• Generating Shareable Statistical Databases for Business Value: Multiple Imputation with Multimodal Perturbation AI翻译
  作者：Melville, Nigel; McQuaid, Michael

  摘要：Business organizations are generating growing volumes of data about their employees, customers, and suppliers. Much of these data cannot be exploited for business value due to privacy and confidentiality concerns. National statistical agencies share sensitive data collected from individuals and businesses by modifying the data so individuals and firms cannot be identified but statistical utility is preserved. We build on this literature to develop a hybrid approach to data masking for business...
• Putting Money Where the Mouths Are: The Relation Between Venture Financing and Electronic Word-of-Mouth AI翻译

  摘要：External financing is critical to ventures that do not have a revenue source but need to recruit employees, develop products, pay suppliers, and market their products/services. There is an increasing belief among entrepreneurs that electronic word-of-mouth (eWOM), specifically blog coverage, can aid in achieving venture capital financing. Conflicting findings reported by past studies examining eWOM make it unclear what to make of such beliefs of entrepreneurs. Even if there were generally agre...
• Modeling Spatial and Temporal Set-Based Constraints During Conceptual Database Design AI翻译
  作者：Currim, Faiz; Ram, Sudha
  作者单位：University of Iowa; University of Arizona
  摘要：From a database perspective, business constraints provide an accurate picture of the real world being modeled and help enforce data integrity. Typically, rules are gathered during requirements analysis and embedded in code during the implementation phase. We propose that the rules be explicitly modeled during conceptual design, and develop a framework for understanding and classifying spatiotemporal set-based (cardinality) constraints and an associated syntax. The constraint semantics are form...
• Institutional Influences on Information Systems Security Innovations AI翻译

  摘要：This research investigates information security management as an administrative innovation. Although a number of institutional theories deal with information systems (IS) innovation in organizations, most of these institutional-centered frameworks overlook external economic efficiency and internal organizational capability in the presence of pressures of institutional conformity. Using Korea as the institutional setting, our research model posits that economic-based consideration will moderate...
• Generalizability of Information Systems Research Using Student Subjects-A Reflection on Our Practices and Recommendations for Future Research AI翻译
  作者：Compeau, Deborah; Marcolin, Barbara; Kelley, Helen; Higgins, Chris
  作者单位：Western University (University of Western Ontario); University of Lethbridge
  摘要：Information systems researchers, like those in many other disciplines in the social sciences, have debated the value and appropriateness of using students as research subjects. This debate appears in several articles that have been published on the subject as well as in the review process. In this latter arena, however, the debate has become increasingly like a script-the actors (authors and reviewers) simply read their parts of the script; some avoid the underlying issues whereas others curso...
• Ushering Buyers into Electronic Channels: An Empirical Analysis AI翻译
  作者：Langer, Nishtha; Forman, Chris; Kekre, Sunder; Sun, Baohong

  摘要：Despite many success stories, B2B e-commerce penetration remains low. Many firms introduce electronic channels in addition to their traditional sales channels but find that buyer usage of the e-channel over time does not keep up with initial expectations. Firms must understand the underlying factors that drive channel usage and how these factors change over time and across buyers. Using panel data pertaining to the purchase histories of 683 buyers over a 43-month period, we estimate a dynamic ...
• Effects of the Presence of Organic Listing in Search Advertising AI翻译
  作者：Xu, Lizhen; Chen, Jianqing; Whinston, Andrew
  作者单位：University System of Georgia; Georgia Institute of Technology; University of Texas System; University of Texas Dallas; University of Texas System; University of Texas Austin
  摘要：This paper analyzes how the presence of organic listing as a competing information source affects advertisers' sponsored bidding and the equilibrium outcomes in search advertising. We consider a game-theoretic model in which two firms bid for sponsored advertising slots provided by a monopolistic search engine and then compete for consumers in price in the product market. Firms are asymmetrically differentiated in market preference and are given different exposure in organic listing aligned wi...
• Managing Data Quality Risk in Accounting Information Systems AI翻译
  作者：Bai, Xue; Nunez, Manuel; Kalagnanam, Jayant R.
  作者单位：University of Connecticut; International Business Machines (IBM); IBM USA
  摘要：The quality of data contained in accounting information systems has a significant impact on both internal business decision making and external regulatory compliance. Although a considerable body of literature exists on the issue of data quality, there has been little research done at the task level of a business process to develop effective control strategies to mitigate data quality risks. In this paper, we present a methodology for managing the risks associated with the quality of data in a...
• Risk Management and Optimal Pricing in Online Storage Grids AI翻译

  摘要：Online storage service providers grant a way for companies to avoid spending resources on maintaining their own in-house storage infrastructure and thereby allowing them to focus on their core business activities. These providers, however, follow a fixed, posted pricing strategy that charges the same price in each time period and thus bear all the risk arising out of demand uncertainties faced by their client companies. We examine the effects of providing a spot market with dynamic prices and ...
• When Hackers Talk: Managing Information Security Under Variable Attack Rates and Knowledge Dissemination AI翻译
  作者：Mookerjee, Vijay; Mookerjee, Radha; Bensoussan, Alain; Yue, Wei T.
  作者单位：University of Texas System; University of Texas Dallas; City University of Hong Kong
  摘要：This paper analyzes interactions between a firm that seeks to discriminate between normal users and hackers that try to penetrate and compromise the firm's information assets. We develop an analytical model in which a variety of factors are balanced to best manage the detection component within information security management. The approach not only considers conventional factors such as detection rate and false-positive rate, but also factors associated with hacker behavior that occur in respo...
