Siraf is well‐known archaeologically and historically as an ancient port in the Persian Gulf that prospered during the medieval period. Siraf played a leading role in facilitating maritime and terrestrial trade, connecting long‐distance Indian Ocean and China routes with those in the Gulf region. Despite its history, no previous research has been dedicated to the maritime infrastructure of Siraf. Through the ‘2012 Siraf pilot project’ a preliminary survey of the underwater and shoreline remains of this ancient port city was conducted. The site's location is unique in many respects to trade routes and logistical considerations; however, its maritime infrastructure is difficult to assess in light of the extensive threats to the site.  相似文献

Though the fourteen contributors to this volume bring varied perspectives on method, most striking is their common engagement with contextualist approaches. While some of the essays advocate a temporally and spatially extended, renewed history of ideas with debts to Arthur Lovejoy, and are critical of excessive contextualization, several either defend contextualism, or the culture concept, or offer a more robust materialist foundation for the history of thought and culture. This review focuses on the logic and metaphors used to criticize contextual methods and highlights problems with both the new history of ideas and the new materialist gestures.  相似文献

In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.  相似文献

Companies' community involvement turns out to be spatially relevant and–in many cases–to be focused on the near surroundings of the place of business. Some companies strategically align their involvement in order to systematically address local challenges. The essay at hand addresses the subject of corporate social responsibility from a local development perspective. Using the example of two family-owned enterprises based in Duisburg, Haniel and Grillo, it illustrates how socially committed companies can get involved with their local community by acting as good neighbours. Furthermore, it argues that socially committed companies can function as producers of space concerning matters of urban and local development. The specific local settings as well as the economic conditions of the local community serve as an explanatory background of the companies' involvement. The cases presented in this paper prove the firms' specific knowledge of local development needs and possibilities. This makes them qualified partners for local government actors and civil society actors. Thus, in the future, it is worth addressing corporate local responsibility from a governance point of view both in theory and in practice.  相似文献

Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city.  相似文献
