The reflection of human activity in the sediments of Iwankowskie Lake from Subatlantic Phase (Polish Outer Carpathians) 总被引:2,自引:0,他引:2
Anna Bucała Włodzimierz Margielewski Leszek Starkel Krzysztof Buczek Valentina Zernitskaya 《Geochronometria》2014,41(4):377-391
The paper presents the analysis of organic and mineral sediments filling the depression, which developed over the landslide located at the slope (767–773 m a.s.l.) of Lubań ridge decscending to the Ochotnica river valley in the Polish Flysch Carpathians. The landslide formed in an early stage of the Subatlantic Phase (2490 ± 35 BP). The top of peat is dated at 1360 ± 50 years BP and is covered by 72 cm of clayey silts with some sandy intercalations, which indicate slopewash after deforestation. The pollen of ruderal plants and Cerealia (undiff.) reflect agricultural activity in the surroundings. The fragments of charcoal indicate the age of the forest clearance to the first half of the 17th century. The late forest clearance at the elevated north exposed slopes followed 200–300 years later in relation to the foundation of the village at the valley floor. 相似文献

Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya 总被引:2,自引:1,他引:1
This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both. 相似文献

ABSTRACT This article deals with how, in the urban setting of Madang, Papua New Guinea, Marian devotion is deployed in response to domestic and gender‐based violence. While providing insight into the lived religious experiences of Catholic women living in Madang, this article shows how Mary empowers her followers to resist violence, yet, at the same time, paradoxically, is instrumental in sanctioning women to tolerate violence. Josephine's ‘journey of violence’ reveals not only Josephine's turning to Mary, but more so, her negotiations with values belonging to different cultural logics. Caught between ‘tradition’, Christianity and ‘modernity’, Josephine and other Catholic women engage in painful processes of self‐analysis and self‐transformation to adapt to and change their situation. In these processes, Mary is used as a role model. 相似文献

Studies of old aerial photographs of the Bahrain burial mound fields have revealed that a small number of both Early Type (c. 2200–2050 BC) and Late Type (c. 2050–1750 BC) mounds are encircled by an outer ring wall, apparently marking out the mound as belonging to an elite. Four of these mounds have been excavated, and the results are presented. The geological differences between the Early Type and the Late Type mound landscapes are discussed. 相似文献
