Web-Based Surveys And Assessment, Parviz Doulai, Ray Stace

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

This paper describes methods of on-line assessment and students’ survey, which utilize the Web interfaces and use them in conjunction with the Internet. To find the most appropriate alternative methods of students’ assessment and survey a variety of commercial and public domain tools was used to implement the following two basic tasks: 1. ‘Student Suggestion Box’ where students evaluate the subject and make comments and suggestions on the subject and its assessment; and 2. a partially AutoMark short assessment task, containing two paragraph questions and three multiple choice questions, that offers final marks to the instructor/students and provides prompt feedback …

Applied Epidemiology - A Full-Subject Self-Directed Computer-Based Problem-Solving Learning Experience, I. A. Kreis, Adam Orvad, Dhammika Ruberu, Ray Stace

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

A major difficulty of teaching public health to students in a Masters Program is conveying the need for taking a strategic approach to situations. Tackling real-life public health issues is rather complex. There will generally be a number of avenues of investigation and it is necessary to be wary of the short and long-term consequences of actions. Also time and money need to be managed effectively. As one approach to the education of students about these issues, a computer-based package has been developed which simulates the investigation of a real public health problem. This simulation enables students to encounter such …

In the design process the multi degree of freedom structures are considered so that it makes improvement to the available design procedures so far, where usually only single mode model is considered.

Structural And Superconducting Properties Of R1 – Xcaxba2cu3o7 – Delta With 0.50 >= X >= 0.00, A. Sedky, A. Gupta, V. P. Awana, A. V. Narlikar

Faculty of Engineering - Papers (Archive)

We report here a consolidated study of structural and superconducting properties of Ca substituted R1-xCaxBa2Cu3O7-δ system, with R=Er, Y, Sm, and Nd, and for 0.50>~x>~0.00. Interestingly, with increasing x, Er/Y samples show a behavior significantly different from Sm/Nd. In particular (1) orthorhombic distortion of R:123 lattice is found to be little affected for Er/Y samples with increasing x in comparison to Sm/Nd samples, (2) although Ca substitution leads to oxygen depletion for all the four sets of samples, the average Cu valence is, in general, found to remain invariant with x, (3) ρ(T) is found to show an …

The ‘Graduate Woman’ Phenomenon: Changing Constructions Of The Family In Singapore, Lenore T. Lyons-Lee

Faculty of Arts - Papers (Archive)

The central role of the family in state discourses of social change has been well documented in the case of Singapore. Within this discourse, the state has sought to strengthen the family as a key social structure and, while relegating the family to the realm of the ‘private”, has sought simultaneously to construct its own vision of family life. Women occupy a central role in this discourse of ‘state fatherhood” - they are both the mothers of the nation and the imparters of core cultural and national values. In recent years, in an attempt to address a perceived rejection of …

"...A Small Fish In A Small Pond..." The Reverend W.B. Clarke (1798-1878): 200 Years On, Michael K. Organ

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

The Reverend W.B. Clarke remains something of an enigma in the annals of Australian science, despite the publication of numerous books and articles on his life and times. The author argues that this is mainly due to the deficiencies of previous researchers in addressing the full gamut of that Reverend gentleman’s work. Though the basic details of Clarke’s life are clearly known, numerous significant gaps exist in the surviving archive. For example, his personal collection of rocks, fossils, geological maps and library was destroyed in the Garden Palace fire of 1882; his large corpus of work which appeared in Australian …

Elementary Electronic Excitation In Three-Dimensional Electron Gases Under Free-Electron Laser Radiations, W. Xu

Faculty of Engineering - Papers (Archive)

I present a detailed theoretical study of the collective excitation associated with plasmon modes in threedimensional electron gases 3DEG’s, subject to free-electron laser FEL radiations. Using the exact solution of the time-dependent Schro¨dinger equation in which the effect of the electromagnetic e.m. radiation field is included in the Coulomb gauge, I have derived the Green’s function, the density of states DOS, and the density-density correlation function for free electrons in (K,t) and K, representation. With these results, the influence of the FEL radiations on plasmon spectrum in a 3DEG has been studied by employing the randomphase approximation. It has been …

Nonlinear Single-Electron Tunneling Through Individually Coated Colloid Particles At Room Temperature , S. T. Yau, P. Mulvaney, W. Xu, Geoffrey M. Spinks

Faculty of Engineering - Papers (Archive)

Single-electron tunneling (SET) has been observed with nanometer coated colloid gold particles at room temperature. We have made the smallest (3-nm) thiol- and silicon dioxide (SiO2)-coated gold particles, from which we obtained SET signals using a scanning tunneling microscope (STM)images reveal individual particles supported by an atomically flat metal surface. The STM tip is used to obtain SET signals from the individual particles, whose shapes have been characterized. The current-voltage curves of the particles exhibit well-defined Coulomb staircases that resemble those obtained at 4.2 K, indicating a strong Coulomb repulsive interaction at room temperature. The clear Coulomb staircases are due …

On Circulant Weighing Matrices, K. T . Arasu, Jennifer Seberry

Faculty of Informatics - Papers (Archive)

Algebraic techniques are employed to obtain necessary conditions for the existence of certain circulant weighing matrices. As an application we rule out the existence of many circulant weighing matrices. We study orders n = s2 + s + 1, for 10 less than or equal to s less than or equal to 25. These orders correspond to the number of points in a projective plane of order s.

Group Divisible Designs, Gbrsds And Generalized Weighing Matrices, D. G. Sarvate, Jennifer Seberry

Faculty of Informatics - Papers (Archive)

We give new constructions for regular group divisible designs, pairwise balanced designs, generalized Bhaskar Rao supplementary difference sets and generalized weighing matrices. In particular if p is a prime power and q divides p – 1 we show the following exist:

(i) GDD(2(p2 +p+ 1), 2(p2 +p+ 1), rp2, 2p2, λ1 = p2λ, λ2 = (p2 —p)r, m = p2 + p+ 1, n = 2), r = 1,2;

(ii) GDD(q(p+ 1), q(p+ 1), p(q – 1), p(q –1), λ1 = (q – 1)(q – 2), λ2 = (p– 1)(q – 1)2/q, m = q, n = p+1);

(iii) PBD(21, …

Pass The Plate Around Again: A Study Of Budgeting In A Local Church, H. J. Irvine

Faculty of Commerce - Papers (Archive)

How does a religious organization, with a spiritual agenda, reconcile the inevitable tension between its spiritual aims and the necessity of providing funds in order to fulfill those aims? What part does accounting play in the working out of this tension? Are there implications, because of spiritual considerations, for the acceptance of accounting as a legitimate management tool? How does a religious organization protect its belief system from the potential corruption accounting might bring? These are all issues that have been raised in the study of churches and other religious organizations from the point of view of a sacred/ secular …

'Osterreich In Australien': Ferdinand Von Hochstetter And The Austrian Novara Scientific Expedition 1858-9, Michael K. Organ

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

During 1858 and 1859 the Austrian geologist Ferdinand Hochstetter visited Australia in connection with the Novara round-the-world scientific expedition. While much of significance was published as a result of Hochstetter's researches in New Zealand during 1859, the same cannot be said for his time in New South Wales and Victoria. With the aid of recently uncovered manuscript geological notebooks and contemporary material originally issued in German-language scientific journals, a preliminary assessment can be made of his visit to the Australian colonies. Aspects of the reception Hochstetter and his fellow Novara scientists received, and in turn his views on the state …

Nonlinear Optical Absorption And Lo-Phonon Emission In Steady-State Terahertz-Driven Three-Dimensional Electron Gases, W. Xu

Faculty of Engineering - Papers (Archive)

We present a detailed theoretical study on nonlinear transport and optical properties in three-dimensional electron gases 3DEG's subjected to intense terahertz THz electromagnetic radiation fields. The steady-state electronic transition rate induced by electron-photon-phonon interactions in a 3DEG system has been derived by using an approach from which the effects of multiphoton processes can be easily included. By solving the momentum- and energy-balance equations based on a steady-state Boltzmann equation, where electron interactions with LO phonons are taken into account, we have investigated the dependence of electron temperature, relaxation time, mobility, multiphoton absorption and emission, and photon-assisted LO-phonon emission on the …

Shear Behaviour Of Railway Ballast Based On Large Scale Triaxial Testing, Buddhima Indraratna, D. Ionescu, H. D. Christie

Faculty of Engineering - Papers (Archive)

Quarried rock fragments (ballast) constitute one of the most commonly used construction matierals in railway engineering. Ballast is subjected to high stress levels as well as being always exposed to environmental changes. Unsatisfactory performance of railway tracks is often associated with the loss of cross level, track profile and track alignment.
