Less Than Equal: Secularism, Religious Pluralism And Privilege, Anne Aly, Lelia Rosalind Green

Research outputs pre 2011

In its preamble, The Western Australian Charter of Multiculturalism (WA) commits the state to becoming: “A society in which respect for mutual difference is accompanied by equality of opportunity within a framework of democratic citizenship”. One of the principles of multiculturalism, as enunciated in the Charter, is “equality of opportunity for all members of society to achieve their full potential in a free and democratic society where every individual is equal before and under the law”. An important element of this principle is the “equality of opportunity ... to achieve ... full potential”. The implication here is that those who …

Optimized Wlan Mac Protocol For Multimedia Applications, Hushairi Zen, Daryoush Habibi, Alexander Rassau, Iftekhar Ahmad

Research outputs pre 2011

In this paper we propose an optimized WLAN MAC protocol for multimedia applications. The proposed MAC protocol consist of 3 main optimizing architectures, traffic segregation, specific service interval (SI) for voice and video traffic and smaller contention window (CW). Traffic segregation segregates real-time traffic from best-effort traffic while specific service interval provides voice and video traffic with the SI based on its mean arrival rate. In the contention time frame, the CW is made smaller to reduce delay and increase throughput. Ns2 is used as a simulating tool to compare the results of our proposed protocol with the legacy 802.11 …

Magnetic Field Sensors And Visualizers Using Magnetic Photonic Crystals, Mikhail Vasiliev, Kamal Alameh, Viatcheslav Kotov

Research outputs pre 2011

Magneto-optical imaging is widely used to observe the domain patterns in magnetic materials, visualize defects in ferromagnetic objects, and measure the spatial distribution of stray magnetic fields. Optimized 1D magneto-photonic crystals enable a significant increase in the sensitivity of magneto-optical sensors. The properties of such devices based on the optimized reflection (doubled Faraday rotation) mode and the use of 1D magnetic photonic crystals as sensors are discussed. Experimental results of the fabrication and characterization of ferrite-garnet layers possessing uniaxial magnetic anisotropy are shown, and an optimized film structure suitable for magneto-optical imaging is proposed.

A novel reconfigurable microwave photonic filter structure with positive and negative coefficients is proposed and demonstrated. The filter structure comprises two arrayed waveguide gratings, a custom-made fiber array, high-dispersion fibres, and a reconfigurable opto-VLSI processor. Positive and negative filter weights can flexibly be synthesised to realise arbitrary transfer functions. Experimental results are presented, which demonstrate the principle of the proposed filter structure.

Pax7 Is Requisite For Maintenance Of A Subpopulation Of Superior Collicular Neurons And Shows A Diverging Expression Pattern To Pax3 During Superioir Collicular Development, Jennifer Thompson, Andreas Zembrzycki, Ahmed Mansouri, Melanie Ziman

Research outputs pre 2011

Pax7 encodes a transcription factor well-established as an important determinant of mesencephalic identity and superior collicular development. Pax7 mutant mice, however, present with no obvious morphological impairments to the superior colliculus. This finding is paradoxical and has been attributed to functional redundancy afforded by its paralogue Pax3. Here we utilise Pax7 mutant mice to investigate the precise role of this important developmental regulator during superior collicular development and neuronal specification/differentiation. We also assess its spatiotemporal relationship with Pax3 during embryonic development. Analysis of the superior colliculus of Pax7 mutant and wildtype mice at a variety of developmental timepoints revealed that …

Organisational Survey: Impact Of Healthway Funding On Currently Funded And Previously Funded Sar Organisations, Michael Rosenberg, Sarah French, Jenna Mitchell, Christina Mills, Lisa Wood

Research outputs pre 2011

Since 1992, organisations in receipt of Healthway funding have demonstrated consistently high levels of commitment to sponsorship requirements. In part, the high levels of commitment observed may reflect a trend towards organisations with similar values to Healthway applying for funding. Organisations with different values to Healthway may receive funding once and decide that the sponsorship does riot match the needs of their organisation. This may result in difficulties fo.r Healthway to access hard to reach organisations, or to establish longer-term partnerships with Sports, Arts or Racing (SAR) organisations that target high priority groups. To better understand how Healthway's requirements of …

Towards Automated Test Sequence Generation, Usman Farooq, Chiou Peng Lam, Huaizhong Li

Research outputs pre 2011

The article presents a novel control-flow based test sequence generation technique using UML 2.0 activity diagram, which is a behavioral type of UML diagram. Like other model-based techniques, this technique can be used in the earlier phases of the development process owing to the availability of the design models of the system. The activity diagram model is seamlessly converted into a colored Petri net. We proposed a technique that enables the automatic generation of test sequences according to a given coverage criteria from the execution of the colored Petri nets model. Two types of structural coverage criteria for AD based …

Historical Datasets Of Dugong (Dugong Dugon) Observations In The Kimberley Region Of Western Australia - Data Report - Report No. 2008-03, David K. Holley, R. I.T. Prince

Research outputs pre 2011

Research Need and Objective :

Many sections of the northern WA coastline have become heavily industrialised in the last three decades particularly throughout the Pilbara region where offshore and onshore oil and gas exploration and processing facilities are abundant. There have been recent moves to develop similar industry along the Kimberley coast to access the Browse Basin, a 140,000 Km2 offshore gas field approximately 300km off the Kimberley Coast. This has resulted in extensive debate and the need to define the natural values of this region, which is considered to be one of the world’s most ecologically diverse (WWF 2008). …

Analysis Of Information Remaining On Hand Held Devices For Sale On The Second Hand Market, Andrew Jones, Craig Valli, Iain Sutherland

Research outputs pre 2011

The ownership and use of mobile phones, Personal Digital Assistants and other hand held devices is now ubiquitous both for home and business use. The majority of these devices have a high initial cost, a relatively short period before they become obsolescent and a relatively low second hand value. As a result of this, when the devices are replaced, there are indications that they tend to be discarded. As technology has continued to develop, it has led to an increasing diversity in the number and type of devices that are available, and the processing power and the storage capacity of …

Interviewers' Sensitivity To Impression Management Tactics In Structured Interviews, Filip Lievens, Helga Peeters

Research Collection Lee Kong Chian School Of Business

This study examines interviewers' sensitivity to impression management in structured interviews by determining the relative importance that interviewers attach to ( verbal and nonverbal) impression management as compared to the relative importance that they attach to predetermined competencies. Two samples of interviewers ( 55 Master I/O psychology students and 18 professional interviewers) watched and evaluated videotaped interviewees who were instructed to put their best foot forward. Results of relative weight analyses showed that the importance of verbal and nonverbal impression management tactics was relatively small as compared to the importance attached to job-related competencies. The type of interview format had …

A Closer Look At The Relationship Between Justice Perceptions And Feedback Reactions: The Role Of The Quality Of The Relationship With The Supervisor, Marjolein Feys, Nele Libbrecht, Frederik Anseel, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Two field studies were undertaken to investigate the nature of the relationship between justice perceptions and feedback reactions. Previous work Suggests that the relationship between procedural justice and feedback reactions is mediated by the quality of the relationship with the supervisor. However, there are also good theoretical reasons to hypothesise that the relationship between justice perceptions and feedback reactions is moderated by relationship quality. Across two field studies, we found Support for both mediated and moderated relationships. Results of the moderator analyses showed that the positive relationship between justice perceptions and feedback reactions was more pronounced for subordinates in a …

Rethinking The Role Of Management Consultants As Disseminators Of Business Knowledge: Knowledge Flows, Directions, And Conditions In Consulting Projects, Andrew Sturdy, Karen Handley, Timothy Adrian Robert Clark, Robin Fincham

Research Collection Lee Kong Chian School Of Business

Consultants are seen as core agents in the dissemination of business knowledgethrough their relative expertise and/or rhetorical and knowledge management practices.However, relatively few studies focus specifically on their role in projects with clientorganisations. This paper examines knowledge flow in consultancy projects fromlongitudinal observation and interview research as well as a survey of clients andconsultants working together. Our analysis suggests that the conventional view ofconsultants as disseminators of new management ideas to clients is, at best,exaggerated and certainly misrepresents their role in project work. Firstly, it tends tooccur by default rather than by design. More importantly however, learning is oftenconcerned with …
