Distributed Development And Product Line Decisions, Ram Bala, V. Krishnan, Wenge Zhu Dec 2012

Distributed Development And Product Line Decisions, Ram Bala, V. Krishnan, Wenge Zhu

Information Systems and Analytics

Distributed product development is becoming increasingly prevalent in a number of industries. We study how the global distribution of product development impacts the profit-maximizing product line that a firm offers. Specifically, we formulate a model to understand the linkage between cost arbitrage as a driver of distributed development and consequent market implications such as customer perceived quality loss to remotely developed products. Analysis of the model reveals that a firm should expand the product line for a development-intensive good only at intermediate values of cost advantage and quality loss. We modify the base model to include development capacity constraints as …

Creating A Repository For The Design And Delivery Of Web Services, John D. Delano, Atish P. Sinha, Hemant Jain Dec 2012

Creating A Repository For The Design And Delivery Of Web Services, John D. Delano, Atish P. Sinha, Hemant Jain

Business Administration Faculty Publications

Existing web service repositories are not well suited to handle the multi-layered representation of web services, nor are they able to support multiple development methodologies. We describe the design and development of a repository called Web Service Crawler that supports both a traditional development methodology for the initial design of services, and an agile approach for the design of composite applications. Web Service Crawler is developed based on a set of theory-based design characteristics, and includes novel facets to represent multi-layered web services, such as workflow, composition, and layer. The positive evaluation results indicate that Web Service Crawler can be …

The Role Of Confirmation In Is Continuance Theory: A Comprehensive Meta-Analysis, John Laugesen Dec 2012

The Role Of Confirmation In Is Continuance Theory: A Comprehensive Meta-Analysis, John Laugesen

Publications and Scholarship

This paper provides a meta-analysis of Information Systems Continuance (ISC) theory, specifically focusing on the relationships that Confirmation has with Satisfaction, Perceived Usefulness and Continuance Intention. A comprehensive literature review for the years 2001 to 2012 revealed 75 ISC studies from 72 papers. The results of this meta-analysis indicate the robustness of ISC theory and model, with large effect sizes for the three key relationships. Moderator analyses indicate larger effect sizes for nonconvenience samples (versus convenience samples) and educational/eLearning Information Systems and personal Information Systems (versus corporate Information Systems). Implications of the results are discussed, along with implications for researchers …

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns Dec 2012

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns

MIS/OM/DS Faculty Publications

We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on IT professionals‟ job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior, in general, and for IT professionals, in particular. From a universalistic perspective, HRM practices individually and in combination exhibit independently additive effects on job search behavior. Our study contrasts this perspective with configurational theory, hypothesizing that proposed idealtype configurations of HRM practices have synergistic effects on job search behavior. We contribute to the IT and broader HRM literature by theoretically explicating and …

Perception Of African Youth On Personal Computer Utilization: The Case Of Ethiopia And Rwanda, S. Negash Nov 2012

Perception Of African Youth On Personal Computer Utilization: The Case Of Ethiopia And Rwanda, S. Negash

Faculty and Research Publications

The tendency to pursue innovativeness and adopt new technologies has been found more likely with younger individuals and a strong relationship between attitude and personal computer (PC) utilization has been found. However, research in these areas is mainly focused on high-income countries. Do these findings hold for low-income countries? What are the perceptions of African youth on the factors that impact PC use? There is a dearth of micro-level studies that promote understanding about the behavior of individuals in low-income countries. This study looked at demographic data including age, gender, grade level, region, and prior experience among 228 youth from …

Equilibrium Financing In A Distribution Channel With Capital Constraint, Bing Jing, Xiangfeng Chen, Gangshu (George) Cai Nov 2012

Equilibrium Financing In A Distribution Channel With Capital Constraint, Bing Jing, Xiangfeng Chen, Gangshu (George) Cai

Information Systems and Analytics

There exist capital constraints in many distribution channels. We examine a channel consisting of one manufacturer and one retailer, where the retailer is capital constrained. The retailer may fund its business by borrowing credit either from a competitive bank market or from the manufacturer, provided the latter is willing to lend. When only one credit type (either bank or trade credit) is viable, we show that trade credit financing generally charges a higher wholesale price and thus becomes less attractive than bank credit financing for the retailer. When both bank and trade credits are viable, the unique equilibrium is trade …

Principles For Conducting Critical Realist Case Study Research In Information Systems, Donald E. Wynn, Clay K. Williams Sep 2012

Principles For Conducting Critical Realist Case Study Research In Information Systems, Donald E. Wynn, Clay K. Williams

MIS/OM/DS Faculty Publications

Critical realism is emerging as a viable philosophical paradigm for conducting social science research, and has been proposed as an alternative to the more prevalent paradigms of positivism and interpretivism. Few papers, however, have offered clear guidance for applying this philosophy to actual research methodologies. Under critical realism, a causal explanation for a given phenomenon is inferred by explicitly identifying the means by which structural entities and contextual conditions interact to generate a given set of events. Consistent with this view of causality, we propose a set of methodological principles for conducting and evaluating critical realism-based explanatory case study research …

A Computational Analysis Of Bundle Trading Markets Design For Distributed Resource Allocation, Zhiling Guo, Gary J. Koehler, Andrew B. Whinston Sep 2012

A Computational Analysis Of Bundle Trading Markets Design For Distributed Resource Allocation, Zhiling Guo, Gary J. Koehler, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

Online auction markets play increasingly important roles for resource allocations in distributed systems. This paper builds upon a market-based framework presented by Guo et al. (Guo, Z., G. J. Koehler, A. B. Whinston. 2007. A market-based optimization algorithm for distributed systems. Management Sci. 53(8) 1345–1458), where a distributed system optimization problem is solved by self-interested agents iteratively trading bundled resources in a double auction market run by a dealer. We extend this approach to a dynamic, asynchronous Internet market environment and investigate how various market design factors including dealer inventory policies, market communication patterns, and agent learning strategies affect the …

From Clickstreams To Searchstreams: Search Network Graph Evidence From A B2b E-Market, Mei Lin, M. F. Lin, Robert J. Kauffman Aug 2012

From Clickstreams To Searchstreams: Search Network Graph Evidence From A B2b E-Market, Mei Lin, M. F. Lin, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

Consumers in e-commerce acquire information through search engines, yet to date there has been little empirical study on how users interact with the results produced by search engines. This is analogous to, but different from, the ever-expanding research on clickstreams, where users interact with static web pages. We propose a new network approach to analyzing search engine server log data. We call this searchstream data. We create graph representations based on the web pages that users traverse as they explore the search results that their use of search engines generates. We then analyze the graph-level properties of these search network …

Meaningful Use And Meaningful Curricula: A Survey Of Health Informatics Programs In The U.S., Kai Koong, Madison Ngafeeson, Lai Lui Aug 2012

Meaningful Use And Meaningful Curricula: A Survey Of Health Informatics Programs In The U.S., Kai Koong, Madison Ngafeeson, Lai Lui

Journal Articles

The introduction of the US government’s Meaningful Use criteria carries with it many implications including the training curriculum of healthcare personnel. This study examines 108 health informatics degree programmes across the USA. First, the courses offered are identified and classified into generic classes. Next, these generic groupings are mapped to two important frameworks: the Learning to Manage Health Information (LMHI) academic framework; and the Meaningful Use criteria policy framework. Results suggest that while current curricula seemed acceptable in addressing Meaningful Use Stage 1 objective, there was insufficient evidence that these curricula could support Meaningful Use Stage 2 and …

Hedonic Valuation Of Online Game Participation, Robert J. Kauffman, Kwansoo Kim, Byungjoon Yoo Aug 2012

Hedonic Valuation Of Online Game Participation, Robert J. Kauffman, Kwansoo Kim, Byungjoon Yoo

Research Collection School Of Computing and Information Systems

We use hedonic valuation to establish a basis for valuing the time a user participates in an online gaming community. We distinguish between utilitarian and hedonic value. Our application involves elements of both utilitarian and hedonic value, however, the latter is much more important. We use an extensive data set involving a massive multi-player online role-playing game (MMORPG) from Korea. We specify and test econometric models that reflect the appropriate empirical structure for the setting, based on information about the players and the activities they engage in. The results permit us to estimate the hedonic value in monetary terms for …

Valuation Of Benchmark Provisions On It Services Contracts, Robert J. Kauffman, Ryan Sougstad Aug 2012

Valuation Of Benchmark Provisions On It Services Contracts, Robert J. Kauffman, Ryan Sougstad

Research Collection School Of Computing and Information Systems

Information technology (IT) services are often subject to downward price pressures due to improvements in technology and business processes in a competitive market. When clients enter into IT services contracts, they are faced with the future risk that their services will be overpriced relative to the broader IT services market. To mitigate this risk, clients often add benchmark provisions, whereby a neutral third party assesses the prevailing market price for services. It will support fair price adjustments if the market prices are lower than the current prices. We model the decision to benchmark in order to provide managerial information on …

An Integrated Vendor-Buyer Cooperative Inventory Model For Items With Imperfect Quality And Shortage Backordering, Jia-Tzer Hsu, Lie-Fern Hsu Jul 2012

An Integrated Vendor-Buyer Cooperative Inventory Model For Items With Imperfect Quality And Shortage Backordering, Jia-Tzer Hsu, Lie-Fern Hsu

Publications and Research

We develop a model to determine an integrated vendor-buyer inventory policy for items with imperfect quality and planned back orders. The production process is imperfect and produces a certain number of defective items with a known probability density function. The vendor delivers the items to the buyer in small lots of equally sized shipments. Upon receipt of the items, the buyer will conduct a 100% inspection. Since each lot contains a variable number of defective items, shortages may occur at the buyer. We assume that shortages are permitted and are completely back ordered. The objective is to minimize the total …

The Role Of Interactivity In Interent Business On Customer Experiential Values And Behavioral Intentions, So Ra Park Jul 2012

The Role Of Interactivity In Interent Business On Customer Experiential Values And Behavioral Intentions, So Ra Park

College of Business: Dissertations, Theses, and Student Research

Customers’ experiential value is based on holistic experience customers would have when they interact with a product/service. Experiential value is defined as “relativistic preference characterizing a subject’s experience with some object” (Holbrook, 1994). Internet is characterized for interactivity and it should have a role in customers’ experiential value. Therefore, this research investigates the role of interactivity (e-store interaction, C2C interaction, and content interaction) and web store utility on intrinsic and extrinsic customer experiential value. The final dependent variable is behavioral intentions. To test the research model, a survey was designed to capture online consumers’ perception of interactivity within e-stores, experiential …

An Economic Analysis Of The Online Counterfeit Market And The Impact Of Anti-Counterfeit Technology, Xiong Zhang, Zhiling Guo, Wei Thoo Yue Jul 2012

An Economic Analysis Of The Online Counterfeit Market And The Impact Of Anti-Counterfeit Technology, Xiong Zhang, Zhiling Guo, Wei Thoo Yue

Research Collection School Of Computing and Information Systems

Counterfeiting causes hundreds of billions dollars of losses around the world every year. Due to the growing prominence of online commerce, the seriousness of the situation could soon become much worse. Hence, reaching a clear understanding of the fundamental economic incentives behind this practice is of vital importance. In this paper, we investigate a problem within which a firm selling a counterfeit product engages in price competition with a firm that sells an authentic product to a population of heterogeneous consumers. An online intermediary acts as the facilitator of both firms’ transactions and may consequently be liable for any counterfeit …

Vertical Differentiation And A Comparison Of Online Advertising Models, Mei Lin, Xuqing Ke, Andrew B. Whinston Jun 2012

Vertical Differentiation And A Comparison Of Online Advertising Models, Mei Lin, Xuqing Ke, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

Designing business models that take into consideration the role of advertising support is critical to the success of online services. In this paper, we address the challenges of these business model strategies and compare different ad revenue models. We use game theory to model vertical differentiation in both monopoly and duopoly settings, in which online service providers may offer an ad-free service, an ad-supported service, or a combination of these services. Offering both ad-free and ad-supported services is the optimal strategy for a monopolist because ad revenues compensate for the cannibalistic effect of vertical differentiation. In a duopoly equilibrium, exactly …

Pricing Online Subscription Services Under Competition, Ram Bala May 2012

Pricing Online Subscription Services Under Competition, Ram Bala

Information Systems and Analytics

In recent times, rapid advances in the field of information technology have enabled firms selling information products (for example, in the form of a CD) to provide subscription services using remote servers. Making the product versus service decision involves a trade-off. Online subscription offerings are perceived to be of lower quality because of data security and network reliability issues but can reduce or even eliminate the credible commitment (of prices) problem typically faced by firms selling durable products. We model an infinite horizon game between two symmetric firms that choose the design architecture, that is, product or service (and consequent …

Critical Success Factors Of Location-Based Services, Natalie Jun Pei Chin May 2012

Critical Success Factors Of Location-Based Services, Natalie Jun Pei Chin

College of Business: Dissertations, Theses, and Student Research

Location-based services evolved with the advancement in mobile technology and wireless technology. Researchers have studied location-based services in terms of privacy, trust, and user acceptance. Statistics suggest the percentage of location-based services users is still relatively low. Therefore, the main objective of this study was to gain a comprehensive and holistic understanding of the critical success factors of location-based services. The electronic brainstorming approach was used to gather the opinions of an expert group of practitioners, researchers, and users on the critical success factors of location-based services. Through grouping similar factors together based on past literature, 15 categories of critical …

Crisis Response Information Networks, Shan L. Pan, Gary Pan, Dorothy E. Leidner Apr 2012

Crisis Response Information Networks, Shan L. Pan, Gary Pan, Dorothy E. Leidner

Research Collection School Of Accountancy

In the past two decades, organizational scholars have focused significant attention on how organizations manage crises. While most of these studies concentrate on crisis prevention, there is a growing emphasis on crisis response. Because information that is critical to crisis response may become outdated as crisis conditions change, crisis response research recognizes that the management of information flows and networks is critical to crisis response. Yet despite its importance, little is known about the various types of crisis information networks and the role of IT in enabling these information networks. Employing concepts from information flow and social network theories, this …

Sentiment Analysis: A Study On Product Features, Yanyan Meng Apr 2012

Sentiment Analysis: A Study On Product Features, Yanyan Meng

College of Business: Dissertations, Theses, and Student Research

Sentiment analysis is a technique to classify people’s opinions in product reviews, blogs or social networks. It has different usages and has received much attention from researchers and practitioners lately. In this study, we are interested in product feature based sentiment analysis. In other words, we are more interested in identifying the opinion polarities (positive, neutral or negative) expressed on product features than in identifying the opinion polarities of reviews or sentences. This is termed as the product feature based sentiment analysis. Several studies have applied unsupervised learning to calculate sentiment scores of product features. Although many studies used supervised …

Does Complexity Deter Customer-Focus?, Sendil K. Ethiraj, Narayanasamy Ramasubbu, M. S. Krishnan Feb 2012

Does Complexity Deter Customer-Focus?, Sendil K. Ethiraj, Narayanasamy Ramasubbu, M. S. Krishnan

Research Collection School Of Computing and Information Systems

Economic models suggest that firms use a simple cost-benefit calculation to evaluate customer requests for new product features, but an extensive organizational literature shows the decision to implement innovation is more nuanced. We address this theoretical tension by studying how firms respond to customer requests for incremental product innovations, and how these responses change when the requested innovation is complex. Using large sample empirical analyses combined with detailed qualitative data drawn from interviews, we find considerable variance in the relationship between customer demands, complexity, and investments in incremental innovations. The qualitative study revealed the importance of organization structures, competitive pressures, …
