description: To obtain a more complete understanding of the persisting gender earnings gap in Germany, this paper investigates both the cross-sectional and biographical dimension of gender inequalities. Using an Oaxaca Blinder decomposition, we show that the gender gap in annual earnings is largely driven by women’s lower work experience and intensive margin of labor supply. Based on a dynamic microsimulation model, we then estimate how gender di↵erences accumulate over work lives to account for the biographical dimension of the gender gap. We observe an average gender lifetime earnings gap of 51.5 percent for birth cohorts 1964-1972. We show that this unadjusted gender lifetime earnings gap increases strongly with the number of children, ranging from 17.8 percent for childless women to 68.0 percent for women with three or more children. However, using a counterfactual analysis we find that the adjusted gender lifetime earnings gap of 10 percent di↵ers only slightly by women’s family background.
Social behavior and feeding ability of two phenotypes of Gasterosteus aculeatus in relation to their spatial and trophic segregation in a temperate lake
Creators: name: Larson, Gary Lee
Publisher: name: University of British Columbia
Year: 2011

description: Significant differences in morphology, vertical distribution, aggressiveness, and feeding habits were found between limnetic and benthic forms of the threespine stickleback (Gasterosteus aculeatus) in a small coastal British Columbian lake. In deep laboratory aquaria, simulating lake pelagic and benthic regions, the benthic form was aggressive, solitary, and attracted to bottom cover, in which it remained. The limnetic form, in contrast, was gregarious, non-aggressive, attracted to surface cover, and seldom found near the bottom. In shallow aquaria, representing littoral lake regions, limnetic stickleback were aggressive and non-gregarious until cover was added, whereafter most individuals established residence in it and became significantly less aggressive. Benthic stickleback put into shallow aquaria huddled in small groups until cover was added, after which they spaced themselves out. These results were consistent with differences in the behavior of the two forms of stickleback in the field. The limnetic form fed heavily on zooplankton in the lake, while the benthic form mostly ate macro-benthos, Gammarus being its principal prey. Laboratory studies compared the feeding rates of both phenotypes; that of the limnetic form was highest on plankton, while that of the benthic form was highest on araphipods. The extensive dissimilarities demonstrated in social behavior and feeding ability of the two forms of stickleback indicate that their spatial and trophic segregation In Paxton Lake are due mainly to innate behavioral differences, rather than interaction.

description: In this paper, a novel cascade reaction of caesium carbonate-promoted Michael addition and lactonization for the one-pot synthesis of 3-alkyl-3-N-substituted aminobenzofuran-2(3H)-one derivatives has been established based on the screening of the alkaline catalysts and optimization of reaction conditions, in which the N-substituted (ortho-hydroxy) aryl glycine esters were used as the Michael donors to react with different α, β-unsaturated carbonyl compounds. Besides racemic enantiomers, the obtained epimers were successfully separated by conventional chromatography in the case of using the asymmetric raw material. In addition, the possible reaction mechanisms were suggested and the absolute configuration of the epimer was analysed. All the chemical structures of unreported benzofuran- 2(3H)-one derivatives were characterized by IR, 1H NMR, 13C NMR spectra and HRMS spectra.

description: We performed scanning tunneling spectroscopic experiments on hole-doped NdBa$_2$Cu$_3$O$_{7-δ}$. The d$I$/d$V$ curves obtained at 4.2 K are asymmetric with clear peak-dip and hump structures. Energy derivatives of these curves show peaks at energies beyond the dip features. Highly precise full potential bandstructure calculations confirm a featureless electronic density of states in that energy region. Our results indicate that tunneling electrons couple to a collective mode in the CuO$_2$ plane.

description: Heptamaloxyloglucan and Sorbitol, together commercialized as PEL101GV, was applied on Frontenac hybrid grapevines at 60 mg/ha and 100 g/ha respectively, 43 hours prior to a spring frost event in the Montérégie region (Quebec, Canada). In the test plot, the minimum temperature varied between -3.1 oC to -3.7 oC, as measured at the 70 cm shoot's height. The agents were compared to no-treatment in a complete randomized test block with 13 repetitions. The average shoot survival rate was 15.9% and 14.5% for the agent and the no-treatment respectively, but data analysis shows no statistical significance with p = 0.577. Data suggests that shoot survival rate is correlated to the physical position in the field. In the conditions tested, Heptamaloxyloglucan and Sorbitol were not effective at protecting against spring frost.

description: We prove a theorem about magnification relations for all generic general caustic singularities up to codimension five: folds, cusps, swallowtail, elliptic umbilic, hyperbolic umbilic, butterfly, parabolic umbilic, wigwam, symbolic umbilic, 2nd elliptic umbilic, and 2nd hyperbolic umbilic. Specifically, we prove that for a generic family of general mappings between planes exhibiting any of these singularities, and for a point in the target lying anywhere in the region giving rise to the maximum number of real pre-images (lensed images), the total signed magnification of the pre-images will always sum to zero. The proof is algebraic in nature and makes repeated use of the Euler trace formula. We also prove a general algebraic result about polynomials, which we show yields an interesting corollary about Newton sums that in turn readily implies the Euler trace formula. The wide field imaging surveys slated to be conducted by the Large Synoptic Survey Telescope are expected to find observational evidence for many of these higher-order caustic singularities. Finally, since the results of the paper are for generic general mappings, not just generic lensing maps, the findings are expected to be applicable not only to gravitational lensing, but to any system in which these singularities appear.

description: A large hadron machine like the LHC with its high track multiplicities always asks for powerful tools that drastically reduce the large background while selecting signal events efficiently. Actually such tools are widely needed and used in all parts of particle physics. Regarding the huge amount of data that will be produced at the LHC, the process of training as well as the process of applying these tools to data, must be time efficient. Such tools can be multivariate analysis -- also called data mining -- tools. In this contribution we present the results for the application of the multivariate analysis, rule growing algorithm RIPPER on a problem of particle selection. It turns out that the meta-methods bagging and cost-sensitivity are essential for the quality of the outcome. The results are compared to other multivariate analysis techniques.

description: The current trends of land use dynamics have revealed a significant transformation of settlement spaces. In the Wa Municipality of Ghana, the changes in land use and land cover are inspired by a plethora of driving forces. In this study, we assessed the geo-physical drivers of settlement expansion under land use dynamics in the Wa Municipality of Ghana. The study employed geospatial and remote sensing tools to map and analyse the spatio-temporal dynamics of the landscape, using Landsat satellite imageries: thematic mapper (TM), enhanced thematic mapper (ETM) and operational land imager (OLI) from 1990 to 2020. The study employed a binomial logistic regression model to statistically assess the geo-physical drivers of settlement expansion. Random forest (RF)–supervised classification based on spatio-temporal analyses generated relatively higher classification accuracies, with overall accuracy ranging from 89.33% to 93.3%. Urban expansion for the last three decades was prominent, as the period from 1990 to 2001 gained 11.44 km2 landmass of settlement, while there was 11.30 km2 gained from 2001 to 2010, and 29.44 km2 gained from 2010 to 2020. Out of the independent variables assessed, the distance to existing settlements, distance to river, and distance to primary, tertiary and unclassified roads were responsible for urban expansion.

Measurement of beauty photoproduction using decays into muons in dijet events at HERA
Creators: name: ZEUS Collaboration
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Beauty photoproduction in dijet events has been measured at HERA with the ZEUS detector using an integrated luminosity of 126 pb-1. Beauty was identified in events with a muon in the final state by using the transverse momentum of the muon relative to the closest jet. Lifetime information from the silicon vertex detector was also used; the impact parameter of the muon with respect to the primary vertex was exploited to discriminate between signal and background. Cross sections for beauty production as a function of the muon and the jet variables as well as dijet correlations are compared to QCD predictions and to previous measurements. The data are well described by predictions from next-to-leading-order QCD.

Slowly replicating lytic viruses: pseudolysogenic persistence and within-host competition

Year: 2008
Subjects: subject: Populations and Evolution (q-bio.PE)

description: We study the population dynamics of lytic viruses which replicate slowly in dividing host cells within an organism or cell culture, and find a range of viral replication rates that allows viruses to persist, avoiding extinction of host cells or dilution of viruses at too rapid or too slow viral replication. For the within-host competition between multiple viral strains, a strain with a "stable" replication rate could outcompete another strain with a higher or lower replication rate, therefore natural selection of viruses stabilizes the viral persistence. However, when strains with higher and lower than the "stable" value replication rates are both present, competition between strains does not result in dominance of one strain, but in their coexistence.

The metacognitive monitoring and study decisions of incremental theorists
Creators: name: Brumby, LE
Publisher: name: University Of Tasmania
Year: 2023

description: The present study investigated incremental theorists' metacognitive monitoring and study behaviours during a word-pair learning task. Sixty-five participants (38 female; aged 18-64 years, M = 33.92, SD = 14.40) studied English-Spanish word-pairs of differing difficulty (easy, moderate and difficult) and made judgments of learning (JOLs). Participants selected half of the word-pairs for restudy, before completing an initial cued-recall test to demonstrate the accuracy of their JOLs and study decisions. They then completed a restudy phase, incorporating a within-in subjects honour/dishonour manipulation, to assess the optimality of their study decisions. A final cued-recall test was administered, followed by Dweck's (1999) Theories of Intelligence Scale. Endorsing more incremental views of intelligence was marginally associated with poorer calibration for difficult word-pairs, (r = .235, p = .062), and was negatively associated with metacognitive accuracy for easy word-pairs during the study choice phase (r = -.260, p = .036). No further impairments were evident for the other difficulty-levels of these statistics, nor on over-confidence, under-confidence or resolution. Participants' study choices reflected a Discrepancy Reduction approach, and in general, did not appear to be optimal. Future research is required to further clarify these findings in reference to a larger entity theorist comparison group.
The predictive utility of social cognitive measures in determining functional outcomes after acquired brain injury
Creators: name: Lodge, MR
Publisher: name: University Of Tasmania
Year: 2023

description: Previous studies indicate that social cognition is impaired after an acquired brain injury (ABI). Social cognition refers to the ability to interpret and understand emotions, social settings and interpersonal exchanges. The present study examined impairments in social cognitive ability, and the predictive utility of social cognition in determining functional outcomes after an ABI. Thirty participants with an ABI (m= 18, f= 12) were recruited, and 30 healthy controls matched for similar sex, age and premorbid IQ. A series of independent samples t-tests compared the ABI and control participants on social cognitive measures. The relationship between the ABI participant's social cognitive ability and their functional outcomes were examined using eight hierarchical regressions. t-test results indicated that the ABI group performed significantly worse on the objective and informant measures of social cognition, while no significant differences on the self-reported social cognition measures were observed. Social cognition significantly predicted 43.5% of the variance in living skills on the participants rated outcome measure. The other regression models showed trends where social cognition predicted functional outcomes, however were non-significant. Clinical implications of the current study include facilitating assessments, by identifying individuals and their families who would benefit from more assistance and education.
Linear systems identification and optimization with application to adaptive control
Creators: name: Hanafy, Adel Abdel Raouf
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with the problem of identifying and controlling linear continuous systems. Algorithms which are feasible for real-time digital computations are developed for the design of both the controller and the identifier. The generalized equation error is shown to be applicable to a mean-square method of rapid digital estimation of linear system parameters. Due to the imposed structure of the estimator the manipulation of high order matrices is avoided. Examples illustrate the effectiveness of the estimator for a variety of cases dealing with quantization noise as well as measurements noise. In some cases, this digital identifier requires the computation of the generalized inverse of a matrix. A simple algorithm for computing the generalized inverse of a matrix is developed. This algorithm eliminates the need for Gram-Schmidt orthogonalization and its associated (in the interest of accuracy) reorthogonalization as new vectors are introduced. A two-stage estimator is developed for estimating time-invariant and time-varying parameters in linear systems. During the second stage, the time-varying parameters are considered as unknown control inputs to a linear subsystem of known dynamics. For the first stage, the digital identifier is shown to be effective in identifying the time-invariant parameters. Numerous examples illustrate the effectiveness of the method. To design a feedback controller a method of successive approximations for solving the two point boundary value problem for optimum constant gain matrices is developed. The method is shown to be comptationally equivalent to a deflected gradient method. Convergence can always be achieved by choice of a scalar step-size parameter. An online approximate method is developed which appears suitable for systems whose parameters must be identified. The two point boundary value problem is replaced by an algebraic problem, the solution of which gives a sub-optimal constant gains. The problem of trajectory sensitivity reduction by augmented state feedback is shown to be well-posed if constrained structure of the gain matrices is taken. The simple structure of constant gain matrices is considered. Based on the developed identifier and controller, one possible strategy for optimal adaptive control which is particularly attractive from an engineering point of view is studied. The strategy is to identify system parameters at the end of an observation interval and then to use the parameters to derive an "optimal" control for a subsequent control interval. Two examples are considered in order to illustrate the effectiveness of this strategy.
Attentional biases in spider fear: hypervigilance and disengagement difficulty
Creators: name: Nikitenko, T
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this study was to examine attentional biases of hypervigilance and disengagement difficulty in spider fear. Twenty-eight females between the ages of 18-36 years were grouped into high (n=14) and low (n=14) fear groups and completed a modified spatial cueing task comprising photographic cues of spiders (feared stimulus), beetles (neutral stimulus) and butterflies (positive valence stimulus). Cues were either valid (appeared on the same side as the target), or invalid (appearing on the opposite side). It was hypothesised that high fear participants would show faster reaction time and greater P1 amplitude following valid spider cues as an indicator of hypervigilance, and slower reaction times following invalid spider cues indexing disengagement difficulty. Instead, high fear participants showed greater reaction time to all targets, with this increase greater following spider cues. These findings were interpreted as interference following feared stimuli. P1 amplitude was higher overall in the high fear group, but both groups showed greater amplitude following spider cues relative to beetle and butterfly cues. Enhanced P1 amplitude in the high fear group was interpreted as increased attentional processing following feared images. This research provides preliminary support for Attentional Control Theory (ACT; Eyesenck et al., 2007) and suggests emphasis on attentional mechanisms in the treatment of spider fear.

description: The problem of \emph{statistical recognition} is considered, as it arises in immunobiology, namely, the discrimination of foreign antigens against a background of the body's own molecules. The precise mechanism of this foreign-self-distinction, though one of the major tasks of the immune system, continues to be a fundamental puzzle. Recent progress has been made by van den Berg, Rand, and Burroughs (2001), who modelled the \emph{probabilistic} nature of the interaction between the relevant cell types, namely, T-cells and antigen-presenting cells (APCs). Here, the stochasticity is due to the random sample of antigens present on the surface of every APC, and to the random receptor type that characterises individual T-cells. It has been shown previously that this model, though highly idealised, is capable of reproducing important aspects of the recognition phenomenon, and of explaining them on the basis of stochastic rare events. These results were obtained with the help of a refined large deviation theorem and were thus asymptotic in nature. Simulations have, so far, been restricted to the straightforward simple sampling approach, which does not allow for sample sizes large enough to address more detailed questions. Building on the available large deviation results, we develop an importance sampling technique that allows for a convenient exploration of the relevant tail events by means of simulation. With its help, we investigate the mechanism of statistical recognition in some depth. In particular, we illustrate how a foreign antigen can stand out against the self background if it is present in sufficiently many copies, although no \emph{a priori} difference between self and nonself is built into the model.

description: The presence of penetrated oils in the stratum corneum (SC), oil-induced occlusion of the SC and formation of occluding homogeneous film on the skin surface are discussed in relation to their influence on results of water profile calculations using conventional and newly proposed extended methods. It is shown that the conventional method does not determine the water profiles in treated skin correctly due to the superposition of Raman bands of SC's proteins and penetrated and remnant oils.

description: We present Doppler imaging and a Balmer line analysis of the weak-line T Tauri star TWA 17. Spectra were taken in 2006 with the UCL Echelle Spectrograph on the Anglo-Australian Telescope. Using least-squares deconvolution to improve the effective signal-to-noise ratio we produced a Doppler map of the surface spot distribution. This shows similar features to maps of other rapidly rotating T Tauri stars, i.e. a polar spot with more spots extending out of it down to the equator. In addition to the photospheric variability, the chromospheric variability was studied using the Balmer emission. The mean H-alpha profile has a narrow component consistent with rotational broadening and a broad component extending out to +/-220 km/s. The variability in H-alpha suggests that the chromosphere has at least one slingshot prominence 3 stellar radii above the surface.

description: The mass accretion rate of transonic spherical accretion flow onto compact objects such as black holes is known as the Bondi accretion rate(Mdot_B), which is determined only by the density and the temperature of gas at the outer boundary. But most work on disc accretion has taken the mass flux to be a given with the relation between that parameter and external conditions left uncertain. Within the framework of a slim alpha disk, we have constructed global solutions of the rotating, viscous hot accretion flow and determined its mass accretion rate as a function of density, temperature, and angular momentum of gas at the outer boundary. We find that the low angular momentum flow resembles the spherical Bondi flow and its mass accretion rate approaches the Bondi accretion rate for the same density and temperature at the outer boundary. The high angular momentum flow on the other hand is the conventional hot accretion disk with advection, but its mass accretion rate can be significantly smaller than the Bondi accretion rate with the same boundary conditions. We also find that when the temperature at the outer boundary is equal to the virial temperature, solutions exist only for 0.05 ~< mdot ~< 1 when alpha=0.01 where mdot==Mdot/Mdot_B. We also find that the dimensionless mass accretion rate is roughly independent of the radius of the outer boundary but inversely proportional to the angular momentum at the outer boundary and proportional to the viscosity parameter, mdot ~= 9.0 alpha/lambda when 0.1 ~< mdot ~< 1, where the dimensionless angular momentum measure lambda == l_out/l_B is the specific angular momentum of gas at the outer boundary l_out in units of l_B == GM/c_{s,out}, and $c_{s,out}$ the isothermal sound speed at the outer boundary.

description: We study the power of nonadaptive quantum query algorithms, which are algorithms whose queries to the input do not depend on the result of previous queries. First, we show that any bounded-error nonadaptive quantum query algorithm that computes some total boolean function depending on n variables must make Omega(n) queries to the input in total. Second, we show that, if there exists a quantum algorithm that uses k nonadaptive oracle queries to learn which one of a set of m boolean functions it has been given, there exists a nonadaptive classical algorithm using O(k log m) queries to solve the same problem. Thus, in the nonadaptive setting, quantum algorithms can achieve at most a very limited speed-up over classical query algorithms.

description: A system of two coupled ensembles of phase oscillators can follow different routes to inter-ensemble synchronization. Following a short report of our preliminary results [Phys. Rev. E. {\bf 78}, 025201(R) (2008)], we present a more detailed study of the effects of coupling, noise and phase asymmetries in coupled phase oscillator ensembles. We identify five distinct synchronization regions, and new routes to synchronization that are characteristic of the coupling asymmetry. We show that noise asymmetry induces effects similar to that of coupling asymmetry when the latter is absent. We also find that phase asymmetry controls the probability of occurrence of particular routes to synchronization. Our results suggest that asymmetry plays a crucial role in controlling synchronization within and between oscillator ensembles, and hence that its consideration is vital for modeling real life problems.

description: This PhD program proposes innovative ideas within a comprehensive and yet umbrella definition as indicated through the title. Above all, this thesis provides a comprehensive compendium of experimental results on a variety of aspects of buckling of thin walled steel elements and an invaluable resource of experimental data for the later studies of such structural elements. This thesis experimentally investigates the structural stability of thin-walled steel members with different geometrical and material specifications. For tubular circular members made exclusively from steel, large imperfections in the form of dents were examined under axial loading, bending and external pressure. As another form of geometrical irregularity, different shapes and geometries of cutouts were considered in order to investigate the effect of these imperfections on the structural behaviour of the steel members. Circular shell elements with normal fabrication-related imperfections were investigated under external pressure. Reinforcement of the shell members with additional elements (stiffeners/thickeners) and without additional material (corrugation) was also undertaken. Large imperfections such as dents and cutouts with different sizes were then examined for circular tubes under cyclic loading. Rehabilitation of members with cutouts (using Carbon Fibre Reinforced Polymer, CFRP), fully recovered the reduced capacity resulted from the existence of the cutouts; yet, employed reinforcements manifested capacities well above the intact models. Sectional irregularity was also of a great interest in this PhD thesis, which was adopted for composite members. Composite elements such as CFRP and timber were combined with thin-walled steel members to produce light-weight elements with great structural efficiency. Timber cores with different cross sections were utilised for timber filled CHS steel tubular sections. CFRP reinforced the timber-filled CHS members from outside the steel so that both inward and outward buckling was restricted. The same scenario was used for the CHS members with timber and concrete cores, in which the timber blocks were employed to act as compressive members, alongside their key role to form (cast) the concrete inside the tubes. Bending members including timber, reinforced by U-shape steel members were designed in order to make a light-weight flexural element. The effect of such strengthening on the capacity as well as the ductility of the beams in question was evaluated.

description: Astrophysical parameters (\textit{age, reddening, distance, core and cluster radii}) of 14 open clusters (OCs) projected close to the Galactic plane are derived with 2MASS photometry. The OCs are Be 63, Be 84, Cz 6, Cz 7, Cz 12, Ru 141, Ru 144, Ru 172, FSR 101, FSR 1430, FSR 1471, FSR 162, FSR 178 and FSR 198. The OCs Be 63, Be 84, Ru 141, Ru 144, and Ru 172 are studied in more detail than in previous works, while the others have astrophysical parameters derived for the first time. The open clusters of the sample are located at $d_\odot=1.6-7.1$ kpc from the Sun and at Galactocentric distances $5.5-11.8$ kpc, with age in the range 10 Myr to 1.5 Gyr and reddening $E(B-V)$ in the range $0.19-2.56$ mag. The core and cluster radii are in the range $0.27-1.88$ pc and $2.2-11.27$ pc, respectively. Cz 6 and FSR 198 are the youngest OCs of this sample, with a population of pre-main sequence (PMS) stars, while FSR 178 is the oldest cluster.

More on the Finiteness of Anomalous Magnetic Moment in the Gauge-Higgs Unification

description: We discuss the anomalous magnetic moment of fermion in a realistic SU(3) model of gauge-Higgs unification compactified on an orbifold S^1/Z_2 including Z_2-odd bulk mass for fermions. An operator analysis implies that the anomalous magnetic moment should be finite and predictable, even though higher dimensional gauge theories are non-renormalizable. Our main purpose is to clarify the cancellation mechanism of the UV divergences appearing in various types of Feynman diagrams. The cancellation of divergence turns out to take place between the contributions of the "partners" in the Higgs-like mechanism present in the non-zero Kaluza-Klein modes to form massive gauge bosons. It is also argued that the cancellation may be attributed to the quantum mechanical SUSY hidden in the scenario of gauge-Higgs unification.

description: The globalised cascaded scattering matrix technique is a well proven, practical method that can be used to simulate large accelerating RF structures in which realistic fabrication errors to be incorporated in an efficient manner without the necessity to re-mesh the entire geometry. The globalised scattering matrix (GMS) technique allows one to obtain the scattering matrix for a structure. The method allows rapid e.m. field calculations to be obtained. Results are presented on monopole mode fields and dispersion relations calculated from direct and analytical methods. Analytical approximate results are also presented for the equivalent shunt susceptance of an iris loaded structure.

description: A theorem related to the Newman-Penrose constants is proven. The theorem states that all the Newman-Penrose constants of asymptotically flat, stationary, asymptotically algebraically special electrovacuum spacetimes are zero. Straightforward application of this theorem shows that all the Newman-Penrose constants of the Kerr-Newman spacetime must vanish.

Infrared behavior and spectral function of a Bose superfluid at zero temperature
Creators: name: Dupuis, N.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: In a Bose superfluid, the coupling between transverse (phase) and longitudinal fluctuations leads to a divergence of the longitudinal correlation function, which is responsible for the occurrence of infrared divergences in the perturbation theory and the breakdown of the Bogoliubov approximation. We report a non-perturbative renormalization-group (NPRG) calculation of the one-particle Green function of an interacting boson system at zero temperature. We find two regimes separated by a characteristic momentum scale $k_G$ ("Ginzburg" scale). While the Bogoliubov approximation is valid at large momenta and energies, $|\p|,|\w|/c\gg k_G$ (with $c$ the velocity of the Bogoliubov sound mode), in the infrared (hydrodynamic) regime $|\p|,|\w|/c\ll k_G$ the normal and anomalous self-energies exhibit singularities reflecting the divergence of the longitudinal correlation function. In particular, we find that the anomalous self-energy agrees with the Bogoliubov result $\Sigan(\p,\w)\simeq\const$ at high-energies and behaves as $\Sigan(\p,\w)\sim (c^2\p^2-\w^2)^{(d-3)/2}$ in the infrared regime (with $d$ the space dimension), in agreement with the Nepomnyashchii identity $\Sigan(0,0)=0$ and the predictions of Popov's hydrodynamic theory. We argue that the hydrodynamic limit of the one-particle Green function is fully determined by the knowledge of the exponent $3-d$ characterizing the divergence of the longitudinal susceptibility and the Ward identities associated to gauge and Galilean invariances. The infrared singularity of $\Sigan(\p,\w)$ leads to a continuum of excitations (coexisting with the sound mode) which shows up in the one-particle spectral function.

Parent, teacher and pre-adolescent lived experiences of wellbeing and spirituality: A hermeneutic phenomenological study
Creators: name: Manton, Claire
Publisher: name: Monash University
Year: 2021
Subjects: Education

description: This thesis questions the vague positioning of spirituality in the context of education, particularly as it is situated in relation to wellbeing. Interviews were conducted with teachers, parents and pre-adolescent students from two Victorian schools and the interviews were analysed using a hermeneutic phenomenological method. Findings from this research posit that wellbeing and spirituality are essentially relational phenomena. This study draws on the ontological philosophy of Heidegger and Gadamer to offer an ontological interpretation of wellbeing and spirituality. In doing so, this study offers responsive and emancipatory conditions to support pre-adolescent students, in particular, in relation to the phenomena.
