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....

摘要：The growth of the Internet has spawned an increasing number of online information sources (OISs). The effect of OISs on consumer information search processes has been particularly striking in sectors such as auto retailing, where the typical consumer has conventionally been confronted with an unpleasant and inefficient purchase process. However, the relationships between the information found in the online marketspace, consumer search in the offline marketplace, and other aspects of the multic...

摘要：To understand the impact of social capital on knowledge integration and performance within digitally enabled teams, we studied 46 teams who had a history and a future working together. All three dimensions of their social capital (structural, relational, and cognitive) were measured prior to the team performing two tasks in a controlled setting, one face-to-face and the other through a lean digital network. Structural and cognitive capital were more important to knowledge integration when team...

摘要：Prior research has indicated that, on average, offshore vendors have higher profits associated with time and materials (T&M) contracts than fixed price (FP) contracts. This research raises two questions. First, Is the relative importance of various profit drivers different across two contractual regimes? Second, Does it follow that vendors unconditionally prefer T&M contracts for all projects? We address these questions by using data on 93 offshore projects completed by a leading Indian vendor...

摘要：We study the question of whether a software vendor should allow users of unlicensed (pirated) copies of a software product to apply security patches. We present a joint model of network software security and software piracy and contrast two policies that a software vendor can enforce: (i) restriction of security patches only to legitimate users or (ii) provision of access to security patches to all users whether their copies are licensed or not. We find that when the software security risk is ...

摘要：In many industries, Internet referral services, hosted either by independent third-party infomediaries or by manufacturers, serve as digitally enabled lead generators in electronic markets, directing consumer traffic to downstream retailers in a distribution network. This reshapes the extended enterprise from the traditional network of upstream manufacturers and downstream retailers to include midstream third-party and manufacturer-owned referral services in the supply chain. We model competit...
