The present study focuses on investigations carried out in the Late Vistulian succession of the Warta River deposits (central
Poland) in which a horizon of subfossil trees was excavated. Prelim-inary conclusions on time record and past environmental
conditions of a forest existence determined from radiocarbon dating, pollen analyses and geological evidence appear promising
with view of tree-ring chronologies. 相似文献
The cliff in Ustka is an active one. The area is one of the most eroded sea shores of the Polish coast. The Ustka Cliff mainly consists of Holocene sandy deposits, but its basis is built of glacial till and clay. Field search allowed to recognize the structure and sedimentary conditions of Holocene deposits exposed in the cliff. A comparison of dating results obtained for fossil soils and peat as well as aeolian deposits, using 14C and TL methods, respectively, with available literature records is presented. The evaluation of results obtained allowed to define three main dune-forming phases for the first time for this part of the Polish coast. During the research studies new data on the processes and environmental conditions was gained and the development of structure of the area during the last 10 thousand years was reconstructed. The analysis of available data from other sections of the southern Baltic coast shows that results obtained are age similar to those determined for the ?eba Spit. The research is part of a project concerning the geomorphology of the Ustka Bay. 相似文献
Diverse hunter-gatherer groups inhabited Tierra del Fuego (Argentina) from the end of the last glaciation until recent dates. Sadly, the contact with European settlers was fatal for them, and a series of different causes led to their disappearance. Among these groups, Selknam inhabited the central and northern part of the Isla Grande (Tierra del Fuego) until the first decades of twentieth century. Although many travellers and ethnographers described this society, the recorded information related to vegetal resources management and plant exploitation strategies was quite scarce. As a consequence, a picture was created in which plants, and especially plant food, had a very poor role in the everyday life of these people. In this work, we present the results of the first archaeobotanical analyses carried out on an excavated site related to the Selknam hunter-gatherers. The information presented here, along with future studies, will enlarge the knowledge and enrich the image that we have of Selknam’s plant use, economy and social relations. 相似文献
Cai, C.-Y., ?lipiński, A. & Huang, D.-Y., 31.3.2015. The oldest root-eating beetle from the Middle Jurassic of China (Coleoptera, Monotomidae). Alcheringa 39,488–493. ISSN 0311-5518.Jurorhizophagus alienus gen. et sp. nov., a new fossil root-eating beetle, is described and figured based on an exceptionally well-preserved impression fossil from the Middle Jurassic Daohugou beds (ca 165 Ma), Inner Mongolia, northeastern China. It represents the earliest fossil Monotomidae known to date. Jurorhizophagus can not be assigned to either of two subfamilies Monotominae or Rhizophaginae based on the unique combination of many unusual characters, including an 11-segmented antenna with a 3-segmented club, the presence of a distinct frontoclypeal suture and transverse pronotum with a median longitudinal groove. The discovery of a new genus from the Middle Jurassic highlights the antiquity of Monotomidae and provides new information about the phylogenetic relationships between Monotomidae and its allied families.Chen-Yang Cai [caichenyang1988@163.com], Di-Ying Huang [dyhuang@nigpas.ac.cn] (corresponding author), State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, PR China; Adam ?lipiński [adam.slipinski@csiro.au], Australian National Insect Collection, CSIRO National Collections Australia, GPO Box 1700, Canberra ACT 2601, Australia.相似文献
The newly collected “Potsdam Grievance Statistics File” (PGSF) holds data on the number and topics of grievances (“Eingaben”) that were addressed to local authorities of the German Democratic Republic (GDR) in the years 1970 to 1989. The PGSF allows quantitative analyses on topics such as participation, quality of life, and value change in the German Democratic Republic. This paper introduces the concepts of the data set and discusses the validity of its contents. 相似文献
This paper is a preliminary look at the recent emergence of the family as a major theme of Australian electoral politics. It shows that while both the Liberal and Labor Parties are attempting to make political capital out of the family, there are significant differences in their approach. While the Labor Party has been more inclined to accept diversity in the form of the family and the need to support primary carers, the Coalition has given priority to ‘strengthening the traditional family’ and its role as an alternative to welfare state provision. The paper deconstructs campaign material from recent federal and State elections in terms of message and intended audience. It notes the dangers of political discourse based on manipulation of highly charged symbols such as the family, the flag and the nation.
The second half of the paper analyses some of the implications of using the family as a focus for social policy. It examines the contradictions between social policy based on the treatment of the family as an undifferentiated unit and policy which recognises the importance of interfamily and intrafamily inequalities. It looks at issues raised by family policy as a focus for redistribution and provision of services on the one hand, and as a means of reducing public expenditure and reinforcing dependence on male family heads on the other. The stress on the importance of the family is rarely accompanied by a comparable dedication to assessing the role of unpaid caring work in the economy or to achieving equal opportunity for workers with family responsibilities. 相似文献
Our knowledge of the migration routes of the first anatomically modern populations colonising the European territory at the beginning of the Upper Palaeolithic, of their degree of biological, linguistic, and cultural diversity, and of the nature of their contacts with local Neanderthals, is still vague. Ethnographic studies indicate that of the different components of the material culture that survive in the archaeological record, personal ornaments are among those that best reflect the ethno-linguistic diversity of human groups. The ethnic dimension of beadwork is conveyed through the use of distinct bead types as well as by particular combinations and arrangements on the body of bead types shared with one or more neighbouring groups. One would expect these variants to leave detectable traces in the archaeological record. To explore the potential of this approach, we recorded the occurrence of 157 bead types at 98 European Aurignacian sites. Seriation, correspondence, and GIS analyses of this database identify a definite cline sweeping counter-clockwise from the Northern Plains to the Eastern Alps via Western and Southern Europe through fourteen geographically cohesive sets of sites. The sets most distant from each other include Aurignacian sites from the Rhône valley, Italy, Greece and Austria on the one hand, and sites from Northern Europe, on the other. These two macro-sets do not share any bead types. Both are characterised by particular bead types and share personal ornaments with the intermediate macro-set, composed of sites from Western France, Spain, and Southern France. We argue that this pattern, which is not explained by chronological differences between sites or by differences in raw material availability, reflects the ethnolinguistic diversity of the earliest Upper Palaeolithic populations of Europe. 相似文献
