Cracking the Code: a Checklist to Complement CRAs for First Year Justice Students

Project overview, promotional poster and how to access and use the checklist (student guide)

Submission to Communications Alliance Industry Code: Copyright Notice Scheme

In making this submission, we suggest that Australia learn from the experiences of other jurisdictions, and avoid some of the mistakes that have been made. In particular, this involves: * Ensuring that adequate information is available to evaluate the success of the scheme * Ensuring that notices sent to consumers provide full and accurate information that helps them understand their rights and options * Limiting the potential abuse of the system, and particularly attempts to intimidate consumers into paying unfair penalties through ‘speculative invoicing’ * Avoiding the potential for actual or perceived bias in the scheme’s oversight body

MATLAB/Simulink simulation and C2000 code generation model for a grid-interactive 3-phase 4-wire inverter

This work is a MATLAB/Simulink model of a controller for a three-phase, four-wire, grid-interactive inverter. The model provides capacity for simulating the performance of power electroinic hardware, as well as code generation for an embedded controller. The implemented hardware topology is a three-leg bridge with a neutral connection to the centre-tap of the DC bus. An LQR-based current controller and MAF-based phase detector are implemented. The model is configured for code generation for a Texas Instruments TMS320F28335 Digital Signal Processor (DSP).

Revisiting the Australian code of banking practice: Is self-regulation still relevant for improving consumer protection standards?

The Code of Banking Practice is one of the oldest examples of consumer protection provided through self-regulation in the Australian financial services sector. However, since the Banking Code was first released in 1993, the volume of consumer protection legislation applying to banks has increased exponentially and parts of the Banking Code that once provided new consumer rights have now been largely superseded by legislation. In light of the increasingly complex set of laws and regulations that govern the relationship between banks and their consumer and small business customers it could be argued that the Banking Code has a limited future role. However, an analysis of the Banking Code shows that it adds to the consumer protection standards provided by legislation and can continue to facilitate improvements in the standards of subscribing banks and of other institutions in the financial services sector. Self-regulation and industry codes should continue to be part of the regulatory mix. Any regulatory changes that flow from the recent Financial System Inquiry should also facilitate and support the self-regulation role, but the government should also consider further changes to encourage improvements in industry codes and ensure that the implicit regulatory benefits that are provided, in part, because of the existence of industry codes, are made explicit and made available only to code subscribers.

Grant application: QUT Learning and Teaching scheme 2012 Cracking the Code - A checklist to complement CRAs for first year Justice students.

Widening participation brings with it increasing diversity, increased variation in the level of academic preparedness (Clarke, 2011; Nelson, Clarke, & Kift 2010). Cultural capital coupled with negotiating the academic culture creates an environment based on many assumptions about academic writing and university culture. Variations in staff and student expectations relating to the teaching and learning experience is captured in a range of national and institutional data (AUSSE, CEQ, LEX). Nationally, AUSSE data (2009) indicates that communication, writing, speaking and analytic skills, staff expectations are quite a bit higher than students. The research team noted a recognisable shift in the changing cohort of students and their understanding and engagement with feedback and CRAs, as well as variations in teaching staff and student expectations. The current reality of tutor and student roles is that: - Students self select when/how they access lectures and tutorials. - Shorter tutorial times result in reduced opportunity to develop rapport with students. - CRAs are not always used consistently by staff (different marking styles and levels of feedback). - Marking is not always undertaken by the student’s tutor/lecturer. - Student support services might be recommended to students once a poor grade has been given. Students can perceive this as remedial and a further sense of failure. - CRA sheet has a mark /grade attached to it. Stigma attached to low mark. Hard to focus on the CRA feedback with a poor mark etched next to it. - Limited opportunities for sessionals to access professional development to assist with engaging students and feedback. - FYE resources exist, however academic time is a factor in exploring and embedding these resources. Feedback is another area with differing expectations and understandings. Sadler (2009) contends that students are not equipped to decode the statements properly. For students to be able to apply feedback, they need to understand the meaning of the feedback statement. They also need to identify, the particular aspects of their work that need attention. The proposed Checklist/guide would be one page and submitted with each assessment piece thereby providing an interface to engage students and tutors in managing first year understandings and expectations around CRAs, feedback, and academic practice.

Strategically Pleading Intentional Torts in medical cases

The opportunities and challenges faced by litigants who strategically plead intentional torts are borne out by two recent medical cases. Both arose out of dental treatment. Dean v Phung established some key principles which were clarified in White v Johnston. Before considering those two cases it is worth examining the environment in which such intentional torts claims now exist. Following the Ipp Review of the Law of Negligence, non-uniform legislative changes to the law of negligence were introduced across Australia which have imposed limitations on liability and quantum of damages in cases where a person has been injured through the fault of another. While it seems that, given the limitation of the scope of the review and recommendations to negligently caused damage, the Ipp Review reforms were meant to be limited to injury resulting from negligent acts rather than intentional torts, the extent to which the civil liability legislation applies to intentional torts differs across Australia.

Development of a computer code to predict cooling of die and billet in forging

A hot billet in contact with relatively cold dies undergoes rapid cooling in the forging operation. This may give rise to unfilled cavities, poor surface finish and stalling of the press. A knowledge of billet-die temperatures as a function of time is therefore essential for process design. A computer code using finite difference method is written to estimate such temperature histories and validated by comparing the predicted cooling of an integral die-billet configuration with that obtained experimentally.

A computer code for enclosed natural convection in the boundary layer regime

A computer code is developed for the numerical prediction of natural convection in rectangular two-dimensional cavities at high Rayleigh numbers. The governing equations are retained in the primitive variable form. The numerical method is based on finite differences and an ADI scheme. Convective terms may be approximated with either central or hybrid differencing for greater stability. A non-uniform grid distribution is possible for greater efficiency. The pressure is dealt with via a SIMPLE type algorithm and the use of a fast elliptic solver for the solenoidal velocity correction field significantly reduces computing times. Preliminary results indicate that the code is reasonably accurate, robust and fast compared with existing benchmarks and finite difference based codes, particularly at high Rayleigh numbers. Extension to three-dimensional problems and turbulence studies in similar geometries is readily possible and indicated.

Assessment of code bias variations of BDS triple-frequency signals and their impacts on ambiguity resolution for long baselines

Carrier phase ambiguity resolution over long baselines is challenging in BDS data processing. This is partially due to the variations of the hardware biases in BDS code signals and its dependence on elevation angles. We present an assessment of satellite-induced code bias variations in BDS triple-frequency signals and the ambiguity resolutions procedures involving both geometry-free and geometry-based models. First, since the elevation of a GEO satellite remains unchanged, we propose to model the single-differenced fractional cycle bias with widespread ground stations. Second, the effects of code bias variations induced by GEO, IGSO and MEO satellites on ambiguity resolution of extra-wide-lane, wide-lane and narrow-lane combinations are analyzed. Third, together with the IGSO and MEO code bias variations models, the effects of code bias variations on ambiguity resolution are examined using 30-day data collected over the baselines ranging from 500 to 2600 km in 2014. The results suggest that although the effect of code bias variations on the extra-wide-lane integer solution is almost ignorable due to its long wavelength, the wide-lane integer solutions are rather sensitive to the code bias variations. Wide-lane ambiguity resolution success rates are evidently improved when code bias variations are corrected. However, the improvement of narrow-lane ambiguity resolution is not obvious since it is based on geometry-based model and there is only an indirect impact on the narrow-lane ambiguity solutions.
