A new, refined chronology for graves and grave‐goods in Anglo‐Saxon England has revealed a marked increase in well‐furnished female burials beginning in the second quarter of the seventh century. The present study considers what gave rise to this phenomenon and concludes that the small number of royal nuns and abbesses who figure so prominently in written accounts of the Conversion were part of a wider, undocumented change in the role of women that began several decades before the founding of the first female houses. It is argued that these well‐furnished graves reflect a new investment in the commemoration of females who came to represent their family's interests in newly acquired estates and whose importance was enhanced by their ability to confer supernatural legitimacy onto dynastic claims. 相似文献
The drive towards collaborative governance has raised critical questions about the hidden forms of power practised in consensual planning processes. In the field of water governance, the issue has been analysed in terms that treat power as an intrinsic property of actors or planning settings. Alternatively power is located in the discursive means mobilized by the human participants. Drawing from actor-network theory, this paper calls attention to the material arrangements constitutive for the practicing of power in target-driven, consensus-seeking planning. It sets focus on the obligatory passage points and factual closures through which a planning task links, for example, to ecosystems, policy principles and trajectories of governance. In the meantime, some other entities and issues may lose their planning-steering potentiality. As shown by the analysis of a river-basin planning process, the arrangements that end up steering consensus-seeking cannot be treated as merely discursive outputs operating upon a passive non-human reality. Materialities and living processes contribute to the outcome. However, the link is not deterministic. With different means of arrangement, the planning reality can – and, in the studied case, could have – end up different. 相似文献
In the scope of European Cooperation in Science and Technology–Wood Science for Conservation of Cultural Heritage (COST IE0601–WoodCultHer) (available at http://www.woodculther.org) it was agreed to produce Guidelines for the Assessment of Historic Timber Structures, covering the principles and possible approaches for the safety assessment of old timber structures of historical relevance that could be used as the basis for possible European Standards, as discussed with CEN/TC346 (Conservation of Cultural Heritage).
This approach was targeted at all those concerned with the conservation of heritage buildings. These guidelines should also help decision-making regarding the need for immediate safety measures. The aim is to guarantee that inspection and assessment measures provide the necessary data for historical analysis, structural safety assessment, and planning of intervention works, while having minimal impact on the building fabric (the original materials, structural systems, and techniques).This article provides information on the criteria to be used in the assessment of load-bearing timber structures in heritage buildings. It covers the preliminary assessment (desk survey, preliminary visual survey, measured survey, structural analysis, and preliminary report), as well as the detailed survey of timbers (with a special emphasis on visual strength grading on site) and carpentry joints. The subsequent diagnostic report and the detailed design of repairs are outside its scope. 相似文献
A variety of microfossils, originating from plant foods, become trapped in the dental calculus matrix. Processing of dental calculus allows extraction of these microfossils. The resulting data can be used to reconstruct diet at the individual and population levels as the identification of microfossils like starch grains and phytoliths to the generic level, and sometimes to the species level, is possible. However, in some archaeological sites, dental calculus deposits do not preserve well enough to be processed. To prevent the loss of information in such cases, we present a technique, called “dental wash”. It permits extracting microfossils from cryptic dental calculus deposits. In the two experimental archaeological cases presented herein we identified phytoliths, starch grains as well as a diatom fragment with this method, whereas in a control sample no microfossils were found. Moderate damage to the teeth was detected when they were already friable due to poor preservation. Minor damage to the surface of well-preserved teeth was observed. This indicates that the proposed method is efficient in recovering microfossils, but unacceptable because of damage to teeth. If the method can be refined, it will expand the potential of dental calculus analysis to a greater range of archeological sites. 相似文献
