    We explore how story has the potential to encourage environmental engagement and a sense of agency provided that critical discussion takes place. We illuminate this with reference to the philosophies of John Macmurray on personal agency and social relations; of John Dewey on the primacy of experience for philosophy; and of Paul Ricoeur on hermeneutics, dialogue, dialectics and narrative. We view the use of fiction for environmental understanding as hermeneutic, a form of conceptualising place which interprets experience and perception. The four writers for young people discussed are Ernest Thompson Seton, Kenneth Grahame, Michelle Paver and Philip Pullman. We develop the concept of critical dialogue, and link this to Crick's demand for active democratic citizenship. We illustrate the educational potential for environmental discussions based on literature leading to deeper understanding of place and environment, encouraging the belief in young people that they can be and become agents for change. We develop from Zimbardo the key concept of heroic resister to encourage young people to overcome peer pressure. We conclude with a call to develop a greater awareness of the potential of fiction for learning, and for writers to produce more focused stories engaging with environmental responsibility and activism

    Chemistry: The essential spark for engagement

    Living in a socially deprived area can be tough. At least, that’s what several recent reports looking at the secondary school experience of teenagers in this demographic have indicated. it is recognised that the UK economy needs a highly skilled workforce and, in the North West, we have a large employer base of biochemical and chemical companies (see www. chemicalsnorthwest. org.uk), so we need school pupils from all backgrounds to be scientifically literate. Those who grow up in a socially deprived group are less likely to pursue careers involving science than the general population

    Teachers’ perception of chemistry outreach work, especially in the context of children’s social demography

    The aim of this current research is to investigate teachers’ perceptions of the purpose and impact of chemistry/science outreach work. Considering views of educators, both in training and practice, is an important area to explore as teachers are the gatekeepers to these experiences and consciously or subconsciously have their own views about the value of these programmes. In addition, the teacher can influence a child’s view of their scientific ability which can potentially inform an individual’s decisions and perceptions regarding science as a career. It is necessary for a teacher to be aware of their pivotal role within the classroom and how their own ‘habitus’ may have an impact on those whom they teach. This pilot study was an illustrative exercise to analyse a small sample of data and provide a focus for a subsequent main data collection where the level of response will be much higher. The study sought to answer the following question; what do teachers in the North-West of England think about chemistry based outreach programmes, especially in the context of children’s social demography? However, no ‘conclusions’ or generalisations are derived from this small sample itself, only emerging themes are discussed. These themes highlight how teachers may perceive chemistry/science outreach to be of greater importance the higher the educational level and how these programmes may provide experiences and opportunities for students from a lower socio-economic background

    Research Focus: Nurturing socio-economically challenged learners' curiosity in chemistry

    It is understood that ‘active learning’, in which students participate in their own learning, is effective in developing understanding (Michael & Modell, 2003). Students are likely to engage well in lessons that require participation and that challenge them to develop their understanding through hands-on experience (Koballa & Glynn, 2007). Learning outcomes are enhanced when enjoyment is high. This has been a cornerstone of Liverpool John Moores University’s programme of interventions delivered for the Royal Society of Chemistry project, Chemistry for All (CfA)

    A Suite of Early Eocene (~55 Ma) Climate Model Boundary Conditions

    Get PDF
    We describe a set of early Eocene (~ 55 Ma) climate model boundary conditions constructed in a self-consistent reference frame and incorporating recent data and methodologies. Given the growing need for uniform experimental design within the Eocene climate modelling community and the challenges faced in simulating the prominent features of Eocene climate, we make publicly available our data sets of Eocene topography, bathymetry, tidal dissipation, vegetation, aerosol distributions and river runoff. Major improvements in our boundary conditions over previous efforts include the implementation of the ANTscape palaeotopography of Antarctica, more accurate representations of the Drake Passage and Tasman Gateway, as well as an approximation of sub grid cell topographic variability. Our boundary conditions also include for the first time modelled estimates of Eocene aerosol distributions and tidal dissipation, both consistent with our palaeotopography and palaeobathymetry. The resolution of our data sets is unprecedented and will facilitate high resolution climate simulations. In light of the inherent uncertainties involved in reconstructing global boundary conditions for past time periods these data sets should be considered as one interpretation of the available data and users are encouraged to modify them according to their needs and interpretations. This paper marks the beginning of a process for reconstructing a set of accurate, open-access Eocene boundary conditions for use in climate models

    Ridge subduction sparked reorganization of the Pacific plate-mantle system 60-50 million years ago

    Get PDF
    A reorganization centered on the Pacific plate occurred ~53–47 million years ago. A “top-down” plate tectonic mechanism, complete subduction of the Izanagi plate, as opposed to a “bottom-up” mantle flow mechanism, has been proposed as the main driver. Verification based on marine geophysical observations is impossible as most ocean crust recording this event has been subducted. Using a forward modeling approach, which assimilates surface plate velocities and shallow thermal structure of slabs into mantle flow models, we show that complete Izanagi plate subduction and margin-wide slab detachment induced a major change in sub-Pacific mantle flow, from dominantly southward before 60 Ma to north-northeastward after 50 Ma. Our results agree with onshore geology, mantle tomography, and the inferred motion of the Hawaiian hot spot and are consistent with a plate tectonic process driving the rapid plate-mantle reorganization in the Pacific hemisphere between 60 and 50 Ma. This reorganization is reflected in tectonic changes in the Pacific and surrounding ocean basins

    Exploring new drilling prospects in the southwest Pacific

    Get PDF
    A major International Ocean Discovery Program (IODP) workshop covering scientific ocean drilling in the southwest Pacific Ocean was held in Sydney, Australia, in late 2012. The workshop covered all fields of geoscience, and drilling targets in the area from the Equator to Antarctica. High-quality contributions and a positive and cooperative atmosphere ensured its success. The four science themes of the new IODP science plan were addressed. An additional resource-oriented theme considered possible co-investment opportunities involving IODP vessels. As a result of the workshop, existing proposals were revised and new ones written for the April 2013 deadline. Many of the proposals are broad and multidisciplinary in nature, hence broadening the scientific knowledge that can be produced by using the IODP infrastructure. This report briefly outlines the workshop and the related drilling plans

    Wastewater sludge ash in the production of a novel cold mix asphalt (CMA): durability, aging and toxicity characteristics

    Get PDF
    New Sustainable with no CO2 emission cold mix asphalt (CMA) for road and highways surfacing is successfully developed from wastewater sludge ash normally sent to landfills. The Paper reports; durability in terms of water sensitivity, aging and contamination levels of heavy metals of the new developed novel CMA containing upgraded fly and bottom ash secondary cementitious materials from United Utilities fly and bottom ashes. Road engineers currently restricted the use of conventional CMA containing conventional limestone fillers (LF) for use in walkways and light trafficked roads only, as these mixtures needs from 2 to 24 months for curing. Conventional CMA mixtures also have high voidage contents and thus low traffic bearing capacity. The durability of these mixes is low especially in the UK and European countries where the climate is predominantly wet and cold. In Germany and France, ordinary Portland cement (OPC) replaced the filler used in traditional CMA. Although this allows the new CMA to be used in roads for light and heavy trafficked loads. The materials are not environmentally friendly, as one tone of cement releases approximately one tone of CO2 emission during their manufacturing process. The results of the new developed CMA are satisfying the British and European codes of practices requirements. The new novel mixtures are also; highly cost-effective compared with the use of Hot Mix Asphalt (HMA), has no CO2 emission during mixing construction, and has no health and safety issues compared with the HMA manufacturing and application process

    High-sensitivity diamond magnetometer with nanoscale resolution

    Full text link
    We present a novel approach to the detection of weak magnetic fields that takes advantage of recently developed techniques for the coherent control of solid-state electron spin quantum bits. Specifically, we investigate a magnetic sensor based on Nitrogen-Vacancy centers in room-temperature diamond. We discuss two important applications of this technique: a nanoscale magnetometer that could potentially detect precession of single nuclear spins and an optical magnetic field imager combining spatial resolution ranging from micrometers to millimeters with a sensitivity approaching few femtotesla/Hz1/2^{1/2}.Comment: 29 pages, 4 figure
