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
Adaptive control of HPC clusters for server overload avoidance
No full textLAUREA MAGISTRALEQuesta tesi si focalizza nell’usare al meglio le risorse di un High-Performance Computing
(HPC) con un accento sul sovraccarico della memorial esterna.
Gli HPC sono diventati fondamentali nell’ambito scientifico per la loro potenza com-
putazionale che sorpassa ogni limite prescritto dal singolo computer. Data la loro impor-
tanza e potenza, queste strutture vengono ad un costo non ignorabile e, sfortunatamente,
anche ad un ciclo di vita relativamente breve. Di conseguenza, diventa molto importante
sfruttare al meglio tutte le risorse di un HPC durante il suo ciclo vitale. Proprio in
questo contesto nasce l’Autonomic computing che da’ inizio alla cooperazione tra esperti
di informatica e controllo.
Questa Tesi Magistrale è solo una parte di un progetto più ampio. Infatti, nel lavoro
precedente, si è costruito un PI in modo da minimizzare le risorse inutilizzate in un HPC
Cluster. Però, il controllore è stato disegnato su un modello specifico per una condizione
di lavoro, che verrà chiamata nominale. Quindi, il sistema finale presentava diverse etero-
geneità rispetto le diverse condizioni di lavoro. In più, situazioni lontane da quella nom-
inale portavano quasi al sovraccarico della memoria esterna, una condizione da evitare
assolutamente.
L’idea di questo progetto è di affiancare al precedente controllo un algoritmo di identifi-
cazione, in modo tale da avere un controllore che cambi i propri parametri per soddisfare
sempre le specifiche in qualsiasi quadro lavorativo. In questo lavoro vengono discussi e
testati in ambiente simulativo (SIMULINK) tre algoritmi diversi. Poi vengono mostrati
anche gli esperimenti sulla vera struttura, ma qui viene testato solo uno dei tre algoritmi.
Alla fine, c’è un confronto tra il PI e il PI Adattivo. In questa parte è possible vedere
come i risultati del nuovo controllore sono più omogenei rispetto ai precedenti e come il
sovraccarico viene evitato. Però, il nuovo sistema tende ad essere più lento del precedente.This thesis focuses on the maximal usage of an High-Performance Computing (HPC)
Cluster with particular attention to the overloading of the storage, namely the file server.
HPCs have become important in the scientific domain because of their computational
power which allows calculation that otherwise would be impossible with a single computer.
On the other hand, this powered structure has a considerable cost, and unfortunately also
a short life cycle. As a consequence, it becomes important to use as best as possible all
the resources that this new structure gives. In this context, Autonomic Computing and
the collaboration between control theory and computer science were born.
This Mater Thesis continues a broader project where a PI controller was designed for
an HPC Cluster. The aim of the controller is the minimization of idle resources inside
the cluster. However, the controller is built on a model in a nominal configuration which
leads to heterogeneous results for different working conditions. Moreover, conditions far
from the nominal one bring the file server close to the overloading which is a challenging
condition for the system.
The idea of this project is to design an identification algorithm in order to end up with
an Adaptive PI that changes its own parameters to achieve specification with various
working conditions. We design three different algorithms that are going to be tested in a
simulation environment (SIMULINK) and then only one will be carried to the real set-up.
In the end, there is a comparison between the PI and the Adaptive PI. Here it is shown
how the Adaptive PI has a more homogeneous result than the case of the simple PI and
how the overloading of the file server is avoided. However, the drawback is the settling
time which becomes larger than in the case of classic PI
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.
