Synthesis And Hydrolytic Evaluation Of Acid-Labile Imine-Linked Cytoxic Isatin Model Systems, Lidia Matesic, Julie Locke, Kara Perrow, Marie Ranson, John Bremner, Danielle Skropeta

Danielle Skropeta

In this study a series of isatin-based, pH-sensitive aryl imine derivatives with differing aromatic substituents and substitution patterns were synthesised and their acid-catalysed hydrolysis evaluated. These derivatives were functionalised at the C3 carbonyl group of a potent N-substituted isatin cytotoxin and were stable at physiological pH but readily cleaved at pH 4.5. Observed rates of hydrolysis for the embedded imine-acid moiety were in the order para-phenylpropionic acid>phenylacetic acid (para>meta)>benzoic acid (meta>para). The ability to fine-tune hydrolysis rates in this way has potential implications for optimising imine linked, tumour targeting cytotoxin-protein conjugates


An Adaptive Bilateral Negotiation Model Based On Bayesian Learning, Chao Yu, Fenghui Ren, Minjie Zhang Oct 2013

An Adaptive Bilateral Negotiation Model Based On Bayesian Learning, Chao Yu, Fenghui Ren, Minjie Zhang

Dr Fenghui Ren

Endowing the negotiation agent with a learning ability such that a more beneficial agreement might be obtained is increasingly gaining attention in agent negotiation research community. In this paper, we propose a novel bilateral negotiation model based on Bayesian learning to enable self-interested agents to adapt negotiation strategies dynamically during the negotiation process. Specifically, we assume that two agents negotiate over a single issue based on time-dependent tactic. The learning agent has a belief about the probability distribution of its opponent's negotiation parameters (i.e., the deadline and reservation offer). By observing opponent's historical offers and comparing them with the fitted …


An Investigation On The Impacts Of Density Currents On The Sedimentation In Dam Reservoirs Using Tcm Model; Case Study: Maroon Dam, Farhad Raof, Mohammad Naghshine, Ali Khoshrftar Sep 2013

An Investigation On The Impacts Of Density Currents On The Sedimentation In Dam Reservoirs Using Tcm Model; Case Study: Maroon Dam, Farhad Raof, Mohammad Naghshine, Ali Khoshrftar

Farhad Fakheri Raof

Sedimentation in dams' reservoirs is one of the most pressing concerns facing dams today. Maroon reservoir dam, located in Khuzestan Province, is one of the most important dams in this region. Since it is a new constructed dam, numerical simulation of sedimentation trend in its reservoirs could significantly help on a better utilization. To this end, TCM model which is capable to simulate density currents was used. The obtained results show that the dam loses about 91 million m3 of its reservoirs during a 50-year exploitation period.


Beyond The Rhetoric: What Do We Mean By A 'Model Of Care'?, Patricia Davidson, Elizabeth Halcomb, L Hickman, J Phillips, B Graham Jul 2013

Beyond The Rhetoric: What Do We Mean By A 'Model Of Care'?, Patricia Davidson, Elizabeth Halcomb, L Hickman, J Phillips, B Graham

Elizabeth Jane Halcomb Professor

Background: Contemporary health care systems are constantly challenged to revise traditional methods of health care delivery. These challenges are multifaceted and stem from: (1) novel pharmacological and non-pharmacological treatments; (2) changes in consumer demands and expectations; (3) fiscal and resource constraints; (4) changes in societal demographics in particular the ageing of society; (5) an increasing burden of chronic disease; (6) documentation of limitations in traditional health care delivery; (7) increased emphasis on transparency, accountability, evidence-based practice (EBP) and clinical governance structures; and (8) the increasing cultural diversity of the community. These challenges provoke discussion of potential alternative models of care, …

The Exchange was designed to provide access to a repository of shared learning and teaching resources, work spaces for team members engaged in collaborative projects, and communication and networking services. The Australian Learning and Teaching Council (ALTC) established the Exchange for those who teach, manage and lead learning and teaching in higher education. As part of the research conducted to inform the development of the Exchange, models for peer review of educational resources were evaluated. For this, a design based research approach …


The Development Of An Industry Specific Performance Measurement Model For Service Organisations Within The Small Business Sector, Vicki Baard, Edmund W. Watts Jul 2013

The Development Of An Industry Specific Performance Measurement Model For Service Organisations Within The Small Business Sector, Vicki Baard, Edmund W. Watts

Ted Watts

The role of small business, as part of the value adding chain in any economy, should never be understated. In Australia small business represents 96% of all private sector business, accounts for 47% of all private sector employment and the majority fail within three to five years of establishment. Despite this contribution the small business sector, and in particular the service sector component, appear to be underrepresented in the development of specific performance measurement models, which, within the academic and professional literature appear to focus on their larger firm counterparts. Given the unique position of small business service organisations the …


A Model For Corporate Governance, Decision-Making, And Accountability In Today's Universities, Jack Flanagan, John Little, Edmund W. Watts Jul 2013

A Model For Corporate Governance, Decision-Making, And Accountability In Today's Universities, Jack Flanagan, John Little, Edmund W. Watts

Ted Watts

The government’s goal over the past decade of increased self-reliance has required universities to adopt the corporate mantle of governance consistent with that used in the private sector. The corporatisation of the university sector brought with it a unique set of problems to which senior university management had not previously been exposed. The solution to some of these problems includes developing governance systems to guide strategic decision-making based on well-developed ethical principles. This paper suggests such an approach to governance based on contemporary management and ethical foundations. In this model governance is depicted as an achievement of thinking across four …


Combining The Health Belief Model And Social Marketing To Develop A Community-Level Campaign About Asthma For Older Adults, Uwana Evers, Sandra C. Jones, Peter Caputi, Donald C. Iverson Jul 2013

Combining The Health Belief Model And Social Marketing To Develop A Community-Level Campaign About Asthma For Older Adults, Uwana Evers, Sandra C. Jones, Peter Caputi, Donald C. Iverson

Sandra Jones

This conceptual paper provides a rationale for combining health behaviour theory with a social marketing framework in order to develop a community-level asthma campaign for adults aged 55 years and older. The prevalence of asthma in older adults in Australia is approximately 10%, higher than in many other countries, and asthma mortality increases with age. In addition, older adults' perceptions of asthma causes and treatments are often inaccurate. Many older adults believe that asthma is a childhood disease and that the effects of the condition are relatively minor and would not impact on daily life. In order to address these …


Ward Rounds: Developing A Collaborative Best Practice Model Of Interdisciplinary Teaching For Multidisciplinary Practice, Patrea Andersen, Noel Tait, Kenneth Walsh, Pauline Gaetani, Alison Jones, Angela Brown Jun 2013

Ward Rounds: Developing A Collaborative Best Practice Model Of Interdisciplinary Teaching For Multidisciplinary Practice, Patrea Andersen, Noel Tait, Kenneth Walsh, Pauline Gaetani, Alison Jones, Angela Brown

Alison L Jones

Ward rounds are an everyday occurrence in clinical practice. They provide the means for assessing patient care needs and communicating these within a multidisciplinary team. The literature demonstrates poor ward round practice contributes to poor patient care outcomes (O'Hare, 2008). Garling (2008) identifies that there is a need to change current practise and facilitate more effective interdisciplinary communication. This presentation reports collaborative research between The Illawarra Shoalhaven Local Health District (ISL HD) and The University of Wollongong. Using a Practice Development methodology, the aim of the research is to develop and test a best practice model for conducting ward rounds …


Assessing Soil Remobilisation In Catchments Using A 137 Cs-Sediment Hillslope Model, Ava D. Simms, Colin D. Woodroffe, Brian G. Jones, Henk Heijnis, Jennifer Harrison, Rob Mann Jun 2013

Assessing Soil Remobilisation In Catchments Using A 137 Cs-Sediment Hillslope Model, Ava D. Simms, Colin D. Woodroffe, Brian G. Jones, Henk Heijnis, Jennifer Harrison, Rob Mann

B. G. Jones

Soil redistribution studies are important, especially in water supply catchments, because the rate at which denudation is occurring has implications for offsite water quality. However, the extent to which soil is redistributed within the landscape can be difficult to determine. This challenge can be overcome using fallout caesium-137 (137Cs). This paper describes the rates of soil loss and remobilisation in two sub-catchments within the Sydney Basin region, namely Kembla and Kentish Creeks, which drain to the Cordeaux reservoir. The total inventories of 137Cs in catchment soils were determined, a 137Cs-regression equation and a theoretical diffusion and migration model were used …


Studying The Impact Of The Corner Propagation Model On Vanet Routing In Urban Environments, Abhinay Mukunthan, Craig Cooper, Farzad Safaei, D. Franklin, Mehran Abolhasan Jun 2013

Studying The Impact Of The Corner Propagation Model On Vanet Routing In Urban Environments, Abhinay Mukunthan, Craig Cooper, Farzad Safaei, D. Franklin, Mehran Abolhasan

Professor Farzad Safaei

Accurate modelling of the radio channel is often the most difficult aspect of a Vehicular Ad Hoc Network (VANET) simulation due to the large variability present in vehicular terrain. CORNER is a propagation model that calculates path-loss in an urban terrain with a large concentration of buildings, based on the position of the transmitter and receiver on a street map. This paper proposes additions to the CORNER propagation model to take selective multi-path fading into account and investigates the performance of the GPSR routing protocol under the CORNER propagation model in a realistic city environment.


Ignoring A Level In A Multilevel Model: Evidence From Uk Census Data, Mark Tramner, David Steel Jun 2013

Ignoring A Level In A Multilevel Model: Evidence From Uk Census Data, Mark Tramner, David Steel

Professor David Steel

Because of the inherent multilevel nature of census data, it is often appropriate to use multilevel models to investigate relationships between census variables. For a local population, the data available from the census allow a three-level nested model to be assumed, with an individual level (level 1), an enumeration district (ED) level (level 2), and a ward level (level 3). The consequences of ignoring one of the three levels in this model are assessed here theoretically. Empirical results, based on 1991 UK Census data, are also provided, comparing the variance components estimated from the three-level model with analyses based on …

Collaborative Recovery: An Integrative Model For Working With Individuals Who Experience Chronic And Recurring Mental Illness, Lindsay G. Oades, Frank P. Deane, Trevor P. Crowe, Gordon Lambert, David Kavanagh, Christopher Lloyd

Lindsay G Oades

Objectives: Recovery is an emerging movement in mental health. Evidence for recovery-based approaches is not well developed and approaches to implement recovery-oriented services are not well articulated. The collaborative recovery model (CRM) is presented as a model that assists clinicians to use evidencebased skills with consumers, in a manner consistent with the recovery movement. A current 5 year multisite Australian study to evaluate the effectiveness of CRM is briefly described. Conclusion: The collaborative recovery model puts into practice several aspects of policy regarding recovery-oriented services, using evidence-based practices to assist individuals who have chronic or recurring mental disorders (CRMD). It …

This in1 tegrated model provides a platform to evaluate ride comfort 1performance in terms of driver head acceleration responses under typical road disturbances and to develop an integrated control of seat and car suspensions. Based on the integrated model, an H∞ state feedback controller is designed …


Scouting And Servant Leadership In Cross-Cultural Perspective: An Exploratory Study, Ric Rohm, Bramwell Osula Dec 2012

Scouting And Servant Leadership In Cross-Cultural Perspective: An Exploratory Study, Ric Rohm, Bramwell Osula

Ric Rohm

This qualitative case study evaluates the World Organization of the Scout Movement (WOSM), Boy Scouts of America, Scout Association of Japan, and the four major German scouting organizations (Deutsche Pfadfinderschaft Sankt Georg, Pfadfinderinnenschaft Sankt Georg, Bund der Pfadfinderinnen und Pfadfinder, and Verband Christlicher Pfadfinderinnen und Pfadfinder) as servant leadership development programs. After a brief history of the origins of scouting, the WOSM and the three national scouting organizations are examined, comparing their mottos, promises, and laws. All programs promote service to God, country, and community; teaching leadership through outdoor living and community service projects. A review of servant leadership literature …


Word From The Chair - Feshe Fire-Ems Education, Rodger E. Broome Phd Dec 2012

Word From The Chair - Feshe Fire-Ems Education, Rodger E. Broome Phd

Rodger E. Broome

Fire and emergency services is a complex world that presents responders with problems to solve under significant time constraints. We value people who can make decisions on their feet and actualize them quickly with precision. This requires training, education, and experience (TEE).
