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
Cohomology of Compact Hyperkähler Manifolds.
No full text. Let M be a compact simply connected hyperk ahler (or holomorphically symplectic) manifold, dim H 2 (M) = n. Assume that M is not a product of hyperkahler manifolds. We prove that the Lie algebra so(n \Gamma 3; 3) acts by automorphisms on the cohomology ring H (M ). Under this action, the space H 2 (M) is isomorphic to the fundamental representation of so(n \Gamma 3; 3). Let A r be the subring of H (M) generated by H 2 (M ). We construct an action of the Lie algebra so(n \Gamma 2; 4) on the space A, which preserves A r . The space A r is an irreducible representation of so(n \Gamma 2; 4). This makes it possible to compute the ring A r explicitely. 1. Introduction. Here we give a brief introduction to results of this paper. The subsequent sections are independent from the introduction. The main object of this paper is cohomology of compact hyperkahler manifolds. A hyperkahler manifold (see Definition 2.1 for more precise wording) is a Riemannian manifold M equi..
Hyperkähler embeddings and holomorphic symplectic geometry II
No full textthis paper we recall the definitions and results of the first part ([V-pt I]). By Calabi-Yau theorem, the holomorphically symplectic Kahler manifolds can be supplied with a Ricci-flat Riemannian metric. This implies that such manifolds are hyperkahler (Definition 1.1). Conversely, all hyperkahler manifolds are holomorphically symplectic (Proposition 2.1). For a closed analytic subvariety S of a holomorphically symplectic M , one can restrict the holomorphic symplectic form of M to the Zarisky tangent sheaf of S. If this restriction is non-degenerate outside of singularities of S and the same is true for the set of singular points of S, this subvariety is called non-degenerately symplectic (Definition 2.2). Of course, non-degenerately symplectic subvarieties are of even complex dimension. The hyperkahler manifold is endowed with the canonical SU(2)-action in this cohomology space. Fix an induced complex structure on a hyperkahler manifold M . Let N be a closed analytic subset of M . Then N defines a cycle [N ] in cohomology of M . Denote the Poincare dual cocycle by hNi. In [V-pt I] we proved that if hNi is SU(2)-invariant then N is non-degenerately symplectic (Theorem 2.2 of [V-pt I]). Take a generic element M 0 in a given deformation class of compact holomorphically symplectic Kahler manifolds. Then all integer (p; p)-cycle
