    The paper addresses the implications of using the process of systematic review in the many areas of leisure where there is a dearth of material that would be admitted into conventional Cochrane Reviews. This raises important questions about what constitutes legitimate knowledge, questions that are of critical import not just to leisure scholars, but to the formulation of policy. The search for certainty in an area that lacks conceptual consensus results in an epistemological imperialism that takes a geocentric form. While clearly, there is a need for good research design whatever the style of research, we contend that the wholesale rejection of insightful research is profligate and foolhardy. A mechanism has to be found to capitalise on good quality research of whatever form. In that search, we draw upon our experience of conducting a review of the material available on participation in sport and physical recreation by people from Black and minority ethnic groups. The paper concludes with a proposal for a more productive review process that makes better use of the full panoply of good quality research available. © 2012 © 2012 Taylor & Francis

    Managing and monitoring equality and diversity in UK sport: An evaluation of the sporting equals Racial Equality Standard and its impact on organizational change

    Get PDF
    Despite greater attention to racial equality in sport in recent years, the progress of national sports organizations toward creating equality of outcomes has been limited in the United Kingdom. The collaboration of the national sports agencies, equity organizations and national sports organizations (including national governing bodies of sport) has focused on Equality Standards. The authors revisit an earlier impact study of the Racial Equality Standard in sport and supplement it with another round of interview material to assess changing strategies to manage diversity in British sport. In particular, it tracks the impact on organizational commitment to diversity through the period of the establishment of the Racial Equality Standard and its replacement by an Equality Standard that deals with other diversity issues alongside race and ethnicity. As a result, the authors question whether the new, generic Equality Standard is capable of addressing racial diversity and promoting equality of outcomes. © 2006 Sage Publications

    Talk the talk, walk the walk: Defining Critical Race Theory in research

    Get PDF
    Over the last decade there has been a noticeable growth in published works citing Critical Race Theory (CRT). This has led to a growth in interest in the UK of practical research projects utilising CRT as their framework. It is clear that research on 'race' is an emerging topic of study. What is less visible is a debate on how CRT is positioned in relation to methodic practice, substantive theory and epistemological underpinnings. The efficacy of categories of data gathering tools, both traditional and non-traditional is a discussion point here to explore the complexities underpinning decisions to advocate a CRT framework. Notwithstanding intersectional issues, a CRT methodology is recognisable by how philosophical, political and ethical questions are established and maintained in relation to racialised problematics. This paper examines these tensions in establishing CRT methodologies and explores some of the essential criteria for researchers to consider in utilising a CRT framework. © 2012 Copyright Taylor and Francis Group, LLC

    Oscillator strengths with pseudopotentials

    The time-dependent local-density approximation (TDLDA) is shown to remain accurate in describing the atomic response of IB elements under the additional approximation of using pseudopotentials to treat the effects of core electrons. This extends the work of Zangwill and Soven who showed the utility of the all-electron TDLDA in the atomic response problem.Comment: 13 pages including 3 Postscript figure

    Unusual features in the nonlinear microwave surface impedance of Y-Ba-Cu-O thin films

    Full text link
    Striking features have been found in the nonlinear microwave (8 GHz) surface impedance Zs=Rs+jXsZ_s=R_s + jX_s of high-quality YBaCuO thin films with comparable low power characteristics [Rres3560μΩR_{res}\sim 35--60 \mu\Omega and λL(15K)130260nm\lambda_L(15 K)\sim 130--260 nm]. The surface resistance RsR_s is found to increase, decrease, or remain independent of the microwave field HrfH_{rf} (up to 60 mT) at different temperatures and for different samples. However, the surface reactance XsX_s always follows the same functional form. Mechanisms which may be responsible for the observed variations in RsR_s and XsX_s are briefly discussed.Comment: 4 pages, 4 figure

    Donor ionization in size controlled silicon nanocrystals: The transition from defect passivation to free electron generation

    Get PDF
    We studied the photoluminescence spectra of silicon and phosphorus co-implanted silica thin films on (100) silicon substrates as a function of isothermal annealing time. The rapid phase segregation, formation, and growth dynamics of intrinsic silicon nanocrystals are observed, in the first 600 s of rapid thermal processing, using dark field mode X-TEM. For short annealing times, when the nanocrystal size distribution exhibits a relatively small mean diameter, formation in the presence of phosphorus yields an increase in the luminescence intensity and a blue shift in the emission peak compared with intrinsic nanocrystals. As the mean size increases with annealing time, this enhancement rapidly diminishes and the peak energy shifts further to the red than the intrinsic nanocrystals. These results indicate the existence of competing pathways for the donor electron, which depends strongly on the nanocrystal size. In samples containing a large density of relatively small nanocrystals, the tendency of phosphorus to accumulate at the nanocrystal-oxide interface means that ionization results in a passivation of dangling bond (Pb -centre) type defects, through a charge compensation mechanism. As the size distribution evolves with isothermal annealing, the density of large nanocrystals increases at the expense of smaller nanocrystals, through an Ostwald ripening mechanism, and the majority of phosphorus atoms occupy substitutional lattice sites within the nanocrystals. As a consequence of the smaller band-gap, ionization of phosphorus donors at these sites increases the free carrier concentration and opens up an efficient, non-radiative de-excitation route for photo-generated electrons via Auger recombination. This effect is exacerbated by an enhanced diffusion in phosphorus doped glasses, which accelerates silicon nanocrystal growth

    ‘Race’ Talk! Tensions and Contradictions in Sport and PE

    Get PDF
    Background: The universal sport discourses of inclusion, belonging, meritocracy, agency, and equality are so widespread that few challenge them. It is clear from the most cursory interest in sport, PE and society that the lived reality is quite different and ambiguous. Racial disparities in the leadership and administration of sport are commonplace world wide; yet from research into ‘race’ in sport and PE the public awareness of these issues is widespread, where many know that racism takes place it is always elsewhere For many this racism is part of the game and something that enables an advantage to be stolen, for others it is trivial and not worthy of deeper thought. This paper explores the contradictions and tensions of the author’s experience of how sport and PE students talk about ‘race’. ‘Race’ talk is considered here in the context of passive everyday ‘race’ talk, dominant discourses in sporting cultures, and colour-blindness. This paper focuses on the pernicious yet persistent nature of ‘race’ talk while demystifying its multifarious, spurious, and more persuasive daily iterations. Theoretical framework: Drawing on Guinier and Torres’ (2003) ideas of resistance through political race consciousness and Bonilla-Silva’s (2010) notion of colour-blindness the semantics of ‘race’ and racialisation in sport and PE are interrogated through the prism of Critical Race Theory (CRT). Critical race scholarship has been used in sport and PE to articulate a political application of ‘race’ as a starting point for critical activism, to disrupt whiteness, and to explore the implications of ‘race’ and racism. CRT is used here to centre ‘race’ and racialised relations where disciplines have consciously or otherwise excluded them. Importantly, the centreing of ‘race’ by critical race scholars has advanced a strategic and pragmatic engagement with this slippery concept that recognises its paradoxical but symbolic location in social relations. Discussion: Before exploring ‘race’ talk in the classroom, using images from the sport media as a pedagogical tool, the paper considers how effortlessly ‘race’ is recreated and renewed. The paper then turns to explore how the effortless turn to everyday ‘race’ talk in the classroom can be viewed as an opportunity to disrupt common racialised assumptions with the potential to implicate those that passively engage in it. Further the diagnostic, aspirational and activist goals of political race consciousness are established as vehicles for a positive sociological experience in the classroom. Conclusion: The work concludes with a pragmatic consideration of the uses and dangers of passive everyday ‘race’ talk and the value of a political race consciousness in sport and PE. Part of the explanation for the perpetuation of ‘race’ talk and the relative lack of concern with its impact in education and wider society is focused on how the sovereignty of sport and PE trumps wider social concerns of ‘race’ and racism because of at least four factors 1) the liberal left discourses of sporting utopianism 2) the ‘race’ logic that pervades sport, based upon the perceived equal access and fairness of sport as it coalesces with the, 3) 'incontrovertible facts' of black and white superiority [and inferiority] in certain sports, ergo the racial justifications for patterns of activity in sport and PE 4) the racist logic of the Right perpetuated through a biological reductionism in sport and PE discourses.

    Negotiating the Coaching Landscape: Experiences of Black men and women coaches in the United Kingdom

    Get PDF
    The current article provides a critical examination of the racialised and gendered processes that reinforce disparities in sport coaching by exploring the experiences of Black men and women coaches in the United Kingdom. The findings are based on in-depth qualitative interviews with coaches from two national governing bodies of sport. Using a Critical Race Theory approach and Black feminist lens, the coaches’ narratives illuminate the complex, multifaceted and dynamic ways in which ‘race’, ethnicity and gender are experienced and negotiated by sport coaches. The coaches’ reflections are discussed under three themes: negotiating identities; privilege and blind spots; and systemic discrimination. The narratives from the coaches’ experiences emphasise the need for key stakeholders in sport to recognise the intersectional, structural and relational experiences that facilitate, as well as constrain, the progression of Black coaches in order to challenge racialised and gendered inequalities

    Strangers of the north: South Asians, cricket and the culture of ‘Yorkshireness’

    Get PDF
    As a county, Yorkshire is what Wagg and Russell refer to as a ‘cultural region’: an imagined space, where culture is constructed, refined and articulated by a set of discursive relationships between local populations and a whole range of cultural forms. In this context however, culture is conceived as something which belongs to, and is only accessible by, certain groups of people. Our focus in this article is on the culture of Yorkshire cricket. Historically, Yorkshire cricket has been linked with white male privilege and some studies have shown that people within Yorkshire take a degree of pride in this. Consequently, the county and its cricket club have faced frequent accusations from minority ethnic communities of inveterate and institutionalised racism. Drawing upon Bauman’s notion of ‘liquid modernity’, we argue that the processes of deregulation and individualisation championed by New Right policies have led to a divorce between power and politics, a corner stone of the old solid modern world. This in turn has led to an erosion of the state, causing individuals to navigate turbulent life projects which are consistently haunted by the spectres of fear and insecurity. Such an environment has caused cricket to be pushed further behind gated social spaces, in an attempt to maintain a semblance of ‘community’

    Non-linear microwave impedance of short and long Josephson Junctions

    The non-linear dependence on applied acac field (bωb_{\omega}) or current (iω% i_{\omega}) of the microwave (ac) impedance Rω+iXωR_{\omega}+iX_{\omega} of both short and long Josephson junctions is calculated under a variety of excitation conditions. The dependence on the junction width is studied, for both field symmetric (current anti-symmetric) and field anti-symmetric (current symmetric) excitation configurations.The resistance shows step-like features every time a fluxon (soliton) enters the junction, with a corresponding phase slip seen in the reactance. For finite widths the interference of fluxons leads to some interesting effects which are described. Many of these calculated results are observed in microwave impedance measurements on intrinsic and fabricated Josephson junctions in the high temperature superconductors, and new effects are suggested. When a % dc field (bdcb_{dc}) or current (idci_{dc}) is applied, interesting phase locking effects are observed in the ac impedance ZωZ_{\omega}. In particular an almost periodic dependence on the dc bias is seen similar to that observed in microwave experiments at very low dc field bias. These results are generic to all systems with a cos(ϕ)\cos (\phi) potential in the overdamped limit and subjected to an ac drive.Comment: 7 pages, 11 figure
