At the Decisive Point in the Sinai
No full textThe Yom Kippur War, also known as the Ramadan War or the October War, was fought by Israel against a coalition of Arab nations, led by Syria and Egypt. The war lasted nineteen days, with the pivotal moment being Major General Ariel Sharon’s crossing of the Suez Canal, which is known as the crossing battle In this narrative Jacob Even and Simcha B. Maoz consider the war and Sharon’s leadership as a case study of generalship for the benefit of new generations of senior field commanders. By focusing on the divisional command, Even and Maoz balance the macro view of the war (in the context of the political atmosphere of the time) with the micro view (as a cascade of individual decisions made by each commanding officer).</p
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
On the Defensive, October 10–14
No full textEven and Maoz divide the Southern Command’s six-day defensive period into three sections. October 9 was a pseudodefensive during which the 143rd Division saw great violence. October 10–13 was a time of restive dormancy, and October 14 brought a role change and a reversal of fortune to the IDF. Physically, this period of the war featured low-intensity combat interspersed with furious fire at key points, while diplomatically, drama roiled, future moves were planned, and crucial issues were decided. During the division’s four days of dormancy, Sharon reorganized his brigades, absorbed reinforcements, repaired equipment, and formulated operational plans for the eventual canal crossing.</p
The Crossing Battle, Part 2
No full textThe 143rd Division had two primary tasks to accomplish during the crossing battle on the night of October 15–16: to open and secure the Akavish and Tirtur Roads to access the bridgehead, and to bring their division, as well as the 162nd Division and other forces, to the western side of the canal in preparation for Operation Stouthearted Men. The second task was assigned to the 247th Brigade, which would begin by securing a bridgehead on the other side of the canal. Then the 421st Brigade would deploy the crossing equipment and the bridging battalions would construct and maintain bridges over the canal. This task was the linchpin of the division’s entire mission—the success of Operation Stouthearted Men and the crossing battle depended on the 247th Brigade’s ability to capture, secure, and defend the bridgehead.</p
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
