description: According to the recast Renewable Energy Directive (RED II), member states (MS) of the European Union (EU) are supposed to take out assessments of barriers for and potential of renewable energy communities in their countries (RED II, Art. 22 Para. 3). The European legislator has not specified this provision, i.e. the content and form of these assessments has not been clarified (yet). It is only clear from the legal text that these assessments should be the basis of the “enabling framework” (RED II, Art. 22 Para. 4) that EU MS shall provide. The project aims at developing a template for the assessments. Moreover, a model assessment (only a rapid assessment, though) will be carried out for two countries – Germany and Poland. This checklist presents a short overview of issues that potential assessors of barriers and potential of renewable energy communities should take into consideration. Moreover, it refers to project deliverables which detail those issues.
title: A material point method to simulate macro-scale problems in mining
Creators: name: Basson, G
Publisher: name: University of Tasmania
Year: 2022

description: Seismic hazard poses a major risk to mines, and is one of the biggest deciding factors of the future of a mine. It is not only capable of taking lives, but also guides the resources required to extract the minerals. Numerical modelling is an important tool available to mining engineers, to help them manage seismic risk. Modelling allows engineers to study how the rock mass will respond to the ever changing rock mass conditions, since they cannot physically observe it. Fortunately, there are a plethora of modelling tools available to mining engineers to assist in this task. However, most of these tools are specialised and are suited to only address certain problems. This study is aimed at researching and developing a tool that miners can use to address a broad spectrum of problems, with the ultimate goal of better understanding seismicity. This thesis is based on the Material Point Method (MPM), a novel numerical approach that combines the best aspects of Lagrangian and Eulerian techniques. The attraction of the MPM over many other numerical strategies is that it does not require repeated remeshing of the underlying computational grid when large deformations occur. Furthermore, it is relatively simple to construct intricate models of large mining layouts. This study makes four major contributions to the MPM. First, a new computational background mesh is developed for the MPM such that it can be used to simulate models of large mining layouts. Second, a novel method is developed to extract seismic events from elasto-plastic regions in the model. These events are not simply points in space, as commonly assumed in other numerical modelling packages that is currently available to the mining industry, but it also contains size as well as a source mechanism that may accurately resemble real seismicity that occur around a mine. Third, a novel algorithm of the coupled MPM is proposed to handle problems of fluid- and solid mixtures in mediums with heterogeneous permeability. Fourth, a new method for handling fractures as well as fracture propagation is proposed. This is used to simulate hydraulic fracturing preconditioning in mining where a dense fracture network is created within a small volume of rock such that stress is redistributed away from the area and become less seismically hazardous. These additions to numerical modelling in mining allows for addressing a wide range of problems, all with the goal to have better control over mining-induced seismicity.

description: Nonperturbative methods play an important role in quantum many-body systems, especially in situations with an interplay of continuum and bound states and/or large coupling strengths between the constituents. Employing the Luttinger-Ward functional (LWF) we have computed the equation of state (EoS) of the quark-gluon plasma (QGP) using fully dressed selfconsistent 1- and 2-body propagators. We first give an alternative derivation of our previously reported results for resumming the ladder diagram series of the LWF using a "matrix log" technique which accounts for dynamically formed bound and resonant states. Two types of solutions were found in selfconsistent fits to lattice-QCD data for the EoS, heavy-quark free energy and quarkonium correlators: a strongly coupled scenario (SCS) with broad parton spectral functions and strong meson resonances near the transition temperature vs. a weakly coupled scenario (WCS) with well-defined parton quasiparticles and weak meson resonances. Here, we discuss how these solutions can be distinguished by analyzing the pertinent transport properties. We focus on the specific shear viscosity, $(4π)η/s$, and the heavy-quark diffusion coefficient, $(2πT) {\cal D}_s$, including its mass dependence. At low temperatures, in the SCS, they turn out to be a factor of 2 within their conjectured quantum lower bound, while they are a factor of 2-5 larger in the WCS. At higher temperatures, the transport parameters of the two scenarios approach each other. We propose the ratio $ (4πη/s)/(2πT {\cal D}_s )$ as a measure to distinguish the perturbative and strong-coupling limits of 5/2 and 1, respectively.

description: Human values such as freedom, fairness, and social responsibility, often remain unnoticed and unattended during software development. Ignoring values can lead to values violations in software that can result in financial losses, reputation damage, and widespread social and legal implications. This research aims to operationalize human values in software by identifying the need for research on values in Software Engineering and examining the impact of explicit considering human values during Requirements Engineering (RE) activities on software design. Further, this study proposes a framework that is capable of documenting and evaluating such impact from explicit considerations of human values in RE.
title: Development of synthetic immunological tools for Tasmanian devil research
Creators: name: De Luca, AJ
Publisher: name: University of Tasmania
Year: 2022

description: The Tasmanian devil (Sarcophilus harrisii) is the world’s largest extant carnivorous marsupial. The wild population of devils has been decimated by two transmissible cancers, collectively named Devil Facial Tumour Disease (DFTD). Transmissible cancers are exceedingly rare and only three are found in mammalian species. The occurrence of two of these transmissible cancers in a single species raises a number of questions about the devil’s immune system and the pathogenesis of these diseases. Understanding the Tasmanian devil immune system and how it responds to these transmissible tumours is imperative for the continued conservation of this species. This research may also provide insight into the tumour - host immune system relationship in other cancers including human disease. Development of immune checkpoint immunotherapies and cancer vaccines have provided more targeted cancer therapies that are safer for patients and are in many cases more effective than traditional chemotherapy or radiotherapy. The understanding of immune system function and disease pathogeneses enhances the development of safe, effective, and rational therapies for disease. One of the major problems facing the field of wild immunology is the reagent gap. This refers to the lack of research tools and reagents available that specifically and reliably bind to non-human, non-model species targets. While thousands of antibodies are commercially available that bind to rodent or human targets, there are less than 30 that bind to Tasmanian devil targets, many of which have had to be developed in-house or custom ordered and are not commercially available. The development of specific, affordable, and reliable research tools will allow investigation into DFT pathogenesis, development of therapies, and analysis of therapy efficacy to be faster, more reliable, and more reproducible. A digital database of hybridoma derived anti-Tasmanian devil checkpoint molecule antibody sequences was designed and will provide a resource for the development of several novel antibodies and other affinity reagents for use in DFTD research, diagnoses, and therapies. Producing synthetic affinity reagents from known sequences is faster and cheaper than conventional antibodies without compromising specificity or affinity. Devilisation of hybridoma derived antibodies involves hybridising the mouse derived variable regions with devil derived constant regions. Compared to mouse derived antibodies, devilised reagents are less immunogenic and more appropriate for functional immune research and eventually, therapeutic applications. This thesis presents a method of producing anti-PDL1 devilised recombinant antibodies using a mammalian cell-based protein expression system.

title: Challenges experienced by Australian forensic practitioners in international disaster victim identification operations
Creators: name: Adamovic, N
Publisher: name: University of Tasmania
Year: 2022

description: Disaster Victim Identification (DVI) is an important process in the aftermath of disasters. Australian forensic practitioners contribute to such processes internationally under difficult post-disaster circumstances. The aim of the study was to determine the main challenges experienced by forensic practitioners in overseas DVI operations. Twenty Australian forensic practitioners were interviewed. The participants included DNA analysts, fingerprint examiners, forensic odontologists, forensic pathologists, and mortuary technicians. Participants shared their experiences and perceptions of DVI processes across a broad range of events in which they had participated. Interview data were analysed using thematic analysis. Six main themes were identified: the working environment, project management, interpersonal interactions, personal challenges, social and political factors, and suggestions for improvement. Key findings highlighted the interrelated and overlapping nature of various challenges, and in particular, the importance of the work environment in international contexts. The thesis concludes with implications for practice arising from the findings, such as enhanced pre-disaster preparation and training across forensic disciplines and organisational contexts.

description: There have been extensive efforts in government, academia, and industry to anticipate, forecast, and mitigate cyber attacks. A common approach is time-series forecasting of cyber attacks based on data from network telescopes, honeypots, and automated intrusion detection/prevention systems. This research has uncovered key insights such as systematicity in cyber attacks. Here, we propose an alternate perspective of this problem by performing forecasting of attacks that are analyst-detected and -verified occurrences of malware. We call these instances of malware cyber event data. Specifically, our dataset was analyst-detected incidents from a large operational Computer Security Service Provider (CSSP) for the U.S. Department of Defense, which rarely relies only on automated systems. Our data set consists of weekly counts of cyber events over approximately seven years. Since all cyber events were validated by analysts, our dataset is unlikely to have false positives which are often endemic in other sources of data. Further, the higher-quality data could be used for a number for resource allocation, estimation of security resources, and the development of effective risk-management strategies. We used a Bayesian State Space Model for forecasting and found that events one week ahead could be predicted. To quantify bursts, we used a Markov model. Our findings of systematicity in analyst-detected cyber attacks are consistent with previous work using other sources. The advanced information provided by a forecast may help with threat awareness by providing a probable value and range for future cyber events one week ahead. Other potential applications for cyber event forecasting include proactive allocation of resources and capabilities for cyber defense (e.g., analyst staffing and sensor configuration) in CSSPs. Enhanced threat awareness may improve cybersecurity.

description: In two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), new electronic phenomena such as tunable band gaps and strongly bound excitons and trions emerge from strong many-body effects, beyond spin-orbit coupling- and lattice symmetry-induced spin and valley degrees of freedom. Combining single-layer (SL) TMDs with other 2D materials in van der Waals heterostructures offers an intriguing means of controlling the electronic properties through these many-body effects via engineered interlayer interactions. Here, we employ micro-focused angle-resolved photoemission spectroscopy (microARPES) and in-situ surface doping to manipulate the electronic structure of SL WS$_2$ on hexagonal boron nitride (WS$_2$/h-BN). Upon electron doping, we observe an unexpected giant renormalization of the SL WS$_2$ valence band (VB) spin-orbit splitting from 430~meV to 660~meV, together with a band gap reduction of at least 325~meV, attributed to the formation of trionic quasiparticles. These findings suggest that the electronic, spintronic and excitonic properties are widely tunable in 2D TMD/h-BN heterostructures, as these are intimately linked to the quasiparticle dynamics of the materials.

description: With digital privacy being one of society’s main concerns, this thesis focuses on designing privacy-preserving primitives to meet future quantum computer security demands. In particular, we focus on group and ring signatures, which allow to anonymously sign messages on behalf of a group. This thesis designs new post-quantum group and ring signatures based exclusively on symmetric primitives to provide post-quantum security, which leads to four major contributions: the design of three different fully dynamic group signatures and the development of a new generic construction for an ID-based ring signature. This thesis also demonstrates the importance of symmetric-based primitives to face the democratization of quantum computers.
Tunneling conductance in semiconductor-superconductor hybrid structures

description: We study the differential conductance for charge tunneling into a semiconductor wire--superconductor hybrid structure, which is actively investigated as a possible scheme for realizing topological superconductivity and Majorana zero modes. The calculations are done based on a tight-binding model of the heterostructure using both a Blonder-Tinkham-Klapwijk approach and a Keldysh non-equilibrium Green's function method. The dependence of various tunneling conductance features on the coupling strength between the semiconductor and the superconductor, the tunnel barrier height, and temperature is systematically investigated. We find that treating the parent superconductor as an active component of the system, rather than a passive source of Cooper pairs, has qualitative consequences regarding the low-energy behavior of the differential conductance. In particular, the presence of sub-gap states in the parent superconductor, due to disorder and finite magnetic fields, leads to characteristic particle-hole asymmetric features and to the breakdown of the quantization of the zero-bias peak associated with the presence of Majorana zero modes localized at the ends of the wire. The implications of these findings for the effort toward the realization of Majorana bound states with true non-Abelian properties are discussed.

description: Masures are generalizations of Bruhat-Tits buildings. They were introduced to study Kac-Moody groups over ultrametric fields, which generalize reductive groups over the same fields. If A and A are two apartments in a building, their intersection is convex (as a subset of the finite dimensional affine space A) and there exists an isomorphism from A to A fixing this intersection. We study this question for masures and prove that the analogous statement is true in some particular cases. We deduce a new axiomatic of masures, simpler than the one given by Rousseau.

description: There is a balancing act between quality and time as we move from autoregressive to non-autoregressive models. Autoregressive models are slower but produce better quality output compared to non-autoregressive models which are faster. Semi-autoregressive models provide the best of both worlds by decoding faster but at the expense of output quality. This thesis, therefore, explores the problem of text generation to improve generation across the three model families. It identifies and addresses various literature gaps such as ineffective decoding methods for autoregressive models, lack of length flexibility in autoregressive and non-autoregressive models, and inferior output quality by non-autoregressive models compared to autoregressive models.
Far Cry 5 – Refusing its Own Politics

description: Far Cry 5 (2018) gives the Far Cry series a well-deserved break from colonial and oriental tropes about the savage barbarians and the western saviour. The game delivers a rural, right-wing power fantasy that leans into MAGA and conspiracy discourse. It is Red Dawn (1984) for the modern American culture war and paints the conservative right as the heroes and the left as the villains. You play the role of a police deputy who must defend their home and their neighbours from The Project at Eden’s Gate cult, who takes over the county after a failed arrest of the cult’s leader. But this game review argues that it is a problematic game, which refuses to reflect and comment upon the political message it sends and the political landscape it places itself into.

description: In the Fock representation, we construct matrix product states (MPS) for one-dimensional gapped phases for $\mathbb{Z}_{p}$ parafermions. From the analysis of irreducibility of MPS, we classify all possible gapped phases of $\mathbb{Z}_{p}$ parafermions without extra symmetry other than $\mathbb{Z}%_{p}$ charge symmetry, including topological phases, spontaneous symmetry breaking phases and a trivial phase. For all phases, we find the irreducible forms of local matrices of MPS, which span different kinds of graded algebras. The topological phases are characterized by the non-trivial simple $\mathbb{Z}_{p}$ graded algebras with the characteristic graded centers, yielding the degeneracies of the full transfer matrix spectra uniquely. But the spontaneous symmetry breaking phases correspond to the trivial semisimple $\mathbb{Z}_{p/n}$ graded algebras, which can be further reduced to the trivial simple $\mathbb{Z}_{p/n}$ graded algebras, where $n$ is the divisor of $p$. So the present results deepen our understanding of topological phases in one dimension from the viewpoints of MPS.

description: We address the problem of reconstructing articulatory movements, given audio and/or phonetic labels. The scarce availability of multi-speaker articulatory data makes it difficult to learn a reconstruction that generalizes to new speakers and across datasets. We first consider the XRMB dataset where audio, articulatory measurements and phonetic transcriptions are available. We show that phonetic labels, used as input to deep recurrent neural networks that reconstruct articulatory features, are in general more helpful than acoustic features in both matched and mismatched training-testing conditions. In a second experiment, we test a novel approach that attempts to build articulatory features from prior articulatory information extracted from phonetic labels. Such approach recovers vocal tract movements directly from an acoustic-only dataset without using any articulatory measurement. Results show that articulatory features generated by this approach can correlate up to 0.59 Pearson product-moment correlation with measured articulatory features.

description: Geostationary satellites collect high-resolution weather data comprising a series of images which can be used to estimate wind speed and direction at different altitudes. The Derived Motion Winds (DMW) Algorithm is commonly used to process these data and estimate atmospheric winds by tracking features in images taken by the GOES-R series of the NOAA geostationary meteorological satellites. However, the wind estimates from the DMW Algorithm are sparse and do not come with uncertainty measures. This motivates us to statistically model wind motions as a spatial process drifting in time. We propose a covariance function that depends on spatial and temporal lags and a drift parameter to capture the wind speed and wind direction. We estimate the parameters by local maximum likelihood. Our method allows us to compute standard errors of the estimates, enabling spatial smoothing of the estimates using a Gaussian kernel weighted by the inverses of the estimated variances. We conduct extensive simulation studies to determine the situations where our method performs well. The proposed method is applied to the GOES-15 brightness temperature data over Colorado and reduces prediction error of brightness temperature compared to the DMW Algorithm.

description: This thesis explores the 'institutional life' of the Australian Centres of Excellence Programme. The study asks professional and research leads of the CoEs about their observations and experiences of ‘organising’ research programmes in relation to the university. Mapping their stories onto network models as ‘network narratives’ shows that CoEs can grow into a number of different forms of networks. The research finds the types of networks and co-leadership of the CoEs could influence information exchange and how effectively a coherent CoE forms. Stories of ‘odd’ encounters also suggest that the CoE is an emerging form in a complex system.

description: We establish necessary and sufficient conditions for a semigroup identity to hold in the monoid of $n\times n$ upper triangular tropical matrices, in terms of equivalence of certain tropical polynomials. This leads to an algorithm for checking whether such an identity holds, in time polynomial in the length of the identity and size of the alphabet. It also allows us to answer a question of Izhakian and Margolis, by showing that the identities which hold in the monoid of $2\times 2$ upper triangular tropical matrices are exactly the same as those which hold in the bicyclic monoid. Our results extend to a broader class of "chain structured tropical matrix semigroups"; we exhibit a faithful representation of the free monogenic inverse semigroup within such a semigroup, which leads also to a representation by $3\times 3$ upper triangular matrix semigroups, and a new proof of the fact that this semigroup satisfies the same identities as the bicyclic monoid.

Learning About Ourselves: Communicating, Connecting and Contemplating Trans Experience Through Play
Creators: name: Baird, Josephine
Publisher: name: gamevironments
Year: 2022

description: This article posits that intentional non-formal and informal educational game design can provide an opportunity for the safer exploration of, and learning about, (trans)gender subjectivities. Non-formal and informal learning has been shown to be a more accessible and safer proposition for marginalised communities who are often excluded from formal and recognised social institutions. Non-formal and informal learning is also a structurally appropriate approach for exploring counter-normative topics, including diversities of gender and sexualities. I will demonstrate how studies of game-based learning and edu-larp put these principles into practice through gameplay and framing activities which facilitate experiential and situated learning. I will argue that this approach is particularly useful for the simulation of the complex intersectional socio-cultural function of gender. I will conclude that an edu-larp design approach can provide the basis for intentional educational game design utilising principles of safer containers of play, emancipatory bleed, and transformative role-play to explore trans experience, for both trans- and cis-participants alike.

I argue that the process of designing fantasy character cultures, as part of the wider worldbuilding process, is in need of a major rethink if principles of anti-oppression are to be followed. The frequently problematic depictions of female characters, and the remediation of real-world cultures into fictional races, in fantasy games and other fantasy fiction, are explored in a close reading of the biggest name in fantasy computer gaming, World of Warcraft (2004). I then offer tools, techniques, and principles for practical worldbuilding of fictional cultures and religions that will both avoid the appropriative practices that are the mainstay of most worldbuilding, and create more original and compelling fictional settings. These techniques are derived from a combination of literature research into existing recommendations on anti-oppressive game design; conversations with working games artists and game designers; teaching methods derived from teaching practical worldbuilding and games narrative design on several courses at different universities; and my PhD thesis, the conclusions of which included suggestions as to a code of practice on ethical game design. A step-by-step worked example is included: a fictional culture that is verisimilitudinous without being clearly based on a specific real-world culture. This makes for an effective starting point for anti-oppressive worldbuilding, as well as tying in with principles of user-centric design: settings created in this manner come across as fresh and original, without the often problematic clichés of yet another remediation of Dungeons and Dragons (hereafter D&D) (1974) remediating Tolkien. These tools and techniques allow for the creation of fictional settings that are not only grounded in principles of anti-oppressive game design but also powerfully verisimilitudinous in a way that World of Warcraft, for example, is clearly not. Despite the gamer community’s frequently expressed fears of censorship by the social justice movement, this kind of approach to design would create better and more original art, freed from the conservative remediation-upon-remediation culture of conventional fantasy and science fiction game designs.

They Will Do Anything to Make You React: Deplatforming Racists from the Brazilian Gaming Community
Creators: name: Caetano, Mayara Araujo

description: This article discusses the deplatforming of a racist content creator and streamer from the Brazilian gaming community. It raises questions about the extent of success of deplatforming when platforms are also structurally oppressive. The case being discussed started after racist harassment during #BlackLivesMatter mobilisation after Floyd; and was led by players, creators, and allies aiming for an anti-racist gaming environment in Brazil. Narrative interviews (Rosenthal 2018) were conducted with the victims and articulators to understand the construction of this coalition. Their testimonies, combined with social media materials collected during and after the event, were analysed using the intersectional roulette (Carrera 2021) and show how platform structures, companies, and Institutions present significant obstacles in enforcing their Community Guidelines, Terms of Use, reporting system, and compliance with the Law. Nevertheless, it is still a noteworthy case of social justice, representing how the strategic use of technologies can benefit collective engagement.

description: Random walks are ubiquitous in the sciences, and they are interesting from both theoretical and practical perspectives. They are one of the most fundamental types of stochastic processes; can be used to model numerous phenomena, including diffusion, interactions, and opinions among humans and animals; and can be used to extract information about important entities or dense groups of entities in a network. Random walks have been studied for many decades on both regular lattices and (especially in the last couple of decades) on networks with a variety of structures. In the present article, we survey the theory and applications of random walks on networks, restricting ourselves to simple cases of single and non-adaptive random walkers. We distinguish three main types of random walks: discrete-time random walks, node-centric continuous-time random walks, and edge-centric continuous-time random walks. We first briefly survey random walks on a line, and then we consider random walks on various types of networks. We extensively discuss applications of random walks, including ranking of nodes (e.g., PageRank), community detection, respondent-driven sampling, and opinion models such as voter models.

description: We investigated excitonic absorptions in GaAs/AlAs/GaAs single barrier heterostructure using both photocapacitance and photocurrent spectroscopies at room temperature. Photocapacitance spectra show well defined resonance peak of indirect excitons formed around the Gamma-AlAs barrier. Unlike DC-photocurrent spectra, frequency dependent photocapacitance spectra interestingly red shift, sharpen up and then decrease with increasing tunneling at higher biases. Such dissimilarities clearly point out that different exciton dynamics govern these two spectral measurements. We also argue why such quantum confined dipoles of indirect excitons can have thermodynamically finite probabilities to survive even at room temperature. Finally, our observations demonstrate that photocapacitance technique, which was seldom used to detect excitons in the past, is useful for selective detection and experimental tuning of relatively small numbers (~10^11/cm2) of photo-generated indirect excitons having large effective dipole moments in this type of quasi-two dimensional heterostructures.

title: Attracting teachers to remote Tasmanian communities and encouraging them to stay
Creators: name: Mackenzie, JE
Publisher: name: University of Tasmania

description: Attracting teachers to, and retaining them in, remote and isolated areas has been an ongoing issue nationally and internationally. The literature shows the majority of strategies designed to address it have focused on attracting teachers. These strategies are commonly aimed at graduate teachers, and current practice in Tasmania is no different. This study used mixed methods to investigate why teachers choose to teach in remote Tasmanian communities, why teachers leave remote communities, strategies and practices being used to attract and retain teachers to remote communities, and how these strategies and practices might be improved or added to. Past teachers and principals, teachers and principals working in the communities in 2015, a non-school based Tasmanian Department of Education employee, University of Tasmania Faculty of Education pre-service teacher educators, pre-service teachers who were in their final year of their initial teacher education program in 2015, and remote community members in the remote communities were involved in this study. Data analysis revealed that the majority of teachers that go to the remote community are beginning teachers, are lured by permanency, and leave after 3 years. It was found that current practice does not attract experienced teachers (and principals) resulting in a lack of collegial support and mentoring for beginning teachers. A key finding was that responsibility for attracting and retaining teachers to remote Tasmanian communities does not lie just with the Tasmanian Department of Education. The University of Tasmania Faculty of Education plays a key role to influence attraction, and principals in remote schools, and the remote communities themselves play key roles in influencing retention. The study suggests improvement of practice and concludes with recommendations that have the potential to result in a different approach in thinking about these issues in Tasmania and beyond.

Magnetic disorder in superconductors: Enhancement by mesoscopic fluctuations

description: We study the density of states (DOS) and the transition temperature $T_c$ in a dirty superconducting film with rare classical magnetic impurities of an arbitrary strength described by the Poissonian statistics. We take into account that the potential disorder is a source for mesoscopic fluctuations of the local DOS, and, consequently, for the effective strength of magnetic impurities. We find that these mesoscopic fluctuations result in a non-zero DOS for all energies in the region of the phase diagram where without this effect the DOS is zero within the standard mean-field theory. This mechanism can be more efficient in filling the mean-field superconducting gap than rare fluctuations of the potential disorder (instantons). Depending on the magnetic impurity strength, the suppression of $T_c$ by spin-flip scattering can be faster or slower than in the standard mean-field theory.
