description: Estimating the quality of published research is important for evaluations of departments, researchers, and job candidates. Citation-based indicators sometimes support these tasks, but do not work for new articles and have low or moderate accuracy. Previous research has shown that ChatGPT can estimate the quality of research articles, with its scores correlating positively with an expert scores proxy in all fields, and often more strongly than citation-based indicators, except for clinical medicine. ChatGPT scores may therefore replace citation-based indicators for some applications. This article investigates the clinical medicine anomaly with the largest dataset yet and a more detailed analysis. The results showed that ChatGPT 4o-mini scores for articles submitted to the UK's Research Excellence Framework (REF) 2021 Unit of Assessment (UoA) 1 Clinical Medicine correlated positively (r=0.134, n=9872) with departmental mean REF scores, against a theoretical maximum correlation of r=0.226. ChatGPT 4o and 3.5 turbo also gave positive correlations. At the departmental level, mean ChatGPT scores correlated more strongly with departmental mean REF scores (r=0.395, n=31). For the 100 journals with the most articles in UoA 1, their mean ChatGPT score correlated strongly with their REF score (r=0.495) but negatively with their citation rate (r=-0.148). Journal and departmental anomalies in these results point to ChatGPT being ineffective at assessing the quality of research in prestigious medical journals or research directly affecting human health, or both. Nevertheless, the results give evidence of ChatGPT's ability to assess research quality overall for Clinical Medicine, where it might replace citation-based indicators for new research.

description: Post-developmentally, neurons are very long lived and, while shown to be capable of plasticity-promoting remodeling of dendritic structures, are thought to maintain relatively stable morphologies over long animal lifespans. The molecular mechanisms that maintain neuronal morphology remain poorly understood. Members of the highly conserved DIP2 protein family contain an N-terminal DNA methyltransferase-associated protein 1 (DMAP1) binding domain and two adenylate-forming (AFD) domains. Using two loss-of-function alleles, we show that DIP-2 acts to maintain neuronal morphology in C. elegans. dip-2 mutants display a progressive increase in ectopic neurite sprouting and branching post-development. DIP-2 acts in a DMAP1 binding-domain-independent manner to maintain neuronal morphology post-developmentally and DIP-2 overexpression can suppress the normal increase in neuronal sprouting defects observed in aging worms. Endogenous DIP-2 is widely expressed in neuronal and epithelial tissue but acts cell-autonomously in neurons. Finally, dip-2 neuronal defects are modified by loss of insulin/IGF-1 signalling (IIS) and DIP-2 acts in parallel with the SAX-2/Furry-SAX-1/NDR kinase pathway to regulate neuronal morphology.

description: This study examined the perceptions of housing transitions of individuals with histories of residential instability. Participants were recruited from the Health and Housing in Transition study (HHiT), a longitudinal multi-city Canadian study tracking the health and housing of 1,192 participants over a 5-year period. Twenty-two participants from Ottawa were recruited from the larger study to participate in the present study. Participants were interviewed using a semi-structured interview guide about their experiences of housing transitions (moves from one housing situation to another). A general inductive method for the analysis of qualitative data was used to examine participants’ perceptions of their transitions. Findings suggest that participants experienced feelings of disconnection from their housing situations. Their transitions were characterized as chaotic and initiated by factors outside of their control. Participants attributed their transitions to factors such as interpersonal issues, substance use, financial issues, safety concerns, and pests. The present study emphasizes the complexity of participants’ precarious housing situations and the multifactorial nature of their residential instability.

description: Proton transfer between the DNA bases can lead to non-standard, potentially mutagenic tautomeric forms [1, 2]. If the tautomers successfully pass through the replication machinery, they are thought to adopt a Watson-Crick-like shape and mismatch with the wrong base, thus evading proof-reading and potentially leading to replication error [3]. There is heated debate over the true biological impact of the tautomeric forms. Previously it was proposed that if the tautomeric lifetime is much shorter than the helicase cleavage time, no tautomeric population would successfully pass the enzyme [4]. Density functional theory (DFT) results suggest that the proton transfer energy landscape drastically changes during the first two Angstrom cleavage of the base. Molecular dynamics simulations indicate that cleavage time is much quicker than previously thought, with our models describing aqueous DNA. Our results indicate that a static picture of the proton transfer oversimplifies the biological event. [1] L. Slocombe, J. S. Al-Khalili, M. Sacchi, Phys. Chem. Chem.

description: Measuring terahertz waveforms in terahertz spectroscopy often relies on electrooptic sampling employing a ZnTe crystal. Although the nonlinearities in such zincblende semiconductors induced by intense terahertz pulses have been studied at optical frequencies, a quantitative study of nonlinearities in the terahertz regime has not been reported. In this work, we investigate the nonlinear response of ZnTe in the terahertz frequency region utilizing time-resolved terahertz-pump terahertz-probe spectroscopy. We find that the interaction of two co-propagating terahertz pulses in ZnTe leads to a nonlinear polarization change which modifies the electro-optic response of the medium at terahertz frequencies. We present a model for this polarization that showcases the second-order nonlinear behavior. We also determine the magnitude of the third-order susceptibility in ZnTe at terahertz frequencies, $χ^{\mathrm{(3)}}(ω_\text{THz})$. These results clarify the interactions in ZnTe at terahertz frequencies, with implications for measurements of intense terahertz fields using electro-optic sampling.

Human rights: education and implementation in a commercial organisation
Creators: name: Chambers, Angela
Publisher: name: RMIT University
Year: 2024

description: This case study explored the process of incorporating human rights into the operation of an international commercial organisation. Constructing a dialogue to bridge the gap between human rights discourse and commercial realities, this case study identified the unique roles required to develop dialogue and created a model as a diagnostic and educational tool.

The roles specific to human rights consulting, of Interpreter, Champion and Enabler afforded effective penetration into the participating industry partner's operational levels. These roles emerged from the process of constructing a human rights discourse and tensions therein where the existing theory of organisational change and consulting was found to be inadequate for human rights intervention.

Based on the data of industry partner's existing practices and human rights concerns and on the process of collecting and analysing this data, the model for education and implementation was constructed. It is a flexible tool for examining human rights practices from bottom up as well as top down of an organisation.

This research showed that having a comprehensive picture of the complexities involved sas an effective method of exploration and making sense of human rights education and implementation in a multinational industrial setting. The construction of the roles and of the model relied on the central premise of willingness of a multinational corporation to examine its practices and take an autonomous position of corporate citizenship and responsibility. This was consistent with the participatory research design of the study. Theretically this research challenges the appropriateness of traditional organisational change concepts when dealing with human rights; provides a diagnostic and educational tool for human rights consulting; and points to further research in this area.

description: We demonstrate the existence of genuine tripartite non-Gaussian entanglement in a quantum gravitational system formed by a quantum harmonic oscillator coupled to a single frequency of a quantized gravitational wave. For this purpose, we introduce a new entanglement witness, well-suited for the graviton-matter interaction Hamiltonian analysed here. We show that the witness is non-zero for the three-mode states generated by the Hamiltonian when the system starts in the ground state, thus proving the generation of genuine multipartite quantum entanglement at the most fundamental level of theoretical graviton-matter interactions.

The Effect of Wall Compliance on the Stability of Jets and Wakes
Creators: name: Poole, Ryan
Publisher: name: Zenodo
Year: 2022

description: The 1950s experiments of Kramer into modelling dolphin skin using compliant
 coatings lead to a surge in research on the validity of said experiments,
 as well as the general stability characteristics of such coatings. These stability
 characteristics were consisted by bounding channel flows by two identical compliant
 walls. This approach lead to a rich array of instabilities, since the wall
 can now carry its own wave and can thus interact with the fluid instabilities.
 In this talk, we discuss the effects of bounding a 2D jet/wake flow with two
 identical compliant walls. Dispersion relations, which are 4th order polynomials
 in the wave frequency ω, and transcendental in wave number α, are derived
 for both varicose and sinuous flows, which we use to determine the temporal
 and absolute instability characteristics of the flow for a range of flow and wall
 parameters.
 Solving the dispersion relations leads to 4 solutions, two related to the flow,
 and 2 that depend on the walls. We find the addition of the walls leads to
 additional instabilities unseen in the case when the flow is bounded by rigid
 walls, this is true for both temporal and absolute instability. We also find that
 we are able to increase and decrease the magnitude of the absolute instabilities,
 as well as increase the range of parameter space where absolute instability exists.

description: We investigate the interplay between self-duality and spatially modulated symmetry of generalized $N$-state clock models, which include the transverse-field Ising model and ordinary $N$-state clock models as special cases. The spatially modulated symmetry of the model becomes trivial when the model's parameters satisfy a specific number-theoretic relation. We find that the duality is non-invertible when the spatially modulated symmetry remains nontrivial, and show that this non-invertibility is resolved by introducing a generalized $\mathbb{Z}_N$ toric code, which manifests ultraviolet/infrared mixing, as the bulk topological order. In this framework, the boundary duality transformation corresponds to the boundary action of a bulk symmetry transformation, with the endpoint of the bulk symmetry defect realizing the boundary duality defect. Our results illuminate not only a holographic perspective on dualities but also a relationship between spatially modulated symmetry and ultraviolet/infrared mixing in one higher dimension.

description: Abstract One of the major infrastructure problems faced by the UK's railway industry is ageing railway bridges. There are more than 10,000 metallic railway bridges which have exceeded their design life of 120years, with many suffering from significant deterioration issues. To address immediate safety concerns, and to prioritise maintenance, estimation of a bridge’s residual fatigue life is a growing area of investigation by bridge owners. This has led to an increase in research collaboration between bridge asset owners and academia, particularly in trying to better understand railway bridge dynamic and fatigue related effects. This research contributes to this area or work by investigating how mathematical modelling can be used to look at complex dynamic interaction effects between the train and bridge and its impact on fatigue cumulative damage. The research fits in with the overall them of the DDC-2022 theme, ‘Exploring New Possibilities’. The research also complements the universities strategic vision for ‘Sustainability’. The research goal is to provide a methodology by which a complex engineering problem can be simplified to enable it to be used for practical engineering applications. The mathematical model which is being developed as part of this research activity will help bridge asset owners to prioritise bridge maintenance, prolonging the operational use of a bridge and ultimately to decide when a bridge should be replaced. The research therefore helps with environmental sustainability as the model can be used to maximise the use of existing bridge assets and thus eliminate untimely bridge replacement. The model, and the methodology developed in this work, has the potential for wider use in similar engineering applications.

Bond behaviour of fibre reinforced polymer strengthened concrete structures using advanced composite processing techniques
Creators: name: Hadigheh, Seyed Ali
Publisher: name: RMIT University
Year: 2024

description: The research presented in this thesis consists of experimental, analytical and numerical studies of the interface behaviour in adhesively bonded joints manufactured with common and new developed FRP processing methods. The wet lay-up and pultruded laminates are categorized as common, and vacuum assisted resin infusion (VARI) and heated vacuum bag only (HVBO) are considered as recently developed processing methods. The effect of the principal parameters on the interface behaviour is studied through several series of experiments. Local and global investigations of the interface indicate that through application of VARI and HVBO, a bond with high quality is achievable. To monitor the bond characteristics during the experiments, a new single lap shear test set-up is developed and employed in this research. Results indicate that accurate and reliable results can be achieved in terms of interfacial responses using modified single lap shear test set-up. Through the experimental program, the effect of the bondline thickness is specifically studied for different types of processing techniques. Investigation on the local and global bond parameters show that after a specific bondline thickness, load carrying capacity of the joint does not change. Therefore, a new concept, the optimum bondline thickness, is proposed and the load-bondline thickness relationships are adopted based on the nonlinear regression analysis of the experimental results. Since in this research various techniques are compared and considering this fact that the fabrication method in these techniques is different therefore, the bond characteristics are scaled in a way that the comparison can be possible.

 This scaling factor here is called “equalisation of the processing techniques.” A new analytical approach is presented for determination of the interface behaviour in FRP-to-concrete bonded joints. Based on the boundary conditions, two distinctive methods are proposed to predict the bond-slip relationships and interfacial fracture energy. Since the models are derived solely based on boundary conditions of the joints, they can be applied to any type of the FRP processing technique. In addition, the interface characteristics are obtained from the value of the applied load at each stage and the properties of the materials which are available in most of the tests. Comparison between the experimental and the analytical results of the maximum load carrying capacity, the strain, shear stress and slip profiles and also the fracture energy of the interface indicate that the proposed analytical methods are capable to predict the interfacial behaviour between the FRP and concrete substrates with satisfactory precision. Finally, considering the proper material constitutive laws, a finite element analysis is carried out and the outcomes are presented.
Sources and antecedents of brand equity for online companies
Creators: name: Rios, Rosa
Publisher: name: RMIT University
Year: 2024

description: The area of Brand Equity has received considerable attention during the past twenty years. The importance of a brand emanates from the fact that brand recognition and positive associations with it create value for companies and consumers. This value is called Brand Equity and translates into monetary value.

Until now, there is scant research on brand equity for online retailers to test whether theoretical frameworks developed for offline companies apply to online businesses. The study is an attempt to bridge this gap by developing and testing a comprehensive brand equity model with selected drivers (customer support and a mix of functionality and fulfilment marketing efforts) and sources (awareness, association of value and trust, and loyalty) of brand equity.

Grounded in a traditional offline consumer-based brand equity framework, a research model (at the aggregate level) for assessing brand equity of online companies is developed and tested using structural equation modelling (SEM).

Several key findings are reported: First, a measurement model based on dimensions of awareness, associations of value and trust, and attitudinal loyalty seem to fit the data well. Measures have adequate reliability, convergent and discriminant validity. Secondly, from the SEM application, only value association and loyalty are potent determinants of brand equity. Third, awareness, trust and value associations contribute indirectly to create brand equity. Fourth, the hierarchical hypothesized relationships between the sources of brand equity are confirmed. The final best-fitting (calibrating) model derived from the subjects that had bought from the online businesses under study was validated across a sample of subjects. Simultaneous model comparison using structural equation (by means of Chi square difference) confirms the tenability of the calibrating model. To test for the probability than an incorrect model will be rejected, power analysis was calculated. The results indicate that the likelihood of rejecting the hypothesis of exact and close fit equals 1.0.

The second phase of the study involved brand analysis at the individual level. According to the calculations Amazon obtains slightly higher brand equity than eBay and puts it in first place, eBay is in second place, followed by Dell in third. CDNow is the worst performer and obtains consumer-based brand equity below average. The study offers contributions to both academia and business in several ways.
A creative exploration of the physical and aesthetic properties inherent in painting, sculpture and architecture as applied to model animation
Creators: name: Schultz, Andrew
Publisher: name: RMIT University
Year: 2024

description: This project is a creative exploration of the physical and aesthetic properties inherent in painting, sculpture and architecture as applied to model animation.

The project focuses on a number of areas such as the sculptural quality of model animation, the lighting of model animation, the cinematography for animation, the frame by frame nature of animation, model animation environments and alternative methods for creating animation sequences.

A range of art forms have been investigated with respect to these themes. The sculptural nature of model animation has been informed by a study of the sculpture of Donatello, Rodin and Brancusi. The analysis of the lighting of model animation has been informed by a study of, amongst other things, baroque painting and Byzantine mosaics. The frame by frame nature of animation has been informed by a study of the painting techniques of Impressionism, Post Impressionism and Futurism. The research into cinematography for model animation has been informed by a study of, amongst other things, the use of ‘point of view’ in Renaissance painters such as Mantegna. The research into methods for creating animation sequences has been informed by an analysis of the use of axis and circles in architecture. As a result the project has not analysed in detail current animation practice.

description: This study investigates the influence of Herbig-Haro jets on initiating star formation in dense environments. When molecular clouds are nearing gravitational instability, the impact of a protostellar jet could provide the impetus needed to catalyze star formation. A high-energy-density experiment was carried out at the LULI2000 laser facility, where a supersonic jet generated by a nanosecond laser was used to compress a foam or plastic ball, mimicking the interaction of a Herbig-Haro jet with a molecular cloud. Simulations using the 3D radiation hydrodynamics code TROLL provided comprehensive data for analyzing ball compression and calculating jet characteristics. After applying scaling laws, similarities between stellar and experimental jets were explored. Diagnostic simulations-including density gradient, emission, and X-ray radiographies-showed strong agreement with experimental data. The results of the experiment, supported by simulations, demonstrate that the impact of a protostellar jet on a molecular cloud could reduce the Bonnor-Ebert mass by approximately 9%, thereby initiating collapse.
Lost in the Fray: discovering mimesis in an estranged world
Creators: name: Crljen, Franki
Publisher: name: RMIT University

description: Dystopian fiction achieves its creative and social-political goals when it resolves its unique tension between mimesis and estrangement. The writer must simultaneously create a world that is plausible to the reader but also unfamiliar. Not only must the tension between mimesis and estrangement be resolved, but both mimesis and estrangement must be present in dystopian fiction. This inquiry began by seeking to resolve the tension between familiarity and alienation through a close reading of the techniques of canonical SF works (Dick, Le Guin, More) in order to see if they worked as a model for my own writing. The process required constant reflection: on the craft of writing in general; on the craft of world creation; on the process of character development; and on my interpretation of the ‘real world.’ My approach to the inquiry has resulted in an understanding of how these writers have combined techniques of realism with fantasy story-craft to render a plausible and unfamiliar world. An unexpected outcome of the writing was the discovery of the importance of experiences of masculinity to my reading habits and writing goals.

description: In this work, we investigate the feasibility of defining centrality in electron-ion collisions at the Electron-Ion Collider (EIC) by examining the correlation between the impact parameter and several observables, including total energy, total transverse momentum, and total number of particles. Using the BeAGLE Monte Carlo generator, we simulate e+Au and e+Ru collisions at different energies and analyze the correlation between the impact parameter and these observables across different kinematic regions. Our findings indicate that the correlation is weak in the central rapidity region but becomes stronger in the forward and far-forward rapidity regions. However, the correlation is not sufficiently robust to allow for precise centrality determination. We conclude that defining centrality in electron-ion collisions is more challenging than in ion-ion collisions, necessitating further studies to develop a robust centrality definition for the EIC.

description: Stochastic inflation, together with the $ΔN$ formalism, provides a powerful tool for estimating the large-scale behaviour of primordial fluctuations. In this work, we develop a numerical code to capture the non-perturbative statistics of these fluctuations and validate it to obtain the exponential non-Gaussian tail of the curvature perturbations. We present a numerical algorithm to compute the non-perturbative curvature power spectrum and apply it to both slow-roll (SR) and ultra-slow-roll (USR) single-field models of inflation. We accurately generate a non-perturbative scale-invariant power spectrum in the SR scenario. In the USR case, we obtain a peak in the power spectrum that, in the time-independent regime, aligns with the structure of its perturbative counterpart. Additionally, We underscore how the evolving nature of the super-Hubble perturbations in the USR model complicates the numerical computation of the non-perturbative spectrum.

An investigation of extraocular and intraocular wireless communication techniques on a retinal prosthesis system
Creators: name: Permana, Hans
Publisher: name: RMIT University
Year: 2024

description: Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are two genetic ocular diseases that cause gradual visual impairments which will eventually lead to blindness as a result of damage in the retina. In the cases of people suffering from RP and AMD, it has been found out that 95% of the photoreceptors are damaged, while interestingly majority of the bipolar and ganglion cells that are responsible for the nerve stimulation remain intact. This is where a retinal prosthesis system comes into the picture. Retinal prosthesis is a prosthetic device that is aimed to assume the functionality of the damaged photoreceptors and produce stimulations to the bipolar and ganglion cells for a visual perception. Typically, a retinal prosthesis system comprises of two major components: an image capturing unit and an array of microelectrode. While a lot of studies have been conducted on each major component, the development of the wireless link between the two components has been mostly overlooked. It is clear that the two components are not physically connected and a data exchange is required between the two. This thesis aims to bridge the knowledge gap in this area by addressing the following research questions: “What is the most suitable frequency band for a wireless link in a retinal prosthesis system?” and “What kind of antenna would generate the most optimal performance under the constraints introduced by a retinal prosthesis system?”
Collecting sensitive data during the Covid-19 pandemic: Lessons learned from the COBHAM study (Developing and delivering targeted SARS-CoV-2 (COVID-19) health interventions to Black, Asian and Minority Ethnic (BAME) communities living in the UK)
Creators: name: Sutton, Katie

description: Background: The COBHAM study involved the production of a culturally appropriate intervention to provide information on protective behaviours for people from Black and Asian populations. The intervention comprises an e-leaflet and a 3.5-minute film disseminated via a link in a text message sent from GP Practices. We conducted a preliminary evaluation of this intervention to explore how people from the relevant communities understand and interpret the intervention’s messages. Aim: To share our experiences of collecting sensitive qualitative data during the Covid-19 pandemic through entirely remote means. The aim being to convey lessons learned about navigating discussions on contentious issues with participants who have strongly held beliefs. Methods:  Potential participants were highlighted through an online survey, which asked for their phone number should they be happy to be contacted for an interview. A member of the research team then contacted potential participants to discuss recruitment to the trial. If in agreement, Microsoft Teams meetings were arranged. Information sheets and consent forms were sent via email. Consent was video-recorded at the start of the interview by asking participants to read and agree to the statements in the consent form. Results:  Collecting data from people specifically related to a protected characteristic (in this case ethnicity) on potentially sensitive issues (such as protective behaviours relating to covid transmission) required a high level of sensitivity and self-awareness, which was fully integrated into data collection planning. The rapid expansion of using video-conferencing software such as Microsoft Teams meant that people were generally familiar with their use. Conducting the interviews remotely facilitated a comfortable and safe forum for discussion.

description: Recent years have seen a great improvement in the computation of $CP$-conserving and $CP$-violating equilibration rates for leptogenesis. These are relevant for the relativistic regime of the sterile Majorana fermions and the dynamics of the Standard Model particles acting as spectator processes. In order to probe the regime of large $({\cal O}(10^2))$ washout parameters, we add $ΔL = 2$ washout processes, which we derive in the CTP-formalism. To demonstrate their significance, we apply state-of-the-art computational techniques to a simple yet well-motivated phenomenological scenario: unflavored leptogenesis in a hierarchical type-I seesaw model. We then perform a parameter scan of the final baryon asymmetry and find a constraint $m_\text{lightest} \lesssim 0.15 \, \text{eV}$ on the absolute neutrino mass scale, which is slightly less stringent than previously reported bounds obtained without the aforementioned improvements. The relaxation of the bounds is mainly due to partially equilibrated spectator fields, which protect part of the asymmetry from washout and lead to larger final asymmetries. While this might seem like a minor correction, the actual dynamics of the fields is substantially altered by these effects. Even though we focused on a particularly simple scenario for leptogenesis, the methods employed here can and should be extended to other models, thus giving us a more accurate picture of the different leptogenesis scenarios.

description: The UK government has introduced legislation for a suite of drugs known to cause impairment to help combat driving under the influence of drugs (DUID). The current preliminary tests have limitations, which has pressed for an improvement of screening methods for on-site analysis. Ambient ionisation techniques and their coupling to low-cost miniaturised mass spectrometers have demonstrated promise for routine in-situ analyses. Associated advantages include minimum sample preparation, and rapid data acquisition in real-time. Preliminary experiments evaluated the use of atmospheric solids analysis probe (ASAP-) and thermal desorption (TD-) techniques in conjunction with a Waters QDa; which were assessed for their applicability to identify a small number of medicinal drugs in synthetic saliva and plasma, with the intention to support DUID incidents. Calibration standards were prepared in methanol, synthetic saliva and crashed plasma. Methanol and synthetic saliva were spiked directly with the drug, whilst crashed plasma was dried under nitrogen before being reconstituted with the corresponding concentration of drug in methanol. Samples were introduced into the ASAP- and TD-QDa by capillary tubes and PTFE-fibreglass coated swabs, respectively. Infinite dilutions were analysed in each matrix to estimate the limit of detection (LOD) for each drug. Variable cone voltages generated analyte-specific fragment ions and introduced a degree of specificity not normally associated with this type of mass spectrometer. High selectivity was observed also. Greater sensitivity was demonstrated by ASAP-QDa (LODs <1000 ng mL-1) compared to the TD-QDa (LODs >1000 ng mL-1). An unmatched internal standard (IS) improved the linearity and standard error at each concentration of the calibration curve, as a matched IS shared fragment ions with two of the drugs present in the multi-analyte solution. Plasma analysed by ASAP-QDa yielded the greatest results at the tested concentration range. Overall, ASAP-QDa demonstrated greater promise for use as an in-situ screening method.
Self-portraiture and future: an examination of a photographer's creative identity

description: “Self-portraiture and future: an examination of a photographer’s identity” is a study of the genre of self-portraiture as a mode of creative reflective practice within the field of photography.

This thesis aligns theories of photography, art, art therapy and psychology to constitute a multidimensional dialogue around representation, imagination and transformation – as it relates to self-portraiture as a mode of creative reflective practice.

The thesis locates the necessary definitions for the genre of self-portraiture within art history and criticism. It reflects on the theories of representation that enable a study of meaning for photographic self-portraits from the point of view of reception. The thesis also refers to literature that advances the value of the practice of self-portraiture for the photographer, from the point of view of production.

The thesis posits that therapeutic photography can be considered a framework of practice, by establishing self-knowledge as essential in the development of one’s creative identity. This assertion is supported by a theory of the performative, whereby photographer acquires a triple role (author, subject and spectator of himself), thus dynamically exchanging between creating, being and looking. This complete experience of the photographic medium is said to have transformative potential as it nurtures a process of gaining awareness of how one creates technically and conceptually.

This character of transformative learning is further explored by developing photographic self-portraits that seek to develop the author’s visions of the future as intentional outcomes of creative practice. In order to achieve this, the author tentatively adopts a Jungian approach to her practice of self-portraiture; that is, the photographer is provided with a methodology that allows visions of future to emerge. By interacting with these visions on a mental level and through further establishing a photographic dialogue with the symbologies and emotions perceived in them through self-portraiture, the photographer reflects on her creative practice within a broader context of reflexive self-portraiture.

The researcher/photographer’s outcome asserts that self-portraiture as reflective practice, is a model of creative inquiry that should not be overlooked in the education of a photographer. It provides the photographer with tools that nurture the creative self through a spontaneous and personal process of experiencing the photographic medium.

The outcome implies that a reflective practice of self-portraiture focused on imagination is a valuable method of assessing the present and past, freeing one up to reclaim a desired future, which is a powerful tool that can promote transformation in our society.

description: This paper introduces a novel abstraction-based framework for controller synthesis of nonlinear discrete-time stochastic systems. The focus is on probabilistic reach-avoid specifications. The framework is based on abstracting a stochastic system into a new class of robust Markov models, called orthogonally decoupled Interval Markov Decision Processes (odIMDPs). Specifically, an odIMDPs is a class of robust Markov processes, where the transition probabilities between each pair of states are uncertain and have the product form. We show that such a specific form in the transition probabilities allows one to build compositional abstractions of stochastic systems that, for each state, are only required to store the marginal probability bounds of the original system. This leads to improved memory complexity for our approach compared to commonly employed abstraction-based approaches. Furthermore, we show that an optimal control strategy for a odIMDPs can be computed by solving a set of linear problems. When the resulting strategy is mapped back to the original system, it is guaranteed to lead to reduced conservatism compared to existing approaches. To test our theoretical framework, we perform an extensive empirical comparison of our methods against Interval Markov Decision Process- and Markov Decision Process-based approaches on various benchmarks including 7D systems. Our empirical analysis shows that our approach substantially outperforms state-of-the-art approaches in terms of both memory requirements and the conservatism of the results.
