The narratives encompassed by both productions revolve around shared Australian histories, for audiences attracted by place and what it is able to represent. Re-enactments of past events call into the present a consideration of what still remains, with both shows enabling new subjective interpretations of earlier times. The defining difference between the two, however, rests in the context of each performance, in the one case as a commodification of heritage and in the other case as the desire to produce an artistic yet popular theatrical product. Ballarat＇s, Sovereign Hill＇s light and sound show, Blood on the Southern Cross celebrates and commemorates, in mega-spectacle style, the Eureka Stockade, one of Australia＇s key historical events. Using a mechanised display of the original goldmining site of the Eureka rebellion, the performance is operated by computers with video-projection, multi-phonic sound, and moving model forms, with audiences moved around the massive site on transporters. The Piccolo Tales, a contrasting performance most notably in terms of size, unfolds the history of Kings Cross, through its setting in the miniscule iconic Piccolo Bar, in one of the tiny side streets of Sydney＇s bustling and densest suburb. This paper encompasses an investigation of how the cultural inscriptions of the two specific sites interweave with the performance styles, materials, political and social positioning of the works. Previous performance studies examining site-specificity are utilised, including the author＇s analysis of particular festival performances as ＂place-making＂ （Hayes, 2012, 2013）. Smith＇s （2009） model of ＂signposts＂ is used to consider acting within site-specific productions in a new light, whilst both performances are more completely analysed through Schneider＇s （2011） concept of incomplete pasts forming ＂cycles of memory＂.展开更多

The importance of preserving the architectural heritage is more meaningful when the building is preserved with its whole environment, with the other historical buildings around as a site protection. Preservation of historical monuments not only individually but also with their environments help the city regain its identity that it has lost. The Conservation Approach to Cultural Assets in Turkey has reached to its peek starting from 1985＇s through introducing the effects of the recent amendment on cultural heritage law and the impact of the EU integration process. The municipalities started to use this recent amendment on cultural heritage laws as a method of recovering their cities for the local identity searches. This paper will deal with the current challenges for conservation practice in Turkey, through introducing the effects of the recent amendment on cultural heritage law and the impact of the EU integration process, and examine some major promising conservation and renovation, rehabilitation projects continuing in Izmir the third biggest city of Turkey for which local solutions are being devised for problems of global context in the meaning of local identity searches for the city.展开更多

The re- sults show that clay minerals at Site U1340 are dominated by illite, with a moderate amount of smectite and chlorite, and minor kaolinite. Sediment source studies suggest that the clay mineral assemblages and their sources in the studied core are controlled primarily by the climate conditions. During the warm periods, clay minerals originated mainly from the adjacent Aleutian Is- lands, and smectite/（illite＋chlorite） ratios increased. During the cold periods, clay minerals from the Alaskan region distinctly increased, and smectite/（illite＋chlorite） ratios declined. Based on smectite/（illite＋chlorite） ratios and clay mineral crystallinities the evolutionary history of the paleoclimate was revealed in the Bering Sea. In general, the Bering Sea was characterized by warm and wet climate condition from 4.3 to 3.94 Ma, and then cold and dry condition associated with the enhanced volcanism from 3.94 to 3.6 Ma. Thereafter, the climate gradually became cold and wet, and then was dominated by a cold and dry condi- tion since 2.74 Ma, probably induced by the intensification of the Northern Hemisphere Glaciation. The interval from 1.95 to 1.07 Ma was a transitional period of the climate gradually becoming cold and wet. After the middle Pleistocene transition （1.07 to 0.8 Ma）, the Bering Sea was governed mainly by cold and wet climate with several intervals of warm climate at -0.42 Ma （MIS 11）, -0.33 Ma （MIS 9） and ~0.12 Ma （MIS 5）, respectively. During the last 9.21 ka （the Holocene）, the Bering Sea was characterized primarily by relatively warm and wet climatic conditions.展开更多
