- Description: In this paper global optimisation-based techniques are studied in order to increase the accuracy of medical diagnosis and prognosis with FNA image data from the Wisconsin Diagnostic and Prognostic Breast Cancer databases. First we discuss the problem of determining the most informative features for the classification of cancerous cases in the databases under consideration. Then we apply a technique based on convex and global optimisation to breast cancer diagnosis. It allows the classification of benign cases and malignant ones and the subsequent diagnosis of patients with very high accuracy. The third application of this technique is a method that calculates centres of clusters to predict when breast cancer is likely to recur in patients for which cancer has been removed. The technique achieves higher accuracy with these databases than reported elsewhere in the literature.

- Description: In difficult times business operators are looking for clever and affordable ways to grow their enterprises. This paper seeks to make a contribution to a better understanding of proactive environmental and innovation strategies for SMEs and the interaction between demand and supply towards sustainable and innovative business practices. The paper discusses the combined outcomes of the exit survey of a greening small business 2008 pilot program and the entry survey for the 2009 online training and networking version of the program, which fuses environmental, business and ICT- enabled skilling to enhance both SME entrepreneurship and innovation. The study suggests that SME business sustainability cannot be reduced to an oversimplified business case and that pro-environmental strategy adoption and behaviour, and particularly behavioural change, is highly complex. The outcomes of this research are expected to contribute to good practice in environmental and innovation skilling for SMEs, especially skilling that differentiates between supply and demand side skilling and brings together the two sides in a proactive resource acquisition, knowledge transfer and networking environment.

- Description: In economically challenging times business operators are looking for clever and affordable ways to grow their enterprises. This paper discusses the role of women entrepreneurs’ in proactively greening their small business. The paper highlights the combined outcomes of the exit survey of a greening small business 2008 pilot program and the entry survey for the 2009 online version of the training and networking program, which fuses environmental, business and ICT-enabled skilling to enhance both SME entrepreneurship and innovation. The study suggests that while reported environmental attitudes between male and female entrepreneurs do not differ significantly, women’s motivations differ from male entrepreneurs in terms of greening their business; and women are more proactive in pursuing green networking opportunities, where they can interact with like-minded businesses, access more clients, source alternative resources and expand their green business networks.

- Description: High levels of student engagement have been linked with better student learning outcomes, such as the quality of their output. With marketing students accounting for a high percentage of business school undergraduates, it is important that the level of engagement is determined and drivers of engagement identified. Marketing has traditionally been delivered in a teachercentric model, as opposed to a student-centric model which better encourages independent learning. Important aspects of the latter model are interactivity, active and collaborative learning, and enriching educational experiences. The author conducted focus groups with business students, and preliminary findings reveal that the instructor’s approach and the nature of the assignments do affect student engagement. A preliminary model of student engagement is proposed which will be tested in the quantitative research phase.

- Description: Objectives: This study aims to support the training of Traditional Chinese Medicine practitioners by embedding an expert diagnostic model for arthritis into an Intelligent Interactive Learning Environment (IILE). Background: The increasing prevalence of Traditional Chinese Medicine (TCM) outside China is characterised by the emergence of university level practitioner training and stringent regulatory requirements. TCM differential diagnosis is a difficult task that was traditionally taught by exposure to large numbers of patients in a master-apprentice context. In university degree programs, students and novice diagnosticians cannot have the exposure to cases possible in the traditional context. An online system that engages students in the interactive construction of a virtual case and provides immediate feedback on the appropriateness of student actions and the accuracy of diagnostic conclusions can enhance student learning. The system, an Intelligent Interactive Learning Environment (IILE) is based on an approach that has been shown to improve learning outcomes in intensive care nurse training. Methods: An expert model of diagnostic reasoning elicited from TCM expert practitioners lies at the core of the IILE. The knowledge acquisition is performed using an argumentation tree representation that has been shown to be effective in structuring complex knowledge and facilitating engineer - expert interactions. Problems associated with keeping knowledge bases up to date are mitigated with the use of a knowledge model known as ripple down rules permits dynamic updating of knowledge so that knowledge bases evolve over time. A simple narrative model builds up the virtual case study as user interaction proceeds. Results and discussion: This article reports preliminary results in the study that includes an overview of TCM differential diagnosis, the argument tree, the ripple down rule representation and the narrative based IILE. Segments of the knowledge model based solely on TCM literature are illustrated.

- Description: The attraction sector’s ability to enhance service quality is fundamentally important to its future sustainability. Attempts to enhance performance within the sector have suffered from the lack of a standard instrument for measuring service quality perceptions. This study sought to address this issue by piloting an instrument designed to measure visitor levels of perceived service quality. The instrument was piloted on 133 visitors to four purpose built attractions in Victoria, Australia. Analysis of the data resulted in a purified 17-item instrument, called ATTRACTQUAL and proposed that two dimensions, interactions and outcomes, underlie attraction visitors’ perceptions of service quality.

- Description: Current approaches for the design of Online Dispute Resolution (ODR) systems involve the replication of Alternative Dispute Resolution practices such as mediation and negotiation. Though such systems have been found to be popular, there are concerns that these systems fail to take into account judicial practices. In this paper a system that supports disputants' decisions making when engaged in an online dispute is advanced. The system, Re-Consider, is an Australia Family Law ODR system, that is based on judicial reasoning modelled with Bayesian belief networks and provides disputants with decision support in the dispute. It is believed that this approach provides disputants with an online resolution process that will help them to reach outcomes that take judicial practices into account and presents a step toward more deliberative form of online dispute resolution.

- Description: Web services are playing a pivotal role in e-business, service intelligence, service science and information systems. This article will examine how the main players make decisions for activities in web service lifecycle (WSLC) and propose a holistic model for decision making in web services. More specifically, this article first examines main players in web services. It also reviews the existing web service lifecycles and proposes a demand-driven web service lifecycle for web service requesters. It will then examine six driving factors for web services, look at their interrelationships and propose a holistic model for decision making in web services, C6, which consists of six Cs: communication, competition, coordination, collaboration, cooperation and control, taking into account the main players in web services and web service lifecycle (WSLC). The proposed approach will facilitate research and development of web services, e-services, service intelligence, service science and service computing.

- Description: Being a victim of identity theft can be a devastating and life-changing event. Once the victim discovers the misuse they need to begin the process of recovery. For the "lucky" victims this may take only a couple of phone calls and a small amount of time; however, some victims may experience difficulties for many year. In order to recover, victims of crime require support and assistance; however, within Australia this support is sadly lacking. In order to identify the issues currently faced by victims of identity theft as they work through the recovery process, a Grounded Theory methodology was identified as most appropriate. This paper provides a brief overview of the history of the research project; a brief introduction of grounded theory with a focus on preconceived ideas and their implications; and a description of the research project currently being undertaken. A discussion of some issues experienced when using grounded theory within an IT department with very little experience of qualitative research will be provided, along with some preliminary results.
