Model metadata report for the GSI3D model of the superficial geology of the ground seaward of the Drigg Low Level Waste Repository Site, West Cumbria
Full text linkThis report describes the GSI3D model of the superficial geology of the ground seaward of the Drigg Low Level Waste Repository site, West Cumbria. This geological model is based on the GSI3D geophysical model described in IR/12/071:
Callaghan, E, Kearsey, T, Finlayson, A and Auton, C.A. 2012. Model metadata repport for the GSI3D model of shallow geophysical surveys of the ground seaward of the Drigg Low Level Waste Repository Site, West Cumbria. British Geological Survey Internal Report, IR/12/071. 16pp.
The geophysical model was built to show resistivity characteristics of Quaternary sequences overlying sandstone bedrock and was commissioned by the National Nuclear Laboratory (NNL) for Low Level Waste Repository Ltd (LLWR) and is Commercial in Confidence.
The superficial geological model is not Commercial in Confidence
Metadata report for the Eddleston Water Floodplain GSI3D model
Full text linkThis report describes the work undertaken to characterise the shallow subsurface geology (Quaternary) at Eddleston in the Scottish Borders. In order to produce the GSI3D model the site was re-surveyed, trial pits were excavated, boreholes sunk and a series of geophysical surveys were undertaken.
The three dimensional model is part of a study including hydrogeology and soil hydrology to assess the impact of flooding within the Eddleston Water floodplain
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The sand and gravel resources of the country around Redgrave, Suffolk : description of 1:25,000 sheet TM 07 and part of TM 08
Full text linkThe geological maps of the Institute of Geological
Sciences, pre-existing borehole information, and 118
boreholes drilled for the Industrial Minerals Assessment
Unit form the basis of the assessment of the sand and
gravel resources of the country around Redgrave,
Suffolk.
All the deposits in the district that might be potentially
workable for sand and gravel have been investigated
and a simple statistical method has been used to estimate
the volume. The reliability of the volume estimates
is given at the symmetrical 95 per cent probability level.
The 1:25 000 map is divided into six resource blocks,
containing between 11.2 and 22.9 km2 of sand and
gravel. For each block the geology of the deposits is
described, and the mineral-bearing area, the mean thickness
of overburden and mineral and the mean gradings
are stated. Detailed borehole data are also given. The
geology, the position of the boreholes and the outlines of
the resource blocks are shown on the accompanying map
Dalcharn
No full textThe sequence of sediments exposed in the stream sections at this site includes interglacial organic
·deposits which are both underlain and overlain by till. Although the deposits are undated, the sequence is remarkable for the detail of information it has yielded on the Quaternary history of the Inverness area and the potential it holds for providing further elaboration of this record
