摘要：Retrieving information from heterogeneous database systems involves a complex process and remains a challenging research area. We propose a cognitively guided approach for developing an information-retrieval agent that takes the user's information request, identifies relevant information sources, and generates a multidatabase access plan. Our work is distinctive in that the agent design is based on an empirical study of how human experts retrieve information from multiple, heterogeneous databa...

摘要：Alignment between business strategy and IS strategy is widely believed to improve business performance. This paper examines the impact of alignment on perceived business performance using Miles and Snow's popular classification of Defender, Analyzer, and Prospector business strategies. A priori theoretical profiles for these business strategies are developed using Venkatraman's (1989a) measure of business strategy. Theoretical profiles for IS strategies are developed in terms of four types of ...

摘要：As organizations implement more and more distributed work arrangements such as telecommuting, there is a need to understand the determinants of success of this new work setting. This research investigated three variables believed to impact outcomes in telecommuting: the availability of information system technology, the availability of communication technologies, and the communication patterns of telecommuters within their work groups. Two perspectives are used in this study. The direct effect...

摘要：The field of information systems is premised on the centrality of information technology in everyday socio-economic life. Yet, drawing on a review of the full set of articles published in Information Systems Research (ISR) over the past ten years, we argue that the field has not deeply engaged its core subject matter-the information technology (IT) artifact. Instead, we find that IS researchers tend to give central theoretical significance to the context (within which some usually unspecified ...

摘要：An agency framework is used to model the behavior of software developers as they weigh concerns about product quality against concerns about missing individual task deadlines. Developers who care about quality but fear the career impact of missed deadlines may take shortcuts. Managers sometimes attempt to reduce this risk via their deadline-setting policies; a common method involves adding slack to best estimates when setting deadlines to partially alleviate the time pressures believed to enco...

摘要：The conduct of net-enabled business, known variously as electronic commerce (EC) or e-Business, has changed the landscape and opportunities for IS research by shifting the focus from internal to customer/partnering systems. The article examines the two primary dyadic net-enabled relationships in the marketplace: B2C and B2B. It also considers issues that extend beyond these two relationships. B2C practice and research are analyzed from: (1) consumer, (2) service, and (3) risk perspectives. Thr...

摘要：As demand for online network services continues to grow, service providers are looking to meet this need and avail themselves of business opportunities. However, despite strong growth in demand, providers continue to have difficulty achieving profitability, customer churn remains high, and network performance continues to draw complaints. We suggest that strategic business planning for network services would benefit from a systems thinking approach that analyzes the feedback effects present in...

摘要：The cost of enhancing software applications to accommodate new and evolving user requirements is significant. Many enhancement cost-reduction initiatives have focused on increasing software structure in applications. However, while software structure can decrease enhancement effort by localizing data processing, increased effort is also required to comprehend structure. Thus, it is not clear whether high levels of software structure are economically efficient in all situations. In this study, ...

摘要：Organizations today face great pressure to maximize the benefits from their investments in information technology (IT). They are challenged not just to use IT, but to use it as effectively as possible. Understanding how to assess the competence of users is critical in maximizing the effectiveness of IT use. Yet the user competence construct is largely absent from prominent technology acceptance and fit models, poorly conceptualized, and inconsistently measured. We begin by presenting a concept...

摘要：First impression bias refers to a limitation of human information processing in which people are strongly influenced by the first piece of information that they are exposed to, and that they are biased in evaluating subsequent information in the direction of the initial influence. The psychology literature has portrayed first impression bias as a virtually inherent human bias. Drawing from multimedia literature, this study identifies several characteristics of multimedia presentations that hav...
