description: We studied the unusual Quantum Hall Effect (QHE) near the charge neutrality point (CNP) in high-mobility graphene sample for magnetic fields up to 18 T. We observe breakdown of the delocalized QHE transport and strong increase in resistivities $ρ_{xx},|ρ_{xy}|$ with decreasing Landau level filling for $ν< 2$, where we identify two insulating regimes. For $1 \gtrsim |ν| \gtrsim 1/2$ we find an exponential increase of $ρ_{xx,xy} \sim e^{a(H-H_c)}$ within the range up to several resistance quanta $R_K$, while the Hall effect gradually disappears, consistent with the Hall insulator (HI) with local transport. Then, at $ν\approx 1/2$ a cusp in $ρ_{xx}(H)$ followed by an onset of even faster growth indicates transition to a collective insulator (CI) state. The likely candidate for this state is a pinned Wigner crystal.

Beliefs in science and the effects on support for pro-environmental policies
Creators: name: Hughes, JE
Publisher: name: University Of Tasmania
Year: 2023

description: Public beliefs about climate change do not align with the consensus among scientists (Cook & Lewandowsky, 2016). One of the reasons this may occur is that individuals with more conservative worldviews can become less accepting of facts about climate change as scientific literacy increases (Kahan et al., 2012). The present study extended on previous research by Drummond, Palmer, and Sauer (2016) to investigate whether positive attitudes towards science, specifically Endorsement of Scientific Inquiry (ESI), help individuals to evaluate information more accurately. It was hypothesised that higher levels of ESI would be associated with increases in the difference in ratings for pro-environmental policies that were supported by stronger or weaker evidence, and these effects would be independent of worldview. A total of 503 participants (265 female; aged 18 to 69 years, M = 34.30, SD = 12.17) rated support for 16 pro-environmental policies, and were measured on ESI (Drummond et al., 2016), scientific literacy (Drummond et al., 2016), and worldview (Kahan et al., 2012). The hypothesis was supported, such that as ESI increased, the difference in ratings for weak and strong evidence policies also increased, and this was independent of worldview, b = -0.78 [-0.97, -0.60], t(501) = -8.28, p < .001. Unlike ESI, the moderating effect of scientific literacy was influenced by worldview. The findings offered support for the view that individuals with higher ESI may have an improved ability to discern and reason with scientific information. This suggests public support for pro-environmental policies may be expedited through strategies to increase ESI.
Therapeutic-like effects of trace amine-associated receptor 1 (TAAR1) activation in models of alcohol abuse
Creators: name: James, FLJ
Publisher: name: University Of Tasmania
Year: 2023

description: Alcohol use disorders (AUD) are one of the most common and devastating forms of drug addiction in Australia. However, current treatments are severely lacking in effective pharmacological options. In recent years, the trace-amine associated receptor 1 (TAAR1) has been identified as a potential target for new pharmacological interventions in drug addiction, showing effectiveness in reducing cocaine- and methamphetamine-addiction related behaviours in animal models. However, the effects of TAAR1 activation on alcohol addiction have not been addressed. This study aimed to examine the potential therapeutic effects of TAAR1 activation with the partial agonist, RO5263397, on alcohol self-administration and locomotor sensitisation behaviours in a rodent model of alcohol addiction. The data showed that TAAR1-activation resulted in a significant decrease of ethanol consumption in g/kg in the first hour of the self-administration test, and a significant decrease in locomotor activity. However, there was no effect on ethanol consumption in mL or preference. Furthermore, TAAR1 activation was also found to significantly reduce sucrose and water consumption (mL) which was unexpected. These findings provide an important first look at the effects of TAAR1 activation on alcohol addiction and provide a strong direction for future studies in this area.

description: We report on the first experimental verification of the Zurek-Kibble scenario in an isolated superconducting ring over a wide parameter range. The probability of creating a single flux quantum spontaneously during the fast normal-superconducting phase transition of a wide Nb loop clearly follows an allometric dependence on the quenching time $τ_{Q}$, as one would expect if the transition took place as fast as causality permits. However, the observed Zurek-Kibble scaling exponent $σ= 0.62\pm0.15$ is two times larger than anticipated for large loops. Assuming Gaussian winding number densities we show that this doubling is well-founded for small annuli.

description: The malaise of electronic spam mail that solicit illicit partnership using bogus business proposals (popularly called 419 mails) remained unabated on the internet despite concerted efforts. In addition to these are the emergence and prevalence of phishing scams that use social engineering tactics to obtain online access codes such as credit card number, ATM pin numbers, bank account details, social security number and other personal information (22). In an age where dependence on electronic transaction is on the increase, the web security community will have to devise more pragmatic measures to make the cyberspace safe from these demeaning ills. Understanding the perpetrators of internet crimes and their mode of operation is a basis for any meaningful effort towards stemming these crimes. This paper discusses the nature of the criminals engaged in fraudulent cyberspace activities with special emphasis on the Nigeria 419 scam mails. Based on a qualitative analysis and experiments to trace the source of electronic spam and phishing emails received over a six months period, we provide information about the scammers personalities, motivation, methodologies and victims. We posited that popular email clients are deficient in the provision of effective mechanisms that can aid users in identifying fraud mails and protect them against phishing attacks. We demonstrate, using state of the art techniques, how users can detect and avoid fraudulent emails and conclude by making appropriate recommendations based on our findings.

title: Nineteenth Century English Choral Music
Creators: name: Parker, Ann Boley
Publisher: name: Old Dominion University Libraries
Year: 1984

description: English music history in the nineteenth century illuminates the larger society of which it was part. Music had lost nearly all of its importance to the English people in the early nineteenth century. This was drastically changed when the sight-singing movement took hold in the early 184Os. It spread rapidly and became a social influence as well as a musical one. People gathered together to learn to read music and then formed choirs in order to perform. Singing societies were organized to serve a variety of purposes, from providing religious outlets to convivial evenings. The societies often bridged wide gaps between social stratas. Mammoth choral festivals were held both in London and in the provinces and choirs became an important part of the Anglican services. By the end of the century the choral movement had helped England to become an important musical nation.
You're a wizard, Ari : bias due to rewards in binary decision-making
Creators: name: Jurasovic, EM
Publisher: name: University Of Tasmania
Year: 2023

description: We investigated the effect of the factors Reward Type (points vs. money) and Reward Schedule (constant vs. variable) on bias in a computerised binary decision-making task. Participants (19 female; N = 32) were aged 18 to 41 years were asked to identify which colour was in majority in a two-colour visual discrimination task embedded in a computer game. We measured reaction times, accuracy and proportion of bias congruent responses as manifestations of bias in participants' decision-making. An exact binomial test indicated that participants chose the option providing on average larger rewards at a rate greater than chance (p < .001). However linear mixed modelling and model selection provided minimal evidence to indicate that this bias was due to either Reward Type or Reward Schedule. Bias was greater when participants were told a priori about the likelihood of trial occurrences compared to being rewarded for correct trials (p < .001). Future research may test the effect of different reward sizes and true vs. random scoring on bias in the current context. In keeping with the scientific principles of honesty and collaboration, all analysis scripts, raw data, preliminary study plans and final manuscript are available online at the Open Science Framework website.

description: We investigate the ground-state properties of the one-dimensional two-band Hubbard model with different bandwidths. The density-matrix renormalization group method is applied to calculate the averaged electron occupancies $n$ as a function of the chemical potential $μ$. Both at quarter and half fillings, "charge plateaux" appear in the $n$-$μ$ plot, where $dμ/dn$ diverges and the Mott insulating states are realized. To see how the orbital polarization in the one-quarter charge plateau develops, we apply the second-order perturbation theory from the strong-coupling limit at quarter filling. The resultant Kugel-Khomskii spin-orbital model includes a $magnetic$ field coupled to orbital pseudo-spins. This field originates from the discrepancy between the two bandwidths and leads to a finite orbital pseudo-spin magnetization.

description: We construct a class of Lie 3-algebras with an arbitrary number of pairs of generators with Lorentzian signature metric. Some examples are given and corresponding BLG models are studied. We show that such a system in general describes a supersymmetric massive vector multiplets after the ghost fields are Higgsed. Simple systems with nontrivial interaction are realized by infinite dimensional Lie 3-algebras associated with the loop algebras. The massive fields are then naturally identified with the Kaluza-Klein modes by the toroidal compactification triggered by the ghost fields. For example, Dp-brane with an (infinite dimensional) affine Lie algebra symmetry $\hat g$ can be identified with D(p+1)-brane with gauge symmetry $g$.

System for the automatic sensing and recording of a greenhouse environment using moving sensors
Creators: name: Von Beckmann, Joerg Walter
Publisher: name: University of British Columbia
Year: 2011

description: One of the major problems encountered in collecting data for use in analysing the internal environment of a greenhouse is the time required to read and record the many environmental parameters. This problem severely restricts the analysis of factors affecting the environment by limiting the number of locations that can be conveniently sampled and the frequency with which each location can be sampled. The time and cost factors also limit the number of parameters which can be measured at each location. A sensor module has been developed which will automatically measure environmental parameters at any number of pre-determined points along a fixed track. The module is capable of sampling 15 variables at a single location and transmitting via one cable all 15 signals for interpretation by a main decoding and recording station. The module is capable of automatically making 10 stops and measuring 15 parameters at each stop in about 10 minutes; a task which is very time consuming or expensive by other methods.
Religious institutions, social change, symbols and same-sex marriage
Creators: name: Boland, JA
Publisher: name: University Of Tasmania
Year: 2023

description: Previous studies of religious institutions, social change and pluralism have adhered to the conventional sociological dichotomy between the individual and structure. In studies involving LGBTIQ+ issues and religious organisations, primarily from the United States, the celebration of individual agency over structural determinants predominates. This literature also suggests religious institutions be seen as structurally inert, unresponsive or deliberately reactionary when participating in public debates about controversial social changes. This thesis attempts to overcome this image by arguing that contemporary religious institutions dialogically mediate social change through condensing symbols‚ÄövÑvp. Through church magazines, secular newspapers, public letters and historical documents, institutional elites propagate a discursive understanding of how organisations adapt to change. The thesis' three case studies provide examples of how the Church of Jesus Christ of Latter-Day Saints, Anglican Archdiocese of Sydney and the liberal Religious Society of Friends have engaged the public through controversial debates, such as same-sex marriage, to discursively negotiate, respond and resist pluralism. How an institution develops and deploys condensing symbols‚ÄövÑvp allows us to tackle the broader sociological issue of how religious institutions structurally adapt, through these symbolic mediators, to change.

Exploring the power of the augmented soft and hard ecotourism spectrum to segment walkers on the Overland Track, Tasmania
Creators: name: Yamasaki, M
Publisher: name: University Of Tasmania
Year: 2023

description: The focus of the study is the Ecotourist Spectrum devised by Weaver and Lawton in 2001. The Spectrum was the first to suggest that ecotourists display a range of hard to soft characteristics and has become an accepted part of the literature on ecotourism. Yet, a detailed examination of the literature found that this behaviour-based Spectrum produced only a limited distinction between ecotourists, while other studies suggested the potential to incorporate values into the Spectrum to provide a more detailed segmentation of ecotourists (Blamey & Braithwaite, 1997, Zografos & Allcroft, 2007). Weaver and Lawton's original Spectrum was augmented by adding values and the modified range of variables were tested by applying the new spectrum to the ecotourism experience of the Overland Track, a multi-day walk in Tasmania. This study employed Q methodology, which according to Robbins and Kruger (2000) is the scientific study of subjectivity. The data were collected in two phases; phase one comprised of 60 interviews with respondents that had recently completed the Overland Track walk. Their responses shaped the wording of the Q method statements that phase two interviewees were asked to sort. The statements were based on the nine behavioural criteria derived from Weaver and Lawton's Spectrum plus three additional emergent criteria on values generated from phase one data. In phase two, 54 individual respondents that were at the end of their walk (or were on the Track) agreed to sort 36 statements on a distribution scale and be interviewed to explain their choices. The transcribed interviews were correlated and factor analysed using PQ Method. The study identified five distinctive groups of ecotourists with each of the groups containing walkers who displayed a combination of soft and hard ecotourist characteristics. The absence of purely soft or hard ecotourists in this study suggests that Weaver and Lawton's Ecotourist Spectrum lacks the sophistication to effectively segment ecotourists on the Overland Track. In addition, the incorporation of the statements on values proved effective in detecting the five groups of ecotourists. This study proposes a spectrum of ecotourists who participate in multi-day walks that offers a finer grained understanding of ecotourist market segments. The study also recommends that future research is conducted to test the developed spectrum in additional ecotourism contexts.

description: Determinations of structure functions and parton distribution functions have been recently obtained using Monte Carlo methods and neural networks as universal, unbiased interpolants for the unknown functional dependence. In this work the same methods are applied to obtain a parametrization of polarized Deep Inelastic Scattering (DIS) structure functions. The Monte Carlo approach provides a bias--free determination of the probability measure in the space of structure functions, while retaining all the information on experimental errors and correlations. In particular the error on the data is propagated into an error on the structure functions that has a clear statistical meaning. We present the application of this method to the parametrization from polarized DIS data of the photon asymmetries $A_1^p$ and $A_1^d$ from which we determine the structure functions $g_1^p(x,Q^2)$ and $g_1^d(x,Q^2)$, and discuss the possibility to extract physical parameters from these parametrizations. This work can be used as a starting point for the determination of polarized parton distributions.

description: Together with spaces of constant sectional curvature and products of a real line with a manifold of constant curvature, the socalled Egorov spaces and $\varepsilon$-spaces exhaust the class of $n$-dimensional Lorentzian manifolds admitting a group of isometries of dimension at least ${1/2} n(n-1)+1$, for almost all values of $n$ [Patrangenaru V., Geom. Dedicata 102 (2003), 25-33]. We shall prove that the curvature tensor of these spaces satisfy several interesting algebraic properties. In particular, we will show that Egorov spaces are Ivanov-Petrova manifolds, curvature-Ricci commuting (indeed, semi-symmetric) and $\mathcal P$-spaces, and that $\varepsilon$-spaces are Ivanov-Petrova and curvature-curvature commuting manifolds.
Beyond the bases : the status of territorial sovereignty in the Australian Antarctic Territory
Creators: name: Hodgson-Johnston, Indiah
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis critically examines two aspects of international law related to Australia's territorial sovereignty over the Australian Antarctic Territory (the AAT): the effectiveness of Australia's authority in the AAT, and the present territorial status of the AAT under the Treaty. It does this through a conceptual analysis of both the union and the divorce of the two central elements of territorial sovereignty: imperium and dominium. Part I provides an overview of the theories and principles of statehood, territorial sovereignty and title to territorial sovereignty as applied to remote and unpopulated dependencies. Part II addresses the dominant argument within the literature by examining the notion of effectiveness and extent of Australia's title to territorial sovereignty over the AAT. It constructs this analysis through the lens of the union of imperium and dominium over the AAT, and by utilising contemporary hierarchies of evidence that have emerged in international law in the post-war shift from territorial expansionism. Part III of this work addresses a gap in the literature by discussing the mechanisms of art IV of the Antarctic Treaty and how this disaggregates the imperium from the dominium. This aim is achieved by comparing the territorial aspects of the Treaty with other territorial regimes, such as Guantanamo Bay, the Mandated Territories, and United Nations Administrative regimes. The aim of this comparison is to provide a framework of analysis and discourse for the present, and perhaps perpetually enduring, status of the AAT, to step away from the vague descriptors such as 'frozen' and 'suspended'. This thesis shows that, while in a relative sense the title to territorial sovereignty in Antarctica is strong, that its legislative framework lacks specificity and clarity. It is also observed that the AAT's administrative framework is heavily concentrated in a highly specialised structure which is deeply ensconced in operations, in contrast to the separate governance structures typical of the other Antarctic dependencies. Further, it adds conceptual clarity to the interpretation of art IV of the Treaty and its operation on the territorial status of the AAT. It achieves this by using the analogy of divorce between dominium and imperium, and in doing so, removes some of the exceptionalism and mystery that art IV has attracted in both the academic and broader discourse.

description: As one of the lowest metallicity star forming galaxies, with a nucleus of several super star clusters, SBS0335-052E is the subject of substantial current study. We present new insights on this galaxy based on new and archival high spatial resolution NICMOS and ACS images. We provide new measurements and limits on the size of several of the SSCs. The images have sufficient resolution to divide the star formation into compact regions and newly discovered extended regions, indicating a bi-modal form of star formation. The star formation regions are dated via the equivalent width of the Pa alpha emission and we find that two of the extended regions of star formation are less than 10 million years old. Our previous finding that stellar winds confine the photo-ionizing flux to small regions around individual stars is consistent with the new observations. This may allow planet formation in what would traditionally be considered a harsh environment and has implications for the number of planets around globular cluster stars. In addition the images pinpoint the regions of H2 emission as located in, but not at the center of the two star forming super star clusters, S1 and S2.

Their analogues in terms of Bourgain spaces are then used as the main tool for the proof of bilinear estimates of the nonlinear terms of the equation and consequently of local well-posedness for the Cauchy problem.

Manufacture of vitamin B12 from sulfite spent liquor.
Creators: name: Ferguson, David Kimball
Publisher: name: University of British Columbia
Year: 2011

description: Up to 2 mg/l of vitamin B₁₂ were produced batch-wise using Propionibacterium freudenreichii on an ammonia based spent sulfite liquor medium in 250 ml Erlenmeyer flasks and a 7-litre benchtop fermentor. The up to 6 gm/l of bacteria utilized the hexoses from the SSL, thus reducing the BOD by 50-80% and producing, as by-products, 3 gm/1 of acetic acid and 7 gm/1 of propionic acid. Pre-treatment of the liquor required stripping of SO₂ to below 200 ppm and adjustment of the pH to between 6.5 and 7.5; precipitation of 1igno-su1fonate was not necessary. It was necessary to add excessive amounts (up to 75 gm/1 dry) of yeast extract or other supplementary nutrient to achieve these vitamin B₁₂ yields. Solutions to this nutrient problem are suggested. The Monod fermentation model whose parameters were estimated using non-linear least squares techniques with dry bacterial cell concentration as the dependent variable, approximate the batch data well. Other less complicated models were not as satisfactory. Estimating the model parameters using linear techniques was most unsatisfactory indeed. Optimum hold-up times for a single stage fermentor for Propionibacteria production, predicted from the Monod model whose parameters were estimated from batch data, were up to 125 hours. These hold-up time extrapolations are subject to large errors. Recommendations for further work on the vitamin B₁₂ process, the extension of the batch modeling work to continuous fermentation and further work on other more suitable microbiological products made from SSL are entertained.

description: With the proper choice of the dimensionality of the metric components, the action for all fields becomes dimensionless. Such quantities as the vacuum speed of light c, the Planck constant \hbar, the electric charge e, the particle mass m, the Newton constant G never enter equations written in the covariant form, i.e., via the metric g^{μν}. The speed of light c and the Planck constant are parameters of a particular two-parametric family of solutions of general relativity equations describing the flat isotropic Minkowski vacuum in effective theory emerging at low energy: g^{μν}=diag(-\hbar^2, (\hbar c)^2, (\hbar c)^2, (\hbar c)^2). They parametrize the equilibrium quantum vacuum state. The physical quantities which enter the covariant equations are dimensionless quantities and dimensionful quantities of dimension of rest energy M or its power. Dimensionless quantities include the running coupling `constants' α_i; topological and geometric quantum numbers (angular momentum quantum number j, weak charge, electric charge q, hypercharge, baryonic and leptonic charges, number of atoms N, etc). Dimensionful parameters include the rest energies of particles M_n (or/and mass matrices); the gravitational coupling K with dimension of M^2; cosmological constant with dimension M^4; etc. In effective theory, the interval s has the dimension of 1/M; it characterizes the dynamics of particles in the quantum vacuum rather than geometry of space-time. We discuss the effective action, and the measured physical quantities resulting from the action, including parameters which enter the Josepson effect, quantum Hall effect, etc.

The ecology and silviculture of Eucalyptus delegatensis : R.T. Baker on dolerite in Tasmania
Creators: name: Bowman, David
Publisher: name: University Of Tasmania
Year: 2023

description: Eucalyptus delegatensis is a widespread dominant of montane forests in southeastern Australia, where is occupies sites of widely varying moisture status and understorey type. The age and size class distributions of E. delegatensis on 23 sites of varying precipitation over its range on dolerite in Tasmania are strongly related to the floristic composition of the understorey vegetation and to moisture availability. No stands are even-aged, but all stands exhibit evidence of periodic rather than continuous recruitment; the periodicity of past recruitment events increasing with more mesic conditions. There is evidence for a change towards less frequent recruitment events in the higher rainfall stands since white settlement. An explanation for the variations in regeneration patterns is sought in the complex interactions between climate, fire frequency, fire intensity and understorey vegetation type. The trees in multi-aged forests at the dry end of the environmental range of E, delegatensis are extremely fire resistant while the survival of the even-aged saplings is dependent upon their height and bark thickness. Regeneration typically follows forest fire but experimental studies showed that germinates readily establish on cultivated seedbeds. Marked intraspecific competition occurs between the regeneration and the overwood trees. Experiments with germinates, seedlings, and advance growth indicate that soil drought prohibits rapid growth of regeneration beneath overwood while the higher levels of moisture available in forest gaps supports a dense stocking of vigorously growing saplings, Total removal of canopy cover results in a microclimate with greater maximum and lower minimum ground surface temperatures than in an environmentally similar unlogged stand. The poor health of regeneration on some high-altitude clear-felled forest sites is explained by the interactions of canopy cover, frost damage and topography. The various types of eucalypt silvicultural practices are subjectively classified as intensive, partial and selective systems. It is suggested that dry E. delegatensis forests are well suited to selective logging.

title: The Renascence of Classical Thought and Form in the Carolingian Period

description:
The political stability established under the rule of Charlemagne (768-814) was conducive to the flourishing of the simultaneous resurgence of art and learning. Inspired by the achievements of the Roman Empire, Charlemagne wished to give his subjects a feeling of spiritual unity, a sense of continuity with the past, and an enhanced intellectual life. The classical intellectual tradition is traced from ancient times to the Carolingian present to demonstrate that classicism was a continuum. The thesis examines the classical tradition in the intellectual life of the Carolingian period, its conscious rejuvenation in the figurative arts, and its manifestation in the imperial architecture of the ninth century. It demonstrates that the Carolingian resurgence of classicism was calculated rather than spontaneous. The widespread enthusiastic interest in classicism and its fresh interpretation were new, rather than classicism itself.
Foam separation of kraft mill effluents.

Publisher: name: University of British Columbia

description: A laboratory investigation into foam separation processes, as applied to kraft pulping and bleaching effluents is described. Two methods, foam fractionation and ion flotation were tested in the laboratory. The procedures developed concentrated primarily on the removal of effluent colour because this property lent itself most readily to the available analytical methods, and because effluent colour removal presents one of the greatest waste water treatment problems facing the industry today. The foam fractionation technique was not successful. Substantial colour removals were obtained, but it was subsequently shown that the mechanism of removal was really an ion flotation. Positive results were obtained with the use of the ion flotation process for removal of effluent colour. At optimum conditions, the recovery of flotable material and the corresponding removal of effluent colour were in excess of 95 per cent. Variation of surfactant dosage showed that below a critical level no colour was removed. As concentrations increased above this value the amount of colour removed increased rapidly, reaching a high removal level beyond which increases in surfactant concentration were of little value. The rate of flotation recovery was found to be significantly affected by the air sparge rate and the sparger pore size, both parameters which would determine the area available for adsorption. The pH of the flotation cell solution had a marked effect on the system. Optimum pH was clearly defined as 5.1. Removal of material other than just the chromophoric fraction was apparent. Biological oxygen demand data, while not extensive, demonstrate a significant reduction in the bio-degradable portion of the effluent. The possible future development of the process into a viable candidate for industrial application is discussed.

Exploring the relationship between alexithymia and empathy : the role of emotion recognition and metacognitive ability
Creators: name: Spicer, LC
Publisher: name: University Of Tasmania
Year: 2023

description: Alexithymic traits have been consistently found to be associated with deficits in social functioning. These social deficits in individuals with alexithymic traits have been suggested to be related to the reduced levels of empathy in those with alexithymic traits. Factors underlying this relationship, however, are presently not understood. Such an understanding may provide insight into addressing the empathy deficits seen in alexithymic individuals. This study aimed to support prior studies that indicate a relationship between cognitive and affective alexithymic traits and cognitive and affective domains of empathy, respectively. A preliminary investigation of the impact of emotion recognition ability (anger, fear, sadness) and metacognitive ability on the relationship between alexithymic traits and empathy was also of interest. One hundred and twenty participants aged between 18 and 55 years (68 females; `M` = 24.95, `SD` = 7.19) completed the Toronto Alexithymia Scale ‚Äö- 20, the Interpersonal Reactivity Index (IRI), the Emotion Recognition Task (ERT) and provided confidence ratings for each presented emotion of the ERT to assess metacognitive ability. The study identified negative relationships between cognitive alexithymic traits, and cognitive empathy across the emotions of anger, fear, and sadness. A moderated mediation effect for this relationship was also found for the emotion sadness. The findings suggest poor emotion recognition of sadness negatively impacts the relationship between cognitive alexithymic traits and cognitive empathy, but only for those with low levels of metacognitive ability. No significant relationships were found between affective alexithymic traits and affective empathy. These findings upon further testing in a clinical population may contribute to addressing empathy deficits seen in alexithymic individuals, in order to improve their social functioning.
Electron Capture $β$-Decay of $^7$Be Encapsulated in C$_{60}$: Origin of Increased Electron Density at the $^7$Be Nucleus

description: We offer a new theoretical interpretation for the effect of enhanced electron density at $^7$Be nucleus encapsulated in fullerene C$_{60}$. Our {\it{ab initio}} Hartree-Fock calculations show that electron density at the $^7$Be nucleus in $^7$Be@C$_{60}$ increase due to {\it{}attractive} effective potential well generated by the fullerene. The 2$s$ state in the isolated Be atom turns into 3$s$ state in the joint potential. This new state has higher energy, and slightly larger amplitude at the Be nucleus than the previous 2$s$ state. Moreover the 3$s$ wave function has additional {\it{}node} appeared at the distance $r \simeq 5a_B$ from the center. The node imitates repulsion between the Be electron and the fullerene wall, because the electron has zero probability to occupy this region. Such imitation of the repulsion by means of the node in attractive potential has direct physical analogy in the theory of $α$-$α$ and $N$-$N$ nuclear interactions.

description: (Abridged) We present a comprehensive analysis of the relationship between star formation rate surface density (SFR SD) and gas surface density (gas SD) at sub-kpc resolution in a sample of 18 nearby galaxies. We use high resolution HI data from THINGS, CO data from HERACLES and BIMA SONG, 24 micron data from the Spitzer Space Telescope, and UV data from GALEX. We target 7 spiral galaxies and 11 late-type/dwarf galaxies and investigate how the star formation law differs between the H2-dominated centers of spiral galaxies, their HI-dominated outskirts and the HI-rich late-type/dwarf galaxies. We find that a Schmidt-type power law with index N=1.0+-0.2 relates the SFR SD and the H2 SD across our sample of spiral galaxies, i.e., that H2 forms stars at a constant efficiency in spirals. The average molecular gas depletion time is ~2*10^9 yrs. We interpret the linear relation and constant depletion time as evidence that stars are forming in GMCs with approximately uniform properties and that the H2 SD may be more a measure of the filling fraction of giant molecular clouds than changing conditions in the molecular gas. The relationship between total gas SD and SFR SD varies dramatically among and within spiral galaxies. Most galaxies show little or no correlation between the HI SD and the SFR SD. As a result, the star formation efficiency (SFE = SFR SD / gas SD) varies strongly across our sample and within individual galaxies. We show that in spirals the SFE is a clear function of radius, while the dwarf galaxies in our sample display SFEs similar to those found in the outer optical disks of the spirals. Another general feature of our sample is a sharp saturation of the HI SD at ~9 M_sol/pc^2 in both the spiral and dwarf galaxies.

The effects of acute stress on behavioural and ERP measures of human attentional networks
Creators: name: Stone, CJ
Publisher: name: University Of Tasmania
Year: 2023

description: Neurobiological models suggest that acute stress facilitates bottom-up stimulus processing while impairing top-down executive control. To test this hypothesis, the present study investigated the effects of acute stress on behavioural (reaction time and accuracy) and electrophysiological (N1 and P3 ERP component amplitude) measures of the alerting, orienting, and executive attentional networks. Forty-three right-handed females aged 18-34 were recruited and performed the Attention Network Test (ANT) before and after the Maastricht Acute Stress Test (MAST) or a non-stressful MAST-placebo. Subjective Units of Distress Scale (SUDS) ratings and salivary cortisol concentrations were further collected as manipulation checks. While the manipulation checks revealed a successful stress induction, the hypothesised detrimental effect of acute stress on executive function was not found for reaction time (`p`=.524), accuracy (`p`=.657), or P3 amplitude (`p`=.408). Similarly, the hypothesised beneficial effect of stress on bottom-up stimulus processing was not found for measures of reaction time (`p`=.857) or N1 amplitude (`p`=.107). Supplementary analyses indicated that these findings were unrelated to the magnitude or duration of the stress response induced by the MAST, instead suggesting that the ANT itself may be insensitive to the effects of acute stress. Future research may utilise alternate versions of the ANT to address this possibility.
