Frames of mental illness and violent crime : perspectives from the courts and the media.

description: Media critics argue that mentally ill offenders are uniquely sensationalised in the press and portrayed within dominant frames of violence. The implications are the ensuing social disadvantages because the mentally ill are publicly feared as being prone to violence. What led to the motivation and scope of this thesis was a lack of analysis about the significance of a major news source regarding these offenders: the courts. A qualitative content analysis of three court cases of violent mentally ill offenders and the media representation of those cases was used as the methodological approach. Interviews with media and court representatives were conducted to obtain contextual insight to the documentary analysis. The methodological approach illustrates that media depictions of mentally ill offenders reflect and draw upon what is argued in court and how their illness is used to mitigate or reject their violent behaviour, once the case goes to court. In court, criminal responsibility for violent crimes is mitigated if an offender suffers from a psychotic-type mental illness rather than non-psychotic because the courts more commonly accept the former type of illness as mitigating violent behaviour. Consequently, media coverage of non-psychotic offenders contains more negative themes because of the way these offenders are portrayed in the courts: as ‘bad’, cold-blooded and fabricating claims of mental impairment. This thesis aims to emphasise the significance of the courts in the press coverage of violent crime and mental illness once the matter is before the courts. The author argues for a more co-operative approach between the courts and the media on issues such as court procedures, laws and decisions regarding mentally ill offenders because how such procedures are understood will influence how the media portrays these offenders. Given the media uses court proceedings as a significant news source when reporting on mentally ill offenders and the issue of ‘crime and mental illness’, it would be advantageous if the courts took a more collaborative approach with journalists to achieve a more accurate and non-stigmatising representation of this issue. The findings in this thesis will contribute to criminological and legal scholarship through detailed analysis of an under-researched and incompletely theorised area, and stimulate broader debates on the legal approach of ‘crime and mental illness’ and the significance of legal concepts on media coverage of the issue.

description: We discuss a new type of Higgs-portal dark matter (DM)-production mechanism, called bosonic-seesaw portal (BSP) scenario. The BS provides the dynamical origin of the electroweak symmetry breaking, triggered by mixing between the elementary Higgs and a composite Higgs generated by a new-color strong dynamics, hypercolor (HC). At the HC strong coupling scale, the classical-scale invariance assumed in the model is dynamically broken as well as the "chiral" symmetry present in the HC sector. In addition to the composite Higgs, HC baryons emerge to potentially be stable because of the unbroken HC baryon number symmetry. Hence the lightest HC baryon can be a DM candidate. Of interest in the present scenario is that HC pions can be as heavy as the HC baryon due to the possibly enhanced-explicit "chiral"-breaking effect triggered after the BS mechanism, so the HC baryon pair cannot annihilate into HC pions. As in the standard setup of freeze-in scenario, it is assumed that the DM was never in the thermal equilibrium, which ends up with no thermal abundance. It is then the non-thermal BSP process that crucially comes into the game below the HC scale: the HC baryon significantly couples to the standard-model Higgs via the BS mechanism, and can non-thermally be produced from the thermal plasma below the HC scale, which turns out to allow the TeV mass scale for the composite baryonic DM, much smaller than the generic bound placed in the conventional thermal freeze-out scenario, to account for the observed relic abundance. Thus the DM can closely be related to the mechanism of the electroweak symmetry breaking.

Strange gods: the crisis of meaning after Nietzsche
Creators: name: Dickson, John
Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the School of Social Sciences, Faculty of Humanities, La Trobe University, Bundoora.

This thesis centres on the paradox that ‘death of God’ prophet Friedrich Nietzsche had such a profound effect on new forms of belief in the twentieth century. The German sociologist Max Weber inherited a certain spiritual problematic from Nietzsche, which he detailed in his famous Vocation lectures at Munich University in 1918. Weber urged his audience to recognise the limits of reason in helping find the “way to true being”. Science cannot provide human fulfilment, and while religion is no longer plausible, metaphysical needs remain. This project investigates, through a series of individual case-studies, the ‘strange gods’ and new mythologies that arose as a response to the ‘Nietzsche problem’. Firstly, the young literary critic and proto-existentialist, Georg Lukács, spent the second decade of the twentieth century grubbing for roots, to use Nietzsche’s terms. Lukács, finding little to satisfy his absolutism, eventually escaped from God into politics, making a self-consciously Kierkegaardean leap of faith to join the Communist party in 1919. Secondly, the poet W.H. Auden makes the reverse trajectory: from idealistic political endeavour in the 1930s to an unexpected return to the Anglican Church of his youth in 1940. Auden’s is a highly idiosyncratic and intellectualised version of the Christian God – and his return was widely regarded by critics and audience alike as escapist. Finally, the doctrines of the founders of psychoanalysis, Sigmund Freud and C.G. Jung, are examined. While Freud only mild replacements for the “universal neurosis” of religion, Jung sought precisely the opposite for his patients: a “religious outlook” created by way of a larger mythical re-orientation. An adequate to the ‘Nietzsche’ problem remains elusive, yet each of the four protagonists offers an illuminating dead-end.

title: A architecture for MHEG objects
Creators: name: Albuquerque, Eduardo Simoes de
Publisher: name: University of Kent

description: Hypermedia applications are one of the most recent and most demanding computer uses. It is accepted that one of the main impediments to their widespread use is the lack of standards, and the lack of Open Systems with the possibility of having documents interchangeable between different hardware and software platforms. Several standards are emerging, one of which is the one being developed by the ISO/IEC WG12 known as the Multimedia and Hypermedia Information Coding Expert Group (MHEG). As desktop systems become more powerful, one of the main users of hypermedia applications is the home market. Therefore it is important to have standards and applications suitable for those platforms. This work reviews existing proposals for hypermedia architectures and interchange standards. It then assesses the suitability of the MHEG standard for use in open, distributed, and extensible hypermedia systems. An architecture for the implementa­tion of MHEG objects taking into account the limitations imposed by current desktop computers is also proposed. To assess the suitability of the proposed architecture, a prototype has been imple­mented. An analysis of the performance obtained in the prototype is presented and conclusions on the requirements for future implementations drawn. Finally, some suggestions to improve the MHEG standard are made.

description: Dirac and Weyl semimetals display a host of novel properties. In Cd$_3$As$_2$, the Dirac nodes lead to a protection mechanism that strongly suppresses backscattering in zero magnetic field, resulting in ultrahigh mobility ($\sim$ 10$^7$ cm$^2$ V$^{-1}$ s$^{-1}$). In applied magnetic field, an anomalous Nernst effect is predicted to arise from the Berry curvature associated with the Weyl nodes. We report observation of a large anomalous Nernst effect in Cd$_3$As$_2$. Both the anomalous Nernst signal and transport relaxation time $τ_{tr}$ begin to increase rapidly at $\sim$ 50 K. This suggests a close relation between the protection mechanism and the anomalous Nernst effect. In a field, the quantum oscillations of bulk states display a beating effect, suggesting that the Dirac nodes split into Weyl states, allowing the Berry curvature to be observed as an anomalous Nernst effect.

Functional characterisation of cyclase-associated protein (CAP) in Toxoplasma gondii
Creators: name: Hunt, Alex
Publisher: name: Imperial College London
Year: 2019

description: Toxoplasma gondii progression through the lytic cycle depends on a divergent actin and an array of associated unconventional myosin motors. These acto-myosin systems power mechanical processes, such as active invasion and egress of host cells, cell division and organellar trafficking. How actin-associated proteins regulate the organisation and turnover of the actin filaments to support these diverse processes is poorly understood. Cyclase-associated protein (CAP) is an actin-binding protein conserved across eukaryotes. We show that Toxoplasma CAP has a unique extension that is not present in most other Apicomplexa, giving rise to two isoforms with distinct subcellular localisations: one is localised at the parasite apex while the other is cytosolic. Here we investigated the role of CAP in Toxoplasma biology using a new generation of RH ∆ku80∆hxgprt DiCre parasites where loss of DiCre activity is prevented. Conditional knockout of CAP led to significant defects in motility, invasion, active egress, dense granule trafficking, daughter cell orientation, juxtanuclear accumulation of actin and cell-cell communication but only modest defects in synchronicity of division and no defect in replication of the apicoplast. Despite displaying phenotypes closely resembling the actin knockout, CAP is dispensable for in vitro culture. Strikingly, CAP knockout in the type I RH parasite strain does not affect in vivo virulence but results in complete attenuation of the type II Pru strain. 3D electron microscopy reveals that loss of CAP results in a defect in formation of a normal central residual body, but parasites remain connected within the vacuole. This dissociates synchronicity of division and parasite rosetting and reveals that establishment and maintenance of the residual body may be more complex than previously thought. These results highlight the different spatial requirements for F-actin dynamics in Toxoplasma that depend, in part, on CAP function.

description: We report synthesis, structural details and electrical transport properties of topological insulator Bi2Te3. The single crystalline specimens of Bi2Te3 are obtained from high temperature (950C) melt and slow cooling (2C/hour). The resultant crystals were shiny, one piece (few cm) and of bright silver color. The Bi2Te3 crystal is found to be perfect with clear [00l] alignment. The powder XRD pattern being carried out on crushed crystals showed that Bi2Te3 crystallized in R3m symmetry with a = b = 4.3866(2) A, c = 30.4978(13) A and Gamma = 120degree. The Bi position is refined to (0, 0, 0.4038 (9)) at Wyckoff position 6c and of Te are (0, 0, 0) at Wyckoff position 3a and at (0, 0, 0.2039(8)) at 6c. Ambient pressure and low temperature (down to 2K) electrical transport measurements revealed metallic behavior. Magneto transport measurements under magnetic field showed huge non saturating magneto resistance (MR) reaching up to 250% at 2.5K and under 50KOe field. Summarily, the short communication clearly demonstrates that Bi2Te3 topological insulator exhibit non-saturating large positive MR at low temperature of say below 10K. The non saturating MR is seen right up to room temperature albeit with much decreased magnitude. Worth mentioning is the fact that these crystals are bulk in nature and hence the anomalous MR is clearly an intrinsic property and not due to the size effect as reported for nano-wires or thin films of the same.

The aim of this work is to infer on the Blumenthal-Getoor index of the process X from low-frequency observations of the time-changed Levy process Y . We propose a consistent estimator for this index, derive the minimax rates of convergence and show that these rates can not be improved in general. The performance of the estimator is illustrated by numerical examples.

description: We study asymptotically minimax predictive distributions in an infinite sequence model. First, we discuss the connection between the prediction in the infinite sequence model and the prediction in the function model. Second, we construct an asymptotically minimax predictive distribution when the parameter space is a known ellipsoid. We show that the Bayesian predictive distribution based on the Gaussian prior distribution is asymptotically minimax in the ellipsoid. Third, we construct an asymptotically minimax predictive distribution for any Sobolev ellipsoid. We show that the Bayesian predictive distribution based on the product of Stein's priors is asymptotically minimax for any Sobolev ellipsoid. Finally, we present an efficient sampling method from the proposed Bayesian predictive distribution.

Mechanical performance of through thickness reinforcement for damage tolerant aircraft structurse
Creators: name: Chang, Kuan
Publisher: name: Imperial College London

description: This thesis is focused on investigating the mechanical performance of Z-pin reinforced laminate under different loading conditions and the development of automatic Z-pin insertion machines. A versatile surface-based finite element modeling strategy is developed for the analysing of cohesive contact analysis. The modeling approach is developed based on bridging law and modified Coulomb friction law. This modeling method has been validated via comparing against the benchmark work, including the Double cantilever beam test, 4-point End-Notched Flexure test, Mixed-mode Bending test. The tensile fibre failure, modeled using the Weibull Failure criterion, verified through comparing the modeling results to an experimental tensile test result of unidirectional laminate coupon. The modeling approach carried forward to the analysis of the Z-pin reinforced laminate. A three-dimensional modeling approach was used in order to address the microstructural features of Z-pinned laminates. These features, including the presence of resin pockets surrounding Z-pin, stacking sequence, Internal splitting. The interface between Z-pin and laminate, as well as internal splitting, were described by customised surface-based cohesive contact. There are a few factors that significantly affect the modeling results, including Frictional coefficient, internal splitting, mode mixities, and each of them was discussed in the parametric study section. The modeling approach was used to justify the performance of Z-pins in resisting dynamic mode I and mode II delamination has been investigated at a high loading rate. It was found that the Z-pin efficiency in resisting mode I delamination decreased with increasing loading rate compared to the quasi-static loading case, and the loading rate in the mode II test did not significantly influence the maximum bridging force. Moreover, the FE result tends to delay the shift of the failure mode from pull-out to pin rupture. An automatic Z-pin insertion machine is proposed in the last chapter.

description: The notion of fractional monodromy was introduced by Nekhoroshev, Sadovskií and Zhilinskií as a generalization of standard (`integer') monodromy in the sense of Duistermaat from torus bundles to singular torus fibrations. In the present paper we prove a general result that allows to compute fractional monodromy in various integrable Hamiltonian systems. In particular, we show that the non-triviality of fractional monodromy in 2 degrees of freedom systems with a Hamiltonian circle action is related only to the fixed points of the circle action. Our approach is based on the study of a specific notion of parallel transport along Seifert manifolds.

description: Starting with the two-band description of an orbital Feshbach resonance, we study superfluid properties of a trapped $^{173}$Yb Fermi gas under the assumptions of a local-density approximation for the trapping potential and a mean-field approximation for the intra-band Cooper pairings. In particular, we investigate the competition and interplay between the pair-breaking effect that is caused by the inter-band detuning energy, and the pair-breaking and thermal-broadening effects that are simultaneously caused by the temperature. We predict several experimental signatures that are directly caused by this interplay including a spatial separation of superfluid and normal phases within the trap, and could play decisive roles in probing two-band superfluidity in these systems.

Lattice expansion in optically excited InAs/GaAs quantum dots

description: InAs quantum dots are crystalline inclusions on the scale of few nanometers that are buried in a GaAs embedding matrix representing zero-dimensional semiconductor heterostructures. Charge carriers residing in quantum dots are strongly confined giving rise to discrete electronic energy levels similar to that of atoms. InAs quantum dots residing in a GaAs matrix do not represent independent entities, but are coupled elastically to the surrounding lattice. As a consequence of this, charge carrier-phonon interactions taking place in quantum dots have an impact on the characteristics of the crystal lattice of both dots and embedding matrix. Indeed, several experimental works performed by high-resolution continuous wave and non-linear time-resolved optical spectroscopy e. g. four-wave mixing technique have shown evidence for a broadband in the optical excitation spectra. The origin of the broadband signal was proposed to be related to a charge carrier-acoustic phonon interaction that distorted the lattice resulting in a shift of the equilibrium lattice constant. Investigating optically excited quantum dots by means of a technique that probes the crystal lattice should provide direct evidence for this effect. Based on this idea, a high-resolution XRD study on optically excited InAs/GaAs quantum dots and, serving as a reference, bulk GaAs was realized in this work. For this purpose, a liquid helium continuous flow cryostat set-up for high-resolution XRD experiments on laser irradiated samples was developed. High-resolution XRD measurements were conducted by means of a laser shutter system, which allowed to measure XRD curves of the optical active and non-active sample within a single scan, permitting the detection of relative lattice deviations with a precision on the order of 2E-6. For bulk GaAs, isotropic lattice expansion was detected that was due to laser heating of the lattice, as confirmed by comparison with calculations based on the thermal expansion coefficient of GaAs. In contrast, the InAs quantum dot sample was characterized by an anisotropic lattice expansion that extended at least 4 μm into the GaAs lattice beneath the quantum dot structure. While the determined in-plane lattice expansion was comparable to the values found for bulk GaAs, the out-of-plane expansion was significantly enhanced. This result was attributed to a polaron induced tetragonal lattice distortion that superimposed the isotropic thermal expansion.

description: We investigate the quantum thermodynamical properties of localised relativistic quantum fields, and how they can be used as quantum thermal machines. We study the efficiency and power of energy transfer between the classical gravitational degrees of freedom, such as the energy input due to the motion of boundaries or an impinging gravitational wave, and the excitations of a confined quantum field. We find that the efficiency of energy transfer depends dramatically on the input initial state of the system. Furthermore, we investigate the ability of the system to extract energy from a gravitational wave and store it in a battery. This process is inefficient in optical cavities but is significantly enhanced when employing trapped Bose Einstein condensates. We also employ standard fluctuation results to obtain the work probability distribution, which allows us to understand how the efficiency is related to the dissipation of work. Finally, we apply our techniques to a setup where an impinging gravitational wave excites the phononic modes of a Bose Einstein condensate. We find that, in this case, the percentage of energy transferred to the phonons approaches unity after a suitable amount of time. These results give a quantitative insight into the thermodynamic behaviour of relativistic quantum fields confined in cavities.

description: Das Flavorproblem beschreibt drei Generationen von Quarks und Leptonen, die zwar identische Eichkopplungen aber stark hierarchische Massen aufweisen. Diese Generationen mischen untereinander, allerdings sind die Strukturen der Mischungsmatrizen in den Quark- und Leptonsektoren sehr verschieden. Flavormodelle, die diese Probleme zu beheben versuchen, haben oft wenig eindeutige Vorhersagen und sind kaum testbar. Aus diesem Grund untersuchen wir phänomenologische Flavormodelle, die mit Beschleunigerexperimenten überprüfbar sind. Ein Neutrinomischungsmodell auf Basis der Gruppe S3 wird vorgestellt, dessen Higgs-Sektor am LHC mithilfe von exotischen Zerfällen untersucht werden kann. Weiterhin postulieren wir ein Modell auf Basis der Gruppe Δ(27), das erstmalig eine berechenbare, geometrische Phase enthält, die in allen Ordnungen stabil bleibt, und die die einzige Quelle der CP-Verletzung darstellt. Das Modell reproduziert die CKM-Daten vollständig, wobei der symmetriebrechende Sektor überprüfbare LHC-Signale enthält. Als eine Alternative zu diskreten Symmetrien untersuchen wir mithilfe eines generischen Seesaw-Modells die Konsequenzen eines Szenarios, in dem die gesamte Neutrinomischung im schweren rechtshändigen Majorana-Sektor des Modells generiert wird. Wir zeigen, dass selbst in dieser generischen Klasse von Modellen experimentelle Vorhersagen wie eine normale Neutrinohierarchie enthalten sind.
description: The flavor puzzle refers to the existence of three generations of quarks and leptons with identical gauge couplings but widely hierarchical masses. These generations mix among each other, but with very different mixing matrices in the quark and lepton sectors respectively. Flavor models used to address these issues often lack unique predictions and testability. Consequently, in this thesis we investigate phenomenological models that aim to solve parts of the flavor puzzle, but are testable using collider experiments. A neutrino mixing model based on the symmetry S3 is analyzed which contains a Higgs sector potentially testable at the LHC through exotic decays. We also propose a model based on Δ(27), which for the first time provides a calculable, geometrical phase stable up to all orders as the only source of CP violation. The model can reproduce all CKM data while having a symmetry breaking sector testable at the LHC. Finally—as an alternative to discrete symmetries—using a class of generic seesaw models we investigate the consequences of a scenario in which all the neutrino mixing is generated in a heavy right-handed Majorana sector. We show that even in the generic class of models considered, common experimental predictions such as a normal neutrino mass hierarchy emerge.

description: By considering (non-relativistic) quantum mechanics as it is done in practice in particular in condensed-matter physics, it is argued that a deterministic, unitary time evolution within a chosen Hilbert space always has a limited scope, leaving a lot of room for embedding the quantum-classical transition into our current theories without recurring to difficult-to-accept interpretations of quantum mechanics. Nonunitary projections to initial and final states, the breaking of time-reversal symmetry, a change of Hilbert space, and the introduction of classical concepts such as external potentials or localized atomic nuclei are widespread in quantum mechanical calculations. Furthermore, quantum systems require classical environments that enable the symmetry breaking that is necessary for creating the atomic configurations of molecules and crystals. This paper argues that such classical environments are provided by finite-temperature macroscopic systems in which the range of quantum correlations and entanglement is limited. This leads to classical behavior on larger scales, and to collapse-like events in all dynamical processes that become coupled to the thermalized degrees of freedom.

description: The graphical summary of multi-view scene can be readily utilized for tasks such as indoor localization. Existing methods for multi-view indoor localization consider the entire scene for localization purposes by assigning equal importance to all components/objects. In this paper, we propose a novel indoor localization method querying a graphical summary of the scene from the graphical summary of the multi-view RGB-D scenes. Salient objects have been utilized to construct the graphical summaries. The proposed method achieves the best accuracy of $0.90$ in scene localization among state-of-the-art methods.
Renormalized stress-energy tensor for stationary black holes

description: We continue the presentation of the pragmatic mode-sum regularization (PMR) method for computing the renormalized stress-energy tensor (RSET). We show in detail how to employ the $t$-splitting variant of the method, which was first presented for $\left\langleϕ^{2}\right\rangle_{ren}$, to compute the RSET in a stationary, asymptotically-flat background. This variant of the PMR method was recently used to compute the RSET for an evaporating spinning black hole. As an example for regularization, we demonstrate here the computation of the RSET for a minimally-coupled, massless scalar field on Schwarzschild background in all three vacuum states. We discuss future work and possible improvements of the regularization schemes in the PMR method.

Fabrizio de André: a popular intellectual

description: This dissertation argues that Fabrizio De André’s long-lasting popularity is the result of his role as a popular intellectual active in social criticism and engaged in public debate. I suggest that between the early 1960s and the late 1990s, De André underwent a process of artistic and personal legitimation that is crucial in the creation of an intellectual. De André has often been compared to a poet and his work is seen as an archetype of the canzone d’autore genre. While widely admired for what are considered almost unique poetic skills among singer-songwriters, he has also been adopted as a symbol of social protest. I discuss how, through his activity as a singer-songwriter, his challenging stances reached a large proportion of the Italian population – hence my definition of De André as “popular” intellectual. Through an analysis of his work, I show how his position allowed him to contribute to the continuous process of the demolition and reshaping of Italian identity and culture over a period of more than thirty years. De André, thus, illustrates how a popular culture figure can influence society by assuming the role and function of an intellectual.

description: We consider a semi-infinite spatially dispersive dielectric with unequal transverse and longitudinal susceptibilities. The effect of the boundary is characterized by arbitrary reflection coefficients for polarization waves in the material that propagate to the surface. Specific values of these coefficients correspond to various additional boundary conditions (ABC) for Maxwell's equations. We derive the electromagnetic reflection and transmission coefficients at the boundary and investigate their dependence on material parameters and ABC. We also investigate the electromagnetic zero-point and thermal spectral energy density outside the dielectric. The nonlocal response removes the boundary divergence of the spectral energy density that is present in a local model. The spectral energy density shows a large dependence on the difference between the transverse and longitudinal susceptibilities, even at distances up to 10nm from the boundary.
