The ubiquity, universality, uniqueness and unison of u-commerce will provide two principal benefits for individual users and businesses: increased convenience as well as more personalized and customized services. However, u-commerce will also bring emerging issues such as a greater degree of privacy concerns th...

Purpose – This paper aims to investigate processes of how RFID-enabled systems affect consumers' trust and acceptance of u-commerce, emphasizing a feedback loop where consumers' post-transaction trust affects their initial trust. Design/methodology/approach – A simulation model using system dynamics (SD) is developed to show the importance of trust issues involving RFID technology, decomposing complex processes of trust building in u-commerce into a set of feedback loops with a causal-loop diagr...

Many classification tasks can be viewed as ordinal. Use of numeric information usually provides possibilities for more powerful analysis than ordinal data. On the other hand, ordinal data allows more powerful analysis if compared to nominal data. It is therefore important not to overlook knowledge about ordinal dependencies in data sets used in data mining. This paper investigates data mining support available from ordinal data. The effect of cons...

The growing interest in e-government raises the question of stages in e-government development. A few stage models for e-government have been proposed. Without a common e-government stage model, different research in e-government may be based on different stage models. This presents a difficulty in comparing and understanding different research results. In this research, we synthesize the existing e-government stage models so that there is a common frame of reference...

Technical communicators can and should play an important role in the development of information systems to improve the usability of the systems. Besides writing user guides and training material, technical communicators can engage in four other tasks to add value to information systems development: acting as user advocate, writing online help, writing system and error messages, and providing advice on interface design. We assert that technical communicators’ involveme...

There are two main approaches to improving the effectiveness of database interfaces.

co-authored with Chan, H., Wei, K.

With the proliferation of end-user computing and empowerment of end users in the organizations, the user-database interface is increasingly being recognized as an important research area. A user-database interface consists of two key components: the data model and the query language. Database management system designers can manipulate these two components to produce an effective database interface to maximize user task performance. However, in order to do th...

This paper describes an experiment designed to investigate the use of structural constraints and surface semantics by modeling experts. The experimental results indicated that when interpreting information models, modeling experts focused almost entirely on the structural constraints, and ignored the surface semantics, even in situations where the structural constraints were in contradiction to the real world situation. These biases exhibited by model...

In spite of many theoretical models, the role of exogenous factors in accepting object-oriented technology has not been satisfactorily demonstrated. By comparing two competing models, our study examined the role and location of exogenous variables in explaining user acceptance of object-oriented technology. Based on the results, we developed a new model that combined the key ideas of both TAM and TPB and showed that both models are necessary in understanding the unique role of each exogenous va...

Previous research suggests that computer security countermeasures are effective in preventing computer abuse in organizations. However, the computer abuse problem still persists despite such measures. This study examines the sociological perspective of Internet abuse that explains a causal link between abusive behavior and an actor's psychological state, drawn on theory of pluralistic ignorance (TPI). Pluralistic ignorance is a form of erroneous social interference that is both an immediate caus...

The signal flow graph (SFG) is a way of expressing linear algebraic equations. Thus, SFG has been effectively applied to solve sparse linear systems. In this paper the authors apply SFG to solve the goal programming problem. The SFG approach to goal programming has many promising advantages-ease of manipulating sparse matrices, conceptually simple ways to explain sensitivity analysis, and the graphical illustration of the solution process.

Unified Modeling Language (UML) is the standard visual modeling language for Object Oriented (OO) systems development, but it has been criticized for its complexity, inconsistent semantics, and ambiguous constructs. A set of complexity indices for UML and the nine diagramming techniques in UML was compiled recently. The complexity analysis is formulated based on the number of constructs, associations, roles, and so forth, in a modeling method. We argue that this set of metrics provides an indic...

Ubiquitous commerce or u-commerce is the combination of traditional e-commerce and wireless, television, voice and silent commerce. U-commerce implies ubiquity, universality, uniqueness and unison. It is not a replacement for other types of commerce, but an extension of them. While bringing many benefits, there are challenges and impediments to overcome. Research is needed to assess the value of u-commerce and to address its related issues and challenges. Questions...

Much of the previous literature on ubiquitous computing (UbiComp) has been limited to case studies, reporting innovative practices of specific technologies (e.g., RFID) and social issues. There is a general paucity of research on strategic application of UbiComp, especially to small businesses. To address this issue, this study provides a broad overview of the current practices of UbiComp in leading countries and presents possible future directions. Then, the effects of UbiComp on small business...
