The social construction of pedagogic discourse in policy for physical education and school sport

A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of PhilosophyOver the past decade in the UK, the rise in salience to government of physical education and school sport-related policy interventions has been remarkable for the wide-ranging array of objectives that these interventions have been expected to realise. This thesis analyses and evaluates government's sports policy for PESS centred on the Physical Education, School Sport and Club Links (PESSCL) strategy and Physical Education and Sport Strategy for Young People (PESSYP). These strategies together arguably represent the most significant initiatives relating to physical education and school sport (PESS), shaping the possible forms of PESS could take in the 2000s. Drawing on Basil Bernstein's (1990, 1996) theory of the social production of pedagogic discourse as the main framework used to investigate the policy for PESS, this thesis discusses the complexities and inequalities of policy-making in terms of examining dominant physical cultural discourses embedded within PESSCL and PESSYP, and the main agents/agencies contributing to the policy for PESS and evaluation processes. In addition, this thesis adopted a grounded theory approach to look at patterns of evidence in a range of resources from policy documents, newspapers, official evaluation studies and interviews, analyses that were underpinned by the research aims and theoretical framework of the study. This thesis identifies a number of physical cultural discourses constructing and constituting policies and strategies for PESS, including discourses of sport, health, citizenship, lifelong participation, and Olympic/Paralympic legacy. Moreover, this thesis presents evidence, consistent with Goodson‟s (1990) thesis about the social construction of school subjects, of struggles and contestation among vying groups, in this case between the Youth Sport Trust and Sport England (i.e. within the Official Recontextualising Field) as well as between the Youth Sport Trust and Association for Physical Education (i.e. between agencies within the Official Recontextualising Field and Pedagogic Recontextualising Field respectively). Furthermore, the powerful recontextualising agents/agencies including the media contribute to the recontextualisation of the discourse in which PESS policies are embedded. Finally, this thesis questions whether the main official evaluation studies undertake "evidence-based‟ policy making and practice because the evaluation studies not only provide implausible evidence but they are also focused solely on "numbers‟, whilst pragmatic and critical voices are excluded from the process of evaluation. Building on these key findings, this thesis concludes with a discussion of the implications for PESS. In particular, I discuss the possibilities for PESS to realise authentic forms of physical culture in schools in the context of a dominant sport discourse and an ongoing reduction in the autonomy of the Pedagogic Recontextualising Field. Finally, this thesis suggests that there is an urgent need for promoting communication between policy makers from within the Official Recontextualising Field and researchers and educators from within the Pedagogic Recontextualising Field and practitioners in the Secondary Field in order to achieve sustainable policy development school physical education and youth sport that benefits all young people in the future

TRAO Survey of Nearby Filamentary Molecular clouds, the Universal Nursery of Stars (TRAO FUNS) I. Dynamics and Chemistry of L1478 in the California Molecular Cloud

"TRAO FUNS" is a project to survey Gould Belt's clouds in molecular lines. This paper presents its first results on the central region of the California molecular cloud, L1478. We performed On-The-Fly mapping observations using the Taedeok Radio Astronomy Observatory (TRAO) 14m single dish telescope equipped with a 16 multi-beam array covering $\sim$1.0 square degree area of this region using C$^{18}$O (1-0) mainly tracing low density cloud and about 460 square arcminute area using N$_{2}$H$^{+}$ (1-0) mainly tracing dense cores. CS (2-1) and SO $(3_{2}-2_{1})$ were also used simultaneously to map $\sim$440 square arcminute area of this region. We identified 10 filaments by applying the dendrogram technique to the C$^{18}$O data-cube and 8 dense N$_{2}$H$^{+}$ cores by using {\sc FellWalker}. Basic physical properties of filaments such as mass, length, width, velocity field, and velocity dispersion are derived. It is found that L1478 consists of several filaments with slightly different velocities. Especially the filaments which are supercritical are found to contain dense cores detected in N$_{2}$H$^{+}$. Comparison of non-thermal velocity dispersions derived from C$^{18}$O and N$_{2}$H$^{+}$ for the filaments and dense cores indicates that some of dense cores share similar kinematics with those of the surrounding filaments while several dense cores have different kinematics with those of their filaments. This suggests that the formation mechanism of dense cores and filaments can be different in individual filaments depending on their morphologies and environments.Comment: 25 pages, 15 figures, accepted for publication in Ap

Deformable Graph Transformer

Transformer-based models have recently shown success in representation learning on graph-structured data beyond natural language processing and computer vision. However, the success is limited to small-scale graphs due to the drawbacks of full dot-product attention on graphs such as the quadratic complexity with respect to the number of nodes and message aggregation from enormous irrelevant nodes. To address these issues, we propose Deformable Graph Transformer (DGT) that performs sparse attention via dynamically sampled relevant nodes for efficiently handling large-scale graphs with a linear complexity in the number of nodes. Specifically, our framework first constructs multiple node sequences with various criteria to consider both structural and semantic proximity. Then, combining with our learnable Katz Positional Encodings, the sparse attention is applied to the node sequences for learning node representations with a significantly reduced computational cost. Extensive experiments demonstrate that our DGT achieves state-of-the-art performance on 7 graph benchmark datasets with 2.5 - 449 times less computational cost compared to transformer-based graph models with full attention.Comment: 16 pages, 3 figure

A situation-aware cross-platform architecture for ubiquitous game

Multi-player online games (MOGs) are popular in these days. However, contemporary MOGs do not really support ubiquity in the sense that a seamless service across heterogeneous hardware platforms is not provided. This paper presents the architecture of the cross-platform online game, which provides a service to users from heterogeneous platforms and is equipped with a situation-aware capability for enabling the users to seamlessly move between heterogeneous platforms. The experimental results through the prototype implementations show the feasibility of the situation-aware cross-platform game
