Crossing the Boundary: a study of the nature and extent of racism in local league cricket
Since the start of the 1993/4 football season the 'Let's Kick Racism Out of Football’ has had some success in persuading clubs and players to recognise racism in the game and act to counter it. This summer, following our own research (Long et al, 1995) the Rugby Football League and the Commission for Racial Equality launched a 13-point Action Plan for professional clubs to adopt. Within cricket 'Hit Racism for Six' (HR46) was set-up last year to act as a pressure group to stimulate discussion about racism in cricket. Issues of race and racism in sport have recently attracted considerable media attention and stimulated popular debate. Emotion has run high over the articles by Robert Henderson (1995) and Roger Bannister (Connor 1995), the continuing confrontation between Raymond Illingworth and Devon Malcolm, the Botham/Lamb v Khan court case and the trouble on the terraces at Headingley during the summer of 1996. The balance attempted by programmes in the Radio 5 series on ‘Race around the UK’ represented one attempt to encourage a more considered approach, but throughout it has been clear that there is still a shortage of substantive research on race in sport. The Carnegie National Sports Development Centre conducted a study of black and ethnic minorities in cricket in Yorkshire that focused on issues of participation and sports development. Following the success of our rugby league project, Leeds City Council were keen for us to try to explore the more sensitive issues around race and racism. While the study of rugby league had been on the professional game this study of cricket was to be of local league cricket. Within the region this is how most people experience their cricket with some 1,300 teams affiliated to the Yorkshire Cricket Association. To establish views on race and racism we sought responses from: a) the secretaries of local league clubs b) Asian, black and white players in the leagues c) league umpire
Spherically Symmetric Solutions in Ghost-Free Massive Gravity
Recently, a class of theories of massive gravity has been shown to be
ghost-free. We study the spherically symmetric solutions in the bigravity
formulation of such theories. In general, the solutions admit both a Lorentz
invariant and a Lorentz breaking asymptotically flat behaviour and also fall in
two branches. In the first branch, all solutions can be found analitycally and
are Schwarzschild-like, with no modification as is found for other classes of
theories. In the second branch, exact solutions are hard to find, and relying
on perturbation theory, Yukawa-like modifications of the static potential are
found. The general structure of the solutions suggests that the bigravity
formulation of massive gravity is crucial and more than a tool.Comment: 15 pages. Some change in the reference
Pearson's random walk in the space of the CMB phases: evidence for parity asymmetry
The temperature fluctuations of the Cosmic Microwave Background (CMB) are
supposed to be distributed randomly in both magnitude and phase, following to
the simplest model of inflation. In this paper, we look at the odd and even
multipoles of the spherical harmonic decomposition of the CMB, and the
different characteristics of these, giving rise to a parity asymmetry. We
compare the even and odd multipoles in the CMB power spectrum, and also the
even and odd mean angles. We find for the multipoles of the power spectrum,
that there is power excess in odd multipoles, compared to even ones, meaning
that we have a parity asymmetry. Further, for the phases, we present a random
walk for the mean angles, and find a significant separation for even/odd mean
angles, especially so for galactic coordinates. This is further tested and
confirmed with a directional parity test, comparing the parity asymmetry in
galactic and ecliptic coordinates.Comment: Accepted for publication in Phys. Rev. D, 10 pages, 10 figures, 1

The Challenges of Sport Psychology Delivery in Elite and Professional Sport: Reflections From Experienced Sport Psychologists
The challenges encountered by sport psychologists operating within elite and professional sports teams have arguably been inadequately considered (Nesti, 2010). It has been suggested that this may be due to the inaccessibility of elite team environments (Eubank, Nesti, & Cruickshank, 2014; Nesti, 2010). The purpose of this research was to examine the chal- lenges facing practitioners who operate in elite environments and to illuminate how these were experienced. Qualitative interviews with six experienced applied sport psychologists were conducted and a narrative themed analysis undertaken. Four main themes emerged as most prevalent and meaningful: challenges to congruence, a broader role: managing multiple relationships, the influence of elite sport cultures, and surviving and thriving were presented in narrative form. Practitio- ners provided experiential insight into how specific challenges were understood and dealt with, and how they are able to provide an effective service while managing themselves and the demands of the environment
First Limits on Left-Right Symmetry Scale from LHC Data
We use the early Large Hadron Collider data to set the lower limit on the
scale of Left-Right symmetry, by searching for the right-handed charged gauge
boson via the final state with two leptons and two jets, for 33/pb
integrated luminosity and 7 TeV center-of-mass energy. In the absence of a
signal beyond the Standard Model background, we set the bound M_WR > 1.4 TeV at
95% C.L.. This result is obtained for a range of right-handed neutrino masses
of the order of few 100 GeV, assuming no accidental cancelation in right-handed
lepton mixings.Comment: 4 pages, added reference
Exploring athletic identity in elite-level English youth football: a cross-sectional approach.
This study is the first empirical investigation that has explored levels of athletic identity in elite-level English professional football. The importance of understanding athletes' psychological well-being within professional sport has been well documented. This is especially important within the professional football industry, given the high attrition rate (Anderson, G., & Miller, R. M. (2011). The academy system in English professional football: Business value or following the herd? University of Liverpool, Management School Research Paper Series. Retrieved from http://www.liv.ac.uk/managementschool/research/working%20papers/wp201143.pdf ) and distinct occupational practices (Roderick, M. (2006). The work of professional football. A labour of love? London: Routledge). A total of 168 elite youth footballers from the English professional football leagues completed the Athletic Identity Measurement Scale (AIMS). Multilevel modelling was used to examine the effect of playing level, living arrangements and year of apprentice on the total AIMS score and its subscales (i.e., social identity, exclusivity and negative affectivity). Football club explained 30% of the variance in exclusivity among players (P = .022). Mean social identity was significantly higher for those players in the first year of their apprenticeship compared to the second year (P = .025). All other effects were not statistically significant (P > .05). The novel and unique findings have practical implications in the design and implementation of career support strategies with respect to social identity. This may facilitate the maintenance of motivation over a 2-year apprenticeship and positively impact on performance levels within the professional football environment
Spontaneous Lorentz Breaking and Massive Gravity
We study a theory where the presence of an extra spin-two field coupled to
gravity gives rise to a phase with spontaneously broken Lorentz symmetry. In
this phase gravity is massive, and the Weak Equivalence Principle is respected.
The newtonian potentials are in general modified, but we identify an
non-perturbative symmetry that protects them. The gravitational waves sector
has a rich phenomenology: sources emit a combination of massless and massive
gravitons that propagate with distinct velocities and also oscillate. Since
their velocities differ from the speed of light, the time of flight difference
between gravitons and photons from a common source could be measured.Comment: 4 page
Type II Seesaw at LHC: the Roadmap
In this Letter we revisit the type-II seesaw mechanism based on the addition
of a weak triplet scalar to the standard model. We perform a comprehensive
study of its phenomenology at the LHC energies, complete with the electroweak
precision constraints. We pay special attention to the doubly-charged
component, object of collider searches for a long time, and show how the
experimental bound on its mass depends crucially on the particle spectrum of
the theory. Our study can be used as a roadmap for future complete LHC studies.Comment: 5 pages, 4 figures; added discussion on collider signatures including
the impact on SM Higgs searches and accommodating Higgs to two photon rate,
and references; latest version agrees with the published on
