The mobile communication market in Taiwan is blooming developing, and the number of mobilephone users is growing up. Nowadays, over 90% of having-a-mobilephone users in Taiwan, even this number are tending toward saturation at present. Therefore, the telecommunication providers expect mobile value-added service can increase the revenue by taking advantage of 3G high-speed transfer rate. But lacking of the ¡§Killer App¡¨, this service doesn¡¦t attract people to use. The ARPU (average revenue per user) doesn¡¦t improve much as we anticipated. The purposes of this study are to realize present situation of mobile value-added service¡¦s development and to develop acceptable content that can be implemented. The study collected literatures and documents to analyze progress of mobile communication system¡¦s development and present situation of mobile value-added service¡¦s development, furthermore, make the development strategy of mobile value-added service according to the new product development procedure, then test user acceptance by TAM. The study proposes ¡§User-generated Content¡¨ as the new mobile value-added service. This service has 6 characters: ¡§highly personalized¡¨, ¡§timely¡¨, ¡§ease of use¡¨, ¡§rich information¡¨, ¡§highly integrated¡¨, ¡§cross platform¡¨. The result of TAM questionnaire proves that ¡§perceived usefulness¡¨ is positive influenced by ¡§timely¡¨, ¡§mobility¡¨, ¡§personalization¡¨, ¡§perceived ease of use¡¨, and ¡§attitude toward using¡¨ is positive influenced by ¡§perceived usefulness¡¨, ¡§perceived ease of use¡¨, ¡§relatives and friends¡¦ influence¡¨, ¡§price¡¨.

As the size and complexity of a software system increases, the design problem goes beyond the algorithms and data structures of the computation. Designing and specifying the overall system structure -- or software architecture -- becomes the central problem. A system's architecture provides a model of the system that hides implementation detail, allowing the architect to concentrate on the analyses and decisions that are most crucial to structuring the system to satisfy its requirements. Unfortunately, with few exceptions, current exploitation of software architecture and architectural style is informal and ad hoc. The lack of an explicit, independent characterization of architecture and architectural style significantly limits the extent to which software architecture can be exploited using current practices. Architecture Description Languages(ADL) result from a linguistic approach to the formal description of software architectures. ADLs should facilitate building of architectures, not just specification. Further, they should also address the compositionality, substitutability, and reusability issues, which are the key to successful large-scale software development. A software architecture description language with a well defined type system can facilitate compositionality, substitutability, and usability, the three keys to successful large-scale software development. Our contribution is a new software architecture description language, TriSL, which supports these features. In this talk we describe the design and implementation of TriSL and its type system. We demonstrate the power of our language and its expressiveness through case studies of real world applications.

Regardless all the advantages of MPs, it has not reach the sizable customer base. In this paper, we examined the core drivers of using mobile payments (MPs) in restaurant industry from the consumers' perspective. Based on the Technology Acceptance Model (TAM), we developed a six factor model to reveal the determinants of consumers' intention to use MPs in restaurant. Security, subjective norm, compatibility with lifestyle, and previous experience with MPs were added to the traditional two factor TAM model (usefulness and ease of use). 300 respondents were recruited from an online survey agency and 258 valid responses were included in the data analysis. The regression results suggested that consumers' intention to use MPs in restaurants is influences by compatibility with lifestyle, usefulness, subjective norm, security, and previous experience in MPs. Lifestyle compatibility was found as the strongest determinant of consumers' acceptance of MPs in restaurants. However, ease of use was not a significant predictor of MPs usage in restaurant. Based on the findings, the study provided several implications to the restaurant industry. Five factors (compatibility with lifestyle, usefulness, subjective norm, security, and previous experience in MPs) can serve as a guideline to encourage consumers' adoption of MPs in restaurant industry. Industry practitioners can develop advertisement catered to a trendy, innovative, tech-friendly generation who desires the flexibility that MPs give and is willing to have everything in one device. MPs should be developed to provide an added value to the user. It is also important to increase the source credibility of social information to improve communication campaigns. Finally, restaurant staff could be trained in guiding and assisting consumers in their first experience with MPs.

In 2012, federal legislation introduced a requirement for formal transportation asset management (TAM) in transportation agencies. The law specifically requires agencies to develop TAM plans and implement TAM programs in their decision-making processes. The history of national policy development for (TAM) and research in policy implementation and organizational theory have shown that program sustainment is not easily achieved. Often, agencies can respond to this kind of legislative mandate with ineffective efforts to achieve legitimacy that reduce the likelihood for the program to be sustained in the long-term. This presents a challenge because without sustainment, the benefits of TAM, which are mostly long-term, may not be fully realized. The objective of this work was to develop a conceptual framework to guide transportation agencies to review their TAM implementation practices and identify opportunities to enhance long-term program sustainment. The conceptual basis for the framework comes from a synthesis of transportation, policy and program implementation, and change management literature, supported by insight from a panel of practitioner and academic experts. The TAM Implementation Review Framework (TIRF) incorporates seven themes of implementation factors that can promote sustainment of TAM practices impacting the social, organizational, and programmatic elements of implementation. The TIRF was applied in case studies to review the TAM implementation processes of three Departments of Transportation (DOTs) resulting in different kinds of information on how implementation activities address factors related to program sustainment. These results can steer future implementation activities in DOTs towards increased probabilities of achieving long-term program sustainment. The primary contributions of this work lie in the development of the conceptual framework and approach to enhance TAM implementation by emphasizing the people and organizational elements of TAM, alongside with the technical. In practice, the TIRF offers agencies a review and planning tool to support TAM implementation decision making and to promote program sustainment. The output is being proposed as a foundational element in the development of an evidence-based catalog of TAM implementation strategies. This can facilitate inter-agency knowledge sharing by providing a platform for systematic documentation of implementation experiences to support broader adoption of strategies that can contribute to increased program sustainment.

Organizations are attempting to leverage their knowledge resources by integrating knowledge sharing systems, a key and new form of which are social computing tools. A large number of these initiatives fail, however, due to employees' reluctance to use, contribute content to, and share knowledge through such tools. Although research regarding one's motivation to share knowledge is extensive, there has been little research examining social computing systems, especially from the seeking and contributory perspectives—the two distinct, but closely interrelated facets of knowledge sharing. Motivated by such concerns, and by incorporating knowledge-seeking and knowledge- contribution perspectives in a single study, this research develops and empirically examines a theoretical model to explain what motivates employees to seek, contribute and share social tags using Enterprise Social Tagging Tools (ESTTs). Two research phases were employed to address the research objective. The goal of the first phase of the study was to explore factors affecting users’ tagging behavior in online social tagging tools. An extensive literature review was synthesized and a preliminary theoretical model emerged. A pilot study was conducted yielding 184 responses featuring eight different online social tagging tools. Mostly, the preliminary theoretical model showed positive influence on users’ tag behavior with a special focus on the newly developed concepts of information retrievability, information refindability. The goal of the study’s second phase was combining the results from the first phase with motivational theories to build and validate a belief-based and socio-organizational model that can explain employees’ tag seeking, contributing, and sharing behavior in ESTTs. The model was developed by employing theories such as Theory of Reasoned Action (TRA), Theory of Planned Behavior (TPB), Technology Acceptance Model (TAM), and social exchange theory. Through a large-scale survey (n=481) in two large Information Technology (IT) companies, the model was validated. The results speak to the importance of the three newly developed factors impacting employees’ tag seeking, contributing and sharing behavior. These factors are uniquely context-specific reflecting actual features of social tagging tools and potentially social media in general. Particularly, the results reveal that employees' tag seeking behavior is affected by their perception of the ESTTs in terms of enjoyment, information retrievability, ease of use, and managerial influence. In the context of tag contribution and sharing, the results show that employees contribute and share tags because of their perception of information refindability, ease of use, altruism, and pro-sharing norms. Differences among the seeking, contributing and sharing model have implications for future research and practice. / The thesis investigates employees' motivation to participate in enterprise social tagging tools. It describes and validates a conceputal model composed of three types of motivations: technical, social, and organizational.

Mobile payments is a topic that is gaining increased attention in both research and in the media. Trends have been identified that show an increase in the use of both smartphones and mobile applications. At the same time there has been a decrease in cash use, with a move towards alternative cashless means of payment in Sweden. Existing research has focused on this type of trend research and also looking at mobile payments in a general sense. There is a gap in the research where the acceptance of mobile payment applications are receiving very little to no attention. The purpose of this thesis is then to identify the determinants of the acceptance of mobile payment applications. Using existing Technology Acceptance Model research on mobile payments, 13 hypotheses were proposed that all related to various factors of acceptance of mobile payment applications. A questionnaire was constructed to test these hypotheses and distributed using convenience sampling. The hypotheses and questionnaire was used to construct a conceptual model in AMOS, where we subsequently used multiple regression analysis to analyze the gathered data. This resulted in 6 hypotheses being accepted and 7 hypotheses being rejected. The factors that was shown to have a significant effect on the acceptance of mobile payment applications, ranging from largest effect to the least are: attitude towards using mobile payment applications, perceived usefulness of mobile payment applications, the subjective norm of the individual, perceived ease of use of the mobile payment application, perceived credibility of the mobile payment application and perceived compatibility of the mobile payment application.
