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
Sensitive oxidation state ambivalence in unsymmetrical three-center (M/Q/M) systems [(acac)(2)Ru(mu-Q)Ru(acac)(2)](n), Q=1,10-phenanthroline-5,6-dione or 1,10-phenanthroline-5,6-diimine (n = +, 0, -, 2-)
No full textThe new redox systems [(acac)(2)Ru(u-Q(1))Ru(acac)(2)](n) (1(n)) and [(acac)(2)Ru(mu-Q(2))Ru(acac)(2)](n) (2(n)) with Q(1) = 1,10-phenanthroline-5,6-dione and Q(2) = 1,10-phenanthroline-5,6-diimine were studied for n = +, 0, -, and 2- using UV-Vis-NIR spectroelectrochemistry, and, in part, EPR and susceptometry. The ligands can bind the first metal (left) through the phenanthroline nitrogen atoms and the second metal (right) at the o-quinonoid chelate site. The neutral compounds are already different: Compound 1 is formulated as a Ru-II(mu-Q(1))(center dot-) Ru-III species with partially coupled semiquinone and ruthenium(III) centers. In contrast, a Ru-III(mu-Q(2))(2-) Ru-III structure is assigned to 2, which shows a weak antiferromagnetic spin-spin interaction (J = -1.14 cm(-1)) and displays an intense half-field signal in the EPR spectrum. The one-electron reduced forms are also differently formulated as Ru-II(mu-Q(1))(2-) Ru-III for 1(-) with a Ru-III-typical EPR response and as Ru-II(mu-Q(2))(center dot-) Ru-II for 2- with a radical-type EPR signal at g = 2.0020. In contrast, both 1(2-) and 2(2-) can only be described as Ru-II(mu-Q)(2-) Ru-II species. The monooxidized forms 1(+) and 2(+) show very similar spectroscopy, including a Ru-III-type EPR signal. Although no unambiguous assignment was possible here for the alternatives Ru-II(mu-Q)Ru-0(III), Ru-III(mu-Q)(2-) Ru-IV or Ru-III(mu-Q)(center dot-) Ru-III, the last description is favored. The reasons for identical or different oxidation state combinations are discussed
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
Participation and Conflict Between Local Community and Institutions in Conservation Processes: The Case of Novara Old Town
Full text linkPurpose – The purpose of this paper is to argue the many ways in which the conservation and revitalisation
processes in Novara carried out over several decades are representative not only of the Italian approach to
urban conservation but also of the fruitful relationship between institutional and social bodies.
Design/methodology/approach – Through an exploratory study approach, this paper illustrates how
social actors contributed to the conservation process of Novara Old Town, and documents the regeneration of
two historic complexes, the Castle of Novara and Casa Bossi. To do so, it drew upon content analyses of the
official reports and planning tools and a set of semi-structured interviews conducted with the representatives
of the community organisations and the Municipal Planning Board.
Findings – The study demonstrates the effectiveness of a third actor whose double role entails cooperation and
conflict. The participatory approach applied in these two heritage complexes has proved to be cost-effective
because it is inherently able to effect “planning in the public domain” and address socially sustainable outcomes.
Originality/value – The Italian approach to the conservation of historic cities has been widely
acknowledged as a “good recipe” in the international context. However, little attention has been paid to how
this success story depends on a unique relationship between public bodies and local communities. To fill this
gap, the paper shed light on the historic centre of Novara and two particular heritage complexes in terms of
the relations of different actors in conservation and regeneration processe
