Archaeological and historical investigation of WWII battles fought in the Micronesian archipelago of the Mariana Islands has generally concentrated on the fierce struggles for Saipan, Tinian, and Guam. Smaller islands that were neutralised during the U.S. thrust to establish air bases for the bombing campaign over Japan beginning in 1944 have received less attention, but were a strategic link in the Absolute National Defence Sphere. This paper examines the archaeological evidence of Japanese military planning for the defence of the island of Pagan situated north of Saipan, a battle that was never fought. The strategy based on an analysis of fixed weaponry emplacement appears to have been conceived in terms of engagement evolving from a ‘defence-at-the-waters-edge’ tactic in the southern Mariana Islands towards a ‘defence-in-depth’ posture faced in Iwo Jima and Okinawa.  相似文献

Analysis of starch granules, phytoliths, and plant macrofossils from archaeological features and carbonized food residue provides important new insight into the extent of prehistoric maize (Zea mays) consumption on the North American Great Plains. These data suggest that consumption of maize, and probably other cultigens, was widespread on the eastern Canadian Prairies between approximately AD 1000 and 1600. Domesticated plants may have been grown locally, acquired through trade, or transported into the region following dispersal of family groups from horticultural villages located elsewhere. However, the lack of strong artifactual evidence of gardening, and the small-scale nature of sites on the eastern Canadian Prairies indicate that local horticulture, if practiced, was non-intensive.  相似文献

The aim of this article is to explore the complexity of the online sex trade and work by analysing sexuality-related commercial websites, with reference to three European states, France, Greece and Slovenia. The article compares websites in each specific sociocultural context, in order to provide insights into the various types of networks and services that emerge, and to explore how they operate, how they communicate and how sex is being merchandised. We have conducted a two-tier analysis: The first part discusses results of a quantitative macro-analysis exploring 149 websites, while the second part is a micro-analysis analysing the visualisation of egocentric network of three selected websites. The focus is on understanding how gender relations develop in digital environment and how within cyberspace sectorial and national divides are dealt with. While there is evidence to suggest that in some sectors the Internet has opened avenues for sex workers to work independently of the control networks, there are also many forms of exploitation that arise from new media. We observe that sex commerce online is not particularly attentive to the agency of sex workers but is, to the contrary, oriented to provide opportunities and a forum for businessmen and clients.  相似文献

The plain of Thessaloniki is an important area from a historical standpoint. Numerous reigns and empires have occupied the area, leaving behind numerous archaeological remains. The literature and historical evidences show that the city of Pella was located near the sea and its harbor was the starting point of various conquests of famous kings such as Philip the 2nd and Alexander the Great. At present, the ancient capital is located 28 km inland the large fertile plain of Thessaloniki.  相似文献
