Response Conversion for improving comparability of International Physical Activity data.
BACKGROUND Many questionnaires for measuring physical activity (PA) exist. This complicates the comparison of outcomes. METHODS In 8 European countries, PA was measured in random samples of 600 persons, using the IPAQ as a 'bridge' to historical sets of country-specific questions. We assume that a unidimensional scale of PA ability exists on which items and respondents can be placed, irrespec...
متن کاملImproving Comparability of Existing Data by Response Conversion
Incomparability of information is the key problem in international comparisons. The usual way to improve comparability is to harmonise data collection efforts. However, harmonisation fails if the data have already been sampled, or if appropriate harmonisation cannot be achieved for whatever reason. This normally leaves no other option than to either make strong unwarranted assumptions about the...

Towards a methodology for improving the comparability of accelerometer-based results for physical activity measurements in older adults
Introduction: Accelerometry has become an established method for objective physical activity (PA) measurements in medical and epidemiological research. However, current accelerometer types record PA in proprietary, manufacturer-dependent representations called “activity counts”. Studies comparing these outputs or PA classification differences caused by varying positions or applied device-types ...
متن کاملA Survey of Dynamic Replication Strategies for Improving Response Time in Data Grid Environment
Large-scale data management is a critical problem in a distributed system such as cloud,P2P system, World Wide Web (WWW), and Data Grid. One of the effective solutions is data replicationtechnique, which efficiently reduces the cost of communication and improves the data reliability andresponse time. Various replication methods can be proposed depending on when, where, and howreplicas are gener...
