摘要：Universal access (UA) to the Internet and the associated information infrastructure has become an important economic and societal goal. However, UA initiatives tend to focus on issues such as physical access and geographical ubiquity, and they measure adoption through penetration rates. In this paper, we apply an interpretive case study approach to analyze the Philadelphia wireless initiative to provide insights into the nature of UA and extend this concept to also consider universal use (UU)....

摘要：Topical locality on the Web is the notion that pages tend to link to other topically similar pages and that such similarity decays rapidly with link distance. This supports meaningful Web browsing and searching by information consumers. It also allows topical Web crawlers, programs that fetch pages by following hyperlinks, to harvest topical subsets of the Web for applications such as those in vertical search and business intelligence. We show that the Web exhibits another property that we cal...

摘要：This paper considers on-demand services and its impact on market structure, firm profitability, and consumer welfare. The unique properties of on-demand services are the conversion of fixed costs to variable costs, removal of capacity constraint, and fast setup time (which enables quick entry by any firm at any time when there is opportunity), whereas privacy and security concerns and switching costs have been noted as the biggest barriers from adopting on-demand services. With a stylized mode...

摘要：Interactive online decision aids often employ User-decision aid dialogues as forms of user-system interaction to help construct and elicit users' attribute preferences about a product type. This study extends prior research on online decision aids by investigating the effects of a decision aid's user-system interaction mode (USIM), which can be either user-guided or system-controlled, on users' effort-related (number of iterations of using the aid and perceived cognitive effort expended in usi...

摘要：This article investigates the economic consequences of data errors in the information flows associated with business processes. We develop a process modeling-based methodology for managing the risks associated with such data errors. Our method focuses on the topological structure of a process and takes into account its effect on error propagation and risk mitigation using both expected loss and conditional value-at-risk risk measures. Using this method, optimal strategies can be designed for c...

摘要：Information systems must be used effectively to obtain maximum benefits from them. However, despite a great deal of research on when and why systems are used, very little research has examined what effective system use involves and what drives it. To move from use to effective use requires understanding an information system's nature and purpose, which in turn requires a theory of information systems. We draw on representation theory, which states that an information system is made up of sever...

摘要：Combinatorial auctions are used in a variety of application domains, such as transportation or industrial procurement, using a variety of bidding languages and different allocation constraints. This flexibility in the bidding languages and the allocation constraints is essential in these domains but has not been considered in the theoretical literature so far. In this paper, we analyze different pricing rules for ascending combinatorial auctions that allow for such flexibility: winning levels ...

摘要：Existing research provides little insight into how social influence affects the adoption and diffusion of competing innovative artifacts and how the experiences of organizational members who have worked with particular innovations in their previous employers affect their current organizations' adoption decision. We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially inf...

摘要：We explore how Internet browsing behavior varies between mobile phones and personal computers. Smaller screen sizes on mobile phones increase the cost to the user of browsing for information. In addition, a wider range of offline locations for mobile Internet usage suggests that local activities are particularly important. Using data on user behavior at a (Twitter-like) microblogging service, we exploit exogenous variation in the ranking mechanism of posts to identify the ranking effects. We s...

摘要：Privacy is of prime importance to many individuals when they attempt to develop online social relationships. Nonetheless, it has been observed that individuals' behavior is at times inconsistent with their privacy concerns, e.g., they disclose substantial private information in synchronous online social interactions, even though they are aware of the risks involved. Drawing on the hyperpersonal framework and the privacy calculus perspective, this paper elucidates the interesting roles of priva...
