Developing financial decision support for highway infrastructure sustainability

The development of highway infrastructure typically requires major capital input over a long period. This often causes serious financial constraints for investors. The push for sustainability has added new dimensions to the complexity in the evaluation of highway projects, particularly on the cost front. This makes the determination of long-term viability even more a precarious exercise. Life-cycle costing analysis (LCCA) is generally recognised as a valuable tool for the assessment of financial decisions on construction works. However to date, existing LCCA models are deficient in dealing with sustainability factors, particularly for infrastructure projects due to their inherent focus on the economic issues alone. This research probed into the major challenges of implementing sustainability in highway infrastructure development in terms of financial concerns and obligations. Using results of research through literature review, questionnaire survey of industry stakeholders and semi-structured interview of senior practitioners involved in highway infrastructure development, the research identified the relative importance of cost components relating to sustainability measures and on such basis, developed ways of improving existing LCCA models to incorporate sustainability commitments into long-term financial management. On such a platform, a decision support model incorporated Fuzzy Analytical Hierarchy Process and LCCA for the evaluation of the specific cost components most concerned by infrastructure stakeholders. Two real highway infrastructure projects in Australia were then used for testing, application and validation, before the decision support model was finalised. Improved industry understanding and tools such as the developed model will lead to positive sustainability deliverables while ensuring financial viability over the lifecycle of highway infrastructure projects.

Using incomplete online metric maps for topological exploration with the Gap Navigation Tree

This paper presents a general, global approach to the problem of robot exploration, utilizing a topological data structure to guide an underlying Simultaneous Localization and Mapping (SLAM) process. A Gap Navigation Tree (GNT) is used to motivate global target selection and occluded regions of the environment (called “gaps”) are tracked probabilistically. The process of map construction and the motion of the vehicle alters both the shape and location of these regions. The use of online mapping is shown to reduce the difficulties in implementing the GNT.

Bariatric patients and the use of mobile hoists : user experiences from three hospitals in South Australia

Nursing personnel are consistently identified as one of the occupational groups most at risk of work-related musculoskeletal disorders. During the moving and handling of bariatric patients, the weight of the patient combined with atypical body mass contributes to a significant risk of injury to the care provider and patient. This is further compounded by the shape, mobility and co-operation of the patient. The aim of this study was determine user experiences and design requirements for mobile hoists with bariatric patients. Structured interviews were conducted with six experienced injury management staff from the Manual Task Services department of three hospitals in Adelaide, South Australia. All staff had experience in patient handling, the use of patient handling equipment and the provision of patient handling training. A series of open-ended questions were structured around five main themes: 1) patient factors; 2) building/vehicle space and design; 3) equipment and furniture; 4) communication; and 5) staff issues. Questions focussed on the use of mobile hoists for lifting and transferring bariatric patients. Interviews were supplemented with a walk-through of the hospital to view the types of mobile hoists used, and the location and storage of equipment. Across the three hospitals there were differing classification systems to define bariatric patients. Ensuring patient dignity, respect and privacy were viewed as important in the management and rehabilitation of bariatric patients. Storage and space constraints were considered factors restricting the use of mobile floor hoists, with ceiling hoists being the preferred method for patient transfers. When using mobile floor hoists, the forces required to push, pull and manoeuvre, as well as sudden unstable movements of the hoist were considered important risks factors giving rise to a risk of injury to the care provider. Record keeping and purchasing policies appeared to inhibit the effective use of patient handling equipment. The moving and handling of bariatric patients presents complex and challenging issues. A co-ordinated and collaborative approach for moving and handling bariatric patients is needed across the range of care providers. Designers must consider both user and patient requirements.

Book Review: "Mark Considine, Jenny Lewis and Damon Alexander Networks, Innovation and Public Policy : Politicians, Bureaucrats and the Pathways to Change inside Government Houndsmills, UK: Palgrave Macmillan, 2009"

Having wrung the most from workforce and workplace productivity initiaitves, innovation has come to the fore as a key goal and directive for public sector organisations to become more efficient. This clarion call for innovation can be heard all around the world, with public services everywhere taking up the message to develop better, smarter, novel, more innovative processes, programs and policies. In the current push for innovation, networks are considered to be a superior vehicle through which collective knowledge can be shared and leveraged; replacing or at least supplementing the role function previously provided by inventive leaders...

Criminology and genetically modified food

Genetically modified or engineered foods are produced from rapidly expanding technologies that have sparked international debates and concerns about health and safety. These concerns focus on the potential dangers to human health, the risks of genetic pollution, and the demise of alternative farming techniques as well as biopiracy and economic exploitation by large private corporations. This article discusses the findings of the world's first Royal Commission on Genetic Modification conducted in New Zealand and reveals that there are potential social, ecological and economic risks created by genetically modified foods that require closer criminological scrutiny. As contemporary criminological discourses continue to push new boundaries in areas of crimes of the economy, environmental pollution, risk management, governance and globalization, the potential concerns posed by genetically modified foods creates fertile ground for criminological scholarship and activism.

Re-constructing Asianness in Australia : Yumi Umiumare, Owen Leong, and the remobilisation of monstrosity

In the late twentieth and early twenty-first centuries, Australia’s relationship with its Asian neighbours has been the subject of ongoing aesthetic, cultural and political contestations. As Alison Richards has noted, Australia’s colonial legacy, its Asia-Pacific location, and its ‘white’ self-perception have always made Australia’s relations with Asia fraught. In the latter part of the twentieth century, the paradoxes inherent in Australia’s relationships with and within the Asian region became a dominant theme in debates about nation, nationhood and identity, and prompted a shift in the construction of ‘Asianness’ on Australian stages. On the one hand, anxiety about the multicultural policy of the 1970s and 1980s, and then Prime Minister Paul Keating’s push for greater economic, cultural and artistic exchange with Asia via policies such as the Creative Nation Cultural Policy (1994), saw large numbers of Australians latch on to the reactionary, racist politics of Pauline Hanson’s One Nation Party. As Jacqueline Lo has argued, in this period Asian-Australians were frequently represented as an unassimilable Other, a threat to Australia’s ‘white’ identity, and to individual Australians’ jobs and opportunities. On the other hand, during the same period, a desire to counter the racism in Australian culture, and develop a ‘voice’ that would distinguish Australian cultural products from European theatrical traditions, combined with the new opportunities for cross-cultural exchange that came with the Creative Nation Cultural Policy to produce what Helen Gilbert and Jacqueline Lo have characterised as an Asian turn in Australian theatre...

New maps of learning for quality art education : what pre-service teachers should learn and be able to do

It would be a rare thing to visit an early years setting or classroom in Australia that does not display examples of young children’s artworks. This practice serves to give schools a particular ‘look’, but is no guarantee of quality art education. The Australian National Review of Visual Arts Education (NRVE) (2009) has called for changes to visual art education in schools. The planned new National Curriculum includes the arts (music, dance, drama, media and visual arts) as one of the five learning areas. Research shows that it is the classroom teacher that makes the difference, and teacher education has a large part to play in reforms to art education. This paper provides an account of one foundation unit of study (Unit 1) for first year university students enrolled in a 4-year Bachelor degree program who are preparing to teach in the early years (0–8 years). To prepare pre-service teachers to meet the needs of children in the 21st century, Unit 1 blends old and new ways of seeing art, child and pedagogy. Claims for the effectiveness of this model are supported with evidence-based research, conducted over the six years of iterations and ongoing development of Unit 1.

g4c2c: A model for citizen engagement at arms' length from government

The recognition that Web 2.0 applications and social media sites will strengthen and improve interaction between governments and citizens has resulted in a global push into new e-democracy or Government 2.0 spaces. These typically follow government-to-citizen (g2c) or citizen-to-citizen (c2c) models, but both these approaches are problematic: g2c is often concerned more with service delivery to citizens as clients, or exists to make a show of ‘listening to the public’ rather than to genuinely source citizen ideas for government policy, while c2c often takes place without direct government participation and therefore cannot ensure that the outcomes of citizen deliberations are accepted into the government policy-making process. Building on recent examples of Australian Government 2.0 initiatives, we suggest a new approach based on government support for citizen-to-citizen engagement, or g4c2c, as a workable compromise, and suggest that public service broadcasters should play a key role in facilitating this model of citizen engagement.

Handbook of service description

With the growth in number and sophistication of services widely available, there is a new urgency for comprehensive service descriptions that take into account both technical and business aspects. The last years have seen a number of efforts for best-of-breed service description focusing on specific aspects of services. The Handbook of Service Description provides the most advanced state of the art insights into these. The main parts of the book provide the most detailed documentation of the Unified Service Description Language (USDL) to date. USDL has been developed across several research institutes and publicly funded projects across Europe and Australia, currently extending to the Americas as part of a standardization push through W3C. The scope of services extends across IT and business, i.e., the socio-technical sense of services scaled to business networks. In this respect, purely human, purely automated and mixed human/automated services were considered, that have a boundary of cognizance that is available through the tasks of service provisioning, discovery, access and delivery. Taken together, the Handbook of Service Description provides a comprehensive reference suitable for a wide-reaching audience including researchers, practitioners, managers, and students who aspire to learn about or to create a deeper scientific foundation for service description and its methodological aspects.

Building Large Scale Traversability Maps Using Vehicle Experience

Traversability maps are a global spatial representation of the relative difficulty in driving through a local region. These maps support simple optimisation of robot paths and have been very popular in path planning techniques. Despite the popularity of these maps, the methods for generating global traversability maps have been limited to using a-priori information. This paper explores the construction of large scale traversability maps for a vehicle performing a repeated activity in a bounded working environment, such as a repeated delivery task.We evaluate the use of vehicle power consumption, longitudinal slip, lateral slip and vehicle orientation to classify the traversability and incorporate this into a map generated from sparse information.

Things that fall over : Women's playwriting, poetics and the (anti-)musical

Abstract: This study explores the contradictions and ambivalences experienced by a working artist at a time when her age, her gender, and broader cultural shifts are all potential obstacles or liabilities to creative flourishing. It is the product of practice-led research into the creative process from the perspective of the female "late bloomer". In this phrase, I have in mind the mature-aged woman who is, in mid-life, suddenly seized with inspiration and fired with creative energy. At its heart is the question: If an Elizabeth Jolley were in our midst today, would we hear from her? The result is a full-length libretto and accompanying exegetical binoculars in the form of a Preface and an Afterword. The creative work, Things That Fall Over (TTFO) is conceived in two parts: a libretto and oratorio for performance. It begins as a play, but over three acts and into a coda, the work becomes something entirely other - an (anti-) musical. The work grew from a personal interest in the nexus between women, ageing and creative practice, via investigation into the oeuvre of two Australian artists, Elizabeth Jolley, author, first published at age 53, and Rosalie Gascoigne, sculptor, first exhibited at 58. A second strand of the research grew from a fascination for the stage musical, especially in its more alternative modes as in the hands of Stephen Sondheim, or in more provocative manifestations as witnessed in recent Tony Award winners Avenue Q and The Book of Mormon. Contextually, this research is conducted at a time when anecdotal evidence suggests that women’s work in the performing arts and in literature is being pushed to the margins after a late twentieth century Golden Age on page and stage. Using hybrid practice-led methodologies - bricolage, log-keeping - and working within queer and feminist paradigms, this study seeks to counter that push with a new work that is all-female, part-pantomime, part monstrous allegory. In illuminating the creative process of a mature-aged playwright it concludes that hybrid and interstitial forms still offer an inclusive and democratic space in which voices that may otherwise be muted will continue to be heard.

Physical and linkage maps for Drosophila serrata, a model species for studies of clinal adaptation and sexual selection

Drosophila serrata is a member of the montium group, which contains more than 98 species and until recently was considered a subgroup within the melanogaster group. This Drosophila species is an emerging model system for evolutionary quantitative genetics and has been used in studies of species borders, clinal variation and sexual selection. Despite the importance of D. serrata as a model for evolutionary research, our poor understanding of its genome remains a significant limitation. Here, we provide a first-generation gene-based linkage map and a physical map for this species. Consistent with previous studies of other drosophilids we observed strong conservation of genes within chromosome arms homologous with D. melanogaster but major differences in within-arm synteny. These resources will be a useful complement to ongoing genome sequencing efforts and QTL mapping studies in this species

Celebrating a Common and Uncommon Ground - A Case Study

Interaction design is about finding better ways for people to interact with each other through communication technologies. Interaction design involves understanding how people learn, work and play so that we can engineer better, more valuable technologies that are more appropriate to the contexts of their lives. As an academic discipline, interaction design is about the people-research that underpins these technologies. As a comparative tool for business it is about creating innovations that have market pull rather than a technology push. Many examples can be found which demonstrate the value of interaction design within both industry and academia, however finding the common ground between this spectrum of activity is often difficult. Differences in language, approach and outcomes often lead to researchers from either side of the spectrum complaining of an uncommon ground, which often results in a lack of collaboration within such projects. However, as demonstrated through this case study, rather than focussing on finding a common ground to assist in better collaboration between industry and academia, celebrating the uniqueness of each approach whilst bridging them with a common language can lead to new knowledge and commercial innovation. This case study will focus on the research and development phase of a Diversionary Therapy Platform, a collaboration between the Australasian CRC for Interaction Design and The Royal Children's Hospital (Brisbane, Australia). This collaborative effort has led to the formation of a new commercial venture, Diversionary Therapy Pty Ltd, which aims to bring to the market the research outcomes from the project. The case study will outline the collaborative research and development process undertaken between the many stakeholders and reflect on the challenges identified within this process. A key finding from this collaboration was allowing for the co-existence of the common and uncommon ground throughout the project. This concept will be discussed further throughout this paper.

Asian-Australian Children’s Literature and Publishing (AACLAP)

Led by Queensland University of Technology, the Asian-Australian Children’s Literature and Publishing (AACLAP)research project investigates and records details of Australian children’s literature that is set in Asia and/or that represents Asian-Australian cultures and experiences and literature that is published in selected Asian languages. This includes East Asia, Southeast Asia, South Asia, and the Bay of Bengal. The AACLAP dataset is a comprehensive collection of agent and work records related to ’Asia’, including, but not limited to, autobiography, fiction, criticism, poetry, drama, short stories, and picture books, published during a forty-year period from 1970 to 2010. The dataset provide valuable primary and secondary sources that are important for developing literature-focused educational programs in line with the national government’s push for Asia Literacy. AACLAP is a subset of AustLit, the virtual research environment and information resource for Australian literary, print, and narrative culture scholars, students, and the public.
