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
Detection of histamine 1 (H1) and histamine 2 (H2) receptors on murine spermatozoa by cellular and molecular studies / Nor Azimah Ahmad@Aziz
No full textHistamine is an important biogenic amine in various biological and physiological reactions which mediated by specific histamine receptors. The histaminergic studies in male reproductive system have been revived after the breakthrough of histamine synthesizing enzyme, histidine decarboxylase (HDC) was only found on male germ cell, spermatid acrosome, and spermatozoa, which has led to the ability of histamine synthesised in spermatozoa through in vitro acrosome reaction. There were significant studies reported on the negative effects upon histamine 1 (H1R) and histamine 2 (H2R) receptors antagonist administration on sperm parameters such as sperm count, motility, and sperm viability, herein speculates that H1R and H2R may be present on sperm. Therefore, this study aimed to detect H1R and H2R on murine sperm by cellular and molecular studies. The H1R and H2R localization on murine sperm was detected by immunocytochemistry technique. The sperm was smeared onto poly-lysine coated slide and allowed to dry prior to fixation and permeabilisation processes. The primary antibody encoded for receptors was exposed to fluorescently tagged antibody; fluorescein isothiocyanate (FITC) conjugate followed by nuclear staining with 4’, 6-diamino-2-phenylindole dihydrochloride (DAPI). The testis, stomach, and skin of mice were used as the positive control tissues, underwent the same procedures as sperm to verify the immunocytochemical evidence. In molecular study, sperm RNA was extracted by TRIzol method and reverse transcribed for complementary DNA (cDNA) synthesis prior to Polymerase Chain Reaction (PCR) for amplification of H1R and H2R genes which subsequently to detect the presence of the receptors molecularly. The purified DNA underwent DNA sequencing as a final verification step of study. Result showed that H1R and H2R were present on the midpiece and acrosome of epididymal sperm in cellular study and the presence of both receptors was supported by molecular evidence. The presence and immunolocalisation of H1R and H2R on the midpiece and acrosome coincide with the mapping of corresponding G-proteins on similar locations on mature sperm. The H1R-Gαq/11 and H2R-Gαs coupling initiate the signalling cascades through phospholipase C and adenylyl cyclase, respectively. Therefore, present study proposes that these receptors would be involved in calcium regulatory mechanism and protein phosphorylation which are responsible for fertilisation-related processes
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
