Introduction and Aims. With the headline 'Ecstasy Over The Counter' in a popular daily newspaper, the debate on drug policy officially entered the arena of the 2003 New South Wales (Australia) State Election. The debate resurfaced in the lead-up to the 2004 Australian Federal Election. This paper analyses the pre-election coverage of drug policy issues in four Australian newspapers. Design and Methods. Four high-circulation daily newspapers were monitored for a one-month period prior to both elections and analysed for their coverage of drug policy, particularly with respect to the policy of the Greens. Results. The newspapers took different perspectives on …

Numerical Analysis Of Roll Deflection For Sendzimir Mill, H L. Yu, X H. Liu, G T. Lee, X W. Li, H D. Park

Faculty of Engineering and Information Sciences - Papers: Part A

The present work introduces a new type of numerical analyzing method: the contact element method with two relative coordinates (CEM). The main characteristic of the procedure is elements meshing on the basis of the contact length between objects and that each element has two relative coordinates. The ordinary expression of this procedure is DX[CXY(i)]=D Y[CYX(i)]. Through this method, the CEM function of the 20-high Sendzimir mill and the deflection function expression of every roll are obtained. A computational software SM4SM for the Sendzimir mill has been developed, by which the deflection condition of rolls S, O, I, and A can …

Evolution Analysis Of Low-Cost Iterative Equalization In Coded Linear Systems With Cyclic Prefixes, Xiaojun Yuan, Qinghua Guo, Xiaodong Wang, Li Ping

Faculty of Engineering and Information Sciences - Papers: Part A

This paper is concerned with the low-cost iterative equalization/detection principles for coded linear systems with cyclic prefixes. Turbo frequency-domain-equalization (FDE) is applied to systems that may contain the joint effect of multiple-access interference (MAI), cross-antenna interference (CAI) and inter-symbol interference (ISI). We develop an SNK-variance evolution technique for the performance evaluation of the proposed systems. Numerical results in various channel environments demonstrate excellent agreement between the predicted and simulated system performance. © 2008 IEEE.

Performance Analysis Of Multi-Ary Systems With Iterative Linear Minimum-Mean-Square-Error Detection, Li Ping, Jun Tong, Xiaojun Yuan, Qinghua Guo

Faculty of Engineering and Information Sciences - Papers: Part A

This paper is concerned with coded multi-ary systems over linear channels. Based on a semi-analytical evolution technique, the impact of signaling schemes on the performance of low-cost iterative linear minimum-mean-square-error (LMMSE) detection is studied. It is shown that superposition coded modulation (SCM) maximizes the output signal-to-noise ratio (SNR) of LMMSE detectors. Consequently, SCM may potentially outperform other conventional signaling schemes when LMMSE detectors are used. Numerical examples are provided to verify the theoretical analysis. © 2008 IEEE.

We've Thrown Away The Pens, But Are They Learning? Using Blogs In Higher Education, Katrina Strampel, Ron Oliver

Research outputs pre 2011

In today’s university classrooms, “the time of restricting students products and learning opportunities to ink on paper are past” (Siegle, 2007). Blogs are only one of many computer-mediated technologies starting to dominate blended and wholly online courses. Most people assume that using these technologies, because it is what the students want, will translate into increased learning opportunities. As the literature continuously asserts, however, learning, and especially reflection, does not just happen (Boud, Keogh, & Walker, 1985). It seems imperative, therefore, that extra measures are taken when any technology is being implemented in a university classroom to ensure high levels of …

Social Choice And Information: A Note On The Calculus Of Mappings From Utility Spaces, Alex Coram

Economics Department Working Paper Series

Social choice is studied in this paper as a mapping from information on utilities over states of the world to an ordering of those states of the world. The idea of using this type of information originates in the work of Sen and Roberts. This paper differs in that it uses theorems from analysis to derive its results in a straightforward manner. It also gives information on the way in which all states of the world, on any path through the set of states of the world, must be ordered.

An Analysis Of The Financial Services Regulations Of Australia, Shyam S. Bhati

Faculty of Commerce - Papers (Archive)

The purpose of this paper is to critically analyse various aspects of Australian Financial Services Regulation in terms of Llewellyn’s Theory of Financial Services Regulation and offer suggestions for the improvement of FSR based on the analysis. A discussion based approach is used to conduct this analysis. It is observed that the FSR Act, 2001 of Australia does not cover credit products thereby leaving an important segment of the market outside the purview of the Act. The policies developed by Australian Securities and Investment Commission (ASIC) on FSR Act relies on Industry self regulation as mechanism of creating trust and …

Empirical Analysis Of The Uae Stock Market Volatility, Sami Khedhiri, Naeem Muhammad

Faculty of Commerce - Papers (Archive)

Financial market volatility of developed economies have been studied extensively since the 1987 stock market crash as well as the volatility of the East Asian stock markets after the East Asian financial crisis. However the volatility characteristics of the financial markets in the Middle East are far from being thoroughly analysed despite their tremendous growth in recent years. The purpose of this paper is twofold. First, we investigate the volatility characteristics of the UAE stock markets measured by fat tail, volatility clustering, and leverage effects, in order to explore a parsimonious model for the UAE stock market and predict its …

Performance Analysis Of Ofdm-Idma Systems With Peak-Power Limitation, Jun Tong, Qinghua Guo, Li Ping

Faculty of Engineering and Information Sciences - Papers: Part A

This paper is concerned with orthogonal frequency-division multiplexing interleave-division multiple-access (OFDM-IDMA) systems over frequency-selective fading channels. Deliberate clipping is applied to reduce the peak-to-average power ratio (PAPR) of each user's transmitted signal. An iterative multiuser detection (MUD) technique is developed to recover the performance loss due to clipping. A semi-analytical signal-to- noise ratio (SNR) evolution technique is proposed, which can provide quick and accurate prediction of the iterative MUD performance. Numerical results show that the performance of OFDM-IDMA is not sensitive to the frequency selectivity of channels, and OFDM-IDMA is more power-efficient than other alternative multi-carrier transmission techniques. © 2008 …

An Analysis Of The Criteria For Evaluating Adequate Theories Of Computation, Nir Fresco

Faculty of Engineering and Information Sciences - Papers: Part A

This paper deals with the question: What are the criteria that an adequate theory of computation has to meet? (1) Smith's answer: it has to meet the empirical criterion (i.e. doing justice to computational practice), the conceptual criterion (i.e. explaining all the underlying concepts) and the cognitive criterion (i.e. providing solid grounds for computationalism). (2) Piccinini's answer: it has to meet the objectivity criterion (i.e. identifying computation as a matter of fact), the explanation criterion (i.e. explaining the computer's behaviour), the right things compute criterion, the miscomputation criterion (i.e. accounting for malfunctions), the taxonomy criterion (i.e. distinguishing between different classes …

Regularized Discriminative Direction For Shape Difference Analysis, Luping Zhou, Richard Hartley, Lei Wang, Paulette Lieby, Nick Barnes

Faculty of Engineering and Information Sciences - Papers: Part A

The "discriminative direction" has been proven useful to re- veal the subtle difference between two anatomical shape classes. When a shape moves along this direction, its deformation will best manifest the class difference detected by a kernel classifier. However, we observe that such a direction cannot maintain a shape's "anatomical" correctness, in- troducing spurious difference. To overcome this drawback, we develop a regularized discriminative direction by requiring a shape to conform to its population distribution when it deforms along the discriminative direction. Instead of iterative optimization, an analytic solution is pro- vided to directly work out this direction. Experimental study …

High Resolution Analysis Of Uranium And Thorium Concentration As Well As U-Series Isotope Distributions In A Neanderthal Tooth From Payre (Ardeche, France) Using Laser Ablation Icp-Ms, R. Grun, Maxime Aubert, Renaud C. Joannes-Boyau, M-H Moncel

Faculty of Science - Papers (Archive)

We have mapped U (238U) and Th (232Th) elemental concentrations as well as U-series isotope distributions in a Neanderthal tooth from the Middle Palaeolithic site of Payre using laser ablation ICP-MS. The U-concentrations in an enamel section varied between 1 and 1500 ppb. The U-concentration maps show that U-migration through the external enamel surface is minute, the bulk of the uranium having migrated internally via the dentine into the enamel. The uranium migration and uptake is critically dependent on the mineralogical structure of the enamel. Increased U-concentrations are observed along lineaments, some of which are associated with cracks, and others …

Initial Severity And Antidepressant Benefits: A Meta-Analysis Of Data Submitted To The Food And Drug Administration, Irving Kirsch, Brett J. Deacon, Tania B. Huedo-Medina, Alan Scoboria, Thomas J. Moore, Blair T. Johnson

Faculty of Social Sciences - Papers (Archive)

Background: Meta-analyses of antidepressant medications have reported only modest benefits over placebo treatment, and when unpublished trial data are included, the benefit falls below accepted criteria for clinical significance. Yet, the efficacy of the antidepressants may also depend on the severity of initial depression scores. The purpose of this analysis is to establish the relation of baseline severity and antidepressant efficacy using a relevant dataset of published and unpublished clinical trials. Methods and Findings: We obtained data on all clinical trials submitted to the US Food and Drug Administration (FDA) for the licensing of the four new-generation antidepressants for which …
