Trustworthiness In Mhealth Information Services: An Assessment Of A Hierarchical Model With Mediating And Moderating Effects Using Partial Least Squares (Pls), Shahriar Akter, John D'Ambra, Pradeep Ray
Faculty of Commerce - Papers (Archive)
The aim of this research is to advance both the theoretical conceptualization and the empirical validation of trustworthiness in mHealth (mobile health) information services research. Conceptually, it extends this line of research by reframing trustworthiness as a hierarchical, reflective construct, incorporating ability, benevolence, integrity, and predictability. Empirically, it confirms that partial least squares path modeling can be used to estimate the parameters of a hierarchical, reflective model with moderating and mediating effects in a nomological network. The model shows that trustworthiness is a second-order, reflective construct that has a significant direct and indirect impact on continuance intentions in the context …

The relationship between satisfaction and loyalty has been well explored in services marketing or customer relationship management. In this study, the authors studied the relationship of 7 types of service variables under “amusement” factor. Amusement is one of the three factors extracted from 21 mobile information services. Among many different frameworks of satisfaction-loyalty, we used the framework of “past use behavior” on “satisfaction”, and then of “satisfaction” on “continued use intention” (or loyalty), resulting in a strong support of the existing model with positive significant influence on the both paths. Further, our research reveals that, on the both paths, there …

Disruptions In Information Flow: A Revenue Costing Supply Chain Dilemma, Albert Munoz, Michael D. Clements
Faculty of Commerce - Papers (Archive)
The integration of supply chains as a mechanism for value creation is largely dependent on continuous flowof real time accurate information from the customer back upstream to the manufacturer. This ideal is oftenunachievable when disruptions in the flow of information and materials are known to regularly occur in somemanufacturing supply chains. This paper focuses on quantifying the potential lost sales revenue attributed toinformation and material delays in a supply chain using discrete event simulation of the Beer Distribution Game.Results indicate a direct relationship between lost sales revenue and delay times. When exposed to severallevels of delay such disruptions will cause …

Systems Dynamics Modelling Of Human And Information Aspects Of Network-Centric Configurations, Helen M. Hasan
Systems Dynamics Modelling Of Human And Information Aspects Of Network-Centric Configurations, Helen M. Hasan
Faculty of Commerce - Papers (Archive)
This paper is based on the definition of a network-centric structure as one which enables members of an organisation to create and leverage information to increase competitive advantage through the joint efforts of creative individuals and independent teams. While the technical components of this environment are enabling, the organisational and behavioural components generate value as traditionally competitive workers strive to cooperate in self-directed, distributed teams. Many organisations are now complex hybrids of hierarchical and network-centric configurations and there is a need to increase our understanding of their human and informational aspects. Due to its suitability for managing complexity without reducing …

Towards Executive Information Systems Adoptions By Knowledge Workers: An Extension Of The Technology Acceptance Model To Account For Social-Cultural Factors, Emmanuel Ikart
Faculty of Commerce - Papers (Archive)
In recent years a number of organisations have implemented executive information systems (EIS) in order to improve the performance gains on their executives’ job. Although the use of EIS is important to executives, majority of executives are unwilling to use EIS because of their design failures. By using social factors, habits and facilitation conditions variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM) to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on the research in progress in Australia on the adoption and usage of EIS by …

In today’s hypercompetitive business environments hardly anyone questions the important role that information technology plays. The conventional wisdom is that IT is necessary for business survival and that careful deployment and management of IT resources and capabilities leads to enhance value for the business (Ying and Ram, 2004). Despite this recognition of information technology as a key enabler of organisational strategy (Preston and Karahanna, 2004), and despite recent investment in IT in Nigerian economy (Ajayi, 2003) an increasing number of organisations in this economy have found themselves unable to apply IT effectively (Modum, 1983). For corporate IT to be meaningful …

Knowledge Management In Information Technology Help Desk: Past, Present And Future, Kar Yin Leung, Sim K. Lau
Faculty of Commerce - Papers (Archive)
Information technology has changed the way organizations function. This resulted in the reliance of help desks to deal with information technology related areas such as hardware, software, and telecommunication. Besides, the adoption of business process reengineering and downsizing have led to the shrinkage of the size of help desk. The shorter information technology product life cycle has worsened the situation by increasing the already sizeable help desk’s user base. Consequently, the help desk has to cover more information technology products and resolute more technical enquiries with less staff. Thus, the outcome is clear that users have to wait comparably longer …

Information Technology (IT) has converted a majority of organizational activities to automatic and electronicbased. This conversion greatly increases Help Desk (HD)'s coverage on IT related areas. Alternatively, the adoption of business process reengineering and downsizing has led to the shrinkage of the size of HD. This not only leads to the loss of priceless knowledge, but also coerces HD to provide more service with less staff - the outcome is clear that users have to wait comparably longer before HD staff is available. This paper describes how generic Knowledge Management process can be customized to improve support process in HD.

This paper represents an overview of a field trial for a patient data management system used in ambulatory care. Its purpose is to give an outline of the issues that allow technological enablement of electronic patient data management in the delivery of home-based medical care. While the replacement of more traditional paper-based patient data management using PDAs as a collection platform are technically straightforward, the organizational realignment of an electronic document management system require careful study and deployment in order to maximize success. We outline the methodological considerations for document management diffusion within this e- Health setting and describe the …
Online Information Values For Recreational Travellers: A Review Of Online Sources In Decision Making For An Unfamiliar Long Haul Destination, Robert Grant
Faculty of Commerce - Papers (Archive)
Acquisition or purchase of travel arrangements involves an exchange of information which is theoretically suited for transfer from offline to online interaction. The ability to digitise material and ease access through searchability based on metatags (Reedy and Schullo, 2004, p 276) make the internet a potentially ideal medium for information gathering and exchange. This paper reviews the value of information sources for consumer decision making for a high involvement experience product with multiple and variable components and points to further research which help our understanding of the value of electronic networks.
Source Of Value Online For Recreational Travellers: Customer Information Needs In The Buying Process And Internet Capability, Robert Grant
Source Of Value Online For Recreational Travellers: Customer Information Needs In The Buying Process And Internet Capability, Robert Grant
Faculty of Commerce - Papers (Archive)
The information needs of buyers of high involvement recreational travel products are potentially a source of customer value in their decision making process. The internet's ability to provide large amounts of information in real time with high levels of customer convenience are compounded by the ability to deliver information from multiple sources. In theory then, the internet seems able to largely replace the value delivered by retail travel intermediaries in the physical world. This critical review suggests however that the physical world intermediaries and online information sources are more likely to be complementary rather than competitive resources for shoppers for …
Analysis Of Information Cost Incurred In Foreign Exchange Risk Management By Smes, Shyam S. Bhati
Analysis Of Information Cost Incurred In Foreign Exchange Risk Management By Smes, Shyam S. Bhati
Faculty of Commerce - Papers (Archive)
In this study, the theory of Information Cost developed by Casson (1995) is used to explain the various intormatlOn cost associated with foreign exchange risk management by SMEs. From the application of Casson's theory, 1t 1S concluded that the SMEs incur maximum cost in collecting, communicating and synthesising information while managing foreign exchange risk. Also, the SMEs do not seem to have the potential to reduce these information costs because of ,their limited bargaining capacity in relation to service provIders. As such, SMEs would fit the description of "optimal" organisation as defined by Casson (1995) due to the trade-offmade by …

A Metaphorical Study Of Information Seeking Using Q Methodology, Joseph A. Meloche, Kate Crawford
Faculty of Commerce - Papers (Archive)
This brief paper examines a metaphorical perspective for information science. Metaphorical understanding, like learning itself, is a fundamental component in the movement from the known to the unknown. Adopting this perspective has the potential to inform and further advance the study of characteristics ofinformation and.how it relates to emerging knowledge. This will be demonstrated by an examination ofthe metaphors used by theorists to describe how users approach information.
