The concept of the first-floor hall was introduced in 1935, but Blair’s paper of 1993 cast doubt on many of those buildings which had been identified as such. Following the recognition of Scolland’s Hall, Richmond Castle as an example of a hall at first-floor level, the evidence for buildings of this type is reviewed (excluding town houses and halls in the great towers of castles, where other issues apply). While undoubtedly a number of buildings have been mistakenly identified as halls, there is a significant group of structures which there are very strong grounds to classify as first-floor halls. The growth of masonry architecture in elite secular buildings, particularly after the Norman Conquest, allowed halls to be constructed on the first floor. The key features of these are identified and the reasons for constructing the hall at this level – prestige and security – are recognized. The study of these buildings allows two further modifications to the Blair thesis: in some houses, halls and chambers were integrated in a single block at an early date, and the basic idea of the medieval domestic plan was already present by the late eleventh century.  相似文献

The Robinson House site is situated within the Manassas National Battlefield Park in northern Virginia. The original Robinson House was constructed in the 1840s and was occupied until 1936 by the same free African-American family. The National Park Service recognizes and interprets the Robinson House since it was part of the Civil War battlefield landscape during the First and Second Battles of Manassas. The original house went through a series of structural additions and alterations in the late 1800s and early 1900s. The house stood until 1993 when arsonists burned it, causing 60% damage to the structure. Today, the east chimney and the stone foundations remain. Amidst the many Civil War monuments at the battlefield park the interpretation of a century of occupation by the Robinson family through the remaining foundations adds meaning and depth to the area's local history. The Robinson House remains symbolize an African-American family's way of life as well as their struggle to survive during Reconstruction and the Jim Crow era. The foundations and site are a steadfast symbol of African-American cultural persistence that has prevailed for over 100 years on a battlefield landscape.  相似文献

In comparison to our understanding of pre‐Islamic occupation and land use on Bahrain, that of the Islamic period has remained less well known. In connection with the building of a visitor centre at the Al‐Khamis Mosque and the planning of an associated heritage trail, renewed archaeological research has taken place in Bilad al‐Qadim, an archaeologically important area of Islamic settlement in the north‐east of the main island of Awal. This has involved excavations in the Abu Anbra cemetery, at Ain Abu Zaydan and at the Al‐Khamis Mosque. The results of these excavations are reported here and these contribute to our understanding of Islamic settlement on Bahrain by supporting the interpretation that Bilad al‐Qadim was the main centre of Islamic settlement in the eleventh–thirteen century AD.  相似文献

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupations in the Pleistocene over vast areas of Arabia. Here we report on the identification of five new Middle Palaeolithic sites from the Nejd of central Arabia and the southern margins of the Nefud Desert to the north. The importance of these sites centers on their diversity in terms of landscape positions, raw materials used for lithic manufacture, and core reduction methods. Our findings indicate multiple hominin dispersals into Arabia and complex subsequent patterns of behavior and demography.  相似文献

There are multiple theoretical accounts of how actors address problems of collective action in policy networks, but the two most prominent hypotheses are the risk and belief homophily hypotheses. The risk hypothesis claims that relational structures (e.g., bridging, bonding) depend on the benefits actors receive from uncooperative behavior, while the belief homophily hypothesis claims that relational ties form around shared policy beliefs. This study incorporates the case of autism and special education policy, a subsystem best characterized by Berardo and Scholz's (2010) conceptualization of a low-risk environment, to test hypotheses about the influence of risk, policy beliefs, and trust on the formation on relational ties in education policy networks. Utilizing data from a 2016 network survey of public and private special education stakeholders in Virginia, results from exponential random graph models provide support for the effects of bridging structures, beliefs related to the medical model of disability, and social trust on strong (collaboration) and weak (information/advice) relational ties in policy networks. The findings reinforce the importance of using policy networks to understand how actors build connections across multiple jurisdictions and policy sectors to mitigate problems of coordination in policy decision making and implementation.  相似文献

ABSTRACT

Professor Roy Ascott developed the Ground Course at Ealing College of Art, drawing on his experience of Basic Design under Victor Pasmore and Richard Hamilton at Newcastle University. Through his reading of Ross Ashby and his friendship with Gordon Pask, Ascott introduced cybernetic theory into his art practice and pedagogy. This essay explores the degree to which Ascott embodied a distinctly British approach to cybernetics.  相似文献
