A Grounded Theory Of The Leadership Process In A Large Government Bureaucracy, George K. Kriflik, R. Jones Dec 2002

A Grounded Theory Of The Leadership Process In A Large Government Bureaucracy, George K. Kriflik, R. Jones

Faculty of Commerce - Papers (Archive)

This paper presents a theory of the leadership process within the particular substantive setting of a large government bureaucracy. The study organisation (labelled AGRO) possesses a dominant engineering culture and has a history characterised by non- tumultuous change. The research methodology of orthodox grounded theory was employed. The main concern of the participants was found to be a desire to close the gap between their current work reality and that level they perceived themselves to be capable of achieving. This was resolved through the basic social process of Minimising Attainment Deficit. Leadership aspects of charisma and vision where not evident ...


Strategic Brand Image Analysis For Heterogeneous Markets – Applying Dynamic Perceptions Based Market Segmentation (Dynpbms) To Dishwashing Brand Data, Sara Dolnicar Dec 2002

Strategic Brand Image Analysis For Heterogeneous Markets – Applying Dynamic Perceptions Based Market Segmentation (Dynpbms) To Dishwashing Brand Data, Sara Dolnicar

Faculty of Commerce - Papers (Archive)

The aim of this article is to illustrate the usefulness of an exploratory tool called dynamic perceptions based market segmentation (dynPBMS, based on the PBMS approach introduced by Mazanec and Strasser (2000) and Buchta, Dolnicar and Reutterer (2000)) for the investigation of image patterns in the marketplace as well as structural changes of such patterns over time. As starting point for analysis typical brand image data is used: repeated surveys questioning respondents about their evaluation of multiple brands with regard to multiple attributes. The advantages of using dynPBMS as compared to traditional tools applied in market structure analysis include (1 ...


A Review Of Unquestioned Standards In Using Cluster Analysis For Data-Driven Market Segmentation, Sara Dolnicar Dec 2002

A Review Of Unquestioned Standards In Using Cluster Analysis For Data-Driven Market Segmentation, Sara Dolnicar

Faculty of Commerce - Papers (Archive)

Clustering is a highly popular and widely used tool for identifying or constructing databased market segments. Over decades of applying cluster analytical procedures for the purpose of searching for homogeneous subgroups among consumers, questionable standards of utilization have emerged, e.g. the non-explorative manner in which results from cluster analytic procedures are reported, the black-box approach ignoring crucial parameters of the algorithms applied or the lack of harmonization of methodology chosen and data conditions. The purpose of this study is threefold: (1) to investigate whether and which standards of application of cluster analysis have emerged in the academic marketing literature ...


Dilemmas Of Defending Dissent: The Dismissal Of Ted Steele From The University Of Wollongong, Brian Martin Dec 2002

Dilemmas Of Defending Dissent: The Dismissal Of Ted Steele From The University Of Wollongong, Brian Martin

Faculty of Arts - Papers (Archive)

The summary dismissal of Ted Steele from the University of Wollongong in February 2001 was the most significant case of its type in Australian higher education in half a century. The Steele dismissal case is placed in the context of academic freedom in Australia, the development of the University of Wollongong and Steele's own background. The moves made by key players in the drama - the university administration, the National Tertiary Education Union, the Department of Biological Sciences and Steele - are assessed in the light of possible alternatives. The case shows that rhetoric about free speech and academic freedom provides ...


Quality Assurance And Online Teaching And Learning: First Steps, Robert M. Corderoy, Ray Stace, R. Pennell Dec 2002

Quality Assurance And Online Teaching And Learning: First Steps, Robert M. Corderoy, Ray Stace, R. Pennell

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

In the late 90s the University of Wollongong (Australia) recognised the need for the establishment of flexible course delivery. The increasing globalisation of the world of tertiary education has added to the pressure for all institutions to address issues associated with the delivery of a quality education. Many systems have been developed internationally, but to be truly useful in changing the process and ensuring the students (the clients) are happy, quality assurance has to have a local component. To address the issue of QA and online teaching and learning the authors are looking at a two phase process, the first ...


The Changing Role Of Tutors: Forming A Community Of Practice In A Distributed Learning Environment, Geraldine E. Lefoe, J. Hedberg, C. Gunn Dec 2002

The Changing Role Of Tutors: Forming A Community Of Practice In A Distributed Learning Environment, Geraldine E. Lefoe, J. Hedberg, C. Gunn

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

An evaluation of a distributed learning environment (DLE) of a regional NSW university provided the context to examine the changing role of tutors in new learning environments. It examines how the tutors started to form a community of practice in the first year of operation. The distance from the main campus made communication difficult for the tutors, lecturers and students and the use of information and communication technologies (ICT), at times, added to the challenge. This paper identifies ways that the tutor role changes in a DLE and how the development of a community of practice can support this change.


Adaptive Management: What Does It Mean And How Can It Be Used In Fire Management?, R. J. Whelan Oct 2002

Adaptive Management: What Does It Mean And How Can It Be Used In Fire Management?, R. J. Whelan

Faculty of Science - Papers (Archive)

‘Adaptive Management’ is becoming a frequently heard term but it is a much misunderstood concept. It does not mean that developments can go ahead and be ‘adapted’ if detrimental effects are discovered! Its greatest value is in defining an experimental approach to land management in situations where scientific knowledge is lacking but where immediate actions are required. This is especially important where doing nothing might conceivably be just as undesirable as applying any of the alternative management options. Given the lack of knowledge of fire responses of much of our native biota, adaptive management is clearly a sensible approach to ...


Activity-Based Market Sub-Segmentation Of Cultural Tourists, Sara Dolnicar Aug 2002

Activity-Based Market Sub-Segmentation Of Cultural Tourists, Sara Dolnicar

Faculty of Commerce - Papers (Archive)

The group of cultural tourists has received a lot of attention in the past decades. Nevertheless only few attempts have been made to study the characteristics of the “culture tourism market segment”. Besides, it is often implicitly assumed that this segment is a homogeneous group of tourists. The contribution of this article is twofold: First, the assumption of one homogeneous market segment is questioned by searching for sub-segment among cultural tourist in a data-driven manner. Second, this data partitioning task is achieved by using a topology representing network (TRN), methodology that allows additional insight into the similarity structure of the ...


Minding Your Own Business: Can A Business Excellence Framework Translate To The Education Sector? , Margie H. Jantti Jul 2002

Minding Your Own Business: Can A Business Excellence Framework Translate To The Education Sector? , Margie H. Jantti

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

As the first education and training organisation to be recognised with an Australian Business Excellence Award in the Award’s 14 year history, the University of Wollongong Library has demonstrated how the principles of excellence can readily be translated to the education and service sector.

Many higher education institutions are planning or preparing for the audit process developed by the Australian Universities Quality Agency (AUQA). The audit process, particularly the internal self assessment will be firmly focussed on practices and processes aligned with the stated vision and mission of the institution; how plans and objectives are translated into operational activities ...


Serve Sizes Of Grain Based Foods In Australia, P. G. Williams, B. Gibson, N. Smith Jul 2002

Serve Sizes Of Grain Based Foods In Australia, P. G. Williams, B. Gibson, N. Smith

Faculty of Health and Behavioural Sciences - Papers (Archive)

A survey was conducted of the recommended serve sizes used on the labelling of 807 grain based foods sold in Sydney stores in 2000. These values were compared with the serve sizes used in a variety of food selection guides, including the Australian Guide to Health Eating (AGHE). In most food categories there was a great deal of variation in the serve sizes recommended, sometimes up to 20 fold. The most consistent recommendations were for sliced breads, with most manufacturers recommending two slices as a serve, and ready-to-eat breakfast cereals (one cup). The median values for cereal products were mostly ...


Online Role Play As A Complementary Learning Design For The First Fleet Database, Sandra Wills, A. Ip Jul 2002

Online Role Play As A Complementary Learning Design For The First Fleet Database, Sandra Wills, A. Ip

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

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. The online version of the First Fleet Database has removed this obstacle, but students’ research skills still appear to be limited. Other pedagogical strategies have been added to that of the database strategy, for example a discussion forum to enable learners to publish and debate their opinions on history. However our statistics show ...

Streptococcus Pyogenes Prtfii, But Not Sfbi, Sfbii Or Fbp54, Is Represented More Frequently Among Invasive-Disease Isolates Of Tropical Australia, A. Delvecchio, B. J. Currie, Jason D. Mcarthur, Mark J. Walker, K. S. Sriprakash Jun 2002

Streptococcus Pyogenes Prtfii, But Not Sfbi, Sfbii Or Fbp54, Is Represented More Frequently Among Invasive-Disease Isolates Of Tropical Australia, A. Delvecchio, B. J. Currie, Jason D. Mcarthur, Mark J. Walker, K. S. Sriprakash

Faculty of Science - Papers (Archive)

Streptococcus pyogenes (group A streptococcus) strains may express several distinct ®bronectinbinding proteins (FBPs) which are considered as major streptococcal adhesins. Of the FBPs, SfbI was shown in Šitro to promote internalization of the bacterium into host cells and has been implicated in persistence. In the tropical Northern Territory, where group A streptococcal infection is common, multiple genotypes of the organism were found among isolates from invasive disease cases and no dominant strains were observed. To determine whether any FBPs is associated with invasive disease propensity of S. pyogenes, we have screened streptococcal isolates from bacteraemic and necrotizing fasciitis patients and ...


The Legitimizing Power Of Financial Statements In The Salvation Army In England, 1865 - 1892, H. J. Irvine Jun 2002

The Legitimizing Power Of Financial Statements In The Salvation Army In England, 1865 - 1892, H. J. Irvine

Faculty of Commerce - Papers (Archive)

Since its inception The Salvation Army has relied heavily on external funds to survive. There is evidence to suggest that at the time of its founding, in 19th century England, and in its early years, financial statements played a powerful legitimizing role. This was crucial to an organization like The Salvation Army, newly formed and in desperate need of funds. This view is consistent with institutional theory, which emphasizes the importance of such legitimacy. However, it challenges the notion, prevalent in academic literature on accounting in religious organizations, that there is a resistance to the use of accounting as a ...


Aerosol Optical Depth At Cape Grim, Tasmania 1986-1999, Stephen R. Wilson, B. W. Forgan Apr 2002

Aerosol Optical Depth At Cape Grim, Tasmania 1986-1999, Stephen R. Wilson, B. W. Forgan

Faculty of Science - Papers (Archive)

The aerosol optical depth at 4 wavelengths (368, 500, 778 and 868nm) has been measured automatically at Cape Grim since 1986. The site, on the northwest tip of Tasmania, Australia was chosen to be representative of much of the southern ocean. Fourteen years of measurement have been calibrated and analyzed. The data have been filtered so that only measurements made under on-shore wind conditions are considered. The major feature observed in the record is the eruption of Mt Pinatubo, which resulted in the aerosol optical depth at 500 nm rising to 0.2 – 0.3. If the period of high ...


Random Selection Of Citizens For Technological Decision Making, L. Carson, Brian Martin Apr 2002

Random Selection Of Citizens For Technological Decision Making, L. Carson, Brian Martin

Faculty of Arts - Papers (Archive)

Random selection provides a way to overcome some of the usual problems of citizen participation in technological decision making. It offers representativeness with a minimum of bias and susceptibility to vested interests. There are a number of requirements for the effectiveness of the random selection approach, such as that citizens are interested and capable of rational deliberation. A number of recent experiments with policy juries and planning cells are assessed to see how well they satisfy the requirements for the effectiveness of the approach. While random selection shows great promise as a means for involving citizens in technological decision making ...


Long- And Short-Run Determinants Of The Demand For Money In New Zealand: A Cointegration Analysis, Abbas Valadkhani Mar 2002

Long- And Short-Run Determinants Of The Demand For Money In New Zealand: A Cointegration Analysis, Abbas Valadkhani

Faculty of Commerce - Papers (Archive)

The existence of a stable demand for money is very important for the conduct of monetary policy even in this new era of inflation targeting. It is argued that previous work on the demand for money in New Zealand has been either not very satisfactory in a number of ways or outdated. This paper examines the long-run determinants of the demand for M3 employing the Johansen cointegration technique and quarterly data for the period 1988:1-2002:2. This paper finds, inter alia, that the demand for money is cointegrated with real income, the spread between interest on money and on ...


Assessing The Impact Of Change In Petroleum Prices On Inflation And Household Expenditures In Australia, Abbas Valadkhani, W. F. Mitchell Mar 2002

Assessing The Impact Of Change In Petroleum Prices On Inflation And Household Expenditures In Australia, Abbas Valadkhani, W. F. Mitchell

Faculty of Commerce - Papers (Archive)

In this paper we examine three broad issues: (a) the expected impact of the recent petrol price rises on prices throughout the economy, (b) the hypothesis that the economy is now less susceptible to oil price rises than it was in the 1970s when the first major oil prices occurred, and (c) the likely distributional impacts of the petrol price rises? A modified input-output (IO) price model is used to simulate the impact of a two-fold increase in petrol prices on the sectoral and aggregate price indices in Australia. The 1996-97 and 1977-78 IO tables are used. Among the results ...


An Examination Of Indexes For Determining The Number Of Clusters In Binary Data Sets, E. Dimitriadou, Sara Dolnicar, A. Weingessel Mar 2002

An Examination Of Indexes For Determining The Number Of Clusters In Binary Data Sets, E. Dimitriadou, Sara Dolnicar, A. Weingessel

Faculty of Commerce - Papers (Archive)

The problem of choosing the correct number of clusters is as old as cluster analysis itself. A number of authors have suggested various indexes to facilitate this crucial decision. One of the most extensive comparative studies of indexes was conducted by Milligan & Cooper (1985). The present piece of work pursues the same goal under different conditions. In contrast to Milligan and Cooper's work, the emphasis here is on high-dimensional empirical binary data. Binary artificial data sets are constructed to reflect features typically encountered in real-world situations in the field of marketing research. The simulation includes 162 binary data sets ...

Mildly Acidic Ph Activates The Extracellular Molecular Chaperone Clusterin, Stephen Poon, M. S. Rybchyn, S. B. Easterbrook-Smith, J. A. Carver, G. J. Pankhurst, Mark R. Wilson Jan 2002

Mildly Acidic Ph Activates The Extracellular Molecular Chaperone Clusterin, Stephen Poon, M. S. Rybchyn, S. B. Easterbrook-Smith, J. A. Carver, G. J. Pankhurst, Mark R. Wilson

Faculty of Science - Papers (Archive)

Many features of the chaperone action of clusterin are similar to those of the intracellular small heat shock proteins (sHSPs) which, like clusterin, exist in solution as heterogeneous aggregates. Increased temperature induces dissociation of some sHSP aggregates and an enhanced chaperone action, suggesting that a dissociated form is the active chaperone species. We recently reported that clusterin aggregates dissociate at mildly acidic pH. To further explore the similarities between clusterin and the sHSPs, we tested the effects of temperature and pH on the structure of clusterin and its chaperone action. Our results demonstrate that increased temperature does not induce dissociation ...


Surface Reflectance Properties Of Antarctic Moss And Their Relationship To Plant Species, Pigment Composition And Photosynthetic Function, C. E. Lovelock, Sharon A. Robinson Jan 2002

Surface Reflectance Properties Of Antarctic Moss And Their Relationship To Plant Species, Pigment Composition And Photosynthetic Function, C. E. Lovelock, Sharon A. Robinson

Faculty of Science - Papers (Archive)

We investigated how surface reflectance properties and pigment concentrations of Antarctic moss varied over species, sites, microtopography, and with water content. We found that species had significantly different surface reflectance properties, particularly in the region of the red edge (approximately 700 nm), but this did not correlate strongly with pigment concentrations. Surface reflectance of moss also varied in the visible region and in the characteristics of the red edge over different sites. Reflectance parameters, such as the Photochemical Reflectance Index (PRI) and Cold Hard Band (CBH) were useful discriminators of site, microtopographic position and water content. The PRI was correlated ...


Was The Ad 1607 Coastal Flooding Event In The Severn Estuary And Bristol Channel (Uk) Due To A Tsunami?, Edward A. Bryant, S. K. Haslett Jan 2002

Was The Ad 1607 Coastal Flooding Event In The Severn Estuary And Bristol Channel (Uk) Due To A Tsunami?, Edward A. Bryant, S. K. Haslett

Faculty of Science - Papers (Archive)

Extensive coastal lowlands known as Levels border the Severn Estuary and Bristol Channel in southwest Britain. The Levels are the result of many years of salt marsh reclamation, apparently initiated during the Roman Period, through a programme of sea bank construction. The altitude of the Levels is typically between 5-6 m Ordnance Datum (OD), an altitude that is below the current Mean High Water Springs level in the Severn Estuary. Therefore, the Levels are vulnerable to flooding, not only from river sources, but also from the sea at times when sea banks are overtopped and/or breached. A number of ...


Considerations For Capping Metal-Contaminated Sediments In Dynamic Estuarine Environments, Stuart L. Simpson, Ian D. Pryor, Ben R. Mewburn, Graeme E. Batley, Dianne F. Jolley Jan 2002

Considerations For Capping Metal-Contaminated Sediments In Dynamic Estuarine Environments, Stuart L. Simpson, Ian D. Pryor, Ben R. Mewburn, Graeme E. Batley, Dianne F. Jolley

Faculty of Science - Papers (Archive)

The effects of tides, bioturbating organisms and periods of anoxia on metal fluxes from contaminated harbour sediments in a shallow tidal estuarine bay were studied, together with capping technology options for the containment of metal contaminants. Zinc fluxes from the sediments were high, ranging from 10 to 89 mg Zn /m2/day. In the absence of capping, experiments in corer reactors showed that simulated tidal processes increased zinc fluxes 5- fold. Fluxes were also greater in the presence of sediment-dwelling organisms. If organisms were removed, and recolonising organisms later added, their bioturbation activities initially lowered zinc fluxes, but fluxes ...


Synthesis Of Chiral Allylic Amines Via Palladium(0) Catalysed Allylations Of Allylic Carbonates With Chiral Sulfinamide Anions, Zemin Dong, Stephen G. Pyne Jan 2002

Synthesis Of Chiral Allylic Amines Via Palladium(0) Catalysed Allylations Of Allylic Carbonates With Chiral Sulfinamide Anions, Zemin Dong, Stephen G. Pyne

Faculty of Science - Papers (Archive)

The palladium(0) catalysed allylation reactions of allylic carbonates with chiral sulfinamide anions to give unstable allylic sulfinamide products are described. These products are readily converted to stable, chiral N-benzoyl or N-tosyl allylic amine derivatives with poor to modest enantiomeric purities (ee 23-41%).

Thermal Protective Clothing And Cardiovascular Function, Alison L. Fogarty, Karen A. Armstrong, Christopher Gordon, Herb Groeller, Brian F. Woods, Jodie M. Stocks, Nigel A. S Taylor

Faculty of Science - Papers (Archive)

While the primary purpose of thennal protective uniforms is to minimise heat loading from hostile working environments, such uniforms also add to the physiological load by increasing metabolic rate, and limiting evaporative heat dissipation (I). Before one can provide physiological specifications for the design of thennal protective garments, one requires a thorough understanding ofthe physiological effects of wearing such unifonns. However, research in this area is dominated by field studies, with few cardiovascular variables being investigated. These field studies, while important, often bypass clothing trials under controlled laboratory conditions. As a consequence, very little is known about the cardiac output ...

Numerical Investigation Of A Reaction In A Batch Reactor: Flammability Limits, M. J Sexton, Harvinder Sidhu, Mark Nelson Jan 2002

Numerical Investigation Of A Reaction In A Batch Reactor: Flammability Limits, M. J Sexton, Harvinder Sidhu, Mark Nelson

Faculty of Engineering and Information Sciences - Papers: Part A

We study the spatial behaviour of the hydrogen-chlorine reaction in a batch reactor. The solutions exhibit regimes of slow and fast reaction. The main aim of this work is to distinguish between flaming and non-flaming mixtures from the numerical solutions. After setting out a practical criterion for flammability, we construct diagrams in parameter space which display the regions in which the reaction mixture is flammable.


A Distribution-Based Face/Nonface Classification Technique, Son Lam Phung, Douglas Chai, Abdesselam Bouzerdoum Jan 2002

A Distribution-Based Face/Nonface Classification Technique, Son Lam Phung, Douglas Chai, Abdesselam Bouzerdoum

Faculty of Engineering and Information Sciences - Papers: Part A

The core element of many existing approaches to face detection is the classification algorithm that determines if a sub-image of an input image contains a face pattern. In this paper, we present a novel and effective distribution-based face/non-face classification technique that detects frontal face patterns with possible in-plane rotation. A 15x15 input sub-image is first processed by a color filter, which verifies the presence of human skin color in the sub-image. Then, the intensity image is extracted from the identified skin color sub-image and converted into a vector in a high-dimensional space (R225). Principal component analysis is employed ...
