Measuring the performance of a regional cluster in innovation facilitation

Regional industry clusters have been promoted for several years as effective mechanisms to assist firms become more innovative and more competitive. But do they really achieve this goal, and more importantly, just how should an assessment of cluster performance in supporting and facilitating innovation within its members, be undertaken? In this paper we report on a study of a regional IT cluster in Western Sydney, Australia, develop some criteria for assessing the innovation facilitation performance of industry clusters, and discuss the cluster in relation to these criteria. We suggest that engagement with a cluster may enhance the innovation capacity of a firm, and the type of required innovation support varies significantly with the maturity and absorptive capacity of individual firms.

Students' approaches to assessment in accounting education : the unique student perspective

In accounting education, most Student Approaches to Learning (SAL) research has investigated the relationship between students' performance and their approaches to learning. Relatively limited research has been conducted on how assessment practices influence the quality of students' learning from the students' perspective. This paper seeks to address this gap in the accounting education literature. The research is centred on a large Australian undergraduate accounting degree delivered in Australia, Singapore and Hong Kong. Focus group interviews were conducted with students across the three locations. The research results reveal that: (1) it is the English competency of students that has the most important impact on students' completion of set assessment tasks and thus their approach to learning; (2) it is the way in which assessment is designed and written and the way lecturers convey their expectations about how assessment will be undertaken that is crucial to how students from various countries perform in that assessment; and (3) students' approaches to assessment and their preferred assessment tasks are not homogeneously based on cultural background.

Hidden stories : listening to the audience at the live performance

This paper explores how audiences describe and evaluate their experience of a live performance. Much of the arts marketing literature measures audience satisfaction with the entire event, including pre and post show talks, parking, ticket price, seating, merchandise and refreshments. Research undertaken at a range of live performing arts events in 2008 and 2009 revealed ‘hidden stories’ of audience members’ responses to performances. These responses are indicative of four aspects of the audience experience – knowledge, risk, authenticity and collective engagement. The stories, and their indicators, are the audience measure of quality of performance. This paper uses audience research at three contemporary theatre companies, to test and validate the audience experience as a new quality assessment instrument: the Arts Audience Experience Index.

Guided wave propagation and spectral element method for debonding damage assessment in RC structures

A concrete–steel interface spectral element is developed to study the guided wave propagation along the steel rebar in the concrete. Scalar damage parameters characterizing changes in the interface (debonding damage) are incorporated into the formulation of the spectral finite element that is used for damage detection of reinforced concrete structures. Experimental tests are carried out on a reinforced concrete beam with embedded piezoelectric elements to verify the performance of the proposed model and algorithm. Parametric studies are performed to evaluate the effect of different damage scenarios on wave propagation in the reinforced concrete structures. Numerical simulations and experimental results show that the method is effective to model wave propagation along the steel rebar in concrete and promising to detect damage in the concrete–steel interface.

Reflexive capability maturity assessment for firm management of multipartner international projects

This paper reports the findings of a research project which was aimed at developing and promoting a greater understanding of the uniqueness of successful Australian-Malaysian partnerships and joint ventures undertaken on complex multi-partner mega construction projects. The aim of the investigation was to identify the critical success factors specific to such partnerships. The theoretical framework was grounded in a previous empirical study on design firm internationalisation which demonstrated that long-term success in international markets is enhanced by the management of integration of transformation of social, cultural and intellectual capital within the firm. A generic adaptive performance framework mapping the key performance indicators for each of these dimensions was developed which can be modified to unique contexts related to specific geographical localities. In the Australian Malaysian Institute study the framework is tested within the context of firm and shared partnership capital. The broad interpretive framework of adaptive performance was refined as a result of the findings of the four case studies of Malaysian organisations to develop a partnerships capacity performance measurement framework for Malaysian firms working on international projects. Six in-depth interviews were conducted with ten participants across the four Malaysian firms and a thematic analysis was undertaken of the transcripts. A reflexive capability maturity assessment tool was developed from insights gained into the underlying causes of key barriers coupled with common themes emerging in relation to the successful approaches used by case study firms to overcome those barriers. Specific examples of the case study firms' demonstration of reflexive capability in the areas of market knowledge, design management and market entry are presented.

Potential utilisation of assessment centre methodology to enhance student placement outcomes, experiences and employability

Background: Placements are of particular importance due to the richness of learning associated with placement experiences and the wider links they represent to industry and the community. Students often refer to placements as the most significant, productive and memorable component of their training. Importantly, placements also provide the opportunity for students to become work ready, i.e., integrate their knowledge into a new set of employable skills and personal qualities. There is now increased emphasis on employability by employers and universities alike; in fact, it now represents a critical performance measure for Australian universities. Despite these key points, there appears to be inconsistencies in approaches to maximising work placements across and within Universities. Assessment centre methodology may represent a useful approach to standardise and optimise work placements for all stakeholders. Assessment centre methodology has been used successfully for selection purposes in industry for the past 50 years. However, their use as a developmental tool is less prominent. Furthermore, their application in the higher education setting, particularly in the context of placements and student development appears under researched.
Overview of issue: Only one published study was found that reported the use of a developmental assessment centre with a post-graduate sample. That study took place over 10 years ago when the concept of employability was still gaining recognition and work placements were less common. The current paper reviews this unique concept in the context of the existing literature and the current needs of Universities, employers and students.
Discussion: It is argued that the reconsideration of assessment centre methodology for development represents an innovative approach to consistently maximising work placement outcomes, experiences and employability.
Conclusions: Given the importance and increased use of placements, the application of assessment centre methodology within the placement curriculum warrants further research. This methodology represents a standardised approach for implementation within a range of placement programs to enhance student development, placement outcomes and employability.

Portfolios, performance and authenticity

This text reviews literature on authentic assessment in the context of Australian education over the last twenty years. It examines the practices advocated for beginning teachers as assessors of students and the key issue of authentic assessment of teachers themselves.

Evaluation of the use of Assessment Centre methodology to enhance development planning, work placement outcomes and work readiness for postgraduate students : a pilot

Background: Placements as a form of Work Integrated Learning are widely recognised for the positive impact they have on improving student employability and work readiness. Students can maximise strengths, improve areas of weakness, and develop a strong understanding of the requirements of their chosen field within the confines of a well monitored and rich learning environment. Assessment Centres (ACs) are commonly used in corporate settings for recruitment, selection and more recently to provide developmental feedback to participants. Based on a recent literature review, the present the present project evaluates the application of AC methodology as a developmental tool within the placement milieu. The review, which is also included the current conference proceedings details the benefits of utilising the AC process forming the impetus for the present pilot (Sturre; von Treuer & Keele 2010).
Aims: The primary aim of the paper was to evaluate the application of AC methodology as a tool for measuring and subsequently enhancing professional competencies in a sample of postgraduate students in organisational psychology (n=15).
Method: A longitudinal design was utilised with numerous evaluation points from placement stakeholders. This paper presents the first wave of findings. Students undertook a range of activities, including an in-tray exercise, role play, written report, leaderless group discussion and a personality assessment. Comprehensive feedback was provided by organisational psychologists who also fulfil the role of placement co-ordinators. With the assistance of Placement Co-ordinators, students prepared development plans relating to the competencies identified as requiring development. These plans were to be addressed and progress monitored during consecutive placements.
Results: Initial perceptions gathered from students regarding the AC process were very encouraging. Performance
evaluations collected to date, as measured by behaviourally based ratings scales completed by the students themselves and their workplace supervisors illustrate the positive effect of this methodology. The rigour and comprehensive techniques offered by the methodology enabled students to focus on and improve areas identified for development.
Conclusions: It is important to note that the present design formed a pilot study and as mentioned was undertaken with a limited sample. Future implementation is planned with larger samples, enabling a more comprehensive analysis of the methodology. Nevertheless, the methodology appears to provide a much needed strategy for the assessment and ongoing development of students prior to and during work placements. The application provides early intervention enabling students to address development needs with input from both university and organisational stakeholders based on an established, standardised process.

Student peer and self assessment in the context of work integrated learning : making it work

Students are now experiencing opportunities in practice education where their learning is facilitated by professionals of varied backgrounds thus leading to issues of how to assess student performance while on placement. Educators have had to re-think the way in which students’ performance is assessed and to integrate the key graduate attributes of critical reflection, self and peer assessments and feedback. Using recommendations by Mason (1999) in relation to a collaborative group model for workplace learning and ‘The Self-Directed Learning Model’ by Gaiptman and Anthony (1989) the Occupational Wellness and Life Satisfaction (OWLS) program encourages students to reflect on their experiences in an environment of self and peer evaluation, focussing on the process of learning rather than purely on outcomes. Students are required to complete a self and peer assessment of their learning using a nationally recognised fieldwork evaluation instrument and develop a practice portfolio consisting of learning contract and supporting evidence for their self-assessment. Qualitative and quantitative data was collected via a questionnaire to alumni. The most frequently identified skills that were valued by respondents were autonomy and independence. Other benefits identified were facilitation of self directed learning, and ability to problem solve with colleagues and to share learning. In a higher education environment where lifelong learning and the ability to work collaboratively are valued graduate attributes, a focus on peer and self assessment within the context of work integrated learning contributes to graduates who are well placed to work in both traditional and newer and emerging areas of practice.

Machinability assessment and surface integrity characteristics of Austempered Ductile Iron (ADI) using ultra-hard cutting tools

The application of austempered ductile iron (ADI) is gaining an ever greater share of the worldwide ferrous product market, specifically centering on the aerospace, automotive and shipping industries. ADI is a heat treated cast iron, which exhibits remarkable mechanical properties and provides an attractive material for designers and engineers to displace conventional materials. Previous attempts, however, to machine ADI using carbide or ceramic cutting tools produced poor tool life characteristics due to the relatively poor machinability of the workpiece. This paper presents a research study that has applied the advanced technology of modern ultrahard cutting tools, in an attempt to achieve enhanced machinability performance. This performance was evaluated through the analysis of cutting forces, tool wear, surface finish and roundness.

Evaluating cutting fluid machinability performance

Changes in the metal-working industry, as a result of new environmental legislation or health and safety initiatives, creates the need for constant re-formulation of soluble cutting fluids. In order for there to be confidence in the product's ability to perform its required function successfully, there must be some clearly defined test methods for assessing machinability. Such a test methodology must provide comprehensive data on the fluid's lubrication and cooling properties, which are likely to occur in application. This paper describes the functions of soluble cutting fluids and discusses ways in which performance has been previously determined. Furthermore, it presents a new method for assessing machinability which is proposed as the basis for the development of a new and universal test protocol.

A comparative assessment of austempered ductile iron as a substitute in weight reduction applications

Manufacturing engineering has had to undergo drastic changes in the approach to material selection in order to meet new design challenges. In the automotive industry, researchers in their effort to reduce emissions and satisfy environmental regulations, have shifted their focus to new emerging materials such as high-strength aluminium alloys, metal matrix composites, plastics, polymers and of late, Austempered Ductile Iron (ADI). ADI is a good choice for design where the criterion is high performance at reduced weight and cost. The unique, ausferrite microstructure gives the material desirable material properties and an edge over other materials. A comparative study of ADI in terms of materials properties and machining characteristics with other materials is desirable to highlight the potential of the material. This paper focuses on a comparative assessment of material and machining characteristics of ADI for different applications. The properties under consideration are machinability, weight and cost savings and versatility. ADI has a higher strength-to-weight ratio than aluminium making it a ready alternative for material selection. In terms of machinability, there are some problems associated with machining of ADI due to its work hardening nature. This paper attempts to identify the possible potential applications of ADI, by critically reviewing specific applications such as machinability, overall economics and service.

Baseline measurements on the performance of four constructed wetlands in tropical Australia

Constructed wetlands provide several benefits that are not solely limited to storm water management and are becoming common in storm water management. In this research, four recently constructed wetlands underwent in situ and laboratory water sampling to determine their efficiency in removing storm water pollutants over a 5-month period. From the sampling results, it was determined that each of the wetlands was able to reduce the concentration of pollutants in the stormwater. To aid in the assessment of the wetlands against each other, a model was developed to determine the extent of removal of stormwater pollutants over the length of the wetland. The results from this model complimented the data collected from the field. Improvements, such as increased amounts of vegetation were recommended for the wetlands with the aim of increasing the effectiveness. Further investigations into the wetlands will allow for better understanding of the wetland's performance.

Assessment of spatiotemporal varying relationships between rainfall, land cover and surface water area using geographically weighted regression

Traditional regression techniques such as ordinary least squares (OLS) are often unable to accurately model spatially varying data and may ignore or hide local variations in model coefficients. A relatively new technique, geographically weighted regression (GWR) has been shown to greatly improve model performance compared to OLS in terms of higher R 2 and lower corrected Akaike information criterion (AICC). GWR models have the potential to improve reliabilities of the identified relationships by reducing spatial autocorrelations and by accounting for local variations and spatial non-stationarity between dependent and independent variables. In this study, GWR was used to examine the relationship between land cover, rainfall and surface water habitat in 149 sub-catchments in a predominately agricultural region covering 2.6 million ha in southeast Australia. The application of the GWR models revealed that the relationships between land cover, rainfall and surface water habitat display significant spatial non-stationarity. GWR showed improvements over analogous OLS models in terms of higher R 2 and lower AICC. The increased explanatory power of GWR was confirmed by the results of an approximate likelihood ratio test, which showed statistically significant improvements over analogous OLS models. The models suggest that the amount of surface water area in the landscape is related to anthropogenic drainage practices enhancing runoff to facilitate intensive agriculture and increased plantation forestry. However, with some key variables not present in our analysis, the strength of this relationship could not be qualified. GWR techniques have the potential to serve as a useful tool for environmental research and management across a broad range of scales for the investigation of spatially varying relationships.

Optimising the life cycle energy performance of residential buildings

A holistic approach to low-energy building design is essential to ensure that any efficiency improvement strategies provide a net energy benefit over the life of the building. Previous work by the authors has established a model for informing low-energy building design based on a comparison of the life cycle energy demand associated with a broad range of building assemblies. This model ranks assemblies based on their combined initial and recurrent embodied energy and operational energy demand. The current study applies this model to an actual residential building in order to demonstrate the application of the model for optimising a building’s life cycle energy performance. The aim of this study was to demonstrate how the availability of comparable energy performance information at the building design stage can be used to better optimise a building’s energy performance. The life cycle energy demand of the case study building, located in the temperate climate of Melbourne, Australia, was quantified using a comprehensive embodied energy assessment technique and TRNSYS thermal energy simulation software. The building was then modelled with variations to its external assemblies in an attempt to optimise its life cycle energy performance. The alternative assemblies chosen were those shown through the author’s previous modelling to result in the lowest life cycle energy demand for each building element. The best performing assemblies for each of the main external building elements were then combined into a best-case scenario to quantify the potential life cycle energy savings possible compared to the original building. The study showed that significant life cycle energy savings are possible through the modelling of individual building elements for the case study building. While these findings relate to a very specific case, this study demonstrates the application of a model for optimising building life cycle energy performance that may be applied more broadly during early-stage building design to optimise life cycle energy performance.
