The integral cohomology rings of some p-groups
No full textWe determine the integral cohomology rings of an infinite family of p-groups, for odd primes p, with cyclic derived subgroups. Our method involves embedding the groups in a compact Lie group of dimension one, and was suggested independently by P. H. Kropholler and J. Huebschmann. This construction has also been used by the author to calculate the mod-p cohomology of the same groups and by B. Moselle to obtain partial results concerning the mod-p cohomology of the extra special p-group
Parenchyma abundance in wood of evergreen trees varies independently of nutrients
No full textThe abundance of living cells in wood—mainly as interconnected axial and ray
parenchyma networks—varies widely between species. However, the functional
significance of this variation and its role in plant ecological strategies is poorly understood, as is the extent to which different parenchyma fractions are favored in relation to soil nutrients and hydraulic functions. We analyzed wood tissue fractions of 16 Australian angiosperm species sampled from two nearby areas with similar climate but very different soil nutrient profiles and investigated structure-function links with soil and tissue nutrient concentrations and other plant traits. We expected the variation in parenchyma fractions to influence nutrient concentrations in wood xylem, and to find
species with lower parenchyma fractions and accordingly lower nutrient requirements on lower-nutrient soils. Surprisingly, both axial and ray parenchyma fractions were mostly unrelated to tissue and soil nutrient concentrations, except for nitrogen concentration in stem sapwood. Species from low nutrient soils showed higher fractional P translocation from both leaves and sapwood, but little patterning with respect to tissue nitrogen. While species from high and low nutrient soils clearly clustered along the soil-fertility axis, their tissue composition varied independently from plant functional traits related to construction costs and hydraulic anatomy. Our findings imply that there is considerable variation among species in the nutrient concentrations within different parenchyma tissues. The anatomical composition of wood tissue seems unrelated to plant nutrient requirements. Even though xylem parenchyma is involved in metabolic functions such as nutrient translocation and storage, parenchyma abundance on its own does not directly explain variation in these functions, even in co-occurring species. While parenchyma is highly abundant in wood of angiosperm trees, we are still lacking a convincing ecological interpretation of its variability and role in whole-tree nutrient budgets
Submarine silicic volcanism of the Healy caldera, southern Kermadec arc (SW Pacific): I - volcanology and eruption mechanisms
No full textThe submarine Healy volcano (southern Kermadec arc), with a 2-2.5 km wide caldera, is pervasively mantled with highly vesicular silicic pumice within a water depth of 1,150-1,800 m. Pumices comprise type 1 white-light grey pumice with h30 mm vesicles and weak-moderate foliation, type 2 grey pumice with millimetre-scale laminae, flow banded foliation, including stretched vesicles h55 mm in length, and a minor finely vesicular type 3 pumice. All types are sparsely porphyritic, with undevitrified glassy groundmass (68-70% SiO2), which is microlite and lithic free. Coexisting pyroxenes yield magma temperatures of ~950 °C. Pumice density is h0.5 g cm-3 and vesicularity is 78-83%. Vesicle size distributions for types 1 and 2 pumice, range from ~20 µm to >20 mm, with a strong power-law relation (with d=-2.5-0.4) for vesicles <1-2 mm. Larger vesicles have variable size modes. The vesicle size distribution and packing indicates rapid magma decompression and ascent. Consideration of the pressure dependent, solubility of H2O at a magma temperature of h950 °C and water content of h6 wt%, with pumice petrography and vesicle granulometry, strongly suggests a pyroclastic eruption. Reconstructions of the submarine edifice between water depths of 1,000 and 550 m constrain the ambient hydrostatic pressure to ~6-9 MPa. Pressures >~9 MPa will limit vesicularity to less than the observed 78-83%, whereas pressure <~6 MPa require a more shallower reconstruction of the edifice and larger-volume syn-eruptive collapse. Uniformly high vesicularity is interpreted as evidence of insulation within an eruption column comprising steam and hot pyroclasts. Most pyroclasts cool, condensing and ingesting water into steam-inflated vesicles, and then sink. Progression into pyroclastic mode would expand the eruption column, displace ambient water, reduce the hydrostatic load, and further promote vesiculation and fragmentation. Pyroclasts within the column would quench at these reduced pressures. We argue that Healy eruptions deeper than ~1,000 m cannot be pyroclastic. Volumes for the lower and upper bounds of edifice size are 2.36 and 3.58 km3, respectively, but do not account for intra-caldera pumice fill. These volumes are considered to be predominantly primary eruption output, as shown by a dearth of accessory lithics in all pumice, yielding (at an average 81% vesicularity) eruptive pumice volumes of between 10 and 15 km3. Some pyroclasts may have risen to the sea surface and be a correlative of the sea-rafted Loisels pumice; the latter occurs in some New Zealand Holocene beach sequences and has a estimated age of 590-80 calendar years.<br/

Cold war theology: a controversial religious image of King James VI & I in England and on the Continent in 1603
No full textA former student of James Cameron’s, Ian Hazlett contributes a paper very much in the spirit of his teacher. It considers the afterlife of the King’s (or Negative) Confession, commissioned by James VI of Scotland in 1581 as a clear statement of his Calvinist credentials. By the time he gained the crown of England in 1603 however, his evolving religious views meant it had become a document he sought to distance himself from. Both Protestant and Catholic propagandists and publishers, keen to give a particular picture of the theological sympathies of the new English king, subsequently produced a surprisingly varied selection of versions of the Confession. These sources and what they can tell us about the theology and politics of the day are considered here for the first time in a scholarly study.Publisher PD
Intellectual Property and Innovation: A Framework for 21st Century Growth and Jobs
No full textIn the presence of European Commission Vice-President Neelie Kroes, the Lisbon Council launched Intellectual Property and Innovation: A Framework for 21st Century Growth and Jobs. In this timely report, ten leading European intellectual property thought leaders offer strategic advice on how to enhance the existing intellectual property regime for the digital age – and in turn boost innovation, encourage creativity and generate much-needed growth and jobs. Ian Hargreaves, professor of digital economy at Cardiff University and author of the high-level Digital Opportunity report prepared for UK Prime Minister David Cameron, contributed the Foreword. The study was co-edited by Prof. Hargreaves and Paul Hofheinz, president of the Lisbon Council
Ian McEwan’s Characters in Žižekian Process of Subjectivity A Study of Ian McEwan’s Atonement and Solar
No full textJacques Lacan’s (1901-1981) theory of subjectivity provides literary criticism with an authentic approach to the analysis of characters. Slavoj Žižek, also, supplies his own reading of the Lacanian theory by adding Hegel to the Lacanian Subject and generates his theory of ‘subject in process.’ Taken from Žižek’s words that “the status of the subject is thoroughly “processual”” (Žižek, 2010, p. 232), we have decided to call the Žižekian theory as processual subjectivity. Considering the psychoanalytic significance of the characters in the novels of the renowned British author Ian McEwan, we will apply the Žižekian theory of processual subjectivity on the main characters of Ian McEwan in two of his novels: Solar and Atonement. It is to be proved that this reading can lead to better appreciation and apprehension of characters’ psyche.</p
URI Disambiguation in the Context of Linked Data
No full textThe Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates two popular resources, DBLP and DBpedia, and discusses whether the issues regarding identity management and co-reference resolution have been suitably addressed. We find that a large percentage of authors in DBLP have been conflated, and that disambiguation pages have been incorrectly linked using owl:sameAs within DBpedia. Systems for dealing with these issues are presented, and directions are given for future research
