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
Sprachröhren des Zeitgeistes
No full textFriedrich Schillers Wallenstein-Trilogie und das Demetrius-Fragment werden in dieser Arbeit in ihrer Rolle als Verhandlungsräume des zeitgenössischen Herrschaftsdiskurses um 1800 untersucht. Auf eine Fixierung auf die historische Figur Napoleons wird dabei absichtlich verzichtet, um somit den Blick auf das gesamte diskursive Feld um 1800 zu erweitern. Gleichzeitig wird versucht, die wichtigsten Themen des politischen Diskurses um 1800 zu skizzieren, wobei das Phänomen Masse als das Herzstück der politischen Debatte ausgemacht wird, von dem sich die anderen, hier behandelten Themengebiete entspinnen. Im ersten Abschnitt wird auf Schillers Auseinandersetzung mit der Sprache und mit den Kollektivsymbolen der Französischen Revolution im Wallenstein eingegangen. Weiters werden die Ideologie der Französischen Revolution, der revolutionäre Freiheitsbegriff und das Thema der Interdependenz moderner Macht sowie deren Verhandlung im Wallenstein und im Demetrius analysiert. Im zweiten Abschnitt werden die moderne Diktatur, der Republikbegriff und der Führerkult, die in beiden Dramen behandelt werden, unter die Lupe genommen. Dennoch ist Schiller nicht als politischer Schriftsteller, sondern lediglich als politisch hochinteressierter Autor zu verstehen.In this paper the Wallenstein Trilogy and the Demetrius Fragment are considered as a stage for a political debate where the arguments of the late 18th century are mentioned and showcased by Friedrich Schiller. A fixation upon the historical person Napoleon Bonaparte will be deliberately avoided in order to allow comprehensive coverage of the political discourse of Schiller’s time. As the discursive core of this political debate, the phenomenon of the mass marks the centerpiece for all the other political topics which are reflected upon in these two dramas. In the first part the revolutionary “speak” and Schiller’s work with the political metaphors from the late 18th century will be analyzed. Furthermore, the ideology of the revolution, the revolutionary term of freedom, the topic of the new born interdependence of modern power, as well as Schiller’s work with these subjects in both dramas, will be scrutinized. In the second part, I write about modern dictatorship, the republic, the leader-cult and how these topics are intermingled with the stories of Wallenstein and Demetrius. However, this doesn’t mean that Schiller has to be regarded as a political writer, but rather as an author highly interested in political subjects
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

Involvement of Exo1b in DNA damage-induced apoptosis
No full textApoptosis is essential for the maintenance of inherited genomic integrity. During DNA damage-induced apoptosis, mechanisms of cell survival, such as DNA repair are inactivated to allow cell death to proceed. Here, we describe a role for the mammalian DNA repair enzyme Exonuclease 1 (Exo1) in DNA damage-induced apoptosis. Depletion of Exo1 in human fibroblasts, or mouse embryonic fibroblasts led to a delay in DNA damage-induced apoptosis. Furthermore, we show that Exo1 acts upstream of caspase-3, DNA fragmentation and cytochrome c release. In addition, induction of apoptosis with DNA-damaging agents led to cleavage of both isoforms of Exo1. The cleavage of Exo1 was mapped to Asp514, and shown to be mediated by caspase-3. Expression of a caspase-3 cleavage site mutant form of Exo1, Asp514Ala, prevented formation of the previously observed fragment without any affect on the onset of apoptosis. We conclude that Exo1 has a role in the timely induction of apoptosis and that it is subsequently cleaved and degraded during apoptosis, potentially inhibiting DNA damage repair
