Within-subject intra- and inter-method consistency of two experimental risk attitude elicitation methods

We compare the consistency of choices in two methods to used elicit risk preferences on an aggregate as well as on an individual level. We asked subjects to choose twice from a list of nine decision between two lotteries, as introduced by Holt and Laury (2002, 2005) alternating with nine decisions using the budget approach introduced by Andreoni and Harbaugh (2009). We find that while on an aggregate(subject pool) level the results are (roughly) consistent, on an individual(within-subject) level,behavior is far from consistent. Within each method as well as across methods we observe low correlations. This again questions the reliability of experimental risk elicitation measures and the ability to use results from such methods to control for the risk aversion of subjects when explaining e�ects in other experimental games.

Toward a theory of the architectural subject

The extraordinary event, for Deleuze, is the object becoming subject – not in the manner of an abstract formulation, such as the substitution of one ideational representation for another but, rather, in the introduction of a vast, new, impersonal plane of subjectivity, populated by object processes and physical phenomena that in Deleuze’s discovery will be shown to constitute their own subjectivities. Deleuze’s polemic of subjectivity (the refusal of the Cartesian subject and the transcendental ego of Husserl) – long attempted by other thinkers – is unique precisely because it heralds the dawning of a new species of objecthood that will qualify as its own peculiar subjectivity. A survey of Deleuze’s early work on subjectivity, Empirisme et subjectivité (Deleuze 1953), Le Bergsonisme (Deleuze 1968), and Logique du sens (Deleuze 1969), brings the architectural reader into a peculiar confrontation with what Deleuze calls the ‘new transcendental field’, the field of subjectproducing effects, which for the philosopher takes the place of both the classical and modern subject. Deleuze’s theory of consciousness and perception is premised on the critique of Husserlian phenomenology; and ipso facto his question is an architectural problematic, even if the name ‘architecture’ is not invoked...

Behaviour and design of cold-formed steel beams subject to lateral-torsional buckling at elevated temperatures

Cold-formed steel beams are increasingly used as floor joists and bearers in buildings and often their behaviour and moment capacities are influenced by lateral-torsional buckling. With increasing usage of cold-formed steel beams their fire safety design has become an important issue. Fire design rules are commonly based on past research on hot-rolled steel beams. Hence a detailed parametric study was undertaken using validated finite element models to investigate the lateral-torsional buckling behaviour of simply supported cold-formed steel lipped channel beams subjected to uniform bending at uniform elevated temperatures. The moment capacity results were compared with the predictions from the available ambient temperature and fire design rules and suitable recommendations were made. European fire design rules were found to be over-conservative while the ambient temperature design rules could not be used based on single buckling curve. Hence a new design method was proposed that includes the important non-linear stress-strain characteristics observed for cold-formed steels at elevated temperatures. Comparison with numerical moment capacities demonstrated the accuracy of the new design method. This paper presents the details of the parametric study, comparisons with current design rules and the new design rules proposed in this research for lateral-torsional buckling of cold-formed steel lipped channel beams at elevated temperatures.

Statutory right to rescind contract remained available to buyer subject to specific performance decree

The aftermath of the Queensland floods of January 2011 continues to be played out in the courts. The effect of the floods on such a large scale has awakened the use of some statutory provisions that have not previously been litigated .Section 64 of the Property Law Act 1974 (Qld) is such a section. A version of this provision appears as s 34 of the Sale of Land Act 1982 (Vic). Broadly speaking, these sections permit a buyer of a dwelling house which has been damaged or destroyed between contract and completion to rescind the contract and recover their deposit provided that the rescission notice is given prior to "the date of completion or possession". The Court of Appeal decision of Dunworth v Mirvac Queensland Pty Ltd [2011] QCA 200 appears to be the first litigation upon the application of the section since it came into force in 1975.

The challenge of generic competences to science education

Since 2000 there has been pressure on education systems for develop in students a number of competences that are described as generic. This pressure stems from studies of the changing nature of work in the Knowledge Society that is now so dominant. The DeSeCo project identified a number of these competences, and listed them under the headings of communicative, analytical and personal. They include thinking, creativity, communication skills, knowing how to learn, working in teams, adapting to change, and problem solving. These competences pose a substantial challenge to the manner in which education as a whole, and science education in particular, has hitherto been generally conceived. It is now common to find their importance acknowledged in new formulation of the curriculum. The paper reviews a number of these curriculum documents and how they have tried to relate these competences to the teaching and learning of Science, a subject with its own very specific content for learning. It will be suggested that the challenge provides an opportunity for a reconstruction of the teaching and learning of science in schools that will increase its effectiveness for more students.

Influence of damping systems on building structures subject to seismic effects

This paper investigates the response of multi-storey structures under simulated earthquake loads with friction dampers, viscoelastic dampers and combined friction-viscoelastic damping devices strategically located within shear walls. Consequently, evaluations are made as to how the damping systems affect the seismic response of these structures with respect to deflections and accelerations. In particular, this paper concentrates on the effects of damper types, configurations and their locations within the cut-outs of shear walls. The initial stiffness of the cut out section of the shear wall is removed and replaced by the stiffness and damping of the device. Influence of parameters of damper properties such as stiffness, damping coefficient, location, configuration and size are studied and evaluated using results obtained under several different earthquake scenarios. Structural models with cut outs at different heights are treated in order to establish the effectiveness of the dampers and their optimal placement. This conceptual study has demonstrated the feasibility of mitigating the seismic response of building structures by using embedded dampers.

Cold-formed steel columns subject to local buckling at elevated temperatures

Fire safety design of building structures has received greater attention in recent times due to continuing losses of properties and lives in fires. However, the structural behaviour of thin-walled cold-formed steel columns under fire conditions is not well understood despite the increasing use of light gauge steels in building construction. Cold-formed steel columns are often subject to local buckling effects. Therefore a series of laboratory tests of lipped and unlipped channel columns made of varying steel thicknesses and grades was undertaken at uniform elevated temperatures up to 700°C under steady state conditions. Finite element models of the tested columns were also developed, and their elastic buckling and nonlinear analysis results were compared with test results at elevated temperatures. Effects of the degradation of mechanical properties of steel with temperature were included in the finite element analyses. The use of accurately measured yield stress, elasticity modulus and stress-strain curves at elevated temperatures provided a good comparison of the ultimate loads and load-deflection curves from tests and finite element analyses. The commonly used effective width design rules and the direct strength method at ambient temperature were then used to predict the ultimate loads at elevated temperatures by using the reduced mechanical properties. By comparing these predicted ultimate loads with those from tests and finite element analyses, the accuracy of using this design approach was evaluated.

Improved design rules for fixed ended cold-formed steel columns subject to flexural-torsional buckling

This paper has presented the details of an investigation into the flexural and flexuraltorsional buckling behaviour of cold-formed structural steel columns with pinned and fixed ends. Current design rules for the member capacities of cold-formed steel columns are based on the same non-dimensional strength curve for both fixed and pinned-ended columns. This research has reviewed the accuracy of the current design rules in AS/NZS 4600 and the North American Specification in determining the member capacities of cold-formed steel columns using the results from detailed finite element analyses and an experimental study of lipped channel columns. It was found that the current Australian and American design rules accurately predicted the member capacities of pin ended lipped channel columns undergoing flexural and flexural torsional buckling. However, for fixed ended columns with warping fixity undergoing flexural-torsional buckling, it was found that the current design rules significantly underestimated the column capacities as they disregard the beneficial effect of warping fixity. This paper has therefore proposed improved design rules and verified their accuracy using finite element analysis and test results of cold-formed lipped channel columns made of three cross-sections and five different steel grades and thicknesses.

Developing and delivering a software internationalisation subject

This paper describes the content and delivery of a software internationalisation subject (ITN677) that was developed for Master of Information Technology (MIT) students in the Faculty of Information Technology at Queensland University of Technology. This elective subject introduces students to the strategies, technologies, techniques and current development associated with this growing 'software development for the world' specialty area. Students learn what is involved in planning and managing a software internationalisation project as well as designing, building and using a software internationalisation application. Students also learn about how a software internationalisation project must fit into an over-all product localisation and globalisation that may include culturalisation, tailored system architectures, and reliance upon industry standards. In addition, students are exposed to the different software development techniques used by organizations in this arena and the perils and pitfalls of managing software internationalisation projects.

Tragedy and assimilation : reciprocity between surface and subject

Here we unveil a tragic triptych of three Australian women painfully painted onto the walls of interior surfaces. The woman at the centre of the triptych is Florence Broadhurst whose tragic death still remains a mystery. To the right is Australian skin illustrator Emma Hack who recreates Broadhurst’s wallpapers, mimicking their colourful patterns onto live models. Hack perfectly assimilates the models’ body into the wallpaper, camouflaging bodies except for small hints at something more in the foreground. In the process of Hack’s images, the models become statues, standing painfully still holding their breath for minutes at a time. The third woman, to the left of the triptych, is the fictional character Candy from the 2006 Australian film Candy. Candy’s traumatic struggle with addiction ends with her conveying her pain in a poem she writes on the walls of her home; culminating her tragic story into a disturbed domestic wall surface. This research tries to understand this relationship with the surface through tragedy as a reciprocal agreement between surface and subject and not a permanent transference between one state and another. What the surface provides in times of personal struggle and turmoil is a method for us to come to terms with out material existence.

Analytical benchmark solutions for steel frame structures subject to local buckling effects

Application of "advanced analysis" methods suitable for non-linear analysis and design of steel frame structures permits direct and accurate determination of ultimate system strengths, without resort to simplified elastic methods of analysis and semi-empirical specification equations. However, the application of advanced analysis methods has previously been restricted to steel frames comprising only compact sections that are not influenced by the effects of local buckling. A research project has been conducted with the aim of developing concentrated plasticity methods suitable for practical advanced analysis of steel frame structures comprising non-compact sections. This paper contains a comprehensive set of analytical benchmark solutions for steel frames comprising non-compact sections, which can be used to verify the accuracy of simplified concentrated plasticity methods of advanced analysis. The analytical benchmark solutions were obtained using a distributed plasticity shell finite element model that explicitly accounts for the effects of gradual cross-sectional yielding, longitudinal spread of plasticity, initial geometric imperfections, residual stresses, and local buckling. A brief description and verification of the shell finite element model is provided in this paper.

Why ADR must be a mandatory subject in the law degree - the profession

The Australian legal profession, as well as the content and pedagogy of legal education across Australia, are steeped in tradition and conservatism. Indeed, the legal profession and our institutions of legal education are in a relationship of mutual influence which leaves the way we teach law resistant to change. There has traditionally been pushback against the notion that dispute resolution should have a place amongst black letter law subjects in the legal curriculum. This paper argues that this position cannot be maintained in the modern legal climate. We challenge legal education orthodoxy and promote NADRAC’s position that alternative dispute resolution should be a compulsory, stand alone subject in the law degree. We put forward ten simple arguments as to why every law student should be exposed to a semester long course of DR instruction.

Why ADR must be a mandatory subject in the law degree - the academy

The profession of law is deeply steeped in tradition and conservatism. The content and pedagogy employed in law faculties across Australia is similarly steeped in tradition and conservatism. Indeed, the practice of law and our institutions of legal education are in a relationship of mutual influence; a dénouement which preserves the best aspects of our common law legal system, but also leaves the way we educate, practice, and think about the role of law, resistant to change. In this article, we lay down a challenge to legal education orthodoxy and a call to arms for legal academic progressivists. It is our simple argument that alternative dispute resolution should be a compulsory, stand alone subject in the law degree. There has been traditional pushback against the notion that alternative dispute resolution should have a place amongst black letter law subjects in the legal curriculum. This position cannot be maintained in the modern day legal climate. We put forward ten simple arguments as to why every law student should be exposed to a semester long course of ADR instruction. With respect to relationships of mutual influence, whether legal education should assimilate the practise of law, or shape the practise of law makes no difference here. Both views necessitate the inclusion of ADR as a compulsory subject in the law degree.
