The haunting picture of a disappearing Aral Sea is just part of an overall environmental crisis in the Aral Sea Basin, where millions of people are dependent on agricultural production around the flows of two main rivers, the Amu Darya and Syr Darya. Forced cotton cultivation in the former Soviet Union, in the context of inefficient agricultural organization and production, caused water mismanagement, salinization, water and soil contamination, erosion and the desiccation of the Aral Sea. In the post-Soviet era of ‘transition’, the governments of the Central Asian states and international donors have tried to mitigate the impact of the crisis and contain its scope. Resource-based tensions in the region reflect national (and sometimes ethnic) interests vested in the crucial agricultural sectors that provide foreign exchange and food. Although the Central Asian governments are gradually formulating regional water, land and salt management strategies, the room for manoeuvre that exists to implement policies which would immediately improve the environment, such as efficient water management and sustainable land use, is not being sufficiently utilized.  相似文献

This paper presents and discusses the Neutron Activation Analysis (NAA) results newly obtained from pumice pieces found decades ago at the Egyptian sites of Maiyana, Sedment, Kahun, and Amarna – now in the collections of the Ashmolean Museum, Oxford, and the Petrie Museum of Egyptian Archaeology, London – which could be successfully related to several volcanic eruptions in the Mediterranean. The work contributes to the constant accumulation of knowledge concerning the first appearance of pumice from the so-called Minoan eruption of the Santorini volcano. In addition, it unexpectedly sheds more light on the long-distance trade of Mediterranean volcanic material in the Bronze Age world by disclosing another connection between Lipari and the Eastern Mediterranean.  相似文献

ABSTRACT

Çatalhöyük was first discovered as one of the earliest urban settlements in the late 1950s and excavated by James Mellaart between 1961 and 1965. The 9000-year-old town in central Turkey rapidly became famous internationally due to the large size and dense occupation of the settlement, as well as the spectacular wall paintings and other art that were uncovered inside the houses. Since 1993, under the direction of Ian Hodder, research at Çatalhöyük has pioneered a reflexive approach to archaeological practice, in which information is permanently open to reinterpretation by both scholars and the public. This approach acknowledges the mutual dependence of knowledge and the underlying research, to which end the Çatalhöyük Project decided to make its records available via the Web and to invite public comment since its onset. After 25 years of excavation, the project’s digital assets now amount to close to 5TB, including formal textual and numeric records, freetext documents, audiovisual materials, and a comprehensive collection of spatial data. The reflexive method, or ‘documentation of the documentation process,’ adds a separate layer of information that specifies how data have been gathered, and facilitates critique, understanding, and the evolution of knowledge.

In this paper we lay out our vision of an interactive archive that provides access to the multi layered information contained in this massive amount of data and how web technological advances have been incorporated into the digital data management at Çatalhöyük. Ultimately, the goal is to support an interdisciplinary process of assembling data into arguments on the basis of multiple lines of evidence. The ‘Living Archive’ will enable intuitive engagement across the entire variety of research, making use of the rich reflexive information stored with the data. The results of new analyses can in turn be reintegrated with the already existing data. The application will use open standards so that the knowledge gathered at Çatalhöyük can be linked with other projects that follow similar publication procedures based on the semantic web approach.  相似文献

Scientific evidence suggests that rising levels of anthropogenic underwater sound (“ocean noise”) produced by industrial activities are causing a range of injuries to marine animals—in particular, whales. These developments have forced states and development proponents into acknowledging ocean noise as a threat to marine economic activity. This paper delivers a Gramsci‐inspired critique of the modernizations of ocean noise regulation being wrought by science, state and politics. Gramsci was acutely interested in the dynamic and social nature of scientific research, and his writings affirm science's powers and ambitions. At the same time, he was keen to observe how science participates in the process he called hegemony. Using examples drawn from Canada's West Coast, I suggest that capital is engaging ocean noise not only as a regulatory problem issuing from legal duties and legitimacy concerns, but opportunities linked to the commercialization of ocean science.  相似文献
