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
The Welsh soldier: 1283-1422
No full textThe present thesis is a study of the reality – and the myth – of the ‘Welsh soldier’ in the later middle ages. The final defeat of the Princes of Gwynedd in 1283 was formalised by the division of the principality of Gwynedd and the ‘feudalisation’ of its territory set out in the statute of Wales proclaimed at Rhuddlan in 1284. As Morris long ago demonstrated, and as Davies and others have since reaffirmed the ‘wars of independence’ – at least in the thirteenth century – were conducted as much between Welshmen as between ‘the Welsh’, the Marchers and the English crown. The picture of Edward I’s pragmatism driven by ‘imperial’ principle – ironically achieving Llywelyn ap Gruffudd’s aim of taking Wales into the ambit of the feudal and political structure of England – without Llywelyn painted by Glyn Roberts is appropriate.1 The integration of Welshmen into Edward I’s military machine was swift, but required innovations of military organisation, chiefly, the Commission of Array. Most Welshmen served at a low level in English armies, as archers, and consequently, are far harder to trace as individuals before the regular survival of full muster accounts in the years after 1369.though global figures can be deduced more readily for the armies of Edward I, Edward II and Edward III, more precise detail cannot. Despite this, patterns of the service of Welshmen, both from the Shires of the principality of Wales and the Welsh March can be generally described over the period covered by this thesis.The concentration of military historians on the formation of royal armies has downplayed the role of military lordship and its importance in the March of Wales. Similarly, while the events of the Glyn D?r rebellion (1400-1410) are well understood, and the consequences of the rebellion on Welsh society have excited some interest, the immediate impact on the Welsh as soldiers has not been fully explored. The place of the Welsh at the battle of Agincourt provides a bridge between the chronological spine of this thesis and the consideration of what might be termed the cultural impression of the medieval Welsh soldier. Thanks largely to Shakespeare’s depiction of Captain Fluellen in Henry V (1599) the Welsh are inextricably linked with this battle, though contemporary evidence suggests the sum of their involvement was extremely limited. Ironically perhaps, in fifteenth century Welsh culture, Agincourt is the silent battle; uniquely there are no poetic references to this battle in a culture where war against France and the earlier battles of Crécy and Poitiers were staple metaphors for the prowess of individuals and as a source of patronage to the bards themselves. The image of Welshmen at war, and particularly, their skill with the longbow, appears to owe much to Gerald of Wales whose accounts of the men of Gwent as archers in the twelfth century has become the province of folklore rather than a reflection of historical reality. There is a striking difference between the Welsh account of their experience at war and the perspective of outsiders. Fundamentally this was because most external commentators saw the Welsh as an undifferentiated mass. Our evidence for the corresponding Welsh view is based upon literature praising the actions of individuals. The majority of their opponents, in Scotland and in France, but also in much of England, the only Welshmen who would ordinarily be encountered were soldiers. The difference in impression was preserved by later observers and the staple depiction of the Welsh as primitive and backward, ‘Wild men from the woods’ in the words of the author of the Vita Edwardi Secundi would have been recognisable to the pamphleteers of the seventeenth century who were themselves describing soldiers. The aim of this thesis therefore is to bring together these views of the ‘Welsh Soldier’ to give a better understanding of his role in later medieval warfare, and the place of war in fourteenth and early fifteenth century Welsh society
Ion trap studies of single microparticles: optical resonances and mass spectrometry
Full text link© 2006 Dr. Adam John TrevittMicroparticle experiments conducted using a newly commissioned quadrupole ion trap (QIT) are reported. Single polystyrene microparticles are confined using three dimensional electrodynamic quadrupole fields and characterised by their fluorescence emission and secular frequency measurements. The advantages of this confinement technique are that single particle properties can be measured free from ensemble averaging effects and unperturbed by solvents and (or) substrates.

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
