There has been an increasing focus internationally on the quality and impact of research outputs in recent years. Several countries, including the United Kingdom and New Zealand have implemented schemes to base the funding of research on research quality. The Australian government is planning to implement a Research Quality Framework (RQF) in the next few years that will impact greatly on funding of research in Australian universities. A key issue for Australian researchers is how the quality and impact of research is defined and measured in their discipline areas. Although peer review is widely used to assess the quality of research outputs, it is expensive and labour intensive. Other surrogate quality measures are often used. This paper focuses on measuring the quality of research outputs in the information systems discipline. We argue that measures such as citation indexes are inappropriate for information systems and that the publication outlet is a more suitable indicator of quality. We present a ranking list of journals for the information systems discipline, and discuss the approach we have taken in developing the list. We discuss how the ranking list may be used in defining and measuring the quality of information systems research outputs, the limitations inherent in the approach and discuss lessons we have learned in developing the list.

The professional fields of information systems and information technology are drivers and enablers of the global economy. Moreover, their theoretical scope and practices are global in focus. University graduates need to develop a range of leadership, conceptual and technical capacities to work effectively in, and contribute to, the shaping of companies, business models and systems which operate in globalised settings. This paper reports a study of the operation of industry-based learning (IBL) at three Australian universities, which employ different models and approaches, as part of a series of investigations of the needs, circumstances and perspectives of various stakeholders (program coordinator, faculty teaching staff, the students, industry mentors, and the professional body which has supported the most recent stage of this study). The focus of this paper is a discussion of salient pragmatic considerations as we attempt to conceptualise what constitutes best practice in offering industry-based learning for higher education students in the disciplines of information systems and information technology.

Teaching Information Systems (IS) to Australian tertiary students has come increasing problematic with many of them relying on a face level approach to study. This will surely affect their understanding of IS material and in turn affect their effectiveness in the workplace. This paper examines the issues behind this trend and considers Problem Based Learning (PBL) as an aid to counteract it.

This paper proposes a new model – the Information Systems Acceptance (ISA) model - to explain and predict IS acceptance. Drawing on previous literature, and the results of a series of case studies, the ISA model integrates four sets of factors influencing IS acceptance: (i) technology characteristics; (ii) management actions; (iii) service quality; and (iv) system use, user satisfaction and system outcomes. These sets of factors are drawn from well-established frameworks. Building on established theories, the model incorporates previous research, overcomes some of the limitations associated with these individual theories, and assembles IS acceptance factors into a comprehensive and useable conceptual framework.

Land-use patterns in the catchment areas of Sri Lankan reservoirs, which were quantified using Geographical Information Systems (GIS), were used to develop quantitative models for yield prediction. The validity of these models was evaluated through the application to five reservoirs that were not used in the development of the models, and by comparing with the actual fish yield data of these reservoirs collected by an independent body. The robustness of the predictive models developed was tested by principal component analysis (PCA) on limnological characteristics, land-use patterns of the catchments and fish yields. The predicted fish yields in five Sri Lankan reservoirs, using the empirical models based on the ratios of forest cover and/or shrub cover to reservoir capacity or reservoir area were in close agreement with the observed fish yields. The scores of PCA ordination of productivity-related limnological parameters and those of land-use patterns were linearly related to fish yields. The relationship between the PCA scores of limnological characteristics and land-use types had the appropriate algebraic form, which substantiates the influence of the limnological factors and land-use types on reservoir fish yields. It is suggested that the relatively high predictive power of the models developed on the basis of GIS methodologies can be used for more accurate assessment of reservoir fisheries. The study supports the importance and the need for an integrated management strategy for the whole watershed to enhance fish yields.

At last year's ACIS conference in Melbourne a panel titled 'IS: A discipline in crisis' discussed issues relating to be in disability of IS in Australia. It is not, however, just the Australian IS discipline that must deal with problems such as the need for better organisational structures and greater visibility in universities. This paper presents a comparison between the German Business Informatics discipline and the Australian Information Systems discipline. The objective is to provide another perspective on the IS discipline to raise new ideas and stimulate discussion with reference to the organisational structure of our discipline in universities.

In this paper, we consider an information system (IS) to be a set of technologies together with a set of rules about those technologies. An IS is considered to be prone to a privacy incident if it does not fully protect the private information of a user or if a dishonest user can take advantage of the privacy protection offered by the IS. This work identifies the potential privacy incidents that may occur in an IS, and proposes a framework, the MAPI Framework (Manage or Avoid Privacy Incidents), which designs IS to manage or avoid privacy incidents. The MAPI Framework can also be used for evaluating IS by identifying the missing or inappropriate technologies which may lead to privacy incidents.

While the important role of family carers has been increasingly recognized in healthcare service provision, particularly for patients with acute or chronic illnesses, the family carer's information needs have not been well understood or adequately supported by health information systems. In this study, we explore the information needs of a family carer by analyzing the extensive online diary of a Vietnamese family carer supporting his wife, who was a lung cancer patient. The study provides a deep understanding of the information needs of the family carer and suggests a four-stage information journey model including identification, searching, interpretation and information sharing, and collaboration. A number of themes emerge from the study including the key role of the carer, information filtering by the carer, information sharing and collaboration, and the influence of Vietnamese culture. The paper concludes with a discussion of the requirements for health information systems that meet the needs of family carers.

The objectives of this study were to investigate the degree to which hospital information systems are aligned with hospital strategies and how they impact on nurses. Semi-structured interviews were conducted with nine hospital staff from a range of disciplines in a large public hospital in Australia. The interviews revealed that the focus of hospital information systems on administration has meant that applications to support the patient's clinical journey have been deemed unaffordable. A consequence is that the historic use of the nurses' station as a source of verbal information about patients has continued, with negative impacts on nurses' perceived role and status, and the possible exacerbation of the clash between administrative and clinical cultures. We conclude that hospitals need clear strategies, with alignment of information systems. To do otherwise can undermine culture and morale, while disrupting workflows and patients' clinical journeys.
