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
Probabilistische analyses van aanbestedingsonzekerheden
No full textDe aanleiding voor dit afstudeerwerk was de constatering van Holland Railconsult dat hun begrotingen vaak lager waren dan het laagste bod bij een aanbesteding en dat zij vermoedden dat er een grotere marge rondom de begroting benodigd is om met een bepaalde betrouwbaarheid het laagste bod te vangen dan men in eerste instantie dacht. Men wilde graag weten of dit bij andere ingenieursbureaus eveneens het geval is. Tevens was men geïnteresseerd in de scherpte en nauwkeurigheid van de eigen begrotingen en die van concurrerende ingenieursbureaus. Enerzijds beweren aannemers vaak dat zij beter kunnen calculeren dan een ingenieursbureau. Zij hebben de uitvoeringservaring en moeten het werk ook echt maken voor de prijs die zij indienen. Anderzijds menen ingenieursbureaus dat zij juist nauwkeuriger kunnen calculeren omdat ze het ontwerp, dat zij zelf hebben gemaakt, beter kennen. De uiteindelijke begroting van de opdrachtgever en de bieding van een aannemer bestaan uit de kostprijs plus onder andere de winst. Welk winstpercentage een aannemer in rekening brengt is voor een opdrachtgever echter vaak moeilijk in te schatien. Dit is onder meer afhankelijk van de marktsituatie, maar ook van de situatie binnen het bedrijf zelf. In dit rapport zijn de scherpte en nauwkeurigheid van begrotingen van Holland Railconsult, DHV en de Bouwdienst van Rijkswaterstaat bepaald. Tevens is met behulp van modellen nagegaan wat de invloed is geweest van vooroverleg op de biedingen van de aannemers. Ook is onderzocht of een second opinion bij de bepaling van de begroting voor een hogere nauwkeurigheid kan zorgen. De nauwkeurigheid en de scherpte van begrotingen. Voordat verder wordt ingegaan op de scherpte en de nauwkeurigheid van de begroting wordt eerst toegelicht wat hieronder wordt verstaan. Scherpte is een relatief begrip, indien een begroting lager is dan een bieding, dan is de begroting scherper dan dat bod en het bod minder scherp dan de begroting. In dit rapport is de scherpte van de begrotingen van de drie bedrijven onderzocht ten opzichte van het gemiddelde bod bij een aanbesteding. Onder nauwkeurigheid wordt de variatiecoHficient rondom de betreffende begroting (of bieding) verstaan. Hoe kleiner deze is, des te nauwkeuriger de begroting (of bieding) is. De nauwkeurigheid en scherpte van de begroting bleken voor de ter beschikking gestelde projecten per ingenieursbureau behoorlijk te verschillen. De nauwkeurigheid van de begrotingen van Holland Railconsult, DHV en Rijkswaterstaat waren vóór Zembla (de televisie-uitzending van 9 november 2001 waarin dhr. Bos zijn onthulling deed) respectievelijk 11 %, 10 % en 21 % terwijl de variatiecoHficient van de biedingen 5 % was. De reden voor het grote verschil tussen de variatiecoHficient van de biedingen voor Zembla en de variatiecoëfficient van de begroting van de ingenieursbureaus is vermoedelijk het bij laten zakken van de biedingen door de aannemers. Het grote verschil in variatiecoHficient tussen Rijkswaterstaat enerzijds en Holland Railconsult en DHV anderzijds wordt mogelijk veroorzaakt door het feit dat Rijkswaterstaat de marktsituatie niet meeneemt in de begroting. DHV en Holland Railconsult doen dit namelijk meestal wel. Ook de scherpte van de begroting verschilde per bedrijf. Holland Railconsult zat gemiddeld 7 % onder het gemiddelde bod, DHV 12 % daarboven terwijl Rijkswaterstaat er gemiddeld 6 % onder zat.Hydraulic EngineeringCivil Engineering and Geoscience
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.
