Research examining our ability to avoid obstacles in our path has stressed the importance of visual input. The aim of this study was to determine if athletes playing varsity-level field sports, who rely on visual input to guide motor behaviour, are more able to guide their foot over obstacles compared to recreational individuals. While wearing kinematic markers, eight varsity athletes and eight age-matched controls (aged 18–25) walked along a walkway and stepped over stationary obstacles (180° motion arc). Visual input was manipulated using PLATO visual goggles three or two steps pre-obstacle crossing and compared to trials where vision was given throughout. A main effect between groups for peak trail toe elevation was shown with greater values generated by the controls for all crossing conditions during full vision trials only. This may be interpreted as athletes not perceiving this obstacle as an increased threat to their postural stability. Collectively, findings suggest the athletic group is able to transfer their abilities to non-specific conditions during full vision trials; however, varsity-level athletes were equally reliant on visual cues for these visually guided stepping tasks as their performance was similar to the controls when vision is removed. 相似文献

Purpose
The study evaluates how providers give patient education materials and identifies improvements to comply with Meaningful Use (MU) requirements.Methods
Thirty-eight patient-provider interactions in two health care outpatient clinics were observed.Results
Providers do not uniformly know MU patient education requirements. Providers have individual preferences and find gaps in what is available. Accessing and documenting patient education varies among providers. Embedded electronic health record (EHR) materials, while available, have technical access barriers.Conclusions
Providers'' EHR skills and knowledge levels contribute to non-standardized patient education delivery. 相似文献94.

Alternating Current (AC) is used all over the world today. In India we use AC at 50 Hz (cycles per second) and in USA and
Canada at 60 Hz. During the latter part of the 19th century, even during the early part of the 20th century, Direct Current
or DC was widely used. Had we continued with DC, electricity would not have been as widely available as it is today and its
use would have been cumbersome, costly and severely restricted. We owe it mainly to the Serbian genius Nikola Tesla that electricity
has reached almost every nook and corner of most continents. 相似文献

A large scale modularisation of curricula in higher education based on relatively large modules is discussed. These modules are flexible courses and not the well known small instructional modules within a course. The idea of these so-called programme modules, together with some applications and implications are discussed in the context of the Dutch higher educational system which is quite similar to that in other Western European countries. One implication is a less static concept of what a curriculum is. This may affect students, teachers, curriculum planners and legislators in their thinking about what kind of education a university can offer (in the near future) to its potential clients. 相似文献

This review examines Psychology and the Study of Education: Critical Perspectives on Developing Theories, a collection of academic articles edited by Cathal Ó Siochrú. The collection comprehensively considers wide-ranging topics pertinent to the psychology of education, with a target audience of educators and students wishing to learn more about psychology. The review evaluates the collection as an integrated work of entries and analyses each component chapter; recognising the success of the collection with respect to its aim of challenging readers to critically reflect upon and consider the value of psychology in both understanding and influencing education. The book transcends the common formula of academic article collections in this area by being presented in a somewhat conversational manner, making it both interesting and accessible. The book is recommended for anyone interested in the psychology of education and for anyone who values the advancement of learning and teaching. 相似文献
