BACKGROUND The "gold standard" for measuring gross motor function in children with cerebral palsy is the 66-item Gross Motor Function Measure (GMFM-66). OBJECTIVE The purpose of this study was to estimate the validity and reliability of 2 abbreviated versions of the GMFM-66; one version involves an item set approach, and the other version involves a basal and ceiling approach. DESIGN This w...

This paper develops and discusses a framework for the assessment of statistical quality in EU-SILC, with focus on comparability as a central dimension of quality. We view data quality as a multidimensional concept, covering not only statistical accuracy but also the relevance, timeliness, comprehensiveness, etc., of the data. There is a broad agreement on what dimensions make up the overall qua...

OBJECTIVES The main objective of this paper is to describe the approach and specific findings of the European Physical Activity Surveillance System (EUPASS) research project. In particular, the analysis presented aims at testing the reliability, comparability and predictive power of different sets of physical activity (PA) indicators. DESIGN First, a panel study based on computer-aided teleph...

Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...

As microprocessor-based systems grow in complexity, and the processor-memory speed gap widens further, more emphasis needs to be placed on early design space exploration in order to produce the highest performance systems with minimal schedule impact. We discuss the critical issues associated with architectural evaluation of complex microprocessor-based systems, and present a methodology for th...

conclusions surveys and opinion polls are valuable research tools and feedback mechanisms for administrative decisions; they should not be discredited by obtrusive questioning or asking for private information, with commercial or other purposes. context many studies on alcohol misuse and related topics such as the use of condoms are based on surveys. however, some surveys are not free from bias...

one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...
