    Making physical education relevant: Increasing the impact of initial teacher training

    This paper is developed from concern that, despite a number of developments and initiatives in physical education over recent years, there has been little change in the teaching of the subject. This has resulted in many young people being alienated from physical education and therefore physical activity. The paper focuses on how initial teacher training (ITT) contributes to this lack of change by focusing on the development of knowledge for teaching and the technical competence to deliver this. It then considers ways in which ITT could contribute to developing ‘knowledgeable teachers’ who are able to make change. The paper focuses on two aspects identified as relevant for trainee physical education teachers: socialisation and knowledge for teaching. It recognises that the issues are complex and that change is difficult. It also recognises that ITT cannot change things by itself. However, it argues that by maintaining the status quo, the subject will not develop so that it is relevant to today’s youngsters

    OpenPING: A Reflective Middleware for the Construction of Adaptive Networked Game Applications

    The emergence of distributed Virtual Reality (VR) applications that run over the Internet has presented networked game application designers with new challenges. In an environment where the public internet streams multimedia data and is constantly under pressure to deliver over widely heterogeneous user-platforms, there has been a growing need that distributed VR applications be aware of and adapt to frequent variations in their context of execution. In this paper, we argue that in contrast to research efforts targeted at improvement of scalability, persistence and responsiveness capabilities, much less attempts have been aimed at addressing the flexibility, maintainability and extensibility requirements in contemporary distributed VR platforms. We propose the use of structural reflection as an approach that not only addresses these requirements but also offers added value in the form of providing a framework for scalability, persistence and responsiveness that is itself flexible, maintainable and extensible. We also present an adaptive middleware platform implementation called OpenPING1 that supports our proposal in addressing these requirements

    Interoperating with heterogeneous Mobile Services

    Mobile applications are now developed upon a wide range of service development platforms, commonly referred to as middleware. However, the diversity of those available presents a problem for mobile client development. How can a single client implementation interoperate with heterogeneous service implementations

    Psychosocial and educational outcomes of weight faltering in infancy in ALSPAC

    OBJECTIVES: To investigate whether infants with weight faltering have impaired psychosocial and educational outcomes in later childhood. DESIGN: Follow-up of infants with weight faltering in a large UK cohort study. SETTING: The Avon Longitudinal Study of Parents and Children (ALSPAC). PARTICIPANTS: 11 534 term infants from ALSPAC with complete weight records. Weight gain (conditional on initial weight) was calculated for three periods: from birth to 8 weeks, 8 weeks to 9 months, and birth to 9 months. Cases of weight faltering were defined as those infants with a conditional weight gain below the 5th centile, and these were compared with the rest of the cohort as the control group. OUTCOMES: Between 6 and 11 years, social, emotional and behavioural development was measured by direct assessment of the children and parental and teacher report. Educational outcomes included Standardised Assessment Test results at 7 and 11 years and Special Educational Needs status at age 11. RESULTS: Differences seen on univariate analysis in attention, non-verbal accuracy, educational attainment and special educational needs became non-significant after adjustment for confounding. Children with weight faltering in infancy did not differ from controls on any measures of self-esteem, peer relationships, experience of bullying, social cognition, antisocial activities, anxiety, depression or behavioural problems. CONCLUSIONS: Weight faltering in early infancy was associated with poorer educational outcomes in later childhood, but these associations were explained by confounding. The subsequent psychosocial development of infants with slow weight gain was not different from that of their peers
