Aus Zwei mach Eins: SB XVIII 13997 und P.Vindob. G 21154. Ein arsinoitischer Teilpachtvertrag über Weinland
No full textVereinigte (Neu)Edition eines arsinoitischen Teilpachtvertrages aus dem frühen 7. Jh. Phanamun, Sohn des Menas aus Turubestis erhält einen Teil der Weinernte, drei Teile verbleiben beim Verpächter, dem Schreiber Andreas aus Arsinoe. Zu dem bereits publizierten Ende der Urkunde (SB XVIII 13997) konnte ein weiterer Teil hinzugefunden werden (P.Vindob. G 21154); der Beginn und ein kleiner Teil in der Mitte fehlen weiterhin. Beide Fragmente stammen aus der Wiener Papyrussammlung.Combined (re)edition of an Arsinoite crop share lease from the early 7th century. Phanamoun, son of Menas receives one share of the vintage, while the landlord Andreas, a scribe from Arsinoe keeps the other three shares. The end of the deed is published (SB XVIII 13997) and could be joined with a middle fragment. The beginning and a small middle part remain missing. Both fragments come from the Viennese papyrus collection
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Development of tumors in the liver and metastatic nodules in the lungs of Lkb1 (+/−) and Lkb1 (+/−) mtND6<sup>13997</sup> mice.
No full text<p>Gross necropsy (left) and histological sections (right) of livers (A) and lungs (B). White arrowheads indicate hepatocellular carcinomas in the liver (A) and metastatic nodules in the lung (B). Black arrowheads on the liver sections (A) indicate the borders between the developed tumors (T) and the normal tissues (N). The frequencies of hepatocellular carcinoma formation in Lkb1 (+/−) and Lkb1 (+/−) mtND6<sup>13997</sup> mice were 73.7% (14/19) and 81.3% (13/16), respectively. The frequencies of lung metastasis in Lkb1 (+/−) and Lkb1 (+/−) mtND6<sup>13997</sup> mice were 14.3% (2/14) and 15.4% (2/13), respectively.

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
