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
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
Design and development of calorimetry at SHiP and SND@LHC
Full text linkThis thesis focuses on calorimetry in the context of searches for rare particle interactions at the
SHiP and SND@LHC experiments at CERN.
The SHiP (Search for Hidden Particles) experiment at CERN SPS is going to be the flagship
experiment for investigating low-coupling physics in the O(10 MeV) to a couple of GeV range.
Its calorimeter system will achieve very good particle identification capabilities and be able
to reconstruct the directionality of electromagnetic shower with excellent precision. This will
enable significant background reduction and the ability to reconstruct neutral final states arising
from possible new physics decays. For this, it relies on plastic scintillator bars traversed by
wavelength-shifting fibres and readout by SiPMs on the one hand and high-precision layers on
the other. The physics requirements of the calorimeter have been studied with Monte Carlo
simulations. The plastic scintillator layers’ light yield was optimised both in simulations and
laboratory studies, yielding a design for usage in the final experiment. The readout electronics
must cover a very large dynamic range, four systems were investigated with the KLauS chip
being identified as having potential for usage in the end experiment. Three test beams were lead
using a modular and custom-built prototype of the SHiP electromagnetic calorimeter system.
There, different readout electronics and detector configurations were evaluated. Preliminary
results allow to establish the robustness of the design for energy reconstruction and particle
identification. These studies are in use for the final design of the energy reconstruction and
particle identification.
The SND@LHC (Scattering Neutrino Detector at the Large Hadron Collider) is a running
experiment placed off-axis at the ATLAS interaction point at 7.2 < η < 8.6. The experiment’s
position enhances the charm parentage of final state νe and ντ from decays inside of ATLAS. A
hadronic calorimeter based on scintillator bars readout by SiPMs is used to identify muons and
measure the energy of hadronic final states from interactions in an emulsion target. The perfor-
mance of the hadronic calorimeter has been studied. Its response to hadronic showers as well
as the development and testing of tagging algorithms used for the calorimeter calibration are
presented. In addition, muon deep inelastic scattering and catastrophic muon bremsstrahlung
background studies have been performed in the emulsion detector together with the develop-
ment of electromagnetic calorimetry techniques. These evaluations are currently being used for
searches for νe in the emulsion detector at [email protected] vorliegende Arbeit befasst sich mit Kalorimetrie im Rahmen der Suche nach seltenen
Teilchenwechselwirkungen in den SHiP- und SND@LHC-Experimenten am CERN.
Das geplante SHiP-Experiment (Search for Hidden Particles) am CERN-SPS soll schwach
wechselwirkende Teilchen im Energiebereich zwischen O(10) MeV) und einigen GeV nachweisen.
Das SHiP-Kalorimeter muss über eine sehr gute Teilchenidentifikation verfügen und in der
Lage sein, die Richtung elektromagnetischer Schauer mit hoher Präzision zu rekonstruieren.
Dies ermöglicht eine starke Unterdrückung von Hintergrundprozessen und die Rekonstruktion
neutraler Endzustände aus Zerfällen möglicher neuer Teilchen. Dafür werden Plastikszintil-
latorstreifen eingesetzt, die einerseits von wellenlängenverschiebenden Fasern durchzogen und
mit SiPMs ausgelesen werden und andererseits auf hochpräzise Lagen. Die physikalischen An-
forderungen an das Kalorimeter wurden mit Monte-Carlo-Simulationen untersucht. Die Lich-
tausbeute der Szintillatoren wurde sowohl in Simulationen als auch in Laborstudien optimiert.
Das daraus folgende Design ist für die Verwendung im endgültigen Experiment vorgesehen.
Für die Ausleseelektronik, die einen sehr großen dynamischen Bereich abdecken muss, wurden
vier verschiedene Systeme untersucht. Der von der Universität Heidelberg stammende ASIC
KLauS wurde dabei als geeignet für den Einsatz im endgültigen Experiment identifiziert. Drei
Teststrahlkampagnen wurden mit einem speziell entwickelten, modularen Prototypen des elek-
tromagnetischen SHiP-Kalorimeters durchgeführt. Dabei wurden verschiedene Detektorkonfig-
urationen und Datenauslesesysteme getestet. Die Ergebnisse belegen die Eignung des Designs
für die Energierekonstruktion und Teilchenidentifikation.
Das zur Zeit laufende SND@LHC-Experiment (Scattering and Neutrino Detector at the
Large Hadron Collider) befindet sich nahe des ATLAS-Wechselwirkungspunkts im Bereich
7.2 < η < 8.6 außerhalb der LHC-Strahlachse. Durch die Position des Experiments stammt
ein großer Anteil an νe- und ντ -Neutrinos aus Charmproduktion bei ATLAS. Ein hadronisches
Kalorimeter, basierend auf Szintillatorstreifen mit SiPM-Auslese, wird verwendet, um Myonen
zu identifizieren und die Energie hadronischer Endzustände zu messen. Die Leistungsfähigkeit
des hadronischen Kalorimeters wurde eingehend untersucht. Sowohl der Nachweis von hadronis-
chen Schauern als auch die Entwicklung und der Test von Softwarealgorithmen zum Tagging, das
für die Kalibrierung des Kalorimeters verwendet wird, werden vorgestellt. Zusätzlich wurden
Studien zu tief-inelastischer Myonstreuung und katastrophaler Myon-Bremsstrahlung im Emul-
sionsdetektor durchgeführt, ebenso wie zur Rekonstruktion von elektromagnetischen Schauern.
Die Ergebnisse werden derzeit zur Suche nach νe-Neutrinos im SND@LHC-Emulsionsdetektor
genutzt.259 Seiten ; Illustrationen, Diagramm

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.
