Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Searches for a high-mass Higgs boson produced in ppbar collisions at sqrt{s}=1.96 TeV
No full textIn this Thesis the electro-weak spontaneous symmetry breaking of the
Standard Model (SM) is studied by searching for the scalar Higgs particle
in the proton antiproton collisions of the Tevatron collider,
at the center of mass energy TeV.
We report on the inclusive search for the Higgs boson
%produced in all processes with significant production rate and
decaying to two bosons in the final state characterized by two charged leptons ( or ) and two neutrinos.
% in collisions at a center of mass energy TeV.
The analysis of 4.8\ifb of data recorded by the Collider Detector at Fermilab (CDF)
shows no evidence of its production. We set 95\% Confidence Level upper limits
on the production cross section as a function of the mass in the range
to 200\gev/c^2.
For m_H=165\gev/c^2 the observed limit is 1.3 times the SM predicted
cross section (); the expected limit, in absence of signal, is .
These limits are the most stringent ones set by a single experiment up to date, for m_H > 130\gev/c^2.In questa Tesi \`e studiato il meccanismo di rottura spontanea di simmetria

L'analisi effettuata su 4.8\ifb di dati raccolti dall'esperimento Collider Detector at Fermilab (CDF)
non mostra alcuna evidenza della sua produzione. Sono quindi calcolati
i limiti al 95\% di Livello di Confidenza sulla sezione d'urto
di produzione di tale particella, in funzione della sua massa , nell'intervallo

Per m_H=165\gev/c^2 il limite osservato \`e 1.3 volte la sezione d'urto

I risultati mostrati in questa Tesi sono, ad oggi, i pi\`u stringenti limiti ottenuti
da un singolo esperimento sulla produzione del bosone di Higgs

Asymptotic analysis for periodic perforated shells
No full textWe consider a perforated half-cylindrical thin shell and investigate the limit behavior when the period and the thickness simultaneously go to zero. By using the decomposition of shell displacements presented in Griso [JMPA 89 (2008) 199–223] we obtain a priori estimates. With the unfolding and rescaling operator we transform the problem to a reference configuration. In the end this yields a homogenized limit problem for the shell
