Four blue-glazed faience jars, on exhibition in the Louvre Museum, are referred to as the canopic jars of Rameses II. Their recent typological re-examination rendered this original assignment questionable. In order to clearly determine their use, a study of two successive organic residues from the canopic jars, using molecular biomarkers analysed by GC-MS and LC-MS and absolute dating by 14C, was initiated. The results revealed that these two materials were not contemporary to the reign of Rameses II. The first one, scraped from the interior face of one jar, was identified as an unguent made of coniferous oil and animal fat and dated from the Third Intermediate Period. The second one, originally stored with glued linen inside one jar, is likely an embalming substance, made of pure vegetable resin (Pistacia) and dated from the Ptolemaic Period. These results clarify a controversy which has been lasting over a century. The famous blue-glazed faience jars are not the canopic jars of Rameses II but are confirmed as situlae which were reused at least two times: first to store unguents during the Intermediate Period and later to store embalming packages of an unknown person during the Ptolemaic period.  相似文献

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.  相似文献

Aboriginal people have occupied northern Alberta since the end of the last ice age. For most of that time they travelled across the land by foot, producing complex networks of trails, many of which may have great antiquity. Aboriginal people also modified the landscape extensively by the use of controlled burning. Lastly, they are immersed in and “read” the land as places with multiple cultural meanings, which in turn helped shape their cultures and identities. Together, these elements indicate the existence of a series of overlapping cultural landscapes for which the cross-country trails and waterways provide the grid. This article addresses the importance of traditional trails for identifying the cultural landscapes of northeastern Alberta and points to the rapid disappearance today of knowledge about such trails. It considers how archaeological investigations done in Alberta for Impact Assessment purposes fail to consider either trails or cultural landscapes in their surveys or to consult with Aboriginal people. As a result, government Review Panels making recommendations for whether or not an industrial project should be approved are basing their findings on incomplete information about Aboriginal land uses and meanings.  相似文献

There is a common perception that infrastructure megaprojects are difficult to implement, as they face many obstacles (cost overruns, political barriers and time delays). This was particularly the case in the UK where many projects were difficult to develop given a complex, centralized and turbulent financial context (e.g. the jubilee Line extension, the Eurostar project). Despite this complex British system, London is developing the Crossrail mega infrastructure project which is recognized to be on time and built within a planned budget. The paper aims to analyse the reasons for the development of this project in a turbulent political and financial British system. The main argument I defend is that Crossrail benefited from the constitution of a specific and localized growth coalition. Revisiting the notion developed by Logan and Molotch, I show how the aggregation of different interests (political and economic) has been essential in the concretization of this project. Actors motivated by the will to promote the growth of London and to sustain the growth of population and jobs have been at the forefront to defend Crossrail. These elements have put Crossrail on a route of success. The paper concludes by characterizing and analysing such a success.  相似文献

French medical journals take the lead among the 1 385 titles of the statistical survey (15.4%). Efficient tool in communication, with an important publishing market, linked to the rise of medicine in the 19th century, prosperity of medical journals do not only mean rise of specialties. Monthly periodicals dominate quickly the publishing market which is also characterized by complex links between generalist and highly specialized medicine, public health and professional training.  相似文献

Examining Charles II's changing posthumous reputation from his rumored deathbed conversion to Catholicism through the political upheaval of the late-seventeenth and early-eighteenth centuries demonstrates the profound effects affairs of state during the reigns of James II, William III, and Anne had on ideas of kingship. From elegists' depictions as the glory of the Stuart monarchy, Charles became James' feared counterpart during debates over the Copies of Two Papers Written by the Late King Charles II, and finally a distinctly human ruler. Published posthumous representations of Charles II suggest increasing willingness to consider kings as fallible men who made contestable decisions.  相似文献

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献
