Adaption and use of a compressible flow code for turbomachinery design

The present paper presents and discusses the use of dierent codes regarding the numerical simulation of a radial-in ow turbine. A radial-in ow turbine test case was selected from published literature [1] and commercial codes (Fluent and CFX) were used to perform the steady-state numerical simulations. An in-house compressible- ow simulation code, Eilmer3 [2] was also adapted in order to make it suitable to perform turbomachinery simulations and preliminary results are presented and discussed. The code itself as well as its adaptation, comprising the addition of terms for the rotating frame of reference, programmable boundary conditions for periodic boundaries and a mixing plane interface between the rotating and non-rotating blocks are also discussed. Several cases with dierent orders of complexity in terms of geometry were considered and the results were compared across the dierent codes. The agreement between these results and published data is also discussed.

The naming of waterfalls

As features of the landscape, waterfalls have been studied extensively by geographers, but the names given to these landforms have received relatively little scholarly attention. This paper examines the naming of waterfalls and addresses the question of classifying these hydronyms. The subject is considered in a global historical context, focusing on place names in the anglophone world. Until the 18th and 19th centuries, relatively few waterfalls were named.With the beginning of the Industrial Revolution, water power rose in economic importance, and at the same time, there was a growing scientific and aesthetic engagement with the landscape. These developments are suggested as reasons for the increased interest in waterfalls which were then being recorded in topographical literature and on maps, individual names being given to increasing numbers of falls. European exploration added to the knowledge of the world’s waterfalls, many of which were given names by their ‘discoverers’. This naming process accelerated with the growth of domestic and overseas tourism which exploited scenic resources such as waterfalls. Until now, research on the names of waterfalls has been fragmentary, and the classification of these hydronyms has been neglected. This paper demonstrates that waterfall names can be classified in accordance with a recognised toponymic typology. Using examples drawn from waterfall guidebooks, databases, maps, and other sources, the following discussion supports George Stewart’s claim that his toponymic classification is valid for place names of all kinds.

Towards Asia literacy : the Australian curriculum and Asian-Australian children's literature

This paper is concerned with the ways Asia Literacy can be developed in response to the new Australian Curriculum. In particular, it addresses the learning possibilities of the Asian-Australian Literature and Publishing Project (AACLAP) available through AustLit: the Australian Literature Resource. The paper argues that the AACLAP dataset provides a broad range of resources through which to address the cross curriculum priority of the Australian Curriculum on Asia and Australia’s engagement with Asia. It contends that AACLAP has the potential to make a valuable contribution to teachers’ efforts to incorporate this cross curriculum priority in their classroom practice whilst also developing the general capabilities of intercultural understanding and the use of information and communication technology (ICT). This discussion is of particular significance to teachers of English and History, given that these disciplines are implemented in the first phase of the Australian Curriculum in schools. The paper concludes that by drawing on the broad range of texts available in the AACLAP collection as well as the Critical Anthology and the Research and Learning Trails, teachers and students will be much better positioned to develop a deeper understanding of the diversity of the Asian region and the complexities of Asian-Australian relationships.

Digital archives and cultural memory : discovering lost histories in digitised Australian children's literature 1851-1945

A recent Australian literature digitisation project uncovered some surprising discoveries in the children’s books that it digitised. The Children’s Literature Digital Resources (CLDR) Project digitised children’s books that were first published between 1851 to 1945 and made them available online through AustLit: The Australian Literature Resource. The digitisation process also preserved, within the pages of those books, a range of bookplates, book labels, inscriptions, and loose ephemera. This material allows us to trace the provenance of some of the digitised works, some of which came from the personal libraries of now-famous authors, and others from less celebrated sources. These extra-textual traces can contribute to cultural memory of the past by providing evidence of how books were collected and exchanged, and what kinds of books were presented as prizes in schools and Sunday schools. They also provide insight into Australian literary and artistic networks, particularly of the first few decades of the 20th century. This article describes the kinds of material uncovered in the digitisation process and suggests that the material provides insights into literary and cultural histories that might otherwise be forgotten. It also argues that the indexing of this material is vital if it is not to be lost to future researchers.

Preserving the past in digital memory

The process of researching children’s literature from the past is a growing challenge as resources age and are increasingly treated as rare items, stored away within libraries and other research centres. In Australia, researchers and librarians have collaborated with the bibliographic database AustLit: The Australian Literature Resource to produce the Australian Children’s Literature Digital Resources Project (CLDR). This Project aims to address the growing demand for online access to rare children’s literature resources, and demonstrates the research potential of early Australian children’s literature by supplementing the collection with relevant critical articles. The CLDR project is designed with a specific focus and provides access to full text Australian children’s literature from European settlement to 1945. The collection demonstrates a need and desire to preserve literature treasures to prevent losing such collections in a digital age. The collection covers many themes relevant to the conference including, trauma, survival, memory, survival, hauntings, and histories. The resource provides new and exciting ways with which to research children’s literature from the past and offers a fascinating repository to scholars and professionals of ranging disciplines who are in interested in Australian children’s literature.

The role of knowledge intermediaries in developing firm learning capabilities

Regional innovation systems (RISs) literature has emphasized the critical role of interactive learning and knowledge exchange amongst firms and a variety of spatially connected innovation institutions as the foundation of regional innovation. Knowledge intermediaries have been analysed in terms of the technology-transaction services they provide firms and/or knowledge producers such as universities and therefore the role they play in facilitating interaction within the RIS. However, innovation also depends on the capability of the firm to learn. Some studies have suggested that intermediaries also play a role in that regard as participation in intermediary knowledge transfer programmes can contribute to the development of firm capabilities for problem-solving and learning. Our research is based on two case study intermediary programmes involving interviews with facilitators and participants. Our data show that knowledge intermediaries affect organizational learning capabilities by impacting on firms' network relationships, internal and external communication channels and internal learning processes which in turn affect the ability to interpret and use knowledge within the firm. This suggests that the role of knowledge intermediaries might be greater than facilitating interactions in the innovation system, as knowledge intermediation may affect the ability of firms to learn and absorb knowledge from their environment.

What makes an LMS effective : a synthesis of current literature

There is a growing number of organizations and universities now utilising e-learning practices in their teaching and learning programs. These systems have allowed for knowledge sharing and provide opportunities for users to have access to learning materials regardless of time and place. However, while the uptake of these systems is quite high, there is little research into the effectiveness of such systems, particularly in higher education. This paper investigates the methods that are used to study the effectiveness of e-learning systems and the factors that are critical for the success of a learning management system (LMS). Five major success categories are identified in this study and explained in depth. These are the teacher, student, LMS design, learning materials and external support.

Creativity is as important as literacy : making a film trailer responding to literature

The first part of the title is from Sir Ken Robinson (Robinson, 2009), the esteemed educator and champion of creativity in schools. Sometimes in the face of meeting the demands of time, timetabling, demanding administration tasks and teaching for high stakes testing accountability, we can find ourselves desperate for time to remember that English has always been one of the places in schools where creativity can flourish. English is a place for the play of the imagination. English teachers are the purveyors of narrative; the keepers and teachers of stories. The new Australian Curriculum: English, (Australian Curriculum and Assessment Reporting Authority (ACARA), 2012) asks us to be using ICT technologies in creative ways to tell those stories. The curriculum asks students to access texts receptively and to then speak about, write and create texts productively. There are so many interesting things to do with texts beyond word processing of print based resources. Responding to literature through media is always an alternative option to writing or simply speaking about it. In this paper my QUT pre-service student Chrystal Armitage describes how she made a mini story via a film trailer in response to a short story, ‘Turned’ (Gilman, 1987) in the unit, Literature in Secondary Teaching.

Human rights, the law, cyber-security and democracy : after the European Convention

Many commentators have treated the internet as a site of democratic freedom and as a new kind of public sphere. While there are good reasons for optimism, like any social space digital space also has its dark side. Citizens and governments alike have expressed anxiety about cybercrime and cyber-security. In August 2011, the Australian government introduced legislation to give effect to Australia becoming a signatory to the European Convention on Cybercrime (2001). At the time of writing, that legislation is still before the Parliament. In this article, attention is given to how the legal and policy-making process enabling Australia to be compliant with the European Convention on Cybercrime came about. Among the motivations that informed both the development of the Convention in Europe and then the Australian exercise of legislating for compliance with it was a range of legitimate concerns about the impact that cybercrime can have on individuals and communities. This article makes the case that equal attention also needs to be given to ensuring that legislators and policy makers differentiate between legitimate security imperatives and any over-reach evident in the implementation of this legislation that affects rule of law principles, our capacity to engage in democratic practices, and our civic and human rights.

Symptom burden in chronic kidney disease : a review of recent literature

Background: People living with chronic kidney disease (CKD) experience multiple symptoms due to both the disease and its treatment, these symptoms are often under recognized. The majority of studies have focused on an individual symptom; however these symptoms rarely occur in isolation and may instead occur in clusters. Aim of review: This review investigated the total symptom burden in advanced CKD (stages 4 and 5) and identified the key instruments that are used to assess multiple symptoms. Methods: A literature search from 2006 to 2012 was undertaken and a total of 19 articles were included. Result: The most common CKD symptoms were fatigue or lack of energy, feeling drowsy, pain and pruritus. However, symptom assessment instruments varied between studies, often with inconsistent or inadequate symptom dimensions. Conclusion: People with CKD experience a high burden of symptom, although little is known about the burden for people with CKD stage 4 and for those with CKD stage 5 receiving PD. This review recommends that a full range of symptoms be assessed for those at different stages of CKD. Improved understanding of the burden of symptoms could be used as the basis for treatment choices and for identifying priorities which are likely to contribute to a better quality of life and improve the quality of care.

The effectiveness of energy feedback for conservation and peak demand : a literature review

This paper reviews electricity consumption feedback literature to explore the potential of electricity feedback to affect residential consumers’ electricity usage patterns. The review highlights a substantial amount of literature covering the debate over the effectiveness of different feedback criteria to residential customer acceptance and overall conservation and peak demand reduction. Researchers studying the effects of feedback on everyday energy use have observed substantial variation in effect size, both within and between studies. Although researchers still continue to question the types of feedback that are most effective in encouraging conservation and peak load reduction, some trends have emerged. These include that feedback be received as quickly as possible to the time of consumption; be related to a standard; be clear and meaningful and where possible both direct and indirect feedback be customised to the customer. In general, the literature finds that feedback can reduce electricity consumption in homes by 5 to 20 per cent, but that significant gaps remain in our knowledge of the effectiveness and cost benefit of feedback.

Modeling destination brand equity in an emerging long haul market

The destination branding literature emerged as recently as 1998, and there remains a dearth of empirical data that tests the effectiveness of brand campaigns over time. This paper reports the results of an investigation into consumer-based brand equity for Australia as a long haul destination in an emerging South American market. In spite of the high level of academic interest in the measurement of perceptions of destinations since the 1970s, few previous studies have examined perceptions held by South American consumers. Findings suggest that destination brand awareness, brand image, and brand value are positively related to brand loyalty for a long-haul destination. The results also indicate that Australia is a more compelling destination brand for previous visitors compared to non-visitors.

Retention and graduation of Aboriginal and Torres Strait Islander students in initial teacher education : a review of the literature

While the need to increase numbers of Indigenous teachers has been highlighted for many years, Aboriginal and Torres Strait Islander teachers are still significantly underrepresented in Australia making up less that 1% of teachers in schools. Nationally, little has changed since the 1980s when Hughes and Wilmot (1992) called for ‘1000 Indigenous teachers by 1990’. This paper reports on an initial literature review of teacher education as related to the preparation of Aboriginal and Torres Strait Islanders. Alongside the scholarly literature, the review to date includes analysis of over twenty policy documents and government reports as well as web-based descriptions of historical and current models of Indigenous teacher education including both mainstream Education programs and cohort-based and community models. While the literature provides examples of successful models of Indigenous teacher education it also illuminates the longstanding and interrelated factors that continue to impact on the success or failure of teacher education for Aboriginal and Torres Strait Islanders
