This paper presents an extension to the technology acceptance model (TAM) and empirically examines it in an enterprise resource planning (ERP) implementation environment. The study evaluated the impact of one belief construct (shared beliefs in the benefits of a technology) and two widely recognized technology implementation success factors (training and communication) on the perceived usefulness and perceived ease of use during technology implementation. Shared beliefs refer to the beliefs that organizational participants share with their peers and superiors on the benefits of the ERP system. Using data gathered from the implementation of an ERP system, we showed that both training and project communication influence the shared beliefs that users form about the benefits of the technology and that the shared beliefs influence the perceived usefulness and ease of use of the technology. Thus, we provided empirical and theoretical support for the use of managerial interventions, such as training and communication, to influence the acceptance of technology, since perceived usefulness and ease of use contribute to behavioral intention to use the technology. # 2003 Elsevier B.V.

One often meets the argument that the adoption of mobile Internet services is difficult to understand due to a lack of relevant research. However, much research has already been conducted on the adoption of basic mobile and traditional Internet services that are likely to converge into the services provided by the mobile Internet. In this article, we try to categorize four research directions relevant in understanding mobile Internet service adoption. We argue that because mobile Internet services are new, a lack of studies directly investigating the adoption these services is to be expected. However, we also argue that existing research directions provide valuable points of departure for further investigating and understanding the adoption of mobile Internet services. In particular, we suggest a cross disciplinary integration of the findings of four different research directions may improve our understanding of the basic mechanisms of individuals' adoption of mobile Internet services. In this article, we exemplify such an integration by suggesting how traditional adoption models in information systems research, such as the technology acceptance model or the theory of planned behavior, may be modified and extended when applied to study the adoption of mobile Internet services. 1.

Flow theory has been borrowed from psychology to address positive user experiences with personal computers, and more recently, the Internet. The flow experience has been correlated to increased exploratory behavior, communication, learning, positive affect, and computer use. This paper reviews the flow studies within computer-mediated environments to gain a more coherent understanding. The authors identify ambiguities in the conceptualization of flow, challenges in the operationalization of flow constructs, and difficulties in data collection.

Research in computer-mediated communication has usually emphasized the cognitive over the social aspects of communication, the medium over the message, and the product of communication over the process. In contrast, this paper emphasizes three constructs of the communication process: goal-based communication strategies, message form, and medium. We seek to balance cognitive and social communication strategies and to combine new and old measures of the message form (organization, formality, and size). A field study in an academic institution examines the content of text-based communication delivered by letter, memo, fax, and email. As expected, people prefer certain message and medium attributes for certain strategies. These findings are further investigated using open-ended interviews. We conclude with examples of practical implications on designing and implementing computer-mediated communication.

Text messaging in the form of SMS has become one of the most successful mobile services in Europe, and the use of this service is now well integrated into the everyday life of young Europeans. To explain the widespread adoption of this service, findings from diffusion, uses and gratifications, information systems and domestication research are reviewed and integrated into a re-specified and extended model based upon the theory of planned behavior. The model is tested on a sample of young users of text messaging services. We conclude that the suggested respecifications and extensions are justified. The final model shows good fit and explains 74% of the variance in intention to use text messaging services. The results support including elements of enjoyment and expressiveness in models of text messaging adoption, show little support for including subjective norm, and indicate that users may perceive some form of deficient selfregulation in the use of these services. The results also show interesting differences between the adoption models of male and female users. 1.

Flow theory has been applied to computer-mediated environments to study positive user experiences such as increased exploratory behavior, communication, learning, positive affect, and computer use. However, a review of the existing flow studies in computer-mediated environments in Psychology, Consumer Behavior, Communications, Human-Computer Interaction, and Management Information Systems shows ambiguities in the conceptualization of flow constructs and inconsistency in the flow models. It thus raises the question of whether the direct adoption of traditional flow theory is appropriate without a careful re-conceptualization to consider the uniqueness of the computer-mediated environments. This paper focuses on flow antecedents and identifies the importance of separating the task from the artifact within a computer-mediated environment. It proposes a component-based model that consists of person (P), artifact (A), and task (T), as well as the interactions of these components. The model, named the PAT model, is developed by understanding the original flow theory, reviewing existing empirical flow studies within computer-mediated environments, and analyzing the characteristics of computer-mediated environments. A set of propositions is constructed to demonstrate the predictive power of the model. Keywords: flow theory, flow antecedents, computer-mediated environment (CME), perceived ease of use (PEOU), computer playfulness, Person Artifact Task (PAT) model, affect 1 1.

Modern theories of human evolution converge on the belief that our brain has been designed to cope with problems that occurred intermittently in our evolutionary past. Evidence suggests that, during over 99 percent of the evolutionary process leading to the emergence of our species, our ancestors communicated in a synchronous and colocated manner, and employing facial expressions, body language, and oral speech (what we refer to here, generally, as “face-to-face ” communication). Thus, it is plausible to assume that many of the evolutionary adaptations our brain has undergone in connection with communication have been directed at improving the efficiency and effectiveness of face-to-face communication, which begs the question: What happens when we selectively suppress face-to-face communication elements (e.g., colocation, the ability to employ/observe facial expressions) through e-communication technologies? This paper tries to provide an answer to this question by developing a hypothesis, called the media naturalness hypothesis, which builds on modern human evolution theory. The media naturalness hypothesis argues that, other things being equal, a decrease in the degree of naturalness of a communication medium (or its degree of similarity to the face-to-face medium) leads to the following effects in connection with a communication interaction: (1) increased cognitive effort, (2) increased communication ambiguity, and (3) decreased physiological arousal. It is argued that the media naturalness hypothesis has important implications for the selection, use, and deployment of e-communication tools in organizations, particularly in the context of business-to-consumer interactions.
