Visual Literacy and New Technologies

This body of research addresses the connection between arts, identity and new technology, and investigates the impact of images on adolescent identities, the relationship between online modes of communication and cyber-bullying, the increasing visualization of information and explores the way drawing and critical analysis of imagery develops visual literacy. Commissioned by Adobe Systems Pty Ltd, Australia (2003) to compile the Visual Literacy White Paper, Bamford’s report defines visual literacy and highlights its importance in the learning of such skill as problem solving and critical thinking. Providing strategies to promote visual literacy and emphasizing the role of technology in visual communication, this report has become a major reference for policy on visual literacy and cyber-bullying in the UK, USA and Asia

GPS Based Autonomous Navigation Study for the Lunar Gateway

This paper describes and predicts the performance of a conceptual autonomous GPS-based navigation system for NASA's planned lunar Gateway. This system is based on the flight-proven Magnetospheric Multiscale (MMS) GPS navigation system, augmented with an earth-pointed high-gain antenna and with an option for an atomic clock. High-fidelity simulations, calibrated against MMS flight data and making use of GPS transmitter patterns from the GPS Antenna Characterization Experiment (ACE) project are developed for operation of the system in the Gateway Near-Rectilinear Halo Orbit (NRHO). The results indicate that GPS can provide an autonomous, realtime navigation capability with comparable, or superior, performance to traditional Deep Space Network approach with eight hours of tracking per day

The Wow and the How: The role of arts education and approaches for teaching

Society is facing considerable disruptions. To name but a few we have seismic changes in technology, in the nature of work, in the environment, in inequality, in patterns of life and migration, in health and wellbeing, and in the mistrust of institutions. Above all, we have become increasingly at the mercy of very rapid changes. The arts, and specifically arts education, help to prepare us to learn and to flourish in the world now and in the future. El artículo revisa los aportes de la educación artística a la formación de las personas.  A partir del estudio internacional sobre el impacto de las artes en la educación, encomendado por UNESCO, explicita sus observaciones sobre aspectos vitales para una buena práctica   en la enseñanza de las artes. Discute también algunas creencias y preocupaciones de los profesores de arte y propone un abordaje integrador, denominado Fusion Aproach que armoniza tanto la experiencia del descubrimiento y el asombro (factor wuau!!!)  como la necesidad de desarrollar habilidades específicas de los lenguajes artísticos (el cómo hace). Aborda el papel mediador del docente en las prácticas culturale

Galaxy And Mass Assembly (GAMA) : stellar mass functions by Hubble type

This work was supported by the Austrian Science Foundation FWF under grant P23946. AWG was supported under the Australian Research Council's funding scheme FT110100263.We present an estimate of the galaxy stellar mass function and its division by morphological type in the local (0.025 < z < 0.06) Universe. Adopting robust morphological classifications as previously presented (Kelvin et al.) for a sample of 3727 galaxies taken from the Galaxy And Mass Assembly survey, we define a local volume and stellar mass limited sub-sample of 2711 galaxies to a lower stellar mass limit of M = 109.0 MΘ. We confirm that the galaxy stellar mass function is well described by a double-Schechter function given by Μ* = 1010.64 MΘ, α1 = 0.43, φ1* = 4.18 dex-1 Mpc-3, α2 = −1.50 and φ2* = 0.74 dex-1 Mpc-3. The constituent morphological-type stellar mass functions are well sampled above our lower stellar mass limit, excepting the faint little blue spheroid population of galaxies. We find approximately 71-4+3 per cent of the stellar mass in the local Universe is found within spheroid-dominated galaxies; ellipticals and S0-Sas. The remaining 29-3+4 per cent falls predominantly within late-type disc-dominated systems, Sab-Scds and Sd-Irrs. Adopting reasonable bulge-to-total ratios implies that approximately half the stellar mass today resides in spheroidal structures, and half in disc structures. Within this local sample, we find approximate stellar mass proportions for E : S0-Sa : Sab-Scd : Sd-Irr of 34 : 37 : 24 :5.Publisher PDFPeer reviewe

Who’s in? Analysing the impact of inclusive communication policy and processes on organisations seeking to include diverse publics

University of Technology Sydney. Faculty of Arts and Social Sciences.Many organisations acknowledge the need to include diverse publics, but most struggle to do so. A case study approach investigated an organisation from each of the not-for-profit, government, and for-profit sectors with a reputation for including diverse publics. Each organisation’s inclusive policies and processes from 2008-2019 were analysed and interviews held with their publics with disability and from a Non-English-Speaking Background (NESB) between 2017-2018. A mismatch between the diverse publics’ norms of culture and the organisations’ norms of practice was found. Gaps in communication processes prevented effective feedback mechanisms to inform change; business goals took priority over mission statements supporting the values of inclusion; and the lack of relationships with advocacy groups left NESB publics with no one to speak for them. Staff with lived experience of disability or as a NESB shared some of these publics’ norms of culture but they were unable to use this understanding to influence the organisations’ norms of practice. The study demonstrated that strategic communication processes could improve inclusion of diverse publics. A key conceptual contribution of this study is the observation that embedding strategic communication processes to build on Habemas’s ideological framework of communicative action leads to new knowledge and understanding for organisations, through support for an open exchange of ideas with diverse publics. Four significant implications for practice were identified: establishing feedback mechanisms on inclusion is important for understanding current needs and promoting future services; communicating with diverse publics requires specialist skills; programs of education for strategic communicators need an emphasis on establishing processes that bring together the norms of culture of diverse publics with the potentially constraining norms of practice of organisations; the changes required in organisations to ensure that diverse publics are included need to focus on access, requiring the implementation of culturally sensitive strategic communication processes. This study’s originality lies in its close study of mainstream organisations widely regarded as industry leading in relation to their inclusive approach to diverse publics. It revealed practices that covertly excluded diverse publics, and identified staff were unaware

Development of fluorophore-tagged DNA probes for cellular imaging applications

Single nucleotide polymorphisms (SNPs) are single base variations in DNA which give genetic variation. However, SNPs can also be linked to the development of certain diseases. Modified oligonucleotides used to probe biological changes and processes have become an important focus of scientific research. Fluorescent tagging of DNA can be used to sense SNPs in DNA targets through differences in emission intensity on the formation of a duplex. An anthracene-tagged DNA probe developed by Tucker $et$ $al$. is able to discriminate between a fully complementary DNA target sequence and one with a single base difference. This thesis describes how SNP sensing with anthracene-tagged DNA has been extended to SNPs in RNA targets and sequences associated with Alzheimer's disease. Finally, a new dual fluorophore DNA probe was designed for SNP sensing via FRET

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Galaxy and Mass Assembly (GAMA): Variation in Galaxy Structure Across the Green Valley

Using a sample of 472 local Universe (z < 0.06) galaxies in the stellar mass range 10.25 < log M*/MG < 10.75, we explore the variation in galaxy structure as a function of morphology and galaxy colour. Our sample of galaxies is sub-divided into red, green and blue colour groups and into elliptical and non-elliptical (disk-type) morphologies. Using KiDS and VIKING derived postage stamp images, a group of eight volunteers visually classified bars, rings, morphological lenses, tidal streams, shells and signs of merger activity for all systems. We find a significant surplus of rings (2.3σ) and lenses (2.9σ) in disk-type galaxies as they transition across the green valley. Combined, this implies a joint ring/lens green valley surplus significance of 3.3σ relative to equivalent disk-types within either the blue cloud or the red sequence. We recover a bar fraction of ∼ 44% which remains flat with colour, however, we find that the presence of a bar acts to modulate the incidence of rings and (to a lesser extent) lenses, with rings in barred disk-type galaxies more common by ∼ 20 − 30 percentage points relative to their unbarred counterparts, regardless of colour. Additionally, green valley disk-type galaxies with a bar exhibit a significant 3.0σ surplus of lenses relative to their blue/red analogues. The existence of such structures rules out violent transformative events as the primary end-of-life evolutionary mechanism, with a more passive scenario the favoured candidate for the majority of galaxies rapidly transitioning across the green valley. Key words: galaxies: elliptical and lenticular, cD – galaxies: spiral – galaxies: evo- lution – galaxies: star formation – galaxies: statistics – galaxies: structur
