In this study, we examined the effects of number of years of playing rugby on neck function. Active cervical spine range of motion and proprioception were assessed in 14 non-rugby-playing but trained sportsmen (mean age 28 years, s = 7) and 46 rugby players (26 rugby forwards: mean age 26 years, s = 5; mean years played 14 years; 20 backs: mean age 24 years, s = 5; mean years played 14 years). Active cervical range of motion in flexion, extension, left and right lateral flexion, plus left and right rotation were measured using a cervical range of motion device. The ability to reposition the head in a central position with eyes closed was taken as a measure of proprioception. Results show that rugby forwards generally had the least active cervical range of motion, particularly neck extension (forwards, 43 degrees ; backs, 55 degrees ; controls, 58 degrees ), with the decrement correlating with the number of years played. In addition, repositioning was significantly worse in rugby players after neck extension than non-rugby players (6 degrees vs. 3 degrees ). The active cervical range of motion of rugby forwards is similar to that of whiplash patients, suggesting that participation in rugby can have an effect on neck range of motion that is equivalent to chronic disability. Reduced active cervical range of motion could also increase the likelihood of injury and exacerbate age-related neck problems. 相似文献

The initial observations of English teachers that computers have the potential to support collaboration, creativity, independent learning, subversion and reflection have been confirmed by fifteen years of work in the field, as have early concerns that computers could be used to direct inappropriate activities. Questions about the role of the teacher, the function of the computer, as well as the nature of pupils' learning when using IT, are now much better understood. Yet changes in the educational context within which English teachers are working, new understandings engendered by major curriculum projects and developments in the technologies themselves have brought about a shift in understanding of the significance of IT and its impact on the English curriculum. This paper shows how publications from the NATEMCET stable reflect the emergence of the field of English and IT. 相似文献

This article describes a working partnership between the Cairns Clinical Librarian Service, Health Care Libraries, University of Oxford and the Emergency Department (ED) at the John Radcliffe Hospital, Oxford. This collaboration resulted in the establishment of a guideline development group in June 2002. The aim of the group is to produce a set of easily accessible, user-orientated, evidence-based guidelines for the use of clinicians in the Emergency Department, within a realistic timescale. The Cairns Clinical Librarian Project was built on previous models of clinical librarianship and incorporated an evaluation of previous programmes. The objective was to provide information to clinicians at the time and point of need. Consultation with the ED from the outset determined the approach adopted by the Cairns team. Clinical guidelines have been shown to improve clinical practice. Pending the introduction of nationally available protocols, we have begun to establish a collection of evidence-based guidelines using web-based architecture in conjunction with the Oxford Radcliffe Hospitals NHS Trust's IT department. A piece of diagnostic analysis was undertaken to ensure a coherent strategy was developed for the guideline project. An 'intermediate approach' was adopted, where existing valid guidelines were modified to fit local circumstances. We strove to be transparent at all times about all aspects of the guideline development process. Formative evaluation has shown how the application of evidence-based health care needs adequate resources and requires people with appropriate knowledge and skills. This article charts the progress of the project and highlights how the partnership between the clinical team and the Clinical Librarian has been deemed to be essential to the success of the project. 相似文献

Understanding sustainability is important, as people need to cope with issues associated with over-population and over-consumption. Education is seen as a key strategy to assist with the development of people’s understandings of this complex concept, which could then lead to them being able to make more sustainable lifestyle decisions. In order to teach this concept, teachers need to understand sustainability. This paper investigated 77 New Zealand student teachers’ understandings of sustainability and the level of self-awareness of their understandings. A definition of sustainability was developed for this research from which two tools were constructed to measure these teachers’ level of understanding and self-awareness. Findings showed that many of these student teachers had simplistic understandings of sustainability that were focused on an environmental component. Further evidence of their low level of understanding was illustrated in the way that over half of this group were not able to accurately rate their own level of understanding. These findings suggest a need for the development of teachers’ understandings of sustainability so that they can plan and teach effective sustainability education programmes. 相似文献

The article examines the tensions one superintendent in the USA experienced as he evaluated principals in a high-stakes environment that had undergone numerous transformations at the central office. Using qualitative methods, primarily, shadowing techniques, observations and debriefing, the following tensions emerged and were examined in light of the work of the superintendent evaluating principal performance: (1) discrepancies between principal performance when compared to performance data, (2) length of time in the principalship compared to results, (3) finding the right balance between student achievement data and other indicators of principal performance, (4) what types of achievement data are important and when these data are made available, (5) credence paid to complaints about structural changes implemented by the principal, (6) balancing the principal self-evaluation rating scores with the final evaluator scores and (7) accounting for personal factors such as relationship to principals and knowledge about principal capabilities. Each of these tensions contributes to the difficulty a superintendent may feel when conducting the principal evaluation process. 相似文献
