Misattribution Of Sensory Input Reflected In Dysfunctional Target: Non-Target Erps In Schizophrenia, K. Brown, E. Gordon, L. Williams, H. Bahramali, A. Harris, J. Gray, C. J. Gonsalvez, R. Meares Nov 2000

Misattribution Of Sensory Input Reflected In Dysfunctional Target: Non-Target Erps In Schizophrenia, K. Brown, E. Gordon, L. Williams, H. Bahramali, A. Harris, J. Gray, C. J. Gonsalvez, R. Meares

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background. While numerous studies have found disturbances in the Event-Related Potentials (ERPs) of patients with schizophrenia linked to task relevant target stimuli (most notably a reduction in P300 amplitude), few have examined ERPs to task irrelevant non-targets. We hypothesize, from current models of dysfunction in information processing in schizophrenia, that there will be less difference between ERPs to targets and non-targets in patients with schizophrenia than in controls.

Methods. EEGs were recorded for 40 subjects with schizophrenia and 40 age and sex matched controls during an auditory oddball reaction time task. ERPs to the targets and non-targets immediately preceding the ...


Performance Measures, Benchmarking And Value, Felicity Mcgregor Oct 2000

Performance Measures, Benchmarking And Value, Felicity Mcgregor

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

[Extract] The announcement of the establishment of a Quality Audit Agency to evaluate the performance of universities, signalled an inevitable expansion of the incipient culture of measurement and evaluation in Australian universities. Those who consider that quality, and its associated tenets of measurement and evaluation are of dubious value, will be constrained to demonstrate goal achievement through whichever mechanisms are deemed appropriate by the Agency. Otherwise, they may face an uncertain funding future. Although the details of the audit process are not yet clear, there will be a single national body which will be responsible for overseeing independent external quality ...


Accountability, Democracy And The World Economic Forum, Jane Andrew Sep 2000

Accountability, Democracy And The World Economic Forum, Jane Andrew

Faculty of Commerce - Papers (Archive)

Concerns about the state of the global environment has provided the catalyst for significant participation in 'anti-globalisation' protests. These concerns have led many to protest the general lack of social and environmental accountability displayed by multinational companies and elected government officials. This paper considers these issues within the context of a growing protest movement.


Improving Teaching And Learning Through Formative Evaluation: Using A Customised Online Tool To Collect Student Feedback, Robert M. Corderoy, Ray Stace, Sandra Wills, A. Ip Sep 2000

Improving Teaching And Learning Through Formative Evaluation: Using A Customised Online Tool To Collect Student Feedback, Robert M. Corderoy, Ray Stace, Sandra Wills, A. Ip

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

Good teachers spend time reflecting on their teaching practice. What is working, what isn't - and more importantly, why is or isn’t it? Such reflection is an essential component of maintaining and improving both teaching practice and the learning outcomes for students. Changes in current teaching practice towards more flexible teaching and learning environments and especially towards more student-centred online environments make this an even more important process. To answer this kind of question requires data which reflect the student's viewpoint on the teaching process and the time to collect and analyse it. As the subject itself is ...


The Corporate Connection: Financial Reporting In A Large Religious/Charitable Organization In Australia, H. J. Irvine Jul 2000

The Corporate Connection: Financial Reporting In A Large Religious/Charitable Organization In Australia, H. J. Irvine

Faculty of Commerce - Papers (Archive)

Nonprofit organizations operate in an increasingly corporatised, competitive environment. More and more, as institutions with charitable agenda, they need to promote an image that will enhance their ability to attract the funding they require in order to continue their operations. Competition for donations is becoming more intense and society is increasing its expectations about the level of accountability desirable from such organizations. One means by which nonprofit organizations can address this issue of accountability, and present themselves to the public as financially sound and worthy of receiving donations, is through their annual financial statements. As accounting practices have changed over ...

The Politics Of Sociotechnical Intervention: An Interactionist View, Karin Garrety, R Badham Mar 2000

The Politics Of Sociotechnical Intervention: An Interactionist View, Karin Garrety, R Badham

Faculty of Commerce - Papers (Archive)

In this article, we apply concepts from symbolic interactionism - a well-established tradition of interpretivist sociology - to investigate the social and political processes involved in a sociotechnical intervention. The intervention was designed to elicit operator involvement in an experimental trial of an advanced manufacturing system at an industrial site in Australia. The interactionist concepts of social worlds, boundary objects and trajectories are used to explore the interrelationships among the theoretical, practical and contextual elements of intervention. We believe that these concepts are flexible intellectual resources that can extend and enrich our understanding of the politics involved in the shaping of work ...


A State Of Ambivalence: Feminism And A Singaporean Women’S Organisation, Lenore T. Lyons Mar 2000

A State Of Ambivalence: Feminism And A Singaporean Women’S Organisation, Lenore T. Lyons

Faculty of Arts - Papers (Archive)

There has been some interest in recent years in identifying the features or characteristics of an ‘Asian’ or ‘Third-World’ feminism (Moraga and Anzaldua 1983; Jayawardena 1986; Grewal et al. 1988; Mohanty 1991; Basu 1995; Alexander and Mohanty 1997). Part of this concern has focused on a costs-benefits analysis of Asian women ‘coming out’ as feminists in overtly hostile political climates. For many women embracing the identity ‘feminist’ continues to be a difficult process. Caught within multiple and shifting discourses that serve to inscribe place, allegiance and behaviour, being a feminist is not only an expression of individual political belief, but ...


A View On The Process Of Accounting Standard Setting In The People’S Republic Of China, Y. Zhang, J. Andrew, H. W. Collier Jan 2000

A View On The Process Of Accounting Standard Setting In The People’S Republic Of China, Y. Zhang, J. Andrew, H. W. Collier

Faculty of Commerce - Papers (Archive)

This paper is a discussion of how the People’s Republic of China is attempting to revise accounting standards. Historically, China’s accounting standards were dominated by ‘management’ accounting and compliance and achievement of goals and objectives established by central planning authority. As China seeks Foreign Direct Investment in formerly State Owned Enterprises, competitive pressures demand a change of emphasis in financial reporting. Much of the Western world is adapting IFRS for financial reporting. IFRS seems to privilege western dialogue in the adoption and acceptance of standards if PRC wishes to access the world wide capital markets. Consistency and comparability ...


Clusterin Is A Secreted Mammalian Chaperone, M. R. Wilson, S. B. Easterbrook-Smith Jan 2000

Clusterin Is A Secreted Mammalian Chaperone, M. R. Wilson, S. B. Easterbrook-Smith

Faculty of Science - Papers (Archive)

[Extract] By any criteria, clusterin is an interesting protein. It was first described in 1983 as a secreted glycoprotein in ram rete testis fluid that enhanced aggregation (“clustering”) of a variety of cells in vitro 1. Many homologues in other species were subsequently discovered. Typically, each “discovery” of clusterin in a different species or by a different research group led to it being assigned another name. By the early 1990s clusterin was known under many aliases 2, some of which persist in the literature. However, the inaugural international workshop on clusterin (Cambridge, 1992) agreed to the name clusterin, in deference ...


Contribution To The Theory Of Scarpland Development From Observations In Central Queensland, Australia, R. W. Young, R. A. Wray Jan 2000

Contribution To The Theory Of Scarpland Development From Observations In Central Queensland, Australia, R. W. Young, R. A. Wray

Faculty of Science - Papers (Archive)

Theories of scarpland geomorphology developed over the past century have been characterised by divergent conceptual frameworks and have been hindered by language barriers. Here, we review the main theories and assess them with reference to field evidence from central Queensland, Australia.


Thyroid Hormones And Their Effects: A New Perspective, A. J. Hulbert Jan 2000

Thyroid Hormones And Their Effects: A New Perspective, A. J. Hulbert

Faculty of Science - Papers (Archive)

The thyroid hormones are very hydrophobic and those that exhibit biological activity are 3',5',3,5-ltetraiodothyronine (T4), 3',5,3-l-triiodothyronine (T3), 3',5',3-l-triiodothyronine (rT3) and 3,5,-ldiiodothyronine (3,5-T2). At physiological pH, dissociation of the phenolic -OH group of these iodothyronines is an important determinant of their physical chemistry that impacts on their biological effects. When non-ionized these iodothyronines are strongly amphipathic. It is proposed that iodothyronines are normal constituents of biological membranes in vertebrates. In plasma of adult vertebrates, unbound T4 and T3 are regulated in the picomolar range whilst protein-bound T4 and T3 are maintained ...


Desiccation Tolerance Of Three Moss Species From Continental Antarctica, Sharon A. Robinson, J. Wasley, M. Popp, C. E. Lovelock Jan 2000

Desiccation Tolerance Of Three Moss Species From Continental Antarctica, Sharon A. Robinson, J. Wasley, M. Popp, C. E. Lovelock

Faculty of Science - Papers (Archive)

Tolerance of desiccation was examined in three species of moss, Grimmia antarctici Card., Ceratodon purpureus (Hedw.) Brid. and Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer et Scherb. collected from two sites of contrasting water availability in the Windmill Islands, continental Antarctica. Physiological tolerance to desiccation was measured using chlorophyll fluorescence in plugs of moss during natural drying in the laboratory. Differences in relative water contents, rates of drying and the response of photosynthesis to desiccation were observed among the three species and between sites. Of the three species studied, G. antarctici showed the lowest capacity to sustain photosynthetic processes during desiccation, B ...


Tracing Beach Sand Provenance And Transport Using Foraminifera: Preliminary Examples From Northwest Europe And Southeast Australia, S. K. Haslett, Edward A. Bryant, R. H. Curr Jan 2000

Tracing Beach Sand Provenance And Transport Using Foraminifera: Preliminary Examples From Northwest Europe And Southeast Australia, S. K. Haslett, Edward A. Bryant, R. H. Curr

Faculty of Science - Papers (Archive)

Foraminifera are marine Sarcodine Protozoa that possess tests (shells) that are preservable in the fossil record. These tests may either be constructed using organically cemented detritus (agglutinating or arenaceous forms), or secreted using calcium carbonate (calcareous forms). Their ecology embraces planktonic and benthonic modes, although planktonic forms generally inhabit the open ocean and seldom live in coastal waters in any abundance, while benthonic foraminifera exist on substrates from abyssal plains to high intertidal areas. There are many species of foraminifera that are niche-specific, making them ideal for palaeoenvironmental analysis (Boersma, 1978; Brasier, 1980; Murray, 1991; Culver, 1993).

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 Jan 2000

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 ...


Ventilatory Accommodation Of Oxygen Demand And Respiratory Water Loss In Kangaroos From Mesic And Arid Environments, The Eastern Grey Kangaroo (Macropus Giganteus) And The Red Kangaroo (Macropus Rufus), Terence J. Dawson, Adam J. Munn, Cyntina E. Blaney, Andrew Krockenberger, Shane K. Maloney Jan 2000

Ventilatory Accommodation Of Oxygen Demand And Respiratory Water Loss In Kangaroos From Mesic And Arid Environments, The Eastern Grey Kangaroo (Macropus Giganteus) And The Red Kangaroo (Macropus Rufus), Terence J. Dawson, Adam J. Munn, Cyntina E. Blaney, Andrew Krockenberger, Shane K. Maloney

Faculty of Science - Papers (Archive)

We studied ventilation in kangaroos from mesic and arid environments, the eastern grey kangaroo (Macropus giganteus) and the red kangaroo (Macropus rufus), respectively, within the range of ambient temperatures (T-a) from -5 degrees to 45 degrees C. At thermoneutral temperatures (T-a = 25 degrees C), there were no differences between the species in respiratory frequency, tidal volume, total ventilation, or oxygen extraction. The ventilatory patterns of the kangaroos were markedly different from those predicted from the allometric equation derived for placentals. The kangaroos had low respiratory frequencies and higher tidal volumes, even when adjustment was made for their lower basal metabolism ...


Enhanced Tumor Growth In Uv-Irradiated Skin Is Associated With An Influx Of Inflammatory Cells Into The Epidermis, Ronald Sluyter, Gary M. Halliday Jan 2000

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 ...

A Novel Method For Loss Minimization In Distribution Networks, Kashem M. Muttaqi, Velappa Ganapathy, G B. Jasmon, M Buhari Jan 2000

A Novel Method For Loss Minimization In Distribution Networks, Kashem M. Muttaqi, Velappa Ganapathy, G B. Jasmon, M Buhari

Faculty of Engineering and Information Sciences - Papers: Part A

Network reconfiguration for loss minimization is the determination of switching-options that minimizes the power losses for a particular set of loads on a distribution system. In this paper, a novel method is proposed by formulating an algorithm to reconfigure distribution networks for loss minimization. An efficient technique is used to determine the switching combinations, select the status of the switches, and find the best combination of switches for minimum loss. In the first stage of the proposed algorithm, a limited number of switching combinations is generated and the best switching combination is determined. In the second stage, an extensive search ...


The Method Of Generalised Conditional Symmetries And Its Various Implementations, Joanna Goard Jan 2000

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.


Toward A Heuristic Optimum Design Of Rolling Schedules For Tandem Cold Rolling Mills, Dadong Wang, A Kiet Tieu, Friso Deboer, B Ma, W. Y. Daniel Yuen Jan 2000

Toward A Heuristic Optimum Design Of Rolling Schedules For Tandem Cold Rolling Mills, Dadong Wang, A Kiet Tieu, Friso Deboer, B Ma, W. Y. Daniel Yuen

Faculty of Engineering and Information Sciences - Papers: Part A

Scheduling for tandem cold mills refers to the determination of inter-stand gauges, tensions and speeds of a specified product. Optimal schedules should result in maximized throughput and minimized operating cost. This paper presents a genetic algorithm based optimization procedure for the scheduling of tandem cold rolling mills. The optimization procedure initiates searching from a logical staring point - an empirical rolling schedule - and ends with an optimum cost. Cost functions are constructed to heuristically direct the genetic algorithm's searching, based on the consideration of power distribution, tension, strip flatness and rolling constraints. Numerical experiments have shown that the proposed method ...


Induced C*-Algebras, Coactions And Equivariance In The Symmetric Imprimitivity Theorem, Siegfried Echterhoff, Iain Raeburn Jan 2000

Induced C*-Algebras, Coactions And Equivariance In The Symmetric Imprimitivity Theorem, Siegfried Echterhoff, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

The symmetric imprimitivity theorem provides a Morita equivalence between two crossed products of induced C*-algebras and includes as special cases many other important Morita equivalences such as Green's imprimitivity theorem. We show that the symmetric imprimitivity theorem is compatible with various inflated actions and coactions on the crossed products.

The C*-Algebras Of Row-Finite Graphs, Teresa Bates, David Pask, Iain Raeburn, Wojciech Szymanski Jan 2000

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.


The C*-Algebras Of Infinite Graphs, Neal J. Fowler, Marcelo Laca, Iain Raeburn Jan 2000

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.


Simulated Annealing With An Optimal Fixed Temperature, Mark James Fielding Jan 2000

Simulated Annealing With An Optimal Fixed Temperature, Mark James Fielding

Faculty of Engineering and Information Sciences - Papers: Part A

Contrary to conventional belief, it turns out that in some problem instances of moderate size, fixed temperature simulated annealing algorithms based on a heuristic formula for determining the optimal temperature can be superior to algorithms based on cooling. Such a heuristic formula, however, often seems elusive. In practical cases considered we include instances of traveling salesman, quadratic assignment, and graph partitioning problems, where we obtain results that compare favorably to the ones known in the literature.


Specific Yield For A Two-Dimensional Flow, Peter Tritscher, W Wayne Read, Philip Broadbridge Jan 2000

Specific Yield For A Two-Dimensional Flow, Peter Tritscher, W Wayne Read, Philip Broadbridge

Faculty of Engineering and Information Sciences - Papers: Part A

We investigate the systematic secular spatial variation of specific yield. As a vehicle for this analysis we consider a canonical unconfined aquifer consisting of a porous zone whose cross section is a simple long rectangle. The hydraulic conductivity in the unsaturated zone is modeled by the quasi-linear approximation. We find that locally the specific yield may be strongly influenced by the water table depth and mildly dependent on the recharge rate if that rate is high. For the simple geometry considered, a lateral component of flow has been found to have an insignificant effect on the local specific yield and ...


The Effect Of Different Rotation Patterns On The Revisions Of Trend Estimates, David G. Steel, Craig H. Mclaren Jan 2000

The Effect Of Different Rotation Patterns On The Revisions Of Trend Estimates, David G. Steel, Craig H. Mclaren

Faculty of Engineering and Information Sciences - Papers: Part A

The X11 and X11ARIMA procedures are widely used to produce seasonally adjusted and trend estimates from time series obtained from sample surveys. The surveys are often based on designs in which there is sample overlap between different periods. The degree of overlap is determined by the pattern of inclusion of selected units over time, i.e., the rotation pattern. An important issue in analysing the series is that trend estimates at the end of the series are revised as estimates for recent periods are added. This article considers the effects of different rotation patterns on the mean squared error of ...


Celebrating The Past: Financial Management In The Third Sectore, Anne Abraham Jan 2000

Celebrating The Past: Financial Management In The Third Sectore, Anne Abraham

Faculty of Commerce - Papers (Archive)

The centrality of the mission, as opposed to the importance of fmancial outcomes, created many problems in the early financial management of third sector organisations. Thus, it is important to celebrate the contribution made by these early managers as they struggled to guide their organisation in a fiscally responsible manner. This paper has two parts. First, it considers the need for accountability from an internal organisational perspective and also as a response to the external demand for accountability. Secondly, it provides a case study of an eighty year old organisation whose early leaders were responsible for putting in place procedures ...
