A concise introduction to the key ideas and issues in the study of media economics, drawing on a broad range of case studies - from Amazon and Twitter, to Apple and Netflix - to illustrate how economic paradigms are not just theories, but provide important practical insights into how the media operates today. Understanding the economic paradigms at work in media industries and markets is vitally important for the analysis of the media system as a whole. The changing dynamics of media production, distribution and consumption are stretching the capacity of established economic paradigms. In addition to succinct accounts of neo-classical and critical political economics, the text offers fresh perspectives for understanding media drawn from two 'heterodox' approaches: institutional economics and evolutionary economics. Applying these paradigms to vital topics and case studies, Media Economics stresses the value – and limits – of contending economic approaches in understanding how the media operates today. It is essential reading for all students of Media and Communication Studies, and also those from Economics, Policy Studies, Business Studies and Marketing backgrounds who are studying the media. Table of Contents: 1. Media Economics: The Mainstream Approach 2. Critical Political Economy of the Media 3. Institutional Economics 4. Evolutionary Economics 5. Case Studies and Conclusions

Online scheduling in the Operating Theatre Department is a dynamic process that deals with both elective and emergency patients. Each business day begins with an elective schedule determined in advance based on a mastery surgery schedule. Throughout the course of the day however, disruptions to this baseline schedule occur due to variations in treatment time, emergency arrivals, equipment failure and resource unavailability. An innovative robust reactive surgery assignment model is developed for the operating theatre department. Following the completion of each surgery, the schedule is re-solved taking into account any disruptions in order to minimise cancellations of pre-planned patients and maximise throughput of emergency cases. The single theatre case is solved and future work on the computationally more complex multiple theatre case under resource constraints is discussed.

This paper describes the development of a simulation model for operating theatres. Elective patient scheduling is complicated by several factors; stochastic demand for resources due to variation in the nature and severity of a patient’s illness, unexpected complications in a patient’s course of treatment and the arrival of non-scheduled emergency patients which compete for resources. Extend simulation software was used for its ability to represent highly complex systems and analyse model outputs. Patient arrivals and lengths of surgery are determined by analysis of historical data. The model was used to explore the effects increasing patient arrivals and alternative elective patient admission disciplines would have on the performance measures. The model can be used as a decision support system for hospital planners.

It is important to understand how student performance when higher education is delivered by via new technology. Podcasting is a relatively recent new technology gaining widespread use across the world. We present the results of a quasi-experimental research project that finds when podcasts are used as a revision tool, student performance in Accounting improves. We highlight that aligning podcast use with pedagological design is important and discuss constraints on and barriers to the use of podcasting in higher education.

The enhanced social profile of not-for-profit organisations (NFPs) and the role of volunteers have resulted in calls for NFPs to be more accountable and to disclose information relating to such contributions. In this study we identify, locate and categorise the extent of disclosures made in relation to volunteer contributions. We find that disclosure was more prevalent on NFP websites compared to digital annual report disclosures. We find that more NFPs provided disclosure on the activities of their volunteers than other items pertaining to volunteers. The valuation of volunteer contributions was the least likely to be disclosed. The findings contribute to international debate over the inclusion of volunteer contributions in the assessment of a NFP’s accountability over its resources and ultimately the enhancement of its sustainability.

This exhibition and catalogue provides a visual record of student work exhibited at the Australian Institute of Architects offices in Brisbane from November 15 to 29, 2010. The exhibition features the final design outcomes of the inaugural Bushfire Sustainability unit conducted at QUT in semester two, 2010. The core objective of this unit was to develop our students’ skills in collaborative practice in design, research and presentation. The theme of ‘bushfire sustainability’ was chosen because living sustainably in bushfire prone landscapes presents a number of problems, the nature of which might only be resolved via multidisciplinary collaboration among the design disciplines. The students involved represent the disciplines of Interior Design, Landscape Architecture, Industrial Design, Architecture and Sustainability – all from within the School of Design at QUT. 55 students, mostly in their third year of study, worked in teams of five (one from each discipline) to design one of a number of homes in highly bushfire prone sites in either Western Australia or SE Queensland. This year level and the interdisciplinary mix are perhaps the best placed to resolve these problems: being unrestrained from the burdens of professional practice and technical overload they retain the potential for innovative, lateral thinking across the range of spatial scales and philosophical perspectives associated with inhabitation of bushfire prone landscapes. It is envisaged that, through the ‘vehicle’ of this design research, that the students’ work will contribute to understandings of how creative design disciplines might respond to this significant national problem, which hitherto has been attended to primarily by engineering and the sciences.

The presence of calcium hydroxide (Ca(OH)2) in Bayer residue slurry inhibits the effectiveness of the seawater neutralisation process to reduce the pH and aluminium concentration in the residue. An increase in the slurry pH (reversion), after seawater neutralisation, is caused by the dissolution of calcium hydroxide and hydrocalumite (solid components found in bauxite refinery residue). Reversion was not observed when the final solution pH was greater than 10.5, due to hydrocalumite being in a state of equilibrium at high pH. Hydrocalumite has been found to form during the neutralisation process when high concentrations of calcium hydroxide are present in the residue liquor. The dissolution of hydrocalumite releases hydroxyl (OH-) and aluminium ions back into solution after the seawater neutralisation (SWN) process, which causes pH and aluminium reversion to occur. This investigation looks at the effect of Ca(OH)2 and subsequently hydrocalumite on the pH and aluminium concentration in bauxite refinery residue liquors after the SWN process.
