This article evaluates the current state of paleoethnobotany since Hastorf’s 1999 review published in this journal. We discuss advances in methods, ancient subsistence reconstructions, the origins and intensification of agriculture, and how plants inform on issues of political economy and identity. Significant methodological developments in the extraction, identification, and analysis of starch grains and phytoliths have led to advancements in our knowledge of early plant domestication and the transition to food production. Paleoethnobotanists increasingly are using more complex quantitative techniques to characterize their data, which have resulted in more nuanced interpretations of plants that fall within the purview of social archaeology and allow us to address issues related to gender, identity, and ritual practice.  相似文献

Strontium isotopic analysis has been proposed as a suitable method to determine the primary production location of ancient plant ash glasses. The technique is based upon the assumption that Sr enters this glass type with the plant ash used as a flux material, and that the 87Sr/86Sr ratio of the resulting glass reflects the geological provenance of that flux. In such case, the bulk Sr isotopic composition of the bedrock should be inherited unchanged in the plants growing on that bedrock. Different types of plant ash glasses have been shown to have widely differing 87Sr/86Sr compositions. In this study, the 87Sr/86Sr composition of several plant species growing on different bedrock types is measured, and compared to the bulk Sr isotopic composition and petrology of that bedrock. The paper shows that the 87Sr/86Sr ratio of these plants is a function not only, or even mostly, of the local geology, but also of the Sr isotopic composition of the total water consumed by that plant. This is highly likely to be both plant species dependent and dependent on the small-scale hydrology of the area immediately surrounding the plant. In this way, no definite relation between the isotopic composition of a geological outcrop and the plants growing on this bedrock can be inferred. Hence, the isotopic composition of a plant ash made from such plants is uncertain and moreover species dependent. Though groups of plant ash glasses can certainly be compared in time and space using Sr isotopes, it may prove difficult to ascertain a plant ash glass type to a specific geographical-geological region.  相似文献

The nutrition programs that developed in Montreal Protestant schools during the 1970s attest to a deepening awareness of child and adolescent welfare. The combination of grassroots activism and government support that brought about these initiatives took place in the context of post-Quiet Revolution Quebec, when Montrealers were grappling with the role that the newly activist state should play in social life. At the same time, school nutrition reform was part of a broader ongoing renegotiation of state responsibility. Both in Canada and the United States, governments were steadily assuming a mantle of responsibility for expanded liberal rights.  相似文献

By bringing to bear previously unstudied Soviet archival documents and conducting firsthand interviews with former diplomats, the article traces the ways in which the Soviet Union sought out opportunities to reinvigorate deteriorated Soviet?Iranian ties through cultural organizations and events in Iran during the decades following World War II. A variety of Soviet cultural representatives—from wrestlers to classical musicians to scholars of Iranian literature—were marshaled for this effort, which bore unexpected fruit considering the modest expectations of the Soviet leadership, ideological differences between the two countries, and increasingly dominant US cultural projection. The connections between cultural ties and state goals, Iranian perceptions of Russia, and the Soviet/Russian sympathies of some members of the shah’s government are among sub-themes examined.  相似文献

How do we explain the behavior of states when they appear to be engaged in normative international actions that carry some cost in terms of their material interests? This essay examines the relevance of reputation and prestige for Canadian foreign policy and, in particular, the role of these concepts in relation to Canada's leadership over the creation of the International Criminal Court (ICC). It argues that Canadians and Canadian policymakers care about their country's international reputation and are motivated by the desire to gain prestige. Ottawa's decision to support enthusiastically the creation of an international criminal court demonstrates how the interaction of the Canadian self-identity as a good international citizen and the desire to be recognized as such translates into foreign policy.  相似文献

Central banks worldwide are developing, piloting and launching new central bank digital currencies (CBDCs). As the hub for the central banking community, the Bank for International Settlements (BIS) promotes a curiously botanical CBDC imaginary. From ‘money flowers’ to ‘tree trunks’ and a ‘strong canopy’, This helps to naturalize CBDC without clarifying its sociopolitical implications or envisioned monetary future, such as geopolitical tensions and financial fragmentation, new modes of financial interaction or the strengthened role of central banks. While omitting the paradoxes and ambivalences of CBDC, the imaginary of the BIS structures the enfolding discourses and allows the bank to function as a think tank for financial policy-making.  相似文献
