We present radiocarbon dates and preliminary micromorphological information from the Neolithic cave site of Cueva del Toro (Antequera, Málaga, Spain). This site has yielded a rich early and late Neolithic archaeological record. The late Neolithic assemblage reflects specialized handcraft activity including in situ ceramic manufacture, textile production, and food processing along with sheep and goat penning, suggesting that the cave occupants and their domestic animals shared the same living space. Until now, dating of the stratigraphic sequence was incomplete, and the function of the combustion activities carried out at the cave remained unclear. New absolute dates from the main late Neolithic domestic activity area, corresponding to the most intense Neolithic occupation of the cave, allow us to place the entire sequence between 5320 and 5170 BP (or 4250–3950 to 2σ Cal BC). Micromorphological results show that many combustion features from this site represent recurrently burnt episodes on sheep/goat stabling deposits all along the sequence, corroborating human-goat/sheep cohabitation. This practice had not been previously documented in southern Spain for such early dates. Our results exemplify the importance of characterizing archaeological deposits at a microstratigraphic scale of observation.  相似文献

This paper demonstrates the results of analyses of Cladocera, pollen, plant macrofossil, lithological and radiocarbon data recovered from a mire located in the Rawka River valley in central Poland. These studies permit to recognise the development of hydrology phases in Kopanicha mire and give insight into Holocene fluvial dynamics of the system; radiocarbon dating partly allowed da-ting of the patterns of Holocene valley floor development of the Rawka River. The Kopanicha mire was formed during the Atlantic period. At that time, an oxbow lake formed, becoming a mire during the Subboreal and possibly Subatlantic periods. The high sensitivity of the oxbow lakes, fens, fauna, and flora remains to climate variations - especially to changes in water level connected with the ag-gradation-erosion cycle of rivers - allows the reconstruction of the palaeoecological changes that oc-curred in the mire. The frequency and timing of hydroclimatic oscillations at Kopanicha show strong similarities to records from other sites in Poland. Changes in Cladocera frequency and plant assem-blages were mostly influenced by the Rawka River which controlled the hydrological regime of the mire. The main factors controlling the presence of Cladocera taxa were the water level and the pres-ence of favourable conditions in the mire (e.g. pH, vegetation). Most of the changes occurred in re-sponse to climate changes, but some of them were connected with local factors.  相似文献

Different ideas are proposed all the time in archaeology. These often rise or fall based on how well they predict objective, measureable characteristics of the archaeological record. But other ideas are more paradigmatic, concerned with how we think about the archaeological record rather than the record itself. What determines which ideas rise or fall? This essay considers the specific question of why Lewis Binford’s middle-range approach became more prevalent over the very similar formation-process approach of Michael Schiffer in the 1970s and 1980s. It is hypothesized that while an approach’s ability to predict objective characteristics of the archaeological record is one selective factor, in this particular case, other factors, including personality and, especially, the association between Binford’s approach and significant, long-standing problems of prehistory, were also significant selective factors.  相似文献

The shuteibo, a type of communal cemetery characterized by a circular embankment, was constructed in the latter half of the Late Jomon (c. 1520 cal BC–1250 cal BC) in Hokkaido, Japan. Shuteibo at the Kiusu, Misawa-1, Bibi-4 and Kashiwagi-B sites are key to understanding the complex hunter-gatherer societies of the Late Jomon. Elite graves inside the shuteibo and non-elite graves outside them show clear differences in terms of grave goods, red ocher and grave markers at Kiusu-4. These communal cemeteries may have been created and maintained by elites who had access to highly valued materials, such as jadeite, through long-distance trade. Differences in the number of graves and grave goods among shuteibo at the Misawa-1 and Bibi-4 sites indicate differences in group size and intra-site elite differentiation. The Kiusu site has both the largest example and the largest concentration of these cemeteries in Hokkaido. At the inter-site level, differences in the size of these communal cemeteries indicate variability in the number of corporate groups as well as in relative power between sites.  相似文献

This section of the journal comprises two core sets of reports linked to work in 2017: finds and analyses relating to the Portable Antiquities Scheme (PAS) and site-specific discoveries and reports in medieval Britain and Ireland (MB&I), with a selection of highlighted projects. For the PAS report, reviews on coin and non-coin finds and on specific research angles are presented. For MB&I, the Society is most grateful to all contributors (of field units, museums, universities, developers, specialist groups and individuals) who have provided reports on finds, excavations, field-surveys and building analyses for 2017. For MB&I, see below for the format and content of the Fieldwork Highlights section and for contact details of the compilers. Annual Specialist Groups Reports appear in the Society’s Newsletter.  相似文献

This paper addresses the emotional dimensions of academic mentorship from a student mentee perspective and contributes to an emerging literature on geographies of emotion in higher education. It presents a pedagogical practice of self-reflexive co-mentorship – self-peer-ceptive feminist mentoring – and deploys it methodologically to analyze three biographical narratives. From different student mentee vantage points, these narratives reveal how the scales of the body, the family, and the nation are interwoven within the geopolitical and manifest within mentoring relationships. We argue that self-peer-ceptive feminist mentorship allows people at different academic career stages to share personal experiences of navigating the academy as a means to challenge institutional systems of power. Our argument answers three questions: How and why do we express and manage our emotions in mentoring relationships? What spatial scales are invoked through our emotional experiences and with what implications? How are different power structures embedded in the requirements, practices, successes, and failures of emotional management? Our discussion highlights how emotional masking and spill-outs are tools to navigate the emotional terrain of the neoliberalized academy. We conclude that self-peer-ceptive feminist mentoring can unsettle the structural hierarchies that require a “masking” of feelings for the sake of professional distance.  相似文献

A range of experiments were conducted in an attempt to create tar from the bark of Betula pubescens (downy birch) using an aceramic dry distillation process. Fire structures based on small pits and small kiln-like mounds were explored with a focus on fire intensities and differing burn times under field-based conditions. Heat penetration presented itself as an all-important factor, and the depth of the construction of the structures and features was considered to directly correlate to the impact of the heat. Single variable experiments confirmed that the necessary reducing atmosphere was achievable despite friable soil, but that heat would not penetrate a 50- to 80-mm-deep layer of grass turf. The evolution of structures from pits towards a raised type resulted in kiln-like structures which proved more successful. Though the experiments did not successfully produce tar as a finished product, they did lead to a better understanding of the dry distillation process of the established technology of birch bark tar extraction in aceramic societies.  相似文献

Unter dem Motto GrenzWerte wird der 55. Deutsche Geographentag vom 1. bis 8. Oktober 2005 in Trier stattfinden. Inmitten der Großregion SaarLorLux/Rheinland-Pfalz/Wallonien, die selbst von Grenzen unterschiedlichster Art durchzogen und umgeben ist, werden die Öffnung Europas nach Osten und weitere interessante Grenzaspekte Deutschlands thematisiert. Vielerorts wird diskutiert über Grenzen, die erreicht sind, beispielsweise im Verkehrswesen, beim Umweltschutz oder in Nachhaltigkeitsfragen. Das Motto GrenzWerte hat diesen Trend aufgegriffen und ließ neben der räumlichen auch eine inhaltliche Grenzdimension entstehen. Darüber, welche Anknüpfungspunkte sich daraus für die Angewandte Geographie ergeben, sprach der stellvertretende Vorsitzende des DVAG, DIPL.-GEOGR. KAI PARTALE , mit dem Vorsitzenden des Ortsausschusses für den Geographentag in Trier und Professor für Angewandte Geographie und Raumentwicklung an der Universität Trier, PROF. DR. HEINER MONHEIM.  相似文献

Denn eins ist sicher: Die Rente. Der vielzitierte Satz des früheren Arbeits- und Sozialministers Norbert Blüm klingt heute vielen wie Hohn. Der Altersaufbau der deutschen Bevölkerung erinnert grafisch immer mehr an einen Baum auf dünnem Stämmchen als an eine Pyramide. Angesichts dessen rücken demographische Entwicklungen mehr und mehr in den Fokus der Öffentlichkeit. Besonders die neuen Bundesländer sind massiv von Abwanderung und einem nie dagewesenen Geburtenrückgang betroffen. DIPL.-GEOGR. UTE C. BAUER sprach mit FRIEDRICH BLUTH und WOLF BEYER über die Besonderheiten der demographischen Prozesse in Berlin und Brandenburg. Beyer leitete bis Anfang 2004 das brandenburgische Referat für Raumbeobachtung. Seine Aufgabe bestand darin, Planungsgrundlagen für die Gemeinsame Landesplanung Berlin-Brandenburg(GL) zu schaffen. Dazu zählen auch Bevölkerungsprognosen für die Kreise und Städte Brandenburgs. Bluth ist in der Senatsverwaltung für Stadtentwicklung Berlin beschäftigt und leitet dort die Gruppe Stadtwissen, Stadtentwicklungsmonitoring, Bevölkerungsprognose.  相似文献
