Optimal Spectral Acceleration-based Intensity Measure for Seismic Collapse Assessment of P-Delta Vulnerable Frame Structures

This study proposes an “optimal” spectral acceleration-based intensity measure (IM) to assess the collapse capacity of highly inelastic frame structures vulnerable to the P-delta effect. The IM is derived from the geometric mean of the spectral pseudo-acceleration over a certain period interval. The lower bound period of the averaging interval is related to the mode in which 95% of the effective modal mass is exceeded. The upper bound period is 1.6 times the fundamental period. This IM provides minimum, or close to the minimum, dispersion for frames with different fundamental periods of vibration, or number of stories.     

Ceremonial objects or household items? Non‐destructive μ‐XRD2 and μ‐XRF studies on three Neolithic hematite axes from Qatar

Three small stone axes were collected by the joint Qatari‐German South Qatar Survey Project (SQSP) at two places close to the eastern and western coast of Qatar in autumn 2012. Associated with settlement remains, flint artefacts and pieces of ?Ubaid pottery, the implements have been dated to the fifth millennium BCE. Non‐destructive μ‐XRD² and μ‐XRF analyses could, for the first time, prove the use of hematite as the raw material for the manufacture of these tools in Arabia. The absence of major hematite sources in the region and the special characteristics of hematite — a unique metallic shine of polished pieces and the blood‐red colour that appears during the manufacturing process — suggest the highly symbolic character of these objects.     

Dinosaurier‐Skelette als Kriegsziel: Kulturgutraubplanungen,Besatzungspolitik und die deutsche Paläontologie in Belgien im Ersten Weltkrieg

The paper deals with the unnoticed and sweeping activities of German scientists and university disciplines in the context of German occupation policy and plannings of plundering cultural assets as war pillage during the First World War. It exemplarily shows the case of palaeontologists in occupied Belgium: Their main project was the famous excavation site of skeletons of the dinosaur Iguanodon in the small town Bernissart. After a new excavation between 1915 and 1918 they planned, with the support of occupation authorities, the transportation of dinosaur skeletons into German natural history museums and collections as war pillage.     

Laser scanning for conservation and research of African cultural heritage sites: the case study of Wonderwerk Cave,South Africa

The ‘African Cultural Heritage and Landscape Database’ project, initiated and directed by the senior author and administered by Aluka (www.aluka.org), is aimed at the creation of a digital library of spatial and non-spatial materials relating to cultural heritage sites in Africa. The archaeological site of Wonderwerk Cave (South Africa) is one of the 19 sites documented to date using laser scanning, conventional survey, digital photogrammetry and 3D modelling. To date, it is one of the few archaeological caves worldwide to be fully scanned. This paper explores the different uses to which the spatial data derived from this cave have been, or will be, put – for historical and educational purposes, scientific research and site conservation and development.     

Investigation of past archaeological landscapes using remote sensing and GIS: a multi-method case study from Mount Ida,Crete

Spatial analysis in geoarchaeological applications can be improved by implementing a wider set of geoecological parameters, in order to provide more precise results. The aim of the paper is to show how geoscientific ground-truth and techniques can be adopted for detailed archaeological studies using a comprehensive set of environmental variables that might have influenced ancient settlement patterns. The project focuses on spatial patterns of archaeological sites as well as Bronze Age communication paths in Central Crete by applying a multi-method approach (surveying, remote sensing, DEM analysis, least-cost analysis, candidate site detection, predictive modelling, etc.). In contrast to conventional archaeological GIS applications this enhanced strategy offers promising prospects regarding landscape and settlement modelling.     

Reformation(en) und Wissenschaft(en). Einführung in das Tagungsthema

Based on a brief historiographical survey, the article aims at tracing some intellectual relationships between early modern science and the protestant Reformation (or the various individual reformations underlying it). Besides the mere structural analogies of the two reform movements and their common debt to Renaissance humanism, common elements such as the new reading of texts and the new role of the individual, but also the philosophical link between voluntarism and the notion of natural law, are discussed. However, the ambiguous attitude towards natural knowledge and the wide variety within the European protestant movement ask for a much closer look into the relationships between science and the Reformation than has been hitherto been achieved.
