The collection of early medieval window glass found in the abbey of Baume‐les‐Messieurs (Jura, France) is exceptional because it dates to the end of the eighth century, and due to the number of fragments as well as their state of conservation. Different colours and forms have been identified. These pieces are a rare opportunity to address the glass craft, its recipes and techniques for a phase of its history that has remained little known. Analyses in PIXE–PIGE prove that, in addition to fragments from two soda glass items, the pieces are made from wood‐ash glass. Most of them probably came from the same production and the raw material is present in the region. At this early stage of wood‐ash glass production, the glassmakers had mastered the glass as well as the colour processes.  相似文献

Hong Kong, like other countries with developed economies, is experiencing significant population ageing. The shift in the population age structure results from a combination of decreasing mortality rates and prolonged low fertility rates. This paper investigates the economic impact of changes in a population's age structure. We forecast on sex-specific labour force participation rates (LFPRs) and the economic dependency ratio (EDR) using different scenarios. Our results show that the below-unity level for the EDR—prevalent since 1996—will exceed unity in 2015 and rise steeply thereafter. By 2036, the projected EDR will reach an unprecedented high of 1.4, where every three economically-inactive persons will be supported by two economically-active persons in Hong Kong. This projection not only reflects a significant age shift towards the older end of the age spectrum, but is also driven by declining LFPRs among men.  相似文献

日本单一窗口构建属于“单一系统”模式的成功典范。自1978年启动第一个电子通关系统——空运NACCS系统开始,通过30年的努力,分三个阶段实现了以海关NACCS系统为核心系统的单一窗口。在其构建过程中,NACCS的核心系统功能,领导机构与运营主体以及立法先行、动态修订的单一窗口法律保障是其成功的关键所在。因此,分析日本单一窗口的构建进程可以发现,解决单一窗口的瓶颈与障碍不在于电子技术,而在于制度构建与机构整合。强有力的单一授权领导机关,单一窗口制度构建的思维转换,制度改革与机构整合的法律化,这三项内容是单一窗口得以顺畅有效运作的重要支柱。  相似文献

ABSTRACT

Archibald MacMechan’s regular column in the Montreal Standard entitled “The Dean’s Window” (1906–1933) is an important index to educated antimodernist literary values. MacMechan brought his reading of world literature into his appraisals of the Canadian scene, through his groundbreaking work, Headwaters of Canadian Literature(1924). In a 1912 “Dean’s Window” column, MacMechan, a published poet, opened with a poem of his own, “The Ballade of Canadian Literature,” which anticipated F.R. Scott’s “The Canadian Authors Meet”—itself a seminal work of early Canadian modernism. By no means binaries, the degree to which modernism and antimodernism could resemble each other is manifest in MacMechan’s and Scott’s poems, even though Scott’s poem eviscerates the Canadian Authors Association, an organization of which MacMechan was a founding member.  相似文献

?????The 1621 painted glass window in the Mildmay chapel of St Leonard’s church, Apethorpe, Northamptonshire, belongs to the revival of figurative glass in churches during the first half of the seventeenth century. Its four subjects, the Fall of Adam and Eve, Christ’s crucifixion and resurrection, and the Last Judgement, express orthodox reformed belief in original sin and salvation only through faith in Christ’s saving grace. But the window’s design and unusual iconographic details are atypical of the period. Theme and imagery closely parallel sixteenth-century bible illustrations and both can be understood in relation to the volume of meditations compiled over her lifetime by Grace, Lady Mildmay, who was the patron of the chapel. The paper argues for her close involvement in the evolution of the imagery; the window can be seen as a visual equivalent of her meditations, and expresses her preoccupation with sinfulness, redemption, resurrection, and the afterlife.  相似文献

Thirty shards of medieval window glass from Elgin Cathedral in north‐east Scotland have been subjected to compositional analysis by portable X‐ray fluorescence and scanning electron microscopy – energy‐dispersive X‐ray spectroscopy. Comparison with previous analytical studies suggests that the majority of the glass was probably produced in France, while a smaller group may have been made in Germany. Significant differences in base glass composition were observed between colours. Two distinct blue glasses compositions were identified. The composition of the grisaille paint differs from paint on the continent, providing the first evidence that it was made using local Scottish lead and iron pigments. This work represents the largest analytical study of Scottish medieval window glass yet undertaken and presents insights into the transfer of medieval materials, technologies and trade routes.  相似文献

The article explores how political tensions developed around the issue of Canadian water export, how policy solutions and alternatives to the problem were offered, and how finally it came to be recognized by the national government. The water export issue reached the formal agenda after a lengthy period of being denied serious consideration. However, it is arguable that agendas are set if an issue receives attention from policy decision makers. This is because an issue's ascension to agenda status is not an indication of how it is actually going to be decided upon. The case of water export demonstrates that the government adopted a policy solution consistent with assumptions prevalent at the time and acceptable among elected decision makers. Yet, the solution was contrary to the expectations of those who demanded a complete water export ban in Canada.  相似文献

Structural walls of old historical structures are either blind or have openings for functional requirements. It is well known that in and out of plane responses of structural walls are affected by the size, locations, and arrangements of such openings. The purpose of this investigation is to study the window opening effects on static and seismic behaviors of historical masonry old mosques. Fatih Mosque, which was converted from a church, constructed in 914 in Trabzon, Turkey, is selected for this purpose. The mosque is being restored. Structural exterior walls of the mosque were made using stone and mortar materials. When the plaster on the walls was removed during the restoration, 12 window openings were found as blind on the exterior structural walls of the mosque. Within the scope of restoration works, it is aimed to open such blind windows. In order to investigate the effects of the window openings on the structural behavior of the mosque, 3D solid and finite elements models of the mosque with and without window openings are initially developed. The experimental dynamic characteristics such as frequency, damping ratio, and mode shapes of the current situation of the mosque, where some windows openings are blind, are determined using Ambient Vibration Testing. Then, the finite element model of the current situation of the mosque is updated using the experimental dynamic characteristics. The static and seismic time history analyses of the updated finite element model with and without window openings are carried out. Structural behaviors of the mosque with and without window openings are compared considering displacement and stress propagations.  相似文献

The Palace of Westminster is in need of urgent, substantial repairs. This provides a ‘window of opportunity’ for change. This essay traces the restoration and transformation (or lack of) that the Palace of Westminster has seen in the last half a century, before assessing its current state, and considering whether parliament is fit for purpose. It provides a ‘long‐view’ understanding of previous missed ‘windows of opportunity’. The essay focuses on drawing insights from history in order to add a depth of understanding to the contemporary issue. An understanding of the preceding renewal and restoration projects enables us, potentially, to avoid some of the problems that have been previously experienced, and finally seize this opportunity to build a parliament which is fit for purpose.  相似文献
