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
Il laser a diodi in chirurgia orale
No full textLe finalità e gli scopi di ogni procedura chirurgica sono quelli di poter eliminare la lesione definita patologica, comportando minori danni possibili ai tessuti limitrofi e creando le premesse affinché si abbia localmente un processo di guarigione senza complicanze a breve, medio e lungo termine.
Questi principi sono validi anche nel vasto campo delle applicazioni dei raggi laser.
Il mercato propone numerose apparecchiature laser, che presentano particolari specificità insite alle caratteristiche delle onde elettromagnetiche prodotte.
Queste particolari specificità non sono solo messe in relazione alle caratteristiche del taglio dei tessuti, ai tempi di lavoro, alla profondità delle ferite chirurgiche o alle metodiche di esecuzione, ma sono rivolte alla specificità di assorbimento delle onde laser di ogni singola componente tissutale.
Il laser a diodi in particolare si rivela efficace per alcune caratteristiche fondamentali:
• completa sterilità della fonte energetica con conseguente decontaminazione e sterilizzazione dei tessuti trattati;
• minor aumento della temperatura sul bersaglio trattato in confronto ai parametri simili di trattamento con altri tipi di laser;
• minima necessità di utilizzazione dell’anestetico locale;
• perfetto controllo dell’emostasi, dovuto all’ottima affinità verso l’emoglobina, che lo rendono adatto a qualsiasi intervento di piccola chirurgia orale;
• minima indispensabilità dell’applicazione di punti di sutura;
• minimo danno al tessuto circostante l’area di trattamento.
Si può considerare quindi il laser non solo un dispositivo tecnologicamente avanzato che permette di trattare chirurgicamente lesioni organiche con grande facilità, ma una metodica terapeutica selettiva che consente di identificare componenti organici e tissutali da poter colpire con assoluta precisione.The finality and scope of each surgery procedure is the capacity to delete the wound , defined as pathological , providing less eventual damages to neighbouring tissues and creating the conditions for a local recovery process in short medium and long term.
Those statements are valid also in the wide field of laser rays’ applications.
The market offers many kind of laser equipments which are provided with specific particularities highlighted in the electromagnetic waves features.
These peculiarities are connected not only to the tissue’s cut characteristics, to the working time and to the wounds deepness or to the execution modalities.
They are oriented towards the absorption potentials of the laser waves in each tissue’s component.
In particular diode lasers are particularly effective for some fundamental features:
• complete sterility of the power source with a consequent decontamination and sterilization of the treated tissues;
• less temperature increasing on the mark compared to similar treatments with other kind of lasers;
• minimal need of local anaesthetic;
• perfect control on haemostasis owed to the optimal affinity with the haemoglobin that see it fit to any surgical oral intervention;
• minimal need of stitches;
• minimal damage of neighbouring tissues.
Therefore we can consider the diode laser not only an high tech device that allow to treat organic wounds with ease, but a selective therapeutic method that permit to identify organic components and tissues to treat with absolute accuracy

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.
