In this paper we construct earthwork allocation plans for a linear infrastructure road project. Fuel consumption metrics and an innovative block partitioning and modelling approach are applied to reduce costs. 2D and 3D variants of the problem were compared to see what effect, if any, occurs on solution quality. 3D variants were also considered to see what additional complexities and difficulties occur. The numerical investigation shows a significant improvement and a reduction in fuel consumption as theorised. The proposed solutions differ considerably from plans that were constructed for a distance based metric as commonly used in other approaches. Under certain conditions, 3D problem instances can be solved optimally as 2D problems.

The purpose of this study was to determine factors (internal and external) that influenced Canadian provincial (state) politicians when making funding decisions about public libraries. Using the case study methodology, Canadian provincial/state level funding for public libraries in the 2009-10 fiscal year was examined. After reviewing funding levels across the country, three jurisdictions were chosen for the case: British Columbia's budget revealed dramatically decreased funding, Alberta's budget showed dramatically increased funding, and Ontario's budget was unchanged from the previous year. The primary source of data for the case was a series of semi-structured interviews with elected officials and senior bureaucrats from the three jurisdictions. An examination of primary and secondary documents was also undertaken to help set the political and economic context as well as to provide triangulation for the case interviews. The data were analysed to determine whether Cialdini's theory of influence (2001) and specifically any of the six tactics of influence (i.e, commitment and consistency, authority, liking, social proof, scarcity and reciprocity) were instrumental in these budget processes. Findings show the principles of "authority", "consistency and commitment" and "liking" were relevant, and that "liking" were especially important to these decisions. When these decision makers were considering funding for public libraries, they most often used three distinct lenses: the consistency lens (what are my values? what would my party do?), the authority lens (is someone with hierarchical power telling me to do this? are the requests legitimate?), and most importantly, the liking lens (how much do I like and know about the requester?). These findings are consistent with Cialdini's theory, which suggests the quality of some relationships is one of six factors that can most influence a decision maker. The small number of prior research studies exploring the reasons for increases or decreases in public library funding allocation decisions have given little insight into the factors that motivate those politicians involved in the process and the variables that contribute to these decisions. No prior studies have examined the construct of influence in decision making about funding for Canadian public libraries at any level of government. Additionally, no prior studies have examined the construct of influence in decision making within the context of Canadian provincial politics. While many public libraries are facing difficult decisions in the face of uncertain funding futures, the ability of the sector to obtain favourable responses to requests for increases may require a less simplistic approach than previously thought. The ability to create meaningful connections with individuals in many communities and across all levels of government should be emphasised as a key factor in influencing funding decisions.

We consider how data from scientific research should be used for decision making in health services. Whether a hand hygiene intervention to reduce risk of nosocomial infection should be widely adopted is the case study. Improving hand hygiene has been described as the most important measure to prevent nosocomial infection. 1 Transmission of microorganisms is reduced, and fewer infections arise, which leads to a reduction in mortality2 and cost savings.3 Implementing a hand hygiene program is itself costly, so the extra investment should be tested for cost-effectiveness.4,5 The first part of our commentary is about cost-effectiveness models and how they inform decision making for health services. The second part is about how data on the effectiveness of hand hygiene programs arising from scientific studies are used, and 2 points are made: the threshold for statistical inference of .05 used to judge effectiveness studies is not important for decision making,6,7 and potentially valuable evidence about effectiveness might be excluded by decision makers because it is deemed low quality.8 The ideas put forward will help researchers and health services decision makers to appraise scientific evidence in a more powerful way.

An evolution in the use of digital modelling has occurred in the Queensland Department of Public Works Division of Project Services over the last 20 years from: the initial implementation of computer aided design and documentation (CADD); to experimentation with building information modelling (BIM); to embedding integrated practice (IP); to current steps towards integrated project delivery (IPD) including the active involvement of consultants and contractors in the design/delivery process. This case study is one of three undertaken through the Australian Sustainable Built Environment National Research Centre investigating past R&D investment. The intent of these cases is to inform the development of policy guidelines for future investment in the construction industry in Australia. This research is informing the activities of CIB Task Group 85 R&D Investment and Impact. The uptake of digital modelling by Project Services has been approached through an incremental learning approach. This has been driven by a strong and clear vision with a focus on developing more efficient delivery mechanisms through the use of new technology coupled with process change. Findings reveal an organisational focus on several areas including: (i) strategic decision making including the empowerment of innovation leaders and champions; (ii) the acquisition and exploitation of knowledge; (iii) product and process development (with a focus on efficiency and productivity); (iv) organisational learning; (v) maximising the use of technology; and (vi) supply chain integration. Key elements of this approach include pilot projects, researcher engagement, industry partnerships and leadership.

The term ‘partnership’ is increasingly used by governments, industry, community organisations and schools in supporting their daily businesses. Similar to the terms ‘ICT’ and ‘learning’, ‘partnerships’ are now ubiquitous in policy discourse. Yet, the term remains ill-defined and ambiguous. This study reviews and reflects on a government led industry-school partnership initiative in the state of Queensland, Australia, to understand how the term is used in this initiative. Given the frequent use of Public Private Partnership (PPP) language, PPP was used as a framework to review this initiative. The methodology of this qualitative case study involved consultations with stakeholders and an analysis of Gateway schools documents, policy documents, and literature. The review suggests that despite the use of terminology akin to PPP projects in Gateway school and policy documents, the implicit suggestion that this initiative is a public-private partnership is untenable. The majority of principles shaping a PPP have not been considered to a significant extent in the Gateway project. Although the review recognises the legitimate and sincere purpose of the Gateway schools initiative, the adoption of a PPP framework during the design, monitoring, or evaluation stages could have strengthened the initiative in terms of outcomes, benefits, and sustainability.

This study investigated the relationships between knowledge and efficacy for teaching sustainability in a sample of 266 pre-service primary teachers at a large, metropolitan university in Australia. A survey gathered information about the participant’s attitudes and self-efficacy for education for sustainability, along with their perceived and actual knowledge of environmental sustainability issues. The participants typically believed they were confident in their abilities to engage with education for sustainability with self-efficacy increasing with increased levels of perceived knowledge. However no relationship was found between perceived knowledge and actual knowledge which suggests that the participants either do not feel constrained by their lack of knowledge, or are perhaps unaware of their actual knowledge of sustainability issues. This lack of relationship may have implications for the development of pedagogical content knowledge with pre-service teachers potentially developing shallow, tokenistic approaches to Education for Sustainability.

This paper presents a case study chronicling the development of WebAIRS, an Australasian national anaesthetic incident reporting database for health care practitioners. WebAIRS is an example of the multidisciplinary nature of the IS discipline, incorporating IS theories, tools and principles in the creation of an IT artefact with significant real world application. This case study introduces the background of the project and the motivations for its conception including the need for critical incident reporting in anaesthesia, the process of its development using IT students and the problems identified following its national release among the anaesthetic community. The paper demonstrates the evolution of contemporary IS research and the IT artefact, and how each can be crucial foundations for hospitals of the future

This research develops a new framework to be used as a tool for analysing and designing walkable communities. The literature review recognises the work of other researchers combining their findings with the theory of activity nodes and considers how a framework may be used on a more global basis. The methodology develops a set of criteria through the analysis of noted successful case studies and this is then tested against an area with very low walking rates in Brisbane, Australia. Results of the study suggest that as well as the accepted criteria of connectivity, accessibility, safety, security, and path quality further criteria in the form or planning hierarchy, activity nodes and climate mitigation could be added to allow the framework to cover a broader context. Of particular note is the development of the nodal approach, which allows simple and effective analysis of existing conditions, and may also prove effective as a tool for planning and design of walkable communities.

Current literature warns organisations about a global ageing phenomenon. Workplace ageing is causing a diminishing work pool which has consequences for a sustainable workforce in the future. This phenomenon continues to impact on local government councils in Australia. Australia has one of the world’s most rapidly ageing populations, and there is evidence that Australian local government councils are already resulting in an unsustainable workforce. Consequently, this research program investigated the role of older workers in the Queensland local government workplace in enabling them to extend their working lives towards transitional employment and a sustainable workforce in the future. Transitional Employment is intended as a strategy for enabling individuals to have greater control over their employment options and their employability during the period leading to their final exit from the workforce. There was no evidence of corporate support for older workers in Queensland local government councils other than tokenistic government campaigns encouraging organisations to "better value their older workers". (Queensland Government, 2007d, p.6). TE is investigated as a possible intervention for older workers in the future. The international and national literature review reflected a range of matters impacting on current older workers in the workforce and barriers preventing them from accessing services towards extending their employment beyond the traditional retirement age (60 years) as defined by the Australian Government; an age when individuals can access their superannuation. Learning and development services were identified as one of those barriers. There was little evidence of investment in or consistent approaches to supporting older workers by organisations. Learning and development services appeared at best to be ad hoc, reactive to corporate productivity and outputs with little recognition of the ageing phenomenon (OECD, 2006, p.23) and looming skills and labour shortages (ALGA, 2006, p. 19). Themes from the literature review led to the establishment of three key research questions: 1. What are the current local government workforce issues impacting on skills and labour retention? 2. What are perceptions about the current workplace environment? And, 3. What are the expectations about learning and development towards extending employability of older workers within the local government sector? The research questions were explored by utilising three qualitative empirical studies, using some numerical data for reporting and comparative analysis. Empirical Study One investigated common themes for accessing transitional employment and comprised two phases. A literature review and Study One data analysis enabled the construction of an initial Transitional Employment Model which includes most frequent themes. Empirical Study Two comprised focus groups to further consider those themes. This led to identification of issues impacting the most on access to learning and development by older workers and towards a revised TEM. Findings presented majority support for transitional employment as a strategy for supporting older workers to work beyond their traditional retirement age. Those findings are presented as significant issues impacting on access to transitional employment within the final 3-dimensionsal TEM. The model is intended as a guide for responding to an ageing workforce by local government councils in the future. This study argued for increased and improved corporate support, particularly for learning and development services for older workers. Such support will enable older workers to maintain their employability and extend their working lives; a sustainable workforce in the future.

The legitimate resolution of disputes in online environments requires a complex understanding of the social norms of the community. The conventional legal approach to resolving disputes through literal interpretation of the contractual terms of service is highly problematic because it does not take into account potential conflict with community expectations. In this paper we examine the importance of consent to community governance and argue that a purely formal evaluation of consent is insufficient to legitimately resolve disputes. As online communities continue to grow in importance to the lives of their participants, the importance of resolving disputes legitimately, with reference to the consent of the community, will also continue to grow. Real consent, however, is difficult to identify. We present a case study of botting and real money trading in EVE Online that highlights the dynamic interaction of community norms and private governance processes. Through this case study, we argue that the major challenge facing regulators of online environments is that community norms are complex, contested, and continuously evolving. Developing legitimate regulatory frameworks then depends on the ability of regulators to create efficient and acceptable modes of dispute resolution that can take into account (and acceptably resolve) the tension between formal contractual rules and complex and conflicting community understandings of acceptable behaviour.

Practice-led journalism research techniques were used in this study to produce a ‘first draft of history’ recording the human experience of survivors and rescuers during the January 2011 flash flood disaster in Toowoomba and the Lockyer Valley in Queensland, Australia. The study aimed to discover what can be learnt from engaging in journalistic reporting of natural disasters. This exegesis demonstrates that journalism can be both a creative practice and a research methodology. About 120 survivors, rescuers and family members of victims participated in extended interviews about what happened to them and how they survived. Their stories are the basis for two creative outputs of the study: a radio documentary and a non-fiction book, that document how and why people died, or survived, or were rescued. Listeners and readers are taken "into the flood" where they feel anxious for those in peril, relief when people are saved, and devastated when babies, children and adults are swept away to their deaths. In undertaking reporting about the human experience of the floods, several significant elements about journalistic reportage of disasters were exposed. The first related to the vital role that the online social media played during the disaster for individuals, citizen reporters, journalists and emergency services organisations. Online social media offer reporters powerful new reporting tools for both gathering and disseminating news. The second related to the performance of journalists in covering events involving traumatic experiences. Journalists are often required to cover trauma and are often amongst the first-responders to disasters. This study found that almost all of the disaster survivors who were approached were willing to talk in detail about their traumatic experiences. A finding of this project is that journalists who interview trauma survivors can develop techniques for improving their ability to interview people who have experienced traumatic events. These include being flexible with interview timing and selecting a location; empowering interviewees to understand they don’t have to answer every question they are asked; providing emotional security for interviewees; and by being committed to accuracy. Survivors may exhibit posttraumatic stress symptoms but some exhibit and report posttraumatic growth. The willingness of a high proportion of the flood survivors to participate in the flood research made it possible to document a relatively unstudied question within the literature about journalism and trauma – when and why disaster survivors will want to speak to reporters. The study sheds light on the reasons why a group of traumatised people chose to speak about their experiences. Their reasons fell into six categories: lessons need to be learned from the disaster; a desire for the public to know what had happened; a sense of duty to make sure warning systems and disaster responses to be improved in future; personal recovery; the financial disinterest of reporters in listening to survivors; and the timing of the request for an interview. Feedback to the creative-practice component of this thesis - the book and radio documentary - shows that these issues are not purely matters of ethics. By following appropriate protocols, it is possible to produce stories that engender strong audience responses such as that the program was "amazing and deeply emotional" and "community storytelling at its most important". Participants reported that the experience of the interview process was "healing" and that the creative outcome resulted in "a very precious record of an afternoon of tragedy and triumph and the bitter-sweetness of survival".

Targeting females at high school or earlier may be a key towards engaging them in science, technology, engineering and mathematics (STEM) education. This ethnographic study, part of a three-year longitudinal research project, investigated Year 8 female students’ learning about engineering concepts associated with designing, constructing, testing, and evaluating a catapult. There was a series of lead-up lessons and four lessons for the catapult challenge (total of 18 x 45-minute lessons) over a nine-week period. Data from two girls within a focus group showed that they needed to: (1) receive clarification on engineering terms to facilitate more fluent discourse, (2) question and debate conceptual understandings without peers being judgemental, and (3) have multiple opportunities for engaging with materials towards designing, constructing and explaining key concepts learnt. There are implications for teachers facilitating STEM education, such as: clarifying STEM terms, articulating how students can interact in non-judgmental ways, and providing multiple opportunities for interacting within engineering education.

This case study investigated pedagogical responses to internationalisation by a faith-based secondary school in Australia. Using social constructivism as the theoretical framework the study examined teaching and learning for culturally and linguistically diverse students. Data generated through questionnaires, focus groups, individual interviews and document archives were analysed and interpreted using thematic analysis. The findings showed that teachers believed themselves to be ill-equipped to teach international students. Their concerns centred on a lack of explicit pedagogical, cultural and linguistic knowledge to help the students acculturate and learn. Recommendations include the dissemination of school policies to teachers, intentional staff collaboration and professional development to address the teachers’ needs for internationalisation.

The suggested model of an ideal public sector corruption commission includes oversight by a parliamentary committee with an attached parliamentary inspector (Prenzler, 2009). However, little research has been conducted on parliamentary oversight of corruption commissions. In Queensland, a role of the Parliamentary Crime and Misconduct Committee, which has the Parliamentary Crime and Misconduct Commissioner attached, is to review the Crime and Misconduct Commission every three years. This paper considers the public written and oral submissions made to the Parliamentary Crime and Misconduct Committee in the four reviews of the Crime and Misconduct Committee conducted to date (2004, 2006, 2009 and 2012). By doing this, the paper will begin to identify the gaps in our understanding of the relationship between parliamentary committees and public sector corruption commissions and the processes used by parliamentary committees to provide oversight of corruption commissions.

This research study sought to understand why so many early career teachers in an Australian Religious Institute education sector were leaving teaching. Previous studies on early career teacher attrition across all sectors were based on supply and demand theory, as well as contemporary career theory, and identified various factors such as remuneration, student behaviour and school resourcing as influencing factors. These Australian Religious Institute education sector schools take pride in their good standing. The schools in this sector have worked at addressing many of the factors associated with early career teacher attrition yet despite their efforts they are also experiencing attrition of their early career teachers. A case study of the Queensland independent Catholic girls' school sector explored firstly, the construct of being a teacher in these schools, and secondly, the sociocultural discourses giving rise to unique situations contributing to early career teachers making the decision to leave teaching. Eight early career teachers who had left the profession for which they had recently trained, and eight long standing teachers who were still employed in the sector were interviewed to yield a rich data set. The interviews were conducted within a theoretical framework of what it means to be a teacher by Graham and Phelps (2003) and pedagogic identity and pedagogic practice as noted by Bernstein (2000). The distributive rules and the evaluative rules (Bernstein, 2000) provided the analytical framework to confirm that particular discourses, together with the ways in which the early career teachers realised being a teacher, were important factors in the decision not to remain in teaching. It emerged that being a teacher in the Queensland independent Catholic girls' school sector was complex and demanding. Being a teacher required long hours of personal time to realise the demands of teaching, a situation which did not fare well with the early career teachers who struggled to balance the requirements of teaching with their own personal time. Furthermore, evidence was found that the schools had multifaceted sociocultural discourses that the early career teacher research participants struggled to understand. In contrast, long standing teachers had, through time, experience and observation, developed skills that allowed them to navigate these complex discourses and thus remain long term in the sector. Another finding revealed the considerable dichotomy in how the charism of the schools (the unique way Catholic institutions transmit the beliefs and teachings of the Catholic Church) unfolded for students and staff. While these schools transmit their charism effectively to the students, it is ineffectively transmitted to early career teachers. In contemporary times when a majority of teachers in Australia are moving into their 50s and large numbers are retiring or resigning, (Australian Government, 2011; Australian Government Department of Education, 2007b) it is important for the long term viability of the independent Catholic school sector to retain a stable staff. This study demonstrates that if Catholic schools want to retain their unique identity in the education community and sustain their unique charisms, then they must adopt positive practices to support early career teachers.
