Effectiveness and cost-effectiveness of a novel, group self-management course for adults with chronic musculoskeletal pain: study protocol for a multicentre, randomised controlled trial (COPERS)
No full textIntroduction: Chronic musculoskeletal pain is a common condition that often responds poorly to treatment. Self-management courses have been advocated as a non-drug pain management technique, although evidence for their effectiveness is equivocal. We designed and piloted a self-management course based on evidence for effectiveness for specific course components and characteristics. Methods/analysis: COPERS (coping with persistent pain, effectiveness research into self-management) is a pragmatic randomised controlled trial testing the effectiveness and cost-effectiveness of an intensive, group, cognitive behavioural-based, theoretically informed and manualised self-management course for chronic pain patients against a control of best usual care: a pain education booklet and a relaxation CD. The course lasts for 15 h, spread over 3 days, with a –2 h follow-up session 2 weeks later. We aim to recruit 685 participants with chronic musculoskeletal pain from primary, intermediate and secondary care services in two UK regions. The study is powered to show a standardised mean difference of 0.3 in the primary outcome, pain-related disability. Secondary outcomes include generic health-related quality of life, healthcare utilisation, pain self-efficacy, coping, depression, anxiety and social engagement. Outcomes are measured at 6 and 12 months postrandomisation. Pain self-efficacy is measured at 3 months to assess whether change mediates clinical effect. Ethics/dissemination: Ethics approval was given by Cambridgeshire Ethics 11/EE/046. This trial will provide robust data on the effectiveness and cost-effectiveness of an evidence-based, group self-management programme for chronic musculoskeletal pain. The published outcomes will help to inform future policy and practice around such self-management courses, both nationally and internationally. Trial registration: ISRCTN24426731
Development of a new Soft Muon Tagger for the Identification of b quarks, applied to a Top Quark Pair Production Cross Section Measurement, using the ATLAS Detector at CERN.
No full textThis thesis presents a study of a method for identifying b-jets by searching for “soft” muons produced within them. This method, a so-called Soft Muon Tagger, uses the quality of the match (Χ2match) between tracks left in the inner detector and the muon systems within the ATLAS detector to discriminate between muons within hadronic jets produced by the decay of b quarks, and those within light flavour jets.
The complete characteristics of the tagger are investigated in a detailed study on simulated data. The scale factors between the efficiency of the tagger in simulated and collision data, dependent on the kinematics of the tagged muon, are found using J/Ψ decays. These are used in a measurement of the top quark pair production cross section in collision data.
The measurement is performed on data taken during the 2011 run of the LHC, specifically in the lepton+jets top-antitop quark decay channel. A summary of this measurement is presented, and is found to be compatible with theoretical predictions for the cross section at a centre of mass energy of √s = 7 TeV, and with published ATLAS and CMS measurements using b-tagging in the lepton+jets channel. The measured cross section is:
σtt ̄ = 165 ± 2(stat.) ± 17(syst.) ± 3(lumi.) pb
The Χ2match-based soft muon tagger contributes a small b-tagging systematic uncertainty to the cross section measurement compared to measurements performed using lifetime based b-taggers, and has a good signal to background ratio
Don’t mention Europe: a study of the Europeanisation of party organisation in the British Labour Party, the French Socialist Party and the German Social Democratic Party.
No full textThis thesis examines how the British Labour Party, the French Socialist Party (PS) and the German Social Democratic Party (SPD) have ‘Europeanised’ their organisations in three different arenas: (1) in the electorate and party system; (2) in central government and parliament; and (3) in their internal procedures and activities. ‘Europeanisation’ is defined as ‘a shorthand term for a complex process whereby national actors (in this case, parties) adapt to, and also seek to shape, the trajectory of European integration in general, and EU policies and processes in particular’ (Bomberg: 2002, 32). The underlying argument is that social democratic parties have to respond to challenges created by the European Single Market, which demands the reduction of state subsidies, and by the Economic and Monetary Union (EMU), which sets limits to public spending. Social democratic parties are expected to react to these challenges by Europeanising their organisations.
This thesis draws on the academic literature, party documents and contemporary newspaper articles, together with insights gained from 70 semi-structured interviews with EU experts at the European and national levels.
The central claim is that Labour, the PS and SPD have not become as Europeanised as might have been supposed for three ostensibly pro-European parties. Whilst successive party leaderships have paid lip service to the increasing importance of European integration, their party organisations have barely been involved in the formulation of European policy. The findings have serious implications for the three parties and domestic politics in Britain, France and Germany, since the memberships lack the enthusiasm and expertise to lead well-informed, critical, Europeanised debates and election campaigns
Curating Science in an Age of Empire: Kew's Museum of Economic Botany
No full textThis thesis considers the history and significance of the Museum of Economic Botany at the Royal Botanic Gardens, Kew, focussing especially on the period from its opening in 1847 to the eve of the First World War. Looking specifically at the Museum’s collection of wood specimens and artefacts, it seeks to understand the nature of economic botany during this period, and to evaluate the contribution made to the field by the Kew Museum. Through examination of the Museum’s practices, networks, spaces, and objects, it sets out to address the question: how do museums produce scientific knowledge? Part One sets the context. Chapter One provides a brief historical account of nineteenth-century economic botany and the Museum. Chapter Two offers a critical overview of literatures on Kew and economic botany; on the role of place in the production, circulation, and reception of scientific knowledge; and on the role of the public museum in Victorian science and culture. It also outlines the conceptual framework of the thesis. Chapter Three presents an account of the methodology and sources. Part Two highlights museum practices. Chapters Four to Six are devoted respectively to the practices of ‘exhibition’ (the spatialities, rhetorics, and rationalities of display); ‘instruction’ (the educational uses of museum objects); and ‘supply’ (the circulation of objects). Part Three turns to specific objects and their biographies. Chapters Seven and Eight trace respectively the production, circulation and reception of a totem pole from British Columbia and a timber trophy from Tasmania, to demonstrate how objects acquire diverse meanings in diverse contexts, and how they are used to impart meaning to particular sites. In conclusion, Chapter Nine reflects on the cumulative findings of the thesis and on its potential outcomes, and it looks beyond the thesis to recommend areas for future research and practice
Superconducting phase coherent electron transport in nano-engineered ferromagnetic vortices
No full textThis thesis presents an experimental study of the superconducting proximity effect in sub-micrometer sized ferromagnetic discs. Such discs belong to a class of mesoscopic ferromagnets intermediate between microscopic magnets with dimensions below about 10nm that behave as single giant spins and macroscopic structures that are larger than approximately 1 micrometer where domains are formed to minimise stray fields. The magnetic structure of mesoscopic magnets is strongly dependent on their geometric shape, allowing for purposeful engineering of magnetic structures using modern lithographic techniques. The ground magnetic state of mesoscopic ferromagnetic discs is the magnetic vortex where unusual time-asymmetric triplet superconductivity is predicted to exist and survive up to the non-magnetic coherence length, that is orders in magnitude larger than the ferromagnetic singlet coherence length. Magnetic Force Microscopy (MFM) was used to directly study the magnetic structure of the discs. To detect the proximity effect in the vortices, Andreev interferometers were used with normal parts replaced with mesoscopic ferromagnetic discs in the magnetic vortex state. The samples were fabricated using electron-beam lithography and a modified shadow evaporation technique developed within this project, allowing the whole structure to be made with highly precise alignment, without breaking vacuum and avoiding redundant ferromagnetic elements disturbing the magnetic vortices. Observations were made of superconducting phase periodic oscillations in the conductance of the Andreev interferometers. Such oscillations provide unambiguous evidence of phase coherent electron transport through the ferromagnetic vortex. Finally, further experiments are discussed that would provide a more detailed understanding of the long range proximity effect in SFS junctions
