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
Shear modulus relaxation of bulk metallic glass, Pd₄₀Ni₄₀P₂₀, near the glass temperature
No full textThe non-exponential and non-linear behavior of relaxing glasses below the glass temperature, Tg, is a well known and poorly understood phenomena that is the subject of much experimental and theoretical effort. The Interstitialcy Theory, which describes glasses as perfect crystals with a few percent of interstitialcy defects, provides an atomic insight into the nature of relaxing glasses. The shear modulus, G, is uniquely sensitive to interstitialcies and provides a convenient way to monitor their changing concentrations.
A non-contact EMAT technique is used to excite and detect a shear wave resonance in bulk amorphous metallic glass Pd40Ni40P20 during and after a small sudden change in temperature. A shear modulus relaxation is observed with enough precision to determine how its time constant, t , changes as the relaxation progresses. The results discriminate against models of glassy relaxation commonly found in the literature and are consistent with the Interstitialcy Theory.Submitted by Rachelle Ramer ([email protected]) on 2012-06-28T22:04:41Z

A Study of the Omega-Zero Spin-Density Matrix Elements in the Reaction Pi-Minus Proton Goes to Omega-Zero Neutron at 3.65, 4.5, and 5.5 GeV/c
No full textA study was made of the WO spin-density matrix elements in the o
reaction TI p~ n. The data were collected using a combination of scintillation counters and optical spark chambers designed to detect events of the type
+ TI
p-TI TI yyn. Incident pions of momenta 3.65, 4.5, and 5.5 GeV/c were produced by an internal target at the Argonne National Laboratory Zero Gradient Synchrotron. The values obtained for the WO spin-density matrix elements are inconsistent with the predictions of a simple model which allows for Reggeized p(765) and B(1235) exchange.Submitted by Rachelle Ramer ([email protected]) on 2012-01-20T23:16:00Z

Dº decays from e+e- collisions: precision, rare and substructure results
No full textThree analyses of D0 meson decays are presented which use the data collected with the CLEO II detector at the Cornell Electron Storage Ring. First, a precision measurement of the ratio of the Dº → K-π+πº branching fraction to that of Dº → K-π+ is performed resulting in the best measurement to date. Second, a detailed high statistics study of the underlying resonant structure of the three body decay, Dº → K-π+πº, is carried out. The resulting Dalitz plot is well fi t by the inclusion of seven resonances, along with a non-resonant three body decay component. Finally a search for the radiative decays of the Dº meson is presented along with the four upper limits obtained.Submitted by Rachelle Ramer ([email protected]) on 2012-06-28T22:59:03Z

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
