Download or read book A Comparison Between the Vertical Scaling of Tests Sensitive to Multiple Dimensions Using Common item and Common group Designs written by Jing Yu and published by . This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three methods of item response theory (IRT) linking--common-item, common-group and a combination of common-item and common-group (referred to as common-common) linking designs were compared using real testing data from an English as second language (ESL) exam program. The methods were considered as "vertical scaling" instead of "equating" because, first, the test was designed to examine three different traits of English ability; multidimensional IRT and factor analysis on testing data confirms that the test was multidimensional. Second, the two test forms are not at the same difficulty level, the averaged difficulty parameters were different by about 0.5, 1.0 or 1.5 standard units, thus the linking was considered vertical. The effects of test length and averaged difficulty level differences were also analyzed. For practical reasons, the anchor test used in the common-item linking design could not represent all the dimensions of the test forms.

Download or read book Risk Assessment for Neurobehavioral Toxicity written by Bernard Weiss and published by DIANE Publishing. This book was released on 1997-07 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: After three decades of research, neurobehavioral toxicity is now acknowledged as a significant outcome of chemical exposure. Its health and economic costs may exceed those by cancer by substantial amounts. This new perspective has been accompanied by efforts designed to explore the responsible mechanisms, to design applicable risk assessment procedures, and to determine the consequent policy implications. This publication includes 25 papers from international experts and includes: human neurobehavioral toxicity; animal behavioral methods; selected model compounds; and risk assessment.
