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
Πρότυπα παραγωγής και ατμοσφαιρικής κυκλοφορίας γυρεοκόκκων στην ευρύτερη περιοχή Θεσσαλονίκης
No full textAirborne pollen grains were sampled in Thessaloniki by use of a Burkard volumetric trap, which operates daily, drawing a constant volume of air. It was found that the most abundant pollen grains belonged to the woody Cupressaceae, Oleaceae, Pinaceae, Quercus and Platanus and to the herbaceous Poaceae and Urticaceae. Pollen circulation extends from February to October, with the main pollen season occurring during March to May. Floral phenology and pollen production of Corylus avellana, Cupressus sempervirens, Olea europaea and Platanus orientalis were also studied during 2004 and 2005, under differing environmental conditions (elevation, exposure or both). Differences were observed in both flowering phenology and pollen production between sampling years but also between stations. It was found that at higher elevations and northern exposures pollen production was lower and flowering started or peaked later. The highest pollen production (per flower) was found in O. europaea, whereas the highest flower production (per inflorescence) was found in P. orientalis. The number of pollen or flowers produced - per floral unit - is mainly regulated by the size of floral units, for all taxa. Moreover, it was found that seasons of flowering phenology and pollen atmospheric circulation may coincide (O. europaea, C. sempervirens), but they could also be unsynchronised, with either earlier flowering (C. avellana) or later flowering (P. orientalis). Pollen atmospheric circulation is mainly related with wind (direction, speed and persistence) and with precipitations. Even the lowest values of the latter washed out airborne pollen. The relationship with wind persistence was always positive, as it frequently was for the interaction of wind speed-persistence. Moreover, it was found that the yearly concentrations of pollen are increasing for the majority of the taxa examined (12 out of 16) but also for the yearly total, during the last two decades. In average, the pollen atmospheric load doubles every decade. Few and non-systematic trends were observed in phenological traits of pollen circulation season (start, peak, end, duration). These increasing trends are accompanied to an increase in air temperature, which is the only meteorological factor (of the 19 examined in total) to present significant changesΣυλλέχθηκαν οι γυρεόκοκκοι στην ατμόσφαιρα της Θεσσαλονίκης με χρήση γυρεοπαγίδας Burkard, η οποία λειτουργεί σε συνεχή βάση, προσροφώντας σταθερό όγκο ατμοσφαιρικού αέρα. Βρέθηκε ότι οι αφθονότεροι γυρεόκοκκοι προέρχονται κυρίως από τα ξυλώδη Cupressaceae, Oleaceae, Pinaceae, Platanus και Quercus και από τα ποώδη Poaceae και Urticaceae. Η κυκλοφορία γυρεοκόκκων εκτείνεται Φεβρουάριο με Οκτώβριο, με την κορύφωσή της να σημειώνεται την περίοδο Μαρτίου-Μαΐου. Μελετήθηκαν επιπλέον η ανθική φαινολογία και η γυρεοπαραγωγή των Corylus avellana, Cupressus sempervirens, Olea europaea και Platanus orientalis κατά τα έτη 2004 και 2005, κάτω από διαφορετικές περιβαλλοντικές συνθήκες (υψόμετρο ή και έκθεση). Παρατηρήθηκαν διαφορές στη φαινολογία άνθησης και στη γυρεοπαραγωγή τόσο μεταξύ σταθμών όσο και μεταξύ ετών δειγματοληψίας. Η γυρεοπαραγωγή ήταν χαμηλότερη και η άνθηση ξεκινούσε ή κορυφωνόταν αργότερα σε βόρειες εκθέσεις ή σε μεγαλύτερα υψόμετρα. Την υψηλότερη γυρεοπαραγωγή (σε επίπεδο άνθους) σημείωσε το O. europaea, ενώ την υψηλότερη ανθοπαραγωγή (σε επίπεδο ταξιανθίας) το P. orientalis. Το μέγεθος της γυρεοπαραγωγής ή και της ανθοπαραγωγής ανά ανθική μονάδα καθορίζεται κυρίως από το μέγεθος των τελευταίων, σε όλα τα taxa. Προέκυψε ακόμη ότι οι εποχές άνθησης και ατμοσφαιρικής κυκλοφορίας γυρεοκόκκων μπορεί να συμβαδίζουν (O. europaea, C. sempervirens), αλλά μπορεί να είναι και ετεροχρονισμένες, με πρωθύστερη άνθηση (C. avellana) ή μεθύστερη άνθηση (P. orientalis). Η ατμοσφαιρική κυκλοφορία γυρεοκόκκων φαίνεται να σχετίζεται κυρίως με τον άνεμο (διεύθυνση, ταχύτητα και εμμονή), καθώς και με τα υδάτινα κατακρημνίσματα. Έστω και ελάχιστη παρουσία των δεύτερων μηδένιζε τις ατμοσφαιρικές συγκεντρώσεις γυρεοκόκκων. Η σχέση με την εμμονή του ανέμου ήταν πάντα θετική, όπως ήταν συνήθως και με την αλληλεπίδραση εμμονής-ταχύτητας. Επίσης, βρέθηκε ότι αυξάνονται οι ετήσιες ατμοσφαιρικές συγκεντρώσεις γυρεοκόκκων για 12 από 16 μελετώμενα taxa, όπως και για το ετήσιο σύνολο, στις τελευταίες δύο δεκαετίες. Κατά μέσο όρο, το ατμοσφαιρικό φορτίο διπλασιάζεται κάθε δεκαετία. Δεν παρατηρήθηκαν συστηματικές μεταβολές στα φαινολογικά χαρακτηριστικά κυκλοφορίας (έναρξη, κορύφωση, λήξη, διάρκεια). Αυτές οι αυξητικές τάσεις συνοδεύονται από αύξηση της θερμοκρασίας του αέρα, που αποτελεί και το μοναδικό μετεωρολογικό παράγοντα (από τους 19 συνολικά που μελετήθηκαν) με συστηματικές και σημαντικές αλλαγές
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

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.
