This research demonstrates that Dual Scaling (DS) is a valuable tool for optimally scaling ordinal variables in the calculation of correlation matrices for analysis in structural equation modelling (SEM). More specifically, it shows that there are circumstances where correlation estimates based on DS would be a more appropriate choice for use in SEM than the Pearson product moment, canonical, or polychoric correlation techniques. With respect to ordinal variables, the study demonstrates that the SEM application of canonical correlation is unacceptable, that the Pearson correlation generates...

This volume presents a functional and typological study of the Iron Age artefacts recovered during six years of excavation at the site of Tall Jawa, in central Jordan.
The introduction presents information on the recording and classification system used to identify artefact types. The main chapter presents each category of artefact with examples of the most representative items, and their parallels from sites in Israel and Syria. Examples include jewellery, figurines, weapons, food processing tools, and tools used in a variety of crafts and industries. A CD-ROM is included, containing the...
