A community-led calibration of the Zr isotope Reference Materials: NIST candidate RM 8299 and SRM 3169
Get PDFAs the field of Zr stable isotopes is rapidly expanding from the study of
mass-independent to that of mass-dependent isotope effects, a variety of Zr
standards have appeared in the literature. While several of these standards
have been proposed as the ideal isotope reference material (iRM) against which
all data should be reported, none of them have been shown to meet the
compositional and/or conflict-of-interest-free distribution requirements put
forth by the community. To remedy this situation, we report on a community-led
effort to develop and calibrate a scale defining iRM for Zr isotopes: NIST RM
8299. Developed in partnership with the National Institute of Standards and
Technology (NIST) from the widely used SRM 3169 Zr Standard Solution, the
candidate RM 8299 was calibrated through an inter-laboratory study involving
three laboratories. Our data show that RM 8299 meets all requirements of an
ideal iRM. It is an isotopically homogeneous, high-purity reference material,
that is free of isotope anomalies, and whose composition is identical to that
of a major geological reservoir (Ocean Island Basalts). Furthermore, RM 8299
will be curated and distributed by NIST, a neutral, conflict-of-interest free
organization, and was produced in sufficient quantities to last multiple
decades. We recommend that all Zr isotope data to be reported against RM 8299.
Our results also show that SRM 3169 lots #130920 and #071226 have identical
composition to RM 8299. Therefore, using RM 8299 as the scale defining iRM will
enable direct comparison of all future data with the vast majority of the
existing literature data, both for mass-independent and mass-dependent isotope
effects. To facilitate conversion of d94/90Zr values reported against other Zr
standards, we provide high-precision conversion factors to the RM 8299 scale

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
