Historical space as narrative medium: on the configuration of spatial narratives of time at historical sites 总被引：1，自引：0，他引：1
This paper examines how narratives of history are organized spatially at historical sites and memorial spaces, especially
in urban settings and in places invested with a sense of collective memory. Much recent research has focused on landscape,
memory, and place and how relationships of political and social power influence the representation of historical events in
public spaces. Although the meaning of such sites may be hotly contested for long periods of time, we focus here on narrative
theory and the related, but unexplored, issue of how such historical stories are configured on the ground at actual historical
sites. We identify a number of narrative strategies which are frequently used to configure historical stories in space. Declamatory
strategies using markers presenting a snapshot of an event are common, but sequential and non-sequential linear strategies
are also used, as are thematic strategies that cross-cut space and time to present complex historical stories at various spatial
scales. Examples are drawn from a range of historical sites in North America, Europe and Israel. 相似文献

This paper investigates the conflict that arose as the result of opening a McDonald's restaurant adjacent to a national shrine in Israel. This conflict transformed Golani Junction, previously associated with the meanings assigned to the Golani memorial, into a contested place and a controversial issue. The paper outlines the conflict and the attempts to reach a compromise solution. The main argument is that the conflict reflects the notion prevalent among those dedicated to the memorial site and to the values it enshrines that the restaurant defies the sacred character of the place and marginalized the memorial in the local landscape. The conflict of meaning is also associated with McDonald's being construed as a prominent symbol of the alleged Americanization of Israeli society and culture. With this, the controversial character of the Golani Junction is also an aspect of a wider debate concerning cultural identity in Israel. Beyond the local context and specific issues involved, the controversies that transform the Golani Junction into a contested place demonstrate how conflicting interpretations of place and the politics of its meaning are formulated in terms of landscape features and architectural details. 相似文献

Uptake of anthropogenic CO2 by the oceans is altering seawater chemistry with potentially serious consequences for coral reef ecosystems due to the reduction of seawater pH and aragonite saturation state (Ωarag). The objectives of this long-term study were to investigate the viability of two ecologically important reef-building coral species, massive Porites sp. and Stylophora pistillata, exposed to high pCO2 (or low pH) conditions and to observe possible changes in physiologically related parameters as well as skeletal isotopic composition. Fragments of Porites sp. and S. pistillata were kept for 6-14 months under controlled aquarium conditions characterized by normal and elevated pCO2 conditions, corresponding to pHT values of 8.09, 7.49, and 7.19, respectively. In contrast with shorter, and therefore more transient experiments, the long experimental timescale achieved in this study ensures complete equilibration and steady state with the experimental environment and guarantees that the data provide insights into viable and stably growing corals. During the experiments, all coral fragments survived and added new skeleton, even at seawater Ωarag < 1, implying that the coral skeleton is formed by mechanisms under strong biological control. Measurements of boron (B), carbon (C), and oxygen (O) isotopic composition of skeleton, C isotopic composition of coral tissue and symbiont zooxanthellae, along with physiological data (such as skeletal growth, tissue biomass, zooxanthellae cell density, and chlorophyll concentration) allow for a direct comparison with corals living under normal conditions and sampled simultaneously. Skeletal growth and zooxanthellae density were found to decrease, whereas coral tissue biomass (measured as protein concentration) and zooxanthellae chlorophyll concentrations increased under high pCO2 (low pH) conditions. Both species showed similar trends of δ11B depletion and δ18O enrichment under reduced pH, whereas the δ13C results imply species-specific metabolic response to high pCO2 conditions. The skeletal δ11B values plot above seawater δ11B vs. pH borate fractionation curves calculated using either the theoretically derived αB value of 1.0194 (Kakihana et al. (1977) Bull. Chem. Soc. Jpn.50, 158) or the empirical αB value of 1.0272 (Klochko et al. (2006) EPSL248, 261). However, the effective αB must be greater than 1.0200 in order to yield calculated coral skeletal δ11B values for pH conditions where Ωarag ? 1. The δ11B vs. pH offset from the seawater δ11B vs. pH fractionation curves suggests a change in the ratio of skeletal material laid down during dark and light calcification and/or an internal pH regulation, presumably controlled by ion-transport enzymes. Finally, seawater pH significantly influences skeletal δ13C and δ18O. This must be taken into consideration when reconstructing paleo-environmental conditions from coral skeletons. 相似文献
