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
Steroid receptor expression in human endometrium during the follicular phase of stimulated cycles
No full textThe biological role of endometrium is to provide an environment for the implantation and development of the embryo. In order to achieve this task, endometrium undergoes regular cyclic changes. It is well known, that these changes are regulated by ovarian steroids through their direct action on their endometrial receptors. The low implantation rate following ovarian stimulation has led to the hypothesis that decreased endometrial receptivity might be responsible for the high implantation failure in IVF. Most studies in stimulated cycles focus on luteal phase. Up to date there is limited information available in the literature about the status of endometrial steroid receptors in the follicular phase of patients undergoing stimulation. In 31 patients (age <39 years) stimulated with gonadotrophins and GnRH antagonists for intrauterine insemination (IUI) an endometrialbiopsy was performed on the first day after the end of menstruation and a second biopsy was performed two (Group 0 + 2, n = 10) or four (Group 0 + 4, n = 11) days after the first biopsy, or on the day of hCG administration (Group 0 + hCG, n = 10). Expression of progesterone (PR) and estrogen (ER) receptor was investigated by immunohistochemistry using monoclonal antibodies. The results of the current study shows that PR and ER levels were significantly increased in the second versus the first biopsy, in all groups analyzed (P = 0.01), in both stromal and glandular cells. Between the three groups compared, a significant increase in PR expression was observed for glandular cells (P = 0.03), with the highest value observed in Group 0 + 4. Moreover, the increase in PR expression in stromal cells differed between groups (P = 0.01), with the highest value observed in the Group 0 + hCG. In conclusion, in stimulated cycles for IUI, ER expression in both glandular and stromal endometrial cells, after an initial increase, does not appear to change significantly during the follicular phase. On the contrary, during the same period of time, following an initial rise, PR expression in glandular and stromal cells continues to increase.Ο βιολογικός ρόλος του ενδομητρίου είναι να παρέχει ένα φιλικό περιβάλλον για την εμφύτευση και ανάπτυξη του εμβρύου. Για να επιτευχθεί αυτό, το ενδομήτριο υποβάλλεται σε τακτικές κυκλικές αλλαγές. Είναι γνωστό, ότι οι μεταβολές αυτές ρυθμίζονται από τις στεροειδείς ορμόνες μέσω της άμεσης δράσης τους στους ενδομήτριους υποδοχείς τους. Το χαμηλό ποσοστό εμφύτευσης μετά τη διέγερση των ωοθηκών έχει οδηγήσει στην υπόθεση ότι η μείωση του ενδομήτριας δεκτικότητας μπορεί να ευθύνονται για την υψηλή αποτυχία εμφύτευσης στην εξωσωματική γονιμοποίηση. Οι περισσότερες μελέτες σε κύκλους διέγερσης αφορούν στην ωχρινική φάση. Μέχρι σήμερα υπάρχουν περιορισμένες διαθέσιμες πληροφορίες στη βιβλιογραφία σχετικά με τους ενδομήτριους ορμονικούς υποδοχείς στην ωοθυλακική φάση των ασθενών που υποβάλλονται σε διέγερση. Σε 31 ασθενείς (ηλικίας <39 ετών) οι οποίες δέχθηκαν διέγερση με rec FSH και GnRH ανταγωνιστές για ενδομήτρια σπερματέγχυση υποβλήθηκαν σε ενδομήτρια βιοψία την πρώτη ημέρα μετά το τέλος της εμμήνου ρύσεως και μια δεύτερη βιοψία σε δύο (Ομάδα 0 + 2, n = 10) ή τέσσερις (Ομάδα 0 + 4, n = 11) ημέρες μετά την πρώτη βιοψία, ή την ημέρα της χορήγησης της hCG (Ομάδα 0 + hCG, n = 10). Η Έκφραση των υποδοχέων της προγεστερόνης (PR) και των οιστρογόνων (ER) μελετήθηκε με ανοσοϊστοχημεία χρησιμοποιώντας μονοκλωνικά αντισώματα. Τα αποτελέσματα της τρέχουσας μελέτη δείχνουν ότι τα επίπεδα των ER αυξήθηκαν σημαντικά κατά τη δεύτερη σε σχέση με την πρώτη βιοψία, σε όλες τις ομάδες που αναλύθηκαν (P = 0,01), και στα στρωματικά και στα αδενικά κύτταρα. Μεταξύ των τριών ομάδων, μια σημαντική αύξηση στην έκφραση των PR παρατηρήθηκε για τα αδενικά κύτταρα (P = 0,03), με την υψηλότερη τιμή στην ομάδα 0 + 4. Επιπλέον, η αύξηση στην έκφραση των PR στα στρωματικά κύτταρα διέφερε μεταξύ των ομάδων (P = 0,01), με την υψηλότερη τιμή στην Ομάδα 0 + hCG. Συμπερασματικά, σε κύκλους διέγερσης για ενδομήτρια σπερματέγχυση, η έκφραση των ER στα αδενικά και στρωματικά κύτταρα του ενδομητρίου, μετά από μια αρχική αύξηση, δεν φαίνεται να μεταβάλλονται σημαντικά κατά τη διάρκεια της ωοθυλακικής φάσης. Αντιθέτως, κατά την ίδια χρονική περίοδο, μετά από μια αρχική αύξηση, η έκφραση των PR στα αδενικά και στρωματικά κύτταρα συνεχίζει να αυξάνεται

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
