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

In this contribution we discuss the process of feedback and dissemination that we adopted following research with children affected by AIDS in southern Africa. We outline our reasons for engaging in detailed feedback and dissemination, distinguishing between active or passive processes and discuss the participatory methods we adopted. Through our reflections we consider feedback as an obligation to participants and dissemination as a potential agent of social change. In addition we evaluate the effectiveness with which we were able to truly incorporate the voices of young people in our dissemination and relinquish control of the outcomes to make them available for action among policy-makers. In conclusion we highlight that active dissemination, although not able to guarantee that research recommendations will be acted upon, at the very least opens dialogue and enhances understanding among those able to implement action.  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

Despite collaborative governance's popularity, whether collaboration improves policy performance remains uncertain. This study assesses the link between collaborative decision making and licensed environmental management protocols in the Federal Energy Regulatory Commission's (FERC's) process for licensing hydropower facilities in the United States. Using results from a previous study of FERC relicensing (Ulibarri, forthcoming), one high‐, one medium‐, and one low‐collaboration case were selected. Using documents including meeting minutes, public comments, and issued licenses, I assessed collaboration and license outputs, then conducted process tracing to examine whether and how differences in collaboration produced differences in license quality. High collaboration resulted in jointly developed and highly implementable operating regimes designed to improve numerous resources, while low collaboration resulted in operating requirements that ignored environmental concerns raised by stakeholders and lacked implementation provisions. These results support the hypothesis that collaboration can improve environmental outcomes, revealing the pragmatic value of collaboration.

The number of phytolith studies has increased steadily in the last decades in palaeoecological as well as archaeological research, and phytolith analysis is currently recognised as a proper area of expertise within archaeobotany. This has led towards a strengthening in the standardisation of the different steps involved in analysis; e.g. sampling strategies, laboratory extraction or processing of plant material/soils for the creation of reference collections. In spite of this, counting procedures remain one of the areas that could be further developed. The aim of this paper is to assess representativeness of phytolith count size in archaeological samples and specifically to assess whether an increase in total number of individuals counted influences the number or distribution of morphotypes observed. Two statistical tests are performed to evaluate the representativeness of count size: phytolith sum variability analysis (PSVA) and morphotype accumulation curve (MAC). The analyses show the relationship among the number of counted phytoliths, the variability (that is, the number of different morphotypes identified) and the stabilisations of the MACs. Results allow us to support the standard count size in phytolith studies, which ranges from 250 to 300 particles. Together with a quick scan, this strategy should produce a precise and clear phytolith assemblage for archaeological studies.  相似文献

Mexico’s National Institute of Anthropology and History established an ethical program for the protection and research of the country’s underwater cultural heritage (UCH). Its Vice-Directorate of Underwater Archaeology trains archaeology and conservation students, participates in national and international initiatives regarding UCH, and develops multidisciplinary projects in maritime and continental waters. During negotiation of the UNESCO Convention, the Latin American and Caribbean Group united in a strong voice and contributed to its adoption in 2001; in 2006, Mexico ratified the Convention. This article highlights Mexico’s adoption of the 2001 UNESCO Convention as a case study, to stimulate all countries to ratify the convention and to cooperate in protecting the world’s UCH.  相似文献
