Rice and millet were staple crops at Liangchengzhen, a late Neolithic Longshan site in Shandong, China, but the degree of dietary variation is not known. This study uses stable isotope analysis of human and faunal skeletal remains to quantitatively address the importance of these crops as well as terrestrial domesticates and aquatic resources in the diet at Liangchengzhen. Although no collagen could be extracted from the poorly preserved human bones, the δ13C stable isotope results for 2 apatite sample and 16 tooth enamel samples averaged −9.8‰ suggesting that diet was based on foods averaging from −24‰ to −18‰, with millet and millet-fed animals comprising at most approximately 25–30% of the diet. Pig faunal δ13C isotope values suggested that during the earlier Longshan period pigs were fed mainly millet with more C3 foods such as rice included by the later Longshan period. Solid ceramic residues from two guan jar sherds produced δ13C values averaging −18‰ and δ15N values averaging +16‰, suggesting both vessels contained fish. The results of the study indicate that by the Longshan period, people in southeastern Shandong no longer relied as heavily on millet and that the agricultural crop of rice had increased in importance at Liangchengzhen. Unfortunately, without human collagen samples to provide nitrogen isotope results, we cannot estimate the relative contribution of aquatic and terrestrial protein to the diet of people at Liangchengzhen. In general, however, the pattern of a diverse agricultural system on the basis of the macrobotanical remains from Liangchengzhen is supported by the isotopic results.  相似文献

Focusing on imaginaries of the ideal city is an important method to illustrate the power of ideas, imagination, representations and even visions, and how these dimensions influence the way in which cities are organized and lived. In this article, we argue that one current and important city imaginary in a Swedish context is the gender-equal city. In this imaginary, the gender-equal city becomes a symbol for the open, tolerant, bustling, safe city, a city aiming to attract the middle and creative classes. However, at the same time, the imaginary of the ideal, gender-equal city is highly ambiguous. This ambiguity will be discussed throughout the article. Based on present planning projects in the city of Umeå in Sweden, we will discuss how the imaginary of the gender-equal city is presented, filled with meaning and used in place marketing, with the overall ambition of discussing the possibilities and pitfalls of what we call the gender-equality planning strategy. The aim of the article is to study how the city of Umeå is acting to create a gender-equal city and what kind of imaginaries these practices build on. The material consists primarily of a case study focusing on projects that aim to create an equal city, and also includes analyses of policy documents and media reports. This study illustrates how imaginaries are produced through local projects and different imaginaries provide different spaces for politicizing gendered power relations.  相似文献
