This study presents a provenance analysis of the Neolithic obsidian assemblages from the early to mid-sixth millennium bc settlement at Göytepe, Azerbaijan. The study is unique in that (1) it involves a complete, non-selected obsidian assemblage (901 artefacts) from one particular area of the site; (2) the material is derived from a well-stratified sequence of 10 securely radiocarbon-dated architectural levels; and (3) the use of an extraordinarily wide range of sources (more than 20) was identified by provenance analysis using energy-dispersive X-ray fluorescence. The results reveal a previously unknown diachronic change in obsidian use in the region, suggesting the occurrence of significant socioeconomic changes during the Late Neolithic of the southern Caucasus.

This article is a summary of information provided by the author to Hiroshima University and two other universities in Japan during his visit in December, 2011. The content is based on a multidimensional model of stuttering that accounts for cognitive, affective, linguistic, motor, and social (CALMS) factors that contribute to the maintenance of stuttering in school-age children who stutter. This article describes the CALMS model and how it serves as the basis for the 23 items used in the CALMS Assessment of stuttering. Specific items used in the CALMS Assessment are listed along with the rationale for assessing each item. Once the assessment data are obtained, a profile of performance across the 23 items can be created. From the profile, a clinician can focus on specific items across the CALMS domains that need to be addressed in treatment. Specific treatment suggestions for children who stutter are described.
