description: Differential measurements of Higgs boson production in the $τ$-lepton-pair decay channel are presented in the gluon fusion, vector-boson fusion (VBF), $VH$ and $t\bar{t}H$ associated production modes, with particular focus on the VBF production mode. The data used to perform the measurements correspond to 140 fb$^{-1}$ of proton-proton collisions collected by the ATLAS experiment at the LHC. Two methods are used to perform the measurements: the Simplified Template Cross-Section (STXS) approach and an Unfolded Fiducial Differential measurement considering only the VBF phase space. For the STXS measurement, events are categorized by their production mode and kinematic properties such as the Higgs boson's transverse momentum ($p^{\text{H}}_\text{T}$), the number of jets produced in association with the Higgs boson, or the invariant mass of the two leading jets ($m_{jj}$). For the VBF production mode, the ratio of the measured cross-section to the Standard Model prediction for $m_{jj}>1.5$ TeV and $p^{\text{H}}_\text{T}>200$ GeV ($p^{\text{H}}_\text{T}<200$ GeV) is ${1.29}^{+0.39}_{-0.34}$ (${0.12}^{+0.34}_{-0.33}$). This is the first VBF measurement for the higher-$p^{\text{H}}_\text{T}$ criteria, and the most precise for the lower-$p^{\text{H}}_\text{T}$ criteria. The fiducial cross-section measurements, which only consider the kinematic properties of the event, are performed as functions of variables characterizing the VBF topology, such as the signed $Δϕ_{jj}$ between the two leading jets. The measurements have a precision of 30%-50% and agree well with the Standard Model predictions. These results are interpreted in the SMEFT framework, and place the strongest constraints to date on the CP-odd Wilson coefficient $c_{H\tilde{W}}$.

Biomonitoring of trace metals in the Saigon River
Creators: name: Nguyen, Ngoc
Publisher: name: RMIT University
Year: 2024

description: This study investigated trace essential metals (Cu, Zn and Cr) and non-essential metals (Pb, Cd and Hg) in water, sediment and tissues of water spinach, snake head fish and swamp eel from the Saigon River. Sampling was conducted from January to December 2004 at three sites. Three water and sediment samples, edible parts of twenty water spinach (Ipomea aquatica) samples (leaves and stems), twenty snake head fish (Channa striata) and twenty swamp eels (Monopterus albus) were collected at each site. Water, sediment and biota tissues were analysed for Cu, Zn, Cr, Pb, Cd and Hg following the method of USEPA, AOAC and NFTA. Results showed that Cu, Zn, Cr, Cd and Hg in water from the river was not higher than the maximum permitted level for protection of aquatic life by the national standards while the average Cu concentration in sediment was found to be close to the Effects range- low value and within the slightly polluted range (25- 50 mcg.g-1 dry weight). The results also showed that the river sediment was considered to be contaminated by Zn and Hg in comparison with contaminated sites in Australia and in Thailand. In water spinach, no Cu deficiency was found but Zn was accumulated. No accumulation of Cr, Cd and Hg was revealed but Pb was detectable. The results indicated that snake head and eel may have Cu deficiencies. Pb and Hg were found to be bioaccumulated in the muscle of snake head and eel at some sites on some occasions, but the levels were small. The results showed that metal in sediment liver of snake head muscle of snake head and eel water. The metals in water spinach decreased in the order Zn Cu Cr Pb Cd and Hg; in snake head the metal concentrations decreased in the order Zn Cu Cr PbHgCd and in eel as Zn Cu Cr PbCd and Hg. The ANOVA test showed no significant relationship between metals in the water and sediment and biota. Therefore it was concluded that the metals in the selected biota samples did not reflect the metals in the environment. The essential metals Cu, Zn and Cr were found to decrease at the end of the dry season and then increase at the end of the rainy season. The seasonal variations of metals in the river and biota maybe a result of the change of temperature in the area and the need for essential metals in the reproduction of fish. The results of this study clearly demonstrates that water spinach, snake head fish and swamp eel are not potential bio-indicators for metals in the Saigon River since they did not reflect concentrations of metals in their environment. It was also concluded based on consumption rates that water spinach, snake headfish and eel from the Saigon River do not present any potential health risk to consumers. However, attention should be paid to controlling the load of pollutants entering the river to avoid such risks and future problems.

description: A self-consistent gravitational quantum field theory, with gravitational force treated on the same footing as the other three fundamental interactions, was established recently. The gravidynamics predicted by such a theory could lead to important implications, and the comparisons with experimental results may provide us opportunities to test such new approach of gravity based on the framework of the quantum field theory of gauge interactions. In this work, we start with the effective field equation of the gravitational quantum field theory, and then solve the perturbative gravigauge field order by order up to the 1st post-Newtonian level under the assumption of a simplified energy-momentum tensor of perfect fluids. Having the constraints on the related post-Newtonian parameters from the most up-to-date observational data, the new bound on the combined coupling in the gravitational quantum field theory $|γ_G(α_G-α_W/2)|\leq (2.4\pm30)\times10^{-6} $ is obtained. Under such bound, we found that the new gravitational quantum field theory successfully passed and found no conflict with the contemporary keynote Solar system experiments of gravity.

description: We study conformal field theories at finite temperature in the presence of a temporal conformal line defect, wrapping the thermal circle, akin to a Polyakov loop in gauge theories. Although several symmetries of the conformal group are broken, the model can still be highly constrained from its features at zero-temperature. In this work we show that the defect and bulk one and two-point correlators can be written as functions of zero-temperature data and thermal one-point functions (defect and bulk). The defect one-point functions are new data and they are induced by thermal effects of the bulk. For this new set of data we derive novel sum rules and establish a bootstrap problem for the thermal defect one-point functions from the KMS condition. We also comment on the behaviour of operators with large scaling dimensions. Additionally, we relate the free energy and entropy density to the OPE data through the one-point function of the stress-energy tensor. Our formalism is validated through analytical computations in generalized free scalar field theory, and we present new predictions for the O(N) model with a magnetic impurity in the $\varepsilon$-expansion and the large N limit.

One dollar news: user needs and willingness to pay for digital news content
Creators: name: Hermansson, Gabriele
Publisher: name: RMIT University
Year: 2024

description: What is most important to online newspaper consumers and what will encourage them to not just read online news but actually pay for it is the key question investigated in this research. It looked at the changing user environment and the technological and cultural factors shaping it. I also examined the changing media landscape and how media organisations are dealing with changes in the behaviour of their readers. The main findings of this study are based on large scale user research of an Australian population. The research was aimed at finding out what factors encourage readership and potential willingness to pay for online news content. In addition to this, the study also looked at what monetary amount users are willing to pay for online news content.

The research was primarily quantitative in nature, utilising an online questionnaire. However, it also had a small component of qualitative research which collected users’ views on media organisations and news consumption. A case study of The Age, one of the largest Australian newspapers, was also carried out and included a number of interviews with business stakeholders to get their views of the current online media environment.

Whilst most anecdotal evidence suggests that users oppose to paying for news content online, this study suggests that this is not the case and that majority of people are willing to pay. What are they willing to pay? It seems like the golden number is around one dollar per month. A number of factors that influence user willingness to pay are also identified, together with suggestions of how media companies can use these factors to increase online news readership and revenue and establish a sound business model.

description: Die Verwaltung von Publikationsgebühren stellen viele Hochschulen und Forschungseinrichtungen vor großen Herausforderungen. Durch die deutliche Zunahme von Publikationen, die im Bereich Gold Open Access über Article Processing Charges finanziert werden, besteht die Notwendigkeit eines Systems, um diese zu organisieren. Neben der reinen Verwaltung der Gebühren sollte ein weiteres Ziel auch in der Erhöhung der Sichtbarkeit sowohl der Publikation als auch der Forschung an der eigenen Einrichtungen bestehen. Es ist daher naheliegend, dass insbesondere die Publikationen für die größtenteils nicht unbeträchtliche Mittel aufgewendet werden auch an der Institution selbst nachgewiesen und zugänglich gemacht werden. Letzteres geschieht i. d. R. über das institutionelle Repositorium. In einigen Fällen (wie z.B. bei den JOIN²-Projektpartnern) stellen diese Repositorien gleichzeitig die für das Berichtswesen maßgebliche Publikationsdatenbank oder Hochschulbibliographie dar. Da diese Systeme bereits bibliographische Daten auf Artikelebene präzise abbilden, liegt es nahe, auch die Gebührenzahlungen direkt dort aufzunehmen. Dies erspart Doppelerfassungen, verhindert Inkonsistenzen und verbessert die Vollständigkeit. Gleichzeitig ermöglicht der Einsatz von Repositoriumssoftware die Nachnutzung der Daten über standardisierte Schnittstellen. So können via standardisierten Schnittstellen (z. B. OAI-PMH) Publikationsgebühren offen bereit gestellt werden und beispielsweise von OpenAPC automatisiert und stets aktuell abgeholt werden. Dies kann zu einer Verbesserung der Markttransparenz beitragen. Zu diesen Schlüssen kamen etwa zeitgleich die Universtitätsbibliothek Regensburg und das JOIN² Projekt. Wir stellen die jeweiligen Lösungen basierend auf EPrints in Regensburg und INVENIO für JOIN² vor und beschreiben die automatisierte Datenlieferung an OpenAPC.

description: Obtaining microscopic structure-property relationships for grain boundaries are challenging because of the complex atomic structures that underlie their behavior. This has led to recent efforts to obtain these relationships with machine learning, but representing a grain boundary structure in a manner suitable for machine learning is not a trivial task. There are three key steps common to property prediction in grain boundaries and other variable-sized atom clustered structures. These are: (1) describe the atomic structure as a feature matrix, (2) transform the variable-sized feature matrices of different structures to a fixed length common to all structures, and (3) apply machine learning to predict properties from the transformed feature matrices. We examine these feature engineering steps to understand how they impact the accuracy of grain boundary energy predictions. A database of over 7000 grain boundaries serves to evaluate the different feature engineering combinations. We also examine how these combination of engineered features provide interpretability, or the ability to extract insightful physics from the obtained structure-property relationships.

Business planning by small owner managed enterprises in the Victorian forestry sector
Creators: name: Shepherd, Peter
Publisher: name: RMIT University
Year: 2024

description: Planning by owner-managers of small business has not received the attention from researchers a sector of such importance deserves. Using the forestry sector in Victoria as a sample, an investigation into the background and the planning undertaken by the owner-managers of small businesses was designed and implemented. The people consulted by the owner-manager as part of the planning process were identified as well as the topics discussed. A range of approaches to planning were identified and grouped into non-planners, partial planners and formal planners.

The sample was divided into Consultants and Contractors based on the type of work undertaken and the equipment used. Further sub-sets were identified. Contractors were split into Labour Intensive Contractors and Capital Intensive Contractors and the Consultants were also divided by age into "full time" and "later years" sub-sets. These data splits enabled significant insights into the planning of owner-managers.

Hindrances, hurdles and triggers to planning were identified. Informal planning appears to be the normal behaviour for much of the sample until a strong planning trigger overcomes the hurdles and hindrances and leads the owner-manager to engage more conventional planning activities. The owner-manager usually reverts to informal planning once the planning trigger issue is resolved.

Various relationships linking business characteristics, owner-manager demographic details and planning characteristics are explored to reveal some significant correlations that help explain results and can be used to guide professional development programs designed to increase the level of planning undertaken by owner-managers.

Regression analysis was used to show that relationships exist between the perceived value of planning by the owner-manager, level of computer literacy, level of literacy, the effort put into planning and the amount of planning undertaken. Insights into the business operations and management style of the managers interviewed would suggest the low level of planning undertaken will not be increased by just increasing the level of computer literacy and literacy in isolation.

The research reported here contributes to the understanding of planning approaches taken by owner-managers operating similar businesses to those sampled. The relationships between demographic details, organisation characteristics and planning activity provides an insight into the management philosophy and approach that can be used to assist with the design of management capacity building programs within the industry and as a foundation for further investigation.

description: We study a large family of generalized class groups of imaginary quadratic orders $O$ and prove that they act freely and (essentially) transitively on the set of primitively $O$-oriented elliptic curves over a field $k$ (assuming this set is non-empty) equipped with appropriate level structure. This extends, in several ways, a recent observation due to Galbraith, Perrin and Voloch for the ray class group. We show that this leads to a reinterpretation of the action of the class group of a suborder $O' \subseteq O$ on the set of $O'$-oriented elliptic curves, discuss several other examples, and briefly comment on the hardness of the corresponding vectorization problems.

Determining the influence of population variation on compliance with radiofrequency exposure limits
Creators: name: Sauren, Maia
Publisher: name: RMIT University
Year: 2024

description: How best to model humans for accurate SAR estimates remains an open question. Much work has been done over the years, attempting to quantify which and how various anatomic parameters such as tissue morphology, size, dielectric properties and relative location, affect energy absorption; and how to incorporate those parameters into models that provide conservative SAR estimates protecting all individuals. Since the available computational models are either highly complex realistic models or simple single tissue models, this issue is not easily explored, since the identified parameters are not easily varied within the models.

Attempts have been made in this thesis to overcome these limitations by creating a unique alternative model of the human head termed Geometry Head, incorporating a reduced set of tissues in a semi-homogeneous, simplified geometry for which the key parameters may be varied parametrically. Data was gathered from literature regarding what variations exist in human populations for tissue parameters, and used to populate the model. The computational model was validated using simplified physical models of human heads, custom made for this purpose. The Geometry Head model was used to systematically test what relationships exist between several anatomic variations in adult humans and consequent energy absorption due to RF exposure at a single frequency of 900 MHz, namely: cranial thickness; skin thickness; head size; and dielectric properties of tissues.

Overall, results suggest that SAR predictions could not have been anticipated using a priori reasoning, as location and magnitude of SAR maxima were seen to alter in unexpected and irregular ways with variations in tissue parameters. A compromise model like the one proposed here, which provides a point of diminishing returns between the high complexity of the multi-tissue models and the single-tissue homogeneous model, allows increased granularity for determination of SAR maxima in sensitive tissues.

Results of this work provide some inroads into establishing the level of complexity necessary for simulating human heads for radiofrequency exposure compliance calculations. Relationships between magnitude and location of regions of high SAR in the head and variables listed above have been quantified and qualified in this thesis.

The model proposed here is available for public use upon request. It can easily be amended to incorporate more or fewer tissues with varying levels of complexity; augmented to better resemble anatomy of children's heads; or used in its current state to further explore relationships between anatomic variations and absorption at the same frequency used here, or other RF frequencies.
The development of the Australian jazz real book
Creators: name: Nikolsky, Timothy
Publisher: name: RMIT University
Year: 2024

description: This study outlines a research project, which involved developing an Australian Jazz Real Book (AJRB). The research question guiding this study is: How is an Australian Jazz Real Book developed? A mixed methods approach was used in responding to the research question and incorporates survey, Real Book analysis and key informant interviews to create an insider-led work-based research project. Data was obtained through "a survey and Real Book analysis; from this a draft AJRB was produced. I embarked on a composition collection process, " accepting submissions from composers and attempting to locate compositions that were identified in the survey. The draft AJRB was used for comment and criticism by key informants in a series of interviews. Key Informants of education, performance, curriculum development and Australian jazz history were identified to represent a wide cross-section of the Australian jazz community. These people have 'insider' knowledge of the history and development of Australian jazz. . This study involved the development of the Australian Jazz Real Book. This research is important, as the AJRB has the potential to be a culturally and educationally significant resource as well as a useful tool for practicing musicians and educators in Australia. The AJRB is a resource, particularly relevant in tertiary music education communities. With its availability, it provides curriculum designers the opportunity to integrate previously unavailable Australian jazz. The AJRB was developed according to the results gained from the web survey. Key informant interviews provided greater insights and detail that were refined into the draft AJRB. Whilst this study did not encompass the implementation of the AJRB, its development has gone a long way towards addressing the aims of making Australian jazz compositions available, encouraging greater awareness of Australian jazz, and developing a useful resource for practicing and performing musicians.

description: Moiré heterostructures consisting of transition metal dichalcogenide (TMD) hetero- and homobilayers have emerged as a promising material platform to study correlated electronic states. Optical signatures of strong correlations in the form of Mott-Wigner states and fractional Chern insulators have already been observed in TMD monolayers and their twisted bilayers. In this work, we use a moiré substrate containing a twisted hexagonal boron nitride (h-BN) interface to externally generate a superlattice potential for the TMD layer: the periodic structure of ferroelectric domains in h-BN effects a purely electrostatic potential for charge carriers. We find direct evidence for the induced moiré potential in the emergence of new excitonic resonances at integer fillings, and our observation of an enhancement of the trion binding energy by $\simeq$ 3 meV. A theoretical model for exciton-electron interactions allows us to directly determine the moiré potential modulation of 30$\pm$5 meV from the measured trion binding energy shift. We obtain direct evidence for charge order linked to electronic Mott-Wigner states at filling factors $ν$ = 1/3 and $ν$ = 2/3 through the associated exciton Umklapp resonances.

The city as a curated space: a study of the public urban visual arts in central Sydney and central Melbourne, Australia
Creators: name: Hulbert, Tammy
Publisher: name: RMIT University
Year: 2024

description: This study frames the city as a site for artistic activity and presents a distributed model of exhibition in urban spaces. The research investigates the configuration of the visual arts in public spaces as an alternative to the visual arts institutional model of gallery based exhibitions. Since the 1990s there has been an increase in public urban visual arts activity in Australian city centres. This has occurred for a number of reasons: artists are increasingly interested in experimenting with new ways of interpreting and activating the public sphere; local governments are seeing the benefits of engaging communities through public art practices and city planners are showing an increased interest in the role of artists and artwork in urban regeneration. This research investigates the view that the city can be configured as a curated space, in terms of an ecosystem where interdependent agents navigate complexity to work within this system. The research of this proposition is undertaken via two Australian case studies of central Melbourne and Sydney. It examines the function of curation as applied to those urban locations by focusing on recent public art activity in inner urban laneway spaces. Influenced by Michel Foucault’s (1926-1984) methodology of archaeology and genealogy, discourses of the curation of the city have been identified in the comparative case studies. These discourses were constructed to present a critical history of the present and investigates the impact of local practices upon the subsequent outcomes in each of the cities. A further three minor international case studies of San Francisco, USA, Shanghai, China and Şile, Istanbul, give an international perspective to the conceptual framework of the research. An analysis of the major and minor case studies informs the development of a model framework for the city as a curated space, and advises how the curated city could be considered by key agents working within this system. This research offers new knowledge in two forms: 1) A conceptual outcome – the curated city is understood as an interdependent ecosystem; 2) A practical outcome – a new model framework that provides key actions for the cultural, creative and economic enhancement of the ecosystem.
title: Novel optimisation methods for data assimilation
Creators: name: Kaouri, Maha Hussein
Publisher: name: University of Reading
Year: 2021

description: Data assimilation (DA) is a technique used to estimate the state of a dynamical system. In DA, a prior estimate (background state) is combined with observations to estimate the initial state of a dynamical system over a given time-window. This estimate is known as the ‘analysis’ in DA. In variational data assimilation (VarDA), the DA problem is formulated as a nonlinear least-squares problem, usually solved using a variant of the classical Gauss�Newton (GN) optimisation method known as the incremental method. In the incremental method, the iterative minimisation of the nonlinear objective function and the linearised subproblem are referred to as the ‘outer loop’ and the ‘inner loop’ respectively. Within this thesis, we show how the convergence of GN can be improved through the use of safeguards that, unlike GN, guarantee convergence to the analysis from an arbitrary back�ground state, while considering the limited time and cost available in DA. In particular, we consider GN equipped with line search (LS) and GN equipped with quadratic regularisation (REG), both of which achieve global convergence by guaranteeing a reduction in the VarDA objective function at each outer loop iteration. We prove global convergence of LS and REG and use idealised numerical experiments to show that these methods are able to improve the current estimate of the DA analysis even if the initial estimate of the solution is poor and a long assimilation time-window is used to include more observations. Furthermore, when GN performs poorly, a suitable choice of the initial regularisation parameter is critical in enhancing the performance of the REG method. We study the interaction between the REG parameter and the VarDA inner loop problem and use numerical experiments to show that choosing the initial REG parameter according to components of the VarDA problem results in REG locating a more accurate DA analysis than that obtained by GN, LS or the standard REG method. Various simplifications are made to solve the variational problem within the time and com�putational cost available in practice. One of these simplifications is the use of a reduced resolution spatial grid for use within the inner loop. It is known that the accuracy with which the inner loop is solved affects the convergence of the outer loop. The condition num�ber of the Hessian is a measure of the sensitivity of the solution of the inner loop problem to perturbations and also influences the speed of convergence of the VarDA inner loop minimi�sations. We derive an upper bound on the condition number of the preconditioned VarDA Hessian that accounts for different inner loop resolutions of the incremental method.

Developing a spatial approach to support local flood-risk-based land use planning
Creators: name: Pourali, Hossain
Publisher: name: RMIT University
Year: 2024

description: Flood-risk-based land use planning is largely a local government responsibility in Australia. In my research I sought to develop a new spatial approach to improve the implementation of flood-risk-based land use planning that can be used by local governments. In Australia, strategies for floodplain management to reduce and control flooding are best implemented at the land use planning stage. Flood-risk-based land use planning results in sustainable land management activities, including floodplain management. Flood-risk-based land use planning is largely dependent on flood behaviour across the land development areas, which can be documented in the form of planning zones that warn land use planners about the flood-threatened area. However, these are often out-dated so do not reflect the influence of recent land use changes. This is particularly for peri-urban areas (largely focus on riverine floods) and expensive to update. Developing a new approach based on geospatial science facilitates the implementation of flood-risk-based land use planning process and can provide a better approach for local governments in terms of cost, accuracy and ease of updating. To develop a new approach, a clear understanding of responsibility for flood-risk-based land use planning, the workflow processes in the authority responsible for such planning, the quality of existing database and how new data sources and the technology (e.g., LiDAR data and crowd source data) that can be used for flood-risk-based land use planning, is essential. The research involved a case study to document the process of flood-risk-based land use planning processes used by a Victorian council, an assessment of flood-relevant database completeness and accuracy, determination of missing datasets and information in the council’s flood-relevant GIS database, and development of methods based on GIS-embedded hydrological models to generate those datasets.

description: Pedestrian crowds encompass a complex interplay of intentional movements aimed at reaching specific destinations, fluctuations due to personal and interpersonal variability, and interactions with each other and the environment. Previous work showed the effectiveness of Langevin-like equations in capturing the statistical properties of pedestrian dynamics in simple settings, such as almost straight trajectories. However, modeling more complex dynamics, e.g. when multiple routes and origin-destinations are involved, remains a significant challenge. In this work, we introduce a novel and generic framework to describe the dynamics of pedestrians in any geometric setting, significantly extending previous works. Our model is based on Langevin dynamics with two timescales. The fast timescale corresponds to the stochastic fluctuations present when a pedestrian is walking. The slow timescale is associated with the dynamics that a pedestrian plans to follow, thus a smoother path. Employing a data-driven approach inspired by statistical field theories, we learn the complex potentials directly from the data, namely a high-statistics database of real-life pedestrian trajectories. This approach makes the model generic as the potentials can be read from any trajectory data set and the underlying Langevin structure enables physics-based insights. We validate our model through a comprehensive statistical analysis, comparing simulated trajectories with actual pedestrian measurements across five complementary settings, including a real-life train platform scenario, underscoring its practical societal relevance. We show that our model effectively captures fluctuation statistics in pedestrian motion. Beyond providing fundamental insights and predictive capabilities in pedestrian dynamics, our model could be used to investigate generic active dynamics such as vehicular traffic and collective animal behavior.

Strong effects of thermally induced low-spin-to-high-spin crossover on transport properties of correlated metals

description: We use dynamical mean-field theory to study how electronic transport in multi-orbital metals is influenced by correlated (nominally) empty orbitals that are in proximity to the Fermi level. Specifically, we study 2 + 1 orbital and 3 + 2 orbital (i.e. t2g + eg ) models on a Bethe lattice with a crystal field that is set so that the higher lying orbitals are nearly empty at low temperatures but get a non-negligible occupancy at elevated temperature. The high temperature regime is characterized by thermal activation of carriers leading to higher magnetic response (i.e., thermally induced low-spin to high-spin transition) and substantial influence on resistivity, where one can distinguish two counteracting effects: increased scattering due to formation of high spin and increased scattering phase space on one hand, and additional parallel conduction channel on the other. The former effect is stronger and one may identify cases where resistivity increases by a factor of three at high temperatures even though the occupancy of the unoccupied band remains small (< 10%). We discuss implications of our findings for transport properties of correlated materials.

Microeconomic reform of the building and development process : the development and outcomes of building regulation reform in Australia 1990-2003
Creators: name: Wallace, Gabrielle
Publisher: name: RMIT University
Year: 2024

description: As a component of the regulatory structure controlling building construction and land development in Australia, the system of building regulation was reformed during a period of significant restructuring of the Australian economy. The microeconomic reforms aimed to find efficiencies in government and industry sectors, and with respect to the latter, facilitate the development of competitive trade structures across national and global markets. The research provides a critical narrative account of the development and outcomes of the microeconomic reform of building regulation between 1990 and 2003. The microeconomic reform process is examined in the context of the vastly differing approaches of two Australian states, Victoria and New South Wales, with respect to the national reform agenda which was initiated and led by the Commonwealth government in response to the increasing globalization of the national economy. An understanding of what happened and why and how the states differed with respect to the national reform agenda enabled the outcomes of the reforms to be examined for their impact upon government, industry and the community. The regulation of building construction is a constitutional responsibility of the state governments and has traditionally been controlled by local government. However, control is increasingly being centralized at the national level, in response to international pressures to adopt performance-based regulations, standards and governance systems that accord to neoliberal ideology. This has resulted in a reduction of state and local government involvement in certain building control functions with a commensurate increased role for the private sector; an increase in the complexity and quantity of regulatory instruments; a reduction in government accountability for the standard of building construction; the development of structures to facilitate competitive intranational and international trade in construction-related goods and services and a reduction in the quality and standard of buildings. The principal benefits of the reforms have accrued to industry and to government and the least benefits have accrued to the community/consumer.

description: Continued improvement of heat control in mesoscopic conductors brings novel tools for probing strongly correlated electron phenomena. Motivated by these advances, we comprehensively study transport due to a temperature bias in a quantum point contact device in the fractional quantum Hall regime. We compute the charge-current noise (so-called delta-$T$ noise), heat-current noise, and mixed noise and elucidate how these observables can be used to infer strongly correlated properties of the device. Our main focus is the extraction of so-called scaling dimensions of the tunneling anyonic quasiparticles, of critical importance to correctly infer their anyonic exchange statistics.

Creators: name: Pattanachoti, Ohm
Publisher: name: RMIT University
Year: 2024

description: This practice lead doctoral research project explores my spirituality and its relationship to Thai identity, Buddhist background and conversion to Christianity through a series of paintings. The project has two aims, one, to further develop my practice and style of painting, two, to answer the proposed research question, that addresses the knowledge and symbolism of Buddhist and Christian beliefs and the subsequent use of religious imagery within contemporary art practice. Themes investigated occurred through processes of painting, a considered use of narrative, the symbolism of colour, pictorial structure and content. This project will consider the progression of my work and artistic style through four bodies of work:

The series of Faith and Belief no. 1- 4
Searching for Self-awareness no. 1
Searching for self-awareness no. 2 - 3
Searching for self-awareness no. 4 - no. 6

Art works presented have contributed towards the development of the recent series Spiritual Identity which is comprised of two works: Spiritual Identity: Inner Land and Spiritual Identity: the overlay of memories 1 - 3, a series of works that are symbolic of the culmination of the exploration of my spiritual and cultural identity.
