    Journeying to visibility:an autoethnography of self-harm scars in the therapy room

    This autoethnography explores the experience of a therapist negotiating the visibility of their self‐harm scars in the therapy room. Its form takes the shape of the author's personal meaning‐making journey, beginning by exploring the construction of the therapist identity before going on to consider the wounded healer paradigm and the navigation of self‐disclosure. A thread throughout is finding ways to resist fear and shame as both a researcher and counsellor. The author concludes by recounting fragments of sessions from the first client she worked with while having her scars visible. While not every therapist will have self‐harm scars, all therapists have a body which plays “a significant part of his or her unique contribution to therapy” (Burka, 2013, p. 257). This paper is, therefore, potentially valuable to any therapist, at any stage of development, who seeks to reflect on the role of the body and use of the self

    Alpha_s: from DIS to LEP

    Full text link
    The strong coupling alpha_s is a fundamental parameter of the Standard Model. In comparison to parameters like alpha_em and M_Z it is relatively poorly known. However the precision of alpha_s measurements has improved dramatically in recent years. More than twenty different types of process, from lattice QCD studies to the highest energy colliders, can be used to measure alpha_s accurately. The most precise determinations now quote uncertainties in alpha_s(M_Z) of less than 5%. There is also a remarkable consistency between the various measurements. The present review provides an update on alpha_s measurements from the past year.Comment: 12 pages LaTeX and 4 encapsulated postscript figures, using epsfig and (modified) l-school macros.

    Personal notions of time travel:reflections on love, loss, and growth through autoethnography

    Get PDF
    Using the concept of time travel as a contextual and narrative tool, the author explores themes of love, loss and growth after trauma. Reflections relate primarily to the experience of conducting the qualitative research method of autoethnography. Opening with consideration of existing work (Yoga and Loss: An Autoethnographical Exploration of Grief, Mind, and Body), discussion moves on to academic thought on mental time travel, and personal transformation, culminating in the construction of a new memory combining past, present, and future

    The point of maximum curvature as a marker for physiological time series

    Full text link
    We present a geometric analysis of the model of Stirling. In particular we analyze the curvature of a heart rate time series in response to a step like increment in the exercise intensity. We present solutions for the point of maximum curvature which can be used as a marker of physiological interest. This marker defines the point after which the heart rate no longer continues to rapidly rise and instead follows either a steady state or slow rise. These methods are then applied to find analytic solutions for a mono exponential model which is commonly used in the literature to model the response to a moderate exercise intensity. Numerical solutions are then found for the full model and parameter values presented in Stirling

    On the Resummation of Subleading Logarithms in the Transverse Momentum Distribution of Vector Bosons Produced at Hadron Colliders

    Full text link
    The perturbation series for electroweak vector boson production at small transverse momentum is dominated by large double logarithms at each order in perturbation theory. An accurate theoretical prediction therefore requires a resummation of these logarithms. This can be performed either directly in transverse momentum space or in impact parameter (Fourier transform) space. While both approaches resum the same leading double logarithms, the subleading logarithms are, in general, treated differently. We comment on two recent approaches to this problem, emphasising the particular subleading logarithms resummed in each case and the numerical differences in the cross sections which result.Comment: 13 (Latex) pages, including 5 embedded figures, uses epsfig.st

    Electroweak gauge boson polarisation at the LHC

    Full text link
    We study the polarisation of gauge bosons produced at the LHC. Polarisation effects for W bosons manifest themselves in the angular distributions of the lepton and in the distributions of lepton transverse momentum and missing transverse energy. The distributions also depend on the selection cuts, with kinematic effects competing with polarisation effects. The polarisation is discussed for a range of different processes producing W bosons: W+jets, W from top (single and pair) production, W pair production and W production in association with a Z or Higgs boson. The relative contributions of the different polarisation states varies from process to process, reflecting the dynamics of the underlying hard-scattering process. We also present results for the polarisation of the Z boson produced in association with QCD jets at the LHC, and comment on the differences between W and Z production.Comment: 27 pages, 25 figure
