Ottawa's Confederation Square was initially planned to be a civic plaza to balance the nearby federal presence of Parliament Hill. A century of federal planning, with the direct involvement of Prime Minister W.L. Mackenzie King, repositioned it as a national space in the City Beautiful style. Recent renovations have improved its pedestrian amenity and restored much of the original plan by French urban designer Jacques Gréber. The square contains the National War Memorial and the National Arts Centre, yet is a weak public space due to weak edge definition, animation, and spatial enclosure. The war memorial design was selected in a 1925 international competition won by Britain's Vernon March. The Great War monument was not installed until the 1939 Royal visit, and Mackenzie King intended that the re-planning of the capital would be the World War II memorial. However, the symbolic meaning of the Great War monument gradually expanded to become the place of remembrance for all Canadian war sacrifices. The National War Memorial is more successful as a symbolic object than Confederation Square is as a public space, yet both have evolved into important elements of the Canadian capital's national identity. 相似文献

The palaeobiota from a middle to late Holocene succession in Tom Thumbs Lagoon, N.S.W., Australia, reflects a range of environmental conditions caused by sea-level changes and active estuarine sedimentation. At the base of the succession (~ ?0.4 m AHD) a thin bed, containing molluscs dated at 6.7 ka B.P. by radiocarbon and amino acid racemisation, and foraminifers is indicative of open estuarine conditions. From +0.35 m AHD towards the top of the sequence the charophyte Lamprothamnium succinctum occurs in subrecent deposits. This species is characterised here by statistical measurements, and new characters are described and illustrated. The charophytes record a drop in sea level and the establishment of a lower salinity artificial wetland. The investigation has also established that decalcification in charophytes can be related to acidification produced by the release of organic acids, aggravated after 1928 by anthropogenic pollution. 相似文献
