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
New data on Reticulitermes urbis and Reticulitermes lucifugus in Italy: are they both native species?
Full text linkIn Italy, three species of subterranean termites in the genus Reticulitermes exist: the native R. lucifugus (Rossi), the North-
American R. flavipes (Kollar), and R. urbis Bagneres, Uva et Clement. R. urbis is a recently described species, that is suspected to
have been introduced from the Balkans to France and Italy, where until the present study it had been found only in a few urban
areas. The distribution of R. urbis in Italy is still poorly understood. We collected 22 Reticulitermes samples in 17 Italian localities
in order to define better the distributions of R. urbis and R. lucifugus and to determine whether R. urbis can be found also in natural
environments. We identified termite species by sequencing a portion of the mitochondrial gene encoding for the cytochrome
oxidase subunit II (COII), that we also used for the construction of haplotype networks and for phylogenetic analysis. We found
R. urbis in three urban areas in the north, and in seven natural areas in the south. So, in Italy, R. urbis is more diffused than previously
thought. The same pattern of distribution, restricted to urban areas in the north and including also natural environments in
the south, is seen in the native R. lucifugus, and may be explained by the climatic requirements of these species. The lower genetic
variability of R. urbis observed in Italy and France, compared with the Balkans, may be explained without implying an introduction
by man. Moreover, many insect species exist with a range similar to that of R. urbis. For these reasons, we think that R. urbis
could be native in Italy
Detection of postoperative relapsing/residual cholesteatomas with diffusion-weighted echo-planar magnetic resonance imaging
No full textPurpose: To assess the capability of echo-planar diffusion-weighted magnetic resonance imaging (MRI) (EPI-DWI) in diagnosing relapsing/residual cholesteatomas after canal wall-up mastoidectomy. Materials and Methods: In a blinded study design, we investigated with MRI, including standard spin-echo sequences, 18 patients evaluated with clinical examination and computed tomography (CT) Suspected for relapsing/residual cholesteatoma 7 to 19 months after a canal wall-up mastoidectomy. Images were evaluated by two radiologists blinded to patients' identities. CT findings. and clinical data set, who decided in a consensus agreement whether there was a pathologic signal increase in the petrous bone in a single-shot EPI-DWI sequence. All the patients underwent a second tympanoplasty or revision surgery of the mastoidectomy cavity within 15 days after magnetic resonance investigation. Sensitivity, specificity, and predictive values were evaluated separate]), for standard sequences and EPI-DWI. Results: In EPI-DWI, five of six patients with cholesteatoma showed a bright signal, whereas those patients with a noncholesteatornatous tissue showed no anomalies. The only misdiagnosed cholesteatoma was a pearl 2 rum in diameter. Sensitivity, specificity, and positive predictive values, and negative predictive values of EPI-DWI in diagnosing relapsing/residual cholesteatomas were 86, 100, 100, and 92%, respectively. Conclusion: EPI-DWI may be a useful tool in differentiating between cholesteatomatous and noricholesteatomatous tissues after closed cavity mastoidectomy. Further investigations are, however, required to establish the practical utility of EPI-DWI on larger series as a screening modality in the follow-up after closed cavity mastoidectomies
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
