摘要：Web search engines have become an integral part of the daily life of a knowledge worker, who depends on these search engines to retrieve relevant information from the Web or from the company's vast document databases. Current search engines are very fast in terms of their response time to a user query. But their usefulness to the user in terms of retrieval performance leaves a lot to be desired. Typically, the user has to sift through a lot of nonrelevant documents to get only a few relevant o...

摘要：Understanding the successful adoption of information technology is largely based upon understanding the linkages among quality, Satisfaction, and usage. Although the satisfaction and usage constructs have been well studied in the information systems literature, there has been only limited attention to information and system quality over the past decade. To address this shortcoming, we developed a model consisting of nine fundamental determinants of quality in an information technology contexts...

摘要：This paper uses modified economic growth theory to compare and contrast two currently available ways of digital content distribution: the client-server model and the peer-to-peer (P2P) model. We describe a monopolistic pricing scheme for distributing digital content over P2P networks that rewards peer users who actively participate in the distribution process. Our results show that digital distribution through a P2P network is more profitable and more efficient than in the corresponding client...

摘要：The capabilities of network technologies have facilitated the growth of electronic commerce. Major issues-notably, security and product quality uncertainty-still pose serious challenges to the further adoption of electronic commerce. Traditional market transactions have a long history and well-understood protections for buyers and sellers. In the electronic markets, formal and informal mechanisms such as trusted third parties (TTP) have emerged trying to ensure safe transactions. In this paper...

摘要：The technology acceptance model (TAM) is one of the most widely used models of information technology (IT) adoption. According to TAM, IT adoption is influenced by two perceptions: usefulness and ease of use. In this study, we extend TAM to the mobile commerce context. We categorize the tasks performed on wireless handheld devices into three categories: (1) general tasks that do not involve transactions and gaming, (2) gaming tasks, and (3) transactional tasks. We propose a unified conceptual ...

摘要：Trust provides the foundation for the successful implementation and operation of a virtual community (VC). Trust is an especially relevant success factor in online health-care communities. A look at existing communities leads to the conclusion that many VCs fail to meet requirements upon which trust is established. Based on the findings in the literature and the researchers' experience, this paper describes how trust-enabling functionalities can be systematically designed and implemented in a ...

摘要：This paper reports the results of an experiment investigating the differences between budget negotiations conducted on an electronic negotiation support system (NSS) and those conducted face-to-face. The negotiation setting consisted of a supervisor and a subordinate negotiating a performance budget for the subordinate. Results revealed that when supervisor performance expectations were incongruent with subordinate capability, face-to-face negotiations hit impasse at a significantly higher rat...

摘要：The basic premise of the extant literature related to electronic integration has been that the higher the integration, the higher will be the organizational performance. However, excessive electronic integration can be dysfunctional too. We make a conceptual argument that more is not always better and that the fit between contextual factors and electronic information sharing should be achieved to seek optimal channel performance. We empirically examine the fit between electronic information tr...

摘要：Although there has been a great deal of research on impression formation, little application of that research has been made to electronic commerce. A research model was constructed that hypothesized errors, poor style, and incompleteness to be inversely related to the users' level of perceived quality of an online store. Further, this perceived quality of the online store's Web site would be directly related to users' trust in the store and, ultimately, to users' intentions to purchase from th...

摘要：This study uses Galbraith's information processing theory to examine the fit between information processing needs and information processing capability in an interorganizational supply chain context and to examine its effect on performance. Information processing needs are assessed based on various characteristics of the product and procurement environment and information processing capabilities are assessed by the level of information technology support for various activities in the procureme...
