Students who completed a Child Development course (N = 1168) from 3 to 16 years prior to retention testing were tested for recognition and recall of facts and application of mental skills. Students who subsequently served as course tutors were also tested for retention. Fact retention was superior to application retention and retention for both question types declined rapidly from year 3 to year 7 after which it stabilized. Recognition items were superior to recall items for high achieving students only. Tutors retained more than non-tutors for eight years after which there were no differences. 相似文献

Ground reaction force measurements are a fundamental element of kinetic analyses of locomotion, yet they are traditionally constrained to laboratory settings or stationary frames. This study assessed the validity and reliability of a new wireless in-shoe system (Novel Loadsol/Pedoped) for field-based ground reaction force measurement in hopping, walking, and running. Twenty participants bilaterally hopped on a force plate and walked (5 km/hr) and ran (10 km/hr) on an instrumented treadmill on two separate days while wearing the insoles. GRFs were recorded simultaneously on each respective system. Peak GRF in hopping and peak GRF, contact time (CT), and impulse (IMP) in walking and running were compared on a per-hop and step-by-step basis. In hopping, the insoles demonstrated excellent agreement with the force plate (ICC: 0.96). In walking and running, the insoles demonstrated good-to-excellent agreement with the treadmill across all measures (ICCs: 0.88–0.96) and were reliable across sessions (ICCs within 0.00–0.03). A separate verification study with ten participants was conducted to assess a correction algorithm for further agreement improvement but demonstrated little meaningful change in systemic agreements. These results indicated that the Novel Loadsol system is a valid and reliable tool for wireless ground reaction force measurement in hopping, walking, and running. 相似文献

For decades, debates over medical curriculum reform have centred on the role of science in medical education, but the meaning
of ‘science’ in this domain is vague and the persistence of the debate has not been explained. Following Bourdieu, this paper
examines struggles over legitimate knowledge and the forms of capital associated with science in contemporary UK medical education.
Data are presented from a study of two UK medical schools, one with a traditional, science-oriented curriculum, another with
an integrated curriculum. Constructions of legitimate knowledge were explored at both schools through six months participant
observation, interviews with faculty members (n=15) and students (n=37) and documentary analysis. Findings show that medical
schools compete for both scientific and clinical capital, but ultimately science has greater legitimacy. ‘Science’ is defined
in accordance with the structure of the traditional curriculum and has become a symbolic resource – a mark of distinction
for both medical schools and medical students – which is equated with clinical competence. The significance of science is
circumscribed by the medical education field, yet the struggles for scientific capital there have ramifications beyond medical
education itself. It is argued that Bourdieu’s concepts are particularly useful tools for studying the meanings that science
takes on outside of the scientific field. 相似文献

The paper examines Pierre Bourdieu’s extensive writings on the production of scientific knowledge. The study shows that Bourdieu
offered not one but two - significantly different - approaches to scientific knowledge production, one formulated in his theoretical,
or programmatic, writings on the subject, the other developed in his empirical writings. Addressing the question as to the
relevance of Bourdieu’s work for science studies, the analysis argues that the former of these two approaches is at once very
visible in Bourdieu’s work but characterized by limitations from the standpoint of scholarship in STS, whereas the latter
approach is less conspicuous but of broader empirical value. 相似文献

Top short track speed skaters and their coaches have suspected that starting positions influence finishing positions, especially in the 500 m racing distance. The objective of this study was to examine systematically the influence of starting position on finishing position in 500 m short track speed skating. The data analysed included results from World Cup 500 m races ranging from the 1999-2000 season through to the end of the 2003-2004 season. All 500 m men's and women's races with four skaters starting and finishing (preliminaries, heats, quarter-finals, semi-finals and finals) were included in the data set. The association between starting position and finishing position was examined using Kendall's tau. Results show that for both sexes, there is a significant positive correlation between starting position and finishing position (P<0.001). This effect is generally more pronounced in semi-finals and finals than it is in preliminaries, heats and quarter-finals. Strategies to counter this inequity are proposed, drawing upon similar experiences in other sports. 相似文献

The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), HAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults. 相似文献

A definition of dyslexia 总被引:17,自引:0,他引:17
This paper elaborates on the components of a working definition of developmental dyslexia. It follows the general format of
a paper by Lyon published in Annals of Dyslexia in 1995, which elaborated on a working definition proposed in 1994 (Lyon,
1995). The current definition agreed on by the work group updates and expands on the working definition from 1994. 相似文献
