Circles with a suspended aid: reducing pommel reaction forces     

Toshiyuki Fujihara  Pierre Gervais 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(1):34-47

The aim of this study was to investigate the influence of a suspended aid on the reaction forces during a basic skill on pommel horse. Twenty gymnasts performed three sets of 10 circles with and without a suspended aid on a pommel horse under which two force plates were set. The results confirmed that the suspended aid could reduce the magnitude of the pommel reaction forces during circles while maintaining the general loading pattern. On the left hand, the average and peak forces were attenuated to 0.59 body weight (BW) and 0.85 BW from 0.76 BW and 1.13 BW, respectively. The right hand experienced slightly larger forces with no-aid trials, but the asymmetry between the hands decreased with the aid. Despite a relatively large variability, all gymnasts experienced smaller impact peak forces with the aid. A suspended aid is most commonly used for a beginner gymnast as an introduction to pommel horse exercises. However, this study confirmed that it can also be useful for all levels of gymnasts who would like to practice pommel horse exercises with reduced pommel reaction forces for a purpose such as a progression for learning a new skill, control of training volume, or rehabilitation.  相似文献

Intrafamilial sexual abuse: brother-sister incest does not differ from father-daughter and stepfather-stepdaughter incest     

Cyr M  Wright J  McDuff P  Perron A 《Child abuse & neglect》2002,26(9):957-973

OBJECTIVE: Three groups of girls who were sexually abused (by either brothers, fathers, or stepfathers) were compared. The purpose was to identify the differing characteristics of the abuse, the family environments, and the psychosocial distress of these children. METHOD: Seventy-two girls aged between 5 and 16 were assigned to one of the three groups. Subjects were matched between groups on the basis of their actual age. Children completed measures of traumatic stress; their mothers completed the Child Behavior Checklist-Parent Report Form (CBCL) and other self-report questionnaires on family characteristics. Workers in child protective services completed information regarding the nature and severity of the abuse. RESULTS: Results suggested few differences in the characteristics of sexual abuse between the three groups. However, penetration was much more frequent in the sibling incest group (70.8%) than in the stepfather incest (27.3%) or father incest (34.8%) groups. Ninety percent of the victims of fathers and brothers manifested clinically-significant distress on at least one measure, whereas 63.6% of stepfather victims did. Compared with father and stepfather perpetrators, brothers were raised in families with more children and more alcohol abuse. CONCLUSIONS: The authors conclude that the characteristics of brother-sister incest and its associated psychosocial distress did not differ from the characteristics of father-daughter incest These findings suggest that theoretical models and clinical practices should be adjusted accordingly and that sibling incest should not necessarily be construed as less severe or harmful than father-daughter incest.  相似文献   

A EUROPEAN INSTITUTIONAL AUDIT     

Pierre Tabatoni 《Higher Education in Europe》1995,20(1-2):108-115

The project of CRE for a European institutional audit of higher education institutions is presented, justified, and briefly described. It responds to the increasing concerns of all actors involved in higher education with quality in every meaning of the word. As the integration of Europe proceeds, as course programmes increasingly emphasize inter‐disciplinarity, as students and teachers become increasingly mobile, the role and importance of such a Europe‐wide audit is enhanced.

Cinquante années de débats et de recherches sur l’école française     

Pierre Caspard  Jean-François Condette 《Paedagogica Historica: International Journal of the History of Education》2014,50(6):786-796

Two major factors have contributed to the evolution of French historiography in the history of education in the past 50 years. The first relates to the general orientation of public debate about schools, which has shifted from a paradigm concerning democratisation to one that focuses on student success rates and the efforts to eliminate inequalities of all sorts. The second factor that has affected scholarly orientations lies in changes linked to academic positioning between pedagogy, history, and the educational sciences in the context of increasing university hirings, at least until recently. These two changes in terms of scholarly paradigms and scholarly professional identities have encouraged the development of a certain number of approaches and questions: a reconsideration of the historic role of the State, an interest in a greater diversity of actors in the educational process, and a re-evaluation of the cognitive, cultural and social effects of teaching at all levels. Despite this, the history of education plays a minor role today in France, not only in teacher training but also in debates about the future of schools.  相似文献   

Watching MOOCs together: investigating co-located MOOC study groups     

Nan Li  Himanshu Verma  Afroditi Skevi  Guillaume Zufferey  Jan Blom  Pierre Dillenbourg 《Distance Education》2014,35(2):217-233

Research suggests that massive open online course (MOOC) students prefer to study in groups, and that social facilitation within the study groups may render the learning of difficult concepts a pleasing experience. We report on a longitudinal study that investigates how co-located study groups watch and study MOOC videos together. The study was conducted with on-campus flipped classroom students. Our subjects reported an overall high satisfaction with the study group style. The research reveals that students like to stay synchronized in the group while watching MOOC videos. However, they have to find a balance between synchronization, video interaction, and the amount of conversation. Watching MOOCs on a shared display addresses the need of synchronicity, and the distribution of control can increase the video interactivities.  相似文献

The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals. Here we report on a study in which teachers, as part of their professional development, were involved in defining the term ‘chemical literacy’; they discussed the need for it, and suggested educational experiences that are necessary in order to attain it. The programme was conducted as part of a reform in the content, as well as in the pedagogy, of chemistry education in Israel. The collected data provide some insights regarding the process by which the teachers’ perception of ‘chemical literacy’ developed and the way actual school practice influences teachers’ perception of ‘chemical literacy’.  相似文献

Adult literacy education and development in Thailand: an historical analysis of policies and programmes from the 1930s to the present     

Pierre Walter 《International Journal of Lifelong Education》2013,32(2):79-98

This study of adult literacy education in Thailand analyses the ways in which the Thai state has historically shaped adult literacy education policies for development. For the authoritarian Thai state of the 1940s and 1950s, literacy education was a means of promoting nationalism through an imagined community of Thai citizens. For the developmentalist state of the 1960s, 1970s and 1980s, literacy education was the means to create a new Thai working class for industrial capitalism and export-oriented growth. For the liberal democratic state of the 1990s, literacy education was re-oriented toward a post-Fordist economy. Most recently, in the wake of the 1997 economic crisis and subsequent IMF and ADB ‘structural adjustment’ policies, state educational policies have shifted to an emphasis on fiscal economics over education. While state ideologies of educational policy are dominant in this historical narrative, they also possess internal contradictions contested by popular movements and social groups outside dominant classes. Literacy education in Thailand is, as such, not only the site of production and reproduction of state ideologies, but also of struggles over their meaning. Thus we find within the authoritarian nationalism of the 1940s and 1950s, a movement for popular democracy through literacy education born of the 1932 Revolution; within the work-oriented literacy programs of the 1970s, a trend towards broader community development inspired by the student revolution of October 1973; and within the neoliberal Thai state's embrace of globalization, a call for further democratization of educational opportunities first promoted by the May 1992 uprising and then embodied in the new Constitution of 1997 and the Education Act of 1999.  相似文献
