Investing In People To Develop The Ideal Culture, Margie H. Jantti

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

While technical skills and professional qualifications will continue to play an important role in the identification and selection of people to join our organisations, the development of life-long learning skills will be the corner-stone of an organisation’s ongoing success and capacity to develop and adapt in a constantly shifting market place. Change is the only constant is the catch phrase of the moment. In a climate of ever-accelerating, and often overwhelming change, the ability of individuals to develop suites of skills and knowledge that promote flexibility, innovation and creativity will be a key determinant of an organisation’s future success or …

A Systemic Approach To Working With Academic Staff: Addressing The Confusion At The Source, Alisa Percy, Jan Skillen

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

The role of the learning adviser in the tertiary context could be argued to be in a period of transformation with the changing culture of modern universities. While in many respects we are still attempting to develop an appropriate and comprehensive definition of our role at the national level, the approach we take is often dependent on our university’s organisation, philosophy and policy. In response to a number of educational and economic factors, in some universities the role of the learning adviser is moving from one that operates in the remedial mode focusing solely on student skills development, to one …

Complementary Pedagogical Strategies For Online Design, Sandra Wills, Albert Ip, Adair Bunnett

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

The First Fleet Convict Database has had a 20 year journey as an exemplar of educational software, published first on mainframe, then microcomputer, and now the web. We describe how the nature of the web environment has changed the nature of this educational package. Pedagogically, databases of primary source data provide students with a learning experience based on the inquiry learning model however, observations of students and teachers in the past 20 years have indicated that database searching is shallow and investigation perfunctory. Before, we could have blamed unwieldy search engines. Now that this obstacle appears to have been removed, …

Key Issues In The Provision Of Correctional Services For Women, Mitchell K. Byrne, Kevin Howells

Faculty of Social Sciences - Papers (Archive)

The time has arrived for a more detailed analysis of the specific needs of female offenders. Even though there is an increasing prevalence, internationally, of women in prison, there is a perception in the literature that governments and correctional systems have failed to deliver reforms and changes in the management of women prisoners. The extent of need identified in the international literature is of relevance to Australia, where the number of female prisoners also appears to be on the increase - in 1983 women comprised 3.9% of the entire prison population, in 1990, 5.4% and in 1998: 6%. Easteal (1992) …

Female Offenders Are Different Form Male Offenders: Anger As An Example, Jennifer Suter, Mitchell K. Byrne

Faculty of Social Sciences - Papers (Archive)

Anger is a common, universally experienced emotion, which occurs on a continuum from mild annoyance to rage or fury (Daffenbacher et al., 1996). Anger is likely to occur when a person believes their personal rights or codes have been violated. Similarly, anger can occur when a person feels powerless or threatened (Horn and Towl, 1997). Anger consists of interrelated, reciprocal components (Novaco, 1975). Environmental circumstances often trigger anger. Physiological symptoms can serve to alert the individual that they are angry, and can help them provide a label to that anger. Cognitions refer to the individual's style of thinking about, or …

Trauma Reactions In The Offender, Mitchell K. Byrne

Faculty of Social Sciences - Papers (Archive)

The psychological sequelae to an incident, objectively defined as 'traumatic', may range from no reaction or mild depression through to dissociative experiences and post-traumatic stress disorder (PTSD). In this paper I intend to survey more severe responses to trauma as experienced by offenders, in particular, violent offenders. While the symptomology overlap, the two key trauma reactions discussed are PTSD and Dissociative Disorders. The importance of dissociation has recently been emphasized by Gershuny and Thayer (1999) who have found that not only is dissociation associated with trauma but that those who do dissociate are more likely to experience higher Ievels of …

Attempted Suicide: Listening To And Learning From Young People, Susan Gair, Peter J. Camilleri

Faculty of Social Sciences - Papers (Archive)

Suicide has become a major international health issue. Australia records one of the highest youth suicide rates in the world and Queensland has one of the highest suicide rates in Australia. This study sought insights into the suicide attempts of young men and women who survived. In-depth interviews were conducted in Townsville, Queensland, with a small group of young men and women aged 16-24 to explore the circumstances leading to the attempted suicide, the help sought and their suggestions for more effective intervention. The findings offer insight into the needs of local at-risk youth and provide suggestions for intervention services …

Thermoregulation By Kangaroos From Mesic And Arid Habitats: Influence Of Temperature On Routes Of Heat Loss In Eastern Grey Kangaroos (Macropus Giganteus) And Red Kangaroos (Macropus Rufus), Terence J. Dawson, Cyntina E. Blaney, Adam J. Munn, Andrew Krockenberger, Shane K. Maloney

Faculty of Science - Papers (Archive)

We examined thermoregulation in red kangaroos (Macropus rufus) from deserts and in eastern grey kangaroos (Macropus giganteus) from mesic forests/woodlands. Desert kangaroos have complex evaporative heat loss mechanisms, but the relative importance of these mechanisms is unclear. Little is known of the abilities of grey kangaroos. Our detailed study of these kangaroos' thermoregulatory responses at air temperatures (T-a) From -5 degrees to 45 degrees C showed that, while some differences occur, their abilities are fundamentally similar. Both species show the basic marsupial characteristics of relatively low basal metabolism and body temperature (T-b). Within the thermoneutral zone, T-b was 36.3 degrees …

Enhanced Tumor Growth In Uv-Irradiated Skin Is Associated With An Influx Of Inflammatory Cells Into The Epidermis, Ronald Sluyter, Gary M. Halliday

Faculty of Science - Papers (Archive)

UV radiation causes a number of cellular changes within the skin which play a role in tumor outgrowth, including immunosuppression and production of growth-enhancing cytokines, Both of these enable tumors to grow but their relative importance in carcinogenesis is poorly defined. In this study, C3H/HeN mice were exposed to a single inflammatory dose of 410 mJ/cm(2) UVB radiation (plus 100 mJ/cm2 UVA radiation) followed by the inoculation of a regressor squamous cell carcinoma into or the painting of oxazolone onto the treated skin. Tumors transplanted 2 or 3 but not 4 days after irradiation had a significantly higher growth rate …

Single Nucleotide Primer Extension (Snupe) Analysis Of The G6pd Gene In Somatic Cells And Oocytes Of A Kangaroo (Macropus Robustus), Debbie Watson, Anita S. Jacombs, David A. Loebel, Edward S. Robinson, Peter G. Johnston

Faculty of Science, Medicine and Health - Papers: part A

cDNA sequence analysis of the X-linked glucose-6-phosphate dehydrogenase (G6PD) gene has shown a base difference between two subspecies of the kangaroo, Macropus robustus robustus (wallaroo) and M. r. erubescens (euro). A thymine residue in the wallaroo at position 358 in exon 5 has been replaced by a cytosine residue in the euro, which accounts for the previously reported electrophoretic difference between the two subspecies. This base difference allowed use of the Single Nucleotide Primer Extension (SNuPE) technique to study allele-specific expression of G6PD at the transcriptional level. We began by examining G6PD expression in somatic cells and observed complete paternal …

Vertical Profiles Of Nitrous Oxide Isotopomer Fractionation Measured In The Stratosphere, D W. T Griffith, Geoffrey Toon, Bhaswar Sen, Jean-Francois Blavier, Robert A. Toth

Faculty of Science, Medicine and Health - Papers: part A

We have measured the vertical profiles of several isotopomers of nitrous oxide, N₂O, in the stratosphere by balloon-borne infrared remote sensing between 15 and 35 km. In particular we distinguish the individual profiles and relative enrichments of the positional isotopomers ¹⁵N¹⁴N¹⁶O and ¹⁴N¹⁵N¹⁶O for the first time. We find a distinct and reproducible relative enrichment of the isotopomers which is in general agreement with measured photolysis rates in the laboratory and theoretical predictions. The results confirm photolysis as the dominant stratospheric loss process for N₂O and …

Role Of Phosphoglucomutase Of Bordetella Bronchiseptica In Lipopolysaccharide Biosynthesis And Virulence, Nicholas P. West, Heidrun Jungnitz, John Fitter, Jason D. Mcarthur, Carlos Guzman, Mark J. Walker

Faculty of Science, Medicine and Health - Papers: part A

The phosphoglucomutase (PGM)-encoding gene of Bordetella bronchiseptica is required for lipopolysaccharide (LPS) biosynthesis. An insertion mutant of the wild-type B. bronchiseptica strain BB7865 which disrupted LPS biosynthesis was created and characterized (BB7865pgm). Genetic analysis of the mutated gene showed it shares high identity with PGM genes of various bacterial species and forms part of an operon which also encompasses the gene encoding phosphoglucose isomerase. Functional assays for PGM revealed that enzyme activity is expressed in bothbvg-positive and bvg-negative strains ofB. bronchiseptica and is substantially reduced in BB7865pgm. Complementation of the mutated PGM …

Conference Report: Dietary Guidelines For A New Millennium, Peter R.C Howe, Paul Nestel

Faculty of Science, Medicine and Health - Papers: part A

The US dietary guidelines are being updated, new dietary guidelines for older Australians were released last year, and Australia and New Zealand are jointly reviewing recommendations for nutrient intakes. Who needs them? Are they merely bureaucratic exercises or should we be taking them seriously? If so, how should they be managed for maximum benefit?

The Carletonville-Mothusimpilo Project: Limiting Transmission Of Hiv Through Community-Based Interventions, Brian G. Williams, Catherine L. Mac Phail, Catherine Campbell, D Taljaard, Eleanor Gouws, S Moema, Z Mzaidume, B Rasego

Faculty of Social Sciences - Papers (Archive)

For all of the last century, the economy of South Africa, and so also of its neighbouring countries, has depended on migrant labour from rural areas. This is particularly so for the mining industry, especially hard-rock mining, and this has led to a system of 'oscillating' migration whereby men from rural areas come to live and work on the mines, without their wives or families, but return home regularly. This pattern of oscillating migration is an important determinant of health and, especially at the start of the epidemic, contributed to the spread of HIV in the region. In this paper …

Visually Directed Walking To Briefly Glimpsed Targets Is Not Biased Toward Fixation Location, John W. Philbeck

Faculty of Social Sciences - Papers (Archive)

When observers indicate the magnitude of a previously viewed spatial extent by walking without vision to each endpoint, there is little evidence of the perceptual collapse in depth associated with some other methods (eg visual matching). One explanation is that both walking and matching are perceptually mediated, but that the perceived layout is task-dependent. In this view, perceived depth beyond 2 - 3 m is typically distorted by an equidistance effect, whereby the egocentric distances of nonfixated portions of the depth interval are perceptually pulled toward the fixated point. Action-based responses, however, recruit processes that enhance perceptual accuracy as the …

Online Support For Preservice Mathematics Teachers In Schools, Anthony Herrington, Janice Herrington, Arshad Omari

Faculty of Social Sciences - Papers (Archive)

This paper describes the development of a web-based resource designed to support preservice mathematics teachers on school practice. The development of the site resulted in part from a needs analysis conducted with a focus group of students. The purpose of the focus group discussion was to gain from the students their ideas about the type of support that would be most helpful to them as they prepare to teach mathematics lessons, and how the university might be able to assist in these sometimes prolonged periods in school where they are without their traditional support structures. As a result of these …

Preservice Teachers' Understanding And Representation Of Equality Of Fractions In A Javabars Environment, Mohan Chinnappan

Faculty of Social Sciences - Papers (Archive)

In recent years, considerable research effort has been invested in identifying the nature of the knowledge that drives mathematics teachers’ actions in the classroom. While this investigation has generated a useful body of information, there has been little information about changes in the character of this knowledge when teaching involves the use of technology. In this paper, I address this issue by examining a group of preservice primary mathematics teachers’ understanding of fractions. The participants were required to order fractions within software called JavaBars. The results suggest that, while the preservice teachers had built up robust knowledge about fractions, they …

Severe Maternal Psychopathology And Infant-Mother Attachment, A E. Hipwell, Frits Goossens, Edward Melhuish, R Kumar

Faculty of Social Sciences - Papers (Archive)

Eighty-two mother-infant dyads, comprising women with psychiatric disorder and individually matched controls, were followed up over the children's 1st year of life. The mothers with mental illness consisted of two subgroups: first, 25 severely mentally ill mothers who had been admitted to a psychiatric unit with their infants; and second, 16 mothers from a community sample meeting research diagnostic criteria for unipolar, nonpsychotic depression. With the exception of six dyads in the in-patient group, observations were made of the mother-infant interaction and the quality of the infant-mother attachment relationship at 12 months. The nature and course of the mothers' illness …

The C*-Algebras Of Row-Finite Graphs, Teresa Bates, David Pask, Iain Raeburn, Wojciech Szymanski

Faculty of Engineering and Information Sciences - Papers: Part A

We prove versions of the fundamental theorems about Cuntz-Krieger algebras for the C*-algebras of row-finite graphs: directed graphs in which each vertex emits at most finitely many edges. Special cases of these results have previously been obtained using various powerful machines; our main point is that direct methods yield sharper results more easily.

Non-Gravitational Heating In The Hierarchical Formation Of X-Ray Clusters, K K S Wu, A C. Fabian, Paul E J Nulsen

Faculty of Engineering and Information Sciences - Papers: Part A

The strong deviation in the properties of X-ray clusters from simple scaling laws highlights the importance of non-gravitational heating and cooling processes in the evolution of protocluster gas. We investigate this from two directions: by finding the amount of ‘excess energy’ required in intracluster gas in order to reproduce the observed X-ray cluster properties, and by studying the excess energies obtained from supernovae in a semi-analytic model of galaxy formation. Using the insights obtained from the model, we then critically discuss possible ways of achieving the high excess specific energies required in clusters. These include heating by supernovae and active …

The C*-Algebras Of Infinite Graphs, Neal J. Fowler, Marcelo Laca, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

We associate C*-algebras to infinite directed graphs that are not necessarily locally finite. By realizing these algebras as Cuntz-Krieger algebras in the sense of Exel and Laca, we are able to give criteria for their uniqueness and simplicity, generalizing results of Kumjian, Pask, Raeburn, and Renault for locally finite directed graphs.

Integer-Modulated Filter Banks Providing Perfect Reconstruction, Alfred Mertins, Tanja Karp, Jorg Kliewer

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we extend the perfect reconstruction conditions known for cosine modulation to other, more general modulation schemes. The modified PR conditions provide additional degrees of freedom which can be utilized to design integer-modulated filter banks. Techniques for the design of prototypes and modulation sequences are presented.

Network Reconfiguration For Enhancement Of Voltage Stability In Distribution Networks, Kashem M. Muttaqi, Velappa Ganapathy, G G. Jasmon

Faculty of Engineering and Information Sciences - Papers: Part A

Network reconfiguration is performed by altering the topological structure of distribution feeders. By reconfiguring the network, voltage stability can be maximised for a particular set of loads in distribution systems. A new algorithm is formulated for enhancement of voltage stability by network reconfiguration. Initially, a certain number of switching combinations is generated using the combination of tie and its two neighbouring switches, and the best combination of switches for maximising the voltage stability in the network among them is determined. Then the search is extended by considering the branches next to the open-branches of the best configuration one by one …

Naturality And Induced Representations, Siegfried Echterhoff, S Kaliszewski, John Quigg, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

We show that induction of covariant representations for C^*-dynamical systems is natural in the sense that it gives a natural transformation between certain crossed-product functors. This involves setting up suitable categories of C^*-algebras and dynamical systems, and extending the usual constructions of crossed products to define the appropriate functors. From this point of view, Green's Imprimitivity Theorem identifies the functors for which induction is a natural equivalence. Various special cases of these results have previously been obtained on an ad hoc basis.

The Method Of Generalised Conditional Symmetries And Its Various Implementations, Joanna Goard

Faculty of Engineering and Information Sciences - Papers: Part A

We relate Kaptsov's method of B-determining equations for finding invariant solutions of PDEs to the nonclassical method and to the method of generalised conditional symmetries. An extension of Kaptsov's method is then used to find new solutions of degenerate diffusion equations.
