Reputation Stretching In Online Auctions, Jianqing Chen, Mei Lin, Andrew B. Whinston
Reputation Stretching In Online Auctions, Jianqing Chen, Mei Lin, Andrew B. Whinston
Research Collection School Of Computing and Information Systems
Reputation systems are ubiquitously employed in the online marketplaces to provide information on users’ abilities and trustworthiness. We focus particularly on the problem of reputation stretching, the extension of an established reputation into a new market. By examining various factors—market size, the expected performance in the expanding market, and the risk of performance in the expanding market—we characterize conditions that affect bidder’s stretching decision in the expanding market. Moreover, we analyze both the short-term and the long-term expanding cases, and obtain contrasting results in the two settings.
Escalation And De-Escalation Of Commitment To Information Systems Projects: Insights From An Approach-Avoidance Process Model, Gary Pan, Shan Ling Pan
Escalation And De-Escalation Of Commitment To Information Systems Projects: Insights From An Approach-Avoidance Process Model, Gary Pan, Shan Ling Pan
Research Collection School Of Accountancy
We view escalation and de-escalation of commitment as processes involving recurring instances of approach-avoidance conflict. This paper outlines an approach-avoidance process model for describing and analyzing escalation and de-escalation of commitment in information systems projects. In the model, the sequential mapping of project events is integrated with a model of approach-avoidance conflict that identifies periods of gradual evolution at two separate levels of social analysis (project and work) that are punctuated by sudden, revolutionary periods of rapid change. By conceiving the processes of commitment escalation and de-escalation as sequences of events involving approach-avoidance conflicts, researchers may develop a deeper understanding …
Supply Chain Information Sharing In A Macro Prediction Market, Zhiling Guo, Fang Fang, Andrew B. Whinston
Supply Chain Information Sharing In A Macro Prediction Market, Zhiling Guo, Fang Fang, Andrew B. Whinston
Research Collection School Of Computing and Information Systems
This paper aims to address supply chain partners' incentives for information sharing from an information systems design perspective. Specifically, we consider a supply chain characterized by N geographically distributed retailers who order a homogeneous product from one manufacturer. Each retailer's demand risk consists of two parts: a systematic risk part that affects all retailers and an idiosyncratic risk part that only has a local effect. We propose a macro prediction market to effectively elicit and aggregate useful information about systematic demand risk. We show that such information can be used to achieve accurate demand forecast sharing and better channel coordination …

Information Technology, Production Process Outsourcing, And Manufacturing Plant Performance, Indranil Bardhan, Jonathan W. Whitaker, Sunil Mithas
Management Faculty Publications
What is the role of information technology (IT) in enabling the outsourcing of manufacturing plant production processes? Do plant strategies influence production outsourcing? Does production process outsourcing influence plant performance? This research addresses these questions by investigating the role of IT and plant strategies as antecedents of production outsourcing, and evaluating the impact of production outsourcing and IT investments on plant cost and quality. We develop a theoretical framework for the antecedents and performance outcomes of production outsourcing at the plant level. We validate this theoretical framework using cross-sectional survey data from U.S. manufacturing plants. Our analysis suggests that plants …

Tacit Knowledge, Nonaka And Takeuchi Seci Model And Informal Knowledge Processes, Siu Loon Hoe
Research Collection School Of Computing and Information Systems
The organizational behavior and knowledge management literature has devoted a lot attention on how structural knowledge processes enhance learning. There has been little emphasis on the informal knowledge processes and the construct remains undefined. The purpose of this paper is to highlight the importance of informal knowledge processes, propose a definition for these processes and link them to the socialization and internalization processes suggested by Nonaka and Takeuchi in the SECI model. The paper offers a fresh perspective on how informal knowledge processes in organizations help to enhance the organization’s learning capability. It will enable scholars and managers to have …

Information Systems and Operations Management: Faculty Publications & Other Works
Every fall, thousands of high school swimming coaches across the country begin the arduous process of preparing their athletes for competition. With a grueling practice schedule and a dedicated group of athletes, a coach can hone the squad into a cohesive unit, poised for any competition. However, oftentimes all preparation is in vain, as coaches assign swimmers to events with a lineup that is far from optimal. This paper provides a model that may help a high school (or other level) swim team coach make these assignments. Following state and national guidelines for swim meets, we describe a binary integer …

Improving Disaster Response Efforts With Decision Support Systems, Steven M. Thompson, Nezih Altay, Walter G. Green Iii, Joanne Lapetina
Management Faculty Publications
As evidenced by Hurricane Katrina in August, 2005, disaster response efforts are hindered by a lack of coordination, poor information flows, and the inability of disaster response managers to validate and process relevant information and make decisions in a timely fashion. A number of factors contribute to current lackluster response efforts. Some are inherent to the complex, rapidly changing decision-making environments that characterize most disaster response settings. Others reflect systematic flaws in how decisions are made within the organizational hierarchies of the many agencies involved in a disaster response. Slow, ineffective strategies for gathering, processing, and analyzing data can also …

Technology Adoption In Supply Chain Management: A Meta-Analysis Of Empirical Findings, George Mangalaraj, Anand Jeyaraj, Edmund Prater
ISSCM Faculty Publications
Electronic linkages between organizations are an important aspect of modern day supply chains. Organizations implement disparate information / communication systems to integrate their suppliers and customers in a supply chain. Though the underlying technologies and protocols of such information systems may differ, they do possess a common characteristic: they all span boundaries of the supply chain partners. Collectively labeling such systems as supply chain management information systems (SCM-IS), we examine a variety of information systems that support the activities in a supply chain. Specifically, we examine two distinct phenomena related to these information systems: the intention to adopt SCM-IS and …
Missing In Action: The Information System Artifact In Information Systems Adoption And Use, Anand Jeyaraj, Kevin P. Duffy
Missing In Action: The Information System Artifact In Information Systems Adoption And Use, Anand Jeyaraj, Kevin P. Duffy
ISSCM Faculty Publications
Despite considerable research on information systems adoption and use by individuals, little is known about how the information system (IS) artifact itself affects adoption and use. Prior research has generally treated the IS artifact as a “blackbox” such that it remained peripheral to the central questions asked regarding adoption and use. This paper presents a feature-centric “IS artifact rating” scheme and shows one way in which to unravel the blackbox of the IS artifact and examine its effect on adoption and use. Implications for research and practice are also presented.

An Agent-Based Model Of Trade With Distance-Based Transaction Cost, Kumar Venkat, Wayne W. Wakeland
Systems Science Faculty Publications and Presentations
This paper describes an application of agent-based modeling to investigate the effect of a distance-based transaction cost on trade. Long-distance trade is rapidly increasing, but may ultimately be constrained by our ability to move material goods between sellers and buyers. Unlike information exchange, trade in material goods is dependent on the price of oil and vulnerable to future scarcities of oil. In addition, there are growing concerns about greenhouse gas emissions from long-distance transportation. Our purpose in this study is to take the first step in understanding the impact of a distance constraint on free global trade using a simple …

Dynamic Generation Of A Table Of Contents With Consumer-Friendly Labels, Trudi Miller '08, Gondy Leroy, Elizabeth Wood
CGU Faculty Publications and Research
Consumers increasingly look to the Internet for health information, but available resources are too difficult for the majority to understand. Interactive tables of contents (TOC) can help consumers access health information by providing an easy to understand structure. Using natural language processing and the Unified Medical Language System (UMLS), we have automatically generated TOCs for consumer health information. The TOC are categorized according to consumer-friendly labels for the UMLS semantic types and semantic groups. Categorizing phrases by semantic types is significantly more correct and relevant. Greater correctness and relevance was achieved with documents that are difficult to read than with …

Millions of people search online for medical text, but these texts are often too complicated to understand. Readability evaluations are mostly based on surface metrics such as character or words counts and sentence syntax, but content is ignored. We compared four types of documents, easy and difficult WebMD documents, patient blogs, and patient educational material, for surface and content-based metrics. The documents differed significantly in reading grade levels and vocabulary used. WebMD pages with high readability also used terminology that was more consumer-friendly. Moreover, difficult documents are harder to understand due to their grammar and word choice and because they …
