The aim of our study was to determine if there is a role for manipulation of g force thresholds acquired via micro-technology for accurately detecting collisions in rugby union. In total, 36 players were recruited from an elite Guinness Pro12 rugby union team. Player movement profiles and collisions were acquired via individual global positioning system (GPS) micro-technology units. Players were assigned to a sub-category of positions in order to determine positional collision demands. The coding of collisions by micro-technology at g force thresholds between 2 and 5.5 g (0.5 g increments) was compared with collision coding by an expert video analyst using Bland–Altman assessments. The most appropriate g force threshold (smallest mean difference compared with video analyst coding) was lower for all forwards positions (2.5 g) than for all backs positions (3.5 g). The Bland–Altman 95% limits of agreement indicated that there may be a substantial over- or underestimation of collisions coded via GPS micro-technology when using expert video analyst coding as the reference comparator. The manipulation of the g force thresholds applied to data acquired by GPS micro-technology units based on incremental thresholds of 0.5 g does not provide a reliable tool for the accurate coding of collisions in rugby union. Future research should aim to investigate smaller g force threshold increments and determine the events that cause coding of false positives.  相似文献   

We're Listening: Using Patron Feedback to Assess and Enhance Purchase on Demand     

Uta Hussong-Christian  Kerri Goergen-Doll 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(5):319-335

Oregon State University Libraries piloted a one-year interlibrary loan purchase on demand service beginning in February 2009. An online survey was used to measure patron satisfaction and determine future borrowing and recommendation behavior. These results, along with patron comments, were used to explore future success of the service and ways to enhance the permanent service. Results provide context for the success of purchase-on-demand programs and support the development of innovative tools that increase the efficiency of purchase-on-demand workflow. Oregon State University Libraries permanently adopted the successful service and is working to incorporate patron input on purchase decisions.  相似文献

Quality in Early Childhood Education: An Anthropologist's Perspective   总被引：2，自引：0，他引：2  

Joseph Tobin 《Early education and development》2005,16(4):421-434

I use examples from my ethnographic work on early childhood education and care settings in Japan and France to demonstrate that quality standards are cultural constructs and to question the universality of such core U.S. standards of quality in ECEC as low student-teacher ratios and multicultural curricula. My argument is that quality standards should reflect local values and concerns and not be imposed across cultural divides. In a heterogeneous society such as the U.S., notions of quality should arise out of conversations in local communities among early childhood educators and parents.  相似文献
