The aim of the study was to determine the accuracy and variability of an electromagnetic device in measuring spinal kinematics on a traditional and replica rowing ergometer. Kinematic data collected from the 3-Space FastrakTM system using a Standard Concept II ergometer were compared with a replica ergometer that was in part, composed of non-ferrous materials (modified ergometer). The Fastrak's sensors were fixed to a wooden “spine” with known angles (as measured by an inclinometer). The mean inclinometer angle from four sensors (1 ± 0.2°) was significantly different than the mean angle recorded on the standard ergometer ( ? 5.4 ± 3.4°) (p = 0.007) whilst the angles recorded on the modified ergometer (1.4 ± 0.8°) were statistically equivalent to the inclinometer recordings (p = 0.660). These results indicate that the presence of ferrous material in a standard ergometer reduced the accuracy and increased the variability of data collected with the electromagnetic device. However, information collected on largely non-ferrous ergometers can provide coaches, biomechanists and clinicians with a quick and effective way to measure trunk kinematics during ergometer rowing. 相似文献

The quality of governmental websites is often measured with questionnaires that ask users for their opinions on various aspects of the website. This article presents the Website Evaluation Questionnaire (WEQ), which was specifically designed for the evaluation of governmental websites. The multidimensional structure of the WEQ was tested in a controlled laboratory setting and in an online real-life setting. In two studies we analyzed the underlying factor structure, the stability and reliability of this structure, and the sensitivity of the WEQ to quality differences between websites. The WEQ proved to be a valid and reliable instrument with seven clearly distinct dimensions. In the online setting higher correlations were found between the seven dimensions than in the laboratory setting, and the WEQ was less sensitive to differences between websites. Two possible explanations for this result are the divergent activities of online users on the website and the less attentive way in which these users filled out the questionnaire. We advise to relate online survey evaluations more strongly to the actual behavior of website users, for example, by including server log data in the analysis. 相似文献

The importance of experience and experiential learning is investigated in this report. An attempt is made to chart this concept and attention is paid to the manner in which experience can be measured and be used within the system of higher education. Since distance education attracts many mature adults with experiential learning, an indication is given of the direction that developments should take within Dutch higher education, and in the Open University in particular, in order to make an optimal use of this experience. 相似文献

ABSTRACTEarly Augmentative and Alternative Communication (AAC) interventions in school environments aim to support the development of the communication skills of children with complex communication needs. Goals of this study were to analyse the teachers’ attitudes towards children using AAC in primary schools in Italy and their perceptions of the barriers and the benefits of using AAC. Two groups of teachers, those with and without AAC experience, responded to an online survey. The five scales of the Teacher Attitude Scale (TAS) questionnaire and two open-ended questions were used to compare the attitudes and the perceptions between the groups of teachers. Results showed that there was a significant difference among the two groups for two of the five scales of the TAS questionnaire. Both groups reported similar barriers and benefits and indicated the use of AAC as being the main barrier. In conclusion, having experience with children who use AAC in class impacts the teachers’ perceptions of their own abilities and the teachers’ perceptions of the abilities of the children. 相似文献

This article is part of a study of the impact of higher education on aspects of the employment of a national sample of adult students (25 and over) who enrolled in higher education in Australia in 1978. The study shows that from the point of view of employment these adult students drew much benefit from their higher education. Females tended to benefit more than males. A further article in a later issue will consider for the same group the impact of higher education on the person. 相似文献
