Best Practice In Online Assessment: Principles, Processes And Outcomes, Catherine E Mcloughlin, Joseph Luca Jan 2006

Best Practice In Online Assessment: Principles, Processes And Outcomes, Catherine E Mcloughlin, Joseph Luca

Research outputs pre 2011

Instead of using narrowly defined learning outcomes tested by examinations, technology offers a total environment where real life skills, such as written and verbal communication, collaboration and team work can be assessed by the team and tutor by giving learners multiple channels of expression, such as visualisation, multimedia presentations, audio and video resources. Thus, information technologies are closely inter-woven with the quality of the learning experience, and can be used to create authentic tasks for assessment. The paper presents several examples of authentic assesment utising information and communications technology.

A Faster Algorithm For Calculating Hypervolume, Lyndon While, Philip Hingston, Luigi Barone, Simon Huband Jan 2006

A Faster Algorithm For Calculating Hypervolume, Lyndon While, Philip Hingston, Luigi Barone, Simon Huband

Research outputs pre 2011

We present an algorithm for calculating hypervolume exactly, the Hypervolume by Slicing Objectives (HSO) algorithm, that is faster than any that has previously been published. HSO processes objectives instead of points, an idea that has been considered before but that has never been properly evaluated in the literature. We show that both previously studied exact hypervolume algorithms are exponential in at least the number of objectives and that although HSO is also exponential in the number of objectives in the worst case, it runs in significantly less time, i.e., two to three orders of magnitude less for randomly generated and …

Fixture-Scheduling For The Australian Football League Using A Multi-Objective Evolutionary Algorithm, Luigi Barone, Lyndon While, Paul Hughes, Philip Hingston Jan 2006

Fixture-Scheduling For The Australian Football League Using A Multi-Objective Evolutionary Algorithm, Luigi Barone, Lyndon While, Paul Hughes, Philip Hingston

Research outputs pre 2011

AFL football is a team sport that entertains millions and contributes a huge amount of money to the Australian economy. Scheduling games in the AFL is difficult, as a number of different, often conflicting, factors must be considered. In this paper, we propose the use of a multi-objective evolutionary algorithm for determining such a schedule. We detail the technical details needed to apply a multi-objective evolutionary algorithm to this problem and report on experiments that show the effectiveness of this approach. Comparison with actual schedules used in the AFL demonstrates that this approach could make a useful contribution.

Opto-Vlsi-Based Correlator Architecture For Multiwavelength Optical Header Recognition, Muhsen Aljada, Kamal E. Alameh, Khalid Al-Begain Jan 2006

Opto-Vlsi-Based Correlator Architecture For Multiwavelength Optical Header Recognition, Muhsen Aljada, Kamal E. Alameh, Khalid Al-Begain

Research outputs pre 2011

A novel optical correlator employing an opto-very-large-scale-integration (VLSI) processor to construct the routing lookup table, in conjunction with an array of fiber Bragg gratings (FBGs) for multiwavelength optical header recognition is demonstrated. The FBG array provides wavelength-dependent time delays, whereas the opto-VLSI processor generates wavelength intensity profiles that match arbitrary bit patterns. The recognition of 4-b optical patterns is experimentally demonstrated at 2.2 Gb/s by showing that the correlator produces an autocorrelation waveform of high peak whenever the input bit pattern matches the wavelength intensity profile.

Dynamic Optical Comb Filter Using Opto-Vlsi Processing, Zhenglin Wang, Kamal Alameh, Rong Zheng, Chung Poh Jan 2006

Dynamic Optical Comb Filter Using Opto-Vlsi Processing, Zhenglin Wang, Kamal Alameh, Rong Zheng, Chung Poh

Research outputs pre 2011

Reconfigurable multi-channel optical filters are presented in this paper. The operation principle of the reconfigurable filter is based on the dynamic beam steering capacity of Opto-VLSI processor in conjunction with a high dispersion free space grating. The dispersion grating separates the input signal spectrum while the Opto-VLSI processor is driven by optimised phase holograms to dynamically select the wavelengths to be coupled into the output port. Experimental results show that up to 8 bands can be synthesised, with a wavelength tuning span of 10 nm and a 3dB bandwidth less than 0.5nm.

Paramedics And Pre-Hospital Management Of Acute Myocardial Infarction: Diagnosis And Reperfusion, Steven Johnston, Richard Brightwell, Melanie Ziman

Research outputs pre 2011

In this paper, we discuss and critically analyse pre-hospital management of acute myocardial infarction (AMI). It is clear from several large studies that rapid diagnosis and application of thrombolysis reduces morbidity and mortality rates. Strategies that improve time to treatment in the pre-hospital setting are therefore of fundamental importance in the management of this fatal disease. The advantage of 12 lead electrocardiography use by paramedics to diagnose AMI and reduce time to treatment is discussed. Moreover, paramedic application of thrombolysis in the pre-hospital environment is examined. Several studies conducted worldwide support the notion that ambulance services can play a role …

Producing Safety: Evaluating Structuration Theory As A Framework For Exploring The Values In Action Within The Civil Construction Industry In Wa, Susanne Bahn, Llandis Barratt-Pugh Jan 2006

Producing Safety: Evaluating Structuration Theory As A Framework For Exploring The Values In Action Within The Civil Construction Industry In Wa, Susanne Bahn, Llandis Barratt-Pugh

Research outputs pre 2011

In this paper we argue that occupational safety and health (OS&H) in the workplace is a production of values in action. We propose that such relations may best be explored through the structuration lens generated by Giddens (1984). We both use structuration theory to conceptualise the relations that produce safety and evaluate the utility of the theory as a research framework. We provide a detailed discussion of the context of, and rationale for a proposed study. The paper then analyses the components of structuration theory and frames the production of safety within these conceptual relations. The paper argues that the …
