The 'buckler' motif appears isolated in the naturalistic milieu of the earliest Breton art but there are problems with a symbolic interpretation. If instead it is considered in naturalistic terms it can be demonstrated to bear a close resemblance to a form of grain store made of straw rope that was used in parts of Ireland until this century. The likelihood of above ground grain storage in the Neolithic is considered and the potential archaeological evidence for such features is reviewed. Finally reasons are advanced for the motif being centred in the Morbihan region.  相似文献

As heritage research has engaged with a greater plurality of heritage practices, scale has emerged as an important concept in Heritage Studies, albeit relatively narrowly defined as hierarchical levels (household, local, national, etcetera). This paper argues for a definition of scale in heritage research that incorporates size (geographical scale), level (vertical scale) and relation (an understanding that scale is constituted through dynamic relationships in specific contexts). The paper utilises this definition of scale to analyse heritage designation first through consideration of changing World Heritage processes, and then through a case study of the world heritage designation of the Ningaloo Coast region in Western Australia. Three key findings are: both scale and heritage gain appeal because they are abstractions, and gain definition through the spatial politics of interrelationships within specific situations; the spatial politics of heritage designation comes into focus through attention to those configurations of size, level and relation that are invoked and enabled in heritage processes; and researchers choice to analyse or ignore particular scales and scalar politics are political decisions. Utilising scale as size, level and relation enables analyses that move beyond heritage to the spatial politics through which all heritage is constituted.  相似文献

The lack of interest in history in ancient India has often been noted and contrasted with the situation in China and the West. Notwithstanding the vast body of Indian literature in other fields, there is a remarkable dearth of historical writing in the period before the Muslim conquest and an associated indifference to historiography. Various explanations have been offered for this curious phenomenon, some of which appeal to the supposed currency of certain Indian philosophical theories. This essay critically examines such "philosophical explanations."
I argue that it is not true that there was no history in ancient India, and it is not surprising that there was no developed historiography or scientific history. It is both true and surprising that there was no real importance attached to history in ancient India. An adequate philosophical exxplanation for this historica phenomenon, however, is not to be found in appeals to the influence of indigenous metaphysical theories about time and the self. A much more plausible philosophical explanation appeals instead to certain features of classical Indian epistemology.  相似文献

The first step in a hysteretic energy-based design approach of performance-based design is the estimation of hysteretic energy demand in the structure. A nonlinear response-history analysis of the multi-degree of freedom model gives an accurate estimation, but it is not suitable for adopting in design. Two alternative methods, based on the concepts of modal pushover analysis (MPA) and 2D-MPA, are proposed in this article for uniaxial plan-asymmetric structures. Application studies show that both methods are efficient. While the 2D-MPA-based method is more accurate, the MPA-based method is more suitable for design adoption. Significant conclusions are given for prospective application of these methods.  相似文献
