Students' Academic Self Perception
Participation rates in higher education differ persistently between some groups in society. Using two British datasets we investigate whether this gap is rooted in studentsâ misperception of their own and otherâs ability, thereby increasing the expected costs to studying. Among high school pupils, we find that pupils with a more positive view of their academic abilities are more likely to expect to continue to higher education even after controlling for observable measures of ability and studentsâ characteristics. University students are also poor at estimating their own test-performance and over-estimate their predicted test score. However, females, white and working class students have less inflated view of themselves. Self-perception has limited impact on the expected probability of success and expected returns amongst these university students.Test performance, self-assessment, higher education participation, academic selfperception

Genomic Signatures of Historical Allopatry and Ecological Divergence in an Island Lizard
Geographical variation amongcontiguouspopulations is frequently attributed to ecological divergence or historical isolation followed by secondary contact.Distinguishing between these effects is key to studies of incipient speciation and could be revealed by different genomic signatures. We used RAD-seq analyses to examine morphologically divergent populations of the endemic lizard (Gallotia galloti) from the volcanic island of Tenerife. Previous analyses have suggested ecological and historical causes to explain the morphological diversity. Analyses of 276,483 single nucleotide polymorphisms (SNPs) from>20 Mbp of the genome revealed one genetically divergent population from Anaga, a region associated with divergent mtDNA lineages in other Tenerife endemics. This population also has a high number of private alleles, and its divergence can be explained by historical isolation. Bayesian outlier analyses identified a small proportion of SNPs as candidates for selection (0.04%) which were strongly differentiated between xeric andmesic habitat types. Individual testing for specific xericâmesic selection using an alternative approach also supported ecological divergence in a similarly small proportion of SNPs. The study indicates the roles of both historical isolation and ecological divergence in shaping genomic diversity in G. galloti.However, northâsouthmorphological divergence appears solely associated with the latter and likely involves a relatively small proportion of the genome
The HIP-HOP Flooring Study: Helping Injury Prevention in Hospitalised Older People:Pilot Cluster Randomised Controlled Trial of Flooring to Reduce Injuries from Falls in Elderly Care Units: Final Report
Comparing airborne algorithms for greenhouse gas flux measurements over the Alberta oil sands
To combat global warming, Canada has committed to reducing greenhouse gases to be (GHGs) 40 %â45 % below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. Airborne methods can provide regional and area source measurements with small error if ideal conditions for sampling are met. In this study, two airborne mass-balance box-flight algorithms were compared to assess the extent of their agreement and their performance under various conditions. The Scientific Aviationâs (SciAv) Gaussian algorithm and the Environment and Climate Change Canadaâs top-down emission rate retrieval algorithm (TERRA) were applied to data from five samples. Estimates were compared using standard procedures, by systematically testing other method fits, and by investigating the effects on the estimates when method assumptions were not met. Results indicate that in standard scenarios the SciAv and TERRA mass-balance box-flight methods produce similar estimates that agree (3%â25%) within algorithm uncertainties (4%â 34%). Implementing a sample-specific surface extrapolation procedure for the SciAv algorithm may improve emission estimation. Algorithms disagreed when non-ideal conditions occurred (i.e., under non-stationary atmospheric conditions). Overall, the results provide confidence in the box-flight methods and indicate that emissions estimates are not overly sensitive to the choice of algorithm but demonstrate that fundamental algorithm assumptions should be assessed for each flight. Using a different method, the Airborne Visible InfraRed Imaging Spectrometer â Next Generation (AVIRIS-NG) independently mapped individual plumes with emissions 5 times larger than the source SciAv sampled three days later. The range in estimates highlights the utility of increased sampling to get a more complete understanding of the temporal variability of emissions and to identify emission sources within facilities. In addition, hourly on-site activity data would provide insight to the observed temporal variability in emissions and make a comparison to reported emissions more straightforward
Action heritage: research, communities, social justice
Societies are unequal and unjust to varying degrees and heritage practitioners unavoidably work with, perpetuate and have the potential to change these inequalities. This article proposes a new framework for undertaking heritage research that can be applied widely and purposefully to achieve social justice, and which we refer to as action heritage. Our primary sources are semi-structured conversations we held with some of the participants in three heritage projects in South Yorkshire, UK: members of a hostel for homeless young people, a primary school, and a local history group. We examine âdisruptionsâ in the projects to understand the repositioning of the participants as researchers. The disruptions include introducing a scrapbook for personal stories in the homeless youth project and giving the school children opportunities to excavate alongside professional archaeologists. These disruptions reveal material and social inequalities through perceptible changes in how the projects were oriented and how the participants thought about the research. We draw on this empirical research and theorisations of social justice to develop a new framework for undertaking co-produced research. Action heritage is âundisciplinaryâ research that privileges process over outcomes, and which achieves parity of participation between academic and community-based researchers through sustained recognition and redistribution
Results from the GeoERA MUSE shallow geothermal project â UK Cardiff pilot area
Shallow geothermal energy systems deployment will play an important part in decarbonisation of heating and cooling of buildings. This trend will stimulate research into ground physical, thermal and hydraulic properties and impacts on urban aquifers and infrastructures. Moreover, subsurface heat extraction must be perceived as reliable, sustainable and equitable to create an environment for social acceptance and uptake of geothermal technologies. The EU H2020-funded GeoERA âMUSEâ project (2018-2021), involved 16 Geological Surveys, who shared methods and developed harmonised workflows for the evaluation of shallow geothermal resources in European urban areas (Götzl et al., EGC 2022). The project deployed and tested ground characterisation and geophysical monitoring techniques, monitored GSHP schemes, analysed the local market situation, produced fact sheets, made policy recommendations, and developed adaptive management strategies. The research included in-field monitoring studies in 14 urban pilot areas across Europe, including three UK urban pilot areas; Cardiff in south Wales, Glasgow in west Scotland and Colchester in east England. This paper summarises the result with a focus on the Cardiff area
Challenging the field: Bourdieu and men's health
©2014 Macmillan Publishers Ltd. This article considers how understandings of health promotion with men may be assisted by engagement with Bourdieu's theoretical work. The article outlines leading concepts within Bourdieu's work on 'field', 'habitus' and 'capital'; considers subsequent critical debates among gender, feminist and sociological theorists around structure and agency; and links these to discussions within men's health. A particular focus concerns structural disruption of, and movement of social actors between, 'fields' such as family, work and leisure settings. The article examines, through Bourdieu's critical legacy, whether such disruption establishes conditions for transformative reflexivity among men in relation to previously held dispositions (habitus), including those inflected by masculinities, that affect men's health practices. Recent work within Bourdieu's heritage potentially facilitates a re-framing of understandings of men's health practices. The article specifically explores masculine ambivalence within accounts of reflexivity, identities and practice, and considers how social and symbolic (masculine) capital are in play. Implications of Bourdieu's leading concepts for theorising settings-focused approaches to men's health promotion are exemplified with reference to a men's health project in a football stadium leisure setting. The article considers the benefits and challenges of applying gendered critical insights drawing on Bourdieu's work to men's health promotion, and discusses emerging theoretical dilemmas
The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe
The preponderance of matter over antimatter in the early Universe, the
dynamics of the supernova bursts that produced the heavy elements necessary for
life and whether protons eventually decay --- these mysteries at the forefront
of particle physics and astrophysics are key to understanding the early
evolution of our Universe, its current state and its eventual fate. The
Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed
plan for a world-class experiment dedicated to addressing these questions. LBNE
is conceived around three central components: (1) a new, high-intensity
neutrino source generated from a megawatt-class proton accelerator at Fermi
National Accelerator Laboratory, (2) a near neutrino detector just downstream
of the source, and (3) a massive liquid argon time-projection chamber deployed
as a far detector deep underground at the Sanford Underground Research
Facility. This facility, located at the site of the former Homestake Mine in
Lead, South Dakota, is approximately 1,300 km from the neutrino source at
Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino
charge-parity symmetry violation and mass ordering effects. This ambitious yet
cost-effective design incorporates scalability and flexibility and can
accommodate a variety of upgrades and contributions. With its exceptional
combination of experimental configuration, technical capabilities, and
potential for transformative discoveries, LBNE promises to be a vital facility
for the field of particle physics worldwide, providing physicists from around
the globe with opportunities to collaborate in a twenty to thirty year program
of exciting science. In this document we provide a comprehensive overview of
LBNE's scientific objectives, its place in the landscape of neutrino physics
worldwide, the technologies it will incorporate and the capabilities it will
possess.Comment: Major update of previous version. This is the reference document for
LBNE science program and current status. Chapters 1, 3, and 9 provide a
comprehensive overview of LBNE's scientific objectives, its place in the
landscape of neutrino physics worldwide, the technologies it will incorporate
and the capabilities it will possess. 288 pages, 116 figure
