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
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
Διερεύνηση σχημάτων επιλογής που αξιοποιούν μεθόδους ποσοτικής και μοριακής γενετικής για την βελτίωση της καλλιεργούμενης τσιπούρας (Sparus aurata L.)
No full textIn the present PhD thesis, the available seabream molecular genetic resources were utilized to conduct a partial genome scan for locating possible QTL linked to sex, body weight and eighteen other morphometric characters. For that reason, microsatellite markers were chosen from the existing genetic linkage maps of S. aurata, in order to cover nine linkage groups (LG1, 2, 3, 6, 9, 10, 21, 23 and 25). In total, 74 informative microsatellites were genotyped on 58 brooders and 409 offspring (360 males and 49 females), comprising ten paternal half-sib families. Given the pedigree structure, the QTL detection method was based on half-sib interval mapping analysis through a linear regression approach. The QTL scan was also linked to results retrieved through comparative analysis to other fish species, where candidate regions for sex determination and growth were proposed.Chromosome-wide and genome-wide significant evidence for QTL segregation within the ten chosen paternal half-sib families was found on seven (1, 6, 9, 10, 21, 23 and 25) out of nine examined linkage groups. In total, four QTL affecting body weight and six QTL affecting morphology (using body weight as a covariate) were detected under the assumption of the one-QTL model, while six sex-related QTL were identified under the two-QTL model of analysis (three pairs in three different LGs). Comparison of two-QTL vs. one-QTL model showed that the one-QTL model was of better fit for body weight and morphology QTL while the two-QTL model was of better fit for sex-linked QTL. The proportion of phenotypic variation explained by all the identified QTL herein was medium to high, ranging from 9.3 to 28.7%.Body weight was significantly associated at a genome-wide scale with two QTL positioned on linkage groups 1 and 21 (qBW1 and qBW21, respectively), exhibiting large fractions of phenotypic variance explained (14.8% and 17.2%, correspondingly). Moreover, when fitting body weight as a covariate in the analysis, six QTL affecting morphometric characters were detected. The results herein combined with those from other studies reveal highly significant QTL affecting both morphology and bodyweight in gilthead seabream; this highlights the great potential for the implementation of selective breeding programs (through the combination of Marker Assisted Selection-MAS and classical selection) that focus on improvement of S. aurata overall growth, including size and shape. Finally, the mechanism of S. aurata sex change is thought to be controlled up to date by time (reversal occurs after the second year of life) as well as social and group dynamics. The present thesis, however, provides strong evidence for the existence of genetic control in sex reversal for this teleost fish.Στην παρούσα διδακτορική διατριβή χρησιμοποιήθηκαν κάποια από τα διαθέσιμα μοριακά και γονιδιωματικά «εργαλεία» που υπάρχουν στην τσιπούρα, προκειμένου να διεξαχθεί μία μελέτη ανίχνευσης των QTL που επηρεάζουν το σωματικό βάρος, το φύλο και 18 ακόμη μορφομετρικούς χαρακτήρες, καλύπτοντας ένα μεγάλο μέρος του γονιδιώματος του είδους. Για το λόγο αυτό χρησιμοποιήθηκαν μικροδορυφορικοί δείκτες από τους υπάρχοντες γενετικούς χάρτες σύνδεσης της τσιπούρας ώστε να καλύψουν εννέα ομάδες σύνδεσης (1, 2, 3, 6, 9, 10, 21, 23 και 25). Συνολικά έγινε γονοτύπηση με 74 μικροδορυφόρους σε 58 γονείς και 409 απογόνους (360 αρσενικά και 49 θηλυκά άτομα), οι οποίοι σχημάτιζαν δέκα ετεροθαλείς οικογένειες έχοντας για κοινό γονέα αρσενικό άτομο. Δεδομένης της δομής των οικογενειών, η μέθοδος ανίχνευσης QTL βασίστηκε στην ανάλυση διαστήματος μέσω της γραμμικής παλινδρόμησης. Η μελέτη για τον εντοπισμό QTL βασίστηκε επίσης σε αποτελέσματα συγκριτικής χαρτογράφησης του γονιδιώματος της τσιπούρας με γονιδιώματα άλλων ειδών, για τα οποία έχουν βρεθεί γονιδιακοί τόποι που επηρεάζουν το φύλο και την ανάπτυξη.Στατιστικά σημαντική απόδειξη για την ύπαρξη QTL, στις δέκα υπό μελέτη ετεροθαλείς οικογένειες, βρέθηκε σε εφτά (1, 6, 9, 10, 21, 23 και 25) από τις εννέα ομάδες σύνδεσης που αναλύθηκαν. Συνολικά βρέθηκαν τέσσερα QTL που επηρεάζουν το βάρος, έξι QTL που σχετίζονται με μορφομετρικούς χαρακτήρες (χρησιμοποιώντας το βάρος ως συμμεταβλητή) και τρία ζεύγη QTL που επηρεάζουν το φύλο (σε τρεις διαφορετικές ομάδες σύνδεσης). Το ποσοστό της φαινοτυπικής παραλλακτικότητας που εξηγείται από τα ανιχνευθέντα QTL ήταν μέτριο ως υψηλό, κυμαινόμενο από 9.3 έως 28.7%.Το σωματικό βάρος βρέθηκε να είναι στατιστικώς σημαντικά συνδεδεμένο σε επίπεδο γονιδιώματος με δύο QTL ευρισκόμενα στις ομάδες σύνδεσης 1 και 21 (qBW1 και qBW21, αντίστοιχα). Επιπλέον, όταν χρησιμοποιήθηκε το βάρος ως συμμεταβλητή στην ανάλυση, εντοπίστηκαν έξι QTL που επηρεάζουν μορφομετρικές ιδιότητες. Τα αποτελέσματα της παρούσας διατριβής σε συνδυασμό με αυτά διαφόρων άλλων παρεμφερών επιστημονικών μελετών αποκαλύπτουν την ύπαρξη QTL με στατιστικά σημαντικές τιμές που επηρεάζουν το βάρος και τη μορφολογία στη τσιπούρα. To γεγονός αυτό καταδεικνύει τη μεγάλη δυναμική που υπάρχει για την εφαρμογή προγραμμάτων επιλογής (μέσω του συνδυασμού Marker Assisted Selection–MAS και κλασσικής επιλογής) που θα στοχεύουν στη γενετική βελτίωση του μεγέθους και του σχήματος στην τσιπούρα. Τέλος, ο μηχανισμός αλλαγής του φύλου στην τσιπούρα πιστεύεται μέχρι σήμερα ότι ελέγχεται από παράγοντες κοινωνικής δομής καθώς και παράγοντες δυναμικής πληθυσμών. Παρόλα αυτά, τα αποτελέσματα της παρούσας διατριβής αναδεικνύουν την ύπαρξη γενετικού ελέγχου στην αναστροφή φύλου του συγκεκριμένου είδους

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.
