In this chapter, the authors describe the situation and challenges of Physical Education (PE) in Flanders and Wallonia in order to encourage young people to adopt a healthy lifestyle and to become critical sports consumers. In school-age children, about one out of six has problems with obesity/overweight. Compared with earlier measurements there is a trend of increasing sedentary time per day and not enough physical activity (PA) to reach international norms. Girls can be definitely considered as a public at risk regarding the physical activity component of their healthy lifestyle. In recent years, the emphasis has shifted from motor- and/or physical-testing towards the development of a positive attitude towards physical activity and being socially engaged. The main concern of the course-specific final attainment levels is teaching how to deal with the current movement culture of games, sports, fitness, and daily activity. In both regions, it is expected that children are taught to transfer movement and personally-related competencies learned in PE to other contexts. Initiatives to develop and enhance links between PE and other opportunities to be physically active in the wider community are receiving more attention during the last few years, but the situation is still far from ideal. Because of the complex role of promoting a healthy lifestyle during PE and in the whole school, there is a need to educate teachers during their teacher training and lifelong education on how to provide relevant choices, satisfying the need for autonomy.

The current society needs to fight against the growing of sedentary lifestyles among the population all around the world. The school environment is identified as a pillar of the multisectorial approach that should be implemented to avoid that children who born today do not live less longer than their parents. The presentation will focus on four topics: (1) The role of school in physical activity (PA) promotion; (2) The dimensions of PA at school; (3) The action that physical education (PE) teacher can play; (4) The role of PE teacher educators in the improvement of the PE adaptation to the current needs. For one child, there are several opportunities to be physically active at school but the part of the school in youth PA is not well documented. Since recently, the only strong evidence of the effectiveness of interventions aiming to promote PA in youth was identified in adolescents when school and family/community environments are combined. However, some reviews have now revealed that school-based PA interventions can be effective for improvements in BMI, motor performance, physical activity, knowledge … In order to design one PA promotion project at school, five dimensions should be considered: (1) Physical education; (2) Sport at school (links to the community); (3) Active transportation; (4) Life environment (recesses, spaces); (5) Physical activity in the classroom. All these dimensions should be supported by a strong school policy that considers PA as a key aspect for the youth development. It means that packages of school-based strategies need to be developed. Nevertheless, PE seems to be a central aspect emphasizing the key role of the PE teachers who should become the PA promoters in every school. Unfortunately, since few decades, PE is facing a worldwide crisis raising questions about its quality and focusing on the teaching process, the inadequate school-community co-ordination, the focus on competition performance sport and the lack of interest on basic human movement and needs. Three concepts are now influencing some changes: (1) The physical literacy; (2) The accountability, and; (3) The Quality Physical Education (QPE). This means that, in PE, a special emphasis should now be set on the acquisition by the youth of knowledge, skills and attitude that will make them physically educated persons for their whole life, with the purpose to reach concrete improvements and to respect students’ needs and motivational characteristics. PE teachers have to show what they are doing in the promotion of an active lifestyle, using sports like a tool for general aims and not as a final objective. On the field, this means that new contents and teaching strategies have to be developed. The involvement of the students and the implementation of their learning into the real life should become a priority. Collaboration with other actors of the educational community (other teachers, parents) or the local community (sport clubs, sport administrations, private sector …) should be developed. PE teachers have to take these new roles. To achieve such change, they need to be supported by the PE teacher educators who have to emphasize the new educating strategies, develop concrete material and resources, contribute to create communities of practice, provide evidence based data supporting the effectiveness of the new approaches. The presentation will propose systematic ‘give and go’ between theory and practice in order to connect researchers and physical education teachers, underlining that PE can only grow with such collaboration and development of a networking.

Literature emphasizes the increasing prevalence of obesity. This phenomenon is related to growing health problems and to their cost for the society in terms of health expenses as well as lack of human well-being. Sedentary lifestyle is systematically pointed out as one of the determining factors at the origin of this situation. WHO (2001) underlined the need of a multifactorial action while Pate et al. (2006) highlighted the school’s central role. Within the school, it seems that the physical education (PE) teacher represents the corner stone of any process aiming to promote physical activity (PA) (USDHHS, 1996; Tappe & Burgeson, 2004). Nevertheless, when determining if PE teachers are ready to be the expected PA promoters, it appears that, in Wallonia (as it could be the case in other countries), several data show that the answer is not really positive. It seems that PE teachers need some support in order to make youths physically active, and adopting a healthy lifestyle. In fact, proposing traditional lessons focusing on sport would not be sufficient to reach these objectives. In this way, PE teacher educators should have two priorities: (1) to clarify the PE teachers’ representations of PA and (2) to identify and share strategies aiming to define their potential actions on the field. The presentation illustrated four approaches that were experimented at the University of Liege in pre- and in-service PE teacher education. The major goal of the speech was to involve the participants by stimulating reflexibility and content development. Four questions have been in the centre of the activity: (1) What is physical Activity? (2) What must be done, finally? (3) How to deal with arguments against practice? (4) What could do PE teachers to promote an active lifestyle? Each question was discussed through distinct approaches that could be used by the participants in their own practice. [less ▲]

Motivational aspects play a particularly important role in teaching. They are considered a powerful mediator between teacher action and teaching effects. Pupils’ motivation towards school and physical education has already been analysed from the pupils’ point of view (Piéron, Ledent, Almond, Airstone and Newsburry, 1996). On another side, its perception by teachers is less documented. This study focused on the identification by PE teachers of pupils’ behaviours indicating that they were motivated or not. Moreover, perception of reasons related to lack of motivation in pupils was also investigated. Twenty-nine teachers fulfilled a questionnaire during an inservice preparation seminar. Their answers were analysed and inductively classified in categories. Thirteen categories of criteria showing the presence or lack of motivation were identified. Motivation was predominantly perceived by (1) the quality of the working climate (16.8%); (2) the intend to be involved in the PE lesson (14%); (3) positive reactions towards the subject matter (11.2%) and an efficient time management (11.2%). The most important categories related to lack of motivation were: (1) absences or excuses (20.2%); (2) low time on task (14%) and (3) negative reactions towards the subject matter (14%). Concerning origins of the lack of motivation, teachers emphasised: (1) the large differences between pupils (13.7%); the lack of sport culture of youth (10.5%) and (3) the negative pupils’ attitude towards school.

Marguerre's shallow shell theory is interpreted by the means of the introduction of a "fictitious initial displacement". A logical interpretation of Marguerre's equilibrium equations follows directly from this point of view. The introduction of fictitious displacements is easy to generalize, and the case of quasi-conical shells is analyzed in detail. [less ▲]

This paper focuses on the relation between the vibration modes of mechanical systems and the modes computed through a blind source separation technique called independent component analysis (ICA). For free and random vibrations of weakly damped systems, a one-to-one relationship between the vibration modes and the ICA modes is demonstrated using the concept of virtual source. Based on this theoretical link, a time-domain structural system identification technique is proposed and is illustrated using numerical examples. [less ▲]

Proper orthogonal decomposition is a statistical pattern analysis technique for finding the dominant structures, called the proper orthogonal modes, in an ensemble of spatially distributed data. While the proper orthogonal modes are obtained through a statistical formulation, they can be physically interpreted in the field of structural dynamics. The purpose of this paper is thus to provide some insights into the physical interpretation of the proper orthogonal modes using the singular value decomposition. (C) 2002 Academic Press. [less ▲]

High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills. Good wear resistance and hardness at high temperatures, are defining features of HSS. Many types of carbides are present in these alloys, each having different effect upon their final properties. As a result, nature, morphology and amount of these carbides are factors of important concern. Identification and characterisation of carbides were realised. MC, M2C, M7C3 carbides were found. Some relationships with mechanical properties were obtained especially in the field of the solidification sequence that affects grain size and carbides dispersion. [less ▲]

Physical modelling is a key tool for generating understanding of the complex interactions between aquatic organisms and hydraulics, which is important for management of aquatic environments under environmental change and our ability to exploit ecosystem services. Many aspects of this field remain poorly understood and the use of physical models within eco-hydraulics requires advancement in methodological application and substantive understanding. This paper presents a review of the emergent themes from a workshop tasked with identifying the future infrastructure requirements of the next generation of eco-hydraulics researchers. The identified themes are: abiotic factors, adaptation, complexity and feedback, variation, and scale and scaling. The paper examines these themes and identifies how progress on each of them is key to existing and future eðorts to progress our knowledge of eco-hydraulic interactions. Examples are drawn from studies on biofilms, plants, and sessile and mobile fauna in shallow water fluvial and marine environments. Examples of research gaps and directions for educational, infrastructural and technological advance are also presented. [less ▲]

WASP-80 is one of only two systems known to contain a hot Jupiter which transits its M-dwarf host star. We present eight light curves of one transit event, obtained simultaneously using two defocussed telescopes. These data were taken through the Bessell I, Sloan griz and near-infrared JHK passbands. We use our data to search for opacity-induced changes in the planetary radius, but find that all values agree with each other. Our data are therefore consistent with a flat transmission spectrum to within the observational uncertainties. We also measure an activity index of the host star of log R'_HK=-4.495, meaning that WASP-80A shows strong chromospheric activity. The non-detection of starspots implies that, if they exist, they must be small and symmetrically distributed on the stellar surface. We model all available optical transit light curves to obtain improved physical properties and orbital ephemerides for the system. [less ▲]
