摘要：This issue marks the end of the third and last year of my term as Editor-in-Chief of ISR. Three years ago wrote an editorial for the first issue that set the tone and immediate goals for the journal, summarized as follows: ISR has established itself as one of a small set of top-tier academic journals in the information systems discipline. Editorial policy changes have been designed to strengthen a number of aspects of the journal, particularly the Timeliness of the work published, without havi...

摘要：T he proliferation of information on the Internet poses a significant challenge on humans' limited attentional resources. To attract online users' attention, various kinds of animation are widely used on websites. Despite the ubiquitous use of animation, there is an inadequate understanding of its effect on attention. Focusing on flash animation, this study examines its effects on online users' performance and perceptions in both task-relevant and task-irrelevant information search contexts by...

摘要：W e study the process by which model-based decision support systems (DSSs) influence managerial decision making in the context of marketing budgeting and resource allocation. We focus on identifying whether and how DSSs influence the decision process (e.g., cognitive effort deployed, discussion quality; and decision alternatives considered) and, as a result, how these DSSs influence decision outcomes (e.g., profit and satisfaction both with the decision process and the outcome). We study two s...

摘要：We use an economic model to formalize the complex relationships among IT investments, intermediate performance measures (e.g., product quality and output levels), and economic performance (e.g., productivity, profits, and consumer surplus). We demonstrate that a profit-maximizing monopolist invests in IT (modeled as changes in parametric characteristics of the firm) to design a better-quality product and charge a higher price. While this profit-maximizing adjustment generates more consumer sur...

摘要：In this paper we address the problem of increasing software maintenance costs in a custom software development environment, and develop a stochastic decision model for the maintenance of information systems. Based on this modeling framework, we derive an optimal decision rule for software systems maintenance, and present sensitivity analysis of the optimal policy. We illustrate an application of this model to a large telecommunications switching software system, and present sensitivity analysi...

摘要：The lack of consumer confidence in information privacy has been identified as a major problem hampering the growth of e-commerce. Despite the importance of understanding the nature of online consumers' concerns for information privacy, this topic has received little attention in the information systems community. To fill the gap in the literature, this article focuses on three distinct, yet closely related, issues. First, drawing on social contract theory, we offer a theoretical framework on t...

摘要：The decision processes surrounding investments in innovative information technology (IT) platforms are complicated by uncertainty about expected payoffs and irreversibilities in the costs of implementation. When uncertainty and irreversibility are high, concepts from real options should be used to properly structure the evaluation and management of investment opportunities, and thereby capture the value of managerial flexibility. However, while innovation researchers have posited that option v...

摘要：Focus on individual outsourcing decisions in IT research has often yielded contradictory findings and recommendations. To address these contradictions, we investigate a holistic, configurational approach with the prevailing universalistic or contingency perspectives in exploring the effects of IT outsourcing strategies on outsourcing success. Based on residual rights theory, we begin by identifying three dimensions of IT outsourcing strategies: degree of integration, allocation of control, and...

摘要：Information technology (IT) outsourcing success requires careful management of customer-supplier relationships. However, there are few published studies on the ongoing relationships, and most of these adopt a customer perspective, de-emphasizing suppliers. In this study, we look at both customer and supplier perspectives, by means of the psychological contract of customer and supplier project managers. We apply the concept of psychological contract to perceived mutual obligations, and to how s...

摘要：Institution-based trust is a buyer's perception that effective third-party institutional mechanisms are in place to facilitate transaction success. This paper integrates sociological and economic theories about institution-based trust to propose that the perceived effectiveness of three IT-enabled institutional mechanisms-specifically feedback mechanisms, third-party escrow services, and credit card guarantees-engender buyer trust in the community of online auction sellers. Trust in the market...
