Jean Vigo’s Zéro de conduite and the spaces of revolt     

Bruno Vanobbergen  Ian Grosvenor  Frank Simon 《Paedagogica Historica: International Journal of the History of Education》2014,50(4):443-459

In this article we will contribute to the contemporary theoretical debate about film by considering, from a history-of-education perspective, the film Zéro de conduite by Jean Vigo (1905–1934). This film is classified under the umbrella of “poetic realism”: a product of cinéma de gauche and an avant-gardist, surrealist and anarchist-catalogued film by a film-maker described by many as very talented and creative. The paper is divided into five parts. In the first part we sketch Vigo’s own biography and the social biography of the film. The second section documents the response to the film both at the time of its release and subsequently. In the third section we explore anarchist ideas about education both in theory and practice. In the fourth section we use this understanding to analyse the film. The final section returns to the question of film as an underused resource and the possibilities of bringing new elements into historical practice.  相似文献

Abstract

This study investigated the influence of interpersonal coordination tendencies on performance outcomes of 1-vs-1 sub-phases in youth soccer. Eight male developing soccer players (age: 11.8 ± 0.4 years; training experience: 3.6 ± 1.1 years) performed an in situ simulation of a 1-vs-1 sub-phase of soccer. Data from 82 trials were obtained with motion-analysis techniques, and relative phase used to measure the space-time coordination tendencies of attacker-defender dyads. Approximate entropy (ApEn) was then used to quantify the unpredictability of interpersonal interactions over trials. Results revealed how different modes of interpersonal coordination emerging from attacker-defender dyads influenced the 1-vs-1 performance outcomes. High levels of space-time synchronisation (47%) and unpredictability in interpersonal coordination processes (ApEn: 0.91 ± 0.34) were identified as key features of an attacking player's success. A lead-lag relation attributed to a defending player (34% around ?30° values) and a more predictable coordination mode (ApEn: 0.65 ± 0.27, P < 0.001), demonstrated the coordination tendencies underlying the success of defending players in 1-vs-1 sub-phases. These findings revealed how the mutual influence of each player on the behaviour of dyadic systems shaped emergent performance outcomes. More specifically, the findings showed that attacking players should be constrained to exploit the space-time synchrony with defenders in an unpredictable and creative way, while defenders should be encouraged to adopt postures and behaviours that actively constrain the attacker's actions.  相似文献   

Dynamics of players’ relative positioning during baseline rallies in tennis

Abstract

This study analysed how the relative positioning of players on court influenced patterns of interpersonal coordination in baseline rallies in tennis. We developed a model (PA index) that assigns a weight to the position of each player on court and determines a positional advantage, based on the relative proportionality between the lateral and longitudinal displacement values during rallies. To test the model, data from 27 randomly-selected baseline rallies from three ATP World Tour matches (professional tennis players' tournaments organized by Association of Tennis Professionals) on clay were analysed. Results revealed that the PA index of players on court described their interpersonal coordination dynamics during baseline rallies. It also identified the emergence of rally breaks in the interpersonal coordination patterns of competing dyads that led to a point being scored. Data suggest that positional advantage data may assist coaches in the design of training tasks to enhance players' court coverage and performance during competitive interactions, acting as a valuable tool for performance analysis in tennis.  相似文献   

How Many Brains Does It Take to Build a New Light: Knowledge Management Challenges of a Transdisciplinary Project     

Bruno della Chiesa  Vanessa Christoph  and Christina Hinton 《Mind, Brain, and Education》2009,3(1):17-26

ABSTRACT— The Organization for Economic Cooperation and Development's (OECD) Center for Educational Research and Innovation (CERI) carried out the Learning Sciences and Brain Research project (1999–2007) to investigate how neuroscience research can inform education policy and practice. This transdisciplinary project brought many challenges. Within the political community, participation in the project varied, with some countries resisting approval of the project altogether, in the beginning. In the neuroscientific community, participants struggled to represent their knowledge in a way that would be meaningful and relevant to educators. Within the educational community, response to the project varied, with many educational researchers resisting it for fear that neuroscience research might make their work obsolete. Achieving dialogue among these communities was even more challenging. One clear obstacle was that participants had difficulty recognizing tacit knowledge in their own field and making this knowledge explicit for partners in other fields. This article analyzes these challenges through a knowledge management framework.  相似文献   

Constraints on competitive performance of attacker-defender dyads in team sports     

Vilar L  Araújo D  Davids K  Travassos B 《Journal of sports sciences》2012,30(5):459-469

Previous research on coordination dynamics of 1 vs. 1 sub-phases in team sports has reported stable emergent patterns of coordination in the displacement trajectories of attackers and defenders. The aim of this study was to use attacker-defender interactions in competitive team match-play to investigate how the locations of the goal and ball constrain the pattern-forming dynamics of attacker-defender dyadic systems. Ten high-level futsal matches were filmed and 13 goal sequences selected for analysis. Displacements of the players and the ball were filmed and digitized from 52 attacker-defender dyadic system interactions. Results showed that, although attackers and defenders exhibited similar angular orientations to the goal, the latter always remained closer to the goal than attackers. Observations revealed that in-phase patterns of coordination emerged from changes to both the distances and angles of attackers and defenders to the goal. Attackers always remained closer to the ball than defenders, while the latter exhibited a lower angle to the ball than attackers. A pattern of in-phase coordination modes emerged between the attackers and defenders' distances and angles to the ball. This study helps us to understand interpersonal interactions in team sports by explaining how attackers and defenders use information about their relative positioning to the goal and the ball to perform successfully.  相似文献

BMI group-related differences in physical fitness and physical activity in preschool-age children: a cross-sectional analysis   总被引：1，自引：0，他引：1  

Niederer I  Kriemler S  Zahner L  Bürgi F  Ebenegger V  Marques P  Puder JJ 《Research quarterly for exercise and sport》2012,83(1):12-19

In the Ballabeina study, we investigated age- and BMI-group-related differences in aerobic fitness (20 m shuttle run), agility (obstacle course), dynamic (balance beam) and static balance (balance platform), and physical activity (PA, accelerometers) in 613 children (M age = 5.1 years, SD = 0.6). Normal weight (NW) children performed better than overweight (OW) children in aerobic fitness, agility, and dynamic balance (all p <.001), while OWchildren had a better static balance (p < .001). BMI-group-related differences in aerobic fitness and agility were larger in older children (p for interaction with age = .01) in favor of the NW children. PA did not differ between NW and OW (p > or = .1), but did differ between NW and obese children (p < .05). BMI-group-related differences in physical fitness can already be present in preschool-age children.  相似文献
