摘要:The majority of the reported research and development efforts on automated techniques and tools for conceptual database design have focused on design from first principles. Very few have used case-based reasoning, where cases of conceptual design are stored, indexed, and used for future designs. Furthermore, there is a general lack of reported research on validating and verifying such systems. In this paper, we describe our approach in using case-based reasoning for conceptual database design....

摘要:This paper conducts a two-period dynamic analysis of sourcing mode choices for e-commerce projects implemented by large firms during 1999-2002. We differentiate e-commerce assets that are the focus of a sourcing decision in terms of whether they are in the growth or maturity stages. We also consider hybrid governance mechanisms, such as minority equity arrangements, as a potential sourcing mode in addition to the conventional distinction between insourcing (i.e., hierarchical governance) and o...

摘要:The widespread use of information technology (IT) to create electronic linkages among supply chain partners with the objective of reducing transaction costs may have unintended adverse effects on supply chain flexibility. Increasing business dynamics, changing customer preferences, and disruptive technological shifts pose the need for two kinds of flexibility that interenterprise information systems must address-the ability of interenterprise linkages to support changes in offering characteris...

摘要:The development of electronic commerce has been constrained by the, inability of online consumers to feel, touch, and sample products through Web interfaces, as they are able to do in conventional in-store shopping. Previous academic studies have argued that this limitation could be partly alleviated by providing consumers with virtual product experience (VPE), to enable potential customers to experience products virtually. This paper discusses virtual control, a specific type of VPE implement...

摘要:Virtual teams cut across national, organizational, and functional boundaries, often resulting in diversity in team composition. This paper presents the results of a laboratory study involving groupware-supported, culturally homogeneous, and heterogeneous virtual teams where collaborative conflict management style, a team's cultural orientation as measured by the degree of individualism-collectivism, and group diversity affect several group performance variables. Collaborative conflict manageme...

摘要:A feature central to the success of e-commerce Web sites is the design of an effective interface to present product information. However, the suitability of the prevalent information formats in supporting various online shopping tasks is not known. Using the cognitive fit theory as the theoretical framework, we developed a research model to investigate the fit between information format and shopping task, and examine its influence on consumers' online shopping performance and perceptions of sh...

摘要:Creating electronic communities is a critical venture in the digital economy. However, fraud and misrepresentation have led to widespread skepticism and distrust of electronic communities. We develop an evolutionary model to explore the issue of trust within an electronic community from a dynamic process perspective. This model emphasizes large populations, continuous change in community memberships, and imperfect information and memory. As the term trust is often used in the context of indivi...

摘要:This study investigates the effect of varying project complexity on the group interaction processes of small information technology (IT) project teams. The projects included two complex tasks (i.e., LAN and WAN development tasks) and a less complex development task (i.e., a small business Web site development task). The study found that project complexity can affect the group interaction process. Participants reported significantly higher expectations, group integration, communication, and par...

摘要:In this study, we conduct an empirical analysis of the performance of five popular data mining methods-neural networks, logistic rearession, linear discriminant analysis, decision trees, and nearest neighbor-on two binary classification problems from the credit evaluation domain. Whereas most studies comparing data mining methods have employed accuracy as a performance measure, we argue that, for problems such as credit evaluation, the focus should be on minimizing misclassification cost. We f...
