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.     

New light on early caprine herding strategies from isotope analysis: a case study from Neolithic Anatolia

The measurement of stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopes of caprine bone collagen from the Neolithic sites of Çatalhöyük and Aşıklı Höyük in south-central Anatolia have allowed examination of exploitation and herding practices of sheep and goats. The isotope values from protodomestic caprines at Aşıklı Höyük suggests that these animals were consuming very similar foods to each other and were all confined to the same or similar environments with no access to C₄ plants. At Çatalhöyük, the results show how the caprine management strategy develops from the strategy seen at Aşıklı Höyük into a more varied practice at an early stage as the site grows with an increasing dietary contribution obtained from C₄ plants. No change in diet is isotopically discernible at Aşıklı Höyük. Interestingly, no distinction could be made between the diets of sheep and goats at either site. Therefore, such studies are a useful method of examining the development of early herding or management strategies of caprines in the Near East.     

An Insider's Look into Policy Transfer in Transnational Expert Networks

Much of the recent academic literature on spatial planning in Europe focuses on either cross-national comparison of planning frameworks and planning practices or on transnational and transregional initiatives and their impact on planning in European countries. From those publications, it can be gleaned how similar themes are translated differentially in different national contexts. Although it is also a great source of European integration and harmonization, the phenomenon of the knowledge exchange within transnational expert networks of European planners at the level of cities has received less attention. In this paper, the knowledge exchange among planners in such a network is studied, highlighting the role of “transfer agents” (academic and/or policy experts operating in communities in different policy arenas) in the exchange process. It builds on the insights from existing literature on policy transfer and policy learning, and tries to add a new perspective on this body of literature from an insiders' perspective, i.e. participatory observation. The idea is that policy transfer can be fruitfully approached as a process of knowledge and information transfer between producers, senders, facilitators and recipients. Often this exchange is to a very large extent a process of absorbing appealing labels for policy solutions from the international or national policy levels, and then adopting an interpretation of it suitable to one's own context. The authors try to give meaning to this exchange process by using two mechanisms, i.e. social interaction and conceptual replication. By combining these two mechanisms the authors try to uncover which policy lessons are being transferred among seven European cities that joined the expert network on European sustainable urban development (Pegasus).
