An eighth century hoard from Eastern Saudi Arabia

Editor's note. The article published here was completed on October 22, 1966. Although never published before, copies have long been on file in both the Dept. of Coins and Medals in the British Museum, and at the American Numismatic Society. The basic content of the hoard was reported on in Coin Hoards 1 (1975). In 1986, Robert W. Morris revised the text of his paper and sent me a copy. After the founding of Arabian Archaeology and Epigraphy , I asked him whether he would like to publish the paper, a suggestion to which he responded enthusiastically. On August 25, 1990, just ten days after I sent him a letter about my plans for preparing his text for publication, Robert W. Morris died from complications of myeloma. An avid amateur numismatist for many years, Morris was interested in the pre-Islamic and Islamic coinage of northeastern Arabia (where he had lived and worked for Aramco) right up until his death. It is hoped that, while there may be certain details in the paper which professional numismatists might wish to correct, the body of material presented here will be of interest to a wide audience of scholars concerned with the late pre-Islamic and early Islamic periods in eastern Arabia.     

THE SCIENTIFIC IDENTIFICATION OF ARCHAEOLOGICAL JET-LIKE ARTEFACTS

Jet has been widely used in the past for jewellery but was just one of a range of black lithic materials employed. When worked into small objects these materials can be visually indistinguishable, yet discrimination is important because of the restricted occurrence of jet. X-ray fluorescence (XRF) is a rapid non-destructive discriminatory technique, but not all samples are clearly classified, and inhomogeneity may pose problems. A reassessment of the use of XRF is reported. Other techniques considered include electron spin resonance, infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, scanning electron microscopy and X-radiography. These were tested on geological materials to define an effective methodology for archaeological material. The recommended approach is a combination of XRF and X-radiography, although preliminary Fourier transform infrared results showed promise. The X-ray techniques were tested on Romano-British assemblages from Catterick and Stanwick.     

FROM THE ECONOMIC TO THE POLITICAL: REGIONAL PLANNING IN WEST GERMANY

The resolution of regional disparities within the Federal Republic of Germany entails a complex redistributive process. Regional assistance policies initiated as wartime relief measures have, over time, incorporated classical incentive programs and revenue-sharing. Revenue transfers among the three levels of government are dynamic, arising from changes in the socioeconomic and political environment. Much of the spatial effect of regional policies is overshadowed by more extensive sectoral benefits.
La détermination des inégalités régionales au sein de la République fédérale allemande fait appel à un procédé complexe de redistribution. Des politiques d'aide régionale, introduites comme des mesures de secours en temps de guerre, sont devenues avec le temps des programmes classiques d'incitation et de partage des reVenus. Les transferts de revenu entre les trois niveaux de gouvernement constituent un mécanisme dynamique répondant aux changements dans le milieu socioéconomique et politique. L'influence spatiale résultant des politiques régionales est en grande partie éclipsée par l'expansion des avantages sectoriels.     

Libya and Syria: R2P and the spectre of the swinging pendulum

This article examines recent UN Security Council deliberations over events in Libya and Syria and in particular assesses the extent to which Council members sought to justify their positions and voting behaviour by reference to the ‘Responsibility to Protect’ (R2P). It shows how limited invocations of R2P were with regard to Libya, before proceeding to demonstrate how, somewhat paradoxically, R2P‐sceptics such as Russia and China subsequently drew upon concerns over the manner in which NATO implemented its UN‐mandate in Libya to cast doubts over R2P during debates over Syria. Contemplating the implications of the Libyan and Syrian cases for the future of R2P, the article concludes by arguing that the concept's international standing can best be preserved through the excision of its most coercive elements; R2P should be reconstituted as a standard of acceptable sovereign behaviour and a mechanism geared towards the provision of international guidance and support, while decisions over coercive military intervention, inevitably infused with considerations of strategic interest, should be made outside the R2P framework.     

Pattern formation during healing of fluid-filled cracks: an analog experiment

The formation and subsequent healing of cracks and crack networks may control such diverse phenomena as the strengthening of fault zones between earthquakes, fluid migrations in the Earth's crust, or the transport of radioactive materials in nuclear waste disposal. An intriguing pattern-forming process can develop during healing of fluid-filled cracks, where pockets of fluid remain permanently trapped in the solid as the crack tip is displaced driven by surface energy. Here, we present the results of analog experiments in which a liquid was injected into a colloidal inorganic gel to obtain penny-shaped cracks that were subsequently allowed to close and heal under the driving effect of interfacial tension. Depending on the properties of the gel and the injected liquid, two modes of healing were obtained. In the first mode, the crack healed completely through a continuous process. The second mode of healing was discontinuous and was characterized by a 'zipper - like' closure of a front that moved along the crack perimeter, trapping fluid that may eventually form inclusions trapped in the solid. This instability occurred only when the velocity of the crack tip decreased to zero. Our experiments provide a cheap and simple analog to reveal how aligned arrays of fluid inclusions may be captured along preexisting fracture planes and how small amounts of fluids can be permanently trapped in solids, modifying irreversibly their material properties.     

The Chapter-House of St Albans Abbey: Reconstructing its 15th-Century Vault

Before the 1978 excavation of the chapter-house site directed by Martin Biddle and the late Birthe Kjølbye-Biddle, nothing was known about the 15th-century building, beyond the brief documentary references in the Register to its remodelling during the second half of the century in the time of abbots John of Wheathamstead and William Wallingford. However, the exceptional quantity of late Gothic masonry fragments uncovered during the excavation has made it possible to attempt to reconstruct features of its design, particularly the vaulting, and has transformed our knowledge of this important building. This article reviews the information derived from the study of the fragments of the vault, assesses its significance in the development of late Gothic vaulting, and speculates on the identity of its designer.     

Negotiating the production of space in Tl'azt'en territory, Northern British Columbia

Societies produce the space in which they operate through social practices that visualize, administer, and use lands and resources. Because Native peoples have held relatively little political power, their ability to influence the production of space has received little attention. Yet the superimposition of Euro‐Canadian social practices onto Native spaces rarely erased native spatiality, but rather created a territory made up of shared and hybrid spaces which resulted from the interaction of Native and Euro‐Canadian societies. This paper suggests that the social processes involved in the production of space are perhaps most visible when two parties are negotiating the allocation and management of lands and resources. In the 1970s the Tl'azt'en engaged in negotiations over the construction of a railway through their territory. Through the negotiations Tl'azt'en social and economic goals were inscribed to a significant degree in the spatial organization of the territory. Like current treaty negotiations, the 1970s negotiations involved compromises by both parties, and resulted in the creation of new hybrid social spaces which reflected the goals and strategies of both groups. Les sociétés produisent l'espace dans lequel elles opèrent à travers des pratiques sociales qui visualisent, administrent et utilisent les terres et les ressources. Parceque les peuple Natifs ont eu relativement peu de pouvoir politique, leur capacitéà influencer la production de l'espace a reçu peu d'attention. Cependant, l'imposition de pratiques sociales Euro‐Canadiennes sur les espaces Natfs a rarement effacé la spatialité indigené, mais a plutôt crée un territoire composé d'espaces partagés et hybrides, résultat de l'intéraction des sociétés indigènes et Euro‐Canadiennes. Cet exposé suggère que les procédés sociaux impliqués dans lá production de l'espace sont peut‐être plus visibles quand deux partis négocient l'allocation et la gestion des terres et des ressources. Dans les années 70, le peuple Tl'azt'en s'est engagé dans des négociations au sujet de la construction d'un chemin de fer à travers leur territoire. Dans ces négociations, les buts sociaux et économiques du Tl'azt'en furent inscrits à un degré significatif dans l'organisation spatiale du territoire. Comme les présentes négociations de traité, les négociations des années 1970 ont impliqué des compromis par les deux partis, et ont résultéà la création de nouveaux espaces sociaux hybrides qui reflétaient les buts et stratégies des deux groupes.
