University College London: Library DDA works PPG15 justification. Conservation strategy report.

Introduction: This report has been prepared for the Estates and Facilities Division of University College London (UCL). UCL needs to make alterations to the Wilkins building to improve access to the library (on its upper floors) by the end of the year in order to comply with the terms of the Disability Discrimination Act (DDA). In December 2003 Alan Baxter & Associates produced draft Management Guidelines for UCL which identified what is significant about the UCL buildings and to help streamline the process of gaining future listed building consents. This report is based on these Management Guidelines but includes information from the recent opening-up works. The Wilkins Building is Grade I listed. The new access proposals involve removing a staircase, one of which was inserted by TL Donaldson in 1849-51, and installing a lift (along with a new staircase) to provide access for the mobility impaired to the library. This report has been written to accompany an application for listed building consent, and to demonstrate that the alterations are required by the DDA, and are justifiable in terms of the criteria set out in PPG15. Although the proposed works affect only one part of the building, it is important to see them in the wider context of the building. This document begins by outlining the history of the Wilkins building as a whole, from its construction in 1827-9, through various modifications (notably by Donaldson), its reconstruction and restoration by A E Richardson following war damage, to its present day form (Sections 2 and 3). Section 4 also looks at the building as a whole, defining what elements of it contribute most particularly to the ‘outstanding’ architectural and historic importance given by its Grade I listing. These wider sections allow the current proposals to be assessed both for their impact on and the access benefits that they will bring to the building as a whole. Section 5 therefore focuses on the proposals to provide Disability Access to the library, describing and justifying them according to the criteria of PPG15, showing how they achieve an acceptable balance between the legitimate access requirements of those with disabilities and the special architectural and historic importance of the building

Hidden talents: examples of transition of careers guidance from local authorities to schools

This Local Government Association commissioned report helps collate case study examples of local authorities supporting schools in their enhanced role to provide independent and impartial careers guidance to young people. Eight LAs were selected by the LGA and NFER carried out telephone interviews with the key strategic lead on the transition of careers guidance from local authorities to schools. LAs nominated a school in their authority and NFER carried out telephone interviews with senior leaders and careers coordinators in seven schools. Key findings LAs are supporting schools to meet their new careers guidance duty firstly by encouraging the continued participation of young people in learning, tracking young people’s destinations, and identifying those with no clear pathways. Secondly, by providing direct support to schools, for example updates on policy matters and training on commissioning independent external careers guidance. Thirdly, LAs are supporting schools with the commissioning of careers guidance services from external providers. The schools in this study report that what has helped them to feel well prepared to take on their new statutory duty is: being well informed and supported by the LA and local partnerships; embracing the new legislation and carrying out their own preparation for the transition; having a well-qualified careers coordinator on their staff: and building on their current careers guidance systems. Schools are collaborating with a variety of different organisations to provide careers guidance. However, on the whole, schools indicated that they do not work with other schools to commission careers guidance provision because their priority is to procure careers guidance that is designed to meet the needs of their own students

Languages at key stage 4 2009-2011 : evaluation of the impact of Languages Review recommendations : baseline findings from the first year of the evaluation

• Heads of language departments consider good teaching and support to be central to encouraging language uptake at KS4, and constraints of the options system to be the main barrier. Many schools are reported to have received excellent support for languages in 2008/09 in terms of staffing, training and resources. • Some schools report a positive impact of the Languages Review recommendations but there is a low level of awareness of the Review in the majority of schools. • 19 per cent of schools set a benchmark for languages uptake in 2009/10 (at an average level of 64 per cent) but 62 per cent of schools had actual levels of uptake lower than 50 per cent. In schools where languages are optional (69 per cent of schools), 80 per cent had levels of uptake below 50 per cent

'If they are going to University, they are gonna need a language GCSE’: co-constructing the social divide in language learning in England

Despite increasing evidence of the UK language learning crisis, and the social divide between those opting for language study, or not, we know little about the language policies of individual schools might contribute to these phenomena. Little evidence exists on schools’ stakeholders’ views (senior management, language teachers, students) on the purposes for language study, and the relation of such views to language policies, in specific schools. This article reports on interviews and focus groups undertaken in four schools in the north of England, an area with low uptake of language learning beyond the compulsory age. In each school, focus groups with students (aged 13/14), and interviews with language teachers and senior management, were undertaken. Thematic analysis and corpus linguistics analyses were undertaken, using NVivo. Results reveal that students from all school types, including in areas of relative deprivation, rate and value languages. School management, however, may articulate a wide range of possible rationales for languages, but tend to devise and justify their language policy with reference to performance-driven pressures, academic and social background of their schools’ intake, and purported professional aspirations of their students. In this manner, language learning opportunities are shaped by social and academic school characteristics, rather than student preferences, contributing to the social divide in language learning in the UK

Search for neutral long-lived particles in pp collisions at √s = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter

A search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb−1 of proton-proton collision data collected by the ATLAS detector at the LHC in 2015–2018 at a centre-of-mass energy of 13 TeV. Dedicated techniques were developed for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are defined for different LLP kinematic regimes. The observed numbers of events are consistent with the expected background, and limits for several benchmark signals are determined. For a SM Higgs boson with a mass of 125 GeV, branching ratios above 10% are excluded at 95% confidence level for values of c times LLP mean proper lifetime in the range between 20 mm and 10 m depending on the model. Upper limits are also set on the cross-section times branching ratio for scalars with a mass of 60 GeV and for masses between 200 GeV and 1 TeV. [Figure not available: see fulltext.

Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector

This paper presents the measurement of fducial and diferential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity diference. The measured fducial cross sections for electroweak and inclusive W±W±jj production are 2.92 ± 0.22 (stat.) ± 0.19 (syst.)fb and 3.38±0.22 (stat.)±0.19 (syst.)fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95% confdence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons H±± that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an H±± mass near 450 GeV, with a global signifcance of 2.5 standard deviations

Search for pair production of squarks or gluinos decaying via sleptons or weak bosons in final states with two same-sign or three leptons with the ATLAS detector

A search for pair production of squarks or gluinos decaying via sleptons or weak bosons is reported. The search targets a final state with exactly two leptons with same-sign electric charge or at least three leptons without any charge requirement. The analysed data set corresponds to an integrated luminosity of 139 fb−1 of proton-proton collisions collected at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Multiple signal regions are defined, targeting several SUSY simplified models yielding the desired final states. A single control region is used to constrain the normalisation of the WZ + jets background. No significant excess of events over the Standard Model expectation is observed. The results are interpreted in the context of several supersymmetric models featuring R-parity conservation or R-parity violation, yielding exclusion limits surpassing those from previous searches. In models considering gluino (squark) pair production, gluino (squark) masses up to 2.2 (1.7) TeV are excluded at 95% confidence level

Studies of new Higgs boson interactions through nonresonant HH production in the b¯bγγ fnal state in pp collisions at √s = 13 TeV with the ATLAS detector

A search for nonresonant Higgs boson pair production in the b ¯bγγ fnal state is performed using 140 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. This analysis supersedes and expands upon the previous nonresonant ATLAS results in this fnal state based on the same data sample. The analysis strategy is optimised to probe anomalous values not only of the Higgs (H) boson self-coupling modifer κλ but also of the quartic HHV V (V = W, Z) coupling modifer κ2V . No signifcant excess above the expected background from Standard Model processes is observed. An observed upper limit µHH < 4.0 is set at 95% confdence level on the Higgs boson pair production cross-section normalised to its Standard Model prediction. The 95% confdence intervals for the coupling modifers are −1.4 < κλ < 6.9 and −0.5 < κ2V < 2.7, assuming all other Higgs boson couplings except the one under study are fxed to the Standard Model predictions. The results are interpreted in the Standard Model efective feld theory and Higgs efective feld theory frameworks in terms of constraints on the couplings of anomalous Higgs boson (self-)interactions

Comparison of inclusive and photon-tagged jet suppression in 5.02 TeV Pb+Pb collisions with ATLAS

Parton energy loss in the quark–gluon plasma (QGP) is studied with a measurement of photon-tagged jet production in 1.7 nb−1 of Pb+Pb data and 260 pb−1 of pp data, both at sNN=5.02 TeV, with the ATLAS detector. The process pp →γ+jet+X and its analogue in Pb+Pb collisions is measured in events containing an isolated photon with transverse momentum (pT) above 50 GeV and reported as a function of jet pT. This selection results in a sample of jets with a steeply falling pT distribution that are mostly initiated by the showering of quarks. The pp and Pb+Pb measurements are used to report the nuclear modification factor, RAA, and the fractional energy loss, Sloss, for photon-tagged jets. In addition, the results are compared with the analogous ones for inclusive jets, which have a significantly smaller quark-initiated fraction. The RAA and Sloss values are found to be significantly different between those for photon-tagged jets and inclusive jets, demonstrating that energy loss in the QGP is sensitive to the colour-charge of the initiating parton. The results are also compared with a variety of theoretical models of colour-charge-dependent energy loss

Model-independent search for the presence of new physics in events including H → γγ with s \sqrt{s} = 13 TeV pp data recorded by the ATLAS detector at the LHC

Abstract A model-independent search for new physics leading to final states containing a Higgs boson, with a mass of 125.09 GeV, decaying to a pair of photons is performed with 139 fb−1 of s $$\sqrt{s}$$ = 13 TeV pp collision data recorded by the ATLAS detector at the Large Hadron Collider at CERN. This search examines 22 final states categorized by the objects that are produced in association with the Higgs boson. These objects include isolated electrons or muons, hadronically decaying τ-leptons, additional photons, missing transverse momentum, and hadronic jets, as well as jets that are tagged as containing a b-hadron. No significant excesses above Standard Model expectations are observed and limits on the production cross section at 95% confidence level are set. Detector efficiencies are reported for all 22 signal regions, which can be used to convert detector-level cross-section limits reported in this paper to particle-level cross-section constraints
