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
Alters- und geschlechtsspezifische Unterschiede in Bezug auf Therapie und Outcome bei Beckenringfrakturen
Full text linkHintergrund: Frakturen des Beckens sind seltene, jedoch schwerwiegende Verletzungen. Bei jungen Patienten entstehen diese in aller Regel im Rahmen von hochenergetischen Traumata und sind in einer Vielzahl mit weiteren schweren Verletzungen vergesellschaftet. Durch fortwährende Anstrengungen in der Verkehrssicherheit und Unfallverhütung ist die Anzahl und Letalität von schweren Unfällen über die letzten Jahre gesunken. Auch die Verletzungsmuster und das Outcome nach Beckenverletzungen haben sich hierbei stark verändert. Ziel der vorliegenden Dissertation ist es, Zusammenhänge zwischen Alter (<60 Jahren), Geschlecht, Therapie, Frakturentität und Krankenhausverweildauer hinsichtlich des Outcome (Überleben) bei Beckenringfrakturen über die letzten 22 Jahre zu erfassen.
Material, Patienten und Methodik: Hierzu wurden die Daten aus dem Beckenregister der „Arbeitsgemeinschaft Becken der Deutschen Gesellschaft für Unfallchirurgie (DGU)“ analysiert. Die erfassten Daten wurden prospektiv und multizentrisch über einen Zeitraum von 22 Jahren erhoben. Der Gesamtzeitraum wurde in vier Untergruppen unterteilt, wobei die Zeitgruppe t1 den Zeitraum von 1991-1993, die Zeitgruppe t2 1997-2000, die Zeitgruppe t3 2001-2008 und die Zeitgruppe t4 den Zeitraum 2009-2013 umfassen.
Es wurden 4755 Patientendaten erfasst und analysiert. Eingeschlossen wurden Patienten <60 Jahren mit einer Beckenringfraktur ohne gleichzeitige Acetabulumfraktur, die im Beckenregister der DGU im Zeitraum von 1991 bis 2013 eingeschlossen wurden.
Ergebnisse: Über den Beobachtungszeitraum ließ sich eine signifikante Abnahme der relativen Anzahl von Typ A-Frakturen von 41,7% auf 29,9% beobachten, während die relative Anzahl von Typ B-Frakturen (von 31,5% auf 39,9%) und von Typ C-Frakturen (von 26,7% auf 30,2%) anstieg. Die durchschnittliche Mortalität nahm von 7,7% auf 4,3% ab, während der mediane Injury Severity Score (ISS) von 13 auf zeitweise 18 (in t3) anstieg.
Das Verhältnis zwischen Männern und Frauen betrug ca. 60% zu 40% und blieb über den Beobachtungszeitraum konstant. Während das Geschlecht, der Frakturtyp, die Krankenhausverweildauer und die Wahl der Therapieform (operativ vs. konservativ) einen signifikanten Einfluss auf das Outcome zeigten, zeigte sich kein signifikanter Zusammenhang zwischen Alter (0-60) und Outcome.
Schlussfolgerung: Die Mortalität von Patienten nach Beckenringfrakturen ist über die letzten 22 Jahre signifikant gesunken, während die relative Anzahl an B- und C-Frakturen zugenommen hat. Es besteht ein signifikanter Zusammenhang zwischen Frakturgrad und Mortalität, Geschlecht und Mortalität, Therapieverfahren und Mortalität sowie Krankenhausverweildauer und Mortalität. Es besteht kein signifikanter Zusammenhang zwischen Alter und Mortalität. Über den beobachteten Zeitraum von 22 Jahren stellten wir eine Gender Bias zu Ungunsten des weiblichen Geschlechtes fest.Background: Pelvic ring fractures are rare but severe injuries. In younger patients they typically occur due to high energy traumata and are associated with other severe injuries example given a polytrauma. Due to an improvement in traffic safety and accident prevention, the number of severe traumata and death decreased during the last years. In addition the injury pattern and outcome of pelvic ring fractures has substantially changed. The aim of the following thesis is to analyze the correlation between age (<60), sex, therapy, type of pelvic ring fracture and duration of hospital stay with regard to outcome (survival) of pelvic ring fractures in the period from 1991 to 2013.
Material, Patients and Methods: Hence we retrospectively analyzed the data of the „German Pelvic Trauma Registry“ of the „Arbeitsgemeinschaft Becken der Deutschen Gesellschaft für Unfallchirurgie (DGU)“.
The data was collected prospectively and multicentric over a period of 22 years. The observation period was separated in four subgroups according to changes in the registry. Subgroup t1 ranged from 1991-1993, subgroup t2 reached from 1997-2000, subgroup t3 covered the years 2001-2008 and subgroup t4 ranged from 2009-2013.
Results: The data of 4755 patients was collected and analyzed. We included patients aged <60 with a pelvic ring fracture who were registered in the „German Pelvic Trauma Registry“ of the „DGU“ from 1991 to 2013. Patients with a concomittant fracture of the acetabulum were excluded.
During the observation period we found a significant decrease in the proportion of type A pelvic ring fractures from 41,7% to 29,9% while the proportion of type B (from 31,5% to 39,9%) and C (from 26,7% to 30,2%) fractures increased during the observation period. The mortality decreased from 7,7% to 4,3% while the mean Injury Severity Score (ISS) increased from 13 to 18 (in subgroup t3).
The ratio between male and female was 60% to 40% in all subgroups.
While sex, type of fracture, length of hospital stay and therapy (operative vs conservative) was clearly related to the outcome, there was no relation between age (0-60) and outcome.
Conclusion: The mortality of patients after pelvic ring fractures decreased significantly within the last 22 years, while the relative numbers of type B- and C-fractures increased. There is a significant correlation between type of pelvic ring fracture and mortality, sex and mortality, therapy and mortality and duration of hosptal stay and mortality. There is no significant correlation between age and mortality. Within the last 22 years we recorded a gender bias against the female gender
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

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.
