto an 8 mm osmotic tablet core using the Gas Anti-solvent (GAS) process. For PMMA, the pressurisation rate, coating temperature and volumetric expansion of up to 250% had minimal effect on the coating quality. The concentration, solvent type and the use of polyethylene glycol (Mw = 200 g/mol) had a more pronounced effect on the coating. The coating process was optimised to apply a smooth and uniform coating with a 50 ??m thickness. For CA, the pressurisation rate and the coating temperature had little effect on the coating that was applied. The process was more sensitive to a change in the concentration of the solution and the volumetric expansion that was used. It was found that the concentration could not be increased too much without affecting the coating quality. A CA coating was applied onto a PMMA-coated tablet using the optimised conditions. The thickness in the tablet coating increased by 10 ??m. Dissolution tests of the uncoated and coated tablets were carried out. The CA coatings were found to be insufficient in limiting the rate of water entering the tablet and performed similarly to an uncoated tablet core. The PMMA coatings were found to limit the rate of delivery of the model drug. However, variations in the PMMA coatings resulted in an inconsistent delivery profile across batches. The tablets coated with both PMMA and CA had a delivery rate in between that of uncoated and PMMA-coated tablets, indicating that the application of the second coating had compromised the initial PMMA coating.

Both, market forces and public systems are unable to provide remote rural communities of developing countries with contextually relevant and appropriate technologies. This is because the number of people and their incomes are too low, to constitute either a market or a political constituency. Consequently, development aid and development projects emerge as the primary means of introducing new technologies to these regions. However developmentalism is heavily inscribed with economic determinism resulting in the conception of technologies that are focused at the level of the nation state and whose primary objective is to increase its productive and consumptive capacity in an attempt to jumpstart economic growth. This results in mass technologies that are inherently violent, ecologically damaging and which restrict individual freedoms. Furthermore, these technologies end up replacing rather than building upon the only resource in which the poor are rich; traditional knowledge and the ability to innovate and contextualize technologies to their own local worlds. How can we disembed the conception of technologies from development aid and build upon the resources of the poor instead of seeking to replace them? How can we create a knowledge network that assists in taking the technological innovations of the poor from concept to market and which protects intellectual property rights and allows follow-on innovation. The emergence of networked computing accompanied by new paradigms of production such as peer to peer and open source along with a rethinking of the ‘commons’ which not only reduces development costs but also geographic barriers to collaboration presents us with a unique opportunity to satisfy these conditions. This thesis will therefore explore the feasibility of engaging with Open Source methodologies for facilitating user led technology innovations in developing countries. This includes the many operational and disciplinary challenges that must be addressed before seeking to contextualize Open Source methodologies for the Industrial Design process. It will investigate the intrinsic character of computer software and its development process for insights that can help determine if the open source methodology can be extended to Industrial Designers and the Industrial Design discipline. If yes, what forms of contextualization would be required? Finally, this study will conclude by outlining guidelines and an architecture for the conception of an Open source Community that facilitates user led technology development. / Master of Engineering (Hons.)
