We determined the 230Th/U ages of individual calcite layers that grew on the walls of artificial water‐supply tunnels (‘water quarries’) at Troy/Ilios by using thermal ionization mass spectrometry. The oldest age of overgrowth being 4350 ± 570 years, the tunnels must have been built a short time earlier, during the archaeological period Troy I–II. The tunnels were also used during Troy VI–VII (1700–1150 bce, a period that includes the date of the supposed ‘Trojan War’), in Homeric times (c. 720 bce) and in the Roman period. These findings add strong support to the identification of the water quarries with a natural phenomenon and Anatolian deity known in Hittite texts of the second millennium bce as KASKAL.KUR, a term denoting subsurface water systems. Consequently, they reinforce the view that Troy in the second millennium bce was Anatolian in character. In this way, the findings are also consistent with the identification of (W)Ilios with Wilusa, a city attested to in Hittite historical texts.  相似文献

The Laibin hominid represents one of the rare finds of modern Homo sapiens in China, rare for its relative completeness and well-established stratigaphic provenance. This paper presents the results of mass spectrometric U-series dating of intercalated calcite samples from the Laibin site. The capping flowstone and the calcite vein, which sandwich the hominid fossil-containing deposits, date to 38.5 ± 1.0 and 44.0 ± 0.8 ka, setting respectively the minimum and maximum ages to the fossils. The second flowstone layer is 112.0 ± 1.4 ka old, indicating that the cultural sequence may possibly extend to somewhere between 44 and 112 ka. Securely dated Laibin finds should be of importance in reconstructing human physical and cultural evolution in the region.  相似文献

A calcium carbonate (calcite) bladder calculus was found in the pelvis of an adult female buried in a Mesolithic cave‐tomb on the coast of Sicily; it was dated by 14 C to around 6500 bc . Its chemical composition, which was not known before, was determined by means of Fourier transform–infared microspectroscopy (FT–IR–M) using the high‐pressure diamond cell, a device that makes it possible to analyse a small amount of the sample (1–2 µg). In this way, the analysis of all the laminations of the calculus was performed without destroying the sample. Although calcite was the main component, carbonate apatite was also detected in the nucleus and in a more external layer.  相似文献

The infrared radiofluorescence (IR-RF) dating technique was applied to eight fluvial samples that were collected from two sediment cores at the Heidelberg Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the IR-RF derived ages of the samples it was possible to establish a chronological framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin. The results allow us to distinguish between four main periods of aggradation. The lowermost sample taken from 100 m core depth lead to an IR-RF age of 643 ± 28 ka pointing to a Cromerian period of aggradation (OIS 17–16). For the Elsterian it is now possible to distinguish between two aggradation periods, one occurring during the Lower Elsterian period (OIS 15) and a second during the Upper Elsterian period (OIS 12–11). For the so called Upper interlayer (or “Oberer Zwischenhorizont” — a layer of organic-rich and finer-grained deposits), the IR-RF results point to a deposition age of around 300 ka, with samples taken directly on top and out of this layer yielding IR-RF ages of 288 ± 19 ka and 302 ± 19 ka, respectively. Hence, the measured IR-RF ages clearly point to a deposition during the Lower Saalian period (OIS 9–8) whereas earlier studies assumed a Cromerian age for the sediments of the Upper Interlayer based on pollen records and also mollusc fauna. The new IR-RF dataset indicates that significant hiatuses are present within the fluvial sediment successions. In particular the Eemian and Upper Saalian deposits are missing in this part of the northern Upper Rhine Graben, as the 300 ka deposits are directly overlain by Weichselian fluvial sediments. It is obvious that time periods of increased fluvial aggradation were interrupted by time periods of almost no aggradation or erosion which should have been mainly triggered by phases of increased and decreased subsidence of the Heidelberg Basin.  相似文献

The age of Neanderthal remains and associated sediments from El Sidrón cave has been obtained through different dating methods (14CAMS, U/TH, OSL, ESR and AAR) and samples (charcoal debris, bone, tooth dentine, stalagmitic flowstone, carbonate‐rich sediments, sedimentary quartz grains, tooth enamel and land snail shells). Detrital Th contamination rendered Th/U dating analyses of flowstone unreliable. Recent 14C contamination produced spurious age‐values from charcoal samples as well as from inadequately pretreated tooth samples. Most consistent 14C dates are grouped into two series: one between 35 and 40 ka and the other between 48 and 49 ka. Most ESR and AAR samples yielded concordant ages, ranging between 39 and 45 ka; OSL dating results permitted adequate bracketing of the sedimentary layer that contained the human remains. Our results emphasize the value of multi‐dating approaches for the establishment of reliable chronologies of human remains.  相似文献

In the 25 years since Marilyn Strathern published The Gender of the Gift (1988) its signature concepts of the ‘dividual androgyne’ and ‘sociality’ have received almost no criticism in the anthropological literature and are now widely accepted as true. The ‘dividual’ is considered to be ‘a new, non‐unitary model of embodiment and … one of the most important theoretical accomplishments to emerge from Melanesian ethnography in the latter part of the 20th Century’ despite the fact that it erases affect, agency, identity and other essential features of human beings (Lipset 2008). The present critique of Strathern's concept of the androgynous ‘dividual’ challenges its legitimacy as a Melanesian or any other ‘premodern’ form of personhood and suggests that it expresses the wish of academic feminists in the 1970s and 1980s to locate an indigenous model for androgyny and to characterise patriarchy, misogyny and sexual segregation as peculiarly Western. The article explores aspects of Gimi myth, ritual and exchange which Strathern claims helped her to formulate the concept of the ‘dividual’ (especially those surrounding men's sacred bamboo flutes) and concludes that she mistook a virulently anti‐female ideology – including a fantasy in which men may subsume or incorporate certain aspects of female anatomy – for benign accommodation between the sexes. The ‘dividual’ does not correspond to social reality among the Gimi and paradoxically affirms Lévi‐Strauss' classic demonstration in the Elementary Structures of Kinship (1949) that ‘the gender of the gift’ is invariably female.  相似文献

Traditionally, the Balearic so‐called ‘quicklime burials’ of the Iron Age have been considered to be inhumations in quicklime. The general appearance of the bones, however, resembles more closely that of cremated bones. Laboratory tests reveal that the observed features of the bones from these burials, including cracks, thumbnail fractures and warping, cannot be explained by an inhumation in quicklime. The δ 13C value, Fourier transform infrared spectra, SF values and the low carbon content of the apatite moreover indicate a thermal manipulation of the bones. The 14C content is depleted with regard to the accepted archaeological age of the sample, which can best be explained by carbon exchange between bio‐apatite and fossil CO2 released during the heating of limestone. This implies that the Balearic ‘quicklime burials’ must be interpreted as an elaborate cremation practice in presence of limestone. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

A long‐term pump test was conducted in the KTB pilot borehole (KTB‐VB), located in the Oberpfalz area, Germany. It produced 22 300 m3 of formation fluid. Initially, fluid production rate was 29 l min?1 for 4 months, but was then raised to an average of 57 l min?1 for eight more months. The aim of this study was to examine the fluid parameters and hydraulic properties of fractured, crystalline crusts as part of the new KTB programme ‘Energy and Fluid Transport in Continental Fault Systems’. KTB‐VB has an open‐hole section from 3850 to 4000 m depth that is in hydraulic contact with a prominent continental fault system in the area, called SE2. Salinity and temperature of the fluid inside the borehole, and consequently hydrostatic pressure, changed significantly throughout the test. Influence of these quantities on variations in fluid density had to be taken into account for interpretation of the pump test. Modelling of the pressure response related to the pumping was achieved assuming the validity of linear Darcy flow and permeability to be independent of the flow rate. Following the principle ‘minimum in model dimension’, we first examined whether the pressure response can be explained by an equivalent model where rock properties around the borehole are axially symmetric. Calculations show that the observed pressure data in KTB‐VB can in fact be reproduced through such a configuration. For the period of high pumping rate (57 l min?1) and the following recovery phase, the resulting parameters are 2.4 × 10?13 m3 in hydraulic transmissivity and 3.7 × 10?9 m Pa?1 in storativity for radial distances up to 187 m, and 4.7 × 10?14 m3 and 6.0 × 10?9 m Pa?1, respectively, for radial distances between 187 and 1200 m. The former pair of values mainly reflect the hydraulic properties of the fault zone SE2. For a more realistic hydraulic study on a greater scale, program FEFLOW was used. Parameter values were obtained by matching the calculated induced pressure signal to fluid‐level variations observed in the KTB main hole (KTB‐HB) located at 200 m radial distance from KTB‐VB. KTB‐HB is uncased from 9031 to 9100 m and shows indications of leakage in the casing at depths 5200–5600 m. Analysis of the pressure record and hydraulic modelling suggest the existence of a weak hydraulic communication between the two boreholes, probably at depths around the leakage. Hydraulic modelling of a major slug‐test in KTB‐HB that was run during the pumping in KTB‐VB reveals the effective transmissivity of the connected formation to be 1 to 2 orders of magnitude lower than the one determined for the SE2 fault zone.  相似文献

In an earlier paper published in this journal Nancy Munn's ‘The Transformation of Subjects into Objects in Walbiri and Pitjantjatjara Myth’ was discussed and related to Aranda mythology. This paper commences where the earlier one finished and offers a psychological account of ‘the transformation of subjects into objects’. In particular, it discusses, within a psychoanalytic framework, the relationship between communication, the body and the environment inherent in Aranda myth and rite, suggesting that what Munn calls ‘the a priori grounds’ of the Aboriginal moral order can be understood as a set of dialectical shifts occurring within the life-cycle. These shifts involve the realisation and reconciliation of a number of oppositions, including male and female; earth and sky, death and life; conscious and unconscious; and, in particular, language and speech.  相似文献

During the 1991–1992 excavation of the ruins of the medieval cathedral in Hamar, Norway, the broken skull of an elderly man was found, showing evidence of an incomplete trepanation. The ‘surgeon’ had obviously tried to penetrate the skull surface around bregma in an irregular circle of 23 × 21 mm. Upon investigation, the skull revealed a reactive‐pathological area of the internal surface of the occipital bone, which probably represents a respite after a meningeal disorder (a tumour or an infectious process), causing us to suggest that the trepanation was meant to cure the patient's increasing headache. However, as a second skull with similar marks was found in the same churchyard, another explanation seems possible. Because the brain tumour in the first case may have altered the patient's mental state, we may surmise that these incomplete operations were an attempt to remove from these patients' heads the ‘Stone of Madness’, which was then commonly considered to be the reason for psychiatric diagnoses as well as persistent headache, and often depicted in European art, most notably in the 16th and 17th centuries. The second skull, revealing an even more incomplete attempt, did not show any skeletal pathology at all. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Sometimes we come across objects that truly intrigue us. Not necessarily because they are great examples of art, or because they are made of precious materials, but because there is some other quality which captures our attention. One of these can be age. Just as age adds character to people’s faces, the patina of an object or visible signs of damage and use instils an object with a certain ‘charisma’ or ‘aura’. This paper examines in detail the so‐called grotesque torc, a neck‐ring dating to the Iron Age which has been extensively repaired. The repairs are crude and obvious, which gives the object its distinctive appearance. It is argued that these signs of age, inscribed onto the artefact through its life, imbued the torc with a timeless ‘anachronic’ quality: its visible age manifests a certain charisma or aura, helping facilitate a plural relationship with time.  相似文献

Science and music. Introductory remarks. The article presents a brief introduction to “Science and Music”, theme of the 44th symposium of the “Society for History of Sciences” held in Munich in Mai 2007. The text begins with a brief reference to the numerous biographical connections between the two fields, but focuses primarily on topics that reveal music and the sciences to be results of shared cultural practices. Examples include: (1) shared objects in the material sense, meaning the use of particular instruments in both music and the sciences; (2) shared semantics, metaphors, and concepts, for example the use of the concepts like clang or tone color in acoustics and the psychology of audition, or talk of ‘mood’ and ‘harmony’ in both music and in literature; (3) direct interactions between mathematics, physics and music, for example in the electronic music of the twentieth century.  相似文献

This article argues that Horner and Hulme's call for moving towards ‘global development’ to do justice to changing 21st century development geographies neither contributes to advancing our understanding of contemporary development challenges nor helps articulate realistic responses to tackle them. A key problem is that they try to explain several general trends in the geography of development with reference to mainstream statistics without appropriate critical reflection or adequate theorization. Focusing specifically on the environmental and conservation aspects of development, this article contends that these omissions not only confuse the debate on the current state and geographies of development, they risk something more serious, namely the reinforcement of a generic development narrative which will intensify 21st century development challenges. The article concludes that what we need is not global development but revolutionary development.  相似文献

New radiometric data are reported from the recent excavation of the type locality of the Early Upper Palaeolithic entity of the Bohunician. Recently obtained radiocarbon (14C) data on charcoal are compared with new Optically Stimulated Luminescence (OSL) dating of sediment. OSL ages were determined on sediment from the archaeological occupation at Brno-Bohunice, as well as from the over- and underlying loessic sediments. Multiple techniques were applied, which all gave congruent results. While a dual protocol (post IR-OSL) failed the quality criteria tests, ages were obtained by Multiple-Aliquot-Additive-Dose (MAAD) on polymineral material and Single-Aliquot-Regeneration (SAR) on fine grain quartz extract as well as on polymineral material. Fading tests show significant loss of Infrared Stimulated Luminescence (IRSL) after storage for 3 and 12 months for one sample, but little or no fading for others. The resulting (uncorrected) age estimates are smaller than those on quartz by OSL methods. The latter are considered to be more reliable estimates of the sedimentation age of these deposits. The measured OSL doses do not show a simple distribution and the lowest 5% was used for age calculation to represent the most likely sedimentation age. The quartz from the loess overlying the archaeological layer is OSL dated to 30.9 ± 3.1 ka, while the sediment for the paleosol which contains the archaeological layer gave an age of 58.7 ± 5.8 ka. The attribution of this paleosol to the Hengelo interstadial is therefore questionable. However, if the Hengelo interstadial is correlated with the Dansgaard/Oeschger (D/O) event 12, statistical agreement within 2-σ is achieved. The OSL result for the archaeological layer is in accordance with a weighted average TL date on heated flint artifacts of 48.2 ± 1.9 ka from this layer as well as calibrated radiocarbon data (CalPal Hulu 2007) from nearby locations. However, radiocarbon data on charcoal samples obtained during excavation at Brno-Bohunice 2002 provide age estimates between 30 and 40 ka 14C-years, which translate to approximately (33) 35–44 ka on the calendric time scale according to the Hulu 2007 model. For the underlying loess a depositional age of 104.3 ± 10.6 ka was obtained by OSL. The presented OSL ages indicate that a simple correlation of soil sequences between sites within a region has to be verified by chronometric dating.  相似文献

ABSTRACT. The 1919 Versailles Peace Conference created new states in East Central Europe (ECE), but the imperfect implementation of the ‘one nation, one state’ formula resulted in more than twenty‐five million ‘unassimilable’ minorities. With the introduction of majoritarian democracy, this gave rise to what we term ‘ethnic reversals’: ‘formally dominant majorities’ suffered status decline, while previously ‘minoritised majorities’ found new political powers. Accordingly, the 1919 Minorities Treaties sought to manage these ‘ethnic reversals’ by instituting a liberal minority rights regime that tried to create both ‘tolerant majorities’ and ‘loyal minorities’. While the Treaties reflected the influences of Anglo‐American and Anglo‐American Jewish elites – the most notable voices of liberalism in an age of ethnic homogenisation – we suggest that in contexts of historical diversity with little institutionalised liberalism, ‘ethnic reversals’ raise issues that cannot be resolved within liberal conceptions of minority rights that rely solely or primarily on cultural protections.  相似文献

This article examines how and in which societal and political contexts nationhood is expressed and symbolised in reunified Germany. This ‘rediscovery’ of nationhood since the 1990s mixes new and old motifs of the cultural repertoire of ‘the national’ for different purposes. Three main contexts triggered a rediscovery of ‘the national’ after 1989: reunification, immigration and the retrenchment of the social state. I argue, by analysing ethnographic material and political discourses, that these contexts, on the one hand, rearticulate old forms of ethnic and cultural nationalism and, on the other hand, create new images and symbols of an open civic society and immigration country. There are ‘playful’ forms, such as campaigns of nation branding, that symbolically include the ‘productive’ and ‘useful’ immigrant into the national project. Moreover, such campaigns serve to legitimatise the downsizing of the national state that – according to a neoliberal attitude – relies on a new community spirit of entrepreneurial, ‘activated’ citizens who ‘help themselves’. Thus, focusing on these pluralised renationalisation processes makes evident how polyvalent ‘the national’ still is. It can be employed by those who attempt to ‘reunite’ the East and West Germans, by businesses to sell their goods and ideas and by almost any political orientation, be it right‐wing or left‐wing.  相似文献

The Devonian Antrim Shale is an organic‐rich, naturally fractured black shale in the Michigan Basin that serves as both a source and reservoir for natural gas. A well‐developed network of major, through‐going vertical fractures controls reservoir‐scale permeability in the Antrim Shale. Many fractures are open, but some are partially sealed by calcite cements that retain isotopic evidence of widespread microbial methanogenesis. Fracture filling calcite displays an unusually broad spectrum of δ13C values (+34 to ?41‰ PDB), suggesting that both aerobic and anaerobic bacterial processes were active in the reservoir. Calcites with high δ13C values (>+15‰) record cementation of fractures from dissolved inorganic carbon (DIC) generated during bacterial methanogenesis. Calcites with low δ13C values (13C values between ?10 and ?30‰ can be attributed to variable organic matter oxidation pathways, methane oxidation, and carbonate rock buffering. Identification of 13C‐rich calcite provides unambiguous evidence of biogenic methane generation and may be used to identify gas deposits in other sedimentary basins. It is likely that repeated glacial advances and retreats exposed the Antrim Shale at the basin margin, enhanced meteoric recharge into the shallow part of the fractured reservoir, and initiated multiple episodes of bacterial methanogenesis and methanotrophic activity that were recorded in fracture‐fill cements. The δ18O values in both formation waters and calcite cements increase with depth in the basin (?12 to ?4‰ SMOW, and +21 to +27‰ PDB, respectively). Most fracture‐fill cements from outcrop samples have δ13C values between ?41 and ?15‰ PDB. In contrast, most cement in cores have δ13C values between +15 and +34‰ PDB. Radiocarbon and 230Th dating of fracture‐fill calcite indicates that the calcite formed between 33 and 390 ka, well within the Pleistocene Epoch.  相似文献

The question whether there exists an interaction between ‘science’ (foreign text ignored) and ‘technology’ (foreign text ignored, esp. foreign text ignored) in Greek and Roman antiquity is discussed controversially until today. Especially representatives of the philologies strictly deny any form of relation, whereas modern scientists tend to take for granted that the current interaction between (exact) natural sciences and technology has always existed, at least since the beginning of real natural science founded by the ancient Greeks. This paper shows that both parties are right — at least in a certain way. Following current terminology and contents of ‘science’ and ‘technology’ there had been such an interaction — particularly with mathematics as linking element in so far as in antiquity especially foreign text ignored (mechanics) was regarded as applied mathematics and not as science. The strong interaction between pure mathematics and such fields of applied mathematics (namely mechanical technology) based on the fact that technological (mechanical) artefacts were properly constructed mathematically. Some of them are mentioned in this paper (astrolabes and sundials, waterclocks, tools and machines — especially lifting gears, bucket elevators, guns, pneumatic tools —, architecture of temples); in so far the supporters of an interaction between science and technology are right. However, the post-Aristotelian Greeks and Romans did not consider mathematics to be part of ‘science (of nature)’ as the post-kantian exact scientists do. Mathematics to them was a mere ‘art’ — consequently, in the mentioned cases there had been an interaction between ‘arts’ and of course not between ‘science’ and ‘art’ (technology); and in so far those are right who deny an interaction between natural science and technology. This shows that the contrariety of the answers to the question depends on the different terminology chosen. Following the current understanding of ‘exact natural science’ the answer is: yes; following the conception of ‘science’ in the self-understanding of Greek and Roman antiquity the answer is: no — and this is right as well! The reason for this apparent contrariety are just the different meanings and contents of ‘science (of nature)’ in antiquity and modern times.  相似文献

Twenty‐six wall painting fragments and some plaster, ‘intonachino’ and stucco samples, discovered at Iulia Concordia, have been studied by different analytical techniques to gain information about the pigment nature and the composition of the materials. The presence of calcite, dolomite and aragonite allow the distinction of four groups of wall samples varying in the nature of pigments and in the application technique. These differences can be attributed to different execution times or, more probably, to the arrangement of the rooms in the building structure. The nature of the pigments found in the Thermae of Iulia Concordia appears similar to that found in other Roman villas of Venetia et Histria, with the use of precious pigments such as Egyptian blue and cinnabar.  相似文献

Occipital bone lesions on an Iron Age horse cranium from the burial mound of Arzhan 1, Tuva, Central Asia, are described and interpreted. Cavitations around the nuchal ligament attachment site on the skull are interpreted as foci of inflammation and necrosis following local infection. It is suggested that the pathology represents a case of ‘poll‐evil’, most likely due to a bacterial infection. The significance of such an interpretation is discussed, including its implications for disease ecology and the possible infection risks to contiguous animal and human communities of the first millennium BC in Central Asia.
