The Gombore II site dates to circa the Brunhes Matuyama Reversal and is one of the Acheulean localities of the Melka Kunture
(Upper Awash, Ethiopia) archaeological complex, known since the 1970s. In 2001, this locality was selected as the site for
an Open Air Museum and thus excavated. The excavation area has yielded an abundant Acheulean lithic assemblage manufactured
on volcanic raw materials in close association with numerous paleontological remains. A technological analysis was carried
out on a fraction of the bifacial tools (bifaces and cleavers) which could be temporarily removed from the displayed surface
in the museum. This set of artefacts reveals new data about the bifacial shaping strategies adopted at the beginning of the
Middle Pleistocene in Ethiopia. The use of obsidian and the systematic manufacturing of twisted bifaces are original features
of the assemblage. These data are discussed in the framework of penecontemporaneous East African sites. 相似文献

W edge -shaped soil structures occur in many parts of southern Canada and the northern United States. These have usually been interpreted as being ice-wedge casts. Yehle (1954), however, has expressed concern over the confusion of fossil ice wedges with features he termed soil tongues, but also referred to as soil pendants (Wright 1961) or podsolschornsteine (Johnsonn 1959). Not only are soil tongues superficially similar to ice-wedge casts, but they also occur in temperate latitudes which may have experienced periglacial conditions during the Pleistocene. Soil tongues, however, are solutional features, formed by rainwater percolating through unconsolidated calcareous deposits. They may be distinguished from ice-wedge casts and other wedge-shaped structures by: (a) the presence of pebble or other marker beds extending unbroken across the wedges; (b) the absence of bed contortions or pressure features in the materials adjacent to the wedges; (c) their conical three-dimensional shape; and (d) the lower carbonate content in the sediments of the wedges than in the surrounding materials. 相似文献

After having experienced a period of steady economic and demographic growth in the 1960s, the Canton of Neuchatel was very severely hit by the crisis of 1975 and subsequently by that of 1982. Industrial activity suffered the consequences of these two successive recessions, in particular in horology. To fend off the crisis, the political authorities of the canton decided to pursue an active policy of business promotion. In parallel with these efforts, the territorial production system underwent considerable transformation. However, new forms of territorial development must now be considered in order to ensure that it can adapt to the continuous changes in the business environment. This paper is divided into four parts. First, it is important to set out the economic context in which the canton of Neuchatel has evolved in recent decades. Second, we have considered the various business promotion measures undertaken by the canton and the Confederation. This leads us to the third part, which describes the transformation of the territorial production system. As for the fourth and last part, it describes the new strategic directions that the canton of Neuchatel can pursue in the field of economic development. 相似文献

The 1950s and 1960s constitute a key “moment” in the history of the looting of archaeological sites in Southeast Asia. The emergence in the region at that time of a commodity market for antiquities such as pottery triggered a wave of illicit excavation of archaeological sites. Simultaneous with the trafficking of antiquities out of the Philippines and Thailand into the hands of private collectors and museums in the West during this period and subsequent decades a thriving domestic antiquities market developed. It is argued here that the valorization of antiquities as national heritage, rather than inhibiting acquisition by citizen collectors, facilitated a process wherein collecting became a form of cultural capital accumulation. It is inaccurate to categorize Thailand and the Philippines simply as “source” or “supply” nodes in the global antiquities trade. This paper aims for a more nuanced approach to the geoeconomics of antiquities consumption. 相似文献

Contact with nature is vital for the development of children and teenagers. In the past, informal urban green spaces (IGS) such as vacant lots appear to have been used for such purposes. We need to better understand how previous generations used IGS to make sure young people today can also enjoy its social, mental, emotional and physical health benefits. This study quantitatively compared adult residents' memories of IGS use in their childhood and teenage years in two geographically and culturally distinct cities: Brisbane, Australia, and Sapporo, Japan. The results showed most respondents (>70%) remembered using IGS in the past, and preferred it over other green space because it was easily accessible. Most (>70%) recalled experiencing no problems (e.g. danger of injury) when using IGS, a contrast to recently increasing parental concern for children's safety. Such factors may limit present IGS use and prevent it from fulfilling the important role it played for previous generations' recreation. 相似文献

Apart from Lucian's Demonax, our only other sources on Demonax the philosopher are the Greek gnomologia. These were exploited by K. Funk in his major study of 1907, but Funk was ill informed about the nature of the gnomological sources. The present article gives a concise overview of modern scholarship regarding Lucian's Demonax and the debate on Demonax's historical existence. It then presents the gnomological sources and provides a new and improved edition of the Greek gnomological material along with an English translation. 相似文献
