چکیده
1. the decomposition of obtained scores into true and error components (20, 32, 66, 81, 90); 2. the duality of psychophysics and psychometrics (16, 72, 73, 88, 91); 3. the notion of unidimensionality (33, 34, 51, 68); 4. the conception of test validity as theoretical equivalence, usually called construct validity (21); 5. the scaling ideas derived from various item characteristic curve models (3, 4, 54, 75, 91, 93).

Understanding DO-254 Compliance for the Verification of Airborne Digital Hardware
Anthony D. Stone Synopsys, Inc Abstract This whitepaper is designed to provide a basic understanding of the main concepts of the DO-254 compliance specification for electronic component design. It outlines the major steps involved in a DO-254 compliant ASIC/FPGA design and verification process, and explains how differentiating tool features can be mapped to enhance and facilitate critical stage...
متن کاملA Preliminary Parasitological Survey of Hepatozoon Spp. Infection in Dogs in Mashhad, Iran
BACKGROUND We attempted to determine the prevalence of Hepatozoon spp. infection in Mashhad, northeast of Iran, via blood smear parasitology. METHODS The prevalence was investigated by examination of blood smear parasitology, using blood samples collected from 254 dogs (51 strays and 203 privately owned-dogs). RESULTS Two stray dogs (2/51; 3.92%) and two privately-owned dogs (2/203; 0.98%) ...
متن کاملChemosensitivity testing of a novel platinum analog, nedaplatin (254-S), in human gynecological carcinomas: a comparison with cisplatin.
BACKGROUND The tetrazolium dye (MTT) assay is useful for predicting chemosensitivity. MATERIALS AND METHODS Using the MTT assay, an in vitro chemosensitivity test was designed for nedaplatin (cis-diammine glycolato platinum; 254-S) and the results were compared with the sensitivity to cisplatin in 137 resected gynecological carcinomas. RESULTS The mean tumor inhibition rate [I.R.; %] for ne...
متن کاملThe development of enhanced information retrieval strategies in undergraduates through the application of learning theory: an experimental study
In this paper, I describe an experimental study on the efficacy of concept-based instruction in developing information retrieval skills in undergraduates. The subjects were 254 first-year undergraduates at the University of Canberra, Australia. The study followed the experimental design of a pre-test/post-test control group. The experimental group was taught information retrieval from electroni...
