La psicomotricidad en la escuela     

D. Pérez  F. Ramos  M. Rodríguez 《Infancia y Aprendizaje》2013,36(9):105-109

RESUMEN

La psicomotricidad juega un papel muy importante en el desarrollo neuropsicológico del niño. En España los planteamientos de la Educación Psicomotriz han estado orientados hacia la reeducación y la terapia. En consecuencia, se hace necesario integrar la Educación Psicomotriz dentro del contexto escolar, desde los primeros años.  相似文献

Connecting others: Does a tertius iungens orientation shape the relationship between research networks and innovation?     

Oscar Llopis  Pablo D'Este  Adrián A. Díaz-Faes 《Research Policy》2021,50(4):104175

Research on social networks and innovation emphasizes that individuals spanning structural holes and crossing institutional boundaries have more opportunities for knowledge recombination and innovation involvement. However, transforming the potential knowledge and resources available through personal networks to attain innovation can be difficult for the focal individual. Using an ego-network approach, this study examines whether and to what extent an individual strategic orientation to cooperation (i.e. tertius iungens) contributes to strengthening the relation between two personal network properties (structural and institutional separation) and involvement in innovation. Our analysis is conducted in the context of biomedicine, where research networks are particularly relevant for science and innovation achievements. Our findings advance social network theory by decoupling social network mechanisms from individual strategic networking behavior as factors influencing knowledge generation processes. Results also provide original evidence on an overlooked phenomenon: the moderating role of a tertius iungens orientation in the relationship between multiple social network properties and innovation. Finally, our research sheds new light on the distinct sources of knowledge recombination in networks and the role of individual networking strategies to facilitate mobilization of resources for innovation.  相似文献   

Theoretical and numerical local null controllability of a quasi-linear parabolic equation in dimensions 2 and 3     

E. Fernández-Cara  J. Límaco  I. Marín-Gayte 《Journal of The Franklin Institute》2021,358(5):2846-2871

This paper is devoted to the theoretical and numerical analysis of the null controllability of a quasi-linear parabolic equation. First, we establish a local controllability result. The proof relies on an appropriate inverse function argument. Then, we formulate an iterative algorithm for the computation of the null control and we prove a convergence result. Finally, we illustrate the analysis with some numerical experiments.  相似文献   

Comparison of dynamic visual acuity between water polo players and sedentary students     

Quevedo-Junyent L  Aznar-Casanova JA  Merindano-Encina D  Cardona G  Solé-Fortó J 《Research quarterly for exercise and sport》2011,82(4):644-651

In this study, we examined differences in dynamic visual acuity between elite and subelite water polo players and sedentary students. To measure dynamic visual acuity binocularly, we asked participants to indicate the orientation of a broken ring, similar to the Landolt C, which increased in size as it moved across a computer screen. Two different speeds, three possible trajectories, and two different levels of contrast were evaluated. There were statistically significant differences between elite players and sedentary students for each combination of speed, contrast, and trajectory. Elite players achieved better dynamic visual acuity scores, and results also improved for some combinations of speed, contrast, and trajectory. Comparison between elite and subelite groups failed to reveal any  相似文献   

Fluid balance of elite Brazilian youth soccer players during consecutive days of training     

Silva RP  Mündel T  Natali AJ  Bara Filho MG  Lima JR  Alfenas RC  Lopes PR  Belfort FG  Marins JC 《Journal of sports sciences》2011,29(7):725-732

In this study we investigated pre-training hydration status, fluid intake, and sweat loss in 20 elite male Brazilian adolescent soccer players (mean?±?s: age 17.2?±?0.5 years; height 1.76?±?0.05?m; body mass 69.9?±?6.0?kg) on three consecutive days of typical training during the qualifying phase of the national soccer league. Urine specific gravity (USG) and body mass changes were evaluated before and after training sessions to estimate hydration status. Players began the days of training mildly hypohydrated (USG?>?1.020) and fluid intake did not match fluid losses. It was warmer on Day 1 (33.1?±?2.4°C and43.4?±?3.2% relative humidity; P?相似文献   

Activity profile of top-class association football referees in relation to performance in selected physical tests     

Mallo J  Navarro E  García-Aranda JM  Gilis B  Helsen W 《Journal of sports sciences》2007,25(7):805-813

The aims of the present study were (1) to analyse the physical demands of top-class referees and (2) to compare their official FIFA fitness test results with physical performance during a match. The work rate profiles of 11 international referees were assessed during 12 competitive matches at the 2003 FIFA Under-17 World Cup and then analysed using a bi-dimensional photogrammetric video analysis system based on direct lineal transformation (DLT) algorithms. In the first 15 min of matches, the referees were more active, performing more high-intensity exercise (P < 0.01) than in the first 15 min of the second half. During the second half of matches, the referees covered a shorter distance (P < 0.01), spent more time standing still (P < 0.05), and covered less ground cruising (P < 0.05), sprinting (P < 0.05), and moving backwards (P < 0.001) than in the first half. Also in the second 45 min, the distance of referees from infringements increased (P < 0.05) in the left attacking zone of the filed. There was also a decrease (P < 0.05) in performance in the period following the most high-intensity activity, compared with the mean for the 90 min. Time spent performing high-intensity activities during a match was not related to performance in the 12-min run (r(2) = 0.30; P < 0.05), the 200-m sprint (r(2) = 0.05; P < 0.05), or the 50-m sprint (r(2) = 0.001; P < 0.05). The results of this study show that: (1) top-class referees experienced fatigue at different stages of the match, and (2) the typical field tests used by FIFA (two 50-m and 200-m sprints, followed by a 12-min run) are not correlated with match activities.  相似文献
