Communicated by S. Wiedenbeck Along with increasing investments in new technologies, user technology acceptance becomes a frequently studied topic in the information systems discipline. The last two decades have seen user acceptance models being proposed, tested, refined, extended and unified. These models have contributed to our understanding of user technology acceptance factors and their relationships. Yet they have also presented two limitations: the relatively low explanatory power and inconsistent influences of the factors across studies. Several researchers have recently started to examine the potential moderating effects that may overcome these limitations. However, studies in this direction are far from being conclusive. This study attempts to provide a systematic analysis of the explanatory and situational limitations of existing technology acceptance studies. Ten moderating factors are identified and categorized into three groups: organizational factors, technological factors and individual factors. An integrative model is subsequently established, followed by corresponding propositions pertaining to the moderating factors.

Feedback is viewed as an essential element of ubiquitous computing systems in the HCI literature for helping people manage their privacy. However, the success of online social networks and existing commercial systems for mobile location sharing which do not incorporate feedback would seem to call the importance of feedback into question. We investigated this issue in the context of a mobile location sharing system. Specifically, we report on the findings of a field deployment of Locyoution, a mobile location sharing system. In our study, (n = 56), one group was given feedback in the form of a history of location requests, and a second group was given no feedback at all. Our major contribution has been to show that feedback is an important contributing factor towards improving user comfort levels and allaying privacy concerns. Participants ’ privacy concerns were reduced after using the mobile location sharing system. Additionally, our study suggests that peer opinion and technical savviness contribute most to whether or not participants thought they would continue to use a mobile location technology.

This study applies recent findings in the intrinsic motivation and computer self-efficacy research to Technology Acceptance Model in order to predict the use of web-based information systems. One hundred nine subjects participated in the study, which was conducted in a field setting with Blackboard system, a web-based class management system. A survey was administered at the beginning of the study and the actual use of the system was captured by the Blackboard system over eight weeks. The results largely support the proposed model, highlighting the important roles of perceived enjoyment, learning goal orientation, and self-efficacy in determining the actual use of the system.

To increase their revenue from electronic commerce, more and more Internet businesses are soliciting personal information from consumers so as to target products and services at the right consumers. But when deciding whether to disclose their personal information to Internet businesses, consumers may weigh the concerns of giving up information privacy against the benefits of information disclosure. This paper examines how Internet businesses can motivate consumers to disclose their personal information. Based on a synthesis of the literature, it identifies seven types of extrinsic or intrinsic benefits that Internet businesses can provide when soliciting personal information from consumers. Through comprehensive conceptual and empirical validation processes, it develops an instrument that allows Internet businesses to gauge the preference of consumers for the various types of benefits. By testing a set of nomological networks, it offers some ideas to Internet businesses about what types of benefits may be more effective given the personality traits of consumer populations. Besides providing a foundation for efforts at developing theories on information privacy and information disclosure, the results of this research provide useful suggestions to Internet businesses on how best to solicit personal information from consumers. Implications for research and practice are discussed. Key words: privacy, Internet business, information disclosure, extrinsic benefit, intrinsic benefit, personality, confirmatory factor analysis.

This study examines the use of integrated communication and engineering design tools in a distributed learning environment. We examined students' attitudes toward the technology using two different approaches. First, we utilized the technology acceptance model to investigate the attitude formation process. Then, to investigate how attitudes changed over time, we applied social information processing model using social network analysis method. Using the technology acceptance model, we were able to demonstrate that students' initial expectation affected the perceptions of, attitudes toward, and use of the system. With social network analysis, we found that one's attitude change was significantly influenced by other students' attitude changes. We discussed the uniqueness of distance learning environments in the context of social influence research and how studies of distance learning could contribute to the research on the social influence of technology use.

There is evidence to suggest that health professionals are reluctant to accept and utilise information and communication technologies (ICT) and concern is growing within health informatics research that this is contributing to the lag in adoption and utilisation of ICT across the health sector. Technology acceptance research within the field of information systems has been limited in its application to health and there is a concurrent need to develop and gain empirical support for models of technology acceptance within health and to examine acceptance and utilisation issues amongst health professionals to improve the success of information system implementation in this arena. This paper outlines a research project that will examine ICT acceptance and utilisation by Australian occupational therapists. It describes the theoretical basis behind the development of a research model and the methodology that will be employed to empirically validate the model using substantial quantitative, qualitative and longitudinal data. The theoretical significance of this work is that it uses a thoroughly constructed research model, with potentially the largest sample size ever tested, to extend technology acceptance research into the health sector. The results of this study will have practical and theoretical applications for five major stakeholder groups.

Abstract: Most existing models or theories in IS focus on the cognitive and behavioral aspects of human decision-making processes and on individual reactions to using technologies in organizations and other contexts. The influence of affect or emotion is traditionally neglected. The affective aspect, however, is considered crucial, and has gained attention in psychology, marketing, organizational behavior, and other fields. Recently, affect and related concepts have attracted attention from researchers in information systems (IS) and human-computer interaction (HCI). Yet, studies of affect have been scattered and less systematic. This paper first examines the theoretical advancement of affect studies in several referencing disciplines to IS: psychology, organizational psychology, and marketing and consumer behavior. An abstract model of the individual interacting with an object (IIO) is developed to represent the important contributors to behavior intention and behavior of people interacting with objects. Then the chapter continues with a comprehensive survey of existing studies on affect in the IS discipline to demonstrate the current status of the research stream, some conceptual discrepancies and limitations, and some potential areas for future research. An ITspecific model of IIO, a model of individual interaction with IT (IIIT), is constructed as both a framework and a theoretical model to interpret and predict individual IT user behavior. This study is an attempt to highlight and systematically analyze the influence of affect in IS and therefore has great implications for both researchers and practitioners.

Integrated with G-Portal, a Web-based geospatial digital library of geography resources, this paper describes the implementation of Mobile G-Portal, a group of mobile devices as learning assistant tools supporting collaborative sharing and learning for geography fieldwork. Based on a modified Technology Acceptance Model and a Task-Technology Fit model, an initial study with Mobile G-Portal was conducted involving 39 students in a local secondary school. The findings suggested positive indication of acceptance of Mobile G-Portal for geography fieldwork. The paper concludes with a discussion on technological challenges, recommendations for refinement of Mobile G-Portal, and design implications in general for digital libraries and personal digital assistants supporting mobile learning.
