description: This paper extends the existing drawdown modulation control policy to include a novel restart mechanism for trading. It is known that the drawdown modulation policy guarantees the maximum percentage drawdown no larger than a prespecified drawdown limit for all time with probability one. However, when the prespecified limit is approaching in practice, such a modulation policy becomes a stop-loss order, which may miss the profitable follow-up opportunities if any. Motivated by this, we add a data-driven restart mechanism into the drawdown modulation trading system to auto-tune the performance. We find that with the restart mechanism, our policy may achieve a superior trading performance to that without the restart, even with a nonzero transaction costs setting. To support our findings, some empirical studies using equity ETF and cryptocurrency with historical price data are provided.

description: We show that an arbitrary nilprogression can be approximated by a proper coset nilprogression in upper-triangular form. This can be thought of as a nilpotent version of the Freiman-Bilu result that a generalised arithmetic progression can be efficiently contained in a proper generalised arithmetic progression, and indeed an important ingredient in the proof is a Lie-algebra version of the geometry-of-numbers argument at the centre of that result. We also present some applications. We verify a conjecture of Benjamini that if $S$ is a symmetric generating set for a group such that $1\in S$ and $|S^n|\le Mn^D$ at some sufficiently large scale $n$ then $S$ exhibits polynomial growth of the same degree $D$ at all subsequent scales, in the sense that $|S^r|\ll_{M,D}r^D$ for every $r\ge n$. Our methods also provide an important ingredient in a forthcoming companion paper in which we reprove and sharpen a result about scaling limits of vertex-transitive graphs of polynomial growth due to Benjamini, Finucane and the first author. We also note that our arguments imply that every approximate group has a large subset with a large quotient that is Freiman isomorphic to a subset of a torsion-free nilpotent group of bounded rank and step.

title: Multi-frequency matching, classification, and cosmic evolution of radio galaxy populations
Creators: name: Swan, JE
Publisher: name: University of Tasmania
Year: 2018

description: This thesis combines the third data release of the Australia Telescope Large Area Survey (ATLAS) with complimentary DES photometry and OzDES targeted spectroscopy. ATLAS 1:4 GHz is a deep (< 20 μJy/beam) survey of the combined 6:3 deg\(^2\) sky area of CDFS and ELAIS-S1. Cross-matching of 4903 ATLAS sources to photometric and spectroscopic counterparts is performed visually using custom interactive software: MCVCM. I compare the results from this visual matching to results from simple coordinate-based nearest-neighbour matching. The visually constructed catalogues are substantially more robust due to a better accounting of chance alignments and dense field mismatches. Both cross-matching techniques are performed directly from radio-to-optical, and indirectly by matching radio sources to an infrared-optical paired catalogue. There is a definite improvement for both visual and nearest-neighbour cross-matching when performed via SWIRE infrared intermediary catalogue. I use the visual catalogue to build a reliable sample of ATLAS sources matched to SWIRE infrared photometry, DES optical photometry, and OzDES spectra. This catalogue was developed carefully and is intended to for use as a comparison and training catalogue for the development of intelligent automated cross-matching algorithms. Galaxies are segregated into star-forming and AGN populations using a combination of visual spectral classification, morphology, multi-frequency diagnostics, and optical spectral line diagnostics. For these populations, 1:4 GHz radio luminosity functions (RLFs) are constructed incrementally out to a redshift z < 1.0. These results improve upon ATLAS-DR1 RLFs and agree with established literature results. Evidence of the space-density evolution of radio source is apparent for both populations towards higher redshifts, indicating increased star-formation and AGN luminosity in earlier cosmic epochs. I construct RLFs for both visual galaxy classification and a combined classification based on a novel numerical combination of classification diagnostics. The combined classification provides higher reliability and completeness resulting in less confounded and deeper RLF. Cross-matching techniques capable of identifying extended and confounded radio sources combined with a robust galaxy classification scheme are therefore essential for quantifying the evolution of radio galaxy populations.

description: Mutational loss of CDKN2A (encoding p16INK4A) tumor-suppressor function is a key genetic step that complements activation of KRAS in promoting the development and malignant growth of pancreatic ductal adenocarcinoma (PDAC). However, pharmacologic restoration of p16INK4A function with inhibitors of CDK4 and CDK6 (CDK4/6) has shown limited clinical efficacy in PDAC. Here, we found that concurrent treatment with both a CDK4/6 inhibitor (CDK4/6i) and an ERK-MAPK inhibitor (ERKi) synergistically suppresses the growth of PDAC cell lines and organoids by cooperatively blocking CDK4/6i-induced compensatory upregulation of ERK, PI3K, antiapoptotic signaling, and MYC expression. On the basis of these findings, a Phase I clinical trial was initiated to evaluate the ERKi ulixertinib in combination with the CDK4/6i palbociclib in patients with advanced PDAC (NCT03454035). As inhibition of other proteins might also counter CDK4/6i-mediated signaling changes to increase cellular CDK4/6i sensitivity, a CRISPR-Cas9 loss-of-function screen was conducted that revealed a spectrum of functionally diverse genes whose loss enhanced CDK4/6i growth inhibitory activity. These genes were enriched around diverse signaling nodes, including cell-cycle regulatory proteins centered on CDK2 activation, PI3K-AKT-mTOR signaling, SRC family kinases, HDAC proteins, autophagy-activating pathways, chromosome regulation and maintenance, and DNA damage and repair pathways. Novel therapeutic combinations were validated using siRNA and small-molecule inhibitor-based approaches. In addition, genes whose loss imparts a survival advantage were identified (e.g., RB1, PTEN, FBXW7), suggesting possible resistance mechanisms to CDK4/6 inhibition. In summary, this study has identified novel combinations with CDK4/6i that may have clinical benefit to patients with PDAC.
SIGNIFICANCE: CRISPR-Cas9 screening and protein activity mapping reveal combinations that increase potency of CDK4/6 inhibitors and overcome drug-induced compensations in pancreatic cancer.

description: A finite-dimensional CAT(0) cube complex $X$ is equipped with several well-studied boundaries. These include the Tits boundary (which depends on the CAT(0) metric), the Roller boundary (which depends only on the combinatorial structure), and the simplicial boundary (which also depends only on the combinatorial structure). We use a partial order on a certain quotient of the Roller boundary to obtain the simplicial Roller boundary. Then, we show that the Tits, simplicial, and simplicial Roller boundaries are all homotopy equivalent, $Aut(X)$--equivariantly up to homotopy. As an application, we deduce that the perturbations of the CAT(0) metric introduced by Qing do not affect the equivariant homotopy type of the Tits boundary. Along the way, we develop a self-contained exposition providing a dictionary among different perspectives on cube complexes.

description: This article describes F-IVM, a unified approach for maintaining analytics over changing relational data. We exemplify its versatility in four disciplines: processing queries with group-by aggregates and joins; learning linear regression models using the covariance matrix of the input features; building Chow-Liu trees using pairwise mutual information of the input features; and matrix chain multiplication.
 F-IVM has three main ingredients: higher-order incremental view maintenance; factorized computation; and ring abstraction. F-IVM reduces the maintenance of a task to that of a hierarchy of simple views. Such views are functions mapping keys, which are tuples of input values, to payloads, which are elements from a ring. F-IVM also supports efficient factorized computation over keys, payloads, and updates. Finally, F-IVM treats uniformly seemingly disparate tasks. In the key space, all tasks require joins and variable marginalization. In the payload space, tasks differ in the definition of the sum and product ring operations.
 We implemented F-IVM on top of DBToaster and show that it can outperform classical first-order and fully recursive higher-order incremental view maintenance by orders of magnitude while using less memory.
Clinical trials in pregnancy and the “shadows of thalidomide”: Revisiting the legacy of Frances Kelsey

Publisher: name: Elsevier
Year: 2022

description: Despite great need for improved understanding of the use of drugs and biological products in pregnancy, clinical trials in pregnancy are rare, therapeutics in pregnancy are woefully understudied, and pregnant individuals are routinely excluded as trial participants. Recently, however, the U.S. Food and Drug Administration (FDA) has signaled strong support for advancing scientific research with pregnant populations, marking a significant shift from the past. Over the last sixty years, precaution and fear have largely characterized clinical research in pregnancy, deriving in large part from a protectionist ethic that materialized after the thalidomide drug disaster. FDA reviewer Frances Kelsey courageously prevented thalidomide from being marketed in the United States, and her work guided and solidified the FDA's image as protector of the general population from unsafe and ineffective drugs. Yet, when it comes to protection, pregnant persons have been left behind, and experts refer to the "shadows of thalidomide" that hamper clinical trials in pregnancy. Drawing on analysis of Frances Kelsey's archived papers in addition to focused media coverage of Kelsey and thalidomide, we discuss the durable cultural narrative surrounding Kelsey's important work. We argue that revisiting Kelsey's legacy with attention to themes that have characterized her achievement-staying vigilant, prioritizing safety, and mitigating pharmaceutical-based harm-in fact facilitates progress toward the ethical obligation to protect pregnant people through research, toward the generation of pregnancy-specific data for evidence-based care, and toward realizing Kelsey's legacy of safeguarding pregnant people and their offspring from the harms of untested drugs.

description: Using a variational Monte Carlo method, we study competitions of strong electron-electron and electron-phonon interactions in the ground state of Holstein-Hubbard model on a square lattice. At half filling, an extended intermediate metallic or weakly superconducting (SC) phase emerges, sandwiched by antiferromagnetic and charge order (CO) insulating phases. By the carrier doping into the CO insulator, the SC order dramatically increases for strong electron-phonon couplings, but largely hampered by wide phase separation (PS) regions. Superconductivity is optimized at the border to the PS.

description: Atomic emitter ensembles couple collectively to the radiation field. Although an excitation on a single emitter may be short-lived, a collection of them can contain a photon several orders of magnitude longer than the single emitter lifetime. We provide the exact conditions for optimal absorption, long-lived and dispersionless storage, and release, of a single photon in a sub-wavelength one-dimensional lattice of two-level emitters. In particular, we detail two storage schemes. The first is based on the uncovering of approximate flat sections in the single-photon spectrum, such that a single photon can be stored as a wave packet with effective zero group velocity. For the second scheme we exploit the angular dependence of the interactions induced between the emitters and mediated via exchange of virtual photons, which on a ring gives rise to an effective trapping potential for the photon. In both cases, we are able to obtain, within current experimentally accessible parameters, high-fidelity photon storage for times hundreds of times longer than the single emitter lifetime.

description: We use chiral interactions and several ab initio methods to compute the nuclear matrix elements (NMEs) for ground-state-to-ground-state double Gamow-Teller transitions in a range of isotopes and explore the correlation of these NMEs with those for neutrinoless double beta decay produced by the exchange of a light Majorana neutrino. When all the NMEs of both isospin-conserving and isospin-changing transitions from the ab initio calculations are considered, the correlation is strong. For the experimentally relevant isospin-changing transitions by themselves, however, the correlation is weaker and may not be helpful for reducing the uncertainty in the NMEs for neutrinoless double beta decay.

description: Ultrasound is increasingly being used to modulate the properties of biological membranes for applications in drug delivery and neuromodulation. While various studies have investigated the mechanical aspect of the interaction such as acoustic absorption and membrane deformation, it is not clear how these effects transduce into biological functions, for example, changes in the permeability or the enzymatic activity of the membrane. A critical aspect of the activity of an enzyme is the thermal fluctuations of its solvation or hydration shell. Thermal fluctuations are also known to be directly related to membrane permeability. Here solvation shell changes of lipid membranes subject to an acoustic impulse were investigated using a fluorescence probe, Laurdan. Laurdan was embedded in multi-lamellar lipid vesicles in water, which were exposed to broadband pressure impulses of the order of 1MPa peak amplitude and 10μs pulse duration. An instrument was developed to monitor changes in the emission spectrum of the dye at two wavelengths with sub-microsecond temporal resolution. The experiments show that changes in the emission spectrum, and hence the fluctuations of the solvation shell, are related to the changes in the thermodynamic state of the membrane and correlated with the compression and rarefaction of the incident sound wave. The results suggest that acoustic fields affect the state of a lipid membrane and therefore can potentially modulate the kinetics of channels and proteins embedded in the membrane.
title: Surfactant pseudophases for open-tubular liquid chromatography and electrochromatography
Creators: name: Tarongoy, FM
Publisher: name: University of Tasmania
Year: 2018

description: Chromatographic science continues to take great interest in column development, particularly in discovering new materials for stationary phases that are efficient, stable, robust and selective. Open-tubular formats for microcolumns are regarded as advantageous due to the improved increased mass transfer, with very good chromatographic performance shown by theoretical studies. Surfactant-based separations by liquid chromatography and electrophoresis have long been established with surfactants above the critical micelle concentration (cmc). New liquid chromatography and electrochromatographic techniques are introduced here that exploit the molecular aggregates of surfactants below and above the cmc as immobile pseudophases suitable for open-tubular capillary columns. Electroosmotic flow measurements were used to characterise surface aggregation of two common ionic surfactants, hexadecyl- or cetyltrimethylammonium bromide (CTAB) and sodium dodecylsulfate (SDS), determining the cmc and the critical surface aggregation concentration (csac) that define admicelle and micellar formation. Admicelles formed between the csac and cmc were employed as soft and immobile pseudophases for the open-tubular admicellar liquid chromatography (OT-AMLC) and admicellar electrochromatography (OT-AMEC) of neutral (alkyl phenyl ketones, pesticides) and ionic (sulfonamides) analytes. Retention behaviour was ascertained using the relative retention times (RRT) showing similar values within the csac-to-cmc range, confirming admicelles were unaltered by pressure and electric field forces. Interfacial and solution micelles formed above the cmc govern the separation behaviour in open-tubular micellar liquid chromatography (OT-MLC) applied to neutral and ionic (food antioxidants) analytes and real sample matrices. Mobile phase conditions (pH, ionic strength, added salts and organic solvents) affected chromatographic behaviour. Analytical figures of merit (linearity, LOD, repeatability) have indicated acceptable employability of these techniques. This thesis introduces a new area of interest in separation science research.

description: Let $G$ be a simple algebraic group over an algebraically closed field $K$ with Lie algebra $\mathfrak{g}$. For unipotent elements $u \in G$ and nilpotent elements $e \in \mathfrak{g}$, the Jordan block sizes of $\operatorname{Ad}(u)$ and $\operatorname{ad}(e)$ are known in most cases. In the cases that remain, the group $G$ is of classical type in bad characteristic, so $\operatorname{char} K = 2$ and $G$ is of type $B_{\ell}$, $C_{\ell}$, or $D_{\ell}$.
 In this paper, we consider the case where $G$ is of type $C_{\ell}$ and $\operatorname{char} K = 2$. As our main result, we determine the Jordan block sizes of $\operatorname{Ad}(u)$ and $\operatorname{ad}(e)$ for all unipotent $u \in G$ and nilpotent $e \in \mathfrak{g}$. In the case where $G$ is of adjoint type, we will also describe the Jordan block sizes on $[\mathfrak{g}, \mathfrak{g}]$.

description: We consider layered decorated honeycomb lattices at two-thirds filling, as realized in some trinuclear organometallic complexes. Localized $S=1$ moments with a single-spin anisotropy emerge from the interplay of Coulomb repulsion and spin molecular-orbit coupling (SMOC). Magnetic anisotropies with bond dependent exchange couplings occur in the honeycomb layers when the direct intracluster exchange and the spin molecular-orbital coupling are both present. We find that the effective spin exchange model within the layers is an XXZ + 120$^\circ$ honeycomb quantum compass model. The intrinsic non-spherical symmetry of the multinuclear complexes leads to very different transverse and longitudinal spin molecular-orbital couplings, which greatly enhances the single-spin and exchange coupling anisotropies. The interlayer coupling is described by a XXZ model with anisotropic biquadratic terms. As the correlation strength increases the systems becomes increasingly one-dimensional. Thus, if the ratio of SMOC to the interlayer hopping is small this stabilizes the Haldane phase. However, as the ratio increases there is a quantum phase transition to the topologically trivial `$D$-phase'. We also predict a quantum phase transition from a Haldane phase to a magnetically ordered phase at sufficiently strong external magnetic fields.

description: Image deblurring continues to achieve impressive performance with the development of generative models. Nonetheless, there still remains a displeasing problem if one wants to improve perceptual quality and quantitative scores of recovered image at the same time. In this study, drawing inspiration from the research of transformer properties, we introduce the pretrained transformers to address this problem. In particular, we leverage deep features extracted from a pretrained vision transformer (ViT) to encourage recovered images to be sharp without sacrificing the performance measured by the quantitative metrics. The pretrained transformer can capture the global topological relations (i.e., self-similarity) of image, and we observe that the captured topological relations about the sharp image will change when blur occurs. By comparing the transformer features between recovered image and target one, the pretrained transformer provides high-resolution blur-sensitive semantic information, which is critical in measuring the sharpness of the deblurred image. On the basis of the advantages, we present two types of novel perceptual losses to guide image deblurring. One regards the features as vectors and computes the discrepancy between representations extracted from recovered image and target one in Euclidean space. The other type considers the features extracted from an image as a distribution and compares the distribution discrepancy between recovered image and target one. We demonstrate the effectiveness of transformer properties in improving the perceptual quality while not sacrificing the quantitative scores (PSNR) over the most competitive models, such as Uformer, Restormer, and NAFNet, on defocus deblurring and motion deblurring tasks.

description: Population III (Pop. III) binary stars likely produced the first stellar-born binary black hole (BBH) mergers in the Universe. Here, we quantify the main sources of uncertainty for the merger rate density evolution and mass spectrum of Pop. III BBHs by considering four different formation histories and 11 models of the initial orbital properties of Pop. III binary stars. The uncertainty on the orbital properties affects the BBH merger rate density by up to two orders of magnitude, models with shorter orbital periods leading to higher BBH merger rates. The uncertainty on the star formation history has a substantial impact on both the shape and the normalisation of the BBH merger rate density: the peak of the merger rate density shifts from $z\sim{8}$ up to $z\sim{16}$ depending on the assumed star formation rate, while the maximum BBH merger rate density for our fiducial binary population model spans from $\sim{2}$ to $\sim{30}$ Gpc$^{-3}$ yr$^{-1}$. The typical BBH masses are not affected by the star formation rate model and only mildly influenced by the binary population parameters. The primary black holes born from Pop. III stars tend to be rather massive ($30-40$ M$_\odot$) with respect to those born from metal-rich stars ($8-10$ M$_\odot$). We estimate that the Einstein Telescope will detect $10-10^4$ Pop. III BBH mergers per year, depending on the star formation history and binary star properties.

description: Polarization, understood as a division into mutually hostile groups, is a common feature of social systems. It is studied in Structural Balance Theory (SBT) in terms of semicycles in signed networks. However, enumerating semicycles is computationally expensive, so approximations are often needed. Here we introduce Multiscale Semiwalk Balance (MSB) approach for measuring degree of balance (DoB) in (un)directed, (un)weighted signed networks by approximating semicycles with closed semiwalks. It allows for selection of the resolution of analysis appropriate for assessing DoB motivated by Locality Principle (LP), which posits that patterns in shorter cycles are more important than in longer ones. Our approach overcomes several limitations affecting walk-based approximations, and provides methods for assessing DoB at various scales, from graphs to individual nodes, and for clustering signed networks. We demonstrate its effectiveness by applying it to real-world social systems, for which it produces explainable results consistent with expectations based on domain-specific knowledge.

description: Latency reversal strategies for HIV cure using inhibitor of apoptosis protein (IAP) antagonists (IAPi) induce unprecedented levels of latent reservoir expression without immunotoxicity during suppressive antiretroviral therapy (ART). However, full targeting of the reservoir may require combinatorial approaches. A Jurkat latency model screen for IAPi combination partners demonstrated synergistic latency reversal with bromodomain (BD) and extraterminal domain protein inhibitors (BETi). Mechanistic investigations using CRISPR-CAS9 and single-cell RNA-Seq informed comprehensive ex vivo evaluations of IAPi plus pan-BET, bD-selective BET, or selective BET isoform targeting in CD4+ T cells from ART-suppressed donors. IAPi+BETi treatment resulted in striking induction of cell-associated HIV gag RNA, but lesser induction of fully elongated and tat-rev RNA compared with T cell activation-positive controls. IAPi+BETi resulted in HIV protein induction in bulk cultures of CD4+ T cells using an ultrasensitive p24 assay, but did not result in enhanced viral outgrowth frequency using a standard quantitative viral outgrowth assay. This study defines HIV transcriptional elongation and splicing as important barriers to latent HIV protein expression following latency reversal, delineates the roles of BET proteins and their BDs in HIV latency, and provides a rationale for exploration of IAPi+BETi in animal models of HIV latency.

description: Fermi liquid theory works very well in most normal metals, but is found violated in many strongly correlated electron systems, such as cuprate and heavy-fermion superconductors. A widely accepted criterion is that, the Fermi liquid theory is valid when the interaction-induced fermion damping rate approaches zero more rapidly than the energy. Otherwise, it is invalid. Here, we demonstrate that this criterion breaks down in topological double-and triple-Weyl semimetals. Renormalization group analysis reveals that, although the damping rate of double- and triple-Weyl fermions induced by the Coulomb interaction approaches zero more rapidly than the energy, the quasiparticle residue vanishes and the Fermi liquid theory is invalid. This behavior indicates a weaker-than-marginal violation of the Fermi liquid theory. Such an unconventional non-Fermi liquid state originates from the special dispersion of double- and triple-Weyl fermions, and is qualitatively different from all the other Fermi-liquid and non-Fermi-liquid states. The predicted properties of the fermion damping rate and the spectral function can be probed by the angle-resolved photoemission spectroscopy. The density of states, specific heat, and conductivities are also calculated and analyzed after incorporating the corrections induced by the Coulomb interaction.

Why history matters: ab initio rederivation of Fresnel equations confirms microscopic theory of refractive index

description: We provide a systematic theoretical, experimental, and historical critique of the standard derivation of Fresnel's equations, which shows in particular that these well-established equations actually contradict the traditional, macroscopic approach to electrodynamics in media. Subsequently, we give a rederivation of Fresnel's equations which is exclusively based on the microscopic Maxwell equations and hence in accordance with modern first-principles materials physics. In particular, as a main outcome of this analysis being of a more general interest, we propose the most general boundary conditions on electric and magnetic fields which are valid on the microscopic level.

Visualization of alternating triangular domains of charge density waves in 2H-NbSe$_2$ by scanning tunneling microscopy

description: The charge density wave (CDW) state of 2H-NbSe$_2$ features commensurate domains separated by domain boundaries accompanied by phase slips known as discommensurations. We have unambiguously visualized the structure of CDW domains using a displacement-field measurement algorithm on a scanning tunneling microscopy image. Each CDW domain is delimited by three vertices and three edges of discommensurations and is designated by a triplet of integers whose sum identifies the types of commensurate structure. The observed structure is consistent with the alternating triangular tiling pattern predicted by a phenomenological Landau theory. The domain shape is affected by crystal defects and also by topological defects in the CDW phase factor. Our results provide a foundation for a complete understanding of the CDW state and its relation to the superconducting state.

description: The effect of monolayers of oxygen (O) and hydrogen (H) on the possibility of material transfer at aluminium/titanium nitride (Al/TiN) and copper/diamond (Cu/C$_{\text{dia}}$) interfaces, respectively, were investigated within the framework of density functional theory (DFT). To this end the approach, contact, and subsequent separation of two atomically flat surfaces consisting of the aforementioned pairs of materials were simulated. These calculations were performed for the clean as well as oxygenated and hydrogenated Al and C$_{\text{dia}}$ surfaces, respectively. Various contact configurations were considered by studying several lateral arrangements of the involved surfaces at the interface. Material transfer is typically possible at interfaces between the investigated clean surfaces; however, the addition of O to the Al and H to the C$_{\text{dia}}$ surfaces was found to hinder material transfer. This passivation occurs because of a significant reduction of the adhesion energy at the examined interfaces, which can be explained by the distinct bonding situations.

title: The queer sexual citizen : bisexual and queer young women’s sexual health in Tasmania
Creators: name: Grant, RF
Publisher: name: University of Tasmania

description: Over the last three decades, the intersecting rise of neoliberalism and post-­‐feminism has shifted how gender, sexuality, and citizenship are framed socially, politically, and economically in the West. At the same time, queer identities are becoming divorced  from social movement politics and are increasingly situated in individualist rhetoric of “homonormativity.” Yet, few sociological studies examine queer young women’s identity politics in the context of post-­‐feminism and homonormativity. Furthermore, bisexual and queer women’s sexual health is absent from most mainstream Australian public health research, policy, and practice. The small body of Australian scholarship in this area focuses on urban experiences, despite the well-­‐documented health disparities of rural populations.  This thesis provides an in-­‐depth, feminist sociological account of how rural Australian bisexual and queer young women negotiate identity, sex, and health. Drawing on qualitative interviews with 15 Tasmanian women, this thesis examines the following research questions:
1)	How do Tasmanian queer young women conceptualise, negotiate, and experience identity, health, and sexual citizenship in the context of neoliberal post-­‐feminism?
2)	How does heteronormativity impact Tasmanian queer young women’s experiences of “safe sex” and sexual health?
3)	What are the effects of these experiences on the health-­‐seeking behaviours and sexual health outcomes of Tasmanian queer young women?
4)	How do healthcare providers accommodate these experiences through inclusive practice?
Using Jose Esteban Muñoz’s “Disidentifications” (1999) as a theoretical framework, this thesis explores key themes of labelling sexual identity, negotiating “safe sex,” and navigating rural sexual healthcare. I argue that while queer young women’s reflexive identity and health politics are products of neoliberalism, their disidentifications offer scope for critical, queer sexual citizenship.
