Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
The spectral temperature of optically thick outflows with application to light echo spectra from η Carinae’s giant eruption
Publisher's PDFThe detection by Rest et al. of light echoes from
η
Carinae has provided important new
observational constraints on the nature of its 1840s era giant eruption. Spectra of the echoes
suggest a relatively cool spectral temperature of about 5500 K, lower than the lower limit of
about 7000 K suggested in the optically thick wind-outflow analysis of Davidson. This has
led to a debate about the viability of this steady wind model relative to alternative, explosive
scenarios. Here we present an updated analysis of the wind-outflow model using newer low-
temperature opacity tabulations and accounting for the stronger mass-loss implied by the
>
10 M
mass now inferred for the Homunculus. A major conclusion is that, because of the
sharp drop in opacity due to recombination loss of free electrons for
T
<
6500 K, a low
temperature of about 5000 K is compatible with, and indeed expected from, a wind with
the extreme mass-loss inferred for the eruption. Within a spherical grey model in radiative
equilibrium, we derive spectral energy distributions for various assumptions for the opacity
variation of the wind, providing a basis for comparisons with observed light echo spectra.
The scaling results here are also potentially relevant for other highly optically thick outflows,
including those from classical novae, giant eruptions of luminous blue variables and supernovae
Type IIn precursors. A broader issue therefore remains whether the complex, variable features
observed from such eruptions are better understood in terms of a steady or explosive paradigm,
or perhaps a balance of these idealizations.University of Delaware. Department of Physics and Astronomy.University of Delaware. Bartol Research Institute
Variations on the Author
“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
We 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
