The development of information technology (IT) has made a very different prospect in business administration. Today, more and more companies introduce intranet system to establish internal network. Since the intranet system is really costly, companies should make assessment prudently before and after the investment, but the approaches are extremely limited. This study is to assess system success through employee¡¦s acceptance by exploring the components influence his attitude and behavior. This study uses ¡¦the Unified Theory of Acceptance and Use of Technology¡¦ (known as UTAUT) with some measures modified from the viewpoint of large size manufacturing company and concerning models (TAM and TAM2). 436 samples were taken from more than 8600 employees by stratified random sampling. The major findings are (1) there are 5 key components extracted: Usefulness, Ease of Use, Enjoyment, Social Influence, and Facilitating Condition, (2) the Usefulness and Facilitating Condition influence employee¡¦s behavior intention significantly while Ease of Use enhances the Usage directly, (3) Usefulness is the most important factor of all for employee¡¦s acceptance.

<p> This work is an investigation of user acceptance of a prototype solution utilizing wireless text messaging (or SMS - i.e., short messaging service) to improve people's adherence. Insufficient adherence, also known as medical non-compliance, is a major cause of failure in self-management programs, causing significant losses to all healthcare stakeholders.</p> <p> Innovative mobile healthcare solutions, based on portable devices like cell phones, may address some non-adherence aspects by helping outpatients to follow treatments agreed with their health providers. Although this seems a win-win situation, a verdict on the overall usefulness of such an approach cannot be formulated before exploring outpatient acceptance, as this is a novel technology that targets a new area of implementation. Accordingly, this research investigates key factors that may influence the acceptance of a mobile healthcare solution based on SMS to support improved adherence to healthy behaviour, with special attention to motivation (the 'pro' factors) and perceived risk (the 'con' factors).</p> <p> As a means of investigation, a one-month longitudinal experiment with two groups of subjects (an intervention group and a control group) was utilized. Data were analyzed with quantitative and qualitative techniques: descriptive statistics, partial least squares modelling, and content analysis.</p> <p> Findings show that users are aware of the potential usefulness of such a pioneering application. However, enjoyment is the unique reason for adopting, and perceived financial and psychological risks the main obstacles against adopting, an SMS-based solution for improving adherence to healthy behaviour. Furthermore, a business analysis shows that users are concerned about usefulness features, even when asked about financial aspects.</p> <p> These results, together with encouraging findings about the effectiveness of the application, open the way for medical-led research to investigate if long-term mobile healthcare initiatives customized to patient needs are also beneficial for outpatient adherence and health outcomes.</p> / Thesis / Doctor of Philosophy (PhD)

With the development of online shopping, the number of third-party online payment systems increases. Alipay is a commonly used third-party online payment system among Chinese consumers. The purpose of this study was to explore the factors that affect the users’ acceptance of Alipay among Chinese B2C customers. This study adopts a deductive, theory testing approach. Based on the model of Unified Theory of Acceptance and Use of Technology (UTAUT), a research model and hypotheses were proposed. A survey study was performed with a quota sample of 300 Chinese online shopping consumers. Based on the responses, the hypotheses were tested through statistical analysis. Through testing the hypotheses, it was concluded that: “Social Influence”, “Effort expectancy” were the factors that most prominently could affect B2C user’s acceptance of Alipay. Hence, third-party online systems suppliers should focus on social marketing and increasing the ease of use of the systems to increase user acceptance. Other similar third-party online payment company could take those identified factors as reference in further user acceptance study, and the proposed research model in this study could also help in improving understanding of user acceptance in similar third-part online payment system.

The ever-evolving information technology gives users more opportunities, but also put higher demands on them. The digital agenda of the state and society clarifies the objectives and effects academic libraries’ development. E-books influence the development of organizational, economic, legal and political perspectives.   At the University Library in Gävle work is ongoing. The process is controlled by the acquisition policy which makes it clear that e-books should be purchased if possible. By offering e-books including textbooks it expands the availability for student demands. It is one of University Libraries fundamental tasks.   The curiosity about how this work is received by students is the purpose of this thesis and addresses the questions concerning what affects students' acceptance, perception, attitude and usage of e-books in studies at the University of Gävle?   Through an online questionnaire based on a theoretical foundation developed to be used in tests of new information technology, Technology Acceptance Model, students' perceptions of e-books is mapped. Important variables are perceived usefulness and perceived ease of use which influence the attitude, the intention to use and actual use.   The thesis concluded that students accept e-books as a supplement to printed books. The factor students’ value as most important is availability and that it is easy to find. The main goal of students' reading is to gain access to required literature of the course and perceived usefulness of e-books is primarily to its being available which affects studying and learning.

No / This study presents a cross-national examination of e-government adoption in the United Kingdom and the United States. The results of partial least squares analysis indicate that disposition to trust is positively related to internet trust and government trust. Perceived ease of use and perceived usefulness have a significant impact on intention to use. Internet trust has a positive effect on intention to use. We conclude by highlighting cultural differences in e-government adoption.

Several models have been developed for understanding and predicting innovation adoption in organizations and literature has identified several factors that impact the adoption and implementation of Information Technology (IT). This research examines the process of adoption of IT innovations in organizations. The study explores the processes involved in the adoption of IT and verifies the key factors that influence IT innovation adoption in organizations. Using a systematic literature review, the study developed a conceptual model of IT innovation adoption in organizations. The model is a theoretical combination of Diffusion of Innovation (DOI) theory, Theory of Reasoned Action (TRA), Technology Acceptance Model (TAM), Theory of Planned Behaviour (TPB) and a framework which contains characteristics of innovation, organization, environment, chief executive officer (CEO) and user acceptance. The model represents IT innovation adoption as a stage-based process, progressing from initiation to adoption-decision to implementation. The study aggregated findings of past research on IT adoption to identify key factors that influences IT adoption in organizations. The study performed a meta-analysis of innovation, organization, environment, CEOs and user acceptance determinants to assess the magnitude and the strength of these factors on IT innovation adoption. Results confirmed that relative advantage, compatibility, cost, observability and trialability are strong determinants of IT innovation adoption. In terms of organizational context, IS department size, top management support, organizational size, IT expertise, product champion, IS infrastructure, information intensity, resources and specialization was found influential in the adoption of IT. As for environmental characteristics, the meta-analysis verified the significance of external pressure, government support and competitive pressure. Meta-analysis results verified that CEO‟s innovativeness, attitude and IT knowledge as key determinants. The findings confirmed the importance of perceived usefulness, perceived ease of use, subjective norm and facilitating conditions for the user acceptance of IT in organizations.

During an emergency, information availability is critical to preserving life and minimizing damages. During the emergency response, however, information may not be available to those who need it. A community response grid (CRG) can help ameliorate this lack of availability by allowing people to document and distribute emergency information to professional emergency responders (PERs). A CRG combines mobile communications services, Internet technologies, e-government applications, and social network concepts with traditional emergency response systems. The problem that this case study investigated was how to construct a CRG for the City of Dublin, Ohio, Division of Police that works in conjunction with an in-place emergency management system (EMS). The goal was to create a process that is replicable by similarly sized cities that wished to implement a CRG. In this investigation, the author examined CRG design and implementation issues such as message origin, training needs, policy design, security issues, and funding. The results of this investigation were organized in terms of Systems Development Lifecycle (SDLC) phases. Throughout these phases, the author identified information that can aid PERs in to better implement a CRG. Based on the results, the author developed a paradigm for constructing a CRG that meets the requirements of residents of the City of Dublin, Ohio, Division of Police and of similarly sized municipalities.

Background: The market of mHealth has been growing steadily over last years, but in China, the market is not very mature, and the low level of popularity negative impact on the development. But it should be noted that the market has great potential with positive development background, the policy support by government, the widely used of smartphone and the Internet and especially the huge demand of mHealth in China.   Purpose: The purpose of the study was to reveals Chinese mHealth industry, to measure and understand the relationship between different factors that influencing the acceptance of mHealth apps in the case of Chinese users.   Method: This study was based on the UTAUT2 Model and a quantitative methodology was followed. The author excluded price value and habit from the original UTAUT and added privacy and security factor. A primary data collection was conducted through a questionnaire in this research. Suitable respondents were those individuals who needed healthcare services, and due to the budget and time limitation, a convenience sampling technique was used.   Conclusion:       The findings show that social influence makes the strongest contribution to explaining users’ acceptance of mHealth app in China. The whole ranking of the factors (from strong to weak) is social influence &gt; privacy and security &gt; facilitating condition &gt; performance expectancy. And except privacy and security, other factors are all positively affect the acceptance of Chinese mHealth app users. Organisations can use these findings to improve the design of mHealth apps in the future.
