AbstractThree new ophiuran species, Enakomusium whymanae n. sp., Aspidophiura? seren n. sp., and Ophiotitanos smithi n. sp., and an unnamed specimen assignable to the genus Dermocoma are described from the Callovian to Oxfordian Oxford Clay Formation of Great Britain. These determinations are based on new finds and a critical reassessment of historic specimens. The Oxford Clay ophiuroids represent two loose assemblages, one from the middle Callovian Peterborough Member and the other from the lower Oxfordian Weymouth Member. Both assemblages accord well with coeval midshelf mud bottom ophiuroid communities in terms of taxonomic composition and relative abundance of taxa. The British Oxford Clay ophiuroids are particularly significant as they are one of the rare instances where multiple species are represented, almost exclusively, by exceptionally preserved articulated skeletons. This provides an important window into the understanding of mid-Upper Jurassic ophiuroid paleobiology.

AbstractSouth Brae Oilfield lies at the western margin of the South Viking Graben, 161 miles northeast of Aberdeen. Oil production began in July 1983 from a single platform located in 368 ft of water. The field originally contained 312 MMBBL of recoverable reserves, and in May 1990, cumulative exports of oil and NGL reached 219 MMBBL. The reservoir lies at depths in excess of 11800 ft TVSS, has a maximum gross hydrocarbon column of 1670 ft, and covers an area of approximately 6000 acres.The reservoir is the Upper Jurassic Brae Formation which is downfaulted against tight sealing rocks of probable Devonian age at the western margin of the field. The other field margins are constrained by a combination of structural dip and stratigraphic pinchout.The reservoir is capped by the Kimmeridge Clay Formation, which is also the source of the oil.

The following pages are based on the last six months of 1948 which the writer spent in England, France and Italy. During this period Marshall aid had begun to bear certain fruit. On the other hand the international situation, already bad at the opening of the period, had deteriorated cumulatively as time passed. The Berlin deadlock, a symbol of the will of East and West, continued as before; and not even the beginning of a solution was reached at the United Nations assembly in Paris in die autumn. All over Europe people were preoccupied widi the economic crisis; but also by the direat of a new war. A military committee composed of Great Britain, France and Benelux was formed in the autumn under the chairmanship of Marshal Montgomery. There remained problems about this committee's effectiveness as well as about the extent to which other proposals for Western union were practicable at present. While in each country in Western Europe common people and politicians are talking more about union than ever before, in practice separatist tendencies in each shrunken western nation are still at work and travel to, or independent contact with, neighboring countries is a far more difficult business today than it was in 1939.

The 19Th Century

The previously ignored model of Greek colonisation attracted numerous actors from the 19th century British empire: historians, politicians, administrators, military personnel, journalists or anonymous commentators used the ancient paradigm to advocate a global federation exclusively encompassing Great Britain and the settler colonies in Canada, Australia, New Zealand and South Africa. Unlike other historical templates, Greek colonisation could be viewed as innovative and unspent: innovative because of the possibility of combining empire and liberty and unspent due to its very novelty, which did not contain the ‘imperial vice’ the other models had so often shown and which had always led to their political and cultural decline.

Political Pamphlets

This article investigates patterns of personal pronoun usage in four texts written by women about women's rights during the 1790s: Mary Wollstonecraft's A Vindication of the Rights of Woman (1792), Mary Hays' An Appeal to the Men of Great Britain (1798), Mary Robinson's Letter to the Women of England (1799) and Mary Anne Radcliffe's The Female Advocate (1799). I begin by showing that at the time these texts were written there was a widespread assumption that both writers and readers of political pamphlets were, by default, male. As such, I argue, writing to women as a woman was distinctly problematic, not least because these default assumptions meant that even apparently gender-neutral pronouns such as I, we and you were in fact covertly gendered. I use the textual analysis programme WordSmith to identify the personal pronouns in my four texts, and discuss my results both quantitatively and qualitatively. I find that while one of my texts does little to disturb gender expectations through its deployment of personal pronouns, the other three all use personal pronouns that disrupt eighteenth century expectations about default male authorship and readership.

I beg leave to offer to your Lordship and the Society a Description of a Roman Altar lately dug up in the neighbourhood of Aldston Moor, in Cumberland, near a military road, and not far from a great Roman station. The altar is three feet high, sixteen inches wide, and eight thick. It is divided into three compartments, the capital, the square or plane, and the base. On the top is an oval cavity one inch and a half deep, and about nine over by six, in which the wine, the frankincense, and the fire were placed, and was called Thuribulum, the censer, or the focus; but this hole is not on all the Roman altars found in Great Britain. On the sides however of the one I am describing are two bass-reliefs, representing on one part the infant Hercules strangling two serpents (as he is seen on a silver coin of Croton in Italy), and on the other the god in all his strength about to combat the serpent in the garden of the Hesperides (as he appears on a coin of Geta struck at Pergamus).

Psathyrella typhae (Kalchbr.) Pearson & Dennis forms small basidiomata (mushrooms) and Sclerotium hydrophilum Saccardo in Rothert numerous minute sclerotia at the base of senescent shoots of Typha latifolia L. To assess how the two might compete in nature, isolates of these fungi were paired on autoclaved leaf segments of T. latifolia and incubated at 15 and 25 °C. The relative abundance of each species in the segments was determined by macerating the leaf tissues and then transferring fragments of macerate to microplates containing two types of media: one conclusively demonstrated the presence of P. typhae while the other demonstrated the presence of S. hydrophilum. Relative numbers of microplate wells showing positive reactions for each species on each medium indicated the proportion of the segment occupied following single and paired inoculations. These data demonstrated that competition was asymmetric, with P. typhae the stronger competitor at both temperatures, and uninhibited by the presence of S. hydrophilum. In contrast, S. hydrophilum was competitively excluded by P. typhae.

ABSTRACTCharacterizing the taxonomic diversity of a microbial community is very important to understand the roles of microorganisms. Next generation sequencing (NGS) provides great potential for investigation of a microbial community and leads to Metagenomic studies. NGS generates DNA fragment sequences directly from microorganism samples, and it requires analysis tools to identify microbial species (or taxonomic composition) and estimate their relative abundance in the studied community. However, only a few tools could achieve strain-level identification and most tools estimate the microbial abundances simply according to the read counts. An evaluation study on metagenomic analysis tools concludes that the predicted abundance differed significantly from the true abundance. In this study, we present StrainPro, a novel metagenomic analysis tool which is highly accurate both at characterizing microorganisms at strain-level and estimating their relative abundances. A unique feature of StrainPro is it identifies representative sequence segments from reference genomes. We generate three simulated datasets using known strain sequences and another three simulated datasets using unknown strain sequences. We compare the performance of StrainPro with seven existing tools. The results show that StrainPro not only identifies metagenomes with high precision and recall, but it is also highly robust even when the metagenomes are not included in the reference database. Moreover, StrainPro estimates the relative abundance with high accuracy. We demonstrate that there is a strong positive linear relationship between observed and predicted abundances.

This chapter examines whether status concerns lead decision makers to value status more highly by looking at three separate sets of decisions: Russia's decision to aggressively back Serbia in the 1914 July Crisis, Britain's decision to collude with Israel and France in launching the 1956 Suez Crisis, and Gamal Abdel Nasser's 1962 decision to intervene in the Yemen Civil War (and continue to escalate through the rest of the decade). These cases broadly substantiate the patterns found in the Weltpolitik case—decision makers tend to value status more highly due to status concerns—while highlighting the plausibility of several new mechanisms. They also show that status concerns are not confined to European countries, great powers or states in the pre-World War I era. Finally, they reveal the other side of status concerns: state behavior designed to salvage or defend status rather than increase it.
