This study involves the high-resolution spatial analysis of a 9,500-year-old Early Neolithic site in an effort to reconstruct the social and economic organization of the settlement at household and community scales. We introduce an approach to distinguishing stratified occupational surfaces (floors) from intervening deposits (fills), to tracing the different formation processes associated with floors and fills, and to critically examining various factors (curation behaviors, palimpsests, and the Clarke Effect) that may have shaped house floor assemblages. The spatial analyses of behavioral residuals, features, and structures are then presented at intramural and intrasite scales, and the results are discussed as they relate to certain aspects of the social and economic organization of the community. These include family structure, control of resources, social differentiation, ritual participation, craft specialization, and gender-linked activities.

The ANTIQUITY paper by Neeley & Barton (1994) — hereafter ‘N&B'— prompted responses published in the June number last year: Fellner (1995) and Kaufman (1995). Here are more (all shorter than the full versions received), together with a response from Barton & Neeley (B&N) that rounds off the present discussion. The debaters have seen others’ contributions, so there is some cross-comment within them. The questions and the issues are old fundamentals of lithic research and analsis, which one cannot expect to end with this debate.

The relationship between raw material availability, economizing behaviours and technological procedures undoubtedly influenced the configurations of Levantine Epipalaeolithic assemblages, as has been well recognized for over 20 years (Bar-Yosef 1970; Henry 1973). Other 'functional factors' have also been examined — environmental settings, settlement mobility and provisioning strategies. While each factor has been shown to have influenced the specific configurations of Epipalaeolithic assemblages, none (other than broad environmental settings) has been shown to account for the large-scale patterned variability that distinguishes the three major taxa, the Geometric Kebaran, Natufian, and Mushabian complexes. This is why most prehistorians working in the region hold that ethnicity, at some scale, provides the most robust explanation for the patterned variability observed and for the temporal and geographic distributions at the taxonomic level of 'complex'.

Intercalative polymerization of aniline, pyrrole and 2,2’-bithiophene in vanadium oxide xerogels results in electrically conductive novel materials which are composed of alternating monolayers of metal-oxide and conductive polymers. The driving force for this intercalation is redox chemistry. The conductivity type in these materials is a function of the polymer/V2O5 xerogel ratio. Low ratios result in xerogel-based charge transport, while high ratios favor polymer-based charge transport properties. Chemical, spectroscopic and electrical data on the intercalative polymerization products of aniline, pyrrole and 2,2’-bithiophene with V2O5 xerogels are presented.
