The magic of early medieval ritual

Whether, and how, we ought to study early medieval rituals has been much debated recently, including in the pages of this journal by Geoffrey Koziol and Philippe Buc. This paper is intended as a contribution to this debate, and argues that rituals' written or spoken interpretations are not a simple rendering of the ritualized actions' 'meanings' in words and must therefore be analysed separately, not conflated with the possible effects of performance. Ritualized acts thus had two loci: the short-term experience of the embodied performance, and the long-term struggle over interpretation in speech and writing, both of which need to be explored with appropriate methodologies. Whilst the textuality of our sources thus needs to be taken seriously, it is proposed that we can also say something about the possible or even probable characteristics of early medieval ritualized acts as the medium of bodily postures and gestures used for demonstrative public interations between power holders.

Auf den Spuren einer Wachstumsbranche

Zusammenfassung Immer mehr Geographinnen und Geographen sind in der Consultingbranche t?tig. Dipl.-Geogr. Dr. Manfred Miosga ist auf diesem Markt seit einigen Jahren selbstst?ndig. Zusammen mit seinem Kollegen und Firmengründer Wolfgang Grubwinkler ist er Vorstand der „IDENTIT?T und IMAGE Coaching AG“ mit Sitz im niederbayrischen Eggenfelden. Die Firma hat seit 2001 die Betriebsform einer kleinen Aktiengesellschaft; im Aufsichtsrat führt Prof. Dr. Günter Heinritz von der Technischen Universit?t München den Vorsitz. Das Unternehmen besch?ftigt sieben Mitarbeiter, au?erdem bietet es gelegentlich Praktikumspl?tze. Dr. Manfred Miosga sprach mit Dipl.-Geogr. Ute Christina Bauer über seine eigenen beruflichen Erfahrungen und die Chancen von Geographinnen und Geographen in der Beraterbranche.     

„Geo“ erlebbar machen

Zusammenfassung  Geoparks sind ausgewiesene R?ume, in denen die Bedeutung geologischer und geomorphologischer Prozesse für die Gestalt der Erdoberfl?che, für die Verteilung natürlicher Ressourcen, aber auch für die Landnutzung sowie die Wirtschafts- und Kulturgeschichte bewusst und erlebbar gemacht wird. Für Deutschland hat es die GeoUnion übernommen, sogenannte Nationale GeoParks zu begutachten und zu zertifizieren. Mit der Geologin Dr. Ulrike Mattig, Vorsitzende der Expertengruppe für Nationale GeoParks Deutschland, sprach Dipl.-Geogr. Ute Christina Bauer über das Geopark-Konzept und seine Umsetzung.     

From deep to shallow fluid reservoirs: evolution of fluid sources during exhumation of the Sierra Almagrera,Betic Cordillera,Spain

The combination of structural, geochemical and palaeotopographic data proves to be an efficient tool to understand fluid transfers in the crust. This study discriminates shallow and deep fluid reservoirs on both sides of the brittle–ductile transition under an extensional regime and points out the role of major transcurrent fault activity in this palaeohydrogeological setting. Palaeofluids trapped in quartz and siderite–barite veins record the transfer of fluids and metal solute species during the Neogene exhumation of the Sierra Almagrera metamorphic belt. Ductile then brittle–ductile extensional quartz veins formed from a deep fluid reservoir, trapping metamorphic secondary brines containing low‐density volatile phases derived from the dissolution of Triassic evaporites. During exhumation, low‐salinity fluids percolated within the brittle domain, as shown by transgranular fluid inclusion planes affecting previous veins. These observations indicate the opening of the system during Serravalian to early Tortonian times and provide evidence for the penetration of surficial fluids of meteoric or basinal origin into the upper part of the brittle–ductile transition. During exhumation, synsedimentary transcurrent tectonic processes occurred from late Tortonian times onwards, while marine conditions prevailed at the Earth's surface. At depth in the brittle domain, quartz veins associated with haematite record a return to high‐salinity fluid circulation suggesting an upward transfer fed from a lower reservoir. During the Messinian, ongoing activity of the trans‐Alboran tectono‐volcanic trend led to the formation of ore deposits. Reducing fluids caused the formation of siderite and pyrite ores. The subsequent formation of galena and barite may be related to an increase of temperature. The high salinity and Cl/Br ratio of the fluids suggest another source of secondary brine derived from dissolved Messinian evaporites, as corroborated by the δ³⁴S signature of barite. These evaporites preceded the main sea‐level drop related to the peak of the salinity crisis (5.60–5.46 Ma).     

The effect of vacant building demolitions on crime under depopulation

The costs of demolishing a vacant building are often justified on the grounds of crime reduction. I explore this claim by estimating the spatial and temporal effects of demolitions on reported crime in the city of Saginaw, Michigan. To do so, I estimate a model that uses within‐block group variation to compare crime after a demolition occurs to before the permit for that demolition was issued. Results indicate that demolitions reduce crime by about 8 percent on the block group in question and 5 percent on nearby block groups, with the largest impact concentrated one to two months after the demolition occurs.     

HLO1‐south: An Early Neolithic site in Wadi al‐Hilo (Sharjah,UAE)

Site HLO1 (Sharjah, UAE), situated in a particularly favourable geographical position, has provided an extraordinary range of anthropogenic radiocarbon dates, spanning before 8000 to Zero BCE. The Neolithic is represented by finds from the eighth to the fifth millennium BCE. Apart from the dated fireplaces, however, there are almost no typical artefacts of this period. Small stone structures appear to have been early Neolithic graves. A middle Neolithic grave consisted of a large rounded stone heap which was reused as a grave during the Late Bronze Age. The site is interpreted as a campsite of nomadic herders, used throughout the Neolithic period. After a break in the fourth millennium BCE, the site became a Bronze Age smelting site which continued to be settled until the Late Iron Age.     

Experimental examination of animal trampling effects on artifact movement in dry and water saturated substrates: a test case from South India

This paper presents the motivation, procedures, and results of an experiment that examines short episodes of animal trampling in dry and water saturated substrates in South India. While horizontal artifact displacement was similar to that modeled by other trampling experiments, vertical artifact displacement in water saturated substrates was greater than any reported experiment to date. The toolstone used in this experiment, a silicious limestone, exhibited minimal damage after trampling. Artifact inclination patterning appeared to be a potentially diagnostic middle-range marker of trampling in water saturated substrates. Given the abundant number of Paleolithic sites that are located on flat, open surfaces near water-bodies, or experience monsoonal climatic regimes, we propose that future excavations should measure artifact inclination on a regular basis.     

Persistence and Change of Regional Industrial Activities: The Impact of Diversification in the German Machine Tool Industry

The paper investigates the stability and change of regional economic activities in the long run. As the unit of analysis, we selected the machine tool industry in West Germany for the years 1953–2002. We spot a strong variance in the activities between different regions. These differences are relatively stable over time, and the regional activities are rather path-dependent. Nevertheless, the paper also identifies changes in the level of activities. As the main driving factors for these developments, we examine the effect of changing regional degrees of diversification over time. We find that those regions which generally broaden their scope of activities have a higher likelihood to grow than regions which are specializing. Furthermore, diversification into totally new technological and product fields is only beneficial under specific circumstances based on technological and market developments. Hence, in most cases, a broad diversification is superior to one focusing on new state-of-the-art technological fields.
