Grasslands pose a particular problem for archaeological survey involving artifact assessment, as no material is plowed up to the surface. Although finds in molehills are often the only source of information available on sites with such low visibility, an archaeology of molehills has thus far been largely disregarded. Yet, by applying a low-cost and time-efficient methodology, both the potential and the pitfalls of molehill archaeology come to the forefront. At the medieval harbor site of Monnikerede, it was possible to assess material culture and to locate certain structural elements. However, when artifact densities were compared with the underlying geophysical anomalies, a more complex relationship appeared at the level of individual features. 相似文献

Abstract: Within the European Union, an internal liberalisation of cross‐border labour mobility for EU citizens is currently being combined with the tightening of control and management efforts at the external borders. At the same time, attempts are being made to strategically select immigrants from new member states as well as from outside the EU who will be of economic value. In this paper we argue that by implementing such protectionist and selective immigration policy, the EU has come to resemble a gated community in which the bio‐political control and management of immigration is, to a large extent, the product of fear. Often fear manifests itself in terms of fear of losing material gain, eg the anxiety of losing economic welfare or public security. More often, however, this fear relates to the entrance of the immigrant, the stranger and is, as such, associated with a fear of losing a community's self‐defined identity. These perceived threats to a community's comfort lead to the politicisation of protection, whereby the terra incognita beyond the border is justifiably neglected due to the indifference and the intentional blindness shown to the outside. Hiding in a gated community in order to protect this comfort zone and trying to exclude outsiders, ‘Others’, from the community, is not only in vain since the desire for completion of the Self can never be fulfilled, but what remains still more troublesome, is that this tendency will sustain and reproduce global inequality and segregation, both in the material as well as symbolic sense. 相似文献

The technology of the end products i.e. blades and points in Late Pleistocene stone artefact assemblages from Klasies River, South Africa, and the Nile Valley, Egypt, are compared. The comparison includes univariate and multivariate analysis of metrical attributes enhanced by graphical biplot displays. The end products in these assemblages are either dominantly points or blades and this is related to the core reduction strategy adopted. The MSA 11 from Klasies River and the Nubian Complex industry from the Nile Valley are point industries made in the Levallois tradition, while the MSA 1 from Klasies River and the Taramsan from the Nile Valley may be non-Levallois or adapted Levallois blade industries. Dating of the assemblages shows the changes between dominant core reduction strategies are sequential and time restricted in both South and North Africa. It is concluded that variability of the same kind occurs in Middle Stone Age and Middle Palaeolithic assemblages south and north of the Sahara in the early Late Pleistocene.Dans cet article, les technologies des produits recherchés, des lames et des pointes, pour certains ensembles lithiques de Klasies River, Afrique du Sud et la Vallée du Nil, Egypte, sont comparées. Cette comparaison implique des analyses univariées et multivariées de variables métriques biplot. Les produits recherchés sont bien des pointes que des lames, selon les stratégies dexploitation adoptées. Le MSA II de Klasies River et le Complexe nubien de la Vallée du Nil sont des industries à pointes issues de la tradition Levallois. Par contre, le MSA I de Klasies River et le Taramsien de la Vallée du Nil évoquent une technologie de production non-Levallois ou Levallois modifiée. Les éléments de datation disponibles indiquent que les changements dans la prépondérance des stratégies dexploitation senchaînent dans une séquence chronologique bien identifiable, aussibien dans lAfrique du Sud que lAfrique du Nord. On arrive à la conclusion quune variabilité du même caractère est attestée dans les ensembles du Middle Stone Age et du Paléolithique moyen au sud et au nord du Sahara, pendant le Pléistocène supérieur ancien. 相似文献

The Influenza Pandemic of 1918–20 in medical debate. The history of the so called Spanish Influenza 1918–1920 is summarized especially in regard to the developments in medical debate. In Germany, Richard Pfeiffer, who had discovered Haemophilus influenzae after the previous pandemic 1890 / 91, managed it to defend his thesis that his “bacillus” was the causative agent of the flu, by modifying his theory moderately. The Early Virology of influenza in postwar times was still fixed to bacteriology and did not yet have the force of school‐building. Aggressive therapy, e.g. with derivatives of chinine, were used in a concept of polypragmasy. The connection between influenza in animals and influenza in mankind was unknown or of no major interest till the rise of virology as an academic discipline in the 1950s. Since the outbreak of avian influenza in Asia 1997 virological archaeology is challenged to fill the historical part in the attempt to fight the threat of the highly pathogenic bird flu. In the beginning of the “short 20. century” politicians and doctors had no interest to build a “monument” of influenza. Today, virological reductionism does not have the power to (re‐)construct such a monument. 相似文献
