摘要：Information security investment has been getting increasing attention in recent years. Various methods have been proposed to determine the effective level of security investment. However, traditional expected value methods (such as annual loss expectancy) cannot fully characterize the information security risk confronted by organizations, considering some extremal yet perhaps relatively rare cases in which a security failure may be critical and cause high losses. In this research note we intro...

摘要：Information systems (IS) researchers have typically examined the user-system relationship as an isolated dyad between a single, independent user and an individual, freestanding information system. We argue that this conceptualization does not adequately represent most organizations today, in which multiple users interact with multiple information systems within a group. Relying heavily on the theory and methods behind social network analysis, we introduce the concept of multimodal networks to ...

摘要：Online product reviews may be subject to self-selection biases that impact consumer purchase behavior, online ratings' time series, and consumer surplus. This occurs if early buyers hold different preferences than do later consumers about the quality of a given product. Readers of early product reviews may not successfully correct for these preference differences when interpreting ratings and making purchases. In this study, we develop a model that examines how idiosyncratic preferences of ear...

摘要：With the continued growth of business-to-consumer (B2C) e-business, online vendors are providing an increasing array of services that support and enhance their core products or services. For example, Amazon.com does not just sell books; it also enhances that core product with automated product recommendations, wish list tracking, order status updates, customer reviews, and many other valuable supporting services. These supporting services are made possible exclusively through the design and de...

摘要：Peer production phenomena such as open source software (OSS) have been posited as a viable alternative to traditional production models. However, community-based development often falls short of creating software products in the sense that consumers understand. Our research identifies an emerging business network archetype in the OSS sector, the open source service network (OSSN), which seeks to address the productization challenge. To do so, OSSNs must overcome the problems associated with ex...

摘要：The capabilities offered by digital communication are leading to the evolution of new network structures that are grounded in communication patterns. As these structures are significant for organizations, much research has been devoted to understanding network dynamics in ongoing processes of electronic communication. A valuable method for this objective is Social Network Analysis. However, its current focus on quantifying and interpreting aggregated static relationship structures suffers from...

摘要：The five-factor model (FFM) of personality has been used to great effect in management and psychology research to predict attitudes, cognitions, and behaviors, but has largely been ignored in the IS field. We demonstrate the potential utility of incorporating this model into IS research by using the FFM personality factors in the context of technology acceptance. We propose a dispositional perspective to understanding user attitudes and beliefs, and examine the effect of user personality-captu...

摘要：This paper explores a new phenomenon at the intersection of digital networks and organizations-the Internet-based volunteer work force-people who use Internet applications to pursue a personal interest through volunteering contributions of time and talent that may create value for organizations and their customers or members. This work force is not centrally organized, managed, or measured. It is an emergent phenomenon resulting from discretionary small actions taken by large numbers of people...

摘要：This study compares the performances of pair development (an approach in which a pair of developers jointly work on the same piece of code), solo development, and mixed development under two separate objectives: effort minimization and time minimization. To this end, we develop analytical models to optimize module-developer assignments in each of these approaches. These models are shown to be strongly NP-hard and solved using a genetic algorithm. The solo and pair development approaches are co...

摘要：A major impediment to accurate information retrieval from the World Wide Web is the inability of search engines to incorporate semantics in the search process. This research presents a methodology, CONQUER (CONtext-aware QUERy processing), that enhances the semantic content of Web queries using two complementary knowledge sources: lexicons and ontologies. The methodology constructs a semantic net using the original query as a seed, and refines the net with terms from the two knowledge sources....
