Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Recumbent folds and cleavage of tavricheskaya series as structures of early extension stage in the Crimean Mountains
No full textReview of the data on strain fields of Mesozoides of Northeast of Asia obtained by kinematic method
No full textReconstruction has been made, the data have been summarized and analyzed, which characterize the strain fields of different areas of Mesozoides of Northeast of Asia (Verkhoyano-Kolymian folded area). Strain fields of the North Kharaulakh and Arga-Tas ridge have been investigated based on area kinematic mapping; for internal areas (Middle Verkhoyania and Cherskogo zone) direct and indirect published data on fault kinamatics have been attracted. Discrimination of strain fields responsible for production of basic folded structure as well as pre- and post-folding fields has been carried out. Orientations obtained for axes of the main stresses describe multistage spatially heterogeneous conditions of Mesozoides deformation under conditions of pressure, plastic and fragile tension and, to less extent, displacement. Pre-folding stretching has been found in the Verkhoyan series of the North Kharaulakh; conditions of post-folding fragile tension are widely distributed in different domains of the Cherskogo zone. Deformational conditions being reconstructed for North Kharaulakh and Arga-Tas ridge coincide with contemporary field of strains detected by seismological data
Transverse deformation zonality values and palinspastic reconstructions of Carpathians on the base of structural analysis of folding
No full textOn the basis of the structural analysis of folds the complex deformation profile in the Hust—Ivano-Frankivsk (central part of Ukrainian Carpathians) transsection is constructed. It characterises distribution of non-coaxial flow deformation on a spectrum of parameters: angles of an axis of compression and simple shear, sizes of horizontal compression and deformational ellipses. Horizontal shortening shows a series of peaks over more or less levelled general background of double compression. The most intensive deformation, expressed in the maximum sizes of horizontal and general compression (to 4 times), is dated for area of Internal Nappes (basically the Dukljansky zone) and to the termination of the Krosnensky zone. There are also indications on growth of deformation in back of Internal Nappes and in front of Skibovaya zone. Deformation as a whole goes down to the central part of a profile occupied by Krosnensky zone where conditions of almost horizontal main compression are marked also. Reconstruction of the primary sizes of structural zones along of Hust—Ivano-Frankivsk profile in the interval of Porkuletsky—Skibovoj zones as a result of returning in a initial condition before deformation of non-coaxial flow has increased in 2.4 times, having reached 183 km that it is necessary to consider as the bottom estimation of initial width which should be increased at the expense of components of bend folding. Possibilities which are given by model of non-coaxial flow for reconstruction on the scale of full deep crossing of Carpathians are short estimated for what approach of homogeneous deformation on depth has been used: 2-time size of horizontal reduction, and also angle of an axis of compression 20є are accepted as averages. Obtained contours of the Krosnensky zone of profile DOBRE-3 shows convergence with results of application of a method of the balanced cross-sections
