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.  相似文献

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.  相似文献

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ13C values surprisingly similar to those seen in marine fish. We propose a model, based on δ13C and δ15N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.  相似文献

In this paper I examine the development of a particular kind of grey stoneware called kamuiyaki which was produced and traded within the Ryukyu Islands, southwestern Japan, in the eleventh to fourteenth centuries. The wares themselves, their chronology, and archaeological context are discussed. The kilns represent the first enterprise in the islands in which a commodity was made for exchange on a substantial scale. The establishment of the kilns in a remote area, with technological borrowing from both Japan and Korea, reflects social and economic trends of the beginning of the Medieval Period in Japan. Greyware production, circulation, and consumption, reconstructed from recent excavations, shows a political economy capable of fostering the development of small states on the island of Okinawa in the thirteenth and fourteenth centuries.  相似文献

Ethnoarchaeology appears nowadays as a poorly formulated field. However, it could become a real science of reference for interpreting the past if it was focused upon well-founded cross-cultural correlates, linking material culture with static and dynamic phenomena. For this purpose, such correlates have to be studied in terms of explanatory mechanisms. Cross-cultural correlates correspond to those regularities where explanatory mechanisms invoke universals. These universals can be studied by reference to the theories found in the different disciplines they relate to and which are situated outside of the domain of archaeology. In the domain of technology, cross-cultural correlates cover a wide range of static and dynamic phenomena. They allow the archaeologist to interpret archaeological facts—for which there is not necessarily analogue—in terms of local historical scenario as well as cultural evolution. In this respect, it is shown that ethnoarchaeology, when following appropriate methodologies and focussing on the universals that underlie the diversity of archaeological facts, does provide the reference data needed to climb up in the pyramid of inferences that make up our interpretative constructs.  相似文献

Level IV of Molodova I, an open-air Middle Paleolithic site in the Ukraine has been described by some researchers as a possible source of evidence for early symbolic behavior. We examined bone objects from this layer that were identified by Ukrainian researchers as exhibiting possible Neandertal produced engravings including two anthropomorphic figures. While we have determined that there is no evidence of symbolic activity at Molodova I, the database we have created, with its systematic recording of traces left by taphonomic agents on faunal remains, provides a better understanding of the overall site taphonomy.  相似文献
