The Effects of Website Information Utility on the Outcomes of User-Website Interactions

Joe Hasley, IS doctoral student

Abstract:
This study investigates the relationships between website information content utility and various outcomes of user interactions with e-tail websites. Although previous research has consistently identified high quality information content as a critical factor of successful e-commerce websites, those studies have not reported how to identify the specific information cues that comprise high-utility information content. In this study, we demonstrate how a new instrument, the Website Information Content Survey, can be used to accurately and reliably assess website information content. We also demonstrate how the MaxDiff statistical method can be used to assess website information content utility. Finally, to investigate the relationships between website information content utility and various outcomes of user-website interactions (perceived information quality, perceived design quality, engagement, trust, and risk), a 4x2 full-factorial experiment was performed

Dynamic Interaction: A Measurement Development and Empirical Evaluation of Knowledge Based Systems and Web 2.0 Decision Support Mashups

Brandon Beemer, IS doctoral student

Abstract
The research presented in this dissertation focuses on the organizational and consumer need for knowledge based support in unstructured domains, by developing a measurement scale for dynamic interaction. Addressing this need is approached and evaluated from two different perspectives. The first approach is the development of Knowledge Based Systems (KBS) designed to operate in unstructured domains. By meshing the system attributes of KBS and Decision Support Systems (DSS), researchers and developers have begun designing KBS for unstructured domains that tract with the user's iterative decision process and allow the user to evaluate alternative solutions. The second approach to providing knowledge support in unstructured domains is through knowledge synthesization. The latest trend in Web 2.0 research focuses on mashup applications that are designed to synthesize knowledge by semantically connecting disjointed information and knowledge sources (Blake and Nowlan, 2008).

  • The focus of this dissertation is on developing and empirically evaluating a new IS construct that can be used by researchers to quantify dynamic interaction. Dynamic interaction is empirically evaluated in two IS domains: KBS and eCommerce mashups. The nomological net of dynamic interaction is initially quantified in the KBS domain, and then is expanded from evaluating this new construct in the mashup domain.
  • This dissertation consists of two parts and four chapters. The first part is titled 'Knowledge Based System's Support of Unstructured Domains Through Dynamic Interaction' and has two chapters that cover KBS designed for unstructured domains by including dynamic interaction. The 1st chapter is titled 'Knowledge Based Systems to Support Unstructured Decisions: A Literature Review' and provides a literature review of recent KBS, of which are designed for unstructured domains and include an iterative user interface. The 2nd chapter is titled 'Dynamic Interaction in Knowledge Based Systems: An Exploratory Investigation and Empirical Evaluation'. This study empirically investigates the KBS discussed in the previous chapter, which are designed for unstructured domains and include dynamic interaction.
  • The second part of the dissertation is titled 'Decision Support Mashups ' Knowledge Synthesization Through Dynamic Interaction' and is composed of two chapters that discuss knowledge synthesization in unstructured domains through dynamic interaction in mashups. The 3rd chapter is titled 'Mashups: A Literature Review and Classification Framework'. It presents a mashup literature review, a mashup classification framework, and provides a literary foundation for the final chapter of the dissertation. The final and 4th chapter is titled 'Decision Support Mashups in Unstructured Domains: An Empirical Evaluation of Dynamic Interaction' and performs an empirical evaluation of dynamic interaction in decision support mashups.

Knowledge Based Support for Unstructured Domains

Brandon Beemer, IS doctoral student

Abstract:
The research presented and proposed in this dissertation proposal addresses the organizational need for knowledge based support in unstructured domains. Addressing this need is approached and evaluated from two different perspectives. The first approach is the development of Knowledge Based Systems (KBS) designed to operate in unstructured domains. By meshing the system attributes of KBS and Decision Support Systems (DSS), researchers and developers have begun designing KBS for unstructured domains that tract with the user’s iterative decision process and allow the user to evaluate alternative solutions. The second approach to providing knowledge support in unstructured domains is through knowledge synthesization. The latest trend in Web 2.0 research focuses on mashup applications that are designed to synthesize knowledge by semantically connecting disjointed information and knowledge sources (Blake and Nowlan, 2008).

The focus of the proposed dissertation is on knowledge based support in unstructured domains. It will consist of two parts and four chapters. The first part covers KBS designed for unstructured domains. The first chapter (published in the "Handbook on Decision Support Systems") provides a literature review of recent KBS, of which are designed for unstructured domains and include an iterative user interface. The second chapter (accepted for publication at "Decision Support Systems") empirically investigates the KBS discussed in the previous chapter, that are designed for unstructured domains.

The second part of the dissertation will be composed of two chapters that discuss knowledge synthesization in unstructured domains through web mashups. Web 2.0 Mashups: A Literature Review and Classification Framework (published in "Future Internet") presents a web mashup literature review, a mashup classification framework, and provides a foundation for the final chapter in the proposed dissertation which is not yet completed. The final chapter will perform an empirical evaluation of decision support mashups and will include calibration, trust, and decision quality as dependent variables in the research model.

Empirical Analysis of Hybrid Open Source Software Model: Determination of Efficiency and Governance

Mohamed Sidahmed
Monday July 13 at 11AM in CU299

Abstract:
Over the past decade, open source software (OSS) projects underwent significant changes and restructuring, symbolizing venture from the original approach of producing open source code by volunteer contributors. The latest trend, which is fueled by commercial organizations, systems integrators, and IT vendors’ interest in OSS, involves the joint collaboration between open and proprietary concerns.

This study investigates the implications of a collaborative hybrid OSS development model from the perspective of the OSS project. By extending transaction cost economics and interorganizational cooperation frameworks to the OSS domain, the research investigates factors affecting network governance structure of this hybrid alliance. Theory predicts that efficient forms of collaborative transaction leads to perceived satisfaction with an alliance.

The study examines factors that contribute to satisfactory institutional governance and underlying principles that influence OSS projects to engage in hybrid relationships with commercial partners. Moreover, the research identifies the necessary dimensions of interorganizational cooperation and safeguards, which minimize project’s vulnerability to detrimental behavior by commercial partners.

Data was collected across OSS projects to analyze the impact of commercial partners’ involvement on project efficiency and governance. Results demonstrate that OSS projects seek to establish arrangements that give rise to atypical structure for efficient management of the development process. Results reveal that the formation of institutional establishment based on streamlined information flow, flexible non-formal relationship, collective collaboration responsibility, and moderation of influence effect give rise to a favorable form for governing transactions.

The study also found that trust and branding play significant roles in reinforcing a thriving governance structure. Findings support the notion that hybrid projects achieve gains in product distinctiveness, yet collaboration is fragile to commercial parties’ behavior of seeking self-interest. The emerging structure yields a perceived meritorious outcome for the OSS project; strongly suggesting that transaction cost efficiencies are realized.

Practical implications for the study include identifying significant factors that contribute to OSS project efficiency and optimal governance, in addition to, establishing brand identity as a mutual benefit that binds the alliance. Hybrid OSS project success is largely dependent upon how well these factors are managed.

The research fills a gap in empirical analysis of both OSS hybrid development model and OSS business model research.

The Effect of Technology Features and Complexity on Technology Acceptance and IT Training in the Internal Audit Profession

Hyo-Jeong Kim
Wednesday, May 6, 2009

Abstract:
Although various information technologies have been studied with the Technology Acceptance Model (TAM) and training research, the study of specific technology features and complexity for professional groups employing information technologies such as internal auditors (IA) has been limited. To address this gap, I extend TAM and IT training research with technology features and complexity among IA professionals and test the model using a sample of internal auditors provided by the Institute of Internal Auditors (IIA). Two independent studies were conducted to examine the effect of technology features and complexity on technology acceptance and training.

The first study tests system usage, perceived usefulness, and perceived ease of use with technology features and technology complexity. More basic features such as database queries, ratio analysis, and audit sampling were more accepted by internal auditors while more advanced features such as digital analysis, regression/ANOVA, and classification are less accepted by internal auditors. As technology complexity increases, perceived ease of use decreased so that system usage decreased. Based on path analysis using TAM variables, the results indicated that path magnitudes were significantly changed by features and technology complexity. Perceived usefulness had more influence on feature acceptance when basic features were used, and perceived ease of use had more impact on feature acceptance when advanced features were used.

The second study tests the effect of advanced feature training on technology acceptance, computer self-efficacy, and performance at both feature and software level. I expect that the advanced feature training increases technology acceptance and computer self-efficacy of advanced feature and audit software, and increases the performance of audit tasks. I also expect that feature acceptance is positively associated with software acceptance and feature self-efficacy is positively associated with software self-efficacy. Advanced feature training is expected to have more influence on perceived ease of use than perceived usefulness.

Analysis of Factors Influencing Adoption and Usage of Knowledge Management Systems and Investigation of Wiki Technology as an Innovative Alternative to Traditional Systems

Andrea Hester
Wednesday April 8, 1:30PM, CU299

Abstract:
Knowledge management strives for effective capture and application of organizational knowledge, a valuable resource imperative in sustaining an organization. In an effort to better achieve knowledge management initiatives, factors underlying increased adoption and usage of the various technologies implemented as knowledge management systems are of considerable interest. Advances in technology have fostered new approaches to knowledge management in the form of web-based collaborative technologies supporting environments of social computing. Wiki technology is an emerging trend with the potential to serve as an efficient and effective knowledge management system by providing benefits of improved communication and collaboration, improved work processes, and improved knowledge sharing and reuse. Deployment of technological solutions are deemed organizational innovations giving rise to potential problems of resistance, and additional obstacles including organizational cultures lacking an environment conducive to effective knowledge creation and sharing. With Innovation Diffusion Theory as a foundation, this research examines the factors underlying adoption and usage of knowledge management systems, with further attention given to the specific case of Wiki technology. The original diffusion model is expanded to include an additional independent variable as well as a moderating variable of Personal Innovativeness in IT.

Governance of Hybrid Open Source Projects: A Transaction Cost Perspective

Mohamed Sidahmed
February 24 from 11:30AM to 1PM in CU299

Abstract:
Over the past decade open source software (OSS) governance has undergone significant changes that represent a major departure from the original reasoning of producing free open source code by volunteer contributors. The latest trend in OSS is the joint collaboration between open source projects and vendors of commercial and proprietary "closed" code. This study investigates the implications of a joint governance model from the perspective of OSS project. By extending transaction cost economics and interorganizational cooperation framework to the OSS domain, I propose to investigate the causal factors affecting network governance structure of this hybrid form of alliance. Data will be collected from open source projects to examine the impact of commercial vendors" involvement on project governance. Results will demonstrate why open source projects seek to establish arrangements that give rise to a new construct for efficient management of OSS software development. Theory predicts that satisfactory governance structure leads to more efficient form of collaborative transaction. The study also proposes to examine factors that contribute to a satisfactory institutional governance structure. The study will reveal the underlying principles that influence OSS project to engage in hybrid relationship. In addition the study identifies necessary dimensions of interorganizational cooperation that minimize the vulnerability and safeguard project from detrimental vendor involvement. The study has practical implications for open source project by examining the effect of established brand identity and identifying significant factors that impact "outsourcing" decision. Namely, departure from a pure volunteer model ("make model") to adoption of commercial and proprietary companies" joint efforts (";buy model").

Computer-Aided Multimodal Credibility Assessment

Matthew Jensen, Post Doctoral Researcher, University of Arizona
Thursday, February 7, 12:00PM - 1:30PM, CU299

Abstract:
Reliable credibility assessment is very difficult for humans to perform, yet it is a critical task for many organizations and businesses. This presentation will share methods of automated, unobtrusive credibility assessment of face-to-face interactions through analysis of linguistic, vocalic, and kinesic behavior. The findings of experiments designed to validate these methods will be presented. The presentation will also share the results of an experiment which examined the performance of novice users of a prototype system in a credibility assessment task. Findings regarding the system’s effects on the decision maker, decision making processes, and judgment outcomes will be presented.

Assessing Virtual and Hybrid Communities of Practice at a Large Multi-State Healthcare Provider

Richard Mann, CSIS Doctoral Student, Business School, University of Colorado Denver
Thursday, March 20, 12:00PM - 1:30PM, CU299

Abstract:
This talk describes an effort to evaluate efficacy of Communities of Practice (CoP) for knowledge sharing at a very large geographically disparate healthcare provider, specifically with respect to job role. A web-based survey instrument was used to poll the beliefs of healthcare workers participating in one or more of 50 CoPs sponsored by Catholic Health Initiatives (CHI) to determine utilization and perceived benefits. The survey incorporated 25 Likert scale questions to evaluate attitudes towards and utilization of as well of perceived benefits of CoPs. Each participant was also asked several demographic questions, and two open ended questions. Open ended questions are analyzed using a word count analysis. Managers were additionally asked 4 Likert scale questions and 2 open ended questions to assess their involvement and perceived benefits. The findings suggest that job role affects community members’ perceptions of the benefit and impact of communities of practice as well as their participation in such communities. Although CHI appears to be utilizing most factors affecting CoP functionality, it must account for variances in job role to increase perceived benefits from knowledge transfer within CoPs. Specifically, managerial support for time (to use the CoP) and technical training should be provided as well as developing more hybrid style communities for roles that utilize this type of interaction normally.
