This paper reports the combined preliminary results of the Italian Mission to Kassala and the joint University of Khartoum/Southern Methodist University Butana Project. Both groups have been carrying out extensive survey and test excavations in the Southern Atbai of the East Central Sudan, between the Atbara and Gash Rivers. This work has led to the recognition of a previously unknown culture area and ceramic tradition which spans about 5000 years and, at its peak, probably covered about 100,000 sq. km east of the Nile. This ceramic tradition, the Atbai Tradition, is associated with the development of large villages (over 10 ha) during the 4th millennium bc.
Résumé Le présent article rapporte les résultats préliminaires combinés de la Mission italienne à Kassala et du projet Butana entrepris en commun par les universités de Khartoum et Southern Methodist. Ces deux groupes ont réalisé des reconnaissances archéologiques extensives et des sondages dans le sud de l'Atbai, dans la partie centrale orientale du Soudan, entre les rivières Atbara et Gash. Leur travail a mené à la reconnaissance d'une civilisation et d'une tradition céramique auparavant inconnues qui durèrent quelque 5000 ans et qui couvraient à leur apogée environ 100,000 km2 à l'est du Nil. Cette tradition céramique, la tradition Atbai, est associée au développement des grands villages (de plus de 10 ha) au cours du 4e millénaire avant notre ère.

Remains from Paleo-Eskimo cultures are well-documented, but complete preservation is rare. Two kitchen middens in Greenland are known to hold extremely well-preserved organic artefacts. Here, we assess the fate of the Qajaa site in Western Greenland under future climate conditions based on site characteristics measured in situ and from permafrost cores. Measurements of thermal properties, heat generation, oxygen consumption and CO2 production show that the kitchen midden can be characterized as peat but produces 4–7 times more heat than natural sediment. An analytical model from permafrost research has been applied to assess future thawing of the midden. Results show that the preservation conditions are controlled by freezing temperatures and a high water/ice content limiting the subsurface oxygen availability. Threats to the future preservation are related to thawing followed by drainage and increasing subsurface oxygen availability and heat generation. The model predicts that the unique 4000-year-old Saqqaq layer below more than 1 m of peat is adequately protected against thawing for the next 70 years.  相似文献

Industrial areas play a critical role in urban and regional planning, especially for developing countries where reliable strategies for these areas can promote economic and environmental efficiency. The present study provides an integration of hybrid multi‐criteria decision‐making (MCDM) theories and Geographical Information System (GIS) processes in order to assess the suitability of an industrial location. Unlike traditional models, an efficient decision analysis demands handling uncertainties and considering dependencies between criteria. The proposed MCDM framework uses fuzzy theory because of the vagueness of experts' judgements. Moreover, Decision‐Making Trial and Evaluation Laboratory (DEMATEL) is employed to investigate interrelationships among the criteria. In the proposed empirical solution, analytic network process (ANP) principles are used to deal with systematic interactions. We considered several factors such as accessibility, topography, proximity, and socioeconomic characteristics in the decision‐making procedure for a sustainable industrial park. The system is applied to Hamadan province, Iran to determine appropriate locations that are the results of the aggregation of criteria maps in a GIS environment. The results demonstrate that accessibility and economic indicators are essential for choosing an industrial park's location. Additionally, the proposed method can be applied for an efficiency evaluation of available industrial parks.  相似文献

Policy scholars have effectively leveraged policy process models, theories, and frameworks to respond to a variety of important environmental questions. For example, how do environmental issues arrive on the agendas of policymakers? What factors contribute to environmental policy change? What are the designs and effects of institutions (e.g., policies or cultural norms) on environmental governance? In this review, we survey the field of policy process scholarship, focusing on environmental governance, with three objectives. The first objective is to catalog the policy process models, theories, and frameworks most often featured in studies of environmental governance. The second is to capture the methodological choices commonly employed in the application of these models, theories, and frameworks in environmental domains. The third is to identify how these approaches deal with issues central to environmental governance research, including time, space, and policy scale. We aim to identify trends and strategies for integrating key considerations of scale into empirical policy process scholarship.  相似文献

Secularism in Islamic countries is a hotly-debated topic which produces dramatic sociopolitical consequences on the one hand, and wide-ranging academic controversy on the other. The real social potential of secularism among Muslim populations is an issue that is not always estimated properly. The present paper first reviews some historical examples of secular cultural policy in Islamic countries. This review covers the secular reforms in four political, social, legal, and educational spheres. Subsequently, using data from the World Values Survey, it compares empirically the desirability of a public role for religion in 18 Islamic and Western countries. Furthermore, it examines the acceptability of Western secular culture in six countries in the Muslim world. Bearing in mind Casanova’s analytical approach to the theory of secularization, it comes to the conclusion that a democratic application of a secular cultural policy in Islamic countries is neither desirable nor feasible.  相似文献
