Universities are increasingly turning to ‘fashionable’ education programs to attract bright, high-quality students to both under-graduate and post-graduate degree programs. Traditional offerings in technology areas, such as Information Systems and Information Technology are being augmented by newer, more marketable degrees in areas such as eCommerce/eBusiness. This paper analyses the eCommerce/eBusiness and Information Systems (IS) / Information Technology (IT) academic programs in Australian and New Zealand universities on the basis of Kotler and Fox's service offering model of educational institutions; and considers what differences exist between these two apparently similar areas of academic endeavour. Finally we look at the trends of academic program delivery in the e-age and question whether universities need to take a more consumer-product approach to the issue of attracting appropriate students.

Outsourcing of Information Technology (IT) services which are central to business strategy may be risky. Managers have made the outsourcing decision both to concentrate financially on the core competencies and to rid themselves of a troublesome and cost inefficient department. More recent research has, however, cast doubt on the promises of huge savings. In this paper, we consider the likelihood that outsourcing may lead to the loss of organisational knowledge - that organisations outsourcing their total Information Systems operations may also have lost irreplaceable tacit, cross-functional knowledge which subsisted within the minds of the professional systems analysts. The findings of our research revealed that expert systems analysts possess a unique organisational understanding and draw on this knowledge to operate efficiently in their environment. We present a model that will allow future researchers to build on our findings and examine whether outsourcing can lead to a loss of organisational memory.

Information Systems have been used for many years to analyze problems and compare options in a managed environment. The introduction of computer and information security systems into such an environment is a typical example of a situation to which an Information Systems approach can be applied. In this paper, we examine the issues peculiar to implementation of security in a healthcare environment, looking specifically at one such specially designed system, SIM-ETHICS, which takes a participational approach.

Delivered information systems are an integral part of many organisations’ information technology infrastructure. Their dynamic nature creates new challenges, not the least of which is the need to measure the quality/effectiveness of these systems. Given the size of investment in these systems, it would be invaluable for business to formulate a fresh, simple, easy to administer, multi-dimensional instrument capable of measuring the quality of delivered information systems or applications. Such an instrument would provide a practical and efficient means to pinpoint areas that key stakeholders, ranging from end-users to managers, perceive as requiring attention. In this paper, we report on the development of one such instrument. This instrument addresses key areas of performance and uses multiple statements to enhance stakeholders’ understanding of these areas.

This paper argues that the nature of IS research that deals with indigenous culture must be informed as much by context as it is by culture models, which has been the focus of such research in the past. This is considered important because it better reflects the meaning of the data collected for the researcher. To appreciate the importance of context this papers also argues that research subjects from designated individualist societies will inform the researcher in different ways from those subjects located in collectivist societies. To illustrate the practical implications of this argument the paper reports three separate case studies in IS research where the researchers reflect on the impact that a collectivist view has had on the research findings. The paper suggests that (1) similar ethnicity and appearance are significant in gaining the trust of subjects in a collectivist society; that is the researcher is part of the in-group as they belong to the same culture or ethnic group; that (2) who introduced the researcher to the subject is significant in that trust is best reflected when a member of the group/collective plays an important role in the research process itself; and that (3) an ability to (a) communicate in the natural language and (b) understand the implicit body language and (c) cultural codes is important in gaining significant and more meaningful research outcomes. This is enabled via the implicit meanings embedded in members of the collectivist society.

This paper discusses how interpersonal conflict between IS developers and clients can disrupt IS projects.  It is suggested how potential problems can be avoided by getting the 'soft' factors right which can lead to improvements in information systems development (ISD) processes.  However little is being done in most organisations to review success from this perspective.  Measurement of ISD quality tends to favour the product rather than the human drivers that influence the development of the product.  Several ideas are put forward that can be used to resolve conflict and tp better involve stakeholders in the ISD process.

Fraud is one of the besetting evils of our time. While less dramatic than crimes of violence like murder or rape, fraud can inflict significant damage at organizational or individual level.

Fraud is a concept that seems to have an obvious meaning until we try to define it. As fraud exists in many different guises, and it is necessary to carefully define what it is and to tailor policies and initiatives accordingly.

Developing a definition of fraud is an early step of a prevention program. In order to be involved in the protection function, people at all levels of an organization must be knowledgeable about fraud. In this paper, we discuss the risk of fraud from an information systems perspective, explain what fraud is and present a range of definitions of fraud and computer fraud. We argue that without clearly defining fraud, organizations will not be able to share information that has the same meaning to everyone, to agree on how to measure the problem, and to know the extent of the problem, in order to decide how much and where to deploy resources to effectively solve it.

A new unit named Information Systems in Construction was developed and taught for the first time in the School of Architecture and Building at Deakin University in Semester 1 2003 for first-year construction management students. This paper reports on key issues that arose during the unit development process and the implementation of teaching activities. Special consideration is given to the learners (first year students), the teaching environment (online teaching and learning), the unit background (information technology and information system), and the discipline (international construction). Several suggestions are outlined for improving the unit development and delivery in the next round.

The tale of research methodology in information systems is told through the fantasy of Tolkien’s Lord of the Rings. The tale is intended to be at once a piece of light hearted fun in its placement of the struggles of research methodology as an epic story but, in the tradition of the court jester, attempts to provide a new perspective on Information Systems (IS) research methodology and our struggles with positivism in particular. Our tale is one of developing a greater maturity and confidence in IS methodology and introduces postmodern methodologies to Information Systems. Our tale, our pastiche, is itself postmodern.

Systems implementation is inherently a political process. However, the majority of the literature in the area of systems implementation takes a simplistic look at factors attributed to success. These studies provide empirical evidence that “human factors” such as “top management support” contribute to a successful implementation. Rather than accept this, we challenge this view and explore two “human” issues – power and legitimacy inside systems implementation. By exploring the implementation of a learning management system at the University of New Zealand, issues such as power and legitimacy affect the way an implementation team collaborates. Systems implementation is a complex and messy process and we need to understand the implementation process, acknowledging that top management support is not always necessary to “successfully” implement a system.

The examination of a practical issue with a web site has led, in this paper, directly to the consideration of the need for, and an assessment of the impact of, an approach based on fundamental theories of ‘what is’, to examine what information systems research is and the relations of its component areas of endeavour. The paper presents an examination of the use of the philosophical field of ontologies, and specifically the use of the ontological approaches upon which to base categories of information systems research activities. This theoretical analysis is intended to be used as the basis from which to develop a methodology to undertake the development of the categorial scheme for the web site that initiated the research.

Salinisation of aquifers is an issue of great concern in the Glenelg-Hopkins region. The GlenelgHopkins region is located in south-west Victoria, south of the Great Dividing Range and covers 2.6 million hectares. The area receives an annual average rainfall of 500-910 mm and experiences a Mediterranean climate, with hot, dry summers and cold wet winters and has varied geology and soil types. Terrain characteristics, such as soil type, geology, depth-to-water table, land use and topography have been integrated into a Geographic Information System (GIS). A geostatistical approach, including the use of multiple linear regression is used to analyse the spatial variability of the relationships between aquifer salinity and terrain characteristics across the entire region. Results from this study should greatly improve knowledge of aquifer salinisation across the region. It is expected that this work will enable managers to determine the most appropriate mitigating measures for each specific area affected.

With the continually evolving social nature of information systems research there is a need to identify different “modes of analysis” (Myers, 1997) to uncover our understanding of the complex, messy and often chaotic nature of human factors. One suggested mode of analysis is that of social dramas, a tool developed in the anthropological discipline by Victor Turner. The use of social dramas also utilises the work by Goffman (1959; 1997) and enables the researcher to investigate events from the front stage, reporting obvious issues in systems implementation, and from the back stage, identifying the hidden aspects of systems implementation and the underpinning discourses. A case study exploring the social dramas involved in systems selection and implementation has been provided to support the use of this methodological tool.

Deployment of mobile technologies and applications in health care are becoming prevalent worldwide. As mobile innovation and standards in wireless continue to evolve, so does the mobile health care information systems framework. In this paper, we explore this evolving framework by synthesising current technologies, applications, issues and examining this through the actor-network theory (ANT) which seeks to understand socio-technical change by adopting a symmetric treatment of people and technologies.
