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
Studio Retrospettivo Sulla Microcitosi Nel Cane. Aspetti Clinici e di Laboratorio
No full textMicrocytosis sometimes associated to hypochromia is a laboratory finding which occurs in several disorders. The ethiopathogenesis is referred to a modification of hemoglobin production, which induces in turn a reduction of the mean corpuscolar volume of erythrocytes (RBC). In this view microcytosis can be considered a compensatory mechanism in order to re-establish the correct proportions between the RBC volume and hemoglobin content. The several disorders in relationship to microcytosis have a common iron metabolism de- arrangement. The aim of this study was to establish the incidence of microcytosis in a large canine population considering 2,301 complete blood count. Moreover, the frequency of disorders occurring in microcytemic dogs and the relationship with the modification of other hematological parameters have been investigated
Retrospective and observational investigation of canine microcytosis in relationship to sex, breed, diseases, and other complete blood count parameters
No full textThe prevalence of canine microcytosis, detected as reduced mean corpuscolar volume (MCV) by impedance cell counter was investigated retrospectively in relationship to sex, breed, diseases, and other blood count parameters. One thousand and twelve (1,012) canine medical records with complete blood count (CBC) were evaluated for MCV results. CBCs were performed using impedance cell counter and stained blood smears for leukocyte differential count, erythrocyte morphology, and platelet estimation. Statistical analysis included both comparative and descriptive inves- tigations in dogs showing microcytosis (MICRO) versus dogs with normal MCV (control, CTR). MCV was lower than the reference range in 8.5% of medical records (86/1,012). Only 47.7% of MICRO dogs were affected by different degrees of anemia. In MICRO dogs, thrombocy- tosis was present in 19.8%, while 16.3% showed thrombo- cytopenia, and mild leukocytosis was found in 30.2%. Statistical analysis showed significant difference about sex and breeds in MICRO vs. CTR dogs while different disorders did not affect the MICRO vs. CTR dogs; few CBC parameters such as erythrocyte count, hematocrit, and red cell dimension width were both significantly related to MCV of MICRO dogs and between CTR and MICRO dogs. Multivariate hierarchical cluster analysis showed significant difference among clusters considering platelets and displayed a subgroup of patients in MICRO dogs. Microcytosis detected at low rate in CBC of clinical records is not always related to anemia. The comparison in MICRO and CTR dogs showed a significant difference for most blood count parameters dealing with erythrocytes and leukocytes but not for platelets
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
