Seasonality and paleodiet in the Chiribaya polity of southern Peru

In the Andes, the complex Chiribaya polity, or señorío, was composed of economically specialized groups. Previous carbon and nitrogen isotope analyses of archaeological human bone from Chiribaya-affiliated sites have effectively demonstrated socioeconomic specialization and variability in paleodiet among different Chiribaya-affiliated sites. The present study complements earlier paleodietary analyses of Chiribaya populations by supplementing them with carbon and nitrogen isotope analyses of archaeological human hair from the two Chiribaya-affiliated sites of Chiribaya Alta and El Yaral. These new data demonstrate that seasonal variability in the consumption of marine products and C₄ plants such as maize was quite high for some individuals buried at Chiribaya-affiliated sites. In addition to elucidating the complex patterns of Chiribaya seasonality, this study contributes to the growing body of knowledge of archaeological analyses of human hair for paleodiet.     

Problems in the interpretation of microscopic wear patterns: the evidence from bone skates

Microscopic examination of wear patterns on artifacts can produce valuable information on the manner in which they were made and used. In the case discussed here, observations made by an earlier worker are reaffirmed but a different interpretation is placed on their significance, so reconciling the scientific and historical evidence which were previously at variance.

THE LAW OF ONE PRICE IN A NETWORK: ARBITRAGE AND PRICE DYNAMICS IN NATURAL GAS CITY GATE MARKETS*

ABSTRACT. In this paper we develop a model of the law of one price in a network where many markets are linked with a structure of paths. We show that arbitrage-free prices depend on the structure of the network and so do price dynamics. Our estimates indicate that local bypass and open access pipeline transportation were instrumental in opening arbitrage paths to natural gas city markets and causing their prices to converge. Spot markets in the city gates, pipeline hubs, and production fields, that are scattered over distant points in the vast pipeline network in the United States, now form a single market.
