Audio Instruction tapes are described as a form of semi-automated learning whose potential previously has not been realized. Students do not listen to these tapes; they work along with them. These tapes are not lectures. They do not substitute for the teacher. They require the teacher and the class situation for enforcement of learning. This article describes the tapes available for applied statistics and explains how they are used. 相似文献

Abstract This article introduces the Partnership for Shared Book Collections, a federation of monograph shared print programs. Collaboration of programs at the network level allows for:
-
Reducing the cost of retaining the scholarly record through shared distribution of commitments;
-
De-duplicating efforts;
-
Developing and promoting evidence-based best practices;
-
Increasing the effectiveness of communication with end-users and funders;
-
Tackling large-scale projects and research that are out of reach for individual shared print programs. This shared stewardship of collection is critical as local resources are depleted due to the COVID-19 pandemic and access to print for digitization increases.

ABSTRACT Running is a common exercise with numerous health benefits. Vertical ground reaction force (vGRF) influences running injury risk and running performance. Measurement of vGRF during running is now primarily constrained to a laboratory setting. The purpose of this study was to evaluate a new approach to measuring vGRF during running. This approach can be used outside of the laboratory and involves running shoes instrumented with novel piezoresponsive sensors and a standard accelerometer. Thirty-one individuals ran at three different speeds on a force-instrumented treadmill while wearing the instrumented running shoes. vGRF was predicted using data collected from the instrumented shoes, and predicted vGRF were compared to vGRF measured via the treadmill. Per cent error of the resulting predictions varied depending upon the predicted vGRF characteristic. Per cent error was relatively low for predicted vGRF impulse (2–7%), active peak vGRF (3–7%), and ground contact time (3–6%), but relatively high for predicted vGRF load rates (22–29%). These errors should decrease with future iterations of the instrumented shoes and collection of additional data from a more diverse sample. The novel technology described herein might become a feasible way to collect large amounts of vGRF data outside of the traditional biomechanics laboratory. 相似文献
