'The Fields of Britannia: Continuity and Change in the Late Roman and Early Medieval Landscape.
No full textIt has long been recognized that the landscape of Britain is one of the 'richest historical records we possess', but just how old is it? The Fields of Britannia is the first book to explore how far the countryside of Roman Britain has survived in use through to the present day, shaping the character of our modern countryside. Commencing with a discussion of the differing views of what happened to the landscape at the end of Roman Britain, the volume then brings together the results from hundreds of archaeological excavations and palaeoenvironmental investigations in order to mappatterns of land-use across Roman and early medieval Britain. In compiling such extensive data, the volume is able to reconstruct regional variations in Romano-British and early medieval land-use using pollen, animal bones, and charred cereal grains to demonstrate that agricultural regimes variedconsiderably and were heavily influenced by underlying geology. We are shown that, in the fifth and sixth centuries, there was a shift away from intensive farming but very few areas of the landscape were abandoned completely. What is revealed is a surprising degree of continuity: the Roman Empiremay have collapsed, but British farmers carried on regardless, and the result is that now, across large parts of Britain, many of these Roman field systems are still in use
The fields of Britannia Continuity and Discontinuity in the pays and regions of Roman Britain
No full textThe transition from Roman Britain to medieval England and Wales clearlysaw profound changes in society and landscape, with the large-scaleabandonment of the settlements most closely associated with Romanitas –villas and towns – and the emergence of new architectural styles, burial rites,and other material culture of Germanic character. These changes in thearchaeological record suggest profound social dislocation for the higherechelons of society, but have deflected attention away from what may havebeen a very different story for the majority of the rural population. This articleoffers a preliminary description of the results of the Fields of BritanniaProject, which is examining the potential for continuity and discontinuity inagricultural landscapes across the different regions of Roman Britain. Threestrands are explored: the palaeoenvironmental sequences that record howpatterns of land use changed over time, the relationship between excavatedRomano-British field systems and those of the medieval period, and the waysin which settlement patterns evolved. All three point to considerablepotential continuity and a lack of evidence for large-scale post-Romanabandonment of the rural countryside in lowland areas
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
