Cultural dynamics and ceramic resource use at Late Bronze Age/Early Iron Age Troy,northwestern Turkey

Changes in resource use over time can provide insight into technological choice and the extent of long-term stability in cultural practices. In this paper we re-evaluate the evidence for a marked demographic shift at the inception of the Early Iron Age at Troy by applying a robust macroscale analysis of changing ceramic resource use over the Late Bronze and Iron Age. We use a combination of new and legacy analytical datasets (NAA and XRF), from excavated ceramics, to evaluate the potential compositional range of local resources (based on comparisons with sediments from within a 10 km site radius). Results show a clear distinction between sediment-defined local and non-local ceramic compositional groups. Two discrete local ceramic resources have been previously identified and we confirm a third local resource for a major class of EIA handmade wares and cooking pots. This third source appears to derive from a residual resource on the Troy peninsula (rather than adjacent alluvial valleys). The presence of a group of large and heavy pithoi among the non-local groups raises questions about their regional or maritime origin.     

Effect of Infill Walls on the Drift Behavior of Reinforced Concrete Frames Subjected to Lateral-Load Reversals

Four-story, single-bay, 1/5 scaled reinforced concrete frames were tested with and without infill walls. Frames were subjected to pseudo-static cyclic loading. In addition, impact hammer measurements were made to obtain the natural frequencies and modal shapes at certain drift levels. It was observed that infill walls cause major changes on both the stiffness and the drift behavior of the frames. Effect of observed changes can be either advantageous or disadvantageous depending on failure mode. Results showed that the distribution of drift that is based on the mode shapes has higher local concentrations than the distribution observed under forced static conditions.     

Is there Really Divergence Across Turkish Provinces? Evidence From the Lagrange Multiplier Unit Root Tests

Using data on per capita income among 67 provinces in Turkey over the period 1975–2001, regional stochastic convergence is evaluated. This study employees the LM unit root test to endogenously determine the number and location of structural breaks for each province. On the contrary, convergence literature on Turkish provinces, both univariate and panel LM tests provide strong evidence for convergence except for the provinces of Bitlis and Erzurum when structural breaks are taken into account. Our empirical results are in accordance with the neoclassical model.     

The Early Iron Age at Troy Reconsidered

Neutron Activation Analysis (NAA) of Protogeometric ceramics at Troy supports a revision of our understanding of the site in the Protogeometric period. Previous interpretations of this period at Troy emphasized the importance of either Greek migration or Greek trade networks. A category of amphoras previously thought to be imports appears to have been made locally. NAA also indicates local production of a new class of handmade cooking pots, as well as more traditional Gray ware vessels. Analysis reveals a high degree of cultural continuity at Iron Age Troy, with inhabitants adopting and adapting a wider vocabulary of Protogeometric vessel types in the Aegean while integrating them with established local pottery traditions and resource use. The combinations of local and non‐local components seen at Troy are more consistent with long‐term dynamic Aegean interaction spheres than with more tenuous models of Aeolian migration or Euboian expansion.
