This study examined the effects of the rider on the linear projectile kinematics of show-jumping horses. SVHS video recordings (50 Hz) of eight horses jumping a vertical fence 1 m high were used for the study. Horses jumped the fence under two conditions: loose (no rider or tack) and ridden. Recordings were digitised using Peak Motus. After digitising the sequences, each rider's digitised data were removed from the ridden horse data so that three conditions were examined: loose, ridden (including the rider's data) and riderless (rider's data removed). Repeated measures ANOVA revealed significant differences between ridden and loose conditions for CG height at take-off (p < 0.001), CG distance to the fence at take-off (p = 0.001), maximum CG during the suspension phase (p < 0.001), CG position over the centre of the fence (p < 0.001), CG height at landing (p < 0.001), and vertical velocity at take-off (p < 0.001). The results indicated that the rider's effect on jumping horses was primarily due to behavioural changes in the horses motion (resulting from the rider's instruction), rather than inertial effects (due to the positioning of the rider on the horse). These findings have implications for the coaching of riders and horses. 相似文献

BACKGROUND: This article is the second part of a two-part series reporting a study of the role of the Clinical Librarian (CL) in the UK. METHODS: A qualitative method of semi-structured interviews was used to explore in-depth the role of the CL. The interviews provided a rich source of data and give insight into this new and emerging role as practised in the National Health Service (NHS). Similarities and differences are examined between the CL population and reported within themes, specifically: personal qualities and skills required, training for the CLs, marketing the CL service, working in the clinical environment, monitoring and evaluation and the acceptance of the CL in the NHS. RESULTS: A common understanding of the skills and knowledge required to undertake the CL role was shared by the respondents. However, practice differed as this was often dictated by local circumstances. The study confirmed the need for the CLs to work with clinical colleagues in the clinical setting to enhance patient care. CONCLUSION: The importance of using best evidence to support patient care is a message that is slowly becoming the norm in the NHS and the CL role in this practice is demonstrated by this study. 相似文献

This study examined the effects of a multicomponent social communication intervention to promote language learning and peer‐directed social interactions in preschool children with disabilities. Participants were eight children with developmental disabilities who met the specified criteria for the study. The intervention consisted of three components: (a) a planning period for instructional purposes, (b) a play session to practice skills, and (c) a brief reporting period to review skill performance. A multiple baseline design across two dyads replicated across two additional dyads was used. Results indicated an increase in peer‐directed requests, verbal requests, and word diversity for 6 of the 8 participants postintervention. Implications of the results are discussed. © 2008 Wiley Periodicals, Inc. 相似文献

This editorial introduction frames the special issue by highlighting its choices: examining transitions in the educational
process, so as to highlight common features of many educational phenomena, often considered separately; and conceptualise
transitions as time-embedded processes. Such theoretical choices raise methodological questions, among which, that of preserving
the dynamics of education. Three main methodological options for doing so are considered: time reconstruction (verbal or graphic);
real-time data gathering; and focus on the individual-social articulation. Each of the papers is thus presented through its
specific methodological choices. Finally, two transversal characteristics of transitions are highlighted: the person-and-environment
mutual responsiveness, and their inherent playfulness; some consequences for education are suggested. 相似文献

There are few studies that have directly examined teachers’ perceptions of children with ADHD, particularly children in the adolescent age range. The purpose of this study was to examine the perceptions of general‐education ninth through twelfth grade teachers regarding working with adolescent students with ADHD. Sorted responses from a sample of 100 general‐education high school teachers were analysed and then represented visually using a concept‐mapping technique. The final concept map suggests that teachers perceive adolescents with ADHD along two dichotomies of thematic clusters on an orthogonal axis. Clusters at the top area of the concept map suggest perceptions related to high confidence and willingness, while clusters at the bottom suggest perceptions related to uneasiness and frustration. Clusters along the left side of the concept map suggest perceptions related to behaviour issues, while clusters along the right side suggest perceptions related to classroom teaching issues. Central to the vertical and horizontal dichotomies is a solitary central dimension, which highlights training as an important component of teachers’ perceptions of adolescents with ADHD. 相似文献

The industrial and occupational distribution of women is such that women are concentrated predominately in a few occupations, mostly in the service sector, such as banking, finance, insurance, public administration, hotel, and catering. Men and women are equal in their capabilities in almost every respect, provided that women are given the same opportunities as men for training, employment, and promotion. There is a lack of research studies on women in the construction industry; therefore this field needs special consideration. The purpose of the current study is to find out working conditions of the Palestinian women civil and architect engineers in the construction industry in the Gaza Strip, Palestine. In addition, it attempts to examine their career prospects and to understand problems experienced by these women throughout their academic years as well as in their careers. Discrimination against women is still present in today's construction industry as well as in other traditional engineering cultures. In order to minimise or cope with this problem, attitudinal change by both men and women is strongly suggested. 相似文献
