The Mesopotamian landscape was shaped by urbanization, population growth and trade during the 4th millennium bc. The Uruk expansion, an expansion of south Mesopotamian material culture to nearby and far-off regions started about 3700 bc. North Mesopotamian and Anatolian settlements formed a network with south Mesopotamia, which collapsed about 500 years later. This period has puzzled archaeologists for a century with different explanations being given for what this expansion was, how it happened and for what reasons. In this article I will focus on the interconnection between the two regions and how this may have created the expansion. I will use the archaeological material to study possible ideological changes. To explain how this happened I will show how the north Mesopotamian settlements functioned as middlemen in a trading network where they connected the resource-rich areas in Anatolia with the alluvial plains. The north Mesopotamian settlements exploited their position between the two regions where they could control the trading routes. This led to a lot of changes in the northern regions that do not necessarily mean that this was an occupied region or a region where decisions were dictated by leaders in south Mesopotamia. 相似文献

AbstractResearchers use a mathematical model to perform a counterfactual study of the 1854 Charge of the Light Brigade. They first calibrate the model with historical data so that it reproduces the actual charge's outcome. They then adjust the model to see how that outcome might have changed if the Heavy Brigade had joined the charge and/or if the charge had targeted the Russian forces on the heights instead of those in the valley. The results suggest that all the counterfactual attacks would have led to heavier British casualties. However, a charge by both brigades along the valley might plausibly have yielded a British victory. 相似文献

The development of new generic technologies occurs within traditional structures of industry-government interaction, but also unleashes a process of 'creative destruction' generating new institutional patterns. This article, focusing on biotechnology, describes and compares policy processes and institutional arrangements in Australia and Sweden. The Swedish biotechnology sector displays a pattern of fragmentation and relatively weak state steering. Australia, by contrast, has implemented a set of comparatively coordinated regulatory and other measures to foster the growth of biotechnology. This observation contradicts the characterisation of Sweden as a 'strong state' economy, and challenges the depiction of Australia as lacking in state steering capacity. The relative open-endedness of the search in these countries for a mode of regulation of biotechnology suggests that the role of the state in economic restructuring today is fundamentally distinct from that of earlier periods. 相似文献
