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
Smear layer removal and canal cleanliness using different irrigation systems
No full textThe percentage of failures and the will to establish more practical protocols specifically in the field of endodontics have led, over the years, to the continuous development of new techniques to be able to make more predictable all types of endodontic treatment. Advances in this area are the result of a long process that began in the seventeenth century and that still goes on. The purpose of endodontic treatment is now clearly established, but it changes the path that allows dentists to achieve certain goals. The need to resort to an intervention of endodontic therapy is motivated by the presence of pulpal disease, the cause of which is to be found in bacterial growth within the
endodontic complex. The three basic stages of endodontic treatment are represented by a diagnostic phase, a preparatory phase, during which, through the cleansing and shaping of the canal, removing the root canal content, the disinfection of the endodontic complex is performed
and it is given to the same canal a three-dimensional shape adapted to receive a filling, and finally the obturation phase, during which the canal is clogged with an inert material, capable of ensuring a complete seal of the endodontic complex. Although it is impossible to determine which of the three stages is the most decisive, it is obvious that great importance should be attributed to the cleansing, disinfection and shaping. There is talk of cleansing and shaping because when a root canal system is prepared it is actually cleaned from all organic and inorganic debris, and from all microorganisms, and it is shaped to give a form which facilitates the execution of a correct three-dimensional obturation. The purpose of the cleansing is to remove from the inside of the root canal system the
intracanal material, be it of pulpal origin or micro-organisms. The first phase of the endodontic therapy is the correct opening of the pulp chamber that allows a correct access to all the channels present inside the endodontic complex. The second objective of the first stage of endodontic therapy is the survey of the channels and their morpho-structural anatomical analysis. It then begins a phase of shaping and cleaning of the endodontic complex act to remove the organic and inorganic materials that may prevent proper decontamination and cleansing endodontic. Regardless of the shaping technique and the tools used to perform it, it is of fundamental importance to use
the root canal irrigant. It 'also shown that there are two important conditions to ensure that the cleansing has maximum effectiveness, ie its residence time inside the endodontic complex and its activation. Different agitation and delivering techniques were suggested. Passive ultrasonic irrigation (PUI), firstly described by Weller et al, uses a stainless steel file to activate the irrigant in the canal. PUI is able to disrupt the endodontic biofilm, facilitating better penetration of irrigants throughout the endodontic dentinal walls. The EndoActivator System (EA) (Dentsply Tulsa Dental Specialties, Tulsa, OK) is a sonically driven irrigant activation system designed to produce vigorous intracanal fluid agitation that has been shown to increase the efficacy of irrigation better than traditional needle irrigation (18). The EndoVac System (EV) (Discus Dental, Culver City, CA) is an apical
negative pressure irrigation device designed to drain irrigating solution at the apical third level of the canal system and to remove debris via a negative pressure mechanism. Lasers were introdued as an alternative to irrigant activating methods, able to clean and disinfect root canals. Different lasers at different wavelengths were investigated in an attempt to develop improved treatment methods. Laser activated irrigation (LAI) with erbium lasers was studied as a method to activate irrigating solutions. The aim of my PhD was based on the evaluation of smear layer removal and endodontic wall cleanliness after different irrigant activation regimens, studying and analyzing one by one its materials, techniques and results

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.
