Adopting ontology to facilitate knowledge sharing

Ontology-enabled knowledge management experiences derived from a domain ontology development project at Intel Corporation are described and assessed.

Improving the process of E-Government initiative: An in-depth case study of web-based GIS implementation

Abstract Research on E-Government has largely focused on understanding the “outcomes and outputs of the E-Government project” [Yildiz, M. (2007). E-Government research: Reviewing the literature, limitations, and ways forward. Government Information Quarterly, 24(3), 646–665.]. It is argued that the existing research on E-Government tends to oversimplify the phenomenon. To address the call, the current study focuses on the process of an E-Government initiative by loosely drawing on the ‘technology enactment framework,’ in conjunction with the ‘systems development life cycle’ approach. Using a case study orientation, this study describes in detail how a geographic information systems implementation project is conducted at a local government in the United States. Insights into E-Government initiatives are presented and discussed.

Domain-specific innovativeness and new product adoption

Domain-specific innovativeness (DSI) is redefined, tested and validated.DSI consists of product-possessing and information-possessing innovativeness.The research model was tested within the context of wearable technology.The impact of DSI on perceived attributes of wearable devices was examined.Examined the relationship between perceived attributes and purchase intention.The effects of information possessing innovativeness are highlighted. Wearable technology has recently started gaining mass market attention, but the actual adoption of the technology is not up to expectations. The current study examines the effects of consumers domain-specific innovativeness (DSI) on the adoption of wearable technology. In this study, consumer DSI is first conceptualized to have two dimensions namely, product-possessing innovativeness (PPI) and information-possessing innovativeness (IPI). The effects of PPI and IPI on perceived attributes of wearable technology (relative advantage, social image, aesthetics, and novelty) are then examined, which influence purchase intention. Exploratory and confirmatory factor analyses were conducted on a survey data from young consumers. Structural equation modeling was employed to evaluate the proposed research model. Results demonstrate that 1) the DSI construct must be examined in the two dimensions so that it can properly measure the nature and characteristics of DSI, 2) IPI plays an important role, having a positive effect on all four perceived attributes of IT innovations, 3) PPI has a positive effect on perceived social image and perceived novelty, and finally 4) all perceived attributes of IT innovations have a positive effect on consumers purchase intention of wearable devices. Implications for research and practice are discussed.

Building Enterprise Network Infrastructure for a Supermarket Store Chain

Enterprise network infrastructure has served as a vehicle on which data and information can be transferred between functional units regardless of their location. Creating the network infrastructure that enables firms and organizations to adapt to rapidly changing business needs has never been more important than now. Building the enterprise network infrastructure requires careful planning, effective design, and appropriate strategies for successful implementation. The current case study examines how a regional supermarket store chain in the retail food industry develops its enterprise network infrastructure to outperform its larger competitors. A detailed description of the evolution of the company’s enterprise network infrastructure is presented to show how the strategy of network infrastructure development has aligned with the organization’s growth strategy for the past two decades. The current case study highlights critical success factors for firms to build an effective enterprise network infrastructure that include IS planning firmly tied to critical business goals, strategic collaboration with technology vendors, and careful evaluation and selection of network services and technical details.

An Empirical Study of Standards Development for E-Businesses: A Social Network Perspective

Research on the nature of e-business standards and the organizational context in which they are developed has received little attention in the literature of IT standards and standardization. This study investigates communication patterns in online standards groups to provide insights into the nature of group dynamics among standards decision makers and its relation to the standards context. Email data is used from the ebXML standards initiative. Findings suggest that standards groups operating on the Internet appear to form a cohesive structure, despite the fact that they tend to consist of large group of participants coming from various backgrounds and industries, while their communication patterns are influenced by standards orientation. Policy implications for managers in online standards groups are presented.
