Re-evaluating the Neolithic: The Impact and the Consolidation of Farming Practices in the Cantabrian Region (Northern Spain)

Research projects undertaken in the Cantabrian region since 1980 have produced new, high-quality information about the neolithisation process(es) in this area. It is now necessary to review this archaeological information and test the main hypotheses put forward to explain it. This paper presents an update on the archaeological evidence (sites, chronological dates, archaeozoological, archaeobotanical and technological information) for the early Neolithic in the Cantabrian region. It summarizes recent research on neolithisation in the region, and assesses the impact of this process during the early Neolithic, and its later consolidation. Although the available information is still incomplete, it is now possible to identify the focal point of the introduction of elements characteristic of the Neolithic way of life in the region. Current evidence suggests that it is in the eastern sector, where the earliest arrival of domesticates and new technologies such as pottery has been attested. The existence of continuities—such as sustained reliance on hunting and gathering and the coexistence of old and new funerary rites—suggests the persistence of native populations, which gradually participated in the neolithisation process after an ‘availability phase’.     

Performance-based Seismic Design of a Pendulum Tuned Mass Damper System

The study implements the performance-based analysis and design methodology to assess the seismic vulnerability of a coal-fired power plant and to optimally design its equivalent pendulum-type tuned mass damper system such that the direct losses are minimized. A building-specific total loss ratio is developed to link the component level losses with the total repair cost of the original structure. The optimal system configuration is finally derived for cases with the minimum loss. The study demonstrates a systematic way of achieving the optimal pendulum-type tuned mass damper design with considerations of uncertainties in earthquake inputs and the combined component level damages.     

Zukunft Ruhr 2030

Zusammenfassung  Regionale Entwicklungsstrategien werden in der Regel ohne substanzielle Beteiligung der Wirtschaft entwickelt. Das war im Projekt „Zukunft Ruhr 2030“ anders. Hier hat der „Initiativkreis Ruhrgebiet“, die Vereinigung gro?er Unternehmen in der Metropolregion Ruhr, Entwicklungsperspektiven für die Region aus Sicht der Wirtschaft entworfen. Sechs führende Unternehmensberatungen haben in Zusammenarbeit mit Experten aus Wissenschaft und Wirtschaft verschiedene Themenfelder untersucht, eine Vision entwickelt und daraus eine Entwicklungsstrategie für die kommenden Jahre abgeleitet.     

Der „Mitteleuropäische Kristall“ – zwischen „Blauer Banane“ und „osteuropäischem Pentagon“

Der deutsch-tschechische Grenzraum liegt gewisserma?en in einer Sandwich-Position zwischen verschiedenen europ?ischen Makroregionen; auf europ?ischer Ebene wird er bislang eher als Verbindungselement wahrgenommen. Seine innere Struktur ist von einer relativ geringen Besiedlungsdichte und ausgepr?gten Stadt-Land-Unterschieden gekennzeichnet. Im Frühjahr 2006 gründeten die beiden nationalen Regierungen eine deutsch-tschechische Arbeitsgruppe für Raumentwicklung. Der Artikel skizziert, welche Ziele und Erwartungen damit verbunden werden und welche Funktionen ein solches Gremium übernehmen kann. Dazu wird zun?chst die Ausgangssituation dieses Raumes skizziert. Abschlie?end wird das m?gliche Leitbild des „Mitteleurop?ischen Kristalls“ vorgestellt.     

What can pollen grains from the Terracotta Army tell us?

The provenance of more than 2200-year-old terracotta warriors and horses in the Qin Shihuang Mausoleum is still a mystery, even though some researchers have inferred that the terracotta figures were produced near the mausoleum. The sporomorphs (pollen and spores) extracted from terracotta fragments of a warrior and a horse and compared with those obtained from soil samples from the Qin Dynasty layer in Pit No. 2 of the Qin Shihuang Mausoleum indicate that the pollen spectrum from the terracotta horse is different from that of the warrior, but similar to the local soil samples. Herbaceous pollen was dominant in the warrior sample, while arboreal pollen predominates in the horse and soil samples. Palynological evidence suggests that the terracotta horses were produced at a locality near the mausoleum, while the warrior came from a site which was further afield.
