The first attempts to identify amorphous organic substances in archaeology date to the end of the 19th century and the beginning of the 20th century. The 1960s saw the development of infrared spectrometry, and then separative and mass spectrometry analyses were implemented in the 1980s. But it is only since the 1990s that extended and systematic research programmes were devoted to these substances. The number of publications has not stopped growing and is becoming exponential. To get an overview of the lipid studies in archaeology, we conceived the ARchaeological Organic residues Literature Database (AROLD) as a first structured and collaborative research tool. This paper describes the challenges of setting up such a database, details its architecture, presents the choices involved in its implementation, and discusses the possibilities of sharing and evolving this tool.  相似文献

This article discusses the scientific relations between Sweden and France in the 18th century and how the Swedes had access to the new international scientific community that was building up with the new science academies. Contemporary honours accorded to the Swedes indicate who acquired entrance to the European scientific elite and why. International recognition was often tied to personal relations, patrons and foreign travels. P.‐L. M. de Maupertuis' expedition to the Arctic Circle in 1736–1737 was an influential event. But also other Swedes than the academy elite were present in French translations. A common denominator behind the interest accorded to both groups often seems to be related to the northernness of Sweden as a unique place for performing experiments and observations. New explanations (apart from the often appealling exoticism) are sought from the experimental and encyclopedistic nature of 18th‐century science and the implications of the widespread climate discource.  相似文献

The Briand Memorandum in 1930 was the most important effort to create stronger European political unity in the interwar period. The responses by the governments of Sweden, Finland and Estonia have not been studied before. It is convenient to study these replies together and focus on possible cooperation between neighbouring countries. Whilst France was using the Memorandum to europeanize her relations with Germany, Sweden, Finland and Estonia also adopted the Memorandum to their foreign policy. As a result a common policy towards the Memorandum could not be found, despite the fact that the three countries agreed on multiple issues.  相似文献

In the last few decades optically stimulated luminescence (OSL) dating has become an important tool in geochronological studies. The great advantage of the method, i.e. dating the depositional age of sediments directly, can be impaired by incomplete bleaching of grains. This can result in a scattered distribution of equivalent doses (DE), leading to incorrect estimation of the depositional age. Thoroughly tested protocols as well as good data analysis with adequate statistical methods are important to overcome this problem. In this study, samples from young fluvial sand and flood plain deposits from the Elbe River in northern Germany were investigated to compare its depositional ages from different age models with well-known historical dates. Coarse grain quartz (100–200 μm and 150–250 μm) and polymineral fine grains (4–11 μm) were dated using the single aliquot regenerative (SAR) dose protocol. The paleodose (DP) was calculated from the DE data set using different approaches. Results were compared with the development of the Elbe River, which is well-documented by historical records and maps covering the last 1,000 years. Depending on the statistical approach it can be demonstrated that depositional ages significantly differ from the most likely depositional age. For the investigated coarse grain quartz samples all ages calculated from the MAM-3UL, including their uncertainties, are within the historical documented age. Results of the polymineral fine grain samples are overestimating the historically documented depositional age, indicating undetectable incomplete bleaching. This study shows the importance of using an adequate statistical approach to calculate reliable OSL ages from fluvial sediments.  相似文献

Early gender archaeology formulated two statements: men are visible, women are invisible, and men work in hard materials, women work in soft materials. We discuss these dichotomies in connection with nineteenth-century folklore and an excavated eighteenth-century cottage at a summer-farm. We conclude that much of the gendered order-of-work tasks broke down in pragmatic day-to-day life, especially by women crossing the gender border. However, social chaos was held at bay by ritual acts and magic objects.  相似文献

ABSTRACT The core‐periphery model of the new economic geography has two “dramatic” implications: catastrophic agglomeration and locational hysteresis around the symmetry breaking level of trade freeness. In this note, we study a generalized version of this model with constant elasticity of substitution (CES) instead of Cobb‐Douglas upper tier preferences. The possibility of a continuous and easily reversible transition from symmetry to agglomeration now arises. One of the most prominent results of the new economic geography literature—the catastrophic consequences of small parameter changes—therefore, hinges crucially on specific functional forms for consumer preferences.  相似文献

In this article, I investigate “spatial scale” as an aspect that needs to be more carefully addressed in the discussion and planning of “sustainable urban forms”. Focusing on the Malmö–Lund region in Sweden, I discuss problems of scale as related to the new take on sustainability in Malmö planning documents, especially the update of the Malmö comprehensive plan from 2005. The article is divided into three sections. First, I discuss the concept and problem of spatial scale, contextualizing it in theory as well as in recent discussions on urban transformations. Second, I briefly discuss the discourse of sustainable urban forms, pointing out some scale-related issues that need to be more carefully addressed. In the third and main section of the article, I investigate plans and projects for urban development in Malmö, focusing and elaborating on spatial scale and discussing the findings in terms of three kinds of scale stabilization: in terms of territory, size and hierarchy. The article concludes with a call for further work for the possibilities of a more dynamic and multi-scalar approach in urban planning.  相似文献

The article argues that the present Danish urban policy and urban democracy can be characterized by a striking duality and tension between: (1) Participatory empowering welfare oriented community strategies, which targets deprived districts and neighbourhoods, which are based on notions of the inclusive city. This trend is founded on priorities of radical democracy, social justice, inclusion and citizens empowerment; (2) Neo-elitist/corporative market driven strategic regional and global growth strategies, which are based on notions of the Entrepreneurial Globalized City and where urban policy becomes a question of facilitation of the “growth machine” and neo-liberalized urban authoritarianism. The article discusses dilemmas for overcoming the growing tension between elitist neo-corporate growth regimes, which are in operation via “Quangoes” and closed elite networks, and community empowerment and welfare oriented policy in the age of globalization. Taking the stand of community empowerment and welfare policy, the article conclusively discusses ways to shape a new inclusive politics of difference including using “positive selectivism” as part of an empowerment strategy.  相似文献
