  摘要：Web site navigability refers to the degree to which a visitor can follow a Web site's hyperlink structure to successfully find information with efficiency and ease. In this study, we take a data-driven approach to measure Web site navigability using Web data readily available in organizations. Guided by information foraging and information-processing theories, we identify fundamental navigability dimensions that should be emphasized in metric development. Accordingly, we propose three data-dri...

  摘要：Despite the importance of online product recommendations (OPRs) in e-commerce transactions, there is still little understanding about how different recommendation sources affect consumers' beliefs and behavior, and whether these effects are additive, complementary, or rivals for different types of products. This study investigates the differential effects of provider recommendations (PRs) and consumer reviews (CRs) on the instrumental, affective, and trusting dimensions of consumer beliefs and...
• The Effect of an Initial Budget and Schedule Goal on Software Project Escalation AI翻译

  摘要：Software project escalation is a costly problem that leads to significant financial losses. Prior research suggests that setting a publicly announced limit on resources can make individuals less willing to escalate their commitment to a failing course of action. However, the relationship between initial budget and schedule goals and software project escalation remains unexplored. Drawing on goal setting theory as well as sunk cost and mental budgeting perspectives, we explore the effect of goa...
• Patch Release Behaviors of Software Vendors in Response to Vulnerabilities: An Empirical Analysis AI翻译
  作者：Temizkan, Orcun; Kumar, Ram L.; Park, SungJune; Subramaniam, Chandrasekar

  摘要：Software vulnerabilities have become a serious concern because unpatched software runs the risk of being exploited by hackers. There is a need for software vendors to make software patches available in a timely manner for vulnerabilities in their products. We develop a survival analysis model of software vendors' patch release behavior and test it using a data set compiled from the National Vulnerability Database, United States Computer Emergency Readiness Team, and vendor Web sites. This mode...
• Understanding Contingencies Associated with the Early Adoption of Customer-Facing Web Portals AI翻译

  摘要：Web-based portals extend many convenient and collaborative capabilities to consumers and are being adopted by small firms with ever greater frequency, especially in the context of health care. The early adoption of patient portals by ambulatory-care clinics (outpatient health providers) presents a unique opportunity to more fully understand the characteristics of supply-side adopters in a context where firms (ambulatory-care clinics) are extending digital services to consumers (patients). Usin...
• Attracted to or Locked In? Predicting Continuance Intention in Social Virtual World Services AI翻译

  摘要：Internet-based social virtual world (SVW) services have aroused extensive interest among academicians and practitioners. The success of SVW services depends heavily on customers' continuance usage, a topic not yet adequately investigated in information systems research. It is unclear to what extent, and how, the existing theories can be extended to explain the continuance usage of such services. In consideration of the distinctive features of these services, this study adapts the dedication-co...
• Supporting Agile Organizations with a Decision Guidance Query Language AI翻译

  摘要：Decision optimization is widely used in many decision guidance and support systems (DGSS) to support business decisions such as procurement, scheduling, and planning. In spite of rapid changes in users' requirements, the implementation of DGSS is typically rigid, expensive, and not easily extensible, which is in stark contrast to the agile implementation of management information systems (MIS) based on the database management systems (DBMS) and SQL technologies. This paper focuses on the Decis...
• Information Security Outsourcing with System Interdependency and Mandatory Security Requirement AI翻译

  摘要：The rapid growth of computer networks has led to a proliferation of information security standards. To meet these security standards, some organizations outsource security protection to a managed security service provider (MSSP). However, this may give rise to system interdependency risks. This paper analyzes how such system interdependency risks interact with a mandatory security requirement to affect the equilibrium behaviors of an MSSP and its clients. We show that a mandatory security requ...
• Contract Performance in Offshore Systems Development: Role of Control Mechanisms AI翻译
  作者：Srivastava, Shirish C.; Teo, Thompson S. H.

  摘要：Although control theory has often been invoked to explain the coordination between client and vendor for information systems development (ISD), insights into its moderating effects for explicating ISD contract performance, especially in the offshore context, is rather limited. Such insights would en able better understanding of variables that have complementary or substitutive effects on performance. Further, the control literature talks about different control modes (e.g., formal and informal...
