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
The multivariate analysis of data relating to the durability of medieval window glass
No full textThe present day physical condition of mediaeval window glass varies enormously, the durability of glass being sensitive to both its chemical composition and the environment to which it has been exposed. About 250 specimens of glass, principally from the windows of York Minster and ranging in date from the 12th to 15th centuries, were subjected to quantitative x-ray fluorescence analysis and the results have been correlated to the weathering characteristics of the glass.
Multivariate analysis of the data reveals that several groups of glasses can be identified chemically, and that certain constituent oxides determine the manner in which the glass decays. The relationship between the durability of ancient window glass and the concentrations present of major and minor constituents will be discussed.L'état physique aujourd'hui des vitraux médiévaux varie énormément ;la conservation du verre est aussi sensible à sa composition chimique qu'aux conditions auxquelles il est exposé.
Environ 250 échantillons de vitres principalement des vitraux de York Minster qui s'étalent du Xlle au XVe siècle sont analysés quantitativement par spectrométrie de fluorescence X. Les résultats sont corrélés avec les caractéristiques de détérioration.
En traitant les données par l'analyse multidimensionnelle, on peut distinguer plusieurs groupes par leurs compositions chimiques et remarquer qu'il y a certains oxydes constituants qui déterminent la mode de détériorations des vitres. La corrélation entre la conservation des vitres anciennes et les teneurs des éléments majeurs et mineurs trouvées sera discutée.Cox G. A., Pollard A. Mark.

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
The value of osteology in an historical context: a comparison of osteological and historical evidence for trauma in the late 18th- to early 19th century British Royal Navy
Full text linkTrauma is arguably the most comparative and least ambiguous of palaeopathological lesions. As such, it is an ideal vehicle for exploring the respective contributions and differences between historical and osteological approaches to health in the past. A direct comparison between historical and osteological assemblages is often impossible due to the lack of comparable data, or complicated by the very different perceptions, motivations and pre-occupations of past writers and present researchers. Nevertheless, where genuine opportunities exist to compare and contrast the alternative strands of evidence, it may lead to a much richer and more nuanced understanding of the past. This study uses trauma in the late 18th- to early 19th century British Royal Navy (R.N.) to explore the differences between the two disciplines, and through this process to come to a deeper understanding of the physical effects of a maritime lifestyle on the health of late 18th- to early 19th century R.N. seamen and marines. The 18th- and early 19th century R.N. is one of the best documented institutions of its day, with a large corpus of records accessible in the National Archives in Kew. Recent archaeological excavations in the burial grounds of the three R.N. hospitals of the 18th century in Britain- the Royal Hospitals Haslar in Gosport, Stonehouse in Plymouth and Greenwich Hospital in South-East London- have made available over 300 skeletons of seamen and marines, who were treated but died in these institutions. This study explores the osteological evidence for fractures and joint trauma patterning in 300 of these skeletons. Eighteenth century accounts of the privations and dangers of sailing a fighting ship are well supported osteologically by the presence of 926 fractures and 14 joint dislocations. Osteological trauma patterning was compared with historical data collated from the Haslar and Plymouth Hospital musters (1792-1824) and Entry Books of Greenwich Hospital (1749-1765). The most probable aetiology of injuries was explored using insights from modern medical and forensic research, and 18th century sea surgeons' journals. Falls accounted for a very high proportion of injuries in both datasets, as did crush injuries, and to a much lesser extent, battle trauma. Extremely high rates of nasal fractures, Bennett's fractures of the first metacarpal, and anterior rib fractures in the skeletal assemblages strongly suggest very high rates of casual interpersonal violence. Interestingly, these injuries were very seldom recorded in either sea surgeon or hospital records, possibly due to seamen's fear of punishment for transgressing official naval regulations against fighting. Several unusual fractures (such as Shepherd's fractures of the talus, and third metacarpal avulsion fractures) and bony modifications (such as shallow and unstable hip and shoulder joints, os acromiale and Eagle's syndrome) appear to be the consequences of engaging in a maritime lifestyle, often beginning in childhood or adolescence.
