This article explores how in the years after 1980 a spectrum of historical actors came to see petroleum platforms in the Gulf of Mexico as a necessary part of the Gulf ecosystem and how such views affected platform removal policies. Through a discourse analysis of the Rigs‐to‐Reefs program, in which old offshore petroleum facilities were converted into artificial reefs, this article examines how actors presented to the public their notions of the relationship of the Gulf ecosystem with technological offshore structures. Through this case we see how ideas of technology and nature were mutually constructed via discourses and what affect that had on policies.  相似文献

The appearance of rich and diverse funerary practices is one of the hallmarks of the Late Epipalaeolithic Natufian in the Levant. Numerous burials at a number of sites excavated mostly in the Mediterranean zone of the southern Levant have fed into the interpretation of the Natufian as a sedentary society of complex hunter-gatherers. Here, we report on the human remains recovered from Shubayqa 1, a well-dated early to late Natufian site in northeast Jordan. The majority of the minimum of 23 individuals that are represented are perinates and infants, which represents an atypical population profile. Ground stone artifacts and traces of colorants are associated with some of these individuals, providing a rare insight into funerary treatment of subadults in Natufian contexts. We interpret the Shubayqa 1 evidence in the light of current and ongoing debates concerning Natufian burial practices and the issue of social complexity.  相似文献

This article demonstrates the relevance of future discounting behavior to studies of prehistoric subsistence strategies. The case study of Agave spp. bajada cultivation among the Classic Period, a.d. 1150–1450, Hohokam of southern Arizona illustrates how slight discounting of future rewards can significantly alter agriculture investment strategies. Despite a higher kcal/hour return than maize agriculture, agave cultivation lessened or ceased in several communities during a time in which intensification would be predicted due to inferred subsistence stress. We surmise the decade-long maturation of agave made it unattractive relative to more immediate return resources in any context that presented risks to land tenure. The cessation of agave cultivation can be understood on two levels of explanation. The long-term investments required by agave and tendency to discount future rewards are the ultimate causes. Political and social instability during the tumultuous Classic period, causing increased insecurity in land tenure, are the proximal causes.  相似文献

This article aims to dissect Thomas Abbt's (1738–1766) theory of aesthetic patriotism as laid out in his On Dying for the Fatherland (1761) and his prize-essay On Mathematical, Metaphysical and Moral Certainty (1763). Aesthetic idioms, such as the emphasis on the intrinsic pleasure from the order and beauty of virtue, had been invoked throughout the eighteenth century to vindicate the morally optimistic view of humanity against the sceptical vision of an exclusively utility-centred mankind. In the post-Montesquieu debates on the moral foundations of modern politics, German-speaking authors in particular, from both republics (Switzerland) and monarchies (Prussia), appropriated the aesthetic idioms in order to reject those theories which grounded patriotism in some sort of self-interest or proclaimed it redundant in modern society. Thomas Abbt was one of the most prominent representatives of this intellectual position. Combining the general emphasis of Shaftesbury on the role of aesthetic appreciation in moral and political agency with the more specific German Baumgartenian analysis of ‘beauty’ as a central principle in human ‘empirical psychology’, Abbt argued that patriotism in modern monarchies could be grounded in an aesthetic passion of enthusiasm generated through sensuous examples of great virtue. The example of a king fighting for his country on the battlefield could inspire monarchical subjects to follow his example as well as regenerate patriotism among them. Abbt was adamant that patriotism based on aesthetic foundations had to be supported and stabilised by a pervasive patriotic culture of remembrance and emulation of dead heroes through the fine arts, as well as by a system of meritocratic honour in the army.  相似文献

New Approaches to Innovation Policy: Some Norwegian Examples   总被引:1,自引:0,他引:1  
The paper describes and assesses three Norwegian innovation policy tools. The tools cover three different models of strengthening firms' innovation capability, i.e. direct financial support, broker and advisory systems and technology or knowledge centres. The tools include some new elements in innovation policy design, and thus, some elements of good practice. Guidelines for good practice includes an interactive perspective on innovation support, a focus on innovation systems, context sensitivity and a regional focus, learning in the support system and receiver-oriented and proactive working methods.  相似文献
