Bronze Age Field System at Tower’s Fen, Thorney, Peterborough: Excavations at ‘Thorney Borrow Pit’ 2004-2005
No full textArchaeological excavation of about 11ha of land at Tower's Fen, Thorney, Peterborough (England), investigated part of an extensive pattern of ditched enclosures and fields associated with several waterholes and two ponds. One large pit, which may have been a waterhole, yielded Early Bronze Age pottery and is radiocarbon dated to the terminal 3rd millennium BC. Two other dates from the ponds came out at around 1500-1300 BC. The other features were probably also Middle to Late Bronze Age although the limited quantity of pottery was not datable precisely. Waterlogged material recovered from the deeper features included most of an unusual wooden tub or bucket, as well as other pieces of worked wood. The palaeo-environmental evidence from pollen, plant macro-fossils, insects and charred plant remains indicated that the land supported a mosaic of woodland, scrub, arable fields, meadow and short grazed grassland. A wide variety of trees was present, particularly wet-loving species such as willow and alder, and there was abundant evidence for coppicing. Nearby excavations at Pode Hole, and the wider picture provided by plotted cropmarks, indicate that the site formed part of an extensive prehistoric landscape. It is suggested that the Bronze Age agricultural landscape developed piecemeal and was based upon a mixed arable and pastoral economy. This contrasts with Fengate and other landscapes of this period where large-scale land divisions have been related to intensive livestock management. The sparse evidence for contemporaneous settlement is typical of many sites of this period
An Iron Age and early Roman farmstead at Calvestone Road, Cawston, near Rugby: excavations in 2012
No full textA programme of archaeological investigation was undertaken by Cotswold Archaeology (CA) prior to housing development to the east of Calvestone Road, Cawston, on the outskirts of Rugby. The work comprised an archaeological excavation over three areas followed by a watching brief on parts of the site not subject to excavation. In Area 1 lay an Iron Age subrectangular enclosure whose ditch had been re-cut on at least three occasions. The enclosure contained evidence for an Iron Age farmstead, including a possible roundhouse. Areas 2 and 3 also revealed evidence of occupation during the Iron Age. Later, in the 1st century AD, the site was remodelled with the laying out of a series of larger enclosures and the development of a trackway. The site was abandoned during the Roman period with no evidence for continued occupation beyond c AD 200. Medieval and post-medieval furrows indicate that later the area was laid down to arable.This report presents the results of the excavation and places them within the context of settlement, the economy and the environment of the Iron Age and Roman periods. The likely function of each feature and structure encountered is considered and compared with other Iron Age and Roman sites
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
