„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.     

In the Canine Archives of Sex: Radclyffe Hall,Una Troubridge and their Dogs

How does attention to dogs open up understanding of the queer, and more specifically, the Sapphic, past? This article examines the forgotten enmeshments of lesbian and pedigree dog subcultures in 1920s England. It takes as its case study one of the best-known couples of Sapphic modernity, Radclyffe Hall and Una Troubridge, and their dachshunds, Wotan and Thorgils. Bringing into dialogue scholarship on queer, trans and animal history, it traces the historical footprint of the dogs and considers how what this article calls the ‘canine archive of sex’ – a wide range of documents including show catalogues, newspaper reports, fiction and scientific writing – adds to understanding of the complexities of modern Sapphic history. Sapphic here is used to denote relationships between people assigned female at birth, some of whom may have transed gender norms and expectations. The article argues that the records of Hall's and Troubridge's involvement in the world of dog breeding expand understanding both of Sapphic modernity specifically and the intersections between histories of sexuality and gender and animal history more broadly. They reveal how gender norms, class privilege and racialised practices converged in modern pedigree culture, shaping canine–human relationships as well as the queer subcultures that formed around them.     

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.
