    We have incorporated next-to-leading logarithmic corrections into the High Energy Jets (HEJ) formalism and parton-level Monte Carlo generator for WW plus inclusive dijet production. This has involved an analytic demonstration of factorisation for the relevant configurations, an extraction of the effective current and proof of its gauge invariance. We have thoroughly validated our numerical implementation and matching of the cross section to leading order accuracy. We have studied the impact of these corrections upon transverse momentum distributions and found a significant improvement in the description of data. We also present a new merging algorithm, inspired by the CKKW-L method, for combining high energy and soft-collinear logarithms. This has been implemented for HEJ+\textsc{Pythia}. Multiple parton interactions and hadronisation effects are also accounted for, allowing for an accurate description of jets shapes. We find good agreement with data for observables such as the average number of jets and gap fractions which are relevant for understanding the impact of jet vetoes

    In the context of design studies for future pppp colliders, we present a set of predictions for average soft-QCD event properties for pppp collisions at ECM=14E_\mathrm{CM} = 14, 2727, and 100100 TeV. The current default Monash 2013 tune of the PYTHIA 8.2 event generator is used as the baseline for the extrapolations, with uncertainties evaluated via variations of cross-section parametrisations, PDFs, MPI energy-scaling parameters, and colour-reconnection modelling, subject to current LHC constraints. The observables included in the study are total and inelastic cross sections, inelastic average energy and track densities per unit pseudorapidity (inside ∣η∣≤6|\eta|\le 6), average track p⊥p_\perp, and jet cross sections for 50- and 100-GeV anti-kTk_T jets with ΔR=0.4\Delta R=0.4, using aMC@NLO in conjunction with PYTHIA 8 for the latter.Comment: 25 pages, 10 figures, 9 tables; updated to version accepted for publicatio

    The Potential Role of Comics in Teaching Qualitative Research Methods

    This article argues that comics have a potentially positive role to play in supporting the teaching of qualitative research methods in higher education. It tells the story of the creation and use of a short pedagogical comic. We begin with a brief review of the literature around the use of comics in teaching. Then we offer two first-person accounts. Independent researcher Helen Kara narrates her creation of Conversation with a Purpose, designed as a resource to support the teaching of qualitative interviewing. It contains the story of a student’s first real-world interview, with some deliberately ambiguous aspects, and some discussion questions. Then Jenni Brooks, a senior lecturer in sociology at Sheffield Hallam University, outlines her use of the comic in teaching undergraduate sociology students. Each author offers a brief reflection on her experience. We conclude that the use of comics has the potential to bridge the gap between classroom and practice for inexperienced qualitative researchers, and we encourage further research in this area

    ABSTRACT AN INVESTIGATION OF TRADITIONAL PROFESSIONAL DEVELOPMENT VERSUS REFORM PROFESSIONAL DEVELOPMENT AND THE IMPLEMENTATION OF STRATEGIES, CURRICULUM AND CLASSROOM ENVIRONMENT BY PRE- KINDERGARTEN TEACHERS by HELEN OLIVER-BROOKS May 2013 Advisor: Dr. Marc Rosa Major: Curriculum and Instruction Degree: Doctor of Philosophy The purpose of this study is to investigate differences between traditional conventional professional development and high quality reflective professional development and curriculum implementation of classroom practices. This study examined the extent to which professional development activities were associated with increased levels of curriculum implementation. Differences in curriculum implementation, teacher knowledge, and changes to teaching practice based upon the type of professional development that teachers have experienced were a focus of this study. A sample of 132 prekindergarten teachers engaged in implementation of a newly adopted curriculum, High Scope, participated in the study. Professional development was provided for two consecutive academic years (2010-2011 and 2011-2012). Traditional professional development (lecture, large group, lower frequency, and no active participation) was provided during the first year. The second year, teachers participated in reform professional development programs (smaller groups, one location, consistent presenter, immediate on-going feedback/support, cohort/team approach, interaction, and a higher frequency of training sessions). Teachers completed a survey of the final day of the reform professional development session at the end of the 2012 school year. The findings were consistent with studies of significant professional development and the teachers\u27 conclusions about how effective specific types of training influenced their understanding and implementing of the curriculum. The findings further supported the significance of immediate feedback and consequently the on-going classroom, phone, text, email, and other means of support for promoting the High Scope curriculum implementation in the prekindergarten classroom

    A qualitative study of the views of patients with medically unexplained symptoms on The BodyMind Approach®: Employing embodied methods and arts practices for self-management

    Get PDF
    Funding Information: The study (2005-9) was funded by the East of England Development Agency and the University of Hertfordshire and data collected 2012–2016 were funded by the Department of Health QIPP program and East and North Herts, and Herts Valleys Clinical Commissioning Groups. Publisher Copyright: © Copyright © 2020 Payne and Brooks.The arts provide openings for symbolic expression by engaging the sensory experience in the body they become a source of insight through embodied cognition and emotion, enabling meaning-making, and acting as a catalyst for change. This synthesis of sensation and enactive, embodied expression through movement and the arts is capitalized on in The BodyMind Approach ® (TBMA). It is integral to this biopsychosocial, innovative, unique intervention for people suffering medically unexplained symptoms (MUS) applied in primary healthcare. The relevance of embodiment and arts practices in TBMA are discussed in relation to the views of participants in the pursuit of self-management. If widely employed TBMA could have an enormous impact, reach, and significance for patients and global health services. This original pre-clinical trial of qualitative research reports on the perceptions of participant patients with generic MUS, a world-wide issue usually treated by either psychological therapy or physiotherapy. TBMA is not a therapy but a health education program founded upon the concept of an integration of psychological elements with physiological, bodily, and sensory experiences. Thematic analysis of qualitative data sets from open-ended questions in semi-structured interviews and a written questionnaire post intervention is presented. Five aspects which appear to be key to learning self-management were derived from analyzing the data: (1) body with mind connections; (2) importance of facilitation; (3) potential benefits; (4) preparedness for change; (5) self-acceptance/compassion. This article advances the discourse on the nature of self-management for MUS through changing the mind-set and the relationship participants have with their bodily symptom/s through employing embodied methods and arts practices, challenging current, and solely verbal, psychological conceptual frameworks. Rigor lies in the method of data analysis using cross verification of credibility between reported findings and scrutiny by stakeholders. We conclude that facilitated TBMA groups employing embodied methods and arts practices can act as a method for developing the self-management of MUS and improving wellbeing.Peer reviewedFinal Published versio

    Clinical outcomes from The BodyMind Approachâ„¢ in the treatment of patients with medically unexplained symptoms in primary health care in England: practice-based evidence

    This is the accepted manuscript version of the following article: Helen Payne and Susan D. M. Brooks, ‘Clinical outcomes from The BodyMind Approach™ in the treatment of patients with medically unexplained symptoms in primary health care in England: Practice-based evidence’, The Arts in Psychotherapy, Vol 47: 55-65, February 2016, doi: http://dx.doi.org/10.1016/j.aip.2015.12.001. This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/.This article builds on Payne (2015) and reports on practice–based evidence arising out of the delivery of a new and innovative service using The BodyMind Approach™ (TBMA) for the treatment of patients with medically unexplained symptoms (MUS) in primary care in the National Health Service (NHS) in Hertfordshire, a county near London, England, in the UK. The analysis of data collected for three groups (N=16) over 18 months used standardised assessment tools and other relevant information at pre, post and at a six month follow up. The outcomes for patients in this small scale piece of practice based evidence indicated that there were reductions in symptom distress, anxiety and depression, increased overall wellbeing and improvement in activity levels. Patients developed self-management of their symptoms through understanding, acceptance and coping strategies. The increased knowledge, exchange of experiences together with understanding and acceptance from others promoted a sense of wellbeing. Thus, the programme was experienced to be a beneficial intervention. In addition to the clinical outcomes reported here there are other benefits for NHS England for example, savings on medication and referral costs and General Practitioner (GP) capacity enhanced. The clinical service is based on previous research conducted by Payne and Stott (2010). This article focusses solely on the analysis and interpretation of clinical outcomes from the practice-based evidence.

    Interleaved resonance decays and electroweak radiation in the Vincia parton shower

    Get PDF
    We propose a framework for high-energy interactions in which resonance decays and electroweak branching processes are interleaved with the QCD evolution in a single common sequence of decreasing resolution scales. The interleaved treatment of resonance decays allows for a new treatment of finite-width effects in parton showers. At scales above their offshellness (i.e., typically Q > γ ), resonances participate explicitly as incoming and outgoing states in branching processes, while they are effectively "integrated out" of the description at lower scales. We implement this formalism, together with a full set of antenna functions for branching processes involving electroweak (W=Z=H) bosons in the Vincia shower module in Pythia 8.3, and study some of the consequences
