description: In this paper, the availability of multi-wavelength optical/infrared information of FIRST (Faint Images of the Radio Sky at 20 cm) radio sources counterparts over ~9.2 deg^{2} in Bootes field and ~2.4 deg^{2} in Cetus field is exploited to infer the physical properties of the faint radio population. The radio sources optically identified have been divided into resolved galaxies and stellar-like objects finding that the faint radio population is mainly composed of early-type galaxies with very red colour (Bw-R~4.6). A total number of 57 counterparts of FIRST radio sources have extremely red colour (R-K>5). Photometric redshift from Hyperz implies that the Extremely Red Objects (EROs) counterparts to FIRST radio sources are mostly located in the range z=0.7-2, with the bulk of the population at z\sim 1. Taking advantage of the near infrared imaging with FLAMEX (FLAMINGOS Extragalactic Infrared Survey), the EROs counterparts to FIRST radio sources are separated into passively-evolving and dusty star-forming galaxies using their RJK colours; the relatively blue J-K of these galaxies suggest that most are old elliptical galaxies (18/25) rather than dusty starburst (7/25). A total of 15 Distant Red Galaxy (DRGs) have been identified as counterparts to FIRST radio sources in Cetus field and 3 DRGs in Boötes field with J-K>2.3.

Modelling stellar coronae from surface magnetograms: the role of missing magnetic flux

description: Recent advances in spectropolarimetry have allowed the reconstruction of stellar coronal magnetic fields. This uses Zeeman-Doppler magnetograms of the surface magnetic field as a lower boundary condition. The ZDI maps, however, suffer from the absence of information about the magnetic field over regions of the surface due to the presence of dark starspots and portions of the surface out of view due to a tilt in the rotation axis. They also suffer from finite resolution which leads to small scale field structures being neglected. This paper explores the effects of this loss of information on the extrapolated coronal fields. For this we use simulated stellar surface magnetic maps for two hypothetical stars. Using the potential field approximation, the coronal fields and emission measures are calculated. This is repeated for the cases of missing information due to, (i) starspots, (ii) a large area of the stellar surface out of view, (iii) a finite resolution. The largest effect on the magnetic field structure arises when a significant portion of the stellar surface remains out of view. This changes the nature of the field lines that connect to this obscured hemisphere. Nonetheless, the field structure in the visible hemisphere is reliably reproduced. Thus the calculation of the locations and surface filling factors of accretion funnels is reasonably well reproduced for the observed hemisphere. The decrease with height of the magnetic pressure, which is important in calculating disc truncation radii for accreting stars, is also largely unaffected in the equatorial plane. The fraction of surface flux that is open and therefore able to supply angular momentum loss in a wind, however, is often overestimated in the presence of missing flux.

description: This phenomenological approach to emotions emphasizes the fundamental impor­tance of the realm of feeling in both the cognitive and practical exercise of reason. It outlines a general theory of feeling, which exploits a classical phenomenological anal­ysis of emotional intentionality as the mode of presence and experience of values to provide a taxonomy of emotional states and acts. It also aims to connect the two levels of affective sensibility apparently concerned: one that is basically embodied, and one that is cognitively of a “higher” level, involved in a large variety of acts and behaviors characteristic of a rational and moral agent – such as a human being.

description: (Abridged) In this second paper of the series, we present the results from optical Gemini-North GMOS-IFU and WIYN DensePak IFU spectroscopic observations of the starburst and inner wind zones of M82, with a focus on the state of the T~10^4 K ionized interstellar medium. Our electron density maps show peaks of a few 1000 cm-3, local small spatial-scale variations, and a fall-off in the minor axis direction. We discuss the implications of these results with regards to the conditions/locations that may favour the escape of individual cluster winds. Our findings imply that the starburst environment is highly fragmented into a range of clouds from small/dense clumps with low filling factors (<1pc, n_e>10^4 cm-3) to larger filling factor, less dense gas. The near-constant state of the ionization state of the ~10^4 K gas throughout the starburst can be explained as a consequence of the small cloud sizes, which allow the gas conditions to respond quickly to any changes. We have examined in more detail both the broad (FWHM 150-350 km/s) line component found in Paper I that we associated with emission from turbulent mixing layers on the gas clouds, and the discrete outflow channel identified within the inner wind. The channel appears as a coherent, expanding cylindrical structure of length >120 pc and and width 35-50 pc and the walls maintain an approximately constant (but subsonic) expansion velocity of ~60 km/s. We use the channel to examine further the relationship between the narrow and broad component emitting gas within the inner wind. Within the starburst energy injection zone, we find that turbulent motions (as traced by the broad component) appear to play an increasing role with height.

Effects of Second Language Learning on First Language English Skills: Southern Tasmanian Teacher Perceptions
Creators: name: Jensen, RE
Publisher: name: University Of Tasmania
Year: 2023

description: This research examined the following question: What effects do Southern Tasmanian English teachers perceive second language learning to have on high-school students' first language English skills?‚ÄövÑvp This focus was chosen to reflect the researcher's interest in second language (L2) learning, which was inspired by observing improvements in first language (L1) English skills as a result of L2 learning from personal experience. In order to establish whether other L2 students in Southern Tasmania experienced a similar effect, high-school English teachers were interviewed and asked to comment on the effects they had noticed (if any) in their students. From the data collected, it appears that the researcher is not alone in experiencing benefits to L1 English as a result of L2 learning. In particular, teacher participants observed that their students experienced positive linguistic effects to their L1 grammar, vocabulary and awareness of language, and positive non-linguistic effects in the areas of cultural awareness and improved work ethic. These findings outline some of the benefits of L2 learning on L1, and provide an argument for continuing (and even possibly increasing) L2 learning opportunities in schools.

description: We suggest a theory of the Field-Induced Charge-Density-Wave (FICDW) phases, generated by high magnetic fields in quasi-low-dimensional conductors. We demonstrate that, in layered quasi-one-dimensional conductors, the corresponding critical magnetic fields ratios are universal and do not depend on any fitting parameter. In particular, we find that $H_1/H_0 = 0.73, \ H_2/H_0 = 0.59, H_3/H_0 = 0.49, H_4/H_0 = 0.42$, where $H_n$ is a critical field of a phase transition between the FICDW phases with numbers $n$ and $n+1$. The suggested theory is in very good qualitative and quantitative agreements with the existing experimental data in $α$-(ET)$_2$KHg(SCN)$_4$ material.

Individuelle Lebensordnung und Weltbezug. Die Frage nach der Ordnung des „Guten Lebens“ in Schelers Ordo Amoris

description: The notion that there are ordering structures in the world was first developed in an­cient Greek thought. This notion of ordering structures can be found in the epics of Homer and Hesiod, in the Greek lyricists, and in the Attic dramas, and it is transformed and reformulated through the philosophical reflections starting with Heraclitus and ending with Aristotle. As a consequence, the region for which an ordering is possible becomes ever broader. Initially, this region was the world and its origination, but then it grew to include human beings and their thoughts, feelings and actions. Not only were orderings considered to be already present in the world, but the human being was placed in the position to emulate and bring them about. Yet, the very possibility of dynamic representations of ordering is called into question by the possible reconstruction of ordering and by the possible inner transformation that can take place through action and the reshaping of the world. If a system is established by the representation of an ordering, would not any transformation disturb the ordering? It is in particular this old question that is raised anew when Max Scheler introduces his concept of ordering, an ordo amoris: how can education, edification, action, responsibility, etc., be possible, if perception or value-ception, intentional acts that the individual executes and that establish the foundational order, have a rigid foundational order? This problem directly concerns the concept of norms and their relation to the representation of ordering. A further problem arises thereby in Scheler when the relation between the objective measures of a binding ordo amoris, which determines the value goodness of every possible striving, and the subjective framework of the individual order of preference is called into question.

Get moving in maths : engaging students in active mathematical experiences
Creators: name: Gleadow, JL
Publisher: name: University Of Tasmania
Year: 2023

description: Rates of student participation in mathematics are declining, especially at the tertiary level, where in some states in Australia students' have the option to choose mathematics. Recent research also suggests that students as young as nine are expressing negative feelings towards mathematics (Larkin & Jorgensen, 2015). A recommendation from researchers is to enable teachers of mathematics to implement pedagogical strategies, which engage students. The aim of this research project was to investigate whether there is a link between purposeful movement within mathematics and an increase in overall student engagement. This was investigated from the perspectives of both the participating teacher and her class of Grade 1 students. The results showed that students were highly affectively engaged in mathematics learning when movement was present. In fact, one of the main findings of this study was the high level of interest and very low levels of frustration identified by the participating students when undertaking mathematical activities. This is of relevance for educational professionals as it suggests that purposeful movement within mathematics has the potential to increase interest and decrease frustration, which could be a factor in slowing the decline of engagement in mathematics.

description: Robust galaxy cluster mass estimates are fundamental for constraining cosmological parameters from counts. For this reason, it is essential to search for tracers that, independent of the cluster's dynamical state, have a small intrinsic scatter and can be easily inferred from observations. This work uses a simulated data set to focus on photometric properties and explores different optical mass proxies including richness, optical luminosity, and total stellar mass. We have developed a probabilistic membership assignment that makes minimal assumptions about the galaxy cluster properties, limited to a characteristic radius, velocity dispersion, and spatial distribution. Applying the estimator to over 919 galaxy clusters with $z_{phot}<$0.45 within a mass range of $10^{12.8}$ to $10^{15}$ M$_\odot$, we obtain robust richness estimates that deviate from the median true value (from simulations) by -0.01$ \pm $0.12. The scatter in the mass-observable relations is $σ_{log_{10}(M|\mathcal{R})}=$0.181 $\pm$ 0.009 dex for richness, $σ_{log_{10}(M|L_λ)}=$0.151 $\pm$ 0.007 dex for optical luminosity, and $σ_{log_{10}(M|M_λ^*)}=$0.097 $\pm$ 0.005 dex for stellar mass. We also discuss membership assignment, completeness and purity, and the consequences of small centre and redshift offsets. We conclude that the application of our method for photometric surveys delivers competitive cluster mass proxies.

The Sociogenesis of the Informal Sector: A Case Study of Lilongwe Central Market

description: This thesis is entitled The Sociogenesis of the Informal Sector- A Case Study of Lilongwe Central Market. It seeks to answer the research question, what is the sociogenesis of the informal sector using Lilongwe Central Market as a case study. In this regard, it applies a synthetic approach between the theoretical frameworks of Fligstein and McAdam’s strategic action field (SAF) theory and Elias’ figurational sociology. The thesis concludes that the fire of 23 September 2016 signified a major milestone in the market’s sociogenesis. Fires have a fundamental impact on the figurational dynamics within the market, and contributes to a lessening of the power chances and cohesiveness of those in the market. After a market is burned down, cohesion in the market is weak and the market is vulnerable to exploitation. Lilongwe Central Market’s long and deep interdependencies made it resilient prior to, and after the fire. These interdependencies developed as a result of civilising processes arising from the market’s sociogenesis and aided it in its recovery.

Particle Acceleration in Relativistic Magnetized Collisionless Pair Shocks: Dependence of Shock Acceleration on Magnetic Obliquity
Creators: name: Sironi, Lorenzo

Publisher: name: arXiv

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We investigate shock structure and particle acceleration in relativistic magnetized collisionless pair shocks by means of 2.5D and 3D particle-in-cell simulations. We explore a range of inclination angles between the pre-shock magnetic field and the shock normal. We find that only magnetic inclinations corresponding to "subluminal" shocks, where relativistic particles following the magnetic field can escape ahead of the shock, lead to particle acceleration. The downstream spectrum in such shocks consists of a relativistic Maxwellian and a high-energy power-law tail with exponential cutoff. For increasing magnetic inclination in the subluminal range, the high-energy tail accounts for an increasing fraction of particles (from ~1% to ~2%) and energy (from ~4% to ~12%). The spectral index of the power law increases with angle from -2.8+-0.1 to -2.3+-0.1. Particle energization is driven by the Diffusive Shock Acceleration process for nearly parallel shocks, and switches to Shock-Drift Acceleration for larger subluminal inclinations. For "superluminal" shocks, the downstream particle spectrum does not show any significant suprathermal tail. As seen from the upstream frame, efficient acceleration in relativistic (Lorentz factor gamma0 > 5) magnetized (sigma > 0.03) flows exists only for a very small range of magnetic inclination angles (< 34/gamma0 degrees), so relativistic astrophysical pair shocks have to be either nearly parallel or weakly magnetized to generate nonthermal particles. These findings place constraints on the models of AGN jets, Pulsar Wind Nebulae and Gamma Ray Bursts that invoke particle acceleration in relativistic magnetized shocks. (Abridged)

Ascorbic acid production in the cultured tissue of the briar rose, rosa rugosa
Creators: name: Wegg, Susan Melanie
Publisher: name: University of British Columbia
Year: 2011

description: The fleshy hips of the briar rose, Rosa rugosa were cultured on a modified medium developed by Gamborg (1963) to produce callus and suspension cultures. These cells were very light, almost white. Reduced ascorbic acid, determined by the 2,6-dichlorophenolindophenol titration method, was found in the suspension cultures. This finding prompted an investigation into culture techniques for obtaining an optimum concentration of ascorbic acid. During the growth of the cells, the pH rose and ascorbic acid concentration increased after the sixth day. Age of culture was also an important factor as cultures older than three or four weeks contained virtually no ascorbic acid. Possible precursors of ascorbic acid in plants were added to cultures and their effect on the ascorbic acid level was determined over a period of twenty-four hours. D-glucose, D-(-)-levulose, D-galactose and D-glucurono-ɣ-lactone caused no increase. L-gulono-ɣ-lactone brought about a slight increase and a comparatively large increase was obtained with L-galactono-ɣ-lactone. Confirmation for the latter was obtained using the 2,4-dinitrophenylhydrazine method to rule out the possibility or microbial contamination and to be sure that another metabolite was not responsible for the increased reducing capacity of the system. Omission of myoinositol from the vitamin solution of the medium decreased total cell yield but had no effect on the level of ascorbic acid. Decreasing the sucrose content of the medium by one-half caused a sharp decrease in ascorbic acid concentration, indicating that an adequate supply of sugar is a prerequisite for optimum production of ascorbic acid. Growing liquid suspensions under controlled illumination resulted in increased ascorbic acid values with each successive transfer; however, total cell yields decreased each time. In addition, there was no evidence of chlorophyll production in the cultures. This exploratory work shows that ascorbic acid is present in the tissue culture of Rosa rugosa. Therefore, tissue culture may be useful for elucidating the complete pathway for ascorbic acid production which is as yet still unclear. This information coupled with the effects of altering the physical environment of the cells may direct cultures of Rosa rugosa to produce ascorbic acid in quantities that would make its recovery industrially attractive.

description: Data collected around sqrt{s}=91 GeV by the OPAL experiment at the LEP e+e- collider are used to study the mechanism of baryon formation. As the signature, the fraction of Sigma-hyperons whose baryon number is compensated by the production of a Sigma-, Lambda or Xi- antihyperon is determined. The method relies entirely on quantum number correlations of the baryons, and not rapidity correlations, making it more model independent than previous studies. The diquark fragmentation model without the popcorn mechanism is strongly disfavored with a significance of 3.8 standard deviations including systematic uncertainties. It is shown that previous studies of the popcorn mechanism are not conclusive if parameter uncertainties are considered.

We solve this initial value problem numerically for several cases, including unequal mass binary black holes with spins and boosts. The singularity at null infinity in the Hamiltonian constraint associated with a constant mean curvature hypersurface does not pose any particular difficulties. The inner boundaries of our slices are minimal surfaces. Trumpet configurations are explored both analytically and numerically.

description: The Versatile Video Coding (VVC) standard has been finalized by Joint Video Exploration Team (JVET) in 2020. Compared to the High Efficiency Video Coding (HEVC) standard, VVC offers about 50% compression efficiency gain, in terms of Bjontegaard Delta-Rate (BD-rate), at the cost of about 10x more encoder complexity. In this paper, we propose a Convolutional Neural Network (CNN)-based method to speed up inter partitioning in VVC. Our method operates at the Coding Tree Unit (CTU) level, by splitting each CTU into a fixed grid of 8x8 blocks. Then each cell in this grid is associated with information about the partitioning depth within that area. A lightweight network for predicting this grid is employed during the rate-distortion optimization to limit the Quaternary Tree (QT)-split search and avoid partitions that are unlikely to be selected. Experiments show that the proposed method can achieve acceleration ranging from 17% to 30% in the RandomAccess Group Of Picture 32 (RAGOP32) mode of VVC Test Model (VTM)10 with a reasonable efficiency drop ranging from 0.37% to 1.18% in terms of BD-rate increase.

description: Polymer networks consisting of a mixture of chemical and physical cross-links are known to exhibit complex time-dependent behaviour due to the kinetics of bond association and dissociation. In this article, we highlight and compare two recent physically based constitutive models which describe the nonlinear viscoelastic behaviour of such transient networks. These two models are developed independently by two groups of researchers using different mathematical formulations. Here, we show that this difference can be attributed to different viewpoints: Lagrangian versus Eulerian. We establish the equivalence of the two models under the special situation where chains obey Gaussian statistics and steady-state bond dynamics. We provide experimental data demonstrating that both models can accurately predict the time-dependent uniaxial behaviour of a poly(vinylalcohol) PVA dual cross-link hydrogel. We review the advantages and disadvantages of both approaches in applications and close by discussing a list of open challenges and questions regarding the mathematical modelling of soft, viscoelastic networks.

description: The $(3 + 1)$-dimensional (generalized) Dirac equation is shown to have the same form as the equation expressing the condition that a given point lies on a given line in 3-dimensional projective space. The resulting Hamiltonian with a $γ_5$ mass term is not Hermitian, but is invariant under the combined transformation of parity reflection $\cal P$ and time reversal $\cal T$. When the $\cal PT$ symmetry is unbroken, the energy spectrum of the free spin-$\frac {1}{2}$ theory is real, with an appropriately shifted mass.

description: Exploring for the Future (EFTF) is an Australian Government program led by Geoscience Australia (GA), in partnership with state and Northern Territory governments. The EFTF program (2016-2024) aims to drive industry investment in resource exploration in frontier regions of onshore Australia by providing new precompetitive data and information about their energy, mineral and groundwater resource potential.
Under the EFTF program, the Basin Inventory Project undertook a study of petroleum prospectivity of the onshore Eromanga Basin in Queensland and South Australia. Yongala 1 well in Queensland was selected based on the occurrence of gas and oil shows reported in the well completion report. Sampling of cuttings and cores was done at Geoscience Australia's Petroleum Data Repository in Canberra.
Geoscience Australia commissioned a fluid inclusion stratigraphy (FIS) study on the downhole samples. Here, volatile components ostensibly trapped with fluid inclusions are released and analysed revealing the level of exposure of the well section to migrating fluids. Integration of thin section (TS) preparations reveal the extent of gas and fluid trapping within fluid inclusions while microthemometry (MT) gives an estimation of fluid inclusion trapping temperature.
For Yongala 1, FIS analysis was performed on 418 cuttings and 52 cores between 15.2 metres and 3104.5 metres base depth, together with 22 samples prepared for TS and 3 samples for MT. To support this study, lithostratigraphic tops were compiled by Geoscience Australia. The results of the study are found in the accompanying documents.

Paternity and the quest for knowledge in the works of Joyce and Proust
Creators: name: Mackenzie, Susan Jane
Publisher: name: University of British Columbia
Year: 2011

description: The general theme of this thesis is Paternity and the Search for Knowledge in the works of James Joyce and Marcel Proust, specifically, in A Portrait of the Artist as a Young Man, Ulysses, and A la Recherche du Temps Perdu. Two main sets of characters are compared in the novels; the young artists, or would-be artists, Stephen and Marcel, and the older, experienced men-of-the-world who become their mentors, Bloom and Swann. Both young artists must overcome a fear of the physical world which tends to make them ineffectual dreamers, self-romanticizers. Stephen has been taught to deny the physical side of his nature by family and society. Marcel's fear of suffering and overdependence on others also has its origin in his family life. Neither young poet can create until he has been immersed in the physical experience of life, and has attained that knowledge of good and evil in himself and others which is the goal of his quest. Bloom and Swann are ‘father-figures’ in two senses; they 'educate' the young lads by initiating them into life, and they are themselves very much involved in the cycles of physical creation. Their roles are discussed in the light of various mythologies; specifically; Classical, Medieval, and Jewish. An intensive study of flower imagery in the three novels helps to elucidate further their roles as 'Earth-Fathers.'

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
