Globally, almost every nation is facing some form of water crisis (World Commission on Water 2000). In Australia, the sport and recreation industry is one of the highest consumers of water. Other high water consuming industries (such as agriculture and farming) have been forced to adhere to strict managerial and governance reform due to the water crisis, yet in the sport and recreation industry, such changes are yet to be implemented and fully realised across the sector.

This research examines the impacts of drought and sustainable water management for sport and recreation. Specifically, it provides a case study of sport and recreation provision in a municipality that has already undergone considerable reform due to long-term drought. Sport and recreation use water for purposes such as irrigation of playing fields/pitches, filling swimming pools, stadium amenities and facilities, kitchens, maintenance and cleaning, and clubhouse amenities.

For sports that are heavy users of water for the maintenance of playing fields (such as soccer, Australian Rules football, rugby league, rugby union, grass and clay tennis courts to name a few) the impacts of drought and water restrictions have been severe. Some sports have reported an increase in the risk of injury to participants because of the condition of un-watered playing fields (Sport and Recreation Victoria 2007). Others have been forced to delay or shorten their seasons (Sleeman 2007), or worse still, cancel training and organised competition completely (Connolly and Bell 2007). While the impact of water restrictions has been profound on most sports, there are some sports that are not heavy water users and the impact of drought and water restrictions has been minimal. This problem creates issues and apparent inequities raising the need to further examine water consumption in sport and recreation. The potential outcome that arises is that the future of those sports that cannot conduct their competitions may be disadvantaged, while other sports that do not have such problems may be able to flourish.

Water, and those who control the supply of it, then defines which sports are able to flourish and sustain sport development pathways, compared to those whose survival may be in jeopardy. This research explores the stakeholder management and governance issues that have resulted for sport and recreation in the City of Greater Geelong (CoGG) located in Victoria, Australia--a region in long-term water crisis. The supply of sport and recreation facilities in the CoGG (like most municipalities in Australia) is largely the responsibility of the municipal council. The corporation responsible for the supply of water to the municipality is Barwon Water.

Although other sport and recreation facilities exist in the CoGG, the municipal council of CoGG owns and maintains over 120 sporting ovals (including the stadium used by its professional Australian Football League (AFL) team, the Cats), six swimming pools, and three golf courses. The CoGG host their professional AFL team, a range of local, national and international sport events, and provide a wide range of sport and recreation facilities for the community residents.

Eight interviews were conducted in total. Interviews were conducted with representatives from CoGG municipal council (who are responsible for the delivery of sport and recreation services and facilities in Geelong), and representatives from Barwon Water (who are responsible for the ongoing provision and maintenance of sport and recreation services and facilities) through the provision of water. Results show that the ten highest users of water in the municipality are sport and recreation facilitieswhich between them use almost one-third of the city's total water consumption (City of Greater Geelong 2006).

The municipal council is under considerable pressure to find ways to continue to provide sport and recreation opportunities for community members, as well as professional athletes and teams who use these facilities despite water restrictions. After all, these facilities provide benefit to spectators and participants, as well as businesses that rely on visitors to Geelong for sport and recreation events.

Due to such pressures, from 2007, the CoGG and Barwon Water agreed to provide the sport and recreation sector with water allocations rather than to be denied of all water under the water restriction regimes in place in the municipality. During 2007 summer sport season, this allowed the CoGG to keep 16 of its 120 sporting ovals open for participation through allocating all available water to these fields in order to keep them safe and playable. However, CoGG and Barwon Water were required to devise a rating scale to determine which sports (and sport facilities) were to share the allocated water, and which were not. These decisions also had knock on effects through sports. In order to ensure the safety of the playing surfaces, the CoGG and Barwon Water also restricted use of fields to competition only, therefore sport participants were forced to train on local beaches and other parkland areas-transferring issues of safety and public liability to other locations and facilities in the community. Further, it was reported that scheduling of competition seasons and individual matches; as well as the allocation of "home ground" gate receipts and concessions profits were required to be governed by the CoGG and Barwon Water as the competing sports were unable to agree. Perhaps more importantly, the rating scale developed for water allocation also resulted in some sports being rated as ineligible for water and as a result were unable to stage their entire competitions.

Clearly, the water allocation rating scale, and approach taken in this municipality to the continued delivery of sport and recreation has provided a workable solution. However, this study also signals that new stakeholders have entered the arena for the governance of sport. Governance structures in sport and recreation are being impacted as a result of the water crisis.

Those making decisions about which sport and recreation activities and/or facilities will be assisted with water resources are being made by local councils and water corporations. Sport managers are being required to understand existing areas of knowledge (such as turf management) in different ways, to gain knowledge in new areas (such as sustainable water management), and to lobby new stakeholder groups (such as water corporations) in order to secure their futures. The continued existence of some sports is no longer in the hands of governing bodies, but in the hands of local councils, and water corporations.

Clearly, any of the solutions implemented as discussed above, require multiple stakeholders to interact, and to reach agreement in order to assist in sustainable management of water in sport and recreation. In this sense, the management of water in sport (and all other industries) is more than a rational decision about policy, legislation, restrictions and resource allocations. It is a social and political process requiring scholarly attention for practical solutions.

One objective of government is to provide services at least cost whilst maintaining or improving service quality. While this may be an important objective, questions are being asked whether services can be provided more efficiently and effectively by the private rather than by the government sector. The shift of service provision from the public to the private sector is known as outsourcing or contracting out. The objective in this study is to critically examine whether the contracting out of services by local government to the private sector is an efficient management practice.

The contracting out of Parks and Grounds Maintenance services for the City of Kingston in the State of Victoria, Australia, is used as an exploratory case study to identify the variables associated with management decision-making in the contracting out process. Factors relevant to the contracting out decision such as the criteria used in selecting a contractor; the evaluation of a contractor’s performance; and any subsequent changes to management practice relating to the contracting out of the services are identified and discussed.

Political forces were found to be an important consideration in the initial contracting out decision, and the selection of a contractor was influenced by the potential to avoid costs. It was also found that under-bidding and associated cost /profit constraints lead to contractors engaging in non-sustainable environmental practices which resulted in the degradation of the local government’s Parks and Gardens assets. A sustainable asset management philosophy as opposed to an avoidable costs approach now underpins the contracting out process to ensure the preservation of such assets. Further, administrative processes have been revised to make tender specifications more prescriptive, critical components of services have been brought back in-house, and management practices have been amended so that a greater degree of control is exercised over contractors’ activities.

Strengthening links between school and community is critical for improving people's participation in environmental issues. However, Mexican education programmes are generally unrelated to rural students' life experience and are planned without considering either teachers' or students' opinions. This article describes the participatory construction of a preparatory school environmental education (EE) programme in Ixtlan de Juarez, a Mexican indigenous community internationally recognised for sustainable forest management. The qualitative research methods used are based on the action research methodology. Results from interviews conducted with the preparatory school's headmaster, the coordinator, and nine teachers provided the needed documentation of the school site for contextualising learning activities. Feedback during focus groups with six students, three teachers, five local communal authorities, and two researchers highlighted that all participants perceived the need for creating an educational programme focused on local forest management. The contents and activities of the programme were designed by the focus group's participants. The programme has been continuously taught by teachers and forest workers since 2005 and was officially integrated with the preparatory school science curriculum in 2006. This participative educational experience has thus transformed the mandatory school curriculum in Ixtlan.

While Australian firms have generally recognised the value of continuous improvement (CI) in improving performance, many have yet to develop systems to ensure that the efforts of the CI program are focussed on issues of strategic importance to the company. In fact, as recognised in operations management generally, CI activities can have a significant impact on the development of strategy as well as its implementation. The research reported here uses a CI mapping methodology to chart the relationship between CI and strategy in small- to medium-sized manufacturers. Analysis of the link between the firms’ strategies and CI programs indicates that most firms involved in the study made little attempt to link the two and some appear to be unaware of any need to do so. However, such findings seem to be dependent on company size, the maturity of the CI program and the competitive position of the firm. The paper also includes an examination of the role of operations and shopfloor CI in company strategy, particularly as related to SMEs.

Purpose – The purpose of this paper is to examine the monetary policy transmission mechanism for the Fiji Islands using a structural vector autoregressive (SVAR) model for the period 1975 to 2005.

Design/methodology/approach – The SVAR model investigates how a monetary policy shock – defined as a temporary and exogenous rise in the short-term interest rate – affects real and nominal macro variables; namely real output, prices, exchange rates, and money supply.

Findings –
The results suggest that a monetary policy shock statistically significantly reduces output initially, but then output is able to recover to its pre-shock level. A monetary policy shock generates inflationary pressure, leads to an appreciation of the Fijian currency and reduces the demand for money. The paper also analysed the impact of a nominal effective exchange rate (NEER) shock (an appreciation) on real output and found that it leads to a statistically significant negative effect on real output.

Practical implications –
The findings of this study should be of direct relevance to the research and policy work undertaken at the Reserve Bank of Fiji.

Originality/value – For a small economy, such as Fiji, where monetary policy is key to sustainable macroeconomic management, this is the first paper that undertakes a dynamic analysis of monetary policy transmission. The paper uses time series data over three decades and builds a structural VAR model, rooted in theory. This paper will be of direct relevance to the Reserve Bank of Fiji. The approach and model proposed will also be useful for applied monetary policy researchers in other developing countries where inflation rate targeting is a key element of the monetary policy setting.

Rangelands are considered critical ecosystems in the Nepal Himalayas and provide multiple ecosystem services that support local livelihoods. However, these rangelands are under threat from various anthropogenic stresses. This study analyzes an example of conflict over the use of rangeland, involving two villages in the Mustang district of Nepal. This prolonged conflict over the use of rangeland rests on how use rights are defined by the parties, that is, whether they are based on traditional use or property ownership. Traditionally, such conflicts in remote areas were managed under the Mukhiya (village chief) system, but this became dysfunctional after the political change of 1990. The continuing conflict suggests that excessive demand for limited rangelands motivates local villagers to gain absolute control of the resources. In such contexts, external support should focus on enhancing the management and production of forage resources locally, which requires the establishment of local common property institutions to facilitate sustainable rangeland management.

Cloud-based service computing has started to change the way how research in science, in particular biology, medicine, and engineering, is being carried out. Researchers in the area of mammalian genomics have taken advantage of cloud computing technology to cost-effectively process large amounts of data and speed up discovery. Mammalian genomics is limited by the cost and complexity of analysis, which require large amounts of computational resources to analyse huge amount of data and biology specialists to interpret results. On the other hand the application of this technology requires computing knowledge, in particular programming and operations management skills to develop high performance computing (HPC) applications and deploy them on HPC clouds. We carried out a survey of cloud-based service computing solutions, as the most recent and promising instantiations of distributed computing systems, in the context their use in research of mammalian genomic analysis. We describe our most recent research and development effort which focuses on building Software as a Service (SaaS) clouds to simplify the use of HPC clouds for carrying out mammalian genomic analysis.

Membrane bioreactor (MBR) technology has been used widely for various industrial wastewater treatments due to its distinct advantages over conventional bioreactors. Treatment of textile wastewater using MBR has been investigated as a simple, reliable and cost-effective process with a significant removal of contaminants. However, a major drawback in the operation of MBR is membrane fouling, which leads to the decline in permeate flux and therefore requires membrane cleaning. This eventually decreases the lifespan of the membrane. In this paper, the application of aerobic and anaerobic MBR for textile wastewater treatment as well as fouling and control of fouling in MBR processes have been reviewed. It has been found that long sludge retention time increases the degradation of pollutants by allowing slow growing microorganisms to establish but also contributes to membrane fouling. Further research aspects of MBR for textile wastewater treatment are also considered for sustainable operations of the process.

Quality testing by suppliers has significant ramifications for downstream supply chain participants and retail consumers. This article focuses on such implications accounting for the fact that suppliers often enjoy discretion in quality testing and reporting. Under a discretionary testing and reporting environment, we show that a supplier can improve the market's perception of product quality by engaging in self-imposed production cuts. Production cuts dampen supplier incentives to engage in excessive quality testing, putting the supplier and the market on a more equal information footing. This reduces the market's need to skeptically discount product quality to protect itself. The improved market perception, then, reduces quality testing demand, introducing cost savings. The result that costly production cuts can improve quality perceptions indicates that the groundwork for influencing market perceptions may have to be laid upfront, even prior to acquiring private information, providing a contrast to routine signaling models.

Sustainable development is a growing area of interest in organisations. Particularly those that have large energy demands for processing, use dwindling raw materials or produce a great deal of waste through production. Knowing those processes that can contribute to making an organisation more sustainable provides a great advantage both in terms of project implementation success and in measurable Triple Bottom Line returns.

In previous research we identified that many of the Information Technology processes used to assist organisations in developing sustainable practices were more clearly suited as Knowledge Management processes (Van Der Meer and Sinnappan, 2008), however less empirical study has been done to categorise them meaningfully.

In this study we have taken these Knowledge Management processes and categorised them according to the sustainable development practice where we identify they can be of service based on Waage et al (2003). Through this we are hoping to develop a framework for organisations to determine what Knowledge Management processes are needed to achieve the particular sustainable development. We may also be able to judge what steps an organisation needs to take to develop further sustainable practices in other areas.

Development of a framework for knowledge management tools in sustainable development would assist industries in determining the best processes for these sustainable projects. This framework also contributes to the body of knowledge on sustainable development and Information Technology.

Objective: To evaluate the Arthritis Self-Management Course (ASMC) when applied in a nationwide context.

Methods: Four hundred fifty-two people who participated in the ASMC across Australian states took part in a longitudinal followup study. ASMC is a 6 week, 2 h group educational program designed to assist people with chronic illness to better manage their condition. Measures of program effectiveness included health status and service utilization. Data were collected on 3 occasions: before intervention (baseline) and 6 months and 2 years after the program.

Results: Several indicators of health status showed improvement at 6 months following the ASMC. These included reduction in pain (4%; p < 0.001), fatigue (3%; p < 0.01), and health distress (12%; p < 0.001) as well as increase in self-efficacy (6%; p < 0.001). Increased self-efficacy was a significant predictor of positive change in health status. Health-related behaviors such as aerobic exercise also increased, with the proportion of people who did little or no exercise decreasing by up to 8%. These changes were sustained at 2 years. There was an increase in use of analgesics at 6 months and an increase in use of nonsteroidal antiinflammatory drugs at 2 years. No changes in healthcare utilization (physician visits, allied health visits, and hospitalizations) were observed.

Conclusion: The ASMC is a widely applied program in which participants benefit through a reduction in pain, fatigue, and health distress. Although the absolute changes in health status are small, the low cost and wide application of the intervention suggests the program may have a substantial public health effect.
