This paper presents the results of new stable isotopes (carbon and nitrogen) analysis of human, faunal and fish remains from thirteen cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results are integrated with earlier analyses, undertaken solely on human samples, in order to provide a comprehensive overview of subsistence across the Upper Palaeolithic through to Eneolithic periods in this region. This is the first time that a combined sample of human, faunal and fish remains has been studied in order to interpret subsistence strategies across these periods in Ukraine. The total dataset comprises 113 samples of human, faunal and fish remains, 59 of which include new analyses of faunal and fish remains that have not previously been made available for study (Table 1). The analysis of the faunal and fish remains allows for a consideration of trophic levels which indicates that the consumption of freshwater fish occurs from the Epipalaeolithic period onwards. Whilst the majority of the cemeteries and the individuals therein cluster in relatively tight groups, there is a significant offset between the human and faunal samples due to the consumption of freshwater resources. The fish samples analysed in the study appear to exhibit a relatively random distribution when compared to the other samples analysed. In general, freshwater resources remain significant through until the end of the Neolithic period and into the Eneolithic period at the sites investigated.  相似文献

This research examines the evidence for prehistoric ceramic exchange networks over the last 2000 years in northwest Alaska through the use of neutron activation analysis of ceramic artifacts. Results from ceramic analysis on eight coastal and inland archaeological sites identified three source macrogroups and three associated subgroups. Clay source diversity and shared source macrogroups between geographically distant sites suggest the use of multiple sources and/or the movement of pots between production locales, mirroring related patterns in pottery stylistic data. Although additional analytical work is needed to fully understand the changing character of clay procurement and ceramic distribution across this time period, this study provides exploratory data on past ceramic production and distribution that hints at changes in exchange and territoriality in northwest Alaska during the late Holocene.  相似文献

Abstract

An early nineteenth-century pink silk crepe gown adorned with thousands of faux pearls was one of the highlights of the Los Angeles County Museum of Art’s Autumn 2010 exhibit Fashioning Fashion. During conservation treatment, the faux pearls were examined in detail in order to inform conservation decision-making and a curious manufacturing method was found, namely a practice developed in the seventeenth century by a French rosary maker: delicate and hollow glass beads were filled with a slurry of material derived from fish scales and gelatin or sturgeon glue. This information supported treatment decisions for the piece and is shared here to disseminate information on the history and manufacture of faux pearls and to inform collections care approaches for costume decorated with these extraordinary and fragile beads. This approach demonstrates how detailed examination of an object can act as the catalyst for exploring the history of manufacturing technology as well as deepening understanding of dress history.  相似文献

Drawing upon documentary sources and interviews with administrative officials, this article takes a broad look at presidential management of the bureaucracy during the Johnson presidency. The various managerial techniques used by President Johnson are examined, along with some of the purposes of presidential management. Contrary to the historical stereotype, Johnson was a managerial activist who had a substantial impact on the bureaucracy and “permeated” it by his many actions  相似文献
