Theory Of Gaussian Variational Approximation For A Poisson Mixed Model, Peter Hall, J T. Ormerod, M P. Wand
Theory Of Gaussian Variational Approximation For A Poisson Mixed Model, Peter Hall, J T. Ormerod, M P. Wand
Faculty of Informatics - Papers (Archive)
Likelihood-based inference for the parameters of generalized linear mixed models is hindered by the presence of intractable integrals. Gaussian variational approximation provides a fast and effective means of approximate inference. We provide some theory for this type of approximation for a simple Poisson mixed model. In particular, we establish consistency at rate m−1/2 +n−1, where m is the number of groups and n is the number of repeated measurements.

Background Inadequate consumption of dairy products without appropriate dietary substitution may have deleterious health consequences. Social research reveals the factors that may impede compliance with dietary recommendations. This is particularly important given the recent introduction of functional dairy products. One of the challenges for public health professionals is to demonstrate the efficacy of nutrition education in improving attitudes toward nutrient rich foods. The aim of this study was to explore the salient beliefs of adult weight loss trial participants regarding both traditional and functional dairy products and to compare these with a control group not exposed to nutrition education Methods …

There has been limited research examining the impact of clients’ behavioural beliefs on whether they intend to access further treatment following residential drug and alcohol detoxification. Treatment post-detoxification is generally recommended to reduce relapse and for more sustained positive outcomes. The present pilot study examined the extent to which (1) primary components of the Theory of Planned Behaviour (TPB), (2) perceived barriers to accessing treatment and (3) the participants’ previous involvement in substance abuse treatment predicted intentions to enter further treatment following residential detoxification. One hundred and sixty eight participants accessing Salvation Army detoxification units in Australia completed a survey …
Radical Uncertainty: Judith Butler And A Theory Of Character, Shady E. Cosgrove
Radical Uncertainty: Judith Butler And A Theory Of Character, Shady E. Cosgrove
Faculty of Creative Arts - Papers (Archive)
This paper will develop a theory of character based on Judith Butler's ideas of subjectivity and gender construction. It will summarise Butler's position and explore the practicalities of reading realist characters as performative repetitions. Then, it will discuss Butler's notion of agency and the subversive repetition, and how realist characters can demonstrate the radical uncertainty inherent in Butler's notion of agency s specifically when texts are rewritten in such a way that characters `question' their `original' depictions. The example of interest here will be Jean Rhys's Wide Sargasso Sea in relation to Charlotte Bronte's Jane Eyre, with particular attention paid …
Coaching With Self-Determination Theory In Mind: Using Theory To Advance Evidence-Based Coaching Practice, Gordon B. Spence, Lindsay G. Oades
Coaching With Self-Determination Theory In Mind: Using Theory To Advance Evidence-Based Coaching Practice, Gordon B. Spence, Lindsay G. Oades
Sydney Business School - Papers
The scholarly coaching literature has advanced considerably in the past decade. However, a review of the existing knowledge base suggests that coaching practice and research remains relatively uninformed by relevant psychological theory. In this paper it will be argued that Self-Determination Theory (SDT; Deci & Ryan, 1985) presents as a useful theoretical framework for coaching as it can help understand coaching practice at both macro and micro levels. The utility of SDT as a theoretical framework for coaching is explored, with particular attention given to the role that coaching would appear to play in the satisfaction of three basic psychological …
Spectral Triples: Examples And Index Theory, Alan L. Carey, John Phillips, Adam C. Rennie
Spectral Triples: Examples And Index Theory, Alan L. Carey, John Phillips, Adam C. Rennie
Faculty of Engineering and Information Sciences - Papers: Part A
The main objective of these notes is to give some intuition about spectral triples and the role they play in index theory. The notes are basically a road map, with much detail omitted. To give a complete account of all the topics covered would require at least a book, so we have opted for a sketch.

An experimental study was undertaken to examine the sorption and desorption characteristics of coal at temperatures of 35 °C, 45 °C and 55 °C. The study focused on the effect of changes in temperature and coal particle sizes on gas sorption and desorption characteristics. The coal size used ranged from fragmented coals, 16 mm, 8 mm, 2.4 mm, powdered coal of 150 μm and 54 mm core samples. The samples were tested in pressure vessels, known as “bombs”, charged with CO2 gas at different pressure levels up to a maximum of 4000 kPa. It was found that temperature has a …

Neoliberalism And The Biophysical Environment 3: Putting Theory Into Practice, Noel Castree
Neoliberalism And The Biophysical Environment 3: Putting Theory Into Practice, Noel Castree
Faculty of Social Sciences - Papers (Archive)
There now exists a significant body of theoretically informed empirical research into 'neoliberal environments'. It comprises numerous studies which together explore the connections between neoliberal principles and policies, on the one side, and the biophysical world on the other. However, making sense of them is by no means straightforward, despite their common focus on neoliberal environments. It is currently left to readers of these studies to synthesize them into a wider, joined-up account of neoliberal environments. This and two companion articles aim for precisely this sort of broad and coherent understanding. The contribution of this third instalment is twofold. First, …
Comprehensive Model Of Oxygen Steelmaking Part 2: Application Of Bloated Droplet Theory For Decarburization In Emulsion Zone, Neslihan Dogan, Geoffrey A. Brooks, Akbar Rhamdhani
Comprehensive Model Of Oxygen Steelmaking Part 2: Application Of Bloated Droplet Theory For Decarburization In Emulsion Zone, Neslihan Dogan, Geoffrey A. Brooks, Akbar Rhamdhani
Faculty of Engineering - Papers (Archive)
The development of a global model for oxygen steelmaking and its validation against industrial data was reported in Part 1 of this paper. This paper focused on the development of one sub-model on the decarburization reaction in the emulsion zone incorporating the bloated droplet theory. This paper also critically evaluated the current knowledge on the kinetics of decarburization reaction in the emulsion phase and discussed the repercussions of the new model for industrial practices. The decarburization model, in conjunction with the industrial data, indicates that the decarburization rates in the emulsion phase reaches up to approximately 60% of the overall …

Commentary On Farbstein, R. "Technologies Of Art", Katherine Szabo
Faculty of Science, Medicine and Health - Papers: part A
Chaîne opératoire, as both an analytical approach and a sociotechnical perspective, has had a presence in material culture literature for some considerable time. However despite the longevity of the concept, its full potential for the comparative study of material culture production and consumption has not really been realized within archaeology. Here, Farbstein explores this area through looking at the production of mobiliary art in a range of raw materials at Pavlovian Upper Paleolithic sites.
Considering Cognitive Load Theory Within E-Learning Environments, Abdullah Al Asraj, Mark Freeman, Paul A. Chandler
Considering Cognitive Load Theory Within E-Learning Environments, Abdullah Al Asraj, Mark Freeman, Paul A. Chandler
Faculty of Informatics - Papers (Archive)
This study seeks to investigate how cognitive load influences knowledge construction and what is the role of layered integrated instructional techniques in facilitating the construction and automation of schemas whilst users are interacting with e-learning tools. Initially the literature on how Cognitive Load Theory (CLT) plays a role in e-learning tools is presented, this is followed by the considerations that need to be taken when developing e-learning tools with CLT as a focus so that learners can gain the best possible learning outcomes. This paper finally presents three different ways that e-learning tools can be designed when considering the cognitive …

In today’s challenging business environment, organisations not only need to continue to leverage their internal sources of competitive advantage but also should strive to harness synergies across the multiple supply chains that they are part of. However, this has to be achieved through effective collaboration between partner organisations. This paper contributes to the current scholarly discourse on this topic by the application of the “Agency Theory” to the issues around supply chain integration and collaboration, towards enhancing operational performance. The paper presents a classification of supply chain integration and collaboration, as well as a conceptual framework, for understanding and explaining …

Analysis Of Bloated Droplet Theory Using Steelmaking Process Models, N Dogan, G A. Brooks, M A. Rhamdhani
Faculty of Engineering - Papers (Archive)
There is significant evidence that droplets generated in steelmaking "bloat" due to the inability of gas generated from the decarburisation reaction to escape from the surface of liquid metal droplets. A model to describe this behavior was developed by Brooks, Subagyo, Coley and Pan based on their own experimental work and calculations and previous studies by Fruehan and co-workers. This approach has been successfully incorporated into an overall process model of oxygen steelmaking. A unique feature of this model is an evaluation of the decarburization kinetics of individual metal droplets in the emulsion and comparing this to the overall kinetics …

A Comparative Study Of Three Inverse Kinematic Methods Of Serial Industrial Robot Manipulators In The Screw Theory Framework, Emre Sariyildiz, Eray Cakiray, Hakan Temeltas
A Comparative Study Of Three Inverse Kinematic Methods Of Serial Industrial Robot Manipulators In The Screw Theory Framework, Emre Sariyildiz, Eray Cakiray, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, we compare three inverse kinematic formulation methods for the serial industrial robot manipulators. All formulation methods are based on screw theory. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. In these three formulation methods, the first one is based on quaternion algebra, the second one is based on dual-quaternions, and the last one that is called exponential mapping method is based on matrix algebra. Compared with the matrix algebra, quaternion algebra based solutions are more computationally efficient and they need …
A Singularity Free Trajectory Tracking Method For The Cooperative Working Of Multi-Arm Robots Using Screw Theory, Emre Sariyildiz, Hakan Temeltas
A Singularity Free Trajectory Tracking Method For The Cooperative Working Of Multi-Arm Robots Using Screw Theory, Emre Sariyildiz, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we present a singularity free trajectory tracking method for the cooperative working of multi-arm robot manipulators. It is based on an inverse kinematic transformation which determines the manipulator's joint angles corresponding to the end-effector trajectory given in the task space. The kinematic problem of multi-arm robot system is solved by using screw theory and quaternion algebra. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. Dual-quaternion is the most compact and efficient dual operator to express screw displacement. Inverse kinematic solutions …
How To Do A Grounded Theory Study: A Worked Example Of A Study Of Dental Practices, Alexandra Sbaraini, Stacy M. Carter, R Wendell Evans, Anthony Blinkhorn
How To Do A Grounded Theory Study: A Worked Example Of A Study Of Dental Practices, Alexandra Sbaraini, Stacy M. Carter, R Wendell Evans, Anthony Blinkhorn

Qualitative methodologies are increasingly popular in medical research. Grounded theory is the methodology most-often cited by authors of qualitative studies in medicine, but it has been suggested that many 'grounded theory' studies are not concordant with the methodology. In this paper we provide a worked example of a grounded theory project. Our aim is to provide a model for practice, to connect medical researchers with a useful methodology, and to increase the quality of 'grounded theory' research published in the medical literature.
Understanding Fictional Minds Without Theory Of Mind!, Daniel Hutto
Understanding Fictional Minds Without Theory Of Mind!, Daniel Hutto
Faculty of Law, Humanities and the Arts - Papers (Archive)
This paper explores the idea that when dealing with certain kinds of narratives, ‘like it or not’, consumers of fiction will bring the same sorts of skills (or at least a subset of them) to bear that they use when dealing with actual minds. Let us call this the ‘Same Resources Thesis’. I believe the ‘Same Resources Thesis’ is true. But this is because I defend the view that engaging in narrative practices is the normal developmental route through which children acquire the capacity to make sense of what it is to act for a reason. If so, narratives are …
Anti-Representationalism: Not A Well-Founded Theory Of Cognition, Michael Kirchhoff
Anti-Representationalism: Not A Well-Founded Theory Of Cognition, Michael Kirchhoff
Faculty of Arts - Papers (Archive)
This article argues for the conclusion that anti-representationalism in the cognitivesciences is not a well-founded theory of cognition. This conclusion is supported by the observationthat the link between the sceptical demonstrations and the anti-representational conclusion is tooweak for the demonstrations to justify anti-representationalism in general. Rather than denying theneed for internal representation, this article aim to establish that representational explanation -reconstructed within a dynamical agent-environment characterization - serves a necessary epistemicand ontological aim: It enables us to demarcate activities that presuppose intentionality andbehavioral autonomy from activities that are merely reactive and situation-determined.

Given a C-algebra A with a KMS weight for a circle action, we construct and compute a secondary invariant on the equivariant K-theory of the mapping cone of AT ,! A, both in terms of equivariant KK-theory and in terms of a semifinite spectral flow. This in particular puts the previously considered examples of Cuntz algebras [10] and SUqð2Þ [14] in a general framework. As a new example we consider the Araki-Woods IIIl representations of the Fermion algebra.
