Subjects: Other education not elsewhere classified

description: Emotional labour has been a burgeoning research area among scholars because of its significance for employees and organisations. However, there is scarce research on emotional labour among high professional service jobs as compared to customer service jobs. Moreover, little research has been done on emotional labour among academics and how they cope with the emotional labour requirements of their teaching role. To address this gap, this study focuses on examining the emotional labour requirements of academics and specifically on whether and how communities of coping allow academics to manage the emotional labour requirements of their teaching role. This thesis employs a qualitative case study methodology, utilising semi-structured interviews to collect data from Australian business schools’ academics. Findings show various emotional labour requirements for academics such as being enthusiastic, calm and mindful. Adhering to such occupational emotional labour requirements results in emotional exhaustion among academics. The study demonstrates that communities of coping play an imperative role in dealing with emotional labour requirements of academics. This research concludes that despite the significance of communities of coping in academia, its scope is narrowed down due to the encroachment of managerialism, intensified research expectations and increased workload. This study contributes to the emotional labour scholarship and extends existing research on the academic profession.

description: Inspired by river networks and other structures formed by Laplacian growth, we use the Loewner equation to investigate the growth of a network of thin fingers in a diffusion field. We first review previous contributions to illustrate how this formalism reduces the network's expansion to three rules, which respectively govern the velocity, the direction, and the nucleation of its growing branches. This framework allows us to establish the mathematical equivalence between three formulations of the direction rule, namely geodesic growth, growth that maintains local symmetry and growth that maximizes flux into tips for a given amount of growth. Surprisingly, we find that this growth rule may result in a network different from the static configuration that optimizes flux into tips.

description: Education today stands at a cross roads. There is a growing pressure on schools to reform towards a vision of 21st Century Education, with key education stakeholders demanding a radical re-envisioning of schooling to meet the needs of dynamic and ever-changing world. Yet Australian schools also exist within a neoliberal culture of external surveillance and accountability which narrow the curriculum towards a focus on performance in standardised testing in an unprecedented era of global school competition. With dozens of competing models and variations of 21st Century Education emerging over the past 20 years, significant ambiguity exists around the concept. This poses a difficulty for schools as they seek to interpret and apply the concept of 21st Century Education into their unique contexts. This is compounded further by the lack of significant research in the area, given that it is emergent best practice. Principals are therefore in a place of key tension. With competing demands for school improvement and reform, principals must determine if and how they approach the concept of 21st Century Education. This study therefore explores, through interviews and observations, how three principals in NSW, Australia are interpreting the concept and then leading school reform within their local contexts. Analysis extends to include the leadership styles and change management processes that are enacted. Similarities and differences between the case studies are identified and the implications discussed.

description: Particulate matter was sampled in Northern France during two summer and winter periods at both an urban background site (Douai, DO) and an industrialized coastal site (Grande-Synthe, GS). Ambient levels of particulate carbonaceous species and Polycyclic Aromatic Hydrocarbons (PAH) were measured by real-time measurements and via collection and analysis of offline filters (F). The comparison between online organic matter (OM) measured by an Aerosol Mass Spectrometer (AMS) and organic carbon (OC) determined by an offline thermal-optical method showed good linear trends in wintertime GS (r2 = 0.82 while only 0.50 in summer), and DO (r2 = 0.86 in summer and 0.92 in winter). However, significant differences were observed between analytical methods and sites with OCAMS/OCF ratios decreasing from 0.80 in DO during winter to ≈0.20 for GS in summer, suggesting that a large part of OM could be in the PM1–PM2.5 fraction. The simultaneous measurements of Black Carbon (BC) and Elemental Carbon (EC) concentrations in PM2.5 were also well correlated at both sites with r2 = 0.61–0.97 and slopes between 0.6 and 0.8. PAHs were analyzed in PM2.5 and also measured online by AMS in PM1. Their wintertime concentrations were highly correlated in DO (r2 = 0.98) and to a lesser degree in GS (r2 = 0.67). r2 values determined for comparison between online and offline parameters (OC and PAHs) in GS were lower than in DO, probably due to a more complex aerosol composition and a higher variability of the physical and chemical properties resulting from the coastal situation and diversity of emission sources in the vicinity of GS.

description: In this paper we deal with two quantum relative entropy preserver problems on the cones of positive (either positive definite or positive semidefinite) operators. The first one is related to a quantum Rényi relative entropy like quantity which plays an important role in classical-quantum channel decoding. The second one is connected to the so-called maximal $f$-divergences introduced by D. Petz and M. B. Ruskai who considered this quantity as a generalization of the usual Belavkin-Staszewski relative entropy. We emphasize in advance that all the results are obtained for finite dimensional Hilbert spaces.

description: Aerosols directly affect Earth's climate by scattering and absorbing solar radiation. Although they are ubiquitous in Earth's atmosphere, direct, in situ, wavelength-resolved measurements of aerosol optical properties remain challenging. As a result, the so-called aerosol direct effects are one of the largest uncertainties in predictions of Earth's future climate, and new instrumentation is needed to provide measurements of the absorption of sunlight by atmospheric particles. We have developed a portable, four-wavelength, single-cell photoacoustic spectrometer for simultaneous measurement of aerosol absorption at 406, 532, 662, and 785 nm, with an additional extinction measurement at 662 nm via a built-in cavity ringdown spectrometer. The instrument, dubbed MultiPAS-IV, is compact, robust, has low power requirements, and utilizes a multipass optical arrangement to achieve typical detection limits of 0.6–0.7 Mm−1 for absorption (2σ, 2-min average). Tests with nigrosin aerosols show agreement with Mie theory calculations to within 2%, and comparison with a 7-wavelength aethalometer shows good correlation for ambient (Athens, GA, USA) aerosols. We demonstrate the utility of the broad spectral coverage and sensitivity of the MultiPAS-IV for calculating the absorption Ångström exponent of black carbon (AAEBC, median value of 0.70) in ambient aerosols and use this value to derive the brown carbon contributions to absorption at 406 nm (43%) and 532 nm (13%) and its wavelength dependence (AAEBrC = 6.3).

description: This paper analyses an SIRS-type model for infectious diseases with account for behavioural changes associated with the simultaneous spread of awareness in the population. Two types of awareness are included into the model: private awareness associated with direct contacts between unaware and aware populations, and public information campaign. Stability analysis of different steady states in the model provides information about potential spread of disease in a population, and well as about how the disease dynamics is affected by the two types of awareness. Numerical simulations are performed to illustrate the behaviour of the system in different dynamical regimes.

description: We present differential $UBV$ photoelectric photometry obtained by Williamon of the short-period A-type W~UMa binary MW~Pav. With the Wilson-Devinney analysis program we obtained a simultaneous solution of these observations with the $UBV$ photometry of Lapasset (1977,1980), the $V$ measurements by the $ASAS$ program, and the double-lined radial velocity measurements of Rucinski & Duerbeck (2006). Our solution indicates that MW~Pav is in an overcontact state, where both components exceed their critical Roche lobes. We derive masses of $M_1 = 1.514 \pm 0.063 \, M_\sun$ and $M_2 = 0.327 \pm 0.014 \, M_\sun$, and equal-volume radii of $R_1 = 2.412 \pm 0.034 \, R_\sun$ and $R_2 = 1.277 \pm 0.019 \, R_\sun$ for the primary and secondary, respectively. The system is assumed to have a circular orbit and is seen at an inclination of $86.39\arcdeg \pm 0.63\arcdeg$. The effective temperature of the primary was held fixed at $6900$~K, whereas the secondary's temperature was found to be $6969 \pm 10$~K. The asymmetry of the light curves requires a large, single star spot on the smaller, less massive secondary component. A consistent base solution, with different spot characteristics for the Williamon, Lapasset, and $ASAS$ data, was found. The modeled spot varied little during the 40-year range of photometric observations. The combined solution utilized a third light component and found that the period is changing at a rate of dP/dt~=~$(6.50 \pm 0.19) \times 10^{-10}$.

description: As part of the mm-Wave Interferometric Survey of Dark Object Masses (WISDOM) project, we present an estimate of the mass of the supermassive black hole (SMBH) in the nearby fast-rotating early-type galaxy NGC4697. This estimate is based on Atacama Large Millimeter/submillimeter Array (ALMA) cycle-3 observations of the 12CO(2-1) emission line with a linear resolution of 29 pc (0.53"). We find that NGC4697 hosts a small relaxed central molecular gas disc with a mass of 1.6x10^7 Msun, co-spatial with the obscuring dust disc visible in optical Hubble Space Telescope (HST) imaging. We also resolve thermal 1mm continuum emission from the dust in this disc. NGC4697 is found to have a very low molecular gas velocity dispersion, $σ_{gas}=1.65^{+0.68}_{-0.65}$ km/s. This seems to be partially because the giant molecular cloud mass function is not fully sampled, but other mechanisms such as chemical differentiation in a hard radiation field or morphological quenching also seem to be required. We detect a Keplerian increase of the rotation of the molecular gas in the very centre of NGC4697, and use forward modelling of the ALMA data cube in a Bayesian framework with the KINematic Molecular Simulation (KinMS) code to estimate a SMBH mass of ($1.3_{-0.17}^{+0.18})\times10^8$ Msun and an i-band mass-to-light ratio of $2.14_{-0.05}^{+0.04}$ Msun/Lsun (at the 99% confidence level). Our estimate of the SMBH mass is entirely consistent with previous measurements from stellar kinematics. This increases confidence in the growing number of SMBH mass estimates being obtained in the ALMA era.

description: Ionization of atoms and molecules in laser fields can lead to various interesting interference structures in the photoelectron spectrum. For the case of a super-intense extreme ultraviolet laser pulse, we identify a novel petal-like interference structure in the electron momentum distribution along the direction of the laser field propagation. We show that this structure is quite general and can be attributed to the Fresnel diffraction of the electronic wavepacket by the nucleus. Our results are demonstrated by numerically solving the time-dependent Schrodinger equation of the atomic hydrogen beyond the dipole approximation. By building an analytical model, we find that the electron displacement determines the aforementioned interference pattern. In addition, we establish the physical picture of laser-induced electron Fresnel diffraction which is reinforced by both quantum and semiclassical models.

description: This thesis examines the alleged assassination of Teti, and the subsequent succession of Weserkare followed by Pepy I. The apparent murder of his father and usurpation of the throne by Weserkare tempered the interaction between Pepy I and his officials. He altered the policy of government in the provinces, often dividing the high titles between a number of individuals. He attempted to create loyalty within the ranks of his officials by marrying into high ranking families, marrying his own relatives into others and educating the sons of provincial officials in the capital. where they also initially served in low ranking positions. Many of thee were also policies of his father Teti. Despite this, Pepy I appears to have trusted very few, with a number of provincial officials also serving from the capital. This mistrust was well placed as he was the subject of an unsuccessful plot himself, one involving his nephew and vizier Rawer. While there were a great number of intriguing problems in the early Sixth Dynasty, it does not appear that there was a process of decentralisation occurring which would contribute to the fall of the Old Kingdom.

description: The paper addresses the image fusion problem, where multiple images captured with different focus distances are to be combined into a higher quality all-in-focus image. Most current approaches for image fusion strongly rely on the unrealistic noise-free assumption used during the image acquisition, and then yield limited robustness in fusion processing. In our approach, we formulate the multi-focus image fusion problem in terms of an analysis sparse model, and simultaneously perform the restoration and fusion of multi-focus images. Based on this model, we propose an analysis operator learning, and define a novel fusion function to generate an all-in-focus image. Experimental evaluations confirm the effectiveness of the proposed fusion approach both visually and quantitatively, and show that our approach outperforms state-of-the-art fusion methods.

description: Chord recognition systems depend on robust feature extraction pipelines. While these pipelines are traditionally hand-crafted, recent advances in end-to-end machine learning have begun to inspire researchers to explore data-driven methods for such tasks. In this paper, we present a chord recognition system that uses a fully convolutional deep auditory model for feature extraction. The extracted features are processed by a Conditional Random Field that decodes the final chord sequence. Both processing stages are trained automatically and do not require expert knowledge for optimising parameters. We show that the learned auditory system extracts musically interpretable features, and that the proposed chord recognition system achieves results on par or better than state-of-the-art algorithms.

Evaluating Kiama abstract state machines for a Java implementation
Creators: name: Suvanpong, Pongsak
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis represents nine months of research in the area of embedded domain-specific programming languages. Kiama is a pure embedded lightweight language processing library in Scala. It provides classes for language processing paradigms such as attribute grammars, strategic term rewriting and abstract state machines (ASM) which can be used for analyzing, translating and executing languages. In this thesis, we evaluate the ASM component of Kiama by implementing several complex machines for executing the dynamic semantics of the Java language and the Java Virtual Machine byte code into which it is translated. We use the book “Java and the Java Virtual Machine: Definition, Verification and Validation” by R. Stärk, J. Schmid and E. Börger, as our reference. The book describes the Java language version 1.2 using the ASM method. We are able to implement the machines without any modifications to Kiama's ASM. The combination of Scala and Kiama allows us to closely replicate the book’s ASM notations in executable code. However, we find a few problems with the Kiama ASM library for which we show workarounds. In addition, we discover a few bugs in the book's machine definitions and provide fixes in our implementation.

description: Seyfert 1.8/1.9 are sources showing weak broad H-alpha components in their optical spectra. We aim at testing whether Seyfert 1.8/1.9 have similar properties at UV and X-ray wavelengths to Seyfert 2. We use the 15 Seyfert 1.8/1.9 in the Veron Cetty and Veron catalogue with public data available from the Chandra and/or XMM-Newton archives at different dates, with timescales between observations ranging from days to years. Our results are homogeneously compared with a previous work using the same methodology applied to a sample of Seyfert 2 (Hernandez-Garcia et al. 2015). X-ray variability is found in all 15 nuclei over the aforementioned ranges of timescales. The main variability pattern is related to intrinsic changes in the sources, which are observed in ten nuclei. Changes in the column density are also frequent, as they are observed in six nuclei, and variations at soft energies, possibly related to scattered nuclear emission, are detected in six sources. X-ray intraday variations are detected in six out of the eight studied sources. Variations at UV frequencies are detected in seven out of nine sources. A comparison between the samples of Seyfert 1.8/1.9 and 2 shows that, even if the main variability pattern is due to intrinsic changes of the sources in the two families, these nuclei exhibit different variability properties in the UV and X-ray domains. In particular, variations in the broad X-ray band on short time-scales (days/weeks), and variations in the soft X-rays and UV on long time-scales (months/years) are detected in Seyfert 1.8/1.9 but not in Seyfert 2. Overall, we suggest that optically classified Seyfert 1.8/1.9 should be kept separated from Seyfert 2 galaxies in UV/X-ray studies of the obscured AGN population because their intrinsic properties might be different.

description: We use effective kinetic theory to study the pre-equilibrium dynamics in heavy-ion collisions. We describe the evolution of linearized energy perturbations on top of out-of-equilibrium background to the energy-momentum tensor at a time when hydrodynamics becomes applicable. We apply this description to IP-Glasma initial conditions and find an overall smooth transition to hydrodynamics. In a phenomenologically favorable range of $η/s$ values, early time dynamics can be accurately described in terms of a few functions of a scaled time variable $τT/(η/s)$. Our framework can be readily applied to other initial state models to provide the pre-equilibrium dynamics of the energy momentum tensor.

description: The escalating impacts of climate change on coastal regions stress the urgency for effective adaptation strategies, particularly for the case of high-risk countries such as Bangladesh. Nature-based solutions, grey and mixed coastal infrastructure offer promising solutions for addressing these challenges. Prior publications have utilized decision-making models such as the DPSIR framework to explore the link between coastal infrastructure and climate change. However, until now none of them have used it in combination with broader frameworks. Moreover, few works have analyzed the south central coast of Bangladesh by following an integrated approach. Hence, this working paper aims to bridge these gaps by employing an integrated SES-DAPSIR framework to evaluate the main benefits and challenges provided by different types of coastal infrastructure, with a particular emphasis on ecosystem services. Our methodology involves a two-step approach. Firstly, we consolidated a structured questionnaire and conducted surveys within three different locations to gather community’s perspectives on coastal infrastructure. Secondly, we developed an integrated SES-DAPSIR conceptual model, engaging scientific and policymaking stakeholders through an international workshop co-organized with FEEM, Università Ca’ Foscari and Murdoch University. The main results highlight the potential ecological impacts and costs associated with grey infrastructure, advocating for a balanced approach that combines green and grey solutions. Mixed solutions, integrating elements of both nature-based and grey infrastructure, show promise for optimizing adaptation efforts while minimizing ecological harm and cost. As part of this process, government leadership and international cooperation are deemed essential for driving public engagement and fostering societal resilience.

description: We investigate the potential existence of a superconducting phase in $5d$ Mott insulators with an eye to hole doped Sr$_2$IrO$_4$. Using a mean-field method, a mixed singlet-triplet superconductivity, $d + p$, is observed due to the antisymmetric exchange originating from a quasi-spin-orbit-coupling. Our calculation on ribbon geometry shows possible existence of the topologically protected edge states, because of nodal structure of the superconducting gap. These edge modes are spin polarized and emerge as zero-energy flat bands, supporting a symmetry protected Majorana states, verified by evaluation of winding number and $\mathbb{Z}_2$ topological invariant. At the end, a possible experimental approach for observation of these edge states and determination of the superconducting gap symmetry are discussed based on the quasi-particle interference (QPI) technique.

description: Working within the context of PT-symmetric quantum mechanics, we begin by describing a non-Hermitian extension of QED that is both Lorentz invariant and consistent with unitarity. We show that the non-Hermitian Dirac mass matrix of this theory exhibits an exceptional point, corresponding to an effectively massless theory whose conserved current is either right- or left-chiral dominated. With this inspiration, we are able to construct a non-Hermitian model of light Dirac neutrino masses from Hermitian and anti-Hermitian Yukawa couplings that are both of order unity. We finish by highlighting potential phenomenological implications of this model.

description: We performed a global study on the timing and spectral properties of type-B quasi-periodic oscillations (QPOs) in the outbursts of black hole X-ray binaries. The sample is built based on the observations of {\it Rossi X-ray Timing Explorer}, via searching in the literature in RXTE era for all the identified type-B QPOs. To enlarge the sample, we also investigated some type-B QPOs that are reported but not yet fully identified. Regarding to the time lag and hard/soft flux ratio, we found that the sources with type-B QPOs behave in two subgroups. In one subgroup, type-B QPO shows a hard time lag that firstly decreases and then reverse into a soft time lag along with softening of the energy spectrum. In the other subgroup, type-B QPOs distribute only in a small region with hard time lag and relatively soft hardness. These findings may be understood with a diversity of the homogeneity showing up for the hot inner flow of different sources. We confirm the universality of a positive relation between the type-B QPO frequency and the hard component luminosity in different sources. We explain the results by considering that the type-B QPO photons are produced in the inner accretion flow around the central black hole, under a local Eddington limit. Using this relationship, we derived an mass estimation of $9.3-27.1$ $\rm{M_{\odot}}$ for the black hole in H 1743-322.

Estimating the baryonic masses of face-on spiral galaxies from stellar kinematics

description: The kinematic dispersions of disc stars can be used to measure the dynamic contributions of baryons to the rotation curves of spiral galaxies and hence to trace the amount and distribution of the remaining dark matter. However, the simple single-component infinite disc model traditionally used to convert stellar dispersions to mass-densities is no longer adequate. The dark matter halo has a significant effect upon the stellar dispersions for any non-maximal disc. The correction for cuspy dark matter halos is particularly large, suggesting that such models are not consistent with the observed stellar dispersions. When a more realistic model for the vertical gravity of the disc is used, the derived stellar surface densities are generally larger (smaller) for disc radii smaller (larger) than 2.3 times the radial scale-length. When the vertical gravity correction is applied to the radially resolved stellar mass-to-light ratios derived by the DiskMass consortium, the true values are not constant but decrease with radius, as expected from photometric colour gradients, and the true mass scale-lengths are about 80% of the photometric scale-lengths. The effects of a thin gaseous disc are larger than expected, especially when an allowance is made for optically thick or CO-dark gas. The presence of a thick-disc stellar component has severe consequences, particularly if its radial scale-length is smaller than that of the thin disc, as it appears to be in the Milky Way.

description: The evolution of television and broadcasting technology from analogue to digital brings about changes in the global television industry. This technological transition is related to a political push which is highly concerned with national public interest in relation to socio-economic forces. Thailand's TV industry has also adopted and used digital television (DTV) technologies since the late 1990s in its TV production and broadcasting. The Thai government broadcasting regulators are expected to play a key role in launching and issuing national DTV policy. However, they seem to be involved in a conflict of interest which has negatively impacted Thailand's DTV transition. --This study selects Thailand's TV industry as a case study of a developing country in response to global technological transition. The thesis aims to explore major drives influencing Thai broadcasting in the shift from analogue to digital. It provides recommendations vis-à-vis the establishment of national DTV policy, and the current use of DTV technologies by Thai TV stations. The research project was conducted in Bangkok, Thailand, between October 2006 and October 2007, after the September coup in 2006. Two research methodologies employed in the study are (1) in-depth interviews with 26 experts (TV station administrators and mass communication scholars), and (2) observations of the nine TV stations. --Theoretical concepts in globalisation of communication echnologies and communication policy are reviewed. The research reveals two major pushes significantly forcing Thailand's TV industry into a newly administrative sphere. These are: (1) global push, and (2) domestic push; both are extensively addressed in this thesis.

description: In this study, the ion-imprinting method has been integrated to develop a novel composite material for the selective separation of Pb2+ ions. Also, Pb2+ ion binding ability of the organosmectite based inorganic-organic composite incorporation of bicyclic C18 organic compound into smectite layers was conducted to draw a projection its potential use as a solid phase exchanger which is quite selective toward Pb2+ ions. The ion-imprinted nanocomposites were characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), swelling tests, and elemental analyses. After that, maximum binding capacity, pH, and equilibrium binding time were also been optimized. In order to show the selectivity of the composite synthesized, non-imprinted composites were also synthesized in absence of Pb2+ ions during polymerization. In this step, Ni2+, Co2+, Al3+, Zn2+, and Cu2+ ions were used as competitors under batch adsorption conditions. The relative selectivity coefficients of imprinted composite were calculated as 28.5, 156.5, 69.3, 24.8 and 131.6 for Pb2+/Co2+, Pb2+/Cu2+, Pb2+/Al3+, Pb2+/Zn2+, Pb2+/Ni2+ binary solutions, respectively. Finally, reusability of the composites was evaluated to show its cost-efficiency by repeating adsorption-desorption experiments ten-times. The adsorption capacity of the imprinted composites did not change significantly whereas that of non-imprinted version reduced dramatically.

description: Premised upon the observation that MOOC and crowdsourcing phenomena share several important characteristics, including IT mediation, large-scale human participation, and varying levels of openness to participants, this work systematizes a comparison of MOOC and crowdsourcing phenomena along these salient dimensions. In doing so, we learn that both domains share further common traits, including similarities in IT structures, knowledge generating capabilities, presence of intermediary service providers, and techniques designed to attract and maintain participant activity. Stemming directly from this analysis, we discuss new directions for future research in both fields and draw out actionable implications for practitioners and researchers in both domains.
