The aims of this study were to: (1) determine whether the number of pedometer counts recorded by adolescents differs according to the adiposity of the participant or location on the body; (2) assess the accuracy and reliability of pedometers during field activity; and (3) set adolescent pedometer-based physical activity targets. Seventy-eight 11- to 15-year-old Boy Scouts completed three types of activity: walking, fast walking and running. Each type was performed twice. Participants wore three pedometers and one activity monitor during all activities. Participants were divided into groups of normal weight (BMI < 85th percentile) and at risk of being overweight (BMI > or = 85th percentile). Intra-class correlations across the three activities indicated reliability (r = 0.51 - 0.92, P < 0.001). This conclusion was supported by narrow limits of agreement that were within a pre-set range that was practically meaningful. Multivariate analysis of covariance indicated adiposity group differences, but this difference was a function of the increased stature among the larger participants (P < 0.001). Ordinary least-squares regression models and multi-level regression models showed positive associations between the number of pedometer and activity monitor counts recorded by the three groups of participants during all activities (all P < 0.001). The mean number of counts recorded for all participants during the fast walk was 127 counts per minute. In conclusion, the pedometers provided an accurate assessment of adolescent physical activity, and a conservative estimate of 8000 pedometer counts in 60 min is equivalent to 60 min of moderate to vigorous physical activity. 相似文献

Telematics has the potential to transform Higher Education through creating a distributed community of tutors and students. Videotutoring is central to telematics, enabling personal tutoring to occur at a distance. Within the context of a post-graduate teacher training course, videotutoring was used to tutor two students during the first six weeks of their first full-time school placement. Both ends of the videosignal were recorded. Analysis of the tapes used a protocol based upon research into non-verbal communication (NVC). NVC is as important as verbal communication in the tutorial process. Findings suggest that the interaction of participants mediated through the screen was significantly different from face-to-face communication in relation to the two-dimensional image of the screen and the "viewing frame" effect of the physical boundaries of the image. The viewing frame literally served as the proscenium arch of a theatre. Two-dimensionality and the viewing frame effect emphasised both the positive and negative elements in inter-personal communication as represented in Argyle's social skills and Goffman's theatrical models. The conclusion is that videotutoring can potentially be a more effective form of tutoring than face-to-face interaction. 相似文献

There is a lack of systematic research on the training of clinicians toward providing counselling services and support to individuals with Fetal Alcohol Spectrum Disorder (FASD). The aim of this qualitative project was twofold: (1) to develop and pilot a clinical consultation process that would address clinicians’ reported need for greater communication and information sharing in serving clients affected by FASD; and (2) to build a model of FASD-informed clinical counselling practice by examining this consultation process and by capturing the experiences of clinicians who were involved. Findings from focus groups and meeting minutes are reported with respect to the model’s focus on reflection, communication, and action. 相似文献

This single-subject, experimental research design examined the efficacy of treating severe, long-term selective mutism in a 9-year-old male using shaping, multiple re-inforcers, natural consequences, stimulus fading, and mild aversives. Different treatment regimens were implemented in the home and school environments. A multiple baseline design across settings with changing criterion was used to evaluate the home intervention, and an A-B-A design was used for the school intervention. The home intervention resulted in an increase in the number of verbalizations in each setting and prompted generalization to additional settings. The school intervention increased the number of people spoken to, but the results were not maintained at follow-up nor did they generalize outside of the training situation. Possible explanations for the discrepancy in maintenance and generalization data between the two programs are presented. 相似文献

As counselor preparation programs are compelled to demonstrate student social and cultural competence, valid inventories are needed to measure development consistent with contemporary standards. The Intersectional Privilege Screening Inventory was created for this purpose, was assessed using 4 types of validity evidence, and has results supporting its use in student development. 相似文献
