摘要：The Internet is making a significant transition from primarily a network of desktop computers to a network variety of connected information devices such as personal digital assistants and global positioning system-based devices. On the other hand, new paradigms such as overlay networks are defining service-based logical architecture for the network services that make locating content and routing more efficient. Along with Internet2's proposed service-based routing, overlay networks will create...

摘要：Two important gaps exist in the information systems (IS) alignment research. First, there is scant research on the potential of organizational culture, and specifically subcultures to influence the strategic alignment of IS and organizations. Second, there is a dearth of literature that considers the relationship between alignment and implementation success. In this paper, we address both of these gaps by considering the influence of organizational subcultures on the alignment of a specific IS...

摘要：This study extends existing information technology (IT) productivity research by evaluating the contributions of spending in IT outsourcing using a production function framework and an economywide panel data set from 60 industries in the United States over the period from 1998 to 2006. Our results demonstrate that IT outsourcing has made a positive and economically meaningful contribution to industry output and labor productivity. It has not only helped industries produce more output, but it h...

摘要：This study develops and tests the idea that the cross-business information technology integration (CBITI) capability of an acquirer creates significant value for shareholders of the acquirer in mergers and acquisitions (M&A). In M&A, integrating the IT systems and IT management processes of acquirer and target could generate benefits such as (a) the consolidation of IT resources and the reduction of overall IT costs of the combined firm, (b) the development of an IT-based coordination mechanis...

摘要：Extant research considers the IT governance choice to be a trade-off between the cost-efficiency of centralization and the responsiveness provided by local information processing. This view predicts that firms tend to decentralize IT governance in more uncertain environments. We investigate this issue by studying the relationship between environmental uncertainty and IT infrastructure governance in a sample of business units from Fortune 1000 companies. The key proposition in this paper is tha...

摘要：Combinatorial auctions are used for the efficient allocation of heterogeneous goods and services. They require appropriate software platforms that provide automated winner determination and decision support for bidders. Several promising ascending combinatorial auction formats have been developed throughout the past few years based on primal-dual algorithms and linear programming theory. The ascending proxy auction and iBundle result in Vickrey payoffs when the coalitional value function satis...

摘要：Firms need to balance efficiency gains obtained through exploiting existing knowledge assets with long-term competitive viability achieved through exploring new knowledge resources. Because the use of knowledge management systems (KMSs) continues to expand, understanding how these systems affect exploration and exploitation practices at the individual level is important to advance both knowledge management theory and practice. This study reports the results of a multi-industry survey investiga...

摘要：To improve operational efficiencies while providing state of the art healthcare services, hospitals rely on information technology enabled physician referral systems (IT-PRS). This study examines learning curves in an IT-PRS setting to determine whether agents achieve performance improvements from cumulative experience at different rates and how information technologies transform the learning dynamics in this setting. We present a hierarchical Bayes model that accounts for different agent skil...

摘要：Although many organizations are implementing knowledge management systems (KMS), there is little empirical evidence about whether KMS use can improve individual performance, and how time and experience influence the value derived from KMS use. Using hierarchical linear modeling (HLM) statistical analysis, we examined the impact of using a codification-based KMS on the sales performance of 2,154 sales representatives in a pharmaceutical firm over a 24-month period. We found that KMS had signifi...

摘要：We use panel data from multiple wards from two hospitals spanning a three-year period to investigate the impact of automation of the core error prevention functions in hospitals on medical error rates. Although there are studies based on anecdotal evidence and self-reported data on how automation impacts medical errors, no systematic studies exist that are based on actual error rates from hospitals. Further, there is no systematic evidence on how incremental automation over time and across mul...
