This paper quantitatively evaluates the mutually compensatory property in audio–video transmission over the Internet by the psychometric method. In our previous study, we used MOS (Mean Opinion Score) as the user–level QoS parameter; however, MOS is an ordinal scale, and therefore, its value does not necessarily represent exact difference between the observer’s sensory magnitude. In order to so...

screened for appropriateness for one or more of the following criteria; describing tool development; detailing instructions for use of the tool; or reporting at least one psychometric property. Full text articles were obtained for all psychometric studies.

We set up a label-free direct binding assay for the detection of noncoding RNAs. The assay is based on nanomechanical cantilever arrays for the detection of surface stress induced by immobilized biomolecules and their interaction partners. We used various means to significantly reduce the drift of the cantilever readout that was a prominent feature in experiments with readout in stationary flui...

We show how to combine program slicing and constraint solving in order to obtain better slice accuracy. The method is used in the VALSOFT slicing system. One particular application is the validation of computer-controlled measurement systems. VALSOFT will be used by the Physikalisch-Technische Bundesanstalt for verification of legally required calibration standards. The article describes the VA...

Over the last decades, trust in physician has gained in importance. Studies have shown that trust in physician is associated with positive health behaviors in patients.

The present study aims to test the psychometric property of scale obtain sound instrument. procedure this included construction, followed by identification covering content validity (using Aiken’s V and reliability (Cronbach’s Alpha) data obtained from 203 respondents. coefficient final w...

OBJECTIVE To conduct a systematic review using validated critical appraisal scales to analyze both the quality and content of the psychometric evidence of spasticity measurement tools in cerebral palsy children and adolescents. DATA SOURCES The literature search was performed in 3 databases (Pubmed, CINAHL, Embase) up to March 2012. STUDY SELECTION To be retained for detailed review, studie...
