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

Establishing stable cell lines for the generation of interaction profiles of proteins involved in RNA editing
No full textAdenosin zu Inosin Editierung von Ribonukleinsäuren (RNA) ist eine konservierte post-transkriptionelle Modifikation in höheren Metazoen. Die hydrolytische Desaminierung von Adenosin zu Inosin wird von einer Enzymfamilie durchgeführt, welche als Adenosin-Deaminasen bekannt sind (ADARs) und doppelsträngige RNA desaminieren. Durch RNA-Editierung wird die Sequenz eines primären Transkriptes verändert, was dramatische Auswirkungen haben kann: Editierung der mRNA eines kodierenden Transkriptes kann zu alternativem Splicing und Aminosäurensubstitutionen im translatierten Protein führen. Abgesehen davon gehören nicht-codierende RNAs und repetitive Sequenzen, wie Alu-Elemente und micro RNAs, zu den Hauptsubstraten von ADARs. Editierung dieser Substrate kann Einfluss auf die Expression von Genen haben, weil die Sequenz regulatorischer Elemente und kleiner RNAs verändert wird. Durch aktuelle Studien wurden bereits viele Substrate für ADAR-vermittelte Editierung identifiziert. Jedoch sind Auswirkungen der Editierung auf die Funktion vieler prozessierter Substrate noch nicht bekannt. Zusätzlich zu den unbekannten Konsequenzen der RNA-Editierung gibt auch die Regulation dieses Mechanismus Rätsel auf.
In den vergangenen Jahren wurden in unserer Arbeitsgruppe einige Kandidaten identifiziert, welche als mögliche Regulatoren für RNA-Editierung in Frage kommen. In diesem Projekt haben wir versucht, diese Kandidaten stabil in Säugerzellen zu exprimieren, um durch Aufreinigungsmethoden und anschließende massenspektrometrische Analyse Interaktionsnetzwerke dieser Kandidaten aufzuklären. Der zweite Teil dieser Arbeit behandelt zwei Substrate für RNA-Editierung: das zytoskelettale Protein Filamin A und BLCAP, ein Protein, assoziiert mit der Entstehung von Blasenkrebs. Editierte und nicht editierte Versionen dieser Proteine wurden stabil in Säugerzellen exprimiert. Durch Aufreinigungsexperimente unter nativen Bedingungen und anschließender massenspektrometrischer Analyse konnten einige Proteine identifiziert werden, welche mit diesen ADAR-Substraten interagieren.Adenosine to inosine RNA editing is a posttranscriptional modification highly conserved in higher metazoa. The hydrolytic deamination of adenosine to inosine is catalysed by a family of enzymes, known as adenosine deaminases that act on double-stranded RNA (ADARs). Changing the sequence of a primary transcript by RNA editing can have dramatic consequences: Editing of the pre-mRNA of a coding transcript can lead to alternative splicing events and may cause amino acid substitutions in the translated protein, as the triplet codon becomes changed. Apart from that, most of the known substrates of RNA editing are non-coding RNAs and repetitive elements, as Alu elements in untranslated regions of the transcript, and micro RNAs. These editing events can influence gene expression, as the sequence of regulatory elements or the target specificity of small RNAs is altered. To date, on-going studies have identified many targets of ADAR editing. However, very little is known about the consequences of the editing events. In addition to the consequences of editing on its targets, mechanisms of regulation of A to I editing are still unclear.
In the last few years several candidates for regulators of ADAR activity have been identified in our lab. In this thesis we stably expressed these candidates in mammalian cell lines for purification assays. Subsequent mass spectrometric analysis of purified complexes led to the identification of proteins interacting with editing regulator candidates, what may help to clarify regulatory networks involved in A to I RNA editing. The second part of this project deals with two protein-coding targets of RNA editing: The effect of RNA editing on the interaction profiles of the cytoskeletal cross-linker Filamin A, and the bladder cancer associated protein BLCAP is investigated. Edited and unedited versions of both proteins were stably expressed in mammalian cell lines. Purification of the two targets of RNA editing under native conditions led to the identification of interacting proteins after mass spectrometric analysis
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.
