Community Sport Coaching and Impression Management
This chapter positions community sport coaching work as a social, interactive performance. It begins by introducing the concept of dramaturgy and Erving Goffman’s ground-breaking work addressing ‘the presentation of the self in everyday life. This background information is then followed by an exposition of some of Goffman’s central dramaturgical concepts and the ways in which they connect with, and could be used to inform, everyday community sport coaching practice. Here, Callum, the last author, provides detailed examples of how he has utilised these dramaturgical concepts to inform the ways in which he performs his community sport coaching role. Finally, the conclusion summarises the central arguments and issues raised in this chapter and provides some critical questions to stimulate your reflection on the dramaturgical dimensions of everyday practice
School Bullying: a Social Justice Issue? How Restorative Approaches May Prevent Future Violence
This article by Callum Jones discusses how restorative approaches by schools could be used to prevent future harm. The author explores how bullying is experienced, how it could be linked to future violent crime, and how school bullying prevention is a social justice issue

Constraining the GENIE model of neutrino-induced single pion production using reanalyzed bubble chamber data
The longstanding discrepancy between bubble chamber measurements of -induced single pion production channels has led to large uncertainties in pion production cross section parameters for many years. We extend the reanalysis of pion production data in deuterium bubble chambers where this discrepancy is solved (Wilkinson et al., PRD 90, 112017 2014) to include the and channels, and use the resulting data to fit the parameters of the GENIE pion production model. We find a set of parameters that can describe the bubble chamber data better than the GENIE default parameters, and provide updated central values and reduced uncertainties for use in neutrino oscillation and cross section analyses which use the GENIE model. We find that GENIE’s non-resonant background prediction has to be significantly reduced to fit the data, which may help to explain the recent discrepancies between simulation and data observed by the MINERA coherent pion and NOA oscillation analyses
Becoming Atheist: Humanism and the Secular West
The western world is becoming atheist. In the space of three generations, churchgoing and religious belief have become alien to millions. We are in the midst of one of humankind's great cultural changes. How has this happened? Becoming Atheist offers the most thorough analysis of this phenomenon to date, exploring through their own words how people have come to live their lives as if there is no God. It tells the stories of those who have come to secular lives in Britain, western Europe, the United States and Canada, mostly from Christian and Jewish backgrounds. Based on interviews with over 80 people born in 18 countries, Callum Brown shows that a long-latent humanism has been roused in the post-1945 secularising west. Focusing on the gender, ethnic and childhood dimensions of atheists from the United Kingdom, the USA, Canada and Europe, the author looks at how the religious condition of the western world changed during the 20th and 21st centuries. By listening to individuals' life stories, this book moves away from mere statistical or broad cultural analysis. Making extensive use of frank, humorous and sometimes harrowing personal testimony, Becoming Atheist exposes the people's role in renegotiating their own identities and fashioning a secular and humanist culture for the western world
Simultaneous measurement of the muon neutrino charged-current cross section on oxygen and carbon without pions in the final state at T2K
This paper reports the first simultaneous measurement of the double differential muon neutrino charged-current cross section on oxygen and carbon without pions in the final state as a function of the outgoing muon kinematics, made at the ND280 off-axis near detector of the T2K experiment. The ratio of the oxygen and carbon cross sections is also provided to help validate various models’ ability to extrapolate between carbon and oxygen nuclear targets, as is required in T2K oscillation analyses. The data are taken using a neutrino beam with an energy spectrum peaked at 0.6 GeV. The extracted measurement is compared with the prediction from different Monte Carlo neutrino-nucleus interaction event generators, showing particular model separation for very forward-going muons. Overall, of the models tested, the result is best described using local Fermi gas descriptions of the nuclear ground state with RPA suppression
Measurement of meson resonance production in π−+ C interactions at SPS energies
We present measurements of p⁰, ω and K*⁰ spectra in π−+C production interactions at 158 GeV/c and p⁰ spectra at 350 GeV/c using the NA61/SHINE spectrometer at the CERN SPS. Spectra are presented as a function of the Feynman's variable XF in the range 0 < XF < 1 and for 158 GeV/c and 350 GeV/c respectively. Furthermore, we show comparisons with previous measurements and predictions of several hadronic interaction models. These measurements are essential for a better understanding of hadronic shower development and for improving the modeling of cosmic ray air showers
Constraining neutrino interaction uncertainties for oscillation experiments
Neutrinos rarely interact, but sometimes they do. How much? And does it matter? Charged-Current Quasi-Elastic (CCQE) neutrino-nucleus interactions are the main signal channel for T2K and other currently running neutrino oscillation experiments, but in recent years, with a number of experimental results, it has become clear that these interactions are not as well understood at few-GeV neutrino energies as was previously thought. This thesis focuses on the impact that this uncertainty will have on neutrino oscillation measurements. Published CCQE and the closely related Neutral-Current Elastic (NCEL) cross section results from the MiniBooNE experiment are used to fit a 3+1 sterile neutrino model, and the uncertainty over fundamental parameters in the cross section model used is shown to badly bias the results. Conservative sterile neutrino limits which treat the cross section uncertainty correctly are used, and a general note of caution is sounded over sterile neutrino results which make tacit and unfounded assumptions about the neutrino cross section model. New theoretical models of CCQE scattering which try to explain the experimental situation have become available, some of which have been implemented into NEUT, T2K's primary interaction generator. Two candidate models are used in a fit to all published CCQE data on nuclear targets to select a default model and constrain the parameters of that model in order to increase the sensitivity of T2K oscillation analyses. This CCQE parametrisation will be used for T2K oscillation analyses from the summer of 2015 onwards. The fit framework developed for this work has been integrated into the T2K oscillation analysis framework for future iterations. Additionally, the implementation of one such model, the Effective Spectral Function is described and compared with the available neutrino-nucleus scattering data
