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
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
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
a computed tomography study
No full textHintergrund: Die klinischen Ergebnisse nach künstlichem Hüftgelenksersatz
Implantation von Hüftendoprothesen sind wesentlich von der Rekonstruktion der
Gelenksgeometrie und hier im Speziellen des femoralen Offsets sowie der
postoperativen Funktion der pelvitrochantären Muskulatur abhängig. Anhand der
verfügbaren Literatur ist es jedoch nicht möglich patientenspezifische Ziele
für die Rekonstruktion des femoralen Offsets zu formulieren bzw. postoperativ
auftretende Symptome anhand stabiler Referenzwerte zu analysieren. Bekannt ist
auch, dass bestimmte Patientengruppen (Frauen, Patientenalter > 70 Jahre, BMI
> 25) von der Wahl eines bestimmten Hüftzuganges zur H-TEP-Implantation mehr
profitieren als andere. Welcher Zugang für welchen Patienten jedoch
hinsichtlich der postoperativen Funktion der beste ist, kann anhand der
derzeitigen Datenlage nicht argumentiert werden. Ziel dieser Arbeit ist eine
geschlechtsspezifische, quantitative Analyse des femoralen Offsets und der
pelvitrochantären Muskulatur an Patienten ohne beschriebene
Hüftgelenkspathologie. Die Ergebnisse einer solchen Untersuchung können
zukünftig als Referenzwerte für die Gelenksrekonstruktion sowie als rationale
Basis für die patientenspezifischen Hüftzugangswahl dienen. Methoden:
Datensätze computertomographischer Untersuchungen des Beckens sowie des
proximalen Oberschenkels von 100 bzw. 93 Patienten wurden hinsichtlich des
femoralen Offsets bzw. der Muskelvolumina der pelvitrochantären Muskulatur
(Mm. glutei medius, Mm. glutei maximus, Mm. tensor fasciae latae) analysiert.
Weiter wurden mögliche Geschlechts- und/oder Altersabhängigkeiten sowie
Korrelationen dieser erhobenen Größen mit der Körpergröße und dem
Körpergewicht untersucht. Das Verhältnis der Muskelvolumina der Mm. Gluteus
medius, Mm. Gluteus maximus und Mm. Tensor fasciae latae zueinander wurde
weiter in Abhängigkeit des Geschlechts und des Alters untersucht. Ergebnisse:
Die Vermessung des femoralen Offsets ergab signifikant größere Werte für
Männer (43,6 ± 5,6 mm) als für Frauen (39,5 ± 3,5 mm); in beiden Gruppen
zeigte sich kein Seitenunterschied. Für Männer konnte eine signifikante
Korrelation des femoralen Offsets mit der Körpergröße gefunden werden. Die
gemessenen Muskelvolumina ergaben ebenfalls größere Werte für Männer als für
Frauen für alle einzeln untersuchten Muskelvolumina sowie das Gesamtvolumen
der pelvitrochantären Muskulatur. Sowohl bei Männern als auch bei Frauen
konnten signifikante Korrelationen zwischen den Körpermaßen und den
Muskelvolumina gefunden werden. Männer zeigten mit steigendem Körpergewicht
einen signifikant steileren Anstieg der Muskelvolumina als dies bei Frauen
beobachtet wurde. Die relative Verteilung der Muskelvolumina von Mm. Gluteus
medius, Mm. Gluteus maximus und Mm. Tensor fasciae latae zueinander zeigte
keine Unterschiede in Abhängigkeit des Geschlechts oder des Alters.
Schlussfolgerungen: Die für das femorale Offset gefundenen Referenzwerte
können für eine geschlechtsspezifische Planung und Analyse der
Hüftgelenksrekonstruktion verwendet werden. Die relative Verteilung der
Muskelvolumina der pelvitrochantären Muskulatur kann geschlechts- und
altersspezifische Unterschiede in den Ergebnissen nach Implantation einer
Hüft- TEP nicht erklären. Die größere gewichtsnormalisierte Muskelmasse bei
Männern könnte jedoch eine Erklärung für die besseren postoperativen
Ergebnisse darstellen. Weiter stellen die Ergebnisse dieser Untersuchung die
rationale Grundlage zur geschlechtsspezifischen Planung und Durchführung
klinischer Studien zu Therapieverfahren dar, bei denen die pelvitrochantäre
Muskulatur eine wesentliche Rolle spielt.Background: Clinical results after Total Hip Arthroplasty (THA) are highly
dependent on the reconstruction of joint geometry as well on the amount of
functionally intact pelvitrochanteric muscle mass. Based on the current
literature it is not possible to define goals for individual joint
reconstruction or to analyse postoperative symptoms patient-specifically.
Further it is known that specific patient groups profit more from a certain
surgical approach the others do (women, patients aged over 75a). Which
approach should be used for which patient, however, cannot be argumented based
on the current literature. The aim of this work was to patient-specifically
investigate femoral offset (FO) without osteoarthritis and to provide index
values for reconstruction. Further, the muscle distribution around the hip
joint should be investigated with regard to sex and age. The total muscle
volume and their distribution will be correlated to gender and age. Methods:
100, respectively 93 computed tomography (CT) scans of the pelvis were
analysed. FO was analyzed three dimensionally (n=100). Bi-lateral symmetry and
correlation between demographic data and FO were analyzed. Further, the
volumes of the muscles gluteus medius (GMV), gluteus maximus (GXV) and tensor
faciae latae (TFL) were measured on both sides of the pelvis (n=93). The
distribution of muscle volumes was normalised to the patients’ weight and then
correlated with their sex and age. Results: FO is larger in males (43,6 ± 5,6
mm) than in females (39,5 ± 3,5 mm). No side differences for FO were found.
Significant correlation between height and FO was only observed in males. The
measured muscle volumes featured no major differences between the left and the
right side. The absolute total volume of the hip-encompassing muscular system
(TMV) is bigger in men than in women. Correlations between TMV and the
collected data were observed in both sexes in relation to body weight and body
size. With increased body weight, the TMV of the male patients increased
progressively. The relative distribution of each muscle volume (GMV, GMX, TFL)
around the hip joint showed no major differences with respect to sex and/or
age. Conclusion: These reference values can be used for the restoration and
the evaluation of hip geometry. The equal relative muscle distribution in men
and women around the hip joint reflect neither the sex-related differences
observed in clinical outcomes after THA nor the bony anatomy. Yet men
exhibited more muscle reserves (muscle volume – absolute and in relation to
body mass), which could explain the better outcome of men after THA.
Furthermore, this suggests the extraordinary importance of muscle sparing
surgical approaches in women. The results represent the rationale for the
design and the analysis of future studies of sex-specific therapies with
regard to the hip joint muscles

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.
