Sitooter-i

As part of the process of renewing its City Centre Master Plan, Brisbane City Council and its CBD are hosting an Ideas Fiesta between April 11th- 3rd May 2013. It hopes to generate new ideas, showcase design concepts, and stimulate interest in imagining the future of the city centre. Events will be held in a variety of city outdoor spaces, streets, laneways and venues to identify catalyst projects and explore design ideas for the city centre. In the City Botanic Gardens ‘Sunday reserved for you’ on 21st April and ‘A shot of green’ on Wednesday 24th April are some of the events planned and are the setting for innovative items of park furniture and other activities. A sitooterie (Scottish) is an outdoor space to sit… a place to enjoy nature. This Sitooter-i has been digitally designed for CNC fabrication with the ergonomics of reclining, lounging, just sitting or jumping around in mind. It was assembled by staff and students from Queensland University of Technology and is made from locally sourced plywood components which are easily dismantled for re-use elsewhere. But this Sitooter-i inspired by natural forms is also both physically and technologically interactive. Sensors record sound, light and temperature in their interactions with users. This data may be relayed as LED lights played in rhythm along frame edges or used by Brisbane City Council to assess frequency and style of use, perhaps revealing the effectiveness of its performance and the preferences of its users.

Little boxes : changing perceptions and including young people in socially sustainable participatory planning

In recent years, a great deal has been written about the benefits and ethics of including young people in participative decision-making. This has been accompanied by a burgeoning interest in including their views in participatory planning exercises that has not always been realised in practice. Drawing on a detailed analysis of the perceptions of adults and young people involved in a participatory planning exercise on Australia‟s Gold Coast, we believe that there are two major hurdles to the „full‟ engagement of young people that are in some respects two sides of the same coin: the sometimes paternalistic perceptions and often dismissive attitude that many adults have towards the participation of young people; and the perceptions that young people may have of themselves and their subordinate place in an adult-dominated planning environment. Together, such views act to place limitations on the participation of young people because they set up unrealistic expectations for both adult and younger participants in terms of how and why young people participate, and what this participation should „look and feel‟ like. In this paper, through the metaphor of boxes, we propose a number of issues that should be addressed when involving young people in participatory planning processes to ensure the most from their participation for all involved.

Building a community of learners within the STEM higher education classroom

Building rich and authentic learning experiences in the STEM classroom, is a challenge for many educators within Higher Education. While many Higher Education Institutions have embraced the need to transform current teaching and learning practices and include a range of online tools, this has often been met with some resistance and approaches that do not always recognise the academic who are a critical component to the success of the transformational process. Over the last decade the Internet has evolved from being a tool used by a few dedicated educators to one that is being used by the majority of educators. However, what is important is how this great resource is used in teaching and learning to allow students to build knowledge. The ability for students to construct knowledge and engage in higher order thinking skills is at the heart of educational practices, and building a community of learners has the potential to support these practices, especially within STEM education. This paper explores the relationship between students and an academic teaching in a technology rich STEM learning environment and their adoption of social community and shared tools. In particular the paper reports on the critical components that make a successful community of learners and the educational tools and approaches that were successfully used to enhance the student learning experience in a STEM classroom.

Making optimal and justifiable asset maintenance decisions

Maintenance decisions for large-scale asset systems are often beyond an asset manager's capacity to handle. The presence of a number of possibly conflicting decision criteria, the large number of possible maintenance policies, and the reality of budget constraints often produce complex problems, where the underlying trade-offs are not apparent to the asset manager. This paper presents the decision support tool "JOB" (Justification and Optimisation of Budgets), which has been designed to help asset managers of large systems assess, select, interpret and optimise the effects of their maintenance policies in the presence of limited budgets. This decision support capability is realized through an efficient, scalable backtracking- based algorithm for the optimisation of maintenance policies, while enabling the user to view a number of solutions near this optimum and explore tradeoffs with other decision criteria. To assist the asset manager in selecting between various policies, JOB also provides the capability of Multiple Criteria Decision Making. In this paper, the JOB tool is presented and its applicability for the maintenance of a complex power plant system.

Pipeline renewal decision support : a case study using LinEAR in a water pipeline network

This paper presents a case study for the application of a Linear Engineering Asset Renewal decision support software tool (LinEAR) at a water distribution network in Australia. This case study examines how the LinEAR can assist water utilities to minimise their total pipeline management cost, to make a long-term budget based on mathematically predicted expenditure, and to present calculated evidence for supporting their expenditure requirements. The outcomes from the study on pipeline renewal decision support demonstrate that LinEAR can help water utilities to improve the decision process and save renewal costs over a long-term by providing an optimum renewal schedules. This software can help organisation to accumulate technical knowledge and prediction future impact of the decision using what-if analysis.

Why have a governing body?

In this chapter we aim to provide a 'pracademic' view on the reasons why we have boards and why they undertake certain activities. Our approach is based primarily on academic research, hopefully tempered with a real-world understanding of governance issues. We also rely on insights we have gleaned from our own research that primarily relies on observing boards in action.

The ACNC's new governance rules

Australian charities have a new regulator in the form of the Australian Charities and Not-for-profits Commission (ACNC) which began operations in December 2012; and new governance rules which applied from 1 July 2013. While there is some uncertainty over the ACNC's future, the new legislative framework currently applies to approximately 58,000 charities which seek federal tax concessions and other benefits, and includes governance standards that apply across charitable organisational forms (company, trust and association) with some exceptions. The governance standards are a minimum benchmark that many charities will already meet, if they are companies or incorporated associations.

Roundabout design and cycling safety

Roundabouts reduce the frequency and severity of motor vehicle crashes and therefore the number installed has increased dramatically in the last 20 years in many countries. However, the safety impacts of roundabouts for bicycle riders are a source of concern, with many studies reporting lower injury reductions for cyclists than car occupants. This paper summarises the results of a project undertaken to provide guidance on how cyclist safety could be improved at existing roundabouts in Queensland, Australia, where cyclist crashes have been increasing and legislation gives motor vehicles priority over cyclists and pedestrians at roundabouts. The review of international roundabout design guidelines identified two schools of design: tangential roundabouts (common in English-speaking countries, including Australia), which focus on minimising delay to motor vehicles, and radial roundabouts (common in continental Europe), which focus on speed reduction and safety. While it might be expected that radial roundabouts would be safer for cyclists, there have been no studies to confirm this view. Most guidelines expect cyclists to act as vehicle traffic in single-lane, typically low-speed, roundabouts. Some jurisdictions do not permit cyclists to travel on multi-lane roundabouts, and recommend segregated bicycle facilities because of their lowest crash risk for cyclists. Given that most bicycle-vehicle crashes at roundabouts involve an entering vehicle and a circulating cyclist, the greatest challenges appear to be reducing the speed of motor vehicles on the approach/entry to roundabouts and other ways of maximizing the likelihood that cyclists will be seen. Lower entry speeds are likely to underpin the greater safety of compact roundabouts for cyclists and, conversely, the higher than expected crash rates at two-lane roundabouts. European research discourages the use of bike lanes in roundabouts which position cyclists at the edge of the road and contributes to cyclists being less likely to be noticed by drivers.

Consumer phase identification in a three phase unbalanced LV distribution network

A new technique is presented for automatically identifying the phase connection of domestic customers. Voltage information from a reference three phase house is correlated with voltage information from other customer electricity meters on the same network to determine the highest probability phase connection. The techniques are purely based upon a time series of electrical voltage measurements taken by the household smart meters and no additional equipment is required. The method is demonstrated using real smart meter datasets to correctly identify the phase connections of 75 consumers on a low voltage distribution feeder.

Understanding welding practices on shipyards : an ethnographic study for designing an interactive robot welder

The aim of this ethnographic study was to understand welding practices in shipyard environments with the purpose of designing an interactive welding robot that can help workers with their daily job. The robot is meant to be deployed for automatic welding on jack-up rig structures. The design of the robot turns out to be a challenging task due to several problematic working conditions on the shipyard, such as dust, irregular floor, high temperature, wind variations, elevated working platforms, narrow spaces, and circular welding paths requiring a robotic arm with more than 6 degrees of freedom. Additionally, the environment is very noisy and the workers – mostly foreigners – have a very basic level of English. These two issues need to be taken into account when designing the interactive user interface for the robot. Ideally, the communication flow between the two parties involved should be as frictionless as possible. The paper presents the results of our field observations and welders’ interviews, as well as our robot design recommendation for the next project stage.

The burden attributable to mental and substance use disorders as risk factors for suicide : findings from the Global Burden of Disease Study 2010

Background The Global Burden of Disease Study 2010 (GBD 2010) identified mental and substance use disorders as the 5th leading contributor of burden in 2010, measured by disability adjusted life years (DALYs). This estimate was incomplete as it excluded burden resulting from the increased risk of suicide captured elsewhere in GBD 2010's mutually exclusive list of diseases and injuries. Here, we estimate suicide DALYs attributable to mental and substance use disorders. Methods Relative-risk estimates of suicide due to mental and substance use disorders and the global prevalence of each disorder were used to estimate population attributable fractions. These were adjusted for global differences in the proportion of suicide due to mental and substance use disorders compared to other causes then multiplied by suicide DALYs reported in GBD 2010 to estimate attributable DALYs (with 95% uncertainty). Results Mental and substance use disorders were responsible for 22.5 million (14.8-29.8 million) of the 36.2 million (26.5-44.3 million) DALYs allocated to suicide in 2010. Depression was responsible for the largest proportion of suicide DALYs (46.1% (28.0%-60.8%)) and anorexia nervosa the lowest (0.2% (0.02%-0.5%)). DALYs occurred throughout the lifespan, with the largest proportion found in Eastern Europe and Asia, and males aged 20-30 years. The inclusion of attributable suicide DALYs would have increased the overall burden of mental and substance use disorders (assigned to them in GBD 2010 as a direct cause) from 7.4% (6.2%-8.6%) to 8.3% (7.1%-9.6%) of global DALYs, and would have changed the global ranking from 5th to 3rd leading cause of burden. Conclusions Capturing the suicide burden attributable to mental and substance use disorders allows for more accurate estimates of burden. More consideration needs to be given to interventions targeted to populations with, or at risk for, mental and substance use disorders as an effective strategy for suicide prevention.
