Some job tasks do not lend themselves to formal on-the-job assessment because they do not occur with sufficient regularity to permit the standardized measurement required in validational research. The preparation of incident reports by police and security officers is such a job task. The production of accurate, literate incident reports is important because these reports are often required in l...

PURPOSE To compare the conspicuity of malignant lesions between FDG PET/CT and a new simultaneous, time-of-flight (TOF) enabled PET/MRI scanner. METHODS All patients underwent a single-injection of FDG, followed by a dual imaging protocol consisting of PET/CT followed by TOF PET/MRI. PET/CT and PET/MRI images were evaluated by two readers independently for areas of FDG uptake compatible with ...

It has been demonstrated that social exclusion, or ostracism, results in a decrease in four fundamental human needs: belonging, control, self-esteem, and meaningful existence. We replicated these results, and examined how empathizing and systemizing cognitive styles accounts for variation in the experience of social exclusion (self-reported distress and the four fundamental needs) during an int...

Test score distributions of schools or demographic groups are often summarized by frequencies of students scoring in a small number of ordered proficiency categories. We show that heteroskedastic ordered probit (HETOP) models can be used to estimate means and standard deviations of multiple groups’ test score distributions from such data. Because the scale of HETOP estimates is indeterminate up...

Lactational means of somatic cell score from sample days of primiparous DHI cows were analyzed to compare dairy records processing centers for data properties, to examine effects of age at calving and month of calving on somatic cell score, and to calculate preliminary PTA of sires for somatic cell scores. Five processing centers contributed data but differed substantially with respect to avail...

The purpose of this study was to combine a standardized visually based system, the International Caries Detection and Assessment System (ICDAS), with a sensitive fluorescence-based system, quantitative light-induced fluorescence (QLF), to determine the ability to monitor caries lesion progression. This combination (QLF-I) has the potential to increase the sensitivity of the visual method withou...
