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 selfâharm scars in the therapy room. Its form takes the shape of the author's personal meaningâmaking journey, beginning by exploring the construction of the therapist identity before going on to consider the wounded healer paradigm and the navigation of selfâdisclosure. 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 selfâharm scars, all therapists have a body which plays âa significant part of his or her unique contribution to therapyâ (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
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

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