Serial assessments of neurocognitive functioning in athletes with concussion are commonly used for return to play decisions. This study provides reliable change indices (RCIs) for computerized tests from 40 NCAA Division I collegiate athletes that suffered a sports-related concussion. The normative data that resulted from the RCIs and subsequent analyses of differences between improved and not ...

The reliability and validity of standard and qualitative scores for the Ruff Figural Fluency Test (RFFT; Ruff, 1988) was examined in 102 healthy undergraduates. Participants (M age = 21.79; SD = 3.7; age = 80% Caucasian) were administered the RFFT and measures assessing executive functions (EF) and other cognitive domains. Inter-scorer reliability was excellent (0.9 range) for most RFFT indices...

OBJECTIVE To compare the prognostic value of qualitative estimates of left ventricular function with that of routine simple quantitative indices used in echocardiography. DESIGN Retrospective follow up study. SETTING University hospital. PATIENTS The records of 2,964 patients who had undergone echocardiography and who could be traced on the family health services register were examined; 9...

A food web customarily describes the qualitative feeding relationships in a community. Descriptors have been used to extract ecologically meaningful information from such data, e.g., the proportion of top species (the proportion of taxa without consumers) or vulnerability (the average number of consumers per taxon). Analyses of collections of food webs based on these properties have revealed re...

AIMS Ebstein's anomaly (EA) is often associated with right ventricular (RV) dysfunction. Data on echocardiographic quantification of RV function are, however, rare. The aim of this study was to determine how non-volumetric echocardiographic indices and qualitative assessment of global systolic RV function correlate with cardiovascular magnetic resonance (CMR)-derived RV ejection fraction (EF). ...

As most data models, “Computing with words” uses a mix of methods to achieve its aims, including several measurement indices. In this paper we discuss some proposals for such indices in the context of rough set analysis and present some new ones. In the first part we investigate several classical approaches based on approximation quality and the drop of approximation quality when leaving out el...
