    Stories of science: an auto/biographical study in primary science

    Get PDF
    This auto/biographical study examines a current dominant narrative within primary science. This concerns the often-reported connexion between subject knowledge and the impact this has on teacher confidence and consequently to pupils’ attitudes to science and to the pipeline of potential future scientists. A detailed analysis of the primary science literature and reports such as Wellcome Trust (2017) has questioned this link. Using an auto/biographical approach enabled me to utilise the personal narratives of successful science educators by listening to, and discussing with them, their life stories of science. These stories demonstrated their understanding of effective primary science teaching. Importantly, differences emerged, which related to individual understandings of the nature of science. Consequently, teachers who receive advice from these educators are provided with diverse interpretations of effective science teaching. Hearing these stories led me to also question my own beliefs of science, particularly how knowledge is created and shared. I undertook this development using Living theory as a frame. (Whitehead, 1987). As a result, two models were created to support the analysis; the first dealt with the classification of knowledge, a Horizontal and Vertical Structure of knowledge (HVSK) and the second focused on knowledge construction, the Sphere of Knowledge Construction (SKC). The recommendations from this thesis apply equally to qualified teachers and those training to be teachers. Firstly, models of knowledge classification should be used to discuss individual knowledge creation in initial and continuing teacher education. Secondly, stories of the sciences should play a central role in understanding the problems and the challenges that are inherent in the creation of understanding. Thirdly, opportunities should be provided for teachers and student teachers to be supported in science by significant others through practitioner-expert communities. Fourthly, research should be carried out into approaches that provide access to the stories of science without enforcing a science worldview

    Getting what you deserve: How notions of deservingness feature in the experiences of employees with cancer

    This article extends deservingness debates in social welfare to a new domain by exploring how deservingness features in the experiences of people who are in paid work when diagnosed with cancer. In doing so, it explores the interrelationship between deservingness criteria and Parsons' sick role. Narrative interview data was collected from people with cancer who were employed when they were diagnosed (n = 14) and line managers with experience of managing an employee with cancer (n = 7). Semi-structured interviews were conducted with members of occupational health and human resources staff (n = 3), health care professionals (n = 5) and staff from a UK cancer support charity (n = 7). Data was analysed thematically. Deservingness featured, and mattered, in how participants understood cancer in relation to work, and ensuing workplace interactions. Though cancer was generally seen as deserving; employees with cancer were perceived to be in need, and not blamed for their condition, this deservingness was subject to question. Employees with cancer were not necessarily considered equally deserving, dependent on their contribution as workers pre-diagnosis, and their efforts to contribute since being diagnosed. In a reflection of the fixed-term, time constricted nature of the sick role, work and welfare institutions required a definite timeline for employees to return to, or depart from work. The paper evidences an important gap between the fixed sick role as perceived by employers and the UK state welfare system, and the complex experiences of people diagnosed with cancer when in paid work

    The underrepresented French Trombone: A recording and written document of rarely performed 20th century Trombone literature of the Paris Conservatory

    Get PDF
    The purpose of this project was to highlight some of the lesser-known trombone solos within the oeuvre of the Paris Conservatory Solo de Concours (Solo Contest). While the output of solo works through the Paris Conservatory has been well documented for over a century-and-a-half, there are numerous compositions that have not reached the canonical status of the works of Tomasi, Guilmant, Castérède, and others. Several Prix de Rome winners composed for the trombone as a solo instrument; among them are Alfred Bachelet, Henri Büsser, Jules Mazellier, Raymond Loucheur, Yvonne Desportes and Claude Pascal. Regrettably, no reference recordings exist for many of the trombone solos written as contest pieces for the Paris Conservatory, including those composed by winners of the Prix de Rome. This project maintains a two-fold goal of recording an album of previously unrecorded trombone works from twentieth-century France, and providing a written document to include composer biographies and relevant information about the works performed

    The age of austerity: the impact of welfare reform on people in the North East of England

    According to Mark Carney the Governor of the Bank of England the United Kingdom economic outlook is getting brighter: "For the first time in a long time you don’t have to be an optimist to see the glass is half full. The recovery has finally taken hold (Carney 2013).” Unemployment is falling; as have interest rates and GDP (Gross Domestic Product) growth has been upgraded from 2.5 per cent to 2.8 per cent for the year 2014. Despite these “green shoots of recovery”, the impact of government austerity measures and social policy decisions means the outlook for millions of citizens remains blea

    Black Hole Remnants at the LHC

    Get PDF
    Within the scenario of large extra dimensions, the Planck scale is lowered to values soon accessible. Among the predicted effects, the production of TeV mass black holes at the {\sc LHC} is one of the most exciting possibilities. Though the final phases of the black hole's evaporation are still unknown, the formation of a black hole remnant is a theoretically well motivated expectation. We analyze the observables emerging from a black hole evaporation with a remnant instead of a final decay. We show that the formation of a black hole remnant yields a signature which differs substantially from a final decay. We find the total transverse momentum of the black hole event to be significantly dominated by the presence of a remnant mass providing a strong experimental signature for black hole remnant formation

    The Distance to the Vela Supernova Remnant

    Get PDF
    We have obtained high resolution Ca II and Na I absorption line spectra toward 68 OB stars in the direction of the Vela Supernova Remnant. The stars lie at distances of 190 -- 2800 pc as determined by Hipparcos and spectroscopic parallax estimations. The presence of high velocity absorption attributable to the remnant along some of the sight lines constrains the remnant distance to 250+/-30 pc. This distance is consistent with several recent investigations that suggest that the canonical remnant distance of 500 pc is too large.Comment: To be published in The Astrophysical Journal Letters Figure 1 y-axis labels correcte

    The Re-Acceleration of the Shock Wave in the Radio Remnant of SN 1987A

    We report on updated radio imaging observations of the radio remnant of Supernova 1987A (SN 1987A) at 9 GHz, taken with the Australia Telescope Compact Array (ATCA), covering a 25-year period (1992-2017). We use Fourier modeling of the supernova remnant to model its morphology, using both a torus model and a ring model, and find both models show an increasing flux density, and have shown a continuing expansion of the remnant. As found in previous studies, we find the torus model most accurately fits our data, and has shown a change in the remnant expansion at Day 9,300 ±\pm210 from 2,300 ±\pm200 km/s to 3,610 ±\pm240 km/s. We have also seen an increase in brightness in the western lobe of the remnant, although the eastern lobe is still the dominant source of emission, unlike what has been observed at contemporary optical and X-ray wavelengths. We expect to observe a reversal in this asymmetry by the year \sim2020, and note the south-eastern side of the remnant is now beginning to fade, as has also been seen in optical and X-ray data. Our data indicate that high-latitude emission has been present in the remnant from the earliest stages of the shockwave interacting with the equatorial ring around Day 5,000. However, we find the emission has become increasingly dominated by the low-lying regions by Day 9,300, overlapping with the regions of X-ray emission. We conclude that the shockwave is now leaving the equatorial ring, exiting first from the south-east region of the remnant, and is re-accelerating as it begins to interact with the circumstellar medium beyond the dense inner ring.Comment: 22 pages, 14 figures.

    Radiation of Angular Momentum by Neutrinos from Merged Binary Neutron Stars

    We study neutrino emission from the remnant of an inspiraling binary neutron star following coalescence. The mass of the merged remnant is likely to exceed the stability limit of a cold, rotating neutron star. However, the angular momentum of the remnant may also approach or even exceed the Kerr limit, J/M^2 = 1, so that total collapse may not be possible unless some angular momentum is dissipated. We find that neutrino emission is very inefficient in decreasing the angular momentum of these merged objects and may even lead to a small increase in J/M^2. We illustrate these findings with a post-Newtonian, ellipsoidal model calculation. Simple arguments suggest that the remnant may form a bar mode instability on a timescale similar to or shorter than the neutrino emission timescale, in which case the evolution of the remnant will be dominated by the emission of gravitational waves.Comment: 12 pages AASTeX, 2 figures, to appear in Ap
