Preparing construction project managers to document professional growth

Deakin University&rsquo;s School of Architecture and Building is renowned for producing graduates who possess relevant attributes that make them job ready for the building and construction industry. Graduate destination surveys indicate that in the last eight (8) years, 100% of all Infrastructure Logistics (Construction and Facility Management) course graduates found relevant employment. This success is a direct result of a curriculum that is responsive to industry needs alongside educational methodology that focuses on excellent teaching and research while seeking new ways of developing and delivering courses. The Infrastructure Logistics course prepares graduates to successfully compete in today&rsquo;s global job market, and allows them to showcase relevant knowledge and skills that are critical in seeking and sustaining employment. Traditionally, tailored resumes served this purpose; however, in many professional fields, professional portfolios are now becoming a more desirable way of providing a summary of relevant attributes alongside evidence of professional abilities. Sustaining employment, appraisals, and applying for a promotion are often subject to adequate evidence of professional standards and growth. Professional bodies require records of contribution to Continuing Professional Development (CPD) schemes; and accrediting organisations require professionals applying for professional registration to provide documented evidence of their relevant experience and abilities. The Australian Institute of Project Management (AIPM 2007) requires candidates wanting to become Registered Project Managers (RegPM) to demonstrate their current work-based experience and competencies.This paper reports on a teaching strategy adopted in the Project Management (PM) stream, offered as part of Infrastructure Logistic courses. The teaching strategy is based on a combination of constructivism theory of learning, problem and project based learning, and active learning. The strategy requires systematic reflection and conscious creation of documented evidence of PM attributes and competences in the form of a portfolio.Preliminary results of action research monitoring the effectiveness of systematic reflection indicate that students respond very positively to the idea of professional journals and professional portfolios. Preliminary results also indicate that students accept reflection and conscious documentation of their achievements as an integral part of their study and future practice.<br /

The role of assessment in the development of judgement

This paper introduces an integrated assessment model developed within a project management discipline stream in a Construction Management course. Following Boud and Falchikov (2007) this model starts with practice, that is, the actual &lsquo;doing&rsquo; of project management as the basis for shaping assessment that equips students to learn for the rest of their lives. Practice is understood as a holistic conception of what professionals do in particular contexts, and a theoretical construct that provides a method of framing ways in which we can investigate the world (Schatzki, 2001). This approach opens the way for considerations of assessment that engage with, and cultivate, certain kinds of professional learning and identity formation including the development of judgement. Integral to the model is the non-sequential nature of assessment activities, evolving team formation and ongoing self and communal reflection. The paper concludes that the use of an authentic and integrated assessment model creates a compelling learning environment that contributes meaningfully to the development of skills, knowledge and identities for future professional learning.<br /

Environmentally friendly sound absorbing noise barrier made from concrete waste - further developments

This paper reports on the second phase of a research project aimed at the development of an environmentally friendly noise barrier for urban freeways, also known as KMAK [1]. The concrete barrier, which has some unique capabilities to mitigate transportation noise, is made from recycled concrete (RC) aggregate and industrial by-products such as fly ash and reclaimed water. The current developmental work expands on a research project that resulted in a two-layer (2L) concrete barrier. Two prototypes of the 2L barrier were produced, followed by extensive acoustic testing and a number of simulations where standard timber and/or concrete barriers were substituted with KMAK barrier [2]. Current research investigates a variety of architectural finishes applied to the original KMAK barrier with the aim of improving its visual appearance and also fine-tuning its acoustic performance. The new three-layer (3L) barrier optimizes sound absorption in a frequency range characteristic similar to that of transportation noise, especially road traffic noise. Three major aspects related to the development of architectural finishes were considered; environmentally responsible materials, surface features, and production methods. The findings of the current investigation demonstrate that there is a positive correlation between surface features, percentage of perforation as well as depth of the architectural layer, and increased potential of the 3L barrier to mitigate transportation noise. On average, the addition of perforated architectural finish contributes to a 20% increase in sound absorption. The preliminary results also show that the sound absorbency of the 3L barrier can be better controlled and tuned to specific noise frequency than the 2L type. The visual appearance has been significantly improved with the addition of the architectural finish, which makes the barrier an attractive, feasible, and viable alternative to road barriers made from standard concrete or timber.<br /

Social influence and student choice of higher education institution

This conceptual paper discusses changes in higher education sector, growing competition as a result of new private education providers and the adoption of student-as-customer perspective in recruitment and marketing of higher education institutions. The paper reviews numerous models of student choice and identifies inconsistencies in the role of social factors in the student choice. These inconsistencies are of special importance in current higher education landscape and growing prominence of peer-to-peer communication via social media. Consequently, a thorough understanding of influences that effect student choice of higher education institution is imperative. This conceptual paper puts forward a conceptual framework that integrates Kelman’s processes of social influence and Cialdini-Goldstein’s goals that underpin the acceptance of that influence to examine the effects social context has on student choice of higher education institution

2Loud? Monitoring traffic noise with mobile phones

The World Health Organization has recently focused attention on guidelines for night noise in urban areas, based on significant medical evidence of the adverse impacts of exposure to excessive traffic noise on health, especially caused by sleep disturbance. This includes serious illnesses, such as hypertension, arteriosclerosis and myocardial infarction. 2Loud? is a research project with the aim of developing and testing a mobile phone application to allow a community to monitor traffic noise in their environment, with focus on the night period and indoor measurement. Individuals, using mobile phones, provide data on characteristics of their dwellings and systematically record the level of noise inside their homes overnight. The records from multiple individuals are sent to a server, integrated into indicators and shared through mapping. The 2Loud? application is not designed to replace existing scientific measurements, but to add information which is currently not available. Noise measurements to assist the planning and management of traffic noise are normally carried out by designated technicians, using sophisticated equipment, and following specific guidelines for outdoors locations. This process provides very accurate records, however, for being a time consuming and expensive system, it results in a limited number of locations being surveyed and long time between updates. Moreover, scientific noise measurements do not survey inside dwellings. In this paper we present and discuss the participatory process proposed, and currently under implementation and test, to characterize the levels of exposure to traffic noise of residents living in the vicinity of highways in the City of Boroondara (Victoria, Australia) using the 2Loud? application

Pulsation and stabilization: Contractile forces that underlie morphogenesis

Embryonic development involves global changes in tissue shape and architecture that are driven by cell shape changes and rearrangements within cohesive cell sheets. Morphogenetic changes at the cell and tissue level require that cells generate forces and that these forces are transmitted between the cells of a coherent tissue. Contractile forces generated by the actin–myosin cytoskeleton are critical for morphogenesis, but the cellular and molecular mechanisms of contraction have been elusive for many cell shape changes and movements. Recent studies that have combined live imaging with computational and biophysical approaches have provided new insights into how contractile forces are generated and coordinated between cells and tissues. In this review, we discuss our current understanding of the mechanical forces that shape cells, tissues, and embryos, emphasizing the different modes of actomyosin contraction that generate various temporal and spatial patterns of force generation.American Cancer Society (grant PF-06- 143-01-DDC

Recycled aggregate concrete acoustic barrier

This document reports on a research project aimed at developing a concrete acoustic barrier made from Recycled Aggregate (RA) Concrete. The research project was undertaken in response to the needs expressed by the Victorian concrete recycling industry. The industry, the scientific community conducting research into relevant disciplines, and the community at large, represented by Victorian government agencies, are of the opinion that there is a need to devise a higher value utilisation application for selected concrete recycling products. This document outlines the rationale and objectives of the research project which involves the examination of Recycled Concrete (RC) Aggregate, the design and examination of RA Concrete, and finally the development of an acoustic barrier made from RA Concrete. The literature review presented in this report examines aspects of concrete recycling and concrete technology pertaining to traditional and alternative constituent materials for concrete production. Firstly, the importance and influence of fine and coarse aggregate on basic properties of concrete is introduced. Secondly, an account on the use of alternative materials in concrete technology, especially of coarse recycled aggregates and supplementary cementitious materials (SCM) is described. Thirdly, some of the physical and mechanical properties and how the use of RC Aggregate and SCM changes these properties are discussed. Fourthly, a number of commonly used techniques and neutron scattering techniques to investigate aggregate and concrete properties are introduced and discussed. Fifthly, the porosity of aggregate and concrete including durability are specifically discussed and testing methods are reasoned. The literature review also discusses the use of no-fines concrete; its physical, mechanical and acoustic properties. Finally it presents an account of the use of concrete in transportation traffic noise attenuation devices. This document continues with an outline of a methodology that was adopted in this research project. It outlines experimental work aimed at examining the properties of RC Aggregate which amongst other properties includes porosity, particle size distribution, water absorption, shape and density. It continues examining RA Concrete properties and includes, among other properties, compressive strength, porosity and durability as well as sound absorption of acoustic barrier. The methodology introduces standard and purposely modified test procedures used in the examination of aggregates, concrete and acoustic barrier. An account of various research techniques is presented, spanning from simple visual observations to more sophisticated neutron scattering techniques. The summary of test procedures follows a description of test specimen composition and their sizes, and a suite of tested specimens. It also introduces statistical methods used to analyse test results. After a detailed description of the aggregate, concrete and RA Concrete acoustic barrier, the document outlines a summary of data generated through the experimental program of this research project. The data on fine aggregate, on selected 14/10mm coarse RC Aggregate, on concrete made from natural and recycled aggregate and on acoustic barrier are presented and discussed. Test results of various physical, mechanical and acoustic properties of aggregate, concrete and barrier are reported, analysed and discussed. The data from observations, visual assessment and scientific experimentation of specific properties are then crossed analysed in a search for relationships between properties of fine and coarse aggregates and properties of concrete made from such aggregates. A cross analysis of data on 'less-fines' RA Concrete and on the acoustic performance of barrier is examined, and the relationship between the volume of interconnected voids in a porous part of 'less-fines' concrete, and the sound absorption of acoustic barrier is discussed and reported. The document then presents a synthesis of the literature review results, project aims adopted within the experimental program and test results in the three main areas of this research project. These areas include recycled concrete aggregate, recycled aggregate concrete and acoustic barrier made from RA Concrete. Finally, conclusions reached through the course of this investigation are summarised and recommendations are proposed in relation to the RA Concrete acoustic barrier. The main conclusion is that selected RC Aggregate can be used in the production of concrete of a compressive strength of 25MPa, if the moisture content and water absorption in the aggregate are closely monitored, and the foreign material content is kept below 1.5%. The author concludes that acoustic barrier made from selected RC Aggregate has unique sound absorption characteristics that can easily be tunable by a selection of appropriate aggregate and by specific concrete mix designs. Recommendations for further research are also proposed
