Effective PSHE education: values, purposes and future directions

This article explores the perceived effectiveness of personal, social, health and economic (PSHE) education in primary and secondary schools. It outlines the relationship between perceived effectiveness and a range of explanatory factors, linking these to the values and ethos of schools, differing views of the purposes of PSHE education, and long-standing policy agendas. We conclude by attempting to locate PSHE education in the new and rapidly evolving policy context and discuss some potential ways forward, as established means of support and challenge disappear. The data utilised in the paper come from a mapping and effectiveness study of PSHE education in both primary and secondary schools throughout England, which was conducted by Sheffield Hallam University on behalf of the Department for Education

Loop corrections for Kaluza-Klein AdS amplitudes

Recently we conjectured the four-point amplitude of graviton multiplets in ${\rm AdS}_5 \times {\rm S}^5$ at one loop by exploiting the operator product expansion of $\mathcal{N}=4$ super Yang-Mills theory. Here we give the first extension of those results to include Kaluza-Klein modes, obtaining the amplitude for two graviton multiplets and two states of the first KK mode. Our method again relies on resolving the large N degeneracy among a family of long double-trace operators, for which we obtain explicit formulas for the leading anomalous dimensions. Having constructed the one-loop amplitude we are able to obtain a formula for the one-loop corrections to the anomalous dimensions of all twist five double-trace operators.Comment: 37 pages.

‘Boundary’: Mapping and Visualizing Climatically Changed Landscapes at Kaskawulsh Glacier and Kluane Lake, Yukon

This paper describes a collaboration between a visual artist and geoscientists, who together viewed the same rugged, high mountain landscape through different, yet complementary, lenses. We pair scientific mapping and historic comparative photography with a series of site-specific sculptural installations to interpret the dramatic geological changes that occurred at Kaskawulsh Glacier, Yukon, in the spring of 2016. In the summer of that year, artist K.A. Colorado accompanied geoscientists D.H. Shugar, J.J. Clague, and J.L. Best to the terminus of Kaskawulsh Glacier, as well as Kluane Lake downstream of the glacier, to document the landscape changes that occurred earlier in the year. The Boundary images were created as on-site, three-dimensional, artistic interpretations of the markedly changed boundaries that occurred as a result of climate-induced glacier retreat and the sudden subcontinental-scale reorganization of drainage. Both the scientific study conducted by the geomorphologists and the art installations created by the artist were performed simultaneously. The Boundary installation art project, together with satellite imagery and historical photographs, conveys the death of Slims River as a result of climate change

Frontiers in Earth Science, 7, (2019):58, doi:10.3389/feart.2019.00058.The early development and growth of oceanic volcanoes that eventually grow to become ocean islands are poorly known. In Hawai‘i, the submarine Lō‘ihi Seamount provides the opportunity to determine the structure and growth of such a nascent oceanic island. High-resolution bathymetric data were collected using AUV Sentry at the summit and at two hydrothermal vent fields on the deep south rift of Lō‘ihi Seamount. The summit records a nested series of caldera and pit crater collapse events, uplift of one resurgent block, and eruptions that formed at least five low lava shields that shaped the summit. The earliest and largest caldera, formed ∼5900 years ago, bounds almost the entire summit plateau. The resurgent block was uplifted slightly more than 100 m and has a tilted surface with a dip of about 6.5° toward the SE. The resurgent block was then modified by collapse of a pit crater centered in the block that formed West Pit. The shallowest point on Lō‘ihi’s summit is 986 m deep and is located on the northwest edge of the resurgent block. Several collapse events culminated in formation of East Pit, and the final collapse formed Pele’s Pit in 1996. The nine mapped collapse and resurgent structures indicate the presence of a shallow crustal magma chamber, ranging from depths of ∼1 km to perhaps 2.5 km below the summit, and demonstrate that shallow sub-caldera magma reservoirs exist during the late pre-shield stage. On the deep south rift zone are young medium- to high-flux lava flows that likely erupted in 1996 and drained the shallow crustal magma chamber to trigger the collapse that formed Pele’s Pit. These low hummocky and channelized flows had molten cores and now host the FeMO hydrothermal field. The Shinkai Deep hydrothermal site is located among steep-sided hummocky flows that formed during low-flux eruptions. The Shinkai Ridge is most likely a coherent landslide block that originated on the east flank of Lō‘ihi.Funding for the collection of the data was provided by the National Science Foundation OCE1155756 to CM and the Schmidt Ocean Institute to BG.

The definitive version was published in Oceanography 23, 1 (2010): 38-39.Axial Seamount is a hotspot volcano superimposed on the Juan de Fuca Ridge (JdFR) in the Northeast Pacific Ocean. Due to its robust magma supply, it rises ~ 800 m above the rest of JdFR and has a large elongate summit caldera with two rift zones that parallel and overlap with adjacent segments of the spreading center

Examining relationships between parent-reported factors and recurring ear symptoms among Aboriginal and Torres Strait Islander children

Issue addressed: Aboriginal and Torres Strait Islander child ear health is complex and multiple. We examined relationships between parent-reported sociodemographic, child health, health service access factors and ear symptoms among Aboriginal and Torres Strait Islander children aged 3 to 7 years. Methods: The Longitudinal Study of Indigenous Children is a large child cohort study with annual parent-reported data collection. Generalised linear mixed model analyses examined Wave 1 (1309 children 0-5 years; 2008) predictors of being free of parent-reported ear symptoms in both Waves 2 and 3. Results: A total of 1030 (78.7%) had no reported ear symptoms in either Wave 2 or 3. In the fully adjusted model, children who had been hospitalised in the past year (aOR = 2.16; 95% CI 1.19-3.93) and those with no ear symptoms (aOR = 2.94; 95% CI, 1.59-5.46) at Wave 1 had higher odds of no ear symptoms in both the subsequent waves. There were also relationships between parent main source of income–government pension or allowance as well as parents who reported no history of their own ear symptoms and higher odds of no ear symptoms in Waves 2 and 3 after partial adjustment for sociodemographic factors. Conclusion: These findings suggest relationships between different sociodemographic and health factors and parent-reported ear symptoms among Aboriginal and Torres Strait Islander children that warrant further investigation. So what? Children with parent-reported ear symptoms during the early years need holistic support to prevent future ear symptoms that impact health, social and educational life trajectories

GT2004-53704 CHEMICAL KINETIC MODELLING OF THE EVOLUTION OF GASEOUS AEROSOL PRECURSORS WITHIN A GAS TURBINE ENGINE

ABSTRACT A sequence of kinetic models has been developed to simulate the chemical processes occurring throughout the hot section of a modern gas turbine engine. The work was performed as part of the EU funded PARTEMIS programme, which was designed to investigate the effect of both engine condition and fuel sulphur content on the production of gaseous aerosol precursors such as SO 3 , H 2 SO 4 and HONO. For the PARTEMIS programme, a Hot End Simulator (HES) was designed to recreate the thermodynamic profile through which the hot gases pass after leaving the combustor. Combustion rig tests were performed in which the concentrations of gaseous product species were measured at the exits of both the combustor and the HES. These measurements were used to validate the kinetic models. The combustor was modelled by a sequence of five perfectly stirred reactors, using the Combustor Model Interface (CMI) developed at the University of Leeds. The CMI allows for the addition of dilution air at each stage of the combustor as well as re-circulation between each stage. The results at the combustor exit were then used as initial boundary conditions for the HES model, which followed the evolution of reacting gases through each of the pressure stages of the HES. This combination of the two models allowed the chemistry occurring throughout an engine, from combustor inlet to turbine exit, to be simulated. The principal aim of this modelling programme was to determine the extent of conversion of the sulphur (IV) species, SO 2 , to the sulphur (VI) species, SO 3 and H 2 SO 4 . The predicted level of this conversion at the exit of the HES was found to be in very good agreement with the experimentally measured values. These values were lower than had been previously determined by modelling studies and this was found to result from changes made to the thermodynamic properties of the key intermediate, HOSO 2 , following recent experimental measurements. The results also showed that for these tests, the predominant sulphur conversion process occurred within the combustor itself rather than the turbine or beyond
