摘要：Application service providers (ASP), who host and maintain information technology (IT) applications across the Internet, emerged as an innovation in the way IT services are delivered to client firms. In spite of many potential benefits of this model, ASPs experienced business failure and high rates of exit. Drawing on agency theory, we argue that the efficiency of contracting arrangements between ASPs and client organizations is an important determinant of ASP survival. We test this prediction...

摘要：We investigate the incentive issues that surround the adoption and sharing of electronic health records (EHR) and the potential role of a personal health record (PHR) platform in facilitating data sharing. Through our analysis, we find evidence that health-care providers may not have an incentive to share patients' records electronically even though EHR systems will increase consumer surplus, especially in the presence of provider heterogeneity and myopic consumers. In this context, we find th...

摘要：Despite much hype about electronic payments systems (EPSs), a 2004 survey establishes that close to 80% of between-business payments are still made using paper-based formats. We present a finite mixture logit model to predict likelihood of EPS adoption in business-to-business (B2B) settings. Our model simultaneously classifies firms into homogeneous segments based on firm-specific characteristics and estimates the model's coefficients relating predictor variables to EPS adoption decisions for ...

摘要：Web personalization allows online merchants to customize Web content to serve the needs of individual customers. Using data mining and clickstream analysis techniques, merchants can now adapt website content in real time to capture the current preferences of online customers. Though the ability to offer adaptive content in real time opens up new business opportunities for online merchants, it also raises questions of timing. One question is when to present personalized content to consumers. Co...

摘要：In this paper we examine the use of electronic patient records (EPR) by clinical specialists in their development of multidisciplinary care for diagnosis and treatment of breast cancer. We develop a practice theory lens to investigate EPR use across multidisciplinary team practice. Our findings suggest that there are oppositional tendencies towards diversity in EPR use and unity which emerges across multidisciplinary work, and this influences the outcomes of EPR use. The value of this perspect...

摘要：Historically, the use of peer-to-peer (P2P) networks has been limited primarily to user-initiated exchanges of (mostly music) files over the Internet. This traditional view of P2P networks is changing, however, and the use of P2P networks has been suggested for delivering general-purpose content over the Web (or corporate intranets), even in real time. We analyze sharing in a P2P community in this new context under three different congestion measures: delay, jitter, and packet loss. Sharing is...

摘要：Online discussion communities have become a widely used medium for interaction, enabling conversations across a broad range of topics and contexts. Their success, however, depends on participants' willingness to invest their time and attention in the absence of formal role and control structures. Why, then, would individuals choose to return repeatedly to a particular community and engage in the various behaviors that are necessary to keep conversation within the community going? Some studies ...

摘要：The digital divide has loomed as a public policy issue for over a decade. Yet, a theoretical account for the effects of the digital divide is currently lacking. This study examines three levels of the digital divide. The digital access divide (the first-level digital divide) is the inequality of access to information technology (IT) in homes and schools. The digital capability divide (the second-level digital divide) is the inequality of the capability to exploit IT arising from the first-leve...

摘要：Despite the significant potential for performance gains from health IT (HIT), there has been limited study of the mechanisms underlying successful HIT implementations. We conducted an extensive longitudinal field study to gain an understanding of the interplay between technology and patterns of clinical work embodied in routines. We use the analytical device of narrative networks to identify where and how HIT influences patterns of work. We further draw upon adaptive structuration theory to co...

摘要：The electronic gulf between shoppers and products makes evaluating a physical product on offer at an e-store a potentially problematic activity. We propose that the outcome of the product evaluation task is determined by the fit between the type of information provided and the type of information sought by the consumer and that this, in turn, influences a consumer's attitude toward an e-store. An experiment to compare the impact of one type of advanced evaluation support technology, the virtua...
