Targeting Mr Average: Participation, gender equity and school sport partnerships
The School Sport Partnership Programme (SSPP) is one strand of the national strategy for physical education and school sport in England, the physical education and school sport Club Links Strategy (PESSCL). The SSPP aims to make links between school physical education (PE) and out of school sports participation, and has a particular remit to raise the participation levels of several identified under-represented groups, of which girls and young women are one. National evaluations of the SSPP show that it is beginning to have positive impacts on young people's activity levels by increasing the range and provision of extra curricular activities (Office for Standards in Education (OFSTED), 2003, 2004, 2005; Loughborough Partnership, 2005, 2006). This paper contributes to the developing picture of the phased implementation of the programme by providing qualitative insights into the work of one school sport partnership with a particular focus on gender equity. The paper explores the ways in which gender equity issues have been explicitly addressed within the 'official texts' of the SSPP; how these have shifted over time and how teachers are responding to and making sense of these in their daily practice. Using participation observation, interview and questionnaire data, the paper explores how the coordinators are addressing the challenge of increasing the participation of girls and young women. The paper draws on Walby's (2000) conceptualisation of different kinds of feminist praxis to highlight the limitations of the coordinators' work. Two key themes from the data and their implications are addressed: the dominance of competitive sport practices and the PE professionals' views of targeting as a strategy for increasing the participation of under-represented groups. The paper concludes that coordinators work within an equality or difference discourse with little evidence of the transformative praxis needed for the programme to be truly inclusive. © 2008 Taylor & Francis
Engineering Cell–ECM–Material Interactions for Musculoskeletal Regeneration
The extracellular microenvironment regulates many of the mechanical and biochemical cues that direct musculoskeletal development and are involved in musculoskeletal disease. The extracellular matrix (ECM) is a main component of this microenvironment. Tissue engineered approaches towards regenerating muscle, cartilage, tendon, and bone target the ECM because it supplies critical signals for regenerating musculoskeletal tissues. Engineered ECM–material scaffolds that mimic key mechanical and biochemical components of the ECM are of particular interest in musculoskeletal tissue engineering. Such materials are biocompatible, can be fabricated to have desirable mechanical and biochemical properties, and can be further chemically or genetically modified to support cell differentiation or halt degenerative disease progression. In this review, we survey how engineered approaches using natural and ECM-derived materials and scaffold systems can harness the unique characteristics of the ECM to support musculoskeletal tissue regeneration, with a focus on skeletal muscle, cartilage, tendon, and bone. We summarize the strengths of current approaches and look towards a future of materials and culture systems with engineered and highly tailored cell–ECM–material interactions to drive musculoskeletal tissue restoration. The works highlighted in this review strongly support the continued exploration of ECM and other engineered materials as tools to control cell fate and make large-scale musculoskeletal regeneration a reality

Critical affection: an expanded portrait of the artist-as-player in digital cultures
Digital cultures engage users’ social, creative and emotional labour – a process that can be described as affective. For some theorists and artists, this dynamic is inherently exploitative. However, within this exploitation is the potential, particularly in social media and games, to provide fuel for playful critique. The concept of ‘play’ is frequently used to describe users’ engagement within such cultures. This phenomenon evokes a long history in the arts of deploying ‘critical play’ modalities. In light of this situation, how might we begin to sketch a broader portrait of a ‘player’ engaging with the site of ‘critical play’? This PhD project explores this question through a mapping of artists’ critical play within digital environments. With the focus upon affective engagement in digital environments, I argue that it is the reflection and interrogation of processes of identity representation that, in turn, drive much of the motivation for ‘playing critically’ as a productive probe. More generally ‘Critical Affection, an expanded portrait of the artist-as-player in digital cultures’ seeks to contribute to play debates at the intersection of games studies, new media and contemporary art
A recurrent neural network with ever changing synapses
A recurrent neural network with noisy input is studied analytically, on the
basis of a Discrete Time Master Equation. The latter is derived from a
biologically realizable learning rule for the weights of the connections. In a
numerical study it is found that the fixed points of the dynamics of the net
are time dependent, implying that the representation in the brain of a fixed
piece of information (e.g., a word to be recognized) is not fixed in time.Comment: 17 pages, LaTeX, 4 figure
Deconstructing health and physical education teacher education: a mapping and analysis of programme structure and content in Australia
Background: In Australia, Initial Teacher Education Institutions (ITEIs) provide undergraduate Health and Physical (HPE) programmes that meet a number of regulatory requirements, including those of the Australian Institute for Teaching and School Leadership (AITSL) and the Tertiary Education Quality and Standards Agency (TEQSA). In addition, ITEIs must also ensure programme alignment with state/territory-based jurisdictional requirements. While historically varied philosophies and practices have shaped HPE teacher education nationally, ITEIs are thus operating in an increasingly regulated environment.
Purpose: The purpose of this paper is to report research that has critically examined the structure and content of ITEI undergraduate programmes in Australia that prepare teachers for HPE in secondary schools. Analysis at programme and unit levels was undertaken to explore programme variance, ITEI priorities and consideration of the implications that programme structure and content has for graduate secondary HPE teachers and their employers. The paper seeks to contribute to wider debates about the role of teacher education in shaping HPE curriculum futures and the challenges faced by ITEIs to navigate increasing government regulation.
Methods: An audit and document analysis of 15 Australian ITEIs identified programme structures and specific units of study for the preparation of secondary HPE teachers. These programme structures were compared to those of an ITEI in Western Australia (WA), similarly preparing secondary teachers of HPE, and undertaking internal programme renewal. The WA ITEI’s programme nomenclature and elements therefore provided the reference point for analysis of variation across programmes nationally.
Findings: Findings show that graduate secondary HPE teachers in Australia are variously prepared, with ITEI programme structures ranging in nomenclature, breadth of content, positioning of units and the amount and placement of school-based practicums. ITEIs variously meet state, territory and federal accountability and accreditation requirements in preparing secondary HPE teachers. Programme variations may mean that graduate secondary HPE teachers have differing perspectives on HPE curriculum and pedagogy. Schools employing graduate teachers cannot assume all graduate teachers have a common outlook on or backgrounds in HPE, while meeting the graduate standards.
Conclusions: The significant variation between programme structure and content at the 15 ITEIs preparing teachers for HPE in secondary schools indicates that in a heavily regulated sector, ITEIs in Australia remain critical players in shaping HPE practices across Australian schools. Further research is needed to appropriately ascertain the impact of ITEI programme variation on HPE teachers’ values and professional practice
Hierarchical Self-Programming in Recurrent Neural Networks
We study self-programming in recurrent neural networks where both neurons
(the `processors') and synaptic interactions (`the programme') evolve in time
simultaneously, according to specific coupled stochastic equations. The
interactions are divided into a hierarchy of groups with adiabatically
separated and monotonically increasing time-scales, representing sub-routines
of the system programme of decreasing volatility. We solve this model in
equilibrium, assuming ergodicity at every level, and find as our
replica-symmetric solution a formalism with a structure similar but not
identical to Parisi's -step replica symmetry breaking scheme. Apart from
differences in details of the equations (due to the fact that here
interactions, rather than spins, are grouped into clusters with different
time-scales), in the present model the block sizes of the emerging
ultrametric solution are not restricted to the interval , but are
independent control parameters, defined in terms of the noise strengths of the
various levels in the hierarchy, which can take any value in [0,\infty\ket.
This is shown to lead to extremely rich phase diagrams, with an abundance of
first-order transitions especially when the level of stochasticity in the
interaction dynamics is chosen to be low.Comment: 53 pages, 19 figures. Submitted to J. Phys.
A Phenomenological Approach to Understanding the Impact of Chronic Ear Disease on Wellbeing in Young People: Patient and Carer Perspectives.
Background: Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of the middle ear which usually occurs in childhood. Symptoms of CSOM include ear pain, an odorous discharge and hearing loss, necessitating significant medical intervention. Previous research has largely focused on functional outcomes of CSOM using quantitative methods. Consequently, the lived experience of this condition from patient and carer perspectives is relatively unknown. The aim of the current study is to qualitatively explore the psychological impact of CSOM on young people.
Methods: A qualitative semi-structured interview design is proposed. Up to 10 young people aged 12-18 and their primary caregivers will be recruited from local ENT clinics and interviewed individually. Interviews will consider participants’ experience of the meaning of CSOM, its impact on identity and social and emotional aspects of daily life. Interviewing both patients and primary caregivers about the same phenomena will enable triangulation of the data. All interviews will be audio recorded and transcribed verbatim. Data will be analysed using Interpretative Phenomenological Analysis (IPA).
Findings: IPA will be conducted on patient and primary caregiver interview data according to the process outlined in Smith, Larkin and Flowers (2009). Initial findings will be shared with the young people and their primary caregivers.
Discussion: The findings from the current study will lead to a greater understanding of CSOM on young people’s wellbeing and quality of life. This knowledge will enable ENT clinics and other medical teams to address the psychosocial support needs of this group and ultimately improve patient care
A solvable model of the genesis of amino-acid sequences via coupled dynamics of folding and slow genetic variation
We study the coupled dynamics of primary and secondary structure formation
(i.e. slow genetic sequence selection and fast folding) in the context of a
solvable microscopic model that includes both short-range steric forces and and
long-range polarity-driven forces. Our solution is based on the diagonalization
of replicated transfer matrices, and leads in the thermodynamic limit to
explicit predictions regarding phase transitions and phase diagrams at genetic
equilibrium. The predicted phenomenology allows for natural physical
interpretations, and finds satisfactory support in numerical simulations.Comment: 51 pages, 13 figures, submitted to J. Phys.
