The research design for this paper is based on the critical need for greater emphasis by Australian arts organizations on relationship marketing as a means of achieving sustainability. Recent injections of government funds into the performing arts in Australia, to meet a "crisis" in financial viability and audience development, highlighted the dependence of arts organizations on government funds in building audiences. A hypothesis was developed through an analysis of the literature on relationship marketing, cultural economics and value measurement, and an analysis of the long-term outcomes of government strategies for the funding of arts marketing. The hypothesis is that while social intervention is acceptable (even desirable and necessary), and achieves the social goals of governments, market intervention reduces the benefits of relationship-building and the exchange of values between arts organizations and their audiences.

Analysis of government documents and primary research in audience development proved the hypothesis. Empirical research resulted in the development of a theory and model that describe the limits of market intervention and in the development of a definition of values in the continuum of government activity from social to market intervention. The model could be useful for governments in developing arts policy with regard to audiencebuilding. It could also be useful in demonstrating to arts managers that sustainability results not from government funding but rather from relationship-marketing strategies.

The Mount Buffalo National Park is the oldest national park in Victoria, Australia. There has been a rapid increase in the number of visitors to the park during the last decade and park management has been a concern, especially in the light of declining budgetary allocations and potential damage due to the increased visitor numbers. Policy options to increase park revenue remain unclear because of a lack of information on demand parameters and user costs. This study estimates the economic value of the park using the travel cost method (TCM) and the contingent valuation method (CVM). The TCM gives higher consumer surplus (CS) than the CVM. The CS shows that the economic value of the park is high and that there are opportunities to introduce innovative fee schemes to enhance its revenue. Present entry fee systems do not capture the economic value of the park.

In an age of globalisation, economic restructuring and rampant consumption, the "cultural industries" have come to be viewed as offering a source of social and economic salvation to declining towns, cities and regions. However, it is far from clear to what extent the arts, media and related tourism create employment, wealth, capital and community cohesion. What then is the value of the cultural industries and what concepts can be deployed to answer this question? This paper will report on one effort to devise a theoretical framework to assess the value of the cultural industries in one small Australian city. Drawing on Marxism, Pierre Boudieu and post-modem theory, it will develop a particular concept of "cultural capital" for use in quantifying and qualifying the socio-economic contribution of the cultural industries in Geelong, Victoria. It will argue that by linking Marx to Bourdieu around reformulated notions of "value" and "cultural capital", a theoretically rigorous framework can be distilled to assess and argue for the value of the arts. Such a concept has particular relevance and implications for arts managers.

I show that the principal and the agent may each prefer that the principal or the agent has imperfect information about the principal's technology in a principal-agent environment with moral hazard. Principals expend considerable resources on data cumulation and analysis. However, such investments in information acquisition are benecial only if the agent will know that the principal is not ignorant or it allows the principal to implement a dierent action. When the principal is perfectly informed about her technology, the agent prefers to be ignorant. In addition, the value of perfect information for the agency is negative if the principal would implement the same action with either possible technology. I also investigate the dierences between ex ante and ex post contracting, and the ramications of the principal being ignorant or potentially ignorant about the technology. Finally, I determine if the principal's utility varies continuously with the degree of informativeness of the agent about the principal's technology. In this vein, I determine whether the agent's uncertainty may make the principal better o if she has the less informative technology.

The use of mathematical games in primary classrooms is commonplace in Australia. This paper reports on key findings from a larger investigation exploring the impact of games on mathematical learning, student attitudes, and behaviours. 222 Grade 5 and 6 children were taught multiplication and division of decimal numbers using calculator games. This paper raises questions about the students’ attitudes towards games as a vehicle for learning mathematics. One aspect reported in this paper is an apparent difference between students’ attitudes to games usage when data were
collected quantitatively compared with qualitatively.

We analyze a principal-agent model with moral hazard in which the principal has private information about the technology. We characterize Perfect Bayesian Equilibria of the contracting game that possess the following properties: (i) a principal with a more informative technology ends up earning less profits than a principal with a less informative one does; (ii) compared to the complete information case, the actions implemented by the privately informed principal can be distorted; (iii) the agent can end up being better off when the principal has private information.

Purpose: This paper investigates the impact of the Asthma Foundation of Victoria's educational camp program on children's knowledge of asthma and its management, their feelings about asthma, and their attitudes toward physical and social activities. Parents' observations of changes in their child's behaviour and attitudes are also reported.

Design and methods: This research was descriptive and applied. It used questionnaires at four stages (directly pre- and post- camp, three-four months and ten-15 months post-camp) of an asthma education camp program to assess child asthma knowledge levels. At three months post-camp, parental observations of children's attitudes and behaviours were assessed using a questionnaire. Children's feelings toward asthma were also assessed using a questionnaire pre- and post-camp.

Results: The children surveyed displayed a better knowledge of asthma and how to manage their condition immediately after the camp. This knowledge tended to return to pre-camp levels after ten months. The children also reported less anxiety and fear about their illness, a greater sense of wellbeing, and more confidence in participating in a whole range of physical and social activities. Many parents also noted positive changes in their children in terms of activities and asthma management at three months post-camp.

Clinical implications: Although there were limitations to sustaining knowledge gained in the asthma camping program, the camping experience provided a benefit for children in terms of promoting their mental and social wellbeing. When readers consider modernising asthma education (eg shorter camps, education in everyday social settings such as schools), they need to consider retaining the key ingredients of the more traditional camping program that supports good asthma management, wellbeing and social participation.

This article develops a theoretical discussion related to the value of a phenomenological framework in contributing to contemporary nursing knowledge. Nursing is based on the understanding of patients' personal experiences and their responses to their illness. Phenomenological methodology utilizes the patient's own language to reflect meanings embedded in their health experience.

There is an increasing realisation of the importance of community or volunteer collected data for management programs that are otherwise limited by the availability of funds or resources. However, there are concerns regarding the reliability of scientific data collected by inexperienced people. We investigated the potential for community-based monitoring in Victoria’s newly established system of Marine Protected Areas. The main objectives for the study were to 1) develop a template for the scientific monitoring of marine habitats suitable for community groups, 2) assess data quality and data integrity collected by community volunteers and 3) determine a sustainable model for ongoing community participation in monitoring marine habitats. Three different habitats (subtidal, intertidal, and seagrass) were investigated and data collected by volunteers across these habitats was compared to that collected by scientists. Reliability of data collected by volunteers was dependent on habitat type and the type of measurement the volunteers were required to make. Qualitative estimates made by volunteers were highly variable across all three habitat sites, compared to quantitative data collection. Subtidal monitoring had the greatest inaccuracy for data collection, whereas intertidal reef monitoring was most reliable. Sustainability of community-based monitoring programs is dependent on adequate training for volunteers and the development of partnerships to foster greater community engagement.

Charities are becoming more businesslike in their quest to address competitive pressures and funding reductions. However, this shift may have unintended consequences. For example, the best-marketed charities are not necessarily the ones with the greatest potential for social benefit. There is currently no mechanism that attempts to evaluate the social value of charities. Borrowing from social investing and corporate social responsibility literature, the authors argue that despite the difficulties inherent in this task, there are several issues that must be considered to assess a charity's social value, and each stakeholder will consider some dimensions of social value differently. Assessing a charity's social value has several ethical and policy implications, especially given the level of governmental and foundational support for charity organizations.

Plagiarism is an interruptive act in the teaching and learning value chain. This paper analyses the impact of both plagiarism and effective assessment in the learning value chain. Effective assessment is the positive outcome. Plagiarism negates or breaks the chain. Anecdotal evidence suggests the incidences of plagiarism are increasing in faculties across the Queensland University of Technology (QUT), and where every subject/unit outline includes a statement and warning to students of the penalties of this activity, deterrence tools do not overcome the harmful impact of plagiarism on the teacher/student learning relationship. A working party established in 2000 in the Faculty of Business at QUT, examined the literature, university policies, teaching and learning practices, and examples of plagiarism and penalties in order to identify the wider learning and assessment issues surrounding plagiarism and options for action and policy. A three-semester study of acts of plagiarism and wide consultation with staff presented the working party with an opportunity to develop a set of preventative measures, and also exposed the legal, cultural and accountability issues of diverse attitudes and values.

The paper presents the findings and recommendations from the investigation, and also proposes an interpretation of marketing theory of the impact of plagiarism on the teaching and learning value chain.
