Full scale experiments of a steel portal frame building

While numerous full scale experimental programs have been conducted around the world over the past 50 years to investigate the behaviour of steel portal frame buildings, none have comprehensively investigated the behaviour of such buildings under wind uplift. Wind uplift loads often govern designs in the Australian environment and this became the subject of a recent research project at Queensland University of Technology (OUT). This paper describes the full scale experiments on a steel portal frame building subject to wind uplift, racking and gravity loads. The portal rafter and column members utilised hollow flange beam (HFB) sections [5-8] though the paper's findings on the theoretical and experimental building responses relate to conventional types of steel portal frame buildings.

Innovation in Road Building: Removing Obstacles for Diffusion of Novel Building Products

How can obstacles to innovation be overcome in road construction? Using a focus group methodology, and based on two prior rounds of empirical work, the analysis in this chapter generates a set of four key solutions to two main construction innovation obstacles: (1) restrictive tender assessment and (2) disagreement over who carries the risk of new product failure. The four key solutions uncovered were: 1) pre-project product certification; 2) past innovation performance assessment; 3) earlier involvement of product suppliers and road asset operators; and 4) performance-based specifications. Additional research is suggested in order to illicit deeper insights into possible solutions to construction innovation obstacles, and should emphasise furthering the theoretical interpretation of empirical phenomena.

Towards sustainable poverty alleviation: Building NGO accountability to beneficiaries in microenterprise development programs

This thesis investigates the operations of non-government organisations (NGOs) engaging in microenterprise development programs in Bangladesh and Indonesia, to understand the nature and mechanisms of NGO accountability to the poor. Findings reveal both barriers and mechanisms contributing to success within these programs. A range of mechanisms enhance both accountability of NGOs and the poor, facilitating more effective programs and sustainable poverty alleviation.

Team building activities in dance and discoveries from reflective essays

The purpose of this study was to determine if using team building activities within a university Latin dance course enhances cohesion. Students (N=30) completed the Group Environment Questionnaire (GEQ; Carron, Widmeyer, & Brawley, 1985), which measures group integration (individuals’ perceptions of the closeness, similarity, and bonding within the group as a whole) and individual attractions to the group in terms of both task and social cohesion. Students also completed an evaluation of the team building activities and wrote reflective essays about their experiences in the course. The course consisted of twenty 90-minute classes. In the third class students were provided an information sheet describing the research. In the fourth class the students completed a demographics questionnaire and the GEQ. The students completed the GEQ again during the ninth class. In classes 10 to 14 team building activities took up roughly the first third of each class. The students completed the GEQ again in classes 15 and 20. In class 16 the students completed the evaluation. The reflective essays were submitted two weeks after the last class. There were no significant differences across time in social cohesion. Group integration task, however, was significantly higher at times 3 and 4 compared to time 1. Students agreed that the team-building activities helped to bond class members, and felt it was valuable for these activities to be included in the unit in the future. The reflective essays indicated the students felt the team building activities improved social factors, and interpersonal, dance, and personal mental skills.

A review of benchmarking in carbon labelling schemes for building materials

As one of the largest sources of greenhouse gas (GHG) emissions, the building and construction sector is facing increasing pressure to reduce its life cycle GHG emissions. One central issue in striving towards reduced carbon emissions in the building and construction sector is to develop a practical and meaningful yardstick to assess and communicate GHG results through carbon labelling. The idea of carbon labelling schemes for building materials is to trigger a transition to a low carbon future by switching consumer-purchasing habits to low-carbon alternatives. As such, failing to change purchasing pattern and behaviour can be disastrous to carbon labelling schemes. One useful tool to assist customers to change their purchasing behaviour is benchmarking, which has been very commonly used in ecolabelling schemes. This paper analyses the definition and scope of benchmarking in the carbon labelling schemes for building materials. The benchmarking process has been examined within the context of carbon labelling. Four practical issues for the successful implementation of benchmarking, including the availability of benchmarks and databases, the usefulness of different types of benchmarks and the selection of labelling practices have also been clarified.

An Electron-Accepting Chromophore Based on Fluorene and Naphthalenediimide Building Blocks for Solution-Processable Bulk Heterojunction Devices

We have designed, synthesized and utilized a new non-fullerene electron acceptor, 9,9′-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(2,7-dioctyl-4-(octylamino)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone) (B2), for use in solution-processable bulk-heterojunction devices. B2 is based on a central fluorene moiety, which was capped at both ends with an electron-accepting naphthalenediimide functionality. B2 exhibited excellent solubility (>30 mg mL−1 in chloroform), high thermal and photochemical stability, and appropriate energy levels for use with the classical polymer donor regioregular poly(3-hexylthiophene). A power conversion efficiency of 1.16 % was achieved for primitive bulk-heterojunction devices with a high fill factor of approximately 54 %.

Community development and community resilience: An integrative approach

Throughout history, communities and civilizations have sought to enhance the quality of community life and the well-being of its people. However, more recently there has been greater interest in attending to the details of community development by capitalizing on the improved ability to capture community well-being and successes scientifically. That interest invites greater attention to the development of indicators that can quantify those qualities of life that lead to strong and healthy communities. The selection of meaningful indicators is dependent upon several factors including a process that stimulates meaningful involvement of community stakeholders, but the single most important is the identification of an underlying model to guide the work. Indicators do not have meaning in themselves. For these measures to provide a coherent assessment of the community, an integrative approach to understanding what constitutes a healthy and strong community in a dynamic environment is required. A resilience perspective serves that purpose and provides a framework that is broad, neutral, and conceptually strong enough to structure development of significant sets of indicators. Exemplary community indicator processes across the nation, particularly recent efforts in the Phoenix, Arizona region, provide evidence supporting the value of indicator development for community building.

This poster presents findings from a social media work package, and preliminary findings from the focus group work package on emergency warning message comprehension.

Theorising youth and everyday peace(building)

This essay presents a locally-grounded theoretical framework for studying youth and everyday peace(building). Drawing on examples from fieldwork as well as insights from the articles to follow in the journal, the essay highlights three interrelated and overlapping spheres of inquiry. First, it makes the case for examining the age-specific as well as gender-, and other contextually-specific roles of youth as they relate to everyday peacebuilding. Second, the essay draws attention to how everyday peace is narrated by or through youth. It poses questions about what values, policies, and governmental structures are specifically being resisted and rejected, and how peace is conceptualised and/or hidden in the narratives of youth. Third, along with these concerns, the nexus of global and local (including discursive and institutional) structures that facilitate, curtail, and curtain everyday peace (building) practices are important to identify and evaluate for their impacts on the roles and ideas of youth. In proposing this theoretical framework that recognises the complex and multiple ways youth are engaged in their everyday worlds, this essay asks how we can engage this recognition within knowledges and practices of everyday peace(building).

Research around practice partnerships: An example of building partnerships to address overweight and obesity in children

Prevention and management of childhood overweight and obesity is a health priority for governments and communities throughout the developed world. A conceptual model, Research around Practice in Childhood Obesity (RAPICO), has been developed to guide capacity building in a coordinated 'bench to fieldwork' initiative to address this public health problem. Translation of research findings into sustainable responses with optimal fit requires consideration of context-specific relevance, cost-effectiveness, feasibility and levels of available support. The RAPICO model uses program theory to describe a framework for progressing practitionercommunityresearch partnerships to address low, medium and high levels of risk for childhood overweight and obesity within community settings. A case study describing the development of a logic model to inform risk-linked responses to childhood overweight and obesity is presented for the Ipswich community in south-east Queensland.

The application of building information modeling to enhance organisational learning

The construction industry is a knowledge-based industry where various actors with diverse expertise create unique information within different phases of a project. The industry has been criticized by researchers and practitioners as being unable to apply newly created knowledge effectively to innovate. The fragmented nature of the construction industry reduces the opportunity of project participants to learn from each other and absorb knowledge. Building Information Modelling (BIM), referring to digital representations of constructed facilities, is a promising technological advance that has been proposed to assist in the sharing of knowledge and creation of linkages between firms. Previous studies have mainly focused on the technical attributes of BIM and there is little evidence on its capability to enhance learning in construction firms. This conceptual paper identifies six ‘functional attributes’ of BIM that act as triggers to stimulate learning: (1) comprehensibility; (2) predictability; (3) accuracy; (4) transparency; (5) mutual understanding and; (6) integration.

Exploring accuracy factors in cost estimating practice towards implementing Building Information Modelling (BIM)

Cost estimating has been acknowledged as a crucial component of construction projects. Depending on available information and project requirements, cost estimates evolve in tandem with project lifecycle stages; conceptualisation, design development, execution and facility management. The premium placed on the accuracy of cost estimates is crucial to producing project tenders and eventually in budget management. Notwithstanding the initial slow pace of its adoption, Building Information Modelling (BIM) has successfully addressed a number of challenges previously characteristic of traditional approaches in the AEC, including poor communication, the prevalence of islands of information and frequent reworks. Therefore, it is conceivable that BIM can be leveraged to address specific shortcomings of cost estimation. The impetus for leveraging BIM models for accurate cost estimation is to align budgeted and actual cost. This paper hypothesises that the accuracy of BIM-based estimation, as more efficient, process-mirrors of traditional cost estimation methods, can be enhanced by simulating traditional cost estimation factors variables. Through literature reviews and preliminary expert interviews, this paper explores the factors that could potentially lead to more accurate cost estimates for construction projects. The findings show numerous factors that affect the cost estimates ranging from project information and its characteristic, project team, clients, contractual matters, and other external influences. This paper will make a particular contribution to the early phase of BIM-based project estimation.

Cost estimating practice incorporating Building Information Modelling (BIM): Malaysian Quantity Surveyors perspectives

Cost estimating is a key task within Quantity Surveyors’ (QS) offices. Provision of an accurate estimate is vital to ensure that the objectives of the client are met by staying within the client’s budget. Building Information Modelling (BIM) is an evolving technology that has gained attention in the construction industries all over the world. Benefits from the use of BIM include cost and time savings if the processes used by the procurement team are adapted to maximise the benefits of BIM. BIM can be used by QSs to automate aspects of quantity take-off and the preparation of estimates, decreasing turnaround time and assist in controlling errors and inaccuracies. The Malaysian government has decided to require the use of BIM for its projects beginning from 2016. However, slow uptake is reported in the use of BIM both within companies and to support collaboration within the Malaysian industry. It has been recommended that QSs to start evaluating the impact of BIM on their practices. This paper reviews the perspectives of QSs in Malaysia towards the use of BIM to achieve more dependable results in their cost estimating practice. The objectives of this paper include identifying strategies in improving practice and potential adoption drivers that lead QSs to BIM usage in their construction projects. From the expert interviews, it was found out that, despite still using traditional methods and not practising BIM, the interviewees still acquire limited knowledge related to BIM. There are some drivers that potentially motivate them to employ BIM in their practices. These include client demands, innovation in traditional methods, speed in estimating costs, reduced time and costs, improvement in practices and self-awareness, efficiency in projects, and competition from other companies. The findings of this paper identify the potential drivers in encouraging Malaysian Quantity Surveyors to exploit BIM in their construction projects.

Speaking of supervision: A dialogic approach to building higher degree research supervision capacity in the creative arts

In the emergent field of creative practice higher degrees by research, first generation supervisors have developed new models of supervision for an unprecedented form of research that combines creative practice and written thesis. In a national research project, entitled 'Effective supervision of creative practice higher research degrees', we set out to capture and share early supervisors' insights, strategies and approaches to supporting their creative practice PhD students. From the insights we gained during the early interview process, we expanded our research methods in line with a distributed leadership model and developed a dialogic framework. This led us to unanticipated conclusions and unexpected recommendations. In this study, we primarily draw on philosopher and literary theorist Mikhail Bakhtin's dialogics to explain how giving precedence to the voices of supervisors not only facilitated the articulation of dispersed tacit knowledge, but also led to other 20 discoveries. These include the nature of supervisors' resistance to prescribed models, policies and central academic development programmes; the importance of polyvocality and responsive dialogue in enabling continued innovation in the field; the benefits to supervisors of reflecting, discussing and sharing practices with colleagues; and the value of distributed leadership and dialogue to academic development and supervision capacity building in research education.
