Die Frage nach der Gestaltung von Zuwanderung ist in der Debatte um das Zuwanderungsgesetz vor allem auf diejenigen fokussiert worden, die noch kommen werden. Zugewanderte gestalten unsere Städte und Gemeinden jedoch bereits seit mehr als 40 Jahren aktiv mit: zum einen als Bewohner und Arbeitnehmer, zunehmend aber auch als Investoren und Gewerbetreibende. Und der Blick auf die Prognosen zur Bevölkerungsentwicklung zeigt, daß ihr Anteil an der Gesamtbevölkerung und damit auch ihr Einfluß auf die Stadt- und Wirtschaftsentwicklung weiter zunehmen. Deutlich ist: Zur Gestaltung der Zuwanderung bedarf es mehr als eines neuen Zuwanderungsgesetzes. Zugewanderte müssen die Chancen haben, sich aktiv an der Gestaltung unserer Innenstädte zu beteiligen. Lebenswerte Städte brauchen das Engagement aller Bevölkerungsgruppen. Bisher ist aber die Beteiligung von Zuwanderern bei raumrelevanten Fragestellungen trotz vielfältiger Ansätze immer noch nicht selbstverständlich. Der Bedarf der stärkeren Beteiligung von Zugewanderten besteht daher sowohl von Seiten der Migrantenvertreter als auch von Seiten der Fachverwaltungen. Dabei setzt sich die Planungsphilosophie durch, daß nicht für, sondern gemeinsam mit Zugewanderten geplant werden muß. Vor diesem Hintergrund hat die Stadt- und Regionalplanung Dr. Paul G. Jansen GmbH von 2001 bis 2003 mit Unterstützung des Ministeriums für Städtebau und Wohnen, Kultur und Sport des Landes Nordrhein-Westfalen das Modellprojekt Interkulturelle Stadtentwicklung in den drei Städten Bergkamen, Königswinter und Duisburg durchgeführt. 相似文献

This essay argues that translation in Se questo è un uomo (If This is a Man) (1947), as well as in related pieces, functions for Primo Levi as a key means for claiming and potentially repairing manhood. In its capacity to reposition meaning, translation functions as a powerful vehicle for affirming agency, particularly gendered agency. What emerges in Levi's writings, particularly in Se questo's “Canto of Ulysses” chapter, is the figure of the translator as resistance fighter: the man who uses his intellect, his love of languages and other men, and his desire to communicate in order to combat the assault on humanity perpetrated by Nazism and sustained by its legacy. In this Levi's writing exists on a continuum with the cultural work of the founding members of Giustizia e Libertà and, accordingly, complicates Italy's postwar understanding of partisan activity. Throughout Se questo è un uomo and related works, translation proves a vital if imperfect means for reclaiming manhood and for asserting the possibility of friendship across cultural, regional, ethnic, and gender boundaries. 相似文献

Determination of the source of Spondylus objects is essential for the interpretation of Late Neolithic exchange systems and the social role of shell ornaments. We performed stable isotope analysis combined with cathodoluminescence microscopy study on ornaments (beads, bracelets) made of Spondylus shells excavated at the Aszód-Papi földek archaeological site in Hungary, to define their origin. For comparison Spondylus finds from Neolithic sites of Greece, modern Spondylus shells from the Aegean and the Adriatic, as well as fossil Spondylus and Ostrea shells from the Carpathian Basin were also examined. Oxygen isotope composition of Spondylus finds from Aszód ranges between ?1.9 and 2.1‰ and overlaps with the oxygen isotope range of shell objects from other Neolithic sites. Modern Spondylus shells from the Aegean and the Adriatic show overlapping δ18O values with one another and with the Neolithic objects; while recent shells of the Black Sea clearly are separate isotopically from the Mediterranean ones and most of archaeological artefacts. Spondylus shells from the Aszód site have Mediterranean origin; their source can be the Aegean or the Adriatic. Based on a former strontium isotope study the use of fossil Spondylus shells is excluded as raw material used for ornaments, however, in recent years the use of fossil shells was reintroduced. The shell ornaments from Aszód-Papi földek and the fossil oyster shells collected from the Carpathian Basin exhibit some overlapping oxygen isotope values; however, cathodoluminescence microscopy indicates that the Spondylus objects retained their original aragonite material. Diagenetic calcite, which occurs typically in the fossil shells, was not detected in the ornaments suggesting that the studied objects were made of recent shells. Calcitic parts observed in some Spondylus objects are not related to fossilisation. 相似文献

The recent developments of the economic theory suggest that due attention to territorial context increases efficiency and improves delivery of the policies. This in turn calls for better linkages between spatial and socio-economic efforts. The paper analyses the concept of policy territorialization and proposes policy tools for that purpose. The relevant theoretical models are used, mainly evolutionary economics and new economic geography. The key outcome is a set of territorial keys supposed to enhance territorial approach in developmental policies. Also some plausible ways of making use of those keys are proposed and then tested using Polish territory as a case study. 相似文献

Epistemic communities are an established concept in the study of international relations but can also explain policy change at the domestic level. This article asks why some epistemic communities manage to convince decision makers of their preferred policies while others do not. It suggests that the reason lies in the causal mechanism of epistemic communities' influence on decision makers, mediated by decision makers' demand for expert input. Most epistemic communities scholarship focuses on single case studies where the communities' influence on policy was strong and clear, leading to an overestimation of the groups' influence. To help correct this probable bias, this article compares a successful case of epistemic community influence (health technology assessment in Poland) with an unsuccessful example of the same policy (in the Czech Republic). The juxtaposition allows for unpacking of the necessary parts of the causal mechanism (emergence of an epistemic community, its activity, access to decision makers, and successful suasion) and separating them from the crucial scope condition. Decision makers' uncertainty about the policy issue at hand has traditionally been the key scope condition for epistemic communities but the successful Polish case demonstrates that epistemic communities can be influential even in highly certain areas of routine policymaking, leading to a reconceptualization of uncertainty as policymakers' demand for expert input. Demand can originate from various sources, but any change of it affects individual parts of the causal mechanism, leading to a success or failure of epistemic communities' policy enterprise. 相似文献
