description: In this paper we explore the braiding properties of the Moore-Read fractional Hall sequence, which amounts to computing the adiabatic evolution of the Hall liquid when the anyons are moved along various trajectories. In this work, the anyons are pinned to precise spatial configurations by using specific external potentials. Such external potentials break the translational symmetry and it appears that one will be forced to simulate the braidings on the entire many-body Hilbert space, an absolutely prohibitive scenario. We demonstrate how to overcome this difficulty and obtain the exact braidings for fairly large Hall systems. For this, we show that the incompressible state of a general $(k,m)$ fractional Hall sequence can be viewed as the unique zero mode of a specific Hamiltonian $H^{(k,m)}$, whose form is explicitly derived by using k-particles creation operators. The compressible Hall states corresponding to $n$$\times$$k$ anyons fixed at $w_1$,...,$w_{nk}$ are shown to be the zero modes of a pinning Hamiltonian $H^{(k,m)}_{w_1,...,w_{nk}}$, which is also explicitly derived. The zero modes of $H^{(k,m)}_{w_1,...,w_{nk}}$ are shown to be contained in the space of the zero modes of $H^{(k,m)}$. Therefore, the computation of the braidings can be done entirely within this space, which we map out for a number of Hall systems. Using this efficient computational method, we study various properties of the Moore-Read states. In particular, we give direct confirmation of their topological and non-abelian properties that were previously implied from the underlying Conformal Field Theory (CFT) structure of the Moore-Read state.

Geology of Endako Mine, British Columbia
Creators: name: Dawson, Kenneth Murray
Publisher: name: University of British Columbia

description: Endako molybdenite deposit and surrounding area were examined in detail, with particular attention to petrology and genesis of Topley Intrusions, regional structural setting and structural history of Endako orebody, sulphide and alteration mineralogy, fluid inclusion geothermometry of vein quartz, and minor element content of orebody pyrite. The host rock, Endako Quartz Monzonite, is a relatively early phase of Topley Intrusions that range in composition from diorite to granite, and in age from Middle Jurassic to Lower Cretaceous. Endako stockwork was localized by wrench faulting and doming generated by cooling of the batholith and intrusion of pre-mineral dykes. Hydrothermal fluids that altered and mineralized the stockwork were generated contemporaneously with the cooling of Endako pluton. Abundant early potassic alteration and relatively high fluid inclusion paleotemperatures attest to the paramagmatic affiliation of vein and alteration mineral assemblages. Cross-cutting relations indicate a relative age sequence among the potassic, sericitic and argillic alteration stages that is in agreement with a chemical control based primarily on the activity ratio of K+/H+. Alteration zonation suggests decreasing temperature from the ore zone towards the south, implying similar temperature variations for sulphide deposition. Fluid inclusion studies support this trend. Average minimum filling temperatures for fluid inclusions in quartz veins from potassic, sericitic and argillic assemblages are 500°C+, 480°C and 400°C, respectively. Minor element content of pyrite shows a similar temperature-dependent trend. In Q-mode factor analysis of 12-element spectrochemical data from 67 orebody pyrites, Mn, Ni and Sn define Factor I which coincides with the ore zone, whereas Factor II (Co and Cu) coincides with the pyrite zone. Correlation of Factors I and II to ore and pyrite zone respectively implies that the factors are related to mineralizing processes that give rise to the two mineralogically distinct zones.

description: For a class V of algebras, denote by Conc(V) the class of all semilattices isomorphic to the semilattice Conc(A) of all compact congruences of A, for some A in V. For classes V1 and V2 of algebras, we denote by crit(V1,V2) the smallest cardinality of a semilattice in Conc(V1) which is not in Conc(V2) if it exists, infinity otherwise. We prove a general theorem, with categorical flavor, that implies that for all finitely generated congruence-distributive varieties V1 and V2, crit(V1,V2) is either finite, or aleph_n for some natural number n, or infinity. We also find two finitely generated modular lattice varieties V1 and V2 such that crit(V1,V2)=aleph_1, thus answering a question by J. Tuma and F. Wehrung.

description: We discuss the relic problem of string gas cosmology (SGC) using gravitinos and magnetic monopoles as examples. Since SGC operates near or at the Hagedorn temperature, relics are produced copiously; in the absence of dilution, their abundances are too large. A subsequent phase of reheating can solve the gravitino problem, but fails to dilute monopoles sufficiently. We propose a subsequent phase of inflation as the most natural solution to the monopole problem; unfortunately, inflation marginalizes almost all potential achievements of SGC, with the exception of a possible explanation of the dichotomy of space (why did only three dimensions inflate?).

description: In this paper we provide a wildness criterion for any finite dimensional Hopf algebra with finitely generated cohomology. This generalizes a result of Farnsteiner to not necessarily cocommutative Hopf algebras over ground fields of arbitrary characteristic. Our proof uses the theory of support varieties for modules, one of the crucial ingredients being a tensor product property for some special modules. As an application we prove a conjecture of Cibils stating that small quantum groups of rank at least two are wild.

description: We investigate the possibility of observing very small amplitude low frequency solar oscillations with the proposed laser interferometer space antenna (LISA). For frequencies $ν$ below $3\times 10^{-4} {\rm Hz}$ the dominant contribution is from the near zone time dependent gravitational quadrupole moments associated with the normal modes of oscillation. For frequencies $ν$ above $ 3\times 10^{-4} {\rm Hz}$ the dominant contribution is from gravitational radiation generated by the quadrupole oscillations which is larger than the Newtonian signal by a factor of the order $(2 πr ν/ c)^4$, where $r$ is the distance to the Sun, and $c$ is the velocity of light. The low order solar quadrupole pressure and gravity oscillation modes have not yet been detected above the solar background by helioseismic velocity and intensity measurements. We show that for frequencies $ν\lesssim 2\times 10^{-4} {\rm Hz}$, the signal due to solar oscillations will have a higher signal to noise ratio in a LISA type space interferometer than in helioseismology measurements. Our estimates of the amplitudes needed to give a detectable signal on a LISA type space laser interferometer imply surface velocity amplitudes on the sun of the order of 1-10 mm/sec in the frequency range $1\times 10^{-4} -5\times 10^{-4} {\rm Hz}$. If such modes exist with frequencies and amplitudes in this range they could be detected with a LISA type laser interferometer.

Gambling in Elizabethan England : perspectives on England's 'Lotterie Generall' of 1567‚Äö-69
Creators: name: Ball, PS
Publisher: name: University Of Tasmania
Year: 2023

description: This study concerns Elizabeth I's attempt to establish a state lottery as a means of 'voluntary taxation'. The outcome was unhappy. Under one twelfth of the 400,000 tickets sold, with drastic measures required to achieve even so much. The sales period was extended greatly and people coerced into taking part; to avoid making a loss the organisers ultimately found it necessary to diminish every prize to one twelfth its original value. The thesis approaches the lottery from several angles. Its early chapters treat the scheme as a single, big event, contextualising it against the history of English gambling and evolution of European lotteries. Within this broader setting, socio-cultural and political contributors to the failure are explored. Later chapters involve closer scrutiny of specific participants and tickets, informed by methodologies such as quantitative history, microhistory and prosopography. Several factors make this possible. The printed lists of prizewinning tickets have partly survived, preserving details of around four thousand purchases. Participants were expected to devise posies for their tickets: short sayings or rhymes, original or quotation, to be read publicly when each ticket was drawn. This offered those buying under duress an avenue for complaint. Moreover, a high proportion of them were social elites. Not only can such individuals be identified, further details about them can be located. This enables their posies to be interpreted in context, rather than taken literally: sarcasm, equivocation, double meanings, etc. become visible, suggesting political undercurrents not immediately apparent. The late 1560s involved tension, abroad and domestically. The lottery coincided closely with Mary Stewart's materialisation in England. The thesis contends that an awareness of her presence helps make sense of certain posies, while the tickets may preserve evidence of early reactions to her appearance.

description: We present a new formalism for finding the low-energy effective Lagrangian of Goldstinos and other fields. This Lagrangian is written using standard superspace and the superfields are constrained to include only the light degrees of freedom. The Goldstino resides in a (constrained) chiral superfield X which is naturally identified at short distances. This allows us to exactly compute the IR behavior of some correlation functions even in strongly coupled theories with SUSY breaking. The Goldstino couplings above the scale of the matter superpartners are determined by identifying X with the standard spurion. At energies below the superpartners' scale, fermions, scalars (including Goldstone bosons) and gauge fields are also described by constrained superfields. Our framework makes it easy to find the leading order terms in the Lagrangian and to control their corrections. It simplifies the derivation of many known results and leads to new ones.

description: Is the turbulence in cluster-forming regions internally driven by stellar outflows or the consequence of a large-scale turbulent cascade? We address this question by studying the turbulent energy spectrum in NGC 1333. Using synthetic 13CO maps computed with a snapshot of a supersonic turbulence simulation, we show that the VCS method of Lazarian and Pogosyan provides an accurate estimate of the turbulent energy spectrum. We then apply this method to the 13CO map of NGC 1333 from the COMPLETE database. We find the turbulent energy spectrum is a power law, E(k) k^-beta, in the range of scales 0.06 pc < ell < 1.5 pc, with slope beta=1.85\pm 0.04. The estimated energy injection scale of stellar outflows in NGC 1333 is ell_inj 0.3 pc, well resolved by the observations. There is no evidence of the flattening of the energy spectrum above the scale ell_inj predicted by outflow-driven simulations and analytical models. The power spectrum of integrated intensity is also a nearly perfect power law in the range of scales 0.16 pc < ell < 7.9 pc, with no feature above ell_inj. We conclude that the observed turbulence in NGC 1333 does not appear to be driven primarily by stellar outflows.

description: At present, dwarf spheroidal galaxies satellites of the Milky Way may represent the best astrophysical objects for dark matter (DM) searches with gamma-ray telescopes. They present the highest mass-to-light ratios known in the Universe. Furthermore, many of them are near enough from the Earth to be able to yield high predicted DM annihilation fluxes that might be observed by current gamma-ray instruments like MAGIC. The picture has become even better with the recent discovery of new dwarfs. These new objects are expected to yield even higher DM annihilation fluxes, since most of them are nearer than the previously known dwarfs and are even more DM dominated systems. Here a tentative list of the best candidates is given. The observational results obtained with MAGIC from the Draco dwarf as well as the observation of other dwarfs carried out by other Cherenkov telescopes are presented as well. Finally, we discuss the detection prospects of such kind of objects in the context of DM searches.

Mrs Henry Dobson : Victorian 'do - gooder' or sincere social reformer : an analysis of her charitable and public welfare work in the 1890's
Creators: name: Taylor, AR
Publisher: name: University Of Tasmania

description: When Mrs Henry Dobson died on the fifth of June 1934 at the age of 91, a lifetime of devoted and continual service to Tasmanian public and social welfare work came to a close. For more than fifty years Mrs Dobson had supported a wide range of philanthropic and public causes, and there were very few she did not help, either financially or with personal assistance, at some time or other. Not only was she President of the Free Kindergarten Association, the Women's Committee of the Blind, Deaf and Dumb Children 's Society and the Ministering Children's League, but she was also the Vice-President of the Tasmanian Branch of the League of Nations Union, the Victoria League of Tasmania, the Child Welfare Association, the Women's Christian Temperance Union and the Art Society. Apart from these positions of honour, she was also the founder of the Victoria Convalescent Home, the Women's Health Association, the Lyceum Club, the Tasmanian Sanatorium for Consumptives and the Tasmanian Alliance Francaise. She was the first State Commissioner for the Girl Guides, the Life Patroness of the Bush Nursing Organization and the Australian representative, as appointed by Alfred Deacon, to the International Women's Suffrage Convention. In addition, Mrs Dobson devoted the last thirty years of her life to supporting the National Council of Women, of which she was the Tasmanian and Australian President and an International Vice President and Life Member. Her activity in the majority of these organizations falls outside the period with which this dissertation will be primarily concerned. However, her association, in the 1890 's, with the National Council of Women, the Women's Christian Temperance Union, the Ministering Children's League, the Blind, Deaf and Dumb Society, and the Victoria Convalescent Home, will come under discussion, along with her activities in several other organizations not mentioned in her obituary, the most notable being the Women's Sanitary association, the Village Settlement Committee, the Brabazon Society and the Union Jack association. Aside from her extensive activities in these dozens of organizations, she also found time to spend ten years of her life at sea, making thirty-three trips to Britain and Europe and sixty seven trips away from the state. To illustrate the remarkable energy of this woman one must mention the fact that her last trip to Britain was made in 1933 at the grand old age of ninety!

description: \ion{Ca}{2} H emission is a well-known indicator of magnetic activity in the Sun and other stars. It is also viewed as an important signature of chromospheric heating. However, the \ion{Ca}{2} H line has not been used as a diagnostic of magnetic flux emergence from the solar interior. Here we report on Hinode observations of chromospheric \ion{Ca}{2} H brightenings associated with a repeated, small-scale flux emergence event. We describe this process and investigate the evolution of the magnetic flux, G-band brightness, and \ion{Ca}{2} H intensity in the emerging region. Our results suggest that energy is released in the chromosphere as a consequence of interactions between the emerging flux and the pre-existing magnetic field, in agreement with recent 3D numerical simulations.

description: While it is well known that neutrinos are emitted from standard core collapse protoneutron star supernovae, less attention has been focused on neutrinos from accretion disks. These disks occur in some supernovae (i.e. "collapsars") as well as in compact object mergers, and they emit neutrinos with similar properties to those from protoneutron star supernovae. These disks and their neutrinos play an important role in our understanding of gamma ray bursts as well as the nucleosynthesis they produce. We study a disk that forms in the merger of a black hole and a neutron star and examine the neutrino fluxes, luminosities and neutrino surfaces for the disk. We also estimate the number of events that would be registered in current and proposed supernova neutrino detectors if such an event were to occur in the Galaxy.

description: This report describes the recent efforts to compute analytic formulae for the Next-to-Leading-Order (NLO) QCD corrections to Higgs plus two jet production at hadron colliders. In these calculations the Higgs boson couples to gluons via a top-quark loop which is integrated out to form an effective vertex. The amplitudes are further simplified by splitting the real Higgs scalar into the sum of two complex scalars phi and phi^dagger. Four-dimensional unitarity is used to construct the cut-containing pieces of the amplitude, while a variety of bootstrap and Feynman diagram techniques are used to construct the rational pieces. The results described here are valid in the limit of a large top quark mass and when the transverse momenta of the jets are less than mt.

Metacognition for well-learned information
Creators: name: Kucina, TM
Publisher: name: University Of Tasmania
Year: 2023

description: The current study investigated the effects of criterion learning and lag on metacognitive accuracy and memory performance. Forty-six participants (27 female) aged between 18-63 years studied lists of Lithuanian-English word pairs presented in either groups of nine (short lag) or 36 items (long lag). Participants engaged in practice testing for the items until they were correctly recalled one, three, or nine times. Participants made judgments of learning regarding the likelihood they would remember the item in about 7 days, where they would engage in a cued recall task. Judgements were recorded on either binary or continuous scales. Absolute accuracy was greater for the long lag compared to short lag (p < .001), which led to substantial overconfidence in the short lag (p < .001). Relative accuracy was superior in the long lag compared to the short lag (p < .001). Final cued recall performance was higher in the long lag and as criterion increased. These findings suggest students' memory performance will benefit from the repeated successful recall of information. Crucially, if students employ a longer lag, not only will their memory be enhanced but they will likely display superior metacognitive monitoring of their learning.

description: Electrons most often organize into Fermi-liquid states in which electron-electron interactions play an inessential role. A well known exception is the case of one-dimensional (1D) electron systems (1DES). In 1D the electron Fermi-surface consists of points, and divergences associated with low-energy particle-hole excitations abound when electron-electron interactions are described perturbatively. In higher space dimensions, the corresponding divergences occur only when Fermi lines or surfaces satisfy idealized nesting conditions. In this article we discuss electron-electron interactions in 2D graphene bilayer systems which behave in many ways as if they were one-dimensional, because they have Fermi points instead of Fermi lines and because their particle-hole energies have a quadratic dispersion which compensates for the difference between 1D and 2D phase space. We conclude, on the basis of a perturbative RG calculation similar to that commonly employed in 1D systems, that interactions in neutral graphene bilayers can drive the system into a strong-coupling broken symmetry state with layer-pseudospin ferromagnetism and an energy gap.

description: The thermal pairwise entanglement (TE) of the S=1/2 XY chain in a transverse magnetic field is exactly resolved by means of the Jordan-Wigner transformation. It is found that the TE vanishes at a common temperature Tc~0.4843J, which is irrelevant to the field. A thermal quantity is proposed to witness the entangled state. Furthermore, the TE of the S=1/2 antiferromagnetic-ferromagnetic (AF-F) Heisenberg chain is studied by the transfer-matrix renormalization group method.The TEs of the spins coupled by AF and F interactions are found to behave distinctively. The vanishing temperature of the field-induced TE of the spins coupled by F interactions is observed to change with the magnetic field. The results are further confirmed and analyzed by the mean-field theory.

Structure and metamorphism of Penfold Creek area, near Quesnel Lake, central British Columbia
Creators: name: Fletcher, Christopher John Nield
Publisher: name: University of British Columbia
Year: 2011

description: The Quesnel Lake area lies within the Omineca Crystalline Belt, and is underlain by the northern extremity of the Shuswap Metamorphic Complex. Closely spaced and steeply dipping isograds mark the margins of the metamorphic belt. In the Penfold Creek area only one and a half miles separate the biotite and sillimanite isograds. Related to this sharp increase in metamorphic grade there is a marked change in the fold style from similar folds, showing a strong axial-plane cleavage, in the chlorite zone to tight refolded isoclines in the sillimanite zone. Three periods of deformation and two periods of prograde metamorphism have been recognized, with the first metamorphic period being associated with Phase 2 deformation and the second being post Phase 2. Mineralogical changes in pelitic and calcareous assemblages suggest that the increase in metamorphic grade was a function of both temperature and composition of the fluid phase, and that total pressure remained relatively constant. Compositional variations of major minerals in the pelitic rocks are consistent with a model of increasing P[sub H₂O] with increasing temperature, moreover they suggest that in the highest grades of meta-morphism P[sub H₂O] = P[sub Total]. An isoclinally folded granitic gneiss crops out along the shores of Quesnel Lake. It is believed to represent a metamorphosed granite sill which had been intruded into the surrounding Proterozoic sediments.

Actions speak louder than words : the production and enactment effects on recall and recognition memory of verbs
Creators: name: Blowfield, HL
Publisher: name: University Of Tasmania
Year: 2023

description: This study aimed to investigate the effects of gestural and verbal production of single verbs on memory and expected to find that the physical embodiment of verbs via miming would significantly increase memory retention. It was also expected that gesturing verbs while speaking them aloud would lead to significantly more produced verbs being remembered than when they were only gestured. 12 participants (6 female; 1 left-handed) aged 18-27 were recruited from the University of Tasmania and via snowball sampling and were randomly assigned to either the gesture only group, or the gesture/spoken group, where they studied 80 verbs coloured blue or white which indicated whether to produce or silently read the words. Contrary to what was expected, there were no significant between subject effects, suggesting no benefit to vocalising verbs whilst performing them as gestures. However, there were extremely large within subject effects, suggesting that mimed performance of verbs significantly increases memory. These results suggest that the enactment of verbs leads to significant memory benefit, while the addition of speaking aloud verbs may not lead to any additional effect. However, further investigation is necessary to address the study's limitations.

description: Neutron diffraction measurements have been carried out to investigate the magnetic form factor of the parent SrFe2As2 system of the iron-based superconductors. The general feature is that the form factor is approximately isotropic in wave vector, indicating that multiple d-orbitals of the iron atoms are occupied as expected based on band theory. Inversion of the diffraction data suggests that there is some elongation of the spin density toward the As atoms. We have also extended the diffraction measurements to investigate a possible jump in the c-axis lattice parameter at the structural phase transition, but find no detectable change within the experimental uncertainties.
Theory of superconducting and magnetic proximity effect in S$\mid$F structures with inhomogeneous magnetization textures and spin-active interfaces

description: We present a study of the proximity effect and the inverse proximity effect in a superconductor$\mid$ferromagnet bilayer, taking into account several important factors which mostly have been ignored in the literature so far. These include spin-dependent interfacial phase shifts (spin-DIPS) and inhomogeneous textures of the magnetization in the ferromagnetic layer, both of which are expected to be present in real experimental samples. Our approach is numerical, allowing us to access the full proximity effect regime. In Part I of this work, we study the superconducting proximity effect and the resulting local density of states in an inhomogeneous ferromagnet with a non-trivial magnetic texture. Our two main results in Part I are a study of how Bloch and Néel domain walls affect the proximity-induced superconducting correlations and a study of the superconducting proximity effect in a conical ferromagnet. The latter topic should be relevant for the ferromagnet Ho, which was recently used in an experiment to demonstrate the possibility to generate and sustain long-range triplet superconducting correlations. In Part II of this work, we investigate the inverse proximity effect with emphasis on the induced magnetization in the superconducting region as a result of the "leakage" from the ferromagnetic region. It is shown that the presence of spin-DIPS modify conclusions obtained previously in the literature with regard to the induced magnetization in the superconducting region. In particular, we find that the spin-DIPS can trigger an anti-screening effect of the magnetization, leading to an induced magnetization in the superconducting region with \textit{the same sign} as in the proximity ferromagnet.

description: The dynamics of the 2D Potts ferromagnet when quenched below the transition temperature is investigated in the case of discontinuous phase transition, which is interesting for understandingthe non equilibrium dynamics of systems with many competing equivalent low temperature phases, that appears to be not much explored. After briefly reviewing some recent findings, we focus on the numerical study of quenches just below the transition temperature on square lattices. We show that, up to a certain time, metastable states can be observed for which energy stays constant above the equilibrium energy and the self-correlation function displays a fast decay.

The influence of genetic, environmental and racial defendant characteristics on criminal trial outcomes
Creators: name: Brighella, IE
Publisher: name: University Of Tasmania
Year: 2023

description: There is emerging evidence that aggression and antisocial behaviour may be influenced by the interplay between the low activity Monoamine Oxidase A (MAOA) genotype and history of childhood maltreatment exposure. Establishment of the genetic and environmental determinants of aggressive, antisocial behaviour has resulted in the court application of behavioural genetics evidence to achieve exculpation or leniency in the defendant's criminal sentence. However, this is yet to be explored in the context of racial differences. The present research aimed to build upon existing literature concerning the efficacy of the application of behavioural genetics evidence in court, by examining the cumulative influence of a defendant's genetics, environmental trauma and race on judiciary sentencing decisions. A total of 145 participants (118 female, 27 male), with ages ranging from 19-67 years, were randomly allocated to one of eight vignettes, where in which explanations concerning the defendant's genetics, childhood maltreatment and race were manipulated. Participants completed questions relating to their perceptions of defendant criminal culpability and appropriate sentence severity, and a self-report questionnaire to assess their attitudes towards modern genomics (PUGGS; Carver et al., 2017). Findings demonstrated no interaction between MAOA genetic, environmental trauma and Indigeneity status defendant characteristics on judicial culpability and sentence severity determinations. However, there was a modest effect on MAOA genetic evidence on judicial prison length decisions. This research is the first of its kind in an Australian population and contributes meaningful results to a growing field.

The targum (1943:Feb. 5 - 1943:Feb. 26)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1943

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
No influence of background music on face recognition

description: Identifying methods to improve recognition memory for faces is valuable in a number of clinical and non-clinical applied situations. We investigated whether background music can improve face recognition through context reinstatement and the temporal parameters of this potential effect. We predicted that through multisensory processing of visual item information (a face) with rich auditory contextual information (music) a memory ensemble would form, thus creating an effective mnemonic cue. Participants were 19 females and 10 males, ranging in age from 19 to 47 years (Mage = 26 years, SD= 8). Participants were asked to remember faces in a study session with and without background music, then their memory was tested via a recognition test presented with the same music or with no music. Contrary to our predictions, we found no significant reinstatement-recognition benefits: There was no evidence to suggest that reinstating the musical encoding context at the face recognition test improved participants' ability to discern between previously seen and unseen faces. Future research needs to address the challenges specific to context-recognition memory and examine the boundary conditions that might lead to improvements in face recognition.
Phase transitions in self-gravitating systems and bacterial populations with a screened attractive potential

description: We consider a system of particles interacting via a screened Newtonian potential and study phase transitions between homogeneous and inhomogeneous states in the microcanonical and canonical ensembles. Like for other systems with long-range interactions, we obtain a great diversity of microcanonical and canonical phase transitions depending on the dimension of space and on the importance of the screening length. We also consider a system of particles in Newtonian interaction in the presence of a ``neutralizing background''. By a proper interpretation of the parameters, our study describes (i) self-gravitating systems in a cosmological setting, and (ii) chemotaxis of bacterial populations in the original Keller-Segel model.
Mount Wellington and the sense of place
Creators: name: Barnes, A
Publisher: name: University Of Tasmania
Year: 2023

description: Mount Wellington is a major feature of the topography of Hobart and the surrounding area. This study was undertaken to describe the significance of Mount Wellington using a phenomenological approach. As part of everyday living, people obviously and unavoidably develop relationships with places. The nature of these relationships, the essential qualities of place and the sense of place were described with reference to phenomenological studies of place. It was suggested that people form emotional bonds with places that are important for both the individual and for society as a whole. The history of mountains indicates that they have been important places, often engendering a sense of reverence and providing spiritual replenishment. The significance of mountains in general was described with reference to Martin Heidegger's writings. Mountains most obviously reflect Heidegger's notion of 'the fourfold' and by 'thinking like a mountain', they may manifest 'Being'. The significance of Mount Wellington was investigated with reference to its physical setting, the activities pursued on it and its more general meanings: the essential qualities of a place. Some artistic depictions of Mount Wellington's various poses were described. Early portrayals tended to focus on topographical idealism whilst later depictions often sought to emphasise the deeper meanings that Mount Wellington engenders. The many activities that people have pursued on Mount Wellington presented a diversity of relationships that people have developed with it. It was suggested that certain activities are more conducive to sensing the essence of Mount Wellington whilst the pursuit of others ignores this essence. The deeper meanings of Mount Wellington were described and it was noted that Mount Wellington has great significance for Hobartians. These meanings become apparent through authentic dwelling.
