摘要：In many domains of increased turbulence and volatility, interorganizational ad hoc collaborations are common. One such domain is homeland security in which security professionals collaborate virtually with individuals outside of their own organizations in response to a security threat. In such a domain, a safe context is needed to ensure that interactions with collaborators not only help to solve the immediate threat but also avoid the improper use by outside parties of information released du...

摘要：The increasing importance of information technology (IT) services in the global economy prompts researchers in the field of information systems (IS) to give special attention to the foundations of managerial and technical knowledge in this emerging arena of knowledge. Already we have seen the computer science discipline embrace the challenges of finding new directions in design science toward making services-oriented computing approaches more effective, setting the stage for the development of...

摘要：Follow the sun (FTS) has interesting appeal-hand off work at the end of every day from one site to the next, many time zones away, in order to speed up product development. Although the potential effect on time to market can be profound, at least conceptually, FTS has enjoyed few documented industry successes because it is acknowledged to be extremely difficult to implement. In order to address this FTS challenge, we provide here a conceptual foundation and formal definition of FTS. We then an...

摘要：Opportunism, or self-interest seeking with guile, is often witnessed in human behavior, and it bedevils human interactions and relationships. Organizations expend considerable effort to reduce opportunism. Agency theory espouses formal contracts as effective constraints on opportunism; however, a consultant's use of tacit knowledge subjects clients to information asymmetry that is not amenable to formal contracts. The principal professional lens was developed to accommodate the presence of tac...

摘要：In this paper, we set up a game-theoretic model to examine oligopolistic price competition, considering two features of online search: the existence of a common search ordering and shoppers who have nonpositive search cost. We find that in equilibrium firms set their prices probabilistically rather than deterministically, and different firms follow different price distributions. The equilibrium pricing pattern exhibits an interesting local-competition feature in which direct price competition ...

摘要：Phishing has been a major problem for information systems managers and users for several years now. In 2008, it was estimated that phishing resulted in close to $50 billion in damages to U.S. consumers and businesses. Even so, research has yet to explore many of the reasons why Internet users continue to be exploited. The goal of this paper is to better understand the behavioral factors that may increase one's susceptibility for complying with a phisher's request for personal information. Usin...

摘要：Over the past few years, open source software (OSS) development has gained a huge popularity and has attracted a large variety of developers. According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. W...

摘要：Online retailers are increasingly using information technologies to provide value-added services to customers. Prominent examples of these services are online recommender systems and consumer feedback mechanisms, both of which serve to reduce consumer search costs and uncertainty associated with the purchase of unfamiliar products. The central question we address is how recommender systems affect sales. We take into consideration the interaction among recommendations, sales, and price. We then...

摘要：Service-oriented architecture (SOA) is one of the most discussed topics in the information systems (IS) discipline. While most computer scientists agree that the service-oriented paradigm has clear benefits in terms of technical quality attributes, it has been difficult to justify SOA economically. The few studies that have investigated the strategic and economic aspects of SOA are mostly exploratory and lack a more comprehensive framework for understanding the sources of its economic potentia...
