The excellently preserved skeleton of a juvenile from the Early Hungarian Period (10th century AD), recently excavated in Gnadendorf (Lower Austria), displays typical symptoms of Type II congenital ‘Klippel‐Feil syndrome’ (KFS): fused cervical vertebrae 2 and 3, and fused thoracic vertebrae 2 and 3. Other features observed in this skeleton clinically reported for KFS include a basilar impression and a spina bifida occulta. The bilateral symmetrical hypoplasia of the basilar part of the occipital bone is probably also linked to this syndrome, as well as the constricted external acoustic meati, which almost certainly led to hearing impairment. A cranial lesion and its possible consequences are discussed in the context of the specific KFS alterations. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Congenital disorders are pathologies rarely found in archaeological cases. In recent years, however, there has been an increase in the number of reported cases, and a growing interest in understanding their development and implication as genetic markers within certain collections. In the central region of Argentina, researchers have begun to focus on issues related to the health of prehispanic populations from a bioarchaeological perspective. Between 1999 and 2012 our research group recovered, by rescue archaeological activities, a total number of 62 individuals from different archaeological sites in the province of Córdoba, from which only three individuals with pathologies classified as congenital were recorded (4.83%). Radiocarbon and contextual information sets these individuals in the late Holocene (2156 ± 86 and 920 ± 20 14C years BP). Hence, this work aims at presenting two pathological conditions deriving from congenital developmental abnormalities that arise during the first three months of pregnancy: (a) Klippel–Feil syndrome (type II) which was suffered by the individuals from the sites of Guasmara and El Vado, and (b) central sagittal fissure of the vertebral body or ‘butterfly vertebra’ as in the case of one individual from La Calera. We also analyse other lesions in these skeletons that may be associated with the conditions mentioned above, and we provide a thorough interpretation from an osteobiographical perspective.

In this article, I analyze the rise of the “Lausanne Syndrome” in Turkish politics during the twenty‐first century through the prism of ontological security theory. The arguments are presented through the examination of the legacy of the “Sèvres Syndrome”, the impact of the Turkish‐Israeli diplomatic break‐up during the 2010s on the Turkish self‐narrative, and the declaration of the second war of independence following the failed coup attempt of 2016. The “Lausanne Syndrome” serves both as a domestic and foreign policy tool, as it relates to Erdo?an’s search for ontological security and geopolitical strategy.  相似文献

This article is situated within the discussion started in 1962 by John Barnes, whose observations on the fluidity of social organization in the Highlands of Papua New Guinea raised the question, what binds together a certain number of individuals belonging to distinct kinship groups? Is it defense of a common territory? Is it participation in initiation rituals which institute a general order between genders and between generations? Or is it, as in the Big-men societies, participation in cycles of ceremonial exchanges which involve all the local groups of a same region? These questions have been discussed by various authors: De Lepervanche (1967–8), A. Strathern (1968, 1970), and Feil (1981, 1984) to mention just a few. The fabric of Baruya society is generated by two principles: direct exchange of women and an elaborate system of male and female initiations. The Baruya share the same culture and the same language with their neighbours and enemies, but they distinguish and define themselves by claiming a common territory conquered at the expense of local groups and by the fact that their women circulate primarily between kinship groups residing on this territory. However, from time to time these two principles are transgressed by individuals or segments of lineages who betray their kinship or tribal solidarities, generating situations which reshape the internal composition of the Baruya tribe and its relationships with its neighbours. I intend by analysing the mechanisms of these betrayals to throw some light on this key-moment in the dynamics of New Guinea Highlands societies.  相似文献

Knowledge of the iron trade in ancient times rests on determining the source of the objects recovered during archaeological excavations. Unfortunately, attributing the origin is not always possible using archaeological tools alone. Trace element data of the ore and the archaeological material (reduction and reheating slags, entrapped slag inclusions from the bloom, bar iron and iron blades) from two Gallo‐Roman iron‐making centres, Les Martys (Montagne Noire) and Les Ferrys (Loiret), were determined using ICP–AES/MS and LA–ICP–MS. The results highlight a continuity of composition that makes it possible to establish a link between the initial ore and the semi‐finished iron products.  相似文献

Over the pre-Columbian sequence, Andean warfare ranged greatly in intensity. This review combines published information on cranial trauma and settlement patterns, which often align and clarify each other, to make an initial assessment of how severely Andean populations were affected by war over time and space. The data speak to a number of major topics in the archaeology of warfare, such as the origin of war, contrasts in state militarism, and changes in the practice of war related to social organization. Although there is considerable regional variation, two large-scale “waves” of escalated conflict that are clearly supported by the cranial trauma and settlement pattern data occurred in the Final Formative (late Early Horizon, 400 BC–AD 100) and the Late Intermediate period (AD 1000–1400).  相似文献

The Early Bronze Age site of RJ‐2, located close to the coastal village of Ra's al‐Jinz on the eastern Omani coast (Niyabat Ra's al‐Hadd), was the focus of archaeological investigations for over two decades. The latest campaigns of excavation unearthed an architectural complex (Building XII) dated to the very end of the Umm an‐Nar period (Final UaN, c.2100–2000 BCE), previously attested on site by poorly preserved remains. This paper presents the remains explored during the most recent fieldwork, focusing on the stratigraphic‐structural sequence and the spatial layout. It also considers the transformations affecting structural evidence and material culture during this period, at both local and regional level, highlighting their significance for a comprehensive assessment of the last occupations related to the Early Bronze Age in south‐eastern Arabia. The paper concludes by showing how the Final Umm an‐Nar phase represents an age of substantial socio‐cultural innovations, which most likely shaped the transition towards the following Wadi Suq period.  相似文献

We report overprinting stable isotope evidence of fluid–rock interaction below two detachment faults along which mantle rocks were exhumed to the seafloor, between the respective landward and seaward limits of oceanic and continental crust, at a Tethyan ocean–continent transition (OCT). This OCT, which is presently exposed in the Tasna nappe (south‐eastern Switzerland) is considered an on‐land analogue of the well‐studied Iberian OCT. We compare our results with the fault architecture (fault core–damage zone–protolith) described by Caine et al. [Geology (1996) Vol. 24, pp. 1025–1028]. We confirm the existence of a sharp boundary between the fault core and damage zone based on isotopic data, but the boundary between the damage zone and protolith is gradational. We identify evidence for: (1) pervasive isotopic modification to 8.4 ± 0.1‰ which accompanied or post‐dated serpentinization of these mantle rocks at an estimated temperature of 67–109°C, (2) either (i) partial isolation of some highly strained regions [fault core(s) and mylonite] from this pervasive isotopic modification, because of permeability reduction (Caine et al.) or (ii) subsequent isotopic modification caused by structurally channelled flow of warm fluids within these highly strained regions, because of permeability enhancement, and (3) isotopic modification, which is associated with extensive calcification at T = 54–100°C, primarily beneath the younger of the two detachment faults and post‐dating initial serpentinization. By comparing the volumetric extent of calcification with an experimentally verified model for calcite precipitation in veins, we conclude that calcification could have occurred in response to seawater infiltration, with a calculated flux rate of 0.1–0.2 m year?1 and a minimum duration of 0.2–4.0 × 104 years. The associated time‐averaged uptake flux of carbon during this period was 8–120 mol m?2 year?1. By comparison with the estimated area of exhumed mantle rocks at the Iberian OCT, we calculate a maximum annual uptake flux for carbon of 2–30 Tg year?1. This is an order of magnitude greater than that for carbon exchange at the mid‐ocean ridges and 0.1–1.4% of the global oceanic uptake flux for carbon.  相似文献

The goal of this article is to test four distinct hypotheses about whether the relative location of an economy affects economic growth and economic well‐being using an extended Solow–Swan neoclassical growth model that incorporates both space and time dynamics. We show that the econometric specification takes the form of an unconstrained spatial Durbin model, and we investigate whether the results depend on some methodological issues, such as the choice of the time span and the inclusion of fixed effects. To estimate the fixed effects spatial Solow–Swan model, we adjust the Arrelano and Bond (1991) generalized method‐of‐moments (GMM) estimator to deal with endogeneity not only arising from the initial income level, as in the basic model, but also from the initial income levels and economic growth rates observed in neighboring economies.  相似文献

Utilising the concept of “geo‐cultural breakthroughs,” the article briefly describes the process of Babi‐Baha'i expansion, tracing the way in which the early Babi movement was later transformed into the Baha'i Faith, and the Baha'i movement itself underwent a succession of massive transformations in the range and diversity of its following. Three main stages and three “worlds” of expansion are identified: (i) an initial “Islamic” stage (1844–c. 1892), in which Babism and the early Baha'i movement were largely confined to the environing culture and society of the Islamic Middle East and its cultural extensions; (ii) an “international” stage (c. 1892–c. 1953), during which Baha'i missionary expansion succeeded in transcending the religion's Islamic roots, in particular by gaining a small but intensely active Western following; and (iii) the present “global” stage from about 1953 onwards, in which the Baha'i Faith has begun to assume the characteristics of a small‐scale world religion, with larger numbers of adherents having been gained, particularly in some parts of Africa, Asia, and Latin America, regions outside of both the religion's original Islamic heartland and the West.  相似文献

The mineralized fracture system that underlay paleo‐fumarole field at Chinkuashih, Taiwan has been exposed by copper–gold mining to depths of about 550 m below the paleo‐surface. Its mineralogy and systematic variations in metal and semimetal (Fe, Cu, As, Sb, Bi, Hg, Cd, Sn, Zn, Pb, Se, Te, Au, Ag) concentrations provide insights into the chemical responses of a magmatic‐vapor phase as it expands through fracture arrays to the surface and discharges as fumaroles associated with more extensive solfatara. At Chinkuashih, following initial sealing of the fractures by silica‐alunite alteration, brittle failure reestablished discharge from an underlying reservoir of magmatic vapor. Crystalline pyrite was deposited first in the fractures and was succeeded and replaced by ‘enargite’ (Cu3(As,Sb)S4) as sulfosalt encrustations (‘sublimate’) on fracture surfaces and in extensional cracks. Subsequent recrystallization resulted in complex exsolution intergrowths with antimony fractionation to the evolving crystal–vapor interface. Heavy metal fractionation between sulfosalt and vapor enriched the vapor phase in heavy metals that subsequently precipitated as complex Bi–Hg–Sn sulfosalts in discrete areas (paleo‐fumaroles) close to the paleo‐surface in a manner analogous to modern‐day fumaroles on active volcanoes such as Vulcano, Italy. As in similar paleo‐fumaroles (e.g., El Indio, Chile and Lepanto, Philippines), the most characteristic reaction sequence is the partial replacement of the early pyrite by enargite and Fe‐tennantite. It is proposed that this reaction tracks the decrease in the pressure of the underlying magmatic‐vapor reservoir because of the sustained discharge of vapor to the surface.  相似文献

Amidst an arguably exhaustive range of studies regarding ethno–politics in post–communist Estonia, this article sets out a new framework derived from Ian Lustick’s model of ethnic control. We argue that one of the key reasons for ethnic peace and stability in Estonia over the past ten years has been a considerable degree of control instituted by the Estonian political community over its sizeable Russian–speaking minority. We analyse this control using Lustick’s three main indicators of segmentation, dependence and co–optation. In addition, we differentiate within each of these categories between structural, institutional and programmatic levels of control measures. Our aim is to place Estonia into a better comparative perspective by bringing to light its particular configuration of control mechanisms. The article concludes with an assessment of what this configuration might mean for future ethno–political developments.  相似文献

This article analyses the drafting of the document eventually printed as the Nineteen Propositions. Section two addresses certain issues regarding the methods and concepts employed in the subsequent analysis, focusing on consensus‐building, constitutional leanings and the drafting of parliamentary declarations in early 1642. Section three examines the origins of the Nineteen Propositions in the draft Declaration of Ways and Means (January 1642) (hereafter cited as the Ways). Section four traces the emergence of the Declaration Concerning Grievances and Remedies (hereafter cited as the Grievances) from the Ways (January–February). Section five examines the junta's efforts to overcome the Lords' prevarication over passing the Grievances (February–May). Section six examines the emergence of the initial draft of the Nineteen Propositions from the Grievances (24–7 May). Section seven analyses the 28 May draft, while section eight explores the amendment of that draft (31 May and 1 June). Section nine examines parliament's abortive attempts to revise the Nineteen Propositions in light of His Majesty's Answer to the XIX Propositions (21 June–2 July). It is concluded that, contrary to the received view, the text of the Nineteen Propositions began to emerge in January rather than May 1642, and that the junta in the Commons rather than the Lords drove this process. The three appendices identify, respectively, the constitutional leanings of the relevant parliamentarians, the parts of the text of the Ways that were repeated in the Grievances, and dates on which the various parts of the final text of the Nineteen Propositions were written.  相似文献

This study deals with the physical–chemical and mineralogical–petrographic investigations (OM, SEM–EDS, EPMA, ICP, XRpD, Mössbauer and IR) conducted on first‐ and second‐firing wasters belonging to two types of incised slipware (sgraffito), manufactured at Castelfiorentino between the late 15th and the early 17th centuries. Raw materials, colouring agents and firing products were analysed in order to establish the production technology of the ceramic coatings, by means of detailed microtextural and chemical investigations. The pottery underwent two firing processes: the firing of the white slip‐coated ceramic body and a further firing after application of the glaze. The homogeneity of the raw materials, white slip and glaze is remarkable, and demonstrates the use of well‐established recipes with a constant supply of raw materials from the same places. Highly efficient kiln management during both firings is revealed by body–glaze interface reactions.  相似文献

Single‐ and two‐phase (gas/water) fluid transport in tight sandstones has been studied in a series of permeability tests on core plugs of nine tight sandstones of the southern North Sea. Absolute (Klinkenberg‐corrected) gas permeability coefficients (kgas_inf) ranged between 3.8 × 10?16 and 6.2 × 10?19 m2 and decreased with increasing confining pressure (10–30 MPa) by a factor 3–5. Klinkenberg‐corrected (intrinsic) gas permeability coefficients were consistently higher by factors from 1.4 to 10 than permeability coefficients determined with water. Non‐steady‐state two‐phase (He/water) flow experiments conducted up to differential pressures of 10 MPa document the dynamically changing conductivity for the gas phase, which is primarily capillary‐controlled (drainage and imbibition). Effective gas permeability coefficients in the two‐phase flow tests ranged between 1.1 × 10?17 and 2.5 × 10?22 m², corresponding to relative gas permeabilities of 0.03% and 10%. In the early phase of the nonstationary flow regime (before establishment of steady‐state conditions), they may be substantially (>50%) lower. Effective gas permeability measurements are affected by the following factors: (i) Capillary‐controlled drainage/imbibition, (ii) viscous–dynamic effects (iii) and slip flow.  相似文献

The assessment of the firing temperature of a prehistoric pottery sample collected from ancient Mesopotamia, Turkey was studied using luminescence techniques. The methods for this estimation involved the observation of the thermal and pre‐dose sensitization with various re‐firing temperatures for both TL and the OSL signals. In the former case, the 110°C TL peak and the rest of the glow curve were used as proxies in this study. In the framework of a first attempt to investigate the impact of grain‐size dependence on the sensitization of the luminescence signals, the aforementioned study was performed with four different pottery grain‐size fractions: (i) less than 60 μm, (ii) 60–90 μm, (iii) 90–180 μm and (iv) 180–250 μm. The results clearly demonstrated the firing temperature mark of ~500°C in for the grain size of 90–180 μm, while—as in the case of the lower grain‐size fraction—a third proxy, the ratio of the pre‐dosed to the thermal sensitization, was seen to indicate the firing temperature. The remaining two grain‐size fractions failed to provide any meaningful results with regard to the firing temperature estimation. The dependence of the TL characteristics on the grain size was explained in the framework of the mixed mineralogy.  相似文献

Abstract

Decisions about the assessment of courses in higher education will influence the structure of the curriculum. Assessment is necessary not only to inform students and staff, but also for external and predictive purposes. The objectives of assessment are both instructional and expressive, while the kinds of skills tested are mainly those of written and oral communication. The incorporation of all these factors into assessment and curriculum design can be facilitated by using tables and diagrams based on educational theory. Unlike other components of the curriculum, assessment continues to play an active role in curriculum development after the initial design stage.  相似文献

The history and procedures of the Smithsonian–NIST programme in the application of instrumental neutron activation to the study of archaeological materials are reviewed. Statistical processing of the resulting analytical data is a major focus of the programme, with attention called to processes of initial group formation. Specific areas of current research emphasis are presented, which build upon the strength of accumulated databases.  相似文献
