Computer planning of stereotactic iodine-125 seed brachytherapy for recurrent malignant gliomas

At St Thomas' Hospital, we have developed a computer program on a Titan graphics supercomputer to plan the stereotactic implantation of iodine-125 seeds for the palliative treatment of recurrent malignant gliomas. Use of the Gill-Thomas-Cosman relocatable frame allows planning and surgery to be carried out at different hospitals on different days. Stereotactic computed tomography (CT) and positron emission tomography (PET) scans are performed and the images transferred to the planning computer. The head, tumour and frame fiducials are outlined on the relevant images, and a three-dimensional model generated. Structures which could interfere with the surgery or radiotherapy, such as major vessels, shunt tubing etc., can also be outlined and included in the display. Catheter target and entry points are set using a three-dimensional cursor controlled by a set of dials attached to the computer. The program calculates and displays the radiation dose distribution within the target volume for various catheter and seed arrangements. The CT co-ordinates of the fiducial rods are used to convert catheter co-ordinates from CT space to frame space and to calculate the catheter insertion angles and depths. The surgically implanted catheters are after-loaded the next day and the seeds left in place for between 4 and 6 days, giving a nominal dose of 50 Gy to the edge of the target volume. 25 patients have been treated so far.

Wind-energy based path planning for electric unmanned aerial vehicles using Markov Decision Processes

Exploiting wind-energy is one possible way to ex- tend flight duration for Unmanned Arial Vehicles. Wind-energy can also be used to minimise energy consumption for a planned path. In this paper, we consider uncertain time-varying wind fields and plan a path through them. A Gaussian distribution is used to determine uncertainty in the Time-varying wind fields. We use Markov Decision Process to plan a path based upon the uncertainty of Gaussian distribution. Simulation results that compare the direct line of flight between start and target point and our planned path for energy consumption and time of travel are presented. The result is a robust path using the most visited cell while sampling the Gaussian distribution of the wind field in each cell.

Teaching undergraduate students community nursing : using action research to increase engagement and learning

Nurses play a pivotal role in responding to the changing needs of community health care. Therefore, nursing education must be relevant, responsive, and evidence based. We report a case study of curriculum development in a community nursing unit embedded within an undergraduate nursing degree. We used action research to develop, deliver, evaluate, and redesign the curriculum. Feedback was obtained through self-reflection, expert opinion from community stakeholders, formal student evaluation, and critical review. Changes made, especially in curriculum delivery, led to improved learner focus and more clearly linked theory and practice. The redesigned unit improved performance, measured with the university's student evaluation of feedback instrument (increased from 0.3 to 0.5 points below to 0.1 to 0.5 points above faculty mean in all domains), and was well received by teaching staff. The process confirmed that improved pedagogy can increase student engagement with content and perception of a unit as relevant to future practice.

Rebuilding housing after a disaster : factors for failure

Disasters, particularly those triggered by nature are often followed by a swift humanitarian relief response to address the resultant emergencies. These efforts are then transitioned through the medium recovery stage, eventually aimed at providing a long term post-disaster reconstruction solution. Emergency humanitarian relief focuses on responding to the immediate need for restoration of basic services, medical treatment and medical supplies, food and temporary shelter, and is a short term strenuous effort. Reconstruction of permanent houses, on the other hand, is a continuous process that often requires decades of effort to return a community to normality. Whilst emergency relief is generally perceived to be very effective, post-disaster housing reconstruction projects often fail to meet their set objectives. This paper outlines and discusses factors that contribute to the failure of post-disaster housing reconstruction projects and the subsequent immediate and long term negative impacts of failure on project outcomes.

The impact of the GST on the community services sector in Queensland

The impact of the GST has on nonprofit organisations has been largely ignored in the compliance cost literature. Most studies to date, both in Australia and overseas, have focused exclusively on measuring the nature and extent of GST compliance costs of businesses in the for-profit sector (particularly the impact on small businesses). This paper examines the impact of The New Tax System, and in particular, the GST on Queensland community sector organisations. The results are extracted from a QCOSS report entitled “Taxing Goodwill: The Impact of GST on Community Services” released in October 2001.

People, content, location : sweet spotting urban screens for situated engagement

A growing body of research is looking at ways to bring the processes and benefits of online deliberation to the places they are about and in turn allow a larger, targeted proportion of the urban public to have a voice, be heard, and engage in questions of city planning and design. Seeking to take advantage of the civic opportunities of situated engagement through public screens and mobile devices, our research informed a public urban screen content application DIS that we deployed and evaluated in a wide range of real world public and urban environments. For example, it is currently running on the renowned urban screen at Federation Square in Melbourne. We analysed the data from these user studies within a conceptual framework that positions situated engagement across three key parameters: people, content, and location. We propose a way to identify the sweet spot within the nexus of these parameters to help deploy and run interactive systems to maximise the quality of the situated engagement for civic and related deliberation purposes.

Beyond broadcasting: customer service, community and information experience in the Twittersphere

What opportunities does a channel like Twitter offer to libraries, beyond the realm of marketing? We would like to highlight three roles for Twitter in the academic library environment: Twitter as a service delivery and service recovery channel; Twitter as a community builder; Twitter as a site for information experience.

Creating successful cultural Brokers : the pros and cons of a community of practice approach in arts management education

Arts managers play a critical role in creating a strong, sustainable arts and cultural sector. They operate as brokers, creating programs, and, more critically, coordinating the relationships between artists, audiences, communities, governments and sponsors required to make these programs a success. Based on study of model developed for a subject in the Master of Creative Industries (Creative Production & Arts Management) at Queensland University of Technology (QUT), this paper examines the pros and cons of a “community of practice” approach in training arts management students to act as cultural brokers. It provides data on the effectiveness of a range of activities – including Position Papers, Case Studies, Masterclasses, and offline and online conversations – that can be used facilitate the peer-to-peer engagement by which students work together to build their cultural brokering skills in a community of practice. The data demonstrates that, whilst students appreciate this approach, educators must provide enough access to voices of authority – that is, to arts professionals – to establish a well-functioning community of practice, and ensure that more expert students do not become frustrated when they are unwittingly and unwillingly thrust into this role by less expert classmates. This is especially important in arts management, where classes are always diverse, due to the fact that most dedicated programs in Australia, as in the US, UK and Europe, are taught via small-scale programs at graduate level which accept applicants from a wide variety of arts and non-arts backgrounds.

Reconciling community and commerce? Collaboration between produsage communities and commercial operators

Collaborative user-led content creation by online communities, or produsage (Bruns 2008), has generated a variety of useful and important resources and other valuable outcomes, from open source software through the Wikipedia to a variety of smaller-scale, specialist projects. These are often seen as standing in an inherent opposition to commercial interests, and attempts to develop collaborations between community content creators and commercial partners have had mixed success rates to date. However, such tension between community and commerce is not inevitable, and there is substantial potential for more fruitful exchanges and collaboration. This article contributes to the development of this understanding by outlining the key underlying principles of such participatory community processes and exploring the potential tensions which could arise between these communities and their potential external partners. It also sketches out potential approaches to resolving them.

Mathematics funds of knowledge : sotmaute and sermaute fish in a Torres Strait Islander community

The purpose of this article is to describe a project with one Torres Strait Islander Community. It provides some insights into parents’ funds of knowledge that are mathematical in nature, such as sorting shells and giving fish. The idea of funds of knowledge is based on the premise that people are competent and have knowledge that has been historically and culturally accumulated into a body of knowledge and skills essential for their functioning and well-being. This knowledge is then practised throughout their lives and passed onto the next generation of children. Through adopting a community research approach, funds of knowledge that can be used to validate the community’s identities as knowledgeable people, can also be used as foundations for future learnings for teachers, parents and children in the early years of school. They can be the bridge that joins a community’s funds of knowledge with schools validating that knowledge.

A cross-cultural approach towards designing digital noticeboards with a remote aboriginal community

This working paper reflects upon the opportunities and challenges of designing a form of digital noticeboard system with a remote Aboriginal community that supports their aspirations for both internal and external communication. The project itself has evolved from a relationship built through ecological work between scientists and the local community on the Groote Eylandt archipelago to study native populations of animal species over the long term. In the course of this work the aspiration has emerged to explore how digital noticeboards might support communication on the island and externally. This paper introduces the community, the context and the history of the project. We then reflect upon the science project, its outcomes and a framework empowering the Aboriginal viewpoint, in order to draw lessons for extending what we see as a pragmatic and relationship based approach towards cross-cultural design.

Towards designing digital noticeboards with a remote indigenous community

This position paper reflects upon the opportunities and challenges of designing a digital noticeboard system with a remote indigenous community that supports their aspirations for both internal and external communication. The project itself has evolved from a relationship built through ecological work between scientists and the local community on the Groote Eylandt archipelago to study native populations of animal species over the long term. In the course of this work the aspiration has emerged to explore how digital noticeboards might promote and communicate aspects of work and life on the island through both the web and touchscreen noticeboards. This paper introduces the community, the context and the history of the project. We then reflect upon the science project and its outcomes, in order to draw lessons for extending what we see as a pragmatic and relationship based approach towards design.

Training the public to collect oral histories of our community : the OHAA Queensland Chapter’s model

In a digital age, the skills required to undertake an oral history project have changed dramatically. For community groups, this shift can be new and exciting, but can also invoke feelings of anxiety when there is a gap in the skill set. Addressing this gap is one of Oral History Association of Australia, Queensland (OHAA Qld) main activities. This paper reports on the OHAA Qld chapter’s oral history workshop program, which was radically altered in 2011.

Best practice business community partnerships

In the last two years or so, the Prime Minister has made the development of a social coalition, involving business partnerships with the community, central to his Government’s vision of a fair and just Australian society. This is clearly a new and exciting era in thinking for government, business and community partnerships. However, there has been a tendency, particularly in the media reporting of these initiatives, especially the Prime Minister's Business Community Partnership awards held in 1999 and in July this year, to concentrate the agenda more on philanthropy and corporate donations, than on some of the many other ways that partnerships can develop...

Valuing diversity : a multiliteracies project in a remote Indigenous community

This chapter draws attention to the complex nature of teachers’ work when working with linguistically and culturally diverse students and their communities in an era of new literacies. One multiliteracies project undertaken within a remote Indigenous community in the Torres Straits, Far North Queensland, Australia, is presented. The discussion considers understandings of student diversity as articulated in the Australian Curriculum documents, designs of meaning for written and visual text and the various components of pedagogy introduced into a multiliteracies project. The chapter concludes by highlighting the usefulness of the ‘wide, but not vague’ multiliteracies approach and the importance of an explicit grammar for written and visual text, for meeting the literacy learning needs of one group of 21st century learners.
