Rock engravings in the Wadi el-Barramiya,Eastern Desert of Egypt

This paper describes new rock art sites in the region east of Idfu, where at least 50 sites with several thousands of petroglyphs offer huge potential for future research. Site ET-A/WB 4 provides the largest representation of a boat yet discovered in the Eastern Desert; it is part of a scene extending over about 10 m of rock with boats, animals and human figures in procession. This scene and another one from site ET-A/WB 5 can be dated to the transition from the prehistoric to the dynastic periods. All sites in the Wadi el-Barramiya are endangered due to their location near a main road used by construction works and visitors.

Résumé Dans cet article quelques sites à gravures rupestres récemment découverts dans la région à l'est d'Idfu sont décrits. Une cinquantaine de ces sites avec des milliers de pétroglyphes présentent un potentiel énorme pour les recherches futures. Le site ET-A/WB 4 nous donne la représentation d'un bâteau la plus grande connue jusqu' à présent dans le désert oriental d'Egypte. Cette représentation cependant ne constitue qu'un morceau d'un tableau qui se prolonge sur environ 10 m de la surface rocheuse avec des bâteaux, des animaux et des formes humaines en cortège. Ce tableau ainsi qu'un autre du site ET-A/WB 5 peut être situé chronologiquement à la transition de l'époque préhistorique et l'époque dynastique. Tous les sites du Wadi el-Barramiya sont menacés en raison de leur proximité d'une grande route fréquentée par les touristes et aussi par les travaux publics.

     

Regional economies,interactive television and interorganizational networks: A case study of an innovation network in Baden‐Württemberg

This paper explores attempts to establish a network of firms and organizations to develop the multimedia industry at a regional level. The paper sets out its review in the context of the regional economy, and then details the nature of the networking process under investigation. An evaluation of networking in this context is provided, based on detailed empirical research. Lessons are drawn from the experiences of seeking economic modernization through organizational networks.     

Phytolith-rich layers from the Late Bronze and Iron Ages at Tel Dor (Israel): mode of formation and archaeological significance

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.     

The construction of an ideological curriculum: The study of Emunah in the Har Hamor Yeshiva

Beginning in 1997, the Har Hamor Yeshiva, a leading Jerusalem-based institute for Torah learning, has become the center of a unique stream of thought in religious Zionist philosophy. This article examines how religious Zionist yeshivas have developed an educational curriculum that translates theological beliefs and values into political action. The article seeks to evaluate to what extent this ideology and curriculum will be able to survive in a political reality in which the rift between religious and secular Zionism is constantly increasing.     

A multi-layered prehistoric settlement structure (tell?) at Niederröblingen,Germany and its implications

At least 15 settlement layers, deposited above each other from the early Neolithic (ca. 5300 cal BC) until Roman Imperial Times (ca. 400 cal AD), have been discovered at Niederröblingen, Germany. Constituting the longest duration of prehistoric settlement in central Europe so far known (ca. 4000 yrs), the site is thought to represent the first multi-layered settlement mound (tell?) north of the Alps. This implicates that the occurrence of settlement mound is not limited to the circum-Mediterranean area. The detailed chronology, based on archaeological, radiocarbon and OSL dating and supporting a Bayesian model, shows one clear occupational gap (early Neolithic) and a possible hiatus (Roman Times). Erosion phases of the settlement mound and the deposition of alluvial sediments (since Roman Imperial Times) in the surroundings resulted in an almost complete disappearance of the mound from the recent scenery. Being difficult to detect, similar sites might be present, undetected, in central Europe. Their discovery and study would enable the precise reconstruction of the settlement history as well as of the prehistoric man–environmental interactions at a high resolution.     

Geoarchaeological studies on Roman time harbour sediments in Cologne — comparison of different OSL dating techniques

Due to the construction of a new North-South subway in Cologne, Roman time harbour sediments were exposed and were sampled for luminescence dating. A very good independent age control was given by the precise knowledge of the chronology of Roman activity and by radiocarbon ages of charcoal samples. Hence, different methodological approaches within luminescence dating were applied for Holocene heterogeneously bleached fluvial samples and were compared to the known ages. For one sample, optically stimulated luminescence (OSL) dating was applied to coarse-grained quartz using a single aliquot regenerative-dose (SAR) protocol. After D_e-measurements, different statistical approaches were tested (i.e. arithmetic mean, median, minimum age model, finite mixture model, leading edge method and the Fuchs and Lang approach). It is demonstrated that the Fuchs and Lang approach along with the leading edge method yielded the best matching OSL ages with respect to the known ages.     

Performance tests using the Lexsyg luminescence reader

This study presents test measurements on a Lexsyg luminescence reader, acquired by the Giessen luminescence group. The reader is of the type Standard, hence designed for routine determination of palaeodoses using quartz or K-feldspars. The tests include measurements of the stimulation powers, preheat temperatures, OSL- and TL-curves, as well as dose recovery tests and calibration measurements using highly sensitised calibration quartz. A comparison of D _e values determined using a Lexsyg reader with single grain D _e-values, which have been previously obtained on a Risø reader, is also presented. The results imply that the Lexsyg reader is a highly reliable measurement device with high reproducibility, yielding instrumental uncertainties of around 0.3%.
