The article investigates how humans ‘networked’ wet nature and how this affected the shaping of Dutch society. First, it takes a grand view of Dutch history and describes how wet network building intertwined with the shaping of the Dutch landscape, its economy and its polity. Second, it investigates the specific challenges of wet network building—integrating potentially conflicting uses of water into one design—for the case of the national fresh water supply network (1940–1971). Finally, it discusses ecological damage, emerging new risks and cultural patterns related to wet network building. 相似文献

This study shows how control over delicately balanced supply chains from raw material to the final product shifted from one national industry to another. By 1920, Dutch cinchona producers and quinine manufacturers dominated the international cartel that controlled the worldwide production and distribution of quinine (an antimalarial), quinine sulphate (a semi-finished product) and cinchona (the raw material). Twenty years earlier, however, this cartel had been controlled by the German pharmaceutical industry. How can we understand the shift of power in the world’s first pharmaceutical cartel? We argue that the internal shift of power was largely the result of the following three factors: a global industrial laboratory revolution; the vertical integration of a transoceanic network of cinchona producers, quinine manufacturers, (colonial) scientists and state officials across the Dutch Empire; and Germany’s economic isolation during the First World War. 相似文献

In this paper we examine the enigmatic but plentiful hand-molded, baked-clay objects known as Poverty Point Objects (PPOs) from a number of different facets. Although the vast majority of these Terminal Archaic artifacts are found in the Lower Mississippi Valley, they also are found at sites as far north as Clarksville, Indiana, and as far east as the Atlantic Coast of Florida. Although most archaeologists generally assume PPOs were used primarily for roasting food, we consider a variety of other possible functions, including their use in boiling water and as symbolic tokens linking the far-flung Poverty Point culture area. We demonstrate that even though a few other archaeological cultures in the world used round clay balls for cooking, the Poverty Point culture was unique in the care, variety, and standardized forms of its baked-clay objects. We discuss the various PPO types and their possible functions in nine distinct regions in the southeastern United States and, based on our thin-section analyses of 66 samples, we demonstrate that PPOs circulated among different sites in these regions. 相似文献

Abstract Before timber and stone houses were introduced to northern regions, varieties of turf houses were the most commonly used architecture. These houses had a wooden structure encapsulated in a shell constructed of grass turf. The different ethnic groups of the north built their houses in different styles and constructions, but the general principle was the same. The Norse of North Norway and also on the North Atlantic islands had a tendency to build their houses on top of the ruins of previous houses. After a few centuries this arrangement produced a settlement mound of highly organic soil. In the research literature, both the turf architecture and the settlement mounds have been described as adaptations to and a function of marginality and lack of timber. This paper reports an effort to test the idea that turf houses on top of settlement mounds may have been a finely tuned ecological system that made use of the capacity of organic soil to produce heat. 相似文献

Abstract This article describes a case where an attempt was made to introduce TEK/IK into a conflict between Sámi reindeer owners and environmental institutions. The conflict was brought on by the establishment of a national park in Southern Sámi areas in Norway. At first, the Sámi were in favour of the park, but later on their attitudes changed as the content of planned national park developed. The reindeer owners discovered that the size of the park would be reduced, leaving out what they thought were significant areas in need of protection. They saw the encouragement of increased tourism activities as a threat to reindeer herding and felt alienated by the number of representatives they received in the park management structures. On the basis of these observations reindeer owners protested, but were ignored. As researchers well-established in the Southern Sámi area, we were brought into conversations regarding the park as the local reindeer owners searched for ways of bringing new arguments into the process. At this point we thought TEK/IK represented an opportunity to add weight to Sámi perspectives. As the title of this article indicates, as push came to shove we did not succeed in making room for local participation in our TEK/IK project, despite these existing on-going relations. The article attempts to understand what happened. Our analysis is based upon a perception of TEK/IK as not one, but at least two co-constituted knowledge practices. The premise is that research failures are as important to publish as successes. Our joint ethnographic experience has methodological implications for future TEK/IK research. 相似文献

Dreams and Discourses (1627) by Francisco de Quevedo is a Baroque satirical work composed by five dreamlike narrations that criticize the moral decadence of seventeenth-century Spanish society. Traditionally, it has been read as a conservative Catholic text that conveys an official view of truth and morality. This article attempts to question that reading by addressing the use of subversive strategies, such as wordplay and ambiguity. Through an analysis of the paratext, the narrative voices, and the satire of popular trades—e.g., bankers—the article sheds light on the text's self-erosion of established moral and epistemological values. It concludes that behind its apparent religious correctness, the work reflects on the fundamental opacity of language. Theoretically, Quevedo's satire is understood as a disseminatory artifact following Derrida in Dissemination. 相似文献

In this article, the author analyzes how Salvador Espriu in La pell de brau (re)builds the myth of Sepharad that refers to the Hebrew name of the assembly of the medieval Hispanic kingdoms. La pell de brau is a work that opens the "collective cycle" toward a "we" framed within a specific historical context. The poet criticizes the unified vision of the Spanish nation and of the Catholic religion. The (re)construction of the myth of Sepharad not only reflects the crisis of the subject in search of an identity in an intolerant Spain after the civil war but also subverts the myth of the Spanish nation as created by the doctrine of National Catholicism under Franco. 相似文献

Keweenaw National Historical Park (hereafter KNHP) is one of a periodically growing list of partnership parks developed in response to changing ideals of what the National Park Service ought to preserve and interpret. Established in 1992, KNHP and some other newer parks are intended by Congress to be public–private partnerships. This paper illuminates how KNHP stakeholders used information vacuums to intensify competing narratives regarding landscapes in a partnership park. Ethnographic fieldwork illustrates that stakeholders’ competing narratives complicate KNHP's management. Furthermore, this case study highlights the need for historic preservation professionals to build trust and to communicate effectively with all stakeholders in communities with historic preservation programs. Within a social group, insiders’ knowledge construction guides ideas of landscape aesthetics. 相似文献

Platt National Park, Oklahoma, was the smallest national park in the United States until it was combined with an adjacent, reservoir-centered recreation site in 1976 to form Chickasaw National Recreation Area. Set aside as Sulphur Springs Reservation by agreement with the Chickasaw Indians in 1902 and designated a national park in 1906, Platt is the only American national park to be demoted since World War II. The story of Platt's creation and demotion reflects the changing mission of the National Park Service (NPS), shifting images of nature and recreation among the American public, and broader social forces that frame park purposes. What started as local boosterism of hydrotherapy in cold mineral springs grew into one of America's most visited national parks by the 1920s. Despite its popularity, Platt lacked both scenic grandeur and political influence; it did not fit prevailing images of wild nature among NPS bureaucrats and the urban elite who formed the core of the environmental movement; it was too small, too humanized, and too ordinary. As images of people embedded in nature have gained wider acceptance in recent decades, would this small, geographically distinctive, and culturally rich “park of the people” have met a similar fate today? 相似文献
