Objective
This study was concerned with examining the coping and psychological adjustment of people with multiple sclerosis (MS) and determining how they were different in these dimensions from people from the general population. The role of severity and duration of illness as well as levels of social support on coping style and adjustment were also evaluated.

Method
The participants were 381 (144 men, 237 women) people with MS and 291 (101 men, 190 women) people from the general population.

Results
The results demonstrated that people with MS (particularly men) were less likely to adopt coping styles related to problem solving and seeking support and demonstrated poorer levels of adjustment on all dimensions. Adopting a wishful thinking coping style, as well as a lack of problem-focused coping or failure to seek social support, was also more likely to be associated with poorer psychological adjustment for both men and women with MS. Levels of health impairment were only minimally related to psychological adjustment, particularly for men.

Discussion
These findings highlight the importance of developing educational programs that include strategies to adopt more problem-focused coping strategies, so that people with MS can more readily adjust to their illness.

Twelve Australian and 12 Chinese heritage students from a third-year university computer ethics subject completed a Readiness for Online Learning Questionnaire; and six students from each of these two groups participated in a student-facilitated problem-solving discussion through computer-mediated communication. The questionnaire comparisons showed that the two groups of students were equally willing to self-manage their own learning, but that Australian students were significantly more comfortable with e-learning. The analysis of student postings in the CMC component showed that, collectively, Australian students posted more messages than did the Chinese students. Both groups participated equally in socialisation online; although Chinese heritage students posted a higher number of messages associated with organisational matters; and Australian students posted a larger number of message components associated with intellectual contributions to the discussion. These results are interpreted in a theoretical context and implications for practice are drawn.

This paper contends that the arts provide a foundation for the intensifying effort that leadership, creative aptitude and expertise are making to existing and emerging professions. Participation in arts-based (school and/or community) programs 'have proven to be educational, developmentally rich, and cost-effective ways to provide students the skills they need to be productive participants in today's economy' (Psilos, 2002, p. 2). In particular, this paper explores the relationship between leadership development in young people through their engagement with arts education experiences, specifically the capacity of the arts to develop the generic skills of communication, team work, problem-solving and creative interpretation-skills considered essential for productive participation in today's economy and skills that augment leadership potential.

EXDOC is an on-line export documentation system implemented by the Australian Quarantine Inspection Service [AQIS] and used currently by 90% of meat exporters. At a time when governments world-wide are increasingly committed to introducing electronic service delivery [ESD], this is a timely exemplar of innovative practice. In this paper, we consider the initial implementation of EXDOC in the meat export sector in order to identify the factors that led to the successful adoption of this system.

We consider these factors in the context of diffusion of innovation literature supplemented with Bijker’s social constructivist framework. The theoretical flexibility provided by this combination of approaches enabled us to draw out a number of implications from the data that bear on strategy formulation.

Factors found to have significant bearing on the early adoption of EXDOC included: (1) idiosyncratic factors precipitating the initial implementation (2) the constraints based on accommodating user capabilities (3) the organisational role taken by AQIS (4) diffusion as a self-reinforcing and value-adding effect.

A standard represents both a problem as a requirement of such a system and a problem solving strategy eliciting compliance to the system requirements. Over the period of shaping and stabilizing of the industry standard, AQIS was required to act as facilitator in the coordination of the actors.

The implementation of systems like EXDOC enables users to identify what they want from a system, specifying their preferences and tradeoffs. Such implementations offer opportunities for systems redesign within export business sectors with major strategic implications for the industry.

For over a decade the graphic calculator has been promoted not only as a computational tool but also as a thinking tool — for example, as an aid to enhance conceptual understanding, as a problem-solving tool and as a means of enabling students to engage in meaningful investigations. However, research studies focusing on these aspects have shown mixed results and have mostly focused on graphs and functions. This paper reports on one aspect of a case study in a year 10 mathematics classroom — the role of the graphic calculator as a thinking tool. Data from observations of nine statistics lessons and interviews with the teacher and five students are analysed from three perspectives: the teacher’s intentions with respect to the use of the graphic calculator as a tool to promote conceptual understanding as opposed to procedural competence; the opportunities afforded during the lessons for student investigation; and students’ views of how the graphic calculator enhanced conceptual understanding. The results provide insights into ways in which students perceive the graphic calculator as promoting conceptual understanding, as well as some of the difficulties encountered in practice in a classroom.

This paper outlines an introductory course in software engineering undertaken by computing students at Deakin University. The course focuses on areas of that are often not emphasized in introductory software engineering. These areas include formal problem solving, management of software development, communication, and working in groups. The approach includes the application of concepts in a collaborative group setting. Enhancements to the course have been made over a number of semesters and evidence suggests that our overall approach is working. The skills acquired by students taking this course can be applied to later courses in software engineering, particularly the capstone project course, and to professional life

Development of commercial web systems is laborious, lengthy and costly. This is partly due to the fact that the methods of their development can hardly cope with the complexity of provided services. Such services may need to be distributed and collaborative, require sophisticated software architecture, be rich in form, content and interactivity, and have a wide range of potentially casual users. While web development methodologies are slowly emerging from research methodologies, their adoption is far from wide-spread. To improve this situation, the authors propose an approach based on the observed practices of professional web developers, who openly share and reuse their web development experience, while guarding their development workproducts. To this end, we suggest to enhance web development methods, by collecting problem-solving experience of web developers, packaging it into a reusable form, and providing a navigable decision structure assisting developers in identifying proven expert solutions suitable for a given problem context.

Requirements Engineers face an emerging set of challenges, which compound the traditional Requirements Engineering (RE) challenges (stakeholder identification, domain expertise, communication, analytic skills, problem solving, ...) that have arguably still not been fully addressed. This is the challenge of RE in the world of global software development, with requirements teams working in virtual mode (possibly on different continents), with the software having to operate in multiple contexts, addressing the needs of different cultures and legal jurisdictions, and having to build sales in different marketplaces. Further the need arises to specify software that is progressively enhanced through regular releases, rather than the “green field” specification of products.

This theoretical paper introduces these challenges, and presents an initial selection of theoretical models, drawn from many and varied source disciplines, which might be employed to gain insight into various features of RE in support of global software development. To illustrate the potential relevance of this selection of models, a longitudinal case study with a recently identified software developer, to follow the specification and subsequent roll-out of a future release of a software product for sale globally, is introduced. Features of the situation faced by that organisation are highlighted, to illustrate the potential relevance of the diverse models that have been identified.

In recent years there has been considerable debate about the general decline in the number of students undertaking bachelor degrees and majors in economics. The discussion has stemmed mainly from a supply-side perspective of the economics education market. The goal of this paper is to add another dimension to the debate and report the results of a survey of employers of economics graduates. Drawing on the extensive customer services literature it is argued that a market oriented, or demand-side analysis is also an important component in redressing low student enrolments and retention. A first step in adopting a market oriented approach is to determine the skills required of the economics graduates entering the jobs market. With the support of The Economics Society of Au~tralia, twenty-nine public and private sector employers were surveyed in 2002. The aim of the survey was to establish the demand for economics graduates with bachelor and honours degrees, the skills and knowledge required of these graduates, and the performance of such graduates. The study found that economic knowledge and skill were important to employers. However, the skills rated most important by employers were the more general or 'generic' skills of clear writing, data analysis, interpersonal skills and a practical problem-solving orientation. While graduates generally performed satisfactorily in relation to the economic skills required by employers, this was not the case for generic skills. The result of the survey findings have some significant implications for the content and teaching of undergraduate economics programs. This paper outlines these implications and also discusses areas for future research It is argued that such research should aim to utilize both the demand and supplyside perspectives with the development of more precise definitions and measurement of the economic skills required by the various stakeholders in the economics education market.

Artificial neural network (NN) is an alternative way (to conventional physical or chemical based modeling technique) to solve complex ill-defined problems. Neural networks trained from historical data are able to handle nonlinear problems and to find the relationship between input data and output data when there is no obvious one between them. Neural Networks has been successfully used in control, robotic, pattern recognition, forecasting areas. This paper presents an application of neural networks in finding some key factors eg. heat loss factor in power station modeling process. In the conventional modeling of power station, these factors such as heat loss are normally determined by experience or “rule of thumb”. To get an accurate estimation of these factors special experiment needs to be carried out and is a very time consuming process. In this paper the neural networks (technique) is used to assist this difficult conventional modeling process. The historical data from a real running brown coal power station in Victoria has been used to train the neural network model and the outcomes of the trained NN model will be used to determine the factors in the conventional energy modeling of the power stations that is under the development as a part of an on-going ARC Linkage project aiming to detail modeling the internal energy flows in the power station.

This paper presents a phenomenological investigation of project managers’ experiences with the implementation of web-based employee service systems (ESS), a domain that has witnessed sharp growth in Australia in recent times. The rich, multidimensional account of project managers’ experiences with the implementation of ESS revealed the social obstacles and fragility of intraorganizational relationships that demanded a cautious and tactful approach. While arriving at such findings usually concludes the cyclical process of phenomenological study, Information Systems (IS) research usually demands some independent assessment of the empirical discovery, which led us to conducting a further study focusing on the evaluation of the collected and packaged project managers’ experience. This phenomenological evaluation is in the focus of this paper. By means of a small case study, this project engaged a number of professional teams to reflect upon the previously captured problem-solving experience and determine its applicability, usefulness and relevance in developing new web-based ESS products and services.

Despite technological advances, many postoperative patients continue to suffer unrelieved pain. The aim of this study was to identify the strategies used by postoperative patients to bring about pain management decisions. A single-group noncomparative study design was chosen using observations as the means of examining pain activities in 2 surgical units of a metropolitan teaching hospital in Melbourne, Australia. A total of 52 nurses and 312 patients participated in the study, and 316 pain activities were observed. The most common strategy used was patients acting as a passive recipient for pain relief (60%), whereas problem solving (23%) and active negotiation (17%) were less commonly used. Patients in this study were admitted for surgical treatment of a particular condition, and their subsequent pain was specifically related to this acute event. Therefore, the lack of familiarity of the situation and the severity of pain experienced may have encouraged passivity. Patients may have also felt uncertain about how to approach the pain decision, preferring to defer to nurses. Because increased pain levels can be associated with fear, patients could have been unwilling to speak with nurses to discuss their need for pain relief.

This chapter reflects upon techniques that might facilitate improved strategic decision making in a supply chain management (SCM) environment. In particular, it presents the integration of a selection of techniques adapted from an approach to systems-based problem solving that has emerged primarily in the UK over the last 20-30 years—the soft systems methodology (SSM). The results reported indicate that SSM techniques can complement existing SCM decision-making tools. In particular, this chapter outlines a framework for integrating some SSM techniques with approaches based upon the supply-chain operations reference-model (SCOR) .

Business schools are under increasing pressure to enhance the learning capability and employability of graduates. Business professional institutes and employer organizations are demanding more than the technical knowledge and skills required to perform discipline/professional specific tasks. They want graduates who can demonstrate capabilities in communication, teamwork, risk taking, decision making, problem solving, critical thinking, analytical reasoning, visioning and innovation, leadership, ethical practices, appreciation of diversity, and a commitment to social justice. Evidence in literature and reports (Karpin, 1995; Kirby, 2000; Commonwealth of Australia, 2002; Nelson, 2002) and in test data (McCowan & Richardson, 1998; Employer Survey, 1998; DETYA, 2000) shows that the employability gap7 is closed when graduates possess these generic capabilities. What is important, however, is the increasing research showing that the strategies used to develop generic capabilities lead to improved learning, both in university courses and in the workplace.

A variety of developments in nursing education in Australia including some innovative and exciting models, educational enterprises between education and industry, and evidence of developing strengths in research and professional alliances on a national level have been discussed recently. This paper presents Simulation to Practice as an example of an educational program that can maximise skill mastery for nurses in mental health fields as practised by Deakin University in Victoria, Australia. The program is multimodal and is under-pinned by a problem-solving approach and has an online presentation. The extension of nursing skills through this approach encourages nurses to take theoretical skills to practice during these scenarios which help student nurses to gain experience through simulated real life characters. These sessions, while challenging at the time, were highly valued by students and seen as a beneficial part of their learning as a beginning nurse and often instrumental in moving comprehensively trained students into mental health careers.
