Dynamics of the martial arts high front kick     

Henrik S⊘rensen  Morten Zacho  Erik B. Simonsen  Poul Dyhre‐Poulsen  Klaus Klausen 《Journal of sports sciences》2013,31(6):483-495

Fast unloaded movements (i.e. striking, throwing and kicking) are typically performed in a proximo‐distal sequence, where initially high proximal segments accelerate while distal segments lag behind, after which proximal segments decelerate while distal segments accelerate. The aims of this study were to examine whether proximal segment deceleration is performed actively by antagonist muscles or is a passive consequence of distal segment movement, and whether distal segment acceleration is enhanced by proximal segment deceleration. Seventeen skilled taekwon‐do practitioners were filmed using a high‐speed camera while performing a high front kick. During kicking, EMG recordings were obtained from five major lower extremity muscles. Based on the kinematic data, inverse dynamics computations were performed yielding muscle moments and motion‐dependent moments. The results indicated that thigh deceleration was caused by motion‐dependent moments arising from lower leg motion and not by active deceleration. This was supported by the EMG recordings. Lower leg acceleration was caused partly by a knee extensor muscle moment and partly by a motion‐dependent moment arising from thigh angular velocity. Thus, lower leg acceleration was not enhanced by thigh deceleration. On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration.  相似文献

Causes and consequences of harsh parental punishment: An empirical investigation in a representative sample of 570 German families     

Anette Engfer  Klaus A. Schneewind 《Child abuse & neglect》1982,6(2):129-139

This article examines a multifactorial model of causes and consequences of harsh parental punishment. The social-psychological model as developed by Gelles was extended to also include the antecedent conditions leading to rigid assertion of parental power relating to the child. Furthermore, personality problems of the child observable as consequences of harsh parental punishment were included in our model. The conditions which predict harsh parental punishment are— in the rank order of their importance: a child perceived as difficult to handle, i.e., a “problem child”; parental angerproneness; the rigid assertion of parental power; and intra-familial problems and conflicts. As consequences of harsh parental punishment and rejection as perceived by the child, two types of personality problems were observed: a syndrome named “Conduct Disorder” and a syndrome including personality problems such as anxiety and helplessness.  相似文献   

Streber als Leistungsverweigerer?

Zusammenfassung Wer Schule in Deutschland und in Nordamerika vergleichend beobachtet, dem fallen bald für den Alltag von Schülerinnen und Schülern relevante Unterschiede auf, die in der erziehungswissen-schaftlichen Forschung bisher kaum bearbeitet wurden: Hierzu geh?rt — neben der unterschie dlichen Bewertung des in Nordamerika verp?nten, in Deutschland aber fast zum guten Ton geh?renden ‘cheating’/Schummelns — die Bewertung guter Schulleistungen durch Peers. W?hrend gute Leistungen in Nordamerika unter Peers hoch im Kurs zu stehen scheinen, werden sie in Deutschland — insbesondere in der Sekundarstufe I — oft mit dem Strebervorwurf belegt. Der hier vorgelegte Text wendet sich der Frage zu, ob der Strebervorwurf Auswirkungen auf tats?chliche Schulleistungen im Bereich der Mathematik hat. Er vertritt die These, dass befürchtete negative Peer-Sanktionen als Folge besonders guter Leistungen in Mathematik bei guten Schülern und insbesondere bei leistungsstarken M?dchen die Aussch?pfung des vorhandenen Leistungspotentials begrenzt und auf Dauer auch die Leistungsf?higkeit reduziert. Vorgestellt wird zum einen die Forschungsidee eines im DFG-Schwerpunktprogramm „Bildungsqualit?t von Schule“ gef?rderten Projekts, zum anderen erstes empirisches Material aus zwei Vorerhebungen des Projekts, mit dem die empirische Plausibilit?t der Forschungsidee untermauert werden soll.

Summary Do Nerds Refuse Achievement? Project idea and first data from a study on mathematical achievement Whoever compares schooling in Germany and North America, will soon come across differences with everyday relevance for the school life of students that have rarely been addressed in educational research: Besides the different attitudes towards cheating — being a complete taboo in North America, but a lesser sin in Germany — there is the attitude towards high achievement by peers. Whereas in North America high achievement seems highly valued, high-achieving students in Germany are often accused of being nerds or teacher’s pets, particularly in grades 7–10. The present article deals with the extent to which the nerd accusation has consequences for real achievement in mathematics. The hypothesis is formulated that fear of negative sanctions by peers, as a consequence of being particularly good in math, encourages high achievers to reduce their efforts. Particularly among high-achieving grils, this is presumed to even affect the objective achievement potential in math in the long run. Firstly, the research idea for a study funded by the German Research Council (DFG) in the framework of its focal program on “Quality of Education in Schools” is presented. Secondly, first empirical material from two pilot studies is presented in order to underscore the plausibility of the research idea.

Societal and Organisational Factors of Stress on Students in School     

Klaus Hurrelmann 《欧洲师范教育杂志》1984,7(2):181-190

In this paper an attempt is made both to discuss factors of stress in 14‐ to 18‐year‐old teenage students in and out of school and at the same time to point out the adolescent's own subjective perception of some of those factors by means of an empirical investigation. Factors external and internal to school must be seen as standing in a close relation of interaction to each other. The kind and intensity of mental and social stress is explained by combining an ‘objective’ analysis with a ‘subjective’ one. School is looked at both as a system of social order, organisation and interaction, and as a realm of experience and a social environment for students. On the basis of these considerations, the conception of ‘stress’ is discussed in the context of a meta‐theoretical model of the subject who is productively managing his or her reality.  相似文献   

The Transition to Reaching: Mapping Intention and Intrinsic Dynamics   总被引：9，自引：0，他引：9

The onset of directed reaching demarks the emergence of a qualitatively new skill. In this study we asked how intentional reaching arises from infants' ongoing, intrinsic movement dynamics, and how first reaches become successively adapted to the task. We observed 4 infants weekly in a standard reaching task and identified the week of first arm-extended reach, and the 2 weeks before and after onset. The infants first reached at ages ranging from 12 to 22 weeks, and they used different strategies to get the toy. 2 infants, whose spontaneous movements were large and vigorous, damped down their fast, forceful movements. The 2 quieter infants generated faster and more energetic movements to lift their arms. The infants modulated reaches in task-appropriate ways in the weeks following onset. Reaching emerges when infants can intentionally adjust the force and compliance of the arm, often using muscle coactivation. These results suggest that the infant central nervous system does not contain programs that detail hand trajectory, joint coordination, and muscle activation patterns. Rather, these patterns are the consequences of the natural dynamics of the system and the active exploration of the match between those dynamics and the task.  相似文献
