description: Most histories and reports of Mount Morgan concentrate on the mining experience and financial achievements of the first Company rather than the mining town. This dissertation presents a social history of Mount Morgan that addresses the establishment, rise and fall of the town during the period of the first syndicate and succeeding company, 1883-1927. The thesis contends that the transformation of the landscape was to industrial, urban space where the working-class attitudes of miners and others defined a town character, despite the aspiration of many to social status through private enterprise and public influence. Further, the scope of research encompassed local involvement in colonial and state politics, and the presence of local government authority, law courts and press that placed an urban stamp on the town. Issues discussed also relate to geographic, climatic and single company influences that caused the difference between Mount Morgan and other mining towns that did not survive. The traditional perception of mining town impermanence was contradicted at Mount Morgan, where town and suburban communities were witness to a range of collective support in religious adherence, benefit associations, fraternalism and ritual, leisure, sport, education, and social cohesion in times of mining disaster. Moreover, despite increasing familial connections, antagonistic attitudes prevailed between the defensively parochial town of Mount Morgan and the nearby regional centre of Rockhampton. The rise of unionism at Mount Morgan challenged an apathetic working-class population to workplace solidarity in reaction to the Company's long established, almost feudal control of the town as well as the mine. It is argued that, despite a decade of failing ore markets and soaring production costs at the mine, the attitudes and actions of a union dominated workforce were paramount in decline of the town and ultimate closure of the mine. Mount Morgan survived the exodus of thousands of residents. A defiant place, the town exhibited a pride bolstered by the perpetuation of myths that presented a public image shielded from the life-long realities of economic and social adversity.

description: The power spectrum of the nonlinearly evolved large-scale mass distribution recovers only a minority of the information available on the mass fluctuation amplitude. We investigate the recovery of this information in 2D "slabs" of the mass distribution averaged over $\approx100$~$h^{-1}$Mpc along the line of sight, as might be obtained from photometric redshift surveys. We demonstrate a Hamiltonian Monte Carlo (HMC) method to reconstruct the non-Gaussian mass distribution in slabs, under the assumption that the projected field is a point-transformed Gaussian random field, Poisson-sampled by galaxies. When applied to the \textit{Quijote} $N$-body suite at $z=0.5$ and at a transverse resolution of 2~$h^{-1}$Mpc, the method recovers $\sim 30$ times more information than the 2D power spectrum in the well-sampled limit, recovering the Gaussian limit on information. At a more realistic galaxy sampling density of $0.01$~$h^3$Mpc$^{-3}$, shot noise reduces the information gain to a factor of 5 improvement over the power spectrum at resolutions of 4~$h^{-1}$Mpc or smaller.

description: Designs, develops and implements an online survey to identify physical learning environments and resources students use when studying an online course.. This research involved the design, development and implementation of an online survey instrument to identify the physical learning environments and resources students use when studying an online course. It was found, through a review of the literature, that there was no appropriate instrument available for this purpose. It was also found that the term physical learning environment actually is not well defined in the literature. These two factors have been addressed in this research. The results obtained from the survey found that students used a mixture of physical learning resources such as textbooks, and online resources such as email and online submission of assessment items. However, none of these resources were used all the time. It was also established that the majority of students preferred to learn at home using either online or paper-based resource material. The results also showed that the library both as a resource and as a learning environment was not being used to its full potential.

description: We calculate thermodynamic properties of soft-core lattice bosons with on-site $n$-body interactions using up to twelfth and tenth order strong coupling expansion in one and two dimensional cubic lattices at zero temperature. Using linked cluster techniques, we show that it is possible to exactly renormalize the two-body interactions for quasiparticle excitations and ground-state energy by resumming the three and four body terms in the system, which suggests that all higher-body on-site interactions may be exactly and perturbatively resummed into the two-body terms for similar system observables. The renormalization procedure that we develop is applicable to a broad range of systems analyzable by linked cluster expansions, ranging from perturbative quantum chromodynamics to spin models, giving either an exact or approximate resummation depending on the specific system and properties. Universality at various three-body interaction strengths for the two dimensional boson Hubbard model is checked numerically.

description: Endometrial cancer is a common malignant gynecological tumor, but there are few biomarkers that are useful for early and accurate diagnosis and few treatments other than surgery. However, use of microRNAs (miRNAs) that induces gene downregulation in cells may permit effective and minimally invasive diagnosis and treatment. In endometrial cancer cells, expression levels of miRNAs including miR-185, miR-210 and miR-423 are upregulated and those of miR-let7e, miR-30c and miR-221 are downregulated compared to normal tissues, and these miRNAs are involved in carcinogenesis, invasion and metastasis. miRNAs with expression changes such as miR-181b, miR-324-3p and miR-518b may be used as prognostic biomarkers and transfection of miR-152 may inhibit cancer growth. However, most current studies of miRNAs are at a basic level and further work is needed to establish clinical applications targeting miRNAs.

description: Solvable critical dense polymers is a Yang-Baxter integrable model of polymers on the square lattice. It is the first member LM(1,2) of the family of logarithmic minimal models LM(p,p'). The associated logarithmic conformal field theory admits an infinite family of Kac representations labelled by the Kac labels r,s=1,2,.... In this paper, we explicitly construct the conjugate boundary conditions on the strip. The boundary operators are labelled by the Kac fusion labels (r,s)=(r,1) x (1,s) and involve a boundary field xi. Tuning the field xi appropriately, we solve exactly for the transfer matrix eigenvalues on arbitrary finite-width strips and obtain the conformal spectra using the Euler-Maclaurin formula. The key to the solution is an inversion identity satisfied by the commuting double-row transfer matrices. The transfer matrix eigenvalues are classified by the physical combinatorics of the patterns of zeros in the complex spectral-parameter plane. This yields selection rules for the physically relevant solutions to the inversion identity which takes the form of a decomposition into irreducible blocks corresponding combinatorially to finitized characters given by generalized q-Catalan polynomials. This decomposition is in accord with the decomposition of the Kac characters into irreducible characters. In the scaling limit, we confirm the central charge c=-2 and the Kac formula for the conformal weights Delta_{r,s}=((2r-s)^2-1)/8 for r,s=1,2,3,... in the infinitely extended Kac table.

description: Nanostructured materials have recently emerged as a promising approach for material appearance design. Research has mainly focused on creating structural colours by wave interference, leaving aside other important aspects that constitute the visual appearance of an object, such as the respective weight of specular and diffuse reflectances, object macroscopic shape, illumination and viewing conditions. Here, we report the potential of disordered optical metasurfaces for harnessing visual appearance. We develop a multiscale modelling platform for the predictive rendering of macroscopic objects covered by metasurfaces in realistic settings, showing how nanoscale resonances and mesoscale interferences can be used to spectrally and angularly shape reflected light and thus create unusual visual effects at the macroscale. We validate this property with realistic synthetic images of macroscopic objects and centimetre-scale samples observable with the naked eye. This framework opens new perspectives in many branches of fine and applied visual arts.

description: We address the inverse problem of local volatility surface calibration from market given option prices. We integrate the ever-increasing flow of option price information into the well-accepted local volatility model of Dupire. This leads to considering both the local volatility surfaces and their corresponding prices as indexed by the observed underlying stock price as time goes by in appropriate function spaces. The resulting parameter to data map is defined in appropriate Bochner-Sobolev spaces. Under this framework, we prove key regularity properties. This enable us to build a calibration technique that combines online methods with convex Tikhonov regularization tools. Such procedure is used to solve the inverse problem of local volatility identification. As a result, we prove convergence rates with respect to noise and a corresponding discrepancy-based choice for the regularization parameter. We conclude by illustrating the theoretical results by means of numerical tests.

The research provides Queensland data and results on a structural timetable reform initiative that currently is only trialled or used by a small percentage of secondary public or private schools in the State. This initiative is the organisation of the school day into distinct split-shifts. This reform factor is related to the impact that facilities and facility issues have on teaching and learning. Not only does this research make an original contribution to knowledge and provide valuable data for policy makers, but it can also be used to inform practical, on-the-ground reform in schools. Currently for schools interested in challenging traditional approaches to the school day by adopting this reform, searches reveal a dearth of Australian research." -- abstract

description: Given a reconfigurable system X, such as a robot moving on a grid or a set of particles traversing a graph without colliding, the possible positions of X naturally form a cubical complex S(X). When S(X) is a CAT(0) space, we can explicitly construct the shortest path between any two points, for any of the four most natural metrics: distance, time, number of moves, and number of steps of simultaneous moves. CAT(0) cubical complexes are in correspondence with posets with inconsistent pairs (PIPs), so we can prove that a state complex S(X) is CAT(0) by identifying the corresponding PIP. We illustrate this very general strategy with one known and one new example: Abrams and Ghrist's positive robotic arm on a square grid, and the robotic arm in a strip. We then use the PIP as a combinatorial "remote control" to move these robots efficiently from one position to another.

description: With the global issue of plastic debris ever expanding, it is about time that the technology industry stepped in. This study aims to assess whether deep learning can successfully distinguish between marine life and man-made debris underwater. The aim is to find if we are safely able to clean up our oceans with Artificial Intelligence without disrupting the delicate balance of the aquatic ecosystems. The research explores the use of Convolutional Neural Networks from the perspective of protecting the ecosystem, rather than primarily collecting rubbish. We did this by building a custom-built, deep learning model, with an original database including 1,644 underwater images and used a binary classification to sort synthesised material from aquatic life. We concluded that although it is possible to safely distinguish between debris and life, further exploration with a larger database and stronger CNN structure has the potential for much more promising results.

description: It is shown that a disformally coupled theory in which the gravitational sector has the Einstein-Hilbert form is equivalent to a quartic DBI Galileon Lagrangian, possessing non-linear higher derivative interactions, and hence allowing for the Vainshtein effect. This Einstein Frame description considerably simplifies the dynamical equations and highlights the role of the different terms. The study of highly dense, non-relativistic environments within this description unravels the existence of a disformal screening mechanism, while the study of static vacuum configurations reveals the existence of a Vainshtein radius, at which the asymptotic solution breaks down. Disformal couplings to matter also allow the construction of Dark Energy models, which behave differently than conformally coupled ones and introduce new effects on the growth of Large Scale Structure over cosmological scales, on which the scalar force is not screened. We consider a simple Disformally Coupled Dark Matter model in detail, in which standard model particles follow geodesics of the gravitational metric and only Dark Matter is affected by the disformal scalar field. This particular model is not compatible with observations in the linearly perturbed regime. Nonetheless, disformally coupled theories offer enough freedom to construct realistic cosmological scenarios, which can be distinguished from the standard model through characteristic signatures.

An exploration of strategy processes and stakeholder involvement in implementation in Queensland regional economic development organisations

description: "Strategy offers regional stakeholders an opportunity to collaboratively influence the future direction of their regions economy. However, limited research has been undertaken with respect to strategy processes that are being used by regional economic development organisations. While there are suggestions for the ideal content of regional economic development strategies, the processes by which these organisations develop and implement strategy have not been investigated. This thesis documents an exploratory research project that utilises a case study methodology to identify and consider the processes applied in three different regional economic development organisations. In order to appreciate the context of regional strategy development, theory on regions, collaboration and strategy is integrated to develop a detailed theoretical framework of twenty seven elements that are thought to contribute to implementation. The presence or absence of these elements in each of the three cases is explored deductively through a review of internal documents and semi-structured interviews with a mix of regional stakeholders. Elements are investigated within cases to understand how strategy is being applied within each particular context. Analysis across cases is documented, identifying both similarities and differences in the presence and absence of elements. The research found that relationships were important to the continuing future of the organisations. Long term planning was absent in all cases and this absence was attributed to contextual factors such as a dynamic external environment, and a dependence on government funding leading to short term planning cycles. There was also a lack of clarity regarding organisational goals. The processes utilised in all cases most closely matched Mintzberg and Waters (1998) umbrella strategy, however, all organisations lacked a strategic approach. A tentative model was developed to depict elements thought to be the most significant to collaborative regional strategy implementation. These elements are: leadership on strategic planning; good member to member relationships; realism; long term goals; performance measures tied to long term goals; ongoing review and updating of the strategic plan; relevance of the strategic plan; and consistency of activities with the strategic plan. The need for further research to investigate these potential relationships was indicated." -- abstract.

description: We analyze the analytic structure of the Covariant Spectator Theory (CST) contribution to the self-energy amplitude for a scalar particle in a ϕ^2 χ-theory. To this end we derive dispersion relations in 1+1 and in 3+1 dimensional Minkowski space. The divergent loop integrals in 3+1 dimensions are regularized using dimensional regularization. We find that the CST dispersion relations exhibit, in addition to the usual right-hand branch cut, also a left-hand cut. The origin of this "spectator" left-hand cut can be understood in the context of scattering for a scalar ϕ^2 χ^2-type theory. If the interaction kernel contains a linear confining component, its contribution to the self-energy vanishes exactly.

description: Quantum information processing using linear optics is challenging due to the limited set of deterministic operations achievable without using complicated resource-intensive methods. While techniques such as the use of ancillary photons can enhance the information processing capabilities of linear optical systems they are technologically demanding. Therefore, determining the constraints posed by linear optics and optimizing linear optical operations for specific tasks under those constraints, without the use of ancillas, can facilitate their potential implementation. Here, we consider the task of unambiguously discriminating between Bell-like states without the use of ancillary photons. This is a basic problem relevant in diverse settings, for example, in the measurement of the output of an entangling quantum circuit or for entanglement swapping at a quantum repeater station. While it is known that exact Bell states of two qubits can be discriminated with an optimal success probability of 50% we find, surprisingly, that for Bell-like states the optimal probability can be only 25%. We analyze a set of Bell-like states in terms of their distinguishability, entanglement as measured by concurrence, and parameters of the beam-splitter network used for unambiguous discrimination. Further, we provide the linear optical configuration comprised of single photon detectors and beam splitters with input state-dependent parameters that achieves optimal discrimination in the Bell-like case.

description: Sub-diffraction-limit resolution, or super-resolution, had been successfully demonstrated by recent theoretical and experimental studies for two-point sources with ideal equal-brightness and strict incoherenceness. Unfortunately, practical situations of either non-equal brightness (i.e., unbalancenss) or partial coherence are shown to have fatal effects on resolution precision. As a step toward resolving such issues, we consider both effects together by including an entangled partner of the two-point sources. Unexpectedly, it is found that the two negative effects can counter affect each other, thus permitting credible super-resolution, when the measurement is analyzed in the entangled partner's rotated basis. A least resolvable finite two-source separation is also identified analytically. Our result represents useful guidance towards the realization of super-resolution for practical point sources. The vector-structure analog of quantum and classical light sources also suggests that our analysis applies to both contexts.

description: " S2Learning on the RunS3 refers to the educational experiences of the primary school children travelling along the agricultural show circuits in coastal and western Queensland. This thesis examines those educational experiences by drawing on the voices of the show children, their parents, their home tutors and their teachers from the Brisbane School of Distance Education, which from 1989 to 1999 implemented a specialised program of Traveller education for these children (in 2000 a separate school was established for them). The thesis focusses on the interplay among marginalisation, resistance and transformation in the spaces of the show peoples itinerancy. It deploys Michel de Certeaus (1984, 1986) concept of tactics of consumption and Mikhail Bakhtins (1986a) notions of outsiddness and creative understanding to interrogate the show peoples engagement with their absence of place, the construction of their otherness and forms of seemingly unproblematic knowledge about their schooling. Data gathering techniques included semi-structured interviews with forty-two people between 1992 and 2000 in seven sites in Queensland - Mackay, Bundaberg (over two years), Emerald, Brisbane, Rockhampton and Yeppoon - and document collection. The thesiss major finding is that the show peoples resistance and transformation of their marginalising experiences have enabled them to initiate and implement a significant counternarrative to the traditional narrative (and associated stereotypes) attending their itinerancy. This counternarrative has underpinned a fundamental change in their schooling provision, from a structure that worked to marginalise and disempower them to a specialised form of Traveller education. This change contributes crucially to understanding and theorising the spaces of itinerancy, and highlights the broader significance of the Queensland show peoples S2learning on the runS3.

description: Gapless edge states are the hallmark of a large class of topological states of matter. Recently, intensive research has been devoted to understanding the physical properties of the edge states at the quantum phase transitions of the bulk topological states. A higher-order symmetry-protected topological state is realized in a plaquette Heisenberg model on the square lattice. In its disordered phase, the lattice with an open boundary hosts either dangling corner states with spin-$1/2$ degeneracy characterizing the topological phase, or nondangling corner states without degeneracy, which depends on the bond configuration near the corners. In this work, we study the critical behavior of these corner states at the quantum critical point (QCP), and find that the spin-$1/2$ corner state induces a new universality class of the corner critical behavior, which is distinct from the ordinary transition of the nondangling corners. In particular, we find that the dangling spin-$1/2$ corner state persists at the QCP despite its coupling to the critical spin fluctuations in the bulk. This shows the robustness of the corner state of the higher-order topological state.

description: The central density rho_0 of a stellar cluster is an important physical parameter for determining its evolutionary and dynamical state. How much mass segregation there is, or whether the cluster has undergone core collapse both depends on rho_0. We reanalyze the results of a previous paper that gives the mass density profile of R136 and combine them with both a conservative upper limit for the core parameter and a more uncertain recent measurement. We thus place a lower limit on rho_0 under reasonable and defensible assumptions about the IMF, finding rho_0 >~ 1.5x10^4 Msun/pc^3 for the conservative assumption a < 0.4 pc for the cluster core parameter. If we use the lower, but more uncertain value a = 0.025 pc, the central density estimate becomes greater than 10^7 Msun/pc^3. A mechanism based on the destruction of a large number of circumstellar disks is posited to explain the hitherto unexplained increase in reddening presented in that same work.

description: A laser-induced fluorescence (LIF) technique is described to measure two-dimensional vertical concentration profiles of gases in the aqueous mass boundary layer at a free water surface. The technique uses an acid-base reaction of the fluorescence indicator fluorescein at the water surface to visualize the concentration profiles. It is shown that this technique is capable of measuring the

two-dimensional vertical concentration profiles at a rate of 200 frames per second with a spatial resolution of 20 µm. The results show that the decrease of the measured mean concentration profiles into the bulk is faster than predicted by the small eddy model. The measurements agree with the predictions of the surface renewal model. Combined experiments with a wave slope imaging technique reveal that there is no local correlation between wave slope and boundary layer thickness. The image sequences indicate that there is only a weak correlation between the occurrence of surface renewal phenomena and steep wave trains. Surface renewal effects for a fully developed wave field renew the fluid in the aqueous mass boundary layer up to the water surface. This is not true for the case of a flat interface. Here, the changes of the boundary layer thickness after a surface renewal event are significantly smaller.

Deviations from the minimum uncertainty states were observed due to the absence of the Gaussian nature. In our study of the entropy, we noticed that with increasing vorticity, entropy increases for both the modes. We further observed that, there exists an optimum value of ellipticity which gives rise to maximum entanglement of the two modes of the quantum elliptical vortex states. A further increase in ellipticity reduces the entropy thereby resulting in a loss of information carrying capacity. We check the validity of the entropic inequality relations, namely the subaddivity and the Araki-Lieb inequality. The later was satisfied only for a very small range of the ellipticity of the vortex while the former seemed to be valid at all values.

description: We prove that one of the conditions in M.V. Zaicev's formula for the PI-exponent and in its natural generalization for the Hopf PI-exponent, can be weakened. Using the modification of the formula, we prove that if a finite dimensional semisimple Lie algebra acts by derivations on a finite dimensional Lie algebra over a field of characteristic $0$, then the differential PI-exponent coincides with the ordinary one. Analogously, the exponent of polynomial $G$-identities of a finite dimensional Lie algebra with a rational action of a connected reductive affine algebraic group $G$ by automorphisms, coincides with the ordinary PI-exponent. In addition, we provide a simple formula for the Hopf PI-exponent and prove the existence of the Hopf PI-exponent itself for $H$-module Lie algebras whose solvable radical is nilpotent, assuming only the $H$-invariance of the radical, i.e. under weaker assumptions on the $H$-action, than in the general case. As a consequence, we show that the analog of Amitsur's conjecture holds for $G$-codimensions of all finite dimensional Lie $G$-algebras whose solvable radical is nilpotent, for an arbitrary group $G$.

Multistage Adaptive Estimation of Sparse Signals

description: This paper considers sequential adaptive estimation of sparse signals under a constraint on the total sensing effort. The advantage of adaptivity in this context is the ability to focus more resources on regions of space where signal components exist, thereby improving performance. A dynamic programming formulation is derived for the allocation of sensing effort to minimize the expected estimation loss. Based on the method of open-loop feedback control, allocation policies are then developed for a variety of loss functions. The policies are optimal in the two-stage case, generalizing an optimal two-stage policy proposed by Bashan et al., and improve monotonically thereafter with the number of stages. Numerical simulations show gains up to several dB as compared to recently proposed adaptive methods, and dramatic gains compared to non-adaptive estimation. An application to radar imaging is also presented.

description: Bounds to the speed of evolution of a quantum system are of fundamental interest in quantum metrology, quantum chemical dynamics and quantum computation. We derive a time-energy uncertainty relation for open quantum systems undergoing a general, completely positive and trace preserving (CPT) evolution which provides a bound to the quantum speed limit. When the evolution is of the Lindblad form, the bound is analogous to the Mandelstam-Tamm relation which applies in the unitary case, with the role of the Hamiltonian being played by the adjoint of the generator of the dynamical semigroup. The utility of the new bound is exemplified in different scenarios, ranging from the estimation of the passage time to the determination of precision limits for quantum metrology in the presence of dephasing noise.

Antipodean Gothic cinema: A study of the (postmodern) Gothic in Australian and New Zealand film since the 1970s

subject: Screen and media culture

description: Although various film critics and academics have located the Gothic in Antipodean cinema, there has been no in-depth study of the Gothic and its ideological entanglements with postmodernism within this cinema. This study is divided into two parts and locates the (postmodern) Gothic in twelve Australian/New Zealand films ranging from Ted Kotcheff’s Wake in Fright (1971) to Peter Jackson’s Heavenly Creatures (1994). Part one theorizes the Gothic as a subversive cultural mode that foreshadows postmodernism in terms of its antithetical relationship with Enlightenment ideals. Interconnections are made between proto-postmodern aspects of early Gothic literature and the appropriation and intensification of these aspects in what has been dubbed the postmodern Gothic. The dissertation then argues that the Antipodes was/is constructed through Euro-centric discourse(s) as a Gothic/(proto)-postmodern space or place, this construction manifest in, and becoming intertwined with the postmodern in post 1970s Antipodean cinema. In part two, a cross-section of Australian/New Zealand films is organized into cinematic sub-genres in line with their similar thematic preoccupations and settings, all films argued as reflecting a marked postmodern Gothic sensibility. In its conclusion, the study finds that “Antipodean Gothic cinema”, particularly since the 1970s, can be strongly characterized by its combining of Gothic/postmodernist modes of representation, this convergence constitutive of a postmodernized version of the Gothic which is heavily influenced by Euro-centric constructions of the Antipodes in Gothic/(proto)-postmodern related terms.
Stable XOR-based Policies for the Broadcast Erasure Channel with Feedback

description: In this paper we describe a network coding scheme for the Broadcast Erasure Channel with multiple unicast stochastic flows, in the case of a single source transmitting packets to $N$ users, where per-slot feedback is fed back to the transmitter in the form of ACK/NACK messages. This scheme performs only binary (XOR) operations and involves a network of queues, along with special rules for coding and moving packets among the queues, that ensure instantaneous decodability. The system under consideration belongs to a class of networks whose stability properties have been analyzed in earlier work, which is used to provide a stabilizing policy employing the currently proposed coding scheme. Finally, we show the optimality of the proposed policy for $N=4$ and i.i.d. erasure events, in the sense that the policy's stability region matches a derived outer bound (which coincides with the system's information-theoretic capacity region), even when a restricted set of coding rules is used.

A Measurement of the Cosmic Expansion Within our Lifetime

description: The most exciting future observation in cosmology will feature a monitoring of the cosmic expansion in real time, unlike anything that has ever been attempted before. This campaign will uncover crucial physical properties of the various constituents in the Universe, and perhaps answer a simpler question concerning whether or not the cosmic expansion is even accelerating. An unambiguous yes/no response to this query will significantly impact cosmology, of course, but also the standard model of particle physics. Here, we discuss -- in a straightforward way -- how to understand the so-called `redshift drift' sought by this campaign, and why its measurement will help us refine the standard-model parameters if the answer is `yes.' A `no' answer, on the other hand, could be more revolutionary, in the sense that it might provide a resolution of several long-standing problems and inconsistencies in our current cosmological models. An outcome of zero redshift drift, for example, would obviate the need for a cosmological constant and render inflation completely redundant.
