Bones from extinct Australian marsupials found at Spring Creek, Victoria, and in the Mowbray Swamp, Tasmania, have yielded scattered and anomalously young radiocarbon ages measured on collagen, gelatin or ultrafiltered gelatin. We resampled previously dated material from those two sites and from Mt Cripps, Tasmania, as well as a control sample from Zaglik, Russia, to compare chronologies based on XAD‐2 purified total amino acid fractions and collagen purified by ultrafiltration (UF) or less rigorous methods. Our age from the control site bone gave a similar infinite age, while six out of seven other comparisons yielded radiocarbon ages on total amino acid fractions older than those previously measured on collagen or gelatin. The Palorchestes from Spring Creek yielded a date of >53500 BP. 相似文献

During 2002, the extensive archaeological excavations of the ancient Constância necropolis (Centre of Portugal), dated from 14th–19th centuries, resulted in the exhumation of 151 individuals. Among the several paleopathological cases, a middle‐aged female skeleton with osteolytic lesions in her skull, axial skeleton, upper limbs and femurs was observed. These pathological findings are characterised by an asymmetric pattern with osteolytic focus of distinct size and irregular shape. Some skeletal elements display both osteolytic and osteoblastic lesions. The latter exhibit deposition of fine layers of woven bone. Lesions were observed macroscopically and radiology was used as a complementary method of scrutiny, especially in cases of unclear observation. The case was diagnosed as that of a probable metastatic carcinoma due to the multifocal distribution of the lesions in areas of intense haematopoietic activity, their morphology and some osteoblastic responses, as well as the presence of pathological fractures in the ribs. The skeleton's sex and age at death are in agreement with the proposed diagnostic, constituting the first case of malignant carcinoma detected in non‐identified Portuguese human skeletal remains.

This study is based on the paleaopathology of leprosy on human skeletal remains and the detection of ancient Mycobacterium leprae DNA. Two cases of childhood leprosy were recognized. The first case was in a Roman necropolis at Martellona (Rome, Central Italy), dated to the 2nd to 3rd centuries ce . The skeleton of a child aged 4–5 years, from tomb 162, is the youngest individual in Italy from this time period, with the clear rhino‐maxillary syndrome and other bony changes indicative of leprosy. The second case from a burial at Kovuklukaya, in the Sinop region of Northern Turkey, was from the 8th to the 10th centuries, during the Byzantine era. The endocranium of a 4–5‐month‐old infant with new bone formation—an indication of chronic inflammation—was positive for M. leprae DNA. Infant and childhood leprosy is uncommon today, and there is a scarcity of information in the osteoarchaeological literature of leprosy in the past, especially in children. The significance of these cases is that it adds to an understanding of the history of the disease in the former Roman Empire. It is hoped that over time sufficient data can be obtained to understand the epidemiological dynamics and clinical evolution of leprosy from the ancient period until today.

Ancient Greek is widely regarded as a language with an extraordinary number of so-called “Wackernagel P2 particles” such as γ?ρ, δ(?), and μ?ν, which serve a multitude of discourse functions. From the post-Classical period on, however, these small words gradually lose their importance in discourse and die out. This is reflected in the interest of scholars: while there are many studies on particles in older stages of Greek, not much research has been conducted on the particles in late medieval Greek (LMG; twelfth to fifteenth centuries). At this stage of the Greek language, the P2 particles are acknowledged to no longer be part of the living spoken language. Nonetheless, some of these small words still turn up in texts written in the vernacular. Since most LMG vernacular literature is composed in the metre of the 15-syllabic πολιτικ?? στ?χο? (vernacular prose being extremely scarce in this period), these occurrences are traditionally explained by appealing to metrical and/or stylistic reasons: the particles constitute archaizing relics merely inserted to give a classicizing flavour to the text, or are even used “metri causa”, simply to achieve the required number of syllables. In this note, I present a case-study on the “explanatory” particle γ?ρ (“for”) in the Chronicle of Morea, the best-known verse chronicle of the Greek Middle Ages. I show that γ?ρ is more than a blatant line filler. First, γ?ρ is not at all distributed at random, but consistently occupies P2 and thus obeys the so-called “Law of Wackernagel”, as the particles in Ancient Greek do. Moreover, γ?ρ can still exert a clear discourse function, albeit often a different one than in Ancient Greek. 相似文献

This article looks at the issues facing the regulation of commercial public service broadcasting in Norway. A document analysis of the 2010 renegotiation process to renew TV 2’s public service licence illuminates how a general marketization affects the regulation of the television sector. This process comments on Hallin and Mancini’s model of democratic corporatism in the Nordic countries regarding the power of the state to regulate private media enterprises as cultural institutions. As such, the process of commercialization should include not only the broadcasting sector, but also the political sector. As part of a solution to retain TV 2’s licence agreement, the government effectively had to re‐regulate the cable distribution sector. This case study demonstrates not only the enduring strength and value of the public service institution in a political context, but also the extent to which regulation is guided by technical and economic forces to sustain democratic considerations. 相似文献

ABSTRACTWe investigate the inherent characteristics of 2D basins subjected to vertically propagating P-SV waves using the finite difference approach. The ratio of fundamental frequencies between an inhomogeneous basin (f0) and its equivalent flat layers (fh) is found to be a function of both its outer overall geometry and inner geometric formation. 2D resonance can occur in inhomogeneous basins under certain conditions, and the f0/fh can be used to demarcate deep from shallow basin behaviors. With other conditions remaining the same, changing a basin from homogeneity to inhomogeneity results in a lower f0/fh and makes 2D resonance less likely to occur. 相似文献

Diagenetic iron (oxyhydr)oxide minerals are common precipitates expected in CO2 reservoirs, and these minerals record fluid flow for application to carbon capture and sequestration (CSS). Multiple mineralogy and spectroscopy analyses on a pore to meter scale characterize a well‐exposed, lithologically controlled, iron (oxyhydr)oxides reaction front in the Jurassic Navajo Sandstone. Dolomite is the most prevalent cement (up to 23 area%), followed by only several percent or less of iron (oxyhydr)oxides, kaolinite, illite, and gypsum cements. Bulk geochemistry based on diagenetic mineralogies in the reaction front is compared with the water chemistry from nearby modern spring effluent emanating from the Navajo Sandstone to conclude that similar fluids (i.e., CO2‐charged, saline waters containing hydrocarbons) are responsible for the precipitation. A second comparison of bulk geochemistry and diagenetic mineralogies of the reaction front with data from other abundant Navajo Sandstone concretions in the Spencer Flat region (in south central Utah) shows that reservoir fluids likely vary spatially and temporally in the porous and permeable Navajo Sandstone. CO2 injection into porous and permeable, quartz arenite, saline aquifers will likely result in minor clay and abundant dolomite precipitation that will significantly decrease porosity. 相似文献

Thomas Hobbes in Leviathan presented a paradigm of the social contract that has proven foundational in Western political thought. A proper understanding of the philosopher’s thought is thus of paramount importance. I argue that today’s case for a religiously tolerant Hobbes has missed an important part of the historical record. I first consider an obscure but important document, the second edition of the Humble Proposals. It demonstrates that leading members of a seventeenth century Christian denomination, the Independents, considered a state-enforced confession of faith. Independents are generally seen as tolerant, and one of the arguments for Hobbesian toleration is that Hobbes endorsed them. But the second edition of the Humble Proposals aligns with the possibility in Hobbes that the civil sovereign will impose part III of Leviathan on the Universities and treat its contents as a legally required confession of faith – one that may be necessary for security, and the avoidance of civil war. Hobbes’s endorsement of Independency alone cannot be used to argue that his work leads to religious toleration. The evidence I present reinforces an earlier assessment and alongside other evidence points to the return of the intolerant Hobbes. 相似文献

ABSTRACT Literal biblical interpretation advocates the view that at the outset of the paradise story Adam and Eve were only banned to eat of the tree of knowledge. The present paper challenges this view through an economic, ra-tional choice interpretation and the application of a self-interested decision calculus (model of economic man). I mount the thesis that, on grounds of a rational choice reconstruction, Adam and Eve must have been implicitly banned from the outset not to eat of the tree of life, despite no explicit ban be-ing stated in Genesis. The paper argues for the validity and insightfulness of such a rational choice analysis of the paradise story, which considerably clari-fies the conceptual logic and structure of the Eden story. 相似文献
