A new generation of greenways has emerged in recent years, the most ambitious of which are nationwide, interconnected networks of multi-use, multi-purpose greenways and trails, clustered under a single national vision. However, because these initiatives have been the focus of so few research studies, opportunities to glean lessons from their planning and implementation have been limited. This paper contributes to addressing this knowledge gap by presenting a comparative account of two networks, the Trans Canada Trail in Canada and Sendero de Chile in Chile. Using document analysis and interviews with officials closely involved in their development, the evolution of both networks is documented over time, emphasizing similarities and differences related to their planning and implementation. Both initiatives have faced significant challenges in reaching their connection goals and have availed themselves of a diverse range of opportunities and strategies to advance their agendas. A simple model of a virtuous cycle is proposed to highlight the positive feedback—between political and public support, sustained funding, partnership development, accessibility for urban residents, and connectivity of the network—generated by sustained network expansion over time. It is hoped that the insights offered from this analysis may offer guidance to inform the development of similar scale projects elsewhere.  相似文献

Archaeological wood, as most of natural materials, is slowly decomposing on the archaeological site due to various biological factors. Rapid and accurate estimation of the degradation level is extremely important for optimal restoration and conservation. The goal of this research was to verify the effectiveness of Fourier transform near infrared (FT-NIR) spectroscopy for archaeometry. The important advantage of the NIR spectroscopy is its accuracy, simplicity and ability to perform very high number of tests without needs of any destruction to the workpiece. Five oak pieces of the archaeological wood collected from waterlogged sites in Poland have been used. Cellulose and lignin contents, as well as crystallinity and the degree of polymerization were measured with standard reference methods and compared to the contemporary wood. The near infrared spectra represent all the physical/chemical changes of the wood due to waterlogging. This technique was successfully validated in rapid estimation of the cellulose and lignin contents. The method explored in this research might be a novel tool assisting experts in evaluation of the degradation state of archaeological and historical wooden materials.  相似文献

Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts.Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animal’s origin.From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland.  相似文献

How do we account for the reinforcement of identity particularisms despite transnational integration? This paper addresses the question by comparing two ethnolinguistic groups, Silesians and Kashubs in Poland. It is argued that in order to obtain state protection and tools to develop and survive, ethnic entrepreneurs adjust to institutions and discourses. Census politics, state laws' elaboration, transnational institutions represent openings to which groups adjust by reframing identity claims. In doing so, they re‐imagine and reinforce their communities. Following Rogers Brubaker, group‐making is presented as an eventful process where ethnic elites invest identity categories with groupness by taking advantage of opportunity windows at hand. Further, tracing changing political opportunities, strategic adjustments and groups' boomerang effect bid, the paper embeds identity groups within the social movement literature.  相似文献

This article presents an inquiry into which tacit differences are relevant for how people make sense of encounters with others in urban settings, and how, if at all, they are translated into ethnic categories understood as ‘basic operators’ in everyday life. Drawing from our interviews with twenty Polish mothers living in Berlin and Munich, we argue that what our research participants distinguish as ‘typically Polish’ or ‘typically German’ is not necessarily connected to some ethnically specific ways of working or mothering, but, rather, significantly structured by locally specific forms of neoliberalism. By asking what kind of difference becomes understood as ethnic difference and how this process of demarcation occurs, this article adds to the strand of intersectional approaches that theorise the notion of difference, recognise heterogeneity of individual categories and render them suspect.  相似文献

Michael Haneke’s film The White Ribbon (2009) narrates violent attacks that disrupt the cyclical life of a German village in 1913–14. The narrator frames the violence as a study of the origins of fascism: the alleged perpetrators are children, who rebel against the disciplinary powers of patriarchal authority. Coming to maturity during World War I, they will have become the generation of Nazism’s followers. In contrast to psycho-historical readings of The White Ribbon as a cinematic exploration of the causal relationship between the authoritarian formation of the juvenile subject and her susceptibility to fascism’s redemptive illusions, I propose an anti-psychological interpretation of the film. This reading seeks to understand The White Ribbon in terms of Haneke’s aesthetic and formal choices, which underpin his notion of “ethical spectatorship.” I argue that the film offers a dual metaphorical construction of the nexus between memory and the cinematic image, and of the mnemonic and affective aspects of the history of violence. Haneke forges a link between the European attitude to its history of fascism and its ongoing politics of exclusion, arising from its covert fascist desire for the unified self. The significance of The White Ribbon in the ongoing debate on history/memory thus lies in its critique of Europe’s current self-understanding as having outgrown its violent past.  相似文献
