Retrograde scientometric analysis of the scientific role of Cystic Fibrosis
No full textDie zystische Fibrose ist eine autosomal-rezessiv vererbbare Erkrankung und
stellt die häufigste Stoffwechselerkrankung der weißen Bevölkerung Europas und
Nordamerikas dar. Sie ist eine komplexe, multisystemische Erkrankung mit
hauptsächlichem Befall des Gastrointestinaltraktes und der Lunge. Durch
kontinuierliche Fortschritte im Krankheitsverständnis, der Therapie und
medizinischen Versorgung ist in den vergangenen 20 Jahren eine höhere
Lebenserwartung und Lebensqualität CF-Erkrankter erzielt worden. Die
vorliegende szientometrische Analyse hat zum Ziel, die Gesamtheit der
Publikationen zum Thema CF aus den vergangenen Jahrzehnten zu bewerten und zu
vergleichen. Zur Datenerhebung wird von der Datenbank des ISI-Web of Science
des Thomson Scientific Institute Gebrauch gemacht. Der Zeitraum der Analysen
erstreckt sich von 1900-2009. Mathematische Algorithmen, Density Equalizing
Map Projections und Netzdiagramme sind zur grafischen Darstellung der
Ergebnisse verwendet worden. Mit den Termini cystic fibrosis AND
mucoviscidosis sind 37.467 Publikationen in dem besagten Zeitraum
identifiziert worden. 95% der Publikationen sind in englischer Sprache
verfasst worden. Mit 14.886 Publikationen sind die USA das Land mit den
meisten Veröffentlichungen, England folgt auf der zweiten Position. Die USA
vereinen die meisten Zitierungen der Artikel und den höchsten h-Index auf
sich. Bei der Analyse der durchschnittlichen Zitationsrate führt Kanada. Die
meisten Forschungseinrichtungen und internationalen Kooperationsarbeiten
fallen auf die USA zurück. Kanada und Großbritannien sind die
Hauptkooperationspartner. In Form von Articles (64%) sind die meisten
Publikationen veröffentlicht worden. Es folgen die Meeting Abstracts (12%) und
Reviews (8%). Die Mikrobiologie, das respiratorische System sowie die
Pharmakologie und Pharmazie sind die Themengebiete, mit denen sich die
Wissenschaftler am meisten beschäftigen. Die Fachzeitschrift Pediatric
Pulmonology hat mit 1.344 Publikationen die meisten Arbeiten zum Thema CF
veröffentlicht. Renommierte Zeitschriften wie The Lancet und The Journal of
Biological Chemistry sind unter den meistpublizierenden Fachzeitschriften auch
vertreten. Der dänische Professor Niels Hoiby kann mit 265 publizierten
Arbeiten zum Thema CF als produktivster Autor identifiziert werden. Die
meisten Zitate und die höchste ZR weist der chinesische Professor für
Molekular- und medizinische Genetik Lap-Chee Tsui auf. Der amerikanische
Professor für Medizin Richard Boucher besitzt den höchsten h-Index. Die
vorliegenden Daten zeigen, dass die Mukoviszidose-Forschung eine wichtige
Rolle in der Medizin des Respirationstraktes einnimmt. Es ist ein
kontinuierlicher Zuwachs der CF-Forschung zu verzeichnen, der einen enormen
Fortschritt bzgl. des Verständnisses dieser Erkrankung in den vergangenen 20
Jahren aufzeigt. Hinsichtlich verschiedener Kategorien, die in dieser Arbeit
untersucht wurden, führen die USA, gefolgt von europäischen Ländern.Cystic Fibrosis is an inheritable autosomal recessive disease and one of the
most frequent metabolism diseases of Europe’s and North America’s white
population. Cystic Fibrosis is a complex, multisystemic disease, which mainly
affects the gastrointestinal tract and the lung. Due to continuous progress in
understanding CF and a subsequent advancement of its therapy and its medical
treatment during the last 20 years today’s patients can benefit from a higher
expectancy of life as well as from an improved quality of life. The aim of the
present analysis was to assess and to compare research output in cystic
fibrosis research over the past decades. A large database analysis was
performed using the ISI-Web of Science sources from Thomson Reuters. The
period of analysis was 1900 to 2009. Mathematical algorithms, system diagrams
and density-equalizing mapping procedures were used to visualize database
searches. A total of 37.467 entries at ISI Web were registered in the above-
named period. 95% of these entries were published in English. A country-
ranking of the total numbers of entries lists the United States in first
position, followed by England. The United States are leading too with regard
to the number of citations and the h-Index. When average citations per item
were analyzed, Canada is leading. The majority of research institutions and
cooperative works has its origins in the USA. Canada and Great Britain are the
main cooperative partner countries. The most common publication type to impart
the knowledge on cystic fibrosis was the article type (64%), followed by the
meeting abstracts (12%) and the reviews (8%). Microbiology, the respiratory
system as well as pharmacology and pharmacy are among the leading subjects
correlated with cystic fibrosis. The journal Pediatric Pulmonology has
published the most articles (1.344) to deal with cystic fibrosis. Renowned
journals as The Lancet or The Journal of Biological Chemistry are among the
most publishing journals. The Danish professor Niels Hoiby is the most
productive author with a total of 265 publications. When the quantity of
citations and the average citations per item of the authors are considered the
Chinese professor of genetics Lap-Chee Tsui holds this position. The American
professor for medicine Richard Boucher reveals to have the highest h-Index.
The present data indicates the prominent role of cystic fibrosis research in
respiratory medicine. Throughout the past 20 years there is a continuous
increase in research activity that reflects an enormous advance in the
knowledge about this disease. Geographically, North America holds the leading
position in many categories and is followed by a number of European countries
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

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.
